ITEM 1   BUSINESS.
 
GENERAL
 
    NPS Pharmaceuticals is engaged in the discovery and development of
orally-active, small molecule drugs that target selected biological targets,
including cell surface receptors and ion channels. The Company's most advanced
development program involves the development of a small molecule drug for the
treatment of hyperparathyroidism ("HPT"). The HPT program arose from the
Company's pioneering work on a new class of cell surface receptors which detect
levels of extracellular calcium involved in numerous bodily functions. The
Company is also applying its calcium receptor technology to the development of
therapies for osteoporosis. The Company's other main programs involve the
development of orally-active, small molecule drugs which have neuroprotectant
properties and target certain calcium channels in order to provide treatments
for stroke and head trauma. Additionally, the Company is pursuing several
discovery programs which are extensions of its discoveries in calcium receptors
and ion channels.
 
    NPS has established in the field of HPT a research collaboration and license
arrangement with the Pharmaceutical Division of Kirin Brewery Company, Limited
("Kirin") and a development and license arrangement with Amgen Inc. ("Amgen").
With regards to the field of osteoporosis, the Company has established a
research collaboration and license arrangement with SmithKline Beecham
Corporation ("SmithKline Beecham"). Kirin, SmithKline Beecham and Amgen are
referred to herein as the "Licensees." The Licensees are responsible for all
costs of product development in their respective territories and fields. As part
of these arrangements, the Licensees have paid to NPS an aggregate of $21.0
million in non-refundable license fees and Amgen and an affiliate of SmithKline
Beecham have also purchased $14.5 million of the Company's Common Stock. In
addition, the Licensees have made or have agreed to make up to an aggregate of
$56.0 million in milestone payments, of which $2.0 million has been paid to the
Company through December 31, 1996 under the Kirin agreement and $3.0 million has
been paid to the Company through December 31, 1996 under the SmithKline Beecham
agreement. SmithKline Beecham and Kirin are also obligated to pay research and
development support payments to the Company. Approximately $7.9 million has been
paid to the Company through December 31, 1996. Each of the Licensees is
obligated to pay royalties to NPS on any product sales. See "Risk
Factors--Dependence on Collaborative Research and License Relationships" and
"Business--Collaborative Research and License Agreements."
 
    HPT is a growing medical concern and is typically characterized as being
either primary or secondary. Primary HPT is an age-related disorder that results
from excessive secretion of parathyroid hormone ("PTH"), leading to elevated
levels of calcium in the blood. Symptoms may include bone loss, muscle weakness,
depression and cognitive dysfunction. There are currently no pharmaceutical
therapies for the treatment of primary HPT, with surgery being the only
effective treatment. Secondary HPT results from other disease states and is most
often associated with renal dysfunction. Symptoms of secondary HPT include
excessive bone loss, bone pain, and chronic, severe itching. The Company
believes that current
 
                                       1
<PAGE>
drug therapy treatments for secondary HPT, such as phosphate binders and
calcitriol have certain disadvantages.
 
    Prior to entering into the arrangements with Kirin and Amgen, the Company
had initiated and conducted four clinical trials of the Company's lead drug
candidate NPS R-568 in the United States. Under the Amgen agreement, Amgen
acquired full authority and assumed full responsibility for the further
development and commercialization of a drug for HPT. Amgen has informed the
Company that it has commenced a Phase II clinical trial in the United States on
NPS R-568 and is continuing to develop its clinical strategy for the development
of a drug to treat HPT. Effective June 30, 1995, Kirin acquired full authority
and assumed full responsibility for the development of a drug for HPT in Japan,
China (including Hong Kong), North and South Korea and Taiwan. Kirin commenced a
Phase I clinical trial of NPS R-568 in Japan in October 1996. NPS is working
with Amgen and Kirin to discover, identify and characterize back-up and second
generation compounds for the treatment of HPT. There can be no assurance that
the clinical trials will proceed as indicated or that NPS R-568 will prove safe
and effective, meet applicable regulatory standards or be successfully marketed
or that suitable back-ups or later generation compounds will be identified or
that if identified any such back-up or later generation compound will prove safe
and effective, meet applicable regulatory standards, or be successfully
marketed. See "Risk Factors--Early Stage of Product Development;" and
- --"Dependence on Collaborative Research and License Relationships."
 
    In conjunction with SmithKline Beecham, NPS is also applying its calcium
receptor technology to the development of orally-active therapeutics for the
treatment of osteoporosis. Osteoporosis is an age-related disorder affecting
more than 200 million people worldwide and is characterized by reduced bone
density and an increased susceptibility to fractures. Among the elderly in
particular, osteoporosis is a major cause of morbidity and mortality. The
Company is pursuing two approaches for the treatment of osteoporosis,
stimulation of bone formation and suppression of bone resorption. Most
osteoporosis patients are first diagnosed only after they have already lost
significant bone mass. As a result, the Company believes that a therapy that not
only halts further bone loss, but that also builds new bone, would constitute a
significant advancement in the treatment of osteoporosis. Under its
collaboration with SmithKline Beecham, research efforts are being conducted by
NPS concurrently on both approaches to osteoporosis. In January 1996, the
Company received a milestone payment of $3.0 million from SmithKline Beecham for
progress made in its osteoporosis program. In October 1996, the term of research
support obligation of SmithKline Beecham was extended for an additional year.
 
    The Company is developing a new class of orally-active compounds which
modulate certain calcium channels for neuroprotection in stroke and head trauma.
The influx of calcium through glutamate receptor-operated calcium channels has
been linked to a number of neurological disorders, including nerve cell death
following stroke and head trauma. The Company's proprietary compounds antagonize
the NMDA (N-methyl-D-aspartate) subtype of glutamate receptor-operated calcium
channels ("NMDA receptor-operated calcium channels"), thereby reducing the
influx of calcium. The Company believes that these compounds work through a
novel mechanism and exhibit potentially advantageous pharmacological properties.
These compounds demonstrated neuroprotectant activity in preclinical animal
models of stroke and head trauma. The Company has designated one of these
compounds, NPS 1506, for preclinical development and expects to file an
Investigational New Drug Application ("IND") and begin clinical trials in the
United States by June 30, 1997.
 
    The Company is actively engaged in several discovery programs which seek to
identify molecular targets for the development of new drugs. Among these, the
Company believes it has made significant discoveries with regard to novel forms
of metabotropic glutamate receptors ("mGluRs"), and has identified small
molecules active at these receptors. The Company believes that drugs acting at
specific mGluRs may provide relevant therapies for a number of neurological
disorders.

PRODUCT DEVELOPMENT PROGRAMS
 
    The Company's primary product development programs are centered around its
calcium receptor technology. Clinical development of orally-active compounds
that target calcium receptors as drug therapies for HPT is being advanced by
Kirin, NPS's collaborator and licensee for Japan, China (including Hong Kong),
Taiwan, North Korea, and South Korea and by Amgen for the rest-of-the world.
Together with SmithKline Beecham, the Company is pursuing orally-active
compounds targeting calcium receptors as drug therapies for osteoporosis. The
Company is also pursuing orally-active compounds that target NMDA
receptor-operated calcium channels as neuroprotectants to reduce neurological
damage associated with stroke or head trauma.
 
    Calcium levels in the blood are tightly regulated. The Company's calcium
receptor technology represents a novel method of regulating circulating calcium
levels. Calcium receptors are the basis of a newly discovered mechanism by which
certain cells detect and respond to small changes in the level of extracellular
calcium. One key role of calcium receptors is to regulate secretion of PTH and
calcitonin, two hormones which play opposing roles in bone and mineral
metabolism. The Company believes that manipulation of PTH and calcitonin levels
could be beneficial in the treatment of various disorders, such as HPT and
osteoporosis. The Company has utilized its expertise in certain functional
screening technologies and its proprietary recombinant cell lines to discover
and develop orally-active compounds which can directly manipulate the
circulating levels of PTH and calcitonin by modulating the activities of calcium
receptors. Compounds which mimic or potentiate the effect of extracellular
calcium at calcium receptors are referred to as "calcimimetics" (agonists) while
those which block the effect of calcium at such receptors are referred to as
"calcilytics" (antagonists).
 
    NMDA receptor-operated calcium channels play critical roles in normal
excitatory neurotransmission and are also recognized for their major role in
events which lead to much of the neurological damage associated with stroke and
with head trauma. Several pharmaceutical companies have recognized the potential
of NMDA receptor-operated calcium channels as molecular targets for the
development of drugs to treat neurological disorders and have identified various
lead compounds. Such work is all the more challenging because NMDA
receptor-operated calcium channels are also the site of action of phencyclidine
("PCP"; angel dust), and most compounds which target NMDA receptor-operated
calcium channels exhibit undesirable PCP-like side effects such as inducing
symptoms of psychosis. The Company has utilized its expertise in certain
functional screening technologies to discover and develop orally-active
compounds which antagonize NMDA receptor-channels by binding to a novel site,
distinct from the PCP binding site. The Company's compounds have not exhibited
PCP-like effects in a variety of IN VITRO and IN VIVO studies in animals
intended to identify PCP-like effects.

HYPERPARATHYROIDISM PROGRAM
 
    OVERVIEW.  HPT is a growing medical concern. It is typically characterized
as being either primary or secondary. Primary HPT is an age-related disorder
that results from excessive secretion of PTH. PTH acts in the kidney and on bone
to elevate the levels of calcium in the blood. Symptoms may include bone loss,
muscle weakness, depression and cognitive dysfunction. Approximately 100,000 new
patients are diagnosed with primary HPT in the United States each year. There
are currently no pharmaceutical therapies for the treatment of primary HPT.
Surgical removal of the affected parathyroid gland(s) from the neck region is
presently the only effective treatment.
 
    Secondary HPT results from other disease states and is most often associated
with renal dysfunction. Symptoms of secondary HPT include excessive bone loss,
bone pain, and chronic, severe itching. Studies have also shown that secondary
HPT develops early in the course of renal failure, before patients start
dialysis. Current treatments for secondary HPT involve drug therapy with
phosphate binders and/or
 
                                       4
<PAGE>
calcitriol. The Company believes that these therapies have certain
disadvantages. For example, phosphate binders are not well tolerated by many
people and calcitriol often leads to hypercalcemia and hyperphosphatemia which
can exacerbate the underlying disease. In severe cases, surgery may be required
to remove all or some of the parathyroid glands.
 
    The results of the Company's research and preclinical and clinical trials
have led the Company to believe that calcimimetic compounds (calcium receptor
agonists) could prove to be effective in treating both types of HPT. NPS is no
longer conducting clinical trials in this field. Amgen and Kirin are now
conducting further clinical trials to confirm this conclusion. PTH secretion is
normally regulated by changes in the circulating level of calcium. Increased
levels of circulating calcium activate the parathyroid cell calcium receptor,
which then suppresses the secretion of PTH. In HPT, however, PTH levels remain
elevated. NPS R-568 is a calcimimetic compound which activates the calcium
receptor on parathyroid cells, thereby reducing the secretion of PTH. The
Company has entered into agreements with Amgen and Kirin relating to the
development and commercialization of calcimimetic compounds for HPT. See
"Business-- Collaborative Research and License Agreements."

    IN HPT, EXCESS PTH TRIGGERS CHANGES IN BONE AND IN THE KIDNEY, THEREBY
    INCREASING THE LEVEL OF CALCIUM IN THE BLOOD.
 
    CALCIMIMETIC DRUGS, SUCH AS NPS R-568, ACTIVATE CALCIUM RECEPTORS
    LEADING TO SUPPRESSION OF PTH SECRETION. IN PATIENTS WITH HPT,
    CALCIMIMETIC DRUGS ARE EXPECTED TO AMELIORATE SYMPTOMS CAUSED BY EXCESS
    PTH AND HIGH CALCIUM LEVELS.

    DEVELOPMENT STATUS.  Prior to entering into the respective agreements with
Amgen and Kirin, the Company had commenced clinical trials of NPS R-568 in the
United States. These included two Phase I safety and tolerance studies, a
multi-site, Phase I/II study in women with mild, primary HPT and a pilot Phase
I/II study in kidney dialysis patients with secondary HPT. Kirin has initiated
(beginning in October 1996) clinical trials for NPS R-568 in Japan. Amgen
informed the Company that it began a Phase II trial for NPS R-568 in dialysis
patients in 1996. NPS is actively working with Amgen and Kirin, to discover,
identify and characterize back-up and second generation compounds. Each compound
which might be considered by Amgen and Kirin is subject to the same contractual
provisions governing development and is subject to the same royalty and
milestone obligations as NPS R-568. There can be no assurance that clinical
trials will proceed as indicated or that NPS R-568 or any other compound will
prove safe and effective, meet applicable regulatory standards or be
successfully marketed. See "Risk Factors--Early Stage of Product Development"
and --"Dependence on Collaborative Research and License Relationships."
 
OSTEOPOROSIS PROGRAM
 
    OVERVIEW.  Osteoporosis is an age-related disorder which affects more than
200 million people worldwide and is characterized by reduced bone density and an
increased susceptibility to fractures. Osteoporosis is a major cause of
morbidity and mortality among the elderly.
 
    Throughout life, bone undergoes constant remodeling involving anabolic
processes leading to bone formation and catabolic processes leading to bone
resorption. The balance between these two processes determines whether there is
net bone loss, net bone formation or no net change. In osteoporosis, this
balance has shifted in favor of bone resorption, resulting in net bone loss.
 
    Current drugs approved for the treatment of osteoporosis include estrogen,
injectable calcitonin, and alendronate (a bisphosphonate). These drugs are
anti-resorptives and act to suppress bone resorption. The Company believes that
each of these therapies presents one or more disadvantages. For example, use of
estrogen is believed to be associated with increased risk of breast cancer,
calcitonin is expensive and cannot currently be administered orally and
bisphosphonates have been associated with side effects such as gastrointestinal
distress. In contrast, anabolic agents stimulate new bone formation. While no
anabolic agents are currently available for the treatment of osteoporosis, the
FDA's Endocrinologic and Metabolic Drugs Advisory Committee has recently
recommended that slow- release fluoride, an anabolic agent, be approved for the
treatment of osteoporosis in postmenopausal patients who have suffered a
fracture.
 
    Most osteoporosis patients are first diagnosed after they have already lost
significant bone mass. As a result, the Company believes that a therapy that not
only halts further bone resorption but also builds new bone would constitute a
significant advancement in the treatment of osteoporosis. Under its
collaboration with SmithKline Beecham, research efforts are being conducted by
NPS concurrently on both stimulation of bone formation and suppression of bone
resorption. Both of these approaches are focused on the development of
orally-active molecules that are particularly suitable for long-term therapy.
 
    BONE FORMATION.  NPS's primary approach to the treatment of osteoporosis is
currently focused on calcilytic compounds (calcium receptor antagonists) which,
in contrast to calcimimetic compounds, stimulate secretion of PTH. The Company
believes that this novel approach, which is intended to manipulate the body's
own PTH reserves, could provide an effective anabolic therapy for osteoporosis,
stimulating new bone formation to replace bone which has already been lost to
the disease.
 
    While chronically high levels of PTH are known to cause bone loss as in HPT,
PTH levels fluctuate daily and this is thought to play a key role in regulating
the normal balance between bone resorption and bone formation. Recent studies in
animals and in humans have shown that frequent (usually daily) injections of
exogenous PTH sufficient to cause a transient increase in circulating PTH levels
result in significant stimulation of new bone formation. Several published
animal studies have evaluated the structural integrity of the newly formed bone
and have found that the increases in bone mass achieved with
 
                                       6
<PAGE>
PTH injections are accompanied by improvements in biomechanical strength and in
certain indices of bone structure thought to be related to biomechanical
strength.
 
    Although the anabolic effects of PTH on bone were first noted over 60 years
ago, evaluation of the therapeutic potential of PTH treatment has only recently
begun. Because of its potential as an effective anabolic therapy for
osteoporosis, certain other companies are currently conducting clinical trials
of injectable PTH or PTH analogs for osteoporosis. However, PTH is currently
expensive to manufacture and cannot be administered orally. The Company believes
that orally-administered, calcilytic drugs acting on the parathyroid cell
calcium receptor to increase PTH release from the body's own PTH reserves could
provide a cost-effective means of intermittently increasing PTH levels and could
lead to greater patient compliance and therefore greater acceptance.
 
                                   [PICTURE]
 
THE COMPANY IS WORKING IN COLLABORATION WITH SMITHKLINE BEECHAM TO DEVELOP
CALCILYTIC DRUGS THAT, BY BLOCKING THE PARATHYROID CELL CALCIUM RECEPTOR, WOULD
STIMULATE LOW-LEVEL, INTERMITTENT SECRETION OF PARATHYROID HORMONE, THEREBY
STIMULATING NEW BONE FORMATION.
 
    The Company has demonstrated in IN VIVO animal studies that intermittent
increases in circulating levels of PTH can be obtained by regulating the
activity of calcium receptors on the parathyroid cells. Increased levels of PTH
achieved by this mechanism are equivalent to levels of PTH achieved by an
injection of PTH sufficient to cause bone growth.
 
    SUPPRESSION OF BONE RESORPTION.  Bone resorption is the function of
specialized bone cells called osteoclasts. NPS is pursuing new anti-resorptive
therapies which involve calcimimetic drugs acting indirectly on osteoclasts via
C-cells of the thyroid. The Company believes that orally-active calcimimetic
drugs could provide cost-effective alternatives to current anti-resorptive drugs
and could potentially lead to greater patient compliance.
 
    C-cells of the thyroid secrete the hormone, calcitonin. Osteoclasts are
known to possess cell membrane receptors for calcitonin. Activation of these
receptors by calcitonin suppresses osteoclastic bone resorption. Studies in
animals and in humans have shown that repetitive injections of calcitonin
(usually daily) are effective at inhibiting bone resorption, and injectable
calcitonin is currently used in some countries as a therapy for osteoporosis.
The Company's novel approach is to develop orally-active drugs
 
                                       7
<PAGE>
which can be used to manipulate the body's own internal reserves of calcitonin
in order to achieve a similar effect.
 
    NPS and its collaborators at The Brigham and Women's Hospital, Inc.
("Brigham and Women's") have confirmed that calcium receptors are present on
C-cells of the thyroid and that activation of C-cell calcium receptors induces
calcitonin secretion. In animal studies, the Company has demonstrated that oral
administration of calcimimetic compounds stimulates secretion of calcitonin and
can lead to increased circulating calcitonin levels. Further IN VIVO studies are
necessary to determine if this approach will result in a significant decrease in
bone resorption.

CALCIMIMETIC DRUGS THAT ACTIVATE C-CELL CALCIUM RECEPTORS INCREASE CALCITONIN
LEVELS IN THE BLOOD. CALCITONIN ACTS DIRECTLY ON OSTEOCLAST CALCITONIN RECEPTORS
TO SUPPRESS BONE RESORPTION ACTIVITY. CALCIMIMETIC DRUGS ACTING ON A DISTINCT
OSTEOCLAST CALCIUM RECEPTOR THAT NPS IS WORKING TO IDENTIFY WOULD MIMIC THE
EFFECT OF EXTRACELLULAR CALCIUM, DIRECTLY SUPPRESSING BONE RESORPTION ACTIVITY.
 
    PRECLINICAL RESEARCH STATUS.  In January 1996, the Company received the
first milestone payment of $3.0 million from SmithKline Beecham for progress
made in its osteoporosis program. Medicinal chemistry efforts are being applied
at NPS and SmithKline Beecham to various lead compounds with the goal of
identifying clinical development candidates. NPS has produced a cell line that
expresses the human parathyroid and C-cell calcium receptor and serves as a
proprietary tool for the high-throughput screening of compounds to identify new
drug candidates. The Company continues to screen SmithKline Beecham and NPS
compound libraries and to discover, identify and characterize additional
compounds with calcilytic or calcimimetic activity. There can be no assurance
that lead compounds will be identified as proprietary clinical development
candidates, that preclinical and clinical trials will proceed as indicated or
that such candidates will prove safe and effective, meet applicable regulatory
standards or be successfully marketed. See "Risk Factors--Early Stage of Product
Development."

NEUROPROTECTION PROGRAM--NPS 1506
 
    OVERVIEW.  Stroke is the third leading cause of death in the United States,
with over 500,000 cases reported each year. In stroke, a blood vessel becomes
blocked, leading to inadequate blood supply (ischemia) to the brain. While many
stroke victims survive, approximately 100,000 to 150,000 per year are left
severely and permanently disabled by nerve damage resulting from stroke. Much of
this damage occurs within the first 24 to 48 hours after the incident and is
caused in part by the excessive release of glutamate and the resultant influx of
calcium into nerve cells. Published research in animals has shown that much of
this damage can be prevented by blocking the influx of calcium into cells,
especially the influx which results from the activation of NMDA
receptor-channels. Calcium influx resulting from the activation of NMDA
receptor-channels also appears to cause neuronal damage associated with head
trauma. Approximately two million traumatic brain injuries occur each year in
the United States, with 25% of such injuries requiring hospitalization and about
one percent resulting in death.
 
    Certain medical procedures are associated with an increased risk of stroke.
For example, strokes occur in three to seven percent of coronary artery bypass,
carotid endarterectomy and heart valve replacement surgeries. Mild to severe
central nervous system dysfunction occurs in up to 80% of such procedures. This
is thought to result from multiple micro-strokes caused by the release into the
circulation of numerous tiny blood clots. The Company believes that it might be
possible to lessen the severity of neuronal damage and cognitive impairment
occurring as a result of such procedures by prophylactic treatment with certain
of the Company's neuroprotective compounds.
 
    Because of the importance of glutamate receptor-operated calcium influx in
various neurological disorders, a number of companies are attempting to develop
antagonists of NMDA receptor-channels as therapeutics. Most of these compounds
have been associated with significant adverse side effects such as symptoms of
psychosis. There are currently no effective neuroprotective therapeutics
available that act to slow or stop the progression of brain damage once a stroke
or head trauma has occurred.
 
    PRECLINICAL DEVELOPMENT STATUS.  Systemic administration of the Company's
proprietary class of lead compounds, particularly NPS 1506, has demonstrated
significant neuroprotectant activity in certain animal models of ischemic stroke
and head trauma. In these animal studies, significant neuroprotectant activity
was still observed when administration of the compound was delayed for two hours
following the ischemic event. In addition, the Company's compounds have not
exhibited PCP-like effects in a variety of in vitro and in vivo animal studies
intended to identify PCP-like effects. The Company plans to file an IND and
begin human clinical Phase I trials before June 30, 1997. There can be no
assurance that NPS 1506 or any of the other lead compounds will enter clinical
development, will prove safe and effective, meet applicable regulatory standards
or be successfully marketed. See "Risk Factors--Early Stage of Product
Development."
 
DISCOVERY PROGRAMS
 
    The Company is actively engaged in several other discovery programs which
seek to identify new molecular targets for the development of new drugs. These
discovery programs are extensions of the Company's discoveries in calcium
receptors and ion channels.
 
METABOTROPIC GLUTAMATE RECEPTORS
 
    Metabotropic glutamate receptors ("mGluRs") are structurally distinct from
glutamate receptor-operated calcium channels like the NMDA receptor-operated
calcium channel and are related in structure to the parathyroid cell calcium
receptor. The Company believes that its experience in the discovery and
development of drug candidates which act at calcium receptors provides the
Company with certain advantages in the mGluR field. mGluRs are involved in the
regulation of a number of important brain functions, and the Company believes
that drugs which target specific mGluRs may be useful in treating
 
                                       9
<PAGE>
various neurological disorders, including neurodegenerative disorders such as
Alzheimer's disease, cognitive dysfunction, anxiety and certain psychiatric
disorders.
 
    NPS scientists have discovered proprietary small molecules which are active
at mGluRs. In addition, NPS scientists have cloned a novel mGluR and have
developed proprietary assays and cell lines for use in the Company's mGluR
program. The Company's compounds have substantially different structures than
existing compounds active at mGluRs which the Company believes could allow them
to reach the brain more efficiently. Medicinal chemistry efforts with these lead
compounds are ongoing at the Company.
 
ADDITIONAL CALCIUM RECEPTOR THERAPEUTICS
 
    The Company is actively pursuing drug candidates which target calcium
receptors in distinct tissues for the treatment of several disorders. In the
kidney, for example, NPS and its collaborators have shown that calcium receptors
are abundantly expressed in certain cells which regulate the excretion and
reabsorption of calcium, magnesium and certain electrolytes. Calcium receptors
are also expressed in cells that regulate excretion and reabsorption of water in
the kidney. The Company believes that these calcium receptors participate in the
regulation of mineral, electrolyte and fluid balance in the body and that drugs
which target calcium receptors in the kidney may provide therapies for abnormal
states of ion and water retention. Such abnormal states occur in congestive
heart failure, for example, and in nephrolithiasis (kidney stone formation).
 
INORGANIC ION RECEPTORS
 
    The Company believes that calcium receptors are representative of a new and
important class of cell surface receptors, receptors that are able to detect and
respond to changes in the concentration of inorganic ions such as sodium,
chloride, potassium and phosphate. It has been known for some time that many
different tissues respond to changes in the level of such ions. For example,
Vitamin D synthesis and certain critical kidney functions are regulated in part
by changes in circulating phosphate ion concentrations. Similarly, certain
functions of the adrenal gland are affected by changes in potassium levels, and
the maintenance of fluid concentrations by the brain may depend on the
activation of sodium receptors. Therapeutic agents that act directly on
receptors for other ions could provide effective treatments for many disease
states. As a result, inorganic ion receptors are attractive targets for the
development of novel therapeutic agents. The Company's scientists and its
collaborators are actively engaged in research to clone new inorganic ion
receptors, to determine their roles in human physiology and disease, and to
discover new drug candidates which act selectively on such inorganic ion
receptors.
 
NEURONAL ION CHANNELS
 
    The Company has isolated, from its unique library of arthropod venoms,
various peptides that target neuronal ion channels, in particular, certain
calcium channels and certain potassium channels. The Company believes that its
discoveries of such peptide leads provide the Company with opportunities for the
discovery of drugs to treat various neurological disorders. For example, one
such peptide modulates a particular neuronal potassium channel by binding at a
previously unknown site on this channel. Blocking this potassium channel in
nerve cells is known to enhance specific neural activities, especially the
prolongation of neuronal signals that may have a potential palliative effect in
disorders such as Parkinson's disease, Alzheimer's disease and multiple
sclerosis.
 
DRUG DISCOVERY TECHNOLOGIES
 
    The Company's approach to the discovery of novel drugs is to identify new
drug targets and to identify small molecules which modulate the activities of
these targets (or of previously identified targets) in ways that provide unique
and effective therapies. NPS has pioneered the use of various whole cell and
tissue functional screens in its drug discovery programs. The Company believes
that its functional screens
 
                                       10
<PAGE>
substantially enhance its abilities to discover new receptors and ion channels
and new drug candidates which modulate the activities of specific receptors or
ion channels through novel mechanisms. Functional screens were of critical
importance, for example, in the Company's discovery of calcimimetic compounds
that modulate calcium receptor function.
 
    The Company also utilizes a unique library of invertebrate venoms. These
venoms are isolated from a wide variety of species of spiders, scorpions,
centipedes, parasitic wasps and other invertebrates collected from around the
world. Lead molecules from this library have been useful in the discovery phases
of many of the Company's programs. Examples include the first-generation, small
molecule Araxin ("arachnid toxin") compounds which identified a novel site on
NMDA receptor-channels, peptide leads being used in the Company's ion channel
discovery efforts, and early calcium receptor agonist leads.
 
COLLABORATIVE RESEARCH AND LICENSE AGREEMENTS
 
    NPS is pursuing research and product development both on an independent
basis and in collaboration with others. NPS currently has collaborative research
and/or license agreements with Amgen, Kirin, SmithKline Beecham, Brigham and
Women's, the State University of New York at Buffalo, the University of Texas in
Galveston and several other academic institutions. See "Risk Factors--Dependence
on Collaborative Relationships."
 
AMGEN INC.
 
    In March 1996, the Company entered into a development and license agreement
with Amgen effective December 1995 (the "Amgen Agreement") which grants Amgen
the exclusive right to develop and commercialize a drug for the treatment of HPT
(and other indications other than osteoporosis) worldwide excluding Japan,
China, North and South Korea and Taiwan (the "Kirin Territory"). The license
includes NPS R-568 and certain other compounds. Under the terms of the Amgen
Agreement, NPS may receive from Amgen up to an aggregate of $43.5 million in
license fee, equity purchases and milestone payments plus royalties from any
future product sales in exchange for exclusive rights to develop, manufacture
and sell compounds for the treatment of HPT worldwide, excluding the Kirin
Territory. Amgen has assumed full control, authority and responsibility for
conducting, funding and pursuing all aspects of the development, submissions for
regulatory approvals, manufacture and commercialization of NPS R-568 and certain
related compounds worldwide, other than in the Kirin Territory ("Amgen
Territory") including conducting clinical trials and making regulatory
submissions. Amgen has paid NPS an initial non-refundable license fee of $10.0
million and purchased one million shares of Common Stock at the price of the
Company's Common Stock in November 1995 when the Amgen Agreement was negotiated
for an aggregate purchase price of $7.5 million. The balance of the $43.5
million includes up to $26.0 million payable to NPS upon the achievement of
specific development milestones. NPS has the option to participate with Amgen,
under the direction of Amgen, in the clinical development of a drug for primary
HPT. Amgen is required to reimburse NPS for such participation which is limited
to a total cost of $400,000 per year for a maximum time period of five years.
Amgen may terminate the Amgen Agreement for any reason upon 90 days written
notice. Termination of the Amgen Agreement will result in the reversion to NPS
of its technology, patent and commercialization rights in the Amgen Territory.
There can be no assurance that Amgen will not terminate the Amgen Agreement. In
the event of termination of the license agreement with Kirin, Amgen would
receive worldwide rights to develop and commercialize NPS R-568 and other HPT
compounds. NPS is actively working with Amgen and Kirin to discover, identify
and characterize back-up and second generation compounds. See "Risk
Factors--Dependence on Collaborative Research and License Relationships."
 
KIRIN BREWERY COMPANY, LIMITED
 
    In June 1995, the Company entered into a five-year collaborative research
and license agreement with Kirin (the "Kirin Agreement") to develop and
commercialize the Company's NPS R-568 and other
 
                                       11
<PAGE>
compounds for the treatment of HPT in the Kirin Territory. Under the terms of
the Kirin Agreement, NPS may receive from Kirin up to an aggregate of $25.0
million in license fee, research support and milestone payments plus royalties
from any future product sales in exchange for exclusive rights to develop,
manufacture and sell NPS R-568 and certain other compounds for the treatment of
HPT in the Kirin Territory. Kirin is responsible for conducting clinical trials
and obtaining regulatory approvals in the Kirin Territory. Kirin has paid NPS an
initial, non-refundable license fee of $5.0 million and committed to make $7.0
million in research payments for research concerning NPS R-568 and back-up and
second generation compounds over five years. The Kirin research support payments
are $500,000 per quarter through June 1997 and $250,000 per quarter over the
remaining three years. The remaining $13.0 million is payable to NPS upon
achievement of specific development milestones in the United States and the
Kirin Territory. In October 1996, the Company received its first milestone
payment from Kirin in the amount of $2.0 million for the start of clinical
trials in Japan. Kirin is required to pay all costs of developing and
commercializing products within the Kirin Territory and will pay royalties to
NPS on any product sales. NPS is actively working with Kirin and Amgen to
discover, identify and characterize back-up and second generation compounds.
Kirin may terminate the Kirin Agreement for any reason upon 90 days written
notice. Termination of the Kirin Agreement will result in Amgen receiving
worldwide rights to develop and commercialize NPS R-568 and other HPT compounds.
There can be no assurance that Kirin will not terminate the Kirin Agreement. See
"Risk Factors--Dependence on Collaborative Research and License Relationships."
 
SMITHKLINE BEECHAM CORPORATION
 
    In November 1993, NPS entered into a three-year collaborative research and
license agreement with SmithKline Beecham (the "SmithKline Agreement") to
collaborate on the discovery, development and marketing of drugs to treat
osteoporosis and other bone metabolism disorders. Under the SmithKline
Agreement, SmithKline Beecham has the exclusive license to develop and market
worldwide any calcium receptor-active compounds developed under the SmithKline
Agreement that are useful for treating osteoporosis and other bone metabolism
disorders, excluding HPT. In addition, SmithKline Beecham has a six-month right
of first negotiation of a research and license agreement with NPS with respect
to any compounds relating to osteoporosis not covered under the SmithKline
Agreement. Once compounds have been selected for development, SmithKline Beecham
has agreed to conduct and fund all development of such products, including all
human clinical trials and regulatory submissions. NPS has the right to co-
promote with SmithKline Beecham any resulting products in the United States. In
1992, S.R. One, an affiliate of SmithKline Beecham, purchased $2.0 million of
the Company's Preferred Stock. In 1993, at the time NPS entered into the
SmithKline Agreement, S.R. One purchased an additional $7.0 million in equity of
the Company and it acquired $495,000 of Common Stock in the Company's initial
public offering. All of the Preferred Stock was converted into Common Stock upon
the closing of the Company's initial public offering.
 
    Under the terms of the SmithKline Agreement, in addition to the $7.0 million
equity purchase, SmithKline Beecham paid the Company a $6.0 million
non-refundable license fee and agreed to make additional payments to the Company
upon the achievement of specific milestones. A $3.0 million milestone payment
was made in January 1996. In July 1995 the Company began receiving payments from
SmithKline Beecham to support the Company's research efforts and has recognized
$4.3 million through 1996. In October 1996, the research term of the SmithKline
Agreement was extended for an additional one year period through October 1997.
Research support payments are expected to be approximately $475,000 per quarter
through October 1997. NPS is entitled to royalties on sales of products for
osteoporosis and other bone metabolism disorders developed by SmithKline Beecham
under the SmithKline Agreement and a share of the profits from any co-promotion
of such products. The SmithKline Agreement may be terminated by SmithKline
Beecham upon 30 days written notice, with NPS having the right to extend the
SmithKline Agreement for an additional period of time, provided that drug
marketing has commenced. Funded research under the SmithKline Agreement will
terminate in October 1997. Under certain
 
                                       12
<PAGE>
circumstances, NPS has the right to terminate the SmithKline Agreement after
October 1997. Termination of the SmithKline Agreement will result in reversion
to NPS of its technology, commercialization and patent rights in the licensed
field of osteoporosis and other bone and mineral disorders as well as all
additional technology developed in the course of the collaboration. There can be
no assurance that SmithKline Beecham will not terminate the SmithKline Agreement
or that funded research will be extended upon its termination in October 1997.
See "Risk Factors--Dependence on Collaborative Research and License
Relationships."
 
THE BRIGHAM AND WOMEN'S HOSPITAL, INC.
 
    In February 1993, NPS entered into two agreements with Brigham and Women's,
a sponsored collaborative research agreement (the "Brigham Research Agreement")
and a patent license agreement (the "Brigham License Agreement"). Brigham and
Women's, an affiliate of Harvard University Medical School, is a leading
research group in the area of calcium receptors. During the three-year period
from February 1993 through January 1996, NPS paid license fees and made research
support and milestone payments to Brigham and Women's totaling approximately
$1.0 million. In February 1996, the Company reached an agreement with Brigham
and Women's to extend the Brigham Research Agreement. This agreement was further
amended effective March 1, 1997, to update the amount of research support
payments to be made by NPS for the final year of the agreement. Under the terms
of the extension, NPS has agreed to continue funding research on calcium
receptors and other inorganic ion receptors at Brigham and Women's through
February 1998. The extended Brigham Research Agreement, as amended, calls for
NPS to make research support and advance royalty payments of $645,000 to Brigham
and Women's during the period from February 1996 through February 1998. Of this,
$430,000 has been paid through 1996. The Brigham License Agreement grants NPS an
exclusive license to calcium receptor and inorganic ion receptor technology
arising under the Brigham Research Agreement. The Brigham Research Agreement
also grants NPS a right of first negotiation for exclusive license rights to any
other patentable subject matter arising out of the sponsored research. NPS also
has agreed to pay Brigham and Women's a royalty on sales of any products covered
by an issued patent under the Brigham License Agreement and to promote sales of
any licensed products for HPT for which the Company receives regulatory
approval.
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
    Periodically the Company files patent applications to protect technology,
inventions and improvements which the Company believes are important to the
development of its business. The Company also relies on trade secrets, know-how,
continuing technological innovations and licensing opportunities to develop and
maintain its competitive position.
 
    The Company files patent applications in its own name, and when appropriate,
it has filed, and expects to continue to file, applications jointly with its
collaborators. These patent applications cover compositions of matter, methods
of treatment, methods of discovery, use of novel compounds and novel modes of
action, and recombinantly expressed receptors and gene sequences which are
believed by the Company to be important in its research and development
activities. None of the Company's principal proprietary rights, including rights
related to process, compounds, use and technique related to its calcium receptor
science and NMDA receptor-channel technology, are protected by issued patents in
the Company's principal markets. The Company believes that its pending patent
applications in the fields of calcium receptors, inorganic ion receptors, mGluRs
and NMDA receptor-channels and compounds active at the same give the Company a
competitive advantage. The Company intends to file additional patent
applications as appropriate relating to its technology and to specific products
of the Company.
 
    The patent positions of pharmaceutical and biotechnology firms, including
the Company, are uncertain and involve complex legal and factual questions. In
addition, the scope of the claims in a patent application can be significantly
modified during prosecution before the patent is issued. Consequently, the
Company does not know whether any of its applications will result in the
issuance of patents or, if any
 
                                       13
<PAGE>
patents are issued, whether they will provide significant proprietary protection
or will be circumvented or invalidated. Generally, patent applications in the
United States are maintained in secrecy until patents issue and publication of
discoveries in the scientific or patent literature often lag behind actual
discoveries. In addition, no assurance can be given that, even if published, the
Company is aware of all such literature. Accordingly, the Company cannot be
certain that the named inventors were the first to invent or that the Company is
the first to pursue patent coverage for such inventions. Moreover, the Company
may have to participate in interference proceedings declared by the United
States Patent and Trademark Office to determine priority of invention, which
could result in substantial cost to the Company, even if the eventual outcome is
favorable to the Company. There can be no assurance that the Company's pending
patent applications, if issued, would be held valid. An adverse outcome could
subject the Company to significant liabilities to third parties, could require
disputed rights to be licensed from third parties or require the Company to
cease or modify its use of such technology. Additionally, many of the Company's
foreign patent applications have been published as part of the patent
prosecution process in such countries. Protection of the rights revealed in such
published patent applications can be complex, costly and uncertain. See "Risk
Factors--Uncertainty of Protection of Patents and Proprietary Technology."
 
    The development of therapeutic products for applications in the Company's
product fields is intensely competitive. A number of pharmaceutical companies,
biotechnology companies, universities and research institutions have filed
patent applications or received patents in these and related fields. Some of
these applications or patents may limit or preclude the Company's applications
and could result in a significant reduction of the coverage of the Company's
patents, if issued.
 
    NPS also relies on trade secrets and contractual arrangements to protect its
trade secrets. There can be no assurance that these agreements will be adequate,
that they will not be breached, that the Company would have adequate remedies
for any breach or that the Company's trade secrets will not otherwise become
known or be independently discovered by competitors.
 
    Much of the know-how important to the Company's technology and many of its
processes are dependent upon the knowledge, experience and skills of key
scientific and technical personnel and are not the subject of pending patent
applications or issued patents. To protect its rights to its know-how and
technology, the Company requires all employees, consultants, advisors and
collaborators to enter into confidentiality agreements that prohibit the
unauthorized use and restrict the disclosure of confidential information, and
require disclosure and assignment to the Company of ideas, developments,
discoveries and inventions made by them. There can be no assurance that these
agreements will effectively prevent disclosure of the Company's confidential
information or will provide meaningful protection for the Company's confidential
information if there is unauthorized use or disclosure. It must also be
recognized that competitors may develop substantially equivalent know-how and
technology.
 
    In connection with certain research in the field of calcium and other ion
receptors, NPS has sponsored research by various university and government
laboratories. For example, the Company has executed a license agreement and a
research agreement regarding research in the area of calcium and other ion
receptors with Brigham and Women's. See "Collaborative Research and Licensing
Agreements--The Brigham and Women's Hospital, Inc."
 
    The Company has also sponsored work at other government and academic
laboratories for various evaluations, assays, screenings and tests of its
natural products library and lead compounds in the central nervous system field.
Generally, under these agreements the Company funds the work of investigators in
exchange for the results of the specified works and the right or option to a
license to any patentable inventions that may result in designated areas.
Generally, if the sponsored work produces patentable subject matter, the Company
has the first right to negotiate for license rights therein. Any resulting
license would be expected to require the Company to pay royalties on net sales
of licensed products. There can be no assurance that any such inventions will
arise, that any patent applications thereon will be filed or, if filed, that any
patents will issue, that any license thereon can be negotiated, or that any
license agreement would give the Company valuable rights.
 
                                       14
<PAGE>
MANUFACTURING
 
    NPS anticipates that all of its products will be made by synthetic chemical
manufacturing techniques. As such, the Company believes the compounds can be
precisely defined and characterized and should generally have relatively low
manufacturing costs compared to recombinant proteins produced by the
fermentation methods common to currently available biotechnology products.
 
    NPS has no manufacturing facilities. Under the Amgen, Kirin and SmithKline
Agreements, each of such Licensee's is responsible for the manufacture of the
applicable product. The Company relies on other manufacturers to produce its
proprietary compounds for research and development activities and in sufficient
quantities for preclinical and clinical purposes. The proposed pharmaceutical
products under development by the Company have never been manufactured on a
commercial scale, and there can be no assurance that such products can be
manufactured at a cost or in quantities to make them commercially viable. If the
Company were unable to contract for sufficient supply of its compounds on
acceptable terms, or if it should encounter delays or difficulties in its
relationships with manufacturers, the Company's preclinical and clinical testing
schedule would be delayed. Such delay might postpone the submission of products
for regulatory approval or the market introduction and subsequent sales of such
products, which would have a materially adverse effect on the Company. Moreover,
contract manufacturers that the Company may use must adhere to Good
Manufacturing Practices (cGMP) regulations enforced by the FDA through its
facilities inspection program.
 
GOVERNMENT REGULATION
 
    The production and marketing of the Company's product candidates and its
research and development activities are subject to regulation for safety,
efficacy and quality by numerous governmental authorities in the United States
and other countries. In the United States, drugs are subject to rigorous FDA
regulation. The Federal Food, Drug and Cosmetic Act, as amended, and the
regulations promulgated thereunder, and other federal and state statutes and
regulations govern, among other things, the testing, manufacture, safety,
efficacy, labeling, storage, record keeping, approval, advertising and promotion
of the Company's products. Product development and approval within this
regulatory framework take a number of years and involve the expenditure of
substantial resources.
 
    The steps required before a pharmaceutical agent may be marketed in the
United States include: (i) preclinical laboratory tests, animal pharmacology and
toxicology studies and formulation studies; (ii) the submission to the FDA of an
IND for human clinical testing, which must become effective before human
clinical trials commence; (iii) adequate and well-controlled human clinical
trials to establish the safety and efficacy of the drug; (iv) the submission of
a New Drug Application ("NDA") to the FDA; and (v) FDA approval of the NDA prior
to any commercial sale or shipment of the drug. In addition to obtaining FDA
approval for each product, each domestic drug manufacturing establishment must
be registered with, and approved by, the FDA under cGMP regulations. Domestic
drug manufacturing establishments are subject to regular inspections by the FDA
and must comply with cGMP regulations. To supply products for use in the United
States, foreign manufacturing establishments must comply with cGMP regulations
and are subject to periodic inspection by the FDA or by corresponding regulatory
agencies in their home countries under reciprocal agreements with the FDA.
 
    Preclinical studies include the laboratory evaluation of IN VITRO
pharmacology, product chemistry and formulation, as well as animal studies to
assess the potential safety and efficacy of the product. Compounds must be
formulated according to cGMP, and preclinical safety tests must be conducted by
laboratories that comply with FDA regulations regarding Good Laboratory
Practices. The results of the preclinical tests are submitted to the FDA as part
of an IND and are reviewed by the FDA prior to the commencement of human
clinical trials. Unless the FDA objects to an IND, the IND will usually become
effective 30 days following its receipt by the FDA. There can be no assurance
that submission of an IND will result in FDA authorization to commence clinical
trials.
 
                                       15
<PAGE>
    Clinical trials involve the administration of the investigational new drug
to healthy volunteers and to patients under the supervision of a qualified
principal investigator. Clinical trials are conducted in accordance with Good
Clinical Practices under protocols that detail the objectives of the study, the
parameters to be used to monitor safety and the efficacy criteria to be
evaluated. Each protocol must be submitted to the FDA as part of the IND.
Further, each clinical study must be conducted under the auspices of an
Institutional Review Board ("IRB") at the institution at which the study will be
conducted. The IRB will consider, among other things, ethical factors, the
safety of human subjects and the possible liability of the institution.
 
    Clinical trials typically are conducted in three sequential phases, which
may overlap. In Phase I, the initial introduction of the drug into healthy
subjects, the drug is tested for safety (adverse effects), dosage tolerance,
metabolism, distribution, excretion and pharmacodynamics (clinical
pharmacology). Phase II involves studies in a limited patient population to: (i)
determine the efficacy of the drug for specific, targeted indications; (ii)
determine dosage tolerance and optimal dosage; and (iii) identify possible
adverse effects and safety risks. When a compound is found to be effective and
to have an acceptable safety profile in Phase II evaluations, Phase III trials
are undertaken to evaluate further clinical efficacy and to test further for
safety within an expanded patient population at geographically dispersed
clinical study sites. There can be no assurance that Phase I, Phase II or Phase
III testing will be completed successfully within any specific time period, if
at all, with respect to any of the Company's products subject to such testing,
including NPS R-568. Furthermore, the Company, its collaborators, Licensees or
the FDA may suspend clinical trials at any time if they feel that the subjects
or patients are being exposed to an unacceptable health risk. See "Risk
Factors--Government Regulation; No Assurance of Regulatory Approval."
 
    The results of the pharmaceutical development, preclinical studies and
clinical studies are submitted to the FDA in the form of an NDA for approval of
the marketing and commercial shipment of the drug. The testing and approval
process is likely to require substantial time and effort, and there can be no
assurance that any approval will be granted on a timely basis, if at all. The
FDA may deny an NDA if applicable regulatory criteria are not satisfied, require
additional testing or information, or require post-marketing testing and
surveillance to monitor the safety of the Company's products if the FDA does not
view the NDA as containing adequate evidence of the safety and efficacy of the
drug. Notwithstanding the submission of such data, the FDA may ultimately decide
that the application does not satisfy its regulatory criteria for approval.
Moreover, if regulatory approval of a drug is granted, such approval may entail
limitations on the indicated uses for which it may be marketed. Finally, product
approvals may be withdrawn if compliance with regulatory standards is not
maintained or if problems occur following initial marketing.
 
    Among the conditions for NDA approval is the requirement that the
prospective manufacturer's quality control and manufacturing procedures conform
to cGMP, which must be followed at all times. In complying with standards set
forth in these regulations, manufacturers must continue to expend time, money
and effort in the area of production and quality control to ensure full
technical compliance. See "Risk Factors--Government Regulation; No Assurance of
Regulatory Approval."
 
    In addition to regulations enforced by the FDA, the Company is also subject
to regulation under the Occupational Safety and Health Act, the Environmental
Protection Act, the Toxic Substances Control Act, the Resource Conservation and
Recovery Act and other present and future federal, state or local regulations.
The Company's research and development activities involve the controlled use of
hazardous materials, chemicals and various radioactive compounds. Although the
Company believes that its safety procedures for handling and disposing of such
materials comply with the standards prescribed by state and federal regulations,
the risk of accidental contamination or injury from these materials cannot be
completely eliminated. In the event of such an accident, the Company could be
held liable for any damages that result, and any such liability could exceed the
resources of the Company. See "Risk Factors--Risk of Product Liability; Use of
Hazardous Materials."

    Outside the United States, the Company's ability to market a product is
contingent upon receiving a marketing authorization from the appropriate
regulatory authority. This foreign regulatory approval process includes all of
the risks associated with FDA approval set forth above.
 
COMPETITION
 
    NPS and its Licensees are pursuing areas of product development in which the
Company believes there is a potential for extensive technological innovation in
relatively short periods of time. The Company operates in a field in which new
discoveries occur and are expected to occur at a rapid pace. The Company's
competitors may succeed in developing technologies or products that are more
effective than those of the Company or in obtaining regulatory approvals of
their drugs more rapidly than the Company and its collaborative partners, and
could render the Company's products obsolete or noncompetitive. Competition in
the pharmaceutical industry is intense and is expected to continue to increase.
Many of the Company's competitors, including biotechnology and pharmaceutical
companies, are actively engaged in the research and development of products in
the Company's targeted areas, including the fields of HPT, osteoporosis,
neuroprotection and neurological disorders. Many of the Company's competitors
have substantially greater financial, technical, marketing and personnel
resources than the Company. In addition, some of them have considerable
experience in preclinical testing, human clinical trials and other regulatory
approval procedures. Moreover, certain academic institutions, governmental
agencies and other research organizations are conducting research in areas in
which the Company is working. These institutions are becoming increasingly aware
of the commercial value of their findings and are becoming more active in
seeking patent protection and licensing arrangements to collect royalties for
use of technology that they have developed. These institutions may also market
competitive commercial products on their own or through joint ventures and will
compete with the Company in recruiting highly qualified scientific personnel.
There can be no assurance that a pharmacological method of treatment for certain
diseases, such as HPT, will prove to be superior to existing or newly discovered
approaches to the treatment of those diseases. See "Risk Factors--Rapid
Technological Change; Intense Competition."
 
ENVIRONMENTAL LIABILITY
 
    On November 29, 1995, the Company received a letter from the EPA notifying
the Company that it may have incurred liability under section 107(a) of the
Comprehensive Environmental Response, Compensation and Liability Act, as
amended, for two barrels of radioactive waste taken by a third party contractor
to a hazardous and radioactive waste storage, treatment and disposal facility in
Denver, Colorado. Upon the EPA's request, the Company has identified the waste
and has verified that the barrels containing the waste have been removed from
the Denver, Colorado facility. Removal of wastes from the facility and
remediation of soil and groundwater at this site is currently underway. The
ultimate cost of removal and remediation actions and the length of time for such
actions are difficult to estimate. Based upon its inspection of the site, the
Company is of the belief that the barrels containing the waste disposed of by
the Company were neither leaking nor damaged. Although the Company was a small
contributor to the site and the Company believes that there are a number of
other financially responsible contributors, there can be no assurance that the
Company will not be held liable for all or a portion of the cleanup cost or any
other costs or damages associated with this disposal site. See "Risk
Factors--Risk of Product Liability; Use of Hazardous Materials."
 
EMPLOYEES
 
    As of December 31, 1996, NPS employed 90 individuals full-time, 21 of whom
hold Ph.D. or M.D. degrees and 19 of whom hold other advanced degrees.
Approximately 62 full-time employees are engaged in research and development
activities, including a variety of disciplines within the areas of molecular
biology, pharmacology, medicinal chemistry, computer sciences and clinical
development. Approximately 28 full-time employees are employed in finance, legal
and regulatory affairs, market research, corporate
 
                                       17
<PAGE>
development and general administrative activities. None of the Company's
employees is covered by collective bargaining agreements, and management
considers relations with its employees to be good. Additionally, NPS augments
its full-time staff through consulting arrangements with experienced scientists
and managers. The Company's anticipated growth and expansion will require the
hiring of additional management, research and development, and administrative
personnel.
 
RISK FACTORS
 
    EARLY STAGE OF PRODUCT DEVELOPMENT.  The Company was founded in 1986, and
has not completed development of any drugs and does not expect that any drugs
resulting from its or its Licensees' research and development efforts will be
commercially available for several years, if at all. NPS R-568 is the only
product candidate currently in clinical development by the Company and its
Licensees. Clinical trials in humans are necessary to determine whether or not a
compound will be a safe, commercially attractive or effective drug. Results
obtained in preclinical trials are not necessarily indicative of results that
will be obtained in later stages of preclinical development or in human clinical
testing. All product candidates developed by the Company or its Licensees,
including NPS R-568, will require extensive research, development and
preclinical and clinical testing prior to submission of any regulatory
application, as well as a lengthy regulatory approval process. Preclinical and
clinical testing of safety and efficacy takes several years and the time
required to commercialize new drugs cannot be predicted with accuracy. Product
development of new pharmaceuticals is highly uncertain, and unanticipated
developments, clinical or regulatory delays, unexpected adverse side effects or
inadequate therapeutic efficacy could slow or prevent the product development
efforts of the Company and its Licensees, and have a materially adverse effect
on the Company's operations. There can be no assurance that the Company's
current product candidates, including NPS R-568, or any future product
candidates, will advance to clinical trials, prove safe and effective, meet
applicable regulatory standards, be capable of being produced in commercial
quantities at acceptable cost or be successfully marketed. Also, there can be no
assurance that a pharmacological method for the treatment of diseases targeted
by the Company, including HPT, will prove to be superior to non-pharmacological
treatments.
 
    DEPENDENCE ON COLLABORATIVE RESEARCH AND LICENSE RELATIONSHIPS.  The
Company's strategy for the development, clinical testing and manufacturing and
commercialization of certain of its product candidates and the research and
development of new product candidates includes entering into various research,
development and license agreements with corporate partners, licensees and
others. The Company has entered into a license agreement with Amgen pursuant to
which Amgen has assumed full control of the development and commercialization of
a compound for the treatment of HPT in its territory, a collaborative research
and license agreement with Kirin for the development of a compound for the
treatment of HPT in Kirin's Territory and a collaborative research and license
agreement with SmithKline Beecham for research and development in osteoporosis.
The Licensees each have received from NPS certain exclusive rights to
commercialize products developed under their respective agreements, have paid
license fees to NPS and have committed to make milestone payments to NPS upon
achievement of specified goals. The Licensees have agreed to fund the research
or development efforts in HPT and osteoporosis, conduct human clinical testing
of lead compounds, prepare and file submissions for regulatory approval and pay
royalties on any resulting products. Because the Company has granted exclusive
development, commercialization and marketing rights to the Licensees in the
fields of HPT and osteoporosis, the success of its existing HPT and osteoporosis
programs is dependent upon the efforts of the Licensees. There can be no
assurance that the Licensees will perform their obligations under their
respective agreements, that they will successfully develop or proceed to market
any products under these agreements, or that the Company will ever receive any
royalties or milestone or research support payments under these agreements, any
of which could have a material adverse effect on the business of the Company.
Furthermore, there can be no assurance that business conflicts will not arise
between the Licensees over rights to existing compounds or future compounds with
respect to certain indications. The Company's collaborative research and license
agreements, including the agreements with the Licensees, generally provide that
they may be terminated
 
                                       18
<PAGE>
under a variety of circumstances upon prior written notice. If any of the
Licensees terminates or breaches its agreement, such termination or breach may
have a material adverse effect on the Company's operations. Furthermore, there
can be no assurance that present or future collaborators will not pursue
existing or alternative technologies in preference to treatments being developed
in collaboration with the Company.
 
    NPS also intends to seek additional collaborative or license arrangements to
develop and commercialize other product candidates. Many of the Company's
competitors are similarly seeking to develop or expand their collaborative and
license arrangements with pharmaceutical companies. The success of these efforts
by the Company's competitors could have an adverse impact on the Company's
ability to form future collaborative arrangements and maintain existing ones.
There can be no assurance that the Company will be able to negotiate acceptable
collaborative agreements in the future or that efforts under any such
collaborative agreements will be successful. To the extent that the Company
chooses not to or is unable to enter into future collaborative agreements, it
would experience increased capital requirements to undertake research,
development and marketing of its product candidates at its own expense. In
addition, the Company may encounter significant delays in introducing its
product candidates into certain markets or find that the development,
manufacture or sale of its product candidates in such markets is adversely
affected by the absence of such collaborative agreements.
 
    LACK OF PRODUCT SALES; HISTORY OF OPERATING LOSSES.  Substantially all of
the Company's revenues to date have come from collaborative research and license
agreements with the Licensees. Aside from the incidental revenues from the sale
of research chemicals, no revenues have been generated from product sales. Other
working capital has come from equity and debt financings. NPS has incurred
cumulative losses through December 31, 1996 of $14.4 million, net of cumulative
revenues from research and license agreements of $42.7 million. The Company
expects to incur significant operating losses over at least the next several
years as the Company continues and expands its research and development and
preclinical and clinical testing activities. The Company expects that losses
will fluctuate from quarter to quarter and that such fluctuations may be
substantial. The Company's ability to achieve profitability depends in part upon
its Licensees' ability to complete development of NPS R-568 and identify and
develop back-up and later generation compounds, the Company's ability to
develop, alone or with others, other product candidates, obtain required
regulatory approvals and manufacture and successfully market such products, of
which there can be no assurance. As such, there can be no assurance that the
Company will be able to achieve profitability on a sustained basis, if at all.
 
    GOVERNMENT REGULATION; NO ASSURANCE OF REGULATORY APPROVAL.  The research
and development activities of the Company, as well as the investigation,
manufacture, distribution and marketing of therapeutic products, are subject to
extensive regulation by numerous governmental authorities in the United States
and other countries. Prior to marketing in the United States, a drug must
undergo rigorous preclinical and clinical testing and an extensive regulatory
approval process implemented by the FDA under federal law, including the Federal
Food, Drug and Cosmetic Act, as amended. Receipt of such regulatory approval
involves, among other things, satisfying the FDA that the product is both safe
and effective. Typically, this process takes several years or more depending
upon the type, complexity and novelty of the product and the nature of the
disease or other indication to be treated and requires the expenditure of
substantial resources. Preclinical studies must be conducted in conformance with
the FDA's Good Laboratory Practice regulations. Clinical testing must meet
requirements for Institutional Review Board oversight and informed consent by
clinical trial subjects and patients, as well as FDA prior review, oversight and
the FDA's Good Clinical Practice requirements. Clinical trials may require large
numbers of test subjects. Furthermore, the Company or the FDA may suspend
clinical trials at any time if either believes that the subjects participating
in such trials are being exposed to unacceptable health risks, including
undesirable or unintended side effects. While certain of the Company's employees
have some experience in conducting and managing the clinical testing necessary
to obtain regulatory approval, the Company has conducted only limited clinical
trials of one of its product candidates to date and anticipates that it will
need to either
 
                                       19
<PAGE>
rely on its collaborative partners, licensees and outside consultants or attract
and retain additional employees with expertise in this area.
 
    Before receiving FDA approval to market a product, NPS may have to
demonstrate that such product represents an improved form of treatment compared
to existing therapies. Data obtained from preclinical and clinical activities
are susceptible to varying interpretations which could delay, limit or prevent
regulatory approvals. In addition, delays or rejections may be encountered based
upon additional government regulation from future legislation or administrative
action or changes in FDA policy during the period of product development,
clinical trials and FDA regulatory review. If regulatory approval of a product
is granted, such approval will be limited to those disease states and conditions
for which the product is useful, as demonstrated through clinical studies.
Furthermore, approval may entail ongoing requirements for post-marketing
studies. Even if such regulatory approval is obtained, a marketed product, its
manufacturer and its manufacturing facilities are subject to continual review
and periodic inspections. The regulatory standards for current Good
Manufacturing Practices ("cGMP") are currently being applied stringently by the
FDA. Discovery of previously unknown problems with a product, manufacturer or
facility may result in restrictions on such product or manufacturer, including
costly recalls or even withdrawal of the product from the market. There can be
no assurance that any compound developed by the Company alone or in conjunction
with others will prove to be safe and effective in clinical trials and will meet
all of the applicable regulatory requirements needed to receive marketing
approval.
 
    RAPID TECHNOLOGICAL CHANGE; INTENSE COMPETITION.  NPS is pursuing areas of
product development in which the Company believes there is a potential for
extensive technological innovation in relatively short periods of time. The
Company operates in a field in which new discoveries occur and are expected to
occur at a rapid pace. The Company's competitors may succeed in developing
technologies or products that are more effective than those of the Company or in
obtaining regulatory approvals of their drugs more rapidly than the Company and
its collaborative partners and licensees. Such success could render the
Company's products obsolete or non-competitive and have a material adverse
effect on the Company. Competition in the pharmaceutical and biotechnology
industry is intense and is expected to continue to increase. Many of the
Company's competitors, including biotechnology and pharmaceutical companies, are
actively engaged in the research and development of products in the Company's
targeted areas, including the fields of HPT, osteoporosis, neuroprotection and
neurological disorders. Many of the Company's competitors have substantially
greater financial, technical, marketing and personnel resources than the Company
as well as considerable experience in preclinical testing, human clinical trials
and other regulatory approval procedures. Moreover, certain academic
institutions, governmental agencies and other research organizations are
conducting research in areas in which the Company is working. These institutions
are becoming increasingly aware of the commercial value of their findings and
are becoming more active in seeking patent protection and licensing arrangements
to collect royalties for use of technology that they have developed. These
institutions may also market competitive commercial products on their own or
through joint ventures and will compete with the Company in recruiting highly
qualified scientific personnel.
 
    UNCERTAINTY OF PROTECTION OF PATENTS AND PROPRIETARY TECHNOLOGY.  The
Company's success depends, in part, on its ability to obtain patents, maintain
trade secret protection and operate without infringing on the proprietary rights
of third parties. Because the patent positions of biotechnology and
pharmaceutical companies can be highly uncertain and frequently involve complex
legal and factual questions, the breadth of claims allowed in biotechnology and
pharmaceutical patents or their enforceability cannot be predicted.
 
    None of the Company's principal proprietary rights, including rights related
to process, compounds, use and technique related to its calcium receptor science
and NMDA receptor-channel technology, are protected by issued patents in the
Company's principal potential markets. No assurance can be given that patents
will issue from any of the Company's current or anticipated patent applications
or that such patent applications will allow the Company to preclude others from
practicing some or all of the art described in the publicly available versions
of these pending patent applications either before such patent applications
issue as patents or after such patent applications issue as patents. Generally,
patent applications in the
 
                                       20
<PAGE>
United States are maintained in secrecy until patents issue and publication of
discoveries in scientific or patent literature often lag behind actual
discoveries. No assurance can be given that, even if published, the Company is
aware of all such literature. Accordingly, the Company cannot be certain that
the named inventors in its patent applications were the first to invent, or that
the Company is the first to pursue patent coverage for such inventions. If
patents do issue, there can be no assurance that the claims allowed will be
sufficiently broad to protect the Company's technology or to prevent
competition. No assurance can be given that any patents issued to the Company
will not be challenged, invalidated or circumvented or that rights granted
thereunder will provide competitive advantages to NPS. Moreover, the Company may
have to participate in interference proceedings declared by the United States
Patent and Trademark Office to determine priority of invention, which could
result in substantial cost to the Company, even if the eventual outcome is
favorable to the Company. If certain of the Company's patent applications fail
to issue or are successfully challenged, particularly those related to its
calcium receptor science and NMDA receptor-channel technology, it may have a
material adverse effect on the Company's operations or its ability to maintain
or establish collaborations. Furthermore, there can be no assurance that others
will not independently develop similar products, duplicate any of the Company's
products or design around the patented products or technology developed by NPS.
There can also be no assurance that any products developed by NPS will not be
found to infringe patents held by third parties, or that, in such cases,
licenses from such third parties would be available on commercially attractive
terms, if at all. If NPS does not obtain such licenses, it could encounter
delays in product market introductions or could find that it is unable to
develop, manufacture or sell its products requiring such licenses. In addition,
the Company could incur substantial costs in defending lawsuits brought against
NPS on such patents or in prosecuting lawsuits by NPS against another party.
Additionally, many of the Company's foreign patent applications have been
published as part of the patent prosecution process in such countries.
Protection of the rights revealed in such published patent applications can be
complex, costly and uncertain.
 
    The development of therapeutic products for applications in the Company's
product fields is intensely competitive. A number of pharmaceutical companies,
biotechnology companies, universities and research institutions have filed
patent applications or received patents in these and related fields. Some of
these applications or patents may limit or preclude the Company's applications
and could result in a significant reduction of the coverage of the Company's
patents, if issued.
 
    NPS also relies on trade secrets and proprietary know-how, which it seeks to
protect, in part, by confidentiality agreements with its corporate
collaborators, licensees, employees and consultants. NPS expects to continue to
rely on trade secrets and know-how to protect certain aspects of its
technologies. The Company believes it has, and can maintain, a competitive
advantage through its use of written confidential disclosure agreements and
invention assignment provisions with its employees, consultants, advisors and
potential and actual collaborators and licensees. Nonetheless, no assurance can
be given that these agreements will provide meaningful protection for the
Company's trade secrets or proprietary know-how as a result of an unauthorized
use or disclosure in the public domain. There can be no assurance that these
agreements will not be breached, that NPS would have adequate remedies for any
breach, or that the Company's trade secrets will not otherwise become known or
be independently discovered by competitors.
 
    DEPENDENCE ON THIRD PARTIES FOR MANUFACTURING.  To be successful, the
Company's products, if successfully developed, must be manufactured in
commercial quantities in accordance with regulations prescribed by the FDA and
at acceptable costs. NPS does not have the capability to manufacture products
under cGMP regulations prescribed by the FDA and does not intend to develop such
a capability in the near future. Accordingly, the Company anticipates that, for
the foreseeable future, it will pursue a strategy of seeking production
capability from corporate collaborators, licensees or contract manufacturers.
There can be no assurance that the Company's current or prospective corporate
collaborators, licensees or contract manufacturers will be able to manufacture
any developed compounds on a commercial scale or that any collaborator, licensee
or manufacturer will be able to manufacture products in quantities or at prices
which will be commercially viable or beneficial for the Company. The Licensees
are responsible for manufacturing any products developed under their respective
agreements with the Company. If the Company or its
 
                                       21
<PAGE>
collaborators and licensees encounter difficulty in obtaining third-party
manufacturing on commercially acceptable terms, their ability to commercialize
products may be delayed or foreclosed. Moreover, any manufacturer of the
Company's products must adhere to cGMP regulations enforced by the FDA through
its facilities inspection program. If these facilities cannot pass a
pre-approval or periodic plant inspection, FDA approval of the product will not
be granted or sale of the product may be barred.
 
    Presently, the Company relies on contract manufacturers to produce its
proprietary compounds for development activities and in sufficient quantities
for preclinical and clinical purposes. If the Company were unable to contract
for sufficient supply of its compounds on acceptable terms, or if it should
encounter delays or difficulties in its relationships with manufacturers, the
Company's preclinical and human clinical testing schedule would be delayed. Such
delay would adversely affect the schedule for submission of products for
regulatory approval and the market introduction and subsequent sales of such
products, which would have a materially adverse effect on the Company.
 
    FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING.  The Company has
incurred negative cash flows from operations since its inception. Substantial
expenditures will be required to enable NPS to conduct existing and planned
preclinical studies and clinical trials, to manufacture or to have manufactured
and to market products from current research and development efforts, and to
continue research and development activities. The Company anticipates that its
existing capital resources, including research and development support payments
from existing collaborations will be sufficient to enable it to maintain its
current and planned operations through at least 1999. However, the Company's
future capital needs will be dependent upon many factors, including progress in
its research and development activities, the magnitude and scope of these
activities, progress with preclinical and clinical trials, the cost of
preparing, filing, prosecuting, maintaining and enforcing patent claims and
other intellectual property rights, competing technological and market
developments, changes in or terminations of existing collaborative arrangements
and license arrangements, the establishment of additional collaborative and
license arrangements, and the cost of manufacturing scale-up and development of
marketing activities, if undertaken by the Company. If Amgen terminates its
agreement to develop NPS R-568 or other calcimimetic compounds in the Amgen
Territory, the Company may not have the resources necessary to complete the
development and commercialization of NPS R-568 in the Amgen Territory.
 
    Depending on the factors described above, NPS may need to raise substantial
additional funds to support its long-term product development and
commercialization programs. The Company intends to seek additional funding
through corporate collaborations and license agreements. There can be no
assurance the Company will be able to negotiate such agreements in the future on
acceptable terms, or at all. The Company may also seek additional funding
through public or private financings. If additional funds are raised by issuing
equity securities, further dilution to stockholders will result. If adequate
funds are not available, the Company may be required to delay, reduce the scope
of or eliminate one or more of its research and development programs or to
obtain funds through arrangements with collaborative partners or others that may
require the Company to relinquish rights to certain of its technologies, product
candidates or products that the Company may otherwise seek to develop or
commercialize on its own, any one of which could have a material adverse effect
on the Company's operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    LACK OF MARKETING CAPABILITIES.  The Licensees currently have marketing and
distribution rights with respect to products under development for the treatment
of HPT and osteoporosis; however, such commercialization rights may revert to
NPS, under certain circumstances, including upon termination of any of the
related agreements. NPS may retain commercialization rights to other products
developed in the future. The Company currently lacks sales, marketing and
distribution capability. In order to market any of its products directly, the
Company would have to develop a marketing and sales force with technical
expertise and with supporting distribution capability. There can be no assurance
that the Company will be able to establish in-house sales and distribution
capabilities or relationships with third parties, or that it will be successful
in gaining market acceptance for its products.
 
                                       22
<PAGE>
    Outside the United States, the Company's ability to market a product is
contingent upon receiving marketing authorization from the appropriate foreign
regulatory authorities. The requirements governing the conduct of clinical
trials, marketing authorization, pricing and reimbursement vary widely from
country to country. This foreign regulatory approval process includes all of the
risks associated with FDA approval set forth above.
 
    HEALTH CARE LEGISLATION/UNCERTAINTY OF THIRD-PARTY REIMBURSEMENT.  There is
significant national concern today about the availability and rising cost of
health care in the United States. It is anticipated that new federal and/or
state legislation will be passed and regulations adopted to attempt to provide
broader and better health care and to manage and contain its cost. While NPS
cannot predict whether any such legislative or regulatory proposals will be
adopted or the effect such proposals may have on its business, the pendency of
such proposals could have a material adverse effect on the Company's ability to
raise capital, and the adoption of such proposals could have a material adverse
effect on the Company in general.
 
    In both domestic and foreign markets, sales of the Company's product
candidates will depend in part on the availability of reimbursement from
third-party payors such as government health administration authorities, private
health insurers and other organizations. Under current guidelines, Medicare does
not reimburse patients for self-administered drugs. Such policy may adversely
affect the market for products designed to treat patients with age-related
disorders, such as HPT and osteoporosis. In addition, third-party payors are
increasingly challenging the price and cost-effectiveness of medical products
and services. Significant uncertainty exists as to the reimbursement status of
newly approved health care products. There can be no assurance that the
Company's product candidates will be considered cost-effective or that adequate
third-party reimbursement will be available to enable NPS to maintain price
levels sufficient to realize an appropriate return on its investment in product
development. Failure to achieve sufficient price levels for its drugs could
adversely affect the Company's business. Legislation and regulations affecting
the pricing of pharmaceuticals may change before any of the Company's product
candidates are approved for marketing. Adoption of such legislation or
regulations could further limit reimbursement for medical products and services.
Furthermore, the Company's ability to commercialize its potential product
portfolio may be adversely affected to the extent that such legislation has a
material adverse effect on the business, financial condition and profitability
of other companies that are current or future collaborators for certain of the
Company's product candidates.
 
    DEPENDENCE ON KEY PERSONNEL; ABILITY TO MANAGE GROWTH.  The Company is
highly dependent on the principal members of its scientific and management
staff. Loss of any of these persons could adversely affect the Company's
business. The Company does not have employment contracts. The Company's future
success will also depend in large part upon its continued ability to attract and
retain other highly qualified scientific and management personnel. The Company
faces competition for personnel from other companies, academic institutions,
government entities and other organizations. There can be no assurance that NPS
will be successful in hiring or retaining personnel. In addition, the Company's
anticipated growth and expansion into areas and activities requiring additional
expertise, such as clinical trials, government approvals, production and
marketing and general pharmaceutical company management are expected to place
increased demands on the Company's resources. These demands are expected to
require the addition of new management, research and development and
administrative personnel, and the development of additional expertise by
existing management personnel. The failure to acquire such services or to
develop such expertise could materially adversely affect prospects for the
Company's success. Certain of these anticipated future needs are expected to be
met through the agreements with the Licensees and potential additional corporate
collaborations, but there can be no assurance that any services provided by the
Licensees or other potential corporate collaborators will be sufficient to meet
the Company's personnel or management needs.
 
    RISK OF PRODUCT LIABILITY.  The testing, marketing and sale of human
therapeutic products entail significant risks. If the Company succeeds in
developing products under its product development programs,
 
                                       23
<PAGE>
use of such products in clinical trials and the sale of such products following
regulatory approval may expose the Company to liability claims allegedly
resulting from use of such products. These claims might be made directly by
consumers or others. NPS has obtained limited product liability insurance
coverage for its human clinical trials. There can be no assurance that NPS will
be able to maintain such insurance or obtain similar insurance for any of its
future clinical trials or that coverage will be in sufficient amount to protect
against damages for liability that could have a material adverse effect on NPS.
There can also be no assurance that NPS will be able to obtain or maintain
product liability insurance in the future on acceptable terms or in sufficient
amounts to protect the Company against damages for liability that could have a
material adverse effect on the Company. The agreements with the Licensees each
provide for certain indemnification against such claims, but there can be no
assurance that any claim arising from products sold by a collaborative partner
or licensee would not also include claims directly against NPS or that any such
claim would be indemnifiable under such agreement.
 
    USE OF HAZARDOUS MATERIALS.  The Company's research and development
activities involve the controlled use of hazardous materials, radioactive
compounds and other chemicals. The Company is required to comply with complex
local, state and federal regulations involving the use, storage and handling of
these materials and may incur certain costs in complying therewith. Although the
Company believes that its safety procedures for handling and disposing of such
materials comply with the standards prescribed by local, state and federal
regulations, the possibility of unintended non-compliance with such regulations
or the risk of accidental contamination or injury from these materials cannot be
completely eliminated. In the event of such an accident, the Company could be
held liable for any damages that result, and any such liability could exceed the
resources of the Company. The Company may incur substantial costs to comply with
environmental regulations.
 
    The Company contracts with third parties to remove biohazardous waste
generated by the Company. The disposal of such waste, third-party waste disposal
companies contracted by the Company, and their disposal sites are regulated by
the Environmental Protection Agency ("EPA"). The EPA has initiated cleanup of a
site where a waste disposal firm contracted by the Company disposed of certain
waste generated by the Company. The Company has not accrued any liability with
respect to this matter. Although the Company was a small contributor to the site
and the Company believes that there are a number of other financially
responsible contributors, there can be no assurance that the Company will not be
held liable for all or a portion of the cleanup cost or any other costs or
damages associated with this disposal site.
 
    VOLATILE STOCK PRICE.  The market price of the shares of Common Stock, like
that of the common stock of many other biotechnology and biopharmaceutical
companies, has been and is likely to continue to be highly volatile. Factors
such as fluctuations in the Company's operating results, announcements of
technological innovations or new commercial products by the Company or its
competitors, progress with clinical trials, governmental regulation, changes in
reimbursement policies, developments in patent or other proprietary rights,
developments in the Company's relationships with current or future collaborative
partners, public concern as to the safety and efficacy of drugs developed by the
Company and its competitors, and general market conditions for biotechnology or
pharmaceutical stocks could have a significant adverse effect on the future
price of the Common Stock.
 
    ANTITAKEOVER EFFECTS OF SHAREHOLDER RIGHTS PLAN AND CERTAIN CHARTER AND
BYLAW PROVISIONS.  Certain provisions of the Company's Certificate of
Incorporation and Bylaws and Section 203 of the Delaware General Corporation Law
could also discourage potential acquisition proposals and could delay or prevent
a change in control of the Company. Such provisions could diminish the
opportunities for a stockholder to participate in tender offers, including
tender offers at a price above the then current market value of the Common
Stock. Such provisions may also inhibit fluctuations in the market price of the
Common Stock that could result from takeover attempts. In addition, the Board of
Directors, without further stockholder approval, may issue Preferred Stock that
could have the effect of delaying or preventing a change in
 
                                       24
<PAGE>
control of the Company as well as adversely affecting the voting power of the
holders of Common Stock, including the loss of voting control to others. In
addition, the Board of Directors has adopted a Rights Agreement (commonly known
as a "poison pill") which may have the effect of delaying or preventing a change
in control.
 
    ABSENCE OF DIVIDENDS.  The Company has never paid any cash dividends and
does not anticipate paying cash dividends in the foreseeable future.
 
ITEM 2   PROPERTIES.
 
    NPS currently occupies approximately 45,000 square feet of leased
laboratory, support and administrative space in the University of Utah Research
Park. The Company pays approximately $700,000 annually under its facilities
lease. The lease on these facilities expires in September 1999. The Company
anticipates that it will need to acquire additional space in order to meet its
needs over the next three years. The Company believes that it will be able to
acquire additional space on commercially reasonable terms.
 
ITEM 3   LEGAL PROCEEDINGS.
 
    The Company is not a party to any material legal proceedings.
 
ITEM 4   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
    No matter was submitted to the stockholders during the fourth quarter of
1996.

ITEM 7   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
       OF OPERATIONS.
 
    The following discussion of the results of operations and financial
condition of NPS should be read in conjunction with the Financial Statements and
Notes thereto included elsewhere in this report.
 
                                       28
<PAGE>
OVERVIEW
 
    Since its inception in 1986, NPS has devoted substantially all of its
resources to its research and development programs. To date, the Company has not
completed development of any pharmaceutical products for sale and has incurred
substantial losses. NPS has incurred cumulative losses through December 31, 1996
of $14.4 million, net of cumulative revenues from collaborative research and
license agreements of $42.7 million. The Company expects to incur significant
operating losses over at least the next several years as the Company continues
and expands its research and development and preclinical and clinical testing
activities. Substantially all of the Company's revenues are derived from license
fees, milestone payments and research and development support payments from its
Licensees and these revenues fluctuate from quarter to quarter. Accordingly, the
Company expects that income or loss will fluctuate from quarter to quarter, that
such fluctuations may be substantial, and that results from prior quarters may
not be indicative of future operating results. The Company's ability to achieve
profitability depends in part on its ability, alone and/or with others and the
efforts of its Licensees, to complete development of its products, to obtain
required regulatory approvals and to manufacture and market such products, of
which matters there can be no assurance.
 
RESULTS OF OPERATIONS
 
YEARS ENDED DECEMBER 31, 1994, 1995 AND 1996
 
    Substantially all of the Company's revenues of $3.9 million, $9.6 million
and $20.3 million in 1994, 1995 and 1996, respectively, were derived from
research and license agreements. The Company recognized $3.6 million in 1994,
$3.4 million in 1995 and $5.7 million in 1996 under the terms of the SmithKline
Agreement, $6.0 million in 1995 and $4.0 million in 1996 under the terms of the
Kirin Agreement and $10.6 million in 1996 under the terms of the Amgen
Agreement. These revenues were derived from a combination of one-time license
fees, milestone payments and research and development support payments and are
not indicative of future revenue under these agreements. See "Liquidity and
Capital Resources" below for further discussion of payments that may be received
by the Company in the future under these agreements.
 
    Research and development expenses increased from $7.8 million in 1994 to
$8.7 million in 1995 and to $11.0 million in 1996. The increases in research and
development expenses were principally due to the conduct of increasingly
expensive clinical trials for NPS R-568 in 1994, 1995 and early 1996,
preclinical development of NPS 1506 in 1996 and the hiring of additional
personnel. Research and development expenses are expected to increase
significantly in the future as NPS conducts discovery, preclinical development
and clinical trials for non-licensed product candidates, sponsors research or
obtains licenses for technology from academic or research institutions and hires
more research and development personnel.
 
    General and administrative expenses increased from $3.1 million in 1994 to
$4.0 million in 1995 and to $5.5 million in 1996. The increase in 1995 was
primarily due to costs incurred for advisory services in connection with the
consummation of the Amgen and Kirin agreements, and the increased costs
associated with operating a public company for a full year. The increase in 1996
was primarily due to hiring of additional personnel in the areas of business
development, investor relations and legal affairs and costs associated with a
follow-on offering of the Company's stock which was completed in May 1996. The
Company expects that general and administrative expenses will continue to
increase in the future as more personnel and facilities are needed to support
research and development activities.
 
    Interest income increased from $398,000 in 1994 and $480,000 in 1995 to $2.7
million in 1996 primarily due to higher average cash balances resulting from the
net proceeds of the follow-on offering of stock in May 1996. The Company
anticipates that interest income will decrease in the future as the Company's
cash is utilized for operations.

    Income tax expense of $500,000 in 1995 and $200,000 in 1996 resulted from a
10% Japanese tax withheld on the license fee and milestone payment by Kirin.
Future license, milestone and royalty payments from Kirin will be subject to the
same 10% tax. In addition, U.S. alternative minimum tax of $150,000 was incurred
on net income in 1996.
 
    As of December 31, 1996, the Company had a federal income tax net operating
loss carryforward of approximately $11.0 million and a federal income tax
research credit carryforward of approximately $1.2 million. The Company's
ability to utilize these operating loss and research credit carryforwards
against future taxable income will be subject to annual limitations in future
periods pursuant to the "change in ownership rules" under Section 382 of the
Internal Revenue Code of 1986, as amended. See Note 7 of Notes to Financial
Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has financed its operations since inception primarily through
collaborative research and license agreements and the private and public
placement of equity securities. As of December 31, 1996, the Company had
recognized approximately $42.7 million of cumulative revenues from research and
license agreements and approximately $84.3 million in consideration for the sale
of equity securities for cash and services. The Company's principal sources of
liquidity are its cash and cash equivalents which totaled approximately $69.0
million at December 31, 1996.
 
    The Company receives quarterly payments under its agreements with Kirin and
SmithKline Beecham to support the Company's research efforts in HPT and
osteoporosis, respectively. The Kirin payments are $500,000 per quarter through
June 30, 1997 and $250,000 per quarter thereafter through the remaining three
years of the research term of the Kirin Agreement. The scheduled expiration date
of the SmithKline Beecham agreement is October 31, 1997 and NPS expects to
receive approximately $475,000 per quarter in 1997 through that date from
SmithKline Beecham. Amgen will reimburse the Company up to $400,000 per year for
a period not to exceed five years for costs incurred by the Company for
designation of NPS personnel to be available to participate in the development
of a compound for primary HPT in the Amgen Territory, with such participation
occurring under the direction of Amgen.
 
    The Company could receive additional payments of up to $51.0 million in the
aggregate from Amgen, Kirin and SmithKline Beecham upon the accomplishment of
specified research and/or development milestones under the respective
agreements. NPS does not control the subject matter, timing or resources applied
by its Licensees under their respective development programs. Thus, the
Company's potential receipt of milestone payments from these Licensees is
largely beyond the control of NPS. Progress under these agreements is subject to
risk and each of these agreements may be terminated before the scheduled
expiration date by the respective Licensee. Therefore, no assurance can be given
that any future milestone or research or development support payments will be
received thereunder.
 
    The Company has entered into certain sponsored research and license
agreements which obligate the Company to make research support payments to
academic or research institutions. Additional payments may be required upon the
accomplishment of research milestones by the institutions or as license fees or
royalties to maintain the licenses. As of December 31, 1996, the Company had a
total commitment of approximately $1.1 million for future research support
payments. The Company expects to enter into additional sponsored research and
license agreements in the future.
 
    As of December 31, 1996, the Company's net investment in leasehold
improvements, equipment and furnishings was approximately $2.2 million. The
Company has financed a portion of such expenditures through capital leases and
long-term debt with a total principal obligation of approximately $1.5 million
as of December 31, 1996. Additional equipment and facilities will be needed as
the Company increases its research and development activities, a portion of
which may be financed with debt. Equipment and leasehold improvements subject to
the capital leases and the long-term debt have been pledged in support of such
obligations.
 
                                       30

    The Company anticipates that its existing capital resources, including
interest earned thereon and expected research development support payments from
its Licensees will be sufficient to enable it to maintain its current and
planned operations through at least 1999. However, actual needs are dependent on
numerous factors, including the progress of the Company's research and
development programs, the magnitude and scope of these activities, progress with
preclinical and clinical trials, the cost of preparing, filing, prosecuting,
maintaining and enforcing patent claims and other intellectual property rights,
competing technological and market developments, changes in or terminations of
existing research and license arrangements, the establishment of additional
license arrangements and the cost of manufacturing scale-up and development of
marketing activities, if undertaken by the Company. Substantial expenditures
will be required to conduct preclinical studies and clinical trials, manufacture
or have manufactured and market any proprietary products of NPS which may be
derived from current research and development efforts and perform research and
development activities in additional areas. In addition, if Amgen terminates its
agreement, the Company may not have sufficient capital to complete the
development and commercialization of a drug for HPT in Amgen Territory.
 
    NPS may need to raise substantial additional funds to support its long-term
product development and commercialization programs. The Company intends to seek
additional funding through collaborations and licensing agreements and the
Company may seek additional funding through public or private financing. There
can be no assurance that additional financing will be available on acceptable
terms, if at all. If adequate funds are not available, the Company may be
required to delay, reduce the scope of or eliminate one or more of its research
and development programs or to obtain funds through arrangements with licensees
or others that may require the Company to relinquish rights to certain of its
technologies, product candidates or products that the Company may otherwise seek
to develop or commercialize on its own.

The Board of Directors and Stockholders
 
NPS Pharmaceuticals, Inc.:
 
    We have audited the accompanying balance sheets of NPS Pharmaceuticals, Inc.
(a development stage enterprise) as of December 31, 1995 and 1996, and the
related statements of operations, stockholders' equity, and cash flows for each
of the years in the three-year period ended December 31, 1996, and for the
period from October 22, 1986 (inception) to December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of NPS Pharmaceuticals, Inc. (a
development stage enterprise) as of December 31, 1995 and 1996, and the results
of its operations and its cash flows for each of the years in the three-year
period ended December 31, 1996, and for the period from October 22, 1986
(inception) to December 31, 1996, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                       DECEMBER 31, 1994, 1995, AND 1996
 
(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    NPS Pharmaceuticals, Inc. (the "Company"), a development stage enterprise,
is engaged in the discovery and development of orally-active, small molecule
drugs that target selected biological targets, including cell surface receptors
and ion channels. Since inception, the Company's principal activities have been
performing research and development, raising capital, and establishing research
and license agreements. The following significant accounting policies are
followed by the Company in preparing its financial statements:
 
    (a) CASH EQUIVALENTS
 
        The Company considers all highly liquid investments with original
    maturities of three months or less to be cash equivalents. Cash equivalents
    consist of commercial paper, money market funds, and debt securities of
    $5,731,206, $5,120,124 and $67,517,875 at December 31, 1994, 1995, and 1996,
    respectively. At December 31, 1994, 1995, and 1996, the book value of cash
    equivalents approximates fair value.
 
    (b) REVENUE RECOGNITION
 
        The Company recognizes revenue from its research agreements as related
    research costs are incurred and from its license fees and milestone payments
    as earned. Cash received in advance of the performance of the related
    research is recorded as deferred income.
 
    (c) PLANT AND EQUIPMENT
 
        Plant and equipment are stated at cost. Equipment under capital lease is
    stated at the lower of the present value of minimum lease payments at the
    beginning of the lease term or fair value of the equipment at the inception
    of the lease.
 
        Depreciation and amortization of equipment (including equipment held
    under capital lease) are calculated on the straight-line method over their
    estimated useful lives of five years. Leasehold improvements are amortized
    using the straight-line method over the shorter of the life of the asset or
    remainder of the lease term. Amortization of assets held under capital lease
    is included with depreciation and amortization expense.
 
    (d) INCOME (LOSS) PER COMMON AND COMMON-EQUIVALENT SHARE
 
        Income (loss) per common and common-equivalent share have been computed
    based on the weighted average number of shares outstanding during the year,
    after giving effect, if necessary, to the assumption that all dilutive stock
    options were exercised at the beginning of the year or date of grant with
    the proceeds therefrom being used to acquire treasury shares. For periods
    prior to May 26, 1994, the date of the Company's initial public offering,
    upon which all outstanding shares of preferred stock were converted to
    shares of common stock, the loss presented is pro forma after giving
    retroactive effect to the conversion of Series C, D, and E preferred stock
    and the inclusion of common stock options issued for consideration below the
    initial public offering price during the twelve-month period prior to the
    date of the initial filing of the Registration Statement, even when
    antidilutive, pursuant to Securities and Exchange Commission Staff
    Accounting Bulletin No. 83, using the treasury-stock method.

                        (A DEVELOPMENT STAGE ENTERPRISE)
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (e) INCOME TAXES
 
        The Company accounts for income taxes using the asset and liability
    method. Under the asset and liability method, deferred tax assets and
    liabilities are recognized for the future tax consequences attributable to
    differences between the financial statement carrying amounts of existing
    assets and liabilities and their respective tax bases, operating loss, and
    tax credit carryforwards. Deferred tax assets and liabilities are measured
    using enacted tax rates expected to apply to taxable income in the years in
    which those temporary differences are expected to be recovered or settled.
    The effect on deferred tax assets and liabilities of a change in tax rates
    is recognized in income in the period that includes the enactment date.
 
    (f) STOCK-BASED COMPENSATION
 
        Effective January 1, 1996, the Company adopted the footnote disclosure
    provisions of Statement of Financial Accounting Standards (SFAS) No. 123,
    ACCOUNTING FOR STOCK-BASED COMPENSATION. SFAS No. 123 encourages entities to
    adopt a fair-value based method of accounting for stock options or similar
    equity instruments. However, it also allows an entity to continue measuring
    compensation cost for stock-based compensation using the intrinsic-value
    method of accounting prescribed by Accounting Principles Board (APB) Opinion
    No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES (APB 25). The Company has
    elected to continue to apply the provisions of APB 25 and provide pro forma
    footnote disclosures required by SFAS No. 123.
 
    (g) USE OF ESTIMATES
 
        Management of the Company has made estimates and assumptions relating to
    reporting of assets and liabilities and the disclosure of contingent assets
    and liabilities to prepare these financial statements in conformity with
    generally accepted accounting principles. Actual results could differ from
    those estimates.
 
    (h) RECLASSIFICATIONS
 
        Certain amounts in 1994 and 1995 have been reclassified to conform with
    the 1996 presentation.
 
(2) COLLABORATIVE RESEARCH AND LICENSE AGREEMENTS
 
    The Company is pursuing product development both on an independent basis and
in collaboration with others. Following is a description of significant current
collaborations and license agreements:
 
    (a) AMGEN INC.
 
        In March 1996 (effective as of December 1995), the Company entered into
    a development and license agreement with Amgen under which Amgen assumed
    full responsibility and control to develop and commercialize NPS R-568 and
    other compounds for the treatment of hyperparathyroidism and indications
    other than osteoporosis. Amgen agreed to pay to the Company a $10.0 million
    nonrefundable license fee, potential additional development milestone
    payments totaling $26.0 million, up to $400,000 per year for development
    support under the direction of Amgen and royalties on any future product
    sales. Amgen also agreed to purchase one million shares of the Company's
    common stock for

(2) COLLABORATIVE RESEARCH AND LICENSE AGREEMENTS (CONTINUED)
    $7.5 million. Amgen is required to pay all costs of developing and
    commercializing products. Amgen received exclusive worldwide rights
    (excluding Japan, China, Korea, and Taiwan).
 
    (b) KIRIN BREWERY COMPANY, LIMITED
 
        Effective June 30, 1995, NPS entered into a five year agreement with
    Kirin for exclusive rights to develop and commercialize NPS R-568 in Japan,
    China, Korea, and Taiwan. Kirin paid to NPS a $5.0 million license fee and
    has agreed to pay up to $7.0 million in research support, potential
    additional milestone payments totaling $13.0 million, and royalties on
    product sales. The Kirin research support payments are $500,000 per quarter
    through June 1997 and $250,000 per quarter over the remaining three years.
    Both parties will participate in a collaborative research program around
    NPS's parathyroid calcium receptor technology.
 
        The Company recognized the $5.0 million nonrefundable license fee in
    1995. The Company recognized $1.0 million and $2.0 million in research
    support as revenue in 1995 and 1996, respectively. Additionally, the Company
    recognized as revenue a $2.0 million milestone payment related to this
    agreement during 1996.
 
    (c) SMITHKLINE BEECHAM CORPORATION
 
        Effective November 1, 1993, the Company entered into an agreement with
    SmithKline Beecham to collaborate on the discovery, development and
    marketing of drugs to treat osteoporosis and other bone metabolism
    disorders, excluding hyperparathyroidism. The agreement establishes a four
    year research collaboration between the parties and may be extended on
    mutual agreement. The Company granted SmithKline Beecham the exclusive
    license to develop and market worldwide compounds described under the
    agreement, subject to the Company's right to co-promote in the United
    States. Once compounds have been selected for development, SmithKline
    Beecham has agreed to conduct and fund all development of such products,

    In connection with these notes payable, the Company granted the financial
institution in 1995 a warrant to purchase 32,542 shares of common stock at $3.69

(5) CAPITAL STOCK
 
    The Company is incorporated under the laws of the State of Delaware with
authorized capital of 5,000,000 shares of preferred stock and 20,000,000 shares
of common stock, all with a par value of $.001. No shares of preferred stock
were issued or outstanding at December 31, 1995 and 1996.
 
    In December 1996, the Board of Directors approved the adoption of a
Shareholders Rights Plan (the "Rights Plan"). The Rights Plan provides for the
distribution of a preferred stock purchase right ("Right") as a dividend for
each outstanding share of the Company's common stock. This Right entitles
stockholders to acquire stock in the Company or in an acquirer of the Company at
a discounted price in the event that a person or group acquires 20 percent or
more of the Company's outstanding voting stock or announces a tender or exchange
offer that would result in ownership of 20 percent or more of the Company's
stock. Each right entitles the registered holder to purchase from the Company
1/100th of a share of Series A Junior Participating Preferred Stock, par value
$0.001 per share at a price of $50.00 per 1/100th of a preferred share, subject
to adjustment. The Rights may only be exercised on the occurrence of certain
events related to a hostile takeover of the Company as described above. The
Rights will expire on December 31, 2001. The Rights may be redeemed by the
Company at $0.01 per right at any time prior to

expiration or the occurrence of an event triggering exercise. At December 31,

(6) STOCK-BASED COMPENSATION PLANS
 
    The Company has three fixed stock option plans: the 1987 Stock Option Plan
(the "1987 Plan"), the 1994 Equity Incentive Plan (the "1994 Plan"), and the
1994 NonEmployee Directors' Stock Option Plan (the "Directors' Plan"). An
aggregate of 3,220,000 shares have been authorized for issuance under the three
plans.
 
    As of December 31, 1996, there are no shares reserved for future grant under
the 1987 Plan, there are 522,913 shares reserved for future grant under the 1994
Plan, and there are 91,000 shares reserved for future grant under the Directors'
Plan. Under the Company's 1994 Plan, the exercise price of options granted is
not less than the fair market value on the date of grant. The number of shares,
terms, and exercise period are determined by the Board of Directors on an
option-by-option basis, and the exercise period does not extend beyond ten years
from the date of the grant.
 
    Under the Directors' Plan, each new director who is not an employee of the
Company is initially granted options to purchase 15,000 shares of common stock.
Additional options for 3,000 shares are granted on December 1 of each year of
service. The exercise price of options granted is the fair market value on the
date of grant.

    The Company accounts for these plans under APB Opinion No. 25, under which
no compensation cost has been recognized. Had compensation cost for these plans
been determined consistent with FASB Statement No. 123, the Company's net income
(loss) and income (loss) per share would have been reduced or increased,
respectively, to the following pro forma amounts:

    Pro forma net income (loss) reflects only options granted in 1995 and 1996.
The effect that calculating compensation cost for stock-based compensation under
SFAS No. 123 has on the pro forma net income (loss) as presented above may not
be representative of the effects on reported net income or losses for future
years.
 
    The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1995 and 1996, respectively: risk free interest
rates of 5.9 percent and 6.2 percent; expected dividend yields of 0 percent;
expected lives of 5 years; and expected volatility of 80 percent.
 
    In 1996, the Company granted options to purchase 20,000 shares of common
stock to nonemployees. These options have been recorded as a general and
administrative expense at their estimated fair value of $130,000, as determined
by SFAS No. 123.
 
    In November and December 1993, the Company issued options to purchase
378,750 and 4,500 shares of common stock, respectively, at an exercise price of
$2.00 and $4.00 per share, respectively, to employees, officers, and directors
of the Company. For financial statement presentation purposes, the Company has

(6) STOCK-BASED COMPENSATION PLANS (CONTINUED)
recorded as deferred compensation expense the excess of the deemed value of the
common stock at the date of grant over the exercise price. The compensation
expense was amortized ratably over the three-year vesting period of the options
totaling $766,500 for the three-year period.
 
    The Company also has an Employee Stock Purchase Plan (the "Purchase Plan")
whereby qualified employees are allowed to purchase limited amounts of the
Company's common stock at 85 percent of the current market price on the date of
purchase. The Company has authorized 160,000 shares for purchase by employees.
Employees purchased 39,771 and 18,147 shares under the Purchase Plan in the
years ended December 31, 1995 and 1996, respectively, and 102,082 shares remain
available for future purchase. Because the discount allowed to employees under
the purchase plan approximates the Company's cost to issue equity instruments,
the plan is not deemed to be compensatory and, therefore is excluded from the
pro forma income (loss) shown above.
 
(7) INCOME TAXES
 
    The Company has income tax expense of $500,000 and $350,000 for the years
ended December 31, 1995 and 1996, respectively, consisting of current foreign
taxes and alternative minimum taxes.
 
    Income tax expense differed from the amounts computed by applying the U.S.
federal income tax rate of 34 percent to net income (loss) before income taxes
as a result of the following:

    Subsequently recognized tax benefits relating to the valuation allowance for
deferred tax assets as of December 31, 1996 will be allocated as an income tax
benefit to be reported in the statement of operations.
 
    The valuation allowance for deferred tax assets as of January 1, 1995 was
$6.8 million. The net change in the Company's total valuation allowance for the
years ended December 31, 1995 and 1996, was an increase of $1.4 million and a
decrease of $2.4 million, respectively.
 
    At December 31, 1996, the Company had net operating loss and research credit

    Under the rules of the Tax Reform Act of 1986, the Company has undergone a
greater than 50 percent change of ownership since 1986. Consequently, use of the
Company's net operating loss carryforward and research credit carryforward
against future taxable income in any one year may be limited. The maximum amount
of carryforwards available in a given year is limited to the product of the
Company's fair market value on the date of ownership change and the federal
long-term tax-exempt rate, plus any limited carryforward not utilized in prior
years. Management does not believe that these rules will adversely impact the
Company's ability to utilize the above losses and credit in the aggregate.
 
(8) EMPLOYEE BENEFIT PLAN
 
    In October 1990, the Company adopted a tax-qualified employee savings and
retirement plan (the "401(k) Plan") covering all of the Company's employees.
Pursuant to the 401(k) Plan, employees may elect to reduce their current
compensation by the lesser of 15 percent of eligible compensation or the
prescribed annual limit ($9,500 in 1996) and have the amount of such reduction
contributed to the 401(k) Plan. The 401(k) Plan permits, but does not require,
additional matching contributions to the 401(k) Plan by the Company on behalf of
all participants. The Company has not made any such contributions to date.
