 Exhibit 10.4 

RESTRICTED STOCK PURCHASE AGREEMENT 

This Restricted Stock Purchase Agreement (this “Agreement”) dated as of
                , (the “Effective Date”), is made by and between Eleven Biotherapeutics, Inc., a Delaware corporation (the “Company”),
and                  (“Purchaser”). 

WHEREAS, the Company desires to sell to Purchaser, and Purchaser desires to purchase from the Company,
                 shares (the “Shares”) of the Company’s Common Stock, $0.001 par value per share (“Common Stock”). 

NOW, THEREFORE, in consideration of the premises and the promises set forth herein, and for other good and valuable consideration, the parties
agree as follows: 
 1. Definitions. As used in this Agreement, the following terms shall have the following meanings: 

Act: The Securities Act of 1933, as amended. 

Qualified Sale: The sale of all or substantially all of the assets or issued and outstanding capital stock of the Company, or merger or
consolidation involving the Company in which stockholders of the Company immediately before such merger or consolidation do not own immediately after such merger or consolidation capital stock or other equity interests of the surviving corporation
or entity representing more than fifty percent in voting power of capital stock or other equity interests of such surviving corporation or entity outstanding immediately after such merger or consolidation. 

Shares: The shares of Common Stock issued to Purchaser hereunder and any other securities of the Company which may be issued in
exchange for or in respect of such shares of Common Stock, whether by way of stock split, stock dividend, combination of shares, reclassification, recapitalization, reorganization or any other means. 

2. Purchase and Sale of Shares. Pursuant to the terms and conditions set forth in this Agreement, the Company hereby sells to
Purchaser, and Purchaser hereby purchases from the Company,                  shares of the Company’s Common Stock for a purchase price per share of
$        , and an aggregate purchase price of $        . The Company acknowledges receipt from Purchaser of $        , in full
payment of such purchase price. Purchaser and the Company hereby agree the fair market value of the Shares on the date hereof is $         per share. 

3. Representations of Purchaser. Purchaser represents to the Company, and agrees that the Company is entitled to rely on such
representations, as follows: 
 (a) Purchaser understands that the Shares have not been registered under the Act, or registered or qualified
under the securities or “Blue Sky” laws of any jurisdiction, and are being sold pursuant to exemptions contained in the Act and exemptions contained in other applicable securities or “Blue Sky” laws. Purchaser understands further
that the Company’s reliance on these exemptions is based in part on the representations made by Purchaser in this Agreement. In this connection, Purchaser represents and warrants that the offer and sale of the Shares were made solely in
Massachusetts. 

 (b) Purchaser understands the term “accredited investor” as used in Regulation D
promulgated under the Act and represents and warrants to the Company that he is an “accredited investor” for purposes of acquiring the Shares. The nature and amount of Purchaser’s investment in the Shares is consistent with
Purchaser’s investment objectives, abilities and resources. Purchaser understands that the Shares are an illiquid investment, which will not become freely transferable by reason of any “change of circumstances” whatever. Purchaser has
adequate means of providing for Purchaser’s current needs and possible contingencies and has no need for liquidity in Purchaser’s investment. 

(c) Purchaser is acquiring the Shares for Purchaser’s own account for investment, and not for, with a view to, or in connection with the
resale or distribution thereof. Purchaser has no present intention to sell, hypothecate, distribute or otherwise transfer the Shares or any portion thereof or any interest therein. 

(d) Purchaser understands that the Shares will constitute “restricted securities” within the meaning of Rule 144 promulgated under
the Act and that, as such, the Shares must be held indefinitely unless they are subsequently registered under the Act or unless an exemption from the registration requirements thereof is available. Purchaser has been advised that Rule 144, which
permits the resale, subject to various terms and conditions, of small amounts of such “restricted securities” after they have been held for six months, does not now apply to the Company, because the Company is not now required to file, and
does not file, current reports under the Securities Exchange Act of 1934, and because information concerning the Company substantially equivalent to that which would be available if the Company were required to file such reports is not now publicly
available. The Company may become a reporting entity at some future date, but no assurance can be given that it will do so. 
 (e) In
connection with Purchaser’s acquisition of the Shares, Purchaser accepts the condition that the Company may maintain “stop transfer” orders with respect to the Shares and that each certificate or other document evidencing the Shares
will bear conspicuous legends in substantially the form set forth in Section 5 of this Agreement. 
 (f) Purchaser has consulted
Purchaser’s attorney or accountant with respect to Purchaser’s purchase of the Shares. Purchaser has fully investigated the Company and its business and financial condition and has knowledge of the Company’s current activities.
Purchaser acknowledges that the Company has granted Purchaser and Purchaser’s attorney or accountant access to all information about the Company which they have requested and has offered each of them access to all further information which they
deemed relevant to an investment decision with respect to the Shares. Purchaser and Purchaser’s attorney or accountant have had the opportunity to ask questions of, and receive answers from, representatives of the Company concerning such
information and the Company’s financial condition and prospects. 

 4. Restrictions on Transfer. The following restrictions on transfer of the Shares shall
apply: 
 (a) Securities Laws. No Shares, nor any interest therein, may be sold, assigned, pledged or otherwise transferred at any
time or under any circumstances unless (i) the Shares proposed to be transferred have been registered under the Act and qualified under applicable state securities laws, or (ii) the Company has received, or agreed to waive, an opinion of
counsel acceptable to the Company to the effect that such transfer may be effected without registration under the Act or qualification under the securities laws of relevant states and the proposed transferee has made such representations and
agreements as the Company shall require to assure compliance with the Act and such laws. 
 (b) Right of First Refusal. 

(i) Offer of Sale; Notice of Proposed Sale or Transfer. In the event that at any time Purchaser desires to sell, assign or otherwise
transfer any Shares or any interest therein, he shall first deliver written notice of his desire to do so (the “Notice”) to the Company. The Notice must specify the number of Shares proposed to be transferred, the name of the person
or persons to whom he proposes to transfer such Shares, the price at which such Shares are intended to be transferred and all other terms of the transaction, which must be bona fide. 

(ii) Company’s Option to Purchase. The Company shall have an option to purchase all or any part of the Shares offered in the
Notice for the price and on the terms specified in such Notice. The Company must exercise such option by giving written notice to Purchaser no later than fifteen (15) business days after receipt of such Notice. 

(iii) Closing of Purchase by Company. In the event the Company duly exercises its option to purchase all or a portion of the Shares,
the closing of such purchase shall take place at the offices of the Company five days after the expiration of the fifteen-day period. 

(iv) Failure to Fully Exercise Options to Purchase. If within the applicable time period Purchaser does not receive notice of the
Company’s intention to purchase the offered Shares, the offer shall be deemed to have been rejected. In such event, Purchaser may transfer title to the offered Shares within ninety (90) days from the date of the Notice, but such transfer
shall be made only to the proposed transferee or transferees and at the proposed price and on such other terms as stated in such Notice. Shares that are so transferred shall remain subject to Sections 4 through 6, inclusive, of this Agreement, and
as a condition to any transfer Purchaser shall obtain a written agreement from the transferee by which the transferee agrees to be bound by Sections 4 through 6, inclusive, of this Agreement. 

(c) Permitted Transfers. Any portion or all of the Shares may, without compliance with the provisions of Section 4(b), be
transferred by Purchaser to a member of his immediate family or to a family partnership or family trust, or on Purchaser’s death may be transferred to Purchaser’s estate or to those entitled to a distribution of the Shares under the laws
of descent and distribution, provided that Shares that are so transferred shall remain subject to this Section 4 and as a condition to any transfer Purchaser shall obtain a written agreement from the transferee by which the transferee agrees to
be bound by this Section 4. 
 (d) Remedies. No sale, assignment, pledge or other transfer of Shares shall be effective or given
effect on the books of the Company unless all of the applicable provisions of this Section 4 have been duly complied with. If any transfer of Shares is made or attempted in 

 
violation of such restrictions, or if Shares are not offered to the Company as required hereby, the Company shall have the right to purchase such Shares from the purported owner thereof or his or
his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which it may have, the Company may enforce its rights by actions for specific performance (to the extent permitted by
law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and voting rights, until all applicable provisions hereof have been complied with. 

(e) Lock-Up. Purchaser agrees that for a period of up to 180 days from the effective date of any registration of securities of the
Company (upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities), he will not sell, make any short sale or loan of, grant any option for the purchase of, or otherwise dispose of any Shares
held by him without the prior written consent of the Company or such underwriters, as the case may be. 
 5. Legends. Each
certificate representing Shares shall prominently bear legends in substantially the following forms: 
 The securities represented by this
certificate have been acquired for investment and have not been registered under the Securities Act of 1933. Such securities may not be sold, transferred, pledged or hypothecated unless the registration provisions of said Act have been complied with
or unless the Corporation has received an opinion of counsel reasonably satisfactory to the Corporation that such registration is not required. 

The securities represented by this certificate have been acquired for investment and have not been registered or qualified under the securities
or “Blue Sky” laws of any jurisdiction. Such securities may not be sold, transferred, pledged or hypothecated unless the registration, qualification and filing requirements of all applicable jurisdictions have been satisfied or the
Corporation has received an opinion of counsel reasonably satisfactory to the Corporation that the proposed transaction will be exempt from registration, qualification, and filings in all such jurisdictions. 

The Corporation is authorized to issue more than one class of stock. The powers, designations, preferences and relative participating, optional
or other special rights, and the qualifications, limitations or restrictions of such preferences and/or rights of each class of stock or series of any class are set forth in the Certificate of Incorporation of the Corporation. The Corporation will
furnish a copy of the Certificate of Incorporation of the Corporation to the holder hereof without charge upon written request. 
 The
securities represented by this certificate are subject to restrictions on transfer pursuant to the terms of a Restricted Stock Purchase Agreement, as amended from time to time, between the owner of this certificate and the Corporation. The
Corporation will furnish a copy of this agreement to the holder hereof without charge upon written request. 
 6. Miscellaneous. 

(a) Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof, and
supersedes all prior agreements, negotiations, representations and proposals, written or oral, relating to such subject matter.

invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and all other provisions shall remain in full force and effect. If any of the provisions of

(f) Construction. A reference to a Section shall mean a Section of this Agreement unless otherwise expressly stated. The titles and
headings herein are for reference purposes only and shall not in any manner limit the construction of this Agreement which shall be considered as a whole. The words “include,” “includes” and

with the right to grant sublicenses, in the Territory under and to use Improvements to research, develop, make, have made, use, sell, offer for sale and import Licensed Products to the extent necessary to practice the license granted in
Section 2.1 above. LICENSOR further grants to LICENSEE an option to obtain an exclusive license with respect to any Improvement, which may be exercised by LICENSEE by providing LICENSOR with written notice within [**] months of disclosure of
such Improvement. Upon exercise of such option, such Improvement will be added to Licensed Intellectual Property under this Agreement. If LICENSEE fails to provide written notice within [**] months of disclosure of any Improvement, LICENSEE shall
have no further rights to such Improvement. 
 2.3 No Implied Licenses. Except as expressly set forth in this Agreement, neither
Party grants any licenses under its intellectual property rights to the other Party. 
 2.4 Retained Rights. LICENSOR retains the
right to practice the Licensed Intellectual Property for its internal research and educational purposes; provided, however, that LICENSOR may not practice the Licensed Intellectual Property in research conducted under funding from or in
collaboration with a commercial entity if such commercial entity will receive rights to, or an option to license, intellectual property arising from such sponsorship or collaboration; and LICENSOR agrees not to conduct any clinical studies or other
clinical activities during the Term requiring the practice of the Licensed Intellectual Property. 
 2.5 Sublicenses. LICENSEE may
grant sublicenses under the license granted pursuant to Section 2.1; provided, that: (a) all such sublicenses are consistent with and subject to the terms and conditions of this Agreement; (b) no sublicense shall relieve LICENSEE of
any of its obligations hereunder, and LICENSEE shall take all steps that may be reasonably necessary to enforce compliance by sublicensees with the terms and conditions of the respective sublicense agreement and shall further take all steps that may
be reasonably necessary to enforce that compliance to the extent required to allow LICENSEE to fully comply with all of its obligations under this Agreement; (c) each sublicense shall provide that the obligations of LICENSEE under Sections 3.3,
3.5, 3.6, 3.7, 5.3, 5.4, 7.2, 7.4 and Article 8 will be included in such sublicense; and (d) within [**] days of execution of an agreement by LICENSEE which includes a sublicense under any of LICENSEE’s rights under this Agreement,
LICENSEE will provide LICENSOR with a true and accurate copy of such sublicense agreement, including all exhibits, attachments, 

  
 7 

 
and all related documents, and any amendments thereto, which may be redacted with respect to obligations that are not relevant to this Agreement and which do not impose material obligations on
LICENSOR and which shall be Confidential Information of LICENSEE and subject to Article 8. 
 ARTICLE 3 

COMPENSATION 
 3.1
License Fees. LICENSEE shall pay to LICENSOR the following non-creditable, non-refundable license fees: 
 (i) a one-time upfront
license fee of [**] U.S. Dollars ($[**]); and 
 (ii) a fee of [**] U.S. Dollars ($[**]) upon issuance in the United States of a patent for
claims [**] as set forth in United States patent application [**], or issuance of a patent in the United States for claims substantially equivalent to the claims listed above. 

3.2 Milestone Payments. 

(a) Clinical and Sales Milestones. LICENSEE shall make milestone payments to LICENSOR based on achievement of milestone events achieved
by LICENSEE or its Affiliates or its Sublicensees for up to two (2) Licensed Products in accordance with the table below; provided, that, in order to be deemed to be a second Licensed Product eligible for the milestone payments for purposes of
this Section 3.2, such second Licensed Product must be comprised of a molecule that is distinct from the first Licensed Product and not a back-up or substitute for the first Licensed Product. LICENSEE shall notify LICENSOR in writing of the
achievement of each of the milestone events in the table below and pay to LICENSOR the amounts set forth below within [**] days of achievement of the relevant milestone event. Each milestone payment by LICENSEE to LICENSOR hereunder shall be payable
only once for a Licensed Product, regardless of the number of times achieved with respect to such Licensed Product. With respect to the Net Sales based milestone, payment shall be made only once regardless of the number of times annual worldwide Net
Sales for a Licensed Product reach the identified dollar threshold. Each milestone payment shall be nonrefundable and noncreditable against any other payments due under this Agreement.

be payable only once and solely with respect to the first and second Licensed Products, as applicable, in the Field of Use in the Territory to reach such milestone. 

(b) Business Milestones; Issuance of LICENSEE Common Stock. 

(i) Upon achievement of either of the following business milestone events by LICENSEE, LICENSEE shall (A) pay to LICENSOR the
corresponding cash milestone payments, and (B) issue to LICENSOR the corresponding number of shares of LICENSEE’s common stock, par value $0.001 per share (“LICENSEE Common Shares”) pursuant to the terms and subject to the
conditions set forth in a Stock Purchase Agreement to be executed by LICENSEE and LICENSOR (the “Stock Purchase Agreement”) substantially in the form to be negotiated by the Parties in good faith as soon as practicable after the
Effective Date:

	  	 	[**	] 	 	 	[**	] 

 (ii) Provisions Relating to LICENSEE Common Shares. The issuance of LICENSEE Common Shares to
LICENSOR upon achievement of the above business milestone events are subject to the following provisions: 
 (1) Adjustments. The
number of LICENSEE Common Shares issuable to LICENSOR shall be subject to adjustment for any stock dividends, stock splits, reverse stock splits, reclassifications, combinations, exchanges of shares, or other similar recapitalizations that are
implemented between the Effective Date and the date of achievement of the above milestones; provided, that, LICENSEE shall give LICENSOR prompt written notice of each such adjustment. 

(2) Compliance. The Stock Purchase Agreement shall include (A) a customary investor questionnaire whereby LICENSOR shall confirm
that it is an accredited investor and declare its suitability and holding intentions with respect to the LICENSEE Common Shares (which are consistent with applicable requirements for exemption of such issuance from registration requirements), and
provide any taxpayer identification or other information customarily required in similar private placements of securities and (B) 

  
 9 

 
representations of LICENSEE customary for investments in companies comparable to LICENSEE, which may be qualified by a disclosure schedule prepared by the LICENSEE immediately prior to the
execution of the Stock Purchase Agreement and issuance of LICENSEE Common Shares. 
 (3) Transfer and Other Restrictions. As a
further condition to each issuance of the LICENSEE Common Shares, LICENSOR shall execute all agreements reasonably requested by LICENSEE that are, at the time of each such issuance, similarly required of founders, key employees and/or certain other
common stockholders of LICENSEE, including but not limited to its Right of First Refusal and Co-Sale Agreement and Voting Agreement (which may provide, among other things, lock-up provisions upon an initial public offering, restrictions on transfer
of the LICENSEE Common Shares, requirements for voting LICENSEE Common Shares on certain matters and the affixing of certain legends on certificates evidencing LICENSEE Common Shares). Except as set forth in Section 10.6 regarding transfer to
Affiliates that explicitly assume all LICENSOR obligations, LICENSOR may not transfer its right to receive LICENSEE Common Shares upon achievement of the above business milestone events. 

(4) Sale of LICENSEE Prior to Issuance. If the closing of a LICENSEE Change of Control occurs prior to achieving the above business
milestone events and prior to issuance of any or all of the LICENSEE Common Shares to LICENSOR, then upon the achievement of any of such business milestone events, in lieu of LICENSEE (or the acquiror) issuing any LICENSEE Common Shares (or other
securities) to LICENSOR, LICENSEE shall pay LICENSOR a cash amount equal to the value of the consideration that LICENSOR would have received as a result of the LICENSEE Change of Control for such LICENSEE Common Shares otherwise issuable upon the
achievement of such business milestone event calculated as if all LICENSEE Common Shares potentially issuable pursuant to this Agreement were outstanding immediately prior to the LICENSEE Change of Control. For purposes of this
Section 3.2(b)(ii)(4), “LICENSEE Change of Control” shall mean a Liquidation Event or a Deemed Liquidation Event (as such terms are defined in LICENSEE’s certificate of incorporation). 

3.3 Royalties. 
 (a)
Rates. Subject to Sections 3.3(b), (c) and (d), LICENSEE shall pay royalties to LICENSOR based on Net Sales by LICENSEE, its Affiliates, and its Sublicensees in a given calendar year during the Royalty Term for such Licensed Product
according to the following rates: 
 (i) [**] percent ([**]%) for annual Net Sales less than or equal to $[**]. 

(ii) [**] percent ([**]%) for annual Net Sales greater than $[**]. 

(b) Royalty Term. “Royalty Term” means, on a country-by-country and Licensed Product-by-Licensed Product basis, the
period of time beginning upon the date of First Commercial Sale of a Licensed Product in that country, and ending upon the later of the expiration of the last-to-expire Valid Claim of a Licensed Patent claiming the composition, manufacture or use of
such Licensed Product. 

  
 10 

 (c) Royalty Adjustments for Third Party Payments. If LICENSEE or its Affiliates enter into
a license agreement with any Third Party under any Patent or other intellectual property right controlled by such Third Party that is necessary (as reasonably determined in good faith by LICENSEE) for the development, manufacture or
commercialization of a Licensed Product, and if LICENSEE or any of its Affiliates is required to pay to such Third Party a royalty, license fees, milestone or other payments, to obtain such license with respect to the development or
commercialization of Licensed Products, then the royalties due pursuant to clause (a) shall be reduced by [**] percent ([**]%) of the amount of all such payments reasonably attributable to such Licensed Product and paid to such Third Party;
provided, however, that the royalties payable to LICENSOR shall not be reduced in any such event to less than [**] percent ([**]%) of the amounts set forth in Section 3.3(a), solely by reason of any reduction under this Section 3.3(c). 

(d) Other Royalty Provisions. Only one royalty shall be due with respect to the same unit of Licensed Product. No royalties shall be
due upon the sale or other transfer among LICENSEE and its Related Parties, but in such cases the royalty shall be due and calculated upon LICENSEE’s or its Related Parties’ Net Sales to the first independent Third Party. No royalties
shall accrue on the sale or other disposition of the Licensed Product by LICENSEE or its Related Parties for use in a clinical study sponsored or funded by LICENSEE or on the disposition of a Licensed Product in reasonable quantities by LICENSEE or
its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose). 

3.4 Sublicense Income. LICENSEE shall pay LICENSOR sublicense fees in accordance with the following amounts as a percentage of
Sublicense Income received by LICENSEE: 
 (i) an amount equal to [**] percent ([**]%) of any Sublicense Income if the effective date of
the agreement in which a sublicense under LICENSEE’s rights in this Agreement is granted is on or before the [**] anniversary of the Effective Date; 

(ii) an amount equal to [**] percent ([**]%) of any Sublicense Income if the effective date of the agreement in which a sublicense under
LICENSEE’s rights in this Agreement is granted is on or before the [**] anniversary of the Effective Date; or 
 (iii) an amount equal
to [**] percent ([**]%) of any Sublicense Income if the effective date of the agreement in which a sublicense under LICENSEE’s rights in this Agreement is granted is after the [**] anniversary of the Effective Date. 

3.5 Royalty Payment and Reports. Within [**] days after the end of each calendar quarter after the First Commercial Sale of a Licensed
Product, LICENSEE shall deliver to LICENSOR a report containing the following information for the prior calendar quarter: 
 (a) the
gross sales associated with each Licensed Product sold by LICENSEE and its Related Parties; 

  
 11 

 (b) a calculation of Net Sales of each Licensed Product that is sold by LICENSEE and its
Related Parties; 
 (c) the amount of Sublicense Income received by LICENSEE from its Sublicensees with respect to each Licensed
Product; 
 (d) the amount of taxes, if any, withheld to comply with applicable law; and 

(e) a calculation of payments due to LICENSOR with respect to the foregoing (including without limitation the calculation of any
deductions from Net Sales pursuant to section 1.29 and royalty adjustments pursuant to Section 3.3 and any calculation of currency conversion). 

Concurrent with these reports, LICENSEE shall remit to LICENSOR any payment due for the applicable calendar quarter. All such reports shall be considered
Confidential Information of LICENSEE and shall be maintained in confidence by LICENSOR pursuant to Article 8. If no royalties or other payments are due to LICENSOR for such reporting period, the report shall so state. Along with the last report for
a calendar year provided hereunder, LICENSOR shall provide a final report for the entire such year, and a statement on whether any reconciling payments must be made at such time to effect the intent of this Article 3. Within [**] days after such
statement is provided, the Party that owes any amounts to the other Party to effect such reconciliation shall pay the relevant amount to the other Party. 

3.6 Tax Withholding. If LICENSEE concludes that tax withholdings under the laws of any country within the Territory are required with
respect to payments to LICENSOR, LICENSEE shall withhold the required amount and pay it to the appropriate governmental authority. In any such case, LICENSEE shall promptly provide LICENSOR with original receipts or other evidence reasonably
desirable and sufficient to allow LICENSOR to document such tax withholdings for purposes of claiming foreign tax credits and similar benefits. 

3.7 Currency; Blocked Payments. All dollar ($) amounts specified in this Agreement are United States dollar amounts and all
payments to be made under this Agreement shall be made in United States dollars and shall be paid by bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by the LICENSOR from
time to time. In the case of sales of Licensed Products outside the United States by LICENSEE and its Related Parties, the rate of exchange to be used in computing the amount of currency equivalent in United States dollars due shall be made at the
conversion rate existing in the United States (as reported in The Wall Street Journal) on the last business day of the quarter immediately preceding the applicable calendar quarter. If The Wall Street Journal ceases to be published,
then the rate of exchange to be used shall be that reported in such other business publication of national circulation in the United States as the Parties reasonably agree. In the event that, by reason of applicable laws or regulations in any
country, it becomes illegal for LICENSEE to transfer, or have transferred on its behalf, royalties or other payments to LICENSOR, payments shall be made in the country in local currency by deposit in a local bank designated by the LICENSOR. 

  
 12 

 3.8 Records and Audits. LICENSEE shall keep, and shall require all its Related Parties to
keep, correct and complete books of accounts and other records containing all information and data which may be necessary to ascertain and verify the royalties payable under this Agreement. During the Term and for a period of [**] years following
its termination, LICENSOR shall have the right from time to time (not to exceed [**]) to have an independent certified public accountant inspect such books and records of LICENSEE and/or its Affiliates at LICENSOR’s expense. Such inspection
shall be conducted after reasonable prior notice by LICENSOR to LICENSEE during LICENSEE’s ordinary business hours, shall not be more frequent than [**] and may cover only the [**] years immediately preceding the date of the audit. Any such
independent certified accountant shall be reasonably acceptable to LICENSEE and, if reasonably requested by LICENSEE, shall execute LICENSEE’s standard form of confidentiality agreement, and shall be permitted to share with LICENSOR solely its
findings with respect to the accuracy of the royalties reported as payable under this Agreement. If such accounting determines that LICENSEE paid LICENSOR less than the amount properly due in respect of any calendar quarter, then LICENSEE will
reimburse LICENSOR such amount, and if the amount underpaid exceeds [**] percent ([**]%) of the amount actually due, LICENSEE will also reimburse LICENSOR for the costs of such accounting (including the fees and expenses of the certified public
accountant). In the event such accounting determines that LICENSEE paid LICENSOR more than the amount properly due in respect of any calendar quarter, then any excess payments made by LICENSEE shall be credited against future amounts due to LICENSOR
from LICENSEE, or if no such future amounts are reasonably expected to be due to LICENSOR from LICENSEE, then LICENSOR shall reimburse LICENSEE for any overpayment by LICENSEE. 

3.9 Adjustments for MEEI License Grant. If at any time during the Term, LICENSOR and The Massachusetts Eye and Ear Infirmary, a
Massachusetts nonprofit corporation having a place of business at 243 Charles Street, Boston, Massachusetts 02114 (“MEEI”), enter into an agreement pursuant to which LICENSOR acknowledges that MEEI has an ownership interest in the
Licensed Patents, or it is otherwise determined by a court of competent jurisdiction that MEEI has an ownership interest in the Licensed Patents, and, in either such case, LICENSEE does not, in a timely manner, become exclusively licensed under
MEEI’s interest in the Licensed Patents pursuant to a written amendment to this Agreement, (i) LICENSOR shall provide LICENSEE with prompt written notice as soon as it becomes aware of such occurrence and (ii) LICENSEE and
LICENSOR shall, as promptly as possible thereafter, enter into good faith negotiations with respect to an amendment to this Agreement providing for a reasonable reduction to the compensation terms set forth in this Article 3 to account for the
circumstance of LICENSEE not being exclusively licensed under this Agreement with respect to the interests of all owners of the Licensed Patents, and specifically taking into account any amount that is or may be due from LICENSEE as consideration to
obtain an exclusive right under MEEI’s interest in the Licensed Patents. The Parties shall negotiate the amendment in good faith and with sufficient diligence as is necessary to execute and deliver the amendment within [**] days of the issuance
by LICENSOR of the notice described above. 
 Until such time, if any, that MEEI withdraws its allegation as to ownership of the Licensed Patents or the
allegation is otherwise resolved by LICENSEE and MEEI, LICENSOR agrees to provide interim written updates to LICENSEE (no less than [**]) on the status of LICENSOR’s interactions with MEEI and/or resolution with respect to this matter.

 ARTICLE 4 

TECHNOLOGY TRANSFER; REGULATORY MATTERS; DILIGENCE 

4.1 Technology Transfer. 

(a) LICENSOR shall, as soon as possible after the Effective Date, provide LICENSEE with all Licensed Know-How (including without
limitation source-verified case report forms and all other clinical trial data pertaining to studies involving Licensed Intellectual Property) in its Control that are necessary or useful for the exploitation of the Licensed Intellectual Property
and/or the research, development, manufacture, Regulatory Approval or commercialization of Licensed Products. LICENSOR acknowledges that data and information derived in, or generated from, the conduct of the clinical study entitled “Safety and
Efficacy of Topical Interleukin-1 Receptor Antagonist in the Treatment of Signs and Symptoms of Posterior Blepharitis” conducted at the Massachusetts Eye and Ear Infirmary under an IND (Ref. No. 101,168) is reasonably believed by LICENSEE
to be of crucial importance for LICENSEE’s ability to carry out its responsibilities and obligations under this Agreement. Accordingly, in the event LICENSEE is not able to secure the data and information described in the foregoing sentence
from the sponsor of the study within [**] months of the Effective Date, LICENSOR agrees to negotiate in good faith with respect to any request by LICENSEE to adjust performance deadlines or diligence requirements under this Agreement. 

(b) The materials transferred to LICENSEE by LICENSOR hereunder are transferred on an “as is” basis, subject only to
LICENSOR’s representations and warranties under this Agreement. 
 4.2 Regulatory Matters. LICENSEE (or its Related Parties)
shall file and own all INDs, marketing authorization applications and Regulatory Approvals for Licensed Products, and any related items such as investigator’s brochures or IRB approvals, in the Field and in the Territory (collectively,
“Regulatory Filings”), and shall be solely responsible for all communications with Regulatory Authorities in relation thereto. LICENSOR agrees that LICENSEE will have the right to access all results from and to reference all
regulatory filings and data obtained in current or completed clinical trials conducted by LICENSOR involving Kineret® with [**] as principal investigator or any successor principal
investigator for such clinical trials. LICENSOR will cooperate with, and provide reasonable assistance to LICENSEE or its Related Parties, in the preparation and submission of any portions of any Regulatory Filings that rely upon or contain
information or data in the Licensed Intellectual Property generated by or on behalf of LICENSOR. 
 4.3 Diligence. LICENSEE shall use
Commercially Reasonable Efforts to research, develop and commercialize a Licensed Product in the Field in the Territory. For purposes of this Section 4.3, the efforts of LICENSEE’s Related Parties shall also be considered the efforts of
LICENSEE. LICENSEE will be deemed to have demonstrated Commercially Reasonable Efforts if, within [**] years of the Effective Date, LICENSEE has (a) achieved the Additional License Agreements Milestone or (b) established a scientific
program, including a research plan and budget, with respect to a protein-based interleukin-1 antagonist program. Within [**] months of the first to occur of the achievement by LICENSEE of either (a) or (b) above and the [**] anniversary of
the Effective Date, the Parties will negotiate in good faith and agree upon a 

  
 14 

 
set of diligence milestones to be achieved by LICENSEE with respect to the development and commercialization of Licensed Products, which will be included in writing as an Appendix to this
Agreement. In the event LICENSEE determines that it is unable to meet, or otherwise fails to meet, a diligence milestone, LICENSEE will notify LICENSOR in writing and provide an explanation of the reasons that the diligence milestone has not or will
not be met. The Parties will promptly negotiate in good faith an amendment to the diligence milestone which may include a reasonable extension of the time required to achieve the milestone based on the circumstances and LICENSEE’s explanation
and an obligation of LICENSEE to provide periodic status reports to LICENSOR with respect to its efforts to develop and commercialize Licensed Products, which amendment will be included as an update to the relevant Appendix to this Agreement. 

ARTICLE 5 
 INTELLECTUAL
PROPERTY 
 5.1 Ownership of Inventions. Each Party shall own all Know-How developed and inventions conceived or reduced to
practice solely by its employees, agents or independent contractors (each, a “Sole Invention”). Although the Parties do not intend or expect to jointly develop any know-how or inventions, in the event they do so, then all inventions
made jointly by employees, agents or independent contractors of each Party shall be owned jointly by the Parties such that each Party has an undivided one-half interest therein (“Joint Inventions”). (All Patents claiming patentable
Joint Inventions shall be referred to as “Joint Patents.”) Except to the extent either Party is restricted by the rights granted to the other Party and covenants contained herein, each Party shall be entitled to practice, and to
grant to Third Parties or its Related Parties the right to practice, inventions claimed in a Joint Patent without restriction or an obligation to account to the other Party. Inventorship shall be determined in accordance with United States patent
laws. 
 5.2 Prosecution of Patents. 

(a) Licensed Patents. LICENSOR shall have the right, but not the obligation, at its expense, to obtain, prosecute, maintain and defend
throughout the Territory the Licensed Patents. In this regard, LICENSOR shall use commercially reasonable efforts to file, prosecute, maintain and defend patent applications to secure claims of the Licensed Patents. LICENSOR will instruct patent
counsel to copy LICENSEE on all material filings and correspondence with respect to Licensed Patents and to provide for reasonable participation by LICENSEE in all material dealings with patent counsel and patent offices with respect to Licensed
Patents. LICENSOR shall consider and incorporate all reasonable comments of LICENSEE with respect to patent filing and correspondence with patent offices unless determined to be materially detrimental to LICENSOR’s rights in Licensed Patents.
If LICENSOR elects not to (i) pursue the filing, prosecution, maintenance or defense of a Licensed Patent or any claim therein in a particular country, or (ii) take any other action with respect to a Licensed Patent in a particular country
that is necessary or useful to establish or preserve rights thereto, then in each such case LICENSOR shall so notify LICENSEE promptly in writing and in reasonable time to enable LICENSEE to meet any deadlines by which an action must be taken to
establish or preserve any such rights in such Licensed Patent, as applicable, in such country. Upon receipt of each such notice by LICENSOR or if, at any time, LICENSOR fails to initiate any such action after a

  
 15 

 
request by LICENSEE that it do so, LICENSEE shall have the right, but not the obligation, to pursue the filing or support the continued prosecution, maintenance or defense of such Licensed Patent
at its expense in such country. If LICENSEE elects to pursue such filing or continue such support, then LICENSEE shall notify LICENSOR of such election. Each Party shall, at the other Party’s request, assist and cooperate in the filing and
prosecution, maintenance or defense of any application, amendment, submission, response or correspondence with respect to any Licensed Patents. Each Party shall provide the other Party, sufficiently in advance for the other Party to comment, with
copies of all patent applications and other material submissions and correspondence with any patent counsel or patent authorities pertaining to the Licensed Patents. Each Party shall give due consideration to the comments of the other Party. 

(b) Other Patents Claiming Inventions. Subject to Section 5.2(a), each Party shall be responsible, at its expense, for the
prosecution and maintenance of Patents claiming its Sole Inventions. The Parties shall mutually agree upon which Party shall prosecute Joint Patents that are not Licensed Patents, based on the contribution of each Party to such invention and each
Party’s potential interest in products based upon such invention. If either Party prosecutes a Joint Patent pursuant to this Section 5.2(b), such Party shall solely bear its own internal costs for such prosecution, and the external costs
for such prosecution (e.g., outside counsel, filing fees, etc.) shall be borne equally by the Parties unless otherwise mutually agreed. 

(c) Audit. LICENSOR will keep complete and accurate copies of all invoices and statements it receives from its patent counsel with
respect to patent expenses to be reimbursed by LICENSEE under Section 5.2(d). 
 (d) Patent Expenses. Beginning on the Effective
Date, LICENSEE will reimburse LICENSOR for all reasonable out-of-pocket expenses for patent prosecution incurred after the Effective Date; provided, that, if requested in writing by LICENSOR, LICENSEE shall pay such expenses directly to
LICENSOR’s patent counsel. With respect to reasonable out-of-pocket patent expenses incurred prior to the Effective Date, LICENSOR will be responsible for [**] U.S. dollars ($[**]) of those patent expenses incurred after [**] through the
Effective Date and LICENSEE will be responsible for out-of-pocket patent expenses that exceed [**] U.S. dollars ($[**]) during such time period. 

5.3 Infringement of Certain Patents by Third Parties. Each Party shall promptly notify the other Party in writing of any alleged or
threatened infringement of the Licensed Patents of which it becomes aware. 
 (a) Licensed Patents. LICENSEE shall have the first
right, but not the obligation, to initiate an appropriate suit anywhere in the world against any Third Party who at any time is suspected of infringing all or any portion of the Licensed Patents or using without proper authorization all or any
portion of the Licensed Know-How (each an “Infringement”) within the Field and within the Territory, and shall control any such action for which it exercises such right. LICENSEE shall notify LICENSOR in writing of its initiation of
an Infringement action. LICENSOR shall have the right to participate in such action and to be represented in such action by counsel of its own choice, at LICENSOR’s expense. If LICENSEE fails to institute and prosecute an action or proceeding
to abate the Infringement within a period of [**] days after receiving written notice or otherwise having Knowledge of the Infringement, then 

  
 16 

 
LICENSOR shall have the right, but not the obligation, to bring and prosecute any such action; provided, however, that in such event the LICENSOR shall have the right to participate in
such action and to be represented in any such action by counsel of its choice. If necessary, in any action brought pursuant to this Section 5.3, the Party not controlling such action agrees to be joined as a party plaintiff and to give
reasonable assistance and any needed authority to control, file and to prosecute such action. Neither Party may enter into any settlement under this Section 5.3(a) that affects adversely the other Party’s rights or interests without such
other Party’s written consent, which consent shall not be unreasonably withheld. If the Parties obtain any damages, license fees, royalties or other compensation (including any amount received in settlement of such litigation) from a Third
Party in connection with a suit relating to the Infringement, such amounts shall be allocated as follows: 
 (i) first, in all cases, to
reimburse each Party for all reasonable expenses of the suit, including reasonable attorneys’ fees and disbursements, court costs and other litigation expenses; 

(ii) second, to LICENSEE for any amounts recovered for lost sales of Licensed Product as if it were Net Sales of LICENSEE, with LICENSOR
receiving a royalty on such remaining amount pursuant to the terms of Section 3.3 (after adding such amount to aggregate Net Sales for purposes of determining the applicable royalty rate), and the balance being retained by LICENSEE; and 

(iii) third, any amounts remaining shall be allocated as follows: (A) if LICENSOR is the Party bringing such suit or proceeding or
taking such other legal action, [**] percent ([**]%) to LICENSOR, and [**] percent ([**]%) to LICENSEE; (B) if LICENSEE is the Party bringing such suit or proceeding or taking such other legal action, [**] percent ([**]%) to LICENSEE, and [**]
percent ([**]%) to LICENSOR, and (C) if the suit is brought jointly, [**] percent ([**]%) to each Party. 
 (b) Joint Patents.
The Parties shall each have the right, but not the obligation to prosecute infringement of any Joint Patents that are not Licensed Patents; provided, that, they first confer and mutually agree regarding such matter. 

5.4 Infringement of Third Party Rights. If any Licensed Product that is manufactured, used or sold by or for LICENSEE becomes the
subject of a Third Party’s claim or assertion of infringement of a Patent controlled by such Third Party, the Party first having notice of the claim or assertion shall promptly notify the other Party in writing, and the Parties shall promptly
meet to consider the claim or assertion and the appropriate course of action. Each Party shall have the right to take action to defend any such claim brought against it by a Third Party, provided, however, that neither Party shall enter into any
settlement of any claim described in this Section 5.4 that affects adversely the other Party’s rights or interests without first obtaining such Party’s written consent, which consent shall not be unreasonably withheld. Nothing in this
Section 5.4 shall be deemed to relieve either Party of its obligations under Article 7. 
 5.5 Other Infringement
Resolutions. In the event of a dispute or potential dispute which has not ripened into a demand, claim or suit of the types described in Sections 5.3 and 5.4, the same principles governing control of the resolution of the dispute, consent to
settlement of the dispute, and implementation of the settlement of the dispute (including the sharing in and allocating the payment or receipt of damages, license fees, royalties and other compensation) shall apply. 

  
 17 

 5.6 Patent Marking. Each Party agrees to comply with the patent marking statutes in each
country in which a Licensed Product is sold by such Party or its Related Parties. 
 ARTICLE 6 

REPRESENTATIONS, WARRANTIES AND COVENANTS 

6.1 Mutual Representations and Warranties. Each Party hereby represents, warrants and covenants to the other Party as of the Effective

THAT THE DEVELOPMENT, MANUFACTURE OR COMMERCIALIZATION OF ANY LICENSED PRODUCT PURSUANT TO THIS AGREEMENT WILL BE SUCCESSFUL OR THAT ANY PARTICULAR SALES LEVEL WITH RESPECT TO A LICENSED PRODUCT WILL BE ACHIEVED. 

ARTICLE 7 

INDEMNIFICATION AND INSURANCE 

7.1 Indemnification by LICENSEE. LICENSEE hereby agrees to Indemnify LICENSOR and its Affiliates and their respective agents,
directors, officers and employees (the “LICENSOR Indemnitees”) from and against any and all liabilities, expenses and/or losses (collectively, “Losses”) resulting from Third Party suits, claims, actions and demands to the
extent arising from or related to (a) a breach of any representation, warranty, covenant or other obligation of LICENSEE set forth in this Agreement, or (b) the research, development, manufacture, commercialization, supply, promotion, sale
or use by any person of Licensed Products developed or commercialized by LICENSEE, its Related Parties or any Sublicensee, except to the extent a Loss arises from the gross negligence or willful misconduct of a LICENSOR Indemnitee as defined above
in this Section 7.1. 
 7.2 Procedure. To be eligible to be indemnified hereunder, the indemnified Party shall provide the
indemnifying Party with prompt notice of the claim giving rise to the indemnification obligation pursuant to this Article 7 and the exclusive ability to defend (with the reasonable cooperation of the indemnified Party) or settle any such claim;
provided, however, that the indemnifying Party shall not enter into any settlement for damages other than monetary damages without the indemnified Party’s written consent, such consent not to be unreasonably withheld. The indemnified Party
shall have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the indemnifying Party. If the Parties cannot agree as to the application of Section 7.1 to any
particular Third Party Claim, the Parties may conduct separate defenses of such Third Party Claim. Each Party reserves the right to claim indemnity from the other in accordance with Section 7.1 above upon resolution of the underlying claim,
notwithstanding the provisions of this Section 7.2 requiring the indemnified Party to tender to the indemnifying Party the exclusive ability to defend such claim or suit. 

7.3 Limitation of Liability. NEITHER PARTY WILL BE LIABLE UNDER ANY LEGAL THEORY (WHETHER TORT, CONTRACT OR OTHERWISE) FOR SPECIAL,
INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH
DAMAGES. NOTHING IN THIS SECTION 7.3 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY. 

  
 20 

 7.4 Insurance. LICENSEE shall maintain insurance during the Term of this Agreement and for
a period of at least [**] years thereafter with a reputable, solvent insurer in an amount appropriate for its business and products of the type that are the subject of this Agreement, and for its obligations under this Agreement. LICENSEE shall
provide the LICENSOR with evidence of the existence and maintenance of such insurance coverage upon LICENSEE’s prior written request. 

ARTICLE 8 

CONFIDENTIALITY AND PUBLICITY 

8.1 Confidential Information. Each Party agrees (a) to take all steps reasonably necessary to maintain the confidentiality of the
Confidential Information of the other Party, (b) not to disclose the other Party’s Confidential Information to any Third Party without the prior written consent of such other Party, and (c) to use such Confidential Information only as
necessary to fulfill its obligations or in the reasonable exercise of rights granted to it under this Agreement; provided, however, that the foregoing obligations shall not apply to Confidential Information that (i) is in possession of the
receiving Party at the time of disclosure, as reasonably demonstrated by written records and without obligation of confidentiality, (ii) later becomes part of the public domain through no fault of the receiving Party, (iii) is received by
the receiving Party without obligation of confidentiality from a Third Party with a right to such information, or (iv) is developed independently by the receiving Party without use of, reference to, or reliance upon the disclosing Party’s
Confidential Information by individuals who did not have access to such Confidential Information. Furthermore, a Party may disclose Confidential Information of the other Party to (x) its Affiliates, and to its and their directors, employees,
consultants, and agents in each case who have a specific need to know such Confidential Information and who are bound by a like obligation of confidentiality and restriction on use, (y) any bona fide actual or prospective collaborators,
underwriters, investors, lenders or other financing sources who are obligated to keep such information confidential, to the extent reasonably necessary to enable such actual or prospective collaborators, underwriters, investors, lenders or other
financing sources to determine their interest in collaborating with, underwriting or making an investment in, or otherwise providing financing to, the receiving Party, and (z) the extent such disclosure is required to comply with applicable law
or regulation or the order of a court of competent jurisdiction, to defend or prosecute litigation or to comply with the rules of the U.S. Securities and Exchange Commission, any stock exchange or listing entity; provided, however, that the
receiving Party provides prior written notice of such disclosure to the disclosing Party and takes reasonable and lawful actions to avoid or minimize the degree of such disclosure. Notwithstanding any other provision of this Agreement, each Party
may disclose and use Confidential Information of the other Party as necessary to file or prosecute patent applications, prosecute or defend litigation or otherwise establish rights or enforce obligations under this Agreement, or to submit Regulatory
Filings. Moreover, LICENSEE may disclose Confidential Information of LICENSOR relating to the research, development or commercialization of Licensed Products to entities with whom LICENSEE has (or may have) a marketing and/or development
collaboration and who have a specific need to know such Confidential Information and who are bound by a like obligation of confidentiality and restrictions on use. 

  
 21 

 8.2 Publicity. Subject to the written consent of LICENSEE (which shall not be unreasonably
withheld or delayed), LICENSEE shall have the right, but not the obligation, to issue a mutually agreed press release regarding the subject matter of this Agreement. Each Party understands that this Agreement is likely to be of significant interest
to investors, analysts and others and, therefore, that either Party shall have the right to make announcements of events or developments with respect to this Agreement that are material to such Party; provided, that, such announcement shall be
subject to the prior consent of the other Party, which shall not be unreasonably withheld or delayed. The Parties agree that any such announcement shall not contain Confidential Information or, if disclosure of Confidential Information is required
by law or regulation or the rules of or the rules of the U.S. Securities and Exchange Commission, any stock exchange or listing entity, shall make reasonable efforts to minimize such disclosure and obtain confidential treatment for any such
information that is disclosed to a government agency. Each Party agrees to provide the other Party with a copy of any public announcement as soon as reasonably practicable prior to its scheduled release. Except in the case of extraordinary
circumstances, each Party shall provide the other with an advance copy of any announcement at least [**] days prior to its scheduled release. Each Party shall have the right to expeditiously review and recommend changes to any announcement regarding
this Agreement, provided that such right of review and recommendation shall only apply for the first time that specific information is disclosed and shall not apply to the subsequent disclosure of substantially similar information that has been
previously disclosed. Notwithstanding the foregoing, LICENSEE may, without the prior consent of LICENSOR, disclose the existence of this Agreement and its terms to Third Parties with whom LICENSOR has or is contemplating a business relationship who
have a specific need to know such Confidential Information in connection with such proposed relationship and who are bound by a like obligation of confidentiality and restrictions on use; provided, however, that any press release is subject to
mutual consent as provided above. 
 ARTICLE 9 

TERM AND TERMINATION 

9.1 Term. This Agreement shall become effective on the Effective Date and unless earlier terminated pursuant to this Article 9, shall
remain in effect until the expiration of the last-to-expire Royalty Term for all Licensed Products (the “Term”). Thereafter, the rights granted under Article 2 shall become non-exclusive, fully-paid and perpetual. 

9.2 Elective Termination. LICENSEE shall have, at any time, the right to terminate this Agreement at will in its entirety upon sixty
(60) days prior written notice to LICENSOR. 
 9.3 Termination for Breach. If either Party believes that the other is in
material breach of this Agreement, then the Party holding such belief (the “Non-Breaching Party”) may deliver notice of such breach to the other Party (the “Notified Party”). The Notified Party shall have
(a) [**] days to cure such breach to the extent involving non-payment of amounts due under this Agreement, and (b) [**] days to either cure such breach for all other material breaches, or, if cure of such breach other than non-payment
cannot reasonably be effected within such [**] day period, to deliver to the Non-Breaching Party a plan reasonably calculated to cure such breach within a timeframe that is reasonably prompt in light of the circumstances then prevailing, which shall
not exceed [**] days. Following delivery of such a plan, the Notified Party shall carry out the plan and cure the breach. If the Notified Party fails to cure a material breach of this 

  
 22 

 
Agreement as provided above, then the Non-Breaching Party may terminate this Agreement upon written notice to the Notified Party. If there is a good faith dispute as to the existence or cure of a
breach or default pursuant to this Section 9.3, all applicable cure periods will be tolled during the existence of such good faith dispute and no termination for a breach which is disputed in good faith shall become effective until such dispute
is resolved. 
 9.4 Termination for Bankruptcy. 

(a) This Agreement may be terminated by either Party upon the filing or institution of bankruptcy, reorganization, liquidation or
receivership proceedings, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, however, that in the event of any involuntary bankruptcy or receivership proceeding such right to
terminate shall only become effective if the Party consents to the involuntary bankruptcy or receivership or such proceeding is not dismissed within sixty (60) days after the filing of such bankruptcy or receivership. 

(b) If this Agreement is terminated by LICENSEE (the “Non-Bankrupt Party”) pursuant to Section 9.4(a) due to the
rejection of this Agreement by or on behalf of LICENSOR (the “Bankrupt Party”) under Section 365 of the United States Bankruptcy Code (the “Bankruptcy Code”), all licenses and rights to licenses granted under
or pursuant to this Agreement by the Bankrupt Party to the Non-Bankrupt Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined
under Section 101(35A) of the Bankruptcy Code. The Parties agree that the Non-Bankrupt Party, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code, and
that upon commencement of a bankruptcy proceeding by or against the Bankrupt Party under the Bankruptcy Code, the Non-Bankrupt Party shall be entitled to a complete duplicate of, or complete access to (as the Non-Bankrupt Party deems appropriate),
any such intellectual property and all embodiments of such intellectual property. Such intellectual property and all embodiments thereof shall be promptly delivered to the Non-Bankrupt Party (i) upon any such commencement of a bankruptcy
proceeding upon written request therefor by the Non-Bankrupt Party, unless the Bankrupt Party elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this
Agreement by or on behalf of the Bankrupt Party upon written request therefor by the Non-Bankrupt Party. The foregoing provisions are without prejudice to any rights the Non-Bankrupt Party may have arising under the Bankruptcy Code or other
applicable law. 
 9.5 Consequences of Termination. 

(a) If the Agreement is terminated for any reason other than by LICENSEE pursuant to Section 9.3, all licenses and rights granted
by LICENSOR to LICENSEE under this Agreement shall immediately terminate. 
 (b) If LICENSEE terminates this Agreement pursuant to
Section 9.3, then all the rights transferred to it in Article 2 with respect to Licensed Products shall survive such termination until the Term would otherwise expire under Section 9.1; provided, that, LICENSEE continues to use
Commercially Reasonable Efforts to develop and commercialize all such Licensed Products and pay all amounts due to LICENSOR pursuant to Article 3 during the Royalty Term that would otherwise be applicable to such Licensed Products. 

  
 23 

 (c) In the event that the license granted to LICENSEE under this Agreement is terminated,
any granted sublicenses shall remain in full force and effect; provided, that, (i) the Sublicensee is not then in breach of its sublicense agreement and the Sublicensee agrees to be bound to LICENSOR as a licensee under the terms and conditions
of the sublicense agreement and (ii) the Sublicensee agrees to enter into appropriate agreements or amendments to the sublicense agreement to substitute itself for LICENSEE as the licensor thereunder. 

9.6 Survival. The following provisions shall survive any expiration or termination of this Agreement for the period of time specified
therein, or if not specified, then they shall survive indefinitely: Articles 1, 7 (solely as to actions arising during the Term or in the course of a Party’s exercise of licenses it retains after the Term), and 10, and Sections 3.5 (final
royalty report), 3.6, 3.7, 4.2, 5.1, 5.2(a) (if termination under Section 9.4 by LICENSEE), 5.2(b), 5.3 (if termination under Section 9.4 by LICENSEE), 5.4, 5.5, 6.3, 8.1, 9.4(b), 9.5, and 9.6. Termination of this Agreement shall not
relieve the Parties of any liability which accrued hereunder prior to the effective date of such termination nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of
this Agreement. Except as expressly set forth in Section 9.3, the remedies provided in this Article 9 are not exclusive of any other remedies a Party may have in law or equity.

 10.5 No Strict Construction. This Agreement has been prepared jointly and shall not be strictly
construed against either Party. 
 10.6 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations
hereunder without the prior written consent of the other Party, except that, subject to Section 10.7, a Party may make such an assignment or transfer without the other Party’s consent (a) to the assigning Party’s Affiliates or
(b) to the successor to all or substantially all of the business or assets of such Party to which this Agreement relates (whether by merger, sale of stock, sale of assets or other transaction). Any permitted successor or assignee of rights
and/or 

  
 25 

 
obligations hereunder shall, in a writing to the other Party, expressly assume performance of such rights and/or obligations, but the assigning Party will remain primarily liable and responsible
for the performance of all of its obligations under this Agreement and for causing its assignees to act in a manner consistent herewith. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted
assignment by either Party in violation of the terms of this Section 10.6 shall be null and void.

Affiliates. Each of LICENSOR and LICENSEE acknowledge that their obligations under this Agreement may be performed by their respective Affiliates. Notwithstanding any delegation of obligations under this Agreement by a Party to an Affiliate,
each Party shall remain primarily liable and responsible for the performance of all of its obligations under this Agreement and for causing its Affiliates to act in a manner consistent herewith. Wherever in this Agreement the Parties delegate
responsibility to Affiliates or local operating entities, the Parties agree that such entities shall not make decisions inconsistent with this Agreement, amend the terms of this Agreement or act contrary to its terms in any way. 

10.8 Independent Contractors. It is understood and agreed that the relationship between the Parties is that of independent contractors
and that nothing in this Agreement shall be construed as authorization for either Party to act as the agent for the other Party. 
 10.9
Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, 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. 

10.10 Severability. Each provision in this Agreement is independent and severable from the others, and no provision will be rendered
unenforceable because any other provision may be invalid or unenforceable in whole or in part. If the scope of any restrictive provision in this Agreement is too broad to permit enforcement to its full extent, then such restriction will be reformed
to the maximum extent permitted by law. 
 10.11 Headings. The headings for each Article and Section in this Agreement have been
inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. 

10.12 No Waiver. Any delay in enforcing a Party’s rights under this Agreement, or any waiver as to a particular default or other
matter, shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of
time. 
 10.13 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one (1) and the same instrument.
