Main Street Capital Declares Initial
 Quarterly Dividend of $0.33 Per Share

HOUSTON, TEXAS, November 5, 2007– Main Street Capital Corporation (NASDAQ-GS: MAIN) (“Main Street”) announced today that its Board of Directors declared an initial quarterly dividend of $0.33 per share.  The initial dividend represents an 8.8% annual yield based upon the $15.00 per share initial public offering price.

This initial dividend is being paid based upon the accumulated taxable income recognized by Main Street, including the gain realized from the previously announced sale of portfolio company All Hose & Specialty, LLC.   For tax purposes, it is estimated that approximately 67% of this initial dividend will be designated as long-term capital gain with the remainder reflected as ordinary taxable income.  The final determination of the tax attributes for this dividend will be made after the close of the 2007 tax year and may differ from the estimates above.  In addition, it is currently estimated that Main Street will generate taxable income for its 2007 tax year in excess of the initial quarterly dividend.  Main Street intends to carry over any undistributed excess 2007 taxable income, net of a 4% excise tax, for distribution to its shareholders in 2008.

The initial quarterly dividend will be payable on November 30, 2007 to shareholders of record on November 16, 2007.
