                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements appearing elsewhere in this
Prospectus. Except as otherwise noted, all information in this Prospectus
assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY
 
  Ergo Science Corporation is developing novel treatments for metabolic
disorders, including Type II diabetes and obesity, and for cancer. The
Company's technology uses orally administered neurotransmitter modulating drugs
to address abnormalities of the neuroendocrine system. The Company believes
that its approach may provide the platform for a new class of treatments for a
variety of glucose and lipid metabolic disorders and cancer. The Company's lead
drug candidate, ERGOSET(TM), is a low-dose, fast-release, oral tablet
formulation of bromocriptine, a dopamine agonist previously approved by the
U.S. Food and Drug Administration to treat Parkinson's disease and other
conditions. The Company recently completed two Phase III clinical trials of
ERGOSET as adjunctive therapy with sulfonylurea agents for the treatment of
Type II diabetes. A preliminary analysis of the two completed Phase III
clinical trials indicated that ERGOSET improved control of glucose,
triglycerides, free fatty acids, and cholesterol in Type II diabetics. The
Company anticipates completing a third Phase III clinical trial of ERGOSET as
monotherapy for Type II diabetes by the end of 1996. The Company plans to
submit a New Drug Application to FDA for ERGOSET to treat Type II diabetes in
1997. Ergo has also conducted clinical trials of ERGOSET for the treatment of
obesity and intends to conduct additional obesity clinical trials of ERGOSET by
itself and in combination with another product candidate. Ergo currently
retains all marketing rights to its drug candidates.
 
  Ergo's technology is the result of over 30 years of research by the Company's
founding scientists into the regulation of glucose and lipid metabolism through
changes in daily patterns of neuroendocrine activity. Ergo's scientists have
shown that when vertebrate animals are in a fat, insulin resistant condition,
they exhibit a daily neuroendocrine pattern that is distinctly different from
their daily neuroendocrine pattern while in a lean, insulin sensitive
condition. Ergo's technology is based on observations that, just as animals
display changes in daily patterns of neuroendocrine activity to become
seasonally fat and insulin resistant to survive adverse environmental
conditions, humans display changes in daily neuroendocrine patterns as they
develop Type II diabetes. The aging process, as well as changes in the
environment of humans such as diet, sedentary lifestyles and artificial
lighting, may be causing changes in daily neuroendocrine patterns in humans.
Moreover, the Company has demonstrated that the timed administration of drugs
can alter daily neuroendocrine patterns and produce desired metabolic changes
in animals. The Company believes that its research and clinical trial data
indicate that the timed administration of neurotransmitter modulating drugs
alters these daily neuroendocrine patterns in humans, producing improvements in
glucose and lipid metabolism.
 
  The markets for Type II diabetes and obesity are large and not adequately
addressed by current treatments. Approximately 15 million people will suffer
from Type II diabetes in the United States in 1996, and that number is expected
to increase to approximately 32 million by 2010. Obesity affects approximately
35 million Americans, or approximately 26% of the U.S. adult population.
Obesity is considered a risk factor for Type II diabetes, cardiovascular
disease and other conditions.
 
  Ergo's preclinical studies suggest that temporal changes in neuroendocrine
activity may also play an important role in the body's regulation of immune
function and the body's ability to fight cancer. The Company is currently
enrolling patients in a small Phase II clinical trial of two neurotransmitter
modulating compounds for the treatment of metastatic breast cancer.
Approximately 184,000 women in the United States will be diagnosed with breast
cancer in 1996. The Company is also evaluating the use of phototherapeutic dyes
in photodynamic therapy to treat various tumors.
 
  Ergo's commercialization strategy includes the formation of marketing
alliances with large pharmaceutical companies and the establishment of long-
term manufacturing agreements for its product supply. Geneva Pharmaceuticals,
Inc., a subsidiary of Ciba-Geigy Corporation, has agreed to supply the
Company's United States requirements for ERGOSET.
 
                              RECENT DEVELOPMENTS
 
 Summary of Phase III Clinical Trial Results
 
  Ergo recently announced the preliminary analysis of its two completed Phase
III clinical trials of ERGOSET as adjunctive therapy for Type II diabetes.
These double-blinded, placebo-controlled clinical trials investigated the
safety and efficacy of ERGOSET in the treatment of approximately 500 Type II
diabetics using sulfonylurea therapy at 17 trial sites
 
                                       3

across the United States. The primary endpoint of these Phase III clinical
trials was to achieve a clinically and statistically significant reduction in
blood levels of glycated hemoglobin A1c, which is considered a reliable
indicator of glycemic control in diabetics.
 
  The preliminary analysis indicated that ERGOSET improved control of glucose,
triglycerides, free fatty acids, and cholesterol in Type II diabetics. This
preliminary analysis also showed that ERGOSET was generally well-tolerated. On
an intent-to-treat basis, the two completed trials indicated that ERGOSET
improved glycemic control as measured by a reduction in glycated hemoglobin Alc
compared with placebo of 0.5% (p less than 0.0001) in one study and 0.6% (p less
than 0.0007) in the other study. Serum glucose, triglycerides and free fatty
acids were measured throughout the day, and ERGOSET resulted in consistent
reductions compared with placebo in each parameter. Average reductions in serum
glucose compared with placebo were 21 mg/dl (p less than 0.005) and 23 mg/dl (p
less than 0.001) in the two studies. Average reductions in serum triglycerides
compared with placebo were 44 mg/dl (p less than 0.05) and 55 mg/dl (p less than
0.003) in the two studies. The average reduction in free fatty acids compared
with placebo was 149 u eq/L (p less than 0.03) in the one study for which this
parameter is available. In addition, fasting cholesterol levels compared with
placebo were reduced by 5.7 mg/dl (p less than 0.09) and 8.0 mg/dl (p less than
0.04).
 
  A pre-established responder criterion was designed to identify clinically
significant responders to ERGOSET shortly after the initiation of treatment.
Responders were defined as those individuals on ERGOSET who had at least a 0.3%
decrease in glycated hemoglobin Alc from baseline after eight weeks of
treatment. In the responder group, which represented approximately 60% of the
subjects, ERGOSET resulted in decreases of glycated hemoglobin A1c of 1.0% (p
less than 0.0001) and 1.1% (p less than 0.0001) compared with placebo and
decreases in glycated hemoglobin Alc of 0.6% (p less than 0.0001) and 0.8% (p
less than 0.0001) compared with baseline. In the responder group, average
reductions in serum glucose levels were 39 mg/dl (p less than 0.0001) and 37
mg/dl (p less than 0.0001) compared with placebo, and average reductions were
24 mg/dl (p less than 0.06) and 25 mg/dl (p less than 0.01) compared with
baseline. See "Business--ERGOSET for Type II Diabetes--Phase III Clinical Trial
Results."
 
 Obesity Data in the Leptin-Deficient Ob/Ob Mouse
     
  Researchers at Ergo have also used neurotransmitter modulating drugs to
achieve significant reductions in body fat in the leptin-deficient ob/ob mouse,
a genetically insulin resistant and fat animal model. In a study presented at
the 1996 annual meeting of the American Diabetes Association, Ergo's scientists
reported that the administration of two neurotransmitter modulating drugs
produced a significant (approximately 30%) reduction in food intake and a
reduction in body fat of 22% to 32% with no significant decrease in lean
body (muscle) mass compared with control animals. The study also showed a 57%
reduction in blood glucose levels and a 50% reduction in blood insulin levels,
which reflect improved glycemic control. Ergo believes that the selective
reduction in body fat and preservation of lean body mass has significant
implications for the treatment of obesity because improvement in the lean-to-
fat ratio may reduce the cardiovascular risk associated with chronic obesity.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, prospective
investors should consider the following factors in evaluating the Company and
its business before purchasing any of the Common Stock offered hereby.
 
UNCERTAINTIES RELATED TO PHASE III CLINICAL TRIAL RESULTS OF ERGOSET
 
  The Company recently announced its statistical analyses of two Phase III
clinical trials of ERGOSET as adjunctive therapy in obese patients suffering
from Type II diabetes, and it expects to complete the statistical analysis of
a Phase III clinical trial of ERGOSET as monotherapy in obese Type II
diabetics by the end of 1996. The Company intends to file an NDA with FDA for
ERGOSET to treat Type II diabetes in 1997. In order for a drug such as ERGOSET
to be approved for commercial sale, FDA and other authorities require that the
safety and efficacy of the drug be established by at least two adequate and
well-controlled clinical trials. The Company has limited experience in filing
and pursuing applications necessary to gain regulatory approvals. Data
obtained from preclinical and clinical activities are susceptible to varying
interpretations that could delay, limit or prevent FDA regulatory approval.
There can be no assurance that FDA and other regulatory authorities will agree
with the Company's assessment of the results. If FDA or its advisory panel of
experts disagrees with the Company's analysis of the results of the Phase III
clinical trials or believes that the results do not establish that ERGOSET is
safe and effective in the treatment of Type II diabetes, the Company will not
receive the approval necessary to market ERGOSET, which would have a material
adverse effect on the Company. In that case, the Company may have to conduct
additional Phase III clinical trials in an effort to demonstrate the safety
and efficacy of ERGOSET, which also may not be acceptable to FDA. Without
acceptable results and regulatory approval, the Company would not be able to
commercialize ERGOSET, which would have a material adverse effect on the
Company. See "Business--ERGOSET for Type II Diabetes--Phase III Clinical Trial
Results."
 
  If the results of the Phase III clinical trial of ERGOSET as monotherapy for
Type II diabetes are not satisfactory, the Company will not be able to submit
an NDA to FDA for ERGOSET as monotherapy. In that case, the Company may have
to conduct additional Phase III clinical trials in an effort to demonstrate
the safety and efficacy of ERGOSET as monotherapy or may have to submit an NDA
to FDA for ERGOSET as adjunctive therapy only. There can be no assurance that
the results of any of the Company's Phase III clinical trials will be
satisfactory, that ERGOSET will obtain regulatory approval for
commercialization, or that any regulatory approval obtained will not contain
material limitations on the indicated uses for which ERGOSET may be marketed.
See "Business--Government Regulation."
 
GOVERNMENT REGULATION; NO ASSURANCES OF REGULATORY APPROVAL
   
  The Company's research and development activities, preclinical studies and
clinical trials, and ultimately the manufacturing, marketing and labeling of
its products, if approved, are subject to extensive regulation by FDA and
foreign regulatory authorities. To market product candidates currently under
development, the Company must undergo an extensive regulatory approval
process. The regulatory process takes many years and requires the expenditure
of substantial resources. Although protocols for clinical trials are submitted
to FDA prior to commencement of the trials, there can be no assurance that FDA
will accept the clinical trials as adequate or well-controlled or accept the
results of those trials. Similarly, FDA may determine that product candidates
are not eligible for or will not receive expedited review, whether or not FDA
has previously indicated that such product candidates may be eligible for
expedited review. In addition, delays or rejections may result from changes in
FDA policies about drug approval during the period of product development,
from FDA review of NDAs, and from other causes. Similar delays may also be
encountered in foreign countries. There can be no assurance that regulatory
review will be conducted in a timely manner or that regulatory approval will
be obtained for any drugs developed by the Company, including ERGOSET.
Moreover, if regulatory approval of a drug is granted, the approval may entail
limitations on the indicated uses for which it may be marketed. Further, even
if regulatory approval is obtained, a company's marketed drug, its bulk
chemical supplier, its manufacturer and its manufacturing facilities are
subject to continual review and periodic inspections, and later discovery of
previously unknown problems with a product, supplier, manufacturer or facility
may result in restrictions on the product, including a withdrawal of the
product from the market. Failure to comply with the applicable regulatory
requirements can, among other things, result in fines, suspensions of
regulatory approvals, product recalls, operating restrictions and criminal
prosecution. Additional government regulation may be established that could
prevent or delay regulatory approval of the Company's product candidates.     
 
                                       6
<PAGE>
 
  The Company's business is also subject to regulation under state and federal
laws regarding environmental protection and hazardous substances control,
including the Occupational Safety and Health Act, the Environmental Protection
Act, and the Toxic Substance Control Act. There can be no assurance that
statutes or regulations applicable to the Company's business will not be
adopted that impose substantial additional costs or otherwise materially
adversely affect the Company's operations. See "Business--Government
Regulation."
 
UNCERTAINTIES RELATED TO PRODUCT DEVELOPMENT AND MARKETABILITY
 
  The Company has not yet completed the development of any products and,
accordingly, has not begun to market or generate revenues from the
commercialization of products. ERGOSET recently completed testing in two Phase
III clinical trials as adjunctive therapy in obese patients suffering from
Type II diabetes. ERGOSET as monotherapy for Type II diabetes, obesity or
other indications and the Company's other product candidates are at earlier
stages of development. There can be no assurance that the Company will
successfully develop and market its product candidates, which lack of success
would have a material adverse effect on the Company.
 
  The results of preclinical studies and initial clinical trials of the
Company's product candidates are not necessarily predictive of the results
from large-scale clinical trials. The Company must demonstrate through
preclinical studies and clinical trials that its product candidates are safe
and effective for use in each target indication before the Company can obtain
regulatory approvals for the commercial sale of those products. These studies
and trials may be very costly and time-consuming. The speed with which the
Company is able to enroll patients in clinical trials is an important factor
in determining how quickly clinical trials may be completed. Many factors
affect patient enrollment, including the size of the patient population, the
proximity of patients to clinical sites, and the eligibility criteria for the
study. Delays in patient enrollment may result in increased costs, trial
delays, or both, which could have a material adverse effect on the Company.
Even if the Company establishes the safety and efficacy of its product
candidates and obtains FDA and other regulatory approvals for its product
candidates, physicians may not prescribe the approved product. Also, there can
be no assurance that the Company's product candidates will be accepted as
producing clinically significant benefits.
 
  The administration of any product the Company develops may produce
undesirable side effects in humans. The occurrence of side effects could
interrupt or delay clinical trials of product candidates and could result in
FDA's or other regulatory authorities' denying approval of the Company's
product candidates for any or all targeted indications. The Company, FDA or
other regulatory authorities may suspend or terminate clinical trials at any
time. Even if the Company receives FDA and other regulatory approvals, the
Company's product candidates may later exhibit adverse effects that limit or
prevent their widespread use or that necessitate their withdrawal from the
market. There can be no assurance that any of the Company's product candidates
will be safe for human use.
 
MANUFACTURING UNCERTAINTIES; RELIANCE ON THIRD-PARTY SUPPLIERS
 
  The Company does not operate and does not plan to operate manufacturing
facilities for the production of either bulk chemicals or the pharmaceutical
dosage forms for its product candidates. The Company has entered into a United
States supply agreement with Geneva Pharmaceuticals, Inc. ("Geneva") for the
finished dosage forms of ERGOSET. If Geneva does not perform its obligations
under this agreement or if the agreement is terminated, the Company may not be
able to obtain supplies of ERGOSET. Even if the Company is able to obtain
ERGOSET from other suppliers, it may not be on the terms or in the quantities
acceptable to the Company. Like Geneva, other suppliers would need to meet FDA
manufacturing requirements, and there can be no assurance that they would
receive FDA approval. The active ingredient in ERGOSET, bromocriptine, is
available from few suppliers in the world, and the manufacturing process for
the active ingredient is complex and lengthy. Accordingly, the Company will
encounter significant delays if it must obtain supplies from other sources or
otherwise experiences interruptions in its supplies. See "Business--
Commercialization Strategy--Manufacturing." If the Company is unable to obtain
adequate supplies, its business would be materially adversely affected. The
Company and Geneva have recently begun development of additional dosage-
strength tablets. This activity is subject to FDA requirements, including
demonstration of satisfactory in vitro dissolution, bioavailability,
bioequivalence, and manufacturability. There can be no assurance of the
outcome of these activities or the times in which they may be completed, if at
all.
 
                                       7
<PAGE>
 
LIMITED SALES AND MARKETING EXPERIENCE; DEPENDENCE ON FUTURE COLLABORATORS
 
  The Company has limited experience in sales, marketing and distribution. To
market any of its product candidates directly, the Company must develop a
sales and marketing force with supporting distribution capability; otherwise
the Company must enter into marketing and distribution arrangements with a
company that has an established capability. Significant additional
expenditures, management resources and time will be required for the Company
to develop a sales and marketing force and supporting distribution capability.
The Company plans to enter into a marketing agreement with one or more
pharmaceutical companies that have established marketing and sales
capabilities. To the extent that the Company enters into marketing or
distribution arrangements with others, any revenues the Company receives will
depend upon the efforts of third parties. While the Company believes that its
potential collaborators will have an economic incentive to succeed in
performing their obligations under such arrangements, the amount and timing of
funds and other resources to be devoted under such arrangements will be
controlled by the other parties and will be subject to financial and other
difficulties that may befall the other parties. There can be no assurance that
any third party will market the Company's products successfully or that any
third-party collaboration will be on terms favorable to the Company. If any
marketing partner does not market a product successfully, the Company's
business would be materially adversely affected. There can be no assurance
that the Company will be able to establish sales, marketing and distribution
capabilities, that it will be able to enter into a collaborative marketing
agreement, or that it or its collaborators will be successful in gaining
market acceptance for any products that the Company may develop. The Company's
failure to establish marketing capabilities or to enter into marketing
arrangements with third parties would have a material adverse effect on the
Company.
 
NO ASSURANCE OF ADEQUATE THIRD-PARTY REIMBURSEMENT
 
  The Company's ability to commercialize its product candidates successfully,
if FDA approval is obtained, will depend in part on the extent to which
appropriate reimbursement levels for the cost of the products and related
treatment are obtained from government authorities, private health insurers
and other organizations, such as health maintenance organizations ("HMOs").
Third-party payors are increasingly challenging pricing of pharmaceutical
products. In addition, the trend toward managed healthcare in the United
States, the growth of organizations such as HMOs, and legislative proposals to
reform healthcare and government insurance programs could significantly
influence the purchase of pharmaceutical products, resulting in lower prices
and reducing demand for the Company's product candidates. Such cost
containment measures and healthcare reform could affect the Company's ability
to sell its product candidates and may have a material adverse effect on the
Company.
 
  Significant uncertainty exists about the reimbursement status of newly
approved pharmaceutical products. There can be no assurance that reimbursement
in the United States or foreign countries will be available for any of the
Company's product candidates, that any reimbursement granted will be
maintained, or that limits on reimbursement available from third-party payors
will not reduce the demand for, or negatively affect the price of, the
Company's product candidates. The unavailability or inadequacy of third-party
reimbursement for the Company's product candidates would have a material
adverse effect on the Company. The Company is unable to forecast what
additional legislation or regulation relating to the healthcare industry or
third-party coverage and reimbursement may be enacted in the future, or what
effect the legislation or regulation would have on the Company's business.
 
EARLY STAGE OF DEVELOPMENT; HISTORY OF OPERATING LOSSES; ANTICIPATION OF
FUTURE LOSSES
 
  The Company is in a development stage. It has generated no revenues from
product sales, and it does not expect to generate revenue from product sales
for several years, if at all. As of March 31, 1996, the Company's accumulated
deficit was $45,776,394. To date, the Company has dedicated most of its
financial resources to ERGOSET research and development, general and
administrative expenses, and the prosecution of patents and patent
applications. The Company expects to incur significant and increasing
operating losses for at least the next several years, primarily owing to the
expansion of its research and development programs, including
 
                                       8
<PAGE>
 
preclinical studies and clinical trials. The Company's ability to achieve
profitability will depend, among other things, on its successfully completing
development of its product candidates, obtaining regulatory approvals,
establishing manufacturing, sales and marketing capabilities or collaborative
arrangements, and raising sufficient funds to finance its activities. There
can be no assurance that the Company will be able to achieve profitability or
that profitability, if achieved, can be sustained. See "Selected Consolidated
Financial Data," "Management's Discussion and Analysis of Financial Condition
and Results of Operations," and "Business."
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING
 
  The Company has experienced negative cash flows from operations since its
inception and has funded its activities to date primarily from issuances of
equity securities. The Company has expended, and will continue to require,
substantial funds to continue research and development, including preclinical
studies and clinical trials of its product candidates, and to commence sales
and marketing efforts if regulatory approvals are obtained. The Company's
capital requirements will depend on many factors, including the problems,
delays, expenses and complications frequently encountered by development stage
companies; the progress of the Company's research, development and clinical
trial programs; the extent and terms of any collaborative research,
manufacturing, marketing or other funding arrangements; the costs and timing
of seeking regulatory approvals of the Company's product candidates; the
Company's ability to obtain regulatory approvals; the success of the Company's
sales and marketing programs; costs in filing, prosecuting, defending and
enforcing any patent claims and other intellectual property rights; and
changes in economic, regulatory or competitive conditions or the Company's
planned business. Estimates about the adequacy of funding for the Company's
activities are based on certain assumptions, including the assumption that
testing and regulatory procedures relating to the Company's product candidates
can be conducted at projected costs. To satisfy its capital requirements, the
Company may seek to raise funds in the public or private capital markets. The
Company's ability to raise additional funds in the public or private markets
will be adversely affected if the results of ongoing or future clinical trials
are not favorable or if regulatory approval for any of the Company's product
candidates is not obtained. The Company may seek additional funding through
corporate collaborations and other financing vehicles. There can be no
assurance that any such funding will be available to the Company, or, if
available, that it will be available on acceptable terms. If adequate funds
are not available, the Company may be required to curtail significantly one or
more of its research or development programs, or it may be required to obtain
funds through arrangements with future collaborative partners or others that
may require the Company to relinquish rights to some or all of its
technologies or product candidates. If the Company is successful in obtaining
additional financing, the terms of the financing may have the effect of
diluting or adversely affecting the holdings or the rights of the holders of
Common Stock. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."
 
UNCERTAINTY OF PROTECTION FOR PATENTS AND PROPRIETARY TECHNOLOGY
 
  The Company's ability to commercialize any product candidates will depend,
in part, upon its or its licensors' ability to obtain patents, enforce those
patents, preserve trade secrets, and operate without infringing upon the
proprietary rights of third parties. In addition, the Company's patent
portfolio for its current product candidates is based on the timed
administration of neurotransmitter modulating drugs to address abnormalities
of the neuroendocrine system. If similar benefits could be achieved by using
such drugs without timed administration, the Company's patents and proprietary
technology would not prevent that use, and the use would likely have a
material adverse effect on the Company. There can be no assurance that the
patent applications licensed to or owned by the Company will result in issued
patents, that patent protection will be secured for any particular technology,
that any patents that have been or may be issued to the Company or its
licensors will be valid or enforceable, or that any patents will provide
meaningful protection to the Company.
 
  In general, the United States patents and patent applications owned by or
licensed to the Company are method-of-use patents that cover the timed use of
certain compounds to treat specified conditions. The U.S. patents for
bromocriptine, the active ingredient in ERGOSET, have expired, and
composition-of-matter
 
                                       9
<PAGE>
 
   
protection is not available for the active ingredient. Bromocriptine is
currently sold in the United States and other markets for several uses other
than the treatment of Type II diabetes or obesity. Even in jurisdictions where
the timed use of bromocriptine for Type II diabetes may be covered by the
claims of a use patent licensed to the Company, off-label sales might occur,
especially if another company markets bromocriptine at a price that is less
than the price of ERGOSET, thereby potentially reducing the sales of ERGOSET.
See "Business--Competition" and "Business--Government Regulation."     
 
  The patent positions of biotechnology and pharmaceutical companies are
highly uncertain and involve complex legal and factual questions. There can be
no assurance that patents will issue from the patent applications filed by the
Company or its licensors or that the scope of any claims granted in any patent
will provide proprietary protection or a competitive advantage to the Company.
There can be no assurance that the validity or enforceability of patents
issued or licensed to the Company will not be challenged by others or that, if
challenged, a court will find the patents to be valid and enforceable. In
addition, there can be no assurance that competitors will not be able to
circumvent any patents issued or licensed to the Company.
   
  There can be no assurance that the manufacture, use or sale of the Company's
product candidates will not infringe patent rights of others. The Company may
be unable to avoid infringement of those patents and may have to seek a
license, defend an infringement action, or challenge the validity of the
patents in court. There can be no assurance that a license will be available
to the Company, if at all, upon terms and conditions acceptable to the Company
or that the Company will prevail in any patent litigation. Patent litigation
is costly and time consuming, and there can be no assurance that the Company
will have sufficient resources to pursue such litigation. If the Company does
not obtain a license under such patents, is found liable for infringement, or
is not able to have such patents declared invalid, the Company may be liable
for significant money damages, may encounter significant delays in bringing
products to market, or may be precluded from participating in the manufacture,
use or sale of products or methods of treatment requiring such licenses. There
can be no assurance that the Company has identified United States and foreign
patents that pose a risk of infringement.     
   
  The Company recently began a small study of two drugs in the treatment of
breast cancer. The Company is aware of two issued patents, owned by a third
party, some of the claims of which relate to one of the drugs being tested in
the breast cancer study. The Company believes that the relevant claims are
either invalid or not infringed by the Company's product candidate and method
of treatment. If it is determined that any of such relevant claims are
infringed by the Company's product candidate and not invalid, the Company may
have to seek a license, defend an infringement action, or challenge the
validity of such patents in court. There can be no assurance that a license
will be available to the Company, that the terms and conditions of any such
license would be acceptable to the Company or that the Company will prevail in
any patent litigation. If the Company does not obtain a license, is found
liable for infringement, or is not able to have the relevant claims declared
invalid, then the Company may be liable for significant money damages, may
encounter significant delays, or may be precluded from participating in the
manufacture, use or sale of products or methods of treatment covered by such
patents.     
 
  Ergo also relies on trade secrets and other unpatented proprietary
information in its product development activities. To the extent that the
Company relies on trade secrets and unpatented know-how to maintain its
competitive technological position, there can be no assurance that others may
not independently develop the same or similar technologies. The Company seeks
to protect trade secrets and proprietary knowledge, in part through
confidentiality agreements with its employees, consultants, advisors and
collaborators. Nevertheless, these agreements may not effectively prevent
disclosure of the Company's confidential information and may not provide the
Company with an adequate remedy in the event of unauthorized disclosure of
such information. If the Company's employees, scientific consultants or
collaborators develop inventions or processes independently that may be
applicable to the Company's product candidates, disputes may arise about
ownership of proprietary rights to those inventions and processes. Such
inventions and processes will not necessarily become the Company's property,
but may remain the property of those persons or their employers. Protracted
and costly litigation could be necessary to enforce and determine the scope of
the Company's proprietary rights. Failure to
 
                                      10
<PAGE>
 
obtain or maintain patent and trade secret protection, for any reason, would
have a material adverse effect on the Company. See "Business--Patents,
Proprietary Rights and Licenses."
 
  The Company's rights to ERGOSET and its other technologies derive primarily
from a license from Louisiana State University ("LSU") for certain patents and
patent applications. The Company is a co-owner of certain of these patents and
patent applications. The Company has a right of first negotiation for new
technologies that LSU develops relating to the licensed technologies. There
can be no assurance that the Company will successfully obtain rights to any
such new technologies. If the license with LSU is terminated for any reason,
the Company would no longer possess the rights necessary to commercialize
ERGOSET and certain other technologies relating to the timed administration of
neurotransmitter modulating drugs. This would have a material adverse effect
on the Company. See "Business--LSU Agreement."
 
  The Company engages in collaborations, sponsored research agreements, and
other arrangements, such as the LSU Agreement, with academic researchers and
institutions that have received and may receive funding from United States
government agencies. As a result of these arrangements, the U.S. government or
certain third parties may have rights in certain inventions developed during
the course of the performance of such collaborations and agreements as
required by law or such agreements.
 
  Several bills affecting patent rights have been introduced in the United
States Congress. These bills address various aspects of patent law, including
publication, patent term, re-examination, subject matter and enforceability.
It is not certain whether any of these bills will be enacted into law or what
form new laws may take. Accordingly, the effect of legislative change on the
Company's intellectual property estate is uncertain.
 
COMPETITION AND TECHNOLOGICAL CHANGE
 
  The Company is engaged in pharmaceutical product development characterized
by extensive research efforts and rapid technological progress. Although the
Company is not aware of any other company attempting to treat Type II
diabetes, obesity or other metabolic diseases by altering daily neuroendocrine
patterns, many established biotechnology and pharmaceutical companies,
universities, and other research institutions with resources significantly
greater than the Company's are developing products that directly compete with
the Company's products. Those entities may succeed in developing products that
are safer, more effective or less costly than the Company's product
candidates. Many drugs are commercially available for the treatment of Type II
diabetes, including two drugs (Acarbose(R) and Glucophage(R)) that have
recently been approved by FDA. It appears that Glucophage is rapidly gaining
market acceptance as a therapy for Type II diabetes. There can be no assurance
that ERGOSET will be able to compete successfully with any of those products
if regulatory approval is received. In addition, ERGOSET promotional
activities will be limited to the claims on the product label approved by FDA.
Other companies may be more successful in marketing their products than the
Company because of greater financial resources, stronger sales and marketing
efforts, and other factors. If the Company commences significant commercial
sales of its products, it or its collaborators will compete in areas in which
the Company has little or no experience such as manufacturing and marketing.
See "Business--Competition."
 
  The active ingredient in ERGOSET is approved by FDA for indications other
than Type II diabetes. Physicians may choose to prescribe other drugs
containing this active ingredient for off-label use to try to achieve the same
effects as ERGOSET. Substitution of other forms of the active ingredient may
have a material adverse effect on the market for ERGOSET. This risk could be
increased if current regulations prohibiting off-label marketing are changed.
See "Business--Patents, Proprietary Rights and Licenses" and "Business--
Government Regulation." There can be no assurance that the Company's product
candidates, if commercialized, will be accepted and prescribed by healthcare
professionals. See "Business--Competition."
 
CONTROL BY EXISTING STOCKHOLDERS
 
  Upon completion of this offering, directors, executive officers and
principal stockholders of the Company, and certain of their affiliates, will
beneficially own approximately 50% of the outstanding Common Stock
 
                                      11
<PAGE>
 
(approximately 49% if the Underwriters exercise their over-allotment option in
full). Accordingly, these stockholders, individually and as a group, may be
able to influence the outcome of stockholder votes, including votes concerning
the election of directors, the adoption or amendment of provisions in the
Company's Amended and Restated Certificate of Incorporation (the "Certificate
of Incorporation"), and the approval of mergers and other significant
corporate transactions. These levels of concentrated ownership by a few
persons, along with the factors described in "Risk Factors--Anti-Takeover
Provisions," may have the effect of delaying or preventing a change in the
management or voting control of the Company. See "Principal and Selling
Stockholders."
 
POTENTIAL PRODUCT LIABILITY; AVAILABILITY OF INSURANCE
 
  The Company risks exposure to product liability claims if the use of its
products is alleged to have an adverse effect on subjects or patients. This
risk exists for product candidates tested in human clinical trials as well as
products that are sold commercially, if any. There can be no assurance that
product liability claims, if made, would not result in a recall of the
Company's products or a change in the indications for which they may be used.
The Company maintains product liability insurance coverage for claims arising
from the use of its product candidates in clinical trials. There can be no
assurance that this coverage will be adequate to cover claims. Product
liability insurance is becoming increasingly expensive, however, and no
assurance can be given that the Company will be able to maintain such
insurance, obtain additional insurance, or obtain insurance at a reasonable
cost or in sufficient amounts to protect the Company against losses that could
have a material adverse effect on the Company. Further, there can be no
assurance that the Company will be able to obtain product liability insurance
for the administration of its product candidates, including ERGOSET, in the
future or that such insurance and the resources of the Company would be
sufficient to satisfy any liability resulting from product liability claims.
In addition, the loss of coverage for the administration of the Company's
product candidates would be a breach of the terms of the Company's agreements
with LSU and Geneva, which could lead to termination of those agreements.
Termination of either agreement would have a material adverse effect on the
Company. See "Business--Commercialization Strategy--Manufacturing" and
"Business--LSU Agreement."
 
DEPENDENCE ON KEY PERSONNEL
 
  The success of the Company depends in large part on the Company's ability to
attract and retain highly qualified scientific and management personnel. The
Company faces competition for such personnel from other companies, research
and academic institutions, government entities and other organizations. There
can be no assurance that the Company will be successful in hiring or retaining
key personnel. See "Business--Competition," "Business--Human Resources" and
"Management--Directors and Executive Officers."
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
  Sales of a substantial number of shares of Common Stock in the public market
following this offering could adversely affect the market price for the Common
Stock. Approximately 5,957,178 shares of Common Stock will be eligible for
sale beginning April 27, 1997, subject to compliance with the manner-of-sale,
volume and other limitations of Rule 144. The SEC has proposed an amendment to
Rule 144 that, if adopted, would permit those shares to be sold earlier. See
"Shares Eligible for Future Sale." Some investors have the right to require
the Company to register the public resale of their shares before that time.
See "Description of Capital Stock--Registration Rights."
 
POSSIBLE STOCK PRICE VOLATILITY
 
  The trading price of the Common Stock and the price at which the Company may
sell securities in the future could be subject to large fluctuations in
response to announcements of research activities, technological innovations or
new products by the Company or its competitors, changes in government
regulations, developments concerning proprietary rights, formation or
termination of corporate alliances, quarterly variations in operating results,
litigation, clinical trials of product candidates, approval or denial of NDAs,
other FDA action

or inaction, general market and economic conditions, the liquidity of the
Company and its ability to raise additional funds, and other events. The
market prices for securities of emerging biotechnology companies have
experienced extreme fluctuations in recent years. These fluctuations have
sometimes been unrelated to the operating performance of the affected
companies. These market fluctuations as well as general fluctuations in the
stock markets may also affect the price of the Common Stock. See "Price Range
of Common Stock."
 
ANTI-TAKEOVER PROVISIONS
 
  The Company's Certificate of Incorporation (i) provides for staggered terms
of office for directors; (ii) requires certain procedures to be followed and
time periods to be met for any stockholder to propose matters to be considered
at annual meetings of stockholders, including nominating directors for
election at those meetings; (iii) prohibits stockholders from calling special
meetings of stockholders; and (iv) authorizes the Board of Directors of the
Company to issue up to 10,000,000 shares of preferred stock without
stockholder approval and to set the rights, preferences, and other
designations, including voting rights, of those shares as the Board of
Directors may determine. These provisions, alone or in combination with each
other and with the matters described in "Risk Factors--Control by Existing
Stockholders," may discourage transactions involving actual or potential
changes of control of the Company, including transactions that otherwise could
involve payment of a premium over prevailing market prices to holders of
Common Stock. The Company also is subject to provisions of the Delaware
General Corporation Law that may make some business combinations more
difficult. See "Description of Capital Stock--Delaware Law and Certain Charter
Provisions."
 
IMMEDIATE AND SUBSTANTIAL DILUTION; ABSENCE OF DIVIDENDS
 
  Purchasers of the Common Stock in the offering will experience an immediate
and substantial dilution in net tangible book value per share. These investors
will also experience additional dilution upon the exercise of outstanding
options. See "Dilution." The Company intends to retain earnings, if any, for
use in its business and does not anticipate paying any cash dividends. In
addition, the terms of the Company's Series D Preferred Stock prohibit the
Company from paying cash dividends on the Common Stock. See "Dividend Policy"
and "Description of Capital Stock--Series D Preferred Stock."

                                  THE COMPANY
 
  The Company's predecessor, Ergo, Inc., was incorporated in Rhode Island on
January 23, 1990, to develop novel treatments for metabolic disorders
including Type II diabetes and obesity. In 1992, Ergo Science Incorporated was
incorporated in Delaware and succeeded to the business of Ergo, Inc. Ergo
Science Corporation was incorporated in Delaware on December 7, 1994, as a
wholly owned subsidiary of Ergo Science Incorporated under the name Ergo
Science Holdings, Incorporated. In April 1995, the business was recapitalized
in a transaction in which the stock of Ergo Science Incorporated was exchanged
for stock of Ergo Science Holdings, Incorporated. After the recapitalization,
Ergo Science Holdings, Incorporated, changed its name to Ergo Science
Corporation. References in this Prospectus to Ergo or the Company include its
subsidiaries and predecessors. The Company's principal executive offices are
located at Charlestown Navy Yard, 100 First Avenue, Charlestown, Massachusetts
02129-2051. The Company's telephone number is (617) 241-6800.
 
                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 2,500,000 shares of
Common Stock offered hereby are estimated to be approximately $39,500,000
after deducting the estimated underwriting discounts and commissions and
offering expenses ($45,492,500 if the Underwriters exercise their over-
allotment option in full).     
 
  The Company intends to use the net proceeds for clinical trials of ERGOSET
for Type II diabetes, obesity, and breast cancer, preclinical studies and
other clinical trials, research and development, and general corporate
purposes. Allocation of the proceeds for such purposes and the timing of the
expenditures will vary depending on numerous factors, including the hiring of
additional personnel, the progress of the Company's research and development
programs, the results of preclinical studies and clinical trials of its
product candidates, the cost, timing and nature of regulatory approvals, if
any, technological advances, the commercial potential of its products, the
terms of any collaborative arrangements that the Company establishes, and the
status of competitive products. See "Risk Factors" and "Business." Pending
such uses, the net proceeds will be invested in short-term, interest bearing,
investment grade securities. The Company intends to invest and use the net
proceeds so as not to be considered an investment company under the Investment
Company Act of 1940.

                                   DILUTION
   
  The Company's net tangible book value at March 31, 1996, was $13,709,877, or
$1.35 per share of Common Stock. Net tangible book value per share is
determined by dividing the tangible net worth of the Company (tangible assets
less total liabilities and the carrying value of the Series D Preferred Stock)
by the total number of shares of Common Stock outstanding. After giving effect
to the Company's receipt of the estimated net proceeds from the sale of the
2,500,000 shares of Common Stock offered hereby at an assumed offering price
of $17, the Company's net tangible book value at March 31, 1996, would have
been $53,209,877, or $4.20 per share of Common Stock. This represents an
immediate increase in the net tangible book value of $2.85 per share to the
Company's existing holders of Common Stock and an immediate dilution of $12.80
per share to new investors purchasing shares in this offering. The following
table illustrates the per share dilution to new investors:

  The preceding table assumes no exercises of any stock options to purchase
Common Stock outstanding at March 31, 1996. The table also reflects that the
Series D Preferred Stock will remain outstanding. See "Description of Capital
Stock--Series D Preferred Stock" and Note 7 of Notes to Consolidated Financial
Statements. At March 31, 1996, there were 1,178,575 shares of Common Stock
issuable upon exercise of outstanding options with a weighted average exercise
price of $4.57 per share. See "Management--Employee Benefit Plans" and Note 9
of Notes to Consolidated Financial Statements. To the extent outstanding
options are exercised, there will be further dilution in net tangible book
value per share of Common Stock to new investors.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  Since inception, the Company has been engaged in the discovery and
development of novel treatments for metabolic disorders and cancer. The
Company has dedicated most of its financial resources to ERGOSET research and
development, general and administrative expenses, and the prosecution of
patents and patent applications. To date, the Company has not received any
revenues from the sale of products and does not expect to generate revenues
for several years, if at all. The Company has been unprofitable since its
inception, and the Company's accumulated deficit was $45,776,394 as of March
31, 1996. Although the Company intends to enter into collaborative
relationships, it expects to incur substantial and increasing losses for at
least the next several years, due primarily to the expansion of its research
and development programs, including preclinical studies and clinical trials.
The Company expects that losses will fluctuate from quarter to quarter and
that the fluctuations may be substantial.
 
RESULTS OF OPERATIONS
 
 Three Months Ended March 31, 1995, and March 31, 1996
 
  Total revenues increased from $17,267 for the three months ended March 31,
1995, to $270,402 for the same period in 1996. Revenues were derived primarily
from interest income earned on cash, cash equivalents and short-term
investments. The increase in interest income is attributable to an increase in
the average amounts of cash, cash equivalents and short-term investments
during the first quarter of 1996, compared to the first quarter of 1995. These
amounts increased as a result of proceeds received from the Company's initial
public offering in December 1995.
 
  Research and development expenses increased from $1,961,192 for the three
months ended March 31, 1995, to $3,095,159 for the same period in 1996. The
increase was principally the result of greater expenses related to Phase III
clinical trials for ERGOSET, continued progress on several early stage
research and development programs including those in metastatic breast cancer
and photodynamic therapy, and the hiring of additional research personnel.
 
  General and administrative expenses decreased from $1,930,450 for the three
months ended March 31, 1995, to $1,073,128 for the same period in 1996. The
decrease was principally due to a net charge of $1,089,356 recorded in the
first quarter of 1995 related to a renegotiated supply agreement. Excluding
this nonrecurring, non-cash charge, general and administrative expenses
increased $232,034 in the first quarter of 1996, compared to the first quarter
of 1995. The increase was mainly due to the hiring of additional
administrative personnel.
 
  Net loss increased from $3,874,375 to $3,897,885 while net loss to common
stockholders decreased from $4,142,656 to $4,004,535 for the three months
ended March 31, 1995 and 1996, respectively. Although the change in net loss
to common stockholders was minor, the net loss per common share decreased from
$(1.07) for the three months ended March 31, 1995, to $(.39) for the same
period in 1996. The decrease was attributable to the change in weighted
average common shares outstanding resulting from the Company's initial public
offering in December 1995. For the three months ended March 31, 1995, the
weighted average common shares outstanding was 3,887,838, compared to
10,146,899 for the same period in 1996.
 
 Years Ended December 31, 1994, and December 31, 1995
 
  Total revenues declined from $214,916 in 1994 to $94,348 in 1995. Revenues
were derived primarily from interest income earned on cash and cash
equivalents. The decrease in interest income is attributable to a decrease in
the average amounts of cash and cash equivalents during 1995, compared to
1994, as cash was used to fund the Company's operations.
 
  Research and development expenses increased from $4,917,830 in 1994 to
$15,663,990 in 1995. The increase was principally the result of greater
expenses related to clinical trials of ERGOSET, the purchase of in-process
research and development, a license payment to LSU, and preclinical studies.
 
  General and administrative expenses increased from $4,256,934 in 1994 to
$6,580,308 in 1995. The increase was principally due to a net charge of
$1,747,931 related to a renegotiated supply agreement, nonrecurring
 
                                      17
<PAGE>
 
charges in connection with the termination of a manufacturing agreement, the
settlement of litigation, and the hiring of additional administrative
personnel.
 
  Net loss increased from $8,959,848 in 1994 to $22,149,950 in 1995. Net loss
to common stockholders increased from $9,893,064 to $31,960,562 while net loss
per common share increased from $2.56 in 1994 to $8.06 in 1995.
 
 Years Ended December 31, 1993, and December 31, 1994
 
  Total revenues increased from $107,710 in 1993 to $214,916 in 1994. Revenues
in 1993 and 1994 were derived primarily from interest income earned on cash
and cash equivalents. The increase in revenues from 1993 to 1994 is due
primarily to an increase in the average amounts of cash and cash equivalents
on hand during 1994 as the Company raised additional funds.
 
  Research and development expenses increased from $2,403,683 in 1993 to
$4,917,830 in 1994. This increase was principally a result of greater
expenditures for clinical trials of ERGOSET and greater expenditures for
preclinical studies.
 
  General and administrative expenses increased from $3,165,038 in 1993 to
$4,256,934 in 1994. This increase was primarily due to increased staffing
levels and legal costs associated with litigation which has since been
settled.
 
NET OPERATING LOSS CARRYFORWARD
 
  As of December 31, 1995, the Company's reported federal net operating loss
carryforwards were approximately $30 million. If not used, the tax loss
carryforwards will begin to expire in 2007. The Company's ability to use these
carryforwards is subject to limitations resulting from an ownership change as
defined in Internal Revenue Code Sections 382 and 383. See Note 5 of Notes to
Consolidated Financial Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since its inception, the Company's primary source of cash has been from
financing activities, which have consisted of private placements of equity
securities and its initial public offering. Private placements of equity
securities through March 31, 1996, provided the Company with aggregate
proceeds of $32,999,000. On December 19, 1995, the Company raised $23,030,476
from the sale of stock in an initial public offering, net of commissions and
offering costs. Cash and cash equivalents were $15,896,373 and $8,177,095,
while short-term investments were $6,325,502 and $8,860,301, at December 31,
1995, and March 31, 1996, respectively. The decrease in cash and cash
equivalents at March 31, 1996, was due primarily to a shift in the Company's
investment portfolio to include more short-term investments and the funding of
the Company's operations.
 
  The Company's primary use of cash to date has been in operating activities
to fund research and development, including preclinical studies and clinical
trials, and general and administrative expenses. As of March 31, 1996, the
Company's net investment in equipment and leasehold improvements was
$2,210,396. The Company expects that additional equipment and facilities will
be needed to the extent it increases its research and development activities.
 
  The Company believes that the net proceeds of this offering, together with
available cash, cash equivalents, short-term investments and expected interest
income, will be adequate to fund its current and anticipated levels of
operations through 1998. Before then, the Company will need to raise
additional capital through the sale of securities in the public or private
equity markets or by entering into a collaborative arrangement with another
company. See "Business--Commercialization Strategy." There can be no
assurance, however, that events in the Company's research and development
programs or other events affecting the Company's operations will not result in
accelerated or unexpected expenditures. The Company is pursuing additional
research and development of ERGOSET and other product candidates to treat
obesity, breast cancer and other diseases. The Company will require additional
financing to expand and complete that research and development. To the extent
the Company raises additional capital by issuing equity securities, ownership
dilution to existing stockholders will result and future investors may be
granted rights superior to those of existing stockholders. There can be no
assurance, however, that additional financing will be available from any
source or, if available, will be available on acceptable terms. See "Risk
Factors--Future Capital Needs; Uncertainty of Additional Funding."
 
  The terms of the Series D Preferred Stock prohibit the Company from paying
dividends on the Common Stock. See "Dividend Policy" and "Description of
Capital Stock--Series D Preferred Stock."

OVERVIEW
 
  Ergo Science Corporation is developing novel treatments for metabolic
disorders, including Type II diabetes and obesity, and for cancer. The
Company's technology uses orally administered neurotransmitter modulating
drugs to address abnormalities of the neuroendocrine system. The Company
believes that its approach may provide the platform for a new class of
treatments for a variety of glucose and lipid metabolic disorders and cancer.
The Company's lead drug candidate, ERGOSET(TM), is a low-dose, fast-release,
oral tablet formulation of bromocriptine, a dopamine agonist previously
approved by FDA to treat Parkinson's disease and other conditions. The Company
recently completed two Phase III clinical trials of ERGOSET as adjunctive
therapy with sulfonylurea agents for the treatment of Type II diabetes. A
preliminary analysis of the two completed Phase III clinical trials indicated
that ERGOSET improved control of glucose, triglycerides, free fatty acids, and
cholesterol in Type II diabetics. The Company anticipates completing a third
Phase III clinical trial of ERGOSET as monotherapy for Type II diabetes by the
end of 1996. The Company plans to submit an NDA to FDA for ERGOSET to treat
Type II diabetes in 1997. See "Risk Factors--Forward Looking Statements and
Associated Risks." Ergo has also conducted clinical trials of ERGOSET for the
treatment of obesity and intends to conduct additional obesity clinical trials
of ERGOSET by itself and in combination with another product candidate. Ergo
currently retains all marketing rights to its drug candidates.
 
  Ergo's preclinical studies suggest that temporal changes in neuroendocrine
activity may also play an important role in the body's regulation of immune
function and the body's ability to fight cancer. The Company is currently
enrolling patients in a small Phase II clinical trial of two neurotransmitter
modulating compounds for the treatment of metastatic breast cancer. The
Company is also evaluating the use of phototherapeutic dyes in photodynamic
therapy ("PDT") to treat various tumors. See "Business--Immune Regulation and
PDT for Cancer."
 
  The following table illustrates the general focus and status of the
Company's product development efforts.

METABOLIC DISORDERS
 
  The Company's primary focus is the treatment of Type II diabetes and
obesity. These disorders involve defects in the complex relationship between
glucose and fat metabolism. To sustain life, the human body must convert food
into glucose, a simple form of sugar, for use as a source of energy for the
body's cells. When glucose is abundant, it is converted into fat
(triglycerides) and stored in the adipose tissue for use when food is not
available. When glucose is not available from food, triglycerides in the
adipose tissue are broken down into free fatty acids that stimulate glucose
production by the liver. Insulin, which is secreted by the pancreas, plays an
important role in regulating the level of glucose in the blood stream by
stimulating the use of glucose as fuel and by inhibiting the production of
glucose in the liver. In a healthy metabolic state, a balance is maintained
between the sources and uses of glucose and the sources and uses of fat.
 
 Diabetes
 
  General. The term diabetes refers to a group of disorders that are
characterized by a single common feature: abnormally high levels of glucose in
the blood. Type I diabetes (juvenile-onset diabetes or insulin dependent
diabetes) is believed to result from the impaired function of the pancreas in
producing insulin. Type II diabetes (adult onset or noninsulin dependent
diabetes mellitus) is believed to involve a defect referred to as "insulin
resistance." Insulin resistance occurs when insulin-stimulated uptake of
glucose into peripheral cells is impaired and the inhibitory effect of insulin
on glucose production in the liver is reduced. This condition leads to
excessive blood levels of glucose (hyperglycemia). Hyperglycemia in most
diabetics is accompanied by increases in the blood levels of triglycerides,
free fatty acids, and other lipids. Type II diabetes is a chronic and
incurable disease that accounts for 90% to 95% of all diagnosed cases of
diabetes. It is a leading cause of death in the United States.
 
  Many researchers believe that Type II diabetics develop insulin resistance
first, then impaired glucose tolerance, and finally diabetes. Due to a
combination of environmental and genetic factors, people develop insulin
resistance and compensate for modest insulin resistance by secreting more
insulin to maintain control of their blood glucose levels. Despite increased
insulin production, some people lose their ability to control blood glucose
over time as their insulin resistance increases. At this stage, the person
becomes impaired glucose tolerant, a condition characterized by normal blood
glucose levels before eating and hyperglycemia after eating. When a person
loses the ability to regulate blood glucose levels and exhibits persistent
hyperglycemia, the person is considered to be a Type II diabetic.
 
  When blood glucose levels are not controlled within a narrow range, severe
complications can result. Hyperglycemia over an extended period of time is
believed to damage the walls of blood vessels, causing complications
characteristic of Type II diabetes including blindness from microvascular
deterioration in the retina, loss of circulation in the extremities leading to
amputation, coronary artery disease, and kidney failure. In addition, the high
blood levels of triglycerides, free fatty acids, and total cholesterol pose
serious health risks to the diabetic and are believed to lead to
cardiovascular disease including coronary heart disease. Approximately 70% to
80% of Type II diabetics are obese, and mortality in most Type II diabetics is
caused by cardiovascular disease and stroke, which are commonly associated
with hyperlipidemia and obesity.
 
  Need for New Diabetes Treatments. There is no cure for diabetes. After
diagnosis, the first course of therapy for Type II diabetics is to try to
control hyperglycemia through diet and exercise. If this fails to achieve
glycemic control, the patients typically begin medication. The two leading
medications for Type II diabetes have traditionally been insulin and a class
of oral drugs called sulfonylureas. Each of these drugs reduces glucose levels
by increasing serum insulin levels. Most patients initially take
sulfonylureas, which work by stimulating the production of insulin in the
pancreas. Over time, many Type II diabetics taking sulfonylureas lose their
ability to control glucose levels, and others lose their ability to secrete
insulin. In either case, the Type II diabetic must then begin daily insulin
injections. The labeling of all sulfonylureas includes a special warning on
the possible increased risk of cardiovascular mortality from the use of the
drugs. Researchers suspect that the increased risk of cardiovascular disease
may be the result of above-normal levels of serum insulin, which may stimulate
the liver to increase lipid levels in the bloodstream, contributing to
atherosclerosis and obesity. Many patients who
 
                                      20
<PAGE>
 
take sulfonylureas still experience elevated blood glucose and lipid levels.
For these reasons, there is a need for new diabetes therapies that improve
control of blood glucose and the co-morbid conditions associated with the
disease.
   
  FDA recently approved two new drugs, Acarbose (precose) and Glucophage
(metformin), for treatment of Type II diabetes. Both drugs have methods of
action that are different from sulfonylureas. Acarbose is taken orally with
each meal and blocks the enzymes necessary for the body to digest and absorb
carbohydrates. Metformin is believed to work, at least in part, by reducing
glucose output from the liver. See "Business--Competition."     
 
  Demographics and Market Size. According to the American Medical Association
and the American Diabetes Association, approximately 15 million people will
suffer from Type II diabetes in the United States in 1996, seven million have
been diagnosed with the disease, and approximately 32 million will suffer from
the disease in 2010. According to IMS America Ltd., a pharmaceutical market
research firm, sulfonylureas are a leading pharmaceutical product with annual
sales of approximately $720 million in the United States. Insulin is also a
leading pharmaceutical product with annual sales of approximately $680 million
in the United States.
 
 Obesity
 
  General. The term obesity refers to a disorder in which a person's total
body weight is more than 30% over the weight that is normal for healthy
persons of the same age and height. Obesity is generally characterized by a
low lean-to-fat body mass ratio and is often accompanied by high blood lipid
levels. While the causes of obesity vary, many researchers believe that
insulin resistance contributes to the development of obesity.
 
  Demographics and Market Size. Obesity is a significant health problem in the
United States. According to preliminary data from the 1994 National Health and
Nutrition Examination Survey, about 60 million Americans, or 45% of the adult
population, are overweight and about 35 million, or 26% of the adult
population, are obese. Obesity is considered a risk factor for Type II
diabetes. Approximately 30% of obese Americans are Type II diabetics, and many
of the others are considered to be in pre-diabetic states with varying levels
of insulin resistance or impaired glucose tolerance. Obesity is also
considered a risk factor for cardiovascular disease, gall bladder disease and
osteoarthritis. Recently, it was reported in the New England Journal of
Medicine that obesity itself can affect longevity. When statisticians ruled
out the effects of smoking, high-fat diets, lack of exercise and other
unhealthy living habits of 115,000 nurses tracked since 1976, they found that
25% of premature deaths in this study were associated with obesity.
 
THE COMPANY'S TECHNOLOGY
 
  Ergo's founding scientists, Anthony H. Cincotta, Ph.D., formerly of
Massachusetts General Hospital and Harvard Medical School, and Albert H.
Meier, Ph.D., formerly of Louisiana State University, have conducted extensive
research into the way changes in the daily patterns of neuroendocrine activity
regulate changes in glucose and lipid metabolism observed in seasonal and non-
seasonal animals as well as in the ob/ob mouse, a genetically insulin
resistant and fat animal model. Ergo has elaborated on this research to focus
on how changes in daily patterns of neuroendocrine activities may improve
disease conditions in humans.
 
 Overview of Temporal Neuroendocrine Regulation of Metabolism
 
  Many animal species become insulin resistant and fat during one season of
the year and insulin sensitive and lean during other seasons of the year.
These seasonal increases in lipid production and storage provide an energy
source to the animal to endure times of low food availability, provide energy
for migration and hibernation, and provide insulation during the winter. Thus,
many species of animals have developed this ability to become seasonally
insulin resistant and fat in order to survive adverse environmental
conditions. Researchers have observed that animals in a seasonally insulin
resistant and fat condition display a metabolic profile that is similar to the
metabolic profile of insulin resistant and obese humans who have Type II
diabetes and its related metabolic disorders.
 
 
                                      21
<PAGE>
 
  Ergo's scientists have demonstrated that the seasonally insulin resistant and
fat condition in animals is associated with seasonal changes in the daily
pattern of neuroendocrine activity. The neuroendocrine system--a complex
physiological system that includes the brain, peripheral nervous system and
hormones--is one of the mechanisms that regulate and coordinate many functions
of the body. Neurotransmitters in the hypothalamus area of the brain such as
dopamine, serotonin and noradrenalin are involved in regulating the production
of hormones by the pituitary and other endocrine glands, which in turn help
regulate various cellular activities such as the liver's production of lipids.
   
  Ergo's scientists have demonstrated that, when vertebrate animals are in a
seasonally insulin resistant, fat condition, they evidence a specific daily
pattern of neuroendocrine activity. This pattern is evidenced in part by
changes in the serum level of the hormone prolactin at specific times of day.
For example, in the Syrian hamster the concentration of the hormone prolactin
in the blood of the animal peaks at approximately four hours after sunrise each
day when the animal is in its insulin sensitive, lean summer condition. When
the animal is in its insulin resistant, fat winter condition, prolactin levels
peak at approximately 12 hours after sunrise each day. Further, Ergo's
scientists have observed that these changes in daily hormone patterns occur for
a number of different hormones and that a pattern exists in the levels of
certain hormones in the summer condition of animals that differs from the
pattern exhibited during the winter condition. The production of these hormones
is regulated by dopamine and other neurotransmitters in the hypothalamus. The
following graphs illustrate the differences between the daily pattern of
prolactin levels in the Syrian hamster during its insulin sensitive, lean
condition and the daily pattern during its insulin resistant, fat condition.
    

[Under the heading "Seasonal Neuroendocrine Profile of Syrian Hamster," two line
graphs titled "Summer Condition, Insulin Sensitive, Lean" and "Winter Condition,
Insulin Resistant, Fat," respectively, with hourly increments of time on the 
x-axis and plasma prolactin levels on the y-axis, showing prolactin levels in a 
Syrian hamster peaking at four hours after light onset in an insulin sensitive, 
lean Syrian hamster and 12 hours after light onset in an insulin resistant, fat 
Syrian hamster, appear here.]
 
                                       22
<PAGE>
 
   
  Moreover, the Company's scientists have demonstrated that the timed
administration of certain pharmaceuticals in seasonal animals can alter
neurotransmitter activity, which affect daily hormone patterns to produce the
desired seasonal metabolic conditions out of season. When neurotransmitter
modulating drugs known to affect the neuroendocrine system are administered to
a seasonally insulin resistant, fat animal at specific times designed to shift
its neuroendrocine patterns to mimic those of a seasonally insulin sensitive,
lean animal, the animal's metabolism shifts to an insulin sensitive, lean state
regardless of the actual season of the year. In studies presented at the June
1996 annual meeting of the American Diabetes Association, Ergo's scientists
measured levels of neurotransmitter metabolites in the ventral medial
hypothalamus ("VMH") of insulin resistant, fat Syrian hamsters. The studies
indicated that insulin resistant, fat Syrian hamsters became insulin sensitive
and lean in two weeks through the administration of neurotransmitter modulating
drugs at a specific time of day. The studies also indicated that the altered
condition correlated with a change in the levels of neurotransmitter
metabolites in the VMH, which evidenced an alteration in the daily
neuroendocrine patterns in the animals.     
   
  Ergo's scientists have also demonstrated that the timed administration of
certain pharmaceuticals in non-seasonal animals with insulin resistance and
obesity can alter the animal's daily neuroendocrine pattern and produce a
leaner, more insulin sensitive animal. In preclinical studies with the leptin-
deficient ob/ob mouse, a genetically insulin resistant and fat animal model,
Ergo's scientists achieved significant reductions in body fat compared with
control animals through the timed administration of neurotransmitter modulating
drugs. In one study presented at the June 1996 ADA annual meeting, Ergo's
scientists reported that the use of two neurotransmitter modulating drugs
produced a significant (between 50% and 60%) reduction in food intake and a
decrease in body fat of 22% to 32% with no significant decrease in lean body
(muscle) mass compared with control animals. The treatment also improved
glycemic control, reducing glucose 57% and insulin 50%. The following graph
illustrates that body fat, serum insulin levels, and blood glucose levels were
reduced in the treated ob/ob mouse compared with control animals.     
 
 
[Under the heading "Modifying Glucose and Lipid Metabolism in the Ob/Ob Mouse,"
three bar graphs with both a "control" and "drug" bar on the x-axis and with 
"fat pad weight," "serum insulin" levels and "blood glucose" levels on the 
y-axis, respectively, showing that body fat gain, serum insulin levels and 
blood glucose levels were reduced in the animals on drug compared with the 
control animals from approximately 3.8g to 1.7g, 9.5 ng/dl to 5.5 ng/dl and 260 
mg/dl to 140 mg/dl, respectively, appear here.]



                                       23
<PAGE>
 
   
  In a second study also presented at the 1996 ADA annual meeting, Ergo's
scientists found that the administration of a dopamine agonist and a serotonin
agonist at specific times of day produced a significant (approximately 30%)
reduction in food intake and reduced body fat 30% to 75% and body weight gain
40% to 60% in the treated ob/ob mouse compared with control animals. In that
study, lean body mass increased 5% to 17%, indicating that the two-drug
treatment reduced weight by selectively reducing body fat. The Company
believes the selective reduction in body fat and preservation of lean body
mass has significant implications for the treatment of obesity in humans
because improvement in the lean-to-fat body mass ratio may reduce
cardiovascular risk associated with chronic obesity.     
 
 Development of ERGOSET and Other Products for Metabolic Disorders
 
  Ergo's scientists believe that their data suggest that defects in glucose
and lipid metabolism are associated with a neuroendocrine abnormality that,
during the daytime, involves reduced levels of dopaminergic activity and an
excess of serotonergic and noradranergic activity, and, during the nighttime,
involves an excess of dopaminergic activity and a reduced level of
serotonergic activity. Ergo's technology employs neurotransmitter modulating
compounds to alter the daily patterns of neurotransmitter activity. These
patterns function as biological clocks that the neuroendocrine system uses to
regulate metabolism and other physiological functions such as the immune
system. The aging process, as well as changes in the environment of humans
such as diet, sedentary lifestyles, and artificial lighting, may be changing
the timing and regularity of daily neuroendocrine patterns in humans.
Accordingly, the Company's therapeutic strategy to treat metabolic disorders
is to develop neurotransmitter modulating compounds for administration at a
particular time of day to alter specific neuroendocrine patterns that are
believed to influence the regulation of glucose and lipid metabolism.
 
  The Company has developed ERGOSET, a low-dose, fast-release, oral tablet
formulation of a dopamine agonist. ERGOSET's active ingredient, bromocriptine,
has been approved by FDA to treat Parkinson's disease and other conditions.
Bromocriptine increases dopaminergic activity and decreases serotonergic
activity. ERGOSET tablets are formulated to permit titration of the drug at
low doses and to minimize gastrointestinal problems. In contrast to insulin,
which is injected, and sulfonylurea agents and metformin, which are taken
multiple times daily in varying doses, ERGOSET for Type II diabetes is a once-
daily oral therapy that may facilitate patient compliance.
   
  The primary focus of the Company's clinical trials of ERGOSET to date has
been to study the effects of the drug on glucose and lipid metabolism, with
emphasis on Type II diabetes and obesity. The Company began clinical trials of
ERGOSET during 1992, completed two Phase III clinical trials of ERGOSET as
adjunctive therapy for Type II diabetes in the first half of 1996, and
anticipates completing the Phase III clinical trial of ERGOSET as monotherapy
for Type II diabetes by the end of 1996. Ergo plans to begin additional
studies of ERGOSET for Type II diabetes using ERGOSET as adjunctive therapy
with insulin and in combination with Glucophage (metformin).     
 
  Ergo has conducted Phase II clinical trials of the use of ERGOSET to reduce
body fat in obese subjects and plans to begin enrolling patients in a separate
Phase II clinical trial of ERGOSET to treat obese patients in the first half
of 1997.
 
  The Company is in the process of selecting at least one lead candidate for
clinical development as a second generation treatment for Type II diabetes and
obesity. The possible candidates include a combination of a dopamine D2
agonist such as ERGOSET with a dopamine D1 agonist, and a therapy using a
dopamine agonist at one time of day in combination with a serotonin agonist at
another time of day. The Company is also studying additional delivery methods
to improve the therapeutic index of ERGOSET and other neurotransmitter
modulating drugs.

ERGOSET CLINICAL TRIAL OVERVIEW
 
  Ergo's three Phase III clinical trials of the timed daily administration of
ERGOSET tablets for the treatment of Type II diabetes involve over 600 obese
Type II diabetic subjects. Because the active ingredient in ERGOSET,
bromocriptine, has been approved for human use in other indications for more
than 15 years at dosage levels greater than those used in ERGOSET therapy, the
Company initiated Phase II clinical trials directly following preclinical
studies. The primary clinical endpoint of the Phase III clinical trials and
many of the Phase II clinical trials is to achieve a clinically and
statistically significant reduction in blood levels of glycated hemoglobin
A1c, an indicator of glycemic control in diabetics. The following table sets
forth general information about Ergo's Phase II and Phase III clinical trials
of ERGOSET for Type II diabetes and obesity.

ERGOSET FOR TYPE II DIABETES
 
 Phase II Clinical Trial Results
 
  The Company has conducted eight Phase II clinical trials involving over 280
patients. In these studies, the Company evaluated the relationship of abnormal
neuroendocrine profiles to defects in glucose and lipid metabolism. The
Company evaluated ERGOSET's effect on hyperglycemia, hyperinsulinemia, excess
body fat, high triglycerides and high cholesterol, as well as ERGOSET's safety
profile. The protocols for Ergo's Phase III clinical trials were developed
based on the statistical analysis of data from various subgroups of subjects
of these Phase II clinical trials.
 
  Two key Phase II clinical trials of ERGOSET for Type II diabetes were
Studies 93-2 and 94-2, which were double-blinded, placebo-controlled clinical
trials in obese, Type II diabetic subjects, most of whom were also using
sulfonylurea agents. The intent of these clinical trials was to evaluate the
timed administration of ERGOSET on glycemic control. In the first clinical
trial (Study 93-2), subjects on a weight-maintaining diet were administered
ERGOSET or placebo on a timed daily basis for 12 weeks. ERGOSET treatment
produced statistically significant reductions in total glycated hemoglobin and
fasting plasma glucose compared to placebo.
 
                                      25
<PAGE>
 
The second clinical trial (Study 94-2), involved administering ERGOSET or
placebo for 24 weeks to subjects on either a weight-reducing or weight-
maintaining diet. The trial included 83 subjects on ERGOSET as adjunctive
therapy with sulfonylurea agents and 16 subjects on ERGOSET as monotherapy.
The subjects on ERGOSET as adjunctive therapy, regardless of diet, experienced
a statistically significant reduction in glycated hemoglobin A1c and systolic
blood pressure compared to placebo. The combined population of subjects on
either ERGOSET as monotherapy or ERGOSET as adjunctive therapy who were found
to be weight-maintained experienced a statistically significant reduction in
glycated hemoglobin A1c compared to placebo. The Company recently completed
Study 94-3, an open label study of the effect of ERGOSET treatment in 12
obese, hyperinsulinemic nondiabetic females. In that study, ERGOSET produced
statistically significant reductions in fasting triglycerides and cholesterol
and post-prandial triglyceride levels compared to subjects on placebo.
 
  No clinically significant adverse safety trends arose during Phase II
clinical trials of ERGOSET. The higher dosages (10 mg to 50 mg daily) of
bromocriptine generally used to treat Parkinson's and other diseases have
revealed problems with patient tolerance, although the side effects are
generally mild. ERGOSET is a fast-release formulation of bromocriptine that
has been administered in doses from 1.6 mg to 4.8 mg daily.
 
 Phase III Clinical Trial Results
 
  During January 1995, Ergo initiated three double-blinded, placebo-controlled
Phase III clinical trials of ERGOSET treatment in obese, Type II diabetics.
The Company enrolled over 600 patients in the three clinical trials, which
include two trials of ERGOSET as adjunctive therapy that have been completed.
In the completed Phase III clinical trials, ERGOSET or placebo was given in a
single daily dose at 8:00 a.m. to approximately 500 Type II diabetics who were
on weight-maintaining diets and who were taking sulfonylurea agents. The
completed Phase III clinical trials were conducted at 17 sites across the
United States. In the ongoing monotheraphy Phase III clinical trial, ERGOSET
or placebo is being given to approximately 130 Type II diabetics who are on a
weight-maintaining diet but are not on any other diabetes medication. The
primary clinical endpoint of each of the Phase III clinical trials is to
achieve a clinically and statistically significant reduction in blood levels
of glycated hemoglobin A1c, which is considered a reliable indicator of
glycemic control in diabetics.
 
  The Company recently announced that a preliminary analysis of the two
completed Phase III trials indicated that ERGOSET improved control of glucose,
triglycerides, free fatty acids, and cholesterol in Type II diabetics. This
preliminary analysis also showed that ERGOSET was generally well-tolerated.
All subjects were overt diabetics with average baseline fasting glucose and
glycated hemoglobin Alc levels of 218 mg/dl and 9.4%, respectively, in one
study and 223 mg/dl and 9.3%, respectively, in the other study. Baseline
fasting serum triglycerides and cholesterol were 237 mg/dl and 212 mg/dl,
respectively, in one study and 259 mg/dl and 213 mg/dl, respectively, in the
other study. Baseline fasting free fatty acids were 852 u eq/L in the only
study for which this parameter is available.
 
  On an intent-to-treat basis, these trials indicated that ERGOSET improved
glycemic control as measured by a reduction in glycated hemoglobin Alc compared
with placebo of 0.5% (p less than 0.0001) in one study and 0.6% (p less than
0.0007) in the other study. Serum glucose, triglycerides, and free fatty acids
were measured nine times throughout the day (7 a.m. to 7 p.m., i.e. fasting,
postabsorptive and postprandial measurements), and ERGOSET resulted in
consistent reductions compared with placebo in each parameter. Average
reductions in serum glucose compared to placebo were 21 mg/dl (p less than
0.005) and 23 mg/dl (p less than 0.001). Average reductions in serum
triglycerides compared with placebo were 44 mg/dl (p less than 0.05) and 55
mg/dl (p less than 0.003) in the two studies. The average reduction in free
fatty acids compared with placebo was 149 u eq/L (p less than 0.03) in the one
study for which this parameter is available. ERGOSET treatment indicated a trend
toward a reduction in fasting cholesterol levels of 5.7 mg/dl (p less than 0.09)
compared with placebo in one study and a statistically significant reduction in
fasting cholesterol levels of 8.0 mg/dl (p less than 0.04) compared with placebo
in the other study.
 
  A pre-established responder criterion was designed to identify clinically
significant responders to ERGOSET shortly after the initiation of treatment.
Responders were defined as those individuals on ERGOSET who had at least a 0.3%
decrease in glycated hemoglobin Alc from baseline after eight weeks of
treatment. According to this pre-established criterion, approximately 60% of all
subjects on ERGOSET were classified as responders. In the responder group,
ERGOSET resulted in decreases in glycated hemoglobin Alc of 1.0%

                                      26

<PAGE>

(p less than 0.0001) and 1.1% (p less than 0.0001) compared with placebo and
decreases of 0.6% (p less than 0.0001) and 0.8% (p less than 0.0001) compared
with baseline. Average reductions in serum glucose levels were 39 mg/dl (p less
than 0.0001) and 37 mg/dl (p less than 0.0001) compared with placebo and 24
mg/dl (p less than 0.06) and 25 mg/dl (p less than 0.01) compared with
baseline.
 
  One study measured body density, or the ratio of lean mass to fat mass, using
a hydrodensitometry method. On an intent-to-treat basis, ERGOSET treatment
indicated a trend toward improved body density of 0.001 kg/L (p less than 0.11)
compared with placebo. On an intent-to-treat basis, body weight increased 2.0
lbs. (p less than 0.01) and 1.8 lbs. (p less than 0.003) compared to placebo in
both studies. The Company believes that the trend toward improved body density
and the reductions in triglycerides, free fatty acids and cholesterol in
subjects on a weight-maintaining diet provide evidence that a shift from fat
body mass to lean body mass may be involved in the weight gain.

  The following table summarizes the preliminary analysis of the data from the
two completed Phase III clinical trials.

  There was no statistically significant change in the levels of fasting
insulin in either study. On an intent-to-treat basis, diurnal insulin levels

increased 58 u U/ml.hr (p less than 0.005) in the other study. Compared with
placebo, these changes in insulin levels were not clinically significant.     
 
  Both systolic and diastolic blood pressure tended to decrease among all
ERGOSET treatment groups, though those decreases were not statistically

nausea, fatigue, and dizziness. The combined discontinuation rate in the two
trials due to side effects was approximately 12% for ERGOSET compared with
approximately 2% in the placebo group.

 FDA Approval Strategy
   
  The primary clinical endpoint of the Company's Phase III clinical trials is
to achieve a clinically and statistically significant reduction in blood
plasma levels of glycated hemoglobin A1c. FDA and the medical community have
accepted glycated hemoglobin A1c as an indication of efficacy for drugs for
Type II diabetes. The Company intends to file an NDA in 1997 for approval of
ERGOSET to treat Type II diabetes and intends to seek expedited review of the
NDA. If the results of the Phase III clinical trial of ERGOSET as monotherapy
for Type II diabetes are not satisfactory, the Company will not be able to
submit an NDA to FDA for ERGOSET as monotherapy. In that case, the Company may
have to conduct additional Phase III clinical trials in an effort to
demonstrate the safety and efficacy of ERGOSET as monotherapy or may have to
submit an NDA to FDA for ERGOSET as adjunctive therapy only. There can be no
assurance that FDA will agree with the Company's assessment of the results of
the Phase III clinical trials, that FDA will grant the Company expedited
review for ERGOSET, or that ERGOSET will receive FDA approval as either
adjunctive therapy or monotherapy. See "Risk Factors--Uncertainties Related to
Phase III Clinical Trial Results of ERGOSET" and "Risk Factors--Government
Regulation; No Assurances of Regulatory Approval."     
 
 Additional Studies and Second Generation Product Candidates
   
  Ergo plans to begin additional studies of ERGOSET by conducting preclinical
studies and clinical trials of ERGOSET as adjunctive therapy with insulin in
patients who require insulin injections to treat Type II diabetes. The Company
also plans to conduct preclinical studies and clinical trials using ERGOSET as
adjunctive therapy with Glucophage (metformin). Insulin is a common treatment
for advanced stages of Type II diabetes, and Glucophage appears to be gaining
market acceptance rapidly as a new therapy. Additional clinical trials are
expected to examine the effect of ERGOSET therapy on co-morbid conditions of
Type II diabetes such as hyperlipidemia. The Company plans to expand its oral
delivery system and offer ERGOSET in several dosage strengths. The Company is
currently conducting extensions to the Phase III clinical trials (principally
for safety) and bioavailability studies of different dosage strengths of
ERGOSET, which are expected to be completed in the first half of 1997. The
Company is also studying additional delivery methods to improve the
therapeutic index of ERGOSET and other neurotransmitter modulating drugs. Such
a delivery system, if developed, should allow ERGOSET's active ingredient to
be effective in lower doses than currently required. The Company is also
studying possible second generation product candidates for the treatment of
Type II diabetes and obesity, including a combination of a dopamine D2 agonist
such as ERGOSET with a dopamine D1 agonist, and a therapy using a dopamine
agonist at one time of day in combination with a serotonin agonist at another
time of day.     
 
ERGOSET FOR OBESITY
 
  Ergo's animal studies have demonstrated that neurotransmitter modulating
drugs that are effective in reducing insulin resistance in seasonal, non-
seasonal, and genetic animal models when administered at a specific time daily
are also effective in reducing total body weight and body fat and improving
the lean-to-fat mass ratio in those animal models. See "Business--The
Company's Technology."
 
  In one of Ergo's completed Phase II clinical trials using ERGOSET therapy,
the primary endpoints were the reduction in body weight and body fat in obese
human subjects. In this double-blinded, placebo-controlled Phase II clinical
trial (Study 93-3), obese subjects were placed on a 25% calorie restriction
diet and treated with either ERGOSET or placebo for an 18-week period.
Although the trial population was small, ERGOSET treatment resulted in a
statistically significant reduction in percentage of body fat compared to
placebo. This trial suggests that ERGOSET treatment may selectively reduce
body fat in obese subjects.
 
  The Company plans to begin enrolling patients in a Phase II clinical trial
of ERGOSET to treat obese patients in the first half of 1997 and plans to
pursue additional obesity clinical trials of ERGOSET by itself and in
combination with other neuromodulators to treat obesity.

IMMUNE REGULATION AND PDT FOR CANCER
 
  Breast cancer causes the second highest mortality rate from cancer among
women in the United States. In 1996, approximately 184,000 women in the United
States will be diagnosed with breast cancer. Breast cancer is now the leading
cause of death for American women aged 40 to 55. Although it was once believed
that tumors in the breast appear suddenly and spread slowly from the breast by
seeping through the lymphatic system, researchers now believe that breast
tumors take years to develop to detectable size and that they metastasize by
releasing cancerous cells into the bloodstream, from which the cells lodge and
multiply in other parts of the body.
 
  The primary treatment for breast cancer is surgical removal of the
detectable tumor and, in most cases, removal of surrounding tissue and
lymphatic systems. Surgery is generally followed by radiation therapy or
chemotherapy. All of these treatments harm healthy tissue in addition to the
diseased tissue. Radiation therapy kills cells in its target area, inducing
breast inflammation and fibroblasts, and may create genetic damage that can
lead to other forms of cancer. In addition, radiation therapy has no effect on
metastases away from the targeted area. Chemotherapeutic compounds kill cells
throughout the body, but often cause fatigue, nausea, hair loss, mouth sores,
diarrhea and premature menopause. Chemotherapy is also not believed to destroy
all metastasized cancer cells. The surviving cancer cells continue to
multiply, which often results in a recurrence of cancer. Accordingly, new
therapeutic approaches are needed to eliminate cancer cells more effectively
and to reduce damage to healthy tissue.
 
 Immune Regulation
 
  Ergo is evaluating the application of its technology to treat breast cancer
and other cancers. Preclinical studies suggest that temporal neuroendocrine
regulation may play an important role in the body's regulation of immune
function and its ability to fight cancer. The Company also believes that the
presence of cancer tumors may suppress the body's immune response to the
tumor, in part by altering the patterns of neurotransmitter activity. In a
presentation at the Ninth International Congress of Immunology in 1995, Ergo's
scientists demonstrated that the alteration of daily neuroendocrine patterns
through the timed administration of neurotransmitter modulating drugs can
stimulate the immune system and limit the growth of tumors in mice. In
addition to treating cancer, Ergo believes this approach may be useful in
treating immune system disorders such as Lupus.
 
  Ergo recently began a small, open-label Phase II clinical trial of ERGOSET
with another neurotransmitter in patients with metastatic breast cancer to
evaluate whether the treatment can increase the body's immune activity against
the cancer. Patients in this trial are dosed using ERGOSET and the
neurotransmitter alone or adjunctively with chemotherapy or radiation therapy.
 
 Photodynamic Therapy
 
  Ergo is studying the use of unique phototherapeutic dyes in PDT to fight
tumors. Preclinical studies suggest that these dyes, which are preferentially
sequestered within tumor cells, become toxic and result in site-specific,
localized destruction of tumor tissue only when irradiated with light supplied
by a laser in the proper wavelength. Many cancers that have a poor prognosis
and are difficult to treat may respond to this new approach. PDT may be useful
in treating cancers of the breast, bladder, brain, spine, pancreas and
prostate. Ergo believes its phototherapeutic dye may offer advantages over
other dyes being studied because preclinical studies indicate that Ergo's dye
is not immunosuppresive, sequesters preferentially in the tumor and not in
surrounding tissue or blood vessels, oxidizes with relatively low-intensity
photon bombardment, and exits the body relatively quickly. The Company intends
to integrate PDT with its understanding of temporal neuroendocrine regulation
to try to improve the anti-cancer effect of PDT. The Company is in the process
of identifying a lead photosensitizer for clinical study in its PDT program.
Ergo has licensed from The Rowland Institute for Science the rights to patents
covering these phototherapeutic dyes.
 
COMMERCIALIZATION STRATEGY
 
  The Company's commercialization strategy includes the formation of marketing
alliances with major pharmaceutical companies to market the Company's
products. The Company also plans to establish long-term
 
                                      29
<PAGE>
 
manufacturing agreements for its product supply. The Company currently retains
all marketing rights to its drug candidates.
 
 Marketing
 
  The Company intends to form strategic alliances with large pharmaceutical
companies to market the Company's product candidates internationally and to
the managed care and the primary care physician markets in the United States.
In addition, the Company also intends to build, over time, a direct sales
force to market to the managed care, endocrinologist and diabetologist markets
in the United States. To date, the Company has internally funded the clinical
development of ERGOSET for Type II diabetes into advanced clinical trials
before seeking collaborative marketing arrangements. The Company is currently
seeking a marketing partner for ERGOSET for Type II diabetes. The Company
intends to retain co-promotion and marketing rights to its product candidates
in the United States. See "Risk Factors--Limited Sales and Marketing
Experience; Dependence on Future Collaborators."
 
 Manufacturing
 
  Ergo does not operate and does not plan to operate manufacturing facilities
for the production of either bulk chemicals or the pharmaceutical dosage forms
for its product candidates. Instead, it plans to establish long-term supply
contracts for the supply of its pharmaceuticals. The Company has agreed to buy
from Geneva, and Geneva has agreed to supply, all of the Company's United
States requirements for the final dosage form of ERGOSET for the treatment of
Type II diabetes and obesity. The supply agreement between Geneva and the
Company (the "Geneva Agreement") will terminate December 31, 2009. Geneva has
paid the Company various amounts and agreed to pay the Company additional
amounts upon the achievement of certain milestones. The Company is required to
carry liability insurance in the amount of at least $1,000,000 per occurrence
and $3,000,000 in the aggregate for product liabilities. Geneva may terminate
the Geneva Agreement in various circumstances, including if FDA does not
accept the Company's first filing of an NDA within 18 months of its submission
or approve that NDA within three years of submission or if the Company's
requirements of ERGOSET do not exceed certain minimum levels during the two
years following FDA approval, if obtained. Geneva has a right of first option
to be the exclusive supplier of the Company's United States requirements for
new orally administered drug products on commercially competitive terms.
 
  If Geneva does not perform its obligations under the Geneva Agreement, the
Company may not be able to obtain supplies of ERGOSET. Even if the Company is
able to obtain ERGOSET from other suppliers, it may not be on the terms or in
the quantities that would be acceptable to the Company. The active ingredient
in ERGOSET is available from few suppliers in the world, and the manufacturing
process for the active ingredient is complex and lengthy. Accordingly, the
Company will encounter significant delays if it must obtain supplies from
manufacturers other than Geneva or otherwise experiences interruptions in its
supplies. See "Risk Factors--Manufacturing Uncertainties; Reliance on Third-
Party Suppliers."
 
PATENTS, PROPRIETARY RIGHTS AND LICENSES
   
  Ergo's ability to commercialize profitably any product candidates will
depend, in part, upon its or its licensors' ability to obtain patents, enforce
those patents, preserve trade secrets, and operate without infringing upon the
proprietary rights of third parties. The Company has rights to more than 40
issued or pending United States patents and patent applications and to
counterparts to many of those patents and patent applications in other
countries. In addition, the Company's patent portfolio for its current product
candidates is based on the timed administration of neurotransmitter modulating
drugs to address abnormalities of the neuroendocrine system. If similar
benefits could be achieved by using such drugs without timed administration,
the Company's patents and proprietary technology would not prevent that use,
and this would likely have a material adverse effect on the Company. The
Company has filed a patent application in the United States relating to a
fast-release formulation of ERGOSET. LSU has licensed its interest in more
than 35 of those patents and patent applications exclusively to the Company.
The Company is a co-owner of certain of those U.S. patent applications and one
U.S. patent. The Company's rights in certain patent applications, including
applications covering the treatment     
 
                                      30
<PAGE>
 
of immune dysfunction and cancer as well as certain enzyme inhibitors and
certain receptor antagonists, are not exclusive, but the Company is
negotiating with the co-owner of those rights for an exclusive license. There
can be no assurance that the patent applications licensed to or owned by the
Company will result in issued patents, that patent protection will be secured
for any particular technology the Company develops, that any patents that have
been or may be issued to the Company or its licensors will be valid or
enforceable, or that any patents will provide meaningful protection to the
Company. See "Risk Factors--Uncertainty of Protection for Patents and
Proprietary Technology."
   
  In general, the United States patents and patent applications licensed to or
owned by the Company are method-of-use patents (as opposed to composition-of-
matter patents) that cover the timed use of certain compounds to treat
specified conditions. The U.S. patents for bromocriptine, the active
ingredient in ERGOSET, have expired, and composition-of-matter protection is
not available for bromocriptine. Bromocriptine is currently sold in the United
States and other markets for several uses other than the treatment of Type II
diabetes. Even in jurisdictions where the timed use of bromocriptine for Type
II diabetes may be covered by the claims of a use patent licensed to the
Company, off-label sales might occur, especially if another company markets
bromocriptine at a price that is less than the price of ERGOSET, thereby
potentially reducing the sales of ERGOSET.     
 
  The patent positions of biotechnology and pharmaceutical companies,
including Ergo, are highly uncertain and involve complex legal and factual
questions. There can be no assurance that patents will issue from the patent
applications filed by the Company or its licensors or that the scope of any
claims granted in any patent will provide proprietary protection or a
competitive advantage to the Company. There can be no assurance that the
validity or enforceability of patents issued or licensed to the Company will
not be challenged by others or that, if challenged, a court will find the
patents to be valid and enforceable. In addition, there can be no assurance
that competitors will not be able to circumvent any patents issued or licensed
to the Company. In the United States, patent applications are maintained in
secrecy until patents issue, and publications in the scientific and patent
literature lag behind actual discoveries. As a result, the Company cannot be
certain that its scientists were the first to make inventions covered by its
patents and patent applications. If a third party has also filed a patent
application for the Company's inventions, the Company may have to participate
in interference proceedings declared by the United States Patent and Trademark
Office to determine priority of invention. Moreover, patent interference
proceedings would be lengthy and expensive, even if the outcome is favorable
to the Company. While no patent that could be potentially infringed by
manufacture, use or sale of the Company's product candidates in the fields of
Type II diabetes and obesity has come to the attention of the Company, the
Company's product candidates are still in the development stage, and neither
their formulations (other than the active ingredient) nor their method of
manufacture have been finalized.
   
  There can be no assurance that the manufacture, use or sale of the Company's
product candidates will not infringe patent rights of others. The Company may
be unable to avoid infringement of those patents and may have to seek a
license, defend an infringement action, or challenge the validity of the
patents in court. There can be no assurance that a license will be available
to the Company, if at all, upon terms and conditions acceptable to the Company
or that the Company will prevail in any patent litigation. Patent litigation
is costly and time consuming, and there can be no assurance that the Company
will have sufficient resources to pursue such litigation. If the Company does
not obtain a license under such patents, is found liable for infringement, or
is not able to have them declared invalid, the Company may be liable for
significant money damages, may encounter significant delays in bringing
products to market, or may be precluded from participating in the manufacture,
use or sale of products or methods of treatment covered by such patents. There
can be no assurance that the Company has identified United States and foreign
patents that pose a risk of infringement.     
          
  The Company recently began a small study of two drugs in the treatment of
breast cancer. The Company is aware of two issued patents, owned by a third
party, some of the claims of which relate to one of the drugs being tested in
the breast cancer study. The Company believes that the relevant claims are
either invalid or not infringed by the Company's product candidate and method
of treatment. If it is determined that any of such relevant claims are
infringed by the Company's product candidate and not invalid, the Company may
have to seek a license, defend an infringement action, or challenge the
validity of such patents in court. There can be no     
 
                                      31
<PAGE>
 
   
assurance that a license will be available to the Company, that the terms and
conditions of any such license would be acceptable to the Company or that the
Company will prevail in any patent litigation. If the Company does not obtain
a license, is found liable for infringement, or is not able to have the
relevant claims declared invalid, then the Company may be liable for
significant money damages, may encounter significant delays, or may be
precluded from participating in the manufacture, use or sale of products or
methods of treatment covered by such patents.     
 
  Ergo also relies on trade secrets and other unpatented proprietary
information in its product development activities. To the extent the Company
relies on trade secrets and unpatented know-how to maintain its competitive
technological position, there can be no assurance that others may not
independently develop the same or similar technologies. The Company seeks to
protect trade secrets and proprietary knowledge, in part through
confidentiality agreements with its employees, consultants, advisors and
collaborators. Nevertheless, these agreements may not effectively prevent
disclosure of the Company's confidential information and may not provide the
Company with an adequate remedy in the event of unauthorized disclosure of
such information. If the Company's employees, scientific consultants or
collaborators develop inventions or processes independently that may be
applicable to the Company's product candidates, disputes may arise about
ownership of proprietary rights to those inventions and processes. Such
inventions and processes will not necessarily become the Company's property,
but may remain the property of those persons or their employers. Protracted
and costly litigation could be necessary to enforce and determine the scope of
the Company's proprietary rights. Failure to obtain or maintain patent and
trade secret protection, for any reason, would have a material adverse effect
on the Company. See "Risk Factors--Uncertainty of Protection for Patents and
Proprietary Technology."
 
  The Company engages in collaborations, sponsored research agreements, and
other arrangements, such as the LSU Agreement, with academic researchers and
institutions that have received and may receive funding from United States
government agencies. As a result of these arrangements, the U.S. government or
certain third parties may have rights in certain inventions developed during
the course of the performance of such collaborations and agreements as
required by law or such agreements.
 
  Several bills affecting patent rights have been introduced in the United
States Congress. These bills address various aspects of patent law, including
publication, patent term, re-examination, subject matter and enforceability.
It is not certain whether any of these bills will be enacted into law or what
form new laws may take. Accordingly, the effect of legislative change on the
Company's intellectual property estate is uncertain.
 
LSU AGREEMENT
 
  The Company's rights to ERGOSET and its other technologies derive primarily
from a license from LSU for certain patents and patent applications. The
Company is a co-owner of certain of these patents and patent applications.
Under an agreement originally signed in 1990 (as amended, the "LSU
Agreement"), LSU granted to Ergo an exclusive license to its rights under
certain patents and patent applications. The LSU Agreement will terminate upon
expiration of all licensed patents thereunder unless terminated earlier by LSU
or the Company in accordance with terms of the LSU Agreement. In the LSU
Agreement, the Company agreed to commercialize ERGOSET in all countries where
commercialization is reasonably justified economically. The Company is
responsible for prosecuting and maintaining the patents and patent
applications licensed from LSU and for obtaining governmental approval of any
product, process, or method covered thereby in those countries (for example,
FDA approval in the United States). The Company's policy is to file foreign
counterparts to its licensed patents in countries with significant
pharmaceutical markets where such protection is obtainable. The Company has a
right of first negotiation for new technologies that LSU develops relating to
the licensed technologies. There can be no assurance that the Company will
successfully obtain rights to any such new technologies. The LSU Agreement
requires the Company to make specified fixed payments to LSU and pay LSU
royalties at varying rates on its product sales covered by the licensed
patents. In December 1996, the Company is obligated to issue 18,750 shares of
Common Stock to LSU pursuant to the LSU Agreement. The LSU Agreement also
requires the Company to maintain customary general liability insurance and
customary product liability insurance for all countries in which it sells
products licensed under the LSU Agreement. LSU may terminate the LSU
 
                                      32
<PAGE>
 
Agreement if Ergo breaches the LSU Agreement and fails to cure the breach
within 45 days (for breach of payment obligations) or 90 days (for other
breaches) after notice of the breach from LSU. If the LSU Agreement is
terminated for any reason, the Company would no longer possess the rights
necessary to commercialize ERGOSET and certain other technologies relating to
the timed administration of neurotransmitter modulating drugs. This would have
a material adverse effect on the Company. See "Risk Factors--Uncertainty of
Protection for Patents and Proprietary Technology."
 
COMPETITION
 
  ERGOSET, if it is approved, will compete against existing therapies for Type
II diabetes such as insulin and oral hypoglycemic agents. FDA recently
approved two other drugs for treatment of Type II diabetes. Both of the drugs
have methods of action that are different from sulfonylureas and are intended
to address the hyperglycemia associated with diabetes. Bristol-Myers Squibb
Co. recently obtained FDA approval for and launched Glucophage (metformin) in
the United States for the treatment of Type II diabetes. Glucophage appears to
be gaining market acceptance rapidly as a new therapy. Metformin has been used
as an adjunct to oral hypoglycemic agents and in monotherapy to improve
glycemic control in diabetic patients without increasing serum insulin levels.
Bayer Pharmaceuticals recently obtained FDA approval in the United States for
a drug called Acarbose for the treatment of Type II diabetes. Acarbose is used
to reduce blood glucose by blocking the digestion of carbohydrates in the
stomach and intestine, thereby delaying or reducing the absorption of glucose
into the bloodstream.
 
  The active ingredient in ERGOSET is approved by FDA for indications other
than Type II diabetes. Physicians may choose to prescribe other drugs
containing this active ingredient for off-label use to try to achieve the same
effects as ERGOSET. Substitution of other forms of the active ingredient may
have a material adverse effect on the market for ERGOSET. This risk could be
increased if current regulations prohibiting off-label marketing are changed.
See "Business--Patents, Proprietary Rights and Licenses" and "Business--
Government Regulation." There can be no assurance that the Company's product
candidates, if commercialized, will be accepted and prescribed by healthcare
professionals.
 
  Ergo competes with biotechnology and established pharmaceutical companies in
all of its product development programs. Academic institutions, governmental
agencies, and other public and private research organizations also conduct
research, seek patent protection, and establish collaborative arrangements
with commercial entities for product development and marketing. Products
resulting from these activities may compete directly with any that the Company
develops. These companies and institutions also compete with the Company in
recruiting and retaining highly qualified scientific personnel. Many
competitors and potential competitors have substantially greater scientific
research and product development capabilities, as well as greater financial,
marketing and human resources, than the Company.
 
  Many other entities, including large pharmaceutical companies and
institutions, are developing therapeutic products that may compete with Ergo's
product candidates in the treatment of Type II diabetes, obesity, immune-
related diseases and cancer. Several different approaches to treating Type II
diabetes are being tested in United States clinical trials, including new oral
hypoglycemic agents that stimulate insulin production and new medicines that
stimulate glucose uptake in peripheral tissue. Other drugs are being developed
that may limit or delay the damage that diabetes causes to organs such as the
eyes and kidneys. Some of these products may be at a more advanced stage of
development than the Company's products.
 
  Competition for treatments for Type II diabetes is very intense. The Company
expects that competition among products approved for sale will be based on,
among other things, product safety, efficacy, ease of use, effect on co-morbid
conditions, availability, price, marketing and distribution. Even if ERGOSET
is approved by FDA for sale as a new treatment for Type II diabetes, there can
be no assurance that it will be able to compete successfully against other
products. See "Business--ERGOSET for Type II Diabetes--Phase II Clinical Trial
Results", "Business--ERGOSET for Type II Diabetes--Phase III Clinical Trial
Results," and "Risk Factors--Uncertainties Related to Phase III Clinical Trial
Results of ERGOSET."

GOVERNMENT REGULATION
   
  Ergo's research and development activities, preclinical studies and clinical
trials, and ultimately the manufacturing, marketing and labeling of its
products, if approved, are subject to extensive regulation by FDA and other
regulatory authorities in the United States. These activities are also
regulated in other countries where the Company intends to test and market its
products. The United States Federal Food, Drug, and Cosmetic Act and the
regulations promulgated thereunder and other federal and state statutes and
regulations govern, among other things, the testing, manufacture, safety,
efficacy, labeling, storage, record keeping, approval, advertising and
promotion of the Company's products. Preclinical study and clinical trial
requirements and the regulatory approval process take years and require the
expenditure of substantial resources. Additional government regulation may be
established that could prevent or delay regulatory approval of the Company's
product candidates. Delays or rejections in obtaining regulatory approvals
would adversely affect the Company's ability to commercialize any product
candidates the Company develops and the Company's ability to receive product
revenues or royalties. If regulatory approval of a product candidate is
granted, the approval may include significant limitations on the indicated
uses for which the product may be marketed.     
   
  FDA and other regulatory authorities require that the safety and efficacy of
the Company's therapeutic product candidates must be established by at least
two adequate and well-controlled Phase III clinical trials. If the results of
Phase III clinical trials do not establish the safety and efficacy of the
Company's product candidates to the satisfaction of FDA and other regulatory
authorities, the Company will not receive the approvals necessary to market
its product candidates, which would have a material adverse effect on the
Company.     
 
  The steps required before a pharmaceutical agent may be marketed in the
United States include (a) preclinical laboratory, in vivo, and formulation
studies, (b) the submission to FDA of an Investigational New Drug application
("IND"), which must become effective before human clinical trials may
commence, (c) adequate and well-controlled human clinical trials to establish
the safety and efficacy of the drug, (d) the submission of an NDA to FDA, and
(e) FDA approval of the NDA, including approval of all product labeling and
advertising.
 
  Preclinical tests include laboratory evaluation of product chemistry,
formulation and stability, as well as animal studies to assess the potential
safety and efficacy of each product. Preclinical safety tests must be
conducted by laboratories that comply with FDA regulations regarding Good
Laboratory Practices. The results of the preclinical tests are submitted to
FDA as part of an IND and are reviewed by FDA before the commencement of human
clinical trials. Unless FDA objects to an IND, the IND will become effective
30 days following its receipt by FDA. There can be no assurance that
submission of an IND will result in FDA authorization to commence clinical
trials or that the lack of an objection means that FDA will ultimately approve
an NDA.
 
  Clinical trials involve the administration of the investigational new drug
to humans under the supervision of a qualified principal investigator.
Clinical trials must be conducted in accordance with Good Clinical Practices
under protocols that detail the objectives of the study, the parameters to be
used to monitor safety, and efficacy criteria to be evaluated. Each protocol
must be submitted to FDA as a part of the IND. Also, each clinical trial must
be approved and conducted under the auspices of an Institutional Review Board,
which will consider, among other things, ethical factors, the safety of human
subjects, and the possible liability of the institution conducting the
clinical trials.
 
  Clinical trials are typically conducted in three sequential phases, but the
phases may overlap, as is the case with ERGOSET trials. Phase I clinical
trials involve the initial introduction of the drug into healthy human
subjects. In Phase I clinical trials, the drug is tested for safety (adverse
effects), dosage tolerance, metabolism, distribution, excretion, and
pharmacodynamics (clinical pharmacology). Phase II clinical trials are
conducted in a limited patient population to gather evidence about the
efficacy of the drug for specific, targeted indications; to determine dosage
tolerance and optimal dosage; and to identify possible adverse effects and
safety risks. When a compound has shown evidence of efficacy and an acceptable
safety profile in Phase II evaluations, Phase III
 
                                      34
<PAGE>
 
clinical trials are undertaken to evaluate clinical efficacy and to test for
safety in an expanded patient population at geographically dispersed clinical
trial sites. There can be no assurance that any of the Company's clinical
trials will be completed successfully or within any specified time period. The
Company or FDA may suspend clinical trials at any time.
 
  The Company designed the protocols for its Phase III clinical trials based
on its analysis of its research, including various parts of its Phase II
clinical trials. Although copies of its Phase III clinical trial protocols
were submitted to FDA, there can be no assurance that FDA will not disagree
with the design of the Phase III clinical trial protocols. In addition, FDA
inspects and reviews clinical trial sites, informed consent forms, data from
the clinical trial sites including case report forms and record keeping
procedures, and the performance of the protocols by clinical trial personnel
to determine compliance with Good Clinical Practice. FDA also seeks to
determine whether there was bias in the conduct of clinical trials. The
conduct of clinical trials in general and the performance of the Phase III
clinical trial protocols is complex and difficult. There can be no assurance
that the design or the performance of the Phase III clinical trial protocols
will be acceptable to FDA.
 
  The results of preclinical studies and clinical trials, if successful, are
submitted in an NDA to seek FDA approval to market and commercialize the drug
product for a specified use. The testing and approval process require
substantial time and effort, and there can be no assurance that any approval
will be granted for any product or that approval will be granted according to
any schedule. FDA may deny an NDA if it believes that applicable regulatory
criteria are not satisfied. FDA may also require additional testing for safety
and efficacy of the drug. Moreover, if regulatory approval of a drug product
is granted, the approval will be limited to specific indications. There can be
no assurance that any of the Company's product candidates will receive
regulatory approvals for commercialization. See "Risk Factors--Government
Regulation; No Assurances of Regulatory Approval."
   
  FDA has implemented an accelerated review process for pharmaceutical agents
that treat serious or life threatening diseases and conditions, subject to
payment of user fees. When appropriate, the Company intends to pursue
opportunities for accelerated review of its products. The Company cannot
predict the ultimate effect of this review process on the timing or likelihood
of FDA review of any of its product candidates. FDA may determine that product
candidates are not eligible for or will not receive expedited review, whether
or not FDA has previously indicated that such product candidates may be
eligible for expedited review.     
 
  Even if regulatory approvals for the Company's product candidates are
obtained, the Company, its products, and the facilities manufacturing the
Company's products are subject to continual review and periodic inspection.
FDA will require post-marketing reporting to monitor the safety of the
Company's products. Each United States drug manufacturing establishment must
be registered with FDA. Domestic manufacturing establishments are subject to
biennial inspections by FDA and must comply with FDA's current Good
Manufacturing Practices. To supply drug products for use in the United States,
foreign manufacturing establishments must comply with FDA's Good Manufacturing
Practices and are subject to periodic inspection by FDA or by regulatory
authorities in those countries under reciprocal agreements with FDA. In
complying with Good Manufacturing Standards, manufacturers must expend funds,
time and effort in the area of production and quality control to ensure full
technical compliance. The Company does not have any drug manufacturing
capability and must rely on outside firms for this capability. See "Business--
Commercialization Strategy--Manufacturing." FDA stringently applies regulatory
standards for manufacturing. Discovery of previously unknown problems with
respect to a product, manufacturer or facility may result in restrictions on
the product, manufacturer or facility, including warning letters, suspensions
of regulatory approvals, operating restrictions, delays in obtaining new
product approvals, withdrawal of the product from the market, product recalls,
fines, injunctions, and criminal prosecution.
 
  A bill proposing comprehensive reform of FDA regulations has been introduced
in the United States Senate. This bill addresses many facets of FDA
regulations, including requirements for NDA approval, requirements for
supplemental approval and export regulations. A counterpart bill has been
introduced into the United States House of Representatives that includes
provisions concerning off-label information dissemination. It is not
 
                                      35
<PAGE>
 
certain whether any such legislation will be enacted into law, what form any
law will take, or what effect any new law would have on the Company.
 
  Before Ergo's drug products can be marketed outside of the United States,
they are subject to regulatory approval similar to FDA requirements in the
United States, although the requirements governing the conduct of clinical
trials, product licensing, pricing, and reimbursement vary widely from country
to country. No action can be taken to market any drug product in a country
until an appropriate application has been approved by the regulatory
authorities in that country. FDA approval does not assure approval by other
regulatory authorities. The current approval process varies from country to
country, and the time spent in gaining approval varies from that required for
FDA approval. In some countries, the sale price of a drug product must also be
approved. The pricing review period often begins after market approval is
granted. Even if a foreign regulatory authority approves any of the Company's
product candidates, no assurance can be given that it will approve
satisfactory prices for the products.
 
  The active ingredient in ERGOSET has been approved by FDA for use in humans
for more than 15 years for several indications, including treating Parkinson's
disease, acromegaly, and hyperprolactinemia. One company marketing
bromocriptine in the United States recently agreed voluntarily to remove the
indication of suppressing lactation in postpartum females after FDA initiated
action to withdraw the drug's approval for this indication. FDA had noted that
the benefit of using the drug for this indication was marginal and did not
outweigh the risks in this particular patient population including
hypertension, seizures, and cerebrovascular incidents. FDA has not taken
action with respect to the other approved indications, and bromocriptine
remains on the market for the treatment of Parkinson's disease, acromegaly,
and hyperprolactinemia. The Company's clinical trials exclude postpartum
females, and the data from the Company's completed Phase II and Phase III
clinical trials lead the Company to believe that ERGOSET does not present the
same health risks to its proposed patient population.
 
  Ergo's research and development involves the controlled use of hazardous
materials, chemicals, viruses, and various radioactive compounds. Although the
Company believes that its procedures for handling and disposing of those
materials comply with state and federal regulations, the risk of accidental
contamination or injury from these materials cannot be eliminated. If such an
accident occurs, the Company could be held liable for resulting damages, which
could be material to the Company's financial condition and business. The
Company will include an environmental assessment in the NDA in accordance with
FDA regulations. The Company is also subject to numerous environmental, health
and workplace safety laws and regulations, including those governing
laboratory procedures, exposure to blood-borne pathogens, and the handling of
biohazardous materials. Additional federal, state and local laws and
regulations affecting the Company may be adopted in the future. Any violation
of, and the cost of compliance with, these laws and regulations could
materially and adversely affect the Company.
 
HUMAN RESOURCES
 
  As of July 1, 1996, the Company had 65 full-time employees, including 11
persons with Ph.D. degrees. Forty-nine of Ergo's employees are engaged in
research and development activities. None of the Company's employees is
covered by a collective bargaining agreement, and the Company believes its
employee relations are good.
 
FACILITIES
 
  Ergo leases approximately 36,000 square feet in three buildings in the
Charlestown Navy Yard, Charlestown, Massachusetts, of which approximately
26,000 square feet are used for research and development functions and
approximately 10,000 square feet are used for administrative functions. The
Company's principal offices are leased through 1997, with a renewal option for
one five-year term. Space in a nearby building is leased until August 1997,
and space in another building is leased through April 1998, with two five-year
renewal options. The Company believes that its facilities are adequate for its
current needs. The Company believes it can obtain additional space on
commercially reasonable terms.
 
LEGAL PROCEEDINGS AND INSURANCE
 
  The Company is not a party to any material legal proceedings.
 
  The Company maintains product liability coverage for claims arising from the
use of ERGOSET and its technologies in clinical trials. See "Risk Factors--
Potential Product Liability; Availability of Insurance."

  Executive officers are generally elected annually by the Board of Directors
to serve, subject to the discretion of the Board of Directors, until their
successors are appointed. Manuel Cincotta, Jr., and Dr. Anthony H. Cincotta
are brothers. A brief biography of each director and executive officer
follows.
 
  Manuel Cincotta, Jr., has been Chairman of the Board, Treasurer and
Secretary of the Company since January 1990. From January 1990 until November
1995, Mr. Cincotta was Chief Executive Officer of the Company. For health
reasons, Mr. Cincotta retired as Chief Executive Officer in November 1995.
From 1969 until 1992, Mr. Cincotta was employed as a scientist by the
Department of the Navy's Research and Technology Branch of the Naval
Underwater Systems Center, most recently as a chief scientist and senior
project engineer. Mr. Cincotta received his B.S. and M.S. in chemical
engineering from the Lowell Technological Institute.
 
  J. Warren Huff has been President and Chief Executive Officer of the Company
since November 1995. Mr. Huff joined the Company as its Executive Vice
President, Commercial Development and Finance, in February 1993. He became
President and Chief Operating Officer of the Company in January 1994, and he
has served as a director of the Company since January 1994. From 1979 until
1993, Mr. Huff was an attorney at Johnson & Gibbs, P.C., a law firm in Dallas,
Texas, where most recently he was chairman of the firm's corporate/securities
department. Mr. Huff represented companies in the medical science,

ELECTION AND COMMITTEES OF DIRECTORS
 
  The Board of Directors is divided into three classes. The directors of each
class are elected for three-year terms, with the terms of the three classes
staggered so that directors from a single class are elected at each annual
meeting of stockholders. Stephen A. Duzan and J. Warren Huff are Class I
directors whose terms of office expire at the annual meeting of stockholders
in 1999; Ray L. Hunt and Thomas F. McWilliams are Class II directors whose
terms of office expire at the annual meeting of stockholders in 1997; and
Anthony H. Cincotta, Ph.D., Manuel Cincotta, Jr., and Albert H. Meier, Ph.D.,
are Class III directors whose terms of office expire at the annual meeting of
stockholders in 1998. The Company intends to add two additional independent
directors to its Board of Directors.
 
  The Board of Directors has three standing committees: the Audit Committee,
the Compensation Committee, and the Nominating Committee. The Audit Committee
reviews the results and scope of the annual audit and other services provided
by the Company's independent public accountants. The Compensation Committee of
the Board of Directors determines salaries and incentive compensation for
officers of the Company. In addition, the Board of Directors has designated
the Compensation Committee as the administrator of the Company's Amended and
Restated 1995 Long-Term Incentive Plan (the "Incentive Plan"). See
"Management--Employee Benefit Plans--Incentive Plan." The Nominating Committee
identifies and recruits candidates to serve as directors of the Company for
recommendation to the full Board of Directors.
 
COMPENSATION OF DIRECTORS
 
  Directors of the Company do not receive cash compensation for their services
as directors. The Company reimburses them for the expenses incurred in
attending meetings of the Board of Directors and its committees. On November
15, 1994, the Company granted Mr. Duzan a nonqualified option to purchase
7,500 shares of Common Stock at an exercise price of $0.80 per share in
consideration for his service as a director. This option becomes exercisable
in three equal amounts on the date of grant and on each of the first two
anniversaries of the date of grant. The option expires in July 2004. On
October 6, 1995, the Company granted Mr. Duzan a nonqualified option to
purchase 17,500 shares of Common Stock at an exercise price of $6.71 per share
in consideration for his service as a director. This option becomes
exercisable in four equal amounts on each of the first four anniversaries of
the date of grant, or, if earlier, upon a change in control of the Company.
The option expires ten years from the date of grant.
 
  In June 1996, Ergo's shareholders approved a Stock Option Plan for Non-
Employee Directors (the "Director Stock Plan"). The Director Stock Plan
provides for an initial grant of a stock option for 10,000 shares of Common
Stock to each non-employee director upon first being elected or appointed to
serve on the Board of Directors. Each non-employee director serving when the
Director Stock Plan was approved (other than Mr. Duzan) was granted a stock
option for 10,000 shares of Common Stock with a deemed grant date of May 15,
1996. On the second anniversary of the initial grant date, those non-employee
directors will be granted a second nonqualified stock option for 10,000 shares
of Common Stock if they are still directors on that date. On October 6, 1999,
which is the date Mr. Duzan's existing options are scheduled to become
exercisable, Mr. Duzan will be granted a stock option to purchase 10,000
shares of Common Stock if he is still a director. The total number of shares
of Common Stock authorized for issuance under the Director Stock Plan is
200,000. Each option under the Director Stock Plan has an exercise price equal
to the fair market value of the Common Stock on the grant date. These options
will become exercisable in equal increments on the first and second
anniversary of their date of grant and will expire ten years after the grant
date if not exercised. If a change in control of the Company occurs, all stock
options granted under the Director Stock Plan will become fully exercisable.
 
 
                                      40

  In October 1995, the Company entered into a consulting agreement with Dr.
Albert Meier in which the Company agreed to pay Dr. Meier $100,000 per year
for at least 20 hours of consulting services per week through October 1998.
Dr. Meier agreed that all work product discovered, created or developed by
him, alone or with others, will belong to the Company. Dr. Meier also agreed
to maintain the confidentiality of the Company's proprietary information. In
addition, Dr. Meier agreed not to compete with the Company for two years
following the end of his consulting services; however, the Company is required
to pay Dr. Meier $50,000 within 10 days after the end of his consulting
services and $100,000 on the first anniversary of termination of his
consulting services to maintain the noncompetition obligation. The Company may
terminate the consulting arrangement at any time. However, if the termination
is without cause, the Company must pay Dr. Meier the lesser of $100,000 or the
amount of fees he would have received under the remaining term of the
agreement.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  As permitted under Delaware law, the Company's Certificate of Incorporation
provides that no director of the Company will be personally liable to the
Company or any of its stockholders for monetary damages arising from the
director's breach of fiduciary duty as a director. This limitation does not
apply with respect to any action in which the director would be liable under
the Delaware General Corporation Law for authorizing illegal dividends, stock
repurchases or redemptions. This limitation also does not apply with respect
to any liability in which the director (i) breached his duty of loyalty to the
Company; (ii) did not act in good faith or, in failing to act, did not act in
good faith; (iii) acted in a manner involving intentional misconduct or a
knowing violation of law or, in failing to act, acted in a manner involving
intentional misconduct or a knowing violation of law; or (iv) derived an
improper personal benefit.
 
  The Company has entered into indemnification agreements with each of its
directors and executive officers, agreeing to indemnify the director or
officer to the fullest extent permitted by law, and to advance expenses, if
the director or officer becomes a party to or witness or other participant in
any threatened, pending or completed action, suit or proceeding (a "Claim") by
reason of any occurrence related to the fact that the person is or was a
director, officer, employee, agent or fiduciary of the Company or a subsidiary
of the Company or another entity at the Company's request (an "Indemnifiable
Event"), unless a reviewing party (either outside counsel or a committee
appointed by the Board of Directors) determines that the person would not be
entitled to indemnification under applicable law. In addition, if a change in
control or a potential change in control of the Company occurs and if the
person indemnified so requests, the Company will establish a trust for the
benefit of the indemnitee and fund the trust in an amount sufficient to
satisfy all expenses reasonably anticipated at the time of the request to be
incurred in connection with any Claim relating to an Indemnifiable Event. The
reviewing party will determine the amount deposited in the trust. An
indemnitee's rights under the indemnification agreement are not exclusive of
any other rights under the Company's Certificate of Incorporation or Bylaws or
applicable law.
 
  The Company believes that these provisions and agreements will assist the
Company in attracting and retaining qualified individuals to serve as
directors and officers.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The members of the Compensation Committee are Stephen A. Duzan, Ray L. Hunt,
and Thomas F. McWilliams. None of them is or has been an employee of the
Company. No executive officer of the Company serves as a member of the board
of directors or compensation committee of any entity that has one or more
executive officers serving as a member of the Company's Board of Directors or
Compensation Committee. Messrs. Hunt and McWilliams, or their affiliates, have
acquired capital stock of the Company and loaned funds to the Company. See
"Certain Transactions."

(1) Options granted are nonqualified options under the Incentive Plan that
    become exercisable in four equal amounts on each of the first four
    anniversaries of the date of grant, subject to earlier termination in
    accordance with the option agreements. Exercisability of options will
    accelerate upon a change in control of the Company, termination of
    employment by the Company without cause, or termination of employment by
    the optionee with good reason. See "Management--Employee Benefit Plans--
    Incentive Plan."
(2) Amounts represent hypothetical gains that could be achieved for the
    options if they are exercised at the end of the option term. Those gains
    are based on assumed rates of stock price appreciation of 0%, 5% and 10%
    compounded annually from the date the option was granted through the
    expiration date.

 Employment Contracts
 
  The Company has entered into employment agreements with J. Warren Huff,
Manuel Cincotta, Jr., Dr. Ronald H. Abrahams, Thomas N. Thurman, Alan T.
Barber, and Dr. Anthony H. Cincotta. The agreements provide for the payment of
base salary amounts of $225,000 for Mr. Huff, $225,000 for Manuel Cincotta,
Jr., $200,000 for Dr. Abrahams, $175,000 for Mr. Thurman, $135,000 for Mr.
Barber, and $200,000 for Dr. Cincotta. The Compensation Committee may increase
the base amounts at its discretion. The Company also agreed to provide Manuel
Cincotta, Jr., with use of a Company automobile and to pay premiums on term
life and disability insurance policies on Mr. Cincotta with a death benefit of
at least $2,500,000 for his beneficiary. The Company has also agreed to
reimburse Mr. Cincotta for taxes he incurs because of those benefits and this
reimbursement. The employment agreements expire in October 1998.
 
  Either party may terminate employment with or without cause on five days
written notice. Under the employment agreements, an executive officer is
entitled to receive a lump sum payment equal to his base salary if his
employment is terminated (i) by the Company for any reason other than
disability or for cause, or (ii) by the executive officer for good reason.
However, if either termination described in the preceding sentence follows a
change in control of the Company, the executive officer is entitled to receive
a lump sum payment equal to two times the sum of his base salary and budgeted
bonus. After any such termination, or any termination resulting from the
executive officer's disability or death, the executive officer or his family
is entitled to continue participation in any benefit plan maintained by the
Company until the end of the employment term stated in the employment
agreement.
 
  Each executive officer has agreed that all work product discovered, created
or developed by him, alone or with others, will belong to the Company. Each
executive officer has agreed to maintain the confidentiality of the Company's
proprietary information. In addition, Dr. Cincotta has agreed not to compete
with the Company for two years following the end of his employment, and each
other executive officer has agreed not to compete with the Company for three
years following the end of his employment; however, the Company is required to
pay to the executive officer an amount equal to 50% of his base salary within
10 days after termination and 100% of his base salary on the first and (other
than Dr. Cincotta) second anniversaries following termination of his
employment to maintain the non-competition obligation.
 
EMPLOYEE BENEFIT PLANS
 
 Incentive Plan
 
  The Company may grant officers, directors, employees and consultants awards
with respect to shares of Common Stock under the Company's Amended and
Restated 1995 Long-Term Incentive Plan (the "Incentive Plan"). The awards
under the Incentive Plan include both incentive and nonqualified stock
options, stock appreciation rights ("SARs") and restricted stock awards. The
number of shares of Common Stock that may be issued under the Incentive Plan
is 1,431,525 shares. As of March 31, 1996, the Company had granted options
under the Incentive Plan for 662,625 shares of Common Stock to officers,
directors, employees and consultants.
 
  The Compensation Committee (the "Committee") administers the Incentive Plan,
selects participants, and determines the type and size of awards, when awards
will be granted, and the terms of each award including exercise price, if any.
 
  An option is the right to purchase Common Stock at a specified exercise
price. The exercise price for incentive stock options must not be less than
the fair market value of the Common Stock on the date of grant. The Committee
determines at the time of grant when the option will become exercisable. At
the discretion of the Committee, holders may use shares of stock to pay the
exercise price, including shares issuable upon exercise of the option.
 
                                      44
<PAGE>
 
  An SAR may be awarded in connection with or separate from a stock option. An
SAR is the right to receive an amount in cash or stock equal to the excess of
the fair market value of a share of the Common Stock on the date of exercise
over the exercise price specified in the agreement governing the SAR (for SARs
not granted in connection with a stock option) or the exercise price of the
related stock option (for SARs granted in connection with a stock option). An
SAR granted in connection with a stock option will require the holder, upon
exercise, to surrender the related stock option or portion thereof relating to
the number of shares for which the SAR is exercised. The surrendered stock
option or portion will then cease to be exercisable. Such an SAR is
exercisable or transferable only to the extent that the related stock option
is exercisable or transferable. An SAR granted independently of a stock option
will be exercisable as the Committee determines. The Committee may limit the
amount payable upon exercise of any SAR.
 
  A restricted stock award is a grant of shares of Common Stock that is
nontransferable or subject to risk of forfeiture until specific conditions are
met. The restrictions will lapse in accordance with a schedule or other
conditions as the Committee determines. During the restriction period, the
holder of a restricted stock award may, in the Committee's discretion, have
certain rights as a stockholder, including the right to vote the stock subject
to the award or receive dividends on that stock. Restricted stock may also be
issued upon exercise or settlement of options or SARs.
 
  The Committee has discretion to determine whether an award under the
Incentive Plan should have change of control features. The Committee also has
discretion to vary the change of control features as it deems appropriate. The
following describes the change of control features that the Company generally
expects may apply to additional awards, if any such feature applies. An award
agreement under the Incentive Plan may provide that, upon a change of control
of the Company, (1) the holder of a stock option will be granted a
corresponding SAR, (2) all outstanding SARs and options will become
immediately and fully vested and exercisable in full, and (3) the restriction
period on any restricted stock award will be accelerated and the restrictions
will expire. Outstanding options under the Incentive Plan have the provision
described in the preceding clause (2). In general, a change in control of the
Company occurs in any of four situations: (1) a person other than the Company,
certain affiliated companies or benefit plans, or a company a majority of
which is owned directly or indirectly by the stockholders of the Company,
becomes the beneficial owner of 50% or more of the voting power of the
Company's outstanding voting securities; (2) a majority of the Board of
Directors is not comprised of the members of the Board of Directors at
September 15, 1995, and persons whose elections as directors were approved by
those directors or their approved successors; (3) the Company merges or
consolidates with another corporation or entity (whether the Company or the
other entity is the survivor), or the Company and the holders of the voting
securities of such other corporation or entity (or the stockholders of the
Company and such other corporation or entity) participate in a securities
exchange, other than a merger, consolidation or securities exchange in which
the Company's voting securities are converted into or continue to represent
securities having the majority of voting power in the surviving company; or
(4) the Company liquidates or sells all or substantially all of its assets,
except sales to any entity having substantially the same ownership as the
Company.
 
 Other Stock Options
 
  At various times since its formation, the Company granted options not under
the Incentive Plan for 100,000 shares to Manuel Cincotta, Jr., 75,000 shares
to Dr. Anthony H. Cincotta, 75,000 shares to Dr. Albert H. Meier, 144,725
shares to J. Warren Huff, 43,750 shares to Dr. Ronald H. Abrahams, 31,250
shares to Thomas N. Thurman, and 18,750 shares to Alan T. Barber, all at an
exercise price of $.80 per share. The options are fully exercisable other than
those granted to Dr. Abrahams, Mr. Thurman and Mr. Barber. The options for
Dr. Abrahams, Mr. Thurman and Mr. Barber were granted on March 31, 1994, June
21, 1994, and November 8, 1993, respectively, and become exercisable in equal
increments on each of the first three anniversaries of their dates of grant.
Each option expires at various times between December 31, 2002, and June 30,
2004. These options automatically become exercisable upon a change in control,
termination of the holder's employment with the Company by the Company without
cause, or termination of the holder's employment with the Company by the
holder for good reason.
 
                                      45
<PAGE>
 
  In connection with these options, the Company agreed to assist these
officers in paying all federal, state and local income tax liabilities with
respect to the Common Stock issued upon exercise of his options by
facilitating a sale of the Common Stock or arranging for the Company to
repurchase a portion of these shares issued.
 
                             CERTAIN TRANSACTIONS
 
  On September 10, 1992, CVC, Citi Growth Fund, L.P. ("Citi Growth"), and CVC
employees including Mr. McWilliams purchased $3,500,000 principal amount of
subordinated notes of the Company (the "Series A Notes") at face value. The
Series A Notes were convertible into shares of Series A Convertible Preferred
Stock of the Company. On October 12, 1993, CVC, Citi Growth, CVC employees
including Mr. McWilliams, Hunt Financial, and another entity purchased 20,940
shares of the Company's Series B Preferred Stock for $10,041,986. Concurrently
with the purchase, the purchasers of the Series A Notes converted the Series A
Notes into 8,826 shares of the Company's Series A Preferred Stock.
 
  On July 15, 1994, Hunt Financial purchased 6,255 shares of the Company's
Series C Preferred Stock for $2,999,647. Hunt Financial purchased an
additional 10,426 shares of Series C Preferred Stock on May 30, 1995, for
$4,999,892. With Hunt Financial's first purchase of the Series C Preferred
Stock, the Company issued to Hunt Financial for $.0004 per warrant, a warrant
to purchase 30,400 shares of the Company's Common Stock at $16.20 per share.
With Hunt Financial's second purchase, the Company issued to Hunt Financial
for $.0004 per warrant, warrants to purchase an additional 50,650 shares of
Common Stock at $16.20 per share. Before Hunt Financial's second purchase of
Series C Preferred Stock, Hunt Financial loaned the Company $1,000,000 on
February 3, 1995; $2,009,863 on March 10, 1995 ($1,009,863 of which the
Company used to repay the February 1995 loan); and $3,028,845 on April 13,
1995 ($2,028,845 of which the Company used to repay the March 1995 loan). The
Company used a portion of the proceeds of Hunt Financial's second purchase of
Series C Preferred Stock to repay the $3,067,846.57 principal and interest on
the April 1995 loan. The Company used the loans for working capital. The loans
bore interest at 1% over the prime rate and were unsecured.
 
  On September 1, 1995, CVC, Citi Growth, CVC employees including Mr.
McWilliams, Hunt Financial, and Lafayette Investment Company ("Lafayette"), a
company controlled by Mr. Hunt, entered into a loan agreement (the "Loan
Agreement") in which they agreed to lend the Company up to $6,000,000 at an
interest rate of 10% per annum. The Company borrowed $4,000,000 under the Loan
Agreement. Upon the closing of the Company's initial public offering in
December 1995, the principal and interest on the loan were converted into
Common Stock at $9.00 per share, resulting in 451,767 shares of Common Stock
being issued.
 
  In connection with this loan, the Company and the lenders agreed that the
shares of Series A, Series B and Series C Preferred Stock would convert to
Common Stock upon the closing of the initial public offering at a weighted
average conversion price of $6.41 per share of Common Stock. Before then, the
Series A, Series B and Series C Preferred Stock had conversion prices of
$16.90, $19.18, and $19.18 per share of Common Stock, respectively, but would
not have converted to Common Stock upon closing of the initial public
offering. Also, all warrants previously issued to Hunt Financial were
cancelled. In connection with the changes in conversion prices, the Company
recorded a preferred stock dividend in the amount of $7,123,536.

  The following table sets forth (i) the amount that each of CVC, Citi Growth,
Mr. McWilliams, Hunt Financial, and Lafayette had invested in Series A, Series
B and Series C Preferred Stock and loaned under the Loan Agreement, and (ii)

were converted:

  In addition, Ergo granted demand and piggyback registration rights to the
purchasers of Preferred Stock and to these lenders with respect to the Common
Stock issued upon conversion of the Series A, Series B and Series C Preferred
Stock or issued in payment of the loan at the closing of the intial public
offering. See "Description of Capital Stock--Registration Rights."
 
  In 1992, the Company agreed to purchase from Dr. Anthony Cincotta his
interest in patents and patent applications relating to the Company's
technology. Under the agreement, the Company was to pay Dr. Cincotta $200,000
each year for five years. The Company made one of those payments. In December
1995, the Company paid to Dr. Cincotta $800,000 in full satisfaction of those
obligations.
 
  The Company licenses certain patents and patent obligations from LSU that
relate to inventions of Drs. Anthony Cincotta and Albert Meier. LSU's bylaws
give inventors of LSU's patents the right to share in any royalties LSU
receives from those patents. In April 1995, the Company issued to each of Drs.
Cincotta and Meier 60,000 shares of Common Stock to acquire their inventors'
share of royalties attributable to the Company's license payments to LSU under
the LSU Agreement. The number of shares of Common Stock issued was negotiated
between Drs. Cincotta and Meier and the Company's Board of Directors. See
"Business--LSU Agreement."

share ("Preferred Stock").
 
COMMON STOCK
 
  The holders of Common Stock are entitled to one vote for each share held on
all matters submitted to a vote of common stockholders. Common Stock does not
have cumulative voting rights, which means that the holders of a majority of
the shares of Common Stock outstanding can elect all the directors and the
holders of the remaining shares will not be able to elect any directors. Each
share of Common Stock is entitled to participate equally in dividends, if, as
and when declared by the Company's Board of Directors, and in the distribution
of assets in the event of liquidation, subject in all cases to any prior
rights of outstanding shares of Preferred Stock. The Company has never paid
cash dividends on its Common Stock other than $166,910 of distributions made
in 1993 to stockholders when the Company was owned only by individuals and had
elected to be treated as an S corporation for federal income tax purposes. The
shares of Common Stock have no preemptive or conversion rights, redemption
rights, or sinking fund provisions. The outstanding shares of Common Stock
are, and the shares of Common Stock offered hereby upon issuance and sale will
be, duly authorized, validly issued, fully paid, and nonassessable.
 
PREFERRED STOCK
 
  The Company is authorized to issue 10,000,000 shares of Preferred Stock. The
Company's Board of Directors may establish, without stockholder approval, one
or more classes or series of Preferred Stock having the number of shares,
designations, relative voting rights, dividend rates, liquidation and other
rights, preferences, and limitations that the Board of Directors may
designate. The Company believes that this power to issue Preferred Stock will
provide flexibility in connection with possible corporate transactions. The
issuance of Preferred Stock, however, could adversely affect the voting power
of holders of Common Stock and restrict their
 
                                      49
<PAGE>
 
rights to receive payments upon liquidation of the Company. It could also have
the effect of delaying, deferring or preventing a change in control of the
Company. The Company does not currently plan to issue additional shares of
Preferred Stock. As of June 30, 1996, the Company's outstanding Preferred
Stock consisted of 6,903 shares of Series D Preferred Stock.
 
SERIES D PREFERRED STOCK
 
  The Company issued the 6,903 shares of Series D Preferred Stock on April 27,
1995. These shares will remain outstanding following the offering until they
are converted into Common Stock at the Company's option as described in
"Description of Capital Stock--Series D Preferred Stock--Conversion at the
Company's Option," or until they are automatically exchanged into subordinated
notes as described in "Description of Capital Stock--Series D Preferred
Stock--Automatic Exchange," if the Company does not exercise its conversion
option after the option becomes exercisable. The following description is a
summary of the Certificate of Amendment to the Certificate of Designation for
the Series D Preferred Stock, and it is qualified in its entirety by reference
to that document.
 
  Series D Preferred Stock ranks, with respect to dividend rights and
distribution of assets on liquidation, senior and prior to Common Stock and
junior to, or on parity with, as the case may be, any other stock of the
Company designated as senior to, or on parity with, as the case may be, Series
D Preferred Stock. Holders of Series D Preferred Stock will be entitled to
receive cumulative cash dividends at the rate of 6% per share per annum,
compounded annually, on the Stated Value thereof out of the funds legally
available therefor, if, as and when declared by the Company's Board of
Directors. The "Stated Value" per share of Series D Preferred Stock is $1,000
plus all accumulated and unpaid dividends thereon. Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Company, the holders
of Series D Preferred Stock then outstanding will be entitled to receive an
amount of cash equal to the Stated Value of Series D Preferred Stock after any
distribution is made on any senior securities and before any distribution is
made on any junior securities, including Common Stock. Except as required by
law, the holders of Series D Preferred Stock will have no voting rights. As
long as any shares of Series D Preferred Stock are outstanding, the Company
may not pay a dividend or other distribution on or repurchase Common Stock,
directly or indirectly, without first obtaining the affirmative vote or
written consent of the holders of a majority of the outstanding Series D
Preferred Stock, with certain exceptions. The terms of Series D Preferred
Stock may be amended with the consent of the holders of a majority of the
outstanding shares of Series D Preferred Stock.
 
  Conversion at the Company's Option. At the Company's option exercised by
written notice to the holders of Series D Preferred Stock at any time during
the 90-day period following the Company's receipt of FDA approval to market
its first product (a "Trigger Event"), if that approval is received, each
share of Series D Preferred Stock will be converted into the number of shares
of Common Stock that is determined by dividing the Stated Value then in effect
for each share by 95% of the Average Trading Price in effect at the time for
the Common Stock. The "Average Trading Price" means as of any date the average
of the following for the 15 trading days immediately preceding that date: (a)
if Common Stock is then listed or admitted to trading on any securities
exchange registered under the Securities Exchange Act of 1934, the closing
price per share of the Common Stock, regular way, on such day, or if no sale
takes place on that day, the average of the closing bid and asked prices on
that day, (b) if the Common Stock is not then listed or admitted to trading on
any such securities exchange, the last reported sale price per share of the
Common Stock on that day, or if no sale takes place on that day, the average
of the high bid and low asked prices as reported by a reputable quotation
source designated by the Company, or (c) if the stock is not then listed or
admitted to trading on any such securities exchange and no such reported sale
price or bid and asked prices are available, the average of the reported high
bid and low asked prices per share of the Common Stock on that day, or if
there shall be no bid and asked prices on that day, the average of the high
bid and low asked prices, as so reported, on the most recent day for which
prices have been so reported. However, if the Common Stock is not then listed
or admitted to trading on any such securities exchange, and no such reported
sale price or bid and asked prices are available or reported, the Average
Trading Price will mean the fair market value per share of Common Stock as the
Company's Board of Directors determines in good faith. The Company currently
intends to exercise its option to convert the Series D Preferred Stock into
Common Stock if a Trigger Event occurs.
 
                                      50

  Automatic Exchange. Effective upon the expiration of the 90-day period
during which Ergo may convert Series D Preferred Stock as previously
described, or an earlier date following the Trigger Event on which Ergo elects
not to convert Series D Preferred Stock into Common Stock, all outstanding
shares of Series D Preferred Stock will be automatically exchanged for a
subordinated promissory note of the Company (the "Exchange Note") in the
principal amount equal to the Stated Value of Series D Preferred Stock at the
date of exchange. The Exchange Note will be unsecured, will be subordinated to
all senior indebtedness, will bear interest at a rate equal to 2% above the
prime rate of Citibank, N.A., and will provide for twelve consecutive
quarterly payments, commencing on the three-month anniversary of the issuance
thereof.
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
  The Company is a Delaware corporation and is subject to Section 203 of the
Delaware General Corporation Law. In general, Section 203 prevents an
"interested stockholder" (defined generally as a person owning 15% or more of
the Company's outstanding voting stock) from engaging in a "business
combination" (as defined in Section 203) with the Company for three years
following the date that person becomes an interested stockholder unless (a)
before that person became an interested stockholder, the Company's Board of
Directors approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (b) upon
completion of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owns at least
85% of the voting stock outstanding at the time the transaction commenced
(excluding stock held by directors who are also officers of the Company and by
employee stock plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (c) following the transaction in which that
person became an interested stockholder, the business combination is approved
by the Company's Board of Directors and authorized at a meeting of
stockholders by the affirmative vote of the holders of at least 66 2/3% of the
outstanding voting stock not owned by the interested stockholder. Because the
transactions in which Hunt Financial and CVC became interested stockholders
were approved in advance by the Company's Board of Directors, Hunt Financial,
CVC and their affiliates will be exempt from the limitations of Section 203
pursuant to the exclusion described in clause (a). The Company has no plans to
engage in any transactions with Hunt Financial, CVC or their affiliates that
otherwise would be subject to Section 203. Section 203 provides that these
restrictions also do not apply to certain business combinations proposed by an
interested stockholder following the announcement or notification of one of
certain extraordinary transactions involving the Company and a person who was
not an interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the Company's
directors, if that extraordinary transaction is approved or not opposed by a
majority of the directors who were directors before any person became an
interested stockholder in the previous three years or who were recommended for
election or elected to succeed such directors by a majority of such directors
then in office.
 
  The Company's Board of Directors is divided into three classes. The
directors of each class are elected for three-year terms, with the terms of
the three classes staggered so that directors from a single class are elected
at each annual meeting of stockholders. Stockholders may remove a director
with or without cause upon the vote of holders of at least 66 2/3% of the
outstanding shares of Common Stock. In general, the Board of Directors, not
the stockholders, has the right to appoint persons to fill vacancies on the
Board of Directors.
 
  The Certificate of Incorporation provides that holders of Common Stock may
act only at annual or special meetings of holders of Common Stock and not by
written consent. The Certificate of Incorporation also provides that special
meetings of holders of Common Stock may be called only by the Company's Board
of Directors and that only business proposed by the Board of Directors may be
considered at special meetings of holders of Common Stock.
 
  The Certificate of Incorporation provides that the only business (including
election of directors) that may be considered at an annual meeting of holders
of Common Stock, in addition to business proposed (or persons nominated to be
directors) by the directors of the Company, is business proposed (or persons
nominated to be directors) by holders of Common Stock who comply with the
notice and disclosure requirements set forth in the
 
                                      51
<PAGE>
 
Certificate of Incorporation. In general, the Certificate of Incorporation
requires that a stockholder give the Company notice of proposed business or
nominations no later than 60 days before the annual meeting of holders of
Common Stock (meaning the date on which the meeting is first scheduled and not
postponements or adjournments thereof) or (if later) 10 days after the first
public notice of the annual meeting is sent to holders of Common Stock. In
general, the notice must also contain information about the stockholder
proposing the business or nomination, the stockholder's interest in the
business, and (with respect to nominations for director) information about the
nominee of the nature ordinarily required to be disclosed in public proxy
solicitation statements. The stockholder also must submit a notarized letter
from each of the stockholder's nominees stating the nominee's acceptance of
the nomination and indicating the nominee's intention to serve as director if
elected.
 
  The Delaware General Corporation Law provides generally that the affirmative
vote of a majority of the shares entitled to vote on any matter is required to
amend a corporation's certificate of incorporation or by-laws, unless the
corporation's certificate of incorporation or by-laws requires a greater
percentage. The Certificate of Incorporation provides that approval by the
holders of at least 66 2/3% of the outstanding voting stock of the Company is
required to amend the provisions of the Certificate of Incorporation
previously discussed and certain other provisions, except that approval of at
least 80% of the outstanding voting stock is required to amend the provisions
prohibiting holders of Common Stock from acting by written consent.
 
REGISTRATION RIGHTS
 
  The Company granted demand and piggyback registration rights to the
purchasers of its Series A, B and C Preferred Stock with respect to the Common
Stock issued upon conversion of that Preferred Stock, to the lenders under the
Loan Agreement with respect to the Common Stock issued in payment of the loan
at the closing of the Company's initial public offering, and to such holders
of Preferred Stock and lenders with respect to all shares of Common Stock they
held as of April 19, 1995. Approximately 4,133,247 shares of Common Stock are
entitled to these registration rights. Pursuant to these rights, a holder or
holders of 20% or more of the securities covered by the registration rights
agreement may make up to two requests for the Company to register under the
Securities Act of 1933 (the "Securities Act") the sale of Common Stock covered
by the agreement, subject to certain conditions. In addition, if the Company
files a registration statement in connection with an offering of its Common
Stock by it or its securityholders, the holders of these shares may request
that the Company include in that registration all or any portion of these
shares.
 
  The Company has also granted piggyback registration rights to Manuel
Cincotta, Jr., Dr. Anthony Cincotta, Dr. Albert Meier and other holders of
Common Stock pursuant to the Stockholder Rights Agreement, as amended, for
Ergo Science Incorporated effective August 5, 1992. Approximately 2,389,025
shares of Common Stock are entitled to these piggyback registration rights.
 
  The Company also granted piggyback registration rights to persons who
received Common Stock in connection with the issuance of the Series D
Preferred Stock. Approximately 536,576 shares of Common Stock are entitled to
these piggyback registration rights.
 
  Geneva obtained piggyback registration rights with respect to the 229,575
shares of Common Stock it received in connection with the signing of the
Geneva Agreement. See "Business--Commercialization Strategy--Manufacturing."
 
  The Company also granted piggyback registration rights with respect to the
20,000 shares of Common Stock subject to an option that the Company granted
its financial advisor upon the closing of its initial public offering.
 
  All of these registration rights are subject to cutback provisions. If the
underwriters of the offering advise the Company that inclusion of these
securities and any other securities held by other holders with piggyback
registration rights will have a material adverse effect on the amount, price
or distribution of the securities to be offered by the Company in the
offering, the aggregate number of shares to be included in the registration
will be allocated (i) 90% to the former holders of the Company's Series A,
Series B and Series C Preferred Stock and
 
                                      52
<PAGE>
 
lenders and (ii) 10% to all other security holders (including, without
limitation, the Company's management). The Company has agreed to pay all
expenses incurred by the holders of these registration rights in connection
with a registration, including certain legal fees and expenses, but excluding
underwriting discounts and commissions. None of these registration rights has
been exercised in connection with this offering. See "Principal and Selling
Stockholders."
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is The First National
Bank of Boston.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have 12,668,080 shares of
Common Stock outstanding. Of these shares, the 2,500,000 shares of Common
Stock sold in this offering will be, the 2,875,000 shares of Common Stock sold
in the Company's initial public offering are, and 22,500 shares of Common
Stock issued upon option exercises are, freely transferable without
restriction under the Securities Act unless they are held by the Company's
affiliates, as that term is used in Rule 144 under the Securities Act. The
Company issued the remaining 7,270,580 shares of Common Stock in reliance on
exemptions from the registration requirements of the Securities Act, and those
shares are restricted securities under Rule 144. Those shares may not be sold
publicly unless they are registered under the Securities Act, sold in
compliance with Rule 144, or sold in a transaction that is exempt from
registration. For purposes of Rule 144, the Company believes that none of the
Company's outstanding shares has a holding period that began before April 27,
1995, when the Company exchanged its capital stock for the capital stock of
Ergo Science Incorporated and interests in limited partnerships holding
licenses from the Company. Therefore, none of those shares will be eligible
for immediate sale in the public market without restriction under Rule 144(k),
and none of those shares will be eligible for immediate sale under the manner-
of-sale, volume and other limitations of Rule 144. Beginning April 27, 1997,
6,031,180 shares of Common Stock will become eligible for sale under Rule 144,
based on current SEC rules and subject to compliance with the manner-of-sale,
volume and other requirements of Rule 144, and the remaining outstanding
shares will become eligible for sale subject to those limitations at later
dates. Beginning April 27, 1998, those 6,031,180 shares of Common Stock will
become eligible for sale under Rule 144(k) if they are not held by affiliates
of the Company.
 
  In general, under Rule 144 a person (or persons whose sales are aggregated),
including an affiliate, who has beneficially owned shares for at least two
years is entitled to sell in broker transactions, within any three-month
period commencing 90 days after this offering, a number of shares that does
not exceed the greater of (i) 1% of the then outstanding Common Stock
(approximately 126,681 shares immediately after this offering) or (ii) the
average weekly trading volume in the Common Stock during the four calendar
weeks preceding the sale, subject to the filing of a Form 144 with respect to
the sale and other limitations. In addition, a person who was not an affiliate
of the Company during the three months preceding a sale and who has
beneficially owned the shares proposed to be sold for at least three years is
entitled to sell the shares under Rule 144(k) without regard to the manner-of-
sale, volume and other limitations of Rule 144. The SEC has proposed to
shorten the holding periods under Rule 144 for restricted securities. The SEC
has indicated that, if adopted, the proposed amendment would apply to all
outstanding restricted securities. However,        of those shares are subject
to lock-up agreements for 90 days after the date of this Prospectus. See
"Underwriting."
 
  The holders of approximately 3,877,275 shares of Common Stock and their
permitted transferees are entitled to demand registration of those shares
under the Securities Act. See "Description of Capital Stock--Registration
Rights."
 
  No prediction can be made of the effect, if any, that the sale or
availability for sale of shares of additional Common Stock will have on the
market price of the Common Stock. Nevertheless, sales of substantial numbers
of shares by existing stockholders or by stockholders purchasing in this
offering could have a negative effect on the market price of the Common Stock.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all of the Common Stock offered hereby if any of such shares are
purchased.
 
  The Company has been advised by the Representatives of the Underwriters that
the Underwriters propose to offer the shares of Common Stock to the public
initially at the price set forth on the cover page of this Prospectus and to
certain dealers at such price less a concession not in excess of $    per
share. The Underwriters may allow, and such dealers may reallow, a concession
not in excess of $    per share to certain other dealers. After the offering,
the offering price and other selling terms may be changed by the
Representatives of the Underwriters.
 
  The Company and the Selling Stockholders have granted to the Underwriters an
option, exercisable not later than 30 days after the date of this Prospectus,
to purchase up to 375,000 additional shares of Common Stock at the public
offering price less the underwriting discounts and commissions set forth on
the cover page of this Prospectus. To the extent that the Underwriters
exercise such option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage thereof that the number of shares
of Common Stock to be purchased by it shown in the above table bears to
2,500,000 and the Company and the Selling Stockholders will be obligated,
pursuant to the option, to sell such shares to the Underwriters. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of Common Stock offered hereby. If purchased, the
Underwriters will offer such additional shares on the same terms as those on
which the 2,500,000 shares are being offered.
 
  The Company and each Selling Stockholder that sells shares in the over-
allotment option have agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act.
 
  The Company, its directors, officers, principal stockholders and Selling
Stockholders have entered into agreements providing that, for a period of 90
days after the date of this Prospectus, they will not, without the prior
written consent of Cowen & Company, offer, sell, contract to sell or otherwise
dispose of any shares of Common Stock or any securities convertible into, or
exchangeable for, or warrants to purchase, any shares of Common Stock, or
grant any option to purchase or right to acquire or acquire any option to
dispose of any shares of Common Stock, except in certain limited
circumstances.

  The Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.
 
  In connection with this offering, certain Underwriters and selling group
members, if any, or their respective affiliates who are qualifying registered
market makers on the Nasdaq National Market may engage in passive market
making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 10b-6A under the Securities Exchange Act of 1934 (the
"Exchange Act"), during the two business days before commencement of offers or
sales of the Common Stock. The passive market making transactions must comply
with applicable volume and price limits and be identified as such. In general,
a passive market maker may display its bid at a price not in excess of the
highest independent bid for the security; if all independent bids are lowered
below the passive market makers' bid, however, the bid must then be lowered
when certain purchase limits are exceeded.
 
  Cowen & Company and Needham & Company, Inc. acted as co-managers of the
Company's initial public offering in December 1995, for which they received
customary commissions.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Ergo Science Corporation
(A Development Stage Enterprise):
 
  We have audited the accompanying consolidated balance sheets of Ergo Science
Corporation (the "Company") (a development stage enterprise) as of December
31, 1994 and 1995 and the related consolidated statements of operations and
deficit accumulated during the development stage, stockholders' equity
(deficit), and cash flows for the years then ended and the period cumulative
from inception (January 23, 1990) to December 31, 1995. 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 did not audit the financial statements of Ergo Science
Corporation for the period from inception to December 31, 1993. Such
statements are included in the cumulative totals from inception to December
31, 1995. The total net loss from inception to December 31, 1993 reflects 26%
of the cumulative total. Those statements were audited by other auditors whose
report has been furnished to us and our opinion, insofar as it relates to
amounts for the period from inception to December 31, 1993, included in the
cumulative totals, is based solely on the report of the other auditors.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Ergo Science Corporation as of
December 31, 1994 and 1995, and the results of its operations and its cash
flows for the years then ended and the period cumulative from inception
(January 23, 1990) to December 31, 1995, in conformity with generally accepted
accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES
 
 Organization
 
  Ergo Science Development Corporation ("Ergo") was incorporated on January
23, 1990. Ergo operated as an S Corporation from inception to September 10,
1992, when it converted to a C Corporation. In April 1995, Ergo went through a
recapitalization whereby all the stock of Ergo was exchanged on a one-for-one
basis for an equal amount of stock in Ergo Science Holdings, Incorporated,
previously a wholly-owned subsidiary of Ergo. Subsequent to the
recapitalization, Ergo Science Holdings, Incorporated changed its name to Ergo
Science Corporation (the "Company"). The consolidated financial statements
include the accounts of the Company and its subsidiaries, all of which are
wholly-owned. All intercompany accounts and transactions are eliminated upon
consolidation.
 
  The Company is a development stage enterprise as defined in Statement of
Financial Accounting Standards No. 7, and is devoting all of its efforts to
conducting research and development and raising capital to fund operations.
The ultimate success of the Company is dependent upon the development and
marketing of its products and its ability to secure adequate financing until
the Company is operating profitably.
 
 Research and Development Costs
 
  Research and development costs are expensed as incurred.
 
 Cash Equivalents and Investments
 
  The Company considers all highly liquid investments with a maturity of three
months or less at the date of purchase to be cash equivalents.
 
  Debt securities are classified as held-to-maturity when the Company has
positive intent and ability to hold the securities to maturity. Held-to-
maturity securities are stated at amortized cost. Debt securities not
classified as held-to-maturity are classified as available for sale and stated
at fair value.
 
  At December 31, 1994 and 1995 cash equivalents were composed primarily of
investments in money market funds and held-to-maturity securities with
original maturities of three months or less. Due to the nature of these
securities, there were no unrealized gains or losses at the balance sheet
dates. These investments consisted of United States Government obligations and
high grade commercial paper and asset backed securities that mature within 90
days of purchase. The held-to-maturity securities are recorded at their
amortized cost.
 
 Concentration of Credit Risk
 
  The Company has not realized any losses on its investments. The Company has
invested the net proceeds of its initial public offering in short-term,
interest-bearing, investment-grade securities, including U.S. Treasury and
agency securities and high-grade corporate notes.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates
and assumptions that effect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statement and the reported amounts of revenues and expenses during the
reported period. Actual results could differ from those estimates.
 
 Uncertainties
 
  The Company is subject to risks common to companies in the pharmaceutical
industry including, but not limited to, development by the Company or its
competitors of new technological innovations, dependence on key personnel,
protection of proprietary technology, and compliance with FDA governmental
regulations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED MARCH 31, 1995 AND 1996 IS
                                  UNAUDITED)
 
 Net Loss Per Common Share
 
  Net loss per common share is computed based upon the weighted average number
of common shares and common equivalent shares (using the treasury stock
method) outstanding after certain adjustments described below. Common
equivalent shares are not included in the per share calculations where the
effect of their inclusion would be anti-dilutive, except that, in accordance
with Securities and Exchange Commission Staff Accounting Bulletin No. 83, all
common and common equivalent shares issued during the twelve-month period
prior to the filing of the initial public offering, even when antidilutive,
have been included in the calculation as if they were outstanding for all
periods through September 30, 1995, using the treasury stock method. In the
computation of net loss per common share, accretion of preferred stock to the
mandatory redemption amount is included as an increase to net loss available
to common stockholders.
 
  Fully diluted net loss per common share is the same as primary net loss per
common share.
 
 Equipment and Leasehold Improvements
 
  Equipment and leasehold improvements are stated at cost. Depreciation is
calculated using straight-line basis over a 2 to 7 year estimated useful life.
Leasehold improvements are amortized over the shorter of the life of the
leases or the estimated useful life of the related assets. Repairs and
maintenance costs are charged to expense as incurred. Upon retirement or sale,
the cost of the assets disposed of and the related accumulated depreciation
are removed from the accounts and any resulting gain or loss is included in
the determination of net income.
 
 Capital Leases
 
  Assets and liabilities relating to capital leases are recorded at the
present value of the future minimum rental payments using interest rates
appropriate at the inception of the lease. Capital lease amortization is
included with depreciation and amortization expense.
 
 Organization Costs
 
  Certain costs associated with organizing the Company have been capitalized
and are being amortized on a straight-line basis over a period of five years.
 
 Income Taxes
 
  The Company accounts for income taxes using the asset and liability method
of accounting for income taxes.
 
 Stock-Based Compensation
 
  In October 1995, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS 123") was issued and will
require the Company to elect either expense recognition under FAS 123 or its
disclosure-only alternative for stock-based employee compensation. The expense
recognition provision encouraged by FAS 123 would require fair-value based
financial accounting to recognize compensation expense for employee stock
compensation plans. FAS 123 must be adopted in the Company's fiscal 1996
financial statements with comparable disclosures for the prior years. The
Company has determined that it will elect the disclosure-only alternative. The
Company will be required to disclose the pro forma net income or loss and per
share amounts in the notes to the financial statements using the fair-value
based method beginning in fiscal 1996 with comparable disclosures for fiscal
1995. The Company has not determined the impact of these pro forma
adjustments.

</TABLE>
 
  Since held-to-maturity securities are short-term in nature, changes in
market interest rates would not have a significant impact on fair value of
these securities. These securities are carried at amortized cost which
approximate fair value. All short-term investments mature within 183 days of
December 31, 1995.

  The changes in the total valuation allowance for the years ended December
31, 1994 and 1995 were increases of $3,942,000 and $6,092,000 respectively.
 
  During 1993, the Company converted from the cash basis to the accrual basis
for income tax purposes. As of December 31, 1995, the Company had net
operating loss carry forwards for income tax purposes of approximately $30
million which expire through 2009. The Company's ability to use the carry
forwards is subject to limitations resulting from an ownership change as
defined in Internal Revenue Code Sections 382 and 383.
 
6. CAPITAL STOCK
 
  In October 1995, the Board of Directors increased the number of authorized
shares of common stock to 50,000,000 and the authorized number of shares of
preferred stock to 10,000,000. The Board of Directors may establish, without
stockholder approval, one or more classes or series of preferred stock having
the number of shares, designations, relative voting rights, dividend rates,
liquidation and other rights, preferences and limitations that the Board of
Directors may designate. Also in October 1995, the Company effected a 25-for-1

stock split and converted all shares of the Company's Class A Common Stock and
Class B Common Stock into one class of common stock. Accordingly, all share
and per share amounts have been adjusted to reflect the stock splits and the
Class A/Class B conversion as though they had occurred at the beginning of the
initial period presented.
 
  On September 10, 1992, the Company issued $3,500,000 principal amount of
Series A 6% convertible notes for cash at face value. On October 12, 1993, the
Company converted the $3,500,000 of Series A 6% convertible notes into 8,826
shares of Voting Series A 6% Redeemable Convertible Preferred Stock, $.01 par
value, with a stated value of $3,730,750. In connection therewith, the Company
recognized a charge to expense of $48,458 representing the remaining
unamortized balance of the deferred issuance costs.
 
  On October 12, 1993, the Company sold 20,940 shares of Voting Series B 6%
Redeemable Convertible Preferred Stock, $.01 par value, for an aggregate
amount of $10,041,986.
 
  On July 15, 1994, the Company sold 6,255 shares of Voting Series C 6%
Redeemable Convertible Preferred Stock, $.01 par value, for an aggregate
amount of $2,999,605.
 
  Each share of Series A, Series B, and Series C 6% Redeemable Convertible
Preferred Stock (the "Preferred Stock") was convertible, at the option of the
stockholder, into common stock by dividing the stated value for each share
adjusted for unpaid and undeclared dividends (in effect at the time) by the
conversion price (in effect at the time). The conversion price of the
Preferred Stock was subject to adjustment under certain conditions identified
in the agreement, and automatically converted upon the closing of the public
offering into shares of common stock of the Company, at the conversion price
in effect at the time.
 
  The holders of Preferred Stock were also entitled to voting rights equal to
the number of common shares into which the preferred shares would have been
converted into at the time. The holders of Series A and Series C Preferred
Stock each had the right to elect one member to the Board of Directors. The
holders of Series B Preferred Stock had the right to elect two members to the
Board of Directors. Such voting power terminated upon the public offering.
 
  The holders of Preferred Stock were entitled to receive quarterly cash
dividends at a rate of 6% per annum, compounded semi-annually, on the stated
value thereof, commencing November 1, 1993, for Series A and Series B
Preferred Stock and August 1, 1994 for Series C Preferred Stock. Accumulated
and unpaid dividends were accreted and charged to cumulative dividends on
redeemable preferred stock. Such dividends were cumulative, commencing on the
date of original issue, and payable to holders of record when and as declared
by the Board of Directors. The dividend value of the Preferred Stock was
$31.64, $35.83 and $13.22 per share for Series A, Series B and Series C
Preferred Stock, respectively, at December 31, 1994. Unpaid and undeclared
dividends to holders of Preferred Stock amounting to $509,525, $750,373 and
$82,675 for Series A, Series B and Series C, respectively, had been accreted
in cumulative dividends on redeemable preferred stock at December 31, 1994.
 
  In the event of liquidation, the holders of Preferred Stock were entitled to
be paid a liquidation amount equal to the greater of the conversion amount per
share at the time or the stated value per share at the time. As of December
31, 1994, the aggregate liquidation values, of the Series A, Series B and
Series C Preferred Stock were $4,009,525, $10,792,359 and $3,082,325,
respectively.
 
  On May 30, 1995, the Company sold 10,426 shares of Series C Preferred Stock,
par value $.01, for $4,999,892.

  On September 1, 1995, the Series A, Series B and Series C Preferred Stock
designations were amended. The affect of this amendment was to cancel the
accretion of dividends on the Series A Preferred Stock since its conversion on
October 13, 1993, and the accretion on Series B and Series C Preferred Stocks
since their issuance and to reset the stated values at September 1, 1995 to
the original stated values of each series. The Company re-commenced accreting
dividends on September 1, 1995. In connection with these amendments, the
Company recorded a preferred stock dividend in the amount of $7,123,536 which
reflects the difference between the $9.00 per share fair market value of the
Company's common stock on the date of amendments and the $6.41 per share
amended weighted average conversion price of the Series A, B and C Preferred
Stock, multiplied by the number of additional shares of common stock those
preferred stockholders received upon conversion.
 
  In September 1995, the Company obtained a loan commitment from the holders
of the Series A, B and C Preferred Stock for an amount up to $6,000,000. The
Company received an initial advance against this commitment of $1,000,000 and
had the option to draw further advances in installments of $1,000,000.
Outstanding amounts bore interest at 10% and would mature at the earlier of
the closing of a private placement, the closing of an initial public offering
("IPO"), or January 31, 1996. Upon the maturity of the outstanding amounts
which resulted from the closing of the IPO the Company issued the investors
451,767 shares of common stock of the Company equal to the outstanding amount,
$4,065,949 divided by $9.00 per share in full satisfaction of amounts under
the loan.
 
  On December 19, 1995, the Company completed its IPO and sold an aggregate of
2,875,000 shares of common stock at $9.00 per share resulting in net proceeds,
after deducting underwriting discounts and offering costs, of approximately
$23,030,476. In addition, upon the closing of the IPO, the Series A, B and C
Preferred Stock including all applicable dividends accreted in cumulative
dividends on redeemable preferred stock since September 1, 1995, were
automatically converted into shares of common stock in accordance with the
underlying agreements.
 
  On April 27, 1995, in connection with a revised license and royalty
agreement negotiated with Louisiana State University ("LSU"), the Company
issued 125,000 shares of common stock to certain inventors, including two
members of the Company's Board of Directors. The shares were issued in
exchange for the inventors' share of the royalty obligation the Company has
under the royalty agreement with LSU. Accordingly, the Company recorded a
$2,000,000 charge for the purchase of in-process research and development.
 
  See Note 7 for a description of Series D Preferred Stock.
 
7. LICENSE AGREEMENTS AND SUPPLIER CONTRACTS
 
  In the fall of 1991, the Company entered into an exclusive licensing
arrangement with an investment group organized in New England (the "New
England Group"). Under the terms of this arrangement, a partnership (the "New
England Venture") organized by the investment group acquired an exclusive
license arrangement to commercialize the Company's products and medical
protocols in the six New England States. In the spring of 1992, the Company,
the New England Group, and a group of investors in Florida organized a
partnership (the "Florida Venture") to commercialize the Company's products
and medical protocols in the state of Florida. The Company entered into a
license arrangement with the Florida Venture to commercialize the products and
medical protocols in Florida.
 
  In the fall of 1992, the Company organized a partnership to commercialize
the Company's products and medical protocols in the state of Louisiana (the
"Louisiana Venture"). The Company entered into a license arrangement with the
Louisiana Venture to commercialize the products and medical protocols in
Louisiana.

  During 1991 and 1993, the Company received fees from two suppliers for the
exclusive right to supply the Company with certain drug products. In exchange,
the Company agreed to purchase all of its drug requirements from the suppliers
at agreed upon prices.
 
  $1,950,000 of the license fees and $1,750,000 of the supplier contracts fees
received by the Company were characterized as nonrefundable in the respective
agreements. Through December 31, 1992, such nonrefundable fees were recognized
as revenue over the period from receipt of funds to the estimated date of FDA
approval because of the Company's obligations to perform research and sponsor
clinical trials prior to that approval. However, during 1993, the Company
began discussions with the sublicensees about exchanging their sublicense
rights for the Company's common stock. The Company also began discussions with
suppliers to renegotiate the supply contracts to fit more closely the
redesigned plan for commercialization of its products. Therefore, no
additional deferred revenue from sublicensing fees and from supplier contracts
had been recognized in 1993 and 1994.
 
  Effective January 1, 1995, the Company renegotiated the contract with one of
its drug suppliers. In recognition of the supplier's initial contribution of
its supply agreement fee to fund the Company's drug development efforts, the
Company issued 156,400 shares of common stock, par value $.01. The Company
assigned a value of $16.00 per share; the value assigned in excess of the
unamortized deferred revenue from the fees previously received resulted in a
net charge to operations of $1,089,356 in January 1995. The Company
subsequently issued an additional 73,175 shares of common stock to the
supplier under antidilution provisions of the renegotiated agreement, which
resulted in a net charge to operations of $658,575 in November 1995.
 
  In September 1995, the Company terminated its manufacturing agreement with
the other drug supplier and recorded a charge of $215,385 for a cash payment
to that supplier.
 
  In April 1995, the Company went through a recapitalization whereby all the
stock of the Company was exchanged on a one-for-one basis for an equal amount
of stock in Ergo Science Holdings, Incorporated, previously a wholly-owned
subsidiary of the Company. Subsequent to the recapitalization, Ergo Science
Holdings, Inc. changed its name to Ergo Science Corporation.
 
  As a result of the redesigned plan for commercialization of the Company's
products, territorial sublicenses were no longer commercially feasible for the
partnerships. Accordingly, on April 27, 1995, the Company effectively canceled
the partnership sublicenses by acquiring all the partners' interests in the
New England Venture, the Florida Venture and the Louisiana Venture. Rather
than return the sublicense fees, including both the refundable and unamortized
nonrefundable portions originally contributed by the partnerships, the Company
issued 278,875 shares of common stock and 5,618 shares of Series D Preferred
Stock, par value $.01. The Company ascribed a value of $16.00 per share to the
common stock issued and $584.00 per share to the Series D Preferred Stock. The
excess of fair value of the stock issued over the related unamortized deferred
revenue resulted in a net charge to operations of $3,520,000 for the purchase
of in-process research and development.
 
  The holders of Series D Preferred Stock are also entitled to receive
quarterly cash dividends at a rate of 6% per annum compounded semiannually on
the stated value. Such dividends shall be cumulative, commencing on the date
of original issue, and shall be payable to holders of record, when and as
declared, by the Board of Directors. The Company will have the option to
convert the Series D Preferred Stock into common stock during the 90 days
after the Company receives FDA approval to market its first product, if it
receives that approval. If the Company does not exercise its option to convert
the Series D Preferred Stock into common stock within the

90 days, the Series D Preferred Stock will automatically be exchanged for
subordinated debt securities at the end of the 90 days. The Company currently
intends to exercise its option to convert the Series D Preferred Stock to
common stock if a Trigger Event occurs, and, accordingly, the Series D
Preferred Stock was recharacterized as Preferred Stock upon closing of the
IPO. The terms of the Company's Series D Preferred Stock prohibit the Company
from paying dividends on the common stock.
 
  On April 27, 1995, in conjunction with the recapitalization, the Company
also sold 1,285 shares of the Series D Preferred Stock, par value $.01 and
33,400 shares of common stock, par value $.01, for $1,285,000.
 
  In November 1995, the Company declared a dividend of 224,307 shares of
common stock to the holders of Series D Preferred Stock and, accordingly,
recorded a charge in the fourth quarter of $2,018,763 to net loss to common
stockholders.

  At December 31, 1995 and March 31, 1996 there were 454,175 and 431,675
options exercisable, respectively. In connection with the issuance of stock
options at exercise prices below fair market value, as determined by the
Company's Board of Directors, the Company recorded compensation expense of
$253,942 and $490,961 for the years ended December 31, 1994 and 1995,
respectively, and $199,081 for the three months ended March 31, 1996. There
were no stock options issued at exercise prices below fair market value in the
three months ended March 31, 1996. The $1,650,069 remaining deferred
compensation at March 31, 1996 will be amortized over the vesting periods of
the underlying options.
 
  Effective as of November 1, 1994, the Board of Directors adopted the Ergo
Science Development Corporation Long-Term Incentive Plan (the "Incentive
Plan") pursuant to which certain officers, directors, and key employees may be
granted awards with respect to shares of the Company's common stock. The
awards which may be granted under the Incentive Plan include incentive and
nonqualified stock options, stock appreciation rights ("SARs") and restricted
stock awards. At December 31, 1995 and March 31, 1996, the aggregate number of
shares of the Company's common stock which could be issued pursuant to
incentive awards under the Incentive Plan was 731,525 shares (for which common
shares have been reserved). Awards of options to provide 7,500, 631,625 and
25,000 shares at exercise prices of $0.80, $6.71-$9.00 and $22.00 per share,
respectively, were granted under the Incentive Plan during the years ended
December 31, 1994 and 1995 and during the three month period ended March 31,
1996, respectively. These amounts are included in the table above.

10. COMMITMENTS AND CONTINGENCIES
 
  The Company has a royalty agreement with LSU under which the Company pays
LSU a royalty based upon gross sales. The Company also has a commitment to
make payments of an agreed percentage of net cash flow to LSU once the Company
generates positive net cash flow, as defined in the agreement. LSU is
obligated to expend substantially all of such net cash flow payments from the
Company on research supervised by one of the Company's consultants (or the
Company's designee), and the Company has the option of licensing any patents
that arise from such research.
 
  On May 1, 1995, Ergo Research Corporation, a wholly-owned subsidiary of the
Company, entered into a novative license and royalty agreement with LSU that
replaces the royalty agreement with LSU described in the prior paragraph. The
new agreement required an initial fee of $200,000 paid to LSU upon execution
and charged to operations as the purchase of in-process research and
development, $500,000 paid upon the IPO and the issuance of 18,750 common
shares one year after the IPO. The agreement requires additional fees of
$350,000 for the first and $500,000 for all subsequent administrative
approvals of licensed pharmaceutical products. The Company must pay LSU a
royalty based upon gross sales with minimum royalties due.
 
11. NONCASH INVESTING AND FINANCING ACTIVITIES
 
  Capital lease obligations are considered noncash items and, accordingly, are
not reflected in the consolidated statements of cash flows. Capital lease
obligations of $123,502 and $58,290 were incurred in 1994 and 1995,
respectively, when the Company entered into leases for lab and office
equipment.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Registrant's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") provides that no director of the Registrant
will be personally liable to the Registrant or any of its stockholders for
monetary damages arising from the director's breach of fiduciary duty as a
director. However, this does not apply with respect to any action in which the
director would be liable under Section 174 of Title 8 of the General
Corporation Law of Delaware nor does it apply with respect to any liability in
which the director (i) breached his duty of loyalty to the Registrant; (ii)
did not act in good faith or, in failing to act, did not act in good faith;
(iii) acted in a manner involving intentional misconduct or a knowing
violation of law or, in failing to act, shall have acted in a manner involving
intentional misconduct or a knowing violation of law; or (iv) derived an
improper personal benefit.
 
  The Certificate of Incorporation provides that the Registrant will indemnify
its officers and directors and former officers and directors against any
expenses, judgments or settlement payments sustained or paid by such persons
as a result of having acted as an officer or director of the Registrant, or,
at the request of the Registrant, as an officer, director, agent or employee
of another business entity. The Certificate of Incorporation further provides
that the Registrant may, by action of its Board of Directors, provide
indemnification to employees and agents of the Registrant, individually or as
a group, with the same scope and effect as the indemnification of directors
and officers.
 
  The Registrant has entered into indemnification agreements with each of its
directors and executive officers providing for the indemnification of those
persons to the fullest extent permitted by law, together with the advancement
of expenses, in the event they become a party to or witness or other
participant in any threatened, pending or completed action, suit or proceeding
(a "Claim") by reason of any event or occurrence related to the fact that any
such person is or was a director, officer, employee, agent or fiduciary of the
Registrant or a subsidiary of the Registrant or another entity at the
Registrant's request (an "Indemnifiable Event"), unless a reviewing party
(either a committee appointed by the Board of Directors or outside counsel)
shall have determined that such person would not be entitled to
indemnification under applicable law. In addition, in the event of a Change in
Control or a Potential Change in Control of the Registrant (as defined in the
indemnification agreements), the Registrant will, upon the request of an
indemnitee, establish a trust for the benefit of the
 
                                     II-1
<PAGE>
 
indemnitee and fund the trust in an amount sufficient to satisfy all expenses
reasonably anticipated at the time of the request to be incurred in connection
with any Claim relating to an Indemnifiable Event. The amount deposited in the
trust will be determined by the reviewing party. An indemnitee's rights under
the indemnification agreement are not exclusive of any other rights under the
Certificate of Incorporation, the Registrant's Third Amended and Restated By-
laws or applicable law.
 
  Under Section 145 of the General Corporation Law of Delaware, every Delaware
corporation has the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (other than an action by or in the right of the
corporation) by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation or, at the corporation's
request, any other corporation, partnership, joint venture, trust or other
enterprise, against any and all expenses, judgments, fines and amounts paid in
settlement and reasonably incurred in connection with such action, suit or
proceeding. The power to indemnify applies only if the person acted in good
faith and in a manner the person reasonably believed to be in the best
interest, or not opposed to the best interest, of the corporation and with
respect to any criminal action or proceeding, had no reasonable cause to
believe the person's conduct was unlawful.
 
  The power to indemnify applies to actions brought by or in the right of the
corporation as well, but only to the extent of defense and settlement expenses
and not to any satisfaction of a judgment or settlement of the claim itself,
and with the further limitation that in such actions no indemnification may be
made in the event of any adjudication of negligence or misconduct unless the
court, in its discretion, believes that in light of all the circumstances
indemnification should apply.
 
  To the extent any person referred to in the two immediately preceding
paragraphs is successful in the defense of the actions referred to therein,
that person is entitled to indemnification under Section 145 of the General
Corporation Law of Delaware as previously described.
 
  The Registrant maintains insurance that insures the officers and directors
of the Registrant against certain losses and that insures the Registrant
against certain of its obligations to indemnify such officers and directors.
 
  The form of underwriting agreement included as Exhibit 1 provides for
indemnification of the Registrant and certain controlling persons under
certain circumstances, including indemnification for liabilities under the
Securities Act of 1933 (the "Securities Act"). The Registrant is a party to
registration rights agreements that contain similar indemnification
provisions.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
  References to the Company in this Item 15 for events before April 27, 1995,
include the Company's predecessor, Ergo Science Incorporated, which is now a
subsidiary of the Company.
 
  On October 12, 1993, Citicorp Venture Capital Ltd. ("CVC"), Citi Growth
Fund, L.P. ("Citi Growth"), certain CVC employees (including Mr. McWilliams, a
director of the Company), Hunt Financial Corporation ("Hunt Financial"), and
another entity purchased 20,940 shares of the Company's Series B Preferred
Stock for $10,041,986. This transaction did not involve a public offering and
was done in reliance on Section 4(2) of the Securities Act and Rule 506 of
Regulation D. Concurrently with this purchase of Series B Preferred Stock,
purchasers of the Company's Series A Notes in September 1992 converted the
Series A Notes into 8,826 shares of the Company's Series A Preferred Stock.
The issuance of the Series A Preferred Stock upon conversion of the Series A
Notes was done in reliance on Section 3(a)(9) of the Securities Act.
 
  On July 15, 1994, Hunt Financial purchased 6,255 shares of the Company's
Series C Preferred Stock for $2,999,647. With this purchase of Series C
Preferred Stock, the Company issued to Hunt Financial, for $.0004 per warrant,

share. Effective
 
                                     II-2
<PAGE>
 
May 30, 1995, Hunt Financial purchased an additional 10,426 shares of the
Company's Series C Preferred Stock for $4,999,892. With this second purchase
of Series C Preferred Stock, the Company issued to Hunt Financial for $.0004
per warrant, warrants to purchase 50,650 shares of the Company's Common Stock
at $16.20 per share. These warrants were canceled in September 1995. Each of
these transactions did not involve a public offering and was done in reliance
on Section 4(2) of the Securities Act and Rule 506 of Regulation D.
 
  On January 1, 1995, the Company entered into a renegotiated supply agreement
with Geneva Pharmaceuticals, Inc., a Colorado corporation ("Geneva"). In
connection with the renegotiation, the Company issued to Geneva 156,400 shares
(after adjustment to reflect the October 1995 25-for-1 stock split) of Common
Stock for $1,413,044 in fees previously received under the contract. The
Company subsequently issued an additional 73,175 shares of Common Stock to
Geneva under antidilution provisions of the renegotiated agreement. The
transaction did not involve a public offering and was done in reliance on
Section 4(2) of the Securities Act and Rule 506 of Regulation D.
 
  In April 1995, the Company issued 60,000 shares of Common Stock to a
director, Dr. Anthony Cincotta; 60,000 shares to another director, Dr. Albert
Meier; and 5,000 shares to an employee. The issuance was consideration to
acquire from those individuals royalty rights which they had as inventors of
certain technology owned by Louisiana State University and Agricultural and
Mechanical College and licensed to the Company. This transaction did not
involve a public offering and was done in reliance on Section 4(2) of the
Securities Act and Rule 506 of Regulation D.
 
  On April 27, 1995, the Company issued 6,971,875 shares of Common Stock
(after giving effect to the October 1995 25-for-1 split of the Common Stock)
and 5,618 shares of Series D Preferred Stock in exchange for partnership
interests in limited partnerships that previously had purchased cash licenses
from the Company for the use of certain of the Company's technologies. Also,
on April 27, 1995, the Company issued 835,000 shares of Common Stock (after
giving effect to the October 1995 25-for-1 split of the Common Stock) and
1,285 shares of Series D Preferred Stock for $1,285,000 in cash. Also on April
27 ,1995, the Company exchanged shares of its Common Stock and Series A,
Series B and Series C Preferred Stock for the corresponding classes of capital
stock of its parent company, Ergo Science Incorporated, which is now a
subsidiary of the Company. Each of these transactions did not involve a public
offering and was made in reliance on Section 4(2) of the Securities Act and
Rule 506 of Regulation D.
 
  On September 1, 1995, CVC, Citi Growth, certain CVC employees including Mr.
McWilliams, Hunt Financial, and Lafayette Investment Company (a company
controlled by Ray L. Hunt, a director of the Company) entered into a loan
agreement pursuant to which they agreed to lend the Company up to $6,000,000.
This transaction did not involve a public offering and was done in reliance on
Section 4(2) of the Securities Act and Rule 506 of Regulation D.
 
  Upon the closing of the Company's initial public offering in December 1995,
the principal of and accrued interest on this loan were converted into Common
Stock at a valuation of $9.00 per share. Also upon closing of the Company's
initial public offering, all outstanding shares of preferred stock (other than
the Series D Preferred Stock) were automatically converted into Common Stock
of the Company. These transactions were done in reliance on Section 3(a)(9) of
the Securities Act.
 
  In October 1995, the Company declared a dividend of Common Stock to the
holders of Series D Preferred Stock. This transaction did not involve a sale.
 
  During 1992, 1993, 1994 and 1995 the Company granted options to purchase an
aggregate of 1,147,600 shares of Common Stock (after giving effect to the
October 1995 25-for-1 split of the Common Stock) to directors, officers and
key employees. Certain of those options have been exercised. These
transactions did not involve a public offering and were done in reliance on
Section 4(2) of the Securities Act.

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes that:
 
    (1) 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 a 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 this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose 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.
 
  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 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.
