NOW, THEREFORE, in consideration of the mutual covenants and agreements contained in this Agreement, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

ARTICLE I

RESALE SHELF REGISTRATION

Section 1.1 Resale Shelf Registration Statement. Subject to the other applicable provisions of this Agreement, the Company shall use its reasonable best efforts to prepare and file within 120 days after the date hereof, a registration statement covering the sale or distribution from time to time by the Holders, on a delayed or continuous basis pursuant to Rule 415 of the Securities Act, of all of the Registrable Securities on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, then such registration shall be on another appropriate form and shall provide for the registration of such Registrable Securities for resale by the Holders in accordance with any reasonable method of distribution elected by the Purchasers) (the “Resale Shelf Registration Statement”), and if the Company is a WKSI as of the filing date, the Resale Shelf Registration Statement shall consist of an Automatic Shelf Registration Statement, or a prospectus supplement to an effective Automatic Shelf Registration Statement, that shall become effective upon filing with the SEC pursuant to Rule 462(e). If the Resale Shelf Registration Statement is not an Automatic Shelf Registration Statement, then the Company shall use its reasonable best efforts to cause such Resale Shelf Registration Statement to be declared effective by the SEC as promptly as is reasonably practicable after the filing thereof.

1

Section 1.2 Effectiveness Period. Once declared effective, the Company shall, subject to the other applicable provisions of this Agreement, use its reasonable best efforts to cause the Resale Shelf Registration Statement to be continuously effective and usable until such time as there are no longer any Registrable Securities (the “Effectiveness Period”).

Section 1.3 Subsequent Shelf Registration Statement. If any Shelf Registration Statement ceases to be effective under the Securities Act for any reason at any time during the Effectiveness Period, the Company shall use its reasonable best efforts to as promptly as is reasonably practicable cause such Shelf Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its reasonable best 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 (a “Subsequent Shelf Registration Statement”) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by the Holders thereof of all securities that are Registrable Securities as of the time of such filing. If a Subsequent Shelf Registration Statement is filed, the Company shall use its reasonable best efforts to (a) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that if the Company is a WKSI as of the filing date, the Subsequent Shelf Registration Statement shall be an Automatic Shelf Registration Statement, or a prospectus supplement to an effective Automatic Shelf Registration Statement, that shall become effective upon filing with the SEC pursuant to Rule 462(e)) and (b) keep such Subsequent Shelf Registration Statement continuously effective and usable until the end of the Effectiveness Period. Any such Subsequent Shelf Registration Statement shall be a registration statement on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration Statement shall be on another appropriate form and shall provide for the registration of such Registrable Securities for resale by the Holders in accordance with any reasonable method of distribution elected by the Purchasers.

Section 1.4 Supplements and Amendments. The Company shall supplement and amend any Shelf Registration Statement if required by the Securities Act or the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement.

Section 1.5 Subsequent Holder Notice. If a Person entitled to the benefits of this Agreement becomes a Holder after a Shelf Registration Statement becomes effective under the Securities Act, the Company shall, as promptly as is reasonably practicable following delivery of written notice to the Company of such Person becoming a Holder and requesting for its name to be included as a selling securityholder in the prospectus related to the Shelf Registration Statement (a “Subsequent Holder Notice”):

2

(a) if required and permitted by applicable law, file with the SEC a supplement to the related prospectus or a post-effective amendment to the Shelf Registration Statement so that such Holder is named as a selling securityholder in the Shelf Registration Statement and the related prospectus in such a manner as to permit such Holder to deliver a prospectus to purchasers of the Registrable Securities in accordance with applicable law; provided, however, that the Company shall not be required to file more than one post-effective amendment or a supplement to the related prospectus for such purpose in any 30-day period;

(b) if, pursuant to Section 1.5(a), the Company shall have filed a post-effective amendment to the Shelf Registration Statement that is not automatically effective, use its reasonable best efforts to cause such post-effective amendment to become effective under the Securities Act as promptly as is reasonably practicable; and

(c) notify such Holder as promptly as is reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 1.5(a).

Section 1.6 Underwritten Offering.

(a) Subject to any applicable restrictions on transfer in the Stockholders Agreement or otherwise, one or more Holders of Registrable Securities may, after the Resale Shelf Registration Statement becomes effective, deliver a written notice to the Company (the “Underwritten Offering Notice”) specifying that the sale of some or all of the Registrable Securities subject to such Resale Shelf Registration Statement, is intended to be conducted through an underwritten offering or an underwritten block trade or bought deal; provided, however, that the Holders may not, without the Company’s prior written consent, (i) launch an underwritten offering or underwritten block trade or bought deal the anticipated gross proceeds of which shall be less than $25,000,000 (unless the Holder, collectively with all of its Affiliates, is proposing to sell all of their remaining Registrable Securities), (ii) launch more than three underwritten offerings or underwritten block trades or bought deals at the request of the Holders within any 365-day period or (iii) launch an underwritten offering or underwritten block trade or bought deal within the period (a “Quarterly Blackout Period”) commencing on the seventh calendar day of the third month of each fiscal quarter and ending at the start of the second full trading day following the date of public disclosure of the financial results for that fiscal quarter (such qualifying underwritten offering or underwritten block trade or bought deal, an “Underwritten Offering”).

(b) In the event of an Underwritten Offering, the Holder(s) delivering the Underwritten Offering Notice shall select the managing underwriter(s) to administer the Underwritten Offering; provided that the choice of such managing underwriter(s) shall be subject to the consent of the Company, which shall not be unreasonably withheld. In making the determination to consent to the Holder or Holders’, as applicable, choice of managing underwriter(s), the Company may take into account its business and strategic interests. The Company and the Holders participating in an Underwritten Offering will enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such offering.

3

(c) Upon receipt of an Underwritten Offering Notice (which, in the case of an Underwritten Offering that is an underwritten block trade or bought deal, shall be received by the Company not less than two Business Days prior to the day such offering is first anticipated to commence), the Company shall promptly deliver to each other Holder written notice thereof and if, within three Business Days after the date of the delivery of such notice (or one Business Day in the case of an Underwritten Offering that is an underwritten block trade or bought deal), a Holder shall so request in writing, the Company shall as expeditiously as possible use its reasonable best efforts to facilitate such Underwritten Offering (which, in the case of an Underwritten Offering that is an underwritten block trade or bought deal, close as early as two Business Days after the date it commences) include in such Underwritten Offering all or any part of such Holder’s Registrable Securities as such Holder requests to be registered, subject to Section 1.6(d).

(d) The Company will not include in any Underwritten Offering pursuant to this Section 1.6 any securities that are not Registrable Securities (other than the WPP Securities) without the prior written consent of the Holder(s) participating in such Underwritten Offering. If the managing underwriter or underwriters advise the Company and such Holder(s) in writing that in its or their good faith opinion the number of Registrable Securities (and, if permitted hereunder, other securities requested to be included in such offering) exceeds the number of securities which can be sold in such offering in light of market conditions or is such so as to adversely affect the success of such offering, the Company will include in such offering only such number of securities that can be sold without adversely affecting the marketability of the offering, which securities will be so included in the following order of priority: (i) first, the Registrable Securities of the Holders that have requested to participate in such Underwritten Offering, allocated pro rata among such Holders on the basis of their respective then-owned Registrable Securities, and (ii) second, any other securities of the Company that have been requested to be so included (including any WPP Securities, to the extent applicable).

Section 1.7 Take-Down Notice. Subject to the other applicable provisions of this Agreement, including the limitations and requirements in Section 1.6 regarding Underwritten Offerings, at any time that any Shelf Registration Statement is effective, if a Holder delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to effect a sale or distribution of all or part of its Registrable Securities included by it on any Shelf Registration Statement (a “Shelf Offering”) and stating the number of the Registrable Securities to be included in such Shelf Offering, then the Company shall amend, subject to the other applicable provisions of this Agreement, or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be sold and distributed pursuant to the Shelf Offering.

Section 1.8 Piggyback Registration.

(a) If the Company proposes to file a registration statement under the Securities Act with respect to an offering of Common Stock or securities convertible into, or exchangeable or exercisable for, Common Stock, whether or not for sale for its own account (other than a registration statement (i) on Form S-4, Form S-8 or any successor forms thereto or (ii) filed to effectuate an exchange offer or any employee benefit or dividend reinvestment plan), then the Company shall give prompt written notice of such filing, which notice shall be given, to the extent reasonably practicable, no later than seven Business Days prior to the filing date (the “Piggyback Notice”) to the Holders. The Piggyback Notice shall offer such Holders the opportunity to include (or cause to be included) in such registration statement the number of shares of Registrable Securities as each such Holder may request (each, a “Piggyback Registration Statement”). Subject to Section 1.8(b), the Company shall include in each Piggyback Registration Statement all

4

Registrable Securities with respect to which the Company has received written requests for inclusion therein (each, a “Piggyback Request”) within five Business Days after the date of the Piggyback Notice but in any event not later than two Business Day prior to the filing date of a Piggyback Registration Statement. The Company shall not be required to maintain the effectiveness of a Piggyback Registration Statement beyond the earlier of (x) 180 days after the effective date thereof and (y) consummation of the distribution by the Holders of the Registrable Securities included in such registration statement. The Company may postpone or withdraw a Piggyback Registration Statement at any time prior to effectiveness of such Piggyback Registration Statement without incurring any liability to the Holders.

(b) Subject to any applicable restrictions on transfer in the Stockholders Agreement, if any of the securities to be registered pursuant to the registration giving rise to the rights under this Section 1.8 are to be sold in an underwritten offering, the Company shall use reasonable best efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit Holders who have timely submitted a Piggyback Request in connection with such offering to include in such offering all Registrable Securities included in each Holder’s Piggyback Request on the same terms and subject to the same conditions as any other shares of capital stock, if any, of the Company included in the offering. Notwithstanding the foregoing, if the managing underwriter or underwriters of such underwritten offering advise the Company in writing that in its or their good faith opinion the number of securities exceeds the number of securities which can be sold in such offering in light of market conditions or is such so as to adversely affect the success of such offering, the Company will include in such offering only such number of securities that can be sold without adversely affecting the marketability of the offering, which securities will be so included in the following order of priority: (i) first, the securities proposed to be sold by the Company for its own account; (ii) second, the Registrable Securities of the Holders that have requested to participate in such underwritten offering and any other persons with piggyback registration rights who have the right to participate and that have requested to participate in such offering, allocated pro rata among such selling holders on the basis of their respective then-owned registrable securities; and (iii) third, any other securities of the Company that have been requested to be included in such offering, allocated pro rata among such holders on the basis of the percentage of securities then held by such holders; provided that Holders may, prior to the earlier of (a) the effectiveness of the registration statement and (b) the time at which the offering price or underwriter’s discount is determined with the managing underwriter or underwriters, withdraw their request to be included in such registration pursuant to this Section 1.8.

The Holders agree that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.1(f), Section 2.1(o)(ii) or Section 2.1(o)(iii), the Holders shall discontinue disposition of any Registrable Securities covered by such registration statement or the related prospectus until receipt of the copies of the supplemented or amended prospectus, which supplement or amendment shall, subject to the other applicable provisions of this Agreement, be prepared and furnished as soon as reasonably practicable, or until the Holders are advised in writing by the Company that the use of the applicable prospectus may be resumed, and have received copies of any amended or supplemented prospectus or any additional or supplemental filings which are incorporated, or deemed to be incorporated, by reference in such prospectus (such period during which disposition is discontinued being an “Interruption Period”) and, if requested by the Company, the Holders shall use reasonable best efforts to return, and cause the Holders to return, to the Company all copies then in their possession, of the prospectus covering such Registrable Securities at the time of receipt of such request. As soon as practicable after the Company has determined that the use of the applicable prospectus may be resumed, the Company will notify the Holders thereof. In the event the Company invokes an Interruption Period hereunder and in the sole discretion of the Company the need for the Company to continue the Interruption Period ceases for any reason, the Company shall, as soon as reasonably practicable, provide written notice to the Holders that such Interruption Period is no longer applicable.

Section 2.2 Suspension. The Company shall be entitled, on two occasions during any 12-month period, for a period of time not to exceed an aggregate of 75 days during any 12-month period (any such period a “Suspension Period”), to (x) postpone or defer any registration of Registrable Securities and shall have the right not to file and not to cause the effectiveness of any registration covering any Registrable Securities, (y) suspend the use of any prospectus and registration statement covering any Registrable Securities and (z) require the Holders to suspend any offerings or sales of Registrable Securities pursuant to a registration statement, if the Company delivers to the Holders a certificate signed by an executive officer certifying that such registration and offering would (i) require the Company to make an Adverse Disclosure or (ii) materially interfere with any bona fide material financing, acquisition, disposition or other similar transaction involving the Company or any of its subsidiaries then under consideration. Such certificate shall contain a statement of the reasons for such suspension and an approximation of the anticipated length of such suspension. The Holders shall keep the information contained in such certificate confidential subject to the same terms set forth in Section 2.1(m). If the Company defers any registration of Registrable Securities in response to an Underwritten Offering Notice or requires the Holder(s) to suspend any Underwritten Offering, such Holder(s) shall be entitled to withdraw such Underwritten Offering Notice and if it does so, such request shall not be treated for any purpose as the delivery of an Underwritten Offering Notice pursuant to Section 1.6.

ARTICLE III

INDEMNIFICATION

Section 3.1 Indemnification by Company. To the extent permitted by applicable law, the Company will, with respect to any Registrable Securities covered by a registration statement or prospectus, or as to which registration, qualification or compliance under applicable “blue sky” laws has been effected pursuant to this Agreement, indemnify and hold harmless each Holder, each Holder’s current and former officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and employees, and each Person controlling such Holder within the meaning of Section 15 of the Securities Act and such Holder’s current and former officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and employees, and each underwriter thereof, if any, and each Person who controls any such underwriter within the meaning of Section 15 of the Securities Act (collectively, the “Company Indemnified Parties”), from and against any and all expenses, claims, losses, damages, costs (including costs of preparation and reasonable and documented attorney’s fees and any legal or other documented fees or expenses actually incurred by such party in connection with any investigation or proceeding), judgments, fines, penalties, charges, amounts paid in settlement and other liabilities, joint or several, (or actions in respect thereof) (collectively, “Losses”) to the extent arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular, “issuer free writing prospectus” (as such term is defined in Rule 433 under the Securities Act) or other document, in each case related to such registration statement, or any amendment or supplement thereto, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rules or regulations thereunder applicable to the Company in connection with any registration or offering hereunder and (without limiting the preceding portions of this Section 3.1), the Company will reimburse each of the Company Indemnified Parties for any reasonable and documented out-of-pocket legal expenses

12

and any other reasonable and documented out-of-pocket expenses actually incurred in connection with investigating, defending or, subject to the last sentence of this Section 3.1, settling any such Losses or action, as such expenses are incurred; provided that the Company’s indemnification obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable to a Holder in any such case for any such Losses or action to the extent that it arises out of or is based upon a violation or alleged violation of any state or federal law (including any claim arising out of or based on any untrue statement or alleged untrue statement or omission or alleged omission in the registration statement or prospectus) which occurs in reliance upon and in conformity with written information regarding such Holder furnished to the Company by such Holder or its authorized representatives expressly for use in connection with such registration by or on behalf of any Holder.

Section 3.2 Indemnification by Holders. To the extent permitted by applicable law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which registration or qualification or compliance under applicable “blue sky” laws is being effected, indemnify, severally and not jointly with any other Holders, the Company, each of its representatives and Affiliates and each underwriter thereof, and each Person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act (collectively, the “Holder Indemnified Parties”), against all Losses (or actions in respect thereof) to the extent arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular, “issuer free writing prospectus” or other document, in each case related to such registration statement, or any amendment or supplement thereto, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or and will reimburse each of the Holder Indemnified Parties for any reasonable and documented out-of-pocket legal expenses and any other reasonable and documented out-of-pocket expenses actually incurred in connection with investigating, defending or, subject to the last sentence of this Section 3.2, settling any such Losses or action, as such expenses are incurred, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular, “issuer free writing prospectus” or other document in reliance upon and in conformity with written information regarding such Holder furnished to the Company by such Holder or its authorized representatives and stated to be specifically for use therein; provided, however, that in no event shall any indemnity under this Section 3.2 payable by any of the Purchasers and any Holder exceed an amount equal to the net proceeds (after deducting Selling Expenses) actually received by such Holder in respect of the Registrable Securities sold pursuant to the registration statement. The indemnity agreement contained in this Section 3.2 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the prior written consent of the applicable Holder (which consent shall not be unreasonably withheld or delayed).

13

Section 3.3 Notification. If any Person shall be entitled to indemnification under this Article III (each, an “Indemnified Party”), such Indemnified Party shall give prompt notice to the party required to provide indemnification (each, an “Indemnifying Party”) of any claim or of the commencement of any proceeding as to which indemnity is sought. The Indemnifying Party shall have the right, exercisable by giving written notice to the Indemnified Party as promptly as reasonably practicable after the receipt of written notice from such Indemnified Party of such claim or proceeding, to, unless in the Indemnified Party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, assume, at the Indemnifying Party’s expense, the defense of any such claim or litigation, with counsel reasonably satisfactory to the Indemnified Party and, after notice from the Indemnifying Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such Indemnified Party hereunder for any legal expenses and other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however, that an Indemnified Party shall have the right to employ separate counsel in any such claim or litigation, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless the Indemnifying Party (i) agrees to pay such fees and expenses or (ii) shall have failed within a reasonable period of time to assume, or in the event of a conflict of interest cannot assume, such defense or shall have failed to employ counsel reasonably satisfactory to such Indemnified Party. The failure of any Indemnified Party to give notice as provided herein shall relieve an Indemnifying Party of its obligations under this Article III only to the extent that the failure to give such notice is materially prejudicial or harmful to such Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the prior written consent of each Indemnified Party (which consent shall not be unreasonably withheld or delayed), consent to entry of any judgment or enter into any settlement which does not (x) include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release, in form and substance reasonably satisfactory to the Indemnified Party, from all liability in respect to such claim or litigation or (y) involve the imposition of equitable remedies or the imposition of any obligations on the Indemnified Party or adversely affects such Indemnified Party other than as a result of financial obligations for which such Indemnified Party would be entitled to indemnification hereunder. The indemnity agreements contained in this Article III shall not apply to amounts paid in settlement of any claim, loss, damage, liability or action if such settlement is effected without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The indemnification set forth in this Article III shall be in addition to any other indemnification rights or agreements that an Indemnified Party may have. An Indemnifying Party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel (together with one local counsel, if appropriate) for all parties indemnified by such Indemnifying Party with respect to such claim, unless in the reasonable judgment of any Indemnified Party a conflict of interest may exist between such Indemnified Party and any other Indemnified Parties with respect to such claim.

Section 3.4 Contribution. If the indemnification provided for in this Article III is held by a court of competent jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any Losses or action referred to therein, then, subject to the limitations contained in this Article III, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses or action in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the actions, statements or omissions that resulted in such Losses or action, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, shall be determined by reference to, among other

14

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 (or omitted) by, or relates to information supplied by such Indemnifying Party or such Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action, statement or omission. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 3.4 was determined solely upon 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 sentence of this Section 3.4. Notwithstanding the foregoing, the amount any Purchaser or any Holder will be obligated to contribute pursuant to this Section 3.4 will be limited to an amount equal to the net proceeds received by such Purchaser or Holder in respect of the Registrable Securities sold pursuant to the registration statement which gives rise to such obligation to contribute. 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.

ARTICLE IV

TRANSFER AND TERMINATION OF REGISTRATION RIGHTS

Section 4.1 Transfer of Registration Rights. Any rights to cause the Company to register securities granted to a Holder under this Agreement may be transferred or assigned to any Person in connection with a Transfer (as defined in the Stockholders Agreement) of Series B Preferred Stock or Common Stock, as applicable, (i) permitted under Section 3.1(d) of the Stockholders Agreement or (ii) permitted under Section 3.1(a) of the Stockholders Agreement and, in the case of this clause (ii), representing 5% or more of the outstanding Common Stock on an as-converted basis; provided, however, that (x) prior written notice of such assignment of rights is given to the Company and (y) such transferee agrees in writing to be bound by, and subject to, this Agreement as a “Holder” pursuant to a written instrument in form and substance reasonably acceptable to the Company.

Section 4.2 Termination of Registration Rights. The rights of any particular Holder to cause the Company to register securities under Article I shall terminate with respect to such Holder upon the date upon which such Holder no longer holds any Registrable Securities.

ARTICLE V

MISCELLANEOUS

Section 5.1 Amendments and Waivers. Subject to applicable law and subject to the other provisions of this Agreement, this Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed on behalf of each of the Purchasers and the Company.

15

Section 5.2 Extension of Time, Waiver. The parties hereto may, to the extent legally allowed and except as otherwise set forth herein: (a) extend the time for the performance of any of the obligations or other acts of the other parties, as applicable; and (b) subject to the requirements of applicable law, waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such extension or waiver will be valid only if set forth in an instrument in writing signed by such party; provided that any Purchaser may execute such waivers on behalf of any Holder. Any failure or delay in exercising any right, power or privilege pursuant to this Agreement will not constitute a waiver of such right, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 5.3 Assignment. Except as provided in Section 4.1, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of law or otherwise, by any of the parties hereto without the prior written consent of the other parties hereto; provided, further, that if the Company consolidates or merges with or into any Person and the Common Stock or any other Registrable Securities are, in whole or in part, converted into or exchanged for securities of a different issuer, and any Holder would, upon completion of such merger or consolidation, hold Registrable Securities of such issuer, then as a condition to such transaction the Company will cause such issuer to assume all of the Company’s rights and obligations under this Agreement in a written instrument delivered to the Holders.

Section 5.4 Counterparts. This Agreement and any amendments hereto may be executed in one or more counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each party forever waives any such defense, except to the extent such defense relates to lack of authenticity.

Section 5.5 Entire Agreement; No Third Party Beneficiary. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Purchase Agreements and the Stockholders Agreement, constitute the entire agreement among the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof. This Agreement is not intended to and shall not confer any rights or remedies upon any person other than the parties hereto, their respective successors and permitted assigns and any Indemnified Party hereunder.

Section 5.6 Governing Law; Jurisdiction.

(a) This Agreement and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of the Purchasers or the Company in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with the laws of the State of Delaware, including its statute of limitations, without giving effect to any choice or conflict of laws 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 the State of Delaware.

16

(b) Each of the parties hereto: (i) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts (as defined below)) in any Legal Proceeding arising out of or relating to this Agreement, in accordance with Section 5.9 or in such other manner as may be permitted by applicable law, and nothing in this Section 5.6(b) will affect the right of any party hereto to serve legal process in any other manner permitted by applicable law; (ii) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, solely if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any other state or federal court within the State of Delaware) (the “Chosen Courts”) in the event of any dispute or controversy relating to or arising out of this Agreement; (iii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (iv) agrees that any Legal Proceeding relating to or arising out of this Agreement will be brought, tried and determined only in the Chosen Courts; (v) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (vi) agrees that it will not bring any Legal Proceeding relating to or arising out of this Agreement in any court other than the Chosen Courts unless the Chosen Courts issue a final judgment determining that such court lacks jurisdiction.

Section 5.7 Specific Enforcement. The parties acknowledge and agree that (a) the parties shall be entitled to an injunction or injunctions, specific performance or other equitable relief to enforce specifically the terms and provisions hereof in the courts described in Section 5.6 without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (b) the right of specific enforcement is an integral part of this Agreement and without that right, neither the Company nor the Purchasers would have entered into this Agreement. The parties hereto agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, and agree not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 5.7 shall not be required to provide any bond or other security in connection with any such order or injunction.

EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS

17

CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTION.
