(THE “ISSUER”) AND THE ISSUER’S SECURITYHOLDERS NAMED THEREIN, AS AMENDED.

A COPY OF SUCH REGISTRATION RIGHTS AND LOCK UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

2.3.1Prior Notice. Prior to the transfer of any Common Stock permitted by Section 2.2, the Holder of such Common Stock shall give the Company at least three (3) Business Days’ prior notice of such permitted transfer, other than in the case of transfers upon the death of an individual.

Prior to the consummation of any such permitted transfer, or prior to any transfer pursuant to which rights and obligations of the transferor under this Agreement are assigned in accordance with the terms of this Agreement, the transferring Holder shall cause the transferee to agree to be bound by the terms and conditions of this Agreement and shall provide any documents required by the transfer agent for the Common Stock to consummate such transfer.

2.3.2Null and Void.

2.3.4Early Release of Lock-Up Restrictions.

3. REGISTRATION RIGHTS.

3.1 Shelf Registration.

3.1.1Initial Filing. As soon as practicable following the Closing, but no later than the Filing Date, the Company shall prepare and file with the Commission a Registration Statement for Shelf Registration on Form S-1 covering the resale of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act. Subject to the terms of this Agreement, the Company shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as practicable after the filing thereof, but in any event prior to the applicable Effectiveness Date, and shall use its commercially reasonable efforts to keep such Registration Statement continuously effective under the Securities Act until all Registrable Securities covered by such Registration Statement have been sold, or may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 promulgated under the Securities Act, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 promulgated under the Securities Act, as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the transfer agent and the affected Holders (the “Effectiveness Period”). The Company shall telephonically request effectiveness of the Registration Statement as of 5:00 p.m. New York City time on a Business Day. The Company shall promptly notify the Holders by e-mail of the effectiveness of the Registration Statement on the same Business Day that the Company telephonically confirms effectiveness with the Commission. The Company shall, no later than the second Business Day after the effective date of such Registration Statement, file a final Prospectus with the Commission as required by Rule 424 of the Securities Act.

6

3.1.2Subsequent Shelf Registration. If any Shelf Registration Statement ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall use its commercially reasonable efforts to, as promptly as is reasonably practicable, cause such Shelf Registration Statement to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration Statement”) registering the resale of all Registrable Securities (determined as of two (2) business days prior to such filing). If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof and (ii) keep such Subsequent Shelf Registration Statement continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein, and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a Holder, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, any available Shelf Registration Statement (including by means of a post-effective amendment) or by filing a Subsequent Shelf Registration Statement and causing the same to become effective as soon as practicable after such filing and such Shelf Registration Statement or Subsequent Shelf Registration Statement shall be subject to the terms hereof; provided, however, the Company shall only be required to cause such additional Registrable Securities to be so covered once annually after inquiry of the Holders.

3.1.3Commission Cutback. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater portion of Registrable Securities), the number of Registrable Securities to be registered shall be reduced on a on a pro rata basis based on the total number of Registrable Securities held by such Holders (such proportion is referred to herein as “Pro Rata”). In the event of a reduction hereunder, the Company shall give the Holder, as applicable, at least five (5) Business Days prior written notice along with the calculations as to such Holder’s allotment. Promptly after such SEC Guidance is no longer applicable with respect to some or all of the remaining unregistered Registrable Securities, the Company shall file an additional Registration Statement in accordance with this Section 3 with respect to such shares.

3.1.3 Selling Stockholder Questionnaire. Each Holder agrees to furnish to the Company a completed Selling Stockholder Questionnaire, in the form set forth as Exhibit B hereto, within five (5) Business Days following the date of this Agreement. Each Holder further acknowledges and agrees that it shall not be entitled to be named as a selling security holder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time unless such Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire. If a Holder of Registrable Securities returns a Selling Stockholder Questionnaire after the deadline specified in the previous sentence, the Company shall use its commercially reasonable efforts to take such actions as are required to name such Holder as a selling security holder in the Registration Statement or any pre-effective or post-effective amendment thereto and to include (to the extent not theretofore included) in the Registration Statement the Registrable Securities identified in such late Selling Stockholder Questionnaire; provided that the Company shall not be required to file an additional Registration Statement solely for such shares.

7

3.2 Demand Registration.

3.2.1Request for Registration. At any time and from time to time on or after the date of this Agreement, the Holders of ten percent (10%) of the Registrable Securities may make a written demand for registration under the Securities Act of all or part of their Registrable Securities, as the case may be (a “Demand Registration”). Any demand for a Demand Registration shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will within ten (10) days of the Company’s receipt of the Demand Registration notify, in writing, all other Holders of Registrable Securities of the demand, and each Holder of Registrable Securities who wishes to include all or a portion of such Holder’s Registrable Securities in the Demand Registration (each such Holder including shares of Registrable Securities in such Demand Registration, a “Demanding Holder”) shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such notice from a Demanding Holder(s), the Demanding Holder(s) shall be entitled to have their Registrable Securities included in the Demand Registration, and the Company shall effect, as soon as reasonably practicable thereafter, but not more than forty five (45) days after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders pursuant to the Demand Registration, subject to Section 3.2.4 and the provisos set forth in Section 4.1.1. The Company shall not be obligated to effect more than an aggregate of four (4) Demand Registrations under this Section 3.2.1 in respect of all Registrable Securities; provided that the Initial Holders shall have the right to demand at least one (1) of such four (4) Demand Registrations.

3.2.2Effective Registration. Notwithstanding the provisions of Section 3.2.1 above, a Registration pursuant to a Demand Registration will not count as a Demand Registration unless and until (i) the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto and (iii) all of the Registrable Securities requested by the Demanding Holders to be registered on behalf of the Demanding Holders in such Form S-1 Registration have been sold, in accordance with Section 4.1 of this Agreement; provided, however, that the Company shall not be obligated to file a another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

3.2.3Underwritten Offering. If a majority-in-interest of the Demanding Holders so advise the Company as part of their written demand for a Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering. In such event, the right of any Demanding Holder to include its Registrable Securities in such registration shall be conditioned upon such Demanding Holder’s participation in such Underwritten Offering and the inclusion of such Demanding Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through such Underwritten Offering pursuant to this Section 3.2.3 shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Underwritten Offering by a majority- in-interest of the Demanding Holders participating in the Demand Registration.

3.2.4Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an Underwritten Offering, in good faith, advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other Common Stock or other securities which the Company desires to sell and the Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such Underwritten Offering (such maximum dollar amount or maximum number of

8

shares, as applicable, the “Maximum Number of Shares” ), then the Company shall include in such Demand Registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (Pro Rata in accordance with the number of shares that each such Demanding Holder has requested be included in such Registration, regardless of the number of shares held by each such Demanding Holder) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i), the Registrable Securities of Holders exercising their rights to register their Registrable Securities that can be sold without exceeding the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares.

A majority-in-interest of the Demanding Holders shall have the right to withdraw from a Registration pursuant to a Demand Registration for any or no reason whatsoever by giving written notice to the Company and the Underwriter or Underwriters of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from a proposed Underwritten Offering relating to a Demand Registration, then such registration shall not count as a Demand Registration provided for in Section 3.2. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for all fees and expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this Section 3.2.5.

The Company shall, in good faith, cause such Registrable Securities to be included in such Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All Holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected by the Company for such Piggy-Back Registration.

3.3.2Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an Underwritten Offering advises the Company and the Holders of Registrable Securities in writing that the dollar amount or number of Common Stock which the Company desires to sell, taken together with the Common Stock, if any, as to which Registration has been demanded pursuant to written contractual arrangements with persons other than the

Holders of Registrable Securities hereunder, the Registrable Securities as to which Registration has been requested under this Section 3.3, and the Common Stock, if any, as to which Registration has been requested pursuant to the terms hereof exceeds the Maximum Number of Shares, then the Company shall include in any such Registration:

a)If the Registration is undertaken for the Company’s account: (A) first, the Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the Common Stock or other securities, if any, comprised of Registrable Securities as to which Registration has been requested pursuant to the terms hereof, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares;

b)If the Registration is a “demand” registration undertaken at the demand of persons other than the Holders of Registrable Securities, (A) first, the Common Stock or other securities for the account of the demanding persons that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the Common Stock or other securities comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares.

Any Holder of Registrable Securities shall have the right to withdraw, for any reason or for no reason whatsoever, such Holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of their intention to withdraw from such Piggy-Back Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggy-Back Registration. The Company (whether on its own good-faith determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement filed with the Commission with respect to a Piggy-Back Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the Holders of Registrable Securities in connection with such Piggy-Back Registration.

3.3.4Unlimited Piggy-Back Registration Rights.

The Holders of Registrable Securities may at any time and from time to time, request in writing that the Company register the resale of any or all of such Registrable Securities on Form S-3 or any similar short-form registration which may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Upon receipt of such written request, the Company will promptly give written notice of the proposed Registration to all other Holders of Registrable Securities, and, as soon as practicable thereafter, effect the Registration of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable

10

Securities or other securities of the Company, if any, of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to this Section 3.4 if Form S-3 is not available for such offering. Registrations effected pursuant to this Section 3.4 shall not be counted as Demand Registrations effected pursuant to Section 3.2.

3.5 Block Trades; Other Coordinated Offerings.

3.5.1Notwithstanding any other provision of this Section 3.5, at any time and from time to time when an effective Shelf Registration is on file with the Commission, if a Demanding Holder wishes to engage in (a) an underwritten registered offering (whether firm commitment or otherwise) not involving a “road show” or other substantial marketing efforts prior to pricing (commonly referred to as a “Block Trade”) or (b) an otherwise coordinated “at the market” or similar registered offering through a broker, sales agent or distribution agent, whether as agent or principal (an “Other Coordinated Offering”), in each case, with a total offering price reasonably expected to exceed, in the aggregate, either (x) $10 million or (y) all remaining Registrable Securities held by the Demanding Holder, then such Demanding Holder shall notify the Company of the Block Trade or Other Coordinated Offering at least five (5) business days prior to the day such Block Trade or Other Coordinated Offering, as applicable, is expected to commence, and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Block Trade or Other Coordinated Offering; provided that the Demanding Holders representing a majority of the Registrable Securities wishing to engage in the Block Trade or Other Coordinated Offering shall use commercially reasonable efforts to work with the Company and any Underwriters, brokers, sales agents, or placement agents prior to making such request in order to facilitate preparation of the registration statement, prospectus, and other offering documentation related to the Block Trade or Other Coordinated Offering.

3.5.2The Company may facilitate a Block Trade or Other Coordinated Offering if it determines that sufficient shares shall be traded by any Holder or Holders that would be more efficiently traded as a block trade.

3.5.3Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade or Other Coordinated Offering, a majority-in-interest of the Demanding Holders initiating such Block Trade or Other Coordinated Offering shall have the right to submit a notice to the Company and the Underwriter(s) if any, of their intention to withdraw from such Block Trade or Other Coordinated Offering. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Block Trade or Other Coordinated Offering prior to its withdrawal under this Section 3.5.3.

3.5.4Notwithstanding anything to the contrary in this Agreement, Section 3.3 shall not apply to a Block Trade or Other Coordinated Offering initiated by a Demanding Holder pursuant to this Section 3.5.

3.5.5The Company shall have the right to select the Underwriters, and brokers, sale agents, or placement agents (if any) for such Block Trade or Other Coordinated Offering, in each case, which shall consist of one or more reputable nationally recognized investment bank.

4.1.2Copies. The Company shall, at least five (5) days prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration Statement (including each preliminary prospectus), and such other documents as the Holders of Registrable Securities included in such Registration or legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders.

4.1.4Notification. After the filing of a Registration Statement, the Company shall promptly, and in no event more than two (2) business days after such filing, notify the Holders of Registrable Securities included in such Registration Statement of such filing, and shall further notify such Holders promptly and confirm such advice in writing in all events within two (2) business days of the occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment to such Registration Statement becomes effective; (iii) the issuance or threatened issuance by the Commission of any stop order (and the Company shall take all actions required to prevent the entry of such stop order or to remove it if entered); and (iv) any request by the Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will not contain an 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 not misleading, and promptly make available to the Holders of Registrable Securities included in such Registration Statement any such supplement or amendment; except that before filing with the Commission a Registration Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish to the Holders of Registrable Securities included in such Registration Statement and to the legal counsel for any such Holders, copies of all such documents proposed to be filed sufficiently in advance of filing to provide such Holders and legal counsel with a reasonable opportunity to review such documents and comment thereon, and the Company shall not file any Registration Statement or prospectus or amendment or supplement thereto, including documents incorporated by reference, to which such Holders or their legal counsel shall object.

In the event no legal opinion is delivered to any Underwriter, the Company shall furnish to each Holder of Registrable Securities included in such Registration Statement, at any time that such Holder elects to use a prospectus, an opinion of counsel to the Company to the effect that the Registration Statement containing such prospectus has been declared effective and that no stop order is in effect.

4.1.10Earnings Statement. The Company shall comply with all applicable rules and regulations of the Commission and the Securities Act, and make available to its stockholders, as soon as practicable, an earnings statement covering a period of twelve (12) months, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

13

Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4.1.4(iv), or, in the case of a resale registration on Form S-3 pursuant to Section 3.3 hereof, upon any suspension by the Company, pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors, of the ability of all “insiders” covered by such program to transact in the Company’s securities because of the existence of material non-public information, each Holder of Registrable Securities included in any registration shall immediately discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Holder receives the supplemented or amended prospectus contemplated by Section 4.1.4(iv) or the restriction on the ability of “insiders” to transact in the Company’s securities is removed, as applicable, and, if so directed by the Company, each such Holder will deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

4.3Registration Expenses. The Company shall bear all costs and expenses incurred in connection with any Shelf Registration pursuant to Section 3.1, Demand Registration pursuant to Section 3.2, any Piggy-Back Registration pursuant to Section 3.3, and any registration on Form S-3 effected pursuant to Section 3.3.5, and all expenses incurred in performing or complying with its other obligations under this Agreement, whether or not the Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees; (ii) fees and expenses of compliance with securities or “blue sky” laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities); (iii) printing expenses; (iv) the fees and expenses incurred in connection with the listing of the Registrable Securities as required by Section 4.1.11; (v) Financial Industry Regulatory Authority fees; (vi) fees and disbursements of counsel for the Company and fees and expenses for independent certified public accountants retained by the Company (including the expenses or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 4.1.9); and (vii) the reasonable fees and expenses of any special experts retained by the Company in connection with such registration.

Additionally, in an Underwritten Offering, all selling stockholders and the Company shall bear the incremental expenses of the Underwriter pro rata in proportion to the respective amount of shares each is selling in such offering.

4.4Information. The Holders of Registrable Securities shall provide such information as may reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 3 and in connection with the Company’s obligation to comply with Federal and applicable state securities laws.

14

In addition, the Holders of Registrable Securities shall comply with all prospectus delivery requirements under the Securities Act and applicable SEC regulations.

4.5Legend Removal Obligations. In connection with the written request of any Holder, the Company shall remove any restrictive legend included on the certificates (or, in the case of book-entry shares, any other instrument or record) representing such Holder’s or Permitted Transferee’s ownership of Registrable Securities, and promptly issue a certificate (or evidence of the issuance of securities in book-entry form) without such restrictive legend or any other restrictive legend to the Holder of the applicable shares of Registrable Securities upon which it is stamped, if (i) such Registrable Securities are registered for resale under the Securities Act and such Registration Statement for such Registrable Securities has not been suspended under the Securities Act, the Exchange Act or the rules and regulations of the Commission promulgated thereunder, (ii) such Registrable Securities are sold or transferred pursuant to Rule 144 promulgated under the Securities Act, or (iii) such Registrable Securities are eligible for sale pursuant to Section 4(a)(1) of the Securities Act or Rule 144 without volume or manner-of- sale restrictions. Following the earlier of (A) the effective date of a Registration Statement registering such Registrable Securities or (B) Rule 144 becoming available for the resale of such Registrable Securities without volume or manner-of-sale restrictions, the Company upon the written request of the Holder or its Permitted Transferee, shall instruct the Company’s transfer agent to remove the legend from such Registrable Securities (in whatever form) and shall cause the Company’s counsel to issue any legend removal opinion required by the transfer agent. Any reasonable and documented fees (with respect to the transfer agent, the Company’s counsel, or otherwise) associated with the removal of such legend shall be borne by the Company. If a legend is no longer required pursuant to the foregoing, the Company will, as soon as practicable following the delivery by any Holder or its Permitted Transferee to the Company or the transfer agent (with notice to the Company) of a legended certificate (if applicable) representing such Registrable Securities and, to the extent such sale is not pursuant to an effective registration statement, such other documentation as reasonably requested by the Company, deliver or cause to be delivered to the Holder of such Registrable Securities a certificate representing such Registrable Securities (or evidence of the issuance of such Registrable Securities in book-entry form) that is free from all restrictive legends; provided that, notwithstanding the foregoing, the Company will not be required to deliver any opinion, authorization, certificate, or direction to remove the restrictive legend pursuant to this Section 4.5 if (x) removal of the legend would result in or facilitate transfer of securities in violation of applicable law or (y) following receipt of instruction from the Company, the transfer agent refuses to remove the legend.

4.6Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to EDGAR shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 4.6. The Company further covenants that it shall 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 shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

5. INDEMNIFICATION AND CONTRIBUTION.

5.1Indemnification by the Company. The Company agrees to indemnify and hold harmless each Holder of Registrable Securities, and each of their respective officers, employees, Affiliates, directors, partners, members, attorneys, and agents, and each person, if any, who controls a Holder of Registrable Securities (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “Holder Indemnified Party” ), from and against any expenses, losses, judgments, claims, damages, or liabilities, whether joint or several, arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Holder Indemnified Party for any legal and any other expenses reasonably incurred by such Holder Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability, or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss, claim, damage, or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling Holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their officers, Affiliates, directors, partners, members, and agents and each person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 5.1.

5.2Indemnification by Holders of Registrable Securities. Each selling Holder will, in the event that any Registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling Holder, indemnify and hold harmless the Company, each of its directors and officers and each Underwriter (if any), and each other selling Holder and each other person, if any, who controls another selling Holder or such Underwriter within the meaning of the Securities Act, against any losses, claims, judgments, damages, or liabilities, whether joint or several, insofar as such losses, claims, judgments, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus, or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by such selling Holder expressly for use therein, and shall reimburse the Company, its directors and officers, and each other selling Holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability, or action. Each selling Holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling Holder.

5.3Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage, or liability or any action in respect of which indemnity may be sought pursuant to Section 5.1 or 5.2, such person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder, notify such other person (the “Indemnifying Party” ) in writing of the loss, claim, judgment, damage, liability, or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought

16

against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

5.4 Contribution.

5.4.1If the indemnification provided for in the foregoing Sections 5.1, 5.2, and 5.3 is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability, or action referred to herein, 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, claim, damage, liability, or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability, or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party 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 relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

5.4.2The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding Section 5.4.1.

5.4.3The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability, or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5.4, no Holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions, or taxes) actually received by such Holder from the sale of Registrable Securities which gave rise to such contribution obligation. 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 was not guilty of such fraudulent misrepresentation.

5.5Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Party or any officer, director, or controlling person of such Indemnified Party and shall survive the transfer of securities.

6.RULE 144. The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the Holders of Registrable Securities

17

may reasonably request, all to the extent required from time to time to enable such Holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

7. MISCELLANEOUS.

7.1Other Registration Rights. The Company represents and warrants that no person, other than the Holders of the Registrable Securities, has any right to require the Company to register any shares of the Company’s capital stock for sale or to include shares of the Company’s capital stock in any registration filed by the Company for the sale of shares of capital stock for its own account or for the account of any other person, other than the Existing Agreement, which is hereby terminated. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

7.2 Assignment; No Third Party Beneficiaries.

7.2.1This Agreement and the rights, duties, and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part.

7.2.2Prior to the expiration of the applicable Lock-Up Period to the Registrable Securities are subject, no Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee in accordance with the terms of this Agreement; provided however, that no assignment by any Holder shall be binding upon or obligate the Company unless and until the Company shall have received (i) prior written notice of such assignment and (ii) a joinder to this Agreement executed by the assignee, in a form reasonably acceptable to the Company.

To a Holder, to the address set forth below such Holder’s name on Exhibit A hereto.

7.4Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable.

7.5Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument.

7.6Entire Agreement. This Agreement (including all agreements entered into pursuant hereto and all certificates and instruments delivered pursuant hereto and thereto) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior and contemporaneous agreements, representations, understandings, negotiations, and discussions between the parties, whether oral or written, including, but not limited to, the Existing Agreement.

7.7Modifications and Amendments. No amendment, modification, or termination of this Agreement shall be binding upon the Company unless executed in writing by the Company. No amendment or modification of this Agreement shall be binding upon the Holders of the Registrable Securities unless executed in writing by the Holders of a majority of the Registrable Securities; provided, however, that (i) so long as the Initial Holders in the aggregate hold at least five percent of the outstanding shares of Common Stock of the Company, any amendment, modification or waiver under this Agreement shall require the prior written consent of the Sponsor and (ii) in the event any such amendment or modification would be adverse in any material respect to the material rights or obligations hereunder of a Holder of the Registrable Securities, the written consent of such Holder will also be required.

7.8Titles and Headings. Titles and headings of sections of this Agreement are for convenience only and shall not affect the construction of any provision of this Agreement.

7.9Waivers and Extensions. Any party to this Agreement may waive any right, breach, or default which such party has the right to waive; provided that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts.

7.10Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than those of the State of Delaware. Each party hereto hereby irrevocably consents to the exclusive jurisdiction of the courts of the State of Delaware and the United States District Court therein in connection with any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement.

7.11Waiver of Trial by Jury. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM, OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, OR THE ACTIONS OF THE HOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE, OR ENFORCEMENT HEREOF.

7.12Termination of Existing Agreement. The Existing Agreement is hereby terminated in its entirety and shall be null and void and of no further force or effect, without any action or notice on the part of the parties hereto.

7.13Term. This Agreement shall terminate upon the earlier of (i) the tenth anniversary of the date of this Agreement or (ii) the date as of which (A) all of the Registrable Securities have been sold pursuant to a Registration Statement (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174 thereunder (or any successor rule promulgated thereafter by the Commission)) or (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or the manner of sale. The provisions of Section 4.6 and Article V shall survive any termination.
