GSC Investment Corp. Amends Credit Facility with Deutsche Bank AG

Agreement Provides Additional Borrowing Capacity and Risk Protection

NEW YORK, March 24 /PRNewswire-FirstCall/ -- GSC Investment Corp. (NYSE: GNV),
a business development company, today announced that it has amended its credit
facility with Deutsche Bank AG. The amendment increases the portion of the
portfolio that can be invested in "CCC" rated investments in return for an
increase in financing costs and expedited loan amortization.

"We are pleased to have reached this agreement with our lender," said Seth M.
Katzenstein, Chief Executive Officer of GSC Investment Corp. "Despite the
increase in borrowing costs, the increase in the limit for "CCC" rated
investments improves the Company's ability to navigate the current credit
environment. We view this as a positive development for our shareholders."

As amended, the credit facility requires the Company to amortize the facility
over the next two years using principal proceeds from realizations and
repayments, and a portion of the interest proceeds generated from the
Company's investments. Any amounts remaining outstanding after the
amortization period will be due in full on the second anniversary of the
amendment. The margin on the facility has been increased from 70 basis points
over the commercial paper rate to 400 basis points during the first year, and
to 500 basis points during the following year. $58 million is currently
outstanding under the facility.
