Footnotes to Item 5:

(1) All such shares are directly held and directly beneficially owned by VPVP IV Q. VantagePoint Venture Associates IV, L.L.C., as the general partner of VPVP IV Q, and Messrs. Marver and Salzman, as the managing members of VantagePoint Venture Associates IV, L.L.C., may be deemed to share voting and investment power with VPVP IV Q with respect to such shares. With respect to Messrs. Marver and Salzman, this Statement relates only to their indirect beneficial ownership of such shares.

(2) All such shares are directly held and directly beneficially owned by VPVP IV. VantagePoint Venture Associates IV, L.L.C., as the general partner of VPVP IV, and Messrs. Marver and Salzman, as the managing members of VantagePoint Venture Associates IV, L.L.C., may be deemed to share voting and investment power with VPVP IV with respect to such shares. With respect to Messrs. Marver and Salzman, this Statement relates only to their indirect beneficial ownership of such shares.

(3) All such shares are directly held and directly beneficially owned by VPVP Principals IV. VantagePoint Venture Associates IV, L.L.C., as the general partner of VPVP Principals IV, and Messrs. Marver and Salzman, as the managing

Page 9 of 12

members of VantagePoint Venture Associates IV, L.L.C., may be deemed to share voting and investment power with VPVP Principals IV with respect to such shares. With respect to Messrs. Marver and Salzman, this Statement relates only to their indirect beneficial ownership of such shares.

(c) None of the Reporting Persons has effected any transactions in the class of securities reported on this Schedule 13D during the past sixty (60) days. In November 2003, VPVP IV Q and VPVP IV collectively converted 4,000,000 shares of Series A Preferred Stock on a one-to-one basis into shares of Common Stock and distributed 3,999,921 of these shares to the limited partners of those two funds.

(d) VantagePoint Venture Associates IV, L.L.C. is the general partner of each of the VantagePoint Funds. Messrs. Marver and Salzman are the managing members of VantagePoint Venture Associates IV, L.L.C. and therefore have the power to vote and dispose of shares of the Issuer's Common Stock held by the VantagePoint Funds. Under certain circumstances set forth in the operating agreement of VantagePoint Venture Associates IV, L.L.C., the members of such limited liability company have the right to receive distributions, either cash or in-kind, with respect to the shares of the Issuer's Common Stock held by the VantagePoint Funds. In addition, under certain circumstances set forth in the limited partnership agreement of the VantagePoint Funds, the partners of such partnerships have the right to receive distributions, either cash or in-kind, with respect to the shares of the Issuer's Common Stock that the VantagePoint Funds hold. To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of distributions with respect to the securities of the Issuer.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Except as described in this Statement, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons and any other person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finders fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

Pursuant to the Series A Preferred Share Purchase Agreement, the VantagePoint Funds purchased 22,000,000 shares of Series A Convertible Preferred Stock at a purchase price of CDN $1.00 (U.S. $0.71) per share. The Series A Convertible Preferred Stock is convertible at any time, at the option of the shareholder, and in certain circumstances at the option of the Issuer, into one share of the Issuer's Common Stock. As a condition to the obligations of the parties under the Series A Preferred Share Purchase Agreement, among other things, the Issuer and the investors entered into an Investors' Rights Agreement (as defined and described below) and an indemnification agreement for the benefit of the director representatives of the investors. Also pursuant to the Series A Preferred Stock Purchase Agreement, the Company agreed to take all reasonable steps to ensure that two individuals would be elected to the Board as the initial representatives of the holders of the Series A Preferred Stock (which individuals previously, but no longer, serve as members of the Board). The Issuer also agreed to indemnify and hold harmless each of the investors and each permitted transferee of the Series A Preferred Stock from and against any and all claims as a result of misrepresentations or breach of any representation or warranty, breaches of covenants, the execution and performance of the agreement, or the Issuer infringing the intellectual property rights of any third party in any material manner.

In connection with the execution of the Series A Preferred Share Purchase Agreement, the Issuer and the VantagePoint Funds entered into an Investors' Rights Agreement, dated as of June 18, 2003 (the "Investors' Rights Agreement"). Subject to certain qualifications enumerated therein, the Investors' Rights Agreement provides, among other things, that the holders of a majority of the shares of Common Stock issuable or issued upon conversion of the Series A Preferred Stock may demand that the Issuer file a registration statement under the Securities Act of 1933 (the "Securities Act") with respect to such securities. The holders of the Series A Preferred Stock initiating the registration request may request to distribute their securities by means of an underwriting, with the underwriters to be selected by the initiating holders, which underwriter shall be reasonably acceptable to the Issuer. The Issuer has the right to defer the filing of any such registration statement for up to 90 days following receipt of the request from holders of the Series A Preferred Stock if it shall determine in its good faith judgment that to do so would be seriously detrimental to the Issuer and its shareholders, provided that such right may not be exercised more than once in any twelve-month period. The Investors' Rights Agreement also gives to the holders of the Series A Preferred Stock "piggyback" registration rights in the event the Issuer proposes to register any of its stock under the Securities Act in connection with the U.S. public offering of such securities. In addition, the holders of at least 35% of the Series A Preferred Stock may, under certain conditions, demand that the Issuer file a registration statement on Form S-3 to permit or facilitate the sale and distribution of such holder's securities. In addition, pursuant to the Investors' Rights Agreement, subject to certain exceptions, the Issuer granted the VantagePoint Funds, and their respective partners, general partner, managing members or affiliates or any affiliated fund a "right of first offer" with respect to future sales by the Issuer of its shares or securities convertible into or exercisable for any shares of its capital stock, up to the proportion that the amount of shares of Common Stock held by such investor, or issuable upon conversion of such issuer's convertible securities, bears to the total number of shares of Common Stock outstanding plus any shares issuable pursuant to an employee stock plan. The Investors' Rights Agreement also stipulates that in connection with the closing of the transactions contemplated under the Series A Preferred Share Purchase Agreement, the Issuer shall use its best efforts to nominate, recommend and support for the election to the Board of Directors of the Issuer two representatives designated by a majority-in-interest of the investors.

In November 2003, VPVP IV Q and VPVP IV converted 4,000,000 shares of Series A Preferred Stock on a one-to-one basis into shares of Common Stock. In connection with this conversion, the Issuer and the VantagePoint Funds entered into a Letter Agreement dated as of November 18, 2003 (the "Lock-up Agreement") by which the VantagePoint Funds would refrain from selling or distributing the remaining 18,000,000 shares of Series A Preferred Stock for a specified period of time. The Lock-up Agreement stipulated that the Series A Preferred Stock was to be released from the Lock-up Agreement in three equal installments in February, May and August of 2004. As of the date hereof, all 18,000,000 outstanding shares of Series A Preferred Stock subject to the Lock-up Agreement have been released, but have not yet been converted into shares of Common Stock. Also under the Lock-up Agreement, each party agrees to indemnify and save the other party from and loss or liability suffered as a result of any breach of any representations, warranties or covenant in the agreement.

The descriptions of the Series A Preferred Share Purchase Agreement, the Investors' Rights Agreement and the Lock-up Agreement contained elsewhere in this Statement are incorporated herein by reference, and are qualified in their entirety by the full text of the Series A Preferred Share Purchase Agreement, the Investors' Rights Agreement and the Lock-up Agreement which are included as Exhibits 99.2, 99.3, and 99.4, respectively, to this Statement.
