Core-Mark Announces Rule 10b5-1 Stock Trading Plans for CEO

SOUTH SAN FRANCISCO, CA--(Marketwire - September 3, 2009) - Core-Mark Holding Company, Inc. (NASDAQ: CORE), one of the leading wholesale distributors to the convenience retail industry in North America, announced that J. Michael Walsh, the Company's Chief Executive Officer, has adopted two Rule 10b5-1 trading plans.

Mr. Walsh has 100,000 options which expire in August of 2011. These options have a strike price of $15.50 per share. The first 10b5-1 plan calls for the sale of a portion of the shares to cover the exercise costs and income taxes associated with these options. Barring some unforeseen circumstance, it is Mr. Walsh's intention to hold the remaining shares until his retirement.

In addition, Mr. Walsh has three tranches of restricted stock units (RSU) from the 2004, 2005 and 2007 LTIPs totaling approximately 27,000 shares, the receipt of which will become taxable to Mr. Walsh upon expiration of the deferral period in 2010. Similarly, the second Rule 10b5-1 plan will enable the sale of sufficient shares to cover the tax consequence of these awards. Again it is Mr. Walsh's intention to hold the net shares from these RSUs until his retirement.

Rule 10b5-1 allows insiders to adopt written plans for trading securities in a non-discretionary, pre-scheduled manner in order to avoid concerns about initiating stock transactions when the insider may be aware of non-public information. Such plans also allow insiders to diversify their holdings and to sell shares to cover tax obligations. Once the transactions described above are concluded, Mr. Walsh's holdings of Core-Mark common stock will increase.
