Other than in the performance of his duties hereunder, during the Non-Solicit Restrictive Period, Executive shall not, directly or indirectly, as employee, agent, consultant, stockholder, director, co-partner or in any other individual or representative capacity, employ, recruit or solicit for employment or engagement, any person who is employed or engaged by the Parent, the Company or any of their Subsidiaries or any of its Affiliated Practices during the Non Solicit Restrictive Period, or otherwise seek to influence or alter any such person’s relationship with any of the Affiliated Practices, the Parent, the Company or any of their Subsidiaries; provided, however that responses to a general solicitation (such as an internet or newspaper solicitation) that are not targeted towards any particular person shall not be deemed to be a violation of the restrictions set forth in this Section 7(c).

(d)Affiliated Practice. For purposes of this Agreement, an “Affiliated Practice” shall include any practice or facility (i) in which the Parent, Company or any of their Subsidiaries has an ownership interest or (ii) that is managed by or receives other services from the Parent, the Company or any of their Subsidiaries in connection with any element of the Business.

(e)Blue Pencil. If any court of competent jurisdiction shall at any time deem the term of this Agreement or any particular Restrictive Covenant (as defined below) too lengthy or the Territory too extensive, the other provisions of this Section 7 shall nevertheless stand, the Restrictive Period herein shall be deemed to be the longest period permissible by law under the circumstances and the Territory herein shall be deemed to comprise the largest territory permissible by law under the circumstances. The court in each case shall reduce the time period and/or Territory to permissible duration or size.

(f)Covenant Not to Disparage. During the Restrictive Period and thereafter, Executive shall not disparage, denigrate or derogate in any way, directly or indirectly, the Parent, the Company, any of their Subsidiaries or Affiliates, or any of its or their respective agents, officers, directors, employees, parent, subsidiaries, affiliates, Affiliated Practices, affiliated doctors (including any physicians who utilize or have invested in any Affiliated Practice), representatives, attorneys, executors, administrators, successors and assigns (collectively, the “Protected Parties”), nor shall Executive disparage, denigrate or derogate in any way, directly or indirectly, his experience with any Protected Party, or any actions or decisions made by any Protected Party.

(g)Remedies. Executive acknowledges and agrees that the covenants set forth in this Section 7 and the preceding Sections 5 and 6 (collectively, the “Restrictive Covenants”) are reasonable and necessary for the protection of the business interests of the Company, Parent and their Subsidiaries and Affiliates, that irreparable injury may result to the Company, Parent and their Subsidiaries and Affiliates if Executive breaches any of the terms of said Restrictive

Covenants, and that in the event of Executive’s actual or threatened breach of any such Restrictive Covenants, the Company, Parent and their Subsidiaries and Affiliates will have no adequate remedy at law. Executive accordingly agrees that in the event of any actual or threatened breach by his of any of the Restrictive Covenants, the Company, Parent and their Subsidiaries and Affiliates shall be entitled to immediate temporary injunctive and other equitable relief subject to hearing as soon thereafter as possible. Nothing contained herein shall be construed as prohibiting the Company, Parent or any of their Subsidiaries or Affiliates from pursuing any other remedies available to it for such breach or threatened breach, including the recovery of any damages which it is able to prove. In addition and supplementary to other rights and remedies existing in its (or their) favor, in the event of the material breach by Executive of any of the provisions of this Section 7, the Company or Parent (and/or their Subsidiaries or Affiliates) shall be entitled to require the Executive to account for and pay over to the Company or Parent (and/or their Subsidiaries or Affiliates) all compensation, profits, moneys, accruals, increments or other benefits actually derived from or received as a result of any transactions constituting a breach of the covenants contained in this Agreement which may require Executive to repay any severance. In addition, in the event of an alleged breach or violation by Executive of this Section 7, the restricted periods set forth in this Section 7 shall be tolled until such breach or violation has been duly cured.

(h)The Executive understands that the foregoing restrictions may limit his ability to earn a livelihood in a business similar to the business of the Company, Parent and their Subsidiaries or Affiliates, but he nevertheless believes that he has received and will receive sufficient consideration and other benefits as an executive of the Company and as otherwise provided hereunder to clearly justify such restrictions which, in any event (given his education, skills and ability), the Executive does not believe would prevent his from otherwise earning a living. Executive acknowledges that the Restrictive Covenants are reasonable and that he has reviewed the provisions of this Agreement with his legal counsel. The Executive shall inform any prospective or future employer of any and all restrictions contained in this Agreement and provide such employer with a copy of such restrictions, prior to the commencement of that employment.

8.Executive’s Representations and Covenants.

(a)Executive hereby represents and warrants to the Company that (i) the execution, delivery and performance of this Agreement by Executive do not and shall not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which he is bound, (ii) Executive is not a party to or bound by any employment agreement, non-compete agreement or confidentiality agreement with any other person or entity which will survive the Closing and (iii) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid and binding obligation of Executive, enforceable in accordance with its terms; provided that the covenants, agreements and obligations contained herein shall be contingent upon, and subject to, the occurrence of the Closing. Executive hereby acknowledges and represents that he has consulted with independent legal counsel regarding his rights and obligations under this Agreement and that he fully understands the terms and conditions contained herein.

(b)During the Employment Period and thereafter, Executive shall cooperate with the Company, Parent and their Subsidiaries and Affiliates in any internal investigation or administrative, regulatory or judicial proceeding as reasonably requested by the Company (including, without limitation, Executive being available to the Company upon reasonable notice for interviews and factual investigations, appearing at the Company’s request to give testimony without requiring service of a subpoena or other legal process, volunteering to the Company all pertinent information and turning over to the Company all relevant documents which are or may come into Executive’s possession, all at times and on schedules that are reasonably consistent with Executive’s other permitted activities and commitments). In the event the Company requires Executive’s cooperation in accordance with this Section 8(b), the Company shall reimburse Executive for reasonable travel expenses (including, without limitation, travel expenses, lodging and meals, and reasonable attorneys’ fees upon submission of receipts).

9.Survival. Sections 4 through 22 shall survive and continue in full force in accordance with their terms notwithstanding the expiration or termination of the Employment Period.

11.Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

12.Complete Agreement. This Agreement, those documents expressly referred to herein and other documents of even date herewith, embody the complete agreement and understanding among Executive and the Company and its Subsidiaries and, as of the Effective Date, shall supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way. Upon the Commencement Date, Executive will no longer be a participant in Symbion Inc. Executive Change in Control Severance Plan (the “Plan”) and Executive hereby releases the Company and its Subsidiaries and waives any claims or rights that he may have under the Plan or any other prior or existing agreement or understanding he may have with the Parent, the Company or any of their Subsidiaries, Affiliates or predecessors, including, but not limited to, any claim for severance or other benefits. To the extent that any inconsistency exists between this Agreement and the LLC Agreement, the language of this Agreement shall supersede.

13.No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction will be applied against any party hereto.

14.Counterparts. This Agreement may be executed in separate counterparts (including by facsimile or PDF signature pages), each of which is deemed to be an original and all of which taken together constitute one and the same agreement.

15.Successors and Assigns. This Agreement is intended to bind and inure to the benefit of and be enforceable by Executive and the Company or Parent and their respective successors and permitted assigns. Executive may not assign any of his rights or obligations hereunder without the prior written consent of the Company. The Company may (a) assign any or all of its respective rights and interests hereunder to Parent or one or more Subsidiaries or Affiliates of Parent or the Company, (b) designate one or more Subsidiaries or Affiliates of Parent or Company to perform its obligations hereunder (in any or all of which cases the Company nonetheless shall remain responsible for the performance of all of its obligations hereunder), (c) assign its rights hereunder in connection with the sale of all or a substantial part of the business or assets of the Company or Parent or one of their Subsidiaries (whether by merger, sale of stock or assets, recapitalization or otherwise) and (d) merge any of the Subsidiaries or Affiliates with or into the Company (or vice versa); provided, however, that the foregoing actions may provide Executive with Good Reason to terminate this Agreement. The rights of the Company hereunder are enforceable by Parent or the Company Subsidiaries or Affiliates, which are the intended third party beneficiaries hereof and no other third party beneficiary is so otherwise intended.

16.Delivery by Facsimile or PDF. This Agreement and any amendments hereto, to the extent signed and delivered by means of a facsimile machine or PDF, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto, each other party hereto shall re-execute original forms thereof and deliver them to the other party. No party hereto shall raise the use of a facsimile machine or PDF to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or PDF as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

17.Income Tax Treatment. Executive and the Company acknowledge that it is the intention of the Company to deduct all cash amounts paid under this Agreement as ordinary and necessary business expenses for income tax purposes. Executive agrees and represents that he will treat all such non-reimbursable amounts as ordinary income for income tax purposes, and should he report such amounts as other than ordinary income for income tax purposes, he will indemnify and hold the Company harmless from and against any and all taxes, penalties, interest, costs and expenses, including reasonable attorneys’ and accounting fees and costs, which are incurred by Company directly or indirectly as a result thereof.

18.Governing Law. This Agreement shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of

this Agreement shall be governed by, the laws of the state in which Executive resides, without giving effect to provisions thereof regarding conflict of laws.

19.Waiver of Jury Trial. THE PARTIES HERETO HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT. THE PARTIES HERETO ALSO WAIVE ANY BOND OR SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE REQUIRED OF THE OTHER PARTY. THE PARTIES HERETO ACKNOWLEDGE THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS ALREADY RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED FUTURE DEALINGS. THE COMPANY AND EXECUTIVE FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH THEIR RESPECTIVE LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES THEIR RESPECTIVE JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THE TRANSACTION CONTEMPLATED HEREBY. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

20.Consent to Jurisdiction.

(a)THE COMPANY AND EXECUTIVE HEREBY CONSENT TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE STATE IN WHICH EXECUTIVE RESIDES AND IRREVOCABLY AGREE THAT SUBJECT TO THE COMPANY’S ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT SHALL BE LITIGATED IN SUCH COURTS. EXECUTIVE ACCEPTS FOR HERSELF AND IN CONNECTION WITH HIS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT.

(b)Notwithstanding Section 20(a), the parties intend to and hereby confer jurisdiction to enforce the covenants contained in Sections 5 through 7 upon the courts of any jurisdiction within the geographical scope of such covenants. If the courts of any one or more of such jurisdictions hold such covenants wholly or partially invalid or unenforceable by reason of the breadth of such scope or otherwise, it is the intention of the parties that such determination not bar or in any way affect the Company’s right to the relief provided above in the courts of any other jurisdiction within the geographical scope of such covenants, as to breaches of such

covenants in such other respective jurisdictions, such covenants as they relate to each jurisdiction being, for this purpose, severable into diverse and independent covenants.

21.Amendment and Waiver. Any provision of this Agreement may be amended or waived only with the prior written consent of the Company and Executive, and no course of conduct or course of dealing or failure or delay by any party hereto in enforcing or exercising any of the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement or be deemed to be an implied waiver of any provision of this Agreement.

22.Section 409A. To the maximum extent permitted by law, this Agreement shall be interpreted in such a manner that the payments to Executive under this Agreement are either exempt from, or comply with, Section 409A of the Internal Revenue Code and the regulations and other interpretive guidance issued thereunder (collectively, “Section 409A”), including without limitation any such regulations or other guidance that may be issued after the Commencement Date. For purposes of Section 409A, the right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” as defined in Section 409A as of Executive’s termination of employment, then, to the extent any payment under this Agreement resulting from Executive’s termination of employment constitutes deferred compensation (after taking into account any applicable exemptions from Section 409A) and to the extent required by Section 409A, no payments due under this Agreement as a result of Executive’s termination of employment may be made until the earlier of (a) the first day following the sixth month anniversary of Executive’s date of termination and (b) Executive’s date of death; provided, however, that any payments delayed during this six-month period shall be paid in the aggregate in a lump sum as soon as reasonably practicable following the sixth month anniversary of Executive’s date of termination.

IN WITNESS WHEREOF, the parties hereto have executed this Employment Agreement as of the date first written above.
