Item 1.01                                           Entry into a Material Definitive Agreement.

Fifth Amended and Restated Credit Agreement

On April 12, 2013, SM Energy Company (the “Company”) entered into a Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) by and among the Company, Wells Fargo Bank, National Association, as Administrative Agent (the “Agent”), and the institutions named therein as lenders.  The $2.5 billion Senior Secured Revolving Credit Facility provided for by the Credit Agreement (the “Revolving Credit Facility”) is secured by substantially all of the proved oil and natural gas properties of the Company.  The Credit Agreement replaces the Company’s Fourth Amended and Restated Credit Agreement with the Agent and certain other lenders named therein.

The Revolving Credit Facility has a maximum credit amount of $2.5 billion, with total initial lender commitments of $1.3 billion.  The Revolving Credit Facility is scheduled to mature on April 12, 2018.  Borrowings under the Revolving Credit Facility will accrue interest, at the Company’s election, (i) at the Alternate Base Rate, plus a margin ranging from 0.50% to 1.50% or (ii) for LIBOR borrowings, at the Adjusted LIBO Rate, plus a margin ranging from 1.50% to 2.50%.  “Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of (i) the Prime Rate in effect on such day, (ii) the Federal Funds Effective Rate in effect on such day plus ½ of 1% and (iii) the Adjusted LIBO Rate for a one month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1.0%.  “Adjusted LIBO Rate” means the reserve-adjusted LIBO Rate for a given Interest Period, rounded upwards, if necessary, to the next 1/16 of 1%.  The undrawn portion of the total commitments will be subject to a commitment fee ranging from 0.375% to 0.50%.

The applicable margin and commitment fee is dependent upon borrowings relative to the then-effective borrowing base.  The initial borrowing base is $1.9 billion, which has been increased from the Company’s prior borrowing base of $1.55 billion.  The borrowing base will be redetermined by the lenders at least semi-annually on each April 1 and October 1, beginning October 1, 2013.  The Company and the lenders may each request one unscheduled borrowing base redetermination between each scheduled redetermination.  The borrowing base will also be reduced in certain circumstances upon any issuance of senior unsecured or subordinated debt, upon cancellation of certain hedging positions and as a result of certain asset sales.

The Revolving Credit Facility contains customary covenants including, but not limited to, (i) a minimum current ratio and a maximum leverage ratio and (ii) limitations on incurrence of indebtedness, liens on assets, dividends and redemptions, investments, transactions with affiliates, mergers and consolidations and sales of assets.  The Revolving Credit Facility also includes customary lending conditions, representations and warranties, events of default and indemnification provisions.

Affiliates of certain of the lenders under the Revolving Credit Facility have provided from time to time, and may provide in the future, investment and commercial banking and financial advisory services to the Company and its affiliates in the ordinary course of business, for which they have received, and may continue to receive, customary fees and commissions.
