(b) Concurrently with the Royalty Reports and CVT Officer’s Certificates provided to TPG-Axon pursuant to Sections 3.2, 3.3 and 3.4, as applicable, CVT shall prepare and send to TPG-Axon a draft of CVT’s proposed instructions to JPMorgan detailing what amounts (including reasonable supporting calculations) deposited in the Joint Concentration Account and corresponding to such Royalty Reports and CVT Officer’s Certificates should be transferred from the Joint Concentration Account to each of the CVT Concentration Account and the TPG-Axon Concentration Account, consistent with the terms and conditions of this Agreement (including, without limitation, this Article 3) and the Deposit Agreement (“Draft Instructions”). Any Draft Instructions mutually agreed upon by the Parties and any Draft Instructions deemed to be accepted by TPG-Axon under this Section 3.1(b) shall be referred to herein as the “Final Instructions.” TPG-Axon shall respond to CVT in writing within [****] with respect to any Draft Instructions from CVT hereunder, indicating whether or not TPG-Axon agrees with such Draft Instructions as Final Instructions. If TPG-Axon so notifies CVT that TPG-Axon does not agree with the Draft Instructions, the Parties shall attempt to reach agreement in writing on Draft Instructions as promptly as possible, consistent with the [****] time periods set forth in Sections 3.5, 3.9 and 3.10 for the Parties to resolve disagreements regarding payment calculations. If TPG-Axon fails to provide any notice

to CVT within the [****] time period set forth above, TPG-Axon shall be deemed to have accepted the Draft Instructions as Final Instructions. TPG-Axon shall, within [****] of its deemed acceptance or the Parties’ mutual agreement upon Final Instructions in accordance with this Section 3.1(b), send the Final Instructions to JPMorgan as Account Instructions. In addition, if CVT is delivering Draft Instructions to TPG-Axon hereunder prior to the end of the then-current quarter but later than the [****] prior to the expiration of such applicable Calendar Quarter, CVT shall send TPG-Axon together with the Draft Instructions a set of alternative instructions (“Alternative Instructions”) instructing JPMorgan to retain in the Joint Concentration Account at the expiration of the applicable Calendar Quarter (but not at the expiration of any ensuing Calendar Quarter) the amounts deposited in the Joint Concentration Account and corresponding to such Royalty Reports and CVT Officer’s Certificates, pending determination by the Parties of the treatment of those amounts in accordance with the other provisions of this Agreement. In the event TPG-Axon receives any Alternative Instructions from CVT hereunder, TPG-Axon may, prior to the expiration of the applicable Calendar Quarter to which such Alternative Instructions pertain, send the Alternative Instructions to JPMorgan as Account Instructions, and concurrently notify CVT in writing that TPG-Axon has done so.

(c) Notwithstanding any other provisions of this Section 3.1, each Party may communicate directly with JPMorgan with respect to ministerial matters not relating to the disposition, transfer, withdrawal, disbursement or redemption of any amounts in or credits to the Joint Concentration Account (e.g., to notify JPMorgan of such Party’s change of address or contact party, etc.), without the other Party’s prior consent to or agreement upon the contents of such communication, provided that the Party so communicating to JPMorgan will concurrently provide to the other Party a copy of such ministerial communication.

3.2 Royalty Reports. (A) Within [****] of CVT’s receipt of any report of Regadenoson Net Sales provided by Astellas pursuant to Section 5.7 of the Astellas Agreement (each, a “Royalty Report”) or (B) if the amount relating to the applicable Royalty Report is not deposited into the Joint Concentration Account by Astellas prior to or concurrently with (or within [****] thereafter) the delivery to CVT of the applicable Royalty Report, within [****] of CVT’s Knowledge of a deposit being made into the Joint Concentration Account or, if later, receipt of a notice from JPMorgan pursuant to the Deposit Agreement confirming that Astellas has deposited an amount into the Joint Concentration Account, which deposit or amount, as applicable, relates to the applicable Royalty Report (and which Royalty Report was previously received by CVT), CVT shall (a) to the extent delivery of such Royalty Report to TPG-Axon is not prohibited by obligations of confidentiality between Astellas and CVT contained in the Astellas Agreement, provide a copy of such Royalty Report to TPG-Axon or (b) to the extent delivery of such Royalty Report is prohibited by obligations of confidentiality between Astellas and CVT contained in the Astellas Agreement, provide a certificate (a “CVT Officer’s Certificate”) executed by the Chief Executive Officer or Chief Financial Officer, or other applicable officer of CVT, dated the date of delivery, certifying, to the Knowledge of CVT:

(i)

whether the amount deposited into the Joint Concentration Account for the applicable period for which payments are provided by Astellas concurrently with the delivery of the applicable Royalty Report by Astellas to CVT equals the amount of the Regadenoson Royalty to which CVT is entitled under the Astellas Agreement (the “Applicable Amount”);

(ii)

to the extent the amount so deposited into the Joint Concentration Account is not the Applicable Amount, the basis for the disparity (e.g., a Deficient Payment, Astellas including other amounts owing from it to CVT under the Astellas Agreement, such as, but not limited to, payments under [****] or other Excluded Payments in the amount so deposited in the Joint Concentration Account or Astellas sending payments for the Regadenoson Royalty to CVT rather than the Joint Concentration Account) and the amount of the disparity;

(iii)

whether the amount so deposited into the Joint Concentration Account was subject to any Offset by Astellas and, if so, the basis for the Offset (including the applicable section of the Astellas Agreement on which the Offset was based, or, if applicable, any other basis for the Offset) and its amount;

(iv)

whether the amount so deposited into the Joint Concentration Account was subject to any [****] and, if so, the amount of [****];

(v)

whether the amount so deposited into the Joint Concentration Account includes any Related Regadenoson Payments or any other amounts (other than amounts otherwise described in such CVT Officer’s Certificate) to which TPG-Axon is entitled under this Agreement and, if so, their basis and amount;

(vi)

whether the amount so deposited into the Joint Concentration Account is less than the Applicable Amount due to the failure of Astellas to make the applicable payment to the Joint Concentration Account or CVT, in which case such certificate shall also describe in reasonable detail the [****] and CVT’s [****]; and

(vii)

whether the amount so deposited into the Joint Concentration Account included any Excluded Payments or Overpayment Amounts, and, if so, their basis and amount.

To the extent the amount so deposited into the Joint Concentration Account is otherwise different than the Applicable Amount, such certificate shall also describe in reasonable detail the [****] to ensure that all amounts required to be sent to the Joint Concentration Account by Astellas pursuant to the Astellas Notice or CVT pursuant to this Agreement are so sent and [****].

3.3 Related Regadenoson Payments. Within [****] of any Related Regadenoson Payments, or any other amounts to which TPG-Axon is entitled under this Agreement, being deposited in the Joint Concentration Account in circumstances where Regadenoson Royalty payments are not also deposited, CVT shall deliver to TPG-Axon a CVT Officer’s Certificate dated the date of delivery, certifying as to the matters covered by the CVT Officer’s Certificate under Section 3.2, with appropriate adjustments to reflect that the amount deposited consisted of Related Regadenoson Payments and/or other amounts to which TPG-Axon is entitled under this Agreement rather than Regadenoson Royalty payments.

3.4 CVT’s Receipt of Payments. Upon receipt of any payments by CVT for any Regadenoson Royalty or any Related Regadenoson Payments or any other amounts to which TPG-Axon is entitled under this Agreement, CVT shall hold (a) fifty percent (50%) of such payments in trust for the benefit of TPG-Axon on account of its ownership of the Assigned Rights, in the case of any payments for any Regadenoson Royalty or any Related Regadenoson Payment or (b) all of such amounts in trust for the benefit of TPG-Axon, in the case of other amounts (if any) to which TPG-Axon is entitled under this Agreement, and shall deposit all of such payments into the Joint Concentration Account as follows: (i) within [****] of CVT’s receipt of such payments to the extent the payments received include any on-time quarterly Regadenoson Royalty payment pursuant to Section 5.7 of the Astellas Agreement or (ii) otherwise within [****] of the receipt by CVT of such payments. Concurrently with the deposit of such payments, CVT shall deliver to TPG-Axon a CVT Officer’s Certificate dated the date of delivery, certifying as to the matters covered by the CVT Officer’s Certificate under Section 3.2 or Section 3.3, as applicable, and with appropriate adjustments to reflect that the amount being deposited is being deposited by CVT rather than Astellas.

3.5 Offsets. Because TPG-Axon is purchasing the Assigned Rights, the Parties acknowledge that the Assigned Rights are subject to the terms and conditions of the Astellas Agreement relevant to the Assigned Rights. The Parties intend this Section 3.5 to address how certain potential offset and/or reduction provisions under the Astellas Agreement (each specified below) or other potential offsets between CVT and Astellas (if any) will affect the Assigned Rights and payments made on account thereof for purposes of this Agreement. Pursuant to Section 6.1(a), TPG-Axon must consent to [****] The Parties intend and agree that such [****] will [****] pursuant to this Agreement.

(a) Regadenoson-Related Section 5.8(a)(ii)(2) Offsets. In the event that Astellas offsets against a portion of the Regadenoson Royalty under Section 5.8(a)(ii)(2) of the Astellas Agreement any monies, upfront fees, licensing fees, royalties and

milestones paid to a Third Person (other than lump sum payments covered by Section 5.8(a)(ii)(1) of the Astellas Agreement) (a “Section 5.8(a)(ii)(2) Offset”), and provided that the applicable Section 5.8(a)(ii)(2) Offset is due to licenses, fees and other payments permitted under such Section 5.8(a)(ii)(2) in connection with the development, manufacture, export, import, use, offer for sale and/or sale of Regadenoson in the Territory, the following provisions shall apply:

(i)

in connection with the delivery of any Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.4, as applicable, that includes a Section 5.8(a)(ii)(2) Offset, the Parties’ Primary Contacts will discuss the amount of such Section 5.8(a)(ii)(2) Offset and attempt to agree in writing on (A) the portion of such Section 5.8(a)(ii)(2) Offset that is the correct amount of such Section 5.8(a)(ii)(2) Offset under the Astellas Agreement (any such agreed upon amount being referred to as the “Agreed-On Section 5.8(a)(ii)(2) Offset Amount”) and (B) the portion of such Section 5.8(a)(ii)(2) Offset, if any, that is in excess of the correct amount of such Section 5.8(a)(ii)(2) Offset under the Astellas Agreement and the amount of such excess (any such agreed upon amount being referred to as the “Agreed-On Excess Section 5.8(a)(ii)(2) Offset Amount”);

(ii)

to the extent the Parties’ Primary Contacts are unable to agree on the correct amount for a Section 5.8(a)(ii)(2) Offset or as to the amount by which any amount taken as an offset under Section 5.8(a)(ii)(2) of the Astellas Agreement exceeds the correct Section 5.8(a)(ii)(2) Offset (any such disputed amounts being referred to as the “Disputed Section 5.8(a)(ii)(2) Offset Amounts”), within [****] following delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.4, as applicable, each Party shall designate an executive officer to discuss the matter with an executive officer of the other Party and attempt to reach agreement in writing on the Agreed-On Section 5.8(a)(ii)(2) Offset Amount and Agreed-On Excess Section 5.8(a)(ii)(2) Offset Amount within [****] following the end of the prior [****] period (and, if they agree upon the same during such period, such amounts shall no longer be considered Disputed Section 5.8(a)(ii)(2) Offset Amounts but shall become Agreed-On Section 5.8(a)(ii)(2) Offset Amounts and Agreed-On Excess Section 5.8(a)(ii)(2) Offset Amounts);

(iii)

the payments which TPG-Axon is entitled to in payment of the TPG-Axon Royalty Interest shall be reduced based on the applicable Section 5.8(a)(ii)(2) Offset to the extent of the amount calculated by multiplying such Section 5.8(a)(ii)(2) Offset (including

the Agreed-On Section 5.8(a)(ii)(2) Offset Amount, any Agreed-On Excess Section 5.8(a)(ii)(2) Offset Amount and any Disputed Section 5.8(a)(ii)(2) Offset Amount) by [****] by a [****] under the Astellas Agreement for such Calendar Quarter (including, for the avoidance of doubt, all [****]);

(iv)

in the event any Agreed-On Excess Section 5.8(a)(ii)(2) Offset Amount exists, [****];

(v)

In the event Disputed Section 5.8(a)(ii)(2) Offset Amounts exist following expiration of the applicable time period(s) utilized by the Parties under Section 3.5(a)(i) or (ii), then [****]; and

(vi)

In the event any Disputed Section 5.8(a)(ii)(2) Offset Amounts exist following the expiration of the applicable time period(s) utilized by the Parties under Section 3.5(a)(i) and (ii), each Party is free to pursue a resolution of such dispute with the other Party, along with any related matters, in the judicial system (without having to comply with the dispute resolution procedures set forth in Section 9.2) or to otherwise exercise any right or remedy such Party may have against the other Party pursuant to this Agreement.

(b) Other Section 5.8(a)(ii)(2) Offsets (If Any). In the event that, notwithstanding CVT’s covenant set forth in Section 6.5(o) relating to any offset under Section 5.8(a)(ii)(2) of the Astellas Agreement for any Licensed Product other than Regadenoson in the Territory, a Section 5.8(a)(ii)(2) Offset occurs and such Section 5.8(a)(ii)(2) Offset is taken by Astellas due to licenses, fees and other payments permitted under Section 5.8(a)(ii)(2) of the Astellas Agreement in connection with the development, manufacture, export, import, use, offer for sale and/or sale of any Licensed Product other than Regadenoson in the Territory, then, within [****] following delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.4, as applicable, that indicates such Section 5.8(a)(ii)(2) Offset, CVT will, in lieu of its indemnification obligations set forth in Section 8.2, pay directly to TPG-Axon into the TPG-Axon Concentration Account (and not into the Joint Concentration Account) an amount equal to the amount by which TPG-Axon’s payments for the Regadenoson Royalty were reduced based on such Section 5.8(a)(ii)(2) Offset. If CVT makes a payment to TPG-Axon pursuant to this Section 3.5(b), and if [****] for which CVT made such payment hereunder, CVT shall [****]

(c) Section 3.4(c)(ii) Offsets. In the event that, notwithstanding CVT’s covenant set forth in Section 6.5(o), Astellas offsets or deducts CVT’s [****] for [****] against a portion of the Regadenoson Royalty pursuant to Section 3.4(c)(ii) of the Astellas Agreement (a “Section 3.4(c)(ii) Offset”), then within [****] following the delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2 or 3.4, as applicable, that indicates such Section 3.4(c)(ii) Offset, CVT will, in lieu of its

indemnification obligations set forth in Section 8.2, pay directly to [****]. If CVT makes a payment to TPG-Axon pursuant to this Section 3.5(c), and if [****] for which CVT made such payment hereunder, CVT shall [****].

(d) Other Offsets. In the event that, notwithstanding [****] Astellas offsets a portion of the Regadenoson Royalty under any provision of the Astellas Agreement [****] or Astellas offsets [****] CVT or any of its Affiliates and Astellas or any of its Affiliates, [****] (any such offset, an “Other Offset”), the following provisions shall apply:

(i)

in connection with the delivery of any Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.4, as applicable, that includes an Other Offset, the Parties’ Primary Contacts will discuss the nature of the CVT obligation to Astellas giving rise to such Other Offset and the amount of such Other Offset and attempt to agree in writing on (A) whether an actual CVT obligation to Astellas exists that gives rise to such Other Offset and the portion of such Other Offset that correctly represents an actual obligation of CVT to Astellas and the amount of such Other Offset (any such agreed upon amount being referred to herein as the “Agreed-On Other Offset Amount”) and (B) the portion of such Other Offset, if any, that is in excess of the correct amount of such Other Offset (any such agreed upon amount being referred to herein as the “Agreed-On Excess Other Offset Amount”);

(ii)

to the extent the Parties’ Primary Contacts are unable to agree on whether an actual CVT obligation to Astellas exists giving rise to such Other Offset, or the correct amount for an Other Offset or as to the amount by which any amount taken as an offset exceeds the correct Other Offset (any such disputed amounts being referred to as the “Disputed Other Offset Amounts”), within [****] following delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.4, as applicable, each Party shall designate an executive officer to discuss the matter with an executive officer of the other Party and attempt to reach agreement in writing on the Agreed-On Other Offset Amount and the Agreed-On Excess Other Offset Amount within [****] following the end of the prior [****] period (and, if they agree upon the same during such period, such amounts shall no longer be Disputed Other Offset Amounts but shall become Agreed-On Other Offset Amounts and Agreed-On Excess Other Offset Amounts);

(iii)

in the event of any Other Offset, the payments which TPG-Axon is entitled to in payment of the TPG-Axon Royalty Interest shall be reduced based on the applicable Other Offset to the extent of the amount calculated by [****] by [****] and CVT will, within [****] of the

Parties’ agreeing in writing on the amount of such Agreed-On Other Offset Amount, in lieu of its indemnification obligations set forth in Section 8.2, pay directly to [****]. If CVT makes a payment to TPG-Axon pursuant to this Section 3.5(d)(iii), and [****] for which CVT made such payment hereunder, [****];

(iv)

in the event any Agreed-On Excess Other Offset Amount exists, CVT will [****];

(v)

In the event Disputed Other Offset Amounts exist following expiration of the applicable time period(s) utilized by the Parties under Section 3.5(d)(i) or (ii), then [****];

(vi)

In the event any Disputed Other Offset Amounts exist following the expiration of the applicable time period(s) utilized by the Parties under Section 3.5(d)(i) and (ii), each Party is free to pursue a resolution of such dispute with the other Party, along with any related matters, in the judicial system (without having to comply with the dispute resolution procedures set forth in Section 9.2) or to otherwise exercise any right or remedy such Party may have against the other Party pursuant to this Agreement.

3.6 Deficient Payments and Late Payments. In the event that any Regadenoson Royalty payment or Related Regadenoson Payment or other payment to which TPG-Axon is entitled under this Agreement is made when due but is less than the aggregate Regadenoson Royalty or Related Regadenoson Payment or other payment then due under the Astellas Agreement or is entirely not made when due (and such shortfall or late payment is not because of an Offset addressed in Section 3.5(a), Section 3.5(b), Section 3.5(c) or Section 3.5(d) above or because of [****] (in any case, a “Deficient Payment”), then (a) CVT, within [****] of the delivery of any Royalty Report or CVT Officer’s Certificate under Section 3.2, Section 3.3 or Section 3.4, as applicable, that indicates a Deficient Payment or within [****] of when CVT otherwise has Knowledge of a Deficient Payment, will notify TPG-Axon in writing regarding the occurrence of the Deficient Payment and the details of the deficiency; and (b) CVT will [****].

3.7 [****] Matters.

(a) In the event of any [****] of any of its [****] being collectively referred to as [****], CVT, at [****] and at the [****], will promptly [****] which [****] and shall thereafter [****]. Any [****] will be [****] where, subject, in each case, to TPG-Axon’s rights with respect to Account Instructions [****] after [****] of [****] for the [****] in accordance with Section 3.1 and the Deposit Agreement, such [****] shall be [****] in accordance with the provisions of Section 3.1 and the Deposit Agreement.

(b) In the event any [****] CVT may, in its sole discretion, [****] in connection with such [****] if any, by [****] which [****] may include [****] CVT shall notify TPG-Axon in writing if it intends to [****]. If CVT [****] including any [****] CVT will be entitled to [****] with respect to such [****] and CVT will then [****] any amounts that CVT [****] or otherwise pursuant to any [****] with respect to such [****]. Such [****] will then be [****] in accordance with the provisions of Section 3.1 and the Deposit Agreement.

(c) Nothing set forth in this Section 3.7 or Section 6.5(d) shall [****] with regard to any [****] that is not covered by this Agreement.

3.8 Post-Termination Royalty Payments. If, during the Term, the Astellas Agreement is terminated and following such termination Astellas continues to pay royalties to the Joint Concentration Account and/or CVT on post-termination Regadenoson Net Sales in the Territory or is obligated under the Astellas Agreement to continue to pay such royalties, TPG-Axon will continue to be entitled to the TPG-Axon Royalty Interest under this Agreement as if such termination had not occurred. In addition, if, during the Term, the Astellas Agreement is terminated (either in whole or in part, or only with respect to a particular country or countries) and the terminated rights to Regadenoson revert to CVT, then CVT will: (a) use good faith, best efforts to either sublicense or divest the reverted rights to Regadenoson to Third Persons reasonably acceptable to TPG-Axon or commercially sell Regadenoson itself and through its Affiliates in a manner and on terms, in either case, that will reasonably likely result in an economic recovery from such rights that is commensurate with that under the Astellas Agreement and (b) negotiate in good faith and enter into with TPG-Axon an agreement that provides TPG-Axon with a royalty on post-termination Regadenoson sales (if any) and a percentage of Regadenoson outlicensing/disposition proceeds (if any) that is commensurate with the TPG-Axon Royalty Interest.

3.9 Excluded Payments. The Parties recognize that it is possible that Astellas may deposit into the Joint Concentration Account amounts that are Excluded Payments. Accordingly the remainder of this Section 3.9 shall apply where Astellas has deposited into the Joint Concentration Account any Excluded Payment.

(a) In connection with the delivery of any Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.3, as applicable, that includes an Excluded Payment, the Parties’ Primary Contacts will discuss the amount of such Excluded Payment and attempt to agree in writing on the portion of the amount deposited by Astellas into the Joint Concentration Account that correctly represents an actual Excluded Payment, and the amount thereof (any such agreed upon amount being referred to herein as the “Agreed-On Excluded Payment Amount”).

(b) To the extent the Parties’ Primary Contacts are unable to agree on the correct amount of any Excluded Payment (any such disputed amounts being referred to as the “Disputed Excluded Payment Amounts”), within [****] following delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2 or Section 3.3,

as applicable, each Party shall designate an executive officer to discuss the matter with an executive officer of the other Party and attempt to reach agreement in writing on the Agreed-On Excluded Payment Amount within [****] following the end of the prior [****] period (and, if they agree upon the same during such period, such amount shall no longer be Disputed Excluded Payment Amounts but shall become Agreed-On Excluded Payment Amounts).

(c) With respect to the amount of any Agreed-On Excluded Payment Amount deposited into the Joint Concentration Account, the Parties agree that, subject to TPG-Axon’s rights with respect to Account Instructions during a CVT Event of Default as set forth in Section 3.1, the Final Instructions shall require JPMorgan to transfer one hundred percent (100%) of the Agreed-On Excluded Payment Amount from the Joint Concentration Account into the CVT Concentration Account before effecting any other transfer from the Joint Concentration Account provided for in such Final Instructions.

(d) In the event Disputed Excluded Payment Amounts exist following the expiration of the applicable time period(s) utilized by the Parties under Sections 3.9(a) and (b), each Party is free to pursue a resolution of such dispute with the other Party, along with any related matters, in the judicial system (without having to comply with the dispute resolution procedures set forth in Section 9.2) or to otherwise exercise any right or remedy such Party may have against the other Party pursuant to this Agreement.

3.10 Overpayments. The Parties recognize that it is possible that Astellas may deposit into the Joint Concentration Account or may pay directly to CVT amounts with respect to the Regadenoson Royalty or the Related Regadenoson Payments that exceed amounts actually due to CVT under the Astellas Agreement at such time (such amounts being referred to herein as “Overpayment Amounts”). Accordingly the remainder of this Section 3.10 shall apply where Astellas has deposited into the Joint Concentration Account any Overpayment Amounts.

(a) In connection with the delivery of any Royalty Report or CVT Officer’s Certificate under Section 3.2, Section 3.3 or Section 3.4, as applicable, that includes any Overpayment Amounts, the Parties’ Primary Contacts will discuss the amount of such Overpayment Amounts and attempt to agree in writing on (i) the portion of the amount deposited by Astellas into the Joint Concentration Account that correctly represents the portion, if any, of the payment deposited by Astellas into the Joint Concentration Account that is an overpayment with respect to the Regadenoson Royalty or the Related Regadenoson Payments, and the amount thereof (any such agreed upon amount being referred to herein as the “Agreed-On Overpayment Amount”).

(b) To the extent the Parties’ Primary Contacts are unable to agree on the correct amount for any Overpayment Amount (any such disputed amounts being referred to as the “Disputed Overpayment Amounts”), within [****] following delivery of the applicable Royalty Report or CVT Officer’s Certificate under Section 3.2, Section 3.3

or Section 3.4, as applicable, each Party shall designate an executive officer to discuss the matter with an executive officer of the other Party and attempt to reach agreement in writing on the Agreed-On Overpayment Amount within [****] following the end of the prior [****] period (and, if they agree upon the same during such period, such amount shall no longer be a Disputed Overpayment Amount but shall become an Agreed-On Overpayment Amount).

(c) With respect to the amount of any Agreed-On Overpayment Amount deposited into the Joint Concentration Account, the Parties agree that, subject to TPG-Axon’s rights with respect to Account Instructions during a CVT Event of Default as set forth in Section 3.1, at CVT’s election, the agreed upon Final Instructions shall require JPMorgan either (i) to transfer the full amount of such Overpayment Amount from the Joint Concentration Account to an account designated by Astellas to CVT, or (ii) to retain such Overpayment Amount in the Joint Concentration Account and distribute it in accordance with Section 3.1(a) as if it were the Regadenoson Royalty or a Related Regadenoson Payment and had been held in the Joint Concentration Account until the expiration of the applicable Calendar Quarter, in which case the Parties shall each credit the portion of such Overpayment Amount they each so receive against the portion of future Regadenoson Royalties and Related Regadenoson Payments that will become due to each Party pursuant to this Agreement in connection with future payments by Astellas of Regadenoson Royalties under the Astellas Agreement.

(d) In the event Disputed Overpayment Amounts exist following the expiration of the applicable time periods utilized by the Parties under Sections 3.10(a) and (b), each Party is free to pursue a resolution of such dispute with the other Party, along with any related matters, in the judicial system (without having to comply with the dispute resolution procedures set forth in Section 9.2) or to otherwise exercise any right or remedy such Party may have against the other Party pursuant to this Agreement.

3.11 CVT’s Record Keeping; TPG-Axon’s Audit Rights.

(a) Records. CVT and its Affiliates shall, consistent with GAAP and their respective internal financial control and reporting practices and procedures, keep and maintain for a period of [****] years from the end of the applicable Calendar Year (except as otherwise provided herein) accounts and records of all reports and data received by CVT from Astellas reasonably required to verify and calculate the portion of the Regadenoson Royalty and the Related Regadenoson Payments to which TPG-Axon is entitled under this Agreement.

(b) Audit of Astellas. CVT agrees that it shall, at the written request of TPG-Axon and at TPG-Axon’s expense (if not paid for by Astellas under the Astellas Agreement), promptly exercise its rights under Section 6.1 of the Astellas Agreement to conduct an audit of Astellas with respect to payments to CVT of the Regadenoson Royalty and Related Regadenoson Payments (an “Audit”). No more than one Audit may be conducted under this Section 3.11 in any Calendar Year, whether initiated by CVT or at TPG-Axon’s request as set forth in this Section 3.11.

At any time that CVT wishes to exercise CVT’s rights to an Audit (other than pursuant to a request by TPG-Axon), CVT shall give TPG-Axon written notice (an “Audit Notice”) of its desire so to do. Within [****] of receipt of an Audit Notice, TPG-Axon shall provide CVT with written notice of its election to participate in the design of the Audit, and CVT and TPG-Axon shall share equally in the costs of such Audit. In the event that TPG-Axon does not respond to an Audit Notice within such [****] period or advises CVT that it does not desire to participate in the design of the Audit, such Audit shall be at CVT’s sole expense (if not paid for by Astellas under the Astellas Agreement).

All Audits will be conducted by CVT using any nationally recognized independent public accounting firm agreed to between CVT and TPG-Axon, and in accordance with the requirements of the Astellas Agreement. To the extent not prohibited by obligations of confidentiality between CVT and Astellas contained in the Astellas Agreement, TPG-Axon shall receive a copy of the results of such Audit (i.e., the actual amount of Regadenoson Royalty and Related Regadenoson Payments during the Calendar Year in question, and the details of any discrepancies between the Regadenoson Royalty and Related Regadenoson Payments that were paid to TPG-Axon and the Regadenoson Royalty and Related Regadenoson Payments that should have been paid). To the extent delivery of the results of any Audit is prohibited by obligations of confidentiality between CVT and Astellas contained in the Astellas Agreement, then, within [****] of CVT’s receipt of the results of such Audit, CVT shall deliver to TPG-Axon a CVT Officer’s Certificate, dated the date of delivery, certifying (i) that the results of such Audit indicate that there is no discrepancy between the Regadenoson Royalty and Related Regadenoson Payments that were paid to TPG-Axon and the Regadenoson Royalty and Related Regadenoson Payments that should have been paid to TPG-Axon for the Calendar Year in question, or (ii) in the event any such discrepancy exists, that there is a discrepancy. If an Audit indicates that any Regadenoson Royalty or Related Regadenoson Payments that were paid to TPG-Axon during any Calendar Year in question were less than the Regadenoson Royalty or Related Regadenoson Payments that should have been paid to TPG-Axon for such Calendar Year (“Audit Shortfall”), CVT will [****].

Notwithstanding the foregoing, in an abundance of caution to address the possibility that, notwithstanding the intention and expectation of the Parties that the transactions hereunder be a true sale for all purposes, the transactions set forth in this Agreement are determined in a judicial, administrative or other proceeding to be a loan or other financial accommodation instead of a true sale, effective as of the Closing Date, CVT does hereby grant to TPG-Axon a continuing security interest of first priority in all of CVT’s right, title and interest in, to and under the Assigned Rights, whether now or hereafter existing, and any and all proceeds thereof, as security for the prompt and complete payment and performance of all of CVT’s obligations now or hereafter existing under this Agreement and the other Transaction Documents relating directly or indirectly to the Assigned Rights.

(b) Security Interest in Collateral. Effective as of the Closing Date, CVT does hereby grant to TPG-Axon a continuing security interest of first priority in, all of CVT’s right, title and interest in, to and under the Collateral, whether now or hereafter existing,

(ii)

CVT shall provide written notice to TPG-Axon of any [****] the Astellas Agreement or otherwise for any Licensed Patent in the Territory within [****] of any such filing; and

(A)

To modify, in its sole discretion, the Intellectual Property Security Agreement without first obtaining CVT’s approval of or signature to such modification by amending Exhibit B thereof to include reference to any right, title or interest in any Licensed Patents in the Territory acquired by CVT after the date of this Agreement or to delete any reference to any right, title or interest in any Licensed Patents in the Territory in which CVT no longer has or claims any right, title or interest; and

(B)

To file, in its sole discretion, one or more financing or continuation statements and amendments thereto, or other notice filings or notations in appropriate filing offices, relative to any of the Intellectual Property Collateral, with prior notice to CVT, with all appropriate jurisdictions, as TPG-Axon deems appropriate, in order to further perfect or protect TPG-Axon’s interest in the Intellectual Property Collateral.

(c) Security Agreement; Filings. This Agreement shall constitute a security agreement for purposes of the Code in all relevant jurisdictions. In furtherance of the foregoing, CVT hereby authorizes TPG-Axon to file one or more financing statements (or similar documents) in all relevant jurisdictions with respect to the Collateral and the Assigned Rights to evidence the granting of the security interest described in Section 6.7(b) and the precautionary security interest described in Section 6.7(a), provided that TPG-Axon shall provide CVT with a reasonable opportunity to review any such financing statements (or similar documents) prior to filing. For greater certainty, TPG-Axon shall not file this Agreement in connection with the filing of any such financing statements (or similar documents).

(d) Effectiveness of Security Interests. The security interests granted pursuant to the foregoing Section 6.7(a) and Section 6.7(b) shall remain in full force and effect and continue to be effective should any petition be filed by or against CVT for liquidation or reorganization, should CVT become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of CVT’s property and assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the obligations secured thereby, or any part thereof, are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by TPG-Axon, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, such obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

6.8 Investigations. Any investigation or other examination that may have been made or may be made at any time by or on behalf of the Party to whom covenants and obligations are made shall not limit, diminish or in any way affect the covenants and obligations made to such Party or the right of such Party to indemnification, reimbursement or any other remedy based on the covenants and obligations made to it by the other Party. Each Party may rely on the covenants and obligations provided to it in this Agreement by the other Party irrespective of any information obtained by it by any investigation, examination or otherwise.

Any representation or warranty made by CVT under this Agreement and any other Transaction Document proves to have been untrue or incorrect in any respect when made (without giving effect to materiality qualifiers), except to the extent such untruth or inaccuracy, considered collectively with all other such untruths or inaccuracies, would not reasonably be expected to result in a Material Adverse Effect; or CVT Breaches in any material respect any agreement, covenant or obligation that is unqualified as to its performance or satisfaction by materiality or Material Adverse Effect qualifiers, or CVT otherwise Breaches any agreement, covenant or obligation that is qualified as to its performance or satisfaction by materiality or Material Adverse Effect qualifiers, in each case (i) in this Agreement (other than with respect to the matters for which CVT makes direct indemnity payments to TPG-Axon pursuant to Section 3.5(b), 3.5(c) or Section 3.5(d)(iii)) or the Intellectual Property Security Agreement and does not cure such Breach within [****] after written notice of such Breach from TPG-Axon, or (ii) in the Deposit Agreement and does not cure such Breach within [****] after written notice of such Breach from TPG-Axon;

(e) Loss of Valid, Perfected Security Interest. Any security interest purported to be created by this Agreement or any other Transaction Document shall cease to create, or shall be asserted by CVT not to create, a valid, perfected, first priority security interest in the Collateral covered thereby, except to the extent that any such loss of perfection or priority results from the failure of TPG-Axon to make related filings or to continue previously filed financing statements and other documents prior to the expiration thereof or to maintain the Joint Concentration Account in effect.

TPG-Axon provides a notice of termination of the Deposit Agreement or otherwise terminates the Deposit Agreement without CVT’s prior written agreement to or approval of such notice or such termination.

7.4 Remedies for Events of Default.

(a) Default by CVT. If a CVT Event of Default occurs, then TPG-Axon may immediately suspend its obligation to make the Ten Million Dollar ($10,000,000) payment as required under Section 2.1(b)(ii) (if not already satisfied) until CVT cures such CVT Event of Default but TPG-Axon shall continue to be entitled to all of its rights under this Agreement including the TPG-Axon Royalty Interest and the other Assigned Rights [****].

(b) Default by TPG-Axon. If a TPG-Axon Event of Default described in Section 7.3(a) occurs, then CVT may terminate this Agreement on [****] written notice to TPG-Axon, unless TPG-Axon cures such Breach within such [****] period, and if CVT so terminates the Agreement, then as of such date of termination, TPG-Axon shall have no further obligation to provide the Ten Million Dollar ($10,000,000) payment as required under Section 2.1(b)(ii) and shall have no further right whatsoever to receive the TPG-Axon Royalty Interest. If any TPG-Axon Event of Default under Section 7.3 (other than under Section 7.3(a)) occurs, then CVT shall continue to be entitled to all of its rights under this Agreement [****].

(c) Attorney-in-Fact. Subject to the next sentence, CVT hereby irrevocably constitutes and appoints TPG-Axon, and any officer or agent of TPG-Axon, with full power of substitution, as its true and lawful attorney-in-fact with full, irrevocable power and authority in the place and stead of CVT and in the name of CVT or in its own name, from time to time at TPG-Axon’s discretion, for the purpose of exercising the rights and remedies of a secured creditor under the Code, including without limitation, to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable to effect the foregoing. TPG-Axon agrees that, except upon the occurrence and during the continuation of a CVT Event of Default, it shall not exercise the foregoing power of attorney. CVT hereby ratifies, to the extent permitted by law, all that said attorney shall lawfully do or cause to be done by virtue hereof. The power of attorney granted pursuant to this Section 7.4(c) is a power coupled with an interest and shall be irrevocable until the prompt and complete payment and performance of all of CVT’s obligations now or hereafter existing under this Agreement and the other Transaction Documents.

(d) Fees and Expenses. CVT agrees to pay [****] in connection with the [****].

7.5 Not Exclusive. The remedies set forth in Section 7.4 are not the Parties’ exclusive remedies for a CVT Event of Default (as to TPG-Axon) or a TPG-Axon Event of Default (as to CVT), but are in addition to any remedies available to such Party at law or in equity for such event including all rights and remedies under this Agreement and

the other Transaction Documents and, in the case of TPG-Axon, of a secured party under the Code. In the event of a CVT Event of Default (as to TPG-Axon) or a TPG-Axon Event of Default (as to CVT), the Parties acknowledge and agree that each Party may pursue any of such rights or remedies at any time in its sole discretion. All of TPG-Axon’s rights and remedies with respect to the Collateral shall be cumulative.

(c) the negligence, recklessness, intentional wrongful acts or omissions related to this Agreement or the other Transaction Documents of CVT or its Affiliates or any of their respective directors, employees or agents (excluding, for clarity, Astellas and its Affiliates and sublicensees, and any of their respective directors, employees or agents);

provided, that Damages arising from or resulting under the foregoing clause (b) or (h) (to the extent related to (b)) are not subject to indemnification by TPG-Axon under Section 8.3.

8.3 Indemnification by TPG-Axon. TPG-Axon shall hold harmless and indemnify the CVT Indemnitees from and against, and shall compensate and reimburse each of the CVT Indemnitees for, any Damages that are suffered or incurred by any of the CVT Indemnitees or to which any of the CVT Indemnitees may otherwise become subject at any time (regardless of whether or not such Damages relate to any Third Person Claim) to the extent such Damages arise from or result from any of the following:

(a) any material Breach by TPG-Axon of a representation or warranty of TPG-Axon contained in this Agreement or any of the other Transaction Documents or any certificates or other documents delivered pursuant to this Agreement or the material Breach by TPG-Axon of any covenant, condition, agreement, or obligation of TPG-Axon contained in this Agreement or any of the other Transaction Documents or any certificates or other documents delivered pursuant to this Agreement;

provided, that Damages arising from or resulting under the foregoing clause (a) or (c) (to the extent related to (a)) are not subject to indemnification by CVT under Section 8.2.

8.4 Indemnification Procedures.

(a) In the event a Party becomes aware of a claim by a Third Person (including any Proceeding commenced or threatened to be commenced by any Third Person) (a “Third Person Claim”) that such Party reasonably believes may result in a demand for indemnification pursuant to Sections 8.2 or 8.3, as applicable, such Party shall promptly and in good faith notify the other Party in writing of such claim. For purposes of this Section 8.4(a), the Party responsible for giving any such notice (a “Claim Notice”) shall be deemed to be the “Notifying Party,” and the Party receiving the Claim Notice shall be deemed to be the “Notified Party.” If the contents and delivery of a Claim Notice satisfy the content and delivery requirements of an Indemnification Demand pursuant to Section 8.4(b), then such Claim Notice shall also be deemed an Indemnification Demand. The Claim Notice shall be accompanied by reasonable supporting documentation submitted by the Third Person making such Third Person Claim (to the extent then in the possession of the Notifying Party) and shall describe in reasonable detail (to the extent known by the Notifying Party) the facts constituting the basis for such Third Person Claim and the amount of claimed Damages resulting from such Third Person Claim; provided, however, that no delay or failure on the part of the Notifying Party in delivering a Claim Notice shall relieve the Notified Party from any Liability hereunder except to the extent of any Damages caused by or arising out of such delay or failure. Within [****] after receipt of any Claim Notice, the Notified Party may, upon written notice thereof to the Notifying Party, assume control of the defense of the claim referred to therein at the Notified Party’s sole cost and expense with counsel reasonably satisfactory to the Notifying Party. If the Notified Party does not so assume control of the defense of such claim, the Notifying Party shall control the defense of such claim, and the reasonable fees and expenses of counsel to the Notifying Party shall be considered “Damages” for purposes of this Agreement. The Party not controlling the defense of any claim (the “Non-controlling Party”) may participate therein at its own expense; provided, however, that if the Notified Party assumes control of the defense of such claim and the Notified Party and the Notifying Party have materially conflicting interests or different defenses available with respect to such claim which cause the Notifying Party to hire its own separate counsel with respect to such Proceeding, the reasonable fees and expenses of counsel to the Notifying Party shall be considered “Damages” for purposes of this Agreement. The Party controlling the

defense of such claim (the “Controlling Party”) shall keep the Non-controlling Party advised of the status of such claim and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party upon the Controlling Party’s reasonable request with such information as it may have with respect to such claim (including copies of any summons, complaint or other pleading which may have been served on such Party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) (as Confidential Information subject to Article 4 of this Agreement) and shall otherwise cooperate with and assist the Controlling Party in the defense of such claim. Neither the Notified Party nor the Notifying Party shall agree to any settlement of, or the entry of any judgment arising from, any such claim without the prior written consent of the other of such Parties, which shall not be unreasonably withheld or delayed; provided, however, that the consent of the Notifying Party shall not be required with respect to any such settlement or judgment if the Notified Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Notifying Party from further Liability and has no other adverse effect on the Notifying Party.

(b) In order to seek indemnification under this Article 8, a Person entitled to indemnification under Section 8.2, or Section 8.3 (an “Indemnified Party”) shall deliver, in good faith, a written demand (an “Indemnification Demand”) to TPG-Axon (in the case of Indemnification Demands from any CVT Indemnitee) or CVT (in the case of Indemnification Demands from any TPG-Axon Indemnitee) which contains (i) a description and the amount (the “Asserted Damages Amount”) of any Damages incurred or reasonably expected to be incurred by the Indemnified Party, (ii) a statement that the Indemnified Party is entitled to indemnification under this Article 8 for such Damages and a reasonable explanation of the basis therefor, and (iii) a demand for payment in the amount of such Damages. For all purposes of this Section 8.4(b), CVT shall be entitled to deliver Indemnification Demands to TPG-Axon on behalf of the CVT Indemnitees, and TPG-Axon shall be entitled to deliver Indemnification Demands to CVT on behalf of the TPG-Axon Indemnitees.

(c) Within [****] after delivery of an Indemnification Demand to TPG-Axon or CVT, as applicable, such Party shall deliver to the other of such Parties a written response (the “Response”) in which the Party providing the Response shall: (i) agree that the Indemnified Party is entitled to receive all of the Asserted Damages Amount; (ii) agree that the Indemnified Party is entitled to receive part, but not all, of the Asserted Damages Amount (such portion, the “Agreed Portion”); or (iii) dispute that the Indemnified Party is entitled to receive any of the Asserted Damages Amount.

(d) In the event that the Party providing a Response pursuant to Section 8.4(c) shall (i) dispute that the Indemnified Party is entitled to receive any of the Asserted Damages Amount, or (ii) agree that the Indemnified Party is entitled to only the

Agreed Portion of the Asserted Damages Amount, TPG-Axon and CVT shall attempt in good faith to agree upon the rights of the respective Parties with respect to each of the indemnification claims that comprise the Asserted Damages Amount (or the portion of the Asserted Damages Amount not comprising the Agreed Portion). If TPG-Axon and CVT should so agree, a memorandum setting forth such agreement shall be prepared and signed by both such Parties. If no such agreement can be reached after good faith negotiation within [****] after delivery of a Response, the Parties shall thereafter follow the dispute resolutions procedures set forth in Section 9.2 with respect to such dispute.

8.5 Period for Certain Indemnification Claims. No claim for indemnification hereunder for Breach of any representations or warranties contained in this Agreement may be made after the expiration of the survival period applicable to such representation or warranty, as provided in Section 8.1 of this Agreement; provided that any written claim for Breach thereof made prior to such expiration date and delivered to the Party against whom such indemnification is sought shall survive thereafter with respect to such claim.

8.6 Exclusive Remedy. Following the Closing Date, subject to the immediately succeeding sentence and except as set forth in Section 7.4, Section 7.5 or Section 9.3 of this Agreement, the indemnification afforded by this Article 8 shall be the sole and exclusive remedy for any and all Damages sustained or incurred by a Party in connection with the transactions contemplated by the Transaction Documents, including with respect to any material Breach of any representation, warranty or certification made by the other Party in any of the Transaction Documents or certificates or other documents given by the other Party in writing pursuant hereto or thereto or any material Breach under any covenant or agreement by the other Party pursuant to any Transaction Document or certificate or other document given by the other Party in writing pursuant hereto or thereto. Notwithstanding the foregoing, the limitations set forth in this Section 8.6 shall not apply to a Party’s claim for indemnification hereunder in the case of actual fraud, intentional misrepresentation or intentional wrongful acts. In addition, it is understood and agreed among the Parties that, notwithstanding this Section 8.6, each Party may exercise any remedies available to it in the event of a CVT Event of Default (as to TPG-Axon) or a TPG-Axon Event of Default (as to CVT) at law or in equity for such event, including as to TPG-Axon all rights and remedies of a secured party under the Code.

8.7 Limitations. Notwithstanding anything herein to the contrary, but subject to the remainder of this Section 8.7 and each Party’s right to exercise any remedies available to it in the event of a CVT Event of Default (as to TPG-Axon) or a TPG-Axon Event of Default (as to CVT) at law or in equity for such event, including all rights and remedies, as to TPG-Axon, of a secured party under the Code, in no event shall any Party or any Indemnitee of such Party be liable for any indirect, incidental, special or consequential, punitive or exemplary damages, including loss of profits, whether in contract or tort, regardless of whether the other Party shall be advised, shall have

reason to know, or in fact shall know of the possibility of such damages suffered or incurred by such other Party or any Indemnified Party in connection with this Agreement, except to the extent any such Damages are actually paid to a Third Person in connection with Section 8.4(a) of this Agreement. Notwithstanding the foregoing, the limitations set forth in this Section 8.7 shall not apply to a Party’s claim for indemnification hereunder in the case of actual fraud, intentional misrepresentation or intentional wrongful acts. In addition, the Parties acknowledge and agree that (a) TPG-Axon’s Damages, if any, for any indemnifiable events under this Agreement or in the event of any CVT Event of Default will typically include Damages for Regadenoson Royalty payments and Related Regadenoson Payments that TPG-Axon was entitled to receive pursuant to its ownership of the TPG-Axon Royalty Interest and other Assigned Rights but did not receive timely or at all due to such indemnifiable event or CVT Event of Default and (b) TPG-Axon shall be entitled to make indemnification claims for all such missing or delayed Regadenoson Royalty payments and Related Regadenoson Payments that TPG-Axon was entitled to receive pursuant to its ownership of the TPG-Axon Royalty Interest and other Assigned Rights as Damages hereunder (which claims shall be reviewed and assessed by the Parties in accordance with the procedures set forth in this Article 8), and such missing or delayed Regadenoson Royalty payments and Related Regadenoson Payments that TPG-Axon was entitled to receive pursuant to its ownership of the TPG-Axon Royalty Interest and other Assigned Rights shall not be deemed indirect, incidental, special or consequential, punitive or exemplary damages, or lost profits, for any purpose of this Agreement. Additionally, notwithstanding the foregoing, in the event of any Breach or failure in performance of any covenant or agreement contained in this Agreement, the non-Breaching Party shall be entitled to seek specific performance, injunctive or other equitable relief as set forth in Section 9.3 of this Agreement. For the avoidance of doubt, neither Party shall have any right to terminate this Agreement or any other Transaction Document as a result of any Breach by the other Party hereof or thereof (except as set forth in Section 7.4), but instead shall have (x) in the case of TPG-Axon if such Breach constitutes a CVT Event of Default, the right to exercise any remedies available to it in the event of a CVT Event of Default at law or in equity for such event, including all rights and remedies of a secured party under the Code, (y) in the case of CVT if such Breach constitutes a TPG-Axon Event of Default, the right to exercise any remedies available to it in the event of a TPG-Axon Event of Default at law or in equity for such event, and (z) otherwise in the case of TPG-Axon and CVT the right to seek indemnification under this Article 8 and such specific performance.

ARTICLE 9

MISCELLANEOUS

9.1 Governing Law. This Agreement shall be governed by and construed, interpreted and enforced in accordance with the laws of the State of New York, as applied to agreements executed and performed entirely in New York, without giving

effect to the principles of conflicts of law thereof other than Section 5-1401 of the General Obligations Law of the State of New York. Each Party agrees that any Proceeding against such Party brought by the other Party, arising out of or based upon this Agreement or the transactions contemplated hereby, may be instituted in any state or Federal court in the City of New York, New York or in the City of San Francisco, California, and waives any objection that such Party may now or hereafter have to the laying of venue of any such Proceeding, and irrevocably submits to the non-exclusive jurisdiction of any such courts in any such Proceeding.

9.2 Dispute Resolution. Prior to the initiation of any litigation between the Parties (except for their rights to pursue equitable remedies under Section 9.3 below), any dispute, controversy or claim arising under, out of or in connection with this Agreement, including any subsequent amendments, or the validity, enforceability, construction, performance or Breach hereof shall be first addressed between the Parties’ Primary Contacts who will attempt in good faith to reach a mutually acceptable resolution to it. However, if a Party believes that such discussions are not proving satisfactory, it may appoint an executive officer to discuss, and attempt to resolve, the dispute with the other Party and send written notice to the other Party asking such Party to also appoint an executive officer to discuss and attempt resolve the dispute (the “Dispute Notice”). In such case, these two executive officers (or their designees) shall, by phone or in-person, discuss the dispute in good faith within [****] after the Dispute Notice. If, within [****] after the Dispute Notice, the two executive officers (or their designees) have not reached a mutually acceptable resolution to the dispute, then the Parties are free to pursue a resolution of the dispute in the judicial system. Subject to the foregoing, in connection with any resolution of any dispute under this Agreement in the judicial system, the prevailing Party in the applicable legal action or other legal proceeding shall be entitled to recover from the other Party all fees, costs and expenses incurred with respect thereto, including reasonable attorneys’ fees, costs and expenses.

9.3 Equitable Relief. Each of the Parties hereto acknowledges that the other Party may have no adequate remedy at law if it fails to perform any of its obligations under this Agreement in any material respect. In such event, the Parties agree that, in addition to any other rights the Parties may have (whether at law or in equity), in the event of any material Breach or threatened material Breach by any Party of any covenant, obligation or other provision set forth in this Agreement, the other Party shall be entitled (in addition to any other remedy that may be available to it) to (a) a decree or other of specific performance or mandamus to enforce the observance and performance of such covenant, obligation or other provision, and (b) an injunction restraining such material Breach or threatened material Breach. In addition, each Party may pursue such equitable remedies without going through the informal dispute resolution process in Section 9.2 in order to preserve the status quo or prevent irreparable harm.

9.4 Expenses. Each Party shall be responsible for and bear all of its own costs and expenses (including any legal fees, any accountants’ fees and any brokers’ or finders’ or investment banking fees or any prior commitment in respect thereof) with regard to the negotiation and consummation of the transactions contemplated by this Agreement.

[****] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule d24b-2 of the Securities Exchange Act of 1934, as amended. Confidential treatment has been requested with respect to the omitted portions.

9.5 Relationship of the Parties. The Parties acknowledge and agree that the relationship between TPG-Axon and CVT under this Agreement is intended to be that of buyer and seller, and nothing in this Agreement is intended to be construed so as to suggest that either Party (except as expressly set forth herein) is obligated to provide, directly or indirectly, any advice, consultations or other services to the other Party. The Parties further acknowledge and agree that TPG-Axon is purchasing the Assigned Rights solely in its capacity as an investor and is not acting as a lender or provider of any financial accommodation to CVT under this Agreement or otherwise. Each Party is an independent contractor relative to the other Party under this Agreement, and this Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of co-partners or joint venturers between the Parties. CVT shall have no responsibility for the hiring, termination or compensation of TPG-Axon’s employees or for any employee benefits for such employees and TPG-Axon shall have no responsibility for the hiring, termination or compensation of CVT’s employees or for any employee benefits of such employees. No employee or representative of a Party shall have any authority to create or impose any contractual or other liability on the other Party.

9.6 Successors and Assigns. Neither this Agreement nor any rights or obligations hereunder may be assigned, sold or otherwise disposed of or transferred in whole or in part by either Party, by operation of law or otherwise, without the prior written consent of the other Party, provided, however, that without the prior written consent of the other Party, but subject to the other terms of this Section 9.6:

(a) CVT may assign, sell or otherwise dispose of or transfer this Agreement or its rights or obligations hereunder, in whole or in part, to any of its Affiliates (while such entity remains an Affiliate) if CVT guarantees the performance of this Agreement by such Affiliate and such Affiliate expressly agrees to assume such performance, both guarantee and assumption in a writing in form and substance reasonably satisfactory to TPG-Axon;

(c) At any time after the Payment Obligation End Date, TPG-Axon may assign, sell or otherwise dispose of or transfer this Agreement and its rights and obligations hereunder, in whole but not in part, to any Person (and, in connection with any such assignment, sale or other disposition or transfer, the Parties acknowledge and agree that TPG-Axon shall not retain any obligation to continue to satisfy or perform any obligation that is assigned, sold, or otherwise disposed of or transferred to any other Person);

(d) At any time after the Payment Obligation End Date, TPG-Axon may assign, sell or otherwise dispose of or transfer all or any part of the Assigned Rights (and the related security interest and enforcement rights in the Collateral created under this Agreement and the other Transaction Documents) and any other right to receive payment under this Agreement to any one or more Persons; and

(e) Any Party may assign, sell or otherwise dispose of or transfer this Agreement and its rights or obligations hereunder to: (i) a Person that acquires all or substantially all of its assets to which this Agreement relates or (ii) if such Party is a party to a merger, consolidation, share exchange, business combination or similar transaction and is not the surviving entity, to the surviving or new entity from such transaction.

Any assignment, sale, pledge, contribution or other transfer, in whole or in part, by TPG-Axon of its rights and obligations under this Agreement to any other Person in accordance with the preceding provisions shall require, so long as TPG-Axon is a trust, the approval of the applicable trustee.

Any permitted assignment, sale or other disposition under this Section 9.6 shall only be effective upon the written notification by the applicable Party to the other Party of such assignment, sale or other disposition and the written agreement of the assignee or purchaser (other than an assignee, purchaser or other receiving Person under clause (d) above) to be bound by all the provisions of the Transaction Documents.

Finally, notwithstanding any of the foregoing, (i) without CVT’s prior written consent (which may be given or withheld in CVT’s sole discretion), TPG-Axon may not assign, sell or otherwise dispose of or transfer its rights or obligations under this Agreement, in whole or in part, to [****] and (ii) without TPG-Axon’s prior written consent (which may be given or withheld in TPG-Axon’s sole discretion), CVT may not assign, sell or otherwise dispose of or transfer, in whole or in part, to [****].

This Agreement shall be binding upon, and subject to the terms of the foregoing sentences, inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns. Any assignment or attempted assignment not in accordance with this Section 9.6 shall be null and void.

or to such other address or addresses as TPG-Axon or CVT may from time to time designate by notice as provided herein. Any such notice shall be deemed given (i)

when actually received when so delivered personally or by overnight courier or (ii) if sent by facsimile transmission on the date sent if such day is a Business Day or the next following Business Day if such day is not a Business Day.

9.8 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction. Nothing in this Agreement shall be interpreted so as to require a Party to violate any Applicable Law.

9.9 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion.

9.10 Entire Agreement. This Agreement (including the Exhibits and Schedules hereto), the Deposit Agreement and the Intellectual Property Security Agreement set forth all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties and supersedes and terminates all prior agreements and understandings between the Parties. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as set forth in this Agreement (including the Exhibits and Schedules hereto), the Deposit Agreement and the Intellectual Property Security Agreement. The Parties acknowledge and agree that the ownership of the TPG-Axon Royalty Interest and the rights of TPG-Axon with respect thereto and otherwise with respect to the Assigned Rights and as set forth in this Agreement are enshrined in this Agreement and the other Transaction Documents.

9.11 Third Person Beneficiaries. Except with regard to TPG-Axon Indemnitees and the CVT Indemnitees under Article 8, all rights, benefits and remedies under this Agreement are solely intended for the benefit of the Parties (including their permitted successors and assigns), and no Third Person (except TPG-Axon Indemnitees and CVT Indemnitees with regard to their rights, benefits and remedies under Article 8 of this Agreement, and except for the Parties’ permitted successors and assigns) shall have any rights whatsoever to (i) enforce any obligation contained in this Agreement, (ii) seek a benefit or remedy for any Breach of this Agreement, or (iii) take any other action relating to this Agreement under any legal theory, including actions in contract, tort (including negligence, gross negligence and strict liability), or as a defense, setoff or counterclaim to any action or claim brought or made by the Parties (or any of their permitted successors and assigns).

9.12 Interpretation. When a reference is made in this Agreement to Articles, Sections, Schedules, or Exhibits, such reference shall be to an Article, Section, Schedule, or Exhibit to this Agreement unless otherwise indicated. The words “include,” “includes”, and “including” when used herein shall be deemed in each case to be followed by the words “without limitation” and shall not be construed to limit any general statement which it follows to the specific or similar items or matters immediately following it. The headings and captions in this Agreement are for convenience and reference purposes only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement. Unless specified otherwise, all statements of, or references to, monetary amounts in this Agreement are to United States Dollars. Each accounting term used herein that is not specifically defined herein shall have the meaning given to it under GAAP, but only to the extent consistent with its usage and the other definitions in this Agreement. Provisions that require that a Party or the Parties “agree,” “consent”, or “approve” or the like shall require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes or otherwise. Words of any gender include the other gender and words using the singular or plural number also include the plural or singular number, respectively. Neither Party hereto shall be or be deemed to be the drafter of this Agreement for the purposes of construing this Agreement against one Party or the other.

9.13 Amendments. This Agreement may be amended or supplemented only by a written agreement signed by an authorized officer of both TPG-Axon and CVT (including, for so long as TPG-Axon is a trust, its trustee).

9.14 Counterparts and Facsimile Execution. This Agreement may be executed in two or more counterparts, each of which shall be an original, but all of which together shall constitute one and the same instrument. To evidence the fact that it has executed this Agreement, a Party may send a copy of its executed counterpart to the other Party by facsimile transmission. That Party shall be deemed to have executed this Agreement on the date it sent such facsimile transmission. In such event, such Party shall forthwith deliver to the other Party the counterpart of this Agreement executed by such Party.

9.15 Survival. The rights and obligations of the Parties under the provisions of Articles 1, 4 (for the period set forth therein), 8 (including, with respect to representations and warranties and post-Closing covenants, to the extent set forth in Section 8.1) and 9 and Sections 2.1(d), 3.11, 5.3, 5.4 and 6.8 survive the termination of this Agreement or expiration of this Agreement. Except as specifically provided to the contrary in this Agreement, termination of this Agreement or expiration of the Agreement will be without prejudice to any rights that have accrued to the benefit of a Party prior to such termination or expiration and will not relieve a Party of any

obligations accrued by it hereunder prior to such termination or expiration. Further, except as specifically provided to the contrary in this Section 9.15 or other provision hereof that by its express terms survives the termination of this Agreement or expiration of this Agreement, all rights and obligations of the Parties under all other provisions in this Agreement shall terminate upon termination of this Agreement or expiration of this Agreement for any reason.

9.16 Further Assurances. Each of the Parties hereto shall execute and deliver such additional documents, certificates and instruments, and perform such additional acts, as may be reasonably requested and necessary or appropriate to carry out the purposes and intent and all of the provisions of this Agreement and the other Transaction Documents and to consummate all of the transactions contemplated by this Agreement and the other Transaction Documents.

9.17 Remedies. The rights and remedies of the Parties under this Agreement and the other Transaction Documents are cumulative and not alternative. Neither the failure nor any delay by any Party in exercising and right, power or privilege under this Agreement or any other Transaction Document will operate as a waiver of such right, power or privilege, and no single or partial exercise of such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege.

IN WITNESS WHEREOF, the Parties have executed this Agreement in duplicate originals by their duly authorized representatives as of the date first set forth above.
