                               PROSPECTUS SUMMARY


   This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully, including the "Risk Factors"
section.

Our Company

   We are a specialty pharmaceutical company that applies proprietary
technologies to develop new drugs and improved formulations of existing drugs
for the prescription pain management market. We believe that our product
candidates address unmet medical needs for breakthrough cancer pain,
postoperative pain, lower-back pain, pain due to orthopedic injury, dental
pain and other indications. We believe our product candidates offer a
combination of enhanced pain relief, improved side effect profiles and faster
onset of pain relief compared to currently available treatments. Our lead
product candidates have demonstrated safety and effectiveness in early- and
mid-stage clinical trials and we expect to begin late-stage clinical trials in
the second half of 2002.

Our Opportunity

   Drugs are a key element in the treatment of pain. The worldwide market for
therapeutics to manage pain is expected to grow from $22 billion in 2000 to
$30 billion in 2007 according to Frontline Strategic Management Consulting,
Inc. Our product candidates target a $3.4 billion subsegment of the worldwide
pain management market.

Our Product Candidates


   We are developing prescription drugs for the treatment of a variety of acute
and chronic moderate-to-severe pain syndromes. We selected our product
candidates based on our belief that they offer significantly lower clinical,
regulatory and commercial risk profiles as compared to new chemical entities.
All of our product candidates contain drugs approved for other uses by the
U.S. Food and Drug Administration, or FDA. We are developing proprietary
formulations for these drugs in order to deliver therapeutic levels into the
bloodstream through fast and effective routes of administration.


   Our current product candidates according to clinical indication and their
stages of clinical development in the United States and the United Kingdom
are:


                                                                         
   Product Candidate             Clinical Indication                           Development Stage
   -----------------         -----------------------                           -----------------
   Intranasal Ketamine       Acute Pain and Acute Episodes of                 Phase II
                             Chronic Moderate-to-Severe Pain
   Intranasal Morphine       Acute Pain and Acute Episodes of                 Phase II
                             Chronic Moderate-to-Severe Pain
   Intravenous Diclofenac    Acute Moderate-to-Severe Pain                    Phase II
   Intranasal Fentanyl       Acute Episodes of Chronic                        Preclinical
                             Moderate-to-Severe Pain



   Intranasal Ketamine

   Our intranasal ketamine product candidate is in clinical development for the
treatment of syndromes associated with acute and chronic moderate-to-severe
pain. Ketamine is an FDA-approved drug that has been in clinical use for over
25 years for general anesthesia. At lower doses than that approved for use as
an anesthetic, ketamine has been reported to be an effective analgesic for the
treatment of breakthrough pain, postoperative pain and pain associated with
emergency medical procedures. We have licenses to two U.S. patents and their
foreign counterparts directed towards the use of ketamine to manage pain and
the administration of ketamine through the nasal route.


                                       1


   In the third quarter of 2001, we successfully completed three Phase II
clinical trials evaluating the safety and effectiveness of intranasal ketamine
for the treatment of acute and chronic moderate-to-severe pain following
dental surgery and for breakthrough episodes of chronic malignant pain. The
results of these studies demonstrated that intranasal ketamine provides rapid
onset of pain relief with dose-related effectiveness and duration of effect,
and appears to be well-tolerated. Based on the results of these studies, we
believe that intranasal ketamine may offer a safe, non-opioid alternative for
the treatment of moderate-to-severe postoperative pain and breakthrough pain.
To date, we have enrolled a total of 118 patients in our intranasal ketamine
clinical trials. We expect to present the data from our Phase II clinical
trials, in addition to our proposed Phase III clinical trial designs, to the
FDA in the first half of 2002.


   Intranasal Morphine

   Our intranasal morphine product candidate is in clinical development for the
treatment of syndromes associated with acute pain and acute episodes of
chronic pain. Morphine is a strong opioid analgesic that is used for the
relief of acute and chronic moderate-to-severe pain and is the drug of choice
for pain associated with cancer. Orally delivered morphine products may not
provide rapid relief of pain and demonstrate considerable patient-to-patient
variability in absorption. Injectable formulations of morphine provide rapid
and effective pain relief, but administration often requires professional
assistance or hospitalization. We believe our intranasal morphine product
candidate would provide significant medical benefit over oral and injectable
formulations as it combines patient convenience and ease of use with the rapid
onset of pain relief and the well-accepted potency of injectable delivery
routes. We have licenses to two U.S. patents and their foreign counterparts
directed towards the use of intranasal morphine.


   Our Phase I clinical trials demonstrated that intranasal morphine is rapidly
absorbed, achieving blood levels typically associated with analgesic
effectiveness in as early as five to ten minutes following administration.
Based on the results of both single and multiple-dose Phase I clinical trials,
we initiated a placebo and comparator-controlled Phase II randomized double-
blind single dose postoperative pain trial. This study compared two dose
levels of intranasal morphine with placebo and with both intravenous and oral
morphine in a total of 225 patients suffering moderate to severe pain
following dental surgery. In this trial we demonstrated that both doses of
intranasal morphine were statistically superior to placebo and statistically
similar to the positive comparators. Intranasal morphine was well tolerated in
this patient population and there were no serious adverse events and no
withdrawals due to adverse events or other safety concerns.  We expect to
complete the study report in the second quarter of 2002 and to present our
data from these clinical trials, in addition to our proposed Phase III
clinical trial designs, to the FDA by mid-2002.


   Intravenous Diclofenac

   Our intravenous diclofenac product candidate is in clinical development for
the management of acute postoperative pain in the hospital setting. Diclofenac
belongs to the class of nonsteroidal anti-inflammatory drugs, or NSAIDs, and
is widely prescribed as an anti-inflammatory agent due to its combination of
effectiveness and tolerability. While currently approved for use in the U.S.
in a variety of oral formulations, as well as a topical and an ophthalmic
formulation, its poor solubility in water and susceptibility to breakdown has
precluded the development of an injectable formulation of diclofenac. We
believe that our intravenous diclofenac product candidate has the potential to
overcome these issues and satisfy the unmet medical need for a safe and
effective injectable NSAID in the hospital setting. We have licenses to one
U.S. patent and its foreign counterparts directed towards intravenous
diclofenac formulations and methods of preparing the same.

   Our intravenous diclofenac product candidate has been evaluated in over 270
human subjects in Phase I clinical trials performed in South Africa and Phase
II clinical trials performed in the United Kingdom, with both sets of trials
conducted on behalf of a third party. Based on the encouraging results of
these clinical trials, combined with the extensive published literature on the
safety and effectiveness of diclofenac, the FDA has indicated that Phase I and
single dose Phase II clinical trials in the United States may be initiated
concurrently upon allowance of an Investigational New Drug Application, or
IND. We anticipate filing an


                                       2

IND for our intravenous diclofenac product candidate in the first half of 2002
in order to initiate a U.S. clinical development program.

Intranasal Fentanyl

   Our intranasal fentanyl product candidate is currently in preclinical
development for the treatment of acute episodes of chronic moderate-to-severe
pain. Fentanyl is a widely prescribed and effective short-acting opioid
analgesic that is 75-100 times more potent than morphine and is used for
treating chronic moderate-to-severe pain, including cancer pain. When
administered using a transdermal patch that provides a controlled rate of
delivery, fentanyl is effective in controlling the chronic pain associated
with cancer. An oral, transmucosal formulation of fentanyl was approved by the
FDA in 1998 specifically for the treatment of breakthrough pain in cancer
patients and is used as an adjunct to the fentanyl patch to control these
flare-up pain episodes.

   We believe that our intranasal fentanyl product candidate could also be used
to complement the fentanyl transdermal patch, as well as controlled-release
formulations of oral opioids, to effectively treat episodes of breakthrough
pain. Our intranasal fentanyl product candidate may offer several advantages
over existing fentanyl-based products for the management of breakthrough pain,
including rapid and consistent onset of action, coupled with certain cost and
safety advantages. In addition, intranasal fentanyl could have advantages for
patients who are unable to swallow, or those with oral ulcerations resulting
from cancer chemotherapy.

Our Strategy

   Our goal is to become a leading specialty pharmaceutical company that
develops and commercializes new drugs for the management of pain in order to
fulfill unmet medical needs. Key elements of our strategy to accomplish this
goal are to:

   o develop new products with reduced clinical and regulatory risk,

   o focus on large markets where our product candidates can address unmet
     clinical needs,

   o focus on clinical development and late-stage product candidates,

   o retain significant rights to our product candidates,

   o use our technology platforms to develop new product candidates and

   o outsource key functions.

                                  RISK FACTORS

   An investment in our common stock involves significant risks. You should
carefully consider the following risk factors before you decide to buy our
common stock.

                          Risks Related To Our Company


We have no product revenues and may need to raise additional capital to
operate our business.


   We are a development-stage company focused on product development and have
not generated any product revenues to date. Until, and if, we receive approval
from the FDA and other regulatory authorities for our product candidates, we
cannot sell our drugs and will not have product revenues. Therefore, for the
foreseeable future, we will have to fund all of our operations and capital
expenditures from the net proceeds of this offering, cash on hand and grants.
We expect that the assumed net proceeds of $43.9 million from this offering
and cash on hand will be sufficient to meet our working capital and capital
expenditure needs for at least the next 12 months. However, our actual capital
requirements will depend on many factors. If we experience unanticipated cash
requirements, we may need to seek additional sources of financing, which may
not be available on favorable terms, if at all. If we do not succeed in
raising additional funds on acceptable terms, we may be unable to complete
planned preclinical studies and clinical trials or obtain approval of our
product candidates from the FDA and other regulatory authorities. In addition,
we could be forced to discontinue product development, reduce or forego sales
and marketing efforts and attractive business opportunities or discontinue
operations.

We have a history of losses and we may never achieve or sustain profitability.

   We have incurred substantial losses since our inception, and we may not
achieve profitability for the foreseeable future, if at all. We incurred a net
loss attributable to our common stockholders of approximately $470,000 for the
period from February 23, 1998 (inception) to December 31, 1998, $1.2 million
in 1999, $23.0 million in 2000 and $11.6 million in 2001. As of December 31,
2001, we had an accumulated net loss attributable to our common stockholders
of $36.3 million. Even if we succeed in developing and commercializing one or
more of our product candidates, we expect to incur substantial net losses and
negative cash flows for the foreseeable future due in part to increasing
research and development expenses, including clinical trials, and increasing
expenses from leasing additional facilities and hiring additional personnel.
As a result, we will need to generate significant revenues in order to achieve
and maintain profitability. We may not be able to generate these revenues or
achieve profitability in the future. Even if we do achieve profitability, we
may not be able to sustain or increase profitability.

We have a limited operating history upon which to base an investment decision.

   We commenced operations in 1998. Our limited operating history may limit
your ability to evaluate our prospects due to our limited historical financial
data and our unproven potential to generate profits. You should evaluate the
likelihood of financial and operational success in light of the risks,
uncertainties, expenses and difficulties associated with an early-stage
business, many of which may be beyond our control, including:

   o our potential inability to continue to undertake preclinical studies and
     clinical trials,

   o our potential inability to obtain regulatory approvals, and

   o our potential inability to manufacture, sell and market our products.

   Our operations have been limited to organizing and staffing our company,
acquiring, developing and securing our proprietary technology and undertaking
preclinical studies and clinical trials of our principal product candidates.
These operations provide a limited basis for you to assess our ability to
commercialize our product candidates and the advisability of investing in our
common stock.


                                       7

If we fail to obtain or maintain necessary regulatory approvals for our
products, or if approvals are delayed or withdrawn, we will be unable to
commercialize our product candidates.

   Government regulation in the United States and other countries has a
significant impact on our business and affects the research and development,
manufacture and marketing of our products. In the United States, the FDA has
broad authority to regulate the distribution, manufacture and sale of drugs.
Foreign sales of drugs are subject to foreign governmental regulation and
restrictions, which vary from country to country. In order to obtain FDA
approval of any of our product candidates, we must submit to the FDA a New
Drug Application, or NDA, demonstrating that the product candidate is safe for
humans and effective for its intended use. This demonstration requires
significant research and animal tests, which are referred to as preclinical
studies, as well as human tests, which are referred to as clinical trials. The
process of obtaining FDA and other regulatory clearances and approvals is
lengthy and expensive. We may not be able to obtain or maintain necessary
approvals for clinical trials or for the manufacturing or marketing of our
products. Failure to comply with applicable regulatory approvals can, among
other things, result in fines, suspension or withdrawal of regulatory
approvals, product recalls, operating restrictions, and criminal prosecution.
In addition, governmental regulations may be established which could prevent,
delay, modify or rescind regulatory approval of our products. Any of these
actions by the FDA, or any changes in FDA regulations, would adversely impact
our business and financial condition.

Our product candidates are in early stages of clinical testing.

   Our three principal product candidates, intranasal ketamine, intranasal
morphine and intravenous diclofenac, are still in the early- to mid-stages of
clinical testing on a limited number of patients. We will need to commit
substantial time and additional resources to conducting further preclinical
studies and clinical trials before we can submit an NDA with respect to any of
these product candidates. Our other product candidate, intranasal fentanyl, is
at a much earlier stage of development and may require extensive preclinical
testing before we can proceed to clinical trials. In addition, before we can
commence clinical trials in the United States on intravenous diclofenac and
intranasal fentanyl, we will have to submit an IND to the FDA. We cannot
predict with any certainty if or when we might submit an NDA for regulatory
approval of any of our product candidates.

If the clinical trials of our product candidates fail, we will not be able to
market our product candidates.

   To receive the regulatory approvals necessary for the sale of our product
candidates, we must demonstrate through human clinical trials that each
product candidate is safe and effective. Positive results from preclinical
studies and early clinical trials do not ensure positive results in clinical
trials designed to permit application for regulatory approval. We may suffer
significant setbacks in clinical trials, even after earlier clinical trials
show promising results. Any of our product candidates may produce undesirable
side effects in humans that could cause us or regulatory authorities to
interrupt, delay or halt clinical trials of a product candidate.

   We, the FDA and foreign or other regulatory authorities may suspend our
clinical trials at any time if we or they believe the trial participants face
unacceptable health risks or if the FDA finds deficiencies in our IND
submissions.

Even if we obtain FDA approval to market our product candidates, they may not
be accepted by physicians and patients.

   Our drugs will not be commercially accepted products unless physicians and
patients determine that our drugs are clinically useful, cost-effective and
safe. Acceptance and use of our drugs will also depend upon a number of
factors including:

   o the cost of our drugs as compared to competing products,

   o the availability of adequate coverage and reimbursement levels from
     government health administration authorities, private or other health
     insurers and other organizations, and


                                       8

   o the effectiveness of our and our licensees' marketing and distribution
     efforts.

Because we expect sales of our current product candidates, if approved, to
generate substantially all of our product revenues for the foreseeable future,
the failure of any of these drugs to find market acceptance would harm our
business and could require us to seek additional financing.

Our product candidates contain controlled substances, the supply of which may
be limited by U.S. government policy and the use of which may generate public
controversy.

   The active ingredients in our current product candidates, including
morphine, ketamine and fentanyl, are listed by the U.S. Drug Enforcement
Agency, or DEA, as Schedule II or III substances under the Controlled
Substances Act of 1970. The DEA regulates chemical compounds as Schedule I,
II, III, IV or V substances, with Schedule I substances considered to present
the highest risk of substance abuse and Schedule V substances the lowest risk.
These product candidates are subject to DEA regulations relating to
manufacturing, storage, distribution and physician prescription procedures.
For example, all regular Schedule III drug prescriptions must be signed by a
physician and may not be refilled. Furthermore, the amount of Schedule III
substances we can obtain for clinical trials and commercial distribution is
limited by the DEA and our quota may not be sufficient to complete clinical
trials or meet commercial demand, if any.

   Products containing controlled substances may generate public controversy.
Opponents of these products may seek restrictions on marketing and withdrawal
of any regulatory approvals. In addition, these opponents may seek to generate
negative publicity in an effort to persuade the medical community to reject
these products. Political pressures and adverse publicity could lead to delays
in, and increased expenses for, and limit or restrict the introduction and
marketing of our product candidates. The FDA may require us to develop a
comprehensive risk management program to reduce the inappropriate use of our
products and product candidates, including the manner in which they are
marketed and sold, so as to reduce the risk of improper patient selection and
diversion or abuse of the product. Developing such a program in consultation
with the FDA may be a time-consuming process and could delay approval of any
of our product candidates. Such a program or delays of any approval from the
FDA could limit market acceptance of the product.

International commercialization of our product candidates faces significant
obstacles.

   We may plan to commercialize some of our products internationally through
collaborative relationships with foreign partners. We have limited foreign
regulatory, clinical and commercial resources. Future partners are critical to
our international success. We may not be able to enter into collaboration
agreements with appropriate partners for important foreign markets on
acceptable terms, or at all. Future collaborations with foreign partners may
not be effective or profitable for us.

   We will need to obtain approvals from the appropriate regulatory, pricing
and reimbursement authorities to market any of our proposed products
internationally, and we may be unable to obtain foreign regulatory approvals.
Pursuing foreign regulatory approvals will be time-consuming and expensive.
The regulations can vary among countries and foreign regulatory authorities
may require different or additional clinical trials than we conducted to
obtain FDA approval for our product candidates. In addition, adverse clinical
trial results, such as death or injury due to side effects, could jeopardize
not only foreign regulatory approval, but may also lead to marketing
restrictions in the United States. Our product candidates may also face
foreign regulatory requirements applicable to controlled substances.


Our preclinical studies and clinical trials depend upon third-party
researchers who are outside our control.

   We depend upon third parties, such as independent investigators,
collaborators and medical institutions, to conduct our preclinical studies and
clinical trials under agreements with us. These third parties are not our
employees and we cannot control the amount of time or resources that they devote
to our programs. These investigators may not assign as great a priority to our
programs or pursue them as diligently as we would if we were undertaking such
programs ourselves. If outside collaborators, including West Pharmaceutical
Services, Inc. with respect to preclinical development of Fentonyl, fail to
devote sufficient time and resources to our preclinical studies and clinical
trials, or if their performance is substandard, the approval of our FDA
applications, if any, and our introduction of new drugs, if any, will be
delayed. These collaborators



                                       9

may also have relationships with other commercial entities, some of whom may
compete with us. If our collaborators assist our competitors at our expense,
our competitive position would be harmed.


We rely exclusively on one party to formulate some of our product candidates
and the loss of this party could harm our business.

   We currently rely on a single formulator, West Pharmaceutical, to formulate
intranasal morphine for our clinical trials. Our agreement with West
Pharmaceutical will expire on September 21, 2002. The parties meet regularly to
discuss the status of the development programs and we submit to West
Pharmaceutical biannual revised product plans, the scope and detail of which we
believe are consistent with industry standards. In addition, West Pharmaceutical
currrently supplies us intranasal morphine for use in our clinical trials.
Although we believe that we can obtain morphine from alternative suppliers, we
may be unable to obtain it on favorable terms, or at all. If we are unable to
obtain sufficient supplies of morphine, our business would be seriously harmed.
If any of our product candidates receives FDA approval, we expect to rely on one
or more third-party contractors to supply our drugs. If our current or future
third-party suppliers cease to supply the drugs in the quantity and quality we
need to manufacture our drug candidates or if they are unable to comply with
good manufacturing practice and other government regulations, the qualification
of additional or replacement suppliers could be a lengthy process and there may
not be adequate alternatives to meet our needs, which would negatively affect
our business. We may not be able to obtain the necessary drugs used in our
products in the future on a timely basis, if at all.


If our sole supplier of chitosan fails to provide us sufficient quantities, we
may not be able to obtain an alternative supply on a timely or acceptable
basis.

   We currently rely on a sole source for our supply of chitosan, a principal
component of our intranasal morphine product candidate. Under our agreement
with West Pharmaceutical, which will expire on September 21, 2002, we are
required to purchase from West Pharmaceutical all of the chitosan required for
use in our intranasal morphine clinical trials, subject to West
Pharmaceutical's ability to supply the full amount we require. There are
relatively few alternative sources of supply for chitosan and we may not be
able to obtain a sufficient supply of chitosan from West Pharmaceutical or
other suppliers, or at all. We may also not be able to find alternative
suppliers in a timely manner that would provide chitosan at acceptable
quantities and prices. Any interruption in the supply of chitosan would
disrupt our ability to manufacture intranasal morphine and could have a
material adverse effect on our business.

We have no experience selling, marketing or distributing products and no
internal capability to do so.

   We currently have no sales, marketing or distribution capabilities. In order
to commercialize our products, if any are approved, we intend to develop
internal sales, marketing and distribution capabilities to target particular
markets for our products, as well as make arrangements with third parties to
perform these services for us with respect to other markets for our products.
We may not be able to establish these capabilities internally or hire
marketing and sales personnel with appropriate expertise to market and sell
our products, if approved. In addition, even if we are able to identify one or
more acceptable collaborators to perform these services for us, we may not be
able to enter into any collaborative arrangements on favorable terms, or at
all.

   If we enter into any collaborative arrangements for the marketing or sale of
our products, our product revenues are likely to be lower than if we marketed
and sold our products ourselves. In addition, any revenues we receive would
depend upon the efforts of our collaborators, which may not be adequate due to
lack of attention or resource commitments, management turnover, change of
strategic focus, business combinations, their inability to comply with
regulatory requirements or other factors outside of our control. Depending
upon the terms of our collaboration, the remedies we have against an under-
performing collaborator may be limited. If we were to terminate a
relationship, it may be difficult or impossible to find a replacement
collaborator on acceptable terms, if at all.


                                       10

We are faced with intense competition and rapid technological change, which
may make it more difficult for us to achieve significant market penetration.
If we cannot compete successfully for market share against other drug
companies, we may not achieve sufficient product revenues and our business
will suffer.

   The market for our product candidates is characterized by intense
competition and rapid technological advances. If our product candidates
receive FDA approval, they will compete with a number of existing and future
drugs and therapies developed, manufactured and marketed by others which use
opioids and NSAIDs as pain management. If our competitors' existing products
or new products are more effective than or considered superior to our future
products, the commercial opportunity for our product candidates will be
reduced or eliminated. Existing or future competing products may provide
greater therapeutic convenience or clinical or other benefits for a specific
indication than our products, or may offer comparable performance at a lower
cost. We face competition from fully integrated pharmaceutical companies and
smaller companies that are collaborating with larger pharmaceutical companies,
academic institutions, government agencies and other public and private
research organizations. If we are successful in penetrating the market for
pain treatment with our product candidates, other companies may be attracted
to the market. Many of our competitors have opioid or NSAID painkillers
already approved or in development. In addition, many of these competitors,
either alone or together with their collaborative partners, are larger than we
are and have substantially greater financial, technical, research, marketing,
sales, distribution and other resources than we do. Our competitors may
develop or market products that are more effective or commercially attractive
than any that we are developing or marketing. Our competitors may obtain
regulatory approvals, and introduce and commercialize products before we do.
These developments could have a significant negative effect on our financial
condition. Even if we are able to compete successfully, we may not be able to
do so in a profitable manner.

If we fail to adequately protect or enforce our intellectual property rights
or secure rights to patents of others, we may be unable to compete
effectively.

   Our success, competitive position and future revenues will depend in part on
our ability and the abilities of our third-party licensors to obtain and
maintain patent protection for our products, methods, processes and other
technologies and to preserve our trade secrets.

   To date, we have licenses to certain patent rights, including rights under
U.S. patents and U.S. patent applications and under foreign patents and patent
applications, related to our product candidates.  We anticipate filing
additional patent applications both in the United States and in other
countries, as appropriate.  The procedures for obtaining an issued patent in
the United States and in most foreign countries are complex.  These procedures
require an analysis of the scientific technology related to the invention and
many legal issues.  Accordingly, we expect that the examination of our patent
applications will be complex and time consuming. We do not know when, or if,
we will obtain additional issued patents for our technologies.

   We cannot predict whether or not:

   o any additional patents will issue and the degree and range of protection
     they will afford us against competitors,

   o others will obtain patents claiming aspects similar to those covered by
     our patents and patent applications,

   o we will need to initiate litigation or administrative proceedings
     regarding our patents, which may be costly whether we win or lose or

   o third parties will find ways to challenge, invalidate or otherwise
     circumvent our patent rights that we currently hold or license.

   The degree and range of protection afforded by any of our licensed patents,
as with all patents, is defined by the breadth of the claims of the patent.
As the components of our product candidates are commercially available to
third parties, it is possible that competitors may design formulations,
propose dosages, or develop methods or routes of administration with respect
to these components that would be


                                       11

outside the scope of the claims of one or more, or of all, of our licensed
patents. This would enable their products to effectively compete with our
product candidates.

   We may have to institute costly legal action to protect our intellectual
property rights. We may not be able to afford the costs of enforcing our
intellectual property rights.  Consequently, we do not know how much, if any,
protection our patents will provide.  A third party might request a court to
rule that our patents are invalid or unenforceable. In such a case, even if
the validity and enforceability of our patents were upheld, a court might hold
that the third party's actions do not infringe our patent.

   The laws of some countries may not protect our intellectual property rights
to the same extent as U.S. laws. For example, methods of treating humans are
not patentable subject matter in many countries outside of the United States.
It may be necessary or useful for us to participate in proceedings to
determine the validity of our foreign patents or those of our competitors,
which could result in substantial cost and divert our efforts and attention
from other aspects of our business.  These and other issues may limit the
patent protection we will be able to secure outside of the United States.

   Our success also depends upon the skills, knowledge and experience of our
scientific and technical personnel, our consultants and advisors as well as
our licensors and contractors.  To help protect our proprietary know-how and
our inventions, we also rely on trade secret protection and confidentiality
agreements, in addition to patents.  However, trade secrets are difficult to
protect.  To this end, we require all of our employees, consultants, advisors
and contractors to enter into agreements that prohibit the disclosure of our
trade secrets and other confidential information and, where applicable,
require disclosure and assignment to us of the ideas, developments,
discoveries and inventions important to our business.  These agreements may
not provide adequate protection for our trade secrets, know-how or other
proprietary information in the event of any unauthorized use or disclosure or
the lawful development by others of such information.  If any of our trade
secrets, know-how or other proprietary information is disclosed, or if third
parties independently discover our trade secrets or proprietary information,
the value of our trade secrets, know-how and other proprietary rights would be
significantly impaired and our business and competitive position would suffer.

   Technology licensed to us by others, or in-licensed technology, is important
to our business.  We may not control the patent prosecution, maintenance or
enforcement of some of our in-licensed technology.  Accordingly, we may be
unable to exercise the same degree of control over this intellectual property
as we would over our internally developed technologies.  Moreover, our rights
to in-licensed technology could be terminated under the terms of our license
agreements, including upon a default by us.  If such a default were to occur
under any of these agreements, we could lose our rights to the in-licensed
technologies or other products that are the subject of that agreement,
including our rights to continue to develop that technology.  The loss of
these technologies, products or rights could harm our business.

A dispute regarding the infringement or misappropriation of our proprietary
rights or the proprietary rights of others could be costly and result in
delays in our research and development activities.

   Our success, competitive position and future revenues will also depend in
part on our ability to operate without infringing on or misappropriating the
proprietary rights of others.   Since our product candidates contain
components that are well known and that have been in use by other companies,
our product candidates could infringe the proprietary rights of third parties.
We are aware of one third party who could allege that certain uses of our
product candidates infringe its proprietary rights.  We do not intend to
market our products for such uses, nor are we aware of any such uses currently
in practice, but we may not be able to avoid claims or liability with respect
thereto because we cannot prevent others from using our products for such uses
in the future.

   Many of our employees and consultants were, and many of our consultants may
currently be, parties to confidentiality agreements with other companies.
While our confidentiality agreements with these employees and consultants
require that they do not bring to us, or use without proper authorization, any
third party's proprietary technology, if they violate their agreements, we
could suffer claims or liabilities.

   If our products, methods, processes and other technologies infringe the
proprietary rights of other parties, we could incur substantial costs and we
may have to:


                                       12

   o obtain licenses, which may not be available on commercially reasonable
     terms, if at all,

   o redesign our products or processes to avoid infringement,

   o stop using the subject matter claimed in the patents held by others,

   o pay damages or

   o defend litigation or administrative proceedings which may be costly
     whether we win or lose, and which could result in a substantial diversion
     of our valuable management resources.

We may not successfully manage our growth.


   Our success will depend upon the expansion of our operations and the
effective management of our growth. We expect to experience significant growth
in the scope of our operations and the number of our employees. If we grow
significantly, such growth will place a significant strain on our management
and on our administrative, operational and financial resources. To manage this
growth, we must expand our facilities, augment our operational, financial and
management systems, internal controls and infrastructure and hire and train
additional qualified personnel. Our future success is heavily dependent upon
growth and acceptance of our future products. If we are unable to scale our
business appropriately or otherwise adapt to anticipated growth and new product
introduction, our business and financial condition will be harmed.


We depend upon Paramount Capital Investments, LLC for all of our current
infrastructure-related administrative services and office support and
equipment.

   Paramount Capital Investments, LLC, an affiliate of one of our principal
stockholders, currently provides all of our office space, some members of our
management and employees and certain administrative and legal assistance at no
cost to us. Paramount also provides us with computer hardware and software and
services related to the development, management and maintenance of our
internal data and file storage, as well as office equipment. The estimated
fair value of the assistance provided by Paramount to us totaled $481,299 for
the twelve months ended December 31, 2001, which has been reflected in the
accompanying financial statements as an expense in that period with a
corresponding deemed capital contribution. We currently do not have an
agreement in place with Paramount governing all aspects of this relationship.
We do, however, have an agreement in place with Paramount under which
Paramount has waived any claim for reimbursement for such assistance, and will
continue to waive any claim for reimbursement for any assistance provided to
us through the end of the third quarter of 2002. If Paramount fails to provide
assistance to us, we will need to obtain similar services from a third party
or develop an internal infrastructure for similar services in order to operate
our business. We also have an agreement with Paramount under which Paramount
assigned to us all rights in all proprietary technology and information
developed with the assistance of Paramount. In addition, we have an agreement
stating that Paramount will maintain our proprietary information in confidence
for a period of ten years from the date they receive such proprietary
information. Due to the existing arrangements, Paramount may be able to exert
influence over our business and affairs.

We currently have no permanent facilities.

   We currently share office space with Paramount Capital Investments on a
rent-free and informal basis. We do not have any contractual rights to
continue that arrangement. We currently have an agreement in place with
Paramount under which Paramount has waived any claim for reimbursement for any
payments regarding this arrangement, and will continue to waive any claim for
reimbursement for any similar payments through the end of the third quarter of
2002. In order to succeed, we will need to lease our own facilities at some
point in the future. If we are unable to acquire these facilities on
acceptable terms, or at all, our business will be harmed.

We may be exposed to liability claims associated with the use of hazardous
materials and chemicals.

   Our research and development activities involve the controlled use of
hazardous materials and chemicals. Although we believe that our safety
procedures for using, storing, handling and disposing of these materials
comply with federal, state and local laws and regulations, we cannot
completely eliminate the risk of

                                       13

accidental injury or contamination from these materials. In the event of such
an accident, we could be held liable for any resulting damages and any
liability could materially adversely affect our business, financial condition
and results of operations. In addition, the federal, state and local laws and
regulations governing the use, manufacture, storage, handling and disposal of
hazardous or radioactive materials and waste products may require us to incur
substantial compliance costs that could materially adversely effect our
business and financial condition.

We rely on key executive officers and scientific and medical advisors, and
their knowledge of our business and technical expertise would be difficult to
replace.


   We are highly dependent on Dr. Leonard Firestone, our Chief Executive
Officer and Chief Medical Officer, as well as other executive officers,
including Douglas A. Hamilton, our Chief Operating Officer and Chief Financial
Officer, Dr. Fred Mermelstein, our President, and Dr. Randi Albin, our Chief
Scientific Officer. We have entered into an employment agreement with Dr.
Firestone that will become effective upon the closing of this offering. In
addition, Dr. Mermelstein devotes only approximately 48% of his business time
to us and the remainder to Paramount Capital Investments. We do not have "key
person" life insurance policies for any of our officers. The loss of the
technical knowledge and management and industry expertise of any of our key
personnel could result in delays in product development, loss of customers and
sales, if any, and diversion of management resources, which could adversely
affect our operating results.


   In addition, we rely on members of our scientific advisory board and
clinical advisors to assist us in formulating our research and development
strategy. All of the members of our scientific advisory board and our clinical
advisors have other jobs and commitments that may limit their availability to
work with us.

If we are unable to hire additional qualified personnel, our ability to grow
our business may be harmed.

   We will need to hire additional qualified personnel with expertise in
preclinical studies, clinical research and trials, government regulation,
formulation and manufacturing and sales and marketing. We compete for
qualified individuals with numerous biopharmaceutical companies, universities
and other research institutions. Competition for such individuals,
particularly in the New York City area, is intense, and we may not be able to
hire sufficient personnel to support our efforts.

We may incur substantial liabilities and may be required to limit
commercialization of our products in response to product liability lawsuits.

   The testing and marketing of medical products entail an inherent risk of
product liability. Although side effects from our clinical trials thus far
have been limited to symptoms known to be associated with these medications,
such as dysphoria, which is a feeling of malaise, and nausea, we may be held
liable if any more serious adverse reactions from the use of our product
candidates occurs. Our product candidates involve a new method of delivery for
potent drugs that require greater precautions to prevent unintended use,
especially since they are designed for patients' self-use rather than being
administered by medical professionals. For example, the FDA may require us to
develop a comprehensive risk management program for our product candidates to
reduce the risk of improper patient selection, diversion and abuse. The
failure of these measures could result in harmful side effects or death. As a
result, consumers, regulatory agencies, pharmaceutical companies or others
might make claims against us. If we cannot successfully defend ourselves
against product liability claims, we may incur substantial liabilities or be
required to limit commercialization of our product candidates. Our inability
to obtain sufficient product liability insurance at an acceptable cost to
protect against potential product liability claims could prevent or inhibit
the commercialization of pharmaceutical products we develop, alone or with
corporate collaborators. We currently carry clinical trial insurance but do
not carry product liability insurance. We, or any corporate collaborators, may
not be able to obtain insurance at a reasonable cost, if at all. Even if our
agreements with any future corporate collaborators entitle us to
indemnification against losses, such indemnification may not be available or
adequate if any claim arises.

                         Risks Related To The Offering

Our stock price could be volatile and the value of your investment could
decline.

   After this offering, you may not be able to resell your shares at or above
the initial public offering price. The trading price for our common stock is
likely to be highly volatile and could be subject to wide fluctuations in
price in response to various factors, many of which are beyond our control,
including:

   o publicity regarding actual or potential clinical results relating to
     products under development by our competitors or us,

   o delay or failure in initiating, completing or analyzing preclinical
     studies or clinical trials or unsatisfactory design or results of these
     tests,

   o achievement or rejection of regulatory approvals by our manufacturers,
     suppliers, distributors, competitors or us,

   o announcements of technological innovations or new commercial products by
     our competitors or us,

   o developments concerning proprietary rights, including patents,

   o developments concerning our collaborations,

   o regulatory developments in the United States and foreign countries,

   o economic or other crises and other external factors,

   o period-to-period fluctuations in our revenue and other results of
     operations,

   o changes in financial estimates by securities analysts, and

   o sales of our common stock.

   We will not be able to control many of these factors, and we believe that
period-to-period comparisons of our financial results will not necessarily be
indicative of our future performance. If our revenues, if any, in any
particular period do not meet expectations, we may not be able to adjust our
expenditures in that period, which could cause our operating results to suffer
further. If our operating results in any future period fall below the
expectations of securities analysts or investors, our stock price may fall by
a significant amount.

   In addition, the stock market in general, and the Nasdaq National Market and
the market for biotechnology companies in particular, has experienced extreme
price and volume fluctuations that may have been unrelated or disproportionate
to the operating performance of individual companies. These broad market and
industry factors may seriously harm the market price of our common stock,
regardless of our operating performance.

We are at risk of securities class action litigation due to our expected stock
price volatility.

   In the past, securities class action litigation has often been brought
against companies following periods of volatility in the market price of their
securities. Due to the expected volatility of our stock price, we may be the
target of securities litigation in the future. Securities litigation could
result in substantial costs and divert management's attention and resources
from our business.

An active trading market for our common stock may not develop.

   Before this offering, there was no public market for our common stock. An
active public market for our common stock may not develop or be sustained
after this offering. We will determine the initial public offering price of
our common stock based on negotiations between the representatives of the
underwriters and our management concerning the valuation of our common stock,
and this price may not be indicative of future market prices. The public
market may not agree with or accept this valuation. The factors to be
considered in determining the initial public offering price of our common
stock, in addition to prevailing market conditions, include:

   o estimates of our business potential and earnings prospects,


                                       15

   o an assessment of our management, and

   o the consideration of these factors in relation to market valuations of
     companies in related businesses.

Because our directors, management and affiliates will retain significant
control over us after this offering, they could control our actions in a
manner that conflicts with our interests and the interests of our
stockholders.


   We anticipate that our officers, directors and individuals or entities
affiliated with our directors, including our largest stockholder, will
beneficially own approximately 39.9% of our outstanding common stock as a
group after this offering closes. Acting together, these stockholders would be
able to exercise significant influence over all matters that our stockholders
vote upon, including the election of directors and the approval of significant
corporate transactions. This concentration of ownership may also delay, deter
or prevent a change in our control and may make some transactions more
difficult or impossible to complete without the support of the stockholders.



We will be subject to the anti-takeover provisions of the Delaware General
Corporation Law, which regulates corporate acquisitions and we have other
anti-takeover provisions that may make it difficult for a third party to
acquire us.


   Delaware law will prevent us from engaging, without the approval of our
board of directors, or two-thirds of our stockholders, in transactions with any
stockholder that controls, together with its affiliates, 15% or more of our
outstanding common stock for three years following the date on which the
stockholder first acquired 15% or more of our outstanding common stock. The
anti-takeover provisions of our charter documents, including, among other
things, division of our board into three classes serving staggered terms and our
board's ability to issue up to 5,000,000 shares of preferred stock, and of the
Delaware General Corporation Law are likely to discourage potential acquisition
proposals and delay or prevent a transaction resulting in a change in control.


If a large number of shares of our common stock are sold after this offering,
the market price of our common stock could decline.

   If our stockholders sell substantial amounts of common stock in the public
market, including shares that we may issue upon the exercise of outstanding
options and warrants, the market price of our common stock could decline. This
could also impair our ability to raise additional capital through the sale of
our equity securities. After this offering, we will have 20,645,327 shares of
common stock outstanding or, if the underwriters exercise their over-allotment
option in full, 21,485,327 shares of common stock outstanding. Of these
shares, the shares sold in this offering will be freely tradeable. The
remaining 15,045,327 shares are "restricted shares" and will become eligible
for sale in the public market at various times after 180 days after the date
of this prospectus, subject to the limitations and other conditions of Rule
144 under the Securities Act.


   In addition, after this offering, the holders of approximately 6,646,635
shares of common stock and warrants to purchase approximately 635,090 shares
of common stock will have registration rights with respect to these shares,
allowing these stockholders to sell these shares in the market simultaneously
with any further public offerings by us of our equity securities.


You will suffer immediate and substantial dilution because the net tangible
book value of shares purchased in this offering will be substantially lower
than the initial public offering price.

   The initial public offering price of the shares of common stock in this
offering will significantly exceed the pro forma as adjusted net tangible book
value per share of our common stock. Any shares of common stock that investors
purchase in this offering will have a pro forma as adjusted net tangible book
value per share of $6.50 per share less than the initial public offering price
paid, assuming an initial public offering price per share of $9.00.
Accordingly, if you purchase common stock in this offering, you will incur
immediate and substantial dilution of your investment.


                                       16

You may suffer additional dilution if current options or warrants are
exercised.

   We have issued options and warrants to acquire our common stock at prices
significantly below the initial public offering price of our common stock in
this offering. When any of these options or warrants are exercised, you will
incur additional dilution. Upon the completion of certain milestones and upon
mutual agreement of the parties, Dr. Stuart Weg, one of our licensors, and
West Pharmaceutical may receive a cash or stock payment from us. If West
Pharmaceutical receives our stock, we will be required to issue the stock at
its then fair market value. If Dr. Weg receives our stock, we will be required
to issue the stock at the average closing price for our shares of common stock
for the ten consecutive trading days immediately preceding the achievement of
such milestones. In addition, upon the completion of certain milestones,
Shimoda Biotech (Proprietary) Ltd. and Farmarc Netherlands B.V. (Registration
No. 2807216) may elect to receive a cash or stock payment from us. If Shimoda
and Farmarc receive our stock, we will be required to issue the stock at the
initial public offering price. If any of these stock payments occur, you will
incur additional dilution. To the extent we raise additional capital by
issuing equity securities in the future, you and our other stockholders may
experience dilution and future investors may be granted rights superior to
those of our current stockholders.


                                       17

                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

limited to, statements about:

   o our product development efforts,

   o anticipated operating losses and capital expenditures,

   o anticipated regulatory filing dates and clinical trial initiation dates,

   o our estimates regarding our capital requirements and our needs for
     additional financing,

   o our estimates for future revenues and profitability,

   o our selection and licensing of product candidates,

   o our ability to attract partners with acceptable development, regulatory
     and commercialization expertise,

   o the benefits to be derived from corporate collaborations, license
     agreements and other collaborative efforts, including those relating to
     the development and commercialization of our product candidates, and

   o sources of revenues and anticipated revenues, including contributions
     from corporate collaborations, license agreements and other collaborative
     efforts for the development and commercialization of our product
     candidates, and the continued viability and duration of those agreements
     and efforts.

                                       18

                                USE OF PROCEEDS

   We estimate that the net proceeds we will receive from the sale of
5.6 million shares of common stock, before payments to Shimoda Biotech
(Proprietary) Ltd. and Farmarc Netherlands B.V. (Registration No. 2807216),
will be approximately $44.9 million, or approximately $51.9 million if the
underwriters fully exercise their over-allotment option, in each case assuming
an initial public offering price of $9.00 per share and after deducting the
estimated underwriting discount and estimated offering expenses payable by us.

   The principal purposes of this offering are to increase funds available for:

   o research and development activities, including clinical trials, which we
     estimate could approximate $35.0 million,

   o milestone and other payments payable under our strategic agreements,
     including a minimum of $1.0 million and a maximum of $2.0 million in the
     aggregate payable to Shimoda and Farmarc upon the closing of this
     offering, which payment will be $1.0 million assuming an initial public
     offering price of $9.00 per share,

   o working capital, and

   o other general corporate purposes.

   The amount and timing of our actual expenditures will depend on numerous
factors, including the progress of our research and development activities and
clinical trials, the number and breadth of our product development programs,
our ability to establish and maintain corporate collaborations and other
arrangements and the amount of cash, if any, generated by our operations. In
addition, a portion of the net proceeds may be used for the acquisition of
businesses, products and technologies that are complementary to our own. We
are not currently engaged in any negotiations to acquire any other company. We
will retain broad discretion in the allocation and use of the net proceeds of
this offering. Pending application of the net proceeds as described above, we
intend to invest the remaining net proceeds from this offering in short-term,
investment-grade, interest-bearing securities.

                                DIVIDEND POLICY

   We have never declared nor paid any cash dividends on our common stock. We
do not intend to pay cash dividends on our common stock in the foreseeable
future. We presently intend to retain future earnings, if any, to finance the
expansion and growth of our business. Any future determination to pay
dividends will be at the discretion of our board of directors and will depend
on our financial condition, results of operations, capital requirements and
other factors that our board of directors deems relevant.


                                       19

                                 CAPITALIZATION

   The following table describes our capitalization as of December 31, 2001:

   o on an actual basis,

   o on a pro forma basis to give effect to the automatic conversion, on
     approximately a 1.0161-for-one basis, of 5,004,116 shares of our

                                    DILUTION


   The historical net tangible book value (deficit) as of December 31, 2001 was
approximately $(11.9) million, or $(1.20) per share of common stock.
Historical net tangible book value (deficit) represents the amount of our
total assets less the aggregate of prepaid offering costs, convertible
preferred stock and total liabilities. Historical net tangible book value
(deficit) per share represents historical net tangible book value (deficit)
divided by the number of shares of our common stock outstanding at December
31, 2001. The pro forma net tangible book value as of December 31, 2001 was
approximately $6.9 million, or $0.46 per share of common stock. Pro forma net
tangible book value represents the amount of our historical net tangible book
(deficit) adjusted to give effect to the conversion of all shares of series A
and series B convertible preferred stock into an aggregate of 5,084,900 shares
of common stock, which will occur upon the closing of this offering. After
giving effect to the issuance and sale by us of the shares of common stock
offered by this prospectus at an assumed initial public offering price of
$9.00 per share and after deducting the estimated underwriting discount and
estimated offering expenses and an estimated payment by us of $1.0 million due
to Shimoda and Farmarc upon completion of this offering in connection with a
licensing agreement, our pro forma as adjusted net tangible book value as of
December 31, 2001 would have been approximately $51.5 million, or
approximately $2.50 per share. This represents an immediate increase in the
historical net tangible book value of $2.04 per share to existing stockholders
and immediate dilution of $6.50 per share to new investors participating in
this offering, which is illustrated by the following table:

   Assuming the exercise in full of the underwriters' over-allotment option,
our pro forma as adjusted net tangible book value as of December 31, 2001
would have been approximately $58.5 million, or approximately $2.72 per share.
This represents an immediate increase in the historical net tangible book
value (deficit) of $3.92 per share to existing stockholders and immediate
dilution of $6.28 per share to new investors participating in this offering.

   The following table sets forth, on a pro forma as adjusted basis as of

   The foregoing discussion and tables assume no exercise of any stock options
or warrants and no issuance of shares reserved for future issuance under our
equity plans. As of December 31, 2001, there were 9,960,427 shares
outstanding, which excludes:

dilutive to investors in this offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


   You should read the following discussion in conjunction with our financial
statements, the related notes and other financial information appearing
elsewhere in this prospectus. This discussion may contain forward-looking
statements based upon current expectations that involve risks and
uncertainties. Our actual results and the timing of selected events could
differ materially from those anticipated in these forward-looking statements
as a result of many factors, including those set forth under "Risk Factors"
and elsewhere in this prospectus.

Overview

   We have devoted substantially all of our resources since we began our
operations in February 1998 to the development of proprietary pharmaceutical
products for the treatment of pain. We are a development stage pharmaceutical
company and have not generated any revenues from product sales. We have not
been profitable and, since our inception, we have incurred an accumulated net
loss attributable to our common stockholders of approximately $36.3 million
through December 31, 2001. These losses have resulted principally from costs
incurred in research and development activities, including acquisition of
technology rights and general and administrative expenses. We expect to incur
additional operating losses until such time as we generate sufficient revenue
to offset expenses and may never achieve profitable operations.

   Research and development, manufacturing and marketing costs will continue to
increase as we advance our product candidates and prepare for the
commercialization of our products pending regulatory approval.


   Since our inception, we have incurred approximately $29.7 million of
research and development costs. The major research projects undertaken by us
include intranasal ketamine, morphine and fentanyl. Total research and
development costs incurred to date for each of these products was
approximately $3.1 million, $6.6 million and $0.8 million, respectively.
We have also recently commenced research on a new product candidate,
intravenous diclofenac. In addition, there was approximately $0.6 million of
research and development costs incurred since inception which do not relate to
our major research projects and we incurred a charge of approximately
$18.6 million related to our merger with Pain Management, Inc. and the
acquisition of a licensing agreement. For various reasons, many of which are
outside our control, including timing and results of our clinical trials,
obtaining regulatory approval and dependence on third parties, we cannot
estimate the total remaining costs to be incurred to commercialize our
products, nor is it possible to estimate when, if ever, any of our products
will be approved by regulatory agencies for commercial sale. In addition, we
may experience adverse results in the development of our products, which could
result in significant delays in obtaining approval to sell our products,
additional costs to be incurred to obtain regulatory approval or failure to
obtain regulatory approval. In the event any of our product candidates were to
experience setbacks, it would have a material adverse effect on our financial
position and operating results. Even if we successfully complete developments
and obtain regulatory approval of one or more of our products, failure of
physicians and patients to accept our products as a safe, cost-effective
alternative compared to existing products would have a material adverse effect
on our business.


   In June 2000, we issued 5,080,717 shares of our common stock to our
founders. In September 2000, in connection with our merger with Pain
Management, Inc., we issued an aggregate of 4,648,220 shares of our common
stock for the outstanding shares of Pain Management's common stock. At the
time of the merger, the only asset held by us was a license agreement with
West Pharmaceutical Services, Inc. We remained dormant until the merger and
the execution of the license agreement. The merger was accounted for financial
reporting purposes as the acquisition of a license agreement by the
predecessor company and a reorganization with Innovative Drug Delivery
Systems, Inc. as the surviving entity. As a result, our assets, liabilities
and historic operating results prior to September 2000 are those of Pain
Management. The fair value of the license agreement was determined to be
approximately $18.6 million based on the then fair value of the common stock
we issued. Since the licensed technology had not reached technological
feasibility and had no alternative future use, the fair value of the
consideration issued to obtain the license agreement was expensed as research
and development at the time the merger closed.


                                       25


   As of December 31, 2001, if certain defined events occur, we would be
required to pay West Pharmaceutical in the future an aggregate of $11.25
million for research and development milestones, which include the filing of
an NDA with the FDA for intranasal morphine, the approval of an NDA by the FDA
and the first commercial sale of a licensed product. As of December 31, 2001,
we had paid West $5.4 million in cash. The timing of the remaining milestones
is dependent upon factors that are beyond our control, including our ability
to recruit patients, the outcome of future clinical trials and any
requirements imposed on our clinical trials by the FDA. If the FDA imposes
more stringent requirements on our clinical trials, the length and number of
such trials may be increased resulting in additional research and development
expenses.

   In addition, under the license agreement with Shimoda Biotech (Proprietary)
Ltd., we are obligated to pay a license fee of $1.5 million to Shimoda, of
which $550,000 was paid as of December 31, 2001. In addition, following
completion of this offering, we are obligated to pay Shimoda and Farmarc
Netherlands B.V. (Registration No. 2807216) an aggregate of 2% of the net
proceeds from this offering, subject to a minimum payment of $1.0 million and
a maximum payment of $2.0 million. Under this agreement, we are also obligated
to pay to Shimoda an aggregate of $6.0 million upon the occurrence of
specified developmental milestones, which include the filing of an NDA with
the FDA for diclofenac, the approval of an NDA by the FDA and the first
commercial sale of a licensed product and pay a royalty based upon our and our
sublicensees' sales of products. The timing of the remaining milestones is
dependent upon factors that are beyond our control, including our ability to
recruit patients, the outcome of future clinical trials and any requirements
imposed on our clinical trials by the FDA. If the FDA imposes more stringent
requirements on our clinical trials, the length and number of such trials may
be increased resulting in additional research and development expenses.


   In addition, under the license agreement with Dr. Weg, we are obligated to
make aggregate milestone payments of approximately $1.6 million, of which
$300,000 was paid as of December 31, 2001, upon the earlier of certain defined
dates ranging from August 2003 to November 2004 or satisfaction of certain
clinical and regulatory milestones, which include the filing of an NDA with
the FDA for ketamine, the approval of an NDA by the FDA and the first
commercial sale of a licensed product. The timing of the remaining milestones,
which total approximately $1.3 million, is dependent upon factors that are
beyond our control, including our ability to recruit patients, the outcome of
future clinical trials and any requirements imposed on our clinical trials by
the FDA. If the FDA imposes more stringent requirements on our clinical
trials, the length and number of such trials may be increased resulting in
additional research and development expenses.

Non-Cash Expense, Beneficial Conversion Feature and Financial Support Provided
by a Principal Stockholder


   Since our inception, we have issued stock or granted stock options or
warrants to non-employee lenders and consultants for which we recorded non-
cash expense of approximately $93,000 in 1999 and $708,000 in 2000.


   In December 2001, we issued 989,991 shares of series B preferred stock in
consideration of gross proceeds of approximately $5.5 million. The series B
conversion price represented a discount from the estimated fair value of our
common stock at the time of issuance. Accordingly, the discount amount is
considered incremental yield to the preferred stockholders and has been
accounted for as a deemed dividend to preferred stockholders. Based on the
conversion terms of the series B stock, a deemed dividend of approximately
$3.6 million has been added to the net loss applicable to common stockholders
in the year ended December 31, 2001.

   Since our inception, Paramount Capital Investments, LLC has provided us with
office space, industry expertise, financial support and certain administrative
and legal assistance at no cost to us. Paramount Capital Investments is an
affiliate of Paramount Capital, Inc., which, in turn, is affiliated with one
of our principal stockholders. Paramount Capital is an integrated, privately
held, full-service investment banking firm specializing in private placements
of equity and debt securities for publicly traded and privately held
biotechnology and biopharmaceutical companies. Paramount's assistance has
allowed us to focus our available cash resources almost exclusively on product
development and has reduced our cash burn rate through in-kind overhead
contributions.


                                       26

   The estimated fair value of Paramount's assistance has been reflected in the
accompanying financial statements as an expense in the period benefited with a
corresponding deemed capital contribution. The estimated fair value of the
financial assistance totaled $89,531 for the period from February 23, 1998
(inception) to December 31, 1998, $155,917 for the year ended December 31,
1999, $163,376 for the year ended December 31, 2000 and $481,299 for the year
ended December 31, 2001.

Results of Operations

   Revenues.  With the exception of revenues derived from government grants, we
have generated no operating revenues since our inception and do not expect
operating revenues for the foreseeable future. In the second half of 2000, we
were awarded a $1.2 million research and development grant for intranasal
ketamine from the Department of Defense, or DOD, payable monthly from October
1, 2000 to October 31, 2003. Also in 2000, we were awarded a $298,000 research
and development grant from the National Institutes of Health, or NIH, for
intranasal ketamine. The DOD and NIH grants are billed monthly as costs are
incurred.

   Research and Development Expenses.  Research and development expenses
consist primarily of salaries and related expenses for personnel, materials
and supplies used to develop our product candidates. Other research and
development expenses include compensation paid to consultants and outside
service providers and the costs to license acquired technologies that have no
alternative future use. We expense research and development costs as incurred.
We expect that we will continue to incur significant research and development
expenses in the future.

   General and Administrative Expenses.  General and administrative expenses
consist primarily of salaries and other related costs for personnel in
executive, finance, accounting, information technology and human resource
functions. Other costs include facility costs and professional fees for legal
and accounting services.

   Interest Income and Expense.  Interest income consists of interest earned on
our cash and cash equivalent balances. Interest expense consists of interest
incurred on loans.

Years Ended December 31, 2000 and 2001

   Revenues.  Grant revenue increased from $306,035 for the year ended December
31, 2000 to $882,358 for the year ended December 31, 2001. The increase is
attributable to grant revenue resulting from an increase in resources
dedicated to fulfilling our obligations under the DOD and NIH grants.

   Research and Development Expenses.  Research and development expenses
decreased from approximately $21.8 million for the year ended December 31,
2000 to approximately $7.0 million for the year ended December 31, 2001. The
decrease in research and development expense resulted primarily from an $18.6
million noncash charge we recorded for the year ended December 31, 2000 for
the fair value of the license agreement purchased in connection with the
merger with Pain Management. Excluding the non-cash charge, research and
development expenses increased from approximately $3.2 million for the year
ended December 31, 2000 to $7.0 million for the year ended December 31, 2001.

   This increase resulted from increased costs associated with the clinical
development of our lead product candidates, intranasal ketamine and intranasal
morphine. Four human clinical trials were active during the period, including
two intranasal ketamine Phase II clinical trials and two intranasal morphine
Phase I clinical trials. Our consulting expenses also increased as a result of
increased clinical activity associated with protocol development, regulatory
management and report finalization.

   General and Administrative Expenses.  General and administrative expenses
increased from approximately $1.4 million for the year ended December 31, 2000
to approximately $2.3 million for the year ended December 31, 2001. This
increase resulted from the hiring of additional personnel and increased
professional service fees. We expect general and administrative expenses to
increase further as we hire additional personnel, lease our own facilities and
separate our operations from Paramount.

   Interest Expense.  Interest expense decreased from $320,533 for the year
ended December 31, 2000 to zero for the year ended December 31, 2001. The
decrease in interest expense was due to the repayment of


                                       27

$475,000 of bank notes and $1.0 million of bridge notes during 2000 from the
net proceeds of our September 2000 series A convertible preferred stock
financing. We had no debt outstanding during 2001.

   Interest Income.  Interest income increased from $177,490 for the year ended
December 31, 2000 to $348,475 for the year ended December 31, 2001. The
increase in interest income was primarily due to interest earned on the net
proceeds raised from our September 2000 series A convertible preferred stock
financing.

The Period from February 23, 1998 (inception) to December 31, 1998 and the
Years Ended
December 31, 1999 and 2000

   Revenues.  We generated no operating revenues during 1998 and 1999. We
generated revenues of $306,035 in 2000 due to the commencement of projects
funded by grants from the DOD in July 2000 and the NIH in September 2000.

   Research and Development Expenses.  Research and development expenses
increased from $206,618 in 1998 to $664,636 in 1999 and to $21.8 million in
2000. The increase in research and development expense from 1998 to 1999
resulted primarily from the license fee paid to West Pharmaceutical for
entering into a license agreement for intranasal morphine and subsequent costs
associated with initiation of the intranasal morphine development program. The
increase in research and development expenses from 1999 to 2000 resulted
primarily from costs associated with acquisition of a license agreement valued
at approximately $18.6 million in connection with the merger with Pain
Management.

   General and Administrative Expenses.  General and administrative expenses
increased from $256,980 in 1998 to $312,079 in 1999 and increased to $1.4
million in 2000. The increase in general and administrative expenses resulted
primarily from the hiring of additional personnel, including senior level
management, and costs associated with business development, consulting
services related to market research, fundraising and travel. The increase in
general and administrative expenses from 1998 to 1999 was due to the hiring of
additional personnel. The increase in general and administrative expenses from
1999 to 2000 resulted primarily from non-cash compensation expenses of
approximately $708,000 relating to options granted to non-employees and from
an increase in the number of personnel from three employees in the first
quarter of 1999 to seven employees in the fourth quarter of 2000 and related
expenses necessary to support our growth.

   Interest Expense.  Interest expense increased from $6,602 in 1998 to
$239,092 in 1999 and $320,533 in 2000. The increase in interest expense from
1998 to 1999 and from 1999 to 2000 resulted from interest accrued on the
bridge notes. Between April 1999 and July 2000, the bridge notes accrued
interest at a rate of 12% per annum for the first 12 months and 15% per annum
thereafter.

   Interest Income.  Interest income increased from zero in 1998 to $10,572 in
1999 and $177,490 in 2000. The increase in interest income from 1998 to 1999
reflected interest earned from proceeds raised from $1.0 million of our bridge
notes issued from April through July 1999. The increase in interest income
from 1999 to 2000 reflected higher invested balances during 2000 due primarily
to interest earned on the proceeds of our September 2000 series A convertible
preferred stock financing.

Liquidity and Capital Resources

   As of December 31, 2001, we had cash and cash equivalents of approximately
$7.7 million, and working capital was approximately $6.8 million.

   From inception through December 31, 2001, net cash used in operating
activities was approximately $11.2 million. From inception through December
31, 2001, net cash used in investing activities was $75,702, primarily due to
the acquisition of products, furniture and fixtures and office equipment, and
the purchase of short-term investments. From inception through December 31,
2001, net cash provided by financing activities was $19.0 million. The
principal source of cash was from equity and debt financings.

   We expect that our operating expenses and capital expenditures will increase
in future periods as a result of increased preclinical studies and clinical
trial activity, research and development and the anticipated


                                       28

commercialization of our product candidates, assuming we receive the necessary
regulatory approvals. The initiation of commercial activities will require the
hiring of additional staff to coordinate contract manufacturing services at
multiple locations. Research and development expenditures, including clinical
trials, are expected to increase as we continue to develop new product
candidates.

   We also intend to hire additional research and development, clinical and
administrative staff. Our capital expenditure requirements will depend on
numerous factors, including the progress of our research and development
programs, the time required to file and process regulatory approval
applications, the ability to obtain additional licensing arrangements, and the
demand for our product candidates, if and when approved by the FDA or other
regulatory authorities. Our expenditures would also increase if we are
required to pay Paramount or other third parties for administrative and other
costs, including rent.


   In the event we achieve any of our milestones relating to morphine
or fentanyl before March 31, 2003, our aggregate obligations under our
agreements with West Pharmaceutical would be $2.5 million for morphine and $1.5
million for fentanyl. With respect to ketamine, we are also obligated to make
aggregate payments before March 31, 2003 to Dr. Weg of $750,000. Based upon the
timing of our trials and the FDA review process, we do not anticipate any other
significant capital commitments relating to our license and development
agreements in the next twelve months.


   We believe that our current cash and investment position will be sufficient
to fund our operations and capital expenditures at least through the next 12
months.

Income Taxes

   As of December 31, 2001, we had approximately $12.6 million of net operating
loss carryforwards available to offset future taxable income. These
carryforwards will begin to expire in 2018.

Recent Accounting Pronouncements

   In July 2001, the Financial Accounting Standards Board issued Statement No.
141, "Business Combinations," and Statement No. 142, "Goodwill and Other
Intangible Assets." FAS 141 requires that all business combinations be
accounted for under the purchase method and that certain acquired intangible
assets in a business combination be recognized as assets apart from goodwill.
FAS 142 requires that ratable amortization of goodwill and certain intangible
assets be replaced with periodic tests of the goodwill's impairment and that
other intangible assets be amortized over their useful lives. FAS 141 is
effective for all business combinations initiated after June 30, 2001. The
provisions of FAS 142 will be effective for fiscal years beginning after
December 15, 2001 and will be adopted by us in 2002. We do not expect the
adoption of FAS 141 or 142 to have any material impact on our financial
statements.


   In July 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143, "Accounting for Obligations Associated
with the Retirement of Long-Lived Assets." The objective of FAS 143 is to
provide accounting guidance for legal obligations associated with the
retirement of tangible long-lived assets. The retirement obligations included
within the scope of FAS 143 are those that an entity cannot avoid as a result
of either the acquisition, construction or normal operation of a long-lived
asset. Components of larger systems also fall under FAS 143, as well as
tangible long-lived assets with indeterminable lives. FAS 143 is required to
be adopted on January 1, 2003. We do not expect the adoption of FAS 143 to
have any material impact on our financial statements.

   In August 2001, the Financial Accounting Standards Board issued FASB
Statement No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets." The objectives of FAS 144 are to address significant issues relating
to the implementation of FASB Statement No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
and to develop a single accounting model, based on the framework established
in FAS 121, for long-lived assets to be disposed of by sale, whether
previously held and used or newly acquired. The provisions of FAS 144 are
effective for financial statements issued for fiscal years beginning after
December 15, 2001. We do not expect the adoption of FAS 144 to have any
material impact on our financial statements.



                                       29

Disclosure About Market Risk

   Our exposure to market risk is principally confined to our cash equivalents,
all of which currently have maturities of less than three months. We maintain
a non-trading investment portfolio of investment grade, liquid debt securities
that limits the amount of credit exposure to any one issue, issuer or type of
instrument. The fair value of these securities approximates their cost.

   The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from investments
without significantly increasing risk. Some of the securities that we may
invest in may be subject to market risk. This means that a change in
prevailing interest rates may cause the value of the investment to fluctuate.
For example, if we purchase a security that was issued with a fixed interest
rate and the prevailing interest rate later rises, the value of our investment
will probably decline. To minimize this risk, we intend to maintain our
portfolio of cash equivalents and short-term investments in a variety of
securities, including commercial paper, money market funds and government and
non-government debt securities. In general, money market funds are not subject
to market risk because the interest paid on such funds fluctuates with the
prevailing interest rate. As of December 31, 2001, we neither had any holding
of derivative financial or commodity instruments, nor any foreign currency
denominated transactions, and all of our cash and cash equivalents were in
money market and checking funds.

                                    BUSINESS


   We are a specialty pharmaceutical company that applies proprietary
technologies to develop new drugs and improved formulations of existing drugs
for the prescription pain management market. We believe that our product
candidates address unmet medical needs for breakthrough cancer pain,
postoperative pain, lower-back pain, pain due to orthopedic injury, dental
pain and pain due to other indications. We believe our product candidates
offer a combination of enhanced pain relief, improved side effect profiles and
faster onset of pain relief compared to currently available treatments.

   Pain is an unpleasant sensory and emotional experience. The sensation of
pain can be caused by actual or potential tissue damage, such as that
resulting from an injury or trauma, or may be the result of a disease.

Classifications of Pain

   How an individual feels pain is a complicated process that is carried out by
the central nervous system. Each individual's perception of pain is a
subjective and personal experience. In order to prescribe the appropriate
medications for treatment, clinicians evaluate pain according to duration,
intensity and cause. Duration describes the period of time over which pain
impacts a patient's life before it is resolved. The intensity of pain directly
impacts a patient's ability to perform routine, everyday activities, ranging
from daily work to self-care. The cause of pain is linked to its underlying
origin, whether it be the consequence of direct injury or an inflammatory
process. The overall experience of pain is a combination of these three
factors. Clinicians consider each of these factors, individually and
collectively, when developing the therapeutic regimen most effective for
patients.

Pain Categories

   The duration of pain can be categorized as either acute or chronic depending
on its origin.

   Acute pain is typically brief in duration and eases of its own accord or
after successful treatment of the underlying problem. Acute pain usually
results from trauma or surgery.

   Episodic flare-ups of acute pain occurring on a background of treated,
persistent pain may complicate chronic pain. These flare-ups are referred to
as "breakthrough pain" and may be frequent and unpredictable.

   Chronic pain persists or recurs for prolonged periods and may last for a
patient's lifetime despite the healing process. Some of the more common types
of chronic pain are associated with cancer and other long-term conditions,
including lower-back pain.

Pain Intensity

   The intensity of pain can be described as mild, moderate or severe.

   Mild pain generally does not affect the routines of daily life. Common
examples of mild pain include muscular aches and mild headaches. Mild pain
almost always responds to over-the-counter medications such as NSAIDs,
including aspirin and acetaminophen.

   Moderate pain can affect an individual's daily life and can be debilitating.
Common examples of moderate pain include pain from minor surgery or orthopedic
injury. Such pain may require treatment with prescription pain medicines,
typified by opioids, including morphine, and stronger NSAIDs, including
ketorolac.

   Severe pain drastically interferes with even the simplest daily activities
and undermines an individual's quality of life. Common examples of severe pain
include pain resulting from serious underlying conditions, including cancer,
major surgery or trauma. Treatment of severe pain requires the most potent
medications, typically prescription opioid narcotics, including morphine and
fentanyl, at very high doses.


                                       31

Causes of Pain

   The causes of pain are classified as somatic, visceral and neuropathic. Each
of these causes is differentiated by the tissue affected.

   Somatic pain results from injuries to skin, muscle, bone, or joint and is
typically characterized as a sharp pain that is localized to an injured area.
Somatic pain may be mild, moderate or severe in intensity, depending on the
extent of the injury.

   Visceral pain is produced by injury, inflammation or stretching of internal
organs and is typically characterized by diffuse, poorly localized, dull and
vague pain. Visceral pain is usually moderate-to-severe in intensity, such as
abdominal pain accompanying appendicitis or the passing of a kidney stone.

   Neuropathic pain is produced by injuries or inflammation of nerves and is
typically characterized by diffuse, burning pain. Cancer pain is one of the
most common examples of neuropathic pain.

   The following table gives examples of how common indications of pain can be
described using the classifications set forth above:

Pain Management Market

   Pain is a serious health and economic problem. According to Front Line
Strategic Management Consulting, Inc., the worldwide market for therapeutics
to manage pain is expected to grow from $22 billion in 2000 to $30 billion in
2007. Over the past ten years, the healthcare industry has taken active
measures that focus on the importance of pain management as a component of
patient care. These measures include:

   o The designation of pain management as a recognized subspecialty for
     physicians by the American Board of Medical Specialties in 1991.

   o The 1994 publication by the Agency for Health Care Policy and Research,
     U.S. Department of Health and Human Services, or AHCPR, of guidelines for
     the treatment of breakthrough cancer pain recommending the administration
     of regularly scheduled analgesic doses as well as additional doses of
     breakthrough pain medication.

   o The requirement, as of 1999, for all U.S. hospitals and healthcare
     facilities to assess the adequacy of pain treatment for each patient on a
     regular basis in order to achieve accreditation by the Joint Commission
     on Accreditation of Healthcare Organizations.

   o The recommendation by the World Health Organization to increase the
     availability of opioids in order to meet demand for treatment of patients
     in pain.


                                       32

Because of the increasing awareness of the importance of pain management by
the healthcare industry, growth in the pain management market has been
significant in recent years and is expected to continue. Additional factors
that are contributing to the growth of the pain management market include:

   o population demographic shifts growing the target market population,

   o new therapies that have increased survival times for patients with
     chronic conditions,

   o increasing recognition of the therapeutic and economic benefits of
     effective pain management by physicians, healthcare providers and payors,

   o rapid market acceptance of new products with novel mechanisms of action,
     and

   o targeted markets that permit cost-effective selling and marketing.

   Left unmanaged, pain can significantly compromise an individual's quality of
life. Drugs are a key element in the treatment of pain. The drugs most
commonly used to treat acute, moderate-to-severe pain include strong opioids,
such as morphine, and in the case of moderate pain, weaker opioids such as
hydrocodone and oxycodone or stronger NSAIDs, such as ketorolac. Patients
suffering from chronic, moderate-to-severe pain syndromes, such as cancer
pain, often require long-term use of opioids that are typically prescribed in
sustained- or extended-release formulations. Chronic pain is often treated
with a combination of drugs, including sustained-release products, such as the
fentanyl patch or sustained-release morphine, to treat the underlying baseline
pain and immediate-release products, such as transmucosal fentanyl, or
immediate release or intravenous morphine to treat episodic breakthrough pain.

   Based on information from The Analytica Group, the table below shows the
total predicted market for several key pain indications, in order of total
annual market size, that we believe our product candidates will address. These
market projections are based on the estimated U.S. presenting population, which
is the subset of the total population that seeks medical attention for the
respective indication, for the year 2000. The cost of therapy for each
indication is calculated by multiplying the estimated average daily cost of
prescription pain medication for our product candidates by the number of therapy
days. The total market for each indication is calculated by multiplying the U.S.
presenting population by the cost of therapy.

   Breakthrough Cancer Pain

   The 2000 U.S. incidence rate of breakthrough cancer pain as determined by
The Analytica Group and the American Cancer Society was estimated to be
approximately 793,000 patients per year. It is estimated that more than 70% of
cancer patients with advanced disease suffer from moderate-to-severe
breakthrough pain and are treated for their conditions with a combination of
short and long acting analgesics. On average, patients suffering from
breakthrough pain experience three to four breakthrough episodes per day and
require therapy for their condition for an average of 150 days per year. The
current standard of care for breakthrough pain is the administration of as-
needed, immediate-release oral opioids.

   Most patients with advanced cancer experience pain, and one out of five of
such patients experience uncontrolled pain. The World Health Organization has
established guidelines that recommend the appropriate medications that
physicians should prescribe for the management of cancer pain. However, these
guidelines do not address the limited treatment options available for patients
who have uncontrolled, or breakthrough, pain.


                                       33

   Breakthrough cancer pain is characterized by acute episodes of chronic
moderate-to-severe, neuropathic pain that suddenly flares-up and does not
respond to standard pain management treatments. This type of pain is
particularly difficult to treat due to its severity, rapid onset and the
unpredictable nature of its occurrence. Breakthrough pain may be further
classified into three types: incident pain, spontaneous pain or pain occurring
when the background pain management medication reaches the limits of its
effectiveness. This latter type of breakthrough pain is also referred to as
end of dose failure. Incident pain is usually precipitated by a voluntary
action, such as movement. By comparison, an episode of breakthrough pain that
is spontaneous in its origin is not associated with a precipitating event.
Breakthrough pain associated with end of dose failure occurs more frequently
near the end of a dosing interval for the standard pain management drug that
the patient is using to control background pain.

   We believe that our product candidates, if approved, will provide an
effective, alternative treatment for breakthrough pain.

   Postoperative Pain

   Postoperative pain is typically attributable to acute, mild-to-severe pain,
can be somatic, visceral or neuropathic in cause, and is the direct result of
a surgical procedure.

   The need for postoperative pain management depends in large part on the
magnitude of the surgical trauma. Generally, the greater the magnitude of the
surgery, the greater the postoperative discomfort. The choice of analgesic can
be based on the invasiveness of the surgical procedure. Minor surgical
procedures such as arthroscopy and breast biopsy are minimally invasive and
produce minimal surgical trauma. These types of procedures are usually
performed on an out-patient basis. Postoperative pain following minor surgical
procedures is usually provided with oral or parenteral NSAIDs or a weak oral
opioid for the management of breakthrough pain episodes.

   More invasive surgical procedures of an intermediate nature, such as
hysterectomy, appendectomy and total joint replacement, require
hospitalization for the management of postoperative pain. Intravenous patient-
controlled analgesia, or PCA, with opioids is the therapy of choice for
treating this patient population prior to discharge from the hospital. PCA
allows a patient to receive drugs on demand by using an infusion pump that is
programmed by the physician to intermittently administer drugs when the
patient pushes a button. The addition of parenteral or oral NSAIDs to this
regimen is gaining broader use as these have been demonstrated to decrease the
requirement for opioids.

   Major surgery, such as heart surgery, produces major trauma and requires
hospitalization. Treatment of postoperative pain following major surgery often
requires epidural infusion of the strongest opioids supplemented by PCA with
opioids and oral or parenteral NSAIDs to manage breakthrough pain episodes.

   We believe our product candidates will be effective for the management of
pain following minor surgical procedures, offer a readily acceptable
alternative to intravenous PCA for the management of moderate-to-severe
postoperative pain following intermediate procedures, and have utility for the
treatment of breakthrough pain associated with major surgical procedures.

   Lower-Back Pain

   Lower-back pain is the most common medical complaint in developed countries.
As a result, the patient population is extremely large. Our product candidates
are designed for individuals whose lower-back pain is severe enough to limit
their activities. According to the Centers for Disease Control, in 1998 there
were approximately 7.9 million individuals whose chronic back problems were
activity limiting.

   Lower-back pain is typically acute, mild-to-severe, somatic pain, although a
substantial percentage of sufferers develop chronic symptoms. Episodes of
breakthrough lower-back pain are treated with both over-the-counter and
prescription medications, depending on the severity of symptoms. The most
severe episodes may require the use of opioids.

   We believe that our product candidates, if approved, will provide an
effective, alternative treatment for patients experiencing breakthrough lower-
back pain.


                                       34

   Orthopedic Injury

   Orthopedic injuries are associated with acute, somatic pain that varies in
intensity from mild to severe depending on the extent of the trauma. Those
injuries that are the result of a fracture or dislocation are usually
associated with mild-to-severe pain. Many patients with fractures or
dislocations are treated by an orthopedist in the emergency department of a
hospital or clinic and are discharged the same day.

   Treatment of fractures can involve the realignment of bones, a procedure
referred to as reduction. Although fractures and dislocations are generally
due to minor injuries, the time leading up to and during reduction of a
fracture or the correction of a dislocation is often associated with acute,
moderate-to-severe, somatic pain. Pain due to orthopedic injury is generally
under-treated or untreated in the emergency department.

   Our product candidates may be effective in treating pain associated with
procedures that are the result of orthopedic injury, such as pin removal. Pin
removal is a painful process that follows certain types of setting procedures
that require external fixtures. In these types of surgical procedures, pins
are placed into the broken bone above and below the fracture site in order to
allow the orthopedic surgeon to reposition the bone fragments. The pins may
subsequently be connected to an external frame that immobilizes the bone and
is kept in place until the fracture heals. Analgesia is often necessary at the
time of removal of this external stabilizing device.

   We believe that emergency departments have an economic incentive to use any
therapy that can speed patient discharge from the hospital and avoid expenses
associated with administration of intravenous drugs. We also believe that our
product candidates satisfy the unmet medical need for agents that are fast
acting, safe and easily titrated to treat moderate-to-severe pain associated
with orthopedic injury in the emergency department setting.

   Dental Pain

   The 2000 U.S. incidence rate of dental pain as determined by The Analytica
Group was estimated to be approximately 21.6 million patients per year. Dental
pain is typically acute, mild-to-severe, somatic pain. Dental pain associated
with oral surgery, including wisdom tooth extraction and periodontal
procedures, frequently requires short-term management with opioid analgesics
or strong NSAIDs.

   The treatment of dental pain with analgesics is complicated by the inherent
difficulties in swallowing following dental surgery and the unusual intensity
of its symptoms. Pain originating in the tooth pulp or surrounding gums is
instantly worsened by even the slightest changes in temperature, humidity or
pressure and, as a result, dental pain has been described as excruciating.
Relief from pain of this quality requires substantial doses of the strongest
opioids.

   We believe our product candidates will provide an effective, rapidly acting,
non-oral alternative for the treatment of pain resulting from oral surgery.

Limitations of Current Pain Management

   Despite advances in medicine and the development of new drugs, we believe
pain management remains a critical area of unmet medical need. Increasingly,
patients, advocacy groups and the media are highlighting the shortcomings of
pain management and are demanding changes to the current standards of care
provided by the medical system. To address these inadequacies, clinicians and
the pharmaceutical industry are creating a variety of different pain control
products that can provide the flexibility and versatility required to close
the gap in the current practice of pain management. These gaps include:

   o Slow onset of action.  Commercially available oral pain medications can
     take 20 to 40 minutes to provide detectable levels of pain relief. Drugs
     delivered through a transdermal patch can take several hours to reach
     effective blood levels, and prolonged drug absorption can occur after
     patch removal.

   o Insufficient dose-to-intensity control.  It is difficult to match the
     doses of drugs that are administered orally or by transdermal patch to
     the patient's level of pain. This mismatch can result in either under-
     treatment or over-treatment.


                                       35

   o Costly to administer.  Although intravenous administration provides rapid
     entry of drugs into the bloodstream, delivery by this route requires both
     trained personnel and, in some cases, specialized equipment. This adds to
     the overall cost of therapy.

   o Invasive route of delivery.  Intravenous or intramuscular delivery of
     drugs can cause pain to patients when administered. Consequently, some
     patients are adverse to receiving injections.

   o Poor side-effect profile.  Opioids, such as morphine, are associated with
     a number of side effects, including nausea, vomiting, constipation,
     respiratory depression and sedation. In addition, some patients are
     unable to use opioid medications.

Our Solution

   We believe that our product candidates, if approved, address many of the
limitations of existing pain treatment therapies by providing one or all of
the following characteristics:

   o Rapid onset of pain relief.  Our intranasal ketamine and morphine product
     candidates rapidly enter the bloodstream following administration and
     generally provide detectable pain relief within two to five minutes after
     administration.

   o Appropriate dose-to-intensity control.  Our intranasal product candidates
     allow the patient to administer an amount of drug that is appropriate for
     that individual's level of pain and to discontinue administration once a
     desired level of pain relief is obtained. This ability to self-regulate
     the dose of drugs avoids doses that are higher than necessary to achieve
     safe and effective management of pain.

   o Low cost to administer.  Our intranasal product candidates permit patients
     to self-administer and self-regulate the dose of drugs. This eliminates
     the need for the personnel and equipment necessary to establish an
     intravenous line and is more affordable for hospitals and home care
     settings.

   o Non-invasive route of delivery.  Our intranasal product candidates are
     non-invasive, eliminating the need for injections. In addition, a non-
     invasive route of delivery reduces the incidence of needle stick injuries
     and the potential for transmission of blood-borne viruses.

   o Improved side-effect profile.  Our intranasal ketamine and intravenous
     diclofenac product candidates have improved side-effect profiles over
     comparable products in their category. For example, they are non-sedating
     and do not affect a patient's blood pressure or heart rate. In addition,
     when used in combination with other opioids, ketamine and diclofenac have
     been reported to reduce the amount of opioids required to produce an
     equal level of pain relief, which reduces the requirement for narcotics.
     This reduction in the requirement for opioids can enhance the patient's
     overall quality of life.

Product Candidates


   Our product candidates are comprised of a number of well-known analgesic
drugs that, in combination with our chosen routes of administration, are under
development for the treatment of a variety of acute and chronic moderate-to-
severe pain syndromes. We selected our product candidates for development
based on our belief that they offer significantly lower clinical, regulatory
and commercial risk profiles as compared to new chemical entities.


   We are evaluating each of our product candidates in several clinical models
of pain in order to seek approval by the FDA for use in the treatment of acute
and chronic moderate-to-severe pain indications. The guidelines established by
the FDA recommend that we demonstrate effectiveness in more than one clinical
model of pain. Acceptable clinical models of pain include dental pain,
postoperative pain, cancer pain and pain due to various types of trauma.
Typically, our clinical trials are designed as randomized, double-blind,
placebo-controlled and, where appropriate, comparator-controlled studies. A
randomized study is one in which the patient is randomly assigned to receive a
study drug or placebo based on a pre-determined ratio. A double-blind study is
one in which the patient, the physician and the sponsor are unaware if the
patient is receiving a placebo or drug in order to preserve the integrity of
the trial and prevent observer bias. A placebo-controlled study is one in
which a subset of patients is purposefully not administered the study drug.

                                       36

A comparator-controlled study is one in which a subset of patients is
administered a medication that is currently prescribed to treat the condition
in order to directly compare the study drug to approved therapies.

   All of our product candidates offer the ability to deliver an approved drug
into the bloodstream through a fast and effective route of administration.
Three of our product candidates are administered by a nasal spray, and one is
administrated intravenously. Nasal delivery is an ideal route for drug
administration as it does not require intravenous or intramuscular injections.
The large surface area, uniform temperature, high permeability and high
density of blood vessels in the lining of the nasal cavity all contribute to
the rapid absorption of drugs into the bloodstream. The nasal route of
delivery is also a good alternative for patients who have difficulty
swallowing oral products.

   Drugs that are administered orally are absorbed from the blood vessels that
line the stomach and pass through the liver where they may be metabolized to
an inactive form. This process is referred to as first pass metabolism. By
contrast, our product candidates enter the bloodstream directly through
intravenous administration or through the blood vessels of the nasal cavity
and avoid the phenomenon of first pass metabolism. By avoiding first pass
metabolism, it is possible to achieve higher concentrations of the active drug
circulating in the bloodstream.

   The following table identifies our current product candidates according to
clinical indication and stage of development in the United States and the
United Kingdom:

Intranasal Ketamine

   Background

   Ketamine is a non-opiate, N-methyl-D-aspartate, or NMDA, receptor antagonist
that has been in clinical use for over 25 years as a general anesthetic. Since
its approval by the FDA, ketamine has been safely used for anesthesia in tens
of thousands of patients. NMDA receptors are located in the central nervous
system and play a role in the perception of pain. Ketamine blocks NMDA
receptors, and therefore it is a logical drug candidate for use as an
analgesic for syndromes associated with acute pain, including breakthrough
pain. A large body of clinical literature describes the off-label use and
effectiveness of lower doses of ketamine than that approved for use as an
anesthetic in providing pain relief for postoperative pain, emergency medical
procedures and neuropathic pain, cancer pain, including breakthrough pain, and
other acute pain. In addition, several of these publications report the
ability of ketamine to increase the potency of the analgesic effects, as well
as reduce the overall requirement of, co-administered opioid pain relievers.

   The use of ketamine as an analgesic is gaining acceptance by clinicians in
view of its effectiveness and minimal impact on cardiovascular and respiratory
functions. Since ketamine is not approved for use as a pain reliever,
physicians have resorted to using the drug off-label. We believe that an FDA-
approved formulation of ketamine for the treatment of moderate-to-severe pain
will provide physicians with an accepted and regulated alternative to off-
label use. In addition, in 1999 ketamine was labeled by the Drug Enforcement
Agency, or DEA, as a Schedule III controlled substance. The scheduling of
ketamine by the DEA provides additional protection with respect to controlling
potential misuse by placing restrictions on the ability to prescribe and
distribute the drug.


                                       37

   Clinical Results

   Our intranasal ketamine product is in clinical development for the treatment
of a heterogeneous group of syndromes associated with acute pain and acute
episodes of chronic pain. To obtain the information that will be required by
the FDA to demonstrate safety and effectiveness in these two pain categories,
we are pursuing a development program of intranasal ketamine along two
clinical paths. The first path focuses on the development of intranasal
ketamine for acute indications, including postoperative pain. The second path
focuses on the development of intranasal ketamine for acute episodes of
chronic pain, including breakthrough cancer pain.


   All of our clinical trials for intranasal ketamine are being performed in
the U.S. under a company-sponsored IND. We have successfully completed three
Phase II clinical trials and one Phase I clinical trial of intranasal ketamine
in a total of 118 patients and volunteers. In these trials, a total of 98
patients and volunteers have received doses of intranasal ketamine. Seventy-
eight of these patients and volunteers received intranasal ketamine in our
Phase I and two of our Phase II acute pain trials. Twenty patients and
volunteers received intranasal ketamine in our Phase II breakthrough pain
trial. Based on the results of these completed trials, we expect to complete
final reports and to present the data from our Phase II clinical trials, in
addition to our Phase III clinical designs, to the FDA in the first half of
2002. At our subsequent End-of-Phase II meeting, we will seek feedback from
the FDA regarding the trial design of our future clinical trials. We
anticipate initiating Phase III clinical trials shortly thereafter.


   Acute Indications

   In the second quarter of 2001, we completed a placebo-controlled Phase II
randomized, double-blind trial evaluating the safety and effectiveness of
three dose levels of intranasal ketamine for the treatment of moderate-to-
severe postoperative pain in 40 patients undergoing the removal of two to four
wisdom teeth. In this trial, we demonstrated the following results:

   o compared to a placebo, all three dose levels of intranasal ketamine
     provided significant postoperative pain relief,

   o intranasal ketamine is fast-acting, with onset of pain relief generally
     occurring within two to ten minutes following administration,

   o both analgesic effectiveness and duration of effect depended on the dose
     of intranasal ketamine, and

   o intranasal ketamine appears to be safe and well-tolerated by patients.

   Patients enrolled in this trial received either placebo or one of three
doses of intranasal ketamine upon the onset of moderate-to-severe pain
following dental surgery. Both pain intensity and pain relief were evaluated
at specific time intervals over a three-hour period following the
administration of intranasal ketamine. These evaluations were performed using
several categorical and visual scales that are well established and widely
used in evaluating drugs for the treatment of pain. Patient vital signs,
including heart rate and blood pressure, were measured throughout the study,
and physical examinations and nasal examinations were performed prior to
treatment and after completion of the study. Patients who did not receive
adequate pain relief within an hour were administered a "rescue" medication to
treat their pain.

   As illustrated in the graph, each dose level of intranasal ketamine
demonstrated pain relief, with the highest dose having the fastest onset,
highest peak and longest duration of effect. Pain relief was calculated as the
difference between baseline pain and the pain intensity measured at specified
timepoints over the initial 60 minute observation phase. In this trial, the
onset of pain relief was rapid in each of the three dose groups of intranasal
ketamine. Maximum pain relief was attained 30 minutes following dose
administration. No harmful effects on heart rate or blood pressure were found
and assessment of patient vital signs and the results of physical and nasal
examinations indicated that intranasal ketamine was well-tolerated. Based on
the results of this study, we believe that intranasal ketamine may offer a
safe, non-opioid alternative for the treatment of moderate-to-severe
postoperative pain.

   In the third quarter of 2001, we initiated, and successfully completed, a
second 40-patient Phase II clinical trial of intranasal ketamine for the
treatment of acute pain. This trial was designed to confirm the safety and
effectiveness and determine the minimum effective dose of intranasal ketamine
required by patients suffering from moderate-to-severe postoperative pain.
Patients enrolled in this study received either placebo or one of three doses
of intranasal ketamine upon the onset of moderate-to-severe pain following
dental surgery. The parameters used to evaluate safety and effectiveness of
intranasal ketamine in this second Phase II clinical trial were identical to
that of the previous Phase II clinical trial. However in this study, the
highest dose of intranasal ketamine tested was equal to the lowest dose tested
in the earlier Phase II clinical trial.

   In this trial, we demonstrated the following results:

   o intranasal ketamine generally provides pain relief within two to ten
     minutes following administration,

   o the amount and duration of pain relief depends on the dose of intranasal
     ketamine,

   o intranasal ketamine appears to be safe and well-tolerated by patients,
     and

   o at very low doses, intranasal ketamine provides minimum and limited pain
     relief.

   Our clinical trial results suggest that intranasal ketamine provides rapid
onset of pain relief with dose-related effectiveness and duration of effect.
In the fourth quarter of 2001, we initiated a Phase II clinical trial
conducted at multiple clinical sites of intranasal ketamine for the treatment
of moderate-to-severe pain associated with orthopedic injury. We began
enrolling patients for this study during the first half of 2002.

   Acute Episodes of Chronic Pain

   In the fourth quarter of 2001, we completed a Phase II clinical trial
conducted at multiple clinical sites that evaluated the safety and
effectiveness of intranasal ketamine for the treatment of moderate-to-severe
episodes of breakthrough pain. Patients who enrolled in this trial had a
documented history of chronic debilitating malignant pain and most were
considered opioid tolerant. The trial was designed as a placebo-controlled,
double-blind crossover trial in 20 patients experiencing severe breakthrough
pain episodes. In this trial, we demonstrated the following results:

   o compared to placebo, intranasal ketamine provided statistically
     significant relief for breakthrough pain,

   o intranasal ketamine is fast-acting with measurable pain relief obtained
     within five minutes of administration,


                                       39

   o intranasal ketamine provided significant pain relief over the one-hour
     treatment period, and

   o intranasal ketamine appears to be safe and well tolerated by patients.

   Patients enrolled in this trial were given either placebo or intranasal
ketamine upon inception of their first breakthrough pain episode and
instructed to administer a fixed dose of up to five sprays until adequate pain
relief was achieved. The alternate substance was administered in an identical
fashion for the second breakthrough pain episode. For each breakthrough
episode, a rating of the patient's pain intensity was measured using a
numerical scale at the onset of the breakthrough pain episode and at specific
time intervals over a one-hour period following the administration of
intranasal ketamine or placebo. The use of a numeric pain intensity scale is a
well-established and widely used tool for evaluating drugs for the treatment
of pain. Patient vital signs, including heart rate and blood pressure, were
measured throughout the study, and physical examination and nasal examinations
were performed prior to treatment and after completion of the study. Patients
who did not receive adequate pain relief within 7.5 minutes were administered
the "rescue" medication they routinely used to treat their breakthrough pain.

   The results of our clinical trial suggests that intranasal ketamine provides
rapid onset of relief for breakthrough pain syndromes. As illustrated in the
graph, as compared to placebo, intranasal ketamine demonstrated a significant
reduction in breakthrough pain intensity over the duration of the breakthrough
pain episode. The onset of action of intranasal ketamine was rapid and
statistically different from the placebo, occurring within four minutes after
administration of the fifth, and final, spray. No harmful effects on heart
rate or blood pressure were found and assessment of patient vital signs and
the results of physical and nasal examinations indicated that intranasal
ketamine was well-tolerated. Based on the results of this study, we believe
that intranasal ketamine may offer a safe, non-opioid alternative for the
treatment of moderate-to-severe breakthrough pain.

Intranasal Morphine

   Background

   Morphine, the analgesic standard to which all other opioids are usually
compared, is a potent agonist of the mu-opioid receptor. When morphine binds
to its receptor, it inhibits the transmission of pain signals from nerve
endings to the central nervous system. The ability of morphine to reduce pain
places it among the most important naturally occurring compounds. Morphine is
a strong analgesic used for the relief of acute and chronic moderate-to-severe
pain, preoperative sedation and as a supplement to anesthesia. It is the drug
of


                                       40

choice for pain associated with myocardial infarction and cancer. The calming
effect produced by morphine is also used to protect the system against
exhaustion in traumatic shock, internal hemorrhage, congestive heart failure
and other debilitating conditions.

   Chitosan Delivery Platform


   We have licensed a proprietary drug delivery technology that allows us to
achieve therapeutic blood levels of drugs that were previously unattainable when
they were administered through the nasal route. The key to this technology is
chitosan, a naturally occurring carbohydrate polymer that, while
pharmaceutically inert by itself, enhances the absorption of compounds across
mucosal membranes, such as those found in the nasal cavity, and provides the
potential to deliver drugs through alternative routes. This is particularly
important for compounds such as morphine that are poorly absorbed across mucosal
barriers and, in particular, the nasal membrane. The contribution of chitosan to
enhancing mucosal drug absorption appears to be due to several factors,
including its potent mucoadhesive property, which we believe prevents drug
washout.


   The following graph illustrates the increase in the nasal absorption of
morphine associated with chitosan in our intranasal morphine product
candidate. Data from published, historical studies report that effective pain
relief is often associated with a patient attaining or exceeding morphine
blood levels of 19 nanograms per milliliter. Data from our study demonstrated
that our formulation of intranasal morphine rapidly delivers and exceeds this
threshold within five minutes following administration.

   Conventional oral formulations of morphine do not provide rapid relief of
pain in many patients. Aside from its slow and variable onset of action, oral
morphine demonstrates considerable patient-to-patient variability in
absorption and has relatively low blood levels of active drug. Clinicians must
therefore often rely on injectable types of morphine preparations to assure
rapid and effective pain relief. Administration of injectable morphine often
requires professional assistance or hospitalization. Therefore, alternative
formulations of morphine that are easy to administer by a patient or caregiver
and afford rapid onset of action and high blood levels of active drug would
provide significant medical benefit. We believe that intranasal morphine
represents an alternative formulation that combines the promise of patient
convenience, ease of use and cost-effectiveness with the rapid onset of pain
relief and the well-accepted potency of injectable delivery routes.

   Clinical Results

   Our intranasal morphine product candidate is in clinical development for the
treatment of a heterogeneous group of syndromes associated with acute pain and
acute episodes of chronic pain. We have

                                       41


completed two Phase I clinical trials and have completed a Phase II clinical
trial of our intranasal morphine product candidate.



   We have successfully completed both single- and multiple-dose Phase I
clinical trials in the U.S. and the United Kingdom, evaluating the
tolerability and resulting blood levels of three dose levels of intranasal
morphine in normal patients. In both trials, we demonstrated the following
results:


   o all three dose levels of intranasal morphine are rapidly absorbed and
     achieve blood levels typically associated with analgesic effectiveness of
     morphine generally in as early as five to ten minutes following
     administration,

   o the safety profile of intranasal morphine was comparable to other
     formulations of morphine,

   o blood levels of intranasal morphine varied depending on the dose
     administered, and

   o intranasal morphine was well tolerated by the mucous membranes of the
     nasal cavity.


   In the first quarter of 2002, we completed a placebo and comparator-
controlled Phase II randomized double-blind trial of two dose levels of
intranasal morphine. This trial was designed to compare the safety and efficacy
of two different dose levels of intranasal morphine with placebo, intravenous
morphine and oral morphine in patients suffering from moderate to severe
postoperative pain. Patients enrolled in this trial received either placebo or
one of either of two doses of intranasal morphine, oral morphine or intravenous
morphine upon the onset of moderate to severe pain following dental surgery. In
this trial we demonstrated both doses of intranasal morphine were statistically
superior to placebo and statistically similar to the positive comparators.
Intranasal morphine was well tolerated in this patient population and there were
no serious adverse events and no withdrawals due to adverse events or other
safety concerns. We expect to complete the study report in the second quarter of
2002 and to present our data from our clinical trials, in addition to our
proposed Phase III clinical trial designs, to the FDA by mid-2002.

   The following graph illustrates the blood levels obtained in our Phase I
clinical trial with our intranasal morphine product candidate as compared to
an identical dose of immediate release oral morphine and an infusion dose of
intravenous morphine. The steep slope of the plasma concentration curve at the
initial times following drug administration suggests that the intranasal
morphine product candidate is rapidly delivered to the bloodstream. By
contrast to oral morphine, the plasma concentration curves for intravenous
morphine and intranasal morphine are very similar, suggesting similar onset of
action and duration of pain relief.

Intravenous Diclofenac

   Background

   In December 2001, we acquired the rights to develop a novel, proprietary
intravenous formulation of diclofenac from Shimoda and Farmarc. Diclofenac is
one of the most potent NSAIDs known clinically for both inflammation and pain.
It is also one of the world's most prescribed anti-inflammatory agents due to
a combination of efficacy and tolerability.

   The exact mechanism of action of diclofenac and other NSAIDs has not been
fully determined but appears to be associated with inhibiting the body's
ability to synthesize prostaglandins. Prostaglandins are a family of hormone-
like chemicals, some of which are made in response to tissue injury and
produce inflammation and pain. In particular, diclofenac inhibits the
synthesis of the enzyme cyclooxygenase, or COX, that is necessary for the
formation of prostaglandins during tissue injury. COX enzymes exist in two
forms known as COX-1 and COX-2. COX-1 protects the stomach lining and
intestines and COX-2 is involved in making the prostaglandins that are
responsible for inflammation and pain. NSAIDs that preferentially inhibit COX-
1, such as aspirin, are associated with undesirable gastric side-effects,
including stomach irritation and ulcers. NSAIDs that preferentially inhibit
COX-2, such as diclofenac, have a more desirable side-effect profile than COX-
1 inhibitors.

   Cyclodextrin Delivery Platform

   The key to the intravenous formulation of diclofenac that we have in-
licensed is hydroxypropyl--cyclodextrin, or HPBCD. Cyclodextrins, such as
HPBCD, are donut-shaped carbohydrate molecules that can improve the solubility
of poorly soluble drugs such as diclofenac. By improving the solubility of
diclofenac, HPBCD provides a means to create an intravenous formulation that
can efficiently deliver the drug to the patient's bloodstream. While there are
many types of cyclodextrins, only modified cyclodextrins such as HPBCD are
regarded as safe for injection.

   NSAIDs offer several advantages over the more traditional opioid narcotics
for the management of postoperative pain. NSAIDs have limited effect on the
central nervous system, do not depress respiration and are non-sedating. This
latter attribute is of special importance in intermediate, ambulatory surgery
since NSAIDs can provide analgesia without delaying discharge from the
hospital or outpatient setting. In addition, NSAIDs are also useful in
patients who cannot take opioids.

   There exists an unmet medical need for a safe and effective injectable NSAID
in the hospital setting. Diclofenac is currently approved for use in the U.S.
in a variety of oral formulations as well as a topical and ophthalmic
formulation. An intramuscular formulation of diclofenac is commercially
available in Europe. The development of injectable formulations of diclofenac
have been limited by the drug's poor solubility in water and susceptibility to
breakdown. We believe that the proprietary formulation of diclofenac that we
have in-licensed has the potential to overcome these issues and may provide an
effective and safe treatment of moderate-to-severe acute pain.

   Clinical Results

   Our intravenous diclofenac product candidate has been evaluated in Phase I
clinical trials performed in South Africa and a Phase II clinical trial
performed in the United Kingdom, with both sets of trials being conducted on
behalf of a third party with a relationship with our licensor. We anticipate
filing an IND for our formulation of intravenous diclofenac in the first half
of 2002 in order to initiate a U.S. clinical development program. Based on the
results of the Phase I and Phase II clinical trials that have already been
conducted outside of the U.S., combined with the extensive published
literature on the safety and effectiveness of diclofenac, the FDA has
indicated that Phase I and single-dose Phase II clinical trials may be
initiated concurrently upon allowance of an IND.

   A 269-patient Phase II clinical trial has been completed in the United
Kingdom evaluating the safety and effectiveness of intravenous diclofenac for
the treatment of acute postoperative pain. This trial was conducted on behalf
of a third party with a relationship with our licensor and was a randomized,
double-blind, placebo-controlled study conducted at multiple clinical sites to
evaluate the safety, effectiveness and tolerability of


                                       43

three dose levels of intravenous diclofenac for the treatment of pain
following removal of one or more impacted wisdom teeth. This trial
demonstrated the following:

   o compared to placebo, all three dose levels of intravenous diclofenac
     provided statistically significant pain relief and delayed the need for
     rescue medication, and

   o at all three dose levels, intravenous diclofenac appears to be safe and
     well-tolerated.

   The following graph illustrates the effect of all three dose levels of
intravenous diclofenac compared to placebo on pain intensity following dental
surgery. Pain intensity was measured on a 100 point scale, with zero
representing no pain and 100 representing the most intense pain imaginable.
Upon onset of moderate to severe pain following surgery, patients were treated
with either intravenous diclofenac or placebo. By comparison to placebo, there
was a rapid drop in pain intensity with all three dose levels of intravenous
diclofenac. This drop in pain intensity is characteristic of effective pain
medications when delivered by the intravenous route.

Intranasal Fentanyl

   Fentanyl is a synthetic opioid that was originally approved by the FDA in
1968 and is commercially available in formulations for transdermal,
transmucosal and injectable delivery. Fentanyl has a similar effect on the
body as morphine. The actions of fentanyl are similar to those of morphine,
although fentanyl is much more potent and has a more rapid onset of action. By
comparison, while the analgesic potency of fentanyl is some 75 to 100 times
that of morphine, its duration of effect is shorter.

   Fentanyl is a widely-used and effective opioid analgesic for treating
chronic moderate-to-severe pain, including cancer pain. When administered
using a transdermal patch that provides a controlled rate of delivery,
fentanyl is effective in controlling the chronic pain associated with cancer.
A fentanyl drug matrix in a lollipop format, Actiq, was approved in 1998 for
the treatment of breakthrough pain in cancer patients who are already
receiving and tolerating opioid therapy for their pain. This oral,
transmucosal formulation of fentanyl is the first opioid approved specifically
for this indication and is frequently used as an adjunct to the fentanyl patch
to control these flareup pain episodes.

   We believe that an intranasal formulation of fentanyl could also be used to
complement the fentanyl transdermal patch, as well as oral morphine
controlled-release formulations, to effectively treat episodes of breakthrough
pain. Intranasal fentanyl may offer several advantages over existing fentanyl-
based products for the management of breakthrough pain, including rapid and
consistent onset of action, coupled with certain


                                       44

cost and safety advantages. Nasal delivery of fentanyl could provide an
advantage for cancer patients who, as a side effect of chemotherapy, have
difficulty swallowing due to oral ulcerations.

   Intranasal fentanyl is currently in preclinical development using our
chitosan delivery platform technology.

Our Strategy

   Our goal is to become a leading specialty pharmaceutical company that
develops and commercializes new drugs for the management of pain in order to
fulfill unmet medical needs. Our strategies to accomplish this goal include
the following:

   o Develop New Products with Reduced Clinical and Regulatory Risk.  We intend
     to develop drugs that we believe have lower clinical and regulatory risks
     compared to the development of new chemical entities. Our current product
     candidates, intranasal ketamine, intranasal morphine, intravenous
     diclofenac and intranasal fentanyl, combine drugs and natural compounds
     whose safety and pharmacology are well established and have been
     independently approved by the FDA.

   o Focus on Large Markets Where Our Product Candidates Can Address Unmet
     Medical Needs.  We intend to maintain a portfolio of product candidates
     that address important medical needs in large markets. All of our current
     product candidates address the management of moderate-to-severe pain in
     several indications that we believe are underserved by current
     therapeutic treatment options. Pharmaceuticals for the treatment of pain
     represent one of the largest drug categories in terms of sales, and this
     market segment is continuing to expand due to a combination of factors,
     including the increased focus on the importance of effective pain
     management by the healthcare industry.

   o Focus on Clinical Development and Late-Stage Product Candidates.  We will
     continue to devote significant effort toward designing and managing
     clinical trials for late stage product candidates we acquire or in-
     license. Three of our current product candidates are in Phase II clinical
     trials. The conduct of human trials is a complex, highly regulated and
     highly specialized effort. We believe that our clinical development focus
     will enable us to create successful therapeutic products more rapidly and
     more efficiently than if we were developing new chemical entities.

   o Retain Significant Rights to Our Product Candidates.  We currently retain
     exclusive worldwide commercialization rights to all of our pain
     management product candidates in all markets and indications. In general,
     we intend to independently develop our product candidates through late-
     stage clinical trials. As a result, we expect to capture a greater
     percentage of the profits from drug sales than we would if we out-
     licensed our drugs earlier in the development process.

   o Use Our Technology Platforms to Develop New Product Candidates.  We
     believe our proprietary formulation technologies are broadly applicable
     to pain management. We intend to leverage these technologies to develop
     treatments across multiple indications.

   o Outsource Key Functions.  We will continue to outsource components of
     preclinical studies, clinical trials, formulation and manufacturing. We
     intend to both contract with outside sales organizations and enter into
     distribution agreements with pharmaceutical partners to sell our
     products. We believe that outsourcing these functions will enable us to
     focus our resources on developing existing and new product candidates and
     to quickly commercialize these products. We may enter markets that demand
     highly specialized sales and marketing efforts. In such cases, we may
     seek sales and marketing alliances with third parties. We believe that
     such alliances will enable us to commercialize our future products in a
     more rapid and cost-effective manner.

Competitive Grants

   We have received the following grants that provide both financial and
development support for several of our clinical programs:


                                       45

   U.S. Military

   We were awarded a grant of approximately $1.2 million in the third quarter
of 2000 to be paid over a three-year period from the U.S. Department of
Defense to develop intranasal ketamine for the treatment of acute moderate-to-
severe pain associated with traumatic orthopedic injury. This award, entitled
"A Non-Opiate, Nasally Administered Alternative to Injection of Morphine
Sulfate For the Treatment of Pain in Military Casualties," is based on the
desire of the military for a fast-acting, non-invasive and non-sedating
alternative to the intravenous and oral medications commonly used today for
treating combat related injuries such as burns, bullet wounds and blunt trauma
associated with mass casualty management. We initiated patient enrollment in
the first quarter of 2002.

   National Institutes of Health/National Cancer Institute

   In the third quarter of 2000, we were awarded a Phase I grant from the
National Institutes of Health/National Cancer Institute Small Business
Innovation Research Award for "The Development of Transnasal Ketamine for
Breakthrough Pain." This award provided approximately $298,000 of funding for
a period of one year from the National Cancer Institute for the development of
intranasal ketamine as an analgesic for intractable malignant pain, such as
breakthrough cancer pain, based on its potential to provide a substantial
medical benefit in an area of unmet medical need.

Strategic Agreements


   We have entered into a license agreement with Dr. Stuart Weg, a number of
strategic agreements with West Pharmaceutical related to its proprietary
chitosan intranasal delivery technology for the administration of morphine,
fentanyl and other compounds and an agreement with Shimoda and the Farmarc
companies.

   Ketamine License


   In February 1998, Pain Management entered into a license agreement with Dr.
Stuart Weg. We assumed the license agreement upon the closing of our merger
with Pain Management. The license grants us the exclusive worldwide rights,
including the right to grant sublicenses, for the intellectual property
surrounding intranasal ketamine. In connection with the license agreement, we
made an upfront payment to Dr. Weg, Dr. Herbert Brotspies and Calgar &
Associates and issued them shares of our common stock, a portion of which is
currently held in escrow and will be released to them upon the successful
completion of a Phase III clinical trial for ketamine, if at all. Dr. Weg, one
of our principal stockholders, was issued 757,983 shares of our common stock in
February 1998. An additional 189,495 shares are held in escrow. We also
reimbursed Dr. Weg, Dr. Brotspies and Calgar for patent and other costs. We
will pay semi-annual royalty payments to them based on a percentage of net
sales of intranasal ketamine sold by us or our sublicensees, if any. In
addition, we will pay Dr. Weg, Dr. Brotspies and Calgar a defined percentage
of all sublicensing fees or other lump sum payments. Under this agreement, we
have made aggregate payments to Dr. Weg, Dr. Brotspies and Calgar of $300,000
in cash as of December 31, 2001. We are obligated to make aggregate future
payments of approximately $1.3 million upon the earlier of certain defined
dates ranging from August 2003 to November 2004 or satisfaction of certain
clinical and regulatory milestones, which includes the filing of an NDA with
the FDA, the approval of an NDA by the FDA and the first commercial sale of a
licensed product. A defined percentage of such milestone payments will be
creditable against royalties earned, provided that in no event will royalties
earned be reduced by more than a certain percentage in any applicable semi-
annual period. At our option, we may satisfy a portion of the milestone
payments through the issuance of shares of our common stock if we are publicly
traded at the time the milestone payment accrues. Dr. Weg will have the right
to terminate this agreement upon 60 days' notice to us if we fail to pay him
royalties due under the agreement or in the event we breach the agreement and
fail to cure the breach or pay the royalties within the 60-day period. The
agreement may also be terminated by mutual agreement or on the date the last
patent under the agreement expires. In addition, we may terminate the
agreement in whole or in part as to any portion of the patent rights upon 60
days' prior notice.



                                       46

   West Pharmaceutical Agreements


   In August 2000, we entered into a license agreement, which was amended in
October 2001, with West Pharmaceutical under which we have a worldwide exclusive
right to develop and commercialize products, including intranasal morphine and
intranasal fentanyl under patents held by West Pharmaceutical, for the
transmucosal delivery to humans and animals of morphine and fentanyl for the
treatment of pain. Most of these patents expire between 2013 and 2016. As
consideration for the license, we paid West Pharmaceutical up-front license
fees. Under this agreement, we have made aggregate payments to West
Pharmaceutical of approximately $2.3 million in cash, as of December 31, 2001.
In addition, under the license agreement for morphine, fentanyl and other
products, we are obligated to make royalty payments to West Pharmaceutical based
upon net sales of products by us or our sublicensees of these products, if any.
We are also obligated to pay West Pharmaceutical a minimun annual royalty for
each licensed product that receives approval by a regulatory agency to be
marketed in any major market country. We are also obligated to pay West
Pharmaceutical a defined amount of any up-front license fees in the event we
sublicense any rights to any third party.

   The term of the license agreement expires in 2016, which is the date the
last patent expires, unless terminated earlier by the parties. The license
agreement can be terminated by mutual agreement or by either party upon
default by the other party under any one of several of our agreements with
West Pharmaceutical, but only if the breaching party fails to remedy the
default within 30 days of receiving notice from the non-defaulting party. We
can also terminate the license agreement with respect to specific compounds if
the FDA does not allow chitosan in the products contemplated by the agreement.
If the license agreement is terminated for any reason other than West
Pharmaceutical's breach, we must grant to West Pharmaceutical perpetual,
exclusive, worldwide, royalty-free rights to what we develop under the
agreement.

   In connection with the license agreement, in September 2000, we entered into
an intranasal morphine development milestone and option agreement with West
Pharmaceutical. The parties meet regularly to discuss the status of the
development programs and we submit to West Pharmaceutical biannual revised
product plans, the scope and detail of which we believe are consistent with
industry standards. Under this agreement, we have made aggregate payments to
West Pharmaceutical of approximately $2.3 million in cash, as of December 31,
2001. We are obligated to make aggregate future payments totaling $5.0 million
upon reaching certain defined development milestones, which include the
filing of an NDA with the FDA and the approval of an NDA by the FDA of a
licensed product. Milestone payments can be paid in cash or stock upon the
satisfaction of certain clinical and regulatory milestones and provided that
we are publicly traded at the time the milestone payment accrues. In addition,
we granted West Pharmaceutical a right of first refusal to enter into a
commercial manufacturing agreement for nasal morphine. The development
milestone and option agreement remains in effect until our intranasal morphine
product is launched in all specified major country markets, unless earlier
terminated for failure of a defaulting party to remedy its breach within
30 days' notice by the non-defaulting party, within five days' notice from
West Pharmaceutical to us in the event we breach the payment terms in that
agreement or by mutual agreement.

   In September 2000, we entered into a clinical manufacturing agreement with
West Pharmaceutical requiring us to purchase from West Pharmaceutical, for a
period of two years, all of the intranasal morphine required for use in our
intranasal morphine clinical trials, subject to West Pharmaceutical's ability
to supply the full amount we require. The agreement requires West
Pharmaceutical to manufacture the product according to applicable clinical
product specifications. The agreement remains in effect for the earlier of its
two-year term or the last to occur launch date after the clinical product has
been launched in all major market countries, unless terminated earlier for
failure of a defaulting party to remedy its breach within 30 days' notice by
the non-defaulting party, within five days' notice from West Pharmaceutical to
us in the event we breach the payment terms in the agreement or by mutual
agreement. Under this agreement, we have made aggregate payments to West
Pharmaceutical of $127,000 in cash, as of December 31, 2001.


   In September 2000, we entered into an option agreement, whereby we were
granted an option to include morphine-6-glucuronic as a compound under the
license agreement with West Pharmaceutical. We paid and expensed a non-
refundable fee of $300,000 for the option, which expired unexercised in December
2000.



                                       47


   In October 2000, we entered into a research and development and option
agreement with West Pharmaceutical for the development of a product for the
intranasal administration of fentanyl, based upon the intranasal delivery
technology licensed from West Pharmaceutical. Under this agreement, West
Pharmaceutical will conduct preclinical development activities related to
intranasal fentanyl. Under this agreement, we have made no payments to West
Pharmaceutical, as of December 31, 2001. We are obligated to make future
aggregate payments totaling approximtely $6.3 million payable in cash, or if
agreed by both parties, in stock, upon the attainment of specified clinical and
regulatory milestones, including the filing of an NDA and the receipt of the
first approval letter of an NDA in a major country market. Additionally, we have
granted to West Pharmaceutical a right of first negotiation with respect to the
manufacturing and packaging of commercial quantities of the licensed fentanyl
products. This agreement remains in effect until our product covered by the
agreement is launched in all specified major country markets. The agreement,
however, may be terminated earlier for failure of a defaulting party to remedy
its breach within 30 days' notice by the non-defaulting party, within five days'
notice from West Pharmaceutical to us in the event we breach the payment terms
in that agreement or by mutual agreement.

   In November 2000, we entered into a clinical manufacturing contract with
West Pharmaceutical to manufacture, package, purchase and sell to us nasal
ketamine according to agreed upon clinical product specifications and a price
schedule. The contract was fulfilled in November 2001. Under this contract, we
have made aggregate payments to West Pharmaceutical of $320,000 in cash, as of
December 31, 2001.

   In October 2001, we entered into a letter agreement with West Pharmaceutical
amending the license agreement entered into in August 2000 and the intranasal
morphine development milestone and option agreement entered into in September
2000. Pursuant to the amendment, we agreed on the date upon which the
approximately $2.3 million owed in connection with the intranasal morphine
development milestone and option agreement was to be paid to West
Pharmaceutical.


   Shimoda Agreement


   In December 2001, we entered into a license agreement with Shimoda and its
wholly-owned subsidiaries, Farmarc N.A.N.V. (Netherlands Antilles) and
Farmarc, under which we received certain worldwide exclusive rights to develop
and commercialize products related to a proprietary formulation of the
intramuscular and intravenous delivery of diclofenac. Under the terms of this
agreement, we agreed to use our commercially reasonable efforts to bring to
market products that use the technology we licensed from Farmarc and Shimoda,
continue active marketing efforts for those products and comply with the
commercialization timelines imposed on Shimoda by the company that licensed
certain of this technology to Shimoda. Shimoda agreed that, during the first
three years of the agreement, it will not grant to any third party any right
or license under any of Shimoda's intellectual property rights involving the
use of any cyclodextrin product related to pain management, anesthesia or
sedation without first offering us the right on the same terms and conditions.

   Upon entering into the agreement with Shimoda and its subsidiaries, we made
certain payments on Shimoda's behalf to third parties. Under this agreement,
we have made aggregate payments to Shimoda or on its behalf of $550,000 in
cash, as of December 31, 2001. We are obligated to make future payments to
Shimoda and Farmarc, and on Shimoda's behalf, to certain third parties, for a
license fee and other milestone and reimbursement payments in an aggregate
amount of $7.2 million, and if we commercialize products using the technology
under this agreement, we are obligated to pay Shimoda and Farmarc, on a
country-by-country basis, a royalty on the sales, net of various customary
cash discounts, attributable to these products. In addition, we will pay a
minimum of $1.0 million and a maximum of $2.0 million in the aggregate payable
to Shimoda and Farmarc upon the closing of this offering, which payment will
be $1.0 million assuming an initial public offering price of $9.00 per share.
Our obligation to make milestone payments occur upon specified developmental
milestones, including the filing of an IND for diclofenac, the filing of an
NDA for diclofenac, the approval of an NDA by the FDA and the first commercial
sale of a product.


   Shimoda may terminate our agreement upon 15 days' written notice if we fail
to maintain a minimum amount of certain types of insurance and do not produce
to Shimoda written proof of any such insurance within 14 days of Shimoda's
request, and Shimoda or Farmarc may terminate the agreement upon 60 days'
written notice if we fail to make royalty payments on a timely basis. We and
Shimoda have the right to


                                       48

terminate the agreement upon 60 days' written notice if the other party
materially breaches the agreement in any other way. In each case, however, the
defaulting party has the opportunity to cure the payment default or breach of
the agreement in order to prevent termination of the agreement. We also have
the right to terminate the agreement upon 90 days' written notice to the
Shimoda parties. If we terminate under this provision, or if the agreement is
terminated due to our breach, we have agreed to assign to Shimoda (at no cost
to Shimoda) all clinical information and other data developed by us in
furtherance of the development of the products licensed to us.

Competition

   Our success will depend, in part, upon our ability to achieve market share
at the expense of existing and established and future products in our target
markets. Existing and future products, therapies, technological innovations
and delivery systems will compete directly with our products. Competing
products and technologies may provide greater therapeutic benefit for a
specific indication, or may offer comparable performance at a lower cost.
Alternative technologies are being developed to improve the delivery of drugs
within the pain management industry, several of which may be in the clinical
trials stage or are awaiting FDA approval.

   We compete with fully integrated pharmaceutical companies, smaller companies
that are collaborating with larger pharmaceutical companies, academic
institutions, government agencies and other public and private research
institutions. We believe that our competitors include, but are not limited to,
Cephalon, Inc., Merck & Co., Inc., Nastech Pharmaceutical Company Inc., Pain
Therapeutics, Inc and Pharmacia Corporation. Such competitors may also have
access to more resources, financial and otherwise,
which may allow these institutions to develop and market competing products
more rapidly and more effectively than we do.

Intellectual Property

   Our goal is to obtain, maintain and enforce patent protection for our
products, formulations, processes, methods and other proprietary technologies,
preserve our trade secrets, and operate without infringing on the proprietary
rights of other parties, both in the United States and in other countries.
Our policy is to actively seek to obtain, where appropriate, the broadest
intellectual property protection possible for our product candidates,
proprietary information and proprietary technology through a combination of
contractual arrangements and patents, both in the United States and elsewhere
in the world.

   We currently have licenses to five U.S. patents and a number of foreign
counterpart patents and applications, as described below. We have licensed two
U.S. patents and their foreign counterparts from Dr. Stuart Weg, M.D., which
are directed toward the use of ketamine to manage pain and the administration
of ketamine through the nasal route.  We have licensed two U.S. patents and
their foreign counterparts from West Pharmaceutical, which are directed toward
the use of chitosan and pectin for the transmucosal delivery of morphine and
fentanyl. We have licensed one U.S. patent and its foreign counterparts under
the Shimoda license agreement, which are directed toward intravenous
diclofenac formulations and methods of preparing the same.


   The term of a patent is typically 20 years from filing date, subject to any
statutory extension.  If any application contains a specific reference to an
earlier filed application or applications, the term of the patent is 20 years
from the date on which the earliest application was filed, subject to any
statutory extension.  In the United States for applications filed prior to
June 8, 1995, the term of a patent is the longer of 17 years from the date of
grant of the patent and 20 years from the earliest effective U.S. filing date
of the application, subject to any statutory extension. Because the time from
filing to issuance of medical patent applications is often more than three
years, patent protection, if any, on patented medical technologies, such as
our products, may be substantially less than 17 years.


   We also depend upon the skills, knowledge and experience of our scientific
and technical personnel, as well as that of our advisors, consultants and
other contractors, none of which is patentable.  To help protect our
proprietary know-how that is not patentable, and for inventions for which
patents may be difficult to enforce, we rely on trade secret protection and
confidentiality agreements to protect our interests.  To this


                                       49

end, we require all employees, consultants, advisors and certain other
contractors to enter into confidentiality agreements which prohibit the
disclosure of confidential information and, where applicable, require
disclosure and assignment to us of the ideas, developments, discoveries and
inventions important to our business.  Additionally, these confidentiality
agreements require that our employees, consultants and advisors do not bring
to us, or use without proper authorization, any third party's proprietary
technology.

Manufacturing


   We own no manufacturing facilities. However, we contract with qualified
third parties for the manufacture of bulk active pharmaceutical ingredients and
production of clinical supplies. The ingredients and supplies comply with
current good manufacturing practices procedures reviewed by the FDA. We have
entered into agreements with West Pharmaceutical to manufacture our clinical
supplies for intranasal morphine and fentanyl. West Pharmaceutical has also
provided our initial clinical supplies of intranasal ketamine. Intravenous
diclofenac supplies were provided by Cook Pharmaceutical Solutions.


Government Regulation

   The FDA and comparable regulatory agencies in state and local jurisdictions
and in foreign countries impose substantial requirements upon the clinical
development, manufacture and marketing of pharmaceutical products. These
agencies and other federal, state and local entities regulate research and
development activities and the testing, manufacture, quality control, safety,
effectiveness, labeling, storage, record keeping, approval, advertising and
promotion or our products.

   The process required by the FDA under the drug provisions of the federal
Food, Drug and Cosmetics Act before our initial products may be marketed in
the United States generally involves the following:

   o preclinical laboratory and animal tests,

   o submission of an IND which must become effective before human clinical
     trials may begin,

   o adequate and well-controlled human clinical trials to establish the
     safety and efficacy of the product candidate in our intended use,

   o submission to the FDA of an NDA, and

   o FDA approval of an NDA.

   The testing and approval process requires substantial time, effort, and
financial resources and we cannot be certain that any approval will be granted
on a timely basis, if at all.

   Preclinical studies include laboratory evaluation of the product candidate,
its chemistry, formulation and stability, as well as animal studies to assess
the potential safety and efficacy of the product candidate. We then submit the
results of the preclinical studies, together with manufacturing information
and analytical data, to the FDA as part of an IND, which must become effective
before we may begin human clinical trials. The IND automatically becomes
effective 30 days after receipt by the FDA, unless the FDA, within the 30-day
time period, raises concerns or questions about the conduct of the trials as
outlined in the IND and imposes a clinical hold. In such a case, the IND
sponsor and the FDA must resolve any outstanding concerns before clinical
trials can begin. Our submission of an IND may not result in FDA authorization
to commence clinical trials. Further, an independent Institutional Review
Board at each medical center proposing to conduct the clinical trials must
review and approve any clinical study.

   Human clinical trials are typically conducted in three sequential phases
that may overlap:

   o Phase I: The drug is initially introduced into healthy human subjects or
     patients and tested for safety, dosage tolerance, absorption, metabolism,
     distribution and excretion.

   o Phase II: The drug is studied in a limited patient population to identify
     possible adverse effects and safety risks, to determine the efficacy of
     the product for specific targeted diseases and to determine dosage
     tolerance and optimal dosage.

   o Phase III: When Phase II evaluations demonstrate that a dosage range of
     the drug is effective and has an acceptable safety profile, Phase III
     clinical trials are undertaken to further evaluate dosage, clinical


                                       50

     efficacy and to further test for safety in an expanded patient
     population, often at geographically dispersed clinical study sites.

   We cannot be certain that we will successfully complete Phase I, Phase II or
Phase III testing of our product candidates within any specific time period,
if at all. Furthermore, the FDA or the Institutional Review Board or the IND
sponsor may suspend clinical trials at any time on various grounds, including
a finding that the subjects or patients are being exposed to an unacceptable
health risk.

   The results of product development, preclinical studies and clinical trials
are submitted to the FDA as part of an NDA for approval of the marketing and
commercial shipment of the product. The FDA reviews each NDA submitted, and
may request additional information, before accepting the NDA for filing. Once
the FDA accepts the NDA for filing, the FDA has 12 months in which to review
the NDA and respond to the applicant. The review process may be significantly
extended by FDA requests for additional information or clarification regarding
information already provided. The FDA may deny an NDA if the applicable
regulatory criteria are not satisfied or may require additional clinical data.
Even if these data are submitted, the FDA may ultimately decide that the NDA
does not satisfy the criteria for approval. Once issued, the FDA may withdraw
product approval if compliance with regulatory standards is not maintained or
if safety problems occur after the product reaches the market. In addition,
the FDA requires surveillance programs to monitor approved products that have
been commercialized, and the agency has the power to require changes in
labeling or to prevent further marketing of a product based on the results of
these post-marketing programs.

   Satisfaction of the above FDA requirements or similar requirements of state,
local and foreign regulatory agencies typically takes several years and the
actual time required may vary substantially, based upon the type, complexity
and novelty of the pharmaceutical product. Government regulation may delay or
prevent marketing of potential products for a considerable period of time and
impose costly procedures upon our activities. We cannot be certain that the
FDA or any other regulatory agency will grant approval for any of our products
under development on a timely basis, if at all. Success in preclinical studies
or early-stage clinical trials does not assure success in later-stage clinical
trials. Data obtained from preclinical and clinical activities are not always
conclusive and may be susceptible to varying interpretations that could delay,
limit or prevent regulatory approval. Even if a product receives regulatory
approval, the approval may be significantly limited to specific indications.
Further, even after regulatory approval is obtained, later discovery of
previously unknown problems with a product may result in restrictions on the
product or even complete withdrawal of the product from the market. Delays in
obtaining, or failures to obtain regulatory approvals, would have a material
adverse effect on our business.

   Any products manufactured or distributed by us pursuant to FDA clearances or
approvals are subject to pervasive and continuing regulation by the FDA,
including record-keeping requirements and reporting of adverse experiences
with the drug. Drug manufacturers and their subcontractors are required to
register their facilities with the FDA and state agencies, and are subject to
periodic unannounced inspections by the FDA and state agencies for compliance
with good manufacturing practices, which impose procedural and documentation
requirements upon us and our third-party manufacturers. Failure to comply with
these regulations could result, among other things, in suspension of
regulatory approval, recalls, injunctions or civil or criminal sanctions. We
cannot be certain that we or our present or future subcontractors will be able
to comply with these regulations and other FDA regulatory requirements.

   The FDA regulates drug labeling and promotion activities. The FDA has
actively enforced regulations prohibiting the marketing of products for
unapproved uses. Under the FDA Modernization Act of 1997, the FDA will permit
the promotion of a drug for an unapproved use in certain circumstances, but
subject to very stringent requirements. We and our product candidates are also
subject to a variety of state laws and regulations in those states or
localities where our products are or will be marketed. Any applicable state or
local regulations may hinder our ability to market our products in those
states or localities. In addition, whether or not FDA approval has been
obtained, approval of a pharmaceutical product by comparable governmental
regulatory authorities in foreign countries must be obtained prior to the
commencement of clinical trials and subsequent sales and marketing efforts in
those countries. The approval procedure varies in complexity from country to
country, and the time required may be longer or shorter than that required for


                                       51

FDA approval. We may incur significant costs to comply with these laws and
regulations now or in the future.

   The FDA's policies may change and additional government regulations may be
enacted which could prevent or delay regulatory approval of our potential
products. Moreover, increased attention to the containment of health care
costs in the U.S. and in foreign markets could result in new government
regulations that could have a material adverse effect on our business. We
cannot predict the likelihood, nature or extent of adverse governmental
regulation that might arise from future legislative or administrative action,
either in the U.S. or abroad.

Other Regulatory Requirements

   The Controlled Substances Act imposes various registration, record-keeping
and reporting requirements, procurement and manufacturing quotas, labeling and
packaging requirements, security controls and a restriction on prescription
refills on certain pharmaceutical products. A principal factor in determining
the particular requirements, if any, applicable to a product is its actual or
potential abuse profile. A pharmaceutical product may be "scheduled" as a
Schedule I, II, III, IV or V substance, with Schedule I substances considered
to present the highest risk of substance abuse and Schedule V substances the
lowest. Ketamine, morphine and fentanyl are classified as Schedule II and III
substances. In addition, any of our products that contain one of our product
candidates in combination with narcotics will be subject to DEA regulations
relating to manufacturing, storage, distribution and physician prescribing
procedures.

   We are also subject to numerous federal, state and local laws relating to
such matters as safe working conditions, manufacturing practices,
environmental protection, fire hazard control and disposal of hazardous or
potentially hazardous substances. We may incur significant costs to comply
with these laws and regulations now or in the future. The regulatory framework
under which we currently operate may change and any change could have a
material adverse effect on our current and anticipated operations.

Employees


   As of March 31, 2002, we had ten full-time employees, including five
employees with Ph.D. or M.D. degrees. Most members of our senior management
have had prior experience in pharmaceutical or biotechnology companies. None
of our employees is covered by collective bargaining agreements. We believe
that our relations with our employees are good.


Facilities

   We presently maintain our executive offices on a rent-free basis in premises
of approximately 2,500 square feet that we share with Paramount Capital
Investments. We do not have a lease agreement with Paramount Capital
Investments and consequently our use of this space may be terminated at any
time. We currently have an agreement in place with Paramount under which
Paramount has waived any claim for reimbursement for any payments for this
arrangement and will continue to waive any claim for reimbursement for any
similar payments through the end of the third quarter of 2002. We believe that
our existing facilities are adequate for our current needs and that suitable
additional or alternative space will be available without material disruption
of our business and that such space will be available to us in the future on
commercially reasonable terms.

Legal Proceedings

   We are not a party to any legal proceedings.

books and accounts. Our audit committee also performs other duties as may from
time to time be determined. Our audit committee currently consists of three
directors, Dr. Miller, Mr. Siegel and Mr. Watson.

Option Grants During the Year Ended December 31, 2001


   The following table contains information concerning stock options granted in
2001 to each of the executive officers named in the summary compensation
table. The potential realizable value is calculated assuming the fair market
value of the common stock appreciates at the indicated rate for the entire
term of the option and that the option is exercised and sold on the last day
of its term at the appreciated price. These gains are based on assumed rates
of appreciation compounded annually from the dates the respective options were
granted to their expiration date based on an assumed initial public offering
price of $9.00, minus the applicable per share exercise price. Annual rates of
stock price appreciation of 5% and 10% from the initial public offering price
is assumed pursuant to the rules of the Securities and Exchange Commission.
The actual stock price will appreciate over the term of the options at the
assumed 5% and 10% levels or any other defined level. Actual gains, if any, on
exercised stock options will depend on the future performance of our common
stock.

(1)  Upon the closing of this offering, Dr. Firestone will receive an option to
     purchase an additional 750,000 shares of common stock at an exercise price
     equal to the initial public offering price. This option will expire ten
     years from the date of grant. The potential realizable value of this option
     at an assumed initial public offering price of $9.00 per share and an
     assumed annual rate of stock price appreciation of 5% would be $4,245,000
     and of 10% would be $10,757,762. In addition, for serving as a director,
     Dr. Firestone received an option to purchase an additional 50,807 shares of
     common stock in February 2002 at an exercise price of $5.46 per share, of
     which 33,871 shares are currently exercisable. This option will expire in
     February 2012. The potential realizable value of this option at an assumed
     annual rate of stock price appreciation of 5% would be $467,424 and of 10%
     would be $908,616.

Year Ended December 31, 2001 Option Values

   The following table contains information concerning stock options to
purchase common stock held as of December 31, 2001 by each of the officers

Accordingly, the values set forth below have been calculated on the basis of an
assumed initial public offering price per share of $9.00, less the applicable
exercise price per share, multiplied by the number of shares underlying the
options.

Employee Benefit Plans

   2000 Omnibus Stock Incentive Plan.  Our 2000 Omnibus Stock Incentive Plan
was adopted by our board of directors on February 5, 2001 and approved by our
stockholders on February 15, 2001. Our plan was subsequently amended by our
board of directors on March 12, 2002 and approved by our stockholders
on            .


   We have reserved 4,200,000 shares of our common stock for issuance under our
stock incentive plan. The number of shares of common stock reserved for
issuance under our stock incentive plan will automatically increase on the
first trading day in January of each calendar year, beginning in calendar
year 2003, by an amount equal to 5% of the total number of shares of our
common stock outstanding on the last trading day in December of the
preceding calendar year, but in no event will any annual increase
exceed 1,000,000 shares. No participant in our stock incentive plan may be
granted awards with respect to more than 1,000,000 shares of our common
stock per calendar year.


   The individuals eligible to participate in our stock incentive plan include
our officers and other employees, our non-employee board members and any
consultants we hire. Our stock incentive plan provides for the grant of stock
options, stock appreciation rights, or SARs, and direct stock grants. Stock
options are the right to purchase shares of our common stock at a specified
price, which may be less than, equal to or greater than the fair market value
per share on the date of grant. SARs may be granted alone or in connection
with another award, such as a stock option or grant of restricted stock, and
provide for an appreciation distribution from us equal to the increase in the
fair market value per share of common stock from a price specified on the
grant date. If granted in connection with another award, exercise of the SAR
will generally require the surrender of the related award. This appreciation
distribution may be made in cash or in shares of common stock. Direct stock
grants include the grant of performance shares which are distributable to the
holder based on the achievement of specified performance targets, stock which
may be purchased at a price

                                       59

less than, equal to or greater than the fair market value on the date of
purchase, and grants of bonus stock which do not require purchase by the award
recipient. Any of the direct stock grants may be restricted stock, which is
subject to forfeiture by the holder (or repurchase by us) upon the occurrence
of specified events, such as the holder's cessation of service prior to a
specified date.

   The stock incentive plan includes an automatic option grant program for non-
employee directors, under which option grants will automatically be made at
periodic intervals to our non-employee board members to purchase shares of
common stock at an exercise price equal to 100% of the fair market value of
those shares on the grant date.

   The stock incentive plan will be administered by the compensation committee,
except for automatic option grants. This committee will determine which
eligible individuals are to receive option grants, SARs or stock issuances,
the time or times when such awards are to be made, the number of shares
subject to each such award, the status of any granted option as either an
incentive stock option or a non-statutory stock option under the federal tax
laws, the vesting schedule to be in effect for the award and the maximum term
for which any award is to remain outstanding.

   The exercise price for the shares of the common stock subject to option
grants made under our stock incentive plan may be paid in cash or, with
approval of the committee, in shares of common stock, including restricted
shares, valued at the fair market value on the exercise date; however, such
shares must have been held for at least six months prior to the date of
exercise, valued at fair market value. The option may also be exercised
through a same-day sale program without any cash outlay by the optionee. In
addition, the plan administrator may provide financial assistance to one or
more optionees in the exercise of their outstanding options or the purchase of
their unvested shares by allowing the individuals to deliver a full-recourse,
interest-bearing promissory note in payment of the exercise price and any
associated withholding taxes incurred in connection with the exercise or
purchase.

   The compensation committee will have the authority to cancel outstanding
options under the stock incentive plan in return for the grant of new options
for the same or a different number of option shares with an exercise price per
share based upon the fair market value of our common stock on the new grant
date.

   In the event that we are acquired by merger or an asset sale in which we
will not be the surviving entity or in which we will survive as a wholly owned
subsidiary of another entity, each outstanding option will be assumed by the
successor corporation unless the compensation committee determines that the
options will accelerate and vest in full prior to such transaction.
Alternatively, the committee may cancel the options and pay each holder cash
or securities equal, for each cancelled option share, to the per share
consideration received by our stockholders in the transaction less the
exercise price of the option share. The compensation committee will have
complete discretion to structure one or more awards so those awards will vest
in full or in part in connection with such a transaction, upon the holder's
cessation of service within a specified period following such a transaction or
under other circumstances as determined by the compensation committee in its
discretion.

   The compensation committee may also grant awards subject to accelerated
vesting in connection with a successful tender offer for more than 50% of our
outstanding voting stock or a change in the majority of our board through one
or more contested elections for board membership. Such accelerated vesting may
occur either at the time of such transaction or upon the subsequent
termination of the individual's service.

   Under the automatic option grant program, each individual who first becomes
a non-employee board member at any time after the closing of this offering
will automatically receive an option grant for 12,500 shares of our common
stock on the date such individual joins the board, if such individual has not
been in our prior employ, except for our chairman who shall receive an option
grant for 25,000 shares of our common stock. In addition, on the date of each
annual stockholders meeting held after the closing of this offering, each non-
employee board member who is to continue to serve as a non-employee board
member, including each of our current non-employee board members, will
automatically be granted an option to purchase 12,500 shares of our common
stock, except for our chairman who shall receive an option grant for 25,000
shares of our common stock, if such individual has served on our board for at
least six months.


                                       60

   Each automatic grant will have an exercise price per share equal to the fair
market value per share of our common stock on the grant date and will have a
term of ten years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the lower of the exercise
price paid per share and the fair market value at the time of repurchase, any
shares purchased under the option which are not vested at the time of the
optionee's cessation of board service. The shares subject to each initial
12,500 or 25,000 share automatic option grant, as applicable, will vest in a
series of four successive annual installments upon the optionee's completion
of each year of board service over the four-year period measured from the
grant date. The shares subject to each annual share automatic option grant
will vest upon the optionee's completion of one year of board service measured
from the grant date. However, the shares subject to each automatic option
grant will immediately vest in full upon certain changes in control or
ownership or upon the optionee's death or disability while a board member.

   The board may amend or modify the stock incentive plan at any time, subject
to any required stockholder approval. The stock incentive plan will terminate
no later than February 4, 2011.

   Employee Stock Purchase Plan.  Our Employee Stock Purchase Plan was adopted
by our board of directors on March 12, 2002 and approved by the stockholders
on         , 2002. The plan will become effective immediately upon the signing
of the underwriting agreement for this offering. The plan is designed to allow
our eligible employees and the eligible employees of our participating
subsidiaries, if any, to purchase shares of our common stock, at semi-annual
intervals, with their accumulated payroll deductions.

   We will initially reserve 500,000 shares of our common stock for issuance
under the plan. The reserve will automatically increase on the first trading
day in January of each calendar year, beginning in calendar year 2003, by an
amount equal to 0.05% of the total number of shares of our common stock
outstanding on the last trading day in December in the prior calendar year. In
no event will any such annual increase exceed 200,000 shares.

   The plan will have a series of successive overlapping offering periods, with
a new offering period beginning on the first business day of May and November
of each year. Each offering period will have a duration of 24 months, unless
otherwise determined by the compensation committee. However, the initial
offering period may have a duration in excess of 24 months and will start on
the date the underwriting agreement for this offering is signed and will end
on the last business day in October 2002. The next offering period will start
on the first business day in May 2002 and will also end on the last business
day of October 2002.

   Individuals scheduled to work more than eight hours per week for more than
five calendar months per year may join an offering period on the start date of
that period. However, employees may participate in only one offering period at
a time.

   A participant may contribute up to 15% of his or her cash earnings through
payroll deductions, and the accumulated deductions will be applied to the
purchase of shares on each semi-annual purchase date. The purchase price per
share will be equal to 85% of the fair market value per share on the start
date of the offering period in which the participant is enrolled or, if lower,
85% of the fair market value per share on the semi-annual purchase date. Semi-
annual purchase dates will occur on the last business day of April and October
of each year. However, a participant may not purchase more than 5,000 shares
on any purchase date, and not more than 150,000 shares may be purchased in
total by all participants on any purchase date. Our compensation committee
will have the authority to change these limitations for any subsequent
offering period.

   If the fair market value per share of our common stock on any semi-annual
purchase date within a particular offering period is less than the fair market
value per share on the start date of that offering period, then the
participants in that offering period will automatically be transferred and
enrolled in the new two-year offering period which will begin on the next
business day following such purchase date.

   If we are acquired by merger or a sale of substantially all of our assets or
more than 50% of our outstanding voting securities, then all outstanding
purchase rights will automatically be exercised immediately prior to the
effective date of the acquisition. The purchase price in effect for each
participant will be equal to

                                       61

85% of the market value per share on the start date of the offering period in
which the participant is enrolled at the time the acquisition occurs or, if
lower, 85% of the fair market value per share immediately prior to the
acquisition.

   The plan will terminate no later than the last business day of           ,
200 .

   The board may at any time amend, suspend or discontinue the plan. However,
certain amendments may require stockholder approval.

Employment Agreements

   In December 2001, we entered into an employment agreement with Dr. Leonard
L. Firestone, our Chief Executive Officer, which will commence upon the
closing of this offering. The employment agreement has an initial term of
three years, subject to automatic two-year renewal terms, unless terminated by
us at least six months prior to the end of the then-current term. Dr.
Firestone will receive an initial annual base salary of $400,000, subject to
appropriate increases at the discretion of our board of directors. During the
term, Dr. Firestone is entitled to receive a discretionary bonus amount of up
to 150% of his base salary then in effect and option grants to purchase an
annual maximum of 500,000 shares of our common stock, based on the achievement
of certain performance objectives. In addition, concurrently with the closing
of this offering, Dr. Firestone will be granted an option to purchase 750,000
shares of our common stock at an exercise price equal to the initial public
offering price. These options vest with respect to one-third of the shares on
the date of the grant and then in two equal installments on the first and
second annual anniversaries of the date of grant, as long as he remains
employed with us.

   The employment agreement for Dr. Firestone provides that, if he dies,
becomes disabled or is terminated by us for "cause," we will pay to him any
salary accrued and unpaid to the date of such termination. In the case of
death or disability, Dr. Firestone or his legal representative will also
receive any bonus or incentives earned through the date of death or
disability. If we terminate Dr. Firestone without "cause," we are required to
continue to pay Dr. Firestone's salary for 12 months or until the expiration
of the agreement, whichever is longer, any bonuses and incentives accrued but
unpaid prior to the date his employment is terminated, his health benefits for
12 months and accelerate the vesting of all his unvested stock options. Dr.
Firestone may terminate his employment upon one month's written notice to us.
If he terminates his employment with us, we will pay to Dr. Firestone any
salary accrued and unpaid to the date of such termination. In the event of a
change of control, Dr. Firestone may terminate his employment and we will be
obligated to continue to pay to Dr. Firestone his salary for 18 months and any
accrued but unpaid bonuses and incentives and accelerate the vesting of all
his unvested options. In the event that we desire to continue Dr. Firestone's
employment, his employment may be continued for up to 18 months, and upon the
expiration of the term he will be entitled to the same payments set forth in
the preceding sentence.

   None of our other executive officers has entered into employment agreements
with us.

                  RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

   We believe that we have executed all of the transactions set forth below on
terms no less favorable to us than we could have obtained from unaffiliated
third parties. Our intention is to ensure that all future transactions,
including loans, between us and our officers, directors and principal
stockholders and their affiliates, are approved by a majority of our board of
directors, including a majority of the independent and disinterested members
of the board of directors, and are on terms no less favorable to us than those
that we could obtain from unaffiliated third parties.


Office Space, Administrative Services and Financial Support


   We presently maintain our executive offices on a rent-free basis in premises
of approximately 2,500 square feet that we share with Paramount Capital
Investments, LLC. We do not have a lease agreement with Paramount Capital
Investments and consequently our use of this space may be terminated at any
time. We believe we can obtain suitable alternative space without any material
disruption of our business and that such space will be available to us in the
future on commercially reasonable terms.

   In addition, Paramount Capital Investments provides us with back office and
financial support and management services free of charge. We do not have a
management services agreement with Paramount Capital Investments and
consequently our use of their services may be terminated at any time. For the
year ended December 31, 2001, the estimated fair value of the financial
assistance Paramount has provided to us totaled $481,299, which has been
reflected in the accompanying financial statements as an expense in that
period with a corresponding deemed capital contribution. We anticipate
receiving similar support in the year 2002.


Private Placement of Securities


   In April and July 1999, our predecessor corporation, Pain Management, Inc.,
issued promissory notes to purchasers in the total principal amount of
$1,040,000 bearing interest at a rate of 12% per annum for the first year in
which they were outstanding and 15% per annum thereafter. It also issued
warrants to purchase a total of 260,000 shares of its common stock at an
exercise price of $0.01, exercisable on or prior to September 22, 2005.
Immediately upon the closing of our series A convertible preferred stock, the
principal amount and the accrued interest on the notes became due and payable.
We repaid the notes in full, and, following the merger, the warrants to
purchase shares of Pain Management were converted into warrants to purchase an
aggregate of 231,859 shares of our common stock.

shares of our series A convertible preferred stock in the offering for an
aggregate purchase price of $2,000,000.


                                       63

issued an aggregate of 4,648,220 shares of our common stock, or 0.89174482
shares of common stock for each outstanding share of common stock of Pain
Management. We also exchanged warrants to purchase 485,000 shares of Pain
Management common stock with a weighted average exercise price of $0.01 with
warrants to purchase 432,496 shares of our common stock with a weighted average
exercise price of approximately $0.01. In connection with this transaction, we

preferred stock. In connection with the financing, Paramount Capital's designees
received a cash commission equal to $169,943, Wells Fargo's designees received a
cash commission of $182,603 and we have paid other expenses of $121,771. Wells
Fargo is one of the representatives of the underwriters in this offering.


Transactions with Stockholders

   In February 1998, Pain Management entered into a license agreement with Dr.
Stuart Weg.  We assumed the license agreement upon the closing of our merger
with Pain Management. The license grants us the exclusive worldwide rights,
including the right to grant sublicenses, for the intellectual property
surrounding intranasal ketamine.  In connection with the license agreement, we
made an upfront payment to Dr. Weg, Dr. Herbert Brotspies and Calgar &
Associates and issued them shares of our common stock, a portion of which is
currently held in escrow and will be released to them upon the successful
completion of the Phase III clinical trial, if at all. Dr. Weg, one of our
principal stockholders was issued 757,983 shares of our common stock in
February 1998. An additional 189,495 shares are held in escrow.

   In connection with the license agreement, in February 1998, Pain Management
entered into a stockholders agreement with Dr. Lindsay A. Rosenwald, Dr.
Stuart Weg, Herbert Brotspies and Calgar & Associates. We assumed the
obligations under the stockholders agreement upon the closing of our merger
with Pain Management. The stockholders agreement provides the parties with two
piggyback registrations any time we file a registration statement after our
initial public offering. These registration rights will terminate on February

Transactions with Directors and Executive Officers


   In January 2002, we entered into a lease agreement with Experimed Ltd., a
wholly-owned entity of Dr. Leonard L. Firestone, pursuant to which Dr. Firestone
became employed by us as our Chief Executive Officer on January 1, 2001. We have
also entered into an employment agreement with Dr. Firestone. The employment
agreement is effective upon the consummation of our initial public offering and
provides for salary, bonus, benefits and incentives and will supersede the lease
agreement.


   We have included in our certificate of incorporation and bylaws provisions
to eliminate the personal liability of our directors for monetary damages
resulting from breaches of their fiduciary duty to the fullest extent
permitted by the Delaware General Corporation Law and indemnify our directors
and officers to the fullest extent permitted by Section 145 of the Delaware
General Corporation Law, including circumstances in which indemnification is
otherwise discretionary. We believe that these provisions are necessary to
attract and retain qualified persons as directors and officers.

Relationship with Paramount

   Dr. Lindsay A. Rosenwald, one of our principal stockholders, is also the
chairman of Paramount Capital, Paramount Capital Asset Management, Inc. and
Paramount Capital Investments. Dr. Rosenwald has in the past guaranteed
certain of our bank loans totaling $475,000 in the aggregate and the
obligations securing these guarantees have been fulfilled.

   Dr. Mark C. Rogers, Chairman of our board of directors, is also the
president of Paramount Capital, Paramount Capital Asset Management and
Paramount Capital Investments.


                                       64

   Mr. Peter M. Kash, a member of our board of directors, is also a Senior
Managing Director of Paramount Capital and a director of Paramount Capital
Asset Management. He also serves as a director to The Aries Master Fund, The
Aries Master Fund II and Aries Select, Ltd., each a Cayman Island company for
which Paramount Capital Asset Management serves as general partner.

   Dr. Michael Weiser, a member of our board of directors, is also Director of
Research of Paramount Capital Asset Management.

   Dr. Fred H. Mermelstein, our President and Secretary and a member of our
board of directors, is also the Director of Venture Capital of Paramount
Capital Investments.

   In June 2001, we entered into a consulting agreement with Dr. Elizabeth
Rogers, the wife of Dr. Mark C. Rogers, our chairman. Under the consulting
agreement, Dr. E. Rogers provides 10% of her professional time to our clinical
product development team. In consideration for these services, we have agreed
to pay to Dr. E. Rogers a consulting fee equal to $30,000 per year, payable in
equal bi-monthly installments. In addition, we have agreed to reimburse Dr. E.
Rogers for all pre-approved, out-of-pocket expenses incurred on our behalf.
Concurrently with the consummation of this offering, Dr. E. Rogers will be
granted options to purchase 75,000 shares of our common stock at an exercise
price equal to the price of common stock in this initial public offering.


   Paramount Capital pays a portion of the compensation of our executive
officers. Of the $339,341 Dr. Firestone received in 2001, Paramount Capital
paid $45,661. Of the $165,000 Dr. Mermelstein received in 2001, Paramount
Capital paid $45,000. Of the $135,000 Mr. Hamilton received in 2001,
Paramount Capital paid $67,500. Of the $110,000 Dr. Albin received in 2001,
Paramount Capital paid $55,000. Our executive officer's respective salaries
have been paid solely by us since January 1, 2002.


License Agreement Guarantee

   In August 2000, we entered into a license agreement with West Pharmaceutical
under which we received certain worldwide-exclusive rights to develop and
commercialize products including intranasal morphine and intranasal fentanyl
under patents held by West Pharmaceutical. The agreement required us to pay
West Pharmaceutical up-front license fees, milestone payments upon the
successful completion of certain defined events, a portion of any up-front
license fees that we may receive from our sub-licensees, a royalty based upon
our or our sub-licensees' sales of products and minimum annual royalty
payments for each licensed product that receives regulatory approval.
Paramount Capital Investments guaranteed our ability to pay the up-front
license fees to West Pharmaceutical. The guarantee expired upon the payments
by us of the amounts we owed to West Pharmaceutical.

                             PRINCIPAL STOCKHOLDERS


   Except as otherwise set forth below, the following table sets forth certain
information regarding beneficial ownership of our common stock as of March 31,
2002, and as adjusted to reflect the sale of shares offered hereby, by:


   o each person (or group of affiliated persons) who is known by us to own
     more than five percent of the outstanding shares of our common stock,

   o each of our directors,

   o executive officers named in the summary compensation table, and

   o all of our executive officers and directors as a group.


   Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and generally includes voting or investment
power with respect to securities. The principal address of each of the
stockholders listed below is c/o Innovative Drug Delivery Systems, Inc., 787

persons named in the table have sole voting and sole investment power with
respect to all shares beneficially owned by them. All figures include shares
of common stock issuable upon the exercise of options or warrants exercisable
within 60 days of March 31, 2002 and, which are deemed to be outstanding and
to be beneficially owned by the person holding those options or warrants for
the purpose of computing the percentage ownership of that person, but are not
deemed to be outstanding for the purpose of computing the percentage ownership
of any other person. All figures also assume conversion of all outstanding
shares of our series A and series B convertible preferred stock.

                          DESCRIPTION OF CAPITAL STOCK


General

   The following summary assumes the amendment and restatement of our
certificate of incorporation and bylaws to read in their entirety as provided
in the forms of amended and restated certificate of incorporation and bylaws
filed as exhibits to the registration statement of which this prospectus forms
a part. It also reflects changes to our capital structure that will become
effective immediately prior to or upon the closing of this offering.

   The following description of our capital stock does not purport to be
complete and is subject to, and qualified in its entirety by, our amended and
restated certificate of incorporation and amended and restated bylaws, which
we have included as exhibits to the registration statement of which this
prospectus forms a part. Upon the closing of this offering, our authorized
capital stock will consist of 60,000,000 shares of common stock, $0.001 par
value, and 5,000,000 shares of undesignated preferred stock, $0.001 par value.
As of December 31, 2001, there were approximately 182 holders of record of our
capital stock.

Common Stock

   Dividends and Voting. The holders of our common stock are entitled to such
dividends as our board of directors may declare from legally available funds,
subject to the preferences that may be applicable to any shares of preferred
stock then outstanding. The holders of our common stock are entitled to one
vote per share on any matter to be voted upon by stockholders. Our amended and
restated certificate of incorporation does not provide for cumulative voting.
No holder of our common stock will have any preemptive right under the
Delaware General Corporation Law, our certificate of incorporation or our
bylaws to subscribe for any shares of capital stock issued in the future.

   Other Rights. Upon any voluntary or involuntary liquidation, dissolution,
or winding up of our affairs, the holders of our common stock will be entitled
to share ratably in all assets remaining after payment of creditors and
subject to prior distribution rights of our preferred stock. All of the
outstanding shares of common stock are, and the shares offered by us in this
offering will be, fully paid and non-assessable.

Preferred Stock

   As of the closing of this offering, no shares of our preferred stock will be
outstanding. Our certificate of incorporation provides that our board of
directors may by resolution, without further stockholder approval, establish
and issue one or more classes or series of preferred stock, up to an aggregate
of 5,000,000 shares, having the relative voting rights, designations, dividend
rates, liquidation, and other rights, preferences, and limitations as our
board of directors may fix. The holders of our preferred stock may be entitled
to preferences over common stockholders with respect to dividends,
liquidation, dissolution or our winding up in such amounts as our board of
directors may establish.

   The issuance of our preferred stock may have the effect of delaying,
deferring or preventing a change in control of us without further action by
the holders and may adversely affect voting and other rights of holders of our
common stock. In addition, issuance of preferred stock, while providing
desirable flexibility in connection with possible acquisitions and other
corporate purposes, could make it more difficult for a third party to acquire
a majority of the outstanding shares of voting stock. At present, we have no
plans to issue any shares of preferred stock.

Options


   As of February 25, 2002, options to purchase a total of 1,773,557 shares of
common stock were outstanding at a weighted average exercise price of $4.28. An
aggregate of 3,793,544 shares of common stock are reserved under our 2000
Omnibus Stock Incentive Plan for future grants. Since we intend to file a
registration statement on Form S-8 as soon as practicable following the closing
of this offering, any shares issued upon exercise of these options will be
immediately available for sale in the public market, subject to the terms of
lock-up agreements with the underwriters.



                                       68

Warrants

   As of February 25, 2002, there were warrants outstanding to purchase 216,253
shares of our common stock exercisable for approximately $0.01 per share,
which expire in September 2005, and warrants to purchase 407,893 shares of our
common stock exercisable for $3.94 per share, which expire in October 2005. In
addition, 442,395 shares of common stock are issuable upon the exercise and
assumed conversion of 15.83 Unit Purchase Options. The units entitle the
holders to purchase an aggregate of 395,788 shares of our series A convertible
preferred stock (convertible into 402,177 shares of common stock) at $4.40 per
share and 40,218 shares of our common stock at $3.94 per share.

Registration Rights

   Upon the closing of this offering, the holders of approximately 6,646,635
shares of common stock and warrants to purchase up to approximately 635,090
shares of our common stock will have registration rights with respect to their
shares. These rights are provided under the terms of agreements between us and
the holders of these securities. If we propose to register any of our
securities under the Securities Act, other than in connection with this
offering, either for our own account or for the account of other security
holders exercising registration rights, these holders will be entitled to
notice of the registration and are entitled to include shares of common stock
in the registration. The rights are subject to conditions and limitations,
among them the right of the underwriters of an offering to limit the number of
shares included in the registration. In the event West Pharmaceutical elects
to receive all or part of its milestone payments in shares of our common
stock, at any time commencing 30 days following the attainment of certain
milestones, West Pharmaceutical may require us to file up to three
registration statements under the Securities Act at our expense with respect
to their shares of our common stock, and we are required to use our best
efforts to effect the registrations, subject to conditions and limitations. At
any time following 180 days after the date of this prospectus, the holders of
certain shares may require us to file up to one registration statement under
the Securities Act at our expense with respect to their shares of our common
stock, and we are required to use our best efforts to effect the registration,
subject to conditions and limitations.

Anti-takeover Provisions of the Certificate of Incorporation, Bylaws and
Delaware Law

   Some provisions of our amended and restated certificate of incorporation and
our bylaws could discourage potential acquisition proposals and could delay or
prevent a change in control. These provisions also may have the effect of
preventing changes in our management. Our amended and restated certificate of
incorporation authorizes our board to establish one or more series of
undesignated preferred stock, the terms of which can be determined by our
board at the time of issuance. Our amended and restated certificate of
incorporation also provides that all stockholder action must be effected at a
duly called meeting of stockholders and not by written consent. In addition,
our amended and restated certificate of incorporation and bylaws do not permit
our stockholders to call a special meeting of stockholders. Only our Chief
Executive Officer, President, Chairman of the Board or a majority of the board
of directors may be permitted to call a special meeting of stockholders. Our
amended and restated certificate of incorporation also provides for the board
of directors to be divided into three classes, with each director assigned to
a class with a term of three years, and for the total number of directors to
be determined only by the board of directors. Our bylaws require that
stockholders give advance notice to our secretary of any nominations for
director or other business to be brought by stockholders at any stockholders'
meeting, and permit the chairman of the board to adjourn any meeting called by
the stockholders. Our bylaws also require a supermajority vote of members of
the board of directors and stockholders to amend some bylaw provisions.

   We are subject to Section 203 of the Delaware General Corporation Law, which
regulates acquisitions of Delaware corporations. In general, Section 203
prohibits a publicly-held Delaware corporation from engaging in a business
combination with an interested stockholder for a period of three years
following the date the person becomes an interested stockholder, unless:

   o our board of directors approved the business combination or the
     transaction in which the person became an interested stockholder prior to
     the date the person attained this status,


                                       69

   o upon consummation of the transaction that resulted in the person becoming
     an interested stockholder, the person owned at least 85% of the voting
     stock of the corporation outstanding at the time the transaction
     commenced, excluding shares owned by persons who are directors and also
     officers, or

   o on or subsequent to the date the person became an interested stockholder,
     our board of directors approved the business combination and the
     stockholders other than the interested stockholder authorized the
     transaction at an annual or special meeting of stockholders.

   Section 203 defines a "business combination" to include:

   o any merger or consolidation involving the corporation and the interested
     stockholder,

   o any sale, transfer, pledge or other disposition involving the interested
     stockholder of 10% or more of the assets of the corporation,

   o in general, any transaction that results in the issuance or transfer by
     the corporation of any stock of the corporation to the interested
     stockholder, or

   o  the receipt by the interested stockholder of the benefit of any loans,
     advances, guarantees, pledges or other financial benefits provided by or
     through the corporation.

   In general, Section 203 defines an "interested stockholder" as any person
who, together with the person's affiliates and associates, owns, or within
three years prior to the determination of interested stockholder status did
own, 15% or more of a corporation's voting stock.

Number of Directors; Removal; Filling Vacancies

   Our board consists of eight directors and is divided into three classes of
directors serving staggered three-year terms. As a result, approximately one-
third of our board will be elected each year. These provisions, when coupled
with the provision of our amended and restated certificate of incorporation
authorizing the board to fill vacant directorships or increase the size of the
board may deter a stockholder from removing incumbent directors and
simultaneously gaining control of the board.

Bylaws

   Our bylaws are subject to adoption, amendment, alteration, repeal, or
rescission either by our Board of Directors by a vote of a majority of all
directors in office, without the assent or vote of our stockholders, or by the
affirmative vote of the holders of a majority of the outstanding shares of
voting securities.

Transfer Agent

   Our Transfer Agent and Registrar is American Stock Transfer & Trust Company.
Its telephone number is 212-936-5100.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no public market for our common
stock. Future sales of substantial amounts of our common stock in the public
market could reduce prevailing market prices. Sales of substantial amounts of
our common stock in the public market after any restrictions on sale lapse
could adversely affect the prevailing market price of the common stock and
impair our ability to raise equity in the future.

   Upon the closing of this offering, we will have 20,645,327 outstanding
shares of common stock. Of these shares, the 5.6 million shares sold in this
offering will be freely transferable without restriction or further
registration under the Securities Act, except for any shares purchased by an
affiliate of us. The remaining 15,045,327 shares of common stock held by
existing stockholders are restricted securities. Restricted securities may be
sold in the public market only if registered or if they qualify for exemption
from registration described below under Rule 144, 144(k) or 701 promulgated
under the Securities Act.

   As a result of contractual restrictions described below and the provisions
of Rules 144, 144(k) and 701, the restricted shares will be available for sale
in the public market as follows:

   o 5,600,000 shares will be eligible for sale immediately following this
     offering, and

   o 15,045,327 shares will be eligible for sale upon the expiration of the
     lock-up agreements, described below, beginning 180 days after the date of
     this prospectus and when permitted under Rule 144, 144(k) or 701
     promulgated under the Securities Act.

Lock-Up Agreements

   All of our directors, officers, employees and the holders of substantially
all of our securities have entered into lock-up agreements in connection with
this offering. These lock-up agreements generally provide that these holders
will not offer, sell, contract to sell, grant any option to purchase or
otherwise dispose of our common stock or any securities exercisable for or
convertible into our common stock owned by them for a period of 180 days after
the date of this prospectus without the prior written consent of Thomas Weisel
Partners LLC. Notwithstanding possible earlier eligibility for sale under the
provisions of Rules 144, 144(k) and 701, shares subject to lock-up agreements
may not be sold until these agreements expire or are waived by Thomas Weisel
Partners LLC. Holders of approximately 91.28% percent of our stock outstanding
immediately prior to this offering have entered into lock-up agreements.

Rule 144

   In general, under Rule 144 as currently in effect, after the expiration of
the lock-up agreements, a person who has beneficially owned restricted
securities for at least one year would be entitled to sell within any three-
month period a number of shares that does not exceed the greater of:

   o 1% of the number of shares of common stock then outstanding, which will
     equal approximately
     206,453 shares immediately after this offering, and

   o the average reported weekly trading volume of our common stock during the
     four calendar weeks preceding the sale by such person.

   Sales under Rule 144 are also subject to requirements with respect to manner
of sale, notice and the availability of current public information about us.

Rule 144(k)

   Under Rule 144(k), a person who is not deemed to have been our affiliate at
any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years, may sell these
shares without complying with the manner of sale, public information, volume
limitation or notice requirements of Rule 144.


                                       71

Rule 701

   Rule 701 permits our employees, officers, directors or consultants who
purchased shares pursuant to a written compensatory plan or contract to resell
such shares in reliance upon Rule 144, but without compliance with certain
restrictions. Rule 701 provides that affiliates may sell their Rule 701 shares
under Rule 144 90 days after effectiveness of this registration statement
without complying with the holding period requirement and that non-affiliates
may sell such shares in reliance on Rule 144 90 days after effectiveness of
this registration statement without complying with the holding period, public
information, volume limitation or notice requirements of Rule 144.

Registration Rights


   Upon the closing of this offering, the holders of approximately 6,646,635
shares of common stock and warrants to purchase approximately 635,090 shares
of common stock, or their transferees, will be entitled to rights with respect
to the registration of their shares under the Securities Act. Registration of
their shares under the Securities Act would result in these shares becoming
freely tradeable without restriction under the Securities Act, except for
shares purchased by affiliates, immediately upon the effectiveness of such
registration.


Stock Options

   We intend to file a registration statement under the Securities Act after
the closing of this offering to register shares to be issued pursuant to our
2000 Omnibus Stock Incentive Plan and our Employee Stock Purchase Plan. As a
result, shares of our common stock obtained through the exercise of any
options or rights granted under our 2000 Omnibus Stock Incentive Plan will
also be freely tradable in the public market. However, shares held by
affiliates will still be subject to the volume limitation, manner of sale,
notice and public information requirements of Rule 144, unless otherwise
resalable under Rule 701.

       UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS


   The following summary describes the material United States federal income
and estate tax consequences of the ownership of common stock by a non-U.S.
holder as of the date hereof. This discussion does not address all aspects of
United States federal income and estate taxes that may be relevant to a non-
U.S. holder of common stock. For example, in the case of a non-U.S. holder
that is a partnership, the United States tax consequences of holding and
disposing of our common stock may be affected by determinations made at the
partner level. This discussion also does not address foreign, state and local
tax consequences. Special rules may apply to certain non-U.S. holders, such as
insurance companies, tax-exempt organizations, banks, financial institutions,
dealers in securities, holders of securities held as part of a "straddle,"
"hedge" or "conversion transaction," "controlled foreign corporations,"
"passive foreign investment companies," "foreign personal holding companies"
and corporations that accumulate earnings to avoid United States federal
income tax, that are subject to special treatment under the Internal Revenue
Code of 1986, as amended, or the Code. Such persons should consult their own
tax advisors to determine the United States federal, state, local and other
tax consequences that may be relevant to them. Furthermore, the discussion
below is based upon the provisions of the Code, and regulations, rulings and
judicial decisions thereunder as of the date hereof, and these authorities may
be repealed, revoked or modified with retroactive effect so as to result in
United States federal income tax consequences different from those discussed
below.

Persons considering the purchase, ownership or disposition of common stock
should consult their own tax advisors concerning the United States federal
income tax consequences in light of their particular situations as well as any
consequences arising under the laws of any other taxing jurisdiction.

   As used in this section, a "U.S. holder" of common stock means a holder that
is (1) a citizen or resident of the United States, (2) a corporation or
partnership created or organized in or under the laws of the United States or
of any state thereof or in the District of Columbia, unless in the case of a
partnership, United States Treasury regulations provide otherwise, (3) an
estate the income of which is subject to United States federal income taxation
regardless of its source and (4) a trust (A) if a court within the United
States is able to exercise primary supervision over the administration of the
trust and one or more United States persons has the authority to control all
substantial decisions of the trust or (B) that has a valid election in effect
under applicable United States Treasury regulations to be treated as a United
States person. A "non-U.S. holder" is a holder that is not a U.S. holder.

Dividends

   Dividends paid to a non-U.S. holder of common stock generally will be
subject to withholding of United States federal income tax at a 30% rate or
such lower rate as may be specified by an applicable income tax treaty.
However, dividends that are effectively connected with the conduct of a trade
or business by the non-U.S. holder within the United States and, generally,
where a tax treaty applies, are attributable to a United States permanent
establishment of the non-U.S. holder, are not subject to withholding tax, but
instead are subject to United States federal income tax on a net income basis
at applicable graduated individual or corporate rates. Certain certification
and disclosure requirements must be complied with in order for effectively
connected income to be exempt from withholding. Any such effectively connected
dividends received by a foreign corporation may be subject to an additional
"branch profits tax" at a 30% rate or such lower rate as may be specified by
an applicable income tax treaty. A non-U.S. holder of common stock who wishes
to claim the benefit of an applicable treaty rate (and avoid back-up
withholding as discussed below) for dividends paid will be required to satisfy
applicable certification and other requirements and may be required to obtain
a United States taxpayer identification number.

   A non-U.S. holder of common stock eligible for a reduced rate of United
States withholding tax may obtain a refund of any excess amounts withheld by
filing an appropriate claim for refund with the Internal Revenue Service, or
the IRS.


                                       73

Gain on Disposition of Common Stock

   A non-U.S. holder generally will not be subject to United States federal
income tax with respect to gain recognized on a sale or other disposition of
common stock unless (1) the gain is effectively connected with a trade or
business of the non-U.S. holder in the United States and, generally, where a
tax treaty applies, is attributable to a United States permanent establishment
of the non-U.S. holder, (2) in the case of a non-U.S. holder who is an
individual and holds the common stock as a capital asset, such holder is
present in the United States for 183 or more days in the taxable year of the
sale or other disposition and certain other conditions are met or (3) we are
or have been a "U.S. real property holding corporation" for United States
federal income tax purposes.

   A non-U.S. holder described in clause (1) above will be subject to tax on
the net gain derived from the sale under regular graduated United States
federal income tax rates and, if it is a corporation, may be subject to the
branch profits tax at a rate equal to 30% of its effectively connected
earnings and profits or at such lower rate as may be specified by an
applicable income tax treaty. An individual non-U.S. holder described in
clause (2) above will be subject to a flat 30% tax on the gain derived from
the sale, which may be offset by United States source capital losses (even
though the individual is not considered a resident of the United States).

   We believe we are not and do not anticipate becoming a "U.S. real property
holding corporation" for United States federal income tax purposes.

Federal Estate Tax

   Common stock held by an individual non-U.S. holder at the time of death will
be included in such holder's gross estate for United States federal estate tax
purposes, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

   We must report annually to the IRS and to each non-U.S. holder the amount of
dividends paid to such holder and the tax withheld with respect to such
dividends, regardless of whether withholding was required. Copies of the
information returns reporting such dividends and withholding may also be made
available to the tax authorities in the country in which the non-U.S. holder
resides under the provisions of an applicable income tax treaty.

   A non-U.S. holder may be subject to back-up withholding unless applicable
certification requirements are met.

   Payment of the proceeds of a sale of common stock within the United States
or conducted through certain United States related financial intermediaries is
subject to both backup withholding and information reporting unless the
beneficial owner certifies under penalties of perjury that it is a non-U.S.
holder (and the payor does not have actual knowledge or reason to know that
the beneficial owner is a United States person) or the holder otherwise
establishes an exemption.

   Any amounts withheld under the backup withholding rules may be allowed as a
refund or a credit against such holder's United States federal income tax
liability provided the required information is furnished to the IRS.

                                  UNDERWRITING

   Subject to the terms and conditions set forth in an agreement among the
underwriters and us, each of the underwriters named below, through their
representatives, Thomas Weisel Partners LLC, Wells Fargo Securities, LLC and
Jefferies & Company, Inc. has severally agreed to purchase from us the
aggregate number of shares of common stock set forth opposite its name below:



                                                                              Number

      Total..............................................................    5,600,000

   The underwriting agreement provides that the obligations of the several
underwriters are subject to various conditions. The nature of the
underwriters' obligations commits them to purchase and pay for all of the
shares of common stock listed above if any are purchased.

   Thomas Weisel Partners LLC expects to deliver the shares of common stock to
purchasers on             , 2002.

Over-Allotment Option

   We have granted a 30-day over-allotment option to the underwriters to
purchase up to a total of 280,000 additional shares of our common stock from
us at the initial public offering price, less the underwriting discount
payable by us, as set forth on the cover page of this prospectus. If the
underwriters exercise this option in whole or in part, then each of the
underwriters will be separately committed, subject to conditions described in
the underwriting agreement, to purchase the additional shares of our common
stock in proportion to their respective commitments set forth in the table
above.

Determination of Offering Price

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price will be determined through
negotiations between us and the representatives. In addition to prevailing
market conditions, the factors to be considered in determining the initial
public offering price will include:

   o the valuation multiples of publicly-traded companies that the
     representatives believe are comparable to us,

   o our financial information,

   o our history and prospects and the outlook for our industry,

   o an assessment of our management, our past and present operations, and the
     prospects for, and timing of, our future revenues,

   o the present state of our development and the progress of our business
     plan, and

   o the above factors in relation to market values and various valuation
     measures of other companies engaged in activities similar to ours.

   An active or orderly trading market may never develop for our common stock,
and our common stock  may not trade in the public markets subsequent to this
offering at or above the initial offering price.

Commissions and Discounts

   The underwriters propose to offer the shares of common stock directly to the
public at the public offering price set forth on the cover page of this
prospectus, and at this price less a concession not in excess of $
per share of common stock to other dealers specified in a master agreement
among underwriters who are members of the National Association of Securities
Dealers, Inc. The underwriters may

                                       75

allow, and the other dealers specified may reallow, concessions, not in excess
of $       per share of common stock to these other dealers. After this
offering, the offering price, concessions and other selling terms may be
changed by the underwriters. Our common stock is offered subject to receipt
and acceptance by the underwriters and to other conditions, including the
right to reject orders in whole or in part.

   The following table summarizes the compensation to be paid to the
underwriters by us and the proceeds to us before estimated expenses payable by
us of $2,000,000:

Indemnification of the Underwriters

   We will indemnify the underwriters against some civil liabilities, including
liabilities under the Securities Act of 1933 and liabilities arising from
breaches of our representations and warranties contained in the underwriting
agreement. If we are unable to provide this indemnification, we will
contribute to payments the underwriters may be required to make in respect of
those liabilities.

Reserved Shares

   The underwriters, at our request, have reserved for sale at the initial
public offering price up to 280,000 shares of common stock to be sold in this
offering for sale to our employees and other persons designated by us. The
number of shares available for sale to the general public will be reduced to
the extent that any reserved shares are purchased. Any reserved shares not
purchased in this manner will be offered by the underwriters to the public on
the same basis as the other shares offered in this offering.

No Sales of Similar Securities

   Our directors, officers and stockholders holding substantially all of the
outstanding shares of our capital stock prior to this offering have agreed,
subject to specified exceptions, not to offer, pledge, sell, contract to sell,
sell any option or contract to purchase, purchase any option or contract to
sell, grant any option, right or warrant to purchase, lend or otherwise
transfer or dispose of directly or indirectly, any shares of common stock or
enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of our common stock
or any securities convertible into or exchangeable for shares of our common
stock without the prior written consent of Thomas Weisel Partners LLC for a
period of 180 days after the date of this prospectus.

   We have agreed that for a period of 180 days after the date of this
prospectus we will not, without the prior written consent of Thomas Weisel
Partners LLC, offer, sell, or otherwise dispose of any shares of common stock,
except for the shares of common stock offered in this offering and the shares
of common stock issuable upon exercise of outstanding options and warrants on
the date of this prospectus.

Nasdaq National Market Listing

   We have applied to have our common stock approved for quotation on the
Nasdaq National Market under the symbol "IDDS."

Discretionary Accounts

   The underwriters do not expect sales of shares of our common stock offered
by this prospectus to any accounts over which they exercise discretionary
authority to exceed five percent of the shares offered.


                                       76

Short Sales, Stabilizing Transactions and Penalty Bids

   In order to facilitate this offering, persons participating in this offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of our common stock during and after this offering. Specifically, the
underwriters may engage in the following activities in accordance with the
rules of the Securities and Exchange Commission.

   Short Sales.  Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering. "Covered"
short sales are sales made in an amount not greater than the underwriters'
option to purchase additional shares from the issuer in the offering. The
underwriters may close out any covered short position by either exercising
their option to purchase shares or purchasing shares in the open market. In
determining the source of shares to close out the covered short position, the
underwriters will consider, among other things, the price of shares available
for purchase in the open market as compared to the price at which they may
purchase shares through the over-allotment option. "Naked" short sales are any
sales in excess of such over-allotment option. The underwriters must close out
any naked short position by purchasing shares in the open market. A naked
short position is more likely to be created if the underwriters are concerned
that there may be downward pressure on the price of the common stock in the
open market after pricing that could adversely affect investors who purchase
in the offering.

   Stabilizing Transactions.  The underwriters may make bids for or purchases
of the shares for the purpose of pegging, fixing or maintaining the price of
the shares, so long as stabilizing bids do not exceed a specified maximum.

   Penalty Bids.  If the underwriters purchase shares in the open market in a
stabilizing transaction or syndicate covering transaction, they may reclaim a
selling concession from the underwriters and selling group members who sold
those shares as part of this offering. Stabilization and syndicate covering
transactions may cause the price of the shares to be higher than it would be
in the absence of these transactions. The imposition of a penalty bid might
also have an effect on the price of the shares if it discourages resales of
the shares.

   Any of these activities may have the effect of preventing or retarding a
decline in the market price of our common stock. They may also cause the price
of our common stock to be higher than the price that would otherwise exist in
the open market in the absence of these activities. The transactions above may
occur on the Nasdaq National Market or otherwise. Neither we nor the
underwriters make any representation or prediction as to the effect that the
transactions described above may have on the price of our common stock. If
these transactions are commenced, they may be discontinued without notice at
any time.

Other Relationships

   In December 2001, Wells Fargo Securities, LLC, one of the representatives of
the underwriters, acted as our placement agent in connection with the private
placement of our series B convertible preferred stock for which it received
customary compensation and reimbursement of expenses. In addition, certain
individuals associated with Thomas Weisel Partners LLC and Wells Fargo
Securities, LLC purchased an aggregate of shares of our series B convertible
preferred stock, which upon the closing of this offering will automatically
convert into an aggregate of 54,009 shares of our common stock. Under the
NASD's Conduct Rules, these shares of our series B convertible preferred stock
could be deemed to be underwriting compensation received in connection with
this offering. Accordingly, these individuals have agreed, for a period of one
year, not to sell, transfer, assign, pledge or hypothecate the shares of our
common stock that they will receive upon

conversion of this preferred stock, other than to any NASD member
participating in this offering or an officer or partner of that NASD member.
The underwriters and their affiliates may, from time to time, engage in
transactions with and perform services for us in the ordinary course of our
business.

To the Board of Directors and Stockholders of
Innovative Drug Delivery Systems, Inc.:


   The stock dividend described in Note 1 to the financial statements has not
been consummated at April 9, 2002. When it has been consummated, we will be in
a position to furnish the following report:


   "In our opinion, the accompanying balance sheets and the related statements

                         Notes to Financial Statements

(1) Organization, Business and Basis of Presentation

   Innovative Drug Delivery Systems, Inc. (the "Company" or "IDDS") is a
development stage enterprise engaged in the research, development and
commercialization of innovative treatments for the relief of acute and chronic
moderate to severe pain. The Company is incorporated in the State of Delaware
with operations in a single segment in the United States of America.

   On March 12, 2002, the Company's Board of Directors approved a 1.0161-for-
one split of the outstanding shares of common stock which will be effectuated
as a stock dividend immediately prior to the consummation of this offering.
All common share and per share data included herein have been adjusted as if
the stock dividend had occurred at inception.

   As a development stage enterprise, the Company's primary efforts, to date,
have been devoted to raising capital, forming collaborations for research and
development and recruiting staff. The Company has limited capital resources
and revenues and has experienced net operating losses and negative cash flows
from operations since inception and expects these conditions to continue for
the foreseeable future. At December 31, 2001, the Company had approximately
$7.7 million in cash and cash equivalents. Management believes that cash and
cash equivalents on hand at December 31, 2001 will be sufficient to fund
operations beyond one year. The Company will be required to raise additional
funds to meet long-term planned goals. The Company believes that it will be
able to obtain additional financing through public or private equity
financings, or other arrangements to fund operations. There can be no
assurance that such additional financing, if at all available, can be obtained
on terms acceptable to the Company. If the Company is unable to obtain such
additional financing, future operations will need to be scaled back or
discontinued. On December 31, 2001, the Company closed a private financing
raising net proceeds of approximately $5.0 million through the sale of 989,991
shares of Series B redeemable convertible Preferred Stock (Series B stock)
(see Note 5).

   In addition, to the normal risks associated with a new business venture,
there can be no assurance that the Company's research and development will be
successfully completed or that any approved product will be commercially
viable. In addition, the Company operates in an environment of rapid change in
technology, and is dependent upon the services of its employees, collaborators
and consultants. The Company is solely dependent upon a supplier to supply a
key component in connection with the Company's clinical trials of morphine.

   Pain Management, Inc. (the "Predecessor Company") was incorporated in the
State of Delaware on February 23, 1998. On August 14, 2000, the Predecessor
Company agreed to merge with IDDS. The terms of the merger provided for each
share of the Predecessor Company's common stock to convert into approximately
 .892 share of IDDS common stock as adjusted for a 0.0161-for-one stock
dividend on March 12, 2002. Accordingly, the stockholders of the Predecessor
Company exchanged 5,212,500 shares of the Predecessor Company's common stock
for 4,648,220 shares of IDDS common stock. Prior to the merger, IDDS had
outstanding 5,080,717 shares of common stock. At the time the merger closed on
September 22, 2000, the only asset held by IDDS was a licensing agreement with
West Pharmaceutical Services, Inc. (see Note 7) executed on August 25, 2000.
IDDS was incorporated on April 8, 1999, however, it remained dormant until
executing the merger and licensing agreements noted above. The Predecessor
Company's Board of Directors and management assumed similar roles in the
Company after the merger closed. For financial reporting purposes, the merger
was accounted for as the acquisition of a licensing agreement by the
Predecessor Company and a reorganization with the Company becoming the
surviving entity. Consequently, the assets, liabilities and historic operating
results of the Company prior to the merger are those of the Predecessor
Company. The fair value of the licensing agreement was determined to be
approximately $18.6 million based on the fair value of the common stock
issued. The rights obtained under the licensing agreement related to an
unproven technology that would require significant research and development
effort

                  Notes to Financial Statements -- (Continued)

to commercialize a product. There is also a significant uncertainty as to
whether the research and development effort will be successful. Since the
licensed technology has no alternative future use, the fair value of the
consideration issued to obtain the licensing agreement was expensed as
research and development at the time the merger closed.

(2) Summary of Significant Accounting Policies

Revenue Recognition

   The Company has been awarded government grants from the Department of
Defense (the "DoD") and the National Institutes of Health (the "NIH"), which
are used to subsidize the Company's research and development projects
("Projects"). DoD and NIH revenue is recognized as subsidized Project costs
for each period are incurred. For the years ended December 31, 2000 and 2001,
all of the Company's research grant revenue came from the DoD and the NIH.

   Interest income is recognized as earned.

Research and Development Costs

   The Company expenses all research and development costs as incurred for
which there is no alternative future use. Such expenses include licensing and
upfront fees paid in connection with collaborative agreements.

Concentrations of Credit Risk

   Financial instruments which potentially subject the Company to
concentrations of credit risk consist of cash, cash equivalents, and
receivables from the DoD and the NIH. The Company has established guidelines
that relate to credit quality and diversification and that limit exposure to
any one issue of securities.

Fixed Assets

   Furniture and fixtures, and computer equipment are stated at cost.
Furniture, fixtures, and computer equipment are depreciated on a straight-line
basis over their estimated useful lives. Expenditures for maintenance and
repairs which do not materially extend the useful lives of the assets are
charged to expense as incurred. The cost and accumulated depreciation of
assets retired or sold are removed from the respective accounts and any gain
or loss is recognized in operations. The estimated useful lives of fixed
assets are as follows:



                                                   
                  Furniture and fixtures...........   5 years
                  Computer equipment...............   3 years



Patents

   As a result of research and development efforts conducted by the Company, it
has applied, or is applying, for a number of patents to protect proprietary
inventions. All costs associated with patents are expensed as incurred.

Cash and Cash Equivalents

   The Company considers all highly liquid investments which have maturities of
three months or less, when acquired, to be cash equivalents. The carrying
amount reported in the balance sheet for cash and cash equivalents
approximates its fair value. Cash and cash equivalents subject the Company to
concentrations of

                                      F-8

                     INNOVATIVE DRUG DELIVERY SYSTEMS, INC.
                        (A Development Stage Enterprise)

                  Notes to Financial Statements -- (Continued)

credit risk. At December 31, 2001 and 2000, the Company had invested
approximately $7.7 million and $10.1 million, respectively, in funds with a
single commercial bank.

Net Loss Per Share

   The Company prepares its per share data in accordance with Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS No. 128").
Basic net loss per share is computed on the basis of net loss for the period
divided by the weighted average number of shares of common stock outstanding
during the period. Since the Company has incurred net losses since inception,
diluted net loss per share does not include the number of shares issuable upon
exercise of outstanding options and warrants and the conversion of preferred
stock since such inclusion would be anti-dilutive. Disclosures required by
SFAS No. 128 have been included in Note 8.

Pro Forma Financial Information (unaudited)

   As discussed further in Note 5, all outstanding shares of Series A
redeemable convertible preferred stock ("Series A stock") and Series B stock
will automatically convert into 5,084,900 shares of common stock upon the
closing of an initial public offering of the Company's common stock as
defined. The pro forma balance sheet at December 31, 2001, assumes that the
historical balance sheet is adjusted to reflect the conversion of Series A
stock and Series B stock into common stock as if it had occurred on December
31, 2001. The pro forma net loss per share data presented within the Statement
of Operations for the year ended December 31, 2001 assumes that the historical
per share data computed in accordance with SFAS No. 128 is adjusted to reflect
the conversion of all outstanding shares of Series A stock and Series B stock,
on a weighted average basis, as if such conversion had occurred on the dates
of issuance (September 22, 2000 and December 31, 2001, respectively). Pro
forma net loss per share data for the years ended December 31, 1999 and 2000
have been intentionally omitted.

Deferred Financing Costs

   Costs incurred in connection with issuance of notes payable are deferred and
amortized using the interest method, which approximates the straight-line
method, as interest expense over the term of the debt instrument.

Income Taxes

   The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS No. 109"). SFAS No. 109 requires that the Company recognize
deferred tax liabilities and assets for the expected future tax consequences
of events that have been included in the financial statements or tax returns.
Under this method, deferred tax liabilities and assets are determined on the
basis of the difference between the tax basis of assets and liabilities and
their respective financial reporting amounts ("temporary differences") at
enacted tax rates in effect for the years in which the temporary differences
are expected to reverse.

Comprehensive Loss

   Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income", established standards for reporting and display of
comprehensive loss and its components in the financial statements.
Implementation of this statement has not had an impact on the Company's
financial statements as the Company has no other comprehensive items to report
other than net loss.

                        (A Development Stage Enterprise)

                  Notes to Financial Statements -- (Continued)

Impairment of Long-Lived Assets

   In accordance with the provisions of Statement of Financial Accounting
Standards No. 121, "Accounting for Impairment of Long-Lived Assets and Long
Lived Assets to be Disposed Of" ("SFAS 121") long-lived assets are reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. If the sum of the expected future
undiscounted cash flows is less that the carrying amount of the asset, a loss
is recognized for the difference between the fair value and carrying value of
the asset. For all periods presented there have been no impairment losses
incurred.

Equity Issuance Costs

   Costs associated with the issuance of the Company's common or preferred
stock are initially recorded as prepaid offering costs. Upon issuance of the
securities, those costs are reclassified as a reduction of the offering
proceeds. In the event that the offering is not completed, those costs would
be expensed in the period the offering is determined to be unsuccessful.

Risks and Uncertainties

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Significant estimates relate to the valuation of equity
instruments issued for services rendered, recoverability of fixed assets and
deferred taxes. Actual results could differ from those estimates.

Stock-Based Compensation

   The Company accounts for stock-based compensation to employees in accordance
with APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No.
25"). Under APB No. 25, generally, no compensation expense is recognized in
the financial statements in connection with the awarding of stock option
grants to employees provided that, as of the grant date, all terms associated
with the award are fixed and the fair value of the Company's stock, as of the
grant date, is equal to or less than the amount an employee must pay to
acquire the stock. The Company will recognize compensation expense in
situations where the terms of an option grant are not fixed or where the fair
value of the Company's common stock on the grant date is greater than the
amount an employee must pay to acquire the stock.

   Disclosures required by Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("SFAS No. 123"), including pro
forma operating results had the Company prepared its financial statements in
accordance with the fair-value-based method of accounting for stock-based
compensation, have been included in Note 9.

   The fair value of options and warrants granted to non-employees for
financing, goods or services are included in the financial statements and
expensed over the life of the debt, as the goods are utilized or the services
performed, respectively. The fair value of options and warrants issued to non-
employees has been calculated using the Black-Scholes option pricing model,
based on the following assumptions: risk free interest rate of 6%; expected
life of 5 to 7 years; zero dividend yield; and volatility of 75%.

Impact of Future Adoption of Recently Issued Accounting Standards

   The Financial Accounting Standards Board has recently issued Statement of
Financial Accounting Standards No. 141 (FAS 141), "Business Combinations" and
Statement of Financial Accounting Standards No. 142 (FAS 142), "Goodwill and
Other Intangible Assets". FAS 141 requires that all business combinations be
accounted for under the purchase method and that certain acquired intangible
assets in a

                                      F-10

                     INNOVATIVE DRUG DELIVERY SYSTEMS, INC.
                        (A Development Stage Enterprise)

                  Notes to Financial Statements -- (Continued)

business combination be recognized as assets apart from goodwill. FAS 142
requires that ratable amortization of goodwill and certain intangible assets
be replaced with periodic tests of the goodwill's impairment and that other
intangible assets be amortized over their useful lives. FAS 141 is effective
for all business combinations initiated after June 30, 2001. The provisions of
FAS 142 will be effective for fiscal years beginning after December 15, 2001
and will thus be adopted by the Company in fiscal year 2002.

   In July 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143 (FAS 143), "Accounting for Obligations
Associated with the Retirement of Long-Lived Assets." The objective of FAS 143
is to provide accounting guidance for legal obligations associated with the
retirement of tangible long-lived assets. The retirement obligations included
within the scope of this project are those that an entity cannot avoid as a
result of either the acquisition, construction or normal operation of a long-
lived asset. Components of larger systems also fall under this project, as
well as tangible long-lived assets with indeterminable lives. FAS 143 is
required to be adopted on January 1, 2003.

   The Financial Accounting Standards Board issued FASB Statement No. 144,
Accounting for the Impairment or Disposal of Long-Lived Assets. The objectives
of FAS 144 are to address significant issues relating to the implementation of
FASB Statement No. 121 (FAS 121), Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of, and to develop a single
accounting model, based on the framework established in FAS 121, for long-
lived assets to be disposed of by sale, whether previously held and used or
newly acquired. The provisions of FAS 144 are effective for financial
statements issued for fiscal years beginning after December 15, 2001.

   Management believes that the future adoption of these accounting standards
will not have a material impact on the Company's financial statements.

   Fixed assets consist of the following:

   The Company has agreements to spend approximately $4.7 million for future
clinical and development programs. However, such agreements may be cancelled
upon written notice to the other party.

(5) Stockholders' (Deficit) Equity

   The Company's Certificate of Incorporation, as amended, authorizes the
Company to issue 21.5 million shares of common stock (the "Common Stock"),
$0.001 par value, and 6.5 million shares of preferred stock (the "Preferred
Stock"), $0.001 par value. The Company's Board of Directors (the "Board") has
the authority to issue preferred stock, in series, with rights and privileges
determined by the Board. The Board designated 4.5 million shares of preferred
stock as Series A stock and approximately 1.4 million shares of Preferred
Stock as Series B stock. In September 2000 and December 2001, investors
purchased 4,014,125 shares of Series A stock and 989,991 shares of Series B
stock, respectively.

   Dividends may be declared and paid on Common Stock and Preferred Stock as
determined by the Board, provided that (i) concurrently with the declaration
of dividends on Common Stock, the Company declares and pays a dividend to the
holders of Preferred Stock equal to that which would be payable to them if
their Preferred Stock had been converted into Common Stock on the date of
determination of holders of Common Stock to receive such dividend and (ii)
dividends declared on Series A stock are subject to prior rights of holders of
any superior class of stock.

   In the event of liquidation, dissolution or winding up of the Company,
holders of Series A stock will be entitled to be paid the greater of (i) $4.00
per share subject to adjustment for stock dividends, stock splits, mergers or
other recapitalization, as defined, plus all dividends accrued or declared but
unpaid, out of the assets of the Company (the "Liquidation Amount") or (ii)
the Shared Allocation Amount. The Shared Allocation Amount is that portion of
the Company's assets available for distribution to stockholders allocated
based on percentage of outstanding shares held by that class of stockholders.
The order of preference of payments will be to holders of Series A Stock and
then Common Stock.

   Each share of Series A stock is convertible into the number of shares of
Common Stock determined by dividing the Series A Conversion Price into $4.00.
The Series A Conversion Price of the Series A stock is initially $3.94 per
share adjusted for certain dilutive events, as defined. Accrued but unpaid
dividends are forfeited upon conversion of Series A stock. As of December 31,
2000 and 2001, the Series A Conversion Price was $3.94 and the outstanding
Series A stock is convertible into 4,078,927 shares of Common Stock.

   Shares of Series A stock will automatically convert into shares of Common
Stock based upon the Series A Conversion Price in effect at the time upon (i)
the closing of an initial public offering of the Company's Common Stock,
within defined terms or (ii) written election of the holders of a majority of
Series A stock.

   In the event of consolidation, merger or other reorganization of the Company
in which the Company is not the surviving entity, the holders of Series A
stock will be entitled to be paid, out of the assets of the Company available
for distribution before any payment to holders of junior stock of the Company,
the greater of (i) the Liquidation Amount or (ii) the Shared Allocation
Amount, as defined. Such payment will be made by redemption of such shares by
the Company or by the surviving company. Accordingly, the Series A stock is
presented as redeemable preferred stock.

   Holders of Series A stock have the number of votes equal to the number of
shares of Common Stock into which the shares of Series A stock convert into at
the date on which the vote is held. Holders of Common Stock have one vote per
share.

   At the option of the Company, shares of Series A stock may be redeemed at a
redemption price per share of $4.00 plus dividends accrued or declared but
unpaid (the "Redemption Price") up to and including the redemption date. The
Redemption Price is subject to adjustment for stock dividends, stock splits,
mergers or recapitalizations, as defined.

   In September 2000, the Company sold 160.565 units ("Units" or "Series A
Financing") to investors at a per Unit price of $100,000. Each Unit consisted
of 25,000 shares of Series A stock (convertible into 25,404

shares of common stock) and 2,540 warrants (the "A Preferred Warrants"). Each
A Preferred Warrant entitles the holder to purchase one share of Common Stock
at an exercise price of $3.94 per share. The A Preferred Warrants contain
certain antidilution provisions, as defined. The A Preferred Warrants expire
in October 2005. The fair value of the A Preferred Warrants at issuance was
$960,361. At December 31, 2001, none of the A Preferred Warrants had been
exercised (see Note 10).

   As partial consideration for the sale of the Units, an option to purchase
15.83 units (the "Finders Units") was issued to members of the firm
responsible for obtaining the financing. Each Finders Unit entitles the holder
to purchase 25,000 shares of Series A stock (convertible into 25,404 shares of
common stock) and 2,540 A Preferred warrants (the "Finders Warrants") for
$110,000 per Finders Unit. The fair value of the Series A stock, which was
accounted for as a cost of the Series A Financing, totaled $1,071,331. Each
Finders Warrant entitles the holder to purchase one share of Common Stock at a
per share price of $3.94. The Finders Warrants expire in September 2007. The
fair value of the Finders Warrants at the date of issue was $107,825.

   During 1999, a consultant (the "Consultant") was issued 189,496 shares of
Common Stock for services rendered and a subscription receivable of $106. The
fair value of the Consultant shares was $93,244.

   In 2000, another consultant, acting as an advisor to the Series A Financing,
received 15,242 warrants to purchase shares of Common Stock at an exercise
price of approximately $0.001 per share. The warrants expire in August, 2007.
The fair value of the warrants, which has been accounted for as a cost of the
Series A Financing, at the issuance date was $55,790. All of the warrants were
exercised in 2001.

   In December, 2001, the Company's Board of Directors designated 1,351,350
shares of preferred stock, $0.001 par value, as Series B Convertible Preferred
Stock ("Series B stock"). The Company then closed a $5.5 million private
financing consisting of the sale of 10.9887 units of Series B stock (the
"Series B Unit") at $500,000 per Series B Unit. Each Series B Unit consists of
90,090 shares of Series B stock with a stated value of $5.55 per share,
subject to adjustment for stock dividends, stock splits, mergers and
recapitalizations, as defined. The preferences and rights of Series B stock
are the same as those of Series A stock regarding conversion, redemption,
voting and liquidation of the Company, except that the stated value and the
conversion price used in calculating those preferences is $5.55 and $5.46 for
Series B stock, respectively, rather than $4.00 and $3.94 for Series A stock
respectively.  As of December 31, 2001, the Series B stock converts into
1,005,973 shares of common stock. Series B stock is considered to be
mandatorily redeemable preferred stock since it is redeemable upon events of
consolidation, merger or other reorganization of the Company.

   The Series B conversion price represented a discount from the estimated fair
value of the Common Stock at the time of issuance.  Accordingly, the discount
amount is considered incremental yield ("the beneficial conversion feature")
to the preferred stockholders and has been accounted for as a deemed dividend
to preferred stockholders. Based on the conversion terms of the Series B
stock, a deemed dividend of approximately $3.6 million has been added to the
net loss in the calculation of net loss applicable to common stockholders in
the year ended December 31, 2001.

(6) Notes Payable

   (a) During 1998, the Company issued two notes payable to two banks with
principal amounts of $145,000 and $80,000, respectively (the "Notes"). The
Notes were due in September 2000 and bear interest of 1% over the Eurodollar
rate and the bank's prime rate, respectively. The Notes were guaranteed by one
of the Company's investors. At December 31, 1999, the outstanding balances on
the Notes were $145,000 and $80,000, respectively, accrued interest totaled
$1,400 and the weighted average interest rate was 7.5%. During 2000, the
$145,000 Note was increased to $245,000. Both Notes were repaid in October
2000, following the issuance of Series A stock (see Note 5).

                  Notes to Financial Statements -- (Continued)

   (b) During 1999, the Company raised $1.04 million by issuing notes payable
(the "Bridge Notes") and warrants (the "Bridge Warrants"). The Bridge Notes
accrued interest at 12% per annum for the first twelve months and 15% per
annum for up to an additional year. At December 31, 1999, accrued interest on
the Bridge Notes was approximately $86,000. At December 31, 1999, the fair
value of the Bridge Notes approximated their face value. In November, 2000,
after issuance of Series A stock, the principal plus accrued interest totaling
approximately $1,238,000 was repaid.

   In connection with the Bridge Notes, 231,859 Bridge Warrants to purchase an
equal number of shares of Common Stock, with an exercise price of
approximately $0.01, were issued to the Bridge Noteholders. The Bridge
warrants contain anti-dilution provisions and expire in September, 2005. The
fair value of the Bridge Warrants at the date of issue was $101,564.
Accordingly, the Bridge Notes were recorded at an original issue discount of
$101,564, which was amortized to interest expense over the term of the Bridge
Notes. At December 31, 1999, the Bridge Notes were recorded at $980,256.
During the year ended December 31, 2001, Bridge Warrants to purchase 15,606
shares of common stock were exercised (see Note 10).

   Professional fees incurred in connection with the Bridge Notes, amounting to
$128,719, were accounted for as deferred financing costs.

   In 1999, three consultants, who had arranged the sale of Bridge Notes
received a total of 200,642 warrants, exercise price of approximately $0.001,
to purchase shares of Common Stock. The warrants expire in August 2007. The
fair value of the warrants, which were accounted for as deferred financing
costs, at the issuance date was $98,598. All of the warrants were exercised in
2000.

   (c) In July 2000, the Company entered into a note (the "Second Note") with
a commercial bank with principal amount of $150,000 and bearing interest,
payable monthly, based on the Eurodollar rate plus 1% due in July, 2001. The
Second Note was guaranteed by one of the Company's investors. In October 2000,
following the closing of the sale of Series A stock, the Second Note was
repaid.

   Notes payable transactions are summarized as follows:



                                                                       Notes     Bridge Note    Second Note       Total

(7) Commitments and Contingencies

Research Collaboration, Licensing and Consulting Agreements

   (a) As part of the formation of the Company, the Company entered into a
license agreement with Stuart Weg, M.D. The license granted the Company
exclusive worldwide rights, including the right to grant

                                      F-14

                     INNOVATIVE DRUG DELIVERY SYSTEMS, INC.
                        (A Development Stage Enterprise)

                  Notes to Financial Statements -- (Continued)

sublicenses, for the intellectual property surrounding transnasal ketamine. In
connection therewith, the Company made an upfront payment to Dr. Weg, Herbert
Brotspies, and Calgar & Associates (collectively the "Founders") and issued
the Founders shares of Common Stock, of which a portion is held in escrow and
will be released to the Founders, if at all, upon the successful completion of
the Phase III trial. The issuance of the shares from escrow is not contingent
on the Founders' performance. The Company also reimbursed the Founders for
patent and other costs. The Company will pay semi-annual royalty payments to
the Founders based on a percentage of net sales of transnasal ketamine by the
Company or its sublicensees. In addition, the Company shall pay the Founders a
defined percentage of all sublicensing fees or other lump sum payments. The
Company is also obligated to make aggregate future payments of approximately
$1.3 million upon the earlier of certain defined dates ranging from August
2003 to November 2004 or satisfaction of certain clinical and regulatory
milestones, which includes the filing of a New Drug Application ("NDA") with
the Food & Drug Administration ("FDA"), the approval of an NDA by the FDA and
the first commmercial sale of a licensed product. A defined percentage of such
milestone payments shall be creditable against royalties earned; provided,
however, that in no event shall royalties earned be reduced by more than a
certain percentage in any applicable semi-annual period. The Company may
satisfy a portion of the milestone payments through the issuance of shares of
Common Stock of the Company; provided that the Company is publicly traded at
the time such milestone payment accrues.

   In connection with the above license agreement, in February 1998 the Company
entered into a three year Consulting Agreement, renewable upon mutual consent,
with each of Dr. Weg and Herbert Gary. Pursuant to such Consulting Agreements,
both Dr. Weg and Mr. Gary will provide the Company with such consulting
services as the Company may reasonably request. In consideration for such
services the Company has agreed to pay to each of Dr. Weg and Mr. Gary a
consulting fee equal to $75,000 per year, payable in equal monthly
installments. These agreements expired March 2001 and were not renewed.

   (b) On August 25, 2000, the Company entered into a license agreement with
West Pharmaceutical Services, Inc. ("West") for rights to develop and
commercialize intranasal morphine, fentanyl and other products. Under the
terms of the agreement, the Company was granted an exclusive, worldwide,
royalty bearing license, including the right to grant sublicenses, for the
rights to the intellectual property covering these products. The license
agreement will expire with the last to expire of the license patents in 2016.
In consideration of the license, the Company paid and expensed on September
22, 2000 an up front fee. In addition, under the license agreement for
morphine, fentanyl and other products the Company is obligated to make royalty
payments to West based upon net sales of products by the Company or its
sublicensees, if any, as defined. The Company is also obligated to pay West a
minimum annual royalty for each licensed product that receives approval by a
regulatory agency to be marketed in any major market country, as defined. The
Company is also obligated to pay West a defined amount of any up-front license
fees in the event that the Company sublicenses any rights to any third party.
In addition, under a Development Milestone and Option Agreement entered into
by the Company and West in connection with the license agreement, the Company
is obligated to make aggregate future payments totaling $5.0 million upon
reaching certain defined development milestones, which includes the filing of
an NDA with the FDA, the approval of an NDA by the FDA of a licensed product.
Milestone payments can be paid in cash or equity upon the satisfaction of
certain clinical and regulatory milestones and provided that the Company is
publicly traded at the time such milestone payment accrues. The Company's
ability to pay the upfront payment for the license agreement and the M-6-G fee
(see below) was guaranteed by an affiliate of the Company. The guarantee
expired upon the payments by the Company of amounts owed to West. In addition,
the Company granted West the right of first refusal to enter into a clinical
manufacturing agreement for nasal morphine (see c. (i), below).

   The license agreement and related agreements (see c. (i) to c. (iv) below)
may be terminated by mutual consent of the parties at any time or by either
party upon written notice of default, including non-performance, by the other
party that is not cured within 30 days.

                  Notes to Financial Statements -- (Continued)

   (c) In connection with the West license agreement, the Company entered into
the following additional agreements:

      (i) A clinical manufacturing agreement, whereby the Company will buy
   from West 100% of the nasal morphine product required for conducting the
   clinical trials subject to West's ability to supply 100% of the required
   product. West will manufacture and package the clinical product for the
   Company. This agreement will be in effect until the earlier of (a) a period
   of 2 years or (b) the last to occur launch date after the clinical product
   has been launched in all major market countries.

      (ii) An option agreement, whereby the Company was granted an option to
   include morphine -6- glucuronide ("M-6-G") as an identified compound under
   the license agreement. The Company paid and expensed a non-refundable fee in
   consideration of the option, which expired unexercised on December 22, 2000.

      (iii) On October 24, 2000, the Company expanded its license agreement to
   include an additional development agreement with West for rights to develop
   and commercialize intranasal fentanyl. The Company will undertake a
   development program for intranasal fentanyl with West. The parties will
   endeavor to complete the development program within the defined time table.
   However, the Company can use other suppliers should West be unable to either
   provide competitive cost bids or complete the program within a reasonable
   timeframe. In addition, under the development agreement, the Company is
   obligated to make aggregate future payments totaling $6.3 million upon
   reaching certain defined development milestones, which includes completion
   of proof-of-principle studies, successful completion of a phase I/II
   clinical trial, commencement of a phase III clinical trial, filing of an NDA
   with the FDA and the approval of an NDA by the FDA of a licensed product.
   These milestone payments can be paid in cash or equity upon the satisfaction
   of certain clinical and regulatory milestones and provided that the Company
   is publicly traded at the time such milestone payment accrues.

      (iv) On November 17, 2000, the Company entered into a clinical
   manufacturing agreement with West to manufacture, package, purchase and sell
   to the Company nasal ketamine clinical product according to agreed upon
   clinical product specifications and price schedule. The agreement terminated
   in November 2001.

   (d) On December 14, 2001 (the "Effective Date"), the Company entered into
an agreement (the "Shimoda Agreement") with Shimoda Biotech (Proprietary) Ltd.
and certain affiliated entities ("Shimoda"), for an exclusive worldwide
license to commercialize formulations of pharmaceutical products containing
diclofenac. The Company will pay: (i) a license fee to Shimoda and
reimbursement for expenses, if certain defined events occur; (ii) two percent
of the net proceeds, as defined, of the Company's initial public offering to
Shimoda, but not less than $1 million or in excess of $2 million; (iii)
aggregate future milestone payments of $6.0 million payable upon the
satisfaction of certain clinical and regulatory milestones which includes
submission of an NDA with the FDA, approval of an NDA by the FDA and one year
following the date of first sale of a licensed product; and  (iv) royalty
payments to Shimoda based upon the sales of products by the Company or its
sublicensees, if any, as defined. Upon achievement of a milestone, Shimoda has
the option to receive payment in cash or shares of common stock. In the event
Shimoda elects to receive common stock, the number of shares to be issued is
based on a formula whereby the defined milestone payment is divided by the per
share price of the Company's common stock in an initial public offering as
defined.  Should common stock be issued in satisfaction of milestones, the
Company will record a non-cash charge based on the fair value of the
consideration paid at the date the milestone is achieved. Such charge could be
material and could result in a material dilution to per share amounts. The
Shimoda Agreement may be terminated (i) by either party due to breach by the
other party that is not cured within 60 days of written notice; (ii) by
Shimoda in the event of default by the Company for non-payment of amounts due
that is not cured with 60 days of written notice; (iii) by the Company, if
certain defined initial activities are not

                                      F-16

                  Notes to Financial Statements -- (Continued)

completed by Shimoda within 90 days of the Effective Date, in which case all
payments to Shimoda other than the initial payment will be refunded to the
Company or (iv) by the Company at any time by giving 90 days written notice to
Shimoda.

(8) Net Loss per Share

   The Company's basic net loss per share amounts have been computed by
dividing net loss by the weighted-average number of common shares outstanding
during the period. For all periods presented, the Company reported a net loss
and, therefore, common stock equivalents were not included since such
inclusion would have been anti-dilutive. In addition, for all periods
presented, 222,937 shares of Common Stock were held in escrow and have been
excluded from the calculation of basic and diluted earnings per share.

   The calculation of net loss per share, basic and diluted, is as follows:



                                                                                                            Weighted

(9) Stock Incentive Plan

   In February 2001, the Board and stockholders approved the adoption of the
2000 Omnibus Stock Incentive Plan (the "Plan"). Under the Plan, subject to
Board and stockholder approval of certain amendments, the Plan will provide
for the issuance of 3,556,502 shares of Common Stock to be awarded to

                                      F-17

                     INNOVATIVE DRUG DELIVERY SYSTEMS, INC.
                        (A Development Stage Enterprise)

                  Notes to Financial Statements -- (Continued)

employees, consultants, directors and other individuals who render services to
the Company (collectively, "Awardees"). The number of shares of common stock
reserved for issuance under the Plan will automatically increase on the first
trading day in January of each calendar year, beginning in calendar year 2003,
by an amount equal to 5% of the total number of shares of Common Stock
outstanding on the last trading day in December of the preceding calendar
year, but in no event will any annual increase exceed a defined number of
shares. Awards include options, restricted shares, bonus shares, stock
appreciation rights and performance shares (the "Awards"). The Plan contains
certain anti-dilution provisions in the event of a stock split, stock dividend
or other capital adjustment, as defined. The Plan includes an automatic option
grant program for non-employee directors, under which option grants will
automatically be made at periodic intervals to non-employee board members to
purchase shares of common stock as defined. The Plan provides for a Committee
of the Board of Directors (the "Committee") to grant Awards to Awardees and to
determine the exercise price, vesting term, expiration date and all other
terms and conditions of the Awards, including acceleration of the vesting of
an Award at any time. All options granted under the Plan are intended to be
non-qualified ("NQO") unless specified by the Committee to be incentive stock
options ("ISO"), as defined by the Internal Revenue Code. NQO's may be granted
to employees, consultants or other individuals at an exercise price, equal to,
below or above the fair value of the Common Stock on the date of grant. ISO's
may only be granted to employees of the Company and may not be granted at
exercise prices below fair value of the Common Stock on the date of grant
(110% of fair value for employees who own 10% or more of the Company). The
period during which an option may be exercised may not exceed ten years from
the date of grant (five years for grants of ISO's to employees who own 10% or
more of the Company). Under the Plan, for a period of one year following the
termination of an Awardee's employment or active involvement with the Company,
the Company has the right, should certain contingent events occur, to
repurchase any or all shares of Common Stock acquired upon exercise of an
Award held by the Awardee at a purchase price defined by the Plan. The Plan
will terminate at the earliest of (i) its termination by the Committee,
(ii) February 4, 2011 or (iii) the date on which all of the shares of Common
Stock available for issuance under the Plan have been issued and all
restrictions on such shares have lapsed. Awards granted before termination of
the Plan will continue under the Plan until exercised, cancelled or expired.

   As of December 31, 2001, no options have been granted under the Plan;
however, options to purchase 1,367,101 shares of the Company's common stock
have been granted outside of the Plan.

   The following table summarizes non-plan stock option information for the
options as of December 31, 2001:

(1) In addition to the above, the Committee has or has agreed to grant: 850,000
    options to three employees and 75,000 options to a related party consultant
    with an exercise price equal to that of the Company's common stock at an
    initial public offering. The Committee also agreed to grant 406,456 options
    to the Company's directors. The Committee originally intended that the
    measurement date of these options would be the date of the Company's
    initial public offering and that the options' exercise price would be equal
    to the initial public offering price. On February 25, 2002 the Committee
    granted such options fixing the exercise price at $5.46 per share. The
    exercise price is below the estimated fair value of the Company's common
    stock on the date of grant and accordingly the Company will incur a non-
    cash expense. The aggregate intrinsic value of the option grants to the
    directors at the measurement date total approximately $1.4 million. Such
    amount will be expensed over the vesting period with approximately
    $1.36 million recognized during 2002 and the balance pro rata through
    February 2003.


   Included in the options above, during the year ended December 31, 2000, the
Company granted 300,150 fully vested stock options to non-employees ("Non-
employee Options") with an average exercise price of $3.94, which are
accounted for in accordance with EITF 96-18. The estimated fair value of the
Non-employee Options on the grant date totaling $707,550 was recognized as
compensation expense in the year ended December 31, 2000.

   The following table summarizes the pro forma operating results of the
Company had compensation costs for non-plan options been determined in
accordance with the fair value based method of accounting for stock based
compensation as prescribed by SFAS No. 123. Since option grants awarded during
2000 and 2001 vest over several years and additional awards are expected to be
issued in the future, the pro forma results shown below are not likely to be
representative of the effects on future years of the application of the fair
value based method. Since no stock options were granted prior to September 1,
2000, the pro forma net loss and net loss per share for the year ended
December 31, 1999 is equal to the amount as presented in the Statement of
Operations.



                                                               Year Ended December 31,

   For the purpose of the above pro forma calculation, the fair value of each
option granted was estimated on the date of grant using the Black-Scholes
option pricing method. The weighted-average fair value of the options granted
during 2000 and 2001 was $2.39. The following assumptions were used in
computing the fair value of option grants: expected volatility of 75%,
expected life of 5 years; zero dividend yield and risk-free interest rate of
6.0%.

   The Company intends to adopt an employee stock purchase plan ("ESPP"), which
will become effective upon the completion of an initial public offering of the
Company's common stock. Under the ESPP, eligible employees may set aside up to
15% of their eligible compensation to be applied to the purchase of shares of
the Company's common stock. The per share price the employee must pay to
acquire each share of common stock will be equal to 85% of the lower of the
quoted market price of the Company's Common Stock at the start date of the
offering period or the semi-annual purchase date. The ESPP will be implemented
in a series of overlapping periods, each with a duration of 24 months. The
initial offering period will begin at the time of the initial public offering.
Subsequent offering periods will begin at 6-month intervals and each such
offering period will have 4 semi-annual purchase dates. The ESPP has been
designed to qualify as a non-compensatory plan under Section 423 of the
Internal Revenue Code. Upon completion of an initial public offering, the
Company will finalize various terms and conditions including the number of
shares of common stock available under the ESPP.

(12) Income Taxes

   There is no provision (benefit) for federal or state income taxes for the
years ended December 31, 1999, 2000 and 2001 since the Company has incurred
operating losses and has established valuation allowances equal to the total
deferred tax asset due to the uncertainty with respect to achieving taxable
income in the future.

   The tax effect of temporary differences and net operating losses as of
December 31, 2000 and 2001 are as follows:

   As of December 31, 2000 and 2001, the Company has available, for tax
purposes, unused net operating loss carryforwards of approximately $5.0
million and $12.6 million which will expire between 2018 and 2021. As of
December 31, 2001, the Company had aggregate permanent differences of $20.2
million including $18.6 million for the license acquired in connection with
the merger. Future ownership changes may limit the Company's ability to
utilize these net operating loss carryforwards as defined by the federal and
state tax codes.

Item 14. Indemnification of Directors and Officers

   The Registrant's Amended and Restated Certificate of Incorporation in effect
as of the date hereof (the "Certificate") provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"),
the Registrant's directors shall not be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty as
directors of the Registrant. Under the DGCL, the directors have a fiduciary
duty to the Registrant which is not eliminated by this provision of the
Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of nonmonetary relief will remain available. In
addition, each director will continue to be subject to liability under the
DGCL for breach of the director's duty of loyalty to the Registrant, for acts
or omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by the DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws. The Registrant has obtained liability
insurance for its officers and directors.

   Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out
of their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any
other rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Registrant may fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative)
by reason of the fact that such person is or was a director or officer of the
Registrant, or is or was serving at the request of the Registrant as a
director or officer of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding.


                                      II-1

   At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of
any threatened litigation or proceeding that may result in a claim for such
indemnification.

Item 15. Recent Sales of Unregistered Securities

   Since its inception, the Registrant, including its predecessor corporation
Pain Management, Inc., has issued and sold unregistered securities in the
amounts, at the times, and for the aggregate amounts of consideration listed
as follows:

     1.   In February 1998, Pain Management, Inc. issued to its founders
          5,000,000 shares of common stock for an aggregate purchase price of
          $5,000 pursuant to stock purchase agreements between Pain Management
          and the founders.

     2.   In June 2000, the Registrant issued to its founders 5,080,717 shares
          of common stock for an aggregate purchase price of $5,000 pursuant
          to stock purchase agreements between the Registrant and the
          founders.

     3.   In September 1999, Pain Management raised approximately $1.04
          million by issuing notes payable and warrants to investors. The
          notes accrued interest at 12% per annum for the first twelve months
          and 15% per annum thereafter. In connection with the notes, Pain
          Management issued warrants to purchase 260,000 shares of common
          stock at an exercise price of $0.01 per share to noteholders. In
          November 2000, the principal and interest on the notes representing
          approximately $1,238,000 was repaid.

     4.   In September 2000, in connection with a merger with Pain Management,
          Inc., the Registrant issued 4,648,220 shares of common stock in
          exchange for 5,000,000 shares of Pain Management. In addition, the
          Registrant exchanged warrants to purchase 260,000 shares of Pain
          Management common stock with warrants to purchase 231,859 shares of
          the Registrant's common stock. In September 2001, warrants to
          purchase 15,606 shares of common stock were exercised.

     5.   During 1999, a consultant was issued 189,496 shares of the
          Registrant's common stock for services rendered. Also in 1999, three
          consultants received warrants to purchase a total of 200,642 shares
          of the Registrant's common stock at an exercise price of
          approximately $0.001. In 2000, warrants to purchase all of these
          shares were exercised. In 2000, a consultant received warrants to
          purchase 15,242 shares of the Registrant's common stock at an
          exercise price of approximately $0.001. All of the warrants were
          exercised in 2001.

     6.   In September 2000, the Registrant sold 160.565 units ("Units") to
          investors at a per Unit price of $100,000. Each Unit consisted of
          25,000 shares of series A convertible preferred stock (convertible
          into 25,404 shares of common stock) and 2,540 warrants. Each warrant
          entitles the holder to purchase one share of the Registrant's common
          stock at an exercise price of $3.94 per share. The Registrant sold,
          in the aggregate, 4,014,125 shares of series A convertible preferred
          stock (convertible into 4,078,927 shares of common stock) and
          warrants to purchase 407,893 shares of common stock for net proceeds
          of $14,898,928.

     7.   As partial consideration for the sale of the Units, an option to
          purchase 15.83 units was issued to members of the firm responsible
          for obtaining the financing. Each Unit entitles the holder to
          purchase 25,000 shares of series A convertible preferred stock
          (convertible into 25,404 shares of common stock) at a price of $4.40
          per share and warrants to purchase 2,540 shares of common stock at
          an exercise price of $3.94 per share.

     8.   The Registrant granted stock options to purchase 1,365,882, 1,219
          and 406,456 shares of common stock at exercise prices of $3.94,
          approximately $0.01 and $5.46 respectively, per share to employees,
          consultants and directors.


     9.   In December 2001, the Registrant sold 989,991 shares of series B
          convertible preferred stock (convertible into 1,005,973 shares of
          common stock) for net proceeds of $5,020,032.

    10.   The Registrant has or has agreed to grant 850,000 options to three
          employees and 75,000 options to a related party consultant with an
          exercise price equal to that of the Registrant's common stock at the
          initial public offering.


   No underwriters were engaged in connection with the foregoing sales of
securities. Such sales of common stock, Preferred Stock and warrants were made
in reliance upon the exemption from registration set forth in Section 4(2) of
the Securities Act of 1933 and Rule 506 of Regulation D promulgated thereunder
for

                                      II-2

transactions not involving a public offering, and all purchasers were
accredited investors as such term is defined in Rule 501(a) of Regulation D.
Issuances of options to the Registrant's employees, directors and consultants
were made pursuant to Rule 701 promulgated under the Securities Act of 1933.

Item 17. Undertakings

   The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

   The undersigned Registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act
   of 1933, the information omitted from the form of prospectus filed as part
   of this registration statement in reliance upon Rule 430A and contained in a
   form of prospectus filed by the Registrant pursuant to Rule 424 (b) (1) or
   (4) or 497 (h) under the Securities Act of 1933 shall be deemed to be part
   of this registration statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Securities
   Act of 1933, each post-effective amendment that contains a form of
   prospectus shall be deemed to be a new registration statement relating to
   the securities offered therein, and the offering of such securities at that
   time shall be deemed to be the initial bona fide offering thereof.


                                      II-4

                                   SIGNATURES

Registrant has duly caused this Amendment No. 3 to the Registration Statement
to be signed on its behalf by the undersigned, thereunto duly authorized, in
the City of New York, State of New York, on April 11, 2002.
