Subsequent Events

On April 30, 2008, the Company closed a $30 million Senior Secured Credit Facility (the "Facility") with Greenleaf Investments LLC, a private company based in Victoria, Texas ("Greenleaf"). The Company acted as agent and sole lender for the Facility. Initial availability under the Facility is $12.5 million with approximately $10.5 million funded at closing. The Facility is secured by first liens on substantially all of Greenleaf's assets. As partial consideration for providing the Facility, the Company received an overriding royalty interest in Greenleaf's properties. Proceeds from the Facility will be used by Greenleaf to acquire certain properties in Victoria County, Texas, to develop additional oil and gas properties and to fund capital expenditures. Greenleaf is an oil and gas producer with interests in production located along the Texas Gulf Coast.

Also on April 30, 2008, the Company made a follow-on investment in an existing portfolio company, Tammany Oil & Gas, LLC. Availability under the facility was increased from $30.0 million to $34.0 million. The Company funded an additional $6.2 million, which was used to acquire certain producing properties in the federal waters of the Gulf of Mexico. Following the investment, there is approximately $29.5 million outstanding under the facility.

Following these transactions, the Company has committed and made available approximately $354.8 million to 16 portfolio companies, of which approximately $296.2 million is currently outstanding.
