Hercules Technology Growth Capital Enhances and Amends Wells Fargo Credit Facility

Adds Amortization Period and Lowers Interest Rate Floor

PALO ALTO, Calif.--(BUSINESS WIRE)-- Hercules Technology Growth Capital, Inc. (NYSE: HTGC) (the “Company”) today announced that effective August 1, 2012, it enhanced and amended its credit facility with Wells Fargo Capital Finance (“WFCF”), part of Wells Fargo & Company (NYSE: WFC), under which WFCF has committed $75.0 million in initial credit capacity under a $300.0 million accordion credit facility. The amendment reduces the interest rate floor by 75 basis points to 4.25% and extends the maturity date by one year to August 2015. Additionally, an amortization period of 12 months was added to pay down the principal balance as of the maturity date.

"We are pleased to improve the terms on this facility and appreciate the continued support demonstrated by this leading financial institution," said Manuel A. Henriquez, co-founder, chairman and chief executive officer of Hercules. "The amended facility provides Hercules with an increased level of financial flexibility to execute our disciplined growth strategy.”

Borrowings under the amended facility are at an interest rate per annum equal to LIBOR plus 3.50%, consistent with prior facilities while the floor has been lowered to 4.25%, a 75 basis point reduction from the prior facility. The advance rate of 50% against eligible loans remains the same.

The facility also contains an accordion feature, in which the Company can increase the credit line up to an aggregate of $300.0 million, funded by additional lenders who may join the facility and with the agreement of WFCF and RBC Capital Markets and subject to other customary conditions. There can be no assurances that additional lenders will join the new credit facility.

For additional information, please review the company’s current report on Form 8-K, to be filed with the Security and Exchange Commission which will include the completed transaction documents.
