Hercules Provides $5 Million in Debt Financing to CITTIO, a Provider of Innovative, Automated Network and Systems Monitoring Software

PALO ALTO, Calif.--(BUSINESS WIRE)--

Hercules Technology Growth Capital, Inc. (NASDAQ:HTGC), a leading specialty finance company providing growth capital to venture capital- and private equity-backed technology and life science companies, today announced that on April 10, 2007, it provided $5 million in debt financing to CITTIO, Inc., an automated network and systems monitoring software company.

CITTIO WatchTower(R), the company's flagship product, enables companies to increase IT productivity, efficiently manage distributed systems, reduce downtime and generate business value from the network. CITTIO WatchTower offers users the ability to monitor complex IT infrastructure from servers, routers and databases to point-of-sale systems and surveillance cameras by combining a platform-agnostic, web-based architecture with an automation stack for agent-free discovery, fingerprinting, monitoring, graphing, thresholding, alarms and notifications. Hummer Winblad Venture Partners and JK&B Capital are the leading investors in the company.

"As companies rely more heavily on large, complex networks, it becomes increasingly important to manage the performance and availability of their IT infrastructure," said Sam Bhaumik, senior managing director and head of the technology group at Hercules. "The existing and anticipated market demand, along with CITTIO's strong positioning, clearly distinguishes the company and made it a compelling financing decision for Hercules."

"CITTIO offers companies an alternative to the extensively complex and expensive network and systems monitoring software on the market today," said Jamie Lerner, president and chief executive officer of CITTIO. "With the growth capital from Hercules, we will expand our sales and marketing efforts for WatchTower as well as conduct additional research and development to accelerate future offerings."
