2. Registration Rights.

(a) Piggyback Registration. If at any time within the 12-month period following the Closing Date, the Company proposes to register any of its securities under the Securities Act for sale to the public on its own account or the account of any of its security holders (other than a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales), then the Company shall give written notice of such proposed registration to the Holders. Within ten (10) days after the Company’s notice is deemed given pursuant to Section 9(b),

any Holder who desires to include Registrable Securities in such proposed registration shall deliver to the Company a written request specifying the number of Registrable Securities that such Holder desires to include in the proposed registration. Upon receipt of such written request, the Company shall, subject to Section 2(b), Section 2(c) and Section 2(d), use its commercially reasonable efforts to include in such proposed registration (and any related qualification under “blue sky” laws) all Registrable Securities of the Holder requested to be registered. If any Holder decides not to include all of its Registrable Securities in a registration by the Company pursuant to this Section 2(a), the registration rights of such Holder under this Section 2(a) shall continue to apply to subsequent registrations with respect to Registrable Securities retained by such Holder, all upon the terms and conditions set forth in this Agreement. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2(a) prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. Any proceeds attributable to Escrow Shares shall remain subject to the terms and conditions of the Escrow Agreement.

(b) Participation in Underwritten Registrations. No Holder may participate in any underwritten registration hereunder unless such Holder (a) enters into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company or other Persons entitled to select such underwriters and agrees to sell its Registrable Securities on the basis of the terms in such underwriting agreement, and (b) completes and executes all questionnaires, lock-up agreements, powers of attorney, indemnities, custody agreements and other documents required under the terms of such underwriting agreement. If a Holder who has requested inclusion in an underwritten offering does not agree to the terms of any such underwriting, such Holder and such Holder’s securities shall be excluded therefrom and from the Registration Statement by written notice from the Company or the underwriter.

(c) Senior Registration Rights. Notwithstanding anything contained herein, the registration rights of the Holders set forth in this Agreement shall be subordinate to the registration rights of the Senior Holders under the Senior Registration Rights Agreement and, in the event of any reduction in the number of shares to be registered in a proposed registration, the number of shares of Registrable Securities to be included in the proposed registration shall be reduced prior to any reduction in the number of shares to be registered on the account of the Senior Holders in such registration to the extent required by, and in accordance with, the Senior Registration Rights Agreement.

(d) Postponement of Effectiveness. Upon receipt of any notice (a “Suspension Notice”) from the Company of the happening of any event which makes any statement made or incorporated in a Registration Statement or a related prospectus untrue or which requires the making of any changes in such Registration Statement or prospectus (or the information incorporated therein) so that they will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances under which they were made not misleading, each Holder of Registrable Securities registered under such Registration Statement shall forthwith discontinue disposition of Registrable Securities pursuant to such Registration Statement until such Holder’s receipt of the copies of the supplemented or amended prospectus or until it

is advised in writing (the “Advice”) by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated by reference in the prospectus. In the event that the Company shall give any Suspension Notice, the Company shall use commercially reasonable efforts to render the Advice and end the suspension period as promptly as reasonably practicable. The Company shall prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective and in compliance with applicable laws until such time as all Registrable Securities have been sold pursuant to the Registration Statement; provided, however, the Company shall not be required to keep such Registration Statement effective for more than 120 days (or such shorter period which will terminate when all Registrable Securities covered by such Registration Statement have been sold, but not prior to the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable) (the first to occur, the “Expiration Date”).

The Company may require each seller of Registrable Securities as to which any registration is being effected to furnish to the Company such information as is required to be included with respect to such seller in a Registration Statement including information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities. Such information may be requested pursuant to an investor questionnaire prepared for such purpose.

Each Holder agrees that, upon receipt of any notice from the Company of a Suspension Notice as set forth in this Section 2(d), such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or prospectus until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by this Section 2(d) hereof, or until it receives Advice that the use of the prospectus may be resumed and such Holder has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus. Further, each Holder acknowledges and agrees that its receipt of a Suspension Notice may constitute material, non-public information under federal and/or applicable state securities laws.

3. Registration Procedures.

With respect to any registration which includes Registrable Securities held by a Holder, the Company shall:

(a) prepare and file with the Commission a Registration Statement on the appropriate form under the Securities Act with respect to such securities, which form shall comply in all material respects with the requirements of the applicable form and include all financial statements required by the Commission to be filed therewith, and use its commercially reasonable efforts to cause such Registration Statement to become and remain effective until completion of the proposed offering;

4. Indemnification.

(a) Indemnification by the Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the members, owners, partners, officers, directors, employees, agents, successors and assigns of each Holder, and each Person controlling such Holder within the meaning of Section 15 of the Securities Act (each a “Holder Indemnified Person”), against any losses, claims, damages, or liabilities (individually and collectively, the “Liability”) (joint or several) to which such Holder Indemnified Person may become subject under the Securities Act or otherwise, insofar as such Liability (or actions or proceedings in respect thereof) arises out of or is based upon any of the following statements, omissions or violations by the Company (collectively a “Company Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act pursuant to this Agreement, including any final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation of the Securities Act, or any applicable federal or state securities law or any rule or regulation promulgated under the Securities Act, or any applicable federal or state securities law in connection with the offering covered by such Registration Statement; provided however, that the Company shall not be required to indemnify any Holder Indemnified Person against any Liability to the extent that such Liability (or actions or proceedings in respect thereof) arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished by such Holder Indemnified Person expressly for use in connection with a Registration Statement, including any final prospectus contained therein or any amendments or supplements thereto; provided further, that the Company shall not be required to indemnify any Holder Indemnified Person against Liability to the extent that such Liability (or actions or proceedings in respect thereof) arises out of or is based upon an untrue statement or omission made in any preliminary prospectus if (i) such Holder Indemnified Person failed to send or deliver a copy of the final prospectus with or prior to the delivery of written confirmation of the sale by such Holder to the Person asserting the claim from which such Liabilities arise, and (ii) the final prospectus would have corrected such untrue statement or such omission; provided further, that the Company shall not be required to indemnify any Holder Indemnified Person against Liability to the extent that such Liability (or actions or proceedings in respect thereof) arises out of or is based upon an untrue statement or omission in any prospectus if (x) such untrue statement or omission is corrected in an amendment or supplement to such prospectus, and (y) having previously been furnished by or on behalf of the Company with copies of such prospectus as so amended or supplemented, such Holder Indemnified Person thereafter fails to deliver such prospectus as so amended or supplemented prior to or concurrently with the sale of a Registrable Security to the Person asserting the claim from which such Liabilities arise; and provided further, that the indemnity agreement contained in this Section 4(a) shall not apply to amounts paid in settlement if such settlement is effected without the consent of the Company (which such consent shall not be unreasonably withheld). The Company’s indemnification obligations shall survive any transfer by such Holder of its Registrable Securities.

(b) Indemnification by Holders. To the extent permitted by law, each Holder agrees to indemnify and hold harmless the Company, each of the officers, directors, employees, agents, successors and assigns of the Company, any other stockholder selling shares of Common Stock in such registration, and each Person controlling the Company or such other stockholder within the meaning of Section 15 of the Securities Act the Company (each a “Company Indemnified Person”), from and against any Liability (joint or several) to which any such Company Indemnified Person may become subject under the Securities Act or otherwise, insofar as such Liability (or actions or proceedings in respect thereof) arises out of or is based upon any of the following statements, omissions or violations by the Holder (collectively a “Holder Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act pursuant to this Agreement, including any final prospectus contained therein or any amendments or supplements thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, in each case to the extent that such untrue statement or alleged untrue statement or omission or alleged omission occurs in reliance upon and conformity with written information furnished by such Holder, any of such Holder’s officers, directors, partners, legal counsel or accountants or any Person controlling such Holder expressly for use in connection with a Registration Statement, including any final prospectus contained therein or any amendments or supplements thereto; provided however, that the indemnity agreement contained in this Section 4(b) shall not apply to amounts paid in settlement if such settlement is effected without the consent of the Holder (which such consent shall not be unreasonably withheld). The amount recoverable by the Company from any Holder under this indemnification provision together with any amounts recovered from such Holder under Section 4(d) shall not exceed the amount of net proceeds received by such Holder from the sale of Registrable Securities in connection with any such registration, except in the case of willful fraud, or intentional misstatement or omission by such Holder. Each Holder’s indemnification obligations shall survive any transfer by such Holder of its Registrable Securities.

(c) Conduct of Indemnification Proceedings. In the event any Company Indemnified Person or Holder Indemnified Person ( each an “Indemnified Person”) receives a complaint, claim or other notice of any liability or action, giving rise to a claim for indemnification under Sections 4(a) or 4(b) above, the Person claiming indemnification under such paragraphs shall promptly notify the Person against whom indemnification is sought (the “Indemnifying Person”) of such complaint, notice, claim or action, and the Indemnifying Person shall have the right to investigate and defend any such loss, claim, damage, liability or action; provided however, that the failure to promptly give notice shall not relieve the Indemnifying Person from any Liability except to the extent that it is materially prejudiced by the failure or delay of the Indemnified Person in giving such notice. If any such complaint, claim or other notice of any Liability or action is brought against any Indemnified Person and it notifies the Indemnifying Person of its commencement, the Indemnifying Person will be entitled to participate in and, to the extent that it elects by delivering written notice to the Indemnified Person promptly after receiving notice of the commencement of the action from the Indemnified Person, jointly with any other Indemnifying Person similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the Indemnified Person, and after notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense, the Indemnifying Person shall not be liable to the Indemnified Person for any legal or other expenses except as provided below. The Indemnified Person shall have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such

counsel shall be at the expense of the Indemnified Person unless (i) the Indemnified Person has reasonably concluded (based on advice of legal counsel) that there may be legal defenses available to it or other Indemnified Persons different from or in addition to those available to the Indemnifying Person or Persons, or (ii) a conflict or potential conflict exists (based on advice of counsel to the Indemnified Person) between the Indemnified Person and the Indemnifying Person (in which case the Indemnifying Person shall not have the right to direct the defense of such action on behalf of the Indemnified Person), in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the Indemnifying Person or Persons. The Indemnifying Person or Persons shall not, unless a conflict of interest exists among the Indemnified Persons, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any time for all such Indemnified Persons. All such fees, disbursements and other charges shall be reimbursed by the Indemnifying Person promptly as they are incurred. An Indemnifying Person shall not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Person shall, without the prior written consent of each Indemnified Person, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 4 (whether or not any Indemnified Person is a party thereto) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Person from all liability arising or that may arise out of such claim, action or proceeding.

(d) Contribution. If the indemnification provided for in this Section 4 from the Indemnifying Person is held by a court of competent jurisdiction to be unavailable to an Indemnified Person hereunder in respect of any Liability or expenses referred to herein, then the Indemnifying Person, in lieu of indemnifying such Indemnified Person, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Liability or expenses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Person and Indemnified Persons in connection with the actions which resulted in such Liability or expenses, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Person and Indemnified Persons shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact, has been made by, or relates to information supplied by, such Indemnifying Person or Indemnified Persons, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The amount recoverable by the Company from any Holder under this provision together with any amounts recovered from such Holder under Section 4(b) shall not exceed the amount of net proceeds received by such Holder from the sale of Registrable Securities in connection with any such registration, except in the case of willful fraud, or intentional misstatement or omission by such Holder.

(e) The amount paid by an Indemnifying Person or payable to an Indemnified Person as a result of the Liabilities or expenses referred to in this Section 4 shall be deemed to include, subject to limitations set forth above, any legal or other expenses, in each case, reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim. The indemnification and contribution provided for in this Section 4 shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Persons or any other officer, director, employee, agent or controlling person of the Indemnified Persons.

5. Registration Expenses.

All expenses incurred in connection with effecting the registrations provided for in Section 2 including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel for the Company, expenses of any audits incident to or required by any such registration and expenses of complying with the state securities or “blue sky” laws of any jurisdictions but excluding any Selling Expenses (all of such expenses referred to as “Registration Expenses”), shall be paid by the Company whether or not the Registration Statement to which such Registration Expenses relate becomes effective; provided, however, that the Company shall not be liable (and shall be reimbursed by the participating Holders) for any Registration Expenses if such registration statement does not become effective as a result of the actions or omissions of the Holders participating in the registration. All Selling Expenses relating to securities registered on behalf of the Holders shall be paid by the Holders.

6. Lock-Up.

Each Holder agrees not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of or otherwise dispose of or transfer any shares of capital stock of the Company held by it during the period commencing ten (10) days prior to the effective date of a registration statement related to an underwritten public offering of the Company’s securities and ending one hundred and eighty (180) days following the effective date of such registration statement (or for such shorter period of time as is sufficient and appropriate in the opinion of the managing underwriter or for such longer period of time as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto) and, if so requested by the Company or managing underwriter, each Holder shall execute an agreement with respect to the foregoing.

7. Rule 144.

The Company covenants that it will timely file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder and to take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act subject to the limitations of the exemptions provided by Rule 144 or any similar rule or regulation hereafter adopted by the Commission. Upon request, the Company will provide to a Holder written certification of its compliance with the reporting requirements of Rule 144.

8. Restrictions on Transfer.

(a) The Holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Registrable Securities, or any beneficial interest therein, unless and until:

(i) There is then in effect a Registration Statement under the Securities Act covering such proposed disposition and the disposition is made in accordance with the Registration Statement; or

(ii) The Holder may dispose of the Registrable Securities in compliance with Rule 144; or

(iii) The Holder shall have given prior written notice to the Company of the Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, and the Holder shall have furnished the Company, at the Holder’s expense, with an opinion of counsel reasonably satisfactory to the Company to the effect that such disposition will not require registration of such Registrable Securities under the Securities Act whereupon the holder of such Registrable Securities shall be entitled to transfer such Registrable Securities in accordance with the terms of the notice delivered by the Holder to the Company.

(b) Notwithstanding the provisions of Section 8(a), no such Registration Statement or opinion of counsel shall be necessary for (i) a transfer not involving a change in beneficial ownership or for estate planning purposes (including, without limitation, a transfer made during Holder’s lifetime or on death by will or intestacy to his spouse, child (natural or adopted), or any other direct lineal descendant of such Holder (or his spouse) (all of the foregoing collectively referred to as “family members”), or any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the ownership interests of which are owned wholly by, such Holder or any such family members), or (ii) transactions involving the distribution without consideration of Registrable Securities by any Holder to (x) a parent, subsidiary or other affiliate of the Holder, if the Holder is a corporation, (y) any of the Holder’s partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of the Holder’s partners, members or other equity owners or retired partners, retired members or other equity owners, or (iii) transfers in compliance with Rule 144; provided, in each case (other than (iii)), that the Holder shall give written notice to the Company of the Holder’s intention to effect such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition and the transferor delivers an executed copy of the Instrument of Accession attached hereto as Exhibit A.

(c) Each certificate representing Registrable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws):

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.
