The transfer of Product by Reata or one of its Affiliates or (sub)licensees to another Affiliate or (sub)licensee shall not be considered a Net Sale, unless any such (sub)licensee is the end user of the Product.

If such average sale price cannot be determined for the stand-alone Products or the other products, Net Sales for the purposes of determining royalty payments shall be mutually agreed upon by the Parties based on the relative value contributed by each component.

Notwithstanding the foregoing, in the event that the Selling Party is any party other than Reata or its Affiliates, then Net Sales (including Combination Product allocations in connection with such Net Sales) will be calculated based on the corresponding definition of net sales in the applicable license agreement permitting such sales, provided that such definition is commercially reasonable, but subject to challenge by BXLS pursuant to Section 6.8.

Each Party initially will appoint [***] representatives to serve as representatives to the AC (the “AC Representatives”), with each AC Representative having knowledge and expertise regarding developing products similar to the Product and sufficient decision-making authority within the applicable Party to make decisions on behalf of such Party within the scope of the AC’s decision‑making authority and, if any such representative is not an employee of the appointing Party, such representative shall execute a confidentiality agreement in form and substance acceptable to the other Party (and, for the avoidance of doubt, the appointing Party shall remain responsible to the other Party for any noncompliance by such representative with such confidentiality obligations). Each Party may replace its AC Representatives at any time upon written notice to the other Party.

5.1.2Chairperson. The AC chairperson (“AC Chairperson”) shall be designated from the Parties’ AC Representatives and shall serve for a term of [***]. BXLS shall appoint the first AC Chairperson and subsequent appointments will rotate on an annual basis between Reata and BXLS.

5.1.3Meetings. From the Closing Date, through the date of the Approval in both the US and the EU5, the AC will meet at least once per Calendar Quarter (and for clarity, such meetings are intended to be conducted via teleconference) unless the Parties mutually agree otherwise.

5.1.4Participants; Voting. The AC may invite individuals who are not AC Representatives to participate in AC meetings; provided that (a) [***] of both Parties consent to such non-member’s participation; and (b) such non-member has executed a confidentiality

agreement in form and substance acceptable to the non-inviting Party (and, for the avoidance of doubt, the inviting Party shall remain responsible to the non-inviting Party for any noncompliance by such individual with such confidentiality obligations). For clarity, such non-members will have no voting rights at the AC.

5.1.5Alliance Managers. Each Party shall appoint an individual to act as an alliance manager for such Party (each, an “Alliance Manager”) by providing the name and contact information for the Alliance Manager to the AC. Each Party may change its Alliance Manager from time to time in its sole discretion upon written notice to the other Party. The Alliance Managers shall be the primary point of contact for the Parties regarding the activities contemplated by the Agreement, and the Parties shall use reasonable efforts to ensure that any requests for information and data made outside of the AC are made through the Alliance Mangers. The Alliance Managers shall attend all meetings of the AC. For clarity, the Alliance Managers may also be members of the AC.

5.1.6Costs of AC. Each Party will bear its own expenses relating to the meetings and activities of the AC.

5.2AC Responsibilities and Decision-Making .

5.2.1Responsibilities (Review and Discuss). Other than to the extent specifically set forth in Sections 5.2.2 and 5.2.3, the AC is not a decision-making body, but rather an advisory and informational body. The AC’s core responsibilities will include reviewing and discussing (but not approving) the following:

5.2.1.1the conduct of the Development Program, including (i) overall strategic direction, (ii) developing strategies to maximize the value of the Product for the treatment of the Core Indications, and (iii) reviewing and commenting on the Clinical Study Plan and Commercialization Plans;

5.2.1.2material changes in the Development Program that do not require approval pursuant to Sections 5.2.2 or 5.2.3 below, including material changes that are required by, or made to respond to comments from, a Regulatory Authority;

5.2.1.3Clinical Update Summary and Commercialization Update Summary;

5.2.1.4Prior to and following completion of the Development Program, updates regarding material Development plans or events for the Product in any Core Indication other than ALPS or ADPKD.

5.2.1.5Reata’s forecast of the estimated timeline (on at least a quarterly basis) for Commercial Launch with respect to the Product for the Core Indications; or

5.2.1.6any other matters the Parties mutually agree will be, or are expressly provided in this Agreement to be, reviewed and discussed by the AC.

5.2.2Responsibilities (Review and Approve). The AC shall be tasked with discussing and approving (in each case, such approval not to be unreasonably withheld, conditioned or delayed): (i) the Timeline Remediation Plan as set forth in Section 5.2.2.1 below, provided that such approval rights set forth in Section 5.2.2.1 shall lapse on [***], and (ii) material changes to the Development Plan as and to the extent set forth in Section 5.2.3; provided, that such approval rights set forth in Section 5.2.3 shall lapse upon [***], or as otherwise set forth in Section 5.2.3, as applicable.

5.2.2.1Timeline Remediation Plan. If Reata fails to, or reasonably knows that it will not, complete a Trial Activity within the specified Timeline for such Trial Activity, Reata will promptly notify the AC, and, unless the AC’s approval rights have lapsed pursuant to Section 5.2.2, then: if Reata has failed to, or knows that it will not, complete (a) any Trial Activity within [***] of the expected Timeline for such Trial Activity, or (b) the final Trial Activity set forth in the Clinical Development Plan within [***] of the Timeline for such final Trial Activity, then, in either case of (a)-(b), Reata will provide the AC with a written remediation plan detailing the means by which, and a target date by which, Reata expects to be able to complete the relevant Trial Activities (each, a “Timeline Remediation Plan”). Following receipt thereof, the AC Representatives will discuss and consider in good faith such Timeline Remediation Plan, and if the AC approves such Timeline Remediation Plan (such approval not to be unreasonably withheld, conditioned or delayed), the AC will provide Reata with written notice thereof. Reata will use Commercially Reasonable Efforts to carry out the activities set forth in the Timeline Remediation Plan, and Reata will be required to update the AC of its progress with respect thereto. If the AC does not approve the Timeline Remediation Plan, then BXLS’s representatives on the AC shall (i) provide a written justification to Reata for such refusal and (ii) propose an alternate timeline remediation plan setting forth the means by which, and a target date by which, it expects Reata to be able to complete the relevant Trial Activities (the “Alternate Remediation Proposal”). The Parties shall negotiate in good faith for a period of [***], and if the Parties cannot agree on a final Timeline Remediation Plan, then either Party may refer the matter for final resolution pursuant to Section 5.2.2.2.

5.2.2.2Expedited Resolution by Independent Expert. If the AC does not approve a Timeline Remediation Plan or the Alternate Remediation Proposal, and the Parties are unable to reach mutual agreement within the period specified in the last sentence of Section 5.2.2.1, then, upon the written request of either Party, the determination of whether to approve the initially proposed Timeline Remediation Plan or the proposed Alternate Remediation Proposal shall be referred to an independent Third Party expert in the field of drug development and commercialization who is (i) acceptable to both Parties or (ii) if the Parties fail to agree on an independent Third Party expert in accordance with the preceding clause (i), an independent Third Party expert in the field of drug development and commercialization selected by the ICC International Centre for ADR in accordance with the Rules for the Appointment of Experts and Neutrals of the International Chamber of Commerce (the “Independent Expert”). The sole authority of the Independent Expert will be to (A) set a schedule for expedited dispute resolution, (B) request supporting documentation from each Party with respect to their proposed Timeline Remediation Plan or Alternate Remediation Proposal, as applicable, and (C) select, on the basis of which plan is more reasonable (taking into account the Parties respective rights and obligations under this Agreement and their rights in and to the Product and the Net Sales thereof (including

the right to receive the Product Payments)) either the (1) the Timeline Remediation Plan or (2) the Alternate Remediation Proposal in its entirety (i.e. the Independent Expert shall not be able to select any middle ground proposal). Unless otherwise agreed by the Parties, the Independent Expert’s determination shall be final and binding upon the Parties and Reata will be obligated to perform the tasks set forth in the selected plan, and use Commercially Reasonable Efforts to complete such tasks in accordance with the timelines set forth therein. Unless otherwise agreed by the Parties, the Independent Expert shall be required to make his or her determination within [***] after his or her selection as the Independent Expert. The Party who’s plan is not selected shall pay the costs of the Independent Expert.

5.2.3BXLS Approval. Until such time as Reata shall [***], the approval of the AC Representatives of BXLS (such approval not to be unreasonably withheld or delayed) shall be required (a) in connection with any change in the Development Program that would materially decrease the likelihood of obtaining or materially increase the timeline for obtaining an Approval in the US or the EU5 and that is either (i) a change to the lead Indication of a Product Trial; or (ii) a change to any primary endpoint of the Product Trials as set forth in the Clinical Study Plan, in either case of (i) and (ii) where such change is not required by, or made to respond to comments from, a Regulatory Authority, and (b) the addition of any new Clinical Trial by Reata that is reasonably likely to result in a Serious Safety Issue that would significantly reduce the likelihood of Approval or result in a drug product label that would significantly reduce the commercial potential of the Product, provided that such approval shall not be required for a Clinical Trial seeking Approval for [***] Indications, unless such Clinical Trial would utilize safety exclusion criteria less restrictive from those set forth on Exhibit G-1, with respect to [***], or Exhibit G-2 with respect to [***], and provided that the Protocol for such Clinical Trial has been accepted by the FDA, EMA, or the Pharmaceuticals and Medical Devices Agency (PMDA). In the event that Reata shall [***], such approval shall not be required with regard to any change to the Development Program that applies specifically with regard to obtaining Approval in such country.

5.2.4Limitation on Authority. Notwithstanding anything to the contrary set forth in this Agreement, the AC will have no authority to (x) amend, modify or waive compliance with this Agreement, (y) resolve any dispute concerning the validity, interpretation, construction of, or breach of this Agreement or (z) require that either Party take any action (or refrain from taking any action) that would cause it to breach any agreement to which such Party is a party as of the Closing Date or cause such Party to be in violation of Applicable Law.

5.2.5Decision-Making. Reata shall retain sole decision-making authority over all matters within the scope of the AC’s oversight other than the matters described in the foregoing Section 5.2.2 and 5.2.3. The unanimous approval of the AC will be required with respect to all matters within its decision-making authority as described in the foregoing Section 5.2.2. The AC Representatives of each Party will collectively have one (1) vote (with the result that each Party (rather than the individual AC Representatives) has one vote). If the AC cannot reach consensus on any matter for which approval is required under Section 5.2.3, then neither party shall have the final decision-making authority, and absent agreement at the AC, the status quo shall persist with respect to such matter, subject to Section 5.2.4.

5.2.6Disbandment of the AC. The AC will terminate immediately at Reata’s option upon delivery of written notice by Reata to BXLS, provided that such dissolution notice may only be provided following the occurrence of any of the following: (i) [***], (ii) the date that Cumulative Payments equal [***]% of the BXLS Development Payment or (iii) any assignment transfer or sale by BXLS of all or substantially all of its rights to receive payments under this Agreement to any party other than an Affiliate of BXLS (including any Change of Control of BXLS). Upon the termination of the AC, the AC will thereafter have no further authority or meetings with respect to the activities hereunder, and Reata shall not have any additional obligations to provide information to the AC, but for clarity, shall continue to provide all Product Payment reports, as required pursuant to Section 6.5.

Article 6

PAYMENTS TO BXLS

6.1Tiered Bardoxolone Payments. Subject to the remainder of this Section 6.1, Reata will pay to BXLS the following Royalty Percentage of aggregate Calendar Quarter worldwide Net Sales of the Product as follows:

6.1.1Provided that the BXLS Development Payment has been made, following the receipt of Initial Approval, Reata will pay to BXLS [***]% of Net Sales of the Product until (a) if the Product does not receive Approval for ADPKD in the United States on or before [***] (in which case Section 6.1.2 shall apply following such date), or (b) if the Product does receive Approval for ADPKD in the United States on or before [***], the date that Cumulative Payments equal [***]% of the BXLS Development Payment. Solely in the case that subsection (b) applies, following the date that Cumulative Payments equal [***]% of the BXLS Development Payment, Reata will pay to BXLS a lower royalty of [***]% of Net Sales of the Product (as opposed to [***]% of such Net Sales) in perpetuity for so long as the Product is being sold by or on behalf of Reata or its Affiliates (for the avoidance of doubt, with a BXLS Development Payment of $[***], the Royalty Stepdown will occur when Product Payments reach an aggregate of $[***]).

6.1.2If the Product has received Initial Approval, but does not receive Approval for ADPKD in the United States on or before [***], then commencing on [***], and continuing until December 31, 2033, Reata will pay to BXLS [***]% of Net Sales of the Product (in lieu of any payment pursuant to Section 6.1.1); provided that if, at any point during the period commencing with the Calendar Quarter ending [***] and ending with the Calendar Quarter ending [***], the aggregate Net Sales of the Product during any [***] consecutive Calendar Quarters exceeds $[***], the Royalty Percentage shall be decreased to [***]% of Net Sales (as opposed to [***]% of such Net Sales) commencing on the first day of the next Calendar Quarter (for example, if the threshold has been met as of [***], such decrease shall take effect as of [***]). For the avoidance of doubt, (i) such adjustment shall not be applicable if the Product has been Approved for ADPKD in the United States on or before [***] and (ii) there shall never be an instance where payments are owed under both Section 6.1.1 and Section 6.1.2 with respect to the Net Sales of the Product. For purposes of determining whether the aggregate Net Sales during any [***] consecutive Calendar Quarters exceeds $[***] and for purposes of determining Net Sales of the Calendar Year [***], Net Sales shall exclude any sales of the Product which result in wholesalers, distributors or other

members of Reata’s distribution channel that purchase directly from Reata or its Subsidiaries holding in the aggregate more than a [***]supply of product based on average Net Sales during the preceding [***] Calendar Quarters, provided that any such excess Net Sales amount shall be applied to following Calendar Quarter.

6.1.3Following the receipt of the Approval, if, at the end of each Calendar Year commencing with 2025 and through the end of Calendar Year 2033, Cumulative Payments as of the end of such Calendar Year (which for purposes of this Section 6.1.3 shall include Product Payments that are due but not yet payable pursuant to Section 6.4 but only to the extent such Product Payments are paid within the timeframe specified in Section 6.4), would for any reason result in BXLS receiving less than the Cumulative Minimum Payment Target for such Calendar Year, then, subject to each Condition Precedent, which are to be applied and tested separately with respect to each potential Cumulative Minimum Payment Target each Calendar Year, Reata will pay BXLS an additional amount (which shall in no event be less than zero) equal to (a) the Cumulative Minimum Payment Target as of the end of such Calendar Year, minus (b) Cumulative Payments as of the end of such Calendar Year (such amounts to be calculated, for the avoidance of doubt, after giving effect to any payments made pursuant to Sections 6.1.1 or 6.1.2 and any payments due but not yet payable under Section 6.6 in respect of such Calendar Year). For the avoidance of doubt, the requirements of this Section 6.1.3 shall not apply prior to the Approval.

6.2Product Payment True-Up. Upon written request by BXLS made within [***] after the end of any Calendar Year after Initial Approval Reata will perform a “true-up” reconciliation within [***] after the end of such Calendar Year (and provide BXLS with a written report of such reconciliation) of the deductions outlined in the definition of Net Sales. The reconciliation will be based on the actual cash paid or credits issued in such Calendar Year relative to the accrued amounts (if any) of such deductions used to calculate Net Sales for such Calendar Year. If such reconciliation report shows either an underpayment or overpayment of Product Payments the Party owing payment to the other Party will pay the amount of such difference to the other Party within [***] of the date of delivery of such report.

6.3Product Payment Assignment. BXLS will not have the right to sell or assign its rights under this Agreement or the Product Payments to a Third Party at any time prior to the earlier of (i) [***] months after the Approval and (ii) [***]. At any time after the earlier of (i) [***] months after the Approval and (ii) [***], BXLS will have the have the right to sell or assign the Product Payments to a Third Party, by providing Reata written notice of its intention to do so. Reata will have the right to notify BXLS of the price it is willing to pay to purchase the Product Payment (the “Proposed Buyout Payment”) within [***] after receiving such notice from BXLS. If BXLS accepts the Proposed Buyout Payment, Reata shall purchase the Product Payments from BXLS in exchange for the Proposed Buyout Payment. If BXLS does not so accept such offer within [***] of receipt of such notice, BXLS will be free (but shall not be required) to sell or assign the Product Payments to a Third Party within [***] ([***]) days from the expiration of the foregoing [***] period at a price higher than the Proposed Buyout Payment.

6.4Payments; Prepayments. From and after the Initial Approval, Reata shall make the payments required pursuant to Sections 6.1.1 and 6.1.2 on a quarterly basis no later than [***] after the end of each Calendar Quarter and the payments required pursuant to Section 6.1.3 on an

annual basis no later than [***] after the end of the applicable Calendar Year; provided that in Reata’s sole election, it may make any such payments on a more frequent basis. Reata shall not be entitled to make prepayments in respect of future Product Payments not yet due.

6.5Product Payment Reports and Records Retention. Reata shall deliver to BXLS, together with the applicable Product Payment (as set forth in Section 6.4 above), a written report setting forth in reasonable detail, the calculation of the Product Payment payable and identifying (i) each Selling Party, (ii) the foreign currency exchange rates used, and (iii) a break-down of all permitted deductions from gross sales used to determine Net Sales and the Product Payment due to BXLS. For [***] (unless Reata’s internal company procedures for its Affiliate require a shorter period) after each sale, transfer or other disposition of the Product, Reata will keep (and will obligate its Affiliates, and any Selling Party to keep) complete and accurate records in sufficient detail to confirm the accuracy and completeness of the Net Sales of the Products made by such Selling Party. Reata will retain such records for [***] after the earlier of expiration or early termination of this Agreement.

6.6Change of Control of Reata. In the event of a Change of Control of Reata prior to January 1, 2026, Reata will pay to BXLS a fully creditable amount equal to (i) [***] % of the BXLS Development Payment if the Change of Control occurs prior to [***] after the Effective Date, or (ii) [***]% of the BXLS Development Payment if the Change of Control occurs [***] after the Effective Date or later (either such payment a “CoC Advance Payment”), in each case within sixty (60) days of the date of Change in Control, which CoC Advance Payment, in either case, will be fully creditable toward any future Product Payments. Reata (including for the avoidance of doubt its successor in such Change of Control): (a) shall be obligated to continue to exercise Commercially Reasonable Effort to develop the Product and seek Approval as set forth herein following the date of such Change in Control, and (b) shall remain obligated to pay any Product Payments that become due and payable pursuant to Article 6 at such time as such Product Payments become due and payable (if ever) pursuant to Article 6, provided that such Product Payments shall be reduced by the amount previously paid to BXLS and credited toward such Product Payments as set forth in this Section 6.6. For clarity, there shall be no amounts payable under this Section 6.6 in the event of a Change of Control of Reata following January 1, 2026.

6.7Late Payments. All payments due and payable to a Party under this Agreement will earn interest from the date due until paid at a per annum rate equal to the lesser of (a) the maximum rate permissible under Applicable Law and (b) [***]% per annum. Interest will be calculated on the basis of a 360-day year. The payment of such interest will not limit the Parties from exercising any other rights at their disposal as a consequence of any late payments.

6.8Financial Audits. Following Commercial Launch for the Product, upon at least fourteen (14) Business Days written notice and during normal business hours, no more frequently than once per calendar year, BXLS may cause an inspection and/or audit by an independent public accounting firm reasonably acceptable to Reata to be made of Reata’s books of account for the three (3) calendar years prior to the audit for the purpose of determining the correctness of Product Payments made under this Agreement. Upon BXLS’s reasonable request not more than once in any calendar year while any Third Party License remains in effect, Reata shall exercise any rights it may have under any Third Party License to cause an inspection and/or audit by an independent

public accounting firm to be made of the books of account of any counterparty thereto for the purpose of determining the correctness of Product Payments made under this Agreement and promptly provide BXLS with the results of such inspection and/or audit. and Reata shall include in any such Third Party License provisions allowing Reata (or an independent public accounting firm) reasonable and customary rights to inspect and audit the relevant books of account of such counterparty consistent in scope with the rights granted to BXLS hereunder with respect to Reata’s books and records. All of the expenses of any inspection or audit requested by BXLS hereunder (including the fees and expenses of such independent public accounting firm designated for such purpose) shall be borne by (i) the BXLS, if the independent public accounting firm determines that Product Payments previously paid were incorrect by an amount less than or equal to [***]% of the Product Payments actually paid or (ii) Reata, if the independent public accounting firm determines that Product Payments previously paid were incorrect by an amount greater than [***]% of the Product Payments actually paid. The terms on which any such independent public accounting firm is engaged shall provide that such independent public accounting firm may not disclose the confidential information of Reata or any such counterparty to any Third Party License to BXLS, except to the extent such disclosure is either necessary to determine the correctness of Product Payments or such confidential information otherwise would be included in a Product Payment report provided pursuant to Section 6.5. All information obtained by BXLS as a result of any such inspection or audit shall be Confidential Information of Reata and the independent public accounting firm shall be considered a Representative of BXLS for purposes of Article 10. Absent manifest error, the financial results of the audit of the independent public accounting firm will be final and non-appealable. Any payment owed by one Party to another as a result of the audit shall be made within [***] of receipt of the audit report. Without limiting the foregoing, Reata shall, on the request of BXLS, provide BXLS with a copy of the Net Sales provision under any Third Party License and supporting financial data provided to Reata that is being used to determine the Product Payments payable to BXLS, and if BXLS so desires it may challenge whether such provision is commercially reasonable in accordance with the dispute resolution process set forth in Section 15.10.

6.9Methods of Payment and Currency.

6.9.1Unless otherwise expressly agreed in writing by the Parties, all payments owed to BXLS or Reata hereunder shall be made by deposit of US Dollars to such United States bank account as BXLS or Reata, as applicable, may from time to time designate by written notice to the other Party. The Parties may vary the method of payment set forth herein at any time by written agreement, and any change shall be consistent with Applicable Law at the place of payment or remittance.

6.9.2With respect to Net Sales not denominated in US Dollars, Net Sales in foreign currency will be converted into US Dollars by using the then-current and reasonable standard exchange rate methodology applied to Reata’s external reporting.

6.10Taxes. Each Party represents and warrants that it is a “United States person” within the meaning of Section 7701(a)(30) of the IRS (a “U.S. Person”). Based on the foregoing representation, the Parties hereby acknowledge and agree that no withholding or similar taxes are required to be deducted or withheld from any payment made under this Agreement, unless (a) such

withholding or similar tax becomes payable due to the assignment of this Agreement or any payment obligation hereunder (to the extent permitted) by either Party to an Affiliate or Third Party, the re-domiciling of either Party outside the US or any other circumstance that results in such Party no longer being a U.S. Person, (b) there is a change in Applicable Laws at any time during the Term such that withholding or other additional taxes may be imposed or levied on account of the payment of any amounts under this Agreement or (c) a Party receiving payments under this Agreement (the “Recipient Party”) fails to provide the other Party (the “Withholding Party”) or its agent with an executed IRS Form W-9 certifying that the Recipient Party is a U.S. Person and is exempt from U.S. federal backup withholding tax. If a Withholding Party is required to withhold any taxes on any amounts payable to the Recipient Party hereunder, the Withholding Party shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as are required to be deducted and withheld under Applicable Laws with respect to the making of such payment; provided, that if the requirement to deduct or withhold is due to the Withholding Party (or its Affiliate) having taken any of the actions described in clause (a) of this Section 6.10, then the amount payable to the Recipient Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 6.10), the Recipient Party shall have received an amount equal to the sum it would have received had no such deduction or withholding been made. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. The Parties agree to cooperate in good faith and use their respective reasonable efforts to reduce or eliminate, to the extent permitted under Applicable Laws, any withholding or similar taxes on account of or in respect of any payments hereunder (including through the provisions of tax forms as described in Section 6.11).

6.11Tax Cooperation. The Parties will cooperate and produce on a timely basis any tax forms or reports, including any IRS Forms W-8BEN, W-8BEN-E or W-9, as applicable, reasonably requested by the other Party in connection with any payment made under this Agreement. Each Party will provide to the other Party any other tax forms that may be reasonably necessary in order for such Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide, upon request, to the other Party any tax forms at least thirty (30) days prior to the due date for any such payments; provided that such request for such forms was made in a timely manner. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT. Each Party will provide commercially reasonable cooperation to the other Party, at the other Party’s expense, in connection with any official or unofficial tax audit or contest relating to tax payments made with respect to amounts paid or payable to such other Party under this Agreement.

In connection with the entry by Reata into any Permitted Priority Debt from and after the Initial Approval or any Senior Refinancing Debt, the Parties shall enter into an intercreditor

agreement with any new lender(s) on terms and conditions reasonably acceptable to BLXS and Reata, providing for the subordination of the Reata Obligations to such Permitted Priority Debt or Senior Refinancing Debt; provided, however, that such intercreditor agreement shall provide that any Liens securing such Permitted Priority Debt or Senior Refinancing Debt, as applicable, shall (a) for the avoidance of doubt not include the BXLS Collateral Account Assets, and (b) be junior in priority to BXLS’s Liens on the Bardoxolone IP Proceeds Collateral; provided further, that for the purposes of establishing the aggregate amount of any Reata Obligations in any intercreditor agreement pursuant to Section 7.4, the aggregate amount of Reata Obligations at any time shall not exceed amount equal to [***]% of the BXLS Development Payment, less Cumulative Payments as of such time.

The provisions of this Section 7.6.1.1(b) shall not apply to Excluded Accounts and for the avoidance of doubt shall terminate upon Approval.

10.2.2.1to its Representatives, in each case as reasonably required in connection with the performance of this Agreement, provided that (a) each Person receiving Confidential Information must be bound by obligations of confidentiality and non-use at least as stringent as an equivalent in scope to those set forth in this Article 10 prior to any such disclosure (or with respect to professional service providers, that are bound by customary and reasonable obligations of confidentiality and non-use (including under any ethical or professional standards)) prior to any such disclosure; and (b) the Party making such disclosure to such Person shall be liable to the other Party for any breach of such obligations by such disclosee (provided that a Party’s Representative(s) shall only be bound by the obligations set forth in this Article 10 to the extent that such Representative(s) actually receives such Confidential Information);

Except as otherwise provided herein, upon expiration or earlier termination of this Agreement, all Confidential Information (including any copies thereof) in written or other tangible form will, at the Disclosing Party’s direction, be returned to the Disclosing Party or destroyed by the Receiving Party, and any Person(s) to whom the Receiving Party disclosed (with such destruction being confirmed in writing by an authorized officer of the Receiving Party), except (i) to the extent such Confidential Information is necessary to exercise any license and/or rights hereunder that survive such expiration or earlier termination; and (ii) one (1) copy of each document may be retained by the Receiving Party solely to the extent necessary to permit it to comply with any ongoing rights and responsibilities with respect to such Confidential Information.

11.1.2Arising IP. The Parties do not contemplate or anticipate the development or generation of any intellectual property by the Parties in connection with their activities under this Agreement. Without limiting the foregoing, and except as expressly set forth in this Section 11.1.2, (a) each Party shall solely own any idea, discovery, method, technique, know-how, or other intellectual property developed or generated solely by or on behalf of such Party in the course of such Party’s performance under this Agreement, and (b) the Parties shall jointly own any idea, discovery, method, technique, know-how, or other intellectual property developed or generated jointly by both Parties in the course of performing activities under this Agreement and each Party shall have full rights to license, assign and exploit such jointly owned

Article 12

INDEMNIFICATION AND INSURANCE

12.1Indemnification by Each Party.

12.1.1By BXLS. BXLS will indemnify and hold Reata; its Affiliates and its and their respective officers, directors, employees and agents (the “Reata Indemnified Parties”), harmless from any and all Losses arising or resulting from any Claims by a Third Party against any Reata Indemnified Parties to the extent arising from (a) BXLS’s gross negligence or willful misconduct in performing its obligations under this Agreement; and/or (b) BXLS’s material breach of this Agreement; provided that the foregoing shall not subject BXLS to liability for lost revenue, profits or other consequential damages of Reata or its Affiliates, and further provided that BXLS shall not have any responsibility for a Claim to the extent that any of the foregoing (a) through (b) were caused by any Reata Indemnified Party or Permitted Third Parties’ gross negligence, willful misconduct, or material breach of this Agreement.

12.1.2By Reata. Reata will indemnify and hold BXLS, its Affiliates, BXLS’s investors and its and their respective members, officers, directors, employees and agents (the “BXLS Indemnified Parties”), harmless from any and all Losses arising or resulting from any Claims by a Third Party against any BXLS Indemnified Parties to the extent arising from (a) a Product; (b) injuries sustained by Subjects in connection with the Product Trials, including Claims arising prior to the Effective Date, based upon physical injury or death of a Subject in connection with the Product Trials (including a personal injury or death of a Subject that is caused by the Subject’s participation in the Product Trials whether or not directly attributable to the Product), or from the Commercialization of the Product; (c) Reata’s gross negligence or willful misconduct in performing its obligations under this Agreement including in the conduct of the Product Trials or preparation and submission of the information for Approval; or (d) Reata’s breach of this Agreement, provided that the foregoing shall not subject Reata to liability for lost revenue, profits, or other consequential damages of BXLS or its Affiliates; (e) any Permitted Third Party’s material breach of the Protocol, (f) actual or alleged infringement of any Third Party’s Intellectual Property by the Product or by Reata in performing activities hereunder; (g) any breach by Reata of Section 11.4; and further provided that Reata shall not have any responsibility for a Claim to the extent that any of the foregoing (a) through (g) were caused by any BXLS Indemnified Party’s gross negligence, willful misconduct, or material breach of this Agreement.

12.2Indemnification Procedure.

12.2.1Notice of Claim. A Party believing that it is entitled to indemnification under Section 12.1.1 or 12.1.2 (an “Indemnified Party”) will give prompt written notice (each,

an “Indemnification Claim Notice”) to the other Party (the “Indemnifying Party”) of commencement of any Claim for which indemnification may be sought, or if earlier, upon the assertion of any such Claim by a Third Party (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a Claim of a Third Party as provided in this Section 12.2.1 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give notice). The Indemnified Party will furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses.

12.2.2Control of Defense. At its option, the Indemnifying Party may assume the defense of any 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 Claim by the Indemnifying Party will not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify the Indemnified Party in respect of the Claim, nor will 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 Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Claim any legal counsel selected by the Indemnifying Party and approved by the Indemnified Party, such approval not to be unreasonably withheld. Without limiting the Indemnified Party’s other obligations under Section 12.2, in the event the Indemnifying Party assumes the defense of a Claim, the Indemnified Party will promptly deliver to the Indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Claim. Should the Indemnifying Party assume the defense of a Claim, the Indemnifying Party will 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 such Claim.

12.2.3Right to Participate in Defense. Without limiting Section 12.2.2, the Indemnified Party will be entitled to (a) participate in, but not control, the defense of such Claim and to engage counsel of its choice for such purpose; provided, however, that such engagement will be at the Indemnified Party’s own expense unless the engagement thereof has been specifically authorized by the Indemnifying Party in writing, and (b) control its defense of such Claim and to engage counsel of its choice for such purpose, at the expense of the Indemnifying Party, if the Indemnifying Party has failed to assume the defense and engage counsel in accordance with Section 12.2.2.

12.2.4Settlement. With respect to any Losses related solely to payment of money damages in connection with a Claim that (a) includes a complete and unconditional release of the Indemnified Party, (b) will not result in the Indemnified Party admitting liability, becoming subject to injunctive or other equitable relief that will otherwise adversely affect the business of the Indemnified Party in any manner, and (c) as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the Indemnifying Party will 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, will deem appropriate. With respect to all other Losses in connection with Claims, where the Indemnifying Party has assumed the defense of the Claim in accordance with Section 12.2.2, the Indemnifying Party will 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 will not be unreasonably withheld, conditioned or delayed). The Indemnifying Party will not be liable for any settlement or other disposition of a Loss by the Indemnified Party that is reached without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will not admit any liability with respect to, or settle, compromise or discharge, any Claim without the prior written consent of the Indemnifying Party, not to be unreasonably withheld or delayed.

12.2.5Cooperation. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will reasonably cooperate in the defense or prosecution thereof and will 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 will 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 Claim, and making employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

12.3Insurance.

12.3.1Generally. Commencing as of the Closing Date and thereafter during the Term, and subject to Section 12.3.2 below, Reata will carry and maintain, at its own expense, insurance coverage of the kind and with liability limits that, at a minimum, satisfy the requirements of Section 12.3.2, to protect itself and BXLS against any claims or liabilities that may arise from the conduct of the Product Trials and all other rights and obligations hereunder with insurers with a minimum “A-” A.M. Best rating (except for Lloyds of London, which is not rated). Any deductibles for such insurance policies will be assumed by Reata. Such insurance policies will be primary and non-contributing with respect to any other similar insurance policies available to BXLS or its Affiliates. Prior to the Closing Date, and annually, at each anniversary of the Closing Date (unless, during such year, expiration of the applicable policy occurs first, in which case, on such expiration date), at BXLS’s written request Reata will provide BXLS with documentation of such insurance coverage via original certificates of insurance, if applicable. Reata will provide BXLS a minimum of [***] prior written notice to BXLS if it is unable to obtain appropriate insurance coverage or if its coverage is canceled, unable to be renewed or materially changed. For clarity, failure to maintain adequate insurance coverage does not relieve or reduce Reata’s liability under this Agreement. Reata will ensure that no subcontractor, including any Permitted Third Party, will continue to perform the work unless such subcontractor is insured as deemed appropriate by the Party engaging the Permitted Third Party.

12.3.2Minimum Requirements. Commencing as of the start of the Product Trials and thereafter, during the Term (or longer if otherwise stated below), at a minimum, Reata, will maintain the following types of insurance coverage at a minimum level that is the greater of (a) the highest minimum level required by Applicable Law in the countries in which the Product

Trials and other obligations hereunder are being performed or (b) the following (to the extent different):

12.3.2.1Commercial General Liability: [***] dollars ($[***]) per occurrence; [***] dollars ($[***]) Product and Completed Operations aggregate, including Premises & Operations, Personal Injury, Product and Completed Operations; [***] ($[***]) combined single limit on all owned, non-owned and hired vehicles of Reata.

12.3.2.2Umbrella Excess Liability: [***] dollars ($[***]) per occurrence.

12.3.2.3Clinical Trial Liability: [***] dollars ($[***]) per occurrence. Coverage must be maintained for at least [***] after the later of termination of this Agreement or release of the last Subject from the Product Trials.

12.3.3Additional Insured. Reata will include BXLS and its Affiliates as additional insured parties on Reata’s Clinical Trials Liability insurance, as set forth in Section 12.3.2.3, for the duration of the Product Trials and for five (5) years after the later of termination of this Agreement or release of the last Subject from the Product Trials.

12.3.4Product Liability Insurance. Reata will be responsible for maintaining product liability insurance related to the Commercialization of the Product at its expense.

In the event that this Agreement terminates pursuant to Section 14.2.4 above prior to receipt of the Approval and such termination (i) arises as a result of gross negligence on the part of Reata, or (ii) is due to the applicable independent data monitoring committee recommending termination of the Product Trials or Reata and BXLS mutually agreeing to terminate the Product Trials, in either case due to a Serious Safety Issue that was previously known by Reata as being material as of the Effective Date and such

Serious Safety Issue was not included in the Data Room or otherwise disclosed in writing to BXLS by Reata prior to the Effective Date, then (A) Reata will pay BXLS a fully creditable amount equal to [***]% of BXLS Development Payment, less Cumulative Payments as of such time, within [***] of the date of termination, and (B) if Reata elects to continue Development and obtains Approval following such termination, Reata will remain obligated to pay any Product Payments that become due and payable pursuant to Article 6 at such time as such Product Payments become due and payable (if ever) pursuant to Article 6, provided any amounts paid by Reata to BXLS pursuant to this Section 14.3.4 shall be fully credited toward the future Product Payments.

14.3.5Accrued Rights and Obligations. Expiration or termination of this Agreement for any reason will not release either Party from any obligation or liability which, at the time of such expiration or termination, has already accrued to the other Party or which is attributable to a period prior to such expiration or termination. Notwithstanding anything to the contrary in this Agreement (including without limitation any provisions in Article 7 or the definition of “BXLS Security Period”), any security interests in favor of BXLS on any BXLS Collateral that have not yet then terminated shall survive any termination with respect to any unpaid obligations under Section 6.1, Section 6.2, Section 6.6, Section 6.7 or this Section 14.3, in each case, that have accrued and are then payable.

14.3.6Not Exclusive Remedy. Notwithstanding anything herein to the contrary, termination of this Agreement by a Party will be without prejudice to other remedies such Party may have at law or equity.

14.3.7Surviving Obligations. Expiration or earlier termination of this Agreement will not relieve either Party of any obligation accruing prior to or upon such expiration or earlier termination, including that neither Party will be relieved of any payment obligation that may have accrued prior to such expiration or earlier termination. Further, other than in the case of a termination pursuant to Section 14.2.5, the following provisions of this Agreement, together with any other provisions that expressly specify that they survive, will survive expiration or earlier termination of this Agreement: Sections 6.1.1, 6.1.2, 6.1.3 (solely to the extent specified in Section 14.3.1 or Section 14.3.4), 6.2, 6.3 (but only the first two sentences thereof) 6.4, 6.5, 6.7, 6.8, 6.9, 6.10 and 6.11 (in each case solely to the extent the obligation to make Product Payments survives pursuant to this Article 14), Sections 7.2, 7.3, and 7.6 (in each case solely to the extent a security interest in favor of BXLS on any BXLS Collateral survives pursuant to Section 14.3.5), Section 7.7, Sections 12.1 and 12.2, Article 1, Article 10, Article 11, Article 14 and Article 15.

14.3.8Termination for Failure to Close or by Mutual Agreement. In the event that this Agreement is terminated pursuant to Section 14.2.5 or 14.2.6 above, then, Reata shall not be obligated to make any payments to BXLS pursuant to Section 6 or otherwise, all security interest shall be terminated and released; provided that the following provisions of this Agreement, will survive expiration or earlier termination of this Agreement pursuant to Section 14.2.5, Section 7.7, Article 1, Article 10, Article 11, Article 14 and Article 15 (other than Section 15.6).

Notwithstanding the foregoing, BXLS and Blackstone may use the name, logos, and other insignia of Reata in any “tombstone” or other advertisements, in its publications, marketing or promotional materials to existing and prospective investors and otherwise on the website or in other marketing materials of BXLS and/or Blackstone, as applicable, without Reata’s prior approval.

Notwithstanding the foregoing, any assignment of the rights or obligations under this Agreement by Reata (i) to an Affiliate shall require Reata to guarantee the performance of such Affiliate’s financial and performance obligations hereunder or (ii) in connection with a sale of assets, merger, consolidation, or Change of Control (other than other than as set forth in clause (b) of its definition) of Reata without the consent of BXLS, such consent not to be unreasonably withheld, delayed or conditioned, shall require (x) the ultimate Affiliate controlling the other party in such transaction to guarantee Reata’s financial and performance obligations under this Agreement and (y) Reata to remain liable for such financial and performance obligations notwithstanding such sale of assets, merger, consolidation, or Change in Control. Furthermore, notwithstanding any of the foregoing, on or after the Closing Date BXLS may (a) assign its right to receive Product Payments to (i) the limited partners of BXLS, provided that such limited partners agree that a majority in interest shall be entitled to take all actions and make any consents on behalf of BXLS hereunder and provided that such limited partners notify Reata of a single account to which Reata can make all payments that may become due hereunder and assume sole responsibility for distributing all such payments, or to a liquidating trust or similar entity that is established to receive and distribute Product Payments for the benefit of the limited partners of BXLS, that is required to carry out such responsibilities as a single entity, and provided that such limited partners or liquidating trust takes such rights to receive and distribute Product Payments subject to all of Reata’s rights and defenses hereunder (and in any case under this clause (i) Reata shall have the unconditional right to follow any instruction it receives or rely on any actions, consents and communications received from or taken by such limited partners or liquidating trust or similar entity without any duty to verify or otherwise determine the validity thereof) or (ii) an other Third Party to which BXLS assigns this Agreement in its entirety as set forth above, or assigns its right to receive Product Payments, in each case as provided in, and subject to, Section 6.3 provided that, following any assignment by BXLS to a Third Party pursuant to the foregoing clause (ii) the AC shall terminate, such assignee shall not have any further rights under Article 5 and such assignee shall not have any further rights to approve or consent (and Reata shall not have any further obligation to seek BXLS’s approval or consent) as to any matter relating to Reata’s Development and Commercialization of the Product and, provided that such assignment complied with the terms of Section 6.3, Section 6.5 shall not apply to such Third Party, and (b) assign its right to receive up to [***] of the Product Payments to an Affiliate provided that BXLS shall retain the sole right to take all actions and make any consents on behalf of BXLS hereunder and that all Product Payments made to such Affiliate shall be deemed to be made to BXLS for all purposes of this Agreement. This Agreement is binding upon and will inure to the benefit of each of the Parties, its successors and permitted assigns.

15.7Further Assurances. The Parties will execute such further reasonable documents and perform such further reasonable acts as may be necessary to comply with or more fully effectuate the terms of this Agreement.

15.8Fees and Expenses. Reata will be responsible for paying the reasonable legal and administrative expenses of BXLS on the Closing Date and reimbursing BXLS for the same, including reasonable fees and expenses incurred by BXLS in connection with the preparation and negotiation of transaction documents for the diligence investigation, and legal counsel to BXLS. In addition, Reata shall pay all expenses associated with, and have all rights to, the commercial/revenue assessment conducted by an outside consultancy (e.g., [***]) engaged by BXLS prior to the date hereof. Notwithstanding the foregoing, Reata’s obligation to reimburse and pay any reasonable legal fees, administrative expenses and other amounts pursuant to this Section 15.8 shall not exceed an aggregate amount of $[***].

15.9Governing Law. The construction and validity of this Agreement and the provisions hereof, and the rights and obligations of the Parties hereunder, will be governed by the internal laws of the State of New York, and, to the extent applicable to Patents and Trademarks, the applicable federal laws of the USA, in each instance without regard to conflict of laws principles.

15.10Dispute Resolution. The Parties recognize that disputes as to certain matters arising out of and relating to this Agreement may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes in an expedient manner by mutual cooperation and without resort to litigation. Accordingly, the Parties agree that any dispute, controversy or claim arising under, out of, relating to or in connection with this Agreement, including any subsequent amendments, or the formation, applicability, validity, enforceability, construction, performance, breach or termination hereof (and including the scope and applicability of this Section 15.10 to any such dispute, controversy or claim) (each a “Dispute”) shall be resolved by the Parties as follows:

15.10.1Prior to commencing an arbitration, a Party shall first refer such Dispute to the Executive Officers for attempted resolution by good faith negotiations during a period of [***] running from the date the notice of Dispute is received. Any final decision mutually agreed to by the Executive Officers in writing shall be conclusive and binding on the Parties. With respect to any Dispute that is not resolved after the [***] period expires, then such Dispute shall be submitted to the American Arbitration Association (“AAA”) for final and binding arbitration pursuant as set forth in Section 15.10.2 in accordance with its Commercial Arbitration Rules then in force. Notwithstanding the foregoing, disputes relating to the ownership of any intellectual property by the Parties in connection with their activities under this Agreement, if any, including disputes relating to the validity or enforceability thereof, shall be resolved by a US federal court of appropriate jurisdiction and not through arbitration. Any question about whether a dispute is arbitrable shall be decided by the arbitrators. Notwithstanding anything in this Agreement to the contrary, either Party shall be entitled to seek preliminary injunctive relief in any court of competent jurisdiction immediately if necessary to prevent irreparable harm to that Party.

15.10.2Arbitration Process.

15.10.2.1Either Party shall have the right to initiate arbitration at any time after the expiration of [***] after receipt of the notice of Dispute as set forth in Section 15.10.1 by filing a written demand for arbitration. Any disputes concerning whether a dispute is arbitrable,

or whether any conditions precedent to commencing arbitration have been fulfilled or the thirty-day period has expired, shall be finally settled by the arbitral panel. Notwithstanding the foregoing, any dispute between the Parties as to whether entering into a Licensing Transaction would have a Material Impact shall be resolved as set forth in Section 15.10.

15.10.2.2The seat, or legal place of arbitration, shall be New York City, New York, and the language of the proceedings shall be English. The arbitration shall be before three (3) arbitrators. Within [***] after the commencement of the arbitration, each Party shall select one arbitrator and the two (2) Party-selected arbitrators shall select the third, who shall serve as the panel’s chair or president, within [***] after the second arbitrator’s appointment. Any arbitrator(s) not timely selected shall by selected by the American Arbitration Association. All three (3) arbitrators shall be professionals with substantial experience in development and Commercialization of biopharmaceutical products. An arbitrator shall be deemed to meet these qualifications unless a Party objects within [***] after the arbitrator is selected. The Parties acknowledge that this Agreement evidence a transaction involving interstate commerce. Notwithstanding the provision in Section 15.9 with respect to the applicable substantive law, any arbitration conducted under this Agreement shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16.

15.10.2.3Consistent with the expedited nature of arbitration, each Party will, upon the written request of the other Party, [***] of the preliminary hearing or such other date as established at the preliminary hearing, provide the other with copies of documents on which the producing Party intends to rely in support of or in opposition to any claim or defense. At the request of a Party, the arbitrators shall have the discretion to order examination by deposition if the arbitrators deem such additional discovery relevant and appropriate. Depositions shall be limited to a maximum of [***] per Party. Each deposition shall be limited to seven hours on the record. The arbitrators shall also have the discretion to allow requests for production of documents, upon a showing of good cause. No other discovery shall be allowed. Any Dispute regarding discovery, or the relevance or scope thereof, shall be determined by the arbitrators, which determination shall be conclusive. All discovery shall be completed within [***] following the appointment of the arbitrators. All costs and/or fees relating to the retrieval, review and production of electronic discovery shall be paid by the Party requesting such discovery.

15.10.2.4The arbitrators will have no authority to award punitive or other damages not measured by the prevailing Party’s actual damages. Each Party expressly waives and foregoes any right to consequential, punitive, special, exemplary or similar damages or lost profits. The arbitrators shall have no power or authority, under the AAA Commercial Arbitration Rules and procedures or otherwise, to relieve the Parties from their agreement hereunder to arbitrate or otherwise to amend or disregard any provision of this Agreement. The arbitrators shall award to the prevailing party of all of its reasonable arbitration costs and fees. Costs and fees mean all reasonable pre-award expenses of the arbitration, including the arbitrators’ fees, administrative fees, out-of-pocket expenses, witness fees and attorneys’ fees.

15.10.2.5The arbitrators shall render a reasoned award. If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of [***] dollars USD ($[***]), then the arbitral award shall be final and binding and the

Parties undertake to carry out any award without delay. Judgment on that award may be entered in any court of competent jurisdiction. In the event that the arbitration does result in an arbitral award that imposes an injunction or a monetary award in excess of [***] dollars USD ($[***]), the Parties agree that such award may be appealed pursuant to the AAA’s Optional Appellate Arbitration Rules (“Appellate Rules”) and shall not be considered final until after the time for filing the notice of appeal pursuant to the Appellate Rules has expired. Appeals must be initiated within [***] of receipt of the award by filing a Notice of Appeal with any AAA office. Following the appeal process, the decision rendered by the appeal tribunal may be entered in any court of competent jurisdiction.

15.10.2.6Except as may be required by law, to protect or pursue a legal right, or enforce or challenge an award in bona fide legal proceedings before a state court or other judicial authority, neither a Party nor an arbitrator may disclose the existence, contents, or any rulings or awards of any arbitration hereunder without the prior written consent of both Parties except to the extent necessary for the preparation or presentation of a claim or defense in the arbitration, where such information is already in the public domain other than as a result of a breach of this clause, or by order of the arbitrators upon application of a Party.

15.11Limitation of Liability. TO THE MAXIMUM EXTENT PERMITTED BY LAW AND NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, NEITHER PARTY WILL BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, RELIANCE OR PUNITIVE DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCTS LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE. THE PARTIES AGREE THAT THE LIMITATIONS SPECIFIED IN THIS SECTION WILL APPLY EVEN IF ANY LIMITED REMEDY SPECIFIED IN THIS AGREEMENT IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, “CONSEQUENTIAL DAMAGES” WILL BE DEEMED TO INCLUDE, AND NEITHER PARTY WILL BE LIABLE TO THE OTHER PARTY OR ANY OF SUCH OTHER PARTY’S AFFILIATES, REPRESENTATIVES OR STOCKHOLDERS FOR ANY DAMAGES BASED ON OR MEASURED BY LOSS OF PROJECTED OR SPECULATIVE FUTURE SALES OF THE PRODUCT, ANY PAYMENT DUE UPON ANY UNACHIEVED EVENT UNDER ARTICLE 6, OR ANY OTHER UNEARNED, SPECULATIVE OR OTHERWISE CONTINGENT PAYMENTS PROVIDED FOR IN THIS AGREEMENT. FOR THE AVOIDANCE OF DOUBT, THIS SECTION 15.11 IS NOT MEANT TO LIMIT REATA’S OBLIGATION TO PAY BXLS THE AMOUNTS SET FORTH IN ARTICLE 6 OR SECTION 14.3.

15.12Cumulative Remedies. Unless expressly set forth in this Agreement, all rights and remedies of the Parties, including all rights to payment, rights of termination, rights to injunctive relief, and other rights provided under this Agreement, will be cumulative and in addition to all other remedies provided for in this Agreement, in law, and in equity.

15.13Relationship of the Parties.

15.13.1Relationship of the Parties. Nothing contained herein will be deemed to create a partnership, joint venture, or similar relationship between the Parties, including for any applicable Tax purposes. Neither Party is the agent, employee, joint venturer, partner, franchisee, or representative of the other Party. Each Party specifically acknowledges that it does not have the authority to, and will not, incur any obligations or responsibilities on behalf of the other Party. Notwithstanding anything to the contrary in this Agreement, each Party (and its officers, directors, agents, employees, and members) will not hold themselves out as employees, agents, representatives, or franchisees of the other Party or enter into any agreements on such Party’s behalf.

15.13.2Direction. Neither Party will be subject to the supervisory direction of the other Party in regard to the conduct of the Product Trials.

15.15Rights Reserved. No license or any other right is granted to either Party, by implication or otherwise, except as specifically set forth in this Agreement. All rights not exclusively granted to BXLS are reserved to Reata and its Affiliates. Notwithstanding any other provision of this Agreement to the contrary, and for clarity, no Intellectual Property or other proprietary rights Controlled by Reata or its Affiliates will be assigned or licensed to BXLS in connection with this Agreement.

15.16Amendments; No Waiver. Unless otherwise specified herein, no amendment, supplement, or modification of this Agreement will be binding on either Party unless it is in writing and signed by both Parties. No delay or failure on the part of a Party in the exercise of any right under this Agreement or available at law or equity will be construed as a waiver of such right, nor will any single or partial exercise thereof preclude any other exercise thereof. All waivers must be in writing and signed by the Party against whom the waiver is to be effective. Any such waiver will constitute a waiver only with respect to the specific matter described in such writing and will in no way impair the rights of the Party granting such waiver in any other respect or at any other time.

15.17Severability. If any provision (or portion thereof) of this Agreement is determined by a court or arbitration to be unenforceable as drafted by virtue of the scope, duration, extent, or character of any obligation contained herein, it is the Parties’ intention that such provision (or portion thereof) will be construed in a manner designed to effectuate the purposes of such provision to the maximum extent enforceable under such Applicable Law. The Parties will enter into whatever amendment to this Agreement as may be necessary to effectuate such purposes.

15.18Entire Agreement. This Agreement, including all Exhibits hereto, contains the entire understanding of the Parties and supersedes, revokes, terminates, and cancels any and all other arrangements, understandings, agreements, term sheets, or representations and warranties, whether oral or written, between the Parties relating to the subject matter of this Agreement.

15.19Counterparts. This Agreement will be executed in two (2) counterparts, one (1) for either Party, which, taken together, will constitute one and the same agreement. This Agreement will not be binding on the Parties or otherwise effective unless and until executed by both Parties.

15.20Construction. This Agreement has been negotiated by the Parties and their respective counsel. This Agreement will not be construed in favor of or against either Party by reason of the authorship of any provisions hereof.
