EXPLANATORY NOTE

Pacira Pharmaceuticals, Inc. (the “Company”) is filing this Amendment No. 1 to its Current Report on Form 8-K filed on June 14, 2013 for the sole purpose of disclosing the Company’s decision regarding the frequency with which it will include an advisory vote to approve the compensation of its named executive officers in future annual meeting proxy materials.

Item 5.07.  Submissions of Matters to a Vote of Security Holders.

As previously reported, at the Company’s 2013 annual meeting of stockholders the option regarding the frequency (every year, every two years or every three years) of the advisory vote to approve the compensation of the Company’s named executive officers that received the highest number of votes cast was every “one year,” as recommended by the Company’s board of directors. In light of these results, the Company has determined to hold an advisory vote on named executive officer compensation every year until the next required advisory vote on the frequency of future votes on named executive officer compensation or until the Company’s board of directors otherwise determines that a different frequency for such advisory votes is in the best interests of the stockholders of the Company.
