Ladies and Gentlemen:

This letter agreement (this “Agreement”) amends and restates the letter agreement entered into between TPG Asia VI, L.P., a Cayman Islands limited partnership (the “Fund”), and Healthy Harmony Holdings, L.P., a Cayman Islands limited partnership (“Parent”), on February 17, 2014, and sets forth the commitments of the Fund, subject to the terms and conditions contained herein, to purchase, directly or indirectly, certain limited partnership interests of Parent. It is contemplated that, pursuant to that certain Amended and Restated Agreement and Plan of Merger (as further amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), dated as of the date hereof, by and among Chindex International, Inc., a Delaware corporation (the “Company”), Parent and Healthy Harmony Acquisition, Inc., a Delaware corporation and a wholly-owned Subsidiary of Parent (“Merger Sub”), Merger Sub will be merged with and into the Company (the “Merger”), with the Company being the surviving entity of such Merger and a wholly-owned subsidiary of Parent. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

1. Commitments. The Fund hereby commits (its “Commitment”), subject to the terms and conditions set forth herein, that, at or prior to the Closing, it shall purchase, or shall cause the purchase of, directly or indirectly through one or more intermediate entities, limited partnership interests of Parent with an aggregate purchase price of $455,000,000 solely to (i) fund all amounts required to be paid by the Parent pursuant to Sections 3.2(a) and 3.4(a) of the Merger Agreement, (ii) fund other payment obligations of Parent and Merger Sub required to be performed prior to and including the Effective Time under the Merger Agreement and (iii) pay all fees and expenses required to be paid by Parent pursuant to the Merger Agreement; provided, that the Fund shall not, under any circumstances, be obligated under this Agreement to contribute more than the Commitment to Parent. In the event Parent does not require the full amount of the aggregate of the Fund’s Commitment in order to consummate the Merger, the amount to be funded under this Agreement shall be automatically reduced to the level sufficient for Parent or Merger Sub to (a) pay the aggregate Merger Consideration, (b) make all required payments in respect of the Company Options and Restricted Stock, (c) perform Parent’s and Merger Sub’s other payment obligations required to be performed prior to and at the Effective Time and (d) pay all fees, expenses and other amounts related to the Transactions payable by either of them pursuant to the Merger Agreement.

2. Conditions. The Fund’s Commitment shall be subject to (i) the execution and delivery of the Merger Agreement by the Company, (ii) the satisfaction or waiver of each of the conditions to Parent’s and Merger Sub’s obligations to effect the Closing set forth in Sections 7.1 and 7.2 of the Merger Agreement (in each case, other than any conditions that by their nature are to be satisfied at the Closing, but subject to the prior or substantially concurrent satisfaction or waiver of such conditions), and (iii) the substantially simultaneous consummation of the Merger in accordance with the terms of the Merger Agreement. The Fund may allocate all or a portion of its investment to (i) one or more other investment vehicles managed or controlled by the Fund or any Affiliates of the Fund or such other vehicles, (ii) Significant Stockholder, (iii) after receipt of the Company Stockholder Approvals, other investors and (iv) subject to the prior written consent of the Company, other Persons, provided that in each case, (a) such allocation shall not relieve the Fund of its obligations hereunder if such Person to which such investment is allocated does not perform its obligations, and (b) the Fund’s Commitment hereunder will only be reduced by any amounts actually contributed to Parent by such Subsidiaries, investment vehicles or other Persons (and not returned) at or prior to the Closing Date for the purpose of funding a portion of the amounts described in clauses (i), (ii) and (iii) of Section 1 above; provided, further, that in the case of (ii) and (iii), such allocation shall not (x) impose additional Governmental Approvals required to consummate the Transactions or (y) be reasonably expected to materially delay the process for obtaining any Governmental Approvals required to consummate the Merger or the Fund’s performance under this Agreement. If the amount required to be paid pursuant to the Merger Agreement is less than the Fund’s Commitment, its Commitment hereunder will be reduced accordingly.

3. Limited Guarantee. Concurrently with the execution and delivery of this Agreement, the Fund is executing and delivering to the Company an amended and restated limited guarantee relating to Parent’s obligations under the Merger Agreement (the “Guarantee”). The Company’s rights pursuant to clause (ii) of the first sentence of Section 5 hereof, the Company’s rights against Parent and Merger Sub pursuant to the Merger Agreement, the Company’s right to assert any Retained Claim (as defined in the Guarantee) against the Non-Recourse Party(ies) (as defined in the Guarantee) against which such Retained Claim may be asserted pursuant to Section 9 of the Guarantee and the Company’s remedies against the Fund under the Guarantee shall be, and are intended to be, the sole and exclusive direct or indirect remedies available to the Company and its security holders and Affiliates against the Fund or any other Non-Recourse Party (against which a Retained Claim may be asserted pursuant to Section 9 of the Guarantee) in respect of any liabilities or obligations arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby or the negotiation thereof, including in the event Parent breaches its obligations under the Merger Agreement, whether or not such breach is caused by the Fund’s breach of its obligations under this Agreement.
