(a)      The Trustees of the University of Pennsylvania
(b)      The Reporting Person is a Pennsylvania non-profit corporation with a
         business address of c/o Center for Technology Transfer, 3160 Chestnut

         operates a private university, health care system and hospital, and
         academic research enterprise.

         convicted in a criminal proceeding (excluding traffic violations or
         similar misdemeanors).
(e)      The Reporting Person has not, during the last five years, been party to
         a civil proceeding of a judicial or administrative body of competent
         jurisdiction and as a result of such proceeding was or is subject to a
         judgment, decree or final order enjoining future violations of, or
         prohibiting or mandating activities subject to, federal or state
         securities laws or finding any violation with respect to such laws.
(f)      Pennsylvania, United States of America

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         On November 12, 2004 the Issuer closed on a Share Exchange and
Reorganization Agreement, dated as of August 25, 2004, with Advaxis, Inc., a
Delaware corporation ("Advaxis"), and the shareholders of Advaxis (the "Advaxis
Shareholders"), which set forth the terms and conditions of the exchange by the
Advaxis Shareholders of their shares of common stock and preferred stock of
Advaxis, representing all of the issued and outstanding capital stock of
Advaxis, in exchange for the issuance by the Issuer to the Advaxis Shareholders
and certain financial advisors of an aggregate of 16,350,323 shares of the
Issuer's common stock (the "Share Exchange"). Effective at the closing of the
Share Exchange, Advaxis became a wholly-owned subsidiary of the Issuer. On
November 12, 2004, the Issuer closed on a private placement of $2,925,000 to a
group of institutional and other private investors and $595,000 of bridge notes
were converted into the Issuer's equity securities on the same terms as all of
the other investors in the private placement (the "Offering").

         The Reporting Person was a shareholder of Advaxis prior to the Share
Exchange and on November 12, 2004 acquired 6,339,282 shares of the Issuer's
Common Stock (the "Securities").

ITEM 4.  PURPOSE OF TRANSACTION

         As described in Item 3 above, the Reporting Person acquired the
Securities in connection with the Share Exchange and the Offering. The Reporting
Person presently considers the Securities as an investment and intends to review
its investment on an ongoing basis. Such continuing review may result in the
Reporting Person acquiring additional Securities in the open-market or in
privately negotiated transactions, maintaining its holdings at current levels or
selling all or a portion of holdings in the open-market or in privately
negotiated transactions. Any such actions the Reporting Person may undertake
will be dependent upon, among other things: the availability of shares of Common
Stock for purchase and the price levels of such shares; general market and
economic conditions; on-going evaluation of the Issuer's business, financial
condition, operations and prospects; the relative attractiveness of alternative
business and investment opportunities; the availability of funds for the
purchase of additional shares of Common Stock; the actions of the management and
Board of Directors of the Issuer; and other future developments. Except as set
forth above, the Reporting Person has no present plans or intentions which would
result in or relate to any of the transactions described in subparagraphs (a)
through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

(a) As a result of the Share Exchange, the Reporting Person beneficially owns
6,339,282 shares of common stock of the Issuer. This constitutes 20.13% of the
31,488,161 total shares outstanding as of November 18, 2004, as set forth in the
Issuer's Current Report on Form 8-K with the Securities and Exchange Commission
(the "SEC") filed on or about November 18, 2004.

(b) The Reporting Person has sole power to vote or to direct the vote and sole
power to dispose or to direct the disposition of 6,339,282 shares of Common
Stock.

(c) Except as set forth herein, to the knowledge of the Reporting Person, no
transactions in the class of securities reported on were effected during the
last 60 days by the Reporting Person.

(d) Other than as set forth in Items 3, 4 and 5 of this Schedule 13D, to the
knowledge of the Reporting Person no other person is known to have the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of the shares of the Issuer's Common Stock which are the subject
of this Schedule 13D.

(e) Not applicable.

         TO SECURITIES OF THE ISSUER
