ACPIII, AEPIII, ACMPIII, APII, and the Managing Directors are sometimes hereinafter collectively referred to as the "Reporting Persons". By virtue of the relationships described above and their roles with APII, each of the Managing Directors may be deemed to control APII and ACMPIII, and therefore, may be deemed to possess indirect beneficial ownership of shares of Series A-2 Stock held by ACPIII and AEPIII. However, none of the Managing Directors, acting alone, has voting or investment power with respect to the shares of the Series A-2 Stock directly beneficially held by ACPIII and AEPIII and, as a result, the Managing Directors disclaim beneficial ownership of the shares of Series A-2 Stock directly beneficially owned by ACPIII and AEPIII, except to the extent of their pecuniary interest therein. AEPIII is a side company that makes all investments pro rata to the capital of ACPIII with all allocations made to its members based on paid-in capital. The Managing Directors, by virtue of being managing directors of ACPIII and the managers of AEPIII, are affiliates of APII. (b) The principal executive offices of ACPIII, AEPIII, ACMPIII, APII, and the business address of each Managing Director, are located at One Embarcadero Center, Suite 4050, San Francisco, California 94111. (c) APII provides investment advisory services to several venture capital firms, including ACPIII and AEPIII. ACPIII and AEPIII's principal business is acting as venture capital investment vehicles. ACMPIII's principal business is acting as managing director of ACPIII. Each of the Managing Directors' principal business is acting as a managing director of ACMPIII and as an officer or employee of APII. (d) During the past five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). Page 9 of 14 Pages (e) During the past five years, none of the Reporting Persons was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person 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 of finding any violation with respect to such laws. (f) APII is a California corporation. ACPIII is a Delaware limited partnership. AEPIII is a California limited liability company. ACMPIII is a Delaware limited liability company. Each of the Managing Directors is a citizen of the United States. Item 3. Source and Amount of Funds or Other Consideration. On January 7, 2005 (the "Closing Date"), ACPIII and AEPIII entered into a Stock Purchase Agreement (the "Stock Purchase Agreement") with the Issuer pursuant to which ACPIII and AEPIII acquired, for an aggregate purchase price of $1,250,000.00, a total of 125,000 shares of Series A-2 Stock, (convertible into 11,363,636 shares of Common Stock). The total amount of funds required by ACPIII to acquire the 120,917 shares of Series A-2 Stock (convertible into 10,992,454 shares of Common Stock) reported in Item 5(a) hereof was $1,209,170.00 and the total amount of funds required by Embarcadero LLC to acquire the 4,083 shares of Series A-2 Stock (convertible into 371,182 shares of Common Stock) reported in Item 5(a) hereof was $40,830.00. Such funds were provided by each entity's capital available for investment. No part of the purchase was or will be represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting such securities. By virtue of the relationships described in Item 2: each of the Managing Directors of APII may be deemed to control APII and ACMPIII, and therefore, may be deemed to possess indirect beneficial ownership of shares of Series A-2 Stock held by ACPIII and AEPIII. Item 4. Purpose of Transaction. ACPIII and AEPIII acquired the Series A-2 Stock reported in Item 5(a) for investment purposes only. Depending upon their evaluation of the Issuer's investments and prospects, and upon future developments (including, but not limited to, the market for the Issuer's securities, the effective yield, availability of funds, alternative uses of funds, and money, stock market and general economic conditions), each of the Reporting Persons may from time to time purchase additional Issuer securities, dispose of all or a portion of the Issuer's securities that it holds, or cease buying or selling Issuer's securities. Any such additional purchases or sales of the Issuer's securities may be in open market or privately negotiated transactions or otherwise. Except as otherwise described herein or as expressly stated below, none of the Reporting Persons has any present plans, which relate to or would result in: Page 10 of 14 Pages (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 of any of its subsidiaries; (d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or 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, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuers 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 Securities Exchange Act of 1934; or (j) Any action similar to any of those enumerated above.

The foregoing percentages are calculated based upon 268,569,669 shares of the Issuer's Common Stock reported to be outstanding as of January 7, 2005 in a Current Report on Form 8-K, filed by the Issuer with the Securities and Exchange Commission on January 13, 2005.
