2.1.2 Retention of Rights. Notwithstanding the license granted in Section 2.1.1, Sigilon retains the rights under the Sigilon Know-How and Sigilon Patent Rights as necessary to conduct its Development and Manufacturing responsibilities with respect to Licensed Products hereunder in accordance with this Agreement (including any Sigilon Research Activities). In addition, Sigilon retains all rights under the Sigilon Know-How and Sigilon Patent Rights to research, develop, manufacture and commercialize any and all products other than Licensed Products (but subject to its obligations set forth in Section 2.4.1 and Article 9).

2.1.3 Sublicense Under MIT Patent Rights.

(a) Lilly understands and agrees that (i) the Sigilon Patent Rights licensed to Lilly pursuant to Section 2.1.1 include certain Patent Rights exclusively licensed to Sigilon pursuant to the Upstream License Agreement, (ii) the license under such Sigilon Patent Rights under Section 2.1.1 constitutes a sublicense under the Upstream License Agreement; and (iii) Lilly’s rights under such Sigilon Patents Rights are subject and subordinate to the terms and conditions of the Upstream License Agreement. The Upstream License Agreement is attached hereto as Schedule [***].

(b) Sigilon will reasonably enforce, or otherwise take the actions necessary to enable Lilly to enforce, Sigilon’s rights, benefits and the obligations of MIT under the Upstream License Agreement that may impact the rights, benefits and obligations of Lilly hereunder, including taking such actions as Lilly may reasonably request, and will inform Lilly of any action it may take under the Upstream License Agreement to the extent such action may impact Lilly’s interest under the Upstream License Agreement. Sigilon shall (1) fulfill all of its obligations, including its payment obligations, under, and shall not otherwise breach, the Upstream License Agreement; and (2) not amend or waive, or exercise any termination right, or omit to take any action that would alter, any of Sigilon’s rights under the Upstream License Agreement in any manner that adversely affects, or would reasonably be expected to adversely affect, Lilly’s rights, benefits and obligations under this Agreement. Sigilon shall promptly notify Lilly of any default under, termination or amendment of, the Upstream License Agreement, to the extent such default, termination or amendment may have an impact on Lilly. Without limiting the foregoing, Sigilon will not exercise its rights to stop paying patent costs under Section 6.1 of the Upstream License Agreement without obtaining Lilly’s prior written consent and Lilly shall have the right to elect to fund such patent costs. Sigilon will provide Lilly reasonable advance notice of its intent to cease any such funding and shall provide to Lilly any correspondence between Sigilon and MIT regarding such matter. If Lilly elects to fund such patent costs, then (i) Lilly shall have the right to offset any such costs that Lilly incurs against payments due to Sigilon hereunder, and (ii) notwithstanding anything to the contrary in this Agreement, any Patent Rights that Lilly is so funding shall be excluded from the definition of Sigilon Patent Rights for purposes of (A) Article 8 and (B) the Royalty Term definition.

(c) Notwithstanding anything to the contrary in this Agreement, in the event that the Upstream License Agreement is terminated and Lilly becomes a direct licensee of M.I.T. under the Upstream Patent Rights and enters into a new, direct license agreement with M.I.T. as provided for in Section 2.3 of the Upstream Licensed Agreement, Lilly shall have the right to [***], and without any limitation, by [***].

In the event that Lilly grants sublicenses to any Third Party and the scope of such rights is broader than enabling such Third Party to perform services, including distribution services, on behalf of Lilly or any Affiliate of Lilly (for example, the right to develop and commercialize Licensed Products in a given country in the Territory), it shall do so pursuant to a written sublicense agreement (each a “Sublicense Agreement”). Lilly shall provide Sigilon a copy of each Sublicense Agreement, for delivery to M.I.T., it being understood that [***] information may be redacted from such copy to the extent such information is not necessary to verify compliance hereunder and the terms, conditions and existence of such Sublicense Agreement shall be deemed the Confidential Information of Lilly.

with a contract service provider or a Party obtaining only a license to Develop Licensed Products (and not Commercialize Licensed Products) does not require Sigilon’s consent under the preceding sentence.

2.1.5 Rights of Reference. Sigilon hereby grants Lilly the right, exercisable from the Effective Date, to cross-reference Sigilon’s or its Affiliate’s Regulatory Filings and Regulatory Approvals anywhere in the world to the extent (a) cross referencing such Regulatory Filings and Regulatory Approvals is necessary or useful for Regulatory Approval of a Licensed Product (including any components thereof) and (b) such Regulatory Filings and Regulatory Approvals are Controlled by Sigilon or its Affiliates. In furtherance of the foregoing, Sigilon shall (or shall cause an applicable Affiliate to) provide a signed statement to this effect, if requested by Lilly, in accordance with U.S. 21 C.F.R. §314.50(g)(3) or the equivalent as required in any country or region of the Territory, or otherwise provide appropriate notification of such right of Lilly to the applicable Regulatory Authority.

2.1.6 Sigilon Covenant. Sigilon covenants that, during the Term, it will not: (a) take any action that would prevent or limit Lilly’s exercise of its rights under the exclusive license granted to Lilly under Section 2.1.1; or (b) assign, transfer, convey or otherwise grant to any Person: (i) any rights to any Sigilon Know-How and Sigilon Patent Right (or any rights to any intellectual property that would otherwise be included in the Sigilon Know-How or Sigilon Patent Rights if not assigned, transferred, conveyed or otherwise granted to a Third Party), in any manner that is inconsistent with the exclusive license granted to Lilly pursuant to Section 2.1.1; or (ii) any rights to any products that are inconsistent with the exclusive license granted to Lilly pursuant to Section 2.1.1.

Subject to Sections 4.1.2(c), 4.1.4(c) and 7.1.1(d), Sigilon will be responsible for all costs associated with such supply of Licensed Product for Sigilon Research Activities for the first Licensed Product. In addition, and subject to a successful quality audit of Sigilon (including key component suppliers) by Lilly (that is in addition to any other audit rights set forth in this Agreement) and the Parties entering into appropriate supply agreements and Quality Agreements no later than [***] of the Effective Date, Sigilon, except as provided below, will be responsible (at Sigilon’s sole cost and expense, but subject to Sections 4.1.4(c) and 7.1.1(d).) for the manufacture and supply of Licensed Product to Lilly for use in the first Phase 1 Clinical Trial for the first Licensed Product; provided, that Lilly will be solely responsible for determining the suitability of any materials (including Licensed Product or any component thereof) supplied by Sigilon or Sigilon’s Third Party suppliers and accepting or rejecting such materials for use in Lilly’s Clinical Trials. Lilly will determine, in accordance with applicable regulatory requirements, all Licensed Product quality standards for Licensed Product to be used in such Phase I Clinical Trial (or for any later Clinical Trial or commercial supply) including: stability; process validation and pre-approval inspection preparation; common specifications; assay methodology and storage conditions. Lilly will also determine in accordance with applicable regulatory requirements such Licensed Product quality standards that must be included in any manufacturing requirements for Licensed Product for such Phase 1 Clinical Trial.

7.3 Later Clinical and Commercial Supply of Encapsulation Material.

7.3.1 Licensed Product Supply. Following the IND Approval for the first Licensed Product and subject to Sigilon’s supply responsibilities under Section 7.2 and supply rights under Section 7.3.2 (including in the event that Sigilon fails the quality audit to be conducted by Lilly with respect solely to supply of Licensed Product for Phase 1 Clinical Trials under Section 7.2 but not with respect to its continued right to supply Encapsulation Material), Lilly will be responsible for the global supply chain including obtaining sufficient quantities of Islet Cells and final activities associated with encapsulating such Islet Cells with the Encapsulation Material and finishing the Licensed Product, for both clinical and Commercialization purposes. For clarity, the foregoing sentence means that Lilly will work directly with any Cell Line Provider or may identify alternative sources at its own sole discretion.

7.3.2 Encapsulation Material Supply.

(a) Sigilon Supply Rights. Notwithstanding the foregoing Section 7.3.1, subject to Section 7.3.2(b), Sigilon will have the right, and the obligation, to supply Lilly’s

requirements for the Encapsulation Material to be used in the manufacture of Licensed Products for clinical and Commercial use. In order for Sigilon to maintain such supply right, it shall be required to meet (or have its contract manufacturers meet) certain objective manufacturing readiness and regulatory and quality milestones appended to this Agreement as Schedule [***]. Sigilon’s supply of the Encapsulation Material shall be done pursuant to a clinical supply agreement and Quality Agreement to be entered into by the Parties, and a separate supply agreement and Quality Agreement for commercial supply, which will include appropriate supply contingency plans, define supply defaults and remedies therefor, and certain manufacturing and scale up matters and otherwise be consistent with the terms of this Agreement. Notwithstanding the foregoing, Lilly will be solely responsible for determining the suitability of the Encapsulation Materials supplied by Sigilon or Sigilon’s Third Party suppliers and accepting or rejecting such Encapsulation Material for use as a component in the manufacture of Licensed Product for use in Lilly’s Clinical Trials or for Commercial purposes. Sigilon will provide the Encapsulation Material to Lilly for clinical and Commercialization purposes at a price equal to [***] percent ([***]%) of its Manufacturing Costs therefor. Lilly shall have the right to audit Sigilon’s Manufacturing Costs by way of Section 8.3.4 applied mutatis mutandis (with appropriate substitution/replacement of relevant Party and subject matter references) or as otherwise provided for in the applicable supply agreement.

(b) Supply Failure. If Sigilon fails to satisfy the Supply Qualification Milestones, or Sigilon experiences a supply failure as defined under the applicable supply agreement, Lilly will have the right to (i) terminate (or reduce) Sigilon’s rights to supply Encapsulation Material to Lilly for clinical and commercial purposes, and (ii) enter into direct supply agreement and quality agreements to have manufactured the Encapsulation Material for use in the Manufacture of Licensed Products through one or more Third Party contract manufacturers acceptable to both Parties (such acceptance not to be unreasonably withheld, conditioned or delayed) for purposes of its entire requirements (or a portion thereof). If Sigilon satisfies the Supply Qualification Milestones, but defaults on its obligations (as defined under the Parties’ applicable supply agreements and Quality Agreements), Lilly will have the right to require that Sigilon either assign to Lilly its agreement with Sigilon’s third party manufacturer(s) of Encapsulation Material but only for use in the Manufacture of Licensed Products and/or designate one or more other Third Party contract manufacturers acceptable to Sigilon (such acceptance not to be unreasonably withheld, conditioned or delayed) for purposes of its entire requirements (or a portion thereof). In any such event, Sigilon shall conduct a manufacturing technology transfer as set forth in Section 7.5.

(c) Establishment of Second Source. At such time as Lilly desires to establish one or more secondary supply sources (independent of any supply failure), but in no event earlier than [***] it shall so inform Sigilon and Sigilon shall cooperate with Lilly in establishing and qualifying such second source, at Lilly’s cost and expense, including enabling such designated second source to manufacture such quantities of Encapsulation Materials as are necessary to ensure that any such facilities are able to immediately fulfill Lilly’s requirements for Encapsulation Material in the event that Lilly’s rights under Section 7.3.2(b) are triggered. In furtherance of the foregoing, Sigilon shall conduct a manufacturing technology transfer as set forth in Section 7.5 to enable such second source Third Party manufacturer referred to above in Section 7.3.2(b) to be qualified to manufacture Encapsulation Materials.

7.4 General Supply Terms. The terms and conditions set forth in this Section 7.4 may be augmented or otherwise revised as the Parties may agree in an applicable supply agreement or Quality Agreement.

7.4.1 Visits to Facilities. Without limiting Section 4.2.5 (which is specific to Agreement compliance-related audits), or Section 8.3.4 (which is specific to financial audits) and other Sections cross-referencing Section 8.3.4, Lilly shall have the right to conduct routine audits of Sigilon and its Third Party suppliers to ensure compliance with GMP during normal business hours no more than once annually (per facility at which Manufacturing is occurring) and only upon at least [***] days’ advance notice by Lilly and the mutual agreement of the Parties as to the specific date and time for such audit; provided, however, that in the case of audits for cause, or to determine GMP compliance, the once annual audit limit shall not apply and Lilly shall request such audit upon at least [***] days advance written notice. In addition, Sigilon will make all reasonable efforts to comply with requests for disclosure of information, including answering questionnaires and narrowly tailored audit inquiries, to enable Lilly to ensure compliance with all Applicable Laws, including anti-corruption laws, and this Agreement.

7.4.2 Notice of Inspections. Sigilon shall provide notice to Lilly within [***] business days of its receipt of any requested or commenced governmental or regulatory review, audit or inspection of its facility (or any of its Third Party suppliers), processes, Encapsulation Technology, or Encapsulation Material or Licensed Products. Sigilon shall provide Lilly with the results of any such review, audit or inspection. Lilly shall be given the opportunity to provide assistance to Sigilon in responding to any such review, audit or inspection.

7.5 Encapsulation Material Manufacturing Technology Transfer. If Lilly’s rights under Section 7.3 to have manufactured Encapsulation Material are triggered, upon Lilly’s written request, Sigilon will disclose or deliver to the agreed upon Third Party contract manufacturer, all Sigilon Know-How that is necessary or useful to enable such Third Party contract manufacturer to manufacture Encapsulation Material for use in the Manufacture of Licensed Products and Sigilon will provide reasonable technology transfer assistance in connection with the foregoing up to [***] hours per Calendar Year; provided that any hours spent in providing such assistance in excess of such [***] hours shall count against the number of hours of technical assistance to be provided by Sigilon under Section 5.6.

7.6 Finished Product Manufacturing Transfer. Without limiting Sigilon’s obligations under the Research Plan, upon Lilly’s request, Sigilon will disclose or deliver or otherwise make available to Lilly, or a contract manufacturer designated by Lilly (and under binder of confidentiality), all Sigilon Know-How pertaining to the finished Manufacture of Licensed Products incorporating the Islet Cells and Encapsulation Material that is necessary or useful to enable Lilly or a contract manufacturer to so conduct such finished manufacture of such Licensed Product and Sigilon will provide reasonable technology transfer assistance in connection with the foregoing up to [***] hours per Calendar Year; provided that any hours spent in providing such assistance in excess of such [***] hours shall count against the number of hours of technical assistance to be provided by Sigilon under Section 5.6.

8. CONSIDERATION

8.1 License Issuance Fee. In partial consideration of the rights granted by Sigilon to Lilly hereunder, Lilly shall pay to Sigilon a one-time, non-refundable and non-creditable license issuance fee of sixty-two million five hundred thousand U.S. Dollars (U.S. $62,500,000) within [***] days after the Effective Date.

8.2 Milestone Payments.

8.2.1 Regulatory Milestones. Lilly shall make the following one-time, non-refundable, non-creditable payments to Sigilon within [***] days after the first achievement of each of the following milestone events by each of the first [***] distinct Licensed Products (i.e., that is subject to a different IND and Drug Approval Application) to achieves each such milestone:

Milestone Event		Milestone Payment ($ US Dollars)
a)	[***]	$	[***]
b)	[***]	$	[***]

f)	[***]	$	[***]
g)	[***]	$	[***]
h)	[***]	$	[***]
i)	[***]	$	[***]

Notwithstanding the foregoing to the contrary, (i) the amount of any Milestone Payment payable upon achievement of a Milestone Event with respect to the second or third Licensed Product to achieve such Milestone Event shall be reduced by [***] percent ([***]%) of the amounts set forth above, (ii) Milestone Payment a) above shall only be payable with respect to the first Licensed Product, and (iii) Milestone Payment d) above shall be payable concurrently with Milestone Payment c) above if the applicable Phase II Clinical Trial constitutes a Pivotal Trial.

8.2.2 Sales Milestones. Lilly shall make the following one-time, non-refundable, non-creditable payments to Sigilon within [***] days after the first achievement of each of the

following milestone events as determined by aggregating Annual Net Sales of all Licensed Products:

Milestone Event	Milestone Payment ($ US Dollars)
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]

In the event two (2) or more sales Milestone Events are achieved in the same Calendar Year, Lilly shall pay to Sigilon each milestone payment corresponding to the respective Milestone Event, following the Calendar Quarter in which such sales milestone event occurred.

8.2.3 Notice and Payment of Milestones. Lilly shall provide Sigilon with prompt written notice upon the occurrence of each Milestone Event set forth in Section 8.2.1 and 8.2.2. If Sigilon believes any such Milestone Event has occurred and it has not received a written notice of same from Lilly, it shall so notify Lilly in writing and shall provide to Lilly documentation or other information that supports its belief.

8.3 Payment of Royalties; Royalty Rates; Accounting and Records.

8.3.1 Payment of Royalties. Lilly shall pay Sigilon royalties, on a Licensed Product-by-Licensed Product and country-by-country basis, on Annual Net Sales of each Licensed Product in each Calendar Year (or partial Calendar Year), commencing with the First Commercial Sale of such Licensed Product in any country in the Territory and ending upon the last day of the last Royalty Term for such Licensed Product, at the following incremental rates:

Annual Net Sales of such Licensed Product Increment		Royalty Rate (%)
For that portion up to [*]dollars ($[*])		[***]
For that portion greater than [*] dollars ($[]) but less than or equal to [] dollars ($[*])		[***]
For that portion greater than [*] dollars ($[]) but less than or equal to [] dollars ($[*])		[***]
For that portion greater than [*] dollars ($[]) but less than or equal to [] dollars ($[*])		[***]
For that portion greater than [*] dollars ($[*])		[***]

8.3.2 Adjustments to Royalty Payments.

(a) No Patent Coverage. Notwithstanding anything to the contrary in Section 8.3.1, if any Licensed Product is sold in a country and the composition of matter, a

Regulatory Authority-approved method of use, or the Encapsulation Material as a component of such Licensed Product is not Covered by a Valid Claim of a Sigilon Patent Right in such country, the royalty rates applicable to Net Sales in such country shall be reduced by [***] percent ([***]%) of the rates set forth in Section 8.3.1 above, continuing until the last day of the applicable Royalty Term with respect to such Licensed Product and such country at issue. The Parties hereby acknowledge and agree that royalties that are payable for a Licensed Product for which no Sigilon Patent Rights exist shall be in consideration of (i) Sigilon’s expertise and know-how concerning its development of the Sigilon Know-How and its other development activities conducted prior to the Effective Date; (ii) the rights granted to Lilly hereunder with respect to the Sigilon Know-How that are not within the claims of any Patent Rights Controlled by Sigilon; (iii) the restrictions on Sigilon in Section 2.4.1; and (iv) the “head start” afforded to Lilly by each of the foregoing.

(b) Third Party IP Payments.

(i) During the Term, Lilly will have the right to negotiate and obtain a license from one or more Third Parties, including any Third Party license to Patent Rights which Cover, or Know-How which is necessary to, the Encapsulation Material used in a given Licensed Product (or its use or manufacture), if in the absence of such a license the exploitation of the applicable Licensed Product in a manner consistent with using Lilly’s Commercially Reasonable Efforts to Develop, Manufacture and Commercialize the Licensed Product under this Agreement would, in Lilly’s good faith assessment and on advice of counsel, infringe or misappropriate such Third Party’s Patent Rights or Know-How (each such Third Party license is referred to herein as a “Third Party License”). Except as otherwise provided in this Agreement, any payments owed to any Third Party in consideration for such a Third Party License that are reasonably apportionable to the relevant Licensed Product (collectively, the “Third Party Payments”) shall be creditable against royalties payable to Sigilon under Section 8.3.1, provided that Lilly consulted with Sigilon with respect to such Third Party License and considered Sigilon’s comments in good faith, Lilly may take such credit during the Calendar Quarter for which royalties are payable hereunder; provided, that in no event will such credit reduce the royalties payable to Sigilon for such Calendar Quarter by more than [***] percent ([***]%); provided, further, that, any credit not applied because of such [***] percent ([***]%) reduction floor may be carried forward to future Calendar Quarters. For clarity, Lilly shall not have the right to offset pursuant to this Section 8.3.2(b)(i) any amounts paid by it, whether in the form of a patent or know-how royalty or milestone or other payment, for access to, supply, use, manufacture, or development of cell lines for Islet Cells or in connection with the use of any Differentiation Protocol.

(ii) In the event that Sigilon disputes Lilly’s determination that any Third Party Payments are properly subject to the royalty offset provided under this Section 8.3.2(b) or Lilly’s allocation of any such Third Party Payments to a Licensed Product, Sigilon may by written notice to Lilly require that such dispute be resolved in accordance with Section 15.1 of this Agreement; provided that Lilly shall have the right to take royalty reductions pursuant to this Section 8.3.2(b) pending resolution of any such dispute; provided further, that if any such dispute is resolved in favor of Sigilon, then within [***] days of such resolution, Lilly shall pay to Sigilon any adjustment in royalties due pursuant to this Section 8.3.2(b) as required by such resolution.

(iii) This Section 8.3.2(b) shall not apply to any Third Party Payments payable by Lilly or any of its Affiliates or Sublicensees under any license or other agreement or understanding, written or oral, between Lilly or any of its Affiliates or Sublicensees, on the one hand, and any Third Party, on the other hand, in existence as of the Effective Date.

(iv) As between the Parties, Sigilon shall be solely responsible for any and all payments owed pursuant to the Upstream License Agreement resulting from any activities with respect to Licensed Products under this Agreement, including any payments of milestones or royalties with respect thereto. Furthermore, as between the Parties, Sigilon shall be solely responsible for any and all payments including, Third Party Payments, payable by Lilly or any of its Affiliates or Sublicensees under any license or other agreement or understanding, written or oral, between Sigilon or any of its Affiliates or (sub)licensees, on the one hand, and any Third Party, on the other hand, in existence as of the Effective Date.

(c) Limit on Royalty Reductions. Notwithstanding anything to the contrary in [***], in no event shall the royalties owed under Section 8.3.1 with respect to a Licensed Product in a country be reduced by operation of Section 8.3.2(a) and (b) by more than [***] percent ([***]%) of what would otherwise be owed under Section 8.3.1 with respect to such Licensed Product in such country. For purposes of clarity, this limitation [***].

(d) Competing Generic. In the event that one or more Third Parties sells a Competing Generic (as defined below) in any Calendar Quarter in any country in which a Licensed Product is then being sold by Lilly, then, (i) if only one Third Party is selling a Competing Generic in such country during such Calendar Quarter, the applicable royalties in effect with respect to such Licensed Product in such country as specified in Section 8.3.1 shall be reduced by [***] percent ([***]%); (ii) if only two Third Parties are selling Competing Generics in such country during such Calendar Quarter, the applicable royalties in effect with respect to such Licensed Product in such country as specified in Section 8.3.1 shall be reduced by [***] percent ([***]%); and (iii) if three or more Third Parties are selling Competing Generics in such country during such Calendar Quarter, the applicable royalties in effect with respect to such Licensed Product in such country as specified in Section 8.3.1 shall be reduced by [***] percent ([***]%). For purposes of this Section 8.3.2(d), a “Competing Generic” means, with respect to a given Licensed Product and a given country in the Territory, a product sold by a Third Party in such country, other than as a Sublicensee of Lilly or its Affiliates under this Agreement, that (x) receives Marketing Authorization as a generic, follow-on, hybrid, biosimilar, or interchangeable product of such Licensed Product from the applicable Regulatory Authority in such country by referencing the Drug Approval Application (or data therein) for the Licensed Product or (y) which is approved under an abbreviated pathway under the BPCI Act or similar legislation in the relevant country.

8.3.3 Payment Dates and Reports. Royalty payments shall be made by Lilly with respect to each Licensed Product within [***] days after the end of each Calendar Quarter in which a sale of such Licensed Product shall occur, commencing with the Calendar Quarter in which the First Commercial Sale of such Licensed Product occurs. Lilly shall also provide, at the same time each such payment is made, a report showing: (a) the Net Sales of each Licensed Product by type of Licensed Product and country in the Territory; (b) the applicable royalty rates for any Licensed Product in each country in the Territory; and (c) a calculation of the amount of royalty due to Sigilon.

8.3.4 Records; Audit Rights. Lilly and its Affiliates and Sublicensees shall keep and maintain for [***] years from the end of the Calendar Year in which Net Sales occurred (the “Retention Period”) complete and accurate records of gross sales and Net Sales by, as applicable, Lilly and its Affiliates and Sublicensees of each Licensed Product, in sufficient detail to allow royalties to be determined accurately. Sigilon shall have the right during the applicable Retention Period to appoint at its expense a nationally recognized independent certified public accountant reasonably acceptable to Lilly to audit the relevant records of Lilly and its Affiliates and Sublicensees to verify that the amount of such payment was correctly determined. Lilly and its Affiliates and Sublicensees shall each make its records available for audit by such nationally recognized independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon [***] days’ written notice from Sigilon. Such audit right shall not be exercised by Sigilon more than once in any Calendar Year or more than once with respect to sales of a particular Licensed Product in a particular period. All records made available for audit shall be deemed to be Confidential Information of Lilly. The results of each audit, if any, shall be binding on both Parties absent manifest error. In the event there was an underpayment by Lilly hereunder, Lilly shall promptly (but in any event no later than [***] days after Lilly’s receipt of the report so concluding) make payment to Sigilon of any shortfall. Sigilon shall bear the full cost of such audit unless such audit discloses an underreporting by Lilly of [***] percent ([***]%) and at least $[***] of the aggregate amount of royalties payable in any Calendar Year, in which case Lilly shall reimburse Sigilon for all reasonable costs incurred by Sigilon in connection with such audit. In the event there was an overpayment by Lilly hereunder, Sigilon shall promptly (but in any event no later than [***] days after Sigilon’s receipt of the report so concluding) make repayment to Lilly of any such overage.

8.3.5 Overdue Payments. All payments not made by Lilly to Sigilon when due under this Agreement shall bear a simple interest at a rate equal to the lesser of the [***]-day LIBOR rate as quoted by the Wall Street Journal (eastern edition) on the date that payment is due or the maximum interest rate permitted by Applicable Laws. Any such overdue payment shall, when made, be accompanied by, and credited first to, all interest so accrued.

8.3.6 Payments; Withholding Tax.

(a) Payments in Dollars. All payments made by Lilly under this Article 8 shall be made by wire transfer from a banking institution in US Dollars in accordance with instructions given in writing from time to time by Sigilon, provided however that Lilly will disburse payments only to Sigilon’s jurisdiction of incorporation or to a jurisdiction in which Sigilon has a significant business presence.

(b) Withholding Taxes. If Applicable Laws require withholding of income or other taxes imposed upon any payments made by Lilly to Sigilon under this Agreement, including any VAT or sales tax, Lilly shall (i) make such withholding payments as may be required, (ii) subtract such withholding payments from such payments, (iii) submit appropriate proof of payment of the withholding taxes to Sigilon within a reasonable period of time, and (iv) promptly provide Sigilon with all official receipts with respect thereto. Lilly shall render Sigilon reasonable assistance in order to allow Sigilon to obtain the benefit of any present or future treaty against double taxation which may apply to such payments.

9. TREATMENT OF CONFIDENTIAL INFORMATION; PUBLICITY.

9.1 Confidentiality.

9.1.1 Confidentiality Obligations.

(a) Sigilon and Lilly each recognizes that the other Party’s Confidential Information and Proprietary Materials constitute highly valuable assets of such other Party. Sigilon and Lilly each agrees that, during the Term and for an additional [***] years after termination or expiration of this Agreement, (a) subject to Section 9.1.2, it will not disclose, and will cause its Affiliates not to disclose, any Confidential Information or Proprietary Materials of the other Party, (b) it will not use, and will cause its Affiliates not to use, any Confidential Information or Proprietary Materials of the other Party, except as expressly permitted in this Agreement, (c) it shall not attempt to reverse engineer, deconstruct or in any way determine the structure or composition of any of the other Party’s Proprietary Materials (provided, that it is understood that the foregoing shall not apply to any Encapsulation Materials), and (d) it will use the same efforts to protect the other Party’s Confidential Information as it does to protect its own similar Confidential Information (but, in any event, no less efforts than a reasonable Person in the industry would use to protect similar information). To the extent that any Confidential Information or Proprietary Materials are identified in writing as a “trade secret” by either Party, the other Party’s obligations of confidentiality and non-use with respect to such trade secret information shall continue for so long as the relevant Confidential Information remains a “trade secret.”

(b) Notwithstanding the foregoing Section 9.1.1(a), or anything to the contrary in this Agreement:

(i) the Parties acknowledge the practical difficulty of policing the use of information in the unaided memory of the Receiving Party or such Receiving Party’s officer, director, employee, or agent who have had access to such Confidential Information, and as such, each Party agrees that the Receiving Party shall not be liable for the use by any of its permitted officers, directors, employees, or agents of specific Confidential Information of the Disclosing Party that is retained in the unaided memory of such officer, director, employee, or agent; provided that (1) the foregoing is not intended to grant, and shall not be deemed to grant, the Receiving Party, its Affiliates, or its officers, directors, employees, and agents (A) a right to disclose the Disclosing Party’s Confidential Information, or (B) a license under any Patent Rights of the Disclosing Party; and (2) such officer, director, employee, or agent has not intentionally memorized such Confidential Information for use outside this Agreement; and

(ii) except to the extent Sigilon has granted exclusive rights to Lilly under Section 2.1 (including as and to the extent such rights survive this Agreement), neither Party is forfeiting any rights that each may have to perform research activities covered by the patent rights of the other Party in compliance with 35 U.S.C. § 271(e)(1) or any experimental or research use exemption that may apply in any country.

9.1.2 Limited Disclosure. Each Disclosing Party agrees that disclosure of its Confidential Information or any transfer of its Proprietary Materials may be made by the Receiving Party to any employee, director or agent of, or consultant to, such Receiving Party or to other Third

Parties to enable such Receiving Party to exercise its rights (including Lilly’s right to Develop, Manufacture, or Commercialize the Licensed Product under the license granted to it under Section 2.1 of this Agreement) or to carry out its responsibilities under this Agreement; provided, that, any such disclosure or transfer shall only be made to Persons who are bound by written obligations of confidentiality and non-use at least as strict as those described in Article 9. In addition, each Disclosing Party agrees that the Receiving Party may disclose Confidential Information of the Disclosing Party (a) on a need-to-know basis to such Receiving Party’s professional, legal and financial advisors, (b) as reasonably necessary in connection with an actual or potential (i) permitted license or sublicense of such Receiving Party’s rights hereunder, (ii) financing of such Receiving Party in a public or private offering, or (iii) merger, acquisition, consolidation, share exchange or other similar transaction involving such Receiving Party and any Third Party, (c) to any Third Party that is or may be engaged by a Receiving Party to perform services in connection with the Research Plan (or perform services in connection with carrying out Development or Commercialization activities) as necessary to enable such Third Party to perform such services, and (d) for any other purpose with the Disclosing Party’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that, any such disclosure or transfer shall only be made to Persons who are bound by written obligations of confidentiality and non-use at least as strict those as described in Article 9, except for any disclosures to any actual or potential bona fide potential financial investor (which financial investor does not include any pharmaceutical company or any venture fund related thereto or any other company owning or controlling any products for use in the Field), which may be done pursuant to written obligations of confidentiality for durations of no less than [***] years. Each Disclosing Party further agrees that the Receiving Party may disclose such Disclosing Party’s Confidential Information or provide such Disclosing Party’s Proprietary Materials (A) as reasonably necessary to file, prosecute or maintain Patent Rights, or to file, prosecute or defend litigation related to Patent Rights, or to file or maintain a Regulatory Filing, in accordance with this Agreement or (B) as required by Applicable Laws (including securities laws or regulations and the applicable rules of any public stock exchange in the case of any initial public offering or subsequent public offering or in response to rules or guidance of the United States Internal Revenue Service or other taxing authority, or in other legal processes, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or other securities trading institution.

9.1.3 Requirement to Cooperate to Enable Accurate Public Disclosure. To the extent either Party discloses to the other Party any Confidential Information which is a fact, result or event relating to the Research Activities or the Development, Manufacture or Commercialization of any Licensed Product that the Receiving Party in good faith reasonably believes is insufficient to allow the Receiving Party to fully understand the materiality of such Confidential Information for purposes of determining whether the Receiving Party is required to disclose, to any Government Authority or publicly, any such Confidential Information in order to comply with Applicable Laws (including securities laws or regulations and the applicable rules of any public stock exchange), the Disclosing Party agrees to discuss such Confidential Information with the Receiving Party and provide any additional information reasonably necessary to enable the receiving Party to assess the materiality, and the accuracy and completeness, of such information for such public disclosure purposes as the case may be, which additional information shall be treated as the Disclosing Party’s additional Confidential Information and shall be treated in accordance with the terms hereof.

9.1.4 Employees and Consultants. Sigilon and Lilly each hereby represents and warrants that all of its employees, directors, agents and consultants, and all of the employees and consultants of its Affiliates and relevant Third Parties, who have access to Confidential Information or Proprietary Materials of the other Party are or will, prior to having such access, be bound by written obligations of confidentiality and non-use at least as strict those as described in Article 9. Each Party agrees to use, and to cause its Affiliates and relevant Third Parties to use, commercially reasonable efforts to enforce such obligations and to prohibit its employees, directors, agents and consultants from using such Confidential Information except as expressly permitted hereunder.

9.2 Publicity.

9.2.1 Press Releases. The Parties shall, upon such timing as the Parties jointly agree (but in any event, within [***] days after execution of this Agreement), issue a joint press release with respect to this Agreement including provisions listed in Schedule [***], and each Party may make subsequent public disclosure of the contents of such press release without further approval of the other Party. Subject to the foregoing, except as otherwise permitted under this Article 9, neither Party shall issue a press or news release or make any similar public announcement related to the Research Plan or the terms and conditions of this Agreement without the prior written consent of the other Party, not to be unreasonably withheld. If a Party determines the need to make an announcement related to this Agreement (as distinct from a publication related to a Licensed Product, which is subject to Section 9.2.2) is required by Applicable Laws, it shall, to the extent reasonably practicable and permitted, give the other Party at least [***] business days advance notice of the text of the announcement so that the other Party will have an opportunity to comment upon the announcement. With respect to any such public disclosure, except for the initial press release described above, the receiving Party (the “Requesting Party”) shall provide the other Party (the “Reviewing Party”) with: (a) a draft of the Content (as defined in the next sentence) of the draft press release or Required Filing for review, at least [***] business days (if practicable under the circumstances, or if not practicable, such shorter time) in advance of the issuance of the press release or filing. The word “Content” in this Section 9.2.1 means any information relating to the activities contemplated by this Agreement, and does not include any other business information of the Requesting Party or information pertaining to the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 relating to “forward-looking statements.” The Reviewing Party may notify the Requesting Party of any reasonable objections or suggestions that the Reviewing Party may have regarding the Content in the proposed public disclosure provided for review, and the Requesting Party shall reasonably consider any such objections or suggestions that are provided in a timely manner. The Requesting Party shall use diligent and good faith efforts to adopt the reasonable requests of the Reviewing Party with respect to its Confidential Information.

9.2.2 Right to Publish/Present Publications.

(a) Notwithstanding the foregoing or anything to the contrary in this Agreement, the Parties shall mutually agree on the timing and content of any publications or public presentations with respect to any results achieved prior to the Research Completion Date, and which Party is the more appropriate to prepare the initial draft of any such publication or presentation materials, for review and comment by the other Party, it being understood that each

Party shall have the right to ensure that its Confidential Information or Know-How is not included in such publication or presentation materials.

(b) Notwithstanding the foregoing or anything to the contrary in this Agreement, except as set forth in the last sentence of this Section 9.2.2(b) and as provided in Section 9.1.2 and 9.2.3, Lilly shall have the sole right to publish or publicly present all results or any and all milestone events achieved with respect to the research, Development, Manufacture or Commercialization of any Licensed Product conducted following the Research Completion Date; provided, that, to the extent such publication contains Sigilon Know-How or Sigilon’s Confidential Information, (a “Publication”), Lilly shall submit a draft of any such Publication to Sigilon prior to any such submission for publication or oral presentation and Sigilon shall have the right to notify Lilly in writing within [***] business days of receipt of such draft if it reasonably determines that such draft (i) contains Sigilon Know-How that is Confidential Information of Sigilon, in which case Lilly shall remove such Confidential Information from the proposed press release, manuscript, abstract or speech.

Third Party of an application for approval of a biosimilar under the BPCI Act, or similar legislation outside the United States, for any Licensed Product (each, an “Infringement”), that Party shall promptly notify the other Party of such Infringement of which it is aware (each, an “Infringement Notice”). The Parties shall promptly meet to discuss the Infringement and the strategy for patent enforcement with respect to that Infringement; provided, that, at the request of either Party, the Parties shall first execute a common interest agreement before any such meetings or exchange of detailed information.

(ii) Sigilon shall have the first right, but not the obligation, to address any such Infringement in the Territory with respect to the Sigilon Other Patent Rights, or with respect to the Sigilon Know-How, taking reasonable steps, which may include the institution of legal proceedings or other action, and to compromise or settle such Infringement (each, an “Infringement Response”); provided, that: (A) Sigilon shall keep Lilly reasonably informed about any such Infringement Response and Lilly shall provide all reasonable cooperation to Sigilon in connection with such Infringement Response; (B) Sigilon shall not take any position with respect to, or compromise or settle, any such Infringement that relates to a Sigilon Other Patent Right or Sigilon Know-How in any way that is reasonably likely to directly and adversely affect the scope, validity or enforceability of any such Sigilon Other Patent Right, without the prior consent of Lilly, which consent shall not be unreasonably withheld, conditioned or delayed; provided however that the foregoing shall not apply to settlement of any Infringement solely of patent claims within any Sigilon Other Patent Right that do not Cover the Licensed Product (such Infringement, an “Excepted Infringement”); and (C) if Sigilon does not intend to prosecute or defend an Infringement (other than an Excepted Infringement) of Sigilon Other Patent Rights or Sigilon Know-How, or ceases to diligently pursue an Infringement Response with respect to such an Infringement of Sigilon Other Patent Rights or Sigilon Know-How, it shall promptly inform Lilly in such a manner that such Infringement Response will not be prejudiced and Section 11.2.1(a)(iii) shall apply. All costs, including attorneys’ fees, relating to any Infringement Response undertaken by Sigilon shall be borne solely by Sigilon.

(iii) Lilly shall have the first right, but not the obligation, to address any Infringement in the Territory with respect to the Lilly Patent Rights, Sigilon Program Patent Rights, or Joint Patent Rights, or with respect to the Lilly Know-How, taking reasonable steps to initiate an Infringement Response, provided, that: (A) Lilly shall keep Sigilon reasonably informed about any such Infringement Response and Sigilon shall provide all reasonable cooperation to Lilly in connection with such Infringement Response; and (B) if Lilly does not intend to prosecute or defend an Infringement of such Patent Rights, or ceases to diligently pursue an Infringement Response with respect to such an Infringement of Sigilon Program Patent Rights, Lilly Program Patent Rights or Joint Patent Rights, it shall promptly inform Sigilon in such a manner that such Infringement Response will not be prejudiced and Section 11.2.1(a)(ii) shall apply.

For clarity, the settlement of an Infringement

Response may involve entering into a Third Party License, which would be subject to Section 8.3.2(b).

(b) Right to Representation. Each Party shall have the right to participate and be represented by counsel that it selects, in any Infringement Response (other than to an Excepted Infringement) instituted or continued under Section 11.2.1(a)(ii) or (iii) by the other Party. If a Party with the right to initiate an Infringement Response under Section 11.2.1(a) to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such action, then the Party with the right to initiate an action under Section 11.2.1(a) may name the other Party as plaintiff in such action or may require the Party with standing to initiate such Infringement Response at the expense of the other Party.

Any settlements, damages or monetary awards (“Recovery”) recovered by either Party pursuant to any Infringement Response (other than to an Excepted Infringement) shall, after reimbursing the Parties for their reasonable out-of-pocket expenses in making such recovery, be retained by or paid to Lilly and Sigilon, on a [***] percent ([***]%) (Lilly) to [***] percent ([***]%) (Sigilon) basis.

(e) Upstream Patent Rights. Any Infringement of any Upstream Patent Rights shall be subject to M.I.T.’s first right to respond to any such infringement and enforce such Upstream Patent Right. Sigilon shall keep Lilly reasonably informed about any such Infringement and the response thereto, unless such Infringement relates only to claims within the Upstream Patent Rights which do not Cover a Licensed Product, and Lilly shall provide all reasonable cooperation to Sigilon in connection with such Infringement response, at Sigilon’s expense. To the extent within its control, Sigilon shall not take any position with respect to, or compromise or settle, any such Infringement of Upstream Patent Rights in any way that is reasonably likely to directly and adversely affect the scope, validity or enforceability of any such Upstream Patent Rights Covering the Licensed Product without the prior consent of Lilly, which consent shall not be unreasonably withheld, conditioned or delayed.

11.3 Defense of Claims. If any action, suit or proceeding is brought against either Party or any Affiliate of either Party alleging the misappropriation or infringement of the Know-How or Patent Rights of a Third Party by reason of the research, Development, Manufacture or Commercialization of any Licensed Product, such Party shall notify the other Party within [***] days of the earlier of (a) receipt of service of process in such action, suit or proceeding, or (b) the date such Party becomes aware that such action, suit or proceeding has been instituted and the Parties shall meet as soon as possible to discuss the overall strategy for defense of such matter. Except as unanimously agreed by the Parties, prior to the Research Completion Date, Sigilon shall have the right but not the obligation to defend any such action, suit or proceeding brought against it, at its sole expense, and after the Research Completion Date, Lilly shall have the right but not the obligation to defend any such action, suit or proceeding at its sole expense; (b) the Party not

defending such action, suit or proceeding shall have the right to separate counsel at its own expense in any such action, suit or proceeding; and (c) the Parties shall cooperate with each other in all reasonable respects in any such action, suit or proceeding. Each Party shall promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party including all documents filed in any litigation.

11.4 Patent Term Extension. The Parties shall cooperate with each other in obtaining patent term extensions or supplemental protection certificates or their equivalents in any country in the Territory where applicable to any Patent Right Covering the Licensed Product. Such cooperation shall include diligently and timely conferring and coordinating with respect to such matters to ensure compliance with applicable filing deadlines, and agreeing on procedures to be followed by the Parties to ensure such compliance. In the event that elections with respect to obtaining such patent term extension are to be made or the Parties otherwise disagree, Lilly shall have the right to make the election or decision to the extent it involves a Lilly Patent Right, Sigilon Program Patent Right or Joint Patent Right.

(h) Notwithstanding the foregoing Section 12.3, in the event that Lilly terminates this Agreement pursuant to Section 12.2.1, as a condition precedent to Sigilon receiving the transfer of any rights under clauses (b) through (f) inclusive, above, Sigilon shall be required to inquire, within [***] days of receipt of notice of termination, if Lilly’s determination to terminate is for safety reasons (as defined below), and if Lilly so informs Sigilon that its termination was in fact for such safety reasons, or if Sigilon does not inquire within such [***] day period, then Sections 12.3(a) through (g), inclusive, shall be of no force or effect and Lilly will be responsible for winding-down any on-going activities, in accordance with accepted pharmaceutical industry norms and ethical practices, and Lilly’s licenses will survive to the extent necessary to perform such activities. For purposes of this Section 12.3(h), “safety reasons” shall mean that the medical risk/benefit of the Licensed Product is so unfavorable that it would be incompatible with the welfare of patients to develop or commercialize or to continue to develop or commercialize the Licensed Product

(i) If Sigilon elects to receive any of the rights set forth in clauses (c), (d), or (e) above (to the extent they apply and are not unavailable in accordance with clause (h) above), such remedy shall be Sigilon’s exclusive remedy resulting from any such termination.

12.4 Consequences of Termination of Agreement Caused by Sigilon. If this Agreement is terminated or terminable by Lilly pursuant to Section 12.2.2, 12.2.3 or 12.2.4, then, at Lilly’s discretion, either:

(a) the Parties shall agree on a wind-down plan, which may include Lilly transitioning on-going activities or granting rights or licenses to Sigilon on terms and conditions to be agreed by the Parties, including appropriate compensation for the relative contributions of the Parties. In the event that Sigilon does not desire to take over any activities

being conducted by Lilly on the effective date of termination, Lilly will be responsible for winding-down such activities, in accordance with accepted pharmaceutical industry norms and ethical practices, and Lilly’s licenses will survive to the extent necessary to perform such activities. All rights and licenses granted by one Party to the other Party in Article 2 will terminate. Any such termination of this Agreement will automatically result in a Sublicensee stepping into Lilly’s position under this Agreement (subject only to the scope being modified to be co-extensive with rights such Sublicensee was granted by Lilly and with complementary pro rata modifications to the financial terms of this Agreement and so obligations beyond those in this Agreement and subject to such Sublicensee not being as of such time in breach of its sublicense agreement with Lilly); or

(b) in lieu of exercising such termination right, Lilly shall have the right, by way of written notice to Sigilon, to continue this Agreement in accordance with its terms subject to reducing all payments (other than any Costs for which Lilly is responsible under Section 4.1.4(c) due from Lilly to Sigilon hereunder by [***] percent ([***]%). Any such remedy shall be Lilly’s exclusive remedy resulting from any such termination.

12.5 Surviving Provisions. Termination or expiration of this Agreement for any reason shall be without prejudice to: (a) the survival of rights specifically stated in this Agreement to survive, including as set forth in this Section 12.5; (b) the rights and obligations of the Parties provided in Sections 2.2.2 and 2.2.3 (except in the event of a termination of this Agreement by Lilly in accordance with Sections 12.2.2, 12.2.3 or 12.2.4), 2.3, 7.1.3, 8.3 (with respect to amounts accruing prior to the effective date of expiration or termination), 9.1.1 (for the period set forth in Section 9.1.1(a) and the last sentence of Section 9.1.1(a)), 9.1.1(b)(i), 10.1, 10.2, 12.3 or 12.4 (as and to the extent applicable), and this Section 12.5, and Articles 1 (to the extent necessary to give effect to other surviving provisions), 14, and 15, all of which shall survive such termination or expiration, except as provided in this Article 12; and (c) any other rights or remedies provided at law or equity which either Party may otherwise have, except as otherwise expressly provided for in this Agreement.

To the extent such rules are inconsistent with this provision, this provision will control.

(a) any demand for arbitration must be made in writing to the other Party.

(b) The arbitration panel will be composed of three (3) arbitrators, one of whom shall be appointed by each Party. The Parties shall appoint their respective arbitrators within [***] days after submission for arbitration. The two (2) arbitrators so appointed shall agree on the appointment of the third arbitrator from the list of arbitrators maintained by the American Arbitration Association. If the Parties’ appointed arbitrators shall fail to agree within [***] days from the date both Parties’ arbitrators have been appointed, on the identity of the third arbitrator, then such arbitrator shall be appointed by the appropriate administrative body of the American Arbitration Association

(c) The seat of the arbitration will be New York, New York.

Each of the Parties hereby agrees that, in the event of any such breach or threatened breach, in addition to all other available remedies hereunder, the non-breaching Party shall have the right, through the arbitration process described in this Section 15.1.3, to seek equitable relief to enforce the provisions of this Agreement.

15.1.4 No Arbitration of Patent or Antitrust Matters.

This Agreement has been prepared in the English language and the English language shall control its interpretation. In addition, all notices required or permitted to be given hereunder, and all written, electronic, oral or other communications between the parties regarding this Agreement shall be in the English language.

15.11 Integration; Severability. This Agreement and the warrant set forth the entire agreement with respect to the subject matter hereof and thereof and supersede all other agreements and understandings between the Parties with respect to such subject matter. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties with respect to the subject matter of this Agreement other than as are set forth in this Agreement and any other documents delivered pursuant hereto or thereto. If any provision of this Agreement is or becomes invalid or is ruled invalid by any court of competent jurisdiction or is deemed unenforceable, it is the intention of the Parties that the remainder of the Agreement shall not be affected.

15.12 Further Assurances. Each of Sigilon and Lilly, upon the request of the other Party, whether before or after the Effective Date and without further consideration, will do, execute, acknowledge, and deliver or cause to be done, executed, acknowledged or delivered all such further acts, deeds, documents, assignments, transfers, conveyances, powers of attorney, instruments and assurances as may be reasonably necessary to effect complete consummation of the transactions contemplated by this Agreement, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. The Parties agree to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be reasonably necessary in order to consummate or implement expeditiously the transactions contemplated by this Agreement.

15.13 Expenses. Each of the Parties will bear its own direct and indirect expenses incurred in connection with the negotiation and preparation of this Agreement and, except as set forth in this Agreement, the performance of the obligations contemplated hereby and thereby.

15.14 Intellectual Property. The parties acknowledge and agree that the licenses granted by the Parties and all other rights granted under or pursuant to this Agreement are and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code (or analogous provisions of the bankruptcy laws of any Governmental Authority), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code (or analogous foreign provisions), and that this Agreement is an executory contract governed by Section 365(n) of the Bankruptcy Code (or analogous foreign provisions) in the event that a bankruptcy proceeding is commenced involving either party. Lilly, as the licensee of such rights under Section 2.1, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code. The foregoing provisions of this Section 15.14 are without prejudice to any rights the parties may have arising under the Bankruptcy Code or other Applicable Laws.

15.15 Performance by Affiliates. Lilly may discharge any obligation and exercise any right hereunder through any of its Affiliates. Lilly hereby guarantees the performance by its Affiliates of such obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by an Affiliate of Lilly of any of Lilly’s obligations under this Agreement shall be deemed a breach by Lilly, and Sigilon may proceed directly against Lilly without any obligation to first proceed against such Affiliate.

15.16 Other Activities. The Parties acknowledge that, except as expressly provided in this Agreement, each of them may now or in the future engage in research, manufacturing, development or commercialization activities that utilize technologies similar to or involve products competitive with those contemplated by this Agreement. The Parties acknowledge that, except as expressly provided in this Agreement, each of them may now or in the future engage in research, manufacturing, development or commercialization activities that utilize technologies similar to or involve products competitive with those contemplated by this Agreement. Except as may be expressly provided in this Agreement, nothing in this Agreement, including any obligation to promote Licensed Products or any restriction on the use of Confidential Information, shall create any obligation to utilize a separate sales force for Licensed Products from that used for other products. Subject to the exclusivity provisions of Section 2.4 (as applicable), neither Party shall be prevented from using any publicly available research results or other information (including any publicly available information of the other Party) to the same extent as Third Parties generally are legally permitted to do so. Each Party agrees that the other Party has limited resources, and as a result it is anticipated that personnel assigned to the activities contemplated by this Agreement may also participate in other activities that may utilize technologies similar to or involve products competitive with those contemplated by this Agreement. In particular, it is anticipated that personnel in sales, marketing, clinical and regulatory functions, regardless of level, will participate in multiple programs and that management personnel will by nature of their leadership positions participate in multiple programs.
