 EXHIBIT 4.1 

FIFTH SUPPLEMENTAL INDENTURE 

FIFTH SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of November 8, 2016, among Century Communities,
Inc., a Delaware corporation (the “Company”), those companies listed in the Schedule to this Supplemental Indenture (the “Guaranteeing Subsidiaries”), each a subsidiary of the Company, the other Guarantors
(as defined in the Indenture referred to herein), and U.S. Bank National Association, as trustee under the Indenture (the “Trustee”). 

WITNESSETH 
 WHEREAS, the
Company has heretofore executed and delivered to the Trustee an indenture, dated as of May 5, 2014 providing for the issuance of 6.875% Senior Notes due 2022 (the “Securities”), as supplemented by the Supplemental Indenture
dated as of December 18, 2014, the Second Supplemental Indenture, dated as of March 13, 2015, the Third Supplemental Indenture, dated as of April 9, 2015, and the Fourth Supplemental Indenture, dated as of August 27, 2015 (as
supplemented, the “Indenture”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing
Subsidiaries shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiaries shall each unconditionally guarantee all of the Company’s Obligations under the Securities and the Indenture on the
terms and conditions set forth herein (each a “Security Guarantee”); and 
 WHEREAS, pursuant to Section 9.01
of the Indenture, the Company and the Trustee are authorized to execute and deliver this Supplemental Indenture without the consent of the Holders. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged,
the Company, the other Guarantors, the Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the equal and ratable benefit of the Securityholders as follows: 

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiaries each hereby agree to provide an unconditional Security Guarantee on the terms and
subject to the conditions set forth in the Security Guarantee and in the Indenture including but not limited to Article 10 thereof. 

3. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company or any Security Guarantor, as such,
will have any liability for any obligations of the Company or the Security Guarantors under the Securities, this Indenture, the Security Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Securityholder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities and the Security Guarantees. The waiver may not be effective to waive liabilities
under the federal securities laws. 
 4. GOVERNING LAW. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

 5. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each
signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Supplemental Indenture. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF
transmissions shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by
facsimile or PDF shall be deemed to be their original signatures for all purposes. 
 6. EFFECT OF HEADINGS. The Section headings herein are
for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof. 

7. THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiaries and the Company. 

8. RATIFICATION OF INDENTURE. Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms,
conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder heretofore and hereafter authenticated and delivered shall be bound hereby.

In the event more than one of (a) to (l) applies to any given amount, such amount shall be deducted only once for purposes of calculating Net Sales. If
Regeneron, its Affiliates or its Sublicensees receive non-cash consideration for any Licensed Product or in the case of any transfer of Licensed Product other than in a bona fide arms’ length sale, Net Sales will be calculated based on the fair
market value of such Licensed Product, assuming an arm’s length transaction made in the ordinary course of business. 
 Solely for purposes of
calculating Net Sales, if Regeneron or its Affiliate or Sublicensee sells any Combination Product, Net Sales of such Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product, as determined in the first
paragraph of this definition of “Net Sales”, by the fraction A/(A+B), where A is the invoice price of the Licensed Product, if sold separately, and B is the invoice price of the other active ingredient(s) in the combination, if sold
separately. If, on a country-by-country basis, such other active ingredient(s) in the Combination Product is not sold separately in such country, but the Licensed Product component of the Combination Product is sold separately in such country,
Net Sales for the Combination Product shall be calculated by multiplying actual Net Sales of the Combination Product by the fraction A/C, where A is the invoice price of the Licensed Product component, if sold separately, and C is the invoice price
of the Combination Product. If, on a country-by-

  
 9 

 
country basis, the Licensed Product component is not sold separately in that country, Net Sales for the Combination Product shall be calculated by multiplying actual Net Sales of the Combination
Product by the fraction D/(D+E), where D is the fair market value of the portion of the Combination Product that contains the Licensed Product and E is the fair market value of the portion of the Combination Product containing the other active

7.6    Post-Option Period Exclusivity. In the event Regeneron exercises the Option, neither
Collaborator nor any of its Affiliates will, [**]; provided that, Collaborator shall [**] of this Section 7.6 [**]. In the event of any Change of Control of Collaborator, the foregoing covenant by Collaborator

  
 21 

 
and its Affiliates will not apply to a Competing Product that is in advanced pre-clinical development (i.e., at least at the state where a lead clinical candidate has been identified), clinical
development, subject to an IND filing, under review for Regulatory Approval or being commercialized by a Third Party described in the definition of “Change of Control,” or such Third Party’s Affiliates (other than an Affiliate of
Collaborator prior to the Change of Control), prior to the closing of such Change of Control (such Competing Product, an “Acquirer Competing Product”); provided that (i) Collaborator[**] in connection with this Agreement and [**] pursuant
to this Agreement. [**] this Section 7.6[**] of this Section 7.6. 

7.7    Diligence. Following the exercise of the Option, Regeneron shall use Commercially
Reasonable Efforts to research, develop and commercialize at least one Licensed Product. For purposes of this Section 7.7, Commercially Reasonable Efforts shall be deemed not to have been met by Regeneron if the first dose of a Licensed Product
in the first clinical trial after the Collaboration Clinical Trial has not occurred by the earlier of (a) [**] after completion of the Collaboration Clinical Trial for such Licensed Product or (b) [**] after the initiation of IND Enabling GLP
Toxicology Studies for such Licensed Product; provided that, the time periods in subclauses (a) and (b) above shall be (i) extended and shall not expire if and for so long as Regeneron has not ceased research and development of all Licensed Products
without plans to resume such activities with respect to at least one Licensed Product within the succeeding [**] and (ii) tolled during any period of time that any clinical trial for a Licensed Product is ceased or delayed due to (1) communications
from a Regulatory Authority or (2) development of a delivery device intended for commercial Licensed Product that is to be used to in a clinical trial for such Licensed Product; provided that Regeneron is using commercially reasonable efforts to
resume such clinical trial or develop such device, as applicable. Commercially Reasonable Efforts shall apply on a Territory-wide basis and not on a country-by-country or jurisdiction-by-jurisdiction basis, meaning that the failure to use
Commercially Reasonable Efforts to develop or commercialize a Licensed Product in a particular country shall not be deemed a breach of this Section 7.7, unless such failure amounts to a failure to use Commercially Reasonable Efforts in the Territory
as a whole. Within [**] days after filing of a BLA for a Licensed Product, and at least [**] thereafter, the Parties shall meet and Regeneron shall provide Collaborator with a summary and update of commercialization activities and plans.

7.8    Sublicensing by Regeneron. Regeneron shall have the right, in its reasonable
discretion, to sublicense the Research License to its wholly-owned Affiliates and the Commercial License to its Affiliates and any Third Party, through multiple tiers. Regeneron shall remain liable for any breach of this Agreement by its
Sublicensees and Affiliates.

 8.2    Milestone
Payments. Regeneron shall notify Collaborator of the achievement by Regeneron, its Affiliate or Sublicensee of each milestone event set forth in Section 8.2.1 or 8.2.2 below and shall pay Collaborator the corresponding milestone payment
within [**] days after such achievement; provided that, if the First Development Milestone is achieved, but not pursuant to the proviso in the definition of “First Development Milestone” (i.e., [**]), then Regeneron, in its sole
discretion, may elect either to pay or not to pay the First Development Milestone, and the notice described in this Section 8.2 shall include such election. If Regeneron elects not to pay the First Development Milestone, then Collaborator shall have
the right to terminate this Agreement pursuant to Section 14.2.4. 
 8.2.1    Development
Milestones. Subject to the proviso in Section 8.2, Regeneron shall pay to Collaborator the milestone payments described in this Section 8.2.1 upon achievement (first occurrence) of the corresponding milestone event on a Licensed
Product-by-Licensed Product basis (i.e., payable for each Licensed Product that achieves such milestone).

 Each milestone payment payable by Regeneron pursuant to this Section 8.2.1 shall be payable only once for each Licensed
Product; provided that, if any Licensed Product achieves any development milestone event and the development or commercialization of such Licensed Product is subsequently ceased and another Licensed Product Directed to the same Licensed Target as
the ceased Licensed Product is substituted for such ceased Licensed Product, then, with respect to the substitute Licensed Product, payments for the achievement of the same milestone events that were achieved by such ceased Licensed Product and paid
by Regeneron shall not be payable. In addition, if for any reason a milestone event corresponding to a milestone payment in the table above does not occur prior to the occurrence of the next sequential milestone event in the table above (e.g.,
[**]), then such prior non-occurring milestone event shall be deemed to occur concurrently with the occurrence of such next sequential milestone event.

 Each milestone payment payable by Regeneron pursuant to this Section 8.2.2 shall be payable only once for all Licensed
Products. If for any reason a sales milestone event corresponding to a milestone payment in the table above does not occur prior to the occurrence of the next sequential milestone event in the table above (e.g., aggregate annual Net Sales for
all Licensed Products in a calendar year exceeds $[**], but the milestone for annual Net Sales exceeding $[**] was not previously paid), then such prior non-occurring milestone event shall be deemed to occur concurrently with the occurrence of such
next sequential milestone event. 
 8.3    Royalties. Regeneron shall pay to Collaborator,
on a Licensed Product-by-Licensed Product basis, a royalty on the Net Sales of each Licensed Product in the Territory as described in this Section 8.3. A royalty shall only be payable on Net Sales of a Licensed Product in any country in the
Territory that occur during the Royalty Term for such Licensed Product in such country.
 (a)    A royalty in the amount
of [**] percent ([**]%) on the portion of Net Sales that occur in the Territory less than or equal to [**] Dollars ($[**]) within a calendar year. 

(b)    A royalty in the amount of [**] percent ([**]%) on the portion of Net Sales that occur in the Territory over [**]
Dollars ($[**]) but less than or equal to [**] Dollars ($[**]) within a calendar year.
 (c)    A royalty in the amount
of [**] percent ([**]%) on the portion of Net Sales that occur in the Territory over [**] Dollars ($[**]) but less than or equal to [**] Dollars ($[**]) within a calendar year.

 8.4    Royalty Reductions & Adjustments.

(a)    In the event that Net Sales of a Licensed Product occur in any country during the Royalty Term, but in a period
when no Valid Claim exists in such country under (i) the [**] that, but for the licenses granted by this Agreement, would be infringed by the importing, selling or offering for sale of such Licensed Product in such country or (ii) [**] that remains
in effect and Covers the importing, offer for sale or sale of such Licensed Product in such country, then the royalty rate for royalties payable to Collaborator under Section 8.3 with respect to such Net Sales shall be reduced by [**] percent
([**]%). 
 (b)    In the event that Regeneron enters into one or more Patent licenses from any Third Party in order to
make, use, sell, offer for sale or import a Licensed Product in any country in the Territory and such license is [**] (hereinafter “Third Party Patent Licenses”), then [**] percent ([**]%) of [**] (“Third Party Payment
Reduction”) shall be creditable against the royalty payments due to Collaborator based on Net Sales of such Licensed Product in such country under Section 8.3; provided, however, that no such credit may reduce any royalty payment by more
than [**] percent ([**]%) of the royalty payment that would have been due absent this Section 8.4(b). 
 (c)    In the
event that any Third Party sells a Competing Product to any Licensed Product in any country in the Territory without the approval of, or the grant of a license from, Regeneron: (i) at the time of [**], then the royalty rate for royalties payable to
Collaborator under Section 8.3 for Net Sales of the applicable Licensed Product shall be reduced by [**]%; or (ii) at any subsequent time and, following the first commercial sale of such Competing Product in such country, [**], the royalty rate for
royalties payable to Collaborator under Section 8.3 for Net Sales of the applicable Licensed Product in such country shall be reduced by [**] percent ([**]%).

(d)    If, in any Calendar Quarter any of the royalty reductions described in Sections 8.4(a), 8.4(b) or 8.4(c) apply in
one or more but not all countries in the Territory and Net Sales in the Territory in such Calendar Quarter exceed one or more of the royalty percentage tiers described in Section 8.3, then such royalty reductions shall be applied to Net Sales in
each such percentage tier in the same proportion as (i) the Net Sales to which such royalty reductions apply bear to (ii) the aggregate Net Sales subject to royalty payments in such Calendar Quarter.

(e)    In no event shall the royalties paid by Regeneron to Collaborator in any Calendar Quarter be reduced pursuant to
Sections 8.4(a), 8.4(b) and/or 8.4(c) to less than [**] percent ([**]%) of the amounts that would be owed in the absence of such reductions. [**]. 

8.5    Royalty Reports and Payments. Commencing with the Calendar Quarter in which the
First Commercial Sale of a Licensed Product by Regeneron its Affiliates or Sublicensees occurs, until the Calendar Quarter in which the expiration of the Royalty Term for all Licensed Products in the Territory occurs, Regeneron shall make written
reports to Collaborator within [**] days after the end of each such Calendar Quarter, stating in each such report the Net Sales in Dollars of each Licensed Product sold during such Calendar Quarter by Regeneron, its Affiliates or Sublicensees and
the calculation of royalty payments due to Collaborator on such Net Sales. Regeneron shall pay to Collaborator the total royalties, if any, due for the 

  
 25 

 
period of the report required in this Section 8.5, within [**] days following delivery of such report. If no royalties are due, Regeneron shall so report. An example of the report
required by this Section 8.5, including examples of the calculation of royalties and royalty reductions, is set forth in the Royalty Calculation Appendix attached hereto. 

8.6    Regeneron Reimbursable Cost Reporting and Reimbursement. For each Calendar Quarter
commencing with the first Calendar Quarter in which Regeneron Reimbursable Costs are incurred by Regeneron, Regeneron shall provide to Collaborator within [**] days following the end of each such Calendar Quarter a written report (in electronic
form) summarizing the material activities undertaken by Regeneron during such Calendar Quarter together with a statement of the corresponding Regeneron Reimbursable Costs incurred by Regeneron during such Calendar Quarter. Within [**] days
following the delivery of the report required by this Section 8.6, Collaborator shall pay to Regeneron the total undisputed amount of Regeneron Reimbursable Costs specified in such report. Notwithstanding the foregoing, Collaborator shall not be
obligated to pay Regeneron Reimbursable Costs if and to the extent such payment would result in the aggregate amount of Collaborator’s payments under this Section 8.6 to exceed the Regeneron Reimbursable Costs Cap. 

8.7    Audit Rights. Collaborator shall have the right to audit Regeneron’s and its
Affiliates’ records relating to royalty reports and Regeneron Reimbursable Cost reports at Collaborator’s own expense, but only to the extent such records are reasonably required to verify the royalties or Regeneron Reimbursable Costs
payable under this Agreement. Collaborator shall have the right to engage an independent, certified, internationally-recognized public accounting firm reasonably acceptable to Regeneron to inspect Regeneron’s relevant records; provided,
however, that such auditor shall not disclose Regeneron’s Confidential Information to Collaborator, except to the extent such disclosure is necessary to verify the amount of royalties or Regeneron Reimbursable Costs due under this
Agreement. Collaborator may exercise such inspection right upon reasonable advance notice to Regeneron and only during normal business hours during the term of this Agreement and within [**] years after its termination or expiration. Such
inspections may be exercised [**], within [**] years after the applicable payment was made to which such records relate, and any data and information relating to any particular payment shall be audited only once. Any amounts shown to be owing
by any such audit by one Party to the other shall be paid promptly, together with interest calculated as set forth in Section 8.9. If any audit reveals an underpayment or overcharge by Regeneron that exceeds [**] percent ([**]%) of the amount
actually due to or payable by Collaborator in respect of any Calendar Quarter, then Regeneron shall pay Collaborator’s expenses for the audit in addition to the underpaid or overcharged amount. 

  
 26 

 8.8    Payments. All payments under this
Agreement shall be made in U.S. Dollars by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. In those cases where the amount due in U.S. Dollars is calculated based upon one
or more currencies other than U.S. Dollars, such amounts shall be converted to U.S. Dollars at the average rate of exchange for the Calendar Quarter to which such payment relates using the arithmetic mean of the daily rate of exchange (Mid Price
Close), as reported in Thomson Reuters Eikon, or any other source as agreed to by the Parties.

8.9    Late Payments. The paying Party shall pay interest to the other Party on the aggregate
amount of any payment that is not paid on or before the date such payment is due under this Agreement at a rate equal to the one month London Inter-Bank Offering Rate (LIBOR) U.S. Dollars, as quoted on Thomson Reuters Eikon, or any other
source as agreed to by the Parties, effective from the date on which the payment was due, [**] unless such payments are disputed in good faith. The Parties agree that if there is a good faith dispute regarding any payment amount, (a) only the
disputed amount shall be withheld from the payment and the undisputed amount shall be paid within the timeframes set forth in this ARTICLE 8 and (b) this provision shall not apply to such disputed amount during the pendency of such dispute. 

8.10    Tax. Regeneron will make all payments to Collaborator under this Agreement without
deduction or withholding for Taxes except to the extent that any such deduction or withholding for Taxes is required by Applicable Laws. Any Tax required to be withheld under Applicable Laws on amounts payable to Collaborator under this
Agreement will promptly be paid by Regeneron on behalf of Collaborator to the appropriate Governmental Authority, and Regeneron will furnish Collaborator with proof of payment of such Tax as soon as practicable. Any such Tax required to be
withheld will be an expense of and borne by Collaborator. The Parties will cooperate to secure a reduction in the rate of applicable Taxes withheld. Regeneron will make payments to Collaborator under this Agreement from an entity domiciled
in the United States, Ireland, or any jurisdiction that does not require withholding for payments to the United States.

Know-How, Patents and copyrights) that are conceived or made solely by employees, sublicensees, independent contractors, agents or consultants of such Party or its Affiliates, or other individuals having an obligation to assign such Other
Collaboration Inventions solely to such Party or its Affiliates or for which ownership vests in such Party or its Affiliates by operation of law (such employees, sublicensees, independent contractors, agents, consultants or other individuals,

 (d)    With regards to Other
Collaboration Inventions that are conceived or made jointly by Personnel of Collaborator or its Affiliates or for which ownership vests in Collaborator or its Affiliates by operation of law, on the one hand, and by Personnel of Regeneron or its
Affiliates or for which ownership vests in Regeneron or its Affiliates by operation of law, on the other hand, the Parties shall jointly own all such inventions and intellectual property rights therein (including Know-How, Patents and copyrights),
with each Party having an equal, undivided interest therein (“Joint Inventions”).

further action by any Party.
 (g)    Each Party shall have an equal, undivided interest in Joint Inventions, which may
be sublicensed to Third Parties, and any ownership rights therein may be transferred, in whole or in part, by each Party without consent of the other Party, unless otherwise prohibited by this Agreement and subject to any licenses thereunder granted
under this Agreement; provided, however, that [**] nothing in this ARTICLE 9 shall relieve a Party or its Affiliates of their obligations under ARTICLE 10 with respect to Confidential Information of any Party provided by the other Party or such
other Party’s Affiliates. Neither Party hereto shall have the duty to account to the other Party for any revenues, profits or rights obtained from any transfer of its interest in, or its use, sublicense or other exploitation of, a Joint
Invention outside the scope of this Agreement. To the extent necessary to effect the intent of this Section 9.1(g), each Party grants to the other Party a nonexclusive, royalty-free, worldwide, sublicensable license under such Party’s
interest in Joint Inventions, and all intellectual property rights therein, to make, use, sell, offer for sale and import the relevant Joint Invention, for all purposes.

Party. 
 10.3    Authorized Disclosures of Confidential Information. Notwithstanding the
foregoing, a Party may use and disclose the Confidential Information of the other Party as follows: 
 (a)    to the
extent required by law, rule, governmental regulation or request from a Governmental Authority, including as may be required in connection with any filings made with, or by the disclosure policies of, a major stock exchange; provided that the Party
seeking to disclose the Confidential Information of the other Party shall (i) use all reasonable efforts to inform the other Party prior to making any such disclosures and cooperate with the other Party in seeking a protective order or other
appropriate remedy (including redaction) and (ii) whenever possible, request confidential treatment of such information; 

(b)    subject to Sections [**] and [**], to the extent such use and disclosure is reasonably required in the filing,
prosecution, maintenance or publication of any patent application or patent on inventions;

case, under obligations of confidentiality at least as restrictive as those used by the receiving Party to protect its own proprietary or confidential information, but no less restrictive than standard practice in the biotechnology industry, in each
case who have a need to know such information (i) in connection with such Party performing its obligations or exercising its rights under this Agreement or, (ii) with respect to actual or potential acquirers, merger partners and sources of financing
only, for the purpose of evaluating and entering into a transaction with such party; or 
 (f)    a Party may disclose
the existence and terms of this Agreement where required, as reasonably determined by the legal counsel of the disclosing Party, by Applicable Law or by applicable stock exchange regulation, although, to the extent practicable, the other Party
shall, subject to the next sentence of this Section 10.3(f), be given at least [**] Business Days’ advance written notice of any such required disclosure to comment and the disclosing Party shall reasonably consider such comments provided by
such other Party on the proposed disclosure. In case either Party is obliged to publicly disclose or file this Agreement as a “material agreement” in accordance with Applicable Law or applicable stock exchange regulations
(“SEC Filing”), this Agreement shall be redacted by the filing Party to the extent permissible upon the advice of legal counsel, and the filing Party shall provide the other Party a copy of such redacted Agreement as soon as
reasonably available prior to the date of filing, but in no event later than [**] Business Days in advance of such SEC Filing to enable the other Party to review and comment on the scope of such redaction (such [**] Business Day period, the
“SEC Filing Comment Period”). The filing Party shall consider the comments of the reviewing Party in good faith. The filing Party shall not be obligated to accept comments contrary to the advice of its legal counsel. With
respect to any comments of the reviewing Party made prior to the expiration of the first [**] days of the SEC Filing Comment Period, (a) the filing Party shall promptly notify the reviewing Party of any unaccepted comments and (b) the filing Party

management and securities counsel to resolve such comments no later than [**] days prior to the expiration of the SEC Filing Comment Period. Notwithstanding the foregoing, neither Party shall be required to again provide to the other Party for
comment and review any proposed redacted Agreement in connection with an SEC Filing where such redactions have previously been publicly disclosed or filed in accordance with this Section 10.3(f). The Parties acknowledge that Collaborator
intends to file a Current Report on Form 8-K pursuant to the Securities Exchange Act of 1934 in connection with the entry into this Agreement (the “Form 8-K”). Collaborator agrees that the Form 8-K shall be in the form
set forth on the 8-K Exhibit to this Agreement.

 10.4    Terms of this Agreement. The Parties
agree that this Agreement and the terms hereof will be considered Confidential Information of both Parties but can be disclosed as provided under Section 10.3. 

10.5    Research Results. Research Results are the Confidential Information of
Regeneron. Regeneron hereby consents to Collaborator’s use and disclosure of Research Results solely as described in this Section 10.5. Collaborator may use Research Results for (a) conducting its activities related to this Agreement,
(b) [**], and, (c) subject to Section 9.2(f) and Section 9.2(g), the filing and prosecution of Patents claiming Collaborator Technology Inventions or Collaborator Sole Inventions or, subject to Section 9.2(d) and Section 9.2(e), Joint
Patents. Collaborator may disclose Research Results [**] to Third Parties; provided that, (x) such disclosure is subject to confidentiality restrictions at least as restrictive as those contained herein and any Publication of such Research
Results is subject to the same consent and review rights as set forth in Section 11.2 (to the same extent as if Collaborator were making such Publication), (y) the identity of any Licensed Target, Collaboration Therapeutic Molecule, or Licensed
Product has been removed and (z) any mention of Regeneron in relation to such Research Results has been removed. 

10.6    No License. As between the Parties, Confidential Information disclosed hereunder
shall remain the property of the disclosing Party. Disclosure of Confidential Information to the other Party shall not constitute any grant, option or license to the other Party, beyond those licenses expressly granted hereunder, under any
Patent, trade secret or other rights now or hereinafter held by the disclosing Party. 
 ARTICLE 11 

PUBLICITY; PUBLICATIONS 

11.1    Publicity. Except as permitted in ARTICLE 10 or this Section 11.1, neither Party
shall issue any press release or other public announcement concerning this Agreement without the prior written approval of the other Party.

11.1.1    By Regeneron. Regeneron may issue any press release or other public announcement concerning any Licensed
Product following its exercise of the Option and payment of the Option Exercise Fee, provided that Regeneron shall use reasonable efforts to give Collaborator a reasonable opportunity to review and comment on the contents of each such press release
prior to its issuance and Regeneron shall give good faith consideration to Collaborator’s comments that are submitted to Regeneron within [**] Business Days of Regeneron’s provision of the draft press release or other public announcement,
or such shorter period as Regeneron has been advised by legal counsel, otherwise Collaborator’s review and comment rights shall be deemed waived with respect to such press release or public announcement. 

  
 34 

 11.1.2    By Collaborator. Collaborator may issue the press
release set forth in the Initial Press Release Appendix attached hereto following the Effective Date. Collaborator may issue additional press releases regarding Regeneron’s exercise of the Option, achievement of any development or
sales milestone event hereunder, or receipt of any Regulatory Approval of any Licensed Product, provided that Collaborator gives Regeneron a reasonable opportunity to review and comment on the contents of each such press release prior to its
issuance and Collaborator shall give good faith consideration to Regeneron’s comments that are submitted to Collaborator within [**] Business Days of Collaborator’s provision of the draft press release or other public announcement, or such
shorter period as Collaborator has been advised by legal counsel, otherwise Regeneron’s review and, comment rights shall be deemed waived with respect to such press release or public announcement. Notwithstanding the foregoing,
Collaborator shall not be permitted to make any press release or other public disclosure that includes non-public information relating to a Licensed Product (other than the achievement of any development or sales milestone event hereunder) without
Regeneron’s prior written consent. 
 11.2    Publications. Neither Party shall disclose to
Third Parties any papers, presentations, posters, slides, abstracts, manuscripts, marketing materials, or make any other similar disclosure to Third Parties (“Publication”) that (a) includes Research Results, identifies the other
Party or any Licensed Product or, in the case of Collaborator, discloses the fact that Regeneron is pursuing any Licensed Product or (b) otherwise concerns any aspect of this Agreement or the activities performed hereunder (except to the extent
expressly permitted by the terms of this Agreement), in each case, without the express written consent of the other Party. Regeneron shall be permitted to make any Publication concerning any Licensed Product following its exercise of the Option
without restriction except as to Confidential Information of Collaborator as provided below. With respect to any Publication proposed by Regeneron which utilizes Research Results, Collaborator shall have the right to review any such
Publication. Regeneron shall submit to Collaborator the proposed Publication at least [**] calendar days prior to the date of submission for publication or the date of presentation, whichever is earlier. Collaborator shall review such
submitted materials and respond to Regeneron within a reasonable time, but in any case within [**] calendar days of receipt thereof. At the option of Collaborator, Regeneron shall (i) delete from such proposed publication or presentation any
Confidential Information of Collaborator or (ii) delay the date of submission or presentation for a period of time sufficiently long (but in no event longer than [**] calendar days) to permit Collaborator to seek appropriate patent
protection. Once a Publication has been approved by Collaborator (or to the extent information in any proposed Publication is then available to the public), either Party may make subsequent public disclosure of the contents of such Publication
(or other public information) without the further approval of the other Party; provided such content is not presented with any new data or information or conclusions or in a form or manner that materially alters the subject matter therein. For
clarity, this Section 11.2 shall not prohibit Collaborator’s disclosure of [**] to a Third Party under the conditions described in Section 10.5. 

  
 35 

 11.3    No Right to Use Names. Except as
expressly provided herein, no right, express or implied, is granted by this Agreement to any Party to use in any manner the name of the other Party or its Affiliates or any other trade name, symbol, logo or trademark of the other Party or its
Affiliates in connection with the performance of this Agreement; provided that, without Collaborator’s consent, Regeneron may state that Regeneron is licensed by Collaborator under the Collaborator Intellectual Property.

12.4    Disclaimers. EXCEPT AS OTHERWISE EXPRESSLY STATED IN THIS AGREEMENT, NEITHER PARTY
MAKES ANY REPRESENTATION OR WARRANTY OF ANY KIND WITH RESPECT TO PATENTS, KNOW-HOW, MATERIALS OR CONFIDENTIAL INFORMATION SUPPLIED BY IT TO THE OTHER PARTY HEREUNDER, AND EXPRESSLY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES

ARTICLE 13 

INDEMNIFICATION; LIABILITY 

13.1    Indemnification. Subject to Section 13.2, each Party shall indemnify, defend and hold
each of the other Party, its Affiliates and their respective directors, officers, employees, consultants, licensors, and agents 

  
 40 

 
and the successors and assigns of any of the foregoing harmless from and against any and all liabilities, damages, settlements, penalties, fines, costs or expenses (including, without limitation,
reasonable attorneys’ or accountants’ fees and other expenses of litigation) (collectively, “Losses”) arising, directly or indirectly out of or in connection with any Third Party claims, suits, actions, demands or
judgments (“Third Party Claims”) to the extent resulting from (a) the gross negligence or willful misconduct of such Party in the performance of its obligations under this Agreement, (b) breach by such Party of the representations,
warranties, or covenants made in this Agreement, (c) in the case of Regeneron’s obligation as an Indemnitor, the development or commercialization of any Licensed Product sold by Regeneron or its Affiliates or Sublicensees, but excluding any
such Third Party Claim to the extent such Third Party Claim concerns or arises from Collaborator Intellectual Property incorporated into any Licensed Product, including any claim of infringement of any intellectual property of any Third Party based
upon such Collaborator Intellectual Property; provided neither Party shall be required to indemnify the other Party to the extent such Losses result from (i) the gross negligence or willful misconduct of the other Party under this Agreement, or (ii)
breach by the other Party of the representations, warranties, or covenants made in this Agreement. 

13.2    Procedure. If a Party intends to claim indemnification under this Agreement (the
“Indemnitee”), it shall promptly notify the other Party (the “Indemnitor”) in writing of the applicable Third Party Claim and potential Loss. The Indemnitor shall have the right to control the defense thereof
with counsel of its choice as long as such counsel is reasonably acceptable to the Indemnitee. Any Indemnitee shall have the right to retain its own counsel at its own expense for any reason. The Indemnitee, its employees and agents, shall
reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Third Party Claims covered by this Agreement. The Indemnitor shall obtain the written consent of the Indemnitee before settling any Third Party
Claim; provided that, the Indemnitor shall not need the consent of the Indemnitee hereunder for any settlement that includes a complete and unconditional release of the Indemnitee from all liability with respect thereto and that imposes no liability
or obligation on the Indemnitee (other than the obligation to pay money damages that are subject to payment by the Indemnitor). The failure to deliver timely written notice to the Indemnitor within a reasonable time after the commencement of
any Third Party Claim shall not relieve the Indemnitor of its obligations to the Indemnitee under Section 13.1, except to the extent the Indemnitor is prejudiced by such delay or failure. It is understood that only Regeneron and Collaborator
may claim indemnity under this Agreement (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not claim indemnity hereunder. 

  
 41 

 13.3    Insurance. Each Party will maintain, for
the duration of this Agreement, insurance in an amount reasonably adequate to cover its obligations hereunder. 

13.4    Limitation of Damages. NEITHER PARTY HERETO WILL BE LIABLE FOR INDIRECT, INCIDENTAL,
CONSEQUENTIAL, SPECIAL OR EXEMPLARY DAMAGES ARISING FROM OR RELATING TO THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT IN RESPECT OF ANY BREACH OF A PARTY’S CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE 10, EXCLUSIVITY OBLIGATIONS
UNDER SECTION 7.3 OR SECTION 7.6, OR INDEMNIFICATION OBLIGATIONS UNDER THIS ARTICLE 13 FOR THIRD PARTY CLAIMS OR EITHER PARTY’S, ITS AFFILIATES’ OR ITS OR THEIR PERSONNELS’ GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 

ARTICLE 14 
 TERM
AND TERMINATION 
 14.1    Term. The term of this Agreement (the
“Term”) shall commence on the Effective Date and, unless earlier terminated, will expire as set forth below: 

(a)    If Regeneron has exercised the Option, this Agreement will expire on a Licensed Product-by-Licensed Product and
country-by-country basis, upon the expiration of the applicable Royalty Term for a Licensed Product in a country. Following such expiration of this Agreement, Collaborator hereby grants to Regeneron a perpetual, sublicensable, fully paid-up,
non-exclusive license under the Collaborator Know-How to conduct research and to develop, make, have made, use, sell, offer for sale and import Licensed Products in the Field in the Territory. 

(b)    If Regeneron has not exercised the Option, this Agreement will expire upon the expiration of the Option Period.

 14.2    Termination.

14.2.1    Termination for Convenience. Following the exercise of the Option, Regeneron may terminate this
Agreement as to any or all Licensed Products at any time upon providing sixty (60) days’ prior written notice to Collaborator.

14.2.2    Material Breach. Either Party may terminate this Agreement in the event of a material breach by the
other Party of any of its obligations under this Agreement. The Party seeking to terminate must provide written notice of the material breach to the other Party, and termination will not become effective if the other Party cures such breach
within [**] days’ receipt of written notice thereof (or [**] days in the case of a payment breach, provided, however, that Collaborator shall have the additional cure period provided under Section 8.2.1 in the event of the circumstances
described therein), or, if applicable, such longer period, but not to 

  
 42 

 
exceed [**] days, as would be reasonably necessary to cure such material breach that is not a payment breach, provided the breaching Party has commenced and continues its Commercially Reasonable
Efforts to cure during the initial [**]day period following the date on which the breach notice is provided and throughout the extended cure period). For purposes of this Section 14.2.2, the term “material breach” shall mean a breach
by a Party that substantially undermines the benefits reasonably expected to be realized by the non-breaching Party from this Agreement, taken as a whole; provided that any failure of a Party to make undisputed payments to the other Party shall be
deemed a “material breach”. In the event of any bona-fide, good-faith dispute as to whether a material breach has occurred, the Party seeking to terminate this Agreement shall not have the right to do so until the matter is finally,
judicially determined (or, upon mutual agreement of the Parties, determined by arbitration or otherwise settled by the Parties). 

14.2.3    Insolvency or Bankruptcy. Either Party may terminate this Agreement effective upon written notice to
the other Party upon the liquidation, dissolution, winding up, insolvency, bankruptcy, or filing of any petition therefor, appointment of a receiver, custodian or trustee, or any other similar proceeding, by or of the other Party where such
petition, appointment or similar proceeding is not dismissed or vacated within [**] calendar days and where such petition, appointment or similar proceeding is not a part of any bona fide reorganization of a Party or its Affiliates. All
rights and licenses granted under or pursuant to this Agreement by a Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under
Section 101 of the U.S. Bankruptcy Code. The Parties agree that Regeneron, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or any other
provisions of Applicable Law outside the United States that provide similar protection for “intellectual property.” The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Collaborator
under the U.S. Bankruptcy Code or analogous provisions of Applicable Law outside the United States, Regeneron shall be entitled to a complete duplicate of (or complete access to, as appropriate) any Collaborator Intellectual Property and all
embodiments of such Collaborator Intellectual Property, which, if not already in Regeneron’s possession, shall be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon Regeneron’s written request therefor,
unless Collaborator elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under clause (i) above, following the rejection of this Agreement by or on behalf of Collaborator upon written request therefor by
Regeneron. Any agreements supplemental hereto will be deemed to be “agreements supplementary to” this Agreement for purposes of Section 365(n) of the Bankruptcy Code. Any payments (whether royalties or otherwise) which have
become due or relate to any Net Sales made prior to the date of termination, shall remain due and owing following termination and become immediately payable upon termination. 

14.2.4    Election Not to Pay First Development Milestone. If Regeneron elects not to pay the First
Development Milestone pursuant to Section 8.2, then Collaborator may terminate this Agreement upon [**] days’ prior written notice; provided that, if Regeneron pays the First Development Milestone within such [**] day notice period, then this
Agreement shall not terminate. For clarity, in the event Regeneron does not pay the First Development Milestone under the circumstances described in Section 8.2, then such milestone shall be deemed to not

  
 43 

 
have been achieved and the payment associated with such milestone shall be deemed to not have accrued, in each case, for all purposes under this Agreement (including for purposes of the survival
of ARTICLE 8 under Section 14.3.5). 
 14.3    Effect of Expiration or Termination. In
addition to any rights or obligations expressly provided in this Agreement to apply upon termination or expiration of this Agreement, the provisions set forth in this Section 14.3 shall apply to any expiration or termination of this Agreement. 

14.3.1    Accrued Rights and Obligations. Expiration or termination of this Agreement for any reason shall not
release either Party hereto from any liability which, as of the effective date of such expiration or termination, had already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from
pursuing any rights and remedies it may have hereunder or at law or in equity which accrued, or are based upon any event occurring, prior to the effective date of such expiration or termination. 

14.3.2    Termination by Collaborator for Material Breach, Insolvency or Election Not to Pay First Development Milestone;
or by Regeneron for Convenience. Upon termination of this Agreement (i) by Collaborator for material breach pursuant to Section 14.2.2, bankruptcy or insolvency pursuant to Section 14.2.3 or Regeneron’s election not to pay the First
Development Milestone pursuant to Section 14.2.4 or (ii) by Regeneron for convenience pursuant to Section 14.2.1: 

(a)    all rights and licenses granted to either Party by the other Party pursuant to this Agreement shall automatically
and immediately terminate; 
 (b)    Collaborator shall return to Regeneron all Regeneron Material that is in the
possession of Collaborator; 
 (c)    Regeneron shall return to Collaborator all Collaborator Material that is in the
possession of Regeneron; and 
 (d)    except in the case of a termination by Regeneron for convenience pursuant to
Section 14.2.1 or by Collaborator for Regeneron’s election not to pay the First Development Milestone pursuant to Section 14.2.4, any sublicense granted by Regeneron under the Commercial License, if granted prior to such termination in
compliance with this Agreement, shall remain in full force and effect pursuant to the terms thereof, notwithstanding such termination; provided that the applicable Sublicensee is then in good standing and has not contributed to the breach or other
circumstance that led to the termination of this Agreement, and all payments and other obligations due under any such sublicense to Regeneron shall become immediately due to Collaborator instead of Regeneron; further provided, however, that
Collaborator shall have no obligation to perform any activities under such sublicense that extend beyond Collaborator’s obligations under this Agreement. 

14.3.3    Termination by Regeneron for Material Breach or Insolvency. Upon termination by Regeneron of this
Agreement for material breach pursuant to Section 14.2.2 or insolvency or bankruptcy pursuant to Section 14.2.3:

  
 44 

 (a)    all rights and licenses granted to Collaborator by Regeneron pursuant
to this Agreement shall automatically and immediately terminate; and 
 (b)    Collaborator shall return to Regeneron
all Regeneron Material (other than the Research Results) in the possession of Collaborator. 
 14.3.4    Return of
Confidential Information. It is understood and agreed, that each Party shall have a continuing right to use Confidential Information of the other Party to the extent necessary to exercise any surviving rights, licenses or obligations under
this Agreement. Subject to the foregoing, following expiry or any early termination of this Agreement, the Party that has Confidential Information of the other Party shall destroy (at such other Party’s written request) all such
Confidential Information in its possession as of the effective date of expiration or termination (with the exception of one copy of such Confidential Information, which may be retained by the legal department of the Party that received such
Confidential Information to confirm compliance with the non-use and non-disclosure provisions of this Agreement). 

14.3.5    Survival. In addition to any provisions that specify survival or non-survival in the event of
expiration or termination of this Agreement, the provisions of Sections 2.5, 2.7, 4.3 (to the extent Regeneron retains the Commercial License or the perpetual license under Section 14.1(a) after such expiration or termination), 5.2 (to the
extent Regeneron retains the Commercial License or the perpetual license under the second sentence of Section 14.1(a) after such expiration or termination), 8.7, 9.1, 9.2(a), 9.2(d), 9.2(e), 9.2(f), 9.2(g), 9.2(h) (solely with respect to other
surviving provisions in ARTICLE 9), 9.3 (solely with respect to Joint Patents), 9.4(e), 9.4(h), 12.4, 12.5, 13.1, 13.2, 13.4, 14.1(a) (the second sentence) and 14.3 and, ARTICLE 1, ARTICLE 8 (with respect to payments accrued prior to the expiration
or termination of this Agreement), ARTICLE 10 and ARTICLE 16, shall survive any termination or expiration of this Agreement. 

14.3.6    Additional Remedy of Regeneron for Material Breach by Collaborator. In the event Regeneron has the
right to terminate this Agreement for material breach pursuant to Section 14.2.2, then, instead of termination and in addition to any other rights and remedies of Regeneron in equity in respect of such material breach, upon Regeneron’s
election: 
 (a)    [**], 

(b)    [**]. 

ARTICLE 15 
 FORCE
MAJEURE 
 In this Agreement, “Force Majeure” means any act of God, strike, lock-out or other material industrial/labor
disputes (whether involving the workforce of the Party so prevented or of any other Person), war, riot, civil commotion, terrorist act, epidemic, quarantine, fire, flood, storm, natural disaster or similar event which is beyond a Party’s
reasonable control and prevents such Party from performing its obligations under this Agreement. The Party affected by the Force Majeure shall, within [**] days after the occurrence of a Force Majeure event, give notice in writing to the other
Party specifying the nature and extent of the event of Force Majeure, its 

  
 45 

 
anticipated duration and any action being taken to avoid or minimize its effect. Subject to providing such notice and to such Party’s other obligations under this ARTICLE 15, the Party
invoking a Force Majeure event shall not be liable for delay in performance or for non-performance of its obligations under this Agreement (other than any payment obligation), in whole or in part, nor shall the other Party have the right to
terminate this Agreement, except as otherwise provided in this Agreement, where non-performance or delay in performance has resulted from an event of Force Majeure. The suspension of performance allowed hereunder shall be of no greater scope
and no longer duration than is reasonably required. The Party invoking a Force Majeure event shall use commercially reasonable efforts, to (a) bring the Force Majeure event to a close or (b) find a solution by which the Agreement may be
performed despite the continuation of the event of Force Majeure. 
 ARTICLE 16

16.4    Entire Agreement. This Agreement contains the complete understanding of the Parties
with respect to the subject matter hereof and supersedes all prior understandings and writings relating to the subject matter hereof and thereof. For clarity, this Agreement supersedes the Prior Agreements. 

  
 47 

 16.5    Amendments. No provision in this
Agreement shall be supplemented, deleted or amended except in a writing executed by an authorized representative of each of Collaborator and Regeneron. 

16.6    Interpretation. The captions to the several Articles and Sections of this Agreement
are included only for convenience of reference and shall not in any way affect the construction of, or be taken into consideration in interpreting, this Agreement. In this Agreement: (a) the word “including” shall be deemed to be
followed by the phrase “without limitation” or like expression; (b) references to the singular shall include the plural and vice versa; (c) references to masculine, feminine and neuter pronouns and expressions shall be interchangeable; (d)
the words “herein” or “hereunder” relate to this Agreement; (e) the words “shall” and “will” have the same meaning; (f) references to a particular statute or regulation include all rules and regulations
thereunder and any predecessor or successor statute, rules or regulation, in each case as amended or otherwise modified from time to time; (g) references to a particular person include such person’s successors and assigns to the extent not
prohibited by this Agreement; (h) unless otherwise specified, “$” is in reference to United States dollars; and (i) the word “or” has the inclusive meaning represented by the phrase “and/or”.

16.7    Construction. The Parties acknowledge and agree that: (a) each Party and its counsel
reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (b) the rule of construction to the effect that any ambiguities are resolved against the drafting Party will not be employed in the
interpretation of this Agreement; and (c) the terms and provisions of this Agreement will be construed fairly as to each Party and not in favor of or against either Party, regardless of which Party was generally responsible for the preparation of
this Agreement.
 16.8    Severability. To the fullest extent permitted by Applicable Law,
the Parties waive any provision of law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect. If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect, then
such provision will be given no effect by the Parties and shall not form part of this Agreement. To the fullest extent permitted by Applicable Law and if the rights or obligations of any Party will not be materially and adversely affected, all
other provisions of this Agreement shall remain in full force and effect, and the Parties shall use their best efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable
Law and achieves, as nearly as possible, the original intention of the Parties. 

16.9    Assignment. Neither Party shall assign any of its rights and obligations hereunder
without the prior written consent of the other Party, except (a) to a purchaser of all or substantially all of the assets or business of a Party to which this Agreement relates, or to the successor resulting from any

  
 48 

 
merger, acquisition, consolidation or similar transaction with such Party or (b) to an Affiliate; provided, however, that (i) such assignment to an Affiliate shall not relieve the assigning Party
of any of its liability hereunder and, (ii) in each case, the assigning Party shall provide the other Party with written notice of such assignment. In the event of any assignment described in subsection (a), no intellectual property rights of
the acquiring Person shall be included in the technology licensed to the other Party hereunder, unless such intellectual property rights arise as a result of the performance of this Agreement by or on behalf of such Person after such transaction
becomes effective. Any assignment or attempted assignment by either Party in violation of the terms of this Section 16.9 shall be null and void. 

16.10    Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the Parties hereto and their respective successors and permitted assigns, and shall also inure to the benefit of each Party’s Indemnitees. 

16.11    Signatures. This Agreement may be executed in counterparts, each of which shall be
deemed an original but which together shall constitute one and the same instrument. An executed signature page of this Agreement delivered by facsimile transmission or by electronic mail in “portable document format”
(“.pdf”) shall be as effective as an original executed signature page. 
 16.12    Third
Party Beneficiaries. None of the provisions of this Agreement shall be for the benefit of or enforceable by any Third Party, including any creditor of any Party hereto. No Third Party shall obtain any right under any provision of this
Agreement or shall by reason of any such provision make any claim in respect of any debt, liability or obligation (or otherwise) against any Party hereto. Notwithstanding the foregoing, Section 13.1 is intended to benefit, in addition to the
Parties, each Party’s Indemnitees as if they were parties hereto, but this Agreement is enforceable only by the Parties.

16.13    Relationship of the Parties. Each Party shall bear its own costs incurred in the
performance of its obligations hereunder without charge or expense to the other Party except as expressly provided in this Agreement. Neither Collaborator nor Regeneron shall have any responsibility for the hiring, termination or compensation
of the other Party’s employees or for any employee compensation or benefits of the other Party’s employees. No employee or representative of a Party shall have any authority to bind or obligate the other Party to this Agreement for
any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, and notwithstanding any other provision of this Agreement to the contrary,
Regeneron’s legal relationship under this Agreement to Collaborator, and Collaborator’s legal relationship under this Agreement to Regeneron, shall be that of an independent contractor. Nothing in this Agreement shall be construed to
establish a relationship of partners or joint ventures between the Parties or any of their respective Affiliates. 

  
 49 

 16.14    Injunctive or Other Equity
Relief. Nothing contained in this Agreement shall deny any Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm.

 16.15    Non-Exclusive Remedies. The rights and remedies provided herein are cumulative
and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as and to the extent expressly set forth herein.

Company to host conference call today at 8:30am Eastern Time 

BEDFORD, Mass, October X, 2016 – Ocular Therapeutix, Inc. (NASDAQ: OCUL), a biopharmaceutical company focused on the development and
commercialization of innovative therapies for diseases and conditions of the eye, today announced that it has entered into a strategic collaboration, option and license agreement with Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN). Ocular and
Regeneron will collaborate on the development of a sustained release formulation of the vascular endothelial growth factor (VEGF) trap aflibercept for the treatment of wet age-related macular degeneration (wet AMD) and other serious retinal
diseases. This formulation is currently in preclinical development. Regeneron’s aflibercept is currently approved by the U.S. Food and Drug Administration for certain indications under the brand name EYLEA®. 
 Ocular Therapeutix is currently developing proprietary sustained-release hydrogel-based drug
delivery depots for intravitreal injection that can be formulated with both small and large molecule pharmaceuticals, such as tyrosine kinase inhibitors (TKIs) and protein-based anti-VEGFs, respectively, with the goal of delivering sustained and
therapeutic levels of drugs to targeted ocular tissues. 
 Under the terms of the agreement, Ocular Therapeutix and Regeneron will aim to develop a
sustained release formulation of aflibercept that is suitable for advancement into clinical development. Regeneron has the option to obtain an exclusive license to use Ocular Therapeutix’s hydrogel-based technology for the development and
commercialization of a sustained release formulation of aflibercept and other biologies targeting VEGF for ophthalmic indications. Ocular Therapeutix will retain all rights to develop its sustained-release hydrogel-based drug delivery platform
with all other non-VEGF targeting compounds as well as with small molecule pharmaceuticals, including TKIs, for other retinal diseases. 
 Upon exercising
of the option, Ocular Therapeutix would receive a payment of $10 million from Regeneron and Ocular Therapeutix would be responsible for funding development through Phase 1. Regeneron would be responsible for any subsequent development and
commercialization costs. Ocular Therapeutix would be eligible to receive up to $305 million in milestone payments from Regeneron for a sustained release version of aflibercept containing Ocular Therapeutix’s sustained release hydrogel
depot, comprised of up to $155 million in development and regulatory milestone payments and up to $150 million in commercial milestone payments. In addition, Ocular Therapeutix is eligible to receive tiered high single-digit to low-to-mid
teen-digit royalties on potential future net sales. 

 “We have made considerable progress in developing our protein drug delivery platform at Ocular Therapeutix,
so it is good to see an industry leader such as Regeneron recognizing the potential of this technology,” said Amar Sawhney, Ph.D., President, Chief Executive Officer and Chairman of Ocular Therapeutix. “We are excited to partner with
Regeneron to develop a potential first-in-class sustained release protein-based anti-VEGF hydrogel injection for wet AMD, DME, RVO, and other serious retinal diseases. This sustained release formulation could have the potential to significantly
reduce dosing frequency and subsequently reduce doctor visits, thus reducing the burden of care for patients, caregivers and physicians, and may decrease the likelihood of certain side effects associated with frequent intravitreal injections.”

 About Wet AMD and Other VEGF-Associated Retinal Diseases 

Wet age-related macular degeneration (wet AMD) is characterized by loss of vision caused by degeneration of the central portion of the retina. Abnormal
growth of blood vessels below the retina, and the leakage of fluid and protein from the vessels, causes retinal degeneration and can lead to severe and rapid loss of vision. Wet AMD is the leading cause of blindness in individuals aged 50 years
or older. 
 Retinal vein occlusion (RVO) is a sight-threatening disorder resulting from the blockage of one of the veins carrying blood out of the
retina. In RVO, the blockage of a retinal vein can lead to poor blood circulation, low oxygen and sometimes inflammation in the eye. A blocked vein will leak its contents of blood and fluid. Bleeding within the retina and swelling
from the fluid can result in macular edema. 
 Diabetic macular edema (DME) is a complication of diabetes caused by fluid accumulation in the macula, or
central portion of the eye. When the macula begins to fill with fluid, the ability of those cells to sense light is impaired, causing blurred vision that can be severe. Diabetic macular edema affects up to 30% of people who have had
diabetes for 20 years or more, and if untreated, 20 to 30% of people who have it will experience moderate visual loss. 
 The global market for anti-VEGF
drugs is over $7.5 billion.
