If an Acquiror engages in Competing Activities during the Term, as from the closing of such transaction, Sutro will (A) grant Sutro’s CMO that Manufactures CFE a non-exclusive, non-transferrable license under the CFE Technology to manufacture and supply CFE to Ipsen during the Term solely for Ipsen’s production of Licensed Compound to be incorporated into a Licensed Product, provided that such license would not permit the CMO to disclose any CFE Technology to Ipsen and further provided that such CMO agree to the terms of a license on terms substantially equivalent to those in the then existing agreement between Sutro and the CMO and subject

to the terms set forth in Schedule 2.6(a) as if such CMO were Ipsen, (B) notify such CMO of this license in a letter, (C) facilitate introductions between the CMO and Ipsen to enable Ipsen to negotiate with the CMO regarding a relevant manufacturing agreement with such CMO, and (D) use Commercially Reasonable Efforts to request that such CMO share with Ipsen an unredacted copy of the contract between the CMO and Sutro and to reasonably cooperate with Ipsen in such negotiation. Sutro shall use Commercially Reasonable Efforts to promptly amend its existing agreement (or enter into a new agreement) with its CMO that Manufactures CFE to incorporate the terms set forth in Schedule 2.6(a) as if such CMO were Ipsen.

(d)

Backup Supplier for CFE. Upon Ipsen’s request, Sutro shall select a Third Party CDMO for the Manufacturing of CFE (“Backup CFE Manufacturer”) that is reasonably acceptable to Ipsen to Manufacture CFE for supply to Ipsen and have such Backup CFE Manufacturer qualified, equipped and validated in accordance with cGMP and Applicable Laws; provided that Ipsen’s request to Sutro includes a non-binding delivery forecast of the quantity of CFE Ipsen reasonably anticipates to be procured from such Backup CFE Manufacturer for use in the Manufacture of Licensed Compound to be incorporated into Licensed Product (“Ipsen Backup CFE Forecast”). Within thirty [*] of its receipt of Ipsen’s request (including the Ipsen Backup CFE Forecast), Sutro will provide a delivery forecast of the quantity of CFE Sutro reasonably anticipates to be procured from such Backup CFE Manufacturer for uses other than Manufacture of Licensed Compound to be incorporated into Licensed Product (“Sutro Backup CFE Forecast”). The Ipsen Backup CFE Forecast and Sutro Backup CFE Forecast will each include a monthly forecast for at least the [*] (such period, the “[*] Pro-Rata Period”). Sutro shall be responsible for obtaining, with Ipsen’s support as requested by Sutro, any necessary Regulatory Approvals for the manufacture of CFE by the Backup CFE Manufacturer by the relevant Regulatory Authorities in the country where the Backup CFE Manufacturer is located, the United States, the Major European Markets and any other countries mutually agreed between the Parties. The costs and expenses incurred directly or indirectly by Sutro or its Affiliates associated with the engagement of the Backup CFE Manufacturer, including the costs for technology transfer of the Manufacturing process to such Backup CFE Manufacturer, any capital expenditures or non-recurring engineering costs incurred by such Backup CFE Manufacturer and costs associated with obtaining necessary Regulatory Approvals of the Backup CFE Manufacturer in countries as mutually agreed shall be borne by Ipsen in the event the Sutro Backup CFE Forecast does not include any forecasted delivery of CFE during the [*] Pro-Rata Period. Otherwise, in the event the Sutro Backup CFE Forecast includes forecasted delivery of CFE during the [*] Pro-Rata Period, the costs and expenses mentioned in the preceding sentence shall be apportioned between Ipsen and Sutro on a pro-rata basis based on the forecasted quantities of CFEs provided in the Ipsen Backup CFE Forecast and Sutro Backup CFE Forecast during the [*] Pro-Rata Period. For clarity, each Party’s share of such costs and expenses will not be changed by any subsequent changes in either forecast.

5.3

Subcontracting by Sutro.

Sutro may exercise any of its rights, or perform any of its obligations, under this Agreement by subcontracting the exercise or performance of all or any portion of such rights and obligations on Sutro’s behalf by a CMO of Sutro’s choice after Ipsen has been given reasonable opportunity to comment on such choice, provided that the final selection shall be under Sutro’s decision making authority so long as such CMO is an established Third Party CMO of pharmaceutical products that is GMP qualified. Any subcontract granted or entered into by Sutro with a subcontractor as contemplated by this Section that Sutro may have under this Agreement shall not relieve Sutro from any of its obligations under this Agreement. Sutro shall remain liable for the acts and omissions of its subcontractors under this Agreement as if “Sutro” hereunder. If at any time after the Effective Date, Sutro reasonably determines that it will conduct the Manufacturing activities required hereunder that were initially subcontracted to a CMO directly instead of through one or more CMO, such transfer of responsibility to Sutro shall be subject to Ipsen’s express prior consent and approval, which consent shall not be unreasonably withheld if Sutro’s determination is commercially reasonable from the viewpoint of this Agreement as a whole taking into account both Parties’ interests.

5.4

Failure to Supply CFE by Sutro.

(a)

If Sutro is unable to supply Ipsen with the CFE as required under the CFE Supply Agreement (or prior to the execution of such agreements, as required by Ipsen pursuant to Section 5.2(a)), which inability to supply does not qualify as a Supply Failure (“CFE Shortage”), then, Sutro shall promptly notify Ipsen of such CFE Shortage (or anticipated shortage) and unless the Parties otherwise agree in writing, for so long as such CFE Shortage endures, Sutro shall allocate its available CFE as follows: (i) CFE for supply to Ipsen hereunder on the one hand, and (ii) other uses of Sutro and its Affiliates, on the other hand, in the same proportion as CFE is anticipated to be used between (i) Ipsen and (i) Sutro and its Affiliates pro rata, based on the [*] of the applicable forecast most recently submitted by Ipsen to Sutro, based on the proportion represented by the immediately subsequent [*] of Ipsen’s binding supply orders most recently submitted by Ipsen to Sutro relative to the sum of (i) and (ii). [*]

(b)

If Sutro is unable to supply the CFE to Ipsen as required under the CFE Supply Agreement (or prior to the execution of such agreement, as required by Ipsen pursuant to Section 5.2(a)), and such inability to supply results in Sutro’s failure to fulfill at least [*] of the quantity of firm purchase orders issued by Ipsen in accordance with the CFE Supply Agreement, and such failure continues during a period of [*] calendar months during a rolling [*] calendar period (“Supply Failure”), Ipsen shall have the right to send Sutro a written Supply Failure notice during or within [*] after the end of such Supply Failure period in which Ipsen elects for Sutro to initiate technology transfer of CFE Know-How. As an example, assuming a supply failure in January, February, April, and September through November (inclusive) of the same year, Ipsen will have the right to send the Supply Failure notice after the end of October until [*] after the end of November. For clarity, [*] Within [*] of Sutro’s receipt of Ipsen’s timely Supply Failure notice, the Parties will confer to define selection criteria for a new CMO for Manufacture of CFE. If Sutro does not cure the Supply Failure by fulfilling at least [*] of Ipsen’s firm purchase orders that were not supplied during the Supply Failure period within [*] of Sutro’s receipt of Ipsen’s timely Supply Failure notice (“Initiation of CFE Technology Transfer”), then (1) the definition of Sutro Manufacturing Technology (as defined in Section 5.5(a)) shall further include CFE Know-How (to the extent necessary for Ipsen to Manufacture CFE or the Licensed Product), (2) the technology transfer obligations relating to Sutro Manufacturing Technology as set forth in Section 5.5(a), (b), and (c), shall be expanded to account for the expanded definition, solely as required to for Ipsen to Manufacture or have Manufactured CFE for use in Manufacturing Licensed Compound to be incorporated into Licensed Product hereunder (“Supply Failure CFE Technology Transfer”) and the Parties will use Commercially Reasonable Efforts to promptly complete the Supply Failure CFE Technology Transfer, with each Party bearing its own costs and expenses, notwithstanding the allocation of costs set forth in Section 5.5(b). Notwithstanding any other terms in this Agreement, any obligation to provide or otherwise make available any CFE Technology by or on behalf of Sutro is contingent upon entry into, and any such disclosures would be subject to, a confidentiality agreement(s) between Sutro and Ipsen and between Sutro and any Ipsen CDMO receiving any CFE Know-How, such agreement(s) including confidentiality and non-use restrictions and other safeguards to maintain confidentiality of CFE Know-How, taking into account the trade secret status thereof.

5.5

Manufacturing Transition Activities in Connection with the Licensed Product and Licensed Compound.

To enable Ipsen to assume control and have the sole responsibility for, at Ipsen’s cost, all Manufacturing activities for all Licensed Compound and Licensed Products (excluding the CFE) after the Transition Period, as mentioned in Section 5.1(a):

(a)

Subject to sub-section (d) below and Sections 2.5(e) and 5.4(b), Sutro will make available to Ipsen all the Sutro Know-How, Sutro Manufacturing Know-How (to the extent necessary for Ipsen to Manufacture the Licensed Product) and any other information and documents in Sutro’s possession and Control, as well as tangible Materials, that are necessary to enable Ipsen, its Affiliates, or its designated CMOs to Manufacture the Licensed Compounds (including for the avoidance of doubt,

the Linker-Payload) and Licensed Product for Ipsen’s Development and Commercialization activities, including relevant documents, information, and Materials (standard reference, available batches of active substance, intermediates, and drug product) in Sutro’s possession and Control (“Sutro Manufacturing Technology”). Notwithstanding the foregoing, Sutro Manufacturing Technology shall expressly exclude any and all CFE Technology, except to the extent CFE Know-How is incorporated into the definition of Sutro Manufacturing Technology pursuant to Section 5.4(b) following Initiation of CFE Technology Transfer. Any Materials provided by Sutro in connection with the technology transfer of the Sutro Manufacturing Technology will be granted under license to Ipsen pursuant to Section 2.1 and remain the sole property of Sutro, and Ipsen will (a) use such Sutro Manufacturing Technology only in the fulfillment of obligations or exercise of rights under this Agreement, and (b) not use such Sutro Manufacturing Technology or deliver the same to any Third Party, other than CMOs or permitted Sublicensees used in connection with Manufacturing, without Sutro’s prior written consent, not to be unreasonably withheld, conditioned, or delayed.

(b)

For purposes of the technology transfer of the Sutro Manufacturing Technology, the Parties may enter into a manufacturing technology transfer agreement for the technology transfer to Ipsen of such necessary documents and information and will also provide for reasonable technical assistance and support by Sutro to Ipsen to enable Ipsen to Manufacture or have Manufactured by a CMO engaged by Ipsen (“Manufacturing Technology Transfer Agreement”). Sutro’s or its Affiliate’s reasonable technical assistance and support for such technology transfer of the Sutro Manufacturing Technology to Ipsen shall be invoiced to Ipsen at the FTE Rate (with no mark-up) rather than actual costs and further provided that, for such assistance in support of transfer of the Sutro Manufacturing Technology directed to Manufacturing of the Antibody, Ipsen shall not bear the cost of the [*] spent by Sutro. For clarity, [*]. The Manufacturing Technology Transfer Agreement shall include terms providing Ipsen sufficient rights to use the Sutro Manufacturing Technology, which shall not be inconsistent with the terms and conditions in this Agreement.

(c)

In the event the Sutro Manufacturing Transition Activities were performed by a CMO on behalf of Sutro (including without limitation in connection with the Manufacture of the Linker-Payload, pAMF, Plasmid and CFE Reagents), at Ipsen’s option and upon Ipsen’s request to Sutro, Sutro shall facilitate introductions between the CMO and Ipsen to enable Ipsen to negotiate with the CMO regarding a relevant manufacturing agreement with the CMO. Sutro will use Commercially Reasonable Efforts to request that each such CMO to share with Ipsen an unredacted copy of the contract between the CMO and Sutro and to reasonably cooperate with Ipsen in such negotiation.

(d)

Notwithstanding anything to the contrary:

(i)

with respect to the [*], (1) Ipsen shall select, after having heard and taken into account in good faith the position of and comments made by Sutro, a CMO for Manufacture of the Antibody within [*] of the Effective Date, (2) the JMC will define and approve a technology transfer plan with respect to the Sutro Manufacturing Transition Activities of Sections 5.5(a), (b) and (c) for technology transfer to the selected CMO, and (3) then (after (1) and (2)) Sutro shall initiate such technology transfer promptly after execution of a service agreement between the Parties and the selected CMO which shall be executed no later than [*] months after Ipsen having selected the CMO as per (1) and Sutro shall use Commercially Reasonable Efforts to complete such technology transfer activities no later than [*] month after the initiation of the Phase Ia Trial;

(ii)

with respect to each of the [*], following definition and approval of an applicable written technology transfer plan by the JMC, Sutro shall initiate the Sutro Manufacturing Transition Activities of Section 5.5(a), (b) and (c) upon Ipsen’s request, prior to [*], and shall use Commercially Reasonable Efforts to complete such activities, taking into account the relative complexity of the technology transfer and acknowledging the Parties’ best interest in allowing the effective technology transfer to Ipsen of the Manufacturing of the Licensed Product, and the Parties will use Commercially Reasonable Efforts to perform the Sutro Manufacturing Transition Activities pursuant the technology transfer plan;

(iii)

in case of Supply Failure, following Initiation of CFE Technology Transfer, Sutro shall effect the technology transfer of the Sutro Manufacturing Technology with respect to CFE Know-How as set forth in Sections 5.4, 5.5(a), (b) and (c), regardless of whether the Supply Failure is subsequently remedied following Initiation of CFE Technology Transfer. The Parties will use Commercially Reasonable Efforts to complete such Sutro Manufacturing Transition Activities under this subsection promptly following Initiation of CFE Technology Transfer;

(iv)

the Sutro Manufacturing Transition Activities shall not include the provision or any right to access of the CFE Technology, and Sutro shall have no obligation to deliver or make available to Ipsen (or any of its Affiliates or any Third Party, including any designated CMO) any CFE Technology, unless and until Initiation of CFE Technology Transfer occurs.

5.6

Ipsen’s Manufacturing.

(a)

Ipsen, its Affiliates, its Sublicensees and other Third Parties selected by Ipsen shall be solely responsible, at its sole cost and expense, for Manufacturing activities for all Licensed Compound and all Licensed Products after the completion of Sutro Manufacturing Transition Activities and for the Commercialization of the Licensed Product (except as provided in Section 5.2 with respect to the Manufacture and supply of the CFE).

(b)

In connection with the Manufacturing activities that will be performed by Ipsen, Sutro shall grant Ipsen an exclusive license (except as to the CFE Technology which grant shall be non-exclusive, following Initiation of CFE Technology Transfer) to Manufacture or have Manufactured the Licensed Compound and the Licensed Product in the Field during the Term, within the Territory, by itself or through an Affiliate or Sublicensee, or authorize or license any Third Party, under Sutro Know-How, Sutro Patents and Sutro Manufacturing IP. The Parties acknowledge and agree that when Sutro or its CMO supplies Ipsen with the CFE in accordance with Section 5.2, to allow Ipsen to conduct its Development and Commercialization for the Licensed Product in the Territory in the Field under this Agreement, Ipsen shall not require a license under CFE Technology to use the CFE Technology with such supplied CFE solely for the purpose of Manufacturing the Licensed Compound for incorporation into Licensed Product under the Agreement and as such, such use of the CFE Technology shall not be considered an infringement or an unauthorized use by Ipsen of Sutro’s CFE Technology and that no further license is required from Sutro for such use.

5.7

Quality Technical Agreement.

The Parties will also negotiate and enter into a separate quality technical agreement (“QTA”) within [*] of the Effective Date or otherwise agreed by both Parties. Pursuant to Section 6.6 (CMC and Quality Audit), within [*] of the Effective Date, Sutro shall allow Ipsen to conduct, at Ipsen’s Cost, a GMP quality inspection of the Manufacturing site of Sutro and of each of Sutro’s CMO (solely if, and to the extent, permitted by Sutro’s contracts with its CMOs and subject to Sutro’s Commercially Reasonable Efforts) in which the Licensed Compound (excluding CFE) and the Licensed Product is Manufactured, stored and handled to assess compliance with GMP standard and applicable regulatory requirements; provided that Ipsen shall have no right to audit any information directed to CFE Technology or Manufacture of CFE.

Article 6

To the extent Ipsen receives any written or oral communications from any Regulatory Authority relating to the Licensed Product that may impact CFE, Ipsen shall notify Sutro and provide Sutro with a copy of any and all such written communication received by Ipsen as soon as reasonably practicable, but no later than [*] (or such shorter time as is necessary to comply with the reporting requirements of any applicable Regulatory Authority or under Applicable Laws) as well as if applicable, a summary of such oral communication that Ipsen may have had with the Regulatory Authority relating to the Licensed Product that may impact CFE. Following the Effective Date, Sutro shall not initiate, with respect to any Licensed Product, any meetings or contact with Regulatory Authorities without Ipsen’s prior written consent. To the extent Sutro receives any written or oral communication from any Regulatory Authority relating specifically to the Licensed Product, Sutro shall: (a) refer such Regulatory Authority to Ipsen, and (b) notify Ipsen and provide Ipsen with a copy of any and all written communication received by Sutro as soon as reasonably practicable, but no later than [*] of receipt (or such shorter time as is necessary to comply with the reporting requirements of any applicable Regulatory Authority or under Applicable Laws), as well as if applicable, a summary of such oral communication that Sutro may have had with the Regulatory Authority. At the reasonable request of Ipsen, Sutro shall make available to Ipsen, at Ipsen’s Cost, a qualified representative who shall, together with the representatives of Ipsen, participate in and contribute to meetings directed to an Ipsen application for Regulatory Approval of a Licensed Product, with respect to regulatory matters relating to the Sutro Technology, with FDA until the first Regulatory Approval by the FDA for any Licensed Product or with EMA until the first Regulatory Approval for any Licensed Product by the EMA. Reasonable expenses for the attendance of Sutro’s qualified representative to any such meetings with the Regulatory Authorities will be reimbursed by Ipsen [*]. To the extent Sutro receives any written or oral communication from any Regulatory Authority directly impacting but not relating specifically to the Licensed Product and not directed to CFE, Sutro shall promptly provide Ipsen with a copy of any and all such written communications or a summary of such oral communication that Sutro may have had with the Regulatory Authority, each of the foregoing redacting any CFE Know-How unless the communication is received following Initiation of CFE Technology Transfer.

6.3

Communications with Regulatory Authorities for the CFE. Sutro shall be responsible, and act as the sole point of contact, for communications with Regulatory Authorities in connection with the Development and Manufacturing of the CFE and shall respond to any requests or inquiries from Regulatory Authorities related thereto within the timeframe required for response, if a separate communication specifically related to the CFE is permitted before the relevant Regulatory Authorities. To the extent Ipsen receives any written or oral communications from any Regulatory Authority relating specifically to the CFE or CFE Reagents that are supplied by or on behalf of Sutro for the Licensed Product, Ipsen shall: (a) refer such Regulatory Authority to Sutro, and (b) notify Sutro and provide Sutro with a copy of any and all written communication received by Ipsen as soon as reasonably practicable, but no later than [*] (or such shorter time as is necessary to comply with the reporting requirements of any applicable Regulatory Authority or under Applicable Laws) as well as if applicable, a summary of such oral communication that Ipsen may have had with the Regulatory Authority. Sutro will keep Ipsen informed of and provide Ipsen with a copy of: (a) material correspondence and (b) Regulatory Materials, each of (a) and (b) relating specifically to the CFE (only following Initiation of CFE Technology Transfer) or CFE Reagents that are supplied by Sutro for the Licensed Product, which (a) and (b) are exchanged between Sutro and Regulatory Authorities (or submitted by Sutro before the Regulatory Authorities) that may impact Ipsen’s filing and maintenance of the IND and MAA of the Licensed Products and generally, that may impact the Development, Manufacturing or supply of the Licensed Compound and Licensed Product. Such copies relating specifically to CFE Reagents may be reasonably redacted by Sutro to limit disclosure of the CFE Technology, if Initiation of CFE Technology Transfer has not occurred at the time such copies are provided.

6.4

Ipsen agrees to comply with any and all Applicable Laws that are applicable as of the Effective Date and thereafter during the Term in connection with, and shall be solely responsible for, safety data collection and reporting of Adverse Events in connection with the Licensed Products in the Territory.

6.5

Recalls. Ipsen shall have the sole right to determine whether and how to implement a recall or other market withdrawal (“Recall”) of any Licensed Product. Ipsen shall be responsible for all costs of any Recall for any Licensed Product, including Sutro’s Internal Costs and External Expenses except to the extent such Recall resulted solely from the failure of CFE supplied by Sutro to meet the applicable GMP specifications (“CFE Specification Failure”). Ipsen shall promptly notify Sutro of any threatened or pending action, inspection or communication by any Regulatory Authority specifically regarding the safety or efficacy claims of any Licensed Compound or Licensed Product. Without limiting the foregoing, Ipsen shall promptly notify Sutro if it obtains information indicating that any Licensed Product may be subject to any Recall or corrective action taken by virtue of Applicable Law. To the extent any Recall with respect to the Licensed Product is in part the direct result of CFE, promptly after being notified of a Recall, Sutro will provide Ipsen with such assistance as may be reasonably requested by Ipsen in gathering any information directly related to the CFE as is necessary in the conduct by Ipsen of the Recall. Any costs and expenses incurred by Sutro to the extent the Recall resulted solely from CFE Specification Failure shall be borne by Sutro and if the Recall is in part the result of CFE Specification Failure, then the cost and expenses of the Recall shall be allocated between the Parties in an equitable manner.

6.6

CMC and Quality Audit. Until a period of [*] after the completion of the Manufacturing Transition Activities and during the Term so long as Sutro is providing Ipsen with the CFE as set forth in Section 5.2 and for a period of [*] thereafter, to the extent required for Ipsen to comply with its obligations and responsibilities as IND holder and Marketing Authorization Holder for the Licensed Product, including any of its responsibilities for submission of IND, MAAs and CMC variations to a Regulatory Authority in the Territory, upon Ipsen’s request filed [*] in advance, Sutro shall allow Ipsen, no more than once per calendar year, to conduct an audit and inspection of Sutro’s Manufacturing site and an audit of the Manufacturing site of each of Sutro’s CMOs in which the Licensed Compound (excluding CFE) and the Licensed Product is manufactured, stored, handled or shipped to permit Ipsen as IND and Marketing Authorization Holder to verify Sutro and its CMO’s compliance with all applicable GMP; provided that Ipsen shall have no right to audit any information directed to CFE Technology or Manufacture of CFE (solely if, and to the extent, permitted by Sutro’s contracts with its CMOs and subject to Sutro’s Commercially Reasonable Efforts), during normal business hours, as well as all relevant quality records maintained by Sutro (or its CMO), including relevant quality standard operating procedures, CMC data, documented processes, quality systems and validation procedures within the audited entity’s possession and control to the extent relating to the Manufacturing of the Licensed Compound and Licensed Product, including those generated by the CMO performing such Manufacturing on behalf of Sutro, to assess compliance with GLP, GDP and GMP standards and applicable regulatory requirements. If Sutro desires to similarly inspect the CMO for cGMP purposes, it shall notify Ipsen and the Parties may jointly inspect the CMO, to the extent permitted under the agreement between Sutro and its CMO. Detailed audits processes shall be addressed in the manner specified in the Manufacturing Transition Agreement, CFE Supply Agreement or associated quality agreements. Notwithstanding anything to the contrary, in no event shall Ipsen have access to any CFE Know-How in connection with the activities described in this Section 6.6.

(b)

For the avoidance of doubt, each aforementioned Sales Milestone Payment shall be made only once based on aggregate sales for all Licensed Products, regardless of the number of Licensed Products sold, or the number of Calendar Years in which aggregate Net Sales of all Licensed Products achieve such Sales Milestone Event. [*].

7.5

Royalty Payments for Licensed Products.

(a)

Royalty Rate. As further consideration for Sutro’s grant of the rights and licenses to Ipsen hereunder, Ipsen shall, during each applicable Royalty Term, pay to Sutro a royalty on worldwide aggregate Net Sales of Licensed Products for each Calendar Year at the percentage rates set forth in Table 7.5 below (subject to Section 7.6 (Adjustments to Royalty Payments)) (“Royalty Payments”):


Table 7.5 – Royalty Rates for Licensed Products

[*]	[*]
[*]	[*]
[*]	[*]
[*]	[*]

[*]

(b)

Royalty Payment Calculation. In the event certain Net Sales are subject to the royalty reductions set forth in Section 7.6, Ipsen shall calculate the royalty reductions as follows: Ipsen shall calculate the proportion of total Net Sales for the applicable period that are subject to royalty reduction of a particular percentage pursuant to Section 7.6 and shall apply the appropriate royalty reduction as if the Net Sales entitled to that reduction percentage make up that proportion of Net Sales within each of the relevant Net Sales bands.

7.6

Adjustment to Royalty Payments.

(a)

Lack of Valid Claims and Know How Royalty. Subject to Section 7.6(d) (Royalty Floor), on a country-by-country basis in the Territory in any country in which it violates Applicable Law to charge the same royalty on a product after expiration of a patent, during any Calendar Quarter of the Royalty Term in any such country in which the Licensed Product is not Covered by a Valid Claim of any of the Sutro Patents, Sutro Manufacturing Patents or CFE Patents in such country, then the Royalty Payments due to Sutro pursuant to Section 7.5 (Royalty Payments for Licensed Products) for the Licensed Product in such country will be reduced by [*] during any such Calendar Quarter.

(b)

Generic/Biosimilar. If, during the Royalty Term, there is a Generic/Biosimilar Competition with the Licensed Product in a country, and if the aggregate units of the Licensed Product sold in any Calendar Quarter in such country during that Calendar Quarter following introduction of such Generic/Biosimilar Competition have each fallen by at least [*] in that country as compared to the average quarterly total aggregate units of the Licensed Products sold in such country during the last full [*] Calendar Quarters immediately prior to the Calendar Quarter in which such Generic/Biosimilar Products were first introduced, where unit volume sales will be identified and calculated based on relevant information published by IQVIA, any successor to IQVIA, or any other similar Third Party source reasonably agreed upon by the Parties, then the Royalty Payments due to Sutro pursuant to Section 7.5 (Royalty Payments for Licensed Products) for the Licensed Product in such country will be reduced by [*] in such Calendar Quarter.

(c)

Identified Third Party License.

(i)

In addition to the Stanford Agreement, which shall be at the sole cost and expense of Sutro, if during the Term, either Party determines that a license under any Patent Rights controlled by a Third Party is necessary to Develop, Manufacture, Commercialize or otherwise exploit the Licensed Compound or the Licensed Product (“Identified Third Party Rights”), then it will so notify the other Party. Sutro will have the first right to acquire rights to any such Identified Third Party Rights from such Third Party (whether by acquisition or license) and if Sutro intends to acquire such rights, then Sutro will notify Ipsen of such intention within [*] of receipt of Ipsen’s written request to do so and Section 2.6 shall apply. If Sutro fails to so notify Ipsen (or notifies Ipsen of its intention not to so acquire such rights within such [*] period) or otherwise fails after the date of Ipsen’s written request to acquire rights under such Identified Third Party Rights, then Ipsen will have the right to acquire rights under such Identified Third Party Rights from such Third Party. If thereafter Ipsen so acquires such rights, then such Patent Rights will be included in the Ipsen Patent Rights, as applicable and, subject to any Royalty Payments adjustment pursuant to this Section 7.6, and Ipsen will be solely responsible for all payments owed to such Third Party in consideration for the acquisition of rights to such Identified Third Party Rights (whether by acquisition or license) or the practice thereunder by or on behalf of Ipsen.

(ii)

If Ipsen so acquires such rights, Ipsen will then be entitled to deduct from any amount payable to Sutro under Section 7.5(a), an amount equal to not more than [*] of any royalties payable by Ipsen, its Affiliates or Sublicensees to Third Parties in the Calendar Quarter pursuant to such Identified Third Party Rights in respect of Net Sales of the Licensed Product of the specific units subject to the royalty, on a unit-by-unit basis.

(d)

Royalty Floor. Notwithstanding the foregoing, under no circumstances shall the deductions under this Section 7.6 result in the amount payable to Sutro being reduced by more than [*] compared with the amount otherwise payable under Section 7.5(a), on a unit-by-unit basis. For clarity, credits for reductions not exhausted for sale of any unit of Licensed Product are not applied to sales of other Licensed Products sold in that Calendar Quarter or any future Calendar Quarter.

7.7

Timing of Payment. Royalty Payments payable under Section 7.5(a) shall be payable on actual Net Sales and shall accrue at the time the Licensed Product is delivered. Royalty obligations that have accrued during a particular Calendar Quarter shall be paid, on a Calendar Quarter basis, within [*] after the end of each Calendar Quarter during which the royalty obligation accrued.

7.8

Mode of Payment and Currency; Invoices.

(a)

Currency. All payments to Sutro hereunder shall be made by deposit of USD in the requisite amount to such bank account as Sutro may from time to time designate by written notice to Ipsen. With respect to sales not denominated in USD, Ipsen shall convert applicable sales in foreign currency into USD by using the exchange rate as published by the Wall Street Journal, Eastern Edition, under the heading “Currency Trading” averaged on the last Business Day of each of the [*] consecutive calendar months constituting the Calendar Quarter in which the payment was earned. Ipsen will bear any loss of exchange or value and pay any expenses incurred in the transfer or conversion to U.S. dollars. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Sutro. The Parties may vary the method of payment set forth herein at any time upon mutual written agreement, and any change shall be consistent with the local Applicable Law at the place of payment or remittance.

(b)

Invoices. Sutro shall address its invoices to:

7.9

Royalty Reports and Records Retention. Within [*] after the end of each Calendar Quarter following the First Commercial Sale of any Licensed Product, Ipsen shall deliver to Sutro, together with the applicable payment due for such Calendar Quarter, a written report, on a country-by-country basis, summarizing the total amount of applicable payments, if any, received during such Calendar Quarter. Such report shall include, on a country-by-country basis (i) the Gross Sales of Licensed Products subject to payments to Sutro for such Calendar Year, (ii) amounts deducted by category (following the definition of Net Sales) from such Gross Sales to calculate Net Sales, (iii) a calculation by category of any applicable reductions under Section 7.6 and (iv) a calculation of the amount of royalty payment due on such Net Sales. Such report shall be deemed Confidential Information of Ipsen subject to the obligations of Article 9 of this Agreement. Further, each such royalty report shall indicate Gross Sales and Net Sales in each country’s currency, the applicable royalty rate, the royalties payable for each country in such country’s currency, the applicable exchange rate to convert from each country’s currency to U.S. Dollars, and the royalties payable in U.S. Dollars. For [*] (or such longer period as required by Applicable Law) after each sale of each Licensed Product occurs, Ipsen shall, and shall ensure that its Affiliates and its and their Sublicensees, keep complete and accurate records of such sale in sufficient detail to confirm the accuracy of the payments made to Sutro hereunder.

7.10

Late Payments. In the event that any payment due under this Agreement that is past due, the payment shall accrue interest from the date due at the lesser of (i) the thirty (30)-day United States dollar prime rate effective for the date that the payment was due as reported by the Wall Street Journal, Internet Edition at www.wsj.com in the “Money Rates” tab on the date such payments are overdue, plus [*] per annum and (ii) the maximum legal annual interest rate, calculated on the total number of days that the payment is delinquent, compounded daily. The payment of such interest shall not limit the Party entitled to receive payment from exercising any other rights it may have as a consequence of the lateness of any payment.

7.11

Audits.

(a)

Royalty Audit.

(i)

Audits Generally. During the Royalty Term and for one year thereafter, and not more than once in each Calendar Year, Ipsen shall permit, and shall cause its Affiliates and its and their Sublicensees to permit, an independent certified public accounting firm of nationally recognized standing selected by Sutro, and reasonably acceptable to Ipsen or such Affiliate or Sublicensee to the extent such independent auditor is and remains free from conflicts of interest, to have access to and to review, during normal business hours upon reasonable prior written notice, with at least a [*] notice, the applicable records of Ipsen or its Affiliates or its or their Sublicensee to verify the accuracy of the reports and payments under this Article 7. Such review may cover the records for sales made in any Calendar Year ending not more than [*] prior to the date of such request (or such longer period as required by Applicable Law). The independent accounting firm shall disclose to Sutro and Ipsen only whether the reports are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Sutro. For clarity, Sutro shall have no access to the books and

records and other raw data of Ipsen in connection with such audit, except to the extent disclosed by the independent accounting firm pursuant to the two previous sentences.

(ii)

Audit-Based Reconciliation. If such independent accounting firm concludes that additional payments were owed during such period, and Ipsen agrees with such calculation, Ipsen shall pay the additional undisputed payments within [*] after the date Sutro delivers to Ipsen such accounting firm’s written report, with any late payments due pursuant to Section 7.10 based on the original due date. If such accounting firm concludes that an overpayment was made, such overpayment shall be fully creditable against amounts payable in subsequent payment periods. Sutro shall pay for Sutro’s auditor’s cost for any audit conducted by Sutro, unless Ipsen has underpaid Sutro by (i) [*] or (ii) [*], for the audited period, in which case Ipsen shall pay for the costs of Sutro’s auditor.

(iii)

Audit Confidentiality. Each Party shall treat all information that it receives under this Section 7.11 in accordance with the confidentiality provisions of Article 9 of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the other Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement, except to the extent necessary for such Party to enforce its rights under this Agreement.

(b)

Cost of Goods Audit.

Sutro will (a) keep complete, true, and accurate books and records in accordance with its accounting standards, in relation to the Cost of Goods billed or invoiced for Licensed Compound and Licensed Product in sufficient detail to enable amounts owed or payable to Sutro be determined; and (b) maintain such books and records for at least [*] after they are incurred. During the Royalty Term and for one year thereafter, Sutro shall permit, and shall cause its Affiliates to permit, an independent certified public accounting firm of nationally recognized standing selected by Ipsen, and reasonably acceptable to Sutro or such Affiliate, to have access to and to review, during normal business hours upon reasonable prior written notice, the applicable books and records of Sutro and its Affiliates to verify the accuracy of the Cost of Goods billed or invoiced to Ipsen under Article 5. Sections 7.11(a)(i), (ii) and (iii) shall apply mutatis mutandis to Ipsen’s right to audit the Cost of Goods.

7.12

Taxes.

(a)

Withholding Tax. Each Party shall be responsible for the payment of any and all Taxes levied against it on account of the royalties and other payments paid under this Agreement. If Applicable Law requires that Taxes be deducted or withheld from royalties or other payments paid under this Agreement, the paying Party shall (i) deduct those Taxes and interests from the payment or from any other payment owed by the paying Party hereunder; (ii) pay the Taxes to the proper Governmental Body; (iii) send evidence of the obligation together with proof of Tax payment to the non-paying Party within [*] following such payment; (iv) remit the net amount, after deductions or withholding made under this Section 7.12; and (v) cooperate with the non-paying Party in any way reasonably requested by the non-paying Party, to obtain available reductions, credits or refunds of such Taxes; provided, however, that the non-paying Party shall reimburse the paying Party for the paying Party’s Out-of-Pocket Expenses incurred in providing such assistance. Such paying Party shall submit to the non-paying Party appropriate proof of payment of the taxes as well as the official receipts within [*]. Notwithstanding the foregoing, if any Ipsen assigns this Agreement or changes its domicile, and, as a result, any additional taxes are required to be withheld with respect to payments made to Sutro, such Ipsen shall be responsible for all such additional withholding taxes and shall pay Sutro such increased amounts as are necessary to ensure that Sutro receives the same amount (after any required deduction and withholding of taxes, including with respect to any additional amounts payable under this sentence) as it would have received had no such assignment or change in domicile been made.

(b)

Value Added Tax. It is understood and agreed between the Parties that any payments made by Ipsen under this Agreement are exclusive of any value added or similar Tax imposed upon

such payment and that Ipsen shall be responsible for the payment of any and all Taxes levied on account of any payments paid to Sutro by Ipsen. Ipsen is entitled to receive a proper tax invoice where any Value Added Tax amount is shown separately.

Notwithstanding Sections 8.3(a)(i) to (iv) (inclusive), Ipsen agrees to assign and hereby assigns to Sutro all right, title and interest in any and all Platform IP and all right, title and interest in any modification, improvement or derivative of Sutro Know-How or Sutro Manufacturing Know-How that is discovered, generated, conceived or reduced to practice (constructively or actually) by or on behalf of Ipsen or any of its Affiliates or any of its or their Sublicensees (including by any of its or their employees, agents, or independent contractors, or any combination thereof). Platform IP shall be included in Sutro Technology or Sutro Manufacturing IP, as applicable.

(vi)

Each Party shall cause its Affiliates, employees, consultants, Sublicensees, agents, or independent contractors to assign to the Party, such Person’s right, title and interest in and to any Inventions as is necessary to enable such Party to fully effect the ownership of Inventions. Each Party shall also include provisions in its relevant agreements with Third Parties performing activities on its behalf pursuant to this Agreement, or any Sublicensee, that give effect to the intent of this Section 8.3. Each Party agrees to provide reasonable cooperation to the other Party, and shall cause its Affiliates, employees, consultants, Sublicensees, agents, or independent contractors to, cooperate with such Party and take all reasonable additional actions and execute such agreements, instruments and documents as may be reasonably required to perfect such Party’s right, title and interest in and to Inventions as set forth in this Section 8.3, including by executing and delivering all documents reasonably required to evidence or record any assignment pursuant to this Agreement;

(vii)

Each Party will be responsible for patent-related renumeration obligations pursuant to their employees, consultants, and agents as required by contract or pursuant to jurisdiction specific renumeration laws.

Except as explicitly set forth in this Agreement, neither Party shall be deemed by estoppel or implication to have granted the other Party any license or other right to any intellectual property of such Party. For clarity and notwithstanding anything to the contrary in this Agreement, Sutro retains all right, title and interest in Sutro Technology, Regulatory Materials, Platform IP, Sutro Technology, [*] CFE Technology, Sutro Manufacturing Technology, Sutro Manufacturing IP, and Sutro’s Confidential Information, each subject to any licenses granted in this Agreement, and such right, title and interest is not assigned or otherwise transferred to Ipsen, its Affiliate or any Third Party as the result of any terms set forth in this Agreement, including without limitation terms providing for the “transfer” of technology, data, Know-How or documents pursuant to Section 2.3, 2.4, 5.4(b), or 5.5.

8.4

Patent Prosecution and Maintenance.

(a)

Product Specific Patents. Subject to the terms of this Agreement, Ipsen shall have the first right, but not the obligation (subject to Section 8.4(b)), to file, prosecute and maintain the Product Specific Patents in Sutro’s name. Ipsen shall bear all costs and expenses of filing, prosecuting and maintaining the Product Specific Patents. Ipsen shall (i) use independent patent counsel reasonably acceptable to Sutro, (ii) keep Sutro informed of the status of the filing and prosecution of the Product Specific Patents or related proceedings (e.g. interferences, oppositions, reexaminations, reissues, revocations or nullifications) in a timely manner, (iii) give Sutro a reasonable opportunity to comment

on all patent prosecution strategy and decisions regarding the Product Specific Patents, and (iv) take into consideration the advice and recommendations of Sutro; provided, however that Sutro does so promptly and consistent with any applicable filing deadlines; and provided further, that in the event Ipsen disagrees with Sutro’s comments and recommended actions, Ipsen will have final decision-making authority with respect to the subject matter of such disagreement, provided further that Ipsen shall not expressly abandon any Product Specific Patents without Sutro’s prior written consent. If Ipsen intends to allow any Product Specific Patent to lapse or become abandoned in the United States, France, Germany, Italy, Spain, the United Kingdom, China or Japan, or to not file an application for any Product Specific Patent in each of these countries, it will notify and consult with Sutro with respect to such decision or intention at least [*] prior to the date upon which the subject matter of such Patent Right will become unpatentable or such Patent Right will lapse or become abandoned (or such other reasonable time under the circumstances if Ipsen became aware of such matters with less than [*] remaining prior to such deadline), and, if after such consultation between the Parties, Ipsen still intends not to prosecute and maintain such Patent Right, Sutro shall have the right (but not the obligation) to assume the prosecution and maintenance of such Product Specific Patent in Sutro’s name.

(b)

In such case, Sutro shall have the right (but not the obligation) to pursue the filing or support the continued prosecution or maintenance of such Product Specific Patent. If Sutro elects to continue prosecution or maintenance of any such Product Specific Patent, then, notwithstanding Section 2.1, Ipsen shall not have a license under Section 2.1 to such Product Specific Patent. In such event, Ipsen shall promptly deliver to Sutro all prosecution files associated with such Product Specific Patent in such country to allow Sutro to continue such filing, prosecution or maintenance.

(c)

Cooperation. With respect to all filing, prosecution and maintenance of the Product Specific Patents, Sutro will: (a) execute any instruments to document its ownership required to enable Ipsen to exercise its rights under this Section 8.4, as reasonably requested by Ipsen; (b) use Commercially Reasonable Efforts to make its employees, agents and consultants reasonably available to Ipsen (or to Ipsen’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable Ipsen to undertake its filing, prosecution and maintenance responsibilities; and (c) use Commercially Reasonable Efforts to cooperate, if necessary, with Ipsen in gaining patent term extensions. The Parties will act in good faith to coordinate efforts under this Agreement to minimize or avoid interference with such filings, prosecution and maintenance by the Parties.

(d)

Patent Term Extension. Subject to this Section 8.4(d), Ipsen shall be solely responsible, in Ipsen’s name, for making decisions regarding and obtaining patent term extensions wherever available for Product Specific Patents. If there is an option to extend the patent term for only one (1) Product Specific Patent, Ipsen shall consult with Sutro before making the election but has no obligation to make such election. If, however, more than one (1) Product Specific Patent is eligible for extension, Ipsen shall select a strategy that is intended to maximize patent protection and commercial value for the Licensed Products, in consultation with Sutro but provided that Ipsen shall have the final say regarding any such extension decisions. Sutro will reasonably cooperate with Ipsen in making such filings or actions, for example and without limitation, reasonably executing any required authorizations to apply for such patent term extension.

(e)

Ipsen Patent. Ipsen shall bear all costs and expenses of filing, prosecuting and maintaining Ipsen Patents, and Sutro shall have no rights with respect thereto (except as expressly set forth in Section 8.3(a)(v) or 12.7(d)(i)).

(f)

Sutro Patent. Except as provided in Section 8.4(a) to (d) (inclusive), Sutro shall bear all costs and expenses of filing, prosecuting and maintaining Sutro Patents and Sutro Manufacturing Patents, other than Product Specific Patents, and Ipsen shall have no rights with respect thereto.

(g)

Joint Patent.

If the First Right Party intends to allow any of Its Joint Patents to lapse or become abandoned in the United States, France, Germany, Italy, Spain, the United Kingdom, China or Japan, or to not file an application for any of Its Joint Patents in each of these countries, it will notify and consult with the Second Right Party with respect to such decision or intention at least [*] prior to the date upon which the subject matter of such Patent Right will become unpatentable or such Patent Right will lapse or become abandoned (or such other reasonable time under the circumstances if the First Right Party became aware of such matters with less than [*] remaining prior to such deadline), and, if after such consultation between the Parties, the First Right Party still intends not to prosecute and maintain such Patent Right, the Second Right Party shall have the right (but not the obligation) to assume the prosecution and maintenance of such Patent Right in its name.

(iii)

Election Not to File and Prosecute Joint Patents. If a Party elects not to file or to continue to prosecute or maintain an Its Joint Patent, then it shall notify the Second Right Party in writing at least [*] before any deadline applicable to the filing, prosecution or maintenance of such Its Joint Patent, as the case may be, or any other date by which an action must be taken to establish or preserve such Its Joint Patent in the applicable country. In such case, the Second Right Party shall have the right (but not the obligation) to pursue the filing or support the continued prosecution or maintenance of such Its Joint Patent. In such event, the First Right Party shall promptly deliver to the Second Right Party all prosecution files associated with such Its Joint Patent in such country to allow the Second Right Party to continue such filing, prosecution or maintenance. If the Second Right Party is Sutro and Sutro elects to continue prosecution or maintenance of any such Its Joint Patent, then, notwithstanding Section 2.1, Ipsen shall not have a license under Section 2.1 to such Its Joint Patent.

(iv)

Cooperation.

(v)

Patent Term Extension. The First Right Party shall be solely responsible, in the First Right Party’s name, for making decisions regarding and obtaining patent term extensions wherever available for Its Joint Patents. If there is an option to extend the patent term for only one (1) Its Joint Patent, the First Right Party shall consult with the Second Right Party before making the election but has no obligation to make such election. If, however, more than one (1) Its Joint Patent is eligible for extension, the First Right Party shall select a strategy that is intended to maximize patent protection and commercial value for the Licensed Products, in consultation with the Second Right Party but provided that the First Right Party shall have the final say regarding any such extension decisions. The Second Right Party will reasonably cooperate with the First Right Party in making such filings or actions, for example and without limitation, reasonably executing any required authorizations to apply for such patent term extension.

8.5

Enforcement of Patents and Know-How.

(a)

Notice. If either Party becomes aware of any actual, alleged or threatened infringement, unauthorized use, misappropriation, ownership claim, threatened infringement or other such activity by a Third Party with respect to any Product Specific Patent or Joint Patent is occurring or likely, or if a Third Party claims that any Product Specific Patent or Joint Patent is invalid or unenforceable, the Party possessing such knowledge or belief shall notify the other Party (any of the foregoing, “Third Party Infringement”) and provide it with details of such Third Party Infringement that are known by such Party.

(b)

Right to Bring an Action.

(i)

As between the Parties, Ipsen shall have the first right to attempt to resolve any Third Party Infringement, including by filing an infringement suit, defending against a motion for declarative judgment regarding non-infringement, invalidity or unenforceability or other similar action, with respect to (1) a Product Specific Patent Controlled by a Party except to the extent Ipsen elected not to file or to continue to prosecute or maintain such Product Specific Patent and (2) a Ipsen Joint Patent to the extent Ipsen elected to exercise its right to file, prosecute and maintain such Ipsen Joint Patent (each, an “Action”) and to compromise or settle any such Third Party Infringement. At Ipsen’s reasonable request, Sutro shall promptly provide Ipsen with documentation to evidence that Ipsen is validly empowered by Sutro to take such an Action. Sutro shall have the right, at its own expense, to retain its own counsel with respect to its participation in any such Action; provided, that Sutro is obligated to join Ipsen in such Action at Ipsen’s cost if Ipsen reasonably determines that joining is necessary to demonstrate “standing to sue.” If Ipsen does not intend to prosecute or defend an Action, Ipsen shall promptly inform Sutro thereof in writing (and, to the extent reasonably practicable, at least [*] prior to any deadline applicable to any such Action, or otherwise as early as reasonably practical), and Sutro shall have the right to attempt to resolve such Action as the Party controlling such Action. For clarity, as between the Parties, Sutro shall have the first right to attempt to resolve any Third Party Infringement, including by filing an infringement suit, defending against a motion for declarative judgment regarding non-infringement, invalidity or unenforceability or other similar action, with respect to (1) a Product Specific Patent Controlled by a Party to the extent Ipsen elected not to file or to continue to prosecute or maintain such Product Specific Patent and (2) a Ipsen Joint Patent to the extent Ipsen not elected to exercise its right to file, prosecute and maintain such Ipsen Joint Patent, and to compromise or settle any such Third Party Infringement.

(ii)

The Party controlling the Action under Section 8.5(b)(i) shall: (i) keep the other Party promptly informed with respect to such Action, (ii) in good faith, consult with, and give reasonable consideration to, any comments made by the other Party related to such Action, and (iii)

provide the other Party with copies of all material documents (e.g., complaints, answers, counterclaims, material motions, orders of the court, memoranda of law and legal briefs, interrogatory responses, depositions, material pre-trial filings, expert reports, affidavits filed in court, transcripts of hearings and trial testimony, trial exhibits and notices of appeal) filed in, or otherwise relating to, such Action. If Ipsen fails to abate such Third Party Infringement in the Territory or to file an Action to abate such Third Party Infringement in the Territory within [*] after receiving or giving notice pursuant to Section 8.5(a) or if Ipsen decides to discontinue the prosecution of any such Action without abating such Third Party Infringement, then Sutro shall have the right, but not the obligation, to enforce (or take over the enforcement of) the Product Specific Patents, as applicable, against such Third Party Infringement in the Territory at its own expense as it reasonably determines appropriate, in which case Sutro shall keep Ipsen reasonably informed as to the status of such Action and shall consider in good faith the comments of Ipsen and the interests of Ipsen in such Action. The Parties shall cooperate in good faith to use Commercially Reasonable Efforts to ensure that each Person that participates in, or receives any information about, any Action in accordance with this Section 8.5(b) shall use reasonable efforts to protect all applicable confidential information and preserve all applicable attorney-client privilege and work product protections.

(c)

Costs of an Action. Subject to the respective indemnity obligations of the Parties set forth in Article 11, the Party controlling an Action under Section 8.5(b) shall pay all costs associated with such Action, other than (subject to Section 8.5(e)) the expenses of the other Party if the other Party elects to join such Action (as provided in the last sentence of this paragraph); provided, that, if Sutro is obligated to join any Action to demonstrate “standing to sue” pursuant to Section 8.5(b)(i), then Ipsen shall reimburse Sutro for all costs incurred by Sutro in connection with joining such Action. Each Party shall have the right to join an Action at its own expense.

(d)

Settlement. Neither Party shall settle or otherwise compromise any Action: (i) by admitting that any Product Specific Patent is invalid or unenforceable, whether in whole or in part, (ii) in a way that adversely affects or would be reasonably expected to materially adversely affect the validity or enforceability of any Product Specific Patent or the rights or benefits of the other Party hereunder or (iii) in a way that imposes any costs or liability on, or involves any admission by, the other Party, in each case, without the other Party’s prior written consent.

(e)

Reasonable Assistance. The Party not enforcing or defending Product Specific Patents shall provide reasonable assistance to the other Party, including reasonably providing access to relevant documents and other evidence and making its employees or representatives available, subject to the other Party’s reimbursement of any reasonable Out-of-Pocket Expenses incurred on an on-going basis by the non-enforcing or non-defending Party in providing such assistance.

(f)

Distribution of Amounts Recovered. Any amounts recovered by the Party taking an Action pursuant to this Section 8.5, whether by settlement or judgment, shall be allocated in the following order: (i) first, to reimburse each Party’s costs, including Out-of-Pocket Expenses, incurred provided that if amounts recovered are insufficient to reimburse all such costs and expenses incurred by both Parties, then such recovered amounts shall be shared pro rata in proportion to the relative amount of such costs and expenses incurred by each Party; (ii) second, any remaining amount of such recovery shall be retained by or paid to the Party bringing the Action; provided that if Ipsen is the Party taking such Action, any such remaining amount that is attributable to loss of sales or profits with respect to any Licensed Product (whether by judgment or otherwise) shall be treated as “Net Sales” in the Calendar Quarter in which the money is actually received and any royalties pursuant to Section 7.5(a) shall be payable by Ipsen to Sutro with respect thereto.

(g)

Sutro Joint Patents. As between the Parties, Sutro shall have the first right to attempt to resolve any Third Party Infringement, including by filing an infringement suit, defending against a motion for declarative judgment regarding non-infringement, invalidity or unenforceability or other similar action, with respect to any Sutro Joint Patents (regardless of whether Sutro exercised its right to

prosecute such Patent Rights) (each, also an “Action”) and to compromise or settle any such Third Party Infringement and other terms in Sections 8.5(b) to (f) shall apply mutatis mutandis.

(h)

Ipsen Patents. Ipsen shall have the sole right and authority, but not the obligation, to enforce Ipsen Patents, other than Product Specific Patents, against any Third Party infringer.

(i)

Sutro Patents. Sutro shall have the sole right and authority, but not the obligation, to enforce Sutro Patents or Sutro Manufacturing Patents, other than Product Specific Patents, against any Third Party infringer.

8.6

Third Party Actions Claiming Infringement

(a)

Notice. If a Party becomes aware of any Third Party Action, such Party shall promptly notify the other Party of all details regarding such Third Party Action that is reasonably available to such Party.

(b)

Right to Defend. Ipsen shall have the first right, at its sole expense, but not the obligation, to defend a Third Party Action described in Section 8.6(a) in the Field and to compromise or settle such Third Party Action, each except to the extent such Third Party Action relates specifically to any Platform Patents or CFE Patents, in which case Sutro shall have the first right for each of the foregoing. If the Party having the first right to defend a Third Party Action declines or fails to assert its intention to defend such Third Party Action within [*] after sending (in the event that such Party is the notifying Party) or receipt (in the event that the other Party is the notifying Party) of notice under Section 8.6(a), then the other Party shall have the right, but not the obligation, to defend such Third Party Action; provided that if Sutro declines to defend a Third Party Action, then Ipsen shall have an obligation to defend it, notwithstanding the previous sentence. The Party defending such Third Party Action shall have the sole and exclusive right to select counsel for such Third Party Action.

(c)

Consultation. The Party defending a Third Party Action pursuant to Section 8.6(b) shall be the “Controlling Party.” The Controlling Party shall consult with the non-Controlling Party on all material aspects of the defense. The non-Controlling Party shall have a reasonable opportunity for meaningful participation in decision-making and formulation of defense strategy. The Parties shall reasonably cooperate with each other in all such actions or proceedings. The non-Controlling Party will be entitled to be represented by independent counsel of its own choice at its own expense.

(d)

Appeal. In the event that a judgment in a Third Party Action is entered against the Controlling Party and an appeal is available, the Controlling Party shall have the first right, but not the obligation, to file such appeal. In the event the Controlling Party does not desire to file such an appeal, it will promptly, in a reasonable time period (i.e., with sufficient time for the non-Controlling Party to take whatever action may be necessary) prior to the date on which such right to appeal will lapse or otherwise diminish, permit the non-Controlling Party to pursue such appeal at such non-Controlling Party’s own cost and expense. If Applicable Law requires the other Party’s involvement in an appeal, the other Party shall be a nominal party of the appeal and shall provide reasonable cooperation to such Party at such Party’s expense.

(e)

Costs of an Action. Subject to the respective indemnity obligations of the Parties set forth in Article 11, the Controlling Party shall pay all costs associated with such Third Party Action other than the expenses of the other Party if the other Party elects to join such Third Party Action (as provided in the last sentence of this paragraph). Each Party shall have the right to join a Third Party Action defended by the other Party, at its own expense.

(f)

No Settlement Without Consent. Neither Party shall settle or otherwise compromise any Third Party Action: (i) by admitting that any Product Specific Patent is invalid or unenforceable, whether in whole or in part, (ii) in a manner that adversely affects or would be reasonably expected to adversely affect any rights and benefits of the other Party or (iii) in a way that imposes any costs or

liability on, or involves any admission by, the other Party, in each case, without the other Party’s prior written consent.

Article 13

DISPUTE RESOLUTION

13.1

Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish under this Article 13 procedures to facilitate the resolution of disputes arising under this Agreement (other than any disputes relating to matters which under this Agreement Sutro has sole decision-making authority (each, a “Non-Escalable Dispute”)), in an expedient manner by mutual cooperation and without resort to litigation. In the event that the Parties are unable to resolve such dispute through diligent review and deliberation by the Senior Executives within [*] from the day that one Party had designated the issue as a dispute in written notice to the other Party, then either Party shall have the right to escalate such matter to the respective Chief Executive Officers as set forth in Section 13.2.

13.2

Escalation to Senior Executive Officers. Either Party may, by written notice to the other Party, request that a dispute (other than a Non-Escalable Dispute) that remains unresolved by the respective Senior Executives or his/her designated senior representative for a period of [*] as set forth in Section 13.1 arising between the Parties in connection with this Agreement, or a dispute relating to material breach, be resolved by the respective Chief Executive Officers or his/her designated senior representative, within [*] after referral of such dispute to them. If the Chief Executive Officers cannot resolve such dispute within [*] after referral of such dispute to them, then, at any time after such [*] period, either Party may proceed to enforce any and all of its rights with respect to such dispute.

13.3

Binding Arbitration. Except as otherwise expressly set forth in this Agreement, if such Chief Executive Officers do not resolve the dispute in accordance with the time-periods set forth in Section 13.2 then, either Party may at any time submit the dispute to be finally settled by arbitration administered in accordance with the ICC International Arbitration Rules then in effect of the International Court of Arbitration of the International Chamber of Commercial (the “ICC”) in effect at the time of submission. The arbitration will be heard and determined by three arbitrators, each of whom will be impartial and independent of the Parties. Each Party will appoint one arbitrator and the third arbitrator will be selected by the two Party-appointed arbitrators, or, failing agreement, by the ICC. Such arbitration will take place in [*], in the English language. The arbitration award so given will,

absent manifest error, be a final and binding determination of the dispute, and will be fully enforceable in any court of competent jurisdiction. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration unless the final award decides that one Party shall pay some or all of the other Party’s legal costs. Except to the extent necessary to comply with Applicable Law, legal process, or a court order or to enforce a final settlement agreement or secure enforcement of any arbitration award, the Parties agree that the existence, terms and content of any arbitration, all information and documents disclosed in any arbitration or evidencing any arbitration results, award, judgment or settlement, or the performance thereof, and any allegations, statements and admissions made or positions taken by either Party in any arbitration, shall be treated and maintained in confidence and are not intended to be used or disclosed for any other purpose or in any other forum.

13.4

Injunctive Relief. No provision herein shall be construed as precluding a Party from bringing an action for injunctive relief or other equitable relief prior to the initiation or completion of the above procedure. Each Party acknowledges and agrees that the restrictions and obligations set forth in Section 8.3 and in Article 9 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of such Section or Article may result in irreparable injury to such other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Section or Article, the non-breaching Party shall be authorized and entitled to seek, without any requirement to post bond, from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance, and an equitable accounting of all earnings, profits, and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity.

13.5

No Limitation of Remedies. The Parties hereby agree that no remedy conferred by any of the specific provisions of this Agreement, including, without limitation, Section 5.1(a), is intended to be exclusive of any other remedy, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute or otherwise.
