Item 4. Purpose of the Transaction

      The Reporting Person holds the Shares as reported herein for the purpose
of investment. Except as described herein, the Reporting Person has not
formulated any plans or proposals which relate to or would result in:

      (a) the acquisition by any person of additional securities of the Issuer,
or the disposition of securities of the Issuer;

      (b) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Issuer or any of its subsidiaries;

      (c) a sale or transfer of a material amount of assets of the Issuer or any
of its subsidiaries;

      (d) any change in the present board of directors of the Issuer, including
any plans or proposals to change the number of term of directors or to fill any
existing vacancies on the board;

      (e) any material change in the present capitalization or dividend policy
of the Issuer;

      (f) any other material change in the Issuer's business or corporate
structure;

      (g) changes in the Issuer's charter or bylaws or other actions which may
impede the acquisition of control of the Issuer by any person;

      (h) causing a class of securities of the Issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;

      (i) a class of equity securities of the Issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or

      (j) any action similar to any of those enumerated above.

      In connection with the Financing, the Issuer issued 2,575,000 shares of
its Series A Stock for $1.00 per share. Each share of Series A Stock is
initially convertible into 33.334 shares of common stock. The holders of the
Series A Stock will be entitled to a cumulative annual dividend of 15%, which,
at the option of the lead investor, New Century Equity Holdings Corp., a
Delaware corporation, ("New Century"), may be paid in cash or in additional
shares of Series A Stock. The holders of the Series A Stock will have a
liquidation preference in the event of any liquidation, sale, merger or similar
event, and have registration rights and other customary rights. The Issuer has
also agreed to make payments to the holders of the Series A stock, to the extent
its cash flow meets certain levels, until the holders have received the amount
of their investment in the Series A Stock; has granted a security interest in
all of its assets to secure its obligation to make these payments; and has
agreed to issue additional shares of Series A Stock equal to 50% of the then
fully diluted common stock to the holders if the Issuer fails to return the
amount of their investment, plus the mandatory dividends, by July 15, 2003. The
Issuer has also agreed to issue, at up to six different times, additional shares
of Series A Stock to the investors equal to 25% of the then fully diluted common
stock if the Issuer fails to meet any of certain financial targets, beginning
with the quarter ending Sept. 30, 2001. If the slowdown in the worldwide
semiconductor industry continues for an extended period of time, the Issuer may
not meet one or more of the specified financial


                                       4


targets, thus triggering the issuance of additional shares of Series A Stock. At
the Issuer's Annual Meeting of Stockholders, the shareholders voted on and
approved a proposal to authorize additional common stock necessary to facilitate
the conversion of the Series A Stock. In connection with the transaction
described above, two members of the Board of Directors of the Issuer resigned,
and New Century appointed two directors to the Board. Subject to certain
requirements, New Century will have the right to appoint a third member to
Issuer's five-member Board of Directors.

      The Reporting Person reserves the right to (i) modify his present
intentions and formulate plans or proposals to take any one or more of the
actions referred to in paragraph (a) through (j) above and (ii) to increase or
decrease his respective holdings of Common Stock through open market purchases,
privately negotiated transactions or otherwise.

Item 5. Interest in Securities of the Issuer

      (a) As set forth herein, the Reporting Person beneficially owns 73,912,210
Shares, which represent 75.37% of the outstanding Shares, based upon the number
of Shares outstanding as of the most recent practicable date.

      (b) As set forth herein, the Reporting Person has sole voting and
dispositive power over the 73,912,210 Shares that he beneficially owns. The
Reporting Person does not share voting or dispositive power over any Shares.

      (c) The Reporting Person acquired beneficial ownership of 14,071,614 of
the Shares described herein on October 30, 2001 as described herein.

the Shares described herein on January 30, 2002 as described herein.

        Securities of the Issuer

      The information set forth, or incorporated by reference, in Items 1
through 5 is hereby incorporated herein by reference. Except as described in
