Exhibit 99.1

             Hercules Technology Growth Capital Announces Its Ninth
                Consecutive Quarterly Dividend of $0.30 Per Share

  Dividend Represents $2.425 Per Share Distribution since Its IPO in June 2005

     PALO ALTO, Calif.--(BUSINESS WIRE)--Nov. 1, 2007--Hercules Technology
Growth Capital, Inc. (NASDAQ:HTGC), the premier specialty finance company
providing venture debt and equity to venture capital and private equity backed
technology and life science companies at all stages of development, today
announced that its Board of Directors has declared a third quarter dividend of
$0.30 per share. The dividend will be payable on December 17, 2007 to
shareholders of record as of November 16, 2007. The ex-dividend date is November
14, 2007. Specific tax characteristics of all dividends reported will be
reported to shareholders on Form 1099 after the 2007 year end.

     For the quarter ended September 30, 2007, the Company declared a
distribution of $0.30 per share. The determination of the tax attributes of the
Company's distributions is made annually as of the end of the Company's fiscal
year based upon its taxable income for the full year and distributions paid for
the full year; therefore, a determination made on a quarterly basis may not be
representative of the actual tax attributes of its distributions for a full
year. If the Company determined the tax attributes of its distributions
year-to-date as of September 30, 2007, 98% would be from ordinary income and 2%
would be a return of capital for stockholders; however, there can be no
certainty to shareholders that this determination is representative of what the
tax attributes of its 2007 distributions to shareholders will actually be. For
the fiscal year ended December 31, 2006, a portion of the distributions to the
Company's shareholders was deemed a return of capital.
