PROSPECTUS SUMMARY

This summary highlights some important information from this prospectus, and it may not contain all of the information that is important to you. You should read the following summary together with the more detailed information regarding us and our common stock being sold in this offering, including “Risk Factors” and our financial statements and related notes, included elsewhere in this prospectus.

Our Company

We are a development stage biotechnology company with the intent to develop safe and effective cancer vaccines that utilize multiple mechanisms of immunity. We are developing a live Listeria vaccine technology under license from the University of Pennsylvania, which we refer to as Penn, which secretes a protein sequence containing a tumor-specific antigen. We believe this vaccine technology is capable of stimulating the body’s immune system to process and recognize the antigen as if it were foreign, generating an immune response able to attack the cancer. We believe this to be a broadly enabling platform technology that can be applied to the treatment of many types of cancers, infectious diseases and auto-immune disorders.

The discoveries that underlie this innovative technology are based upon the work of Yvonne Paterson, Ph.D., Professor of Microbiology at Penn. This technology involves the creation of genetically engineered Listeria that stimulate the immune system to induce antigen-specific anti-tumor immune response involving both innate and adaptive arms of the immune system. In addition, this technology facilitates the immune response by altering tumors to make them more susceptible to immune attack, and increasing the number and maturation of development of specific cells that underlie a strong therapeutic immune response.

We have focused our initial development efforts upon therapeutic cancer vaccines targeting cervical cancer, its predecessor condition, cervical intraepithelial neoplasia, which we refer to as CIN, head and neck cancer, breast cancer, prostate cancer, and other cancers. Our lead products in development are as follows:

Product	Indication	Stage
ADXS11-001	Cervical Cancer	Phase I Company sponsored & completed in 2007.

	Cervical Intraepithelial Neoplasia	Phase II Company sponsored study, commenced in March 2010 (with patient dosing having commenced in June 2010).

	Cervical Cancer	Phase II Company sponsored study initiated in November 2010 in India. 110 Patients with advanced cervical cancer.

	Cervical Cancer	Phase II The Gynecologic Oncology Group of the National Cancer Institute has agreed to conduct a study which we expect will commence in early 2011.

	Head & Neck Cancer	Phase I The Cancer Research UK (CRUK) is funding a study of up to 45 patients at 3 UK facilities that we expect will commence in early 2011.

ADXS31-142	Prostate Cancer	Phase I Company sponsored (timing to be determined).

ADXS31-164	Breast Cancer	Phase I Company sponsored (timing to be determined).

ADXS31-164	Canine Osteosarcoma	Phase I Company sponsored (timing to be determined).

We have sustained losses from operations in each fiscal year since our inception, and we expect these losses to continue for the indefinite future, due to the substantial investment in research and development. As of October 31, 2010 and April 30, 2011, we had an accumulated deficit of $27,416,000 and $36,294,750, respectively and shareholders’ deficiency of $14,802,631 and $22,238,081, respectively.

To date, we have outsourced many functions of drug development including manufacturing and clinical trials management. Accordingly, the expenses of these outsourced services account for a significant amount of our accumulated loss. We cannot predict when, if ever, any of our product candidates will become commercially viable or approved by the United States Food and Drug Administration, which we refer to as the FDA. We expect to spend substantial additional sums on the continued administration and research and development of proprietary products and technologies, including conducting clinical trials for our product candidates, with no certainty that our products will become commercially viable or profitable as a result of these expenditures.

We intend to continue to devote a substantial portion of our resources to the continued pre-clinical development and optimization of our technology so as to develop it to its full potential and to find appropriate new drug candidates. Specifically, we intend to conduct research relating to developing our Listeria technology using new tumor antigens, and to develop new strains of Listeria, which may lead to additional cancer and infectious disease products, to improve the Listeria platform by developing new Listeria strains that are more suitable as live vaccine vectors, and to continue to develop the use of the Listeria virulence factor LLO as a component of a fusion protein based vaccine. These activities may require significant financial resources, as well as areas of expertise beyond those readily available. In order to provide additional resources and capital, we may enter into research, collaborative or commercial partnerships, joint ventures, or other arrangements with competitive or complementary companies, including major international pharmaceutical companies or universities.

Recent Developments

Preferred Equity Financings

On September 24, 2009, we entered into a Series A preferred stock purchase agreement with Optimus, which we refer to as the Series A purchase agreement, pursuant to which Optimus agreed to purchase, upon the terms and subject to the conditions set forth therein, up to $5.0 million of non-convertible, redeemable Series A preferred stock, which we refer to as our Series A preferred stock, at a price of $10,000 per share. As of May 13, 2010, we issued and sold to Optimus all 500 shares of Series A preferred stock. On July 19, 2010, we issued 500 shares of non-convertible, redeemable Series B preferred stock to Optimus, which we refer to as the Series B exchange shares, in exchange for such 500 shares of Series A preferred stock so that all shares of our preferred stock held or subsequently purchased by Optimus under the Series B purchase agreement described below, would be redeemable upon substantially identical terms.

In connection with the Series A preferred equity financing, on September 24, 2009, we also issued to an affiliate of Optimus a warrant to purchase up to 33,750,000 shares of our common stock at an exercise price of $0.20 per share, which exercise price was subject to adjustment in connection with the sale of each tranche of Series A preferred stock under the Series A purchase agreement. We refer to such warrant as the initial Series A warrant. On January 11, 2010, March 29, 2010 and May 13, 2010, the affiliate of Optimus exercised a portion of the initial Series A warrant to purchase shares of our common stock in the amounts of 11,563,000 (at an adjusted exercise price of $0.17 per share), 14,580,000 (at an exercise price of $0.20 per share) and 7,607,000 (at an adjusted exercise price of $0.18 per share), respectively. As permitted by the terms of the initial Series A warrant, the respective aggregate exercise prices of $1,965,710, $2,916,000 and $1,369,260 were paid to us pursuant to four year full recourse promissory notes, each bearing interest at the rate of 2% per year. In addition, in connection with the sale of the final tranche of Series A preferred stock under the Series A purchase agreement, on May 13, 2010, we issued to an affiliate of Optimus an additional warrant to purchase up to 2,818,000 shares of our common stock on substantially the same terms as the initial Series A warrant. We refer to such warrant as the additional Series A warrant. None of the foregoing promissory notes are due or payable at any time that (a) we are in default under the Series A preferred stock purchase agreement, any loan agreement or other material agreement or (b) there are any Series B exchange shares issued or outstanding. In addition, the affiliate of Optimus is not required to make any payments to us in the event that the shares of common stock acquired upon exercise of the initial Series A warrant are sold prior to repayment of such promissory notes.

On July 19, 2010, we entered into a Series B preferred stock purchase agreement with Optimus, which was subsequently amended on April 4, 2011. We refer to the Series B preferred stock purchase agreement, as amended, as the Series B purchase agreement. Pursuant to the Series B purchase agreement, Optimus agreed to purchase, upon the terms and subject to the conditions set forth therein, up to $7.5 million of non-convertible, redeemable Series B preferred stock, which we refer to as our Series B preferred stock, at a price of $10,000 per share. As of May 15, 2011, we issued and sold to Optimus 466 shares of Series B preferred stock. Under the terms of the Series B purchase agreement, Optimus remains obligated, from time to time until July 19, 2013, to purchase up to an additional 284 shares of Series B preferred stock, subject to the satisfaction of certain conditions, as set forth in the Series B purchase agreement. Among these conditions, we must have a current, valid and effective registration statement covering the resale of all shares of common stock underlying the additional Series B warrant (as described below). Such shares of common stock underlying the additional Series B warrant are being registered pursuant to the registration statement of which this prospectus forms a part.

In connection with the Series B preferred equity financing, on July 19, 2010, we issued to an affiliate of Optimus a warrant to purchase up to 40,500,000 shares of our common stock at an exercise price of $0.25 per share, which exercise price was subject to adjustment in connection with the sale of each tranche of Series B preferred stock under the Series B purchase agreement. We refer to such warrant as the initial Series B warrant. In connection with the amendment to the Series B purchase agreement, on April 4, 2011, we issued to an affiliate of Optimus an additional warrant to purchase up to 25,560,000 shares of our common stock at an exercise price of $0.15 per share, which exercise price is subject to adjustment in connection with the sale of each tranche of Series B preferred stock under the Series B purchase agreement. We refer to such warrant as the additional Series B warrant. The additional Series B warrant is not being issued to the affiliate of Optimus in connection with the sale of the 466 shares of Series B preferred stock described above. If the average closing sale price of our common stock on each tranche notice date is less than $0.15 per share, we may not be able to require Optimus to purchase all of the remaining 284 shares of Series B preferred stock issuable under the Series B purchase agreement without issuing an additional warrant.

On August 13, 2010, September 28, 2010, November 15, 2010, December 30, 2010 and March 14, 2011, the affiliate of Optimus exercised a portion of the initial Series B warrant to purchase shares of our common stock in the amounts of 9,847,059 (at an adjusted exercise price of $0.17 per share), 14,850,000 (at an adjusted exercise price of $0.15 per share), 5,312,903 (at an adjusted exercise price of $0.155 per share), 6,480,000 (at an adjusted exercise price of $0.15 per share) and 3,960,000 (at an adjusted exercise price of $0.15 per share), respectively. On September 22, 2010, the affiliate of Optimus exercised the additional Series A warrant in its entirety (at an adjusted exercise price of $0.18 per share). As permitted by the terms of the initial Series B warrant and the additional Series A warrant, the respective aggregate exercise prices of $1,674,000, $2,227,500, $823,500, $972,000, $594,000 and $507,240 were paid to us pursuant to four year full recourse promissory notes, each bearing interest at the rate of 2% per year. None of the foregoing promissory notes are due or payable at any time that (a) we are in default under the Series B preferred stock purchase agreement, any loan agreement or other material agreement or (b) there are any shares of Series B preferred stock issued or outstanding. In addition, the affiliate of Optimus is not required to make any payments to us in the event that the shares of common stock acquired upon exercise of the foregoing warrants are sold prior to repayment of such promissory notes.

On December 30, 2010, we redeemed 226 shares of Series B preferred stock held by Optimus for an aggregate redemption price of $3,141,004 consisting of (i) cash in an amount of $76,622 and (ii) the cancellation of an aggregate amount of $3,064,382 of the foregoing promissory notes. As of June 3, 2011, 740 shares of our Series B preferred stock and promissory notes in the aggregate amount of $9,998,210 remain outstanding.

May 2011 Note Financing

On May 9, 2011, we entered into a Note Purchase Agreement with certain accredited investors, which we refer to as the May 2011 purchase agreement, whereby the investors acquired approximately $7.0 million of our convertible promissory notes, which we refer to as the May 2011 notes, for an aggregate purchase price of approximately $6.0 million in a private placement, which we refer to as the May 2011 offering. The May 2011 notes were issued with an original issue discount of 15%. Each investor paid $0.85 for each $1.00 of principal amount of May 2011 notes purchased at the closing of the May 2011 offering, which took place on May 12, 2011. The May 2011 notes are convertible into shares of our common stock, at a per share conversion price equal to $0.15. Additionally, each investor received a warrant, which we refer to as the May 2011 warrants, to purchase such number of shares of our common stock equal to 50% of such number of shares of our common stock issuable upon conversion of the May 2011 note at an exercise price of $0.15 per share.

The May 2011 notes mature on May 12, 2012. We may redeem the May 2011 notes under certain circumstances. The May 2011 warrants are exercisable at any time on or before May 12, 2014. The May 2011 warrants may be exercised on a cashless basis under certain circumstances.

To the extent an investor does not elect to convert its May 2011 notes as described above, the principal amount of the May 2011 notes not so converted on or prior to the maturity date shall be payable in cash on the maturity date.

The May 2011 notes may be converted by the investors, at the option of such investor, in whole or in part. However, except as otherwise provided in the May 2011 notes, only 85% of the initial principal amount of each May 2011 note is convertible prior to maturity. The May 2011 notes and May 2011 warrants include a limitation on conversion or exercise, which provides that at no time will an investor be entitled to convert any portion of the May 2011 notes or exercise any of the May 2011 warrants, to the extent that after such conversion or exercise, such investor (together with its affiliates) would beneficially own more than 4.99% of the outstanding shares of our common stock as of such date.

In connection with the May 2011 offering, we entered into a Registration Rights Agreement, dated as of May 9, 2011 with the investors. Pursuant to such agreement, we agreed with the investors to provide certain rights to register under the Securities Act of 1933, as amended, the shares of our common stock issuable upon any conversion of the May 2011 notes and the exercise of the May 2011 warrants, and agreed to file a registration statement within 45 days of the closing of the May 2011 offering to register the offering of the shares of our common stock issuable upon conversion of the May 2011 notes and the exercise of the May 2011 warrants.

Rodman & Renshaw, LLC, which we refer to as Rodman, a subsidiary of Rodman & Renshaw Capital Group, Inc. (NASDAQ:RODM) acted as the exclusive placement agent in connection with the May 2011 offering and received compensation of a cash placement fee equal to 6% of the aggregate purchase price paid by investors in the May 2011 offering and warrants to purchase 1,887,448 shares of our common stock (approximately 4% of the shares of our common stock issuable upon conversion of the May 2011 notes), which warrants are exercisable at $0.15 per share and shall expire on May 12, 2014.

Reduction of Indebtedness

On May 12, 2011, in connection with the closing of the May 2011 offering, we (i) received notices of conversion from holders of an aggregate principal amount of $907,134 of our outstanding senior secured convertible promissory notes and junior unsecured convertible promissory notes pursuant to which we issued or will issue an aggregate of 6,047,561 shares of our common stock to such holders, (ii) entered into exchange agreements with certain other holders of an aggregate principal amount of $152,631 of our outstanding junior unsecured convertible promissory notes, which we refer to as the old notes, pursuant to which we issued an aggregate principal amount of $160,664 of junior unsecured convertible promissory notes, which we refer to as the new notes, in exchange for the old notes and (iii) repaid one junior unsecured convertible promissory note in the aggregate principal amount of $26,316. The new notes are substantially the same as the old notes except that the new notes have an extended maturity date of August 2, 2011. The reduction of indebtedness described above reduced our aggregate amount of outstanding indebtedness from $2,304,984 to $1,405,883.

JMJ Financial Note Issuance

On April 28, 2011 we issued and sold to JMJ Financial, an accredited investor, a convertible promissory note in the aggregate principal amount of $500,000, which we refer to as the series A-note, in return for the payment in cash of $500,000. The series A-note bears interest in the form of a one time interest charge of 8% of the principal amount of such note, payable with the aggregate principal amount outstanding on the maturity date, April 28, 2014. The series A-note is convertible, in whole or in part, into shares of our common stock at a per share conversion price equal to 80% of the average of the two lowest trade prices for our common stock in the 20 trading days previous to the effective date of each such conversion, subject to a conversion floor of $0.15. The series A-note may be prepaid by us without penalty beginning twelve months after its issue date. To the extent the series A-note is not converted as described above, the principal amount of such note not so converted shall be payable in cash on the maturity date.

On April 28, 2011, we also issued and sold to JMJ Financial a convertible promissory note in the aggregate principal amount of $800,000, which we refer to as the series B-note. The series B-note bears interest in the form of a one time interest charge of 8% of the principal amount of such note, payable with the aggregate principal amount outstanding on the maturity date, April 28, 2014. All or any portion of the aggregate principal and interest outstanding under the series B-note is convertible, at the option of JMJ Financial from time to time (subject to the prior pre-payment of a principal amount of a promissory note issued by JMJ Financial to us (which is described below) equal to the principal amount of the series B-note subject to such conversion), into shares of our common stock, at a per share conversion price equal to 80% of the average of the two lowest trade prices for our common stock in the 20 trading days previous to the effective date of each such conversion, subject to a conversion floor of $0.15.

Concurrently with the issuance of the series B-note, JMJ Financial issued and delivered to us a secured and collateralized promissory note, which we refer to as the series C-note, which served as the sole consideration paid to us for the issuance of the series B-note to JMJ Financial. The series C-note was issued in the aggregate principal amount of $800,000, bears interest in the form of a one time interest charge of 8% of the principal amount of such note, payable with aggregate principal amount outstanding on the maturity date, April 28, 2014. The series C-note is to be secured by $800,000 of an unspecified money market fund, or other assets, having a value of at least $800,000.

Immediately after the purchase by JMJ Financial of the series B-note for the series C-note, JMJ Financial delivered to us the sum of $80,000 in cash as a pre payment on the principal amount outstanding under series C-note. While no further mandatory principal or interest payments are due on the series C-note until its maturity date, the series C-note contemplates (but does not require) further voluntary pre payments by JMJ Financial on the series C-note to us at the approximate rate of $250,000 per month, beginning seven months after the issuance of the series C-note, or commencing on or about November 28, 2011, but only provided: (i) all requests by JMJ Financial for conversion of principal and interest on the series B-note are honored and (ii) our common stock issued upon such conversions of portions of the principal and interest on the series B-note may be freely resold by JMJ Financial without the requirement of any restrictive legend pursuant to applicable securities laws, rules and regulations.

Additionally, JMJ Financial may purchase up to an additional $2.4 million in aggregate principal amount of notes in the form of the series B-note from us, which we refer to as the additional series B-notes. The purchase price for each such additional series B-note issued to JMJ Financial will be paid by the issuance by JMJ Financial to us of an additional note in the form of the series C-note, which we refer to as the additional series C-notes, with such additional series B-notes and additional series C-notes containing the same terms and provisions described above.

Recent Bridge Financings

From February 1, 2011 through March 15, 2011, we issued to certain accredited investors (i) junior unsecured convertible promissory notes in the aggregate principal face amount of $246,000, for an aggregate net purchase price of $225,000 and (ii) warrants to purchase 487,500 shares of our common stock at an exercise price of $0.17 per share, subject to adjustments upon the occurrence of certain events. These notes were issued with original issue discounts ranging from 5% to 10% and are convertible into shares of our common stock. These notes have maturity dates ranging from April 30, 2011 to September 30, 2011. The indebtedness represented by these notes is expressly subordinate to our currently outstanding senior secured indebtedness (including the senior convertible promissory notes issued in June 2009, which we refer to as the senior bridge notes), as well as any future senior indebtedness of any kind. We will not make any payments to the holders of these notes until the earlier of the repayment in full or conversion of the senior indebtedness.

In March 2011, we repaid two junior unsecured convertible promissory notes in the aggregate principal amounts of $29,412 and $105,263, respectively, which had been originally issued in January 2010 and November 2010, respectively.

Recent Warrant Exchanges

In an effort to reduce the number of our October 2007 warrants outstanding, we may from time to time enter into exchange agreements with the holders of such warrants pursuant to which such holders may receive shares of our common stock and/or additional warrants in amounts to be determined in such negotiations. As of June 20, 2011, we have exchanged October 2007 warrants to purchase 16,644,446 shares of our common stock with certain investors in return for 2,774,074 shares of our common stock and warrants to purchase an additional 11,096,297 shares of our common stock (which warrants are identical to the October 2007 warrants, except that such warrants do not contain any economic anti-dilution adjustment rights).

Our History

We were originally incorporated in the State of Colorado on June 5, 1987 under the name Great Expectations, Inc. We were administratively dissolved on January 1, 1997 and reinstated on June 18, 1998 under the name Great Expectations and Associates, Inc. In 1999, we became a reporting company under the Securities Exchange Act of 1934, as amended. We were a publicly-traded “shell” company without any business until November 12, 2004 when we acquired Advaxis, Inc., a Delaware corporation, through a Share Exchange and Reorganization Agreement, dated as of August 25, 2004, which we refer to as the Share Exchange, by and among Advaxis, the stockholders of Advaxis and us. As a result of the Share Exchange, Advaxis became our wholly-owned subsidiary and our sole operating company. On December 23, 2004, we amended and restated our articles of incorporation and changed our name to Advaxis, Inc. On June 6, 2006, our shareholders approved the reincorporation of our company from Colorado to Delaware by merging the Colorado entity into our wholly-owned Delaware subsidiary.

(1) These shares represent approximately 11.1% of our currently outstanding shares of common stock (based on 230,083,519 shares of common stock outstanding as of June 20, 2011). These shares also represent approximately 6.0% of our currently outstanding shares of common stock (based on 425,625,749 shares of common stock outstanding as of June 20, 2011) on a fully diluted basis.

RISK FACTORS

An investment in our common stock is highly speculative, involves a high degree of risk and should be made only by investors who can afford a complete loss of their investment. You should carefully consider, together with the other matters referred to in this prospectus, the following risk factors before you decide whether to buy our common stock.

Risks Related to our Business

We are a development stage company.

We are an early stage development stage company with a history of losses and can provide no assurance as to future operating results. As a result of losses which will continue throughout our development stage, we may exhaust our financial resources and be unable to complete the development of our production. Our deficit will continue to grow during our drug development period.

We have sustained losses from operations in each fiscal year since our inception, and we expect losses to continue for the indefinite future, due to the substantial investment in research and development. As of October 31, 2010 and April 30, 2011, we had an accumulated deficit of $27,416,000 and $36,294,750, respectively and shareholders’ deficiency of $14,802,631 and $22,238,081, respectively. We expect to spend substantial additional sums on the continued administration and research and development of proprietary products and technologies with no certainty that our products will become commercially viable or profitable as a result of these expenditures.

As a result of our current lack of financial liquidity and negative stockholders equity, our auditors have expressed substantial concern about our ability to continue as a “going concern” .

Our limited capital resources and operations to date have been funded primarily with the proceeds from public and private equity and debt financings, NOL and Research tax credits and income earned on investments and grants. Based on our currently available cash, we do not have adequate cash on hand to cover our anticipated expenses for the next 12 months. If we fail to raise a significant amount of capital, we may need to significantly curtail operations, cease operations or seek federal bankruptcy protection in the near future. These conditions have caused our auditors to raise substantial doubt about our ability to continue as a going concern. Consequently, the audit report prepared by our independent public accounting firm relating to our financial statements for the year ended October 31, 2010 included a going concern explanatory paragraph.

There can be no assurance that we will receive funding from Optimus in connection with the Series B preferred equity financing.

We have entered into the Series B purchase agreement, as amended, pursuant to which Optimus remains obligated to purchase $2.84 million of our Series B preferred stock from time to time, subject to our ability to effect and maintain an effective registration statement for the remaining 25,610,038 shares underlying the warrants issued to an affiliate of Optimus issued in connection with the transaction. As of June 20, 2011, Optimus had purchased an aggregate of 466 shares of Series B preferred stock and remains obligated, from time to time until July 19, 2013, to purchase up to an additional 284 shares of Series B preferred stock, for an aggregate purchase price of $2,840,000, upon notice from us to Optimus, if certain conditions set forth in the Series B purchase agreement, as amended, are satisfied, including among other things that: (i) we must be in compliance with our SEC reporting obligations, (ii) our common stock must be quoted on an eligible trading market, (iii) a material adverse effect relating to, among other things, our results of operations, assets, business or financial condition must not have occurred since July 19, 2010, other than losses incurred in the ordinary course of business, (iv) we must not be in default under any material agreement, (v) Optimus and its affiliates must not own more than 9.99% of our outstanding common stock, and (vi) we must comply with certain other requirements set forth in the Series B purchase agreement, as amended. If we fail to comply with any of these requirements, Optimus will not be obligated to purchase our Series B preferred stock and we will not receive any funding from Optimus. Moreover, if we exercise our option to require Optimus to purchase our Series B preferred stock, and our common stock has a closing price of less than $0.15 per share on the trading day immediately preceding our delivery of the exercise notice, we may trigger at closing certain anti-dilution protection provisions in certain outstanding warrants that would result in an adjustment to the number and price of certain outstanding warrants.

If the average closing sale price of our common stock on each tranche notice date is less than $0.15 per share, we may not be able to require Optimus to purchase the entire $7.5 million of Series B preferred stock issuable under the Series B purchase agreement, as amended.

In connection with our Series B preferred equity financing, we originally issued to an affiliate of Optimus a three-year warrant to purchase up to 40,500,000 shares of our common stock, at an initial exercise price of $0.25 per share, of which 50,038 shares of our common stock remain available to purchase. In connection with the amendment to the Series B purchase agreement, we subsequently issued to an affiliate of Optimus a three-year warrant to purchase up to an additional 25,560,000 shares of our common stock, at an initial exercise price of $0.15 per share. The warrants provide that on each tranche notice date under the Series B purchase agreement, as amended, (i) that portion of the warrants, in the aggregate, equal to 135% of the tranche amount will vest and become exercisable (and such vested portion may be exercised at any time during the exercise period on or after such tranche notice date) and (ii) the exercise price will be adjusted to the closing sale price of a share of our common stock on such tranche notice date. We are not permitted to deliver a tranche notice under the Series B purchase agreement, as amended, and require Optimus to purchase shares of Series B preferred stock if the number of registered shares underlying the warrant issued to the affiliate of Optimus is insufficient to cover the portion of the warrant that will vest and become exercisable in connection with such tranche notice. If the average closing sale price of our common stock on each tranche notice date is less than $0.15 per share, we may not be able to require Optimus to purchase the remaining $2.84 million of Series B preferred stock issuable under the Series B purchase agreement, as amended, without issuing additional warrant shares. We cannot assure you that we will be able to timely effect and maintain a registration statement for the remaining 25,610,038 warrant shares (or any additional warrant shares that may be necessary) so as to permit us to require Optimus to purchase the remaining $2,840,000 of Series B preferred stock under the Series B purchase agreement, as amended.

We expect to continue to spend substantial amounts on research and development, including conducting clinical trials for our product candidates. However, we will not have sufficient resources to develop fully any new products or technologies unless we are able to raise substantial additional financing on acceptable terms, secure funds from new partners or consummate a preferred equity financing under the Series B purchase agreement, as amended. We cannot be assured that financing will be available at all. Our failure to raise a significant amount of capital in the near future, will materially adversely affect our business, financial condition and results of operations, and we may need to significantly curtail operations, cease operations or seek federal bankruptcy protection in the near future. Any additional investments or resources required would be approached, to the extent appropriate in the circumstances, in an incremental fashion to attempt to cause minimal disruption or dilution. Any additional capital raised through the sale of equity or convertible debt securities will result in dilution to our existing stockholders. No assurances can be given, however, that we will be able to achieve these goals or that we will be able to continue as a going concern.

We have significant indebtedness which may restrict our business and operations, adversely affect our cash flow and restrict our future access to sufficient funding to finance desired growth.

As of May 31, 2011, our total outstanding indebtedness was approximately $9.6 million, which included the face value of all our outstanding junior bridge notes in the amount of approximately $1.0 million, a note outstanding to our chief executive officer in the amount of approximately $0.9 million and debt acquired in late April and early May 2011 in the aggregate principal amount of approximately $7.7 million. Approximately $7.1 of the $9.6 million is due on May 12, 2012. Maturity dates for the remaining $2.5 million range between August 2, 2011 and on or about April 30, 2014. Certain of our indebtedness contain restrictive covenants that limit our ability to issue certain types of indebtedness, which may prevent us from obtaining additional indebtedness on commercially reasonable terms, or at all. We dedicate a substantial portion of our cash to pay interest and principal on our debt. If we are not able to service our debt, we would need to refinance all or part of that debt, sell assets, borrow more money or sell securities, which we may not be able to do on commercially reasonable terms, or at all. In addition, our failure to timely repay (or extend) amounts due and owing under our outstanding senior bridge notes and the junior bridge notes issued in October 2009 may trigger the anti-dilution protection provisions in substantially all of our warrants (other than the warrants issued to the affiliate of Optimus and to certain bridge note holders), in which case holders of our common stock will experience significant additional dilution.

The terms of our notes include customary events of default and covenants that restrict our ability to incur additional indebtedness. These restrictions and covenants may prevent us from engaging in transactions that might otherwise be considered beneficial to us. A breach of the provisions of our indebtedness could result in an event of default under our outstanding notes. If an event of default occurs under our notes (after any applicable notice and cure periods), the holders would be entitled to accelerate the repayment of amounts outstanding, plus accrued and unpaid interest. In the event of a default under our senior indebtedness, the holders could also foreclose against the assets securing such obligations. In the event of a foreclosure on all or substantially all of our assets, we may not be able to continue to operate as a going concern.

Our limited operating history does not afford investors a sufficient history on which to base an investment decision.

We commenced our Listeria System vaccine development business in February 2002 and have existed as a development stage company since such time. Prior thereto we conducted no business. Accordingly, we have a limited operating history. Investors must consider the risks and difficulties we have encountered in the rapidly evolving vaccine and therapeutic biopharmaceutical industry. Such risks include the following:

competition from companies that have substantially greater assets and financial resources than we have;

need for acceptance of products;

ability to anticipate and adapt to a competitive market and rapid technological developments;

amount and timing of operating costs and capital expenditures relating to expansion of our business, operations and infrastructure;

need to rely on multiple levels of complex financing agreements with outside funding due to the length of the product development cycles and governmental approved protocols associated with the pharmaceutical industry; and

dependence upon key personnel including key independent consultants and advisors.

We cannot be certain that our strategy will be successful or that we will successfully address these risks. In the event that we do not successfully address these risks, our business, prospects, financial condition and results of operations could be materially and adversely affected. We may be required to reduce our staff, discontinue certain research or development programs of our future products and cease to operate.

We can provide no assurance of the successful and timely development of new products.

Our products are at various stages of research and development. Further development and extensive testing will be required to determine their technical feasibility and commercial viability. Our success will depend on our ability to achieve scientific and technological advances and to translate such advances into reliable, commercially competitive products on a timely basis. Immunotherapy and vaccine products that we may develop are not likely to be commercially available until five to ten or more years. The proposed development schedules for our products may be affected by a variety of factors, including technological difficulties, proprietary technology of others, and changes in governmental regulation, many of which will not be within our control. Any delay in the development, introduction or marketing of our products could result either in such products being marketed at a time when their cost and performance characteristics would not be competitive in the marketplace or in the shortening of their commercial lives. In light of the long-term nature of our projects, the unproven technology involved and the other factors described elsewhere in “Risk Factors,” there can be no assurance that we will be able to successfully complete the development or marketing of any new products.

Our research and development expenses are subject to uncertainty.

Factors affecting our research and development expenses include, but are not limited to:

competition from companies that have substantially greater assets and financial resources than we have;

need for acceptance of products;

ability to anticipate and adapt to a competitive market and rapid technological developments;

amount and timing of operating costs and capital expenditures relating to expansion of our business, operations and infrastructure;

need to rely on multiple levels of outside funding due to the length of the product development cycles and governmental approved protocols associated with the pharmaceutical industry; and

dependence upon key personnel including key independent consultants and advisors.

We are subject to numerous risks inherent in conducting clinical trials.

We outsource the management of our clinical trials to third parties. Agreements with clinical investigators and medical institutions for clinical testing and with other third parties for data management services, place substantial responsibilities on these parties which, if unmet, could result in delays in, or termination of, our clinical trials. For example, if any of our clinical trial sites fail to comply with FDA-approved good clinical practices, we may be unable to use the data gathered at those sites. If these clinical investigators, medical institutions or other third parties do not carry out their contractual duties or obligations or fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols or for other reasons, our clinical trials may be extended, delayed or terminated, and we may be unable to obtain regulatory approval for or successfully commercialize our agent ADXS11-001. We are not certain that we will successfully recruit enough patients to complete our clinical trials. Delays in recruitment and such agreements would delay the initiation of the Phase II trials of ADXS11-001.

We or our regulators may suspend or terminate our clinical trials for a number of reasons. We may voluntarily suspend or terminate our clinical trials if at any time we believe they present an unacceptable risk to the patients enrolled in our clinical trials. In addition, regulatory agencies may order the temporary or permanent discontinuation of our clinical trials at any time if they believe that the clinical trials are not being conducted in accordance with applicable regulatory requirements or that they present an unacceptable safety risk to the patients enrolled in our clinical trials.

Our clinical trial operations are subject to regulatory inspections at any time. If regulatory inspectors conclude that we or our clinical trial sites are not in compliance with applicable regulatory requirements for conducting clinical trials, we may receive reports of observations or warning letters detailing deficiencies, and we will be required to implement corrective actions. If regulatory agencies deem our responses to be inadequate, or are dissatisfied with the corrective actions we or our clinical trial sites have implemented, our clinical trials may be temporarily or permanently discontinued, we may be fined, we or our investigators may be precluded from conducting any ongoing or any future clinical trials, the government may refuse to approve our marketing applications or allow us to manufacture or market our products, and we may be criminally prosecuted.

The successful development of biopharmaceuticals is highly uncertain.

Successful development of biopharmaceuticals is highly uncertain and is dependent on numerous factors, many of which are beyond our control. Products that appear promising in the early phases of development may fail to reach the market for several reasons including:

Preclinical study results that may show the product to be less effective than desired (e.g., the study failed to meet its primary objectives) or to have harmful or problematic side effects;

Failure to receive the necessary regulatory approvals or a delay in receiving such approvals. Among other things, such delays may be caused by slow enrollment in clinical studies, length of time to achieve study endpoints, additional time requirements for data analysis, or Biologics License Application preparation, discussions with the FDA, an FDA request for additional preclinical or clinical data, or unexpected safety or manufacturing issues;

Manufacturing costs, formulation issues, pricing or reimbursement issues, or other factors that make the product uneconomical; and

The proprietary rights of others and their competing products and technologies that may prevent the product from being commercialized.

Success in preclinical and early clinical studies does not ensure that large-scale clinical studies will be successful. Clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. The length of time necessary to complete clinical studies and to submit an application for marketing approval for a final decision by a regulatory authority varies significantly from one product to the next, and may be difficult to predict.

We must comply with significant government regulations.

The research and development, manufacture and marketing of human therapeutic and diagnostic products are subject to regulation, primarily by the FDA in the U.S. and by comparable authorities in other countries. These national agencies and other federal, state, local and foreign entities regulate, among other things, research and development activities (including testing in animals and in humans) and the testing, manufacturing, handling, labeling, storage, record keeping, approval, advertising and promotion of the products that we are developing. Noncompliance with applicable requirements can result in various adverse consequences, including delay in approving or refusal to approve product licenses or other applications, suspension or termination of clinical investigations, revocation of approvals previously granted, fines, criminal prosecution, recall or seizure of products, injunctions against shipping products and total or partial suspension of production and/or refusal to allow a company to enter into governmental supply contracts.

The process of obtaining requisite FDA approval has historically been costly and time-consuming. Current FDA requirements for a new human biological product to be marketed in the U.S. include: (1) the successful conclusion of preclinical laboratory and animal tests, if appropriate, to gain preliminary information on the product’s safety; (2) filing with the FDA of an Investigational New Drug Application, which we refer to as an IND, to conduct human clinical trials for drugs or biologics; (3) the successful completion of adequate and well-controlled human clinical investigations to establish the safety and efficacy of the product for its recommended use; and (4) filing by a company and acceptance and approval by the FDA of a Biologic License Application, which we refer to as a BLA, for a biological product, to allow commercial distribution of a biologic product. A delay in one or more of the procedural steps outlined above could be harmful to us in terms of getting our product candidates through clinical testing and to market.

We can provide no assurance that our products will obtain regulatory approval or that the results of clinical studies will be favorable.

In February 2006, we received permission from the appropriate governmental agencies in Israel, Mexico and Serbia to conduct Phase I clinical testing in those countries of ADXS11-001, our Listeria -based cancer vaccine that targets cervical cancer in women. The study was completed in the fiscal quarter ended January 31, 2008. The next step was to manufacture and test our product for future sale or distribution in the U.S. which required a filing of an IND with the FDA for our Phase II CIN trial. The filing was based on information from the Phase I trial and other pre-clinical information. On January 6, 2009 we received permission to conduct our clinical trial under this IND from the FDA. However, even though we are allowed to conduct this trial, as with any experimental agent, we are always at risk to be placed on clinical hold by the FDA at any time as our product may have effects on humans are not fully understood or documented. There can be delays in obtaining FDA or any other necessary regulatory approvals of any proposed product and failure to receive such approvals would have an adverse effect on the product’s potential commercial success and on our business, prospects, financial condition and results of operations. In addition, it is possible that a product may be found to be ineffective or unsafe due to conditions or facts which arise after development has been completed and regulatory approvals have been obtained. In this event, we may be required to withdraw such product from the market. To the extent that our success will depend on any regulatory approvals from governmental authorities outside of the U.S. that perform roles similar to that of the FDA, uncertainties similar to those stated above will also exist.

We rely upon patents to protect our technology. We may be unable to protect our intellectual property rights and we may be liable for infringing the intellectual property rights of others.

Our ability to compete effectively will depend on our ability to maintain the proprietary nature of our technologies, including the Listeria System, and the proprietary technology of others with whom we have entered into licensing agreements.

As of June 20, 2011 we have 32 patents that have been issued and licenses for 33 patent applications that are pending (including the 23 patent applications obtained in May 2010). We have licensed most of these patents and applications from Penn and we have obtained the rights to all future patent applications originating in the laboratories of Dr. Yvonne Paterson and Dr. Fred Frankel. Further, we rely on a combination of trade secrets and nondisclosure, and other contractual agreements and technical measures to protect our rights in the technology. We depend upon confidentiality agreements with our officers, employees, consultants, and subcontractors to maintain the proprietary nature of the technology. These measures may not afford us sufficient or complete protection, and others may independently develop technology similar to ours, otherwise avoid the confidentiality agreements, or produce patents that would materially and adversely affect our business, prospects, financial condition, and results of operations. Such competitive events, technologies and patents may limit our ability to raise funds, prevent other companies from collaborating with us, and in certain cases prevent us from further developing our technology due to third party patent blocking rights.

We are aware of a private company, Anza Therapeutics, Inc (formerly Cerus Corporation), which is no longer in existence, but had been developing Listeria vaccines. We are also aware of Aduro Biotech, a company comprised in part of former Cerus and Anza employees that has recently formed to investigate Listeria vaccines. We believe that through our exclusive license with Penn we have earliest known and dominant patent position in the U.S. for the use of recombinant Listeria monocytogenes expressing proteins or tumor antigens as a vaccine for the treatment of infectious diseases and tumors. We successfully defended our intellectual property by contesting a challenge made by Anza to our patent position in Europe on a claim not available in the U.S. The European Patent Office, which we refer to as the EPO, Board of Appeals in Munich, Germany has ruled in favor of The Trustees of Penn and its exclusive licensee Advaxis and reversed a patent ruling that revoked a technology patent that had resulted from an opposition filed by Anza. The ruling of the EPO Board of Appeals is final and cannot be appealed. The granted claims, the subject matter of which was discovered by Dr. Yvonne Paterson, scientific founder of Advaxis, are directed to the method of preparation and composition of matter of recombinant bacteria expressing tumor antigens for treatment of patients with cancer. Based on searches of publicly available databases, we do not believe that Anza, Aduro or any other third party owns any published Listeria patents or has any issued patent claims that might materially and adversely affect our ability to operate our business as currently contemplated in the field of recombinant Listeria monocytogenes. Additionally, our proprietary position that is the issued patents and licenses for pending applications restricts anyone from using plasmid based Listeria constructs, or those that are bioengineered to deliver antigens fused to LLO, ActA, or fragments of LLO or ActA.

We are dependent upon our license agreement with Penn; if we fail to make payments due and owing to Penn under our license agreement, our business will be materially and adversely affected.

Pursuant to the terms of our Second Amendment Agreement with Penn, as amended, we have acquired exclusive licenses for an additional 23 patent applications related to our proprietary Listeria vaccine technology. As of April 30, 2011, we owed Penn approximately $138,000 in patent expenses. We can provide no assurance that we will be able to make all payments due and owing thereunder, that such licenses will not be terminated or expire during critical periods, that we will be able to obtain licenses for other rights which may be important to us, or, if obtained, that such licenses will be obtained on commercially reasonable terms.

If we are unable to maintain and/or obtain licenses, we may have to develop alternatives to avoid infringing on the patents of others, potentially causing increased costs and delays in product development and introduction or precluding the development, manufacture, or sale of planned products. Some of our licenses provide for limited periods of exclusivity that require minimum license fees and payments and/or may be extended only with the consent of the licensor. We can provide no assurance that we will be able to meet these minimum license fees in the future or that these third parties will grant extensions on any or all such licenses. This same restriction may be contained in licenses obtained in the future. Additionally, we can provide no assurance that the patents underlying any licenses will be valid and enforceable. To the extent any products developed by us are based on licensed technology, royalty payments on the licenses will reduce our gross profit from such product sales and may render the sales of such products uneconomical.

We have no manufacturing, sales, marketing or distribution capability and we must rely upon third parties for such.

We do not intend to create facilities to manufacture our products and therefore are dependent upon third parties to do so. We currently have agreements with Recipharm Cobra Biologics Limited, which we refer to as Recipharm Cobra, and Vibalogics GmbH for production of our immunotherapies and vaccines for research and development and testing purposes. Our reliance on third parties for the manufacture of our products creates a dependency that could severely disrupt our research and development, our clinical testing, and ultimately our sales and marketing efforts if the source of such supply proves to be unreliable or unavailable. If the contracted manufacturing source is unreliable or unavailable, we may not be able to replace the development of our product candidates, our clinical testing program may not be able to go forward and our entire business plan could fail.

If we are unable to establish or manage strategic collaborations in the future, our revenue and product development may be limited.

Our strategy includes eventual substantial reliance upon strategic collaborations for marketing and commercialization of ADXS11-001, and we may rely even more on strategic collaborations for research, development, marketing and commercialization of our other product candidates. To date, we have not entered into any strategic collaborations with third parties capable of providing these services although we have been heavily reliant upon third party outsourcing for our clinical trials execution and production of our product for use in clinical trials. In addition, we have not yet marketed or sold any of our product candidates or entered into successful collaborations for these services in order to ultimately commercialize our product candidates. Establishing strategic collaborations is difficult and time-consuming. Our discussion with potential collaborators may not lead to the establishment of collaborations on favorable terms, if at all. For example, potential collaborators may reject collaborations based upon their assessment of our financial, regulatory or intellectual property position. If we successfully establish new collaborations, these relationships may never result in the successful development or commercialization of our product candidates or the generation of sales revenue. To the extent that we enter into co-promotion or other collaborative arrangements, our product revenues are likely to be lower than if we directly marketed and sold any products that we may develop.

Management of our relationships with our collaborators will require:

significant time and effort from our management team;

coordination of our research and development programs with the research and development priorities of our collaborators; and

effective allocation of our resources to multiple projects.

If we continue to enter into research and development collaborations at the early phases of product development, our success will in part depend on the performance of our corporate collaborators. We will not directly control the amount or timing of resources devoted by our corporate collaborators to activities related to our product candidates. Our corporate collaborators may not commit sufficient resources to our research and development programs or the commercialization, marketing or distribution of our product candidates. If any corporate collaborator fails to commit sufficient resources, our preclinical or clinical development programs related to this collaboration could be delayed or terminated. Also, our collaborators may pursue existing or other development-stage products or alternative technologies in preference to those being developed in collaboration with us. Finally, if we fail to make required milestone or royalty payments to our collaborators or to observe other obligations in our agreements with them, our collaborators may have the right to terminate those agreements.

We may incur substantial liabilities from any product liability claims if our insurance coverage for those claims is inadequate.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials, and will face an even greater risk if the product candidates are sold commercially. An individual may bring a liability claim against us if one of the product candidates causes, or merely appears to have caused, an injury. If we cannot successfully defend ourselves against the product liability claim, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

decreased demand for our product candidates;

damage to our reputation;

withdrawal of clinical trial participants;

costs of related litigation;

substantial monetary awards to patients or other claimants;

loss of revenues;

the inability to commercialize product candidates; and

increased difficulty in raising required additional funds in the private and public capital markets.

We have insurance coverage on our Phase II CIN and cervical cancer trials for each clinical trial site. We do not have product liability insurance because we do not have products on the market. We currently are in the process of obtaining insurance coverage and to expand such coverage to include the sale of commercial products if marketing approval is obtained for any of our product candidates. However, insurance coverage is increasingly expensive and we may not be able to maintain insurance coverage at a reasonable cost and we may not be able to obtain insurance coverage that will be adequate to satisfy any liability that may arise.

We may incur significant costs complying with environmental laws and regulations.

We and our contracted third parties will use hazardous materials, including chemicals and biological agents and compounds that could be dangerous to human health and safety or the environment. As appropriate, we will store these materials and wastes resulting from their use at our or our outsourced laboratory facility pending their ultimate use or disposal. We will contract with a third party to properly dispose of these materials and wastes. We will be subject to a variety of federal, state and local laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these materials and wastes. We may also incur significant costs complying with environmental laws and regulations adopted in the future.

If we use biological and hazardous materials in a manner that causes injury, we may be liable for damages.

Our research and development and manufacturing activities will involve the use of biological and hazardous materials. Although we believe our safety procedures for handling and disposing of these materials will comply with federal, state and local laws and regulations, we cannot entirely eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of these materials. We do not carry specific biological or hazardous waste insurance coverage, workers compensation or property and casualty and general liability insurance policies which include coverage for damages and fines arising from biological or hazardous waste exposure or contamination. Accordingly, in the event of contamination or injury, we could be held liable for damages or penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended or terminated.

We need to attract and retain highly skilled personnel; we may be unable to effectively manage growth with our limited resources.

As of June 20, 2011, we had 12 employees, all of which were full time employees. We do not intend to significantly expand our operations and staff unless we get adequate financing. If we receive such funding then our new employees may include key managerial, technical, financial, research and development and operations personnel who will not have been fully integrated into our operations. We will be required to expand our operational and financial systems significantly and to expand, train and manage our work force in order to manage the expansion of our operations. Our failure to fully integrate any new employees into our operations could have a material adverse effect on our business, prospects, financial condition and results of operations.

We operate under an agreement with AlphaStaff, a professional employment organization that provides us with payroll and human resources services. Our ability to attract and retain highly skilled personnel is critical to our operations and expansion. We face competition for these types of personnel from other technology companies and more established organizations, many of which have significantly larger operations and greater financial, technical, human and other resources than we have. We may not be successful in attracting and retaining qualified personnel on a timely basis, on competitive terms, or at all. If we are not successful in attracting and retaining these personnel, our business, prospects, financial condition and results of operations will be materially adversely affected. In such circumstances we may be unable to conduct certain research and development programs, unable to adequately manage our clinical trials and other products, and unable to adequately address our management needs. In addition, from time to time, we are unable to make payroll due to our lack of cash.

We depend upon our senior management and key consultants and their loss or unavailability could put us at a competitive disadvantage.

We depend upon the efforts and abilities of our senior executives, as well as the services of several key consultants, including Yvonne Paterson, Ph.D. The loss or unavailability of the services of any of these individuals for any significant period of time could have a material adverse effect on our business, prospects, financial condition and results of operations. We have not obtained, do not own, nor are we the beneficiary of, key-person life insurance.

Risks Related to the Biotechnology / Biopharmaceutical Industry

The biotechnology and biopharmaceutical industries are characterized by rapid technological developments and a high degree of competition. We may be unable to compete with more substantial enterprises.

The biotechnology and biopharmaceutical industries are characterized by rapid technological developments and a high degree of competition. Competition in the biopharmaceutical industry is based significantly on scientific and technological factors. These factors include the availability of patent and other protection for technology and products, the ability to commercialize technological developments and the ability to obtain governmental approval for testing, manufacturing and marketing. We compete with specialized biopharmaceutical firms in the U.S., Europe and elsewhere, as well as a growing number of large pharmaceutical companies that are applying biotechnology to their operations. Many biopharmaceutical companies have focused their development efforts in the human therapeutics area, including cancer. Many major pharmaceutical companies have developed or acquired internal biotechnology capabilities or made commercial arrangements with other biopharmaceutical companies. These companies, as well as academic institutions and governmental agencies and private research organizations, also compete with us in recruiting and retaining highly qualified scientific personnel and consultants. Our ability to compete successfully with other companies in the pharmaceutical field will also depend to a considerable degree on the continuing availability of capital to us.

We are aware of certain products under development or manufactured by competitors that are used for the prevention, diagnosis, or treatment of certain diseases we have targeted for product development. Various companies are developing biopharmaceutical products that potentially directly compete with our product candidates even though their approach to such treatment is different. The biotechnology and biopharmaceutical industries are highly competitive, and this competition comes from both biotechnology firms and from major pharmaceutical and chemical companies, including Aduro Biotech, Antigenics Inc., Avi BioPharma, Inc., Biomura Inc., Biovest International, Biosante Pharmaceuticals Inc., Dendreon Corporation, Pharmexa-Epimmune Inc. , Genzyme Corp., Progenics Pharmaceuticals Inc. and Vical Incorporated each of which is pursuing cancer vaccines.

We expect that our products under development and in clinical trials will address major markets within the cancer sector with a superior technology that is both safer and more effective than our competitors. Our competition will be determined in part by the potential indications for which drugs are developed and ultimately approved by regulatory authorities. Additionally, the timing of market introduction of some of our potential products or of competitors’ products may be an important competitive factor. Accordingly, the relative speed with which we can develop products, complete preclinical testing, clinical trials and approval processes and supply commercial quantities to market is expected to be important competitive factors. We expect that competition among products approved for sale will be based on various factors, including product efficacy, safety, reliability, availability, price and patent position.

Risks Related to the Securities Markets and Investments in our Common Stock

The price of our common stock may be volatile.

The trading price of our common stock may fluctuate substantially. The price of our common stock that will prevail in the market after the sale of the shares of common stock by the selling stockholder may be higher or lower than the price you have paid, depending on many factors, some of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose part or all of your investment in our common stock. Those factors that could cause fluctuations include, but are not limited to, the following:

price and volume fluctuations in the overall stock market from time to time;

fluctuations in stock market prices and trading volumes of similar companies;

actual or anticipated changes in our net loss or fluctuations in our operating results or in the expectations of securities analysts;

the issuance of new equity securities pursuant to a future offering, including issuances of preferred stock pursuant to the Series B purchase agreement, as amended;

general economic conditions and trends;

major catastrophic events;

sales of large blocks of our stock;

significant dilution caused by the anti-dilutive clauses in our financial agreements;

departures of key personnel;

changes in the regulatory status of our product candidates, including results of our clinical trials;

events affecting Penn or any future collaborators;

announcements of new products or technologies, commercial relationships or other events by us or our competitors;

regulatory developments in the U.S. and other countries;

failure of our common stock to be listed or quoted on the Nasdaq Stock Market, NYSE Amex Equities or other national market system;

changes in accounting principles; and

discussion of us or our stock price by the financial and scientific press and in online investor communities.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Due to the potential volatility of our stock price, we may therefore be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources from our business.

You may have difficulty selling our shares because they are deemed “penny stocks.”

Our common stock is deemed to be “penny stock” as that term is defined in Rule 3a51-1, promulgated under the Exchange Act. Penny stocks are, generally, stocks:

with a price of less than $5.00 per share;

that are neither traded on a “recognized” national exchange nor listed on an automated quotation system sponsored by a registered national securities association meeting certain minimum initial listing standards; and

of issuers with net tangible assets less than $2.0 million (if the issuer has been in continuous operation for at least three years) or $5.0 million (if in continuous operation for less than three years), or with average revenue of less than $6.0 million for the last three years.

Section 15(g) of the Exchange Act and Rule 15g-2 promulgated thereunder require broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document before effecting any transaction in a “penny stock” for the investor’s account. We urge potential investors to obtain and read this disclosure carefully before purchasing any shares that are deemed to be “penny stock.”

Rule 15g-9 promulgated under the Exchange Act requires broker-dealers in penny stocks to approve the account of any investor for transactions in such stocks before selling any “penny stock” to that investor. This procedure requires the broker-dealer to:

obtain from the investor information about his or her financial situation, investment experience and investment objectives;

reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor and that the investor has enough knowledge and experience to be able to evaluate the risks of “penny stock” transactions;

provide the investor with a written statement setting forth the basis on which the broker-dealer made his or her determination; and

receive a signed and dated copy of the statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives.

Compliance with these requirements may make it harder for investors in our common stock to resell their shares to third parties. Accordingly, our common stock should only be purchased by investors, who understand that such investment is a long-term and illiquid investment, and are capable of and prepared to bear the risk of holding our common stock for an indefinite period of time.

A limited public trading market may cause volatility in the price of our common stock.

Our common stock began trading on the OTC Bulletin Board on July 28, 2005 and is quoted under the symbol ADXS.OB. The quotation of our common stock on the OTC Bulletin Board does not assure that a meaningful, consistent and liquid trading market currently exists, and in recent years such market has experienced extreme price and volume fluctuations that have particularly affected the market prices of many smaller companies like us. Our common stock is thus subject to this volatility. Sales of substantial amounts of common stock, or the perception that such sales might occur, could adversely affect prevailing market prices of our common stock and our stock price may decline substantially in a short time and our stockholders could suffer losses or be unable to liquidate their holdings. Also there are large blocks of restricted stock that have met the holding requirements under Rule 144 that can be unrestricted and sold. Our stock is thinly traded due to the limited number of shares available for trading on the market thus causing large swings in price.

There is no assurance of an established public trading market.

A regular trading market for our common stock may not be sustained in the future. The effect on the OTC Bulletin Board of these rule changes and other proposed changes cannot be determined at this time. The OTC Bulletin Board is an inter-dealer, over-the-counter market that provides significantly less liquidity than the Nasdaq Stock Market. Quotes for stocks included on the OTC Bulletin Board are not listed in the financial sections of newspapers. As such, investors and potential investors may find it difficult to obtain accurate stock price quotations, and holders of our common stock may be unable to resell their securities at or near their original offering price or at any price. Market prices for our common stock will be influenced by a number of factors, including:

the issuance of new equity securities pursuant to a future offering, including issuances of preferred stock pursuant to the Series B purchase agreement, as amended;

changes in interest rates;

significant dilution caused by the anti-dilutive clauses in our financial agreements;

competitive developments, including announcements by competitors of new products or services or significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;

variations in quarterly operating results;

change in financial estimates by securities analysts;

the depth and liquidity of the market for our common stock;

investor perceptions of our company and the technologies industries generally; and

general economic and other national conditions.

We may not be able to achieve secondary trading of our stock in certain states because our common stock is not nationally traded.

Because our common stock is not listed for trading on a national securities exchange, our common stock is subject to the securities laws of the various states and jurisdictions of the U.S. in addition to federal securities law. This regulation covers any primary offering we might attempt and all secondary trading by our stockholders. If we fail to take appropriate steps to register our common stock or qualify for exemptions for our common stock in certain states or jurisdictions of the U.S., the investors in those jurisdictions where we have not taken such steps may not be allowed to purchase our stock or those who presently hold our stock may not be able to resell their shares without substantial effort and expense. These restrictions and potential costs could be significant burdens on our stockholders.

If we fail to remain current on our reporting requirements, we could be removed from the OTC Bulletin Board, which would limit the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market.

Companies trading on the OTC Bulletin Board, such as us, must be reporting issuers under Section 12 of the Exchange Act, as amended, and must be current in their reports under Section 13, in order to maintain price quotation privileges on the OTC Bulletin Board. For our third quarter 2009 and fiscal year ended October 31, 2009, we were unable to file our respective quarterly report on Form 10-Q and annual report on Form 10-K in a timely manner, but we were able to make the filings and cure our compliance deficiencies with the OTC Bulletin Board within the grace period allowed by the OTC Bulletin Board. If we fail to remain current on our reporting requirements, we could be removed from the OTC Bulletin Board. As a result, the market liquidity for our securities could be severely adversely affected by limiting the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market. In addition, we may not be able to deliver a tranche notice to Optimus under the Series B purchase agreement.

Our internal control over financial reporting and our disclosure controls and procedures have been ineffective in the past, and may be ineffective again in the future, and failure to improve them at such time could lead to errors in our financial statements that could require a restatement or untimely filings, which could cause investors to lose confidence in our reported financial information, and a decline in our stock price.

Our internal control over financial reporting and our disclosure controls and procedures have been ineffective in the past. We have taken steps to improve our disclosure controls and procedures and our internal control over financial reporting, and as of April 30, 2011, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures and internal control over financial reporting were effective. However, there is no assurance that our disclosure controls and procedures will remain effective or that there will be no material weaknesses in our internal control over financial reporting in the future. Additionally, as a result of the historical material weaknesses in our internal control over financial reporting and the historical ineffectiveness of our disclosure controls and procedures, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our stock.

Our executive officers and directors can exert significant influence over us and may make decisions that do not always coincide with the interests of other stockholders.

As of June 20, 2011, our officers and directors and their affiliates, in the aggregate, beneficially own approximately 12.3% of the outstanding shares of our common stock. As a result, such persons, acting together, have the ability to substantially influence all matters submitted to our stockholders for approval, including the election and removal of directors, any merger, consolidation or sale of all or substantially all of our assets, an increase in the number of shares authorized for issuance under our stock option plans, and to control our management and affairs. Accordingly, such concentration of ownership may have the effect of delaying, deferring or preventing a change in or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of our business, even if such a transaction would be beneficial to other stockholders.

Sales of additional equity securities may adversely affect the market price of our common stock and your rights in us may be reduced.

We expect to continue to incur product development and selling, general and administrative costs, and to satisfy our funding requirements, we will need to sell additional equity securities, which may be subject to registration rights and warrants with anti-dilutive protective provisions. The sale or the proposed sale of substantial amounts of our common stock in the public markets may adversely affect the market price of our common stock and our stock price may decline substantially. Our stockholders may experience substantial dilution and a reduction in the price that they are able to obtain upon sale of their shares. Also, new equity securities issued may have greater rights, preferences or privileges than our existing common stock.

Additional authorized shares of common stock available for issuance may adversely affect the market.

We are authorized to issue 500,000,000 shares of our common stock. As of June 20, 2011, we had 230,083,519 shares of our common stock issued and outstanding, excluding shares issuable upon exercise of our outstanding warrants, options and convertible promissory notes. As of April 30, 2011, we had outstanding options to purchase 27,317,424 shares of our common stock at a weighted average exercise price of approximately $0.16 per share and outstanding warrants to purchase 91,530,196 shares of our common stock (excluding Optimus warrants in the amount of 25,610,038), with exercise prices ranging from $0.15 to $0.29 per share. To the extent the shares of common stock are issued, options and warrants are exercised, or promissory notes are converted, holders of our common stock will experience dilution. In addition, in the event of any future financing of equity securities or securities convertible into or exchangeable for, common stock, holders of our common stock may experience dilution. Moreover, the above-mentioned warrants to purchase our common stock are subject to “full ratchet” anti-dilution protection upon certain equity issuances below $0.15 per share (as may be further adjusted).

Shares eligible for future sale may adversely affect the market.

Sales of a significant number of shares of our common stock in the public market could harm the market price of our common stock. This prospectus covers 25,560,000 shares of common stock issuable upon exercise of our outstanding warrants, which represents approximately 6.0% of our outstanding shares of our common stock as of June 20, 2011 on a fully diluted basis. As additional shares of our common stock become available for resale in the public market pursuant to this offering, and otherwise, the supply of our common stock will increase, which could decrease its price. Some or all of the shares of common stock may be offered from time to time in the open market pursuant to Rule 144, and these sales may have a depressive effect on the market for our shares of common stock. In general, under Rule 144 as currently in effect, a non-affiliate of ours who has beneficially owned shares of our common stock for at least six months is entitled to sell his or her shares without any volume limitations, and an affiliate of ours can sell such number of shares within any three-month period as does not exceed the greater of 1% of the number of shares of our common stock then outstanding, which equaled approximately 2,300,835 shares as of June 20, 2011, or the average weekly trading volume of our common stock on the OTC Bulletin Board during the four calendar weeks preceding the filing of a notice on Form 144 with respect to that sale. Sales under Rule 144 by our affiliates are also subject to manner-of-sale provisions, notice requirements and the availability of current public information about us.

We are able to issue shares of preferred stock with rights superior to those of holders of our common stock. Such issuances can dilute the tangible net book value of shares of our common stock.

Our Amended and Restated Certification of Incorporation provides for the authorization of 5,000,000 shares of “blank check” preferred stock. Pursuant to our Amended and Restated Certificate of Incorporation, our board of directors is authorized to issue such “blank check” preferred stock with rights that are superior to the rights of stockholders of our common stock, at a purchase price then approved by our board of directors, which purchase price may be substantially lower than the market price of shares of our common stock, without stockholder approval. Such issuances can dilute the tangible net book value of shares of our common stock.

We do not intend to pay cash dividends.

We have not declared or paid any cash dividends on our common stock, and we do not anticipate declaring or paying cash dividends for the foreseeable future. Any future determination as to the payment of cash dividends on our common stock will be at our board of directors’ discretion and will depend on our financial condition, operating results, capital requirements and other factors that our board of directors considers to be relevant.

These forward-looking statements are made only as of the date of this prospectus. Except for our ongoing obligation to disclose material information as required by federal securities laws, we do not intend to update you concerning any future revisions to any forward-looking statements to reflect events or circumstances occurring after the date of this prospectus.

USE OF PROCEEDS

We will not receive any proceeds from the resale of the shares of common stock offered by the selling stockholder as all of such proceeds will be paid to the selling stockholder. Furthermore, we will not receive cash proceeds from the exercise of the warrants held by the affiliate of Optimus to the extent they are (i) exercised by a promissory note, as permitted by the terms of such warrants, or (ii) exercised pursuant to cashless exercise provisions contained therein, if then-permitted by the terms of the such warrant. No assurance can be given, however, as to when, if ever, any or all of such warrants will be exercised.

MARKET PRICE OF AND DIVIDENDS ON OUR COMMON STOCK

AND RELATED STOCKHOLDER MATTERS

Since July 28, 2005, our common stock has been quoted on the OTC Bulletin Board under the symbol ADXS.OB. The following table shows, for the periods indicated, the high and low bid prices per share of our common stock as reported by the OTC Bulletin Board. These bid prices represent prices quoted by broker-dealers on the OTC Bulletin Board. The quotations reflect inter-dealer prices, without retail mark-up, mark-down or commissions, and may not represent actual transactions.

	Fiscal 2011						Fiscal 2010				Fiscal 2009

(1)

From March 1, 2011 through April 1, 2011, our common stock was traded on the OTCQB Market place, a new market for OTC-traded companies that are registered and current in their reporting obligations to the SEC or a U.S. banking or insurance regulator.

(2)

Through June 20, 2011.

As of June 20, 2011, there were approximately 87 stockholders of record. Because shares of our common stock are held by depositaries, brokers and other nominees, the number of beneficial holders of our shares is substantially larger than the number of stockholders of record. Based on information available to us, we believe there are approximately 3,500 beneficial owners of our shares of our common stock in addition to the stockholders of record. On June 20, 2011, the last reported sale price per share for our common stock as reported by the OTC Bulletin Board was $0.149.

We have not declared or paid any cash dividends on our common stock, and we do not anticipate declaring or paying cash dividends for the foreseeable future. We are not subject to any legal restrictions respecting the payment of dividends, except that we may not pay dividends if the payment would render us insolvent. Any future determination as to the payment of cash dividends on our common stock will be at our board of directors’ discretion and will depend on our financial condition, operating results, capital requirements and other factors that our board of directors considers to be relevant.

Holders of Series B preferred stock will be entitled to receive dividends, which will accrue in shares of Series B preferred stock on an annual basis at a rate equal to 10% per annum from the issuance date. Accrued dividends will be payable upon redemption of the Series B preferred stock or upon the liquidation, dissolution or winding up of our company. The Series B preferred stock ranks, with respect to dividend rights and rights upon liquidation:

senior to our common stock and any other class or series of preferred stock (other than Series A preferred stock or any class or series of preferred stock that we intend to cause to be listed for trading or quoted on Nasdaq, NYSE Amex or the New York Stock Exchange);

pari passu with any outstanding shares of our Series A preferred stock (none of which are issued and outstanding as of the date hereof); and

junior to all of our existing and future indebtedness and any class or series of preferred stock that we intend to cause to be listed for trading or quoted on Nasdaq, NYSE Amex or the New York Stock Exchange.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis of Financial Conditions and Results of Operations and other portions of this prospectus contain forward-looking information that involves risks and uncertainties. Our actual results could differ materially from those anticipated by the forward-looking information. Factors that may cause such differences include, but are not limited to, availability and cost of financial resources, product demand, market acceptance and other factors discussed in this prospectus under the heading “Risk Factors”. This Management’s Discussion and Analysis of Financial Conditions and Results of Operations should be read in conjunction with our financial statements and the related notes included elsewhere in this prospectus.

Overview

Advaxis is a development stage biotechnology company with the intent to develop safe and effective cancer vaccines that utilize multiple mechanisms of immunity. We are developing a live Listeria vaccine technology under license from Penn which can be engineered to secrete a variety of different protein sequences containing tumor-specific antigens leading to the development of a variety of different products. We believe this vaccine technology is capable of stimulating the body’s immune system to process and recognize the antigen that has a therapeutic effect upon cancer. We believe this to be a broadly enabling platform technology that can be applied to the treatment of many types of cancers, infectious diseases and auto-immune disorders.

The discoveries that underlie this innovative technology are based upon the work of Yvonne Paterson, Ph.D., Professor of Microbiology at Penn. This technology involves the creation of genetically engineered Listeria that stimulate the innate immune system and induce an antigen-specific immune response involving both arms of the adaptive immune system. In addition, this technology supports, among other things, the immune response by altering tumors to make them more susceptible to immune attack, stimulating the development of specific blood cells that underlie a strong therapeutic immune response.

We have no customers. Since our inception in 2002, we have focused our development efforts upon understanding our technology and establishing a product development pipeline that incorporates this technology in the therapeutic cancer vaccines area targeting cervical, head and neck, prostate, breast, and a pre cancerous indication of CIN. Although no products have been commercialized to date, research and development and investment continues to be placed behind the pipeline and the advancement of this technology. Pipeline development and the further exploration of the technology for advancement entail risk and expense. We anticipate that our ongoing operational costs will increase significantly when we begin several of our clinical trials.

The following factors, among others, could cause actual results to differ from those indicated in the above forward-looking statements: increased length and scope of our clinical trials, failure to recruit patients, increased costs related to intellectual property related expenses, increased cost of manufacturing and higher consulting costs. These factors or additional risks and uncertainties not known to us or that we currently deem immaterial may impair business operations and may cause our actual results to differ materially from any forward-looking statement.

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements.

We expect our future sources of liquidity to be primarily debt and equity capital raised from investors, as well as licensing fees and milestone payments in the event we enter into licensing agreements with third parties, and research collaboration fees in the event we enter into research collaborations with third parties. In August 2009, we received an NIH grant for $210,739 for the development of a dual vector capable of attacking two immunologic targets simultaneously. In October 2010, we received notice that the company was awarded an IRS grant under the Qualified Therapeutic Discovery Program for approximately $245,000. This amount was included in grant revenue for the year ending October 31, 2010. We received the funds in November 2010.

On February 4, 2011 we received $379,742 from the New Jersey Economic Development Authority. Under the State of New Jersey NOL Transfer Program for small business we received this cash amount from the sale of our State Net Operating Losses through December 31, 2009. We plan to sell our Net Operating Losses for the 2010 fiscal year under the same State of New Jersey Program for small business.

If additional capital were raised through the sale of equity or convertible debt securities, the issuance of such securities would result in additional dilution to our existing stockholders. If we fail to raise a significant amount of capital, we may need to significantly curtail operations or cease operations in the near future. Any sale of our common stock or issuance of rights to acquire our common stock below $0.15 per share (as may be further adjusted) will trigger a significant dilution due to the anti-dilution protection provisions in certain of our outstanding warrants and debt instruments.

Plan of Operations

If we are successful in our financing plans we intend to use the majority of the proceeds to complete our two Phase II trials of ADXS11-001, our initial Listeria construct targeting diseases caused by the Human Papilloma Virus, which we refer to as HPV. One trial is a 120 patient U.S. study in CIN, and the other trial is a 110 patient Indian study in highly advanced cervical cancer. We also anticipate using the funds to further our preclinical and clinical, research and development efforts in developing product candidates in prostate cancer, breast and brain cancer and for general and administrative activities.

During the next 24 months, our strategic focus will be to achieve the following goals and objectives:

Complete our two Phase II clinical studies of ADXS11-001 in the therapeutic treatment of CIN and late-stage cervical cancer;

Begin an additional Phase II clinical trial of our ADXS11-001 candidate in the treatment of advanced cervical cancer with the Gynecologic Oncology Group, which we refer to as the GOG, largely underwritten by the NCI;

Continue to focus on our collaboration with the CRUK to carry out our Phase I/II clinical trial of our ADXS11-001 candidate in the treatment of head and neck cancer entirely underwritten by the CRUK;

Continue to support our Collaborative Research and Development Agreement with the U.S. Department of Homeland Security to develop vaccines for the protection of our food supply;

Continue to execute our Canine Osteosarcoma Study with Penn with relevance to human adolescents;

To support our new Collaborative Research and Development Agreement with the NCI to understand the mechanisms of action of attenuated Listeria vaccines, to develop new vaccines, and to advance them to clinical testing;

Continue to further our structured collaboration with the University of British Columbia on innovative uses of Listeria constructs in infectious disease, parasitical disease and neonatal immunity;

Continue to develop strategic and development collaborations with academic laboratories and potential commercial partners;

Continue the development work necessary to bring ADXS31-142 in the therapeutic treatment of prostate cancer into clinical trials, and initiate that trial provided that funding is available;

Continue the development work necessary to bring ADXS31-164 in the therapeutic treatment of breast, brain and other cancers into clinical trials, and initiate that trial when and if funding is available; and

Continue the preclinical development of other product candidates, as well as continue research to expand our technology platform.

Our projected annual staff, overhead, laboratory and nonclinical expenses are estimated to be approximately $4.1 million starting in fiscal year beginning November 1, 2010. The cost of our Phase II clinical studies in therapeutic treatment of CIN and late stage cervical cancer is estimated to be approximately $11.2 million over the estimated 30 month period of the trial. While approximately $4 million has already been paid towards these costs, we must raise additional funds in order to complete the Phase II trials. If we can raise additional funds we intend to commence the clinical work in prostate cancer by late 2011 and breast and brain cancer by late 2011. The timing and estimated costs of these projects are difficult to predict.

If the clinical progress continues to be successful and the value of our company increases, we may attempt to accelerate the timing of the required financing and, conversely, if the trial or trials are not successful we may slow our spending and defer the timing of additional financing. While we will attempt to attract a corporate partnership and grants, we have not assumed the receipt of any additional financial resources in our cash planning.

We anticipate that our research and development expenses will increase significantly as a result of our expanded development and commercialization efforts related to clinical trials, product development, and development of strategic and other relationships required ultimately for the licensing, manufacture and distribution of our product candidates. We regard three of our product candidates as major research and development projects. The timing, costs and uncertainties of those projects are as follows:

ADXS11-001 - Phase II CIN Trial Summary Information (U.S.: target enrollment: 120 Patients)

Cost incurred through April 30, 2011: approximately $3.0 million.

Estimated future clinical costs: approximately $4.5 million.

Anticipated Timing: commenced in March 2010 (with patient dosing having commenced in June 2010); reporting of low dose portion in late 2011, completion August 2012 or beyond.

Uncertainties:

The FDA (or relevant foreign regulatory authority) may place the project on clinical hold or stop the project;

One or more serious adverse events in otherwise healthy patients enrolled in the trial;

Difficulty in recruiting patients;

Delays in the program;

Material cash flows; and

Anticipated Timing: Unknown at this stage and dependent upon successful trials, adequate fund raising, entering a licensing deal or pursuant to a marketing collaboration subject to regulatory approval to market and sell the product.

ADXS11-001 - Phase II Cervical Cancer Trial Summary Information (India: target enrollment: 110 Patients)

Results of Operations

Three months ended April 30, 2011 compared to the three months ended April 30, 2010

Revenue

We did not record any revenue for the three months ended April 30, 2011. For the same period a year ago, revenue increased by approximately $87,000, representing grant revenue.

Research and Development Expenses

Research and development expenses increased by approximately $1,362,000 to approximately $2,447,000 for the three months ended April 30, 2011 as compared with approximately $1,085,000 for the same period a year ago principally attributable to clinical trial expenses increasing significantly resulting from the continuation of our clinical trials in the United States and India, which were initiated during the first fiscal quarter of 2010. In addition, overall compensation expense was higher in the current period resulting from additional employees, increased stock-based compensation and increases in salaries to existing employees.

We anticipate continued increases in R&D expenses as a result of expanded development efforts primarily related to clinical trials and product development. In addition, expenses will be incurred in the development of strategic and other relationships required to license, manufacture and distribute our product candidates.

General and Administrative Expenses

General and administrative expenses increased by approximately $182,000 or 23%, to approximately $962,000 for the three months ended April 30, 2011 as compared with approximately $779,000 for the same period a year ago. This was the result of higher legal, professional and other consulting fees in the current period as compared with the same period a year ago due to the Company’s capital raising efforts. Overall compensation expense was lower in the current period resulting from higher salary costs in the prior period that did not repeat in the current period. Additionally, office and related expenses increased in the current period due to the relocation of the Company’s operations to Princeton, NJ in April 2011 but were offset somewhat by lower travel expenses.

Interest Expense

For the three months ended April 30, 2011, interest expense decreased to approximately $419,000 from approximately $1,647,000 primarily resulting from the conversion, repayment of and maturation of Bridge Notes from the second fiscal quarter of 2010 through the current quarter ending April 30, 2011.

Other Expense/ Income

Interest income increased to approximately $48,000 as compared to approximately $15,000 in the same period a year ago as a result of interest earned on additional Optimus notes receivable. These notes are classified in the equity section of the balance sheet as a stock subscription receivable. Other expense increased to approximately $28,000 as compared to $0 in the same period a year ago as a result of changes in foreign exchange rates relating to transactions with certain vendors.

Gain on Note Retirement

For the three months ended April 30, 2011, income from the gain on note retirement decreased to approximately $6,000 from $64,354 in the same period a year ago due to repayments of bridge notes in the current period compared with the same period a year ago.

Changes in Fair Values

The change in fair value of the common stock warrant liability and embedded derivative liability for both periods was approximately $5.8 million resulting from increased share prices. . In the current period, the Company’s the share price increased from $0.15 at January 31, 2011 to $0.21 at April 30, 2011. During the period a year ago, the Company’s share price increased from $0.135 at January 31, 2010 to $0.21 at April 30, 2010.

Potential future increases or decreases in our stock price will result in increased or decreased warrant and embedded derivative liabilities, respectively, on our balance sheet and therefore increased or decreased expenses being recognized in our statement of operations in future periods.

Results of Operations for the Six Months Ended April 30, 2011 and 2010

Revenue

We did not record any revenue for the six months ended April 30, 2011. For the same period a year ago, revenue increased by approximately $87,000, representing grant revenue.

Research and Development Expenses

Research and development expenses increased by approximately $2,352,000 to approximately $4,434,000 for the six months ended April 30, 2011 as compared with approximately $2,082,000 for the same period a year ago. This is principally attributable to clinical trial expenses increasing significantly resulting from the continuation of our clinical trials in the United States and India which were initiated during the first fiscal quarter of 2010. In addition, overall compensation expense was higher in the current period resulting from additional employees, increased stock-based compensation and increases in salaries to existing employees. We anticipate continued increases in R&D expenses as a result of expanded development efforts primarily related to clinical trials and product development. In addition, expenses will be incurred in the development of strategic and other relationships required to license, manufacture and distribute our product candidates.

General and Administrative Expenses

General and administrative expenses increased by approximately $576,000 or 42%, to approximately $1,944,000 for the six months ended April 30, 2011 as compared with approximately $1,368,000 for the same period a year ago, primarily as a result of the following: Overall compensation expense was higher in the current period resulting from additional employees, increases in salaries to existing employees and higher stock based compensation. Legal, professional and other consulting fees also increased in the current period, along with travel and entertainment expenses, due to the Company’s capital raising efforts. Additionally, office and related expenses grew in the current period due to the relocation of the Company’s corporate and scientific operations to Princeton, NJ in April 2011. Lastly, the Company experienced an increase in non-cash expenses: amortization expense increased in the current period due to additions to our patent portfolio since the same period last year; warrant expense increased in the current period due to the issuance of additional warrants to a vendor and an investor.

Interest Expense

For the six months ended April 30, 2011, interest expense decreased to approximately $951,000 from approximately $3,313,000 primarily resulting from the conversion, payoff and maturation of Bridge Notes from the second fiscal quarter of 2010 through the current quarter ending April 30, 2011.

Other Expense/ Income

Interest income increased to approximately $102,000 as compared to approximately $17,000 in the same period a year ago as a result of interest earned on additional Optimus transaction notes receivable. These notes are classified in the equity section of the balance sheet as a stock subscription receivable.

For the six months ended April 30, 2011, other expense increased approximately $44,000 as a result of changes in foreign exchange rates relating to transactions with certain vendors.

Gain on Note Retirement

For the six months ended April 30, 2011, income from the gain on note retirement decreased to approximately $6,000 from $64,354 inthe same period a year ago due to less repayments of bridge notes in the current period compared with the same period a year ago.

Changes in Fair Values

The change in fair value of the common stock warrant liability and embedded derivative liability decreased to an expense of approximately $1.99 million for the six months ending April 30, 2011 compared to expense of approximately $6.88 million in the same period a year ago. During the current period, the Company recorded expense of $5.83 million due to the share price increasing from $0.15 at January 31, 2011 to $0.21 at April 30, 2011, resulting in substantially all of the expense that was recorded to the change in fair value account. This increase in expense was partially offset by income of $3.84 million being recorded to the change in fair value account due to the following: a decrease in the volatility of the underlying stock price decreased the liability associated with substantially all warrants, resulting in most of the income that was recorded to the change in fair value account. In addition, the share price declined from approximately $0.15 at November 1, 2010 to $0.147 at January 31, 2011, resulting in some of the income that was recorded to the change in fair value account. In total, the Company recorded net expense of $1.99 million for the six months ended April 30, 2010.

During the period a year ago, the Company recorded expense of $6.88 million as the share price increased from approximately $0.13 at November 1, 2009 to $0.21 at April 30, 2010, resulting in most of the expense that was recorded to the change in fair value account. Secondly, the exercise price of substantially all warrants decreased from $0.20 to $0.17, as a result of the January 11, 2010 trigger of antidilution provisions in the warrant agreements, effectively increasing the liability associated with substantially all warrants, resulting in some of the expense that was recorded to the change in fair value account.

Income Tax Benefit

In the six months ended April 30, 2011 income tax benefit increased by $100,494, to $379,472 in income, due to a gain recorded from the receipt of a Net Operating Loss (“NOL”) tax credit from the State of New Jersey tax program compared to the $278,978 in NOL tax credits received from the State of New Jersey tax program in the six months ended April 30, 2010.

Fiscal Year 2010 Compared to Fiscal Year 2009

Revenue

Revenue increased by approximately $478,791 to $508,481 for the year ended October 31, 2010, as compared with $29,690 for the same period a year ago, as a result of grant revenue received by us.

Research and Development Expenses

Research and development expenses increased by approximately $2,589,000 to $4,904,298 for the year ended October 31, 2010 as compared with $2,315,557 for the same period a year ago. This increase is almost entirely attributable to clinical trial expenses, which increased significantly in the current fiscal year due to our clinical trial activity in the United States and India, initiated during the first fiscal quarter of 2010.

We anticipate a significant increase in research and development expenses as a result of expanded development and commercialization efforts primarily related to clinical trials and product development. In addition, expenses will be incurred in the development of strategic and other relationships required to license manufacture and distribute our product candidates.

General and Administrative Expenses

General and administrative expenses increased by approximately $829,000 or 22%, to $3,530,198 for the year ended October 31, 2010 as compared with $2,701,133 for the same period a year ago. This is primarily attributable to overall compensation expense being higher in the current fiscal year resulting from additional employees, costs related to a former employee and stock-based non cash compensation resulting from the issuance of 750,000 shares of our common stock pursuant to an executive’s employment agreement with us. Overall professional fees also increased in the current year as a result of higher recruiting, legal and accounting fees in fiscal 2010 compared with a year ago. In addition, consulting and travel fees increased in the current fiscal year primarily due to increased efforts by us to present our scientific and business plans. We also recognized approximately $206,000 in non-cash warrant expense, as compared to $0 in the prior fiscal year, as a result of additional warrants that were issued to senior and junior bridge note holders in September 2010. All of the above increases were somewhat offset by higher offering expenses in fiscal 2009 that did not repeat in the current fiscal year.

Interest Expense/Income

In the year ended October 31, 2010, net interest expense increased by approximately $3 million to $3,814,863 compared to $851,008 for the same period a year ago, primarily because in the fiscal year ended October 31, 2010 we recognized both (i) twelve months of interest expense for notes sold during the third and fourth fiscal quarters of 2009 and (ii) partial-year interest expense for notes sold in the fiscal year ended October 31, 2010 whereas in the fiscal year ended October 31, 2009 we only recognized partial-year interest expense for notes sold during the third and fourth fiscal quarters of 2009. Additionally, the debt discount, warrant liabilities and embedded derivatives related to the notes are recorded as a liability on the balance sheet and are amortized to interest expense over the life of the notes. Interest income earned during the year ended October 31, 2010 of approximately $80,000 was the result of interest earned from the Optimus notes receivable. These notes are classified in the equity section of the balance sheet as a stock subscription receivable.

Changes in Fair Values

The change in fair value of the common stock warrant liability and embedded derivative liability increased income by approximately $446,000 for the year ended October 31, 2010 compared to approximately $5.8 million the same period a year ago. During the fiscal year ended October 31, 2009 we recorded income due to changes in management’s assumptions used to calculate the fair value of our warrant and embedded derivative liability. This change in assumption substantially decreased both the number of warrants and related BSM values used in calculating the warrant liability, therefore decreasing the overall warrant and embedded derivative liability at October 31, 2009. For the first nine months of the fiscal year ended October 31, 2010, the BSM values associated with these warrants and embedded derivatives increased resulting from the increase in the price of our common stock, from $0.135 at October 31, 2009 to $0.17 at July 31, 2010. However, from July 31 to October 31, 2010, the number of outstanding warrants increased due to a decrease in their exercise price and the BSM values decreased due to a decline in the price of our common stock, resulting in our recording income for the full year.

Potential future increases or decreases in our stock price will result in increased or decreased warrant and embedded derivative liabilities, respectively, on our balance sheet and therefore increased expenses being recognized in our statement of operations in future periods.

For the fiscal year ended October 31, 2010, we recorded income of approximately $124,000 on the non-cash gain on the early retirement of certain senior and junior bridge notes.

Income Tax Benefit

For the fiscal year ended October 31, 2010, other income decreased by approximately $643,000, to approximately $279,000 as compared to approximately $922,000 a year ago, primarily due to the fiscal 2009 period NOL being the first time we received funds from the program and so the award covered all prior fiscal years’ NOLs from our inception whereas the award for the fiscal year ended October 31, 2010 covered only the current fiscal year’s NOL and prior two fiscal years of the research tax credit.

Liquidity and Capital Resources

Since our inception through April 30, 2011, the Company has reported accumulated net losses of approximately $37.5 million and recurring negative cash flows from operations. We anticipate that we will continue to generate significant losses from operations for the foreseeable future.

Cash used in operating activities, for the six months ending April 30, 2011, was approximately $3.2 million, primarily as a result of the following: increased R&D spending on clinical trials and higher general and administrative spending.

Cash used in investing activities, for the six months ending April 30, 2011, was approximately $191,000 resulting from legal cost spending in support of our intangible assets (patents) and costs paid to the University of Pennsylvania for patent research.

Cash provided by financing activities, for the six months ending April 30, 2011, was approximately $4.2 million, primarily as a result of the sale of preferred stock to Optimus in addition to proceeds received from the sale of junior unsecured convertible notes.

Our limited capital resources and operations to date have been funded primarily with the proceeds from public, private equity and debt financings, NOL tax sales and income earned on investments and grants. We have sustained losses from operations in each fiscal year since our inception, and we expect losses to continue for the indefinite future, due to the substantial investment in research and development. As of October 31, 2010 and April 30, 2011, we had an accumulated deficit of $27,416,000 and $36,294,750, respectively and shareholders’ deficiency of $14,802,631 and $22,238,081, respectively.

During May 2011 the Company sold $7.1 million of Convertible promissory notes for a net purchase price of $6.0 million and received cash from warrant exercises in the amount of approximately $350,000. This cash was used to reduce overdue payables and finance day to day operations.

Based on our available cash of approximately $3,400,000 on June 3, 2011, we do not have adequate cash on hand to cover our anticipated expenses for the next 12 months. If we fail to raise a significant amount of capital, we may need to significantly curtail or cease operations in the near future. These conditions have caused our auditors to raise substantial doubt about our ability to continue as a going concern. Consequently, the audit report prepared by our independent public accounting firm relating to our financial statements for the year ended October 31, 2010 included a going concern explanatory paragraph.

Our business will require substantial additional investment that we have not yet secured, and our failure to raise capital and/or pursue partnering opportunities will materially adversely affect our business, financial condition and results of operations. We expect to spend substantial additional sums on the continued administration and research and development of proprietary products and technologies, including conducting clinical trials for our product candidates, with no certainty that our products will become commercially viable or profitable as a result of these expenditures. Further, we will not have sufficient resources to develop fully any new products or technologies unless we are able to raise substantial additional financing on acceptable terms or secure funds from new partners. We cannot be assured that financing will be available at all. Any additional investments or resources required would be approached, to the extent appropriate in the circumstances, in an incremental fashion to attempt to cause minimal disruption or dilution. Any additional capital raised through the sale of equity or convertible debt securities will result in dilution to our existing stockholders. However, no assurances can be given that we will be able to achieve these goals or that we will be able to continue as a going concern.

We are pursuing additional investments, grants, partnerships as well as collaborations and exploring other financing options, with the objective of minimizing dilution and disruption.

Pursuant to the Series B purchase agreement, as amended, Optimus has agreed to purchase, upon the terms and subject to the conditions set forth therein and described below, up to $7.5 million of our newly authorized, non-convertible, redeemable Series B preferred stock at a price of $10,000 per share, of which $2.84 million of Series B preferred stock remains available for purchase. Under the terms of the Series B purchase agreement, as amended, we may from time to time until July 19, 2013, present Optimus with a notice to purchase a specified amount of Series B preferred stock. Subject to satisfaction of certain closing conditions, Optimus is obligated to purchase such shares of Series B preferred stock on the 10th trading day after the date of the notice. We will determine, in our sole discretion, the timing and amount of Series B preferred stock to be purchased by Optimus, and may sell such shares in multiple tranches. Optimus will not be obligated to purchase the Series B preferred stock upon our notice (i) in the event the closing price of our common stock during the nine trading days following delivery of our notice falls below 75% of the closing price on the trading day prior to the date such notice is delivered to Optimus or (ii) to the extent such purchase would result in Optimus and its affiliates beneficially owning more than 9.99% of our outstanding common stock.

As of April 30, 2011, we had issued and sold 466 shares of Series B preferred stock to Optimus pursuant to the terms of the Series B purchase agreement, as amended. We received net proceeds of approximately $4.19 million from this transaction. The aggregate purchase price for the Series B preferred stock was $4.66 million. As of April 30, 2011, under the terms of the Series B purchase agreement, as amended, Optimus remained obligated, from time to time until July 19, 2013, to purchase up to an additional 284 shares of Series B preferred stock at a purchase price of $10,000 per share upon notice from us to Optimus, if certain conditions set forth in the Series B purchase agreement, as amended, are satisfied.

On December 30, 2010, immediately following the closing of the sale of 72 shares of Series B preferred stock to Optimus pursuant to the terms of the Series B purchase agreement, we redeemed 226 shares of Series B Preferred Stock held by Optimus for an aggregate redemption price of $3,141,004 consisting of (i) cash in an amount of $76,622 and (ii) the cancellation of certain promissory notes issued by an affiliate of Optimus to us in the aggregate amount of $3,064,382. The Company redeemed the shares of Series B Preferred Stock , at a price per share equal to 136% of the Liquidation Value (defined as the original price per share plus all accrued dividends thereon) since the redemption was prior to the first anniversary of the issuance date, as stated in the Series B Preferred Stock Agreement.

In connection with the Series B preferred equity financing, an affiliate of Optimus was granted on July 19, 2010 a warrant to purchase up to 40,500,000 shares of our common stock at an exercise price of $0.25 to be adjusted in connection with the draw down of each tranche. As permitted by the terms of such warrant, the aggregate exercise price of $6,291,000 received by us as of April 30, 2011 is payable pursuant to four year full recourse promissory notes each bearing interest at the rate of 2% per year.

On September 24, 2009, we entered into a preferred stock purchase agreement with Optimus, which we refer to as the Series A purchase agreement, pursuant to which Optimus agreed to purchase, upon the terms and subject to the conditions set forth therein, up to $5.0 million of Series A preferred stock at a price of $10,000 per share. As of May 13, 2010, all 500 shares of Series A preferred stock were issued and sold to Optimus. On July 19, 2010, we issued 500 shares of Series B preferred stock to Optimus, which we refer to as the Series B exchange shares, in exchange for the 500 shares of Series A preferred stock so that all shares of our preferred stock held or subsequently purchased by Optimus under the Series B purchase agreement, as amended, would be redeemable upon substantially identical terms. In connection with the Series A preferred equity financing, an affiliate of Optimus was granted on September 24, 2009 a warrant to purchase up to 33,750,000 shares of our common stock at an exercise price of $0.20 to be adjusted in connection with the draw down of each tranche. On January 11, 2010, the draw down date of the first tranche, the affiliate of Optimus exercised a portion of the warrant to purchase 11,563,000 shares of common stock at an adjusted exercise price of $0.17 per share. On March 29, 2010, the draw down date of the second tranche, the affiliate of Optimus exercised a portion of the warrant to purchase 14,580,000 shares of common stock at an exercise price of $0.20 per share. On May 13, 2010, the draw down date of the final tranche, the affiliate of Optimus exercised the remainder of the warrant to purchase 7,607,000 shares of common stock at an adjusted exercise price of $0.18 per share. In each case, we agreed with Optimus and its affiliate to waive certain terms and conditions in the Series A purchase agreement and the warrant in order to permit the affiliate of Optimus to exercise the warrant at such adjusted exercise prices prior to the closing of the purchase of the Series A preferred stock and acquire beneficial ownership of more than 4.99% of our common stock on the date of each exercise. As permitted by the terms of such warrant, the aggregate exercise prices of $1,965,710, $2,916,000 and $1,369,260 for the first tranche, second tranche and final tranche, respectively, received by us is payable pursuant to three separate four year full recourse promissory notes each bearing interest at the rate of 2% per year. In addition, in connection with the draw down of the final tranche, we issued an additional warrant to an affiliate of Optimus to purchase up to 2,818,000 shares of common stock at an exercise price of $0.18 per share, subject to customary anti-dilution adjustments (the exercise price of which may also be paid at the option of the affiliate of Optimus in cash or by its issuance of a promissory note on the same terms as the foregoing promissory notes). The foregoing promissory notes are not due or payable at any time that (a) we are in default of under the Series A preferred stock purchase agreement, any loan agreement or other material agreement or (b) there are any Series B exchange shares issued or outstanding.

On June 18, 2009, we completed the senior bridge financing. The senior bridge financing was a private placement with certain accredited investors pursuant to which we issued (i) senior bridge notes in the aggregate principal face amount of $1,131,353, for an aggregate net purchase price of $961,650 and (ii) senior bridge warrants to purchase 2,404,125 shares of our common stock at an exercise price of $0.20 per share (prior to giving effect to anti-dilution adjustments which have subsequently reduced the exercise price to $0.15 per share), subject to adjustments upon the occurrence of certain events. Each of the senior bridge notes were issued with an original issue discount of 15% and were convertible into shares of our common stock in certain circumstances. The senior bridge notes had an initial maturity date of December 31, 2009. During January and February 2010, we repaid $834,852 of the $1,131,353 in face value of our senior bridge notes. In addition, holders of the remaining $296,501 of our senior bridge notes agreed to extend the maturity dates from December 31, 2009 to periods into February and March 2010. We have agreed to issue additional consideration, including warrants to senior bridge note holders, all of whom agreed to extend the maturity period beyond December 31, 2009. As of April 30, 2011, we had one outstanding senior bridge note with approximately $89,000 in principal value and $26,471 in accrued interest remaining. In May 2011, we received a notice of intent to convert the principal and accrued interest on the outstanding senior bridge note into shares of our common stock.

From November 1, 2009 through January 31, 2011, we issued to certain accredited investors (i) junior bridge notes in the aggregate principal face amount of approximately $2,860,000 for an aggregate net purchase price of approximately $2,490,000 and (ii) warrants to purchase 8,816,745 shares of our common stock (including additional warrants issued as a result of anti-dilution provisions triggered in January 2010 and/or note exchanges), which we refer to as junior bridge warrants, at original exercise prices ranging from $0.15 to $0.25 per share, subject to adjustments upon the occurrence of certain events. These junior bridge notes were issued with original issue discounts ranging from 5% to 18% and are convertible into shares of our common stock. These junior bridge notes mature on or before May 31, 2011.

As a result of anti-dilution provisions in the senior bridge warrants, certain of the junior bridge warrants and the warrants issued in connection with the equity financings completed in October 2007 being triggered by the tranche take down under the Series B purchase agreement in September 2010, we agreed to issue an additional 616,136 warrants to some of the junior bridge note investors at an exercise price of $0.15 per share and agreed to reduce the exercise price of the warrants held by such senior and junior bridge note investors to $0.15 per share (formerly ranging from $0.17 to $0.25 per share).

From November 1, 2009 through April 30, 2011, we repaid a total of approximately $1,730,000 in principal value of junior bridge notes and converted $2,420,000 in principal value of junior bridge notes into 14,237,489 shares of our common stock. At April 30, 2011, approximately $2,216,000 in principal value of junior bridge notes remained outstanding and is classified as a current liability on the balance sheet. The indebtedness represented by these junior bridge notes is expressly subordinate to our currently outstanding senior secured indebtedness (approximately $89,000 of senior bridge notes at April 30, 2011).

As a result of anti-dilution protection provisions contained in certain of our outstanding warrants, we (i) reduced the exercise price from $0.20 to $0.17 per share in January 2010 and further reduced the exercise price from $0.17 to $0.15 per share in September 2010 with respect to substantially all the warrants to purchase shares of our common stock and (ii) correspondingly adjusted the amount of warrant shares issuable such that approximately 11.4 million additional warrant shares are issuable related to the January 2010 repricing and approximately 10.4 million additional warrant shares are issuable related to the September 2010 repricing. As of April 30, 2011, approximately 87.6 million warrant shares are currently exercisable at $0.15 per share.

On September 22, 2008 we entered into a note purchase agreement with our Chief Executive Officer, Thomas A. Moore, pursuant to which we agreed to sell to Mr. Moore, from time to time, Moore Notes, which we refer to as the Moore Agreement. The Moore Notes have been amended from time to time. During 2010, we agreed to amend the terms of the Moore Notes such that Mr. Moore may elect, at his option, to receive accumulated interest thereon (of which we paid $130,000 on March 17, 2010) and that we will begin to make installment payments on the outstanding principal beginning on April 15, 2010 (of which $250,000 was paid during the year ended October 31, 2010); provided, however, that the balance of the principal will be repaid in full as a result of either (i) consummation of our next equity financing resulting in gross proceeds to the company of at least $6.0 million or (ii) default by the company as defined under the terms of the Moore Agreement. Additionally, we agreed to retain $200,000 of the repayment amount for investment in our next equity financing (Mr. Moore exchanged debt with the principal amount of $200,000 into 1,176,471 shares of our common stock in May 2010).

In connection with a loan made by Mr. Moore to the company in the amount of $230,000, we agreed to amend and restate the terms of the Moore Notes on March 17, 2011 to increase the principal amount by $230,000. Under the terms of the amended and restated Moore Notes: (i) the maturity date is the earlier of (x) the date of consummation of an equity financing by us in an amount of $6.0 million or more and (y) the occurrence of any event of default as defined in the Moore Notes, (ii) Mr. Moore may elect, at his option, to receive accumulated interest thereon on or after April 15, 2011 (which we expect will amount to approximately $91,000), (iii) we will make monthly installment payments of $100,000 on the outstanding principal amount beginning on June 15, 2011, and (iv) we may retain, at the option of Mr. Moore, $200,000 of the repayment amount for investment in our next equity financing.

For the three months ending April 2011, Mr. Moore loaned the Company, in total, $295,000 under the terms of the amended and restated Moore Notes as described above.

The Moore Notes bear interest at a rate of 12% per annum and may be prepaid in whole or in part at our option without penalty at any time prior to maturity.

For the three months ending April 30, 2011, the Company did not make any interest or principal payments to Mr. Moore. As of April 30, 2011, the Company was not in default under the terms of the Moore Agreement. As of April 30, 2011, the Company owed Mr. Moore approximately $873,000 in principal and approximately $97,000 in accrued interest under the Moore Notes.

In October 2010, we received an IRS grant under the Qualified Therapeutic Discovery Program for approximately $245,000. We plan to sell our Net Operating Losses and research tax credits for the 2009 fiscal year under the same State of New Jersey NOL Transfer Program for small business.

Off-Balance Sheet Arrangements

As of April 30, 2011, we had no off-balance sheet arrangements, other than our lease for space. There were no changes in significant contractual obligations during the six months ended April 30, 2011.

Critical Accounting Estimates

The preparation of financial statements in accordance with GAAP accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts and related disclosures in the financial statements. Management considers an accounting estimate to be critical if:

It requires assumption to be made that were uncertain at the time the estimate was made, and

Changes in the estimate of difference estimates that could have been selected could have material impact in our results of operations or financial condition.

Actual results could differ from those estimates and the differences could be material. The most significant estimates impact the following transactions or account balances: stock compensation, liabilities, warrant valuation, impairment of intangibles, fixed assets and projected operating results.

Share-Based Payment. We record compensation expense associated with stock options in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, Stock Compensation (formerly, FASB Statement 123R). We adopted the modified prospective transition method provided under SFAS No. 123R. Under this transition method, compensation expense associated with stock options recognized in the first quarter of fiscal year 2007, and in subsequent quarters, includes expense related to the remaining unvested portion of all stock option awards granted prior to April 1, 2006, the estimated fair value of each option award granted was determined on the date of grant using the Black-Scholes option valuation model, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123.

We estimate the value of stock options awards on the date of grant using the Black-Scholes-Merton option-pricing model. The determination of the fair value of the share-based payment awards on the date of grant is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the term of the awards, expected term, risk-free interest rate, expected dividends and expected forfeiture rates. The forfeiture rate is estimated using historical option cancellation information, adjusted for anticipated changes in expected exercise and employment termination behavior. Our outstanding awards do not contain market or performance conditions; therefore we have elected to recognize share based employee compensation expense on a straight-line basis over the requisite service period.

If factors change and we employ different assumptions in the application of ASC 718 in future periods, the compensation expense that we record under ASC 718 relative to new grants may differ significantly from what we have recorded in the current period. There is a high degree of subjectivity involved when using option-pricing models to estimate share-based compensation under ASC 718. Consequently, there is a risk that our estimates of the fair values of our share-based compensation awards on the grant dates may bear little resemblance to the actual values realized upon the exercise, expiration, early termination or forfeiture of those share-based payments in the future. Employee stock options may expire worthless or otherwise result in zero intrinsic value as compared to the fair values originally estimated on the grant date and reported in our financial statements. Alternatively, value may be realized from these instruments that are significantly in excess of the fair values originally estimated on the grant date and reported in our financial statements.

Warrants.

Warrants were issued in connection with the equity financings completed in October 2007, the sale of preferred stock and the issuance of our senior and junior bridge notes. At April 30, 2011, we estimated the fair value of the outstanding instruments using the Black-Scholes valuation model, which takes into account a variety of factors, including historical stock price volatility, risk-free interest rates, remaining term and the closing price of our common stock. Changes in assumptions used to estimate the fair value of these derivative instruments could result in a material change in the fair value of the instruments. We believe the assumptions used to estimate the fair values of the warrants are reasonable.

As of April 30, 2011, we had outstanding warrants to purchase 117,140,234 shares of our common stock (adjusted for anti-dilution provisions to-date) including approximately 87.6 million warrants with an exercise price of $0.15 per share. These warrants include 25,610,038 warrants owned by Optimus as part of the Series B purchase agreement.

New Accounting Pronouncements

In April 2010, FASB issued Accounting Standards Update (ASU) 2010-17, Revenue Recognition—Milestone Method (Topic 605) - Milestone Method of Revenue Recognition - a consensus of the FASB Emerging Issues Task Force. This ASU provides guidance to vendors on the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. This guidance is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted.

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

DESCRIPTION OF BUSINESS

General

We are a development stage biotechnology company with the intent to develop safe and effective cancer vaccines that utilize multiple mechanisms of immunity. We are developing a live Listeria vaccine technology under license from Penn, which secretes a protein sequence containing a tumor-specific antigen. We believe this vaccine technology is capable of stimulating the body’s immune system to process and recognize the antigen as if it were foreign, generating an immune response able to attack the cancer. We believe this to be a broadly enabling platform technology that can be applied to the treatment of many types of cancers, infectious diseases and auto-immune disorders.

We have focused our initial development efforts upon therapeutic cancer vaccines targeting cervical cancer, its predecessor condition, CIN, head and neck cancer, breast cancer, prostate cancer, and other cancers. Our lead products in development are as follows:

Product	Indication	Stage
ADXS11-001	Cervical Cancer	Phase I Company sponsored & completed in 2007.

	Cervical Intraepithelial Neoplasia	Phase II Company sponsored study; commenced in March 2010 (with patient dosing having commenced in June 2010).

	Cervical Cancer	Phase II Company sponsored study initiated in November 2010 in India. 110 Patients with advanced cervical cancer.

	Cervical Cancer	Phase II The Gynecologic Oncology Group of the National Cancer Institute has agreed to conduct a study which we expect will commence in early 2011.

	Head & Neck Cancer	Phase I The Cancer Research UK (CRUK) is funding a study of up to 45 patients at 3 UK facilities that we expect will commence in early 2011.

ADXS31-142	Prostate Cancer	Phase I Company sponsored (timing to be determined).

ADXS31-164	Breast Cancer	Phase I Company sponsored (timing to be determined).

ADXS31-164	Canine Osteosarcoma	Phase I Company sponsored (timing to be determined).

To date, we have outsourced many functions of drug development including; manufacturing, and clinical trials management. Accordingly, the expenses of these outsourced services account for a significant amount of our accumulated loss. We cannot predict when, if ever, any of our product candidates will become commercially viable or approved by the FDA. We expect to spend substantial additional sums on the continued administration and research and development of proprietary products and technologies, including conducting clinical trials for our product candidates, with no certainty that our products will become commercially viable or profitable as a result of these expenditures.

Strategy

During the next 24 months, we will focus on developing sufficient human clinical data on ADXS11-001, our first Listeria construct, to demonstrate clinical effectiveness in cervical cancer and it’s medical predecessor condition, CIN. Beyond effectiveness specifically against HPV oncogenes, we also want to demonstrate more broadly that attenuated Listeria that secretes an antigen adjuvant fusion protein is an effective platform for multiple therapies against cancer and infectious disease. In the U.S., we have initiated a single blind, placebo controlled Phase II clinical trial of ADXS11-001 with three dosage arms in Cervical Intraepithelial Neoplasia (cervical dysplasia, CIN), a pre cancerous condition. In India, we have launched a 110 patient Phase II trial in advanced cervical cancer in women who have progressed after receiving cytotoxic therapy.

Within the next three months we will initiate in the U.S. another NCI-supported study in late stage cervical cancer, and a head and neck cancer study with CRUK in the United Kingdom, which we refer to as the U.K. We have signed an agreement to collaborate in a clinical trial with the Gynecologic Oncology Group (GOG), one of NIH’s clinical research groups, which will underwrite the cost and whose members will execute the trial. It is expected that this U.S. Phase II multi-center study will result in a cost avoidance benefit to us valued at between $7 million to $8 million in trial expenses. The CRUK initial study is expected to be worth between $2.5 and 3.5 million.

We have entered into a clinical trials agreement with the School of Veterinary Medicine at Penn to investigate the use of our compound ADXS31-164 for the treatment of osteosarcoma in dogs. This disease is the leading cancer killer of large dogs and is a model for the treatment of human osteosarcoma, the leading fatal bone cancer in adolescents.

We have also initiated production of two new human grade vaccines for which we expect to begin clinical development in 2011. Planning has begun for Phase I trials for ADXS31-142 for the treatment of prostate cancer, and ADXS31-164 for the treatment of breast, brain and other cancers.

Although we have been successful in obtaining clinical funding from the U.S. and the U.K., in order to implement our strategy, we will require substantial additional investment in the near future. Our failure to raise capital or pursue partnering opportunities will materially and adversely affect both our ability to commence or continue the clinical trials described above and our business, financial condition and results of operations, and could force us to significantly curtail or cease operations. Further, we will not have sufficient resources to develop fully any new products or technologies unless we are able to raise substantial additional financing over and above the preferred stock financing on acceptable terms or secure funds from new partners.

Given our expertise in genetically modifying Listeria to create vaccines for many different diseases, our longer term strategy will be to license the commercial development of ADXS11-001 for the indications of CIN, cervical and head and neck cancers, and other HPV related diseases. On a global basis, these indications are extremely large and will require one or more significant partners. We do not intend to engage in commercial development beyond Phase II without entering into one or more partnerships or a license agreement.

We intend to continue to devote a substantial portion of our resources to basic science and the continued pre-clinical development and optimization of our technology so as to develop it to its full potential and to find additional new drug candidates. These activities may require significant financial resources, as well as areas of expertise beyond those readily available. In order to provide additional resources and capital, we may enter into research, collaborative or commercial partnerships, joint ventures, or other arrangements with competitive or complementary companies, including major international pharmaceutical companies or universities.

Background

Cancer

Cancer is the second largest cause of death in the U.S., exceeded only by heart disease. The cost of treating cancer patients in 2008 was estimated to be $228.1 billion in healthcare costs and another $188 billion in indirect costs resulting from morbidity and lost productivity (source: Facts & Figures 2009, American Cancer Society). The American Cancer Society’s most recent estimates for newly diagnosed cervical cancer in the U.S. in 2010 was 12,200 and numbers for newly diagnosed CIN are approximately about 250,000 patients per year based on 3.5 million abnormal Pap smears (source: Jones HW, Cancer 1995:76:1914-18; Jones BA and Davey, Arch Pathol Lab Med 2000; 124:672-81). Overall predicted incidence and mortality rates for 2009 are set forth below:

Immune System and Normal Antigen Processing

People, are continually confronted with potentially infectious agents. The immune system has evolved multiple mechanisms to fight disease, including innate immunity, two forms of adaptive immunity humoral (antibody), and cellular immunity that mobilize the body’s natural defenses against these foreign agents to eliminate them.

Innate Immunity:

Innate immunity is the first step in the recognition of a foreign antigen. It is a non-specific protective response that also underlies the generation of an adaptive (antigen- specific) immune responses. It is characterized by the release of various soluble mediators of immune response such as cytokines, chemokines and other molecules.

Exogenous pathway of Adaptive Immunity (Class II pathway):

Proteins and foreign molecules ingested by Antigen Presenting Cells, or APCs, are broken down inside digestive vacuoles into small pieces, and the pieces are combined with proteins called Class 2 MHC (for Major Histocompatibility Complex) in a part of the cell called the endoplasmic reticulum. The MHC-peptide, termed and MHC-2 complex from the Class 2 (or exogenous) pathway, migrates to the cell surface where it interacts with certain classes of lymphocytes (CD4+) called helper T-cells that support the function of cytotoxic T-lymphocytes (killer T cells). This interaction renders CD4+ cells antigen specific, and they express their function whenever they encounter the antigen to which they’ve been activated. This system is called the exogenous pathway, since it is the prototypical response to an antigen from outside of the cell, like bacteria.

Endogenous pathway of Adaptive Immunity (Class I pathway):

The endogenous pathway provides immune protection against antigens created within the cytoplasm of the APC (as opposed exogenous molecules contained within he digestive phagosome). These intracellular antigens are typically broken down by within the cell and directed to the endoplasmic reticulum, where they are incorporated into an MHC-1 protein and trafficked to the cell surface. MHC-1 complexes activate CD8+ cytotoxic T-lymphocytes, which then kill cells that express the specific antigen to which these cells are now activated. The endogenous pathway is needed for elimination of virus-infected or cancerous cells.

Listeria generated adaptive immune responses are directed at the activation of T cells. Listeria tends not to stimulate antibody formation.

Listeria based vaccines are unique for many reasons, one of which is that unlike viral vectors, DNA or peptide antigens or other vaccines, Listeria stimulates all of the above mechanisms of immune action. We use a bioengineered form of Listeria to activate the immune system to treat cancer, infectious diseases, or allergic syndromes. Our technology allows the body to recognize tumor-associated or tumor-specific antigens as foreign, thus creating the immune response needed to attack the cancer. It does this by utilizing a number of biological characteristics of the Listeria bacteria and Advaxis proprietary antigen-fusion protein technology to stimulate multiple therapeutic immune mechanisms simultaneously in an integrated and coordinated manner.

Mechanism of Action

Listeria monocytogenes (Lm) is a bacterium well known to medical science because it can cause an infection in humans. Listeria is a rare, but serious, cause food poisoning, typically in the very old, the very young, people who are either immunocompromised or who eat a large quantity of the microbe as can occur in spoiled food. It is not laterally transmitted from person to person. As Lm is in the soil and thus found on leafy vegetables, in meat and dairy products, and is a common microbe in our environment , we are exposed to it constantly. Most people ingest Listeria without being aware of it, but in high quantities or in immune suppressed people Listeria can cause various clinical conditions, including sepsis, meningitis and placental infections in pregnant women. This is rare, and fortunately, many common antibiotics can kill and sterilize Listeria . Advaxis has a number of strains of Listeira that are bioengineered for use as a human vaccine vector. These vaccines are highly attenuated, which means they are much less pathogenic. Advaxis vaccines are between 10,000 and 100,000 times weaker (and less able to cause disease) than wild type Listeria.

Live Listeria is one of the strongest known stimulators of the innate immune system, thereby priming the adaptive immune system to better respond to the specific antigens that the Listeria carries, which viruses and other vectors do not do. This is a non-specific stimulation of the overall immune system that results when certain classes of pathogens such as bacteria are detected. It provides some level of immune protection and also serves to prime the elements of adaptive immunity to respond in a stronger way to the specific antigenic stimulus. Listeria stimulates a strong innate response which engenders a strong adaptive response.

APCs are scavenging cells in the body that circulate looking for foreign invaders. When they find one, they ingest it, break it down, and provide the fragments as molecular targets for the immune system to attack. In this way they are the cells that direct a specific immune response, and Listeria has the ability to infect them. Because Listeria infects APC, and our vaccines secrete biologically active molecules from within APC, our live attenuated Lm vaccines have the ability to direct an immune attack in a way no other therapy can.

When Listeria enters the body, it is seen as foreign by the antigen presenting cells and ingested into cellular compartments called phagolysosomes, whose destructive enzymes kill most of the bacteria. A certain percentage of these bacteria, however, are able to break out of the phagolysosomes and enter into the cytoplasm of the cell, where they are relatively safe from the immune system. The bacteria multiply in the cell, and the Listeria is able to move to its cell surface so it can push into neighboring cells and spread.

Figs 1-7. When Listeria enters the body, it is seen as foreign by the antigen presenting cells and ingested into cellular compartments called phagolysosomes, whose destructive enzymes kill most of the bacteria, fragments of which are then presented to the immune system via the exogenous pathway.

Figs 8-10. A certain percentage of bacteria is able to break out of the lysosomes and enter into the cytoplasm of the cell, where they are safe from lysosomal destruction. The bacteria multiply in the cell, and the Listeria is able to migrate into neighboring cells and spread without entering the extracellular space. Antigens produced by these bacteria enter the Class I pathway and directly stimulate a cytotoxic T cell response.

It is the details of Listeria intracellular activity that are important for understanding Advaxis technology. Inside the lysosome, Listeria produces listeriolysin-O, or LLO, a protein that creates a hole in the membrane of the lysosome that allows the bacteria to escape into the cytoplasm. Once in the cytoplasm, however, LLO is also capable of creating a hole in the outer cell membrane. This would destroy the host cell. To prevent this, the body has evolved a mechanism for recognizing enzymes with this capability based upon their amino acid sequence. The sequence of approximately 30 amino acids in LLO and similar molecules is called the PEST sequence (for the predominant amino acids it contains). When a PEST sequence is detected it is used by normal cells to force the termination of proteins that need only have a short life in the cytoplasm. This PEST sequence serves as a routing tag that tells the cells to route the LLO in the cytoplasm to the proteosome for digestion, which terminates its action and provides fragments that then go to the endoplasmic reticulum, where it is processed just like a protein antigen in the endogenous pathway to generate MHC-1 complexes.

This mechanism is used by Listeria, to its benefit, because the actions of LLO enable the bacteria to avoid digestion in the lysosome and escape to the cytosol where they can multiply and spread and then be neutralized so that it does not kill the host cell. Advaxis is using a technology that co-opts this mechanism by creating a protein that is comprised of the cancer antigen fused to a non-hemolytic portion of the LLO molecule that contains the PEST sequence. This serves to route the molecule for accelerated proteolytic degradation which accelerates both the rate of antigen breakdown and the amount of antigen fragments available for incorporation in to MHC-1 complexes; thus increasing the stimulus to activate cytotoxic T cells against a tumor -specific antigen. Moreover, LLO is a very strong adjuvant, which means it is a strong stimulator of innate immunity.

Other mechanisms that Advaxis vaccines employ include Listeria’s ability to increase the synthesis of myeloid cells such as APCs and macrophages, and to stimulate the maturation of immature myeloid cells to increase the number of available activated immune cells that underlie a cancer-killing response. Immature myeloid cells actually inhibit the immune system and Listeria removes this inhibition within the actual tumor. Also, Listeria and LLO both stimulate the synthesis, release, and expression of various chemicals which stimulate a therapeutic immune response. These chemicals are called cytokines, chemokines and co-stimulatory molecules. By doing this, not only are immune cells activated to kill cancers and clear them from the body, but local environments within tumors are created that support and facilitate a therapeutic response.

Finally, in a manner that appears to be unique to Advaxis live attenuated Listeria vaccines: they can reduce the number and function of immunosuppressive cells that tumors recruit to protect them from therapeutic immune attack. Over the past few years it has become known that the reason many previous immunologic cancer treatments have failed is that although they were able to strongly activate the immune system, they were rendered ineffective by endogenous sources of immune inhibition within the tumors themselves. Advaxis has either published scientific papers or presented data at scientific meetings about the ability of our vaccines to reduce the number of regulatory T cells (Tregs) and Myeloid Derived Suppressor Cells (MDSC); and that MDSC which remain are less immunosuppressive. This renders tumors susceptible to immune attack. The ability to reduce the effect of immunosuppressive cells within tumors is currently under clinical investigation by other companies and is believed to be a significant mechanism of achieving a therapeutic response.

Advaxis live attenuated Listeria vaccines also have the ability to modify the function of vascular endothelial cells in a way that facilitates the trafficking of activated immune cells out of the blood and into the tumor, where they are therapeutically effective. One property of cancer is the modification of vascular cells to prevent activated immune cells from transiting into the tumor. Our vaccines appear to overcome this source of anti-tumor inhibition.

Many of the immune effector cells, such as dendritic cells, macrophages, mast cells, Langerhans cells and others are myeloid cells. Our vaccines have the ability to accelerate the synthesis and maturation of these cells, as well as their antigen specific activation, to increase the power and efficiency of the immune response.

It should also be noted that the live Listeria vaccines Advaxis creates are attenuated from 10,000 to 100,000 times in order that they will not cause disease themselves. The strains of Listeria that we use are cleared by animals such as SCID mice or IFN-gamma knockout mice that lack adaptive immune responses and are thus profoundly immunocompromised.

Thus, Listeria vaccines stimulate every immune pathway simultaneously, and in an integrated manner. It has long been recognized that cytotoxic T lymphocytes, or CTL, are the elements of the immune system that kill and clear cancer cells. The amplified CTL response to Listeria vaccines are one of the strongest stimulators of CTL yet developed, but just as important is the ability Advaxis vaccines have to create a local tumor environment in which these cells can be effective. This efficacy likely results in part from the fusion of LLO to the secreted tumor antigen since many investigators have shown that LLO is a very strong source of immune stimulation independent of Listeria. By fusing a molecule with strong adjuvant properties to a tumor antigen, and then having it synthesized and secreted by live bacteria directly into the cytoplasm of Antigen Presenting Cells, vascular endothelium and other relevant tissues an unusually powerful and complete immune response is generated.

Recently we have shown that Lm-LLO vaccines can cause epitope spreading. This means that these vaccines can stimulate the immune system to respond to more antigens than the one they are designed to attack. This happens when tumor cells are killed by the immune system in response to the administered vaccine and portions of those killed cells are then recognized by the immune system and they too become targets of an immune attack. This broadens the immune attack and results in a more therapeutic response.

Thus, what makes Advaxis live Listeria vaccines so effective are a combination of effects that stimulate multiple arms of the immune system simultaneously in a manner that generates an integrated physiologic response conducive to the killing and clearing of tumor cells. These mechanisms include:

One of the strongest known stimulators of innate immunity

a. Lm-LLO vaccines are cleared in SCID mice by innate immunity alone

Stimulate a very strong adaptive immune response

a. High titers of activated CD4+, CD8+, APC, and TIL

Alters Tumor Microenvironment

a. Reduces both Tregs, MDSC & TAM in tumors but not in surrounding tissue

Stimulate synthesis of new immune cells and maturation of existing cells

a. Marrow, tissue and blood born effects

Stimulates chemotaxis and extravasation of activated immune cells

a. Chemokine mediated effects and effects directly on vascular endothelium increase TIL

Lm infects tumors with Intra-tumoral effects

a. Tumor killing, chemotaxic focus, & local innate immune effects

Initiates epitope spreading

a. Vaccines directed against one antigen result in immune activation against other antigens

Importantly, Advaxis live attenuated Listeria vaccines do not stimulate antibody formation, which is important because other types of cancer vaccines such as those that use viruses develop antibody responses which inactivate them and prevent them being used repetitively in a vaccine regimen. These types of vaccines are inactivated by antibody responses before they can effectively deliver their immune payload which prevents them from stimulating a therapeutic response. Advaxis vaccines can be used effectively in a multidose vaccine regimen as they are not inactivated by antibody responses.

Research and Development Program

Overview

We use genetically engineered and highly attenuated Listeria monocytogenes as a therapeutic agent. We start with an attenuated strain of Listeria, and then add to this bacterium multiple copies of a plasmid that encodes a fusion protein sequence that includes a fragment of the LLO molecule joined to the tumor antigen of interest. This protein is secreted by the Listeria inside the antigen presenting cells, and other cells that Listeria infects which then results in the immune response as discussed above.

We can use different tumor, infectious disease, or other antigens in this system. By varying the antigen, we create different therapeutic agents. Our lead agent, ADXS11-001, uses a HPV derived antigen that is present in cervical cancers. ADXS31-162 uses Her2/neu, an antigen found in many breast cancer and melanoma cells, to induce an immune response that should be useful in treating these conditions. ADXS31-142 is directed against PSA, and antigen of importance in prostate cancer.

Partnerships and Agreements

University of Pennsylvania

On July 1, 2002 we entered into a 20-year exclusive worldwide license agreement with Penn with respect to the innovative work of Yvonne Paterson, Ph.D., Professor of Microbiology in the area of innate immunity, or the immune response attributed to immune cells, including dendritic cells, macrophages and natural killer cells, that respond to pathogens non-specifically. This agreement has been amended from time to time and was amended and restated as of February 13, 2007.

This license, unless sooner terminated in accordance with its terms, terminates upon the later (a) expiration of the last to expire Penn patent rights; or (b) twenty years after the effective date of the license. The license provides us with the exclusive commercial rights to the patent portfolio developed at Penn as of the effective date of the license, in connection with Dr. Paterson and requires us to raise capital and pay various milestone, legal, filing and licensing payments to commercialize the technology. In exchange for the license, Penn received shares of our common stock which currently represents approximately 0.1% of our common stock outstanding on a fully-diluted basis. In addition, Penn is entitled to receive a non-refundable initial license fee, license fees, royalty payments and milestone payments based on net sales and percentages of sublicense fees and certain commercial milestones. Under the licensing agreement, Penn is entitled to receive 1.5% royalties on net sales in all countries. Notwithstanding these royalty rates, we have agreed to pay Penn a total of $525,000 over a three-year period as an advance minimum royalty after the first commercial sale of a product under each license (which we are not expecting to begin paying within the next five years). In addition, under the license, we are obligated to pay an annual maintenance fee of $100,000 on December 31, 2010, 2011 and 2012 and each December 31st thereafter for the remainder of the term of the agreement until the first commercial sale of a Penn licensed product. Overall the amended and restated agreement payment terms reflect lower near term requirements but the savings are offset by higher long term milestone payments for the initiation of a Phase III clinical trial and the regulatory approval for the first Penn licensed product. We are responsible for filing new patents and maintaining and defending the existing patents licensed to use and we are obligated to reimburse Penn for all attorneys fees, expenses, official fees and other charges incurred in the preparation, prosecution and maintenance of the patents licensed from Penn.

Furthermore, upon the achievement of the first sale of a product in certain fields, Penn will be entitled to certain milestone payments, as follows: $2.5 million will be due for first commercial sale of the first product in the cancer field. In addition, $1.0 million will be due upon the date of first commercial sale of a product in each of the secondary strategic fields sold.

As a result of our payment obligations under the license, assuming we have net sales in the aggregate amount of $100.0 million from our cancer products, our total payments to Penn over the next ten years could reach an aggregate of $5.4 million. If over the next 10 years our net sales total an aggregate amount of only $10.0 million from our cancer products, total payments to Penn could be $4.4 million.

On May 10, 2010, we entered into a second amendment to the Penn license agreement pursuant to which we acquired exclusive licenses for an additional 27 patent applications related to our proprietary Listeria vaccine technology. As per the terms of the second amendment, we acknowledged that we owed Penn approximately $249,000 in patent expenses and $130,000 in sponsored research agreement fees; such fees being paid prior to October 31, 2010. As part of this amendment we exercised our option for the rights to seven additional patent dockets, including 23 additional patent applications, for (i) an option exercise fee payable in the form of $35,000 in cash and $70,000 in our common stock (approximately 388,889 shares of our common stock based on a price of $0.18 per share) and (ii) the assumption of certain historical costs of approximately $462,000 associated with the 23 additional patents applications acquired under the second amendment. As of June 20, 2011, $138,000 of these additional costs remained outstanding.

Strategically we intend to maintain our relationship with Dr. Paterson and Penn to generate new intellectual property and to exploit all existing intellectual property covered by the license.

Penn is not involved in the management of our company or in our decisions with respect to exploitation of the patent portfolio, except that Dr. Paterson is the Chairperson of our Scientific Advisory Board.

She has trained over forty post-doctoral and doctoral students in the fields of Biochemistry and Immunology. Dr. Paterson is also the Chairman of our Scientific Advisory Board.

Consulting Agreement. On January 28, 2005 we entered into a consulting agreement with Dr. Paterson, which expired on January 31, 2009. Dr. Paterson has advised us on an exclusive basis on various issues related to our technology, manufacturing issues, establishing our lab, knowledge transfer, and our long-term research and development program. Pursuant to the expired agreement, Dr. Paterson received $7,000 per month. Upon the closing of an additional $9.0 million in equity capital, Dr. Paterson’s rates would have increased to $9,000 per month. Also, under the prior Agreement, on February 1, 2005, she received options to purchase 400,000 shares of our common stock at an exercise price of $0.287 per share which are now fully vested. In total she holds 704,365 shares of our common stock and 569,048 fully vested options to purchase shares of our common stock.

Cancer Research UK

On February 9, 2010, we announced that Cancer Research UK (CRUK), the UK organization dedicated to cancer research, has agreed to fund the cost of a clinical trial to investigate the use of ADXS11-001, our lead vaccine candidate, for the treatment of head and neck cancer. This sponsored clinical trial will investigate the safety and efficacy of ADXS11-001 in head and neck cancer patients who have previously failed treatment with surgery, radiotherapy and chemotherapy – alone or in combination. We will provide the vaccines, with all other associated costs to be funded by CRUK. The study is to be conducted at Aintree Hospital at the University of Liverpool, The Royal Marsden Hospital in London, and Cardiff Hospital at the University of Wales. At such time, enrollment officials anticipate recruiting a maximum of 45 patients.

National Cancer Institute Gynecologic Oncology Group

On December 15, 2009, we announced our Phase II Trial Collaboration with the GOG to study ADXS11-001 in a study of up to 63 patients. We will collaborate in a multicenter, Phase II clinical trial of our lead drug candidate, ADXS11-001, in the treatment of advanced cervix cancer in women who have failed prior cytotoxic therapy. This Phase II trial is underwritten by GOG and will be conducted by GOG investigators. The study’s patients are very sick and rapidly progressing similar to the population that was treated in our Phase I trial of ADXS11-001. Under this agreement we are responsible for covering the costs of translational research and have agreed to pay a total of $8,003 per patient, with the bulk of the costs of this study underwritten by NCI.

On November 1, 2010 we entered into a Collaborative Research and Development Agreement (CRADA) with the Vaccine Section of National Cancer Institute for the development of live attenuated Listeria vaccines for the treatment of cancer. We will provide all live Listeria vaccines. NCI will use different in vitro and in vivo models to elucidate the effect of our live attenuated Listeria vaccines on many different types of immune cells, and will investigate the mechanisms by which live Listeria vaccines reduce cancer induced immune inhibition that protects tumors from immune attack. We and NCI will use the results of this work to enhance the anti-tumor effects of live Listeria vaccines as therapeutic agents for the treatment of cancer and as therapeutic immune adjuvants that alter the tumor milieu which will enable them to be used with other modalities of cancer treatment. The cost of the CRADA is $150,000 annually and the length of the agreement is three years.

University of British Columbia

We entered into a structured collaboration with the laboratory of Dr. Tobias Kollmann at the University of British Columbia to develop live attenuated Listeria vaccines for the treatment of infectious disease and to develop new dosage forms of Listeria vaccines. The same immune-stimulating properties that we have under development to develop live Listeria vaccines as safe and effective therapies for the treatment of cancer, also may have application for the treatment of infectious disease. Dr. Kollmann is an immunologist and neonatal vaccinologist who has published extensively on the use of Listeria vaccines as potential therapeutic agents for the treatment of childhood diseases. Under the terms of this collaboration, Dr. Kollmann will use our proprietary Listeria vaccine vectors for the development of novel infectious disease applications.

Recipharm Cobra Biologics Limited (formerly Cobra Biomanufacturing PLC)

In July 2003, we entered into an agreement with Cobra Biomanufacturing PLC, which has recently been purchased by Recipharm AB, for the purpose of manufacturing our cervical cancer vaccine ADXS11-001. Recipharm Cobra has extensive experience in manufacturing gene therapy products for investigational studies. Recipharm Cobra is a manufacturing organization that manufactures and supplies biologic therapeutics for the pharmaceutical and biotech industry. These services include the Good Manufacturing Practices, or GMP, manufacturing of DNA, recombinant protein, viruses, mammalian cell products and cell banking. Recipharm Cobra’s manufacturing plan for us involves several manufacturing stages, including process development, manufacturing of non-GMP material for toxicology studies and manufacturing of GMP material for the Phase I trial. The agreement to manufacture expired in December 2005 upon the delivery and completion of stability testing of the GMP material for the Phase I trial. Recipharm Cobra has agreed to surrender the right to $300,000 of its outstanding fees for manufacturing in exchange for future royalties from the sales of ADXS11-001 at the rate of 1.5% of net sales, with royalty payments not to exceed $2.0 million.

On October 20, 2007, we entered into a production agreement with Recipharm Cobra to manufacture our Phase II clinical materials using a new methodology now required by the U.K., and likely to be required by other regulatory bodies in the future. Currently we have two agreements with Recipharm Cobra; one to conduct ongoing stability testing of the ADXS11-001 vaccine which they have manufactured, and another to provide analytic services and certification necessary to import ADXS11-001 for use in the U.K. head and neck study mentioned above. For the nineteen month period ended June 20, 2011, we have paid Recipharm Cobra approximately $33,000 under the agreement.

Vibalogics GmbH

In April of 2008, we entered into a series of agreements with Vibalogics GmbH in Cuxhaven Germany to provide fill and finish services for our final clinical materials that were made for the scheduled clinical trials described above. These agreements cover the fill and finish operations as well as specific tests that have to be performed in order to release the clinical materials for human use. We have recently entered into agreements with Vibalogics to produce two new vaccines, ADXS31-142 and ADXS31-164 for human use and clinical development. As of June 20, 2011, approximately $145,000 in invoices from Vibalogics GmbH remain outstanding.

Numoda Corporation

On June 19, 2009, we entered into a Master Agreement and on July 8, 2009 we entered into a Project Agreement with Numoda, a leading clinical trial and logistics management company, to oversee Phase II clinical activity with ADXS11-001 for the multicenter Phase II U.S. trial of ADXS11-001 in CIN and to act as our U.S. CRO for the multicenter Phase II study of ADXS11-001 in progressive cervix cancer being conducted in India. The scope of this agreement covers over three years and is estimated to cost $11.2 million for both trials. In May 2010, we issued 3,500,000 shares of common stock to Numoda Capital at a price per share of $0.17 in satisfaction of $595,000 of services rendered to us by the Numoda Corporation. As of June 20, 2011, we have paid Numoda approximately $5.66 million for clinical trial activities.

Pharm-Olam International Ltd.

In April 2005, we entered into a consulting agreement with Pharm-Olam International Ltd., which we refer to as POI, whereby POI is to execute and manage our Phase I clinical trial in ADXS11-001 for a fee of $430,000 plus reimbursement of certain expenses. As of June 20, 2011 we have an outstanding balance due to POI of $223,620.

Patents and Licenses

Dr. Paterson and Penn have invested significant resources and time in developing a broad base of intellectual property around the cancer vaccine platform technology for which on July 1, 2002 we entered into a 20-year exclusive worldwide license and a right to grant sublicenses pursuant to our license agreement with Penn. As of October 31, 2010 Penn has 32 issued and 33 pending patents in the U.S. and other large countries including Japan, and the European Union, through the Patent Cooperation Treaty system pursuant to which we have an exclusive license to exploit the patents. On May 10, 2010, we entered into a second amendment to the 20-year exclusive worldwide license agreement with Penn, which we refer to as the Second Amendment Agreement. Pursuant to the Second Amendment Agreement, we acquired exclusive licenses for additional patent applications related to our proprietary Listeria vaccine technology that were not included in the initial agreement. As of April 30, 2011, we acknowledged that we owe Penn approximately $138,000 in patent expenses pursuant to the Second Amendment Agreement.

Our approach to the intellectual property portfolio is to create significant offensive and defensive patent protection for every product and technology platform that we develop. We work closely with our patent counsel to maintain a coherent and aggressive strategic approach to building our patent portfolio with an emphasis in the field of cancer vaccines.

We are aware of a private company, Anza Therapeutics, Inc (formerly Cerus Corporation), which is no longer in existence, but had been developing Listeria vaccines. We are also aware of Aduro Biotech, a company comprised in part of former Cerus and Anza employees that has recently formed to investigate Listeria vaccines based upon Anza’s technology. We believe that through our exclusive license with Penn, we have the earliest known and dominant patent position in the U.S. for the use of recombinant Listeria monocytogenes expressing proteins or tumor antigens as a vaccine for the treatment of infectious diseases and tumors. We successfully defended our intellectual property by contesting a challenge made by Anza to our patent position in Europe on a claim not available in the U.S. The European Patent Office ( EPO) Board of Appeals in Munich, Germany has ruled in favor of The Trustees of Penn and its exclusive licensee Advaxis and reversed a patent ruling that revoked a technology patent that had resulted from an opposition filed by Anza. The ruling of the EPO Board of Appeals is final and cannot be appealed. The granted claims, the subject matter of which was discovered by Dr. Yvonne Paterson, scientific founder of Advaxis, are directed to the method of preparation and composition of matter of recombinant bacteria expressing tumor antigens for treatment of patients with cancer.

Based on searches of publicly available databases, we do not believe that Anza, Aduro or any other third party owns any published Listeria patents or has any issued patent claims that might materially and adversely affect our ability to operate our business as currently contemplated in the field of recombinant Listeria monocytogenes. Additionally, our proprietary position that is the issued patents and licenses for pending applications restricts anyone from using plasmid based Listeria constructs, or those that are bioengineered to deliver antigens fused to LLO, ActA, or fragments of LLO or ActA.

On January 7, 2009, we made the decision to discontinue our use of the Trademark Lovaxin and write-off of our intangible assets for trademarks resulting in an asset impairment of $91,453 as of October 31, 2008. We developed a classic coding system for our constructs. The rationale for this decision stemmed from several legal challenges to the Lovaxin name over the last two years and certain rules in Title 21 of the Code of Federal Regulations, which we refer to as the CFR, which do not allow companies to use names that are assigned to drugs in development after marketing approval. We will therefore focus company resources on product development and not the defense of the Lovaxin name.

On May 26, 2009, the United States Patent and Trademark Office, which we refer to as the PTO, approved our patent application “Compositions and Methods for Enhancing the Immunogenicity of Antigencs”. This patent application covers the use of Listeria monocytogenes protein ActA and fragments of this protein for use in the creation of antigen fusion proteins. This intellectual property protects a unique strain of Listeria monocytogenes for use as a vaccine vector.

On February 10, 2009 the PTO issued patent 7,488,487 “ Methods of Inducing Immune response Through the Administration of Auxotrophic Attenuated DAT/DAL Double Mutant Listeria Strains ”, assigned to Penn and licensed to us. This intellectual property protects a unique strain of Listeria monocytogenes for use as a vaccine vector. This new strain of Listeria is an improvement over the strain currently in clinical testing as it is more attenuated, more immunogenic, and does not have an antibiotic resistance gene inserted. We believe that this technology will make our product more effective and easier to obtain FDA regulatory approval.

Between February and December of 2009 the U.S., Japanese, and European patent offices have approved patents for a newly developed strain of Listeria that uses a novel method of attenuation. This strain is attenuated by deleting genes that are responsible for making a protein that is essential for the bacterial cell wall, and by engineering back the ability to make this protein at a reduced level. In developing this strain, the objective was to improve upon the useful properties of Listeria while reducing potential disease causing properties of the bacterium, and, in preliminary testing this strain of Listeria monocytogenes, which we refer to as Lm, appears to be more immunogenic and less virulent that prior vaccine strains.

Between January and March of 2010, the USPTO issued two patents to Penn (each of which are covered by the Penn license agreement) that cover the composition of matter, uses and methods using the Lm protein Act A in antigen fusion proteins. We are currently holding patents relating to two families of antigen-adjuvant fusion proteins; one based on LLO and one based on ActA.

Governmental Regulation

The Drug Development Process

The FDA requires that pharmaceutical and certain other therapeutic products undergo significant clinical experimentation and clinical testing prior to their marketing or introduction to the general public. Clinical testing, known as clinical trials or clinical studies, is either conducted internally by pharmaceutical or biotechnology companies or is conducted on behalf of these companies by Clinical Research Organizations, which we refer to as CROs.

The process of conducting clinical studies is highly regulated by the FDA, as well as by other governmental and professional bodies. Below, we describe the principal framework in which clinical studies are conducted, as well as describe a number of the parties involved in these studies.

Protocols . Before commencing human clinical studies, the sponsor of a new drug must typically receive governmental and institutional approval. In the U.S., Federal approval is obtained by submitting an IND to the FDA and amending it for each new proposed study. The clinical research plan is known in the industry as a protocol . A protocol is the blueprint for each drug study. The protocol sets forth, among other things, the following:

Criteria for participant inclusion/ exclusion;

Dosing requirements and timing;

Tests to be performed; and

Evaluations and data assessment.

Institutional Review Board (Ethics Committee) . An institutional review board is an independent committee of professionals and lay persons which reviews clinical research studies involving human beings and is required to adhere to guidelines issued by the FDA. The institutional review board does not report to the FDA and its members are not appointed by the FDA, but its records are audited by the FDA. All clinical studies must be approved by an institutional review board. The institutional review board is convened by the institution where the protocol will be conducted and its role is to protect the rights of the participants in the clinical studies. It must approve the protocols to be used and then oversee the conduct of the study, including oversight of the communications which we or the CRO conducting the study at that specific site proposes to use to recruit participants, and the form of consent which the participants will be required to sign prior to their participation in the clinical studies.

Clinical Trials . Human clinical studies or testing of a potential product prior to Federal approval are generally done in three stages known as Phase I, Phase II, and Phase III testing. The names of the phases are derived from the CFR 21 that regulates the FDA. Generally, there are multiple studies conducted in each phase.

Phase I . Phase I studies involve testing a drug or product on a limited number of participants. Phase I studies determine a drug’s basic safety and how the drug is absorbed by, and eliminated from, the body. This phase lasts an average of six months to a year. Typically, cancer therapies are initially tested on late stage cancer patients.

Phase II . Phase II trials involve larger numbers of participants at a time who suffer from the targeted disease or condition. Phase II testing typically lasts an average of one to three years. In Phase II, the drug is tested to determine its safety and effectiveness for treating a specific illness or condition. Phase II testing also involves determining acceptable dosage levels of the drug. If Phase II studies show that a new drug has an acceptable range of safety risks and probable effectiveness, a company will continue to review the drug in Phase III studies.

Phase III . Phase III studies involve testing even larger numbers of participants, typically several hundred to several thousand persons. The purpose is to verify effectiveness and long-term safety on a large scale. These studies generally last two to six years. Phase III studies are conducted at multiple locations or sites. Like the other phases, Phase III requires the site to keep detailed records of data collected and procedures performed.

Biologic License Application. The results of the clinical trials using biologics are submitted to the FDA as part of Biologic License Application, which we refer to as BLA. Following the completion of Phase III studies, if the sponsor of a potential product in the U.S. believes it has sufficient information to support the safety and effectiveness of their product, the sponsor submits a BLA to the FDA requesting that the product be approved for sale. The application is a comprehensive, multi-volume filing that includes the results of all preclinical and clinical studies, information about the drug’s composition, and the sponsor’s plans for producing, packaging, labeling and testing the product. The FDA’s review of an application can take a few months to many years, with the average review lasting 18 months. Once approved, drugs and other products may be marketed in the U.S., subject to any conditions imposed by the FDA.

The drug approval process is time-consuming, involves substantial expenditures of resources, and depends upon a number of factors, including the severity of the illness in question, the availability of alternative treatments, and the risks and benefits demonstrated in the clinical trials.

On November 21, 1997, former President Clinton signed into law the FDA Modernization Act. That act codified the FDA’s policy of granting “Fast Track” approval for cancer therapies and other therapies intended to treat serious or life threatening diseases and that demonstrate the potential to address unmet medical needs. The Fast Track program emphasizes close, early communications between the FDA and the sponsor to improve the efficiency of preclinical and clinical development, and to reach agreement on the design of the major clinical efficacy studies that will be needed to support approval. Under the Fast Track program, a sponsor also has the option to submit and receive review of parts of the NDA or BLA on a rolling schedule approved by FDA, which expedites the review process.

The FDA’s Guidelines for Industry Fast Track Development Programs require that a clinical development program must continue to meet the criteria for Fast Track designation for an application to be reviewed under the Fast Track Program. Previously, the FDA approved cancer therapies primarily based on patient survival rates or data on improved quality of life. While the FDA could consider evidence of partial tumor shrinkage, which is often part of the data relied on for approval, such information alone was usually insufficient to warrant approval of a cancer therapy, except in limited situations. Under the FDA’s new policy, which became effective on February 19, 1998, Fast Track designation ordinarily allows a product to be considered for accelerated approval through the use of surrogate endpoints to demonstrate effectiveness. As a result of these provisions, the FDA has broadened authority to consider evidence of partial tumor shrinkage or other surrogate endpoints of clinical benefit for approval. This new policy is intended to facilitate the study of cancer therapies and shorten the total time for marketing approvals. Under accelerated approval, the manufacturer must continue with the clinical testing of the product after marketing approval to validate that the surrogate endpoint did predict meaningful clinical benefit. To the extent applicable, we intend to take advantage of the Fast Track Program to obtain accelerated approval on our future products, however, it is too early to tell what effect, if any, these provisions may have on the approval of our product candidates.

Other Regulations

Various Federal and state laws, regulations, and recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import, export, use, and disposal of hazardous or potentially hazardous substances, including radioactive compounds and infectious disease agents, are used in connection with our research or applicable to our activities. They include, among others, the U.S. Atomic Energy Act, the Clean Air Act, the Clean Water Act, the Occupational Safety and Health Act, the National Environmental Policy Act, the Toxic Substances Control Act, and Resources Conservation and Recovery Act, national restrictions on technology transfer, import, export, and customs regulations, and other present and possible future local, state, or federal regulation. The extent of governmental regulation which might result from future legislation or administrative action cannot be accurately predicted.

There is a series of international harmonization treaties, known as the ICH treaties, that enable drug development to be conducted on an international basis. These treaties specify the manner in which clinical trials are to be conducted, and if trials adhere to the specified requirements, then they are accepted by the regulatory bodies in the signatory countries. In this way, the Advaxis Phase I study conducted outside of the U.S. is accepted by the FDA.

Manufacturing

The FDA requires that any drug or formulation to be tested in humans be manufactured in accordance with its GMP regulations. This has been extended to include any drug that will be tested for safety in animals in support of human testing. The GMPs set certain minimum requirements for procedures, record-keeping, and the physical characteristics of the laboratories used in the production of these drugs.

We have entered into agreements with Recipharm Cobra and Vibalogics GmbH for the manufacture of a portion of our vaccines. Both companies have extensive experience in manufacturing gene therapy products for investigational studies. Both companies are full service manufacturing organizations that manufacture and supply biologic based therapeutics for the pharmaceutical and biotech industry. These services include the GMP manufacturing of stability testing and cell banking. Recipharm’s manufacturing plan for us calls for several manufacturing stages, including process development, manufacturing of non-GMP material for toxicology studies and manufacturing of GMP material for the Phase I and Phase II trials.

Beginning in April 2008, we entered into a number of Agreements with Vibalogics to manufacture clinical grade material for two new vaccines to develop in the clinic as new drugs; ADXS31-142, a vaccine for the treatment of prostate cancer, and ADXS31-164, a vaccine for the treatment of breast, brain and other cancers. Recipharm Cobra’s manufacturing plan for us calls for GMP manufacturing in several stages, including process development, manufacturing of non-GMP material for toxicology studies and manufacturing of GMP material for the Phase I and Phase II trials, filling, finishing, and the development of a storage stable, room temperature, dried form of our vaccines.

Competition

The biotechnology and biopharmaceutical industries are characterized by rapid technological developments and a high degree of competition. As a result, our actual or proposed products could become obsolete before we recoup any portion of our related research and development and commercialization expenses. The biotechnology and biopharmaceutical industries are highly competitive, and this competition comes from both biotechnology firms and from major pharmaceutical and chemical companies, including Aduro Biotech, Antigenics Inc., Avi BioPharma, Inc., Biomura Inc., Biovest International, Biosante Pharmaceuticals Inc., Dendreon Corporation, Pharmexa-Epimmune Inc. , Genzyme Corp., Progenics Pharmaceuticals Inc. and Vical Incorporated each of which is pursuing cancer vaccines. Many of these companies have substantially greater financial, marketing, and human resources than we do (including, in some cases, substantially greater experience in clinical testing, manufacturing, and marketing of pharmaceutical products). We also experience competition in the development of our products from universities and other research institutions and compete with others in acquiring technology from such universities and institutions. In addition, certain of our products may be subject to competition from products developed using other technologies, some of which have completed numerous clinical trials.

We expect that our products under development and in clinical trials will address major markets within the cancer sector. Our competition will be determined in part by the potential indications for which drugs are developed and ultimately approved by regulatory authorities. Additionally, the timing of market introduction of some of our potential products or of competitors’ products may be an important competitive factor. Accordingly, the speed with which we can develop products, complete preclinical testing, clinical trials and approval processes and supply commercial quantities to market are expected to be important competitive factors. We expect that competition among products approved for sale will be based on various factors, including product efficacy, safety, reliability, availability, price and patent position.

Merck has developed the drug Gardasil and GSK has developed the drug Cervarix which can prevent cervical cancer by vaccinating women against the virus HPV, the cause of the disease. Gardasil is directed against four HPV strains while Cervarix is directed against two. Neither of these agents has an approved indication for women who have a prior exposure to the HPV strains that they protect against, nor are women protected from other strains of HPV that the drugs do not treat. It has been written that these are cancer vaccines, which is not true. They are anti-virus vaccines intended to protect against strains of the HPV virus.

The presence of these agents in the market does not eliminate the market for a therapeutic vaccine directed against invasive cervical cancer and CIN for a number of reasons:

HPV is the most common sexually treated disease in the U.S., and since prior exposure to the virus renders these anti-viral agents ineffective they tend to be limited to younger women and do not offer protection for women who are already infected. The number of women who are already infected with HPV is estimated to be as much as (or more than) 25% of the female population of the U.S.

There are approximately 10 high risk strains of HPV, but these agents only protect against the most common 2-4 strains. If a woman contracts a high risk HPV species that is not one of those, the drugs will not work.

Women with HPV are typically infected for over twenty years or more before they manifest cervical cancer. Thus, the true prophylactic effect of these drugs can only be inferred at this time. We believe that there currently exists a significant population of young woman who have not received these agents, or for whom they will not work, and who will manifest HPV related cervical disease for the next 40+ years. We believe this population will continue to grow until such time as a significant percentage of women who have not been exposed to HPV are vaccinated; which we believe is not likely to occur within the next decade or longer. We do not know at this time whether a significant number of women will be vaccinated to have an effect on the epidemiology of this disease.

With the exception of the campaign to eradicate polio in which vaccination was mandatory for all school age children, vaccination is a difficult model to accomplish because it is virtually impossible to treat everyone in any given country, much less the entire world. This is especially true for cervical cancer, as the incentive for men to be vaccinated is small, and infected men keep the pathogen circulating in the population.

Taken together, experts believe that there will be a cervical cancer and CIN market for the foreseeable future.

Thomas A. Moore. Mr. Moore joined our Board as an independent director in September 2006. Effective December 15, 2006, Mr. Moore was appointed our Chairman and Chief Executive Officer. He is currently also a director of MD Offices, an electronic medical records provider, and Opt-e-scrip, Inc., which markets a clinical system to compare multiple drugs in the same patient. He also serves as Chairman of the board of directors of Mayan Pigments, Inc., which has developed and patented Mayan pigment technology. Previously, from June 2002 to June 2004 Mr. Moore was President and Chief Executive Officer of Biopure Corporation, a developer of oxygen therapeutics that are intravenously administered to deliver oxygen to the body’s tissues. From 1996 to November 2000 he was President and Chief Executive Officer of Nelson Communications. Prior to 1996, Mr. Moore had a 23-year career with the Procter & Gamble Company in multiple managerial positions, including President of Health Care Products where he was responsible for prescription and over-the-counter medications worldwide, and Group Vice President of the Procter & Gamble Company. Mr. Moore is a graduate of Princeton University. Mr. Moore’s extensive business, managerial, executive and leadership experience in the healthcare industry make him particularly qualified to serve on our Board.

Mr. Moore is subject to a five year injunction, which came about because of a civil action captioned Securities & Exchange Commission v. Biopure Corp. et al., No. 05-11853-PBS (D. Mass.), filed on September 14, 2005, which alleged that Mr. Moore made and approved misleading public statements about the status of FDA regulatory proceedings concerning a product manufactured by his former employer, Biopure Corp. Mr. Moore vigorously defended the action. On December 11, 2006, the SEC and Mr. Moore jointly sought a continuance of all proceedings based upon a tentative agreement in principle to settle the SEC action. The SEC’s Commissioners approved the terms of the settlement, and the court formally adopted the settlement.

Dr. James Patton. Dr. Patton has served as a member of our board of directors since February 2002, as Chairman of our board of directors from November 2004 until December 31, 2005 and as Advaxis’ Chief Executive Officer from February 2002 to November 2002. Since February 1999, Dr. Patton was the Vice President of Millennium Oncology Management, Inc., which provides management services for radiation oncology care to four sites. Dr. Patton has been a trustee of Dundee Wealth US, a mutual fund family since October 2006. In addition, he has been President of Comprehensive Oncology Care, LLC since 1999, a company which owned and operated a cancer treatment facility in Exton, Pennsylvania until its sale in 2008. From February 1999 to September 2003, Dr. Patton also served as a consultant to LibertyView Equity Partners SBIC, LP, a venture capital fund based in Jersey City, New Jersey. From July 2000 to December 2002, Dr. Patton served as a director of Pinpoint Data Corp. From February 2000 to November 2000, Dr. Patton served as a director of Healthware Solutions. From June 2000 to June 2003, Dr. Patton served as a director of LifeStar Response. He earned his B.S. from the University of Michigan, his Medical Doctorate from Medical College of Pennsylvania, and his M.B.A. from Penn’s Wharton School. Dr. Patton was also a Robert Wood Johnson Foundation Clinical Scholar. He has published papers regarding scientific research in human genetics, diagnostic test performance and medical economic analysis. Dr. Patton’s experience as a trustee and consultant to funds that invest in life science companies provide him with the perspective from which we benefit. Additionally, Dr. Patton’s medical experience and service as a principal and director of other life science companies makes Dr. Patton particularly qualified to serve as our director.

Roni A. Appel. Mr. Appel has served as a member of our board of directors since November 2004. He was our President and Chief Executive Officer from January 1, 2006 and Secretary and Chief Financial Officer from November 2004, until he resigned as our Chief Financial Officer on September 7, 2006 and as our President, Chief Executive Officer and Secretary on December 15, 2006.

From 1998 until 1999, he was a director of business development at Americana Financial Services, Inc. From 1994 to 1998 he was an attorney and completed his MBA at Columbia University. Mr. Appel’s longstanding service with us and his entrepreneurial investment career in early stage biotech businesses qualify him to serve as our director.

Dr. Thomas McKearn . Dr. McKearn has served as a member of our board of directors since July 2002. He brings more than 25 years of experience in the translation of biotechnology science into oncology products. First as one of the founders of Cytogen Corporation, then as an Executive Director of Strategic Science and Medicine at Bristol-Myers Squibb and now as the VP of Strategic Medical Affairs at Agennix, Inc.

Prior to entering the biotechnology industry in 1981, Dr. McKearn received his medical, graduate and post-graduate training at the University of Chicago and served on the faculty of the Medical School at the University of Pennsylvania. Dr. McKearn’s experience in managing life science companies, his knowledge of medicine and his commercialization of biotech products particularly qualify him to serve as our director.

Richard Berman. Mr. Berman has served as a member of our board of directors since September 1, 2005. In the last five years, he served as a professional director and/or officer of about a dozen public and private companies.

Board of Directors

Each director is elected for a period of one year and serves until the next annual meeting of stockholders, or until his or her successor is duly elected and qualified. Officers are elected by, and serve at the discretion of, our board of directors. The board of directors may also appoint additional directors up to the maximum number permitted under our by-laws, which is currently nine.

Director Independence

In accordance with the disclosure requirements of the SEC, and since the OTC Bulletin Board does not have its own rules for director independence, we have adopted the NASDAQ listing standards for independence effective April 2010. Although we are not presently listed on any national securities exchange, each of our directors, other than Mr. Thomas A. Moore and Mr. Roni Appel, is independent in accordance with the definition set forth in the NASDAQ rules. Each current member of the Audit Committee and Compensation Committee is an independent director under the NASDAQ standards. The Board considered the information included in transactions with related parties as outlined below along with other information the Board considered relevant, when considering the independence of each director.

Committees of the Board of Directors

Our board of directors has three standing committees: the audit committee, the compensation committee, and the nominating and corporate governance committee.

Audit Committee

The audit committee of our board of directors is currently composed of two directors, both of whom satisfy the independence standards for audit committee members under the NASDAQ rules (although our securities are not listed on the NASDAQ stock market but are quoted on the OTC Bulletin Board). For fiscal 2010, the audit committee was composed of Mr. Berman and Dr. Patton, with Mr. Berman serving as the audit committee’s financial expert as defined under Item 407 of Regulation S-K of the Securities Act of 1933, as amended, which we refer to as the Securities Act. Our board of directors has determined that the audit committee financial expert is independent as defined in (i) Rule 10A-3(b)(i)(ii) under the Exchange Act and (ii) under Section 121 B(2)(a) of the NYSE Amex Equities Company Guide (although our securities are not listed on the NYSE Amex Equities but are quoted on the OTC Bulletin Board).

The audit committee is responsible for the following:

reviewing the results of the audit engagement with the independent registered public accounting firm;

identifying irregularities in the management of our business in consultation with our independent accountants, and suggesting an appropriate course of action;

reviewing the adequacy, scope, and results of the internal accounting controls and procedures;

reviewing the degree of independence of the auditors, as well as the nature and scope of our relationship with our independent registered public accounting firm;

reviewing the auditors’ fees; and

recommending the engagement of auditors to the full board of directors.

Compensation Committee

The compensation committee of our board of directors consists of Mr. Berman and Dr. McKearn. The compensation committee determines the salaries and incentive compensation of our officers subject to applicable employment agreements, and provides recommendations for the salaries and incentive compensation of our other employees and consultants.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee of our board of directors currently consists of Mr. Berman and Mr. Moore. The nominating and corporate governance committee did not meet in fiscal 2010. The functions of the nominating and corporate governance committee include the following:

identifying and recommending to the board of directors individuals qualified to serve as members of our board of directors and on the committees of the board;

advising the board with respect to matters of board composition, procedures and committees;

developing and recommending to the board a set of corporate governance principles applicable to us and overseeing corporate governance matters generally including review of possible conflicts and transactions with persons affiliated with directors or members of management; and

overseeing the annual evaluation of the board and our management.

The nominating and corporate governance committee will consider director candidates recommended by eligible stockholders. Stockholders may recommend director nominees for consideration by the nominating and corporate governance committee by writing to the Nominating and Corporate Governance, Attention: Chairman, Advaxis, Inc., 305 College Road East, Princeton, New Jersey 08540. Any recommendations for director made to the nominating and corporate governance committee should include the nominee’s name and qualifications for membership on our board of directors, and should include the following information for each person being recommended or nominated for election as a director:

The name, age, business address and residence address of the person;

The principal occupation or employment of the person;

The number of shares of our common stock which the person owns beneficially or of record; and

Any other information relating to the person that must be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors under Section 14 of the Exchange Act and its rules and regulations.

In addition, the stockholder’s notice must include the following information about such stockholder:

The stockholder’s name and record address;

The number of shares of our common stock that the stockholder owns beneficially or of record;

A description of all arrangements or understandings between the stockholder and each proposed nominee and any other person or persons, including their names, pursuant to which the nomination is to be made;

A representation that the stockholder intends to appear in person or by proxy at the annual meeting to nominate the person or persons named in such stockholder’s notice; and

Any other information about the stockholder that must be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors under Section 14 of the Exchange Act and its rules and regulations.

The notice must include a written consent by each proposed nominee to being named as a nominee and to serve as a director if elected. No person will be eligible for election as a director of ours unless recommended by the nominating and corporate governance committee and nominated by our board of directors or nominated in accordance with the procedures set forth above. Candidates proposed by stockholders for nomination are evaluated using the same criteria as candidates initially proposed by the nominating and corporate governance committee.

We must receive the written nomination for an annual meeting not less than 90 days and not more than 120 days prior to the first anniversary of the previous year’s annual meeting of stockholders, or, if no annual meeting was held the previous year or the date of the annual meeting is advanced more than 30 days before or delayed more than 60 days after the anniversary date, we must receive the written nomination not more than 120 days prior to the annual meeting and not less than the later of 90 days prior to the annual meeting or ten days following the day on which public announcement of the date of the annual meeting is first made. For a special meeting, we must receive the written nomination not less than the later of 90 days prior to the special meeting or ten days following the day on which public announcement of the date of the special meeting is first made.

The nominating and corporate governance committee expects, as minimum qualifications, that nominees to our board of directors (including incumbent directors) will enhance our board of director’s management, finance and/or scientific expertise, will not have a conflict of interest and will have a high ethical standard. A director nominee’s knowledge and/or experience in areas such as, but not limited to, the medical, biotechnology, or life sciences industry, equity and debt capital markets and financial accounting are likely to be considered both in relation to the individual’s qualification to serve on our board of directors and the needs of our board of directors as a whole. Other characteristics, including but not limited to, the director nominee’s material relationships with us, time availability, service on other boards of directors and their committees, or any other characteristics which may prove relevant at any given time as determined by the nominating and corporate governance committee shall be reviewed for purposes of determining a director nominee’s qualification.

Candidates for director nominees are evaluated by the nominating and corporate governance committee in the context of the current composition of our board of directors, our operating requirements and the long-term interests of our stockholders. The nominating and corporate governance committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The nominating and corporate governance committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of our board of directors. In the case of incumbent directors whose terms of office are set to expire, the nominating and corporate governance committee reviews such directors’ overall service to us during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. The nominating and corporate governance committee meets to discuss and consider such candidates’ qualifications and then selects a nominee for recommendation to our board of directors by majority vote. To date, the nominating and corporate governance committee has not paid a fee to any third party to assist in the process of identifying or evaluating director candidates.

Compensation Committee Interlocks and Insider Participation

The current members of the compensation committee are Mr. Berman and Dr. McKearn. Currently, none of such persons is an officer or employee of us or any of our subsidiaries. During fiscal 2010, none of our executive officers served as a director or member of a compensation committee (or other committee serving an equivalent function) of any other entity, whose executive officers served as a director or member of our compensation committee. No interlocking relationship, as defined by the Securities Exchange Act of 1934, as amended, exists between our board of directors or our Compensation Committee and the board of directors or compensation committee of any other company.

Discussion of Summary Compensation Table

We are party to an employment agreement with each of our named executive officers who is presently employed by us, other than Mr. Rosenblum. Each employment agreement sets forth the terms of that officer’s employment, including among other things, salary, bonus, non-equity incentive plan and other compensation, and its material terms are described below. In fiscal 2009 and fiscal 2010, we granted stock options to our named executive officers to purchase shares of our common stock and issued stock to our Chief Executive Officer. The material terms of these grants are also described below.

Moore Employment Agreement and Option Agreements. We are party to an employment agreement with Mr. Moore, dated as of August 21, 2007 (memorializing an oral agreement dated December 15, 2006), that provides that he will serve as our Chairman of the Board and Chief Executive Officer for an initial term of two years. For so long as Mr. Moore is employed by us, Mr. Moore is also entitled to nominate one additional person to serve on our board of directors. Following the initial term of employment, the agreement was renewed for a one year term, and is automatically renewable for additional successive one year terms, subject to our right and Mr. Moore’s right not to renew the agreement upon at least 90 days’ written notice prior to the expiration of any one year term.

Under the terms of the agreement, Mr. Moore was entitled to receive a base salary of $250,000 per year, subject to increase to $350,000 per year upon our successful raise of at least $4.0 million (which condition was satisfied on November 1, 2007) and subject to annual review for increases by our board of directors in its sole discretion. The agreement also provides that Mr. Moore is entitled to receive family health insurance at no cost to him. Mr. Moore’s employment agreement does not provide for the payment of a bonus.

Director Compensation

All of our non-employee directors earn a combination of cash compensation and awards of shares of our common stock. Each non-employee director (other than Mr. Berman) earns 6,000 shares of our common stock per quarter. Additionally, each non-employee director earns $2,000 for each board meeting attended in person and $750 for each telephonic board meeting. In addition, each member of a committee of the Board earns $2,000 per meeting attended in person held on days other than board meeting days and $750 for each telephonic committee meeting. In addition, Mr. Berman, earns $2,000 a month in shares of our common stock based on the average closing price of our common stock for the preceding month. The non-employee director compensation that was earned for the twelve months ended October 31, 2010, was not paid or issued. Our employee director does not receive any compensation for his services as a director.

The table below summarizes the compensation that was earned by our non-employee directors for fiscal 2010. As none of our non-employee directors received non-equity incentive plan compensation or nonqualified deferred compensation earnings during fiscal 2010, we have omitted those columns from the table.

2004 Stock Option Plan

In November 2004, our board of directors adopted and our stockholders approved the 2004 Stock Option Plan, which we refer to as the 2004 plan. The 2004 plan provides for the grant of options to purchase up to 2,381,525 shares of our common stock to employees, officers, directors and consultants. Options may be either “incentive stock options” or non-qualified options under the Federal tax laws. Incentive stock options may be granted only to our employees, while non-qualified options may be issued, in addition to employees, to non-employee directors and consultants. As of June 20, 2011, options to purchase 2,319,025 shares of our common stock have been granted under the 2004 plan.

The 2004 plan is administered by “disinterested members” of our board of directors or the compensation committee, who determine, among other things, the individuals who will receive options, the time period during which the options may be partially or fully exercised, the number of shares of common stock issuable upon the exercise of each option and the option exercise price.

Subject to a number of exceptions, the exercise price per share of common stock subject to an incentive option may not be less than the fair market value per share of common stock on the date the option is granted. The per share exercise price of our common stock subject to a non-qualified option may be established by our board of directors, but will not, however, be less than 85% of the fair market value per share of common stock on the date the option is granted. The aggregate fair market value of common stock for which any person may be granted incentive stock options which first become exercisable in any calendar year may not exceed $100,000 on the date of grant.

No stock option may be transferred by an optionee other than by will or the laws of descent and distribution, and, during the lifetime of an optionee, the option will be exercisable only by the optionee. In the event of termination of employment or engagement other than by death or disability, the optionee will have no more than three months after such termination during which the optionee will be entitled to exercise the option to the extent vested at termination, unless otherwise determined by our board of directors. Upon termination of employment or engagement of an optionee by reason of death or permanent and total disability, the optionee’s options remain exercisable for one year to the extent the options were exercisable on the date of such termination. No similar limitation applies to non-qualified options.

We must grant options under the 2004 plan within ten years from the effective date of the 2004 plan. The effective date of the 2004 plan was November 12, 2004. Subject to a number of exceptions, holders of incentive stock options granted under the 2004 plan cannot exercise these options more than ten years from the date of grant. Options granted under the 2004 plan generally provide for the payment of the exercise price in cash and may provide for the payment of the exercise price by delivery to us of shares of common stock already owned by the optionee having a fair market value equal to the exercise price of the options being exercised, or by a combination of these methods. Therefore, if it is provided in an optionee’s options, the optionee may be able to tender shares of common stock to purchase additional shares of common stock and may theoretically exercise all of his stock options with no additional investment other than the purchase of his original shares.

Any unexercised options that expire or that terminate upon an employee’s ceasing to be employed by us become available again for issuance under the 2004 plan.

2005 Stock Option Plan

In June 2006 our board of directors adopted, and on June 6, 2006 our stockholders approved, the 2005 Stock Option Plan, which we refer to as the 2005 plan.

The 2005 plan provides for the grant of options to purchase up to 5,600,000 shares of our common stock to employees, officers, directors and consultants. Options may be either “incentive stock options” or non-qualified options under the Federal tax laws. Incentive stock options may be granted only to our employees, while non-qualified options may be issued to non-employee directors, consultants and others, as well as to our employees. As of March 21, 2011, options to purchase 5,429,917 shares of our common stock have been granted under the 2005 plan.

The 2005 plan is administered by “disinterested members” of our board of directors or the compensation committee, who determine, among other things, the individuals who will receive options, the time period during which the options may be partially or fully exercised, the number of shares of common stock issuable upon the exercise of each option and the option exercise price.

Except when agreed to by our board of directors or the administrator of the 2005 plan, no stock option may be transferred by an optionee other than by will or the laws of descent and distribution, and, during the lifetime of an optionee, the option will be exercisable only by the optionee. In the event of termination of employment or engagement other than by death or disability, the optionee will have no more than three months after such termination during which the optionee will be entitled to exercise the option, unless otherwise determined by our board of directors. Upon termination of employment or engagement of an optionee by reason of death or permanent and total disability, the optionee’s options remain exercisable for one year to the extent the options were exercisable on the date of such termination. No similar limitation applies to non-qualified options.

We must grant options under the 2005 plan within ten years from the effective date of the 2005 plan. The effective date of the 2005 plan was January 1, 2005. Subject to a number of exceptions, holders of incentive stock options granted under the 2005 plan cannot exercise these options more than ten years from the date of grant. Options granted under the 2005 plan generally provide for the payment of the exercise price in cash and may provide for the payment of the exercise price by delivery to us of shares of common stock already owned by the optionee having a fair market value equal to the exercise price of the options being exercised, or by a combination of these methods. Therefore, if it is provided in an optionee’s options, the optionee may be able to tender shares of common stock to purchase additional shares of common stock and may theoretically exercise all of his stock options with no additional investment other than the purchase of his original shares.

Any unexercised options that expire or that terminate upon an employee’s ceasing to be employed by us become available again for issuance under the 2005 plan.

2009 Stock Option Plan

Our board of directors adopted the 2009 Stock Option Plan effective July 21, 2009, and recommended that it be submitted to our shareholders for their approval at the next annual meeting. On April 23, 2010, our board of directors approved and adopted, and on June 1, 2010 our stockholders approved, the amended and restated 2009 Stock Option Plan, which we refer to as the 2009 plan. An aggregate of 20,000,000 shares of our common stock (subject to adjustment by the compensation committee) are reserved for issuance upon the exercise of options granted under the 2009 plan. As of June 20, 2011, options to purchase 19,850,000 shares of our common stock are outstanding under the 2009 plan and no options to purchase shares of our common stock remain available for issuance under the 2009 plan.

The 2009 plan is to be administered by the compensation committee of our board of directors; provided, however, that except as otherwise expressly provided in the 2009 plan, our board of directors may exercise any power or authority granted to the compensation committee under the 2009 plan. Subject to the terms of the 2009 plan, the compensation committee is authorized to select eligible persons to receive options, determine the type, number and other terms and conditions of, and all other matters relating to, options, prescribe option agreements (which need not be identical for each participant), and the rules and regulations for the administration of the 2009 plan, construe and interpret the 2009 plan and option agreements, correct defects, supply omissions or reconcile inconsistencies therein, and make all other decisions and determinations as the compensation committee may deem necessary or advisable for the administration of the 2009 plan.

The maximum number of shares of common stock to which options may be granted to any one individual under the 2009 plan is 6,000,000 (subject to adjustment by the compensation committee). The shares acquired upon exercise of options granted under the 2009 plan will be authorized and issued shares of our common stock. Our shareholders will not have any preemptive rights to purchase or subscribe for any common stock by reason of the reservation and issuance of common stock under the 2009 plan. If any option granted under the 2009 plan should expire or terminate for any reason other than having been exercised in full, the unpurchased shares subject to that option will again be available for purposes of the 2009 plan.

The persons eligible to receive awards under the 2009 plan are the officers, directors, employees, consultants and other persons who provide services to us or any related entity. An employee on leave of absence may be considered as still in our or a related entity’s employ for purposes of eligibility for participation in the 2009 plan. All options granted under the 2009 plan must be evidenced by a written agreement. The agreement will contain such terms and conditions as the compensation committee shall prescribe, consistent with the 2009 plan, including, without limitation, the exercise price, term and any restrictions on the exercisability of the options granted. For any option granted under the 2009 plan, the exercise price per share of common stock may be any price determined by the compensation committee; however, the exercise price per share of any incentive stock option may not be less than the fair market value of the common stock on the date such incentive stock option is granted.

The compensation committee may permit the exercise price of an option to be paid for in cash, by certified or official bank check or personal check, by money order, with already owned shares of common stock that have been held by the optionee for at least six (6) months (or such other shares as we determine will not cause us to recognize for financial accounting purposes a charge for compensation expense), the withholding of shares of common stock issuable upon exercise of the option, by delivery of a properly executed exercise notice together with such documentation as shall be required by the compensation committee (or, if applicable, the broker) to effect a cashless exercise, or a combination of the above. If paid in whole or in part with shares of already owned common stock, the value of the shares surrendered is deemed to be their fair market value on the date the option is exercised.

No incentive stock option, and unless the prior written consent of our compensation committee is obtained (which consent may be withheld for any reason) and the transaction does not violate the requirements of Rule 16b-3 of the Exchange Act, no non-qualified stock option granted under the 2009 plan is assignable or transferable, other than by will or by the laws of descent and distribution. During the lifetime of an optionee, an option is exercisable only by him or her, or in the case of a non-qualified stock option, by his or her permitted assignee.

The expiration date of an option under the 2009 plan will be determined by our compensation committee at the time of grant, but in no event may such an option be exercisable after 10 years from the date of grant. An option may be exercised at any time or from time to time or only after a period of time in installments, as determined by our compensation committee. Our compensation committee may in its sole discretion accelerate the date on which any option may be exercised. Each outstanding option granted under the 2009 plan may become immediately fully exercisable in the event of certain transactions, including certain changes in control of us, certain mergers and reorganizations, and certain dispositions of substantially all our assets.

Unless otherwise provided in the option agreement, the unexercised portion of any option granted under the 2009 plan shall automatically be terminated (a) three months after the date on which the optionee’s employment is terminated for any reason other than (i) cause (as defined in the 2009 plan), (ii) mental or physical disability, or (iii) death; (b) immediately upon the termination of the optionee’s employment for cause; (c) one year after the date on which the optionee’s employment is terminated by reason of mental or physical disability; or (d) one year after the date on which the optionee’s employment is terminated by reason of optionee’s death, or if later, three months after the date of optionee’s death if death occurs during the one year period following the termination of the optionee’s employment by reason of mental or physical disability.

Unless earlier terminated by our board, the 2009 plan will terminate at the earliest of (a) such time as no shares of common stock remain available for issuance under the 2009 plan, (b) termination of the 2009 plan by our board, or (c) the tenth anniversary of the effective date of the 2009 plan. Options outstanding upon expiration of the 2009 plan shall remain in effect until they have been exercised or terminated, or have expired.

STOCK OWNERSHIP

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of June 20, 2011 of:

each person who is known by us to be the beneficial owner of more than 5% of our outstanding common stock;

each of our directors;

each of our named executive officers; and

all of our directors and executive officers as a group.

As used in the table below and elsewhere in this prospectus, the term beneficial ownership with respect to our common stock consists of sole or shared voting power (which includes the power to vote, or to direct the voting of shares of our common stock) or sole or shared investment power (which includes the power to dispose, or direct the disposition of, shares of our common stock) through any contract, arrangement, understanding, relationship or otherwise, including a right to acquire such power(s) during the 60 days following June 20, 2011.

Unless otherwise indicated in the footnotes to this table, and subject to community property laws where applicable, we believe each of the stockholders named in this table has sole voting and investment power with respect to the shares indicated as beneficially owned. Applicable percentages are based on 230,083,519 shares of common stock outstanding as of June 20, 2011, adjusted as required by the rules promulgated by the SEC. Unless otherwise indicated, the address for each of the individuals and entities listed in this table is 305 College Road East, Princeton, New Jersey 08540.

SELLING STOCKHOLDER

The selling stockholder may offer and sell, from time to time, any or all of the shares of common stock covered by this prospectus. The following table provides, as of June 20, 2011, information regarding the beneficial ownership of our common stock held by each selling stockholder (including holders of warrants for shares being registered), the shares that may be sold by each selling stockholder under this prospectus and the number of shares of common stock that each selling stockholder will beneficially own after this offering.

The information set forth in the table and related footnotes are prepared based on our transfer agent’s records as of June 20, 2011 and information provided to us by or on behalf of the selling stockholder. Applicable percentages are based on 230,083,519 shares of common stock outstanding as of June 20, 2011, adjusted as required by the rules promulgated by the SEC. Because the selling stockholder may dispose of all, none or some portion of the shares, no estimate can be given as to the number of shares that will be beneficially owned by the selling stockholder upon termination of this offering. For purposes of the table below, however, we have assumed that after termination of this offering none of the shares covered by this prospectus will be beneficially owned by the selling stockholder and further assumed that the selling stockholder will not acquire beneficial ownership of any additional shares during the offering. In addition, the selling stockholder may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, the shares of our common stock in transactions exempt from the registration requirements of the Securities Act of 1933 after the date on which the information in the table is presented.

We may amend or supplement this prospectus from time to time in the future to update or change this selling stockholder list and the shares that may be resold.

(1)

Except as otherwise indicated in the footnotes to this table, the number and percentage of shares beneficially owned is determined in accordance with Rule 13d-3 of the Exchange Act, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rule, beneficial ownership includes any shares as to which the selling stockholder has sole or shared voting power or investment power and also any shares, which the selling stockholder has the right to acquire within 60 days.

(2)

Consists of a warrant to purchase 25,560,000 shares of our common stock. On April 4, 2011, we issued to Optimus CG II, Ltd., in connection with the amendment to the Series B purchase agreement, a three-year warrant to purchase up to 25,560,000 shares of our common stock, at an initial exercise price of $0.15 per share, subject to adjustment as provided elsewhere in this prospectus. The warrant will become exercisable upon the effectiveness of the registration statement of which this prospectus forms a part. Voting and dispositive power with respect to the shares held by Optimus CG II, Ltd. is exercised by Ward Jensen, its Vice President–Trading. However, the warrant contains restrictive covenants under which the holder is prohibited from: (1) voting any shares of our common stock owned or controlled by the holder or soliciting any proxies or seeking to advise or influence any person with respect to any of our voting securities; (2) engaging or participating in any actions, plans or proposals that relate to or would result in, among other things: (a) acquiring additional securities, alone or together with any other person, which would result in the holder beneficially owning or controlling, or being deemed to beneficially own or control, over 9.99% of our total outstanding common stock or other voting securities, (b) an extraordinary corporate transaction such as a merger, (c) a sale of a material amount of our assets, (d) any change in our present board of directors or management, (e) any change in our present capitalization or dividend policy, or (f) any other material change in our business or corporate structure; or (3) requesting that we or our directors, officers, employees, agents or representatives amend or waive any such covenants. The holder is not a registered broker-dealer or an affiliate of a registered broker-dealer. For a description of our relationship with Optimus, please see, “Management’s Discussion and Analysis and Results of Operations — Liquidity and Capital Resources,” “Description of Our Capital Stock — Preferred Stock” and “Description of Our Capital Stock — Warrants.”

Excludes warrants to purchase 50,038 shares of our common stock which we issued to Optimus CG II, Ltd. on July 19, 2010 and which, pursuant to the terms of the amendment to the Series B purchase agreement dated as of April 4, 2011, will automatically be cancelled effective as of the effective date of this registration statement.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Our policy is to enter into transactions with related parties on terms that, on the whole, are no more favorable, or no less favorable, than those available from unaffiliated third parties. Based on our experience in the business sectors in which we operate and the terms of our transactions with unaffiliated third parties, we believe that all of the transactions described below met this policy standard at the time they occurred.

On September 22, 2008, we entered into a note purchase agreement with our Chief Executive Officer, Thomas A. Moore, pursuant to which we agreed to sell to Mr. Moore, from time to time, one or more senior promissory notes, which we refer to as the Moore Notes. On June 15, 2009, we amended the terms of the Moore Notes to increase the amounts available from $800,000 to $950,000 and to change the maturity date of the Moore Notes from June 15, 2009 to the earlier of January 1, 2010 or our next equity financing resulting in gross proceeds to us of at least $6.0 million. On February 15, 2010, we agreed to amend the terms of the Moore Notes such that (i) Mr. Moore had the option to elect to receive accumulated interest thereon on or after March 17, 2010 (which amounted to approximately $130,000), (ii) we were to begin to make monthly installment payments of $100,000 on the outstanding principal amount on April 15, 2010; provided, however, that the balance of the principal will be repaid in full on consummation of our next equity financing resulting in gross proceeds to us of at least $6.0 million and (iii) we will retain $200,000 of the repayment amount for investment in our next equity financing. In May 2010, we issued 1,176,471 shares of common stock to Mr. Moore (based on a price of $0.17 per share) in satisfaction of $200,000 of Moore Notes.

In connection with a loan made by Mr. Moore to us in the amount of $230,000, we agreed to further amend and restate the terms of the Moore Notes on March 17, 2011 to increase the principal amount due by $230,000. Under the terms of the amended and restated Moore Notes: (i) the maturity date is the earlier of (x) the date of consummation of an equity financing by us in an amount of $6.0 million or more and (y) the occurrence of any event of default as defined in the Moore Notes, (ii) Mr. Moore may elect, at his option, to receive accumulated interest thereon on or after April 15, 2011 (which we expect will amount to approximately $91,000), (iii) we will make monthly installment payments of $100,000 on the outstanding principal amount beginning on June 15, 2011, and (iv) we may retain, at the option of Mr. Moore, $200,000 of the repayment amount for investment in our next equity financing. In addition, Mr. Moore made a loan to us in the amount of $65,000 in April 2011. As of June 20, 2011, approximately $873,000 in principal amount of Moore Notes were outstanding and payable to Mr. Moore.

The Moore Notes bear interest at a rate of 12% per annum, compounded quarterly, and may be prepaid in whole or in part at our option without penalty at any time prior to maturity. In consideration of Mr. Moore’s original agreement to purchase the Moore Notes, we agreed that concurrently with an equity financing resulting in gross proceeds to us of at least $6.0 million, we will issue to Mr. Moore a warrant to purchase our common stock, which will entitle Mr. Moore to purchase a number of shares of our common stock equal to one share per $1.00 invested by Mr. Moore in the purchase of the Moore Notes. The terms of these warrants were subsequently modified by our board of directors based on the terms of the senior bridge financing increasing the number of shares underlying the warrant from one share per $1.00 invested to two and one-half shares. The terms of these warrants were further modified by our board of directors to increase the number of shares underlying the warrant from two and one-half shares per $1.00 invested to three shares. The final terms are anticipated to contain the same terms and conditions as warrants issued to investors in the subsequent financing (which are currently exercisable at $0.15 per share).

DESCRIPTION OF OUR CAPITAL STOCK

General

At the date hereof, we are authorized by our articles of incorporation to issue an aggregate of 500,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of “blank check” preferred stock, par value $0.001 per share. As of June 20, 2011, there were 230,083,519 shares of common stock, no shares of Series A preferred stock and 740 shares of Series B preferred stock outstanding.

Common Stock

Holders of our common stock are entitled to one vote for each share held of record on each matter submitted to a vote of stockholders. Holders of our common stock do not have cumulative voting rights, which means that the holders of more than one half of the outstanding shares of common stock, subject to the rights of the holders of the preferred stock, if any, can elect all of our directors, if they choose to do so. In this event, the holders of the remaining shares of common stock would not be able to elect any directors. Except as otherwise required by Delaware law, and subject to the rights of the holders of preferred stock, if any, all stockholder action is taken by the vote of a majority of the outstanding shares of common stock voting as a single class present at a meeting of stockholders at which a quorum consisting of a majority of the outstanding shares of common stock is present in person or proxy.

Subject to the prior rights of any class or series of preferred stock which may from time to time be outstanding, if any, holders of our common stock are entitled to receive ratably, dividends when, as, and if declared by our board of directors out of funds legally available for that purpose and, upon our liquidation, dissolution, or winding up, are entitled to share ratably in all assets remaining after payment of liabilities and payment of accrued dividends and liquidation preferences on the preferred stock, if any. Holders of our common stock have no preemptive rights and have no rights to convert their common stock into any other securities. The outstanding common stock is validly authorized and issued, fully-paid and nonassessable.

Common Stock in this Offering

The 25,560,000 shares of common stock offered in this prospectus when issued and paid for in accordance with the terms of the warrants will be fully paid and are not liable for further call or assessment.

Preferred Stock

General

We are authorized to issue up to 5,000,000 shares of “blank check” preferred stock. Preferred stock may be issued in one or more series and having the rights, privileges and limitations, including voting rights, conversion privileges and redemption rights, as may, from time to time, be determined by our board of directors. Preferred stock may be issued in the future in connection with acquisitions, financings, or other matters as our board of directors deems appropriate. In the event that any shares of preferred stock are to be issued, a certificate of designation containing the rights, privileges and limitations of such series of preferred stock will be filed with the Secretary of State of the State of Delaware. The effect of such preferred stock is that, subject to Federal securities laws and Delaware law, our board of directors alone, may be able to authorize the issuance of preferred stock which could have the effect of delaying, deferring, or preventing a change in control of us without further action by the stockholders, and may adversely affect the voting and other rights of the holders of our common stock. The issuance of preferred stock with voting and conversion rights may also adversely affect the voting power of holders of our common stock, including the loss of voting control to others.

Our board of directors has authorized the issuance of up to 1,000 shares of Series A Preferred Stock, $0.001 par value per share, none of which are outstanding as of the date hereof, and up to 2,500 shares of Series B Preferred Stock, $0.001 par value per share, 740 shares of which are outstanding as of the date hereof.

On July 19, 2010, we issued 500 shares of Series B preferred stock to Optimus, which we refer to as the Series B exchange shares, in exchange for the 500 shares of Series A preferred stock so that all shares of our preferred stock held or subsequently purchased by Optimus under the Series B purchase agreement, as amended, would be redeemable upon substantially identical terms. Any accrued and unpaid dividends on the Series A preferred stock were deemed cancelled and such amount of accrued and unpaid dividends were reflected as accrued and unpaid dividends of the Series B preferred stock issued to Optimus.

Subject to satisfaction of certain closing conditions, Optimus is obligated to purchase such shares of Series B preferred stock on the 10th trading day after the date of the notice. We will determine, in our sole discretion, the timing and amount of Series B preferred stock to be purchased by Optimus, and may sell such shares in multiple tranches. Optimus will not be obligated to purchase the Series B preferred stock upon our notice (i) in the event the average closing sale price of our common stock during the nine trading days following delivery of our notice falls below 75% of the closing sale price of our common stock on the trading day prior to the date such notice is delivered to Optimus, or (ii) to the extent such purchase would result in Optimus and its affiliates beneficially owning more than 9.99% of our outstanding common stock.

Redemption of Series B Preferred Stock

Rights to Issue Additional Series B Preferred Stock

We encourage you to read the forms of each warrant attached as exhibits to this registration statement.

Warrants - 2007 Private Placement

As part of the October 17, 2007 private placement, investors were issued units consisting of one share of common stock and ¾ of a five-year warrant to purchase one share of common stock at an exercise price of $0.20 per share (prior to anti-dilution adjustments). The October 2007 warrants provide for adjustment of their exercise prices upon the occurrence of certain events, such as payment of a stock dividend, a stock split, a reverse split, a reclassification of shares, or any subsequent equity sale, rights offering, pro rata distribution (full ratchet), or any fundamental transaction such as a merger, sale of all of its assets, tender offer or exchange offer, or reclassification of its common stock. If at any time after October 17, 2008 there is no effective registration statement registering, or no current prospectus available for, the resale of the shares underlying the warrants by the holder of such warrants, then the warrants may also be exercised at such time by means of a “cashless exercise.” The October 2007 warrants provide that they may not be exercised if, following the exercise, the holder will be deemed to be the beneficial owner of more than 9.99% of our outstanding shares of common stock.

Warrants - Series A Preferred Stock Offering

At the time of the execution of the Series A purchase agreement, an affiliate of Optimus was granted on September 24, 2009 a warrant to purchase up to 33,750,000 shares of our common stock at an exercise price of $0.20 to be adjusted in connection with the draw down of each tranche. As permitted by the terms of such warrant, the aggregate exercise price of $6,250,970 received by us as of June 20, 2011 is payable pursuant to four year full recourse promissory notes each bearing interest at the rate of 2% per year. In addition, in connection with the draw down of the final tranche, we issued an additional warrant to an affiliate of Optimus to purchase up to 2,818,000 shares of common stock at an exercise price of $0.18 per share. As permitted by the terms of such warrant, the aggregate exercise price of $507,240 received by us as of June 20, 2011 is payable pursuant to a four year full recourse promissory note bearing interest at the rate of 2% per year. The foregoing promissory notes are not due or payable at any time that (a) we are in default of under the Series A purchase agreement, any loan agreement or other material agreement or (b) there are any Series B exchange shares issued or outstanding.

Warrants - Series B Preferred Stock Offering

At the time of execution of the Series B purchase agreement, we issued to Optimus a three-year warrant to purchase up to 40,500,000 shares of our common stock, at an initial exercise price of $0.25 per share, of which 50,038 shares of our common stock remain available to purchase. As permitted by the terms of this warrant, the aggregate exercise price of $6,291,000 received by us as of June 20, 2011 are payable pursuant to four year full recourse promissory notes bearing interest at the rate of 2% per year. On December 30, 2010, certain of these promissory notes in the aggregate amount of $3,064,382 were cancelled as part of the redemptions price in connection with our redemption of 226 shares of Series B Preferred Stock held by Optimus. As of June 20, 2011 we have issued to Optimus warrants to purchase an aggregate of 77,068,000 shares of our common stock of which the above referenced 50,038 remain outstanding. Pursuant to the terms of the amendment to the Series B purchase agreement dated as of April 4, 2011, this warrant will automatically be cancelled effective as of the effective date of this registration statement.

On April 4, 2011, in connection with the amendment to the Series B purchase agreement, we issued an additional warrant to an affiliate of Optimus to purchase up to 25,560,000 shares of common stock at an initial exercise price of $0.15 per share. The warrant will become exercisable on the earlier of (i) the date on which a registration statement registering for resale the shares of our common stock issuable upon exercise of the warrant becomes effective and (ii) the first date on which such warrant shares are eligible for resale without limitation under Rule 144 (assuming a cashless exercise of the warrant). The warrant consists of and is exercisable in tranches, with a separate tranche being created upon each delivery of a tranche notice under the Series B purchase agreement, as amended. On each tranche notice date, that portion of the warrant equal to 135% of the tranche amount will vest and become exercisable, and such vested portion may be exercised at any time during the exercise period on or after such tranche notice date. On each tranche notice date, the exercise price of the warrant will be adjusted to the closing sale price of a share of our common stock on the applicable tranche notice date. The exercise price of the warrant may be paid (at the option of the affiliate of Optimus) in cash or by issuance of a four-year, full-recourse promissory note, bearing interest at 2% per annum, and secured by a specified portfolio of assets. However, such promissory note is not due or payable at any time that (a) we are in default of any preferred stock purchase agreement for Series B preferred stock or any warrant issued pursuant thereto, any loan agreement or other material agreement or (b) there are any shares of the Series B preferred stock issued or outstanding. The warrant also provides for cashless exercise in certain circumstances. If Optimus fails to acquire and pay for the Series B preferred stock upon delivery of our notice in accordance with the terms of the Series B purchase agreement, as amended, (assuming the timely and full satisfaction of all of the conditions set forth therein) and the warrant has not previously been exercised in full, we have the right to demand surrender of the warrant (or any remaining portion thereof) without compensation, and the warrant will automatically be cancelled.

In return for extending the maturity dates of certain senior bridge notes, we issued additional warrants to purchase an aggregate of 1,450,663 shares of our common stock with terms similar to their original warrants. Due to the anti-dilution provisions contained in our warrant agreements, we issued an aggregate of 3,556,285 additional warrants as a result of “ratchets” that occurred in January 2010 and September 2010. In December 2010, we issued an aggregate of 815,790 additional warrants to certain of our junior bridge note holders, with terms similar to their original warrants, and new promissory notes in the aggregate principal amount of $343,000 in return for extending the maturity dates of their original promissory notes. The senior bridge warrants and junior bridge warrants provide for adjustment of their exercise prices upon the occurrence of certain events, such as payment of a stock dividend, a stock split, a reverse split, a reclassification of shares, or any subsequent equity sale, rights offering, pro rata distribution (full ratchet), or any fundamental transaction such as a merger, sale of all of its assets, tender offer or exchange offer, or reclassification of its common stock. Each of the senior bridge warrants and some of the junior bridge warrants may be exercised on a cashless basis under certain circumstances. Each of the senior bridge warrants and junior bridge warrants provide that they may not be exercised if, following the exercise, the holder will be deemed to be the beneficial owner of more than 9.99% of our outstanding shares of common stock.

The May 2011 warrants may be exercised on a cashless basis under certain circumstances. The May 2011 warrants include a limitation on conversion or exercise, which provides that at no time will an investor be entitled to exercise any number of May 2011 warrants that would result in the beneficial ownership by the investor and its affiliates of more than 4.99% of the outstanding shares of our common stock on such date.

Antidilution Adjustments

As a result of anti-dilution protection provisions contained in certain of our outstanding warrants (including the October 2007 warrants, the senior bridge warrants and the junior bridge warrants), we have (i) reduced the exercise price from $0.20 (prior to anti-dilution adjustments) per share to $0.15, per share with respect to an aggregate of approximately 77.0 million warrant shares to purchase our common stock and (ii) correspondingly adjusted the amount of warrant shares issuable pursuant to certain warrants such that approximately 10.4 million additional warrant shares are issuable at $0.15 per share.

We encourage you to read the registration rights agreements attached as exhibits to this registration statement.

Registration Rights - 2007 Private Placement

In connection with our October 2007 private placement, we entered into a registration rights agreement with the investors in that offering pursuant to which we agreed to file a registration statement with the SEC within 45 days after the final closing of the offering covering all of the shares of common stock sold to the investors in the October 2007 private placement and all of the shares of common stock underlying the warrants that were sold to the investors in that offering. Accordingly, we initially filed a registration statement on Form SB-2 with the SEC on November 30, 2007 to register all of such shares of common stock. The Form SB-2 registration statement was declared effective by the SEC on January 22, 2008. Under the terms of the registration rights agreement, we agreed to keep the registration statement effective until the earlier of (i) the date on which all of those shares of common stock may be resold without registration under the Securities Act without regard to any volume limitations under Rule 144 under the Securities Act or (ii) the date on which all of those shares of common stock have been resold pursuant to the registration statement or Rule 144 under the Securities Act.

The registration rights agreement provides that if, among other things, the registration statement ceases for any reason to remain continuously effective, or the selling stockholders are otherwise not permitted to use it to resell their shares of common stock for more than 10 consecutive calendar days or more than a total of twenty calendar days (which need not be consecutive calendar days) during any 12-month period, then we are required to pay as partial liquidated damages an amount equal to 1.5% of the aggregate purchase price paid by any selling stockholder for such common stock, up to a maximum of 15% of such purchase price. If we fail to pay any required partial liquidated damages in full within seven days after the date payable, we are then required to pay interest thereon at a rate of 15% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the selling stockholder, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full.

We filed a post-effective amendment on Form S-1 to our original registration statement on Form SB-2 to, among other things, update the information included in the original registration statement, convert the original registration statement to a registration statement on Form S-1, and to deregister shares of our common stock which were covered by the original registration statement, but are no longer required to be registered under the terms of our registration rights agreement.

Pursuant to the terms of the Series B purchase agreement, as amended, our rights to deliver a notice to Optimus requiring Optimus to acquire and pay for the Series B preferred stock are subject to having a current, valid and effective registration statement covering the resale of all shares underlying the warrants unless all shares underlying the warrants are eligible for resale without limitation under Rule 144 (assuming cashless exercise of the warrant).

In order to induce Optimus to enter into the Series B purchase agreement, our executive officers, directors and beneficial owners of 10% or more of our common stock agreed that, for a period of ten trading days beginning on each date we deliver a notice exercising the put described in the Series B purchase agreement, as amended, to Optimus and ending on the closing date of the put exercise, they will not, without the prior written consent of Optimus, (a) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position with respect to, any of our common stock or any securities convertible into or exercisable or exchangeable for our common stock, or warrants or other rights to purchase our common stock or any such securities, or any securities substantially similar to our common stock, (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our common stock or any securities convertible into or exercisable or exchangeable for our common stock or any such securities, or warrants or other rights to purchase our common stock, whether any such transaction is to be settled by delivery of our common stock or such other securities, in cash or otherwise or (c) publicly announce an intention to effect any transaction specified in clause (a) or (b).

PLAN OF DISTRIBUTION

Each selling stockholder of our common stock and any of their donees, pledgees, transferees, assignees and other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock on the OTC Bulletin Board or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

an exchange distribution in accordance with the rules of the applicable exchange;

privately negotiated transactions;

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

broker-dealers may agree with the selling stockholder to sell a specified number of such shares at a stipulated price per share;

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

a combination of any such methods of sale; or

any other method permitted pursuant to applicable law.

The selling stockholder may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by any selling stockholder may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA NASD Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

In connection with the sale of our common stock or interests therein, the selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of our common stock in the course of hedging the positions they assume. The selling stockholder may also sell shares of our common stock short and deliver these securities to close out their short positions and to return borrowed shares in connection with such short sales, or loan or pledge our common stock to broker-dealers that in turn may sell these securities. The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholder and any underwriters, broker-dealers or agents that participate in the sale of our common stock or interests therein will be considered “underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales and, as such, any discounts, commissions, concessions or profit they earn on any resale of the shares may be deemed to be underwriting discounts and commissions under the Securities Act. Since the selling stockholder is deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act, it will be subject to the prospectus delivery requirements of the Securities Act. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholder against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

The selling stockholder is subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than this prospectus. There is no underwriter or coordinating broker-dealer acting in connection with the proposed sale of the resale shares by the selling stockholder.

The resale shares will be sold only through registered or licensed broker-dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. As of the date of this prospectus, we have not filed for registration or qualification in any state.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to our common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of our common stock by the selling stockholder or any other person. We will make copies of this prospectus available to the selling stockholder and have informed it of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

LEGAL MATTERS

The validity of the shares of common stock offered by the selling stockholder will be passed upon for us by our counsel, Greenberg Traurig, LLP, New York, New York. A shareholder of Greenberg Traurig, LLP owns 3,333,334 shares of our common stock, warrants to purchase 4,083,335 shares of our common stock and convertible promissory notes convertible into 1,500,000 shares of our common stock.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

Advaxis, Inc.

North Brunswick, New Jersey

We have audited the accompanying balance sheets of Advaxis, Inc. as of October 31, 2010 and 2009, and the related statements of operations, stockholders' equity (deficiency), and cash flows for the years then ended and for the cumulative period from March 1, 2002 (inception) to October 31, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Advaxis, Inc. as of October 31, 2010 and 2009, and the results of its operations and its cash flows for the years then ended and the cumulative period from March 1, 2002 (inception) to October 31, 2010 in conformity with U.S. generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company’s products are being developed and have not generated significant revenues. As a result, the Company has suffered recurring losses and its liabilities exceed its assets. This raises substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

ADVAXIS, INC.

(a development stage company)

NOTES TO FINANCIAL STATEMENTS

1. PRINCIPAL BUSINESS ACTIVITY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Advaxis, Inc. (the "Company") was incorporated in 2002 and is a biotechnology company researching and developing new cancer-fighting techniques. The Company is in the development stage and its operations are subject to all of the risks inherent in an emerging business enterprise.

The preparation of financial statements in accordance with GAAP involves the use of estimates and assumptions that affect the recorded amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ substantially from these estimates. Significant estimates include the fair value and recoverability of the carrying value of intangible assets (patents and licenses) the fair value of options, the fair value of embedded conversion features, warrants, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates.

The Company’s products are being developed and have not generated significant revenues. As a result, the Company has suffered recurring losses and its liabilities exceed its assets which raises substantial doubt about our ability to continue as a going concern. These losses are expected to continue for an extended period of time. The Company intends to continue raising funds through the sale of both debt and equity in order to continue funding ongoing clinical trials activity. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. There is a working capital deficiency and recurring losses that raise substantial doubt about its ability to continue as a going concern. The financial statement does not include any adjustments to the carrying amount and classification of recorded assets and liabilities should we be unable to continue operations.

Revenue from license fees and grants is recognized when the following criteria are met; persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable, and collectability is reasonably assured. In licensing arrangements, delivery does not occur for revenue recognition purposes until the license term begins. Nonrefundable upfront fees received in exchange for products delivered or services performed that do not represent the culmination of a separate earnings process will be deferred and recognized over the term of the agreement using the straight line method or another method if it better represents the timing and pattern of performance. Since its inception and through October 31, 2010 all of the Company’s revenues have been from grants. For the years ended October 31, 2010 and 2009, all of the Company’s revenues were received from multiple grants.

For revenue contracts that contain multiple elements, revenue arrangements with multiple deliverables are divided into separate units of accounting if the delivered item has value to the customer on a standalone basis and there is objective and reliable evidence of the fair value of the undelivered item.

The Company maintains its cash in bank deposit accounts (money market) that at times exceed federally insured limits.

Equipment is stated at cost. Depreciation and amortization are provided for on a straight-line basis over the estimated useful life of the asset ranging from 3 to 5 years. Expenditures for maintenance and repairs that do not materially extend the useful lives of the respective assets are charged to expense as incurred. The cost and accumulated depreciation and/or amortization of assets retired or sold are removed from the respective accounts and any gain or loss is recognized in operations.

Intangible assets, which consist primarily of legal and filing costs in obtaining patents and licenses and are being amortized on a straight-line basis over 20 years.

We review our long-lived assets for impairment whenever events and circumstances indicate that the carrying value of an asset might not be recoverable and its carrying amount exceeds its fair value, which is based upon estimated undiscounted future cash flows. Net assets recorded on the balance sheet for patents and licenses related to ADXS11-001, ADXS31-142, ADXS31-164 and other products are in development. However, if a competitor were to gain FDA approval for a treatment before us or if future clinical trials fail to meet the targeted endpoints, we would likely record an impairment related to these assets. In addition, if an application is rejected or fails to be issued we would record an impairment of its estimated book value.

F-9

Net Loss Per Share

Basic net income or basic net loss per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the periods. Diluted earnings per share give effect to dilutive options, warrants, convertible debt and other potential common stock outstanding during the period. Therefore, in the case of a net loss the impact of the potential common stock resulting from warrants, outstanding stock options and convertible debt are not included in the computation of diluted loss per share, as the effect would be anti-dilutive. In the case of net income the impact of the potential common stock resulting from these instruments that have intrinsic value are included in the diluted earnings per share. The table sets forth the number of potential shares of common stock that have been excluded from diluted net loss per share. The warrants (excluding approximately 15.8 million warrants held by an affiliate of Optimus (as defined below) include anti-dilutive provisions to adjust the number and price of the warrants based on certain types of equity transactions.

	As of October 31,
	2010		2009
Warrants		103,139,628		127,456,301
Stock Options		26,467,424		7,881,591
Convertible Debt (using the if-converted method)		4,358,176		49,749,280
Total		133,965,228		185,087,172

Income Taxes

Deferred income taxes are provided for the differences between the bases of assets and liabilities for financial reporting and income tax purposes. Future ownership changes may limit the future utilization of these net operating loss and research and development tax credit carry-forwards as defined by the Internal Revenue Code. The amount of any potential limitation is unknown. The net deferred tax asset has been fully offset by a valuation allowance due to our history of taxable losses and uncertainty regarding our ability to generate sufficient taxable income in the future to utilize these deferred tax assets.

Accounts payable consists entirely of trade accounts payable

Research and Development Expenses

Research and development expenses include, but are not limited to, payroll and personnel expenses, lab expenses, clinical trial and related clinical manufacturing costs, facilities and related overhead costs.

Accounting for Stock-Based Compensation

Stock-based compensation is estimated at the grant date based on the award’s fair value as calculated by the Black-Scholes-Merton option-pricing model (hereinafter referred to as the “BSM model”) and is recognized as expense over the requisite service period. The BSM model requires various assumptions including volatility, forfeiture rates and expected option life. If any of the assumptions used in the BSM model change significantly, stock-based compensation expense may differ materially in the future from that recorded in the current period. See Note 5 for information on stock-based compensation expense incurred in the years ending October 31, 2010 and 2009.

Warrant Liability/Embedded Derivative Liability

The Company has outstanding Warrants and convertible features (Embedded Derivatives) in its outstanding Senior and Junior Subordinated Promissory Notes. We refer to all Senior Convertible Promissory Notes and Junior Subordinated Convertible Promissory Notes as “Bridge Notes”. The Warrants and Embedded Derivatives are recorded at their relative fair values at issuance and will continue to be recorded at fair value each subsequent balance sheet date. Any change in value between reporting periods will be recorded at each reporting date. Both derivatives will continue to be reported until such time as they are exercised, expire, or mature at which time these derivatives will be adjusted to fair value and reclassified from liabilities to equity.

In April 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2010-17, Revenue Recognition—Milestone Method (Topic 605) - Milestone Method of Revenue Recognition - a consensus of the FASB Emerging Issues Task Force . This ASU provides guidance to vendors on the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. This guidance is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. The Company has not yet begun to generate revenues that contain milestone payments, as it is still a pre-revenue, development stage company. ASU 2010-17 will be reviewed and implemented, if applicable to the company’s revenue arrangements, in the fiscal year in which the company begins to generate revenues.

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

F-10

2. SHARE-BASED COMPENSATION EXPENSE

The Company adopted ASC 718 and uses the modified prospective transition method, which requires the application of the accounting standard as of November 1, 2005, the first day of the Company’s fiscal year 2006. In accordance with the modified prospective transition method, the Company’s Financial Statements for prior periods were not restated to reflect, and do not include the impact of ASC 718. The Company began recognizing expense in an amount equal to the fair value of share-based payments (stock option awards) on their date of grant, over the requisite service period of the awards (usually the vesting period). Under the modified prospective method, compensation expense for the Company is recognized for all share based payments granted and vested on or after November 1, 2005 and all awards granted to employees prior to November 1, 2005 that were unvested on that date but vested in the period over the requisite service periods in the Company’s Statement of Operations. Prior to the adoption of the fair value method, the Company accounted for stock-based compensation to employees under the intrinsic value method of accounting set forth in Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees , and related interpretations. Therefore, compensation expense related to employee stock options was not reflected in operating expenses in any period prior to the fiscal year of 2006 and prior period results have not been restated. Since the date of inception to October 31, 2005 had the Company adopted the fair value based method of accounting for stock-based employee compensation under the provisions of ASC 718, Stock Compensation expense would have totaled $328,176 and the effect on the Company’s net loss would have been as follows for the period March 1, 2002 (date of inception) to October 31, 2010:

	March 1, 2002 (date of inception) to October 31, 2010
Net Loss as reported	$	(27,372,116	)
Add: Stock based option expense included in recorded net loss		89,217
Deduct stock option compensation expense determined under fair value based method		(328,176	)
Adjusted Net Loss	$	(27,611,075	)

The fair value of each option granted from the Company’s stock option plans during the years ended October 31, 2010 and 2009 was estimated on the date of grant using the Black-Scholes option-pricing model. Using this model, fair value is calculated based on assumptions with respect to (i) expected volatility of the Company’s Common Stock price, (ii) the periods of time over which employees and Board Directors are expected to hold their options prior to exercise (expected lives), (iii) expected dividend yield on the Company’s Common Stock, and (iv) risk-free interest rates, which are based on quoted U.S. Treasury rates for securities with maturities approximating the options’ expected lives. The company used their own historical volatility in determining the volatility to be used. Expected lives are based on contractual terms given the early stage of the business and lack of intrinsic value. The expected dividend yield is zero as the Company has never paid dividends to common shareholders and does not currently anticipate paying any in the foreseeable future.

	Year Ended			Year Ended
	October 31, 2010			October 31, 2009
Expected volatility		156.5	%		170.2	%
Expected Life	10.0 years			6.0 years
Dividend yield		0			0
Risk-free interest rate		2.75	%		3.5	%

Stock-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that vested during the period. Stock-based compensation expense for the twelve months ended October 31, 2010 includes compensation expense for share-based payment awards granted prior to, but not yet vested as of October 31, 2005 based on the grant date fair value and compensation expense for the share-based payment awards granted subsequent to October 31, 2005 based on the grant date fair value estimated in accordance with the provisions of ASC 718. Compensation expense for all share-based payment awards to be recognized using the straight line method over the requisite service period. As stock-based compensation expense for the fiscal years 2010 and 2009 is based on awards granted and vested, it has been reduced for estimated forfeitures (4.4%). ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Company’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred.

The Company accounts for nonemployee stock-based awards in which goods or services are the consideration received for the equity instruments issued based on the fair value of the equity instruments.

F-11

3. INTANGIBLE ASSETS

Intangible assets primarily consist of legal and filing costs associated with obtaining patents and licenses. The license and patent costs capitalized primarily represent the value assigned to the Company’s 20-year exclusive worldwide license agreement with Penn which are amortized on a straight-line basis over their remaining useful lives which are estimated to be twenty years from the effective date of Penn Agreement dated July 1, 2002. The value of the license and patents are based on management’s assessment regarding the ultimate recoverability of the amounts paid and the potential for alternative future uses. This license now includes the exclusive right to exploit 32 patents issued and 33 patents pending and applied for in most of the largest markets in the world.

As of October 31, 2010, all gross capitalized costs associated with the licenses and patents filed and granted as well as costs associated with patents pending are $2,506,347 as shown under license and patents on the table below. The expirations of the existing patents range from 2014 to 2023 but the expirations can be extended based on market approval if granted and/or based on existing laws and regulations. Capitalized costs associated with patent applications that are abandoned without future value are charged to expense when the determination is made not to pursue the application. No other patent applications with future value were abandoned and charged to expense in the current or prior year. Amortization expense for licensed technology and capitalized patent cost is included in general and administrative expenses.

Under the amended and restated agreement we are billed actual patent expenses as they are passed through from Penn and or billed directly from our patent attorney. The following is a summary of intangible assets as of the end of the following fiscal periods:

	October 31, 2010			October 31, 2009
License	$	651,992		$	571,275
Patents		1,854,355			1,080,299
Total intangibles		2,506,347			1,651,574
Accumulated Amortization		(380,356	)		(279,936	)
Intangible Assets	$	2,125,991		$	1,371,638

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An asset is considered to be impaired when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition exceeds its carrying amount. The amount of impairment loss, if any, is measured as the difference between the net book value of the asset and its estimated fair value.

4. ACCRUED EXPENSES:

The following table represents the major components of accrued expenses:

	October 31, 2010		October 31, 2009
Salaries and other compensation	$	500,927	$	768,552

5. NOTES PAYABLE:

Moore Notes

On September 22, 2008, Advaxis entered into an agreement (the “Moore Agreement”) with the Company’s Chief Executive Officer, Thomas Moore, pursuant to which the Company agreed to sell senior promissory notes to Mr. Moore, from time to time (“the Moore Notes”). On June 15, 2009, Mr. Moore and the Company amended the Moore Notes to increase the amounts available pursuant to the Moore Agreement from $800,000 to $950,000 and changed the maturity date of the Moore Notes from June 15, 2009 to the earlier of (i) default under the terms of the Moore Agreement or (ii) the Company’s next equity financing resulting in gross proceeds to the Company of at least $6 million. The Moore Agreement was amended per the terms of the June 18, 2009 Note Purchase Agreement (described below) retroactively to include the same warrant provision provided to investors purchasing notes under the Note Purchase Agreement.

F-12

On February 15, 2010, we agreed to amend the terms of the Moore Notes such that (i) Mr. Moore may elect, at his option, to receive accumulated interest thereon on or after March 17, 2010, (ii) we would begin to make monthly installment payments of $100,000 on the outstanding principal amount beginning on April 15, 2010; provided, however, that the balance of the principal will be repaid in full on consummation of our next equity financing resulting in gross proceeds to us of at least $6.0 million and (iii) we would retain $200,000 of the repayment amount for investment in our next equity financing.

The Company issued 1,176,471 shares in satisfaction of $200,000 of the aggregate principal amount outstanding under the Moore Notes. For the twelve months ending October 31,2010, the Company paid Mr. Moore $250,000 in principal and $130,000 in interest. As of October 31, 2010, the Company was not in default under the terms of the Moore Agreement.

Senior Convertible Promissory Notes

Effective June 18, 2009, the Company entered into a Note Purchase Agreement with certain accredited investors, pursuant to which such investors acquired senior convertible promissory notes of the Company in the aggregate principal face amount of $1,131,353, for an aggregate net purchase price of $961,650. At October 31, 2010, the Company had repaid $1,042,529 of these notes and $88,824 in principal value remained outstanding.

Junior Subordinated Convertible Promissory Notes

Additionally, during October 2009, the company entered into Bridge Note agreements whereby certain accredited investors acquired junior subordinated convertible promissory in the aggregate face amounts of approximately $2.1 million for aggregate net purchase prices of approximately $1.8 million. As of October 31, 2010, all of these October 2009 Bridge Notes had been repaid or converted into the Company’s common stock as described below.

During the year ended October 31, 2010, we issued to certain accredited investors (i) junior unsecured convertible promissory notes in the aggregate principal face amount of approximately $1,462,000 for an aggregate net purchase price of approximately $1,255,000 and (ii) warrants to purchase 3,270,955 shares of our common stock at original exercise prices ranging from $0.17 to $0.25 per share, subject to adjustments upon the occurrence of certain events. As a result of the latest round of equity financing with Optimus in September 2010, under the Series B Preferred Stock Purchase Agreement (see Note 11 – Shareholders’ Equity), the Company issued an additional 616,136 warrants to these bridge note holders due to a decrease in the exercise price of their warrants, to $0.15 per share. The company recognized non-cash warrant expense in the income statement for all additional warrants issued to bridge note holders as a result of the above equity financing (See Note 6 for additional information). The bridge notes were issued with original issue discounts ranging from 6% to 18% and are convertible into shares of our common stock. These notes mature on or before May 31, 2011.

During the twelve months ended October 31, 2010, the company repaid a total of approximately $1,542,000 in principal value and converted $2,420,000 in principal value into 14,237,489 shares of our common stock. At October 31, 2010, approximately $777,000 in principal value remains and is classified as a current liability on the balance sheet. The indebtedness represented by these bridge notes is expressly subordinate to our currently outstanding senior secured indebtedness (approximately $89,000 at October 31, 2010).

As of October 31, 2010, all Bridge Notes were originally issued with an original issue discounts ranging from 6% to 18%. Each Investor paid between $0.82 and $.94 for each $1.00 of principal amount of notes purchased at the closing. The bridge notes are convertible into shares of the Company’s common stock at an exercise price contingent on the completion of an equity financing. As a result of the latest round of equity financing with Optimus in September 2010, under the Series B Preferred Stock Purchase Agreement (see Note 11 – Shareholders’ Equity), all the outstanding bridge notes, at October 31, 2010, are convertible into shares of the Company’s common stock at an exercise price of $0.15 per share. For every dollar invested, each Investor received warrants to purchase 2 ½ shares of common stock (the “Bridge Warrants”) subject to adjustments upon the occurrence of certain events as more particularly described below and in the form of Warrant. As of October 31, 2010 all Bridge Note warrants have an exercise price of $.15 per share. The Bridge Notes may be prepaid in whole or in part at the option of the Company without penalty at any time prior to the Maturity Date. The warrants may be exercised on a cashless basis under certain circumstances.

During November 2009, the Company paid $14,788 in full payment of the November 13, 2003 note and BioAdvance agreed to extend the remaining note. During the twelve months ending October 31, 2010, the Company paid $10,000 in accrued interest on the remaining note. As of October 31, 2010, the Company owes approximately $40,000 in principal and $11,000 in interest to BioAdvance.

Warrants

As of October 31, 2010, there were outstanding warrants to purchase 103,139,628 shares of our common stock with exercise prices ranging from $0.15 to $0.287 per share. Information on the outstanding warrants is as follows:

(1) For purposes of this warrant, exercise price means an amount per warrant share equal to the closing sale price of a share of common stock on the applicable tranche notice date.

Warrant Liability/Embedded Derivative Liability

The fair value of the Warrants and Embedded Derivatives are estimated using the BSM model. The fair value of the Warrants and Embedded Derivatives are estimated using an adjusted BSM model. The Company computes valuations, each quarter, using the BSM model for each derivative instrument to account for the various possibilities that could occur due to changes in the inputs to the BSM model as a result of contractually-obligated changes (for example, changes in strike price to account for down-round provisions). The Company effectively weights each calculation based on the likelihood of occurrence to determine the value of the derivative at the reporting date. As of October 31, 2010, the fair value of the Warrants and Embedded Derivatives were determined to be approximately $13.0 million and $81,000, respectively. As of October 31, 2009, the fair value of the Warrants and Embedded Derivatives were determined to be approximately $12.0 million and $1.0 million, respectively We increased income approximately $446,000 for net changes in the fair value of the common stock warrant liability and embedded derivative liability for year ending October 31, 2010. We increased income approximately $5.8 million for net changes in the fair value of the common stock warrant liability and embedded derivative liability for year ending October 31, 2009.

The repricing (“ratchet effect”) of our warrants both in January and September 2010 also increased the company’s warrant liability for the year ending October 31, 2010. As a result of the increase in warrant liability due to the ratchet effect, the company issued approximately 21.8 million additional warrants to existing warrant holders. These warrants were recorded at their fair values at issuance and will continue to be recorded at fair value each subsequent balance sheet date. Any change in value between reporting periods will be recorded at each reporting date. These warrants will continue to be reported until such time as they are exercised, expire, or mature at which time these derivatives will be adjusted to fair value and reclassified from liabilities to equity. Of the total 21.8 million additional warrants, approximately 3.6 million warrants were issued to bridge note holders. The company recognized non-cash warrant expense of approximately $206,000, for the year ending October 31, 2010, related to the fair value of the additional warrants issued to bridge note holders because they were not contractually obligated (no anti-dilution provisions in their warrant agreements) to receive additional warrants due to ratchet effects.

7. STOCK OPTIONS:

2004 Stock Option Plan

In November 2004, our board of directors adopted and stockholders approved the 2004 Stock Option Plan (“2004 Plan”). The 2004 Plan provides for the grant of options to purchase up to 2,381,525 shares of our common stock to employees, officers, directors and consultants. Options may be either “incentive stock options” or non-qualified options under the Federal tax laws. Incentive stock options may be granted only to our employees, while non-qualified options may be issued, in addition to employees, to non-employee directors, and consultants. Except as determined by the Administrator at the time of the grant of the Options, a participant Options vest over four years, twenty-five percent of the granted amount on or after the first year anniversary of the date of the granting of an Options and the balance to vest an additional one twelfth of the Options granted for each additional three-month period following the first anniversary over a next three years.

The 2004 Plan is administered by “disinterested members” of the board of directors or the Compensation Committee, who determine, among other things, the individuals who shall receive options, the time period during which the options may be partially or fully exercised, the number of shares of common stock issuable upon the exercise of each option and the option exercise price.

Subject to a number of exceptions, the exercise price per share of common stock subject to an incentive option may not be less than the fair market price value per share of common stock on the date the option is granted. The per share exercise price of the common stock subject to a non-qualified option may be established by the board of directors, but shall not, however, be less than 85% of the fair market value per share of common stock on the date the option is granted. The aggregate fair market value of common stock for which any person may be granted incentive stock options which first become exercisable in any calendar year may not exceed $100,000 on the date of grant.

We must grant options under the 2004 Plan within ten years from the effective date of the 2004 Plan. The effective date of the Plan was November 12, 2004. Subject to a number of exceptions, holders of incentive stock options granted under the Plan cannot exercise these options more than ten years from the date of grant. Options granted under the 2004 Plan generally provide for the payment of the exercise price in cash and may provide for the payment of the exercise price by delivery to us of shares of common stock already owned by the optionee having a fair market value equal to the exercise price of the options being exercised, or by a combination of these methods. Therefore, if it is provided in an optionee’s options, the optionee may be able to tender shares of common stock to purchase additional shares of common stock and may theoretically exercise all of his stock options with no additional investment other than the purchase of his original shares. As of October 31, 2010, 2,319,025 options were granted under the 2004 plan.

2005 Stock Option Plan

In June 2006, our board of directors adopted and stockholders approved on June 6, 2006, the 2005 Stock Option Plan (“2005 Plan”).

The 2005 Plan provides for the grant of options to purchase up to 5,600,000 shares of our common stock to employees, officers, directors and consultants. Options may be either “incentive stock options” or non-qualified options under the Federal tax laws. Incentive stock options may be granted only to our employees, while non-qualified options may be issued to non-employee directors, consultants and others, as well as to our employees.

The 2005 Plan is administered by “disinterested members” of the board of directors or the compensation committee, who determine, among other things, the individuals who shall receive options, the time period during which the options may be partially or fully exercised, the number of shares of common stock issuable upon the exercise of each option and the option exercise price.

Subject to a number of exceptions, the exercise price per share of common stock subject to an incentive option may not be less than the fair market value per share of common stock on the date the option is granted. The per share exercise price of the common stock subject to a non-qualified option may be established by the board of directors, but shall not, however, be less than 85% of the fair market value per share of common stock on the date the option is granted. The aggregate fair market value of common stock for which any person may be granted incentive stock options which first become exercisable in any calendar year may not exceed $100,000 on the date of grant.

We must grant options under the 2005 Plan within ten years from the effective date of the 2005 Plan. The effective date of the Plan was January 1, 2005. Subject to a number of exceptions, holders of incentive stock options granted under the 2005 Plan cannot exercise these options more than ten years from the date of grant. Options granted under the 2005 Plan generally provide for the payment of the exercise price in cash and may provide for the payment of the exercise price by delivery to us of shares of common stock already owned by the optionee having a fair market value equal to the exercise price of the options being exercised, or by a combination of these methods. Therefore, if it is provided in an optionee’s options, the optionee may be able to tender shares of common stock to purchase additional shares of common stock and may theoretically exercise all of his stock options with no additional investment other than the purchase of his original shares. As of October 31, 2010 there were 4,983,667 options granted under the 2005 plan.

On November 12, 2004, in connection with the recapitalization,(see Note 10), the options granted under the 2002 option plan were canceled, and employees and consultants were granted options of Advaxis under the 2004 plan. The cancellation and replacement had no accounting consequence since the aggregate intrinsic value of the options immediately after the cancellation and replacement was not greater than the aggregate intrinsic value immediately before the cancellation and replacement, and the ratio of the exercise price per share to the fair value per share was not reduced. Additionally, the original options were not modified to accelerate vesting or extend the life of the new options. The table provided in this Note 7 reflects the options on a post recapitalization basis.

2009 Stock Option Plan

Our board of directors adopted the 2009 Stock Option Plan (the “2009 Plan”), effective July 21, 2009, and was approved by our shareholders in June 2010. An aggregate of 20,000,000 shares (subject to adjustment by the compensation committee) are reserved for issuance upon the exercise of options granted under the plan. As of October 31, 2010, options to purchase 19,209,732 shares of our common stock have been granted under the 2009 Plan. The purpose of this plan is to, among other things, (i) comply with certain exclusions from the limitations of Section 162(m) of the Internal Revenue Code of 1986, which we refer to as the Code, and (ii) comply with the incentive stock options rules under Section 422 of the Code. The maximum number of shares of common stock to which options may be granted to any one individual under the 2009 Plan is 6,000,000 (subject to adjustment by the compensation committee).

A summary of the grants, cancellations and expirations (none were exercised) of the Company’s outstanding options for the periods starting with October 31, 2008 through October 31, 2010 is as follows:

Under the terms of the agreement, Mr. Moore was entitled to receive a base salary of $250,000 per year, subject to increase to $350,000 per year, his current salary, upon our successful raise of at least $4.0 million (which condition was satisfied on November 1, 2007) and subject to annual review for increases by our board of directors in its sole discretion. The agreement also provides that Mr. Moore is entitled to receive family health insurance at no cost to him. Mr. Moore’s employment agreement does not provide for the payment of a bonus.

In connection with our hiring of Mr. Moore, we agreed to grant Mr. Moore up to 1,500,000 shares of our common stock, of which 750,000 shares were issuable on November 1, 2007 upon our successful raise of $4.0 million and 750,000 shares are issuable upon our successful raise of an additional $6.0 million (which condition was satisfied in January 2010 and the shares were then issued in June 2010).

Each option is exercisable at $0.143 per share (which was equal to the closing sale price of our common stock on December 15, 2006) and expires on December 15, 2016. The options vest in 24 equal monthly installments. On July 21, 2009, we granted Mr. Moore options to purchase 2,500,000 shares of our common stock. Each option is exercisable at $0.10 per share (which was equal to the closing sale price of our common stock on July 21, 2009) and expires on July 21, 2019. One-third of these options vested on the grant date, and the remaining vest in one third installments on the first and second anniversary of the grant.

Pursuant to the terms of his employment agreement, all options will be awarded and vested upon a merger of the company which is a change of control or a sale of the company while Mr. Moore is employed. In addition, if Mr. Moore’s employment is terminated by us, Mr. Moore is entitled to receive severance payments equal to one year’s salary at the then current compensation level.

Rothman Employment Agreement and Option Agreements. We previously entered into an employment agreement with Dr. Rothman, Ph.D., dated as of March 7, 2005, that provided that he would serve as our Vice President of Clinical Development for an initial term of one year.

9. INCOME TAXES:

The Company has a net operating loss carry forward of approximately $20,095,366 and $19,466,268 at October 31, 2010 and 2009, respectively, available to offset taxable income through 2030. Due to change in control provisions, the Company’s utilization of these losses may be limited. The tax effects of loss carry forwards give rise to a deferred tax asset and a related valuation allowance at October 31, as follows:

		2010			2009
Net operating loss carryforwards-federal	$	8,038,146		$	7,786,507

In a letter dated November 13, 2008 from the New Jersey Economic Development Authority we were notified that our application for the New Jersey Technology Tax Certificate Transfer Program was preliminarily approved. Under the State of New Jersey NOL Transfer Program for small business we received a net cash amount of $922,020 on December 12, 2008 from the sale of our State Net Operating Losses (“NOL”) through December 31, 2007 of $1,084,729. In January 2010, the company received a net cash amount of $278,978 from the sale of some of our State Net Operating Losses (“NOL”) through December 31, 2008. The company plans to sell its Net Operating Losses and research tax credits for the 2009 fiscal year under the same State of New Jersey Program for small business.

We adopted ASC 740, Income Taxes, formerly Financial Interpretation Number 48, “Accounting for Uncertain Tax Positions” (“FIN 48”) on November 1, 2007. ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109,” Accounting for Income Taxes.” ASC 740 prescribes a recognition threshold and measurement of a tax position taken or expected to be taken in a tax return. We did not establish any additional reserves for uncertain tax liabilities upon adoption of ASC 740. There were no adjustments for uncertain tax positions in the current year.

We will account for interest and penalties related to uncertain tax positions, if any, as part of our provision for federal and state income taxes.

We do not expect that the amounts of unrecognized benefits will change significantly within the next 12 months.

We are no longer subject to audit under the statute of limitations by the Internal Revenue Service and state jurisdictions for 2006 through 2009.

10. CAPITALIZATION

On November 12, 2004, Great Expectations and Associates, Inc. ("Great Expectations") acquired the Company through a share exchange and reorganization (the "Recapitalization"), pursuant to which the Company became a wholly owned subsidiary of Great Expectations. Great Expectations acquired (i) all of the issued and outstanding shares of common stock of the Company and the Series A preferred stock of the Company in exchange for an aggregate of 15,597,723 shares of authorized, but theretofore unissued, shares of common stock, no par value, of Great Expectations;. Prior to the closing of the Recapitalization, Great Expectations performed a 200-for-1 reverse stock split, thus reducing the issued and outstanding shares of common stock of Great Expectations from 150,520,000 shares to 752,600 shares. Additionally, 752,600 shares of common stock of Great Expectations were issued to the financial advisor in connection with the Recapitalization. Accordingly, the transaction is treated as a recapitalization, rather than a business combination. The historical financial statements of Advaxis are now the historical financial statements of the Company. Historical shareholders' equity (deficiency) of Advaxis has been restated to reflect the recapitalization, and include the shares received in the transaction.

F-20

On November 12, 2004, the Company completed an initial closing of a private placement offering (the “Private Placement”), whereby it sold an aggregate of $2.925 million worth of units to accredited investors. Each unit was sold for $25,000 (the “Unit Price”) and consisted of (a) 87,108 shares of common stock and (b) a warrant to purchase, at any time prior to the fifth anniversary following the date of issuance of the warrant, to purchase 87,108 shares of common stock included at a price equal to $0.40 per share of common stock (a “Unit”). In consideration of the investment, the Company granted to each investor certain registration rights and anti-dilution rights. Also, in November 2004, the Company converted approximately $618,000 of aggregate principal promissory notes and accrued interest outstanding into Units.

On December 8, 2004, the Company completed a second closing of the Private Placement, whereby it sold an aggregate of $200,000 of Units to accredited investors.

On January 4, 2005, the Company completed a third and final closing of the Private Placement, whereby it sold an aggregate of $128,000 of Units to accredited investors.

Pursuant to the terms of a investment banking agreement, dated March 19, 2004, by and between the Company and Sunrise Securities, Corp. (the “Placement Agent”), the Company issued to the Placement Agent and its designees an aggregate of 2,283,445 shares of common stock and warrants to purchase up to an aggregate of 2,666,900 shares of common stock. The shares were issued as part consideration for the services of the Placement Agent, as placement agent for the Company in the Private Placement. In addition, the Company paid the Placement Agent a total cash fee of $50,530.

On January 12, 2005, the Company completed a second private placement offering whereby it sold an aggregate of $1,100,000 of units to a single investor. As with the Private Placement, each unit issued and sold in this subsequent private placement was sold at $25,000 per unit and is comprised of (i) 87,108 shares of common stock, and (ii) a five-year warrant to purchase 87,108 shares of our common stock at an exercise price of $0.40 per share. Upon the closing of this second private placement offering the Company issued to the investor 3,832,753 shares of common stock and warrants to purchase up to an aggregate of 3,832,753 shares of common stock.

The aggregate sale from the four private placements was $4,353,000, which was netted against transaction costs of $329,673 for net proceeds of $4,023,327.

Pursuant to a Securities Purchase Agreement dated February 2, 2006 ($1,500,000 principal amount) and March 8, 2006 ($1,500,000 principal amount) we issued to Cornell Capital Partners, LP (“Cornell”) $3,000,000 principal amount of the Company’s Secured Convertible Debentures due February 1, 2009 (the “Debentures”) at face amount, and five year Warrants to purchase 4,200,000 shares of Common Stock at the price of $0.287 per share and five year B Warrants to purchase 300,000 shares of Common Stock at a price of $0.3444 per share.

The Debentures were convertible at a price equal to the lesser of (i) $0.287 per share (“Fixed Conversion Price”), or (ii) 95% of the lowest volume weighted average price of the Common Stock on the market on which the shares are listed or traded during the 30 trading days immediately preceding the date of conversion (“Market Conversion Price”). Interest was payable at maturity at the rate of 6% per annum in cash or shares of Common Stock valued at the conversion price then in effect.

Cornell agreed that (i) it would not convert the Debenture or exercise the Warrants if the effect of such conversion or exercise would result in its and its affiliates’ holdings of more than 4.9% of the outstanding shares of Common Stock, (ii) neither it nor its affiliates will maintain a short position or effect short sales of the Common Stock while the Debentures are outstanding, and (iii) no more than $300,000 principal amount of the Debenture could be converted at the Market Conversion Price during a calendar month.

On August 24, 2007, we issued and sold an aggregate of $600,000 principal amount promissory notes bearing interest at a rate of 12% per annum and warrants to purchase an aggregate of 150,000 shares of our common stock to three investors including Thomas Moore, our Chief Executive Officer. Mr. Moore invested $400,000 and received warrants for the purchase of 100,000 shares of Common Stock. The promissory note and accrued but unpaid interest thereon are convertible at the option of the holder into shares of our common stock upon the closing by the Company of a sale of its equity securities aggregating $3,000,000 or more in gross proceeds to the Company at a conversion rate which shall be the greater of a price at which such equity securities were sold or the price per share of the last reported trade of our common stock on the market on which the common stock is then listed, as quoted by Bloomberg LP. At any time prior to conversion, we have the right to prepay the promissory notes and accrued but unpaid interest thereon. Mr. Moore converted his $400,000 bridge investment into 2,666,667 shares of common stock and 2,000,000 $0.20 Warrants based on the terms of the Private Placement. He was paid $7,101 interest in cash.

F-21

On October 17, 2007, pursuant to a Securities Purchase Agreement, we completed a private placement resulting in $7,384,235.10 in gross proceeds, pursuant to which we sold 49,228,334 shares of common stock at a purchase price of $0.15 per share solely to institutional and accredited investors. Each investor received a five-year warrant to purchase an amount of shares of common stock that equals 75% of the number of shares of common stock purchased by such investor in the offering.

Concurrent with the closing of the private placement, the Company sold for $1,996,700 to CAMOFI Master LDC and CAMHZN Master LDC, affiliates of its financial advisor, Centrecourt Asset Management (“Centrecourt”), an aggregate of (i) 10,000,000 shares of Common Stock, (ii) 10,000,000 warrants exercisable at $0.20 (prior to anti-dilution adjustments) per share, and (iii) 5-year warrants to purchase an additional 3,333,333 shares of Common Stock at a purchase price of $0.001 per share (the “$0.001 Warrants”). The Company and the two purchasers agreed that the purchasers would be bound by and entitled to the benefits of the Securities Purchase Agreement as if they had been signatories thereto. The $0.20 (prior to anti-dilution adjustments) Warrants and $0.001 Warrants contain the same terms, except for the exercise price. Both warrants provide that they may not be exercised if, following the exercise, the holder will be deemed to be the beneficial owner of more than 9.99% of the Company’s outstanding shares of Common Stock. Pursuant to a consulting agreement dated August 1, 2007 with Centrecourt with respect to the anticipated financing, in which Centrecourt was engaged to act as the Company’s financial advisor, Registrant paid Centrecourt $328,000 in cash and issued 2,483,333 warrants exercisable at $0.20 (prior to anti-dilution adjustments) per share to Centrecourt, which Centrecourt assigned to the two affiliates.

All of the $0.20 (prior to anti-dilution adjustments) Warrants and $0.001 Warrants provide for adjustment of their exercise prices upon the occurrence of certain events, such as payment of a stock dividend, a stock split, a reverse split, a reclassification of shares, or any subsequent equity sale, rights offering, pro rata distribution, or any fundamental transaction such as a merger, sale of all of its assets, tender offer or exchange offer, or reclassification of its common stock. If at any time after October 17, 2008 there is no effective registration statement registering, or no current prospectus available for, the resale of the shares underlying the warrants by the holder of such warrants, then the warrants may also be exercised at such time by means of a “cashless exercise.”

In connection with the private placement, we entered into a registration rights agreement with the purchasers of the securities pursuant to which we agreed to file a registration statement with the Securities and Exchange Commission with an effectiveness date within 90 days after the final closing of the offering. The registration statement was declared effective on January 22, 2008.

At the closing of this private placement, we exercised our right under an agreement dated August 23, 2007 with YA Global Investments, L.P. f/k/a Cornell Capital Partners, L.P. (“Yorkville”), to redeem the outstanding $1,700,000 principal amount of our Secured Convertible Debentures due February 1, 2009 owned by Yorkville, and to acquire from Yorkville warrants expiring February 1, 2011 to purchase an aggregate of 4,500,000 shares of our common stock. We paid an aggregate of (i) $2,289,999 to redeem the debentures at the principal amount plus a 20% premium and accrued and unpaid interest, and (ii) $600,000 to repurchase the warrants.

On September 22, 2008, Advaxis, Inc. (the “Company”) entered into a Note Purchase Agreement (the “Agreement”) with the Company’s Chief Executive Officer, Thomas Moore, pursuant to which the Company agreed to sell to Mr. Moore, from time to time, one or more senior promissory notes (each a “Note” and collectively the “Notes”) with an aggregate principal amount of up to $800,000.

The Agreement was reviewed and recommended to the Company’s Board of Directors (the “Board”) by a special committee of the Board and was approved by a majority of the disinterested members of the Board. The Note or Notes, if and when issued, will bear interest at a rate of 12% per annum, compounded quarterly, and will be due and payable on (i) the earlier of the close of the Company’s next equity financing resulting in gross proceeds to the Company of at least $6,000,000 (the “Subsequent Equity Raise”) or (ii) default under the terms of the Moore Agreement (the “Maturity Date”). The Note(s) may be prepaid in whole or in part at the option of the Company without penalty or any time prior to the Maturity Date.

In consideration of Mr. Moore’s agreement to purchase the Notes, the Company agreed that concurrently with the Subsequent Equity Raise, the Company will issue to Mr. Moore a warrant to purchase the Company’s common stock, which will entitle Mr. Moore to purchase a number of shares of the Company’s common stock equal to one share per $1.00 invested by Mr. Moore in the purchase of one or more Notes. Such warrant would contain the same terms and conditions as warrants issued to investors in the Subsequent Equity Raise. At October 31, 2010, with the agreement of Mr. Moore, the company had not issued these warrants to him.

11. SHAREHOLDERS’ EQUITY :

Series A Preferred Stock Equity Financing

For the twelve months ended October 31, 2010, the Company issued and sold 500 shares of nonconvertible, redeemable Series A Preferred Stock (“Series A Preferred Stock”) to Optimus Life Sciences Capital Partners LLC (“the Investor”) pursuant to the terms of a Preferred Stock Purchase Agreement between the Company and the Investor dated September 24, 2009 (the “Series A Purchase Agreement”). The aggregate purchase price for the shares of Series A Preferred Stock was $5,000,000 (of which the Company received approximately $4,488,000, net of registration statement costs, commitment and legal fees of approximately $512,000). No more shares of Series A Preferred Stock remain available under the Series A Purchase Agreement.

F-22

In connection with the issuance by the Company of Series A Preferred Stock, described above, an affiliate of the Investor exercised warrants to purchase 36,568,000 shares of the Company’s common stock at exercise prices ranging from $0.17 to $0.20 per share. The Company, the affiliate and the Investor also agreed to waive certain terms and conditions in the Series A Purchase Agreement and such warrants in order to permit the affiliate of the Investor to exercise such warrants and acquire beneficial ownership of more than 4.99% of the Company’s common stock on the date of exercise. As permitted by the terms of such warrants, the aggregate exercise price of approximately $6,758,000 to be received by the Company is payable pursuant to 4 year full recourse promissory notes bearing interest at the rate of 2% per annum.

Series B Preferred Stock Financing

On July 19, 2010, the Company entered into a Series B Preferred Stock Purchase Agreement with Optimus (the “Series B Purchase Agreement”), pursuant to which the Investor agreed to purchase, upon the terms and subject to the conditions set forth therein and described below, up to $7.5 million of the Company’s newly authorized, non-convertible, redeemable Series B preferred stock (“Series B Preferred Stock”) at a price of $10,000 per share. Under the terms of the Series B Purchase Agreement, and after the SEC has declared effective a registration statement relating to the Warrant Shares (as defined below), the Company may from time to time until July 19, 2013, present Optimus with a notice to purchase a specified amount of Series B Preferred Stock. Subject to satisfaction of certain closing conditions, the Investor is obligated to purchase such shares of Series B Preferred Stock on the 10th trading day after the date of the notice. The Company will determine, in its sole discretion, the timing and amount of Series B Preferred Stock to be purchased by the Investor, and may sell such shares in multiple tranches. The Investor will not be obligated to purchase the Series B Preferred Stock upon the Company’s notice (i) in the event the average closing sale price of the Company’s common stock during the nine trading days following delivery of such notice falls below 75% of the closing sale price of the Company’s common stock on the trading day prior to the date such notice is delivered to the Investor, or (ii) to the extent such purchase would result in the Company and its affiliates beneficially owning more than 9.99% of the Company’s outstanding common stock.

On July 19, 2010, the Company issued 500 shares of Series B Preferred Stock to the Investor (“Series B Exchange Shares”) in exchange for the 500 shares of Series A Preferred Stock issued under the Series A Purchase Agreement so that all shares of the Company’s preferred stock held or subsequently purchased by the Investor under the Series B Purchase Agreement would be redeemable upon substantially identical terms.

Pursuant to the Series B Purchase Agreement, on July 19, 2010, the Company issued to an affiliate of the Investor a three-year warrant to purchase up to 40,500,000 shares of the Company’s common stock (the “Warrant Shares”), at an initial exercise price of $0.25 per share, subject to adjustment as described below. The warrant will become exercisable on the earlier of (i) the date on which a registration statement registering for resale the shares of common stock issuable upon exercise of the warrant becomes effective and (ii) the first date on which such Warrant shares are eligible for resale without limitation under Rule 144 (assuming a cashless exercise of the warrant). The warrant consists of and is exercisable in tranches, with a separate tranche being created upon each delivery of a tranche notice under the Series B Purchase Agreement. On each tranche notice date, that portion of the warrant equal to 135% of the tranche amount will vest and become exercisable, and such vested portion may be exercised at any time during the exercise period on or after such tranche notice date. On and after the first tranche notice date and each subsequent tranche notice date, the exercise price of the warrant will be adjusted to the closing sale price of a share of the Company’s common stock on the applicable tranche notice date. The exercise price of the warrant may be paid (at the option of the affiliate of the Investor) in cash or by its issuance of a four-year, full-recourse promissory note, bearing interest at 2% per annum, and secured by a specified portfolio of assets. However, such promissory note is not due or payable at any time that (a) the Company is in default of any preferred stock purchase agreement for Series B Preferred Stock or any warrant issued pursuant thereto, any loan agreement or other material agreement or (b) there are any shares of the Series B Preferred Stock issued or outstanding.

For the period between July 19, 2010 and October 31, 2010 the Company issued and sold 289 shares of nonconvertible, redeemable Series B Preferred Stock (“Series B Preferred Stock”) to Optimus Life Sciences Capital Partners LLC (“the Investor”) pursuant to the terms of the Series B Agreement between the Company and the Investor dated July 19, 2010. The aggregate purchase price for the shares of Series B Preferred Stock was $2,890,000 (of which the company received $2,545,000, net of commitment and legal fees of $345,000).

In connection with the issuance by the Company of the Series B Preferred Stock described above, an affiliate of the Investor exercised warrants to purchase 24,697,059 shares of the Company’s common stock at exercise prices ranging from $0.15 to $0.17 per share. The Company, the affiliate and the Investor also agreed to waive certain terms and conditions in the Series B Purchase Agreement and such warrants in order to permit the affiliate of the Investor to exercise such warrants and acquire beneficial ownership of more than 4.99% of the Company’s common stock on the date of exercise. As permitted by the terms of such warrants, the aggregate purchase price of approximately $3,901,500 received by the Company is payable pursuant to four year, full recourse promissory notes bearing interest at the rate of 2% per annum.

F-23

On September 28, 2010, Advaxis, Inc. (the “ Company ”) issued and sold 165 shares of Series B preferred stock (part of the 289 preferred shares sold between July 19, 2010 and October 31, 2010) to Optimus pursuant to the terms of the Series B Purchase Agreement. The aggregate purchase price for the shares of Series B Preferred Stock was $1.65 million (of which the Company received $1.505 million. The Company has agreed to pay a fee of $140,000 to the Investor in consideration of (i) the closing of the purchase of the Series B Preferred Stock taking place prior to 10 trading days following the delivery of the tranche notice as required by the Purchase Agreement, (ii) the Investor allowing the Company to increase the amount of the original tranche notice after it was originally delivered to the Investor and (iii) the waiver by the Investor of a closing condition under the Purchase Agreement. As of September 28, 2010, 461 shares of Series B Preferred Stock remained available for sale under the Series B Purchase Agreement.

In connection with the September 28, 2010 issuance by the Company of the Series B Preferred Stock described above, an affiliate of Optimus exercised a warrant to purchase 14,850,000 shares of the Company’s common stock at an exercise price of $0.15 per share. As permitted by the terms of these warrants, the aggregate exercise price of approximately $2,227,500 received by the Company is payable pursuant to four-year full recourse promissory notes bearing interest at the rate of 2% per year.

Warrants

Almost all of our warrants (except the warrants issued to an affiliate of Optimus) contain “full-ratchet” anti-dilution provisions originally set at $0.20 with a term of five years. The Optimus exercise of warrants on January 11, 2010 triggered the anti dilution provisions of the warrant agreements requiring a reset of both the price of these warrants (from $.20 to $.17) and an increase in amount of warrants. Subsequently, the Optimus exercise of warrants on September 28, 2010 triggered the anti-dilution provisions of the warrant agreements requiring a reset of both the price of these warrants (from $0.17 to $0.15) and an increase in the amount of warrants. Therefore, any future financial offering or instrument issuance below $0.15 per share of the Company’s common stock or warrants (subject to certain exceptions) will cause further anti-dilution and/or repricing provisions in the above mentioned 87.4 million outstanding warrants (see table in Note 5). During September 2010, the company issued additional warrants to bridge note holders to mirror the “ratchet effect” warrants and repricing of the 2007 Private Placement transaction. In September 2010, the company issued approximately 1.9 million of such warrants to bridge note holders, valued using the BSM model, at approximately, $206,000.

12. Fair Value

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance describes a fair value hierarchy based on the levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1 — Quoted prices in active markets for identical assets or liabilities

Level 2— Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or corroborated by observable market data or substantially the full term of the assets or liabilities

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the value of the assets or liabilities

In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, the following table represents the Company’s fair value hierarchy for its financial liabilities measured at fair value on a recurring basis as of October 31, 2010:

	Level 2
	2010

Fair Value of Embedded Derivative	$	81,028

Common Stock Warrants		13,006,194

Total	$	13,087,222

F-24

The derivative instruments were valued using the market approach, which is considered Level 2 because it uses inputs other than quoted prices in active markets that are either directly or indirectly observable. Accordingly, the derivatives were valued using the Black-Scholes model as described in Note 6.

13. SUBSEQUENT EVENTS

NOTES TO THE FINANCIAL STATEMENTS

(unaudited)

1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Nature of Operations

Advaxis, Inc. (the “Company”) is a development stage biotechnology company with the intent to develop safe and effective cancer vaccines that utilize multiple mechanisms of immunity. The Company is developing a live Listeria vaccine technology under license from the University of Pennsylvania (“Penn”) which secretes a protein sequence containing a tumor-specific antigen. The Company believes this vaccine technology is capable of stimulating the body’s immune system to process and recognize the antigen as if it were foreign, generating an immune response able to attack the cancer. The Company believes this to be a broadly enabling platform technology that can be applied to the treatment of many types of cancers, infectious diseases and auto-immune disorders.

This technology involves the creation of genetically engineered Listeria that stimulate the innate immune system and induce an antigen-specific immune response involving both arms of the adaptive immune system. In addition, this technology supports, among other things, the immune response by altering tumors to make them more susceptible to immune attack, stimulating the development of specific blood cells that underlie a strong therapeutic immune response.

Since the Company’s inception in 2002, it has focused its initial development efforts upon therapeutic cancer vaccines targeting cervical cancer, its predecessor condition, cervical intraepithelial neoplasia, head and neck cancer, breast cancer, prostate cancer, and other cancers. Although no products have been commercialized to date, research and development and investment continues to be placed behind the pipeline and the advancement of this technology. Pipeline development and the further exploration of the technology for advancement entail risk and expense. It is anticipated that ongoing operational costs for the Company will continue to increase significantly due to several ongoing clinical trials that began this fiscal year.

Basis of Presentation

The accompanying unaudited interim financial statements include all adjustments (consisting only of those of a normal recurring nature) necessary for a fair statement of the results of the interim period. The October 31, 2010 balance sheet is derived from the audited balance sheet included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2010 (the “Form 10-K’). These interim financial statements should be read in conjunction with the Company’s financial statements and notes for the fiscal year ended October 31, 2010 included in the Form 10-K. The Company believes these financial statements reflect all adjustments (consisting only of normal, recurring adjustments) that are necessary for a fair presentation of its financial position and results of operations for the periods presented. Management’s plans are to continue to raise additional funds through the sales of debt or equity securities. Results of operations for the interim periods presented are not necessarily indicative of results to be expected for the year.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. There is a working capital deficiency, a shareholders’ deficiency and recurring losses from operations that raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments to the carrying amount and classification of recorded assets and liabilities should the Company be unable to continue operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles required management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the differences could be material. The most significant estimates impact the following transactions or account balances: stock compensation, liabilities (including the embedded derivative liability), warrant valuation, impairment of intangibles, fixed assets and projected operating results.

F-30

Net Loss Per Share

Basic net income or basic net loss per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the periods. Diluted earnings per share give effect to dilutive options, warrants, convertible debt and other potential common stock outstanding during the period. Therefore, in the case of a net loss the impact of the potential common stock resulting from warrants, outstanding stock options and convertible debt are not included in the computation of diluted loss per share, as the effect would be anti-dilutive. In the case of net income the impact of the potential common stock resulting from these instruments that have intrinsic value are included in the diluted earnings per share. The table sets forth the number of potential shares of common stock that have been excluded from diluted net loss per share. Approximately 83.7 million warrants (excluding approximately 25.6 million warrants held by an affiliate of Optimus) include anti-dilutive provisions to adjust the number and price of the warrants based on certain types of equity transactions.

Accounting for Stock-Based Compensation

Warrant Liability/Embedded Derivative Liability

The Company has outstanding Warrants and convertible features (Embedded Derivatives) in its outstanding Senior and Junior Subordinated Promissory Notes. In addition, the Company has an outstanding convertible feature (Embedded Derivative) on its long-term convertible promissory notes with an accredited investor. The Warrants and Embedded Derivatives are recorded at their relative fair values at issuance and will continue to be recorded at fair value each subsequent balance sheet date. Any change in value between reporting periods will be recorded at each reporting date. Both derivatives will continue to be reported until such time as they are exercised, expire, or mature at which time these derivatives will be adjusted to fair value and reclassified from liabilities to equity.

Income Tax Benefit

On February 4, 2011, the Company received a net cash amount of $379,472 from the sale of our 2008 and 2009 State Net Operating Losses (“NOL”) under the State of New Jersey Program for small business.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

3. INTANGIBLE ASSETS

As of April 30, 2011, all gross capitalized costs associated with the licenses and patents filed and granted as well as costs associated with patents pending are $2,697,442 as shown under license and patents on the table below. The expirations of the existing patents range from 2014 to 2023 but the expirations can be extended based on market approval if granted and/or based on existing laws and regulations.

Senior Convertible Promissory Notes

Effective June 18, 2009, the Company entered into a Note Purchase Agreement with certain accredited investors, pursuant to which such investors acquired senior convertible promissory notes of the Company. At April 30, 2011, the Company had one outstanding senior convertible promissory note with $88,824 in principal value and $26,471 in accrued interest remaining. In May 2011, the Company received a notice of intent to convert the principal and accrued interest on this outstanding senior convertible promissory note into shares of the Company’s common stock (See Subsequent Events Note #8).

Junior Subordinated Convertible Promissory Notes

During the three months ended April 30, 2011 the Company entered into Junior Subordinated Convertible Promissory Notes in the aggregate principal value of $473,392 for an aggregate net purchase price of $430,000. These notes had maturity dates ranging from May 2, 2011 to October 31, 2011.

The Company has repaid approximately $160,000 in principal and interest during the current period. As of April 30, 2011, the Company had approximately $2,216,000 in outstanding junior subordinated convertible promissory notes with Original Issue Discount (“OID”) amounts ranging from 5% to 18% and with maturity dates ranging from July 30, 2010 to October 31, 2011.

In May 2011, the Company converted or had investors agree to convert approximately $1,167,000 of principal and interest on these outstanding junior subordinated convertible promissory notes into shares of the Company’s common stock. In addition, the Company also reached agreements with four investors, whose notes were to mature on or around April 30, 2011, in the aggregate principal value of approximately $153,000 (included in the above aggregate principal value of $2,216,000) to exchange their original notes for new notes, in the aggregate principal amount of approximately $161,000, with a maturity date due on or around August 2, 2011. In return for exchanging their notes, these investors received additional interest of $8,033 in total. (See Subsequent Events Note #8)

We refer to all Senior Convertible Promissory Notes and Junior Subordinated Convertible Promissory Notes as “Bridge Notes”.

The Bridge Notes are convertible into shares of the Company’s common stock at an exercise price contingent on the completion of an equity financing. For every dollar invested in our Bridge Notes, each Investor received warrants to purchase between 1½ and 2 ½ shares of common stock (the “Bridge Warrants”) subject to adjustments upon the occurrence of certain events as more particularly described below and in the form of Warrant. As of April 30, 2011, substantially all of the Bridge Warrants have an exercise price of $.15 per share. The Bridge Notes may be prepaid in whole or in part at the option of the Company without penalty at any time prior to the Maturity Date. The warrants may be exercised on a cashless basis under certain circumstances.

Long-term Convertible Promissory Notes

On April 28, 2011, Advaxis, Inc. issued and sold to an accredited investor a convertible promissory note of the Company (“Long-term Convertible Promissory Notes”) in the aggregate principal amount of $500,000 (together with the related ancillary documents, the “ A-Note ”) in return for the payment in cash from the Investor of $500,000. The A-Note bears interest in the form of a one time interest charge of 8% of the principal amount of the A-Note, payable with the A-Note’s aggregate principal amount outstanding on the maturity date, April 28, 2014. The A-Note is convertible, in whole or in part, into shares of the Company’s common stock, $0.001 par value. at a per share conversion price equal to 80% of the average of the two lowest trade prices for the Common Stock in the 20 trading days previous to the effective date of each such conversion, subject to a conversion floor of $0.15. The A-Note may be prepaid by the Company without penalty beginning twelve months after issue date of the A-Note. To the extent the Investor does not elect to convert the A-Note as described above, the principal amount of the A-Note not so converted shall be payable in cash on the maturity date.

On April 28, 2011, the Company also issued and sold to the same accredited investor a convertible promissory note of the Company (“Long-term Convertible Promissory Notes”) in the aggregate principal amount of $800,000 (together with the related ancillary documents, the “ B-Note ” and together with the A-Note, the “ Company Notes ”). The B-Note bears interest in the form of a one time interest charge of 8% of the principal amount of the B-Note, payable with the B-Note’s aggregate principal amount outstanding on the maturity date, April 28, 2014. All or any portion of the aggregate principal and interest outstanding under the B-Note is convertible, at the option of the Investor from time to time (subject to the prior pre-payment of the such principal amount of the C-Note (as defined below) equal to the such principal amount of the B-Note subject to such conversion), into shares of Common Stock, at a per share conversion price equal to 80% of the average of the two lowest trade prices for the Common Stock in the 20 trading days previous to the effective date of each such conversion, subject to a conversion floor of $0.15.

Concurrently with the issuance of the B-Note, the Investor issued and delivered to the Company a secured and collateralized promissory note (together with the related ancillary documents, the “ C-Note ”), which served as the sole consideration paid to the Company for the Company’s issuance of the B-Note to the Investor. The C-Note was issued in the aggregate principal amount of $800,000, bears interest in the form of a one time interest charge of 8% of the principal amount of the C-Note, payable with the C-Note’s aggregate principal amount outstanding on the maturity date, April 28, 2014. The C-Note is to be secured by $800,000 of an unspecified money market fund, or other assets, having a value of at least $800,000.

Immediately after the purchase by the Investor of the B-Note for the C-Note, the Investor delivered to the Company the sum of $80,000 in cash as a pre payment on the principal amount outstanding under the C-Note. While no further mandatory principal or interest payments are due on the C-Note until its maturity date, the C-Note contemplates (but does not require) further voluntary pre payments by the Investor on the C-Note to the Company at the approximate rate of $250,000 per month, beginning seven months after the issuance of the C-Note, or commencing on or about November 28, 2011, but only provided: (i) all requests by the Investor for conversion of principal and interest on the B-Note are honored and (ii) the Common Stock issued upon such conversions of portions of the principal and interest on the B-Note may be freely resold by the Investor without the requirement of any restrictive legend pursuant to applicable securities laws, rules and regulations.

Additionally, the Investor may purchase up to an additional $2.4 million in aggregate principal amount of notes in the form of the B-Note from the Company (each, an “ Additional B-Notes”). The purchase price for each such Additional B-Note issued to the Investor will be paid by the issuance by the Investor to the Company of an additional note in the form of the C-Note (each, an “ Additional C-Note ”), with such Additional B-Notes and Additional C-Notes containing the same terms and provisions described above.

We refer to all convertible promissory notes, with a maturity date greater than one year collectively as “Long-term Convertible Promissory Notes”

Warrant Liability/Embedded Derivative Liability

The fair value of the Warrants and Embedded Derivatives are estimated using the BSM model.

The Company computes valuations, each quarter, using the BSM model for each derivative instrument to account for the various possibilities that could occur due to changes in the inputs to the BSM model as a result of contractually-obligated changes (for example, changes in strike price to account for down-round provisions). The Company effectively weights each calculation based on the likelihood of occurrence to determine the value of the derivative at the reporting date. As of April 30, 2011, the fair value of the Warrants and Embedded Derivatives were determined to be approximately $15.9 million and $1.8 million, respectively. For the three and six month periods ending April 30, 2011, respectively, we recorded expense of approximately $5.83 million and $1.99 million, respectively, for net changes in the fair value of the common stock warrant liability and embedded derivative liability.

5. ACCOUNTING FOR STOCK BASED COMPENSATION PLANS

The Company records compensation expense associated with stock options based on the estimated fair value of each option award that was granted using the Black-Scholes option valuation model.

The table below summarizes compensation expenses from share-based payment awards:

	For the three months ending April 30,
	2011		2010
Research and development	$	74,364	$	29,042
General and Administrative		105,112		61,225
Total stock compensation expense recognized	$	179,476	$	90,267

Total unrecognized estimated compensation expense related to non-vested stock options granted and outstanding as of April 30, 2011 was approximately $1.02 million which is expected to be recognized over a weighted-average period of approximately two years.

No options were exercised over the three and six month periods ended April 30, 2011. For the three and six month periods ended April 30, 2011, the Company granted 50,000 and 800,000 options, respectively, at a weighted average Black Scholes value and exercise price of approximately $0.12.

6. COMMITMENTS AND CONTINGENCIES

University of Pennsylvania

On May 10, 2010, we entered into a second amendment to the Penn license agreement pursuant to which we acquired exclusive licenses for an additional 27 patent applications related to our proprietary Listeria vaccine technology. As part of this amendment we exercised our option for the rights to seven additional patent dockets, including 23 additional patent applications, at an option exercise fee payable in the form of $35,000 in cash and $70,000 in our common stock (approximately 388,889 shares of our common stock based on a price of $0.18 per share) and agreed to pay historical patent costs incurred by the University of Pennsylvania at a cost of approximately $462,000. As of April 30, 2011, approximately $138,000 of this amount remained outstanding.

During the three months ending April 30, 2011, the Company paid $85,000 to Penn under all licensing agreements.

Other

Pursuant to a Clinical Research Service Agreement, the Company is obligated to pay Pharm–Olam International for service fees related to our Phase I clinical trial. As of April 30, 2011, the Company has an outstanding balance of $223,620 on this agreement.

On June 19, 2009 we entered into a Master Agreement and on July 8, 2009 we entered into a Project Agreement with Numoda, a leading clinical trial and logistics management company, to oversee Phase II clinical activity with ADXS11-001 for the treatment of invasive cervical cancer and CIN. Numoda will be responsible globally for integrating oversight and logistical functions with the clinical research organizations, contract laboratories, academic laboratories and statistical groups involved. The scope of this agreement covers over three years and is estimated to cost approximately $11.2 million for both trials. Per the agreement, the Company is permitted to pay a portion of outstanding charges to Numoda in the form of the Company’s common stock and during May 2010, the Company issued 3,500,000 shares of its common stock to an affiliate of Numoda in satisfaction of $595,000 in services rendered by Numoda to the Company under the Master Agreement. The Company has recorded deferred expenses on the balance sheet for this amount and amortizes this amount to expense over the life of the agreement. At April 30, 2011, there was a zero balance in deferred expenses related to the Numoda project. From inception of these agreements through April 30, 2011, the Company has paid Numoda approximately $4.54 million.

New Office & Laboratory Lease

In April 2011, the Company entered into a Sublease Agreement and relocated the current offices and laboratory to a 9,143 square foot leased facility in Princeton, NJ approximately 12 miles south of its former location. The agreement is for a period of approximately twenty months at the rate of approximately $15,600 per month plus utilities. Utility costs are estimated to be $7,200 per month and are capped at approximately $10,700 per month. The Company made an initial payment of approximately $54,000 prior to entering the new facility. As an inducement to enter into the agreement, the company will receive abatement for a specified number of months through July 31, 2011. The agreement has a termination date of November 29, 2012 and the Company is in discussions with building owner for lease terms beyond this date.

7. SHAREHOLDERS’ EQUITY

Series B Preferred Stock Financing

On July 19, 2010, the Company entered into a Series B Preferred Stock Purchase Agreement with Optimus (the “Series B Purchase Agreement”), pursuant to which Optimus agreed to purchase, upon the terms and subject to the conditions set forth therein and described below, up to $7.5 million of the Company’s newly authorized, non-convertible, redeemable Series B preferred stock (“Series B Preferred Stock”) at a price of $10,000 per share. Under the terms of the Series B Purchase Agreement, subject to the Company’s ability to maintain an effective registration statement for the Warrant Shares (as defined below), the Company may from time to time until July 19, 2013, present Optimus with a notice to purchase a specified amount of Series B Preferred Stock. Subject to satisfaction of certain closing conditions, Optimus is obligated to purchase such shares of Series B Preferred Stock on the 10th trading day after the date of the notice. The Company will determine, in its sole discretion, the timing and amount of Series B Preferred Stock to be purchased by Optimus, and may sell such shares in multiple tranches. Optimus will not be obligated to purchase the Series B Preferred Stock upon the Company’s notice (i) in the event the average closing sale price of the Company’s common stock during the nine trading days following delivery of such notice falls below 75% of the closing sale price of the Company’s common stock on the trading day prior to the date such notice is delivered to Optimus, or (ii) to the extent such purchase would result in the Company and its affiliates beneficially owning more than 9.99% of the Company’s outstanding common stock. The Series B Preferred Stock is only redeemable at the option of the Company as set forth in the Company’s Certificate of Designations of Preferences, Rights and Limitations of Series B Preferred Stock and not otherwise subject to redemption or repurchase by the Company in any circumstances.

Pursuant to the Series B Purchase Agreement, on July 19, 2010, the Company issued to an affiliate of Optimus a three-year warrant to purchase up to 40,500,000 shares of the Company’s common stock (the “Warrant Shares”), at an initial exercise price of $0.25 per share, subject to adjustment as described below. The warrant consists of and is exercisable in tranches, with a separate tranche being created upon each delivery of a tranche notice under the Series B Purchase Agreement. On each tranche notice date, that portion of the warrant equal to 135% of the tranche amount will vest and become exercisable, and such vested portion may be exercised at any time during the exercise period on or after such tranche notice date. On and after the first tranche notice date and each subsequent tranche notice date, the exercise price of the warrant will be adjusted to the closing sale price of a share of the Company’s common stock on the applicable tranche notice date. The exercise price of the warrant may be paid (at the option of the affiliate of Optimus) in cash or by its issuance of a four-year, full-recourse promissory note, bearing interest at 2% per annum, and secured by a specified portfolio of assets. However, such promissory note is not due or payable at any time that (a) the Company is in default of any preferred stock purchase agreement for Series B Preferred Stock or any warrant issued pursuant thereto, any loan agreement or other material agreement or (b) there are any shares of the Series B Preferred Stock issued or outstanding.

On March 14, 2011, Advaxis, Inc. (the “Company ”) issued and sold 44 shares of Series B preferred to Optimus pursuant to the terms of the Series B Purchase Agreement. The aggregate purchase price for the shares of Series B Preferred Stock was $440,000 (of which the Company received approximately265,000 (net of $150,000 used to repay a short-term promissory note due Optimus and $25,000 in legal and early payment fees).).

In connection with the March 14, 2011 issuance by the Company of the Series B Preferred Stock described above, an affiliate of Optimus exercised a warrant to purchase 3,960,000 shares of the Company’s common stock at an exercise price of $0.15 per share. As permitted by the terms of these warrants, the aggregate exercise price of $594,000 received by the Company is payable pursuant to four-year full recourse promissory notes bearing interest at the rate of 2% per year.

On April 4, 2011,the Company and Optimus entered into an amendment to the Preferred Stock Purchase Agreement dated July 19, 2010 between the Company and Optimus. Under the amendment Optimus remains obligated, from time to time until July 19, 2013, to purchase up to an additional 284 shares of non-convertible, redeemable Series B Preferred Stock, $0.001 par value per share (the “ Series B Preferred Stock ”) at a purchase price of $10,000 per share upon notice from the Company to the Investor, subject to the satisfaction of certain conditions set forth in the Purchase Agreement.

In order to satisfy certain conditions set forth in the Purchase Agreement that would allow the Company to require the Investor to purchase the remaining shares of Series B Preferred Stock under the Purchase Agreement, the Amendment provides that, among other things, the Company will issue to the Holder a three-year warrant (the “ Additional Warrant ”) to purchase up to an additional 25,560,000 shares of the Company’s common stock, at an initial exercise price of $0.15 per share, subject to adjustment as described below. The Additional Warrant will become exercisable on the earlier of (i) the date on which a registration statement registering for resale the shares of the Company’s common stock issuable upon exercise of the Additional Warrant (the “ Warrant Shares ”) becomes effective and (ii) the first date on which such Warrant Shares are eligible for resale without limitation under Rule 144 (assuming a cashless exercise of the Additional Warrant). The Additional Warrant consists of and is exercisable in tranches, with a separate tranche being created upon each delivery of a tranche notice under the Purchase Agreement. On each tranche notice date, that portion of the Additional Warrant equal to 135% of the tranche amount will vest and become exercisable, and such vested portion may be exercised at any time during the exercise period on or after such tranche notice date. On and after the first tranche notice date and each subsequent tranche notice date, the exercise price of the Additional Warrant will be adjusted to the closing sale price of a share of the Company’s common stock on the applicable tranche notice date. The exercise price of the Additional Warrant may be paid (at the option of the Investor) in cash or by the Investor’s issuance of a four-year, full-recourse promissory note (each, a “ Promissory Note ”), bearing interest at 2% per annum, and secured by specified portfolio of assets. However, no Promissory Note will be due or payable at any time that (a) the Company is in default of any preferred stock purchase agreement for Series B Preferred Stock or any warrant issued pursuant thereto, any loan agreement or other material agreement or (b) there are any shares of the Company’s Series B Preferred Stock issued or outstanding. The Additional Warrant also provides for cashless exercise in certain circumstances. If a “Funding Default” (as such term is defined in the Additional Warrant) occurs and the Additional Warrant has not previously been exercised in full, the Company has the right to demand surrender of the Additional Warrant (or any remaining portion thereof) without compensation, and the Additional Warrant will automatically be cancelled.

On April 4, 2011, the Company and the Holder also entered into an Amended and Restated Security Agreement to ensure that any Promissory Note issued upon exercise of the Additional Warrant will be entitled to the benefits of the security and collateral provisions of the Security Agreement dated as of July 19, 2010.

F-37

As of April 30, 2011, Optimus is committed to purchase 284 shares of Series B Preferred Stock at a gross purchase price of $2.84 million.

Warrants

During April 2011, investors in the Company exercised 2,590,530 warrants at a price of $0.15 per share, resulting in total proceeds to the Company of $388,580. These warrants were subject to anti-dilution provisions and therefore reduced the total number of outstanding warrants, subject to anti-dilution provisions, from approximately 86.3 million to 83.7 million warrants.

8. SUBSEQUENT EVENTS

May 2011 Note Financing

On May 9, 2011, we entered into a Note Purchase Agreement with certain accredited investors, whereby the Company issued to investors acquired approximately $7.1 million of our convertible promissory notes, which we refer to as the May 2011 Notes, for an aggregate purchase price of approximately $6.0 million in a private placement. The May 2011 Notes were issued with an original issue discount of 15%. Each investor paid $0.85 for each $1.00 of principal amount of May 2011 Notes purchased at the closing on May 12, 2011. The May 2011 Notes are convertible into shares of our common stock, at a per share conversion price equal to $0.15. Additionally, each investor received a warrant to purchase such number of shares of our common stock equal to 50% of such number of shares of our common stock issuable upon conversion of the May 2011 Note at an exercise price of $0.15 per share.

The May 2011 Notes mature on May 12, 2012. We may redeem the May 2011 Notes under certain circumstances. The warrants are exercisable at any time on or before May 12, 2014. The warrants may be exercised on a cashless basis under certain circumstances. To the extent an investor does not elect to convert its May 2011 Notes as described above, the principal amount not so converted on or prior to the maturity date shall be payable in cash on the maturity date.

The May 2011 Notes may be converted by the investors, at the option of such investor, in whole or in part. However, except as otherwise provided, only 85% of the initial principal amount of each May 2011 Note is convertible prior to maturity. The May 2011 Notes and warrants include a limitation on conversion or exercise, which provides that at no time will an investor be entitled to convert any portion of the May 2011 Notes or exercise any of the warrants, to the extent that after such conversion or exercise, such investor (together with its affiliates) would beneficially own more than 4.99% of the outstanding shares of our common stock as of such date.

In connection with the May 2011 offering, we entered into a Registration Rights Agreement, dated as of May 9, 2011 with the investors. Pursuant to such agreement, we agreed with the investors to provide certain rights to register under the Securities Act of 1933, as amended, the shares of our common stock issuable upon any conversion of the May 2011 Notes and the exercise of the warrants, and agreed to file a registration statement within 45 days of the closing of the May 2011 offering to register the offering of the shares of our common stock issuable upon conversion of the May 2011 Notes and the exercise of the warrants.

Rodman & Renshaw, LLC acted as the exclusive placement agent in connection with the May 2011 offering and received compensation of a cash placement fee equal to 6% of the aggregate purchase price paid by investors in the May 2011 offering and warrants to purchase 1,887,448 shares of our common stock, which warrants are exercisable at $0.15 per share and shall expire on May 12, 2014.

Reduction of Indebtedness

On May 12, 2011, in connection with the closing of the May 2011 offering, the Company received notices of conversion from holders in the aggregate amount of $907,134 (including additional interest of approximately $40,000) of our outstanding senior secured convertible promissory notes and junior unsecured convertible promissory notes pursuant to which we issued or will issue an aggregate of 6,047,561 shares of our common stock to such holders, (ii) entered into exchange agreements with certain other holders of an aggregate principal amount of $152,631 of our outstanding junior unsecured convertible promissory notes, which we refer to as the old notes, pursuant to which we issued an aggregate principal amount of $160,664 of junior unsecured convertible promissory notes, which we refer to as the new notes, in exchange for the old notes and (iii) repaid one junior unsecured convertible promissory note in the aggregate principal amount of $26,316. The new notes are substantially the same as the old notes except that the new notes have an extended maturity date of August 2, 2011.

In addition, during May 2011, the Company received notices of conversion from holders of an aggregate principal amount of $375,118 of our outstanding junior unsecured convertible promissory notes pursuant to which we issued an aggregate of 2,500,784 shares of our common stock to such holders.

The reduction of indebtedness described above reduced our aggregate principal amount of outstanding indebtedness from $2,304,984 on April 30, 2011 to $1,044,698 on June 3, 2011.

BioAdvance Note

On May 16, 2011, the Company repaid its one outstanding note to BioAdvance, dated December 17, 2003 (See Note #4). The Company repaid $40,000 in principal and $10,000 in accrued interest for a total of $50,000.

Warrants

During May 2011, investors in the Company exercised 2,333,336 warrants at a price of $0.15 per share, resulting in total proceeds to the Company of approximately $350,000. These warrants were subject to anti-dilution provisions and therefore reduced the total number of outstanding warrants, subject to anti-dilution provisions, from approximately 83.7 million warrants as of April 30, 2011 to 81.4 million warrants as of May 31, 2011.

Item 14. Indemnification of Directors and Officers.

Delaware General Corporation Law. Subsection (a) of Section 145 of the Delaware General Corporation Law, or DGCL, provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 of the DGCL further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Certificate of Incorporation and Bylaws. The registrant’s amended and restated certificate of incorporation contains provisions which provide that the registrant will indemnify the registrant’s directors and officers in each and every situation where, under Section 145 of the DGCL, as amended from time to time, the registrant is permitted or empowered to make such indemnification, and to the fullest extent permitted by law. The registrant may, in the sole discretion of its Board of Directors, indemnify any other person who may be indemnified pursuant to Section 145 of the DGCL to the extent the Board of Directors deems advisable, as permitted by Section 145 of the DGCL.

Additionally, the registrant’s amended and restated certificate of incorporation provides that no person shall be personally liable to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director; provided, however, that such foregoing provision does not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is subsequently amended to further eliminate or limit the liability of a director, then a director of the registrant, in addition to the circumstances in which a director is not personally liable as set forth in provision described in the preceding sentence, will not be liable to the fullest extent permitted by the amended DGCL.

II-1

The registrant’s bylaws contain provisions which provide, among other things, that the registrant shall indemnify any officer or director who was or is a party or is threatened to be made a party to any threatened, pending or completed (i) action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the registrant) by reason of the fact that he is or was a director, officer, employee or agent of the registrant, or is or was serving at the request of the registrant as a director, officer, employee or agent of another registrant, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the registrant, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful and (ii) action or suit by or in the right of the registrant to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the registrant, or is or was serving at the request of the registrant as a director, officer, employee or agent of another registrant, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the registrant; except that no indemnification shall be made in respect of any claim, issue or matters as to which such person shall have been adjudged to be liable to the registrant unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. Any indemnification under the provisions in the bylaws (unless ordered by a court) shall be made by the registrant only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth above. Such determination shall be made (i) by a majority vote of the directors who were not parties to such action, suit or proceeding even though less than a quorum, or (ii) if there are no such directors, or, if such directors so direct, by independent legal counsel in a written opinion, or (iii) by the stockholders. To the extent, however, that a director, officer, employee or agent of the registrant has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith, without the necessity of authorization in the specific case.

Insurance Policies. The registrant has directors and officer’s liability insurance in an amount not less than $5 million.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Commission such indemnification is against public policy as expressed in such Securities Act and is therefore unenforceable.

Item 15. Recent Sales of Unregistered Securities.

During the last three years, the registrant has issued unregistered securities to the persons, as described below. None of these transactions involved any underwriters, underwriting discounts or commissions, except as specified below, or any public offering, and the registrant believes that, except as set forth below, each transaction was exempt from the registration requirements of the Securities Act of 1933 by virtue of Section 4(2) thereof and/or Regulation D promulgated thereunder. All recipients had adequate access, though their relationships with the registrant, to information about the registrant.

On April 4, 2008, the registrant issued 153,846 shares of common stock in connection with a settlement of an agreement with its former chief executive officer and president, Roni Appel, and 750,000 shares of common stock were issued to it current chief executive officer, Thomas M.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a twenty percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment, any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) If the registrant is relying on Rule 430B:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933, shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

II-12

(ii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
