EMPLOYMENT AGREEMENT 

This EMPLOYMENT AGREEMENT (the “Agreement”) is made and entered into as of July 3, 2015 by and between AHS Management
Company, Inc. (the “Employer”), and David T. Vandewater, an individual (“Employee”). 
 WITNESSETH:

 WHEREAS, the Employer desires to enter into this Agreement with Employee and to provide him with the benefits set forth herein
in recognition of the valuable services he has and will render to the Employer, and for the purposes evidenced herein; 
 WHEREAS,
Employee is ready and willing to render the services provided for, and on the terms and conditions set forth herein, and he is willing to refrain from activities competitive with the business of the Employer during the term of and after this
Agreement on the terms and conditions set forth herein; 
 WHEREAS, in serving as an employee of the Employer, Employee will
participate in the use and development of confidential proprietary information about the Employer, its customers and suppliers, and the methods used by the Employer and its employees in competition with other companies, as to which the Employer
desires to protect fully its rights; and 
 NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements
herein set forth, the parties hereto agree as follows: 
 1. Employment. The Employer hereby continues to employ Employee and Employee
continues to accept such employment with the Employer, subject to the terms and conditions set forth herein. Employee is employed as President and Chief Executive Officer and shall report directly to the Board of Directors (the
“Board”) of the Employer and shall perform all duties and services incident to such position, and such other similar duties and services as may be prescribed by the governing documents of the Employer or established by the Employer,
or its parent corporation from time to time. During his employment hereunder, Employee shall devote his best efforts and attention, on a full-time basis, to the performance of the duties required of him as an employee of the Employer. 

2. Principal Office. Employee’s principal office and normal place of work is located at the Employer’s principal executive
offices in the Nashville, Tennessee metropolitan area (“Principal Office”). 
 3. Compensation. 

(a) As compensation for services rendered by Employee hereunder, Employee shall receive: 

(1) Salary. The Employee shall be paid an annual salary of $800,000, or such higher salary as shall be approved by the
compensation committee of Board from time to time, which shall be payable in arrears in equal monthly installments (“Salary”). 












 (2) Bonus. 

(i) For the period beginning on the date hereof and ending December 31, 2015, the Employer shall pay Employee a bonus
based on the amount Employee would have received pursuant to Section 3(a)(2) of that certain Employment Agreement (the “Former Employment Agreement”), executed January 6, 2009, by and between Employee and Employer,
provided that the targets will be adjusted in consultation with the Employer’s CEO within 90 days of the Effective Date. Such bonus and objectives may be stated in a written incentive compensation program which the Employer intends to qualify
as “performance based compensation” described in Internal Revenue Code (the “Code”) Section 162(m). 

(ii) For the period beginning January 1, 2016, the Employer shall pay Employee an annual cash bonus in an amount to be
determined by the Board based on whether certain reasonable objectives established by the Board prior to the beginning of each fiscal year as set forth in the Employer’s Incentive Compensation Plan (the “Plan”) have been met.
Such bonus and objectives may be stated in a written incentive compensation program which the Employer intends to qualify as “performance based compensation” described in Code Section 162(m). 

(iii) Bonuses will be earned as of the last day of the subject fiscal year, regardless of any subsequent termination of
employment, and will be payable on or before the earlier of seventy-five (75) days after fiscal year end or fifteen (15) days after presentation of the audited financial statements for such fiscal year to the Board. 

(3) Fringe Benefits. Employee shall be entitled during the Term of this Agreement (as defined below) to such other
benefits of employment with Employer as are now or may hereafter be in effect for Employer’s senior executives with duties comparable to Employee including, without limitation, all incentive and deferred compensation, pension, life and other
insurance, disability (insured and uninsured), medical and dental and other benefit plans or programs, paid time off and equity-based grants as approved by the Board pursuant to the operative plans and applicable documents for each benefit. 

(4) Expenses. During the Term of this Agreement, Employer shall reimburse Employee promptly for all reasonable travel,
entertainment, parking, business meeting and similar expenditures in pursuance and furtherance of Employer’s business upon receipt of reasonable supporting documentation as required by Employer’s policies applicable to its officers and
other key employees generally. 
 (5) Withholdings. All amounts payable to Employee hereunder shall be subject to such
deductions or withholdings as are required by law or the policies of the Employer or as may be authorized or directed by Employee. Furthermore, any monies owed to Employee by Employer may be offset by any monies owed the Employer by Employee,
provided, however, that any offset of amounts considered to be deferred compensation under Section 409A of the Code shall be limited in accordance with Treas. Reg. Section 1.409A-3(j)(4)(xiii). 

(b) Benefits Review. Employee’s Salary, bonus and benefits payable hereunder will be subject to annual review by
the compensation committee of the Board, in consultation with the CEO, and such compensation may be increased, but not decreased (except in connection with, and in the same percentage as, a broad-based corporate officer decrease), in the good faith
determination of the compensation committee of the Board, in consultation with the CEO. Employee understands and acknowledges that the opportunity of an annual salary and benefit review by the Board shall not be construed in any manner as an express
or implied agreement by the Employer to raise or increase his salary or benefits.

 (c) Indemnification. This Agreement hereby incorporates and makes a
part of this agreement the Indemnification Agreement dated January 1, 2002, by and between Employee and Ardent Health Services, LLC. The provisions and rights guaranteed under that Agreement shall survive any termination of this Agreement. 

4. Confidential Information and Trade Secrets. 

(a) Trade Secrets. Employee recognizes that Employee’s position with the Employer requires considerable
responsibility and trust, and, in reliance on Employee’s loyalty, the Employer may entrust Employee with highly sensitive confidential, restricted and proprietary information involving Trade Secrets and Confidential Information. For purposes of
this Agreement, a “Trade Secret” is any scientific or technical information, design, process, procedure, formula or improvement that is valuable and not generally known to competitors of the Employer. “Confidential
Information” is any data or information, other than Trade Secrets, that is important, competitively sensitive, and not generally known by the public, including, but not limited to, the Employer’s business plan, acquisition targets,
training manuals, product development plans, pricing procedures, market strategies, internal performance statistics, financial data, confidential personnel information concerning employees of the Employer, supplier data, operational or
administrative plans, policy manuals, and terms and conditions of contracts and agreements. 
 (b) Non-Disclosure.
Except as required to perform Employee’s duties hereunder, Employee will not use or disclose the terms of this Agreement or any Trade Secrets or Confidential Information of the Employer during employment, or at any time after termination of
employment; provided, however, that Employee may disclose the terms of this Agreement and Confidential Information (1) to Employee’s spouse and Employee’s representatives, agents and advisors who are advising Employee
with respect to this Agreement, but only for legitimate business purposes related to the negotiation and performance of this Agreement and with a covenant from those persons to keep such information confidential in accordance with this
Section 4 or (2) to the extent that disclosure is required by applicable law or order; provided that as soon as reasonably practicable before such disclosure, Employee gives the Employer prompt written notice of such disclosure to enable
the Employer to seek a protective order or otherwise preserve the confidentiality of such information. 
 (c) Material
Surrender. Upon termination of Employee’s employment with the Employer, Employee will surrender to the Employer all files, correspondence, memoranda, notes, records, manuals or other documents or data pertaining to the Employer’s
business or Employee’s employment (including all copies thereof) however prepared and whether maintained in paper or electronic format. Employee will also leave with the Employer all materials involving any Trade Secrets or Confidential
Information of the Employer. All such information and materials, whether or not made or developed by Employee, shall be the sole and exclusive property of the Employer, and Employee hereby assigns to the Employer all of Employee’s right, title
and interest in and to any and all of such information and materials.

 5. Covenants. Employee shall be subject to the following covenants and obligations:

 (a) Non-Competition Covenant. While employed by the Employer, Employee shall not compete or plan or prepare to
compete with the Company regarding the ownership, investment in, management of or operation of free standing hospitals owned, operated or managed by the Company that provide medical-surgical healthcare services (each, a “Hospital”).
Employee shall not compete with the Company for a period of thirty-six (36) months following the termination of his employment anywhere in the United States of America. 

(b) Non-Solicitation Covenant. Following the termination of Employee’s employment with the Employer, for a period
equal to the term of the non-competition covenant under Section 5(a), Employee shall not directly or indirectly solicit the services of or otherwise induce or attempt to induce any Company Employee to sever his/her employment relationship with
the Company. For purposes of this Section “Company Employee” shall mean (1) any employee who performs or performed (on the Termination Date or within the previous six (6) months of such date) any of his/her services at the
Employer’s Principal Office and (2) any member of the senior management staff of any Hospital. Prior to the initiation of any conduct prohibited under this Section, Employee may request that the Company waive application of this Section to
said conduct. Granting of such request, however, shall be at the Company’s sole discretion. 
 (c) Scope and
Duration; Severability. The Company, Employer and Employee understand and agree that the scope and duration of the covenants contained in this Section 5 are reasonable both in time and geographical area and are necessary and fair to protect
the business of the Company. Except as otherwise stated herein, such covenants shall survive the termination of Employee’s employment. It is further agreed that such covenants shall be regarded as divisible and shall be operative as to time and
geographical area to the extent that they may be made so and, if any part of such covenants are declared invalid or unenforceable, the validity and enforceability of the remainder shall not be affected. 

(d) Assignment. Employee agrees that the covenants contained in this Section 5 shall inure to the benefit of any
successor or assign of the Company, with the same force and effect as if such covenant had been made by Employee with such successor or assign. 

(e) Exclusion. Notwithstanding the provisions of this Section 5, Employee’s non-competition obligations shall
not preclude Employee from owning less than one percent (1%) of the voting power or common interest in any publicly traded corporation conducting business activities in the healthcare industry in competition with the Company or any affiliate.

 (f) Company. For purposes of this Section 5, “Company” shall mean EGI-AM Holdings, L.L.C. and
all of its directly or indirectly owned subsidiaries. 
 6. Program Participation. Employee represents that he is, and will for the
term of this Agreement be eligible to participate in Medicare, Medicaid, CHAMPUS, TriCare, and other federal health programs, and Employee shall not have been sanctioned by any federal or state governmental agency or department and/or listed on the
Health and Human Services Office of the Inspector General, Cumulative Sanctions Report, or excluded by the General Services Administration, as set forth on the List of Excluded Providers (see http://oig.hhs.gov/fraud/exclusions.html and
http://epls.arnet.gov). 

  
 -4- 













 7. Specific Enforcement. Employee specifically acknowledges and agrees that the
restrictions set forth in Sections 4 and 5 hereof are reasonable and necessary to protect the legitimate interests of the Employer and that the Employer would not have entered into this Agreement in the absence of such restrictions. Employee further
acknowledges and agrees that any violation of the provisions of Sections 4 and 5 hereof will result in irreparable injury to the Employer, that the remedy at law for any violation or threatened violation of such Sections will be inadequate and that
in the event of any such breach, the Employer, in addition to any other remedies or damages available to it at law or in equity, shall be entitled to temporary injunctive relief before trial from any court of competent jurisdiction as a matter of
course and to permanent injunctive relief without the necessity of proving actual damages. The Employer shall also have available all remedies provided under state and federal statutes, rules and regulations as well as any and all other remedies as
may otherwise be contractually or equitably available. In addition to any other remedy herein granted or available to Employer, either at law or in equity, Employee shall forfeit and forever release any claim or right Employee may have to any
benefits remaining under this Agreement from the date Employee breached Section 5 of this Agreement. Any monetary damages sought by the Employer under this Section shall not include the benefits forfeited under this Section. 

8. Term. This Agreement shall continue until terminated in the manner set forth herein (the “Term”). The Agreement
shall commence on the Closing Date (the “Effective Date”), as such term is defined in that certain Purchase and Sale Agreement (“Purchase Agreement”) by and among Ardent Medical Services, Inc., AHS Newco 14, LLC,
AHS New Mexico Holdings, Inc., Ardent Legacy Acquisitions, Inc., and Ventas, Inc. of even date herewith; provided, however, that this Agreement is conditioned in all respects on the closing of the transactions contemplated in the Purchase Agreement.
The date upon which this Agreement and Employee’s employment hereunder shall terminate, whether pursuant to the terms of this Section or pursuant to any other provision of this Agreement shall be referred to herein as the “Termination
Date.” 
 9. Termination Upon Death of Employee. In the event Employee dies during the Term of this Agreement, this Agreement
shall immediately terminate and neither Employee nor the Employer shall have any further obligations hereunder except for unpaid salary or unreimbursed substantiated expenses owed at the time of death. Such unpaid salary and unreimbursed expenses
shall be paid within ninety (90) days of the Employee’s death. 
 10. Termination by Employee Without Good Reason. Employee
may terminate this Agreement without Good Reason (as defined in Section 11 below) thirty (30) days after delivery to the Employer written notice of his intent to terminate this Agreement. In the event Employee’s employment hereunder
is terminated in accordance with this Section, the Employer shall have no further obligation to make any payments to Employee hereunder except for unpaid salary or unreimbursed expenses that have accrued but have not been paid as of the Termination
Date. 
 11. Termination by Employee For Good Reason. Employee may terminate this Agreement thirty (30) days after delivery to
the Employer of written notice of his intent to terminate this Agreement (“Notice Period”), which notice alleges the occurrence of: (a) a material diminution in Employee’s office, duties or responsibilities after the
Effective Date, or (b) a material breach by the Employer of this Agreement. Said notice under this Section must be received by the Employer within thirty (30) days of the occurrence of the event which Employee contends allows him to
terminate the Agreement under this Section or Employee shall have waived any right to terminate the Agreement for said event. Notwithstanding the foregoing, however, Employee shall not have the ability to terminate this Agreement if the facts
alleged in such written notice have been cured prior to the expiration of the Notice Period under this Section. In the event Employee’s employment hereunder is terminated in accordance with this Section, the Employer shall pay Employee
(i) any unpaid salary and unreimbursed substantiated expenses within ninety (90) days of the Termination Date and (ii) the salary and benefits as set forth in Sections 14(b) and (c) of this Agreement. Employee’s obligations
under Sections 4 and 5 hereof shall survive the termination of this Agreement pursuant to this Section. 

  
 -5- 













 12. Termination by the Employer for Cause. The Employer shall have the right at any
time to terminate Employee’s employment immediately for cause. The term “Cause” shall mean (a) Employee’s willful refusal to perform, or gross negligence in performing, the reasonable duties of Employee’s office

governmental authority) or other debarment from contracting with any governmental authority. Employee’s obligations under Sections 4 and 5 hereof shall survive in full force and effect the termination of the Agreement pursuant to this Section.
In the event Employee’s employment hereunder is terminated in accordance with this Section, the Employer shall have no further obligation to make any payments to Employee hereunder except for unpaid salary or unreimbursed expenses that have
accrued but have not been paid as of the Termination Date.

the contrary herein, in the event of a termination pursuant to this Section 13(a), Section 5 shall apply in full force and effect for only twelve (12) months from the Termination Date. 

(b) In the event that Employee terminates his employment with the Employer without Cause during the term hereof (which shall

Employee’s obligations under Sections 4 and 5 hereof shall survive in full force and effect the termination of the Agreement pursuant to this Section 13(b). 

14. Termination Upon a Change in Control. In the event of termination by Employee for Good Reason or Termination by the Employer without

force and effect his termination of employment pursuant to this Section 14. 
 (a) For purposes of this Agreement, a
Change in Control means the occurrence of any of the following events, provided that references to the Company in this Section 14(a) shall be treated as a reference solely to EGI-AM Holdings, L.L.C. 

  
 -6- 













 (1) An acquisition (other than directly from the Company) of any voting
securities of the Company (the “Voting Securities”) by any “Person” (as that term is used for purposes of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”)), immediately after which such Person has “Beneficial Ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of more than fifty percent (50%) of the combined voting power of the
Company’s then outstanding Voting Securities; provided, however, in determining whether a Change in Control has occurred, Voting Securities which are acquired in a Non-Control Acquisition shall not constitute an acquisition which would cause a
Change in Control. A “Non-Control Acquisition” shall mean an acquisition by (i) an employee benefit plan (or a trust forming a part thereof) maintained by (A) the Company, or (B) any corporation or other Person of
which a majority of its voting power or its voting equity securities or equity interest is owned, directly or indirectly, by the Company (for purposes of this definition, a “Subsidiary”), (ii) the Company or its Subsidiaries,
or (iii) any person in connection with a Non-Control Transaction (as hereinafter defined); or 
 (2) Consummation of:

 (i) A merger, consolidation or reorganization involving the Company, unless such merger, consolidation or reorganization
is a Non-Control Transaction. A “Non-Control Transaction” shall mean a merger, consolidation or reorganization of the Company where the holders of the Voting Securities of the Company, immediately before such merger, consolidation
or reorganization, own, directly or indirectly, immediately following such merger, consolidation or reorganization, more than fifty percent (50%) of the combined voting power of the outstanding Voting Securities of the entity resulting from
such merger or consolidation or reorganization (the “Surviving Entity”) in substantially the same proportion as their own ownership of the Voting Securities immediately before such merger, consolidation or reorganization; 

(ii) A complete liquidation or dissolution of the Company; or 

(iii) The sale or other disposition of all or substantially all of the assets of the Company to any Person (other than a
transfer to (x) a Subsidiary or (y) any Principal or Related Party of a Principal). 
 (3) Notwithstanding the
foregoing, (i) a Change in Control shall not be deemed to occur solely because any Person (the “Subject Person”) acquired Beneficial Ownership of more than the permitted amount of the then outstanding Voting Securities as a
result of the acquisition of Voting Securities by the Company which, by reducing the number of Voting Securities then outstanding, increases the proportional number of shares Beneficially Owned by the Subject Person, provided that if a Change in
Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Company, and after such share acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional
voting Securities which increases the percentage of the then outstanding Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall occur, and (ii) a Change in Control shall not be deemed to occur for purposes of
this Section 14 in connection with the consummation or shareholder approval of (A) any of the transactions contemplated by that certain Purchase and Sale Agreement, by and among AHS Medical Holdings LLC, Ardent Medical Services, Inc. and
Ventas, Inc., dated as of March 27, 2015, or (B) any “Pre-Closing Opco Sale” or any “Post-Closing Opco Sale” (as each such term is defined in the Commitment and Cooperation Agreement, dated as of March 27, 2015, by
and among Ventas, Inc., Employee and the other parties thereto). 

  
 -7- 













 For purposes of this Section 14, the following defined terms have the following
meanings: 
 “Principals” means Equity Group Investments (“EGI”) and any investment fund under common
control or management with EGI, and any general partner or other entity directly controlling or managing any person in EGI. 

“Related Party” means: 

(1) any controlling stockholder, partner, member, eighty percent (80%) (or more) owned Subsidiary, or immediate family
member (in the case of an individual) of any Principal; or 
 (2) any trust, corporation, partnership or other entity, the
beneficiaries, stockholders, partners, owners or persons beneficially holding an eighty percent (80%) or more controlling interest of which consist of any one or more Principals and/or such other persons referred to in the immediately preceding
clause (1). 
 (b) Severance Amount. Subject to Employee’s delivery and non-revocation of a separation and
release in the form attached hereto as Exhibit A (a “General Release”), Employee shall receive as severance benefits under this Section 14 equal to three (3) times (a) the highest salary in effect for Employee
at any time during the Term of this Agreement; (b) the highest bonus level that would be payable to Employee if bonus plan targets were achieved, regardless of actual achievement of those targets; and (c) fifteen percent (15%) of
Employee’s yearly salary at the time of the termination as the estimated value of the yearly fringe benefits described in Section 3(a)(3). Employee shall also be entitled to receive reasonable attorney’s fees and costs incurred in
making a successful claim for compensation and benefits hereunder, including all costs of arbitration, mediation, or litigation, if necessary, whenever such fees or costs are incurred, provided that the amount of expenses eligible for payment or
reimbursement during one taxable year may not affect the expenses eligible to be paid or reimbursed in any other taxable year, and provided further that the payment or reimbursement is made on or before the last day of the year following the year in
which the expense was incurred. 
 (c) Schedule of Payments. The Employer will make the severance benefit payments
described in the first sentence of Section 14(b) at the time and in the manner described Section 14(c)(1) or (2), as applicable. The amounts described in the last sentence of Section 14(b) will be paid or reimbursed promptly upon
submission of receipts or other evidence of such eligible expenses, but no later than the last day of the year following the year in which the expense was incurred. 

(1) All cash payments under Section 14 (other than pursuant to the immediately preceding sentence) will be paid in
substantially equal installments over twenty-four (24) months. The foregoing cash payments shall be payable on each regular payroll date in the twenty-four (24) month period beginning on the first regular payroll date that occurs following
the Termination Date, provided that the Employer may commence such cash payments on the first regular payroll date following the date on which the Release first becomes irrevocable. In the event any stock of the Employer is publicly traded on an
established securities market or otherwise, payment to any “specified employee”, as defined under Section 409A(a)(2)(B)(i) of the Code, of any amounts considered to be deferred compensation under Section 409A of the Code shall
not commence until six (6) months following the Termination Date. 

  
 -8- 













 (2) In the event of the death of Employee prior to the payment of all cash
due under this Section, all remaining payments will be made in a single sum to Employee’s surviving spouse within ninety (90) days after Employee’s death. If Employee is not married at the time of death, such cash payments may be made
to Employee’s estate. 
 15. Disability of Employee. In the event Employee’s employment with the Employer terminates on
account of the Employee’s Disability (as hereinafter defined), the Employer shall pay Employee at the rate of salary Employee was entitled to receive on the payroll date immediately preceding his Disability on each regular payroll date
occurring within the six (6) month period after his Termination Date. In addition, the Employer will pay Employee all unpaid salary, bonus, awards and other benefits and reimbursements of expenses incurred or earned before the Employee’s
Disability within ninety (90) days after the Termination Date. During the period in which Employee is entitled to payment under this Section 15, for so long as Employee is physically and mentally able to do so, Employee will furnish
information and assistance to the Employer. The term “Disability” shall mean the inability of Employee to perform the duties of his employment due to physical or emotional incapacity or illness (including, without limitation, alcohol or
chemical dependency), where such inability has continued or is expected to continue for more than one hundred eighty (180) days in any one (1) year period. In the event of a dispute, the determination of Disability shall be made as
follows: the Employer and Employee (or his executor or personal representative, as the case may be) shall each appoint a physician competent in the field of medicine to which such incapacity or illness relates, and the two (2) physicians so
selected shall select a third physician who shall be similarly competent. The decision of a majority of such physicians as to the Disability of Employee shall be binding on the parties hereto. 

16. Assignment. 

(a) The rights and benefits of Employee under this Agreement, other than accrued and unpaid amounts due under Section 3(a)
hereof, are personal to him and shall not be assignable. Discharge of Employee’s undertakings in Section 4(c) hereof shall be an obligation of Employee’s executors, administrators, or other legal representatives or heirs. 

(b) This Agreement may not be assigned by the Employer except to an affiliate of the Employer, provided, however, that if the
Employer shall merge or effect a share exchange with or into, or sell or otherwise transfer substantially all its assets to, another corporation, the Employer may assign its rights hereunder to that corporation. 

17. Notices. Any notice or other communications under this Agreement shall be in writing, signed by the party making same, and shall be
delivered personally or sent by overnight courier, certified or registered mail, postage prepaid, addressed as follows:

 (iv) claims against any Released Party for violation of the federal or any state constitution,

(c) Age Discrimination In Employment Act Release. In accordance with the Older Workers Benefit Protection Act of 1990, the Executive
acknowledges and agrees that the Claims include a waiver of all rights and release of all claims that the Executive may have against any Released Party under the Age Discrimination in Employment Act of 1967 (“ADEA”), other than
claims that may arise after the date of this Separation Agreement (with the understanding that any claim that the Executive may have based on the Executive’s separation from employment by the Company on the Separation Date arose before the
execution of this Separation Agreement), and that such waiver and release is knowingly and voluntarily made. The Executive acknowledges that the consideration given for this waiver and release is in addition to anything of value to which the
Executive was already entitled. The Executive further acknowledges that: 
 (i) the Executive was advised, and is hereby again advised in
writing, to consult with independent legal counsel of the Executive’s choice before executing this Separation Agreement concerning its meaning and application, 

(ii) the Executive is entitled to at least [twenty-one / forty-five] calendar days to review and consider the release contemplated by
Section 2(b)(iii) and this Section 2(c) of Claims arising from or related to the ADEA, and, if the Executive executes this Separation Agreement before the expiration of such review period, then the Executive hereby freely and
voluntarily waives the remaining time period allotted under applicable law for considering a release of ADEA claims, 
 (iii) the Executive
has seven calendar days after executing this Separation Agreement to revoke the release under Section 2(b)(iii) and this Section 2(c) of Claims arising from or related to the ADEA and the release of such Claims will not be
effective until that revocation period has expired, and 
 (iv) nothing in this Separation Agreement prevents or precludes the Executive
from challenging or seeking a determination in good faith of the validity of the Executive’s waiver of rights and claims under the ADEA, and this Separation Agreement does not impose any condition precedent, penalties or costs for doing so,
unless specifically authorized by federal law. 












 (d) Covenant Not to Sue. The Executive will not bring, continue or maintain any claim
or legal proceeding against any Released Party before any court or other judicial or arbitral forum by reason of any Claims released by this Separation Agreement. Although the Executive may file a charge with state or federal agencies, the Executive
agrees not to see or accept any money damages or other relief upon the filing of any such administrative charges or complaints or in judicial proceedings arising therefrom. If any court, administrative agency or other forum assumes jurisdiction over
any complaint or claim against any Released Party released by this Separation Agreement, then the Executive will, and will cause the Executive’s affiliates to, promptly direct such court, agency or forum to withdraw from or dismiss the matter
with prejudice. If the Executive or any of the Executive’s affiliates violates this Separation Agreement by suing a Released Party, then the Executive will pay all costs and expenses (including reasonable attorney’s fees and costs)
incurred by such Released Party in defending against such suit. 
 (e) Compliance. The Executive acknowledges and agrees that neither
this Separation Agreement nor performance hereunder constitutes an admission by any Released Party of any violation of any federal, state or local law (including common law) or rules or regulations promulgated thereunder, breach of any contract or
any other wrongdoing. Except as previously disclosed to the Company, the Executive has no knowledge of any violation of any applicable federal, state or local law (including common law), or rules or regulations promulgated thereunder, by any
Released Party and further agrees that the Executive will not and will not permit the Executive’s affiliates to bring any “qui tarn” or whistleblower action against any Released Party after the date of this Separation Agreement. Any
monetary reward received by the Executive or the Executive’s affiliates in any “qui tam” or whistleblower action against any Released Party after the date of this Separation Agreement will be donated to an organization exempt from
federal income tax purposes under Code Section 501(c)(3), the charitable purpose of which is to provide health care to a broad cross-section of the community served by the organization. 

(f) No Assignment or Transfer of Claims. The Executive represents that the Executive has not assigned or otherwise transferred any
Claim. 
 (g) Acknowledgements and Agreements of the Executive. In signing this Separation Agreement, the Executive acknowledges and
agrees that: 
 (i) this Separation Agreement will be effective as a bar to all Claims released by this Separation Agreement, 

(ii) this Separation Agreement will be given full force and effect according to its terms, including those relating to unknown and unsuspected
Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected or unanticipated Claims) and those relating to any other Claims, and that this waiver is an essential and material term of
this Separation Agreement because without such waiver the Company would not have agreed to make certain payments to the Executive as contemplated by this Separation Agreement, 

(iii) if the Executive asserts any Claim seeking damages against any of the Released Parties, then this Separation Agreement will be a
complete defense to such Claim, 
 (iv) no Claim currently exists and the Executive is not aware of any pending or threatened Claim, 

(v) neither the release of Claims under this Separation Agreement nor the furnishing of the consideration therefor will be deemed or construed
to be an admission by any Released Party or the Executive of any improper or unlawful conduct, and 












 (vi) after the date of this Separation Agreement, the Executive may discover facts
different from or in addition to those now known or believed to be true regarding the subject matter of the Claims released by this Separation Agreement, but this Separation Agreement will remain in full force and effect, notwithstanding the
existence of any different or additional facts. 
 (h) Further Acknowledgements and Agreements of Executive. In connection with
signing this Separation Agreement, the Executive acknowledges, understands and agrees that: 
 (i) the Executive has carefully read and
fully understands all of the terms of this Separation Agreement and has had the opportunity to discuss the same and their consequences with independent legal counsel, 

(ii) the Executive is, through this Separation Agreement, releasing the Released Parties from any and all Claims that the Executive may have
against the Released Parties, 
 (iii) the Executive knowingly and voluntarily agrees to all of the terms of this Separation Agreement, 

(iv) the Executive knowingly and voluntarily intends to be legally bound by all of the terms of this Separation Agreement, and

choice before executing this Separation Agreement concerning its meaning and application.

or terms of this Separation Agreement; provided that the Executive may disclose the terms of this Separation Agreement (a) to the extent required to enforce or comply with the terms of this Separation Agreement (including the restrictive
covenants), (b) to the extent required to be disclosed by any law or order (provided that as soon as practicable before such disclosure, the Executive will give the Company prompt written notice of such disclosure to enable the Company
to seek a protective order or otherwise preserve the confidentiality of such information), (c) to the Executive’s immediate family members and representatives (such as tax advisors and attorneys) who need to know such information for
legitimate business purposes and (d) in the course of filing a charge with a government agency or participating in its investigation. If the Executive is asked for information concerning this Separation Agreement, the Executive will state only
