Effective September 7, 2012, D.R. Horton, Inc. entered into a five-year, $125 million senior unsecured revolving Credit Agreement (the “Revolving Credit Facility”) with The Royal Bank of Scotland plc, serving as Administrative Agent, and as the initial lender as of the effective date. The description and terms of the Revolving Credit Facility provided herein are qualified in their entirety by reference to the full and complete terms contained in the Revolving Credit Facility, which is attached to this Form 8-K as Exhibit 10.1. Capitalized terms not defined herein are defined in the Revolving Credit Facility.

As of September 7, 2012, the Revolving Credit Facility has an Aggregate Revolving Credit Commitment of $125 million, which may be increased or decreased from time to time pursuant to the terms thereof. The Revolving Credit Facility also has an uncommitted $375 million accordion feature which could increase the aggregate commitment amount under the Revolving Credit Facility to $500 million, subject to certain conditions and availability of additional bank commitments. The Revolving Credit Facility also provides for the issuance of letters of credit with a sublimit equal to 50% of the revolving credit commitment, for an initial sublimit of $62.5 million. The pricing for outstanding commitments, borrowings and letters of credit under the Revolving Credit Facility is determined by a Pricing Schedule that is based on the Company’s Leverage Ratio. The Revolving Credit Facility matures on September 7, 2017.

The Revolving Credit Facility contains two financial covenants that currently require the Company to maintain a minimum Tangible Net Worth and a Leverage Ratio below a maximum level as described in Article VII of the Revolving Credit Facility. Outstanding loans under the Revolving Credit Facility are guaranteed by the Company’s wholly-owned subsidiaries listed as guarantors to the Revolving Credit Facility.

All the information set forth above under Item 1.01 is hereby incorporated by reference into this Item 2.03.
