Item 2.03 — Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On September 18, 2013, we amended our Second Amended and Restated Credit Agreement dated as of November 29, 2010 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”) pursuant to an Eighth Amendment to Second Amended and Restated Credit Agreement and Limited Consent (the “Amendment”) by and among Clayton Williams Energy, Inc., a Delaware corporation, as Borrower, certain of our subsidiaries, as Guarantors, the Lenders party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent.

The Amendment raises the permitted ratio of our consolidated funded indebtedness to consolidated EBITDAX (as defined in the Credit Agreement and determined as of the end of each fiscal quarter for the then most-recently ended four fiscal quarters) to 4.5 to 1 from 4.0 to 1 during the period from the effective date of the Amendment to and including the fiscal quarter ending December 31, 2014.  The Amendment will be effective upon our closing of the private placement of senior notes due 2020 described under Item 7.01 of this Form 8-K.

This description of the Amendment is only a summary of, and is qualified in its entirety by reference to, the Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K.

Item 7.01 — Regulation FD Disclosure.

On September 23, 2013, we announced that we intend to offer, subject to market and other conditions, $250 million aggregate principal amount of senior notes due 2020 in a private placement to eligible purchasers.  We intend to use the net proceeds from the offering to repay borrowings under the Credit Agreement.  A copy of the press release announcing the offering is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The notes have not been registered under the Securities Act of 1933 (the “Securities Act”) or any state securities laws; and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

The information contained in this Current Report on Form 8-K is neither an offer to sell nor a solicitation of an offer to buy the notes or any other securities and shall not constitute an offer to sell or a solicitation of an offer to buy, or a sale of, the notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.
