Dear Tom:

This letter is to confirm your designation by the board of directors (the “Board”) of Surgical Care Affiliates, Inc., a Delaware corporation (“SCA”), as the Chair of SCA’s Compliance Committee and the Chair of SCA’s Acquisition Committee, and your agreement to serve a Chair of each of these committees. The terms of this letter agreement (this “Agreement”) will be effective as of January 1, 2014 (the “Effective Date”) and will augment and supplement the existing director compensation arrangement described in that certain letter agreement dated December 7, 2012.

Effective January 1, 2014, you will receive an annual aggregate cash retainer of $15,000, representing two individual retainers of $7,500 each for serving as Chair of the Compliance Committee and the Chair of the Acquisition Committee, payable in equal quarterly installments of $3,750 in arrears within 30 days after the end of each quarter of service (if you serve part of a quarter, the payment will be prorated based on the number of weeks in the quarter served and paid within 30 days of the termination of your service).

You will be expected to use your reasonable best efforts to attend all Compliance Committee and Acquisition Committee meetings, either in person or by telephonic or other electronic means. Reasonable expenses actually incurred by you in traveling to the Compliance Committee or Acquisition Committee meetings shall be reimbursed by SCA upon presentation of such documentation as SCA may reasonably request.

Your continued service on the Board will be subject in all respects to the Certificate of Incorporation and Bylaws of SCA and the General Corporation Law of Delaware.
