Pacira Pharmaceuticals, Inc. (NASDAQ: PCRX) (the “Company”) today announced that it proposes to offer $100 million of aggregate principal amount of its convertible senior notes due 2019, subject to market conditions and other factors. The notes are to be offered and sold only to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The notes will be the senior, unsecured obligations of the Company and will accrue interest payable semiannually in arrears.

Pacira also expects to grant to the initial purchasers a 30-day option to purchase up to an additional $10 million of aggregate principal amount of the notes on the same terms and conditions, solely to cover sales in excess thereof, if any. Pacira intends to use approximately $30.0 million of the net proceeds of the offering to repay all amounts outstanding under, and to terminate, its senior secured credit facility, and the remainder of the net proceeds from the offering (including from any exercise by the initial purchasers of their option to purchase additional notes) to fund the continued commercialization of EXPAREL® and the development of additional indications for EXPAREL and for general corporate purposes.
