Item 8.01   Other Events.
Borrowing Base Affirmation. On September 17, 2009, Mariner Energy, Inc. (“Mariner”) was notified that the lenders under its secured revolving $1 billion credit facility affirmed the existing $800 million borrowing base, its amount since June 2009, and that the next borrowing base redetermination is scheduled for February 2010.
10b5-1 Plan. Effective September 15, 2009, an executive officer of Mariner adopted a prearranged plan with a brokerage firm to periodically sell some shares of Mariner’s common stock that he owns. The plan is intended to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and facilitates the officer’s personal long-term investment strategy for asset diversification and liquidity.
The officer, the total number of shares of Mariner common stock he owns (including shares issuable upon exercise of presently exercisable stock options), and the number of shares of Mariner common stock covered by his 10b5-1 plan are:
         
Name and Title   Total Shares Owned 09/15/09   Shares covered by 10b5-1 Plan
 
       
Richard Molohon,
  106,428   17,100
Vice President—Reservoir
       
Engineering
       
Under the plan, the brokerage firm may sell the covered shares subject to certain price limitations during specified times periods until September 15, 2010. The officer currently must report any sales under his plan on Form 4 filings with the Securities and Exchange Commission.
Rule 10b5-1 permits executives and other insiders to adopt a written stock sales plan at times when they do not possess material, non-public information, and to sell stock under the plan on a periodic basis and in a non-discretionary manner, regardless whether they possess material, non-public information at the time sales occur.
