Hana Biosciences Receives $30 Million Funding Commitment

SOUTH SAN FRANCISCO, Calif. -- Hana Biosciences, a biopharmaceutical company focused on strengthening the foundation of cancer care, today announced that Deerfield Management, a leading healthcare investment fund, has committed up to $30 million in funding, including $7.5 million upfront, to assist with financing the development of the company’s pipeline of product candidates. Hana Biosciences is currently advancing two anti-cancer compounds through clinical trials, with additional therapeutic product candidates and an oncology supportive care product in late-stage preclinical development.

“This financing commitment provides us the resources to advance our pipeline of product candidates through the next stages of development and potential value formation,” said Steven R. Deitcher, M.D., President and Chief Executive Officer of Hana Biosciences. “We are aligned with respect to Hana’s pipeline potential, development strategy and future goals. We are focused on product development and dedicated to the steady growth of the company over the next several years.”

"In addition to Hana's clinical-stage programs, we believe that menadione represents an exciting opportunity in the treatment of one of the most common adverse events of modern biologic therapy," said Howard Furst, M.D., a Partner at Deerfield Management. "We believe that this type of financing vehicle will work well for the company in that it provides funds as needed, and recognizes concrete program milestones and development progress, while creating minimal dilution relative to the company's market capitalization and resource requirements."

Deerfield's commitment of up to $30 million is in the form of an interest-bearing loan that can be drawn down at pre-determined intervals over a three-year period. Hana will immediately draw down $7.5 million. The availability of one-third of the $30 million is subject to the achievement of specific milestones associated with the development of the company’s Marqibo and menadione product candidates. The outstanding principal and interest, which accrues at the rate of 9.85 percent per annum, is due by October 2013. Deerfield received a one-time 3.5 percent cash commitment fee and six-year warrants to purchase approximately 5.2 million shares of Hana’s common stock upon execution of the loan agreement at an exercise price of $1.31 per share, the closing bid price on October 30, 2007. Additional warrants will be issuable if the company draws down the portion of the loan facility subject to milestones. The warrants are subject to certain anti-dilution features.

“We are pleased that one of our top current shareholders has expressed its confidence in our company and assets with this financing. Hana has reached an important juncture in the maturation of our clinical-stage programs, and we believe this financing vehicle offers access to funds while addressing the best interests of our current shareholders,” added John Iparraguirre, Vice President, Chief Financial Officer of Hana Biosciences.
