Ladies and Gentlemen:

We have acted as special California counsel to AmSurg Corp. (the “Company”) and the State Guarantors (as defined below), such State Guarantors being organized and existing under the laws of the State of California, in connection with the filing by the Company with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-4 (the “Registration Statement”), which relates to the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and exchange of up to $1,100,000,000 aggregate principal amount of the Company’s 5.625% senior notes due 2022 (the “Exchange Notes”) that are to be unconditionally guaranteed on a senior unsecured basis by certain of the Company’s current and future direct and indirect subsidiaries, including the California entities set forth on Schedule I attached hereto (the subsidiary guarantors set forth on Schedule I attached hereto being referred to herein as the “State Guarantors”). The Exchange Notes are to be issued pursuant to an indenture, dated as of July 16, 2014, by and between AmSurg Escrow Corp. (“Escrow Corp”), and U.S. Bank National Associaton, as trustee (the “Trustee”), as supplemented further by the Supplemental Indenture, dated as of July 16, 2014, by and among the Company, the guarantors party thereto and the Trustee, as supplemented further by the Supplemental Indenture, dated as of October 8, 2014, by and among the Company, the guarantors party thereto and the Trustee, as supplemented further by the Supplemental Indenture, dated as of November 18, 2014, by and among the Company, the guarantors party thereto and the Trustee, and as supplemented further by the Supplemental Indenture, dated as of December 10, 2014, by and among the Company, the guarantors party thereto and the Trustee (collectively, the “Indenture”).

The Exchange Notes are to be issued in an exchange offer for a like aggregate original principal amount of currently outstanding 5.625% senior notes due 2022 in accordance with the terms of a Registration Rights Agreement, dated as of July 16, 2014, by and among Escrow Corp, the Company, the guarantors party thereto and Citigroup Global Markets Inc. as representative of the parties named therein as the initial purchasers (“Citigroup”), and the related Registration Rights Joinder, dated as of July 16, 2014, by and among Citigroup and the guarantors party thereto (collectively, the “Registration Rights Agreement”).
