On October 30, 2013, in connection with the pricing of the initial public offering (the “Offering”) by Surgical Care Affiliates, Inc. (the “Company”) of its common stock, the Company converted from a Delaware limited liability company named ASC Acquisition LLC to a Delaware corporation named Surgical Care Affiliates, Inc. As part of the conversion, the Company filed its Certificate of Incorporation with the Secretary of State of the State of Delaware and adopted its By-Laws.

Additionally, in connection with the closing of the Offering on November 4, 2013, the Registration Rights Agreement, dated as of November 4, 2013 (the “Registration Rights Agreement”), was entered into by and among the Company, TPG Partners V, L.P., TPG FOF V-A, L.P. and TPG FOF V-B, L.P. (collectively, the “TPG Funds”), and certain members of the Company’s management and board of directors substantially in the form previously filed as Exhibit 4.1 to the Company’s Registration Statement on Form S-1 (File No. 333-190998), as amended (the “Registration Statement”). Also in connection with closing of the Offering, the Stockholders Agreement, dated as of November 4, 2013 (the “Stockholders Agreement”), was entered into by and among the Company and the TPG Funds substantially in the form previously filed as Exhibit 10.24 to the Company’s Registration Statement. Copies of the Registration Rights Agreement and Stockholders Agreement are filed as Exhibits 4.1 and 10.1, respectively, herewith and incorporated by reference herein.

On October 30, 2013, the Company entered into employment agreements with each of Andrew P. Hayek, Joseph T. Clark, Michael A. Rucker, Peter J. Clemens and Richard L. Sharff, Jr. (the “Executive Officers”), substantially in the form previously filed as Exhibits 10.15, 10.16, 10.17, 10.18 and 10.19, respectively (the “Employment Agreements”), to the Company’s Registration Statement.

The Employment Agreements establish a base salary for each of the Company’s Executive Officers, subject to possible annual increases as determined by the board of directors or its compensation committee. The annual base salaries in effect for Messrs. Hayek, Clark, Rucker, Clemens and Sharff are $595,327, $458,559, $424,337, $392,000 and $325,000, respectively. Mr. Hayek’s salary will be increased to $750,000 per year, and Mr. Sharff’s salary will be increased to $400,000, in each case effective January 1, 2014.

Additionally, the Employment Agreements provide that the Executive Officers are eligible to participate in a Senior Management Bonus Program, under which they may earn a cash bonus each year, subject to the achievement of Company and individual performance objectives established by the compensation committee. The target and maximum amounts of any annual bonus that may be earned by an Executive Officer are expressed as a percentage of the Executive Officer’s annual base salary in effect with respect to such year. The Employment Agreements also provide that each Executive Officer is entitled to participate in all savings and retirement plans and welfare benefits provided by the Company, which are generally made available to other executives.

The Employment Agreements contain standard ongoing confidentiality, non-solicitation and non-competition restrictions. The non-solicitation restrictions remain in place for 18 months for Messrs. Clark, Rucker, Clemens and Sharff and two years for Mr. Hayek, in each case following termination of employment, and the non-competition restrictions remain in place for 18 months for each of the Executive Officers following termination of employment.

Each of the Employment Agreements provide that if an Executive Officer is terminated for cause, or if he terminates his employment without good reason (as such terms are defined in the applicable Employment Agreement), he will be entitled to any earned and unpaid base salary and vacation. If an Executive Officer is terminated without cause or if he terminates his employment for good reason other than in connection with a change in control, he will be entitled to the following payments and benefits, in addition to payment of any earned but unpaid base salary and vacation and any earned but unpaid annual bonus for the prior fiscal year: (i) continued base salary payments for 18 months (24 months for Mr. Hayek) following the date of termination of employment, (ii) health insurance benefits for 18 months following the date of termination of employment or until he becomes re-employed with another employer and is eligible to receive health insurance benefits under another employer-provided plan, whichever comes earlier, and (iii) a pro rata portion of his annual bonus based upon the achievement of the applicable performance objectives.

2

In addition, each of the Employment Agreements provide that if an Executive Officer’s employment terminates as a result of his death or disability, he will be entitled to any earned and unpaid base salary and vacation through the date of his termination, any earned but unpaid annual bonus for the prior fiscal year, and a pro rata portion of his annual bonus based upon the achievement of the applicable performance objectives. In the event an Executive Officer’s employment is terminated without cause or for good reason within the three months prior to the consummation of, or within the twenty-four month period following, a change in control, in addition to any earned and unpaid base salary and vacation through the date of termination and any earned but unpaid bonus for the prior fiscal year, he will be entitled to (i) an amount equal to 1.5 times (two times in the case of Mr. Hayek) the sum of the Executive Officer’s then-current base salary and his target annual bonus, payable in a lump sum within forty days following the date of such termination, (ii) health insurance benefits for 18 months following the date of termination of employment or until he becomes re-employed with another employer and is eligible to receive health insurance benefits under another employer-provided plan, whichever comes earlier and (iii) a pro rata portion of his annual bonus based upon the achievement of the applicable performance objectives.

Payments of severance and other benefits following a termination by the Company without cause or by the Executive Officer for good reason are conditioned upon the Executive Officer executing a release of claims, and such release becoming effective, and compliance with restrictive covenants.

The foregoing summary of the Employment Agreements does not purport to be complete and is qualified in its entirety by reference to the terms of the Employment Agreements for Andrew P. Hayek, Joseph T. Clark, Michael A. Rucker, Peter J. Clemens and Richard L. Sharff, Jr., a copy of which are filed as Exhibits 10.2, 10.3, 10.4, 10.5 and 10.6, respectively, herewith and incorporated by reference herein.
