ITEM 1.01                                  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

As described more fully under Item 2.03 below, which description is incorporated herein by reference, on May 1, 2014, Cimarex Energy Co. and its subsidiary guarantors (collectively, the “Company”) entered into a Second Amendment (the “Second Amendment”) to a Credit Agreement dated as of July 14, 2011, as previously amended by the First Amendment to Credit Agreement dated as of July 19, 2012 (collectively, the “Credit Agreement”), by and among the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the Lenders party thereto.  A copy of the Second Amendment is attached hereto as Exhibit 10.2 and is incorporated herein by reference.

ITEM 2.03                                  CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT

On May 1, 2014, the Company entered into the Second Amendment to the Credit Agreement.  The Credit Agreement initially provided for a senior unsecured revolving credit facility with an initial aggregate commitment from the lenders of $800 million (with an $80 million sub-limit for letters of credit), an initial borrowing base of $2.0 billion and an expiration of July 14, 2016.

The Second Amendment:

·                  increases the borrowing base from $2.0 billion to $2.5 billion until the next redetermination scheduled for April 2015

·                  extends the maturity date to July 14, 2018

·                  reduces the applicable margins for borrowings under the Credit Agreement so that, at Cimarex’s option, borrowings under the Credit Agreement may bear interest at either:

a London Interbank Offered (“LIBO”) rate plus 1.5 to 2.25 percent, based on the leverage ratio, or

the higher of (i) a prime rate, (ii) the federal funds effective rate plus 0.50 percent, or (iii) a LIBO rate plus 1.00 percent plus, in each case, an additional 0.5 to 1.25 percent, based on the leverage ratio.

·                  reduces the commitment fee for unused borrowings to .3-0.50 percent, based on the leverage ratio.

The current aggregate commitment from lenders is $1.0 billion.

The Second Amendment is filed as an exhibit to this Current Report on Form 8-K and is incorporated herein by reference, and the Company is filing for informational purposes the First Amendment to Credit Agreement as an additional exhibit to this Current Report on Form 8-K.
