If the Mandatory Shelf Registration Statement is not automatically effective when filed with the Commission, the Company agrees to use its commercially reasonable efforts to cause the Mandatory Shelf Registration Statement to be declared effective by the Commission within 90 calendar days following the Closing Date.

(i) Effectiveness and Scope. The Company shall use its commercially reasonable efforts to cause the Mandatory Shelf Registration Statement to remain continuously effective until the earliest of (A) the sale pursuant to a registration statement of all of the Registrable Shares covered by the Mandatory Shelf Registration Statement, (B) the sale, transfer or other disposition pursuant to Rule 144 of all of the Registrable Shares covered by the Mandatory Shelf Registration Statement, (C) such time as the Registrable Shares covered by the Mandatory Shelf Registration Statement that are not held by Affiliates of the Company are, in the opinion of counsel to the Company, eligible for resale pursuant to Rule 144 so long as the Company is current in its Exchange Act reporting pursuant to Section 3(b), if so required by Rule 144, (D) such time as all of the Registrable Shares covered by the Mandatory Shelf Registration Statement have been sold to the Company or any of its subsidiaries or (E) the second anniversary of the effective date of the Mandatory Shelf Registration Statement (subject to extension pursuant to Section 5(d)). The Mandatory Shelf Registration Statement shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available to, and requested by, the Holders of the Registrable Shares.

(ii) Underwriting. If any Holder proposes to conduct an Underwritten Offering under the Mandatory Shelf Registration Statement, such Holder shall give notice to the Company and all other Holders of the managing underwriter(s) for such proposed Underwritten Offering, such managing underwriter(s) to be subject to the approval of the Company, such approval not to be unreasonably withheld; provided, however, that the Holders shall not be entitled to effect an Underwritten Offering if the Holders do not propose to offer a minimum of $50 million of Registrable Shares, in the aggregate (determined by multiplying the number of Registrable Shares to be so offered by the participating Holders by the average of the closing price on the NASDAQ Global Select Market for the common stock for the ten trading days preceding the date of such notice), in such Underwritten Offering. In such event, the Company shall enter into an underwriting agreement in customary form with the managing underwriter(s), which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 6, and shall take all such other reasonable actions as are requested by the managing underwriter(s) in order to expedite or facilitate the registration and disposition of the Registrable Shares included in such Underwritten Offering. All Holders proposing to distribute their Registrable Shares through such Underwritten Offering shall enter into an underwriting agreement in customary form with the managing underwriter(s) selected for such underwriting and complete and execute any questionnaires, powers of attorney, indemnities, securities escrow agreements and other documents reasonably required under the terms of such underwriting, and furnish to the Company such information in writing as the Company may reasonably request for inclusion in the Mandatory Shelf Registration Statement; provided, however, that a Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters

-5-

other than representations, warranties or agreements as are customary and reasonably requested by underwriters in similar transactions. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) determine in good faith that marketing factors require a limitation on the number of Registrable Shares to be included in such Underwritten Offering, then the managing underwriter(s) may exclude Registrable Shares requested to be included in such Underwritten Offering, and any Registrable Shares included in the Underwritten Offering shall be allocated to each of the Holders requesting inclusion of their Registrable Shares in such Underwritten Offering on a pro rata basis based on the total number of Registrable Shares then held by each such Holder which is requesting inclusion.

(iii) Selling Stockholder Questionnaires. If a Holder wishes to sell Registrable Shares pursuant to the Mandatory Shelf Registration Statement, it will do so only in accordance with this Section 2(a)(iii). Upon request by the Company, each Holder wishing to sell Registrable Shares pursuant to the Mandatory Shelf Registration Statement agrees to deliver a written notice, substantially in form and substance of Annex C of the Private Placement Memorandum (a “Registration Statement Questionnaire”), to the Company (to the extent such Registration Statement Questionnaire has not been previously provided by such Holder). The Company shall mail the Registration Statement Questionnaire to the Holders no later than the date of initial filing of the Mandatory Shelf Registration Statement with the Commission. No Holder shall be entitled to be named as a selling securityholder in the Mandatory Shelf Registration Statement as of the initial effective date of the Mandatory Shelf Registration Statement, and no Holder shall be entitled to use any Prospectus forming a part thereof for resales of Registrable Shares at any time, unless such Holder has returned a completed and signed Registration Statement Questionnaire to the Company by the deadline for response set forth therein; provided, however, Holders shall have at least three calendar days from the date on which the Registration Statement Questionnaire is first mailed to such Holders to return a completed and signed Registration Statement Questionnaire to the Company; provided, further, that the Company must receive each such Registration Statement Questionnaire at least five Business Days before the commencement of any proposed offering in which such Holder desires to sell any of its Registrable Shares. Notwithstanding the foregoing, (1) upon the request of any Holder that did not return a Registration Statement Questionnaire on a timely basis or did not receive a Registration Statement Questionnaire because it was a subsequent transferee of Registrable Shares after the Company mailed the Registration Statement Questionnaire, the Company shall distribute a Registration Statement Questionnaire to such Holder at the address set forth in the request and (2) upon receipt of a properly completed Registration Statement Questionnaire from such Holder, the Company shall use all commercially reasonable efforts to name such Holder as a selling securityholder in the Mandatory Shelf Registration Statement by means of a pre-effective amendment, by means of a post-effective amendment or, if permitted by the Commission, by means of a prospectus supplement to the Mandatory Shelf Registration Statement; provided, however, that the Company will have no obligation to add Holders to the Mandatory Shelf Registration Statement as selling securityholders more frequently than one time per every 60 calendar days.

(b) Subsequent Shelf Registration for Additional Shares Issued after Effectiveness of the Mandatory Shelf Registration Statement. If any Additional Shares are issued or distributed to Holders after the effectiveness of the Mandatory Shelf Registration Statement, or such Additional Shares were otherwise not included in a prior Registration Statement, then the Company shall as soon as practicable after the issuance or distribution of the Additional Shares file an additional shelf registration statement, which shelf registration statement shall be an “automatic shelf registration statement” as defined under Rule 405, to the extent the Company is eligible to file such automatic shelf registration statement (including the Prospectus, amendments and supplements to such registration statement or Prospectus, including pre- and post-effective amendments, all exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, a “Subsequent Shelf Registration Statement”), covering such Additional Shares on behalf of the Holders thereof in the same manner, and subject to the same provisions in this Agreement as the Mandatory Shelf Registration Statement.

(c) Expenses. The Company shall pay all Registration Expenses in connection with the registration of the Registrable Shares pursuant to this Agreement. Each Holder participating in a registration pursuant to this Section 2 shall bear such Holder’s proportionate share (based on the total number of Registrable Shares sold in such registration) of all discounts and commissions payable to underwriters or brokers and all transfer taxes in connection with a registration of Registrable Shares pursuant to this Agreement and any other expense of the Holders not specifically allocated to the Company pursuant to this Agreement relating to the sale or disposition of such Holder’s Registrable Shares pursuant to any Registration Statement, including but not limited to all Selling Expenses.

With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Shares to the public without registration, the Company agrees to:

(a) make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144, at all times from and after the date hereof;

(b) use its commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required to be filed by the Company under the Securities Act and the Exchange Act, at all times from and after the date hereof; and

In the event of a registration of any Registrable Shares under the Securities Act pursuant to this Agreement, the Company shall indemnify and hold harmless each Selling Holder thereunder, their respective directors, officers, employees, agents and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and their respective directors, officers, employees, agents and managers, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) to which such Selling Holder or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in the light of the circumstances under which such statement is made) contained in a Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, their respective directors, officers, employees, agents and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and their respective directors, officers, employees, agents and managers, for any legal or other expenses reasonably incurred by them in connection

-13-

with investigating or defending any such Loss or actions or proceedings; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, their respective directors, officers, employees, agents and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and their respective directors, officers, employees, agents and managers, in writing specifically for use in the Registration Statement or such other registration statement, free writing prospectus or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder, their respective directors, officers, employees, agents and managers, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and their respective directors, officers, employees, agents and managers, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of Selling Expenses) received by such Selling Holder from the sale of the Registrable Shares giving rise to such indemnification. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and shall survive the transfer of such securities by such Selling Holder.

(c) Notice. Promptly after any indemnified party has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the indemnified party believes in good faith is an indemnifiable claim under this Agreement, the indemnified party shall give the indemnifying party written notice of such claim, but failure to so notify the indemnifying party will not relieve the indemnifying party from any liability it may have to such indemnified party hereunder except to the extent that the indemnifying party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 6 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel or (ii) if the defendants in any such action include both the

-14-

indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable out-of-pocket expenses and fees of such separate counsel and other reasonable out-of-pocket expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, the indemnifying party shall not settle any indemnified claim without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 6 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall a Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of gross proceeds received by such Selling Holder from the sale of Registrable Shares giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 6 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

(a) Additional payments (“Additional Payments”) with respect to the Registrable Shares shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iii) below being herein called a “Registration Default”):

(i) the Mandatory Shelf Registration Statement has not been declared effective within 90 calendar days following the Closing Date;

-15-

(ii) the Mandatory Shelf Registration Statement has not been filed by the date specified in Section 2(a);

(iii) the Company fails, with respect to a Holder that supplies a Registration Statement Questionnaire described in Section 2(a)(iii), to cause an amendment to the already effective Mandatory Shelf Registration Statement to be filed or, if permitted by the Commission, to prepare a Prospectus supplement to the Mandatory Shelf Registration Statement and distribute such supplement to Holders, in each case within the time period set forth in Section 2(a)(iii) to name such Holder as an additional selling securityholder; or

(iv) the Mandatory Shelf Registration Statement is declared effective by the Commission but the Mandatory Shelf Registration Statement thereafter ceases to be effective during the period contemplated by Section 2(a)(i) and the Company fails to cure the Mandatory Shelf Registration Statement within five Business Days by a post-effective amendment or a report filed pursuant to the Exchange Act.

Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the Company’s control or pursuant to operation of law or as a result of any action or inaction by the Commission.

(b) Additional Payments shall accrue on the Registrable Shares for each such day from and including the date on which any such Registration Default occurs to but excluding the date on which all such Registration Defaults have been cured, at a rate of 1.0% per month (or 12.0% per annum) of the price per share at which the Initial Common Shares were offered in the Third Party Sale multiplied by the aggregate number of Initial Common Shares that were held of record by such Holder prior to the Registration Default, which shall be payable monthly in arrears on the last day of the month in cash; provided, however, that in no event shall be the Company be required to pay to any Holder pursuant to this Section 7 an amount greater than (i) an amount equal to 6.0% of the price per share at which the Initial Common Shares were offered in the Third Party Sale, multiplied by (ii) the aggregate number of Initial Common Shares that were held of record by such Holder prior to the Registration Default. The amount of Additional Payments will be determined on the basis of a 360-day year comprised of twelve 30-day months, and the actual number of days on which Additional Payments accrued during such period. In the case of a Registration Default described in Section 7(a)(ii), the Company’s obligation to pay Additional Payments extends only to the affected Registrable Shares. Other than the obligation of payment of any Additional Payments in accordance with the terms hereof, the Company will have no other liabilities for monetary damages with respect to its registration obligations. With respect to each Holder, the Company’s obligations to pay Additional Payments remain in effect only so long as the securities held by the Holder are Registrable Shares.

(c) A Registration Default referred to in Section 7(a)(iii) shall be deemed not to have occurred and be continuing, and no Additional Payments shall accrue as a result thereof, in relation to the Mandatory Shelf Registration Statement or the related prospectus if (i) (A) such

-16-

Registration Default has occurred solely as a result of the occurrence of material events with respect to the Company that would need to be described in such Mandatory Shelf Registration Statement or the related prospectus or (B) the Registration Default relates to any information supplied or failed to be supplied by a Holder of Registrable Shares and (ii) the Company is proceeding promptly and in good faith to amend or supplement the Mandatory Shelf Registration Statement and related prospectus to describe such events or include such information.

The Company shall have no further obligations pursuant to this Agreement at such time as no Registrable Shares are outstanding; provided, however, that the Company’s obligations under Sections 6 and 10 of this Agreement shall remain in full force and effect following such time.

From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the then outstanding Registrable Shares, enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or prospective holder to include such securities in the Mandatory Shelf Registration Statement filed pursuant to the terms hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of Registrable Shares of the Holders that is included.

(a) Amendments and Waivers. This Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, without the written consent of the Company and Holders beneficially owning a majority of the then outstanding Registrable Shares; provided, however, that for purposes of this Agreement, Registrable Shares owned, directly or indirectly, by an Affiliate of the Company shall not be deemed to be outstanding. Notwithstanding the foregoing, a waiver or consent to or departure from the provisions hereof with respect to a matter that relates exclusively to the rights of a Holder whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders may be given by such Holder; provided that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence.

(b) Notices. All notices and other communications, provided for or permitted hereunder shall be made in writing and delivered by facsimile or electronic mail (with receipt confirmed), overnight courier or registered or certified mail, return receipt requested, or by telegram, addressed as follows:
