                                  THE COMPANY
 
    The Company is engaged primarily in the discovery, development, clinical
testing and marketing of proprietary plant-based pharmaceuticals
(phyto-pharmaceuticals) for the treatment of chronic, difficult-to-treat human
diseases. The Company currently has three phyto-pharmaceutical products in
various stages of clinical and preclinical development. RA-11, the Company's
lead phyto-pharmaceutical, is currently being test-marketed in India for the
treatment of arthritis; IM-10, which is undergoing preclinical animal
pharmacology testing in India, has been indicated for the stimulation and
restoration of bone marrow and the immune system in cancer patients being
treated with chemotherapy; and HP-11, an early-stage product candidate, is
undergoing laboratory testing in India for the treatment of hepatitis. The
Company has an exclusive license under a United States patent relating to RA-11
and its use in treating degenerative musculoskeletal diseases. In addition, the
Company has a patent application pending relating to BV-6, a pharmaceutical
derived from a single animal cell component, which is undergoing early
pharmacological studies at Emory University for the treatment of degenerative
diseases of the central nervous system.
 
    A key element of the Company's strategy is to apply the principles of
Ayurveda, an ancient science native to India, to reduce the time and costs
associated with the drug discovery process. Generations of Ayurveda scholars
have studied and documented the uses and efficacy of specific plants as
medicinal therapies over a period of several hundreds of years. Their findings,
preserved and detailed in Ayurvedic literature, provide valuable information for
modern day scientists. Through the study of Ayurveda, the Company's scientific
team seeks to rapidly identify plants, or combinations of plants, that have been
successfully used to treat symptoms and ailments characteristic of the diseases
targeted by the Company. In addition, because Ayurvedic literature has also
documented the safety of over 300 plant extracts for human use, once an
Ayurvedic plant candidate has been identified by the Company's researchers, they
are, in many instances, able to conduct early development activities in
parallel, rather than sequentially, when determining the candidate's safety and
efficacy. The Company believes that focusing its screening process on plants
whose safety and efficacy in medicinal use have been documented in Ayurvedic
literature will result in faster and more effective screening methods for the
discovery of new phyto-pharmaceuticals. The Company further believes that, based
on their long histories of safe use, these phyto-pharmaceuticals will have a
greater potential for safety and, as a result, may achieve more rapid regulatory
approval.
 
    The Company's research and development activities are primarily conducted by
the Company's Indian subsidiary at laboratories located in Pune, India, which
are staffed with 15 full time employees and 12 consultants. There, the Company's
India-based scientists are able to study the Ayurvedic literature (primarily
written in the ancient Sanskrit language) to accelerate the plant screening
process. In addition, by conducting operations in India, the Company is able to
access highly skilled scientific talent and other resources at an estimated
one-tenth of the cost of comparable labor and resources in the United States.
Although the Company's clinical trials to date have only been conducted in
India, they have been administered in accordance with protocols designed to be
consistent with the standards of the United States Food and Drug Administration
(the "FDA") and in laboratories that operate in accordance with FDA Good
Laboratory Practices ("GLP") guidelines. In addition, the Company's proprietary
plant extraction process is conducted for it by Kancor Flavours & Extracts Pvt.
Ltd., a third-party Indian supplier with an ISO-9000 certification (a worldwide
industry manufacturing standard). The Company has thus
 
                                       3
<PAGE>
established, and continues to enhance, a network infrastructure in India
designed to identify phyto-pharmaceuticals through an accelerated process and in
a low-cost, high quality environment.
 
    RA-11, the Company's lead product, has been derived, initially through
Ayurvedic studies, from a combination of four different plant species. The
Company holds an exclusive license on two Indian patents relating to its
proprietary plant extraction and RA-11 formulation processes, as well as a
United States patent relating to RA-11 and its use in treating degenerative
musculoskeletal diseases, such as rheumatoid arthritis and osteoarthritis.
Incidence of rheumatoid arthritis is reported to be approximately 2% of the
world population and the incidence of clinically symptomatic osteoarthritis is
reported to be between 10-15% worldwide. Moreover, in 1996, arthritis in general
was reported by the American College of Rheumatology ("ACR") to be the number
one cause of disability in the United States and the total market for
prescription arthritis drug therapy was estimated to be over $6 billion. Based
on clinical trials conducted in India (where RA-11 has been approved for
commercial sale by India's FDA equivalent) under protocols consistent with FDA
guidelines and ACR criteria, the Company believes that RA-11 may prove to be an
effective and safe drug for long-term treatment of osteoarthritis and may be
classified as a disease modifying, anti-rheumatic drug for the long-term
treatment of rheumatoid arthritis.
 
    Effective September 1997, the Company entered into a three-year distribution
agreement with a Singapore-based pharmaceutical marketing and distribution
company, MD Pharmaceuticals Laboratories Ltd., for the distribution of RA-11 in
certain Pacific Rim countries and expects marketing to commence under such
agreement during the first half of 1998. In addition, RA-11 is currently being
test-marketed in India under an agreement with Alembic Chemical Works Co.
Limited, an Indian pharmaceutical company. The Company intends to file an
investigational new drug ("IND") application for RA-11 with the FDA in the
United States during the first quarter of 1998. Subject to approval of its IND
application, of which there can be no assurance, the Company will seek to
by-pass Phase I clinical trials (preliminary trials which focus on healthy human
subjects) in the United States, proceeding directly to Phase II clinical studies
(intermediate level trials, focused on a limited target patient population),
since it has already conducted two large, well-documented efficacy and safety
Phase II level clinical trials in India using protocols consistent with FDA
guidelines. The Company does not, however, anticipate completing clinical trials
or filing a new drug application ("NDA") with the FDA for RA-11 (approval of
which must be obtained prior to the commencement of its commercial sale in the
United States) until, at the earliest, the year 2001.
 
    The Company is in the development stage and has not yet had any of its
products approved by the FDA. The Company's long-term viability, profitability
and growth will depend upon successful commercialization of products resulting
from its research and development activities. To date, the Company has recorded
only limited product sales revenues ($83,000 as of September 30, 1997), and
these have been derived primarily from sales in India of SA-12, a proprietary
anti-bacterial surgical scrub acquired by the Company from its inventor in 1995.
As a result, the Company has incurred significant operating losses since its
inception, including operating losses of $1,146,000, $1,245,000 and $596,000 for
the years ended December 31, 1995 and 1996 and the nine months ended September
30, 1997, respectively. The Company expects that its losses will increase as the
Company expands its product development activities and that they will continue
until such time, if ever, as the Company is able to generate sufficient revenues
to support its operations. The Company believes that its ability to generate
sufficient revenues primarily depends on the success of the Company in
completing development, and obtaining regulatory approvals for the commercial
sale, of RA-11 and other product candidates. There can be no assurance that any
of such events will occur or that the Company will ever achieve profitable
operations. See "Risk Factors."
 
    The Company is a Delaware corporation which was organized on January 11,
1993 under the name Bio-Ved, Inc. The Company changed its name to AyurCore, Inc.
on September 27, 1995. The Company has one substantially wholly-owned
subsidiary, BIO-VED Pharmaceuticals Private Limited, a company organized in
India ("Bio-Ved"). Unless the context otherwise requires, all references herein
to the "Company" shall be deemed to include and refer to AyurCore, Inc. and
Bio-Ved. The Company's principal executive office is located at 1737 N. First

(1) Net loss per share is computed based upon the weighted average number of
    shares of Common Stock outstanding during the periods. Pursuant to the
    requirements of the Commission, all Common Stock and Common Stock
    equivalents issued within the 12 months immediately preceding the initial
    filing of the Registration Statement of which this Prospectus forms a part,
    at a price below the assumed offering price of $6.00 per share (the midpoint
    of the currently anticipated range of the initial public offering price per
    share), have been included in the weighted average number of shares
    outstanding for all periods presented, utilizing the "treasury stock
    method."
 
(2) Gives effect to (i) the Note Conversion which was effected as of October 31,
    1997 (including the conversion of interest accrued in October 1997), (ii)
    the issuance of the October 1997 Warrants, and (iii) the modification,
    effective December 1, 1997, of the terms of approximately $230,000 in
    principal amount of short-term debt, plus accrued interest thereon ($21,000
    as of September 30, 1997), resulting in its reclassification as long-term
    debt. See "Plan of Operation--Liquidity and Capital Resources."
 
(3) As adjusted to give effect to the sale of the 1,250,000 shares of Common
    Stock offered hereby at an assumed price of $6.00 per share (the midpoint of
    the currently anticipated range of the initial public offering price) and
    the anticipated application of the estimated net proceeds therefrom,
    including repayment of certain indebtedness (approximately $670,000 in
    outstanding principal and interest as of September 30, 1997). See "Use of
    Proceeds."

                                  RISK FACTORS
 
    THE SECURITIES BEING OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK AND SHOULD
BE PURCHASED ONLY BY PERSONS WHO CAN AFFORD THE LOSS OF THEIR ENTIRE INVESTMENT.
THE FOLLOWING RISK FACTORS, IN ADDITION TO THE OTHER INFORMATION AND FINANCIAL
DATA SET FORTH IN THIS PROSPECTUS, SHOULD BE CONSIDERED CAREFULLY IN EVALUATING
THE COMPANY AND ITS BUSINESS BEFORE MAKING AN INVESTMENT IN THE SHARES. THE
RISKS DESCRIBED BELOW AND ELSEWHERE IN THIS PROSPECTUS ARE NOT INTENDED TO BE AN
EXHAUSTIVE LIST OF THE GENERAL OR SPECIFIC RISKS INVOLVED, BUT MERELY IDENTIFY
CERTAIN RISKS THAT ARE NOW FORESEEN BY THE COMPANY. IT MUST BE RECOGNIZED THAT
OTHER RISKS, NOT NOW FORESEEN, MIGHT BECOME SIGNIFICANT IN THE FUTURE AND THAT
THE RISKS WHICH ARE NOW FORESEEN MIGHT AFFECT THE COMPANY TO A GREATER EXTENT
THAN IS NOW FORESEEN OR IN A MANNER NOT NOW CONTEMPLATED.
 
    EARLY STAGE OF PRODUCT DEVELOPMENT; NO ASSURANCE OF SUCCESSFUL PRODUCT
DEVELOPMENT.  None of the Company's products or product candidates have been
approved for sale in the United States or Europe or in other countries with
comparable regulatory approval processes. The Company's products and product
candidates are in various stages of development and will require significant
additional development, clinical testing and investment prior to
commercialization in the United States and other countries. Products for use in
human healthcare must be evaluated in extensive human clinical trials to
determine their safety and efficacy as part of a lengthy process to obtain
government approval. Clinical trials may be terminated at any time for many
reasons, including safety or lack of efficacy. There can be no assurance that
the Company will not encounter problems in clinical trials that will cause the
Company to delay or suspend any trials which it may conduct. Further, there can
be no assurance that the Company's research and development efforts will be
successful or that any products developed will be safe, effective, capable of
being manufactured in commercial quantities at an economical cost, approved by
appropriate regulatory authorities, accepted for coverage and reimbursement by
third party payers or successfully marketed in quantities sufficient to generate
operating revenue. Failure of any of the Company's product candidates to
successfully complete any of the steps necessary for their successful
commercialization would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business."
 
    DEVELOPMENT STAGE COMPANY; HISTORY OF SIGNIFICANT LOSSES; ANTICIPATED FUTURE
LOSSES; ACCOUNTANT'S EXPLANATORY PARAGRAPH REGARDING THE COMPANY'S ABILITY TO
CONTINUE AS A GOING CONCERN.  The Company is in the development stage and, as
such, has generated only limited revenue and has incurred significant operating
losses, including operating losses of $1,146,000, $1,245,000 and $596,000 for
the years ended December 31, 1995 and 1996 and the nine months ended September
30, 1997, respectively. As of September 30, 1997, the Company had an accumulated
deficit of $4,125,000. The Company expects to incur operating losses and
negative cash flow for the next several years and that its losses will increase
as the Company expands its research and development activities. The likelihood
of the Company's success must be considered in light of the problems, delays,
expenses and difficulties frequently encountered by enterprises in the early
stage of development, many of which may be beyond the Company's control. These
include, but are not limited to, unanticipated problems relating to product
development, preclinical and clinical testing, the obtainment of regulatory
approvals for the manufacture and sale of products, competition, manufacturing,
marketing, and the political, economic and regulatory problems associated with
engaging in business in India and other countries. These and other problems may
result in additional costs and expenses that exceed current estimates. There can
be no assurance that the Company will ever achieve significantly increased
revenues or profitable operations. In addition, the Company's independent
auditors have included an explanatory paragraph in their report stating that the
Company's accumulated deficit and its dependence, to date, upon advances and
loans from stockholders raise substantial doubts about the Company's ability to
continue as a going concern. The Offering is an integral part of the Company's
plan to continue as a going concern. See "Plan of Operation" and Combined
Financial Statements.
 
                                       8
<PAGE>
    SIGNIFICANT CAPITAL REQUIREMENTS; DEPENDENCE ON OFFERING PROCEEDS; WORKING
CAPITAL DEFICIT; NEED FOR ADDITIONAL FINANCING.  The Company's capital
requirements have been and will continue to be significant. To date, the Company
has been dependent primarily upon advances and loans from, or guaranteed by,
stockholders to fund its capital requirements. As of September 30, 1997, the
Company had a working capital deficit of $2,207,000, and it is dependent upon
the proceeds of the Offering to fund its continuing research and development and
other working capital requirements. The Company anticipates, based on its
currently proposed plans and assumptions relating to its operations (including
assumptions regarding the nature and extent of research and development required
in connection with the regulatory approval process, the timing of obtaining
regulatory approvals, if any, market acceptance, the competitive position of the
Company's products, and the ability of the Company to continue to secure
adequate manufacturing and distribution relationships) that the net proceeds of
the Offering will be sufficient to fund the Company's contemplated capital
requirements for at least 12 months following the consummation of the Offering.
In the event the Company's plans change or its assumptions change or prove to be
incorrect, the Company could be required to seek additional financing sooner
than currently anticipated. In addition, the Company will need to raise
substantial additional capital to fund its future operations. There can be no
assurance that additional financing will be available when needed on terms
acceptable to the Company, or at all. Any inability to obtain additional
financing when needed would have a material adverse effect upon the Company and
could prevent it from implementing its business strategy and require it to
significantly curtail its operations. In addition, if additional funds are
raised by issuing equity securities, dilution to then existing stockholders will
result and future investors may be granted rights superior to those of existing
stockholders. See "Use of Proceeds" and "Plan of Operation."
 
    DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS.  The Company's success
depends in large part on the continued services of its executive management team
and other key personnel. The Company's success also depends on its ability to
retain and attract highly skilled personnel, both in the United States and
India. There can be no assurance that the Company will be able to continue to
attract or retain such persons. In addition, the Company relies to a large
extent on scientific consultants to assist it in the drug discovery and
development process. The Company's success is substantially dependent upon the
efforts of these third parties and the continued availability of their services
to the Company. Many of the Company's arrangements with its consultants are
relatively short-term or are informal. There is, therefore, no assurance that
the Company will be able to retain or continue to retain such consultants or
other qualified consultants on commercially reasonable terms, or at all. In
addition, the time and resources devoted to the Company's business by its
consultants will generally be controlled by them and not by the Company, and
many of these consultants may have commitments to other entities that could
limit their availability to the Company. Some of these consultants may also
provide consulting services to companies that may be competitors of the Company.
The loss of existing executive management or key personnel, or the failure to
recruit additional highly skilled personnel, could significantly impede the
Company's attainment of its objectives and have a material adverse effect on the
Company's business, financial condition and result of operations. See
"Business--Consultants" and "Management."
 
    UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS.  The Company's success
depends in part on its ability to obtain patent protection for its products and
to preserve its trade secrets. The Company holds an exclusive license on the
United States patent relating to RA-11 and its use in treating degenerative
musculoskeletal diseases, including rheumatoid arthritis and osteoarthritis. The
Company also holds an exclusive license on two Indian patents, one of which
relates to the Company's proprietary plant extraction process and other to the
Company's proprietary process for formulating RA-11, both of which patents
expire in 2001. In addition, the Company has a pending United States patent
application related to BV-6. No assurance can be given that the Company's patent
applications will issue as patents, that any patents will provide the Company
with competitive advantages for its products or that they will not be
successfully challenged or circumvented by the Company's competitors. The
Company has not conducted an exhaustive patent search and no assurance can be
given that patents do not exist or could not be filed which would have an
adverse effect on the Company's ability to market its products. If other
companies were to
 
                                       9
<PAGE>
successfully bring legal actions against the Company claiming patent or other
intellectual property right infringements, then, in addition to any potential
liability for damages, the Company could be required to obtain a license in
order to continue to use the affected process or to manufacture or use the
affected product and, if enjoined by a court, the Company could be required to
cease using such process or product. There can be no assurance that the Company
would prevail in any such action or that any license required under any such
patent would be made available on acceptable terms, or at all. There is
significant litigation in the pharmaceutical industry regarding patent and other
intellectual property rights. If the Company becomes involved in such
litigation, it could consume a substantial portion of the Company's financial
and other resources, regardless of the outcome of such litigation. There can be
no assurance that the Company will have the financial or other resources
necessary to enforce or defend a patent infringement action. The Company also
relies on trade secrets and proprietary know-how which it seeks to protect, in
part, by confidentiality agreements with its employees and consultants. There
can be no assurance that these agreements will not be breached, that the Company
would have adequate remedies for any breach or that the Company's trade secrets
will not otherwise become known or independently developed by competitors. See
"Business--Patents, Licenses, and Proprietary Rights."
 
    At present, India only grants process patents for pharmaceutical products.
Although India is not a signatory of the Paris Convention, it is a member of the
World Trade Organization ("WTO"). As a signatory of WTO, India is required to
comply with its obligations under Trade-Related Aspects of Intellectual Property
Rights ("TRIPS"). TRIPS requires India to grant product patents for
pharmaceutical products after a certain transition period. During the transition
period, participating countries must establish a means for filing patent
applications relating to pharmaceutical products and agricultural chemicals and
also grant exclusive marketing rights for certain periods. In response to claims
raised by other countries, WTO ruled that India has not been abiding by its
transition period commitments under TRIPS. As of the date of this Prospectus, it
is expected that India will appeal the WTO decision. In addition, as an
aftermath of the Convention on Biological Diversity, India is planning to enact
a law on national bio-diversity. This law may place restrictions and/or
conditions for obtaining patents or other intellectual property relating to
biological material or products derived therefrom. See "Business--Patents,
Licenses and Proprietary Rights."
 
    NO ASSURANCE OF REGULATORY APPROVALS.  The Company's research, preclinical
development, clinical trials, and manufacturing and marketing of its products in
the United States and other countries are subject to extensive regulation by
numerous governmental authorities including, but not limited to, the FDA. The
Company has no products approved by the FDA and does not expect to achieve
profitable operations until products receive FDA approval, are commercialized
successfully, and become eligible for reimbursement by third party payers. Any
potential therapeutic product developed by the Company will be subject to
rigorous preclinical and clinical testing and approval pursuant to regulations
administered by the FDA and comparable agencies in other countries. The approval
process for the Company's drug candidates is lengthy and is likely to involve
significant expenditures. No assurance can be made that the Company will be able
to file any NDAs or that any such filings will result in FDA approval.
Furthermore, the Company cannot predict with any degree of certainty when it
might be in a position to file any NDA or the length of time involved between
the filing of an NDA and obtaining FDA approval, if at all. The cost to the
Company of conducting human clinical trials for any potential product can vary
dramatically based on a number of factors, including the order and timing of
clinical indications pursued and the extent of development and financial
support, if any, from corporate partners. The Company may have difficulty
obtaining sufficient patient populations, clinicians or support to conduct its
clinical trials as planned and may have to expend substantial additional funds
to obtain access to such resources, or delay or modify its plans significantly.
 
    The effect of government regulation may be to delay marketing of the
Company's proposed products for a considerable period of time, to impose costly
procedures upon the Company's activities and to furnish a competitive advantage
to companies that compete with the Company. There can be no assurance that
 
                                       10
<PAGE>
FDA or other regulatory authority approval for any product candidates developed
by the Company will be granted on a timely basis or at all. Any delay in
obtaining or any failure to obtain such approvals would materially and adversely
affect the marketing of the Company's drug candidates and the Company's
business, financial position and results of operations. In addition, legislation
may be enacted in the future which might adversely affect the Company's ability
to develop, manufacture or market its drug candidates. Any FDA approvals that
may be granted will be subject to continual review, and later discovery of
previously unknown problems may result in withdrawal of products from marketing.
Moreover, if and when such approval is obtained, the marketing and manufacture
of the Company's products would remain subject to extensive regulatory
requirements administered by the FDA and other regulatory bodies. Failure to
comply with these regulatory requirements could, among other things, result in
fines, suspensions or withdrawal of regulatory approvals, operating restrictions
and criminal prosecution. The Company intends, either on its own or in
collaboration with others, to market its products in major markets outside of
the United States. There can be no assurance that the Company will be successful
in establishing marketing relationships, conducting clinical testing in foreign
countries or obtaining required foreign regulatory approvals in a timely manner,
if at all. To market its products abroad, the Company must comply with numerous
and varying foreign regulatory requirements implemented by foreign health
authorities, governing, among other things, the design and conduct of clinical
trials, pricing regulations and marketing approval. The approval procedure may
vary among countries and can involve, for example, additional testing, and the
time required to obtain approval may differ from the time required to obtain FDA
approval. The foreign regulatory approval process includes all of the risks
associated with obtaining FDA approval. However, approval by the FDA of any drug
candidate does not ensure approval by the regulatory agencies of other
countries. See "Business--The Regulatory Approval Process" and "--Products and
Product Candidates."
 
    OPERATIONS CONDUCTED IN INDIA AND DEPENDENCE ON POLITICAL AND ECONOMIC
STABILITY OF INDIA.  Substantially all the Company's research and development
operations are currently conducted in India. To effectively manage its
operations in India, the Company requires, and will continue to require, the
engagement of persons with appropriate managerial skills and the implementation
of an effective supervisory program which will include a continual and current
flow of reliable information to the Company's officers in the United States and
frequent reports from, and visits to, its operations in India. Additional
administrative costs and greater security and operational risks, accordingly,
will be incurred than if the operations were conducted solely in the United
States. No assurance can be given that persons with the required managerial
skills can continue to be located and employed by the Company in India or that
an effective supervisory program can be maintained. Furthermore, the Company's
operations are, and will be, dependent on the political and economic stability
of India, as well as its laws, rules and regulations, particularly with respect
to licenses, permits, government controls, investments and conduct of operations
by foreign-owned entities, patents and other intellectual property protections,
taxes, customs, trade restrictions and exchange and currency controls. These
considerations may also apply to each of the individual states within India in
which the Company conducts or may conduct its operations.
 
    INABILITY TO REPATRIATE CERTAIN FUNDS.  Foreign investments in India are
subject to regulation under the Foreign Exchange Regulation Act, 1973. Under
existing Indian law, foreign investments in Indian companies can either be made
on a repatriation or non-repatriation basis. Investments made on a repatriation
basis permit repatriation out of India of the full capital amount invested,
together with interest, dividends and other amounts earned thereon. Investments
made on a non-repatriation basis do not permit repatriation out of India of any
of the capital amount invested. Interest, dividends and other income earned on
the capital amount, however, are currently repatriable out of India. Foreign
investments made on a repatriation basis require prior approval of the Foreign
Investment Promotion Board ("FIPB"), Government of India and Reserve Bank of
India ("RBI"). Investments made on a non-repatriation basis require no
governmental approval if made by non-resident Indians or overseas corporate
bodies owned at least 60% by nonresident Indians (collectively, "NRIs").
However, these investments are required to be declared in a filing made with the
RBI. Prior to the Offering, the Company has been considered an NRI.
 
                                       11
<PAGE>
As of September 30, 1997, an aggregate of approximately $688,000 had been
provided by the Company to fund the Company's operations in India, approximately
$268,000 of which was provided to Bio-Ved, and was registered or is being
registered, as a contribution to Bio-Ved's capital on a non-repatriation basis.
Since these funds have been invested on a non-repatriation basis, they cannot be
repatriated from India. The Company has submitted an application to the FIPB to
permit future investment in Bio-Ved on a repatriation basis. There can be no
assurance that the Company's application will be approved. See "Plan of
Operation."
 
    DEPENDENCE ON SOURCES OF SUPPLY.  The plant materials from which the
Company's products are being developed are currently located primarily in India.
The ability of the Company to secure an adequate supply of cultivated plant
materials will be affected by factors such as location, seasonality and weather.
Plant materials used in the production of RA-11 are purchased from one supplier,
Kancor Flavours & Extracts Pvt. Ltd. ("Kancor"), a supplier of plant extracts
located in India. Although the Company has entered into a supply agreement with
Kancor, there can be no assurance that this supplier will continue to be able to
supply the Company with all of the Company's requirements. The Company is also
dependent on Kancor and another supplier for plant materials used in connection
with the Company's other phyto-pharmaceutical research and development
activities. In addition, a continued source of plant supply is subject to the
risks inherent in international trade. Those risks include unexpected changes in
regulatory requirements, exchange rates, tariffs and barriers, difficulties in
coordinating and managing foreign operations, potentially adverse tax
consequences and disruptions in the political and economic stability of India
and other regions in which the plants are grown. The Indian government presently
prohibits the export of certain plants, plant portions and their derivatives and
extracts. Although none of the Company's products or product candidates are
produced utilizing any of these plant materials, there can be no assurance that
the Indian government will not, in the future, prohibit the export of plant
materials used in the Company's products. There can be no assurance of a
continual source of supply of plant materials. Interruptions in supply or
material increases in the cost of the supply could have a material adverse
affect on the Company's business, financial condition and results of operations.
See "Business--Manufacturing and Supply."
 
    LIMITED MANUFACTURING CAPACITY.  The Company does not have the staff or
facilities necessary to manufacture its products on a commercial scale. The
Company has entered into a manufacturing agreement with a pharmaceutical company
located in India for the production of RA-11, and the Company will seek similar
manufacturing agreements as additional products are developed and
commercialized. SA-12 is manufactured under an arrangement with another
pharmaceutical company located in India, although no formal agreement has yet
been entered into with this manufacturer. Although the Company intends to
monitor production at its manufacturers' facilities to assure their compliance
with the Company's product specifications, the Company will be dependent upon
its manufacturers to, among other things, satisfy performance and quality
specifications and dedicate sufficient production capacity to meet scheduled
delivery times. There can be no assurance that any manufacturer will devote the
resources necessary to meet any demand for the Company's products. Failure or
delay by the Company's manufacturers in supplying products would adversely
affect the Company's ability to deliver products on a timely and competitive
basis. Moreover, to the extent the Company engages manufacturers to manufacture
products to be sold in the United States, such manufacturers must comply with
the FDA's current good manufacturing practice ("cGMP") regulations and pass
pre-approval inspections by the FDA and periodic cGMP inspections. In the
future, the Company may decide to manufacture certain of its proposed products
on its own. This will require extensive investment in facilities and equipment
and will require experienced personnel. There can be no assurance that the
Company will be able to obtain the funds or other resources necessary to
establish its own manufacturing capabilities. See "Business--The Regulatory
Approval Process" and "--Manufacturing and Supply."
 
    LIMITED MARKETING CAPABILITIES AND EXPERIENCE.  The Company currently has no
marketing or sales staff and does not have the resources necessary to undertake
extensive marketing activities. Achieving
 
                                       12
<PAGE>
market acceptance for the Company's products will require substantial marketing
efforts and the expenditure of significant funds to inform potential customers
of the perceived benefits of the Company's products and proposed products.
Accordingly, the Company currently intends to rely on others for the sale and
marketing of its products. RA-11 is currently being test-marketed in India under
a memorandum of understanding with Alembic Chemical Works Co. Limited
("Alembic"), an Indian pharmaceutical company. The test-marketing is scheduled
to conclude in March 1998, at which time, subject to satisfactory test results,
the parties contemplate entering into a marketing agreement. There can be no
assurance that the test-marketing will be successful or that, even if
successful, a marketing agreement will be entered into with Alembic. Effective
September 1997, the Company entered into a distribution agreement with MD
Pharmaceuticals Laboratories Ltd., a Singapore-based pharmaceutical company,
covering the sale and marketing of RA-11 in certain Pacific Rim countries. The
Company has also entered into a distribution agreement covering the sale and
marketing of SA-12 in India. The Company will continue to seek to market and
distribute its products through others pursuant to contractual arrangements,
such as distribution agreements, joint ventures or other strategic arrangements.
To the extent the Company relies on the efforts of others to market and
distribute its products, the Company will lose a degree of control over an
important aspect of its business. While the Company believes that third party
distributors with which it enters into distribution agreements will have an
economic motivation to commercialize the Company's products, the time and
resources devoted to these activities will generally be contributed and
controlled by such entities and not by the Company. A decline in the financial
prospects of particular distributors could have an adverse effect on the
Company. There can be no assurance that the Company will be able to maintain its
relationships with existing distributors or enter into additional distribution
arrangements or that any such arrangements will result in the successful
commercialization of any of the Company's products. See "Business--Business
Strategy" and "--Marketing."
 
    RISKS RELATING TO LICENSED OR PURCHASED TECHNOLOGIES.  The Company has
entered into license agreements pursuant to which it acquired exclusive
worldwide rights to RA-11. One agreement relates to India and the other
agreement relates to the rest of the world. However, the Company's licensor does
not have any patent rights relating to RA-11 outside of the United States and
India. The Company has also entered into a license agreement pursuant to which
it acquired the exclusive worldwide rights to IM-10. The Company's rights under
these agreements are dependent upon its paying royalties at agreed upon rates
and commencing marketing within agreed upon periods of time. Although the
Company is presently in compliance with its obligations under the agreements,
there can be no assurance that it will continue to be able to comply with such
obligations. The Company has also entered into an agreement pursuant to which it
has been assigned a United States patent application related to BV-6, in
exchange for royalties. Failure by the Company to comply with the terms of any
of these agreements could result in the forfeiture by the Company of the
technologies. Such forfeiture could have a material adverse effect upon the
Company's business, financial condition and results of operations. See
"Business--Patents, Licenses and Proprietary Rights."
 
    RAPID TECHNOLOGICAL CHANGE AND SUBSTANTIAL COMPETITION.  The pharmaceutical
industry is subject to rapid and substantial technological change. Technological
competition from pharmaceutical companies, biotechnology companies and
universities is intense and is expected to increase. Many of these entities have
significantly greater research and development capabilities, as well as
substantial marketing, manufacturing, financial and managerial resources, and
represent significant competition for the Company. Some of the major
pharmaceutical companies, as well as several smaller companies, are seeking to
develop pharmacological products from plant derivatives. There can be no
assurance that developments by others will not render the Company's products or
technologies noncompetitive or that the Company will be able to keep pace with
technological developments. In addition, competitors have developed or are in
the process of developing technologies that are, or in the future may be, the
basis for competitive products. Some of these products may have an entirely
different approach or means of accomplishing the desired therapeutic effect and
may be more effective and less costly than the products developed by the
Company.
 
                                       13
<PAGE>
Other forms of medical treatment may also offer competition to the Company's
products. There can be no assurance that the Company will be able to compete
successfully. See "Business--Competition."
 
    PRODUCT LIABILITY EXPOSURE.  The Company faces an inherent risk of exposure
to product liability claims in the event that the investigation or use of
products manufactured by the Company results in illness or injury. While the
Company will continue to attempt to take appropriate precautions, there can be
no assurance that it will avoid significant product liability exposure. The
Company currently has product liability insurance coverage in India, the only
country in which its products are currently being marketed. As its products
achieve wider-spread commercialization, the Company intends to seek product
liability insurance in amounts consistent with industry practice in the
countries in which its products are to be marketed. There can be no assurance
that the Company's current insurance coverage is adequate or that adequate
insurance coverage will be available at an acceptable cost, if at all. In the
event of a partially or completely uninsured successful claim against the
Company, the business and financial condition of the Company could be materially
adversely affected. See "Business--Product Liability."
 
    COMPLIANCE WITH ENVIRONMENTAL REGULATIONS.  In connection with the
performance of its research and development activities and the manufacturing of
materials for its clinical trials, the Company is subject to standards imposed
by India and, to the extent the Company conducts operations or maintains
facilities in the United States, the Company will be subject to United States
federal, state and local laws, rules, regulations and policies governing the
use, generation, manufacture, storage, air emission, effluent discharge,
handling and disposal of certain materials and wastes (which activities involve
the controlled handling and disposal of hazardous and regulated materials such
as tissue samples, live viruses and chemicals). Although the Company believes
that its safety procedures comply with applicable standards in India and, when
performed in the United States, will comply with standards prescribed by United
States federal, state and local regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. In
the event of such an accident, the Company could be held liable for the damages
that result and any such liability could exceed the resources of the Company.
Moreover, there can be no assurance that the Company will not be required to
incur significant costs to comply with environmental and health and safety
regulations in the future. See "Business--Other Government
Regulation--Environmental Regulation."
 
    UNCERTAINTY OF HEALTHCARE REIMBURSEMENT; PRICING.  In both domestic and
foreign markets, sales of the Company's products, if any, will be dependent in
part on coverage and reimbursement by third party payers, such as government and
private insurance plans. Third party payers are increasingly challenging the
prices charged for pharmaceutical products and services. There can be no
assurance that the Company's products will be considered cost effective, that
reimbursement will be available, or if available, that the payer's reimbursement
policies will not adversely affect the Company's ability to sell its products
with an appropriate return on its investment. See "Business--Other Government
Regulation--Coverage and Reimbursement by Third Party Payers."
 
    FOREIGN TRADE RISKS.  To date, all of the Company's sales have been made in
India and the Company intends to continue to rely on sales to foreign markets
for a significant portion of its revenues. If, and to the extent that, the
Company is able to successfully market its products in foreign markets, the
Company will become increasingly subject to the risks inherent in foreign trade,
including shipping delays, increased collection risks, trade restrictions,
export duties and tariffs, fluctuations in foreign currencies and international
political, regulatory and economic developments, all of which could have an
adverse effect on the Company's operating margins and results of operations and
exacerbate the risks inherent in the Company's business. While the Company
believes that the products it currently markets have all necessary governmental
clearances required for the importation and sale of such products in the foreign
countries in which its products are currently marketed, there can be no
assurance that this is actually the case or that governmental authorities in
such foreign countries will not, in the event of noncompliance, suspend
distribution of the Company's products. See "Business--Marketing."
 
                                       14
<PAGE>
    CONTROL BY EXISTING STOCKHOLDERS; POSSIBLE DEPRESSIVE EFFECT ON THE
COMPANY'S SECURITIES.  Immediately following the consummation of the Offering,
the Company's existing stockholders will, in the aggregate, beneficially own
approximately 69% of the outstanding Common Stock (including 553,427 shares
underlying currently exercisable options and warrants). As a result, the
Company's existing stockholders will be able to elect all of the Company's
directors, dissolve, merge or sell all of the Company's assets and otherwise
control the Company. Such concentration of control of the Company may also have
the effect of delaying, deferring or preventing a third party from acquiring
control of the Company, may discourage bids for the Company's Common Stock at a
premium over the market price and may adversely affect the market price of the
Common Stock. See "Principal Stockholders."
 
    POSSIBLE ADVERSE EFFECT OF INVESTIGATION BY SECURITIES AND EXCHANGE
COMMISSION OF REPRESENTATIVE CONCERNING COMPLIANCE WITH THE FEDERAL SECURITIES
LAWS.  The Securities and Exchange Commission (the "Commission") is conducting
an investigation concerning various aspects of the Representative's compliance
with the Federal securities laws. The Representative cannot predict whether this
investigation will ever result in any type of action against the Representative,
or, if so, whether any such action might have an adverse effect on the
Representative or the securities offered hereby. The Company has been advised
that the Representative intends to make a market in the securities following the
Offering. An unfavorable resolution of the Commission's investigation could have
the effect of limiting the Representative's ability to make a market in the
Company's securities, which could affect the liquidity or price of such
securities. See "Underwriting."
 
    IMMEDIATE AND SUBSTANTIAL DILUTION.  A purchaser in the Offering will
experience immediate and substantial dilution of approximately $4.60 per share
or 76.7% from the initial public offering price per share (based on an assumed
offering price of $6.00 per share, the midpoint of the anticipated range of the
initial public offering price per share). See "Dilution."
 
    BENEFITS OF THE OFFERING TO CURRENT STOCKHOLDERS.  Upon the consummation of
the Offering, the current stockholders of the Company will receive substantial
benefits, including the creation of a public trading market for their securities
and the corresponding facilitation of sales by such stockholders of their shares
of Common Stock in the secondary market (although most of such shares are
subject to 12-month "lock-up" agreements with the Representative and to certain
limitations on resale imposed upon officers, directors and affiliates of the
Company under the Federal securities laws), as well as an immediate increase in
net tangible book value of $1.98 per share to such stockholders based upon the
adjusted net tangible book value per share after the consummation of the
Offering and the application of the estimated net proceeds of the Offering
(based upon an assumed offering price of $6.00 per share, the midpoint of the
currently anticipated range of the initial public offering price per share). If,
at the time the existing stockholders are able to sell their shares of Common
Stock in the public market, the market price per share remains at the initial
public offering price, of which there can be no assurance, such stockholders
would realize an average gain of $4.96 per share on the sale of their existing
shares (again, based upon an assumed offering price of $6.00 per share). In
addition, the Company intends to use proceeds from the Offering to repay its
outstanding bank debt, all of which is personally guaranteed by Sanjeev and
Deepa Chitre, each a principal stockholder, director and officer of the Company,
and secured by collateral pledged by a trust for the benefit of their daughter.
This repayment will result in a benefit to such individuals, as their guarantees
and security will be released. See "Use of Proceeds," "Dilution," "Plan of
Operation--Liquidity and Capital Resources," "Principal Stockholders," "Certain
Transactions," "Shares Eligible for Future Sale" and "Underwriting."
 
    NO DIVIDENDS ANTICIPATED.  The Company has never paid any dividends on its
securities and does not anticipate the payment of dividends in the foreseeable
future. See "Description of Securities--Dividend Policy."
 
    ANTI-TAKEOVER PROVISIONS; POSSIBLE ADVERSE EFFECTS OF AUTHORIZATION OF
PREFERRED STOCK.  The Company's Certificate of Incorporation and By-Laws and
Delaware's General Corporation Law contain certain
 
                                       15
<PAGE>
provisions that could have the effect of making it more difficult for a third
party to acquire, or of discouraging a third party from attempting to acquire,
control of the Company. Such provisions could limit the price that certain
investors might be willing to pay in the future for shares of the Common Stock.
Certain of such provisions impose various procedural and other requirements
which could make it more difficult for stockholders to effect certain corporate
actions. Furthermore, the Company's Certificate of Incorporation authorizes the
issuance of up to 5,000,000 shares of preferred stock on terms which may be
fixed by the Company's Board of Directors without further stockholder action.
The terms of any series of preferred stock, which may include priority claims to
assets and dividends and special voting rights, redemption rights and terms and
liquidation preferences could adversely affect the rights of holders of the
Common Stock. The issuance of preferred stock could make the possible takeover
of the Company or the removal of management of the Company more difficult,
discourage hostile bids for control of the Company in which stockholders may
receive premiums for their shares of Common Stock or otherwise dilute the rights
of holders of Common Stock and the market price of the Common Stock. See
"Description of Securities."
 
    NO ASSURANCE OF PUBLIC MARKET; NEGOTIATED OFFERING PRICE; POSSIBLE
VOLATILITY OF MARKET PRICE OF COMMON STOCK.  Prior to the Offering, there has
been no public market for the Common Stock. There can be no assurance that any
trading market for the Common Stock will develop or that, if any such market
develops, it will be sustained. The initial public offering price of the Common
Stock will be established by negotiation between the Company and the
Representative and may not necessarily bear any relationship to the Company's
book value, assets, past operating results, financial condition or other
established criteria of value. The market price of the Common Stock following
the Offering may be highly volatile as has been the case with the securities of
other development stage companies and many emerging companies. Factors such as
the Company's operating results, announcements by the Company or its competitors
of technological innovations or new products, and various factors affecting the
pharmaceutical industry generally, may have a significant impact on the market
price of the Company's securities. In addition, in recent years, the stock
market has experienced a high level of price and volume volatility and market
prices for the stock of many companies, particularly of small and emerging
growth companies, the common stock of which trade in the over-the-counter
market, have experienced wide price fluctuations which have not necessarily been
related to the operating performance of such companies. Accordingly, purchasers
of the Common Stock may experience difficulty selling or otherwise disposing of
their Common Stock. See "Underwriting."
 
    POSSIBLE NASDAQ DELISTING; LOW STOCK PRICE.  It is currently anticipated
that the Common Stock will be eligible for listing on Nasdaq upon the
consummation of the Offering. However, to maintain eligibility for trading on
Nasdaq following the Offering, the Company will be required to, among other
things, maintain net tangible assets of at least $2,000,000 and a minimum bid
price of $1.00 per share and adhere to certain corporate governance provisions.
If, in the future, the Company should fail any of these maintenance tests or
requirements, the Common Stock could be delisted from trading on Nasdaq and
trading, if any, in the Common Stock would thereafter be conducted in the
non-Nasdaq over-the-counter market. The effects of delisting include the limited
release of the market prices of the Company's securities and limited news
coverage of the Company. Delisting may restrict investors' interest in the
Company's securities and materially adversely affect the trading market and
prices for such securities and the Company's ability to issue additional
securities or to secure additional financing. In addition to the risk of
volatile stock prices and possible delisting, low price stocks are subject to
the additional risks of federal and state regulatory requirements and the
potential loss of effective trading markets. In particular, if the Common Stock
were delisted from trading on Nasdaq and the trading price of the Common Stock
was less than $5.00 per share, the Common Stock could be subject to Rule 15g-9
under the Exchange Act which, among other things, requires that broker/dealers
satisfy special sales practice requirements, including making individualized
written suitability determinations and receiving purchasers' written consent,
prior to any transaction. If the Company's securities were also deemed penny
stocks under the Securities Enforcement and Penny Stock Reform Act of 1990, this
would require additional disclosure in connection with trades in the Company's
securities, including the delivery of a disclosure schedule explaining the
nature
 
                                       16
<PAGE>
and risks of the penny stock market. Such requirements could severely limit the
liquidity of the Company's securities and the ability of purchasers in the
Offering to sell their securities in the secondary market.
 
    FUTURE SALES OF RESTRICTED SECURITIES; REGISTRATION RIGHTS.  Upon the
consummation of the Offering, the Company will have 3,459,702 shares of Common
Stock outstanding, of which the 1,250,000 shares of Common Stock offered hereby
will be freely tradable by persons other than affiliates of the Company, without
restriction or further registration under the Securities Act of 1933, as amended
(the "Securities Act"). The remaining 2,209,702 shares of Common Stock (the
"Restricted Shares") outstanding were sold by the Company in reliance on
exemptions from the registration requirements of the Securities Act and are
"restricted securities" as defined in Rule 144 promulgated under the Securities
Act and may not be sold in the absence of registration under the Securities Act
unless an exemption therefrom, including an exemption afforded by Rule 144, is
available. Under Rule 144 (and subject to the conditions thereof), 619,850 of
the Restricted Shares are eligible for sale as of the date of this Prospectus,
1,380,144 of the Restricted Shares will become eligible for sale beginning 90
days after the date of this Prospectus, and substantially all of the remaining
209,708 Restricted Shares will become eligible for sale as of October 31, 1998.
The Company's officers, directors and existing stockholders have entered into
agreements which prohibit them from selling any securities of the Company
without the prior written consent of the Representative for a period of 12
months following the date of this Prospectus. The holders of the
Representative's Warrants and October 1997 Warrants will also be entitled to
certain registration rights with respect to such securities. The sale of a
substantial number of shares of Common Stock or the availability of Common Stock
for sale could adversely affect the market price of the Common Stock prevailing
from time to time. See "Shares Eligible for Future Sale" and "Underwriting."
 
    EFFECT OF PREVIOUSLY ISSUED OPTIONS AND WARRANTS AND OF THE REPRESENTATIVE'S
WARRANTS ON STOCK PRICE. The Company has reserved from the authorized, but
unissued, Common Stock 710,970 shares of Common Stock for issuance upon exercise
of outstanding options and warrants (390,970 of which have exercise prices of
$4.00 or less) and 182,986 shares of Common Stock for issuance upon exercise of
options available for future grant under the Option Plan. In addition, upon the
consummation of the Offering, the Company will sell to the Representative, for
nominal consideration, the Representative's Warrants to purchase an aggregate of
125,000 shares of Common Stock at a price per share equal to 135% of the initial
offering price per share. The existence of these options and warrants may prove
to be a hindrance to future financings, since the holders of such securities may
be expected to exercise them at a time when the Company would otherwise be able
to obtain additional equity capital on terms more favorable to the Company. In
addition, the holders of the Representative's Warrants will have certain
registration rights, and the sale of the shares issuable upon exercise of such
securities or the availability of such shares for sale could adversely affect
the market price of the Common Stock. See "Description of Securities" and
"Underwriting."
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
    Certain statements contained or incorporated by reference in this
Prospectus, including without limitation, statements containing the words
"believes," "anticipates," "intends," "expects," "plans" and words of similar
import, constitute "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. Such forward-looking
statements involve known and unknown risks, uncertainties, assumptions and other
factors which may cause the actual results, performance or achievements of the
Company, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements. Such factors include, among others, the risks
identified above under "Risk Factors." Given these uncertainties, prospective
investors are cautioned not to place undue reliance on such forward-looking
statements. The Company disclaims any obligation to update any such factors or

                                USE OF PROCEEDS
 
    The net proceeds to be received by the Company from the sale of the
1,250,000 shares of Common Stock offered hereby are estimated to be
approximately $6,120,000 (approximately $7,098,750 if the Representative's
over-allotment option is exercised in full), assuming an initial public offering
price of $6.00 per share (the midpoint of the currently anticipated range of the
initial public offering price) and after deducting underwriting discounts and
estimated offering expenses. The Company expects to use the net proceeds as
follows:

(1) Includes estimated costs and expenses relating to (i) filing an IND and, if
    IND approval is obtained, commencing a Phase II clinical trial in the United
    States and a Phase III clinical trial in India, all relating to RA-11; (ii)
    continued preclinical testing of IM-10, BV-6 and HP-11 and, subject to
    obtaining successful preclinical results, the commencement of clinical
    trials for IM-10 and HP-11 in India; and (iii) establishing and equipping
    additional laboratory facilities in India. Also includes $140,000
    representing accounts payable related to research and development
    activities. See "Business--Products and Product Candidates" and
    "--Facilities."
 
(2) Includes $500,000 aggregate principal amount borrowed at various times from
    November 1996 through September 1997 from the Atlantic Bank of New York
    under three-month term notes at prime plus 2% per annum. The notes have been
    consolidated and are presently due on February 2, 1998. Also includes
    $150,000 principal amount borrowed from two individual investors in March
    and July 1996 (plus accrued interest at prime plus 2% per annum estimated
    through the anticipated consummation of the Offering). The proceeds of all
    such loans were used for research and development and marketing. See "Plan
    of Operation--Liquidity and Capital Resources."
 
(3) Represents manufacturing expenditures relating to RA-11 and SA-12 for the
    build-up of product inventory and marketing expenditures relating to RA-11
    and SA-12 for promotional materials and samples, medical symposia, product
    educational programs and various related activities. See
    "Business--Marketing."
 
(4) Working capital will be used for general corporate purposes, including
    approximately $330,000 in aggregate annual base compensation for the
    Company's three executive officers. Also includes costs for (i) seeking
    collaborative arrangements with pharmaceutical companies, (ii) establishing
    and enhancing management and information systems needed to monitor, control
    and coordinate the Company's activities and (iii) patent and trademark
    filings. See "Plan of Operation" and "Management."
 
    The foregoing represents the Company's best estimate of the allocation of
the net proceeds of the Offering during the next 12 months. This estimate is
based on certain assumptions, including that development, testing and regulatory
requirements relating to the Company's products can be completed at budgeted
costs and that commercial sales of the Company's products will increase
significantly from results previously achieved by the Company. Projected
expenditures are estimates or approximations only. Future events, including the
problems, delays, expenses, difficulties and complications frequently
encountered by companies in an early stage of development, changes in economic,
regulatory or competitive conditions or
 
                                       18
<PAGE>
in the Company's planned business, and the success or lack thereof of the
Company's development and sales and marketing efforts during the 12-month period
following the consummation of the Offering may make shifts in the allocation of
funds and curtailment of certain planned expenditures necessary or desirable.
Any such shifts will be at the discretion of the Company. See "Plan of
Operation."
 
    If the Representative exercises the over-allotment option in full, the
Company will realize additional net proceeds of $978,750 (assuming an initial
public offering price of $6.00 per share). Such additional proceeds are expected
to be added to the Company's working capital.
 
    Proceeds not immediately required for the purposes described above will be
invested principally in short-term interest bearing securities, money market
funds, certificates of deposit or direct or guaranteed obligations of the United
States government.
 
                                    DILUTION
 
    The difference between the initial public offering price per share of Common
Stock and the net tangible book value per share of Common Stock after the
Offering constitutes the dilution to investors in the Offering. Net tangible
book value per share on any given date is determined by dividing the net
tangible book value of the Company (total tangible assets less total
liabilities) on such date by the number of then outstanding shares of Common
Stock.
 
    At September 30, 1997, net negative tangible book value of the Company was
$(2,098,000), or $(1.05) per share. After giving pro forma effect to the Note
Conversion (including the conversion of interest accrued in October 1997), the
pro forma net negative tangible book value of the Company at September 30, 1997
would have been $(1,271,000), or $(.58) per share. After also giving retroactive
effect to the sale of the 1,250,000 shares of Common Stock offered hereby at an
assumed price of $6.00 per share (the midpoint of the currently anticipated
range of the initial public offering price) and the receipt and anticipated
application of the estimated net proceeds therefrom, the as adjusted net
tangible book value of the Company at September 30, 1997 would have been
$4,849,000 or $1.40 per share, representing an immediate increase in net
tangible book value of $1.98 per share to existing stockholders and an immediate
dilution of $4.60 (76.7%) per share to investors in the Offering.
 
    The following table illustrates the foregoing information with respect to
dilution to new investors on a per share basis:

    The foregoing table assumes no exercise of the Representative's
over-allotment option. If such option is exercised in full, the new investors
will have paid $8,625,000 (based on an assumed price of $6.00 per share, the
midpoint of the currently anticipated range of the initial public offering
price) for 1,437,500 shares of Common Stock, representing approximately 78.9% of
the total consideration for 39.4% of the total number of shares outstanding. In
addition, computations set forth in the above table exclude an aggregate of
710,970 shares of Common Stock reserved for issuance upon the exercise of
currently outstanding stock options and warrants, at various prices ranging from
$.34 per share to 130% of the initial public offering price per share, and
125,000 shares of Common Stock reserved for issuance upon the exercise of the
Representative's Warrants. See "Management--Stock Options," "Description of

                               PLAN OF OPERATION
 
HISTORY
 
    The Company was organized in January 1993. The Company's initial efforts
were focused on assembling a high quality and diverse network of scientists and
institutions in the United States and India to support the Company's drug
discovery and development efforts in India. In 1994 and 1995, the Company
entered into license agreements pursuant to which it acquired exclusive
worldwide rights to RA-11 and IM-10, respectively. In 1995, the Company also
obtained exclusive licenses under a United States patent and two Indian patents
related to RA-11 and acquired SA-12 and a pending United States patent
application related to BV-6. The Company's research efforts led to the
identification of HP-11. The Company has been engaged in the development and
testing of all of these products. The Company has also devoted significant
resources to securing intellectual property protection with respect to certain
of these products. The Company began selling SA-12 through a distributor in
India in early 1997. In October 1997, the Company launched a test-marketing
program of RA-11 in India.
 
    The Company's initial activities in India were conducted through a liaison
office in India. In November 1995, Bio-Ved was formed to facilitate the
Company's activities in India. Since the formation of Bio-Ved, substantially all
of the Company's India-based activities have been conducted by Bio-Ved under the
direction of the Company. As of September 30, 1997, the Company had provided an
aggregate of approximately $688,000 in connection with its operations in India.
Of such amount, approximately $268,000 was provided to Bio-Ved, and was
registered or is being registered, as a contribution to Bio-Ved's capital on a
non-repatriation basis. The Company expects to continue to devote significant
financial and other resources to its research and development and other
operations. See "--Research and Development."
 
    As a development stage company, the Company has generated only limited
revenue and has incurred significant operating losses since its inception,
including operating losses of $1,146,000, $1,245,000 and $596,000 for the years
ended December 31, 1995 and 1996 and the nine months ended September 30, 1997,
respectively. As a result, as of September 30, 1997, the Company had an
accumulated deficit of $4,125,000. The Company expects to incur operating losses
and negative cash flow for the next several years and that its losses will
increase as the Company expands its research and development activities. In
addition, the Company's independent auditors have included an explanatory
paragraph in their report stating that the Company's accumulated deficit and its
dependence, to date, upon advances and loans from stockholders raise substantial
doubts about the Company's ability to continue as a going concern. The Offering
is an integral part of the Company's plan to continue as a going concern. See
Combined Financial Statements.
 
PLAN OF OPERATION
 
    During the 12-month period following the Offering, the Company intends to
focus its research and development efforts (i) with respect to RA-11, on filing
an IND with the FDA, and if IND approval is obtained, commencing a Phase II
clinical trial in the United States and a Phase III clinical trial in India,
(ii) with respect to IM-10 and HP-11, on continued preclinical testing in India
and the United States and, subject to obtaining successful results, the
commencement of clinical trials in India, and (iii) with respect to BV-6, on
continued preclinical studies in the United States. The proceeds of the Offering
will not be sufficient to complete development efforts of any of these proposed
products and the Company will require substantial additional financing to
further development efforts in these areas.
 
    During such 12-month period, the Company will also devote efforts to (i)
seeking collaborative arrangements with pharmaceutical companies which could
assist in product development as well as with manufacturing and marketing
activities, (ii) establishing and enhancing management and information
 
                                       24
<PAGE>
systems needed to monitor, control and coordinate the Company's activities and
(iii) securing additional patent and trademark protection.
 
    During such 12-month period, the Company expects to hire additional
employees in the area of research and development in the United States and
India, including research and development directors in both countries, and
phytochemists, ethnobotanists and other scientists in India. The Company also
intends to hire additional personnel for manufacturing and marketing activities.
See "Business."
 
RESEARCH AND DEVELOPMENT
 
    The goal of the Company's research and development activities is to conduct
research at a level that is acceptable to the FDA and other regulatory bodies,
as well as global markets. With the exception of BV-6, substantially all of the
Company's research and development activities are presently conducted through
Bio-Ved in India. The Company funds most of Bio-Ved's research activities and
all ownership rights automatically vest in the Company. Bio-Ved currently has
three operational laboratories integrated at one site in India. These
laboratories are staffed with Bio-Ved's research and development scientists and
are also utilized by scientific consultants in connection with the Company's
activities. The Plant Screening Laboratory has the responsibility for analyzing
potential plant candidates and for the fractionation/ standardization of new and
existing products. The Formulations Laboratory has the primary mission of
developing the appropriate dosage forms for phyto-pharmaceuticals and quality
control and analytical procedures. The Animal Pharmacology Laboratory has the
responsibility for the study of pharmacological activity and mechanisms of
actions and for monitoring biochemical reactions in animal models. The Company
will seek to expand these laboratories to include other chemistry and
pharmacology activities. The Company, either directly or through Bio-Ved, also
has relationships with scientific institutions in India and elsewhere with whom
the Company has engaged and expects to continue to engage in joint research
activities.
 
    Research and development activities with respect to BV-6 are currently
conducted at Emory University in the United States.
 
    During the years ended December 31, 1995 and 1996 and the nine months ended
September 30, 1997, the Company expended $318,000, $401,000 and $228,000,
respectively, in connection with its research and development activities. In
September 1996, the Company received a Small Business Innovative Research
("SBIR") grant in the amount of $100,000 from the National Institutes of Health
in connection with its BV-6 research activities. In April 1997, the Company
applied for an additional SBIR grant relating to its BV-6 research in the amount
of $750,000.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's capital requirements have been and will continue to be
significant. As of September 30, 1997, the Company had a working capital deficit
and accumulated deficit of $2,207,000 and $4,125,000, respectively, and the
Company is dependent upon the proceeds of the Offering to fund its continuing
research and development and other working capital requirements. The Company
anticipates, based on its currently proposed plans and assumptions relating to
its operations (including assumptions regarding the nature and extent of
research and development required in connection with the regulatory approval
process, the timing of obtaining regulatory approvals, if any, market
acceptance, the competitive position of the Company's products, and the ability
of the Company to secure adequate manufacturing and distribution relationships)
that the net proceeds of Offering will be sufficient to fund the Company's
contemplated capital requirements for at least 12 months following the
consummation of the Offering. In the event the Company's plans change or its
assumptions change or prove to be incorrect, the Company could be required to
seek additional financing sooner than currently anticipated. In addition, the
Company
 
                                       25
<PAGE>
will need to raise substantial additional capital to fund its future operations.
There can be no assurance that additional financing will be available when
needed on terms acceptable to the Company, or at all.
 
    The Company's operations have been funded primarily through a combination of
approximately $1,500,000 in equity and $1,600,000 in debt. In addition, the
Company has received an aggregate of $100,000 through SBIR grant funding from
the National Institutes of Health. See "Business--Products and Product
Candidates--BV-6."
 
    At various times from June 1993 through February 1995 the Company sold an
aggregate of 412,866 shares of Common Stock to a limited number of investors for
an aggregate purchase price of $1,465,000. These shares were sold at varying
valuations ranging from $.55 to $6.00 per share. In addition, in connection with
the Note Conversion, effective October 31, 1997, $700,000 principal amount of,
and $138,830 in accrued interest on, certain of the Company's then outstanding
notes were converted into Common Stock at the rate of $4.00 per share.
 
    As of the date of this Prospectus, the Company has $879,700 in principal
amount of loan obligations outstanding, all of which is currently due and
payable on demand, except for $229,700, which is scheduled to become due and
payable on demand commencing one year following the consummation of the
Offering. Other than such $229,700, all presently outstanding loans are
anticipated to be repaid from the proceeds of the Offering.
 
    The approximately $1,600,000 of debt incurred by the Company since its
inception includes the following:
 
    In October 1994, the Company borrowed $250,000 from Fred Kassner, a
principal stockholder of the Company, under a two-year convertible promissory
note bearing interest at prime plus 2% per annum convertible into 61,050 shares
of Common Stock. In April 1996, the Company borrowed an additional $250,000 from
this stockholder under a 90-day promissory note bearing interest at prime plus
2% per annum. In connection with the April 1996 loan, Mr. Kassner was granted
two-year warrants to purchase up to 125,000 shares of Common Stock at 130% of
the initial public offering price per share. Effective October 31, 1997,
pursuant to the Note Conversion, all principal and accrued interest owing under
these notes (a total of $619,868) were converted by Mr. Kassner into 154,967
shares of Common Stock at the rate of $4.00 per share. In connection with this
transaction, Mr. Kassner was also granted October 1997 Warrants to purchase up
to 45,000 shares of Common Stock at the initial public offering price per share.
See "Certain Transactions."
 
    At various times from January 1996 through July 1997, the Company borrowed
an aggregate principal amount of $204,700 from Sanjeev Chitre, Chairman of the
Board of Directors and a principal stockholder of the Company, under a
promissory note bearing interest at prime plus 2% per annum payable semi-
annually. Originally, the note was to become due on demand, in stages, at
various times from January 1997 to July 1998. In December 1997, the terms of the
loan were revised to provide that no amounts would become due and payable
thereunder until one year following the consummation of the Offering. The
Company has allocated no proceeds of the Offering to repayment of the loan. See
"Certain Transactions."
 
    In January 1996, the Company borrowed $25,000 from Irwin Rosenthal, the
Secretary of the Company and husband of a director of the Company, under a
promissory note bearing interest at prime plus 2% per annum. Originally, the
note was to become due on demand commencing January 1997. Mr. Rosenthal was a
director of the Company at the time of the loan. In December 1997, the terms of
the loan were revised to provide that no amounts would become due and payable
thereunder until one year following the consummation of the Offering. The
Company has allocated no proceeds of the Offering to repayment of this loan. See
"Certain Transactions."
 
                                       26
<PAGE>
    In March 1996, the Company borrowed $50,000 from a stockholder and former
director of the Company under a promissory note bearing interest at prime plus
2% per annum. The note is currently due and payable on demand and is anticipated
to be repaid out of the proceeds of the Offering. In connection with the loan,
the Company granted the individual two-year warrants to purchase up to 25,000
shares of Common Stock at 130% of the initial public offering price per share.
 
    In each of March 1996 and August 1997, the Company borrowed $100,000 from
Michael Splinter, who subsequently became a director of the Company, and his
wife, under promissory notes each bearing interest at prime plus 2% per annum.
In connection with the loans, these individuals were granted two-year warrants
to purchase up to 100,000 shares of Common Stock at 130% of the initial public
offering price per share. Effective October 31, 1997, pursuant to the Note
Conversion, all principal and accrued interest owing under these notes were
converted by the holder into 54,741 shares of Common Stock at the rate of
$4.00 per share. See "Certain Transactions."
 
    In July 1996, the Company borrowed $100,000 from an unrelated individual
under a promissory note bearing interest at prime plus 2% per annum. The note is
currently due and payable on demand and is anticipated to be repaid out of the
proceeds of the Offering. See "Use of Proceeds."
 
    At various times from November 1996 through September 1997, the Company
borrowed an aggregate principal amount of $500,000 from the Atlantic Bank of New
York ("Atlantic Bank") under three-month term notes bearing interest at Atlantic
Bank's prime rate plus 2% per annum, payable monthly. The notes have been
consolidated and are presently due on February 2, 1998. The Atlantic Bank loan
is guaranteed by Sanjeev and Deepa Chitre and secured by a pledge of common
stock of another company, which stock is owned by the Avantika Sanjeev Chitre
Irrevocable Trust, dated July 8, 1991, Bruce W. McRoy, trustee (the "Avantika
Trust"), a trust for the benefit of Sanjeev and Deepa Chitre's minor daughter.

GENERAL
 
    The Company is engaged primarily in the discovery, development, clinical
testing and marketing of proprietary plant-based pharmaceuticals
(phyto-pharmaceuticals) for the treatment of chronic, difficult-to-treat human
diseases. The Company currently has three phyto-pharmaceutical products in
various stages of clinical and preclinical development. RA-11, the Company's
lead phyto-pharmaceutical, is currently being test-marketed in India for the
treatment of arthritis; IM-10, which is undergoing preclinical animal
pharmacology testing in India, has been indicated for the stimulation and
restoration of bone marrow and the immune system in cancer patients being
treated with chemotherapy; and HP-11, an early-stage product candidate, is
undergoing laboratory testing in India for the treatment of hepatitis. The
Company has an exclusive license under a United States patent relating to RA-11
and its use in treating degenerative musculoskelatal diseases. In addition, the
Company has a patent application pending relating to BV-6, a pharmaceutical
derived from a single animal cell component, which is undergoing early
pharmacological studies at Emory University for the treatment of degenerative
diseases of the central nervous system.
 
    A key element of the Company's strategy is to apply the principles of
Ayurveda, an ancient science native to India, to reduce the time and costs
associated with the drug discovery process. Generations of Ayurveda scholars
have studied and documented the uses and efficacy of specific plants as
medicinal therapies over a period of several hundreds of years. Their findings,
preserved and detailed in Ayurvedic literature, provide valuable information for
modern day scientists. Through the study of Ayurveda, the Company's scientific
team seeks to rapidly identify plants, or combinations of plants, that have been
successfully used to treat symptoms and ailments characteristic of the diseases
targeted by the Company. In addition, because Ayurvedic literature has also
documented the safety of over 300 plant extracts for human use, once an
Ayurvedic plant candidate has been identified by the Company's researchers, they
are, in many instances, able to conduct early development activities in
parallel, rather than sequentially, when determining the candidate's safety and
efficacy. The Company believes that focusing its screening process on plants
whose safety and efficacy in medicinal use have been documented in Ayurvedic
literature will result in faster and more effective screening methods for the
discovery of new phyto-pharmaceuticals. The Company further believes that, based
on their long histories of safe use, these phyto-pharmaceuticals will have a
greater potential for safety and, as a result, may achieve more rapid regulatory
approval.
 
    The Company's research and development activities are primarily conducted by
the Company's Indian subsidiary at laboratories located in Pune, India, which
are staffed with 15 full time employees and 12 consultants. There, the Company's
India-based scientists are able to study the Ayurvedic literature (primarily
written in the ancient Sanskrit language) to accelerate the plant screening
process. In addition, by conducting operations in India, the Company is able to
access highly skilled scientific talent and other resources at an estimated
one-tenth of the cost of comparable labor and resources in the United States.
Although the Company's clinical trials to date have only been conducted in
India, they have been administered in accordance with protocols designed to be
consistent with the standards of the United States Food and Drug Administration
(the "FDA") and in laboratories that operate in accordance with FDA Good
Laboratory Practices ("GLP") guidelines. In addition, the Company's proprietary
plant extraction process is conducted for it by a third-party Indian supplier
with an ISO-9000 (a worldwide industry manufacturing standard) certification.
The Company has thus established, and continues to enhance, a network
infrastructure in India designed to identify phyto-pharmaceuticals through an
accelerated process and in a low-cost, high quality environment.
 
    The Company is in the development stage and does not anticipate completing
clinical trials or filing a new drug application ("NDA") with the FDA for any of
its products (approval of which must be obtained prior to the commencement of
their commercial sale in the United States) until, at the earliest, the year
2001. The Company's long-term viability, profitability and growth will depend
upon successful commercialization of products resulting from its research and
development activities. To date, the Company has
 
                                       28
<PAGE>
recorded only limited product sales revenues, and these have been derived
primarily from sales in India of SA-12, a proprietary anti-bacterial surgical
scrub acquired by the Company from its inventor in 1995. The Company believes
that its ability to generate sufficient revenues to support its operations
primarily depends on the success of the Company in completing development, and
obtaining regulatory approvals for the commercial sale, of RA-11 and other
product candidates. There can be no assurance that any of such events will occur
or that the Company will ever achieve profitable operations.
 
INDUSTRY OVERVIEW
 
    According to an industry survey published in May 1997, the total worldwide
sales of prescription and over-the-counter pharmaceutical products in 1996 were
over $285 billion, of which the United States market represented over 33%.
Although growth in pharmaceutical sales has generally remained constant over the
past few years, future growth rates are expected to rise due to projected
population trends. Because a disproportionately large amount of pharmaceuticals
are prescribed for middle-aged and elderly people, expansion in these
demographic sectors bodes well for drug companies. Based on estimates by the
United States Department of Commerce, the over-65 segment and the 45- to
64-year-old segment of the population is expected to expand 16% and 46%,
respectively, from 1996 through 2010 as the baby boomers age. The influence of
these demographic trends should be especially pronounced for treatments
targeting chronic conditions that often afflict people as they age, such as
hypertension and arthritis.
 
    Currently, the incidence of rheumatoid arthritis is reported to be
approximately 2% of the world population and the incidence of clinically
symptomatic osteoarthritis is reported to be between 10-15% worldwide. Moreover,
in 1996, arthritis in general was reported by the American College of
Rheumatology ("ACR") to be the number one cause of disability in the United
States and the total market for prescription arthritis drug therapy was
estimated to be over $6 billion. For arthritis and other chronic,
difficult-to-treat conditions, such as viral hepatitis (of major medical
importance worldwide today and yet the only available treatments for which are
usually symptomatic and involve costly injectibles with numerous side effects),
plant-based pharmaceuticals with their natural attributes have potential to be
an efficient and cost-effective therapy.
 
    Plant-based pharmaceuticals have historically been a significant source of
therapy in Europe and other countries outside of the United States. In 1993, as
estimated by the Herbal Medical database, the phyto-pharmaceutical market was
approximately $12.4 billion worldwide of which $6.5 billion was attributed to
Europe. According to that publication, the industry had grown at an approximate
annual rate of 10-15% from 1985 through 1993, and it was estimated that such
growth rate would continue through at least 1998.
 
BUSINESS STRATEGY
 
    The Company's business strategy is to capitalize on what it perceives to be
an ever growing market for phyto-pharmaceutical therapies by developing (using
Ayurvedic principles as a means of potentially accelerating both the discovery
and the regulatory approval processes) and commercializing safe and effective
plant-based pharmaceuticals for the treatment of difficult-to-treat, chronic
diseases in humans. In furtherance of its strategy, the Company intends to:
 
    - OBTAIN FDA APPROVAL FOR RA-11 -- The Company intends to file an
investigational new drug ("IND") application with the FDA in the United States,
relating to the use of RA-11 for the treatment of rheumatoid arthritis,
osteoarthritis and other forms of non-infectious, inflammatory arthritis, during
the first quarter of 1998. The Company has already completed two large, double
blind, placebo controlled Phase II clinical trials in India relating to RA-11
and based upon the results of such trials, the Company believes that RA-11 may
prove to be an effective and safe drug for long-term treatment of osteoarthritis
and may be classified as a disease modifying anti-rheumatic in the long-term
treatment of rheumatoid arthritis. Subject to approval of its IND application,
of which there can be no assurance, the Company will
 
                                       29
<PAGE>
seek to by-pass Phase I clinical trials (preliminary trials which focus on
healthy human subjects) in the United States, proceeding directly to Phase II
clinical studies (intermediate level trials, focused on a limited target patient
population), since it has already conducted two large, well-documented efficacy
and safety Phase II level clinical trials in India using protocols consistent
with FDA guidelines, and to conduct a Phase III clinical trial concurrently in
India. Subject to successful results, the Company would then conduct a Phase III
clinical trial in the United States. The Company does not anticipate completing
clinical trials or filing an NDA until, at the earliest, the year 2001. See
"--The Regulatory Approval Process" and "-- Products and Product Candidates --
RA-11."
 
    - EXPAND INTERNATIONAL MARKETING EFFORTS FOR RA-11 AND SA-12 -- The Company
has begun to recognize early revenue from sales of SA-12 in India. In addition,
limited sales of RA-11 commenced in India in November 1997 under a
test-marketing program. The Company anticipates the commencement of marketing of
both RA-11 and SA-12 in certain countries in the Pacific Rim through a
pharmaceutical distributor in Singapore during the first half of 1998. The
Company is also in discussions with marketing companies for both products in
Indonesia and Korea. Pending regulatory approval of RA-11 by the FDA, the
Company will continue to target national pharmaceutical marketing companies in
markets outside Japan, Europe and the United States. See "--Marketing."
 
    - ESTABLISH CORPORATE PARTNERSHIPS WITH MULTI-NATIONAL PHARMACEUTICAL
COMPANIES -- To assist the Company in conducting clinical trials, the Company is
actively seeking collaborations or partnerships with major pharmaceutical
companies or research companies whereby such strategic partners would provide
the resources to continue clinical trials, obtain regulatory approvals and
provide marketing capabilities relating to a particular product candidate, in
exchange for the receipt of exclusive marketing rights to the product in
designated geographical areas or for designated therapeutic uses. The Company
would retain proprietary rights to the product and receive royalties based on
sales. As of the date hereof, however, the Company has not entered into any such
agreements or arrangements, and no assurance can be given that the Company will
be able to successfully negotiate collaborative agreements or that if concluded,
they will not eliminate or substantially reduce the Company's proprietary rights
in the applicable product. In addition to providing financing, the Company
believes such strategic partners could be instrumental in promoting product
penetration in key markets such as Europe, the United States and Japan, if and
when applicable regulatory approvals are received. See "--Marketing."
 
    - CONTROL MANUFACTURING -- For the foreseeable future, the Company intends
to have its products manufactured on a contract basis. All agreements will
contain provisions enabling the Company to maintain quality control over the
extraction, formulation and manufacturing processes (most of which are
proprietary to the Company). The Company's principal supplier of plant extracts
and raw material has achieved ISO-9000 certification (a worldwide industry
manufacturing standard), and the two formulation and finished product
manufacturers used by the Company in India have applied for GMP-certification
from the World Health Organization. The Company provides personnel to each of
the foregoing to support and supervise the extraction and manufacturing
processes. In connection with United States clinical trials, the Company intends
to import active plant ingredients in bulk and contract with third-party
manufacturers who have obtained GMP-certification from the FDA to produce the
finished and packaged product necessary for clinical trials. There are fewer
requirements applicable to the importation of bulk substances than to finished
pharmaceutical products. The Company's long-term goal is to operate its own FDA
GMP-certified manufacturing facilities in India. See "--Manufacturing and
Supply."
 
    - EXPAND PIPELINE OF PHYTO-PHARMACEUTICALS -- The Company has a number of
products in various stages of research and development. The Company will
continue to apply the principles of Ayurveda in an effort to discover and
develop new phyto-pharmaceuticals for the treatment of chronic,
difficult-to-treat diseases. The Company believes that the application of such
principles will enable it to rapidly identify new phyto-pharmaceuticals for
potential new applications. The Company's goal is to screen many sources through
an accelerated development process in a low-cost, high-quality location. See
"--The AyurCore Model of Drug Discovery and Development."

THE AYURCORE MODEL OF DRUG DISCOVERY AND DEVELOPMENT
 
    AYURVEDA
 
    Ayurveda is a medical science whose literature documents the study and use
of plants for medicinal purposes. Ayurveda comes from one of the most advanced
civilizations of the ancient world, India. In Sanskrit, the language in which
Ayurveda is documented, AYUR means life and VEDA means knowledge. Treatises,
written as early as 4,000 years ago, give essential information on the use,
safety and efficacy of certain medicinal plants for specific therapies. Safety
parameters were a primary goal in Ayurvedic medicine. Considerable work has been
done over the centuries in this science to define specific therapies for
specific symptoms and ailments. However, even with a documented history of
safety and efficacy, very little Ayurveda testing has been conducted in
accordance with United States standards in the past.
 
    The Company believes that by applying the knowledge gained from the study of
Ayurveda, it can rapidly identify the specific plant species to be utilized for
targeted indications. Because the safety and efficacy of the plants included in
Ayurveda have been documented, the Company believes it can make a significant
leap in the early drug discovery process, thereby accelerating the entire
development cycle and reducing pre-clinical costs.
 
    DRUG DISCOVERY & DEVELOPMENT PROCESS
 
    The Company has focused its efforts on several difficult-to-treat
disease/treatment areas. In India, the Company has assembled a multidisciplinary
team of scientists which plays an important role in the Company's drug discovery
and development process. These scientists include, but are not limited to,
biochemists, ethnobotanists, phytochemists, toxicologists, pharmacologists,
immunologists, and pharmaceutical chemists.
 
    This scientific team, along with Ayurveda specialists, search the Ayurvedic
literature to identify potential plant applications. The results of the search
are compared to modern medicine parameters, in terms of both diagnosis and
treatment. Once an Ayurveda/modern medicine interface is established, a plant
species is recommended for further evaluation in the treatment of a specific
disease condition. Identification of a plant lead is confirmed through the
testing of the plant's pharmacological activities, and subsequent investigation
of Ayurvedic and other scientific literature determines whether phytochemical
analysis of the plant has been undertaken by others previously. Based upon these
findings, purified extracts of the plant species are completed for
phyto-pharmaceutical applications. The resulting phyto-pharmaceutical candidate
must retain the desired characteristics of the original plant, yet be purified
and standardized to the level of pharmaceutical preparation quality. Once this
is accomplished, animal and human pharmacological screens are developed and
implemented using these standardized extracts or fractions thereof to establish
the efficacy of the drug for human therapeutic use.
 
    The Company's research and development team conducts activities consisting
of, but not limited to: (i) toxicology studies; (ii) further phytochemical
analysis/fractionation; (iii) any other applicable preclinical studies; (iv)
Phase I pharmacokinetic and pharmaco-dynamic studies in human volunteers; and
(v) Phase II-type dose ranging/efficacy studies. Given the history of use of
ayurvedic treatments in humans, these activities can, in some instances, be
conducted in parallel.
 
    Results of the above activities form the basis of the data required to file
an IND application with the FDA. With this approach, the Company believes it can
significantly reduce both the discovery and development time of
phyto-pharmaceuticals in the treatment of difficult-to-treat diseases.
 
                                       31

THE REGULATORY APPROVAL PROCESS
 
    GENERAL
 
    Pharmaceutical products, including phyto-pharmaceuticals, are significantly
regulated by a number of governmental entities, especially by the FDA in the
United States and by comparable authorities in other countries. These entities
regulate, among other things, research and development activities and the
testing, manufacture, safety, effectiveness, labeling, storage, record keeping,
approval, advertising, promotion, distribution and sale of such products.
Product development and approval within this regulatory framework takes a number
of years and involves the expenditure of substantial resources. Many products
that initially appear promising ultimately do not reach the market because they
are found to be unsafe or do not demonstrate efficacy during the testing
required by the regulatory process. In addition, there can be no assurance that
this regulatory framework will not change or that additional regulation will not
arise at any stage of a product's development that may affect approval, delay an
application or require additional expenditures. Moreover, even if approval is
obtained, failure to comply with present or future regulatory requirements, or
new information adversely reflecting on the safety or effectiveness of the
approved product, can lead to the FDA's withdrawal of approval to market the
product or other sanctions, including fines, recall or seizure of products,
injunctions and criminal prosecutions.
 
    UNITED STATES REGULATION
 
    In the United States, plant-derived pharmaceuticals are subject to FDA
review and approval as "drugs" under the Federal Food, Drug, and Cosmetic Act.
In most cases, the steps required before a new pharmaceutical can be
commercially distributed in the United States include: preclinical laboratory
and animal studies; the filing of an investigational new drug application, or
IND, with the FDA summarizing preclinical development work; controlled clinical
trials in humans to determine safety and efficacy; filing a new drug
application, or NDA, with the FDA; and FDA approval of the product for
commercial sale and of the product manufacturing facility for commercial
manufacturing.
 
    PRECLINICAL STUDIES AND GLP.  The initial testing of a pharmaceutical
product before it may be marketed in the United States is called preclinical
testing. Preclinical tests include formulation development, laboratory
evaluation of product chemistry and other end points and animal studies to
assess the potential safety and efficacy of the product as formulated. Many
preclinical studies are regulated by the FDA under a series of regulations
called the "Good Laboratory Practice" regulations. Violations of GLP regulations
can, in some cases, lead to invalidation of the studies, requiring them to be
replicated. The results of preclinical trials are submitted to the FDA as part
of the IND and are reviewed by the FDA prior to authorizing the sponsor to
conduct clinical trials in human subjects.
 
    THE IND.  FDA regulations provide that human clinical trials may begin 30
days following the submission and receipt of an IND, unless the FDA advises
otherwise or requests additional information, clarification or additional time
to review the IND submission. There is no assurance that the submission of an
IND will eventually allow a company to commence clinical trials. Once trials
have commenced, the FDA may stop the trials, or particular types of trials, by
placing a "clinical hold" on such trials because of concerns about, for example,
the safety of the product being tested or the adequacy of the trial design. Such
holds can cause substantial delay and in some cases may require abandonment of a
product. There can be no assurance that the FDA's acquiescence in an IND
constitutes any indication that the FDA will find the protocol satisfactory for
a clinical trial or that authorization of one phase of clinical trials will
result in authorization of other phases or that the FDA will accept any data
generated from a clinical trial.
 
    CLINICAL TRIALS.  Clinical trials involve the administration of the
investigational drug product to human subjects. Each protocol indicating how the
clinical trial will be conducted must be submitted for review to the FDA. The
FDA's review of a study protocol does not necessarily mean that, if the study is
successful, it will constitute proof of efficacy or safety. Further, each
clinical trial must be conducted under the auspices of an institutional review
board ("IRB"), which must be constituted and operated in conformance with FDA
regulations. The IRB considers, among other factors, ethical concerns and
informed consent
 
                                       32
<PAGE>
requirements. The FDA or the IRB may require changes in a protocol both prior to
and after the commencement of a trial.
 
    Clinical trials are typically conducted in three sequential phases, although
in certain cases, the phases may overlap. In Phase I trials (which constitute
the initial introduction of the pharmaceutical into human subjects) the
pharmaceutical is tested in healthy subjects, as opposed to patients, primarily
for safety (adverse effects), side effects, metabolism, clinical pharmacology
and optimal dosage. Phase II trials involve studies in a limited target patient
population to (i) further evaluate optimal dosage, (ii) identify possible
adverse effects and safety risks and (iii) determine the efficacy of a drug for
a specific indication. These can be further classified into Phase IIa trials,
which study dose ranging and schedule optimization from the perspective of
efficacy, and Phase IIb trials, which study (in parallel or individually) one
dose and one schedule (the frequency of dose administration) to determine length
of therapy and safety versus efficacy. When a product is found to have an
acceptable safety profile in Phase II evaluation, Phase III clinical trials are
undertaken to evaluate clinical efficacy and to further test for safety within
an expanded target patient population at geographically dispersed multiple
clinical study sites. The FDA may order the temporary or permanent
discontinuation of a clinical trial at any time for any reason. There can be no
assurance that Phase I, Phase II or Phase III testing will be completed
successfully within any specified time period, if at all, with respect to any of
the Company's products.
 
    THE NDA.  Upon completion of clinical trials, the results of the preclinical
studies and the human clinical trials are submitted to the FDA in an NDA,
approval of which must be obtained prior to commencement of commercial sales.
The NDA also includes information pertaining to the preparation of drug
substances, analytical methods, drug product formulation, details on the
manufacture of finished product and proposed product packaging and labeling. The
interval between the filing of the IND and the filing of an NDA application can
be lengthy. In general, the FDA requires at least two properly conducted and
well-controlled Phase III clinical trials demonstrating efficacy. The FDA may
deny an NDA if, among others reasons, clinical trial protocols are not adequate
or appropriate. The FDA also may deny an NDA or require additional testing or
information to assess the safety of the product if the FDA does not view the NDA
as containing adequate evidence of the product's safety and efficacy.
Notwithstanding the submission of such data, the FDA may ultimately decide that
the application does not satisfy its regulatory criteria for approval and, even
if the NDA is approved, the product may be required to undergo post-licensure
testing and surveillance to continue to monitor its safety and effectiveness
(Phase IV studies).
 
    POST-MARKETING APPROVAL REQUIREMENTS.  Once an NDA has been approved, the
NDA applicant remains subject to post-marketing requirements. These include
manufacturing, record keeping, and reporting obligations. For instance, any
adverse experiences relating to the use of the product must be reported to the
FDA. Failure to comply with the FDA's post-marketing obligations can result in
the FDA's withdrawal of approval, seizures, injunctions, and/or civil or
criminal penalties.
 
    In the United States, in addition to patent protection, drug products
containing new chemical entities ("pioneer drugs") approved through the NDA
process may be subject to periods of marketing exclusivity. After the applicable
patents and periods of exclusivity expire, however, those pioneer drugs are
subject to competition from generic versions (duplicate or related versions) of
themselves. The FDA may approve an abbreviated NDA for the marketing of a
generic drug (I.E., a duplicated or related version of an approved pioneer drug)
that has been shown to be as safe and effective as a pioneer drug whose patents
have expired, without requiring the submission of "full reports" of safety and
effectiveness.
 
    MANUFACTURING REGULATIONS.  The FDA mandates that drugs be manufactured in
conformity with current Good Manufacturing Practice ("cGMP") regulations. In
complying with the cGMP regulations, manufacturers must continue to expend time,
money and effort in production, record keeping and quality control to ensure
that the product meets applicable specifications and other requirements. The FDA
periodically inspects drug manufacturing facilities to ensure compliance with
applicable cGMP requirements. Failure to comply subjects the manufacturer to
possible FDA action, such as suspension of
 
                                       33
<PAGE>
manufacturing, seizure of the product, voluntary recall of a product, fines,
injunctions, failure to approve a product, or withdrawal of approval of a
product.
 
    FOREIGN REGULATIONS
 
    To market its products abroad, the Company is also subject to numerous and
varying foreign regulatory requirements, implemented by foreign health
authorities, governing, among other things, the design and conduct of human
clinical trials, product pricing and reimbursement, and marketing approval
criteria. The approval procedure currently varies among countries and can
involve additional testing. As a result the time required to obtain foreign
approvals may differ from that required to obtain FDA approval. At present,
foreign marketing authorizations are applied for at a national level, although
within the European Union certain uniform registration procedures are available
to companies wishing to market a product in more than one member country. The
foreign regulatory approval process includes all of the risks associated with
obtaining FDA approval set forth above. However, approval by the FDA does not
ensure approval by other countries. RA-11 has been approved for commercial sale
in India by the Indian FDA-equivalent.
 
PRODUCTS AND PRODUCT CANDIDATES
 
    RA-11
 
    GENERAL.  RA-11, the Company's lead phyto-pharmaceutical, is derived from a
combination of four different plant species. The Company holds an exclusive
license on two Indian patents relating to its proprietary plant extraction and
RA-11 formulation processes, as well as a United States patent relating to RA-11
and its use in treating degenerative musculoskeletal diseases, such as
rheumatoid arthritis and osteoarthritis. Incidence of rheumatoid arthritis is
reported to be approximately 2% of the world population and the incidence of
clinically symptomatic osteoarthritis is reported to be between 10-15%
worldwide. Based on clinical trials conducted in India under protocols
consistent with FDA guidelines and ACR criteria, the Company believes that RA-11
may prove to be an effective and safe drug for long-term treatment of
osteoarthritis and may be classified as a disease modifying, anti-rheumatic drug
for the long-term treatment of rheumatoid arthritis. The Company plans to file
an IND application with the FDA during the first quarter of 1998. See "--The
Regulatory Approval Process" and "--Patents, Licenses and Proprietary Rights."
 
    RHEUMATOID ARTHRITIS.  Rheumatoid arthritis is an immunological disease
characterized by inflammatory arthritis of peripheral joints and associated with
a number of other manifestations. Treatments available today include steroids,
non-steroidal anti-inflammatory drugs ("NSAIDs")(eg. Diclofenac and Naproxen),
and disease modifying anti-rheumatic drugs (E.G. Methotrexate and gold salts).
All of these treatments can be accompanied by serious side effects, and the
duration of the therapeutic effects associated with steroid and NSAID treatment
is relatively brief. Newer agents under development include specific
target-oriented monoclonal antibodies and the cyclo-oxygenase-2 inhibitors.
 
    RA-11 was initially evaluated for use in treating rheumatoid arthritis in a
small clinical trial in India. During 1994 and 1995, the Company conducted a
large Phase IIb trial in India of RA-11's efficacy and safety using ACR criteria
and FDA guidelines. This study was comprised of two parts: a 16 week, double-
blind, placebo-controlled, parallel trial, followed by a crossover study in
these patients. Out of a total of 1,445 arthritis patients screened, 182
patients participated in the study. Of these 182 patients, 165 patients
completed the full 16 weeks of the study. The treatment groups were matched with
respect to demographics at study entry. The protocol for both the double-blind
phase and the 16-week open label phase of the trial were prepared for the study
by Dr. Richard Polisson, the Clinical Director of Massachusetts General
Hospital's arthritis unit; statistics were performed by Boston Biostatistics,
Inc.; and Dr. Arvind Chopra, a rheumatologist associated with the
Interdisciplinary School of Health Sciences at the University of Pune, served as
the Chief Investigator for the trial. See "--Consultants."
 
                                       34
<PAGE>
    Results obtained at the conclusion of the 16-week study, indicated that
patients on the drug did better than the placebo group in several clinical and
lab parameters. Statistical significance, however, as defined by the ACR and
FDA, was obtained in only two important clinical parameters--joint count and
score for swelling--and two lab indicators--rheumatoid factor and hemoglobin
count.
 
    After 32 weeks of participation in the study, however, patients showed
statistically significant improvements from baseline, as defined by the ACR and
FDA, in all clinical criteria and, most importantly, in the latest laboratory
blood testing criteria: Interleukin-6, C-Reactive protein and Erythrocyte
sedimentation rate. These patients were further followed for 54 weeks in an open
label phase and RA-11 continued to have persistent efficacy results in both
clinical and lab criteria. The Company believes that the safety of RA-11 is
demonstrated by the fact that the incidence of minor side effects was similar in
placebo and active groups through the course of the study. Based on the data
obtained from the study, the Company believes that RA-11 has shown promising
results as a safe disease-modifying anti-rheumatic drug which can be indicated
in the long-term therapy of rheumatoid arthritis. A total of 111 patients from
the original study have now been followed for more than 3 1/2 years, and all
have remained in clinical remission (free from clinical signs and symptoms of
arthritis), free of significant side effects and with stable, normal blood
counts, serum electrolytes, and renal and liver function tests.
 
    Concurrent with the clinical trials, the Company completed acute, subacute
and chronic toxicity studies in albino rats. These studies were not performed in
a United States GLP-certified laboratory. The animals were tested for all
typical potential toxic effects such as gastrointestinal, central nervous
system, respiratory, food consumption, abnormal secretions and alteration of
fur. The drug was administered in several multiples of therapeutic doses. In the
chronic model (6 months) there was mild incidence of bronchopneumonia (which the
Company believes can be explained by force feeding of drug/placebo and hence
aspiration) equal in both active and placebo groups. Also noted were mild,
cloudy changes in the kidneys of certain of the animals, in both placebo and
active groups, and which the Company does not believe is significant. Part of
the proceeds of the Offering will be used to repeat these studies as well as
carcinogenicity and mutagenicity studies at a United States GLP-certified and
AALAC (American Association for Laboratory Animal Certification) accredited
laboratory.
 
    OSTEOARTHRITIS.  Osteoarthritis, also known as degenerative joint disease,
is believed to be the most common human joint disease. With the significant
increase in age expectancy in both developed and developing countries, it is
anticipated that the incidence of osteoarthritis will increase significantly
over the next decade.
 
    Therapy in osteoarthritis is primarily with NSAIDs, but limited due to lack
of efficacy over long periods of time and/or side effects and toxicity. Steroid
injections provide temporary relief, and may be used in conjunction with
physical therapy. The patient may require surgical replacement of the affected
joints as a last resort.
 
    During 1995 and 1996, the Company conducted a large 32-week Phase IIb
double-blind, placebo-controlled clinical trial using patients with established
osteoarthritis of the knee. As in the rheumatoid arthritis trial, the protocol
and study design were prepared by Dr. Polisson, statistics were performed at
Boston Biostatistics, Inc., and Dr. Chopra served as the Chief Investigator. The
drug dosing was twice that of the rheumatoid arthritis trial. Patients in this
trial were also matched with respect to demographic characteristics at study
entry. At the end of the study, patients receiving RA-11 performed better with
respect to almost all of the parameters used in this trial. Statistical
significance, as determined by the ACR and FDA, was achieved in several
important efficacy variables including scientific standards or criteria for
stiffness, pain and difficulty and scores for pain. Low incidence of minor side
effects was equal in the treatment and placebo groups.
 
                                       35
<PAGE>
    IM-10
 
    IM-10 is an oral phyto-pharmaceutical candidate derived from a single plant.
Extracts of this plant have demonstrated both immunosuppressive and
immunostimulatory properties. IM-10 is comprised of the immunostimulatory
compounds found in the plant extract and is currently undergoing preclinical
animal pharmacology testing for the stimulation and restoration of bone marrow
and the immune system in cancer patients being treated with chemotherapy. Due to
the high toxicity of chemotherapeutic agents, patients undergoing chemotherapy
often suffer compromised immune systems and significant drops in blood cell
counts. The Company has an exclusive worldwide license to IM-10. See "--Patents,

    In preliminary animal studies conducted by the Company in India, IM-10
showed an ability to restore to normal levels the immune system of animals
exposed to anti-cancer agents. Animals were given known anti-cancer agents which
severely depress the immune system and cause a significant drop in blood cell
counts (red blood cells, white blood cells and platelets). When IM-10 was
administered in the presence of the known anti-cancer agents, it restored the
immune system back to normal or baseline levels and increased blood cell counts.
The Company is currently conducting a much larger animal study with IM-10 in
India and similar pharmacological studies for efficacy are scheduled to start in
the first quarter of 1998, at the Veteran's Administration Hospital in Palo
Alto, California. Subject to satisfactory animal pharmacology testing, the
Company plans to determine human dosing and develop a large-scale, dose-ranging,
tolerance and efficacy trial for IM-10 in human patients undergoing cancer
chemotherapy. This study would be a placebo controlled, double-blind clinical
trial at Tata Memorial Cancer Research Center and Hospital, a cancer treatment
and research facility in Mumbai (previously known as Bombay), India. Using
protocols consistent with FDA guidelines, the Company anticipates beginning this
trial during the first quarter of 1998.
 
    The competition in this area consists of cell stimulating drugs such as
Leukine, Neupogen and Alpha Interferon. Besides being very expensive, all of
these are currently available only in injectable forms and can potentially have
serious side effects. IM-10 is formulated in an oral capsule form, and in prior
testing by other investigators, the plant extract from which IM-10 is derived
has been shown to be safe in multiples of IM-10's intended therapeutic range.
 
    HP-11
 
    HP-11, an oral phyto-pharmaceutical candidate derived from a single plant
species, has demonstrated an ability to protect and regenerate destroyed liver
cells in preliminary testing. Other species of the same plant have been
evaluated and found to have hepato-protective (protection of liver tissue) and
hepato-regenerative (regeneration and repair of liver tissue) properties.
However, the Company believes that these other species have significant toxic
effects at relatively low therapeutic doses. The Company believes that the plant
species used in HP-11 has a much broader therapeutic index, with very high
safety margins. HP-11 was identified through the research efforts of the
Company's scientific team in India.
 
    The goal of the Company's research and development activities with respect
to HP-11 is to demonstrate hepato-protective as well as hepato-regenerative
activity in the prevention and treatment of all forms of hepatitis, especially
hepatitis A, hepatitis B, hepatitis C and chemically induced (such as with
toxins, alcohol or drugs) hepatitis. Hepatitis is a disease of the liver
characterized by inflammation and damage of liver cells and loss of all
important liver functions. Viral hepatitis is of major medical importance
worldwide today. Very little treatment exists today for hepatitis. The only
treatment is usually symptomatic, for general management of the patient's
clinical condition and improving general nutrition. In very advanced cases,
interferon offers a general palliative therapy. Recently, the FDA approved a new
bioengineered interferon, Infergen, in the treatment of hepatitis C. Both forms
of therapy are injectables with side effects and are costly. The Company's
immediate plans for HP-11 include fractionation to isolate the most active
compounds and in-vitro activity evaluation on human liver cells. Fractionation
would be
 
                                       36
<PAGE>
followed by trials to determine bioavailability (the rate and extent to which
the active compounds enter the general circulation).
 
    BV-6
 
    BV-6 is a naturally-occurring, biological, single molecule. BV-6, which is
derived from an animal cell component, is undergoing testing for the treatment
of degenerative diseases of the central nervous system, including seizure
disorders, strokes, multiple sclerosis and Alzheimer's disease. BV-6 has been
tested in cultured central nervous system neurons and in animals. BV-6 appears
to act by bypassing certain receptors in the brain that cause degeneration of
the brain tissue and, to date, has exhibited no toxicity over the entire
physiologically effective concentration range.
 
    The National Institutes of Health awarded an SBIR grant in the amount of
$100,000 to the Company in September 1996. Those studies have been successfully
completed, confirming the previous findings and a report has been submitted. An
additional SBIR grant application for $750,000 was submitted in April 1997 for
further animal studies. In 1995, the Company was assigned a pending United
States patent application related to BV-6. See "Patents, Licenses and
Proprietary Rights."
 
    SA-12
 
    SA-12, a non-plant based, proprietary antibacterial surgical scrub and
general disinfectant (not a pharmaceutical) for use on the hands or other skin
surfaces, was acquired by the Company from the product's inventor in 1995.
 
    SA-12 is a scented, fast drying liquid, requiring no wipe-off, and it leaves
no oily feel after evaporation. SA-12 does not appear to irritate the skin. The
Company has tested the skin of SA-12 treated subjects for the presence of common
pathogens (streptococcus, staphylococcus, etc.) and has found no measurable
concentrations of microbial content for over two hours on the treated skin
(hands). Similar results were also obtained for highly virulent but less common
organisms such as Pseudomonas, E. coli and Candida Albicans. In a comparative
study, SA-12 was superior in terms of spectrum, speed and duration of activity
to the most widely used and known antibacterial agents currently available such
as Betadine, PhisoHex, Hibiclens and Sterillium.
 
    SA-12 is comprised of ingredients listed in the United States Pharmacopeia
and can be produced at a cost which the Company believes will enable it to
compete effectively in developing countries, in very price sensitive healthcare
sectors, such as hospitals, and the food industry.
 
    The product was launched in India in the second quarter of 1997 under the
brand name Multicidal-Registered Trademark- and is in the process of being
introduced in Pacific Rim countries and elsewhere under the brand name
Periban-TM-. The initial introduction has been targeted at hospitals, clinics
and physician offices. After an initial period, the Company may consider
promoting the product directly to consumers in the over-the-counter market. The
Company has no present intention of marketing SA-12 in the United States. See
"--Marketing" and "--Patents, Licenses and Proprietary Rights."
 
    Currently, the Company is marketing 500 ml and 200 ml plastic dispenser
bottles, as well as pump dispensers. Additional consumer line extensions which
the Company may explore include small towel wipes in unit packages, soaps, body
lotions and other convenient applications.
 
MANUFACTURING AND SUPPLY
 
    The Company currently relies on Kancor Flavours & Extracts Pvt. Ltd.
("Kancor") located in Southern India to provide all of the plant extracts used
in the production of RA-11. Kancor's production facility is ISO-9000 certified.
Kancor and the Company have entered into a five-year renewable agreement
covering the supply of these plant extracts. Plant extracts used in the
production of IM-10 and HP-11 for testing purposes are purchased on an
order-by-order basis. The Company has been and expects to continue
 
                                       37
<PAGE>
to be able to obtain plant extracts in quantities sufficient for its testing and
commercial production purposes for at least the next 12 months without any
significant interruption or sudden price increase, although there can be no
assurance thereof. Even though all plants used in the production of the
Company's phyto-pharmaceuticals are commercially cultivated, no assurance can be
given of continual sources of supply of required materials or that reasonable
arrangements can be made for their supply. Supply risks include unexpected
changes in regulatory requirements, exchange rates, tariffs and barriers,
difficulties in coordinating and managing foreign operations, potentially
adverse tax consequences and disruptions in the political and economic stability
of India and the other regions in which the Company's source plants are grown as
well as seasonality and weather factors. Interruptions in supply or material
increases in the cost of the supply could have a material adverse effect on the
Company's financial condition and results of operations. Kancor has indicated
that it intends to build a stand alone facility which would be designed to meet
the FDA's GMP requirements for bulk active pharmaceutical ingredients. The
Company is in preliminary discussions with Kancor regarding utilization of such
facility to produce bulk ingredients for the Company's phyto-pharmaceuticals.
 
    In October 1997, the Company entered into an agreement with Eisen
Pharmaceutical Co. (Pvt.) Ltd. of Pune, India ("Eisen"), for the manufacture of
RA-11. The agreement has a five-year term and is terminable by either party upon
three months' notice. Pursuant to the terms of the agreement, the Company
supplies the manufacturer with the raw materials used in, and retains a
supervisory role over, the manufacturing process. The Company operates under a
similar arrangement with S.P.B. (Inc.) of Pune, India for the manufacture of
SA-12, although no formal agreement has yet been entered into. Each of S.P.B.
(Inc.) and Eisen has applied for a GMP approval rating for finished formulations
from the World Health Organization. The loss of the manufacturing capacitates of
either S.P.B. (Inc.) or Eisen would cause an interruption in the supply of
products produced by the respective manufacturer. This could, in turn, have a
material adverse effect on the Company's financial condition and results of
operations.
 
    To provide the Company's requirements of RA-11 for United States clinical
trials, the Company intends to import active ingredients in bulk into the United
States. The United States has fewer requirements for import of active
ingredients and formulations than for finished formulations. The Company would
seek to enter into arrangements with third-party manufacturers which are United
States GMP-certified to supply finished product. The Company's long-term goal is
to build or acquire a United States GMP-certified manufacturing base in India to
produce the products sold by the Company in India and other countries.
 
MARKETING
 
    The Company has no marketing or sales staff and currently intends to rely on
third-party distributors for the sale and marketing of all products it may
develop.
 
    In April 1996, the Company entered into a memorandum of understanding with
Blue Cross Laboratories Ltd, of Mumbai (previously known as Bombay), India
("Blue Cross"), in connection with the distribution in India of SA-12 (the "BCL
Agreement"). Pursuant to the BCL Agreement, the Company is obligated to cause
S.P.B. (Inc.) to manufacture and deliver SA-12 to Blue Cross for distribution.
In addition to a negotiated sales price, Blue Cross will pay the Company a
percentage of all sales of SA-12 made by Blue Cross through March 31, 2001, the
expiration date of the BCL Agreement.
 
    Effective September 1997, the Company entered into a distribution agreement
(the "MD Agreement") with MD Pharmaceuticals Laboratories Ltd. for the marketing
of RA-11 and SA-12 in Singapore, Thailand and other Pacific Rim countries. The
MD Agreement is a three-year renewable direct marketing supply and distribution
agreement pursuant to which the Company sells finished product at an agreed upon
price.
 
    In September 1997, the Company entered into a memorandum of understanding
with Alembic Chemical Works Co. Limited ("Alembic") of Baroda, India for the
distribution in India of RA-11 (the
 
                                       38
<PAGE>
"Alembic Agreement"). Pursuant to the Alembic Agreement, the Company's
subsidiary will manufacture and package RA-11 and sell it to Alembic at an
agreed upon price. Initially, Alembic is only required to test market RA-11 in
the State of Maharashtra, during which time an assessment regarding the
acceptance and effectiveness of RA-11 will be made. Alembic will be required to
implement a national launch of RA-11 by April 1, 1998, subject to satisfactory
results obtained during test marketing. If no definitive agreement is entered
into between the parties before March 31, 1998, neither party will have any
continuing obligation to the other. RA-11 will be marketed under the trade name
ARTREX-TM-.
 
    The Company will continue to seek distribution arrangements with national
pharmaceutical distributors in countries other than the United States, Europe
and Japan. For products that may be sold in the United States and other large
markets, the Company will seek alliances or collaborative arrangements with
pharmaceutical companies that have established sales forces as well as the
ability and expertise to conduct clinical trials and finished product
manufacturing. The Company may license the products to such an entity or
entities in exchange for licensing and/or royalty payments. In any such
relationship, the Company's goal would be to supply the active raw material in
bulk to such entities who would then be responsible for finished product
manufacture and marketing. The Company cannot assure that it will be able to
enter into any such arrangements on terms acceptable to the Company, or at all.
 
COMPETITION
 
    Competition in the pharmaceutical industry is extremely intense. The
principal factors upon which such competition is based include the following:
marketing, distribution, price, therapeutic efficacy, side effect profile, ease
of use, safety, physician acceptance and patient compliance. Many pharmaceutical
companies have significantly greater research and development capabilities, as
well as substantially greater marketing, financial and human resources than the
Company. In addition, many of these competitors have significantly greater
experience than the Company in undertaking preclinical testing and human
clinical trials of new pharmaceutical products and obtaining regulatory
approvals of such products. These companies may represent significant long-term
competition for the Company.
 
    There can be no assurance that developments by other pharmaceutical
companies will not render the Company's products or technologies obsolete or
noncompetitive or that the Company will be able to keep pace with technological
developments of its competitors. Many of the Company's competitors have
developed or are in the process of developing technologies that are, or in the
future may be, the basis for competitive products. Some of these products may
have an entirely different approach or means of accomplishing the desired
therapeutic effect than products being developed by the Company. These competing
products may be more effective and less costly than the products developed by
the Company.
 
PATENTS, LICENSES AND PROPRIETARY RIGHTS
 
    TECHNOLOGY AGREEMENTS
 
    The Company has entered into license agreements with Dr. Bhushan Patwardhan
pursuant to which the Company acquired exclusive worldwide rights to RA-11. One
agreement relates to the rights to commercialize RA-11 in India and the other
agreement relates to similar rights throughout the rest of the world. To
maintain its rights under the RA-11 agreements, in addition to paying royalties
on sales, the Company must commence marketing in India by January 1998 and
commence marketing outside India by 2003. The Company is currently in compliance
with its obligations under the agreements. The Company has also entered into a
license agreement with Dr. Patwardhan pursuant to which the Company acquired
exclusive worldwide rights to IM-10. To maintain its rights under the agreement,
in addition to paying royalties on sales, the Company must commence marketing in
India within one year of clinical confirmation and approval by the Drug
Controller of India (India's FDA equivalent) and commence marketing in at least
one country outside India within seven years of its initial marketing in India.
See "--Consultants."
 
                                       39
<PAGE>
    In December 1995, the Company entered into an agreement with Dr. Abraham
Rosenberg pursuant to which the Company was assigned a United States patent
application related to BV-6, in exchange for royalties. See "--Consultants."
 
    In June 1995, the Company entered into an agreement with S.V. Karnataki
pursuant to which the Company purchased SA-12 and related technology for an
initial signing fee and limited manufacturing and marketing milestone payments.
 
    PATENTS AND PROPRIETARY RIGHTS
 
    The Company's policy is to protect its technology by filing patent
applications. In addition to intending to file patent applications in the United
States, the Company has filed, and intends to file, patent applications in
foreign countries on a selective basis. The Company also relies on trade
secrets, unpatented know-how and technological innovation to develop and
maintain its competitive position.
 
    The Company is the exclusive licensee under an issued United States patent,
which expires in 2014, relating to RA-11 and its use in treating degenerative
musculoskeletal disorders, including rheumatoid arthritis and osteoarthritis.
The Company also holds an exclusive license on two Indian patents, one of which
relates to the Company's proprietary plant extraction process and the other to
the Company's proprietary process for formulating RA-11, which expire in 2001.
However, the Company's licensor does not have any patent rights relating to
RA-11 outside of the United States and India. In addition, the Company has a
United States patent application pending for the use of BV-6 in the treatment of
degenerative diseases of the central nervous system.
 
    Although a patent has a statutory presumption of validity in the United
States, the issuance of a patent is not conclusive as to such validity or as to
the enforceable scope of the claims of the patent. There can be no assurance
that the Company's issued patent or any patents subsequently issued to or
licensed by the Company will not be successfully challenged in the future. The
validity or enforceability of a patent after its issuance by the patent office
can be challenged in litigation. If the outcome of the litigation is adverse to
the owner of the patent, third parties may then be able to use the invention
covered by the patent without payment. There can be no assurance that the
Company's patents will not be infringed or successfully avoided through design
innovation.
 
    There can be no assurance that patent applications owned by or licensed to
the Company will result in patents being issued or that, if issued, the patents
will afford protection against competitors with similar technology. It is also
possible that third parties may obtain patent or other proprietary rights that
may be necessary or useful to the Company. In cases where third parties are
first to invent a particular product or technology, it is possible that those
parties will obtain patents that will be sufficiently broad so as to prevent the
Company from using certain technology or from further developing or
commercializing certain product candidates. If licenses from third parties are
necessary but cannot be obtained, commercialization of the product candidates
would be delayed or prevented.
 
    There may be patent applications and issued patents belonging to competitors
that may require the Company to alter its product candidates, pay licensing fees
or cease certain activities. If the Company's products or product candidates
conflict with patents that have been or may be granted to competitors,
universities or others, such other persons could bring legal actions against the
Company claiming damages and seeking to enjoin manufacturing and marketing of
the affected products. If any such actions are successful, in addition to any
potential liability for damages, the Company could be required to obtain a
license in order to continue to manufacture or market the affected products.
There can be no assurance that the Company would prevail in any such action or
that any license required under any such patent would be made available on
acceptable terms or at all. The Company believes that there may be significant
litigation in the industry regarding patent and other intellectual property
rights. If the Company becomes involved in such litigation, it could consume
substantial resources.
 
                                       40
<PAGE>
    The enactment of the legislation implementing the General Agreement on Trade
and Tariffs has resulted in certain changes to United States patent laws that
became effective on June 8, 1995. Most notably, the term of patent protection
for patent applications filed on or after June 8, 1995 is no longer a period of
seventeen years from the date of grant. The new term of United States patents
will commence on the date of issuance and terminate twenty years from the
earliest effective filing date of the application. Because the time from filing
to issuance of patent applications is often more than three years, a twenty-year
term from the effective date of filing may result in a substantially shortened
term of patent protection, which may adversely impact the Company's patent
position. If this change results in a shorter period of patent coverage, the
Company's business could be adversely affected in the future, to the extent that
the duration and level of the royalties it is entitled to receive from its
potential collaborators is based on the existence of a valid patent. None of the
issued patents currently owned or licensed by the Company are adversely affected
by these changes in the term of patent protection.
 
    At present, India only grants process patents for pharmaceutical products.
Although India is not a signatory of the Paris Convention, it is a member of the
World Trade Organization ("WTO"). As a signatory of WTO, India is required to
comply with its obligations under Trade-Related Aspects of Intellectual Property
Rights ("TRIPS"). TRIPS requires India to grant product patents for
pharmaceutical products after a certain transition period. During the transition
period, participating countries must establish a means for filing patent
applications relating to pharmaceutical products and agricultural chemicals and
also grant exclusive marketing rights for certain periods. In response to claims
raised by other countries, WTO ruled that India has not been abiding by its
transition period commitments under TRIPS. As of the date of this Prospectus, it
is expected that India will appeal the WTO decision. In addition, as an
aftermath of the Convention on Biological Diversity, India is planning to enact
a law on national bio-diversity. This law may place restrictions and/or
conditions for obtaining patents or other intellectual property relating to
biological material or products derived therefrom.
 
    The Company also relies on unpatented technology, trade secrets and
information and no assurance can be given that others will not independently
develop substantially equivalent information and techniques or otherwise gain
access to the Company's technology or disclose such technology, or that the
Company can meaningfully protect its rights in such unpatented technology, trade
secrets and information. The Company requires each of its employees, consultants
and advisors to execute a confidentiality agreement at the commencement of an
employment or consulting relationship with the Company. The agreements generally
provide that all inventions conceived by the individual in the course of
employment or in providing services to the Company and all confidential
information developed by, or made known to, the individual during the term of
the relationship shall be the exclusive property of the Company and shall be
kept confidential and not disclosed to third parties except in limited specified
circumstances. There can be no assurance, however, that these agreements will
provide meaningful protection for the Company's information in the event of
unauthorized use or disclosure of such confidential information.
 
    TRADEMARKS
 
    The Company seeks to file trademark applications on major products before
the products are publicly available. The following table reviews the Company's
current trademark filings:

OTHER GOVERNMENT REGULATION
 
    COVERAGE AND REIMBURSEMENT BY THIRD PARTY PAYERS
 
    The ability of the Company to successfully commercialize any products that
receive FDA approval will depend, in part, on coverage and reimbursement of such
products by third-party payers, such as government health care programs,
indemnity insurers, and managed care organizations. Significant uncertainty
exists as to the coverage and reimbursement status of pharmaceuticals and other
products following approval by the FDA. Government and other third-party payers
are increasingly attempting to contain costs by limiting both coverage and
reimbursement for pharmaceuticals and products approved for marketing by the FDA
and by refusing, in some cases, to provide coverage of approved pharmaceuticals
and products for disease indications for which the FDA has not granted marketing
approval. Payers are also increasingly applying cost effectiveness criteria to
new therapies for which alternatives exist. There can be no assurance that the
Company's products will be deemed cost effective compared to other alternative
therapies, or that adequate third-party coverage and reimbursement will be
available for the Company to realize an appropriate return on its investment. If
adequate coverage and reimbursement is not provided by government and other
third-party payers for uses of the Company's products, the market acceptance of
these products could be adversely affected.
 
    HEALTH CARE "FRAUD AND ABUSE"
 
    Once the Company's products are marketed in the United States, the Company
(and other entities marketing, purchasing, or seeking reimbursement for the
Company's products), will be subject to various federal and state laws
pertaining to health care "fraud and abuse," including anti-kickback laws and
false claims laws. Anti-kickback laws make it illegal to solicit, offer,
receive, or pay any remuneration in exchange for, or to induce, the referral of
business, including the purchase or prescription of a particular drug. False
claims laws prohibit anyone from knowingly and willfully presenting, or causing
to be presented, claims for payment to third party payers (including Medicare
and Medicaid) that are false or fraudulent, for items or services not provided
as claimed, or for medically unnecessary items or services. Thus, the Company's
activities relating to sale and marketing of its products, including any advice
that might be given concerning billing or reimbursement, would be subject to
scrutiny under these laws. Violations of fraud and abuse laws are punishable by
criminal and/or civil sanctions, including in some instances imprisonment and
exclusion from participation in federal health care programs, such as Medicare
and Medicaid. The Company intends to structure its sales, marketing and other
activities to comply with these and other laws. However, given the broad reach
of these laws, there can be no assurance that the Company's future activities
would not be subject to scrutiny and/or challenge at some time in the future.
 
    ENVIRONMENTAL REGULATION
 
    In connection with its research and development activities and its
manufacturing of clinical trial materials, the Company is subject to laws and
standards prescribed by the Indian government, and will be subject to United
States federal, state and local laws, rules, regulations and policies governing
the use, generation, manufacture, storage, air emission, effluent discharge,
handling and disposal of certain materials and wastes. There can be no assurance
that the Company will not be required to incur significant costs to comply with
environmental and health and safety regulations in the future. The Company's
research and development involves the controlled use of hazardous materials,
chemicals, viruses and animal tissues. Although the Company believes that its
safety procedures for handling and disposing of such materials comply with the
standards prescribed by state and federal regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. In
the event of such an accident, the Company could be held liable for any damages
that result and any such liability could exceed the resources of the Company.
 
                                       42
<PAGE>
    OTHER REGULATION
 
    The Company is also subject to laws of more general applicability dealing
with issues such as occupational safety, employment, medical leave, and civil
rights and discrimination. In the United States, federal, state and local
governments in many instances are expanding the regulatory requirements on
businesses, and the imposition of these regulatory requirements may have the
effect of increasing operating costs and reducing the profitability of the
Company's operations.
 
    HEALTH CARE REFORM
 
    In the past several years there have been numerous initiatives in the United
States on the federal and state government levels for comprehensive or
incremental reforms affecting the payment for health care services and products,
including a number of proposals that would significantly limit reimbursement
under the Medicare and Medicaid programs. The Company anticipates that federal
and state governments will continue to review and assess alternative health care
delivery systems and payment methodologies. It is not clear at this time what
existing or future proposals, if any, will be adopted or, if adopted, what
effect such proposals would have on the Company's business. Aspects of certain
of these health care proposals, such as cutbacks in Medicare and Medicaid
coverage and reimbursement for pharmaceuticals, could adversely affect the
Company. There can be no assurance that past, present or future proposals for
health care reform, or other changes in the administration or interpretation of
governmental health care programs, will not have an adverse effect on the
Company.
 
PRODUCT LIABILITY
 
    The testing and marketing of pharmaceuticals entail an inherent risk of
product liability attributable to unwanted and potentially serious health
effects. The Company intends to obtain clinical trial liability insurance
coverage in an amount consistent with industry practice. However, there can be
no assurance that such insurance coverage is or will continue to be adequate. In
addition, the Company has product liability insurance in India, the only country
in which its products are currently being marketed. As its products achieve
wider-spread commercialization, the Company intends to seek product liability
insurance coverage in amounts consistent with industry practice in those
countries in which its products are to be marketed. There can be no assurance,
however, that insurance will be available at all or in sufficient amounts to
protect the Company at a reasonable cost.
 
FACILITIES
 
    The Company currently leases approximately 2,000 square feet of office space
in San Jose, California. The lease has a three-year term, which commenced in
October 1995, and provides for a monthly rental payment of approximately $3,200.
Bio-Ved leases approximately 1,550 square feet of office space in Pune, India
under a three-year lease expiring in May 1999. The annual rental payment is
approximately $15,000. In addition, Bio-Ved currently utilizes approximately
4,000 square feet of laboratory space provided by the Bharati Vidyapeeth's Pune
College of Pharmacy. The laboratory space is provided pursuant to a five-year
agreement which expires in 1999 under which the Company has agreed to pay an
aggregate of approximately $7,000 annually to fund research fellowships and as a
grant to the College. The Company intends to use proceeds from the Offering to
establish and equip additional laboratory facilities for its research and
development activities in India and believes that there is an adequate supply of
suitable space in the Pune region for its expansion needs.
 
EMPLOYEES
 
    As of September 30, 1997, the Company had 22 employees, 15 of whom were
engaged in research and development activities and seven are in executive
management and marketing. The Company's employees
 
                                       43
<PAGE>
are not governed by any collective bargaining agreement and the Company believes
that its relationship with its employees is good.
 
MEDICAL/SCIENTIFIC ADVISORY BOARD
 
    The Company intends to form an Advisory Board from a multidisciplinary group
of distinguished scientists representing different fields closely associated
with the Company's business. Most of the prospective members will come from the
existing consultants to the Company and will be supplemented by one or more
representatives yet to be recruited.
 
CONSULTANTS
 
    The Company utilizes various consultants in India and in the United States
for research and development of drug candidates, as well as for discovering
potential new drug candidates. The Company confers with such consultants as
necessary to discuss details of specific projects. Certain of the listed
consultants have entered into agreements specifying the terms and scope of their
individual consulting relationship with the Company. The Company does not
believe that termination of any individual agreement would materially adversely
affect its business. Although all these consultants have entered into
confidentiality agreements, none of these individuals is employed by the Company
and, therefore, they may have commitments to, or consulting contracts with,
other entities which may compete with their obligations to the Company. The

STOCK OPTIONS
 
    1997 STOCK OPTION PLAN
 
    In November 1997, the Board of Directors adopted and the stockholders
approved the 1997 Stock Option Plan (the "Option Plan"). The Option Plan
provides for the grant of incentive stock options ("ISOs") (within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"))
and non-qualified stock options ("NQSOs") to certain directors, officers,
employees and consultants of the Company. The purpose of the Option Plan is to
attract and retain exemplary employees, agents, consultants and directors.
Options granted under the Option Plan may not be exercisable for terms in excess
of 10 years from the date of grant. In addition, no options may be granted under
the Option Plan later than 10 years after the Option Plan's effective date.
Pursuant to the terms of the Option Plan, 227,986 shares of Common Stock have
been reserved for issuance upon the exercise of options granted or available for
grant under the Option Plan. Any shares subject to an option that terminates,
expires or lapses for any reason, and any shares purchased pursuant to an option
and subsequently repurchased by the Company pursuant to the terms of the option,
shall again be available for grant under the Option Plan. As of the date of this
Prospectus, a total of 45,000 options under the Option Plan, or 15,000 options
per director, have been granted to three of the Company's non-employee
directors, which options will be exercisable, at a price equal to the Offering
price, for a period of five years (vesting at the rate of one-third per year),
commencing as of November 25, 1997. No other options have yet been granted under
the Option Plan.
 
    The Option Plan will be administered by the Board of Directors of the
Company which will determine, in its discretion, among other things, the
recipients of grants, whether a grant will consist of ISOs or NQSOs, or a
combination thereof, and the number of shares of Common Stock to be subject to
such options. The Board of Directors of the Company may, in its discretion,
delegate its power, duties and responsibilities under the Option Plan to a
committee consisting of two or more directors who are "disinterested persons"
within the meaning of Rule 16b-3 promulgated under the Exchange Act. The
Compensation and Stock Option Committee is responsible for administering the
Option Plan. Options may not be granted under the Option Plan with an exercise
price which is less than the market price per share on the date of grant.
 
    The Option Plan contains certain limitations applicable only to ISOs granted
thereunder. To the extent that the aggregate fair market value, as of the date
of grant, of the shares to which ISOs become
 
                                       49
<PAGE>
exercisable for the first time by an optionee during the calendar year exceeds
$100,000, the ISO will be treated as a NQSO. In addition, if an optionee owns
more than 10% of the Company's stock at the time the individual is granted an
ISO, the option price per share cannot be less than 110% of the fair market
value per share and the term of the option cannot exceed five years.
 
    OPTION GRANTS OUTSIDE OF THE OPTION PLAN
 
    As of the date of this Prospectus, the Company has granted options outside
of the Option Plan for the purchase of an aggregate of 315,970 shares of Common

in three equal annual installments thereafter), 60,000 shares at $3.00 per share
(vesting in twelve equal three-month installments commencing December 15, 1998),
and 10,000 shares at $3.00 per share (vesting in three equal annual installments
commencing January 1, 1998), granted to Barry Wald, Nina Renaud and Ajit Chitre,
respectively, each an executive officer or significant employee of the Company.
The other 108,469 options granted are exercisable at various per share prices
ranging from $3.00 to the initial public offering price per share, commencing at
various times beginning immediately.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company has included in its Certificate of Incorporation provisions to
indemnify its directors and officers to the extent permitted by Delaware law.
The Company's Certificate of Incorporation also includes provisions to eliminate
the personal liability of its directors and officers to the Company and its
stockholders to the fullest extent permitted by Delaware law. Under current law,
such exculpation would extend to an officer's or director's breaches of
fiduciary duty, except for (i) breaches of such person's duty of loyalty, (ii)
those instances where such person is found not to have acted in good faith and
(iii) those instances where such person received an improper personal benefit as
the result of such breach.
 
    The Company's bylaws provide that the Company may indemnify any person,
including officers and directors, with regard to any action or proceeding to the
fullest extent permitted under Delaware law.
 
    The Company will enter into an Indemnification Agreement ("Indemnification
Agreement") with each of its directors and officers. Each Indemnification
Agreement will provide that the Company will indemnify the indemnitee against
expenses, including reasonable attorneys' fees, judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with any civil or criminal action or administrative proceeding
arising out of his or her performance of his or her duties as a director or
officer, other than an action instituted by the director or officer. Such
indemnification is available if the indemnitee acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action, had no
reasonable cause to believe his or her conduct was unlawful. Each
Indemnification Agreement also will require that the Company indemnify the
director or other party thereto in all cases to the fullest extent permitted by
director or officer that is party thereto to bring suit to seek recovery of
amounts due under such Indemnification Agreement and will require that the
Company indemnify the director or other party thereto in all cases to the
fullest extent permitted by applicable law. Although the Company intends to seek
to obtain directors' and officers' liability insurance, such insurance is
generally very expensive. If the Company is not able or willing to obtain
director' and officers' liability insurance to cover amounts, if any, required
to be indemnified by the Company, any payments made by the Company under an
Indemnification Agreement will have an adverse impact on its earnings.
 
    It is the position of the Commission that insofar as the foregoing
provisions may be invoked to disclaim liability for damages arising under the
Securities Act, that provision is against public policy as expressed in the
Securities Act and is therefore unenforceable.

                              CERTAIN TRANSACTIONS
 
    In October 1994, the Company borrowed $250,000 from Fred Kassner, a
principal stockholder of the Company, under a two-year convertible promissory
note bearing interest at prime plus 2% per annum, which was convertible into
61,050 shares of Common Stock. In April 1996, the Company borrowed an additional
$250,000 from Mr. Kassner under a 90-day promissory note bearing interest at
prime plus 2% per annum. In connection with the April 1996 loan, Mr. Kassner was
granted two-year warrants to purchase up to 125,000 shares of Common Stock at
130% of the initial public offering price per share. Effective October 31, 1997,
pursuant to the Note Conversion, the outstanding principal and accrued interest
under such notes, totaling $619,868, was converted into 154,967 shares of Common
Stock. In connection with this transaction Mr. Kassner was also granted October
1997 Warrants to purchase up to 45,000 shares of Common Stock at $4.00 per
share.
 
    In February 1995, Marathon, a principal stockholder of the Company,
purchased 166,651 shares of Common Stock from the Company for an aggregate
purchase price of $1,000,000, or $6.00 per share. Under the subscription
agreement, Marathon was granted certain anti-dilution rights. In consideration
for the waiver by Marathon of the anti-dilution rights, Marathon was granted
October 1997 Warrants to purchase up to 55,000 shares of Common Stock at $4.00
per share. Cynthia R. May, a director of the Company, is also a principal of
Marathon.
 
                                       52
<PAGE>
    At various times from January 1996 through July 1997, the Company borrowed
an aggregate principal amount of $204,700 from Sanjeev Chitre, the Chairman of
the Board of Directors and a principal stockholder of the Company, under a
promissory note bearing interest at prime plus 2% per annum payable
semi-annually. Originally, the note was to become due on demand, in stages, at
various times from January 1997 to July 1998. In December 1997, the terms of the
loan were revised to provide that no amounts would become due and payable
thereunder until one year following the consummation of the Offering. The
Company has allocated no proceeds of the Offering to repayment of the loan.
 
    In January 1996, Mr. Irwin Rosenthal, Secretary of the Company and husband
of Ms. Suzanne Rosenthal, a director of the Company, loaned the Company $25,000,
as evidenced by a promissory note bearing an annual interest rate of prime plus
2%. Originally, the note was to become due and payable on demand commencing
January 1997. Mr. Rosenthal was a director of the Company at the time of the
loan. In December 1997, the terms of the loan were revised to provide that no
amounts would become due and payable thereunder until one year following the
consummation of the Offering. The Company has allocated no proceeds of the
Offering to the repayment of this loan.
 
    Mr. Rosenthal is also a partner of Rubin Baum Levin Constant & Friedman
("RBLC&F"), counsel to the Company. The Company incurred expenses of
approximately $22,000, $68,000 and $39,000 for the years ended December 31, 1995
and 1996 and the nine months ended September 30, 1997, respectively, for legal
services rendered by such firm during such periods. In addition, RBLC&F
contributed services to the Company valued at approximately $128,000 in the
aggregate over such periods. The Company paid to RBLC&F a total of $5,000, $0
and $25,000 during the years ended December 31, 1995 and 1996 and the nine
months ended September 30, 1997, respectively. At September 30, 1997,
approximately $144,000 was owed by the Company to RBLC&F. See "Legal Matters."
 
    In each of March 1996 and August 1997, Michael R. Splinter, a director of
the Company, and his wife, Patricia Robestoff, loaned the Company $100,000, as
evidenced by promissory notes each bearing an annual interest rate of prime plus
2%. In connection with the loans, these individuals were granted two-year
warrants to purchase up to 100,000 shares of Common Stock at 130% of the initial
public offering price per share. Effective October 31, 1997, the outstanding
principal and accrued interest under such notes, totaling $218,964, was
converted into 54,741 shares of Common Stock in connection with the Note
Conversion.
 
    At various times from November 1996 through September 1997, the Company
borrowed an aggregate principal amount of $500,000 from the Atlantic Bank under
three-month term notes bearing interest at Atlantic Bank's prime rate plus 2%
per annum, payable monthly. The notes have been consolidated and are presently
due on February 2, 1998. The Atlantic Bank loan is guaranteed by Sanjeev and
Deepa Chitre and secured by a pledge of common stock of another company, which
stock is owned by the Avantika Sanjeev Chitre Irrevocable Trust, dated July 8,
1991, Bruce W. McRoy, trustee (the "Avantika Trust"), a trust for the benefit of
Sanjeev and Deepa Chitre's minor daughter. The Company intends to use proceeds
from the Offering to repay this loan.
 
    Effective upon the inception of Bio-Ved in November 1995, all of the
outstanding stock of Bio-Ved was registered in the names of Mr. Sanjeev Chitre's
sister, Anita Chitre, and her husband, Ajit Chitre, Managing Director of
Bio-Ved, both of whom are resident Indians. The stock was registered in the
names of these individuals pending compliance with Indian regulatory
requirements applicable to AyurCore, Inc.'s investment in Bio-Ved. Currently,
and as a result of such investment, Bio-Ved is owned more than 99% by AyurCore,
Inc. with the balance being owned by Mr. and Mrs. Ajit Chitre. Since January
1995, Mr. Ajit Chitre has been compensated for services rendered in connection
with the Company's India operations at the rate of approximately $9,000 per
year.

                           DESCRIPTION OF SECURITIES
 
GENERAL
 
    The Company's authorized capital stock consists of 25,000,000 shares of
Common Stock, $.001 par value per share, and 5,000,000 shares of preferred
stock, $.001 par value per share (the "Preferred Stock"). As of the date of this
Prospectus, there were outstanding 2,209,702 shares of Common Stock (held by
approximately 10 holders) and no shares of Preferred Stock.
 
COMMON STOCK
 
    Holders of Common Stock are entitled to one vote for each share held of
record on each matter submitted to a vote of stockholders. There is no
cumulative voting for election of directors. Subject to the prior rights of any
series of Preferred Stock which may from time to time be outstanding, holders of
Common Stock are entitled to receive dividends ratably, when, as, and if
declared by the Board of Directors' out of funds legally available therefor and,
upon the liquidation, dissolution, or winding up of the Company, are entitled to
share ratably in all assets remaining after payment of liabilities and payment
of accrued dividends and liquidation preferences on any Preferred Stock. Holders
of Common Stock have no preemptive rights and have no rights to convert their
Common Stock into any other securities. All of the outstanding shares of Common
Stock are validly authorized and issued, fully paid, and nonassessable.
 
PREFERRED STOCK
 
    The Preferred Stock may be issued in one or more series, the terms of which
may be determined at the time of issuance by the Board of Directors, without
further action by stockholders, and may include voting rights (including the
right to vote as a series on particular matters), preferences as to dividends
and liquidation, conversion rights, redemption rights, and sinking fund
provisions. The issuance of any such Preferred Stock could adversely affect the
rights of the holders of Common Stock and, therefore, reduce the value of the
Common Stock. The ability of the Board of Directors to issue Preferred Stock
could discourage, delay, or prevent a takeover of the Company.
 
OUTSTANDING WARRANTS
 
    The Company has outstanding warrants to purchase up to an aggregate of
250,000 shares of Common Stock at a purchase price of 130% of the initial public
offering price per share. These warrants expire at various times from March 1998
to August 1999. In addition, the Company has outstanding October 1997 Warrants
to purchase up to an aggregate of 100,000 shares of Common Stock at $4.00 per
share. These warrants expire in October 2002. Subject to certain limitations and
exclusions, holders of these warrants are entitled to certain piggyback
registration rights with respect to the underlying shares.
 
DIVIDEND POLICY
 
    The Company has never paid any cash dividends on its Common Stock. The
Company anticipates that in the future, earnings, if any, will be retained for
use in the business of the Company or for other corporate purposes, and it is
not anticipated that cash dividends in respect of the Common Stock will be paid.
 
TRANSFER AGENT AND REGISTRAR
 
    American Stock Transfer & Trust Company, at 40 Wall Street, 46th Floor, New
York, New York, 10005, will serve as the Company's Transfer Agent and Registrar
for the Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon consummation of the Offering, the Company will have outstanding
3,459,702 shares of Common Stock. Of such shares, the 1,250,000 shares of Common
Stock offered hereby will be freely tradable without restriction or further
registration under the Securities Act except for any shares purchased by a
person who is or thereby becomes an affiliate of the Company, which shares will
be subject to
 
                                       54
<PAGE>
the resale limitations contained in Rule 144 promulgated under the Securities
Act. The remaining 2,209,702 shares of Common Stock are restricted securities
within the meaning of Rule 144 under the Securities Act and, in general, if held
for at least one year, will be eligible for sale in the public market in
reliance upon and subject to the limitations of Rule 144.
 
    In general under Rule 144 as currently in effect, a person (or persons whose
shares are aggregated), including a person who may be deemed to be an affiliate
of the Company as that term is defined under the Securities Act, is entitled to
sell, within any three-month period, a number of shares beneficially owned for
at least one year that does not exceed the greater of (i) one percent of the
number of the then outstanding shares of Common Stock or (ii) the average weekly
trading volume in the Common Stock during the four calendar weeks preceding such
sale. Sales under Rule 144 are also subject to certain requirements as to the
manner of sale, notice and the availability of current public information about
the Company. Furthermore, a person who is not deemed to have been an affiliate
of the Company during the ninety days preceding a sale by such person and who
has beneficially owned such shares for at least two years is entitled to sell
such shares without regard to the volume, manner of sale or notice requirements.
Under Rule 144 (and subject to the conditions thereof), of the 2,209,702 shares
of Common Stock outstanding as of the date of this Prospectus, 619,850 are
eligible for sale immediately, 1,380,144 are held by affiliates of the Company
and will become eligible for sale beginning 90 days after the date of this
Prospectus; and substantially all of the remaining 209,708 shares will become
eligible for sale as of October 31, 1998. Notwithstanding the foregoing, the
holders of all of such shares have agreed, subject to certain limited
exceptions, not to offer, sell, assign, pledge or transfer any of such shares
for a period of 12 months from the date of this Prospectus without the
Representative's prior written consent. In addition, the Company has granted
certain registration rights with respect to the 125,000 and 100,000 shares of
Common Stock underlying the Representative's Warrants and the October 1997
Warrants, respectively, commencing one year following the date of this
Prospectus. See "Underwriting."
 
    Under Rule 701 of the Securities Act, persons who purchase shares upon the
exercise of options granted prior to the effective date of the Offering are
entitled to sell such shares 90 days after the effective date of the Offering
and in reliance on Rule 144 without having to comply with the holding period
requirements of Rule 144 and, in the case of nonaffiliates, without having to
comply with the public information, volume limitation, or notice provisions of
Rule 144.
 
    Prior to the Offering, there has been no public market for the Company's
securities. Following the Offering, the Company cannot predict the effect, if
any, that market sales of the Common Stock, or the availability of such shares
for sale, will have on the market price prevailing from time to time.
Nevertheless, sales by the existing stockholders of substantial amounts of
Common Stock in the public market could adversely affect prevailing market
prices for the Company's securities. In addition, the availability for sale of
substantial amounts of Common Stock acquired through the exercise of options or
warrants could adversely affect prevailing market prices for the Common Stock.

offered pursuant to the over-allotment option) if any shares are purchased. The
shares of Common Stock are being offered by the Underwriters, subject to prior
sale, when, as and if delivered to and accepted by the Underwriters and subject
to approval of certain legal matters by counsel and to certain other conditions.
 
    Through the Representative, the several Underwriters have advised the
Company that they propose to offer the shares of Common Stock to the public at
the public offering price set forth on the cover page of this Prospectus. The
Underwriters may allow to certain dealers who are members of the National
Association of Securities Dealers, Inc. ("NASD") concessions, not in excess of
$    per share, of which not in excess of $         per share may be reallowed
to other dealers who are members of the NASD. After the commencement of the
Offering, the public offering price, concessions and reallowance may be changed.
 
    The Company has granted the Representative an option, exercisable for 45
days following the date of this Prospectus, to purchase up to 187,500 additional
shares of Common Stock at the public offering price set forth on the cover page
of this Prospectus, less the underwriting discounts and commissions. The
Representative may exercise this option in whole or, from time to time, in part,
solely for the purpose of covering over-allotments, if any, made in connection
with the sale of the shares of Common Stock offered hereby.
 
    The Company has agreed to pay to the Representative individually, and not as
a representative of the Underwriters, a 3% nonaccountable expense allowance,
$50,000 of which has been paid as of the date of this Prospectus. The Company
has also agreed to pay all expenses in connection with qualifying the shares of
Common Stock offered hereby for sale under the laws of such states as the
Representative may designate, including expenses of counsel retained for such
purpose by the Representative.
 
    The Company has agreed to issue to the Representative and its designees, for
an aggregate of $125, the Representative's Warrants to purchase up to 125,000
shares of Common Stock, at an exercise price of $         per share (135% of the
initial public offering price per share). The Representative's Warrants may not
be transferred for one year following the date of this Prospectus, except to the
officers and partners of the Representative or the Underwriters or members of
the selling group, and are exercisable at any time, and from time to time,
during the four-year period commencing one year following the date of this
Prospectus (the "Warrant Exercise Term"). During the Warrant Exercise Term, the
holders of the Representative's Warrants are given, at nominal cost, the
opportunity to profit from a rise in the market price of the Common Stock. To
the extent that the Representative's Warrants are exercised or exchanged,
dilution to the interests of the Company's stockholders will occur. Further, the
terms upon which the Company will be able to obtain additional equity capital
may be adversely affected since the holders of the Representative's Warrants can
be expected to exercise them at a time when the Company would, in all
likelihood, be able to obtain any needed capital on terms more favorable to the
Company than those provided in the Representative's Warrants. Any profit
realized by the Representative on the sale of the Representative's Warrants or
the underlying shares of Common Stock may be deemed additional underwriting
compensation. Subject to certain limitations and exclusions, the Company has
agreed to register, at
 
                                       56
<PAGE>
the request of the holders of a majority of the Representative's Warrants and at
the Company's expense, the Representative's Warrants and the shares of Common
Stock underlying the Representative's Warrants under the Securities Act on one
occasion during the Warrant Exercise Term and to include such Representative's
Warrants and such underlying shares in any appropriate registration statement
that is filed by the Company during the seven years following the date of this
Prospectus.
 
    In addition, the Company has agreed to enter into a consulting agreement to
retain the Representative as a financial consultant for a period of two years
from the consummation of this Offering at an annual fee of $15,000, the entire
$30,000 payable in full, in advance. The consulting agreement will not require
the consultant to devote a specific amount of time to the performance of its
duties thereunder. In the event that the Representative originates an
acquisition or merger transaction to which the Company is a party, the
Representative will also be entitled to receive a finder's fee in consideration
for origination of such transaction.
 
    The Company has also agreed, for a period of five years following
consummation of the Offering, if so requested by the Representative, to nominate
and use its best efforts to elect a designee of the Representative as a director
of the Company, or, at the Representative's option, as a non-voting adviser to
the Company's Board of Directors. The Company's officers, directors and
stockholders have agreed to vote their shares in favor of such designee. The
Representative has not yet exercised its right to designate such a person.
 
    All of the Company's officers, directors and stockholders have agreed that,
for the 12-month period following the date of this Prospectus, they will not,
subject to certain limited exceptions, directly or indirectly sell, offer for
sale, transfer, pledge or otherwise dispose of any securities of the Company or
exercise any registration rights relating to any securities of the Company,
without the prior written consent of the Representative.
 
    The Representative has informed the Company that the Underwriters do not
intend to sell any of the shares of Common Stock offered hereby to discretionary
accounts.
 
    The Company has agreed to indemnify the Underwriters against certain civil
liabilities in connection with the Registration Statement of which this
Prospectus forms a part, including liabilities under the Securities Act.
 
    Prior to the Offering, there has been no public market for the Common Stock.
Consequently, the initial public offering price of the shares of Common Stock
will be determined by negotiation between the Company and the Representative and
may not necessarily relate to the Company's asset value, net worth or other
established criteria of value. Among the factors that will be considered in
determining the offering price are the Company's financial condition and
prospects, management, market prices of similar securities of comparable
publicly-traded companies, certain financial and operating information of
companies engaged in activities similar to those of the Company and the general
condition of the securities market.
 
    In connection with the Offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created by the Underwriters in connection with the Offering. Stabilizing
transactions consist of certain bids or purchases for the purpose of preventing
or retarding a decline in the market price of the Common stock; and syndicate
short positions created by the Underwriters involve the sale by the Underwriters
of a greater number of securities than they are required to purchase from the
Company in the Offering. The Underwriters also may impose a penalty bid, whereby
selling concessions allowed to syndicate members or other broker-dealers in
respect of the securities sold in the Offering for their account may be
reclaimed by the syndicate Underwriters if such shares of Common Stock are
repurchased by the syndicate Underwriters in stabilizing or covering
transactions. These activities may stabilize, maintain or otherwise affect the
market price of the Common Stock, which may be higher than the price that might
otherwise prevail in the open market; and these activities, if commenced, may be
discontinued at any time. These transactions may be effected on Nasdaq, the
over-the-counter market or otherwise.
 
                                       57
<PAGE>
    The Underwriters may also place bids or purchase shares to reduce a short
position created in connection with the Offering. Short positions are created by
persons who sell shares which they do not own in anticipation of purchasing
shares at a lower price in the market to deliver in connection with the earlier
sale. Short positions tend to place downward pressure on the market price of a
stock.
 
    The Representative and/or the Underwriters may impose a penalty bid by
reclaiming the selling concession to be paid to an Underwriter or selected
dealer when the securities sold by the Underwriter or selected dealer are
purchased to reduce a short position created in connection with the Offering.
 
    The Representative was organized in February 1992 and registered as a
broker-dealer with the Commission and the NASD, in 1993. Prior to the Offering,
the Representative has acted as a principal underwriter in six public offerings.
 
    The Commission is conducting an investigation concerning various aspects of
the Representative's compliance with the Federal securities laws. The
Representative cannot predict whether this investigation will ever result in any
type of action against the Representative, or, if so, whether any such action
might have an adverse effect on the Representative or the securities offered
hereby. The Company has been advised that the Representative intends to make a
market in the securities following the Offering. An unfavorable resolution of
the Commission's investigation could have the effect of limiting the
Representative's ability to make a market in the Company's securities, which
could affect the liquidity or price of such securities.
 
                                 LEGAL MATTERS
 
    Certain legal matters in connection with the issuance of the securities
offered hereby will be passed upon for the Company by Rubin Baum Levin Constant
& Friedman, New York, New York. Irwin M. Rosenthal, a partner of Rubin Baum
Levin Constant & Friedman, is Secretary of the Company, is married to Ms.
Suzanne Rosenthal, a director of the Company, and owns 172,518 shares of Common
Stock. Mr. Rosenthal rendered legal services to the Company in connection with
the Offering. Nishith Desai Associates has served as special counsel to the
Company in connection with matters related to the laws of India. Tenzer
Greenblatt, LLP, New York, NY, will pass upon certain legal matters for the
Underwriter.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
AyurCore, Inc.
 
    We have audited the accompanying combined balance sheet of AyurCore, Inc.
and Bio-Ved Pharmaceuticals Private Limited, an entity organized in India,
(collectively, the "Company", a development stage enterprise), as of December
31, 1996, and the related combined statements of operations, changes in capital
deficiency and cash flows for each of the two years in the period ended December
31, 1996 and for the period January 11, 1993 (inception) through December 31,
1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements enumerated above present fairly, in
all material respects, the combined financial position of AyurCore, Inc. and
Bio-Ved Pharmaceuticals Private Limited as of December 31, 1996 and the combined
results of their operations and their combined cash flows for each of the years
in the two-year period ended December 31, 1996 and for the period January 11,
1993 (inception) through December 31, 1996 in conformity with generally accepted
accounting principles.
 
    The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note A to the
financial statements, the Company has sustained recurring losses, a working
capital deficiency, negative cash flows from operating activities and
shareholders' capital deficiency that raise substantial doubt about its ability
to continue as a going concern. Management's plans in regard to these matters
are also described in Note A. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.
 
    As described in Note N[1], in October 1997 AyurCore, Inc. invested in
Bio-Ved Pharmaceuticals Private Limited and obtained substantially all of its
common stock.

                         NOTES TO FINANCIAL STATEMENTS
 
 (INFORMATION WITH RESPECT TO SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
            SEPTEMBER 30, 1996 AND SEPTEMBER 30, 1997 IS UNAUDITED)
 
NOTE A--THE COMPANY
 
    AyurCore, Inc. was incorporated in Delaware on January 11, 1993. In October
1997, AyurCore, Inc. obtained substantially all of the common stock of Bio-Ved
Pharmaceuticals Private Limited ("Bio-Ved"), an Indian company. From inception,
November 8, 1995, Bio-Ved was solely funded by AyurCore, Inc. and, accordingly,
the accompanying financial statements include the accounts of Bio-Ved (which
accounts reflect net losses for the year ended December 31, 1996 and the nine
month period ended September 30, 1997, respectively). Effective November 1995,
Bio-Ved was wholly owned by relatives of the majority stockholders of AyurCore,
Inc. See Note N[1].
 
    AyurCore, Inc. and Bio-Ved (collectively, the "Company") are engaged in the
discovery, development, clinical testing and marketing of proprietary
plant-based pharmaceuticals (phyto-pharmaceuticals) for the treatment of
chronic, difficult-to-treat human diseases, applying the principles of Ayurveda
(an ancient science native to India which uses plants as medicinal therapies).
Substantially all the Company's operations relating to Ayurvedic drugs are being
conducted in India and certain of the Company's products require raw materials
which are indigenous to India. The Company is in the development stage and, to
date, has not generated any significant sales, has incurred expenses and has
sustained losses. Consequently, its operations are subject to all the risks
inherent in the establishment of a new business enterprise.
 
    For the period from inception through December 31, 1996, the Company has
accumulated a deficit of $3,421,000, and has been dependent upon advances and
loans from shareholders. These factors raise substantial doubt about the
Company's ability to continue as a going concern. In order to continue its
operations, the Company is seeking additional financing, which it is endeavoring
to do by means of a public offering of securities (see Note J[5]). However,
there is no assurance that the Company can complete its proposed securities
offering or that it can obtain adequate additional financing from other sources
or that profitable operations can be attained. The financial statements do not
include any adjustments relating to the recoverability of recorded asset amounts
or the amount and classification of liabilities that might be necessary as a
result of the above uncertainty.
 
    Foreign investments in Indian companies are subject to currency exchange
control laws. Such laws may restrict the repatriation of income earned by, and
capital invested in, such subsidiaries. However, future funding of investments
may be repatriated provided the Company receives approval from the governmental
agency responsible for administering the currency controls for which an
application has been filed.
 
    In addition, the Indian government prohibits the export of certain plants,
plant portions and their derivatives and extracts.
 
NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
[1] BASIS OF PRESENTATION:
 
    The accompanying combined financial statements include the accounts of
AyurCore, Inc. (including its Indian liaison office) and Bio-Ved Pharmaceuticals
Private Limited (a company organized in India).

 (INFORMATION WITH RESPECT TO SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
            SEPTEMBER 30, 1996 AND SEPTEMBER 30, 1997 IS UNAUDITED)
 
NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
[1] BASIS OF PRESENTATION: (CONTINUED)
Subsequent to September 30, 1997 Bio-Ved became a substantially wholly-owned
subsidiary. All material intercompany transactions and account balances have
been eliminated in combination.
 
[2] INVENTORY:
 
    Inventory consists of raw materials and is stated at the lower of cost
(first-in, first-out method) or market.
 
[3] EQUIPMENT:
 
    Equipment is carried at cost. Depreciation is provided using the
straight-line method over the estimated useful lives of the assets which range
from three to five years. Leasehold improvements are amortized over the lesser
of the economic useful life of the improvement or term of the lease whichever is
shorter.
 
[4] RESEARCH AND DEVELOPMENT AND PATENTS:
 
    Research and development costs and patent expenses are charged to operations
as incurred.
 
[5] USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
[6] LOSS PER SHARE OF COMMON STOCK:
 
    Net loss per share of common stock is based on the weighted average number
of shares outstanding during each period, as modified in accordance with certain
rules of the Securities and Exchange Commission. Accordingly, the weighted
average number of shares outstanding during each period includes options issued
twelve months prior to the Company's proposed initial public offering at a price
below the anticipated initial public offering price ($6.00) using the treasury
stock method as if they were outstanding for all periods.
 
[7] FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
    The carrying value of cash, notes payable, and trade payables and accrued
expenses approximates the fair value because of the short maturity of those
instruments.

NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
[8] FOREIGN CURRENCY:
 
    The financial statements for the operations in India are translated into
U.S. dollars from the Company's functional currency (Indian Rupee) at year end
exchange rates for assets and liabilities and weighted average exchange rate for
revenue and expenses. The effect of foreign currency translation adjustments are
included as a component of capital deficiency. Such amounts for the periods
presented were not material.
 
[9] STOCK-BASED COMPENSATION:
 
    Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("SFAS No. 123") encourages, but does not require,
companies to record compensation cost for stock-based employee compensation
plans at fair value. The Company has elected to account for its employee
stock-based compensation plans using the intrinsic value method prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB No. 25"). Under the provisions of APB No. 25, compensation cost
for stock options is measured as the excess, if any, of the quoted market price
of the Company's common stock at the date of the grant over the amount an
employee must pay to acquire the stock. Stock options granted to nonemployees
for goods or services are measured using the fair value of these options and
such costs are included in operating results as an expense.
 
[10] REVENUE RECOGNITION:
 
    Sales revenue is recognized when product is shipped. Grant revenues are
recognized as the expenses for research and development activities performed
under the terms of the grant award are incurred.
 
[11] INTERIM FINANCIAL INFORMATION:
 
    The financial statements at September 30, 1997 and for the nine months ended
September 30, 1996 and 1997 are unaudited, but include all adjustments
(consisting only of normal recurring adjustments) which management considers
necessary for a fair presentation of financial position, results of operations
and cash flows for those periods. Results of interim periods are not necessarily
indicative of results for the entire year or any future periods.
 
[12] RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS:
 
    In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share", which is required to be adopted for the year
ending December 31, 1997. At that time, the Company will be required to change
the method used to compute loss per share. The Company has not determined the
impact on adoption of this accounting standard
 
    In June 1997, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 129, "Disclosure of Information about Capital
Structure", No. 130, "Reporting Comprehensive Income", and No. 131, "Disclosures
about Segments of an Enterprise and Related Information". The

NOTE D--INVESTMENTS
 
    The Company accounts for its investments based on the following categories:
(1) held-to-maturity; (2) available for sale and (3) trading investments.
Held-to-maturity investments at September 30, 1997 consist of interest bearing

NOTE F--INCOME TAXES
 
    The Company recognizes deferred tax assets and liabilities for the future
tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases.
 
    As of December 31, 1996, the Company has available for tax purposes the
following net operating loss carryforwards, utilizable against the taxable

    At December 31, 1996, the Company has provided a valuation reserve against
the full amount of its net operating loss benefit of approximately $1,180,000
(including $40,000 net operating loss benefit arising from Indian operations
which may only be utilized against future Indian taxable income) and the benefit
of $200,000 from other temporary differences, principally compensation expense
not currently deductible, since the likelihood of realization cannot be
determined.
 
    A reconciliation between the actual income tax benefit and income taxes
computed by applying the United States federal income tax rate of 34% to the net
loss is as follows:

    The Internal Revenue Code contains provisions which may limit the
utilization of the net operating loss carryforward available in any given year
if significant changes occur in shareholder ownership interests. If the proposed
public offering discussed in Note J[5] to the financial statements is
consummated, it is probable that the amount of carryforward available in any
given year will be limited.

NOTE J--CAPITAL DEFICIENCY
 
[1] STOCK SPLIT AND CHANGE IN CAPITAL:
 
    On November 18, 1997, the Board of Directors of the Company approved an
18,333.486-for-1 stock split of its common stock. In addition, the Board of
Directors increased the authorized shares to 25,000,000 shares of common stock
and 5,000,000 shares of preferred stock. All per share and share amounts in the
accompanying financial statements have been retroactively adjusted to reflect
the stock split.
 
[2] COMMON STOCK:
 
    On November 18, 1997 the Board of Directors of the Company approved the
reclassification of its Class A and Class B common stock into one class of
common stock. The accompanying financial statements present common stock on the
converted basis.
 
    A subscription agreement for the purchase of 166,651 shares of common stock
for $1,000,000 contains an antidilution provision on the next subscription for
the same class of stock which is at a per share price less than $6.00.
 
[3] WARRANTS:
 
    In connection with certain notes payable issued during the year ended
December 31, 1996 and nine months ended September 30, 1997 (see Note I), the
Company issued warrants for the purchase of 200,000 and 50,000 shares,
respectively, of common stock at an exercise price of 130% of the initial public
offering price, expiring through August 1999.
 
[4] STOCK OPTIONS:
 
    Pro forma information regarding net loss and loss per share is required by
SFAS No. 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that statement. The fair
value of options granted to employees during the year ended December 31, 1996 is
estimated to be $1.37 per share. The fair value of these options was estimated
at the date of grant using the Black-Scholes option pricing model with the
following weighted average assumptions for the year ended December 31, 1996:
risk free interest rate of 6.64%-6.73%; dividend yield of 0%; volatility of 40%
and expected life for options granted of 5 years.
 
    The fair value of options granted during the nine months ended September 30,
1996 and September 30, 1997 is estimated at $1.37 and $2.14, respectively. The
fair value on the grant date was computed using the Black-Scholes option pricing
model with the following assumptions for the nine months ended September 30,
1996 and September 30, 1997: dividend yield of 0%; volatility of 40%; risk free
interest rate of 6.64%-6.73% and 5.5%, respectively, and expected life for
options granted of 5 years in 1996 and 1997.
 
    During the year ended December 31, 1996 the Company issued options for
29,000 shares of common stock to consultants which were valued at $39,000 and
are being amortized over the period of the related agreements.

NOTE J--CAPITAL DEFICIENCY (CONTINUED)
 
[4] STOCK OPTIONS: (CONTINUED)
    Management has determined that the pro forma effects for employee
stock-based compensation under SFAS No. 123 would not be significant to net loss
or net loss per share for the year ended December 31, 1996 and for the nine
months ended September 30, 1996 and September 30, 1997. Accordingly, such pro
forma information is not presented herein.
 
    Through December 31, 1994 the Company has granted 261,252 options to
employees at exercise prices less than the fair value of the underlying common
stock at the dates of grant. The Company recorded the difference as unearned
compensation, which is being amortized over the vesting period.
 
    During the nine months ended September 30, 1997 the Company granted 60,000
options to an employee at an exercise price which is $1.00 below the fair value
of the underlying common stock. The Company recorded the difference as unearned
compensation, which is being amortized over the vesting period.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES.
 
    Set forth below is information as to securities of the Registrant sold
within the past three years which were not registered under the Securities Act
of 1933, as amended (the "Act"). In connection with such sales, the Registrant
relied upon the exemption from registration provided by Section 4(2) of the Act.
All purchasers have represented that they are accredited investors. The
information below gives effect to (i) the reclassification of the Registrant's
Class A Common Stock and Class B Common Stock as a single class of Common stock
and (ii) a stock split effected November 26, 1997, pursuant to which each
outstanding share of common stock was reclassified and converted into 18,333.486
shares of Common Stock.
 
    On February 3, 1995, Marathon Investments L.L.C. purchased 166,651 shares of
Common Stock of the Registrant at a purchase price of $1,000,000.
 
    From March 1996 to August 1997, the Company issued warrants to purchase
250,000 shares of Common Stock to three lenders in connection with their loans
to the Company in the aggregate amount of $500,000. Each warrant entitles the
holder to purchase one share of Common Stock at a price equal to 130% of the
initial public offering price per share for a period of two years.
 
    Effective October 31, 1997, two holders of debt aggregating $838,830 in
principal and accrued interest (the "Debt") converted the Debt into an aggregate
of 209,708 shares of Common Stock of the Registrant. In addition, effective
December 8, 1997, the Company approved the issuance of 45,000 warrants to one of
such holders in connection with the Debt conversion, as well as 55,000 warrants
to another stockholder of the Company in consideration for the release of
certain antidilution rights. Each warrant entitles the holder to purchase one
share of common stock at $4.00 per share for a period of five years.

ITEM 28. UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes to provide to the
Underwriter at the closings specified in the Underwriting Agreement certificates
in such denominations and registered in such names as required by the
Underwriter to permit prompt delivery to each purchaser of the Common Stock
offered hereby.
 
    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    (c) The 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.

L.T. Lawrence & Co., Inc.
  as Representative of the
  Several Underwriters named
  in Schedule A hereto
3 New York Plaza
New York, New York 10004

Dear Sirs:

          AyurCore, Inc., a Delaware corporation (the "Company"), proposes to
issue and sell to the underwriters (the "Underwriters") named in Schedule A to
this Underwriting Agreement (the "Agreement"), for whom LT Lawrence & Co., Inc.
(the "Representative") is acting as representative, one million two hundred and
fifty thousand (1,250,000) shares of common stock, par value $.001 per share
(the "Offered Shares"), which Offered Shares are presently authorized but
unissued shares of the common stock, par value $.001 per share (individually a
"Common Share" and collectively the "Common Shares"), of the Company.  In
addition, the Representative, in order to cover over-allotments in the sale of
the Offered Shares, may purchase from the Company, for its own account, up to an
aggregate of one hundred eighty-seven thousand five hundred (187,500) Common
Shares (the "Optional Shares"; the Offered Shares and the Optional Shares are
hereinafter sometimes collectively referred to as the "Shares").  The Shares are
described in the Registration Statement, as defined below.  The Company also
proposes to issue and sell to the Representative for its own account and/or the
accounts of its designees, warrants to purchase an aggregate of one hundred
twenty-five thousand (125,000) Common Shares (the "Warrant Shares") at an
exercise price of $____ per Warrant Share [135% of the initial public offering
price per Share] (the "Representative's Warrants"), which sale will be
consummated in accordance with the terms and conditions of the form of
Representative's Warrant Agreement filed as an exhibit to the Registration
Statement.

<PAGE>

         The Representative hereby warrants to the Company that it has been
authorized by each of the Underwriters to enter into this Underwriting Agreement
on their behalf and to act for them in the manner herein provided.  The Company
hereby confirms its respective agreements with the Representative and each of
the Underwriters, on whose behalf the Representative is signing this Agreement,
as follows:

         1.   Purchase and Sale of Offered Shares.  On the basis of the
representations and warranties herein contained, but subject to the terms and
conditions herein set forth, the Company hereby agrees to sell the Offered
Shares to the Underwriters, severally, and each Underwriter agrees severally and
not jointly, to purchase from the Company, at a purchase price of $____ per
share, the number of Offered Shares set forth opposite the name of such
Underwriter in Schedule A attached hereto, plus any additional Offered Shares
which such Underwriter may become obligated to purchase pursuant to the
provisions of Section 10 hereof.  The Underwriters plan to offer the Offered
Shares to the public at a public offering price of $____ per share.

         2.   Payment and Delivery.

              (a)  Payment for the Offered Shares will be made to the Company
by wire transfer against delivery of the Offered Shares to the Representative. 
Such payment and delivery will be made at 10:00 A.M. New York City time, on the
third business day following the Effective Date (the fourth business day
following the Effective Date in the event that trading of the Offered Shares
commences on the day following the Effective Date), the date and time of such
payment and delivery being herein called the "Closing Date."  The certificates
representing the Offered Shares to be delivered will be in such denominations
and registered in such names as the Representative may request not less than two
full business days prior to the Closing Date, and will be made available to the
Representative for inspection, checking and packaging at the office of American
Stock Transfer & Trust Company, the Company's transfer agent, at 40 Wall Street,
New York, New York 10005, not less than one full business day prior to the
Closing Date.

              (b)  On the Closing Date, the Company will sell the
Representative's Warrants to the Representative or to its designees (limited to
officers and partners of the Representative and/or, at the Representative's
direction, members of the selling group or underwriting syndicate participating
in the distribution of the Offered Shares and/or their respective officers or
partners).  The Representative's Warrants will be in the form of, and in
accordance with, the provisions of the Representative's Warrant Agreement
attached as an exhibit to the Registration Statement.  The aggregate purchase
price for the Representative's Warrants is $125.  

                                       2
<PAGE>

The Representative's Warrants will be restricted from sale, transfer, 
assignment, pledge or hypothecation for a period of one year from the 
Effective Date, except to officers or partners of the Representative and 
Underwriters and members of the selling group and/or their officers or 
partners.  Payment for the Representative's Warrants will be made to the 
Company by check or checks payable to its order on the Closing Date against 
delivery of the certificates representing the Representative's Warrants. The 
certificates representing the Representative's Warrants will be in such 
denominations and such names as the Representative may request prior to the 
Closing Date.

         3.   Option to Purchase Optional Shares.

              (a)  For the purposes of covering any over-allotments in
connection with the distribution and sale of the Offered Shares as contemplated
by the Prospectus as defined below, the Representative is hereby granted an
option to purchase for its own account, and not as representative of the
Underwriters, all or any part of the Optional Shares from the Company.  The
purchase price to be paid for the Optional Shares will be the same price per
Optional Share as the price per Offered Share set forth in Section 1 hereof. 
The option granted hereby may be exercised by the Representative as to all or
any part of the Optional Shares at any time within 45 days after the Effective
Date.  The Representative will not be under any obligation to purchase any
Optional Shares prior to the exercise of such option.

              (b)  The option granted hereby may be exercised by the
Representative by giving oral notice to the Company, which must be confirmed by
a letter, telex or telegraph setting forth the number of Optional Shares to be

other than under the Securities Act of 1933, as amended (the "Act"), the
Regulations (as hereinafter defined) and applicable state securities or Blue Sky
laws, are required (i) for the valid authorization, issuance, sale and delivery
of the Shares to the Underwriters, and (ii) the consummation by the Company of

              (d)  The conditions for use of a registration statement on Form
SB-2 set forth in the General Instructions to Form SB-2 have been satisfied with

and all financial schedules and exhibits thereto, as amended at the time it
becomes effective, and the final prospectus included therein are herein,
respectively, called the "Registration Statement" and the "Prospectus," except
that, (i) if the prospectus filed by the Company pursuant to Rule 424(b) of the
Regulations differs from the Prospectus, the term "Prospectus" will also include
the prospectus filed pursuant to Rule 424(b), and (ii) if the Registration
Statement is amended or such Prospectus is supplemented after the date the
Registration Statement is declared effective by the Commission (the "Effective
Date") and prior to the Option Closing Date, the terms "Registration Statement"
and "Prospectus" shall include the Registration Statement as amended or
supplemented.

              (e)  Neither the Commission nor, to the best of the Company's
knowledge, any state regulatory authority has issued any order preventing or
suspending the use of any Preliminary Prospectus or has instituted or, to the
best of the Company's knowledge, threatened to institute any proceedings with
respect to such an order.

              (f)  The Registration Statement when it becomes effective, the
Prospectus (and any amendment or supplement thereto)

documents as of the Closing Date and the Option Closing Date referred to 
below, will contain all statements which are required to be stated therein in

conform to the requirements of the Act and the Regulations, and neither the 
Registration Statement nor the Prospectus, nor any amendment or supplement 
thereto, on such dates, will contain any untrue statement of a material fact 
or omit to state any material fact required to be stated therein or necessary 
to make the statements therein, in light of the circumstances under which 
they were made, not misleading, except that this representation and warranty 
does not apply to statements or omissions made in reliance upon and in 
conformity with information furnished in writing to the Company in connection 
with the Registration Statement or Prospectus or any amendment or supplement 
thereto by the Representative, or by any Underwriter through the 
Representative, expressly for use therein.

              (g)  The Company had at the date or dates indicated in the
Prospectus a duly authorized and outstanding capitalization as set forth in the
Registration Statement and the Prospectus.  Based on the assumptions stated in
the Registration Statement and the Prospectus, the Company will have on the
Closing Date the adjusted stock capitalization set forth therein.  Except as set
forth in the Registration Statement or the Prospectus, on the Effective Date and
on the Closing Date, there will be no options to purchase, warrants or other
rights to subscribe for, or any securities or obligations convertible into, or
any contracts or commitments to issue or sell shares of the Company's capital
stock or any such warrants, convertible securities or obligations.  Except as
set forth in the Prospectus, no holder of any of the Company's securities has
any rights, "demand," "piggyback" or otherwise, to have such securities
registered under the Act.

              (h)  The descriptions in the Registration Statement and the
Prospectus of contracts and other documents are accurate and present fairly the
information required to be disclosed, and there are no contracts or other

the Registration Statement becomes effective, and thereafter from time to time
as requested, such number of copies of the Prospectus (as supplemented, if the
Company makes any supplements to the Prospectus) as each Underwriter may
reasonably request.  The Company has furnished or will furnish to the
Representative a signed copy of the Registration Statement as originally filed
and 

                                        14
<PAGE>

of all amendments thereto, whether filed before or after the Registration 
Statement becomes effective, a copy of all exhibits filed therewith and a 
signed copy of all consents and certificates of experts.

              (d)  The Company will comply with the Act, the Regulations, the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations thereunder so as to permit the continuance of sales of and
dealings in the Offered Shares and in any Optional Shares which may be issued
and sold.  If, at any time when a prospectus relating to the Shares is required
to be delivered under the Act, any event occurs as a result of which the
Registration Statement and Prospectus as then amended or supplemented would
include an untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or if it shall be necessary to amend or
supplement the Registration Statement and Prospectus to comply with the Act or
the regulations thereunder, the Company will promptly file with the Commission,
subject to Section 5(a) hereof, an amendment or supplement which will correct
such statement or omission or which will effect such compliance.

              (e)  The Company will furnish such proper information as may be
required and otherwise cooperate in qualifying the Shares for offering and sale
under the securities or Blue Sky laws relating to the offering in such
jurisdictions as the Representative may reasonably designate, provided that no
such qualification will be required in any jurisdiction where, solely as a
result thereof, the Company would be subject to service of general process or to
taxation or qualification as a foreign corporation doing business in such
jurisdiction.

              (f)  The Company will make generally available to its security
holders, in the manner specified in Rule 158(b) under the Act, and deliver to
the Representative  and Underwriters' Counsel as soon as practicable and in any
event not later than 45 days after the end of its fiscal quarter in which the
first anniversary date of the effective date of the Registration Statement
occurs, an earning statement meeting the requirements of Rule 158(a) under the
Act covering a period of at least 12 consecutive months beginning after the
effective date of the Registration Statement.

              (g)  For a period of three years from the Effective Date, the
Company will deliver to the Representative and to Underwriters' Counsel, on a
timely basis (i) a copy of each report or document, including, without
limitation, reports on Forms 8-K, 10-K (or 10-KSB) and 10-Q (or 10-QSB) and
exhibits thereto, filed or furnished to the Commission, any securities exchange
or the 

                                       15
<PAGE>

National Association of Securities Dealers, Inc. ("NASD") on the date each 
such report or document is so filed or furnished; (ii) as soon as 
practicable, copies of any reports or communications (financial or other) of 
the Company mailed to its security holders; (iii) as soon as practicable, a 
copy of any Schedule 13D, 13G, 14D-1 or 13E-3 received or prepared by the 
Company from time to time; (iv) quarterly statements setting forth such 
information regarding the Company's results of operations and financial 
position (including balance sheet, profit and loss statements and data 
regarding outstanding purchase orders) as is regularly prepared by management 
of the Company; and (v) such additional information concerning the business 
and financial condition of the Company as the Representative may from time to 
time reasonably request and which can be prepared or obtained by the Company 
without unreasonable effort or expense.  The Company will furnish to its 
shareholders annual reports containing audited financial statements and such 
other periodic reports as it may determine to be appropriate or as may be 
required by law.  

              (h)  Neither the Company nor any person that controls, is
controlled by or is under common control with the Company will take any action
designed to or which might be reasonably expected to cause or result in the
stabilization or manipulation of the price of the Common Shares.

              (i)  If the transactions contemplated by this Agreement are
consummated, the Representative shall retain the $50,000 previously paid to it,
and the Company will pay or cause to be paid the following:  all costs and
expenses incident to the performance of the obligations of the Company under
this Agreement, including, but not limited to, the fees and expenses of
accountants and counsel for the Company; the costs of preparing, printing and
delivering the Registration Statement (including financial statements and
exhibits), Preliminary Prospectuses and the Prospectus, and any amendments or
supplements thereto (all in such quantities as the Underwriters may reasonably
require); the costs of printing and delivering the Underwriting Agreement, the
Agreement Among Underwriters, the Selected Dealer Agreement and related
documents (all in such quantities as the Underwriters may reasonably require);
the costs of preparing and printing stock certificates and issuing and
delivering the Shares to the Representative; all taxes, if any, on the issuance
of the Shares; transfer agent and registrar fees; the filing fees, costs and
expenses incurred in filing and securing any required review by the Commission,
the NASD, Nasdaq and either the Boston Stock Exchange or the Pacific Stock
Exchange; the filing fees, costs and expenses incurred in qualifying the Shares
for sale under the "Blue Sky" or securities laws of those states, as specified
by the Representative, in which the Shares are to be offered or sold, including
the legal fees and disbursements of Underwriters' Counsel 

                                       16
<PAGE>

(which legal fees and disbursements, not including filing and listing fees 
paid by Underwriters' Counsel on the Company's behalf, shall not exceed 
$35,000) incurred in connection therewith, and the cost of printing and 
mailing the "Blue Sky" Survey; the cost of furnishing to the several 
Underwriters copies of the Registration Statement, Preliminary Prospectuses 
and the Prospectus as herein provided; the costs of conducting a background 
check on the two most senior executives of the Company; the costs (up to a 
maximum of $10,000) of placing "tombstone advertisements" in any publications 
which may be selected by the Representative; subject to their prior written 
approval by the Company, "road show" expenses, including related travel and 
meeting costs, and all other costs and expenses incident to the performance 
of the Company's obligations hereunder which are not otherwise specifically 
provided for in this Section 5(i).

              In addition, at the Closing Date or the Option Closing Date, as
the case may be, the Representative will deduct from the payment for the Offered
Shares and Optional Shares, as the case may be, three percent (3%) of the gross
proceeds of the offering (less the sum of $50,000 previously paid to the
Representative), as payment for the Representative's nonaccountable expense
allowance relating to the transactions contemplated hereby, which amount will
include the fees and expenses of Underwriters' Counsel (other than those payable
by the Company in connection with "Blue Sky" qualifications referred to in the
preceding paragraph). 

              (j)  If the transactions contemplated by this Agreement or 
related hereto are not consummated for any reason other than because of the 
Representative's termination of the offering for "cause" (as defined herein), 
the Company will only be obligated to reimburse the Representative for up to 
Fifty Thousand Dollars ($50,000) of the Representative's actual out-of-pocket 
expenses incurred in connection with the offering (including, without 
limitation, the reasonable fees and disbursements of Underwriters' Counsel), 
inclusive of the Fifty Thousand Dollars ($50,000) previously paid to the 
Representative (the "Advance") as part of the three percent (3%) 
nonaccountable expense allowance described in Section 5(j) above (it being 
understood that if any portion of the Advance is not needed for the 
effectuation of such reimbursement, such portion will be returned to the 
Company).  However, if the transactions contemplated herein are not 
consummated due to the Representative's termination of the offering for 
"cause" ("cause" being understood to mean a breach by the Company of any of 
the covenants, warranties or representations in this Agreement), the Company 
will be obligated to promptly reimburse the Representative for up to 
_____________________ Dollars ($______) 
[the aggregate amount of the potential three percent (3%) nonaccountable 
expense allowance described in Section 5(j) above] of its actual out-of-pocket 
expenses incurred in connection with the offering (including, without 
limitation the reasonable fees and 

                                       17
<PAGE>

disbursements of Underwriters' Counsel), inclusive of the Advance (it being 
understood that if any portion of the Advance is not needed for the 
effectuation of such reimbursement, such portion will be returned to the 
Company).  Additionally, if the transactions contemplated by this Agreement 
or related hereto are not consummated for any reason, any amounts paid by the 
Company to Underwriters' Counsel in respect of "Blue Sky" matters shall be 
retained by such counsel to the extent of its actual charges for fees and 
disbursements relating to such "Blue Sky" matters (it being understood that 
any balance remaining after payment of such fees and expenses will be 
returned to the Company).  

              (k)  The Company intends to apply the net proceeds from the sale
of the Shares for the purposes set forth in the Prospectus.  No portion of the
net proceeds from the sale of the shares will be used to repay any indebtedness
without the prior written consent of the Representative.

              (l)  During the period of twelve (12) months following the date 
hereof, without the Representative's prior written consent (i) neither the 
Company nor any of its officers, directors or securityholders will offer for 
sale, sell, contract to sell, grant an option for the sale of, issue, assign, 
transfer, pledge or otherwise dispose of, directly or indirectly, any 
securities of the Company owned by them as of the date hereof, in any manner 
whatsoever, whether pursuant to Rule 144 of the Regulations or otherwise, 
other than: (a) the grant of options pursuant to an employee stock option 
plan approved by the Representative; (b) up to 25,000 options, each to 
purchase one Common Share at $____ [the initial public offering price], 
currently owned by Dr. Richard Polisson; (c) up to 5,000, 1,250, 2,000, 
5,000, 2,500, 2,500, 750 and 3,750 options, each to purchase one Common Share 
at $3.00, currently owned by Bhushen Patwardham, Ph.D., John Graves, Ph.D., 
Subramaniam Shastri, Ph.D., Arvind Chopra, M.D., Madhu Chaubal, Ph.D., George 
Enrlich, M.D., Christine Kasik and Ajit Chitre, respectively; and (d) by bona 
fide gift, will or the laws of descent and distribution to the 
securityholder's spouse, children or grandchildren, a trust for the benefit 
of such securityholder's spouse, children or grandchildren, a partnership, 
the general partner of which is the securityholder (or a corporation, a 
majority of whose outstanding stock is owned of record or beneficially by the 
securityholder or any of the foregoing) or partners of the securityholder in 
connection with the securityholder partnership's distribution of its Common 
Shares to its partners; provided in each case that the transferee first 
executes and delivers to the Representative an undertaking to be bound by the 
provisions of this Section 5(l); and (ii) no holder of registration rights 
relating to securities of the Company will execute any such registration 
rights.  The Company will deliver to the Representative the undertakings as 
of the date hereof of its officers, directors and securityholders to this 
effect.

                                       18
<PAGE>

              (m)  The Company will not file any registration statement
relating to the offer or sale of any of the Company's securities, including any
registration statement on Form S-8, during the twelve (12) months following the
date hereof without the Representative's prior written consent.

              (n)  The Company maintains and will continue to maintain a system
of internal accounting controls sufficient to provide reasonable assurances
that: (i) transactions are executed in accordance with management's general or
specific authorization; (ii) transactions are recorded as necessary in order to
permit preparation of financial statements in accordance with generally accepted
accounting principles and to maintain accountability for assets; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

              (o)  The Company will use its best efforts to maintain the
listing or quotation of its Common Shares on the Nasdaq market for so long as
the Common Shares are qualified for such listing or quotation.

              (p)  The Company will, concurrently with the Effective Date,
register the class of equity securities of which the Shares are a part under
Section 12(g) of the Exchange Act and the Company will maintain such
registration for a minimum of five (5) years from the Effective Date.

              (q)  Subject to the sale of the Offered Shares, the
Representative and its successors will have the right to designate a nominee for
election, at its or their option, as a member of the Board of Directors of the
Company (the "Director-Designee"), and the Company will use its best efforts to
cause such Director-Designee to be elected and continued in office as a director
of the Company until the expiration of five (5) years from the Effective Date. 
Each of the Company's current officers, directors and shareholders agrees to
vote all of the Common Shares owned by such person or entity so as to elect and
continue in office such Director-Designee.  Following the election of such
Director-Designee as a director, such person shall receive no more or less
compensation than is paid to other non-employee directors of the Company for
attendance at meetings of the Board of Directors of the Company and shall be
entitled to receive reimbursement for all reasonable costs incurred in attending
such meetings including, but not limited to, food, lodging and transportation to
the same extent that other directors are reimbursed for such expenses.  If the
Representative does not exercise its option to designate a member of the
Company's Board of Directors, the Representative shall 

                                       19
<PAGE>

nonetheless have the right to have a designee of the Representative appointed 
as a non-voting advisor (the "Advisor") to the Board or to send a 
representative (who need not be the same individual from meeting to meeting) 
to observe each meeting of the Board of Directors.  The Company agrees to 
indemnify and hold the Director-Designee or the Advisor, as the case may be, 
harmless, to the maximum extent permitted by law, against any and all claims, 
actions, awards and judgments arising out of his or her service as a director 
or advisor and, in the event the Company maintains a liability insurance 
policy affording coverage for the acts of its officers and directors, to 
include the Director-Designee or the Advisor, as the case may be, as an 
insured under such policy.  The rights and benefits of such indemnification 
and the benefits of such insurance shall, to the extent possible, extend to 
the Representative insofar as it may be or may be alleged to be responsible 
for the Director-Designee or the Advisor.  The Company agrees to give the 
Representative notice of each such meeting and to provide the Representative 
and, if designated by the Representative, the Advisor, with an agenda and 
minutes of the meeting no later than it gives such notice and provides such 
items to the directors.
               
              (r)  The Company shall retain a transfer agent for the Common
Shares, reasonably acceptable to the Representative, for a period of three (3)
years following the Effective Date.  In addition, for a period of three (3)
years following the Effective Date, the Company, at its own expense, shall cause
its transfer agent to provide the Representative with copies of the Company's
daily transfer sheets and when requested by the Representative, a current list
of the Company's security holders, including a list of the beneficial owners of
securities held by a depository trust company and other nominees.

              (s)  The Company hereby agrees, at its sole cost and expense, to
supply and deliver to Underwriters' Counsel, within a reasonable period from the
date hereof, five bound volumes, including the Registration Statement, as
amended or supplemented, all exhibits to the Registration Statement, the
Prospectus and all other underwriting documents.

              (t)  The Company shall, as of the date hereof, have applied for
listing in Standard & Poor's Corporation Records Service (including annual
report information) or Moody's Industrial Manual (Moody's OTC Industrial Manual
not being sufficient for these purposes) and shall use its best efforts to have
the Company listed in such manual and shall maintain such listing for a period
of five (5) years following the Effective Date.

              (u)  For a period of three (5) years from the Effective Date, the
Company shall provide the Representative, on a 

                                       20
<PAGE>

not less than annual basis, with internal forecasts setting forth projected 
results of operations for each quarterly and annual period in the two (2) 
fiscal years following the respective dates of such forecasts.  Such 
forecasts shall be provided to the Representative more frequently than 
annually if prepared more frequently by management, and revised forecasts 
shall be prepared and provided to the Representative when required to reflect 
more current information, revised assumptions or actual results that differ 
materially from those set forth in the forecasts.

              (v)  For a period of three (3) years following the Effective
Date, the Company shall continue to retain Richard A. Eisner & Co. (or such
other nationally recognized accounting firm as is acceptable to the
Representative) as the Company's independent public accountants. 

              (w)  For a period of three (3) years following the Effective

to the announcement of quarterly financial information, the filing of the
Company's 10-Q (or 10-QSB) quarterly report (or other equivalent report) and the
mailing of quarterly financial information to shareholders.

              (x)  For a period of three (3) years from the Effective Date, the
Company will not offer or sell any of its securities pursuant to Regulation S of
the Act or at a discount from market or in a discounted transaction, without the
prior written consent of the Representative.

              (y) For a period of twenty-five (25) days following the Effective
Date, the Company will not issue press releases or engage in any other publicity
without the Representative's prior written consent, other than normal and
customary releases issued in the ordinary course of the Company's business or
those releases required by law.

              (z)  For a period of three (3) years from the Effective Date, the
Company will not increase or authorize an increase in the compensation of its
three (3) most highly paid employees, other than increases provided for in
employment agreements with the Company in effect as of the Effective Date and
disclosed in the Prospectus, without the prior written consent of the
Representative.

              (aa)   For a period of three (3) years following the Effective
Date, the Company will promptly submit to the Representative copies of
accountant's management reports and

similar correspondence between the Company's accountants and the Company.

              (ab) For a period of three (3) years following the Effective
Date, the Company will provide to the Representative ten day's written notice
prior to any issuance by the Company or its subsidiaries of any equity
securities or securities exchangeable for or convertible into equity securities
of the Company, except for (i) shares of Common Stock issuable upon exercise of
currently outstanding options and warrants or conversion of currently
outstanding convertible securities and (ii) options (and shares issuable upon
exercise of such options) available for future grant pursuant to any stock
option plan in effect on the Effective Date and the issuance of shares of 
Common Stock upon the exercise of such options.

              (ac)   For a period of three (3) years following the Effective
Date, the Company will retain a financial public relations firm reasonably
acceptable to the Representative. 

              (ad)   For a period of five (5) years following the Effective
Date the Company's Board of Directors shall be comprised of seven (7) persons,
at least three (3) of whom (including, if designated, the Representative's
director designee) must, during such period, be persons not otherwise affiliated
with the Company, its management or its founders.  In addition, during such
period, the Company will cause its Board of Directors to meet, either in person
or telephonically, a minimum of four (4) times per year and will hold a
shareholder's meeting at least once per annum.

              (ae)   Prior to the Effective Date, the Company shall have 
obtained directors' and officers' insurance naming the Representative as an 
additional insured party, in an amount equal to the lesser of (i) twenty-five 
percent (25%) of the gross proceeds of the offering and (ii) One Million 
Dollars ($1,000,000) and will maintain such insurance until at least three 
(3) years following the Closing Date.

              (af) The Company will employ the Representative or a designee 
of the Representative as a financial consultant on a non-exclusive basis for 
a period of two (2) years from the  Closing Date, pursuant to a separate 
written consulting agreement between the Company and the Representative 
and/or such designee (the "Consulting Agreement"), at an annual rate of 
Fifteen Thousand Dollars ($15,000) (exclusive of any accountable 
out-of-pocket expenses), the entire Thirty Thousand Dollars ($30,000) payable 
in full, in advance, on the Closing Date.  In addition, the Consulting

finder's fee in the event that the Company consummates a merger or 
acquisition directly or indirectly 

                                      22

<PAGE>

originated by the Representative during the term of the Consulting Agreement. 
 The Company further agrees to deliver a duly and validly executed copy of 
said Consulting Agreement, in form and substance acceptable to the 
Representative, on the Closing Date.

              (ag) For a period of five (5) years from the Effective Date, or 
until such earlier time as the Common Shares are listed on the New York Stock 
Exchange or the American Stock Exchange, the Company shall cause its legal 
counsel to provide the Representative with a list, to be updated at least 
annually, of those states in which the Offered Units, Shares and Warrants may 
be traded in non-issuer transactions under the Blue Sky laws of the 50 states.

         6.   Conditions of the Underwriters' Obligation to Purchase Shares 
from the Company.  The obligation of the several Underwriters to purchase and 
pay for the Offered Shares which they have agreed to purchase from the

order suspending the effectiveness of the Registration Statement will have 
been issued and no proceedings for that purpose will have been initiated or 
will be pending or, to the best of the Representative's or the Company's 
knowledge, will be contemplated by the Commission; and any request on the 
part of the Commission for additional information will have been complied 
with to the satisfaction of Underwriters' Counsel.

              (b)  At the time that this Agreement is executed and at the 
Closing Date, there will have been delivered to the Representative a signed

                     (ii)    The Company has full power and authority, 
corporate and other, to execute, deliver and perform this Agreement, the 
Consulting Agreement and the Representative's Warrant Agreement and to 
consummate the transactions contemplated hereby and thereby.  The execution, 
delivery and performance of this Agreement, the Consulting Agreement and the 
Representative's Warrant Agreement by the Company, the consummation by the 
Company of the transactions herein and therein contemplated and the 
compliance by the Company with the terms of this Agreement and the 
Representative's Warrant Agreement have been duly authorized by all necessary 
corporate action, and this Agreement has been duly executed and delivered by 
the Company.  This Agreement is (assuming for the purposes of this opinion 
that it is valid and binding upon the other party thereto), and each of the 
Consulting Agreement and the Representative's Warrant Agreement, when 
executed and delivered by the Company on the Closing Date, will be, valid and 
binding obligations of the Company, enforceable in accordance with their 
respective terms, subject, as to enforcement of remedies, to applicable 
bankruptcy, insolvency, reorganization, moratorium and other laws affecting 
the rights of creditors generally and the discretion of courts in granting 
equitable remedies and except that enforceability of the indemnification 
provisions set forth in Section 7 hereof and the contribution provisions set 
forth in 

                                      24

Section 8 hereof may be limited by the federal securities laws or public 
policy underlying such laws.

                    (iii)    The execution, delivery and performance of this 
Agreement, the Consulting Agreement and the Representative's Warrant 
Agreement by the Company, the consummation by the Company of the transactions 
herein and therein contemplated and the compliance by the Company with the 
terms of this Agreement, the Consulting Agreement and the Representative's 
Warrant Agreement do not, and will not, with or without the giving of notice 
or the lapse of time, or both, (A) result in a violation of the Certificate 
of Incorporation or By-Laws, each as amended, of the Company or the 
Subsidiary, (B) result in a breach of or conflict with any terms or 
provisions of, or constitute a default under, or result in the modification

security interest, charge or encumbrance upon any of the properties or assets 
of the Company or any the Subsidiary pursuant to, any indenture, mortgage, 
note, contract, commitment or other material agreement or instrument to which 
the Company or the Subsidiary is a party or by which the Company or the 
Subsidiary or any of the Company's or the Subsidiary's properties or assets 
are or may be bound or affected; (C) violate any existing applicable law, 
rule, regulation, judgment, order or decree of any governmental agency or 
court, domestic or foreign, having jurisdiction over the Company or the 
Subsidiary or any of the Company's or the Subsidiary's properties or 
business; or (D) have any effect on any Permit necessary for the Company or 
the Subsidiary to own or lease and operate its properties or conduct its 
business or on the ability of the Company to make use thereof.  

                     (iv)    To the best of Company Counsel's knowledge, no 
Permits of any court or governmental agency or body (other than under the 
Act, the Regulations and applicable state securities or Blue Sky laws) are 
required for the valid authorization, issuance, sale and delivery of the 
Shares or the Representative's Warrants, and the consummation by the Company 
of the transactions contemplated by this Agreement or the Representative's 
Warrant Agreement.

                      (v)    The Registration Statement has become effective 
under the Act; to the best of Company Counsel's knowledge, no stop order 
suspending the effectiveness of the Registration Statement has been issued, 
and no proceedings for that purpose have been instituted or are pending, 
threatened or contemplated under the Act or applicable state securities laws.

                     (vi)    The Registration Statement and the Prospectus, 
as of the Effective Date, and each amendment or supplement thereto as of its 
effective or issue date (except for the 

                                      25

<PAGE>

financial statements and other financial data included therein or omitted 
therefrom, as to which Company Counsel need not express an opinion) comply as 
to form in all material respects with the requirements of the Act and 
Regulations and the conditions for use of a registration statement on Form 
SB-2 have been satisfied by the Company. 

                    (vii)    The descriptions in the Registration Statement 
and the Prospectus of statutes, regulations, government classifications, 
contracts and other documents (including opinions of such counsel); and the 
response to Item 13 for Form SB-2 have been reviewed by Company Counsel, and, 
based upon such review, are accurate in all material respects and present 
fairly the information required to be disclosed, and there are no material 
statutes, regulations or government classifications, or, to the best of 
Company Counsel's knowledge, material contracts or documents, of a character 
required to be described in the Registration Statement or the Prospectus or 
to be filed as exhibits to the Registration Statement, which are not so 
described or filed as required.

                   None of the material provisions of the contracts or 
instruments described above violates any existing applicable law, rule, 
regulation, judgment, order or decree of any governmental agency or court 
having jurisdiction over the Company or the Subsidiary or any of their assets 
or businesses.  To the best of Company Counsel's knowledge, the Company is 
not in default under any contract or agreement material to its business or 
under any promissory note or other evidence of indebtedness for borrowed 
funds.

                   (viii)    The outstanding Common Shares and outstanding 
options and warrants to purchase Common Shares have been duly authorized and 
validly issued.  The outstanding Common Shares are fully paid and 
nonassessable. The outstanding options and warrants to purchase Common Shares 
constitute the valid and binding obligations of the Company, enforceable in 
accordance with their terms.  None of the outstanding Common Shares or 
options or warrants to purchase Common Shares has been issued in violation of 
the preemptive rights of any shareholder of the Company.  None of the holders 
of the outstanding Common Shares is subject to personal liability solely by 
reason of being such a holder. The offers and sales of the outstanding Common 
Shares and outstanding options and warrants to purchase Common Shares were at 
all relevant times either registered under the Act and the applicable state 
securities or Blue Sky laws or exempt from such registration requirements.  
The authorized Common Shares and outstanding options and warrants to purchase 
Common Shares conform to the descriptions thereof contained in the 
Registration Statement and Prospectus.  To the best of Company Counsel's 
knowledge, except as set forth in the 

                                      26

<PAGE>

Prospectus, no holders of any of the Company's securities has any rights, 
"demand", "piggyback" or otherwise, to have such securities registered under 
the Act.

                     (ix)    The issuance and sale of the Shares and the 
Warrant Shares have been duly authorized and, when the Shares and the Warrant 
Shares have been issued and duly delivered against payment therefor as 
contemplated by this Agreement and the Representative's Warrant Agreement, 
respectively, the Shares and the Warrant Shares will be validly issued, fully 
paid and nonassessable, and the holders thereof will not be subject to 
personal liability solely by reason of being such holders.  None of the 
Offered Units, the Shares nor the Warrant Shares are subject to preemptive 
rights of any shareholder of the Company.  The certificates representing the 
Shares are in proper legal form.

                      (x)    The issuance and sale of the Representative's 
Warrants have been duly authorized and, when paid for, issued and delivered 
pursuant to the terms of the Representative's Warrant Agreement, they will 
constitute the valid and binding obligations of the Company, enforceable as 
to the Company in accordance with their terms, to issue and sell the Warrant 
Shares.  The Representative's Warrants will not be subject to preemptive 
rights of any shareholder of the Company.  The Warrant Shares have been duly 
reserved for issuance upon exercise of the Representative's Warrants in 
accordance with the provisions of the Representative's Warrant Agreement.  
The Representative's Warrants conform to the descriptions thereof contained 
in the Registration Statement and the Prospectus.

                     (xi)    Upon delivery of the Offered Shares  to the 
Underwriters against payment therefor as provided in this Agreement, the 
Underwriters (assuming they are bona fide purchasers within the meaning of 
the Uniform Commercial Code) will acquire good title to the Offered Shares, 
free and clear of all liens, encumbrances, equities, security interests and 
claims.

                    (xii)    Assuming that the Representative exercises the 
over-allotment option to purchase any of the Optional Shares and make payment 
therefor in accordance with the terms of this Agreement, upon delivery of the 
Optional Shares so purchased to the Representative hereunder, the 
Representative (assuming it is a bona fide purchaser within the meaning of 
the Uniform Commercial Code) will acquire good title to such Optional Shares, 
free and clear of any liens, encumbrances, equities, security interests and 
claims.

                   (xiii)    To the best of Company Counsel's knowledge, 
there are no claims, actions, suits, proceedings, arbitrations, 
investigations or inquiries before any governmental 

                                      27

<PAGE>

agency, court or tribunal, foreign or domestic, or before any private 
arbitration tribunal, pending or threatened against the Company or the 
Subsidiary, or involving the Company's or the Subsidiary's properties or 
business, other than as described in the Prospectus, such description being 
accurate, and other than litigation incident to the kind of business 
conducted by the Company which, individually and in the aggregate, is not 
material.

                    (xiv)    Each of the Company and the Subsidiary owns or 
possesses adequate and enforceable rights to use all patents, patent 
applications, trademarks, service marks, copyrights, rights, trade secrets, 
confidential information, processes and formulations used or proposed to be 
used in the conduct of its business as described in the Prospectus 
(collectively the "Intangibles"); to the best of Company Counsel's knowledge, 
neither the Company nor the Subsidiary has infringed nor is infringing upon 
the rights of others with respect to the Intangibles; and, to the best of 
Company Counsel's knowledge, neither the Company nor the Subsidiary has 
received any notice that it has or may have infringed, is infringing upon or 
is conflicting with the asserted rights of others with respect to the 
Intangibles which might, singly or in the aggregate, materially adversely 
affect its business, results of operations or financial condition and such 
counsel is not aware of any licenses with respect to the Intangibles which 
are required to be obtained by the Company or the Subsidiary.  

              Company Counsel has participated in reviews and discussions in 
connection with the preparation of the Registration Statement and the 
Prospectus, and in the course of such reviews and discussions and such other 
investigation as Company Counsel deemed necessary, no facts came to its 
attention which lead it to believe that (A) the Registration Statement 
(except as to the financial statements and other financial data contained 
therein, as to which Company Counsel need not express an opinion), on the 
Effective Date, contained any untrue statement of a material fact required to 
be stated therein or omitted to state any material fact required to be stated 
therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading, or that (B) the 
Prospectus contains any untrue statement of a material fact or omits to state 
any material fact necessary in order to make the statements therein, in the 
light of the circumstances under which they were made, not misleading.  

              In rendering its opinion pursuant to this Section 6(b), Company 
Counsel may rely upon the certificates of government officials and officers 
of the Company as to matters of fact, provided that Company Counsel shall 
state that they have no reason to believe, and do not believe, that they are 
not justified in relying upon such certificates of government officials and 
officers of the Company as to matters of fact, as the case may be.


                                      28

              The opinion letters delivered pursuant to this Section 6(b) 
shall state that any opinion given therein qualified by the phrase "to the 
best of our knowledge" is being given by Company Counsel after due 
investigation of the matters therein discussed.

              (c)  At the time this Agreement is executed, and at the Closing 
Date there will have been delivered to the Representative a signed opinion of 
__________________, special regulatory counsel for the Company ("Special 
Counsel") dated as of the date hereof on the Closing Date, as the case may 
be, reasonably satisfactory to Underwriters' Counsel, to the effect that:

                   (i)  Each of the Company and the Subsidiary is in 
compliance, in all material respects, with the provisions of all laws 
relating to the regulation of the Company's products, including the Federal 
Food, Drug and Cosmetic Act (the "FD&C Act") and all state laws comparable to 
the FD&C Act, the rules, regulations promulgated thereunder and all rules and 
regulations promulgated by the Food and Drug Administration ("FDA") and all 
Comparable state regulatory authorities;

                   (ii)  Each of the Company and the Subsidiary has all 
authorizations, approvals, consents, orders, registrations, licenses or 
permits of any Court or the FDA and all state regulatory authorities 
comparable to the FDA which are necessary or required for the Company to 
conduct its current business in material compliance with the FD&C Act or 
Comparable state law;

                   (iii)  Neither the Company nor the Subsidiary has any 
material liabilities, debts, obligations or claims asserted against it, 
whether accrued, absolute, contingent or otherwise, and whether due or to 
become due, on account of such regulatory matters;

                   (iv)  The Company and the Subsidiary do not manufacture, 
fabricate, assemble or receive any products or component parts in violation 
of the FD&C Act or any comparable state law, or any rule or regulation 
promulgated thereunder, or contract for the manufacture, fabrication, 
assembly or delivery of any products or component parts in violation of the 
FD&C Act or any comparable state law, or any rule or regulation promulgated 
thereunder;

                   (v)  None of the material provisions of the contracts or 
instruments, as described in the Registration Statement, violates any 
existing applicable law, rule, regulation, judgment, order or decree of any 
governmental agency or court having jurisdiction over the Company or any of 
its assets or business relating to or promulgated by the FDA or any 
comparable state regulatory authorities.

                   (vi)  The discussion contained in the Registration 
Statement with respect to the FDA and comparable state regulatory authorities 
and of the laws relating to the regulation of the Company's products, 
including the FD&C Act and comparable state laws, rules and regulations, is 
accurate, complete and true in all material respects and does not omit to 
state any material fact required to be stated therein or necessary to make 
the statements therein in light of the circumstances under which they were 
made, not misleading.

              Special Counsel has participated in reviews and discussions in 
connection with the preparation of the Registration Statement and the 
Prospectus, and in the course of such reviews and discussions and such other 
investigation as Special Counsel deemed necessary, no facts came to its 
attention which lead it to believe that the sections of the Registration 
Statement entitled "Risk Factors - Government Regulation; No Assurance of 
Regulatory Approvals" and "Business," on the Effective Date, contained any 
untrue statement of a material fact required to be stated therein or omitted 
to state any material fact required to be stated therein or necessary to make 
the statements therein, in light of the circumstances under which they were 
made, not misleading.

              (d)  At the Closing Date, there will have been delivered to the 
Representative a signed opinion of Underwriters' Counsel, dated as of the 
Closing Date, to the effect that the opinions delivered pursuant to Sections 
6(b) and (c) hereof appear on their face to be appropriately responsive to 
the requirements of this Agreement, except to the extent waived by the 
Representative, specifying the same, and with respect to such other related 
matters as the Representative may require.

              (e)  At the Closing Date (i) the Registration Statement and the 
Prospectus and any amendments or supplements thereto will contain all 
material statements which are required to be stated therein in accordance 
with the Act and the Regulations and will conform in all material respects to 
the requirements of the Act and the Regulations, and neither the Registration 
Statement nor the Prospectus nor any amendment or supplement thereto will 
contain any untrue statement of a material fact or omit to state any material 
fact required to be stated therein or necessary to make the statements 
therein, in light of the circumstances under which they were made, not 
misleading; (ii) since the respective dates as of which information is given 
in the Registration Statement and the Prospectus, there will not have been 
any material adverse change in the financial condition, results of operations 
or general affairs of the Company from that set forth or contemplated in the 
Registration Statement and the Prospectus, except changes which the 
Registration Statement and the Prospectus indicate might occur after the 
Effective Date; (iii) since the respective dates as of which information is 
given in the Registration Statement and the Prospectus, there shall have been 
no material transaction, contract or agreement entered into by the Company, 
other than in the 

                                      30

<PAGE>

ordinary course of business, which would be required to be set forth in the 
Registration Statement and the Prospectus, other than as set forth therein; 
and (iv) no action, suit or proceeding at law or in equity will be pending 
or, to the best of the Company's knowledge, threatened against the Company 
which is required to be set forth in the Registration Statement and the 
Prospectus, other than as set forth therein, and no proceedings will be 
pending or, to the best of the Company's knowledge, threatened against the 
Company before or by any federal, state or other commission, board or 
administrative agency wherein an unfavorable decision, ruling or finding 
would materially adversely affect the business, property, financial condition 
or results of operations of the Company, other than as set forth in  the 
Registration Statement and the Prospectus.  At the Closing Date, there will 
be delivered to the Representative a certificate signed by the Chairman of 
the Board or the President or a Vice President of the Company, dated the 
Closing Date, evidencing compliance with the provisions of this Section 6(e) 
and stating that the representations and warranties of the Company set forth 
in Section 4 hereof were accurate and complete in all material respects when 
made on the date hereof and are accurate and complete in all material 
respects on the Closing Date as if then made; that the Company has performed 
all covenants and complied with all conditions required by this Agreement to 
be performed or complied with by the Company prior to or as of the Closing 
Date; and that, as of the Closing Date, no stop order suspending the 
effectiveness of the Registration Statement has been issued and no 
proceedings for that purpose have been initiated or, to the best of his 
knowledge, are contemplated or threatened.  In addition, the Representative 
will have received such other and further certificates of officers of the 
Company as the Representative or Underwriters' Counsel may reasonably request.

              (f)  At the time that this Agreement is executed and at the 
Closing Date, the Representative will have received a signed letter from 
Richard A. Eisner & Co., dated the date such letter is to be received by the 
Representative and addressed to it, confirming that it is a firm of 
independent public accountants within the meaning of the Act and Regulations 
and stating that: (i) insofar as reported on by it, in its opinion, the 
financial statements of the Company included in the Prospectus comply as to 
form in all material respects with the applicable accounting requirements of 
the Act and the applicable Regulations; (ii) on the basis of procedures and 
inquiries (not constituting an examination in accordance with generally 
accepted auditing standards) consisting of a reading of the unaudited interim 
financial statements of the Company, if any, appearing in the Registration 
Statement and the Prospectus and the latest available unaudited interim 
financial statements of the Company, if more recent than that appearing in 
the Registration Statement and Prospectus, inquiries of officers of the 
Company responsible for financial and accounting matters as to the 
transactions and events subsequent to the date of the latest audited 
financial statements of the Company, and a reading of the minutes of meetings 
of the shareholders, the 

                                      31

<PAGE>

Board of Directors of the Company and any committees of the Board of 
Directors, as set forth in the minute books of the Company, nothing has come 
to its attention which, in its judgment, would indicate that (A) during the 
period from the date of the latest financial statements of the Company 
appearing in the Registration Statement and Prospectus to a specified date 
not more than three business days prior to the date of such letter, there 
have been any decreases in net current assets or net assets as compared with 
amounts shown in such financial statements or decreases in net sales or 
decreases in total or per share net income compared with the corresponding 
period in the preceding year or any change in the capitalization or long-term 
debt of the Company, except in all cases as set forth in or contemplated by 
the Registration Statement and the Prospectus, and (B) the unaudited interim 
financial statements of the Company, if any, appearing in the Registration 
Statement and the Prospectus, do not comply as to form in all material 
respects with the applicable accounting requirements of the Act and the 
Regulations or are not fairly presented in conformity with generally accepted 
accounting principles and practices on a basis substantially consistent with 
the audited financial statements included in the Registration Statement or 
the Prospectus; and (iii) it has compared specific dollar amounts, numbers of 
shares, numerical data, percentages of revenues and earnings, and other 
financial information pertaining to the Company set forth in the Prospectus 
(with respect to all dollar amounts, numbers of shares, percentages and other 
financial information contained in the Prospectus, to the extent that such 
amounts, numbers, percentages and information may be derived from the general 
accounting records of the Company, and excluding any questions requiring an 
interpretation by legal counsel) with the results obtained from the 
application of specified readings, inquiries and other appropriate procedures 
(which procedures do not constitute an examination in accordance with 
generally accepted auditing standards) set forth in the letter, and found 
them to be in agreement.

              (g)  There shall have been duly tendered to the Representative 
certificates representing the Offered Shares to be sold on the Closing Date.

              (h)  The NASD shall have indicated that it has no objection to 
the underwriting arrangements pertaining to the sale of the Offered Shares by 
the Underwriters or the sale of the Shares by the Representative.

              (i)  No action shall have been taken by the Commission or the 
NASD the effect of which would make it improper, at any time prior to the 
Closing Date or the Option Closing Date, as the case may be, for any member 
firm of the NASD to execute transactions (as principal or as agent) in the 
Shares, and no proceedings for the purpose of taking such action shall have 
been instituted or shall be pending, or, to the best of the Representative's 
or the Company's knowledge, shall be contemplated  


                                      32

<PAGE>

by the Commission or the NASD.  The Company represents at the date hereof, 
and shall represent as of the Closing Date or Option Closing Date, as the 
case may be, that it has no knowledge that any such action is in fact 
contemplatedby the Commission or the NASD.

              (j)  The Company meets the current and any existing and proposed
criteria for inclusion of the Offered Shares in NASDAQ.

              (k)  All proceedings taken at or prior to the Closing Date or 
the Option Closing Date, as the case may be, in connection with the 
authorization, issuance and sale of the Shares shall be reasonably 
satisfactory in form and substance to the Representative and to Underwriters' 
Counsel, and such counsel shall have been furnished with all such documents, 
certificates and opinions as they may request for the purpose of enabling 
them to pass upon the matters referred to in Section 6(d) hereof and in order 
to evidence the accuracy and completeness of any of the representations, 
warranties or statements of the Company, the performance of any covenants of 
the Company, or the compliance by the Company with any of the conditions 
herein contained.

              (l)  As of the date hereof, the Company will have delivered to 
the Underwriters the written undertakings of its officers, directors and 
security holders and/or registration rights holders, as the case may be, to 
the effect of the matters set forth in Sections 5(l) and (q).

              If any of the conditions specified in this Section 6 have not 
been fulfilled, this Agreement may be terminated by the Representative on 
notice to the Company.

         7.   Indemnification.

              (a)  The Company agrees to indemnify and hold harmless each 
Underwriter, including specifically each person that may be substituted for 
an Underwriter as provided in Section 10 hereof, each officer, director, 
partner, employee and agent of any Underwriter, and each person, if any, who 
controls any of the Underwriters within the meaning of Section 15 of the Act 
or Section 20(a) of the Exchange Act, from and against any and all losses, 
claims, damages, expenses or liabilities, joint or several (and actions in 
respect thereof), to which they or any of them may become subject under the 
Act or under any other statute or at common law or otherwise, and, except as 
hereinafter provided, will reimburse each of the Underwriters and each such 
person, if any, for any legal or other expenses reasonably incurred by them 
or any of them in connection with investigating or defending any actions, 
whether or not resulting in any liability, insofar as such losses, claims, 
damages, expenses, liabilities or actions arise out of or are based upon any 
untrue statement or alleged untrue statement of a material fact contained (i) 
in the Registration Statement, in any Preliminary Prospectus or in the 
Prospectus (or the Registration 


                                      33

<PAGE>


Statement or Prospectus as from time to time amended or supplemented) or (ii) 
in any application or other document executed by the Company, or based upon 
written information furnished by or on behalf of the Company, filed in any 
jurisdiction in order to qualify the Shares under the securities laws thereof 
(hereinafter "application"), or arise out of or are based upon the omission 
or alleged omission to state therein a material fact required to be stated 
therein or necessary in order to make the statements therein not misleading, 
in light of the circumstances under which they were made, unless such untrue 
statement or omission was made in such Registration Statement, Preliminary 
Prospectus, Prospectus or application in reliance upon and in conformity with 
information furnished in writing to the Company in connection therewith by an 
Underwriter or any such person through an Underwriter expressly for use 
therein; provided, however, that the indemnity agreement contained in this 
Section 7(a) with respect to any Preliminary Prospectus will not inure to the 
benefit of an Underwriter (or to the benefit of any other person that may be 
indemnified pursuant to this Section 7(a)) if (A) the person asserting any 
such losses, claims, damages, expenses or liabilities purchased the Shares 
which are the subject thereof from such Underwriter or other indemnified 
person; (B) such Underwriter or other indemnified person failed to send or 
give a copy of the Prospectus to such person at or prior to the written 
confirmation of the sale of such Shares to such person; and (C) the 
Prospectus did not contain any untrue statement or alleged untrue statement 
or omission or alleged omission giving rise to such cause, claim, damage, 
expense or liability.

              (b)  Each Underwriter (including specifically each person that 
may be substituted for an Underwriter as provided in Section 10 hereof) 
agrees to indemnify and hold harmless the Company, each of its directors, 
each of its officers who have signed the Registration Statement and each 
person, if any, who controls the Company within the meaning of Section 15 of 
the Act or Section 20(a) of the Exchange Act, from and against any and all 
losses, claims, damages, expenses or liabilities, joint or several (and 
actions in respect thereof), to which they or any of them may become subject 
under the Act or under any other statute or at common law or otherwise, and, 
except as hereinafter provided, will reimburse the Company and each such 
director, officer or controlling person for any legal or other expenses 
reasonably incurred by them or any of them in connection with investigating 
or defending any actions, whether or not resulting in any liability, insofar 
as such losses, claims, damages, expenses, liabilities or actions arise out 
of or are based upon any untrue statement or alleged untrue statement of a 
material fact contained (i) in the Registration Statement, in any Preliminary 
Prospectus or in the Prospectus (or the Registration Statement or Prospectus 
as from time to time amended or supplemented) or (ii) in any application 
(including any application for registration of the Shares under state 
securities or Blue Sky laws), or arise out of or are based upon the omission 
or alleged omission to state therein a material fact required to be stated 
therein or necessary in order to make 


                                      34

<PAGE>

the statements therein not misleading, in light of the circumstances under 
which they were made, but only insofar as any such statement or omission was 
made in reliance upon and in conformity with information furnished in writing 
to the Company in connection therewith by such Underwriter, or by the 
Representative on behalf of such Underwriter, expressly for use therein.

              (c)  Promptly after receipt of notice of the commencement of 
any action in respect of which indemnity may be sought against any 
indemnifying party under this Section 7, the indemnified party will notify 
the indemnifying party in writing of the commencement thereof, and the 
indemnifying party will, subject to the provisions hereinafter stated, assume 
the defense of such action (including the employment of counsel satisfactory 
to the indemnified party and the payment of expenses) insofar as such action 
relates to an alleged liability in respect of which indemnity may be sought 
against the indemnifying party. After notice from the indemnifying party of 
its election to assume the defense of such claim or action, the indemnifying 
party shall no longer be liable to the indemnified party under this Section 7 
for any legal or other expenses subsequently incurred by the indemnified 
party in connection with the defense thereof other than reasonable costs of 
investigation; provided, however, that if, in the reasonable judgment of the 
indemnified party or parties, it is advisable for the indemnified party or 
parties to be represented by separate counsel, the indemnified party or 
parties shall have the right to employ a single counsel to represent the 
indemnified parties who may be subject to liability arising out of any claim 
in respect of which indemnity may be sought by the indemnified parties 
thereof against the indemnifying party, in which event the fees and expenses 
of such separate counsel shall be borne by the indemnifying party.  Any party 
against whom indemnification may be sought under this Section 7 shall not be 
liable to indemnify any person that might otherwise be indemnified pursuant 
hereto for any settlement of any action effected without such indemnifying 
party's consent which consent shall not be unreasonably withheld.

         8.   Contribution.  To provide for just and equitable contribution, 
if (i) an indemnified party makes a claim for indemnification pursuant to 
Section 7 hereof (subject to the limitations thereof) and it is finally 
determined, by a judgment, order or decree not subject to further appeal, 
that such claim for indemnification may not be enforced, even though this 
Agreement expressly provides for indemnification in such case; or (ii) any 
indemnified or indemnifying party seeks contribution under the Act, the 
Exchange Act, or otherwise, then the Company (including, for this purpose, 
any contribution made by or on behalf of any director of the Company, any 
officer of the Company who signed the Registration Statement and any 
controlling person of the Company) as one entity and the Underwriters 
(including, for this purpose, any contribution by or on behalf of each 
person, if any, who controls any Underwriter within the meaning of Section 15 
of the Act or Section 20(a) of the Exchange Act and each officer, 

                                      35

<PAGE>

director, partner, employee and agent of any of the Underwriters) as a second 
entity, shall contribute to the losses, liabilities, claims, damages and 
expenses whatsoever to which any of them may be subject, so that the 
Underwriters are responsible for the proportion thereof equal to the 
percentage which the underwriting discount per Share set forth on the cover 
page of the Prospectus represents of the initial public offering price per 
Share set forth on the cover page of the Prospectus and the Company is 
responsible for the remaining portion; provided, however, that if applicable 
law does not permit such allocation, then, if applicable law permits, other 
relevant equitable considerations such as the relative fault of the Company 
and the Underwriters in connection with the facts which resulted in such 
losses, liabilities, claims, damages and expenses shall also be considered.  
The relative fault, in the case of an untrue statement, alleged untrue 
statement, omission or alleged omission, shall be determined by, among other 
things, whether such statement, alleged statement, omission or alleged 
omission relates to information supplied by the Company or by the 
Underwriters, and the parties' relative intent, knowledge, access to 
information and opportunity to correct or prevent such statement, alleged 
statement, omission or alleged omission.  The Company, on one hand, and the 
Underwriters, on the other hand,  agree that it would be unjust and 
inequitable if the respective obligations of the Company and the Underwriters 
for contribution were determined by pro rata or per capita allocation of the 
aggregate losses, liabilities, claims, damages and expenses or by any other 
method of allocation that does not reflect the equitable considerations 
referred to in this Section 8.  No person guilty of a fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Act) will be 
entitled to contribution from any person who is not guilty of such fraudulent 
misrepresentation.  For purposes of this Section 8, each person, if any, who 
controls any of the Underwriters within the meaning of Section 15 of the Act 
or Section 20(a) of the Exchange Act and each officer, director, partner, 
employee and agent of any of the Underwriters will have the same rights to 
contribution as the Underwriters, and each person, if any, who controls the 
Company within the meaning of Section 15 of the Act or Section 20(a) of the 
Exchange Act, each officer of the Company who has signed the Registration 
Statement and each director of the Company will have the same rights to 
contribution as the Company, subject in each case to the provisions of this 
Section 8.  Anything in this Section 8 to the contrary notwithstanding, no 
party will be liable for contribution with respect to the settlement of any 
claim or action effected without its written consent.  This Section 8 is 
intended to supersede, to the extent permitted by law, any right to 
contribution under the Act or the Exchange Act or otherwise available.

         9.   Survival of Indemnities, Contribution, Warranties and 
Representations.  The respective indemnity and contribution agreements of the 
Company and the Underwriters contained in Sections 7 and 8 hereof, and the 
representations and warranties of the Company contained in this Agreement 
shall remain operative and 


                                      36

<PAGE>

in full force and effect, regardless of any termination or cancellation of 
this Agreement or any investigation made by or on behalf of the Underwriters, 
the Company or any of its directors and officers or any controlling person 
referred to in said Sections, and shall survive the delivery of, and payment 
for, the Shares.

         10.  Substitution of Underwriters.

              (a)  If one or more Underwriters should default in its or their 
obligation to purchase and pay for any Offered Shares hereunder and if the 
aggregate number of such Offered Shares which all Underwriters so defaulting 
have agreed to purchase does not exceed 10% of the total number of the 
Offered Shares, the non-defaulting Underwriters will be obligated severally 
to purchase and pay for (in addition to the number of Offered Shares set 
forth opposite their names in Schedule A attached hereto) the full number of 
Offered Shares agreed to be purchased by all defaulting Underwriters, and not 
so purchased, in proportion to their respective commitments hereunder.  In 
such event the Representative, for the accounts of the several nondefaulting 
Underwriters, may take up and pay for all or any part of such additional 
Offered Shares to be purchased by each such Underwriter under this Section 
10(a), and may postpone the Closing Date to a time not exceeding three full 
business days after the Closing Date determined as provided in Section 2 
hereof.

              (b)  If one or more Underwriters should default in its or their 
obligation to purchase and pay for any Offered Shares hereunder and if the 
aggregate number of such Offered Shares which all Underwriters so defaulting 
have agreed to purchase exceeds 10% of the total number of Offered Shares, or 
if one or more Underwriters for any reason permitted hereunder should cancel 
its or their obligation to purchase and pay for Offered Shares hereunder, the 
non-cancelling and non-defaulting Underwriters (hereinafter called the 
"remaining Underwriters") will have the right to purchase such Offered Shares 
in such proportion as may be agreed among them at the Closing Date determined 
as provided in Section 2 hereof.  If the remaining Underwriters do not 
purchase and pay for such Offered Shares at such Closing Date, the Closing 
Date will be postponed for 24 hours and the remaining Underwriters will have 
the right to purchase such Offered Shares, or to substitute another person or 
persons to purchase the same, or both, at such postponed Closing Date.  If 
purchasers have not been found for such Offered Shares by such postponed 
Closing Date, the Closing Date will be postponed for a further 24 hours, and 
the Company will have the right to substitute another person or persons, 
reasonably satisfactory to the Representative to purchase such Offered Shares 
at such second postponed Closing Date.  If it shall be arranged for the 
remaining Underwriters or substituted underwriters to take up the Offered 
Shares of the defaulting Underwriter or Underwriters as provided in this 
Section, the Company shall have the right to postpone the time of delivery 
for a period of not more than three (3) full business days, in order to 
effect whatever changes may 

                                      37

<PAGE>

thereby be made necessary in the Registration Statement or the Prospectus or 
in any other documents or arrangements, and the Company agrees promptly to 
file any amendments to the Registration Statement or supplements to the 
Prospectus which may thereby be made necessary. If the Company has not found 
such purchasers for such Offered Shares by such second postponed Closing 
Date, then this Agreement will automatically terminate, and neither the 
Company nor the remaining Underwriters will be under any obligation under 
this Agreement (except that the Company and the Underwriters will remain 
liable to the extent provided in Sections 7 and 8 hereof and the Company will 
also remain liable to the extent provided in Section 5(j) hereof).  As used 
in this Agreement, the term "Underwriter" includes any person substituted for 
an Underwriter under this Section 10(b). Nothing in Section 11 hereof will 
relieve a defaulting Underwriter from the liability for its default and 
nothing in this Section 10(b) will obligate any Underwriter to purchase or 
find purchasers for any Offered Shares in excess of those agreed to be 
purchased by such Underwriter under the terms of Section 2 hereof.

         11.  Termination of Agreement.

              (a)  The Company, by written or telegraphic notice to the 
Representative, or the Representative, by written or telegraphic notice to 
the Company, may terminate this Agreement prior to the earlier of (i) 10:00 
A.M., New York City time, on the first full business day after the Effective 
Date; or (ii) the time when the Underwriters, after the Registration 
Statement becomes effective, release the Offered Shares for public offering.  
The time when the Underwriters "release the Offered Shares for public 
offering" for the purposes of this Section 11 means the time when the 
Underwriters release for publication the first newspaper advertisement, which 
is subsequently published, relating to the Offered Shares, or the time when 
the Underwriters release for delivery to members of a selling group copies of 
the Prospectus and an offering letter or an offering telegram relating to the 
Offered Shares, whichever will first occur.

              (b)  This Agreement, including without limitation, the 
obligation to purchase the Shares and the obligation to purchase the Optional 
Shares after exercise of the option referred to in Section 3 hereof, are 
subject to termination in the absolute discretion of the Underwriters, by 
notice given to the Company prior to delivery of and payment for all the 
Offered Shares or the Optional Shares, as the case may be, if, prior to such 
time, any of the following shall have occurred: (i) the Company withdraws the 
Registration Statement from the Commission or the Company does not or cannot 
expeditiously proceed with the public offering; (ii) the representations and 
warranties in Section 4 hereof are not materially correct or cannot be 
complied with; (iii) trading in securities generally on the New York Stock 
Exchange or AMEX will have been suspended; (iv) limited or minimum prices 
will have been established on either such Exchange; (v) a banking moratorium 
will 

                                      38

<PAGE>

have been declared either by federal or New York State authorities; (vi) any 
other restrictions on transactions in securities materially affecting the 
free market for securities or the payment for such securities, including the 
Offered Shares or the Optional Shares, will be established by either of such 
Exchanges, by the Commission, by any other federal or state agency, by action 
of the Congress or by Executive Order; (vii) trading in any securities of the 
Company shall have been suspended or halted by any national securities 
exchange, the NASD or the Commission; (viii) there has been a materially 
adverse change in the condition (financial or otherwise), prospects or 
obligations of the Company; (ix) the Company will have sustained a material 
loss, whether or not insured, by reason of fire, flood, accident or other 
calamity; (x) any action has been taken by the government of the United 
States or any department or agency thereof which, in the judgment of the 
Representative, has had a material adverse effect upon the market or 
potential market for securities in general; or (xi) the market for securities 
in general or political, financial or economic conditions will have so 
materially adversely changed that, in the judgment of the Representative, it 
will be impracticable to offer for sale, or to enforce contracts made by the 
Underwriters for the resale of, the Offered Shares or the Optional Shares, as 
the case may be.

              (c)  If this Agreement is terminated pursuant to Section 6 
hereof or this Section 11 or if the purchases provided for herein are not 
consummated because any condition of the Underwriters' obligations hereunder 
is not satisfied or because of any refusal, inability or failure on the part 
of the Company to comply with any of the terms or to fulfill any of the 
conditions of this Agreement, or if for any reason the Company shall be 
unable to or does not perform all of its obligations under this Agreement, 
the Company will not be liable to any of the Underwriters for damages on 
account of loss of anticipated profits arising out of the transactions 
covered by this Agreement, but the Company will remain liable to the extent 
provided in Sections 5(j), 7, 8 and 9 of this Agreement.

         12.  Information Furnished by the Underwriters to the Company.  It 
is hereby acknowledged and agreed by the parties hereto that for the purposes 
of this Agreement, including, without limitation, Sections 4(f), 7(a), 7(b)

           [As filed with the Secretary of State of Delaware on 1/11/93]

                                                                 Exhibit 3.1

                             CERTIFICATE OF INCORPORATION

                                          OF

                                    BIO-VED, INC.


FIRST:   The name of the corporation is BIO-VED, INC.

SECOND:  The address of the Corporation's registered office in the State of
Delaware is 15 East North Street, City of Dover, County of Kent.  The name of
its registered agent at such address is United Corporate Services, Inc.

THIRD:   The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the Delaware General
Corporation Law.

FOURTH:
         I.   The aggregate number of shares which the Corporation shall have 
authority to issue is Three Hundred (300) shares, consisting of (i) One 
Hundred (100) shares of Class A Common Stock, par value $.001 per share 
("Class A Common Stock"), (ii) One Hundred (100) shares of Class B Common 
Stock, par value $.001 per share ("Class B Common Stock"), and (iii) One 
Hundred (100) shares of Preferred Stock, par value $.01 per share ("Preferred 
Stock").

         II.  Except as otherwise provided in this Article FOURTH, the rights,
preferences and limitations of Class A Common Stock and Class B Common Stock
shall be identical in all respects:

              (a)  The dividend rights of the holders of shares of Class A
Common Stock and Class B Common Stock shall be identical, except that no 
stock dividends on the Class A Common Stock may be paid in Class B Common 
Stock and no stock dividends on the Class B Common Stock may be paid in Class 
A Common Stock. Whenever a stock dividend is paid, the holder of a share of 
any class of common stock shall be paid the same number of shares of common 
stock of the class of such share as are paid to the holder of a share of 
common stock of any other class in shares of common stock of such other 
class. Whenever a combination or subdivision of the shares of any class is 
made, the same combination or subdivision shall be made with respect to other 
classes.

              (b)  Each holder of Class A Common Stock shall have one vote in
respect of each share of Class A Common Stock held by him and each holder of
Class B Common Stock shall have four votes in respect of each share of Class B
Common Stock held by him on all matters voted upon by the shareholders.

              (c)  (i)  All outstanding shares of Class B Common Stock shall be
convertible at all times, at the election of the holder thereof, into an equal
number of fully paid 



<PAGE>

and nonassessable shares of Class A Common Stock by delivery of written notice
by the holder of such shares of Class B Common Stock to the Corporation or its
transfer agent of his election together with the certificate(s) representing the
shares to be converted. Thereupon, the Corporation or its transfer agent, as the
case may be, shall exchange such certificate(s) for a certificate or
certificates representing an equal number of shares of Class A Common Stock. 
Shares of Class B Common Stock shall be deemed to have been converted
immediately prior to the close of business the day upon which the Corporation 
or its transfer agent receives such shares for conversion.  The person 
entitled to receive the Class A Common Stock issuable upon such conversion 
shall be treated for all purposes as the record holder of such Class A Common 
Stock at such time. Thereafter, the shares of Class B Common Stock so 
converted shall be authorized and unissued shares of Class B Common Stock of 
the Corporation.     

                   (ii) Except as provided in subparagraph (iii) below, upon
the sale, assignment, transfer, conveyance, or other disposition, whether
voluntary, by operation of law or otherwise (a "Transfer," which, for the
purpose hereof, shall not include a pledge) of shares of Class B Common Stock,
other than a transfer to another holder of Class B Common Stock or to a private
charitable foundation as to which a holder of Class B Common Stock is the sole
voting member, the shares so transferred shall, by virtue of such Transfer,
automatically be converted into an equal number of fully paid and nonassessable
shares of Class A Common Stock.  Thereafter, the shares of Class B Common Stock
so converted shall be authorized and unissued shares of Class B Common Stock of
the Corporation.

                  (iii) Upon the death of any holder of Class B Common Stock,
the shares of Class B Common Stock so held as of the date of death of the
deceased shareholder shall be automatically converted into an equal number of
fully paid and nonassessable shares of Class A Common Stock unless and to the
extent that any of such shares are purchased by another holder of Class B Common
Stock on or prior to 90 days from the date that a legal representative is duly
appointed by a court of competent jurisdiction or 120 days from such date if
within such 90 day period another holder of Class B Common Stock has exercised
any right to purchase shares of Class B Common Stock held by such legal
representative.  If there should be only one holder of Class B Common Stock,
effective immediately upon his death, the shares of Class B Common Stock so held
as of the date of death shall be automatically converted into an equal number of
fully paid and nonassessable shares of Class A Common Stock.  Thereafter, the
shares of Class B Common Stock so converted shall be authorized and unissued
shares of Class B Common Stock of the Corporation.

                   (iv) With respect to any shares of Class B Common Stock
converted into Class A Common Stock pursuant to paragraphs (i) and (iii) above,
until surrender as hereinafter 

                                         -2-
<PAGE>

provided, each outstanding certificate, which prior to such conversion
represented shares of Class B Common Stock, shall be deemed for all purposes to
evidence ownership of the number of shares of Class A Common Stock into which
the shares of Class B Common Stock shall have been converted.  Upon surrender to
the Corporation, or its transfer agent, for cancellation of the certificate or
certificates representing such shares, the holder thereof shall be entitled to
receive a certificate or certificates representing the number of shares of
common stock to which such holder is entitled.

         III. The Board of Directors of the Corporation is authorized, subject
to limitations prescribed by law and the provisions of this Article FOURTH, to
provide for, from time to time, in one or more series of any number, the
issuance of shares of Preferred Stock, and, by filing a certificate pursuant to
the General Corporation Law of the State of Delaware, to establish the number of
shares to be included in each such series and to fix the designation, relative
rights, preferences, qualifications and limitations of the shares of each such
series.  The authority of the Board of Directors with respect to each series
shall include, but not be limited to, determination of each of the following:

              (a)  The number of shares constituting that series and the
distinctive designation of that series;

              (b)  The dividend rate on the shares of the series, whether
dividends shall be cumulative and, if so, from which date or dates, and whether
they shall be payable in preference to, or in another relation to, the dividends
payable on any other class or classes or series of stock;

              (c)  Whether that series shall have voting rights, in addition to
the voting rights provided by law, and, if so, the terms of such voting rights;

              (d)  Whether that series shall have conversion or exchange
privileges, and, if so, the terms and conditions of such conversion or exchange,
including provision for adjustment of the conversion or exchange rate in such
events as the Board of Directors shall determine;

              (e)  Whether or not the shares of that series shall be
redeemable, and, if so, the terms and conditions of such redemption, including
the manner of selecting shares for redemption if less than all such shares are
to be redeemed, the date or dates upon or after which they shall be redeemable,
and the amount per share payable in case of redemption, which amount may vary
under different conditions and at different redemption dates;

              (f)  Whether that series shall be entitled to the benefit of a
sinking fund to be applied to the purchase or 

                                         -3-
<PAGE>

redemption of shares of that series and, if so, the terms and amounts of such
sinking fund;

              (g)  The right of the shares of the series to the benefit of
conditions and restrictions upon the creation of indebtedness of the Corporation
or any subsidiary upon the issue of any additional stock (including additional
shares of such series or of any other series) and upon the payment of dividends
or the making of other distributions on and the purchase, redemption or other
acquisition by the Corporation or any subsidiary of, any outstanding stock of
the Corporation;

              (h)  The right of the shares of that series in the event of any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation and whether such rights shall be in preference to or in another
relation to the comparable rights of any other class or classes or series of
stock; and

              (i)  Any other relative, participating optional or other special,
rights, qualifications, limitations or restrictions of that series.

         IV.  Shares of any series of Preferred Stock which have
been redeemed (whether through the operation of a sinking fund or otherwise) or
which, if convertible or exchangeable, have been converted into or exchanged for
shares of stock of any other class or classes, shall have the status of
authorized and unissued shares of Preferred Stock of the same series and may be
reissued as a part of the series of which they were originally a part or may be
reclassified and reissued as part of any other series of Preferred Stock or of a
new series of Preferred Stock to be created by resolution or resolutions of the
Board of Directors, all subject to the conditions and restrictions on issuance
set forth in the resolution or resolutions adopted by the Board of Directors
providing for the issue of any series of Preferred Stock.

         V.   Except as otherwise provided by the resolution or resolutions
providing for the issue of any series of Preferred Stock, after payment shall
have been made to the holders of Preferred Stock of the full amount of dividends

of all such shares of Stock present in person or by proxy may adjourn any
meeting from time to time until a quorum shall attend.  At any such adjourned

shall at every meeting of the stockholders be entitled to one vote for each
share of Stock to participate in such vote held by such stockholder on the
record date.  Every stockholder entitled to vote shall have the right to vote in
person or by proxy.  Except as otherwise provided by law, no vote on any
question upon which a vote of the stockholders may be taken need be by ballot
unless the chairman of the meeting shall determine that it shall be by ballot or
the holders of a majority of the shares of Stock present in person or by proxy
and entitled to participate in such vote shall so demand.  In a vote by ballot
each ballot shall state the number of shares voted and the name of the
stockholder or proxy voting.  Unless otherwise provided by law or by the

corporate action may be taken with the written consent of the stockholders of
Stock having not less than the minimum percentage of the total vote required by
statute for the proposed corporate action, unless the Certificate of
Incorporation or the By-Laws require a greater percentage for such action, in
which case the consent shall be that of the holders of such greater percentage;
provided, however, that prompt notice is given to all the stockholders who have
not consented of the taking of such corporate action without a meeting and by
less than unanimous written consent.

                                 W I T N E S S E T H:

         WHEREAS, the Company proposes to issue to the Representative, in its
individual capacity and not as representative of the several Underwriters
(defined below), warrants ("Warrants") to purchase up to 125,000 (as such number
may be adjusted from time to time pursuant to Article 8 of this Agreement)
shares (the "Shares") of common stock, $.001 par value per share, of the Company
(the "Common Stock"); and

         WHEREAS, the Representative has agreed, pursuant to the underwriting
agreement (the "Underwriting Agreement") dated ____________ __, 1998 between the
Representative, as representative of the several underwriters named in Schedule
A to the Underwriting Agreement (the "Underwriters"), and the Company, to act as
representative of the several Underwriters in connection with the Company's
proposed public offering (the "Public Offering") of 1,250,000 shares of Common
Stock (the "Public Shares") at an initial public offering price of $____ per
share; and

         WHEREAS, the Warrants issued pursuant to this Agreement are being
issued by the Company to the Representative and/or to its designees who are
officers or partners of the Representative and/or, at the Representative's
direction, to members of the selling group or underwriting syndicate
participating in the distribution of the Public Shares in the Public Offering
and/or their respective officers or partners (collectively, the "Designees"), in
consideration for, and as part of the Representative's compensation in
connection with, the Representative's acting as representative of the several
Underwriters pursuant to the Underwriting Agreement;

         NOW, THEREFORE, in consideration of the premises, the payment by the
Representative or the Designees to the Company of ONE HUNDRED AND TWENTY-FIVE
DOLLARS ($125), the agreements herein set forth and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

         1.   Grant.  

         The Representative and/or the Designees are hereby granted the right
to purchase, at any time from ___________, 1999 until 5:00 P.M., New York City
time, on ___________, 2003, (the "Warrant Exercise Term"), up to 125,000 fully
paid and non-assessable Shares at an initial exercise price (subject to 

<PAGE>

adjustment as provided in Article 8 hereof) of $_______ per Share.

         2.   Warrant Certificates.  

         The warrant certificates  delivered and to be delivered pursuant to
this Agreement (the "Warrant Certificates") shall be in the form set forth as
Exhibit A attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as required or
permitted by this Agreement.

         3.   Exercise of Warrants.  

              3.1  Cash Exercise.  The Warrants initially are exercisable at a
price of $______ per Share, payable in cash or by check to the order of the
Company, or any combination of thereof, subject to adjustment as provided in
Article 8 hereof.  Upon surrender of a Warrant Certificate with the annexed Form
of Election to Purchase duly executed, together with payment of the Exercise
Price (as hereinafter defined) for the Shares purchased, at the Company's
principal offices (currently located at 1737 N. First Street, Suite 290, San
Jose, California 95112) the registered holder of a Warrant Certificate ("Holder"
or "Holders") shall be entitled to receive a certificate or certificates for the
Shares so purchased.  The  purchase rights represented by each Warrant
Certificate are exercisable at the option of the Holder thereof, in whole or in
part (but not as to fractional shares of the Common Stock).  In the case of the
purchase of less than all the Shares purchasable under any Warrant Certificate,
the Company shall cancel said Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the Shares purchasable thereunder.

              3.2  Cashless Exercise.  At any time during the Warrant Exercise
Term, the Holder may, at the Holder's option, exchange, in whole or in part, the
Warrants represented by such Holder's Warrant Certificate (a "Warrant
Exchange"), into the number of Shares determined in accordance with this Section
3.2, by surrendering such Warrant Certificate at the principal office of the
Company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Warrants to be so
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange").  The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date").  Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new Warrant
Certificate of like tenor representing the Warrants which were subject to the
surrendered Warrant Certificate and not included in the Warrant Exchange, shall
be issued as of the Exchange Date 

                                          -2-
<PAGE>

and delivered to the Holder within three (3) days following the Exchange Date. 
In connection with any Warrant Exchange, the Holder shall be entitled to
subscribe for and acquire (i) the number of Shares (rounded to the next highest
integer) which would, but for the Warrant Exchange, then be issuable pursuant to
the provisions of Section 3.1 above upon the exercise of the Warrants specified
by the Holder in its Notice of Exchange (the "Total Number") less (ii) the
number of Shares equal to the quotient obtained by dividing (a) the product of
the Total Number and the existing Exercise Price (as hereinafter defined) by (b)
the Market Price (as hereinafter defined) of a Public Share on the day preceding
the Warrant Exchange.  "Market Price" at any date shall be deemed to be the last
reported sale price, or, in case no such reported sales takes place on such day,
the average of the last reported sale prices for the last three (3) trading
days, in either case as officially reported by the principal securities exchange
on which the Common Stock is listed or admitted to trading or as reported in the
NASDAQ National Market System, or, if the Common Stock is not listed or admitted
to trading on any national securities exchange or quoted on the NASDAQ National
Market System, the closing bid price as furnished by (i) the National
Association of Securities Dealers, Inc. through NASDAQ or (ii) a similar
organization if NASDAQ is no longer reporting such information.

         4.   Issuance of Certificates.  

         Upon the exercise of the Warrants, the issuance of certificates for
the Shares purchased shall be made forthwith (and in any event within three (3)
business days thereafter) without charge to the Holder thereof including,
without limitation, any tax which may be payable in respect of the issuance
thereof, and such certificates shall (subject to the provisions of Article 5
hereof) be issued in the name of, or in such names as may be directed by, the
Holder thereof; provided, however, that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any such certificates in a name other than that of the Holder
and the Company shall not be required to issue or deliver such certificates
unless or until the person or persons requesting the issuance thereof shall have
paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

         The Warrant Certificates and the certificates representing the Shares
shall be executed on behalf of the Company by the manual or facsimile signature
of the present or any future Chairman or Vice Chairman of the Board of Directors
or President or Vice President of the Company under its corporate seal
reproduced thereon, attested to by the manual or facsimile signature of the
present or any future Secretary or Assistant Secretary of the Company.  Warrant
Certificates shall be dated 

                                          -3-
<PAGE>

the date of execution by the Company upon initial issuance, division, exchange,
substitution or transfer.

         Upon exercise, in part or in whole, of the Warrants, certificates
representing the Shares shall bear a legend substantially similar to the
following:

    "The securities represented by this certificate and the other
    securities issuable upon exercise thereof have not been registered for
    purposes of public distribution under the Securities Act of 1933, as
    amended (the "Act"), and may not be offered or sold except (i)
    pursuant to an effective registration statement under the Act, (ii) to
    the extent applicable, pursuant to Rule 144 under the Act (or any
    similar rule under such Act relating to the disposition of
    securities), or (iii) upon the delivery by the holder to the Company
    of an opinion of counsel, reasonably satisfactory to counsel to the
    Company, stating that an exemption from registration under such Act is
    available."

         5.   Restriction on Transfer of Warrants.  

         The Holder of a Warrant Certificate, by the Holder's acceptance
thereof, covenants and agrees that the Warrants are being acquired as an
investment and not with a view to the distribution thereof, and that the
Warrants may not be sold, transferred, assigned, hypothecated or otherwise
disposed of, in whole or in part, for a period of one (1) year from the date
hereof, except to the Designees.

         6.   Price.

              6.1. Initial and Adjusted Exercise Price.  The initial exercise
price of each Warrant shall be $____ per Share.  The adjusted exercise price per
Share shall be the price which shall result from time to time from any and all
adjustments of the initial exercise price in accordance with the provisions of
Article 8 hereof.

              6.2. Exercise Price.  The term "Exercise Price" herein shall mean
the initial exercise price or the adjusted exercise price, depending upon the
context.

         7.   Registration Rights.

              7.1. Registration Under the Securities Act of 1933.  None of the
Warrants or Shares have been registered for purposes of public distribution
under the Securities Act of 1933, as amended (the "Act"). 

              7.2. Registrable Securities.  As used herein the term
"Registrable Security" means each of the Warrants, the 

                                          -4-
<PAGE>

Shares and any shares of Common Stock issued upon any stock split or stock
dividend in respect of such Shares; provided, however, that with respect to any
particular Registrable Security, such security shall cease to be a Registrable
Security when, as of the date of determination, (i) it has been effectively
registered under the Act and disposed of pursuant thereto, (ii) registration
under the Act is no longer required for the subsequent public distribution of
such security or (iii) it has ceased to be outstanding.  The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security."  In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Article 7.

              7.3. Piggyback Registration.  If, at any time during the seven
years following the effective date of the Public Offering, the Company proposes
to prepare and file one or more post-effective amendments to the registration
statement filed in connection with the Public Offering or any new registration
statement or post-effective amendments thereto covering equity or debt
securities of the Company, or any such securities of the Company held by its
shareholders (in any such case, other than in connection with a merger,
acquisition or pursuant to Form S-8 or successor form) (for purposes of this
Article 7, collectively, the "Registration Statement"), it will give written
notice of its intention to do so by registered mail ("Notice"), at least thirty
(30) business days prior to the filing of each such Registration Statement, to
all holders of the Registrable Securities.  Upon the written request of such a
holder (a "Requesting Holder"), made within twenty (20) business days after
receipt of the Notice, that the Company include any of the Requesting Holder's
Registrable Securities in the proposed Registration Statement, the Company
shall, as to each such Requesting Holder, use its best efforts to effect the
registration under the Act of the Registrable Securities which it has been so
requested to register ("Piggyback Registration"), at the Company's sole cost and
expense and at no cost or expense to the Requesting Holders.

         Notwithstanding the provisions of this Section 7.3, the Company shall
have the right at any time after it shall have given written notice pursuant to
this Section 7.3 (irrespective of whether any written request for inclusion of
Registrable Securities shall have already been made) to elect not to file any
such proposed Registration Statement, or to withdraw the same after the filing
but prior to the effective date thereof.

              7.4. Demand Registration.

                   (a)  At any time during the Warrant Exercise Term, any
"Majority Holder" (as such term is defined in Section 

                                          -5-
<PAGE>

7.4(c) below) of the Registrable Securities shall have the right (which right is
in addition to the piggyback registration rights provided for under Section 7.3
hereof), exercisable by written notice to the Company (the "Demand Registration
Request"), to have the Company prepare and file with the Securities and Exchange
Commission (the "Commission"), on one occasion, at the sole expense of the
Company (except as provided in Section 7.5(b) hereof), a Registration Statement
and such other documents, including a prospectus, as may be necessary (in the
opinion of both counsel for the Company and counsel for such Majority Holder),
in order to comply with the provisions of the Act, so as to permit a public
offering and sale of the Registrable Securities by the holders thereof.  The
Company shall use its best efforts to cause the Registration Statement to become
effective under the Act, so as to permit a public offering and sale of the
Registrable Securities by the holders thereof.  Once effective, the Company will
use its best efforts to maintain the effectiveness of the Registration Statement
until the earlier of (i) the date that all of the Registrable Securities have
been sold or (ii) the date that the holders of the Registrable Securities
receive an opinion of counsel to the Company that all of the Registrable
Securities may be freely traded (without limitation or restriction as to
quantity or timing and without registration under the Act) under Rule 144(k)
promulgated under the Act or otherwise.  

                   (b)  The Company covenants and agrees to give written notice
of any Demand Registration Request to all holders of the Registrable Securities
within ten (10) business days from the date of the Company's receipt of any such
Demand Registration Request.  After receiving notice from the Company as
provided in this Section 7.4(b), holders of Registrable Securities may request
the Company to include their Registrable Securities in the Registration
Statement to be filed pursuant to Section 7.4(a) hereof by notifying the Company
of their decision to have such securities included within ten (10) days of their
receipt of the Company's notice.

                   (c)  The term "Majority Holder" as used in Section 7.4
hereof shall mean any holder or any combination of holders of Registrable
Securities, if included in such holders' Registrable Securities are that
aggregate number of Shares (including Shares already issued and Shares issuable
pursuant to the exercise of outstanding Warrants) as would constitute a majority
of the aggregate number of Shares (including Shares already issued and Shares
issuable pursuant to the exercise of outstanding Warrants) included in all the
Registrable Securities.

              7.5. Covenants of the Company With Respect to Registration.  The
Company covenants and agrees as follows:

                   (a)  In connection with any registration under Section 7.4
hereof, the Company shall file the Registration 

                                          -6-
<PAGE>

Statement as expeditiously as possible, but in any event no later than twenty
(20) business days following receipt of any demand therefor, shall use its best
efforts to have any such Registration Statement declared effective at the
earliest possible time, and shall furnish each holder of Registrable Securities
such number of prospectuses as shall reasonably be requested.

                   (b)  The Company shall pay all costs, fees and expenses
(other than underwriting fees, discounts and nonaccountable expense allowances
applicable to the Registrable Securities and the fees and expenses of counsel
retained by the holders of the Registrable Securities) in connection with all
Registration Statements filed pursuant to Sections 7.3 and 7.4(a) hereof
including, without limitation, the Company's legal and accounting fees, printing
expenses, and blue sky fees and expenses. 

                   (c)  The Company will take all necessary action which may be
required in qualifying or registering the Registrable Securities included in the
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are reasonably requested by the holders of such
securities.

                   (d)  The Company shall indemnify any holder of the
Registrable Securities to be sold pursuant to any Registration Statement and any
underwriter or person deemed to be an underwriter under the Act and each person,
if any, who controls such holder or underwriter or person deemed to be an
underwriter within the meaning of Section 15 of the Act or Section 20(a) of the
Securities Exchange Act of 1934, as amended ("Exchange Act"), against all loss,
claim, damage, expense or liability (including all expenses reasonably incurred
in investigating, preparing or defending against any claim whatsoever) to which
any of them may become subject under the Act, the Exchange Act or otherwise,
arising from such registration statement to the same extent and with the same
effect as the provisions pursuant to which the Company has agreed to indemnify
the Underwriters as set forth in Section 7 of the Underwriting Agreement and to
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

                   (e)  Any holder of Registrable Securities to be sold
pursuant to a Registration Statement, and such Holder's successors and assigns,
shall severally, and not jointly, indemnify, the Company, its officers and
directors and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss,
claim, damage or expense or liability (including all expenses reasonably
incurred in investigating, preparing or defending against any claim whatsoever)
to which they may become subject under the Act, the Exchange Act or otherwise,
arising from information furnished by or on behalf of such Holder, or such 

                                          -7-
<PAGE>

Holder's successors or assigns, for specific inclusion in such Registration
Statement to the same extent and with the same effect as the provisions pursuant
to which the Underwriters have agreed to indemnify the Company as set forth in
Section 7 of the Underwriting Agreement and to provide for just and equitable
contribution as set forth in Section 8 of the Underwriting Agreement.

                   (f)  Nothing contained in this Agreement shall be construed
as requiring any Holder to exercise the Warrants held by such Holder prior to
the initial filing of any Registration Statement or the effectiveness thereof.

                   (g)  If the Company shall fail to comply with the provisions
of this Section 7 the Company shall, in addition to any other equitable or other
relief available to the holders of Registrable Securities, be liable for any or
all incidental, special and consequential damages sustained by the holders of
Registrable Securities, requesting registration of their securities.

                   (h)  The Company shall promptly deliver copies of all
correspondence between the Commission and the Company, its counsel or auditors
and all memoranda relating to discussions with the Commission or its staff with
respect to the Registration Statement to each Holder of Registrable Securities
included for registration in such Registration Statement pursuant to Section 7.3
hereof or Section 7.4 hereof that requests such correspondence and memoranda and
to the managing underwriter, if any, of the offering in connection with which
such Holder's Registrable Securities are being registered and shall permit each
such Holder and managing underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
Registration Statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc.  Such investigation shall include access to books, records and
properties and opportunities to discuss the business of the Company with its
officers and independent auditors, all to such reasonable extent and at such
reasonable times and as often as any such Holder or managing underwriter shall
reasonably request.

              8.   Adjustments of Exercise Price and Number of Shares.

              8.1  Computation of Adjusted Price.  In case the Company shall at
any time after the date hereof pay a dividend in shares of Common Stock or make
a distribution in shares of Common Stock, then upon such dividend or
distribution, the Exercise Price in effect immediately prior to such dividend or
distribution shall forthwith be reduced to a price determined by dividing:

                                          -8-
<PAGE>

                        (a) an amount equal to the total number of shares of
Common Stock outstanding immediately prior to such dividend or distribution
multiplied by the Exercise Price in effect immediately prior to such dividend or
distribution, by
                        (b) the total number of shares of Common Stock
outstanding immediately after such issuance or sale.

                   For the purposes of any computation to be made in accordance
with the provisions of this Section 8.1, the Common Stock issuable by way of
dividend or other distribution on any stock of the Company shall be deemed to
have been issued immediately after the opening of business on the date following
the date fixed for the determination of stockholders entitled to receive such
dividend or other distribution.

              8.2. Subdivision and Combination.  In case the Company shall at
any time subdivide or combine the outstanding shares of Common Stock, the
Exercise Price shall forthwith be proportionately decreased in the case of
subdivision or increased in the case of combination.

              8.3. Adjustment in Number of Shares.  Upon each adjustment of the
Exercise Price pursuant to the provisions of this Article 8, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full number by multiplying a number equal to the Exercise Price in
effect immediately prior to such adjustment by the number of Shares issuable
upon exercise of the Warrants immediately prior to such adjustment and dividing
the product so obtained by the adjusted Exercise Price.

              8.4. Reclassification, Consolidation, Merger, etc.  In case of 
any reclassification or change of the outstanding shares of Common Stock 
(other than a change in par value to no par value, or from no par value to 
par value, or as a result of a subdivision or combination), or in the case of 
any consolidation of the Company with, or merger of the Company into, another 
corporation (other than a consolidation or merger in which the Company is the 
surviving corporation and which does not result in any reclassification or 
change of the outstanding shares of Common Stock, except a change as a result 
of a subdivision or combination of such shares or a change in par value, as 
aforesaid), or in the case of a sale or conveyance to another corporation of 
the property of the Company as an entirety, the Holders shall thereafter have 
the right to purchase the kind and number of shares of stock and other 
securities and property receivable upon such reclassification, change, 
consolidation, merger, sale or conveyance as if the Holders were the owners 
of the shares of Common Stock underlying the Warrants immediately prior to 
any such events at a price equal to the product of (x) the number of shares 
of Common Stock issuable upon exercise of the Holder's Warrants and (y) the 
Exercise Price in effect immediately prior to the record date for such 
reclassification,

                                          -9-
<PAGE>

change, consolidation, merger, sale or conveyance as if such Holders had 
exercised the Warrants.

              8.5.  Determination of Outstanding Shares of Common Stock.  The
number of shares of Common Stock at any one time outstanding shall include the
aggregate number of shares of Common Stock issued and the aggregate number of
shares of Common Stock issuable upon the exercise of options, rights, warrants
and upon the conversion or exchange of convertible or exchangeable securities.

              8.6. Dividends and Other Distributions with Respect to
Outstanding Securities.  In the event that the Company shall at any time prior
to the exercise of all Warrants make any distribution of its assets to holders
of its Common Stock as a liquidating or a partial liquidating dividend, then the
holder of Warrants who exercises its Warrants after the record date for the
determination of those holders of Common Stock entitled to such distribution of
assets as a liquidating or partial liquidating dividend shall be entitled to
receive for the Warrant Price per Warrant, in addition to each share of Common
Stock, the amount of such distribution (or, at the option of the Company, a sum
equal to the value of any such assets at the time of such distribution as
determined by the Board of Directors of the Company in good faith) which would
have been payable to such holder had he been the holder of record of the Common
Stock receivable upon exercise of his Warrant on the record date for the
determination of those entitled to such distribution.  At the time of any such
dividend or distribution, the Company shall make appropriate reserves to ensure
the timely performance of the provisions of this Subsection 8.6.

              8.7. Subscription Rights for Shares of Common Stock or Other
Securities.  In the case the Company or an affiliate of the Company shall at any
time after the date hereof and prior to the exercise of all the Warrants issue
any rights, warrants or options to subscribe for shares of Common Stock or any
other securities of the Company or of such affiliate to all the shareholders of
the Company, the Holders of unexercised Warrants on the record date set by the
Company or such affiliate in connection with such issuance of rights, warrants
or options shall be entitled, in addition to the shares of Common Stock or other
securities receivable upon the exercise of the Warrants, to receive such rights,
warrants or options that such Holders would have been entitled to receive had
they been, on such record date, the holders of record of the number of whole
shares of Common Stock then issuable upon exercise of their outstanding Warrants
(assuming for purposes of this Section 8.7), that the exercise of the Warrants
is permissible immediately upon issuance).

         9.   Exchange and Replacement of Warrant Certificates.


                                          -10-
<PAGE>

         Each Warrant Certificate is exchangeable without expense, upon the
surrender thereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrant
Certificate, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

         10.  Elimination of Fractional Interests.

         The Company shall not be required to issue certificates representing
fractions of Shares, nor shall it be required to issue scrip or pay cash in lieu
of fractional interests, it being the intent of the parties that all fractional
interests shall be eliminated by rounding any fraction up to the nearest whole
number of Shares.

         11.  Reservation and Listing of Securities.

         The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof.  The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all Shares
issuable upon such exercise shall be duly and validly issued, fully paid,
non-assessable and not subject to the preemptive rights of any shareholder.  As
long as the Warrants shall be outstanding, the Company shall use its best
efforts to cause all shares of Common Stock issuable upon the exercise of the
Warrants to be listed on or quoted by Nasdaq or listed on such national
securities exchange in the event the Common Stock is listed on a national
securities exchange.

         12.  Notices to Warrant Holders.

         Nothing contained in this Agreement shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive notice
as a shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company.  If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

                                          -11-
<PAGE>

              (a)  the Company shall take a record of the holders of its shares
of Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the
Company; or

              (b)  the Company shall offer to all the holders of its Common
Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or
any option, right or warrant to subscribe therefor; or

              (c)  a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business as an entirety shall be
proposed; or

              (d)  reclassification or change of the outstanding shares of 
Common Stock (other than a change in par value to no par value, or from no 
par value to par value, or as a result of a subdivision or combination), 
consolidation of the Company with, or merger of the Company into, another 
corporation (other than a consolidation or merger in which the Company is the 
surviving corporation and which does not result in any reclassification or 
change of the outstanding shares of Common Stock, except a change as a result 
of a subdivision or combination of such shares or a change in par value, as 
aforesaid), or a sale or conveyance to another corporation of the property of 
the Company as an entirety is proposed; or

              (e)  The Company or an affiliate of the Company shall propose 
to issue any rights to subscribe for shares of Common Stock or any other 
securities of the Company or of such affiliate to all the shareholders of the 
Company;

then, in any one or more of said events, the Company shall give written notice
to the Holder or Holders of such event at least fifteen (15) days prior to the
date fixed as a record date or the date of closing the transfer books for the
determination of the shareholders entitled to such dividend, distribution,
convertible or exchangeable securities or subscription rights, options or
warrants, or entitled to vote on such proposed dissolution, liquidation, winding
up or sale.  Such notice shall specify such record date or the date of closing
the transfer books, as the case may be.  Failure to give such notice or any
defect therein shall not affect the validity of any action taken in connection
with the declaration or payment of any such dividend or distribution, or the
issuance of any convertible or exchangeable securities or subscription rights,
options or warrants, or any proposed dissolution, liquidation, winding up or
sale.

                                 WARRANT CERTIFICATE

         This Warrant Certificate certifies that _______________ ____________
or registered assigns, is the registered holder of _______ Warrants to purchase,
at any time from ____________ __, 1999 until 5:00 P.M. New York City time on
_____________ __, 2003 ("Expiration Date"), up to _____ fully-paid and
non-assessable shares (the "Shares") of common stock, par value $.001 per
share(the "Common Stock"), of AyurCore, Inc., a Delaware corporation (the
"Company"), at the initial exercise price, subject to adjustment in certain
events (the "Exercise Price"), of $____ per Share upon surrender of this Warrant
Certificate and payment of the Exercise Price at an office or agency of the
Company, but subject to the conditions set forth herein and in the warrant
agreement dated as of ___________, 1998 between the Company and LT Lawrence &
Co., Inc. (the "Warrant Agreement").  Payment of the Exercise Price may be made
in cash, or by certified or official bank check in New York Clearing House funds
payable to the order of the Company, or any combination thereof.

         No Warrant may be exercised after 5:00 P.M., New York City time, on
the Expiration Date, at which time all Warrants evidenced hereby, unless
exercised prior thereto, shall thereafter be void.

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to in a description of the rights, limitation
of 

<PAGE>

rights, obligations, duties and immunities thereunder of the Company and the
holders (the words "holders" or "holder" meaning the registered holders or
registered holder) of the Warrants.

         The Warrant Agreement provides that upon the occurrence of certain
events, the Exercise Price and the type and/or number of the Company's
securities issuable thereupon may, subject to certain conditions, be adjusted. 
In such event, the Company will, at the request of the holder, issue a new
Warrant Certificate evidencing the adjustment in the Exercise Price and the
number and/or type of securities issuable upon the exercise of the Warrants;
provided, however, that the failure of the Company to issue such new Warrant
Certificates shall not in any way change, alter, or otherwise impair, the rights
of the holder as set forth in the Warrant Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax, or other governmental charge
imposed in connection therewith.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

    employee shall assign, or offer to assign, any of his or his rights in an
    invention to his or her employer shall not apply to an invention that the
    employee developed entirely on his or her own time without using the
    employer's equipment, supplies, facilities, or trade secret information
    except for those inventions that either:

         "(1) Relate at the time of conception or reduction to practice of the
         invention to the employer's business, or actual or demonstrably
         anticipated research or development of the employer; or
         
         "(2) Result from any work performed  by the employee for the employer.
         
    "(b) The extent a provision in an employment agreement purports to require
    an employee to assign an invention otherwise excluded from being required
    to be assigned under subdivision (a), the provision is against the public
    policy of this state and is unenforceable."
    
The provisions of this Section shall apply only to the extent that the place 
at which Employee performs his services under this Agreement is located in 
the State of California and only with respect to services performed in the 
State of California.

Agreement shall include the period during which Employee in fact so continues 
in such employment; provided that the continuation of employment with the 
Company for any period after the End Date shall not obligate the Company to

particular period after the End Date.

    9.2.   Termination by the Company.  The Company may terminate this 
Agreement for "cause" at any time by giving to Employee ninety (90) days 
prior written notice of termination.  For purposes of this Section, the term

disability, as a result of which Employee is prevented from fully performing 
Employee's services under this Agreement for a consecutive period of sixty

twelve-month period.  This Agreement shall terminate automatically at the end 
of such 90-day period and the Company shall have no obligation to give

obligation of the Company under this Agreement.  Employee may terminate this

except as provided in Section 12 hereof.

    9.5.   Related Agreements.  The Company may grant to Employee one or more 
stock options, or other stock incentives which may provide that the option, 
or stock incentive will vest over a period of time which may be different 
from the then remaining term of this Agreement.  Employee acknowledges that 
nothing in this Agreement or any agreement relating to any such option, or 
stock incentive (a) shall obligate the Company to continue Employee's 
employment for a period sufficient to permit the full vesting of such option, 
bonus or stock incentive or (b) shall limit in any way the Company's right to 
terminate Employee's employment in accordance with the terms of this 
Agreement.

    9.6.   Injunctive Relief.  Employee hereby acknowledges and agrees that 
it would be difficult to fully compensate the Company for damages for a 
breach or threatened breach of any of the provisions of Sections 3.2, 6, 7, 
8, 9.3, 11 or 12.3 hereof.  Accordingly, Employee specifically agrees that 
the Company shall be entitled to temporary and permanent injunctive relief to 
enforce the provisions of Sections 3.2, 6, 7, 8, 9.3, 11 and 12.3 hereof and 
that such relief may be granted without the necessity of proving actual 
damages.  The foregoing provision with respect to injunctive relief shall 
not, however, prohibit the Company from pursuing any other rights or remedies 
available to the Company for such breach or threatened breach, including, but 
not limited to, the recovery of damages from Employee or any third parties.

10. Survival of Certain Provisions.  Notwithstanding anything to the contrary 
contained herein, in the event of any termination of this Agreement, the

hereof.

11. Binding Arbitration.

    11.1.  Resolution of Dispute.  All disputes, claims and controversies 
("Claims") between the parties arising from or relating to this Agreement 
shall be resolved by binding arbitration as provided in this Section.  The 
parties each waive their right to commence an action in any court to resolve 
any Claim. However, this Section shall not apply to any  Claim:  (a) for 
worker's compensation or unemployment benefits; or (b) by the Company for 
injunctive and/or other equitable relief.  With respect to matters referred 
to in clause (b) above, the Company may seek and obtain injunctive relief in 
court and then proceed with arbitration under this Agreement.

                                      -9-
<PAGE>

    11.2.  Processing Claim.  A Claim must be processed in the manner set 
forth below, otherwise the Claim shall be void and deemed waived even if 
there is a federal or state statute of limitations which would allow more 
time to pursue the Claim.

           a.  The Claim must initially be raised in writing by Employee to the
    Chief Executive Officer of the Company.  The Company shall respond to the
    Claim within 30 days after the Claim is presented.  If the Company fails to
    respond, it shall be deemed a denial of Employee's Claim.
         
           b.  If Employee is not satisfied with the Company's decision,
    Employee may present the Claim for resolution by arbitration.  If Employee
    desires to proceed to arbitration, Employee must give written notice to the
    Chief Executive Officer of the Company of his intention to arbitrate within
    60 days from either the mailing of the Company's final decision or the
    expiration of the foregoing 30-day period.

    employer's equipment, supplies, facilities, or trade secret information

         "(1) Relate at the time of conception or reduction to practice of the

         anticipated research or development of the employer; or
         
         "(2) Result from any work performed  by the employee for the employer.
         
    "(b) The extent a provision in an employment agreement purports to require
    an employee to assign an invention otherwise excluded from being required

    policy of this state and is unenforceable."

    9.1. Term.  Notwithstanding the date on which this Agreement is actually 
executed by the Company and Employee or the date on which Employee is 
actually appointed as President and Chief Executive Officer by the Board of 
Directors of the Company, the term of this Agreement shall begin as of the 
effective date of the planned initial public offering of the Company's equity 
securities (the "Start Date") and shall continue until the third anniversary 
thereof ("End Date") unless sooner terminated in accordance with the terms of 
this Agreement.  In the event that Employee shall continue in the full-time 
employment of the Company after the End Date, such continued employment shall 
be subject to the terms and conditions of this Agreement and the term of this 
Agreement shall include the period during which Employee in fact so continues 
in such employment; provided that the continuation of employment with the 
Company for any period after the End Date shall not obligate the Company to 
continue to employ Employee or to continue to employ Employee for any 
particular period after the End Date.

    9.2. Termination by the Company.     The Company may terminate this
Agreement for "cause" at any time by giving to Employee ninety (90) days prior
written notice of termination.  For purposes of this Section, the term "cause"
shall mean (a) conviction of or confession by Employee of theft, fraud, or
embezzlement committed against the Company; (b) Employee's refusal or failure to
diligently perform services for the Company under this Agreement; (c) Employee's
material breach of any of her obligations under this Agreement or Employee's
failure or refusal to perform any material obligation of Employee under this
Agreement; and (d) the incapacity or disability of Employee by reason of
accident, illness, or mental or physical disability, as a result of which
Employee is prevented from fully performing Employee's services under this
Agreement for a consecutive period of sixty (60) days or longer or an aggregate
of ninety (90) days or more during any twelve-month period.  This Agreement
shall terminate automatically at the end of such 90-day period and the Company
shall have no obligation to give Employee any further notice of termination.

    9.3. Termination by Employee.     Employee may not terminate this 
Agreement for any reason other than "cause".  For purposes of this Section, 
the term "cause" shall mean the Company's material breach of any of its 
obligations under this Agreement or the Company's failure or refusal to 
perform any material obligation of the Company under this Agreement.  
Employee may terminate this Agreement for "cause" at any time by giving to 
the Company ninety (90) days prior written notice of termination.  This 
Agreement shall terminate automatically at the end of such 90-day period and 
Employee shall have no obligation to give the Company any further notice of 
termination.

    9.4. Effect of Termination.     In the event of the termination of this 
Agreement by the Company or Employee, the Company shall be released and 
discharged of and from all obligations under this Agreement except for its 
obligation to pay to Employee monies due and owing to Employee with respect 
to services performed prior to the date of termination of this Agreement and 
except as provided in Section 12 hereof.

    9.5. Related Agreements.     The Company may grant to Employee one or more
stock options, or other stock incentives which may provide that the option, or
stock incentive will vest over a period of time which may be different from the
then remaining term of this Agreement.  Employee acknowledges that nothing in
this Agreement or any agreement relating to any such option, or stock incentive
(a) shall obligate the Company to continue Employee's employment for a period
sufficient to permit the full vesting of such option, bonus or stock incentive
or (b) shall limit in any way the Company's right to terminate Employee's
employment in accordance with the terms of this Agreement.

    9.6. Injunctive Relief.     Employee hereby acknowledges and agrees that it
would be difficult to fully compensate the Company for damages for a breach or
threatened breach of any of the provisions of Sections 3.2, 6, 7, 8, 9.3, 11 or
12.3 hereof.  Accordingly, Employee specifically agrees that the Company shall
be entitled to temporary and permanent injunctive relief to enforce the
provisions of Sections 3.2, 6, 7, 8, 9.3, 11 and 12.3 hereof and that such
relief may be granted without the necessity of proving actual damages.  The
foregoing provision with respect to injunctive relief shall not, however,
prohibit the Company from pursuing any other rights or remedies available to the
Company for such breach or threatened breach, including, but not limited to, the
recovery of damages from Employee or any third parties.

10. Survival of Certain Provisions.     Notwithstanding anything to the
contrary contained herein, in the event of any termination of this Agreement,
the Company shall retain all of its rights under Section 6, 7, 8, 10, 11 and 12
hereof.

11. Binding Arbitration.

    11.1.     Resolution of Dispute.     All disputes, claims and controversies
("Claims") between the parties arising from or relating to this Agreement shall
be resolved by binding arbitration as provided in this Section.  The parties
each waive their right to commence an action in any court to resolve any Claim. 
However, this Section shall not apply to any  Claim:  (a) for worker's
compensation or unemployment benefits; or (b) by the Company for injunctive
and/or other equitable relief.  With respect to matters referred to in clause
(b) above, the Company may seek and obtain injunctive relief in court and then
proceed with arbitration under this Agreement.

    11.2.     Processing Claim.     A Claim must be processed in the manner set
forth below, otherwise the Claim shall be void and deemed waived even if there
is a federal or state statute of limitations which would allow more time to
pursue the Claim.



                                         -9-
<PAGE>

         a.   The Claim must initially be raised in writing by Employee to the
    Board of Directors of the Company.  The Company shall respond to the Claim
    within 30 days after the Claim is presented.  If the Company fails to
    respond, it shall be deemed a denial of Employee's Claim.
         
         b.   If Employee is not satisfied with the Company's decision,
    Employee may present the Claim for resolution by arbitration.  If Employee
    desires to proceed to arbitration, Employee must give written notice to the
    Board of Directors of the Company of her intention to arbitrate within 60
    days from either the mailing of the Company's final decision or the
    expiration of the foregoing 30-day period.
         
         c.   If the Company desires to initiate arbitration, it must give
    written notice to Employee within 60 days after either its mailing to
    Employee of notice of its final decision or the expiration of the foregoing
    30-day period.
         
    11.3.     Procedure.     The arbitration shall be conducted in accordance
with the then-current Model Employment Arbitration Procedures of the American
Arbitration Association ("AAA") before a single arbitrator.  The arbitration
shall take place in San Jose, California.

    11.4.     Discovery Matters.     Each party shall have the right to take
the deposition of three individuals and any expert witness designated by the
other party.  Each party also shall have the right to make requests for
production of documents to any party.  Additional discovery may be had only
where the arbitrator so orders, upon a showing of substantial need.

    11.5.     Limitation.     The arbitrator shall have no authority to: (a)
adopt new policies or procedures for the Company; (b) modify this Agreement or
any existing policies, procedures, wages or benefits of the Company; or (c) hear
or decide any matter that was not processed in accordance with this Agreement. 
The arbitrator shall have the authority to award any form of remedy or damages
that would be available in a court; provided that Employee shall not seek and
the arbitrator shall have no authority to award punitive or exemplary damages.

    11.6.     Costs.     The Company and Employee each shall pay one-half of
all reasonable and necessary fees of the arbitral body and arbitrator.

    11.7.     Confidential Proceedings.     The arbitration shall be conducted
in private, and shall not be open to the public or the media.  The testimony and
other evidence presented, and the results of the arbitration, unless otherwise
agreed to by both parties, shall be confidential and, unless otherwise required
by law, shall not be made public or reported by either the Company or Employee.

12. Miscellaneous.

may have.  Neither party hereto shall be deemed to waive any rights or remedies
under this Agreement unless such waiver is in writing and is signed by such
party.  No delay or omission on the part of either party hereto in exercising
any right or remedy shall operate as a waiver of such right or remedy or of any
other right or remedy.  A waiver of any right or remedy on any one occasion
shall not be construed as a bar to or waiver of any such right or remedy on any
future occasion.

    12.5.     Severability.     If any provision or portion thereof of this
Agreement is held to be unenforceable or invalid, the remaining provisions and
portions thereof shall nevertheless be given and continue in full force and

                                    AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    1.   Purpose of the Plan.

         The purpose of the AyurCore, Inc. 1997 Stock Option Plan (the 
"Plan") is to advance the interests of AyurCore, Inc., a Delaware corporation 
(the "Company"), by providing an opportunity for ownership of the stock of 
the Company by employees, agents and directors of, and consultants to, the 
Company or of any subsidiary corporation (herein called "subsidiary" or 
"subsidiaries"), as defined in Section 424(f) of the Internal Revenue Code of 
1986, as amended (the "Code") and the Treasury regulations promulgated 
thereunder (the "Regulations").  Such employees, agents and directors of, and 
consultants to, the Company or any subsidiary are hereinafter referred to 
individually as an "Eligible Person" and collectively as "Eligible Persons".  
By providing an opportunity for such stock ownership, the Company seeks to 
attract and retain qualified personnel, and otherwise to provide additional 
incentive for optionees to promote the success of its business.

    2.   Stock Subject to the Plan.

         (a)  The total number of shares of the authorized but unissued or 
treasury shares of the common stock, having no par value per share, of the 
Company (the "Common Stock") for which options may be granted under the Plan 
(the "Options") shall be 227,986, subject to adjustment as provided in 
Section 13 hereof.

         (b)  If an Option granted or assumed hereunder shall expire or 
terminate for any reason without having been exercised in full, the 
unpurchased shares subject thereto shall again be available for subsequent 
Option grants under the Plan.

         (c)  Common Stock issuable upon exercise of an Option may be subject 
to such restrictions on transfer, repurchase rights or other conditions or 
restrictions as shall be determined by the Board of Directors of the Company 
(the "Board").

    3.   Administration of the Plan.

         (a)  The Plan shall be administered by the Board.  No member of the 
Board shall act upon any matter affecting any Option granted or to be granted 
to himself or herself under the Plan; provided, however, that nothing 
contained herein shall be deemed to prohibit a member of the Board from 
acting upon any matter generally affecting the Plan or any Options granted 
thereunder.  A majority of the members of the Board shall constitute a 
quorum, and any action may be taken by a majority of those present and voting 
at any meeting.  The decision of the Board as to all questions of 
interpretation and application of the Plan shall be final, binding and 
conclusive on all persons.  The Board, in its sole discretion, may grant 
Options to purchase shares of the Common Stock only as provided in the Plan, 
and shares shall be issued upon exercise of such Options as provided in the 
Plan.  The Board shall have authority, subject to the express provisions of 
the Plan, to determine the Eligible 

<PAGE>

Persons who shall be issued Options, the times when Options shall be granted 
and within which they may be exercised, the prices at which Options shall be 
exercised, the number of shares of Common Stock to be subject to each Option 
and whether an Option shall be treated as an incentive stock option or a 
non-qualified stock option.  The Board shall also have the authority, subject 
to the express provisions of the Plan, to amend the Plan, to determine the 
terms and provisions of the respective option agreements, which may but need 
not be identical, to construe the respective option agreements and the Plan, 
and to make all other determinations in the judgment of the Board necessary 
or desirable for the administration of the Plan.  The Board may correct any 
defect or supply any omission or reconcile any inconsistency in the Plan or 
in any option agreement in the manner and to the extent it shall deem 
expedient to implement the Plan and shall be the sole and final judge of such 
expediency. The Board, in its discretion, may delegate its power, duties and 
responsibilities to a committee, consisting solely of two or more 
"Non-Employee Directors" (as hereinafter defined).  If a committee is so 
appointed, all references to the Board herein shall mean and relate to such 
committee.  The existence of such a committee shall not affect the power or 
authority of the Board to administer the Plan.  For the purposes of the Plan, 
the term "Non-Employee Director" shall have the meaning ascribed to it in 
paragraph (b)(3) of Rule 16b-3 promulgated under the Securities Exchange Act 
of 1934, as amended (the "Exchange Act"), as such term is interpreted from 
time to time.

    4.   Type of Option.

         Options granted pursuant to the Plan shall be authorized by action 
of the Board and may be designated as either incentive stock options meeting 
the requirements of Section 422 of the Code or non-qualified stock options 
which are not intended to meet the requirements of such Section 422 of the 
Code, the designation to be in the sole discretion of the Board.  Options 
designated as incentive stock options that fail to continue to meet the 
requirements of Section 422 of the Code shall be redesignated as 
non-qualified stock options automatically without further action by the Board 
on the date of such failure to continue to meet the requirements of Section 
422 of the Code.

    5.   Eligibility.

         Options designated as incentive stock options may be granted only to 
Eligible Persons who are officers or employees of the Company or of any 
subsidiary.  Directors who are not otherwise employees of the Company or a 
subsidiary shall not be eligible to be granted incentive stock options 
pursuant to the Plan.  Options designated as non-qualified stock options may 
be granted to any Eligible Person.

         The Board shall take into account such factors as it may deem 
relevant in determining the number of shares of Common Stock to be included 
in an Option to be granted to any Eligible Person.

    6.   Restrictions on Options.

         Incentive stock options (but not non-qualified stock options) 
granted under this Plan shall be subject to the following restrictions:

<PAGE>

         (a)  Limitation on Number of Shares.  The aggregate fair market 
value of the shares of Common Stock with respect to which incentive stock 
options are granted (determined as of the date the incentive stock options 
are granted), exercisable for the first time by an individual during any 
calendar year shall not exceed $100,000.  If an incentive stock option is 
granted pursuant to which the aggregate fair market value of shares with 
respect to which it first becomes exercisable in any calendar year by an 
individual exceeds such $100,000 limitation, the portion of such option which 
is in excess of the $100,000 limitation shall be treated as a non-qualified 
stock option pursuant to Section 422(d)(1) of the Code.  In determining the 
fair market value under this clause (a), the provisions of Section 8 hereof 
shall apply.  In the event that an individual is eligible to participate in 
any other stock option plan of the Company or any subsidiary of the Company 
which is also intended to comply with the provisions of Section 422 of the 
Code, such $100,000 limitation shall apply to the aggregate number of shares 
for which incentive stock options may be granted under this Plan and all such 
other plans.

         (b)  Ten Percent Stockholder.  If any Eligible Person to whom an 
incentive stock option is granted pursuant to the provisions of the Plan is 
on the date of grant the owner of stock (as determined under Section 424(d) 
of the Code) possessing more than 10% of the total combined voting power of 
all classes of stock of the Company or any subsidiary of the Company, then 
the following special provisions shall be applicable to the incentive stock 
options granted to such individual:

              (i)  The Option price per share subject to such Options shall 
be not less than 110% of the fair market value of the shares of Common Stock 
with respect to which Options are granted (determined as of the date such 
Option was granted).  In determining the fair market value under this clause 
(i), the provisions of Section 8 hereof shall apply.

              (ii) The Option by its terms shall not be exercisable after the 
expiration of five years from the date such Option is granted.

    7.   Option Agreement; Disqualifying Dispositions.

         (a)  Each Option shall be evidenced by an option agreement, in a 
form approved from time to time by the Board (the "Agreement"), duly executed 
on behalf of the Company and by the optionee to whom such Option is granted, 
which Agreement shall comply with and be subject to the terms and conditions 
of the Plan.  The Agreement may contain such other terms, provisions and 
conditions which are not inconsistent with the Plan as may be determined by 
the Board; provided that Options designated as incentive stock options shall 
meet all of the conditions for incentive stock options as defined in Section 
422 of the Code.  No Option shall be granted within the meaning of the Plan 
and no purported grant of any Option shall be effective until the Agreement 
shall have been duly executed on behalf of the Company and the optionee.

         (b)  If an optionee makes a "disposition" (within the meaning of 
Section 424(c) of the Code) of shares of Common Stock issued upon exercise of 
an incentive stock option within two years from the date of grant or within 
one year from the date the shares of Common Stock are 

<PAGE>

transferred to the optionee, the optionee shall, within ten days of 
disposition, notify the Board and deliver to it any withholding and 
employment taxes due. However, if the optionee is a person subject to Section 
16(b) of the Exchange Act, delivery of any withholding and employment taxes 
due may be deferred until ten days after the date any income on the 
disposition is recognized under Section 83 of the Code.  The Company may 
cause a legend to be affixed to certificates representing shares of Common 
Stock issued upon exercise of incentive stock options to ensure that the 
Board receives notice of disqualifying dispositions.

    8.   Option Price.

         (a)  The Option price or prices of shares of the Common Stock for 
Options designated as non qualified stock options shall be as determined by 
the Board.

         (b)  Subject to the conditions set forth in Section 6(b) hereof, the 
Option price or prices of shares of the Company's Common Stock designated as 
incentive stock options shall be at least the fair market value of such 
Common Stock on the date the Option is granted as determined by the Board in 
accordance with the Regulations promulgated under Section 422 of the Code.

         (c)  If such shares are then listed on any national securities 
exchange, the fair market value shall be the mean between the high and low 
sales prices, if any, on the largest such exchange on the date of the grant 
of the Option or, if there are no such sales on such date, shall be 
determined by taking a weighted average of the means between the highest and 
lowest sales prices on the nearest date before and the nearest date after the 
date of grant in accordance with Section 25.2512-2 of the Regulations.  If 
the shares are not then listed on any such exchange, the fair market value of 
such shares shall be the mean between the closing "Bid" and the closing "Ask" 
prices, if any, as reported in the National Association of Securities Dealers 
Automated Quotation System ("NASDAQ") for the date of the grant of the 
Option, or, if there are no such prices on such date, shall be determined by 
taking a weighted average of the means between the highest and lowest sales 
prices on the nearest date before and the nearest date after the date of 
grant in accordance with Section 25.2512-2 of the Regulations.  If the shares 
are not then either listed on any such exchange or quoted in NASDAQ, the fair 
market value shall be the mean between the average of the "Bid" and "Ask" 
prices, if any, as reported in the National Association of Securities Dealers 
National Daily Quotation Service for the date of the grant of the Option, or, 
if there are no such prices on such date, shall be determined by taking a 
weighted average of the means between the highest and lowest sales prices on 
the nearest date before and the nearest date after the date of grant in 
accordance with Section 25.2512-2 of the Regulations. If the fair market 
value cannot be determined under the preceding three sentences, it shall be 
determined in good faith by the Board in accordance with Section 422 of the 
Code.

    9.   Manner of Payment; Manner of Exercise.

         (a)  Options granted under the Plan may provide for the payment of 
the exercise price by delivery of (i) cash or a check payable to the order of 
the Company in an amount equal to the exercise price of such Options, (ii) 
shares of Common Stock owned by the optionee having a fair 

<PAGE>

market value (at the date of exercise) equal in amount to the exercise price 
of the Options being exercised, or (iii) any combination of (i) and (ii).  
The fair market value of any shares of Common Stock which may be delivered 
upon exercise of an Option shall be determined by the Board in accordance 
with Section 8 hereof.

         (b)  To the extent that an Option is exercisable, Options may be 
exercised in full at one time or in part from time to time, by giving written 
notice, signed by the person or persons exercising the Option, to the 
Company, stating the number of shares with respect to which the Option is 
being exercised, accompanied by payment in full for such shares as provided 
in Section 9(a) hereof.  No exercise of an Option may be made for fewer than 
100 full shares of Common Stock unless such exercise is made for the entire 
fractional amount of a share remaining to be purchased pursuant to such 
Option.  Upon such exercise, delivery of a certificate for paid-up, 
non-assessable shares shall be made by the Company to the person or persons 
exercising the Option within 20 business days after receipt of such notice by 
the Company.

    10.  Exercise of Options.

         Each Option granted under the Plan shall, subject to Sections 11(b), 
13 and 16 hereof, be exercisable at such time or times and during such period 
as shall be set forth in the Agreement; provided, however, that except as 
otherwise provided pursuant to the provisions of Section 6(b) hereof, no 
Option granted under the Plan shall have a term in excess of ten years from 
the date of grant.

    11.  Term of Options; Exercisability.

         (a)  Term.

              (i)  Each Option shall expire on a date determined by the Board 
which is not more than ten years from the date of the granting thereof, 
except (a) as otherwise provided pursuant to the provisions of Section 6(b) 
hereof, and (b) for earlier termination as herein provided.

              (ii) Except as otherwise provided in this Section 11, an Option 
granted to any optionee who ceases to be an Eligible Person for any reason 
shall terminate on the earlier of (i) three (3) months after the date such 
optionee ceased to be an Eligible Person, or (ii) the date on which the 
Option expires by its terms.

              (iii)     If an optionee ceases to be an Eligible Person 
because the Company has terminated his or her status with the Company for 
cause (as such term is defined in any employment or similar agreement between 
such optionee and the Company or, if there is no such agreement, or such 
agreement does not contain provisions relating to termination or removal for 
cause, as such term is defined by the law of the State of Delaware), such 
Option will, to the extent not terminated, be deemed to have terminated on 
the date immediately preceding the date the optionee ceased to be an Eligible 
Person.

<PAGE>

              (iv) If an optionee ceases to be an Eligible Person because the 
optionee has become disabled (within the meaning of Section 22(e)(3) of the 
Code), such Option shall terminate on the earlier of (i) one year after the 
date such optionee ceased to be an Eligible Person, or (ii) the date on which 
the Option expires by its terms.

              (v)  In the event of the death of any optionee, such Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         (b)  Exercisability.

              (i)  Except as otherwise provided in this Section 11(b), an 
Option granted to an optionee who thereafter ceases to be an Eligible Person 
shall be exercisable only to the extent that the right to purchase shares 
under such Option is exercisable on the date such optionee ceased to be an 
Eligible Person.

              (ii) An Option granted to an optionee who ceases to be an 
Eligible Person because he or she has become disabled (as such term is 
defined in any employment or similar agreement between such optionee and the 
Company or, if there is no such agreement, or such agreement does not contain 
provisions relating to termination or removal for disability, as determined 
by the Board) shall be immediately exercisable as to the full number of 
shares covered by such Option, whether or not under the provisions of the 
Plan or Agreement such Option was otherwise exercisable as of the date of 
disability.

              (iii)     In the event of the death of an optionee, the Option 
granted to such optionee may be exercised as to the full number of shares 
covered by such Option, whether or not under the provisions of the Plan or 
Agreement the optionee was otherwise exercisable at the date of his or her 
death, by the executor, administrator or personal representative of such 
optionee, or by any person or persons who acquired the right to exercise such 
Option by bequest or inheritance or by reason of the death of such optionee.

              (iv) In addition to the acceleration of the exercisability of 
Options pursuant to this Section 11(b) and Section 13(b)(ii) hereof, the 
Board shall have the right, in the exercise of its discretion and for any 
reason, and with the consent of the optionee, to accelerate the date on which 
Options shall be exercisable.

    12.  Transferability.

         The right of any optionee to exercise any Option granted to him or 
her shall not be assignable or transferable by such optionee other than by 
will or the laws of descent and distribution, and any such Option shall be 
exercisable during the lifetime of such optionee only by him or her.  Any 
Option granted under the Plan shall be null and void and without effect upon 
the bankruptcy of the optionee to whom the Option is granted, or upon any 
attempted assignment or transfer, except as herein provided, including, 
without limitation, any purported assignment, whether voluntary or by 

<PAGE>

operation of law, pledge, hypothecation or other disposition, or levy of 
execution, attachment, trustee process or similar process, whether legal or 
equitable, upon such Option.  The Board shall have discretion to grant any 
Option that is not designated as an incentive stock option, free of any or 
all of the restrictions described in this Section.

    13.  Recapitalization, Reorganizations and the Like.

         (a)  In the event that after November 25, 1997 the outstanding 
shares of the Common Stock are changed into or exchanged for a different 
number or kind of shares or other securities of the Company by reason of any 
reorganization, recapitalization, reclassification, stock split, combination 
of shares, or dividends payable in capital stock, appropriate and equitable 
adjustment shall be made by the Board, in its sole discretion, in the number 
and kind of shares as to which Options may be granted under the Plan and as 
to which outstanding Options or portions thereof then unexercised shall be 
exercisable.  Such adjustment in outstanding Options shall be made without 
change in the total price applicable to the unexercised portion of such 
Options and with a corresponding adjustment in the Option price per share.

         (b)  (i)  In addition, unless otherwise determined by the Board in 
its sole discretion, in the case of any (I) merger or consolidation pursuant 
to which the Company's stockholders shall receive cash or securities of 
another corporation and less than 50% of the outstanding capital stock of the 
surviving corporation pursuant to such merger or consolidation shall be owned 
by the stockholders of the Company, (II) sale or conveyance to another entity 
of all or substantially all of the property and assets of the Company or 
(III) Change in Control of the Company, the Company shall, or shall cause 
such surviving corporation or the purchaser(s) of the Company's assets to, 
deliver to the optionee the same kind of consideration that is delivered to 
the stockholders of the Company as a result of such merger, consolidation, 
sale, conveyance or Change in Control, or the Board may cancel all 
outstanding Options in exchange for consideration in cash or marketable 
securities, which consideration in both cases shall be equal in value to the 
value of those shares of stock or other securities the optionee would have 
received had the Option been exercised (but only to the extent then 
exercisable) and had no disposition of the shares acquired upon such exercise 
been made prior to such merger, consolidation, sale, conveyance or Change in 
Control, less the Option price therefor or, in lieu thereof, the Board shall 
give the optionee at least twenty days prior written notice of any such 
transaction in order to enable the optionee to exercise the exercisable 
portion, if any, of the Option.  Upon receipt of such consideration effective 
on the date specified in such notice, all Options (whether or not then 
exercisable) shall immediately terminate and be of no further force or 
effect. The value of the stock or other securities the optionee would have 
received if the Option had been exercised shall be determined in good faith 
by the Board, and in the case of shares of Common Stock, in accordance with 
the provisions of Section 8 hereof.

              (ii) The Board shall also have the power and right to 
accelerate the exercisability of any Options, notwithstanding any limitations 
in this Plan or in the Agreement upon such merger, consolidation, sale, 
conveyance or Change in Control.

         (c)  A "Change in Control" shall be deemed to have occurred if any 
person, or any 

<PAGE>

two or more persons acting as a group, and all affiliates of such person or 
persons, who prior to such time Beneficially Owned (as defined in Rule 13d-3 
under the Exchange Act) less than 40% of the then outstanding Common Stock, 
shall acquire such additional shares of Common Stock in one or more 
transactions, or series of transactions, such that following such transaction 
or transactions, such person or group and affiliates Beneficially Own 50% or 
more of the Common Stock outstanding.

         (d)  If by reason of a corporate merger, consolidation, acquisition 
of property or stock, separation, reorganization, or liquidation, the Board 
shall authorize the issuance or assumption of a stock option or stock options 
in a transaction to which Section 424(a) of the Code applies, then, 
notwithstanding any other provision of the Plan, the Board may grant an 
option or options upon such terms and conditions as it may deem appropriate 
for the purpose of assumption of the old Option, or substitution of a new 
option for the old Option, in conformity with the provisions of such Section 
424(a) of the Code and the Regulations thereunder, and any such option shall 
not reduce the number of shares otherwise available for issuance under the 
Plan.  In the event of such issuance or assumption, the provisions of Section 
13(b) hereof shall not be applicable.

    14.  No Special Employment Rights.

         Nothing contained in the Plan or in any Option granted under the 
Plan shall confer upon any optionee any right with respect to the 
continuation of his or her employment by the Company or any subsidiary or 
interfere in any way with the right of the Company or any subsidiary, subject 
to the terms of any separate employment agreement to the contrary, at any 
time to terminate such employment or to increase or decrease the compensation 
of the Option holder from the rate in existence at the time of the grant of 
an Option.  Whether an authorized leave of absence, or absence in military or 
government service, shall constitute termination of employment for purposes 
of any Option shall be determined by the Board at the time of such occurrence.

    15.  Withholding.

         The Company's obligation to deliver shares upon the exercise of any 
Option granted under the Plan shall be subject to the Option holder's 
satisfaction of any applicable federal, state and local income and employment 
tax withholding requirements.  The Company and optionee may agree to withhold 
shares of Common Stock purchased upon exercise of an Option to satisfy the 
above-mentioned withholding requirements.

    16.  Restrictions on Exercise of Options and Issuance of Shares.

         (a)  Notwithstanding the provisions of Sections 9 and 11 hereof, an 
Option cannot be exercised, and the Company may delay the issuance of shares 
covered by the exercise of an Option and the delivery of a certificate for 
such shares, until one of the following conditions shall be satisfied:

              (i)  The shares with respect to which such Option has been 
exercised are at the time of the issuance of such shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or

<PAGE>

              (ii) Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of such shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         (b)  The Company shall be under no obligation to qualify shares or 
to cause a registration statement or a post-effective amendment to any 
registration statement to be prepared for the purpose of covering the 
issuance of shares in respect of which any Option may be exercised or to 
cause the issuance of such shares to be exempt from registration and 
qualification under applicable federal and state securities acts now in force 
or as hereinafter amended, except as otherwise agreed to by the Company in 
writing in its sole discretion.

    17.  Purchase for Investment; Rights of Holder on Subsequent Registration.

         Unless and until the shares to be issued upon exercise of an Option 
granted under the Plan have been effectively registered under the Securities 
Act of 1933, as amended (the "1933 Act"), as now in force or hereafter 
amended, the Company shall be under no obligation to issue any shares covered 
by any Option unless the person who exercises such Option, in whole or in 
part, shall give a written representation and undertaking to the Company 
which is satisfactory in form and scope to counsel for the Company and upon 
which, in the opinion of such counsel, the Company may reasonably rely, that 
he or she is acquiring the shares issued pursuant to such exercise of the 
Option for his or her own account as an investment and not with a view to, or 
for sale in connection with, the distribution of any such shares, and that he 
or she will make no transfer of the same except in compliance with any rules 
and regulations in force at the time of such transfer under the 1933 Act, or 
any other applicable law, and that if shares are issued without such 
registration, a legend to this effect may be endorsed upon the securities so 
issued.

         In the event that the Company shall, nevertheless, deem it necessary 
or desirable to register under the 1933 Act or other applicable statutes any 
shares with respect to which an Option shall have been exercised, or to 
qualify any such shares for exemption from the 1933 Act or other applicable 
statutes, then the Company may take such action and may require from each 
optionee such information in writing for use in any registration statement, 
supplementary registration statement, prospectus, preliminary prospectus, 
offering circular or any other document that is reasonably necessary for such 
purpose and may require reasonable indemnity to the Company and its officers 
and directors from such holder against all losses, claims, damages and 
liabilities arising from such use of the information so furnished and caused 
by any untrue statement of any material fact therein or caused by the 
omission to state a material fact required to be stated therein or necessary 
to make the statements therein not misleading in the light of the 
circumstances under which they were made.

    18.  Loans.

         At the discretion of the Board, the Company may loan to the 
optionee, or pay to the optionee as a bonus, some or all of the purchase 
price of the shares acquired upon exercise of an Option, the terms of such 
loans or bonus to be at the discretion of the Board.

<PAGE>

    19.  Modification of Outstanding Options.

         Subject to any applicable limitations contained herein, the Board 
may authorize the amendment of any outstanding Option with the consent of the 
optionee when and subject to such conditions as are deemed to be in the best 
interests of the Company and in accordance with the purposes of the Plan. 
Without limiting the foregoing, the Board shall have the authority to effect, 
at any time and from time to time, with the consent of the affected 
optionees, the cancellation of any or all outstanding Options under the Plan 
and to grant in substitution therefor new Options under the Plan covering the 
same or different numbers of Shares and having, at the discretion of the 
Board and subject to Sections 6 and 8 hereof, an exercise price, in the case 
of Options designated as non-qualified stock options, as shall be determined 
by the Board and, in the case of Options designated as incentive stock 
options, of not less than one hundred percent (100%) of the fair market value 
of the Common Stock on the new grant date.

    20.  Approval of Board and Stockholders.

         The Plan shall become effective upon adoption by the Board and the 
stockholders of the Company; provided, however, that the Plan shall be 
submitted for approval by the stockholders of the Company within 12 months 
after the date of adoption of the Plan by the Board.  If the stockholders of 
the Company fail to approve the Plan within 12 months after the date of 
adoption of the Plan by the Board, the Plan and all stock options granted 
thereunder shall be and become null and void and of no further force or 
effect.

    21.  Termination and Amendment of Plan.

         Unless sooner terminated as herein provided, the Plan shall 
terminate ten years from the earlier of (x) the date on which the Plan was 
duly adopted by the Board, and (y) the date on which the Plan was duly 
approved by the stockholders of the Company.  The Board may at any time 
terminate the Plan or make such modification or amendment thereof as it deems 
advisable; provided, however, (i) the Board may not, without the approval of 
the stockholders of the Company obtained in the manner stated in Section 20 
hereof, increase the maximum number of shares for which Options may be 
granted or change the designation of the class of persons eligible to receive 
Options under the Plan, and (ii) any such modification or amendment of the 
Plan shall be approved by a majority of the stockholders of the Company to 
the extent that such stockholder approval is necessary to comply with 
applicable provisions of the Code, rules promulgated pursuant to Section 16 
of the Exchange Act (if any), applicable state law, or applicable NASD or 
exchange listing requirements.  Termination or any modification or amendment 
of the Plan shall not, without the consent of an optionee, affect his or her 
rights under an Option theretofore granted to him or her.

    22.  Duties of the Company.

         The Company shall at all times keep available for issuance or 
delivery such number of shares of Common Stock as will be sufficient to 
satisfy the requirements of the Plan.

<PAGE>

    23.  Limitation of Rights in the Option Shares.

         An optionee shall not be deemed for any purpose to be a stockholder 
of the Company with respect to any of the Options until (x) the Option shall 
have been exercised with respect thereto (including payment to the Company of 
the exercise price) and (y) the earlier to occur of (i) the delivery by the 
Company to the optionee of a certificate therefor, or (ii) the date on which 
the Company is required to deliver a certificate pursuant to Section 9(b) 
hereof.

    24.  Governing Law.

         The Plan and all Options shall be governed by and construed under 
the laws of the State of Delaware, without giving effect to principles of 
conflicts of law.

    25.  Notices.

         Any communication or notice required or permitted to be given under 
the Plan shall be in writing, and mailed by registered or certified mail or 
delivered by hand, if to the Company, to the attention of the President at 
the Company's principal place of business; and, if to an optionee, to his or 
her address as it appears on the records of the Company.

    26.  Headings.

         The headings contained in this Plan are for convenience of reference 
only and in no way define, limit or describe the scope or intent of the Plan 
or in any way affect this Agreement.

                         NON-QUALIFIED STOCK OPTION AGREEMENT
                              PURSUANT TO AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    AGREEMENT made _______________, 19__, by and between AYURCORE, INC., a 
Delaware corporation with its principal place of business at 1737 N. First 
Street, Suite 290, San Jose, California 95112 (the "Company"), and the 
undersigned employee, agent or director of, or consultant to, the Company or 
any of its subsidiaries (the "Optionee").

                                 W I T N E S S E T H:

    WHEREAS, the Company considers it desirable and in its best interests 
that the Optionee be encouraged to acquire an ownership interest in the 
Company, and thereby have an added incentive to advance the interests of the 
Company, by the grant of an option to purchase shares of the Company's common 
stock, par value $.001 per share (the "Common Stock"), in accordance with the 
Company's 1997 Stock Option Plan (the "Plan") on the terms and conditions 
hereinafter set forth; and

    WHEREAS, the Plan provides that each option granted thereunder is to be 
evidenced by an option agreement, setting forth the terms and conditions of 
the option.

    NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements contained herein, the Company and the Optionee 
hereby agree as follows:

    1.   Grant of Option.

    The Company hereby grants to the Optionee the right, privilege and option 
(the "Option") to purchase that number of shares of the Company's Common 
Stock set forth on the signature page hereof (the "Shares") at the purchase 
price per Share set forth on the signature page hereof (the "Purchase 
Price"), in the manner and subject to the conditions hereinafter provided and 
contained in the Plan.  In the event of any inconsistencies between the Plan 
and this Agreement, the Plan shall govern.  Such number of Shares issuable 
upon exercise of the Option shall be subject to adjustment as provided in 
Section 7 below.  The Option is not intended to be an incentive stock option 
meeting the requirements of Section 422 of the Internal Revenue Code of 1986, 
as amended (the "Code").

    2.   Time of Exercise of Option.

    Subject to the provisions of Section 4 below, the Option shall vest and 
become exercisable in accordance with the schedule set forth on the signature 
page hereof; provided, however, that upon a Change in Control (as defined in 
the Plan) of the Company, the Option shall be immediately exercisable.  To 
the extent the Option is not exercised by the Optionee when it becomes 
exercisable, it shall continue in full force and effect until the Expiration 
Date (as hereinafter defined).

<PAGE>

    3.   Method of Exercise.

    The Option shall be exercised by written notice in the form of Exhibit A 
hereto directed to the Company at the Company's address set forth above, duly 
executed by the Optionee, specifying the number of shares being purchased and 
accompanied by either (i) cash or check payable to the order of the Company 
in full payment of the Purchase Price for the number of Shares being 
purchased, or (ii) certificate(s), duly endorsed for transfer to the Company 
with signature guaranteed, for that number of previously acquired Shares 
having an aggregate fair market value as determined in accordance with the 
Plan ("Fair Market Value"), on the date of exercise equal to the full 
Purchase Price for the number of Shares being purchased, or (iii) a 
combination of (i) and (ii).

    The Option shall not be exercisable at any time in an amount less than 
100 Shares (or the remaining fraction of a Share then covered by and 
purchasable under the Option if less than 100 Shares).

    4.   Term of Options; Exercisability.

         A.   Term.

              1.   This Option shall expire on the date set forth on the 
signature page hereto (the "Expiration Date"), subject to earlier termination 
as herein provided.

              2.   Except as otherwise provided in this Section 4, if the 
Optionee's employment by, or retention as an agent, director of, or 
consultant to, the Company and its subsidiaries is terminated for any reason, 
the Option shall terminate on the earlier of (i) three months after the date 
the Optionee's employment by or retention as an agent, director of, or 
consultant to, the Company and its subsidiaries is terminated, or (ii) the 
date on which the Option expires by its terms.

              3.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries for cause (as such term is defined in any employment 
agreement or similar agreement between the Optionee and the Company or, if 
there is no such employment or similar agreement, or the employment or 
similar agreement does not have provisions relating to termination for cause, 
as such term is defined by the law of the State of New York), the Option will 
to the extent not terminated be deemed to have terminated on the date 
immediately preceding the date the Optionee's employment by, or retention as 
an agent, director of, or consultant to, the Company is terminated by the 
Company and its subsidiaries.

              4.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries because the Optionee has become disabled (within the meaning 
of Section 22(e)(3) of the Code), the Option shall terminate on the earlier 
of (i) one year after the date the Optionee's employment by, or retention as 

                                         2
<PAGE>

an agent, director of, or consultant to, the Company and its subsidiaries is 
terminated, or (ii) the date on which the Option expires by its terms.

              5.   In the event of the death of the Optionee, the Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         B.   Exercisability.

              1.   Except as provided in this Section 4.B., if the Optionee's 
employment by, or retention as an agent, director of, or consultant to, the 
Company and its subsidiaries is terminated, the Option shall be exercisable 
only to the extent that the right to purchase Shares under the Option is 
exercisable on the date the Optionee's employment by, or retention as an 
agent, director of, or consultant to, the Company and its subsidiaries is 
terminated.

              2.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries because the Optionee has become disabled (as such term is 
defined in any employment or similar agreement between the Optionee and the 
Company or, if there is no such employment or similar agreement, or the 
employment or similar agreement does not contain provisions relating to 
termination for disability, as determined by the Board of Directors of the 
Company), the Option shall be immediately exercisable as to the full number 
of Shares covered by the Option, whether or not under the provisions of 
Section 2 hereof the Option was otherwise exercisable as of the date of 
disability.

              3.   In the event of the death of the Optionee, the Option 
granted to the Optionee shall be immediately exercisable as to the full 
number of Shares covered thereby, whether or not under the provisions of 
Section 2 hereof the Optionee was entitled to do so at the date of his death, 
by the executor, administrator or personal representative of the Optionee, or 
by any person or persons who acquired the right to exercise such Option by 
bequest or inheritance or by reason of the death of the Optionee.

    5.   Non-Transferability.

    [This provision may be deleted or modified at the discretion of the Board 
or Committee granting the Option].

    The right of the Optionee to exercise the Option shall not be assignable 
or transferable by the Optionee otherwise than by will or the laws of descent 
and distribution, and the Option may be exercised during the lifetime of the 
Optionee only by the Optionee.  The Option shall be null and void and without 
effect upon the bankruptcy of the Optionee or upon any attempted assignment 
or transfer, except as hereinabove provided, including without limitation, 
any purported assignment, whether voluntary or by operation of law, pledge, 
hypothecation or other disposition contrary to the 

                                         3
<PAGE>

provisions hereof, or levy of execution, attachment, trustee process or 
similar process, whether legal or equitable, upon the Option.

    6.   Representation Letter and Investment Legend.

         A.   Notwithstanding the provisions of Sections 3 and 4 hereof, the 
Option cannot be exercised, and the Company may delay the issuance of the 
Shares covered by the exercise of the Option and the delivery of a 
certificate for the Shares, until one of the following conditions shall be 
satisfied:

              1.   The Shares with respect to which the Option has been 
exercised are at the time of the issuance of the Shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or 

              2.   Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of the Shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         B.   In the event that for any reason the Shares to be issued upon 
exercise of the Option shall not be effectively registered under the 
Securities Act of 1933, as amended (the "1933 Act"), upon any date on which 
the Option is exercised in whole or in part, the Optionee shall give a 
written representation to the Company in the form attached hereto as Exhibit 
A and the Company shall place an "investment legend," so-called, as described 
in Exhibit A, upon any certificate for the Shares issued by reason of such 
exercise.  In the event that the Company shall, nevertheless, deem it 
necessary or desirable to register under the 1933 Act or other applicable 
statutes the Shares with respect to which the Option shall have been 
exercised, or to qualify the Shares for exemption from the 1933 Act or other 
applicable statutes, then the Company may take such action and may require 
from the Optionee such information in writing for use in any registration 
statement, supplementary registration statement, prospectus, preliminary 
prospectus, offering circular or any other document that is reasonably 
necessary for such purpose and may require reasonable indemnity to the 
Company and its officers and directors from the Optionee against all losses, 
claims, damages and liabilities arising from such use of the information so 
furnished and caused by any untrue statement of any material fact therein or 
caused by the omission to state a material fact required to be stated therein 
or necessary to make the statements therein not misleading in the light of 
the circumstances under which they were made.

         C.   The Company shall be under no obligation to qualify the Shares 
or to cause a registration statement or a post-effective amendment to any 
registration statement to be prepared for the purposes of covering the issue 
of the Shares or to cause the issuance of the Shares to be exempt from 
registration and qualification under applicable federal and state securities 
acts now in force or as hereinafter amended, except as otherwise agreed to by 
the Company in writing in its sole discretion and, accordingly, the Company 
may delay the issuance of the Shares covered by the 

                                         4
<PAGE>

exercise of the Option and the delivery of a certificate for the Shares until 
the Company shall have determined that all conditions to the issuance of the 
Shares shall have been satisfied.

    7.   Adjustment in and Changes in Common Stock.

    Subject to the Plan, if the outstanding shares of the Common Stock are 
changed into or exchanged for a different number or kind of shares or other 
securities of the Company by reason of any reorganization, recapitalization, 
reclassification, stock split, combination of shares, or dividends payable in 
capital stock, appropriate and equitable adjustment shall be made by the 
Board of Directors of the Company, in its sole discretion, in the number and 
kind of shares as to which the Option or portion thereof then unexercised 
shall be exercisable.  Such adjustment in the Option shall be made without 
change in the total price applicable to the unexercised portion of such the 
Option and with a corresponding adjustment in the Option price per share.

    8.   Effect on Other Rights.

    This Agreement shall in no way affect the Optionee's participation in or 
benefits under any other plan or benefit program maintained or provided by 
the Company.  Nothing in this Agreement shall be construed to give the 
Optionee any right to any additional options other than in the sole 
discretion of the Board of Directors of the Company or to confer on the 
Optionee any right to continue in the employ of the Company or any subsidiary 
thereof or to continue to be retained as an agent, director of, or consultant 
to, the Company, or to be evidence of any agreement or understanding, express 
or implied, that the Company will employ or continue to retain the Optionee 
in any particular position or at any particular rate of remuneration, or for 
any particular period of time or to interfere in any way with the right of 
the Company or a subsidiary thereof (or the right of the Optionee) to 
terminate the employment or retention of the Optionee at any time, with or 
without cause, notwithstanding the possibility that the Option may thereby be 
terminated entirely.

    9.   Rights as a Shareholder.

    The Optionee shall have no rights as a shareholder with respect to any 
Shares which may be purchased by exercise of the Option until (x) the Option 
shall have been exercised with respect thereto (including payment to the 
Company of the Purchase Price), and (y) the earlier to occur of (i) delivery 
by the Company to the optionee of a certificate therefor or (ii) the date on 
which the Company is required to deliver a certificate pursuant to the Plan 
and this Agreement.  Except as otherwise expressly provided in the Plan, no 
adjustment shall be made for dividends or other rights for which the record 
date is prior to the date such certificate is issued or required to be issued 
in accordance with the Plan.

    10.  Governing Law.

    THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE 
APPLICABLE TO CONTRACTS TO BE MADE AND PERFORMED ENTIRELY 

                                         5
<PAGE>


THEREIN WITHOUT REFERENCE TO CONFLICT OF LAWS PRINCIPLES.

    11.  Withholding Taxes.

    Whenever Shares are to be issued upon exercise of the Option, the Company 
shall have the right to require the Optionee to remit to the Company an 
amount sufficient to satisfy all federal, state and local withholding tax 
requirements, if any, prior to the delivery of any certificate or 
certificates for such Shares.  The Company may agree to permit the Optionee 
to withhold Shares purchased upon exercise of this Option to satisfy the 
above-mentioned withholding requirement.

    12.  Headings.

    The headings contained in this Agreement are for convenience of reference 
only and in no way define, limit or describe the scope or intent of this 
Agreement or in any way affect this Agreement.

    13.  Binding Effect.

    This Agreement shall inure to the benefit of and be binding upon the 
parties hereto and their respective heirs, executors, administrators, 
successors and assigns.

                                         6

    IN WITNESS WHEREOF, the Company has caused this Agreement to be executed, 
and the Optionee has hereunto set his or her hand and seal, all as of the day 
and year first above written.

                              TO STOCK OPTION AGREEMENT





                                  Date:______________________

AyurCore, Inc.
1737 N. First Street, Suite 290
San Jose, California 95112

Ladies and Gentlemen:

    I hereby elect to purchase ____ shares of the Common Stock, $.001 par 
value per share, of AyurCore, Inc. (the "Company") under the option granted 
to me pursuant to the Stock Option Agreement, dated _______________, ____, 
under the Company's 1997 Stock Option Plan.

    Enclosed is [cash] [a check] in the amount of $______.___ [______ 
shares of the Company's Common Stock] in full payment of the shares being 
purchased ($________ per share x ____ shares).



    Please deliver certificates representing the shares being purchased to me 
at:

              _____________________________

              _____________________________

              _____________________________

    I hereby acknowledge that I have been informed as follows:

         1.   The shares of common stock of the Company to be issued to me 
pursuant to the exercise of said option have not been registered under the 
Securities Act of 1933, as amended (the "1933 Act"), and accordingly, must be 
held indefinitely unless such shares are subsequently registered under the 
1933 Act, or an exemption from such registration is available.

    2.   Routine sales of securities made in reliance upon Rule 144, if 
applicable, under the 1933 Act can be made only after the holding period and 
in limited amounts in accordance with the terms and conditions provided by 
that Rule, and in any sale to which that Rule is not applicable, registration 
or compliance with some other exemption under the 1933 Act will be required.

<PAGE>

    3.   The Company is under no obligation to me to register the shares or 
to comply with any such exemptions under the 1933 Act.

    4.   The availability of Rule 144, if applicable, is dependent upon 
adequate current public information with respect to the Company being 
available and, at the time that I may desire to make a sale pursuant to the 
Rule, the Company may neither wish nor be able to comply with such 
requirement.

    In consideration of the issuance of certificates for the shares to me, I 
hereby represent and warrant that I am acquiring such shares for my own 
account for investment, and that I will not sell, pledge, transfer or 
otherwise dispose of such shares in the absence of an effective registration 
statement covering the same, except as permitted by the provisions of Rule 
144, if applicable, or some other applicable exemption under the 1933 Act.  
In view of this representation and warranty, I agree that there may be 
affixed to the certificates for the shares to be issued to me, and to all 
certificates issued hereafter representing such shares (until in the opinion 
of counsel, which opinion must be reasonably satisfactory in form and 
substance to counsel for the Company, it is no longer necessary or required) 
a legend as follows:

    "The shares of common stock represented by this certificate have not
    been registered under the Securities Act of 1933, as amended (the
    "Act"), and were acquired by the registered holder, pursuant to a
    representation and warranty that such holder was acquiring such shares
    for his or her own account and for investment, with no intention to
    transfer or dispose of the same, in violation of the registration
    requirements of the Act.  These shares may not be sold, pledged,
    transferred or otherwise disposed of in the absence of an effective
    registration statement under the Act, or an opinion of counsel, which
    opinion is reasonably satisfactory to counsel to the Company, to the
    effect that registration is not required under the Act."

    I further agree that the Company may place a stop order with its Transfer 
Agent, prohibiting the transfer of such shares, so long as the legend remains 
on the certificates representing the shares.

                                  Very truly yours,


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

                           INCENTIVE STOCK OPTION AGREEMENT
                              PURSUANT TO AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    AGREEMENT made as of ____________ ___, 19__, by and between AYURCORE, 
INC., a Delaware corporation with its principal place of business at 1737 N. 
First Street, Suite 290, San Jose, California 95112 (the "Company"), and the 
undersigned employee of the Company or any of its subsidiaries (the 
"Optionee").

                                 W I T N E S S E T H:

    WHEREAS, the Company considers it desirable and in its best interests 
that the Optionee be encouraged to acquire an ownership interest in the 
Company, and thereby have an added incentive to advance the interests of the 
Company, by the grant of an option to purchase shares of the Company's common 
stock, par value $.001  per share (the "Common Stock"), in accordance with 
the Company's 1997 Stock Option Plan (the "Plan") on the terms and conditions 
hereinafter set forth; and

    WHEREAS, the Plan provides that each option granted thereunder is to be 
evidenced by an option agreement, setting forth the terms and conditions of 
the option.

    NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements contained herein, the Company and the Optionee 
hereby agree as follows:

    1.   Grant of Option.

    The Company hereby grants to the Optionee the right, privilege and option 
(the "Option") to purchase that number of shares of the Company's Common 
Stock set forth on the signature page hereto (the "Shares") at the purchase 
price per Share set forth on the signature page hereto (the "Purchase 
Price"), in the manner and subject to the conditions hereinafter provided and 
contained in the Plan.  In the event of any inconsistencies between the Plan 
and this Agreement, the Plan shall govern.  Such number of Shares issuable 
upon exercise of the Option shall be subject to adjustment as provided in 
Section 7 below.  The Option is intended to be an incentive stock option 
meeting the requirements of Section 422 of the Internal Revenue Code of 1986, 
as amended (the "Code").  If for any reason the Option or any part hereof is 
not deemed to be an incentive stock option, to the extent it is not an 
incentive stock option, it shall be treated as a non-qualified stock option.

    2.   Time of Exercise of Option.

    Subject to the provisions of Section 4 below, the Option shall vest and 
become exercisable in accordance with the schedule set forth on the signature 
page hereof; provided, however, that upon 

<PAGE>

a Change in Control (as defined in the Plan) of the Company, the Option shall 
be immediately exercisable.  To the extent the Option is not exercised by the 
Optionee when it becomes exercisable, it shall continue in full force and 
effect until the Expiration Date (as hereinafter defined).

    3.   Method of Exercise.

    The Option shall be exercised by written notice in the form of Exhibit A 
hereto, directed to the Company at the Company's address set forth above, 
duly executed by the Optionee, specifying the number of shares being 
purchased and accompanied by either (i) cash or check payable to the order of 
the Company in full payment of the Purchase Price for the number of Shares 
being purchased, or (ii) certificate(s), duly endorsed for transfer to the 
Company with signature guaranteed, for that number of previously acquired 
Shares having an aggregate fair market value as determined in accordance with 
the Plan ("Fair Market Value"), on the date of exercise equal to the full 
Purchase Price for the number of Shares being purchased, or (iii) a 
combination of (i) and (ii).

    The Option shall not be exercisable at any time in an amount less than 100
Shares (or the remaining Shares then covered by and purchasable under the Option
if less than 100 Share).

    4.   Term of Options; Exercisability.

         A.   Term.

              1.   This Option shall expire on the tenth anniversary of the 
date of this agreement (the "Expiration Date"), subject to earlier 
termination as herein provided.

              2.   Except as otherwise provided in this Section 4, if the 
Optionee's employment by the Company and its subsidiaries is terminated for 
any reason, the Option shall terminate on the earlier of (i) three months 
after the date the Optionee's employment by the Company and its subsidiaries 
is terminated, or (ii) the date on which the Option expires by its terms.

              3.   If the Optionee's employment is terminated by the Company 
and its subsidiaries for cause (as such term is defined in any employment 
agreement or similar agreement between the Optionee and the Company or, if 
there is no such employment agreement, or the employment agreement does not 
have provisions relating to termination for cause, as such term is defined by 
the law of the State of Delaware), the Option will to the extent not 
terminated be deemed to have terminated on the date immediately preceding the 
date the Optionee's employment is terminated by the Company and its 
subsidiaries.

              4.   If the Optionee's employment is terminated by the Company 
and its subsidiaries because the Optionee has become disabled (as defined in 
any employment agreement or similar agreement between the Optionee and the 
Company or within the meaning of Section 22(e)(3) of the Code), the Option 
shall terminate on the earlier of (i) one year after the date the Optionee's

                                         2
<PAGE>

employment by the Company and its subsidiaries is terminated, or (ii) the 
date on which the Option expires by its terms.

              5.   In the event of the death of the Optionee, the Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         B.   Exercisability.

              1.   Except as provided in this Section 4.B., if the Optionee's 
employment by the Company and its subsidiaries is terminated, the Option 
shall be exercisable only to the extent that the right to purchase Shares 
under the Option is exercisable on the date the Optionee's employment by the 
Company and its subsidiaries is terminated.

              2.   If the Optionee's employment is terminated by the Company 
and its subsidiaries because the Optionee has become disabled (as such term 
is defined in any employment agreement between the Optionee and the Company 
or, if there is no such employment agreement, or the employment agreement 
does not contain provisions relating to termination for disability, as 
determined by the Board of Directors of the Company), the Option shall be 
immediately exercisable as to the full number of Shares covered by the 
Option, whether or not under the provisions of Section 2 hereof the Option 
was otherwise exercisable as of the date of disability.

              3.   In the event of the death of the Optionee, the Option 
granted to the Optionee shall be immediately exercisable as to the full 
number of Shares covered thereby, whether or not under the provisions of 
Section 2 hereof the Optionee was entitled to do so at the date of his death, 
by the executor, administrator or personal representative of the Optionee, or 
by any person or persons who acquired the right to exercise such Option by 
bequest or inheritance or by reason of the death of the Optionee.

    5.   Non-Transferability.

    The right of the Optionee to exercise the Option shall not be assignable 
or transferable by the Optionee otherwise than by will or the laws of descent 
and distribution, and the Option may be exercised during the lifetime of the 
Optionee only by the Optionee.  The Option shall be null and void and without 
effect upon the bankruptcy of the Optionee or upon any attempted assignment 
or transfer, except as hereinabove provided, including without limitation, 
any purported assignment, whether voluntary or by operation of law, pledge, 
hypothecation or other disposition contrary to the provisions hereof, or levy 
of execution, attachment, trustee process or similar process, whether legal 
or equitable, upon the Option.

<PAGE>

         A.   Notwithstanding the provisions of Sections 3 and 4 hereof, the 
Option cannot be exercised, and the Company may delay the issuance of the 
Shares covered by the exercise of the Option and the delivery of a 
certificate for the Shares, until one of the following conditions shall be 
satisfied:

              1.   The Shares with respect to which the Option has been 
exercised are at the time of the issuance of the Shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or 

              2.   Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of the Shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         B.   In the event that for any reason the Shares to be issued upon 
exercise of the Option shall not be effectively registered under the 
Securities Act of 1933, as amended (the "1933 Act"), upon any date on which 
the Option is exercised in whole or in part, the Optionee shall give a 
written representation to the Company in the form attached hereto as Exhibit 
A and the Company shall place an "investment legend," so-called, as described 
in Exhibit A, upon any certificate for the Shares issued by reason of such 
exercise.  In the event that the Company shall, nevertheless, deem it 
necessary or desirable to register under the 1933 Act or other applicable 
statutes the Shares with respect to which the Option shall have been 
exercised, or to qualify the Shares for exemption from the 1933 Act or other 
applicable statutes, then the Company may take such action and may require 
from the Optionee such information in writing for use in any registration 
statement, supplementary registration statement, prospectus, preliminary 
prospectus, offering circular or any other document that is reasonably 
necessary for such purpose and may require reasonable indemnity to the 
Company and its officers and directors from the Optionee against all losses, 
claims, damages and liabilities arising from such use of the information so

AyurCore, Inc.
1737 N. First Street, Suite 290

Ladies and Gentlemen:

    I hereby elect to purchase ____ shares of the Common Stock, no par value 
per share, of AyurCore, Inc. (the "Company") under the option granted to me 
pursuant to the Incentive Stock Option Agreement, dated as of 
_______________, 199_, under the Company's 1997 Stock Option Plan.

    Enclosed is [cash] [a check] in the amount of $______.___  
[______ shares of the Company's Common Stock] in full payment of the shares 
being purchased ($_______________ per share x ____ shares).



    Please deliver certificates representing the shares being purchased to me 
at:

              _____________________________

              _____________________________

              _____________________________

    I hereby acknowledge that I have been informed as follows:

         1.   The shares of common stock of the Company to be issued to me 
pursuant to the exercise of said option have not been registered under the 
Securities Act of 1933, as amended (the "1933 Act"), and accordingly, must be 
held indefinitely unless such shares are subsequently registered under the 
1933 Act, or an exemption from such registration is available.

    2.   Routine sales of securities made in reliance upon Rule 144, if 
applicable, under the 1933 Act can be made only after the holding period and 
in limited amounts in accordance with the 

                                         7
<PAGE>

terms and conditions provided by that Rule, and in any sale to which that 
Rule is not applicable, registration or compliance with some other exemption 
under the 1933 Act will be required.

    3.   The Company is under no obligation to me to register the shares or 
to comply with any such exemptions under the 1933 Act.

    4.   The availability of Rule 144, if applicable, is dependent upon 
adequate current public information with respect to the Company being 
available and, at the time that I may desire to make a sale pursuant to the 
Rule, the Company may neither wish nor be able to comply with such 
requirement.

    In consideration of the issuance of certificates for the shares to me, I 
hereby represent and warrant that I am acquiring such shares for my own 
account for investment, and that I will not sell, pledge, transfer or 
otherwise dispose of such shares in the absence of an effective registration 
statement covering the same, except as permitted by the provisions of Rule 
144, if applicable, or some other applicable exemption under the 1933 Act.  
In view of this representation and warranty, I agree that there may be 
affixed to the certificates for the shares to be issued to me, and to all 
certificates issued hereafter representing such shares (until in the opinion 
of counsel, which opinion must be reasonably satisfactory in form and 
substance to counsel for the Company, it is no longer necessary or required) 
a legend as follows:

    "The shares of common stock represented by this certificate have not
    been registered under the Securities Act of 1933, as amended (the
    "Act"), and were acquired by the registered holder, pursuant to a
    representation and warranty that such holder was acquiring such shares
    for his or her own account and for investment, with no intention to
    transfer or dispose of the same, in violation of the registration
    requirements of the Act.  These shares may not be sold, pledged,
    transferred or otherwise disposed of in the absence of an effective
    registration statement under the Act, or an opinion of counsel, which
    opinion is reasonably satisfactory to counsel to the Company, to the
    effect that registration is not required under the Act."

    I further agree that the Company may place a stop order with its Transfer
Agent, prohibiting the transfer of such shares, so long as the legend remains
on the certificates representing the shares.

                                  Very truly yours,


                                  ______________________________

                                OFFICE BUILDING LEASE
                                           
    THIS LEASE is made as of September 8, 1995 by and between Northwestern

and marked Exhibit A, the Premises being agreed, for the purposes of this 
Lease, to have an area of approximately 2,006 rentable square feet (1,791 
usable square feet) and being situated on the 2nd floor of that certain 
office building located at 1737 North First Street, San Jose, California

    The parties hereto agree that said letting and hiring is upon and subject 
to the terms, covenants and conditions herein set forth. Tenant covenants, as 
a material part of the consideration for this Lease to keep and perform each 
and all of said terms, covenants and conditions for which Tenant is liable 
and that this Lease is made upon the condition of such performance.

    Prior to the commencing of the term of this Lease the Premises shall be 
improved by the Tenant Improvements described in the Work Letter marked 
Exhibit B attached hereto.

                                       1. TERM
                                           
    The term of this Lease shall be for thirty-six (36) months. commencing 
October 15, 1995, and ending on the last day of the month immediately 
preceding the month in which the anniversary of the commencement date occurs, 
unless such term shall be sooner terminated as hereinafter provided.

Failure to enter into such an amendment, however, shall not affect Tenant's 
liability hereunder for the term of the Lease. Reference in this Lease to a 
"Lease Year" shall mean each successive twelve month period commencing with 
the commencement date.

                                    2. POSSESSION
                                           
    Tenant agrees that, if Landlord is unable to deliver possession of the 
Premises to Tenant on the scheduled commencement of the term of this Lease, 
this Lease shall not be void or voidable, nor shall Landlord be liable to 
Tenant for any loss or damage resulting therefrom, but in such event the term 
of this Lease shall not commence until  Landlord tenders possession of the 
Premises to Tenant with the Tenant Improvements substantially completed.  If 
Landlord is unable to deliver possession of the Premises by January 15, 

<PAGE>

improvements, Tenant shall be relieve from its obligations hereunder and this 
Lease shall be deemed void.

                                    3. BASIC RENT
                                           
    (a) Tenant agrees to pay Landlord Basic Rent for the Premises (subject to 
adjustments as hereinafter provided) as follows:

                   Months of Term           Monthly Basic Rent
                   --------------           ------------------
                   01 - 36                       $3,189.54

The Basic Rent shall be paid monthly, in advance on the first (1st) day of 
each calendar month during the term, except that the first month's rent shall 
be paid on execution hereof. If Tenant's obligation to pay rent commences or 
ends on a day other than the first day of a calendar month, then the rental 
for such period shall be prorated in the proportion that the number of days 
this Lease is in effect during such period bears to thirty. In addition to 
the Basic Rent, Tenant agrees to pay as additional rental the amount of 
rental adjustments and other charges required by this Lease. All rental shall 
be paid to Landlord, without prior demand and without any deduction or 
offset, in lawful money of the United States of America, at the address of 
Landlord designated on the signature page of this Lease or to such other 
person or at such other place as Landlord may from time to time designate in 
writing.

    (b) In the event Tenant fails to pay any installment of rent when due or 
in the event Tenant fails to make any other payment of which Tenant is 
obligated under this Lease when due, then Tenant shall pay to Landlord a late 
charge equal to five percent (5%) monthly to compensate Landlord for the 
extra costs incurred as a result of such late payment.  Tenant shall incur 
late charges for any payments that are received more than five (5) day after 
the due date.

                                 4. RENTAL ADJUSTMENT
                                           
    (a) For the purpose of this Article 4, the following terms are defined as 
follows:

          (i) Tenant's Percentage. That portion of the Building occupied by 
Tenant divided by the total square footage of the Building, which result is 
the following 2.43%.

         (ii) Direct Expenses Base. The amount of the annual Direct Expenses 
which Landlord has included in Basic Rent, which amount is equal to the 1996 
actual direct  expenses.

         (iii) Direct Expenses. The term "Direct Expenses" shall include:

              (A) All real and personal property taxes and assessments 
imposed by any governmental authority or agency on the Building and the land 
on which the

<PAGE>

Building is located (including a pro rata portion of any taxes levied on any 
common areas); any assessments levied in lieu of taxes; any nonprogressive 
tax on or measured by gross rentals received from the rental of space in the 
Building; and any other costs levied or assessed by, or at the direction of, 
any federal, state, or local government authority in connection with the use 
or occupancy of the Premises or the parking facilities serving the Premises; 
any tax on this transaction or any document to which Tenant is a party 
creating or transferring an interest in the Premises, and any expenses, 
including cost of attorneys or experts, reasonably incurred by Landlord in 
seeking reduction by the taxing authority of the above referenced taxes, less 
tax refunds obtained as a result of an application for review thereof; but 
shall no include any net income, franchise, capital stock, estate or 
inheritance taxes.

              (B) Operating costs consisting of costs incurred by Landlord in 
maintaining and operating the Building, exclusive of costs required to be 
capitalized for federal income tax purposes, and including (without limiting 
the generality of the foregoing) the following: costs of utilities, supplies 
and insurance, costs of services of independent contractors, managers and 
other suppliers, the fair rental value of the Building office, costs of 
compensation (including employment taxes and fringe benefits) of all persons 
who perform regular and recurring duties connected with the management, 
operation, maintenance, and repair of the Building, its equipment, parking 
facilities and the common areas, including, without limitation, engineers, 
janitors, foremen, floor waxers, window washers, watchmen and gardeners, but 
excluding person performing services not uniformly available to or performed 
for substantially all Building tenants; a reasonable management fee; cost of 
maintaining, repairing and replacing landscaping, sprinkler systems, concrete 
walkways, paved parking areas, signs, and site lighting.

              (C) Amortization of such capital improvements as Landlord may 
have installed: (a) for the purpose of reducing operating costs, (b) to 
comply with governmental rules and regulations promulgated after completion 
of the Building, (c) for the purpose of replacing existing capital items and 
improvements, and (d) any costs required by the CC&R's, as defined in Article 
6, affecting the Premises or by any corporation, committee or association 
formed in connection therewith, provided that such cost together with  
interest at the maximum rate allowed by law shall be amortized over such 
reasonable period as Landlord shall determine, and only the monthly amortized 
cost shall be included in Direct Expenses.

    (b) If Tenant's Percentage of the Direct Expenses paid or incurred by 
Landlord for any calendar year exceeds the Direct Expenses Base included in 
Tenant's rent, then Tenant shall pay such excess as additional rent. In 
addition, for each year after the first calendar year, or portion thereof, 
Tenant shall pay Tenant's Percentage of Landlord's estimate of the amount by 
which Direct Expenses for that year shall exceed the Direct Expenses Base 
("Landlord Estimate"). This estimated amount shall be divided into twelve 
equal monthly installments. Tenant shall pay to Landlord, concurrently with 
the regular monthly rent payment next due following the receipt of such 
statement, an amount equal to one monthly installment multiplied by the 
number of months from January in the calendar year 

<PAGE>

in which said statement is submitted to the month of such payment, both 
months inclusive. Subsequent installments shall be payable concurrently with 
the regular monthly rent payments for the balance of that calendar year and 
shall continue until the next calendar year's statement is rendered. As soon 
as possible after the end of each calendar year, Landlord shall provide 
Tenant with a statement showing the amount of Tenant's Percentage of Direct 
Expenses, the amount of Landlord's Estimate actually paid by Tenant and the 
amount of the Direct Expenses Base. Thereafter, Landlord shall reconcile the 
above amounts and shall either bill Tenant for the balance due (payable on 
demand by Landlord) or credit any overpayment by Tenant towards the next 
monthly installment of Landlord's Estimate falling due, as the case may be. 
For purposes of making these calculations, in no event shall Tenant's 
Percentage of the Direct Expenses be deemed to be less than the Direct 
Expenses Base.

    (c) Even though the term has expired and Tenant has vacated the Premises, 
when the final determination is made of Tenant's Percentage of Direct 
Expenses for the year in which this Lease terminates, Tenant shall 
immediately pay any increase due over the estimated expenses paid and, 
conversely, any overpayment made in the event said expenses decrease shall be 
rebated by Landlord to Tenant.

                                 5. SECURITY DEPOSIT
                                           
    Tenant has deposited with Landlord the sum of Thirteen Thousand One 
Hundred Eighty Nine Dollars and 54/l00ths ($13,189.54). Said sum shall be 
held by Landlord as security for the faithful performance by Tenant of all of 
Tenant's obligations hereunder. Ten Thousand Dollars ($10,000.00) of the 
deposit set forth above shall be held in an interest bearing account.  All 
interest earned from said $10,000.00 shall be paid to Tenant by Landlord at 
the end of the lease term.  If Tenant defaults with respect to any provision 
of this Lease, including but not limited to the provisions relating to the 
payment of rent, Landlord may (but shall not be required to) use, apply or 
retain all or any part of this security deposit for the payment of any rent 
or any other sum in default, or for the payment of any other amount which 
Landlord may spend or become obligated to spend by reason of Tenant's default 
or to compensate Landlord for any other loss or damage which Landlord may 
suffer by reason of Tenant's default. If any portion of the deposit is so 
used or applied, Tenant shall, upon demand, deposit cash with Landlord in an 
amount sufficient to restore the security deposit to its original amount. 
Tenant's failure to do so shall be a material breach of this Lease. Landlord 
shall not be required to keep this security deposit separate from its general 
f unds, and Tenant shall not be entitled to interest on such deposit, except 
for as provided above.  If Tenant shall fully and faithfully perform all of 
its obligations under this Lease, the security deposit or any balance thereof 
shall be returned to Tenant (or, at Landlord's option, to the last assignee 
of Tenant's interest hereunder) at the expiration of the Lease term, provided 
that Landlord may retain the security deposit until such time as any amount 
due from Tenant in accordance with Article 4 hereof has been determined and 
paid in full.

                                        6. USE


<PAGE>

                                           
    (a) Tenant shall use the Premises for general office purposes and shall 
not use or permit the Premises to be used for any other purpose without the 
prior written consent of Landlord. Nothing contained herein shall be deemed 
to give Tenant any exclusive right to such use in the Building. Tenant shall 
not use or occupy the Premises in violation of law or the certificate of 
occupancy issued for the Building, and shall, upon written notice from 
Landlord, discontinue any use of the Premises which is declared by any 
governmental authority having jurisdiction to be a violation of law or of the 
certificate of occupancy. Tenant shall comply with any direction of any 
governmental authority having jurisdiction which shall, by reason of the 
nature of Tenant's use or occupancy of the Premises, impose a duty upon 
Tenant or Landlord with respect to the Premises or with respect to the use or 
occupation thereof. Tenant shall not do or permit to be done anything which 
will invalidate or increase the cost of any fire, extended coverage or any 
other insurance policy covering the Building and/or property located therein 
and shall comply with all rules, orders, regulations and requirements of the 
Insurance Service Offices, formerly known as the Pacific Fire Rating Bureau 
or any other organization performing a similar function. Tenant shall 
promptly, upon demand, reimburse Landlord for any additional premium charged 
for such policy by reason of Tenant's failure to comply with the provisions 
of this article. Tenant shall not  do or permit anything to be done in or 
about the Premises which will in any way obstruct or interfere with the 
rights of other tenants of the Building, or injure or annoy them, or use or 
allow the Premises to be used for any improper, immoral, unlawful or 
objectional purpose, nor shall Tenant cause, maintain or permit any nuisances 
in, on or about the Premises. Tenant shall not commit or suffer to be 
committed any waste in or upon the Premises.

                                      7. NOTICES
                                           
    Any notice required or permitted hereunder must be in writing and may be 
given by personal delivery, overnight courier service, or by mail, and if 
given by mail shall be deemed sufficiently given if sent by registered or 
certified mail addressed to Tenant at the Premises, or to Landlord at its 
address set forth at the end of this Lease. Either party may specify a 
different address for notice purposes by written notice to the other except 
that the Landlord may in any event use the Premises as Tenant's address for 
notice purposes.

                                      8. BROKERS
                                           
    Tenant warrants that it has had no dealings with any real estate broker 
or agent in connection with the negotiation of the Lease, except Duffy 
D'Angelo of Colliers Parrish International whose commission shall be payable 
by Landlord, and that it knows of no other real estate broker or agent who is 
or might be entitled to a commission in connection with this Lease. If Tenant 
has dealt with any other person or real estate broker with respect to leasing 
or renting space in the Building, Tenant shall be solely responsible for the 
payment of any fee due said person or firm and Tenant shall hold Landlord 
free and harmless against any liability in respect thereto, including 
attorneys' fees and costs.

                                   9. HOLDING OVER
                                           
    If Tenant holds over after the expiration or earlier termination of the 
term hereof without the express written consent of Landlord, Tenant shall 
become a Tenant at sufferance only, at a rental rate equal to one hundred 
fifty percent (150%) of the rent in effect upon the date of such expiration 
(subject to adjustment as provided in paragraph 4 hereof and prorated on a 
daily basis), and otherwise subject to the terms, covenants and conditions 
herein specified, so far as applicable. Acceptance by Landlord of rent after 
such expiration or earlier termination shall not result in a renewal of this 
Lease. The foregoing provisions of this Article 9 are in addition to and do 
not affect Landlord's right of reentry or any rights of Landlord hereunder or 
as otherwise provided by law. If Tenant fails to surrender the Premises upon 
the expiration of this Lease despite demand to  do so by Landlord, Tenant 
shall indemnify and hold Landlord harmless from all loss or liability, 
including without limitation, any claim made by any succeeding tenant founded 
on or resulting from such failure to surrender, and any attorneys' fees and 
costs.

                            10. TAXES ON TENANT'S PROPERTY
                                           
    (a) Tenant shall be liable for and shall pay, at least ten days before 
delinquency, all taxes levied against any personal property or trade fixtures 
placed by Tenant in or about the Premises. If any such taxes on Tenant's 
personal property or trade fixtures are levied against Landlord or Landlord's 
property or if the assessed value of the Premises is increased by the 
inclusion therein of a value placed upon such personal property or trade 
fixtures of Tenant and if Landlord, after written notice to Tenant, pays the 
taxes based upon such increased assessment, which Landlord shall have the 
right to do regardless of the validity thereof, but only under proper protest 
if requested by Tenant, Tenant shall, upon demand, repay to Landlord the 
taxes so levied against Landlord, or the portion of such taxes resulting from 
such increase in the assessment.

    (b) If the Tenant Improvements in the Premises, whether installed, and/or 
paid for by Landlord or Tenant and whether or not affixed to the real 
property so as to become a part thereof, are assessed for real property tax 
purposes at a valuation higher than the valuation at which Tenant 
Improvements conforming to Landlord's "Building Standard" in other space in 
the Building are assessed, then the real property taxes and assessments 
levied against the Building by reason of such excess assessed valuation shall 
be deemed to be taxes levied against personal property of Tenant and shall be 
governed by the provisions of Paragraph 10(a), above. If the records of the 
county assessor are available and sufficiently detailed to serve as a basis 
for determining whether said Tenant Improvements are assess at a higher 
valuation than Landlord's Building Standard, such records shall be binding on 
both the Landlord and the Tenant. If the records of the county assessor are 
not available or sufficiently detailed to serve as a basis for making said 
determination, the actual cost of construction shall be used.

                              11. CONDITION OF PREMISES


<PAGE>
                                           
    Tenant acknowledges that neither Landlord nor any agent of Landlord has 
made any representation or warranty with respect to the Premises or the 
Building or with respect to the suitability of either for the conduct of 
Tenant's business. The taking of possession of the Premises by Tenant shall 
conclusively establish that the Premises and the Building were in 
satisfaction condition at such time.

                                   12. ALTERATIONS

    (a) Tenant shall make no alterations, additions or improvements in or to 
the Premises without Landlord's prior written consent, and then only by 
contractors or mechanics approved by Landlord. Tenant agrees that there shall 
be no construction of partitions or other obstruction which might interfere 
with Landlord's free access to mechanical installations or service facilities 
of the Building or interfere with the moving of Landlord's equipment to or 
from the enclosures containing said installations or facilities. All such 
work shall be done at such times and in such manner as Landlord may from time 
to time designate. Tenant covenants and agrees that all work done by Tenant 
shall be performed in full compliance with all laws, rules, orders, 
ordinances, regulations and requirements of all governmental, agencies, 
offices, and boards having jurisdiction, and in full compliance with the 
rules, regulations and requirements of the Insurance Service Offices formerly 
known as the Pacific Fire Rating Bureau, and of any similar body. Before 
commencing any work, Tenant shall give Landlord at least ten (10) days 
written notice of the proposed commencement of such work and shall, if 
required by Landlord, secure at Tenant's own cost and expense, a completion 
and lien indemnity bond, satisfaction to Landlord, for said work. Tenant 
further covenants and agrees that any mechanic's lien filed against the 
Premises or against the Building for work claimed to have been done for, or 
materials claimed to have been furnished to Tenant will be discharged by 
Tenant, by bond or otherwise, within ten (10) days after the filing thereof, 
at the cost and expense of Tenant. All alterations, additions or improvements 
upon the Premises made by either party, including (without limiting the 
generality of the foregoing) all wallcovering, built-in cabinet work, 
paneling and the like, shall, unless Landlord elects otherwise, become the 
property of Landlord, and shall remain upon, and be surrendered with the 
Premises, as a part thereof, at the end of the term hereof, except that 
Landlord may, by written notice to Tenant, require Tenant to remove all 
partitions, counters, railings and the like installed by Tenant, and Tenant 
shall repair all damage resulting from such removal or, at Landlord's option, 
shall pay to Landlord all costs arising from such removal.

    (b) All articles of personal property and all business and trade 
fixtures, machinery and equipment, furniture and movable partitions owned by 
Tenant or installed by Tenant at its expense in the Premises shall be and 
remain the property of Tenant and may be removed by Tenant at any time during 
the lease term when Tenant is not in default hereunder. If Tenant shall fail 
to remove all of its effects from the Premises upon termination of this Lease 
for any cause whatsoever, Landlord may, at its option, remove the same in any 
manner that Landlord shall choose, and store said  effects without liability 

<PAGE>

to Tenant for loss thereof. In such event, Tenant agrees to pay Landlord upon 
demand any and all expenses incurred in such removal, including court costs 
and attorneys' fees and storage charges at its option, without notice, sell 
said effects, or any of the same, at private sale and without legal process, 
for such price as Landlord may obtain and apply the proceeds of such sale 
upon any amounts due under this Lease from Tenant to Landlord and upon the 
expense incident to the removal and sale of said effects.

                                     13.  REPAIRS
                                           
    (a) By entry hereunder, Tenant accepts the Premises as being in good and 
sanitary order, condition and repair. Tenant shall keep, maintain and 
preserve the Premises in first class condition and repair, and shall, when 
and if needed, at Tenant's sole cost and expense, make all repairs to the 
Premises and every part thereof. Tenant shall, upon the expiration or sooner 
termination of the term hereof, surrender the Premises to Landlord in the 
same condition as when received, usual and ordinary, wear and tear excepted. 
Landlord shall have no obligation to alter, remodel, improve, repair decorate 
or paint the Premises or any part thereof, except as provided in Exhibit "B". 
  The parties hereto affirm that Landlord has made no representations to 
Tenant respecting the condition of the Premises or the Building except as 
specifically herein set forth.

    (b) Anything contained in Paragraph 13(a) above to the contrary, 
notwithstanding, Landlord shall repair and maintain the structural portions 
of the Building, including the foundation, building shell, and roof 
structure, all at Landlord's expense, unless such maintenance and repairs are 
caused in part or in whole by the act, neglect, or omission of any duty or 
Tenant, its agents, employees, or invitees, in which event Tenant shall 
reimburse Landlord, as additional rent, for the reasonable cost of such 
maintenance and repairs. Landlord shall also repair and maintain the basic 
plumbing, elevators, life safety systems and other building systems, heating 
ventilating, air conditioning and electrical systems installed or furnished 
by Landlord, the roof membrane, the parking areas, driveways, sidewalks, 
landscaping, project signs and exterior site lighting. The cost of the 
foregoing repairs and maintenance shall be billed to Tenant as operating 
costs pursuant to Paragraph 4. Landlord shall not be liable for any failure 
to make any such repairs or to perform any maintenance unless such failure 
shall persist for an unreasonable time after written notice of the need of 
such repairs or maintenance is given to Landlord by Tenant. Except as 
provided in Article 21 hereof, there shall be no abatement of rent and no 
liability of Landlord by reason of any injury to or interference with 
Tenant's business arising from the making of any repairs, alterations or 
improvements in or to any portion of the  Building or the Premises or in or 
to fixtures, appurtenances and equipment therein. Tenant waives the right to 
make repairs at Landlord's expense under any law, statute or ordinance now or 
hereafter in effect.

                                      14. LIENS

    Tenant shall not permit any mechanics, materialmen's or other liens to be 
filed against the Building nor against Tenant's leasehold interest in the 
Premises. Landlord shall 

<PAGE>


have the right at all reasonable times to post and keep posted on the 
Premises any notices which it deems necessary, for protection from such 
liens. If any such liens are filed, Landlord may, without waiving its rights 
and remedies based on such breach of Tenant and without releasing Tenant from 
any of its obligations, cause such liens to be released by any means it shall 
deem proper, including payments in satisfaction of the claim giving rise to 
such lien. Tenant shall pay to Landlord at once, upon notice by Landlord, any 
sum paid by Landlord to remove such liens, together with interest at the 
maximum rate per annum permitted by law from the date of such payment by 
Landlord.

                                15. ENTRY BY LANDLORD

    Landlord reserves and shall at any and all times have the right to enter 
the Premises to inspect the same, to supply janitor service and any service 
to be provided by Landlord to Tenant hereunder, to show the Premises to 
prospective purchasers or tenants, to post notices of nonresponsibility, to 
alter, improve or repair the Premises or any other portion of the Building, 
all without being deemed guilty of any eviction of Tenant and without 
abatement of rent. Landlord may, on order to carry, out such purposes, erect 
scaffolding and other necessary structures where reasonably required by the 
character of the work to be performed, provided that the business of Tenant 
shall be interfered with as little as is reasonably practicable. Tenant 
hereby waives any claim for damages for any injury or inconvenient to or 
interference with Tenant's business, any loss of occupancy or quite enjoyment 
of the Premises, and only other loss in, upon and about the Premises. 
Landlord shall at all times have and retain a key with which to unlock all 
doors in the Premises. any entry to the Premises obtained by Landlord by any 
of said means, or otherwise, shall not be construed or deemed to be a 
forcible or unlawful entry into the Premises, or an eviction of Tenant from 
the Premises or any portion thereof, and any damages caused on account 
thereof shall be paid by Tenant. It is understood and agreed that no 
provision of this Lease shall be construed as obligating Landlord to perform 
any repairs, alterations or decorations except as otherwise expressly agreed 
herein by Landlord.

                              16. UTILITIES AND SERVICES
                                           
    Provided that Tenant is not default under this Lease, Landlord agrees to 
furnish or cause to be furnished to the Premises the utilities and services 
described in the Standards for Utilities and Services, attached hereto as 
Exhibit C, subject to the conditions and in accordance with the standards set 
forth therein. Landlord's failure to furnish any of the foregoing items when 
such failure is caused by: (i) accident, breakage, or repairs; (ii) strikes, 
lockouts or other labor disturbance or labor dispute of any character; (iii) 
governmental regulation, moratorium or other governmental action; (iv) 
inability despite the exercise of reasonable diligence to obtain electricity, 
water or fuel; or (v) any other cause beyond Landlord's reasonable control, 
shall not result in any liability to Landlord. In addition, Tenant shall not 
be entitled to any abatement or reduction of rent by reason of such failure, 
no eviction of Tenant shall result from such failure and Tenant shall not be 
relieved from the performance of any covenant or agreement in this Lease 
because of such failure. In the event of any failure, 

<PAGE>

stoppage or interruption thereof, Landlord shall diligently attempt to resume 
service promptly.

                                    17. BANKRUPTCY
                                           
    If Tenant shall file a petition in bankruptcy under any provision of the 
Bankruptcy code as then in effect, or if Tenant shall be adjudicated a 
bankrupt in involuntary bankruptcy proceedings and such adjudication shall 
not have been vacated within thirty (30) days from the date thereof, or if a 
receiver or trustee shall be appointed of Tenant's property and the order 
appoint such receiver or trustee shall not be set aside or vacated within 
thirty (30) days after the entry, thereof, or if Tenant shall assign Tenant's 
estate or effects for the benefit of creditors, or if this Lease shall, by 
operation of law or otherwise, pass to any person or persons other than 
Tenant, then in any such event Landlord may terminate this Lease, if Landlord 
so elects, with or without notice of such election and with or without entry, 
or action by Landlord. In such case, notwithstanding any other provisions of 
this Lease, Landlord, in addition to any and all rights and remedies allowed 
by law or equity, shall, upon such termination, be entitled to possession of 
the Premises but shall surrender the Premises to Landlord. Nothing contained 
herein shall limit or prejudice the right of Landlord to recover damages by 
reason of any such termination equal to the maximum allowed by any statute or 
rule of law in effect at the time when, and governing the proceedings in 
which, such damages are to be proved; whether or not such amount is greater, 
equal to, or less than the amount of damages recoverable under the provisions 
of this Article 17.

                                 18. INDEMNIFICATION
                                           
    Tenant shall indemnify, defend and hold Landlord harmless from all claims 
arising from Tenant's use of the Premises or the conduct of its business or 
from any activity, work, or thing done, permitted or suffered by Tenant in or 
about the Premises. Tenant shall further indemnify, defend and hold Landlord 
harmless from all claims arising from any breach or default in the 
performance of any obligation to be performed by Tenant under the terms of 
this Lease, or arising from any act, neglect, fault or omission of Tenant or 
of its agents or employees, and from and against all costs, attorneys' fees, 
expenses and liabilities incurred in or about such claim or any action or 
proceeding brought thereon. In case any action or proceeding shall be brought 
against Landlord by reason of any such claim, Tenant upon notice from 
Landlord shall defend the same at Tenant's expense by counsel approved in 
writing by Landlord.

                           19. DAMAGE TO TENANT'S PROPERTY.
                                           
    Notwithstanding the provisions of Article 18 to the contrary, Landlord or 
its agents shall not be liable for (i) any damage to any property entrusted 
to employees of the Building, (ii) loss or damage to any property by theft or 
otherwise, (iii) any injury, or damage to persons or property resulting from 
fire, explosion, falling plaster, steam gas, electricity, water or rain which 
may leak from any part of the Building or from the pipes, 

<PAGE>

appliances or plumbing work therein or from the roof, street or subsurface or 
from any other place or resulting from dampness or (iv) any other cause 
whatsoever. Landlord or its agents shall not be liable for interference with 
light or other incorporeal hereditaments nor shall Landlord be liable for any 
latent defect in the Premises or Building. Tenant shall give prompt notice to 
Landlord in case of fire or accidents in the Premises or in the Building or 
of defects therein or in the fixtures or equipment.

                                20. TENANT'S INSURANCE
                                           
    (a) Tenant shall, during the term hereof and any other period of 
occupancy, at it s sole costs and expense, keep in full force and effect the 
following insurance:

         (i) Standard form property insurance insuring against the perils of 
fire, extended coverage, vandalism, malicious mischief, special extended 
coverage ("All Risk") and sprinkler leakage. This insurance policy shall be 
upon all property owned by Tenant, for which Tenant is legally liable or that 
was installed at Tenant's expense, and which is located in the Building 
including, without limitation, furniture, fittings, installations, fixtures 
(other than Tenant Improvements installed by Landlord), and any other 
personal property, in an amount not less than the full replacement cost 
thereof. In the event that there shall be a  dispute as to the amount which 
comprises full replacement cost, the decision of Landlord or any mortgagees 
of Landlord shall be conclusive. This insurance policy shall also be upon 
direct or indirect loss of Tenant's earnings attributable to Tenant's 
inability to use fully or obtain access to the Premises or Building in an 
amount as will property reimburse Tenant. Such policy shall name Landlord and 
any mortgagees of Landlord as insured parties, as their respective interests 
may appear.

         (ii) Comprehensive General Liability insurance insuring Tenant 
against any liability arising out of the lease, use, occupancy or maintenance 
of the Premises and all areas appurtenant thereto. Such insurance shall be in 
the amount of $1,000,000.00 combined single limit for injury to, or death of 
one or more persons in an occurrence, and for damage to tangible property 
(including loss of use) in an occurrence, with such liability amount to be 
adjusted from year to year to reflect increases in the Consumer Price Index. 
The policy shall insure the hazards of premises and operations, independent 
contractors, contractual liability (covering the indemnity contained in 
Paragraph 18 hereof) and shall (1) name Landlord as an additional', insured, 
and (2) contain a provision that "the insurance provided the Landlord 
hereunder shall be primary, and noncontributing with any other insurance 
available to the Landlord."

         (iii) Workers' compensation and employer's liability insurance (as 
required by state law).

         (iv) Any other form or forms of insurance as Tenant or Landlord or 
any mortgagees of Landlord may reasonably require from time to time in form, 
in amounts and for insurance risks against which a prudent tenant would 
protect itself.

<PAGE>

    (b) All policies shall be written in a form satisfaction, to Landlord and 
shall be taken out with insurance companies holding a General Policyholders 
Rating of "A" and a Financial Rating of "X" or better, as set forth in the 
most current issue of Bests Insurance Guide. Within ten (10) days after the 
execution of this Lease, Tenant shall deliver to Landlord copies of policies 
or certificates evidencing the existence of the amounts and forms of coverage 
satisfactory to Landlord. No such policy shall be cancelable or reducible in 
coverage except after thirty (30) days prior written notice to Landlord. 
Tenant shall, within ten (10) days prior to the expiration of such policies, 
furnish Landlord with renewals or "binders" thereof, or Landlord may order 
such insurance and charge the cost thereof to Tenant as additional rent. If 
Landlord obtains any insurance that is the responsibility of Tenant under 
this section, Landlord shall deliver to Tenant a written statement setting 
forth the cost of any such insurance and showing in reasonable detail the 
manner in which it has been  computed.

                              21. DAMAGE OR DESTRUCTION
                                           
    (a) If the Building and/or the Premises is damaged by fire or other 
perils covered by Landlord's insurance, Landlord shall have the following 
rights and obligations:

         (i) In the event of total destruction, Landlord shall, as Landlord's 
option, commence repair, reconstruction and restoration of the Building 
and/or the Premises as soon as reasonably possible, and diligently prosecute 
the same to completion, in which event this Lease shall remain in full force 
and effect. If Landlord elects not to so repair, reconstruct or restore the 
Building and/or the Premises, this Lease shall terminate as of the date of 
such total destruction. In either event, Landlord shall give Tenant written 
notice of its intention within sixty (60) days after the date of damage or 
destruction.

         (ii) In the event of a partial destruction of the Building and/ or 
the Premises, Landlord shall promptly restore the Building and/or the 
Premises unless Landlord elects to terminate this Lease as permitted herein. 
Landlord shall have the right to terminate this Landlord if (1) the damage to 
the Building and/or the Premises exceeds twenty-five percent (25%) of the 
full insurable value thereof, (2) the damage to the Building and/or the 
Premises is such that the Building and/or the Premises cannot be repaired, 
reconstructed or restored within one hundred eighty (180) days from the date 
of damage or destruction, or (3) insurance proceeds received by Landlord will 
not be sufficient to cover the cost of such repairs, reconstruction and 
restoration. Landlord shall give written notice to Tenant of its intention 
within sixty (60) days after the date of damage or destruction. If Landlord 
elects not to restore the Building and/or the Premises, this Lease shall be 
deemed to have terminated as of the date of such partial destruction.

    (b) Upon any termination of this Lease, Landlord under any of the 
provisions of this Article 21, the parties shall be released without further 
obligation to the other from the date possession of the Premises is 
surrendered to Landlord except for items which have therefore accrued and are 
then unpaid.

<PAGE>

    (c) In the event of repair, reconstruction and restoration by Landlord as 
herein provided, the rental payable under this Lease shall be abated 
proportionately with the degree to which Tenant's use of the Premises is 
impaired during the period of such repair, reconstruction or restoration. 
Tenant shall not be entitled to any compensation or damages for loss in the 
use of the whole or any part of the Premises and/or any inconvenience or  
annoyance occasioned by such damage, repair, reconstruction or restoration.

    (d) Tenant shall not be released from any of its obligations under this 
Lease except to the extent and upon the conditions expressly stated in this 
Article 21. Notwithstanding anything to the contrary contained in this 
Article 21, if Landlord is delayed or prevented from repairing or restoring 
the damaged Premises within one year after the occurrence of such damage or 
destruction by reason of acts of God, war, governmental restrictions, 
inability to obtain the necessary labor or materials, or other cause beyond 
the control of Landlord, Landlord shall be relieved of its obligation to make 
such repairs of restoration and Tenant shall be released from its obligations 
under this Lease as of the end of said one year period.

    (e) If damage is due to any cause other than fire or other peril covered 
by All-Risk insurance, Landlord may elect to terminate this Lease.

    (f) If Landlord is obligated to or elects to repair or restore as herein 
provided, Landlord shall be obligated to make repair or restoration only of 
those portions of the Building and the Premises which were originally 
provided at Landlord's expense, and the repair and restoration of items not 
provided at Landlord's expense shall be the obligation of Tenant.

    (g) Notwithstanding anything to the contrary contained in this Article 
21, Landlord shall not have any obligation whatsoever to repair, reconstruct 
or restore the Premises when the damage resulting from any casualty covered 
under this Article 21, occurs during the last twelve (12) months of the term 
of this Lease or any extension hereof.

    (h) The provisions of California Civil Code Section 1932, Subsection 2, 
and Section 1933, Subsection 4, which permit termination of a lease upon 
destruction of the leased premises, are hereby waived by Tenant; and the 
provisions of this article shall govern in case of such destruction.

                             22. EMINENT DOMAIN
                                           
    If all of the Premises, or such part thereof as shall substantially 
interfere with Tenant's use and occupancy of the Premises, shall be taken for 
any public or quasi-public purpose by any lawful power or authority by 
exercise of the right of appropriation, condemnation or eminent domain, or 
sold to prevent such taking, either party may terminate this Lease effective 
as of the date possession is required to be surrendered to said authority. 
Tenant shall not assert any claim against Landlord or the taking authority 
for any compensation because of such taking, and Landlord shall be entitled 
to receive the 

<PAGE>

entire amount of any award without  deduction for any estate or interest of 
Tenant. If neither party terminates this Lease as permitted herein, Landlord 
shall be entitled to the entire amount of the award without deduction for any 
estate or interest of Tenant, Landlord shall restore the Premises to 
substantially their same condition prior to such partial taking, and rent 
shall be abated for the time and to the extent Tenant is prevented from using 
the Premises on account of such taking and restoration. Nothing contained in 
this paragraph shall be deemed to give Landlord any interest in any award 
made to Tenant for the taking of personal property and fixtures belonging to 
Tenant or for Tenant's moving or relocation expenses.

                          23. DEFAULTS AND REMEDIES
                                           
    (a) The occurrence of any one or more of the following events shall 
constitute a default hereunder by Tenant:

         (i) The vacation or abandonment of the Premises by Tenant. 
Abandonment is herein defined to include, but is not limited to, any absence 
by Tenant from the Premises for five (5) business days or longer while in 
default of any provision of this Lease.

         (ii) The failure by Tenant to make any payment of rent where such 
failure shall continue for a period of three (3) days after written notice 
thereof from Landlord to Tenant; provided however, that any such notice shall 
be in lieu of, and not in addition to, any notice required under California 
Code of Civil Procedure Section II6I regarding unlawful detainer actions.

         (iii) The failure by Tenant to observe or perform any of the express 
or implied covenants or provisions of this Lease to be observed or performed 
by Tenant, other than as specified in Subparagraph 23(a)(i) or (ii) above, 
where such failure shall continue for a period of ten (10) days after written 
notice thereof from Landlord to Tenant. Any such notice shall be in lieu of, 
and not in addition to, any notice required under California Code of Civil 
Procedure Section II6I regarding unlawful detainer actions. If the nature of 
Tenant's default is such that more than ten (10) days are reasonably required 
for its cure, then Tenant shall not be deemed to be in default if Tenant 
shall commence such cure within said ten-day period and thereafter diligently 
prosecute such cure to completion, which completion shall occur not later 
than sixty (60) days from the date of such notice from Landlord.

         (iv) (1) The making by Tenant of any general assignment for the 
benefit of creditors' (2) the filing by or against Tenant of a petition to 
have Tenant adjudged a bankrupt or a petition for reorganization or 
arrangement under any law relating to bankruptcy (unless, in the case of  a 
petition filed against Tenant, the same is dismissed within thirty (30) 
days); (3) the appointment of a trustee or receiver to take possession of 
substantially all of Tenant's assets located at the Premises or of Tenant's 
interest in this Lease, where possession is not restored to Tenant within 
thirty (30) days; or (4) the attachment, execution or other judicial seizure 
of substantially all of Tenant's assets

<PAGE>

located at the Premises or of Tenant's interest in this Lease where such 
seizure is not discharged within thirty (30) days.

    (b) In the event of any such default by Tenant, in addition to any other 
remedies available to Landlord at law or in equity, Landlord shall have the 
immediate option to terminate this Lease and all rights of Tenant hereunder. 
In the event that Landlord shall elect to so terminate this Lease then 
Landlord may recover from Tenant:

          (i) the worth at the time of award of any unpaid rent which had 
been earned at the time of such termination; plus

         (ii) the worth at the time of award of the amount by which the 
unpaid rent which would have been earned after termination until the time of 
award exceeds the amount of such rental loss that Tenant proves could have 
been reasonably avoided; plus

         (iii) the worth at the time of award of the amount by which the 
unpaid rent for the balance of the term after the time of award exceeds the 
amount of such rental loss that Tenant proves could be reasonably avoided; 
plus

         (iv) any other amount necessary to compensate Landlord for all 
detriment approximately caused by Tenant's failure to perform Tenant's 
obligations under this Lease or which in the ordinary course of things would 
be likely to result therefrom.

As used in Subparagraphs 23(b)(i) and (ii) above, the "worth at the time of 
award" is computed by allowing interest at the maximum rate permitted by law. 
As used in Subparagraph 23(b)(iii) above, the "worth at the time of award" is 
computed by discounting such amount at the discount rate of the Federal 
Reserve Bank of San Francisco at the time of award plus one percent (1%).

    (c)  In the event of any such default Landlord shall also have the right 
to continue this Lease in full force and effect, and this Lease shall 
continue in full force and effect as long as Landlord does not terminate this 
Lease, and Landlord shall have the right to collect rent as it becomes due.

    (d)  Landlord shall also have the right, with or  without terminating 
this Lease, to reenter the Premises and remove all persons and property from 
the Premises; such property may be removed and stored in a public warehouse 
or elsewhere at the cost of and for the account of Tenant.  No reentry or 
taking possession of the Premises by Landlord pursuant to the Paragraph 23(c) 
shall be construed as an election to terminate this Lease unless a written 
notice of such intention is given to Tenant or unless the termination thereof 
is decreed by a court of competent jurisdiction.

    (e)  All rights, options and remedies of Landlord contained in this Lease 
shall be constructed and held to be cumulative, and no one of them shall be 
exclusive of the other.  Landlord shall have the right to pursue any one or 
all of such remedies or any other 

<PAGE>

remedy or relief which may be provided by law, whether or not stated in the 
Lease.  No waiver or any default of Tenant hereunder shall be implied from 
any acceptance by Landlord or any rent or other payments due hereunder or any 
omission by Landlord to take any action on account of such default if such 
default persists or is repeated, and no express waiver shall affect defaults 
other than as specified in said waiver.  The consent or approval of Landlord 
to or of any act by Tenant requiring Landlord's consent or approval shall not 
be deemed to waive or render unnecessary Landlord's consent or approval to or 
of any subsequent similar acts by Tenant.

                            24.  ASSIGNMENT AND SUBLETTING
                                           
    (a)  Tenant shall not voluntarily assign or encumber its interest in this 
Lease or in the Premises, or sublease all or any part of the Premises, or 
allow any other person or entity to occupy or use all or any part of the 
Premises, without first obtaining Landlord's prior written consent.  Any 
assignment, encumbrance or sublease without Landlord's prior written consent 
shall be voidable, at Landlord's election, and shall constitute a default and 
at the option of the Landlord shall result in a termination of this Lease.  
No consent to assignment, encumbrance, or sublease shall constitute a further 
waiver of the provisions of this paragraph.  Tenant shall notify Landlord in 
writing of Tenant's intent to sublease, encumber or assign this Lease and 
Landlord shall, within fifteen (15) days of receipt of such written notice, 
elect one of the following:  (i) consent to such proposed assignment or 
sublease;  (ii) refuse such consent, which refusal shall be on reasonable 
grounds, or (iii) elect to terminate this Lease.

    (b)  As a condition for granting its consent to any assignment, 
encumbrance or sublease, fifteen (15) days prior to any anticipated 
assignment or sublease Tenant shall give Landlord written notice (the 
"Assignment Notice"), which shall set forth the name, address and business of 
the proposed assignee or sublessee, information (including references) 
concerning the character, ownership and financial condition of the proposed 
assignee or sublessee, the Assignment Date, any ownership or commercial 
relationship between Tenant and the proposed assignee or sublessee, all in 
such detail as Landlord shall reasonably require. If Landlord requests 
additional detail, the Assignment Notice shall not be deemed to have been 
received until Landlord received such additional detail, and Landlord may 
withhold consent to any assignment or sublease until such additional detail 
is provided to it.  Further, Landlord may require that the sublessee or 
assignee remit directly to Landlord on a monthly basis, all monies due to 
Tenant by said assignee or sublessee.

    (c)  The consent by Landlord to any assignee of this Lease or sublessee 
of the Premises from obtaining the express written consent of Landlord to any 
further assignment or subletting or as releasing Tenant or any assignee or 
sublessee of Tenant from any liability or obligation hereunder whether or not 
then accrued.  In the event Landlord shall consent to an assignment or 
sublease, Tenant shall pay Landlord as additional rent a reasonable 
attorneys' and administration fee not to exceed $500 for costs incurred in 
connection with evaluating the Assignment Notice.  This section shall be 
fully applicable 

<PAGE>

to all further sales, hypothecation, transfers, assignments and subleases of 
any portion of the by any successor assignee of Tenant, or any sublessee of 
the Premises.

    (d)  As used in this section, the subletting of substantially all of the 
Premises for substantially all of the remaining term of this Lease shall be 
deemed an assignment rather than a sublease.  Notwithstanding the foregoing, 
Landlord shall consent to the assignment, sale or transfer if the Assignment 
Notice states that Tenant desires to assign the Lease to any entity into 
which Tenant is merged, with which Tenant is consolidated or which acquires 
all or substantially all of the assets of Tenant, provided that the assignee 
first executes, acknowledges and delivers to Landlord an agreement whereby 
the assignee agrees to be bound by all of the covenants and agreements in 
this Lease which Tenant has agreed to keep, observe or perform, that the 
assignee agrees that the provisions of this section shall be binding upon it 
as if it were the original Tenant hereunder and that the assignee shall have 
a net worth (determined in accordance with generally accepted accounting 
principles consistently applied) immediately after such assignment which is 
at least equal to the net worth (as so determined) of Tenant at the 
commencement of this Lease.

    (e) Except as provided above, Landlord's consent to any sublease shall 
not be unreasonably withheld. A condition to such consent shall be delivery 
by Tenant to Landlord of a true copy of any such sublease. If for any 
proposed assignment or sublease Tenant receives rent or other consideration, 
either initially or over the term of the  assignment or sublease, in excess 
of the rent called for hereunder, or, in case of the sublease of a portion of 
the Premises, in excess of such rent fairly allocable to such portion, after 
appropriate adjustments to assure that all other payments called for 
hereunder are taken into account, Tenant shall pay to Landlord as additional 
rent hereunder fifty percent (50%) of the excess of each such payment or 
rent, less any documented expenses incurred by Tenant in direct relation to 
the assignment or sublease, or other consideration received by Tenant 
promptly after its receipt. Landlord's waiver or consent to any assignment or 
subletting shall not relieve Tenant from any obligation under this lease. The 
parties intend that the preceding sentence shall not apply to any sublease 
rentals respecting a portion of the Premises that during the entire term of 
this Lease was not occupied by Tenant for its own use, but was always 
subleased by Tenant and/or kept vacant. For the purposes of this section, the 
rent for each square foot of floor space in the Premises shall be deemed 
equal.

    (f)  Tenant may assign the Lease or may sublet the Premises or any part 
thereof without Landlord's prior consent, to any subsidiary, affiliate or 
controlled corporation, or to any corporation into which Tenant may be 
converted or with which it may merge, provided said entity has comparable 
financial strength and agrees to accept the Lease Agreement in it's then 
current condition, and provided that the assignee or sublessee's use is 
compatible with the building.

                                  25. SUBORDINATION


<PAGE>
                                           
    Without the necessity of any additional document being executed by Tenant 
for the purpose of effecting a subordination, and at the election of Landlord 
or any mortgagee with a lien on the building or any ground lessor with 
respect to the building, this Lease shall be subject and subordinate at all 
times to:

    (i) All ground leases or underlying leases which may now exist or 
hereafter be executed affecting the building or the land upon which the 
building is situated or both;

    (ii) The lien of any mortgage or deed of trust which may now exist or 
hereafter be executed in any amount for which the building, land, ground 
leases, or underlying leases, or Landlord's interest or estate in any of said 
items is specified as security. Notwithstanding the foregoing, Landlord shall 
have the right to subordinate or cause to be subordinated any such leases or 
underlying leases or any such liens to this Lease. In the event that any 
ground lease or underlying lease terminates for any reason or any mortgage or 
deed of trust is foreclosed or a conveyance in lieu of foreclosure is made 
for any reason, Tenant shall, notwithstanding any subordination, attorn to  
and become the Tenant of the successor in interest to Landlord, at the option 
of such successor in interest. Tenant covenants and agrees to execute and 
deliver, upon demand by Landlord and in the form requested by Landlord, any 
additional documents evidencing the priority or subordination of this Lease 
with respect to any such ground leases or underlying leases or in the lien of 
any such mortgage or deed of trust.

                               26. ESTOPPEL CERTIFICATE
                                           
    (a) Within ten (10) days following any written request which Landlord may 
make from time to time, Tenant shall execute and deliver to Landlord a 
statement certifying: (i) the date of commencement of this Lease; (ii) the 
fact that this Lease is unmodified and in full force and effect (or, if there 
have been modifications); (iii) the date to which the rental and other sums 
payable under this Lease have been paid; (iv) that there are no current 
defaults under this Lease by either Landlord or Tenant except as specified in 
Tenant's statement; and (v) such other matters requested by Landlord. 
Landlord and Tenant intend that any statement delivered pursuant to this 
Article 26 may be relied upon by any mortgage, beneficiary, purchaser, or 
prospective purchaser of the building or any interest therein.

    (b) Tenant's failure to deliver such statement within such time shall be 
conclusive upon Tenant: (i) that this Lease is in full force and effect, 
without modification except as may be represented by Landlord, (ii) that 
there are no uncured defaults in Landlord's performance, and (iii) that not 
more than one month's rental has been paid in advance.

                                27. BUILDING PLANNING
                                           
    In the event Landlord requires the Premises for use in conjunction with 
another suite or for other reasons connected with the Building planning 
program, upon notifying Tenant in writing, Landlord shall have the right to 
move to other space in the Building of 

<PAGE>

which the Premises forms a part, at Landlord's sole costs and expense, and 
the terms and conditions of the original Lease shall remain in full force and 
effect, save and expecting that a revised Exhibit "A" shall become part of 
this Lease and shall reflect the location of the new space. However, if the 
new space does not meet with Tenant's approval, Tenant shall have the right 
to cancel this Lease upon giving Landlord thirty (30) days notice within ten 
(10) days of receipt of Landlord's notification.

                              28. RULES AND REGULATIONS
                                           
    Tenant shall faithfully observe and comply with the "Rules and 
Regulations," a copy of which is attached hereto  and marked Exhibit D and 
all reasonable and nondiscriminatory modifications thereof and additions 
thereto from time to time put into effect by Landlord. Landlord shall not be 
responsible to Tenant for the violation or nonperformance by any other tenant 
or occupant of the building of any of said Rules and Regulations.

                                 29. CONFLICT OF LAW
                                           
This Lease shall be governed by and construed pursuant to the laws of the 
State of California.

                              30. SUCCESSORS AND ASSIGNS
                                           
    Except as otherwise provided in this Lease, all of the covenants, 
conditions, and provisions of this Lease shall be binding upon and shall 
inure to the benefit of the parties hereto and their respective heirs, 
personal representatives, successors, and assigns.

                              31. SURRENDER OF PREMISES
                                           
    The voluntary or other surrender of this Lease by Tenant, or a mutual 
cancellation thereof, shall not work a merger, and shall, at the option of 
Landlord, operate as an assignment to it of any or all subleases or 
subtenancies.

                                 32. ATTORNEY'S FEES
                                           
    (a) If Landlord should bring suit for possession of the Premises, for the 
recovery of any sum due under this Lease, or because of the breach of any 
provisions of this Lease, or for any other relief against Tenant hereunder, 
or in the event of any other litigation between the parties with respect to 
this Lease, then all costs and expenses, including reasonable attorney's 
fees, incurred by the prevailing party therein shall be paid by the other 
party, which obligation on the part of the other party shall be deemed to 
have accrued on the date of the commencement of such action and shall be 
enforceable whether or not the action is prosecuted to judgment.

                              33. PERFORMANCE BY TENANT
                                           
<PAGE>


    All covenants and agreements to be performed by Tenant under any of the 
terms of this Lease shall be performed by Tenant at Tenant's sole cost and 
expense and without any abatement of rent. If Tenant shall fail to pay any 
sum of money owed to any party other than Landlord, for which it is liable 
hereunder, or if Tenant shall fail to perform any other act on its part to be 
performed hereunder and such failure shall continue for ten (l0) days after 
notice thereof by Landlord, Landlord may, without waiving or releasing Tenant 
from obligations of Tenant, but shall not be obligated to, make any such 
payment or perform any such  other act to be made or performed by Tenant. All 
sums so paid by Landlord and all necessary incidental costs together with 
interest thereon at the maximum rate permissible by law, from the date of 
such payment by Landlord, shall be payable to Landlord on demand. Tenant 
covenants to pay any such sums and Landlord shall have (in addition to any 
other right or remedy of Landlord) all rights and remedies in the event of 
the nonpayment thereof by Tenant as are set forth in Article 23 hereof.

                               34. MORTGAGEE PROTECTION
                                           
    In the event of any default on the part of Landlord, Tenant will give 
notice by registered or certified mail to any beneficiary of a deed of trust 
or mortgage covering the Premises whose address shall have been furnished to 
Tenant, and shall offer such beneficiary or mortgagee a reasonable 
opportunity to cure the default, including time to obtain possession of the 
Premises by power of sale or a judicial foreclosure, if such should prove 
necessary to effect a cure.

                              35. DEFINITION OF LANDLORD
                                           
    The term "Landlord", as used in this Lease, so far as covenants or 
obligations on the part of the Landlord are concerned, shall be limited to 
mean and include only the owners, at the time in question, of the fee title 
of the Premises or the lessees under any ground lease, if any. In the event 
of any transfer, assignment, or other conveyances, the then grantor shall be 
automatically freed and relieved from and after the date of such transfer, 
assignment, or conveyance of all liability as respects the performance of any 
covenants or obligations on the part of Landlord contained in this Lease 
thereafter to be performed. Without further agreement, the transferee of such 
title shall be deemed to have assumed and agreed to observe and perform any 
and all obligations of Landlord hereunder, during its ownership of the 
Premises. Landlord may transfer its interest in the Premises without the 
consent of Tenant and such transfer or subsequent transfer shall not be 
deemed a violation on Landlord's part of any of the terms and conditions of 
this Lease.

                                      36. WAIVER
                                           
    The waiver by Landlord of any breach of any term, covenant, or condition 
herein contained shall not be deemed to be a waiver of any subsequent breach 
of the same or any other term, covenant, or condition herein contained, nor 
shall any custom or practice which may grow up between the parties in the 
administration of the terms hereof be 

<PAGE>

deemed a waiver of or in any way affect the right of Landlord to insist upon 
the performance by Tenant in strict accordance with said terms. The 
subsequent acceptance of rent hereunder  by Landlord shall not be deemed to 
be a waiver of any preceding breach by Tenant of any term, covenant, or 
condition of this Lease, other than the failure of Tenant to pay the 
particular rent so accepted, regardless of Landlord's knowledge of such 
preceding breach at the time of acceptance of such rent.

                             37. IDENTIFICATION OF TENANT
                                           
    If more than one person executes this Lease as Tenant:

observing and performing of all of the terms, covenants, conditions, 
provisions, and agreements of this Lease to be kept, observed and performed 
by Tenant, and

    (ii) The term "Tenant" as used in this Lease shall mean and include each 
of them jointly and severally. The act of or notice from, or notice or refund 
to, or the signature of any one or more of them, with respect to the tenancy 
of the Lease, including, but not limited to any renewal, extension, 
expiration, termination, or modification of this Lease, shall be binding upon 
each and all of the persons executing this Lease as Tenant with the same 
force and effect as if each and all of them had so acted or so given or 
received such notice or refund or so signed.

                                     38. PARKING
                                           
    The use by Tenant, its employees and invitees, of the parking facilities 
of the building shall be on the terms and conditions set forth in Exhibit E 
attached hereto and by this reference incorporated herein and shall be 
subject to such other agreement between Landlord and Tenant as may 
hereinafter be established.

                                39. TERMS AND HEADINGS
                                           
    The words "Landlord" and "Tenant" as used herein shall include the plural 
as well as the singular. Words used in any gender include other genders. The 
paragraph headings of this Lease are not a part of this Lease and shall have 
no effect upon the construction or interpretation of any part hereof.

                               40. EXAMINATION OF LEASE
                                           
    Submission of this instrument for examination or signature by Tenant does 
not constitute a reservation of or option for lease, and it is not effective 
as a lease or otherwise until execution by and delivery to both Landlord and 
Tenant.

                                       41. TIME


<PAGE>
                                           
    Time is of the essence with respect to the performance of every provision 
of this Lease in which time or performance is a factor.

                           42. PRIOR AGREEMENT; AMENDMENTS
                                           
    This Lease contains all of the agreements of the parties hereto with 
respect to any matter covered or mentioned in this Lease, and no prior 
agreement or understanding pertaining to any such matter shall be effective 
for any purpose. No provisions of this Lease may be amended or added to 
except by an agreement in writing signed by the parties hereto or their 
respective successors in interest.

                                   43. SEPARABILITY
                                           
    Any provision of this Lease which shall prove to be invalid, void, or 
illegal in no way affects, impairs, or invalidates any other provision 
hereof, and any such other provisions shall remain in full force and effect.

                                    44. RECORDING
                                           
    Neither Landlord nor Tenant shall record this Lease nor a short form 
memorandum thereof without the consent of the other.

                                     45. CONSENTS
                                           
Whenever the consent of either party is required hereunder such consent shall 
not be unreasonably withheld.

                             46. LIMITATION OF LIABILITY
                                           
    In consideration of the benefits accruing hereunder, Tenant and all 
successors and assigns covenant and agree that, in the event of any actual or 
alleged failure, breach, or default hereunder by Landlord:

    (a)  The sole exclusive remedy shall be against the Landlord's interest 
in the building;

    (b)  No partner of Landlord shall be sued or named as a party in any suit

partnership);

    (c)  No service of process shall be made against any partner of Landlord 
(except as may be necessary to secure jurisdiction of the partnership);

plead to any service of process;

<PAGE>

    (g)  No writ of execution will ever be levied against the assets of any 
partner of Landlord;

    (h)  These covenants and agreements are enforceable both by Landlord and

                                      47. RIDERS
                                           
    Clauses, plats and riders, if any, signed by Landlord and Tenant and 
affixed to this Lease are a part hereof.

                                  48. FORCE MAJEURE
                                           
    Unless otherwise specifically provided herein if Landlord shall be 
delayed or hindered in or prevented from the performance of any act required 
of Landlord hereunder by reason of strikes, lockouts, labor disputes or 
disturbances inability to procure materials failure of power restrictive 
governmental laws or regulations riots insurrection ware or any other reason 
of a like nature beyond Landlord's reasonable control then performance of 
such act shall be excused for the period of the delay and the period for the 
performance of such act shall be extended for a period equivalent to the 
period of such delay.

                             49. MODIFICATION FOR LENDER
                                           
    If in connection with obtaining construction interim or permanent 
financing for the Building the lender shall request reasonable modifications 
in this Lease as a condition to such financing Tenant will not unreasonably 
withhold delay or defer its consent thereto provided that such modifications 
do not increase the obligations of Tenant hereunder or materially adversely 
affect the leasehold interest hereby created or Tenant's rights hereunder.

                                 50. OPTION TO EXTEND
                                           
    (a)  Provided that Tenant is not in default hereunder either at the time 
of exercise or at the time the extended term commences Tenant shall have the 
option to extend the initial term of this Lease for one (1) additional period 
of three (3) years ("Option Period") on the same terms covenants and 
conditions provided herein except that upon such renewal the monthly 
installments of Annual Basic Rent due hereunder shall be determined at the 
time notice to extend is given. Tenant shall exercise its option by giving 
Landlord written notice ("Option Notice") no later than ninety (90) days 
prior to the expiration of the initial term.

<PAGE>

    (b)  The monthly installments of Annual Basic Rent for the Option Period 
shall be determined as follows:

         (i) Within fifteen (15) business days after Landlord's receipt of 
the Option Notice the parties shall attempt to agree on the monthly rent for 
the Option Period in question based upon ninety-five percent (95%) of the 
then fair market rental value of the Premises. If the parties agree on the 
monthly rent for the Option Period within such fifteen (15) day period they 
shall immediately execute an amendment to this Lease stating the monthly rent 
for the Option Period. In no event shall ninety-five percent (95%) of the 
then fair market monthly rental value of the Premises for the Option Period 
be less than the monthly installments of Annual Basic Rent last payable under 
the Lease.

         (ii) The "then fair market rental value of the Premises" shall mean 
the fair market monthly rental value of the premises as of the commencement 
of the Option Period taking into consideration the uses permitted under this 
Lease the quality size design and location of the Premises and comparable 
buildings located within a one (1) mile radius of the Premises. In no event 
shall ninety-five percent (95%) of the then fair market monthly rental value 
of the Premises for the Option Period be less than the monthly installments 
of Annual Basic Rent last payable under the Lease.

         (iii) Within seven (7) days after the expiration of the fifteen (15) 
day period each party at its cost and by giving notice to the other party 
shall appoint a real estate appraiser or commercial leasing salesperson 
("Appraiser") with at least five (5) years' full-time commercial appraisal or 
leasing experience in the area in which the Premises are located to appraise 
and set the then fair market monthly rent for the Premises for the Option 
Period.

    (c) If Tenant objects to the monthly rent that has been determined Tenant 
shall have the right to rescind its exercise of the option to extend and have 
this Lease expire at the end of the initial term provided that Tenant pays 
for all reasonable costs incurred by Landlord in connection with the 
appraisal procedure. Tenant's election to allow this Lease to expire at the 
end of the initial term must be exercised by delivering written notice of 
exercise to Landlord within ten (10) days after the rent determination 
procedure has been completed and Tenant has received notice of the monthly 
rent as determined by appraisal. If Tenant does not so exercise its election 
to terminate this Lease within the ten (10) day period the initial term of 
this Lease shall be extended as provided in this paragraph. Notwithstanding 
the foregoing if Tenant elects to so rescind exercise of its option to extend 
and at the time of such  election there are less than ninety (90) days 
remaining on the initial term of the Lease then the termination of this Lease 
shall not be effective until ninety (90) days after Landlord's receipt of 
Tenant's notice of rescission. During any period that the term of this Lease 
is so extended beyond the original termination date Tenant shall be required 
to pay the amount of monthly rent determined pursuant to the appraisal 
procedure.

    (d) This option to extend and any rights granted to Tenant hereunder 
shall be 

<PAGE>


personal to Tenant and any of its affiliates and subsidiaries. No rights 
granted to Tenant pursuant to this paragraph shall be in any way applicable

                                      EXHIBIT C
                         STANDARDS FOR UTILITIES AND SERVICES

    The following Standards for Utilities and Services are in effect. Landlord
reserves the right to adopt nondiscriminatory modifications and additions
hereto.

    As long as Tenant is not in default under any of the terms, covenants,
conditions, provisions, or agreements of this Lease, Landlord shall:

    (a) Provide non-attended automatic elevator facilities Monday through
Friday, except holidays, from 8:00 a.m. to 6:00 p.m., and have one elevator
available at all other times.

    (b) On Monday through Friday, except holidays, from 8:00 a.m. - 6:00 p.m. 
(and other times for a reasonable additional charge to be fixed by Landlord), 
ventilate the Premises and furnish air conditioning or heating on such days 
and hours, when in the judgement of Landlord it may be required for the 
comfortable occupancy of the Premises. The air conditioning system achieves 
maximum cooling when the window coverings are closed. Landlord shall not be 
responsible for room temperatures if Tenant does not keep all window 
coverings in the Premises closed whenever the system is in operation. Tenant 
agrees to cooperate fully at all times with Landlord, and to abide by all 
regulations and requirements which Landlord may prescribe for the proper 
function and protection of the air conditioning system. Tenant agrees not to 
connect any apparatus, device, conduit, or pipe to the building chilled and 
hot water air conditioning supply lines. Tenant further agrees that neither 
Tenant nor its servants, employees, agents, visitors, licensees, or 
contractors shall at any time enter mechanical installations or facilities of 
the building or adjust, tamper with, touch or otherwise in any manner affect 
said installations or facilities. The cost of maintenance and service calls 
to adjust and regulate the air conditioning system shall be charged to Tenant 
if the need for maintenance work results from either Tenant's adjustment of 
room thermostats or Tenant's failure to comply with its results from either 
Tenant's adjustment of room thermostats or Tenant's failure to comply with 
its obligations under this section, including keeping window coverings closed 
as needed. Such work shall be charged at hourly rates equal to then current 
journeymen's wages for air conditioning mechanics.

    (c) Landlord shall furnish to the Premises, during the usual business hours
on business days, electric current sufficient for normal office use. Tenant
agrees, should its electrical installation or electrical consumption be in
excess of the aforesaid quantity or extend beyond normal  business hours, to
reimburse Landlord monthly for the measured consumption at the average cost per
kilowatt hour charged to the building during the period. If a separate meter is
not installed at Tenant's cost, such excess costs will be established by an
estimate agreed upon by Landlord and Tenant, and if the parties fail to agree,
as established by an independent licensed engineer. Said estimates to be
reviewed and adjusted quarterly. Tenant agrees not to use any apparatus or
device in, or upon, or 

<PAGE>

about the Premises which may in any way increase the amount of such 
services usually furnished or supplied to said Premises, and Tenant further 
agrees not to connect any apparatus or device with wire, conduits, pipes, or 
other means by which such services are supplied, for the purpose of using 
additional or unusual amounts of such services without written consent of 
Landlord. Should Tenant use the same to excess, the refusal on the part of 
Tenant to pay upon demand of Landlord the amount established by Landlord for 
such excess charge shall constitute a breach of the obligation to pay rent 
under this Lease and shall entitle Landlord to the rights therein granted for 
such breach. At all times Tenant's use of electric current shall never exceed 
the capacity of the feeders to the building or the risers or wiring 
installation and Tenant shall not install or use or permit the installation 
or use of any computer or electronic data processing equipment in the 
premises, without the prior written consent of Landlord.

    (d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses, or consumes water for any purposes
in addition to ordinary drinking and lavatory purposes of which fact Tenant
constitutes Landlord to be the sole judge, Landlord may install a water meter
and thereby measure Tenant's water consumption for all purposes. Tenant shall
pay Landlord for the cost of the meter and the cost of the installation thereof
and throughout the duration of Tenant's occupancy, Tenant shall keep said meter
and installation equipment in good working order and repair at Tenant's own cost
and expense, in default of which Landlord may cause such meter and equipment
replaced or repaired and collect the cost thereof from Tenant. Tenant agrees to
pay for water consumed, as shown on said meter, as and when bills are rendered,
and on default in making such payment, Landlord may pay such charges and collect
the same from Tenant. Any such costs or expenses incurred, or payments made by
Landlord for any of the reasons or purposes hereinabove stated shall be deemed
to be additional rent payable by Tenant and collectible by Landlord as such.

    (e) Provide janitorial service to the Premises five days a week, provided
the same are kept reasonably in order by Tenant, and if to be kept clean by
Tenant, no one other than persons approved by Landlord shall be permitted to
enter the Premises for such purposes. If the Premises are  not used exclusively
as offices, they shall be kept clean and in order by Tenant, at Tenant's
expense, and to the satisfaction of Landlord, and by persons approved by
Landlord. Tenant shall pay to Landlord the cost of removal of any of Tenant's
refuse and rubbish, to the extent that the same exceeds the refuse and rubbish
usually attendant upon the use of the Premises as offices.

    Landlord reserves the right to stop service of the elevator, plumbing, 
ventilation, air conditioning, and electric systems, when necessary, by 
reason of accident or emergency or for repairs, alterations or improvements, 
in the judgment of Landlord desirable or necessary to be made, until said 
repairs, alterations or improvements shall have been completed, and shall 
further have no responsibility or liability for failure to supply elevator 
facilities, plumbing, ventilating, air conditioning, or electric service, 
when prevented from so doing by strike or accident or by any cause beyond 
Landlord's reasonable control, or by 

<PAGE>

laws, rules, orders, ordinances, directions, regulations, or requirements of 
any federal, state, county, or municipal authority or failure of gas, oil, or 
other suitable fuel supply or inability by exercise of reasonable diligence 
to obtain gas, oil, or other suitable fuel. It is expressly understood and 
agreed that any covenants on Landlord's part to furnish any service pursuant 
to any of the terms, covenants, conditions, provisions, or agreements of this 
Lease, or to perform any act or thing for the benefit of Tenant, shall not be 
deemed breached if Landlord is unable to furnish or perform the same by 
virtue of a strike or labor trouble or any other cause whatsoever beyond 
Landlord's control.

to Tenant's business invitee. Landlord shall in all cases retain the right to 
control and prevent access thereto of all persons whose presence in the 
judgment of Landlord would be prejudicial to the safety, character, 
reputation, and interest of the building and its tenants; provided that 
nothing herein contained shall be construed to prevent such access to persons 
with whom any tenant normally deals in the ordinary course of its business, 
unless such persons are engaged in illegal or unlawful activities. No tenant 
and no employee or invitee of any tenant shall go upon the roof of the 
building.

their installation.

    8. The building freight elevator(s) shall be available for use by all
tenants in the building, subject to such reasonable scheduling as Landlord, in

hours of 6:00 p.m. and 6:00 a.m. or on Saturday or Sunday. Deliveries during
normal office hours shall be limited to normal office supplies and other small
items. No deliveries shall be made which impede or interfere with other tenants
or the operation of the building.

    9. Tenant shall not place a load upon any floor of the Premises which
exceeds the load per square foot which such floor was designed to carry and
which is allowed by law. Landlord shall have the right to prescribe the weight,
size, and position of all equipment, materials, furniture, or other property
brought into the building. Heavy objects shall, if considered necessary by
Landlord, stand on such platforms as determined by Landlord to be necessary to
properly distribute the weight, which platforms shall be provided at Tenant's
expense. Business machines and mechanical equipment belonging to Tenant, which
cause noise or vibration that may be transmitted to the structure of the
building or to any space therein to such a degree as to be objectionable to
Landlord or to any tenants in the building, shall be placed and maintained by
Tenant, at Tenant's expense, on vibration eliminators or other devices 
sufficient to eliminate noise or vibration. The persons employed to move such
equipment in or out of the building must be acceptable to Landlord. Landlord
will not be responsible for loss of, or damage to, any such equipment or other
property from any cause, and all damage done to the building by maintaining or
moving such equipment or other property shall be repaired at the expense of
Tenant.

3.  COMPENSATION AND ROYALTIES

    3.1  Agreement for Royalties. AYURCORE agrees to pay ROSENBERG a royalty at
         the following rates:

<PAGE>


         (1)  A rate of [***] of all Net Receipts from Transfers of Products to
              be used in, or which are imported into, any Patent Jurisdiction 
              by or on behalf of AYURCORE.

         (2)  A rate of [***] of all Net Royalties received or earned by 
              AYURCORE from sublicensees.

    3.2  Payment. The royalty on the Transfer of each Product is earned on the
         earlier of (l) the day on which the Product is shipped to a
         distributor or customer, or (2) the day on which an invoice issues for
         the Product. Each royalty payment to ROSENBERG must be paid within 30
         days after the end of the calendar quarter in which the royalty is
         earned. Royalties earned on Products for which refunds, credits, or
         allowances are given or made by AYURCORE or its sublicensees shall be
         credited against future royalties due to ROSENBERG, Royalties shall be
         paid in U S dollars. For those Transfers of Products made by AYURCORE
         in other currencies, the Net Receipts shall be  converted to U.S.
         dollars in accordance with the exchange rates published in the Wall
         Street Journal at the end of the respective royalty period.

    3.3  Statements. With each royalty payment, AYURCORE must submit to
         ROSENBERG a statement of. (1) the number of Transfers of Products from
         all sources during the applicable period, (2) the total of the Net
         Receipts during the applicable period, and (3) a clear computation of
         the royalty payment.

    3.4  Inspection. AYURCORE agrees to keep or have kept separate and 
         adequately detailed accounting records of all Transfers of Products.
         Such accounting records shall be kept for a minimum of 2 years. During
         the term of this Agreement and for one year thereafter, ROSENBERG or
         its agents have the right to inspect the relevant accounting records
         of AYURCORE to verify the accuracy of the royalties paid or payable to
         ROSENBERG. All inspected information shall be kept in confidence from
         third parties. ROSENBERG must give at least 10 days' written notice to
         AYURCORE before any inspection, and may not inspect more than once in
         any 12 month period. All inspections must be during ordinary business
         hours, and shall be conducted so as to not unreasonably interfere with
         AYURCORE's normal business activities. If any inspection discloses
         that the amount of royalties paid by AYURCORE is incorrect in either
         ROSENBERG's or AYURCORE's favor, then any amount due to either Party
         must be paid within 30 days by the other Party. If ROSENBERG's
         inspection demonstrates that the royalties paid for the period in
         question are less than 95% of the correct amount owing, AYURCORE shall
         be liable for ROSENBERG's cost of inspection. Otherwise, ROSENBERG
         must pay all of ROSENBERG's costs for any inspection.

    3.5  Credit for Expenses. Any expenses incurred by AYURCORE to obtain
         patent protection for the Assigned Rights, from preparation of an
         application through response to the first substantive office action
         (i.e., excluding a restriction 

* Confidential provisions omitted and filed separately with the Commission.

         requirement), shall be credited against future royalties owed by
         AYURCORE to ROSENBERG. In addition, any expenses incurred by AYURCORE
         to obtain regulatory approval of any Product shall be credited against
         future royalties owed by AYURCORE to ROSENBERG.

                               STOCK PURCHASE AGREEMENT


    STOCK PURCHASE AGREEMENT made as of the 31st day of October, 1997, 
between AyurCore Inc., a Delaware corporation, whose principal offices are 
located at 1737 N. First Street, Suite 290, San Jose, California 95112 (the 
"Company"), and Fred Kassner (the "Purchaser").

    WHEREAS, the Company desires to issue and sell to the Purchaser, and the 
Purchaser desires to purchase from the Company, that number of shares set 
forth on the signature page hereto (the "Shares") of the Company's Common 
Stock, $.001 par value per share (the "Common Stock"), on the terms and 
conditions hereinafter set forth.

    NOW, THEREFORE, for and in consideration of the premises and the mutual 
covenants hereinafter set forth, the parties hereto do hereby agree as 
follows:

I.  AGREEMENT OF PURCHASE AND SALE

    1.1  Subject to the terms and conditions hereinafter set forth, the 
Purchaser agrees to purchase the Shares from the Company and the Company 
agrees to issue and sell the Shares to the Purchaser.

    1.2  The purchase price for the Shares shall be $4.00 per Share and shall 
be paid by the tender to the Company for cancellation of all principal and 
accrued interest owing to the Purchaser under the Company's (i) Convertible 
Promissory Note, dated October 14, 1994, and (ii) Promissory Note, dated 
April 4, 1996 (such notes, copies of which are attached hereto as Exhibit A 
and Exhibit B, respectively, the "Notes") owned by the Purchaser.

    1.3  Simultaneously with the execution of this Agreement, the Purchaser 
is delivering the Notes to the law firm of Rubin Baum Levin Constant & 
Friedman to be held in escrow pending an amendment to the Company's charter 
(i) reclassifying the Company's Class A and Class B common stock into one 
class of common stock and (ii) increasing the number of authorized but 
unissued shares of common stock to make available a sufficient number of 
shares for the issuance of the Shares contemplated hereby (the "Charter 
Amendment").  Effectiveness of the Charter Amendment shall be deemed a 
condition precedent to the purchase and sale of the Shares contemplated 
hereby.

    1.4  The Purchaser hereby authorizes and directs the Company to deliver 
the Shares to be issued to the Purchaser pursuant to this Agreement to the 
address set forth on the signature page hereto.


<PAGE>

    1.5  The Purchaser understands that the Company reserves the right to 
reject the purchase of  the Shares hereunder if any of the Purchaser's 
representations contained herein shall prove to be untrue.

II. REPRESENTATIONS BY THE PURCHASER

    2.1  The Purchaser recognizes that an investment in the Company is highly 
speculative and subject to a high degree of risk.  The Purchaser understands 
that the Company is in need of immediate substantial additional financing in 
order to meet its business objectives.  The Purchaser understands that if the 
Company is not able to obtain additional financing, the Company will not be 
able to conduct its operations and Purchaser will in all likelihood lose a 
substantial portion or all of the Purchaser's investment.  The Purchaser 
acknowledges that the Company is in the development stage and has not 
conducted any significant operations to date or received any meaningful 
operating revenues and expects to incur operating losses for the foreseeable 
future.  The Purchaser acknowledges that there is no assurance that the 
Company will ever achieve meaningful revenues or profitable operations.  The 
Purchaser is aware of the problems, delays, expenses and difficulties 
encountered by an enterprise in the Company's stage of development, many of 
which may be beyond the Company's control.  These include, but are not 
limited to, unanticipated problems relating to product development, testing, 
regulatory compliance, manufacturing costs, production and marketing 
problems, additional costs and expenses that may exceed current estimates and 
competition.

    2.2  The Purchaser acknowledges that the Purchaser must be a qualified 
investor, as described herein, to qualify for the purchase of the Shares, and 
that the Purchaser must be able to bear the economic risk of this investment.

    2.3  The Purchaser represents that the Purchaser is an "accredited 
investor" as such term is defined in Rule 501 of Regulation D promulgated 
under the Shares Act of 1933, as amended (the "Act").

    2.4  The Purchaser acknowledges that the Purchaser has prior investment 
experience, including investment in non-listed and non-registered securities, 
or the Purchaser has employed the services of an investment advisor, attorney 
or accountant to read all of the documents furnished or made available by the 
Company to the Purchaser and to evaluate the merits and risks of such an 
investment on the Purchaser's behalf; that the Purchaser recognizes the 
highly speculative nature of this investment; and is able to bear the 
economic risk the Purchaser hereby assumes.

    2.5  The Purchaser represents that the Purchaser has been furnished by 
the Company during the course of this transaction with 


<PAGE>

all information regarding the Company which the Purchaser had requested or 
desired to know; that all documents which could be reasonably provided have 
been made available for the Purchaser's inspection and review; that the 
Purchaser has been afforded the opportunity to ask questions of and receive 
answers from duly authorized officers or other representatives of the Company 
concerning the terms and conditions of the investment, and any additional 
information which the Purchaser had requested; and that the Company has made 
no representations concerning the Company except as set forth herein.

    2.6  The Purchaser acknowledges that this transaction has not been 
reviewed by the Securities and Exchange Commission ("SEC") and is intended to 
be exempt from the registration requirements of the Act.  The Purchaser 
represents that the Shares being purchased hereunder are being purchased for 
the Purchaser's own account, for investment and not for distribution or 
resale to others.  The Purchaser agrees that the Purchaser will not sell or 
otherwise transfer such securities or any interest in such securities unless 
they are registered under the Act or unless an exemption from such 
registration is available.  The Purchaser further agrees that notwithstanding 
the availability, if any, of any such exemption, the Purchaser will not sell 
or otherwise transfer the Shares or any interest in the Shares except in 
compliance with all of the provisions and conditions of Rule 144 promulgated 
under the Act as if such Rule were applicable.

    2.7  The Purchaser consents that the Company may, if it desires, permit 
the transfer of the Shares received out of the Purchaser's name only when the 
Purchaser's request for transfer is accompanied by an opinion of counsel 
reasonably satisfactory to the Company that neither the sale nor the proposed 
transfer results in a violation of the Act or any applicable state "blue sky" 
laws (collectively "Securities Laws").  

    2.8  The Purchaser agrees to hold the Company and its directors, officers 
and controlling persons and their respective heirs, representatives, 
successors and assigns harmless and to indemnify them against all 
liabilities, costs and expenses incurred by them as a result of any 
misrepresentation made by him contained herein or in the Confidential 
Purchaser Questionnaire or any sale or distribution by the undersigned 
Purchaser in violation of any Securities Laws.

    2.9  The Purchaser consents to such restrictions on transferability and 
sale of the Shares as may be requested by a managing underwriter in 
connection with an initial public offering of the Company's equity securities 
(an "IPO"), which restrictions may include, by way of example, a twelve month 
lock-up period following consummation of an initial public offering.
 
    2.10 The Purchaser consents to the placement of a legend on 


<PAGE>

any certificate or other document evidencing the Shares stating that they 
have not been registered under the Act and setting forth or referring to the 
restrictions on transferability and sale thereof.  The Purchaser is aware 
that the Company will make a notation in its records with respect to the 
restrictions on the transferability of such securities.

III.     REPRESENTATIONS BY THE COMPANY

    3.1  The Company represents and warrants to the Purchaser that prior to 
the consummation of this purchase and at such date:

         (a)  The Company is a corporation duly organized, existing and in

all material respects complying therewith.

         (e)  The Company knows of no pending or threatened legal or 
governmental proceedings to which the Company is a party which could 
materially adversely affect the business, property, financial condition or 
operations of the Company.

         (f)  The Company is not in violation of or default under, nor will 
the execution and delivery of this Agreement, the issuance of the Shares and 
the incurrence of the obligations herein and therein set forth and the 
consummation of the transactions herein or therein contemplated, result in a 
violation of, or constitute a default under, the certificate of incorporation 
or by-laws, in the performance or observance of any material obligations, 
agreement, covenant or condition contained in any bond, debenture, note or 
other evidence of indebtedness to which the Company is a party or by which it 
or any of its properties may be bound or in violation of any material order, 
rule, regulations writ, injunction, or decree of any government, governmental 
instrumentality or court, domestic or foreign.  The Company represents that 
presently it does 


<PAGE>

not have a sufficient number of authorized but unissued shares of common 
stock available for the issuance of the Shares contemplated hereby.  The 
Company agrees to use its best efforts to cause the Charter Amendment to 
become effective.

                               STOCK PURCHASE AGREEMENT


    STOCK PURCHASE AGREEMENT made as of the 31st day of October, 1997, between
AyurCore Inc., a Delaware corporation, whose principal offices are located at
1737 N. First Street, Suite 290, San Jose, California 95112 (the "Company"), and
Michael R. Splinter and Patricia Robestoff (together, the "Purchaser").

    WHEREAS, the Company desires to issue and sell to the Purchaser, and the
Purchaser desires to purchase from the Company, that number of shares set forth
on the signature page hereto (the "Shares") of the Company's Common Stock, $.001
par value per share (the "Common Stock"), on the terms and conditions
hereinafter set forth.

    NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto do hereby agree as follows:

I.  AGREEMENT OF PURCHASE AND SALE

    1.1  Subject to the terms and conditions hereinafter set forth, the
Purchaser agrees to purchase the Shares from the Company and the Company agrees
to issue and sell the Shares to the Purchaser.

    1.2  The purchase price for the Shares shall be $4.00 per Share and shall
be paid by the tender to the Company for cancellation of all principal and
accrued interest owing to the Purchaser under the Company's (i) Promissory Note,
dated March 22, 1996, and (ii) Promissory Note, dated August 12, 1997 (such
notes, copies of which are attached hereto as Exhibit A and Exhibit B,
respectively, the "Notes") owned by the Purchaser.

    1.3  Simultaneously with the execution of this Agreement, the Purchaser is
delivering the Notes to the law firm of Rubin Baum Levin Constant & Friedman to
be held in escrow pending an amendment to the Company's charter (i)
reclassifying the Company's Class A and Class B common stock into one class of
common stock and (ii) increasing the number of authorized but unissued shares of
common stock to make available a sufficient number of shares for the issuance of
the Shares contemplated hereby (the "Charter Amendment").  Effectiveness of the
Charter Amendment shall be deemed a condition precedent to the purchase and sale
of the Shares contemplated hereby.

    1.4  The Purchaser hereby authorizes and directs the Company to deliver the
Shares to be issued to the Purchaser pursuant to this Agreement to the address
set forth on the signature page hereto.

<PAGE>

    1.5  The Purchaser understands that the Company reserves the right to
reject the purchase of  the Shares hereunder if any of the Purchaser's
representations contained herein shall prove to be untrue.

II. REPRESENTATIONS BY THE PURCHASER

    2.1  The Purchaser recognizes that an investment in the Company is highly
speculative and subject to a high degree of risk.  The Purchaser understands
that the Company is in need of immediate substantial additional financing in
order to meet its business objectives.  The Purchaser understands that if the
Company is not able to obtain additional financing, the Company will not be able
to conduct its operations and Purchaser will in all likelihood lose a
substantial portion or all of the Purchaser's investment.  The Purchaser
acknowledges that the Company is in the development stage and has not conducted
any significant operations to date or received any meaningful operating revenues
and expects to incur operating losses for the foreseeable future.  The Purchaser
acknowledges that there is no assurance that the Company will ever achieve
meaningful revenues or profitable operations.  The Purchaser is aware of the
problems, delays, expenses and difficulties encountered by an enterprise in the
Company's stage of development, many of which may be beyond the Company's
control.  These include, but are not limited to, unanticipated problems relating
to product development, testing, regulatory compliance, manufacturing costs,
production and marketing problems, additional costs and expenses that may exceed
current estimates and competition.

    2.2  The Purchaser acknowledges that the Purchaser must be a qualified
investor, as described herein, to qualify for the purchase of the Shares, and
that the Purchaser must be able to bear the economic risk of this investment.

    2.3  The Purchaser represents that the Purchaser is an "accredited
investor" as such term is defined in Rule 501 of Regulation D promulgated under
the Shares Act of 1933, as amended (the "Act").

    2.4  The Purchaser acknowledges that the Purchaser has prior investment
experience, including investment in non-listed and non-registered securities, or
the Purchaser has employed the services of an investment advisor, attorney or
accountant to read all of the documents furnished or made available by the
Company to the Purchaser and to evaluate the merits and risks of such an
investment on the Purchaser's behalf; that the Purchaser recognizes the highly
speculative nature of this investment; and is able to bear the economic risk the
Purchaser hereby assumes.

    2.5  The Purchaser represents that the Purchaser has been furnished by the
Company during the course of this transaction with 

<PAGE>

all information regarding the Company which the Purchaser had requested or
desired to know; that all documents which could be reasonably provided have been
made available for the Purchaser's inspection and review; that the Purchaser has
been afforded the opportunity to ask questions of and receive answers from duly
authorized officers or other representatives of the Company concerning the terms
and conditions of the investment, and any additional information which the
Purchaser had requested; and that the Company has made no representations
concerning the Company except as set forth herein.

    2.6  The Purchaser acknowledges that this transaction has not been reviewed
by the Securities and Exchange Commission ("SEC") and is intended to be exempt
from the registration requirements of the Act.  The Purchaser represents that
the Shares being purchased hereunder are being purchased for the Purchaser's own
account, for investment and not for distribution or resale to others.  The
Purchaser agrees that the Purchaser will not sell or otherwise transfer such
securities or any interest in such securities unless they are registered under
the Act or unless an exemption from such registration is available.  The
Purchaser further agrees that notwithstanding the availability, if any, of any
such exemption, the Purchaser will not sell or otherwise transfer the Shares or
any interest in the Shares except in compliance with all of the provisions and
conditions of Rule 144 promulgated under the Act as if such Rule were
applicable.

    2.7  The Purchaser consents that the Company may, if it desires, permit the
transfer of the Shares received out of the Purchaser's name only when the
Purchaser's request for transfer is accompanied by an opinion of counsel
reasonably satisfactory to the Company that neither the sale nor the proposed
transfer results in a violation of the Act or any applicable state "blue sky"
laws (collectively "Securities Laws").  

    2.8  The Purchaser agrees to hold the Company and its directors, officers
and controlling persons and their respective heirs, representatives, successors
and assigns harmless and to indemnify them against all liabilities, costs and
expenses incurred by them as a result of any misrepresentation made by him
contained herein or in the Confidential Purchaser Questionnaire or any sale or
distribution by the undersigned Purchaser in violation of any Securities Laws.

    2.9  The Purchaser consents to such restrictions on transferability and
sale of the Shares as may be requested by a managing underwriter in connection
with an initial public offering of the Company's equity securities (an "IPO"),
which restrictions may include, by way of example, a twelve month lock-up period
following consummation of an initial public offering.
 
    2.10 The Purchaser consents to the placement of a legend on 

<PAGE>


any certificate or other document evidencing the Shares stating that they have
not been registered under the Act and setting forth or referring to the
restrictions on transferability and sale thereof.  The Purchaser is aware that
the Company will make a notation in its records with respect to the restrictions
on the transferability of such securities.

III.     REPRESENTATIONS BY THE COMPANY

    3.1  The Company represents and warrants to the Purchaser that prior to the
consummation of this purchase and at such date:

         (a)  The Company is a corporation duly organized, existing and in good

respects complying therewith.

         (e)  The Company knows of no pending or threatened legal or
governmental proceedings to which the Company is a party which could materially
adversely affect the business, property, financial condition or operations of
the Company.

         (f)  The Company is not in violation of or default under, nor will the
execution and delivery of this Agreement, the issuance of the Shares and the
incurrence of the obligations herein and therein set forth and the consummation
of the transactions herein or therein contemplated, result in a violation of, or
constitute a default under, the certificate of incorporation or by-laws, in the
performance or observance of any material obligations, agreement, covenant or
condition contained in any bond, debenture, note or other evidence of
indebtedness to which the Company is a party or by which it or any of its
properties may be bound or in violation of any material order, rule, regulations
writ, injunction, or decree of any government, governmental instrumentality or
court, domestic or foreign.  The Company represents that presently it does 

<PAGE>

not have a sufficient number of authorized but unissued shares of common stock
available for the issuance of the Shares contemplated hereby.  The Company
agrees to use its best efforts to cause the Charter Amendment to become
effective.

AyurCore, Inc.
1737 N. First Street
Suite 290
San Jose, California  95112

Attention:  Deepa Chitre, M.D., President & CEO

Dear Dr. Chitre:

         This will confirm the arrangements, terms and conditions pursuant to 
which LT Lawrence & Co., Inc. (the "Consultant"), has been retained to serve 
as a financial consultant and advisor to AyurCore, Inc., a Delaware 
corporation (the "Company"), on a non-exclusive basis for a period of two (2) 
years commencing on _________, 1998 [the Closing Date].  The undersigned 
hereby agrees to the following terms and conditions:

          1.  Duties of Consultant.  Consultant shall, at the request of the 
Company, upon reasonable notice, render the following services to the Company 
from time to time.

              (a)  Consulting Services.  Consultant will provide financial 
consulting services and advice pertaining to the Company's business affairs 
as the Company may from time to time reasonably request.  Without limiting 
the generality of the foregoing, Consultant will assist the Company in 
developing, studying and evaluating financing and merger and acquisition 
proposals based upon documentary information provided to the Consultant by 
the Company.

              (b)  Financing.  Consultant will assist and represent the 
Company in obtaining both short and long-term financing.  The Consultant will 
be entitled to additional compensation under certain circumstances in 
accordance with the terms set forth in Section 3 hereof.

              (c)  Wall Street Liaison.  Consultant will, when appropriate, 
arrange meetings between representatives of the Company and individuals and 
financial institutions in the investment community, such as security 
analysts, portfolio managers and market makers.

         The services described in this Section 1 shall be rendered by 
Consultant without any direct supervision by the Company and at such time and 
place and in such manner (whether by conference, telephone, letter or 
otherwise) as Consultant may determine.

                                           
<PAGE>


         2.   Compensation.  As compensation for Consultant's services 
hereunder, the Company shall pay to Consultant an annual fee of Fifteen 
Thousand Dollars ($15,000), the entire Thirty Thousand Dollars ($30,000) 
payable in full, in advance, on ____________ __, 1998.

          3.   Additional Compensation in Certain Circumstances.  In addition 
to the financial consulting services described in Section 1 above, Consultant 
may bring the Company in contact with persons, whether individuals or 
entities, that may be suitable candidates to purchase substantially all of 
the stock or assets of the Company, to have substantially all of its stock or 
assets purchased by the Company or merge with the Company.  If, at any time 
up until the second anniversary of the date hereof, the Company enters into 
an agreement with any such persons or their affiliates, or with any persons 
introduced to the Company by any such persons or their affiliates, pursuant 
to which substantially all of the Company's stock or assets is purchased or 
the Company purchases substantially all of the stock or assets of another 
entity or the Company is merged with or into another entity (each 
"Transaction"), the Company will pay to Consultant, in accordance with the 
formula set forth below, additional compensation based on the aggregate value 
of the consideration, whether in cash, securities, assumption of (or purchase 
subject to) debt or liabilities (including, without limitation, indebtedness 
for borrowed money, pension liabilities and guarantees), or other property, 
obligations or services, paid or payable directly or indirectly (in escrow or 
otherwise) or otherwise assumed in connection with such Transaction (the 
"Consideration").  For purposes of this Section 3, the "Company" shall 
include its subsidiaries and any other entity in which it owns (directly or 
indirectly) a majority interest.

         The additional compensation to be paid will be paid upon the closing 
of the Transaction (except that, if any part of the Consideration is in the 
form of contingent payments to be calculated to reference to uncertain future 
occurrences, such as future financial or business performance, then the 
portion of the fees of Consultant relating to such part of the Consideration 
shall be payable at the earlier of (i) the receipt or payment of such 
Consideration; or (ii) the time that the amount of such Consideration can be 
determined) by certificate check, in the following amounts:

              5% of the first $5,000,000 of the Consideration;

              4% of the Consideration in excess of $5,000,000 and up to
              $6,000,000;

              3% of the Consideration in excess of $6,000,000 and up to
              $7,000,000;


                                         -2-
<PAGE>



              2% of the Consideration in excess of $7,000,000 and up to
              $8,000,000; and

              1% of any Consideration in excess of $8,000,000.

          4.   Available Time.  Consultant shall make available such time as 
it, in its sole discretion, shall deem appropriate for the performance of its 
obligations under this agreement and may in certain circumstances be entitled 
to additional compensation in connection therewith.

          5.   Relationship.  Nothing herein shall constitute Consultant as 
an employee or agent of the Company, except to such extent as might 
hereinafter be agreed upon for a particular purpose.  Except as might 
hereinafter be expressly agreed, Consultant shall not have the authority to 
obligate or commit the Company in any manner whatsoever.

          6.   Confidentiality.  Except in the course of the performance of 
its duties hereunder, Consultant agrees that it shall not disclose any trade 
secrets, know-how, or other proprietary information not in the public domain 
learned as a result of this Agreement unless and until such information 
becomes generally known.

          7.   Assignment and Termination.  This Agreement shall not be 
assignable by any party except to successors to all or substantially all of 
the business of either party for any reason whatsoever without the prior 
written consent of the other party, which consent may be arbitrarily withheld 
by the party whose consent is required.

          8.   Governing Law.  This Agreement shall be deemed to be a

shall be construed in accordance with the laws of said State.

represented by this Warrant may be exercised by the holder hereof, in whole or
in part, by the surrender of this Warrant (with the notice of exercise form
attached hereto as EXHIBIT 1 duly executed) at the principal office of the
Company and by the payment to the Company, by check or wire transfer, of an
amount equal to the then applicable Warrant Price per share multiplied by the
number of shares then being purchased.  The Company agrees that the shares so
purchased shall be deemed to be issued to the holder hereof as the record owner
of such shares as of the close of business on the date on which this Warrant
shall have been surrendered and payment made for such shares as 

<PAGE>

aforesaid.  In the event of any exercise of this Warrant, certificates for the
shares of stock so purchased shall be delivered to the holder hereof within 15
days thereafter and, unless this Warrant has been fully exercised or expired, a
new Warrant representing the portion of the shares, if any, with respect to
which this Warrant shall not then have been exercised, shall also be issued to
the holder hereof within such 15 day period.

         (b)  CONVERSION.  Subject to Section 1 hereof, the Holder may convert
this Warrant (the "CONVERSION RIGHT"), in whole or in part, into the number of
shares of Common Stock of the Company calculated pursuant to the following
formula by surrendering this Warrant (with the notice of exercise form attached
hereto as EXHIBIT 1 duly executed) at the principal office of the Company
specifying the number of shares of Common Stock of the Company, the rights to
purchase which the Holder desires to convert:  


                             X    =    Y (A - B)
                                       ---------
                                          A

    where:    X    =    the number of shares of Common Stock to be issued to
                        the Holder; 

              Y    =    the number of shares of Common Stock subject to this
                        Warrant for which the Conversion Right is being
                        exercised; 

              A    =    the fair market value of one share of Common Stock; 

              B    =    the Warrant Price.

    As used herein, the fair market value of a share of Common Stock shall
mean, with respect to each share of Common Stock, the closing price per share of
the Company's Common Stock on the principal national securities exchange on
which the Common Stock is then listed or admitted to trading or, if not then
listed or admitted to trading on any such exchange, on the NASDAQ National
Market System, or if not then listed or traded on any such exchange or system,
the last sale price per share on NASDAQ Small-Cap Market.  The Company agrees
that the shares so converted shall be deemed to be issued to the holder hereof
as the record owner of such shares as of the close of business on the date on
which this Warrant shall have been surrendered as aforesaid.  In the event of
any conversion of this Warrant, certificates for the shares of stock so
converted shall be delivered to the holder hereof within 15 days thereafter and,
unless this Warrant has been fully converted or expired, a new Warrant
representing the portion of the shares, if any, with respect to which this
Warrant shall not then have been converted, shall also be issued to the holder
hereof within such 15 day period.

    4.   STOCK FULLY PAID; RESERVATION OF SHARES.  All Common Stock which may
be issued upon the exercise or conversion of this Warrant will, upon issuance,
be fully paid and nonassessable, and free from all taxes, liens and charges with
respect to the issue thereof.  During 

                                        - 2 -
<PAGE>

the period within which the rights represented by this Warrant may be exercised,
the Company will at all times have authorized, and reserved for the purpose of
the issuance upon exercise of the purchase rights evidenced by this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of
the rights represented by this Warrant.

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The kind of
securities purchasable upon the exercise of this Warrant, the Warrant Price and
the number of shares purchasable upon exercise of this Warrant shall be subject
to adjustment from time to time upon the occurrence of certain events as
follows:

         (a)  RECLASSIFICATION, CONSOLIDATION OR MERGER.  In case of any
reclassification or change of outstanding securities of the class issuable upon
exercise of this Warrant (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination), or in case of any consolidation or merger of the Company with
or into another corporation, other than a merger with another corporation in
which the Company is a continuing corporation and which does not result in any
reclassification or change of outstanding securities issuable upon exercise of
this Warrant, or in case of any sale of all or substantially all of the assets
of the Company, the Company, or such successor or purchasing corporation, as the
case may be, shall execute a new Warrant, providing that the holder of this
Warrant shall have the right to exercise such new Warrant and procure upon such
exercise, in lieu of each share of Common Stock theretofore issuable upon
exercise of this Warrant, the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
consolidation, or merger by a holder of one share of Common Stock.  Such new
Warrant shall provide for adjustments which shall be as nearly equivalent as may
be practicable to the adjustments provided for in this Section 5.  No
consolidation or merger of the Company with or into another corporation referred
to in the first sentence of this paragraph (b) shall be consummated unless the
successor or purchasing corporation referred to above shall have agreed to issue
a new Warrant as provided in this Section 5.  The provisions of this subsection
(b) shall similarly apply to successive reclassification, changes,
consolidations, mergers and transfers.

         (b)  SUBDIVISION OR COMBINATION OF SHARES.  If the Company at any time
while this Warrant remains outstanding and unexpired shall subdivide or combine
its Common Stock, the Warrant Price shall be proportionately decreased in the
case of a subdivision or increased in the case of a combination.

         (c)  STOCK DIVIDENDS.  If the Company at any time while this Warrant
is outstanding and unexpired shall pay a dividend with respect to Common Stock
payable in, or make any other distribution with respect to, Common Stock (except
any distribution specifically provided for in the foregoing subparagraphs (a) or
(b)) then the Warrant Price shall be adjusted, from and after the date of
determination of shareholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Warrant Price in effect immediately
prior to such date of determination by a fraction (x) the numerator of which
shall be the total number of shares of Common Stock outstanding immediately
prior to such dividend or distribution and (y) 

                                        - 3 -
<PAGE>

the denominator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend or distribution.

         (d)  ADJUSTMENT OF NUMBER OF SHARES.  Upon each adjustment in the
Warrant Price pursuant to any of Sections 5 (a) through (c), the number of
shares of Common Stock purchasable hereunder shall be adjusted, to the nearest
whole share, to the product obtained by multiplying the number of shares
purchasable immediately prior to such adjustment in the Warrant Price by a
fraction, the numerator of which shall be the Warrant Price immediately prior to
such adjustment and the denominator of which shall be the Warrant Price
immediately thereafter.

    6.   NOTICE OF ADJUSTMENTS.  Whenever any Warrant Price shall be adjusted
pursuant to Section 5 hereof, the Company shall prepare a certificate signed by
its chief financial officer setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated, the Warrant Price after giving effect to such
adjustment and the number of shares then purchasable upon exercise of this
Warrant, and shall cause copies of such certificate to be mailed (by first class
mail, postage prepaid) to the holder of this Warrant at the address specified in
Section 11(d) hereof, or at such other address as may be provided to the Company
in writing by the holder of this Warrant.

    7.   FRACTIONAL SHARES.  No fractional shares of Common Stock will be
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Warrant Price then in effect.

    8.   COMPLIANCE WITH THE ACT.

         (a)  COMPLIANCE WITH THE ACT.  The holder of this Warrant, by
acceptance hereof, agrees that this Warrant and the shares of Common Stock to be
issued upon exercise hereof are being acquired for investment for such holder's
own account and not with a view toward distribution thereof, and that it will
not offer, sell or otherwise dispose of this Warrant or any shares of Common
Stock to be issued upon exercise hereof unless this Warrant has been registered
under the Act and applicable state securities laws or (i) registration under
applicable state securities laws is not required and (ii) an opinion of counsel
satisfactory to the Company is furnished to the Company to the effect that
registration under the Act is not required.

    9.   TRANSFER AND EXCHANGE OF WARRANT.

         (a)  TRANSFER.  This Warrant may be transferred or succeeded to by any
person who is (i) an affiliate within the meaning of Rule 144 of the Securities
Act of 1933, as amended or (ii) a partner, shareholder, member or other equity
holder of such Holder; PROVIDED HOWEVER, that the Company is given written
notice by the transferee at the time of such transfer stating the name and
address of the transferee and identifying the securities with respect to which
such rights are being assigned.  Additionally, with the prior consent of the
Company, which consent shall not be unreasonably withheld, this Warrant may be
transferred or sold to any other person PROVIDED, 

                                        - 4 -
<PAGE>

HOWEVER, that the Company is given written notice by the transferee at the time
of such transfer stating the name and address of the transferee and identifying
the securities with respect to which such rights are being assigned.

         (b)  EXCHANGE.  Subject to compliance with the terms hereof, this
Warrant and all rights hereunder are transferable, in whole or in part, at the
office of the Company by the holder hereof in person or by duly authorized
attorney, upon surrender of this Warrant properly endorsed.  Each taker and
holder of this Warrant, by taking or holding the same, consents and agrees that
this Warrant, when endorsed in blank, shall be deemed negotiable; provided, that
the last holder of this Warrant as registered on the books of the Company may be
treated by the Company and all persons dealing with this Warrant as the absolute
owner hereof for any purposes and as the person entitled to exercise the rights
represented by this Warrant or to transfer hereof on the books of the Company,
any notice to the contrary notwithstanding, unless and until such holder seeks
to transfer registered ownership of this Warrant on the books of the Company and
such transfer is effected.

    10.  MISCELLANEOUS.

         (a)  REGISTRATION RIGHTS.  The registration of the securities granted
pursuant to any exercise hereunder are subject to a Registration Rights
Agreement, dated as of December 8, 1997, between the Company and 
_______________

         (b)  NO RIGHTS AS SHAREHOLDER.  No holder of this Warrant shall be
entitled to vote or receive dividends or be deemed the holder of Common Stock or
any other securities of the Company which may at any time be issuable on the
exercise hereof for any purpose, nor shall anything contained herein be
construed to confer upon the holder of this Warrant, as such, any of the rights
of a shareholder of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value or change of stock to no par value, consolidation, merger, conveyance or
otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until this Warrant shall have been exercised
and the shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.

         (c)  REPLACEMENT.  On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and,
in the case of loss, theft or destruction, on delivery of an indemnity
agreement, or bond reasonably satisfactory in form and amount to the Company or,
in the case of mutilation, on surrender and cancellation of this Warrant, the
Company, at its expense, will execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         (d)  NOTICE OF CAPITAL CHANGES.  In case:

                                        - 5 -
<PAGE>

              (i)     the Company shall declare any dividend or distribution
payable to the holders of its Common Stock;

              (ii)    there shall be any capital reorganization or

then, in any one or more of said cases, the Company shall give the holder of
this Warrant written notice, in the manner set forth in subparagraph (d) below,

or for determining shareholders entitled to vote upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up and of the date when any such transaction shall take place, as the
case may be.  Such written notice shall be given at least 15 days prior to the
transaction in question and not less than 5 days prior to the record date in
respect thereof.

         (e)  NOTICE.  Any notice given to either party under this Warrant
shall be in writing, and any notice hereunder shall be deemed to have been given

                                   December 8, 1997


To _____________________

Dear Sirs: 

    This will confirm that in consideration of your entering into the 
[Waiver Agreement, dated December 8, 1997 (in the case of Marathon Investments, 
LLC)/Stock Purchase Agreement dated as of October 31, 1997 (in the case of Fred 
Kassner)], between you and AyurCore, Inc., a Delaware corporation (the 
"Company") and the subsequent issuance to you of a certain Warrant Agreement 
exercisable for Common Stock (the "Warrant"), the Company covenants and agrees 
with you as follows: 

    1.   CERTAIN DEFINITIONS. As used in this Agreement, the following terms
shall have the following respective meanings: 

    "COMMISSION" shall mean the Securities and Exchange Commission, or any
other federal agency at the time administering the Securities Act. 

    "COMMON STOCK" shall mean the Common Stock, $.001 par value, of the
Company, as constituted as of the date of this Agreement. 

    "EXERCISE SHARES" shall mean shares of Common Stock issued upon exercise of
the Warrants. 

    "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934, as amended,
or any similar federal statute, and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time. 

    "REGISTRATION EXPENSES" shall mean the expenses so described in Section 6. 

    "RESTRICTED STOCK" shall mean the Exercise Shares, excluding Exercise
Shares which (a) have been registered under the Securities Act pursuant to an
effective registration statement filed thereunder and disposed of in accordance
with the registration statement covering them or (b) are eligible for sale
pursuant to Rule 144 under the Securities Act without regard to volume
limitations imposed by such Rule. 

    "SECURITIES ACT" shall mean the Securities Act of 1933, as amended, or any
similar federal statute, and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time. 

<PAGE>

    "SELLING EXPENSES" shall mean the expenses so described in Section 6. 

    2.   RESTRICTIVE LEGEND. Each certificate representing Exercise Shares
shall, except as otherwise provided in this Section 2 or in Section 3, be
stamped or otherwise imprinted with a legend substantially in the following
form: 

    "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND
MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN REGISTERED
UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE." 

A certificate shall not bear such legend if in the opinion of counsel
satisfactory to the Company the securities being sold thereby may be publicly
sold without registration under the Securities Act. 

    3.   NOTICE OF PROPOSED TRANSFER.  Prior to any proposed transfer of any
Warrant, the holder thereof shall give written notice to the Company of its
intention to effect such transfer. Each such notice shall describe the manner of
the proposed transfer and, if requested by the Company, shall be accompanied by
an opinion of counsel reasonably satisfactory to the Company to the effect that
the proposed transfer may be effected without registration under the Securities
Act, whereupon the holder of such Warrant shall be entitled to transfer such
Warrant in accordance with the terms of its notice.  Each certificate for
Exercise Shares granted under Warrants transferred as above provided shall bear
the legend set forth in Section 2, except that such certificate shall not bear
such legend if (i) such transfer is in accordance with the provisions of Rule
144 or Rule 144A (or any other rule permitting public sale without registration
under the Securities Act) or (ii) the opinion of counsel referred to above is to
the further effect that the transferee and any subsequent transferee (other than
an affiliate of the Company) would be entitled to transfer such securities in a
public sale without registration under the Securities Act. The restrictions
provided for in this Section 3 shall not apply to securities which are not
required to bear the legend prescribed by Section 2 in accordance with the
provisions of that Section.

    4.   INCIDENTAL REGISTRATION.  If at any time after twelve months from the
effective date of the Company's initial Registration Statement on Form SB-2, the
Company proposes to register any of its securities under the Securities Act for
sale to the public, whether for its own account or for the account of other
security holders or both (except with respect to registration statements on
Forms S-4, S-8 or another form not available for registering the Restricted
Stock for sale to the public), each such time it will give written notice to all
holders of outstanding Restricted Stock of its intention so to do. Upon the
written request of any such holder, received by the Company within 15 days after
the giving of any such notice by the Company, to register any of its Restricted
Stock (which request shall state the intended method of disposition thereof),
the Company will use its best efforts to cause the Restricted Stock as to which
registration shall have been so requested to be included in the securities to be
covered by the registration statement proposed to be filed by the Company, all
to the extent requisite to permit the sale or other disposition by the holder
(in accordance with its written request) of such Restricted Stock so registered.
In the event that any registration pursuant to this 

                                        - 2 -
<PAGE>

Section 4 shall be, in whole or in part, an underwritten public offering of
Common Stock, the number of shares of Restricted Stock to be included in such an
underwriting may be reduced if and to the extent that the managing underwriter
shall be of the opinion that such inclusion would adversely affect the marketing
of the securities to be sold by the Company therein, PROVIDED, HOWEVER, that any
such reduction in the number of shares of Restricted Stock included in such
underwriting shall be pro rata among all selling security holders requesting
inclusion therein.  Notwithstanding the foregoing provisions, the Company may
withdraw any registration statement referred to in this Section 4 without
thereby incurring any liability to the holders of Restricted Stock.

    5.   REGISTRATION PROCEDURES.  If and whenever the Company is required by
the provisions of Sections 4 to register any shares of Restricted Stock under
the Securities Act, the Company will, as expeditiously as possible:

         (a)  prepare and file with the Commission a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for the period of the
distribution contemplated thereby (determined as hereinafter provided); 

         (b)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above and comply with the provisions of
the Securities Act with respect to the disposition of all Restricted Stock
covered by such registration statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;
PROVIDED, HOWEVER, that the period during which the Company shall be required to
prepare and file amendments and supplements necessary to keep such registration
statement effective shall not continue beyond the first to occur of (i) the date
on which the Exercise Shares included therein are no long deemed Restricted
Stock or (ii) nine months from the date of the Prospectus. 

         (c)  furnish to each seller of Restricted Stock such number of copies
of the registration statement and the prospectus included therein (including
each preliminary prospectus) as such persons reasonably may request in order to
facilitate the public sale or other disposition of the Restricted Stock covered
by such registration statement; 

         (d)  use its best efforts to register or qualify the Restricted Stock
covered by such registration statement under the securities or "blue sky" laws
of such jurisdictions as the sellers of Restricted Stock or, in the case of an
underwritten public offering, the managing underwriter reasonably shall request,
PROVIDED, HOWEVER, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction; 

         (e)  use its best efforts to list the Restricted Stock covered by such
registration statement with any securities exchange on which the Common Stock of
the Company is then listed;

                                        - 3 -
<PAGE>

         (f)  promptly notify each seller of Restricted Stock under such
registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
of which the Company has knowledge as a result of which the prospectus contained
in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing; and

         (g)  make available for inspection by each seller of Restricted Stock,
all financial and other records, pertinent corporate documents and properties of
the Company, and cause the Company's officers, directors and employees to supply
all information reasonably requested by any such seller, in connection with such
registration statement. 

    In connection with each registration hereunder, the sellers of Restricted
Stock will furnish to the Company in writing such information with respect to
themselves and the proposed distribution by them as reasonably shall be
necessary in order to assure compliance with federal and applicable state
securities laws. 

    In connection with each registration pursuant to Sections 4 covering an
underwritten public offering, the Company and each seller agree to enter into a
written agreement with the managing underwriter selected in the manner herein
provided in such form and containing such provisions as are customary in the
securities business for such an arrangement between such underwriter and
companies of the Company's size and investment stature. 

    6.   EXPENSES.  All expenses incurred by the Company in complying with
Section 4, including, without limitation, all registration and filing fees,
printing expenses, fees and disbursements of counsel and independent public
accountants for the Company, fees and expenses (including counsel fees) incurred
in connection with complying with state securities or "blue sky" laws, fees of
the National Association of Securities Dealers, Inc., transfer taxes, fees of
transfer agents and registrars, costs of insurance, but excluding any Selling
Expenses, are called "Registration Expenses".  All underwriting discounts and
selling commissions applicable to the sale of Restricted Stock are called
"Selling Expenses".

    The Company will pay all Registration Expenses in connection with each
registration statement under Section 4. All Selling Expenses in connection with
each registration statement under Section 4 shall be borne by the participating
sellers in proportion to the number of shares sold by each, or by such
participating sellers other than the Company (except to the extent the Company
shall be a seller) as they may agree.

    7.   INDEMNIFICATION AND CONTRIBUTION. (a) In the event of a registration
of any of the Restricted Stock under the Securities Act pursuant to Section 4,
the Company will indemnify and hold harmless each seller of such Restricted
Stock thereunder, each underwriter of such Restricted Stock thereunder and each
other person, if any, who controls such seller or underwriter within the meaning
of the Securities Act, against any losses, claims, damages or liabilities, joint
or several, to 

                                        - 4 -
<PAGE>

which such seller, underwriter or controlling person may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Section 4, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such seller, each
such underwriter and each such controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, PROVIDED, HOWEVER,
that the Company will not be liable in any such case if and to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission so
made in conformity with information furnished by any such seller, any such
underwriter or any such controlling person in writing specifically for use in
such registration statement or prospectus.

         (b)  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Section 4, each seller of such Restricted
Stock thereunder, severally and not jointly, will indemnify and hold harmless
the Company, each person, if any, who controls the Company within the meaning of
the Securities Act, each officer of the Company who signs the registration
statement, each director of the Company, each underwriter and each person who
controls any underwriter within the meaning of the Securities Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such officer, director, underwriter or controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained
in the registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Section 4, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state,
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company and each such
officer, director, underwriter and controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, PROVIDED, HOWEVER,
that such seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information pertaining to
such seller, as such, furnished in writing to the Company by such seller
specifically for use in such registration statement or prospectus, and PROVIDED,
FURTHER, HOWEVER, that the liability of each seller hereunder shall be limited
to the proportion of any such loss, claim, damage, liability or expense which is
equal to the proportion that the public offering price of the shares sold by
such seller under such registration statement bears to the total public offering
price of all securities sold thereunder, but not in any event to exceed the
proceeds received by such seller from the sale of Restricted Stock covered by
such registration statement.

         (c)  Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 7 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 7 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel reasonably
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 7 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected, PROVIDED,
HOWEVER, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying party, the indemnified party shall have the
right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

         (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Restricted Stock exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 7 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 7 provides for
indemnification in such case, or, (ii) contribution under the Securities Act may
be required on the part of any such selling holder or any such controlling
person in circumstances for which indemnification is provided under this Section
8; then, and in each such case, the Company and such holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Restricted Stock offered by the registration statement
bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; PROVIDED, HOWEVER, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the public offering price of all
such Restricted Stock offered by it pursuant to such registration statement; and
(B) no person or entity guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled to contribution
from any person or entity who was not guilty of such fraudulent
misrepresentation.

    8.   CHANGES IN COMMON STOCK.  If, and as often as, there is any change in
the Common Stock by way of a stock split, stock dividend, combination or
reclassification, or through a merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof so that the rights and privileges granted hereby shall
continue with respect to the Common Stock as so changed. 

    9.   RULE 144 REPORTING.  With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, at all times
after 90 days after any registration statement covering a public offering of
securities of the Company under the Securities Act shall have become effective,
the Company agrees to: 

         (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act; 

         (b)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and 

         (c)  furnish to each holder of Restricted Stock forthwith upon request
a written statement by the Company as to its compliance with the reporting
requirements of such Rule 144 and of the Securities Act and the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed by the Company as such holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any Restricted Stock without
registration. 

    10.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to you as follows: 

         (a)  The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all requisite corporate action and will not

breach of or constitute (with due notice or lapse of time or both) a default
under any such indenture, agreement or other instrument or result in the
creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon any of the properties or assets of the Company. 

         (b)  This Agreement has been duly executed and delivered by the
Company and constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms.

    11.  TERMINATION.  This Agreement shall terminate on the earlier to occur

    12.  MISCELLANEOUS. 

         (a)  All covenants and agreements contained in this Agreement by or on
behalf of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto (including without
limitation transferees of any Warrants or Restricted Stock), whether so
expressed or not, PROVIDED, HOWEVER, that registration rights conferred herein
on the holders of Warrants or Restricted Stock shall only inure to the benefit
of a transferee of Warrants or Restricted Stock if (i) there is transferred to
such transferee at least 20% of the total shares of Restricted Stock originally
issued pursuant to the member Warrants to the direct or indirect transferor of
such transferee or (ii) such transferee is a partner, shareholder or affiliate
of a party hereto. 

         (b)  All notices, requests, consents and other communications
hereunder shall be in writing and shall be delivered in person, mailed by

Stock) or to the holders of Warrants or Restricted Stock (in the case of the
Company) in accordance with the provisions of this paragraph. 

         (c)  This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware.

of at least two-thirds of the outstanding shares of Restricted Stock. 

         (e)  This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one and the same instrument. 

         (f)  If any provision of this Agreement shall be held to be illegal,
invalid or unenforceable, such illegality, invalidity or unenforceability shall
attach only to such provision and shall not in any manner affect or render
illegal, invalid or unenforceable any other provision of this

Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

         (g)  each of the parties acknowledge that any breach of this Agreement
by any one of them will cause irreparable harm to the other parties thereto and
that in the event of such breach, the parties hereto shall be entitled, in
addition to monetary damages and to any other remedies available under this
Agreement and at law, to equitable relief, including injunctive relief.

Notes and Assumptions:

(1)  The Company issued common stock and common stock equivalents for 
     consideration below the initial public offering price of $6.00. 
     Consequently, in accordance with Staff Accounting Bulletin 83 (during 
     the periods covered by statements of operation included in the 
     registration statement) the followng methodology was used in determining 
     weighted average shares outstanding:

     Stock issued in a one year period immediately prior to the offering was 
treated as outstanding for the entire period and repurchase of shares using 
the treasury stock method at an offering price of $6.00.

(2)  Adjusted to reflect retroactively, a 18,333.486-for-1 stock split 
     approved by the Board of Directors of the Company on November 18, 1997.
