  La Jolla Pharmaceutical Company Calls Urgent Special Meeting of Stockholders
  on February 26, 2010 to Vote on Merger

Business Wire

SAN DIEGO -- February 16, 2010

La Jolla Pharmaceutical Company (NASDAQ: LJPC) today announced that it will
hold a special meeting of stockholders on February 26, 2010 at 3:00 p.m.
Pacific Time to vote on its proposed merger with Adamis Pharmaceuticals
Corporation (OTCBB: ADMP). Anyone who held La Jolla stock as of January 22,
2010 will receive proxy materials and be eligible to vote at the special
meeting.

It is imperative that La Jolla stockholders vote at this special meeting of
stockholders. Holders of more than 50% of La Jolla’s 65 million shares
outstanding are required to be present in person or represented by proxy to
hold the meeting. For the merger to be completed, holders of more than 50% of
La Jolla’s shares must vote in favor. If too few of La Jolla’s stockholders
vote, or if the merger is not approved, La Jolla will have limited cash
resources, and the La Jolla board of directors may elect to, among other
things, close the business and complete a voluntary dissolution under Delaware
law.

Dr. Deirdre Y. Gillespie, La Jolla’s CEO, stated, “This merger provides
potential upside for La Jolla’s stockholders as Adamis has current and
anticipated future revenues from its recently launched epinephrine syringe and
additional products in the pipeline. To close this deal, La Jolla’s unusually
large base of 12,000 stockholders need to act and vote - every vote is
critical. The likely alternative to the merger is to close the Company, in
which case we currently expect returning $0.02 - $0.03 per share to
stockholders.”

There is an extremely limited time to vote as all votes must be received
before Friday, February 26^th. La Jolla’s NASDAQ delisting hearing is
scheduled for February 25^th. Assuming the appeal is unsuccessful, La Jolla
expects that its common stock could be delisted as early as March 1.

shall there be any sale of securities in any jurisdiction in which such offer,
solicitation or sale would be unlawful prior to registration or qualification
