About AcelRx Pharmaceuticals, Inc.

AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on
the development and commercialization of innovative therapies for the
treatment of acute and breakthrough pain. AcelRx's lead product candidate,
Zalviso™, is designed to solve the problems associated with post-operative
intravenous patient-controlled analgesia which has been shown to cause harm to
patients following surgery because of the side effects of morphine, the
invasive IV route of delivery and the complexity of infusion pumps. AcelRx
has announced positive results from each of the three Phase 3 clinical trials
for Zalviso and AcelRx anticipates submitting a New Drug Application (NDA)
with the FDA in the third quarter of 2013. AcelRx also announced positive
top-line results for a Phase 2 trial for ARX-04, a sufentanil formulation for
the treatment of moderate-to-severe acute pain, funded through a grant from
the U.S. Army Medical Research and Materiel Command. The company has two
additional pain treatment product candidates, ARX-02 and ARX-03, which have
completed Phase 2 clinical development. For additional information about
