  NPS Pharmaceuticals Reports Fourth Quarter and Year-End Operating Results

    SALT LAKE CITY, Feb. 10 /PRNewswire-FirstCall/ -- NPS Pharmaceuticals,
Inc. (Nasdaq: NPSP) today reviewed progress with its late-stage product
candidates and reported its operating results for the three months and year
ended December 31, 2003.
    (Logo:  http://www.newscom.com/cgi-bin/prnh/20000218/NPSLOGO )

                                Product Review

    In 2003 NPS made significant clinical and regulatory progress in advancing
its pipeline of product candidates:

    PREOS(R)

     *  The company completed patient dosing with its proprietary compound
        PREOS in a pivotal, 18-month study known as TOP (Treatment of
        Osteoporosis with Parathyroid Hormone).  An open-label extension study
        with former TOP study patients is ongoing.

     *  NPS plans to make a report of top-line results from the TOP study by
        the end of the first quarter of 2004.  Data from other studies with
        PREOS are expected to be available later this year, or in 2005.
        The company plans to submit a New Drug Application (NDA) for PREOS to
        the U.S. Food and Drug Administration (FDA) at the end of the third
        quarter 2004.

     *  PREOS is also being tested in Europe in women using hormone
        replacement therapy in a study called POWER (Parathyroid Hormone for
        Osteoporotic Women on Estrogen Replacement).

     *  Researchers at the University of California San Francisco supervised
        the completion of a two-year clinical study of PREOS and alendronate
        (an anti-bone resorption drug) used in combination or in sequence.
        Final results are expected from the investigation sometime this year.

    Cinacalcet HCl

     *  In the third quarter of 2003, Amgen Inc., reported that an NDA had
        been filed for cinacalcet HCl, a small molecule licensed from NPS in
        1996.  Cinacalcet provides direct control of the secretion of
        parathyroid hormone, and may be useful as a treatment for
        hyperparathyroidism (HPT), a condition afflicting many people with
        chronic kidney disease or kidney failure.

     *  Amgen also announced that the FDA had granted a request for a priority
        review of the cinacalcet NDA.  NPS expects that Amgen will begin
        marketing cinacalcet in 2004, which will generate royalty revenue for
        the company.  If approved by the FDA, cinacalcet will be the first NPS
        drug to be made available commercially for patient use.

    Teduglutide

     *  In 2003, NPS announced the start of a proof-of-concept study with
        teduglutide in patients with Crohn's disease.  Teduglutide is a
        proprietary protein molecule that acts to stimulate cells that line
        the gastrointestinal tract to increase in number and size.
        Therapeutic benefit may be derived from the increased absorptive
        surface area and enhanced integrity of the intestinal wall that result
        from this effect.

     *  NPS plans to announce the start of a pivotal trial with teduglutide in
        patients with short bowel syndrome (SBS) in early 2004.

     *  The company has signed a Mutual Termination Agreement with Technology
        Partnership Canada (TPC), which relieves NPS of any potential
        obligations related to the development or commercialization
        of teduglutide.

    Isovaleramide

     *  The company is conducting a Phase IIa proof-of-concept study with
        isovaleramide in patients with migraine headaches.  Isovaleramide is a
        small molecule neuromodulator that is one of several NPS compounds
        active in preclinical models of central nervous system (CNS)
        disorders.

    mGluRs

     *  NPS is collaborating with AstraZeneca to find molecules that act on
        novel targets known as metabotropic glutamate receptors, or mGluRs.
        NPS and AstraZeneca are exploring possible applications of these
        compounds in the treatment of various central nervous system
        disorders, and in the treatment of gastroesophageal
        reflux disease, or GERD.

    Calcilytics

     *  NPS licensee GlaxoSmithKline (GSK) has begun clinical testing of small
        orally active molecules called calcilytics.  Calcilytics have the
        opposite action of calcimimetic compounds like cinacalcet, and can
        cause a transient increase in the release of parathyroid hormone,
        which may be beneficial in treating osteoporosis.  If calcilytic
        compounds are successful, GSK will make milestone and royalty payments
        to NPS, and NPS will have an option to co-promote calcilytic products
        with GSK in North America.

                              Financial Results

    NPS incurred a net loss for the fourth quarter of 2003 of $48.5 million,
or $1.31 per share, compared to a net loss in the fourth quarter of 2002 of
$25.4 million, or $0.76 per share.  For the year ended December 31, 2003, the
net loss was $170.4 million, or $4.71 per share, compared to $86.8 million, or
$2.79 per share for the year ended December 31, 2002.  The net loss for the
year ended December 31, 2003 includes expenses of $6.2 million relating to the
termination of the company's agreement with the Government of Canada pursuant
to the TPC program in the fourth quarter of 2003, and a $39.9 million expense
relating to a termination fee paid to Enzon Pharmaceuticals, Inc. in the form
of 1.5 million shares of the company's common stock and other costs associated
with the terminated merger in June 2003.

    Revenues for the fourth quarter of 2003 were $2.0 million, compared to
revenues of $133,000 for the same period last year.  Revenues for the year
ended December 31, 2003 were $9.9 million compared to $2.2 million in the same
period of 2002.  Substantially all revenues during the periods were from
development and license agreements.  The increases in revenues during 2003, as
compared to the same periods in the prior year, are primarily the result of a
$6.0 million milestone payment NPS received from Amgen, Inc. for the
submission of an NDA to the United States Food and Drug Administration for
cinacalcet HCl in September 2003 and a $2.0 million milestone payment received
from GSK for the initiation of a clinical study with a new calcilytic compound
in the fourth quarter of 2003.  Additionally, the company recognized
$1.5 million in revenue during 2003 as a result of our settled arbitration
with Forest Laboratories, Inc., which occurred in July 2003.

    Research and development expenses were $38.7 million for the fourth
quarter of 2003 compared to $22.7 million for the fourth quarter of 2002.  For
the year ended December 31, 2003, research and development expenses were
$118.2 million compared to $80.9 million for the same period in 2002.  The
increase in research and development expenses in the fourth quarter of 2003 as
compared to the fourth quarter of 2002 is principally due to a $3.5 million
increase in the costs associated with continued clinical development of PREOS,
a $5.1 million increase in the costs associated with advancing the teduglutide
clinical research program, a $1.3 million increase in the costs associated
with the manufacture of clinical and commercial supplies of PREOS and
teduglutide, and a $2.6 million increase in spending on the company's central
nervous system research programs.  The increase in research and development
expenses during the year ended December 31, 2003, as compared to the prior
year, is primarily due to a $16.2 million increase in the costs of advancing
the PREOS program, a $5.3 million increase in the costs of advancing the
teduglutide program, a $6.3 million increase in the costs associated with the
manufacture of PREOS, and a $6.6 million increase in the costs of advancing
our central nervous system programs.

    General and administrative expenses were $6.2 million for the quarter
ended December 31, 2003 compared to $4.4 million expended in the same quarter
in 2002.  For the year ended December 31, 2003, general and administrative
expenses were $20.3 million compared to $14.8 million for the same period in
2002.  The increases in general and administrative expenses during the three
months and year ended December 31, 2003, as compared with the same periods in
the prior year, are primarily due to increased marketing activities associated
with PREOS and teduglutide and additional administrative costs, including the
hiring of additional administrative personnel, with related benefits and
costs, and non-cash compensation expense related to modified stock options
upon the retirement of certain individuals.

    Amortization of intangibles of $394,000 and $1.5 million for the three
months and year ended December 31, 2003, respectively, are comparable to
$331,000 and $1.3 million for the same periods in the prior year.

    Merger costs and termination fees include $6.2 million relating to the
termination of the company's agreement with the Government of Canada related
to the TPC program in the fourth quarter of 2003, and $39.9 million relating
to the termination of the proposed merger agreement with Enzon in the second
quarter of 2003.  In December 2003 the company reached an agreement to
mutually terminate its contract with the Government of Canada under the TPC
program.  As a result, the company concluded that it was probable that it
would have to repay amounts previously paid by TPC under this agreement and
write off receivables due from TPC.  In exchange for mutual releases, the
company paid $4.3 million to the Government of Canada and released TPC from
all outstanding reimbursement obligations, resulting in the write-off of
$1.9 million in accounts receivable.  NPS was relieved of any further or
continuing obligations related to the development or commercialization of
teduglutide.  The company is continuing its clinical work with this compound.
Additionally, pursuant to the terms of the Enzon merger agreement, the company
issued Enzon 1.5 million shares of the company's common stock valued at
$35.6 million as a termination fee.  The company also incurred direct costs
relating to the proposed merger of approximately $4.3 million.

    Other income, net, decreased from $1.8 million to $173,000 for the three
months ended December 31, 2003 as compared with the same period in the prior
year.  Other income, net, decreased from $7.9 million to $3.3 million for the
year ended December 31, 2003 as compared with the same period in the prior
year.  The decreases in other income, net, in both periods, are primarily the
result of recording interest expense of $1.7 million and $3.7 million for the
three months and year ended December 31, 2003, respectively, on our
$192.0 million 3.0 percent convertible notes.  Additionally, interest income
decreased $919,000 during the year ended December 31, 2003, as compared to the
same period in the prior year, primarily due to lower interest rates during
2003 as compared to 2002.

    As of December 31, 2003, the company had 37.1 million shares outstanding
and $303.9 million in cash, cash equivalents, and marketable investment
securities as compared to $234.5 million at December 31, 2002.  The increase
in cash, cash equivalents and marketable investment securities was primarily
the result of the company's sale in July 2003 of $192.0 million of its
3% convertible notes due 2008.  The company received net proceeds of $185.9
million from the offering after deducting debt issuance costs.

     Cautionary Statement For The Purpose Of The "Safe Harbor" Provisions
           Of The Private Securities Litigation Reform Act of 1995

    Note:  Statements made in this press release, which are not historical in
nature, constitute forward-looking statements for purposes of the safe harbor
provided by the Private Securities Litigation Reform Act of 1995.  Such
statements include those regarding: our intent to make a report of top-line
data by the end of the first quarter 2004 and data from other studies later in
2004 and 2005; our intent to file an NDA for PREOS at the end of the first
quarter 2004; our expectation that Amgen will begin marketing cinacalcet HCl
in 2004; our intention to announce the start of a pivotal trial with
teduglutide in early 2004; and, our intent to commercialize small molecules
and recombinant proteins as drugs, specifically, our product candidates, PREOS
and cinacalcet HCl.  These statements are based on management's current
expectations and beliefs and are subject to a number of factors and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements.  Such risks and uncertainties
include:  we may not be able to collect, assemble and analyze data from the
PREOS trials in a timely manner; the data from the TOP study may not justify
filing an NDA for PREOS; we have never filed an NDA and may not be able to do
so in a timely manner; we do not have and may never develop any products that
generate revenues; our product candidates may not prove to be safe or
efficacious; the FDA may delay approval or may not approve any of our product
candidates; current collaborators or partners may not devote adequate
resources to the development and commercialization of our licensed drug
candidates which would prevent or delay introduction of drug candidates to the
market; we may be unable to generate adequate sales and marketing capabilities
to effectively market and sell our products; failure to secure adequate
manufacturing and storage sources for our products could result in disruption
or cessation of our clinical trials and eventual commercialization of such
products; and, we may not have or be able to secure sufficient capital to fund
development and commercialization of our product candidates.  All information
in this press release is as of February 10, 2004, and we undertake no duty to
update this information.  A more complete description of these risks can be
found in our filings with the Securities and Exchange Commission, including
our Annual Report on Form 10K for the year ended December 31, 2003.
