DUBLIN, Ohio--(BUSINESS WIRE)-- Neoprobe Corporation (NYSE Amex: NEOP) today announced that Hercules Technology II, L.P, a fund managed by Hercules Technology Growth Capital, Inc. (Nasdaq: HTGC), will provide up to a total of $10 million in debt financing to Neoprobe. Hercules is a leading specialty finance company providing technology and life sciences companies with debt and equity growth capital.

"The successful arrangement of this financing bolsters our cash position with limited potential dilution as we close in on a number of important near-term milestones," stated Brent Larson, Senior Vice President and CFO of Neoprobe. "We are pleased to have the support and confidence of a leading technology and life sciences investor like Hercules as we continue to execute on our business plan objectives. This funding further strengthens our already solid balance sheet and provides us with the flexibility to consider additional product acquisition and partnership opportunities.”

"We appreciate the opportunity to contribute to Neoprobe’s growth. The company has achieved many significant milestones in building a pipeline of precision radiopharmaceutical diagnostic candidates," said Chad Norman, Managing Director at Hercules. "Currently, the Company has three drug candidates in late-stage development – Lymphoseek®, a receptor-based lymphatic tissue targeting agent, RIGScanTM, a tumor-specific targeting agent for the treatment of colorectal cancer and AZD4694, a Fluorine-18 labeled agent for use in the imaging and evaluation of patients with signs or symptoms of cognitive impairment such as Alzheimer’s disease. We are confident that Neoprobe’s strong management team will be able to seize on the considerable market opportunity for these promising product candidates.”
