7. REGISTRATION RIGHTS

7.1 Piggyback Registration.

(a) If the Corporation shall determine to register any of its securities under the 1933 Act for its own account, other than a registration relating solely to employee benefit plans, or a registration relating to a corporate reorganization or other transaction on Form S-4 or any successor form, or any registration on any registration form that does not permit secondary sales, the Corporation will:

(i) promptly give to the Subscriber written notice thereof;

(ii) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 7.1(b) below, and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made by the Subscriber and received by the Corporation within ten (10) days after the written notice from the Corporation described in clause (i) above (such written request may specify all or a part of the Subscriber’s Registrable Securities); and

(iii) the Corporation shall have the right to terminate or withdraw any registration initiated by it under this Section 7.1(a) prior to the effectiveness of such registration whether or not the Subscriber has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Corporation.

(b) If the registration of which the Corporation gives notice is for a registered public offering involving an underwriting, the Corporation shall so advise the Subscriber as a part of the written notice given pursuant to Section 7.1(a)(i). In such event, the right of the Subscriber to registration pursuant to this Section 7.1(b) shall be conditioned upon the Subscriber’s participation in such underwriting and the inclusion of the Subscriber’s Registrable Securities in the underwriting to the extent provided herein. The Subscriber shall (together with the Corporation and the other holders of securities of the Corporation with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Corporation.

Notwithstanding any other provision of this Section 7.1, if the representative of the underwriters advises the Corporation in writing that marketing factors require a limitation on the number of shares to be underwritten, the representative may (subject to the limitations set forth below) exclude all Registrable Securities from, or limit the number of Registrable Securities to be included in, the registration and underwriting. The Corporation shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated first to the Corporation for securities being sold for its own account and thereafter pro rata in accordance with the number of Common Shares requested to be included in such registration. If any person does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Corporation or the underwriter. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

If shares are so withdrawn from the registration and if the number of shares of Registrable Securities to be included in such registration was previously reduced as a result of marketing factors, the Corporation shall then offer to all persons who have retained the right to include securities in the registration the right to include additional securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated pro rata among the persons requesting additional inclusion.

7.2 Cooperation and Indemnification. The Corporation agrees to indemnify and hold harmless the Subscriber against any losses, damages or liabilities to which the Subscriber may become subject under the 1933 Act or otherwise insofar as said losses damages or liabilities (or actions in respect thereof) relate to the sale of stock by them in connection with such registration statement, arising from any untrue statement or alleged untrue statement of material fact or from the omission or the alleged omission therein of a material fact required to be stated therein or necessary to make the statements therein not misleading; but such indemnity shall apply only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was not made in reliance upon and in conformity with information furnished by the Subscriber for use in the preparation thereof. The Corporation agrees to reimburse the Subscriber for any legal or other expenses reasonably incurred in connection with any such loss, damage or liability. The Subscriber agrees to cooperate fully with the Corporation in the preparation and filing of any registration statement which includes any Registrable Securities owned by the Subscriber. The

Subscriber will provide at its own expense and in writing to the Corporation all information and data with respect to itself and to its plan of distribution as shall be required by the rules and regulations of the SEC to be included in any such registration statement. The Subscriber further agrees to indemnify and hold harmless the Corporation, each of its directors, and each of its officers who has signed such registration statement (or any amendments thereof) and each person, if any, who controls the Corporation, within the meaning of the 1933 Act, against any losses, damages or liabilities to which the Corporation, or any such director, officer or controlling person of the Corporation may become subject under the 1933 Act or otherwise, insofar as said losses, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement (or any amendment thereof) or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; such indemnity shall apply only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information furnished by the Subscriber for use in the preparation thereof. The Subscriber agrees to reimburse the Corporation and any such director, officer or controlling person for any legal or other expenses reasonably incurred in connection with any such loss, damage or liability.

7.3 Lock-Up. The Subscriber agrees that if so requested by an underwriter in connection with any public offering of securities by the Corporation, the Subscriber shall not sell, or make any short sale of, the Corporation’s securities without the prior written consent of the underwriter for a period of 180 days following the effective date of such registration statement.

7.4 Termination of Registration Rights. The right of the Subscriber to request inclusion in any registration pursuant to Section 7.1 shall terminate, as to any specific Registrable Security, on the earlier of (i) such date as the Registrable Security may immediately be sold under Rule 144, and (ii) two years after the Closing Date.

8. MISCELLANEOUS.

8.1 The Subscriber hereby authorizes the Corporation to correct any minor errors in, or complete any minor information missing from any of the Exhibits returned herewith.

8.2 The Corporation shall be entitled to rely on delivery by facsimile machine of an executed copy of this subscription, and acceptance by the Corporation of such facsimile copy shall be equally effective to create a valid and binding agreement between the Subscriber and the Corporation in accordance with the terms hereof.

8.3 This Agreement is not assignable or transferable by the parties hereto without the express written consent of the other party hereto, which such other party may withhold in its sole and absolute discretion.

8.4 Time is of the essence of this Agreement.

8.5 Except as expressly provided in this Agreement and in the agreements, instruments and other documents contemplated or provided for herein, this Agreement contains

the entire agreement between the parties with respect to the Units and there are no other terms, conditions, representations or warranties whether expressed, implied, oral or written, by statute, by common law, by the Corporation or by anyone else.

Any controversy or claim arising out of or relating to this Agreement, or breach thereof, including without limitation claims against either party, its affiliates, employees, professionals, officers or directors, shall be settled by binding arbitration in San Francisco, California, in accordance with the Commercial Rules of the American Arbitration Association. The arbitrator shall be an active member of the California Bar. In the proceeding, the arbitrator shall apply California substantive law and the California Evidence Code, and the arbitrator’s authority in awarding damages shall be interpreted under California law. The undersigned agrees that the arbitrator shall have no authority to award punitive damages, and the undersigned has been advised to seek counsel concerning the possible waiver by the undersigned of certain rights otherwise available to the undersigned as a consequence of such agreement. The arbitrator shall prepare an award in writing, which shall include factual findings and any legal conclusions on which the decision is based. Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction thereof. In any such proceeding, the prevailing party shall be entitled, in addition to any other relief awarded or adjudged, such sum as the arbitrator may fix as and for reasonable attorneys’ fees and costs, and the same shall be included in the award and any judgment.

8.10 This Agreement, including without limitation the representations, warranties and covenants contained herein and in each Accredited Investor Certificate, shall survive and continue in full force and effect and be binding upon the Corporation and the Subscriber, notwithstanding the completion of the purchase of the Units by the Subscriber pursuant hereto, the completion of the Offering and any subsequent disposition by the Subscriber of the Common Shares, Warrants or Warrant Shares.
