(d) and (e) During the past five years, none of the Reporting Persons or, to the best knowledge of the Reporting Persons, any of the persons listed on Schedule I, (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) has been a 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. Item 3. Source and Amount of Funds or Other Consideration. The Schedule 13D filed by the Reporting Person on March 8, 2004 reported the issuance by the Company to the Reporting Persons of warrants to purchase shares of Common Stock and Secured Convertible Promissory Notes ("Notes") pursuant to an Investment Agreement by and among the Company, certain of the Reporting Persons and Dolphin Direct Equity Partners, L.P., (collectively, the "Investor Parties") which agreement was subsequently amended and restated, as more fully described in the Schedule 13D (the "Investment Agreement"). Pursuant to Section 4.14 of the Investment Agreement, if, as part of its restructuring efforts, the Company issues any equity or warrants, options, rights or other instruments exercisable or convertible into equity, to any creditor, landlord, employee, director, agent or consultant, then the Company is required to issue additional warrants to any Investor Parties who at the time of such issuance had pursuant to the Investment Agreement provided loan guaranties to the Company or purchased Secured Convertible Promissory Notes from the Company in such amounts as would allow the Investor Parties to maintain their aggregate ownership percentage (on a fully-diluted basis) as if such issuance had not occurred. Section 4.14 of the Investment Agreement also provides that if, as part of the Company's restructuring efforts, the Company issues notes or other debt instruments to any of its creditors, then it is required to issue additional warrants to such Investor Parties representing the right to purchase that number of shares of Common Stock equal to the product of (x) 1.25 and (y) the original principal amount of such note or debt instrument. The Reporting Persons inadvertently omitted to report the transactions described below in the Schedule 13D relating to warrants issued to Needham & Co. pursuant to the Investment Agreement. On December 18, 2003, Needham & Co. entered into an agreement (the "Needham/Dolphin Agreement") with Dolphin Direct Equity Partners, L.P. ("Dolphin") pursuant to which Dolphin agreed to provide funds in connection with the loan guaranty provided by Needham & Co. to the Company and Needham & Co. agreed to transfer to Dolphin one-third of the warrants issued to Needham & Co. by the Company in connection with such loan guaranty, including warrants issued pursuant to the anti-dilution rights set forth in Section 4.14 of the Investment Agreement. Pursuant to the Needham/Dolphin Agreement, Needham & Co. transferred to Dolphin, at Needham's cost, warrants exercisable for 313,705 shares of Common Stock at an exercise price of $0.01 per share issued to Needham on December 18, 2003, which warrants constituted a portion of the warrant for 941,155 shares of Common Stock issued to Needham & Co. pursuant to the Investment Agreement on December 18, 2003 (which warrant is described in a Schedule 13D filed by Needham & Co. on December 29, 2003), as well as the warrants described below issued by the Company to Needham & Co. pursuant to Section 4.14 of the Investment Agreement. On December 18, 2003, the Company and Pacific Business Funding, a division Greater Bay Bank, N.A. ("PBF"), entered into a Forbearance Agreement in which PBF agreed to forbear until May 5, 2004 from pursuing its remedies pursuant to certain defaults by the Company under a factoring line of credit previously entered into between the parties. In connection with the execution of the Forbearance Agreement, the Company issued PBF a warrant to purchase a total of 250,000 shares of Common Stock at an exercise price of $0.01 per share. Additionally, on December 18, 2003, the Company's directors were issued options exercisable for 56,461 shares of Common Stock in lieu of cash fees for attendance at Board meetings. As a result of these issuances, pursuant to Section 4.14 of the Investment Agreement, the Company issued to Needham & Co. warrants to purchase a total of 26,551 shares of common stock at an exercise price of $0.01 per share. Pursuant to the Needham/Dolphin Agreement, Needham & Co. then transferred warrants exercisable for 5,772 shares of Common Stock to Dolphin at Needham's cost. On January 15, 2004, the Company issued to Needham & Co. a warrant to purchase 941,115 shares of Common Stock at an exercise price of $0.01 per share (the "January 2004 Warrant"). The January 2004 Warrant was issued to Needham & Co. pursuant to the terms of the Investment Agreement in consideration for providing a loan guaranty. Pursuant to the Needham/Dolphin Agreement, Needham & Co. then transferred warrants exercisable for 313,705 shares of Common Stock to Dolphin at Needham's cost. On January 19, 2004, PBF consented to a guarantee by Southwall Europe GmbH of the obligation owed by the Company to Teijin Limited pursuant to a Guaranteed Loan Agreement. In connection with the consent, the Company issued PBF a warrant to purchase a total of 75,000 shares of common stock at an exercise price of $0.01 per share. As a result of this issuance, pursuant to Section 4.14 of the Investment Agreement, the Company issued to Needham & Co. warrants to purchase a total of 10,082 shares of common stock at an exercise price of $0.01 per share. Pursuant to the Needham/Dolphin Agreement, Needham & Co. then transferred warrants exercisable for 2,649 shares of Common Stock to Dolphin at Needham's cost. On January 30, 2004 PBF agreed to amend the Forbearance Agreement to allow for changes to the Investment Agreement. In connection with the amendment, the Company issued to PBF a warrant to purchase a total of 35,000 shares of Common Stock at an exercise price of $0.01 per share. As a result of this issuance, pursuant to Section 4.14 of the Investment Agreement, the Company issued to Needham & Co. warrants to purchase a total of 4,702 shares of Common Stock at an exercise price of $0.01 per share. Pursuant to the Needham/Dolphin Agreement, Needham & Co. then transferred warrants exercisable for 1,235 shares of Common Stock to Dolphin at Needham's cost. Item 4. Purpose of Transaction.
