Cara hereby agrees that (a) it shall not use or practice the Licensed Technology for any purpose other than exercising its rights and performing its obligations under this Agreement; and (b) except for the rights expressly set forth in this Agreement, Cara is not granted any rights, title or interest in or to such Licensed Technology.

2.7 Negative Covenant. In order to preserve the economic value of the business deal in this Agreement for each Party, Enteris covenants that during the Term, it and its Affiliates shall not grant any third party generic manufacturer of pharmaceutical or drug products any license

or other rights (such as a covenant not to sue) under the Licensed Technology to Develop, Manufacture, or Commercialize any drug products containing the Drug in the Territory for use in the Field; provided that, the foregoing covenant shall automatically terminate, and this Section 2.7 shall thereafter be of no force and effect, if none of Cara or its Affiliates or Sub-licensees have launched a commercial Product by [***].

ARTICLE 3

DEVELOPMENT, REGULATORY AND COMMERCIALIZATION

3.1 Manufacture by Enteris. Enteris shall continue to perform its obligations under the Manufacturing Services Agreement in accordance with the terms thereof, including manufacture and supply requirements for Drug products for ongoing and (if applicable) future Phase 1 and Phase 2 clinical trials, until termination of such agreement. For clarity, the first sentence of Section 2.5 and the first sentence of Section 4.1(b) of the Manufacturing Services Agreement are hereby terminated.

3.2 Technology Transfer by Enteris.

(a) Enteris acknowledges that the transfer of all Licensed Technology existing as the Effective Date is critical to Cara’s ability to exercise its rights and receive its benefits under this Agreement. Enteris hereby covenants that it shall complete the transfer of all such Licensed Technology, subject, however, to the cooperation, resources and efforts of Cara's CMO to fully and effectively receive such technology transfer, commencing on a date as reasonably specified by Cara, and Enteris shall use diligent, good faith efforts to complete such technology transfer, including achieving the Completion of Analytical Procedures Transfer and Completion of Manufacturing Processes Transfer, as soon as reasonably practicable thereafter. Cara shall cause its CMO to use diligent, good faith efforts to accept the technology transfer, and the Parties shall (and Cara shall cause its CMO to) work collaboratively and in good faith to conduct the full, accurate, and complete technology transfer under the Project Plan through the Completion of Analytical Procedures Transfer and Completion of Manufacturing Process Transfer.

(b) The Parties agree that the fee for the work as set forth under Section I of the Project Plan as of the Effective Date (Completion of Analytical Procedures Transfer) is [***]. Prior to commencement of the transfer of the manufacturing process, fees for all work contemplated under Section II of the Project Plan (Transfer of Manufacturing Process) shall be proposed by Enteris and agreed to by Cara, and such fees shall be commercially reasonable and typical for similar technology transfer work. In the event that Cara reasonably determines that additional technology transfer work by Enteris – beyond the tasks generally set forth in the then-current Project Plan – are needed to enable the CMO successfully to complete manufacture of amounts of Product as specified in and in accordance with the criteria in Section II (Transfer of Manufacturing Process) of the Project Plan to achieve Completion of Manufacturing Process Transfer, then the Parties shall discuss and agree reasonably and in good faith on such additional work required to be conducted by the Parties (and, if applicable, any CMO selected by Cara) to satisfy all the

acceptance criteria in the Project Plan, and a timeline and budget for such work (with the Enteris fees for such additional Enteris work to be commercially reasonable and typical for similar technology transfer work), in each case in accordance with Section 3.2(c). Notwithstanding the foregoing, any additional work performed by Enteris in furtherance of the analytical procedures transfer under Section I of the initial Project Plan, but not set forth in Section I of the Project Plan as of the Effective Date, shall not be included in the [***] fee, and the fee for such additional work shall be commercially reasonable and typical for similar technology transfer work. All payments due under this Section 3.2 shall be paid upon Completion of the Analytical Procedures Transfer or Completion of the Manufacturing Process Transfer, as applicable.

(c) Cara shall request additional services to the Project Plan in writing, detailing the proposed changes to the services (“Change of Scope”). Within [***] of Enteris’ receipt of such proposed Change of Scope, Enteris shall provide Cara with a cost and time estimate for performing the additional services as proposed, and the fees for such work, which costs and fees shall be commercially reasonable and typical for similar work. The Parties shall jointly review and discuss the proposed Change of Scope, costs, fees and time estimate reasonably and in good faith. Such additional services shall become part of the Project Plan upon execution by both Parties of the Change of Scope. Any disagreements with respect to the Change of Scope shall be subject to Section 11.1.

(d) For purposes of this Section 3.2, Cara shall ensure that any CMO of Cara is subject to confidentiality provisions comparable in scope to Article 4 with respect to the transfer by Enteris to Cara and its CMO of information and Know-how under Section 3.2. Enteris does not represent or warrant that the use of, or results from, the analytical procedures or manufacturing processes will satisfy the requirements of any Regulatory Authority at the time of submissions of any Regulatory Filings to any such Regulatory Authority.

3.3 Cara’s Rights and Obligations.

(a) Except as provided in Section 3.1, Cara shall have the sole right and responsibility, at its sole cost and expense, and in its sole discretion, for the Development, Manufacture and Commercialization of Products for use in the Field and in the Territory.

(b) Cara shall have the sole right and responsibility, at its sole cost and expense, and in its sole discretion, during the Term to Develop, seek Regulatory Approval, and (if Regulatory Approval is achieved) Commercialize Products in the Field in the Territory and shall, in its sole discretion, commit such resources (including employees, consultants, contractors, facilities, funding, equipment and materials) as it determines are necessary or appropriate to conduct such Development and Commercialization activities.

(c) Cara shall provide Enteris with written reports describing in reasonable summary its Development activities and Commercialization activities with respect to the Products in the Territory and the results of such activities on an annual basis, with the first report being due [***] after the Effective Date, which reports shall include a reasonable

summary of: (a) all Development and Commercialization activities conducted with respect to the Product (including the status of any clinical trials) and any launch plans (including expected date of first commercial sales of Product); (b) the Regulatory Filings with respect to such Products that Cara or any of its Affiliates have filed, sought or obtained in the prior [***] period or reasonably expect to make, seek or attempt to obtain in the following [***] period in the Territory, and (c) any Significant Development Events applicable to the Product. The reports shall also include a summary of all material questions asked by any Regulatory Authority to Cara regarding the Licensed Technology and of Cara’s responses thereto. For purposes of clarity, the obligation to provide summary reports hereunder does not affect or supersede any such reporting or disclosure obligations of Cara as set forth in the Manufacturing Services Agreement.

3.4 Regulatory Responsibility. Cara (and including its Affiliates and Sub-licensees) shall have the sole right and responsibility, at its and their sole discretion for (a) preparing, filing and maintaining all Regulatory Filings for Products in its own name in the Territory; provided that Enteris shall prepare, file and solely and exclusively own the Enteris DMF and all contents therein, and Cara shall have no ownership interest whatsoever in the Enteris DMF or the contents therein, and (b) reporting to Regulatory Authorities all adverse events and serious adverse events occurring in any clinical trials conducted by Cara related to any Products, to the extent required by Applicable Laws. Enteris agrees to provide Cara with all information contained in the Enteris DMF, and in any analogous regulatory filing or documents in any other jurisdiction, to facilitate Cara’s Regulatory Filings in jurisdictions where the Enteris DMF is not recognized, subject to Section 4.8, it being understood that such information is deemed Proprietary Materials of Enteris.

3.5 Recalls. If any Regulatory Authority issues or requests a recall or takes similar action in connection with any Product in the Territory, or if Cara (or and its Affiliate or Sub-Licensee) reasonably believes that an event, incident or circumstance has occurred that may result in the need for a recall, market withdrawal or other corrective action regarding the Product, Cara shall promptly advise Enteris thereof by telephone or facsimile. Following such notification, Cara (or and its Affiliate or Sub-Licensee) shall decide and have control of whether to conduct a recall or market withdrawal (except in the event of a recall or market withdrawal mandated by a Regulatory Authority, in which case it shall be required) or to take other corrective action in any country and the manner in which any such recall, market withdrawal or corrective action shall be conducted; provided, that, Cara shall keep Enteris regularly informed regarding any such recall, market withdrawal or corrective action. All expenses incurred by Cara in connection with any such recall, market withdrawal or corrective action (including, without limitation, expenses for notification, destruction and return of the affected Product and any refund to customers of amounts paid for such Product) shall be the sole responsibility of Cara.

3.6 Safety Information. Each Party shall disclose to other Party any and all information of which that Party (or its Affiliate) becomes aware relating to any safety issues for formulations using or based on the Licensed Technology, which reasonably may impact the safety of Product, such disclosure to be made promptly after the Party becomes aware thereof.

3.7 Reference Rights. Cara (and its Affiliates and Sub-Licensees) shall have (i) the right of reference to the Enteris DMF and the information therein, and (ii) the right to reference the information contained in the Enteris DMF in all of Cara’s (and its Affiliates and Sub-Licensees) Regulatory Filings in jurisdictions where the Enteris DMF is not recognized, in each case solely for the purpose of exercising, using and practicing the licenses and other rights granted to Cara pursuant to this Agreement, provided that Cara shall bear any expenses (including expenses of Enteris) in respect of exercising any such right of reference.

ARTICLE 4

(c) such disclosure is reasonably necessary to any bona fide potential or actual investor, acquiror, merger partner or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that, in each case, the disclosees are bound by written obligations of confidentiality and non-use no less stringent than to those of this Agreement with a reasonable duration based on customary terms, and further provided that in the case of any such disclosure of Confidential Information to any actual or potential competitor of either Party, all competitively sensitive information (including, for the avoidance of doubt, all financial information) herein shall be redacted until, subject to Applicable Laws, the execution of a definitive agreement with such actual or potential competitor to implement a transaction with the receiving Party is imminent; or

(d) such disclosure is reasonably necessary to comply with Applicable Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or other order.

(e) Notwithstanding the foregoing, if a Party or its Affiliate is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 4.2(a)(iii)-(iv) or 4.2(d), then such Party shall (i) promptly notify the other Party of such required disclosure, (ii) give the other Party an opportunity to seek confidential treatment and, upon the other Party’s request, such Party and its Affiliates shall use reasonable efforts to obtain,

or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure and (iii) if the other Party is unsuccessful in its efforts pursuant to subsection (ii), disclose only that portion of the Confidential Information that such Party is legally required to disclose.

4.3 Employees and Consultants. Enteris and Cara each hereby represents that all of its employees and consultants, and all of the employees and consultants of its Affiliates, who have access to Confidential Information of the other Party are or will, prior to having such access, be bound by written obligations to maintain such Confidential Information in confidence. Each Party agrees to use, and to cause its Affiliates to use, Commercially Reasonable Efforts to enforce such obligations and to prohibit its employees and consultants from using such information except as expressly permitted hereunder. Recipient party will be liable to the other for any disclosure or misuse by its employees of Confidential Information of the disclosing Party.

4.4 Publicity. The Parties shall, upon the execution of this Agreement, issue a joint press release with respect to this Agreement in a form mutually agreeable by both Parties, and each Party may make subsequent public disclosure of the contents of such press release without further approval of the other Party. After release of such press release, if either Party or its Affiliate desires to make a public announcement concerning the existence or terms of this Agreement, or any clinical or regulatory announcements, early notification of such public announcement by the proposing Party shall be given in writing to the other Party at least [***] before the proposed disclosure date and a draft of such public announcement shall be sent to the commenting Party for its review and comment at least [***] before the proposed disclosure date, but subject to Section 4.5. Under no circumstances shall any competitively sensitive information contained in this Agreement (including all financial information, including total value of this Agreement) be disclosed, except as otherwise provided in Section 4.5.

4.5 Public Filings. The Parties acknowledge that either or both Parties may be obligated to file under Applicable Laws a copy of this Agreement with the U.S. Securities and Exchange Commission or other Governmental Authorities. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of the commercial terms and sensitive technical terms hereof and thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party will provide the other Party with a copy of this Agreement marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s reasonable comments thereon to the extent consistent with the legal requirements, with respect to the filing Party, governing disclosure of material agreements and material information that must be publicly filed. Further, each Party acknowledges that the other Party, or its successor, may be required by Applicable Laws to make public disclosure of events or results of activities under this Agreement, and that such disclosures may be made, if required by such Applicable Laws, prior to the expiration of the notice periods in Section 4.4., provided that a Party (or successor) shall not, in any such public disclosure, disclose any of the other Party’s Confidential Information, unless such Party is required by Applicable Law to make such a public disclosure of such particular information. In such event, such Party shall submit the proposed disclosure in writing to the other Party as far in advance as reasonably practicable so as to provide a reasonable opportunity to comment thereon, and such Party required to make the disclosure shall consider all comments from such other Party

in good faith, and shall in any event only disclose such information of the other Party as is required by Applicable Law to be disclosed publicly in such manner.

4.6 Publications and Presentations. Except for disclosures permitted pursuant to Section 4.4 or Section 4.5, if a Party wishes to make a publication relating to activities conducted under this Agreement or the results of such activities hereunder, and such publication would disclose Confidential Information of the other Party, (a) it shall deliver to the other Party a copy of any such proposed written publication or an outline of a proposed oral disclosure at least [***] prior to submission for publication or presentation, (b) the reviewing Party shall have the right to require a delay of up to [***] in publication or presentation in order to enable patent applications to be filed protecting such reviewing Party’s rights in potentially patentable inventions that are owned by such Party and that would be publicly disclosed by the publication of the information in such publication, and (c) such reviewing Party shall have the right to prohibit disclosure of any of its Confidential Information in any such proposed publication or presentation. In any such publication or presentation by a Party, the other Party’s contribution shall be duly recognized, in accordance with customary industry standards. For clarity, Cara is free to make publications about its (and its Affiliates’ and Sub-licensees’) activities under this Agreement, and results of such activities, without review by Enteris, provided that such publications do not disclose Confidential Information of Enteris. Further, Enteris covenants that it and its Affiliates shall not publish (or permit publication of) any non-public information relating to Cara’s (and its Affiliate’s and Sub-licensee’s) activities under this Agreement, or the results of such activities, without the prior written consent of Cara, such consent not to be unreasonably withheld.

4.7 Permitted Publications. Notwithstanding Sections 4.4 through 4.6, either Party may include in a public disclosure or in a scientific or medical publication or representation, without prior delivery to or approval by the other Party, any information which has previously been included in a public disclosure or scientific or medical publication that has been approved or otherwise made pursuant to Section 4.4 or 4.5 or reviewed pursuant to Section 4.6 or published or publicly disclosed by the other Party. A Party relying on this Section 4.7 shall bear the burden of establishing that information has previously been included in a public disclosure or scientific or medical publication that has been approved pursuant to Section 4.4 or 4.5 or reviewed pursuant to Section 4.6 or published or publicly disclosed by the other Party. For clarity, Cara (and its Affiliates and Sub-licensees) retain the full rights to publish clinical and other data and results relating to Drug or Product without consent of or comment by Enteris, provided that such publications do not disclose Enteris Confidential Information. Cara and Enteris each may further disclose or publish that Cara and Enteris are parties to this Agreement and the general scope of the rights granted hereunder, but excluding any financial terms or the total value of the Agreement.

5.1 Enteris Rights. Enteris shall own all rights, title, and interest on a worldwide basis in and to the Licensed Patent Rights and Licensed Know-how, including any Improvements (including any Patent Rights claiming or covering such Improvements) regardless of inventorship, used to formulate, develop or otherwise exploit the Drug or Product, and Enteris retains all rights to prosecute and maintain the Licensed Patent Rights at its sole discretion and sole expense. Cara shall cooperate with and assist Enteris in all reasonable respects, at Enteris’ expense, in connection with Enteris’ preparation, filing, prosecution (including review and comments regarding responses to office actions and/or official actions from worldwide patent offices) and maintenance of such Licensed Patent Rights, including by obtaining assignments to reflect chain of title consistent with the terms of this Agreement, gaining United States patent term extensions, supplementary protection certificates and any other extensions that are now or become available in the future wherever applicable to such Licensed Patent Rights.

5.2 Cara Rights. Cara shall own all rights, title, and interest on a worldwide basis in and to any Inventions, other than Improvements, including any Patent Rights claiming or covering any such Invention, and Cara shall retain all rights to prosecute and maintain such Patent Rights in its sole discretion and sole expense. Further, and notwithstanding the foregoing, Cara shall own the overall formulation of the Product, provided that Enteris shall retain ownership of all Licensed Technology that claims or is incorporated in such formulation. Notwithstanding the foregoing, Cara acknowledges that a license shall be required with respect to any formulation to the extent that the formulation uses or practices issued patents or Confidential Information of Enteris in the Licensed Technology (excluding any Confidential Information that is subject to any of the exceptions in subsections 4.1(a)-(e)).

5.3 Notice; Inventorship. Cara hereby agrees to promptly notify Enteris of the conception or reduction to practice of any Improvements made by or on behalf of Cara and to promptly execute any documents that may be necessary to perfect Enteris’ ownership and rights in and to any such Improvements. In case of a dispute between the Parties over whether any particular Invention is an Improvement, such dispute shall be resolved according to U.S. patent law pursuant to Article 11, with an arbitration (if conducted) by patent counsel mutually selected by the Parties who (and whose firm) is not at the time of the Dispute, and was not at any time during the [***] prior to such Dispute, performing services for either of the Parties. Expenses of the patent counsel shall be shared equally by the Parties. With respect to any Inventions that are Improvements, Cara, its Affiliates and Sub-licensees, and their respective employees,

subcontractors and contractors, and agents, shall assign, and do hereby irrevocably and perpetually assign, to Enteris, all worldwide rights, title and interest in and to all such Improvements (including all Patent Rights or other intellectual property rights relating thereto).

5.4 Third Party Infringement.

(a) Notice. If either Party becomes aware of any suspected infringement or misappropriation of any Licensed Technology that cover the Development, Manufacture or Commercialization of the Product anywhere in the Territory (each, an “Infringement”), that Party shall promptly notify the other Party within [***] and provide it with all details of such Infringement of which it is aware, excluding privileged information (each, an “Infringement Notice”).

(b) Enteris Right to Enforce. Enteris shall have the first right, but not the obligation, to address such Infringement in the Territory that involves such Licensed Technology by taking reasonable steps, which may include the institution of legal proceedings or other action, and to compromise or settle such Infringement (each, an “Infringement Response”); provided, that: (A) Enteris shall keep Cara fully informed about such Infringement Response and Cara shall provide, at Enteris’ expense all reasonable cooperation to Enteris in connection with such Infringement Response; (B) Enteris shall not take any position with respect to, or compromise or settle, any such Infringement in any way that is reasonably likely to directly and adversely affect the scope, validity or enforceability of any such Licensed Technology, without the prior consent of Cara, which consent shall not be unreasonably withheld, conditioned or delayed; and (C) if Enteris does not intend to prosecute or defend an Infringement, or ceases to diligently pursue an Infringement Response with respect to such an Infringement, it shall inform Cara in such a manner that such Infringement Response will not be prejudiced and Section 5.4(c) shall apply. [***]

(c) Cara’s Right to Enforce. If (A) Enteris informs Cara in writing that it does not intend to prosecute any Infringement Response with respect to any such Infringement, (B) within [***] after the receipt of notice of any such Infringement, Enteris has not commenced to take any Infringement Response with respect thereto, or (C) if Enteris does not diligently pursue any such Infringement Response, then, unless Enteris provides Cara with a commercially reasonable justification for its delay of such Infringement Response, and provided that such delay will not adversely affect the scope, validity or enforceability of the Licensed Technology subject to the Infringement and will not materially affect Cara’s Commercialization of Product, Cara shall have the right, at its own expense, upon written notice to Enteris to take appropriate action to address such Infringement, including by initiating an Infringement Response or taking over prosecution of any legal proceedings initiated by Enteris. In that event, Cara shall keep Enteris fully informed about such Infringement Response and shall consult with Enteris before taking any major steps during the conduct of that Infringement Response. Enteris shall provide reasonable cooperation to Cara in connection with that Infringement Response. Cara shall not take any position with respect to, or compromise or settle, such Infringement in any way that is reasonably likely

to directly and adversely affect the scope, validity or enforceability of such Licensed Technology. [***]

(d) Right to Representation. Each Party shall have the right to participate and be represented by counsel that it selects, in any Infringement Response instituted under Section 5.4(b) or 5.4(c) by the other Party. If a Party with the right to initiate an Infringement Response under Section 5.4 to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such action, then the Party with the right to initiate an action under Section 5.4 may name the other Party as plaintiff in such action or may require the Party with standing to initiate such Infringement Response at the expense of the other Party.

(e) Cooperation. In any Infringement Response instituted under this Section 5.4, the Parties shall cooperate with and assist each other in all reasonable respects. Upon the reasonable request of the Party instituting that Infringement Response, the other Party shall join such Infringement Response and shall be represented using counsel of its own choice, at the requesting Party’s expense.

(f) Allocation of Recoveries. Any settlements, damages or monetary awards (“Recovery”) recovered by either Party pursuant to any Infringement Response shall, after reimbursing the Parties for their reasonable out-of-pocket expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses), [***].

5.5 Defense of Claims. If any action, suit or proceeding is brought against either Party or any Affiliate of either Party alleging the infringement of the Know-how or Patent Rights of a Third Party by reason of the Development, Manufacture or Commercialization of any Product, such Party shall notify the other Party within [***] of the earlier of (a) receipt of service of process in such action, suit or proceeding, or (b) the date such Party becomes aware that such action, suit or proceeding has been instituted, and the Parties shall meet as soon as possible to discuss the overall strategy for defense of such matter. Except as otherwise agreed in writing by the Parties, the Party alleged to have infringed, or whose Affiliate or Sub-licensee is alleged to have infringed, shall have the obligation to defend such action, suit or proceeding at its sole expense, and in its sole discretion; the other Party shall have the right to separate counsel at its own expense in any such action, suit or proceeding, provided that its intellectual property rights are actually at issue in the action or proceeding, and that it shall not interfere or compromise the defending Party’s defense of such action. In any such action or proceeding, the Parties shall cooperate with each other in all reasonable respects in the defense of any such action, suit or proceeding. All such expenses with respect to any such action, suit or proceeding in the Territory shall be borne solely by the Party defending such action, suit or proceeding. Each Party shall promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party including all material documents filed in any related litigations as to such infringement that are reasonably needed by the other Party, but excluding confidential or privileged communications or documents.

5.6 Patent Term Extension. The Parties shall cooperate with each other in obtaining patent term extensions or supplemental protection certificates or their equivalents in any country in the Territory where applicable to Licensed Patent Rights. Such cooperation shall include diligently and timely conferring and coordinating with respect to such matters to ensure compliance with applicable filing deadlines, and agreeing on procedures to be followed by the Parties to ensure such compliance. In the event that elections with respect to obtaining such patent term extension are to be made, Enteris shall have the right to make the election with respect to Licensed Patent Rights.

5.7 Patent Marking. Cara agrees to mark, and to cause its Affiliates and Sub-licensees to mark, Products sold in the U.S. with all applicable U.S. patent numbers in issued Patent Rights that claim the Product (or its manufacture), and to mark Products shipped to or sold in other countries, in each case to comply with the patent laws and practices of the countries of manufacture, use and sale. Such marking may be on the packaging for the Products, if permitted by Applicable Laws.

For sales of Product in countries where there is no valid claim in an issued patent in the Licensed Patent Rights that covers the Product, royalties for such Product in such country will be paid on Net Sales of such Product in such country at [***] of the royalty rate otherwise applicable to such Net Sales in the above schedule.

(i) On or before the first (1st) anniversary of the Effective Date, Cara shall have the right, but not the obligation, to terminate its obligation to pay any royalties by paying to Enteris or Enteris’ designees (as contemplated by the Stock Purchase Agreement) the sum of [***] payable in cash (the “One Year Royalty Buyout”).

(ii) After the first (1st) anniversary of the Effective Date but on or before the second (2nd) anniversary of the Effective Date, Cara shall have the right, but not the obligation, to terminate its obligation to pay any royalties by paying to Enteris or Enteris’ designees (as contemplated by the Stock Purchase Agreement) the sum of [***] payable in cash (the “Two Year Royalty Buyout”, collectively with the One Year Royalty Buyout, the “Royalty Buyouts”, and each a “Royalty Buyout”).

(iii) If either (x) Cara is a “well-known seasoned issuer,” as such term is defined in Rule 405 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), as of the date of the exercise of the Royalty Buyout, or (y) (i) the staff of the Division of Corporation Finance of the U.S. Securities and Exchange Commission has issued to Cara a no-action letter regarding the commencement of the holding period under Rule 144(d) promulgated under the Securities Act for such shares of Cara stock as are otherwise issuable at the election of Cara as partial payment of the Royalty Buyout as permitted under this Section 6.5(c)(iii), and such no-action letter permits tacking of such holding period back to the date of this Agreement, and (ii) sufficient time has passed since the date of this Agreement (and all other requirements under Rule 144 are met) to permit the holders of the stock to be issued by Cara in relation to the Royalty Buyout to sell all such shares on the date of Cara’s exercise of such option in compliance with Rule 144 under the Securities Act without any restrictions, then Cara shall have the option, but not the

obligation, to pay fifty percent (50%) of the Royalty Buyout amount by issuing Cara stock to Enteris or its designee pursuant to the Stock Purchase Agreement.

(iv) In order to exercise a Royalty Buyout, Cara shall notify Enteris and, if the option to partially pay in Cara stock as permitted by Section 6.5(c)(iii) above is exercised by Cara, EBP Holdco LLC and any designees of Enteris and EBP Holdco LLC, in writing that it is paying the Royalty Buyout and shall pay such Royalty Buyout within [***] of such notice. For avoidance of doubt, upon Enteris’ receipt of the Royalty Buyout under this Section 6.5(c), no royalties shall thereafter be due to Enteris under this Agreement and the Royalty Term (and the provisions of this Section 6.5) shall end immediately. For the avoidance of doubt, the expiration of the Royalty Term, including due to payment of a Royalty Buyout, shall not affect Cara’s obligation to pay Enteris milestones pursuant to Section 6.2 of this Agreement, including milestone events based on [***]. In the event that Cara provides Enteris with a notice that it is exercising the Royalty Buyout but no payment is received by Enteris within the [***] period (other than solely due to an issue with Enteris or its bank), then the Royalty Buyout is deemed to not have been exercised. Such failure to pay the Royalty Buyout amount within that [***] period is not subject to cure.

6.6 Payment Dates and Reports. Cara shall make all royalty payments due hereunder within [***] after the end of each Calendar Quarter in which the sale of such Product shall occur. Cara shall provide, within [***] after each Calendar Quarter in which a sale of such Product shall occur, a report showing: (a) the Net Sales of each Product by type of Product and country in the Territory; (b) an itemization of the deductions permitted to determine Net Sales; (c) a calculation of the amount of royalty due to Enteris, if applicable; and (d) [***]. Payment of all milestone events due hereunder, including the milestones on [***], shall be made in accordance with Section 6.2. The Parties agree that, notwithstanding anything to the contrary in the Manufacturing Services Agreement, Cara has and shall have no further obligation under Section 4.1(b) of the Services Agreement to pay any additional License Access Fees (as defined in the Manufacturing Services Agreement), and any such obligation going forward is hereby terminated.

6.7 Records; Audit Rights. Cara and its Affiliates and Sub-licensees shall keep and maintain, for [***] from the date of (x) each payment of royalties under this Agreement and (y) each milestone owed, complete and accurate records of gross sales and Net Sales by Cara and its Affiliates and Sub-licensees, in sufficient detail to allow royalties and milestones on Net Sales to be determined accurately. All such records required to be maintained under this Section 6.7 shall include the information contained in the reports required under Section 6.6. Enteris shall have the right for a period of [***] after receiving any such payments to appoint at its expense an independent certified public accountant reasonably acceptable to Cara to audit such records of Cara, or its Affiliates, to verify that the amount of any such payment was correctly determined. Cara and its Affiliates shall each make its records available for audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon [***] written notice from Enteris. Such audit right shall not be exercised by Enteris more than once in any Calendar Year or more than once with respect to sales of a particular Product in a particular period or with respect to an individual milestone. All records

made available for audit shall be deemed to be Confidential Information of Cara. The results of each audit, if any, shall be binding on both Parties absent manifest error. In the event there was an underpayment by Cara under this Agreement, Cara shall promptly (but in any event no later than [***] after Cara’s receipt of the report so concluding) make payment to Enteris of any shortfall together with interest as provided in Section 6.8 from the date such payment was due to the date paid in full. Enteris shall bear the full cost of such audit unless such audit discloses a variance to the detriment of Enteris of five percent 5% or more from the amount of the original payment calculation in which case Cara shall bear all reasonable cost of the performance of such audit.

6.8 Overdue Payments. All payments not made by Cara to Enteris when due under this Agreement shall bear interest at a rate equal at [***] (as quoted in The Wall Street Journal or its successor on the day after the payment is due) calculated from the due date to the date paid in full. Any such overdue payment shall, when made, be accompanied by, and credited first to, all interest so accrued.

6.9 Payments; Withholding Tax.

(a) Payments in Dollars. All payments made by Cara under this Section shall be made by wire transfer from a banking institution in United States Dollars in accordance with instructions given in writing from time to time by the other Party.

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

6.10 Foreign Currency Exchange. If, in any Calendar Quarter, Net Sales are made in any currency other than United States Dollars, such Net Sales shall be converted into United States Dollars by applying the exchange rate conversion consistently used by Cara in its audited consolidated accounts making use of a publicly available foreign exchange rate source.

6.11 Cara Obligations. Cara shall be solely responsible for all amounts it owes to any Third Party in connection with the Development, Manufacture, or Commercialization of Products in the Field in the Territory.

Provided that the Indemnifying Party is not contesting its obligation to indemnify as to the noticed Claim under this Article 7, the Indemnified Party (and the Indemnified Member, as applicable) shall permit the Indemnifying Party to control any the defense of such Claim and any litigation relating to such Claim and all related Losses and the disposition of such Claim and Losses.

DISPUTE RESOLUTION; ARBITRATION

11.1 Dispute Resolution. If a dispute or issues arises between the Parties regarding any matter under this Agreement, including interpretation of a provision of the Agreement or performance or breach of an obligation hereunder, (a “Dispute”) then on notice from either Party detailing such Dispute, the senior executive officers of each Party shall promptly meet and discuss and seek to resolve, reasonably and in good faith, such Dispute, for a period of up to [***] from the date of receipt of such notice. Any resolution by the Parties of such a Dispute shall be set forth in writing acknowledged by the Parties. Neither Party shall initiate any court or other legal proceeding to resolve or enforce its rights as to, any Dispute except as provide in this Article 11.

11.2 Arbitration of Unresolved Disputes. For any Dispute that is not resolved by the Parties pursuant to Section 11.1 above, such Dispute shall be resolved, at the election of either Party, by binding arbitration before a panel of three (3) neutral, fully independent arbitrators in accordance with the rules of the American Arbitration Association (“AAA”) in effect at the time the proceeding is initiated, by such Party providing written notice of the arbitration, such notice setting forth in detail the Dispute to be resolved. In any such arbitration, the following procedures shall apply:

(a) The panel will be comprised of one arbitrator chosen by Cara, one by Enteris and the third, who shall act as the chairman of the panel, by the two co-arbitrators. If either Party fails or both Parties fail to choose an arbitrator or arbitrators within [***] after receiving notice of commencement of arbitration or if the two arbitrators fail to choose a third arbitrator within [***] after their appointment, then either or both Parties shall immediately request that the AAA select the remaining number of arbitrators to be selected, which arbitrator(s) shall have the requisite scientific background, experience and expertise. All such arbitrators must have no current or prior relationship with or to either Party and all its respective Affiliates, be neutral and unbiased as to the subject matter of the Dispute, and have significant experience in the creation and interpretation of license agreements similar to this Agreement. The place of arbitration shall be New York, New York. The language of the arbitration shall be English.

(b) Either Party may apply to the arbitrators for interim injunctive relief until the arbitration decision is rendered or the Dispute is otherwise resolved. Either Party also may, without waiving any right or remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending resolution of the Dispute pursuant to this Section 11.2. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages.

(c) The award of the arbitrators shall be final and binding on the parties (except for those remedies expressly set forth in this Agreement). Judgment on the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. Notwithstanding anything in this Section 11.2 to the contrary, each Party shall have the right to institute judicial proceedings against the other Party or anyone acting by, through or under such other Party, in order to enforce the instituting Party’s rights hereunder through specific performance, injunction or similar equitable relief.

(d) Each Party shall bear its own costs and expenses and attorneys’ fees in connection with any such arbitration; provided, that, the arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to the prevailing Party reimbursement for its reasonable attorneys’ fees, costs and expenses (including, for example, expert witness fees and expenses, photocopy charges and travel expenses).

(e) Unless otherwise agreed by the parties, Disputes relating to patents and non-disclosure, non-use and maintenance of Confidential Information shall not be subject to arbitration, and shall be submitted to a court of competent jurisdiction.

(f) The arbitration shall be confidential. Except to the extent necessary to confirm an award or decision or as may be required by Applicable Laws, neither Party nor any arbitrator may disclose the existence or results of any arbitration without the prior written consent of both parties.

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

12.9 Delay Due to Force Majeure. A Party shall not be liable for failure of or delay in performing any of its obligations set forth in this Agreement, and shall not be deemed in breach of such obligations, if such failure or delay is due to a Force Majeure. In the event of such Force Majeure, the Party affected shall use Commercially Reasonable Efforts to cure or overcome the same and resume performance of its obligations hereunder. Notice of a Party’s failure or delay in performance due to Force Majeure must be given to the other Party within thirty (30) days after the affected Party becomes aware of its occurrence. All delivery dates under this Agreement that have been affected by Force Majeure shall be tolled for the duration of such Force Majeure. If a Force Majeure persists for more than ninety (90) days, then the Parties will discuss in good faith the reasonable modification of the Parties’ respective obligations under this Agreement in order to mitigate the delays caused by such Force Majeure and the impacts of such delays.
