Registration. (a) If at any time or from time to time following the date hereof, the Company shall determine to register any distribution of its securities with the SEC, either for its own account or the account of a security holder or holders, in a registration statement covering the sale of shares of Common Stock to the general public pursuant to a public offering in compliance with the Act (except with respect to any registration filed on Form S-4 or such other form which does not include substantially the same information as would be included in a registration statement covering the sale of shares of Common Stock to the general public), the Company will: (i) give to Stockholder written notice thereof at least 30 days before the initial filing of such registration statement; and (ii) include in such registration (and any related qualification under blue sky laws) and in any underwriting involved therein, all the Shares, specified in a written request, made within 30 days after receipt of such written notice from the Company, by the Stockholder, except as set forth in subparagraphs (b) or below.

(b) If the distribution is to be underwritten, the right of the Stockholder to registration pursuant to this Section shall be conditioned upon Stockholder's participation in the underwriting and the inclusion of the Shares and securities underlying the Shares, as the case may be, in the underwriting to the extent provided herein. Notwithstanding any other provision of this Section, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, and such determination is made by such underwriter in writing, then the underwriter may limit the number of the Stockholder's Shares to be included in the registration and underwriting, or may exclude the Shares from such underwriting. 4. Obligations of the Company. In connection with a registration of the Registrable Securities under Section 3 hereof, the Company shall do each of the following: (a) Prepare and file with the SEC, a Registration Statement with respect to the Registrable Securities, and thereafter use its best efforts to cause each Registration Statement relating to the Registrable Securities to become effective on or before 120 days from the filing of such Registration Statement with the SEC, and keep the Registration Statement effective at all times until the earliest (the "Registration Period") of (i) the date that is three years after the Closing Date; (ii) the date when the Stockholder may sell all Registrable Securities under Rule 144 or (iii) the date the Stockholder no longer owns any of the Registrable Securities, which Registration Statement shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; -3- (b) Prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to keep the Registration Statement effective at all times during the Registration Period, and, during the Registration Period, comply with the provisions of the Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statement; (c) The Company shall permit a single firm of counsel designated by the Stockholder to review the Registration Statement a reasonable period of time prior to the Company's filing of the Registration Statement with the SEC; (d) Furnish to the Stockholder (i) promptly after the Registration Statement is prepared and publicly distributed, filed with the SEC, or received by the Company, one copy of the Registration Statement, each prospectus, and each amendment or supplement thereto, and (ii) such number of copies of a prospectus, and all amendments and supplements thereto and such other documents, as the Stockholder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by the Stockholder; (e) As promptly as practicable after becoming aware of such event, the Company shall notify the Stockholder of (i) the issuance by the SEC of a stop order suspending the effectiveness of the Registration Statement, (ii) the happening of any event of which the Company has knowledge as a result of which the prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) the occurrence or existence of any pending corporate development that, in the reasonable discretion of the Company, makes it appropriate to suspend the availability of the Registration Statement, and use its best efforts promptly to prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to the Stockholder as he may reasonably request; provided that, for not more than twenty days (or a total of not more than forty days in any twelve month period, the Company may delay the disclosure of material non-public information concerning the Company (as well as prospectus or Registration Statement updating) the disclosure of which at the time is not, in the good faith opinion of the Company, the best interests of the Company and in the opinion of counsel to the Company (an "Allowed Delay"); provided, further, that the Company shall promptly (i) notify the Stockholder in writing of the existence of material non-public information giving rise to an Allowed Delay and (ii) advise the Stockholder in writing to cease all sales under the Registration Statement until the end of the Allowed Delay.

At least five days prior to the first anticipated filing date of the Registration Statement, the Company shall notify the Stockholder of the information the Company requires from the Stockholder (the "Requested Information") if the Stockholder elects to have any of the Stockholder's Registrable Securities included in the Registration Statement.

(b) All underwriting discounts and commissions incurred in connection with registrations shall be paid by the Stockholder. 7. Indemnification. Hsu shall indemnify and hold harmless the Company and each officer, director or control person of any such entity, who is or may be a party or is or may be threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of or arising from (i) any actual or alleged misrepresentation or misstatement of facts or omission to represent or state facts made or alleged to have been made by Hsu to the Company, (or its officers, directors, employees, agents or representatives), or omitted or alleged to have been omitted by Hsu, concerning Hsu, or Hsu's authority to invest or financial position in connection with the offering or sale of the Shares, or (ii) any breach of warranty or failure to comply with any covenant contained in this Agreement, including, without limitation, any such misrepresentation, misstatement or omission, or breach of any warranty or covenant, contained herein or any other document submitted by Hsu, against losses, liabilities and expenses for which the Company, or its officers, directors or control persons has not otherwise been reimbursed (including attorneys' fees, judgments, fines and amounts paid in settlement in matters settled in accordance with the provision of the following paragraph) incurred by the Company, or such officer, director or control person in connection with such action, suit or proceeding; provided, however, that Hsu will not be liable in any such case for losses, claims, damages, liabilities or expenses that a court of competent jurisdiction shall have found in a final judgment to have arisen primarily from the gross negligence or willful misconduct of the Company or the party claiming a right to indemnification. In case any proceeding shall be instituted involving any person with respect to whom indemnity may be sought, such person (the "Indemnified Party") shall promptly notify Hsu, and Hsu, upon the request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others Hsu may designate in such proceedings and shall pay as incurred the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel at its own expense, except that Hsu shall pay as incurred the fees and expenses of counsel retained by the Indemnified Party in the event that (i) Hsu and the Indemnified Party shall have mutually agreed to the retention of such counsel or, (ii) the named parties to any such proceeding (including any impleaded parties) include both Hsu and the Indemnified Party and representation of both parties by the same counsel would be inappropriate, in the reasonable opinion of the Indemnified Party, due to actual or potential differing interests between them. Hsu shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Hsu agrees to indemnify the Indemnified Party to the extent set forth in this Agreement. In the event a claim for indemnification as described herein is determined to be unenforceable by a final judgment of a court of competent jurisdiction, then Hsu shall contribute to -6- the aggregate losses, claims, damages or liabilities to which the Company or its officers, directors, agents, employees or controlling persons may be subject in such amount as is appropriate to reflect the relative benefits received by each of the undersigned and the party seeking contribution on the one hand and the relative faults of Hsu and the party seeking contribution on the other, as well as any relevant equitable considerations. The provisions of this Agreement relating to indemnification and contribution shall survive termination of this Agreement and shall be binding upon any successors or assigns of Hsu. 8.
