Trevena shall: (a) use Commercially Reasonable Efforts to conduct the Development Program, at its sole cost and expense, under the oversight of the JDC, in accordance with the Initial Development Plan (including the timelines set forth therein); and (b) conduct the Development Program in good scientific manner and in compliance, in all material respects, with all Applicable Law. Without limiting the foregoing, Trevena shall comply with its Sponsor Responsibilities in connection with the Trevena Study and nothing in this Agreement shall be construed to prohibit any such compliance.

2.2.2. Trevena shall consider in good faith any reasonable request by Forest that Forest or one of its Affiliates perform specified activities with respect to the Development Program. The performance of any such activities by Forest or its Affiliate would be subject to a separate agreement between Trevena and Forest (or its applicable Affiliate) governing the terms and conditions under which Forest or its Affiliate would perform such activities.

2.2.3. If, in Forests good faith belief, Trevena is performing the Development Program in a manner that could reasonably be expected to adversely and materially impact: (a) the timelines for the Trevena Study set forth in the Initial Development Plan; (b) the likelihood of the Trevena Study [*] as set forth in the then-current Initial Development Plan; (c) Trevenas compliance with any Applicable Law; or (d) the [*] with respect to the Development Program, Forest may raise any such concerns through the JDC or to Trevena directly. If Trevena fails to take appropriate steps to remedy such concern within [*] days of Forest first raising such concern to the JDC or Trevena, as applicable, or such shorter period of time as is necessary to [*] in the [*] or to [*] with any [*], then Forest shall have the right, at Forests sole election, and without limitation to any other right or remedy available to Forest, to assume and complete some or all of the applicable activities with respect to the Development Program by notifying Trevena in writing of such election within [*] days after the end of such [*]-day (or shorter, if applicable) period (any such assumed activities specified by Forest in its notice to Trevena, the Assumed Development Program Activities). For clarity, Forests election to assume and complete the Assumed Development Program Activities shall not change the [*] or alter the [*] of [*] or [*]

hereunder, except that Forest shall provide Trevena any data or Information generated in connection with the Assumed Development Program Activities that is necessary for Trevena to be able to deliver the complete Development Data Package and to the extent that Forest does not provide such data or Information to Trevena in sufficient time for Trevena to include such data or Information in the Development Data Package, Trevena shall be relieved from its obligation to include such data or Information in the Development Data Package.

2.2.4. If Forest so elects to assume and complete any Assumed Development Program Activities pursuant to Section 2.2.3 then:

(a) Trevena shall, and hereby does effective as of the date of such election, grant Forest a semi-exclusive (with Trevena and its Affiliates), royalty-free (i) license under the Trevena Patents and Trevena Know-How and (ii) license and right of reference under the Trevena Regulatory Documentation, in each case ((i) and (ii)), to perform the Assumed Development Program Activities;

(b) to the extent requested by Forest in writing and where necessary or reasonably useful to conduct the Assumed Development Program Activities, (i) Trevena shall assign to Forest any or all of its agreements with Third Parties pertaining to the Assumed Development Program Activities (including agreements with contract research organizations, clinical sites and investigators) and (ii) to the extent the terms of any such agreement prohibit Trevena from assigning it to Forest, or if any agreement with a Third Party that pertains to the Assumed Development Program Activities also pertains to other activities, in either case, Trevena shall use Commercially Reasonable Efforts to obtain for Forest the benefit under such agreement with respect to the Assumed Development Program Activities;

(c) with respect to any Assumed Development Program Activities that involve control of human clinical trials, Trevena shall transfer to Forest or its designee the appropriate Sponsor Responsibilities for such clinical trials and cooperate with Forest to ensure a smooth and orderly transition thereof that will not involve any disruption of such clinical trials;

(d) Trevena shall [*] and [*] in connection with the assumption and completion of the Assumed Development Program Activities [*] from Forest setting forth in [*] and [*] in connection with the assumption and completion of the Assumed Development Program Activities; provided, however, that in no event shall Trevena be required to [*] with respect to the Assumed Development Program Activities [*] set forth in the Initial Development Plan with respect to the corresponding Assumed Development Program Activities;

(e) Forest shall use Commercially Reasonable Efforts to conduct such Assumed Development Program Activities in accordance with the Initial Development Plan and the timelines therein and under the oversight of the JDC and in good scientific manner and in compliance, in all material respects, with all Applicable Laws. For clarity, any changes to the Initial Development Plan, including any additions to the activities therein, shall be subject to approval by the JDC as set forth in Section 3.1, subject to the

decision-making procedures set forth in Section 2.1.4, Section 2.1.5, Section 3.3 or Section 3.4, if applicable; and

(f) Section 2.5 and Section 2.7 shall apply to Forest with respect to such Assumed Development Program Activities, mutatis mutandis.

2.3. Delivery of Development Data Package.

2.3.1. Trevena shall, or shall cause any applicable Third Party to, grant Forest reasonable electronic access to the interim raw data generated or compiled in connection with the [*] as soon as such data is available to Trevena.

2.3.2. Within [*] days after the completion of the Interim Analyses, the Parties, through the JDC, shall discuss in good faith and agree on any changes to the then-current Development Plan Analyses based on such Interim Analyses.

2.3.3. Within [*] days after the adoption by the JDC of the final Development Plan Analyses pursuant to Section 2.3.2, Trevena shall deliver to Forest mock-up tables, figures and listings for the Trevena Study based on the then-current Development Plan Analyses. Forest shall have [*] Business Days from date of delivery to review such mock-up tables, figures and listings and, to the extent it believes in good faith that an agreed analysis based on the Development Plan Analyses is missing from the mock-up tables, figures and listings, Forest shall have the right to request in writing that Trevena include such analysis in the final tables, figures and listings that are to be delivered as part of the Development Data Package and Trevena shall include any such analysis in the final tables, figures and listings that are in the Development Data Package.

2.3.4. Within [*] days following the database lock for the Trevena Study, Trevena shall deliver to Forest: (a) electronic copies of the final tables, figures and listings for the Trevena Study in scope and format as specified in the mock-up tables, figures and listings, amended as appropriate under Section 2.3.3; (b) a detailed summary of all data generated or compiled in connection with the Trevena Study; (c) electronic access to all raw data resulting from the Trevena Study; and (d) all results of the Development Plan Analyses, if any, not included in the final tables, figures and listings delivered under clause (a) (collectively, the information and access described in (a) through (d) referred to as the Development Data Package, and the date when delivery of all of the elements described in (a) through (d) has been made is the Data Package Delivery Date); provided that Trevena shall, or shall cause any applicable Third Party to, provide Forest the access referred to in clause (c) on an on-going basis as such data is available to Trevena.

2.3.5. Forest shall have [*] Business Days from the Data Package Delivery Date in which to review the Development Data Package, and, to the extent Forest believes in good faith that the final tables, figures and listings contained therein do not match the agreed mock-up tables, figures and listings or that there are missing analyses based on the agreed Development Plan Analyses or any other items required to be delivered by Trevena to Forest pursuant to Section 2.3.4, then Forest shall have the right to request in writing that Trevena

update the final tables, figures and listing to match the agreed mock-ups with respect thereto and include any such missing analyses, data or information and deliver a revised Development Data Package within [*] Business Days of the receipt of such request from Forest (the date of delivery of any such revised Development Data Package is referred to as the Revised Data Package Delivery Date, even if such date occurs after such [*]-Business Day period), and the Revised Data Package Delivery Date shall be the date from which the Option Exercise Period and the Renegotiation Option Period are measured. Should Forest fail to request any such revised Development Data Package within such [*]-Business Day period, such Development Data Package shall be deemed to be complete and final, and the Data Package Delivery Date shall be the date from which the Option Exercise Period and the Renegotiation Option Period are measured.

2.3.6. In addition, during the Option Exercise Period or the Renegotiation Option Period, as the case may be, Trevena promptly shall provide to Forest any additional Information related to Compounds or Products that Trevena or any of its Affiliates owns or controls as reasonably requested by Forest and that is necessary or reasonably useful for Forest to evaluate the Development Data Package or in order to make an informed decision regarding whether to exercise its License Option or Renegotiation Option. For clarity, any such additional Information shall be Information then in existence, the provision of which shall not require the conduct by Trevena of any additional Development activities or any additional analyses other than additional analyses that Forest is unable to conduct and that Trevena can reasonably conduct within [*] Business Days after Forests request with respect thereto. If Forest requests any such Information before the [*] day after the later of the Data Package Delivery Date and the Revised Data Package Delivery Date, if applicable, and Trevena does not provide Forest such Information within [*] Business Days after such request, then the Option Exercise Period and the Renegotiation Option Period shall each be extended by a period equal to the delay in Trevena providing such Information to Forest. If Forest requests any such Information on or after the [*] day after the later of the Data Package Delivery Date and the Revised Data Package Delivery Date, if applicable, but before the [*] day after the later of the Data Package Delivery Date and the Revised Data Package Delivery Date, if applicable, and Trevena does not provide Forest such Information within [*] Business Days after such request, then the Option Exercise Period shall be extended by a period equal to the delay in Trevena providing such Information to Forest.

2.3.7. The Development Data Package and any additional Information delivered pursuant to Section 2.3.6 shall be deemed Trevenas Confidential Information unless the License Agreement becomes effective pursuant to its terms, whereupon the Development Data Package shall be deemed Product Information (as defined in the License Agreement).

2.4. Option Backstop Date; ROFN.

2.4.1. If as of the Backstop Date the Trevena Study is not actively ongoing (other than due to a breach by Trevena of its obligations under Section 2.2.1) and has not been completed, the Option Exercise Period shall terminate as of the Backstop Date and

Forest shall have a right of exclusive negotiation as set forth in this Section 2.4. For clarity, this Section 2.4 will apply even if Forest is conducting Assumed Development Program Activities.

2.4.2. If Forest notifies Trevena within [*] Business Days after the Backstop Date that it is exercising its option under this Section 2.4 to engage in exclusive negotiations with Trevena with respect to negotiating the Revised Terms (such timely delivered notice, the Backstop Renegotiation Notice), then during the period beginning on the date Forest provides the Backstop Renegotiation Notice to Trevena and ending at 11:59 p.m. ET on the [*] day thereafter (such period, the Backstop Renegotiation Period), the Parties shall negotiate in good faith the Revised Terms. The Parties acknowledge and agree that the Revised Financial Terms [*] shall [*] financial terms set forth in the [*] that is [*] of the [*]. Except for the obligation to negotiate in good faith the Revised Terms under this Section 2.4.2, neither Trevena or Forest shall have any obligation with respect to the Revised Terms unless and until a definitive agreement setting forth the Revised Terms has been authorized by, and executed and delivered by an authorized officer of, each of the Parties.

2.4.3. If Forest delivers a Backstop Renegotiation Notice to Trevena within [*] Business Days after the Backstop Date and, despite good faith negotiations, Forest and Trevena do not agree on the Revised Terms during the Backstop Renegotiation Period, then, (a) subject to Section 9.3 and Section 9.4, this Agreement shall terminate as of the expiration of the Backstop Renegotiation Period and be of no further force and effect, (b) the License Agreement shall not become effective, and (c) Trevena shall be free to enter into any Third Party Agreement; provided, however, that [*] of the [*] shall [*] and [*], are [*] and [*] by [*], it being understood that a transaction described in Section 1.15.1 or Section 1.15.2 of the License Agreement shall not be subject to this Section 2.4.

2.4.4. Upon Forests reasonable request, Trevena shall provide Forest with a redacted copy of any such executed Third Party Agreement for Forest to verify Trevenas compliance with Section 2.4.3; provided, however, that Trevena may not redact any information that is reasonably necessary for Forest to verify such compliance. Notwithstanding the foregoing, in the event that the Third Party counterparty to such Third Party Agreement is unwilling to allow Trevena to provide a redacted copy of the Third Party Agreement to Forest, Trevena shall have the right to provide such Third Party Agreement to a Person selected by Forest who is not an Affiliate of Forest, or an employee of Forest, which such Person may review and evaluate such Third Party Agreement on Forests behalf and report to Forest its findings.

2.5. Development Program Records. Trevena shall maintain, or cause to be maintained, records of its scientific and clinical activities under the Development Program (the Development Program Records) in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes, which Development Program Records shall be complete and materially accurate and shall reflect all work done and results achieved in connection with the Development Program. Trevena shall ensure that the Development Program Records include only information with respect to the Development Program and do not include, and are not commingled with, records of activities outside of the Development Program. Trevena shall retain, or cause to be retained, the Development Program Records for at least [*] or

such longer period as may be required by Applicable Law. During the Option Exercise Period or the Renegotiation Option Period, as the case may be, upon Forests reasonable request, Trevena shall provide Forest reasonable access to the Development Program Records. The Development Program Records shall be deemed Trevenas Confidential Information unless and until the License Agreement becomes effective pursuant to its terms, whereupon the Development Program Records shall be deemed Product Information (as defined in the License Agreement).

2.6. Audit Rights. Forest, or its designee, shall have the right, at any time during the Term, but no more frequently than once every [*] months, during normal business hours and upon reasonable advance notice to Trevena of at least [*] days, to (a) visit Trevenas facilities used in the conduct of the Development Program or (b) review the Development Program Records, in either case ((a) or (b)) to verify Trevenas compliance with its obligations with respect to the Development Program under this Agreement; provided, however, that if Forest or its designee identifies any noncompliance by Trevena with its obligations with respect to the Development Program under this Agreement, then Forest or its designee shall have the right to conduct additional visits and reviews to determine whether Trevena has corrected any such noncompliance.

2.7. Development Report. At each JDC meeting, Trevenas members on the JDC shall provide a report to the JDC of its activities with respect to the Development Program conducted since the last JDC meeting, a reasonable summary of the results of such activities and the progress of the Development Program, which report is not required to be in writing. Between meetings of the JDC, at Forests reasonable request, Trevena shall provide Forest an update with respect to Trevenas activities with respect to the Development Program conducted since the last JDC meeting, including a reasonable summary of the results of such activities and the progress of the Development Program, which update is not required to be in writing.

2.9.1. On the Data Package Delivery Date, Trevena shall deliver to Forest a Schedule 9.2 to the License Agreement that is identical to Schedule 6.2.1 of this Agreement, except for any supplement or amendment to Schedule 6.2.1 of this Agreement with respect to any event, condition, fact or circumstance occurring after the Option Execution Date that, if existing or occurring prior to the Option Execution Date, would have been required to be set forth or described on Schedule 6.2.1 of this Agreement as of the Option Execution Date, or that is necessary to correct or modify any information on Schedule 6.2.1 that has been rendered inaccurate by an event, condition, fact or circumstance occurring after the Option Execution Date (the First Schedule 9.2).

2.9.2. Without limiting Section 2.9.1, on the Final Disclosure Date Trevena shall deliver to Forest either (a) a revised First Schedule 9.2 that, as of the Final

Disclosure Date, supplements or amends the First Schedule 9.2 with respect to any event, condition, fact or circumstance occurring after the Data Package Delivery Date (or if the Data Package Delivery Date has not occurred, the Option Execution Date), that, if existing or occurring prior to the Data Package Delivery Date (or the Option Execution Date, if applicable), would have been required to be set forth or described on the First Schedule 9.2 as of the Data Package Delivery Date (or the Option Execution Date, if applicable) or that is necessary to correct or modify any information on the First Schedule 9.2 that has been rendered inaccurate by an event, condition, fact or circumstance occurring after the Data Package Delivery Date (or if the Data Package Delivery Date has not occurred, the Option Execution Date) or (b) a written confirmation that Trevena has no further supplements or amendments to the First Schedule 9.2 (either (a) or (b), the Final Disclosure). Final Disclosure Date means the date that is the earlier of (x) the [*] Business Day prior to the expiration of the Option Exercise Period and (y) (i) if Forest delivers a License Option Intent Notice after the Data Package Delivery Date, the [*] Business Day after Forest delivers such License Option Intent Notice to Trevena and (ii) if Forest delivers a License Option Intent Notice before the Data Package Delivery Date, the [*] Business Day after Forest delivers such License Option Intent Notice to Trevena.

For clarity, an Updated Final Disclosure will not be valid if it is delivered after Forest delivers the License Option Exercise Notice to Trevena.

3.1. Joint Development Committee. Within 30 days after the Option Execution Date, the Parties shall establish a joint development committee (the Joint Development Committee or JDC), which shall consist of three representatives from each Party, each with the requisite experience to make decisions on behalf of the applicable Party with respect to the issues falling within the jurisdiction of the JDC. From time to time, each Party may substitute one or more of its representatives to the JDC on written notice to the other Party.

Each Party shall make all proposals for agenda items and shall provide all appropriate information with respect to such proposed items at least five Business Days in advance of the applicable JDC meeting; provided, however, that under exigent circumstances requiring input by the JDC, a Party may provide its agenda items to the other Party within a shorter period of time in advance of the applicable JDC meeting, or may propose that there not be a specific agenda for a particular JDC meeting, so long as the other Party consents to such later addition of such agenda items or the absence of a specific agenda for such JDC meeting (which consent shall not be unreasonably conditioned, withheld or delayed). The co-chairpersons of the JDC shall prepare and circulate for review and approval of the Parties minutes of each JDC meeting within 30 days after such JDC meeting. The Parties shall agree on the minutes of each JDC meeting promptly, but in no event later than the next JDC meeting.

Specific aspects or details of Confidential Information shall not be deemed to be within the public domain or in the possession of the receiving Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the receiving Party. Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the receiving Party unless the combination and its principles are in the public domain or in the possession of the receiving Party.

7.4. Public Announcements. The Parties have agreed upon the content of a joint press release that shall be issued substantially in the form attached hereto as Schedule 7.4, the release of which the Parties shall coordinate in order to accomplish such release promptly upon execution of this Agreement.

ARTICLE 8
INDEMNIFICATION

8.1. Indemnification Obligations.

8.1.1. Indemnification of Trevena. Trevena shall indemnify Forest, its Affiliates and its and their respective directors, officers, employees, and agents (the Forest Indemnitees), and defend and save each of them harmless, from and against any and all losses, damages, liabilities, costs, and expenses (including reasonable attorneys fees and expenses) (collectively, Losses) in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, Third Party Claims) to the extent arising or occurring as a result of Trevenas performance of the Development Program, except for those Losses for which Forest has an obligation to indemnify any Trevena Indemnitee pursuant to Section 8.1.2, as to which Losses each Party shall indemnify each of the Trevena Indemnitees or Forest Indemnitees, as applicable, to the extent of its respective liability for such Losses relative to the other Party.

8.1.2. Indemnification of Forest. Forest shall indemnify Trevena, its Affiliates and its and their respective directors, officers, employees, and agents (the Trevena Indemnitees), and defend and save each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims to the extent arising or occurring as a result of Forests performance of the Development Program, except for those Losses for which Trevena

has an obligation to indemnify any Forest Indemnitee pursuant to Section 8.1.1, as to which Losses each Party shall indemnify each of the Trevena Indemnitees or Forest Indemnitees, as applicable, to the extent of its respective liability for such Losses relative to the other Party.

8.2. Indemnification Procedures.

8.2.1. Notice of Claim. All indemnification claims in respect of a Forest Indemnitee or a Trevena Indemnitee shall be made solely by Forest or Trevena, as applicable (each of Forest or Trevena in such capacity, the Indemnified Party). The Indemnified Party shall give the Indemnifying Party prompt written notice (an Indemnification Claim Notice) within 15 Business Days of becoming aware of any Third Party Claim asserted or threatened against a Forest Indemnitee or a Trevena Indemnitee, as applicable, that could give rise to a right of indemnification under this Agreement, but in no event shall the Indemnifying Party be liable for any Losses to the extent such Losses result from any delay in providing such Indemnification Claim Notice. Each Indemnification Claim Notice must contain a description of the Third Party Claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party access to all papers and official documents received in respect of any Losses and Third Party Claims.

8.2.2. Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within 30 days after the Indemnifying Partys receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify any Forest Indemnitee or Trevena Indemnitee, as applicable, in respect of such Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against a Forest Indemnitees or Trevena Indemnitees, as applicable, claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of such Third Party Claim any legal counsel selected by the Indemnifying Party. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Forest Indemnitee or Trevena Indemnitee, as applicable, in connection with such Third Party Claim. If the Indemnifying Party assumes the defense of a Third Party Claim, except as provided in Section 8.2.3, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party or any Forest Indemnitee or Trevena Indemnitee, as applicable, in connection with the analysis, defense or settlement of such Third Party Claim. If it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or save harmless a Forest Indemnitee or Trevena Indemnitee, as applicable, from and against a Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including attorneys fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defense of such Third Party Claim.

8.2.3. Right to Participate in Defense. The Indemnified Party shall be entitled to participate in, but not control, the defense of a Third Party Claim and to employ

counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnified Partys sole cost and expense unless (a) the employment thereof has been specifically authorized by the Indemnifying Party in writing, (b) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 8.2.2 (in which case the Indemnified Party shall control the defense), or (c) the interests of the Indemnified Party and any Forest Indemnitee or Trevena Indemnitee, as applicable, on the one hand, and the Indemnifying Party, on the other hand, with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of all such Persons under Applicable Law, ethical rules or equitable principles (in which case the Indemnifying Party shall control its defense and the Indemnified Party shall control the defense of the Forest Indemnitees or the Trevena Indemnitees, as applicable). In any such event ((a), (b) or (c)), the Indemnifying Party shall reimburse the Indemnified Party (pursuant to Section 8.2.6) for any costs and expenses incurred in connection with such defense (including the cost of counsel).

8.2.4. Settlement. With respect to any Third Party Claim that the Indemnifying Party has assumed the defense of in accordance with Section 8.2.2 that relates solely to the payment of money damages in connection with such Third Party Claim that shall not result in any Forest Indemnitee or Trevena Indemnitee, as applicable, becoming subject to injunctive or other relief or otherwise adversely affecting the business of any Forest Indemnitee or Trevena Indemnitee, as applicable, in any manner, and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify all Forest Indemnitees or Trevena Indemnitees, as applicable, hereunder, the Indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Third Party Claim, on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate; provided, however, that the Indemnifying Party may not enter into any compromise or settlement unless such compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnified Party and all Forest Indemnitees or Trevena Indemnitees, as applicable, of a release from all liability in respect of such claim. With respect to all other Third Party Claims that the Indemnifying Party has assumed the defense of in accordance with Section 8.2.2, the Indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Third Party Claim; provided, however, that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably conditioned, withheld or delayed). If the Indemnifying Party has assumed the defense of a Third Party Claim in accordance with Section 8.2.2, the Indemnifying Party shall not be liable for any settlement or other disposition of such Third Party Claim by a Forest Indemnitee or a Trevena Indemnitee, as applicable, that is reached without the prior written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall not, and the Indemnified Party shall ensure that each Forest Indemnitee or Trevena Indemnitee, as applicable, does not, admit any liability with respect to or settle, compromise or discharge, any Third Party Claim for which it has or intends to seek indemnification under Section 8.1 without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably conditioned, withheld or delayed).

8.2.5. Cooperation. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall

cause each Forest Indemnitee or Trevena Indemnitee, as applicable, to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party and any Forest Indemnitee or Trevena Indemnitee, as applicable, of, records and information that are reasonably relevant to such Third Party Claim, and making all Forest Indemnitees or Trevena Indemnitees, as applicable, and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder; provided, however, that neither Party shall be required to disclose legally privileged information unless and until procedures reasonably acceptable to such Party are in place to protect such privilege, and the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable and verifiable out-of-pocket expenses in connection therewith.

8.2.6. Expenses. Except as specifically provided above, the costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim shall be reimbursed on a Calendar Quarter basis by the Indemnifying Party, without prejudice to the Indemnifying Partys right to contest any Forest Indemnitees or Trevena Indemnitees, as applicable, right to indemnification and subject to refund if the Indemnifying Party is ultimately held not to be obligated to indemnify a Forest Indemnitee or Trevena Indemnitee, as applicable.

8.3. Special, Indirect, and Other Losses. EXCEPT WITH RESPECT TO THE INTENTIONAL MISCONDUCT OR FRAUD OF A PARTY OR A PARTYS BREACH OF ITS OBLIGATIONS UNDER ARTICLE 7, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE ARISING FROM THIS AGREEMENT; PROVIDED, HOWEVER, THIS EXCLUSION IS NOT INTENDED TO, NOR SHALL, EXCLUDE ACTUAL OR COMPENSATORY DAMAGES OF THE AFFECTED PARTY, INCLUDING SPECIAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, OWED TO THIRD PARTIES AS A RESULT OF A THIRD PARTY CLAIM.

With respect to a permitted assignment to an Affiliate, the assigning Party shall remain responsible for the performance by such Affiliate of the rights and obligations hereunder. Neither Party may assign its rights and duties under this Agreement to any Person unless it concurrently assigns and transfers all of its rights and duties under the License Agreement to such Person. Any attempted assignment or delegation in violation of this Section 10.2 shall be void and of no effect. All validly assigned and delegated rights and obligations of either Party hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of such Party. In the event either Party seeks and obtains the other Partys consent to assign or delegate its rights or obligations to a Third Party, the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement.

10.3. Severability. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid, or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid, or unenforceable in any respect.

10.4. Governing Law and Service.

10.4.1. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

Form of Joint Press Release

Trevena Inc. and Forest Laboratories Announce a Collaborative Agreement

For Development of TRV027 for the Treatment of Acute Heart Failure

Forest Laboratories leads Trevenas $60 Million Series C Funding Round

All existing investors to also participate

May 9, 2013 King of Prussia, PA and New York, NY - Trevena Inc., (Trevena) a clinical stage pharmaceutical company and the leader in the discovery and development of G-protein coupled receptors (GPCR) biased ligands, and Forest Laboratories Holding Limited (Forest), a subsidiary of Forest Laboratories Inc. (NYSE:FRX), an international pharmaceutical company, announced today that they have entered into a collaborative licensing option agreement for the development of TRV027, an AT1R biased-ligand that recently completed Phase 2a clinical trials. Trevena expects to commence a 500-patient multi-center Phase 2b clinical trial in acute decompensated heart failure (ADHF) by year end.

Specific terms of the transaction were not disclosed but the agreement includes a $30 million equity investment by Forest in Trevena and the grant by Trevena to Forest of an option to exclusively license TRV027 on a worldwide basis following completion of the planned Phase 2b clinical trial which will be funded by Trevena. The parties will establish a joint development committee to oversee the development of TRV027 with Trevena retaining operational authority during the option period. Following the exercise of the option, Forest will make payments of up to $430 million, depending upon the achievement of future development and commercial milestones, plus royalties, and will have responsibility for the development and commercialization of the product.

We are excited to enter into this collaboration with Trevena, a leader in the ground breaking science of GPCR biased ligands. TRV-027 represents an important opportunity for Forest to build on our presence in the cardiovascular market and the hospital segment. ADHF is the fourth leading cause of hospitalizations in the United States and there has been no material change in the standard of care for patients with ADHF for decades. TRV-027 has the potential to be a significant new advance in the treatment of ADHF because it addresses the underlying pathophysiology of the disease which has been demonstrated in pre-clinical and early clinical work by Trevena. said David Solomon, Forests SVP of Corporate Development & Strategic Planning.

Forest Labs brings a wealth of drug development and commercialization experience to the TRV027 program, said Maxine Gowen, Trevenas President and Chief Executive Officer. This collaboration provides us with an opportunity to maximize the potential of this promising compound, and further validates our biased ligand approach to GPCR drug discovery.

Under the terms of the deal, Forest Labs will lead Trevenas $60 million Series C financing round with a $30 million investment. An executive of Forest Laboratories will also join Trevenas Board of Directors. Existing investors also participating in the round are Alta Partners, Healthcare Ventures, NEA, Polaris and Yasuda Enterprise Development Company.

About TRV027 and ADHF

TRV027 is an experimental intravenous drug for the treatment of acute decompensated heart failure (ADHF), currently in mid-stage clinical trials. It is a novel beta-arrestin biased ligand of the angiotensin II type 1 receptor (AT1R) that combines the proven benefits of angiotensin blockade with new beta-arrestin-mediated biology to preserve cardiac and renal function. Trevena recently presented the results of a Phase 2a study on the hemodynamic effects of TRV027 in patients with advanced heart failure with reduced ejection fraction, as a poster at the American College of Cardiology meeting in March 2013. Trevena successfully completed the Phase 2a study in October 2012, in which TRV027 was generally well-tolerated and produced a beneficial set of hemodynamic effects. The Phase 2a study was a randomized, double-blind, placebo-controlled, adaptive, ascending dose-titration study to evaluate the safety, tolerability, pharmacokinetics, and invasive hemodynamics of TRV027 in patients with stable NYHA Class 3 and 4 heart failure (NCT01187836).

The American Heart Association estimated that ADHF hospitalization costs the U.S. healthcare system more than $20 billion each year in direct spending. ADHF is already the leading reason for hospitalization of individuals over 65 years old in the United States, with over 1.3 million hospital admissions per year. ADHF is also the most costly diagnosis for Medicare. Despite the significance of this problem, current therapies are not producing meaningful improvements in patient outcomes. ADHF incidence is increasing globally, and both heart failure mortality and hospital re-admission following an ADHF event remain extremely high.
