Should the JSC not be able to reach unanimous agreement with respect to such future Commercialization within such ten (10) day period, either Party may refer such matter for resolution to the Chief Executive Officer of each Party and such Chief Executive Officers will attempt to resolve the matter in good faith within ten (10) days after the JSC has failed to reach unanimous agreement. In the event that the Chief Executive Officers cannot resolve such matter within such ten (10) day period, Catalyst may, upon delivery of written notice to EVL, terminate this Agreement effective as of the last day of the calendar month following such written notice.

(e) EVL shall make all payments under this Agreement free and clear of all tax deductions and withholdings, unless any such tax deduction or withholding is required by law in effect at the time of payment. Any Tax required to be withheld on amounts payable under this Agreement by EVL to Catalyst will be paid by EVL on behalf of Catalyst to the appropriate Governmental Authority, and EVL will furnish Catalyst with official receipts evidencing the payment of such Tax. Any such Tax required to be withheld will be treated as having been paid to Catalyst for all purposes of this Agreement.

6.2 Milestone Payment.

6.2.1 Subject to the terms and conditions of this Agreement, upon achievement of certain milestones, EVL shall make milestone payments to Catalyst as set forth below (each, a “Milestone Payment”). For the avoidance of doubt, each Milestone Payment shall be payable one-time only upon the first occurrence of the event triggering the respective milestone set forth below:

(a) [***] ($[***]) upon execution of this Agreement by both Parties; and

(b) [***] Dollars ($[***]) if upon Commercial Launch no Generic Equivalent had been commercially sold in the Territory by or on behalf of a Third Party; or

(c) [***] Dollars ($[***]) if upon Commercial Launch a Generic Equivalent had already been commercially sold in the Territory by or on behalf of a Third Party.

6.2.2 EVL shall make the applicable Milestone Payments payable to Catalyst under Section 6.2.1 (as applicable) within thirty (30) days following the completion of, and its receipt of an invoice for, the occurrence of the corresponding event, except for the Milestone Payment under Section 6.2.1(a), which shall be paid by EVL to Catalyst on the date hereof. Upon the occurrence of the applicable event for which a Milestone Payment is due and payable, Catalyst shall provide written notice thereof to EVL, along with an invoice for the corresponding Milestone Payment; provided, however, that Catalyst shall not be obligated to submit an invoice for the Milestone Payment under Section 6.2.1(a).

6.3 Payment; Expenses.

6.3.1 All payments under this Article 6 shall be made by wire transfer of immediately available funds to a bank account designated in writing by Catalyst.

6.3.2 Each Party shall bear its own costs and expenses associated with its responsibilities under this Agreement, except as expressly set forth in this Agreement. Any amounts payable under this Agreement which are not paid within thirty (30) days of their due date shall bear interest at a rate equal to [***] percent ([***]%) per annum, which shall be computed on the basis of a 365 day year.

6.4 Records and Audits. EVL and its Affiliates shall keep and maintain or cause to be maintained books and records pertaining to the calculation of Cost of Goods Sold, Net Sales and Net Profits during the Term and for two (2) years thereafter. Such books and records shall be maintained in accordance with GAAP and with all records and details necessary to enable Catalyst to verify the foregoing. All factors included in the determination of the Cost of Goods Sold, Net Sales and Net Profits shall be specific to the Product, reasonably documented, and available for independent audit purposes. Catalyst shall have the right once per calendar year, at its own expense, during the Term and for two (2) years thereafter, to have an independent public accountant, reasonably acceptable to EVL, audit the relevant financial books and records of account of EVL for up to the preceding three (3) years during normal business hours, upon reasonable advance notice, to determine or verify the applicable Cost of Goods Sold, Net Sales and Net Profits. If errors are found, any undisputed deficiency shall be paid within sixty (60) days following delivery of written documentation reasonably substantiating such deficiency. If errors

are discovered as a result of such audit in Catalyst’s favor exceeding ten percent (10%) of Net Profits for the period audited (which shall be no less than one (1) year), EVL shall reimburse Catalyst for the reasonable expense of such audit. In the event that there is any overpayment by EVL revealed (a) by an examination and review conducted on behalf of Catalyst, or (b) by an examination and review of a Net Profit Report by EVL’s accountants within one (1) year of delivery of such Net Profit Report, then EVL shall be permitted to carry over such overpayment and apply it against its payment obligations pursuant to Section 6.1.1 for future Calendar Quarters; provided, however, that if such overpayment is not fully recovered within the following two Calendar Quarters or EVL does not have continuing payment obligations pursuant to Section 6.1.1, then EVL may invoice Catalyst for the unrecovered overpayment and Catalyst shall pay such unrecovered overpayment to EVL within thirty (30) days of such invoice, by wire transfer of immediately available funds to a bank account designated in writing by EVL.

6.5 Accounting.

(a) The Parties acknowledge that any expenses or costs deducted from Net Sales under this Agreement may be based upon accruals, which accruals will be recognized and adjusted in compliance with GAAP; provided, however, that when the actual results become known relative to any accrued amount, any difference between the actual results and the accrual shall be accounted for in the subsequent payments due hereunder (subject to customary processing delays).

(b) To the extent that the difference between such accruals and the actual results has led to an underpayment, EVL shall pay Catalyst the amount of such underpayment on the next date payment is due to Catalyst hereunder. To the extent that the difference between such accruals and the actual results has led to an overpayment to Catalyst, EVL may, at its option, set-off such overpayments against subsequent payments to be made to Catalyst or issue an invoice for the amount of such overpayment, which shall be paid by Catalyst within forty-five (45) days after Catalyst’s receipt thereof.

(c) After the Term, EVL shall continue to reflect such deductions for accruals, and by the date that is twenty-four (24) months following the expiration of the Term or termination of this Agreement, as applicable, EVL shall reconcile (and give to Catalyst a report of such reconciliation of) all accrued calculations and deductions used in determining Net Sales with actual processed credits. If the report shows an underpayment to Catalyst, EVL shall pay Catalyst the amount of the underpayment at the time it gives the report to Catalyst. If the report shows an overpayment to Catalyst, Catalyst shall pay EVL the amount of the overpayment within thirty (30) days after receipt of such reconciliation.

ARTICLE 8. CONFIDENTIALITY AND PUBLIC DISCLOSURE

8.1 Treatment of Confidential Information.

A Receiving Party shall retain in strict confidence, and not disclose, divulge or otherwise communicate to any other Person, any Confidential Information of the Disclosing Party, whether received prior to or after the Effective Date, and shall not use any such Confidential Information for any purpose, except pursuant to the terms of, and as required to carry out such Receiving Party’s obligations under, this Agreement, except that each Receiving Party may disclose Confidential Information of the Disclosing Party to the officers, directors, employees, agents, accountants, attorneys, consultants, subcontractors or other representatives of the Receiving Party or its Affiliates (the “Representatives”) who, in each case, (a) need to know such Confidential Information for the limited purposes of the implementation and performance by the Receiving Party of this Agreement, (b) will use the Confidential Information only for such limited purposes, and (c) are bound by confidentiality obligations no less protective than those set forth in this Agreement.

8.1.1 A Receiving Party shall use at least the same standard of care in complying with its confidentiality obligations hereunder as it uses to protect its own Confidential Information of comparable sensitivity and to prevent and restrain the unauthorized disclosure of such Confidential Information by any of its Representatives, but in no event less than a reasonable standard of care. The Receiving Party shall be liable for any breach by any of its Representatives of the restrictions set forth in this Agreement.

8.1.2 Without limiting the generality of any of the foregoing, the Parties shall not make any disclosure of Confidential Information that would be reasonably likely to preclude the Disclosing Party from obtaining U.S. or foreign patents on any patentable invention or discovery described or otherwise embodied in such Party’s Confidential Information.

8.1.3 The Confidential Information of each Party includes information from Third Parties subject to confidentiality restrictions and disclosed by one Party to the other Party.

8.2 Release from Restrictions.

8.2.1 A Receiving Party may disclose Confidential Information to the extent that such Confidential Information disclosure is made in response to a valid order or subpoena of a court of competent jurisdiction in the Territory or other Governmental Authority of competent jurisdiction or otherwise required by law, in the reasonable opinion of counsel to the Receiving Party; provided, however, that, to the extent practicable, the Receiving Party shall first provide written notice to the Disclosing Party reasonably in advance under the circumstances in order to give the Disclosing Party a reasonable opportunity to quash such order or subpoena or to obtain a protective order requiring that the Confidential Information or documents that are the subject of such order or subpoena to be held in confidence by such court or Governmental Authority or, if disclosed, be used only for the purposes for which such order or subpoena was issued; and provided further that whether a disclosure order or subpoena is quashed or a protective order is obtained, any Confidential Information that may be disclosed in response to such court or Governmental Authority order or subpoena shall be limited to information that, in the reasonable opinion of counsel to the Receiving Party, is legally required to be disclosed in such response to such order or subpoena.

8.2.2 A Receiving Party may also disclose Confidential Information to the extent that such disclosure is made (i) to a Governmental Authority as required in connection with any filing, application or request for Regulatory Approval with respect to the Product, (ii) to comply with the reporting requirements of any Applicable Laws or any securities exchange on which the securities of the Receiving Party or its Affiliates are traded or (iii) to a Third Party to which a Receiving Party has a contractual obligation related to the Product, but only to the extent such information is required by such contractual obligation, provided that in each case (clauses (i), (ii) and (iii)), reasonable measures are taken to seek confidential treatment of such Confidential Information.

8.2.3 A Receiving Party may disclose this Agreement to a Third Party in connection with or in conjunction with (i) a proposed merger, consolidation, sale of assets that includes those related to this Agreement, (ii) a permitted assignment of this Agreement or (iii) loan financing, raising of capital, or sale of securities; provided, however, that the disclosing Party obtains an agreement for confidential treatment thereof on terms no less protective than those contained herein.

8.2.4 Any Confidential Information disclosed pursuant to this Section 8.2 shall maintain its confidentiality protection and nonuse restrictions for all purposes other than such disclosure.

8.3 No Implied Rights. Except as otherwise expressly set forth in this Agreement, nothing herein shall be construed as granting any Receiving Party any right, title, interest in or ownership of the Confidential Information, proprietary information or Intellectual Property of the Disclosing Party. For the avoidance of doubt, specific information disclosed as part of Confidential Information shall not be deemed to be in the public domain or in the prior possession of the Receiving Party merely because it is embraced by more general information in the public domain or by more general information in the prior possession of the Receiving Party.

8.4 Survival of Confidentiality Obligations. The confidentiality obligations of the Parties contained in this Article 8 shall remain binding on both Parties during the Term and for a period of five (5) years after the expiration of the Term or the termination of this Agreement, regardless of the cause of such expiration or termination.

8.5.1 No press release, public announcement, confirmation or other communication to the public or Third Parties regarding the existence or terms of this Agreement or related matters shall be made by either Party without the prior written consent of the other Party, including with respect to the form, content and timing of such press release, public announcement, confirmation or other communication to the public or Third Parties, except as provided Section 8.2 or in the following sentence. The Parties agree that a press release may be issued by Catalyst at or after the Effective Date in the form included on Exhibit C and that the Parties may make communication of any information specifically included in such press release.

8.5.2 Except as required by Applicable Laws or as to Labeling activities, no right, express or implied, is granted by this Agreement to either Party to use in any manner the name of the other Party or its Affiliates or any other trade name or trademark of such other Party or its Affiliates in connection with the performance of this Agreement. For clarity, it is understood that nothing herein shall prohibit either Party from using the name of the other Party (i) in certain of such Party’s disclosure documents, including those filed or disclosed in order to comply with its obligations under Applicable Laws or the listing standards or agreements of any national or international securities exchange, The New York Stock Exchange or The NASDAQ Stock Market or other similar laws of a Governmental Authority, (ii) to respond to an inquiry of a Governmental Authority, or (iii) in a judicial, administrative or arbitration Proceeding, or from disclosing the fact that it has granted or obtained a license to any Intellectual Property of such other Party so long as such use of the other Party’s name is limited to statements of fact and is not done in a manner to suggest or imply endorsement by such other Party.

8.6 Third Party Information

8.6.1 Catalyst has not and shall not (i) violate or misappropriate the trade secrets, know-how, or confidential information, or knowingly violate or misappropriate any other proprietary rights, of any Third Party in developing the Product, and will not communicate any

Third Party trade secrets to EVL or its Affiliates in connection with its rights and obligations under this Agreement without receiving permission from such Third Party and informing EVL of communication of such trade secrets, or (ii) provide or disclose any documents or information to EVL or its Affiliates unless Catalyst is the owner thereof, or otherwise has the full and legal right to do so.

8.7 Remedies. Each Party acknowledges and agrees that: (i) it will be too speculative to measure the damages that would be suffered by the other Party if such Party fails to comply with the obligations set forth in this Article 8 or in Article 12 and that, in the event of any such failure, such other Party will be irreparably harmed and will not have an adequate remedy at law, (ii) such other Party shall, therefore, be entitled, in addition to any other rights and remedies, to seek specific performance of such Party’s obligations and to seek immediate injunctive relief without having to post a bond, and (iii) such non-complying Party shall not assert, as a defense to any proceeding for such specific performance or injunctive relief, that such other Party will not be irreparably harmed or that such other Party has an adequate remedy at law.

by Catalyst (or its Affiliates) and a Third Party, providing for any royalty or other payment obligation with respect to the Product, or (iv) any patient’s participation in the Bioequivalence Studies, except, in each case, for those Liabilities for which EVL has an obligation to indemnify the Catalyst Indemnitees pursuant to Section 10.2, as to which Liabilities each Party shall indemnify the other Party to the extent of its respective liability for such Liabilities.

10.2 Indemnification by EVL. Subject to Section 10.3, EVL shall defend, indemnify and hold harmless each of Catalyst and its Affiliates, and each of their respective directors, officers and employees (each, a “Catalyst Indemnitee”) from and against any and all Liabilities arising, directly or indirectly, out of or in connection with Third Party claims, suits, actions, demands or judgments to the extent arising out of or relating to (i) any breach by EVL of any representation, warranty, agreement, undertaking or covenant under this Agreement; (ii) any negligence, gross negligence or willful misconduct by EVL or its Affiliates or sublicensees, past or present employees or agents; or (iii) product liability claims arising from the manufacture of the Product by EVL or its Affiliates, except, in each case, for those Liabilities for which Catalyst has an obligation to indemnify the EVL Indemnitees pursuant to Section 10.1, as to which Liabilities each Party shall indemnify the other Party to the extent of its respective liability for such Liabilities.

10.3 Notice and Procedures. If a Catalyst Indemnitee or an EVL Indemnitee (the “Indemnitee”) intends to claim indemnification under this Article 10, it shall promptly notify the other Party (the “Indemnitor”) in writing of any such alleged Liabilities. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any claim or action shall not relieve the Indemnitor of any obligation to the Indemnitee under this Section 10.3 except to the extent that the Indemnitor is materially prejudiced by such delay.

10.3.1 In the event that the Indemnitor does not assume and pursue in a timely and diligent manner the defense of any Third Party claim (but in no event later than thirty (30) days, or such shorter period as required under Applicable Laws), then the Indemnitor shall be deemed to have ceded control of such claim and the Indemnitee shall be entitled to appoint counsel of its own choice for such defense, at the cost and expense of the Indemnitor.

10.3.2 In the event that the Indemnitor assumes such defense, the Indemnitor shall have the right to control the defense thereof with counsel of its choice, provided that such counsel is reasonably acceptable to Indemnitee; and provided further that any Indemnitee shall have the right to retain its own counsel at its own expense, for any reason, including if representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflicts or differing interests between such Indemnitee and such Indemnitor reasonably represented by such counsel in such proceeding. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Liabilities covered by this Article 10.

10.3.3 The obligations of this Section 10.3 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor (unless the Indemnitor is deemed to have ceded control of the applicable Third Party claim under this Section 10.3).

10.3.4 Only Catalyst or EVL may claim indemnity under this Article 10 (on its own behalf or on behalf of its Indemnitees), and other Persons may not directly claim indemnity hereunder.

10.4 Other Product Liability Claims. To the extent either Party incurs any Liabilities arising from or in connection with any product liability claim with respect to the Product to the extent arising from the actions not subject to the indemnity obligations set forth in Section 10.1 or Section 10.2 (a “Product Claim”), then each Party shall be liable for such portion of the Liabilities in accordance with such Party’s allocation of the Net Profits pursuant to Section 6.1.1; provided, however, such Liabilities shall be shared initially by offsetting against the portion of Net Profits otherwise payable or retained pursuant to Section 6.1.1 and in the event of any shortfall thereafter, each Party’s share thereof shall be paid in accordance with such allocation. EVL shall have sole control in addressing, defending, managing and conducting any negotiations, litigation, threatened litigation or settlement regarding such Product Claim, using counsel of its choice. In the event that EVL does not respond to the Product Claim against Catalyst within (a) sixty (60) days following the notice of such claim or (b) ten (10) days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of a response to such Product Claim, whichever comes first, Catalyst shall have the right to control any such Product Claim, using counsel of its own choice. In the event of a Product Claim, the non-controlling Party shall cooperate fully with the controlling Party, including, if a party in such Product Claim, and the controlling Party shall keep the non-controlling Party and/or the non-controlling Party’s designated legal counsel reasonably informed as to the progress of such action. Neither Party shall enter into any settlement of the Product Claim, without the prior written consent of the other, such consent not to be unreasonably withheld, delayed or conditioned. Notwithstanding this Section 10.4, (a) Catalyst’s maximum aggregate liability pursuant to this Section 10.4 shall not exceed an amount equal to $[***], and (b) Catalyst shall have no liability under this Section 10.4 for product liability claims arising from the manufacture of the Product by any manufacturer other than [***].

10.5 Exclusive Remedy. The rights of the EVL Indemnitees and the Catalyst Indemnitees under this Article 10 shall be the sole and exclusive remedy of the EVL Indemnitees and the Catalyst Indemnitees, as the case may be, with respect to matters covered hereunder other than as provided in Article 8 and the termination provisions of Article 12.

ARTICLE 11. LIMITATION OF LIABILITY

NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, EXCEPT WITH RESPECT TO A BREACH OF ARTICLE 8 AND EXCEPT WITH RESPECT TO AMOUNTS PAYABLE ON LIABILITIES PURSUANT TO THE INDEMNIFICATION OBLIGATIONS SET FORTH IN ARTICLE 10, NO PARTY SHALL BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL, INCIDENTAL OR INDIRECT DAMAGES, INCLUDING FOR LOST PROFITS, OR LOSS OF OPPORTUNITY OR USE OF ANY KIND SUFFERED BY THE A PARTY, WHETHER IN CONTRACT, TORT OR OTHERWISE.
