Item 8.01 Other Events.

The Registrant has extended the expiration date of its exchange offer (the "Offer") to acquire at least a majority of the issued and outstanding limited partner interests ("LP Interests") in Main Street Capital II, LP ("MSC II"), a privately-owned Delaware limited partnership, in exchange for shares of common stock of the Registrant ("Shares"), to 5:00 p.m. Central Standard Time on December 30, 2009, unless further extended. As of November 23, 2009, owners representing approximately 84% of the total dollar-value of LP Interests had elected to exchange pursuant to the Offer. Although the Registrant has satisfied the condition that it receive an election to exchange from greater than a majority of the LP Interests, consummation of the transactions contemplated in the Offer remains subject to final approval of the United States Small Business Administration ("SBA"). Consequently, the Offer is required to be extended until SBA final approval is received and any other outstanding conditions to close are satisfied.

The information disclosed under Item 8.01 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934 and shall not be deemed incorporated by reference into any filing made under the Securities Act of 1933, except as expressly set forth by specific reference in such filing.
