Notwithstanding the foregoing or any other provision of this Agreement to the contrary, neither the JSC nor

Equillium’s Chair shall have any power to: (A) determine any issue in a manner that would conflict with the express terms and conditions of this Agreement; or (B) modify or amend the terms and conditions of this Agreement.

3.7 Financial Representative. Each party shall appoint one (1) representative with expertise in the areas of accounting, cost allocation, budgeting and financial reporting (each, a “Financial Representative”) no later than [ …***…] after the Effective Date. Such Financial Representatives shall consult with the JSC, in order to address the financial, budgetary and accounting issues that arise in connection with the Biocon Preclinical Activities. Each Financial Representative may be replaced at any time by the represented party by providing notice thereof to the other party. The Financial Representatives will meet as they or the parties, through the JSC, may agree is appropriate.

4. DEVELOPMENT AND COMMERCIALIZATION

4.1 Equillium Responsibility. Except as expressly set forth in Sections 4.2 and 4.3 or in the Clinical Supply Agreement or any Commercial Supply Agreement, Equillium shall be solely responsible for the development, manufacturing, registration and commercialization of Products in the Field in the Equillium Territory, at Equillium’s sole expense. Without limiting the generality of the foregoing, Equillium shall:

(a) conduct Indication-specific preclinical studies of ITO in JSC-approved Indications to support the submission of Regulatory Filings, at Equillium’s sole expense;

(b) prepare and submit all required Regulatory Filings in connection with obtaining and maintaining Regulatory Approvals and Orphan Designation with respect to Products in the Equillium Territory, at Equillium’s sole expense. All of such Regulatory Filings relating to Products in the Equillium Territory shall be submitted in the name of, and owned by, Equillium (or its Affiliate or Sublicensee, as applicable);

(c) be responsible for obtaining funding (which may include, without limitation, government funding) for the development of ITO and Products for the Equillium Territory (whether Equillium conducts such development activities in the Equillium Territory or the Biocon Territory); and

(d) review the need for, and, if required, seek and use Commercially Reasonable Efforts to obtain OFAC license(s) necessary for clinical development and/or commercialization of ITO and Product in the US.

4.2 Biocon Responsibility. Notwithstanding the provisions of Section 4.1 to the contrary, and without limiting the generality of Section 4.5:

(a) Biocon Preclinical Activities.

(i) Available Materials. Promptly after the Effective Date, Biocon shall provide to Equillium true and complete copies of Biocon’s updated Investigator’s Brochure for all available CHO-derived ITO formulations and related supporting materials, and all preclinical, toxicology and CMC Data existing as of the Effective Date for all available CHO-derived ITO formulations; in each case, at Biocon’s sole expense, subject to Section 4.2(a)(iii).

(ii) Preclinical Studies and CMC Activities. Biocon shall:

(1) guided by the JSC-approved initial Indication for which Product will be developed in the Equillium Territory, perform, in accordance with JSC-approved protocols and GLP, all IND-enabling preclinical studies of CHO-derived ITO and Product necessary for the filing of INDs for Product in the Equillium Territory (collectively, “IND-Enabling Studies”); provided, however, that the IND-Enabling Studies shall exclude Indication-specific preclinical animal models, which shall be the sole responsibility of Equillium;

(2) perform all IND-Enabling CMC Activities; and

(3) deliver to Equillium all Data and other Information generated in performance of the IND-Enabling Studies and IND-Enabling CMC Activities in a form and format suitable for inclusion in INDs for Product in the Equillium Territory;

in each case, at […***…] expense, subject to Section 4.2(a)(iii). Biocon shall maintain complete and accurate records of the performance of all IND-Enabling Studies and IND-Enabling CMC Activities, including all Data, Inventions and other Information generated or made in the course of such performance, which records shall be maintained in accordance with Biocon’s standard practices and shall in any event be maintained in a manner sufficient for Equillium’s filing of INDs for Product in the Equillium Territory. Upon reasonable prior written notice, Biocon shall permit Equillium to inspect such records, and, upon Equillium’s request,

shall provide copies of such records. Biocon shall deliver to Equillium the draft and final reports for each IND-Enabling Study and all IND-Enabling CMC Activities promptly following the availability thereof.

(iii) Biocon Preclinical Expenses. Biocon shall maintain records of Biocon Preclinical Expenses, including the number of Biocon FTEs devoted by Biocon to Biocon Preclinical Activities, which shall be made available to Equillium for inspection through the Financial Representatives from time to time upon the request of Equillium’s Financial Representative.

(b) Supply of ITO and Product. Notwithstanding the provisions of Section 4.1 to the contrary, Biocon shall be responsible for manufacturing, or having manufactured, and supplying to Equillium:

(i) ITO (both NS0-derived and CHO-derived) and ITO surrogate monoclonal antibodies suitable for use in general research and IND-enabling, GLP-compliant preclinical studies in quantities sufficient for the conduct of the preclinical studies contemplated by the Development Plan, at Biocon’s sole expense;

(ii) sufficient quantities of ITO finished drug product (all current and future CHO-derived IV and SC formulations), manufactured in accordance with GMP, for use in the conduct of clinical trials of Product in three (3) Orphan Indications in the Equillium Territory, at Biocon’s sole expense until FDA approval of the first NDA for Product in any Indication (“First US Approval”). For clarity, if Equillium discontinues clinical development of Product in a particular Orphan Indication and instead pursues clinical development of Product in a different Orphan Indication prior to First US Approval, Biocon shall remain obligated to supply ITO finished drug product pursuant to this Section 4.2(b)(ii) for such replacement Orphan Indication, provided that at no time will Biocon be obligated to supply ITO finished drug product pursuant to this Section 4.2(b)(ii) for use in clinical trials of more than three (3) Orphan Indications at any given time;

(iii) after First US Approval, sufficient quantities of ITO finished drug product (all current and future CHO-derived IV and SC formulations), manufactured in accordance with GMP, for use in the conduct of clinical trials of Product for Orphan Indications in the Equillium Territory, at a price equal to Biocon’s Cost of Goods of such ITO finished drug product; and

(iv) sufficient quantities of ITO finished drug product (all current and future CHO-derived IV and SC formulations), manufactured in accordance with GMP, for use in the conduct of clinical trials of Product for Indications other than Orphan Indications in the Equillium Territory, at a price equal to Biocon’s Cost of Goods of such ITO finished drug product.

All ITO finished drug product to be supplied for the purposes set forth in the preceding clauses (ii), (iii) and (iv) of this Section 4.2(b) (collectively, “Clinical Material”) will be manufactured and supplied by Biocon pursuant to, and in accordance with the terms and conditions of, the Clinical Supply Agreement. Biocon shall keep complete and accurate records related to the manufacture of the Clinical Material and the methods and facilities used by it for such manufacture as necessary to comply with GMP and Applicable Laws and to permit the Clinical Material to be used in humans. Upon reasonable notice by Equillium, Biocon shall make such records available to Equillium or its designated representatives for inspection, examination and copying, and, if requested by Equillium, Biocon shall deliver to Equillium, as promptly as practicable, copies of such records. All such documentation shall be provided in English, and in the case of translations, the original un-translated document shall also be provided. All original records shall be retained and archived by Biocon in accordance with GMP and Applicable Laws for the minimum retention period under Applicable Laws. Upon Equillium’s written request, Biocon shall provide to Equillium such information, documentation and data, including, without limitation, CMC Data, in Biocon’s possession relating to the Clinical Material or Product or the manufacture of Clinical Material or Product (or true and complete copies thereof) as Equillium may require for IND, NDA and other submissions to Regulatory Authorities in the Equillium Territory. Biocon represents and warrants to Equillium that all Clinical Material will: (i) upon delivery to Equillium, conform to the applicable specifications for Clinical Material in effect at the time of delivery; (ii) have been manufactured in compliance with GMP, as applicable to investigational drugs; and (iii) upon delivery to Equillium, be free and clear of all liens and encumbrances.

(c) Stage 2 Study. Biocon shall, at its sole expense, conduct the Stage 2 Study, in accordance with Biocon’s protocol until the Stage 2 Study is completed or terminated, at its sole expense.

(d) Diligence. Biocon shall use Commercially Reasonable Efforts to perform its obligations under this Section 4.2 in an expeditious manner.

4.3 Commercial Supply for the Equillium Territory. Subject to the terms and conditions of this Agreement, during the Term, Biocon agrees to Manufacture and supply to Equillium such quantities of Product for commercial use and distribution in the Equillium

Territory as may be set forth on purchase orders placed by Equillium in accordance with the provisions of the Commercial Supply Agreement, and Equillium agrees that Biocon shall be Equillium’s exclusive supplier for the Product for the Equillium Territory on the terms set forth in the Commercial Supply Agreement. No later than six (6) months prior to the anticipated initiation of the first Pivotal Trial conducted by or on behalf of Equillium, the parties shall negotiate in good faith and enter into a separate written manufacturing and supply agreement containing commercially reasonable terms (the “Commercial Supply Agreement”) pursuant to which the purchase price for the commercial supply of Product shall be equal to […***…]% of Biocon’s Fully-Burdened Manufacturing Cost, as well as a commercially reasonable and customary quality assurance agreement (the “Commercial Quality Agreement”), pursuant to which Biocon shall manufacture and supply to Equillium, or have manufactured and supplied to Equillium, and Equillium shall accept such manufacture and supply from Biocon as Equillium’s exclusive supplier, Product for commercialization in the Field in the Equillium Territory. Without limiting the generality of the foregoing, the Commercial Supply Agreement shall provide as follows:

(a) Forecasts and Ordering. On a basis to be agreed between the parties following good faith discussions, the Commercial Supply Agreement shall contain a mechanism by which Equillium provides Biocon with rolling forecasts of its estimated requirements of Product to be supplied to it during the term of the Commercial Supply Agreement. Such forecasting mechanism will stipulate that the Products estimated to be supplied during a particular time frame in the rolling period (not to exceed the first […***…] calendar quarter periods of each forecast) will constitute a firm binding purchase order by Equillium for those Products. The parties shall also agree on an upper maximum limit (measured as a percentage beyond […***…]% of the quantity of Products set out in a binding forecast (“Additional Quantities”)) of Products to be supplied pursuant to a binding forecast, subject to Biocon’s facility having the capacity to manufacture more than […***…]% of the quantity of Products set out in a binding forecast at the relevant time.

(b) Shortfalls and Allocation of Supply. If Biocon is, or anticipates that it will be, unable to supply to Equillium, in whole or in part, Equillium’s forecasted requirements of Product on a timely basis due to a shortage of production capacity, shortage of raw materials, or any other reason, Biocon shall promptly notify Equillium in writing of such shortage of production capacity or production problem or other reason, within […***…], and if possible, the date such shortage or production problem is expected to end. The parties will discuss the matter and shall use good faith efforts to achieve an equitable solution with the least impact on both parties’ ability to commercialize and market Product in their respective territories. Biocon shall use Commercially Reasonable Efforts to remedy any shortfall of Product as soon as practicable, and Biocon shall allocate its available production capacity for the production of Product in a manner proportional to the number of units of Product sold in the previous […***…] in the Biocon Territory and Equillium Territory, respectively, or, should such sales have not been commenced, in proportion to the number of units of Product in then-scheduled production runs for the Biocon Territory and the Equillium Territory, respectively.

(c) Second Site/Source. Biocon shall have the right to use the services of its Affiliates and Third Party contractors, including CMOs, to assist such Biocon in fulfilling its obligations and exercising its rights under the Commercial Supply Agreement; provided that (i) the JSC approves any contractor in advance, such approval not to be unreasonably withheld or delayed by the Equillium representatives on the JSC; (ii) none of Equillium’s rights under the Commercial Supply Agreement or this Agreement are diminished or otherwise adversely affected as a result of Biocon’s use of Affiliates or contractors; and (iii) the contractor or Affiliate has entered into a written agreement with Biocon binding such Person to the obligations Biocon has to Equillium, including obligations of intellectual property assignment and confidentiality and non-use, and containing any other provisions normal and customary for similar types of agreements consistent with the Commercial Supply Agreement and this Agreement; and provided, further, that Biocon shall at all times be responsible for the satisfactory accomplishment of its obligations under and in accordance with, and the contractor’s or Affiliate’s compliance with, the terms and conditions of the Commercial Supply Agreement and this Agreement. For clarity, for purposes of clause (i) of the preceding sentence, it shall not be unreasonable for the Equillium representatives on the JSC to withhold approval of a proposed contractor if such contractor (A) has received any Form FD-483 notice (or foreign equivalent) or any FDA or other Regulatory Authority refusal to file, rejection or warning letter that has not been fully addressed by such contractor to the satisfaction of the applicable Regulatory Authority, (B) is debarred under Applicable Laws in the US, including 21 U.S.C. §335a, or any comparable Applicable Laws outside of the US. Without prejudice to the generality of the foregoing, in the event of a Failure to Supply on Biocon’s part, the parties will evaluate alternative approaches to source the shortfall in supply, which may include, without limitation, Biocon’s performance of a manufacturing technology transfer (the reasonable costs of such technology transfer to be borne by Biocon) to a CMO identified by the JSC and appointed by the JSC with Biocon’s prior written consent, such consent not to be unreasonably withheld, to permit such CMO to manufacture ITO and Product, using the manufacturing process developed and used by Biocon, for use and distribution in the Field in the Equillium Territory.

(d) Failure to Supply. A Failure to Supply as used in this Section 4.3 means that Biocon does not supply according to the terms of the Commercial Supply Agreement at least […***…] percent ([…***…]%) of the quantity of all Products (excluding, for the avoidance of doubt, Additional Quantities) ordered by Equillium pursuant to valid and binding purchase orders placed in accordance with the ordering procedure agreed in the Commercial Supply Agreement during any two consecutive calendar quarters, except to the extent such failure has been caused by a force majeure event which is beyond Biocon’s reasonable control, and subject to the limitations on the maximum amount Equillium is entitled to order which will be described in the Commercial Supply Agreement.

(e) Right of Biocon to Resume Manufacturing. On a basis to be agreed between the parties following good faith discussions, the Commercial Supply Agreement shall contain a mechanism by which, following a Failure to Supply and the enabling of a CMO to provide a secondary source of supply of Product pursuant to Section 4.3(c), Biocon may resume its supply obligations if it provides Equillium with a commercially reasonable proposal and evidence that it is ready, willing and able, directly or through subcontractors, to resume its supply obligations under the Commercial Supply Agreement, in which case the Parties will work together in good faith to develop and mutually agree upon a transition plan that achieves the following objectives: (i) minimizes disruption to the continued manufacture and supply of Product; (ii) enables Biocon to resume operation of its facility(ies) as the primary source of Product as soon as reasonably practicable; and (iii) maintains on an ongoing basis the Third Party facility established following a Failure to Supply and the enabling of a CMO to provide a secondary source of supply of Product pursuant to Section 4.3(c).

4.4 Performance Standards. Each party shall conduct, or have conducted, all ITO and Product development, manufacture, registration and commercialization activities performed by it or on its behalf in good scientific manner and in compliance with all Applicable Laws and, as applicable, GLP, GCP and/or GMP.

4.5 Technology Transfer; Exchange of Information.

(a) Commencing promptly after the Effective Date, Biocon shall disclose to Equillium all existing and available (in recorded form) Biocon Know-How as reasonably required for the development, registration or commercialization of ITO and Product in the Field in the Equillium Territory. Thereafter, on an ongoing basis, Biocon shall also disclose to Equillium all additional Biocon Know-How generated after the Effective Date as reasonably required for the development, registration or commercialization of ITO and Product in the Field in the Equillium Territory. Without limiting the generality of the foregoing, Biocon shall provide to Equillium true and complete copies of all written, graphic or electronic embodiments of Data within the Biocon Know-How. The Biocon Know-How shall be transferred to Equillium in a format to be agreed upon by the parties, such agreement not to be unreasonably withheld. With respect to any of the foregoing that is in a language other than English, Biocon shall also provide Equillium with English translations thereof.

(b) On an ongoing basis during the Term, Equillium shall disclose to Biocon all Equillium Know-How as reasonably required for the development, registration, manufacturing or commercialization of ITO and Product in the Field in the Biocon Territory. Without limiting the generality of the foregoing, Equillium shall provide to Biocon true and complete copies of all written, graphic or electronic embodiments of Data within the Equillium Know-How. The Equillium Know-How shall be transferred to Biocon in a format to be agreed upon by the parties, such agreement not to be unreasonably withheld.

4.6 Rights of Access and Reference to Regulatory Documents.

(a) Equillium hereby grants to Biocon the right to access and reference all Regulatory Filings submitted to, and Regulatory Approvals obtained from, any Regulatory Authority in the Equillium Territory by Equillium for Products and to use the Data therein; in each case, solely for the purposes of Biocon and […***…] (and their respective affiliates and sublicensees) (i) obtaining and maintaining Regulatory Approvals for, and conducting business development with respect to, ITO and Products outside the Equillium Territory, and (ii) complying with applicable pharmacovigilance and other regulatory requirements with respect to ITO and Products outside the Equillium Territory. Equillium shall, promptly upon Biocon’s request, file with the applicable Regulatory Authority(ies) such letters of access or reference as may be necessary to accomplish the intent of this Section 4.6(a).

(b) Biocon hereby grants to Equillium the right to access and reference all Regulatory Filings submitted to, and Regulatory Approvals obtained from, any Regulatory Authority in the Biocon Territory by Biocon for Products and to use the data, including but not limited to any non-clinical and clinical data, therein; in each case, solely for the purposes of (i) obtaining and maintaining Regulatory Approvals for Products in the Field in the Equillium Territory, and (ii) complying with applicable pharmacovigilance and other regulatory requirements with respect to such Products in the Equillium Territory. Biocon shall, promptly upon Equillium’s request, file with the applicable Regulatory Authority(ies) such letters of access or reference as may be necessary to accomplish the intent of this Section 4.6(b).

4.7 Safety Data Exchange. Each party shall be solely responsible, at its own expense, for complying with all applicable regulatory requirements with respect to Products in such party’s Territory, including all safety reporting to Regulatory Authorities in such party’s Territory. The parties shall, promptly upon reasonable request by either party, negotiate in good faith and enter into a pharmacovigilance/safety data exchange agreement for Products (the “PV Agreement”), which shall set forth standard operating procedures governing the collection, investigation, reporting, and exchange of information concerning adverse drug reactions/experiences. The terms of the PV Agreement shall be sufficient to permit each party to comply with its regulatory and legal requirements for the management and reporting of safety data regarding such Products by providing for the exchange of relevant information in appropriate format within applicable timeframes.

4.8 Diligence.

(a) General Diligence Obligation. Equillium (directly or through its Affiliates or Sublicensees) shall use Commercially Reasonable Efforts to develop and seek Regulatory Approval for, and, if Regulatory Approval is obtained, to commercialize Product in the Field in the Equillium Territory. In addition, Equillium shall use Commercially Reasonable Efforts to secure funding for the development of Product in two or more Indications.

(b) Specific Diligence Requirements. Notwithstanding the generality of Section 4.8(a), the following shall be considered, without limitation, to represent a failure of Equillium to comply with Section 4.8(a):

(i) If, following Stage 2 Study Completion, Equillium fails either (A) within two (2) years to dose the first patient in a PoC Study, and/or (B) to use Commercially Reasonable Efforts to pursue clinical development of Product in at least one Indication for any continuous period greater than three (3) years (subject to extension as described below), Biocon shall have the right to terminate this Agreement in accordance with Section 10.2(b), subject to Section 10.2(c). The two-year and three-year periods in (A) and (B) above shall be extended to the extent of any delays directly attributable to events beyond the reasonable control of Equillium. By way of example and not of limitation, for purposes of this Section 4.8(b)(i), “events beyond the reasonable control of Equillium” include Biocon’s failure to supply Product in accordance with the Clinical Supply Agreement (except to the extent directly attributable to Equillium’s failure to comply with its obligations under the Clinical Supply Agreement), imposition of a clinical hold, Biocon’s failure or delay in performing its obligations under Article 4 that are a prerequisite for Equillium’s clinical development of Product, or delays in receiving required OFAC license(s). However, the foregoing two-year period in (A) and three-year period in (B) above shall not be extended by more than one (1) year in each case by reason of any and all events beyond the reasonable control of Equillium, unless, and only to the extent that, any such delay beyond three (3) years (in the case of (A)) and four (4) years (in the case of (B)) is directly attributable to Biocon’s failure to supply Product in accordance with the Clinical Supply Agreement (except to the extent directly attributable to Equillium’s failure to comply with its obligations thereunder) or Biocon’s failure or delay in performing its obligations under Article 4 that are a prerequisite for Equillium’s clinical development of Product. This Section 4.8(b)(i) and Biocon’s rights hereunder shall automatically terminate and be of no further force or effect upon First US Approval.

(ii) If Equillium has not completed one PoC Study of Product in an Indication that is not an Orphan Indication by the seventh (7th) anniversary of Stage 2 Study Completion (subject to extension as described below), then the Field (if previously expanded pursuant to Section 2.3) shall automatically be restricted to mean the treatment, prevention and/or diagnosis of Orphan Indications for the remainder of the Term. The foregoing seven-year period shall be extended to the extent of any delays directly attributable to events beyond the reasonable control of Equillium (as described in Section 4.8(b)(i)); provided, however, that the foregoing seven-year period shall not be extended by more than one (1) year by reason of any and all events beyond the reasonable control of Equillium, unless, and only to the extent that, any such delay beyond eight (8) years is directly attributable to Biocon’s failure to supply Product in accordance with the Clinical Supply Agreement (except to the extent directly attributable to Equillium’s failure to comply with its obligations thereunder) or Biocon’s failure or delay in performing its obligations under Article 4 that are a prerequisite for Equillium’s clinical development of Product.

The auditor will send a copy of the report to the Audited Party at the same time it is sent to the other party. The report sent to both parties will include the methodology and calculations used to determine the results. Prompt adjustments shall be made by the parties to reflect the results of such audit. The party exercising its audit right under this Section shall bear the full cost of such audit unless such audit discloses an underpayment by the Audited Party of more than […***…]% of the amount due for any calendar year under this Agreement, in which case, the Audited Party shall bear the cost of such audit which cost shall not exceed […***…] percent ([…***…]%) of the underpayment and shall promptly remit to the other party the amount of any underpayment.

6.5 Late Payments. In the event that any payment due under this Agreement is not made when due, the payment shall accrue interest at a rate per annum that is […***…] basis points (i.e., […***…] percentage points) above the then-current prime rate quoted by Citibank in New York City for the period from the due date for payment until the date of actual payment; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit the party entitled to payment from exercising any other rights it may have as a consequence of the lateness of any payment.

7. INTELLECTUAL PROPERTY

The parties shall mutually agree on a case-by-case basis (A) whether to bring (or defend) and control any action or proceeding with respect to Infringement of any Joint Patent anywhere in the world to the extent the Infringement is not Competitive Infringement, (B) which party would bring (or defend) and control such action, and (C) how the expenses of, and any recovery from, any such action would be allocated.

(d) Cooperation. In the event a party brings (or defends) an infringement action in accordance with this Section 7.5, or in the event a party is entitled to bring (or defend) an infringement action in accordance with this Section 7.5 but lacks standing to do so, the other party shall cooperate fully, including, if required to bring (or defend) such action, the furnishing of a power of attorney or being named as a party, provided that the party bringing (or defending) or entitled to bring (or defend) such action shall pay or reimburse the reasonable out-of-pocket costs incurred by the other party in providing such cooperation. Neither party shall enter into any settlement or compromise of any action under this Section 7.5 which would in any manner alter, diminish, or be in derogation of the other party’s rights under this Agreement without the prior written consent of such other party, which shall not be unreasonably withheld.

(e) Recovery. Except as otherwise agreed by the parties in connection with a cost-sharing arrangement, any recovery realized by a party as a result of any action or proceeding pursuant to this Section 7.5, whether by way of settlement or otherwise, shall be applied first to reimburse the parties’ documented out-of-pocket legal expenses incurred in connection with such action or

proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses), and any remaining amounts shall be […***…]; provided, however, that:

(i) any recovery realized by Equillium as a result of any action brought (or defended) and controlled by Equillium pursuant to Section 7.5(a)(i) or Section 7.5(c)(i)(1) (after reimbursement of the parties’ documented out-of-pocket legal expenses relating to the action or proceeding) shall be allocated as follows:

(1) compensatory damages shall be treated as […***…]; and

(2) non-compensatory damages shall be […***…]; and

(ii) any recovery realized by Biocon as a result of any action brought and controlled by Biocon pursuant to Section 7.3(b)(ii) or Section 7.5(c)(i)(2) (after reimbursement of the parties’ documented out-of-pocket legal expenses relating to the action or proceeding) shall be allocated as follows:

(1) compensatory damages attributable to lost sales or lost profits, or a reasonable royalty, with respect to Supported Products shall be treated as […***…];

(2) all compensatory damages other than those described in Section 7.5(e)(ii)(1) shall […***…]; and

7.6 Infringement of Third Party Rights. Each party shall promptly notify the other in writing of any allegation by a Third Party that the activity of either party pursuant to this Agreement infringes or may infringe the intellectual property rights of such Third Party, provided that in the event such Third Party also alleges the invalidity, unenforceability or non-infringement of any of the Biocon Patents or Joint Patents, such allegation or claim shall be handled as a Competitive Infringement. Neither party shall have the right to settle any patent infringement litigation under this Section 7.6 in a manner that diminishes the rights or interests of the other party without the written consent of such other party (which shall not be unreasonably withheld).

8. CONFIDENTIALITY

8.1 Confidential Information. Except to the extent expressly authorized by this Agreement, each party agrees that, during the Term, and for five years thereafter, such party (the “Receiving Party”) shall keep confidential, and shall not publish or otherwise disclose and shall not use for any purpose other than as expressly provided for in this Agreement, any Information furnished to it by the other party (the “Disclosing Party”) pursuant to this Agreement or any Confidentiality Agreement (collectively, “Confidential Information”). The Receiving Party may use Confidential Information only to the extent required to accomplish the purposes of this Agreement. The Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but in no event less than reasonable care) to ensure that its, and its Affiliates’, employees, agents, consultants and other representatives (“Representatives”) do not disclose or make any unauthorized use of the Confidential Information. The Receiving Party shall promptly notify the Disclosing Party upon discovery of any unauthorized use or unauthorized disclosure of the Disclosing Party’s Confidential Information.

8.2 Exceptions. Confidential Information shall not include any information which the Receiving Party can prove by competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party in violation of this Article 8, generally known or available; (b) is known by the Receiving Party or any of its Affiliates at the time of receiving such information, as evidenced by its records; (c) is hereafter furnished to the Receiving Party or any of its Affiliates by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the Receiving Party or any of its Affiliates, independently of the activities undertaken by the Receiving Party pursuant to this Agreement and without the use or knowledge of Confidential Information of the Disclosing Party.

8.3 Authorized Disclosure. Notwithstanding the provisions of Section 8.1, the Receiving Party may disclose Confidential Information of the Disclosing Party as expressly permitted by this Agreement, or if and to the extent such disclosure is reasonably necessary in the following instances:

(a) filing or prosecuting Patent Rights as permitted by this Agreement;

(b) enforcing such party’s rights under this Agreement and in performing its obligations under this Agreement;

(c) prosecuting or defending litigation as permitted by this Agreement, subject to the final paragraph of this Section 8.3;

(d) complying with applicable court orders, applicable laws, rules or regulations, subject to the final paragraph of this Section 8.3;

(e) as determined in the Receiving Party’s reasonable discretion, the listing rules of any exchange on which the Receiving Party’s securities are traded;

(f) disclosure in Regulatory Filings that the Receiving Party has the right to make under this Agreement;

(g) disclosure to the Receiving Party’s Affiliates, to actual or potential Sublicensees, and to the Receiving Party’s and its Affiliates’ Representatives who, in each case, have a need to know such information in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement, provided, in each case, that any such Affiliate, actual or potential Sublicensee, or Representative agrees to be bound by terms of confidentiality and non-use at least as restrictive as those set forth in this Article 8; and

(h) disclosure to Third Parties in connection with due diligence or similar investigations by such Third Parties, and disclosures to potential Third Party investors in confidential financing documents, provided, in each case, that any such Third Party agrees to be bound by reasonable obligations of confidentiality and non-use.

Notwithstanding the foregoing, in the event the Receiving Party is required to make a disclosure of the Disclosing Party’s Confidential Information pursuant to Section 8.3(c) or 8.3(d), it will, except where impracticable, (i) give reasonable advance notice to the Disclosing Party of such disclosure, (ii) use efforts to secure confidential treatment of such information at least as diligent as the Receiving Party would use to protect its own confidential information, but in no event less than reasonable efforts, and (iii) cooperate with any efforts by the Disclosing Party, at the Disclosing Party’s request and expense, to secure confidential treatment of such Confidential Information. Disclosure by the Receiving Party of Confidential Information in accordance with any of the foregoing provisions of this Section 8.3 shall not, in and of itself, cause the information so disclosed to cease to be treated as Confidential Information under this Agreement, except to the extent that, by virtue of disclosure by the Receiving Party in full compliance with this Section 8.3, such information becomes generally known or available.

8.4 Publications. Each party and its Affiliates shall be free to publish, and to authorize Sublicensees to publish, the results of any preclinical study or clinical trial of a Product conducted by or on behalf of such party or its Affiliate or Sublicensee, provided that the other party has a reasonable opportunity not less than […***…] prior to the date of publication to review the proposed publication and provide comments. If such comments involve a redaction of Confidential Information of such reviewing party, the publishing party shall incorporate such comments. If such comments involve the identification of patentable material in such proposed publication, the publishing party shall delay publication for up to […***…] until the appropriate party seeks patent protection for such information. Any such publication shall acknowledge, as appropriate, the contribution of the other party, its employees, agents and representatives, or if appropriate.

8.5 Public Announcements.

(a) Press Releases. It is understood that each party may desire or be required to issue press releases relating to this Agreement or activities hereunder. Neither party may issue any press release without the prior review and approval of the other party during the first […***…] after the Effective Date. Notwithstanding the foregoing, each party shall be free to issue such subsequent press releases without the prior review or approval of the other party, that such party determines are reasonably necessary to comply with Applicable Laws, including disclosure requirements of the U.S. Securities and Exchange Commission or foreign counterpart, or with the requirements of any stock exchange on which securities issued by such party is traded. In addition, each party may make public statements regarding this Agreement in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst calls, so long as the contents of any such public statement or press release do not reveal non-public information about the other party.

(b) Filing of this Agreement. The parties shall coordinate in advance with each other in connection with the filing of this Agreement (including redaction of certain provisions of this Agreement) with any securities authority or with any stock exchange on which securities issued by a party or its Affiliate are traded, and each party will use reasonable efforts to seek and obtain confidential treatment for the terms proposed to be redacted; provided that each party will ultimately retain control over what terms are disclosed to any securities authority or stock exchange, as the case may be, to the extent such party determines, on the advice of legal counsel, that disclosure is reasonably necessary to comply with Applicable Laws, including disclosure requirements of the U.S. Securities and Exchange Commission or foreign counterpart, or with the requirements of any stock exchange on which securities issued by a party or its Affiliates are traded, and provided further that the parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies.

10.2 Termination for Material Breach.

(a) Material Breach Other Than Breach of Equillium Diligence Obligations. Subject to Section 10.2(c), and except in the case of a material breach covered by Section 10.2(b), each party shall have the right, in the event of material breach of this Agreement by the other party, to terminate this Agreement upon written notice to the other party if such other party is in material breach of this Agreement and has not cured such breach within 90 days after notice from the terminating party requesting cure of the breach. Any such termination shall become effective at the end of such 90-day period unless the breaching party has cured such breach prior to the end of such period. Notwithstanding the foregoing or Section 10.4 to the contrary, but without limiting Biocon’s rights under Section 10.2(b), after initiation of the first Pivotal Trial of Product, Biocon may not terminate this Agreement pursuant to this Section 10.2(a), except in the case of uncured material breach by Equillium of its payment obligations hereunder or uncured material breach of Section 2.1, Section 2.4, Section 2.6, Section 4.3, Section 7.5, Section 8.1 or Section 9.6 but for clarity, Biocon may pursue any and all remedies that may be available to it at law or in equity as a result of such breach by Equillium.

(b) Material Breach of Equillium Diligence Obligation. If Biocon in good faith believes that Equillium has failed to comply with its obligations under Section 4.8 (“Diligence Obligations”), Biocon shall notify Equillium, and Equillium shall have 60 days from the date of such notice (the “Diligence Notice Period”) in which to provide information to Biocon reasonably demonstrating Equillium’s compliance with its Diligence Obligations. If Equillium provides such information to Biocon prior to expiration of the Diligence Notice Period, but Biocon continues to believe in good faith that Equillium is not complying with its Diligence Obligations, then Biocon may so notify Equillium in writing, in which event Equillium and Biocon shall promptly meet to discuss the matter in good faith and attempt to agree upon a mutually agreeable plan for Equillium to regain compliance with its Diligence Obligations. Following such meeting, if either (i) the parties do not agree upon a plan to address such failure by Equillium within 30 days after expiration of the Diligence Notice Period, or (ii) Equillium fails to comply with its obligations under any mutually agreed upon plan to address such failure by Equillium, then, subject to Section 10.2(c) below, Biocon shall have the right, at its sole discretion, to terminate this Agreement.

(c) Dispute Regarding Breach. Any right to terminate this Agreement under this Section 10.2 shall be stayed and the cure period tolled in the event that, during any cure period, the party alleged to have been in material breach shall have initiated dispute resolution in accordance with Article 12 with respect to the alleged breach, which stay and tolling shall continue until such dispute has been resolved in accordance with Article 12.

10.3 At-Will Termination by Equillium. Equillium shall have the right to terminate this Agreement on a country-by-country basis for any reason or for no reason at any time upon 120 days’ prior written notice to Biocon.

(b) Effect of Termination on Fully-Paid Licenses. If the Royalty Term with respect to a Product or Supported Product (as applicable) in any country has expired on or before any termination of this Agreement prior to the expiration hereof, the license granted to the applicable party hereunder with respect to such Product or Supported Product in such country (i.e., the Equillium License or the Biocon License, as applicable) shall survive such termination of this Agreement.

(c) Termination by Equillium Pursuant to Section 10.2. Solely in the event of termination of this Agreement by Equillium pursuant to Section 10.2, the Equillium License and the Biocon License shall automatically terminate and revert to the granting party; in each case, except as expressly provided in Section 10.4(b).

(d) Termination by Biocon Pursuant to Section 10.2 or by Equillium Pursuant to Section 10.3. Solely in the event of termination of this Agreement by Biocon pursuant to Section 10.2, or by Equillium pursuant to Section 10.3, and without prejudice to Biocon’s other rights and remedies, the following provisions (in addition to the provisions of Section 10.4(b)) shall apply:

(i) the Equillium License shall automatically terminate and revert to Biocon, except as expressly provided in Section 10.4(b);

(ii) effective as of such termination, Equillium shall, and it hereby does, covenant, during the period beginning on the effective date of such termination and expiring, on a country-by-country basis, upon the later to occur of: (A) expiration of the last-to-expire Valid Claim of the Biocon Patents, Equillium Patents and Joint Patents covering the manufacture, use or sale of Product in each country of the Equillium Territory; and (B) expiration of all Regulatory Exclusivity for all Products in such country: (A) not to develop, make, have made, sell, have sold, offer for sale, import or otherwise exploit ITO or Product in the Unlimited Field in such country; and (B) not to cause or permit, or grant any license or other right to, any of its Affiliates or any Third Party to engage in any of the activities prohibited by the preceding clause (A) of this Section 10.4(d)(ii); except, in each case, as expressly provided in Section 10.4(b).

(iii) effective as of such termination, Equillium shall, and it hereby does, grant to Biocon a non-exclusive, royalty-free license, with the right to sublicense through multiple tiers of sublicense, under Equillium Technology and Equillium’s interest in the Joint Patents, solely to develop, make, have made, use, sell, offer for sale, have sold and import ITO and Products in the Unlimited Field in the Equillium Territory;

(iv) effective as of such termination, Equillium shall, and it hereby does, grant to Biocon, a right of first negotiation, exercisable within 60 days after the termination date, upon commercially reasonable terms and conditions to be negotiated in good faith by the parties for up to 90 days from the date of exercise:

(1) to obtain an exclusive, royalty-bearing license, with the right to sublicense through multiple tiers of sublicense, under Equillium Technology and Equillium’s interest in the Joint Patents, solely to develop, make, have made, use, sell, offer for sale, have sold and import ITO and Products in the Unlimited Field in the Equillium Territory; and

(2) to have transferred or assigned to Biocon or its designee all Regulatory Filings for Products in the Unlimited Field in the Equillium Territory held in the name of Equillium or any of its Affiliates.

(v) Biocon shall have the right, but not the obligation, to purchase from Equillium any or all usable inventory of ITO and Product in Equillium’s or its Affiliates’ possession as of the date of expiration. Such inventory shall be provided at a transfer price equal to Equillium’s cost of such inventory (as reflected on Equillium’s books and records used to prepare its financial statements), plus freight, insurance, transportation, postage and handling.

(vi) the Biocon License shall survive; provided that, if Biocon grants a Third Party an exclusive license to develop and commercialize Product in the Equillium Territory and the terms of such Third Party license require Biocon to pay royalties to such Third Party licensee on Biocon’s net sales of Product in a country of the Biocon Territory, then 100% of the royalties actually paid by Biocon to such Third Party licensee on sales of Product in such country for a calendar quarter will be creditable against the royalty payments payable by Biocon to Equillium pursuant to Section 5.4(b) in such country for such calendar quarter; provided, however, that in no event will the royalties owed by Biocon to Equillium hereunder pursuant to Section 5.4(b) in such country for any calendar quarter be reduced to less than 0% (i.e., in no event shall Equillium owe any royalties to Biocon with respect to Net Sales of Product in the Biocon Territory); and provided, further, that Biocon will not be entitled to credit any portion of royalties paid by Biocon to such Third Party licensee with respect to any Other Active in any Combination Product.

10.5 Accrued Obligations; Survival. Upon any termination or any expiration of this Agreement, all rights and obligations of the parties under this Agreement shall terminate, except as expressly provided in this Section 10.5 or elsewhere in this Article 10. Neither expiration nor any termination of this Agreement shall relieve either party of any obligation or liability accruing prior to such expiration or termination, nor shall expiration or any termination of this Agreement preclude either party from pursuing all rights and remedies it may have under this Agreement, at law or in equity, with respect to breach of this Agreement. In addition, the parties’ rights and obligations under Sections 2.7, 7.1, 8.1, 8.2, 8.3, 9.8, 9.9, 10.4, 10.5, 10.6 and 10.7 and Articles 6, 11, 12 and 13 of this Agreement shall survive expiration or any termination of this Agreement.

10.7 Damages; Relief. Termination of this Agreement shall not preclude either party from claiming any other damages, compensation or relief that it may be entitled to hereunder as a result of the other party’s breach of this Agreement.

Biocon hereby agrees to save, defend, indemnify and hold harmless Equillium, its Affiliates and their respective officers, directors, employees, consultants and agents (the “Equillium Indemnitees”) from and against any and all Losses to which any Equillium Indemnitee may become subject as a result of any Claim to the extent such Losses arise out of or relate to: (a) the exercise of the Biocon License by or on behalf of Biocon or any of its Affiliates or Sublicensees; (b) the gross negligence or willful misconduct of any Biocon Indemnitee; or (c) the breach by Biocon of any warranty, representation, covenant or agreement made by Biocon in this Agreement; in each case except to the extent such Losses result from the gross negligence or willful misconduct of any Equillium Indemnitee or the breach by Equillium of any warranty, representation, covenant or agreement made by Equillium in this Agreement.

11.3 Control of Defense. In the event a party (the “Indemnified Party”) seeks indemnification under Section 11.1 or 11.2, it shall inform the other party (the “Indemnifying Party”) of a claim as soon as reasonably practicable after it receives notice of the claim (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a claim as provided in this Section 11.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice), shall permit the Indemnifying Party to assume direction and control of the defense of the claim (including the right to settle the claim solely for monetary consideration) using counsel reasonably satisfactory to the Indemnified Party, and shall cooperate as requested (at the expense of the Indemnifying Party) in the defense of the claim. If the Indemnifying Party does not assume control of such defense within 30 days after receiving notice of the claim from the Indemnified Party, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all costs, including reasonable attorney fees, incurred by the Indemnified Party in defending itself within 30 days after receipt of any invoice therefor from the Indemnified Party. The party not controlling such defense may participate therein at its own expense. The party controlling such defense shall keep the other party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party. If the parties cannot agree as to the application of Section 11.1 or 11.2 to any claim, pending resolution of the dispute pursuant to Article 12, the parties may

conduct separate defenses of such claims, with each party retaining the right to claim indemnification from the other party in accordance with Section 11.1 or 11.2, as applicable, upon resolution of the underlying claim.

11.4 Insurance. Each party shall procure and maintain insurance, including comprehensive or commercial general liability insurance (including contractual liability and product liability), in amounts that are commercially reasonable in light of the activities and obligations undertaken by such party pursuant to this Agreement, which amounts shall be consistent with normal business practices of prudent companies similarly situated. It is understood that such insurance shall not be construed to create a limit of either party’s liability with respect to its indemnification obligations under this Article 11 or otherwise. Each party shall provide the other party with written evidence of such insurance upon request.

12. DISPUTE RESOLUTION

12.1 Disputes. Subject to Section 12.3, and except as expressly set forth in Article 3, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement (each, a “Dispute”) will be referred to Equillium’s Chair and Biocon’s Chair for attempted resolution. In the event the Chairs are unable to resolve such Dispute within 30 days of such Dispute being referred to them, then, upon the written request of either party to the other party, the Dispute shall be subject to arbitration in accordance with Section 12.2, except as expressly set forth in Section 12.3.

12.2 Arbitration.

(a) Claims. Subject to Section 12.3 below, any Dispute that is not resolved under Section 12.1 within the applicable 30-day period shall be resolved by final and binding arbitration administered by JAMS (the “Administrator”) in accordance with its then-effective Comprehensive Arbitration Rules and Procedures (the “Rules”), including its then-effective Expedited Procedures, except to the extent any such Rule conflicts with the express provisions of this Section 12.2. (Capitalized terms used but not otherwise defined in this Agreement shall have the meanings provided in the Rules.) The Arbitration shall be conducted by one neutral arbitrator (unless the parties mutually agree to have the Arbitration conducted by a panel of three neutral arbitrators), selected in accordance with the Rules, provided that no such individual shall be a current or former employee or director, or a current stockholder, of either party or any of their respective Affiliates (or any Sublicensee of the rights granted to such party under this Agreement). The arbitration and all associated discovery proceedings and communications shall be conducted in English, and the arbitration shall be held in New York City, New York. The Arbitrator(s) shall have the authority to grant preliminary or temporary injunctive relief pending the outcome of the Arbitration in the context of a bona fide emergency or prospective irreparable harm.

(b) Discovery. Within 30 days after selection of the Arbitrator(s), the Arbitrator(s) shall conduct the Preliminary Conference. In addressing any of the subjects within the scope of the Preliminary Conference, the Arbitrator(s) shall take into account both the desirability of making discovery efficient and cost-effective and the needs of the parties for an understanding of any legitimate issue raised in the Arbitration. In that regard, the parties agree to the application of the E-Discovery procedures set forth in Rule 16.2(c) of the JAMS Expedited Procedures.

(c) Hearing; Decision. The Arbitrator(s) shall require that each party submit concise written statements of position and shall permit the submission of rebuttal statements, subject to reasonable limitations on the length of such statements to be established by the Arbitrator(s). The Arbitrator(s) shall also permit the submission of expert reports. The Award shall include a written statement describing the essential findings and conclusions on which the Award is based, including the calculation of any damages awarded. The Arbitrator(s) will, in rendering their decision, apply the substantive law of the State of New York, USA, excluding its conflicts of laws principles with the exception of sections 5-1401 and 5-1402 of New York General Obligations Law. The Arbitrator’s(s’) authority to award special, incidental, consequential or punitive damages shall be subject to the limitation set forth in Section 9.9. The Award rendered by the Arbitrator(s) shall be final, binding and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction.

(d) Costs. Each party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the Arbitrator(s); provided, however, the Arbitrator(s) shall be authorized to determine whether a party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the Administrator and the Arbitrator(s).

12.3 Court Actions. Nothing contained in this Agreement shall deny either party the right to seek injunctive or other equitable relief, including specific performance, from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, including with respect to any breach of Article 8 or the ownership provisions of Section 7.1, and such an action may be filed and maintained notwithstanding any ongoing discussions between the parties or any ongoing arbitration proceeding. In addition, either party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity,

construction, scope, enforceability, infringement or other violations of Patent Rights or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 12.2.

13. GENERAL PROVISIONS

13.4 Non-Waiver.
