  La Jolla Pharmaceutical Company Announces the Adjournment of Special Meeting
  of Stockholders

Business Wire

SAN DIEGO -- March 01, 2010

La Jolla Pharmaceutical Company (NASDAQ: LJPC) today announced that its
Special Meeting of Stockholders, which was initially convened on February 26,
2010, was adjourned to March 2, 2010 at 3:00 p.m., local time, at 4365
Executive Drive, Suite 300, San Diego, California. As described in the joint
proxy statement/prospectus distributed to stockholders on or about February
12, 2010, the stockholders of La Jolla are being asked to vote on proposals
related to its proposed merger with Adamis Pharmaceuticals Corporation (OTCBB:
ADMP).

Holders of only twelve percent (12%) of La Jolla’s outstanding common stock
returned their proxy cards or otherwise indicated their votes with respect to
these proposals prior to the start of the stockholders’ meeting. The votes
cast as of the meeting date overwhelmingly supported the merger proposals,
including the reverse stock split. Separately, Adamis announced today that its
stockholders approved the proposed merger transaction.

There is no guarantee that we will be able to further adjourn and reconvene
the meeting to solicit additional votes. If La Jolla is delisted from Nasdaq
before the special stockholders’ meeting, La Jolla expects that it would need
Adamis’ consent and additional regulatory approvals to continue soliciting
proxies resulting in significant additional costs and time delays. Such
consents and approvals are difficult to obtain and may not be obtained at all.

Holders of more than 50% of La Jolla’s 65 million shares outstanding must vote
in order to hold the meeting. For the merger to be completed, holders of more
than 50% of La Jolla’s shares must vote in favor. Only stockholders who held
La Jolla stock on January 22, 2010 are eligible to vote.
