ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     On February 23, 2004, the Company entered into an Amended and Restated
Investment Agreement (the "Amended Investment Agreement") with Needham & Co.,
NCPII, NCPIIB, NCPIII, NCPIIIA, NCPIIIB and Dolphin Direct Equity Partners, LP
("Dolphin"). The Amended Investment Agreement amended and restated an Investment
Agreement, dated as of December 18, 2003 (the "Prior Investment Agreement"), for
a new bank loan guarantee and equity financing package of up to $7,500,000 from
Needham & Co., certain of its affiliates and Dolphin. As more fully described
below, on February 23, 2004, NCPII, NCPIIB, NCPIII, NCPIIIA and NCPIIIB (the
"Note Purchasers") collectively purchased $3,000,000 of Secured Convertible
Promissory Notes (the "Notes") from the Company for an aggregate purchase price
of $3,000,000, and, in connection with the issuance of the Notes and certain
anti-dilution protections, the Company issued warrants to the Note Purchasers
(the "Warrants") for an aggregate of 8,330,171 shares of Common Stock. The
source of funds used to purchase the Notes by each Note Purchaser was the
working capital of such Note Purchaser.

     On December 29, 2003, Needham & Co. filed a Schedule 13D with the
Securities and Exchange Commission (the "Commission") reporting the ownership by
the Reporting Persons of the shares of Common Stock reported herein, subject to
the disclaimers therein and herein, and a warrant issued by the Company to
Needham & Co. and the shares of Common Stock issuable upon exercise of that
warrant. The source of funds used to purchase the shares of Common Stock owned
by each of Needham & Co., NEGP, NCF, and NEGPC was the working capital of such
Reporting Person. The source of funds used to purchase the shares of Common
Stock owned by George A. Needham and members of his family held in custodial
accounts for which Mr. Needham is the custodian was the personal funds of Mr.
Needham. The warrant was issued to Needham & Co. pursuant to the terms of the
Prior Investment Agreement in consideration for providing loan guaranties
described in the Schedule 13D filed by Needham & Co. on December 29, 2003.

ITEM 4.  PURPOSE OF TRANSACTION.

     On February 23, 2004, the Company entered into the Amended Investment
Agreement, which amended the Prior Investment Agreement to provide, among other
things, for the purchase by the Note Purchasers and Dolphin of the Notes in one
traunche rather than shares of Series A 10% Cumulative Preferred Stock, par
value $0.001 per share (the "Series A Preferred Stock"), of the Company in two
traunches. Pursuant to the Amended Investment Agreement, on February 23, 2004,
the Note Purchasers purchased from the Company an aggregate principal amount of
$3,000,000 of Notes for an aggregate purchase price of $3,000,000. The Notes pay
interest at an annual interest rate equal to the lower of 10% or the highest
rate permitted by applicable law, compounded daily.


                                       2




     The Notes are convertible, in whole or in part, at the option of the holder
into shares of Preferred Stock at a rate of one share of Series A Preferred
Stock for each $1.00 of debt converted, subject to specified adjustments. The
Notes are secured by a pledge of a portion of the stock of the Company's
subsidiary, Southwall Europe GmBH, pursuant to a Pledge Agreement between the
Company and the Note Purchasers. Upon conversion of a majority of the aggregate
principal outstanding under the Notes, the remaining Notes will automatically
convert. The Notes are due and payable February 20, 2009, or earlier upon the
occurrence of an event of default under the Notes, as specified in the Amended
Investment Agreement. The approval of the holders of the Notes will be required
for the Company to take certain actions, including the consummation of any
merger or sale of the Company or all or substantially all of its assets. The
Series A Preferred Stock into which the Notes are convertible are in turn
convertible on a one-for-one basis into Common Stock, have a preference over the
Common Stock in the event of a liquidation or winding up of the Company, and
carry a cumulative dividend of 10% per annum along with other protective and
anti-dilution provisions. The approval of a majority of the holders of the
outstanding shares of Series A Preferred Stock will be required for the Company
to take certain actions, including the consummation of any merger or sale of the
Company or all or substantially all of its assets.

     In connection with the purchase of the Notes and in satisfaction of the
anti-dilution rights of the Note Purchasers relating to the issuance by the
Company of debt and equity to certain creditors, the Company issued the Warrants
to the Note Purchasers for an aggregate of 8,330,171 shares of Common Stock with
an exercise price of $0.01 per share. The Warrants are immediately exercisable
and expire on February 20, 2009.

     Pursuant to the Amended Investment Agreement, the Company has granted
Needham & Co. board observer rights. The Company also granted certain
registration rights to the Note Purchasers with respect to the shares of Common
Stock underlying the Notes and the Warrants.

     Other than as specified in this Item 4, the Reporting Persons have no plans
or proposals which relate to or which would result in or relate to any of the
actions specified in paragraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

     (a) (1) Needham & Co. owns of record and beneficially 737,067 shares of
Common Stock and a warrant, which is immediately exercisable for 941,115 shares
of Common Stock. Assuming the full exercise of the warrant, Needham & Co. would
own of record 1,678,182 of Common Stock, which would constitute 13.38% of the
issued and outstanding Common Stock.

     (2) NEGP owns of record and beneficially 300,000 shares of Common Stock,
which constitutes 2.39% of the issued and outstanding Common Stock.

     (3) NCF owns of record and beneficially 300,000 shares of Common Stock,
which constitutes 2.39% of the issued and outstanding Common Stock.


                                       3




     (4) NEGPC owns of record and beneficially 100,000 shares of Common Stock,
which constitutes 0.80% of the issued and outstanding Common Stock.

     (5) NMP may be deemed to own beneficially the aggregate amount of 700,000
shares of Common Stock owned by NEGP, NCF and NEGPC by virtue of its position as
general partner of those Reporting Persons, which amount constitutes 5.58% of
the issued and outstanding Common Stock. NMP disclaims beneficial ownership of
all of the reported shares of Common Stock owned by NEGP, NCF and NEGPC, and the
