This Separation Agreement (the “Agreement”), dated October 30, 2018, is by and between Xxxx Xxxxx (“Executive”) and Synergy Pharmaceuticals Inc., a Delaware corporation (the “Company”).

WHEREAS, Executive’s status as an employee of the Company will end effective on October 31, 2018 (the “Termination Date”); and

WHEREAS, Executive and the Company desire to assure a smooth and effective transition of Executive’s duties and to wind-up their employment relationship amicably; and

WHEREAS, the payments and benefits being made available to Executive pursuant to this Agreement are intended to satisfy all outstanding obligations under that certain Executive Employment Agreement, dated May 11, 2009, between Executive and the Company, as amended on February 10, 2010, May 2, 2011, December 28, 2012, January 7, 2015, December 29, 2016, November 7, 2017 and December 18, 2017, (the “Employment Agreement”) and to settle any and all other obligations owed by the Company to the Executive.

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, Executive and the Company, intending to be legally bound, hereby agree as follows:

1. Termination Date. Executive acknowledges that his status as an employee, officer and director (and as a member of each committee of the Board of Directors) of the Company and each of its subsidiaries will end on the Termination Date. From the date hereof until the Termination Date, Executive shall remain employed by the Company pursuant to the terms of the Employment Agreement. Executive understands that as a condition to receiving the Severance Benefits (as defined below), he must execute the General Release attached hereto as Exhibit A (the “General Release”) within twenty-one (21) days after the Termination Date and not revoke the General Release during the seven (7) day period after Executive signs the General Release. The General Release will become effective on the eighth (8th) day after Executive signs the General Release, so long as it has not been revoked by Executive before that date (the “Effective Date”). Executive and the Company agree that Executive shall resign as a member of the Company’s Board of Directors (the “Board”) and each committee thereof effective as of the Termination Date.

2. Separation Payments and Benefits. Without admission of any liability, fact or claim, the Company hereby agrees, subject to Executive’s timely execution and non-revocation of the General Release and Executive’s compliance with Executive’s obligations pursuant to this Agreement, the General Release and the Surviving Restrictive Covenants (as defined below), to provide Executive the severance payments and benefits set forth below in this Section 2 (collectively, the “Severance Benefits”):

(a) Severance Payment. The Company shall pay Executive a lump sum cash payment of $648,900 (the “Severance Payment”). The Severance Payment

SMRH:227903548.2			1
00000000.0.XXX

shall be paid in a lump sum within ten (10) business days after Executive executes the General Release, properly delivers it to the Company and the General Release becomes irrevocable.

(b) Benefits Coverage; Indemnification. If Executive is enrolled in the Company’s group medical, vision and/or dental plans on the Termination Date, Executive may elect to continue Executive’s participation and that of Executive’s eligible dependents in those plans for a period of time under COBRA. Executive may make such an election whether or not Executive accepts this Agreement. However, if Executive accepts this Agreement and Executive timely elects to continue Executive’s participation and/or that of Executive’s eligible dependents in such plans, the Company will pay the full premium cost of Executive’s and his dependents’ COBRA continuation coverage until December 31, 2019. If the Company’s contributions end before Executive’s entitlement to coverage under COBRA concludes, Executive may continue such coverage by paying the full premium cost himself. Notwithstanding the foregoing, in the event that the Company’s payment of the COBRA premium contributions as described under this Section 2(b), would subject the Company to any tax or penalty under the Patient Protection and Affordable Care Act (as amended from time to time, the “ACA”) or Section 105(h) of the Internal Revenue Code of 1986, as amended (the “Code”), or applicable regulations or guidance issued under the ACA or Code Section 105(h), Executive and the Company agree to work together in good faith to restructure such benefit in a manner that complies with or is exempt from Code Section 409A. The Company agrees to provide D&O coverage for the Executive under the Company’s D&O policy (with coverage no less favorable than the coverage provided for the Company’s then existing directors and officers) for a period of six (6) years following the Termination Date

(c) Equity Awards. Any unvested stock options granted to Executive by the Company will accelerate and become fully vested and exercisable as of the Termination Date and each stock option granted to Executive by the Company (including, without limitation, such stock options that receive accelerated vesting under this Section 2(c)) shall remain exercisable for the remainder of its term (assuming no termination of employment occurred).

(d) 2018 Bonus. Executive shall receive a bonus for the 2018 fiscal year in the same manner and in the same amount as if he remained employed by the Company through the date of payment, but pro-rated based on the number of days he was employed by the Company during the 2018 fiscal year in relation to the number of days in the 2018 fiscal year. Any such bonus shall be paid to Executive in a lump sum cash payment on the first payroll date in April 2019.

(e) Taxes; Tax Payments. Executive understands and agrees that all payments under this Agreement will be subject to appropriate tax withholding and other deductions, as and to the extent required by law.

(f) Sole Separation Benefit. Executive agrees that the payments and benefits provided in Section 2 of this Agreement are not required under the Company’s normal policies and procedures and are provided solely in connection with this Agreement. Executive further acknowledges and agrees that the payments and benefits referenced in Section 2 of this Agreement constitute adequate and valuable consideration, in and of themselves, for the promises contained in this Agreement and the General Release.

(g) Continued Obligations. Executive acknowledges and agrees that Executive shall continue to be subject to, and abide by, Section 2 (Confidential Information) and Section 3 (Non-Competition; Non-Solicitation) of the Employment Agreement and the terms of the Nondisclosure and Assignment of Inventions Agreement executed by Executive on ________ and attached hereto as Exhibit B. (such provisions are collectively referred to herein as the “Surviving Restrictive Covenants”), which shall continue to apply and remain in full force and effect. If the Company believes that Executive has breached any provision of this Agreement, the General Release or the Surviving Restrictive Covenants, then it shall provide Executive with written notice of such alleged breach within 30 days after it has knowledge of the occurrence thereof and shall provide Executive with 30 days to cure such alleged breach (any breach so cured shall not be deemed a breach of this Agreement, the General Release or any of the Surviving Restrictive Covenants). If the Executive so breaches this Agreement or any of the Surviving Restrictive Covenants, and fails to cure said breach as provided in the immediately preceding sentence after the required notice by the Company, the Company shall have no further obligation to provide any Severance Benefits. The Company acknowledges and agrees that it is not aware of any breach by Executive of any of the Surviving Restrictive Covenants or any provision of this Agreement. Notwithstanding the foregoing, pursuant to 18 U.S.C. 1833(b), Executive shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Further, if Executive files a lawsuit for retaliation by the Company or its affiliates for reporting a suspected violation of law, he may disclose the trade secret to his attorney and use the trade secret information in the court proceeding, if Executive (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.

3. Certain Additional Surviving Rights. Notwithstanding anything contained in this Agreement or the General Release to the contrary, (i) Executive’s rights under Section 1.5(e) of the Employment Agreement remain in full force and effect to the extent they become applicable and (ii) Executive shall remain eligible to receive a Realization Bonus (as defined in the Employment Agreement) pursuant to Section 1.5(b) of the Employment Agreement in accordance with the terms thereof following the parties’ execution of this Agreement (provided that, Executive’s termination of employment shall be treated as a termination of employment by

SMRH:227903548.2			3
00000000.0.XXX

the Company without Cause (as defined in the Employment Agreement), and accordingly, Section 1.5(b)(vi) of the Employment Agreement shall not be applicable).

4. Full Payment; Termination of Employment Agreement. Other than as set forth in Sections 2 and 3 above, Section 8 below or in the General Release, Executive shall not be entitled to any other payments including but not limited to bonuses, commissions, or other cash or non-cash awards, penalties, interest or attorneys’ fees from the Company or any of its subsidiaries; provided, however, that to the extent unpaid as of the Termination Date, the Company shall pay the Compensation Payment (as defined in the Employment Agreement) to Executive as provided in Section 4.1 of the Employment Agreement. On the Termination Date all provisions of the Employment Agreement, other than as specifically provided for herein, the Surviving Provisions and Section 7 of the Employment Agreement, shall terminate and Executive shall have no further rights thereunder.

5. Transition; Cooperation; Transfer of Company Property; Non-Disparagement. Executive further agrees that:

(a) Transition. Executive acknowledges and agrees that Executive shall collaborate with the Company in the development and issuance of any internal or external communications made by the Company addressing Executive’s separation pursuant to this Agreement.

(b) Cooperation. Commencing on the date hereof and continuing during the forty eight (48) month period immediately after the Termination Date (the “Cooperation Period”), Executive agrees to reasonably cooperate with the Company in its efforts to prosecute or defend itself against any claim, suit, demand or cause of action (not brought by the Company against Executive or by Executive against the Company) about which Executive has knowledge. Notwithstanding the immediately preceding sentence, following the Termination Date, (a) the Company shall provide Executive with advance written notice of such required cooperation within a reasonable period of time prior to the date on which such cooperation will be required, (b) such cooperation shall not create a conflict with any of Executive’s obligations or duties to his then current employer, (c) such cooperation shall be provided at reasonable times and locations, (d) the Executive shall report to, and take direction from, only the Company’s Chief Executive Officer in providing the cooperation described herein, (e) the Company shall reimburse Executive (in compliance with Code Section 409A) for all reasonable expenses incurred by him in complying with this Section 5(b), subject to appropriate itemization and substantiation of such expenses.

(c) Return of Company Property. Executive shall on or before the date that is ten (10) days following the Termination Date, return to the Company all written Confidential Information (as defined in the Employment Agreement) in Executive’s possession (including, but not limited to, Company-provided credit cards, building or office access cards, keys, computer or other business equipment, manuals, files, documents, records, software, employee database and other data), and that Executive will not retain any copies, compilations, extracts, excerpts, abstracts, summaries or other notes

SMRH:227903548.2			4
00000000.0.XXX

of any such manuals, files, documents, records, software, customer or employee database or other data files, memoranda, records, and other documents, and any other physical or personal property which are the property of the Company and which Executive had in Executive’s possession, custody or control, including any computers, cellular phones, tablets, PDAs or similar business equipment; provided, however, that if Executive has inadvertently retained non-material Confidential Information or property of the Company (“Covered Information”), it shall not be a breach of this Agreement or any of the Surviving Provisions if (i) promptly after becoming aware of his possession of such Covered Information Executive returns it to the Company, (ii) Executive has not disclosed such Covered Information in violation of the Surviving Provisions, and (iii) no loss or damage that is more than de minimis has been caused to the Company as a result of Executive’s retention of such Covered Information. Notwithstanding this Section 5(c), the Company may provide Executive with Confidential Information and Company property in connection with his obligations under Section 5(b) hereof and Executive acknowledges and agrees that he shall return all such Confidential Information and Company property (including his laptop) within ten (10) days after the end of Executive’s obligations under Section 5(b) hereof or such earlier date as is requested reasonably in advance in writing by the Company (with the same procedures to apply regarding the inadvertent retention of Covered Information as set forth in the immediately preceding sentence)

(d) Mutual Non-Disparagement. From and after the date of this Agreement, the Executive shall not make any public or private statement (whether orally, in writing, via electronic transmission, or otherwise) that disparage, denigrate or malign the Company, in any case, in a manner that would be reasonably expected to be materially harmful to the Company. From and after the date of this Agreement, the Company shall cause each of the members of the Board and each of the Company’s senior executive officers not to, and shall not make any official press releases that disparage, denigrate or malign the Executive, in any case, in a manner that would be reasonably expected to be materially harmful to the Executive. The foregoing limitations in this Section 5(d) shall not be violated by truthful statements made (i) to any governmental authority or (ii) which are in response to legal process, required governmental testimony or filings, or administrative or arbitral proceedings (including, without limitation, depositions in connection with such proceedings).

6. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties hereunder shall be governed by, the laws of New York, without regard to any principles of conflicts of laws.

7. Section 409A. It is intended that each installment of the payments provided hereunder constitute separate “payments” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). To the extent that any provision of this Agreement is ambiguous as to its compliance with Code Section 409A, the provision will be read in such a manner so that all payments hereunder comply with Code Section 409A. To the extent any expense reimbursement or the provision of any in-kind benefit under this Agreement is determined to be subject to Code

SMRH:227903548.2			5
00000000.0.XXX

Section 409A, the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement, or the amount of in-kind benefits to be provided, in any other calendar year (except for any lifetime or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year immediately following the calendar year in which Executive incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit. For purposes of Code Section 409A, Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

8. Miscellaneous. This Agreement, together with the General Release, the Surviving Provisions and Section 7 of the Employment Agreement, is the entire agreement between the parties with regard to the subject matter hereof. Executive and the Company acknowledge that there are no other agreements, written, oral or implied regarding such subject matter, and that neither the Company nor Executive may rely on any prior negotiations, discussions, representations or agreements regarding the subject matter hereof. Whenever possible, each provision of this Agreement shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision shall be held to be prohibited or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting the remainder of such provision or any of the remaining provisions of this Agreement. The Company represents that the Board of Directors of the Company has duly and validly authorized this Agreement. This Agreement may be modified only in writing, and such writing must be signed by both Executive and the Company and recited that it is intended to modify this Agreement. Within 10 days after the Company’s receipt of substantiation of expenses, the Company shall pay to Dechert LLP up to $10,000 of legal fees incurred by Executive to Dechert LLP in connection with the negotiation and execution of this Agreement and the General Release.
