2.1. Grants to Sanofi. Lexicon hereby grants to Sanofi:

2.1.1. an exclusive (including with regard to Lexicon and its Affiliates, but subject to a retained right by Lexicon and its Affiliates to exercise their rights and perform their obligations with respect to Licensed Products under this Agreement) license (or sublicense), with the right to grant sublicenses in accordance with Section 2.3, under the Lexicon Patents, the Lexicon Know-How and Lexicon’s interests in the Joint Intellectual Property Rights, to Exploit Licensed Products (and, for clarity,

with the Securities and Exchange Commission.

the Licensed Compounds contained therein) for any and all uses in the Field in the Territory and, in the case of any Terminated Territory, to Develop and Manufacture Licensed Products (including the Licensed Compounds contained therein) in any country in the Terminated Territory in support of Development and Commercialization in the Field in the Territory; and

2.1.2. an exclusive (including with regard to Lexicon and its Affiliates, but subject to a retained right by Lexicon and its Affiliates to exercise their rights and perform their obligations with respect to Licensed Products under this Agreement) license (or sublicense) and right of reference, with the right to grant sublicenses and further rights of reference in accordance with Section 2.3, under the Retained Regulatory Documentation to Exploit Licensed Products in the Field in the Territory and, in the case of any Terminated Territory, to Develop and Manufacture Licensed Products in any country in the Terminated Territory in support of Development and Commercialization in the Field in the Territory.

Lexicon agrees, pursuant to a separate trademark license agreement to be negotiated by the Parties, but for no additional financial consideration, to grant to Sanofi a royalty-free, non-exclusive license to use Lexicon’s Corporate Names solely as required by this Agreement or Applicable Law in order to Manufacture the Licensed Products (including the Licensed Compounds contained therein) in the Field in the Territory and for no other purpose.

2.2. Grants to Lexicon. Sanofi hereby grants to Lexicon a non-exclusive, royalty-free (sub)license and right of reference, without the right to grant sublicenses or further rights of reference (except to permitted subcontractors as provided in Section 3.1.5), under the Sanofi Patents, the Sanofi Know-How and the Assigned Regulatory Documentation and Sanofi’s interests in the Joint Intellectual Property Rights, to perform Lexicon’s obligations as set forth herein or in the Ancillary Agreements. Except as expressly provided herein, Sanofi grants no other right or license, including any rights or licenses to the Sanofi Patents, the Sanofi Know-How, Sanofi’s interest in the Joint Intellectual Property, Assigned Regulatory Documentation or any other Patent or intellectual property rights not otherwise expressly granted herein.

2.3. Sublicenses. Sanofi shall have the right to grant sublicenses (or further rights of reference) to its Affiliates throughout the Territory. In the Major Markets (except with respect to Manufacturing of the Licensed Product or Licensed Compounds in the Major Markets), for so long as the applicable Major Market remains part of the Territory, Sanofi shall have the right to grant sublicenses (or further rights of reference) to Third Parties (other than to service providers) only with Lexicon’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed. In all other cases, including service providers and Manufacturing worldwide, Sanofi shall have the right to grant sublicenses (or further rights of reference) to Third Parties, through multiple tiers of (sub)licensees, under the licenses and rights of reference granted in Section 2.1; provided however, that Sanofi shall provide Lexicon with prompt written notice of any such sublicense (or further right of reference). Notwithstanding any sublicenses granted by Sanofi, Sanofi shall remain responsible and primarily liable for the performance of its obligations and the performance of its (sub)licensees hereunder.

2.4.1. Lexicon shall and shall cause its Affiliates and Lexicon CMOs to disclose and make available to Sanofi, the Regulatory Documentation, Lexicon Know-How and other Information and Inventions, in each case, as set forth on Schedule 2.4 and existing as of the Effective Date (the materials required to be disclosed under this sentence, “Transferred Materials”) within [**] after the

Confidential materials omitted and filed separately

Effective Date. During the Term, each Party shall provide to the other Party all material Sanofi Know-How and Lexicon Know-How, as the case may be, that is reasonably necessary or useful for the other Party to perform its activities under this Agreement or any Ancillary Agreement and that comes into existence after the Effective Date, promptly after the earlier of the development, making, conception or reduction to practice of such Know-How. During the Term, each Party shall provide to the other Party Joint Know-How that comes into existence after the Effective Date, promptly after the earlier of the development, making, conception or reduction to practice of such Joint Know-How by or on behalf of such disclosing Party.

2.4.2. Lexicon shall provide Sanofi with reasonable assistance required in order to transfer to Sanofi the Transferred Materials in a timely manner for Sanofi to Exploit the Licensed Products (including for clarity any adjustment to Lexicon’s existing Regulatory Documentation reasonably required by Sanofi). Without limiting the foregoing, Lexicon shall make available to Sanofi, at Lexicon’s facilities, those of Lexicon’s representatives as Sanofi may reasonably request for purposes of transferring the Transferred Materials to Sanofi or for purposes of Sanofi acquiring expertise on the practical application of such Transferred Materials or assisting on issues arising during such Exploitation.

2.4.3. All costs and expenses of Lexicon’s internal personnel and other resources and any out‑of‑pocket expenditures incurred by Lexicon in performing its obligations pursuant to this Section 2.4 shall be the responsibility of Lexicon; provided, however, that Sanofi shall be responsible for any payments required to be made to Third Parties in connection with such transfers to the extent incurred by Lexicon after the Effective Date.

2.4.4. Within [**] following the Effective Date, the Parties shall create a mutually acceptable transfer plan, detailing the timeline and responsibilities of both Parties in connection with the transfer of the Transferred Materials from Lexicon to Sanofi (the “Know-How Transfer Plan”); provided, however, that the failure to create a Know-How Transfer Plan shall not relieve Lexicon of its obligations to conduct the disclosures and transfers contemplated by this Section 2.4.

2.5. Confirmatory Patent License. Lexicon shall, if requested to do so by Sanofi, immediately enter into confirmatory license agreements in such form as may be reasonably requested by Sanofi for purposes of recording the licenses granted under this Agreement with such patent offices in the Territory as Sanofi considers appropriate. Until the execution of any such confirmatory licenses, so far as may be legally possible, Lexicon and Sanofi shall have the same rights in respect of the Lexicon Patents and be under the same obligations to each other in all respects as if the said confirmatory licenses had been executed.

2.6. Exclusivity

2.6.1. Neither Party nor any of its Affiliates shall, itself or through, with or on behalf of any Third Party, undertake in the Territory during the Royalty Term in the applicable country (i) any clinical Development of any SGLT1, SGLT2 or dual SGLT1/SGLT2 inhibitors that are not Licensed Products (a “Competing Product”), except clinical Development of a Competing Product (including the manufacture of validation batches thereof) conducted prior to the expiration of the Royalty Term in the applicable country reasonably in advance of the expiration of the Royalty Term in order to launch such Competing Product promptly following expiration of the Royalty Term or (ii) in the case of the Major Markets and the Tier 2 Countries, commercialization of any Competing Product, other than (a) pursuant to this Agreement, (b) in the case of Sanofi, Development and commercialization of a Generic Version of a

Asterisks denote omissions.

Competing Product in a country after the date on which there is no valid and unexpired Patent in such country that Covers (i) [**] or (ii) [**], (c) in the case of Sanofi, fee-for-service manufacturing of Competing Product(s) for Third Parties, or (d) in the case of Lexicon, and subject to Section 2.7, Development and commercialization of LX2761.

2.6.2. Notwithstanding Section 2.6.1, if a Party or any of its Affiliates (the “Acquiring Party”) signs a definitive agreement with respect to a merger, acquisition or other transaction by which such Acquiring Party would acquire rights (other than residual financial rights) or an entity that has rights in a Competing Product, or would be acquired by an entity that has or has Affiliates that have rights in a Competing Product, as a result of which transaction Section 2.6.1, would (but for this Section 2.6.2) be violated, then the Acquiring Party (or other acquiring or surviving entity), as the case may be, shall have [**] from the closing of such transaction to either (i) divest itself of the rights with respect to the applicable restricted activities as described in 2.6.1 (the “Restricted Rights”) or (ii) terminate all of such restricted activities with respect to such Competing Product, unless the other Party (i.e., the non-Acquiring Party) agrees in writing that such divestiture is not required. In such event, during such period (or in the case of such a writing from the other Party), the activities described in Section 2.6.1, with respect to such Competing Product shall not constitute a violation of Section 2.6.1. Any divestiture under this Section 2.6.2 may occur by either (x) an outright sale of the Restricted Rights to a Third Party, or (y) an out-license of the Restricted Rights (exclusive as to the Acquiring Party (or other acquiring or surviving entity) and its Affiliates, except that in each case ((x) and (y)) (A) the Acquiring Party (or other acquiring or surviving entity) and its Affiliates may continue manufacturing or supplying the applicable Competing Product to the licensee or acquirer for a reasonable period of time, and conduct customary transitional services for the licensee or acquirer, as applicable, but may not otherwise continue to participate in Development or commercialization of the Competing Product, and (B) the Acquiring Party (or other acquiring or surviving entity) and its Affiliates may retain residual financial rights to such Competing Product and reversion rights in the case of a termination of the out-license agreement (provided that upon such a reversion, the Acquiring Party would again be subject to the divestiture/termination requirements of this Section 2.6.2 if Section 2.6.1 were to apply upon such reversion).

2.7. LX2761 Rights

2.7.1. Development and Commercialization by Lexicon. Except for the promotional restrictions set forth in the (Co-)Promotion Terms, nothing in Section 2.6 or elsewhere in this Agreement shall restrict Lexicon from Developing and commercializing, at Lexicon’s sole discretion, LX2761 and products that include LX2761, subject to Lexicon’s obligations and Sanofi’s rights as set forth in this Section 2.7. Lexicon agrees that its Development activities under this Agreement with respect to LX4211 shall have priority over the Development of LX2761, and that Lexicon shall not prioritize LX2761 in any manner detrimental to its Development obligations with respect to LX4211 or divert material resources from its Development of LX4211 under the T1DM Development Plan without the consent of Sanofi. Except as otherwise agreed by the Parties in a definitive agreement entered into by the Parties pursuant to Section 2.7.2 or Section 2.7.3, and notwithstanding anything to the contrary elsewhere in this Agreement, all LX2761 Study Data (as defined below) shall be solely owned by Lexicon. Lexicon shall provide Sanofi a development plan describing Lexicon’s Development activities with respect to LX2761 prior to commencing clinical development for LX2761 and thereafter shall provide Sanofi with any material amendments to such development plan until Sanofi has no further option or rights hereunder with respect to the Development and commercialization of LX2761. Lexicon shall not enter into any agreements with any Third Parties that would deprive Sanofi of its rights under this Section 2.7.

The Parties shall cooperate in performing such Development activities as provided in this ARTICLE 3.

3.1.2. Development.

(i) Attached hereto as Schedule 3.1.2 is the initial plan for the Development of the Licensed Products for T1DM and T2DM in the Major Markets in the Territory as of the Execution Date (such plan, as amended from time to time in accordance with this Agreement, the “Development Plan”), which plan shall describe the Development activities and, with respect to Development activities for T2DM, the budget therefor, including the internal personnel and other resources and out‑of‑pocket expenditures required for Sanofi to perform such activities; provided that upon the earlier of (a) the Cost-Sharing Trigger Point and (b) the date upon which Lexicon has paid one hundred million Dollars ($100,000,000) of Development Costs in connection with T2DM Development under and in accordance with the Development Plan, the Development Plan shall not contain such budget.

(iv) If Lexicon elects to permanently cease all Development in T1DM before completion of the Development activities set forth in the Development Plan, Lexicon shall promptly notify Sanofi thereof, and Sanofi shall have the right, at Sanofi’s sole election, to assume and complete any such Development activities. If Sanofi exercises such right, such exercise shall be Sanofi’s sole and exclusive remedy and Lexicon’s sole and exclusive liability for any such cessation by Lexicon (but this sentence shall not limit any liability of Lexicon for a material breach of this Agreement other than its diligence obligations under Sections 3.1.2(iii) and 3.1.4).

In the event of Lexicon’s cessation of Development in T1DM in accordance with this Section 3.1.2(iv), the licenses granted by Sanofi to Lexicon under Section 2.2, the Parties’ obligations under Section 2.6.1 with respect to T1DM, the Quality Agreements under Section 3.1.2(v), the JCC, Lexicon’s rights under Section 3.2.2 to participate in meetings with Regulatory Authorities, and Lexicon’s (Co-)Promotion Rights under Section 4.8 and any (Co-)Promotion Agreement shall terminate, effective upon Lexicon’s notice with respect thereto; Sanofi shall be responsible for any and all additional T1DM Development Costs (if it exercises its right to assume and continue Development in T1DM) and all T1DM Commercialization Costs and Medical Affairs Costs; Lexicon shall not be entitled to the milestone payments contemplated by Section 7.2.1(b)(i) and Section 7.2.1(b)(ii), to the extent subsequently achieved based on Development activities subsequently conducted by Sanofi under its right to assume and continue such Development; and the royalty rates described in Section 7.3.1(ii) shall apply to all Net Sales in the United States, regardless of whether such Net Sales would otherwise constitute T1DM Net Sales or T2DM Net Sales.

(v) Quality.

(1) Within [**] after the Effective Date, but in any event prior to shipment of clinical quantities of Licensed Product or placebo pursuant to Section 6.1.1, Lexicon and Sanofi shall enter into a reasonable and customary Quality Agreement that shall set forth the terms and conditions with respect to quality regarding the conduct of the Parties’ Development activities under the Development Plan, including supply of such clinical material by Lexicon to Sanofi, which agreement shall include (a) coordination regarding inspections by Regulatory Authorities and (b) the exchange of information between the Parties regarding the foregoing and quality issues in general.

Asterisks denote omissions.

(2) The Quality Agreements shall provide for each Party’s right to conduct quality audits of the other Party and its subcontractors prior to the Technology Transfer and thereafter with respect to T1DM and T2DM clinical studies, as deemed necessary by the auditing Party to secure the regulatory status of the Licensed Product in the Territory.

(3) Each Party shall be notified reasonably in advance of any audit or inspection intended to be conducted by a Regulatory Authority at any of the other Party’s or any of its subcontractor’s facilities or operations related to the Development or Manufacture of the Licensed Products. The Parties shall reasonably cooperate with each other with respect to such audits or inspections.

(4) Promptly following the Effective Date, the Parties shall appoint quality contact persons within their respective organization, with the mission to oversee the negotiation and implementation of the Quality Agreement. The Parties shall maintain scientific records, in sufficient detail and in sound scientific manner appropriate for patent and regulatory purposes and in compliance with Applicable Law with respect to activities intended to be submitted in the context of any Regulatory Approval hereunder. The Quality Agreement shall describe in sufficient detail how the Parties intend to manage any quality-related issues likely to impact the activities to be performed under this Agreement.

3.1.3. Decision Points and Positive Results for Development Activities. The Development Plan sets forth certain decision points associated with the completion of certain clinical studies (the “Decision Points”). At each Decision Point, within [**] after the earlier of (i) [**] and (ii) [**], the JSC shall determine whether or not Positive Results have been achieved. With respect to a given Decision Point, “Positive Results” means that, based on review of [**] (in the case of clause (i)) or [**] (in the case of clause (ii)), the primary endpoint of the study was achieved (or, in the case of the Initial Data, as applicable, the cardiovascular safety results supporting the filing of a New Drug Application for Regulatory Approval consistent with applicable FDA guidance for cardiovascular safety of diabetes drugs) with overall safety and efficacy supporting continued Development or application for Regulatory Approval. If Positive Results have not been achieved, then (a) Sanofi may elect to terminate this Agreement as set forth in Section 12.3.2(i)(b) or (b) the JSC may elect to immediately discontinue or cancel all or part of any Development activities under the Development Plan that are conditioned on the achievement of Positive Results with respect to the applicable Decision Point, including any ongoing or planned clinical studies or regulatory filings, or to modify the Development Plan as it deems appropriate in good faith, in the interest of securing Regulatory Approval for a Licensed Product in the Field in the Major Markets in the Territory.

3.1.4. Diligence. Sanofi shall use Commercially Reasonable Efforts to Develop at least one LX4211 Product in the Major Markets in the Territory for T2DM as set forth in the Development Plan, but Sanofi shall not be in breach of this Section 3.1.4 to the extent that a failure to do so arises from Lexicon’s and its Affiliates’ failure to perform their respective obligations hereunder and under the Ancillary Agreements on which Sanofi’s performance depends. Lexicon shall use Commercially Reasonable Efforts to Develop at least one LX4211 Product for T1DM as set forth in the Development Plan, and, subject to the Parties’ incorporating such requirements in the Development Plan, to conduct any Required Phase 4 Studies relating to the United States and European Union Regulatory Approvals, subject to Sanofi’s and its Affiliates’ performing their respective obligations hereunder and under the Ancillary Agreements and subject to Lexicon’s right to cease such Development under Section 3.1.2(v). Each Party acknowledges and agrees that nothing in this Section 3.1.4 is intended, or shall be construed, to require the other Party to Develop more than one Licensed Product at any given time or to Develop any other Licensed Product other than the LX4211 Product.

3.1.5. Subcontracting. Each Party shall have the right to subcontract material portions of its Development activities to a Third Party (e.g., engagement of a CRO or clinical manufacturer prior to commencement of clinical activities or commercial Manufacture) (i) to the extent expressly provided for in the Development Plan or Quality Agreements, which shall set forth certain Development activities for which corresponding subcontractors have been pre-approved, or (ii) in the case that such subcontracting has not been pre-approved in the Development Plan, with the approval of the JSC, which approval shall not be unreasonably withheld, conditioned or delayed. Either Party shall have the right to subcontract to a Third Party without approval any of its Development activities to which the foregoing sentence does not apply, and for the avoidance of doubt, the foregoing sentence does not apply to general services not specific to the Licensed Products (e.g., copying and shipping).

3.1.6. Development Records. Each Party shall maintain, in good scientific manner, complete and accurate books and records pertaining to its Development activities, in sufficient detail to verify compliance with its obligations under this Agreement and which shall be appropriate for patent and regulatory purposes, in compliance with Applicable Law, including good laboratory practices, good manufacturing practices, good pharmacovigilance practices and good clinical practices, and properly reflect all work done and results achieved in the performance of its Development activities. Such books and records shall be retained by Lexicon or Sanofi, as the case maybe, for at least [**] after the expiration or termination of this Agreement in its entirety or for such longer period as may be required by Applicable Law. Each Party shall have the right, during normal business hours and upon reasonable notice, to inspect and copy all records of the other Party maintained pursuant to this Section 3.1.6; provided that the inspecting Party shall maintain such records and the information disclosed therein in confidence in accordance with ARTICLE 9.

3.1.7. Development Reports. Without limiting Section 3.1.6, on a semi-annual basis within [**] after January 1 and July 1 of each Calendar Year during the Term, each Party shall provide to the JSC or DRC, as applicable, a written report of such Development activities conducted by such Party during such Calendar Quarter. Such report shall contain reasonable detail sufficient to enable the JSC or DRC, as applicable, to assess such Party’s performance of activities pursuant to and compliance with the Development Plan, including: (i) the Party’s, or its Affiliates’ or its or their Sublicensees’ activities with respect to achieving Regulatory Approvals of such Licensed Product in the Major Markets in the Territory, (ii) clinical study results and results of other Development activities and (iii) other Development matters listed on Schedule 3.1.7. In addition, each Party shall provide the other Party with prompt notification of material developments arising in the course of Development activities conducted by such Party.

3.2. Regulatory Activities.

3.2.1. Regulatory Approvals.

(i) The Parties shall coordinate in good faith to transfer those INDs owned by Lexicon or its Affiliates relating to the Licensed Compounds or Licensed Products. To effect the foregoing, within [**] after the Effective Date, the DRC shall finalize a plan for the transfer to Sanofi or withdrawal of such INDs, which transfer shall be coordinated with the transfer of required safety and other information hereunder. Once adopted, the Parties shall use their reasonable efforts to effect the plan on the agreed upon timeline.

(ii) Except to the extent prohibited by Applicable Law or as otherwise specified herein or agreed by the DRC, all Regulatory Documentation (including all Regulatory Approvals) relating to the Licensed Compounds or Licensed Products with respect to the Territory, other than the Retained Regulatory Documentation, including any retained INDs, shall be owned by and shall be the sole property and held in the name of Sanofi or its Affiliate, Sublicensee or designee.

(iii) Effective as of the date of transfer of the applicable Regulatory Documentation (including INDs) pursuant to the agreed plan under Section 3.2.1(i), Lexicon hereby assigns to Sanofi all of its right, title and interest to such Regulatory Documentation, including all Existing Regulatory Documentation. Any Regulatory Documentation unless and until assigned pursuant to this Section shall be the “Retained Regulatory Documentation.” Once assigned to Sanofi, such Regulatory Documentation shall be deemed the “Assigned Regulatory Documentation.” Promptly following any such assignment of Regulatory Documentation, Sanofi shall grant to Lexicon such authorizations under the Assigned Regulatory Documentation necessary or desirable to enable Lexicon to perform the Development activities for which Lexicon is responsible under the Development Plan.

(iv) With regard to any assignments made or required under this Section 3.2.1, Lexicon shall duly execute and deliver or cause to be duly executed and delivered, such instruments and shall do and cause to be done such acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary under or as Sanofi may reasonably request in connection with or to carry out more effectively the purpose of or to better assure and confirm unto Sanofi its rights under this Section 3.2.1. In addition, concurrent with the assignments described in this Section 3.2.1, with respect to any IND to be transferred to Sanofi, Lexicon shall deliver to Sanofi a letter to the applicable Regulatory Authority transferring to Sanofi the applicable IND, which letters shall be mutually agreed upon by the Parties in advance of the transfer of the applicable IND.

(v) The holder of any IND or Drug Approval Application shall be considered the “Approval Holder”. The Approval Holder or its designee shall own such IND or Drug Approval Application and shall have the sole right and responsibility, at its sole expense, to make all other submissions with the Regulatory Authorities relating thereto. In the case in which Lexicon is the Approval Holder, it shall take direction from Sanofi with regard to T2DM and otherwise comply with this Agreement. Unless otherwise agreed, the Approval Holder shall have the right to conduct all meetings (subject to Section 3.2.2) and correspondence and communications with Regulatory Authorities regarding matters relating to such Drug Approval Applications as to which it is the Approval Holder. The Approval Holder shall report all Adverse Events to Regulatory Authorities if and to the extent required by Applicable Law under such Drug Approval Applications as to which it is the Approval Holder.

(vi) Lexicon shall only use any Retained Regulatory Documentation in a manner consistent with this Agreement to perform its obligations hereunder and agrees to comply with Applicable Law with respect thereto and act at the reasonable direction of Sanofi and otherwise reasonably cooperate with Sanofi in order to afford to Sanofi the benefits of such Retained Regulatory Documentation as if it were held in the name of Sanofi, including making any filings as reasonably requested by Sanofi to enable Sanofi to commence Development Activities as contemplated in the Development Plan under any Retained Regulatory Documentation.

(vii) Following, and subject to, the successful completion by the Parties of the Development activities in accordance with the Development Plan with respect to T2DM or T1DM, as the case may be, for the LX4211 Product, Sanofi shall use Commercially Reasonable Efforts to obtain

Asterisks denote omissions.

Regulatory Approval for the LX4211 Product in the Major Markets in the Territory (in the case of the European Major Markets, such Regulatory Approval may be a centralized Regulatory Approval from the European Commission) for such indication, but shall be excused from such obligation to the extent Lexicon has failed to perform its obligations hereunder and under the Ancillary Agreements upon which Sanofi is expecting to rely in connection with the applicable Sanofi activity.

(viii) Lexicon shall cooperate and support Sanofi, as may be reasonably necessary, in obtaining Regulatory Approvals for the Licensed Products and in the activities in support thereof, including providing all documents or other materials in the possession or control or Lexicon or any of its Affiliates, Lexicon CMOs or Lexicon CROs and participating in regulatory meetings at the request of Sanofi, in each case, as may be necessary or useful for Sanofi or any of its Affiliates or its or their Sublicensees to obtain Regulatory Approvals for the Licensed Products. Lexicon shall invoice Sanofi for, and Sanofi shall pay to Lexicon within [**] following any such invoice, the out-of-pocket costs and expenses incurred by Lexicon and payable to Third Parties in connection with providing any such cooperation, support or participation requested by Sanofi. For clarity, such reimbursement applies only to out-of-pocket costs incurred in connection with providing cooperation pursuant to the foregoing and not in connection with the exercise of any rights under this Agreement by Lexicon. Any such costs shall be considered Development Costs incurred by Sanofi for purposes of Section 7.6.

(ix) The Approval Holder shall provide the Party that is not the Approval Holder with a reasonable opportunity to review and comment on all major regulatory submissions and documents (i.e., INDs, Drug Approval Applications, material labeling supplements, Regulatory Authority meeting requests and core data sheets) submitted to the Regulatory Authorities in the Major Markets in the Territory (including the EMA).

(x) The Approval Holder shall consider in good faith any such comments of the other Party and otherwise act in a manner consistent with this Agreement.

(xi) Sanofi shall notify Lexicon of the filing and approval of any Drug Approval Application for a Licensed Product or major supplements or amendments thereto with or by a Regulatory Authority in a Major Market in the Territory (or the European Commission or EMA, as applicable), promptly after the filing or approval thereof.

3.2.2. Meetings with Regulatory Authorities. The Approval Holder has the right and responsibility to prepare for and lead all meetings with Regulatory Authorities regarding the Licensed Compounds and Licensed Products under the Regulatory Approvals as to which it is the Approval Holder; provided that, subject to Applicable Law, the other Party shall have the right to participate fully in all such meetings until completion of the Core Development Plan, unless such activities have been abandoned by the Parties hereunder, and, at the reasonable request of the Approval Holder, shall participate fully in all such meetings led by the Approval Holder. Except to the extent prohibited by Applicable Law, until completion of the Core Development Plan, unless such activities have been abandoned by the Parties hereunder, the Approval Holder shall afford the other Party a reasonable period of time to review and comment on all substantive communications with Regulatory Authorities by or on behalf of the Approval Holder and its Affiliates (including at such meetings and in anticipation of such meetings). Until completion of the Core Development Plan, unless such activities have been abandoned by the Parties hereunder, each Party shall notify the other Party at least [**] (or shorter if such notice period is not practicable) in advance of any meeting with Regulatory Authorities to which it becomes aware regarding the Licensed Compounds, Licensed Products or Development activities.

3.2.3. Recalls, Suspensions or Withdrawals. In the event that any government agency or authority issues or requests a recall or takes similar action in connection with the Licensed Compounds or the Licensed Products, or in the event either Party determines that an event, incident or circumstance has occurred that may result in the need for a recall or market withdrawal, the Party notified of or desiring such recall or market withdrawal shall as promptly as reasonably practical under the circumstances advise the other Party thereof. As between the Parties, Sanofi shall have the right to make the final determination whether to voluntarily implement any such recall, market suspension or market withdrawal in the Territory. If a recall, market suspension or market withdrawal is mandated by a Regulatory Authority in the Territory, as between the Parties, Sanofi shall initiate such a recall, market suspension or market withdrawal in compliance with Applicable Law. For all recalls, market suspensions or market withdrawals undertaken pursuant to this Section 3.2.3, as between the Parties, Sanofi shall be solely responsible for the execution and Lexicon shall reasonably cooperate in all such efforts. Subject to ARTICLE 11, Sanofi shall be responsible for all costs of any such recall, market suspension or market withdrawal, except to the extent that a recall, market suspension or market withdrawal resulted from Lexicon’s or its Affiliate’s breach of its obligations hereunder or under any Ancillary Agreement or from Lexicon’s or its Affiliate’s or subcontractor’s breach of this Agreement or its negligence or willful misconduct, in which case, Lexicon shall bear the expense of such recall, market suspension or market withdrawal.

3.2.4. Global Safety Database. Promptly after the Effective Date, in accordance with a plan to be established by the DRC in coordination with the transfer of Regulatory Documentation contemplated by Section 3.2.1, Lexicon shall transfer the global safety database for Licensed Products to Sanofi. Prior to such transfer, Lexicon shall bear the costs and expenses of holding and maintaining such global safety database. Following such transfer, Sanofi shall hold and maintain such global safety database (at Sanofi’s expense, except to the extent included in the Development Plan). Each Party shall provide the other Party with all information necessary or desirable for such other Party to comply with its pharmacovigilance responsibilities in the Territory, including, as applicable, any Adverse Events or other adverse drug experiences (including those events or experiences that are required to be reported to the FDA under 21 C.F.R. sections 312.32 or 314.80 or to other Regulatory Authorities under corresponding Applicable Law outside the United States), from pre-clinical or clinical laboratory, animal toxicology and pharmacology studies, clinical studies and commercial experiences with a Licensed Product, in each case in the form reasonably requested by such other Party. The Parties shall promptly negotiate, and no later than the first dosing of the first human subject in clinical studies commenced after the Execution Date for a Licensed Product for T2DM or as otherwise required by Applicable Law, enter into a reasonable and customary safety data exchange agreement (the “SDEA”), which shall describe the responsibilities and detailed procedures to be followed by the Parties with regard to all pharmacovigilance obligations to ensure safety surveillance for the Licensed Products under this Agreement.

Without limiting Sanofi’s obligations hereunder, Sanofi shall promptly notify Lexicon of any decision to cease using Commercially Reasonable Efforts to Commercialize any Licensed Product in any Major Market in the Territory. Lexicon acknowledges and agrees that nothing in this Section 4.2 is intended, or shall be construed, to require Sanofi to Commercialize more than one Licensed Product at any given time or to Commercialize any other Licensed Product other than the LX4211 Product. If Sanofi implements and uses Commercially Reasonable Efforts to carry out its responsibilities under the T1DM Commercialization Plan pursuant to Section 4.3, Sanofi shall be deemed to have satisfied its obligation to use Commercially Reasonable Efforts under this Section 4.2 and shall have no liability resulting from any failure of the activities described in the T1DM Commercialization Plan.

4.7. Leadership of T1DM Commercialization and Medical Affairs Activities in the (Co-)Promotion Territory. In the event Lexicon exercises its (Co-)Promotion Right, from and after such exercise until the expiration or earlier termination of the (Co-)Promotion Agreement, unless otherwise agreed by the Parties and subject to oversight by the JCC and the JSC and subject to the dispute resolution procedures in Section 13.5, Lexicon shall be assigned a lead role in the oversight, execution and management of (i) Commercialization activities under the T1DM Commercialization Plan other than (a) the sales and sales management efforts and (b) pricing and market access encompassed by the (Co-)Promotion Agreement and (ii) Medical Affairs Activities under the T1DM Commercialization Plan.

The JSC, DRC, MSC or JCC, as applicable, shall continue to exist until the first to occur of: (i) the Parties’ mutually agreeing to disband such committee or as otherwise set forth in this Section 5.5.6; and (ii) Lexicon providing to Sanofi written notice of its intention to withdraw from such committee (provided that Lexicon shall not have the right to withdraw prior to [**]). Upon the occurrence of any of the foregoing, (a) the applicable committee shall disband, have no further responsibilities or authority under this Agreement and will be considered dissolved by the Parties and (b) any requirement of a Party to provide Information and Inventions or other materials to such committee shall be deemed a requirement to provide such Information and Inventions or other materials to the other Party, or the JSC (in the case that the DRC, MSC or JCC is disbanded and the JSC is still in existence) and, solely in the case where the JSC has been disbanded, Sanofi shall, subject to Sections 5.5.4 and 13.5, have the right to solely decide, without consultation with Lexicon, all matters that are subject to the review or approval by the JSC hereunder other than determinations as to whether or not Positive Results have been achieved as set forth in Section 3.1.3 and Section 5.1.8, which determinations pursuant to Section 3.1.3 and Section 5.1.8 shall be resolved by binding arbitration pursuant to Section 13.5.2 if not otherwise agreed by the Parties. The MSC, DRC and JCC shall each continue to exist only for so long as the JSC is in existence; provided, however, that without limiting the foregoing, the DRC, MSC or JCC may be disbanded or discontinued at any time pursuant to a written unanimous decision of the JSC or as set forth in clauses (i) and (ii) of this Section 5.5.6. Upon disbandment of the DRC, MSC or JCC, or at any time in the JSC’s discretion, the JSC may assume from the DRC, MSC or JCC any and all of those committees respective responsibilities, and with respect to any MSC matters, any Dispute arising within the JSC shall not be resolved through the dispute resolution procedures in Section 13.5.2, but instead shall be decided by Sanofi’s JSC representatives.

Otherwise, Sanofi’s sole and exclusive remedy and Lexicon’s sole and exclusive liability to Sanofi for any nonconformity shall be for Lexicon to replace such nonconforming Licensed Compound or Licensed Product with conforming Licensed Compound or Licensed Product within reasonable timelines to be mutually agreed by the Parties in writing, but nothing in this Section 6.1.1 shall limit Lexicon’s liability for Third Party Claims under ARTICLE 11. At either Party’s option, Lexicon and Sanofi shall enter into a clinical supply agreement and a reasonable and customary Quality Agreement that shall set forth the terms and conditions upon which Lexicon and any of its Affiliates will conduct their quality activities in connection with such supply, including (i) a right of Sanofi to audit Lexicon and the Lexicon CMOs, (ii) coordination regarding inspections by Regulatory Authorities and (iii) the exchange of information between the Parties regarding the foregoing and quality issues in general. Such agreements shall be negotiated and agreed by the Parties in good faith.

6.1.2. Validation Campaign and Commercial Supply. Except as otherwise set forth in this Section 6.1, Sanofi shall have the sole right and responsibility, at its sole discretion and at its expense, to Manufacture (or have Manufactured) and supply the Licensed Products (including the Licensed Compounds contained therein) for Exploitation in or for the Territory by Sanofi and its Affiliates and its or their Sublicensees.

6.2. Manufacturing Technology Transfer. Without limiting the generality of the obligations in Section 2.4, Lexicon shall commence, as and when reasonably requested by Sanofi, the transfer to Sanofi or its designee (which designee may be an Affiliate, Sublicensee, Lexicon CMO or other Third Party manufacturer) of the Lexicon Know-How necessary or useful to perform the then-current process for the Manufacture of the Licensed Compound and Licensed Products, as well as any improvements or enhancements to such processes via a cGMP-compliant technology transfer (the “Manufacturing Process”) and provide such support as may be necessary or reasonably useful to Sanofi or its designee to use and practice the Manufacturing Process, including by (i) if permitted under the terms and conditions thereof, assigning to Sanofi, at its request, any agreements (including any open purchase orders) with Lexicon CMOs that are necessary or useful to perform Manufacturing activities related to the Licensed Compound or the Licensed Products or (ii) if such assignment is prohibited by the terms thereof or Applicable Law and if requested by Sanofi, by reasonably assisting Sanofi or its designee to enter into agreements with such Lexicon CMOs (the “Technology Transfer”). The Technology Transfer shall be conducted in accordance with reasonable timelines as mutually agreed by the Parties with the goal of completing the Technology Transfer within a reasonable time. Lexicon shall or shall cause its CMOs to allocate the necessary resources to ensure the Technology Transfer occurs in a timely and efficient manner in accordance with such deadlines. All costs and expenses of Lexicon’s internal personnel incurred by Lexicon pursuant to such Technology Transfer or any subsequent technology transfer, as provided in Section 6.3, shall be the responsibility of Lexicon, and all out-of-pocket expenses paid to Lexicon CMOs shall be the responsibility of Sanofi.

6.3. Subsequent Manufacturing Technology Transfer. Without limiting the foregoing, in the event that Lexicon or any of its Affiliates generates any material additional Lexicon Know-How relating to, or that is otherwise necessary or useful for, the Manufacture of the Licensed Compound or a Licensed Product during the Term, Lexicon shall promptly disclose such Lexicon Know-

How to Sanofi and shall, at Sanofi’s request, perform technology transfer with respect to such Lexicon Know-How in the same manner as provided in Section 6.2.

6.4. Technology Transfer Agreement. At Sanofi’s request, the Parties shall enter into a mutually acceptable Technology Transfer agreement consistent with Sections 6.2 and 6.3, which details the timeline and responsibilities of both Parties in connection with the Technology Transfer and any subsequent technology transfers from Lexicon to Sanofi during the Term (the “Technology Transfer Agreement”); provided, however, that the failure to enter into the Technology Transfer Agreement shall not relieve Lexicon of its obligations to conduct the Technology Transfers and disclosures contemplated by Sections 6.2 and 6.3.

7.3. Royalties.

7.3.1. Royalty Rates. As additional consideration for the rights granted to Sanofi hereunder and subject to the terms and conditions of this Agreement, during the applicable Royalty Term in each country of the Territory as specified below, Sanofi shall pay to Lexicon a royalty on Net Sales to Third Parties (including Distributors) of each Licensed Product in such region of the Territory during each Calendar Year within [**] after the end of each Calendar Quarter, subject to this Section 7.3, at the following rates:

(i) For T1DM in the United States:

(a) for that portion of aggregate T1DM Net Sales in the United States during a Calendar Year less than or equal to [**], a royalty rate of [**];

(b) for that portion of aggregate T1DM Net Sales in the United States during a Calendar Year greater than [**], but less than or equal to [**], a royalty rate of [**]; and

(d) for that portion of aggregate T1DM Net Sales in the United States during a Calendar Year greater than [**], a royalty rate of forty percent (40%).

Notwithstanding the foregoing, if Lexicon does not exercise the (Co-)Promotion Right in accordance with Section 4.8, enter into the (Co-)Promotion Agreement or terminates the (Co-)Promotion Agreement for convenience, the royalty rate under clause (a) of this Section 7.3.1(i) shall be [**] instead of [**].

(ii) For T2DM in the United States:

(a) for that portion of aggregate T2DM Net Sales in the United States during a Calendar Year less than or equal to [**], a royalty rate of [**];

Asterisks denote omissions.

(b) for that portion of aggregate Net Sales of all Licensed Products in the European Union during a Calendar Year greater than [**], but less than or equal to [**], a royalty rate of [**]; and

(c) for that portion of aggregate Net Sales of all Licensed Products in the European Union during a Calendar Year greater than [**], a royalty rate of [**].

(iv) For all countries in the Territory, other than the United States and those countries in the European Union (such countries, “ROW”), the royalty rate shall be [**] of aggregate Net Sales of all Licensed Products in ROW.

With respect to each Licensed Product in each country in the Territory, from and after the expiration of the Royalty Term for such Licensed Product in such country, Net Sales of such Licensed Product in such country shall be excluded for purposes of calculating the Net Sales thresholds and ceilings set forth in this Section 7.3.1.

7.3.2. Royalty Term. Sanofi shall have no obligation to pay any royalty with respect to Net Sales of any Licensed Product in any country after the Royalty Term for such Licensed Product in such country has expired.

7.3.3. Reductions. Notwithstanding the foregoing, in the event that:

(i) in any country in the Territory during the Royalty Term for a Licensed Product, one or more Generic Products of a Licensed Product is launched in such country, and Net Sales of such Licensed Product in such country decline by the percentages described below relative to the average Net Sales of such Licensed Product in such country for the [**] immediately preceding the Calendar Quarter in which the Generic Product is launched in such country (the “Pre-Generic Launch Net Sales”), the royalty rates provided in Section 7.3.1 shall be reduced in such country by the applicable percentage described below for each Calendar Quarter ending after the Generic Product was launched in which such Net Sales remain below the applicable percentage of the Pre-Generic Launch Net Sales. For clarity, the foregoing sentence shall not preclude the applicability of this Section 7.3.3(i) to future Calendar Quarters if such Generic Product or any other Generic Product is re-launched or launched, as applicable, in such country and Net Sales again fall below the applicable percentage of the Pre-Generic Launch Net Sales. For a decline of:

(a) greater than or equal to [**], but less than [**], of Net Sales of the applicable Licensed Product in such country, a royalty rate reduction of [**]; or

(b) greater than or equal to [**] of Net Sales of the applicable Licensed Product in such country, a royalty rate reduction of [**].

(ii) If Sanofi enters into an agreement with a Third Party in order to obtain a license or other right under a Third Party Patent that is reasonably necessary to avoid infringement of such Third Party Patent by the use, offer for sale, sale or importation of a Licensed Product (or the Licensed Compound contained therein) in a country pursuant to Section 8.8, Sanofi shall be entitled to deduct from any [**] royalties (under this Section 7.3) payable hereunder with respect to such Licensed Product in such country [**] of all upfront payments, milestone payments, royalties, and other amounts paid to such Third Party in respect of such agreement, in each case, to the extent reasonably allocable to such Third Party Right (“Third Party Payments”); provided that, Sanofi may not include in Third Party Payments

any amounts paid to Third Party suppliers or contract manufacturers of Licensed Products, Licensed Compounds or raw materials therefor.

(iii) If a court or a governmental agency of competent jurisdiction requires Sanofi or any of its Affiliates or its or their Sublicensees to grant a compulsory license to a Third Party permitting such Third Party to make and sell a Licensed Product in a country in the Territory, the royalties otherwise due to Lexicon pursuant to this Section 7.3 for Net Sales by compulsory licensees shall, in lieu of the royalties that would otherwise apply, be the lesser of [**] of the amount received by Sanofi from such licensee and the applicable royalties that would otherwise be payable hereunder, and the Licensed Products sold by such Third Party in such country shall be deemed to be Generic Products for purposes of Section 7.3.3(i).

(iv) As to royalties payable on Net Sales in [**], during any period within the applicable Royalty Term when there is no Lexicon Patent or Joint Patent in such country that contains a Valid Claim that Covers the applicable Licensed Product or its Manufacture, use, offer for sale, sale or importation in such country and the Regulatory Exclusivity Period has expired with respect to the applicable Licensed Product in such country, the otherwise applicable royalty rate percentage with respect to such Licensed Product in such country shall be reduced by [**].

(v) On a country-by-country basis with respect to each country in [**] during each period in which there is a [**], Sanofi shall be entitled to deduct from the royalty rate payable on Net Sales in such country [**] of the [**]; provided that such deduction shall not exceed [**]. The [**] is, with respect to a given period and country outside [**], the percentage equal to (x) [**], divided by (y) [**] in such country for such period. The [**] is, with respect to a given period, the percentage equal to [**]. For example, if the [**] for a given period and country equals [**] and the royalty rate for a given country would without application of this clause (v) equal [**], the royalty rate for such country would equal [**]. For clarity, [**] are not required to be calculated on a country-by-country basis, but may be calculated using a standard cost basis across multiple countries in accordance with Sanofi’s general internal practices.

Any reductions set forth in this Section 7.3.3 shall be applied to the royalty rate payable to Lexicon in the following order: clause (i) (in which case no further reductions shall be applied under the subsequent clauses of this Section 7.3.3), clause (ii), clause (iii), clause (iv) and clause (v).

7.3.4. Maximum Amount of Royalty Reduction. In no event shall the royalty rate payable to Lexicon under this Section 7.3 be reduced below [**] of the royalty rates set forth in Section 7.3.1 in any Calendar Year as a result of the reductions set forth in Sections 7.3.3(ii) and 7.3.3(iv), collectively.

7.4. Estimated Sales Levels. Lexicon acknowledges and agrees that the sales levels set forth in Section 7.2.2 and Section 7.3 shall not be construed as representing an estimate or projection of anticipated sales of the Licensed Products or implying any level of diligence or Commercially Reasonable Efforts, in the Territory and that the sales levels set forth in those Sections are merely intended to define Sanofi’s royalty and other payment obligations, as applicable, in the event such sales levels are achieved.

7.5. Royalty Payments and Reports. Sanofi shall calculate all amounts payable to Lexicon pursuant to Section 7.2.2 and Section 7.3 at the end of each Calendar Quarter, where Net Sales shall be converted to Dollars, in accordance with Section 7.9, and Sanofi shall provide written notice of

such amounts to Lexicon within [**] after the end of each Calendar Quarter, which report shall include a statement of (i) Net Sales, and (ii) [**] Invoiced Sales, and the applicable deductions used to convert Invoiced Sales to Net Sales, of Licensed Product in each country during the applicable Calendar Quarter. Each report shall be accompanied by the applicable payment of royalties due to Lexicon for such Calendar Quarter pursuant to Section 7.3.

7.6. Development Costs.

7.6.1. Subject to this Section 7.6, each Party shall be responsible for and shall reimburse the other Party, as applicable, for Development Costs reasonably incurred after the Effective Date in connection with the performance of Development activities in accordance with the cost-sharing principles set forth below and the Development Plan, unless otherwise agreed by the Parties and set forth in the Development Plan. To the extent FTE efforts are included in Development Costs and reimbursable by the other Party pursuant hereto, each Party shall record and account for such FTE efforts with respect to each Licensed Product, and each Party shall report such FTE efforts to the DRC on a quarterly basis. Each Party shall calculate and maintain records of FTE effort incurred by it consistent with past practice and in the same manner as used for other products developed by such Party, unless agreed by the Parties in writing. The Parties shall share Development Costs according to the following principles:

7.6.3. For so long as Development Costs are reimbursable by a Party pursuant hereto, the other Party shall report to the reimbursing Party, within [**] after the end of each Calendar Quarter (and within [**] after receipt of each such report, the Parties shall reimburse one another, as needed, for) its respective Development Costs in order to achieve the cost sharing allocation contemplated by this Section 7.6.

7.7.4. With respect to any Commercialization Costs or Medical Affairs Costs that are reimbursable by a Party pursuant hereto, the other Party shall report to the reimbursing Party, within [**] after the end of each Calendar Quarter (and within [**] after receipt of each such report, the Parties shall reimburse one another, as needed, for) its respective shared Commercialization Costs and Medical Affairs Costs in order to achieve the cost sharing allocation of such shared costs contemplated by this Section 7.7. Each such report with respect to such shared costs shall (a) allocate the Commercialization Costs and Medical Affairs Costs to the extent possible to a specific Commercialization activity or Medical Affairs Activity, as applicable, under the Commercialization Plan, (b) specify in reasonable detail all amounts included in Commercialization Costs and Medical Affairs Costs during such Calendar Quarter (broken down by activity), (c) if requested by the other Party, include copies of any invoices or other supporting documentation for any payments to a Third Party that individually exceed [**] (or such other amount approved by the JSC or JCC, as applicable) and (d) enable the other Party to compare the reported costs against the Commercialization Plan on both a quarterly basis and a cumulative basis for each activity.

Except as provided in this Section 7.11.1, Lexicon shall be solely responsible for paying any and all taxes (other than withholding taxes deducted from Payments and remitted by Sanofi as described above) levied on account of, or measured in whole or in part by reference to, any Payments it receives. Sanofi and Lexicon shall cooperate with one another to communicate in advance regarding the satisfaction of any requirements necessary to reduce the applicable rate of withholding or to relieve Sanofi of its obligation to withhold any such tax. If, in accordance with the foregoing, Sanofi withholds any amount, it shall pay to Lexicon the balance when due, make timely payment to the proper taxing authority of the withheld amount and send to Lexicon proof of such payment within [**] following such payment.

7.11.2. Value Added Tax. Notwithstanding anything contained in Section 7.11.1, this Section 7.11.2 shall apply with respect to value added tax (“VAT”). All Payments are exclusive of VAT.

At the request of the other Party, each Party shall, and shall cause its Affiliates and its and their Sublicensees (including distributors deemed to be Sublicensees under the definition of Net Sales) to, permit an independent auditor designated by the other Party and reasonably acceptable to the audited Party, at reasonable times and upon reasonable notice, to audit the books and records maintained pursuant to Section 7.13 to ensure the accuracy of all reports and payments made hereunder.

7.14.2 Such examinations may not (i) be conducted for any Calendar Quarter more than [**] after the end of such Calendar Quarter, (ii) be conducted more than [**] in any [**] (unless a previous audit during such [**] revealed an underpayment (or with respect to any reimbursement, an overpayment) with respect to such period) or (iii) be repeated for any Calendar Quarter; provided that Sanofi shall be permitted to audit Lexicon after Sanofi’s exercise of the applicable right of first negotiation pursuant to Section 2.7.1 or Section 2.7.2, as applicable, once (a) with respect to the ROFN1 Development Costs, such audit to be conducted after PoC Successful Completion, or (b) with respect to the ROFN2 Development Costs, such audit to be conducted after P3 Successful Completion.

8.5. Enforcement of Patents.

8.5.1. Notice. Each Party shall promptly notify the other Party in writing and shall provide the other Party with a copy within [**] of receipt of (i) any alleged or threatened infringement of the Lexicon Patents, Sanofi Patents or Joint Patents in any jurisdiction in the Territory or (ii) any certification filed under the Hatch-Waxman Act claiming that any Lexicon Patents, Sanofi Patents or Joint Patents are invalid or unenforceable or claiming that any Lexicon Patents, Sanofi Patents or Joint Patents would not be infringed by the making, use, offer for sale, sale or import of a product for which an application under the Hatch-Waxman Act is filed or any equivalent or similar certification or notice in any other jurisdiction in the Territory, in each case ((i) and (ii)) of which such Party becomes aware. The foregoing requirements shall apply to the Sanofi Patents solely to the extent relating to Generic Products or other products that compete with Licensed Products. Any such infringement with respect to the Lexicon Patents, Joint Patents or Sanofi Patents shall constitute an “Infringement”.

8.5.2. Enforcement of Lexicon Patents and Joint Patents. As between the Parties, Sanofi shall have the first right, but not the obligation, to prosecute any Infringement with respect to the Lexicon Patents and Joint Patents, including as a defense or counterclaim in connection with any Third Party Infringement Claim or action brought by a Third Party seeking a declaration of non-infringement of a Lexicon Patent or Joint Patent, at Sanofi’s sole cost and expense, using counsel of its own choice. In the event Sanofi prosecutes any such Infringement, Lexicon shall have the right to join as a party to such claim, suit or proceeding in the Territory and participate with its own counsel at its sole cost and expense; provided that Sanofi shall retain control of the prosecution of such claim, suit or proceeding, including the response to any defense or defense of any counterclaim raised in connection therewith. If Sanofi or its designee does not take commercially reasonable steps to prosecute an Infringement (i) within [**] following the first notice provided above with respect to such Infringement or (ii) provided such date occurs after the first such notice of such Infringement is provided, [**] before the time limit, if any, set forth in appropriate laws and regulations for filing of such actions, whichever comes first, then (x) Sanofi shall so notify Lexicon and (y) Lexicon may prosecute such alleged or threatened Infringement at its sole cost and expense.

8.5.3. Enforcement of Sanofi Patents. As between the Parties, Sanofi shall have the sole right, but not the obligation, to prosecute Infringement with respect to the Sanofi Patents, including as a defense or counterclaim in connection with any Third Party Infringement Claim, at Sanofi’s

sole cost and expense, using counsel of its own choice, and Sanofi shall retain control of the prosecution of such suit.

8.5.4. Cooperation. The Parties agree to cooperate fully in any Infringement action pursuant to this Section 8.5, including by making the inventors, applicable records and documents (including laboratory notebooks) of the relevant Patents available to the controlling Party upon the controlling Party’s request. Where a Party controls such an action, the other Party shall, and shall cause its Affiliates to, assist and cooperate with the controlling Party, as such controlling Party may reasonably request from time to time, in connection with its activities set forth in this Section 8.5, including where necessary, furnishing a power of attorney solely for such purpose or joining in, or being named as a necessary party to, such action, providing access to relevant documents and other evidence and making its employees available at reasonable business hours; provided that, except with respect to Joint Patents, the controlling Party shall reimburse such other Party for its reasonable and verifiable out-of-pocket costs and expenses incurred in connection therewith. Unless otherwise set forth herein, the Party entitled to bring any patent infringement litigation in accordance with this Section 8.5 shall have the right to settle such claim; provided that neither Party shall have the right to settle any Infringement litigation under this Section 8.5 in a manner that has a material adverse effect on the rights or interest of the other Party or in a manner that imposes any costs or liability on, or involves any admission by, the other Party, without the express written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed). In connection with any activities with respect to an Infringement action prosecuted by a Party pursuant to this Section 8.5 involving Patents Controlled by the other Party or licensed under Section 2.1 to the other Party, the Party controlling such action shall (i) consult with the other Party as to the strategy for the prosecution of such claim, suit or proceeding, (ii) consider in good faith any comments from the other Party with respect thereto and (iii) keep the other Party reasonably informed of any material steps taken and provide copies of all material documents filed, in connection with such action.

8.5.5. Recovery. Except as otherwise agreed by the Parties in connection with a separate written cost sharing arrangement, any recovery realized as a result of such litigation described above in this Section 8.5 (whether by way of settlement or otherwise) shall be first allocated to reimburse the Parties for their costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses). [**] of any remainder after such reimbursement is made shall be retained by the Party that has exercised its right to bring the enforcement action and [**] of any such remainder shall be paid to the other Party.

8.6. Invalidity or Unenforceability Defenses or Actions. Each Party shall promptly notify the other Party in writing of any alleged or threatened assertion of invalidity or unenforceability of any of the Lexicon Patents, Sanofi Patents or Joint Patents by a Third Party of which such Party becomes aware. In the event that such allegation or threatened assertion arises in connection with a proceeding covered by Section 8.5, the allocation of rights and responsibilities, including with respect to costs and recoveries, shall be governed by Section 8.5. For all other allegations or threatened assertions, the provisions of Section 8.4 shall govern the Parties’ rights and obligations with respect to such action, as if such action were a Post Grant Proceeding.

8.7. Infringement Claims by Third Parties. If the Exploitation of a Licensed Product in the Territory pursuant to this Agreement results in, or is reasonably expected to result in, any claim, suit or proceeding by a Third Party alleging infringement by Sanofi or any of its Affiliates or its or their Sublicensees, Distributors or customers (a “Third Party Infringement Claim”), including any defense or counterclaim in connection with an Infringement action initiated pursuant to Section 8.5 the Party first

becoming aware of such alleged infringement shall promptly notify the other Party thereof in writing. As between the Parties, Sanofi shall have the first right, but not the obligation, to defend and control the defense of any such claim, suit or proceeding at its sole cost and expense, using counsel of its own choice. Lexicon may participate in any such claim, suit or proceeding with counsel of its choice at its sole cost and expense. If Sanofi or its designee elects (in a written communication submitted to Lexicon within a reasonable amount of time after notice of the alleged patent infringement) not to defend or control the defense of, or otherwise fails to initiate and maintain the defense of, any such claim, suit or proceeding, within such time period so that Lexicon is not prejudiced by any delays, Lexicon may conduct and control the defense of any such claim, suit or proceeding at its sole cost and expense. Where a Party controls such an action, the other Party shall, and shall cause its Affiliates to, assist and cooperate with the controlling Party, as such controlling Party may reasonably request from time to time, in connection with its activities set forth in this Section 8.7, including where necessary, furnishing a power of attorney solely for such purpose or joining in, or being named as a necessary party to, such action, providing access to relevant documents and other evidence and making its employees available at reasonable business hours; provided that the controlling Party shall reimburse such other Party for its reasonable and verifiable out-of-pocket costs and expenses incurred in connection therewith. Each Party shall keep the other Party reasonably informed of all material developments in connection with any such claim, suit or proceeding.

8.8. Third Party Rights. Sanofi may, at its election, acquire from a Third Party any license to any Patent or other intellectual property right that it views as necessary or useful to the Exploitation of the Licensed Compound or Licensed Product by Sanofi or any of its Affiliates or any of its or their Sublicensees, Distributors or customers in order to avoid infringement or misappropriation of any Patent, trade secret or other intellectual property right of a Third Party in any country in the Territory (such right, a “Third Party Right”). In the event that Sanofi negotiates and obtains any such license that meets the criteria in Section 7.3.3(ii), then Section 7.3.3(ii) shall apply.

8.9. Product Trademarks.

8.9.1. Prosecution of Product Trademarks. Sanofi shall have the sole right to register, prosecute and maintain the Product Trademarks using counsel of its own choice. All costs and expenses of registering, prosecuting and maintaining the Product Trademarks shall be borne solely by Sanofi.

8.9.2. Enforcement of Product Trademarks. Sanofi shall have the sole right to take such action as Sanofi deems necessary against a Third Party based on any alleged, threatened or actual infringement, dilution, misappropriation or other violation of or unfair trade practices or any other like offense relating to, the Product Trademarks by a Third Party in the Territory at its sole cost and expense and using counsel of its own choice. Sanofi shall retain any damages or other amounts collected in connection therewith.

8.9.3. Third Party Claims. Sanofi shall have the sole right to defend against and settle any alleged, threatened or actual claim by a Third Party that the use or registration of the Product Trademarks in the Territory infringes, dilutes, misappropriates or otherwise violates any Trademark or other right of that Third Party or constitutes unfair trade practices or any other like offense or any other claims as may be brought by a Third Party against a Party in connection with the use of the Product Trademarks with respect to a Licensed Product in the Territory at its sole cost and expense and using counsel of its own choice. Sanofi shall retain any damages or other amounts collected in connection therewith.

Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the receiving Party unless the combination and its principles are in the public domain or in the possession of the receiving Party.

In the event that any Losses arise from (A) on the one hand, acts or omissions described in clauses (i) or (ii) of this Section 11.1 and (B) on the other hand, acts or omissions described in clauses (i) or (ii) of Section 11.2, each Party shall indemnify the other on a comparative fault basis to the extent its acts or omissions gave rise to such liability.

11.2. Indemnification of Sanofi. Lexicon shall indemnify Sanofi, its Affiliates and its and their respective directors, officers, employees and agents and defend and save each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims arising from or occurring as a result of: (i) the breach by Lexicon of this Agreement or any Ancillary Agreement; (ii) the gross negligence or willful misconduct on the part of Lexicon or its Affiliates or its or their respective directors, officers, employees or agents in performing its obligations under this Agreement or any Ancillary Agreement; or (iii) the Exploitation by Lexicon or any of its Affiliates of the Licensed Compound, Licensed Products or Terminated Products (a) anywhere in the world prior to the Effective Date or after the Term, or (b) in the Terminated Territory. In the event that any Losses arise from (A) on the one hand, acts or omissions described in clauses (i) or (ii) of this Section 11.2 and (B) on the other hand, acts or omissions described in clauses (i) or (ii) of Section 11.1, each Party shall indemnify the other on a comparative fault basis to the extent its acts or omissions gave rise to such liability.

11.3. Indemnification Procedures.

11.3.1. Notice of Claim. All indemnification claims in respect of a Party, its Affiliates or its or their respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party shall give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such indemnified Party intends to base a request for indemnification under this ARTICLE 11, but in no event shall the indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

11.3.2. Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within [**] after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party shall not be construed as an acknowledgment that the

indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 11.3.3, the indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim unless specifically requested in writing by the indemnifying Party. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against the Third Party Claim, the Indemnified Party shall reimburse the indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any Losses incurred by the indemnifying Party in its defense of the Third Party Claim.

11.3.3. Right to Participate in Defense. Any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnified Party’s sole cost and expense unless (i) the employment thereof has been specifically authorized in writing by the indemnifying Party in writing, (ii) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 11.3.2 (in which case the Indemnified Party shall control the defense) or (iii) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles.

11.3.4. Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that shall not result in any indemnitee’s becoming subject to injunctive or other relief and as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the indemnitees hereunder, the indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 11.3.2, the indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss; provided it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed). If the indemnifying Party does not assume and conduct the defense of a Third Party Claim as provided above, the Indemnified Party may defend against such Third Party Claim; provided that the Indemnified Party shall not settle any Third Party Claim without the prior written consent of the indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed).

11.3.5. Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall and shall cause each indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the

Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder and the indemnifying Party shall reimburse the Indemnified Party for all its reasonable and verifiable out-of-pocket expenses in connection therewith.

11.3.6. Expenses. Except as provided above, the costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim shall be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

11.4. Special, Indirect and Other Losses. EXCEPT (I) IN THE EVENT OF THE WILLFUL MISCONDUCT OR FRAUD OF A PARTY OR A PARTY’S BREACH OF ITS OBLIGATIONS UNDER ARTICLE 9 AND (II) TO THE EXTENT ANY SUCH DAMAGES ARE REQUIRED TO BE PAID TO A THIRD PARTY AS PART OF A CLAIM FOR WHICH A PARTY PROVIDES INDEMNIFICATION UNDER THIS ARTICLE 11, NEITHER PARTY NOR ANY OF ITS AFFILIATES OR SUBLICENSEES SHALL BE LIABLE IN CONTRACT, TORT, NEGLIGENCE, BREACH OF STATUTORY DUTY OR OTHERWISE FOR ANY CONSEQUENTIAL, INDIRECT, INCIDENTAL, SPECIAL OR PUNITIVE DAMAGES OR FOR LOSS OF PROFITS SUFFERED BY THE OTHER PARTY.

11.5. Insurance. Each Party shall have and maintain such types and amounts of insurance covering its Exploitation of the Licensed Compound and Licensed Products as is (i) normal and customary in the pharmaceutical industry generally for parties similarly situated (it being recognized that Lexicon will not be selling Licensed Products under this Agreement and, accordingly, will not carry the level of insurance that is normal and customary for commercializing parties) and (ii) otherwise required by Applicable Law. Upon request by the other Party, each Party shall provide to the other Party evidence of its insurance coverage. The insurance policies shall be under an occurrence form, but if only a claims-made form is available to a Party, then such Party shall continue to maintain such insurance after the expiration or termination of this Agreement in its entirety for a period of [**]. Notwithstanding the foregoing, Sanofi may self-insure in whole or in party the insurance requirements described above.

The Parties shall use their reasonable best efforts to respond promptly to any requests for additional information made by such agencies, and to cause the waiting period (and any extension thereof) under the HSR Act to terminate or expire at the earliest possible date after the date of filing, including by requesting early termination of the waiting period.

after the expiration or earlier termination of the waiting period (or any extension thereof) under the HSR (the date that is [**] after such expiration or earlier termination, the “Effective Date”). Subject to the foregoing sentence, upon the Effective Date the full Agreement and all its terms and provisions shall be automatically effective and binding on both Parties. If, on the [**] after the date of filing under the HSR Act the waiting period (and any extension thereof) required thereunder has not expired or been terminated, either Party shall have the right, on written notice to the other Party, to terminate this Agreement, and upon receipt of such notice by such other Party, this Agreement shall be null and void and have no further force and effect.

12.2. Term and Expiration. The term of this Agreement shall become effective as of the Effective Date and, unless earlier terminated in accordance herewith, shall continue in force and effect until the date of expiration of the last Royalty Term for the last Licensed Product (such period, the “Term”).

(iii) If Sanofi terminates this Agreement for any or no reason, whether under this Section 12.3.2 or under any other Section(s), or if Lexicon terminates this Agreement under Section 12.3.1, as to two or more Major Markets in the European Union, such termination shall constitute termination of this Agreement as to the entire European Union and thereupon the entire European Union shall become a Terminated Territory.

(iv) If Sanofi terminates this Agreement for any or no reason, whether under this Section 12.3.2 or under any other Section(s), or if Lexicon terminates this Agreement under Section 12.3.1, as to the United States and the European Union, this Agreement shall also terminate as to all other countries and thereupon such other countries shall become Terminated Territories.

12.3.3. Without limitation of the termination rights set forth above, within [**] after the Effective Date (the “Japan Decision Date”), Sanofi may terminate this Agreement with respect to Japan upon written notice to Lexicon.

12.3.5. Termination for Cessation of Development. If Sanofi ceases all actual Development and Commercialization of Licensed Products, whether or not such cessation is consistent with the exercise by Sanofi of Commercially Reasonable Efforts by Sanofi to Develop and Commercialize Licensed Products hereunder, Lexicon may terminate this Agreement upon [**] written notice to Sanofi, unless (a) Sanofi initiates a dispute resolution procedure under Section 13.5 to resolve any dispute as to whether Lexicon has the right to seek termination pursuant to this Section 12.3.5 and Sanofi is diligently pursuing such procedure, (b) the cessation of such activities results from a force majeure, Sanofi is using commercially reasonable efforts to remedy its inability to perform in accordance with Section 13.1, and such force majeure has not continued for longer than [**] or (c) the cessation of such activities constitutes a material breach under Section 12.3.1 and Sanofi is diligently pursuing an action to cure such breach for the cure period, and is otherwise following the process, set forth in Section 12.3.1.

12.5. Consequences of Termination.

12.5.1.

(iv) at Lexicon’s request, Lexicon shall assume control of all clinical studies involving Licensed Products being conducted by Sanofi as of the effective date of termination; provided that, at Lexicon’s request, except in the cases of terminations by Sanofi pursuant to Section 12.3.1 (i.e., for Lexicon’s material breach) or 12.3.4 (i.e., for Lexicon’s insolvency), Sanofi shall remain obligated to continue to fund, to the extent of Sanofi’s funding obligations under this Agreement, the costs of such clinical studies then being conducted by Sanofi for Development Costs incurred [**] after the effective date of termination;

In such case, Sanofi shall be obligated to supply quantities of such Terminated Products sufficient to satisfy Lexicon's requirements under a manufacturing transfer and transition plan to be negotiated by the Parties in good faith so that Lexicon can assume all Development and Commercialization activities with regard to such Terminated Products.

ARTICLE 13

MISCELLANEOUS

13.1. Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental authority (except to the extent such omission or delay results from the breach by the non-performing Party or any of its Affiliates of its or their Development, Manufacturing or Commercialization obligations or any other term or condition of this Agreement). The non-performing Party shall notify the other Party of such force majeure within [**] after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform. In the event that the force majeure continues for more than [**], the Party not affected by such force majeure shall have the right, at its sole election and expense, and without limitation to any other right or remedy available to such Party, to assume and complete some or all of the activities that the non-performing Party is not performing as a result of such force majeure.

13.2. Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on the Parties from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity in accordance with Applicable Law.

13.3. Assignment and Change of Control.

13.3.1. Neither Party may assign its rights or, except as expressly permitted hereunder, delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part, without the prior written consent of the other Party, except that each Party shall have the right, without such consent, to assign any or all of its rights and delegate any or all of its obligations hereunder to any of its Affiliates or its or their Sublicensees or to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of its diabetes business; provided that the assigning or delegating Party shall provide written notice to the other Party within [**] after such assignment or delegation and shall remain primarily liable for the performance of its assignee or delegate. Any permitted successor of a Party or any permitted assignee of all of a Party’s rights under this Agreement that has also assumed all of such Party’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for the assigning Party, whereupon the assigning Party shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by, and all validly delegated obligations of such Party shall be binding on and be enforceable against, the permitted successors and

assigns of such Party. Any attempted assignment or delegation in violation of this Section 13.3.1 shall be void and of no effect.

13.3.2. No later than [**] following the earlier of the first public announcement of the execution of any transaction with respect to a Change of Control of Lexicon or the closing date of such a transaction, Lexicon shall notify Sanofi in writing and identify the counterparty to the transaction (the “Third Party Acquirer”). In such a case, effective as of the later of (a) a notice from Sanofi pursuant to this Section 13.3.2 and (b) the closing of such a transaction, Sanofi shall have the following rights, except in the case of a Change of Control transaction in which the Third Party Acquirer is a Non-Competitive Acquirer:

(i) Sanofi may, in its sole discretion and by written notice to Lexicon, require Lexicon and the Third Party Acquirer and its Affiliates (“Third Party Acquirer Family”) to adopt reasonable procedures, including firewalls, to prevent disclosure of Confidential Information of Sanofi and its Affiliates (including the Sanofi Know-How) to the Third Party Acquirer Family (other than Lexicon and its Affiliates) and to prevent the Third Party Acquirer Family (other than Lexicon and its Affiliates) from involvement in the Development, Commercialization and Manufacture of the Licensed Products;

(ii) Sanofi may, in its sole discretion, assume and complete any Development activities with respect to T1DM on the Licensed Compounds. If Sanofi so elects to assume and complete any of the Development activities under the Development Plan with respect to such Licensed Compound, to the extent reasonably requested by Sanofi in writing, Lexicon shall cooperate in facilitating the orderly transfer of such Development activities and ensure that Sanofi obtains the material benefits of any or all Third Party agreements relating to such Development activities, in conformity with any Applicable Law.

(iii) Sanofi may, in its sole discretion and by written notice to Lexicon, disband the JSC (in which case the DRC and MSC shall also be disbanded) and, for clarity, Section 5.5.6 shall apply. In such a case, neither Lexicon nor any of its Affiliates shall have the right to receive Information and Inventions from Sanofi (except for reports provided pursuant to Sections 3.1.7, 4.10 and 7.5) or provide input with respect to the Exploitation of any Licensed Products from and after the date of such Change in Control (except where such input is required by Applicable Law). Notwithstanding the foregoing, this clause (iii) shall not deprive Lexicon of (A) its right to participate in discussions with Sanofi regarding the Development activities conducted pursuant to the Development Plan, Manufacturing and (Co-)Promotion, in each case, to the extent reasonably necessary in order for Lexicon to perform its obligations hereunder or under the applicable Ancillary Agreement or (B) its right to exercise a Lexicon Consent Right; or

(iv) Sanofi may, upon [**] prior written notice to Lexicon given by Sanofi not later than [**] following the Change of Control transaction, terminate the (Co-)Promotion Agreement. If Sanofi exercises its termination right under this Section 13.3.2(iii) after the commencement of (Co-)Promotion activities under the (Co-)Promotion Agreement, then Sanofi agrees to reimburse Lexicon for its reasonable wind-down costs as set forth in the (Co-)Promotion Agreement.

13.3.3. In the case in which Lexicon is acquired by a Third Party Acquirer, the rights to Information and Inventions controlled by the Third Party Acquirer Family shall, subject to Section 13.3.2(i), be automatically excluded from the rights licensed or granted to the other Party under this Agreement unless and to the extent that Lexicon uses any such Information and Inventions in the

conduct of the Development Plan or incorporates any such Information and Inventions into any Licensed Product.

13.4. Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (i) such provision shall be fully severable, (ii) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (iii) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and (iv) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid or unenforceable in any respect.

13.5. Dispute Resolution.

13.5.1. Subject to Section 13.10, if a dispute arises (i) within the JSC with respect to any decision under the jurisdiction of the JSC that remains unresolved pursuant to Section 5.5.3 (a “JSC Dispute”) or (ii) between the Parties in connection with or relating to this Agreement or any Ancillary Agreement (collectively, (i) and (ii), a “Dispute”), then either Party shall have the right, upon notice to the other Party, to refer such Dispute to the Senior Officers for attempted resolution by good faith negotiations during the period of [**] following the date of such referral. Any final decision mutually agreed to by the Senior Officers shall be conclusive and binding on the Parties. If such Senior Officers are unable to resolve any such JSC Dispute within such [**] period, Sanofi shall have the right to finally and definitively resolve any Dispute in good faith in a manner consistent with this Agreement unless (a) there is a Lexicon Consent Right with respect to the matter (in the case of clause (a), such Disputes shall be resolved only by the mutual written consent of the Parties), (b) the matter is outside the jurisdiction and authority of the JSC (including as set forth in Section 5.5.4), (c) the Dispute is a Legal Dispute, or (d) the subject matter of the Dispute is whether Positive Results have been achieved in all material respects with respect to any Decision Point (in the case of clause (d), such Dispute shall be resolved, if not resolved by negotiations by the Senior Officers in accordance with this Section 13.5.1 above, by binding arbitration pursuant to Section 13.5.2). With respect to any unresolved dispute as to a matter outside the jurisdiction and authority of the JSC or Legal Dispute, either Party shall be free to institute binding arbitration in accordance with Section 13.5.2 upon written notice to the other Party (an “Arbitration Notice”) and seek such remedies as may be available. Notwithstanding anything in this Agreement to the contrary, either Party shall be entitled to institute litigation in accordance with Section 13.6 immediately with respect to any dispute as to a matter outside the jurisdiction and authority of the JSC or Legal Dispute if litigation is necessary to prevent irreparable harm to that Party.

13.5.2. Upon receipt of an Arbitration Notice by a Party, the applicable Dispute shall be resolved by final and binding arbitration before a panel of three (3) arbitrators with relevant biopharmaceutical industry experience (the “Arbitrators”), who shall be selected in accordance with the Comprehensive Arbitration Rules and Procedures then in effect and the Expedited Procedures contained therein, as modified in this paragraph (the “Rules”). Such arbitration shall be administered by JAMS (or any successor entity thereto) and in accordance with the Rules, except (i) to the extent such rules are inconsistent with this Section 13.5.2, in which case, this Section 13.5.2 shall control (including with regard to any limitations of liability or forms of relief), and (ii) three (3) discovery depositions may be

conducted per side. The JAMS Expedited Procedures shall be modified to delete paragraphs 16.2(b) (Limitation on Document Requests) and 16.2(e) (Limitation on Expert Depositions) of such procedures as in effect on the Effective Date, and the timelines shall be modified to provide that (x) the discovery cutoff for percipient discovery shall not exceed [**] after the preliminary conference, (y) the discovery cutoff for expert discovery shall not exceed [**] after the preliminary conference, and (z) the hearing shall commence within [**] after the cutoff for expert discovery. The proceedings and decisions of the arbitrators shall be confidential, final and binding on the Parties, and judgment upon the award of such arbitrator may be entered in any court having jurisdiction thereof. The arbitration shall be conducted in English and held in New York, New York. The Arbitrator shall, within [**] after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The decision or award rendered by the Arbitrator shall be final and non-appealable, and judgment may be entered upon it in accordance with Applicable Law in the State of New York or any other court of competent jurisdiction. The Arbitrator shall be authorized to award compensatory damages, but shall not be authorized to reform, modify or materially change this Agreement or any Ancillary Agreement. Each Party shall bear its own counsel fees, costs, and disbursements arising out of the arbitration described in this Section 13.5.2, and shall pay an equal share of the fees and costs of the Arbitrator and all other general fees related to the arbitration; provided, however, the Arbitrator shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable counsel fees, costs and disbursements (including expert witness fees and expenses, photocopy charges, or travel expenses), or the fees and costs of the Arbitrator. Unless the Parties otherwise agree in writing, during the period of time that any arbitration proceeding is pending under this Agreement, the Parties shall continue to comply with all those terms and provisions of this Agreement that are not the subject of the pending arbitration proceeding. Nothing contained in this Agreement shall deny any Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing arbitration proceeding. All arbitration proceedings and decisions of the Arbitrator under this Section 13.5.2 shall be deemed Confidential Information of both Parties under Article 9. The Parties intend that each award rendered by an Arbitrator hereunder shall be entitled to recognition and enforcement under the United Nations Convention on the Recognition and Enforcement of Arbitral Awards (New York, 1958).

13.6. Governing Law, Jurisdiction, Venue and Service.

13.6.1. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. The Parties agree to exclude the application to this Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

13.6.2. Jurisdiction. Subject to Section 13.5 and Section 13.10, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts of the State of New York for any action arising out of or relating to this Agreement and agree not to commence any action, suit or proceeding (other than appeals and enforcements of awards therefrom) related thereto except in such courts. The Parties irrevocably and unconditionally waive their right to a jury trial in any such action.

13.6.3. Venue. Subject to Section 13.5 and Section 13.10, the Parties further hereby irrevocably and unconditionally waive any objection to the laying of venue of any action arising out of or

PRESS RELEASE

Sanofi and Lexicon Pharmaceuticals to Collaborate on Sotagliflozin, an Investigational New Oral Medicine for People with Diabetes

Paris and The Woodlands, TX - November 6, 2015 - Sanofi (EURONEXT: SAN and NYSE: SNY) and Lexicon Pharmaceuticals, Inc. (NASDAQ: LXRX) announced today that they have entered into a collaboration and license agreement for the development and commercialization of sotagliflozin, an investigational new oral dual inhibitor of sodium-glucose cotransporters 1 and 2 (SGLT-1 and SGLT-2), which could be a potential treatment option for people with diabetes.

“This agreement with Lexicon reinforces our commitment to helping people living with diabetes,” said Pascale Witz, Executive Vice President, Sanofi, who will lead the Global Diabetes and Cardiovascular Care Business Unit in the company's new organizational structure. “Adding sotagliflozin to our portfolio, which includes medicines at virtually every stage of the treatment pathway, highlights our focus on providing a large and diverse set of therapeutic options for people with this disease.”

The developmental medicine sotagliflozin (LX4211) is currently being studied in two pivotal Phase 3 trials in type 1 diabetes, which are expected to report top-line results during the second half of 2016. Phase 3 trials in type 2 diabetes are expected to begin in 2016. Sotagliflozin has previously shown encouraging results in exploratory (Phase 2) studies, including reduction of blood sugar (HbA_1c), improvement in glycemic variability and reduced meal-time insulin dose compared with placebo in type 1 diabetics. Phase 2 studies exploring treatment in people with type 2 diabetes, including those with renal impairment, showed lowering of blood sugar (HbA_1c), weight loss and blood pressure improvements. No increase in hypoglycemic events was seen with sotagliflozin compared to background therapy in the Phase 2 program. The adverse event profile in the Phase 2 program was similar to other products in this class and reflective of the urinary glucose excretion associated with sotagliflozin’s inhibition of SGLT-2.

These results indicate that sotagliflozin could have the potential to become an important option among oral anti-diabetic medicines and provide a strong rationale for the further investigation of this compound as a treatment for people with diabetes.

“Lexicon firmly believes in the potential of sotagliflozin for patients living with diabetes. It has been our strategy to focus our resources on the development of sotagliflozin for type 1 diabetes and to pursue a strategic partnership with respect to type 2 diabetes only if it would strengthen stakeholder value under a fully integrated diabetes program. We believe this arrangement with Sanofi achieves that objective,” said Lexicon President and Chief Executive Officer Lonnel Coats. “Sanofi's patient-centric focus in diabetes, and its rich history of innovation in diabetes, make it an exceedingly attractive partner which is well positioned to unlock the full potential of sotagliflozin for patients living with diabetes. Also consistent with our strategy, Lexicon will continue to lead the development of sotagliflozin for type 1 diabetes and have rights to participate in the commercialization of sotagliflozin for type 1 diabetes in the United States.”

with the Securities and Exchange Commission.

Asterisks denote omissions.

Under the terms of the agreement, Lexicon will receive an upfront payment of $300 million and is eligible to receive development, regulatory and sales milestone payments of up to $1.4 billion. Lexicon is also entitled to tiered, escalating double digit percentage royalties on net sales of sotagliflozin.

Sanofi obtains an exclusive worldwide license to develop, manufacture and commercialize sotagliflozin. Lexicon will continue to be responsible for all clinical development activities relating to type 1 diabetes and will retain an exclusive option to co-promote and have a significant role, in collaboration with Sanofi, in the commercialization of sotagliflozin for the treatment of type 1 diabetes in the United States. Sanofi will be responsible for all clinical development and commercialization activities of sotagliflozin for the treatment of type 2 diabetes worldwide and will be solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the United States. Lexicon will share in the funding of a portion of the planned type 2 diabetes development costs over the next three years, up to an aggregate of $100 million.

The agreement is subject to customary filing and review under the Hart-Scott-Rodino Antitrust Improvements Act.

The investigational agent described above is currently under clinical development and its safety and efficacy have not been evaluated by any regulatory authority.

Item 1.01	Entry into a Material Definitive Agreement.

On November ___, 2015, we entered into a Collaboration and License Agreement (the “Agreement”) with Sanofi for the worldwide development and commercialization of our diabetes drug candidate sotagliflozin.

Under the Agreement, we granted Sanofi an exclusive, worldwide, royalty-bearing right and license under our patent rights and know-how to develop, manufacture and commercialize sotagliflozin. Subject to specified exceptions, neither party may (a) perform clinical development activities relating to any other compound which inhibits sodium-glucose cotransporters type 1 or type 2 or (b) commercialize any such compounds in the United States, countries of the European Union and certain other specified countries, in each case during the royalty terms applicable in such countries. Among the specified exceptions is a right we retained to pursue the development of our LX2761 drug candidate, with respect to which we granted Sanofi certain rights of first negotiation specified in the Agreement.

Under the Agreement, Sanofi will pay us an upfront payment of $300 million. In addition, we are eligible to receive from Sanofi (a) up to an aggregate of $430 million upon the achievement of specified development and regulatory milestones and (b) up to an aggregate of $990 million upon the achievement of specified sales milestones. We are also entitled to tiered, escalating royalties ranging from low double digit percentages to forty percent of net sales of sotagliflozin, based on indication and territory, with royalties for the higher band of such range attributable to net sales for type 1 diabetes in the United States, and subject in each case to customary royalty reduction provisions. Royalties payable with respect to net sales of sotagliflozin for type 1 diabetes in the United States will also be reduced in the event we do not exercise our co-promotion option described below.

We will continue to be responsible for all clinical development activities relating to type 1 diabetes and will retain an exclusive option to co-promote and have a significant role, in collaboration with Sanofi, in the commercialization of sotagliflozin for the treatment of type 1 diabetes in the United States. If we exercise our co-promotion option, we will fund forty percent of the commercialization costs relating to such co-promotion activities. Sanofi will be responsible for all clinical development and commercialization of sotagliflozin for the treatment of type 2 diabetes worldwide and will be solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the United States. We will share in the funding of a portion of the planned type 2 diabetes development costs over the next three years, up to an aggregate of $100 million. Sanofi will book sales worldwide in all indications.

The parties are responsible for using commercially reasonable efforts to perform their development and commercialization obligations pursuant to mutually approved development and commercialization plans.

The parties’ activities under the Agreement are governed by a joint steering committee and certain other governance committees which reflect equal or other appropriate representation from both parties. If the applicable governance committee is not able to make a decision by consensus and the parties are not able to resolve the issue through escalation to specified senior executive officers of the parties, then Sanofi will have final decision-making authority, subject to limitations specified in the Agreement.

The Agreement will expire upon the expiration of all applicable royalty terms for all licensed products in all countries. The royalty term for each licensed product in each country is the period commencing on the effective date of the Agreement and ending on the latest of expiration of specified patent coverage, expiration of specified regulatory exclusivity and 10 years following the first commercial sale in the applicable country. Either party may terminate the Agreement in the event of an uncured material breach by the other party. Prior to completion of the core development activities for type 2 diabetes specified in the development plan, Sanofi may terminate the Agreement on a country-by-country and licensed product-by-licensed product basis, in the event of (a) notification of a material safety issue relating to the licensed product or the class of sodium-glucose cotransporters type 1 or type 2 inhibitors resulting in a recommendation or requirement that we or Sanofi cease development, (b) failure to achieve positive results with respect to certain clinical trial results, (c) the occurrence of specified fundamental adverse events or (d) the exploitation of the

licensed product infringing third party intellectual property rights in specified major markets and Sanofi is unable to obtain a license to such third party intellectual property rights.

The effectiveness of the Agreement is contingent upon satisfaction of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

We issued a press release announcing the Agreement on November 6, 2015, a copy of which is attached to this current report on Form 8-K as Exhibit 99.1.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the Agreement, which we expect to file as an exhibit to our annual report on Form 10-K for the year ending December 31, 2015.
