The information set forth in Item 2.03 of this Current Report on Form 8-K is incorporated herein by reference.

Pursuant to a Registration Statement on Form S-4, File No. 333-171386 (the "Registration Statement"), USMD Holdings, Inc. ("Holdings") registered the issuance of up to 10,225,000 shares of its Common Stock to be issued in connection with a business combination described therein (the "Contribution") and in the Contribution and Purchase Agreement by and among Holdings, UANT Ventures, L.L.P. ("Ventures"), Urology Associates of North Texas, L.L.P. ("UANT") and USMD Inc. ("USMD"), dated as of August 19, 2010 (the "Original Contribution Agreement"). Pursuant to the terms of the Original Contribution Agreement, immediately prior to the Contribution, a subsidiary of Ventures would merge with and into UANT, resulting in UANT becoming a wholly-owned subsidiary of Ventures, and certain of the USMD shareholders would contribute all or a portion of their shares of USMD common stock to Ventures in exchange for partnership interests in Ventures. When the Contribution is consummated, Ventures would contribute its assets, which would include its equity interests in USMD and UANT, and the remaining USMD shareholders would contribute their USMD shares, to Holdings in exchange for shares of Holdings common stock.

In December 2011, Ventures entered into merger agreements with each of The Medical Clinic of North Texas, P.A. ("MCNT") and Impel Management Services, L.L.C. ("Impel"). These merger agreements (the "Merger Agreements") provided that subsidiaries of Ventures would merge with and into each of MCNT and Impel, resulting in these businesses becoming wholly-owned subsidiaries of Ventures prior to the closing of the Contribution. By virtue of the mergers, the equity interests in MCNT and Impel would convert into partnership interests in Ventures. Effective December 15, 2011, Holdings, USMD, UANT and Ventures entered into an Amendment to the Contribution and Purchase Agreement (the "Amendment" and collectively with the Original Contribution Agreement, the "Contribution Agreement") to reflect, among other changes, that, immediately following the mergers, Ventures would contribute to Holdings, in addition to its equity interests in USMD and UANT, its equity interests in MCNT and Impel as part of the Contribution. On May 21, 2012, Ventures, Holdings, MCNT and Impel executed a corresponding amendment to the merger agreements.

Effective August 31, 2012, Holdings and the other parties consummated the foregoing mergers and the Contribution.

The description of the transactions and agreements set forth above do not purport to be complete and are qualified in its entirety by reference to the Contribution Agreement and the Merger Agreements, which were filed by the Company as annexes to the Registration Statement.

A copy of the Company's press release dated September 7, 2012 announcing the closing of the Contribution is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Effective August 31, 2012 and in connection with the consummation of the Contribution, Holdings entered into agreements with JPMorgan Chase Bank, N.A. as Agent, and other lenders

Upon completion of the Contribution, Ventures was issued shares of Holdings Common Stock and immediately distributed approximately 534,000 shares of Holdings Common Stock to its partners on a pro rata basis. Pursuant to the terms of the Contribution Agreement, Ventures was also granted an option to purchase an additional 79,027 shares of Holdings Common Stock at an exercise price of $24.96 per share. As a result of this transaction structure, at the close of business on August 31, 2012, Ventures beneficially owned approximately 8,745,467 shares (approximately 86.5%) of the outstanding Common Stock of Holdings. Due to its ownership, Ventures is able by itself to elect all of the members of the board of directors of Holdings.

Employment Agreements

USMD Physician Services, a subsidiary of Holdings, has entered into employment
agreements with substantially all of the physicians who provide professional
medical services on behalf of UANT or MCNT. This includes the following
executive officers and/or directors who are engaged in medical practice:



        John House, M.D.         Chairman of the Board, CEO and President
