ARTICLE II

Contingent Value Rights

2.1 CVRs. The CVRs represent the rights of Holders to receive contingent cash payments pursuant to this Agreement. The initial Holders shall be the (i) holders of Shares other than Excluded Shares immediately prior to the Effective Time and (ii) holders of Company Options and Company RSUs immediately prior to the Effective Time whose Company Options and Company RSUs are converted into the right to receive the Per Share Merger Consideration pursuant to Article IV of the Merger Agreement.

2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. Any attempted transfer, in whole or in part, that is not a Permitted Transfer, will be void ab initio and of no effect.

-5-

2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs shall not be evidenced by a certificate or other instrument.

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purpose of registering CVRs and transfers of CVRs as herein provided. The CVRs shall, in the case of the holders of Shares immediately prior to the Effective Time, other than the Excluded Shares, be registered in the names and addresses of the holder as set forth in the form Parent Holdco furnishes or causes to be furnished to the Rights Agent pursuant to Section 4.1, and in a denomination equal to the number of Shares converted into the right to receive the Per Share Merger Consideration. The CVR Register will initially show one position for Cede & Co representing all Shares held by DTC on behalf of street holders held by such holders as of immediately prior to the Effective Time. In the case of RSU Holders and Option Holders, the CVRs shall be registered in the names and addresses of such RSU Holder or Option Holder, as applicable, and in a denomination equal to the number of Shares subject to the outstanding restricted stock units held by such RSU Holder immediately prior to the Effective Time or the number of Shares underlying the outstanding stock options held by such Option Holder immediately prior to the Effective Time, as applicable, and, in each case, as set forth in a schedule delivered by the Company to Parent Holdco (the “Equity Awards Schedule”). The Rights Agent hereby acknowledges the restrictions on transfer contained in Section 2.2 and agrees not to register a transfer which does not comply with Section 2.2.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer and other requested documentation in form reasonably satisfactory to the Rights Agent pursuant to its customary policies and guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or the Holder’s survivor, and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. Any transfer of CVRs will be without charge (other than the cost of any Tax) to the applicable Holder. The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment by a Holder of a CVR of applicable Taxes or charges unless and until the Rights Agent is satisfied that all such Taxes or charges have been paid. All duly transferred CVRs registered in the CVR Register shall be the valid obligations of Parent Holdco and shall entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR shall be valid until registered in the CVR Register.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the written notice is in proper form, promptly record the change of address in the CVR Register.

2.4 Payment Procedures.

(a) If the Milestone occurs at any time prior to the expiration of the Milestone Period, then, on or prior to the Milestone Payment Date, Parent Holdco will deliver or cause to be delivered to the Rights Agent (i) a certificate (the “Milestone Achievement Certificate”) certifying the date of the satisfaction of the Milestone and that the Holders are entitled to receive the Milestone Payment and (ii) a wire transfer of immediately available funds to an account designated by the Rights Agent, in the aggregate amount equal to the number of CVRs (as reflected in the CVR Register) then outstanding multiplied by the amount of the Milestone Payment (the “Aggregate Milestone Payment”). After receipt of the wire transfer described in the foregoing sentence, the Rights Agent will promptly (and in any event, within five (5) Business Days) pay (x) by one lump sum wire payment to DTC for any Holder who is a former street name holder of Shares and (y) for all other Holders, by check mailed, first-class postage prepaid, to the address of each Holder set forth in the CVR Register or by other method of delivery as specified by the applicable Holder in writing to the Rights Agent (such amount in (x) and (y) together, an amount in cash equal to Aggregate Milestone Payment). The Rights Agent shall hold the Aggregate Milestone Payment in a non-interest bearing account until such payment is made in accordance with the foregoing sentence. Notwithstanding the foregoing, in no event shall Parent Holdco be required to pay the Milestone Payment more than once and Parent Holdco shall not be required to pay the Milestone Payment if the Milestone occurs after the expiration of the Milestone Period.

(b) Parent Holdco or the Rights Agent shall be entitled to deduct or withhold from the Milestone Payment, if payable, such amounts as may be required to be deducted or withheld with respect to the Milestone Payment or CVR under the Code, and the rules and regulations thereunder, or any other applicable provision of state, local or foreign Law relating to Taxes, as may be reasonably determined by Parent Holdco or the Rights Agent. Prior to making any such Tax withholdings or causing any such Tax withholdings to be made with respect to any Holder, the Rights Agent shall, to the extent practicable, provide notice to the Holder of such potential withholding and, if applicable, a reasonable opportunity for the Holder to provide any necessary Tax forms in order to reduce or eliminate such withholding amounts. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid, and prior to the fifteenth (15th) day of February in the year following any payment of such Taxes by Parent Holdco or the Rights Agent, the Rights Agent shall deliver to the person to whom such amounts would otherwise have been paid the original Form 1099 or other reasonably acceptable evidence of such withholding.

-7-

(c) Any portion of any Milestone Payment that remains undistributed to the Holders six (6) months after the date of the Milestone Achievement Certificate shall be delivered by the Rights Agent to Parent Holdco, upon demand, and any Holder shall thereafter look only to Parent Holdco for payment of such Milestone Payment, without interest, but such Holder shall have no greater rights against Parent Holdco than those accorded to general unsecured creditors of Parent Holdco under applicable Law.

(d) Neither Parent Holdco nor the Rights Agent shall be liable to any person in respect of any Milestone Payment delivered to a public official in compliance with any applicable state, federal or other abandoned property, escheat or similar Law. If, despite Parent Holdco’s and/or the Rights Agent’s reasonable best efforts to deliver a Milestone Payment to the applicable Holder, such Milestone Payment has not been paid prior to the date on which such Milestone Payment would otherwise escheat to or become the property of any Governmental Entity, any such Milestone Payment shall, to the extent permitted by applicable Law, immediately prior to such time become the property of Parent Holdco, free and clear of all claims or interest of any person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, Parent Holdco agrees to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to Parent Holdco.

(e) Except to the extent any portion of any Milestone Payment is required to be treated as imputed interest pursuant to applicable Law, the Parties agree to treat the CVRs and the Milestone Payment received with respect to the Shares pursuant to the Merger Agreement for all U.S. federal and applicable state and local income Tax purposes as additional consideration for the Shares and none of the Parties will take any position to the contrary on any U.S. federal and applicable state and local income Tax Return or for other U.S. federal and applicable state and local income Tax purposes except as required by applicable Law.

(f) The Parties agree, to the extent consistent with applicable law, to treat the payments from the CVRs received with respect to the Company RSUs and Company Options for all U.S. federal and applicable state and local income Tax purposes as compensation payments (and not to treat the CVR as a payment itself).

2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent Holdco.

(a) The CVRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the CVRs to any Holder.

The CVRs shall not represent any equity or ownership interest in Parent Holdco or in any constituent company to the Merger or any of their respective Affiliates.

(d) the permissive rights of the Rights Agent to do things enumerated in this Agreement shall not be construed as a duty;

(e) the Rights Agent shall not be required to give any note or surety in respect of the execution of such powers;

(f) the Rights Agent shall not be liable for or by reason of, and shall be held harmless by Parent Holdco with respect to any of the statements of fact or recitals contained in this Agreement or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by Parent Holdco only;

-9-

(g) the Rights Agent shall have no liability and shall be held harmless by Parent Holdco in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution and delivery hereof by the Rights Agent and the enforceability of this Agreement against the Rights Agent assuming the due execution and delivery hereof by Parent Holdco), nor shall it be responsible for any breach by Parent Holdco of any covenant or condition contained in this Agreement;

The Rights Agent shall also be entitled to reimbursement from Parent Holdco for all reasonable and documented out-of-pocket expenses paid or incurred by it in connection with the administration by the Rights Agent of its duties hereunder; and

(k) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

3.3 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent Holdco specifying a date when such resignation shall take effect, which notice shall be sent at least thirty (30) days prior to the date so specified, but in no event shall such resignation become effective until a successor Rights Agent has been

appointed. Parent Holdco has the right to remove the Rights Agent at any time by a Board Resolution specifying a date when such removal shall take effect, but no such removal shall become effective until a successor Rights Agent has been appointed. Notice of such removal shall be given by Parent Holdco to the Rights Agent, which notice shall be sent at least thirty (30) days prior to the date so specified.

The successor Rights Agent so appointed shall, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

6.5 Governing Law; Jurisdiction; WAIVER OF JURY TRIAL.

(a) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED IN ACCORDANCE WITH, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO CONFLICTS OF LAWS PRINCIPLES THEREOF THAT WOULD RESULT IN THE APPLICATION OF THE LAW OF ANY OTHER STATE OR WOULD DIRECT A MATTER TO ANOTHER JURISDICTION. Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America located in the County of New Castle, Delaware, and any appellate court from any thereof, solely in respect of the interpretation and enforcement of the provisions of (and any claim or cause of action arising under or relating to) this Agreement and of the documents referred to in this

-16-

Agreement, and in respect of the transactions contemplated hereby, and each of the Parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America located in the County of New Castle, Delaware, as applicable, and any appellate court from any thereof, (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America located in the County of New Castle, Delaware, as applicable, and any appellate court from any thereof, (iii) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in such courts and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in such courts. Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each Party irrevocably consents to and grants any such court jurisdiction over the person of such parties and, to the extent permitted by Law, over the subject matter of such dispute and consents to service of process inside or outside the territorial jurisdiction of the courts referred to in this Section 6.5(a) in the manner provided for notices in Section 6.2. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Law.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE MERGER AND OTHER TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES SUCH WAIVERS VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.5(b).

-17-

6.6 Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

6.7 Entire Agreement. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.

6.8 Third-Party Beneficiaries; Action by Acting Holders. Parent Holdco and the Rights Agent hereby agree that the respective covenants and agreements set forth herein are intended to be for the benefit of, and shall be enforceable by, the Acting Holders, who are intended third-party beneficiaries hereof. Parent Holdco and the Rights Agent further agree that this Agreement and their respective covenants and agreements set forth herein are solely for the benefit of Parent Holdco, the Rights Agent, the Holders and their permitted successors and assigns hereunder in accordance with and subject to the terms of this Agreement, and nothing in this Agreement, express or implied, will confer upon any Person other than Parent Holdco, the Rights Agent, the Holders and their permitted successors and assigns hereunder any benefit or any legal or equitable right, remedy or claim hereunder. Except for the right of the Rights Agent set forth herein, the Acting Holders will have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights. The parties hereto hereby agree that irreparable damage may occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies may not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach or threatened breach by Parent Holdco or Assignee (as such term is defined below), on the one hand, or the Rights Agent or the Acting Holders, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, Parent Holdco or Assignee, on the one hand, and the Rights Agent or the Acting Holders, on the other hand, shall be entitled to seek an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, by the other(s) (as applicable), and to seek specific enforcement of the terms and provisions of this Agreement.

6.9 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the

-18-

validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.

6.10 Assignment. This Agreement shall not be assignable provided, however, that (a) Parent Holdco may assign this agreement to a Person (each such Person, an “Assignee”) (i) which is a direct or indirect wholly-owned subsidiaries of Parent Holdco, provided that Parent Holdco remains jointly and severally liable, (ii) with the prior consent of the Acting Holders, whether evidenced in writing or taken at a meeting of the Holders, or (iii) in connection with a transaction involving an Assignment Transaction conducted in compliance with Section 4.3 and (b) the Rights Agent may assign this Agreement to a successor Rights Agent appointed in accordance with Section 3.3.

6.11 Benefits of Agreement. Notwithstanding anything to the contrary contained herein, any Holder may at any time agree to renounce, in whole or in part, whether or not for consideration, such Holder’s rights under this Agreement by written notice to the Rights Agent and Parent Holdco, which notice, if given, shall be irrevocable. Parent Holdco may, in its sole discretion, at any time, offer consideration to Holders in exchange for their agreement to irrevocably renounce their rights hereunder.

6.12 Legal Holidays. In the event that any Milestone Payment Date shall not be a Business Day, then (notwithstanding any provision of this Agreement to the contrary) payment need not be made on such date, but may be made, without the accrual of any additional interest thereon on account of such Milestone Payment Date not being a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Milestone Payment Date.

6.13 Interpretation; Construction.

(a) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof.

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.
