AGREEMENT

JOINDER AGREEMENT AND AMENDMENT NO. 1 to CREDIT AGREEMENT (this “Joinder”), dated as of October 30, 2014 (“Increased Amount Date” or “Amendment No. 1 Effective Date”), to the Credit Agreement, dated as of September 30, 2011, as amended and restated as of March 7, 2014, among HCA Inc., a Delaware corporation (the “Parent Borrower”), the Subsidiary Borrowers party thereto, the lenders party thereto, Bank of America, N.A., as Administrative Agent, Swingline Lender and Letter of Credit Issuer, and the other agents and bookrunners party thereto (the “Credit Agreement”). Capitalized terms used herein and not defined herein shall have the meanings assigned to such terms in the Credit Agreement.

1. The Lenders listed on Exhibit A hereto (each, an “Incremental Revolving Loan Lender” and together, the “Incremental Revolving Loan Lenders”) have been approached by the Parent Borrower, and have committed to provide an Incremental Revolving Credit Commitment of $750,000,000 in the aggregate. After giving effect to such Incremental Revolving Credit Commitments, the aggregate Revolving Credit Commitments shall be increased on the Increased Amount Date from $2,500,000,000 to $3,250,000,000 (the “Revolving Commitment Increase”).

2. The Parent Borrower hereby represents and warrants as of the Increased Amount Date to the Administrative Agent, each Lender and the Incremental Revolving Loan Lenders that all of the conditions set forth in Section 2.14 of the Credit Agreement with respect to the Revolving Commitment Increase have been satisfied and the Parent Borrower is in compliance with all of the terms of such Section. The Increased Amount Date shall be the date that all of the conditions in Section 6 of this Joinder shall have been satisfied, which date shall be October 30, 2014.

3. Pursuant to Section 2.14 of the Credit Agreement, by execution and delivery of this Joinder, each Incremental Revolving Loan Lender’s Revolving Credit Commitment shall be the amount set forth on Exhibit A hereto and each Incremental Revolving Loan Lender shall for all purposes of the Credit Documents be deemed a “Lender” under the Credit Agreement.

4. For the avoidance of doubt, the Revolving Credit Commitments of the Incremental Revolving Loan Lenders shall be on identical terms as the Revolving Credit Commitments as in effect immediately prior to giving effect to the effectiveness of the Revolving Commitment Increase.

5. Amendments to Credit Agreement

(b) The definition of “Revolving Credit Commitment” in Section 1.1 of the Credit Agreement shall be amended by replacing “as of the Restatement Effective Date is $2,500,000,000” with “as of the Amendment No. 1 Effective Date is $3,250,000,000, as may be increased from time to time on any Increased Amount Date to the extent of such Incremental Revolving Credit Commitment.”

(c) Schedule 1 to the Credit Agreement shall be amended and restated as provided in Exhibit A to this Joinder.

6. Conditions. The obligation of the Incremental Revolving Loan Lenders to provide the Incremental Revolving Credit Commitments and the effectiveness of the Revolving Commitment Increase referred to above are subject to the following conditions precedent:

(c) The Administrative Agent shall have received the executed legal opinion of Simpson Thacher & Bartlett LLP, special New York counsel to the Parent Borrower in form and substance satisfactory to the Administrative Agent. The Parent Borrower, the other Credit Parties and the Administrative Agent hereby instruct such counsel to deliver such legal opinion.

(d) For each Credit Party, the Administrative Agent shall have received a short-form (where applicable) good standing certificate in such Credit Party’s state of formation, each dated a recent date prior to the Increased Amount Date and certified by the applicable secretary of state.

(e) The reimbursement or payment of all reasonable out-of-pocket expenses (including the reasonable fees and expenses of Cahill Gordon & Reindel llp, special counsel to the Administrative Agent) required to be reimbursed or paid by the Parent Borrower hereunder or under the Credit Agreement, in each case to the extent invoiced.

7.

8. The Credit Parties hereby confirm that the Security Documents and the obligations of such parties under the Credit Documents continue in full force and effect and shall not be affected by this Joinder (it being understood that the “Obligations” are increased as provided herein). Each of Holdings and Parent Borrower hereby further ratifies and reaffirms the validity and enforceability of all of the Liens and security interests heretofore granted, pursuant to and in connection with the Security Documents, to the Administrative Agent, as collateral security for the Obligations under the Credit Documents in accordance with their respective terms, and acknowledges that all of such Liens and security interests, and all Collateral heretofore pledged as security for such Obligations, continue to be and remain Collateral for such obligations from and after the date hereof.

9. This Joinder shall be deemed a Credit Document under the Credit Agreement.

10. Severability. Any provision of this Joinder held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

11. GOVERNING LAW. THIS JOINDER AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

12. Submission to Jurisdiction; Waivers. Each party hereto irrevocably and unconditionally:

-3-

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Person at its address set forth on Schedule 14.2 to the Credit Agreement or at such other address of which the Administrative Agent shall have been notified pursuant to Section 14.2 of the Credit Agreement;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and
