The principal business office and mailing address of the Reporting Persons is c/o Needham & Company, Inc., 445 Park Avenue, New York, New York 10022.

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 inclusion of these shares of Common Stock in this report shall not be deemed an admission by it of beneficial ownership of such shares for any purpose. (6) George A. Needham owns of record and beneficially 30,000 shares of Common Stock. He also may be deemed to beneficially own (i) the shares of Common Stock and the warrant owned by Needham & Co. by virtue of his position in and share ownership of Needham & Co., (ii) the shares of Common Stock owned by NEGP, NCF and NEGPC by virtue of his position as general partner of NMP, the general partner of NEGP, NCF and NEGPC, (iii) the Notes and Warrants owned by NCPII, NCPIII and NCPIIIA by virtue of his position as a manager of NCM, the general partner of NCPII, NCPIII and NCPIIIA, (iv) the Notes and Warrants owned by NCPIIB and NCPIIIB by virtue of his position as a manager of NCMB, and (v) 5,000 shares of Common Stock owned by family members of Mr. Needham. The aggregate amount of shares of Common Stock owned by Mr. Needham and his family members is 35,000, which constitutes 0.28% of the issued and outstanding shares of Common Stock. Mr. Needham disclaims beneficial ownership of all of the reported shares of Common Stock and the Warrants, except the shares of Common Stock he owns of record, and the inclusion of these shares in this report shall not be deemed an admission by him of beneficial ownership for any purpose. (7) NCPII owns of record and beneficially (i) a Note in the principal amount of $877,058, which is convertible to 877,058 shares of Preferred Stock, which in turn is convertible to 877,058 shares of Common Stock, subject to adjustments applicable to the Note and Preferred Stock, and (ii) a Warrant which is exercisable for 2,435,348 shares of Common Stock.
