Separation Agreement and General Release, dated December 15, 2017, by and between Endologix, Inc. and Robert D. Mitchell, including the Agreement for Independent Contractor Services attached as Exhibit A thereto

Endologix, Inc. (“Company”) and Robert D. Mitchell (“Employee”) hereby enter into the following Severance Agreement and General Release (this “Agreement”):

1.Employee shall retire from Company, and as a director and/or officer, as applicable, of each subsidiary of Company, and the employment relationship between Employee, Company and each subsidiary of Company will be separated effective December 31, 2017 (the “Separation Date”). In reliance on Employee’s representations and releases in this Agreement, Company will provide Employee with the following:

(a)    an Agreement for Independent Contractor Services in the form of Exhibit A attached hereto (the “Independent Contractor Agreement”);

(b)    (i) a lump sum severance payment, equivalent to six months base pay, in the gross amount of $195,250, (ii) payment of Employee’s earned bonus for the 2017 calendar year, in a gross amount to be determined by the Compensation Committee of the Board of Directors of the Company (the “Committee”) in February 2018 based upon achievement of the applicable corporate and individual performance objectives, and (iii) payment of Employee’s accrued vacation pay, each less applicable withholdings as required by law (collectively, the “Severance Payment”); and

(c)    payment of COBRA coverage for Employee under Company’s health insurance plans (medical, dental, prescription drug and group life) through June 30, 2018, if needed.

The Severance Payment shall be made in February 2018, following the Committee’s determination of Employee’s earned bonus for the 2017 calendar year, provided Employee executes, and does not revoke, this Agreement. The consideration described in this paragraph exceeds the amounts Employee would otherwise be eligible to receive under law, agreement and/or Company policies.

2.    Subject to Employee’s continued compliance with the covenants set forth in Section 7 of the Independent Contractor Agreement, Employee’s time-based stock options and restricted stock unit awards will continue to vest until the date of expiration of the Term of the attached Independent Contractor Agreement (December 31, 2018), or such earlier date if Employee terminates the Independent Contractor Agreement prior to the expiration of the Term, and Employee’s performance-based restricted stock awards will continue to vest in accordance with their terms. In addition, subject to Employee’s continued compliance with the covenants set forth in Section 7 of the Independent Contractor Agreement, if a Change in Control (as defined in Employee’s Employment Agreement dated February 1, 2014) occurs during the Term of the attached Independent Contractor Agreement, solely as a result of the Change in Control, all outstanding unvested time-based stock options and restricted stock unit awards and performance-based restricted stock awards held by Employee shall become fully vested and, if applicable, exercisable, in each case as of the date of the Change in Control. Employee and Company agree that Employee’s rights and obligations with regard to any equity in Company shall be governed by the terms of any applicable stock option, restricted stock, and restricted stock unit agreement(s) between Employee and Company, except as modified by this Agreement. Employee acknowledges and agrees that his right to exercise any vested stock options shall expire in accordance with the terms of the applicable stock option agreement, as extended by this Agreement and the Independent Contractor Agreement. For purposes of clarity, Employee’s right to exercise any vested stock options shall expire 90 days following the date of expiration of the Term of the attached Independent Contractor Agreement (December 31, 2018) or such earlier date if Employee terminates the Independent Contractor Agreement prior to the expiration of the Term. Employee further

acknowledges and agrees that any incentive stock options held by Employee will cease to be so characterized if exercised by Employee more than 90 days following the Separation Date.

3.    As consideration for Company to enter into this Agreement, Employee agrees that he will continue to provide consulting support to Company pursuant to the Independent Contractor Agreement and will not file any complaints or other proceedings against Company or any Released Party (as defined below) with any court or arbitrator based on any claim released by this Agreement, and that if any court or arbitrator assumes jurisdiction of any proceeding against Company or any Released Party on his behalf, Employee will immediately take all actions necessary to assure the matter is dismissed or closed. This Agreement does not limit Employee’s right to file a charge or complaint with any state or federal agency, or to cooperate in such a matter, although Employee expressly waives and relinquishes all right to any relief that any governmental agency may obtain on his behalf.

4.    In exchange for the consideration referred to in paragraph 1 above, Employee waives and releases all claims, known and unknown, which he might otherwise have had, as of the date of execution of this Agreement, against Company or any of its parent or affiliated companies, or any of its or their respective officers, directors, stockholders, employees, attorneys, insurers, agents, successors or assigns (collectively, the “Released Parties”), including but not limited to claims regarding any aspect of Employee’s employment or compensation, the cessation of Employee’s employment, the Age Discrimination in Employment Act of 1967, the Americans with Disabilities Act of 1990, Title VII of the Civil Rights Act of 1964, 42 U.S.C. section 1981, the Fair Labor Standards Acts, the California Fair Employment and Housing Act, California Government Code section 12900, et seq., the Unruh Civil Rights Act, California Civil Code section 51, all provisions of the California Labor Code and the Employee Retirement Income Security Act, 29 U.S.C. section 1001, et seq., all as amended, any other federal, state or local law, regulation or ordinance or public policy, contract, tort or property law theory, or any other cause of action whatsoever that arose on or before the date Employee executes this Agreement.

5.    It is further understood and agreed that as a condition of this Agreement, all rights under Section 1542 of the Civil Code of the State of California are expressly waived by Employee. Such Section reads as follows:

Notwithstanding Section 1542, and for the purpose of implementing a full and complete release and discharge of the Released Parties, Employee expressly acknowledges that this Agreement is intended to include and does include in its effect, without limitation, all claims which Employee does not know or suspect to exist in Employee’s favor against the Released Parties at the time of execution hereof, and that this Agreement expressly contemplates the extinguishment of all such claims.

6.    Employee acknowledges that he is entering into this Agreement in return for the consideration referred to in paragraph 1 above. Employee further agrees that no promises, representations, or inducements have been made to him which caused him to sign this Agreement other than those which are expressly set forth above in paragraph 1. This Agreement contains all of the terms, promises, representations, and understandings made between the parties regarding the subject matter of this Agreement; provided, however, that notwithstanding any provision of this Agreement to the contrary, Employee’s Proprietary Information and Inventions Agreement and Indemnification Agreement shall remain in full force and effect in accordance with their terms.

7.    Employee agrees not to make any written or oral statements about Company or any of the Released Parties that are disparaging, including via internet and media.  Nothing in this Agreement shall preclude Employee from communicating or testifying truthfully (a) to the extent expressly required by law, (b) to any state or federal government agency, (c) in response to subpoena to testify issues by a court of competent jurisdiction, or (d) in any action to challenge or enforce the terms of this Agreement.

8.    Employee acknowledges that he has been paid all wages and Company benefits due and owing as of the Separation Date, less appropriate withholdings, including all accrued vacation pay, and is not owed any additional amounts, other than the Severance Payment and any other amounts which Employee may be entitled under this Agreement.

9.    Employee will represent that he has returned all Company property in his possession, whether in tangible or electronic form, including, without limitation, computers, phones, printers, furniture and all data, analysis and reports regarding Company and its business, operations, intellectual property, other assets and products or potential products. Notwithstanding the foregoing, Employee may retain the laptop computer and mobile phone provided to him by Company.

10.    This Agreement will be interpreted in accordance with the laws of the State of California. All provisions of this Agreement are severable. Accordingly, if any provision of this Agreement is found to be unenforceable, the other provisions shall remain fully valid and enforceable.

11.    Employee acknowledges that: (a) Company has advised Employee to consult with an attorney and tax advisor prior to the execution of this Agreement; (b) Employee has had the opportunity to discuss this Agreement with his attorneys and tax advisors, to the full extent he so desires; (c) Employee has carefully read and fully understands all of the provisions of this Agreement; (d) Employee fully understands that this Agreement releases all of his claims, both known and unknown, against Company and the Released Parties; (e) Employee signs this Agreement voluntarily; and (f) Employee has the capacity to enter into this Agreement.

12.    Employee understands that he has twenty-one (21) days to review and fully consider this Agreement before signing it, and that he may take as much of that period as he wishes prior to signing it. Employee also understands that within seven (7) days of the date of signing this Agreement, he has the right to revoke this Agreement. Any such revocation must be made in a signed writing delivered to Company, c/o John McDermott, Chief Executive Officer, within the seven (7) day revocation period. If Employee timely revokes this Agreement, it shall not be effective or enforceable, Employee must immediately return the Severance Payment and any other benefits received by Employee prior to the expiration of such revocation period and Employee will not thereafter receive any other benefits described in this Agreement.
