Somaxon Pharmaceuticals, Inc. Secures up to $65 Million in Financing

SAN DIEGO--(BUSINESS WIRE)--Somaxon Pharmaceuticals, Inc. (Nasdaq: SOMX - News), a specialty pharmaceutical company focused on the in-licensing and development of proprietary product candidates for the treatment of diseases and disorders in the fields of psychiatry and neurology, today announced that it has entered into a $15 million secured loan agreement with Oxford Finance Corporation and Silicon Valley Bank and a Committed Equity Financing Facility (CEFF) with Kingsbridge Capital Limited in which Kingsbridge has committed to provide up to $50 million of capital through the purchase of newly-issued shares of Somaxon’s common stock.

“These financing arrangements provide us with access to additional funds to support our preparation activities for the commercialization of SILENOR™, if it is approved by the FDA,” said David F. Hale, Somaxon’s Executive Chairman and Interim CEO. “In addition, the availability of these funds will support our financial position as we continue to move forward in discussions with a number of companies regarding a potential strategic collaboration relating to the commercialization of SILENOR™. We believe these transactions also provide us with the flexibility to access funding in ways that can allow us to minimize potential dilution for our stockholders.”

Secured Loan Agreement

Under the secured loan agreement, Somaxon borrowed $15.0 million from the lenders. The loan is secured by a first priority security interest in all of the company’s assets, other than its intellectual property and its rights under license agreements granting it rights to intellectual property. Somaxon also agreed not to pledge or otherwise encumber its intellectual property assets.

Somaxon will be required to pay interest on borrowings at the fixed, per-annum rate of 9.57% on a monthly basis through December 31, 2008. Thereafter, the company will be required to repay the principal plus interest in 30 equal monthly installments.

The loan documents contain typical upfront, final payment and prepayment fees. The company also has certain minimum cash balance requirements. In connection with entering into the loan agreement, Somaxon issued to the lenders warrants to purchase shares of the company’s common stock.

Committed Equity Financing Facility

Pursuant to the CEFF, Kingsbridge has committed to provide up to $50 million of capital for a period of three years through the purchase of newly-issued shares of Somaxon’s common stock. Under the terms of the CEFF, the maximum number of shares that Somaxon may sell (exclusive of the shares underlying a warrant issued concurrently to Kingsbridge with the CEFF) will be limited to the maximum number of shares the Company may sell under the rules of the Nasdaq Global Market without approval of its stockholders.

Subject to certain conditions, Somaxon may access capital under the CEFF in tranches of up to three percent (3%) of the company’s market capitalization at the time of the draw down of such tranche.

Kingsbridge will purchase shares of common stock pursuant to the CEFF at discounts ranging from six percent (6%) to twelve percent (12%), depending on the average market price of the common stock during the pricing period, provided that the volume weighted purchase price for any shares to be issued to Kingsbridge during the period exceeds a specified threshold.

In connection with the CEFF, Somaxon issued a warrant to Kingsbridge to purchase shares of Somaxon’s common stock.

The CEFF also requires Somaxon to file a registration statement with respect to the resale of shares issued pursuant to the CEFF and underlying the warrant within 60 days of entering into the CEFF, and to use commercially reasonable efforts to have such registration statement declared effective by the Securities and Exchange Commission within 180 days of entering into the CEFF.

Throughout the term of the agreement, Kingsbridge is restricted from engaging in any short selling transaction relating to Somaxon’s common stock. Somaxon is not obligated to utilize any of the $50 million available under the CEFF, and there are no minimum commitments or minimum use penalties. The CEFF agreement does not contain any restrictions on Somaxon’s operating activities, automatic pricing resets or minimum market volume restrictions.
