2.1 Long-Form Registrations.

(a) Subject to the terms of this Agreement, at any time after 180 days following the effective date of a Qualified IPO or the Company becoming Public (as a result of

the Merger or otherwise), the holders of at least a majority of the Series A Registrable Securities may request registration under the Securities Act of all or part of their then outstanding Registrable Securities represented by such Series A Registrable Securities on Form S-1 or any similar long-form registration; provided, that with respect to any demands under this clause (a) the anticipated aggregate offering price of the Registrable Securities covered by such registration exceeds $2,000,000 (net of underwriting discounts and commissions).

(b) Within ten (10) days after receipt of any written request pursuant to this Section 2.1, the Company will give written notice of such request to all other holders of Registrable Securities and will use its reasonable best efforts to include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion within 20 days after delivery of the Company’s notice, and, thereupon the Company will use its reasonable best efforts to file as soon as practicable, and in any event within 90 days of the receipt of such request, a registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration. All registrations requested pursuant to this Section 2.1 are referred to herein as “Long-Form Demand Registration.” The Company shall not be obligated to effect, or to take any action to effect, more than one (1) Long-Form Demand Registration pursuant to this Section 2.1. In addition, the Company shall not be obligated to effect, or to take any action to effect, any Long-Form Demand Registration during (i) the period starting with the date 90 days prior to the Company’s good faith estimate of the date of filing of, and ending on a date 90 days after the effective date of, a registration subject to Section 4 hereof; provided, that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; and (ii) the 180-day period following the Company being Public (as a result of the Merger or otherwise).

2.2 Short-Form Registrations. In addition to the Long-Form Demand Registration provided pursuant to Section 2.1 above, commencing the date on which the Company becomes eligible to register securities issued by it on a Form S-3 or any similar short-form registration, the holders of at least twenty-five percent (25%) of the Registrable Securities then outstanding will be entitled to request registrations under the Securities Act of all or part of their Registrable Securities on Form S-3, if available to the Company, or any similar short-form registration (“Short-Form Demand Registrations” and, together with the Long-Form Demand Registration, “Demand Registrations”); provided, however, that the anticipated aggregate offering amount of the Registrable Securities included in any such Short-Form Registration exceeds $1,000,000. Promptly after receipt of any request pursuant to this Section 2.2, the Company will give written notice of such request to all other holders of Registrable Securities and will use reasonable best efforts to include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion within 15 days after delivery of the Company’s notice. Once the Company has become subject to the reporting requirements of the Exchange Act, the Company will use its reasonable best efforts to make Short-Form Demand Registrations available for the sale of Registrable Securities. Demand Registrations will be Short-Form Demand Registrations whenever the Company is permitted to use any applicable short form. If a Short-Form Demand Registration is to be an underwritten Public Offering, and if the underwriters for marketing or other reasons request the inclusion in the registration statement of information which is not required under the Securities Act to be included in a registration statement on the applicable form for the Short-Form Demand Registration, the Company will provide such information as may be reasonably requested for

inclusion by the underwriters in the Short-Form Demand Registration. The Company shall not be obligated to effect more than two (2) Short-Form Demand Registrations in any twelve month period pursuant to this Section 2.2.

2.3 Payment of Expenses for Demand Registrations. The Company will pay all Registration Expenses (as defined in Section 7 below) for the Demand Registrations permitted under Sections 2.1 and 2.2 (other than underwriting discounts and commissions incurred by each holder of the Company’s securities participating in the registration). A registration will not count as a Demand Registration (i) unless a registration statement with respect thereto has become effective and remained effective in compliance with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement until the earlier of (x) such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement and (y) 120 days after the effective date of such registration statement, (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason not attributable to the selling holders and has not thereafter become effective, or (iii) if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such registration are not satisfied or waived, other than by reason of a failure on the part of the holders of the Registrable Securities to be registered thereunder.

2.4 Priority. If a Demand Registration is an underwritten Public Offering and the managing underwriters advise the Company in writing that in their opinion the inclusion of the number of Registrable Securities and other securities requested to be included exceeds the number of securities which can be sold in the offering without adversely affecting the marketability of such offering, then the managing underwriter may exclude securities (including Registrable Securities) from the registration and the underwriting and the number of securities that may be included in such registration and underwriting shall include first, the Series A Registrable Securities requested to be included in such registration, pro rata among the holders of such Series A Registrable Securities on the basis of the total number of Series A Registrable Securities owned by each such holder, second, the Registrable Securities (other than the Series A Registrable Securities) requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the total number of Registrable Securities owned by each such holder, and third, other equity securities requested to be included in such registration to be allocated pro rata among the holders of thereof on the basis of the number of such equity securities owned by each such holder. In no event will a Demand Registration pursuant to Section 2.1 count as a Long-Form Demand Registration for purposes of Section 2.1 unless at least thirty percent (30%) of all Registrable Securities requested to be registered in such Demand Registration by the initiating holders are, in fact, registered and sold in such registration.

2.5 Restrictions. Except as contemplated by Section 2.2 hereof, the Company will not be obligated to effect any Demand Registration within 180 days after the effective date of a previous Demand Registration. With respect to any Demand Registration, if (a) the Board of Directors of the Company reasonably and in good faith determines that such filing would be seriously detrimental to the Company or its stockholders, or require a disclosure of a material

fact that might reasonably be expected to have a material adverse effect on the Company or any plan or proposal by the Company or any of its subsidiaries to engage in any acquisition or disposition of assets or equity securities (other than in the ordinary course of business) or any merger, consolidation, tender offer, material financing or other significant transaction and (b) the Company shall furnish the holders of Registrable Securities who have requested a Demand Registration a certificate signed by an executive officer of the Company to such effect, the Company may postpone for up to 120 days the filing or the effectiveness of a registration statement for a Demand Registration; provided, that the Company may not postpone the filing or effectiveness of a registration statement for a Demand Registration for more than 120 days during any 12-month period.

2.6 Selection of Underwriters. The holders of a majority of the Registrable Securities initiating the Demand Registration shall have the right to select the investment banker(s) and manager(s) to administer the offering, subject to the Company’s approval which will not be unreasonably withheld or delayed.

3. Shelf Registration.

3.1 Right to Shelf Registration. Subject to the terms of this Agreement, at any time after 180 days following the effective date of a Qualified IPO or the Company becoming Public (as a result of the Merger or otherwise), the holders of at least a majority of the Series A Registrable Securities shall be entitled to request that the Company file a shelf registration statement with respect to all or part of their Registrable Securities represented by such Series A Registrable Securities pursuant to Rule 415 under the Securities Act (the “Shelf Registration”). The Company shall use its reasonable best efforts to have the Shelf Registration declared effective as soon as practicable after such filing, and shall use its reasonable best efforts to keep the Shelf Registration effective and updated, from the date such Shelf Registration is declared effective until the earliest to occur of (a) such time as the holder requesting the Shelf Registration has sold all of its Registrable Securities registered pursuant to the Shelf Registration, and (b) two (2) years from the date such Shelf Registration is declared effective (such period, the “Shelf Registration Effectiveness Period”). The Company shall not be obligated to effect, or to take any action to effect, more than one (1) Shelf Registration pursuant to this Section 3.1. In addition, the Company shall not be obligated to effect, or to take any action to effect, any Shelf Registration during (i) the period starting with the date 90 days prior to the Company’s good faith estimate of the date of filing of, and ending on a date 90 days after the effective date of, a registration subject to Section 4 hereof; provided, that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; and (ii) the 180-day period following the Company being Public (as a result of the Merger or otherwise).

3.2 Payment of Expenses for Shelf Registration. The Company will pay all Registration Expenses (as defined in Section 7 below) for the Shelf Registration permitted under Section 3.1 (other than underwriting discounts and commissions incurred by each holder of the Company’s securities participating in the registration). A registration will not count as a Shelf Registration (i) unless a registration statement with respect thereto has become effective and remained effective in compliance with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement until the earlier of (x) such time as all of such Registrable Securities have been disposed of in accordance with the

intended methods of disposition by the seller or sellers thereof set forth in such registration statement and (y) 90 days after the effective date of such registration statement, (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason not attributable to the selling holders and has not thereafter become effective, or (iii) if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such registration are not satisfied or waived, other than by reason of a failure on the part of the holders of the Registrable Securities to be registered thereunder.

3.3 Restrictions. With respect to any Shelf Registration, if (a) the Board of Directors of the Company reasonably and in good faith determines that such filing would be seriously detrimental to the Company or its stockholders, or require a disclosure of a material fact that might reasonably be expected to have a material adverse effect on the Company or any plan or proposal by the Company or any of its subsidiaries to engage in any acquisition or disposition of assets or equity securities (other than in the ordinary course of business) or any merger, consolidation, tender offer, material financing or other significant transaction and (b) the Company shall furnish the holders of Series A Registrable Securities who have requested a Shelf Registration a certificate signed by an executive officer of the Company to such effect, the Company may postpone for up to 120 days the filing or the effectiveness of a registration statement for a Shelf Registration; provided, that the Company may not postpone the filing or effectiveness of a registration statement for a Shelf Registration for more than 180 days during any 12-month period.

4. Piggyback Registration.

4.1 Right to Piggyback. At any time following a Qualified IPO or the Company becoming Public (as a result of the Merger or otherwise), whenever the Company proposes to register any of its equity securities (or securities that are convertible into equity securities) under the Securities Act for its own account or otherwise, and the registration form to be used may be used for the registration of any Registrable Securities (a “Piggyback Registration”) (except for the registrations on Form S-8 or Form S-4 or any successor form thereto), the Company will promptly give written notice to all holders of the Registrable Securities of its intention to effect such a registration and will use reasonable best efforts to include in such registration all Registrable Securities (in accordance with the priorities set forth in Sections 4.2 and 4.3 below) with respect to which the Company has received written requests for inclusion specifying the number of equity securities desired to be registered, which request shall be delivered within 20 days after the delivery of the Company’s notice; provided, that with respect to any Piggyback Registration, the holders of a majority of Registrable Securities shall have the right to waive and forego, as against themselves and all other holders of Registrable Securities, the right to include any Registrable Securities in such Piggyback Registration.

4.2 Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in the registration exceeds the number which can be sold in such offering without adversely affecting the marketability of such offering, then the managing underwriter may exclude securities (including Registrable Securities) from the registration and the underwriting,

and the number of securities that may be included in such registration and underwriting shall include first, any securities that the Company proposes to sell, second, the Series A Registrable Securities requested to be included in such registration, pro rata among the holders of such Series A Registrable Securities on the basis of the total number of Registrable Securities owned by each such holder, third, the Registrable Securities (other than the Series A Registrable Securities) requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the total number of Registrable Securities owned by each such holder, and fourth, other equity securities requested to be included in such registration to be allocated pro rata among the holders thereof on the basis of the number of such equity securities owned by each such holder.

4.3 Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in the registration exceeds the number which can be sold in such offering without adversely affecting the marketability of such offering, the Company will include in such registration first, the equity securities requested to be included therein by the holders requesting such registration and the Series A Registrable Securities requested to be included in such registration, pro rata among the holders of such equity securities and Series A Registrable Securities on the basis of the total number of equity securities and Series A Registrable Securities owned by each such holder, second, the Registrable Securities (other than the Series A Registrable Securities) requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the total number Registrable Securities owned by each such holder, and third, other equity securities requested to be included in such registration to be allocated pro rata among the holders thereof on the basis of the number of such equity securities owned by each such holder.

4.4 Other Registrations. If the Company has previously filed a registration statement with respect to Registrable Securities pursuant to this Section 4, and if such previous registration has not been withdrawn or abandoned, the Company will not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-8 or Form S-4 or any successor forms thereto), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least 180 days has elapsed from the effective date of such previous registration.

4.5 Selection of Underwriters. In connection with any Piggyback Registration, the Company will have such right to select the managing underwriters (subject to the approval of the holders of a majority of the Registrable Securities requested to be included in such registration, which approval shall not be unreasonably withheld or delayed).

5. Lock-Up Agreements.

5.1 Holders’ Agreements. To the extent not inconsistent with applicable law, each holder of Registrable Securities agrees that upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, it will (a) not sell, make any short sale of, loan, grant any option for the purchase of, otherwise dispose of, hedge or

transfer any of the economic interest in (or agree or commit to do any of the foregoing) any Registrable Securities (other than those included in the registration, if any) without the prior written consent of the Company or such underwriters, as the case may be, (i) for up to 14 days prior to, and during the 90-day period following, the effective date of a registration statement of the Company filed under the Securities Act; and (ii) for the 180-day period following the Company becoming Public (as a result of the Merger or otherwise); and (b) enter into and be bound by such form of agreement with respect to the foregoing as the Company or such managing underwriter may reasonably request; provided that each officer and director and each third party who holds 5.0% or more of the outstanding equity securities of the Company also agrees to such restrictions. Notwithstanding anything to the contrary contained in this Section 5.1, if (i) during the last 17 days of the initial lock-up period described above, the Company releases earnings results or announces material news or a material event or (ii) prior to the expiration of the initial lock-up period, the Company announces that it will release earnings results during the 15-day period following the last day of the initial lock-up period, then in each case the lock-up period described above will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless the managing underwriters waive, in writing, such extension. Nothing herein shall prevent a holder of Registrable Securities from transferring Registrable Securities to a permitted transferee as provided for in Section 7 of the Stockholders Agreement; provided, that any transferees of such Registrable Securities agrees to be bound by the provisions of this Agreement to the extent the transferor would be so bound.

5.2 Company’s Agreements. The Company agrees not to effect, and, to the extent not inconsistent with applicable laws, to cause each holder of its equity securities purchased from the Company at any time after the date of this Agreement (except in a registered public offering) not to effect, any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, (i) during the 90-day period following, the effective date of a registration statement of the Company filed under the Securities Act; or (ii) during the 180-day period following the Company becoming Public (as a result of the Merger or otherwise)(in each case except as part of any such underwritten registration or pursuant to registrations on Form S-8 or Form S-4 or any successor forms thereto), unless the underwriters managing the Public Offering otherwise agree.

6. Registration Procedures. Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement, the Company will use its reasonable best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company will as expeditiously as possible:

(a) prepare and, as soon as practicable after the end of the period within which requests for registration may be given to the Company, file with the Commission a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become effective (provided that before filing a registration statement or prospectus, or any amendments or supplements thereto, the Company will furnish copies of all such documents proposed to be filed to one counsel designated by holders of a majority of the Registrable Securities covered by such registration statement);

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus(es) used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 120 days, and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

(c) furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the prospectus(es) included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(d) use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as Investor reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph, (ii) consent to general service of process in any such jurisdiction, or (iii) subject it to taxation in any such jurisdiction);

(e) promptly notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and, at the request of any such seller, the Company will prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made;

(f) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed or if no such securities are then listed, such securities exchange as the holders of a majority of the Registrable Securities included in such registration may request;

(g) provide a transfer agent, registrar and CUSIP number for all such Registrable Securities not later than the effective date of such registration statement;

(h) enter into such customary agreements (including underwriting agreements in customary form) and take all such other customary actions as the holders of a majority of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities;

(i) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; provided, however, that any records, information or documents that are furnished by the Company and that are non-public shall be used only in connection with such registration and shall be kept strictly confidential by any seller of Registrable Securities except to the extent disclosure of such records, information or documents is required by written order of a court or other governmental authority having jurisdiction;

(j) advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for such purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

(k) at least 48 hours prior to the filing of any registration statement or prospectus, or any amendment or supplement to such registration statement or prospectus, furnish a copy thereof to each seller of such Registrable Securities and refrain from filing any such registration statement, prospectus, amendment or supplement to which counsel selected by the holders of a majority of the Registrable Securities being registered shall have reasonably objected on the grounds that such document does not comply in all material respects with the requirements of the Securities Act or the rules and regulations thereunder, unless, in the case of an amendment or supplement, in the opinion of counsel for the Company the filing of such amendment or supplement is reasonably necessary to protect the Company from any liabilities under any applicable federal or state law and such filing will not violate applicable laws;

(l) at the request of any seller of such Registrable Securities in connection with an underwritten offering, furnish on the date or dates provided for in the underwriting agreement: (i) an opinion of counsel, addressed to the underwriters and the sellers of Registrable Securities, covering such matters as such counsel, underwriters and the sellers may reasonably agree upon, including such matters as are customarily furnished in connection with an underwritten offering, and (ii) a letter or letters from the independent certified public accountants of the Company addressed to the underwriters and the sellers of Registrable Securities, covering such matters as such accountants, underwriters and sellers may reasonably agree upon, in which letter(s) such accountants shall state, without limiting the generality of the foregoing, that they are independent certified public accountants within the meaning of the Securities Act and that in their opinion the financial statements and other financial data of the Company included in the registration statement, the prospectus(es), or any amendment or supplement thereto, comply in all material respects with the applicable accounting requirements of the Securities Act; and

(m) make senior executives of the Company reasonably available to assist the underwriters with respect to, and accompany the underwriters on, the so-called “road show” in connection with the marketing efforts for, and the distribution and sale of Registrable Securities pursuant to a registration statement.

To the extent that any expenses incident to any registration are not required to be paid by the Company, each holder of Registrable Securities included in a registration will pay all such expenses which are clearly and solely attributable to the registration of such holder’s Registrable Securities so included in such registration, and any other expenses not so attributable to one holder will be borne and paid by all sellers of securities included in such registration in proportion to the number of securities so included by each such seller.

8. Indemnification.

8.1 By the Company. The Company agrees to indemnify, to the extent permitted by law, each holder of Registrable Securities, its members, managers, officers, employees and directors and each Person who controls such holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including, but not limited to, attorneys’ fees and expenses) caused by any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus, or

any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such holder expressly for use therein or by such holder’s failure to deliver a copy of the prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities. The payments required by this Section 8.1 will be made periodically during the course of the investigation or defense, as and when bills are received or expenses incurred. Notwithstanding anything to the contrary contained herein, the indemnity agreement contained in this Section 8.1 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable to any holder of Registrable Securities, underwriter or controlling Person for any such loss, claim, damage, liability, expenses or action to the extent that it arises out of or is based upon an untrue statement or omission that is contained in or omitted from any information so furnished in writing by such holder, underwriter or controlling Person for the acknowledged purpose of inclusion in such registration statement, prospectus or preliminary prospectus.

8.2 By Each Holder of Registrable Securities. In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will furnish to the Company in writing such information as is reasonably necessary for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify the Company, its members, managers, directors, employees and officers and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus, or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in or omitted from any information so furnished in writing by such holder for the acknowledged purpose of inclusion in such registration statement, prospectus or preliminary prospectus; provided that the obligation to indemnify will be several, not joint and several, among such holders of Registrable Securities and the liability of each such holder of Registrable Securities will be in proportion to and limited in all events to the gross proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement, except in the case of willful fraud. Notwithstanding anything to the contrary contained herein, the indemnity agreement contained in this Section 8.2 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld).

8.3 Procedure. Each party entitled to indemnification under this Section 8 (the “Indemnified Party”) shall give written notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has received written notice of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to

assume the defense of any such claim or any litigation resulting therefrom, provided such counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld or delayed). The Indemnified Party may participate in such defense at such Indemnified Party’s expense; provided, however, that the Indemnifying Party shall bear the expense of such defense of the Indemnified Party if (i) the Indemnifying Party has agreed in writing to pay such expenses, (ii) the Indemnifying Party shall have failed to assume the defense of such claim or employ counsel reasonably satisfactory to the Indemnified Party, or (iii) in the reasonable judgment of the Indemnified Party, based upon the written advice of such Indemnified Party’s counsel, representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest; provided, however, that in no event shall the Indemnifying Party be liable for the fees and expenses of more than one counsel (excluding one local counsel per jurisdiction as necessary) for all Indemnified Parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same event, allegations or circumstances. The Indemnified Party shall not make any settlement without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The failure of any Indemnified Party to give notice as provided herein shall relieve the Indemnifying Party of its obligations under this Section 8 only to the extent that such failure to give notice shall materially adversely prejudice the Indemnifying Party in the defense of any such claim or any such litigation. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the prior written consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement (A) which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation in form and substance reasonably satisfactory to such Indemnified Party or (B) which includes an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Party.

8.4 Survival. The indemnification provided for under this Agreement will 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 will survive the transfer of securities.

9. Contribution.

9.1 Contribution. If the indemnification provided for in Section 8 from the Indemnifying Party is unavailable to or unenforceable by the Indemnified Party in respect to any costs, fines, penalties, losses, claims, damages, liabilities or expenses referred to herein, then the 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 costs, fines, penalties, losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Parties 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 or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Parties, and the parties’ relative intent, knowledge, access to

information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the costs, fines, penalties, losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8, any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. For the avoidance of doubt and notwithstanding anything to the contrary contained herein, in no event shall any contribution by a holder of Registrable Securities under this Section 9.1 exceed the gross proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement, except in the case of willful fraud.

9.2 Equitable Considerations; Etc. The Company and the holders of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation which 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) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

10. Compliance with Rule 144 and Rule 144A. In the event that the Company (a) registers a class of securities under Section 12 of the Exchange Act, (b) issues an offering circular meeting the requirements of Regulation A under the Securities Act or (c) commences to file reports under Section 13 or 15(d) of the Exchange Act, then at the request of any holder of Registrable Securities who proposes to sell securities in compliance with Rule 144 of the Securities Act, the Company will (i) forthwith furnish to such holder a written statement of compliance with the filing requirements of the Commission as set forth in Rule 144, as such rule may be amended from time to time and (ii) make available to the public and such holders such information, and take such action as is reasonably necessary, to enable the holders of Registrable Securities to make sales pursuant to Rule 144. Unless the Company is subject to Section 13 or 15(d) of the Exchange Act, the Company will provide to the holder of Registrable Securities and to any prospective purchaser of Registrable Securities under Rule 144A of the Commission, the information described in Rule 144A(d)(4) of the Commission.

11. Participation in Underwritten Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (a) agrees to sell its securities on the basis provided in any underwriting arrangements approved by such Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

12. Delay of Registration. No holder of Registrable Securities shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration as a result of any controversy that might arise with respect to the interpretation or implementation of this Agreement.

13. Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Agreement may be assigned (but only with all related obligations) by a holder of Registrable Securities to a transferee or assignee (a) that is a subsidiary, parent, partner, limited partner, retired partner, member, retired member or

stockholder of a holder of Registrable Securities, (b) that is an affiliated fund or entity of the holder of Registrable Securities, which means with respect to a limited liability company or a limited liability partnership, a fund or entity managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by, or under common control with such manager or managing member or general partner or management company (such a fund or entity, an “Affiliated Fund”), (c) who is an Immediate Family Member of a holder of Registrable Securities, or (d) that is a trust for the benefit of an individual holder of Registrable Securities or such holder’s Immediate Family Member, provided the Company is, within a reasonable time after such transfer, furnished with a written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if the transferee agrees to be bound by this Agreement and immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act.

14. Termination of Registration Rights. No holder of Registrable Securities shall be entitled to exercise any registration rights provided in this Agreement after the earlier of (a) five (5) years following the consummation of a Qualified IPO or the Company becoming Public (as a result of the Merger or otherwise), or (b) such time as Rule 144 or another similar exemption under the Securities Act is available for the sale of all of such holder’s shares of the Company’s equity securities during a three-month period without registration.

15. Miscellaneous.

15.1 Limitations on Subsequent Registration Rights. The Company has not entered, and will not hereafter enter, into any agreement with respect to its securities which grants any superior or more favorable rights or terms to any Person than those provided to the holders of Registrable Securities in this Agreement.

15.2 Adjustments Affecting Registrable Securities. The Company will not take any action, or permit any change to occur, with respect to its Certificate of Incorporation, Bylaws, or other governing documents, as appropriate, which could reasonably be expected to adversely affect the ability of the holders of Registrable Securities to include such Registrable Securities in a registration undertaken pursuant to this Agreement or which would reasonably be expected to adversely affect the marketability of such Registrable Securities in any such registration.

15.3 Amendments and Waivers. Except as otherwise expressly provided herein, the provisions of this Agreement may be amended or waived at any time only by the written agreement of the Company and the holders of at least a majority of the Registrable Securities; provided, however, that the provisions of this Agreement may not be amended or waived without the consent of the holders of all the Registrable Securities adversely affected by such amendment or waiver if such amendment or waiver adversely affects a portion of the Registrable Securities but does not so adversely affect all of the Registrable Securities. Any waiver, permit, consent or approval of any kind or character on the part of any such holders of any provision or condition of this Agreement must be made in writing and shall be effective only to the extent specifically set forth in writing. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of Registrable Securities and the Company.

15.4 Successors and Assigns. Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto will bind and inure to the benefit of the respective successors and assigns of the parties hereto, whether so expressed or not. In addition, and whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of holders of Registrable Securities are also for the benefit of, and enforceable by, any permitted transferee or assignee of such Registrable Securities as provided for in Section 13 hereof and Section 7 of the Stockholders Agreement.

15.5 Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience of reference only and do not constitute a part of and shall not be utilized in interpreting this Agreement.

15.6 Notices. Any notices required or permitted to be sent hereunder shall be delivered personally, via facsimile transmission (with confirmation), or mailed, via certified mail (return receipt requested), or delivered by overnight courier service to the following addresses, or such other address as any party hereto designates by written notice to the Company, and shall be deemed to have been given upon delivery, if delivered personally or via facsimile, three (3) Business Days after mailing, if mailed, or one (1) Business Day after delivery to the courier, if delivered by overnight courier service:

Any award or decision obtained from any such arbitration proceeding shall be final and binding on the parties, and judgment upon any award thus obtained may be entered in any court having jurisdiction thereof. No action at law or in equity based upon any claim arising out of or related to this Agreement shall be instituted in any court by any Stockholder except (i) an action to compel arbitration pursuant to this Section 15.8 or (ii) an action to enforce an award obtained in an arbitration proceeding in accordance with this Section 15.8, in which case, the provisions of Sections 15.9 and 15.10 shall apply. For the avoidance of doubt, the provisions of Sections 15.9 and 15.10 shall be subordinate to and shall only apply in connection with an action at law or in equity based upon clauses (i) and/or (ii) of the immediately preceding sentence of this Section 15.8.

15.9 CONSENT TO JURISDICTION. EACH PARTY HERETO HEREBY IRREVOCABLY AGREES THAT ANY SUIT, ACTION, PROCEEDING OR CLAIM AGAINST IT ARISING OUT OF OR IN ANY WAY RELATING TO THIS AGREEMENT OR ANY OF THE RELATED AGREEMENTS, OR ANY JUDGMENT ENTERED BY ANY COURT IN RESPECT THEREOF, MAY BE BROUGHT OR ENFORCED IN THE STATE OR FEDERAL COURTS LOCATED IN SAN FRANCISCO, CALIFORNIA, AND EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY PROCEEDING BROUGHT IN SAN FRANCISCO, CALIFORNIA AND FURTHER IRREVOCABLY WAIVES ANY CLAIMS THAT ANY SUCH PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

15.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHT, POWER, OR REMEDY UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE RELATED AGREEMENTS OR UNDER OR IN CONNECTION WITH ANY AMENDMENT, INSTRUMENT, DOCUMENT, OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY RELATIONSHIP EXISTING IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED AGREEMENT, AND AGREE THAT ANY SUCH ACTION SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. THE TERMS AND PROVISIONS OF THIS SECTION CONSTITUTE A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING INTO THIS AGREEMENT.

15.11 Reproduction of Documents. This Agreement and all documents relating hereto, including, but not limited to, (i) consents, waivers, amendments and modifications which may hereafter be executed, and (ii) certificates and other information previously or hereafter furnished, may be reproduced by any photographic, photostatic, microfilm, optical disk, micro-card, miniature photographic or other similar process. The parties agree that any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding, whether or not the original is in existence and whether or not such reproduction was made by a party in the regular course of business, and that any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence.

15.12 Remedies. Each of the parties to this Agreement will be entitled to enforce its rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party shall be entitled to immediate injunctive relief or specific performance without bond or the necessity of showing actual monetary damages in order to enforce or prevent any violations of the provisions of this Agreement.

15.13 Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

15.14 Entire Agreement. This Agreement, together with all other agreements entered into by the parties hereto in connection therewith, constitutes the complete and final agreement of the parties concerning the matters referred to herein, and supersedes all prior agreements and understandings, including, without limitation, the Original Registration Rights Agreement.

15.15 Trustee Exculpation. For avoidance of doubt, when this Agreement is executed by a trustee of a trust, such execution is by the trustee, not individually, but solely as trustee in the exercise of and under the power and authority conferred upon and invested in such trustee, and it is expressly understood and agreed that nothing contained in this Agreement shall be construed as imposing any liability on any such trustee personally to pay any amounts required to be paid hereunder or thereunder, or to perform any covenant, either express or implied, contained herein or therein, all such personal liability, if any, has been expressly waived by the parties by their execution hereof. Any liability of a trust shall not be a personal liability of any trustee, grantor or beneficiary thereof, and any recourse against a trustee shall be solely against the assets of the pertinent trust.

15.16 Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute one instrument.
