except where we indicate otherwise, we present information in this prospectus
assuming that the underwriters do not exercise their over-allotment option.

Our Business

We are a pharmaceutical development company committed to building a portfolio
of products with significant commercial potential in select therapeutic areas.
Our initial area of focus is migraine, where we have built a portfolio of four
product candidates through a combination of innovation and in-licensing. Our
lead product candidate is MT 100, which we are developing as an oral first-line
therapy for the treatment of migraine. In December 1999, we completed our
initial Phase 3 clinical trial of MT 100. We are currently conducting three
Phase 3 clinical trials of MT 100, and we intend to initiate three additional
Phase 3 clinical trials of MT 100 by year end. In addition to our MT 100
trials, we expect to begin two additional Phase 3 or Phase 2 clinical trials
for two of our other migraine product candidates by the end of 2000. Our
portfolio of migraine product candidates is designed to address all segments of
the migraine market.

Migraine is characterized by recurring attacks of headache that are often
accompanied by visual, auditory or stomach disturbances. The average migraine
patient experiences attacks throughout his or her adult life. Migraine attacks
typically vary in severity. A variety of oral, injectable and intranasal
therapies are currently used to treat migraine attacks. We estimate that global
sales of prescription pharmaceuticals for the treatment of migraine will exceed
$2 billion by 2001. Triptans are the family of drugs most commonly prescribed
for the treatment of migraine attacks, representing, according to statistics
from IMS Health's Retail and Provider Perspective, approximately $1.1 billion
of sales in the U.S. in 1999. Although triptans can be effective in treating
migraine, they have several significant side effects, including potentially
fatal cardiac events. In addition, patients treated with triptans often do not
achieve sustained pain relief. We are developing a portfolio of product
candidates that we believe should overcome many of the limitations of currently
available migraine therapies.

MT 100 is our proprietary product candidate that combines metoclopramide
hydrochloride, a commercially available agent that relieves nausea and enhances
gastric emptying, and naproxen sodium, a commercially available anti-
inflammatory and analgesic agent. To date, more than 1,500 patients have
received MT 100 in Phase 2 and Phase 3 clinical trials. We believe data from
these trials indicate that MT 100 provides rapid and sustained migraine pain
relief compared to placebo and to MT 100's individual components. Furthermore,
MT 100 has been generally well tolerated. In December 1999, we completed a
1,064 patient Phase 3 clinical trial comparing the safety and efficacy of MT
100 against its individual components. We believe the results of the trial
indicate a statistically significant increase in sustained response, which was
the primary clinical trial endpoint, in patients receiving MT 100, as

                                       4
<PAGE>

compared to patients receiving the individual components of MT 100. Sustained
response is a clinical
measure that attempts to capture both speed of onset and duration of migraine
pain relief. Before seeking FDA marketing approval for MT 100, the results of
this Phase 3 trial must be confirmed by a second Phase 3 component comparison
trial, and we must also successfully complete two placebo controlled studies.
Additional toxicology and carcinogenicity studies may also be required.

We are developing MT 300 to provide safe, convenient and long-lasting pain
relief for patients needing an injectable therapy for severe migraines. MT 300
is a proprietary injectable formulation of the commercially available compound
dihydroergotamine mesylate, or DHE. In November 1998, we completed a 291
patient Phase 2 clinical trial of MT 300 comparing three dosing levels and a
placebo. In this clinical trial, MT 300 was well tolerated and at the highest
dosing level MT 300 demonstrated a statistically significant improvement in the
percentage of patients achieving sustained response when compared to placebo.
We plan to initiate an initial Phase 3 clinical trial of MT 300 by the end of
2000.

Pursuant to an agreement signed in September 1999 with F. Hoffmann-La Roche
Ltd, we are developing MT 500 for the prophylactic treatment, or prevention, of
migraine pain. MT 500 is a novel, orally active agent that blocks a type of
serotonin brain receptor thought to be involved in the initiation of migraine
attacks. The prophylactic market is currently composed of drugs that were
developed primarily for conditions other than migraine. Many of those drugs
have side effects, including fatigue, sexual dysfunction, weight gain, insomnia
and liver toxicity. We intend to initiate a Phase 2 clinical trial of MT 500 in
the first half of 2001.

We are developing MT 400 as a co-active migraine therapy, which combines the
activity of a commercially approved triptan drug with that of a commercially
approved long-acting, non-steroidal, anti-inflammatory drug. We believe that
the effective treatment of migraine requires targeted, specific and
complementary co-active therapy to achieve maximum therapeutic benefit with the
fewest side effects. We believe that MT 400 will prove to offer a faster onset
of action and a longer duration of migraine symptom relief than monotherapy
with either agent. In addition, since lower doses of the triptan components
could be used in certain MT 400 formulations relative to triptan monotherapy,
we believe that the potential risks of triptan-related side effects may also be
reduced with MT 400.

In addition to migraine, members of our management team have significant
experience developing drugs for diseases of the gastrointestinal and
respiratory tracts, oncology and infectious diseases. We intend to leverage our
development expertise in these therapeutic areas, as well as in migraine, to
become a leading pharmaceutical development company. The principal elements of
our strategy are to:

  .develop and commercialize our portfolio of migraine product candidates;

  .build a product pipeline through innovation, in-licensing and acquisition;

  .form collaborations for the commercialization of our product candidates;
  and

  .leverage our development effort through strategic outsourcing.

                                  RISK FACTORS

You should carefully consider the following risk factors before you decide to
buy our common stock. If any of these risks actually occur, our business
prospects, financial condition, operating results or cash flows could be
materially adversely affected. This could cause the trading price of our common
stock to decline, and you may lose part or all of your investment.

                         Risks Related to Our Business

We depend heavily on the success of our lead product candidate, MT 100, which
is still in clinical trials and may never be approved for commercial use. If we
are unable to develop, gain approval of or commercialize MT 100, our business
and results of operations will be harmed.

We have invested a significant portion of our time and financial resources
since our inception in the development of MT 100 and anticipate that for the
foreseeable future our ability to achieve profitability will be dependent on
its successful development, approval and commercialization. Many factors could
negatively affect the success of our efforts to develop and commercialize MT
100, including:

    .  negative, inconclusive or otherwise unfavorable results from our
       toxicology or carcinogenicity studies or from our clinical trials;

    .  an inability to obtain, or delay in obtaining, regulatory approval
       for the commercialization of MT 100;

    .  an inability to establish collaborative arrangements with third
       parties for the manufacture and commercialization of MT 100, or any
       disruption of any of these arrangements, if established;

    .  a failure to achieve market acceptance of MT 100;

    .  significant delays in our ongoing clinical trials and toxicology
       studies; and

    .  significant increases in the costs of our clinical trials and
       toxicology studies.

We have incurred losses since inception and anticipate that we will incur
continued losses for the foreseeable future. We do not have a current source of
product revenue and may never be profitable.

We have incurred losses in each year since our inception and we currently have
no source of product revenue. As of March 31, 2000, we had an accumulated
deficit of approximately $26.2 million. We expect to incur significant and
increasing operating losses and do not know when or if we will generate product
revenue. We expect that the amount of our operating losses will fluctuate
significantly from quarter to quarter as a result of increases and decreases in
development efforts, the timing of payments that we may receive from others,
and other factors. Our ability to achieve profitability is dependent on a
number of factors, including our ability to:

    .  develop and obtain regulatory approvals for our product candidates;

    .  receive upfront and milestone payments;

    .  successfully commercialize our product candidates, which may include
       entering into collaborative agreements for product development and
       commercialization; and

    .  secure contract manufacturing and distribution services.

We do not know if we will complete our product development efforts, receive
regulatory approval of any of our product candidates or successfully
commercialize any approved products. As a result, we are unable to predict the
extent of any future losses or when, if ever, we will achieve profitability.

                                       8
<PAGE>

None of our product candidates is approved for commercial use or sale. If we
are unable to obtain regulatory approval of our product candidates, or if we
are unable to maintain regulatory compliance, we will be unable to
commercialize our product candidates, we will be unable to generate revenues
and our business and results of operations will be harmed.

Our product candidates under development are subject to extensive domestic and
foreign regulation. The FDA regulates, among other things, the development,
testing, manufacture, safety, efficacy, recordkeeping, labeling, storage,
approval, advertisement, promotion, sale and distribution of pharmaceutical
products. If we market our products abroad, they are also subject to extensive
regulation by foreign governments. None of our product candidates, including MT
100, has been approved for sale in the United States or any foreign market.
Most of our product candidates are in the early stages of development. We will
need to successfully complete clinical testing and toxicology studies for each
of our product candidates, including MT 100, before submitting a New Drug
Application, or NDA, to the FDA for approval to market the product candidate.
Any NDA which we submit would require FDA approval before we could distribute
or commercialize the product candidate described in the NDA.

The regulatory review and approval process takes years, requires the
expenditure of substantial resources, involves post-marketing surveillance and
may involve ongoing requirements for post-marketing studies. All statutes,
regulations and guidelines governing the approval of our product candidates are
subject to change in the future. These changes may further increase the time or
cost of regulatory approval, limit approval or prevent it completely. Even if
we believe that our clinical data demonstrate the safety and efficacy of any of
our product candidates, regulators may disagree with us, which could delay,
limit or even prevent the approval of our product candidates. The FDA may also
require data in certain subpopulations, such as pediatric use, prior to NDA
approval, unless we can obtain a waiver to delay such a study. Further, we may
not obtain the labeling claims we believe are necessary or desirable for the
promotion of our product candidates.

Approval of a product candidate may be conditioned upon certain limitations and
restrictions as to the drug's use, or upon the conduct of further studies, and
is subject to continuous review. The FDA may also require us to conduct
additional post-approval clinical trials. The later discovery of previously
unknown problems with the product, manufacturer or manufacturing facility, may
result in restrictions on marketing or withdrawal of the product from the
market. After approval of a product candidate, we will have significant ongoing
regulatory compliance obligations, and if we fail to comply with these
requirements, we could be subject to penalties, including:

    .  warning letters;

    .  fines;

    .  product seizures;

    .  product recalls;

    .  withdrawal of regulatory approval;

    .  operating restrictions;

    .  injunctions; and

    .  criminal prosecution.

We and our contract manufacturers are required to comply with the applicable
FDA current Good Manufacturing Practices, or cGMP, regulations, which include
requirements relating to quality control and quality assurance, as well as the
corresponding maintenance of records and documentation. Further, manufacturing
facilities must be approved by the FDA before they can be used to manufacture

                                       9
<PAGE>

our product candidates, and are subject to additional FDA inspection. We or our
third-party manufacturers may not be able to comply with cGMP regulations or
other FDA regulatory requirements, resulting in delay or inability to
manufacture the products.

Labeling and promotional activities are subject to scrutiny by the FDA and
state regulatory agencies and, in some circumstances, the Federal Trade
Commission. FDA enforcement policy prohibits the marketing of approved products
for unapproved, or off-label, uses. These regulations and the FDA's
interpretation of them may impair our ability to effectively market products
for which we gain approval. Failure to comply with these requirements can
result in regulatory enforcement action by the FDA.

Problems or failures with the products of others, including our competitors,
could have an adverse effect on our ability to obtain regulatory approval for
any of our product candidates. If we have disagreements with any of our
collaborative parties as to the ownership of clinical trial results or
regulatory approvals, and the FDA refuses to recognize us as holding the
regulatory approvals necessary to commercialize our products, we may experience
delays in or be precluded from marketing products that we develop. Delays or
limitations in obtaining regulatory approvals may materially adversely affect
our business, financial condition and results of operations.

We need to conduct preclinical, toxicology and carcinogenicity studies and
clinical trials of all of our product candidates. These studies and trials are
costly, time consuming and unpredictable. Any unanticipated costs or delays in
these studies or trials, or the need to conduct additional trials, could harm
our business, financial condition and results of operations.

Seeking approval of our product candidates is subject to many risks, including
the risk that:

  .  the product candidate is found to be ineffective or unsafe;

  .  the clinical trial results for a product candidate delay or prevent
     regulatory approval; and

  .  we or our third-party manufacturers are unable to meet the cGMP
     regulations.

Generally, we must demonstrate the efficacy and safety of our product
candidates, including MT 100, before approval to market can be obtained from
the FDA. To demonstrate efficacy in a combination product candidate like
MT 100, which combines two previously approved component products, we must
demonstrate in clinical trials that it is both superior to each of its
individual components and effective for symptoms of migraine when compared to a
placebo. Generally, two successful clinical trials are required to demonstrate
that the product meets each of these standards for approval.

We will need to complete at least three additional Phase 3 studies prior to
submitting an NDA for MT 100. Based on discussions with the FDA after
completion of the initial Phase 3 trial, we believe that, in addition to
showing a statistically significant increase in patients achieving sustained
response in all of our trials, our trials comparing MT 100 to placebo must also
demonstrate that MT 100 is superior to placebo in three additional endpoints to
obtain FDA approval. These additional endpoints are nausea, sensitivity to
noise and sensitivity to light.

Additionally, the FDA may require us to complete long-term carcinogenicity
studies prior to NDA submission, which would delay the NDA submission for MT
100 and could cause at least a one year delay in commercialization.

Even if we determine that the data from these clinical trials and toxicology
and carcinogenicity studies are positive, we cannot assure you that the FDA,
after completing its analysis, will not determine that these trials should have
been conducted or analyzed differently, and thus reach a different conclusion
from that reached by us, or request that further trials or analysis be
conducted. Additional trials would likely be time-consuming and expensive.


                                       10
<PAGE>

We have other product candidates in clinical development. We must complete
significant preclinical, toxicology and carcinogenicity studies as well as
clinical trials on these product candidates before we submit marketing
applications in the United States and abroad. These studies and trials can be
very costly and time-consuming. In addition, we rely on third parties to
perform significant aspects of our studies and clinical trials, introducing
additional sources of risk into our development programs. Results from
preclinical testing and early clinical trials are not necessarily predictive of
results obtained in later clinical trials involving large scale testing of
patients in comparison to control groups.

The completion of clinical trials depends upon many factors, including the rate
of enrollment of patients. If we are unable to accrue sufficient clinical
patients during the appropriate period, we may need to delay our clinical
trials and incur significant additional costs. In addition, FDA or
Institutional Review Boards may require us to delay, restrict or discontinue
our clinical trials on various grounds, including a finding that the subjects
or patients are being exposed to an unacceptable health risk. Even if we
complete our clinical trials, we may be unable to submit an NDA to the FDA as
scheduled. Once submitted, an NDA would require FDA approval before we could
distribute or commercialize the product described in the application. Even if
we determine that data from our clinical trials and toxicology studies are
positive, we cannot assure you that the FDA, after completing its analysis,
will not determine that the trials should have been conducted or analyzed
differently, and thus reach a different conclusion from that reached by us, or
request that further trials or analysis be conducted. Additional trials would
be time consuming and expensive.

Our costs associated with our human clinical trials vary based on a number of
factors, including:

    .  the order and timing of clinical indications pursued;

    .  the extent of development and financial support from collaborative
       parties, if any;

    .  the number of patients required for enrollment;

    .  the difficulty in obtaining sufficient patient populations and
       clinicians;

    .  the difficulty of obtaining clinical supplies of our product
       candidates; and

    .  governmental and regulatory delays.

All statutes and regulations governing the conduct of clinical trials are
subject to change in the future, which could affect the cost of our clinical
trials. Any unanticipated costs or delays in our clinical studies could harm
our business, financial condition and results of operations.

Even if we obtain positive preclinical or clinical study results initially,
future clinical trial results may not be similarly positive. As a result,
ongoing and contemplated clinical testing and other studies, if permitted by
governmental authorities, may not demonstrate that a product candidate is safe
and effective in the patient population and for the disease indications for
which we believe it will be commercially advantageous to market the product.
The failure of our clinical trials to demonstrate the safety and efficacy of
our desired indications could harm our business, financial condition and
results of operations.

We depend on collaborations with third parties, which may reduce our product
revenues or restrict our ability to commercialize products.

Our ability to develop, manufacture, commercialize and obtain regulatory
approval of our existing and any future product candidates depends upon our
ability to enter into and maintain contractual and collaborative arrangements
with others. We have and intend in the future to retain contract manufacturers
and clinical trial investigators. In addition, the identification of new
compounds or product candidates for development may require us to enter into
licensing or other collaborative agreements with others, including
pharmaceutical companies and research institutions. We currently

                                       11
<PAGE>

intend to market and commercialize our products through others, which will
require us to enter into sales, marketing and distribution arrangements with
third parties. These arrangements may reduce our product revenues.

Our third party contractual or collaborative arrangements may require us to
grant rights, including marketing rights, to one or more parties. These
arrangements may also contain covenants restricting our product development or
business efforts in the future, or other terms which are burdensome to us, and
may involve the acquisition of our equity securities. Collaborative agreements
for the acquisition of new compounds or product candidates may require us to
pay license fees, make milestone payments and/or pay royalties.

We cannot be sure that we will be able to maintain our existing or future
collaborative or contractual arrangements, or that we will be able to enter
into future arrangements with third parties on terms acceptable to us, or at
all. If we fail to maintain our existing arrangements or to establish new
arrangements when and as necessary, we could be required to undertake these
activities at our own expense, which would significantly increase our capital
requirements and may delay the development, manufacture and commercialization
of our product candidates.

We are subject to a number of risks associated with our dependence on
contractual and collaborative arrangements with others:

    .  We may not have day-to-day control over the activities of our
       contractors or collaborators.

    .  Third parties may not fulfill their obligations to us.

    .  We may not realize the contemplated or expected benefits from
       collaborative or other arrangements.

    .  Business combinations and changes in the contractual or collaborative
       party's business strategy may adversely affect its willingness or
       ability to complete its obligations to us.

    .  The contractor or collaborative party may have the right to terminate
       its arrangements with us on limited or no notice and for reasons
       outside of our control.

    .  The contractual or collaborative party may develop or have rights to
       competing products or product candidates and withdraw support or
       cease to perform work on our products.

    .  Disagreements may arise regarding breach of the arrangement or
       ownership of proprietary rights.

These factors could lead to delays in the development or commercialization of
our product candidates, and disagreements with our contractors or collaborators
could require or result in litigation or arbitration, which would be time-
consuming and expensive. Our ultimate success may depend upon the success and
performance on the part of these third parties. If we fail to maintain these
relationships or establish new relationships as required, our business
prospects, financial condition and results of operations could be harmed.

We currently depend and will in the future depend on third parties to
manufacture our product candidates, including MT 100. If these manufacturers
fail to meet our requirements and the requirements of regulatory authorities,
our business, financial condition and results of operations will be harmed.

We do not have, and have no plans to develop, the internal capability to
manufacture either clinical trial or commercial quantities of products that we
may develop or are under development. We rely upon third party manufacturers to
supply us with MT 100 and our other product candidates. We are negotiating a
contract with the manufacturer of our clinical trial materials to manufacture
MT 100

                                       12
<PAGE>

commercially; however, we may not be able to reach agreement on terms agreeable
to us. Even if we are able to negotiate a commercial supply contract with our
current manufacturer, there is no guarantee that this manufacturer will be a
financially viable entity going forward. If any of the foregoing occurs, or if
our current manufacturer is unable to satisfy our requirements, and we are
required to find an alternative source of supply, there may be additional cost
and delays in product development and commercialization of our product
candidates, including MT 100.

Any third-party manufacturers that we may use must adhere to cGMP regulations,
which are enforced by the FDA through its facilities inspection program. The
facilities of any third-party manufacturers retained by us must pass a plant
inspection before the FDA will issue a pre-market approval of the product they
manufacture. The manufacture of product at these facilities will be subject to
strict quality control, testing and recordkeeping requirements. Even though we
have no current plans to do so, if we choose or are required for any reason in
the future to manufacture products internally, we have no experience in the
manufacture of pharmaceutical products for clinical trials or commercial
purposes. If we decide to manufacture products, we would also be subject to the
regulatory requirements described above. In addition, we would require
substantial additional capital and would be subject to delays or difficulties
encountered in manufacturing pharmaceutical products. Regardless of the
manufacturer of our products, we will be subject to continuing obligations
regarding the submission of safety reports and other post-market information.

If we encounter delays or difficulties with contract manufacturers, packagers
or distributors, market introduction and subsequent sales of our products could
be delayed. In addition, we may need to seek alternative sources of supply. If
so, we may incur additional costs or delays in product commercialization. If we
change the source or location of supply or modify the manufacturing process for
our product candidates or products, regulatory authorities, including the FDA,
will require us to demonstrate that the product produced by the new source or
from the modified process is equivalent to the product used in any clinical
trials that we had conducted. In order to demonstrate this to the FDA, we will
likely be required to conduct further studies which would result in additional
costs and would also likely result in delay of market introduction and
subsequent commercial sales of our products, and harm our business.

We do not have marketing or sales experience or capabilities.

We intend to enter into agreements with third parties to market and sell any of
our product candidates approved by the FDA for commercial sale. We may not be
able to enter into marketing and sales agreements with others on terms
acceptable to us, if at all. To the extent that we enter into marketing and
sales agreements with others, our revenues, if any, will be effected by the
sales and marketing efforts of others. We may also retain the right, where
possible, to co-promote our products in conjunction with our collaborative
parties. If we are unable to enter into third-party sales and marketing
agreements, or if we are exercising our rights to co-promote a product, then we
will be required to develop internal marketing and sales capabilities. We may
not successfully establish marketing and sales capabilities or have sufficient
resources to do so. If we fail to establish marketing and sales capabilities or
enter into marketing agreements with third parties, our business, financial
condition and results of operations may be harmed.

We face intense competition and rapid technological change.

We are engaged in a rapidly changing and highly competitive field. Other
products and therapies that currently exist or are being developed will compete
with the product candidates which we are seeking to develop and market.

A variety of oral, injectable and intranasal therapies are used to treat
different types of migraine attacks. Many patients use a personal, individually
developed, step-care approach to their attacks.

                                       13
<PAGE>

Attacks are often treated initially with simple over-the-counter analgesics,
particularly if the patient is unable to determine if the attack is a migraine
or some other type of headache. If over-the-counter remedies are unsuccessful,
patients often turn to more potent prescription drugs, including triptans,
narcotics and drugs containing analgesic/narcotic combinations. Our product
candidates will have to compete with all of these therapies.

There are numerous competitors working on products to treat migraine and the
other diseases and conditions for which we may seek to develop products in the
future. Developments by competitors may render our product candidates or
technologies obsolete or non-competitive. We face, and will continue to face,
intense competition from other companies for collaborations with pharmaceutical
companies, establishing relationships with academic and research institutions,
and licenses to proprietary technology. These competitors, either alone or with
collaborative parties, may succeed with technologies or products that are more
effective than any of our current or future technologies or products. Many of
our actual or potential competitors, either alone or together with
collaborative parties, have substantially greater financial resources, and
almost all of our competitors have larger numbers of scientific and
administrative personnel than we do. Many of these competitors, either alone or
together with their collaborative parties, also have significantly greater
experience than we do in:

    .  developing product candidates;

    .  undertaking preclinical testing and human clinical trials;

    .  obtaining FDA and other regulatory approvals of product candidates;
       and

    .  manufacturing and marketing products.

Accordingly, our actual or potential competitors may succeed in obtaining
patent protection, receiving FDA approval or commercializing products before we
do. If commercial product sales of our product candidates commence, we will be
competing against companies with greater marketing and manufacturing
capabilities, areas in which we have limited or no experience.

We also face, and will continue to face, competition from academic
institutions, government agencies and research institutions.

We depend on patents and proprietary rights. If we are unable to protect our
patents or proprietary rights, or if we are unable to operate our business
without infringing the patents and proprietary rights of others, our business,
financial condition and results of operations will be harmed.

The pharmaceutical industry places considerable importance on obtaining patent
and trade secret protection for new technologies, products and processes. Our
technology will be protected from unauthorized use by others only to the extent
that it is covered by valid and enforceable patents or effectively maintained
as trade secrets. As a result, our success depends in part on our ability to:

    .  obtain patents;

    .  license technology rights from others;

    .  protect trade secrets;

    .  operate without infringing upon the proprietary rights of others; and

    .  prevent others from infringing on our proprietary rights.

We cannot be certain that our patents or patents that we license from others
will be enforceable and afford protection against competitors. The patent
positions of pharmaceutical companies are highly uncertain and involve complex
legal and factual questions. Therefore, we cannot predict the breadth of claims
that will be allowed under either our patent applications or the patent
applications of our collaborative parties, or the enforceability of any
resulting patents.

                                       14
<PAGE>

Our patents or patent applications, and those of our collaborative parties,
issued or pending, respectively, may be challenged, invalidated or
circumvented. Our patent rights may not provide us with proprietary protection
or competitive advantages against competitors with similar technologies. Others
may independently develop technologies similar to ours or independently
duplicate our technologies. Due to the extensive time required for development,
testing and regulatory review of our potential products, our patents may expire
or remain in existence for only a short period following commercialization.
This would reduce or eliminate any advantage the patents may give us.

We cannot be certain that we were the first to make the inventions covered by
each of our issued or pending patent applications or that we were the first to
file patent applications for such inventions. We may need to license the right
to use third-party patents and intellectual property to continue development
and marketing of our product candidates. We may not be able to acquire such
required licenses on acceptable terms, if at all. If we do not obtain such
licenses, we may need to design around other parties' patents, or we may not be
able to proceed with the development, manufacture or sale of our product
candidates. We may face litigation to defend against claims of infringement,
assert claims of infringement, enforce our patents, protect our trade secrets
or know-how, or determine the scope and validity of others' proprietary rights.
Patent litigation is costly. In addition, we may require interference
proceedings declared by the United States Patent and Trademark Office to
determine the priority of inventions relating to our patent applications.
Litigation or interference proceedings could have a material adverse effect on
our business, financial condition and results of operations, and we could be
unsuccessful in our efforts to enforce our intellectual property rights.

We have entered into confidentiality agreements with our employees,
consultants, contractors, advisors and collaborators. However, these parties
may not honor these agreements and we may not be able to successfully protect
our rights to unpatented trade secrets and know-how. Others may independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to our trade secrets and know-how. Many of our scientific
and management personnel were previously employed by competing companies. As a
result, such companies may allege trade secret violations and similar claims
against us.

Our business strategy depends on our ability to identify and acquire product
candidates or approved products.

As part of our business strategy we plan to identify and acquire product
candidates or approved products in areas in which we possess particular
knowledge. If we fail to acquire, develop and commercialize additional products
or product candidates, or fail to promote or market commercially successful
products, our future business and results of operations could be harmed.
Because we do not directly engage in basic research or drug discovery, we must
rely upon third parties to sell or license product opportunities to us. Other
companies, including some with substantially greater financial, marketing and
sales resources, are competing with us to acquire such products. We may not be
able to acquire rights to additional products on acceptable terms, if at all.
In addition, we may acquire new products with different marketing strategies,
distribution channels and bases of competition than those of our current
products. Therefore, we may not be able to compete favorably in those product
categories.

Any of our future products, including MT 100, may not be accepted by the
market, which would harm our business and results of operations.

Even if approved by the FDA and other regulatory authorities, our product
candidates, including MT 100, may not achieve market acceptance and we may not
receive revenues from these products as anticipated. The degree of market
acceptance will depend upon a number of factors, including:

    .  the receipt and timing of regulatory approvals;

    .  the availability of third-party reimbursement;

                                       15
<PAGE>

    .  indications for which the product is approved;

    .  rate of adoption by health care providers;

    .  rate of product acceptance by target patient population;

    .  price of product relative to alternative therapies;

    .  availability of alternative therapies;

    .  extent of marketing efforts by us and third-party distributors and
       agents;

    .  publicity regarding our products or similar products; and

    .  extent and severity of side effects as compared to alternative
       therapies.

We may not be able to successfully manufacture and market our products even if
they perform successfully in clinical trials. Furthermore, physicians or the
medical community in general may not accept and utilize any of our products.

We may not receive third-party reimbursement for any of our future products,
which may harm our results of operations.

Our ability to commercialize our product candidates successfully will depend,
in part, on the extent to which reimbursement for the costs of such products
and related treatments will be available from government health administration
authorities, such as Medicare and Medicaid in the United States, private health
insurers and other organizations. Significant uncertainty exists as to the
reimbursement status of a newly approved health care product particularly for
indications for which there is no current effective treatment or for which
medical care is typically not sought. Adequate third-party coverage may not be
available to enable us to maintain price levels sufficient to realize an
appropriate return on our investment in product research and development. If
adequate coverage and reimbursement levels are not provided by government and
third-party payors for use of our products, our products may fail to achieve
market acceptance and our results of operations will be harmed.

Our future revenues, profitability and access to capital will be affected by
the continuing efforts of governmental and private third-party payors to
contain or reduce the costs of health care through various means. We expect a
number of federal, state and foreign proposals will seek to control the cost of
drugs through governmental regulation. We are unsure of the form that any
health care reform legislation may take or what actions federal, state, foreign
and private payors may take in response to the proposed reforms. Therefore, we
cannot predict the effect of any implemented reform on our business.

If product liability lawsuits are successfully brought against us, we may incur
substantial liabilities and may be required to limit commercialization of our
product candidates.

The testing and marketing of pharmaceutical products entails an inherent risk
of product liability. Product liability claims might be brought against us by
consumers, health care providers or by pharmaceutical companies or others
selling our future products. If we cannot successfully defend ourselves against
such claims, we may incur substantial liabilities or be required to limit the
commercialization of our product candidates. We have obtained limited product
liability insurance coverage only for our human clinical trials. However,
insurance coverage is becoming increasingly expensive, and no assurance can be
given that we will be able to maintain insurance coverage at a reasonable cost
or in sufficient amounts to protect us against losses due to liability. A
successful product liability claim in excess of our insurance coverage could
have a material adverse effect on our business, financial condition and results
of operations. We may not be able to obtain commercially reasonable product
liability insurance for any products approved for marketing.

                                       16

We may need substantial additional funding and may not have access to capital.
If we are unable to raise capital when needed, we may need to delay, reduce or
eliminate our product development or commercialization efforts, which would
harm our business.

We may need to raise additional funds to execute our business strategy. We have
incurred losses from operations since inception and we expect to incur
additional operating losses. In particular, we believe that we will require
additional capital to fund the acquisition of new product candidates. Our
actual capital requirements will depend upon numerous factors, including:

    .  the progress of our research and development programs;

    .  the progress of preclinical studies and clinical testing;

    .  the time and cost involved in obtaining regulatory approvals;

    .  the costs of filing, prosecuting, defending and enforcing any patent
       claims and other intellectual property rights;

    .  the effect of competing technological and market developments;

    .  the effect of changes and developments in our collaborative,
       licensing and other relationships; and

    .  the terms and timing of any new collaborative, licensing and other
       arrangements that we may establish.

We may be unable to raise sufficient funds to execute our business strategy.
Potential funding sources include:

    .  public and private securities offerings;

    .  debt financing, such as bank loans; and

    .  collaborative, licensing and other arrangements with third parties.

We may not be able to find sufficient debt or equity funding on acceptable
terms. If we cannot, we may need to delay reduce or eliminate research and
development programs. The sale by us of additional equity securities or the
expectation that we will sell additional equity securities may have an adverse
effect on the price of our common stock. In addition, collaborative
arrangements may require us to grant product development programs or licenses
to third parties for products that we might otherwise seek to develop or
commercialize ourselves.

We depend on key personnel and may not be able to retain these employees or
recruit additional qualified personnel, which would harm our business.

We are highly dependent on the efforts of our key management and scientific
personnel, especially John Plachetka, our President, Chief Executive Officer
and Chief Scientist. There is intense competition for qualified scientific
personnel. Since our business is very science-oriented, we need to continue to
attract and retain such people. We may not be able to continue to attract and
retain the qualified personnel necessary for developing our business. If we
lose the services of, or fail to recruit, key scientific personnel, our
business would be harmed. Furthermore, the loss of any or our key management
would harm our business. We do not maintain key man insurance for any of our
employees.

                         Risks Related to this Offering

If the market price of our common stock after this offering is lower than the
price you paid, you may not be able to sell your shares without incurring a
loss.

Prior to this offering, there has been no public market for our common stock.
If you purchase shares of our common stock in this offering, you will not pay a
price that was established in a competitive market. Rather, you will pay a
price that we negotiated with the representatives of the underwriters. After
this offering, an active trading market in our stock might not develop or
continue.

If our stock is highly volatile, the value of your investment may fluctuate
significantly.

The market prices for securities of early-stage pharmaceutical and
biotechnology companies have been particularly volatile. Some of the factors
that may cause the market price of our common stock to fluctuate include:

    .  results of preclinical studies and clinical trials conducted by us or
       on our behalf, or by our competitors;

    .  announcements of technological innovations or new commercial products
       by us, by third parties with respect to strategic relationships
       maintained with us, or by our competitors;

    .  regulatory developments in both the United States and foreign
       countries;

    .  changes in reimbursement policies;

    .  developments or disputes concerning patents or other proprietary
       rights;

    .  fluctuations in our operating results;

    .  changes in financial estimates or recommendations by security
       analysts;

    .  public concern as to the safety and efficacy of products developed by
       us, our collaborators or our competitors;

    .  lack of adequate trading liquidity as a public company;

    .  future sales or distributions of our common stock; and

    .  general market conditions.

In the past, following periods of volatility in the marketplace of a particular
company's securities, securities class action litigation has often been brought
against the company. We may become involved in this type of litigation in the
future. Litigation of this type is often extremely expensive and diverts
management's attention and resources.

We may allocate the net proceeds from this offering in ways which you and other
stockholders may not approve.

We will have significant flexibility in applying the net proceeds of this
offering and could use these proceeds for purposes other than those
contemplated at the time of the offering.

Existing stockholders own a large percentage of our voting stock and thus you
will have minimal influence on stockholder decisions.

Upon completion of this offering, we anticipate that our executive officers,
directors and greater than five percent stockholders, along with their
affiliates, will, in the aggregate, own approximately    % of our outstanding
common stock. As a result, such persons, acting together, will have the ability
to substantially influence all matters submitted to the stockholders for
approval, including the election and

                                       18
<PAGE>

removal of directors and any merger, consolidation or sale of all or
substantially all of our assets. These persons will also have the ability to
control our management and affairs. Accordingly, such concentration of
ownership may have the effect of delaying, deferring or preventing a change in
control, impending a merger, consolidation, takeover or other business
combination involving us or discouraging a potential acquirer from making a
tender offer or otherwise attempting to obtain control of our business, even if
such transactions would be beneficial to other stockholders.

You will incur immediate and substantial dilution of the stock value of your
shares.

The offering price of our common stock is substantially higher than the net
tangible pro forma book value per share of our outstanding common stock. As a
result, investors purchasing common stock in this offering will incur immediate
and substantial dilution in the net tangible book value of their common stock
of $  per share on a pro forma basis as of March 31, 2000. In the past, we
issued options and warrants to acquire capital stock at prices significantly
below the assumed offering price. There will be further dilution to investors
when any of these outstanding options and warrants are exercised.

Future sales of our common stock could cause the market price of our common
stock to decline.

The market price of our common stock could decline due to sales of a large
number of shares in the market after this offering or the perception that such
sales could occur, including sales or distributions of shares by our large
stockholders. These sales could also make it more difficult for us to sell
equity securities in the future.

Because our certificate of incorporation and bylaws and Delaware law contain
provisions that could discourage a takeover, the market price of our common
stock could decline.

We are subject to the Delaware anti-takeover laws regulating corporate
takeovers. These anti-takeover laws prevent Delaware corporations from engaging
in a merger or sale of more than 10% of its assets with any stockholder,
including all affiliates and associates of the stockholder, who owns 15% or
more of the corporation's outstanding voting stock, for three years following
the date that the stockholder acquired 15% or more of the corporation's stock
unless:

  .  the board of directors approved the transaction where the stockholder
     acquired 15% or more of the corporation's stock;

  .  after the transaction where the stockholder acquired 15% or more of the
     corporation's stock, the stockholder owned at least 85% of the
     corporation's outstanding voting stock, excluding shares owned by
     directors, officers and employee stock plans in which employee
     participants do not have the right to determine confidentially whether
     shares held under the plan will be tendered in a tender or exchange
     offer; or

  .  on or after this date, the merger or sale is approved by the board of
     directors and the holders of at least two-thirds of the outstanding
     voting stock that is not owned by the stockholder.

As such, these laws could prohibit or delay mergers or a change of control of
us and may discourage attempts by other companies to acquire us. These
restrictions are not, however, applicable to any of our existing stockholders.

Our certificate of incorporation and bylaws include a number of provisions that
may deter or impede hostile takeovers or changes of control or management.
These provisions include:

  .  our Board of Directors is classified into classes of directors with
     staggered three year-terms;

  .  the authority of our Board of Directors to issue up to 10,000,000 shares
     of preferred stock and to determine the price, rights, preferences and
     privileges of these shares, all without stockholder approval;

                                       19
<PAGE>

  .  all stockholder actions must be effected at a duly called meeting of
     stockholders and not by written consent;

  .  special meetings of the stockholders may be called only by the chairman
     of our Board of Directors, the chief executive officer or our Board of
     Directors;

  .  a supermajority (75%) vote of our stockholders is required to remove a
     member of our Board of Directors, and then only for cause; and

  .  no cumulative voting.

These provisions may have the effect of delaying or preventing a change of
control, even at stock prices higher than the then current price of our stock.

                                USE OF PROCEEDS

We estimate the net proceeds from the sale of      shares of common stock in
this offering will be approximately $    , after deducting the underwriting
discount and estimated offering expenses payable by us. Our net proceeds are
estimated to be approximately $    if the underwriters exercise their over-
allotment option in full.

We intend to use the net proceeds from the offering to fund the cost of
development, approval and commercialization of our product candidates, to
acquire or in-license additional product candidates and for working capital and
general corporate purposes. Although we may have discussions regarding
potential acquisitions that are complementary to our business and may use a
portion of the net proceeds for this purpose, we currently have no agreements
or commitments in this regard. We reserve the right, at the discretion of our
Board of Directors, to reallocate the use of proceeds in response to these and
other factors. Pending these uses, we intend to invest the net proceeds from
this offering in interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

We have never paid cash dividends on our common stock. We currently intend to
retain all of our futures earnings to finance the growth and development of our
business. We do not intend to pay cash dividends on our common stock in the
foreseeable future.

                                    DILUTION

Our pro forma net tangible book value as of March 31, 2000, was approximately
$   , or $   per share of common stock. Pro forma net tangible book value per
share represents the amount of our net total tangible assets less total
liabilities, divided by the number of shares of common stock outstanding. After
giving effect to the sale of the      shares of common stock offered hereby at
an assumed initial public offering price of $   per share less underwriting
discounts and estimated offering expenses, our pro forma net tangible book
value at March 31, 2000, would have been approximately $   million, or $   per
share of common stock. This represents an immediate increase in net tangible
book value of $   per share to existing stockholders and an immediate decrease
in net tangible book value of $    per share to new investors. The following
table illustrates this unaudited per share dilution to new investors:

Assuming the exercise in full of the underwriters' over-allotment option, our
adjusted pro forma net tangible book value after this offering at March 31,
2000 would have been approximately $    per share, representing an immediate
increase in pro forma tangible book value of $    per share to our existing
stockholders and an immediate dilution in pro forma net tangible book value of

Assuming the exercise in full of the underwriters' over-allotment option, the
percentage of shares held by existing shareholders would be      % of the total
number of shares of common stock to be outstanding after the offering, and the
number of shares held by new stockholders would be increased to         shares,
or      % of the total number of shares of common stock to be outstanding after
the offering.

As of March 31, 2000, there were outstanding options to acquire 1,029,583
shares of common stock, at a weighted average exercise price of $1.23 per
share, and warrants to acquire 347,327 shares of preferred stock were
outstanding, which will convert immediately prior to consummation of this
offering into warrants to acquire 347,327 shares of common stock, at a weighted
average exercise price of $2.28 per share.

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

You should read the following discussion of the financial condition and results
of operations in conjunction with our financial statements and the notes to
those financial statements included elsewhere in this prospectus.

Overview

We are a pharmaceutical company engaged in the development of products in
targeted therapeutic areas. Since our inception in 1996, our business
activities have primarily been associated with the development and acquisition
of four pharmaceutical product candidates. Our lead product candidate is MT
100, an orally delivered therapeutic in Phase 3 clinical trials for the
treatment of migraine. To date, we have devoted substantially all our resources
to the research and clinical development of MT 100 and of MT 300, our
injectable product candidate for severe migraine that is intended to begin
Phase 3 trials by the end of 2000. Our other migraine therapeutic product
candidates include MT 500, a migraine prophylactic, and MT 400, an orally
delivered co-active therapy. Specifically, our business activities have
included:

    .  product candidate research and development;

    .  designing and funding clinical trials for our product candidates;

    .  regulatory and clinical affairs;

    .  intellectual property prosecution and expansion; and

    .  business development including product acquisition or in-licensing.

We have incurred significant losses since our inception and we have not
generated any revenue. As of March 31, 2000, our accumulated deficit was
$26,232,582. Our historical operating losses have resulted principally from our
research and development activities, including Phase 3 and Phase 2 clinical
trial activities for our product candidates MT 100 and MT 300, respectively,
and general and administrative expenses. We expect to continue to incur
operating losses over the next several years as we complete our MT 100 clinical
trials, apply for regulatory approval, continue development of our other
migraine therapeutic product candidates, and acquire and develop product
portfolios in other therapeutic areas. Our results may vary depending on many
factors, including:

    .  the progress of MT 100 and MT 300 in the regulatory process;

    .  the acceleration of our other product candidates in the regulatory
       process;

    .  the establishment of collaborations for the development and
       commercialization of any of our migraine product candidates; and

    .  acquisition or in-licensing of other therapeutic product candidates.

Our ability to generate revenue is dependent upon our ability, alone or with
others, to successfully develop MT 100 or our other migraine product
candidates, obtain regulatory approvals and, alone or with others, successfully
manufacture and market our future products. To date, we have been dependent on
funding from the private placement of preferred stock to finance our business
activities. In March 2000, we closed a private placement of preferred stock in
which we raised net proceeds of $16,875,115 after commission and expenses.

In connection with this offering, we recorded a non-cash charge of $16,875,115
during March 2000 related to the beneficial conversion feature of the preferred
stock we sold in March 2000.


                                       26
<PAGE>

In connection with the grant of stock options to employees, we recorded
deferred compensation of $2,672,720 in the quarter ended March 31, 2000 and
$2,133,607 in the year ended December 31, 1999, respectively. These amounts
were recorded as a component of stockholders' equity and are being amortized as
charges to operations over the vesting period of the options using the straight
line method. The vesting period of the options is generally three years.
Approximately $373,000 and $168,000 of the deferred compensation was charged to
operations in the quarter ended March 31, 2000 and in the year ended December
31, 1999, respectively.

Historical Results of Operations

Three months ended March 31, 2000 compared to the three months ended March 31,
1999

Revenue: We generated no revenue during the three months ended March 31, 2000
or the three months ended March 31, 1999. In the future, we intend to generate
revenue from upfront and milestone payments connected to potential
collaborations for development and commercialization and from product royalty
revenue.

Research and Development: Research and development expenses increased 26.8% to
$2,074,132 for the three months ended March 31, 2000 from $1,635,544 for the
three months ended March 31, 1999. This net increase was primarily due to a
$509,000 increase in toxicology study costs, primarily for MT 500, a $98,000
increase resulting from additional research and development personnel costs,
partially offset by a $168,000 decrease in pharmaceutical development
activities related to MT 100. We expect research and development expenditures
to continue to increase during 2000 due to the continuation and expansion of
Phase 3 trials for MT 100 and MT 300, the commencement of the MT 400 proof-of-
concept trial, and the expansion of MT 500 pharmaceutical development and
toxicology study expenditures. Research and development expenses included the
personnel costs related to our research activities and clinical trial
preparations and monitoring expenses, and any regulatory matters.

General and Administrative: General and administrative expenses increased
164.7% to $958,945 for the three months ended March 31, 2000 from $362,322 for
the three months ended March 31, 1999 and reflects a $158,000 increase in
professional fees, travel costs and other increases related to our expanded
operational infrastructure, a $66,000 increase in personnel and related
benefits and $373,000 of amortization of deferred stock compensation. We expect
general and administrative expenditures to continue to increase during 2000 and
subsequent years due to increasing fees and expenses associated with the growth
in our market research, business development and commercialization efforts. An
expansion in general and administrative expenditures is also expected to
accompany our infrastructure growth associated with our public company
reporting activities. General and administrative expenses consisted primarily
of the costs of administrative personnel and related facility costs along with
legal, accounting and professional fees.

Interest Income, net: Interest income, net increased 58.8% to $49,075 for the
three months ended March 31, 2000 from $30,900 for the three months ended March
31, 1999. The increase is attributable to increased levels of cash and cash
equivalents available for investing in the three months ended March 31, 2000 as
compared to the three months ended March 31, 1999 primarily due to the issuance
of preferred stock in March 2000.

Year ended December 31, 1999 compared to year ended December 31, 1998

Revenue: We generated no revenue during the year ended December 31, 1999 or the
year ended December 31, 1998.

Research and Development: Research and development expenses increased 24.6% to
$9,023,320 for the year ended December 31, 1999 from $7,244,202 for the year
ended December 31, 1998. This increase was primarily due to the $352,000
increase in toxicology studies and clinical trial costs

                                       27
<PAGE>

associated with the Phase 3 clinical trial of MT 100, an increase of $427,000
in research and development personnel and benefits cost, and one-time licensing
costs.

General and Administrative: General and administrative expenses increased 64.8%
to $2,309,990 for the year ended December 31, 1999 from $1,401,285 for the year
ended December 31, 1998 and primarily reflects a $909,000 increase in personnel
and related benefits, travel costs and professional fees.

Interest Income, net: Interest income, net decreased 73.3% to $82,718 for the
year ended December 31, 1999 from $309,324 for the year ended December 31,
1998. The decrease is attributable to lower interest income offset by higher
interest expense. Interest income decreased to $219,000 for the year ended
December 31, 1999 from $345,000 for the year ended December 31, 1998 due to
lower levels of cash and cash equivalents available for investing in 1999 as
compared to 1998. Interest expense in the same periods was $136,000 and
$36,000, respectively. The increase in interest expense is primarily due to
interest paid upon the conversion of a promissory note.

Year ended December 31, 1998 compared to year ended December 31, 1997

Revenue: We generated no revenue during the year ended December 31, 1998 or the
year ended December 31, 1997.

Research and Development: Research and development expenses increased 145.6% to
$7,244,202 for the year ended December 31, 1998 from $2,949,632 for the year
ended December 31, 1997. Of this $4,294,570 increase, approximately $3,227,000
or 75% was due to increased clinical trial activities for MT 100 and MT 300.
The remaining increase was primarily due to an increase in preclinical and
clinical activities along with an increase in personnel.

General and Administrative: General and administrative expenses increased 46.8%
to $1,401,285 for the year ended December 31, 1998 from $954,307 for the year
ended December 31, 1997 primarily due to a 1998 increase in personnel and other
operational infrastructure expenses over those of the 1997 start-up period.

Interest Income, net: Interest income, net remained relatively constant at
$309,324 for the year ended December 31, 1998 compared to $315,181 for the year
ended December 31, 1997.

Income Taxes

As of March 31, 2000, we had federal and state net operating loss carryforwards
of approximately $24,000,000 and research and development credit carryforwards
of approximately $807,000. These federal net operating loss carryforwards and
research and development credit carryforwards begin to expire in 2012. State
net operating loss carryforwards begin to expire in 2001. The utilization of
the loss carryforwards to reduce future income taxes will depend on our ability
to generate sufficient taxable income prior to the expiration of the net loss
carryforwards. In addition, the maximum annual use of net loss carryforwards is
limited in certain situations where changes occur in our stock ownership.

Liquidity and Capital Resources

Since our inception, we have financed our operations and internal growth
primarily through private placements of preferred stock resulting in aggregate
net proceeds to us of $41,914,170. As of March 31, 2000, cash and cash
equivalents were $18,671,295. The majority of the proceeds raised since
inception have funded our operating activities.


                                       28
<PAGE>

Financing activities provided cash in an aggregate amount of approximately
$41,925,013 million since inception. These amounts represent the net proceeds
we received from the sale of preferred stock and common stock. In March 2000,
we closed a private placement of preferred stock financing that raised net
proceeds of $16,875,115 after commission and expenses.

Net cash used in investing activities included primarily additions of
equipment. Since inception through March 31, 2000, approximately $234,000 was
spent on equipment. We expect to continue to make purchases of equipment at
similar levels to support our expanding administrative operations.

We believe that the net proceeds from this offering, together with our current
cash balances and potential funding received from partnering license fees and
clinical development milestones will be sufficient to satisfy our anticipated
cash needs for operating expenses, working capital and capital expenditures
through the next 18 months. However, we cannot be certain that additional
funding will not be required and, if required, will be available on acceptable
terms, or at all. Further, any additional equity financing may be dilutive to
stockholders, and debt financing, if available, may involve restrictive
covenants.

Disclosure About Market Risk

Our exposure to market risk is currently confined to our cash and cash
equivalents which have maturities of less than three months, and our short-term
investments which have maturities of less than one year. We maintain an
investment portfolio of commercial paper and short-term U.S. government
securities. The securities in our investment portfolio are not leveraged, are
classified as available-for-sale and are, due to their short-term nature,
subject to minimal interest rate risk. We currently do not hedge interest rate
exposure. Because of the short-term maturities of our investments, we do not
believe that an increase in market rates would have any significant negative
impact on the realized value of our investment portfolio but may negatively
impact the interest expense associated with our long-term debt.

Recent Accounting Pronouncements

In June 1998, the FASB issued SFAS 133, "Accounting for Derivative Investments
and Hedging Activities," SFAS 133 establishes a new model for accounting for
derivatives and hedging activities and supercedes several existing standards.
SFAS 133, as amended by SFAS 137, is effective for all fiscal quarters of
fiscal years beginning after June 15, 2000. The Company does not expect that
the adoption of SFAS 133 will have a material impact on its financial
statements.

                                    BUSINESS

Overview

We are a commercially focused pharmaceutical development company committed to
building a portfolio of products in targeted therapeutic areas through a
combination of innovation and in-licensing. Our initial therapeutic focus is on
the migraine market. In December 1999, we completed the first Phase 3 clinical
trial for our lead product candidate, MT 100, which we are developing as an
oral first-line therapy for the treatment of migraine. In order to compile data
to support an NDA for MT 100, we are currently conducting three Phase 3
clinical trials of MT 100 and plan to initiate three more Phase 3 clinical
trials for MT 100 by the end of 2000. We also intend to initiate a Phase 3
trial by the end of 2000 for MT 300, which we are designing as an injectable
treatment for severe migraine attacks. Our migraine portfolio also contains one
additional product candidate for the treatment of migraine and a prophylactic
agent set to enter a Phase 2 clinical trial in the first half of 2001.

We intend to leverage our pharmaceutical product development expertise by
acquiring or in-licensing and developing commercially attractive products in
several areas outside of migraine. In addition, we plan to enter into
collaborations with established pharmaceutical companies to commercialize and
manufacture our product candidates.

Business Strategy

Our goal is to become a leading pharmaceutical development company. The
principal elements of our strategy are to:

 Develop and commercialize our portfolio of migraine product candidates

 A substantial portion of our efforts over the next few years will be devoted
 to the further development, approval and commercialization of our portfolio
 of migraine product candidates. We intend to conduct clinical trials with our
 four migraine product candidates in order to obtain marketing approvals that
 will allow us to provide therapeutic alternatives for all segments of
 migraine patients. We intend to form collaborations with established
 pharmaceutical companies for the worldwide commercialization of our migraine
 product candidates.

 Build a product pipeline through innovation, in-licensing and acquisition

 We intend to build our product pipeline through innovation, in-licensing and
 acquisition of select proprietary product candidates. We will focus primarily
 on therapeutic areas with significant commercial potential in which members
 of our management team have development expertise. These areas of expertise
 include gastrointestinal disease, respiratory disease, infectious disease and
 oncology. We plan to develop novel products that exhibit distinct advantages
 over currently marketed products, as well as innovative combinations of
 already approved products in more convenient or more therapeutically
 appropriate formulations. We plan to identify and pursue product candidates
 with the following attributes:

    .  significant commercial potential;

    .  sound scientific basis;

    .  established preclinical safety and efficacy data at a minimum;

    .  readily measurable clinical endpoints previously accepted by the FDA;

    .  clinical development timelines generally under four years; and

    .  cost-effective development programs.


                                       30
<PAGE>

 We believe pursuing product candidates with these attributes will enable us
 to develop commercially viable product candidates with lower development and
 financial risk than traditional pharmaceutical drugs.

 One of the strategies we will use to gain access to product candidates is to
 employ our license back option model. We believe this model differs from a
 traditional in-licensing arrangement in that it affords us improved access to
 commercially attractive compounds, by providing the licensor with an option
 to license back the product candidate at various stages of development and on
 set terms and conditions. We used this model to in-license our MT 500 product
 candidate from F. Hoffmann-La Roche Ltd in 1999.

 Form collaborations for the commercialization of our product candidates

 We plan to establish collaborative relationships with pharmaceutical
 companies for the commercialization of our existing and future product
 candidates. In general, we intend to license our product candidates to
 pharmaceutical companies for commercialization once we have established
 substantial evidence of safety and efficacy, at which point we believe we can
 obtain favorable economic terms. In addition, under our license back option
 model, if the licensor chooses not to license back the rights to the product
 candidate, we may pursue a collaboration with another third party for
 commercialization of the product or commercialize the product ourselves.

 Leverage development efforts through strategic outsourcing

 While maintaining overall control of the planning, development and regulatory
 processes, we seek to enter into strategic outsourcing relationships to
 develop and commercialize our product candidates in a cost-effective manner.
 We have contracted and plan to contract with third parties for product
 candidate testing, development and manufacturing.

Products Under Development

All of our migraine product candidates are being developed for the acute, or
episodic, treatment of migraine, except for MT 500, which is being developed as
a migraine prophylactic. If approved for commercial sale, all products in our
migraine portfolio will be sold by prescription. The following chart sets forth
information regarding our ongoing and currently planned clinical studies:

Migraine Market

Migraine is characterized by recurring attacks of headache, often associated
with visual, auditory or gastrointestinal disturbances. While the precise
mechanism of migraine is unknown, researchers believe migraine attacks are
caused by acute inflammation surrounding selected blood vessels in the head.
The average migraine sufferer experiences the first attack during the early
teen years, and the attacks generally continue throughout adulthood. We
estimate that global sales of prescription pharmaceuticals for the treatment of
migraine will exceed $2 billion by 2001.

                                       32
<PAGE>

Not all migraine attacks are of the same severity. Consequently, a variety of
oral, injectable and intranasal therapies are used to treat different types of
migraine attacks. Many patients use a personal, individually developed, step-
care approach to treat their attacks. Attacks are often treated initially with
simple over-the-counter analgesics, particularly if the patient is unable to
determine if the attack is a migraine or some other type of headache. If over-
the-counter remedies are unsuccessful, patients often turn to more potent
prescription drugs, including narcotics, analgesic/narcotic drug combinations
and triptans.

Currently, we are aware of no narcotics approved specifically for the treatment
of migraine. However, narcotics are prescribed outside their approved
indications to treat severe migraine attacks due to their ability to mask
migraine headache pain. The use of narcotics for the treatment of migraine has
been limited because they do not address the non-pain symptoms of migraine such
as nausea and vomiting, they can cause side effects such as drowsiness,
dizziness and constipation, and because of their potential to cause addiction.
In addition, analgesics such as acetaminophen and aspirin are generally used to
treat only mild migraine attacks, and, similarly to narcotics, do not address
the non-pain symptoms of migraines such as nausea and vomiting.

Triptans are the family of drugs most commonly prescribed for the treatment of
migraine attacks. Triptans have demonstrated the ability to constrict blood
vessels and stimulate receptors in the brain associated with migraine attacks.
Although triptans can be effective in treating migraine symptoms, they are
often associated with significant side effects and other disadvantages that
include:

    .  the occurrence of cardiovascular related events, including chest
       pain/discomfort, throat discomfort and warm/cold sensations;

    .  the potential for serious cardiovascular events, including death;

    .  difficulty in producing sustained pain relief with a single dose in a
       majority of patients;

    .  the occurrence of nausea and dizziness during treatment; and

    .  the need for cardiovascular evaluations before initially prescribing
       triptans to patients with cardiovascular disease risk factors.

Despite these shortcomings, in 1999, according to IMS Health's Retail and
Provider Perspective, or IMS, total triptan sales in the U.S. were
approximately $1.1 billion. Imitrex(R), marketed by Glaxo Wellcome, is the
dominant triptan product, with, according to IMS, total U.S. sales of
approximately $855 million in 1999. There are currently three triptan
formulations commercially available: oral, intranasal and injectable. Oral
triptans are often prescribed as a first-line treatment for migraine pain.
Intranasal triptans are often prescribed for patients requiring faster relief
than oral drugs can provide or for patients who cannot take oral medications.
For the most severe attacks, patients sometimes use an injectable form of a
triptan.

Because of the problems associated with triptans, narcotics and analgesics, we
believe an opportunity exists in all migraine therapeutic segments for products
designed to deliver an improved onset and duration of relief with reduced side
effects, especially those related to cardiovascular events.

MT 100

MT 100 is being developed as an oral first-line therapy for the treatment of
migraine pain and associated symptoms. Oral therapies are currently the most
prevalent form of migraine therapy. According to IMS, existing oral therapies
accounted for approximately $883 million in sales in the U.S. in 1999, of which
Imitrex's oral dosage form accounted for approximately $593 million.

MT 100 is a proprietary formulation that combines metoclopramide hydrochloride,
a commercially available agent that relieves nausea and enhances gastric
emptying, and naproxen sodium, a commercially available anti-inflammatory and
analgesic agent. MT 100 is designed to release a set

                                       33
<PAGE>

amount of metoclopramide hydrochloride initially, followed by a set amount of
naproxen sodium. The initial release of metoclopramide is intended to
accelerate the absorption of naproxen and to reduce nausea. Results from our
pharmacokinetic study in normal volunteers indicated that peak naproxen blood
levels were approximately 15% higher and were obtained approximately 30 minutes
faster following administration of MT 100 than with naproxen sodium alone. We
believe MT 100 may enhance the speed, effectiveness and duration of migraine
symptom relief provided by each component alone, with fewer adverse side
effects than other migraine therapies.

 MT 100 Clinical Trials

Generally, we must demonstrate the efficacy and safety of our product
candidates, including MT 100, before seeking marketing approval from the FDA.
To demonstrate efficacy in a combination product candidate like MT 100, which
combines two previously approved component products, we must demonstrate in
clinical trials that it is both superior to each of its individual components,
and more effective in treating symptoms of migraine when compared to a placebo.
Generally, the FDA requires two successful clinical trials to demonstrate that
the product candidate meets each of these standards for approval.

We have completed two Phase 2 clinical trials and one Phase 3 clinical trial
and have three Phase 3 clinical trials ongoing for MT 100. To date, more than
2,500 patients or volunteers have participated in Phase 2 and Phase 3 clinical
trials with MT 100, more than 1,500 of whom have received some form of MT 100.

In August 1998, we completed a randomized, double-blind, placebo controlled,
Phase 2 clinical trial designed to evaluate different dose combinations of
metoclopramide hydrochloride and naproxen sodium in the treatment of migraine.
The trial involved 514 patients at 34 centers in the U.S. Patients treated in
this study remained in the physician's office for two hours after dosing and
then were discharged to record any change in symptoms for the remainder of the
24-hour study period. The results of the study indicated that the optimal dose
of MT 100 would include 16mg of metoclopramide hydrochloride and 500mg of
naproxen sodium. While the study was not designed to demonstrate differences
between the MT 100 combination and its components, preliminary evidence
suggested that MT 100 might represent an improvement over its components on a
sustained response basis.

Sustained response is a clinical measure used to capture both speed of onset
and duration of migraine pain relief. Sustained response is defined as:

    .  the reduction of moderate or severe pain at baseline to mild or no
       pain without the use of rescue medication at two hours; and

    .  no return to either moderate or severe pain, or the use of rescue
       medicine, over the next 22 hours.

In September 1998, we completed a randomized, double-blind, placebo controlled
Phase 2 clinical trial involving two different doses of MT 100. The 181 patient
trial was conducted at 19 centers in Germany and was similar in design to the
Phase 2 clinical trial conducted in the United States. While the study was not
designed to distinguish efficacy differences between doses, a dose-response
relationship was observed both on measures of acute relief and sustained
response.

In December 1999, we completed a 1,064 patient randomized, double-blind,
single-dose, Phase 3 clinical trial designed to compare the safety and efficacy
of MT 100 with its individual components, naproxen sodium and metoclopramide
hydrochloride, for the treatment of migraine. In contrast to the design of our
Phase 2 clinical trials in which patients were treated at the physician's
office, eligible patients in this Phase 3 clinical trial were provided a sealed
packet of study medication and a diary card. At the time of their next migraine
attack, patients called their physician and were instructed to take the study
medication if their headache pain was moderate or severe, and to record
migraine symptoms for 24 hours after ingesting the dose.

                                       34
<PAGE>

The primary efficacy endpoint for this Phase 3 trial was sustained response.
Using the statistical analysis methodology specified in the trial protocol, MT
100 demonstrated superiority over only one of its two components. However,
statistical significance in favor of MT 100 over both components was
demonstrated when the results of this trial were analyzed using an ordered
logistic regression, which was a refinement of the primary analysis method of
logistic regression that was originally specified in the protocol.

The ordered logistic regression analysis of this trial indicated that the
percentage of patients that achieved the primary endpoint of sustained response
using MT 100 was a statistically significant 19% greater than the percentage of
patients who achieved sustained response using naproxen sodium, and a
statistically significant 81% greater than the percentage of those using
metoclopramide hydrochloride. In addition, MT 100 demonstrated a statistically
significant benefit over its components in five out of ten secondary endpoints,
including sustained pain free for 24 hours. The secondary endpoints that did
not achieve statistical significance included relief of nausea, sensitivity to
light and sensitivity to sound.

Based on our discussions with the FDA, we have designed our planned second
Phase 3 trial comparing MT 100 to its components using ordered logistic
regression as the primary analysis method. Based on those discussions, we
believe that, if the results of this second trial are also statistically
significant based on an ordered logistic regression methodology, the FDA will
accept the initial trial results, and we will have satisfied the FDA
requirement for the successful completion of two Phase 3 clinical trials
comparing MT 100 with its components.

In the Phase 3 trial, there was no statistically significant difference in the
occurrence of adverse events for MT 100 relative to naproxen sodium or
metoclopramide hydrochloride. No single adverse event occurred from MT 100 in
more than 2.4% of the patient population. Adverse events included drowsiness,
diarrhea, abdominal pain, dizziness, infection and nervousness.

In October 1999, we initiated a Phase 3 open label, long-term safety study for
MT 100. Migraine patients in this trial receive a supply of MT 100 for use in
the treatment of any migraine attack that occurs. Adverse events are recorded
by each patient. Patients are evaluated every three months and may be treated
for up to 12 months. To date, over 1,000 patients have been recruited into this
trial, with approximately 800 having completed three months of treatment. The
trial will continue until 300 patients have been treated for at least six
months and 100 patients have been treated for at least 12 months.

We are currently conducting a Phase 3 multiple dosing study. In this trial,
patients with migraine randomly receive either placebo or a single tablet of MT
100. Those patients who continue to have moderate or severe headache pain at
two hours randomly receive a second tablet of either a placebo or MT 100. In
order to determine if multiple doses of MT 100 have beneficial effects, we will
compare the response rate of patients receiving two doses of MT 100 over four
hours with the response rate of patients receiving just one dose of MT 100
initially.

We are also conducting a Phase 3 pilot study of MT 100 as compared to Imitrex
and placebo. Patients with migraine randomly receive a single tablet of MT 100,
two tablets of MT 100, a 50mg tablet of Imitrex or placebo. The sustained
response endpoint as well as secondary endpoints will be observed for each
treatment option and compared against each other.

In addition to the ongoing or completed trials described above, we intend to
complete at least the following clinical trials prior to submitting an NDA for
MT 100:

    .  one Phase 3 clinical trial comparing MT 100 with each of its
       components; and

    .  two Phase 3 clinical trials comparing MT 100 to placebo.

                                       35
<PAGE>

Based on discussions with the FDA after completion of our initial Phase 3 trial
comparing MT 100 with its components, we believe that, in addition to showing a
statistically significant increase in patients achieving sustained response in
all of our trials, our planned Phase 3 placebo controlled trials must also
demonstrate that MT 100 is superior to placebo in three additional endpoints to
obtain FDA approval for the entire label that we intend to seek in migraine.
These additional endpoints are relief of nausea, sensitivity to light and
sensitivity to sound.

Even though the individual components of MT 100 have been available for many
years, we believe that we will also be required to complete toxicology studies
of MT 100, and we may be required to complete long-term carcinogenicity studies
of MT 100. The carcinogenicity studies, which are conducted with laboratory
animals, typically take approximately two and a half years to complete. Because
of the long history of usage of the individual components of MT 100, we
believe, that if these studies are required, they will be permitted to be
completed on a post-marketing basis. However, if the FDA requires long-term
carcinogenicity studies to be completed prior to approval of the NDA, it could
delay our planned commercialization of MT 100 in the U.S. for at least a year.

MT 300

MT 300 is being developed to provide long-lasting pain relief for patients
needing a convenient injectable therapy for severe migraine, with a reduced
side effect profile compared to existing injectable products. Currently,
patients often use an injectable form of triptans or other drugs such as
dihydroergotamine mesylate, or DHE, to alleviate the symptoms of the most
severe migraine attacks quickly and effectively. However, many patients are
unable to tolerate the injections, especially those sensitive to the vascular
side effects associated with injectable Imitrex. Nevertheless, according to
IMS, injectable migraine therapeutics represented approximately $188 million in
1999 U.S. sales.

MT 300 is a proprietary formulation of injectable DHE that we intend to package
in an easy-to-use, sterile, pre-filled syringe that can be administered alone
or with an auto-injector. Compared to the existing injectable DHE products, MT
300 appears to possess improved solubility and stability at room temperature.
We believe that these characteristics will allow us to supply patients in our
future clinical trials with MT 300 in pre-filled syringes, rather than the
difficult snap-ring glass ampoules that are used to supply injectable DHE.

Injectable DHE is currently approved for use in the treatment of migraine and
cluster headache episodes. Based upon recently published clinical trial
results, injectable DHE has been shown to provide comparable efficacy to
injectable Imitrex three hours after administration. Importantly, only 18% of
injectable DHE patients experienced headache recurrence within 24 hours as
compared to 45% of injectable Imitrex patients. In addition, injectable
Imitrex's acute vascular side effects were reported by 23% of the patients
receiving injectable Imitrex, but by only 2% of the patients receiving
injectable DHE.

 MT 300 Clinical Trials

In November 1998, we completed a placebo controlled, dose-response Phase 2
clinical trial of MT 300. In this trial, eligible patients with an acute
migraine attack were treated in the physician's office, monitored for two hours
after the dose, and then discharged to record their symptoms on a diary card
for the remainder of the 24-hour study period. Participants in the study were
divided into four dosing groups, with three receiving varying doses of MT 300
and one receiving placebo. A total of 291 patients received a single
subcutaneous dose of MT 300 or placebo in this study. In this clinical trial,
MT 300 at the highest dosing level demonstrated a statistically significant
improvement in the percentage of patients achieving four-hour sustained
response when compared to placebo. MT 300 was well tolerated and no serious
adverse events were reported. The most commonly reported side effect

                                       36
<PAGE>

was nausea, reported by 4% of patients in the high dose group. The four-hour
sustained response rate used in this trial differs from the sustained response
measure used thus far in our clinical trials of MT 100 and MT 400, in that the
four-hour rate measures pain reduction after four hours, without return to
moderate or severe pain or rescue over the next 20 hours.

We plan to initiate a 300 patient placebo controlled Phase 3 clinical trial of
a single, subcutaneous dose of MT 300 in patients with moderate to severe
migraine by the end of 2000. It is likely that we will be required to conduct
an additional Phase 3 trial prior to submitting an NDA for MT 300.

MT 500

MT 500 is being developed as an orally administered drug for the prophylactic
treatment of migraine pain. The prophylaxis market is currently composed of
drugs such as anticonvulsants, beta-blockers and anti-depressants, which were
developed primarily for uses outside of migraine. Many have side effects
including fatigue, sexual dysfunction, weight gain, insomnia and liver
toxicity. Studies of the migraine patient population indicate that
approximately 25% of migraine patients experience four or more migraine attacks
per month. We believe these patients may benefit from the prophylactic
treatment of their migraine attacks.

In September 1999, utilizing our license back option model, we obtained an
exclusive worldwide license for MT 500, a novel serotonin (5-HT\\2\\B) receptor
antagonist discovered by Roche. We believe that MT 500 is the first orally
administered, highly selective 5-HT\\2\\B receptor antagonist being developed
specifically for the prophylactic treatment of migraine in patients suffering
frequent and debilitating attacks. At the onset of a migraine attack, 5-
HT\\2\\B receptors are believed to be activated by a mobilization of serotonin,
provoking inflammation of the nerves in cerebral blood vessels and leading
ultimately to the pain and associated symptoms of migraine. By selectively
blocking the 5-HT\\2\\B receptor, MT 500 may prevent or reduce the occurrence
of migraine without producing the unwanted side effects associated with
currently used prophylactic migraine therapies.

 MT 500 Clinical Trials

MT 500 has been evaluated in five Phase 1 clinical trials and one Phase 2
clinical trial conducted by Roche. The Phase 2 trial was for an indication
unrelated to migraine. In all studies, MT 500 was generally well tolerated.
There were no serious adverse events reported, and side effects were generally
mild or moderate.

We intend to initiate a Phase 1 tolerance study of MT 500 in the third quarter
of 2000. In addition, at the conclusion of longer term toxicology studies
currently underway, we intend to initiate a placebo controlled Phase 2 proof-
of-concept study in migraine prophylaxis in the first half of 2001.

MT 400

We are developing MT 400 as a co-active migraine therapy, which combines the
activity of a commercially approved triptan drug with that of a commercially
approved long-acting, non-steroidal, anti-inflammatory drug. We believe that
the effective treatment of migraine requires targeted, specific and
complementary co-active therapy to achieve maximum therapeutic benefit with the
fewest side effects. We believe that MT 400 will prove to offer a faster onset
of action and a longer duration of migraine symptom relief than monotherapy
with either agent. In addition, since lower doses of the triptan components
could be used in certain MT 400 formulations relative to triptan monotherapy,
we believe that the potential risks of triptan-related side effects may also be
reduced with MT 400.

MT 400 represents a commercially attractive opportunity to create multiple
products based on different combinations of triptans and long acting, non-
steroidal, anti-inflammatory drugs. We believe these MT 400 products will be
attractive to pharmaceutical companies due to their potential to expand the
reach

                                       37
<PAGE>

of the existing triptan brands to patients with less severe migraine, offer
maximum oral therapy for severe attacks, provide an effective route for the
over-the-counter transfer of the triptan brand and potentially expand the
proprietary life of most triptan brands.

 MT 400 Clinical Trials

In 1998, we completed an open label pilot study for MT 400. In this study, MT
400 had a 74% higher sustained response rate and a substantially lower relapse
rate compared to triptan monotherapy. Based on these positive results, we plan
to initiate double-blind Phase 2 clinical trials of MT 400 during 2000. In
order to commercialize MT 400, we will need to license the rights to a triptan.

Product In-Licensing

In order to continue to expand our product pipeline, we intend to complement
our internal product innovations by in-licensing additional product candidates.
Our in-licensing strategy to obtain new product candidates will include using
our license back option model, which we believe provides us with improved
access to promising compounds. Specifically, the major elements of our license
back option model are:

  .  We in-license a product candidate at the late preclinical or Phase 1
     development stage.

  .  We grant the licensor an option to license back the product candidate at
     various stages of development.

  .  We assume all development and funding responsibility.

  .  If the licensor exercises its option to license back the product
     candidate, we receive certain milestone payments and a royalty on sales
     of the product candidate.

  .  If the licensor foregoes its option, we have the right to license the
     product candidate to another third party or commercialize the product
     ourselves, with sublicense royalties in both cases being paid to the
     original licensor.

  .  All financial terms are set when the original license agreement is
     signed.

We believe our license back option model offers advantages to both us and the
licensor and will be an effective tool in expanding our product portfolio
successfully. The advantages of this model for the licensor include:

  .  realization of value from product candidates whose development would
     otherwise be delayed or never undertaken;

  .  delayed commitment of resources and capital until the product
     candidate's technical risk and commercial potential are better defined;
     and

  .  utilization of our product development and regulatory expertise.

We believe the advantages of our license back option model for us include:

  .  improving our access to attractive product candidates;

  .  limiting our financial exposure to product candidate development
     expenses due to low upfront costs compared to traditional in-licensing
     structures; and

  .  in-licensing product candidates with substantial preclinical development
     risk removed.

We used our license back option model to acquire the migraine prophylactic
agent, MT 500, from Roche in September 1999. In exchange for an upfront
payment, Roche granted us a royalty-bearing,

                                       38
<PAGE>

exclusive, worldwide license to develop and commercialize MT 500. Under the
terms of the agreement, Roche can exercise its right to license back MT 500
following completion of either the Phase 2 or Phase 3 clinical trials in
exchange for set milestone payments. If Roche does not exercise either of its
options to license back MT 500, we have the right to sublicense to a third
party the commercialization rights for MT 500 or to commercialize the product
ourselves in exchange for fixed royalties payable to Roche. If we sublicense
MT 500, we are obligated to pay Roche a set percentage of any milestone
payments and royalties we receive from the third party sublicensees.

Sales and Marketing

We currently have no sales or distribution capabilities. We intend to
commercialize our products through other pharmaceutical companies in exchange
for upfront and milestone payments, proceeds from the manufacturing of drug
substance and royalties. In the future, we may retain the right to co-promote
our products.

Manufacturing

We currently have no manufacturing capability and we currently do not intend to
establish internal manufacturing capabilities. To date, we have entered into
arrangements with third party manufacturers for the supply of formulated and
packaged MT 100 clinical trial materials. Use of third party manufacturing
enables us to focus on our clinical development strengths, minimize fixed costs
and capital expenditures and gain access to advanced manufacturing process
capabilities and expertise.

We believe our current supply of compounds and product candidates, together
with our current suppliers' capacity, should be sufficient to complete both our
ongoing and planned clinical trials.

We intend to enter into agreements with third party manufacturers for the
commercial scale manufacturing of our products. We are negotiating a contract
with the manufacturer of our clinical trial materials to manufacture MT 100
commercially.

Competition

Not all migraine attacks are of the same severity. Consequently, a variety of
oral, injectable and intranasal therapies are used to treat different types of
migraine attacks. Attacks are often treated initially with simple over-the-
counter analgesics, particularly if the patient is unable to determine if the
attack is a migraine or some other type of headache. These analgesics include
Excedrin Migraine(R), which is approved for the pain associated with migraine.
If over-the-counter remedies are unsuccessful, patients often turn to more
potent prescription drugs, including triptans. According to IMS, in 1999, total
triptan sales in the U.S. were approximately $1.1 billion. Imitrex, marketed by
Glaxo Wellcome, is the dominant triptan product, with total U.S. sales of
approximately $855 million in 1999, according to IMS.

Narcotics such as codeine and drugs containing analgesic/narcotic combinations,
along with other non-narcotic pain medications, are also used for the treatment
of migraine. If approved, our migraine product candidates will most likely
compete with one or more of the existing migraine therapeutics, as well as any
therapies developed in the future.

The pharmaceutical and biopharmaceutical industries are intensely competitive
and are characterized by rapid technological progress. Certain pharmaceutical
and biopharmaceutical companies and academic and research organizations
currently engage in, or have engaged in, efforts related to the discovery and
development of new medicines for the treatment of migraine symptoms.
Significant levels of research in chemistry and biotechnology occur in
universities and other nonprofit research institutions. These entities have
become increasingly active in seeking patent protection and licensing revenues
for their research results. They also compete with us in recruiting skilled
scientific talent.

                                       39
<PAGE>

Our ability to compete successfully will be based on our ability to create and
maintain scientifically advanced technology, develop proprietary products,
attract and retain scientific personnel, obtain patent or other protection for
our products, obtain required regulatory approvals and manufacture and
successfully market our products either alone or through outside parties. Some
of our competitors have substantially greater financial, research and
development, manufacturing, marketing and human resources and greater
experience in product discovery, development, clinical trial management, FDA
regulatory review, manufacturing and marketing than we do.

Patents and Proprietary Information

We intend to actively seek, when appropriate, protection for our products and
proprietary technology by means of U.S. and foreign patents, trademarks and
contractual arrangements. In addition, we plan to rely upon trade secrets and
contractual agreements to protect certain of our proprietary technology and
products.

We own or have exclusive rights to four issued U.S. patents, two allowed U.S.
patent applications, three pending U.S. patent applications and one pending
U.S. provisional application. In addition, we presently have pending foreign
patent applications or issued foreign patents relating to MT 100, MT 400 and MT
500. Applications have been filed under the Patent Cooperation Treaty, or PCT,
and are in international phase which relate to MT 300 and MT 400. There can be
no assurance that our patent applications will issue as patents or, with
respect to our issued patents, that they will provide us with significant
protection. The following provides a general description of our patent
portfolio and is not intended to represent an assessment of claim limitations
or claim scope.

MT 100

We have one allowed U.S. application with claims to dosage forms that can be
used in administering metoclopramide and a long acting non-steroidal anti-
inflammatory drug to a patient with migraine headache. There are also claims to
a method of manufacturing a specific type of dosage form. We have one pending
U.S. patent application with claims directed to various pharmaceutical
compositions and treatment methods that can be used for migraine patients. In
addition, there are applications relating to MT 100 that are pending in
Australia, Canada, Europe and Japan.

MT 300

With respect to MT 300, we presently have one pending U.S. application and one
pending international application filed under the PCT. Both of these have
claims directed to liquid pharmaceutical compositions for treating migraine
which contain concentrated dihydroergotamine. There are also claims to treating
patients for migraine using these compositions and to therapeutic packages
which include the compositions.

MT 500

Through our license agreement with Roche, we have exclusive worldwide rights to
patents and patent applications relating to MT 500. In the U.S., we have
exclusive rights to three issued patents. These have claims directed to certain
chemical compounds and to various treatment methods involving the use of the
compounds. Related non-U.S. applications are pending or have issued in numerous
countries including Australia, Canada, Europe and Japan.

                                       40
<PAGE>

MT 400

We have one issued U.S. patent with claims directed to methods and compositions
relating to the use of the combination of a 5-HT receptor agonist and an
analgesic in treating patients with migraine. We also have an allowed U.S.
application with claims to methods, compositions and therapeutic packages
involving the use of certain non-steroidal anti-inflammatory drugs and 5-HT
receptor agonists. Outside of the U.S., we have applications relating to MT 400
pending in Australia, Canada, Europe and Japan. In addition there is one
pending U.S. application and one pending international application with claims
to dosage forms and methods of treatment involving a 5-HT receptor agonist and
a particular subset of NSAIDs.

Other Intellectual Property

Much of the know-how of importance to us is dependent upon the knowledge,
experience and skills of key scientific and technical personnel. To protect our
rights to proprietary know-how and technology, we require employees,
consultants and advisors to enter into confidentiality agreements which
prohibit the disclosure of confidential information to anyone outside of the
Company. There can be no assurance that these agreements will effectively
prevent disclosure of our confidential information. In the absence of effective
patent or other protection of intellectual property, our business may be
adversely affected by competitors who develop substantially equivalent or
superior technology or know-how.

We also have one international application filed under the PCT which is
entitled "Prophylaxis and Treatment of Migraine Headaches with Thromboxane
Synthetase Inhibitors and/or Receptor Antagonists."

The patent and other intellectual property positions of pharmaceutical
companies are highly uncertain and involve complex legal and factual questions.
We cannot assure you that:

 . our patent rights will provide us with proprietary protection or
   competitive advantages against our competitors;

 . our patent applications will not be challenged, invalidated or
   circumvented;

 . others will not independently develop technologies similar to ours or
   duplicate our technologies; or

 . the patents issued to or licensed by us will not be infringed or
   challenged.

Government Regulation

The FDA and comparable regulatory agencies in state and local jurisdictions and
in foreign countries impose substantial requirements on the clinical
development, manufacture and marketing of pharmaceutical product candidates.
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 and
promotion of our product candidates. All of our product candidates will require
regulatory approval before commercialization. In particular, therapeutic
product candidates for human use are subject to rigorous preclinical and
clinical testing and other requirements of the Federal Food, Drug, and Cosmetic
Act (FFDCA), implemented by the FDA, as well as similar statutory and
regulatory requirements of foreign countries. Obtaining these marketing
approvals and subsequently complying with ongoing statutory and regulatory
requirements is costly and time-consuming. Any failure by us or our
collaborators, licensors or licensees to obtain, or any delay in obtaining,
regulatory approvals or in complying with other requirements could adversely
affect the commercialization of product candidates then being developed by us
and our ability to receive product or royalty revenues.

                                       41
<PAGE>

The steps required before a new drug product candidate may be distributed
commercially in the U.S. generally include:

    .  conducting appropriate preclinical laboratory evaluations of the
       product candidate's chemistry, formulation and stability and
       preclinical studies to assess the potential safety and efficacy of
       the product candidate;

    .  submitting the results of these evaluations and tests to the FDA,
       along with manufacturing information and analytical data, in an
       investigational new drug application, or IND;

    .  initiating clinical trials under the IND after the resolution of any
       safety or regulatory concerns of the FDA;

    .  obtaining approval of Institutional Review Boards, or IRBs, to
       introduce the drug into humans in clinical studies;

    .  conducting adequate and well-controlled human clinical trials that
       establish the safety and efficacy of the product candidate for the
       intended use, typically in the following three sequential, or
       slightly overlapping stages;

              Phase 1: The product is initially introduced into human subjects
              or patients and tested for safety, dose tolerance, absorption,
              metabolism, distribution and excretion;

              Phase 2: The product candidate is studied in patients to
              identify possible adverse effects and safety risks, to determine
              dosage tolerance and the optimal dosage, and to collect some
              efficacy data;

              Phase 3: The product candidate is studied in an expanded patient
              population at multiple clinical study sites, to confirm efficacy
              and safety at the optimized dose, by measuring a primary
              endpoint established at the outset of the study;

    .  submitting the results of preclinical studies, and clinical trials as
       well as chemistry, manufacturing and control information on the
       product candidate to the FDA in an NDA; and

    .  obtaining FDA approval of the NDA prior to any commercial sale or
       shipment of the product candidate.

This process can take a number of years and require substantial financial
resources. The results of preclinical studies and initial clinical trials are
not necessarily predictive of the results from large-scale clinical trials, and
clinical trials may be subject to additional costs, delays or modifications due
to a number of factors, including the difficulty in obtaining enough patients,
clinical investigators, product candidate supply, or financial support. The FDA
may also require testing and surveillance programs to monitor the effect of
approved product candidates that have been commercialized, and the agency has
the power to prevent or limit further marketing of a product candidate based on
the results of these post-marketing programs. Upon approval, a product
candidate may be marketed only in those dosage forms and for those indications
approved in the NDA.

In addition to obtaining FDA approval for each indication to be treated with
each product candidate, each domestic product candidate manufacturing
establishment must register with the FDA, list its product with the FDA, comply
with cGMP regulations and permit and pass manufacturing plant inspections by
the FDA. Moreover, the submission of applications for approval may require
additional time to complete manufacturing stability studies. Foreign
establishments manufacturing product for distribution in the U.S. also must
list their product candidates with the FDA and comply with cGMP regulations.
They are also subject to periodic inspection by the FDA or by local authorities
under agreement with the FDA.

                                       42
<PAGE>

Any product candidates manufactured or distributed by us pursuant to FDA
approvals are subject to extensive continuing regulation by the FDA, including
record-keeping requirements and reporting of adverse experiences with the
product candidate. In addition to continued compliance with standard regulatory
requirements, the FDA may also require post-marketing testing and surveillance
to monitor the safety and efficacy of the marketed product. Adverse experiences
with the product candidate must be reported to the FDA. Product approvals may
be withdrawn if compliance with regulatory requirements is not maintained or if
problems concerning safety or efficacy of the product are discovered following
approval.

The FFDCA also mandates that products be manufactured consistent with cGMP
regulations. In complying with the FDA's regulations on cGMP regulations,
manufacturers must continue to spend time, money and effort in production,
record-keeping quality control, and auditing to ensure that the marketed
product meets applicable specifications and other requirements. The FDA
periodically inspects manufacturing facilities to ensure compliance with cGMP
regulations. Failure to comply subjects the manufacturer to possible FDA
action, such as warning letters, suspension of manufacturing, seizure of the
product, voluntary recall of a product or injunctive action, as well as
possible civil penalties. We currently rely on, and intend to continue to rely
on, third parties to manufacture our compounds and product candidates. These
third parties will be required to comply with cGMP regulations.

Even after the FDA approval has been obtained, further studies, including post-
marketing studies, may be required. Results of post-marketing studies may limit
or expand the further marketing of the products. If we propose any
modifications to a product, including changes in indication, manufacturing
process, manufacturing facility or labeling, a supplement to our NDA may be
required to be submitted to the FDA.

Products manufactured in the U.S. for distribution abroad will be subject to
FDA regulations regarding export, as well as to the requirements of the country
to which they are shipped. These latter requirements are likely to cover the
conduct of clinical trials, the submission of marketing applications, and all
aspects of manufacturing and marketing. Such requirements can vary
significantly from country to country.

We are also subject to various federal, state and local laws, rules,
regulations and policies relating to safe working conditions, laboratory and
manufacturing practices, the experimental use of animals and the use of and
disposal of hazardous or potentially hazardous substances used in connection
with our research work. Although we believe that our safety procedures for
handling and disposing of such materials comply with current federal, state and
local laws, rules, regulations and policies, the risk of accidental injury or
contamination from these materials cannot be entirely eliminated.

The extent of government regulation which might result from future legislation
or administrative action cannot be accurately predicted. In this regard,
although the Food and Drug Administration Modernization Act of 1997 modified
and created requirements and standards under the FFDCA Act with the intent of
facilitating product development and marketing, the FDA is still in the process
of developing regulations implementing the Food and Drug Administration
Modernization Act of 1997. Consequently, the actual effect of these
developments on our own business is uncertain and unpredictable.

Stock Option and Other Compensation Plans

We adopted our stock option plan in November 1996. We authorized a total of
1,190,000 shares of our common stock for issuance under our stock option plan.
At March 31, 2000, options to purchase 1,029,583 shares of common stock at a
weighted average exercise price of $1.23 per share were outstanding and options
convertible into 117,045 shares of common stock remain available for future
grant. Options to purchase an aggregate of 43,372 shares of common stock have
been exercised under our stock option plan.

Our stock option plan provides for grants of stock options to our employees and
directors and to our consultants and advisors who perform valuable services for
us. Our stock option plan is intended to further our growth and success by
enabling our employees, directors, consultants and advisors to acquire shares
of our common stock, thereby increasing their personal interest in our growth
and success.

Our stock option plan may be administered by our Board of Directors or a
committee appointed by our Board of Directors. In accordance with the
provisions of our stock option plan, the Board of Directors has the authority
to determine the persons to whom stock options will be granted, the number of
shares to be covered by each stock option, and the exercise price per share.
The Board of Directors also has the authority to prescribe, amend and rescind
rules and regulations relating to our stock option plan, to determine the
conditions that must be satisfied in order for a stock option to vest and
become exercisable, to accelerate the vesting or exercise date of any stock
option, and to interpret our stock option plan or any agreement entered into
with respect to a stock option under the plan.

The exercise price of options granted under the plan is determined by our Board
of Directors; however, the exercise price of incentive stock options granted
under the plan must be equal to at least the fair market value of common stock
on the date of grant (or 110% of the fair market value if the grant is made to
a 10% or more stockholder). Other restrictions on the terms applicable to
incentive stock options are imposed under the plan to ensure compliance with
the requirements for incentive stock options under Section 422 of the Internal
Revenue Code.

The exercise price for shares of our common stock subject to an option under
our stock plan may, at the discretion of the Board of Directors or the
committee, be paid in cash, by check or with cash equivalents.

In the event that:

  .  we merge with or consolidate into another corporation, which results in
     our stockholders owning less than 50% of the voting power of the voting
     securities of the surviving corporation, or

  .  we sell, lease or otherwise dispose of all or substantially all of our
     assets,

then any unvested options become fully vested as of a date prior to the merger,
consolidation, sale, lease or other disposition of assets. Any option that
becomes vested and exercisable solely because of this provision is conditioned
upon the consummation of the transaction that gave rise to the accelerated
vesting. Our Board of Directors may, in its discretion, terminate any
unexercised options that become vested and exercisable solely because of this
provision.

Our Board of Directors may suspend, amend or terminate our stock option plan,
subject to any required approval by our stockholders.

401(k) Profit Sharing Plan

We maintain a 401(k) Profit Sharing Plan which is intended to be a tax-
qualified defined contribution plan under Section 401(k) of the Code. In
general, all of our employees are eligible to participate. The 401(k) Plan
includes a salary deferral arrangement pursuant to which participants may
contribute,

                                       49
<PAGE>

subject to certain Code limitations, a maximum of 15% of their salary on a pre-
tax basis, up to a maximum of $10,000. We do not currently make any
contributions to the Plan. Distributions from the 401(k) Plan may be made in
the form of a lump-sum cash payment or in installment payments.

Other Employment Arrangements

Our principal employees, including executive officers, are required to sign an
agreement restricting solicitation of customers and employees following
employment with us and providing for ownership and assignment of intellectual
property rights to us.

Under an executive employment agreement dated April 1, 1999, we agreed to
employ John R. Plachetka as our Chief Executive Officer for three years at an
annual base salary of $240,000, which is subject to performance and merit based
increases. The agreement automatically renews for successive one year terms
thereafter, unless either party terminates the agreement.

On January 1, 2000, we hired Andrew L. Finn as our Executive Vice President,
Product Development. In connection with his employment, we granted him options
to purchase 100,000 shares of common stock at an exercise price of $2.00 per
share. These options vest in equal installments over a three-year period.

On March 20, 2000, we hired Matthew E. Czajkowski as our Senior Vice President
and Chief Financial Officer. In connection with his employment, we granted him
options to purchase 110,000 shares of common stock at an exercise price of
$2.72 per share. These options vest in equal installments over a three-year
period.

Limitation of Liability and Indemnification of Officers and Directors

Our certificate of incorporation limits the personal liability of directors for
breach of fiduciary duty to the maximum extent permitted by the Delaware
General Corporation Law. Our certificate of incorporation provides that no
director will have personal liability to us or to our stockholders for monetary
damages for breach of fiduciary duty or other duty as a director. However,
these provisions do not eliminate or limit the liability of any of our
directors:

    .  for any breach of their duty of loyalty to us or our stockholders;

    .  for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

    .  for voting or assenting to unlawful payments of dividends or other
       distributions; or

    .  for any transaction from which the director derived an improper
       personal benefit.

Any amendment to or repeal of these provisions will not eliminate or reduce the
effect of these provisions in respect of any act or failure to act, or any
cause of action, suit or claim that would accrue or arise prior to any
amendment or repeal or adoption of an inconsistent provision. If the Delaware
General Corporation Law is subsequently amended to provide for further
limitations on the personal liability of directors of corporations, then the
personal liability of our directors will be further limited to the greatest
extent permitted by the Delaware General Corporation Law.

Our certificate of incorporation provides that we will indemnify our directors
and executive officers and may indemnify our other corporate agents to the
fullest extent permitted by law. We believe that indemnification under our
certificate of incorporation covers at least negligence and gross negligence on
the part of indemnified parties.

20,000 shares of common stock at an exercise price of $0.25 per share to each
of Jacques F. Rejeange and Bruce A. Tomason, in consideration for their
services as directors. On December 31, 1999, we granted options to purchase an

                             PRINCIPAL STOCKHOLDERS

The following table sets forth certain information with respect to the
beneficial ownership of our common stock as of March 31, 2000, and as adjusted
to reflect the sale of         shares of common stock in this offering, by:

    .  each person, or group of affiliated persons, who is known by us to
       beneficially own more than 5% of our common stock;

    .  each of our directors;

    .  each of our named executive officers; and

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

Except as otherwise noted, the persons or entities in this table have sole
voting and investing power with respect to all the shares of common stock
beneficially owned by them, subject to community property laws, where
applicable.

The "Number of Shares Beneficially Owned" column is based on an assumed
13,345,401 shares of common stock outstanding before the offering, and
shares of common stock outstanding after the offering. For purposes of the
table below, we deem shares of common stock subject to options that are
currently exercisable or exercisable within 60 days of March 31, 2000, to be
outstanding and to be beneficially owned by the person holding the options for
the purpose of computing the percentage ownership of the person but we do not
treat them as outstanding for the purpose of computing the percentage ownership
of any other person.

for future issuance pursuant to our stock option plan. Options to purchase
1,029,583 shares of common stock at a weighted average exercise price of $1.23

stock remain available for future grant. Options to purchase an aggregate of
43,372 shares of common stock have been exercised under our stock option plan
as of March 31, 2000.

Anti-Takeover Provisions

Under Delaware law, all stockholder actions must be effected at a duly called
annual or special meeting. Our bylaws provide that, except as otherwise
required by law, special meetings of the stockholders can only be called by our
Chairman of the Board, President or any two members of the Board of Directors.
In addition, our bylaws establish an advance notice procedure for stockholder
proposals to be brought before an annual meeting of stockholders, including
proposed nominations of persons for election to the board. Stockholders at an
annual meeting may only consider proposals or nominations specified in the
notice of meeting or brought before the meeting by or at the direction of the
board of directors or by a stockholder of record on the record date for the
meeting, who is entitled to vote at the meeting and who has delivered timely
written notice in proper form to our Secretary of the stockholder's intention
to bring such business before the meeting. The holders of a majority of our
outstanding shares will constitute a quorum for the transaction of business.
Each stockholder has one vote per share of stock. Except as explained below or
provided by Delaware law, approval of a majority of those stockholders who are
present is required to take any action.

Our certificate of incorporation and our bylaws provide that a director may be
removed from office only with cause by the affirmative vote of shareholders
holding 75% of the outstanding shares entitled to vote at an election of
Directors. Our bylaws may only be amended by our Board of Directors or by an
affirmative vote of shareholders holding 75% of our outstanding shares of
voting stock.

These provisions of our certificate of incorporation and bylaws are intended to
discourage types of transactions that may involve an actual or threatened
change of control of POZEN. Such provisions

                                       55
<PAGE>

are designed to reduce the vulnerability of POZEN to an unsolicited acquisition
proposal and, accordingly, could discourage potential acquisition proposals and
could delay or prevent a change in control of POZEN. Such provisions are also
intended to discourage tactics that may be used in proxy fights but could,
however, have the effect of discouraging others from making tender offers for
our shares and, consequently, may also inhibit fluctuations in the market price
of our shares that could result from actual or rumored takeover attempts. These
provisions may also have the effect of preventing changes in the management of
POZEN.

We are subject to Section 203 of the Delaware General Corporation Law, or the
anti-takeover law, which regulates corporate acquisitions. The anti-takeover
law prevents certain Delaware corporations, including those whose securities
are listed for trading on the Nasdaq National Market, from engaging under
certain circumstances in a "business combination" with any "interested
stockholder" for three years following the date that such stockholder became an
interested stockholder. For purposes of the anti-takeover law, a "business
combination" includes, among other things, a merger or consolidation involving
POZEN, and the "interested stockholder" and the sale of more than 10% of
POZEN's assets. In general, the anti-takeover law defines an "interested
stockholder" as any entity or person beneficially owning 15% or more the
outstanding voting stock of POZEN and any entity or person affiliated with or
controlling or controlled by such entity or person. In addition, the
restrictions contained in Section 203 are not applicable to any of our existing
stockholders. A Delaware corporation may "opt out" of the anti-takeover law
with an express provision in its original certificate of incorporation or an
express provision in its certificate of incorporation or bylaws resulting from
amendments approved by the holders of at least a majority of the corporation's
outstanding voting shares. We have not "opted out" of the provisions of the
anti-takeover law.

Registration Rights

Upon the completion of this offering, holders of 8,968,677 shares of our common
stock and 23,217 warrants will be entitled to certain rights with respect to
the registration of these shares under the Securities Act.

If we register any of our common stock, either for our own account or for the
account of other security holders, the holders of all of these shares are
entitled to notice of the registration and to include their shares of common
stock in the registration. All of these rights to register securities in
connection with this offering have been waived as required by the respective
agreements granting these rights.

Beginning 180 days after the completion of this offering, subject to specified
limitations, holders of 5,183,677 shares of common stock, representing shares
issued in conversion of our series D and E convertible preferred stock, and
23,217 shares issuable upon exercise of our warrants to purchase series E
preferred stock, may require that we register all or part of these securities
for sale under the Securities Act. Until we are entitled to register our shares
on Form S-3, a short form registration statement, these holders may only make
two such demands. Once we are entitled to use Form S-3, which may be as early
as       , 2001, holders of 2,613,144 of these shares may make such demands for
registrations on Form S-3 on an unlimited number of occasions and holders of
2,593,750 of these shares may make such demands for registrations on Form S-3
on up to two occasions.

Other than in a demand registration, a holder's right to include shares in a
registration is subject to the ability of the underwriters to limit the number
of shares included in the offering. All fees, costs and expenses of any demand
registrations and up to three registrations on Form S-3 all of these
registrations will be paid by us, and all selling expenses will be paid by the
holders of the securities being registered.

                        SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no market for our common stock, and we
cannot assure you that a liquid trading market for our common stock will
develop or be sustained after this offering. Future sales of substantial
amounts of common stock, including shares issued upon exercise of outstanding
options and warrants, in the public market after this offering or the
anticipation of those sales could adversely affect market prices prevailing
from time to time and could impair our ability to raise capital through sales
of our equity securities.

After the closing of this offering, we will have outstanding         shares of
common stock, which assumes the underwriters do not exercise their over-
allotment option and holders do not exercise any outstanding options or
warrants. Of these shares, the shares sold in this offering will be freely
tradable without restriction under the Securities Act unless purchased by our
"affiliates", as that term is defined in Rule 144 under the Securities Act.
Substantially all the remaining 13,345,401 restricted shares held by existing
stockholders are subject to various lock-up agreements providing that, with
limited exceptions, the stockholder will not offer, sell, contract to sell,
grant an option to purchase, effect a short sale or otherwise dispose of or
engage in any hedging or other transaction that is designed or reasonably
expected to lead to a disposition of any shares of common stock or any option
to purchase common stock or any securities exchangeable for or convertible into
common stock for a period of 180 days after the date of this prospectus. Though
these shares may be eligible for earlier sale under the provisions of the
Securities Act, none of these shares will be saleable until 180 days after the
date of this prospectus as a result of these lock-up agreements.

In general, under Rule 144 as currently in effect, a person, or persons whose
shares are aggregated, who has beneficially owned restricted shares for at
least one year is entitled to sell within any three-month period up to that
number of shares that does not exceed the greater of: (1) 1% of the number of
shares of common stock then outstanding, which will be approximately
shares immediately after this offering, or (2) the average weekly trading
volume of the common stock during the four calendar weeks preceding the filing
of a Form 144 with respect to the sale. Sales under Rule 144 are also subject
to certain "manner of sale" provisions and notice requirements and to the
requirement that we have made current public information about POZEN available.
Under Rule 144(k), a person who is not deemed to have been an affiliate of the
issuer 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,
including the holding period of any prior owner except an affiliate, is
entitled to sell those shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

Rule 701 permits resales of qualified shares held by some affiliates in
reliance upon Rule 144 but without compliance with some restrictions, including
the holding period requirement, of Rule 144. Any of our employees, officers,
directors or consultants who purchased his or her shares pursuant to a written
compensatory plan or contract prior to the completion of this offering may be
entitled to rely on the resale provisions of Rule 701. Rule 701 further
provides that non-affiliates may sell shares in reliance on Rule 144 without
having to comply with the holding period, public information, volume limitation
or notice provisions of Rule 144. All holders of Rule 701 shares of common
stock are required to wait until 90 days after the date of this prospectus
before selling shares. However, substantially all shares issued pursuant to
Rule 701 are subject to lock-up agreements and will only become eligible for
sale at the expiration of the 180 day lock-up.

Upon the completion of this offering, the holders of 8,968,677 shares of our
common stock and 23,217 warrants will be entitled to certain registration
rights under the Securities Act. See "Description of Capital Stock--
Registration Rights." After registration pursuant to these rights, these shares
will become freely tradable without restriction under the Securities Act.

                                       57

As of March 31, 2000, we had outstanding options to purchase 1,029,583 shares
of common stock. In addition, as of March 31, 2000, we had outstanding warrants
to purchase an aggregate of 347,327 shares of series A convertible preferred
stock, series B convertible preferred stock, series C convertible preferred
stock, series D convertible preferred stock and series E convertible preferred
stock, respectively, all of which will convert immediately prior to the
consummation of this offering into warrants to purchase an aggregate of 347,327
shares of common stock. Substantially all of such shares are subject to the
lock-up agreements described above. As of March 31, 2000, an additional 117,045
shares of common stock were available for future grants under our stock option
plan.

Following this offering, we intend to file a registration statement on Form S-8
under the Securities Act to register all shares of common stock subject to
outstanding stock options and options issuable pursuant to our stock option
plan. Subject to the lock-up agreements, shares covered by this registration
statement will be eligible for sale in the public markets, other than shares
owned by our affiliates, which may be sold in the public market if they qualify
for an exemption from registration under Rule 144 or 701.

                                  UNDERWRITING

Subject to certain terms and conditions contained in an underwriting agreement,
the underwriters named below, for whom U.S. Bancorp Piper Jaffray Inc. is
acting as representative, have severally agreed to purchase the number of
shares of common stock from us set forth opposite their names below:

     Total.....................................................
                                                                    =======
</TABLE>

The underwriting agreement provides that the obligations of the several
underwriters to purchase shares of common stock are subject to the approval of
certain legal matters by counsel and to certain other conditions. If any of the
shares of common stock are purchased by the underwriters pursuant to the
underwriting agreement, all such shares of common stock (other than the shares
of common stock covered by the over-allotment option described below) must be
so purchased.

We have been advised by U.S. Bancorp Piper Jaffray Inc. that the underwriters
propose to offer the shares of common stock to the public initially at the
price to the public set forth on the cover page of this prospectus and to
certain dealers (who may include the underwriters) at such price less a
concession not to exceed $   per share. The underwriters may allow, and such
dealers may reallow, discounts not in excess of $   per share to any other
underwriter and certain other dealers.

We have granted to the underwriters an option to purchase up to      additional
shares of common stock at the initial public offering price less the
underwriting discount solely to cover over-allotments. Such option may be
exercised in whole or in part from time to time during the 30-day period after
the date of this prospectus. To the extent that the underwriters exercise such
option, each of the underwriters will be committed, subject to certain
conditions, to purchase a number of option shares proportionate to such
underwriter's initial commitment as indicated in the preceeding table. If the
underwriters exercise their option in full, the total price to the public would
be $    , the total underwriting discount would be $     and total proceeds to
us would be $   .

We, together with certain of our stockholders and our executive officers and
directors, have agreed not to directly or indirectly offer, pledge, sell,
contract to sell, sell any option or contract to purchase or grant any option,
right or warrant to purchase or otherwise transfer or dispose of any shares of
common stock or any securities convertible into or exercisable or exchangeable
for common stock, or enter into any swap or other arrangement that transfers
all or a portion of the economic consequences associated with the ownership of
such common stock, or to cause a registration statement covering any shares of
common stock to be filed, for a period of 180 days after the date of this
prospectus without the prior written consent of the underwriters, subject to
limited exceptions. See "Shares Eligible for Future Sale."

Prior to this offering, there has been no established trading market for the
common stock. The initial price to the public for the common stock offered by
us will be determined by negotiation among the underwriter representatives and
us. The factors to be considered in determining the initial price to the public
will include the history of and the prospects for the industry in which we
compete, the ability of our management, our past and present operations, our
prospects for future earnings, the general condition of the securities markets
at the time of this offering and the recent market prices of securities of
generally comparable companies. We will apply to list our common stock on the
Nasdaq National Market.

The underwriters do not intend to make sales to accounts over which they
exercise discretionary authority in excess of 5% of the number of shares of
common stock offered hereby.

                                       59
<PAGE>

To facilitate the offering, the underwriters may engage in transactions that
stabilize, maintain, or otherwise affect the price of the common stock during
and after the offering. Specifically, the underwriters may over-allot or
otherwise create a short position in the common stock for their own account by
selling more shares of common stock than have been sold to them by us. The
underwriters may elect to cover any such short position by purchasing shares of
common stock in the open market or by exercising the over-allotment option
granted to the underwriters. In addition, the underwriters may stabilize or
maintain the price of the common stock by bidding for or purchasing shares of
common stock in the open market and may impose penalty bids. If penalty bids
are imposed, selling concessions allowed to syndicate members or other broker-
dealers participating in the offering are reclaimed if shares of common stock
previously distributed in the offering are repurchased, whether in connection
with stabilization transactions or otherwise. The effect of these transactions
may be to stabilize or maintain the market price of the common stock at a level
above that which might otherwise prevail in the open market. The impositions of
a penalty bid may also effect the price of the common stock to the extent that
it discourages resale of the common stock. The magnitude or effect of any
stabilization or other transactions is uncertain. These transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

U.S. Bancorp Piper Jaffray Inc. beneficially owns warrants to purchase 23,217
shares of our series E convertible preferred stock, which will convert
immediately prior to consummation of this offering into warrants to purchase
23,217 shares of our common stock, at an exercise price of $6.95 per share.
These warrants were acquired by U.S. Bancorp Piper Jaffray in connection with a
private placement of our series E preferred stock which was completed in March
2000. U.S. Bancorp Piper Jaffray received reasonable and customary compensation
for their placement services in connection with the private placement,
including the warrants and a right of first refusal to act as lead manager in
connection with this offering. The Company also reimbursed U.S. Bancorp Piper
Jaffray for reasonable out-of-pocket expenses incurred in connection with the
private placement and indemnified it against certain liabilities.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
POZEN Inc.

We have audited the accompanying balance sheets of POZEN Inc. (a development
stage company) as of December 31, 1998 and 1999, and the related statements of
operations, stockholders' equity (deficit) and cash flows for each of the three
years ended December 31, 1999, and for the period from September 25, 1996
(inception) through December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of POZEN Inc. (a development
stage company) at December 31, 1998 and 1999 and the results of its operations
and its cash flows for each of the three years ended December 31, 1999, and for
the period from September 25, 1996 (inception) through December 31, 1999 in
conformity with accounting principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES

Development Stage Company--The Company is a pharmaceutical company committed to
building a portfolio of products with significant commercial potential in
select therapeutic areas. The Company's initial area of focus is migraine,
where it has built a portfolio of four product candidates through a combination
of innovation and in-licensing. The Company's lead product candidate is MT 100,
which is being developed as an oral first-line therapy for the treatment of
migraine. The Company has completed its initial Phase 3 clinical trial of MT
100 and intends to initiate three additional Phase 3 clinical trials of MT 100
by the end of 2000. In addition to the MT 100 trials, the Company expects to
begin two additional Phase 3 or Phase 2 clinical trials for two other migraine
product candidates by the end of 2000.

In order to continue to expand its product pipeline, the Company intends to
complement its internal product innovations by in-licensing additional product
candidates. The Company intends to commercialize its product candidates through
other pharmaceutical companies in exchange for upfront and milestone payments,
proceeds from the manufacturing of drug substance and royalties. In the future,
the Company may retain the right to co-promote its products.

Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts in the financial statements
and accompanying notes. Actual results could differ from the estimates and
assumptions used.

Cash and Cash Equivalents--The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.
Cash is invested in interest-bearing investment-grade securities.

Equipment--Equipment consists primarily of furniture and fixtures and is
recorded at cost. Depreciation is computed using the straight-line method over
the estimated useful lives of the assets ranging from five to seven years.

Research and Development Costs--Research and development costs are charged to
operations as incurred.

Income Taxes--The Company accounts for income taxes using the liability method.
Deferred income taxes are provided for temporary differences between financial
reporting and tax bases of assets and liabilities.

Unaudited Financial Information--The accompanying financial statements and
related notes to the financial statements as of March 31, 2000 and for the
three months ended March 31, 1999 and 2000 are unaudited, but in the opinion of
management, include all adjustments consisting of normal recurring adjustments
necessary for a fair presentation of results for the interim periods.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been omitted for the March 31 periods, although the Company believes that
the disclosures included are adequate to make the information presented not
misleading. Results for the three months ended March 31, 2000 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2000.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

Non-Cash Preferred Stock Charge--In accordance with EITF 98-5, the Company has
recorded a non-cash preferred stock charge on the Series E which represents the
excess of the fair market value of the underlying common stock and warrants
issued to the Series E holders over the sale price of the securities.


Net Loss Per Share--Basic and diluted net loss per common share are presented
in conformity with the Statement of Financial Accounting Standards No. 128,
"Earnings per Share" ("SFAS 128"), for all periods presented. Following the
guidance given by the Securities and Exchange Commission Staff Accounting
Bulletin No. 98, common stock and convertible preferred stock that has been
issued or granted for nominal consideration prior to the anticipated effective
date of the initial public offering must be included in the calculation of
basic and diluted net loss per common shares as if these shares had been
outstanding for all periods presented. To date, the Company has not issued or
granted shares for nominal consideration.

In accordance with SFAS 128, basic and diluted net loss per common share has
been computed using the weighted-average number of shares of common stock
outstanding during the period. Pro forma basic and diluted net loss per common
share, as presented in the statements of operations, has been computed for the
year ended December 31, 1999 and the three months ended March 31, 2000 as
described above, and also gives effect to the conversion of the convertible
preferred stock that will automatically convert to common stock immediately
prior to the completion of the Company's initial public offering (using the if-
converted method) from the original date of issuance.

The Company has excluded all convertible preferred stock, outstanding stock
options, and warrants from the calculation of net loss per common share because
such securities are antidilutive for all periods presented. Had the Company
been in a net income position, these securities would have been included in the
calculation. These potentially dilutive securities consist of the following:

Stock Based Compensation--The Company accounts for stock options issued to
employees in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25"). Under APB 25, no
compensation expense is recognized for stock or stock options issued with an
exercise price equivalent to the fair value of the Company's Common Stock.

In October 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock Based Compensation." For companies that continue to account for stock
based compensation arrangements under APB 25, SFAS 123 requires

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

disclosure of the pro forma effect on net income (loss) as if the fair value
based method prescribed by SFAS 123 had been applied. The Company has adopted
the pro forma disclosure requirements of SFAS 123.

Comprehensive Income--As of January 1, 1998, the Company adopted SFAS 130,
"Reporting Comprehensive Income." SFAS 130 established new rules for the
reporting and display of comprehensive income or loss and its components;
however, the adoption of this statement had no impact on the Company's
operating results or stockholders' equity (deficit).

Segment Reporting--As of January 1, 1998, the Company adopted SFAS 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS 131
establishes standards for the way companies report information about operating
segments in annual financial statements. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. The Company has determined that it does not have any separately
reportable operating segments as of December 31, 1999.

Recently Issued Accounting Standards--In June 1998, the FASB issued SFAS 133,
"Accounting for Derivative Investments and Hedging Activities," SFAS 133
establishes a new model for accounting for derivatives and hedging activities
and supersedes several existing standards. SFAS 133, as amended by SFAS 137, is
effective for all fiscal quarters of fiscal years beginning after June 15,
2000. The Company does not expect that the adoption of SFAS 133 will have a
material impact on its financial statements.

2. STOCKHOLDERS' EQUITY (DEFICIT)

In December 1996, the Company completed a private placement of 2,105,931 of its
Series A Convertible Preferred Stock ("Series A") and received cash of
$5,475,420 and notes receivable of $1,000,000, net of offering costs. The notes
receivable were collected during 1997. The terms of the Series A provide for
conversion into common shares by dividing $3.15 by the conversion price at any
time. The conversion price is initially $3.15 subject to increases or decreases
based on certain defined events. Holders of Series A shall have the number of
votes based on the number of common shares that would be obtained from
conversion. Series A shall be paid dividends in any year in which dividends on
common shares have been declared and paid. In conjunction with the issuance of
the Series A, in January 1997, the Company issued warrants to purchase 78,776
shares of Series A at a purchase price of $0.001 per share to certain key
advisors. The value of the warrants is reflected in additional paid-in capital.

In December 1997 and March 1998, the Company completed a private placement of
1,135,000 of its Series B Convertible Preferred Stock ("Series B") and received
cash of $4,336,000, net of offering costs. The terms of the Series B provide
for similar conversion, voting and dividend rights as those defined in the
Series A. At December 31, 1997, the Company was obligated to issue warrants to
purchase 36,450 shares of Series B at a purchase price of $0.001 per share to
certain key advisors. The value of the warrants is reflected in additional
paid-in capital.

In March 1998, the Company issued an additional 4,377 shares of its Series B
for $17,512 interest accrued on the funds received prior to the December 1997
Series B private placement.

On March 4, 1998, the Company amended its Certificate of Incorporation to
increase the number of authorized shares of common stock, par value $.001, from

In March 1998, the Company completed a private placement of 563,044 of its
Series C Convertible Preferred Stock ("Series C") and received cash of
$2,205,813, net of offering costs. The terms of the Series C provide for
similar conversion, voting and dividend rights as those defined in the Series A
and Series B. In conjunction with the issuance of the Series C, the Company
issued warrants to purchase 8,884 shares of Series C at a purchase price of
$0.001 per share to certain key advisors. The value of the warrants is
reflected in additional paid-in capital.

In July 1999, the Company amended its Certificate of Incorporation to increase
the number of authorized shares of common stock, par value $0.001 per share,
from 20,000,000 shares to 30,000,000 shares and the number of authorized shares
of preferred stock, par value $0.001 per share, from 10,000,000 shares to
20,000,000 shares.

In July and September 1999, the Company completed a private placement of
2,593,750 of its Series D Convertible Preferred Stock ("Series D") and received
cash of $12,000,000. The terms of the Series D provide for similar conversion,
voting and dividend rights as those defined in the Series A, Series B and
Series C. In conjunction with the issuance of the Series D, the Company issued
warrants to purchase 200,000 shares of Series D at a purchase price of $3.15
per share to BB Medtech AG related to $3 million in bridge financing funded by
MEDGROWTH S.A. ("MEDGROWTH") in March 1999 through a Convertible Promissory
Note. The value of the warrants is reflected in additional paid-in capital. The
Convertible Promissory Note was converted into Series D at completion of the
private placement noted above. MEDGROWTH received Series D valued at $450,000
as an origination fee upon conversion of the Convertible Promissory Note.

In the event of any liquidation, dissolution or winding up of the Company, the
holders of the preferred stock are entitled to receive an amount equal to their
initial purchase price per share, plus any accrued but unpaid dividends. After
payments have been made to the holders of preferred stock, any remaining assets
of the Company will be distributed to holders of the common stock.

At March 31, 2000, shares of common stock reserved for future issuance are as
follows:

      Shares available for grant under stock option plan.....     117,045

3. REDEEMABLE PREFERRED STOCK

On March 24, 2000, the Company completed a private placement of 2,589,927 of
its Series E Convertible Preferred Stock ("Series E") and received cash of
$16,875,115, net of offering costs. The terms of the Series E provide for
similar conversion, voting and dividend rights and liquidation preference as
those defined in the Series A, Series B, Series C and Series D. In addition,
the terms of conversion provide for an increase in conversion price if the
Company is unable to complete a qualified public offering or to effect a merger
or acquisition of the Company that would entitle the holders of the Series E to
receive $10.43 or more per share. At the date of issuance, the Company believes

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

share price of $6.95 represented the fair value of the preferred stock and was
in excess of the deemed fair value of its common stock. Subsequent to the
commencement of the Company's initial public offering process, the Company re-
evaluated the deemed fair market value of its common stock as of March 2000 and
determined it to be $15.00 per share. Accordingly, the incremental fair value
is deemed to be the equivalent of a preferred stock dividend. The Company
recorded the non-cash preferred stock charge at the date of issuance by
offsetting charges and credits to additional paid-in capital of $16,875,115,
without any effect on total stockholders' equity.

The terms of the Series E also provide for a mandatory redemption commencing on
March 23, 2005, March 23, 2006 and March 23, 2007, respectively, and continuing
for a period of 60 days after each such date or at a earlier date as a majority
or more of the capital stock is sold in a single transaction or a series of
related transactions when the holders of 75% of the issued and outstanding
shares of the Series E elect to cause a redemption. The redemption price is the
greater of the appraised value as defined or the original purchase price of the
Series E plus any accrued but unpaid dividends. Default in the payment of any
required redemption of Series E entitles the holders of Series E to elect a
majority of the Board of Directors and receive special voting rights.

In conjunction with the issuance of the Series E, the Company issued warrants
to purchase 23,217 shares of Series E at a purchase price of $6.95 per share to
certain key advisors. The value of the warrants is reflected in additional
paid-in capital.

5. INCOME TAXES

At December 31, 1998 and 1999 and March 31, 2000, the Company had federal and
state net operating loss carryforwards of approximately $11 million, $22
million and $24 million, respectively, for income tax purposes. At December 31,
1998 and 1999 and March 31, 2000, the Company had research and development
credit carryforwards of approximately $490,000, $685,000 and $807,000,
respectively. The federal net operating loss carryforwards and research and
development credit carryforwards begin to expire in 2012. State net operating
loss carryforwards begin to expire in 2001. For financial reporting purposes, a
valuation allowance has been recognized to offset the deferred tax assets
related to the carryforwards. When, and if recognized, the tax benefit for
those items will be reflected in current operations of the period in which the
benefit is recorded as a reduction of income tax expense. The utilization of
the loss carryforwards to reduce future income taxes will depend on the
Company's ability to generate sufficient taxable income prior to the expiration
of the net operating loss carryforwards. In addition, the maximum annual use of
net operating loss carryforwards is limited in certain situations where changes
occur in stock ownership.

6. STOCK OPTION PLAN

On November 20, 1996, the Company established a Stock Option Plan and
authorized the issuance of up to 1,190,000 options to attract and retain
quality employees and to allow such employees to participate in the growth of
the Company. Awards may be made to participants in the form of incentive and
nonqualified stock options. Eligible participants under the Plan include
executive or key employees of the Company. The vesting period ranges from
immediate vesting at issuance to three years or immediately upon a significant
change in ownership as defined by the plan document. The exercise price for
incentive stock options may not be less than 100% of the fair market value of
the common stock on the date of grant (110% with respect to incentive stock
options granted to optionees who are 10% or more stockholders of the Company).

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


Exercise prices for options outstanding as of December 31, 1997, 1998 and 1999
were $0.25-$2.00. The weighted-average fair value of options granted for all
periods presented is $3.23 per share. The weighted-average remaining
contractual life of the options is nine years. At December 31, 1997, 1998 and
1999, 51,761, 129,450 and 260,734 options were exercisable, respectively.

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," ("Statement 123")
requires use of option valuation models that were not developed for use in
valuing employee stock options.

During the year ended December 31, 1999, in connection with the grant of
certain share options to employees, the Company recorded deferred compensation
of $2.1 million, representing the difference between the exercise price and the
deemed fair value of the Company's common stock for financial reporting
purposes on the date such stock options were granted. Deferred compensation is
included as a reduction of stockholders' equity and is being amortized to
expense according to the vesting method. During the year ended December 31,
1999, the Company recorded amortization of deferred compensation of
approximately $168,000.

During the period March 31, 2000, in connection with the grant of certain share
options to employees, the Company recorded deferred compensation of $2.7
million, representing the difference between the exercise price and the deemed
fair value of the Company's common stock for financial reporting purposes on
the date such stock options were granted. During the period ended March 31,
2000, the Company recorded amortization of deferred compensation of
approximately $373,000.

Pro forma information regarding net income is required by Statement 123, and
has been determined as if the Company had accounted for its employee stock
options under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using the minimum value option
pricing model with the following weighted-average assumptions: risk-free
interest rates of 6.4%; dividend yields of 0%; and a weighted-average expected
life of the option of 10 years.

The minimum value option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions. Because the Company's employee stock options
have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options. For purposes of pro forma disclosures, the estimated fair value
of the options is amortized to expense over the options' vesting period. For
purposes of pro forma disclosures, the estimated fair value of the options is
amortized to expense over the options' vesting periods. The Company's pro forma
net loss information is as follows:

8. RETIREMENT SAVINGS PLAN

In July 1997, the Company began a defined contribution 401(k) pension plan (the
"Plan") covering substantially all employees who are at least 21 years of age.
Based upon management's discretion, the Company may elect to make contributions
to the Plan. For the years ended December 31, 1997, 1998 and 1999, and for the
period September 25, 1996 (inception) through December 31, 1999, the Company
did not make any contributions to the Plan.

9. SUBSEQUENT EVENTS (unaudited)

In April 2000, the Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission to register shares of its
common stock in connection with a proposed Initial Public Offering (the
"Offering"). If the Offering is consummated, the preferred stock outstanding as
of the closing date will be converted into shares of the Company's common
stock. Pro forma net loss per common share is computed as if the outstanding
preferred stock had been converted into common stock on the date of issuance.

Item 14. Indemnification of Directors and Officers

The Registrant's Certificate of Incorporation permits indemnification to the
fullest extent permitted by Delaware law and require the Registrant to
indemnify any person who was or is an authorized representative of the
Registrant, and who was or is a party or is threatened to be made a party to
any corporate proceeding, by reason of the fact that such person was or is an
authorized representative of the Registrant, against expenses, judgments,
penalties, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such third party proceeding if such
person acted in good faith and in a manner such person reasonably believed to
be in, or not opposed to, the best interests of the Registrant and, with
respect to any criminal third party proceeding (including any action or
investigation which could or does lead to a criminal third party proceedings
had no reasonable cause to believe such conduct was unlawful. The Registrant
shall also indemnify any person who was or is an authorized representative of
the Registrant and who was or is a party or is threatened to be made a party to
any corporate proceeding by reason of the fact that that such person was or is
an authorized representative of the Registrant, against expenses actually and
reasonably incurred by such person in connection with the defense or settlement
of such corporate action if such person acted in good faith and in a manner
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Registrant unless and only to the extent that the Delaware Court
of Chancery or the court in which such corporate proceeding was pending shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such authorized representative is
fairly and reasonably entitled to indemnity for such expenses which the Court
of Chancery or such other court shall deem proper. Such indemnification is
mandatory as to expenses actually and reasonably incurred to the extent that an
authorized representative of the Registrant had been successful on the merits
or otherwise in defense of any third party or corporate proceeding or in
defense of any claim, issue or matter therein. The determination of whether an
individual is entitled to indemnification may be made by a majority of
disinterested directors, independent legal counsel in a written legal opinion
or the stockholders. Delaware law also permits indemnification in connection
with a proceeding brought by or in the right of the Registrant to procure a
judgment in its favor. Insofar as indemnification for liabilities arising under
the Act may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in that Act and is
therefore unenforceable.

                                      II-1

The Underwriting Agreement provides that the underwriter is obligated, under
certain circumstances, to indemnify directors, officers, and controlling
persons of the Registrant against certain liabilities, including liabilities
under the Act. Reference is made to Section     of the form of Underwriting
Agreement which will be filed by amendment as Exhibit 1.1 hereto.

Item 17. Undertakings

(a) 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.

(b) Insofar as indemnification for liabilities arising under the Securities Act
    may be permitted to directors, officers and controlling persons of the
    Registrant pursuant to the foregoing provisions, 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 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 whether such indemnification by it is against
    public policy as expressed in the Securities Act and will be governed by
    the final adjudication of such issue.

(c) The Registrant hereby undertakes that:

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

  (ii) For purposes of determining any liability under the Securities Act,
  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.

               ADDITIONAL RENT- OPERATING EXPENSE PASS THROUGHS

Tenant agrees to pay to Landlord, as additional rent, each year after the first
complete twelve (12) month period of occupancy ("Base Year"), in a lump sum,
Tenant's proportionate share of any increase in direct expenses incurred on
account of the operation or maintenance of the building in which the Demised
Premises are situated, above such direct expense paid or incurred by Landlord
for the Base Year.

Commencing with the first month of the second lease year, and each lease year
thereafter, there shall be added to Tenant's monthly payments an amount to cover
Tenant's pro rata share of operational pass throughs as estimated by Landlord to
have increased during the previous year, which figure (so estimated by Landlord)
shall be paid by Tenant until such time as actual figures are available (after
the end of the second and successive years), when the monthly increment for pass
throughs shall be adjusted to reflect the prior year's experience. Landlord
shall send to Tenant, in writing, a statement of the amount of any additional
rent plus any applicable sales or use taxes payable by Tenant hereunder on or
before one hundred and twenty (120) days after the end of the lease year with
respect to which the rent adjustment is due, and within thirty (30) days
thereafter Tenant shall pay any additional rent shown to be due Landlord, or
Landlord shall adjust Tenant's payments if any credit is shown to be due Tenant.
Tenant shall remain liable after the end of the term for any amount of
operational pass throughs for the final year if such exceeded Tenant's payments
for the pass throughs and Tenant shall be entitled to a refund if such payments
exceeded Tenant's payments for the pass throughs and Tenant shall be entitled to
a refund if such payments exceeded the pass throughs.

Tenant's proportionate share shall be calculated by dividing the 5,938 rentable
square feet of the Demised Premises by the 94.461 rentable square feet of the
building, which equals 6.29%.

The term "direct expense" as used herein shall include direct costs of
operation, repair and maintenance as determined by standard accounting practices
and shall include by way of illustration, but is not limited to ad valorem real
and personal property taxes, hazard and liability insurance premiums. utilities,

<PAGE>

include depreciation on the building in which the Demised Premises are situated
or equipment therein, interest, executive salaries, real estate brokers'
commissions marketing costs or principal and interest payments, or other
expenses that do not relate to the operation of the building. The annual
statement of said direct expense, accounted for and reported in accordance with
generally accepted accounting principles, shall be available to Tenant upon
written request.

For purposes of verifying Landlord's computation and proration of Direct
Expenses, including the computation of Controllable Expenses. and to verify
Landlord's compliance with this Lease with respect to which items of expense
appropriately constitute Direct Expenses. Tenant or its authorized agents. at
its sole cost and expense, except as set forth below, during normal business
hours. may inspect, audit and copy the books and records of Landlord and its
agents. If any such audit reveals an error by Landlord with respect to Direct
Expenses, Landlord shall promptly reimburse Tenant for the amount erroneously
overcharged to Tenant. In the event such error exceeds 6% of the total average
amount then Landlord shall reimburse Tenant for reasonable costs of the audit.

insurance is required by this Lease Agreement and even if the insured peril
shall be brought about by the default, negligence or other action of the
Landlord, Landlord's agents, employees or any of them; provided, this release
shall be in effect only with respect to an insured loss and only so long as
Tenant's policy applicable to such loss contains a clause to the effect that

by Landlord and that the Lease Agreement is in full force and effect except as
to modifications, agreements or amendments thereto, copies of each of which
including the Lease Agreement shall be attached. Failure by Tenant to comply
with any such request within such seven (7) day period shall be deemed a
conclusive admission by Tenant that this Lease Agreement remains in full force
and effect, that Tenant has no defense thereto and that Landlord is not in
breach thereunder.

                                      24.
                       CURING DEFAULTS AND LATE CHARGES

compliance shall have been provided to Tenant) then, in each such case, upon the
expiration of the time provided in this Lease Agreement (except in the case of
emergency situations in which event the time frame may be shortened as
appropriate) Landlord may perform and comply therewith for the account and at
the expense of Tenant: and Tenant upon receipt of an itemized invoice of the

more of the following shall constitute an "Event of Default" hereunder:

          such failure continues for a period of seven (7) business days after
          written notice thereof is delivered to Tenant by Landlord.
          Notwithstanding the foregoing, Landlord shall only be obligated to
          give such written notice 3 times in any 12 month period and then upon
          the 4th failure of Tenant to make timely payment, such failure shall
          constitute an Event of Default.

     (ii) Tenant breaches any other agreement or obligation herein set forth and
          shall fail to cure such breach within thirty (30) days after written
          notice is sent by Landlord; provided that if such cure by its nature
          takes more than 30 days and Tenant is diligently pursuing such cure,
          then Tenant shall not be in breach of this Lease so long as Tenant
          promptly commences the cure thereof and diligently prosecutes such

     (b)    Upon the occurrence of any Event of Default, Landlord shall be
entitled, by written notice to the Tenant, to accelerate all rents and other
sums due for the remainder of the Lease, and shall be further entitled to either
(i) to terminate the term hereof or (ii) to terminate Tenant's right to
possession or occupancy only, without terminating the term of this Lease
Agreement. Unless the term is specifically terminated by notice in writing, it
shall be assumed that the Landlord has elected to terminate possession only,
without terminating the term. Any termination of the term or of possession only
shall not affect Tenant's obligations to pay accelerated rent, unaccelerated
rent or any other sums due for the remainder of the Lease.

     (c)    The remedies of terminating the term, of terminating possession or
otherwise as provided in this Lease Agreement shall be cumulative and in
addition to and not in limitation of any rights and remedies otherwise available
to the Landlord and the exercise of any rights and remedies on default shall not
preclude the exercise of any other rights and remedies available to the Landlord
at law or in equity or otherwise.

            LANDLORD'S RIGHTS ON TERMINATION OF TERM OR POSSESSION

     (a) Upon any termination of the initial or extended term hereof, whether by
lapse of time or otherwise, or upon any termination of Tenant's right to
possession or occupancy only, without terminating the term hereof, Tenant shall
surrender possession and vacate the Demised Premises and shall deliver
possession thereof to the Landlord; and Tenant hereby grants to Landlord full
and free license to enter into and upon the Demised Premises in such event to
repossess the Demised Premises as of Landlord's former estate and to expel or
remove Tenant and any others who may be occupying the Demised Premises and to
remove therefrom any and all property, without being guilty of or liable for
trespass, eviction or forcible entry or detainer and without relinquishing
Landlord's right to rent or any other right given to Landlord hereunder or by
operation of the laws of the State of North Carolina.

     (b) If Landlord elects to terminate Tenant's right to possession only as
above provided, without terminating the term hereof. Landlord at its option may
enter into the Demised Premises, remove Tenant's property and other evidences of
tenancy and take and hold possession thereof without such entry and possession
terminating the term hereof and without releasing Tenant from its obligation to
pay rents or accelerated rent and other monetary obligations herein reserved for
the full term hereof. Upon and after entry into possession without terminating
such obligations, Landlord shall use reasonable efforts to relet the Demised
Premises, or any part for the account of Tenant to any person, firm or
corporation other than Tenant for such reasonable rent, for such time, and upon
such reasonable terms as Landlord in its sole discretion shall determine. If any
rent is to be collected by Landlord upon any such reletting for Tenant's Account
is not sufficient to pay the full amount of accelerated rent or any other rent
herein reserved (including additional rents and other charges) and any other
monetary obligations hereunder, and not heretofore paid by Tenant, together with
the reasonable costs of retaking possession and any repairs, alterations, or
redecoration necessary for such reletting, Tenant shall pay to Landlord the
amount of the entire deficiency upon demand, and if the rent to be collected
from such reletting is more than enough to pay the full amount of accelerated
rent or the rents reserved hereunder and all of the aforementioned costs,
Landlord shall be entitled to retain such excess. Notwithstanding any
termination of the right to possession without termination of the term, the
Landlord expressly reserves the right, at any time after the termination of
possession, to terminate the term of this Lease Agreement by notice of such
termination to Tenant.

     (c) The foregoing rights and remedies of Landlord are in addition to any
other rights and remedies Landlord may have at law or in equity.

periods after a default under any of the terms, covenants, and conditions herein
contained to be performed, kept and observed by Tenant shall not be deemed a

Agreement for any other failure or for the continued failure by Tenant to so
perform, keep or observe its covenants, terms and conditions to be kept,
performed and observed by it. No waiver by Landlord of any of the terms or
conditions of this Lease Agreement shall be construed as a waiver by Landlord of
any subsequent default on the part of Tenant.

                  STRATEGIC PHARMACEUTICAL DEVELOPMENT, INC.
                               STOCK OPTION PLAN


1.   Purpose.  The Strategic Pharmaceutical Development, Inc. Stock Option Plan
     -------
     (the "Plan") is established to create an additional incentive for key
     employees, directors and consultants or advisors of Strategic
     Pharmaceutical Development, Inc. and any successor corporations thereto
     (collectively referred to as the "Company"), and any present or future
     parent and/or subsidiary corporations of such corporation (all of whom
     along with the Company being individually referred to as a "Participating
     Company" and collectively referred to as the "Participating Company
     Group"), to promote the financial success and progress of the Participation
     Company Group.  For purposes of the Plan, a parent corporation and a
     subsidiary corporation shall be as defined in Sections 424(e) and 424(f) of
     the Internal Revenue Code of 1986, as amended (the "Code").

2.   Administration.  The Plan shall be administered by the Board of Directors
     --------------
     of the Company (the "Board") and/or by a duly appointed committee of the
     Board having such powers as shall be specified by the Board.  Any
     subsequent references herein to the Board shall also mean the committee if
     such committee has been appointed and, unless the powers of the committee
     have been specifically limited, the committee shall have all of the powers
     of the Board granted herein, other than power to terminate or amend the
     Plan as provided in section 12 hereof, subject to the terms of the Plan and
     any applicable limitations imposed by law.  All questions of interpretation
     of the Plan or of any option granted under the Plan (an "Option") shall be
     determined by the Board, and such determinations shall be final and binding
     upon all persons having an interest in the Plan and/or any Option.  Options
     may be either incentive stock options as defined in Section 422 of the Code
     ("Incentive Stock Options") or nonqualified stock options.  Any officer of
     a Participating Company shall have the authority to act on behalf of the
     Company with respect to any matter, right, obligation, or election which is
     the responsibility of or which is allocated to the Company herein, provided
     the officer has apparent authority with respect to such matter, right,
     obligation, or election.

3.   Eligibility.  The Options may be granted only to employees (including
     -----------
     officers) and directors of the Participating Company Group or to
     individuals who are rendering services as consultants, advisors or other
     independent contractors to the Participating Company Group.  The Board, in
     its sole discretion, shall determine which persons shall be granted Options
     (an "Optionee").  A director of the Company shall be eligible to be granted
     only a nonqualified stock option unless the director is also an employee of
     the Company.  An individual who is rendering services as a consultant,
     advisor, or other independent contractor shall be eligible to be granted
     only a nonqualified stock option.  An Optionee may, if otherwise eligible,
     be granted additional Options.

4.   Shares Subject to Option.  Options shall be options for the purchase of the
     ------------------------
     authorized but unissued common stock of the Company (the "Stock"), subject
     to adjustment as provided in paragraph 10 below.  The maximum number of
     shares of Stock which may be issued
<PAGE>

     under the Plan shall be One Million, One Hundred Ninety Thousand
     (1,190,000) shares. In the event that any outstanding Option for any reason
     expires or is terminated or cancelled and/or shares of Stock subject to
     repurchase are repurchased by the Company, the shares allocable to the
     unexercised portion of such Option, or such repurchased shares, may again
     be subject to an Option grant. It is intended that the Plan shall
     constitute a written compensatory benefit plan within the meaning of Rule
     701 promulgated under the Securities Act of 1933, as amended ("Rule 701"),
     and that the Plan shall otherwise be administered in compliance with the
     requirements of Rule 701. To ensure such compliance, the Board shall
     maintain a record of shares subject to outstanding Options under the Plan
     and the exercise price of such Options, plus a record of all shares of
     Common Stock issued upon the exercise of such Options and the exercise
     price of such Options.

5.   Time for Granting Options.  All Options shall be granted, if at all, within
     -------------------------
     ten (10) years from the earlier of the date the Plan is adopted by the
     Board or the date the Plan is duly approved by the shareholders of the
     Company.

6.   Terms, Conditions and Form of Options.  Subject to the provisions of the
     -------------------------------------
     Plan, the Board shall determine for each Option (which need not be
     identical) the number of shares of Stock for which the Option is granted,
     whether the Option is to be treated as an Incentive Stock Option or as a
     nonqualified stock option and all other terms and conditions of the Option
     not inconsistent with the Plan.  Options granted pursuant to the Plan shall
     comply with and be subject to the following terms and conditions:

     (a)  Option Price.  The option price for each Option shall be established
          ------------
          in the sole discretion of the Board; provided, however, that (i) the
          option price per share for an Incentive Stock Option shall be not less
          than the fair market value of a share of Stock on the date of the
          granting of the Incentive Stock Option and (ii) the option price per
          share of an Incentive Stock Option granted to an Optionee who at the
          time the Incentive Stock Option is granted owns stock possessing more
          than ten percent (10%) of the total combined voting power of all
          classes of stock of a Participating Company within the meaning of
          section 422(b)(6) of the Code (a "Ten Percent Owner Optionee") shall
          be not less than one hundred ten percent (110%) of the fair market
          value of a share of Stock on the date the Option is granted.  For this
          purpose, "fair market value" means the value assigned to the stock for
          a given day by the Board, as determined pursuant to a reasonable
          method established by the Board that is consistent with the
          requirements of sections 422 and 424 of the Code and the regulations
          thereunder (which method may be changed from time to time).
          Notwithstanding the foregoing, an Option (whether an Incentive Stock
          Option or a nonqualified stock option) may be granted by the Board in
          its discretion with an exercise price lower than the minimum exercise
          price set forth above if such Option is granted pursuant to an
          assumption or substitution for another option in a manner qualifying
          with the

                                       2
<PAGE>

          provisions of section 424(a) of the Code. Nothing hereinabove shall
          require that any such assumption or modification will result in the
          Option having the same characteristics, attributes or tax treatment as
          the Option for which it is substituted.

     (b)  Exercise Period of Options.  The Board shall have the power to set the
          --------------------------
          time or times within which each Option shall be exercisable or the
          event or events upon the occurrence of which all or a portion of each
          Option shall be exercisable and the term of each Option; provided,
          however, that (i) no Incentive Stock Option shall be exercisable after
          the expiration of ten (10) years after the date such Incentive Stock
          Option is granted, (ii) no Incentive Stock Option granted to a Ten
          Percent Owner Optionee shall be exercisable after the expiration of
          five (5) years after the date such Incentive Stock Option is granted
          and (iii) no Incentive Stock Option shall be exercisable after the
          date the Optionee's employment with the Participating Company Group is
          terminated for cause (as determined in the sole discretion of the
          Board); and provided, further, an Option shall terminate and cease to
          be exercisable no later than three (3) months after the date on which
          the Optionee terminates employment with the Participating Company
          Group, unless the Optionee's employment with the Participating Company
          Group shall have terminated as a result of the Optionee's death or
          disability (within the meaning of Section 22(e)(3) of the Code), in
          which event the Option shall terminate and cease to be exercisable no
          later than twelve (12) months from the date on which the Optionee's
          employment terminated.  For this purpose, an Optionee's employment
          shall be deemed to have terminated on account of death if the Optionee
          dies within three (3) months following the Optionee's termination of
          employment.

     (c)  Payment of Option Price.  Payment of the option price for the number
          -----------------------
          of shares of Stock being purchased pursuant to any Option shall be
          made in cash, by check or cash equivalent.

     (d)  $100,000 Limitation.  The aggregate fair market value, determined as
          -------------------
          of the date on which an Incentive Stock Option is granted, of the
          shares of Stock with respect to which incentive stock options
          (determined without regard to this subsection) are first exercisable
          during any calendar year (under this Plan or under any other plan of
          the Participating Company Group) by any Optionee shall not exceed
          $100,000.  If such limitation would be exceeded with respect to an
          Optionee for a calendar year, the Incentive Stock Option shall be
          deemed a nonqualified stock option to the extent of such excess.

7.   Standard Form of Stock Option Agreement.  All Options shall be evidenced by
     ---------------------------------------
     a written award agreement in the form of the nonqualified stock option
     agreement attached hereto as Exhibit A or the incentive stock option award
                                  ---------
     agreement attached hereto as Exhibit B, as applicable, both of which are
                                  ---------
     incorporated herein by reference (the "Standard Option Agreements").

                                       3
<PAGE>

8.   Transfer of  Control. Upon a merger, consolidation, corporate
     --------------------
     reorganization, or any transaction in which all or substantially all of the
     assets of the Company are sold, leased, transferred or otherwise disposed
     of (other than a mere reincorporation transaction or one in which the
     holders of capital stock of the Company immediately prior to such merger or
     consolidations continue to hold at least a majority of the voting power of
     the surviving corporation) (a "Transfer of Control"), then any
     unexercisable portion of an outstanding Option shall become immediately
     exercisable as of a date prior to the Transfer of Control, which date shall
     be determined by the Board.  The exercise of any Option that was
     permissible solely by reason of this paragraph 8 shall be conditioned upon
     the consummation of the Transfer of Control.  The Board may further elect,
     in its sole discretion to provide that any Options which became exercisable
     solely by reason of this paragraph 8 and which are not exercised as of the
     date of the Transfer of Control shall terminate effective as of the date of
     the Transfer of Control.

9.   Authority to Vary Terms.  The Board shall have the authority from time to
     -----------------------
     time to vary the terms of the Standard Option Agreements either in
     connection with the grant of an individual Option or in connection with the
     authorization of a new standard form or forms; provided, however, that the
     terms and conditions of such revised or amended standard form or forms of
     stock option agreement shall be in accordance with the terms of the Plan.
     Such authority shall include, but not by way of limitation, the authority
     to grant Options which are not immediately exercisable.

10.  Effect of Change in Stock Subject to Plan.  The Board shall make
     -----------------------------------------
     appropriate adjustments in the number and class of shares of Stock subject

     outstanding Options in the event of a stock dividend, stock split, reverse
     stock split, combination, reclassification or like change in the capital
     structure of the Company.

11.  Options Non-Transferable.  During the lifetime of the Optionee, the Option
     ------------------------
     shall be exercisable only by the Optionee.  No Option shall be assignable
     or transferable by the Optionee, except by will or by the laws of descent
     and distribution.

12.  Termination or Amendment of Plan.  The Board may terminate or amend the
     --------------------------------
     Plan at any time; provided however, that without the approval of the
     Company's shareholders, there shall be (a) no increase in the total number
     of shares of Stock covered by the Plan (except by operation of the
     provisions of paragraph 10 above), (b) no change in the class of persons
     eligible to receive Incentive Stock Options, and (c) no extension of the

     Company or the date the Plan is approved by the shareholders of the
     Company.  In any event, no amendment may adversely affect any then
     outstanding Option or any unexercised portion thereof, without the consent
     of the Optionee, unless such amendment is required to enable an Option

                                       4
<PAGE>

     designated as an Incentive Stock Option to qualify as an Incentive Stock
     Option.

13.  Miscellaneous
     -------------

          any Optionee any right to continue in the employ of the Participating
          Company Group, or to serve as a director thereof, or interfere in any
          way with the right of a Participating Company to terminate his or her
          employment at any time.  Unless specifically provided otherwise, no
          grant of an Option shall be deemed salary or compensation for the
          purpose of computing benefits under any employee benefit plan or other
          arrangement of a Participating Company for the benefit of its
          employees unless the Participating Company shall determine otherwise.
          No Optionee shall have any claim to an Option until it is actually
          granted under the Plan.  To the extent that any person acquires a
          right to receive payments from the Company under the Plan, such right
          shall, except as otherwise provided by the Board, be no greater than
          the right of an unsecured general creditor of the Company.  All
          payments to be made hereunder shall be paid from the general funds of
          the Company, and no special or separate fund shall be established and
          no segregation of assets shall be made to assure payment of such
          amounts, except as otherwise provided by the Committee.

     (b)  The Plan and the grant of Options hereunder shall be subject to all
          applicable federal and state laws, rules, and regulations and to such
          approvals by any United States government or regulatory agency as may
          be required.

     (c)  The terms of the Plan shall be binding upon the Company, and its
          successors and assigns.

     (d)  This Plan and all actions taken hereunder shall be governed by the
          laws of the State of North Carolina.

     (e)  With respect to any payments not yet made to a Optionee by the
          Company,  nothing contained herein shall give any such Optionee any
          rights that are greater than  those of a general creditor of the
          Company.

     (f)  If any provision of this Plan or a Standard Option Agreement is or
          becomes or is deemed invalid, illegal or unenforceable in any
          jurisdiction, or would disqualify the Plan or any Standard Option
          Agreement under any law deemed applicable by the Board, such provision
          shall be construed or deemed amended to conform to applicable laws or
          if it cannot be construed or deemed amended without, in the
          determination of the Board, materially altering the intent of the Plan
          or the Standard Option  Agreement, it shall be stricken and the
          remainder of the Plan or the Standard Option Agreement shall remain in
          full force and effect.

NOW THEREFORE, in consideration of the foregoing and the provisions and mutual
promises herein contained and other good and valuable consideration, the parties

5.   TERMINATION.  This Agreement shall or may be terminated, as the case may

<PAGE>

     (a)  Severance Period. In the event of termination of employment for
          reasons other than for cause or voluntary termination (as defined
          below) or in the event that the office from which the Employee
          performs his principal duties is moved more that 50 miles from the
          outer boundaries of Wake, Orange and Durham County, North Carolina, or
          in the event that the Employee's duties and responsibilities as Chief
          Executive Officer are substantially reduced, the Employee shall
          receive severance pay in an amount equal to one years' base salary

          prior to the date of the Employee's termination of employment for one
          year following the date of termination or until the Employee obtains
          comparable coverage from another employer. At any time during the
          severance period, the Company may elect to pay a lump sum amount to
          the Employee which represents the reasonable value of such benefits
          reduced to their present value in lieu of continuing payment of
          benefits.
     (b)  Voluntary Termination. This Agreement shall be considered voluntarily
          terminated by the parties if either party provides written notice of
          his/its intent to not renew this Agreement, provided that such party

          prior to the last day of the initial term or any renewal term.
     (c)  Involuntary Termination. The Company may terminate this Agreement upon
          written notice to the Employee (or his representative) in any of the
          following events:
          (I)   In the event of death of the Employee,
          (II)  In the event that the Employee becomes permanently disabled; or
          (III) "For cause" which shall include breach of the terms of this
                Agreement; breach of the Nondisclosure, Invention, Non-
                Competition Agreement (described in Section 6 below); material
                failure by the Employee to comply with the policies or
                directives of the Board of Directors; any illegal or dishonest
                action that is materially detrimental to the Company; or failure
                to faithfully carry out the duties of his position, provided
                that the Company shall provide at least thirty (30) days written
                notice of such failure to perform during which time the employee
                may remedy the situation.

     For purposes of this Agreement, the Employee shall be considered
     permanently disabled when a qualified medical doctor mutually acceptable to
     the Company and the Employee or his personal representative shall have
     certified in writing that:  (i) he is unable because of medically
     determinable physical or mental disability to perform substantially all of
     his duties for more than one hundred eighty (180) calendar days measured
     from the last full day of work; or (ii) by reason of mental or physical
     disability, it is unlikely that he will be able, within

                                                                               3
<PAGE>

     one hundred eighty (180) calendar days, to resume substantially all
     business duties and responsibilities in which he was previously engaged and
     otherwise discharge his duties under this Agreement.

     In the event that the Employee is terminated pursuant to this Section 5 or
     upon termination of the Agreement, the Employee agrees to tender his
     resignation as a member of the Board of Directors of the Company as of the
     date of such termination.

6.   NON-DISCLOSURE, INVENTION, AND NON COMPETITION. The Employee shall execute
     the standard non-disclosure, invention, and non competition agreement,
     which is hereby made a part of this Agreement as Exhibit B attached hereto.

7.   NOTICES. Any notice required to be given shall be in writing personally
     delivered by certified mail or registered mail or by facsimile (receipt
     confirmed) to the address last shown in the Company's records.

8.   SEVERABILITY. The provisions of this Agreement shall be deemed severable,
     and the invalidity or unenforceability of any provision (or part thereof)
     of this Agreement shall in no way affect the validity or enforceability of
     any other provision (or remaining part thereof).

9.   GOVERNING LAW. This Agreement shall be governed by and construed according
     to the laws of the State of North Carolina, without reference to the choice
     of law provisions of such laws.

     parties relating to the subject matter hereof, and the parties hereto have
     made no agreements, representations, or warranties relating to the subject

     obligations under this Agreement without the written consent of the Board
     of Directors.

12.  The Employee understands and agrees that the Company will suffer
     irreparable harm in the event that the Employee breaches any of his
     obligations under this Agreement and that monetary damages will be
     inadequate to compensate the Company for such breach. Accordingly, the
     Employee agrees that, in the event of a breach or threatened breach by the
     Employee of any of the provisions of this Agreement, the Company, in
     addition to and not in limitation of any other rights, remedies, or damages
     available to the Company at law or in equity, shall be

                                                                               4

which are contemporaneously maintained.

     2.   Definition of Proprietary Information.  For purposes of this
          -------------------------------------
Agreement, the term "Proprietary Information" shall mean all of the following
materials and information (whether or not reduced to writing and whether or not
patentable or protectable by copyright) which Employee receives, receives access
to, conceives of or develops, in whole or in part, as a direct or indirect
result of his employment with Employer, in the course of his employment with
Employer (in any capacity, whether executive, managerial, planning, technical,
sales, research, development, manufacturing, engineering or otherwise) or
through the use of any of Employer's facilities or resources:

               (i)   Manufactured products, assembled or unassembled, and any
related goods or systems and any and all future products, software or systems
developed or derived therefrom;

                                                                               8
<PAGE>

               (ii)  With respect to the items described in Section 2(i) above,
all hardware and software relating to design or manufacture; all source and
object codes to such hardware and software; all specifications, design concepts,
documents and manuals; all security systems relating to the product or
procedures, including, without limitation, software security systems;

               (iii) Trade secrets, production processes, marketing techniques,
mailing lists, purchasing information, price lists, pricing policies, quoting
procedures, financial information, customer and prospect names and requirements,
customer data, customer site information and other materials or information
relating to the manner in which Employer does business;

               (iv)  Discoveries, concepts and ideas, whether or not patentable

similar businesses or activities;

               (vi)  Any other material or information that has been created,
discovered or developed, or otherwise becomes known to Employer which has
commercial value in the business in which Employer is engaged; and

               (vii) All ideas which are derived from or relate to Employee's
access to or knowledge of any of the above-enumerated materials and information.

     Failure to mark any of the Proprietary Information as confidential shall
not affect its status as part of the Proprietary Information under the terms of
this Agreement.

     3.   Ownership of Information.
          ------------------------

          (i)   Employee hereby assigns to Employer all of Employee's right,
title and interest in any idea (whether or not patentable or protectable by
copyright), product, invention, discovery, computer software program or other
computer-related equipment or technology, conceived or developed in whole or in
part, or in which Employee may have aided in its development, while employed by
Employer, including, without limitation, any Proprietary Information. If any one
or more of the aforementioned are deemed in any way to fall within the
definition of "work made for hire", as such term is defined in 17 U.S.C. (S)
101, such work shall be considered "work made for hire", the copyright of which
shall be owned solely, completely and exclusively by Employer. If any of the
aforementioned are considered to be work not included in the categories of work
covered by the "work made for hire" definition contained in 17 U.S.C. (S) 101,
such work shall be

                                                                               9
<PAGE>

owned solely by, or assigned or transferred completely and exclusively to,
Employer. Employee agrees to execute any instruments and to do all other things
reasonably requested by Employer (both during and after Employee's employment
with Employer) in order to more fully vest in Employer all ownership rights in
those items thereby transferred by Employee to Employer. Employee further agrees
to disclose immediately to Employer all Proprietary Information conceived of or
developed in whole or in part by him during the term of his employment with
Employer and to assign to Employer any right, title or interest he may have in
such Proprietary Information.

          (ii)  Employee hereby represents and warrants that Employee has fully
disclosed to Employer on Schedule A hereto any idea, invention, product,
                         ----------
improvement, computer software program or other equipment or technology related
to therapeutic pharmaceuticals (an "Invention") not covered in Section 3(i)
above which, prior to his employment with Employer, Employee conceived of or
developed, wholly or in part, and in which Employee has any right, title or
proprietary interest and which directly relate to Employer's business, but which
has not been published or filed with the United States Patent or Copyright
Offices or assigned or transferred to Employer. If there is no such list of
Schedule A, Employee represents that Employee has made no such Inventions at the
- ----------
time of signing this Agreement or Employee hereby assigns such Inventions to
Employer.

          (iii) Notwithstanding anything in this Agreement to the contrary, the
obligation of Employee to assign or offer to assign his rights in an Invention
to Employer shall not extend or apply to an Invention that Employee developed
entirely on his own time without using Employer's equipment, supplies, facility
or trade secret information unless such Invention (a) relates to Employer's
business or actual or demonstrably anticipated research or development, or (b)
results from any work performed by Employee for Employer. Employee shall bear
the burden of proof in establishing that his Invention qualifies for exclusion
under this Section 3(iii). With respect to Section 3(iii), it is agreed and
acknowledged that during Employee's employment, Employer may enter other lines
of business, which are related or unrelated to its current lines of business, in
which case this Agreement would be expanded to cover such new lines of business.

     4.   Injunctive Relief.  Employee understands and agrees that Employer will
          -----------------
suffer irreparable harm in the event that Employee breaches any of his
obligations under this Agreement and that monetary damages will be inadequate to
compensate Employer for such breach. Accordingly, Employee agrees that, in the
event of a breach or threatened breach by Employee of any of the provisions of
this Agreement, Employer, in addition to and not in limitation of any other
rights, remedies or damages available to Employer at law or in equity, shall be
entitled to a permanent injunction in order to prevent or to restrain any such
breach by Employee, or any of employee's partners, agents, representatives,
servants, employers, employees and/or any and all persons directly or indirectly
acting for or with him.

     5.   Records.  All notes, data, tapes, reference materials, sketches,
          -------
drawings, memoranda, models and records in any way relating to any of the
information referred to

                                                                              10
<PAGE>

in Sections 1, 2 and 3 hereof (including, without limitation, any Proprietary
Information) or to Employer's business shall belong exclusively to Employer, and
Employee agrees to turn over to Employer all such materials and all copies of
such materials in his possession or then under his control at the request of
Employer or, in the absence of such a request, upon the termination of
Employee's employment with Employer.

     6.   Accounting for Profits.  Employee covenants and agrees that, if he
          ----------------------
shall violate any of his covenants or agreements under this Agreement, Employer
shall be entitled to an accounting and repayment of all profits, compensation,
commissions, remunerations or benefits which Employee directly or indirectly has
realized and/or may realize as a result of, growing out of or in connection with
any such violation; such remedy shall be in addition to and not in limitation of
any injunctive relief or other rights or remedies to which Employer is or may be
entitled at law, in equity or under this Agreement.

     7.   Covenant Not to Compete.  It is recognized and understood by the
          -----------------------
parties hereto that Employee, through Employee's association with Employer as an
employee, shall acquire a considerable amount of knowledge and goodwill with
respect to the business of Employer, which knowledge and goodwill are extremely
valuable to Employer and which would be extremely detrimental to Employer if
used by Employee to compete with Employer. It is, therefore, understood and
agreed by the parties hereto that, because of the nature of the business of
Employer, it is necessary to afford fair protection to Employer from such
competition by Employee. Consequently, as a material inducement to employ
Employee in the aforementioned positions, Employee covenants and agrees to the
following:

          (a) Except as otherwise approved in writing by Employer, Employee
agrees:

              (i)   that Employee will not, directly or indirectly, with or
through any family member or former director, officer or employee of Employer,
or acting along or as a member of a partnership or as an officer, holder of or
investor in as much as 5% of any security of any class, director, employee,
consultant or representative of any corporation or other business entity:

              (ii)  at any time while engaged as an employee of Employer and for
a period of one (1) year following termination as an employee, interfere with,
or seek to interfere with, the relationship between Employer or any affiliate of
Employer and the following: (a) any of the employees of such entities; (b) any
of the customers of such entities then existing or existing at any time within
three (3) years prior to termination of Employee's employment by Employer; or
(c) any of the suppliers of such entities then existing or existing at any time
within three (3) years prior to termination of Employee's employment by
Employer.

          (b) The parties hereto agree that in the event that either the length
of time or the geographic area set forth in paragraph (a) is deemed too
restrictive in any

                                                                              11
<PAGE>

court proceeding, that the court may reduce such restrictions to those which it
deems reasonable under the circumstances.

          (c) Employee agrees and acknowledges that Employer does not have any
adequate remedy at law for the breach or threatened breach by him of this
covenant and agrees that Employer may in addition to the other remedies which
may be available to it under this Agreement, file a suit in equity to enjoin
Employee from such breach or threatened breach.


     8.   Reasonableness of Restrictions.
          ------------------------------

          (a) Employee has carefully read and considered the provisions of
Sections 1 through 7 hereof and, having done so, agrees that the restrictions
set forth therein are fair and reasonable and are reasonably required for the
protection of the interests of Employer, its officers, directors, stockholders
and employees.

          (b) In the event that, notwithstanding the foregoing, any part of the
covenants set forth in Sections 1 through 7 hereof shall be held to be invalid
and unenforceable, the court so deciding may reduce or limit the terms of such
provision to allow such provision to be enforced.

     9.   Burden and Benefit.  This Agreement shall be binding upon, and shall
          ------------------
inure to the benefit of, Employer and Employee, and their respective heirs,
personal and legal representatives, and, in the case of Employer, its successors
and assigns.

     10.  Governing Law.  In view of the fact that the principal office of
          -------------
Employer is located in the State of North Carolina, it is understood and agreed
that the construction and interpretation of this Agreement shall at all times
and in all respects be governed by the laws of the State of North Carolina.

     11.  Severability.  The provisions of this Agreement shall be deemed
          ------------
severable, and the invalidity or unenforceability of any one or more of the
provisions hereof shall not affect the validity or enforceability of the other
provisions hereof.

     12.  Employer.  As used herein, the term "Employer" shall also include any
          --------
corporation which is at any time the parent or a subsidiary of Employer, or any
corporation or entity which is an affiliate of Employer by virtue of common
(although not identical) ownership, and for which Employee is providing services
in any form during his employment with Employer or any such other corporation or
entity.

     13.  Notices.  Any notice required to be given hereunder shall be
          -------
sufficient if in writing, and sent by certified or registered mail, return
receipt requested, first-class postage prepaid, in the case of Employee, to his
address as shown on Employer's records, and in the case of Employer, to its
principal office in the State of North Carolina.

                                                                              12
<PAGE>

     14.  Entire Agreement.  This Agreement contains the entire agreement and
          ----------------
understandings by and between Employer and Employee with respect to the
covenants herein described, and no representations, promises, agreements or
understandings, written or oral, not herein contained shall be of any force or
effect. Nothing contained in this Agreement shall be deemed or construed to
constitute an agreement by Employer to employ or continue to employ Employee. No
change or modification hereof shall be valid or binding unless the same is in
writing and signed by the parties hereto. No waiver of any provision of this
Agreement shall be valid unless the same is in writing and signed by the party
against whom such waiver is sought to be enforced; moreover, no valid waiver of
any provision of this Agreement at any time shall be deemed a waiver of any
other provision of this Agreement at such time nor will it be deemed a valid
waiver of such provision at any other time.

     15.  Headings.  The headings and other captions in this Agreement are for
          --------
convenience and reference only and shall not be used in interpreting, construing
or enforcing any of the provisions of this Agreement.

     16.  Effective Date.  This Agreement shall be effective as of the April 1,
          --------------
1999.




     IN WITNESS WHEREOF, Employer and Employee have duly executed this Agreement
as of the day and year first above written.

                                  POZEN INC.

                           INVESTOR RIGHTS AGREEMENT

     This Investor Rights Agreement (the "Agreement") is entered into as of July
28, 1999, by and among, POZEN Inc., a Delaware corporation (the "Company"), the
holders of the Company's Series D Preferred Stock listed on Exhibit A attached
                                                            ---------
hereto (the "Investors"), and those persons listed on Exhibit B attached hereto
                                                      ---------
(each individually a "Common Holder" and, collectively, the "Common Holders").

     WHEREAS, in connection with the issuance and sale of shares of Company's
Series D Preferred Stock (the "Series D Stock") to the Investors pursuant to
that certain Series D Preferred Stock Purchase Agreement, dated as of the date
hereof, by and between the Company and the Investors (the "Series D Agreement"),
the Company desires to provide the Investors certain rights with respect to
registration of the shares of stock held by them and certain other rights with
respect to such shares as an inducement to the Investors to purchase shares of
the Series D Stock;

     NOW, THEREFORE, in consideration of the mutual agreements, covenants and
conditions contained herein, the Company, the Investors and the Common Holders
hereby agree as follows.

                                  Section 1.

                           RESTRICTIONS ON TRANSFER
                           ------------------------

     1.1  Restrictive Legend.  Each certificate representing (i) the Series D
          ------------------
Stock, (ii) the Common Stock of the Company (the "Common Stock") issued upon
conversion of the Series D Stock, and (iii) any other securities issued in
respect of the Series D Stock or Common Stock issued upon conversion of the
Series D Stock upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of Section 1.2 below) be stamped or otherwise imprinted with a legend
in substantially the following form (in addition to any legend required under
applicable state securities laws).

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT
     WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, MORTGAGED,
     PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE
     REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF
     1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR THE
     AVAILABILITY OF AN EXEMPTION FROM THE REGISTRATION PROVISIONS OF THE
     SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS.
     COPIES OF THE STOCK PURCHASE AGREEMENT AND INVESTOR RIGHTS AGREEMENT
<PAGE>

     PROVIDING FOR RESTRICTIONS ON TRANSFER OF THESE SECURITIES MAY BE OBTAINED
     UPON WRITTEN REQUEST BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
     SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
     CORPORATION."

     Each Holder (as defined below) consents to the Company's making a notation
on its records and giving instructions to any transfer agent of the Series D
Stock or the Common Stock in order to implement the restrictions on transfer
established in this Section 1. Such legend shall be removed by the Company from
any certificate at such time as the holder of the shares represented by the
certificate satisfies the requirements of Rule 144(k) under the Securities Act
of 1933, as amended (the "1933 Act"), provided that Rule 144(k) as then in
effect does not differ substantially from Rule 144(k) as in effect as of the
date of this Agreement, and provided further that the Company has received from
the Holder a written representation that (i) such Holder is not an affiliate of
the Company and has not been an affiliate during the preceding three months,
(ii) such Holder has beneficially owned the shares represented by the
certificate for a period of at least two years, (iii) such Holder otherwise
satisfies the requirements of Rule 144(k) as then in effect with respect to such
shares, and (iv) such Holder will submit the certificate for any such shares to
the Company for reapplication of the legend at such time as the holder becomes
an affiliate of the Company or otherwise ceases to satisfy the requirements of
Rule 144(k) as then in effect.

     1.2  Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------
representing Registrable Securities (as defined below) by acceptance thereof
agrees to comply in all respects with the provisions of this Section 1.2. Prior
to any proposed sale, assignment, transfer or pledge of any Registrable
Securities, unless there is in effect a registration statement under the 1933
Act covering the proposed transfer, the holder thereof shall give written notice
to the Company of such holder's intention to effect such transfer, sale,
assignment or pledge. Each such notice shall describe the manner and
circumstances of the proposed transfer, sale, assignment or pledge in sufficient
detail, and shall be accompanied at such holder's expense by either (i) a
written opinion of legal counsel who shall, and whose legal opinion shall, be
reasonably satisfactory to the Company addressed to the Company, to the effect
that the proposed transfer of the Registrable Securities may be effected without
registration under the 1933 Act or (ii) a "no action" letter from the SEC to the
effect that the transfer of such securities without registration will not result
in a recommendation by the staff of the Securities and Exchange Commission (the
"SEC") that action be taken with respect thereto, whereupon the holder of such
Registrable Securities shall be entitled to transfer such Registrable Securities
in accordance with the terms of the notice delivered by the holder to the
Company.  The Company will not require such a legal opinion or "no action"
letter (a) in any transaction in compliance with Rule 144, or (b) in any
transaction in which an Investor that is a partnership, limited liability
company or corporation distributes Series D Stock or Common Stock issuable upon
conversion thereof after six months after the purchase of such securities
hereunder solely to partners, members or stockholders (as the case may be)
thereof for no consideration, provided that each transferee agrees in writing to
be subject to the terms of this Section 1.2.  Each certificate evidencing the
Registrable Securities transferred as above provided shall bear, except if such
transfer is made pursuant to Rule 144, the appropriate restrictive legend set
forth in Section 1.1 above, except that such certificate shall not

                                       2
<PAGE>

bear such restrictive legend if in the opinion of counsel for such holder and
the Company such legend is not required in order to establish compliance with
any provisions of the 1933 Act.

                                  Section 2.

                              REGISTRATION RIGHTS
                              -------------------

     The Company hereby grants to each of the Holders (as defined below) the
registration rights set forth in this Section 2, with respect to the Registrable
Securities (as defined below) owned by such Holders.  The Company and the
Holders agree that the registration rights provided herein set forth the sole
and entire agreement, and supersede any prior agreement, between the Company and
the Holders with respect to registration rights for the Company's securities.

     2.1  Certain Definitions.  As used in this Section 2:
          -------------------

          (a) The terms "register," "registered" and "registration" refer to a
registration effected by filing with the SEC a registration statement (the
"Registration Statement") in compliance with the 1933 Act, and the declaration
or ordering by the SEC of the effectiveness of such Registration Statement.

          (b) The term "Registrable Securities" means (i) Common Stock issued or
issuable upon conversion of the shares of Series D Stock held by Investors or
any transferee as permitted by Section 2.8 hereof, and (ii) any Common Stock
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security that is issued as) a dividend or other distribution with respect
to, or in exchange or in replacement of, such Registrable Securities; provided,
however, that shares of Common Stock or other securities shall only be treated
as Registrable Securities if and so long as (A) they have not been sold to or
through a broker or dealer or underwriter in a public distribution or a public
securities transaction, (B) they have not been sold in a transaction exempt from
the registration and prospectus delivery requirements of the 1933 Act under
Section 4(1) thereof so that all transfer restrictions and restrictive legends
with respect thereto are removed upon the consummation of such sale, and (C) the
registration rights associated with such securities have not been terminated
pursuant to Section 2.16 hereof.

          (c) The term "Holder" (collectively, "Holders") means each Investor
and any transferee, as permitted by Section 2.8 hereof, holding Registrable
Securities, securities exercisable or convertible into Registrable Securities or
securities exercisable for securities convertible into Registrable Securities.

          (d) The term "Initiating Holders" means any Holder or Holders of at
least fifty percent (50%) of the Registrable Securities then outstanding and not
registered at the time of any request for registration made pursuant to Section
2.2 of this Agreement.

                                       3

     2.2  Demand Registration.
          -------------------

          (a)  Demand for Registration. If the Company shall receive from
               -----------------------
Initiating Holders a written demand that the Company effect any registration (a
"Demand Registration") of at least 25% of the Registrable Securities (other than
a registration on Form S-3 or any related form of registration statement, such a
request being provided for under Section 2.9 hereof) having an aggregate
offering amount, net of underwriting discounts and commissions, in excess of
$10,000,000, the Company will:

               (i)  promptly (but in any event within 10 days) give written
notice of the proposed registration to all other Holders; and

               (ii) use its best efforts to effect such registration as soon as
practicable and as will permit or facilitate the sale and distribution of all or
such portion of such Initiating Holders' Registrable Securities as are specified
in such demand, together with all or such portion of the Registrable Securities
of any Holder or Holders joining in such demand as are specified in a written
demand received by the Company within 15 days after such written notice is
given, provided that the Company shall not be obligated to take any action to
effect any such registration pursuant to this Section 2.2:

                    (A)  in any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                    (B)  after the Company has effected one (1) such
registration pursuant to this Section 2.2 and the sales of the shares of Common
Stock under such registration have closed;

                    (C)  if the Company shall furnish to such Holders a
certificate signed by the President of the Company, stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its stockholders for such Registration Statement
to be filed at the date filing would be required, in which case the Company
shall have an additional period or periods of not more than 90 days within which
to file such Registration Statement; provided, however, that the Company shall
not use this right to delay the filing for more than 180 days in the aggregate
in any 12-month period; or

                    (D)  prior to the earlier of (1) the second anniversary of
the date of this Agreement or (2) the date 180 days after the effective date of
the initial public offering of the Company's securities.

               (b)  Underwriting.  If reasonably required to maintain an orderly
                    ------------
market in the Common Stock, the Holders shall distribute the Registrable
Securities covered by their demand by means of an underwriting. If the
Initiating Holders intend to distribute the Registrable Securities covered by
their demand by means of an underwriting, they shall so advise the Company as
part of their demand made pursuant to this Section 2.2, including the identity
of

                                       4
<PAGE>

the managing underwriter; and the Company shall include such information in the
written notice referred to in Section 2.2(a)(i). In such event, the right of any
Holder to registration pursuant to this Section 2.2 shall be conditioned upon
such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein.

     The Company shall, together with all holders of capital stock of the
Company proposing to distribute their securities through such underwriting,
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected by a majority-in-interest of the Initiating Holders and
reasonably satisfactory to the Company. Notwithstanding any other provision of
this Section 2.2, if the underwriter shall advise the Company that marketing
factors (including, without limitation, an adverse effect on the per share
offering price) require a limitation of the number of shares to be underwritten,
then the Company shall so advise all Holders of Registrable Securities that have
requested to participate in such offering, and the number of shares of
Registrable Securities that may be included in the registration and underwriting
shall be allocated pro rata among such Holders thereof in proportion, as nearly
as practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the Registration Statement.  No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

     If any Holder disapproves of the terms of the underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company, the underwriter
and the Initiating Holders. The Registrable Securities so withdrawn shall also
be withdrawn from registration.

     If the underwriter has not limited the number of Registrable Securities to
be underwritten, the Company may include securities for its own account (or for
the account of other stockholders) in such registration if the underwriter so
agrees and if the number of Registrable Securities would not thereby be limited.

     2.3  Piggyback Registration.
          ----------------------

          (a)  Company Registration.  If at any time or from time to time the
               --------------------
Company shall determine to register any of its securities, either for its own
account or for the account of security holders, other than a registration
relating solely to employee benefit plans, a registration on Form S-4 relating
solely to an SEC Rule 145 transaction or a registration pursuant to Section 2.2
or 2.9 hereof, the Company will:

               (i)  promptly (but in any event within 10 days) give to each
Holder written notice thereof; and

               (ii) include in such registration (and any related qualification
under state securities laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 15 days after receipt of such written notice from the
Company, by any Holder or Holders, except as set forth in Section 2.3(b) below.

                                       5
<PAGE>

     Such Registrable Securities shall only be included to the extent that
inclusion will not diminish the number of securities included by the Company.

          (b)  Underwriting.  If the registration of which the Company gives
               ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 2.3(a)(i). In such event the right of any Holder to
registration pursuant to this Section 2.3 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.

     All Holders proposing to distribute their Registrable Securities through
such underwriting shall, together with the Company and the other parties
distributing their securities through such underwriting, enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of this Section 2.3, if the underwriter determines that marketing
factors require a limitation of the number of shares to be underwritten, the
underwriter may limit the number of Registrable Securities to be included in the
registration and underwriting, or may exclude Registrable Securities entirely
from such registration and underwriting subject to the terms of this Section
2.3. The Company shall so advise all holders of the Company's securities that
would otherwise be registered and underwritten pursuant hereto, and the number
of shares of such securities, including Registrable Securities, that may be
included in the registration and underwriting shall be allocated in the
following manner: shares, other than Registrable Securities and other securities
that have contractual rights with respect to registration similar to those
provided for in this Section 2.3, requested to be included in such registration
by stockholders shall be excluded, and if a limitation on the number of shares
is still required, the number of Registrable Securities and other securities
that have contractual rights with respect to registration that may be included
shall be allocated among the holders thereof in proportion, as nearly as
practicable, to the amounts of Registrable Securities and such other securities
with such contractual rights held by each such holder at the time of filing the
Registration Statement. For purposes of any such underwriter cutback, all
Registrable Securities and other securities held by any holder that is a
partnership, limited liability company or corporation shall also include any
Registrable Securities held by the partners, retired partners, members,
stockholders or affiliated entities of such holder, or the estates and family
members of any such partners, retired partners, members and any trusts for the
benefit of any of the foregoing persons, and such holder and other persons shall
be deemed to be a single "selling holder," and any pro rata reduction with
respect to such "selling holder" shall be based upon the aggregate amount of
shares carrying registration rights owned by all entities and individuals
included in such "selling holder", as defined in this sentence. No securities
excluded from the underwriting by reason of the underwriters marketing
limitation shall be included in such registration. Nothing in this Section
2.3(b) is intended to diminish the number of securities to be included by the
Company in the underwriting.

     If any Holder disapproves of the terms of the underwriting, it may elect to
withdraw therefrom by written notice to the Company and the underwriter. The
Registrable Securities so withdrawn shall also be withdrawn from registration.

          (c)  Right to Terminate Registration. The Company shall have the right
               -------------------------------
to

                                       6
<PAGE>

terminate or withdraw any registration initiated by it under this Section 2.3
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration.

     2.4  Expenses of Registration.  All expenses incurred in connection with
          ------------------------
all registration effected pursuant to Sections 2.2, 2.3 and 2.9, including
without limitation all registration, filing and qualification fees (including
state securities law fees and expenses), printing expenses, escrow fees, fees
and disbursements of counsel for the Company and expenses of any special audits
incidental to or required by such registration shall be borne by the Company;
provided, however, that the Company shall not be required to pay stock transfer
taxes or underwriters' discounts or selling commissions relating to Registrable
Securities; and provided, further, that the Company shall not be required to pay
for any expenses of any registration pursuant to Section 2.9 after the Company
has effected two (2) registrations pursuant to Section 2.9 or any registration
pursuant to Section 2.2 after the Company has effected one (1) registration
pursuant to Section 2.2, in which event the Holders of Registrable Securities to
be registered shall bear all such expenses pro rata on the basis of Registrable
Securities to be registered.  Notwithstanding anything to the contrary above,
the Company shall not be required to pay for any expenses of any registration
proceeding under Section 2.2 if the registration request is subsequently
withdrawn at the request of the Holders of a majority of the Registrable
Securities to have been registered, in which event the Holders of Registrable
Securities to have been registered shall bear all such expenses pro rata on the
basis of the Registrable Securities to have been registered. Notwithstanding the
preceding sentence, however, if at the time of the withdrawal, the Holders have
learned of a materially adverse change in the condition, business or prospects
of the Company from that known to the Holders at the time of their request, then
the Holders shall not be required to pay any of said expenses and shall retain
their rights pursuant to Section 2.2.

     2.5  Obligations of the Company.  Whenever required under this Section 2 to
          --------------------------
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a)  prepare and file with the SEC a Registration Statement with
respect to such Registrable Securities and use its diligent efforts to cause
such Registration Statement to become effective, and keep such Registration
Statement effective for the lesser of 180 days or until the Holder or Holders
have completed the distribution relating thereto provided however that the
Company shall have the right to terminate such Registration Statement, or to
place a stop-transfer order with respect to the shares for which registration
has been requested thereunder, upon notice to the participating Holders to the
extent necessary, in the sole discretion of the Company upon the advice of
counsel, to avoid any requirement that the Company disclose material, nonpublic
information, the disclosure of which would be seriously detrimental to the
Company and its stockholders.

          (b)  prepare and file with the SEC such amendments and supplements to
such Registration Statement and the prospectus used in connection with such
Registration Statement as may be necessary to keep such Registration Statement
effective and to comply with the

                                       7
<PAGE>

provisions of the 1933 Act with respect to the disposition of all securities
covered by such registration statement.

          (c)  furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

          (d)  use its diligent efforts to register or otherwise qualify the
securities covered by such Registration Statement under such other securities
laws of such states and other jurisdictions as shall be reasonably requested by
the Holders or the managing underwriter, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such states
or jurisdictions.

          (e)  in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f)  notify each Holder of Registrable Securities covered by such
Registration Statement, at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act, of the happening of any event as a
result of which the prospectus included in such Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

          (g)  use its diligent efforts to list the Registrable Securities
covered by such Registration Statement with any securities exchange on which the
Common Stock is then listed.

          (h)  make available for inspection by each Holder including
Registrable Securities in such registration, any underwriter participating in
any distribution pursuant to such registration, and any attorney, accountant or
other agent retained by such Holder or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, as such
parties may reasonably request, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such Holder,
underwriter, attorney, accountant or agent in connection with such Registration
Statement.

          (i)  cooperate with Holders including Registrable Securities in such
registration and the managing underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold, such certificates to be in such denominations and registered in such
names as such Holders or the managing underwriters may request at least two
business days prior to any sale of Registrable Securities.

          (j)  permit any Holder, which Holder, in the sole and exclusive
judgment, exercised in good faith, of such Holder, might be deemed to be a
controlling person of the

                                       8
<PAGE>

Company, to participate in good faith in the preparation of such Registration
Statement and to require the insertion therein of material, furnished to the
Company in writing, that in the reasonable judgment of such Holder and its
counsel should be included.

     2.6  Indemnification.
          ---------------

          (a)  The Company will, and does hereby undertake to, indemnify and
hold harmless each Holder of Registrable Securities, each of such Holder's
officers, directors, managers, partners, members and agents, and each person
controlling such Holder, with respect to any registration, qualification or
compliance effected pursuant to this Section 2, and each underwriter, if any,
and each person who controls any underwriter, of the Registrable Securities held
by or issuable to such Holder, against all claims, losses, damages and
liabilities (or actions in respect thereto) to which they may become subject
under the 1933 Act, the Securities Exchange Act of 1934, as amended (the "1934
Act"), or other federal or state law arising out of or based on (i) any untrue
statement (or alleged untrue statement) of a material fact contained in any
prospectus, offering circular or other similar document (including any related
Registration Statement, notification, or the like) incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances in which they were made, (ii) any violation or alleged violation
by the Company of any federal, state or common law rule or regulation applicable
to the Company in connection with any such registration, qualification or
compliance, or (iii) any failure to register or qualify Registrable Securities
in any state where the Company or its agents have affirmatively undertaken or
agreed in writing that the Company (the undertaking of any underwriter chosen by
the Company being attributed to the Company) will undertake such registration or
qualification on behalf of the Holders of such Registrable Securities (provided
that in such instance the Company shall not be so liable if it has undertaken
its best efforts to so register or qualify such Registrable Securities) and will
reimburse, as incurred, each such Holder, each such underwriter and each such
director, manager, officer, partner, member, agent and controlling person, for
any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action;
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission made in conformity with written information
furnished to the Company by an instrument duly executed by such Holder or
underwriter and stated to be specifically for use therein.

                                       9
<PAGE>

          (b)  Each Holder will, and if Registrable Securities held by or
issuable to such Holder are included in such registration, qualification or
compliance pursuant to this Section 2, does hereby undertake to indemnify and
hold harmless the Company, each of its directors and officers, and each person
controlling the Company, each underwriter, if any, and each person who controls
any underwriter, of the Company's securities covered by such a Registration
Statement, and each other Holder, each of such other Holder's officers,
directors, managers, partners, members and agents and each person controlling
such other Holder, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on (i) any failure of such
Holder or its agents or representatives to comply with the prospectus delivery
requirements of the 1933 Act or any other applicable securities or Blue Sky law,
or (ii) any untrue statement (or alleged untrue statement) of a material fact
contained in any such Registration Statement, prospectus, offering circular or
other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances in which they were made,
and will reimburse, as incurred, the Company, each such underwriter, each such
other Holder, and each such director, officer, manager, partner, member and
controlling person of the foregoing, for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) was made in such Registration Statement,
prospectus, offering circular or other document, in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein;
provided, however, that the liability of each Holder hereunder (unless such
Holder's liability hereunder is based upon such Holder's willful misconduct as
determined by the nonappealable final decision of a court) shall be limited to
the proportion of any such claim, loss, damage or liability that is equal to the
proportion that the public offering price of the shares sold by such Holder
under such Registration Statement bears to the total public offering price of
all securities sold thereunder, but in any event not to exceed the net proceeds
received by such Holder from the sale of securities under such Registration
Statement. It is understood and agreed that the indemnification obligations of
each Holder pursuant to any underwriting agreement entered into in connection
with any Registration Statement shall be limited to the obligations contained in
this subsection 2.6(b).

          (c)  Each party entitled to indemnification under this Section 2.6
(the "Indemnified Party") shall give notice to the party required to provide
such indemnification (the "Indemnifying Party") of any claim as to which
indemnification may be sought promptly after such Indemnified Party has actual
knowledge thereof, and shall permit the Indemnifying Party to assume the defense
of any such claim or any litigation resulting therefrom; provided that counsel
for the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be subject to approval by the Indemnified Party (whose
approval shall not be unreasonably withheld) and the Indemnified Party may
participate in such defense at the Indemnifying Party's expense if
representation of such Indemnified Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by such counsel in such proceeding; and provided further that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Section 2, except
to the extent that such failure to give notice shall materially adversely

                                       10
<PAGE>

affect the Indemnifying Party in the defense of any such claim or any such
litigation. An Indemnifying Party, in the defense of any such claim or
litigation, may, without the consent of each Indemnified Party, consent to entry
of any judgment or enter into any settlement that includes as an unconditional
term thereof the giving by the claimant or plaintiff therein, to such
Indemnified Party, of a release from all liability with respect to such claim or
litigation.

          (d)  In order to provide for just and equitable contribution to joint
liability under the 1933 Act in any case in which either (i) any Holder
exercising rights under this Agreement, or any controlling person of any such
Holder, makes a claim for indemnification pursuant to this Section 2.6 but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 2.6 provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 2.6; then, and in each such case,
the Company and such Holder will contribute to the aggregate claims, losses,
damages or liabilities to which they may be subject (after contribution from
others) in such proportion so that such Holder is responsible for the portion
represented by the percentage that the public offering price of the securities
offered by such Holder pursuant to the Registration Statement bears to the
public offering price of all securities offered by such Registration Statement,
and the Company will be responsible for the remaining portion (without prejudice
as to the Company's right to contributions from any other responsible parties);
provided, however, that, in any case, (A) no such Holder will be required to
contribute any amount in excess of the public offering price of all securities
offered by it pursuant to such Registration Statement, after deduction of
underwriting discounts and commissions (unless such Holder's liability hereunder
is based upon such Holder's willful misconduct as determined by the
nonappealable final decision of a court); and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11 (f) of the 1933
Act) will be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation.

          (e)  The indemnities provided in this Section 2.6 shall survive the
transfer of any Registrable Securities by such Holder.

     2.7  Information by Holder.  The Holder or Holders of Registrable
          ---------------------
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may reasonably request in writing and as
shall be required in connection with any registration, qualification or
compliance referred to in this Section 2.

     2.8  Transfer of Rights.  The rights contained in Section 2 hereof may be
          ------------------
assigned or otherwise conveyed to transferees or assignees of Registrable
Securities, who shall be considered a `"Holder" for purposes hereof, provided
that such transfer is effected in compliance with Section 1.2 hereof and such
transfer is a "Permitted Transfer" as defined herein.

     (b)  For purposes of this Agreement, a "Permitted Transfer" shall mean: (i)
a transaction not involving a change in beneficial ownership; (ii) transactions
involving

                                       11
<PAGE>

distribution without consideration by a stockholder that is a partnership,
limited liability company or corporation to any of its partners, members or
stockholders (as the case may be), retired partners, members or stockholders, or
to the estate of any of its partners, members or stockholders; (iii) transaction
involving distribution without consideration by a stockholder that is a
corporation to any of its stockholders; (iv) transfers by any stockholder who is
an individual to a trust for the benefit of such stockholder or his family; (v)
a transfer in which the transferee acquires at least 50,000 shares of
Registrable Securities, subject to adjustments for combinations, consolidations,
recapitalizations, stock splits, stock dividends and the like; or (vi) transfers
by gift, will or intestate succession to the spouse, lineal descendants or
ancestors of any stockholder or spouse of a stockholder.

     2.9  Form S-3.  The Company shall use its diligent efforts to qualify for
          --------
registration on Form S-3 and to that end the Company shall register the Common
Stock under the 1934 Act within 12 months following the effective date of the
first registration of any securities of the Company on Form S-1.  After the
Company has qualified for the use of Form S-3 and the lapse of one year from the
closing of the Company's initial public offering, the Holders of Registrable
Securities shall have the right to request registrations on Form S-3 thereafter
under this Section 2.9. The Company shall give notice to all Holders of
Registrable Securities of the receipt of a request for registration pursuant to
this Section 2.9 and shall provide a reasonable opportunity for other Holders to
participate in the registration. Subject to the foregoing, the Company will use
its best efforts to effect as soon as practicable the registration of all shares
of Registrable Securities on Form S-3 to the extent requested by the Holder or
Holders thereof for purposes of disposition; provided, however, that the Company
shall not be obligated to effect any such registration (A) if the Holders,
together with the holders of any other securities of the Company entitled to
inclusion in such registration, propose to sell Registrable Securities and such
other securities (if any) at an aggregate price to the public of less than
$2,000,000 or (B) at any time when the Company has effected two (2)
registrations pursuant to this Section 2.9. Notwithstanding the foregoing,
nothing herein shall restrict, prohibit or limit in any way a Holder's ability
to exercise its registration rights under Sections 2.2 or 2.3 hereof.  The
Company shall have no obligation to take any action to effect any registration
pursuant to this Section 2.9 for any of the reasons set forth in Section
2.2(a)(ii)(A), (B), (C) or (D), (which shall be deemed to apply to the
obligations under this Section 2.9 with equal force). In addition, any
registration pursuant to this Section 2.9 shall be subject to the provisions of
Section 2.2(b), which shall be deemed to apply to the obligations under this
Section 2.9 with equal force, except that any reference therein to Section 2.2
or a subsection thereof shall, for these purposes only, be deemed to be a
reference to this Section 2.9.

     2.10 Delay of Registration.  No Holder shall have any right to obtain or
          ---------------------
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 2.

     2.11 Limitations on Subsequent Registration Rights.  From and after the
          ---------------------------------------------
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of at least a majority of the Registrable Securities then
outstanding and not registered, enter into any agreement with any holder or
prospective holder of any securities of the Company that would allow such holder
or prospective holder to (i) require the Company to effect a registration or
(ii)

                                       12
<PAGE>

include any securities in any registration filed under Section 2.2, 2.3 or 2.9
hereof, unless, under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of such securities will not diminish the amount of
Registrable Securities that are included in such registration.

     2.12 Rule 144 Reporting.  With a view to making available to the Holders
          ------------------
the benefits of certain rules and regulations of the SEC that may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its diligent efforts to:

          (a)  Make and keep current public information available, within the
meaning of SEC Rule 144 or any similar or analogous rule promulgated under the
1933 Act, at all times after it has become subject to the reporting requirements
of the 1934 Act;

          (b)  File with the SEC, in a timely manner, all reports and other
documents required of the Company under the 1933 Act and 1934 Act (after it has
become subject to such reporting requirements);

          (c)  So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time
commencing 90 days after the effective date of the first registration filed by
the Company for an offering of its securities to the general public), the 1933
Act and the 1934 Act (at any time after it has become subject to such reporting
requirements); a copy of the most recent annual or quarterly report of the
Company; and such other reports and documents as a Holder may reasonably request
in availing itself of any rule or regulation of the SEC allowing it to sell any
such securities without registration.

     2.13 "Market Stand-Off" Agreement.  Each Holder that is a "One Percent
           ---------------------------
Stockholder," as defined below, hereby agrees that during a period, not to
exceed 180 days, following the effective date of the initial, effective
registration statement of the Company filed under the 1933 Act, it shall not, to
the extent requested by the Company and any underwriter, sell, pledge, transfer,
make any short sale of, loan, grant any option for the purchase of, or otherwise
transfer or dispose of (other than to donees who agree to be similarly bound)
any Common Stock held by it at any time during such period except Common Stock
included in such registration; provided, however, that all other "One Percent
Stockholders" with registration rights (whether or not pursuant to this
Agreement) and all officers and directors of the Company enter into similar
agreements and such agreement shall be applicable only to the first such
registration statement of the Company that covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering.

     For purposes of this Section 2.13, the term "One Percent Stockholder" shall
mean a stockholder of the Company who holds at least one percent of the
outstanding Common Stock of the Company (assuming conversion of all outstanding
Series D Stock of the Company).

     In order to enforce the foregoing covenant, the Company may impose stop
transfer instructions with respect to the Registrable Securities of each Holder
(and the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

                                       13

     2.14  Amendment of Registration Rights. Any provision of this Section 2 may
           ---------------------------------
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least a majority of the
Registrable Securities then outstanding and not registered. Any amendment or
wavier effected in accordance with this Section shall be binding upon each
Holder, each future Holder of Registrable Securities and the Company.

     2.15  Inclusion of Stock Held by Common Holders.  In connection with any
           -----------------------------------------
registration effected pursuant to Section 2.3 hereof, the Common Holders shall
be entitled to include in such registration (on the same terms and conditions as
Holders selling their Registrable Securities in such registration) shares of
Common Stock held by such Common Holders; provided that any limitation by the
underwriter on the number of shares to be underwritten in connection with such
registration shall first be applied to the shares so included by such Common
Holders, as provided in Section 2.3(b), and provided further that each such
Common Holder's right to include shares of Common Stock in a registration
pursuant to this Section 2.15 is contingent upon such Common Holder's execution
of an indemnification and hold harmless agreement substantially in accordance
with Section 2.6(b) and an agreement to be bound by all other applicable
restrictions contained in this Section 2.

     2.16  Termination of Rights.  The rights of any particular Holder to cause
           ---------------------
the Company to register securities under Section 2.2, 2.3 or 2.9 hereof shall

dispose of all of its Registrable Securities in any 90-day period pursuant to
SEC Rule 144 (or any similar or analogous rule promulgated under the 1933 Act),
or (b) the fifth anniversary of the closing of the Company's initial public
offering of stock.

The Company hereby covenants and agrees as follows:

     3.1  Financial Information.
          ---------------------

          (a)  So long as any Investor or any subsidiary, affiliate or partner
of such Investor shall own at least 50,000 shares of Investor Stock or any

combinations, consolidations, recapitalizations, stock splits, stock dividends
and the like, the Company will furnish each Holder, subject to Section 3.1(b)
below, the following reports:

and in any event within 90 days thereafter, (1) audited consolidated balance
sheets of the Company and its subsidiaries, if any, as at the end of such fiscal
year, and audited consolidated statements of income and losses, stockholders'
equity and cash flows of the Company and its subsidiaries, if any, for such
fiscal year, prepared in accordance with generally accepted accounting

<PAGE>

and setting forth in each case in comparative form the figures for the previous
fiscal year, if any, all in reasonable detail and accompanied by a report and
opinion thereon by independent auditors selected by the Company's Board of
Directors; and (2) a copy of such auditors' management letter prepared in
connection therewith, if any, (as soon as such management letter is available,
which may be greater than the aforesaid 90-day period);

               (ii)  As soon as practicable after the end of each of the first
three quarters of the fiscal year, but in any event within 45 days after the end
of each such quarter, the unaudited consolidated balance sheets of the Company
and its subsidiaries, if any, as of the end of such quarter, and its unaudited
consolidated statements of income and losses, stockholders' equity and cash
flows for such quarter, setting forth in each case in comparative form the
figures for the corresponding period of the preceding fiscal year, all in
reasonable detail and prepared in accordance with generally accepted accounting
principles, except that such financial statements may not contain notes and will
be subject to year-end adjustment, and certified by the principal financial or
accounting officer of the Company. Such quarterly report shall include a
narrative, summary description of the Company's operations for such quarter,
indicating whether the Company is materially in compliance with this Agreement
and other material agreements and discussing any material variances from the
Company's operating plan; and

               (iii) With reasonable promptness, such other information
respecting the business, properties or the condition or operations, financial or
other, of the Company or any subsidiary as any Holder may from time to time
reasonably request.

          (b) The Company shall not be obligated pursuant to this Section 3.1 to
provide financial information to any person whom the Company reasonably believes
is a competitor of the Company.

          (c) The rights granted pursuant to this Section 3.1 may not be
assigned or otherwise conveyed by any Investor or by any subsequent transferee
of any such rights without the written consent of the Company, which consent
shall not be unreasonably withheld; provided that the Company may refuse such
written consent if the proposed transferee is reasonably believed by the Company
to be a competitor of the Company.

     3.2  Inspection.  The Company shall permit each Investor and each
          ----------
transferee in a Permitted Transfer (as defined in Section 2.8(b) hereof)
(provided such transfer is effected in compliance with Section 1.2 hereof), its
attorney or its other representative to visit and inspect the Company's
properties, to examine the Company's books of account and other records, to make
copies or extracts therefrom and to discuss the Company's affairs, finances and
accounts with its officers, management, employees and independent auditors all
at such reasonable times and as often as such Investor or transferee may
reasonably request; provided, however, that the Company shall not be obligated
pursuant to this Section 3.2 to provide trade secrets or confidential
information or to provide information to any person whom the Company reasonably
believes is a competitor of the Company; provided, further, that such Investor
shall bear any costs or expenses of such investigations or inquiries.

that, if unpaid, might become a lien or charge upon any properties of the
Company or any subsidiary, provided that neither the Company nor any subsidiary
shall be required to pay any such tax, assessment, charge, levy or claim that is
being contested in good faith and by appropriate proceedings if the Company or
any subsidiary shall have set aside on its books sufficient reserves, if any,
with respect thereto;

          (b) Payment of Trade Debt.  Pay, and cause each subsidiary to pay,
              ---------------------

          (d) Preservation of Corporate Existence.  Preserve and maintain, and,
              -----------------------------------
unless the Company reasonably deems it not to be in its best interests, cause
each subsidiary to preserve and maintain, its corporate existence, rights,
franchises and privileges in the jurisdiction of its incorporation, and qualify
and remain qualified, and cause each subsidiary to qualify and remain qualified,
as a foreign corporation in each jurisdiction in which such qualification is
necessary or desirable in view of its business and operations or the ownership
or lease of its properties, except when the failure to be so qualified would not
have a material adverse effect on the Company and its subsidiaries taken as a
whole; provided that nothing in this Section 3.3(d) shall prohibit the Company
or any of its subsidiaries from engaging in a corporate transaction in
connection with the acquisition of another corporation or business entity by the
Company or one or more of its wholly owned subsidiaries by merger,
consolidation, share exchange, purchase of substantially all the assets or other
reorganization whereby the stockholders of the Company immediately prior to the
transaction own in the aggregate more than 50% of the voting power of the
Company or other surviving entity after the transaction;

          (e) Intellectual Property.  Secure, preserve and maintain, and cause

          (g) Records and Books of Account.  Keep, and cause each subsidiary to
              ----------------------------
keep, adequate records and books of account in which complete entries will be
made in accordance with generally accepted accounting principles consistently
applied, reflecting all financial transactions of the Company and any
subsidiary, and in which, for each fiscal year, all proper reserves for
depreciation, depletion, returns of merchandise, obsolescence, amortization,
taxes, bad debts and other purposes in connection with its business shall be
made;

          (h) Maintenance of Properties.  Maintain and preserve, and cause each

each subsidiary to comply, in all other material respects with the provisions of
ERISA and the Code, and the rules and regulations thereunder, which are
applicable to any such plan; provided further that neither the Company nor any

Company or any subsidiary;

          (j) Financings.  Promptly, fully and in detail, inform the Board of
              ----------

                                 MISCELLANEOUS
                                 -------------

     5.1  Governing Law.  This Agreement shall be governed by, and construed and
          -------------
interpreted in accordance with the laws of the State of Delaware as applied to
agreements among Delaware residents made and to be performed entirely within the
State of Delaware.

     5.2  Successors and Assigns.  Except as otherwise expressly provided
          ----------------------
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.

     5.3  Entire Agreement.  This Agreement constitutes the full and entire
          ----------------
understanding and agreement among the parties with regard to the subjects
hereof. Nothing in this Agreement, express or implied, is intended to confer
upon any party, other than the parties hereto and their successors and assigns,
any rights, remedies, obligations or liabilities under or by reason of this
Agreement, except as expressly provided herein.

     5.4  Severability.  Any invalidity, illegality or limitation of the
          ------------
enforceability with respect to any Holder of any one or more of the provisions
of this Agreement, or any part thereof, whether arising by reason of the law of
any such person's domicile or otherwise, shall in no way affect or impair the
validity, legality or enforceability of this Agreement with respect to any other
Holder. In case any provision of this Agreement shall be invalid, illegal or
unenforceable, it shall to the extent practicable, be modified so as to make it
valid, legal and enforceable and to retain as nearly as practicable the intent
of the parties, and the validity, legality, and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

     5.5  Amendment and Waiver.  Except as otherwise expressly provided herein,
          --------------------
any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance, either
retroactively or prospectively and either for a specified period of time or
indefinitely) with the written consent of the Company and the Investors, or
their transferees holding at least a majority of the shares of Series D Stock,
voting together as a single group (treated as if converted at the conversion
rate then in effect and including, for such purposes shares of Common Stock into
which any shares of Series D Stock shall have been converted that are held by a
Holder); provided, however, that no such amendment or waiver shall reduce the
aforesaid percentage of Series D Stock and Common Stock issued upon conversion
thereof, the holders of which are required to consent to any waiver or
supplemental agreement, without the consent of the holders of all of such Series
D Stock and Common Stock; provided, further, that any amendment to Section 2.14
(or to Section 2.3 that would affect the rights under Section 2.14) shall also
require the consent of the holders of at least a majority of the shares of
Common Stock issued to, or issuable upon exercise of options held by, the Common
Holders. Any amendment or waiver effected in accordance with this Section 5.5
shall be binding upon each Common Holder, each Investor and each transferee of
the Registrable Securities. Upon the effectuation of each such amendment or
waiver, the Company shall promptly give written notice thereof to the Investors
and Common Holders who have not

                                       19
<PAGE>

previously consented thereto in writing. Notwithstanding anything to the
contrary in this Section 5.5, the Company shall be entitled to include
additional purchasers of its Series D Stock pursuant to the Series D Agreement
as parties to this Agreement, and to treat such purchasers as "Investors" and
"Holders" hereunder, by amending Exhibit A attached hereto and providing such

- ---------

     5.6  Delays or Omissions.  No delay or omission to exercise any right,
          -------------------
power or remedy accruing to the Company, the Investors, or any transferees upon
any breach, default or noncompliance of the Investors or any transferee or the
Company under this Agreement, shall impair any such right, power or remedy, nor
shall it be construed to be a waiver of any such breach, default or
noncompliance, or any acquiescence therein, or of any similar breach, default or
noncompliance thereafter occurring. It is further agreed that any waiver,
permit, consent or approval of any kind or character on the part of the Company
or the Investors of any breach, default or noncompliance under this Agreement or
any waiver on the Company's or the Investors' part of any provisions or
conditions of this Agreement must be in writing and shall be effective only to
the extent specifically set forth in such writing and that all remedies, either
under this Agreement, by law, or otherwise afforded to the Company and the
Investors, shall be cumulative and not alternative.

          ------------

                                  POZEN INC.

                           INVESTOR RIGHTS AGREEMENT

     This Investor Rights Agreement (the "Agreement") is entered into as of
March 24, 2000, by and among POZEN Inc., a Delaware corporation (the "Company"),
the holders of the Company's Series E Preferred Stock listed on Exhibit A
                                                                ---------
attached hereto (the "Investors"), certain other holders of capital stock of the
Company listed on Exhibit A-1 attached hereto (the "Other Holders") and those
                  -----------
persons listed on Exhibit B attached hereto (each individually a "Common Holder"
                  ---------
and, collectively, the "Common Holders").

     WHEREAS, in connection with the issuance and sale of shares of Company's
Series E Preferred Stock (the "Series E Stock") to the Investors pursuant to
that certain Series E Preferred Stock Purchase Agreement, dated as of the date
hereof, by and between the Company and the Investors (the "Series E Agreement"),
the Company desires to provide the Investors certain rights with respect to
registration of the shares of stock held by them and certain other rights with
respect to such shares as an inducement to the Investors to purchase shares of
the Series E Stock;

     NOW, THEREFORE, in consideration of the mutual agreements, covenants and
conditions contained herein, the Company, the Investors and the Common Holders
hereby agree as follows.

                                  Section 1.

                           RESTRICTIONS ON TRANSFER
                           ------------------------

     1.1  Restrictive Legend.  Each certificate representing (i) the Series E
          ------------------
Stock, (ii) the Common Stock of the Company (the "Common Stock") issued upon
conversion of the Series E Stock, and (iii) any other securities issued in
respect of the Series E Stock or Common Stock issued upon conversion of the
Series E Stock upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of this Section 1.1. or Section 1.2 below) be stamped or otherwise
imprinted with a legend in substantially the following form (in addition to any
legend required under applicable state securities laws).

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT
     WITH A VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE SOLD, MORTGAGED,
     PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE
     REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF
     1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS, OR THE
     AVAILABILITY OF AN EXEMPTION FROM THE REGISTRATION PROVISIONS OF THE
     SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS.
     COPIES OF THE
<PAGE>

     STOCK PURCHASE AGREEMENT AND INVESTOR RIGHTS AGREEMENT PROVIDING FOR
     RESTRICTIONS ON TRANSFER OF THESE SECURITIES MAY BE OBTAINED UPON WRITTEN
     REQUEST BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
     CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION."

     Each Holder (as defined below) consents to the Company's making a notation
on its records and giving instructions to any transfer agent of the Series E
Stock or the Common Stock in order to implement the restrictions on transfer
established in this Section 1. Such legend shall be removed by the Company from
any certificate at such time as the holder of the shares represented by the
certificate satisfies the requirements of Rule 144(k) under the Securities Act
of 1933, as amended (the "1933 Act"), provided that Rule 144(k) as then in
effect does not differ substantially from Rule 144(k) as in effect as of the
date of this Agreement, and provided further that the Company has received from
the Holder a written representation that (i) such Holder is not an affiliate of
the Company and has not been an affiliate during the preceding three months,
(ii) such Holder has beneficially owned the shares represented by the
certificate for a period of at least two years, (iii) such Holder otherwise
satisfies the requirements of Rule 144(k) as then in effect with respect to such
shares, and (iv) such Holder will submit the certificate for any such shares to
the Company for reapplication of the legend at such time as the holder becomes
an affiliate of the Company or otherwise ceases to satisfy the requirements of
Rule 144(k) as then in effect.

     1.2  Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------
representing Registrable Securities (as defined below) by acceptance thereof
agrees to comply in all respects with the provisions of this Section 1.2. Prior
to any proposed sale, assignment, transfer or pledge of any Registrable
Securities, unless there is in effect a registration statement under the 1933
Act covering the proposed transfer, the holder thereof shall give written notice
to the Company of such holder's intention to effect such transfer, sale,
assignment or pledge. Each such notice shall describe the manner and
circumstances of the proposed transfer, sale, assignment or pledge in sufficient
detail, and shall be accompanied at such holder's expense by either (i) a
written opinion of legal counsel who shall, and whose legal opinion shall, be
reasonably satisfactory to the Company addressed to the Company, to the effect
that the proposed transfer of the Registrable Securities may be effected without
registration under the 1933 Act or (ii) a "no action" letter from the SEC to the
effect that the transfer of such securities without registration will not result
in a recommendation by the staff of the Securities and Exchange Commission (the
"SEC") that action be taken with respect thereto, whereupon the holder of such
Registrable Securities shall be entitled to transfer such Registrable Securities
in accordance with the terms of the notice delivered by the holder to the
Company.  The Company will not require such a legal opinion or "no action"
letter (a) in any transaction in compliance with Rule 144, or (b) in any
transaction in which an Investor that is a partnership, limited liability
company or corporation distributes Series E Stock or Common Stock issuable upon
conversion thereof after six months after the purchase of such securities
hereunder solely to partners, members or stockholders (as the case may be)
thereof for no consideration, provided that each transferee agrees in writing to
be subject to the terms of this Section 1.2.  Each certificate evidencing the
Registrable Securities transferred as above provided shall bear, except if such
transfer is made pursuant to Rule 144, the appropriate restrictive legend set
forth in Section 1.1 above, except that such certificate shall not

                                       2
<PAGE>

bear such restrictive legend if in the opinion of counsel for such holder and
the Company such legend is not required in order to establish compliance with
any provisions of the 1933 Act.

                                  Section 2.

                              REGISTRATION RIGHTS
                              -------------------

     The Company hereby grants to each of the Holders (as defined below) the
registration rights set forth in this Section 2, with respect to the Registrable
Securities (as defined below) owned by such Holders.  The Company and the
Holders agree that the registration rights provided herein set forth the sole
and entire agreement, and supersede any prior agreement, between the Company and
the Holders with respect to registration rights for the Company's securities.

     2.1  Certain Definitions.  As used in this Section 2:
          -------------------

          (a) The terms "register," "registered" and "registration" refer to a
registration effected by filing with the SEC a registration statement (the
"Registration Statement") in compliance with the 1933 Act, and the declaration
or ordering by the SEC of the effectiveness of such Registration Statement.

          (b) The term "Registrable Securities" means (i) Common Stock issued or
issuable upon conversion of the shares of Series E Stock held by Investors or
any transferee as permitted by Section 2.8 hereof, and (ii) any Common Stock
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security that is issued as) a dividend or other distribution with respect
to, or in exchange or in replacement of, such Registrable Securities; provided,
however, that shares of Common Stock or other securities shall only be treated
as Registrable Securities if and so long as (A) they have not been sold to or
through a broker or dealer or underwriter in a public distribution or a public
securities transaction, (B) they have not been sold in a transaction exempt from
the registration and prospectus delivery requirements of the 1933 Act under
Section 4(1) thereof so that all transfer restrictions and restrictive legends
with respect thereto are removed upon the consummation of such sale, and (C) the
registration rights associated with such securities have not been terminated
pursuant to Section 2.16 hereof.

          (c) The term "Holder" (collectively, "Holders") means each Investor
and any transferee, as permitted by Section 2.8 hereof, holding Registrable
Securities, securities exercisable or convertible into Registrable Securities or
securities exercisable for securities convertible into Registrable Securities.

          (d) The term "Initiating Holders" means any Holder or Holders of at
least fifty percent (50%) of the Registrable Securities then outstanding and not
registered at the time of any request for registration made pursuant to Section
2.2 of this Agreement.


     2.2  Demand Registration.
          -------------------

                                       3
<PAGE>

          (a) Demand for Registration. If the Company shall receive from
              -----------------------
Initiating Holders a written demand that the Company effect any registration (a
"Demand Registration") (other than a registration on Form S-3 or any related
form of registration statement, such a request being provided for under Section
2.9 hereof), the Company will:

              (i)   promptly (but in any event within 10 days) give written
notice of the proposed registration to all other Holders; and

              (ii)  use its best efforts to effect such registration as soon as
practicable and as will permit or facilitate the sale and distribution of all or
such portion of such Initiating Holders' Registrable Securities as are specified
in such demand, together with all or such portion of the Registrable Securities
of any Holder or Holders joining in such demand as are specified in a written
demand received by the Company within 15 days after such written notice is
given, provided that the Company shall not be obligated to take any action to
effect any such registration pursuant to this Section 2.2:

                    (A) in any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                    (B) after the Company has effected two (2) such
registrations pursuant to this Section 2.2 and the sales of the shares of Common
Stock under such registrations have closed;

                    (C) if the Company shall furnish to such Holders a
certificate signed by the President of the Company, stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its stockholders for such Registration Statement
to be filed at the date filing would be required, in which case the Company
shall have an additional period or periods of not more than 90 days within which
to file such Registration Statement; provided, however, that the Company shall
not use this right to delay the filing for more than 180 days in the aggregate
in any 12-month period; or

                    (D) prior to the earlier of (1) the second anniversary of
the date of this Agreement or (2) the date 180 days after the effective date of
the initial public offering of the Company's securities.

          (b) Underwriting.  If reasonably required to maintain an orderly
              ------------
market in the Common Stock, the Holders shall distribute the Registrable
Securities covered by their demand by means of an underwriting. If the
Initiating Holders intend to distribute the Registrable Securities covered by
their demand by means of an underwriting, they shall so advise the Company as
part of their demand made pursuant to this Section 2.2, including the identity
of the managing underwriter; and the Company shall include such information in
the written notice referred to in Section 2.2(a)(i). In such event, the right of
any Holder to registration pursuant to this Section 2.2 shall be conditioned
upon such Holder's participation in such underwriting and

                                       4
<PAGE>

the inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.

     The Company shall, together with all holders of capital stock of the
Company proposing to distribute their securities through such underwriting,
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected by a majority-in-interest of the Initiating Holders and
reasonably satisfactory to the Company. Notwithstanding any other provision of
this Section 2.2, if the underwriter shall advise the Company that marketing
factors (including, without limitation, an adverse effect on the per share
offering price) require a limitation of the number of shares to be underwritten,
then the Company shall so advise all Holders of Registrable Securities that have
requested to participate in such offering, and the number of shares of
Registrable Securities that may be included in the registration and underwriting
shall be allocated pro rata among such Holders thereof in proportion, as nearly
as practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the Registration Statement.  No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

     If any Holder disapproves of the terms of the underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company, the underwriter
and the Initiating Holders. The Registrable Securities so withdrawn shall also
be withdrawn from registration.

     If the underwriter has not limited the number of Registrable Securities to
be underwritten, the Company may include securities for its own account (or for
the account of other stockholders) in such registration if the underwriter so
agrees and if the number of Registrable Securities would not thereby be limited.

     2.3  Piggyback Registration.
          ----------------------

          (a) Company Registration.  If at any time or from time to time the
              --------------------
Company shall determine to register any of its securities, either for its own
account or for the account of security holders, other than a registration
relating solely to employee benefit plans, a registration on Form S-4 relating
solely to an SEC Rule 145 transaction or a registration pursuant to Section 2.2
or 2.9 hereof, the Company will:

              (i)   promptly (but in any event within 10 days) give to each
Holder written notice thereof; and

              (ii)  include in such registration (and any related qualification
under state securities laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 15 days after receipt of such written notice from the
Company, by any Holder or Holders, except as set forth in Section 2.3(b) below.

     Such Registrable Securities shall only be included to the extent that
inclusion will not diminish the number of securities included by the Company.

                                       5
<PAGE>

          (b) Underwriting.  If the registration of which the Company gives
              ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 2.3(a)(i). In such event the right of any Holder to
registration pursuant to this Section 2.3 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.

     All Holders proposing to distribute their Registrable Securities through
such underwriting shall, together with the Company and the other parties
distributing their securities through such underwriting, enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of this Section 2.3, if the underwriter determines that marketing
factors require a limitation of the number of shares to be underwritten, the
underwriter may limit the number of Registrable Securities to be included in the
registration and underwriting, or may exclude Registrable Securities entirely
from such registration and underwriting subject to the terms of this Section
2.3. The Company shall so advise all holders of the Company's securities that
would otherwise be registered and underwritten pursuant hereto, and the number
of shares of such securities, including Registrable Securities, that may be
included in the registration and underwriting shall be allocated in the
following manner: shares, other than Registrable Securities and other securities
that have contractual rights with respect to registration similar to those
provided for in this Section 2.3, requested to be included in such registration
by stockholders shall be excluded; if a limitation on the number of shares is
still required, securities, other than the Registrable Securities, that have
contractual rights with respect to registration shall be reduced in proportion,
as nearly as practicable, to the amounts of such securities with such
contractual rights held by each such holder at the time of filing the
Registration Statement; and after excluding all such securities, if a limitation
on the number of shares is still required, the number of Registrable Securities
that may be included shall be reduced in proportion, or as nearly as
practicable, to the amounts of Registrable Securities held by each such holder
at the time of filing the Registration Statement. For purposes of any such
underwriter cutback, all Registrable Securities and other securities held by any
holder that is a partnership, limited liability company or corporation shall
also include any Registrable Securities held by the partners, retired partners,
members, stockholders or affiliated entities of such holder, or the estates and
family members of any such partners, retired partners, members and any trusts
for the benefit of any of the foregoing persons, and such holder and other
persons shall be deemed to be a single "selling holder," and any pro rata
reduction with respect to such "selling holder" shall be based upon the
aggregate amount of shares carrying registration rights owned by all entities
and individuals included in such "selling holder", as defined in this sentence.
No securities excluded from the underwriting by reason of the underwriters
marketing limitation shall be included in such registration. Nothing in this
Section 2.3(b) is intended to diminish the number of securities to be included
by the Company in the underwriting.

     If any Holder disapproves of the terms of the underwriting, it may elect to
withdraw therefrom by written notice to the Company and the underwriter. The
Registrable Securities so withdrawn shall also be withdrawn from registration.

          (c) Right to Terminate Registration.  The Company shall have the right
              -------------------------------
to

                                       6
<PAGE>

terminate or withdraw any registration initiated by it under this Section 2.3
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration.

     2.4  Expenses of Registration.  All expenses incurred in connection with
          ------------------------
all registrations effected pursuant to Sections 2.2, 2.3 and 2.9, including
without limitation all registration, filing and qualification fees (including
state securities law fees and expenses), printing expenses, escrow fees, fees
and disbursements of counsel for the Company and expenses of any special audits
incidental to or required by such registration shall be borne by the Company;
provided, however, that the Company shall not be required to pay stock transfer
taxes or underwriters' discounts or selling commissions relating to Registrable
Securities; provided, further, that the Company shall not be required to pay for
any expenses of any registration pursuant to Section 2.9 after the Company has
effected three (3) registrations pursuant to Section 2.9, in which event the
Holders of Registrable Securities to be registered shall bear all such expenses
pro rata on the basis of Registrable Securities to be registered; and provided,
further that only in connection with any registration effected pursuant to
Section 2.2, the Company shall be obligated to pay the legal expenses of one
legal counsel designated by the Investors participating in the registration in
an amount not to exceed $25,000 per registration.  Notwithstanding anything to
the contrary above, the Company shall not be required to pay for any expenses of
any registration proceeding under Section 2.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to have been registered, in which event the Holders of
Registrable Securities to have been registered shall bear all such expenses pro
rata on the basis of the Registrable Securities to have been registered.
Notwithstanding the preceding sentence, however, if at the time of the
withdrawal, the Holders have learned of a materially adverse change in the
condition, business or prospects of the Company from that known to the Holders
at the time of their request, then the Holders shall not be required to pay any
of said expenses and shall retain their rights pursuant to Section 2.2.

     2.5  Obligations of the Company.  Whenever required under this Section 2 to
          --------------------------
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a) prepare and file with the SEC a Registration Statement with
respect to such Registrable Securities and use its diligent efforts to cause
such Registration Statement to become effective, and keep such Registration
Statement effective for the lesser of 180 days or until the Holder or Holders
have completed the distribution relating thereto provided however that the
Company shall have the right to terminate such Registration Statement, or to
place a stop-transfer order with respect to the shares for which registration
has been requested thereunder, upon notice to the participating Holders to the
extent necessary, in the sole discretion of the Company upon the advice of
counsel, to avoid any requirement that the Company disclose material, nonpublic
information, the disclosure of which would be seriously detrimental to the
Company and its stockholders.

          (b) prepare and file with the SEC such amendments and supplements to
such

                                       7
<PAGE>

Registration Statement and the prospectus used in connection with such
Registration Statement as may be necessary to keep such Registration Statement
effective and to comply with the provisions of the 1933 Act with respect to the
disposition of all securities covered by such registration statement.

          (c) furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

          (d) use its diligent efforts to register or otherwise qualify the
securities covered by such Registration Statement under such other securities
laws of such states and other jurisdictions as shall be reasonably requested by
the Holders or the managing underwriter, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such states
or jurisdictions.

          (e) in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f) notify each Holder of Registrable Securities covered by such
Registration Statement, at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act, of the happening of any event as a
result of which the prospectus included in such Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

          (g) use its diligent efforts to list the Registrable Securities
covered by such Registration Statement with any securities exchange on which the
Common Stock is then listed.

          (h) make available for inspection by each Holder including Registrable
Securities in such registration, any underwriter participating in any
distribution pursuant to such registration, and any attorney, accountant or
other agent retained by such Holder or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, as such
parties may reasonably request, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such Holder,
underwriter, attorney, accountant or agent in connection with such Registration
Statement.

          (i) cooperate with Holders including Registrable Securities in such
registration and the managing underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold, such certificates to be in such denominations and registered in such
names as such Holders or the managing underwriters may request at least two
business days prior to any sale of Registrable Securities.

                                       8
<PAGE>

          (j) permit any Holder, which Holder, in the sole and exclusive
judgment, exercised in good faith, of such Holder, might be deemed to be a
controlling person of the Company, to participate in good faith in the
preparation of such Registration Statement and to require the insertion therein
of material, furnished to the Company in writing, that in the reasonable
judgment of such Holder and its counsel should be included.

          (k) use its best efforts (if the offering is underwritten) to furnish,
at the request of any Holder, on the date that Restricted Securities are
delivered to the underwriters for sale pursuant to such registration:  (i) an
opinion dated such date of counsel representing the Company for the purposes of
such registration, addressed to the underwriters and to such Holder, stating
that such Registration Statement has become effective under the 1933 Act and
that (A) to the best knowledge of such counsel, no stop order suspending the
effectiveness thereof has been issued and no proceedings for that purpose have
been instituted or are pending or contemplated under the 1933 Act, (B) the
Registration Statement, the related prospectus, and each amendment or supplement
thereof, comply as to form in all material respects with the requirements of the
1933 Act and the applicable rules and regulations of the Securities and Exchange
Commission thereunder (except that such counsel need express no opinion as to
financial statements, the notes thereto, and the financial schedules and other
financial and statistical data contained therein) and (C) to such other effects
as may reasonably be requested by counsel for the underwriters or by such Holder
or its counsel and (ii) a letter dated such date from the independent public
accountants retained by the Company, addressed to the underwriters, stating that
they are independent public accountants within the meaning of the 1933 Act and
that, in the opinion of such accountants, the financial statements of the
Company included in the registration statement or the prospectus, or any
amendment or supplement thereof, comply as to form in all material respects with
the applicable accounting requirements of the 1933 Act, and such letter shall
additionally cover such other financial matters (including information as to the
period ending no more than five business days prior to the date of such letter)
with respect to the registration in respect of which such letter is being given
as such underwriters or Holder may reasonably request.

     2.6  Indemnification.
          ---------------

          (a) The Company will, and does hereby undertake to, indemnify and hold
harmless each Holder of Registrable Securities, each of such Holder's officers,
directors, managers, partners, members and agents, and each person controlling
such Holder, with respect to any registration, qualification or compliance
effected pursuant to this Section 2, and each underwriter, if any, and each
person who controls any underwriter, of the Registrable Securities held by or
issuable to such Holder, against all claims, losses, damages and liabilities (or
actions in respect thereto) to which they may become subject under the 1933 Act,
the Securities Exchange Act of 1934, as amended (the "1934 Act"), or other
federal or state law arising out of or based on (i) any untrue statement (or
alleged untrue statement) of a material fact contained in any prospectus,
offering circular or other similar document (including any related Registration
Statement, notification, or the like) incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances in which
they were made, (ii) any violation or alleged violation by the Company

                                       9
<PAGE>

of any federal, state or common law rule or regulation applicable to the Company
in connection with any such registration, qualification or compliance, or (iii)
any failure to register or qualify Registrable Securities in any state where the
Company or its agents have affirmatively undertaken or agreed in writing that
the Company (the undertaking of any underwriter chosen by the Company being
attributed to the Company) will undertake such registration or qualification on
behalf of the Holders of such Registrable Securities (provided that in such
instance the Company shall not be so liable if it has undertaken its best
efforts to so register or qualify such Registrable Securities) and will
reimburse, as incurred, each such Holder, each such underwriter and each such
director, manager, officer, partner, member, agent and controlling person, for
any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action;
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission made in conformity with written information
furnished to the Company by an instrument duly executed by such Holder or
underwriter and stated to be specifically for use therein.

          (b) Each Holder will, and if Registrable Securities held by or
issuable to such Holder are included in such registration, qualification or
compliance pursuant to this Section 2, does hereby undertake to indemnify and
hold harmless the Company, each of its directors and officers, and each person
controlling the Company, each underwriter, if any, and each person who controls
any underwriter, of the Company's securities covered by such a Registration
Statement, and each other Holder, each of such other Holder's officers,
directors, managers, partners, members and agents and each person controlling
such other Holder, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on (i) any failure of such
Holder or its agents or representatives to comply with the prospectus delivery
requirements of the 1933 Act or any other applicable securities or Blue Sky law,
or (ii) any untrue statement (or alleged untrue statement) of a material fact
contained in any such Registration Statement, prospectus, offering circular or
other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances in which they were made,
and will reimburse, as incurred, the Company, each such underwriter, each such
other Holder, and each such director, officer, manager, partner, member and
controlling person of the foregoing, for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) was made in such Registration Statement,
prospectus, offering circular or other document, in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein;
provided, however, that the liability of each Holder hereunder (unless such
Holder's liability hereunder is based upon such Holder's willful misconduct as
determined by the nonappealable final decision of a court) shall be limited to
the proportion of any such claim, loss, damage or liability that is equal to the
proportion that the public offering price of the shares sold by such Holder
under such Registration Statement bears to the total public offering price of
all securities sold thereunder, but in any event not to exceed the net proceeds
received by such Holder from the sale of securities under such Registration
Statement. It is understood and agreed that the indemnification obligations of
each Holder pursuant to any underwriting

                                       10
<PAGE>

agreement entered into in connection with any Registration Statement shall be
limited to the obligations contained in this subsection 2.6(b).

          (c) Each party entitled to indemnification under this Section 2.6 (the
"Indemnified Party") shall give notice to the party required to provide such
indemnification (the "Indemnifying Party") of any claim as to which
indemnification may be sought promptly after such Indemnified Party has actual
knowledge thereof, and shall permit the Indemnifying Party to assume the defense
of any such claim or any litigation resulting therefrom; provided that counsel
for the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be subject to approval by the Indemnified Party (whose
approval shall not be unreasonably withheld) and the Indemnified Party may
participate in such defense at the Indemnifying Party's expense if
representation of such Indemnified Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by such counsel in such proceeding; and provided further that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Section 2, except
to the extent that such failure to give notice shall materially adversely affect
the Indemnifying Party in the defense of any such claim or any such litigation.
An Indemnifying Party, in the defense of any such claim or litigation, may,
without the consent of each Indemnified Party, consent to entry of any judgment
or enter into any settlement that includes as an unconditional term thereof the
giving by the claimant or plaintiff therein, to such Indemnified Party, of a
release from all liability with respect to such claim or litigation.

          (d) In order to provide for just and equitable contribution to joint
liability under the 1933 Act in any case in which either (i) any Holder
exercising rights under this Agreement, or any controlling person of any such
Holder, makes a claim for indemnification pursuant to this Section 2.6 but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 2.6 provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 2.6; then, and in each such case,
the Company and such Holder will contribute to the aggregate claims, losses,
damages or liabilities to which they may be subject (after contribution from
others) in such proportion so that such Holder is responsible for the portion
represented by the percentage that the public offering price of the securities
offered by such Holder pursuant to the Registration Statement bears to the
public offering price of all securities offered by such Registration Statement,
and the Company will be responsible for the remaining portion (without prejudice
as to the Company's right to contributions from any other responsible parties);
provided, however, that, in any case, (A) no such Holder will be required to
contribute any amount in excess of the public offering price of all securities
offered by it pursuant to such Registration Statement, after deduction of
underwriting discounts and commissions (unless such Holder's liability hereunder
is based upon such Holder's willful misconduct as determined by the
nonappealable final decision of a court); and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11 (f) of the 1933
Act) will be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation.

                                       11
<PAGE>

          (e) The indemnities provided in this Section 2.6 shall survive the
transfer of any Registrable Securities by such Holder.

     2.7  Information by Holder.  The Holder or Holders of Registrable
          ---------------------
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may reasonably request in writing and as
shall be required in connection with any registration, qualification or
compliance referred to in this Section 2.

     2.8  Transfer of Rights.  The rights contained in Section 2 hereof may be
          ------------------
assigned or otherwise conveyed to transferees or assignees of Registrable
Securities, who shall be considered a "Holder" for purposes hereof, provided
that such transfer is effected in compliance with Section 1.2 hereof and such
transfer is a "Permitted Transfer" as defined herein.

          (b) For purposes of this Agreement, a "Permitted Transfer" shall mean:
(i) a transaction not involving a change in beneficial ownership; (ii)
transactions involving distribution without consideration by a stockholder that
is a partnership, limited liability company or corporation to any of its
partners, members or stockholders (as the case may be), retired partners,
members or stockholders, or to the estate of any of its partners, members or
stockholders; (iii) transaction involving distribution without consideration by
a stockholder that is a corporation to any of its stockholders; (iv) transfers
by any stockholder who is an individual to a trust for the benefit of such
stockholder or his family; (v) a transfer in which the transferee acquires at
least 50,000 shares of Registrable Securities, subject to adjustments for
combinations, consolidations, recapitalizations, stock splits, stock dividends
and the like; or (vi) transfers by gift, will or intestate succession to the
spouse, lineal descendants or ancestors of any stockholder or spouse of a
stockholder.

     2.9  Form S-3.  The Company shall use its diligent efforts to qualify for
          --------
registration on Form S-3 and to that end the Company shall register the Common
Stock under the 1934 Act within 12 months following the effective date of the
first registration of any securities of the Company on Form S-1.  After the
Company has qualified for the use of Form S-3, the Holders of Registrable
Securities shall have the right to request registrations on Form S-3 thereafter
under this Section 2.9. The Company shall give notice to all Holders of
Registrable Securities of the receipt of a request for registration pursuant to
this Section 2.9 and shall provide a reasonable opportunity for other Holders to
participate in the registration. Subject to the foregoing, the Company will use
its best efforts to effect as soon as practicable the registration of all shares
of Registrable Securities on Form S-3 to the extent requested by the Holder or
Holders thereof for purposes of disposition; provided, however, that the Company
shall not be obligated to effect any such registration (A) if the Holders,
together with the holders of any other securities of the Company entitled to
inclusion in such registration, propose to sell Registrable Securities and such
other securities (if any) at an aggregate price to the public of less than
$2,500,000 or (B) at any time when the Company has effected one (1) registration
pursuant to this Section 2.9 in the previous six (6) months.  Notwithstanding
the foregoing, nothing herein shall restrict, prohibit or limit in any way a
Holder's ability to exercise its registration rights under Sections 2.2 or 2.3
hereof.  The Company shall have no obligation to take any action to effect any
registration pursuant to this Section 2.9 for any of the reasons set forth in
Section 2.2(a)(ii)(A) or (C), (which

                                       12
<PAGE>

shall be deemed to apply to the obligations under this Section 2.9 with equal
force). In addition, any registration pursuant to this Section 2.9 shall be
subject to the provisions of Section 2.2(b), which shall be deemed to apply to
the obligations under this Section 2.9 with equal force, except that any
reference therein to Section 2.2 or a subsection thereof shall, for these
purposes only, be deemed to be a reference to this Section 2.9.

     2.10  Delay of Registration.  No Holder shall have any right to obtain or
           ---------------------
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 2.

     2.11  Limitations on Subsequent Registration Rights.  From and after the
           ---------------------------------------------
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of at least 75% of the Registrable Securities then outstanding
and not registered, enter into any agreement with any holder or prospective
holder of any securities of the Company that would allow such holder or
prospective holder to (i) require the Company to effect a registration or (ii)
include any securities in any registration filed under Section 2.2, 2.3 or 2.9
hereof, unless, under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of such securities will not diminish the amount of
Registrable Securities that are included in such registration.

     2.12  Rule 144 Reporting.  With a view to making available to the Holders
           ------------------
the benefits of certain rules and regulations of the SEC that may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its diligent efforts to:

           (a) Make and keep current public information available, within the
meaning of SEC Rule 144 or any similar or analogous rule promulgated under the
1933 Act, at all times after it has become subject to the reporting requirements
of the 1934 Act;

           (b) File with the SEC, in a timely manner, all reports and other
documents required of the Company under the 1933 Act and 1934 Act (after it has
become subject to such reporting requirements);

           (c) So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time
commencing 90 days after the effective date of the first registration filed by
the Company for an offering of its securities to the general public), the 1933
Act and the 1934 Act (at any time after it has become subject to such reporting
requirements); a copy of the most recent annual or quarterly report of the
Company; and such other reports and documents as a Holder may reasonably request
in availing itself of any rule or regulation of the SEC allowing it to sell any
such securities without registration.

     2.13  "Market Stand-Off" Agreement.  Each Holder that is a "One Percent
           ----------------------------
Stockholder," as defined below, hereby agrees that during a period, not to
exceed 180 days, following the effective date of the initial, effective
registration statement of the Company filed under the 1933 Act, it shall not, to
the extent requested by the Company and any underwriter, sell, pledge, transfer,
make any short sale of, loan, grant any option for the purchase of, or

                                       13
<PAGE>

otherwise transfer or dispose of (other than to donees who agree to be similarly
bound or, subject to underwriter approval, for Holders that are entities, to
such Holders' members or partners (as applicable) who agree to be similarly
bound, or other than any sales under such registration statement) any Common
Stock held by it at any time during such period except Common Stock included in
such registration; provided, however, that all other "One Percent Stockholders"
with registration rights (whether or not pursuant to this Agreement) and all
officers and directors of the Company enter into similar agreements and such
agreement shall be applicable only to the first such registration statement of
the Company that covers Common Stock (or other securities) to be sold on its
behalf to the public in an underwritten offering.

     For purposes of this Section 2.13, the term "One Percent Stockholder" shall
mean a stockholder of the Company who holds at least one percent of the
outstanding Common Stock of the Company (assuming conversion of all outstanding
Series E Stock of the Company and all other convertible securities of the
Company).

     In order to enforce the foregoing covenant, the Company may impose stop
transfer instructions with respect to the Registrable Securities of each Holder
(and the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

     2.14  Amendment of Registration Rights.    Any provision of this Section 2
           ---------------------------------
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least 66 2/3% of the
Registrable Securities then outstanding and not registered.  Any amendment or
wavier effected in accordance with this Section shall be binding upon each
Holder, each future Holder of Registrable Securities and the Company.

     2.15  Inclusion of Stock Held by Common Holders.  In connection with any
           -----------------------------------------
registration effected pursuant to Section 2.3 hereof, the Common Holders shall
be entitled to include in such registration (on the same terms and conditions as
Holders selling their Registrable Securities in such registration) shares of
Common Stock held by such Common Holders; provided that any limitation by the
underwriter on the number of shares to be underwritten in connection with such
registration shall first be applied to the shares so included by such Common
Holders, as provided in Section 2.3(b), and provided further that each such
Common Holder's right to include shares of Common Stock in a registration
pursuant to this Section 2.15 is contingent upon such Common Holder's execution
of an indemnification and hold harmless agreement substantially in accordance
with Section 2.6(b) and an agreement to be bound by all other applicable
restrictions contained in this Section 2.

     2.16  Termination of Rights.  The rights of any particular Holder to cause
           ---------------------
the Company to register securities under Section 2.2, 2.3 or 2.9 hereof shall
terminate as to any Holder on the earlier of (a) the date (and during such
period) that such Holder is able to dispose of all of its Registrable Securities
in any 90-day period pursuant to SEC Rule 144 (or any similar or analogous rule
promulgated under the 1933 Act), or (b) the third anniversary of the closing of
the Company's initial public offering of stock.


                                  Section 3.

                            RIGHT OF FIRST REFUSAL;
                            -----------------------
                               RIGHT OF CO-SALE
                               ----------------

     3.1  Certain Definitions.  As used in this Section 3:
          -------------------

          (a) The term "New Securities" shall mean any capital stock of the
Company, whether now authorized or not, and rights, options or warrants to
purchase capital stock, and securities of any type whatsoever that are, or may
become, convertible into capital stock; provided that the term "New Securities"
does not include: (i) the Series E Stock; (ii) securities issuable upon
conversion of or with respect to Series E Stock or up to 6,402,102 shares (which
number shall be appropriately adjusted for any stock splits, stock dividends,
recapitalizations or similar events) issuable upon conversion of any other
preferred stock or equity or debt security of the Company issued on or prior to
the date hereof; (iii) up to [1,165,278] shares of Common Stock (which number
shall be appropriately adjusted for any stock splits, stock dividends,
recapitalizations or similar events), and options, warrants or rights
convertible into such Common Stock, issued or issuable to employees, consultants
or directors of the Company pursuant to any incentive agreement or arrangement
approved by the Board of Directors of the Company; (iv) up to 112,500 shares
(which number shall be appropriately adjusted for any stock splits, stock
dividends, recapitalizations or similar events) of capital stock or securities
exercisable for or convertible into such capital stock issued in connection with
any equipment leases or borrowings, direct or indirect, from financial or other
institutions regularly engaged in such business; (v) up to 349,999 shares (which
number shall be appropriately adjusted for any stock splits, stock dividends,
recapitalizations or similar events) issuable upon exercise of warrants to
purchase the Company's preferred stock; or (vi) securities issued pursuant to
any stock dividend, stock split, combination or other reclassification by the
Company of any of its capital stock.

          (b) The term "Pro Rata Share" means the ratio (A) the numerator of
which is the number of shares of Common Stock held by such Holder, or issuable
to such Holder upon the conversion or exercise of all securities convertible
into or exercisable for Common Stock of the Company held by such Holder, on the
date of the written notice pursuant to Section 3.2 hereof, and (B) the
denominator of which is (i) with respect to the right of first refusal set forth
in Section 3.2, the number of shares of Common Stock outstanding, assuming for
this purpose conversion or exercise of all securities convertible into or
exercisable for Common Stock of the Company or (ii) with respect to the right of
co-sale set forth in Section 3.3, the number of shares of Common Stock held by
or issuable to all Holders who intend to exercise co-sale rights with respect to
such sale and by the Common Holder desiring to sell or transfer Common Stock
pursuant to Section 3.3.

     3.2  Right of First Refusal.  The Company hereby grants to each Holder,
          ----------------------
subject to the terms and conditions specified in this Section 3.2, the right of
first refusal to purchase, on the terms and conditions set forth in the
Company's notice pursuant to this Section 3.2, up to its Pro Rata Share of all
New Securities that the Company may, from time to time, propose to sell and
issue.  In the event the Company proposes to undertake an issuance of New
Securities, it shall give each Holder written notice (the "Election Notice") of
its intention, describing the type of

                                       15
<PAGE>

New Securities, the price and the general terms upon which the Company proposes
to issue the same. Each Holder shall have 15 days from the date of any such
notice to exercise its right of first refusal under this Section 3.2 for the
price and upon the general terms specified in the notice by giving written
notice to the Company and stating therein the quantity of New Securities to be
purchased. Each Holder shall also have the option, exercisable by so specifying
in the Election Notice, to purchase such Holder's pro rata portion of any
remaining New Securities not purchased by other Holders, in which case the
Holders exercising such further option shall be deemed to have elected to
purchase such Holder's pro rata portion of such remaining New Securities, up to
an aggregate maximum number of New Securities which such Holder shall have
specified in the Election Notice. The Company shall have 90 days after the 15-
day period described in this Section 3.2 to sell all such New Securities
respecting which the Holders' rights of first refusal hereunder were not
exercised, at a price and upon terms no more favorable in any material respect
to the purchasers thereof than specified in the Company's notice. In the event
the Company has not sold all such New Securities within such 90-day period, the
Company shall not thereafter issue or sell any New Securities without first
notifying the Investors in the manner provided herein.

     3.3  Right of Co-Sale.   If at any time a Common Holder or Other Holder
          ----------------
desires (or is required) to sell or transfer in any manner any shares of capital
stock of the Company or securities convertible or exercisable into capital stock
of the Company pursuant to the terms of a bona fide offer received from a third
party (the "Buyer"), each Holder shall have the right to require, as a condition
to such sale or transfer, that the Buyer purchase from such Holder at the same
price per share and on the same terms and conditions as involved in such sale or
disposition by such Common Holder or Other Holder that percentage of the number
of shares of capital stock proposed to be acquired by the Buyer from such Common
Holder or Other Holder (the "Offered Shares") equal to such Holder's Pro Rata
Share.  Each Holder shall act upon the Buyer's offer to buy within twenty (20)
days after receipt of the written notice delivered by such Common Holder or
Other Holder to the Company and each Holder that fully describes the offer.  In
the event that one or more Holders shall elect to participate in such sale or
transfer, each such Holder shall communicate in writing such election to such
Common Holder or Other Holder.

     3.4  Expiration of Right.  The rights of first refusal and rights of co-
          -------------------
sale granted under this Section 3 shall not apply to, and shall expire upon, the
closing of a Qualified Public Offering (as defined in Section 4.4 below).

     3.5  No Waiver.  The exercise or non-exercise by a Holder of its or his
          ---------
rights under this Section 3 shall not adversely affect its right to exercise
such rights in connection with future transfers or sales.


                                  Section 4.

                               COMPANY COVENANTS

and the like, the Company will furnish each Holder, subject to Section 4.1(b)

statements may not contain notes and will be subject to year-end adjustment, and
certified by the principal financial or accounting officer of the Company. Such
quarterly report shall include a narrative, summary description of the Company's
operations for such quarter, indicating whether the Company is materially in
compliance with this Agreement and other material agreements and discussing any
material variances from the Company's operating plan;

              (iii) Within 30 days prior to the end of each fiscal year, an
operating budget, prepared on a quarterly basis, for the succeeding fiscal year;

respecting the business, properties or the condition or operations, financial or
other, of the Company or any subsidiary as any Holder may from time to time
reasonably request.

          (b) The Company shall not be obligated pursuant to this Section 4.1 to
provide financial information to any person whom the Company reasonably believes
is a competitor of the Company.

          (c) The rights granted pursuant to this Section 4.1 may be assigned or
otherwise conveyed by any Investor or by any subsequent transferee of any such
rights, provided that the Company is given prior written notice of any such
proposed assignment or conveyance;

                                       17
<PAGE>

and provided further that the Company may refuse to permit such assignment or
conveyance if the proposed transferee is reasonably believed by the Company to
be a competitor of the Company.

     4.2  Inspection.  The Company shall permit each Investor and each
          ----------
transferee in a Permitted Transfer (as defined in Section 2.8(b) hereof)
(provided such transfer is effected in compliance with Section 1.2 hereof), its
attorney or its other representative to visit and inspect the Company's
properties, to examine the Company's books of account and other records, to make
copies or extracts therefrom and to discuss the Company's affairs, finances and
accounts with its officers, management, employees and independent auditors all
at such reasonable times and as often as such Investor or transferee may
reasonably request; provided, however, that the Company shall not be obligated
pursuant to this Section 4.2 to provide trade secrets or confidential
information or to provide information to any person whom the Company reasonably
believes is a competitor of the Company; provided, further, that such Investor
shall bear any costs or expenses of such investigations or inquiries.

     4.3  Additional Affirmative Covenants.  Without limiting any other covenant
          --------------------------------
or provision hereof, the Company covenants and agrees that, so long as at least
50,000 shares of Series E Stock remain outstanding, it will, and will cause each
subsidiary (to the extent applicable thereto) of the Company, if and when such
subsidiary exists, to:

          (a) Payment of Taxes.  Pay, and cause each subsidiary to pay, and
              ----------------

          -----------------------
shall expire and be of no further force or effect upon the effectiveness of a
Qualified Public Offering (as defined below).  A "Qualified Public Offering"
shall mean an effective registration statement for the sale of the Company's
shares of Common Stock in a firm commitment underwritten public offering
registered under the 1933 Act generating proceeds (before deducting
underwriters' commissions and discounts) to the Company of $40,000,000 or more
and the price per share to the public is not less than 150% of the Series E
purchase price per share, subject to adjustment for stock splits, stock
dividends and the like (other that a registration relating solely to employee
benefit plans or to a transaction under Rule 145 under the 1933 Act or any
successor rule thereto).  After such time, the Investors shall be entitled to
receive such annual and quarterly reports as the Company shall distribute to its
stockholders generally.


                                   Section 5.

                               OBSERVATION RIGHTS
                               ------------------

     Until such time as the Company shall have consummated a Qualified Public
Offering (as defined in Section 4.4 hereof), the Investors shall have the right
to appoint one (1) observer to the Board of Directors of the Company, as
designated by Canaan Partners, who initially shall be Dr. Seth Rudnick.  Such
observer will be allowed to participate in all discussions of the Board of
Directors but will not be a voting member of the Board of Directors.  The
Company shall reimburse the observer appointed by the Investors for reasonable
expenses incurred to attend meetings of the Board of Directors.


                                   Section 6.

                              PROHIBITED TRANSFERS
                              --------------------

     Until the closing of a Qualified Public Offering or the closing of a
transaction that results in liquidation rights for the Series E Preferred under
the Company's Certificate of Incorporation, no Common Holder may sell, pledge or
otherwise transfer more than 10% of such Common

                                       20
<PAGE>

Holder's shares of the Company held at the Closing of the Series E Agreement
without the written consent of 66 2/3% of the shares (on an as-converted basis)
held by the Investors. Notwithstanding the previous provision, transfers to the
following persons (each a "Permitted Transferee") do not require consent of the
Investors: (i) a member of the Common Holder's immediate family (defined to
include his parents, children and lineal descent (whether by birth or adoption),
spouse, siblings and the children of siblings (whether by birth or adoptions))
or (ii) a trust or family limited partnership established by the Common Holder
for the benefit of himself or his immediate family (each such Transfer a
"Permitted Transfer"). No Permitted Transfer shall be effective unless and until
the Permitted Transferee shall have executed such documentation, in form and
substance satisfactory to the Company, evidencing agreement by the Permitted
Transferee to be bound by the provisions of this Agreement.


                                   Section 7.

                                 MISCELLANEOUS
                                 -------------

     7.1  Governing Law.  This Agreement shall be governed by, and construed and
          -------------
interpreted in accordance with the laws of the State of Delaware as applied to
agreements among Delaware residents made and to be performed entirely within the
State of Delaware.

     7.2  Successors and Assigns.  Except as otherwise expressly provided
          ----------------------
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.

     7.3  Entire Agreement.  This Agreement constitutes the full and entire
          ----------------
understanding and agreement among the parties with regard to the subjects
hereof. Nothing in this Agreement, express or implied, is intended to confer
upon any party, other than the parties hereto and their successors and assigns,
any rights, remedies, obligations or liabilities under or by reason of this
Agreement, except as expressly provided herein.

     7.4  Severability.  Any invalidity, illegality or limitation of the
          ------------
enforceability with respect to any Holder of any one or more of the provisions
of this Agreement, or any part thereof, whether arising by reason of the law of
any such person's domicile or otherwise, shall in no way affect or impair the
validity, legality or enforceability of this Agreement with respect to any other
Holder. In case any provision of this Agreement shall be invalid, illegal or
unenforceable, it shall to the extent practicable, be modified so as to make it
valid, legal and enforceable and to retain as nearly as practicable the intent
of the parties, and the validity, legality, and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

     7.5  Amendment and Waiver.  Except as otherwise expressly provided herein,
          --------------------
any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance, either
retroactively or prospectively and either for a specified period of time or
indefinitely) with the written consent of the Company and the Investors, or
their transferees holding at least 66 2/3% of the shares of Series E Stock,
voting together as a single group (treated as if converted at the conversion
rate then in effect and

                                       21
<PAGE>

including, for such purposes shares of Common Stock into which any shares of
Series E Stock shall have been converted that are held by a Holder); provided,
however, that no such amendment or waiver shall reduce the aforesaid percentage
of Series E Stock and Common Stock issued upon conversion thereof, the holders
of which are required to consent to any waiver or supplemental agreement,
without the consent of the holders of all of such Series E Stock and Common
Stock; provided, further, that any amendment to Section 2.15 (or to Section 2.3
that would affect the rights under Section 2.15) shall also require the consent
of the holders of at least a majority of the shares of Common Stock issued to,
or issuable upon exercise of options held by, the Common Holders; and provided
further, that no amendment to Section 5 hereof shall be effective without the
written consent of the Company and the Investors, or their transferees, holding
at least 75% of the shares of Series E Stock, voting together as a single group
(treated as if converted at the conversion rate then in effect and including,
for such purposes shares of Common Stock into which any shares of Series E Stock
shall have been converted that are held by a Holder). Any amendment or waiver
effected in accordance with this Section 7.5 shall be binding upon each Common
Holder, each Investor and each transferee of the Registrable Securities. Upon
the effectuation of each such amendment or waiver, the Company shall promptly
give written notice thereof to the Investors and Common Holders who have not
previously consented thereto in writing. Notwithstanding anything to the
contrary in this Section 7.5, the Company shall be entitled to include
additional purchasers of its Series E Stock pursuant to the Series E Agreement
as parties to this Agreement, and to treat such purchasers as "Investors" and
"Holders" hereunder, by amending Exhibit A attached hereto and providing such
                                 ---------
Exhibit A, as amended, to the other parties to this Agreement.
- ---------

     7.6  Delays or Omissions.  No delay or omission to exercise any right,
          -------------------
power or remedy accruing to the Company, the Investors, or any transferees upon
any breach, default or noncompliance of the Investors or any transferee or the
Company under this Agreement, shall impair any such right, power or remedy, nor
shall it be construed to be a waiver of any such breach, default or
noncompliance, or any acquiescence therein, or of any similar breach, default or
noncompliance thereafter occurring. It is further agreed that any waiver,
permit, consent or approval of any kind or character on the part of the Company
or the Investors of any breach, default or noncompliance under this Agreement or
any waiver on the Company's or the Investors' part of any provisions or
conditions of this Agreement must be in writing and shall be effective only to
the extent specifically set forth in such writing and that all remedies, either
under this Agreement, by law, or otherwise afforded to the Company and the
Investors, shall be cumulative and not alternative.
