stock options granted in accordance with Section 422 of the Internal Revenue Code, after termination of Employee’s employment under this Agreement for any reason other than pursuant to Section 4.1, Employee shall be allowed a period
of one hundred eighty (180) days during which to exercise any vested options to purchase Mednax’s common stock or vested stock appreciation rights and realize

  

 8 








 
any other vested incentive compensation awards that may be granted or made under any Equity Plan; provided, however, that in no event shall the period during which Employee may exercise any
vested stock option or vested stock appreciation right and realize any other vested incentive compensation awards that may be granted or made under any Equity Plan be extended pursuant to this Section 5.10 to a date that is later than the

defined above) occurs within the twelve (12) month period of a Change in Control, any unvested stock options, any unvested stock appreciation rights and any other unvested incentive compensation awards held by Employee on the termination date
shall fully vest and, in the case of stock options, become immediately exercisable. 
 5.11. Performance Bonus. In the
situations described in Sections 5.2, 5.3, 5.4 and 5.5 and in the situations described in Section 5.7 with regard to the termination of Employee’s employment pursuant to Sections 4.7(a), (b), (d), (e), (f) and (g), upon termination of
this Agreement, Employee may be paid, solely in consideration of services rendered by Employee prior to termination, a bonus with respect to Employer’s fiscal year in which the termination date occurs, equal to the Performance Bonus, if any,
that would have been payable to Employee, based on Employee and Employer meeting certain goals and objectives, for the fiscal year if Employee’s employment had not been terminated, multiplied by the number of days in the fiscal year prior to
and including the date of termination and divided by three hundred sixty five (365). In the situation described in Section 5.7 with regard to the termination of Employee’s employment pursuant to Section 4.7(c), upon termination of
this Agreement, Employee will be paid, solely in consideration of services rendered by Employee prior to termination, a bonus with respect to Employer’s fiscal year in which the termination date occurs, equal to the Performance Bonus, if any,
that would have been payable to Employee as if (i) Employee worked the entire fiscal year; and (ii) Employee met all goals and objectives of such year. The amount of the Post-Termination Performance Bonus shall be determined in good faith
by Employer in its sole discretion at the time that Employer distributes bonuses to similarly situated employees. Any amount payable under this Section 5.11 shall be paid to Employee when Employer pays performance bonuses to its eligible
employees, which shall be in the calendar year following the termination date of this Agreement. 
 5.12. Section 409A
Compliance. 
 (a) General. It is the intention of both Employer and Employee that the benefits and
rights to which Employee could be entitled in connection with termination of employment comply with Section 409A of the Code and the Treasury Regulations and other guidance promulgated or issued thereunder (“Section 409A”), and the
provisions of this Agreement shall be construed in a manner consistent with that intention. If Employee or Employer believes, at any time, that any such benefit or right does not so comply, it shall promptly advise the other and shall negotiate
reasonably and in good faith to amend the terms of such benefits and rights such that they comply with Section 409A of the Code (with the most limited possible economic effect on Employee and on Employer). 
  

 9 








 (b) Distributions on Account of Separation from Service. If and to
the extent required to comply with Section 409A, no payment or benefit required to be paid under this Agreement on account of termination of Employee’s employment shall be made unless and until Employee incurs a “separation from
service”, within the meaning of Section 409A. 
 (c) 6 Month Delay for Specified Employees. 

(i) If Employee is a “specified employee”, then no payment or benefit that is payable on account of
Employee’s “separation from service”, as that term is defined for purposes of Section 409A, shall be made before the date that is six months after Employee’s “separation from service” (or, if earlier, the date of
Employee’s death) if and to the extent that such payment or benefit constitutes deferred compensation (or may be nonqualified deferred compensation) under Section 409A and such deferral is required to comply with the requirements of
Section 409A. Any payment or benefit delayed by reason of the prior sentence shall be paid out or provided in a single lump sum at the end of such required delay period in order to catch up to the original payment schedule. 
 (ii) For purposes of this provision, Employee shall be considered to be a “specified employee” if, at the time of
his or her separation from service, Employee is a “key employee”, within the meaning of Section 416(i) of the Code, of Employer (or any person or entity with whom Employer would be considered a single employer under
Section 414(b) or Section 414(c) of the Code) any stock in which is publicly traded on an established securities market or otherwise. 
 (iii) Unless otherwise required to comply with Section 409A, a payment or benefit shall not be deferred pursuant to this provision if: 
 (x) it is not made on account of Employee’s “separation from service”, (y) it is
required to be paid no later than within 2 1/2
months after the end of the taxable year of Employee in which the payment or benefit is no longer subject to a “substantial risk of forfeiture”, as that term is defined for purposes of Section 409A, or (z) the payment satisfies
the following requirements: (A) it is being paid or provided due to Employer’s termination of Employee’s employment without Cause (Section 4.4) or Employee’s termination of employment after a Change in Control for the reasons set
forth in Section 4.7(c) hereof, (B) it does not exceed two times the lesser of (1) Employee’s annualized compensation from Employer for the calendar year prior to the calendar year in which the termination of Employee’s
employment occurs, and (2) the maximum amount of compensation that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which Employee’s employment terminates, and (C) the
payment is required under this Agreement to be paid no later than the last day of the second calendar year following the calendar year in which Employee incurs a “separation from service”. 
  

 10 








 (d) No Acceleration of Payments. Neither Employer nor Employee, individually
or in combination, may accelerate any payment or benefit that is subject to Section 409A, except in compliance with Section 409A and the provisions of this Agreement, and no amount shall be paid prior to the earliest date on which it may
be paid without violating Section 409A. 
 (e) Treatment of Each Installment as a Separate Payment. For
purposes of applying the provisions of Section 409A to this Agreement, each separately identified amount to which Employee is entitled under this Agreement shall be treated as a separate payment. In addition, to the extent permissible under
Section 409A, any series of installment payments under this Agreement shall be treated as a right to a series of separate payments. 
 (f) Reimbursements and In-Kind Benefits. 
 (i) Any reimbursements
by Employer to Employee of any eligible expenses pursuant to this Agreement that are not excludible from Employee’s income for Federal income tax purposes (“Taxable Reimbursements”) shall be made on or before the last day of the
taxable year of Employee following the year in which the expense was incurred. 
 (ii) The amount of any Taxable
Reimbursements, and the value of any in-kind benefits to be provided to Employee under this Agreement, during any taxable year of Employee shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other
taxable year of Employee. 
 (iii) The right to Taxable Reimbursements, or in-kind benefits, shall not be subject
to liquidation or exchange for another benefit. 
 5.13. Release. Employer shall provide Employee with a general release
in the form attached as Exhibit B (subject to such modifications as Employer may reasonably request) within seven (7) days after Employee’s termination date. Payments or benefits to which Employee may be entitled pursuant to this
Article 5 (other than any accrued but unpaid Base Salary and employee benefits as of the end of the Employment Period) (the “Severance Amounts”) shall be conditioned upon Employee executing the general release within 21 days after
receiving it from Employer and the general release becoming irrevocable upon the expiration of 7 days following the Employee’s execution of it. Payment of the Severance Amounts shall be suspended during the period (the “Suspension
Period”) that begins on Employee’s termination date and ends on the date (“Suspension Termination Date”) that is thirty-five (35) days after Employee’s termination date; provided, however, that this suspension shall not
apply, and Employer shall be required to provide, any continued health insurance coverage that would be required under Article 5.9 hereof during the Suspension Period. If Employee executes the general release and the general release becomes
irrevocable by no later than the Suspension Termination Date, then payment of any Severance Amounts that were suspended pursuant to this provision shall be made in the first payroll period that follows the Suspension Termination Date, and any
Severance Amounts that are payable after the Suspension Termination Date shall be paid at the times provided in Article 5.

 6. Successors; Binding Agreement. 
 6.1. Successors. Employer shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise)
acquiring a majority of Employer’s voting common stock or any other successor to all or substantially all of the business and/or assets of Employer to expressly assume and agree to perform this Agreement in the same manner and to the same
extent that Employer would be required to perform it if no such succession had taken place and Employee hereby consents to any such assignment. In such event, “Employer” shall mean Employer as previously defined and any successor to its
business and/or assets which executes and delivers the agreement provided for in this Section 6 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. This Section shall not limit Employee’s
ability to terminate this Agreement in the circumstances described in Section 4.7(c) in the event of a Change in Control of Employer. 
 6.2. Benefit. This Agreement and all rights of Employee under this Agreement shall inure to the benefit of and be enforceable by Employee’s personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If Employee should die after the termination date and amounts would have been payable to Employee under this Agreement if Employee had continued to live, including under
Section 5 hereof, then such amounts shall be paid to Employee’s devisee, legatee, or other designee or, if there is no such designee, Employee’s estate. 
 7. Conflicts with Prior Employment Contract. Except as otherwise provided in this Agreement, this Agreement constitutes the entire agreement among the parties pertaining to the subject matter
hereof, and supersedes and revokes any and all prior or existing agreements, written or oral, relating to the subject matter hereof, and this Agreement shall be solely determinative of the subject matter hereof. 
 8. Restrictive Covenants; Confidential Information; Work Product; Injunctive Relief. 
 8.1. No Material Competition. Employer and Employee acknowledge and agree that a strong relationship and connection exists between
Employer and its current and prospective patients, referral sources, and customers as well as the hospitals and healthcare facilities at which it provides professional services. Employer and Employee further acknowledge and agree that the
restrictive covenants described in this Section are designed to enforce, and are ancillary to or part of, the promises contained in this Agreement and are reasonably necessary to protect the legitimate interests of Employer in the following:
(1) the use and disclosure of the Confidential Information as described in Section 8.4; (2) the professional development activities described in Section 1.2; and (3) the goodwill of the Employer, as promoted by Employee as
provided in Section 1.2. The foregoing listing is by way of example only and shall not be construed to be an exclusive or exhaustive list of such interests. Employee acknowledges that the restrictive covenants set forth below are of significant
value to Employer and were a material inducement to Employer in agreeing to the terms of this Agreement. Employee further acknowledges that the goodwill and other proprietary interest of Employer will suffer irreparable and continuing damage in the
event Employee enters into competition with Employer in violation of this Section.

 (a) Employer’s Business. Therefore, Employee agrees that, except
with respect to services performed under this Agreement on behalf of Employer, Employee shall not, at any time during the Restricted Period (as defined below), for Employee or on behalf of any other person, persons, firm, partnership,
corporation or employer, participate or engage in or own an interest in, directly or indirectly, any individual proprietorship, partnership, corporation, joint venture, trust or other form of business entity, whether as an individual proprietor,
partner, joint venturer, officer, director, member, employee, consultant, independent contractor, stockholder, lender, landlord, finder, agent, broker, trustee, or in any manner whatsoever, if such entity or its affiliates is engaged in, directly or
indirectly, “Employer’s Business,” as defined on Exhibit A hereto. Employee acknowledges that, as of the date hereof, Employee’s responsibilities will include matters affecting the businesses of Employer listed on Exhibit A. For
purposes of this Section 8, the “Restricted Period” shall mean the Employment Period plus (i) twelve (12) months in the event this Agreement is terminated pursuant to Sections 4.1 (a), 4.1 (b), 4.1 (c), 4.1 (d), 4.7(a),
4.7(b), 4.7(d), 4.7(e), 4.7(f) or 4.7(g) or (ii) eighteen months in the event the Agreement is terminated for any other reason. 
 8.2. No Hire. Employee further agrees that Employee shall not, at any time during the Employment Period and for a period of eighteen (18) months immediately following termination of this Agreement for any reason, for
Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, employ, or knowingly permit any company or business directly or indirectly controlled by Employee to employ or otherwise engage (a) any person who
is a then current employee or independent contractor of Employer or one of its affiliates, or (b) any person who was an employee or independent contractor of Employer or one of its affiliates in the prior six (6) month period, or in any
manner seek to induce such persons to leave his or her employment or engagement with Employer or one of its affiliates (including without limitation for or on behalf of a subsequent employer of Employee). 
 8.3 Non-solicitation. Employee further agrees that Employee shall not, at any time during the Employment Period and for a
period of eighteen (18) months immediately following termination of this Agreement for any reason, for Employee or on behalf of any other person, persons, firm, partnership, corporation or employer, solicit or accept business from or take any
action that would interfere with, diminish or impair the valuable relationships that Employer or its affiliates have with (i) hospitals or other health care facilities with which Employer or its affiliates have contracts to render professional
services or otherwise have established contractual relationships, (ii) patients, (iii) referral sources, (iv) vendors, (v) any other clients of Employer or its affiliates, (vi) prospective hospitals, patients, referral
sources, vendors or clients whose business Employee was aware that Employer or any affiliate of Employer was in the process of soliciting at the time of Employee’s termination (including potential acquisition targets), or (vii) hospitals,
patients, referral sources, vendors or clients with which Employer had been doing business within one (1) year prior to Employee’s termination. 
  

 13 








 8.4. Confidential Information. At all times during the term of this Agreement,
Employer shall provide Employee with access to “Confidential Information.” As used in this Agreement, the term “Confidential Information” means any and all confidential, proprietary or trade secret information, whether disclosed,
directly or indirectly, verbally, in writing or by any other means in tangible or intangible form, including that which is conceived or developed by Employee, applicable to or in any way related to: (i) patients with whom Employer has a
physician/patient relationship; (ii) the present or future business of Employer; or (iii) the research and development of Employer. Without limiting the generality of the foregoing, Confidential Information includes: (a) the
development and operation of Employer’s medical practices, including information relating to budgeting, staffing needs, marketing, research, hospital relationships, equipment capabilities, and other information concerning such facilities and
operations and specifically including the procedures and business plans developed by Employer for use at the hospitals where Employer conducts its business; (b) contractual arrangements between the Employer and insurers or managed care
associations or other payors; (c) the databases of Employer; (d) the clinical and research protocols of Employer, including coding guidelines; (e) the referral sources of Employer; (f) other confidential information of Employer
that is not generally known to the public that gives Employer the opportunity to obtain an advantage over competitors who do not know or use it, including the names, addresses, telephone numbers or special needs of any of its patients, its patient
lists, its marketing methods and related data, lists or other written records used in Employer’s business, compensation paid to employees and other terms of employment, accounting ledgers and financial statements, contracts and licenses,
business systems, business plan and projections, and computer programs. The parties agree that, as between them, this Confidential Information constitutes important, material, and confidential trade secrets that affect the successful conduct of
Employer’s business and its goodwill. Employer acknowledges that the Confidential Information specifically enumerated above is special and unique information and is not information that would be considered a part of the general knowledge and
skill Employee has or might otherwise obtain. 
 Notwithstanding the foregoing, Confidential Information shall not include any
information that (i) was known by Employee from a third party source before disclosure by or on behalf of Employer, (ii) becomes available to Employee from a source other than Employer that is not, to Employee’s knowledge, bound by a
duty of confidentiality to Employer, (iii) becomes generally available or known in the industry other than as a result of its disclosure by Employee, (iv) has been independently developed by Employee and may be disclosed by Employee
without breach of this Agreement, or (v) is disclosed pursuant to a requirement or a request of a court, arbitration panel or governmental authority, or required by operation of law, provided, in each case, that the Employee shall bear the
burden of demonstrating that the information falls under one of the above-described exceptions. 
 Employee agrees that the
terms of this Agreement shall be deemed Confidential Information for purposes of this Section. Employee shall keep the terms of this Agreement strictly confidential and will not, without the prior written consent of Employer, disclose the details of
this Agreement to any third party in any manner whatsoever in whole or in part, with the exception of Employee’s representatives (such as tax advisors and attorneys) who need to know such information. 
 Employee agrees that Employee will not at any time, whether during or subsequent to the term of Employee’s employment with Employer, in
any fashion, form or manner, unless

  

 14 








 
specifically consented to in writing by Employer or unless otherwise related to her performance of her duties as an employee or Employer, either directly or indirectly, use or divulge, disclose,
or communicate to any person, firm or corporation, in any manner whatsoever, any Confidential Information of any kind, nature, or description, subject to applicable law. The parties agree that any breach by Employee of any term of this Section is a
material breach of this Agreement and shall constitute “cause” for the termination of Employee’s employment hereunder. In the event that Employee is ordered to disclose any Confidential Information, whether in a legal or a regulatory
proceeding or otherwise, Employee shall provide Employer with prompt written notice of such request or order so that Employer may seek to prevent disclosure or, if that cannot be achieved, the entry of a protective order or other appropriate
protective device or procedure in order to assure, to the extent practicable, compliance with the provisions of this Agreement. In the case of any disclosure required by law, Employee shall disclose only that portion of the Confidential Information
that Employee is ordered to disclose in a legally binding subpoena, demand or similar order issued pursuant to a legal or regulatory proceeding. 
 All Confidential Information, and all equipment, notebooks, documents, memoranda, reports, files, samples, books, correspondence, lists, other written and graphic records, in any media (including
electronic or video) containing Confidential Information or relating to the business of Employer, which Employee shall prepare, use, construct, observe, possess, or control shall be and remain Employer’s sole property (collectively
“Employer Property”). Upon termination or expiration of this Agreement, or earlier upon Employer’s request, Employee shall promptly deliver to Employer all, and not take with Employee any, Employer Property. 
 8.5. Ownership of Work Product. Employee agrees and acknowledges that (i) all copyrights, patents, trade secrets, trademarks,
service marks, or other intellectual property or proprietary rights associated with any ideas, concepts, techniques, inventions, processes, or works of authorship developed or created by Employee during the course of performing work for Employer and
any other work product conceived, created, designed, developed or contributed by Employee during the term of this Agreement that relates in any way to Employer’s Business (collectively, the “Work Product”), shall belong exclusively to
Employer and shall, to the extent possible, be considered a work made for hire within the meaning of Title 17 of the United States Code. To the extent the Work Product may not be considered a work made for hire owned exclusively by Employer,
Employee hereby assigns to Employer all right, title, and interest worldwide in and to such Work Product at the time of its creation, without any requirement of further consideration. Upon request of Employer, Employee shall take such further
actions and execute such further documents as Employer may deem necessary or desirable to further the purposes of this Agreement, including without limitation separate assignments of all right, title, and interest in and to all rights of copyright
and all right, title, and interest in and to any inventions or patents and any reissues or extensions which may be granted therefore, and in and to any improvements, additions to, or modifications thereto, which Employee may acquire by invention or
otherwise, the same to be held and enjoyed by Employer for its own use and benefit, and for the use and benefit of Employer’s successors and assigns, as fully and as entirely as the same might be held by Employee had this assignment not been
made. 
  

 15 








 8.6. Clearance Procedure for Proprietary Rights Not Claimed by Employer. In the event
that Employee wishes to create or develop, other than on Employer’s time or using Employer’s resources, anything that may be considered Work Product but to which Employee believes Employee should be entitled to the personal benefit
of, Employee agrees to follow the clearance procedure set forth in this Section. Before beginning any such work, Employee agrees to give Employer advance written notice and provide Employer with a sufficiently detailed written description of the
work under consideration for Employer to make a determination regarding the work. Unless otherwise agreed in a writing signed by Employer prior to receipt, Employer shall have no obligation of confidentiality with respect to such request or
description. Employer will determine in its sole discretion, within thirty (30) days after Employee has fully disclosed such plans to Employer, whether rights in such work will be claimed by Employer. If Employer determines that it does not
claim rights in such work, Employer agrees to so notify Employee in writing and Employee may retain ownership of the work to the extent that such work has been expressly disclosed to Employer. Employee agrees to submit for further review any
significant improvement, modification, or adaptation that could reasonably be related to Employer’s Business so that it can be determined whether the improvement, modification, or adaptation relates to the business or interests of Employer.
Clearance under this procedure does not relieve Employee of the restrictive covenants set forth in this Section 8. 
 8.7.
Non-Disparagement. For a period of ten (10) years after the termination of this Agreement, Employee will not, directly or indirectly, as an individual or on behalf of a firm, corporation, partnership or other legal entity, make any
disparaging or negative comment to any other person or entity regarding Employer or any of its affiliates, agents, attorneys, employees, officers and directors, Employee’s work conditions or circumstances surrounding Employee’s separation
from Employer or otherwise impugn or criticize the name or reputation of Employer, its affiliates, agents, attorneys, employees, officers or directors, orally or in writing. 
 8.8. Review by Employee. Employee has carefully read and considered the terms and provisions of this Section 8, and having
done so, agrees that the restrictions set forth in this Section 8 are fair and reasonably required for the protection of the interests of Employer. In the event that any term or provision set forth in this Section 8 shall be held to be
invalid or unenforceable by a court of competent jurisdiction, the parties hereto agree that such invalid or unenforceable term(s) or provision(s) may be severed from this Agreement without, in any manner, affecting the remaining portions hereof.
Without limiting other possible remedies available to Employer, Employee agrees that injunctive or other equitable relief will be available to enforce the covenants set forth in this Section, such relief to be without the necessity of posting a
bond. In the event that, notwithstanding the foregoing, any part of the covenants set forth in this Section shall be held to be invalid, overbroad, or unenforceable by an arbitration panel or a court of competent jurisdiction, the parties hereto
agree that such invalid, overbroad, or unenforceable provision(s) may be modified or severed from this Agreement without, in any manner, affecting the remaining portions of this Section 8 (all of which shall remain in full force and effect). In
the event that any provision of this Section 8 related to time period or areas of restriction shall be declared by an arbitration panel or a court of competent jurisdiction to exceed the maximum time period, area or activities such arbitration
panel or court deems reasonable and enforceable, said time period or areas of restriction shall be deemed modified to the minimum extent necessary to make the geographic or temporal restrictions or activities reasonable and enforceable. 

 

 16 








 8.9. Survival. The provisions of this Section 8 shall survive the termination of
this Agreement and Employee’s employment with Employer. The provisions of this Section 8 shall apply during the time Employee is receiving Disability payments from Employer as a result of a termination of this Agreement pursuant to
Section 4.2 hereof. In the event of a breach of this Section 8 by Employee, Employer retains the right to terminate any continuing payments to Employee provided for in Section 5 of this Agreement. The provisions of this
Section 8 are expressly intended to benefit and be enforceable by other affiliated entities of Employer, who are express third party beneficiaries hereof. Employee shall not assist others in engaging in any of the activities described in the
foregoing restrictive covenants. 
 9. Arbitration. Any controversy or claim arising out of or relating to this
Agreement, or any alleged breach hereof shall be finally determined by binding arbitration before a three member panel, consisting of one member selected by each party hereto, with the third member selected by the first two arbitrators. Each party
hereto shall bear the costs of its own nominee, and shall share equally the cost of the third arbitrator and the parties agree that the costs of arbitration shall not be subject to reapportionment by the arbitration panel. The arbitration
proceedings shall be held in Sunrise, Florida, unless otherwise mutually agreed by the parties, and shall be conducted in accordance with the American Health Lawyer’s Association Dispute Resolution Service, Rules of Procedure for Arbitration.
Judgment on the award rendered by the arbitration panel may be entered and enforced by any court having jurisdiction thereof. Notwithstanding anything herein to the contrary, if the Employer shall require immediate injunctive relief, then the
Employer shall be entitled to seek such relief in any court having jurisdiction, and if the Employer elects to do so, the Employee hereby consents to the jurisdiction of the state and federal courts sitting in the State of Florida and to the
applicable service of process. Employee hereby waives and agrees not to assert, to the fullest extent permitted by applicable law, any claim that (i) Employee is not subject to the jurisdiction of such courts, (ii) Employee is immune from
any legal process issued by such courts and (iii) any litigation or other proceeding commenced in such courts is brought in an inconvenient forum. Any such arbitration shall be treated as confidential by all parties thereto, except as otherwise
provided by law or as otherwise necessary to enforce any judgment or order issued by the arbitrators. 
 10. Governing
Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida without regard to its conflict of laws principles to the extent that such principles would require the application of laws other than the
laws of the State of Florida. 
 11. Notices. Any notice required or permitted to be given under this Agreement shall be
in writing and shall be deemed to have been given when delivered by hand or when deposited in the United States mail by registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

 or to such other addresses as either party hereto may from time to time give notice of to the other in the
aforesaid manner. 
 12. Benefits: Binding Effect. This Agreement shall be for the benefit of and binding upon the
parties hereto and their respective heirs, personal representatives, legal representatives, successors and, where applicable, assigns. Notwithstanding the foregoing, Employee may not assign the rights or benefits hereunder without the prior written
consent of Employer. 
 13. Severability. The invalidity of any one or more of the words, phrases, sentences, clauses or
sections contained in this Agreement shall not affect the enforceability of the remaining portions of this Agreement or any part thereof, all of which are inserted conditionally on their being valid in law, and, in the event that any one or more of
the words, phrases, sentences, clauses or sections contained in this Agreement shall be declared invalid, this Agreement shall be construed as if such invalid word or words, phrase or phrases, sentence or sentences, clause or clauses, or section or
sections had not been inserted. If such invalidity is caused by length of time or size of area, or both, the otherwise invalid provision will be considered to be reduced to a period or area, which would cure such invalidity. 
 14. Waivers. The waiver by either party hereto of a breach or violation of any term or provision of this Agreement shall not operate
nor be construed as a waiver of any subsequent breach or violation. 
 15. Damages. Nothing contained herein shall be
construed to prevent Employer or Employee from seeking and recovering from the other damages sustained by either or both of them as a result of a breach of any term or provision of this Agreement. In the event that either party hereto brings suit
for the collection of any damages resulting from, or the injunction of any action constituting, a breach of any of the terms or provisions of this Agreement, then the party found to be at fault shall pay all reasonable court costs and
attorneys’ fees of the other, whether such costs and fees are incurred in a court of original jurisdiction or one or more courts of appellate jurisdiction. 
 16. No Third Party Beneficiary. Except as provided in Section 8.9, nothing expressed or implied in this Agreement is intended, or shall be construed, to confer upon or give any person (other
than the parties hereto and, in the case of Employee, Employee’s heirs, personal representative(s) and/or legal representative) any rights or remedies under or by reason of this Agreement. No agreements or representations, oral or otherwise,
express or implied, have been made by either party with respect to the subject matter of this Agreement which agreements or representations are not set forth expressly in this Agreement, and this Agreement supersedes any other employment agreement
between Employer and Employee.

 EXHIBIT A 
 BUSINESS OF EMPLOYER 
 As of the date hereof,
Employer, directly or through its affiliates, provides professional medical services and all aspects of practice management services in medical practice areas that include, but are not limited to, the following (collectively referred to herein as
“Employer’s Business”): 
 (1) Neonatology, including hospital well baby care; 
 (2) Maternal-Fetal Medicine, including general obstetrics services; 
 (3) Pediatric Cardiology; 
 (4) Pediatric Intensive Care, including Pediatric Hospitalist Care;

 (5) Newborn hearing screening services; and 
 (6) Anesthesiology. 
 References to Employer’s Business in this Agreement shall include such other medical
service lines, practice management services and other businesses entered into by Employer after the date hereof but during the term of this Agreement; provided, that to be considered a part of Employer’s Business, Employer must have
engaged in such other service line, practice management service or other business at least six (6) months prior to the termination date of this Agreement. For purposes of this Exhibit A, businesses of Employer shall include the businesses
conducted by Employer’s subsidiaries, entities under common control and affiliates as defined under Rule 144 of the Securities Act of 1933, as amended. Such affiliates shall include the professional corporations and associations whose operating
results are consolidated with Employer for financial reporting purposes. 
 Notwithstanding the foregoing, Employer acknowledges
and agrees to the following exceptions and clarifications regarding the scope of Employer’s Business. 
 A. Practice
Management Services. Employer acknowledges that, as of the date hereof, Employer’s Business relates to the delivery of both professional and practice management services in the forgoing practice areas. Therefore, as of the date hereof,
Employer acknowledges that it would not be a violation of Section 8.1 of the Agreement for Employee to provide services to a practice management company (such as a billing company or management services organization (MSO)) if such practice
management company is not owned by, affiliated with (as defined under Rule 144 of the Securities Act of 1933, as amended) or under common control with a health care provider that provides services in the medical services areas included in
Employer’s Business. Subject to paragraph C below, the provisions of this paragraph shall not apply to the extent that, after the date hereof, Employer enters into a business that involves the delivery of practice management services to
unrelated third parties. 
 B. Hospital Services. Employer and Employee acknowledge that, as of the date hereof, Employer
does not currently operate hospitals, hospital systems or universities. Nevertheless, the businesses of hospitals, hospital systems and universities would be the same as Employer’s Business

  

 21 








 
where such hospitals, hospital systems or universities provide or contract with others to provide some or all of the medical services included in Employer’s Business. Therefore, the parties
desire to clarify their intent with respect to the limitations on Employee’s ability to work for or contract with others to provide services for a hospital, hospital system or university after termination of this Agreement. Section 8.1
shall not be deemed to restrict Employee’s ability to work for a hospital, hospital system or university if the hospital, hospital system or university does not provide any of the medical services included in Employer’s Business.
Furthermore, even if a hospital, hospital system or university provides medical services that are included in Employer’s Business, Employee may work for such hospital, hospital system or university if (i) Employee has no direct supervisory
responsibility for or involvement in the hospital’s, hospital system’s or university’s medical services that are Employer’s Business and (ii) Employee would not otherwise violate Section 8.1. Finally, Employer agrees
that Employee may hold direct supervisory responsibility for or be involved in the medical services of a hospital, hospital system or university that are included in Employer’s Business so long as such hospital, hospital system or university is
located at least ten (10) miles from a medical practice owned or operated by Employer or its affiliate. Subject to paragraph C below, the provisions of this paragraph shall not apply to the extent that, after the date hereof, Employer enters
into the business of operating a hospital or hospital system. 
 C. De Minimus Exception. Employer agrees that a medical
service line (other than those listed in items 1 through 5 above), practice management service or other business entered into by Employer shall not be considered to be a part of Employer’s Business if such medical service line, practice
management service or other business constitutes less than Fifteen Million Dollars ($15,000,000) of Employer’s annual revenues. 
 D. Certain Ownership Interests. It shall not be deemed to be a violation of Section 8.1 for Employee to: (i) own, directly or indirectly, five percent (5%) or less of a publicly-traded entity; or (ii) own,
directly or indirectly, any other company or entity the ownership interests of which are held through a mutual fund or other fund in which Employee has invested without specific direction of the deployment of the investable funds; or (iii) own,
directly or indirectly, less than five percent (5%) of a privately-held business or company, if Employee is at all times a passive investor with no board representation, management authority or other special rights to control operations of such
business or company.

 EXHIBIT B 
 FORM OF RELEASE 
 GENERAL RELEASE OF CLAIMS

 1.                 
(“Employee”), for himself and his family, heirs, executors, administrators, legal representatives and their respective successors and assigns, in exchange for the consideration received pursuant to Section 5 of the Employment
Agreement to which this release is attached as Exhibit B (the “Employment Agreement”), does hereby release and forever discharge Mednax Services, Inc. (“Employer”), its subsidiaries, affiliated companies, successors
and assigns, and its current or former directors, officers, employees, shareholders or agents in such capacities (collectively with Employer, the “Released Parties”) from any and all actions, causes of action, suits, controversies,
claims and demands whatsoever, for or by reason of any matter, cause or thing whatsoever, whether known or unknown including, but not limited to, all claims under any applicable laws arising under or in connection with Employee’s employment or
termination thereof, whether for tort, breach of express or implied employment contract, wrongful discharge, intentional infliction of emotional distress, or defamation or injuries incurred on the job or incurred as a result of loss of employment.
Employee acknowledges that Employer encouraged him to consult with an attorney of his choosing, and through this General Release of Claims encourages him to consult with his attorney with respect to possible claims under the Age Discrimination in
Employment Act (“ADEA”) and that he understands that the ADEA is a Federal statute that, among other things, prohibits discrimination on the basis of age in employment and employee benefits and benefit plans. Without limiting the
generality of the release provided above, Employee expressly waives any and all claims under ADEA that he may have as of the date hereof. Employee further understands that by signing this General Release of Claims he is in fact waiving, releasing
and forever giving up any claim under the ADEA as well as all other laws within the scope of this paragraph 1 that may have existed on or prior to the date hereof. Notwithstanding anything in this paragraph 1 to the contrary, this General Release of
Claims shall not apply to (i) any actions to enforce rights to receive any payments or benefits which may be due Employee pursuant to Section 5 of the Employment Agreement, or under any of Employer’s employee benefit plans,
(ii) any rights or claims that may arise as a result of events occurring after the date this General Release of Claims is executed, (iii) any indemnification rights Employee may have as a former officer or director of Employer or its
subsidiaries or affiliated companies, (iv) any claims for benefits under any directors’ and officers’ liability policy maintained by Employer or its subsidiaries or affiliated companies in accordance with the terms of such policy, and
(v) any rights as a holder of equity securities of Employer. 
 2. Employee represents that he has not filed against the
Released Parties any complaints, charges, or lawsuits arising out of his employment, or any other matter arising on or prior to the date of this General Release of Claims, and covenants and agrees that he will never individually or with any person
file, or commence the filing of, any charges, lawsuits, complaints or proceedings with any governmental agency, or against the Released Parties with respect to any of the matters released by Employee pursuant to paragraph 1 hereof (a
“Proceeding”); provided, however, Employee shall not have relinquished his right to commence a Proceeding to challenge whether Employee knowingly and voluntarily waived his rights under ADEA. 
  

 23 








 3. Employee hereby acknowledges that Employer has informed him that he has up to twenty-one
(21) days to sign this General Release of Claims and he may knowingly and voluntarily waive that twenty-one (21) day period by signing this General Release of Claims earlier. Employee also understands that he shall have seven (7) days
following the date on which he signs this General Release of Claims within which to revoke it by providing a written notice of his revocation to Employer. 
 4. Employee acknowledges that this General Release of Claims will be governed by and construed and enforced in accordance with the internal laws of the State of Delaware applicable to contracts made and
to be performed entirely within such State. 
 5. Employee acknowledges that he has read this General Release of Claims, that he
has been advised that he should consult with an attorney before he executes this general release of claims, and that he understands all of its terms and executes it voluntarily and with full knowledge of its significance and the consequences
thereof. 
 6. This General Release of Claims shall take effect on the eighth day following Employee’s execution of this
General Release of Claims unless Employee’s written revocation is delivered to Employer within seven (7) days after such execution.
