ITEM 1.   BUSINESS

INTRODUCTION

         Anesta is a leader in the development of new pharmaceutical products
for oral transmucosal drug administration using its proprietary oral
transmucosal (OT) system. The OT-system consists of a dissolvable,
non-dissolvable, or device-based drug matrix which is mounted on a handle. The
Company's OT-system provides rapid absorption of certain potent drugs into the
bloodstream, which can produce the onset of the desired therapeutic effect
within five to ten minutes. Anesta's OT-system allows the caregiver or patient
to monitor the onset of action, remove the unit and stop administration of the
drug once the desired therapeutic effect has been achieved. In certain
situations, this allows the caregiver or the patient an element of therapeutic
control not possible with traditional drug delivery products and technologies
such as tablets, capsules or transdermal patches. Prior to the development of
Anesta's OT-system, infusions or injections were generally required to achieve
rapid drug absorption, dose control and titration (dose-to-effect). Anesta's
non-invasive OT-system is more comfortable and convenient for patients,
provides flexibility to caregivers, and has the potential to be more effective
and less costly in a variety of clinical settings.

         The Company's first OT-system product is OT-fentanyl. OT-fentanyl was
first approved as Fentanyl Oralet(R) by the U.S. Food and Drug Administration 
(FDA) and is being marketed by Abbott Laboratories (Abbott) for use in both
children and adults as a surgical premedicant and for sedation/analgesia
(conscious sedation) prior to diagnostic or therapeutic procedures in hospital
settings. Fentanyl, the active ingredient, has been widely used in other dosage
forms for over 30 years. Over the last five years, a fentanyl transdermal patch
drug delivery system has gained acceptance among oncologists, internists and
family practice physicians in treating chronic pain, primarily associated with
cancer. U.S. sales of the fentanyl transdermal patch are estimated to be more
than $150 million in a total cancer pain market of more than $1.2 billion
annually.

         In July 1996, Anesta completed its Phase 3 clinical trial program of a
second OT-fentanyl product, Actiq(TM), to treat breakthrough pain (moderate to
severe transitory pain) associated with cancer in patients already receiving
around-the-clock opioid therapy for their persistent or constant pain. The
Company believes that the ability of Actiq to provide rapid relief from
breakthrough pain (onset of meaningful pain relief in five minutes) will
enhance the patient's ability to more precisely control their own pain and
enhance the patient's overall quality of life. Current breakthrough pain
treatment most commonly includes orally administered morphine tablets or
solutions which usually require 30 minutes or more to provide pain relief. In
November 1996, the Company filed its New Drug Application (NDA) with the FDA
for the use of Actiq for breakthrough cancer pain.

         Anesta also has several other products in clinical development,
targeting applications where the OT-system advantages of rapid onset of action
and patient or caregiver control may provide therapeutic value. Products in
clinical trials include OT-fentanyl for acute pain (Phase 2/3), OT-nicotine for
smoking cessation (late Phase 2) and OT-etomidate for sedation (early Phase 2).
Several drugs are being evaluated preclinically with the OT-system, including
drugs to treat migraine headache and nausea and vomiting.

         Anesta entered into a strategic alliance with Abbott in 1989 under
which Abbott has provided funding to Anesta for the development of Fentanyl
Oralet, Actiq and other applications for OT-fentanyl. Abbott contract
manufactures Fentanyl Oralet and Actiq for Anesta and is marketing the
OT-fentanyl product line in the U.S. Abbott has also agreed to manufacture
Anesta's OT-fentanyl line of products, including Fentanyl Oralet and Actiq for
Anesta's potential international distributors and licensing partners.

BACKGROUND ON DRUG DELIVERY METHODS

         A wide variety of drug delivery systems are available in the market,
although not all drugs can be beneficially delivered by all routes of drug
delivery administration. For certain clinical applications, there are clinical
benefits in providing rapid onset of therapeutic action and the appropriate
drug dosage necessary to achieve the desired effects. Drug delivery should be
convenient, cost-effective and as non-invasive as possible. Existing drug
delivery systems each have limitations in meeting some of these requirements:

         Tablets or capsules. Although orally delivered tablets or capsules may
be convenient and inexpensive, they generally do not provide rapid onset of
action. Also, some drugs do not achieve adequate bioavailability when
administered as a tablet or capsule due to degradation of the drug by the
stomach and liver.

         Infusions and injections. Intravenous (IV) infusions, intramuscular
(IM) and subcutaneous (SC) injections provide rapid uptake and onset of action.
Infusion techniques can titrate potent drugs with very rapid changes in effect.
However, infusions and injections are painful, invasive and sometimes
threatening to the patient. IV infusions and SC and IM injections require
highly trained medical professionals for safe and effective administration.

         Transdermal patches. Transdermal patches, which allow absorption of
drugs through the skin, provide convenience, ease of administration and a more
steady rate of chronic drug delivery. However, the time to achieve therapeutic
blood levels with transdermal patches may be four to ten hours after
administration. In addition, absorption of the drug into the bloodstream may
continue for many hours after removal of the patch. This slower onset of action
and inability to quickly stop absorption are limiting factors of transdermal
patches and present safety concerns in some clinical situations. For example,
patients in acute pain cannot wait several hours to achieve analgesia and such
patients sometimes may need to be hospitalized in order that more invasive
methods (IV, SC, IM) can be administered by skilled health care professionals.

         Nasal/Transnasal Sprays. Nasal sprays are designed to provide rapid
onset of action of drugs or are designed to deliver drugs that are not orally
bioavailable. Nasal sprays can cause irritation in some patients and can be
difficult to administer in variable intranasal conditions. In addition, the
dose of the product cannot be titrated or controlled by the patient over a
period of time.

ANESTA'S PROPRIETARY OT-SYSTEM FOR DRUG DELIVERY

         Anesta's proprietary OT-system is designed to address the medical need
for a convenient, non-invasive, cost-effective drug delivery system that
provides rapid onset of therapeutic action and allows the caregiver or patient
to control drug administration until the desired effect is achieved. The
OT-system consists of a dissolvable, non-dissolvable, or device-based drug
matrix which is mounted on a handle. The drug is released from the matrix in
the mouth, allowing rapid absorption through the oral mucosal tissues and
slower absorption through the gastrointestinal tract. Oral transmucosal drug
delivery achieves rapid absorption of many drugs because the oral mucosa has a
large surface area (100 - 150 cm2), is highly vascularized and is significantly
more permeable than the skin.

         For certain drugs or certain applications, Anesta believes that its
OT-system can provide one or more of the following therapeutic advantages over
traditional methods of drug administration:

         Rapid Onset of Action. The efficacy of many systemic drugs is related
to their blood concentration. In order to achieve a therapeutic effect, a
particular blood concentration must be achieved. The more rapidly that such
blood concentration is reached, the sooner the drug takes effect. The Anesta
OT-system allows many types of drugs to cross the oral mucosa and to be
absorbed rapidly into the bloodstream, thus achieving a therapeutic blood
concentration more rapidly than tablets and capsules or transdermal patches.

         Dose-to-Effect Control. Anesta's OT-system allows the caregiver or
patient to monitor the onset of action, remove the unit and stop administration
of the drug once the desired therapeutic effect has been achieved. This avoids
doses that are higher than necessary to achieve safe and effective therapy, an
important and beneficial element of control. Drugs delivered by tablet and
capsule may be significantly degraded by the stomach and the liver. Thus,
tablets and capsules often contain higher doses of a drug than necessary to
achieve a therapeutic effect, potentially leading to over-medication and
undesirable side effects. Continuous 



                                       3
<PAGE>   4

infusion therapy or more frequent administration of tablets or capsules can
alleviate these dosing problems, but may lead to increased cost, patient
inconvenience and patient noncompliance with prescribed dosing regimens.

         Rapid Termination of Drug Delivery. In certain applications, it is
desirable that drug administration be terminated once the desired effect has
been obtained. For example, if a patient receives a sedative in connection with
a brief outpatient procedure, substantially all of the sedative effect should
be gone before the patient can be discharged. The drug contained in a tablet or
capsule may dissolve and continue to be absorbed into the bloodstream over a
period of hours. Similarly, when a transdermal patch is removed, the drug which
has already made contact with the skin will continue to be absorbed into the
bloodstream for a number of hours or even days. Thus, drug absorption from
tablets, capsules and transdermal patches may continue longer than necessary or
desired. By contrast, once Anesta's OT-system is removed, absorption of the
drug through the oral mucosal tissues into the bloodstream stops almost
immediately.

         Improved Safety. Removing the OT-system limits further absorption of
the drug into the body if a patient has an adverse reaction or has achieved the
desired therapeutic effect. Because the dosage unit can be removed immediately,
the amount of the drug delivered to the patient may be lower than if a tablet,
capsule, transdermal patch or injection had been administered.

         Cost-Effective. Traditionally, when rapid onset of action is critical,
infusions or injections have been required. Infusions and injections require
administration by a skilled caregiver and, in the case of IV or SC
administration, a catheter must be inserted and an administration set-up is
required. In contrast, the OT-system requires simple placement of the dosage
unit in the mouth. Thus, Anesta believes that its OT-system may offer a more
cost-effective means of delivering certain drugs that are now given by infusion
or injection.

         Greater Patient and Caregiver Convenience. The Company's OT-system is
easily administered, comfortable, non-threatening and allows a caregiver or the
patient the ability to titrate drug administration.

ANESTA'S BUSINESS STRATEGY

         Anesta's long-term objective is to apply its proprietary OT-system in
a number of therapeutic areas and to commercialize new pharmaceutical products
using this system. Anesta is pursuing this objective with the following
strategy:

     Proprietary Technology. The Company has sought and will continue to expand
its proprietary position for its OT-system, by pursuing patent protection in
the U.S. and key international markets for its OT-system and for dosage forms
that incorporate such technology.

         Approved Drugs. The Company develops new pharmaceutical products by
applying its OT-system primarily to approved drugs, including both proprietary
and generic drugs, in order to create new dosage forms for applications where
existing methods of drug delivery have therapeutic or clinical limitations.

         Focused Resources. Anesta focuses its resources on research, product
and process development, clinical research, regulatory interactions and filings
and commercial market development and preparation. Anesta works closely with
Abbott in developing Fentanyl Oralet, Actiq and other OT-fentanyl applications
and plans to develop strategic relationships with other pharmaceutical
companies to develop, manufacture, market and distribute Anesta's OT-system
products worldwide.

         The Company believes that this strategy offers a number of potentially
significant benefits. First, by focusing on developing new dosage forms for
approved drugs, Anesta does not bear the cost and risk associated with
discovery and development of new pharmaceutical compounds. Second, by entering
into relationships with strategic partners for costly activities such as
manufacturing, marketing, selling and distribution, Anesta is able to focus its
resources on research, development, regulatory interactions and filings and
commercial market development activities where the Company can add significant
value to its partnerships.

  Fentanyl Oralet (OT-fentanyl) for Premedication

      Fentanyl Oralet is approved by the FDA for use in both adult and
pediatric patients in a hospital setting (i) as a surgical premedication or
(ii) to provide sedation/analgesia (conscious sedation) prior to diagnostic or
therapeutic procedures. The unique design of Fentanyl Oralet provides
physicians with a new method of administering fentanyl in a controllable yet
painless and easy to use dosage form. Patients experience an onset of analgesia
in six to eight minutes and sedation and reduced anxiety in 20 to 30 minutes.

  Actiq (OT-fentanyl) for Breakthrough Pain

      Phase 3 clinical research for Anesta's OT-fentanyl product for
breakthrough pain, Actiq, was completed in July of 1996 and the Actiq NDA was
filed in November of 1996. Anesta believes that Actiq has the potential to
bring about a major advance in pain management for persons suffering moderate
to severe breakthrough pain. Data from the Company's clinical trials in cancer
and other patients show that Actiq provides patients onset of pain relief in
approximately 5 minutes that is predictable, controllable, convenient and safe.

      In recent years there has been a growing awareness that millions of
cancer patients do not receive optimal analgesic therapy for their pain.
Inadequate pain management leads to debilitation, reduced quality of life and
great stress on interpersonal relationships with family, friends and
caregivers. Many clinicians believe that improving a patient's control over
pain also helps in his or her ability to better fight the underlying disease.

      With improved clinician awareness and understanding of the importance of
managing pain as an integral part of overall cancer therapy, there is a desire
to find solutions to one of the most challenging components of cancer pain,
namely breakthrough pain. Breakthrough pain is a transitory flare of moderate
to severe pain 


                                       5
<PAGE>   6

occurring on a background of persistent or constant pain in patients receiving
chronic opioid therapy. Breakthrough pain may be related to a specific activity
or may occur spontaneously and be totally unpredictable. When related to a
specific activity such as walking or eating, it may be termed incident pain.
Various studies have shown that over 50% of all patients with active cancer
experience moderate to severe pain. Over 70% cancer patients experience
moderate to severe pain in the end stage of the disease. Other studies have
shown that 52 to 64% of these patients experience breakthrough pain. These
studies suggest that over 800,000 cancer patients suffer from breakthrough pain
each year in the U.S. alone.

      Clinical practice guidelines suggest the use of a long-acting opioid
analgesic, such as sustained-release morphine or the fentanyl transdermal
patch, in an around-the-clock dosing regimen to treat the persistent or
constant pain component of cancer pain. When the transitory flares of moderate
to severe breakthrough pain occur, patients are instructed to self-medicate
with an analgesic with a relatively faster onset, such as oral morphine tablets
or elixirs.

      Breakthrough pain typically develops rapidly and often reaches maximum
intensity in three minutes. It has a variable duration averaging approximately
30 minutes. These episodes can be excruciatingly painful and may last for one
or two hours. Oral morphine is not optimal to treat breakthrough pain because
it typically requires 30 minutes or more to produce pain relief (analgesia).
This delayed onset of pain relief results in a "pain relief gap" -- the painful
and debilitating wait between onset of breakthrough pain and the beginning of
pain relief.

      One approach to managing breakthrough pain is to increase the dose of the
around-the-clock, long-acting opioid analgesic over several days or weeks until
the patient no longer experiences breakthrough pain. This approach frequently
leads to over medication and an increase in undesirable side effects such as
drowsiness or severe constipation. As patients and their physicians learn from
their experience, they will often seek a balance of drug therapy that meets the
patient's desire for fewer or less severe breakthrough pain episodes offset by
a need to minimize the side effects of higher opioid doses. Often this
compromise leads to an acceptance of one to four episodes of breakthrough pain
every day. As a result, breakthrough pain is a frequent occurrence in the lives
of many cancer patients. Most of these patients have a need for a better
therapy to more effectively treat breakthrough pain.

      The only currently available treatments which adequately match rapid
onset of pain relief to the rapid onset of breakthrough pain are IV or SC
infusions or IM injections of potent opioids, such as morphine. In many
settings, these options are unacceptable because they are invasive,
uncomfortable, inconvenient for patients and caregivers, and can lead to
significantly increased costs.

      The ideal treatment for breakthrough pain would provide very rapid pain
relief in a simple, controllable, safe and patient-friendly manner. Anesta
believes that Actiq meets these criteria as it provides rapid onset of pain
relief (in five minutes) in a dosage form that provides the patient a means of
controlling the dose (dose-to-effect), and that is safe, convenient,
user-friendly and less costly than invasive methods.

      Patients, nurses and physicians have stated that the two most important
factors in treating breakthrough pain are speed of onset and patient control.
Actiq meets these criteria in a drug delivery system that provides rapid onset
of pain relief and is convenient and controllable by the patient. Moreover,
U.S. Government and World Health Organization cancer pain guidelines teach
early and aggressive use of oral or other non-invasive opioid analgesic therapy
to treat patients with moderate to severe pain. The guidelines also teach that
injections and infusions should be avoided if possible and used only as a last
resort. The Company believes Actiq closely fits with these guidelines.

      Anesta's Phase 3 cancer pain clinical program involved 12 studies at 45
U.S. sites. The program was designed to determine the safety and effectiveness
of Actiq as well as to gather practical information such as the proper dosing
recommendations for the product in patients receiving conventional
around-the-clock opioids for chronic pain. Two blinded titration trials were
designed to develop a practical method for patients to achieve optimal relief
from breakthrough pain. Incrementally higher doses were administered until a
dose was found where one unit of Actiq was effective for an average
breakthrough pain episode. Another blinded trial was designed to demonstrate
the efficacy of Actiq compared to placebo for breakthrough pain. Actiq was also
investigated in a small supporting study as the sole source (monotherapy) for
pain control in opioid tolerant patients. Additionally, long-term safety was
assessed in a follow-on study where cancer patients are 


                                       6
<PAGE>   7


allowed to continue with Actiq therapy, if they desire, after completing one of
the other trials. The Company's clinical trials in total enrolled 257 cancer
patients who have received over 41,000 doses of Actiq as of November 1996,
during participation in these trials. Several patients have completed more than
12 months of Actiq therapy with continuing effectiveness in treating their
episodes of breakthrough pain.

      In double-blind dose titration studies, Actiq produced significantly
faster and better pain relief scores than currently used breakthrough pain
medications at 15, 30, and 60 minutes following study drug administration.
Patient assessment, based on global performance ratings which blend efficacy,
side-effects, dosage form and other factors, was also significantly better with
Actiq when compared with baseline breakthrough pain medications. In a pain
assessment trial of postoperative surgical patients, the median time for onset
of meaningful pain relief (analgesia)following administration of Actiq was less
than 5 minutes.

      Ninety-one percent of the patients in the three pivotal studies who were
eligible to continue Actiq therapy chose to enroll in an open-label, long-term
study of Actiq. Mean global performance ratings for Actiq were consistently in
a range indicating very good to excellent pain relief for the duration of
therapy in the long-term study. The main side effects reported during the
cancer pain clinical studies with Actiq were similar in type and prevalence to
those caused by all opioid analgesia products used to treat chronic pain
patients.

      The Actiq dosage form, consisting of a drug matrix attached to a handle,
facilitates absorption of the drug within the mouth and enables the patient to
individually control drug delivery. This helps achieve rapid and effective pain
relief while minimizing side effects in a patient-friendly, non-invasive oral
transmucosal delivery system.

      The proposed treatment plan for using Actiq for breakthrough pain will be
simple and consistent with current practice and published guidelines.
Physicians will prescribe an around-the-clock opioid analgesic for constant
pain, using conventional products like sustained-release morphine tablets or
fentanyl transdermal patches. The patient will be instructed to use an Actiq
instead of oral morphine when the patient feels the onset of breakthrough pain.
As the patient sucks on the Actiq, it dissolves and releases the drug for rapid
absorption through the mucosal tissues providing a fast onset of pain relief. A
recent Actiq clinical study of post-operative patients with acute pain showed
that the onset of meaningful pain relief occurred in under five minutes in over
50% of the patients and within 15 minutes for substantially all patients.
Currently available oral opioid products have a much slower onset of
therapeutic effect.

  Other Products in Development

      Anesta has several OT-system products under clinical development for the
following clinical applications:

      OT-fentanyl for acute pain. OT-fentanyl is also being studied for acute
pain. There are multiple causes of acute pain including surgery, trauma and
conditions such as kidney stones. Acute pain usually requires the rapid onset
of pain relief. Historically, hospitalized patients have received IV or SC
infusions or IM injections in order to receive rapid pain relief. A more recent
enhancement to the IV route of administration of analgesics has been the
development of patient controlled devices with sophisticated microelectronics,
which allow patients to self-administer the IV pain medication when they feel
the need for pain relief. This method of patient controlled analgesia (PCA) has
been shown to improve pain management, at the same time decreasing the total
daily dose of medication used. There are also psychological benefits to the
patients who gain more control over their analgesic therapy.

      PCA therapy is a major improvement for pain management and reduces the
need for skilled caregivers to provide repeat IV or SC infusions or IM
injections. Anesta's OT-system takes the PCA concept one step further. Instead
of relying on invasive and costly IV infusions, OT-fentanyl will provide the
rapid onset of pain relief in a noninvasive and cost-effective delivery system
in a hospital setting.

      Anesta has completed several Phase 2/3 clinical studies in over 300
patients experiencing acute pain after surgery. During the past year, data from
some of these studies have been presented at peer-reviewed scientific meetings.
These early data provide evidence that OT-fentanyl can be clinically effective
for acute pain in a hospital setting.

      OT-nicotine (OTNC) for smoking cessation. Anesta's OT-nicotine product is
in late-stage Phase 2 clinical development. OTNC is a new therapy targeted to
help individuals overcome dependence on tobacco.

      Seven clinical studies with OTNC have been completed. These studies have
evaluated the effects of different dosage strengths, the acceptability of
different taste formulations, and the ability of OTNC to aid smoking cessation
with limited, short-term use and with eight weeks of therapy. Clinical
pharmacokinetic data showing blood levels after different OTNC doses were
presented at the Society for Research on Nicotine and Tobacco annual meeting in
March 1996 and clinical data with short-term use were presented at the American
Society of Addiction Medicine in November 1996. These data demonstrated that
blood concentrations increase in proportion to dose, the desire to smoke
decreases at higher doses, high patient acceptance, and side effects typical of
nicotine.

      Nicotine replacement therapy has become established as a successful aid
to smoking and tobacco cessation programs. Nicotine replacement products that
have been approved include a nicotine gum, several transdermal nicotine patches
and nicotine nasal spray. In February 1996, nicotine gum was approved by the
FDA in the U.S. for over-the-counter sales and distribution and in July 1996,
two nicotine transdermal patches were approved by the FDA for over-the-counter
sales and distribution. A number of other companies are developing other types
of nicotine replacement products, as well as other smoking cessation products,
which, if approved, would compete with OTNC. Smoking cessation experts believe
that increasing the availability and number of nicotine replacement products
will increase their benefits on public health, as no single therapy will be
effective for all smokers desiring to quit. These experts foresee a need for a
broad range of readily available products and therapies to increase the success
rate of smoking cessation programs.

      OTNC provides a combination of pharmacokinetic profile and behavioral
characteristics that are different from the other nicotine replacement products
currently on the market. Some smokers who have used OTNC for up to one week
have commented that the ability to control dosing by repeatedly inserting and
removing the OTNC unit from their mouths has given them a greater ability to
manage their urge to smoke. This element of control is different from that
offered by these other treatment modalities. Anesta believes that this ability
to titrate the dose of nicotine and rapidly deliver adequate doses of nicotine
to the individual may more closely displace the physiologic dependence and
psychological craving effects of cigarettes. These properties of OTNC may be
especially effective in the early stages of smoking cessation and in smoking
relapse prevention.

      OT-etomidate (OTET), an ultra-short acting, non-opioid sedative and
anxiolytic. OTET is beginning Phase 2 clinical studies. This product is
designed to broaden Anesta's product line in providing sedation and reducing
anxiety in situations where the procedure is not painful or where pain is
managed by other methods such as local or regional anesthesia. The active
ingredient in OTET, etomidate, is an approved anesthetic drug when supplied in
an IV dosage form.

      The first two Phase 1 clinical studies confirmed that OTET delivers
dose-related therapeutic blood levels to produce sedation and anxiolysis in 10
to 20 minutes. Sedation and anxiolysis continue for 30 to 40 minutes. Emergence
from sedation to a level indicative of complete recovery occurs 60 to 90
minutes after taking the drug. This profile is very close to the sedation
specifications described as ideal by anesthesiologists for many short
procedures and by experts in dental sedation.

      An additional clinical study has just been completed, where the primary
objective was to evaluate and document the rapid, uneventful recovery of
psychomotor and cognitive function after administration of OTET. Such rapid
recovery is critically important in managed health care environments
emphasizing productivity in health care delivery. The Company is seeking to
establish in its Phase 2 clinical trials that OTET can provide rapid
clear-headed patient recovery and discharge after a procedure is completed. The
Company believes this addresses an important goal in managed care to maximize
the utilization of high cost facilities.

      OT-system products to treat migraine headaches. Anesta is conducting
preclinical research and development of products to treat migraine headaches.
The Company believes that the OT-system has the potential to provide
therapeutic benefit for persons suffering migraine headaches because of the
ability to produce rapid uptake of drug into the bloodstream without the need
for infusions or injections.

      OT-system products to treat nausea and vomiting. Anesta is conducting
preclinical research and development of OT-system products to deliver
anti-emetic drugs. The Company believes that its OT-system can be used to treat
post-surgical nausea and vomiting, emesis induced by chemotherapy, or nausea
and vomiting secondary to conditions such as migraine headache or AIDS.
Currently, anti-emetics are administered orally, rectally, by injection or by
transdermal patches. Unlike oral tablet delivery, Anesta's OT-system would
allow the patient the ability to remove the dosage form from the mouth should
an emetic episode occur during administration of the drug. In addition, oral
transmucosal delivery avoids painful injections yet would provide rapid onset
similar to an injection. Patches typically require hours to reach effective
blood levels, making them less attractive for treating acute episodes of nausea
and vomiting. Anesta believes there is an unmet clinical need for a
non-invasive method which allows patients the ability to control the delivery
of anti-emetic drugs.

RESEARCH AND DEVELOPMENT STRATEGY

      Anesta develops its proprietary OT-system and products both independently
and with the collaboration of the University of Utah and its assignee, the
University of Utah Research Foundation (collectively, the UURF) and Abbott.
Future development projects may involve collaboration with other established
pharmaceutical companies. The Company's primary emphasis is on research,
product and process development, clinical research, regulatory interactions and
filings and commercial market development and preparation. The Company
currently produces its clinical supplies for clinical studies in its own pilot
manufacturing facility and intends to expand manufacturing capabilities to
develop improved manufacturing technologies to support larger clinical research
projects and to demonstrate scale-up capabilities (manufacturing process
development). Since its inception, Anesta has managed most aspects of its
clinical trials and has prepared substantially all U.S. regulatory filings for
its products. In 1996, 1995, and 1994, Anesta's research and development
expenditures were $8,304,000, $5,228,000 and $3,210,000 respectively.

COLLABORATIVE RELATIONSHIPS

      Anesta's commercial strategy is to develop products independently and,
where appropriate, including internationally, in collaboration with established
pharmaceutical companies and institutions. Collaborative partners may provide
financial resources, research and manufacturing capabilities and marketing
infrastructure to aid in the commercialization of Anesta's products in
development and potential future products. Depending on the availability of
financial, marketing and scientific resources, among other factors, the Company
may license its technology or products to others and retain profit sharing,
royalty, manufacturing, co-marketing, co-promotion or similar rights. Any such
arrangements could limit the Company's flexibility in pursuing alternatives for
the commercialization of its products.

  Abbott Laboratories

      In December 1989, Anesta entered into a research and development,
license, supply and distribution agreement with Abbott. Under the agreement, as
amended (the "1989 Agreement"), Anesta granted to Abbott the exclusive right to
make, use and market in the U.S. OT-products resulting from technology owned or
licensed by Anesta consisting of OT-fentanyl or other central nervous
system-acting drugs or intermediates thereof used for pre-medication, sedation,
analgesia, diagnostic procedures, emergency room, post-operative pain, burn
treatment or cancer-related pain management. Abbott's exclusive license
terminates upon the expiration of the last U.S. patent relative to such
licensed technology. Under the 1989 Agreement, Abbott has provided development
funding and milestone payments and Abbott is obligated to pay royalties and
other payments on product sales. In 1995, the Company entered into two new
funding agreements with Abbott under which Abbott agreed to provide to the
Company $1,500,000 in each of 1995 and 1996 to further the development of the
OT-fentanyl product, Actiq, for cancer pain. Through December 31, 1996, Abbott
had paid a total of $9,375,000 with $375,000 due to the Company. An additional
$300,000 is payable from Abbott to Anesta upon approval of the Actiq NDA in the
U.S. Abbott is Anesta's contract manufacturer for the OT-fentanyl product line
and sells such products to Anesta. Anesta resells OT-fentanyl products to
Abbott for marketing in the U.S. under Abbott's trademark Fentanyl Oralet and
Anesta's trademark Actiq.




                                       9
<PAGE>   10



      The 1989 Agreement with Abbott contains provisions regarding the
development, manufacture and commercialization of future products by the
Company. The Company intends to continue to provide information to Abbott
regarding its development programs for new products, and to discuss with Abbott
its possible participation in the commercialization of such products.

      The 1989 Agreement with Abbott can be terminated with respect to a
particular market or indication upon thirty days notice by Abbott if (i) there
exists a material adverse safety concern with respect to a licensed product,
(ii) there exists a material adverse concern regarding the efficacy of a
licensed product, (iii) action by the FDA precludes the continued testing or
commercialization of a licensed product, and such preclusion is more than
temporary in nature, or (iv) a third party patent poses an infringement risk
with respect to the commercialization of a licensed product in the U.S.

      Effective October 12, 1995, the Company entered into an amendment to a
prior agreement between Abbott International (A.I.) and the Company to provide
the Company the right to terminate or cause to become nonexclusive A.I.'s
license rights to OT-fentanyl products in one or more countries in the world
except the U.S. The amendment also eliminated $100,000 of the $450,000 unearned
advance royalty obligation, which amount was recognized as royalty revenue
during the year ended December 31, 1995.

  University of Utah Research Foundation

      In 1985, the Company obtained an exclusive worldwide license, including
the right to sublicense, from the UURF to all of the UURF's technology
developed or to be developed by Dr. Theodore H. Stanley, Chairman of the Board
of the Company, and others during employment at the University of Utah in (i)
the field of anesthetic and other drug delivery systems incorporating a matrix
to deliver compounds to the central nervous system via the mucosal tissues of
the mouth, pharynx and esophagus, (ii) drug-based immobilization systems for
human and veterinary applications and (iii) transdermal drug delivery systems.
The Company is obligated to pay certain royalties to the UURF subject to
certain minimum royalty payments. In addition, Anesta is obligated to pay to
the UURF a higher percentage of the royalties it receives in the event Anesta
sublicenses the licensed technology without any improvement or added value. The
Company also has an exclusive option with UURF to acquire an exclusive
worldwide license to similar technology and intellectual property that may be
conceived, invented or reduced to practice at the University of Utah after the
date of its license grant. Anesta has exercised such option as to all
technology covered by its patents and pending patent applications. The UURF
exclusive worldwide license terminates as to each country upon the expiration
of the last patent in such country relating to the licensed technology.

MANUFACTURING

      Anesta has a pilot manufacturing facility capable of producing limited
quantities of its proprietary OT-products for formulation and methods
development, animal studies and clinical studies. Anesta has licensed
manufacturing rights to certain of its products to Abbott subject to the right
of Anesta to manufacture such products under certain circumstances.

      The Company is in the process of developing manufacturing processes and
the capacity to produce sufficient amounts of OT-products to conduct larger
scale clinical studies. This manufacturing process is designed to produce large
volumes and reduce the unit cost of producing OT-products. The Company will
also have to adhere to cGMP regulations enforced by the FDA's facilities
inspection program, as well as requirements imposed by the Drug Enforcement
Agency (DEA).




                                      10
<PAGE>   11



COMPETITION

      Fentanyl Oralet, Actiq and other Company products will compete with other
drugs and drug delivery systems. Anesta believes that its products will compete
on the basis of quality, efficacy, cost, convenience, safety, patient
compliance and patient preference.

      The new products being developed by the Company will compete with drugs
marketed in both traditional and advanced forms of drug delivery. New drugs or
further developments in alternative drug delivery methods may provide greater
therapeutic benefits for a specific drug or indication, or may offer comparable
performance at lower cost, than those offered by the Company's proprietary
OT-system.

      Competition in the pharmaceutical industry is intense. Many
pharmaceutical companies, biotechnology companies, public and private
universities and research organizations actively engage in research and
development of pharmaceutical products and drug delivery systems. Many of the
Company's existing or potential competitors have substantially greater
financial, technical and human resources than the Company and may be better
equipped to develop, manufacture and market products. In addition, many of
these companies may develop and introduce products and processes competitive
with or superior to those of the Company. The Company's product development
programs are subject to significant competition from companies utilizing
alternative development strategies.

PATENTS, PROPRIETARY RIGHTS AND LICENSES

      The basic technology underlying the Company's proprietary OT-system was
invented by Dr. Stanley and Brian Hague, both employees of the Company, while
employed at the University of Utah. Anesta is the exclusive worldwide licensee
of such technology under patents held by the UURF through a license granted in
1985 which remains in effect for the life of all applicable patents. The U.S.
patents expire on various dates ranging from 2004 to 2010 and the foreign
patents expire on various dates ranging from 2003 to 2010. Anesta maintains, at
its expense, all U.S. patent rights with respect to the licensed technology and
files and prosecutes the relevant patent applications in the U.S. and foreign
countries. The OT-system technology underlying Anesta's exclusive license is
covered by 10 issued U.S. patents, 76 issued foreign patents, 22 pending U.S.
patent applications and 31 pending foreign patent applications. The Company
also relies upon trade secrets, know-how, continuing technological innovations
and licensing opportunities to develop and maintain its competitive position.
The Company plans to prosecute and defend its technology and the patents and
patent applications being licensed from the UURF.

      Substantially all of the patents issued and pending which underlie the
licensed technology relate to different embodiments of OT technology and other
transmucosal therapeutic technologies. The Company believes that its
proprietary technologies, which are protected by issued and pending U.S.
patents, may provide it a significant competitive advantage. The Company's
agreement with Abbott provides that Anesta owns all rights to inventions made
by Anesta personnel and owns joint rights to inventions made by Anesta and
Abbott jointly which underlie the licensed technology.

      The Company's policy is to protect its technology by, among other things,
filing, or requiring the UURF to file, patent applications for technology that
it considers important to the development of its business. Anesta intends to
file additional patent applications, when appropriate, relating to its
technology, improvements to its technology and to specific products it
develops.

      It is the Company's policy to require its employees, consultants, outside
scientific collaborators and sponsored researchers and other advisors to
execute confidentiality agreements upon the commencement of employment or
consulting relationships with the Company. These agreements provide that all
confidential information developed or made known to the individual during the
course of the individual's relationship with the Company is to be kept
confidential and not disclosed to third parties except in specific
circumstances. In the case of employees, the agreements provide that all
inventions conceived by the individual in the course of his or her employment
shall be the exclusive property of the Company.

GOVERNMENT REGULATION

      The Company's activities and products are subject to significant
regulation by a number of governmental entities, especially the FDA and DEA in
the U.S. and by comparable authorities in other countries. These entities
regulate, among other things, research and development activities and the
testing, manufacture, safety, effectiveness, labeling, storage, record keeping,
approval, advertising, promotion, distribution and sale of the Company's
products. Product development and approval within this regulatory framework
takes a number of years and involves the expenditure of substantial resources.
Many products that appear promising initially ultimately do not reach the
market because they are found to be unsafe (perhaps too toxic) or lack
effectiveness, as demonstrated by testing required by government regulation
during the development process.

      The activities required before a pharmaceutical product may be marketed
in the U.S. primarily begin with preclinical testing. Preclinical tests include
extensive laboratory evaluation of product chemistry and other end points and
animal studies to assess the potential safety and efficacy of the product as
formulated. Almost all preclinical studies pertinent to drug approval are
regulated by the FDA under a series of regulations called the Good Laboratory
Practice (GLP) regulations. Violations of these regulations can, in some cases,
lead to invalidation of the studies, requiring such studies to be replicated.

      The entire body of preclinical development work necessary to administer
investigational drugs to volunteers or patients is summarized in an
Investigational New Drug (IND) submission to the FDA. FDA regulations provide
that clinical trials may begin 30 days following the submission and receipt of
an IND, unless the FDA advises otherwise or requests additional information,
clarification or additional time to review the IND submission; it is generally
considered good practice to obtain affirmative FDA acquiescence before
commencing trials. There is no assurance that the submission of an IND will
eventually allow a company to commence clinical trials. Once trials have
commenced, the FDA may stop the trials, or particular types or parts of trials,
by placing a "clinical hold" on such trials because of concerns about, for
example, safety of the product being tested or the adequacy of the trial
design. Such holds can cause substantial delay and in some cases may require
abandonment of a product.

      Clinical testing involves the administration of a drug to healthy
volunteers or to patients under the careful supervision of a qualified
principal investigator, usually a physician, pursuant to an FDA-reviewed
protocol. Clinical tests pertinent to an IND are usually conducted in the
following sequential phases, although the phases may overlap. Phase I trials
generally involve administration of a drug product to a small number of persons
to determine aspects of safety, tolerance, pharmacokinetic characteristics, and
possible early data on effectiveness. Phase II trials generally involve
administration of a product to a limited number of patients with a particular
disease to determine dosage, efficacy and safety. Phase III trials generally
examine the clinical efficacy and safety in an expanded patient population at
multiple clinical sites. Pivotal Phase III trials are trials designed to
demonstrate definitive efficacy. At least one such trial is required for FDA
approval to market a drug. Each clinical study is conducted under the auspices
of an independent Institutional Review Board (IRB) at every institution at
which the study will be conducted. An IRB will consider, among other things,
ethical factors, the safety of human subjects and the possible liability of the
institution.

      The regulatory process required to be completed by the FDA before a new
drug delivery system may be marketed in the U.S. depends significantly on
whether the drug (which will be delivered by the drug delivery system in
question) has existing approval for use and in what dosage forms. If the drug
is a new chemical entity that has not been approved, then the process includes
(i) preclinical laboratory and animal tests, (ii) an IND application which has
become effective, (iii) adequate and well-controlled human clinical trials to
establish the safety and efficacy of the drug in its intended indication and
(iv) FDA approval of a pertinent NDA. If the drug has been previously approved,
then the approval process is similar, except that certain toxicity tests
normally required for the IND may not be necessary. Even with previously
approved drugs, additional toxicity testing may be required when the delivery
form is substantially changed. Because the Company's OT-system, by design,
produces high drug concentrations at the surface of the oral mucosa, new
toxicity tests at this site may need to be performed. In addition to the
foregoing, the FDA requires proof that the product delivers sufficient
quantities of the drug to the bloodstream to produce the desired therapeutic
result.




                                      12
<PAGE>   13



      The results of product development, preclinical studies and clinical
studies and other information are submitted to the FDA in an NDA seeking
approval for the marketing and interstate commercial shipment of the drug. The
FDA may deny an NDA if applicable regulatory criteria are not satisfied or may
require additional clinical or other testing. Even if such data are submitted,
the FDA may ultimately decide that the NDA does not satisfy the criteria for
approval. If the FDA does ultimately approve the product, it may require, among
other things, postmarketing testing, including potentially expensive Phase IV
studies, and surveillance to monitor the safety and effectiveness of the drug.
In addition, the FDA may in some circumstances impose restrictions on the use
of the drug that may be difficult and expensive to administer and almost always
seeks to require prior approval of promotional materials. Product approvals may
be withdrawn if compliance with regulatory requirements is not maintained or if
serious problems occur after the product reaches the market. Finally, the FDA
requires reporting of certain information that becomes known to a manufacturer
of an investigational or approved drug.

      Each domestic drug product manufacturing establishment must be registered
with, and essentially approved by, the FDA. In addition, each such
establishment must inform the FDA of every drug product it has in commercial
distribution and keep such list updated. Establishments handling controlled
substances must be licensed and are inspected by the DEA. Anesta has a current
DEA license appropriate for handling the substances it uses in its facilities.
Domestic establishments are also subject to inspection by the FDA for
compliance with cGMP regulations before or after an NDA has been filed and
thereafter, at least biannually. The labeling, advertising and promotion of
drug products also must be in compliance with pertinent FDA regulatory
requirements. Failures to comply with applicable requirements relating to
production, distribution or promotion of a drug product can lead to FDA demands
that production and shipment cease, and, in some cases, that products be
recalled, or to enforcement actions that can include seizures, injunctions and
criminal prosecution. Finally, manufacturers of drug products seeking FDA
approval via an NDA are also required, due to recently introduced user fee
requirements, to make payments to the FDA at various stages of the approval
process. In addition, such payments must also be made in association with
annual establishment registration.

      To market its products abroad, the Company is also subject to numerous
and varying foreign regulatory requirements, implemented by foreign health
authorities, governing, among other things, the design and conduct of human
clinical trials, pricing regulations and obtaining marketing approval. The
approval procedure may vary among countries and can involve additional testing,
and the time required to obtain approval may differ from that required to
obtain FDA approval. At present, foreign marketing authorizations are applied
for at a national level, although within the European Union (EU) certain
registration procedures are available to companies wishing to market a product
in more than one EU member country. If a regulatory authority is satisfied that
adequate evidence of safety, quality and efficacy has been presented, marketing
authorization is almost always granted. The foreign regulatory approval process
includes all of the risks associated with obtaining FDA approval set forth
above. Approval by the FDA does not ensure approval by other countries.

      Various aspects of the Company's business and operations are also
regulated by a number of other governmental agencies including the DEA, U.S.
Department of Agriculture, the Environmental Protection Agency, the
Occupational Safety and Health Administration as well as by other federal,
state and local authorities. In addition, international sales are regulated by
numerous foreign authorities.

PRODUCT LIABILITY INSURANCE

      The testing, marketing and sale of human pharmaceutical products involves
unavoidable risks. The use of any of the Company's potential products in
clinical trials and the sale of any of its products may expose the Company to
potential liability resulting from the use of such products. Such liability
might result from claims made directly by consumers or by regulatory agencies,
pharmaceutical companies or others selling such products. The Company currently
has clinical trial and product liability insurance coverage. The Company will
seek to maintain and appropriately increase such insurance coverage as clinical
development of its product candidates progresses and if and when its products
are ready to be commercialized.

      Anesta has agreed to indemnify Abbott against certain liabilities arising
from Anesta's negligence or willful misconduct in its research and development
activities under the agreement, or its manufacture, use or handling of licensed
products or its breach of the agreement or errors or inaccuracies in the
technology Anesta 


                                      13

licensed to Abbott, if such errors or omissions resulted from Anesta's
negligence or willful misconduct. Abbott has agreed to indemnify Anesta against
certain liabilities arising from Abbott's, or its affiliate's or sublicensee's,
negligence or willful misconduct in the manufacture, use or distribution of
licensed products or its breach of the agreement, except to the extent such
liabilities arise from errors or inaccuracies in Anesta's technology resulting
from Anesta's negligence or willful misconduct.

HUMAN RESOURCES

      As of December 31, 1996, Anesta employed 58 individuals, of whom
approximately 27 hold Ph.D., M.D. or other advanced degrees. Of its total
workforce, 44 employees are engaged in research and development activities and
14 are devoted to commercial, business development and administrative
activities. A significant number of the Company's management and professional
employees have had prior experience with major international pharmaceutical,
biotechnology or medical products companies. Anesta believes that it maintains
good relations with its employees. The Company's success will depend in large
part upon its ability to attract and retain these and future employees. The
Company faces competition in this regard from other companies, research and
academic institutions and government entities.

ITEM 2.  PROPERTIES

         On December 31, 1996, the Company's administrative offices and
research laboratories comprised approximately 28,000 square feet located in
Salt Lake City, Utah. During 1997, the Company will remodel approximately
11,000 additional square feet for office, laboratory and manufacturing space.
The lease covering these facilities expires March 31, 2000, with two five year
renewal options. The Company anticipates that the current and remodeled
facilities will meet the Company's needs through 1998.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATION

RESULTS OF OPERATIONS

     YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

Revenues.

Total revenues decreased by $78,400 or 4.7% during 1996 as compared to 1995 and
increased by $826,400 or 97.2% between 1995 and 1994. The increase between 1995
and 1994 was primarily a result of revenue recognized pursuant to a 1995
collaborative agreement with Abbott Laboratories (Abbott) relating to the Actiq
cancer pain program (See Note 10 to Financial Statements). Substantially all
revenues in all years were from development funding and milestone payments
under collaborative agreements with Abbott relating to the Actiq cancer pain
program. Amounts earned under the collaborative agreements with Abbott may vary
substantially in the future.

Under the Company's agreement with Abbott, Abbott manufactures Fentanyl Oralet
and sells it to the Company at a price which reflects Abbott's cost of
manufacturing. The Company then sells the product to Abbott at a price related
to Abbott's selling price which results in a gross profit to the Company
ranging from approximately 40-70%. In addition, the Company is entitled to
receive a royalty on product sales by Abbott.

Operating Expenses.

Research and development expenses increased by $3,075,400 or 59% during 1996 as
compared to 1995 and by $2,018,200 or 63% between 1995 and 1994. The increase
in research and development expenses in 1996 and 1995 was due primarily to
higher expenditures for the Actiq Cancer Pain Program (See Note 10 to Financial
Statements), new product development and other expenditures for product
development, including clinical trials. The Company expects that its research
and development expenses will grow significantly during 1997 as a result of
increased expenses related to the hiring of additional personnel, preclinical
studies, clinical trials, product development and process development
activities.

Depreciation expense increased by $80,000 or 51% during 1996 as compared to
1995 and by $55,100 or 54% between 1995 and 1994. The increase in 1996 is
primarily due to a decrease in the estimated useful life of specific leasehold
improvements and the increase in 1995 is primarily due to the Company's
remodeling of new facilities.

Marketing, general and administrative expenses increased by $1,317,600 or 59%
during 1996 as compared to 1995 and by $890,400 or 67% between 1995 and 1994.
The increase in 1996 was due primarily to higher expenditures for corporate
development activities, marketing research, Actiq pre-marketing activities,
rent on new facilities, patent activities and equipment leasing. The increase
in 1995 was due primarily to higher expenditures resulting from additional
executives and employees, increased support required for research and
development, patent and corporate development activities. The Company expects
that its marketing, general and administrative expenses will increase
significantly during 1997 as a result of the increased support required for
research and development, marketing research, Actiq pre-launch market
development activities, patent and corporate development activities.

Non Operating Income (Expense).

Interest income increased by $592,500 during 1996 as compared to 1995 and by
$482,200 between 1995 and 1994. The increase in 1996 is primarily due to
invested net proceeds of $27,858,225 from the Company's secondary offering in
June 1996. The increase in 1995 is primarily due to higher interest rates,
partially offset by lower average balances invested.

Interest expense increased by $11,600 during 1996 as compared to 1995 and by
$82,300 between 1995 and 1994. The increase in both years is primarily due to
interest expense related to borrowings on the Company's revolving/term loan.



                                      18

Income Taxes.

As of December 31, 1996, the Company had net operating loss carryforwards of
approximately $18 million and research and development tax credit carryforwards
of $555,000 that expire from 2003 to 2011. A portion of the Company's net
operating loss and research and development tax credit carryforwards are
subject to an annual limitation in future periods pursuant to the "change in
ownership" rules under section 382 of the Internal Revenue Code of 1986, as
amended. Based upon the amount of carryforwards subject to limitation, the date
the limitation arose, and the estimated value of the Company on the change of
ownership date, the Company believes that the limitation will not have a
material impact on the future use of net operating loss and research and
development tax credit carryforwards. The Company's ability to realize the
benefit of the deferred tax asset related to the net operating loss and
research and development tax credit carryforwards will depend on the generation
of future taxable income. Because the Company's operations are not currently
generating taxable income, the Company believes a full valuation allowance
should be provided (See Note 9 to Financial Statements).

Accounting Change.

Effective January 1, 1995, the Company changed its method of accounting for
external legal costs related to patents. Prior to the change, the Company
capitalized these costs and amortized them over the term of the related patent.
Under the new method, these costs are expensed as incurred.

Net Loss.

As a result of the increase in research and development, marketing, general and
administrative activities and other factors discussed above, the net loss for
1996 was $8,689,800 or $1.02 per share as compared to $5,741,800 or $0.80 per
share for 1995 and $2,949,200 or $0.51 per share in 1994. The net loss for 1995
includes the cumulative effect of a change in accounting for patent costs of
$1,041,000 or $0.15 per share.

LIQUIDITY AND CAPITAL RESOURCES

Prior to January 1994, the Company had funded its operations primarily through
private equity financings and through contract payments pursuant to the
Company's agreements with Abbott. In February 1994, the Company realized net
proceeds of $28,538,350 through the issuance of common stock in an initial
public offering and approximately $1,426,000 from the exercise of warrants held
by Abbott. In conjunction with the conversion of preferred stock, a one time
payment of accrued dividends of $491,884 was made in February 1994.

In June 1996 the Company realized net proceeds of $27,858,225 through the
issuance of common stock in a secondary offering. As of December 31, 1996, the
Company had cash and cash equivalents totaling $22,807,600, $1,377,000 in a
certificate of deposit used as collateral for a revolving/term loan as
described below and $17,173,900 in marketable debt securities which are
available for sale. Thus cash, cash equivalents, certificate of deposit and
marketable debt securities totaled $41,358,600 as of December 31, 1996. Cash in
excess of immediate requirements is invested according to the Company's
investment policy, which provides guidelines with regard to liquidity and
return, and, wherever possible, seeks to minimize the potential effects of
concentration of credit risk.

The Company's use of cash in operating activities increased by $3,584,500
during 1996 as compared to 1995 and by $2,261,700 between 1995 and 1994. The
increase in cash used was a direct result of the increase in research and
development and marketing, general and administrative activities discussed
above.

During 1996, the Company made capital expenditures of approximately $53,300 as
compared to capital expenditures of $1,591,900 and $361,000 in 1995 and 1994
respectively. The increase in capital expenditures in 1995 was due to the
Company's remodeling of new facilities. In order to finance the capital
expenditures, the Company, in January 1995, secured a revolving/term loan in
the amount of $1,500,000 which is collateralized by a $1,530,000 certificate of
deposit purchased in 1995. This loan converted to a 10 year term loan on May
15, 1995.



                                      19
<PAGE>   20

During 1996 the Company paid $16,400 on capital lease obligations as compared
to $35,500 and $56,500 in 1995 and 1994 respectively.

The Company expects to continue to incur substantial expenses related to the
continuation and expansion of research and development, including clinical
trials, and increased marketing, general and administrative activities over at
least the next several years. The Company anticipates that the existing cash,
cash equivalents and marketable debt securities, and interest earned thereon
provides adequate working capital through 1999.

The Company's working capital requirements may change depending on numerous
factors, including the following; the progress of the Company's research and
development programs, the results of clinical studies, the number and nature of
the indications the Company pursues in clinical studies, the timing of
regulatory approvals, technological advances, determinations as to the
commercial potential of the Company's products, the status of competitive
products, the establishment of collaborative relationships with other companies
and other factors.

In June 1996, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 125, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities". SFAS No. 125
becomes effective at the beginning of 1997. The Company does not believe that
SFAS No. 125 will have a significant impact on the financial statements of the
Company.

In February 1997, the FASB issued SFAS No. 128, "Earnings Per Share" which
specifies the computation, presentation, and disclosure requirements for
earnings per share. The Company will have to implement SFAS No. 128 in the
fourth quarter of 1997. The impact of the adoption of SFAS No. 128 on the
Company's financial statements has not been determined.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA



                       Report of Independent Accountants





To the Shareholders of
Anesta Corp.:

We have audited the accompanying balance sheets of Anesta Corp. (a development
stage company) as of December 31, 1996 and 1995, and the related statements of
operations, changes in stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1996 and for the period from
inception (August 1, 1985) 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 Anesta Corp. (a development
stage company) as of December 31, 1996 and 1995, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1996, and for the period from inception (August 1, 1985) to
December 31, 1996, in conformity with generally accepted accounting principles.

As discussed in Note 2 to the financial statements, effective January 1, 1995
the Company changed its method of accounting for external legal costs related
to patents.

1.   Significant Accounting Policies:

     Development Stage Activities

     Since its inception in August 1985, Anesta Corp. (Anesta or the Company)
     has been a development stage company engaged in the research, development
     and commercialization of pharmaceutical products incorporating its
     proprietary oral transmucosal drug delivery systems. The Company has been
     unprofitable to date and expects to incur additional operating losses over
     the next few years, primarily due to the expansion of its research and
     development programs, including formulation development, pilot
     manufacturing capabilities, preclinical studies and clinical trials. As of
     December 31, 1996, the Company's accumulated deficit was approximately
     $20.4 million.

     Anesta is the worldwide licensee of technology obtained pursuant to
     technology license agreements with the University of Utah Research
     Foundation (UURF). The license agreements, which remain in effect for the
     life of the applicable patents, may be assigned only with prior written
     consent of UURF (see Note 8).

     Revenues recognized to date represent revenues under research and
     development contracts and the initial sales of the Company's first product
     (Fentanyl Oralet(R)). The Company's ability to achieve profitability
     depends in part upon its ability alone, or with others, to commercialize
     successfully its first product, to complete development of its proposed
     products, to obtain required regulatory approvals and to manufacture and
     market such proposed products (see Note 10).

     Cash Equivalents

     The Company considers all highly liquid debt instruments purchased with
     original maturities of three months or less to be cash equivalents.
     Substantially all of the Company's cash and cash equivalents are held in
     two financial institutions in San Francisco, California.

     Investment in Marketable Debt Securities:

     The Company's investment in marketable debt securities is classified as
     available-for-sale and carried at market value, with the unrealized gain
     or loss, net of deferred taxes, reflected as a separate component of
     stockholders' equity. Gross realized gains and losses, cost determined
     using the specific identification method, have not been material.

     Furniture and Equipment and Leasehold Improvements

     Expenditures that materially increase asset lives are capitalized at cost,
     while normal maintenance and repairs are expensed as incurred.
     Depreciation is reported on a straight-line basis over the estimated
     useful lives of the assets, or the term of the building lease, which range
     from 3 to 15 years.

     The cost and related accumulated depreciation of assets sold or otherwise
     disposed of are removed from the accounts and the gain or loss is
     reflected in the statement of operations.

     Income Taxes

     The Company accounts for income taxes in accordance with Statement of
     Financial Accounting Standards (SFAS) No. 109, Accounting For Income
     Taxes. Deferred income taxes are provided for differences between the
     financial statement and tax bases of assets and liabilities using enacted
     future tax rates.

     Revenue Recognition

     The Company recognized revenues from contract research based on qualifying
     expenditures. Research and development expense in the accompanying
     statements of operations includes funded and unfunded amounts.

     Net Loss Per Share

     Net loss per common share is computed on the weighted average number of
     common and common equivalent shares outstanding during each period. Common
     stock equivalents consist of convertible preferred stock, common stock
     options and warrants. Common equivalent shares are excluded from the
     computation when their effect is antidilutive. The net loss per share for
     the year ended December 31, 1994 has been adjusted to reflect the $491,884
     of dividends paid on the convertible preferred stock which increased the
     net loss attributable to common shareholders to $(3,450,337) or $(.51) per
     share. Net loss per common share for the period from inception to December
     31, 1996 has not been presented as such information is not considered to
     be relevant or meaningful.

     If the conversion of the Series A Preferred Shares into common stock had
     occurred on January 1, 1994, the net loss per common share would have been
     $(.50) for the year ended December 31, 1994.

     Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

     Reclassifications

     Certain amounts of the prior year have been reclassified to conform to the
     current year's presentation. These reclassifications had no effect on net
     income or total assets.

2.   Accounting Change:

     Effective January 1, 1995, the Company changed its method of accounting
     for external legal costs related to patents. Prior to the change, the
     Company capitalized these costs and amortized them over the term of the
     related patent. Under the new method, these costs will be expensed as
     incurred. The Company believes that the change will provide a better
     comparison with the Company's industry peers, the majority of which
     expense these costs.

2.   Accounting Change, Continued

     The cumulative effect of this accounting change for years prior to 1995,
     which is shown separately in the statement of operations for 1995,
     resulted in a charge to operations of $1,041,047 or $.15 per share of
     common stock. The effect of this change on 1995 results of operations was
     to increase the net loss by approximately $310,000.

     The pro forma amount presented below for 1994 reflects the effect of
     retroactive application on net loss and net loss per common share had the
     new method been in effect at the beginning of the year.

6.   Stock Based Compensation Plan:

     The Company maintains three stock option plans: the 1989 Stock Option Plan
     (the "1989 Plan"), the 1993 Stock Option Plan (the "1993 Plan"), and the
     1993 Non-Employee Directors' Stock Option Plan (The "Non-Employee
     Directors' Plan").

     The 1989 Plan provides for the issuance of nonqualified stock options
     ("NQSOs") to employees and directors of and consultants to the Company.

     The 1993 Plan provides for the issuance of Incentive Stock Options
     ("ISOs") and NQSOs to employees and directors of and consultants to the
     Company. The Non-Employee Directors' Plan provides for the issuance of
     NQSOs to non-employee members of the Company's Board of Directors who are
     not prohibited by their employer from receiving options. Additionally, the
     Company has granted NQSOs to non-employee Directors and consultants on an
     individual basis and not under a plan.

     Under the 1989 Plan, NQSOs to purchase a total of 250,000 shares were
     authorized for issuance, of which 85,753 options were outstanding and
     77,399 options were exercisable at December 31, 1996. All options have
     been granted at the market price of the Company's common stock at the date
     of grant. The NQSOs vest over a period not to exceed four years from the
     date of grant and terminate five years from the date of grant.

     Under the 1993 Plan, ISOs and NQSOs to purchase a total of 750,000 shares
     were authorized for issuance, of which 842,939 options were outstanding
     and 271,962 options were exercisable at December 31, 1996. During 1996,
     the Board of Directors authorized an additional 450,000 shares subject to
     stockholder approval at the 1997 annual meeting. All options have been
     granted at the market price of the Company's common stock at the date of
     grant. The ISOs and NQSOs vest over a period not to exceed four years from
     the date of grant and terminate from five to ten years from the date of
     grant.

     Under the Non-Employee Directors' Plan, NQSOs to purchase a total of
     150,000 shares were authorized for issuance, of which 58,500 options were
     outstanding and 16,000 options were exercisable at December 31, 1996. All
     options have been granted at the market price of the Company's common
     stock at the date of grant. The NQSOs vest over a period not to exceed
     four years from the date of grant and terminate five years from the date
     of grant.

     The Company has granted NQSOs to purchase shares on an individual basis
     and not under a plan, on terms similar to the 1989 Plan. At December 31,
     1996, 14,360 options were outstanding and 5,712 options were exercisable.

     The Company has adopted the provisions of SFAS No. 123. Under these
     provisions, the Company is allowed to continue to apply Accounting
     Principles Board Opinion No. 25 and related interpretations in accounting
     for its option plans. Accordingly, no compensation expense has been
     recognized as options are granted at the stock's then market price. Had
     compensation expense for the Company's stock-based compensation plans been
     determined based on the fair value at the grant dates for awards under the
     option plans as recommended by SFAS No. 123, the Company's net loss and
     loss per share would have been increased to the pro forma amounts
     indicated below:

</TABLE>

          NOTE:  Primary and fully diluted loss per share are essentially the 
                 same.

     The SFAS No. 123 method of accounting has not been applied to options
     granted prior to January 1, 1995. The pro forma compensation expense may
     not be representative of such expense in future years.

     The fair value of each option grant is estimated on the date of grant
     using the Black-Scholes option-pricing model with the following
     weighted-average assumptions used for grants in 1995 and 1996,
     respectively: expected volatility of 83 percent, risk-free interest rates
     of 5.4 - 7.8 percent, expected lives of 5 - 10 years, and a dividend yield
     of zero for all years.

     Changes in all outstanding options are as follows:

     In November 1993, the Company adopted the Employee Stock Purchase Plan
     (the "Purchase Plan"), authorizing the issuance of 250,000 shares pursuant
     to purchase rights granted to employees of the Company. Participants may
     use up to 10% of their compensation to purchase the Company's common stock
     at the end of each year for 85% of the lower of the beginning or ending
     stock price in the plan period. As of December 31, 1996, there were
     226,778 shares available for issuance under the Purchase Plan.
     Compensation expense under the fair value method of SFAS No. 123 is not
     significant relative to shares purchased under the Purchase Plan for the
     years ending December 31, 1996 and 1995.

7.   Capital Stock:

     The Company has 1,000,000 shares of authorized preferred voting shares
     with a par value of $.001. The Company also has 50,000 shares of
     authorized non-voting preferred stock with a par value of $.10. At
     December 31, 1996 and 1995 there were no preferred voting or preferred
     non-voting shares issued and outstanding.

     In conjunction with the Company's initial public offering in January 1994,
     the Series A Preferred Shares were converted into common stock and accrued
     dividends of $491,884 were paid. This amount is reflected in the
     accumulated deficit.

     In June 1996, the Company closed a secondary offering of 2,000,000 shares
     of common stock at an offering price of $15.00 per share resulting in net
     proceeds to the Company of $27,858,225.

8.   Technology License Agreement:

     In September 1985, the Company obtained an exclusive worldwide license
     from UURF to use technology and knowledge developed or to be developed
     under Dr. Theodore H. Stanley's direction at the University of Utah, for
     anesthetic and other drug delivery systems based on oral transmucosal
     technology. In return, the UURF received 6,000 shares of Company stock and
     certain royalty rights based on product sales incorporating the
     technology.

     The license expires on the date of the last expiring patent which occurs
     in 2010.

                                   _________


9.   Income Taxes:

     The provision for income taxes for the years ended December 31, 1996, 1995
     and 1994 relates solely to state income taxes.

     Net operating losses (NOLs) totaling approximately $18 million are
     available to offset future taxable income, and research and development
     (R&D) tax credits totaling approximately $555,000 are available to offset
     future tax liabilities. The NOLs and the R&D tax credit carryforwards
     expire from 2003 to 2011.

     The Company's utilization of approximately $1,380,000 of the NOLs against
     future taxable income will be subject to an annual limitation of
     approximately $140,000 per year because of a cumulative change in
     ownership within a three-year period exceeding 50%. Approximately $110,000
     of the R&D tax credit carryforwards is subject to the same annual
     limitation, under the constraint that the total NOLs must be utilized
     before the R&D credits may be used. To the extent the $140,000 annual
     limitation is not fully utilized in any given year, the unused portion of
     the NOLs and the R&D tax credit carryforwards for potential utilization in
     future years.

     SFAS No. 109 requires that a valuation allowance be provided if it is more
     likely than not that some portion or all of a deferred tax asset will not
     be realized. The Company's ability to realize the benefit of its deferred
     tax asset will depend on the generation of future taxable income. Because
     the Company's operations are not currently generating taxable income, the
     Company believes that a full valuation allowance should be provided. The
     valuation allowance increased $2,779,000 during 1996 and $2,694,000 during
     1995, primarily as a result of the increase in net operating loss
     carryforwards.

     The components of the net deferred tax asset as of December 31, 1996 and
     1995 under SFAS 109 are as follows:

10.   Research and Development:

      In December 1989, the Company entered into a research and development,
      license, supply and distribution agreement with Abbott Laboratories
      Hospital Products Division (Abbott). Under the agreement as amended, the
      Company granted to Abbott the exclusive right to make, use and sell in
      the U.S. oral transmucosal products resulting from technology owned or
      licensed by the Company consisting of Oral Transmucosal Fentanyl Citrate
      (OTFC(R)) or other central nervous system acting drugs or intermediates
      thereof used for premedication, sedation, analgesia, diagnostic
      procedures, emergency room, post-operative pain, burn treatment or
      cancer-related pain management. The first product developed under this
      agreement is being marketed for premedication (sedation/analgesia) under
      Abbott's trademark Fentanyl Oralet. The second product under the
      agreement will be marketed for cancer pain by Abbott under Anesta's
      trademark Actiq(TM). Substantially all of the Company's revenues,
      accounts receivable, certain accrued research and development costs, and
      unearned advance royalty amounts are a result of the various agreements
      and transactions with Abbott.

      Under the Company's agreement with Abbott, Abbott manufactures Fentanyl
      Oralet and Actiq and sells these products to the Company at a price which
      reflects Abbott's cost of manufacturing. The Company then sells the
      product to Abbott at a price related to Abbott's selling price which
      results in a gross profit to the Company ranging from approximately
      40-70%. In addition, the Company is entitled to receive a royalty on
      product sales by Abbott.

      Effective March 31, 1995, the Company entered into a 1995 funding
      agreement with Abbott, under which Abbott agreed to provide up to
      $1,500,000 of funding during 1995 to further the clinical development of
      Actiq to treat cancer-related pain (the "Actiq Cancer Pain Program").
      Additionally, the Company entered into a 1996 funding agreement with
      Abbott, effective September 8, 1995, under which Abbott agreed to provide
      up to an additional $1,500,000 of funding during 1996 for the Actiq
      Cancer Pain Program. The funding was to be provided for qualifying work
      performed and expenses incurred by the Company during 1995 and 1996 in
      connection with the Actiq Cancer Pain Program. Under the agreements, the
      Company agreed to provide additional funding required for this program
      and to complete certain program milestones.

      By agreement, Abbott has committed to pay a total of $10.05 million to
      the Company to fund the clinical development of Fentanyl Oralet and Actiq
      and to obtain regulatory approval for these products. During 1996, 1995
      and 1994, the Company received $1,500,000, $1,125,000 and $1,050,000, and
      incurred $5,430,252, $2,530,215 and $1,700,086 of costs relating to the
      agreements, respectively. Revenue of $1,500,000, $1,500,000 and $799,510
      related to the agreements was recognized in 1996, 1995 and 1994,
      respectively. At December 31, 1996 and 1995, accounts receivable relating
      to the agreements totaled $375,000. Abbott is also obligated to pay the
      Company $300,000 upon receipt of FDA approval of Actiq to treat cancer
      pain. In connection with such development funding, Abbott was granted
      warrants to purchase 1,202,840 shares of the Company's common stock at
      prices ranging from $1.00 to $2.40 per share. These warrants were
      exercised upon the closing of the Company's IPO in January 1994 resulting
      in net proceeds to the Company of $1,426,000.

      Effective August 31, 1995, the Company entered into another agreement
      with Abbott whereby Abbott has agreed to be the Company's contract
      manufacturer for clinical and commercial supplies of OTFC products for
      territories outside the U.S. The parties have agreed to consult with each
      other regarding collaborative agreements with other companies and
      negotiate in good faith as to specific terms regarding product supply by
      Abbott to any Anesta licensees.

11.   Unearned Advance Royalty Revenues:

      Effective October 12, 1995, the Company entered into an amendment to a
      prior agreement between Abbott International (A.I.) and the Company to
      provide the Company the right to terminate or cause to become
      nonexclusive A.I.'s license rights to OTFC products in one or more
      countries in the world except the U.S. The amendment also eliminated
      $100,000 of the $450,000 unearned advance royalty obligation, which
      amount was recognized as royalty revenue during the year ended December
      31, 1995.

12.   Leases:

      In December 1994, the Company entered into a five year operating lease
      agreement for a building which has two additional five year renewal
      options. During 1996 and 1995 the Company also entered into operating
