ARTICLE 2

CONTINGENT VALUE RIGHTS

Section 2.1 Holders of CVRs; Appointment of Rights Agent; Assignment of Rights.

(a) The initial Holders shall be the holders of shares of the Company’s common stock as of the close of business on the Record Date. Effective as of the close of business on the Record Date, each initial Holder shall be issued one CVR for each share of Company common stock held of record by such Holder as of the close of business on the Record Date. Notwithstanding anything to the contrary in this Agreement, in no event shall any CVRs be issued pursuant to this Agreement prior to the Record Date.

(b) The Company hereby appoints the Rights Agent to act as rights agent for the Company in accordance with the express terms and conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment.

(c) The Company hereby irrevocably assigns and agrees to pay to the Holders an amount in cash equal to the TIGIT Payment Amount(s), when, as and if actually received by the Company; provided, that (i) for the avoidance of doubt, the foregoing shall not constitute an assignment of any of the Company’s right, title or interest in and to the right to receive any amounts pursuant to the Celgene Collaboration Agreement or the TIGIT License Agreement and shall only apply with respect to the an amount in cash equal to TIGIT Payment Amount(s), when, as and if actually received by the Company and (ii) the foregoing shall not affect or otherwise modify the remaining terms of this Agreement, including such terms governing the payment and distribution of the TIGIT Payment Amount(s) through the Rights Agent.

Section 2.2 Non-transferable.

A Holder may not at any time Transfer CVRs, other than pursuant to a Permitted Transfer. Any attempted Transfer that is not a Permitted Transfer, in whole or in part, will be void ab initio and of no effect.

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address; CVR Distribution.

(a) Holders’ rights and obligations in respect of CVRs derive solely from this Agreement; CVRs will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will create and maintain a register (the “CVR Register”) for the purposes of (i) identifying the Holders of CVRs, (ii) determining Holders’ entitlement to CVRs and (iii) registering the CVRs and Permitted Transfers thereof. The CVR Register will be created, and CVRs will be distributed, pursuant to written instructions to the Rights Agent from Company. Except for the obligations to the Rights Agent set forth herein, neither the Company nor its Subsidiaries will have any responsibility or liability whatsoever to any Person other than the Holders.

(c) Subject to the restriction on transferability set forth in Section 2.2, every request made to Transfer CVRs must be in writing and accompanied by a written instrument of Transfer reasonably acceptable to the Rights Agent, together with the signature guarantee of a guarantor institution which is a participant in a signature guarantee program approved by the Securities Transfer Association (a “signature guarantee”) and other requested documentation in a form reasonably satisfactory to the Rights Agent, duly executed and properly completed, as applicable, by the Holder or Holders thereof, or by the duly appointed legal representative, personal representative or survivor of such Holder or Holders, setting forth in reasonable detail the circumstances relating to the Transfer. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination in accordance with its own internal procedures, that the Transfer instrument is in proper form and the Transfer is a Permitted Transfer and otherwise

complies on its face with the other terms and conditions of this Agreement, register the Transfer of the applicable CVRs in the CVR Register. All Transfers of CVRs registered in the CVR Register will be the valid obligations of the Company, evidencing the same right, and entitling the transferee to the same benefits and rights under this Agreement, as those held by the transferor. The Company and the Rights Agent may each require payment of a sum sufficient to cover any stamp or other transfer tax or governmental charge that is imposed in connection with (and would not have been imposed but for) any such registration of transfer. No transfer of CVRs shall be valid until registered in the CVR Register and any transfer not duly registered in the CVR Register shall be void.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. Such written request must be duly executed by such Holder. Upon receipt of such written notice, the Rights Agent shall promptly record the change of address in the CVR Register.

(e) The Company will provide written instructions to the Rights Agent for the distribution of CVRs to the Holders as of the Record Date. Company shall inform Rights Agent of the Record Date at least five business days prior thereto. Subject to the terms and conditions of this Agreement and the Company’s confirmation of the Record Date, the Rights Agent hereunder shall make the CVR distribution, less any applicable tax withholding, to each Holder as of the Record Date by the mailing of a statement of holding reflecting CVRs.

Section 2.4 Payment Procedures.

(a) If a Payment Triggering Event occurs at any time prior to the termination of this Agreement, then, within thirty (30) Business Days after the occurrence of such Payment Triggering Event, the Company, or a Person nominated by the Company (with written notice thereof from the Company to the Rights Agent), as the case may be, will deliver to the Rights Agent (i) an Officer’s Certificate certifying the date of the Payment Triggering Event, the amount of the payment and that the Holders are entitled to receive the applicable TIGIT Payment Amount in respect thereof (the “Payment Triggering Event Notice”), and (ii) an amount in cash equal to the applicable TIGIT Payment Amount (for further distribution to the Holders in accordance with the terms hereof) by wire transfer of immediately available funds to an account designated by the Rights Agent.

(b) Upon receipt of the wire transfer referred to in Section 2.4(a), the Rights Agent will promptly (and in any event within ten (10) Business Days) pay, by check mailed, first-class postage prepaid, to the address of each Holder set forth in the CVR Register at such time or by other method of delivery as specified by the applicable Holder in writing to the Rights Agent, an amount in cash equal to such Holder’s Pro Rata Share of the applicable TIGIT Payment Amount.

(c) With respect to any TIGIT Payment Amount, the Company shall have no further liability in respect of such TIGIT Payment Amount upon delivery of the relevant funds to the Rights Agent in accordance with Section 2.4(a).

(d) The Company and the Rights Agent will be entitled to deduct and withhold, or cause to be deducted and withheld, from any TIGIT Payment Amount otherwise payable pursuant to this Agreement, such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of applicable Law relating to Taxes. To the extent that amounts are so deducted and withheld, such deducted and withheld amounts will be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made. Prior to making any such Tax deductions or withholdings or causing any such Tax deductions or withholdings to be made with respect to any Holder, the Rights Agent will, to the extent reasonably practicable, provide notice to the Holder of such potential Tax deduction or withholding and a reasonable opportunity for the Holder to provide any necessary Tax forms in order to avoid or reduce such withholding amounts; provided that the time period for payment of a TIGIT Payment Amount by the Rights Agent set forth in Section 2.4(b) will be extended by a period equal to any delay caused by the Holder providing such forms, provided, further, that in no event shall such period be extended for more than ten (10) Business Days, unless otherwise requested by the Holder for the purpose of delivering such forms and agreed to by the Rights Agent.

(e) Any portion of a TIGIT Payment Amount that remains undistributed to the Holders on the date that is six (6) months after the Rights Agent’s receipt of the applicable Payment Triggering Event Notice (including by means of uncashed checks or invalid addresses on the CVR Register) will be delivered by the Rights Agent to the Company or a Person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent), and any Holder will thereafter look only to the Company for payment of such TIGIT Payment Amount (which shall be without interest).

(f) If any TIGIT Payment Amount (or portion thereof) remains unclaimed by a Holder on the date that is four (4) years after the Rights Agent’s receipt of the applicable Payment Triggering Event Notice (or immediately prior to such earlier date on which such TIGIT Payment Amount would otherwise escheat to or become the property of any governmental authority), then: (i) such TIGIT Payment Amount (or portion thereof) will, to the extent permitted by applicable Law, become the property of the Company and will be transferred to the Company or a Person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent), free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor, and (ii) the CVRs to which such payment relate shall, to the extent permitted by applicable Law, be deemed abandoned in accordance with Section 2.6 and, from and after the date of such abandonment, shall no longer be deemed outstanding for any purpose (including for purposes of calculating a Holder’s Pro Rata Share from and after the date of such abandonment). Neither the Company nor the Rights Agent will be liable to any Person in respect of a TIGIT Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law. In addition to and not in limitation of any other indemnity obligation herein, the Company 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 the Company or a public official.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest.

(a) CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable in respect of CVRs.

(b) CVRs will not represent any equity or ownership interest in the Company or any of its Affiliates. The sole right of the Holders to receive property hereunder is the right to receive TIGIT Payment Amounts, if any, in accordance with the terms hereof. It is hereby acknowledged and agreed that a CVR shall not constitute a security of the Company or any of its Affiliates.

Section 2.6 Ability to Abandon CVR.

A Holder may at any time, at such Holder’s option or upon the failure to claim payment under Section 2.4(f), abandon all of such Holder’s remaining rights represented by CVRs by transferring such CVR to the Company or a Person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent) without consideration in compensation therefor, and such rights will be cancelled, with the Rights Agent being promptly notified in writing by the Company of such transfer and cancellation. No such notice to the Rights Agent shall be required in the case of abandonment due to the failure to claim payment under Section 2.4(f). Nothing in this Agreement is intended to prohibit the Company or its Affiliates from offering to acquire or acquiring CVRs, in private transactions or otherwise, for consideration in its sole discretion.

ARTICLE 3

THE RIGHTS AGENT

Section 3.1 Certain Duties and Responsibilities.

(a) The Rights Agent will not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent such liability arises as a result of the willful misconduct, bad faith or gross negligence of the Rights Agent (in each case as determined by a final non-appealable judgment of court of competent jurisdiction). Notwithstanding anything in this Agreement to the contrary, any liability of the Rights Agent under this Agreement will be limited to the amount of annual fees paid by the Company to the Rights Agent during the twelve (12) months immediately preceding the event for which recovery from the Rights Agent is being sought. Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action.

(b) The Rights Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any Holder with respect to any action or default by any Person or entity, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon the Company. All rights of action under this Agreement may be enforced (but shall not be required to be enforced) by the Rights Agent, any claim, action, suit, audit, investigation or proceeding instituted by the Rights Agent will be brought in its name as the Rights Agent and any recovery in connection therewith will be for the proportionate benefit of all the Holders, as their respective rights or interests may appear on the CVR Register.

Section 3.2 Certain Rights of Rights Agent.

(a) The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied covenants or obligations will be read into this Agreement against the Rights Agent.

(b) The Rights Agent may rely and will be protected by the Company in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in the absence of bad faith to be genuine and to have been signed or presented by or on behalf of the Company.

(c) Whenever the Rights Agent deems it desirable that a matter be proved or established prior to taking or omitting any action hereunder, the Rights Agent may (i) rely upon an Officer’s Certificate and (ii) incur no liability and be held harmless by the Company for or in respect of any action taken or omitted to be taken by it under the provisions of this Agreement in reliance upon such Officer’s Certificate.

(d) The Rights Agent may engage and consult with counsel of its selection, and the advice or opinion of such counsel will, in the absence of bad faith, gross negligence or willful misconduct on the part of the Rights Agent, be full and complete authorization and protection in respect of any action taken or not taken by the Rights Agent in reliance thereon.

(e) Any permissive rights of the Rights Agent hereunder will not be construed as a duty.

(f) The Rights Agent will not be required to give any note or surety in respect of the execution of its powers or otherwise under this Agreement.

(g) The Company agrees to indemnify the Rights Agent for, and to hold the Rights Agent harmless from and against, any loss, liability, damage, judgment, fine, penalty, cost or expense (each, a “Loss”) suffered or incurred by the Rights Agent and arising out of or in connection with the Rights Agent’s performance of its obligations under this Agreement, including the reasonable and documented costs and expenses of defending the Rights Agent against any claims, charges, demands, actions or suits arising out of or in connection in connection with the execution, acceptance, administration, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder, except to the extent such Loss has been determined by a final non-appealable decision of a court of competent jurisdiction to have resulted from the Rights Agent’s gross negligence, bad faith or willful misconduct.

(h) In addition to the indemnification provided under Section 3.2(g), the Company agrees (i) to pay the fees of the Rights Agent in connection with the Rights Agent’s performance of its obligations hereunder, as agreed upon in writing by the Rights Agent and the Company on or prior to the date of this Agreement, and (ii) to reimburse the Rights Agent for all reasonable and properly documented out-of-pocket expenses, including all Taxes (other than income, receipt, franchise or similar Taxes) and governmental charges, incurred by the Rights Agent in the performance of its obligations under this Agreement, except that the Company will have no obligation to pay the fees of the Rights Agent or reimburse the Rights Agent in connection with any lawsuit initiated by the Rights Agent on behalf of itself or the Holders, except in the case of any suit enforcing the provisions of Section 2.4(b) or Section 3.2(g), if the Company is found by a court of competent jurisdiction to be liable to the Rights Agent or the Holders, as applicable in such suit.

(i) 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 any of its rights or powers if it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(j) The Rights Agent will not be deemed to have knowledge of any event of which it was supposed to receive notice hereunder but has not received written notice of such event, and the Rights Agent will not incur any liability for failing to take action in connection therewith, in each case, unless and until it has received such notice in writing.

The Rights Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any Holders with respect to any action or default by the Company, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon the Company.

(p) The Rights Agent may rely on and be fully authorized and protected in acting or failing to act upon (a) any guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program” or insurance program in addition to, or in substitution for, the foregoing; or (b) any law, act, regulation or any interpretation of the same even though such law, act, or regulation may thereafter have been altered, changed, amended or repealed.

(q) The Rights Agent shall not be liable or responsible for any failure of the Company to comply with any of its obligations relating to any registration statement filed with the Securities and Exchange Commission or this Agreement, including without limitation obligations under applicable regulation or law.

(r) The obligations of the Company under this Section 3.2 shall survive the expiration of the CVRs and the termination of this Agreement and the resignation, replacement or removal of the Rights Agent.

Section 3.3 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by written notice to the Company. Any such resignation notice shall specify the date on which such resignation will take effect (which shall be at least thirty (30) days following the date that such resignation notice is delivered), and such resignation will be effective on the earlier of (x) the date so specified and (y) the appointment of a successor Rights Agent.

(b) The Company will have the right to remove the Rights Agent at any time by written notice to the Rights Agent, specifying the date on which such removal will take effect. Such notice will be given at least thirty (30) days prior to the date so specified (or, if earlier, the appointment of the successor Rights Agent).

(c) If the Rights Agent resigns, is removed or becomes incapable of acting, the Company will promptly appoint a qualified successor Rights Agent. Notwithstanding the foregoing, if the Company fails to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then the incumbent Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. The successor Rights Agent so appointed will, upon its acceptance of such appointment in accordance with this Section 3.3(c) and Section 3.4, become the Rights Agent for all purposes hereunder.

In the event that any provision of this Agreement, or the application of any such provision to any Person or set of circumstances, is for any reason determined to be invalid, unlawful, void or unenforceable to any extent, the remainder of this Agreement, and the application of such provision to Persons or circumstances other than those as to which it is

determined to be invalid, unlawful, void or unenforceable, will not be impaired or otherwise affected and will continue to be valid and enforceable to the fullest extent permitted by applicable Law.

This Agreement or any counterpart may be executed and delivered by facsimile copies or delivered by electronic communications by portable document format (.pdf), each of which shall be deemed an original. This Agreement will become effective when each party hereto will have received a counterpart hereof signed by the other party hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement will have no effect and no party will have any right or obligation hereunder (whether by virtue of any oral or written agreement or any other communication).

This Agreement will automatically terminate and be of no further force or effect and, except as provided in Section 3.2, the parties hereto will have no further liability hereunder, and the CVRs will expire without any consideration or compensation therefor upon the earliest to occur of (a) if the TIGIT License Agreement has not been entered into in connection with the exercise by Celgene of the Celgene Option with respect to the TIGIT Program, the expiration or termination of the Celgene Collaboration Agreement, and (b) if the TIGIT License Agreement has been entered into in connection with the exercise by Celgene of the Celgene Option with respect to the TIGIT Program, the expiration or termination of the TIGIT License Term; provided, that in the event that any rights to the payments described in clauses (i) and (ii) of the definition of Payment Triggering Event have otherwise accrued under the TIGIT License Agreement prior to such expiration or termination, this Agreement shall not terminate pursuant to this clause (b) until all such accrued amounts have been paid by Celgene to the Company and the applicable TIGIT Payment Amounts in respect thereof have been distributed to Holders hereunder; provided, further, that in the event that Section 6 of the TIGIT License Agreement survives such expiration or termination of the TIGIT License Term, this Agreement shall not terminate pursuant to this clause (b) until Celgene no longer has any obligations pursuant to Section 6 of the TIGIT License Agreement in respect of the payments described in clauses (i) and (ii) of the definition of Payment Triggering Event.

(b) The Company shall keep, and shall require its Affiliates to keep, complete and accurate books and records that may be necessary for the purpose of calculating the TIGIT Payment Amounts payable under this Agreement.

Upon at least ten (10) Business Days’ prior written notice from a Majority of Holders, such audit shall be conducted during regular business hours in such a manner as to not unnecessarily interfere with the Company’s normal business activities.
