POZEN Reports Third Quarter 2003 Results; POZEN Reports Revenue for
the First Time in Company History

    CHAPEL HILL, N.C.--(BUSINESS WIRE)--Oct. 30, 2003--POZEN Inc.
(NASDAQ: POZN), today announced results for the third quarter ended
September 30, 2003.
    POZEN reported a net loss of $3.7 million, or $0.13 per share, for
the third quarter of 2003 compared with a net loss of $5.2 million, or
$0.19 per share, for the third quarter of 2002. The company reported a
net loss of $13.2 million, or $0.47 per share, for the nine months
ended September 30, 2003 compared with a net loss of $18.9 million, or
$0.67 per share, for the same period in 2002.
    POZEN reported revenue for the first time in the history of the
company. Revenue for the third quarter of 2003 totaled $1.9 million
resulting from the amortization of up-front payments received under
the licensing agreements for MT 100(TM), MT 300(TM), and MT 400(TM).
These agreements have terms that include up-front payments upon
contract signing and additional payments if and when certain product
development milestones are reached. The up-front payments are being
amortized over the period ending on the anticipated date of regulatory
approvals, as specified in the agreements relating to the product
candidates.
    Total operating expenses for the third quarter of 2003 were $5.7
million, as compared to $5.5 million for the same period in 2002. For
the nine-month period, total operating expenses decreased 21% to $15.5
million, due primarily to a reduced level of research and development
activities for MT 300 and MT 400.
    At September 30, 2003, cash and cash equivalents totaled $65
million compared with $50 million at December 31, 2002. The increase
in cash and cash equivalents resulted primarily from licensing fees
offset by expenses associated with operating activities.

    Business Highlights

    MT 100

    In October 2003, POZEN announced that the New Drug Application
(NDA) submitted to the U.S. Food and Drug Administration (FDA) in July
2003 for MT 100 was accepted for filing. The FDA has agreed to review
the NDA and accept POZEN's filing of the results of a rat
carcinogenicity study in early 2004. MT 100 is being developed as an
oral first-line therapy for the treatment of migraine.
    POZEN previously announced that it received a letter of comments
from an advisory group to the Medicines and Healthcare Products
Regulatory Agency (MHRA), relating to the Marketing Authorization
Application (MAA) for MT 100. POZEN intends to submit a response to
the comments raised by the advisory group. The Company will need to
satisfactorily address the issues raised, including providing
additional support for the benefits of the combination, in order to
obtain approval.
    Results from a recent Phase IIIb study showed that early treatment
with MT 100 improves efficacy. The rate of sustained pain relief for
migraine patients taking MT 100 in the study nears 50%. In addition,
data was presented at the XI Congress of the International Headache
Society showing that a two-tablet dose of MT 100 appears to be more
effective in providing pain relief at two hours than a single tablet
dose of Imitrex(R) 50mg in migraine patients with nausea or severe
pain at baseline. MT 100 was also shown to be well tolerated in a
long-term safety study.
    In July 2003, POZEN and Nycomed announced that they signed a
licensing agreement to commercialize MT 100 in four Nordic countries -
Denmark, Sweden, Norway, and Finland. The Nordic countries account for
approximately 18% of the European triptan market on a Euro basis.

    MT 300

    POZEN and Xcel Pharmaceuticals announced in September 2003 that
they signed a licensing agreement for the commercialization of MT 300,
an injectable product candidate for the treatment of migrane.
    In October, POZEN announced that it had received a not-approvable
letter from the FDA related to its NDA for MT 300. The letter was
issued based on the FDA's conclusion that while MT 300 achieved the
primary endpoint, it failed to achieve statistical significance versus
placebo for the relief at two hours of the ancillary symptoms of
migraine (nausea, sensitivity to light, and sensitivity to sound). No
clinical safety issues were identified in the letter, nor were any
non-clinical issues cited as impacting the FDA's decision to issue the
not-approvable letter. POZEN is committed to working with the FDA and
will seek to resolve the issues raised in the letter as soon as
possible.

    Other

    As part of its continuing efforts to expand into new therapeutic
areas, POZEN announced in July 2003 that it signed an exclusive option
agreement with Nycomed, under which POZEN may acquire a license to
certain rights related to lornoxicam, a non-steroidal
anti-inflammatory drug or NSAID. POZEN will explore the development of
novel product candidates containing lornoxicam alone or in combination
with other active ingredients for pain or other indications.

    Financial Guidance

    For the fourth quarter of 2003, POZEN expects total revenue to be
approximately $2.1 million. POZEN expects total operating expenses for
the fourth quarter of 2003 to be in the range of $4.0 million to $5.0
million.
    For the 2003 year, POZEN expects total revenue to be approximately
$4.0 million. POZEN expects total operating expenses for the 2003 year
to be in the range of $19.5 million to $20.5 million.

management's outlook at 11:00 a.m. Eastern time on Thursday, October
