   This summary highlights information contained elsewhere in this prospectus.
This summary does not contain all of the information you should consider before
buying shares in the offering. Therefore, you should read the entire prospectus
carefully.

Orchid BioSciences

   We are engaged in the development and commercialization of technologies,
products and services designed to measure and use information related to
genetic diversity. We expect our proprietary technologies will significantly
enhance the way companies generate information about single nucleotide
polymorphisms, or "SNPs," the most common form of genetic diversity. The
pharmaceutical and medical communities can use genetic diversity information to
facilitate the development of highly specific and efficacious drugs, to improve
the effectiveness of existing drugs, and to increase the likelihood of success
of tissue transplants. Our proprietary technologies also have other commercial
applications outside of the healthcare field, including forensics and paternity
testing, as well as improved crop development and livestock breeding programs.

The Opportunity

   As the sequencing of the human genome nears a successful completion, we
believe the scientific community is entering a post-genomics era that will be
driven by the identification of genetic variation from person to person. We
expect that researchers will discover millions of SNPs over the next several
years, fueling a dramatic increase in the demand for studies associating
particular SNPs or combinations of SNPs with medically important attributes. We
expect that these studies will create a need for the analysis of billions of
SNPs. We call the performance of these analyses SNP scoring. Traditional
methods of conducting SNP scoring have significant limitations, including high
expense, low accuracy, lack of flexible design, lack of scalability and
sensitivity to variations in experimental conditions. The transition to the
post-genomics era and the increase in the number of SNP association studies
creates a pressing need for fast and flexible SNP scoring systems that can
score SNPs with a higher level of accuracy and at a lower cost than is
achievable with current methods.

Orchid's Unique Solution

   SNP-IT primer extension is a method of isolating the precise location of the
site of a suspected SNP by using a specially synthesized DNA primer and an
enzyme known as DNA polymerase which selectively extends the DNA chain by one
base at the suspected SNP location. Our SNP scoring system rapidly generates
highly accurate information relating to SNPs at a cost that is significantly
lower than conventional systems.

  We have designed our SNP-IT primer-extension technology to be automated and
usable in environments ranging from small scale laboratories to large scale
commercial facilities. It is also adaptable to a wide variety of instrument
platforms and laboratory conditions. We have also developed proprietary
technologies designed to control the flow of chemicals in miniaturized systems,
which we call our microfluidics technologies. We believe the combination of our
SNP-IT primer-extension technology with our proprietary microfluidics
technologies will enable us to gain competitive advantages in the cost and
capacity, or throughput, of SNP scoring conducted at our high-throughput
MegaSNPatron facility. As we refine our microfluidics technologies, we intend
to integrate them into our facility in order to increase its throughput to
millions of SNP scores per day and significantly reduce SNP scoring costs.

   Although we believe that our proprietary SNP-IT primer-extension SNP scoring
technology has advantages over alternative SNP scoring technologies, there are
elements of our technology which may be perceived as being limitations by our
potential customers.These include reliance upon third party prepared primers;
failure of potential customers to adopt our technologies; and reliance upon
third parties for sequence information.

   We believe our unique approach to SNP scoring will enable pharmaceutical
companies to improve their identification of lead drug candidates for
optimization and development by allowing them to generate and rapidly convert
genetic variation data into diverse collections of potentially useful targets
and drug candidates. In addition,

                                       4
<PAGE>

we believe pharmaceutical companies will use our technologies to assess the
effectiveness and toxicity of drug candidates which they are developing as well
as their currently-marketed drugs. We also intend to use our technologies to
develop proprietary applications of SNPs designed to improve medical treatment.
We believe our proprietary technologies will also be applicable to the
development of agricultural and diagnostic products. We believe these
applications of genetic diversity will be an important part of the post-
genomics era.

Our Target Markets

   We are targeting our SNP scoring technologies at a number of the most
rapidly developing markets in the field of genetic diversity. Specifically, we
believe our SNP scoring technologies can provide significant value in many
aspects of drug discovery, development and marketing as well as disease
predisposition assessment, diagnostic test development, transplantation
matching and development of agricultural products. Each of these markets
presents us with a wide range of opportunities for our technologies, including
SNP confirmation and SNP association studies, as well as the application of SNP
scoring to clinical trials and in clinical diagnostics.

Our Strategy

   Our objective is to become the premier provider of instruments, consumables,
services and technologies for SNP scoring and of other genetic diversity tests.
The key elements of our strategy to achieve this objective include the
following:

  . Rapid commercialization. We intend to rapidly commercialize our products
    and services, including our line of SNPstream instruments and SNPware
    kits for SNP scoring. We intend to commercialize SNPware kits for use on
    our hardware instrument platform, as well as on other SNP scoring
    platforms. For example, we are developing our SNPware consumable product
    line for Affymetrix, a leading DNA chip company. In addition, we intend
    to offer our products and services to other major companies for
    distribution to their customers. We currently provide SNP scoring
    services at our high-throughput MegaSNPatron facility.

  . Market extension. We intend to leverage our strong position in the
    research market to expand into the clinical and diagnostic markets. We
    believe these markets have the largest long-term growth potential in the
    genetic diversity field. We also intend to expand geographically by
    establishing international SNP scoring facilities to create additional
    service revenue and promote the sale of our entire line of products. We
    also intend to provide SNP scoring directly to consumers and physicians
    through one of our Web sites.

  . Proprietary SNP value creation. We intend to continue to create
    proprietary rights covering the association of SNPs with medically
    important attributes. We expect this will result in proprietary rights
    covering a broad range of new and existing drugs consisting of both
    "composition of matter patents," which cover the drugs themselves, and
    "use patents," which extend the drug's label coverage.

  . Sustained competitive advantage. We plan to build and sustain our
    competitive advantage in the genetic diversity field through scientific
    collaborations and acquisitions. We intend to use our microfluidics
    technologies to leverage our SNP scoring technologies and to maintain a
    competitive advantage in SNP scoring costs and capacity.

Our Products and Services

   We currently offer our SNPstream hardware system and SNPware consumable kits
to enable customers to conduct SNP scoring. We also offer SNP scoring services
at our high-throughput MegaSNPatron facility and genetic diversity testing
services through our clinical laboratories, or Regional GeneScreen Centers, for
use in forensic and paternity testing as well as to improve the success of bone
marrow transplants.

                                  RISK FACTORS

   You should carefully consider the following risk factors and all other
information contained in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk. If any of the
following risks actually occurs, we may not be able to conduct our business as
currently planned and our financial condition and operating results could be
seriously harmed. In that case, the market price of our common stock could
decline, and you could lose all or part of your investment. See "Special Note
Regarding Forward-Looking Statements."

                         Risks Related to Our Business

We are at an early stage of development and may never become profitable.

   We organized our company as a Delaware corporation on March 8, 1995 and have
a short operating history. The market for the products and services that we
develop, manufacture and market, all of which are derived from genomics and
microfluidics technologies, is uncertain. We face risks related to our ability
to:

  . develop, market and maintain competitive technologies, products and
    services;

  . anticipate and adapt to changes in our rapidly evolving markets;

  . retain current collaborators or customers and attract new collaborators
    and customers for our SNPware consumables, kits and SNPstream
    instruments;

  . implement and successfully execute our business strategy and sales and
    marketing initiatives in order to increase our brand recognition for our
    SNPware consumables, kits and SNPstream instruments;

  . attract, retain and motivate qualified management, technical and
    scientific personnel;

  . obtain substantial additional capital to support the expenses of
    developing our technologies and commercializing our SNPware consumables,
    kits and SNPstream instruments; and

  . transition successfully from a company with a research focus to a company
    capable of supporting commercial activities.

If we fail to adequately manage these risks, we may never become profitable and
our financial condition would suffer.

We had an accumulated deficit of $50.8 million as of December 31, 1999 and
expect to continue to incur substantial operating losses for several years.

   We have had substantial operating losses since our inception, and we expect
our operating losses to continue over the next several years. For example, we
experienced net losses of $28.2 million in 1999, $11.5 million in 1998 and $9.9
million in 1997. As of December 31, 1999, we had an accumulated deficit of
$50.8 million. In order to further develop our single nucleotide polymorphism,
or SNP, scoring and microfluidics technologies, we will need to incur
significant expenses in connection with our internal research and development
and commercialization programs. As a result, we expect to incur operating
losses for several years.

Fluctuations in our quarterly revenue and operating results may negatively
impact our stock price.

   Our revenue and results of operations have fluctuated significantly in the
past and we expect significant fluctuations to continue in the future due to a
variety of factors, many of which are outside of our control. These factors
include:

  . the volume and timing of orders for our SNPware consumables, kits,
    SNPstream instruments and our other products and services;

  . changes in the mix of our products and services offered;

                                       8
<PAGE>

  . the number, timing and significance of new products and services
    introduced by our competitors;

  . our ability to develop, market and introduce new and enhanced products
    and services on a timely basis;

  . changes in the cost, quality and availability of reagents and components
    required to manufacture or use our products; and

  . availability of commercial and government funding to researchers who use
    our products and services.

   Research and development costs associated with our technologies, products
and services, as well as personnel costs, marketing programs and overhead
account for a substantial portion of our operating expense. We cannot adjust
these expenses quickly in the short term. If our revenue declines or does not
grow as anticipated, we may not be able to reduce our operating expenses
accordingly. Failure to achieve anticipated levels of revenue could therefore
significantly harm our operating results for a particular fiscal period. In
addition, if our operating results in some quarters fail to meet the
expectations of public market analysts or investors, the market price of our
common stock is likely to fall.

We have limited manufacturing experience and will need to acquire new
facilities to manufacture our products on a commercial scale.

   We have limited manufacturing experience and currently possess only a single
facility capable of manufacturing limited quantities of our SNPware products
for sale to our customers and for internal use. To achieve the production
levels necessary for successful commercialization, we will need to scale-up our
manufacturing facilities and establish automated manufacturing capabilities. We
are presently searching for a facility to meet our manufacturing needs beyond
2000. If we are unable to acquire additional manufacturing facilities or
successfully scale-up our existing manufacturing capability, we may not be able
to provide our customers with the quantity of products and services they
require, which would result in reduced revenue. If any natural disaster were to
significantly damage our manufacturing facility or if other events were to
cause our operations to fail, these events could prevent us from developing and
manufacturing our products. Furthermore, we may not have adequate insurance to
cover the damage, which would adversely affect our results of operations.

We have limited sales and marketing experience, and as a result, may be unable
to compete successfully with our competitors in commercializing our potential
products and services.

   We have limited experience in sales and marketing. We do not have a direct
sales force and rely principally upon a small number of employees who do not
have specific training in sales. We intend to market our SNP scoring and
microfluidics technologies and applications through collaborations and
distribution agreements with pharmaceutical and biotechnology companies. We
cannot assure you that we will be able to establish a successful direct sales
force or to establish collaboration or distribution arrangements to market our
products and services, which could have a material adverse effect on our
financial condition and business strategy.

Our technologies and initial commercial products may not be commercially viable
or successful, which would adversely affect our revenue.

   We have not yet completed the development of our SNP scoring technologies or
our high-throughput MegaSNPatron facility for SNP scoring, both of which are
important elements of our business strategy. We may not be able to successfully
develop these technologies or this facility. Even if we develop these
technologies, we cannot be certain that our prospective customers will value
them. We are currently developing and commercializing only a limited number of
products based on our SNP scoring technologies. We cannot assure you that we or
our customers will be able to use these technologies to successfully identify
and score SNPs. In addition, any SNPs, which we or our customers score may not
be useful in assisting pharmaceutical or diagnostic product development. Our
SNP scoring technologies are in part directed toward the role of genes

                                       9
<PAGE>

and polymorphisms in complex diseases. A limited number of companies have
developed or commercialized products based on gene discoveries and/or
polymorphisms to date. Accordingly, even if we or our customers are successful
in scoring SNPs and associating these SNPs with specific drug responses or
diseases, we cannot assure you that these discoveries will lead to the
development of therapeutic or diagnostic products. If we fail to successfully
develop our SNP scoring technologies or any commercially successful therapeutic
or diagnostic products based on such technologies, we may not achieve a
competitive position in the market.

   Our SNP scoring technologies involve novel uses of instrumentation, software
and technologies that require validation in commercial applications. Previously
unrecognized defects or limitations of our SNP scoring technologies may become
apparent in these commercial applications. As a result, we may be unable to
validate or achieve the improvements in the components of our SNP scoring
technologies necessary for their successful commercialization.

   Our SNP scoring technologies will also need to compete against well-
established techniques and enhancements for discovering novel drugs, including
combinatorial chemistry and high-throughput screening. We may be unable to
compete successfully against existing techniques and instruments, which would
materially and adversely affect our ability to market and sell our products and
services and our revenue.

If our customers do not purchase significant volumes of SNPware consumables,
our rapid commercialization strategy could fail.

   Our customers may not generate sufficient data in a cost effective manner
using our SNPstream product line. This may limit their purchases of our SNPware
consumables, kits and other consumables necessary to conduct SNP scoring with
our SNPstream systems. Other factors which may limit the use of our kits and
consumables include the acceptance of our technologies by our customers and the
training of our customers' personnel. If our customers are slow to, or never,
achieve sufficient results using our SNPstream system, or fail to purchase
sufficient quantities of our SNPware consumables and kits, we may never achieve
profitability. Further, our customers may not adopt SNPware consumables and
kits for use with their own instrument systems. Even if they do, our products
may not work on their systems. Either circumstance would materially and
adversely affect our revenue and our rapid commercialization strategy.

If we fail to maintain the paternity testing service contracts we have with
various state agencies or fail to enter into additional contracts, we would
lose a significant source of revenue.

   We currently derive a substantial portion of our revenue from the DNA
testing services we provide in the paternity and forensic fields. These
services are heavily dependent upon contracts we have with various state
agencies, which are typically open to bid and awarded every one to three years.
The process and criteria for these awards are typically complex and highly
competitive. We may not be able to maintain any of our existing state contracts
or be the successful bidder on any additional state contracts which may become
available in the future on terms acceptable to us, which would adversely affect
our results of operations and financial condition.

We will require additional funding to fund our future operating plans which may
not be available on acceptable terms, if at all.

   We anticipate that our existing capital resources may not be sufficient to
fund our future operating plans and we may therefore need to raise significant
additional capital. We expect our capital and operating expenses to be
significant over the next several years. We have expended significant resources
in developing our MegaSNPatron facility and expect to continue to expend
significant resources to develop this facility, increase our research and
development and commercialization activities and acquire an additional
manufacturing facility. The amount of additional capital which we will need to
raise will depend on many factors, including:

  . our progress with research and development;

  . the number and breadth of our research programs;

                                       10
<PAGE>

  . our internal use of and our level of success in selling our SNP scoring
    products and associated technologies;

  . our ability to establish and maintain successful collaborations; and

  . the costs incurred by us in enforcing and defending our patent claims and
    other intellectual property rights.

   We believe the proceeds from this offering, together with cash on hand, will
be sufficient to fund our operating costs for at least the next 18 months.
However, we may need additional financing sooner if we:

  . decide to expand faster than planned;

  . develop new or enhanced services or products ahead of schedule;

  . need to respond to competitive pressures; or

  . decide to acquire complementary products, businesses or technologies.

   If we raise additional funds through the sale of equity or convertible debt
or equity-linked securities, your percentage ownership in the company will be
reduced. In addition, these transactions may dilute the value of our
outstanding stock. We may issue securities that have rights, preferences and
privileges senior to our common stock. If we raise additional funds through
collaborations or licensing arrangements, we may relinquish rights to certain
of our technologies or products, or grant licenses to third parties on terms
that are unfavorable to us. We may be unable to raise additional funds on terms
acceptable to us. If future financing is not available to us or is not
available on terms acceptable to us, we may not be able to fund our future
needs which would have a material adverse effect on our results of operations
and financial condition.

If we cannot enter into new collaborations or licensing agreements, we may be
unable to develop or commercialize our technologies, products and services.

   Our strategy for developing and commercializing products based on our
discoveries depends upon our ability to form research collaborations and
licensing arrangements. As a result, we may be dependent on our collaborators
and licensees for marketing of SNP scoring systems, regulatory approval and
manufacturing and marketing of therapeutic and diagnostic products resulting
from the application of our technologies. We may not be able to enter into such
research collaborations and licensing arrangements or implement our strategy to
develop and commercialize therapeutic and diagnostic products based upon our
discoveries which would have a material adverse effect on our results of
operation and financial condition.

   The early termination of any of our collaborations or licenses, including
our collaboration with Affymetrix, could harm our business and financial
condition.

   Our collaboration agreement with Affymetrix may be terminated early under
certain circumstances, including in the event of a breach of a material term by
us. In addition, we intend to seek additional collaborations and licenses with
third parties, who may negotiate provisions with us that allow them to
terminate their agreements with us prior to the expiration of the negotiated
term under certain circumstances. If Affymetrix or any other third party
collaborator or licensee were to terminate its agreement with us or otherwise
fail to perform its obligations under our collaboration or to complete them in
a timely manner, we could lose significant revenue.

   We may not be able to attract and retain consultants and scientific
advisors.

   We have historically maintained relationships with consultants and
scientific advisors at academic and other institutions who have conducted
research on our behalf critical to the development of our technologies. The
majority of these individuals have commitments to other entities and have
limited time available for us. Some of these entities may also compete with us.
We will need to establish new relationships with consultants

                                       11
<PAGE>

and scientific advisors in our genetic diversity fields. We will have little,
if any, control over the activities of any new collaborators and can expect
only limited amounts of their time to be dedicated to our activities. Our
ability to discover and score SNPs and commercialize products based on those
discoveries may depend in part on continued collaborations with researchers at
academic and other institutions. We cannot be certain that any of our existing
collaborations will be successful. Further, we may not be able to negotiate
acceptable collaborations in the future with additional consultants or
scientific advisors at academic and other institutions.

If we do not successfully distinguish and commercialize our products and
services, we may be unable to compete successfully with our competitors or to
generate significant revenue.

   We are subject to significant competition from organizations that are
pursuing products and services that are substantially similar to our proposed
products and services. Many of the organizations competing with us have greater
experience in financial, manufacturing, marketing, sales distribution and
technical regulatory matters than we do. In the SNP scoring field, we compete
with several companies offering alternative technologies based on indirect
detection of hybridization and/or labeling which differ in the various methods
of amplifying and separating samples or of detecting and analyzing SNPs. We may
also compete against our customers, which could adversely affect our
relationships with them.

   We believe our future success will depend, in large part, on our ability to
maintain a competitive position in the instrument and kit-based SNP scoring,
pharmacogenetics and microfluidics product fields and in the SNP scoring
services field. We or others may make rapid technological developments which
may result in our technologies, products or services becoming obsolete, before
we recover the expenses incurred to develop them. Our inability to make the
enhancements to our technologies necessary to compete successfully with newly
emerging technologies would have a material adverse effect on our competitive
position.

If we are unable to protect our proprietary methods and technologies, we may
not be able to commercialize products and services.

   If our patent applications do not result in issued patents, our competitors
may obtain rights to commercialize our discoveries which would harm our
competitive position.

   Our commercial success will depend, in large part, on our ability to obtain
patent protection on many aspects of our business, including the discovery and
the association of particular SNPs with disease predisposition and adverse drug
metabolism, and on the products, methods and services we develop. We may not be
able to obtain new patents for our SNPware consumables, kits and SNPstream
systems. We intend to apply for patent protection on novel SNPs of known genes
and their uses, as well as novel uses for previously identified SNPs discovered
by third parties. In the latter cases, we would need a license from the holder
of the patent with respect to such SNP in order to make, use or sell any
related products. We may not be able to acquire such licenses on terms
acceptable to us, if at all.

   If any genomic sequence information related to a SNP is publicly released
prior to the time we apply for patent protection on a related SNP, we may be
unable to obtain patent protection with respect to that SNP. In addition,
certain parties are attempting to rapidly identify and characterize genes and
SNPs through the use of gene expression analysis and other technologies. To the
extent any patents issue to other parties on such partial or full-length genes
or SNPs or uses for such genes or SNPs, the risk increases that the sale of
products, including therapeutics, or processes developed by us or our
collaborators may give rise to claims of patent infringement against us. Others
may have filed and, in the future, are likely to file patent applications
covering SNPs. Any such patent application could have priority over our patent
applications and could further require us to obtain rights to previously issued
patents covering SNPs. We cannot assure you that any license that we may
require under any such patent will be made available to us on commercially
acceptable terms, if at all.

                                       12
<PAGE>

   The scope of our issued patents may not provide us with adequate protection
of our intellectual property, which would harm our competitive position.

   Any issued patents that cover our proprietary technologies may not provide
us with substantial protection or be commercially beneficial to us. The
issuance of a patent is not conclusive as to its validity or its
enforceability. The United States Patent and Trademark Office may invalidate
our patents. In addition, third parties may have patents of their own which
could, if asserted, prevent us from practicing our patented technologies
including the methods we use to conduct SNP scoring. If we are otherwise unable
to practice our patented technologies, we may not be able to commercialize our
technologies, products or services and our competitors could commercialize our
technologies.

   If significant data on identified SNPs becomes unavailable or available only
on unacceptable terms, we could experience increased research and development
expenses.

   We currently obtain and rely on our continued access to significant data on
SNPs from several sources, including The SNP Consortium, Ltd., a group of
leading pharmaceutical companies identifying SNPs. Although many of these
sources make information relating to identified non-proprietary SNPs publicly
and freely available, we cannot be sure that we will continue to obtain this
SNP data without paying licensing or other fees to third parties. If SNP data
is no longer publicly or freely available or is available only at significant
costs, we may be unable to implement our business strategy.

   We may need to initiate lawsuits to protect or enforce our patents and other
intellectual property rights, which could result in the forfeiture of these
rights.

   In order to protect or enforce our patent rights, we may need to initiate
patent litigation against third parties. These lawsuits could be expensive,
take significant time, and could divert management's attention from other
business concerns. These lawsuits could result in the invalidation or a
limitation in the scope of our patents or forfeiture of the rights associated
with our patents. We cannot assure you that we will prevail or that a court
will not find damages or award other remedies in favor of our opposing party in
any of these suits. During the course of these suits, there may be public
announcements of the results of hearings, motions and other interim proceedings
or developments in the litigation. Securities analysts or investors may
perceive these announcements to be negative, which could cause the market price
of our stock to decline.

   Our success will depend partly on our ability to operate without infringing
on or misappropriating the intellectual property rights of others.

   We may be sued for infringing on the intellectual property rights of others.
Intellectual property litigation is costly, and could affect our results of
operations. If we do not prevail in any intellectual property litigation, in
addition to any damages we might have to pay, we could be required to stop the
infringing activity, or obtain a license to or design around the intellectual
property in question. If we are unable to obtain a required license on
acceptable terms, or are unable to design around any third party patent, we may
be unable to sell some of our products and services, which would result in
reduced revenue.

   Other rights and measures that we rely upon to protect our intellectual
property may not be adequate to protect our products and services and could
reduce our ability to compete in the market.

   In addition to patents, we rely on a combination of trade secrets, copyright
and trademark laws, nondisclosure agreements and other contractual provisions
and technical measures to protect our intellectual property rights. While we
require employees, collaborators, consultants and other third parties to enter
into confidentiality and/or non-disclosure agreements where appropriate, any of
the following could still occur:

  . the agreements may be breached;

  . we may have inadequate remedies for any breach;

  . proprietary information could be disclosed to our competitors; or

  . others may independently develop substantially equivalent proprietary
    information and techniques or otherwise gain access to our trade secrets
    or disclose such technologies.

                                       13
<PAGE>


   If for any of the above reasons our intellectual property is disclosed or
misappropriated, it would harm our ability to protect our rights and our
competitive position.

Future acquisitions or investments could disrupt our ongoing operations,
increase our expenses and adversely affect our revenue.

   We have recently completed acquisitions of Molecular Tool and GeneScreen.
Although we have no commitments or agreements with respect to any additional
acquisitions at present, we anticipate that a portion of our future growth may
be accomplished by acquiring existing businesses. Factors that will affect the
success of any acquisition we might make include our ability to integrate
acquired personnel, operations, products and technologies into our organization
effectively, to motivate key personnel and to retain customers of acquired
businesses. We may not be able to identify suitable acquisition opportunities,
obtain any necessary financing for such acquisitions on acceptable terms or
successfully integrate acquired personnel and operations. In addition, as a
public company, the cost of acquiring companies may increase relative to the
cost of acquiring similar companies when we were a private company. These
difficulties could disrupt our ongoing business, distract our management and
employees, increase our expenses and materially and adversely affect our
revenue.

Our failure to comply with any applicable government regulation may affect our
ability to develop, produce, or market our potential products and may adversely
affect our results of operation.

   Our research and development, manufacturing and service activities involve
the controlled use of hazardous materials and chemicals and patient samples. We
are subject to federal, state and local laws and regulations governing the use,
storage, handling and disposal of such materials and certain waste products, as
well as the conveyance, processing, and storage of and data on patient samples.
Further, we are subject to the Clinical Laboratory Improvement Act, or CLIA, as
a result of our recent acquisition of three GeneScreen laboratories. CLIA
imposes certain certification requirements on all clinical laboratories
performing tests on human specimens for the purpose of providing information
for the diagnosis, prevention or testing of any diseases. Although we believe
we comply in all material respects with the standards prescribed by federal,
state and local laws and regulations, if we fail to comply with applicable laws
or regulations, including CLIA, or if an accident occurs, we could be required
to pay significant penalties or be held liable for any damages that result and
this liability could exceed our financial resources.

If we fail to comply with federal and state industry regulations, we may not be
able to provide certain services at our laboratories.

   All three of our GeneScreen laboratories must comply with various industry
regulations and accreditation standards in order to continue to provide our
paternity testing, forensic testing and bone marrow typing services. For
example, our GeneScreen laboratories have obtained accreditation from the
American Association of Blood Bank in order to provide paternity testing, from
the National Forensic Science Testing Center in order to provide criminal
forensic testing services and from the American Society of Histocompatibility
and Immunology in order to provide bone marrow donor typing services. We cannot
assure you that we will be able to maintain our accreditations with any of
these authorities. If we fail to comply with the applicable regulations
promulgated by any of these agencies or if we were to lose our accreditation by
any of them, the relevant authority could require us to close our laboratories,
which could eliminate or significantly reduce the revenue supporting our
GeneScreen business results of operation.

The sale of our SNPware consumables, SNPkits, and SNPstream instruments
involves a lengthy and expensive sales cycle that may not result in sales.

   Our ability to obtain customers for our SNPware consumables, SNPkits, and
SNPstream instruments will depend in significant part upon the perception that
our products and services can help accelerate or improve drug discovery and
development efforts or have beneficial effects on human health. Our average
sales cycle is lengthy due to the education effort that is required to
effectively sell the benefits of our products and services to

                                       14
<PAGE>

a variety of constituencies within potential customers, including research and
development personnel and key management. As a result, in many instances we may
expend significant human and capital resources to market our products, without
any resulting sales.

If our customers fail to accurately prepare DNA samples for use with our
SNPware and SNPstream product line or for analysis at our MegaSNPatron
facility, our products and services may fail to produce accurate results.

   Before using our SNPstream product line and MegaSNPatron SNP scoring service
facility, customers must prepare samples by following several steps that are
prone to human error, including DNA isolation and DNA segment amplification. If
they do not prepare DNA samples appropriately, our SNPstream products and
MegaSNPatron SNP scoring service will not generate an accurate reading.
Alternatively, they may achieve lower levels of throughput than the levels for
which our system was designed. If our customers generate inaccurate readings or
are unable to achieve expected levels of throughput, they may not continue to
purchase our consumables, instruments or services, which could materially and
adversely affect our revenue.

We may be held liable for any inaccuracies associated with our research and DNA
testing services, which may require us to defend ourselves in costly
litigation.

   Our Regional GeneScreen Centers provide pharmacogenetic, forensic, and
paternity testing services. Claims may be brought against us for false
identification of paternity or other inaccuracies. Litigation of these claims
can be costly. We could expend significant funds during any litigation
proceeding brought against us. Further, if a court were to require us to pay
damages to a plaintiff, the amount of such damages could significantly harm our
financial condition.

If our vendors fail to supply us with components for which availability is
limited, we may experience delays in our product development and
commercialization.

   Certain key components of our SNP scoring and microfluidic chip system
technologies are currently available only from a single source or a limited
number of sources. We currently rely on outside vendors to manufacture certain
components of our SNPstream system and certain reagents we provide in our
SNPware kits. Some or all of these key components may not continue to be
available in commercial quantities at acceptable costs. For example, we have an
agreement with Beckman Coulter under which they supply us with the components
of our SNPstream system and with NEN Life Science Products, Inc. under which
they supply us with some of the key reagents contained in our SNPware kits. We
rely on third parties to provide DNA samples to us and to perform DNA
synthesis. It could be time consuming and expensive for us to seek alternative
sources of supply. Consequently, if any events cause delays or interruptions in
the supply of our components, we may not be able to supply our customers with
our products and services on a timely basis which would adversely affect our
results of operations.

If we fail to retain our key personnel and hire, train and retain qualified
employees, we may not be able to compete effectively, which could result in
reduced revenue.

   Our future success will depend on the continued services and on the
performance of our senior management, in particular the services of:

  . Dale R. Pfost, Ph.D., our Chairman of the Board, President and Chief
    Executive Officer; and

  . Donald R. Marvin, our Senior Vice President, Chief Operating Officer,
    Chief Financial Officer and Secretary.

   If either of Dr. Pfost or Mr. Marvin were to be hired away from us by a
competitor, or if for any reason they could not continue to work for us, we
would have difficulty hiring officers with equivalent skills in general and
financial management. We do not currently carry "key man" life insurance, so
the loss of the services of either of these individuals could seriously impair
our ability to operate or to compete in our industry.

                                       15
<PAGE>

   In addition, our researchers, scientists and technicians have significant
experience in research and development related to genetic diversity. If we were
to lose these employees to our competitors, we could spend a significant amount
of time and resources to replace them, which could impair our research and
development efforts. Further, in order to scale-up our manufacturing capability
and to further our research and development efforts, we will need to hire,
train, and retain additional research, scientific, and technical personnel. If
we are unable to do so, we may experience delays in the research, development
and commercialization of our technologies, products and services.


                  Risks Related to the Biotechnology Industry

Public opinion regarding ethical issues surrounding the use of genetic
information may adversely affect demand for our products.

   Public opinion regarding ethical issues related to the confidentiality and
appropriate use of genetic testing results may influence governmental
authorities to call for limits on, or regulation of the use of, genetic
testing. In addition, such authorities could prohibit testing for genetic
predisposition to certain conditions, particularly for those that have no known
cure. Any of these scenarios could reduce the potential markets for our
products, which could materially and adversely affect our revenue.

Commercializing pharmaceutical products has associated risks, including
compliance with pre-clinical and clinical testing and manufacturing
regulations.

   Although it is likely to be years before we develop any potential
pharmaceutical products, any future products will require significant research,
development and pre-clinical and clinical testing before we submit any
regulatory application for their commercial use. If we were to undertake any of
these activities without the collaboration of others, we would have to expend
significant funds. Any of our potential pharmaceutical products will be subject
to the risks of failure inherent in the development of pharmaceutical products
based on new technologies. These risks include the following possibilities:

  . that such potential pharmaceutical products will be found to be unsafe or
    non-efficacious or otherwise fail to receive necessary regulatory
    clearances;

  . that the products, if safe and efficacious, will be difficult to
    manufacture on a large scale or uneconomical to market;

  . that proprietary rights of third parties will preclude us or our
    collaborative partners from marketing such products; or

  . that third parties will market superior or equivalent products.

If we have difficulty managing these risks, we may not be able to develop any
commercially viable products.

   In addition, clinical trials or marketing of any such potential
pharmaceutical products may expose us to liability claims from the use of such
pharmaceutical products. We may not be able to obtain product liability
insurance or, even if we do, any coverage we obtain could be insufficient or
costly. In addition, should we choose to manufacture or to develop
pharmaceutical products ourselves, we will have to make significant investments
in pharmaceutical product development, marketing, sales and regulatory
compliance resources, and we will have to establish or contract for the
manufacture of products under the regulations of the FDA regarding good
manufacturing practices. We cannot assure you that we will be able to develop
or commercialize successfully any potential pharmaceutical products.

                      Risks Associated With This Offering

Future issuance of our preferred stock may dilute the rights of our common
stockholders.

   Our Board of Directors has the authority to issue up to 5,000,000 shares of
preferred stock and to determine the price, privileges and other terms of
these shares. The Board of Directors may exercise this authority without any
further approval of our stockholders. The rights of the holders of common
stock may be adversely affected by the rights of our holders of our preferred
stock that may be issued in the future.

We have various mechanisms in place that you as a stockholder may not consider
favorable, which may discourage takeover attempts.

   Following this offering, certain provisions of our certificate of
incorporation and bylaws, as well as Section 203 of the Delaware General
Corporation Law, may discourage, delay or prevent a change in control of our
company, even if the change of control would be beneficial to stockholders.
These provisions include:

  . authorizing the issuance of "blank check" preferred stock that could be
    issued by our Board of Directors to increase the number of outstanding
    shares and thwart a takeover attempt;

  . a classified Board of Directors with staggered, three-year terms, which
    may lengthen the time required to gain control of our Board of Directors;

  . prohibiting cumulative voting in the election of directors, which will
    allow a majority of stockholders to control the election of all
    directors;

  . requiring super-majority voting to effect certain amendments to our
    certificate of incorporation and bylaws;

  . limitations on who may call special meetings of stockholders;

  . prohibiting stockholder action by written consent, which requires all
    actions to be taken at a meeting of stockholders; and

  . establishing advance notice requirements for nominations of candidates
    for election to the Board of Directors or for proposing matters that can
    be acted upon by stockholders at stockholder meetings.

   In addition, our stock incentive plan may discourage, delay or prevent a
change in control of our company.

You could lose all or part of your investment if the market price of our
common stock falls below the initial public offering price.

   The initial public offering price will be determined through negotiations
between us and the representatives of the underwriters based on factors that
may not be indicative of future market performance. The initial public
offering price may bear no relationship to the price at which the common stock
will trade upon completion of this offering. An active public market for our
common stock may not develop or be sustained after this offering, and the
market price could fall below the initial public offering price. As a result,
you could lose all or part of your investment.

   In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of its
securities. We may in the future be the target of similar litigation.
Securities litigation could result in substantial costs and divert
management's attention and resources, which could have a material adverse
effect on our business and the market for our common stock.

Our directors, executive officers and principal stockholders will have
substantial control over our affairs.

   Our directors, executive officers and principal stockholders will
beneficially own, in the aggregate, approximately 37% of our common stock
following this offering. These stockholders, acting together, will

                                      17
<PAGE>

have the ability to exert substantial influence over all matters requiring
approval by our stockholders. These matters include the election and removal of
directors and any merger, consolidation or sale of all or substantially all of
our assets. In addition, they may dictate the management of our business and
affairs. This concentration of ownership could have the effect of delaying,
deferring or preventing a change in control, or impeding a merger or
consolidation, takeover or other business combination of which you might
otherwise approve.

We will have broad discretion as to the use of proceeds of this offering and
may fail to use them effectively.

   We have no exact plan with respect to the use of the net proceeds of this
offering and have not committed these proceeds to any particular purpose apart
from expenses of the business and general working capital. Accordingly, our
management will have broad discretion in applying the net proceeds of this
offering and may use the proceeds in ways with which you and our other
stockholders may disagree. We may not be able to invest these funds effectively
which would adversely affect our financial condition.

You will suffer substantial dilution in the net tangible book value of the
common stock you purchase in this offering.

   The initial public offering price of our common stock will be substantially
higher than the pro forma net tangible book value per share of our common
stock. Based on an assumed initial public offering price of $12.00 per share,
if you purchase shares of common stock in this offering, you will suffer
immediate and substantial dilution of $7.53 per share in the pro forma net
tangible book value of the common stock at December 31, 1999 after giving
effect to the sale of Series E mandatorily redeemable convertible preferred
stock in January 2000. To the extent outstanding options and warrants are
exercised, you will suffer further dilution.

There is a large number of shares that may be sold in the market following this
offering, which may depress the market price of our common stock.

   After this offering, based on the number of shares outstanding on March 31,
2000, we will have approximately 33,989,381 shares of common stock outstanding.
All of the shares being offered in this offering will generally be freely
tradable.

   Sales of a substantial number of these shares of our common stock in the
public market following this offering could cause the market price of our
common stock to decline. The number of shares of common stock available for
sale in the public market is limited by restrictions under federal securities
law and under lock-up agreements that our stockholders have entered into with
the underwriters and with us. Those lock-up agreements restrict our
stockholders from selling, pledging or otherwise disposing of their share for a
period of 180 days after the date of this prospectus without the prior written
consent of Credit Suisse First Boston Corporation. However, Credit Suisse First
Boston Corporation may, in its sole discretion, release all or any portion of
the common stock from the restrictions of the lock-up agreements. The following
table indicates approximately when the 25,989,381 shares of our common stock
that are not being sold in the offering but which were outstanding as of March
31, 2000 will be eligible for sale into the public market:

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   This prospectus contains forward-looking statements that involve risks and
uncertainties. Discussions containing forward-looking statements may be found
in the material set forth under "Management's Discussion and Analysis of
Financial Condition and Results of Operations and Business," as well as in this
prospectus generally. We generally use words such as "believe," "intend,"

                                USE OF PROCEEDS

   We estimate that our net proceeds from the sale of 8,000,000 shares of
common stock we are offering, at an assumed initial public offering price of
$12.00 per share, will be $87.8 million after deducting underwriting discounts
and commissions and the estimated offering expenses payable by us. We expect to
use the net proceeds for general corporate purposes, including potential
acquisitions and to construct or acquire additional manufacturing capacity.

   The amount and timing of our actual expenditures will depend upon numerous
factors, including the status of our product development and commercialization
efforts, the amount of proceeds actually raised in this offering, the amount of
cash generated by our operations, competition, and sales and marketing
activities. We may also use a portion of the proceeds for the acquisition of,
or investment in, companies, technologies or assets that we believe can
complement our business. However, we have no present understandings,
commitments or agreements to enter into any potential acquisitions or make any
investments. Further, we have not determined the amounts we plan to spend on
any of the areas listed above or the timing of these expenditures. As a result,
our management will have broad discretion to use the net proceeds from this
offering. Pending application of the net proceeds as described above, we intend
to invest the net proceeds of the offering in short-term, investment-grade,
interest-bearing securities.

   The principal purposes of this offering are:

  . to increase our equity capital;

  . to facilitate future access by us to public equity markets;

  . to increase visibility and credibility in a marketplace where several of
    our current and prospective competitors are, or may in the future be,
    public companies; and

  . to enhance our ability to use our common stock as consideration for
    acquisitions and as a means of attracting and retaining key employees.

                                DIVIDEND POLICY

   We have never paid cash dividends on our common stock. We currently
anticipate retaining all of our future earnings, if any, to support operations
and to finance the growth and development of our business and do not anticipate
paying any cash dividends for the foreseeable future. The terms of future
credit agreements may prevent us from paying any dividend or making any
distributions or payment with respect to our capital stock.

     mandatorily redeemable convertible preferred stock sold in January 2000
     for net proceeds of $29,573,564 and the issuance in January 2000 of
     Series E manditorily redeemable convertible preferred stock recorded as
     "Series E to be issued" at December 31, 1999, upon the closing of this
     offering; and

  .  our pro forma as adjusted capitalization reflecting the aforementioned

                                    DILUTION

   The pro forma net tangible book value of our common stock as of December 31,
1999, after reflecting the conversion of all shares of convertible preferred
stock and mandatorily redeemable convertible preferred stock outstanding and
recorded as to be issued at December 31, 1999 into shares of common stock upon
the closing of this offering, was $33.1 million, or $1.68 per share. Pro forma
net tangible book value per share represents the amount of our total tangible
assets less total liabilities divided by the number of shares of common stock
outstanding, assuming conversion, as of December 31, 1999, of all then
outstanding shares (and those shares recorded in our Consolidated Financial
Statements as "Series E to be issued") of mandatorily redeemable convertible
preferred stock and convertible preferred stock into shares of common stock. We
have adjusted this pro forma net tangible book value to show the increase
attributable to the shares of Series E mandatorily redeemable convertible
preferred stock sold in January 2000. Dilution in pro forma net tangible book
value per share represents the difference between the amount per share paid by
purchasers of shares of common stock in this offering and the pro forma net
tangible book value per share of our common stock immediately afterwards.
Assuming the sale of 8,000,000 shares of common stock offered by this
prospectus at an assumed initial public offering price of $12.00 per share, and
after deducting underwriting discounts and commissions and the estimated
offering expenses payable by us, our net tangible book value as of December 31,
1999, after giving effect to the sale of Series E mandatorily redeemable
convertible preferred stock in January 2000, would have been approximately
$150.4 million, or $4.47 per share. This represents an immediate increase in
net tangible book value to existing investors of $2.03 per share and decrease
in net tangible book value of $7.53 per share to new investors purchasing
shares of common stock in this offering. The following table illustrates this
dilution on a per share basis:

stockholders and number of shares used in the computation of per share amounts.

   The following transactions had a material effect on the comparability of the
data presented in the consolidated financial data above, as follows: contract
revenue received from related parties relating to the SmithKline Beecham
agreement, the acquisition of certain Molecular Tool assets in September 1998,
the acquisition of GeneScreen in December 1999, the sale of Series C
mandatorily redeemable convertible preferred stock in December 1997 and March
1998 and the sale of Series E mandatorily redeemable convertible preferred
stock in December 1999. Please see our notes to the consolidated financial
statements for further discussions of these transactions.

                UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

   The following unaudited pro forma consolidated statement of operations is
based on our historical consolidated financial statements for the year ended
December 31, 1999 and the historical financial statements of GeneScreen for the
period from January 1, 1999 to December 29, 1999, included elsewhere in this
prospectus, adjusted to give pro forma effect to the acquisition of GeneScreen
on December 30, 1999 as if it occurred on January 1, 1999. Our historical
consolidated balance sheet as of December 31, 1999 reflects our acquisition of
GeneScreen.

   On December 30, 1999, we acquired all of the outstanding shares of common
and preferred stock of GeneScreen in exchange for a price of $42.7 million
which was satisfied by consideration consisting primarily of up to 4,000,000
shares of our Series E mandatorily redeemable convertible preferred stock with
a stated value of $4.50 per share. The note payable to GeneScreen related to
our purchase of the Molecular Tool assets in the amount of $3,547,821 and other
liabilities totaling $421,000 were also cancelled. We accounted for our
acquisition of the GeneScreen under the purchase method of accounting. We have
included $28,530,000 as a beneficial conversion feature in the purchase price
which was recorded as an increase to additional paid-in capital. The amount of
the beneficial conversion feature was calculated as the difference between the
$11.75 per share fair value of our common stock on December 22, 1999, the
commitment date, over the $4.50 per share conversion price of the stock.

   The unaudited pro forma consolidated statement of operations for the year
ended December 31, 1999 gives effect to the GeneScreen acquisition as if it had
occurred on January 1, 1999. The unaudited pro forma adjustments are based upon
available information and certain assumptions that we believe are reasonable
under the circumstances. The unaudited pro forma consolidated statement of
operations does not purport to represent what our results of operations would
actually have been had the transaction occurred on such date, nor does it
purport to project our results of operations for any future period.

       NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS

   The unaudited pro forma consolidated financial information is based on our
historical consolidated financial statements and those of our subsidiary,
GeneScreen, adjusted to give pro forma effect to our acquisition of GeneScreen.

   The unaudited pro forma consolidated statement of operations for the year
ended December 31, 1999 gives effect to the GeneScreen acquisition as if it
occurred on January 1, 1999. The unaudited pro forma adjustments set forth
below are based upon available information and assumptions that we believe are
reasonable under the circumstances. The unaudited pro forma consolidated
statements of operations do not purport to project our operating results for
any future period. The information set forth below should be read together with
the historical consolidated financial statements of Orchid and GeneScreen and
related notes included elsewhere in this prospectus.

(1)  Adjustment to reduce general and administrative expense for transaction
     related costs incurred by GeneScreen in connection with our acquisition of
     GeneScreen.

(2)  Adjustment to record the amortization of goodwill and other intangible
     assets on a straight line basis over their estimated useful lives. In the
     application of purchase accounting for our acquisition of GeneScreen, we
     allocated $42,900,000 of the net purchase price to intangible assets, as
     follows:

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

   The following discussion and analysis should be read with "Selected
Financial Data" and our consolidated financial statements and related notes
included elsewhere in this prospectus. This discussion in this prospectus
contains forward-looking statements that involve risks and uncertainties, such
as statements of our plans, objectives, expectations and intentions. The
cautionary statements made in this prospectus should be read as applying to all
related forward-looking statements wherever they appear in this prospectus. Our
actual results could differ materially from those discussed here. Factors that
could cause or contribute to these differences include those discussed in "Risk
Factors," as well as those discussed elsewhere. See "Risk Factors" and "Special
Note Regarding Forward-Looking Statements."

Overview

   We are engaged in the development and commercialization of genetic diversity
technologies, products and services. Since we began operations in March 1995,
we have devoted substantially all of our resources to the development and
application of a portfolio of products and services using our proprietary
biochemistry for scoring SNPs and microfluidics technologies for applications
in drug discovery, principally in the field of pharmacogenetics and DNA
synthesis.

   For the first three years of our existence, we were primarily focused on
developing our microfluidics technologies for applications in high-throughput
synthesis of small molecules under collaborative research programs with
SmithKline Beecham and Sarnoff Corporation. During this period, we derived most
of our revenue from payments from SmithKline Beecham. Revenue during these
early years fluctuated due to the timing of both work performed under the
contract with SmithKline Beecham and of earning milestone revenue. After
management and an independent third-party consulting firm conducted a strategic
review of our business strategy in the first half of 1998, we decided to apply
our research and development efforts to the fields of pharmacogenetics and DNA
synthesis. As a result of this review of our business focus, we acquired
substantially all of the assets of Molecular Tool, Inc. in September 1998, a
wholly-owned subsidiary of GeneScreen, Inc., for approximately $7.1 million in
cash, debt and equity securities. Molecular Tool's proprietary SNP-IT primer-
extension technology for scoring SNPs matched very well with our microfluidics
technologies that we developed earlier and has together formed the basis for
our current SNP technology, products and services.

   On December 30, 1999, we acquired GeneScreen, Inc. for a net purchase price
of $42.7 million consisting of a combination of cash and shares of our Series E
mandatorily redeemable convertible preferred stock, offset by the cancellation
of certain debt owed to GeneScreen. We included $28.5 million as a beneficial
conversion feature in the purchase price. The amount of the beneficial
conversion feature was calculated as the difference between the $11.75 per
share fair value of our common stock on December 22, 1999, the commitment date
which was the date of the merger agreement for the acquisition, over the $4.50
per share conversion price of the stock. GeneScreen is a company engaged in DNA
laboratory analysis for paternity, forensics and transplantation testing and
had revenues of approximately $13.7 million in 1999. GeneScreen analyzed over
290,000 specimens for the determination of paternity, which represented 70.6%
of their revenue in 1999. Forensic testing services, which represent a small
but growing segment of GeneScreen's revenue, represented 3.6% of GeneScreen's
revenue in 1999. In 1999, GeneScreen provided transplantation testing for over
71,000 bone marrow donors. Transplantation testing services represented 25.2%
of GeneScreen's revenue in 1999, most of which was related to a contract which
was not renewed. In connection with the acquisition of GeneScreen, we recorded
approximately $43.1 million of goodwill and other intangible assets, which we
will amortize over periods ranging from 4 to 15 years. As a result, our results
of operations during the next 15 years will be impacted by non-cash
amortization charges resulting from the GeneScreen acquisition which will range
from approximately $2.2 to $3.2 million per year.

   Most of our current activities and resources are directed toward
commercializing our SNP scoring products and services which apply our
proprietary SNP-IT primer-extension technology. We expect to recognize

                                       27
<PAGE>

revenues from the sale of both our SNPstream instrument systems and our SNPware
consumables. We also expect each SNPstream system we sell or lease will
generate a recurring revenue stream from the sale of our SNPware consumables.
We also provide, or plan to provide, a variety of genetic diversity services to
the pharmaceutical and biotechnology industry through our ultra high-throughput
MegaSNPatron facility.

   GeneScreen's established business in paternity testing, forensics and
transplantation supported our goal of building our business in genetic
diversity. We believe our SNP-IT and microfluidics technologies will be able to
improve the performance of GeneScreen's genetic testing laboratories. We plan
on using the clinically approved laboratories at GeneScreen to expand our SNP
scoring services to pharmacogenetics testing of patient samples in
pharmaceutical clinical trials. We also plan on using these laboratories to
conduct the SNP scoring for our planned direct-to-consumer SNP scoring service
which we will provide over the Internet.

   GeneScreen's DNA testing business is dependent upon contracts with various
states and counties to provide paternity testing. These contracts are generally
put out to bid by each respective state every one to three years. The contract
bidding process is highly competitive and the award varies from state to state.
Some states and counties award contracts solely based on the lowest price while
others use a scoring matrix to achieve the desired mix of price, quality and
service. GeneScreen derives its transplantation business through contracts on a
bid basis with the National Marrow Donor Program, a not-for-profit agency that
facilitates hematopoietic cell transplants through organizing volunteer donor
drives, maintaining a national donor registry and other educational services.
With the acquisition of GeneScreen, we expect to generate service revenue in
fiscal year 2000 and use GeneScreen's CLIA approved testing laboratories to
expand our genetic diversity testing business and services.

   Our ability to achieve profitability will depend in part on our ability to
successfully develop and commercialize our proprietary SNP scoring and
microfluidics technologies in the form of products and services for
pharmaceutical and biotechnology companies and research institutions. We
introduced our SNPstream 25K SNP-IT-based SNP scoring system, SNPware
consumables and related services in late 1999. We intend to develop additional
models of SNPstream instruments with lower throughput capabilities. Because our
proprietary SNP-IT primer-extension technology is very adaptable to other
hardware platforms, we intend to offer our SNPware kits for use on instruments
made or sold by other companies. Our collaboration with Affymetrix, Inc. is an
example of this platform propagation strategy.

   We based our proprietary SNP value creation strategy on the creation of
proprietary rights covering the identification of SNPs and their associations
to medically important attributes of patients. We intend to develop
intellectual property rights in this area through collaborations with members
of our Clinical Genetics Network, pharmaceutical and biotechnology companies.
We do not expect royalties from commercial sale or license of intellectual
property rights generated by using our technologies for at least several years,
if at all.

   Through December 31, 1999, we had recorded an aggregate of $9.8 million of
deferred compensation expense resulting from the granting of stock options to
employees, directors or consultants covering shares of common stock, which
stock options had exercise prices below the fair value of the underlying common
stock at the date of their grant. Net of prior amortization, net deferred
compensation of $7.9 million at December 31, 1999 will be amortized over the
vesting periods of the respective options, typically four years. In January and
February 2000, we issued 36,500, 679,400, 40,750 and 40,750 stock options at
exercise prices of $1.25, $6.00, $12.00 and at the per share price of this
offering, respectively, for which we will record deferred compensation of $4.2
million which will be amortized over the respective vesting periods of the
options. Included in the 679,400 options are 520,000 options granted to
executive officers at an exercise price of $6.00 per share for which we will
record deferred compensation of $3.1 million, which is included in the $4.2
million, and which will be amortized over the respective vesting periods. On
March 31, 2000, we granted 289,660 stock options at exercise prices of $12.00
for which we will record deferred compensation of $800,000 which will be
amortized over the respective vesting periods of the options. In addition, in
February 2000, we issued 855,000 performance based stock options at exercise
prices of $6.00 per share, including 600,000 options granted to executive
officers, for which compensation expense will be measured as the difference
between the fair value of our common stock at the time the performance criteria
is met and the exercise price and will be immediately recorded as compensation
expense.

                                       28
<PAGE>


   We anticipate recording total compensation charges resulting from the
amortization of the deferred compensation recorded as of December 31, 1999 and
for deferred compensation to be recorded for the January, February and March
2000 grants approximately as follows, in millions:

<TABLE>

           ----             ----                     ----                     ----                     ----
           <S>              <C>                      <C>                      <C>                      <C>
           $3.9             $3.5                     $3.0                     $2.3                     $0.2
</TABLE>

   Some of these amounts result from grants to consultants which are subject to
remeasurement at the end of each reporting period based upon the changes in the
fair value of the common stock until the consultant completes performance under
his or her respective option agreement. Also, certain grants of performance
based options have been made for which no deferred compensation expense has
been recorded and for which compensation expense will be measured at the time
the performance criteria is met.

   We have incurred losses since our inception and, as of December 31, 1999, we
had a total stockholders' deficit of $8.3 million, including an accumulated
deficit of $50.8 million. We anticipate incurring additional losses over at
least the next several years. We expect these losses to continue as we expand
the commercialization of our products and services to the research market and
we fully implement our proprietary SNP value creation business strategies. We
expect this expansion to result in increases in research and development,
marketing and sales, and general and administrative expenses. Payments under
strategic alliances, collaborations and licensing arrangements will be subject
to significant fluctuation in both timing and amount and therefore our results
of operations for any period may not be comparable to the results of operations
for any other period.

 Sources of Revenue and Revenue Recognition

   We have had, and expect in the future to have, several sources of revenue.
Prior to our acquisition of GeneScreen, we derived substantially all of our
revenue from research and development collaborations, technology grants and
awards from several governmental agencies. GeneScreen derives its revenue from
the performance of laboratory DNA testing services. In 1999, we derived our
first revenue from the sale and lease of our first commercial SNPstream
hardware systems, and commencing in 2000, we anticipate deriving increasing
amounts of revenue from the sale of SNPware consumables.

   In connection with the research and development collaborations that provided
the majority of our revenue in the early years of our corporate history, we
recognized revenue when related research expenses were incurred and when we
satisfied specific performance obligations under the terms of the respective
research contracts. Up front licensing fees obtained in connection with such
agreements are deferred and amortized over the estimated performance period of
the respective research contract.

   GeneScreen DNA laboratory and SNP testing services testing revenue is
recognized on an accrual basis at the time test results are reported. Deferred
revenue represents the unearned portion of payments received in advance of
tests being completed.

   To date, we have offered our SNPstream system hardware in two basic types of
transactions, either a purchase and sale or an operating lease. Revenue on the
sale of the hardware is recorded upon transfer of title and after we have met
all of our significant performance obligations. Revenue from lease transactions
is recognized on a straight-line basis over the term of the lease in accordance
with the lease agreement.

   We have only recently begun to record revenue from the sale of SNPware
consumables. Such revenue is recognized upon the transfer of title, generally
when the SNPware products are shipped to our customer from our facility.

Results of Operations

   Pro forma results discussed below give pro forma effect to our acquisition
of GeneScreen as if it were acquired on January 1, 1999.

                                       29
<PAGE>

 Years Ended December 31, 1999 and 1998

   Revenue. Revenue decreased to $1.8 million for the year ended December 31,
1999 from $2.8 million for the comparable period in 1998. The $1.0 million
decrease resulted primarily from a $2.7 million decrease in contract revenue
from SmithKline Beecham, which we offset by an increase in grant revenue of $.8
million and contract revenue from Motorola of $.8 million. On a pro forma
basis, revenue was $15.5 million for the year ended December 31, 1999.

   Research and Development Expenses. Research and development expenses consist
primarily of salaries and related personnel costs, fees paid to consultants and
outside service providers for chip development, material costs for prototype
and test units, and other expenses related to the design, development, testing
and enhancement of our products. We expense our research and development costs
as we incur them. Research and development expenses increased to approximately
$14.4 million for the year ended December 31, 1999 from approximately $7.6
million for the comparable period in 1998. We attributed the increase to
continued growth of research and development activities, including increased
personnel costs of $2.2 million and increased lab supplies and chemicals costs
of $1.8 million to support our technology program and development of our
initial products, higher operating expenses as a result of our move to a larger
facility in May 1999 of $0.6 million, increased non-cash expenses from equity
issuances for licensed technology of $1.0 million, and increased amortization
of deferred compensation of $0.6 million. On a pro forma basis, research and
development expenses for 1999 were not materially different from research and
development expenses in 1998. We expect research and development spending to
increase significantly over the next several years as we expand our research
and product development efforts.

   General and Administrative Expenses. General and administrative expenses
consist primarily of salaries and related expenses for executive, finance and
other administrative personnel, recruiting expenses, professional fees, legal
expenses resulting from intellectual property prosecution and protection, and
other corporate expenses including business development and general legal
activities. General and administrative expenses increased to approximately $9.6
million for the year ended December 31, 1999 from approximately $5.2 million
for the comparable period in 1998. The increase was primarily due to increased
compensation for general and administrative personnel of $1.0 million, higher
operating expenses as a result of our move to a larger facility in May 1999 of
$0.7 million, increased costs related to intellectual property prosecution and
protection and other professional services of $0.8 million and increased
amortization of deferred compensation of $0.9 million. We expect general and
administrative expenses to continue to increase over the next several years to
support our growing business activities, the commercialization of our products,
and due to the costs associated with operating as a public company. On a pro
forma basis, general and administrative expense was $17.8 million for the year
ended December 31, 1999. The increase in these expenses was related to
amortization of goodwill and other intangibles of $3.2 million and $5.0 million
of costs related to the additional staffing to operate and to manage GeneScreen
DNA testing business.

   Acquisition of in-process research and development. Acquisition of in-
process research and development amounted to $2.4 million in 1998 arising from
our acquisition of certain Molecular Tool assets in 1998, including an
in-process research and development component which we immediately charged to
expense upon acquisition. We did not incur any comparable charge in 1999.
Please see Note 2 to the Notes to Consolidated Financial Statements for a
discussion of this charge.

   The principal corporate activity of Molecular Tool at the date of
acquisition was the continued technical development of our product programs in
the areas of SNPware consumables, MegaSNPatron services, SNPstream hardware
systems and SNP-IT Chips. At the date of acquisition, none of the products or
services under development by Molecular Tool, Inc. had achieved technological
feasibility or had been sold on the market. Substantial risks and significant
uncertainty still existed concerning the remaining course of technical
development. Key development risks for this product included validation
testing, engineering of stability into the critical reagents to permit their
use in the field, and developing the means of scaling-up manufacturing of the
reagents and other elements of the product for eventual sale. We identified and
proposed the SNP-IT Chips

                                       30
<PAGE>


as a new technology development area at the time of the acquisition. However,
Molecular Tool, Inc. had not yet demonstrated major components of the chip as
feasible. These components have required and will continue to require
substantial investment. Molecular Tool, Inc. had not yet shown the following
elements of these components to be feasible: chip materials fabrication and
biocompatibility; method and composition of bioactive surface preparation; and
method and composition of optical detection systems compatible with chip
design. The MegaSNPatron services, while currently more commercially advanced
than the SNP-IT Chips, required additional development and feasibility
demonstration in several key areas, including the method and composition of the
bioarray components; the ability to capture and process results data from the
MegaSNPstream process; and the composition of stable, viable, and cost
effective reagents for the tests. In the case of the SNPstream hardware
systems, development of the analysis machine was largely complete but was still
expected to face engineering challenges before ultimate completion. We faced
challenges in our efforts to successfully commercialize our SNPstream hardware
and SNPware reagents such as the feasibility of adapting an off-the-shelf
robotic system as the SNPstream platform; development of software systems for
data management; and development and validation of viable, stable and cost
effective reagents usable in the SNPware kits. An overall risk facing these
projects was the potential development of competing technologies to facilitate
cost reduction in genetic assays prior to marketing the Molecular Tool
products. Accordingly, a significant portion of the purchase price was
allocated to in-process research and development. These product candidates will
significantly impact future results of operations and cash flows.

   The primary valuable elements of the product candidates were separated into
base technology, supporting patents, and the element associated with in-process
research & development. The base technology and patent elements were separately
valued and reported in the acquisition balance sheet. The valuable elements
qualified to receive treatment as in-process research and development were
separately valued as such.

   The remaining development cost and time required to develop the project
candidates into commercially viable products as of December 31, 1999 are as
follows: $1.5 million through 2003 for SNP-IT Chips and $800,000 through 2001
for MegaSNPatron services. The SNPware consummables, and SNPstream hardware
systems are currently commercial products.

   Material risks affecting the timely completion and commercialization of the
products included the ability to secure raw materials and material supply
agreements for our SNPware kits and MegaSNPatron services, including dyes and
enzymes necessary for the performance of our SNPware kits and services, and
reliance on the development of outside technology for optical components and
some aspects of robotic instrumentation from our SNPstream OEM. The remaining
development cost and time for these products reflect, in part the acquisition
through supply agreement, development and validation of the raw materials
needed for commercialization. Additionally the remaining development cost and
time reflects, in part, the identification, validation and development of the
technologies external to us needed to select our SNP-IT technology. An
additional material risk affecting commercialization was the presence of
competing technologies.

   Interest Income. Interest income consists of income from our cash and short-
term investments. Interest income decreased to $.2 million for the year ended
December 31, 1999 from $.9 million for the comparable period of 1998. This $.7
million decrease resulted from a lower average cash and short-term investment
balance due to cash used in operating activities.

   Interest Expense. Interest expense increased to $6.2 million for the year
ended December 31, 1999 from $.1 million in the comparable period of 1998. This
$6.1 million increase resulted substantially from interest on the bridge notes
which converted into Series E mandatorily redeemable convertible preferred
stock in December 1999 of $0.5 million, interest on the convertible note
payable to GeneScreen which we cancelled in the GeneScreen acquisition of $0.2
million, and interest attributable to warrants issued in connection with our
bridge financing of $5.2 million and borrowings on our line of credit in 1999
of $0.2 million.

   Net Loss. Due to the factors discussed above, our net loss was $28.2 million
for the year ended December 31, 1999 compared with a net loss of $11.5 million
for the comparable period in 1998.

                                       31
<PAGE>

 Years Ended December 31, 1998 and 1997.

   Revenue. Revenue decreased to $2.8 million for the year ended December 31,
1998 from $3.8 million for the comparable period in 1997. The $1.0 million
decrease resulted from a decrease in contract revenue recognized from
SmithKline Beecham.

   Research and Development Expenses. Our research and development expenses
decreased to $7.6 million for the year ended December 31, 1998 from $10.8
million for the comparable period in 1997. The decrease of $3.2 million was due
to a reduction in our expenditures at Sarnoff Corporation including expenses
recorded in 1997 related to an obligation under the SmithKline Beecham contract
which did not have a corresponding charge in 1998.

   General and Administrative Expense. General and administrative expenses
increased to $5.2 million for the year ended December 31, 1998 from $2.9
million for the comparable period in 1997. The $2.3 million increase was
primarily due to increased costs of $0.5 million resulting from the hiring of
additional personnel to support our growing business activities, increased
professional services fees of $1.2 million and increased facility charges of
$0.2 million.

   Acquisition of in-process research and development. Acquisition of in-
process research and development was $2.4 million for the year ended December
31, 1998 resulting from our acquisition of certain Molecular Tool assets in
1998, including an in-process research and development component which we
immediately charged to expense upon acquisition. We did not incur any
comparable charge in 1997.

   Interest Income. Interest income increased to approximately $.9 million for
the year ended December 31, 1998 from approximately $0 for the comparable
period in 1997. This $.9 million increase resulted from a higher average cash
and short-term investment balance due to the sale of Series C mandatorily
redeemable convertible preferred stock in a private placement in December 1997
and March 1998.

   Net loss. Due to the factors discussed above, our net loss was $11.5 million
for the year ended December 31, 1998 compared to $9.9 million for the
comparable period in 1997.

Liquidity and Capital Resources

   Since our inception, we have financed our operations primarily through
research and development funding from collaborative partners and two private
placements of equity securities that closed in March 1998 and January 2000 with
aggregate net proceeds from the private placements of approximately $102
million. The sale of the Series E mandatorily redeemable convertible preferred
stock in December 1999 resulted in a $44,554,000 beneficial conversion feature
which is included in net loss allocable to common stockholders in 1999. The
closing of Series E mandatorily redeemable convertible preferred stock in
January 2000 will result in an additional $29,574,000 beneficial conversion
feature which will increase net loss allocable to common stockholders and net
loss per share allocable to common stockholders in the first quarter of 2000.
In December 1998, we obtained a secured $6.0 million equipment line of credit,
for the purchase of plant and equipment at our corporate headquarters and
research and development laboratories. At December 31, 1999, this funding
commitment expired and we had borrowings of $4.6 million outstanding under this
facility. We lease our corporate and primary research facility under an
operating lease which expires in 2008.

   In June 1999, we completed a bridge financing in which we issued convertible
promissory notes in the aggregate principal amount of approximately $7.6
million. The principal amount of these notes and all accrued interest thereon
were automatically converted into shares of Series E mandatorily redeemable
convertible preferred stock in December 1999 in connection with the sale of
Series E mandatorily redeemable convertible preferred stock.

   In November 1999, we completed a bridge financing in which we issued a
senior convertible promissory note in the original principal amount of
approximately $2.3 million to Affymetrix, Inc. The principal amount of

                                       32
<PAGE>

this note and all accrued interest thereon also automatically converted into
shares of Series E mandatorily redeemable convertible preferred stock in
December 1999 with the related shares being issued in January 2000.

   Net cash used in operations for the year ended December 31, 1999 was
approximately $15.4 million compared with approximately $11.5 million for the
comparable period in 1998. Non-cash charges in 1999 included compensation
expense of $1.6 million and research and development expense from the issuance
of equity securities of $1.8 million, depreciation and amortization expense of
$1.4 million and interest expense related primarily to warrants issued in
connection with our 1999 bridge financing and accrued interest on the bridge
notes which converted into Series E mandatorily redeemable preferred stock of
$6.0 million. Investing activities included $8.2 million in cash used during
the year ended December 31, 1999 for leasehold improvements and equipment
purchases for our new facility in Princeton, New Jersey.

   Working capital increased to approximately $27.3 million at December 31,
1999 from approximately $5.8 million at December 31, 1998. The increase in
working capital was primarily due to our Series E mandatorily redeemable
convertible preferred stock financing in December 1999.

   At February 29, 2000, we held cash and cash equivalents of approximately
$57.4 million. We believe that our cash reserves, expected short-term revenue,
and the net proceeds of this offering will be sufficient to fund our operations
through at least the next 18 months. We may need to access the capital markets
for additional financing to operate our ongoing business activities.

   As part of our transition from a business model based on microfluidics
technologies to one based on SNP scoring technologies, on April 13, 2000 we
amended our License and Option Agreement with Sarnoff by making a single
payment of approximately $3.0 million, issuing 250,000 shares of common stock
and delivering a five-year warrant to purchase 75,000 shares of our common
stock at the initial public offering price, or at $12 per share if we have not
closed an initial public offering by April 13, 2001. Previously on February 2,
2000, we issued 100,000 shares of common stock to Sarnoff as an advance on the
issuances which would be owed in December 2000 for the two option fields
previously exercised under the License and Option Agreement. As the licensed
technology has not reached technological feasibility and has no alternative
uses, the cash payment of approximately $3.0 million and the fair value of the
equity securities of approximately $4.8 million will be charged to research and
development expense in 2000.

   As of December 31, 1999, our net operating loss carryforwards were
approximately $40.0 million and $44.0 million for federal and state income tax
purposes, respectively. If not utilized, our federal and state tax loss
carryforwards will begin to expire in 2003. Utilization of our net operating
losses to offset future taxable income, if any, may be substantially limited
due to "change of ownership" provisions in the Internal Revenue Code of 1986.
We have not yet determined the extent to which limitations may have been
triggered as a result of past or future financings, including this offering.
This annual limitation may result in the expiration of certain net operating
losses prior to their use.

   We cannot assure you that our business or operations will not change in a
manner that would consume available resources more rapidly than anticipated. We
also cannot assure you that we will not require substantial additional funding
before we can achieve profitable operations. Our capital requirements depend on
numerous factors, including the following:

  .  our ability to enter into strategic alliances or make acquisitions;

  .  regulatory changes and competing technological and market developments;

  .  changes in our existing collaborative relationships;

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

                                       33
<PAGE>

  .  the purchase of additional capital equipment;

  .  the development of our SNPstream and DNAstream and software product
     lines and associated reagent consumables;

  .  the development of our SNPware consumables and kits;

  .  the success rate of establishing new contracts, and renewal rate of
     existing contracts, for DNA testing services in the areas of paternity,
     forensics and transplantation;

  .  the progress of our existing and future milestone and royalty producing
     activities; and

  .  the availability of additional funding, if necessary, and if at all, on
     favorable terms.

Disclosure About Market Risk

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

Inflation

   We do not believe inflation has had a material impact on our business or
operating results during the periods presented.

Recently Issued Accounting Standards

   In December 1999, the staff of the Securities and Exchange Commission issued
a Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements" ("SAB 101"). SAB 101 summarizes certain of the staff's views in
applying generally accepted accounting principles to revenue recognition in
financial statements, including the recognition of non-refundable fees received
upon entering into arrangements. Our revenue recognition policies are
consistent with the provisions of SAB 101 and our financial statements reflect
this policy for all periods presented.

                                    BUSINESS

Overview

   We are engaged in the development and commercialization of technologies,
products and services designed to measure and use information related to
genetic diversity. We expect our proprietary technologies will significantly
enhance the way the companies generate information about single nucleotide
polymorphisms, or "SNPs," the most common form of genetic diversity. The
pharmaceutical and medical communities can use genetic diversity information to
facilitate the development of highly specific and efficacious drugs, to improve
the effectiveness of existing drugs, and to increase the likelihood of success
of tissue transplants. Our proprietary technologies also have other commercial
applications outside of the healthcare field, including forensics and paternity
testing, as well as improved crop development and livestock breeding programs.

History

   For the first three years of our existence, we were primarily focused on
developing our microfluidics technologies for applications in high-throughput
synthesis of small molecules under collaborative research programs with
SmithKline Beecham and Sarnoff Corporation. After our management and an
independent third-party consulting firm conducted a strategic review of our
business strategy in the first half of 1998, we decided to apply our technology
to the fields of pharmacogenetics and DNA synthesis. As a result of this review
of our business focus, we acquired substantially all of the assets of Molecular
Tool, Inc., a wholly owned subsidiary of GeneScreen, Inc., in September 1998.
Molecular Tool's proprietary SNP-IT primer-extension technology for scoring
SNPs matched very well with our microfluidics technologies that we had
developed earlier and has together formed the basis for our current SNP
technology, products and services.

Background

   Genetic information provides a basis for understanding biological and
medical functions in organisms. In recent years, scientists have begun to
analyze large portions of deoxyribonucleic acid, or DNA, to determine the
sequence of nucleotide bases in DNA within the human genome and within the
genomes of plant and animal species. The Human Genome Project and other major
genetic research programs are identifying hundreds of millions of DNA base
sequences. These studies are expected to be completed within the next few
years.

   The first phase of the genomics revolution has centered around sequencing
significant portions of DNA within the human genome. We believe the next phase
of the genomics revolution will involve the identification of genetic variation
within the genome from person to person resulting from differences, or
polymorphisms, in these DNA sequences.

 The Impact of Genetic Variation

   Pharmacogenetics is the study of the impact of genetic variation on the
efficacy, pharmacology and toxicity of a drug. As scientists and researchers
have acquired a greater understanding of genetic variation, they have realized
that the effect a drug has upon an individual is often a function of that
individual's unique genetic sequence. Genetic variation may indicate why some
individuals contract certain diseases and others do not and may also determine
why two individuals respond differently to the same drug. Typically,
pharmaceutical companies develop drugs to interact with a single version of a
given protein or receptor. Accordingly, a drug may only be effective in
individuals who carry the specific protein or receptor for which the drug was
designed. Individuals who, because of genetic variation, have a slightly
modified version of these proteins or receptors, or the proteins involved in
the metabolism of the drug, may not respond to the drug or may experience
adverse side effects.

                                       35
<PAGE>

   We expect that the methods used by the pharmaceutical industry to develop
new drugs and to improve existing drugs will undergo a fundamental
transformation to take genetic variation into account. However, the usefulness
of genetic variation information is not limited to drug development. In fact,
genetic variation can play a significant role in all stages of drug discovery
and development. Pharmaceutical companies can improve drugs already on the
market by using genetic variation information to select the best drug for a
particular patient. Genetic variation information may also be used to improve
the success of organ and bone marrow transplantations by matching the
compatibility of donors to recipients as well as for paternity testing,
forensics testing and for agricultural and livestock breeding programs.

 SNPs: A Key Indicator of Genetic Variation

   DNA sequences contain a variety of known polymorphisms. The most common form
of polymorphism involves a change in a single nucleotide base and is called a
single nucleotide polymorphism, or SNP. Because SNPs are the most common type
of polymorphism, they can have significant effects on both susceptibility to
disease as well as drug response. As a result, the biotechnology and
pharmaceutical industries have recently focused attention on the discovery of
SNPs. For example, in 1999, a group of leading pharmaceutical companies formed
The SNP Consortium Ltd. for the primary purpose of discovering new SNPs and
making them publicly available. The SNP Consortium members include: The
Wellcome Trust, Amersham Pharmacia Biotech, AstraZeneca, Aventis, Bayer,
Bristol-Myers Squibb, F. Hoffmann-LaRoche, Glaxo Wellcome, IBM, Motorola,
Novartis, Pfizer, Searle, and SmithKline Beecham.

   The increased focus on the discovery of SNPs highlights the important
distinction between SNP discovery and SNP scoring. SNP discovery refers to the
identification of the specific location in a gene where there is variability in
a single nucleotide base across a population. By contrast, SNP scoring refers
to the measurement of the presence or absence of a particular SNP in the
genetic sequence of a particular individual. We believe that the mere discovery
of SNPs has not been of significant value in the treatment of disease. Unlike
SNP discovery, SNP scoring focuses on what we believe is a compelling and
potentially more valuable opportunity of correlating a given SNP or combination
of SNPs with important medical attributes. Recently reported data indicates
that there are in excess of one million SNPs in each individual. While some of
these SNPs have obvious and immediate medical relevance, the significance of
the vast majority of SNPs is currently unknown. We believe the commercial value
of SNPs will be realized by identifying SNPs with medical relevance by
performing SNP scoring studies on hundreds of thousands of SNPs in hundreds of
thousands of individuals.

   As the Human Genome Project nears completion, the number of identified SNPs
will increase dramatically. Scientists and researchers will require SNP
association studies to find the potential relevance of identified SNPs to human
health. As a result, we expect the demand for SNP scoring to increase
significantly over the next few years. This increase in demand will be driven
not only by a small group of dedicated laboratories conducting large-scale
experiments, but also by a large number of smaller research and clinical
laboratories conducting a more diverse set of experiments. To find the subset
of SNPs that occurs with the greatest frequency in human disease or that are
potentially responsible for variations in drug response, hundreds of millions
of SNP scores must be made and correlated with health and other features of
interest. Research and clinical laboratories will require the use of a highly
accurate, high-throughput SNP scoring technology that can be implemented at a
competitive cost to find these valuable SNPs.

   The SNP Consortium has announced its intention to identify a set of
approximately 300,000 SNPs by the end of 2001. If research laboratories were to
score all of these SNPs in a group of 1,000 patients, they would require large-
scale experiments consisting of over 300,000,000 individual SNP scores. Since
there are many research laboratories currently conducting research on SNPs, we
estimate they will require the performance of billions of SNP scores over the
next few years and potentially a thousand-fold more over the next decade. Since
performing SNP scoring using conventional sequencing methods can cost several
dollars per SNP score, these studies would be cost-prohibitive without further
technological advancement.

 Traditional Methods of SNP Analysis and Their Limitations

   Current methods for discovering SNPs rely on DNA sequencing, which is
currently conducted by large dedicated laboratories using automated
electrophoresis instruments. While DNA sequencing is an efficient SNP discovery
tool, it is expensive and complex when used to conduct SNP scoring.

   Researchers have developed variations upon standard DNA sequencing methods,
such as DNA hybridization. DNA hybridization relies upon the principle that a
unique piece of DNA will hybridize most strongly to its exact complement as
opposed to a complement containing a SNP. A significant problem with
hybridization as a DNA sequencing method, however, is that it requires ideal
testing conditions. Slight changes in temperature, salt concentration or DNA
composition will dramatically affect the reliability of the hybridization
reaction. As a result, some commercial tests based on hybridization require ten
or more repetitive analyses for every SNP scored. While various commercial
variations of the hybridization technique have improved the reliability of
hybridization, the technique remains complex and costly.

 SNP Scoring Systems

   SNP scoring systems typically contain two basic elements: an instrument
platform or "hardware" component and a biochemistry or "wetware" component. The
hardware component, which is the instrument platform where the SNP scoring
takes place, typically consists of a means of detection, such as fluorescence,
mass spectroscopy or optical density; a separation apparatus such as
electrophoresis, beads or multi-well plates; and a liquid dispensing apparatus
having such features as pipetting or microfluidics. The wetware component,
which is a specifically designed set of biochemical reagents, conducts the
test, or assay, that recognizes the SNP at the molecular level as being present
or absent at its expected location. The actual recognition, or scoring of the
SNP, takes place by having molecules bind or react with or near the location of
the SNP in a test tube or other suitable chamber. Since the wetware component
consists of consumable reagents designed for a specific set of procedures and
packaged within a single kit, multiple kits must be purchased for multiple SNP
analyses.

   There are certain key criteria of both hardware and wetware components that
contribute to the success of the overall SNP scoring system. For the hardware
component, these criteria include throughput, cost, flexibility, automation and
ease of use. For the wetware component, these criteria include the following:

  . Accuracy. The sensitivity of the biochemistry wetware in accurately
    recognizing and scoring a single SNP or a group of SNPs in a large group
    of samples.

  . Flexibility. The adaptability of the biochemistry wetware for use on many
    different instrument platform hardware systems having various degrees of
    automation and detection methods.

  . Cost. The cost of the reagents and the labor used to perform each SNP
    score.

  . Robustness. The ability of the assay to perform well under a variety of
    experimental conditions and the user-friendliness of the protocol
    required to conduct the test.

  . Scalability. The ability of the biochemistry wetware to function through
    a range of production size requirements from single sample tests to large
    scale mass production.

   Because each SNP scoring customer will have specific system requirements,
the ideal SNP scoring system should be capable of addressing all of the
criteria described above.

   With the increased focus of the biotechnology and pharmaceutical industries
on the value of SNPs and the increase in the number of discovered SNPs, there
is a pressing need for a fast and flexible SNP scoring system that can score
SNPs with a higher level of accuracy and at a lower cost than is achievable
with current methods.

Orchid's Unique Solutions

 Our Proprietary Wetware -- SNP-IT

   We conduct SNP scoring using our proprietary SNP-IT primer-extension
technology. SNP-IT primer extension is a method of isolating the precise
location of the site of a suspected SNP and utilizing the inherent accuracy of
DNA polymerase to determine the presence or absence of the SNP. In order to
conduct SNP-IT primer extension, we first bind a specially synthesized DNA
primer to the sample DNA to expose the DNA site of interest where a SNP may be
present. We then add DNA polymerase, a naturally occurring molecule that
accurately and reliably inserts the appropriate complementary base to a chain
of DNA, to extend the DNA chain by one base at the suspected SNP location. We
then use one of several conventional methods, including fluorescence, optical
density, electrophoresis and mass spectroscopy, to detect this single base
extension. The result is a direct read-out method of detecting SNPs that
creates a simple binary "bit" of genetic information representing the presence
of a SNP in a DNA sample.

   We believe our proprietary SNP-IT primer-extension technology has certain
advantages over other alternative SNP scoring technologies because it can
produce accurate results in less than ideal conditions. Further, our SNP-IT
primer-extension technology uses experimental steps and instruments already
familiar to technicians and scientists in the life sciences field. SNP-IT
primer extension is distinct from other currently available SNP scoring
technologies in the following ways:

  . Accuracy. We believe our proprietary technologies permit users to realize
    higher levels of accuracy without incurring the time and expense of
    conducting repetitive analyses of the same SNP. Unlike most alternative
    hybridization-based methods, our SNP scoring technologies rely on the
    inherent accuracy of DNA polymerase. The use of DNA polymerase enables
    our SNP-IT primer-extension technology to achieve the accuracy and
    reproducibility of DNA sequencing, while lowering costs and reducing
    complexity. Since a SNP scoring technology that is susceptible to even a
    one percent error rate could double the sample requirements and
    significantly increase the costs of a clinical trial, the degree of
    accuracy of our SNP scoring technologies should improve the design and
    reduce the cost of entire clinical studies.

  . Flexibility. Our biochemistry wetware component is compatible not only
    with our hardware platform, but also with the 100,000 other instrument
    systems we estimate are already installed around the world. Unlike the
    wetware components of competing systems, we may apply our wetware to a
    wide range of formats and systems including: arrays, gels and beads, as
    well as mass spectroscopy and optical systems. We believe the flexibility
    of our SNP-IT primer-extension technology may permit us to provide our
    products and services to customers who use different platforms with a
    combination of price and performance tailored to their needs.

  . Cost. We expect the use of our SNP-IT primer-extension technology for SNP
    scoring will reduce the amount of data required to be analyzed when
    conducting SNP association studies relative to current alternative
    methods of primer extension. We believe eliminating the need for
    repetitive SNP scoring tests will reduce costs associated with both
    clinical trial sample collection and SNP scoring.

  . Robustness. We believe SNP-IT primer-extension technology provides
    accurate results over a wide range of testing conditions and is less
    vulnerable to failure or false results if testing conditions are not
    ideal.

  . Scalability. We believe we are unique in our ability to scale our SNP
    technologies to meet the needs of potential customers who will require
    tests ranging from a single SNP per sample to hundreds of thousands of
    SNPs on thousands of samples.

There are, however, elements of our SNP-IT technology which may be perceived as
limitations by our potential customers. These limitations include:

  . Reliance upon third party prepared primers. The accuracy of results that
    customers may achieve with our SNP-IT technology and our SNPstream
    instruments relies upon the accuracy and quality of primers

                                       38
<PAGE>


   prepared by these customers or third parties. If primers are not properly
   prepared, our technology may not produce accurate results. Our competitors
   who use other technologies such as hybridization similarly rely on primers
   prepared by third parties.

  . Adoption of technology. A number of potential customers in our industry
    may be slow to adopt our SNP-IT technology in part, because it has not
    achieved widespread use or proof in the market and because these
    potential customers are not aware of the advantages of our technology.
    Many of our competitors offer more widely recognized technology that may
    be selected by customers because of the familiarity they may have with
    our competitor's technology.

  . Reliance upon third party sequence information. Our SNP-IT technology
    relies on having complete sequence information for the bases surrounding
    a potential SNP site in order to design a primer that will bind with that
    SNP. By contrast, our competitors who are engaged in the discovery of
    SNPs through the use of DNA sequencing do not require sequence
    information about the bases surrounding a potential SNP site.

 Our Complementary Technologies

   We also have a portfolio of microfluidics technologies which we are
applying to the field of SNP scoring. We plan to use our microfluidics systems
to increase the throughput and decrease the costs of SNP scoring. We also plan
to use our microfluidics systems to synthesize DNA for use as primers in SNP
scoring. We can manufacture our primer arrays for use in a wide variety of
formats, including industry standard 384-well plates in our MegaSNPatron
facility and arrays compatible with other DNA chip systems. This should allow
us to format SNP arrays and tailor them rapidly on a project-by-project basis
and give us the ability to produce DNA arrays on demand. By applying these
technologies, we believe we will be able to increase the throughput and reduce
the cost of SNP scoring to pennies per score.

   We have also developed additional chemistries and technologies which
augment our SNP scoring capabilities, including detection methods, target
preparation methods, signaling chemistries, surface chemistries, SNP scoring
algorithms, primer design software, data management tools and primer extension
permutations. We have designed proprietary algorithms which allow for the
automated selection of important SNP patterns associated with the scoring of
inherited SNPs. Many of our chemistries and technologies involve novel uses of
instrumentation, software and technologies that still require validation in
commercial applications. Many alternative chemistries and technologies
currently in use have been demonstrated to be commercially viable.
Nonetheless, rapid changes in the development of technology in the field of
genetic diversity can quickly make genetic diversity technologies, including
our own, obsolete. We intend to continue to pursue new chemistries and
technologies which improve our core technology position in SNP scoring and
analysis.

Genetic Diversity Markets

   Due to the key role of SNPs as indicators of genetic diversity, we believe
SNP scoring will have significant applicability in all stages of drug
discovery and development. In each of these stages, we believe SNP scoring can
provide significant value for our customers and create market opportunities
for us described below:

 The Use of SNP Scoring in Drug Discovery

  . Target Identification. Researchers can use correlations between
    individuals with a given disease and SNPs to identify candidate genes
    that are related to the disease. These candidate genes can then serve as
    candidate targets for new drug development.

  . Target Validation. A target containing many SNPs is likely to be a poor
    target for traditional drug discovery since too much variability may lead
    to a lack of uniform response in a patient population. Researchers can
    use SNP studies to validate candidate targets by either taking into
    account the target's variability or by eliminating targets with excessive
    variability at an early stage of the drug discovery process.

  . Lead Identification. Pharmaceutical companies can identify lead compounds
    which act not only on the proteins encoded by the target gene, but also
    the proteins encoded by the SNP variants of the gene. In this manner,
    they can identify lead compounds that act on multiple versions of a
    target protein.

                                      39
<PAGE>

  . Lead Validation. Pharmaceutical companies can conduct biological assays
    on lead compounds against SNP variants of a given protein, thereby
    validating a lead candidate.

 The Use of SNP Scoring in Drug Development

  . Lead Optimization. Pharmaceutical companies can use studies on known SNP
    variants of targets to improve existing drugs by seeking broader efficacy
    over larger populations with genetic variations. They can also use SNP
    scoring to re-evaluate and modify drugs that previously failed or that
    have been dropped from the market through evaluation of efficacy on
    specific SNP variants of drug targets.

  . Preclinical Testing. Studies with model systems to correlate drug
    response or lack of response and metabolism to known SNPs in the target
    or in related enzymes can yield better efficacy and permit more accurate
    safety predictions for a drug.

  . Clinical Trials. Pharmaceutical companies may select patients for
    clinical trials based on the presence or absence of SNPs known to be
    associated with drug response. Our technologies may reduce the duration
    and expense of clinical trials through the use of SNP scoring in smaller
    patient populations.

 The Use of SNP Scoring in Drug Marketing

  . Market Extension. Pharmaceutical companies can use SNP scoring in
    marketing programs to expand or extend markets of an existing drug to new
    patient groups based on SNP variants. This may lead to label extensions
    and longer commercial lives for existing compounds based on patient SNP
    type. In addition, these companies may use SNP scoring to exclude
    patients that are more likely to experience toxicity when treated with a
    certain drug. This should permit drugs to remain on the market for a
    longer period of time.

  . Generic Drugs. Pharmaceutical companies can use SNP scoring to discover
    novel uses of existing non-proprietary drugs.

  . Drug Revival. Pharmaceutical companies can use SNP scoring to bring drugs
    which previously failed due to adverse drug response or lack of response
    in a given indication back to the market for different indications or for
    use on better defined populations.

 The Use of SNP Scoring and Other Polymorphism Analyses in Healthcare Delivery

  . Clinical Diagnostics. Healthcare providers can use SNP scoring in patient
    testing for disease diagnosis or in determining the appropriate medical
    treatment for a patient.

  . Drug Selection. Healthcare providers can use SNP scoring to tailor
    formulations of drug treatments selected specifically for a patient
    having a unique set of SNPs. This could revolutionize drug prescription,
    significantly reducing erroneous or ineffective prescriptions. They may
    also use tailored formulations to develop more cost-effective formularies
    for managed care systems.

  . Medical Treatment Selection. Healthcare providers can use SNP scoring not
    only for drug selection but also to modulate drug dosage and to select
    non-pharmaceutical treatment, such as surgery, in cases where drugs may
    not be effective in a particular patient. We expect the reduction of the
    time required to identify an effective treatment will improve medical
    outcomes.

  . Transplantation Matching. Genetic variability in genes plays a key role
    in the success of transplantation therapy. The ability to rapidly and
    accurately match donated tissues to recipients through polymorphism
    matching has become increasingly important.

 Potential Impact of SNP Scoring on Our Prospective Markets

   The market potential for SNP scoring is a function not only of the variety
of different markets as described above but also of the impact of our SNP
scoring technologies on each of these markets. We describe the impact of new
and expanding uses of SNP scoring as the lifecycle of a SNP, consisting of the
following five stages.

                                       40
<PAGE>

   Stage 1: Discovery. Discovery of a SNP, typically through high-throughput
DNA sequencing.

   Stage 2: Confirmation. Confirmation that the suspected SNP is indeed a SNP
and not a sequencing mistake or rare mutation. This is accomplished by scoring
the SNP on hundreds of patients, plants or animals to determine its frequency
of occurrence.

   Stage 3: Association. Association of the confirmed SNP with the occurrence
of an adverse drug response, the lack of response to a drug or perhaps the
presence or absence of a disease through SNP scoring on a set of patient
samples grouped by medical attributes. In this manner, healthcare providers can
use SNP associations to determine the optimal drug selection for each patient
SNP type.

   Stage 4: Clinical Trials. Use of the knowledge of the presence or absence of
one or more SNPs to predict or improve the outcome of clinical trials.

   Stage 5: Diagnostic Testing and Industrial Application. Use of SNPs in the
clinical diagnostic testing of a patient to determine appropriate drug or
alternative treatment or in industrial applications.

   Each of these stages of the SNP lifecycle represents a separate business
opportunity with unique market dynamics and product or service requirements. As
a SNP progresses through this lifecycle, the throughput requirements at any
given laboratory for scoring this SNP may decrease. However, we expect the
number of laboratories performing SNP scoring in these later stages to increase
substantially. For example, it may take a laboratory with a throughput of a
million SNPs per day to identify the one specific SNP from a potential pool of
several thousand that can predict the response to a specific drug. In order to
make such association studies commercially viable, the laboratory would
probably want to use a SNP scoring technology such as SNP-IT primer extension,
that can provide accurate results without the need for repetitive testing. Once
a SNP progresses through the SNP association stage, that one SNP might find its
way into thousands of clinical laboratories performing tests on a few hundred
patients a day in order to complete clinical trials or diagnostic testing.
Thus, as the field of genetic diversity matures over the next few years, we
expect that researchers will use more and more SNPs in a larger number of
smaller laboratories such as clinical laboratories. Following the completion of
the sequencing of the human genome and the progression of many SNPs through the
early stages of the SNP lifecycle, we expect that our SNP-IT primer-extension
technology, which can adapt to existing diagnostic testing instruments, will
have significant market appeal.

 Industrial Applications of Genetic Diversity

   Genetic diversity also has many commercial and industrial applications.
State and other government agencies can use information related to genetic
diversity between individuals to determine identity and paternity. For example,
we can test DNA material collected from a crime scene to determine if a
particular individual was involved in the crime. Similarly, we can match the
DNA of a child to that of the mother and the purported father to determine
unambiguously the actual parents of the child. These two applications have
revolutionized forensics and child support enforcement. We also test DNA for
likely compatibility of organs or tissues for transplantation between
individuals. Our technologies enable us to screen large numbers of potential
donors for compatibility. We estimate that the market size for DNA testing in
these areas is more than $100 million per year.

   As with humans, genetic diversity in plants and animals results in
differences between species as well as differences in characteristics within
the members of given species. For example, plants have genetic variations
responsible for differences in crop yield as well as product size and flavor.
Animals also have genetic variations responsible for traits such as fertility
and resistance to disease. Agricultural companies and livestock breeders can
optimize traditional plant hybridization and breeding programs by using genetic
variation information to more rapidly attain desired quality traits of plants
and animals without engaging in genetic engineering.

Our Business and Commercialization Strategy

   Our objective is to become the premier provider of instruments, consumables,
services and technologies for SNP scoring and other genetic diversity tests.
The key elements of our strategy to achieve this objective include the
following:

 Rapid Commercialization

   We intend to rapidly commercialize our growing line of instruments,
consumables and services for SNP scoring. Our product lines currently include
our SNPstream hardware instruments, our SNPware wetware consumables and our
high-throughput MegaSNPatron facility for SNP scoring services. We intend to
expand our existing products and services to offer a wide range of performance
options.

   We currently sell SNPware consumables for use in SNP scoring and provide
non-exclusive, one-time use licenses of our SNP-IT primer-extension technology
in connection with each sale solely for the purpose of performing SNP scoring
using the quantity of samples and SNPs contained in each kit. We also expect to
generate substantial recurring revenue from the sale of our SNPware consumables
to purchasers of our SNPstream hardware systems.

   We also intend to expand the market for our proprietary SNP scoring
biochemistry wetware through our platform propogation strategy by offering it
for use on instruments made and sold by other companies. We expect to implement
this strategy in the third quarter of 2000 by selling SNPware consumables and
kits directly to the existing customer base of such companies. In addition, we
will continue to develop, manufacture and supply kits directly to instrument
companies to take advantage of their existing marketing and distribution
channels. Our collaboration with Affymetrix is an example of this strategy. We
also intend to form marketing distribution relationships to enhance the
distribution of our products. We believe our proprietary biochemistry
underlying our wetware is flexible enough to be adapted to various instrument
platforms, including capillary and slab-gel electrophoresis, DNA sequencers,
mass spectrometers, optical plate readers, fluorescence plate readers, micro
array readers and DNA chip systems. We believe the installed base of these
instrument platforms is more than 100,000 instruments in the aggregate. We
believe this strategy will allow us to establish our technologies as the
leading means of SNP scoring more quickly than if our technologies were limited
to a single platform.

 Market Extension

   The pharmaceutical and research communities are currently our largest SNP
scoring markets. Although we expect these markets to grow rapidly over the next
several years, we believe the application of SNP scoring in the clinical and
diagnostic markets, which are still in the early stages of development, has the
most significant long-term potential. We designed our market extension strategy
to leverage our developing research market position, which we expect to
establish using our SNPstream and SNPware product lines, as well as the
services we conduct in our high-throughput MegaSNPatron facility, to enable us
to expand into the clinical markets within the next 12 months. As researchers
find more medically important SNPs using our technologies, products and
services, we believe more suppliers to the clinical and diagnostic markets will
select our SNP scoring technologies. Due to the flexibility and scalability of
our SNP scoring technologies, we also believe we can readily adapt these
technologies to many systems in the clinical and diagnostic markets. As a
result, we believe we are well positioned to collaborate with companies with
large installed bases of clinical systems.

   We have already started to expand our genetic diversity services by
acquiring GeneScreen. GeneScreen sells genetic diversity testing services for
use in forensic and paternity testing as well as for improving the success of
transplantation of bone marrow. As a result of this acquisition, we believe we
are currently the second largest provider of paternity tests in the United
States. We intend to consider other acquisition opportunities to further expand
applications of SNP scoring in industrial and clinical markets.

                                       42
<PAGE>

   We also intend to expand our markets geographically by establishing SNP
scoring facilities and distribution channels in many countries through what we
call our Regional GeneScreen Centers. Through this strategy, we intend to
rapidly penetrate the global market and form relationships with a diverse group
of scientists throughout the world. The Regional GeneScreen Centers are
intended not only to create service revenue but also to serve as applications
laboratories to promote the local sale of our products. We expect to establish
the first of these Regional GeneScreen Centers within the next 12 months.

   As the clinical value of SNPs becomes more accepted, we believe consumers
and their physicians will represent a significant potential market for our
products and services. We plan to develop a Web site based service which we
expect will become operational in the first quarter of 2001. This service would
offer SNP scoring on patient samples. This service would provide a report on
the patients, which patients may share with their doctors, that would indicate
the adverse drug responses to which they may be susceptible or assist in the
selection of drugs which may work best for the patient. We plan to provide a
related service to the healthcare industry which we would design to provide
important topical information about our available services and the field of
pharmacogenetics generally. We plan to provide leadership in establishing high
standards of medical ethics, confidentiality and data security in introducing
and establishing these services. If implemented, we intend to perform this type
of testing at our Regional GeneScreen Centers.

   We also intend to expand into industrial applications of SNP scoring,
including agricultural applications which represent a growing market
opportunity for our products and services. We believe the SNP scoring needs in
the agricultural industry will be similar to those for the pharmaceutical
industry and may involve similar products and/or SNP scoring facilities.
Therefore, we believe we are well-positioned to take advantage of this market
and expect to form collaborations with members of the agricultural industry
community in the last quarter of 2001.

 Proprietary SNP Value Creation

   We have based our proprietary SNP value creation strategy on the creation of
proprietary rights covering the identification of SNPs and their associations
to medically important attributes of patients. We believe the knowledge gained
from such associations will allow healthcare providers to screen patients more
accurately for appropriate medication and treatment. We expect this will result
in proprietary rights covering a broad range of new and existing drugs,
consisting of both "composition of matter" patents which cover the drugs
themselves and "use patents" which extend their label coverage. Because this
approach leverages existing drugs and molecular targets, we expect our drug
development programs will be faster and less expensive than those relying
solely on new chemical entities or new molecular targets.

   We believe we can also use our proprietary SNP value creation strategy to
extend patent coverage on existing drugs as well as drugs that are off patent.
We also believe, in some cases, SNP-enhanced pharmaceuticals will be tantamount
to novel drugs and we may either license these extended patents to
pharmaceutical companies or develop them commercially.

   We believe SNPs will be useful in a variety of research and clinical
applications. As researchers and scientists associate SNPs with medically or
commercially important attributes, we can assemble them into SNP scoring panels
designed for specific applications. Once researchers and scientists find these
SNP associations, we expect to file patents on the use of specific SNPs. For
example, we could package a panel of five SNPs that were all known to correlate
with a lack of response to a certain drug as a SNP scoring kit. Individual
patients might be able to benefit from such a SNP panel by receiving an
effective drug in a shorter period of time. We believe we will generate revenue
from the licensed use of our SNP-IT primer extension technology as well as from
our growing portfolio of proprietary uses of SNPs.

                                       43
<PAGE>

 Sustained Competitive Advantage

   In order to build and sustain our competitive advantage in the field of
genetic diversity, we plan to form strategic alliances and scientific
collaborations and make strategic acquisitions. We believe our financial and
technology positions will make us an attractive partner to a variety of other
participants in this industry. In early 2001, we will seek to expand our
paternity, forensic and transplant genetic testing services in our Regional
GeneScreen Centers to include new testing services marketed to new groups of
customers. We believe we can use our SNP scoring technologies at GeneScreen and
in other Regional GeneScreen Centers to reduce costs or increase the types of
testing offered. Through our collaborations and acquisitions, we will seek
access to distribution channels and opportunities to improve operational
efficiencies. We have already formed a number of collaborations with research
physicians in what we call our Clinical Genetics Network. Through this network,
we believe we will gain access to clinical samples which will enable us to find
correlations between SNPs and medically important attributes. This may create
additional intellectual property rights for us.

   We also intend to continue our aggressive investment in our proprietary
technologies through internal development and by licensing third-party
technologies. Examples of this include the application of our microfluidics
technology to DNA synthesis for use in genomics research and to increase the
throughput and reduce the costs of SNP scoring in our MegaSNPatron facility. We
will also seek to improve the cost-effectiveness of our products and services
through increased automation and development of improved information
technologies.

Products and Services

   We are currently marketing or developing the following products and
services:

Instruments and Systems -- Hardware

   We have developed our instrument systems using an original equipment
manufacturer, or OEM, strategy by modifying instruments already produced by
other companies. We intend to continue this OEM strategy to expand the number
of instruments that we offer while minimizing the engineering expenses normally
associated with the internal development of these systems.

 SNPstream Product Line

   We introduced our SNPstream 25K system in September 1999 and currently have
five systems in operation. This system is based on an OEM robotic system
optimized for use with our proprietary SNP-IT primer-extension SNP scoring
assays, formatted in 384-well plates, and uses our dedicated consumables and
software and provides the user with turn-key SNP scoring capabilities of
approximately 25,000 SNPs per day. The equipment manufacturer installs and
services this system. We support the SNP scoring applications. We intend to
develop a lower-throughput version of our SNPstream system that will enable
users to analyze up to 1,000 SNPs per day. In addition, we intend to introduce
a medium-throughput SNP scoring system capable of scoring between 1,000 and
10,000 SNPs per day. These systems are in development and we expect completion
of beta testing by the end of 2000.

  DNAstream Product Line

   We are designing our DNAstream line of products to enable the simultaneous
synthesis of up to 384 oligonucleotides. Purchasers of DNAstream products may
use these oligonucleotides as the DNA primers for our SNP-IT primer-extension
technology. We are also developing our proprietary Chemtel microfluidic chips
for use in DNA synthesis instruments. We expect the unique control features of
our Chemtel chip will enable our customers to use standard chemistry to produce
DNA of exceptional purity using controlled pore glass or polystyrene supports
in arrays of microreactors. Potential benefits of our DNAstream products
include reduced reagent usage and lower cost enabled by the execution of
reactions in a microreactor well, instead of on the surface of glass plates or
in flow-through cartridges commonly used in current commercial DNA
synthesizers.

                                       44
<PAGE>

We may also use the high-throughput versions of this line of products
internally to produce the DNA required for our high-throughput MegaSNPatron
facility and/or offered on a service basis. We currently expect to launch the
DNAstream product line in 2003.

SNPware Consumables -- Wetware

   Customers may conduct our SNP scoring biochemistry by using a set of
approximately ten reagents. These reagents can be pre-dispensed in the
necessary amounts to run a specific number of SNP scores. We assemble this set
of reagents along with the labware and instructions in a kit for the
convenience of our customers. We intend to sell these kits under our SNPware
brand name for use on our own SNPstream systems as well as the systems of other
companies. We also intend to market our SNPware on one of our Web sites, where
individuals could order custom panels of SNPs to fit their needs. Our SNPware
consumable product line includes the following:

  SNPkits

   SNPkits are the custom 384-plate kits supplied with SNPstream 25K,
containing optimized reagents and software for performing accurate, robust SNP
scoring. We typically format these kits for scoring of specific sets of SNPs at
the request of our customers. A given panel may screen thousands of samples for
a small number of SNPs.

  SNPcode 100, 1000 and custom kits

   We designed the initial version of SNPcode kits for use with the Affymetrix
GeneChip system, which will enable users to run SNP-IT primer extension for SNP
scoring on the Affymetrix GeneChip system. We currently anticipate launching
this line of kits in the third quarter of 2000.

   Additional SNPware Products

   In the future, we anticipate commercializing SNP-IT primer-extension
technology kits for use on other platforms or for other readout methods,
including fluorescence polarization, gel-based sequencers, optical readers and
mass spectroscopy.

   The following chart summarizes the important features of our SNPstream,
DNAstream and SNPware product lines:

Services

   We provide, or intend to provide, a variety of genetic diversity services
through our high-throughput MegaSNPatron facility and Regional GeneScreen
Centers.

 MegaSNPatron Facility Services

   We intend to continue to provide the highest throughput and lowest cost SNP
scoring services available in the industry. We introduced the first phase of
our MegaSNPatron facility in March 1999. We are continuing to expand throughput
capabilities in order to perform over one million SNP scores per day by the
first quarter of 2001.

  .  SNP CONFIRM service. We offer customers SNP confirmation services in
     which we score new SNPs and verify the existence of SNPs discovered
     through DNA sequencing. We currently provide this service to The SNP
     Consortium.

  .  SNP ASSOCIATION service. We offer our SNP association service to
     pharmaceutical companies who design and undertake studies in order to
     discover associations between SNPs and multiple patients' medically
     important attributes. The discovery of these associations is a critical
     phase in the lifecycle of a SNP. Further, we are able to enhance these
     studies with information that we gather from our Clinical Genetics
     Network, whose members have expertise in specific areas of medical
     science.

  .  SNP WIDEMAP service. We are able to perform genome-wide SNP studies at
     the chromosome or genome scale. In order to identify genome regions of
     interest for further mapping studies and candidate gene location a
     researcher or scientist typically uses 300 to 3,000 SNPs. We believe we
     are well positioned with our relationship with The SNP Consortium to
     utilize the SNP sets from its discovery effort in these genome-wide
     mapping studies.

 Regional GeneScreen Center Services

  .  GENESCREEN IDENTITY service. We offer a variety of paternity tests,
     consisting primarily of a standard test involving the mother, child and
     purported father.

  .  GENESCREEN TRANSPLANT TESTING service. We provide screening test
     services for the typing of bone marrow specimens containing human
     leukocyte antigen, or HLA, through both DNA and serological testing.

  .  GENESCREEN FORENSIC service. We test a variety of forensic samples found
     at crime scenes, such as hair, blood, semen, saliva, skin, bone, muscle
     tissue and urine.

  .  INTERNET-BASED service. We plan to provide SNP scoring services via the
     Internet through one of our Web sites within the next 12 months.

Technology

 SNP-IT

   An experiment using SNP-IT primer extension would typically include the
following steps:

  .  Preparation of the target DNA sample.

  .  Capture of the target DNA from a patient sample by hybridization. The
     SNP-IT primer, which includes approximately twenty nucleotide bases
     ending immediately prior to the location of the suspected SNP on the
     patient's sample, is then synthesized. Selective extension of the SNP-IT
     primer with labeled DNA, or primer extension, will only occur when the
     base available at the expected location of the SNP matches the modified
     base available for extension.

  .  Analysis of the SNP-IT primer-extension product. We can analyze the SNP-
     IT primer extension product by a variety of means including
     fluorescence, optical density and mass spectroscopy.

       [Graphic Illustration of the three steps in SNP-IT primer extension]

           Step 1:                 Step 2:              Step 3:
           Prepare                  SNP-IT               Detect

   Since we can perform SNP-IT primer extension in both solution and solid-
phase formats, the operational advantages of our system can be significant. We
can automate the biochemistry using liquid handling robots and can automate the
data acquisition and analysis of test results using readily available array
scanners or Microtiter plate readers that transmit quantitative information to
a computer. We can then automatically interpret this digitized data to provide
custom tailored reports and statistical information on SNP scoring results.

   We facilitate the standardization and reproducibility of SNP-IT primer
extension by the stable attachment or capture and detection of oligonucleotide
primers to the solid phase. This permits large-scale batch preparation of the
SNP-IT arrays, signal uniformity and quality control of the test.

 Microfluidics

   Microfluidics is a set of technologies designed to control the flow,
reactions and measurements of minute amounts of chemicals and biochemicals in
miniaturized systems. Our microfluidics chips are multi-layered devices
consisting of arrayed networks of liquid reagent flow paths in channels or
conduits. These chips allow the processing of sequential and/or parallel
reactions. The reagents conveyed in the conduits and delivered to the location
of the reactions can range in volume from nanoliters to milliliters with a
typical reactor volume being from 100 to 800 nanoliters. We can use a variety
of materials to create our chips, including glass, silicon and polymers. These
structures are typically flat and layered to create the desired three-
dimensional structures with the required network of fluidic channels in the
upper reusable portions and an array of reactors in a consumable lower portion.
We employ a variety of means to create the defined fluidic conduits or reactors
within our chips, which may include laser ablation, etching, photolithography,
milling, molding and embossing.

   Proprietary rights and patents cover our pumping and valving techniques
which control the timing, location and amount of desired reagent delivery
within our chips. Our proprietary valving technology relies on a capillary
break, which halts the reagent flow at a defined expansion point in a fluidic
channel. Electrodes in the channel create simple pneumatic or hydraulic
pressure and electrohydrodynamic pumping. Once the flow is halted, pressure or
electric current can reinitiate the flow.

 Combined Technologies

   We design our microfluidics technologies to drive genetic analysis and drug
discovery to higher throughput while achieving lower costs. By applying our
SNP-IT primer-extension technology to our two-dimensional arrays of identical
reactors and channels, we intend to process in parallel a large number of
similar samples to create highly automated internal facilities capable of
performing millions of SNP scoring experiments per day. Traditional SNP scoring
techniques, including DNA sequencing, cost several dollars per SNP score. We
plan to use our microfluidics technologies to synthesize the DNA for use in our
MegaSNPatron facility. We expect that this will accelerate our ability to
introduce new SNPs and increase the throughput at this facility. By
significantly increasing the throughput of SNP scoring, we intend to
significantly reduce the cost of SNP scoring.

Research and Development

   We intend to continue our aggressive investment in our proprietary
technologies through internal development and licensing of third-party
technologies to increase and improve other characteristics of our systems. We
will also continue to invest in improving the cost-effectiveness of our
products through automation and information technologies. We are actively
pursuing research projects aimed at identifying and developing new technologies
to improve and expand on our genetic diversity, microfluidics and software
products. These projects involve research conducted by us, collaborations with
other researchers and the acquisition of chemistries and other technologies
developed by universities and other academic institutions.

Collaborations and Licenses

   A significant element of our business strategy is to enter into
collaborative research programs and licenses with major pharmaceutical,
biotechnology and agricultural companies which have proven capabilities in
gene-based product discovery and commercialization. We believe this strategy
will allow us to apply our technologies to a broader range of product
development efforts, thereby generating a growing base of intellectual property
rights and revenue for us.

   We have entered into license agreements with Affymetrix and NEN Life Science
Products, Inc. We have also entered into license and collaboration agreements
with SmithKline Beecham and Motorola relating to the microfluidics field,
neither of which is material to our current business. In addition, we have a
license agreement with Sarnoff which is no longer material to our current
business and which we have agreed to terminate upon certain terms described
below.


                                       48
<PAGE>

 Affymetrix, Inc.

   In November 1999, as part of our platform propagation strategy, we entered
into a Collaboration Agreement with Affymetrix, Inc. to develop, manufacture,
market and sell kits capable of performing SNP-IT-based SNP detection on
Affymetrix's GeneChip system and software applications for certain instruments
commercialized by Affymetrix. We agreed to collaborate on the development of
three types of kits, designated under our agreement as Generic Kits, Standard
Kits and Custom Kits. We are responsible for all development costs associated
with the development of Generic Kits and Custom Kits and the optimization of
the SNP-IT primer-extension tests to be used on the Affymetrix GeneChip system.
We will share costs associated with the development of approved Standard Kits.
Affymetrix will market and distribute all Generic and Standard Kits developed
under the agreement, and we will market and distribute all Custom Kits.
Affymetrix has agreed to purchase, and we have agreed to manufacture and
supply, all of Affymetrix's requirements of Generic and Standard kits at
agreed-upon prices. The parties have agreed, through a collaboration committee
to set minimum annual sales requirements for Affymetrix in connection with
sales of its Generic and Standard Kits. The collaboration committee has not yet
set these minimum annual sales requirements and therefore we cannot determine
at this time the materiality or the value of this Agreement to us or to our
business. The collaboration agreement has an initial term of five years and may
be renewed for additional one year terms upon written notice by either party to
the other.

 Sarnoff Corporation

   In December 1997, we entered into a License and Option Agreement with
Sarnoff Corporation pursuant to which Sarnoff granted us rights under certain
technology to research, develop and sell products and services in the field of
combinatorial chemistry and in vitro diagnostics. Sarnoff also granted us
options to acquire exclusive licenses in certain other fields related to
microfluidics, including the fields of genomics, high throughput screening,
research products and cell-based assays. These options extend for a period of
four years and expire one per year over such four year period. In consideration
of the grant of these licenses, in December 1997 we issued to Sarnoff 82,500
shares of our common stock with a fair value of $185,626 and 167,500 shares of
our Series A convertible preferred stock with a fair value of $1,289,750. Upon
the exercise of each option, we are obligated to issue to Sarnoff 33,300 shares
of our common stock and 66,700 shares of our Series A convertible preferred
stock and to fund research to be performed by Sarnoff in an amount of not less
than $5.5 million in the aggregate over a four year period. We exercised one
option in each of December 1998 and December 1999. In consideration for the
options, we issued to Sarnoff 33,300 shares of common stock in each of 1998 and
1999, with a fair value of $114,885 in 1998 and $391,275 in 1999 and 66,700
shares of Series A in each of 1998 and 1999 with a fair value of $400,200 in
1998 and $783,725 in 1999. In addition, we are obligated to issue Sarnoff
50,000 shares of our common stock at the end of each year during the term of
the agreement for each option exercised. Accordingly, we issued 50,000 shares
of common stock with a fair value of $587,500 in 1999 to Sarnoff related to the
option exercised in December 1998. We are also obligated to make royalty
payments on future net sales of products and services developed under these
licenses, if any. The Sarnoff agreement has a term which continues until
terminated by mutual agreement or by Sarnoff if we fail to make any payment due
unless the agreement which is cured within 90 days of notice from Sarnoff.

   As part of our transition from our historical business model based on
microfluidics technologies to our current business model based on our SNP
scoring technologies, on April 13, 2000 we amended our License and Option
Agreement with Sarnoff pursuant to which we mutually agreed to convert our
existing licenses in each relevant field from an ongoing royalty-based license
to a license paid in full. In addition, we exercised and fully paid up our
exclusive option to the genomics and research products fields. We waived our
exclusivity (but retained our non-exclusive licenses) to the fields of high-
throughput screening and cell-based assay fields. Under the terms of this
amendment, we have agreed, in lieu of all our future cash payment, research
funding, potential royalty payment and stock issuance obligations, to make a
one-time payment to Sarnoff in the aggregate amount of approximately
$3.0 million and to issue to Sarnoff 250,000 shares of our common stock and a
warrant to purchase 75,000 shares of our common stock at the price of this
initial public offering or at $12 per share if we have not closed an initial
public offering by April 13, 2001. Upon payment of this consideration, we will
receive exclusive licenses in the fields formerly covered by options under our
License and Option Agreement. Previously on February 2, 2000, we issued 100,000
shares of common stock to Sarnoff as an advance on the issuances which would be
owed in December 2000 for the two option fields previously exercised under the

                                       49
<PAGE>


License and Option Agreement. As this licensed technology has not reached
technological feasibility and has no alternative uses, the cash payment of
approximately $3.0 million and the fair value of the equity securities of
approximately $4.8 million will be charged to research and development expense
in 2000.

 NEN Life Science Products, Inc.

   In February 2000, we entered into an agreement with NEN Life Science
Products, Inc., under which NEN has agreed to supply us with all of our
required terminators for use in our SNPkits. Terminators are nucleotides which
stop the extension of a DNA chain. In consideration of NEN's agreement to
supply us with terminators at preferential prices, we sold to NEN 125,000
shares of our common stock for a purchase price of $750,000 and paid NEN an up-
front fee of $750,000. Under the supply agreement we will pay NEN a royalty fee
based on our revenues for SNPkits we sell. We are also required to purchase
minimum quantities of terminators during each year of the agreement as follows:
first year $333,000; second year $700,000; third year $990,000; and fourth year
$1,320,000. Since the products being supplied are used in our current product
and may be used in future products, we will defer and amortize the $750,000 up
front fee plus the difference between the fair value of the stock issued to NEN
(approximately $1.5 million) over the purchase price for the stock, or a total
of $1.5 million over the estimated four year term of the agreement on a
straight-line basis. Either party can terminate the agreement any time after
four years from the commencement date, without cause, upon 90 days prior
written notice. Either party can also terminate the agreement for cause, such
as a failure to make payments or for any breach that remains uncured following
60 days from the receipt of notice of the breach.

 Other Licenses and Collaborations

   In the past, we have entered into license and collaboration agreements with
respect to our microfluidics technology with Motorola and various other third
parties which are nearing completion and which are not material to our SNP
scoring business. We intend to continue to enter into similar agreements to
enable us to apply our microfluidics technologies for use in our SNP scoring
products and services.

Manufacturing and Suppliers

   We manufacture biochemical kits and microfluidic chips at our Princeton, New
Jersey facility. We believe we currently have sufficient manufacturing capacity
to meet commercial demand for our products through the end of 2000. Although
our manufacturing capacity may be scaled up at our facility, we may need to
acquire additional facilities during the period from 2000 to 2002 and beyond.
We plan to increase our manufacturing capacity by constructing additional
facilities which we believe will be completed within the next 12 months. We may
need to enter into manufacturing arrangements with third parties to produce
commercial quantities of our products.

   Our manufacturing facility is designed to optimize material flow and
personnel movement with centrally located manufacturing and quality control
operations. We produce critical components in an environmentally controlled
clean room which is isolated from the rest of the facility. We are planning to
comply with quality system requirements, or QSRs, analyte specific reagents, or
ASRs, and ISO 9001 registration standards over the next two years. Access and
safety features are designed to meet federal, state and local health
ordinances.

   We rely on outside vendors to manufacture a number of components of our
SNPstream system and some reagents which we provide in our SNPware kits. We
have agreements with Beckman Coulter for the components of our SNPstream system
and NEN Life Science Products, Inc. for some of the key reagents in our

                                       50
<PAGE>

SNPware kits. We also have an agreement with Motorola that relates to the
manufacture and supply of our microfluidics chips. We also currently rely on
DNA provided by suppliers and rely on other third parties to perform DNA
synthesis for us.

   We are establishing a company-wide enterprise resource planning system to
manage and control our material and product inventories. This system will
encompass product costing, materials procurement, production planning and
scheduling, inventory tracking and control and batch records, with links to
document control for all manufacturing, quality control, quality assurance and
regulatory compliance procedures.

   We also perform service testing at all of our facilities. Three of our
facilities have the Clinical Laboratory Improvement Act, or CLIA,
accreditations necessary to be in compliance with the required regulations.

Distribution

   We intend to expand our business internationally by establishing
relationships with distributors in several countries. In larger countries, we
will consider establishing our own direct sales force. Our international
operations would also serve as service locations and redistribution centers for
our consumables.

Intellectual Property

   We have implemented and continue to implement an aggressive patent strategy
designed to provide us with a unique proprietary position in the fields of
pharmacogenetics and microfluidics. This strategy will continue to focus on
protecting and commercializing our current and future products. Our patent
portfolio reflects our international ambitions and includes pursuing patent
protection in many of the industrialized nations of the world. We currently
own, or have exclusive licenses to, 44 United States patents and 6 foreign
patents, and have received notices of allowance for 4 additional U.S. and 1
Australian patent applications. Additionally, we have 175 pending patent
applications of which 70 are United States applications and 105 are foreign
patent applications.

   Our commercial success will also depend, in part on our ability to obtain
patent protection on the SNPs for which we discover utility and on the
products, methods and services for which we base such discoveries. We have
sought and intend to continue to seek patent protection for novel uses of SNPs,
which may have initially been patented by third parties. In such cases, we may
need to license these SNPs from the patent holders to make, use of or sell
products using these SNPs.

   We also rely on both patent and trade secret protection of our intellectual
property. Complex legal and factual determinations and evolving laws make
patent protection uncertain. As a result, we cannot be certain that patents
will be issued from any of our patent applications or from applications
licensed to us or that any issued patents will have sufficient breadth to offer
meaningful protection. In addition, our issued patents or patents licensed to
us may be successfully challenged, invalidated, circumvented or unenforceable
so that our patent rights would not create an effective competitive barrier.
Moreover, the laws of some foreign countries may not protect our proprietary
rights to the same extent as do U.S. and Canadian laws.

   We attempt to protect our trade secrets by entering into confidentiality
agreements with third parties, employees and consultants. Most of our employees
and consultants also sign agreements requiring that they assign to us their
interests in discoveries, inventions, patents and copyrights arising from their
work for us, maintain the confidentiality of our intellectual property, and
refrain from unfair competition with us during their employment and for a
period of time after their employment with us, which includes solicitation of
our employees and customers. We cannot be certain that these agreements will
not be breached or invalidated. In addition, we cannot assure you that third
parties will not independently discover or invent competing technologies or
reverse engineer our trade secrets or other technologies.

                                       51
<PAGE>

   Although we are not a party to any material legal proceedings, in the
future, third parties may file claims asserting that our technologies or
products infringe on their intellectual property. We cannot predict whether
third parties will assert such claims against us or against the licensors of
technologies licensed to us, or whether those claims will harm our business. If
we are forced to defend against such claims, whether they are with or without
any merit or whether they are resolved in favor of or against us or our
licensors, we may face costly litigation and diversion of management's
attention and resources. As a result of such disputes, we may have to develop
costly non-infringing technologies, or enter into licensing agreements. These
agreements, if necessary, may be unavailable on terms acceptable to us, or at
all, which could seriously harm our business and financial condition.

Competition

   The markets for our products are competitive, and we expect the intensity of
competition to increase. Currently, we compete primarily with other companies
that are pursuing technologies and products that are similar to our
technologies and products. Many of our competitors have greater financial,
operational, sales and marketing resources, and more experience in research and
development and commercialization than we have. Moreover, competitors may have
greater name recognition than we do, and may offer discounts as a competitive
tactic. These competitors and other companies may have developed or could in
the future develop new technologies that compete with our products or which
could render our products obsolete. We cannot assure you that we will be able
to make the enhancements to our technologies necessary to compete successfully
with newly emerging techniques.

   In the SNP scoring field, we compete with several companies offering
alternative technology concepts based on indirect detection of the molecule
through hybridization and/or labeling. These companies include: Affymetrix,
Inc., Amersham Pharmacia Biotech Ltd., Genometrix Inc., Luminex Corporation,
Nanogen, Inc., PE Corporation, Rapigene, Inc., Sequenom, Inc., Third Wave
Technologies, Inc. and Visible Genetics, Inc.

   Our principal competitors in the field of pharmacogenetics research and
development include: Celera Genomics Corporation, CLONTECH Laboratories, Inc.,
CuraGen Corporation, Genaissance Pharmaceuticals, Inc., GENSET Corp.,
Millennium Pharmaceuticals, Inc., Myriad Genetics, Inc. and Variagenics, Inc.
Our competitors in the field of DNA testing include: Identagene Corporation,
Laboratory Corporation of America and Lifecodes Corporation, and in the field
of microfluidics include: ACLARA Biosciences Corporation and Caliper
Technologies Corporation.

Government Regulation

   While most of our initial research products will not be subject to
government regulation, we anticipate the manufacturing, labeling, distribution
and marketing of some or all of our future diagnostic products and services
developed or performed using our SNP-related technologies or microfluidics will
be subject to government regulation in the United States and in certain other
countries.

   In the United States, the FDA regulates, as medical devices, most diagnostic
tests and in vitro reagents that companies market as finished test kits or
equipment. Some clinical laboratories, however, purchase individual reagents
intended for specific analyses, and, using those reagents, develop and prepare
their own finished diagnostic tests. The FDA has not generally exercised
regulatory authority over these individual reagents or the finished tests
prepared from them by the clinical laboratories. The FDA has recently proposed
a rule that, if adopted, would regulate reagents sold to clinical laboratories
as medical devices. The proposed rule would also restrict sales of these
reagents to clinical laboratories certified under CLIA as high complexity
laboratories. We intend to market some diagnostic products as finished test
kits or equipment and others as individual reagents. Consequently, some or all
of these products will be regulated as medical devices. The American
Association of Blood Banks, or AABB, has accredited our CLIA laboratories. The
AABB does not permit publicly funded DNA testing services to be offered
together with privately funded testing services in a CLIA laboratory. As a
result, we must maintain the separation of our DNA testing services or risk
losing our accreditation which would adversely affect our business.

                                       52
<PAGE>

   The FDA has also adopted a set of regulations known as Analyte Specific
Reagents, or ASRs, which cover the production of assays and their components
consistent with Good Manufacturing Practices for use in clinical research and
by clinical reference laboratories producing their own assays. We are planning
to satisfy these ASR guidelines within two years in connection with our
manufacture of any SNPstream product that these guidelines may affect.

   The Food, Drug, and Cosmetic Act requires that medical devices introduced to
the United States market, unless exempted by regulation, be the subject of
either a premarket notification clearance, also known as a 510(k) or an
approved premarket approval, or PMA. Some of our products may require a PMA and
others may require a 510(k). With respect to devices reviewed through the
510(k) process, we may not market a device until the FDA issues an order
finding the product to be substantially equivalent to a legally marketed device
known as a "predicate device." A 510(k) submission may involve the presentation
of a substantial volume of data, including clinical data, and may require a
substantial FDA review. The FDA may agree the product is substantially
equivalent to a predicate device and allow the product to be marketed in the
United States. The FDA, however, may (i) determine that the device is not
substantially equivalent and require a PMA, or (ii) require further
information, such as additional test data, including data from clinical
studies, before it is able to make a determination regarding substantial
equivalence. By requesting additional information, the FDA can further delay
market introduction of our products. If the FDA indicates that a PMA is
required for any of our products, the application will require extensive
clinical studies, manufacturing information and likely review by a panel of
experts outside the FDA. The FDA could also require us to conduct clinical
studies to support either a 510(k) submission or a PMA application in
accordance with FDA requirements. Failure to comply with FDA requirements could
result in the FDA's refusal to accept the data or the imposition of regulatory
sanctions. FDA approval of a PMA application could take significantly longer
than a 510(k) approval.

   Medical device laws and regulations are also in effect in many countries in
which we may do business outside the United States. These range from
comprehensive device approval requirements for some or all of our medical
device products to requests for product data or certifications. The number and
scope of these requirements are increasing. Medical laws and regulations are
also in effect in some states in which we do business. We cannot assure you
that we will obtain regulatory approvals in such countries or that we will not
be required to incur significant costs in obtaining or maintaining any such
foreign regulatory approvals. In addition, the export by us of certain of our
products which have not yet been cleared for domestic commercial distribution
may be subject to FDA export restrictions. The failure to obtain product
approvals in a timely fashion or to comply with state or foreign medical device
laws and regulations may have a material adverse impact on our business and
results of operations.

   Our current DNA testing laboratories are regulated under CLIA. The intent of
CLIA is to ensure the quality and reliability of clinical laboratories in the
United States by mandating specific standards in the areas of personnel
qualifications, administration, participation in proficiency testing, patient
test management, quality control, quality assurance and inspections. The
regulations promulgated under CLIA establish three levels of diagnostic tests,
waived, moderately complex and highly complex, and the standards applicable to
a clinical laboratory depend on the level of the tests it performs. Therefore
we cannot assure you that the CLIA regulations and future administrative
interpretations of CLIA will not have a material adverse impact on us by
limiting the potential market for our DNA testing services.

   We are also subject to numerous environmental and safety laws and
regulations, including those governing the use and disposal of hazardous
materials. Any violation of, and the cost of compliance with, these regulations
could have a material adverse effect on our business and results of operations.

                                       53

Employees

   As of March 31, 2000, we employed 220 persons, of whom 38 hold Ph.D. or M.D.
degrees and 13 hold other advanced degrees. Approximately 71 employees are
engaged in research and development, 18 employees are engaged in business
development, sales and marketing, 80 employees are engaged in manufacturing and
DNA testing services and 51 employees are engaged in intellectual property,
finance and other administrative functions. None of our employees is
represented by a collective bargaining agreement, nor have we experienced any
work stoppage. We believe we maintain good relations with our employees.

Facilities

   We lease two facilities which provide us with 40,000 square feet for our
operations in Princeton, New Jersey which serve as our headquarters and as the
base for marketing and product support operations, research and development and
manufacturing activities. We also lease an approximately 19,000 square foot
facility in Dallas, Texas; an approximately 12,500 square foot facility in
Dayton, Ohio; and an approximately 5,100 square foot facility in Sacramento,
California. The latter three facilities include CLIA approved laboratories
where our genetic DNA diversity testing services are located. We currently
believe our facilities are sufficient to meet our space requirements through
the year 2000.

Legal Proceedings


   We are not a party to any material legal proceedings. We are engaged in
discussions with Motorola in an attempt to resolve certain areas of
disagreement that have arisen under our existing collaboration in the area of
microfluidics. The primary issue of disagreement between the parties relates to
whether, under the terms of our agreement, Motorola has a right to obtain a
license to our SNP-IT technology for use with Motorola's microfluidic chips.
While we believe that, under the terms of our agreement, Motorola has no rights
to our SNP-IT technology, we cannot assure you that we can reach agreement with
Motorola on this issue or that we would prevail if this dispute were to develop
into arbitration or litigation. Furthermore, we are likely to incur substantial
costs and expend substantial personnel time in resolving this issue if it
becomes the subject of arbitration or litigation. Nonetheless, we believe that,
even if we fail to successfully resolve this issue or to prevail in any such
arbitration or litigation, we would only be obligated to grant Motorola a non-
exclusive license to use our SNP-IT technology with their microfluidic chips on
terms no less favorable than those offered to other licensees. We do not
believe that this result is likely to have a material adverse affect on our
business or financial condition.

annual meeting of stockholders, a class of directors will be elected for a
three-year term to succeed the directors of the same class whose terms are then
expiring. The terms of the Class I directors, Class II directors and Class III
directors will expire upon the election and qualification of successor
directors at the annual meeting of our stockholders to be held during calendar
years 2001, 2002, and 2003 respectively.

   Each member of our Scientific Advisory and Medical Advisory Boards has
entered into a consulting agreement with us covering the terms of such person's
position as a consultant to us and member of the Scientific Advisory and
Medical Advisory Boards. All scientific or medical advisors own shares and/or
options to acquire shares of our common stock, some of which are subject to
vesting. All of our scientific or medical advisors are employed by employers
other than us and may have commitments to, or consulting or advisory contracts
with, other entities which may conflict or compete with their obligations to
us. Generally, scientific or medical advisors are not expected to devote a
substantial portion of their time to our matters.

Stock Incentive Plans

   We maintain two stock incentive plans for the benefit of our employees,
directors and consultants: our 1995 Stock Incentive Plan and our 2000 Employee,
Director and Consultant Stock Plan.

 1995 Stock Incentive Plan

   Our 1995 Stock Incentive Plan was approved by our Board of Directors and
stockholders in November 1995. The 1995 plan authorizes the issuance of stock
options and restricted stock grants to our employees, directors and
consultants.

   Share Reserve. A total of 3,500,000 shares of our common stock have been
reserved for issuance under the 1995 plan.

   Administration. The compensation committee of our Board of Directors
administers the 1995 plan. The compensation committee has the authority to
determine the following:

  . the persons to whom stock-based awards will be granted;

  . the number of shares to be covered by each stock-based award; and

  . the terms and conditions upon which a stock-based award may be granted.

   Stock-based awards under the 1995 plan will be subject to such terms and
conditions as the compensation committee deems to be appropriate and in our
best interest. These terms may include conditions relating to our right to
reacquire the shares subject to a stock-based award, including the time and
events upon which such rights shall accrue and the purchase price of the
shares.

   Eligibility. Options granted under the 1995 plan may be either (i) options
intended to qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, as amended or (ii) non-qualified stock options.
Incentive stock options may be granted to our employees. The compensation
committee may also grant options at an exercise price less than, equal to or
greater than the fair market value of the common stock on the date of grant.
Under present law, incentive stock options and options intended to qualify as
performance-based compensation under Section 162(m) of the Internal Revenue
Code may not be granted at an exercise price less than the fair market value of
the common stock on the date of grant or less than 110% of the fair market
value in the case of incentive stock options granted to optionees holding more
than 10% of our voting power. The 1995 plan permits the compensation committee
to determine how optionees may pay the exercise price of their options,
including by cash, check or in connection with a "cashless exercise" through a
broker, by surrender of shares of common stock, by delivery of a promissory
note, or by any combination of the permitted forms of payment. Non-qualified
stock options may be granted to our consultants, non-employee directors or
employees.

   General Provisions. The aggregate fair market value, determined on the date
of grant, of shares issuable pursuant to incentive stock options that become
exercisable in any calendar year under the 1995 plan and any of our other
existing or future potential incentive stock plans may not exceed $100,000.
Incentive stock options granted under the 1995 plan may not be granted at a
price less than the fair market value of our common stock on the date of grant,
or 110% of fair market value in the case of employees holding 10% or more of
our voting

                                       62
<PAGE>

stock. Non-qualified stock options granted under the 1995 plan may not be
granted at an exercise price less than the par value per share of our common
stock on the date of the grant. Incentive stock options granted under the 1995
plan expire not more than ten years from the date of grant, or not more than
five years from the date of grant in the case of incentive stock options
granted to an employee or officer holding 10% or more of our voting stock.

   Effect of Employment Termination. An incentive stock option granted under
the 1995 plan may be exercised after the termination of the optionholder's
employment with us, other than by reason of death, disability or termination
for "cause" as defined in the 1995 plan, to the extent exercisable on the date
of termination, at any time prior to the earlier of the option's specified
expiration date or 90 days after such termination. The compensation committee
may specify the termination or cancellation provisions applicable to a non-
qualified stock option. In the event of the optionholder's death or disability,
both incentive stock options and non-qualified stock options generally may be
exercised, to the extent exercisable on the date of death or disability, by the
optionholder or the optionholder's survivors at any time prior to the earlier
of the option's specified expiration date or one year from the date of death or
six months from the date of disability. Generally, in the event of the
optionholder's termination for cause, all outstanding and unexercised options
shall be forfeited.

   Effect of a Change in Control. The 1995 plan provides that in the event of a
"change in control" as defined in the 1995 plan in the beneficial ownership of
us, all options may, at the discretion of the compensation committee, become
fully vested and exercisable immediately prior to the change in control.

 2000 Employee, Director and Consultant Stock Plan.

   Our 2000 Employee, Director and Consultant Stock Plan was approved by our
Board of Directors in February 2000, and by our stockholders in March 2000. The
2000 plan authorizes the issuance of stock options and restricted stock grants
to our employees, directors and consultants.

   Share Reserve. A total of 1,500,000 shares of our common stock have been
reserved for issuance under the 2000 plan.

   Administration. Our Board of Directors has the authority to adopt, amend and
repeal the administrative rules, guidelines and practices relating to the 2000
plan and to interpret its provisions and may delegate authority under the 2000
plan to a committee of the Board of Directors. The compensation committee of
our Board of Directors administers the 2000 plan. The compensation committee
has the authority to determine the following:

  . the persons to whom stock-based awards will be granted;

  . the number of shares to be covered by each stock-based award; and

  .the terms and conditions upon which a stock-based award may be granted.

   Stock-based awards under the 2000 plan will be subject to such terms and
conditions as the compensation committee deems to be appropriate and in our
best interest. These terms may include conditions relating to our right to
reacquire the shares subject to a stock-based award, including the time and
events upon which such rights shall accrue and the purchase price of the
shares.

   Eligibility. Options granted under the 2000 plan may be either (i) options
intended to qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, as amended or (ii) non-qualified stock options.
Incentive stock options may be granted to our employees. The compensation
committee may also grant options at an exercise price less than, equal to or
greater than the fair market value of the common stock on the date of grant.
Under present law, incentive stock options and options intended to qualify as
performance-based compensation under Section 162(m) of the Internal Revenue
Code may not be granted at an exercise price less than the fair market value of
the common stock on the date of grant or less than 110% of the fair market
value in the case of incentive stock options granted to optionees holding more
than 10% of our

                                       63
<PAGE>

voting power. The 2000 plan permits the Board of Directors to determine how
optionees may pay the exercise price of their options, including by cash, check
or in connection with a "cashless exercise" through a broker, by surrender of
shares of common stock, by delivery of a promissory note, or by any combination
of the permitted forms of payment. Non-qualified stock options may be issued to
our consultants, directors or employees.

   General Provisions. The aggregate fair market value, determined on the date
of grant, of shares issuable pursuant to incentive stock options that become
exercisable in any calendar year under the 2000 plan and under any of our other
existing or future potential incentive stock plans may not exceed $100,000.
Incentive stock options granted under the 2000 plan may not be granted at a
price less than the fair market value of our common stock on the date of grant,
or 110% of fair market value in the case of employees holding 10% or more of
our voting stock. Non-qualified stock options granted under the 2000 plan may
not be granted at an exercise price less than the par value per share of our
common stock on the date of the grant. Incentive stock options granted under
the 2000 plan expire not more than ten years from the date of grant, or not
more than five years from the date of grant in the case of incentive stock
options granted to an employee or officer holding 10% or more of our voting
stock. An option granted under the 2000 plan is not transferable by the
optionholder except by will or by the laws of descent and distribution or as
otherwise determined by the compensation committee and set forth in the
applicable option agreement.

   Effect of Termination of Employment.  An incentive stock option granted
under the 2000 plan may be exercised after the termination of the
optionholder's employment with us, other than by reason of death, disability or
termination for "cause" as defined in the 2000 plan, to the extent exercisable
on the date of termination, at any time prior to the earlier of the option's
specified expiration date or 90 days after such termination. The compensation
committee may specify the termination or cancellation provisions applicable to
a non-qualified stock option. In the event of the optionholder's death or
disability, both incentive stock options and non-qualified stock options
generally may be exercised, to the extent exercisable on the date of death or
disability, by the optionholder or the optionholder's survivors at any time
prior to the earlier of the option's specified expiration date or one year from
the date of death or disability. Generally, in the event of the optionholder's
termination for cause, all outstanding and unexercised options shall be
forfeited.

   Effect of Acquisition. If we are to be consolidated with or acquired by
another entity in a merger, sale of all or substantially all of our assets or
otherwise, the compensation committee or the board of directors of any entity
assuming our obligations under the 2000 plan shall, as to outstanding options
under the 2000 plan, either (i) make appropriate provision for the continuation
of such options by substituting, on an equitable basis, for the shares then
subject to such options, the consideration payable with respect to the
outstanding shares of common stock in connection with such an acquisition or
securities of the successor or acquiring entity; or (ii) upon written notice to
the optionholders, provide that all options must be exercised (either to the
extent then exercisable or, at the discretion of the compensation committee,
all options being made fully exercisable for purposes of the transaction)
within a specified number of days of the date of such notice, at the end of
which period the options shall terminate; or (iii) terminate all options in
exchange for a cash payment equal to the excess of the fair market value of the
shares subject to each such option (either to the extent then exercisable or,
at the discretion of the compensation committee, all options being made fully
exercisable for purposes of the transaction) over the exercise price thereof.

Director Compensation

   All of the directors are reimbursed for expenses incurred to attend meetings
of our Board of Directors and any committees of the Board of Directors. We have
in the past granted non-employee directors options to purchase our common stock
pursuant to the terms of our 1995 Incentive Stock Plan and our Board of
Directors continues to have the discretion to grant options to new non-employee
directors. All non-employee directors have received stock options.

                       Option Grants in Last Fiscal Year

   The following table sets forth information regarding options granted by us
to our named executive officers during the fiscal year ended December 31, 1999.
We have never granted any stock appreciation rights. The potential realizable
value is calculated based on the term of the option at its time of grant. It is
calculated assuming that the fair market value of common stock on the date of
grant appreciates at the indicated annual rate compounded annually for the
entire term of the option and that the option is exercised and sold on the last
day of its term for the appreciated stock price. These numbers are calculated
based on the requirements of the Securities and Exchange Commission and do not
reflect our estimate of future stock price growth. Actual gains, if any, on
stock option exercises are dependent on the future performance of the common
stock and overall stock market conditions. The amounts reflected in the table
may not necessarily be achieved. The percentage of total options granted to
employees in the last fiscal year is based on options to purchase an aggregate
of     shares of common stock granted under our option plans. There was no
public market for our common stock as of December 31, 1999. Accordingly, the
fair market value on December 31, 1999 is based on an assumed initial public
offering price of $12.00 per share.

 Corporate 401(k) Plan

   We sponsor a 401(k) plan covering employees who meet certain defined
requirements. Under the terms of our 401(k) plan, participants may elect to
make contributions on a pre-tax and after-tax basis, subject to certain
limitations under the Internal Revenue Code and we may match a percentage of
employee contributions, on a discretionary basis, as determined by our Board of
Directors. We may make other discretionary contributions to the 401(k) plan,
although pursuant to a determination by our Board, we currently match 50% of
the first 4% of employee contributions.

 Executive Deferred Compensation Plan

   We have established an executive deferred compensation plan, which took
effect on February 3, 1999. It was established primarily for the purpose of
providing life and disability insurance and retirement benefits as well as
deferred compensation for our executive officers, directors and highly
compensated employees. Participants in the plan are permitted to defer receipt
of, and income taxation on, up to 50% of their regular

                                       66

base salary and all or any portion of any bonus until they terminate their
employment with us. Under the terms of the plan, we will also provide an annual
cash allowance to each eligible participant to pay the premiums for their
supplemental life and disability insurance.

 GeneScreen 401(k) Plan

   We sponsor a 401(k) plan covering our GeneScreen employees who meet certain
defined requirements. Under the terms of the GeneScreen 401(k) plan,
participants may elect to make contributions on a pre-tax basis, up to 15% of
compensation, subject to certain limitations under the Internal Revenue Code.
We may at our discretion match employee contributions at a discretionary rate
and make discretionary profit sharing contributions to the 401(k) Plan.

Employment Agreements

   We entered into a three year employment agreement with Dale R. Pfost, Ph.D.,
effective as of January 2000, to serve as our President and Chief Executive
Officer at an annual base salary of $350,000. Under the terms of his employment
agreement, Dr. Pfost is entitled to receive an annual bonus of up to 25% of his
base salary to be awarded based upon our achievement of specific performance
milestones. If our Board determines in good faith that our performance has
exceeded such milestones, it may increase Dr. Pfost's bonus to up to 35% of his
base salary. We also contribute an additional amount equal to 10% of
Dr. Pfost's annual salary to a non-qualified retirement plan for the sole
benefit of Dr. Pfost. In addition, upon execution of the agreement, we issued
to Dr. Pfost options to purchase an aggregate of 730,000 shares of our common
stock. Of these 730,000 options, options to purchase 100,000 shares were
previously granted in December 1999 with an exercise price of $1.25 per share.
The remaining 630,000 options have an exercise price of $6.00 per share. A
total of 360,000 of these newly issued options with $6.00 per share exercise
prices will vest if and when the price of our stock exceeds certain specified
levels for 45 consecutive trading days. We may terminate the agreement with or
without cause at any time. If we terminate Dr. Pfost's employment for cause, we
are only obligated to pay him severance equal to his accrued base salary up to
the date of termination. If we terminate Dr. Pfost's employment without cause,
or if Dr. Pfost terminates his employment for good reason, we are obligated to
pay Dr. Pfost a severance amount equal to his annual base salary and benefits
for an eighteen month period following the effective date of termination. We
must provide Dr. Pfost with notice of termination in advance of the effective
termination date. The advance notice period ranges from six to eighteen months,
depending on the timing of the effective date of the termination.

   We entered into a three year employment agreement with Donald R. Marvin,
effective as of January 2000, to serve as our Senior Vice President, Corporate
Development and Chief Operating Officer at an annual base salary of $275,000.
Under the terms of his employment agreement, Mr. Marvin is entitled to receive
an annual bonus of up to 25% of his base salary to be awarded based upon our
achievement of specific performance milestones. If our Board determines in good
faith that our performance has exceeded such milestones, it may increase
Mr. Marvin's bonus to up to 35% of his base salary. In addition, upon execution
of the agreement, we issued to Mr. Marvin options to purchase an aggregate of
557,000 shares of our common stock. Of these 557,000 options, options to
purchase 67,000 shares were previously granted in December 1999 with an
exercise price of $1.25 per share. The remaining 490,000 options have an
exercise price of $6.00 per share. A total of 240,000 of these newly issued
options with $6.00 per share exercise prices will vest if and when the price of
our stock exceeds certain specified levels for 45 consecutive trading days. We
also contribute an additional amount equal to 5% of Mr. Marvin's annual salary
to a non-qualified retirement plan for the sole benefit of Mr. Marvin. We may
terminate the agreement with or without cause at any time. If we terminate Mr.
Marvin's employment for cause, we are only obligated to pay him severance equal
to his accrued base salary up to the date of termination. If we terminate Mr.
Marvin's employment without cause, or if Mr. Marvin terminates his employment
for good reason, we are obligated to pay Mr. Marvin a severance amount equal to
his annual base salary and benefits for an eighteen month period following the
effective date of termination. We must provide Mr. Marvin with notice of
termination in advance of the effective termination date. The advance notice
period ranges from six to eighteen months, depending on the timing of the
effective date of the termination.

                     TRANSACTIONS WITH EXECUTIVE OFFICERS,
                    DIRECTORS AND FIVE PERCENT STOCKHOLDERS

   Since January 1999, there has not been nor is there currently proposed, any
transaction or series of similar transactions to which were or are to be a
party in which the amount involved exceeded or exceeds $60,000 and in which any
director, executive officer, holder of more than 5% of our common stock or any
member of the immediate family of any of the foregoing persons had or will have
a direct or indirect material interest other than the transactions described
below.

   In December 1997, we entered into a License and Option Agreement with
Sarnoff Corporation, a five percent beneficial stockholder, pursuant to which
we received a license under certain technology to research, develop and sell
products and services in the field of combinatorial chemistry and in vitro
diagnostics and options to obtain exclusive licenses for the use of technology
in four designated areas of microfluidics. In consideration of the grant of the
license, we issued Sarnoff 82,500 shares of our common stock and 167,500 shares
of our Series A convertible preferred stock. Concurrent with the exercise of
each option, we are obligated to issue Sarnoff 33,300 shares of our common
stock and 66,700 shares of our Series A convertible preferred stock and to fund
research to be performed by Sarnoff at an amount defined in the agreement, but
no less than $5.5 million in the aggregate. We exercised one option in each of
December 1998 and 1999. In consideration of the exercise of each option, we
issued Sarnoff 33,300 shares of our common stock and 66,700 shares of our
Series A convertible preferred stock in 1998 and in 1999. We are also obligated
to issue Sarnoff an additional 50,000 shares of common stock at the end of each
year during the term of the agreement for each option exercised. We issued
Sarnoff 50,000 shares of common stock in 1999 in connection with the option we
exercised in December 1998. Since the technology licensed to us under the
License and Option Agreement with Sarnoff relates to, and was developed under
funding provided in part by, and involves certain rights of, SmithKline Beecham
Corporation, we also agreed, as a condition to the execution of the agreement,
to issue SmithKline Beecham additional shares of our common stock as options
are exercised by us. Consequently, in connection with the exercise of the two
options, we issued SmithKline Beecham 10,000 shares of our common stock on
February 2, 2000, 5,000 of which shares should have been issued as of December
31, 1998 and as of December 31, 1999, respectively.

   In June 1999, we completed a bridge financing in which we issued
subordinated convertible term notes in the aggregate principal amount of
$7,590,000 and warrants to purchase an aggregate of 381,500 shares of common
stock. In connection with this offering, we issued OrbiMed Advisors, LLC, a
five percent beneficial stockholder, through each of Eaton Vance Worldwide
Health Sciences Fund, Finsbury Worldwide Pharmaceutical Trust and
PHARMAw/HEALTH, notes in the aggregate principal amount of $2,750,000 and
warrants to purchase an aggregate of 137,500 shares of our common stock. We
also issued INVESCO Global Health Sciences Fund, a five percent beneficial
stockholder, through its affiliate Pirate Ship & Co., a note in the aggregate
principal amount of $1,800,000 and warrants to purchase 90,000 shares of our
common stock. On December 22, 1999, in accordance with the terms of the bridge
financing, we issued OrbiMed Advisors and INVESCO Global Health Sciences Fund,
additional warrants to purchase an additional 137,500 and 89,910 shares of
stock, respectively.

   In November 1999, we completed a bridge financing in which we issued a
subordinated convertible term note in the aggregate principal amount of
$2,250,000 to Affymetrix, Inc., a five percent beneficial owner of the Series E
mandatorily redeemable convertible preferred stock. In November 1999, we also
entered into a collaboration agreement with Affymetrix to develop, manufacture,
market and sell SNP-IT based SNP detection kits on Affymetrix GeneChip systems.
See "Business--Collaborations and Licenses" for a description of this
agreement.

   In December 1999 and January 2000, we completed a private placement in which
we issued 18,882,691 shares of Series E convertible preferred stock, which
amount includes the shares issued in connection with the acquisition of
GeneScreen. INVESCO Global Health Sciences Fund, a five percent beneficial
stockholder, through each of Global Health Sciences Fund and Pirate Ship & Co.,
purchased an aggregate of 645,189 shares of Series E convertible preferred
stock in this offering for an aggregate purchase price of $2,903,350 consisting
of cash in the aggregate principal amount of $1,000,000, and the conversion of
the principal amount of and accrued interest on a bridge note held by Pirate
Ship & Co. in the aggregate amount of $1,903,350. OrbiMed

                                       68

Advisors, LLC, a five percent beneficial stockholder, through each of Caduceus
Capital II, L.P., Eaton Vance Worldwide Health Sciences Fund, Finsbury
Worldwide Pharmaceutical Trust, PHARMAw/HEALTH and Winchester Global Trust
Company Limited, as Trustee for Caduceus Capital Trust, purchased an aggregate
of 1,312,864 shares of Series E convertible preferred stock for an aggregate
purchase price of $5,907,888 in this offering consisting of cash in the
aggregate amount of $3,000,000, and the conversion of the principal of and all
accrued interest on the three bridge notes held by each of Eaton Vance
Worldwide Health Sciences Fund, Finsbury Worldwide Pharmaceutical Trust and
PHARMA w/HEALTH in the aggregate amount of $2,907,860. Oracle Strategic

an aggregate purchase price of $9,675,000. Affymetrix, Inc., a five percent
beneficial owner of the Series E convertible preferred stock, purchased an

interest on a bridge note held by Affymetrix in the aggregate amount of
$2,276,888. Deutsche Vermogensbildungsgesellschaft mbH (DVG), a five percent

shares of the Series E convertible preferred stock in this offering for an
aggregate purchase price of $4,500,000. The holders of Series E convertible
preferred stock were also granted certain registration rights. See "Description

                             PRINCIPAL STOCKHOLDERS

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

  . each person known by us to beneficially own more than 5% of our common
    stock;

  . each of our directors;

  . each of our executive officers named in the summary compensation table;
    and

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

   Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock under options held by that person that are currently
exercisable or exercisable within 60 days of March 31, 1999 are considered
outstanding. These shares, however, are not considered outstanding when
computing the percentage ownership of each other person.

   Except as indicated in the footnotes to this table and pursuant to state
community property laws, each stockholder named in the table has sole voting
and investment power for the shares shown as beneficially owned by them.
Percentage of ownership is based on 25,989,381 shares of common stock
outstanding on March 31, 2000 and 33,989,381 shares of common stock outstanding
after completion of this offering based on the number of shares outstanding on
March 31, 2000. This table assumes no exercise of the underwriters' over-
allotment option. Unless otherwise indicated in the footnotes, the address of
each of the individuals named below is: c/o Orchid BioSciences, Inc., 303

                          DESCRIPTION OF CAPITAL STOCK

   After this offering, our authorized capital stock will consist of 50,000,000
shares of common stock, $.001 par value per share, and 5,000,000 shares of
preferred stock, $.001 par value per share.

   After the closing of this offering, based on the number of shares
outstanding on March 31, 2000 there will be:

  . 33,989,381 shares of common stock outstanding;

  . 3,250,995 options to purchase shares of common stock outstanding of which
    331,802 are exercisable as of March 31, 2000;

  . 1,237,138 warrants to purchase shares of common stock outstanding,
    1,085,138 of which are exercisable as of March 31, 2000; and

  . no shares of preferred stock outstanding.

Common Stock

   Holders of our common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders and do not have
cumulative voting rights. Accordingly, holders of a majority of the shares of
common stock entitled to vote in any election of directors may elect all of the
directors standing for election. Holders of common stock are entitled to
receive proportionately any such dividends declared by the board of directors,
out of legally available funds for the dividends subject to the rights of the
holders of our preferred stock and any preferences that may be applicable to
any other then outstanding preferred stock. Upon our liquidation, dissolution
or winding up, the holders of our common stock are entitled to receive ratably
with the holders of our Series C Convertible Preferred Stock and Series E
Convertible Preferred Stock our net assets available after the payment of all
debts and other liabilities and subject to the liquidation preferences of any
outstanding preferred stock. Holders of common stock have no preemptive,
subscription, redemption or conversion rights and are not subject to future
calls or assessments by us. No sinking fund provisions apply to our common
stock. The outstanding shares of common stock are, and the shares offered by us
in this offering will be, when issued and paid for, fully paid and
nonassessable. The rights, preferences and privileges of holders of our common
stock are subject to the rights of the holders of shares of any series of
preferred stock which we may designate and issue in the future. Some holders of
common stock have the right to require us to register their shares of common
stock under the Securities Act in specified circumstances. See "Shares Eligible
for Future Sale."

Preferred Stock

   Upon the closing of this offering, all of our outstanding shares of Series A
convertible preferred stock, Series B convertible preferred stock, Series C
mandatorily redeemable convertible preferred stock and Series E mandatorily
redeemable convertible preferred stock will be converted into 24,781,562 shares
of common stock.

   Under the terms of our certificate of incorporation, our Board of Directors
will be authorized to issue up to 5,000,000 shares of preferred stock in one or
more series without stockholder approval. Our Board of Directors also has
discretion to determine the rights, preferences, privileges and restrictions,
including voting rights, dividend rights, conversion rights, redemption
privileges and liquidation preferences of each series of preferred stock.

   The purpose of authorizing our Board of Directors to issue preferred stock
in one or more series and determine the number of shares in the series and its
rights and preferences is to eliminate delays associated with a stockholder
vote on specific issuances. Examples of rights and preferences that the Board
of Directors may fix are (1) dividend rights, (2) dividend rates, (3)
conversion rights, (4) voting rights, (5) terms of redemption, including
sinking price or prices, and (6) liquidation preferences. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes,

                                       72
<PAGE>

could make it more difficult for a third party to acquire, or could discourage
a third party from acquiring, a majority of our outstanding voting stock. The
rights of holders of our common stock described above will be subject to, and
may be adversely affected by, the rights of any preferred stock that we may
designated and issue in the future.

Warrants

   As of March 31, 2000, there were outstanding warrants to purchase 1,237,138
shares of common stock held by 16 investors. Such warrants have expiration
dates ranging from June 2002 to June 2004, and have a weighted average exercise
price of $4.64 per share. The number of shares for which the warrants are
exercisable is subject to adjustment for stock splits, combinations or
dividends and reclassifications, exchanges or substitutions.

Registration Rights

   After this offering, the holders of approximately 24,906,562 shares of
common stock will be entitled to rights with respect to the registration of
those shares under the Securities Act of 1933 as follows:

   Demand Rights. Under the terms of the agreements between us and the holders
of those registrable shares, the former holder of Series A convertible
preferred stock, the former holder of Series B convertible preferred stock and
the holders of not less than one-third of the former holders of Series C
convertible preferred stock and Series E convertible preferred stock may at any
time require us to file a registration statement under the Securities Act with
respect to shares of common stock owned by them and we are required to use our
reasonable best efforts to effect that registration. This right will accrue to
the former holder of Series A convertible preferred stock and the former holder
of Series B convertible preferred stock at any time after the closing of this
offering and to the former holders of Series C convertible preferred stock and
Series E convertible preferred stock at any time after the first anniversary of
the closing of this offering.

   Registration Rights. Also, if we propose to register any of our securities
under the Securities Act, other than in connection with demand registrations,
registrations on Form S-8 or in connection with our initial public offering,
the foregoing holders are entitled to notice of and to include in the
registration shares of common stock owned by them. This right will accrue to
the former holder of Series A convertible preferred stock and the former holder
of Series B convertible preferred stock at any time after the closing of this
offering and to the former holders of Series C convertible preferred stock and
Series E convertible preferred stock at any time after the first anniversary of
the closing of this offering.

   S-3 Registration Rights. Finally, the former holders of not less than 25% of
the Series C convertible preferred stock and Series E convertible preferred
stock and a certain holder of common stock may after the completion of this
offering require us to file a registration statement under the Securities Act
on Form S-3 with respect to shares of common stock owned by them. This right
will accrue to the holders of Series C convertible preferred stock and Series E
convertible preferred stock at any time after the completion of this offering
and to the holder of common stock at any time after the first anniversary of
the completion of this offering.

   All of these registration rights are subject to various conditions and
limitations, among them certain rights of the underwriters of an offering to
limit the number of shares included in a registration and our right not to
effect a requested registration within 90 days after the effective date of a
previous registration on a Form S-1 or within 90 days after the effective date
of a registration which included all shares requested by holders of registrable
shares. We will bear all of the expenses incurred in connection with all
exercises of these registration rights.

Delaware Law and Certain Charter and By-law Provisions

   We are subject to the provisions of Section 203 of the Delaware General
Corporation Law statute. Section 203 prohibits a publicly held Delaware
corporation from engaging in a business combination with an interested
stockholder for a period of three years after the person becomes an interested
stockholder, unless the business combination is approved in a prescribed
manner. A business combination includes mergers, asset sales

                                       73
<PAGE>

and other transactions resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an interested stockholder is a
person who, together with affiliates and associates, owns, or within three
years did own, 15% or more of the corporation's voting stock.

   Our by-laws divide the Board of Directors into three classes with staggered
three-year terms. See "Management." Under the by-laws, any vacancy on our Board
of Directors, including a vacancy resulting from an enlargement of our Board of
Directors, may only be filled by vote of a majority of the directors then in
office. The classification of the Board of Directors and the limitation on
filling of vacancies could make it more difficult for a third party to acquire,
or discourage a third party from acquiring, control of our company.

   Our by-laws also provide that after this offering, stockholders can only
take action at an annual meeting or special meeting, and not by written action
in lieu of a meeting. Our by-laws further provide that only stockholders
holding a majority of outstanding shares, our Chairman of the Board, President
or our Board of Directors may call a special meeting of stockholders.

   Our stockholders must comply with advance notice and information disclosure
requirements in order for any matter to be considered "properly brought" before
a meeting. Stockholders must deliver written notice to us between 60 and 90
days prior to the meeting. If we give less than 70 days' notice or prior public
disclosure of the meeting date, stockholders must deliver written notice to us
within ten days following the date upon which the notice of the meeting was
mailed or such public disclosure was made, whichever occurs first. If the
matter relates to the election of directors, the notice must set forth specific
information regarding each nominee and the nominating stockholder. For any
other matter, the notice must set forth a brief description of the proposed
matter and certain information regarding the proponent stockholder. These
provisions could delay until the next stockholders' meeting proposed actions
which are favored by the holders of a majority of our outstanding voting
securities. These provisions could also discourage a third party from making a
tender offer for our common stock, because even if it acquired a majority of
the outstanding voting securities, the third party would be able to take action
as a stockholder only at a duly called stockholders' meeting, and not by
written consent.

   The Delaware General Corporation Law statute provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or by-laws,
unless a corporation's certificate of incorporation or by-laws, as the case may
be, requires a greater percentage. Our by-laws require the affirmative vote of
holders of at least 70% of the votes which all the stockholders would be
entitled to cast in any annual election of directors or class of directors to
amend or repeal any of the provisions described in the prior two paragraphs.

   Our certificate of incorporation contains certain provisions permitted under
the Delaware General Corporation Law statute relating to the limitation of
liability of directors. These provisions eliminate a director's liability for
monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. Further, the certificate of incorporation contains
provisions to indemnify our directors and officers to the fullest extent
permitted by the Delaware General Corporation Law statute. We believe these
provisions will assist us in attracting and retaining qualified individuals to
serve as our directors.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Before this offering, there has been no public market for our securities.
After completion of this offering and assuming no exercise of the underwriter's
over-allotment option, there will be 33,989,381 shares of common stock
outstanding based upon the number of shares outstanding as of March 31, 1999.
Of these shares, the 8,000,000 shares sold in this offering will be freely
tradable without restriction or further registration under the Securities Act
of 1933, except that any shares purchased by our "affiliates," as that term is
defined in Rule 144 under the Securities Act, may generally only be sold in
compliance with the limitations of Rule 144 described below.

Sales of Restricted Shares

   All of the shares offered under this prospectus will be freely tradable in
the open market. The remaining 25,989,381 shares of common stock that will be
outstanding after this offering will be considered "restricted securities"
under Rule 144 of the Securities Act. Generally, restricted securities that
have been owned for a period of at least two years may be sold immediately
after the completion of this offering, and restricted securities that have been
owned for at least one year may be sold 90 days after the completion of this
offering. Certain of the restricted securities are subject to lock-up
agreements with the underwriters. Persons subject to lock-up agreements have
agreed not to sell shares of our common stock without the prior permission of
Credit Suisse First Boston Corporation for a period of 180 days after the
completion of this offering. Credit Suisse First Boston Corporation has
indicated that it does not intend to release anyone from the lock-up agreement.
The table below sets forth information regarding potential sales of restricted
securities.

  . 910,754 shares may be sold immediately after completion of this offering;
    and

  . 6,474,484 additional shares may be sold upon the expiration of the lock-
    up agreements.

Options

   Shares of common stock may also be issued and sold upon the exercise of
options. After this offering, we intend to register substantially all of the
common stock, which may be issued under our 1995 Stock Incentive Plan and our
2000 Employee, Director and Consultant Stock Plan and other stock options not
issued under a plan. Shares issued upon the exercise of stock options after the
effective date of the registration statements on Form S-8 will be eligible for
resale in the public market without restriction, subject to Rule 144
limitations applicable to affiliates and the lock-up agreements noted above, if
applicable.

Registration Rights

   Upon completion of this offering, the holders of 24,906,562 shares of common
stock will be entitled to various rights with respect to the registration of
these shares under the Securities Act. Registration of these shares under the
Securities Act would result in these shares becoming freely tradable without
restriction under the Securities Act immediately upon the effectiveness of the
registration, except for shares purchased by affiliates. See "Description of
Capital Stock--Registration Rights" for a more complete description of these
registration rights.

Effect of Sales of Shares

   Prior to this offering, there has been no public market for our common
stock, and we cannot advise you as to the effect, if any, that sales in the
public market of shares of our common stock, or the availability of shares for
sale, will have on the market price of our common stock prevailing from time to
time. Nevertheless, sales of significant numbers of shares of our common stock
in the public market could adversely affect the market price of our common
stock and could impair our ability to raise capital.

</TABLE>

   The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering of common stock may be terminated.

   We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 1,200,000 additional shares of our common stock from us at
the initial public offering price less the underwriting discounts and
commissions. The option may be exercised only to cover any over-allotments of
the common stock.

   The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $     per share. The
underwriters and selling group members may allow a discount of $     per share
on sales to other broker/dealers. After the initial public offering, the
public offering price and concession and discount to broker/dealers may be
changed by the representatives.

   The following table summarizes the compensation and estimated expenses we
will pay.

   The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the common stock being offered.

   We, our directors and officers and the majority of our stockholders agreed
that we will not and they will not:

  . offer, sell, contract to sell, announce our intention to sell, pledge or
    otherwise dispose of, directly or indirectly; or

  . file with the Securities and Exchange Commission a registration statement
    under the Securities Act relating to;

                                      76
<PAGE>

any additional shares of our common stock or securities convertible into or
exchangeable or exercisable for any of our common stock, without the prior
written consent of Credit Suisse First Boston Corporation for a period of 180
days after the date of this prospectus, except in connection with our incentive
stock plan. In addition, we may issue shares of our common stock in connection
with any acquisition of another company if the terms of such issuance provide
that such common stock shall not be resold prior to the expiration of the 180
day period referenced above.

   The underwriters have reserved for sale, at the initial public offering
price, up to 400,000 shares of the common stock for our employees, directors
and certain other persons associated with us who may wish to purchase common
stock in the offering. The number of shares available for sale to the general
public in the offering will be reduced to the extent these persons purchase
these reserved shares. Any reserved shares not so purchased will be offered by
the underwriters to the general public on the same terms as the other shares.

   We have agreed to indemnify the underwriters against liabilities under the
Securities Act of 1933, or to contribute to payments which the underwriters may
be required to make as a result of these liabilities.

   We have applied to list our common stock on The Nasdaq Stock Market's
National Market under the symbol "ORCH."

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price will be determined by negotiation
between us and the underwriters. The principal factors to be considered in
determining the public offering price will be:

  . the information presented in this prospectus and otherwise available to
    the underwriters;

  . the history and the prospects for the industry in which we will compete;

  . the ability of our management;

  . our prospects for our future earnings;

  . the present state of our development and our current financial condition;

  . the general condition of the securities markets at the time of this
    offering; and

  . the recent market prices of, and the demand for, publicly traded common
    stock of generally comparable companies.

   The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Securities Exchange Act of 1934.

  . Over-allotment involves syndicate sales in excess of the offering size,
    which creates a syndicate short position.

  . Stabilizing transactions permit bids to purchase the underlying security
    so long as the stabilizing bids do not exceed a specified maximum.

  . Syndicate covering transactions involve purchases of the common stock in
    the open market after the distribution has been completed in order to
    cover syndicate short positions.

  . Penalty bids permit the representatives to reclaim a selling concession
    from a syndicate member when the shares of common stock originally sold
    by such syndicate member are purchased in a stabilizing transaction or a
    syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of these transactions. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

   The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common
stock in Canada must be made in accordance with applicable securities laws
which will vary depending on the relevant jurisdiction, and which may require
resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the common stock.

Representations of Purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that (1) such purchaser is entitled under
applicable provincial securities laws to purchase such common stock without the
benefit of a prospectus qualified under such securities laws, (2) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (3) such purchaser has reviewed the text above under "Resale
Restrictions."

Rights of Action (Ontario Purchasers)

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or recission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

Enforcement of Legal Rights

   All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or persons outside of Canada.

Notice to British Columbia Residents

   A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. This report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one report must
be filed in respect of common stock acquired on the same date and under the
same prospectus exemption.

Taxation and Eligibility for Investment

   Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                          INDEPENDENT AUDITORS' REPORT

The Stockholders and Board of Directors
Orchid BioSciences, Inc.:

   We have audited the accompanying consolidated balance sheets of Orchid
BioSciences, Inc. and subsidiaries as of December 31, 1998 and 1999, and the
related consolidated statements of operations, stockholders' deficit and cash
flows for each of the years in the three-year period ended December 31, 1999.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Orchid
BioSciences, Inc. and subsidiaries as of December 31, 1998 and 1999, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1999, in conformity with generally
accepted accounting principles.

                           December 31, 1998 and 1999

(1) Summary of Significant Accounting Policies

 Organization and Business Activities

   Orchid BioSciences, Inc. (previously known as Orchid Biocomputer, Inc.) and
subsidiaries (the "Company"), was organized under the laws of the State of
Delaware on March 8, 1995 to develop and commercialize genetic diversity
technologies, products and services using the Company's proprietary
biochemistry for scoring single nucleotide polymorphisms ("SNPs") and
microfluidics technologies for applications in drug discovery, principally in
the field of pharmacogenetics and DNA synthesis. The Company was a wholly-owned
subsidiary of Sarnoff Corporation ("Sarnoff") at inception, was reduced to a
majority-owned subsidiary of Sarnoff in 1995 and as a result of the December
1997 financing, Sarnoff's ownership in the Company was reduced to less than a
majority (see notes 11 and 13).

   On December 30, 1999, the Company acquired GeneScreen, Inc. ("GeneScreen"),
a wholly-owned subsidiary of the Company, which operates genetic diversity
testing laboratories in Dallas, Texas; Dayton, Ohio, and Sacramento,
California. GeneScreen performs DNA laboratory analyses for paternity,
transplantation and forensic testing. GeneScreen's primary sources of revenue
represent paternity testing under contracts with several state and county
government agencies and transplantation testing under grants from the National
Marrow Donor Program.

   The Company has not yet achieved profitable operations or positive cash flow
from operations. There is no assurance that profitable operations, if ever
achieved, could be sustained on a continuing basis. In addition, development
and commercialization activities will require significant additional financing.
The Company's accumulated deficit aggregated $50,757,971 through December 31,
1999 and it expects to incur substantial losses in future periods.

 Consolidated Financial Statements

   The accompanying consolidated financial statements include the results of
operations of the Company and its wholly-owned subsidiaries. All intercompany
accounts and transactions have been eliminated in consolidation. As a result of
the acquisition of GeneScreen, Inc. ("GeneScreen") during 1999, the Company is
no longer considered to be in the development stage for financial reporting
purposes as it was in the prior years.

 Cash and Cash Equivalents

   The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents. All
cash and cash equivalents are held in United States financial institutions and
money market funds. To date, the Company has not experienced any losses on its
cash and cash equivalents. The carrying amount of cash and cash equivalents
approximates its fair value due to its short-term and liquid nature.

 Short-term Investments

   Short-term investments consist of corporate debt securities with original
maturities greater than three months. In accordance with Statement of Financial
Accounting Standards No. 115 ("SFAS 115"), "Accounting for Certain Investments
in Debt and Equity Securities," the Company classifies its short-term
investments as available for sale. Available for sale securities are recorded
at fair value, which approximates costs, of the investments based on quoted
market prices at December 31, 1998. The Company considered all of these
investments to be available for sale.

 Laboratory Materials and Supplies

   Laboratory materials and supplies are stated at the lower of cost or market.
Cost is determined by the first-in, first-out method.

 Equipment and Leasehold Improvements

   Equipment is carried at cost, less accumulated depreciation, which is
computed on the straight-line basis over the estimated useful lives of the
related assets, which range from two to eight years. Leasehold improvements are
recorded at cost, less accumulated depreciation, which is computed on the
straight-line basis over the shorter of their useful lives or the remaining
lease term. Expenditures for maintenance and repairs are charged to expense as
incurred.

 Goodwill and Other Intangibles

   Goodwill, which represents the excess purchase price over fair value of net
assets acquired, and other intangibles are amortized on a straight-line basis
over its estimated useful lives, as follows:

 Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of

   In accordance with SFAS No. 121, "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company reviews
long-lived assets, certain identifiable intangibles and goodwill for impairment
whenever events or changes in circumstances indicate that the carrying amount
of an asset may not be recoverable. Recoverability of assets to be held and
used is measured by a comparison of the carrying amount of an asset to the
undiscounted future net cash flows expected to be generated by the asset. If
such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceed the
fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to dispose.

 Income Taxes

   The Company accounts for income taxes in accordance with the asset and
liability method prescribed by Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes." Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax basis of assets and liabilities using tax rates in effect for
the years in which the differences are expected to reverse. The measurement of
deferred tax assets is reduced, if necessary, by a valuation allowance for any
tax benefits which are not expected to be realized. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in the period
that such tax rate changes are enacted.

                           December 31, 1998 and 1999


 Revenue Recognition

   On December 3, 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in
Financial Statements." SAB 101 provides the SEC staff's views on the
recognition of revenue including nonrefundable technology access fees received
by registrants in connection with research collaborations with third parties.
SAB 101 states that in certain circumstances the SEC staff believes that up-
front fees, even if nonrefundable, should be deferred and recognized
systematically over the term of the research arrangement. The Company's revenue
recognition policies are consistent with the provisions of SAB 101 and the
accompanying consolidated financial statements reflect this policy for all
periods presented.

   Revenue related to research and development contracts and grants is
recognized when the related research expenses are incurred and the Company's
specific performance obligations under the terms of the respective contract are
satisfied. To the extent expended, funding related to research and development
contracts for equipment is deferred and amortized over the shorter of its
useful life or the life of the related contract. Revenue recognized in the
accompanying consolidated financial statements is not subject to repayment.
Payments, if any, received in advance of performance under the contract are
deferred and recognized as revenue when earned. Up-front licensing fees are
deferred and amortized over the estimated performance period.

   Revenue on DNA laboratory testing and from SNP testing services are
recognized on an accrual basis at the time test results are reported. Deferred
revenue represents the unearned portion of payments received in advance of
tests being completed. Unbilled receivables represent revenue which has been
earned on completed tests which have not been billed to the customer.

   Revenue on product sales is recorded on transfer of title and after all
significant performance obligations of the Company have been met. Revenue from
operating lease transactions is recognized on a straight-line basis over the
term of the lease in accordance with the lease agreement.

 Research and Development

   Costs incurred for research and product development, including costs
incurred in obtaining license rights to technology in the development stage are
expensed as incurred. In addition, the Company recognizes research and
development expenses in the period incurred and in accordance with the specific
contractual performance terms of such research agreements. Costs incurred in
obtaining technology licenses are charged to research and development expense
if the technology licensed has not reached technological feasibility and has no
alternative uses.

 Stock-based Compensation

   The Company accounts for its stock-based compensation to employees and
members of the Board of Directors in accordance with the provisions of
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock
Issued to Employees," and related interpretations. As such, compensation is
recorded on the date of issuance or grant as the excess of the current
estimated fair value of the underlying stock over the purchase or exercise
price. Any deferred compensation is amortized over the respective vesting
periods of the equity instruments, if any. The Company has adopted the
disclosure provisions of Statement of Financial Accounting Standards No. 123
("SFAS No. 123"), "Accounting for Stock-Based Compensation," which permits non-
public entities to provide pro forma net loss and net loss per share
disclosures for stock-based compensation as if the minimum value method defined
in SFAS No. 123 had been applied. As required by SFAS No. 123, transactions
with non-employees, in which goods or services are the consideration received
for the issuance of equity instruments, are accounted for under the fair value
basis in accordance with SFAS 123.

 Use of Estimates

   The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires the Company to make estimates
and assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.

 Net Loss Per Share

   Net loss per share is computed in accordance with SFAS No. 128, "Earnings
Per Share," by dividing the net loss allocable to common stockholders by the
weighted average number of shares of common stock outstanding. As of December
31, 1999, the Company has certain options, warrants, convertible preferred
stock and mandatorily redeemable convertible preferred stock (see notes 11, 12
and 13), which have not been used in the calculation of diluted net loss per
share because to do so would be anti-dilutive. As such, the numerator and the
denominator used in computing both basic and diluted net loss per share
allocable to common stockholders for each year are equal. The Company has
reflected $44,554,000 as a beneficial conversion feature in the net loss
allocable to common stockholders for the Series E mandatorily redeemable
convertible preferred stock ("Series E") issued or issuable in exchange for
cash at December 31, 1999. The amount of the beneficial conversion feature was
calculated as the difference between the fair value of the Company's common
stock on the commitment date of $11.75 per share over the conversion price of
$4.50 per share, with a limitation that the beneficial conversion feature can
not exceed the gross proceeds received from the issuance of the stock.

 Pro Forma Net Loss Per Share (Unaudited)

   The following pro forma basic and diluted net loss per share allocable to
common stockholders and shares used in computing pro forma basic and diluted
net loss per share allocable to common stockholders have been presented
reflecting the automatic conversion into shares of common stock of the
convertible preferred stock and mandatorily redeemable convertible preferred
stock upon completion of the offering contemplated herein (see note 13), using
the if converted method from their respective dates of issuance:

unaudited pro forma balance sheet has been prepared assuming the conversion of
the convertible preferred stock outstanding and the mandatorily redeemable
convertible preferred stock outstanding and to be issued as of December 31,
1999, into common stock as of December 31, 1999.

(2) Acquisition of Molecular Tool, Inc.

   On September 11, 1998, the Company acquired substantially all the assets and
assumed certain liabilities of Molecular Tool, Inc. (MT), a subsidiary of
GeneScreen. The acquisition has been accounted for by the purchase method and,
accordingly, the assets and liabilities acquired have been recorded at their
fair values. The purchase price was approximately $7.1 million of which $3.2
million was paid in cash, $3,548,000 was in the form of a note (see note 7) and
$200,000 represented the fair value of 93,289 Orchid stock options exchanged
for GeneScreen options held by employees of MT and others.

   The purchase price, including acquisition costs of approximately $163,000,
was allocated as follows:

                                                                     ==========
</TABLE>

   The results of operations of MT have been included in the Company's
consolidated financial statements from September 11, 1998.

   Acquired in this transaction were a variety of intellectual property and
intangible assets including Molecular Tool's patent portfolio, assembled
workforce of research and development staff, and base technology upon which its
research efforts were based.

   Molecular Tool was engaged in the development of proprietary technologies
and products for the identification and analysis of DNA sequence variation,
including an approach called SNP-IT, an approach to analyzing large numbers of
DNA samples for a given genetic effect, and the use of genetic variations
called single nucleotide polymorphisms ("SNPs").

   The charge relating to the acquisition of Molecular Tool consists of
acquired in-process research and development of $2,352,838 which was
immediately charged to expense.

   The value of acquired research and development related to this acquisition
represents the fair value of Molecular Tool products and services under
development. These products were associated with the application of SNP and
SNP-IT technologies under development by Molecular Tool as of the closing date
of the transaction. They include SNP Kits valued at $273,000, representing
collections of SNPs contained in plates and arrays to facilitate genetic
analysis; SNP Services valued at $418,000, representing the provision of
genetic analysis by Molecular Tool based on the SNP Kits under development; SNP
OEM equipment and machinery valued at $1.605 million, which is designed to
perform automated genetic analysis based on the technology and procedures
inherent in the SNP Kits; and SNP-IT Chips valued at $57,000, representing a
system permitting genetic analysis to be performed at the level of a silicon
chip in an effort to further automate genetic analysis.

   At the date of acquisition, none of the products or services under
development by Molecular Tool, Inc. had achieved technological feasibility and
none were being sold on the market. There still remained substantial risks and
significant uncertainty concerning the remaining course of technical
development. Key development risks for this product included validation
testing, engineering of stability into the critical reagents to permit their
use in the field, and developing the means of scaling-up manufacturing of the
reagents and other elements of the product for eventual sale. The SNP-IT chips
had been identified and proposed as a new technology development area at the
time of the acquisition. However, major components of the chip had not been
demonstrated as feasible and have required and will continue to require
substantial investment. Areas not yet shown to be feasible included: chip
materials fabrication and biocompatibility; method and composition of bioactive
surface preparation; method and composition of optical detection systems
compatible with chip design. The Mega SNPatron Services, while now more
commercially advanced than the SNP-IT chips, faced the need for development and
feasibility demonstration in several key areas, most notably: method and
composition of the bioarray components; the ability to capture and process
results data from the Mega SNPstream process; and the composition of stable,
viable, and cost effective reagents for the tests. In the case of the SNP OEM
equipment, development of the analysis machine was largely complete but was
still expected to face engineering challenges before ultimate completion. The
challenges faced by SNPstream hardware and SNPware reagents to complete
successful commercialization included: feasibility of adapting an off-the-shelf
robotic system as the SNPstream platform; development of software systems for
data management; and development and validation of viable, stable and cost
effective reagents usable in the SNPware kits. An overall risk facing these
projects was the potential development of competing technologies to facilitate
cost reduction in genetic assays before the Molecular Tool products would even
reach the market.

   Because of the great uncertainty associated with these issues, and both the
uncertainty and remaining effort associated with development for these
products, the Molecular Tool development projects had not established
technological feasibility at the acquisition date. Further, these partially
completed products had no alternative future uses at the valuation date if the
contemplated programs were to fail, as the technology was highly specialized to
the targeted products.

   The estimated values of all acquired intangible assets including the
acquired development projects were determined. Other identified intangibles
included patents, the assembled workforce (principally research and development
personnel), and the base technology of Molecular Tool associated with SNP-IT
and single nucleotide polymorphisms.

   The value of the acquired in-process research and development projects was
determined by projecting expected completion costs for the development projects
as well as projected cash flows resulting from their commercialization.
Material net cash inflows are projected to be realized for the development
programs in 2002, except for the SNP-IT Chip, which was projected at 2003 to
2004. The risk adjusted discount rates applied to the projects' cash flows were
40% for each of the projects except for the SNP-IT Chips, for which the risk
adjusted discount rate was 45%. In the development of projected cash flows a
completion percentage of 60.0% was employed for each project in the calculation
of cash flows to be discounted. The resulting net cash flows implied by this
projection were discounted to present value using an appropriate risk adjusted
cost of capital. This rate was developed by including a risk premium above the
return associated with the valuation of the base technology of Molecular Tool,
and above the observed weighted average costs of capital for comparable
companies involved with the development and sale of similar technologies.

   The following unaudited pro forma financial information presents the
combined results of operations of the Company and Molecular Tool as if the
acquisition had occurred as of January 1, 1997, after giving effect to certain
pro forma adjustments, including amortization of goodwill and other
intangibles, and increased interest

(3) Acquisition of GeneScreen, Inc.

   On December 30, 1999, the Company acquired all of the outstanding shares of
common and preferred stock of GeneScreen in exchange for consideration
consisting primarily of up to 4,000,000 shares of the Company's Series E with a
stated value of $4.50 per share. The note payable to GeneScreen related to the
purchase of the MT assets in the amount of $3,547,821 (see note 7) and certain
other liabilities totalling $421,000 were also cancelled. The acquisition has
been accounted for by the purchase method and, accordingly, the assets and
liabilities acquired have been recorded at their fair values. The Company has
included $28,530,000 as a beneficial conversion feature attributable to the
Series E in the purchase price which was recorded as an increase to additional
paid-in capital. The amount of the beneficial conversion feature was calculated
as the difference between the $11.75 per share fair value of the Company's
common stock on December 22, 1999, the commitment date, over the $4.50 per
share conversion price.

   The net purchase price of $42,711,000, including acquisition costs of
approximately $150,000, was allocated as follows:

   As of December 31, 1999, none of the 4,000,000 shares had been issued. By
January 27, 2000, 3,934,353 shares were issued, which represents all of the
shares which will be issued and which are recorded as Series E mandatorily
redeemable convertible preferred stock to be issued in the December 31, 1999
consolidated balance sheet. Additionally, the Company recorded a liability at
December 31, 1999 of approximately $300,000 representing the 65,647 shares of
Series E which will not be issued and for which cash will be paid in lieu of
issuing Series E shares to satisfy certain regulatory requirements and to
eliminate fractional shares. Of the 4,000,000 shares, shares with a value of $1
million based on the stated value of $4.50 per share, allocated from the
GeneScreen stockholders on a pro rata basis, will remain in escrow for up to
one year to satisfy any claims

based upon any breach of representations and warranties by the GeneScreen
stockholders under the merger agreement or claims based upon any liability of
GeneScreen under ERISA with respect to eligibility requirements under
GeneScreen's 401(k) plan. The $1 million value of these shares has been
included in the recorded purchase price; payment of these shares in
satisfaction of claims would result in a reduction of goodwill. Also, 518,534
of the 4,000,000 shares, when issued, will give the holders the rights to force
the Company to repurchase these shares after certain dates falling within one
year from the acquisition date. These repurchase rights expire upon the closing
of an initial public offering of the Company's common stock with gross proceeds
of at least $25 million. The total value at the date of acquisition of the
Series E to be issued, including the beneficial conversion feature, was
$46,130,000.

   The results of operations of GeneScreen since its acquisition by the Company
on December 30, 1999 through December 31, 1999 have not been included in the
Company's 1999 consolidated statement of operations as they are not material to
those results of operations. The acquisition of GeneScreen is reflected in the
accompanying consolidated balance sheet as of December 31, 1999.

   The following unaudited pro forma financial information presents the
combined results of operations of the Company and GeneScreen as if the
acquisition had occurred as of January 1, 1999, after giving effect to certain
pro forma adjustments, including amortization of goodwill and other
intangibles, decreased interest expense from the cancellation of the Company's
note payable to GeneScreen and elimination of transaction-related costs
incurred by GeneScreen prior to the acquisition. The pro forma financial
information does not necessarily reflect the results of operations that would
have occurred had the Company and GeneScreen constituted a single entity during
this period or the results of operations which may occur in the future.

   Accounts receivable is primarily composed of amounts owed by government
agencies. The Company performs periodic credit evaluations of its customer's
financial condition and generally does not require a deposit from government
agencies or private institutions. The Company believes private pay accounts for
paternity testing represent the most significant credit risk and generally
requires a deposit for all or a portion of the services to be rendered. Credit
losses have consistently been within management's estimates.

(7) Debt

   On September 11, 1998, the Company entered into a subordinated convertible
term note in the amount of $3,547,821 in connection with the MT acquisition.
The note bears interest at 6% per annum and all principal and accrued interest
was to be due September 11, 2008. On December 30, 1999, the note was cancelled
in connection with the acquisition of GeneScreen, the holder of the note (see
note 3).

   In December 1998, the Company entered into a $6,000,000 equipment line of
credit which is secured by the purchased equipment. The funding commitment
terminated in December 1999. All borrowings under the facility are to be
repaid in monthly principal installments plus interest over 48 months from the
date of funding with the final 15% of the original principal amount due in a
balloon payment at the end of loan term. At December 31, 1998 and 1999, $0 and
$4,648,606, respectively, were outstanding under the facility and annual
interest rates on the four draws range from 10.55% to 11.66%. In connection
with this arrangement, 20,894 warrants to purchase common stock were granted
at the time of the borrowings with exercise prices which ranged from $4.50 to
$12.25 per share. The fair value of these warrants of $76,000, as determined
using a Black-Scholes option pricing model, was recorded as debt issuance
costs and is being amortized over the term of the debt.

   GeneScreen had outstanding borrowings under a revolving credit agreement of
$1,000,000 at December 31, 1999. On January 20, 2000, the Company repaid the
balance and cancelled the credit facility. The note was collateralized by
$400,000 of pledged cash and cash equivalents on deposit at the financial
institution until the loan was repaid.

(9) Income Taxes

   No Federal or state taxes are payable as of December 31, 1998 and 1999. As
of December 31, 1999, the Company has approximately $40,000,000 of Federal and
$44,000,000 of state net operating loss ("NOL") carryforwards available to
offset future taxable income. The Federal and state NOL carryforwards will
begin expiring in 2003 if not utilized.

   The Tax Reform Act of 1986 ("the Act") provides for a limitation on the
annual use of NOL carryforwards (following certain ownership changes, as
defined by the Act) which could significantly limit the

Company's ability to utilize these carryforwards. The Company may have
experienced various ownership changes, as defined by the Act, as a result of
past financings and may experience others in connection with future financings,
including the offering contemplated herein. Accordingly, the Company's ability
to utilize the aforementioned carryforwards may be limited. The Company has not
yet determined whether or not ownership changes, as defined by the Act, have
occurred. Additionally, because U.S. tax laws limit the time during which these
carryforwards may be applied against future taxes, the Company may not be able
to take full advantage of these attributes for Federal income tax purposes.

   The tax effects of temporary differences that give rise to significant
portions of the deferred tax assets and liabilities at December 31, 1998 and
1999 are presented below:

   At December 31, 1999, a valuation allowance of $17,450,000 has been
recognized to fully offset the net deferred tax assets as realization of these
assets is uncertain. The net change in the valuation allowance for the years
ended December 31, 1998 and 1999 were increases of $1,878,500 and $11,161,000,
respectively, related primarily to additional net operating losses incurred by
the Company.

(10) Segment Information

   The Company operates in two segments, each of which are strategic businesses
that are managed separately because each business develops, manufactures and
sells distinct products and services. The segments and a description of their
business are as follows: (i) the Company prior to the acquisition of GeneScreen
("Orchid"), which performs SNP scoring analysis and markets related equipment
and consumables; and (ii) GeneScreen, which performs DNA laboratory analysis
for paternity, transplantation and forensic testing.

   The Company evaluates performance of and allocates resources to the
segments. The accounting policies of the segments are substantially the same as
those described in the summary of significant accounting policies, as discussed
in note 1.

   Prior to the acquisition of GeneScreen on December 30, 1999, the Company was
operated and managed as one business. Segment assets as of December 31, 1999
for Orchid and GeneScreen amounted to approximately $52,145,000 and
$42,711,000, respectively. No other segment information is presented as the
1999 activity is that of Orchid only.

   One related party, SmithKline Beecham, accounted for 100%, 99% and 0% of
total revenue for 1997, 1998 and 1999, respectively, under the terms of the
August 1995 Development and License Agreement (see note 11).

(11) Agreements

   In August 1995, the Company entered into an Investment Agreement and a
Development and License Agreement with Sarnoff and SmithKline Beecham ("SB"),
which were amended in 1997 and 1998 (as amended, the "Agreements").

   Under the Agreements, Sarnoff granted to the Company a perpetual, royalty-
free, exclusive, worldwide license for certain technology. In addition, Sarnoff
agreed to provide, for standard fees paid by third-parties, contract research
services necessary under the Agreements to the Company. In consideration for
the license, the Company issued 670,000 shares of Series A convertible
preferred stock ("Series A") to Sarnoff. No value was ascribed to the license
or the stock as the Company was controlled by Sarnoff at the time and because
the license had a carrying value of $0 on Sarnoff's books. In 1997, 1998 and
1999, Sarnoff provided contract research services of $9,121,641, $2,056,953 and
$930,677, respectively. The Company's office was also located in the Sarnoff
facility until 1998 and Sarnoff provides certain administrative support, for
which the Company paid Sarnoff; expenses related to these items totalled
$114,636, $251,449 and $63,519 in 1997, 1998 and 1999, respectively. Certain
administrative costs were allocated from Sarnoff based on either a usage
percentage of actual costs or an approximation of market rates in the case of
rent. Management believes these allocation methods are reasonable. A total of
$381,033 and $63,519 is recorded as due to related party in the accompanying
balance sheets at December 31, 1998 and 1999, respectively, related to these
items.

   The Company and Sarnoff also issued to SB a license to technology which may
result from this research, subject to certain potential future payments from SB
to allow SB to retain exclusivity. The Company also agreed to sell products
developed under the contract to SB at prices to be determined per the
Agreements. SB also granted to Orchid certain non-exclusive licenses (the
"Licenses") which Orchid may require in conducting research or producing
products developed under the contract.

   In accordance with the Agreements, in October 1995, SB purchased 41,667
shares of Series B convertible preferred stock ("Series B") for $800,000. SB
also agreed to provide research and development funding of up to approximately
$16 million for the design and testing of a product for certain applications
and is required to make further payments of up to $8 million upon the
achievement of certain technical milestones. The Company met its first
milestone in 1996 and received a milestone payment of $1.5 million and issued
26,973 shares of Series B to SB. The Company allocated $517,882 of this amount
to the Series B shares, which was the fair value at the time of issuance and
recorded the remaining $982,118 of this milestone payment as contract revenue.
The Company paid $350,000 of this amount to Sarnoff as a milestone payment. In
1997, SB advanced a portion of the second milestone payment. This advance
totaled $1,320,000 and was recorded as a milestone advance at December 31,
1997. In 1998, the Company and SB entered into an agreement acknowledging that
a portion of the second milestone had been accomplished and therefore, a
portion of the second milestone payment equal to the $1,320,000 milestone
advance was therefore earned and non-refundable. No further performance
obligations remained related to this acknowledged portion of the milestone.
They also agreed that SB would receive 35,200 shares of Series B, the number of
shares proportionate to the milestone fee earned. Those shares were issued in
1999. The Company allocated $211,200 of this amount to the Series B shares,
which was the fair value at the time of the agreement and recorded the
remaining $1,108,800 of this milestone payment as contract revenue. Any future
milestone payments are subject to reduction for cost overruns funded by SB or
delays in the timing of the performance of the milestones and the Company is
obligated to pay Sarnoff 10% of any future milestone payments received. Any
payments to Sarnoff will be capitalized to the extent that the technology has
reached technological feasibility or has alternative uses; otherwise the
payments will be expensed to research and development. The Company is required
to issue a total of up to 96,533 additional shares of Series B for no
additional consideration upon the payment by SB to the Company of these

                           December 31, 1998 and 1999

remaining milestones. During 1997, 1998 and 1999 the Company recognized
contract revenue from SB of $3,763,000, $2,747,800 and $0 in the accompanying
consolidated statements of operations.

   In December 1997, in consideration for an amendment of the Agreements, the
Company issued to SB an additional 75,000 shares of common stock and warrants
to purchase 275,000 shares of common stock at an exercise price of $11.10 per
share. The deemed fair value of the shares of common stock was $168,750, which
was recorded as research and development expense in the accompanying 1997
consolidated statement of operations. No value was ascribed to the warrants
based on the fair value as determined using a Black-Scholes option pricing
model. Warrants to purchase 138,000 shares of common stock became exercisable
immediately with the 137,000 remaining warrants vesting upon the payment of the
next milestone payment to the Company. All of these warrants expire in December
2002. Also, the Company is obligated to issue up to an additional 20,000 shares
of common stock to SB upon the exercise of certain options to acquire
additional licenses for technology under the License and Option Agreement
discussed below. As of December 31, 1998 and 1999, the Company is obligated to
issue 5,000 and 10,000 shares (including the 5,000 shares from 1998) of common
stock, respectively, to SB related to the option fields exercised by the
Company in 1998 and 1999, respectively. The fair value of these 5,000 shares of
common stock in 1998 and 1999 was $17,500 and $58,750, respectively, and has
been recorded as research and development expense in the accompanying
consolidated statements of operations. Common stock to be issued has been
recorded in the amounts of $17,500 and $76,250 at December 31, 1998 and 1999,
respectively. These 10,000 shares were issued in February 2000.

   Pursuant to a December 1997 amendment to the Development and License
Agreement, the Company committed to fund $3.5 million of research within the
scope of the original Agreements and $3.0 million outside of the original scope
and solely for the benefit of SB. In exchange, the Company received new rights
to certain technology previously developed under this agreement. As the Company
was obligated to incur these costs in fulfilling the terms of the Agreements
without any increase in corresponding contract revenue, and as this technology
to which the rights were received has not reached technological feasibility and
has no alternative future uses, the acquisition of these rights for $3.0
million was recorded as research and development expense in 1997. The Company
fulfilled its obligation and incurred these costs during 1998.

   In December 1997, the Company entered into a License and Option Agreement
("Option Agreement") with Sarnoff under which the Company has options to obtain
exclusive licenses for the use of certain technology in four designated areas:
genomics, certain high throughput screening, analysis and synthesis and cell-
based assays. In addition, the Company obtained non-exclusive and exclusive
licenses in a certain field. In consideration of the licenses obtained under
the Option Agreement, the Company issued to Sarnoff 82,500 shares of common
stock, with a fair value of $185,626 and 167,500 shares of Series A, with a
fair value of $1,289,750, of which both amounts were recorded as research and
development expense in the accompanying 1997 consolidated statement of
operations. The options expire one per year over a four year period with
certain extension provisions as defined in the Option Agreement. Concurrent
with the exercise of each option, the Company is obligated to issue 33,300
shares of common stock and 66,700 shares of Series A to Sarnoff and to fund
research to be performed by Sarnoff at an amount as defined in the contract,
but no less than a total of $5.5 million over 4 years. In both December 1998
and 1999, the Company exercised one of its options under the Option Agreement.
In consideration for the options, the Company issued to Sarnoff 33,300 shares
of common stock in each of 1998 and 1999, with a fair value of $114,885 in 1998
and $391,275 in 1999, and 66,700 shares of Series A in each of 1998 and 1999,
with a fair value of $400,200 in 1998 and $783,725 in 1999, which amounts were
recorded as research and development expense in the accompanying 1998 and 1999

consolidated statements of operations. All of the amounts noted above which
were paid as consideration for licensed technology have been recorded as
research and development expense as the technology licensed has not reached
technological feasibility and has no alternative uses.

   In addition, the Company is obligated to issue an additional 50,000 shares
of common stock to Sarnoff at the end of each year during the term of the
research for each option exercised. Accordingly, the Company issued 50,000
shares of common stock in 1999 to Sarnoff related to the option exercised in
December 1998. The fair value of this stock was $587,500, which was recorded as
research and development expense in the accompanying 1999 consolidated
statement of operations. The Company is also required to make royalty payments
as set forth in the Option Agreement on future net sales of products and
services derived from these licenses, if any.

   On March 27, 1998, the Company entered into a license agreement with
Motorola, Inc. ("Motorola"). In 1999, Motorola exercised an option to acquire a
license under this agreement, effective January 1, 2000, by making a $100,000
payment. This amount has been recorded as deferred revenue at December 31, 1999
and will be recognized over the estimated term of the license. The Company also
issued an option to Motorola to purchase up to $5,000,000 of common stock at a
per share price of the lesser of $33.30 or 110% of the average closing price of
the common stock for the ten days following an initial public offering. No
value was ascribed to the option based on the fair value as determined using a
Black-Scholes option pricing model. The option expired unexercised on December
15, 1999.

   On November 11, 1998, the Company entered into a Collaboration Agreement
with Motorola to jointly perform certain research and development activities.
Motorola intended to invest cash or in-kind payments of at least $5 million
over a 30 month period in these activities. Total cash payments of at least
$1.7 million were to be made to the Company for services in support of the
collaboration. Motorola made a payment to the Company in 1998 of $250,000,
which was recorded as deferred revenue as of December 31, 1998 and which was
recognized as revenue in 1999 as the related research and development
activities were performed. On October 25, 1999, this agreement was terminated
as allowed under the Collaboration Agreement, causing all research and
development activities to cease. In 1999, Motorola made additional payments
under this agreement aggregating $505,000, of which the Company recognized
$245,000 as revenue as the related research and development activities were
performed and $260,000 is recorded as a liability at December 31, 1999 as it
relates to work which will not be performed given the termination of the
agreement. In accordance with the terms of the Collaboration Agreement, the
Company has also recorded approximately $333,000 as contract revenue-unrelated
party in 1999 and as a termination fee receivable at December 31, 1999 and will
be reimbursed for certain shutdown costs not to exceed $178,000 in connection
with the termination. The Company does not expect that shutdown costs will
exceed $178,000.

   On April 1, 1998, the Company entered into a license agreement with Dynal
A.S. whereby the Company issued 90,090 shares of common stock for an exclusive
license. The fair value of the stock, $247,748, has been recorded as research
and development expense in the accompanying 1998 consolidated statement of
operations.

   In February 1999, the Company and Cytomics, A.S. ("Cytomics") entered into a
Collaborative Research and License Agreement whereby Cytomics will perform
research on the Company's behalf with the Company's financial support and
granted to the Company a non-exclusive, royalty-free, worldwide license for
certain technology. Prior to executing the agreement in February 1999, the
Company made payments to Cytomics of $345,000, for which services were
performed and which was recorded as research and development expense in 1998.
The agreement was terminated, effective June 30, 1999. The Company recorded
research and development expense of $110,000 in 1999.

                           December 31, 1998 and 1999


   In September 1998, the Company entered into a Cooperative Agreement with the
National Institute of Standards and Technology ("NIST") to perform certain
research and development. The total amount expected to be provided to the
Company over the three year period of January 1, 1999 through December 31, 2001
is $1,954,000; however no obligation exists for the federal government to
provide any portion of the 2001 funding. Funding in 1999 amounted to $690,000
which was recorded as grant revenue and $602,000 in funding for 2000 has been
approved. The anticipated funding for the year 2001 is $662,000. The award in
1999 was conditional upon the Company's funding of indirect costs aggregating
$319,000 in 1999 which was incurred by the Company. To receive full funding in
2000 and 2001, the Company's funding of indirect costs must aggregate $309,000
and $385,000 in 2000 and 2001, respectively.

   On December 31, 1998, the Company entered into a Collaborative Development
and Marketing Agreement with Advanced Bioanalytical Services, Inc. ("ABS")
under which Orchid obtained a license. Per the terms of the agreement, both
parties are to conduct certain research and development activities based upon a
mutually agreed upon budget and each party will bear their respective costs.
The Company paid ABS a non-refundable $100,000 license fee payment upon signing
the agreement, which was recorded as research and development expenses in 1998.
In 1999 upon certain technological achievements by ABS, the Company made
milestone payments aggregating $225,000 to ABS, all of which was recorded as
research and development.

   In October 1999, the Company entered in a one year license and supply
agreement with a licensee to provide an instrument, consumables and related
support for automated SNP scoring analysis. As consideration for use of the
instrument for the one year, the licensee paid $500,000 license fee, which is
refundable on a pro-rata basis upon certain events. The licensee is obligated
to purchase a minimum order of consumables which are billed separately when
purchased and may elect to purchase the instrument from the Company for an
additional payment. The licensee may terminate the contract, in which case the
Company would be entitled to a termination fee of $100,000 and to bill the
remaining minimum amount of consumables to the licensee. As of December 31,
1999, the Company has recognized approximately $104,000 of the license fee and
deferred the remaining $396,000. The remaining deferred license fee will be
recognized on a straight-line basis over the remaining term of the agreement.

   On November 5, 1999, the Company entered into a collaboration agreement with
Affymetrix, Inc. ("Affymetrix"), for the Company to develop, manufacture, and
for both parties to market and sell specific products. Each party is
responsible for costs associated with their respective development
responsibilities. The Company agreed to collaborate on the development of three
types of kits, designated under our agreement as Generic Kits, Standard Kits
and Custom Kits. The Company is responsible for all development costs
associated with the development of Generic Kits and Custom Kits and the
optimization of the SNP-IT primer-extension tests to be used on the Affymetrix
GeneChip system. The Company and Affymetrix will share costs associated with

Generic and Standard Kits developed under the agreement, and we will market and
distribute all Custom Kits. Affymetrix has agreed to purchase, and we have
agreed to manufacture and supply, all of Affymetrix's requirements of Generic
and Standard Kits at agreed upon prices. The agreement is for an initial term
of five years and is renewable for additional one-year terms by mutual
agreement.

(12) Stock Incentive Plan

   During 1995 the Company established the 1995 Stock Incentive Plan (the
"Plan"), which provides for the granting of restricted common stock or
incentive and nonqualified stock options to directors, employees and
consultants. An aggregate of 1,500,000 shares of the Company's common stock is
authorized to be issued under the Plan. The options are exercisable generally
for a period of ten years after the date of grant and

                           December 31, 1998 and 1999

generally vest over a four-year period. The Plan provides that in the event of
a change in control in the beneficial ownership of the Company, as defined, all
options may at the discretion of the compensation committee become fully vested
and exercisable immediately prior to the change in control. The plan also
specifies other terms such as eligibility and annual limits.

   The Company applies APB Opinion No. 25 in accounting for its stock option
plan. In 1997, 1998 and 1999, certain employees of the Company were granted
options to acquire 170,130, 322,575 and 870,329 shares of common stock,
respectively. The weighted average fair values of common stock for the years
ended December 31, 1997, 1998 and 1999 were $1.26, $2.95 and $5.58 per share,
respectively. The difference between the respective exercise prices at the
grant dates and the fair value of the common stock on the dates of grant, as
determined by the Board of Directors, has been recorded as deferred
compensation ($291,700, $308,488 and $6,994,552 for 1997, 1998 and 1999,
respectively) which is being amortized on a straight-line basis to expense over
the respective vesting periods.

   In 1997, 1998 and 1999, the Company granted options to certain non-employees
to purchase 41,600, 95,463 and 87,200 shares of common stock, respectively.
Such options vest over a three or four year period based upon future service
requirements. The Company recorded deferred compensation of $22,862, $129,812
and $1,085,284 for 1997, 1998 and 1999, respectively, based on the fair value
at the grant date as determined using a Black-Scholes option pricing model.
Such deferred compensation is being amortized to expense using the methodology
prescribed in FASB Interpretation No. 28 over the respective vesting periods.
In accordance with EITF Issue 96-18, the amount of compensation expense to be
recorded in future periods related to the 1998 and 1999 grants is subject to
change each reporting period based upon changes in the fair value of the
Company's common stock, estimated volatility and risk free interest rate until
the non-employee completes performance under the option agreement. Additional
deferred compensation in the amount of $857,235 was recorded in 1999 related to
the remeasurement of the 1998 grants. 146,316 options subject to this treatment
remain unvested at December 31, 1999.

   The per share weighted-average minimum value of the stock options granted to
employees during 1997, 1998 and 1999 was $1.71, $2.15 and $8.71 per share,
respectively, on the date of grant. The per share weighted-average fair value
of stock options granted to non-employees during 1997, 1998 and 1999 was $.79,
$2.39 and $7.34 per share, respectively, on the date of grant. Such values were
determined using the minimum value method for employees and the Black Scholes
option-pricing model for non-employees with the following weighted-average
assumptions: expected dividend yield 0%; risk free interest rate of 6.5% for
1997, 5.0% for 1998 and 5.0% for 1999; volatility is not applicable for
employees as the Company is private and 60% in 1997, 70% in 1998 and 1999 for
non-employees; and an expected option life of 7 years for employees and 10
years for non-employees.

(13) Mandatorily Redeemable Convertible Preferred Stock, Convertible Preferred
Stock and Common Stock

   On December 24, 1997, the Company completed the sale of 1,101,801 shares of
Series C mandatorily redeemable convertible preferred stock ("Series C"),
through a private placement for $11.10 per share. The Company received cash
proceeds of $9,230,000 in 1997 and recorded a stock subscription receivable of
$3,000,000 at December 31, 1997, which was subsequently received in January
1998. On March 27, 1998, the Company completed the sale of 1,378,375 shares of
Series C, through a private placement, for $11.10 per share.

                           December 31, 1998 and 1999


   In May and June 1999, the Company issued an aggregate of $7,590,000 of
convertible subordinated term notes and warrants to purchase 381,500 shares of
the Company's common stock. The notes were to be convertible into Series E at
$6 per share, subject to adjustment, at any time at the option of the holder or
automatically upon the closing of a private placement financing with proceeds
of at least $24 million. The note bore interest at prime plus 2%. In December
1999, the principal plus accrued interest of approximately $436,000 were
automatically converted into 1,783,509 shares of Series E at a conversion price
of $4.50, the price per share in the Series E financing, in accordance with the
original conversion terms, with this combined amount being recorded as Series
E. Based upon the issuance price per share of the Series E and the conversion
not occurring until December 1999, 382,410 additional warrants are to be issued
related to these convertible subordinated term notes. All warrants have an
exercise price of $1.25 per share and are exercisable for five years. The fair
value of the originally issued and additional warrants, using a Black Scholes
option pricing model, was approximately $5,232,000 and was recorded as interest
expense in 1999 and an increase in additional paid-in capital.

   In November 1999, Affymetrix paid the Company $2,250,000 in consideration
for a convertible promissory note. The note bears interest at the prime rate
plus 2%. In December 1999, on closing of the sale of Series E, the principal
and accrued interest in the amount of $2,276,537 should have automatically
converted into Series E. As the Series E was not issued, the amount is shown as
Series E to be issued at December 31, 1999. In a separate agreement, Affymetrix
granted the Company two put options to sell $250,000 of common stock of the
Company at $9.00 per share for each put as a means of providing additional
equity financing to the Company. One put option becomes exercisable upon the
closing of the acquisition of GeneScreen and the other becomes exercisable upon
a certain type of kit contemplated under the collaboration agreement with
Affymetrix having been developed, manufactured and ready for commercial
release. Neither put was exercisable and each had a fair value of $0 at
issuance at which time the fair value of the Company's common stock was $11.75
per share. Upon the closing of the Gene Screen acquisition in December 1999,
one of the puts became exercisable, however, the Company has not exercised its
option as of December 31, 1999. These put options expire in December 2001. If
these puts are exercised, the proceeds will be recorded in stockholders'
equity.

   In December 1999, the Company completed the sale of 6,151,457 shares of the
Series E, through a private placement for aggregate net proceeds of
$31,008,818. In connection with this sale, the Company will issue five year
warrants to purchase 86,334 shares of common stock at an exercise price of
$6.00 per share. The Company recorded $753,000 of additional paid-in capital
based on the fair value of these warrants as determined using a Black-Scholes
option pricing model.

   The Company has reflected $44,554,000 as a beneficial conversion feature in
the net loss allocable to common stockholders for the Series E mandatorily
redeemable preferred stock issued or issuable in exchange for cash in
accordance with EITF Issue 98-5.

   The Series A and Series B are not entitled to any dividends. The Series C,
Series D and Series E shall be entitled to receive dividends if and when
declared by the Board of Directors. No dividends were declared in 1997, 1998 or
1999.

   On or after December 2002 and 2004, at the request of holders of not less
than 66-2/3 percent of the then outstanding shares of Series C and Series E,
respectively, the Company is required to redeem the outstanding shares of
Series C and Series E of those requesting stockholders at $11.10 and $4.50 per
share, respectively, in three equal annual installments plus any accrued but
unpaid dividends.

   The holders of Series A, Series B, Series C, and Series D are entitled to
vote that number of shares of common stock into which each respective share of
preferred stock held by such holder could be converted.

Each share of Series A, Series B, Series C, Series D and Series E is
convertible into one share of common stock, subject to adjustment, (i) at the
option of the holder at any time (prior to any redemption as noted above for
the Series C and Series E) or, (ii) automatically at the closing of a
registration statement under the Securities Act of 1933 for the sale of the
Company's common stock with a gross offering price of at least $15 million for
the Series A, Series B and Series D and for the Series C and Series E both a
gross offering price of at least $25 million and a per share price of at least
$15, subject to adjustment.

   Upon liquidation, dissolution or winding up of the Company, the holders of
Series B, Series C and Series E are entitled to liquidation preferences over
all other types of capital stock as follows: $19.20 per share and the Licenses
for the Series B, $11.10 per share plus an amount equal to any declared but
unpaid dividends for the Series C and $4.50 per share plus an amount equal to
any declared but unpaid dividends for the Series E. The Series A stockholder is
entitled to the license originally granted (if Sarnoff continues to own all
Series A), or its fair value in cash as consideration for the Series A shares.
The holders of Series D are entitled to a liquidation preference of $12.25 per
share plus an amount equal to any declared but unpaid dividends, after payment
in full of all amounts required to be distributed to the holders of Series A,
Series B, Series C and Series E. After these liquidation payments, holders of
the common stock and Series C and Series E would share ratably in the remaining
assets of the Company.

   In 1997, the Company issued 109,333 shares of restricted common stock to an
executive officer of the Company. The shares vested over a two year period. The
deemed value of this stock was $131,766 which was recorded as deferred
compensation and was amortized to expense over the vesting period.

   In 1997 and 1998, the Company issued warrants to purchase 60,000 and 25,000
shares of common stock at $11.10 and $12.25 per share, respectively, to an
executive officer of the Company. The warrants vest based upon specific
performance criteria, which were met for 70,000 warrants by December 31, 1999.

(14) Employee Benefit Plan

   Effective January 1, 1999, the Company sponsors a defined contribution
401(k) savings plan (the 401(k) Plan) covering all employees of the Company.
Participants can contribute up to 15% of their pretax annual compensation to
the 401(k) Plan, subject to certain limitations. The Company matches 50% of the
participant's contribution, up to 4% of compensation. For 1999, the Company's
contributions amounted to $119,452 in accordance with the terms of the Plan.

(15) Commitments and Contingencies

   The Company leases office and laboratory facilities under noncancellable
operating lease arrangements. Future minimum rental commitments required by
such leases as of December 31, 1999 are as follows:

 Legal Matters

   The Company is not a party to any material legal proceeding. The Company is
engaged in discussions with Motorola in an attempt to resolve certain areas of
disagreement that have arisen under the existing collaboration in the area of
microfluidics. The primary issue of disagreement between the parties relates to
whether, under the terms of the agreement with Motorola, Motorola has a right
to obtain a license to the Company's SNP-IT technology for use with Motorola's
microfluidic chips. While the Company believes that, under the terms of the
agreement, Motorola has no rights to its SNP-IT technology, there can be no
assurance that an agreement can be reached with Motorola on this issue or that
the Company would prevail if this dispute were to develop into arbitration or
litigation. Nonetheless, the Company believes that, even if it fails to
successfully resolve this issue or to prevail in any such arbitration or
litigation, it would only be obligated to grant Motorola a non-exclusive
license to use its SNP-IT technology with their microfluidic chips on terms no
less favorable than those offered to other licensees. The Company does not
believe that such a result is likely to have a material adverse affect on the
Company's business, financial condition and operating results.

 Self-Insurance Reserve

   GeneScreen is self-insured for the risk of loss relating to certain
litigation claims that might arise from GeneScreen's testing results. However,
due to provisions in certain service contracts, GeneScreen is insured for
claims arising from testing performed under the Texas, Ohio and Arizona
contracts. Insurance coverage began in 1995 for testing under the Texas
contract, in 1997 for testing under the Ohio and Arizona contracts and all
other contracts in August 1998. Management estimates future litigation costs
based on historical litigation experience. The accrued litigation reserve for
the self-insured risk at December 31, 1999 was $191,000.

(16) Subsequent Events

 Employment agreements

   Effective January 2000, we entered into three year employment agreements
with two executives of the Company. In certain cases, the Company may be
obligated to pay the executives salary and benefits for up to eighteen months
after leaving the Company.

 Change in Authorized Shares

   In January 2000, the Company amended its Certificate of Incorporation to
change the authorized number of shares as follows: Common stock to 30,000,000
shares and Series E convertible preferred stock to 19,000,000 shares.

 Sale of Convertible Preferred Stock

   In January 2000, the Company completed the sale of 5,971,903 shares of
Series E for gross proceeds of $29,573,564. The issuance of these securities
will result in a $29,573,564 beneficial conversion feature which will increase
net loss per share allocable to common stockholders in the first quarter of
2000. The fair value of the Company's common stock on the commitment date was
$11.75; however, the amount of the beneficial conversion feature was limited to
the amount of gross proceeds received from the issuance of the Series E. The
Company also issued 1,040,341 shares of Series E related to the conversion of
the Affymetrix convertible promissory note (see note 13) and for cash received
by December 31, 1999 for which shares were not issued, and which was included
in Series E to be issued at December 31, 1999.

price of the offering contemplated herein, respectively, for which a
compensation charge of approximately $4.2 million will be recognized over the
respective vesting periods of the options. Some of these amounts result from
grants to consultants which are subject to remeasurement at the end of each
reporting period based upon the changes in the fair value of the common stock
until the consultant completes performance under the option agreement. In
addition, the Company issued 855,000 performance based stock options at
exercise prices of $6.00 for which compensation expense will be measured as the
difference between the fair value of our common stock, at the time the
performance criteria is met and the external price and will be immediately
recorded as compensation expense.

 Initial Public Offering

   On February 11, 2000, the Board of Directors authorized the filing of a
registration statement with the SEC for the sale of shares of common stock. If
the offering is consummated under the terms presently anticipated, all shares
of Series A, B, and E stock outstanding as of the closing date of the Offering
will automatically convert into shares of common stock on a one-for-one basis.
The 2,480,176 shares outstanding of Series C will convert into 4,833,356 shares
of common stock. No dividends will be payable on any of the Series A, B, C, or
E.

 Change in Authorized Shares

   On February 11, 2000, the Board of Directors approved filing a restated
certificate of incorporation effective upon the closing of the offering
contemplated herein which would increase the authorized shares of common stock
to 50,000,000 shares, all existing preferred stock designations will be revoked
and 5,000,000 shares of preferred stock will be authorized. The Board of
Directors will have the authority, without any further stockholder approval to
determine the price, privileges and other terms of the shares.

 2000 Employee, Director and Consultant Stock Incentive Plan

   On February 11, 2000 and March 17, 2000, the Board of Directors and
stockholders approved, respectively, the 2000 Employee, Director and Consultant
Stock Incentive Plan for the issuance of common stock, incentive stock options
and non-qualified stock options to employees, directors and consultants. The
Board of Directors also authorized the granting of up to a total of 1,500,000
options under this plan and 3,500,000 under the 1995 Stock Incentive Plan.

 ABS Termination

   Effective February 15, 2000, the Collaborative Development and Marketing
Agreement with ABS was terminated, with Orchid paying ABS $75,000 in full and
final settlement of all amounts owed under this agreement.

 NEN Agreement

   On February 21, 2000, we entered into an Agreement with NEN Life Science
Products, Inc. pursuant to which NEN has agreed to supply us with terminators
for use in our SNPkits. In consideration of NEN's agreement to supply us with
terminators at favorable prices, we sold 125,000 shares of our common stock for
a purchase price of $750,000 and paid NEN an up-front fee of $750,000. We also
agreed to pay NEN a certain percentage of net sales revenue based on the number
of SNPkits we sell. The 125,000 shares had a fair value of $1,500,000 on the
date of the agreement. Since the products being supplied are used in Orchid's

products and may be used in future products, the Company will defer and
amortize the $750,000 up-front fee plus the $750,000 excess of the fair value
of the issued common stock over the purchase price (or a total of $1.5 million)
over the estimated four year term of the agreement on a straight-line basis. We
are required to purchase quantities of products with an approximate minimum
value during each annual period from the effective date as follows: first year
$333,000, second year $700,000, third year $990,000 and fourth year $1,320,000.
Either party can terminate the agreement any time after four years from the
commencement date, without cause, upon 90 days written notice.

 Grant of Stock Options

   On March 31, 2000, the Company granted 289,660 stock options under the Plan
at exercise prices of $12 per share for which a compensation charge of
approximately $800,000 will be recognized over the respective vesting periods
of the options. Some of these amounts result from grants to consultants which
are subject to remeasurement at the end of each reporting period based upon the
changes in the fair value of the common stock until the consultant completes
performance under the option agreement.

 Sarnoff Agreement

   On April 13, 2000, we amended our Option Agreement with Sarnoff. Under the
terms of the amendment in lieu of all future cash payment, research funding,
potential royalty payment and stock issuance obligations, the Company made a
payment to Sarnoff of approximately $3 million and issued 250,000 shares of
common stock and granted five-year warrants to purchase 75,000 shares of common
stock at the initial public offering price, or at $12 per share if there has
been no initial public offering one year after issuance of the warrant. The
Company will also not be able to exercise the remaining two option fields as a
result of this amendment. Previously on February 2, 2000, the Company issued
100,000 shares of common stock to Sarnoff as an advance on the issuances which
would be owed in December 2000 for the two option fields previously issued
under the Option Agreement. As this licensed technology has not reached
technological feasibility and has no alternative future uses, the cash payment
of approximately $3.0 million and the fair value of the equity securities of
approximately $4.8 million will be charged to research and development expense
in the quarter ended June 30, 2000.

 Change in Automatic Conversion Terms

   After previously obtaining requisite stockholder approval, on May 1, 2000,
the Company filed an amendment to its certificate of incorporation to reduce
the per share price required in an initial public offering to automatically
convert shares of Series C and Series E into shares of common stock to be
consistent with the $11.00-$13.00 per share price range contemplated in this
offering.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                    December 31, 1998 and December 29, 1999

(1) Summary of Significant Accounting Policies

 Organization and Business Activities

   GeneScreen, Inc. ("GeneScreen" or the "Company") operates genetic testing
laboratories in Dallas, Texas; Dayton, Ohio (acquired in 1992); and Sacramento,
California (acquired in 1994). GeneScreen performs paternity testing, forensic
identification testing to assist in criminal investigations and medical genetic
testing using technologies developed at the University of Texas Southwestern
Medical Center and other medical research facilities. GeneScreen's primary
sources of revenue represent paternity testing under contracts with several
state government agencies and genetic testing under grants from the National
Marrow Donor Program.

   On September 11, 1998, the Company sold the assets of its Molecular Tool
("MTool") division to Orchid BioSciences, Inc. ("Orchid") (see Note 2). Prior
to this sale, MTool performed research and development activities for third
parties under contract and for its own account and developed and patented a
proprietary technology called SNP-IT primer-extension technology ("SNP-IT") for
the analysis of DNA.

   GeneScreen was acquired by Orchid on December 30, 1999 (see Note 11).

 Consolidated Financial Statements

   The consolidated financial statements include the accounts of GeneScreen and
its wholly owned subsidiaries. Significant intercompany balances and
transactions are eliminated in consolidation.

 Use of Estimates

   Financial statement preparation requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingencies 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.

 Laboratory Materials and Supplies

   Laboratory materials and supplies are stated at the lower of cost or market.
Cost is determined by the first-in, first-out (FIFO) method.

 Property and Equipment

   Property and equipment are stated at cost. Depreciation on equipment is
calculated on the straight-line method over the estimated useful lives of the
assets, which range from two to seven years. Leasehold improvements are
amortized straight line over the shorter of the lease term or estimated useful
life of the asset.

 Financial Instruments

   Financial instruments consist of cash, accounts and notes receivable,
payables and notes payable, the carrying value of which approximate their fair
values due to their short maturities or current interest rates.

 Revenue Recognition

   Revenue is recognized on an accrual basis at the time test results are
reported. Deferred revenue represents the unearned portion of payments received
in advance of tests being completed. Unbilled receivables represent revenue
which has been earned on completed tests which have not been billed to the
customer.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                    December 31, 1998 and December 29, 1999


 Research and Development and Advertising

   Costs incurred for research and product development and advertising are
expensed as incurred. The results of operations for the MTool research and
development facility sold during 1998 are reported as discontinued operations
(see note 2). Advertising costs totalled $131,237 and $47,262 in 1998 and 1999,
respectively.

 Stock-based Compensation

   The Company accounts for its stock-based compensation to employees in
accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25, "Accounting for Stock Issued to Employees", and related
interpretations. As such, deferred compensation is recorded on the date of
issuance or grant as the excess of the fair value of the underlying stock over
the purchase or exercise price. Any deferred compensation is amortized over the
respective vesting periods of the equity instruments, if any. The Company has
adopted the disclosure provisions of Statement of Financial Accounting
Standards No. 123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation,"
which permits entities to provide pro forma net income (loss) disclosures for
stock-based compensation as if the minimum value method defined in SFAS No. 123
had been applied. As required by SFAS No. 123, transactions with non-employees
in which goods or services are the consideration received for the issuance of
equity instruments are accounted for under the fair value based method.

 Income Taxes

   The Company accounts for income taxes in accordance with the asset and
liability method prescribed by Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes." Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax basis of assets and liabilities using tax rates in effect for
the years in which the differences are expected to reverse. The measurement of
deferred tax assets is reduced, if necessary, by a valuation allowance for any
tax benefits which are not expected to be realized. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in the period
that such tax rate changes are enacted.

 Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of

   In accordance with SFAS No. 121, "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company reviews
long-lived assets, certain identifiable intangibles and goodwill for impairment
whenever events or changes in circumstances indicate that the carrying amount
of an asset may not be recoverable. Recoverability of assets to be held and
used is measured by a comparison of the carrying amount of an asset to the
undiscounted future net cash flows expected to be generated by the asset. If
such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceed the
fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to dispose.

 Reclassifications

   Certain reclassifications have been made in the 1998 consolidated financial
statements to conform to the 1999 presentation.

(2) Discontinued Operations of Molecular Tool, Inc.

   In May 1998, the Board of Directors approved a plan to sell the MTool
assets, except that the Company retained certain rights to the SNP-IT
technology of MTool to permit the Company to continue implementation of the
SNP-IT testing processes.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                    December 31, 1998 and December 29, 1999


   In September 1998, the MTool assets were acquired by Orchid. GeneScreen
received $2,806,807 in cash and $3,547,821 in a subordinated convertible note
receivable, and $380,000 was placed in escrow.

   The escrow was to be released to GeneScreen by Orchid upon approval by
certain Federal regulatory agencies of Orchid as a valid recipient of
outstanding MTool grant funds and totaled $380,000 and $0 at December 31, 1998
and December 29, 1999. The note receivable of $3,547,821, bears interest at 6%
annually, and is due on September 11, 2008. As part of this agreement,
GeneScreen retained a lien on the existing MTool patents until settlement of
this note has occurred. This note was cancelled in the acquisition of
GeneScreen by Orchid (see note 11).

   This sale resulted in a gain for the Company of $6,205,297. Of this amount,
$3,927,821, which is equal to the convertible note receivable plus the escrow,
was deferred at December 31, 1998, until the respective settlements of these
items occur. The convertible note receivable was cancelled as part of the
acquisition by Orchid (see note 11) and the escrow funds of $380,000 were
received in 1999 and $357,175 was recorded as a gain, net of tax.

   The accompanying consolidated financial statements include the Company's
investment in MTool on the equity basis and MTool's operations as discontinued
operations. The Company's investment, on the equity basis, in the net assets of
MTool at the time of the sale on September 11, 1998 was determined as follows:

   GeneScreen's accounts receivable are primarily composed of amounts owed by
government agencies. GeneScreen performs periodic credit evaluations of its
customers' financial condition and generally does not require a deposit from
government agencies or private institutions. GeneScreen believes private pay
accounts for paternity testing represent the most significant credit risk and
generally requires a deposit for all or a portion of the services to be
rendered. Credit losses have consistently been within management's estimates.

(4) Property and Equipment

   Property and equipment at December 31, 1998 and December 29, 1999 consist of

(7) Income Taxes

   As of December 29, 1999, the Company has approximately $5,074,000 of Federal
and $2,261,000 of state net operating loss ("NOL") carryforwards available to
offset future taxable income. The Federal and state NOL carryforwards will
begin expiring in 2003 and 2002, respectively, if not utilized.

   The Tax Reform Act of 1986 ("the Act") provides for a limitation on the
annual use of NOL carryforwards (following certain ownership changes, as
defined by the Act) which could significantly limit the Company's ability to
utilize these carryforwards. The Company has experienced various ownership
changes, as defined by the Act, as a result of past financings and the
acquisition by Orchid (see note 11). Accordingly, the Company's ability to
utilize the aforementioned carryforwards may be limited. Additionally, because
U.S. tax laws limit the time during which these carryforwards may be applied
against future taxes, the Company may not be able to take full advantage of
these attributes for Federal income tax purposes.

</TABLE>

   At December 29, 1999, a valuation of allowance of $2,983,347 has been
recognized to fully offset the deferred tax assets as it is more likely than
not that these assets will not be realized. The change in the valuation
allowance in 1998 and 1999 were increases of $504,253 and $678,755,
respectively, related primarily to additional net operating losses incurred by
the Company.

(8) Stockholders' Equity (Deficit)

 Preferred Stock

   The Company is authorized to issue a total of 5,000,000 shares of various
series of preferred stock. The Series A and Series B preferred stocks are
convertible into common stock on a 1-for-1 basis, subject to adjustment for
dilution, are entitled to vote with common stock on the basis of common shares
into which they are convertible, and provide for noncumulative annual dividends
at rates of $.20 and $.26 per share, respectively, when and if declared.

   The Series A and Series B preferred stocks may be redeemed in whole or in
part, at the Company's option, at any time beginning after March 31, 1999 and
January 31, 2003, respectively. The per share redemption price for Series A is
$2.50 plus approximately $.20 for each year outstanding since February 1992.
The per share redemption price for Series B is $3.28 plus approximately $.02
for each month outstanding since February 1996. For both series, the
liquidation value is computed in the same manner as the redemption price. The
Series A and Series B preferred stocks have a liquidation preference over
common stock.

   All shares of the Series A and Series B preferred stocks will automatically
convert to common stock upon the sale of the Company's common stock in a public
offering, subject to certain offering criteria. At December 29, 1999, the
Company has reserved approximately 1,050,000 shares of common stock for
issuance upon conversion of all preferred stock (see note 11).

 Common Stock

   During 1999, a member of GeneScreen's Board of Directors provided
consulting services to the Company in exchange for total consideration of
$289,277, consisting of $93,245 in cash and 47,010 shares of common stock
valued at $196,032.

 Notes Receivable from Stockholders

   Warrants to purchase 50,000 shares of common stock at $2.50 per share were
exercised by two employees in 1996 in exchange for notes receivables totaling
$125,000, which were shown as a reduction of stockholders' equity. During
1997, the Company received payments of $39,683. In 1998, $48,754 was canceled
pursuant to the severance agreement with one of the employees. During 1999,
the remaining outstanding balance of $36,563 was cancelled pursuant to the
settlement agreement with the other employee (see note 10).

(9) Stock Option Plan

   Under the Stock Option Plan (the "Plan"), options to purchase up to 686,667
shares of common stock may be granted to certain key employees and officers of
the Company. Options are exercisable immediately and expire no later than ten
years from the date of grant. The Board may determine the individuals to whom
and the time at which options shall be granted and the number of shares of
common stock covered by each option. The exercise price per share will be
determined by the Board but may not be less than 85% of the fair value of the
common stock on the date of grant. Common stock issued related to the options
is subject to repurchase by GeneScreen upon termination of employment. The
percentage of stock eligible for repurchase will decrease ratably over a
period varying from three to five years from the date of grant. Options for
stock no longer eligible for repurchase are considered fully vested (see note
11).

   The following is a summary of the Plan's activity for the periods shown:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                    December 31, 1998 and December 29, 1999

   Immediately prior to Orchid's acquisition of the Company, all unvested stock
options were subject to accelerated vesting and all outstanding options were
exercised (on a cashless basis) for shares of GeneScreen common stock,
resulting in compensation expense of $964,334, which is reflected in the
consolidated statements of operations for 1999.

   The Company applies the provisions of APB No. 25 and related interpretations
in accounting for its stock option plan. No compensation cost has been
recognized for its stock option plan, since the fair market value of the common
stock at the date of grant was not in excess of the option exercise price. Had
compensation cost for the Company's stock option plan been determined based on
the minimum value of the options at the grant dates consistent with the method
prescribed by SFAS No. 123, the Company's pro forma net loss would have been
$702,693 and $2,170,710 in 1998 and 1999, respectively.

   In the pro forma calculations, the weighted average minimum value of options
granted in 1998 and 1999 was estimated at $.21 and $.23, respectively. The
minimum value of each option grant is estimated on the date of grant using the
minimum value method with the following weighted average assumptions used for
grants in 1998 and 1999: risk free interest rate of 5.1% and 5.6% in 1998 and
1999, respectively; expected lives of six years; no dividend yield; and no
expected volatility (because the Company's stock is not publicly traded).

(10) Commitments and Contingencies

 Leases

   The Company leases its facilities under noncancellable operating leases with
options to renew. Future minimum rental payments as of December 29, 1999, are
as follows:

</TABLE>

   Rent expense in 1998 and 1999 was $295,258 and $322,270, respectively.

 Self-Insurance Reserve

   The Company is self-insured for the risk of loss relating to certain
litigation claims that might arise from the Company's testing results. However,
due to provisions in certain service contracts, the Company is insured for
claims arising from testing performed under the Texas, Ohio and Arizona
contracts. Insurance coverage began in 1995 for testing under the Texas
contract, in 1997 for testing under the Ohio and Arizona contracts and all
other contracts in August 1998. Management estimates future litigation costs
based on historical litigation experience. The accrued litigation reserve for
the self-insured risk at December 31, 1998 and December 29, 1999 was $125,211
and $191,000, respectively.

 Employment Contracts

   Under a 1992 employment contract, the Company was contingently liable to one
individual through December 31, 2001, for minimum payments in the event of
involuntary termination or death of this individual. In 1999, the Company
agreed to a settlement agreement with the employee with a net cost of $327,750,
which

                    December 31, 1998 and December 29, 1999

includes cancellation of a note receivable from the employee for $36,563 plus
accrued interest of $6,056 (see note 8). The settlement is payable in quarterly
installments over three years, the total of which has been recorded at a
discounted amount of $285,131 plus interest of $21,037 (see note 5).

   Until 1998, the Company was contingently liable to another employee under
similar contract conditions. This employee retired effective December 31, 1998,
and the Company agreed to a total severance cost of $550,542, which is payable
as follows: cancellation of a note receivable due from the employee for $48,754
plus accrued interest of $3,863 (see note 8) and payment of the balance of his
contract in quarterly installments over four years, the total of which has been
recorded at a discounted amount of $458,342 plus interest of $39,583 (see note
5).

(11) Acquisition of GeneScreen by Orchid

   On December 30, 1999, Orchid acquired all of the outstanding shares of
common and preferred stock of GeneScreen in exchange for consideration
consisting primarily of 4,000,000 shares of Orchid Series E convertible
preferred stock ("Series E") (see note 9) with a stated value of $4.50 per
share. The Company estimates that approximately $300,000 will be paid in lieu
of issuing Series E shares to satisfy certain regulatory requirements and
eliminate fractional shares. This equates to 65,647 shares of Series E which
will not be issued. Also, as part of the acquisition, the note receivable from
Orchid of $3,547,821 was cancelled. GeneScreen incurred costs totaling $902,490
for fees to outside advisors related to this transaction which are included in
general and administrative expenses in the 1999 consolidated statements of
operations. Amounts included in the accompanying consolidated financial
statements are stated on a historical cost basis and do not reflect any fair
value adjustments which might result from the application of purchase
accounting as a result of the acquisition of the Company by Orchid.

Item 14. Indemnification of Directors and Officers

   Article NINTH of the Registrant's Restated Certificate of Incorporation
provides that a director or officer of the Registrant (a) shall be indemnified
by the Registrant against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement incurred in connection with any litigation
or other legal proceeding (other than an action by or in the right of the
Registrant) brought against him by virtue of his position as a director or
officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful and (b) shall be
indemnified by the Registrant against all expenses (including attorneys' fees)
and amounts paid in settlement incurred in connection with any action by or in
the right of the Registrant brought against him by virtue of his position as a
director or officer of the Registrant if he acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
Registrant, unless a court determines that, despite such adjudication but in
view of all of the circumstances, he is entitled to indemnification of such
expenses. Notwithstanding the foregoing, to the extent that a director or
officer has been successful, on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, he is required to be
indemnified by the Registrant against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his request, provided that he undertakes to repay the amount
advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.

   Indemnification is required to be made unless the Registrant determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought and the Registrant has the
right to participate in such action or assume the defense thereof.

                                      II-1

   Article NINTH of the Registrant's Restated Certificate of Incorporation
further provides that the indemnification provided therein is not exclusive,
and provides that in the event that the Delaware General Corporation Law is
amended to expand the indemnification permitted to directors or officers the
Registrant must indemnify those persons to the fullest extent permitted by such
law as so amended.

   Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if such
person had no reasonable cause to believe his conduct was unlawful; provided
that, in the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such
person shall have been adjudged to be liable to the corporation unless and only
to the extent that the adjudicating court determines that such indemnification
is proper under the circumstances.

   Under Section 8 of the Underwriting Agreement, the Underwriters are
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act. Reference is made to the form of Underwriting Agreement filed
as Exhibit 1 hereto.

Item 17. Undertakings

   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 provisions contained in the Amended and Restated
Certificate of Incorporation of the Registrant and the laws of the State of
Delaware, 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.

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

   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.

Credit Suisse First Boston Corporation
FleetBoston Robertson Stephens Inc.
Salomon Smith Barney Inc.
 As Representatives of the Several Underwriters,
 c/o  Credit Suisse First Boston Corporation,
      Eleven Madison Avenue,
      New York, N.Y. 10010-3629

Dear Sirs:

     1.  Introductory.  Orchid BioSciences, Inc., a Delaware corporation
("Company"), proposes to issue and sell [8,000,000]shares ("Firm Securities") of
its common stock, par value $.001 per share ("Securities") and also proposes to
issue and sell to the Underwriters, at the option of the Underwriters, an
aggregate of not more than [1,200,000] additional shares ("Optional Securities")
of its Securities as set forth below. The Firm Securities and the Optional
Securities are herein collectively called the "Offered Securities". The Company
hereby agrees with the several Underwriters named in Schedule A hereto
("Underwriters") as follows:

     2.  Representations and Warranties of the Company.  The Company represents
and warrants to, and agrees with, the several Underwriters that:

             (a)  A registration statement (No. 333-30774) relating to the
     Offered Securities, including a form of prospectus, has been filed with the
     Securities and Exchange Commission ("Commission") and either (i) has been
     declared effective under the Securities Act of 1933 ("Act") and is not
     proposed to be amended or (ii) is proposed to be amended by amendment or
     post-effective amendment. If such registration statement ("initial
     registration statement") has been declared effective, either (i) an
     additional registration statement ("additional registration statement")
     relating to the Offered Securities may have been filed with the Commission
     pursuant to Rule 462(b) ("Rule 462(b)") under the Act and, if so filed, has
     become effective upon filing pursuant to such Rule and the Offered
     Securities all have been duly registered under the Act pursuant to the
     initial registration statement and, if applicable, the additional
     registration statement or (ii) such an additional registration statement is
     proposed to be filed with the Commission pursuant to Rule 462(b) and will
     become effective upon filing pursuant to such Rule and upon such filing the
     Offered Securities will all have been duly registered under the Act
     pursuant to the initial registration statement and such additional
     registration statement.  If the Company does not propose to amend the
     initial registration statement or if an additional registration statement
     has been filed and the Company does not propose to amend it, and if any
     post-effective amendment to either such registration statement has been
     filed with the Commission prior to the execution and delivery of this
     Agreement, the most recent amendment (if any) to each such registration
     statement has been declared effective by the Commission or has become
     effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Act
     or, in the case of the additional registration statement, Rule 462(b). For
     purposes of this Agreement, "Effective Time" with respect to the initial
     registration statement or, if filed prior to the execution and delivery of
     this Agreement, the additional registration statement means (i) if the
     Company has advised the Representatives that it does not propose to
<PAGE>

     amend such registration statement, the date and time as of which such
     registration statement, or the most recent post-effective amendment thereto
     (if any) filed prior to the execution and delivery of this Agreement, was
     declared effective by the Commission or has become effective upon filing
     pursuant to Rule 462(c), or (ii) if the Company has advised the
     Representatives that it proposes to file an amendment or post-effective
     amendment to such registration statement, the date and time as of which
     such registration statement, as amended by such amendment or post-effective
     amendment, as the case may be, is declared effective by the Commission. If
     an additional registration statement has not been filed prior to the
     execution and delivery of this Agreement but the Company has advised the
     Representatives that it proposes to file one, "Effective Time" with respect
     to such additional registration statement means the date and time as of
     which such registration statement is filed and becomes effective pursuant
     to Rule 462(b). "Effective Date" with respect to the initial registration
     statement or the additional registration statement (if any) means the date
     of the Effective Time thereof. The initial registration statement, as
     amended at its Effective Time, including all information contained in the
     additional registration statement (if any) and deemed to be a part of the
     initial registration statement as of the Effective Time of the additional
     registration statement pursuant to the General Instructions of the Form on
     which it is filed and including all information (if any) deemed to be a
     part of the initial registration statement as of its Effective Time
     pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is hereinafter
     referred to as the "Initial Registration Statement". The additional
     registration statement, as amended at its Effective Time, including the
     contents of the initial registration statement incorporated by reference
     therein and including all information (if any) deemed to be a part of the
     additional registration statement as of its Effective Time pursuant to Rule
     430A(b), is hereinafter referred to as the "Additional Registration
     Statement". The Initial Registration Statement and the Additional
     Registration Statement are herein referred to collectively as the
     "Registration Statements" and individually as a "Registration Statement".
     The form of prospectus relating to the Offered Securities, as first filed
     with the Commission pursuant to and in accordance with Rule 424(b) ("Rule
     424(b)") under the Act or (if no such filing is required) as included in a
     Registration Statement, is hereinafter referred to as the "Prospectus". No
     document has been or will be prepared or distributed in reliance on Rule
     434 under the Act.

             (b)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement: (i) on the Effective
     Date of the Initial Registration Statement, the Initial Registration
     Statement conformed in all respects to the requirements of the Act and the
     rules and regulations of the Commission ("Rules and Regulations") and did
     not include 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 not misleading, (ii) on the Effective Date of the
     Additional Registration Statement (if any), each Registration Statement
     conformed, or will conform, in all respects to the requirements of the Act
     and the Rules and Regulations and did not include, or will not include, any
     untrue statement of a material fact and did not omit, or will not omit, to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading and (iii) on the date of this
     Agreement, the Initial Registration Statement and, if the Effective Time of
     the Additional Registration Statement is prior to the execution and
     delivery of this Agreement, the Additional Registration Statement each
     conforms, and at the time of filing of the Prospectus pursuant to Rule
     424(b) or (if no such filing is required) at the Effective Date of the
     Additional Registration Statement in which the Prospectus is included, each
     Registration Statement and the Prospectus will conform, in all respects to
     the requirements of the Act and the Rules and Regulations, and neither of
     such documents includes, or will include, any untrue statement of a
     material fact or omits, or will omit, to state any material fact required
     to be stated therein or necessary to make the statements therein not
     misleading. If the Effective Time of the Initial Registration Statement is
     subsequent to the execution and delivery of this Agreement, on the
     Effective Date of the Initial Registration Statement, (a) the Initial
     Registration Statement and the Prospectus (i) will conform in all respects
     to the requirements of the Act and the Rules and Regulations, and (ii) will
     not include any untrue statement of a material fact and will not omit to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading, and (b) no Additional Registration
     Statement has been or will be filed. The two preceding sentences do not
     apply to statements in or omissions from a Registration Statement or the
     Prospectus based upon written information furnished to the Company by any
     Underwriter through the Representatives

                                       2
<PAGE>

     specifically for use therein, it being understood and agreed that the only
     such information is that described as such in Section 7(b) hereof.

             (c)  The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of Delaware, with
     power and authority (corporate and other) to own its properties and conduct
     its business as described in the Prospectus; and the Company is duly
     qualified to do business as a foreign corporation in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification, except to the extent
     that the failure to be so qualified or be in good standing would not have a
     material adverse effect on the condition (financial or other), business,
     properties or results of operations of the Company and its subsidiaries,
     taken as a whole (a "Material Adverse Effect").

             (d) Each subsidiary of the Company has been duly incorporated and
     is an existing corporation in good standing under the laws of the
     jurisdiction of its incorporation, with power and authority (corporate and
     other) to own its properties and conduct its business as described in the
     Prospectus; and each subsidiary of the Company is duly qualified to do
     business as a foreign corporation in good standing in all other
     jurisdictions in which its ownership or lease of property or the conduct of
     its business requires such qualification, except where the failure to be so
     qualified would not have a Material Adverse Effect; all of the issued and
     outstanding capital stock of each subsidiary of the Company has been duly
     authorized and validly issued and is fully paid and nonassessable; and all
     of the outstanding capital stock of each subsidiary is owned by the
     Company, directly or through subsidiaries, free from liens, encumbrances
     and defects.

             (e)  The Offered Securities and all other outstanding shares of
     capital stock of the Company have been duly authorized; all outstanding
     shares of capital stock of the Company are, and, when the Offered
     Securities have been delivered and paid for in accordance with this
     Agreement on each Closing Date (as defined below), such Offered Securities
     will have been, validly issued, fully paid and nonassessable and will
     conform to the description thereof contained in the Prospectus; and, except
     as disclosed in the Prospectus, the stockholders of the Company have no
     preemptive rights with respect to the Securities.

             (f) Except as disclosed in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person that would
     give rise to a valid claim against the Company or any Underwriter for a
     brokerage commission, finder's fee or other like payment in connection with
     this offering of the Offered Securities.

             (g)  Except as described in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person granting
     such person the right to require the Company to file a registration
     statement under the Act with respect to any securities of the Company owned
     or to be owned by such person or to require the Company to include such
     securities in the Offered Securities registered pursuant to the
     Registration Statement.

             (h)  The Offered Securities have been approved for listing on the
     Nasdaq Stock Market's National Market, subject to notice of issuance.

             (i) No consent, approval, authorization, or order of, or filing
     with, any governmental agency or body or any court is required for the
     consummation of the transactions contemplated by this Agreement in
     connection with the issuance and sale of the Offered Securities by the
     Company, except such as have been obtained and made under the Act and
     except as may be required under state securities laws.

             (j) The execution, delivery and performance of this Agreement, and
     the issuance and sale of the Offered Securities will not result in a breach
     or violation of any of the terms and provisions of, or constitute a default
     under, any statute, any rule, regulation or order of any governmental
     agency or body or any court, domestic or foreign, having jurisdiction over
     the Company or any subsidiary of the Company or

                                       3
<PAGE>

     any of their properties, or any agreement or instrument to which the
     Company or any such subsidiary is a party or by which the Company or any
     such subsidiary is bound or to which any of the properties of the Company
     or any such subsidiary is subject, or the charter or by-laws of the Company
     or any such subsidiary, except as may be required under state securities
     laws in connection with the offer and sale of the Offered Securities, and
     the Company has full power and authority to authorize, issue and sell the
     Offered Securities as contemplated by this Agreement.

             (k) This Agreement has been duly authorized, executed and delivered
     by the Company.

             (l) Except as disclosed in the Prospectus, the Company and its
     subsidiaries have good and marketable title to all real properties and all
     other properties and assets owned by them, in each case free from liens,
     encumbrances and defects that would materially affect the value thereof or
     materially interfere with the use made or to be made thereof by them; and
     except as disclosed in the Prospectus, the Company and its subsidiaries
     hold any leased real or personal property under valid and enforceable
     leases with no exceptions that would materially interfere with the use made
     or to be made thereof by them.

             (m) The Company and its subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now operated by them and have not
     received any notice of proceedings relating to the revocation or
     modification of any such certificate, authority or permit that, if
     determined adversely to the Company or any of its subsidiaries, would
     individually or in the aggregate have a Material Adverse Effect.

             (n) No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Company, is imminent that
     would be reasonable likely to have a Material Adverse Effect.

             (o) The Company and its subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

             (p) Except as disclosed in the Prospectus, neither the Company nor
     any of its subsidiaries is in violation of any statute, any rule,
     regulation, decision or order of any governmental agency or body or any
     court, domestic or foreign, relating to the use, disposal or release of
     hazardous or toxic substances or relating to the protection or restoration
     of the environment or human exposure to hazardous or toxic substances
     (collectively, "environmental laws"), owns or operates any real property
     contaminated with any substance that is subject to any environmental laws,
     is liable for any off-site disposal or contamination pursuant to any
     environmental laws, or is subject to any claim relating to any
     environmental laws, which violation, contamination, liability or claim
     would individually or in the aggregate have a Material Adverse Effect; and
     the Company is not aware of any pending investigation which might lead to
     such a claim.

             (q) Except as disclosed in the Prospectus, there are no pending
     actions, suits or proceedings against or affecting the Company, any of its
     subsidiaries or any of their respective properties that, if determined
     adversely to the Company or any of its subsidiaries, would individually or
     in the aggregate have a Material Adverse Effect, or would materially and
     adversely affect the ability of the Company to perform its obligations
     under this Agreement, or which are otherwise material in the context of the
     sale of the Offered Securities; and no such actions, suits or proceedings,
     to the Company's knowledge, are threatened or contemplated.

                                       4
<PAGE>

             (r) There are no contracts or documents to which the Company is a
     party which are of a character required to be filed as exhibits to the
     Registration Statement which are not filed as required;

             (s) The financial statements included in each Registration
     Statement and the Prospectus (taken together with the related notes and
     schedules thereto) present fairly the financial position of the Company and
     its consolidated subsidiaries as of the dates shown and their results of
     operations and cash flows for the periods shown, and such financial
     statements have been prepared in conformity with the generally accepted
     accounting principles in the United States ("GAAP") applied on a consistent
     basis; the schedules included in each Registration Statement present fairly
     the information required to be stated therein; and the assumptions used in
     preparing the pro forma financial statements included in each Registration
     Statement and the Prospectus provide a reasonable basis for presenting the
     significant effects directly attributable to the transactions or events
     described therein, the related pro forma adjustments give appropriate
     effect to those assumptions, and the pro forma columns therein reflect the
     proper application of those adjustments to the corresponding historical
     financial statement amounts.

             (t) Except as disclosed in the Prospectus, since the date of the
     latest audited financial statements included in the Prospectus there has
     been no material adverse change, nor any development or event involving a
     prospective material adverse change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     subsidiaries taken as a whole, and, except as disclosed in or contemplated
     by the Prospectus, there has been no dividend or distribution of any kind
     declared, paid or made by the Company on any class of its capital stock.

             (u) The Company is not and, after giving effect to the offering and
     sale of the Offered Securities and the application of the proceeds thereof
     as described in the Prospectus, will not be an "investment company" as
     defined in the Investment Company Act of 1940.

     3.  Purchase, Sale and Delivery of Offered Securities.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $           per share, the respective
numbers of shares of Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

     The Company will deliver the Firm Securities to the Representatives for the
accounts of the Underwriters through the facilities of the Depository Trust
Company against payment of the purchase price in Federal (same day) funds by
official bank check or checks or wire transfer to an account at a bank
acceptable to Credit Suisse First Boston Corporation ("CSFBC").  The Closing of
the sale of the Firm Securities will take place at the offices of Willkie Farr &
Gallagher, 787 Seventh Avenue, New York, New York, at 10:00 A.M., New York time,
on _________, 2000, or at such other time not later than seven full business
days thereafter as CSFBC and the Company determine, such time being herein
referred to as the "First Closing Date". For purposes of Rule 15c6-1 under the
Securities Exchange Act of 1934, the First Closing Date (if later than the
otherwise applicable settlement date) shall be the settlement date for payment
of funds and delivery of securities for all the Offered Securities sold pursuant
to the offering. The certificates for the Firm Securities so to be delivered
will be in definitive form, in such denominations and registered in such names
as CSFBC requests and will be made available for inspection by the
Representatives at least 24 hours prior to the First Closing Date.

     In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. The Company
agrees to sell to the Underwriters number of shares of Optional Securities
specified in such notice and the Underwriters agree, severally and not jointly,
to purchase such Optional Securities. Such Optional Securities shall be
purchased for the account of each Underwriter in the same proportion as the
number of shares of Firm Securities set forth opposite such Underwriter's name
bears to the total number of shares of Firm Securities (subject to adjustment by
CSFBC to eliminate fractions) and may be purchased by the Underwriters only for
the purpose of covering over-allotments

                                       5
<PAGE>

made in connection with the sale of the Firm Securities. No Optional Securities
shall be sold or delivered unless the Firm Securities previously have been, or
simultaneously are, sold and delivered. The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CSFBC to the Company.

     Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters through the
facilities of the Depository Trust Company against payment of the purchase price
therefor in Federal (same day) funds by official bank check or checks or wire
transfer to an account at a bank acceptable to CSFBC. Each closing for the sale
of Optional Securities will take place at the offices of Willkie Farr &
Gallagher.   The certificates for the Optional Securities being purchased on
each Optional Closing Date will be in definitive form, in such denominations and
registered in such names as CSFBC requests upon reasonable notice prior to such
Optional Closing Date and will be made available for inspection by the
Representatives at a reasonable time in advance of such Optional Closing Date.

     4.  Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

     5.  Certain Agreements of the Company. The Company agrees with the several
Underwriters that:

          (a)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, the Company will
     file the Prospectus with the Commission pursuant to and in accordance with
     subparagraph (1) (or, if applicable and if consented to by CSFBC,
     subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the
     second business day following the execution and delivery of this Agreement
     or (B) the fifteenth business day after the Effective Date of the Initial
     Registration Statement.

          The Company will advise CSFBC promptly of any such filing pursuant to
     Rule 424(b). If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement and an additional
     registration statement is necessary to register a portion of the Offered
     Securities under the Act but the Effective Time thereof has not occurred as
     of such execution and delivery, the Company will file the additional
     registration statement or, if filed, will file a post-effective amendment
     thereto with the Commission pursuant to and in accordance with Rule 462(b)
     on or prior to 10:00 P.M., New York time, on the date of this Agreement or,
     if earlier, on or prior to the time the Prospectus is printed and
     distributed to any Underwriter, or will make such filing at such later date
     as shall have been consented to by CSFBC.

             (b)  The Company will advise CSFBC promptly of any proposal to
     amend or supplement the initial or any additional registration statement as
     filed or the related prospectus or the Initial Registration Statement, the
     Additional Registration Statement (if any) or the Prospectus and will not
     effect such amendment or supplementation without CSFBC's consent; and the
     Company will also advise CSFBC promptly of the effectiveness of each
     Registration Statement (if its Effective Time is subsequent to the
     execution and delivery of this Agreement) and of any amendment or
     supplementation of a Registration Statement or the Prospectus and of the
     institution by the Commission of any stop order proceedings in respect of a
     Registration Statement and will use its best efforts to prevent the
     issuance of any such stop order and to obtain as soon as possible its
     lifting, if issued.

             (c)  If, at any time when a prospectus relating to the Offered
     Securities is required to be delivered under the Act in connection with
     sales by any Underwriter or dealer, any event occurs as a result of which
     the Prospectus as then amended or supplemented would include an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it is necessary at any time to
     amend the

                                       6
<PAGE>

     Prospectus to comply with the Act, the Company will promptly notify CSFBC
     of such event and will promptly prepare and file with the Commission, at
     its own expense, an amendment or supplement which will correct such
     statement or omission or an amendment which will effect such compliance.
     Neither CSFBC's consent to, nor the Underwriters' delivery of, any such
     amendment or supplement shall constitute a waiver of any of the conditions
     set forth in Section 6.

             (d)  As soon as practicable, but not later than the Availability
     Date (as defined below), the Company will make generally available to its
     securityholders an earnings statement covering a period of at least 12
     months beginning after the Effective Date of the Initial Registration
     Statement (or, if later, the Effective Date of the Additional Registration
     Statement) which will satisfy the provisions of Section 11(a) of the Act.
     For the purpose of the preceding sentence, "Availability Date" means the
     45th day after the end of the fourth fiscal quarter following the fiscal
     quarter that includes such Effective Date, except that, if such fourth
     fiscal quarter is the last quarter of the Company's fiscal year,
     "Availability Date" means the 90th day after the end of such fourth fiscal
     quarter.

             (e)  The Company will furnish to the Representatives copies of each
     Registration Statement (four of which will be signed and will include all
     exhibits), each related preliminary prospectus, and, so long as a
     prospectus relating to the Offered Securities is required to be delivered
     under the Act in connection with sales by any Underwriter or dealer, the
     Prospectus and all amendments and supplements to such documents, in each
     case in such quantities as CSFBC requests. The Prospectus shall be so
     furnished on or prior to 3:00 P.M., New York time, on the business day
     following the later of the execution and delivery of this Agreement or the
     Effective Time of the Initial Registration Statement. All other documents
     shall be so furnished as soon as available. The Company will pay the
     expenses of printing and distributing to the Underwriters all such
     documents.

             (f)  The Company will arrange for the qualification of the Offered
     Securities for sale under the laws of such jurisdictions as CSFBC
     designates and will continue such qualifications in effect so long as
     required for the distribution.

             (g)  During the period of five (5) years hereafter, the Company
     will furnish to the Representatives and, upon request, to each of the other
     Underwriters, as soon as practicable after the end of each fiscal year, a
     copy of its annual report to stockholders for such year; and the Company
     will furnish to the Representatives (i) as soon as available, a copy of
     each report and any definitive proxy statement of the Company filed with
     the Commission under the Securities Exchange Act of 1934 or mailed to
     stockholders, and (ii) from time to time, such other information concerning
     the Company as CSFBC may reasonably request.

             (h)  The Company will pay all expenses incident to the performance
     of its obligations under this Agreement, for any filing fees and other
     expenses (including fees and disbursements of counsel) incurred in
     connection with qualification of the Offered Securities for sale under the
     laws of such jurisdictions as CSFBC designates and the printing of
     memoranda relating thereto, for the filing fee incident to, and the
     reasonable fees and disbursements of counsel to the Underwriters in
     connection with, the review by the National Association of Securities
     Dealers, Inc. of the Offered Securities, for any travel expenses of the
     Company's officers and employees and any other expenses of the Company in
     connection with attending or hosting meetings with prospective purchasers
     of the Offered Securities and for expenses incurred in distributing
     preliminary prospectuses and the Prospectus (including any amendments and
     supplements thereto) to the Underwriters.

             (i)  For a period of 180 days after the date of the initial public
     offering of the Offered Securities, the Company will not offer, sell,
     contract to sell, pledge or otherwise dispose of, directly or indirectly,
     or file with the Commission a registration statement under the Act relating
     to, any additional shares of its Securities or securities convertible into
     or exchangeable or exercisable for any shares of its Securities, or
     publicly disclose the intention to make any such offer, sale, pledge,
     disposition or filing, without the prior written consent of CSFBC; provided
                                                                        --------
     that the foregoing shall not restrict the Company's
     ----

<PAGE>

     ability to (x) issue Securities pursuant to the conversion or exchange of
     convertible or exchangeable securities or the exercise of warrants or
     options, in each case outstanding on the date hereof, (y) grant employee
     stock options pursuant to the terms of a plan in effect on the date hereof,
     or (z) issue Securities pursuant to the exercise of employee stock options
     issued in compliance with clause (y) above.

     6.  Conditions of the Obligations of the Underwriters. The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

             (a)  The Representatives shall have received a letter, dated the
     date of delivery thereof (which, if the Effective Time of the Initial
     Registration Statement is prior to the execution and delivery of this
     Agreement, shall be on or prior to the date of this Agreement or, if the
     Effective Time of the Initial Registration Statement is subsequent to the
     execution and delivery of this Agreement, shall be prior to the filing of
     the amendment or post-effective amendment to the registration statement to
     be filed shortly prior to such Effective Time), of KPMG LLC confirming that
     they are independent public accountants within the meaning of the Act and
     the applicable published Rules and Regulations thereunder and stating to
     the effect that:

                    (i) in their opinion the financial statements and schedules
          examined by them and included in the Registration Statements comply as
          to form in all material respects with the applicable accounting
          requirements of the Act and the related published Rules and
          Regulations;

                    (ii) on the basis of a reading of the latest available
          interim financial statements of the Company, inquiries of officials of
          the Company who have responsibility for financial and accounting
          matters and other specified procedures, nothing came to their
          attention that caused them to believe that:

                         (A) at the date of the latest available balance sheet
               read by such accountants, or at a subsequent specified date not
               more than three business days prior to the date of this
               Agreement, there was any change in the capital stock or any
               increase in short-term indebtedness or long-term debt of the
               Company and its consolidated subsidiaries or, at the date of the
               latest available balance sheet read by such accountants, there
               was any decrease in consolidated net assets, as compared with
               amounts shown on the latest balance sheet included in the
               Prospectus; or

                         (B) for the period from the closing date of the latest
               income statement included in the Prospectus to the closing date
               of the latest available income statement read by such accountants
               there were any decreases, as compared with the corresponding
               period of the previous year and with the period of corresponding
               length ended the date of the latest income statement included in
               the Prospectus, in consolidated net sales, or net operating
               income, or in the total or per share amounts of consolidated  net
               income,

          except in all cases set forth in clauses (A) and (B) above for
          changes, increases or decreases which the Prospectus discloses have
          occurred or may occur or which are described in such letter; and

                    (iii) they have compared specified dollar amounts (or
          percentages derived from such dollar amounts) and other financial
          information contained in the Registration Statements (in each case to
          the extent that such dollar amounts, percentages and other financial
          information are derived from the general accounting records of the
          Company and its subsidiaries subject to the internal controls of the
          Company's accounting system or are derived directly from

                                       8
<PAGE>

          such records by analysis or computation) with the results obtained
          from inquiries, a reading of such general accounting records and other
          procedures specified in such letter and have found such dollar
          amounts, percentages and other financial information to be in
          agreement with such results, except as otherwise specified in such
          letter.

          For purposes of this subsection, (i) if the Effective Time of the
     Initial Registration Statement is subsequent to the execution and delivery
     of this Agreement, "Registration Statements" shall mean the initial
     registration statement as proposed to be amended by the amendment or post-
     effective amendment to be filed shortly prior to its Effective Time, (ii)
     if the Effective Time of the Initial Registration Statement is prior to the
     execution and delivery of this Agreement but the Effective Time of the
     Additional Registration is subsequent to such execution and delivery,
     "Registration Statements" shall mean the Initial Registration Statement and
     the additional registration statement as proposed to be filed or as
     proposed to be amended by the post-effective amendment to be filed shortly
     prior to its Effective Time, and (iii) "Prospectus" shall mean the
     prospectus included in the Registration Statements.

               (b) The Representatives shall have received from KPMG LLC an
     examination report, dated the date of delivery thereof (which, if the
     Effective Time of the Initial Registration Statement is prior to the
     execution and delivery of this Agreement, shall be on or prior to the date
     of this Agreement or, if the Effective Time of the Initial Registration
     Statement is subsequent to the execution and delivery of this Agreement,
     shall be prior to the filing of the amendment or post-effective amendment
     to the registration statement to be filed shortly prior to such Effective
     Time), on the pro forma financial information contained in the Registration
     Statements, which report shall be in accordance with AICPA Statement on
     Standards for Attestation Engagements No. 1, "Reporting on Pro Forma
     Financial Statements."

               (c)  If the Effective Time of the Initial Registration Statement
     is not prior to the execution and delivery of this Agreement, such
     Effective Time shall have occurred not later than 10:00 P.M., New York
     time, on the date of this Agreement or such later date as shall have been
     consented to by CSFBC. If the Effective Time of the Additional Registration
     Statement (if any) is not prior to the execution and delivery of this
     Agreement, such Effective Time shall have occurred not later than 10:00
     P.M., New York time, on the date of this Agreement or, if earlier, the time
     the Prospectus is printed and distributed to any Underwriter, or shall have
     occurred at such later date as shall have been consented to by CSFBC.  If
     the Effective Time of the Initial Registration Statement is prior to the
     execution and delivery of this Agreement, the Prospectus shall have been
     filed with the Commission in accordance with the Rules and Regulations and
     Section 5(a) of this Agreement. Prior to such Closing Date, no stop order
     suspending the effectiveness of a Registration Statement shall have been
     issued and no proceedings for that purpose shall have been instituted or,
     to the knowledge of the Company or the Representatives, shall be
     contemplated by the Commission.

               (d)  Subsequent to the execution and delivery of this Agreement,
     there shall not have occurred (i) any change, or any development or event
     involving a prospective change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     subsidiaries taken as one enterprise which, in the judgment of a majority
     in interest of the Underwriters including the Representatives, is material
     and adverse and makes it impractical or inadvisable to proceed with
     completion of the public offering or the sale of and payment for the
     Offered Securities; (ii) any downgrading in the rating of any debt
     securities of the Company by any "nationally recognized statistical rating
     organization" (as defined for purposes of Rule 436(g) under the Act), or
     any public announcement that any such organization has under surveillance
     or review its rating of any debt securities of the Company (other than an
     announcement with positive implications of a possible upgrading, and no
     implication of a possible downgrading, of such rating); (iii) any material
     suspension or material limitation of trading in securities generally on the
     New York Stock Exchange, or any setting of minimum prices for trading on
     such exchange, or any suspension of trading of any securities of the
     Company on any exchange or in the over-the-counter market; (iv) any banking
     moratorium declared by U.S. Federal or New York authorities; or (v) any
     outbreak or escalation of major hostilities in which the United States is
     involved, any declaration of war by Congress or any other substantial
     national or international calamity or emergency if, in the

                                       9
<PAGE>

     judgment of a majority in interest of the Underwriters including the
     Representatives, the effect of any such outbreak, escalation, declaration,
     calamity or emergency makes it impractical or inadvisable to proceed with
     completion of the public offering or the sale of and payment for the
     Offered Securities.

               (e)  The Representatives shall have received an opinion, dated
     such Closing Date, of Mintz, Levin, Cohn, Ferris, Glovsky, and Popeo, P.C.,
     counsel for the Company, to the effect that:

                    (i)  The Company has been duly incorporated and is an
          existing corporation in good standing under the laws of the State of
          Delaware, with power and authority (corporate and other) to own its
          properties and conduct its business as described in the Prospectus;
          and the Company is duly qualified to do business as a foreign
          corporation in good standing in New Jersey and Maryland, which are the
          only jurisdictions in which the Company maintains and office or leases
          property;

                    (ii) Each subsidiary of the Company has been duly
          incorporated and is an existing corporation in good standing under the
          laws of the jurisdiction of its incorporation, with power and
          authority (corporate and other) to own its properties and conduct its
          business as described in the Prospectus; and each subsidiary of the
          Company is duly qualified to do business as a foreign corporation in
          good standing in Texas, Ohio, California, Maryland, Illinois and
          Mississippi, which are the only jurisdictions in which a subsidiary of
          the Company maintains an office or leases property;

                    (iii)  The Offered Securities delivered on such Closing Date
          and all other outstanding shares of the Common Stock of the Company
          have been duly authorized and validly issued, are fully paid and
          nonassessable and conform to the description thereof contained in the
          Prospectus under the caption "Description of Capital Stock"; and,
          except as disclosed in the Prospectus, the stockholders of the Company
          have no preemptive rights with respect to the Securities under the
          Delaware General Corporation Law, the Company's Certificate of
          Incorporation or Bylaws or, to such counsel's knowledge, any agreement
          to which the Company is a party;

                    (iv) Except as disclosed in the Prospectus, to such
          counsel's knowledge, there are no contracts, agreements or
          understandings between the Company and any person granting such person
          the right to require the Company to file a registration statement
          under the Act with respect to any securities of the Company owned or
          to be owned by such person or to require the Company to include such
          securities in the securities registered pursuant to the Registration
          Statement;

                    (v)  The Company is not and, after giving effect to the
          offering and sale of the Offered Securities and the application of the
          proceeds thereof as described in the Prospectus, will not be an
          "investment company" as defined in the Investment Company Act of 1940.

                    (vi)  No consent, approval, authorization or order of, or
          filing with, any governmental agency or body or any court is required
          for the consummation of the transactions contemplated by this
          Agreement in connection with the issuance or sale of the Offered
          Securities by the Company, except such as have been obtained and made
          under the Act and such as may be required under state securities laws
          (with respect to which, such counsel need express no opinion);

                    (vii)  The execution, delivery and performance of this
          Agreement and the issuance and sale of the Offered Securities will not
          result in a breach or violation of any of the terms and provisions of,
          or constitute a default under, (a) any statute, any rule or
          regulation, (b) any order of any governmental agency or body or any
          court having jurisdiction over the Company

                                       10
<PAGE>

          or any subsidiary of the Company or any of their properties of which
          such counsel has knowledge, (c) any agreement or instrument to which
          the Company or any such subsidiary is a party or by which the Company
          or any such subsidiary is bound or to which any of the properties of
          the Company or any such subsidiary is subject and which is listed as
          an exhibit to the Registration Statement or of which such counsel has
          knowledge, or (d) the charter or by-laws of the Company or any such
          subsidiary, and the Company has full power and authority to authorize,
          issue and sell the Offered Securities as contemplated by this
          Agreement;

                    (viii)  The Initial Registration Statement was declared
          effective under the Act as of the date and time specified in such
          opinion, the Additional Registration Statement (if any) was filed and
          became effective under the Act as of the date and time (if
          determinable) specified in such opinion, the Prospectus either was
          filed with the Commission pursuant to the subparagraph of Rule 424(b)
          specified in such opinion on the date specified therein or was
          included in the Initial Registration Statement or the Additional
          Registration Statement (as the case may be), and, to the best of the
          knowledge of such counsel, no stop order suspending the effectiveness
          of a Registration Statement or any part thereof has been issued and no
          proceedings for that purpose have been instituted or are pending or
          threatened by the Commission;

                    (ix) Each Registration Statement and the Prospectus (except
          as to the financial statements and schedules and other financial data
          and statistical data derived therefrom as to which such counsel need
          express no opinion), and each amendment or supplement thereto, as of
          their respective effective or issue dates, complied as to form in all
          material respects with the requirements of the Act and the Rules and
          Regulations;

                    (x) To the knowledge of such counsel, but without inquiring
          into the dockets of any court, commission, administrative agency or
          other government body, there are no legal or governmental proceedings
          pending or threatened to which the Company or any of its subsidiaries
          is a party which are required to be disclosed in the Registration
          Statement which are not disclosed as required, nor to such counsel's
          knowledge are there contracts or documents to which the Company is a
          party which are of a character required to be filed as exhibits to the
          Registration Statement which are not filed as required;

                    (xi) The statements set forth under the headings "Management
          - Stock Incentive Plans," "Transactions with Executive Officers,
          Directors and Five Percent Stockholders," "Description of Capital
          Stock," and "Shares Eligible for Future Sale" in the Prospectus,
          insofar as such statements purport to summarize legal matters,
          documents or proceedings referred to therein, provide a fair summary
          in all material respects of such legal matters, documents or
          proceedings to the extent required under the Act and the Rules and
          Regulations thereunder;

                    (xii) This Agreement has been duly authorized, executed and
          delivered by the Company.

                    (xiii) In addition to the matters set forth above, counsel
          rendering the foregoing opinion shall also include a statement to the
          effect that while such counsel have not independently verified and
          accordingly are not passing upon and do not assume responsibility for
          the accuracy, completeness or fairness of the statements contained in
          the Registration Statement, based upon its participation in
          conferences with officers and representatives of the Company, counsel
          for the underwriters and the independent public accountants of the
          Company, nothing has come to such counsel's attention which has caused
          such counsel to believe that any part of the Registration Statement or
          any amendment thereto (except as to the financial statements and
          schedules and other financial data and statistical data derived
          therefrom as to which such counsel need express no opinion) on the
          date it became effective under the Act, contained an untrue statement
          of a material fact or omitted to state a material fact required to be
          stated therein or

                                       11
<PAGE>

          necessary to make the statement therein not misleading, or that the
          Prospectus or any amendment or supplement thereto (except as to the
          financial statements and schedules and other financial data and
          statistical data derived therefrom as to which such counsel need
          express no opinion), as of its date or the date such statement is
          delivered contained an untrue statement of a material fact or omitted
          or omits to state a material fact necessary in order to make the
          statements therein, in light of the circumstances under which they
          were made, not misleading.

               (f) The Representatives shall have received an opinion, dated
     such Closing Date, of Kalow, Springut & Bressler LLP, patent counsel for
     the Company, and in a form satisfactory to Willkie Farr & Gallagher,
     counsel for the Underwriters, stating that:

                    (i) with respect to each element of such opinion, it is
          understood and acknowledged by the Underwriters:  (a) that Kalow
          Springut & Bressler LLP has been retained as counsel for the Company
          for less than one year and did not prosecute any of the Company's
          applications for patent or trademark registration until recently; (b)
          that firms other than Kalow Springut & Bressler LLP have in the past
          had and at present have responsibility for substantial portions of the
          Company's intellectual-property portfolio; (c) that, unless stated
          otherwise, the conclusions expressed in such opinion are based on a
          review of files transferred to Kalow Springut & Bressler LLP by
          predecessor counsel and not on a review of official files of the
          United States Patent and Trademark Office or of foreign patent or
          trademark offices, which may differ from the transferred files; and
          (d) that Kalow Springut & Bressler LLP and/or members of the firm own
          stock in the Company or have been granted stock options by the
          Company;

                    (ii) based upon such counsel's (a) inquiry of the Company's
          representatives responsible for patent and trademark matters, (b) such
          counsel's review of the chain of title records obtained from the
          United States Patent and Trademark Office ("USPTO") for the United
          States patents, patent applications, trademark registrations, and
          applications for trademark registration, and (c) inquiries to foreign
          associates regarding the status of filing of any assignment to the
          Company in a foreign jurisdiction as required by that jurisdiction
          with regard to foreign patents, patent applications, trademark
          registrations and applications for trademark registrations, but
          without inquiring into any UCC security interest records, (i) to such
          counsel's knowledge, the patent and pending patent applications that
          are listed on Schedule A to the opinion ("Patents") and the trademark
          registrations and pending applications for trademark registration that
          are listed on Schedule B to the opinion ("Trademarks") have been
          validly assigned to the Company or all inventors on such Patents are
          under an obligation to assign all of their rights in such Patents to
          the Company, and (ii) except as provided in Schedules A and B, the
          Company is listed as the sole holder of record of each of the Patents
          and Trademarks.  Except as provided in Schedule A and B, such counsel
          knows of no claim of a third party to any ownership interest in, or to
          any lien with respect to, any of the Patents or Trademarks, and knows
          of no nonjoined inventorship interest in any of the Patents who is not
          under an obligation to assign his or her interest in the invention to
          the Company.  To such counsel's knowledge and based upon inquiry of
          the Company's representatives responsible for patent and trademark
          matters, but without inquiring into the dockets of any court,
          commission, administrative agency, or other government body and except
          as provided on Schedule C to the opinion, no claim, action, or suit or
          proceeding is presently pending or threatened against the Company
          relating to the potential infringement of, or conflict with, any
          patents of others.  Except as provided on Schedules A and B, none of
          the Patents or Trademarks has been abandoned, lapsed, or been finally
          determined to be unpatentable, invalid, unregisterable, or
          unenforceable by any court or administrative tribunal having
          jurisdiction over any such matter;

                    (iii) to such counsel's knowledge, the requirements of 37
          CFR Section 1.56 (1999) have been or will be met for each of the
          United States Patents and no fraud or other inequitable conduct has
          been practiced or attempted with respect to United States Trademarks.
          No fact that has not been disclosed or will not be disclosed to the
          USPTO has come to such counsel's

                                       12
<PAGE>

          attention that causes such counsel to question the patentability,
          registrability, validity or enforceability of the Patents or of any of
          the pending applications for United States Patents or pending
          applications for United States Trademarks. Except as provided in
          Schedule C to the opinion ("Schedule C"), such counsel knows of no
          pending or threatened action, suit, proceeding or claim by others
          challenging the validity or enforceability of any claim of an issued
          Patent or of a Trademark;

                    (iv) to such counsel's knowledge and based upon inquiry of
          the Company's representatives responsible for patent and trademark
          matters, but without inquiring into the dockets of any court,
          commission, administrative agency, or other government body, and
          except as provided in Schedule C to the opinion, there are no
          threatened interference, opposition, public use, reexamination,
          reissue, or protest proceedings with respect to any Patent, or any
          pending or threatened opposition, cancellation, interference, or
          concurrent use proceeding with respect to any Trademark, in the United
          States or in a foreign jurisdiction;

                    (v) based upon inquiry of the Company's representatives
          responsible for patent and trademark matters, the patents, pending
          patent applications, trademark registrations, and applications for
          trademark registration listed on Schedule D to the opinion have been
          licensed to the Company;

                    (vi) no facts have come to such counsel's attention which
          cause such counsel to believe that the statements in the Prospectus
          relating to patent and trademark matters under the caption "If we are
          unable to protect our proprietary methods and technologies, we may not
          be able to operate our business profitably" in "Risk Factors" and the
          caption "Intellectual Property" in "Business" result in the Prospectus
          containing an untrue or misleading statement of material fact, or
          omitting a material fact necessary to make the statements therein not
          misleading.

               (g)  The Representatives shall have received from Willkie Farr &
     Gallagher, counsel for the Underwriters, such opinion or opinions, dated
     such Closing Date, with respect to the incorporation of the Company, the
     validity of the Offered Securities delivered on such Closing Date, the
     Registration Statements, the Prospectus and other related matters as the
     Representatives may require, and the Company shall have furnished to such
     counsel such documents as they request for the purpose of enabling them to
     pass upon such matters.

               (h)  The Representatives shall have received a certificate, dated
     such Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that: the representations and warranties of the Company in this Agreement
     are true and correct; the Company has complied with all agreements and
     satisfied all conditions on its part to be performed or satisfied hereunder
     at or prior to such Closing Date; no stop order suspending the
     effectiveness of any Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are contemplated by
     the Commission; the Additional Registration Statement (if any) satisfying
     the requirements of subparagraphs (1) and (3) of Rule 462(b) was filed
     pursuant to Rule 462(b), including payment of the applicable filing fee in
     accordance with Rule 111(a) or (b) under the Act, prior to the time the
     Prospectus was printed and distributed to any Underwriter; and, subsequent
     to the date of the most recent financial statements in the Prospectus,
     there has been no material adverse change, nor any development or event
     involving a prospective material adverse change, in the condition
     (financial or other), business, properties or results of operations of the
     Company and its subsidiaries taken as a whole except as set forth in or
     contemplated by the Prospectus or as described in such certificate.

               (i)  The Representatives shall have received a letter, dated such
     Closing Date, of KPMG LLC which meets the requirements of subsections (a)
     and (b) of this Section, except that the specified date referred to in such
     subsections will be a date not more than three days prior to such Closing
     Date for the purposes of this subsection.

                                       13
<PAGE>

               (j)  On or prior to the date of this Agreement, the
     Representatives shall have received lockup letters from each of the
     executive officers and directors of the Company and holders of __% or more
     of the Company's outstanding Common Stock, on an as-converted or as-
     exercised basis in the case of holders of securities convertible into, or
     exercisable for, Common Stock.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request.  CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder,
whether in respect of an Optional Closing Date or otherwise.

     7.  Indemnification and Contribution.  (a)  The Company will indemnify and
hold harmless each Underwriter, its partners, directors and officers and each
person, if any, who controls such Underwriter within the meaning of Section 15
of the Act, against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the 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,
the Prospectus, or any amendment or supplement thereto, or any related
preliminary prospectus, 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 Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company will not be liable in any such case 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 in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
information described as such in subsection (b) below; and provided, further,
that with respect to any untrue statement or alleged untrue statement in or
omission or alleged omission from any preliminary prospectus the indemnity
agreement contained in this subsection (a) shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages or
liabilities purchased the Offered Securities concerned, to the extent that a
prospectus relating to such Offered Securities was required to be delivered by
such Underwriter under the Act in connection with such purchase and any such
loss, claim, damage or liability of such Underwriter results from the fact that
there was not sent or given to such person, at or prior to the written
confirmation of the sale of such Offered Securities to such person, a copy of
the Prospectus if the Company had previously furnished copies thereof to such
Underwriter.

     (b)  Each Underwriter will severally and not jointly indemnify and hold
harmless the Company, its directors and officers and each person, if any who
controls the Company within the meaning of Section 15 of the Act, against any
losses, claims, damages or liabilities to which the Company may become subject,
under the 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, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished to the
Company by such Underwriter through the Representatives specifically for use
therein, and will reimburse any legal or other expenses reasonably incurred by
the Company in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred, it being understood
and agreed that the only such information furnished by any Underwriter consists
of the following information in the Prospectus furnished on behalf of each
Underwriter:  the concession and reallowance figures appearing in the fourth
(4th) paragraph under the caption "Underwriting"; and the information contained
in the eleventh (11th) paragraph under the caption "Underwriting".

     (c)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party

                                       14
<PAGE>

under (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above. In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement (i) includes an unconditional release
of such indemnified party from all liability on any claims that are the subject
matter of such action and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act by or on behalf of an
indemnified party.

     (d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the Securities
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Underwriters on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by the Underwriters.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding the provisions of this subsection (d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this subsection (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

     (e)  The obligations of the Company under this Section shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each director of the Company, to each officer of the Company who
has signed a Registration Statement and to each person, if any, who controls the
Company within the meaning of the Act.

     8.  Default of Underwriters.  If any Underwriter or Underwriters default in
their obligations to purchase Offered Securities hereunder on either the First
or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed

                                       15
<PAGE>

10% of the total number of shares of Offered Securities that the Underwriters
are obligated to purchase on such Closing Date, CSFBC may make arrangements
satisfactory to the Company for the purchase of such Offered Securities by other
persons, including any of the Underwriters, but if no such arrangements are made
by such Closing Date, the non-defaulting Underwriters shall be obligated
severally, in proportion to their respective commitments hereunder, to purchase
the Offered Securities that such defaulting Underwriters agreed but failed to
purchase on such Closing Date. If any Underwriter or Underwriters so default and
the aggregate number of shares of Offered Securities with respect to which such
default or defaults occur exceeds 10% of the total number of shares of Offered
Securities that the Underwriters are obligated to purchase on such Closing Date
and arrangements satisfactory to CSFBC and the Company for the purchase of such
Offered Securities by other persons are not made within 36 hours after such
default, this Agreement will terminate without liability on the part of any non-
defaulting Underwriter or the Company, except as provided in Section 9 (provided
that if such default occurs with respect to Optional Securities after the First
Closing Date, this Agreement will not terminate as to the Firm Securities or any
Optional Securities purchased prior to such termination). As used in this
Agreement, the term "Underwriter" includes any person substituted for an
Underwriter under this Section. Nothing herein will relieve a defaulting
Underwriter from liability for its default.

     9.  Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect, and if any Offered Securities have been purchased hereunder
the representations and warranties in Section 2 and all obligations under
Section 5 shall also remain in effect. If the purchase of the Offered Securities
by the Underwriters is not consummated for any reason other than solely because
of the termination of this Agreement pursuant to Section 8 or the occurrence of
any event specified in clause (iii), (iv) or (v) of Section 6(d), the Company
will reimburse the Underwriters for all out-of-pocket expenses (including fees
and disbursements of counsel) reasonably incurred by them in connection with the
offering of the Offered Securities.

     10.  Notices. All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives, c/o Credit Suisse First Boston Corporation, Eleven Madison
Avenue, New York, N.Y. 10010-3629, Attention:  Investment Banking Department--
Transactions Advisory Group, or, if sent to the Company, will be mailed,
delivered or telegraphed and confirmed to it at 303 College Road East,
Princeton, New Jersey 08540, Attention: President; provided, however, that any
notice to an Underwriter pursuant to Section 7 will be mailed, delivered or
telegraphed and confirmed to such Underwriter.

     11.  Successors. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and
directors and controlling persons referred to in Section 7, and no other person
will have any right or obligation hereunder.

     12.  Representation of Underwriters.  The Representatives will act for the
several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC will be binding
upon all the Underwriters.

     13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  Applicable Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, without regard to principles
of conflicts of laws.

                          AGREEMENT AND PLAN OF MERGER
                          ----------------------------

          AGREEMENT AND PLAN OF MERGER, dated as of December 21, 1999 (the
"Agreement") by and among ORCHID BIOCOMPUTER, INC., a Delaware corporation
("Parent"), GS ACQUISITION CORP., a Delaware corporation and a wholly owned
subsidiary of Parent ("Merger Sub"), and GENESCREEN INC., a Delaware corporation
(the "Company").

          WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company
have each determined that it is in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein;

          WHEREAS, in furtherance of such acquisition, the Boards of Directors
of Parent, Merger Sub and the Company have each approved the merger (the
"Merger") of Merger Sub with and into the Company, in accordance with the
General Corporation Law of the State of Delaware (the "DGCL") and subject to the
conditions set forth herein, which Merger will result in, among other things,
the Company becoming a wholly owned subsidiary of Parent, and all of the issued
and outstanding shares of the common stock of the Company, $.01 par value per
share (the "Company Common Shares"), and all of the issued and outstanding
shares of Series A Preferred Stock, $.05 par value per share (the "Company
Series A Stock") and Series B Preferred Stock, $.05 par value per share (the
"Company Series B Stock" and, collectively with the Company Series A Stock, the,
"Company Preferred Shares"; the Company Common Shares and the Company Preferred
Shares are sometimes collectively referred to herein as the "Company Shares"),
of the Company, will be exchanged and converted into shares of Series E
Convertible Preferred Stock, par value $.001 per share (the "Parent Preferred
Stock"), of Parent or cash on the terms described herein and in the Private
Placement Memorandum (as hereafter defined); and

          WHEREAS, as a condition to the willingness of, and as an inducement
to, Parent and Merger Sub to enter into this Agreement, contemporaneously with
the execution and delivery of this Agreement, certain holders of Company Common
Shares and Company Preferred Shares are entering into agreements (the
"Stockholder Agreements") in the form of Exhibit A attached hereto, providing
for certain actions relating to the transactions contemplated by this Agreement,
including their agreement to vote their respective Company Common Shares and
Company Preferred Shares in favor of the Merger.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, Parent, Merger Sub and the Company hereby
agree as follows:

ARTICLE I

THE MERGER

     1.1  THE MERGER.  At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
provisions of the DGCL, Merger Sub shall be merged with and into the Company,
the separate corporate existence of Merger Sub shall cease and the Company
shall, as the surviving corporation in the Merger, continue its existence

                                       1
<PAGE>

under the provisions of the DGCL as a wholly owned subsidiary of Parent. The
Company as the surviving corporation after the Merger is hereinafter sometimes
referred to as the "Surviving Corporation."

     1.2  EFFECTIVE TIME.  As promptly as practicable after the satisfaction
or, to the extent permitted hereunder, waiver of the conditions set forth in
Article VI of this Agreement, the parties hereto shall cause the Merger to be
consummated by filing the Certificate of Merger substantially in the form of
Exhibit B-1 (the "Certificate of Merger"), along with a certified copy of this
Agreement, if required, with the Secretary of State of the State of Delaware,
executed in accordance with the relevant provisions of the DGCL and immediate
filing thereafter of the Restated Certificate of Incorporation of the Company
substantially in the form of Exhibit B-2 (the date and time of such filing of
the Certificate of Merger, or such later date and time as may be specified in
the Certificate of Merger by mutual agreement of Parent, Merger Sub and the
Company, being the "Effective Time").

     1.3  EFFECT OF THE MERGER.  At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the DGCL.  Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time all the property, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

     1.4  CERTIFICATE OF INCORPORATION AND BY-LAWS OF SURVIVING CORPORATION.
Unless otherwise determined by Parent prior to the Effective Time, at the
Effective Time, the Certificate of Incorporation of the Company, as amended by
the Certificate of Merger, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by the DGCL.  The by-
laws of the Merger Sub shall be the by-laws of the Surviving Corporation until
thereafter amended as provided by the DGCL.

     1.5  DIRECTORS AND OFFICERS.  The directors of Merger Sub immediately
prior to the Effective Time shall be the initial directors of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation of the Surviving Corporation.  The officers of the Merger Sub
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, in each case until their respective successors are duly
elected or appointed and qualified or until their earlier death, resignation or
removal in accordance with the Surviving Corporation's Certificate of
Incorporation and by-laws.  Prior to the Effective Time, the Company shall
deliver to Parent resignation letters of each of the directors of the Company to
be effective as of such Effective Time.

     1.6  ESCROW FUND; MERGER CONSIDERATION; CONVERSION OF COMPANY COMMON SHARES
AND COMPANY PREFERRED SHARES.

     (a) On or prior to the Closing Date (i) Parent, the Company and the
Stockholders' Representative (as defined below) shall enter into an Escrow
Agreement substantially in the form attached hereto as Exhibit G (the "Escrow
Agreement") with State Street Bank and Trust Company, as escrow agent (the
"Escrow Agent").  At the Closing, portions of the Parent Preferred Shares and
Aggregate Merger Cash Consideration ( as defined below in Section 1.6(b))

                                       2
<PAGE>

as specified in the Escrow Agreement shall be deposited by Parent in an escrow
fund (the "Escrow Fund") to the Escrow Agent which shall be held by the Escrow
Agent in such capacity. Such Parent Preferred Shares held in the Escrow Fund
shall be beneficially owned by the holders on whose behalf such shares were
deposited in the Escrow Fund and shall be available to compensate Parent as
provided in Article VIII and in the Escrow Agreement.

     (b) The aggregate amount of cash and securities to be paid to the
stockholders of the Company (each, a "Company Stockholder" and collectively, the
"Company Stockholders") upon the conversion of, and as consideration for, all of
the issued and outstanding Company Shares at the Effective Time shall equal
$18,000,000 (the "Aggregate Merger Consideration").  The Aggregate Merger
Consideration shall be comprised of 4,000,000 shares of Parent Preferred Stock
having the rights, preferences and terms set forth in that certain private
placement offering (the "Offering") of Parent pursuant to Parent's Confidential
Private Placement Memorandum dated as of May 5, 1999, as amended and
supplemented to date (the "Private Placement Memorandum") ( a copy of which will
be delivered to each such Company Stockholder prior to the Effective Time) and
in Section 1.6 of the Parent Disclosure Schedule.  Each Company Stockholder
shall be entitled to that portion of the aggregate Merger Stock Consideration
(as defined in Section 1.6(c)(i)) as determined in accordance with the rights
and preferences of each class and series of capital stock of the Company as set
forth in the Company's Certificate of Incorporation and described in Section
1.6(b) of the Parent Disclosure Schedule.  Notwithstanding the foregoing, if
Parent determines that Regulation D promulgated under the Securities Act of
1933, as amended (the "Securities Act"), does not permit it to issue shares of
Parent Preferred Stock to any Company Stockholder which is not an "accredited
investor" as such term is defined in the Securities Act, such Company
Stockholder (an "Unaccredited Company Stockholder") shall be issued, at Parent's
discretion, cash in the amount of $4.50 for each share of Parent Preferred Stock
to which the Unaccredited Company Stockholder would have been entitled in lieu
of shares of such Parent Preferred Stock (the "Merger Cash Consideration", the
aggregate Merger Cash Consideration paid to all of the Unaccredited Company
Stockholders, hereinafter referred to as the "Aggregate Merger Cash
Consideration").

     (c) At the Effective Time, by virtue of the Merger and without any action
on the part of the parties hereto or the holders of the following securities:

          (i) Subject to the other provisions of this Article I, each Company
Share issued and outstanding immediately prior to the Effective Time (other than
any Company Shares to be canceled pursuant to Section 1.7 and any Dissenting
Shares (as defined in Section 1.17)) shall be converted automatically into the
right to receive (i) the Exchange Ratio Fraction of a fully paid and
nonassessable share of Parent Preferred Stock, together with cash, if any, in
lieu of any fraction of a share of Parent Preferred Stock, pursuant to Section
1.11 (collectively, the "Merger Stock Consideration"), less such Company
Stockholder's share of the Escrow Fund, and (ii) if such Company Share is held
by an Unaccredited Company Shareholder, such stockholder's portion of the
Aggregate Merger Cash Consideration.

          (ii) For purposes of this Agreement, the "Exchange Ratio Fraction"
shall mean the quotient (calculated to the nearest five (5) decimal places)
obtained by dividing (x) the result obtained from subtracting the Aggregate

                                       3
<PAGE>

Merger Cash Consideration from the Aggregate Merger Consideration by (y) $4.50,
and by dividing the quotient computed thereby by the Company Number Shares (as
defined below).  As used herein, the "Company Number Shares" means the sum of
(A) (i) all Company Common Shares outstanding immediately prior to the Effective
Time (including all Company Common Shares issued upon the exercise or
cancellation of any options to purchase Company Common Shares or any warrants to
purchase Company Common Shares or upon the conversion or exchange of any Company
Preferred Shares), minus (ii) Company Common Shares to be canceled pursuant to
Section 1.7 and any Dissenting Shares (as defined in Section 1.16).

          (iii)  As of the Effective Time, all Company Common Shares and all
Company Preferred Shares issued and outstanding immediately prior to the
Effective Time shall no longer be outstanding and all Company Common Shares and
all Company Preferred Shares shall automatically be canceled and retired and
shall cease to exist, and each holder of a certificate representing any such
Company Common Shares and all Company Preferred Shares shall cease to have any
rights with respect thereto, except the right to receive its portion of the
Merger Stock Consideration and any cash in lieu of fractional shares of Parent
Preferred Stock to be issued or portion of the Aggregate Merger Cash
Consideration paid in consideration therefor upon surrender of such certificate
in accordance with Section 1.12 hereof, without interest (less, in each case,
the Parent Preferred Stock and the portion of Aggregate Merger Cash
Consideration representing the Escrow Fund).

     1.7  CANCELLATION OF TREASURY SHARES.  Each share of Company Common
Shares or Company Preferred Shares held in the treasury of the Company and each
share of Company Common Shares or Company Preferred Shares, if any, owned by
Merger Sub or Parent, immediately prior to the Effective Time shall be canceled
and extinguished without any conversion thereof.

     1.8  STOCK OPTIONS.  Under the terms of the Company's Amended and
Restated 1991 Stock Option Plan (the "Company Stock Plan"), all outstanding
employee and consultant stock options and all non-employee director stock
options, including without limitation, the incentive stock options and non-
qualified stock options issued pursuant to the Company Stock Plan (collectively
the "Company Options") outstanding at the Effective Time shall be deemed to be
exercised immediately prior to the Effective Time for the number of additional
shares of  Company Common Stock as provided in the Company Stock Plan (the
"Deemed Exercised Shares").  The Company shall take all actions necessary or
reasonably requested by Parent to ensure that following the Effective Time no
holder of any Company Options or rights pursuant to, nor any participant in, the
Company Stock Plan, or any other plan, program or arrangement providing for the
issuance or grant of any interest in respect of the capital stock of the Company
and any of its Subsidiaries or Affiliated Entities will have any right
thereunder to acquire equity securities, or any right to payment in respect of
the equity securities, of the Company, any of its Subsidiaries or Affiliated
Entities or the Surviving Corporation, except as provided in Section 1.9 below.

          1.9  REPURCHASE RIGHTS.  In order to provide incentive to certain
employees of the Company to remain in the employ of the Parent during a
transition period following the Effective Time, each employee listed on Section
1.9 of the Company Disclosure Schedule hereto (each, a "Key Employee") shall
have the right to require Parent to repurchase at a price of $4.50 per share

                                       4
<PAGE>

the Parent Preferred Stock received by such Key Employee in connection with the
Merger in such number and at such intervals as is set forth on Section 1.9 of
the Company Disclosure Schedule (the "Repurchase Right"). In order to exercise,
and as a condition precedent to the exercise of, the Repurchase Right and to
receive cash in exchange for such Key Employee's shares of Parent Preferred
Stock, the Key Employee must be employed by Company, Parent or any of the
Subsidiaries of Parent on the respective dates set forth on Section 1.9 of the
Company Disclosure Schedule corresponding with the date on which a Repurchase
Right matures; provided, that, each of Keith Brown and William Baxter shall be
entitled to exercise his respective Repurchase Right whether or not they
continue to be employed by or associated with the Parent. If a Key Employee is
not so employed by Parent on the date a Repurchase Right of such Key Employee
matures, such Key Employee shall be entitled to retain the Parent Preferred
Stock covered by such Repurchase Right. If a Key Employee is terminated by
Parent for any reason other than Cause (as defined below), all unaccrued
Repurchase Rights shall be accelerated and exercisable immediately upon
termination. Notwithstanding anything to the contrary contained herein, no
Repurchase Right shall be exercisable prior to the expiration of thirty (30)
days from the Effective Time and all Repurchase Rights shall terminate upon the
consummation by Parent of a Qualified IPO (as defined).

     The purchase price for any Parent Preferred Stock purchased under a
Repurchase Right shall be subject to appropriate adjustment for any stock split,
reverse stock split, recapitalization or other change in the capitalization of
Parent.

     1.10  CAPITAL STOCK OF MERGER SUB.  Each share of common stock, par value
$.001 per share, of Merger Sub (the "Merger Sub Common Stock") issued and
outstanding immediately prior to the Effective Time shall be converted into and
exchanged for one validly issued, fully paid and nonassessable share of Common
Stock, par value $.01 per share, of the Surviving Corporation.  Each stock
certificate of Merger Sub evidencing ownership of any Merger Sub Common Stock
shall continue to evidence ownership of such shares of capital stock of the
Surviving Corporation.

     1.11  FRACTIONAL SHARES.  No fraction of a share of Parent Preferred
Stock will be issued hereunder, but in lieu thereof each holder of Company
Shares who would otherwise be entitled to a fraction of a share of Parent
Preferred Stock (after aggregating all fractional shares of Parent Preferred
Stocks to be received by such holder) shall receive from Parent an amount of
cash (rounded up or down, as the case may be, to the nearest whole cent) equal
to the product of such fraction multiplied by the $4.50.

     1.12  SURRENDER OF CERTIFICATES.

          (a) EXCHANGE AGENT.  Prior to the Effective Time, Parent shall
designate Worsham, Forsythe & Woodridge, L.L.P to act as Exchange Agent
hereunder.

          (b) PARENT TO PROVIDE PARENT PREFERRED STOCK.  Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for exchange
in accordance with this Article I, through such reasonable procedures as Parent
may adopt, the shares of Parent Preferred Stock issuable pursuant to Section 1.6
in exchange for outstanding Company Common Shares and outstanding Company
Preferred Shares, together with an estimated amount of cash to be

                                       5
<PAGE>

paid pursuant to Section 1.6 as Aggregate Merger Cash Consideration and pursuant
to Section 1.11 in lieu of fractional shares.

          (c) EXCHANGE PROCEDURES.  Promptly after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of a certificate or certificates (the "Certificates") which immediately
prior to the Effective Time represented outstanding Company Common Shares and
Company Preferred Shares whose shares were converted into the right to receive
shares of Parent Preferred Stock and/or a portion of the Aggregate Merger Cash
Consideration pursuant to Section 1.6, a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as Parent may
reasonably specify) and instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of Parent
Preferred Stock, (ii) the portion of Aggregate Merger Cash Consideration, if
any, to which such holder is entitled pursuant to Section 1.6 hereof and/or
(iii) cash in lieu of the fraction of a share of Parent Preferred Stock, if any,
pursuant to Section 1.11 hereof.  Upon surrender of a Certificate for
cancellation to the Exchange Agent, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holder of such Certificate shall be entitled to receive in exchange
therefor, (i) a certificate representing the number of whole shares of Parent
Preferred Stock (less the shares of Parent Preferred Stock representing the
Escrow Fund), (ii) the portion of the Merger Cash Consideration, if any,
applicable to such holder (less any cash representing a portion of the Escrow
Fund) and/or (iii) payment in lieu of fractional shares which such holder has
the right to receive pursuant to Section 1.11, and the Certificate so
surrendered shall forthwith be canceled.  Until so surrendered, each outstanding
Certificate that, prior to the Effective Time, represented Company Common Shares
or Company Preferred Shares will be deemed from and after the Effective Time,
for all corporate purposes, other than the payment of dividends, to evidence the
ownership of the number of full shares of Parent Preferred Stock into which such
Company Common Shares and Company Preferred Shares shall have been so converted
and/or the right to receive such portion of the Merger Cash Consideration and/or
the right to receive an amount in cash in lieu of the issuance of any fractional
shares in accordance with Section 1.11.  Any portion of the shares of Parent
Preferred Stock or Merger Cash Consideration deposited with the Exchange Agent
pursuant to this Section 1.12(c) which remains undistributed to the holders of
the Certificates representing Company Common Shares or Company Preferred Shares
for twelve (12) months after the Effective Time shall be delivered to Parent,
upon demand, and any holders of Company Common Shares or Company Preferred
Shares who have not theretofore complied with this Article I shall thereafter
look only to Parent for Parent Preferred Stock, such portion, if any, of the
Merger Cash Consideration and/or any cash in lieu of fractional shares of Parent
Preferred Stock and any dividends or distributions with respect to Parent
Preferred Stock to which such holders may be entitled.

          (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions declared or made after the Effective Time with respect to
Parent Preferred Stock with a record date after the Effective Time will be paid
to the holder of any unsurrendered Certificate with respect to the shares of
Parent Preferred Stock represented thereby until the holder of record of such
Certificate shall surrender such Certificate.  Subject to applicable escheat
Law, following surrender of any such Certificate, there shall be paid to the
record holder

                                       6
<PAGE>

of the certificates representing whole shares of Parent Preferred Stock issued
in exchange therefor, without interest, at the time of such surrender, the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Preferred Stock.

          (e) TRANSFERS OF OWNERSHIP.  If any certificate for shares of Parent
Preferred Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the Person
requesting such exchange will have paid to Parent, or any agent designated by
it, any transfer or other taxes required by reason of the issuance of a
certificate for shares of Parent Preferred Stock in any name other than that of
the registered holder of the certificate surrendered, or established to the
satisfaction of Parent or any agent designated by it that such tax has been paid
or is not payable.

          (f) NO LIABILITY.  Notwithstanding anything to the contrary in this
Agreement, none of the Exchange Agent, Parent, Merger Sub or the Surviving
Corporation shall be liable to a holder of Company Common Shares or Company
Preferred Shares for any Parent Preferred Stock or any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar Law.

          (g) WITHHOLDING OF TAX.  Parent or the Exchange Agent will be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Company Common Shares or any holder of Company
Preferred Shares, as the case may be, such amounts as Parent (or any Affiliate
thereof) or the Exchange Agent are required to deduct and withhold with respect
to the making of such payment under the Code, or any provision of federal,
state, local or foreign tax law.  To the extent that amounts are so withheld by
Parent or the Exchange Agent, such withheld amounts will be treated for all
purposes of this Agreement as having been paid to the holder of the Company
Common Shares or Company Preferred Shares, as the case may be, in respect of
whom such deduction and withholding were made by Parent.

     1.13  FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON SHARES AND COMPANY
PREFERRED SHARES.  All shares of Parent Preferred Stock issued upon the
surrender for exchange of Company Common Shares and Company Preferred Shares in
accordance with the terms of this Article I (including any cash paid as a
portion of the Aggregate Merger Cash Consideration and/or for fractional shares
paid in respect thereof) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Company Common Shares and Company
Preferred Shares under this Article I, and there shall be no further
registration of transfers on the records of the Surviving Corporation of Company
Common Shares or Company Preferred Shares which were outstanding immediately
prior to the Effective Time.  If, after the Effective Time, Certificates are
presented to the Surviving Corporation for any reason, they shall be canceled
and exchanged as provided in this Article I.

     1.14  CLOSING.  Unless this Agreement shall have been terminated and the
transactions contemplated by this Agreement abandoned pursuant to the provisions
of Article VII, and subject to the provisions of Article VI, the closing of the
Merger (the "Closing") will take place at 10:00 a.m. (Eastern time)

                                       7
<PAGE>

on a date (the "Closing Date") to be mutually agreed upon by the parties, which
date shall be not later than the third Business Day after all the conditions set
forth in Article VI shall have been satisfied (or waived in accordance with
Section 7.5, to the extent the same may be waived), unless another time and/or
date is agreed to in writing by the parties. The Closing shall take place at the
offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., One Financial
Center, Boston, Massachusetts, unless another place is agreed to in writing by
the parties.

     1.15  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Parent
Preferred Stock and/or cash (whether as a portion of the Aggregate Merger Cash
Consideration and/or for fractional shares, if any), as may be required pursuant
to Sections 1.6 or 1.11; provided, however, that Parent may, as a condition
precedent to the issuance or payment thereof, require the owner of such lost,
stolen or destroyed certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against Parent
or the Exchange Agent with respect to the Certificates alleged to have been
lost, stolen or destroyed.

     1.16  DISSENTERS' RIGHTS.  All Persons who have executed and delivered a
Stockholder Agreement shall have consented to the Merger and shall have
delivered their stock certificates in accordance with the terms hereof.
Notwithstanding anything in this Agreement to the contrary, any Company Common
Shares or Company Preferred Shares outstanding immediately prior to the
Effective Time and held by a holder who has not voted in favor of the Merger or
delivered a valid, unrevoked proxy in favor of the Merger, or consented thereto
in writing and who has delivered written notice to the Company objecting to the
Merger and demanding payment for his shares as required in accordance, and has
otherwise complied, with the applicable provisions of the DGCL ("Dissenting
Shares"), shall not be converted into the right to receive the Parent Preferred
Stock or such holder's portion of the Aggregate Merger Cash Consideration,
unless and until such holder fails to elect to dissent from the Merger or
effectively withdraws or otherwise loses his right to payment of the fair value
of his shares under the provisions of the DGCL.  If, after the Effective Time,
any such holder fails to perfect or effectively withdraws or loses his right to
such payment, such Dissenting Shares shall thereupon be treated as if they had
been converted as of the Effective Time into the right to receive Parent
Preferred Stock to which such holder is entitled or such holder's portion of the
Aggregate Merger Cash Consideration, without interest or dividends thereon.  Any
amounts paid to holders of Dissenting Shares in an appraisal proceeding will be
paid by the Surviving Corporation out of its own funds and will not be paid by
Parent or Merger Sub.  The Company shall not, except with the prior written
consent of Parent, make any payment with respect to any such demands or offer to
settle or settle any such demands.

     1.17  FURTHER ASSURANCES.  If at any time after the Effective Time, the
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation its right, title or interest in, to or under any of
the rights, privileges, immunities, powers, purposes, franchises, properties or
assets of the Company or Merger Sub, or (b) otherwise to carry out the purposes
of this Agreement, the

                                       8

Surviving Corporation and its proper officers and directors or their designees
shall be authorized to solicit in the name of the Company or Merger Sub any
third party consents or other documents required to be delivered by any third
party, to execute and deliver, in the name and on behalf of the Company or
Merger Sub, all such deeds, bills of sale, assignments and assurances and do, in
the name and on behalf of the Company or Merger Sub, all such other acts and
things necessary, desirable or proper to vest, perfect or confirm its right,
title or interest in, to or under any of the rights, privileges, immunities,
powers, purposes, franchises, properties or assets of the Company or Merger Sub
and otherwise to carry out the purposes of this Agreement.

     1.18  CLOSING OF COMPANY TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed and no transfer of Company Common
Shares or Company Preferred Shares shall thereafter be made.  If, after the
Effective Time, certificates representing shares of Company Common Shares or
Company Preferred Shares are presented to the Surviving Corporation, they shall
be canceled and presented to the Exchange Agent in accordance with Section 1.12.

complaint received by the Company from a customer during the twelve (12) month
period preceding the date hereof, the net affect of which would be the likely
cancellation or termination of an agreement having a value in excess of
$100,000. Complete copies of all Material Agreements have been provided by the
Company to Parent and no oral Material Agreements exist. Each such Material
Agreement is in full force and effect, is a valid and

binding obligation of the Company or such Subsidiary or Affiliated Entity and is
enforceable against the Company or such Subsidiary or Affiliated Entity in
accordance with its terms and the Company does not have Knowledge that any
Material Agreement is not a valid and binding agreement of the other parties
thereto. Except as set forth in Section 2.6 of the Company Disclosure Schedule,
each Material Agreement is enforceable in each case except to the extent the
enforcement thereof may be limited by (A) bankruptcy, insolvency,
reorganization, moratorium or other similar law now or hereafter in effect
relating to creditors' rights generally and (B) general principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law). Except as set forth on Section 2.6 of the Company Disclosure Schedule,
(i) no condition exists or, to the Company's Knowledge, event has occurred which
(whether with or without notice or lapse of time or both, or the happening or
occurrence of any other event) would result in a loss of rights or an
acceleration of an obligation or result in the creation of any Lien thereunder
or pursuant thereto, or would constitute a default by the Company or any of its
Subsidiary or Affiliated Entities or, to the Company's Knowledge, any other
party thereto under, or result in a right in termination of, any Material
Agreement. The Company and its Subsidiary and Affiliated Entities are in
compliance in all material respects with the terms of the Company Approvals,
except as set forth in Section 2.6 of the Company Disclosure Schedule. The
continuation, validity, enforceability and effectiveness of each Material
Agreement will not be affected by the consummation of the transactions
contemplated by this Agreement, except as set forth on Section 2.5(a) of the
Company Disclosure Schedule. Furthermore, no party to a Material Agreement has
repudiated any provision thereof and communicated such repudiation to the
Company, and there are no negotiations pending or in progress to revise any
material terms of any Material Agreement.

          2.7  COMPLIANCE WITH AGREEMENTS AND LAW.  Neither the Company nor any
of its Subsidiaries or Affiliated Entities is in conflict with, or in default or
violation of, any Law, Regulation or Order applicable to the Company or such
Subsidiary or by which its or any of their respective properties is bound or
affected. The Company has all requisite licenses, permits, certificates,
authorizations and approvals including environmental, health and safety and
employee health and safety permits, from foreign, federal, state and local
authorities necessary to conduct the business as currently conducted
(collectively, the "Permits"), all of which Permits are set forth in Section 2.7
of the Company Disclosure Schedule. All of the Permits identified in Section 2.7
of the Company Disclosure Schedule are in full force and effect, and to the
Company's Knowledge, no party thereto is in default under any of such Permits
and no event has occurred and no condition exists which, with the giving of
notice, the passage of time, or both, would constitute a default thereunder. No
action or claim is pending or, to the Company's Knowledge, threatened, to revoke
or terminate any Permit identified in Section 2.7 of the Company Disclosure
Schedule. Except as set forth in Section 2.7 of the Company Disclosure Schedule,
the Company is not nor has it been in violation of any Law, rule, Regulation,
ordinance or court or administrative order (including, without limitation, those
relating to building, zoning, environmental, disposal or hazardous substances,
land use, health and safety and employee health and safety matters). Except as
set forth on Section 2.7 of the Company Disclosure Schedule, neither the Company
nor its Subsidiaries or Affiliated Entities has received any notice or
communication from any foreign, federal, state or local governmental or
regulatory authority or otherwise of any such violation and, to the Company's
Knowledge, no such notice or communication is threatened.

employee or former employee of the Company or any of its ERISA Affiliates,
whether or not such plan has been terminated (the "Company Benefit Plans").
Except as set forth in Section 2.15(a) of the Company Disclosure Schedule, there

Benefit Plans. All contributions required to be made to any Company Benefit Plan
under applicable law or the terms of the respective Company Benefit Plan have

for contributions to each Company Benefit Plan for the current plan years.
Except as disclosed on Section 2.15(e) of the Company Disclosure Schedule, or

beneficiary under any Company Benefit Plan.

          (f) Each Company Benefit Plan intended to be "qualified" within the
meaning of Section 401(a) of the Code and the trusts maintained thereunder that
are intended to be exempt from taxation under Section 501(a) of the Code have
received a favorable determination or opinion letter indicating that they are so
qualified, and, to the Company's Knowledge, no event has occurred since the date
of said letter(s) that will adversely affect the qualification of such Company
Benefit Plan.

          (i) Except as set forth in Section 2.15(i) of the Company Disclosure
Schedule, the execution, delivery and performance of, and consummation of the
transactions contemplated by, this Agreement, or the Stockholder Agreements will
not entitle any current or former employee or officer of the Company or any
ERISA Affiliate to severance pay, unemployment compensation or any other
payment, except as expressly provided in this Agreement.

          (j) Except as would not be material in any respect to the Company,
there are no pending or, to the Company's Knowledge, threatened or anticipated
claims by or on behalf of any Company Benefit Plan, by any employee or
beneficiary covered under any such Company Benefit Plan or otherwise involving
any such Company Benefit Plan (other than routine claims for benefits).

<PAGE>

               (iv) There is no Litigation pending or, to the Company's
     Knowledge, threatened nor has Company received any written communication

     third party;

               (vi) Except as set forth in Section 2.5(a) of the Company
     Disclosure Schedule, the execution, delivery and performance by the Company
     of this Agreement, and the consummation of the transactions contemplated
     hereby will not result in the loss or impairment of or give rise to any
     right of any third party to terminate any of the Company's or any of its
     Subsidiaries' or Affiliated Entities' right to own any of the Intellectual
     Property Rights owned by the Company or any of its Subsidiaries or
     Affiliated Entities or to use any Intellectual Property Rights licensed to
     the Company or any of its Subsidiaries pursuant to the license agreements,
     nor require the consent of any Governmental Authority or third party in
     respect of any such Intellectual Property Rights;

          (e) All trademarks of the Company and its Subsidiaries have been in
continuous use by the Company or its Subsidiaries or Affiliated Entities.  To
the Company's Knowledge (i) there has been no prior use of such trademarks by
any third party which would confer upon said third party superior rights in such

substantially consistent with the Company's standard forms thereof.  Except

been no material disclosure by the Company or any Subsidiary or Affiliated
Entity of the Company of material confidential information or trade secrets.

          (g) The Company has undertaken the review and assessment of the
business and operations of itself and its Subsidiaries that could be adversely
affected by its or their failure to be Year 2000 Compliant.  The Company has
requested certification from the outside vendors listed in the Company
Disclosure Schedule that the computer system, hardware, software, database,
device and/or equipment purchased from each such vendor and used internally by
the Company, or used by such vendor in the performance of work for the Company,
is or prior to and after January 1, 2000 will be Year 2000 Compliant, and has
provided copies of all such certification received to date to Parent.  Based on
its review and assessment, the Company has no reason to believe any material
liability or expense will result from or arise out of failure of any of its or
its Subsidiaries or Affiliated Entities, computer systems, hardware, software,
databases, devices and/or equipment to be Year 2000 Compliant.

payable under all such policies and bonds have been paid and the Company and its
Subsidiaries and Affiliated Entities are otherwise in full compliance with the
terms of such policies and bonds (or other policies and bonds providing
substantially similar insurance coverage), and the Company shall, and shall
cause its Subsidiaries or Affiliated Entities to, maintain in full force and
effect all such insurance during the period from the date hereof through the
Closing Date.  To the Company's Knowledge, such policies of insurance and bonds
are of the type and in amounts customarily carried by Persons conducting
businesses similar to those of the Company and its Subsidiaries or Affiliated
Entities and reasonable in light of the assets of the Company and its
Subsidiaries or Affiliated Entities.  As of the date hereof, the Company has not

retrospective premium adjustment or other experienced-based liability on the
part of the Company.

issuer of any insurance policy of the Company or any notice that a defense will
be afforded with reservation of rights, or (B) any notice of cancellation or any
other indication that any insurance policy is no longer in full force or effect
or will or will not be renewed or that the issuer of any policy is not willing
or able to perform its obligations thereunder.

          (d) The Company has paid all premiums due, and has otherwise performed
all of its respective obligations, under each policy to which the Company is a
party or that provides coverage to the Company or a director thereof.

This Agreement has been duly executed and delivered by each of Parent and Merger
Sub and, assuming due authorization, execution and delivery hereof by the
Company, constitutes a legal, valid and binding obligation of each of Parent and
Merger Sub, enforceable against each of Parent and Merger Sub in accordance with
its terms, in each case except to the extent that the enforcement hereof may be
limited by (A) bankruptcy, insolvency, reorganization, moratorium or other
similar law now or hereafter in effect relating to creditors' rights generally
and (B) general principles of equity (regardless of whether enforceability is
considered in a proceeding in equity or at law).  No other corporate proceedings
are required by Parent other than the approval of the Board of Directors of
Parent and Merger Sub.

     3.4  APPROVALS.  The execution and delivery by Parent and Merger Sub of
this Agreement or any instrument required by this Agreement to be executed and

<PAGE>

its respective obligations under this Agreement or any instrument required by

Closing shall not, require Parent or Merger Sub to obtain any consent, approval,

Governmental Authorities set forth in Section 3.4(A) or (B) above, the execution
and delivery by Parent and Merger Sub of this Agreement or any instrument
required by this Agreement to be executed and delivered by Parent or Merger Sub
at the Closing do not, and the performance of this Agreement by each of Parent
or Merger Sub of its respective obligations under this Agreement or any
instrument required by this Agreement to be executed and delivered by Parent or
Merger Sub at the Closing will not, (i) conflict with or violate the Certificate
of Incorporation or By-laws of Parent or the Certificate of Incorporation or By-
laws of Merger Sub, (ii) conflict with or violate any Law, Order or Regulation
in each case applicable to Parent or Merger Sub or by which either of its

contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which the Parent or Merger Sub is a party or by which Parent or
Merger Sub or any of their respective properties is bound or affected.

     3.6   FINANCIAL STATEMENTS.  Parent has delivered to the Company:  (a)
audited balance sheets of Parent as at December 31 in each of the years 1996
through 1998 , and the related audited consolidated statements of income,
changes in stockholders' equity, and cash flow for each of the fiscal years then
ended, together with the report thereon of KPMG Peat Marwick LLP, independent
certified public accountants (the most recent of which, the "Parent Balance
Sheet"), and (b) unaudited balance sheets of the Parent as at March 31, 1999,
June 30, 1999 and September 30, 1999 and the related unaudited consolidated
statements of income, changes in stockholders' equity, and cash flow for the
three, six and nine months then ended, including in each case the notes thereto.
Such financial statements and notes (collectively, the "Parent Financial
Statements"), are true, correct and complete and fairly present the financial
condition and the results of operations, changes in stockholders' equity, and
cash flow of the Parent in all material respects as at the respective dates of
and for the periods referred to in such financial statements, all in accordance
with GAAP, subject, in the case of interim financial statements, to normal
recurring year-end adjustments (the effect of which will not, individually or in
the aggregate, be materially adverse) and the absence of notes (that, if
presented, would not differ materially from those included in the Parent Balance
Sheet).  Except as disclosed therein, the Parent Financial Statements reflect
the consistent application of such accounting principles throughout the periods
involved.

     3.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in
Section 3.7 of the Parent Disclosure Schedule, since September 30, 1999, Parent
has conducted its business only in

                                       32
<PAGE>

the ordinary and usual course and in a manner consistent with past practice and,
since such date, there has not occurred any event, development or change which,
individually or in the aggregate, has resulted in or is reasonably likely to
result in a Material Adverse Effect.

     3.8  BROKERS.  No broker, financial advisor, finder or investment banker
or other Person (other than Punk Ziegel & Company) is entitled to any broker's,
financial advisor's, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of Parent.  Parent has heretofore furnished to the Company a complete
and correct copy of all agreements set forth in Section 3.7 of the Parent
Disclosure Schedule between Parent and financial advisor pursuant to which such
firm would be entitled to any payment relating to the transactions contemplated
hereunder.

     3.9  DISCLOSURE.  The representations and warranties and statements of
Parent contained in this Agreement (including the Parent Disclosure Schedule) do
not contain, and will not contain at the Closing Date, any untrue statement of a
material fact, and do not omit, and will not omit at the Closing Date, to state
any material fact necessary to make such representations, warranties and
statements, in light of the circumstances under which they are made, not
misleading.  There is no fact known to Parent that has not been disclosed to the
Company in this Agreement (including in the Parent Disclosure Schedule) that is
reasonably likely to have a Material Adverse Effect on Parent.

     4.2  NO SOLICITATION OF OTHER PROPOSALS.

          (a) From the date hereof until the earlier of the Effective Time or
the termination of this Agreement in accordance with its terms, the Company
shall not, nor shall it permit any of its Subsidiaries or Affiliated Entities or
any of its or their respective officers, directors, employees, representatives
or agents (collectively, the "Company Representatives") to, and the Company
shall use its best efforts to cause each Company Stockholder who is an Affiliate
not to, directly or indirectly, (i) solicit, facilitate, initiate or encourage,
or take any action to solicit, facilitate, initiate or encourage, any inquiries
or the making of any proposal or offer that constitutes an Acquisition Proposal
or (ii) participate or engage in discussions or negotiations with, or provide
any information to, any Person concerning an Acquisition Proposal or which might
reasonably be expected to result in an Acquisition Proposal.

          For purposes of this Agreement, the term "Acquisition Proposal" shall
mean any inquiry, proposal or offer from any person (other than Parent, Merger
Sub or any of their Affiliates) relating to:

               (1) any merger, consolidation, recapitalization, liquidation or
     other direct or indirect business combination, involving the Company or any
     Subsidiary or Affiliated Entity or the issuance or acquisition of shares of
     capital stock or other equity securities of the Company or any Subsidiary
     or Affiliated Entity representing 10% or more of the outstanding capital
     stock of the Company or such Subsidiary or Affiliated Entity or any tender
     or exchange offer that if consummated would result in any Person, together
     with all Affiliates thereof, beneficially owning shares of capital stock or
     other equity securities of the Company or any Subsidiary or Affiliated
     Entity representing 10% or more of the outstanding capital stock of the
     Company or such Subsidiary or Affiliated Entity, or

     Intellectual Property Right, or any significant portion of the business or
     other assets of the Company or any Subsidiary or Affiliated Entity, or any
     other transaction, the consummation of which could reasonably be expected
     to impede, interfere with, prevent or materially delay the consummation of
     the transactions contemplated hereby or which would reasonably be expected
     to diminish significantly the benefits to Parent or its Affiliates of the
     transactions contemplated hereby.

The Company shall immediately cease and cause to be terminated and shall cause
all Company Representatives (and shall use its best efforts to cause its non-
officer and non-director Affiliates) to terminate all existing discussions or
negotiations with any Persons conducted heretofore with respect to, or that
could reasonably be expected to lead to, an Acquisition Proposal.  The Company
shall promptly notify all Company Representatives and non-officer and non-
director Affiliates of its obligations under this Section 4.2.

     Acquisition Proposal other than the Merger,

               (2) withdraw or modify or propose to withdraw or modify in a
     manner adverse to Parent or Merger Sub its approval or recommendation of
     the Merger, this Agreement or the transactions contemplated hereby,

     recommendation of this Agreement or the Merger, fail to do so within two
     (2) Business Days after such request is made,

               (4) enter, or cause the Company or any Subsidiary or Affiliated
     Entity to enter, into any letter of intent, agreement in principle,
     acquisition agreement or other similar agreement related to any Acquisition
     Proposal, or

               (5) resolve or announce its intention to do any of the foregoing.

obtain all votes, consents, and approvals of the Company Stockholders necessary
for the approval of this Agreement under the Delaware General Corporation Law
and its Certificate of Incorporation and By-laws.  If Company Stockholders'
Meeting has been called and noticed, the Company shall not postpone or adjourn
(other than for the absence of a quorum and then only to a future date specified
by Parent) the Company Stockholders' Meeting without the consent of Parent.  The
Company shall solicit from stockholders of the Company consents or  proxies in
favor of the Merger and shall take all other action necessary or advisable to

          PLAN OF MERGER BY AND AMONG ORCHID BIOCOMPUTER, INC., GS ACQUISITION

     connection with the authorization, execution and delivery of this Agreement
     by the Company and Parent and the consummation by them of the transactions
     contemplated hereby and thereby, including the Merger (in connection with
     which Parent and the Company will cooperate with each other in connection
     with the making of all such filings, including providing copies of all such
     documents to the non-filing party and its advisors prior to filings and, if

provided, however, that neither Parent nor any of its Affiliates shall be under
any obligation to (x) make proposals, execute or carry out agreements or submit
to Orders providing for the sale or other disposition or holding separate
(through the establishment of a trust or otherwise) of any assets or categories
of assets material (in nature or amount) of Parent, any of its Affiliates, the
Company or the holding separate of the Company Common Shares or Company
Preferred Shares or imposing or seeking to impose any material limitation on the
ability of Parent or any of its Subsidiaries or Affiliated Entities to conduct
their business or own such assets or to acquire, hold or exercise full rights of

otherwise take any step to avoid or eliminate any impediment which may be
asserted under any Law governing competition, monopolies or restrictive trade
practices which, in the reasonable judgment of Parent, might result in a
limitation of the benefit expected to be derived by Parent as a result of the
transactions contemplated hereby or might adversely affect the Company or Parent
or any of Parent's Affiliates.  Neither party hereto will take any action

                                       39

Company, or debt or other instrument convertible or exchangeable for any voting
or non-voting capital stock, other equity interests, or other voting securities
of the Company, will have any right thereunder or with respect thereto to cause

otherwise affect the remedies available hereunder to the party receiving such
notice.

          (b) Each of the Company and Parent shall give prompt notice to the
other of (i) any notice or other communication from any Person alleging that the

national automated quotation system, in which case the party proposing to issue
such press release or make such public announcement shall use reasonable efforts
to consult in good faith with the other party before issuing any such press
release or making any such public announcement.  Notwithstanding the foregoing,

of Directors of the Company shall grant such approvals and take such actions as
are necessary under such laws and provisions so that the transactions
contemplated hereby and thereby may be consummated as promptly as

of the Company in order to determine any potential exposure of the Surviving
Corporation to liability under ERISA with respect to eligibility requirements
under the Company 401(k) Plan (such evaluation hereinafter referred to as the

clause (iii), and (iv) if the Indemnifying Party is entitled to but fails to

single or partial exercise of any such right preclude other or further exercise
thereof or of any other right.  All rights and remedies existing under this
Agreement are cumulative to, and not exclusive to, and not exclusive of, any

distribution or payment is made upon any Junior Securities, the aggregate
Liquidation Value (as hereinafter defined) of all Series A Preferred Stock
outstanding, and the holders of the Series A Preferred Stock shall not be
entitled to any further distribution. If, upon any such liquidation, dissolution

of stockholders eligible to vote on such matter,

written consent of stockholders is solicited, and shall vote together with the
holders of Common Stock as a single class.

respect to any provision of this Designation unless approved by the affirmative
vote of the holders of at least a majority of the outstanding shares of Series A
Preferred Stock voting together as a separate class.

     (b) In addition to any other vote or consent of stockholders required by
the Certificate of Incorporation, as amended, or the Bylaws of the Corporation
or by law, the affirmative vote of all the holders of the outstanding shares of
Series A Preferred Stock, voting together as a separate class, shall be
necessary to change the Conversion Rate, or the amount or priority of any
distributions upon liquidation of the Corporation with respect to, shares of
Series A Preferred Stock or to amend this Section 4.

     (c) The affirmative vote of the holders of at least a majority of the
outstanding shares of Series A Preferred Stock voting together as a separate
class shall be necessary to increase the number of authorized shares of
preferred stock or authorize or issue any additional shares of any series of
preferred stock or any shares of capital stock of the Corporation of any class,

         -------------------
of this Section 5, each holder of shares of Series A Preferred Stock shall have
the right, at such holders option, at any time or from time to time, to convert
any of such shares of Series A Preferred Stock into fully paid and nonassessable
shares of Common Stock upon the terms hereinafter set forth. Each share of
Series A Preferred Stock shall be converted into fully paid and nonassessable
shares (calculated to the nearest 1/100 of a share)of Common Stock at the
Conversion Rate in effect on the Conversion Date.

     (b) Automatic Conversion. In the event that, at any time while any of the
         --------------------
Series A Preferred Stock shall be outstanding, the Corporation shall consummate
an underwritten public offering on a firm commitment basis pursuant to an
effective registration statement under the Securities Act of 1933, as amended,
covering the offer and sale of Common Stock providing aggregate net proceeds to
the Corporation equal to at least $15,000,000 (a "Qualifying Public Offering"),
then all outstanding shares of Series A Preferred Stock shall, automatically and
without further action on the part of the holders of the Series A Preferred
Stock, be converted
<PAGE>

into shares of Common Stock with the same effect as if the certificates
evidencing such shares had been surrendered for conversion, such conversion to
be effective simultaneously with the closing of such public offering; provided,
however, that certificates evidencing the shares of Common Stock issuable upon
such conversion shall not be issued except on surrender of the certificates for
the shares of the Series A Preferred Stock so converted. Each share of Series A
Preferred Stock shall be converted into fully paid and nonassessable shares
(calculated to the nearest 1/100 of a share) of Common Stock at the Conversion
Rate in effect on the Conversion Date.

     (c) Exercise of Right to Convert.  To exercise the conversion right
         ----------------------------
provided in Section 5(a), a holder of Series A Preferred Stock shall give
written notice to the Corporation that such holder elects to convert some or all
of its shares. Such notice shall state the name or names (with address or
addresses) in which the certificate or certificates for shares of Common Stock
issuable upon such conversion shall be issued. If less than all Series A
Preferred Stock owned by a holder is to be converted, the notice shall also
specify the number of shares and the certificate numbers thereof which are to be
converted.

     (d) Effectiveness of Conversion; Surrender of Shares. Any conversion of the
         ------------------------------------------------
Series A Preferred Stock into shares of Common Stock shall be deemed to have
been effected at the close of business on the Conversion Date with respect to
such conversion, and at such time, the rights of the holder of the converted
shares of Series A Preferred Stock shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such Conversion shall be deemed to have become the holder
or holders of record of the shares of Common Stock represented thereby. As
promptly as practicable after the Conversion Date and upon receipt of (i) the
certificate or certificates representing the shares to be converted and (ii)
transfer instruments(s) satisfactory to the Corporation and sufficient to
transfer such shares of Series A Preferred Stock to the Corporation free of any
adverse interest, the Corporation shall issue and deliver to the holder of the
shares of Series A Preferred Stock being converted, or on its written order, a
certificate or certificates as it may request for the number of shares of Common
Stock issuable upon the conversion of such shares of Series A Preferred Stock.

     (e) Certificates. In the event that some but not all of the shares of
         ------------
Series A Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Corporation shall execute and deliver
to, or on the order of, such holder, at the expense of the Corporation, a new
certificate representing the number of shares of Series A Preferred Stock which
were not converted.

     (f) Payment of Taxes. The Corporation shall pay all documentary, stamp,
         ----------------
transfer and other taxes (other than taxes on income of the holders of shares of
Series A Preferred Stock) and other governmental charges attributable to the
issuance or delivery of shares of Series A Preferred Stock or of shares of
Common Stock upon conversion of shares of Series A Preferred Stock; provided,
however, that the Corporation shall not be required to pay any taxes payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of the shares of Series
A Preferred Stock in respect of which such shares are being issued.
<PAGE>

     (g)   Fractional Shares. No fractional shares of Common Stock or scrip
           -----------------
shall be issued upon conversion of shares of Series A Preferred Stock. If more
than one share of Series A Preferred Stock shall be surrendered for conversion
at any one time by the same holder, the number of full shares of Common Stock
issuable upon conversion thereof shall be computed on the basis of the aggregate
number of shares of Series A Preferred Stock so surrendered. Instead of any
fractional shares of Common Stock that would otherwise be issuable upon
conversion of any shares of Series A Preferred Stock, the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the Current Market Price on the Conversion Date.

SECTION 6. Conversion Price Adjustments. The Conversion Rate shall be subject
           ----------------------------
to adjustment from time to time as follows:

     (a)   Common Stock Dividends; Stock Splits, etc. If the Corporation shall
           -----------------------------------------
at any time pay a dividend on its Common Stock in Common Stock, subdivide its
outstanding shares of Common Stock into a larger number of shares or combine its
outstanding shares of Common Stock into a smaller number of shares, the
Conversion Rate in effect immediately prior thereto shall be adjusted such that
each share of Series A Preferred Stock shall thereafter be convertible into the
number of shares of Common Stock which the holder of a share of Series A
Preferred Stock would have been entitled to receive after the occurrence of any
of the events described above had such share been converted immediately prior to
the occurrence of such event. An adjustment made pursuant to this Section 6(a)
shall become effective retroactively to the Determination Date in the case of a
dividend and shall become effective on the effective date in the case of a
subdivision or combination.

     (b)   Rights. If the Corporation shall issue rights or warrants to all
           ------
holders of shares of Common Stock for the purpose of entitling them (for a
period not exceeding forty-five (45) days from the date of issuance) to
subscribe for or purchase shares of Common Stock at a price per share less than
the Current Market Price per share of the Common Stock on the Determination Date
for the determination of the stockholders entitled to receive such rights or
warrants, then in each such case unless the holders of shares of the Series A
Preferred Stock shall be permitted to subscribe for or purchase shares of Common
stock on the same basis as though such shares of Series A Preferred Stock had
been converted into shares of Common Stock immediately prior to such
Determination Date, the Conversion Rate in effect immediately prior thereto
shall be adjusted such that the number of shares of Common Stock into which each
share of Series A Preferred Stock shall thereafter be convertible shall be
determined by multiplying the number of shares of Common Stock into which each
share of Series A Preferred Stock was convertible on the date immediately
preceding such Determination Date by a fraction, (A) the numerator of which
shall be the sum of (x) the number of shares of Common Stock outstanding on such
Determination Date and (y) the number of additional shares of Common Stock so
offered for subscription or purchase, and (B) the denominator of which shall be
the sum of (x) the number of shares of Common Stock outstanding on such
Determination Date and (y) the number of shares of Common Stock which the
aggregate offering price of the total number of shares so offered would purchase
at such Current Market Price.
<PAGE>

     (c) Other Distributions. If the Corporation shall fix a Determination Date
         -------------------
with respect to the making of a dividend or other distribution on its Common
Stock (including any such dividend or distribution made in connection with a
consolidation or merger in which the Corporation is the continuing corporation,
but excluding a dividend or distribution (A) referred to in subsection 6(a) or
6(b) hereof, or (B) in connection with a liquidation) consisting of securities
other than Common Stock, evidences of its indebtedness, or assets (excluding any
regular cash dividends paid out of surplus or net profits legally available for
the payment of dividends, but including all other cash dividends and
distributions) (any of the foregoing being hereinafter referred to as "Assets"),
then, in each such case, the Conversion Rate shall be adjusted such that the
number of shares of Common Stock into which each share of Series A Preferred
Stock shall thereafter be convertible shall be determined by multiplying the
number of shares of Common Stock into which each share of Series A Preferred
Stock was theretofore convertible on the date immediately preceding the
Determination Date for the determination of the stockholders entitled to receive
such distribution by a fraction, (A) the numerator of which shall be the Current
Market Price per share of the Common Stock on such Determination Date and (B)
the denominator of which shall be such Current Market Price per share less the
then fair market value (as determined by the Board of Directors of the
Corporation in good faith) of the portion of the cash or other assets, rights,
warrants, evidences of indebtedness or other securities so distributed
applicable to one share of Common Stock. Such adjustment shall become effective
retroactively to immediately after the Determination Date. The reclassification
(including any reclassification upon a merger in which the Corporation is the
continuing corporation) of Common Stock into securities which include both
Common Stock and other securities shall be deemed to involve (i) a distribution
of such securities other than Common Stock to all holders of Common Stock (and
the effective date of such reclassification shall be deemed to be the
"Determination Date" above); and (ii) a subdivision or combination, as the case
may be, of the number of shares of Common Stock outstanding immediately prior to
such reclassification into the number of shares of Common Stock outstanding
immediately thereafter. If such dividend or distribution is not so paid or made,
the Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such Determination Date had not been fixed.

     (d) Common Stock Issued at Less Than Current Market Price.  If the
         -----------------------------------------------------
Corporation shall issue any Common Stock (or securities convertible into or
exercisable for, Common Stock) for a consideration per share less than the
Current Market Price per share of Common Stock on the date of such issuance
(which consideration shall include any compensation received for the issuance of
any securities convertible into or exercisable for such Common Stock), the
Conversion Rate in effect immediately prior to each such issuance shall
immediately (except as provided below) be adjusted such that the number of
shares of Common Stock into which each share of Series A Preferred Stock shall
thereafter be convertible shall be determined by multiplying the number of
shares of Common Stock into which each share of Series A Preferred Stock was
convertible on the date immediately preceding such issue or sale by a fraction,
(A) the denominator of which shall be the sum of (x) the number of shares of
Common Stock outstanding immediately prior to such issue or sale multiplied by
the Current Market Price at the time of such issue or sale plus (y) the
consideration received by the Corporation upon such issue or sale, and (B) the
numerator of which shall be the product derived by multiplying the Current
Market Price at the time of such issue or sale by the number of shares of Common
Stock
<PAGE>

outstanding immediately after such issue or sale; provided, that this subsection
(d) shall not apply to:

     (i)   any transaction or distribution for which an adjustment has been made
pursuant to any other subsection of this Section 6,

     (ii)  the conversion or exchange of securities convertible or exchangeable
for Common Stock or the exercise of rights or warrants issued to the holders of
Common Stock, in each case only if an adjustment was made (or specifically not
required to be made) in connection with the issuance of such securities, rights
or warrants pursuant to any subsection of this Section 6,

     (iii) the conversion of shares of Series A Preferred Stock or Series B
Preferred Stock, and

     (iv)  Common Stock or options to purchase Common Stock issued to directors,
officers or employees of the Corporation and its subsidiaries under bona fide
benefit plans adopted by the Board of Directors and approved by the holders of
Common Stock when required by law.

     (e)   Superseding Adjustment. If, at any time after any adjustment of the
           ----------------------
Conversion Rate shall have been made pursuant to Section 6(b) or Section 6(d) as
the result of any issuance of warrants, options, rights or convertible
securities,

     (A)   such warrants, options or rights, or the right of conversion or
exchange of such convertible securities, shall expire, and all or a portion of
such warrants, options or rights, or the right of conversion or exchange with
respect to all or a portion of such other convertible securities, as the case
may be, shall not have been exercised, or

     (B)   the consideration per share for which shares of Common Stock are
issuable pursuant to such warrants, options or rights, or the terms of such
convertible securities, shall be increased solely by virtue or provisions
therein contained for an automatic increase in such consideration per share upon
the occurrence of a specified date or event,

then such previous adjustment shall be rescinded and annulled and the additional
shares of Common Stock which were deemed to have been issued by virtue of the
computation made in connection with the adjustment so rescinded and annulled
shall no longer be deemed to have been issued by virtue of such computation.
Thereupon, a recomputation shall be made of the effect of such warrants, options
or rights or convertible securities on the basis of:

     (i)   treating the number of additional shares of Common Stock or other
property, if any, theretofore actually issued or issuable pursuant to the
previous exercise of any such warrants, options or rights or any such right of
conversion or exchange, as having been issued on the date or dates of any such
exercise and for the consideration actually received and receivable therefor,
and

     (ii)  treating any such warrants, options or rights or any such convertible
securities which then remain outstanding as having been granted or issued
immediately after the time of
<PAGE>

such increase of the consideration per share for which shares of Common Stock or
other property are issuable under such warrants, options or rights or other
convertible securities;

whereupon a new adjustment of the Conversion Rate shall be made, which new
adjustment shall supersede the previous adjustment so rescinded and annulled.

     (f) Reorganization, Reclassification, Merger Consolidation or Disposition
         ---------------------------------------------------------------------
of Assets. In case the Corporation shall reorganize its capital, reclassify its
- ---------
capital stock, consolidate or merge with or into another corporation (where
there is a change in or distribution with respect to the Common Stock of the
Corporation other than a subdivision, combination or exchange otherwise provided
for herein), or sell, transfer or otherwise dispose of all or substantially all
its property, assets or business to another corporation and, pursuant to the
terms of such reorganization, reclassification, merger, consolidation or
disposition of assets, shares of common stock of the successor or acquiring
corporation, or any cash, shares of stock or other securities or property of any
nature whatsoever (including warrants or other subscription or purchase rights)
in addition to or in lieu of common stock of the successor or acquiring
corporation (herein referred to as "Other Property"), are to be received by or
distributed to the holders of Common Stock of the Corporation, then each holder
of Series A Preferred Stock shall have the right thereafter to receive, upon
conversion of such Series A Preferred Stock, the number of shares of common
stock of the successor or acquiring corporation or of the Corporation, if it is
the surviving corporation, and Other Property receivable upon or as a result of
such reorganization, reclassification, merger, consolidation or disposition of
assets by a holder of the number of shares of Common Stock for which such Series
A Preferred Stock is convertible immediately prior to such event. In case of any
such reorganization reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than the Corporation)
shall expressly assume the due and punctual observance and performance of each
and every term and condition of the Series A Preferred Stock to be performed and
observed by the Corporation and all the obligations and liabilities hereof,
subject to such modifications as may be deemed appropriate (as determined in
good faith by resolution of the Board of Directors of the Corporation) in order
to provide for adjustments of shares of the Common Stock for which Series A
Preferred Stock is convertible which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 6. For purposes of
this Section 6(f) "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event, and any warrants, options
or other rights to subscribe for or purchase any such stock. The foregoing
provisions of this Section 6(t) shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or dispositions of
assets.

     (g) Rounding of Calculations; Minimum Adjustment. All calculations under
         --------------------------------------------
this Section 6 shall be made to the nearest one hundredth (1/100th) of a share.
Any provision hereof to the contrary notwithstanding, no adjustment in the
Conversion Rate shall be made if the amount of such adjustment would require an
increase or decrease of less than 1.0% in the Conversion Rate, but any such
amount shall be carried forward and an adjustment with respect
<PAGE>

thereto shall be made at the time of and together with any subsequent adjustment
which, together with such amount and any other amount or amounts so carried
forward, shall require an increase or decrease of at least 1.0% in the
Conversion Rate.

     (h) Timing of Issuance of Additional Common Stock Upon Certain Adjustments.
         ----------------------------------------------------------------------
If the provisions of this Section 6 shall require that an adjustment shall
become effective immediately after a Determination Date for an event, and prior
to the occurrence of such event conversion rights under Section 5(a) are
exercised, any shares of Common Stock issuable upon exercise by reason of
adjustment shall be deemed the last shares of Common Stock for which such Series
A Preferred Stock is exercised (notwithstanding any provision to the contrary
herein) and such shares or other property shall be held in escrow for the holder
of the Series A Preferred Stock by the Corporation to be issued to such holder
conditioned upon and to the extent that the event actually takes place.
Notwithstanding any other provision to the contrary herein, if the event for
which such record was taken fails to occur or is rescinded, then such escrowed
shares shall be canceled by the Corporation and escrowed property returned.

     (i) Other Action Affecting Common Stock. In case at any time or from time
         -----------------------------------
to time the Corporation shall take any action in respect of its Common Stock,
other than action described in this Section 6, then, unless such action will not
have a material adverse effect upon the rights of the holders of Series A
Preferred Stock, the Conversion Rate or number of shares of other stock for
which Series A~ Preferred Stock is convertible shall be adjusted in such manner
as may be equitable in the circumstances.

     (j) Taking of Record: Stock Transfer Books. In the case of all dividends or
         --------------------------------------
other distributions by the Corporation to the holders of its Common Stock with
respect to which any provision of Section 6 refers to the taking of a record of
such holders, the Corporation will in each such case take such a record and will
take such record as of the close of business on a business day. The Corporation
will not at any time, except upon dissolution, liquidation or winding up of the
Corporation, close its Common Stock transfer books or Series A Preferred Stock
transfer books so as to result in preventing or delaying the conversion or
transfer of any Series A Preferred Stock.

SECTION 7.  Notice.
            ------

     Upon the occurrence of any event which requires an adjustment pursuant to
Section 6, the Corporation shall forthwith prepare a certificate to be executed
by the chief financial officer of the Corporation setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated and specifying the Conversion
Rate after giving effect to such adjustment. The Corporation shall promptly
cause a signed copy of such certificate to be delivered to each holder of Series
A Preferred Stock. The Corporation shall keep at its principal executive office
copies of all such certificates and cause the same to be available for
inspection at said office during normal business hours by any holder of Series A
Preferred Stock or any prospective purchaser of Series A Preferred Stock
designated by any such holder. In addition, holders of Series A Preferred Stock
shall be entitled to the same rights to receive notice of corporate action as
any holder of Common Stock.
<PAGE>

SECTION 8.  Reservation of Shares: Valid Issuance; Approvals.
            ------------------------------------------------

     The Corporation shall (A) reserve at all times so long as any shares of
Series A Preferred Stock remain outstanding, free from preemptive rights, out of
its treasury stock (if applicable) or its authorized but unissued shares of
Common Stock, or both, solely for the purpose of effecting the conversion of the
shares of Series A Preferred Stock, sufficient shares of Common Stock to provide
for the conversion of all outstanding shares of Series A Preferred Stock, (B)
take all necessary action so that all shares of Common Stock that are issued
upon conversion of the shares of the Series A Preferred Stock shall, upon
issuance, be duly and validly issued, fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issuance thereof, and (C) take
no action which will cause a contrary result.

     The Corporation shall use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Corporation to perform
its obligations under these resolutions; provided, however that nothing in this
                                         --------  -------
Section 8 shall require the Corporation to register any class of equity
securities under the Securities Exchange Act of 1934 as amended, or to file any
registration statement under the Securities Act of 1933, as amended, or to
qualify any securities with any state or local governmental authorities in any
jurisdiction. If, and so long as, any Common Stock into which the shares of
Series A Preferred Stock are then convertible is listed on any national
securities exchange, the Corporation shall, if permitted by the rules of such
exchange, list and keep listed on such exchange, upon official notice of
issuance, all shares of such Common Stock issuable upon conversion.

SECTION 9.  No Reissuance of Series A Preferred Stock.
            -----------------------------------------

     No Series A Preferred Stock acquired by the Corporation by reason of
repurchase, conversion or otherwise shall be reissued, and all such shares shall
be canceled, retired and eliminated from the class of Series A Preferred Stock
and shall resume the status of authorized and unissued shares of Preferred
Stock, $.001 par value, as described in the Corporation's Certificate of
Incorporation, as amended.

the extent that Sarnoff owns all of the issued and outstanding shares of Series
A Preferred Stock, Sarnoff shall be entitled to receive, in lieu of the
foregoing the Sarnoff License. For purposes of this Designation, the Sarnoff
License Fair Value shall be equal to, as of the date specified, the fair market
value of the Sarnoff License as mutually agreed upon by the Corporation and the

pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the holder
of the surrendered certificate.

SECTION 14.  Replacement.
             -----------

     Upon receipt of evidence reasonably satisfactory to the Corporation (an
affidavit of the registered holder shall be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing one or
more shares of Series A Preferred Stock and, in the case of any such loss, theft

             SECURITIES AND ANY SECURITIES OR SHARES ISSUED HEREUNDER MAY NOT BE
             SOLD, OFFERED FOR SALE OR TRANSFERRED IN THE ABSENCE OF AN
             EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND ANY APPLICABLE
             STATE SECURITIES LAW OR AN OPINION OF COUNSEL REASONABLY
             SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
             REQUIRED."

SECTION 16.  Exclusion of Other Rights.

                                  DESIGNATION
                                      OF
                     SERIES B CONVERTIBLE PREFERRED STOCK
                                      OF
                           ORCHID BIOCOMPUTER, INC.

SECTION 1.  Designation and Amount.
            ----------------------

          The shares of one series of Preferred Stock created hereunder shall
be designated "Series B Convertible Preferred Stock" (herein referred to as the
"Series B Preferred Stock"), and the number of shares constituting such series
initially shall be 300,000.

SECTION 2.  Dividends.
            ---------

          The Series B Preferred Stock shall not be entitled to any dividends.

SECTION 3.  Liquidation.

          Upon any voluntary or involuntary liquidation, dissolution or winding
up of the Corporation, the holders of the Series B Preferred Stock shall be
entitled to receive out of the assets of the Corporation available for
distribution to stockholders (whether from capital, surplus or earnings), before
any distribution or payment is made upon any Junior Securities, the aggregate
Liquidation Value (as hereinafter defined) of all Series B Preferred Stock
outstanding, and the holders of the Series B Preferred Stock shall not be
entitled to any further distribution. If, upon any such liquidation, dissolution
or winding up of the Corporation, the assets of the Corporation to be
distributed among the holders of the Series B Preferred Stock are insufficient
to permit distribution to such holders of the aggregate amount to which they are
entitled, then the entire assets of the Corporation to be distributed to such
holders shall be distributed ratably among such holders based upon the aggregate
Liquidation Value of the Series B Preferred Stock held by each such holder. The
F Corporation shall mail written notice of such liquidation, dissolution or
winding up, not less than 30 days prior to the distribution date stated therein,
to each record holder of Series B Preferred Stock. Neither the consolidation or
merger of the Corporation into or with any other corporation or corporations,
nor the sale or transfer by the Corporation of all or any part of its assets,
nor the reduction of the capital stock of the Corporation, shall be deemed to be
a liquidation, dissolution or winding up of the Corporation within the meaning
of this Section 3.

SECTION 4.  Voting Rights.
            -------------

          The outstanding shares of Series B Preferred Stock shall at all times
be entitled to a number of votes on any matter put before the stockholders of
the Corporation equal to the number of shares of Common Stock into which such
shares of Series B Preferred Stock are convertible on the record date for
determination of stockholders eligible to vote on such matter, or if no such
record is established, at the date such vote is taken or any written consent of
stockholders is solicited, and shall vote together with the holders of Common
Stock as a single class.
<PAGE>

          The outstanding shares of Series B Preferred Stock shall have all
other voting rights required by law and shall have the following additional
rights:

          (a) No amendment, modification or waiver shall be binding or effective
with respect to any provision of this Designation unless approved by the
affirmative vote of the holders of at least a majority of the outstanding shares
of Series B Preferred Stock voting together as a separate class.

          (b) In addition to any other vote or consent of stockholders 'required
by the Certificate of Incorporation, as amended, or the Bylaws of the
Corporation or by law, the affirmative vote of all the holders of the
outstanding shares of Series B Preferred Stock, voting together as a separate
class, shall be necessary to change the Conversion Rate, or the amount or
priority of any distributions upon liquidation of the Corporation with respect
to, shares of Series B Preferred Stock or to amend this Section 4.

          (c) The affirmative vote of the holders of at least a majority of the
outstanding shares of Series B Preferred Stock voting together as a separate
class shall be necessary to increase the number of authorized shares of
preferred stock or authorize or issue any additional shares of any series of
preferred stock or any shares of capital stock of the Corporation of any class,
or any security or obligations convertible into any capital stock of the
Corporation of any class, in each case ranking on a parity with or senior to the
Series B Preferred Stock as to distribution of assets in liquidation or in right
of payment of dividends.

SECTION 5.  Conversion of the series B Preferred Stock.
            ------------------------------------------

          The Series B Preferred Stock shall be convertible into Common Stock as
follows:

          (a) Optional Conversion. Subject to and upon compliance with the
              -------------------
provisions of this Section 5, each holder of shares of Series B Preferred Stock
shall have the right, at such holder's option, at any time or from time to time,
to convert any of such shares of Series B Preferred Stock into fully paid and
nonassessable shares of Common Stock upon the terms hereinafter set forth. Each
share of Series B Preferred Stock shall be converted into fully paid and
nonassessable shares (calculated to the nearest 1/100 of a share)of Common Stock
at the Conversion Rate in effect on the Conversion Date.

          (b) Automatic Conversion. in the event that, at any time while any of
              --------------------
the Series B Preferred Stock shall be outstanding, the Corporation shall
consummate an underwritten public offering on a firm commitment basis pursuant
to an effective registration statement under the Securities Act of 1933, as
amended, covering the offer and sale of Common Stock providing aggregate net
proceeds to the Corporation equal to at least $15,000,000 (a "Qualifying Public
Offering"), then all outstanding shares of Series B Preferred Stock shall,
automatically and without further action on the part of the holders of the
Series B Preferred Stock, be converted into shares of Common Stock with the same
effect as if the certificates evidencing such shares had been surrendered for
conversion, such conversion to be effective simultaneously with the closing of
such public offering; provided, however, that certificates evidencing the shares
of Common Stock issuable upon such conversion shall not be issued except on
surrender of the certificates for the shares of the Series B Preferred Stock so
converted. Each share of Series B
<PAGE>

Preferred Stock shall be converted into fully paid and nonassessable shares
(calculated to the nearest 1/100 of a share) of Common Stock at the Conversion
Rate in effect on the Conversion Date.

          (c) Exercise of Right to Convert. To exercise the conversion right
              ----------------------------
provided in Section 5(a), a holder of Series B Preferred Stock shall give
written notice to the Corporation that such holder elects to convert some or all
of its shares. Such notice shall state the name or names (with address or
addresses) in. which the certificate or certificates for shares of Common Stock
issuable upon such conversion shall be issued. If less than all Series B
Preferred Stock owned by a holder is to be converted, the notice shall also
specify the number of shares and the certificate numbers thereof which are to be
converted.

          (d) Effectiveness of Conversion: Surrender of Shares. Any conversion
              ------------------------------------------------
of the Series B Preferred Stock into shares of 4 Common Stock shall be deemed to
have been effected at the close of business on the Conversion Date with respect
to such conversion, and at such time, the rights of the holder of the converted
shares of Series B Preferred Stock shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares of Common Stock represented thereby. As
promptly as practicable after the Conversion Date and upon receipt of (i) the
certificate or certificates - - representing the shares to be converted and (ii)
transfer instruments(s) satisfactory to the Corporation and sufficient to
transfer such shares of Series B Preferred Stock to the Corporation free of any
adverse interest, the Corporation shall issue and deliver to the holder of the
shares of Series B Preferred Stock being converted, or on its written order, a
certificate or certificates as it may request for the number of shares of Common
Stock issuable upon the conversion of such shares of Series B Preferred Stock.

          (e) Certificates. In the event that some but not all of the shares of
              ------------
Series B Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Corporation shall execute and deliver
to, or on the order of, such holder \\1\\ at the expense of the Corporation, a
new certificate representing the number of shares of Series B Preferred Stock
which were not converted.

          (f) Payment of Taxes. The Corporation shall pay all documentary,
              ----------------
stamp, transfer and other taxes (other than taxes on income of the holders of
shares of Series B Preferred Stock) and other governmental charges attributable
to the issuance or delivery of shares of Series B Preferred Stock or of shares
of Common Stock upon conversion of shares of Series B Preferred Stock; provided,
however, that the Corporation shall not be required to pay any taxes payable in
respect of any transfer involved in the issuance or delivery of any certificate
f or such shares in a name other than that of the holder of the shares of Series
B Preferred Stock in respect of which such shares are being issued.

          (g) Fractional Shares. No fractional shares of Common Stock or scrip
              -----------------
shall be issued upon conversion of shares of Series B Preferred Stock. If more
than one share of Series B Preferred Stock shall be surrendered for conversion
at any one time by the same holder, the number of full shares of Common Stock
issuable upon conversion thereof shall be computed on the basis of the aggregate
number of shares of Series B Preferred Stock so surrendered. Instead
<PAGE>

of any fractional shares of Common Stock that would otherwise be issuable upon
conversion of any shares of Series B Preferred Stock, the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the Current Market Price on the Conversion Date.

SECTION 6.  Conversion Price Adjustments. The Conversion Rate shall be subject
            ----------------------------
to adjustment from time to time as follows:

          (a) Common Stock Dividends; Stock Splits, etc. If the Corporation
              ------------------------------------------
shall at any time pay a dividend on its Common Stock in Common Stock, subdivide
its outstanding shares of Common Stock into a larger number of shares or combine
its outstanding shares of Common Stock into a smaller number of shares, the
Conversion Rate in effect immediately prior thereto shall be adjusted such K
that each share of Series B Preferred Stock shall thereafter be convertible into
the number of shares of Common Stock which the holder of a share of Series B
Preferred Stock would have been entitled to receive after the occurrence of any
of the events described above had such share been converted immediately prior to
the occurrence of such event. An adjustment made pursuant to this Section 6(a)
shall become effective retroactively to the Determination Date in the case of a
dividend and shall become effective on the effective date in the case of a
Subdivision or combination.

          (b) Rights.  If the Corporation shall issue rights or warrants to all
              ------
holders of shares of Common Stock for the purpose of entitling them (for a
period not exceeding forty-five (45) days from the date of issuance) to
subscribe for or purchase shares of Common Stock at a price per share less than
the Current Market Price per share of the Common Stock on the Determination Date
for the determination of the stockholders entitled to receive such rights or
warrants, then in each such case unless the holders of shares of the Series B
Preferred Stock shall be permitted to subscribe for or purchase shares of Common
stock on the same basis as though such shares of Series B Preferred Stock had
been converted into shares of Common Stock immediately prior to such
Determination Date, the Conversion Rate in effect immediately prior thereto
shall be adjusted such that the number of shares of Common Stock into which each
share of Series B Preferred Stock shall thereafter be convertible shall be
determined by multiplying the number of shares of Common Stock into which each
share of Series B Preferred Stock was convertible on the date immediately
preceding such Determination Date by a fraction, (A) the numerator of which
shall be the sum of (x) the number of shares of Common Stock outstanding on such
Determination Date and (y) the number of additional shares of Common Stock so
offered for Subscription or purchase, and (B) the denominator of which shall be
the sum of (x) the number of shares of Common Stock outstanding on such
Determination Date and (y) the number of shares of Common Stock which the
aggregate offering price of the total number of shares so offered would purchase
at such Current Market Price.

          (c) Other Distributions. If the Corporation shall fix a Determination
              -------------------
Date with respect to the making of a dividend or other distribution on its
Common Stock (including any such dividend or distribution made in connection
with a consolidation or merger in which the Corporation is the continuing
corporation, but excluding a dividend or distribution (A) referred to in
subsection 6(a) or 6(b) hereof, or (B) in connection with a liquidation)
consisting of securities other than Common Stock, evidences of its indebtedness,
or assets (excluding any regular cash dividends paid out of surplus or net
profits legally available for the payment of dividends, but
<PAGE>

including all other cash dividends and distributions) (any of the foregoing
being hereinafter referred to as "Assets") then, in each such case, the
Conversion Rate shall be adjusted such that the number of shares of Common Stock
into which each share of Series B Preferred Stock shall thereafter be
convertible shall be determined by multiplying the number of shares of Common
Stock into which each share of Series 3 Preferred Stock was theretofore
convertible on the date immediately preceding the Determination Date for the
determination of the stockholders entitled to receive such distribution by a
fraction, (A) the numerator of which shall be the Current Market Price per share
of the Common Stock on such Determination Date and (B) the denominator of which
shall be such Current Market Price per share less the then fair market value (as
determined by the Board of Directors of the Corporation in good faith) of the
portion of the cash or other assets, rights, warrants, evidences of indebtedness
or other securities so distributed applicable to one share of Common Stock. Such
adjustment shall become effective retroactively to immediately after the
Determination Date. The reclassification (including any reclassification upon a
merger in which the Corporation is the continuing corporation) of Common Stock
into securities which include both Common Stock and other securities shall be
deemed to involve a distribution of such securities other than Common Stock to
all holders of Common Stock (and the effective date of such reclassification
shall be deemed to be the "Determination Date" above); and (ii) a subdivision or
combination, as the case may be, of the number of shares of Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Common Stock outstanding immediately thereafter. If such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such Determination
Date had not been fixed.

          (d)   Common Stock Issued at Less Than Current Market. If the
                -----------------------------------------------
Corporation shall issue any Common Stock (or securities convertible into or
exercisable for, Common Stock) for a consideration per share less than the
Current Market Price per share of Common Stock on the date of such issuance
(which consideration shall include any compensation received for the issuance of
any securities convertible into or exercisable for such Common Stock), the
Conversion Rate in effect immediately prior to each such issuance shall
immediately (except as provided below) be adjusted such that the number of
shares of Common Stock into which each share of Series B Preferred Stock shall
thereafter be convertible shall be determined by multiplying the number of
shares of Common Stock into which each share of Series B Preferred Stock was
convertible on the date immediately F preceding such issue or sale by a
fraction, (A) the denominator of which shall be the sum of (x) the number of
shares of Common Stock outstanding immediately prior to such issue or sale
multiplied by the Current Market Price at the time of such issue or sale plus
(y) the consideration received by the Corporation upon such issue or sale, and
(B) the numerator of which shall be the product derived by multiplying the
Current Market Price at the tame of such issue or sale by the number of shares
of Common Stock outstanding immediately after such issue or sale; provided, that
this subsection (d) shall not apply to:

          (i)   any transaction or distribution for which an adjustment has been
                made pursuant to any other subsection of this Section 6,

          (ii)  the conversion or exchange of securities convertible or
                exchangeable for Common Stock or the exercise of rights or
                warrants issued to the holders of Common Stock, in each case
                only if an adjustment was made (or
<PAGE>

                specifically not required to be made) in connection with the
                issuance of such securities, rights or warrants pursuant to any
                subsection of this Section 6,

          (iii) the conversion of shares of Series A Preferred Stock or Series B
                Preferred Stock, and

          (iv)  Common Stock or options to purchase Common Stock issued to
                directors, officers or employees of the Corporation and its
                subsidiaries under bona fide benefit plans adopted by the Board
                of Directors and approved by the holders of Common Stock when
                required by law.

          (e)   Superseding Adjustment. If, at any time after any adjustment of
                ----------------------
the Conversion Rate shall have been made pursuant to Section 6(b) or Section
6(d) as the result of any issuance of warrants, options, rights or convertible
securities,

          (A)   such warrants, options or rights, or the right of conversion or
                exchange of such convertible securities, shall expire, and all
                or a portion of such warrants, options or rights, or the right
                of conversion or exchange with respect to all or a portion of
                such other convertible securities, as the case may be, shall not
                have been exercised, or

          (B)   the consideration per share for which shares of common Stock are
                issuable pursuant to such warrants, options or rights, or the
                terms of such convertible securities, shall be increased solely
                by virtue or provisions therein contained for an automatic
                increase in such consideration per share upon the occurrence of
                a specified date or event,

then such previous adjustment shall be rescinded and annulled and the additional
shares of Common Stock which were deemed to have been issued by virtue of the
computation made in connection with the adjustment so rescinded and annulled
shall no longer be deemed to have been issued by virtue of such computation.
Thereupon, a recomputation shall be made of the effect of such warrants, options
or rights or convertible securities on the basis of:

          (i)   treating the number of additional shares of Common Stock or
                other property, if any, theretofore actually issued or issuable
                pursuant to the previous exercise of any such warrants, options
                or rights or any such right of conversion or exchange, as having
                been issued on the date or dates of any such exercise and for
                the consideration actually received and receivable therefor, and

          (ii)  treating any such warrants, options or rights or any such
                convertible securities which then remain outstanding as having
                been granted or issued immediately after the time of such
                increase of the consideration per share for which shares of
                Common Stock or other property are issuable under such warrants,
                options or rights or other convertible securities;
<PAGE>

whereupon a new adjustment of the Conversion Rate shall be made, which new
adjustment shall supersede the previous adjustment so rescinded and annulled.

          (f) Reorganization, Reclassification, Merger. Consolidation or
              ----------------------------------------------------------
Disposition of Assets. In case the Corporation shall reorganize its capital,
- ---------------------
reclassify its capital stock, consolidate or merge with or into another
corporation (where there is a change in or distribution with respect to the
Common Stock of the Corporation other than a subdivision, combination or
exchange otherwise provided for herein), or sell, transfer or otherwise dispose
of all or substantially all its property, assets or business to another
Corporation and, pursuant to the terms of such reorganization, reclassification,
merger, consolidation or disposition of assets, shares of common stock of the
successor or acquiring corporation, or any cash, shares of stock or other
securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of
the successor or acquiring corporation (herein referred to as "Other Property"),
are to be received by or distributed to the holders of Common Stock of the
Corporation, then each holder of Series B Preferred Stock shall have the right
thereafter to receive, upon conversion of such Series B Preferred Stock, the
number of shares of common stock of the successor or acquiring corporation or of
the Corporation, if it is the surviving corporation, and Other Property
receivable upon or as a result of such reorganization, reclassification \\1\\
merger, consolidation or disposition of assets by a holder of the number of
shares of Common Stock for which such Series B Preferred Stock is convertible
immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Corporation) shall expressly assume
the due and punctual observance and performance of each and every term and
condition of the Series B Preferred Stock to be performed and observed by the
Corporation and all the obligations and liabilities hereof, subject to such
modifications as may be deemed appropriate (as determined in good faith by
resolution of the Board of Directors of the Corporation) in order to provide for
adjustments of shares of the Common Stock for which Series B Preferred Stock is
convertible which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 6. For purposes of this Section 6(f)
"common stock of the successor or acquiring corporation" shall include stock of
such corporation of any class which is not preferred as to dividends or assets
over any other class of stock of such corporation and which is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event, and any warrants, options or other rights to
subscribe for or purchase any such stock. The foregoing provisions of this
Section 6(f) shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or dispositions of assets.

          (g) Rounding of Calculations: Minimum Adjustment. All calculations
              --------------------------------------------
under this Section 6 shall be made to the nearest one hundredth (1/100th) of a
share. Any provision hereof to the contrary notwithstanding, no adjustment in
the Conversion Rate shall be made if the amount of such adjustment would require
an increase or decrease of less than 1.0% in the Conversion Rate, but any such
amount shall be carried forward and an adjustment with respect thereto shall be
made at the time of and together with any subsequent adjustment which, together
with such amount and any other amount or amounts so carried forward, shall
require an increase or decrease of at least 1.0% in the Conversion Rate.
<PAGE>

          (h) Timing of Issuance of Additional Common Stock Upon Certain
              ----------------------------------------------------------
Adjustments. If the provisions of this Section 6 shall require that an
- -----------
adjustment shall become effective immediately after a Determination Date for an
event, and prior to the occurrence of such event conversion rights under Section
5(a) are exercised, any shares of Common Stock issuable upon exercise by reason
of adjustment shall be deemed the last shares of Common Stock for which such
Series B Preferred Stock is exercised 4 F (notwithstanding any provision to the
contrary herein) and such shares or other property shall be held in escrow for
the holder of the Series B Preferred Stock by the Corporation to be issued to
such holder conditioned upon and to the extent that the event actually takes
place. Notwithstanding any other provision to the contrary herein, if the event
for which such record was taken fails to occur or is rescinded, then such
escrowed shares shall be canceled by the Corporation and escrowed property
returned.

          (i) Other Action Affecting Common Stock. In case at any time or from
              -----------------------------------
time to time the Corporation shall take any action in respect of its Common
Stock, other than action described in this Section 6, then, unless such action
will not have a material adverse effect upon the rights of the holders of Series
B Preferred Stock, the Conversion Rate or number of shares of other stock for
which Series B Preferred Stock is convertible shall be adjusted in such manner
as may be equitable in the circumstances.

          (j) Taking of Record; Stock Transfer Books. In the case of all
              --------------------------------------
dividends or other distributions by the Corporation to the holders of its Common
Stock with respect to which any provision of Section 6 refers to the taking of a
record of such holders, the Corporation will in each such case take such a
record arid will take such record as of the close of business on a business day.
The Corporation will not at any time, except upon dissolution, liquidation or
winding up of the Corporation, close its Common Stock transfer books or Series B
Preferred Stock transfer books so as to result in preventing or delaying the
conversion or transfer of any Series B Preferred Stock.

SECTION 7.  Notice.

Stock will participate equally with each other ratably per share (calculated as
provided in Section A.3(b) hereof).
<PAGE>

          A.3(b) In connection with any dividend declared or paid hereunder,
each share of Series C Stock shall be deemed to be that number of shares
(including fractional shares) of Common Stock into which it is then convertible,
rounded up to the nearest one-tenth of a share. No fractional shares of capital
stock shall be issued as a dividend hereunder. The Corporation shall pay a cash
adjustment for any such fractional interest in an amount equal to the fair
market value thereof on the last Business Day (as defined in Section A.8 hereof)
immediately preceding the date for payment of dividends, as determined by the
Board of Directors in good faith.

     Section A.4 Liquidation Rights.
                 ------------------

          A.4(a) With respect to rights on Liquidation (as defined in Section
A.4(b) hereof), the Series C Stock shall rank equally with each other and with
each other holder of shares of Series A Stock and of shares of Series B Stock
and senior and prior to the Corporation's Common Stock and to all other classes
or series of stock issued by the Corporation, except as otherwise approved by
the affirmative vote or consent of the holders of Series C Stock pursuant to
Section A.6(c) hereof.

          A.4(b) Subject to Section A.4(a) above, in the event of any
liquidation, dissolution or winding-up of the affairs of the Corporation
(collectively, a "Liquidation"), the holders of shares of Series C Stock then
outstanding (the "Series C Stockholders") shall be entitled to receive out of
the assets of the Corporation legally available for distribution to its
stockholders, whether from capital, surplus or earnings before any payment shall
be made to the holders of Common Stock or any other class or series of stock
ranking on Liquidation junior to such Series C Stock, an amount per share equal
to the Original Purchase Price (as defined in Section A.8 hereof), plus, in each
case, an amount equal to any accrued and declared but unpaid dividends thereon
pursuant to Section A.3(a) hereof.

          A.4(c) Subject to Section A.4(a) above, if, upon any Liquidation, the
assets of the Corporation available for distribution to its stockholders shall
be insufficient to pay the Series C Stockholders the full amount as to which
each of them shall be entitled pursuant to Section A.4(b), then the Series C
Stockholders shall first share ratably in any distribution of assets according
to the respective amounts which would be payable to them in respect of the
shares held upon such distribution if all amounts payable on or with respect to
such shares were paid in full. For purposes of calculating the amount of any
payment to be paid upon any such Liquidation, each share of Series C Stock shall
be deemed to be that number of shares (including fractional shares) of Common
Stock into which it is then convertible, rounded to the nearest one-tenth of a
share.

          A.4(d) In the event of any Liquidation, after payment shall have been
made to the Series C Stockholders of the full amount to which they shall be
entitled pursuant to Section A.4(b), with respect to each other class or series
of capital stock (other than Common Stock) ranking on Liquidation junior to such
Series C Stock (in descending order of seniority), the Series C Stockholders,
as a class, shall be entitled to receive an amount equal (and in like kind) to
the aggregate preferential amount fixed for each such junior class or series of
capital stock, which amount shall be distributed among the Series C Stockholders
in an equal amount per share of the Series C Stock then outstanding. If, upon
any Liquidation, the assets of the Corporation available for distribution to its
stockholders shall be insufficient to pay the Series C Stockholders
<PAGE>

and a class or series of capital stock (other than the Common Stock) junior to
the Series C Stock the full amounts to which they shall be entitled pursuant to
the next preceding sentence, the holders of the Series C Stock and such other
class or series of capital stock shall share ratably in any distribution of
assets according to the respective preferential amounts fixed for the Series C
Stock (pursuant to Section A.4(b)) and such junior class or series of capital
stock which would be payable in respect of the shares held by them upon such
distribution if all amounts payable on or with respect to such shares were paid
in full.

          A.4(e)     In the event of any Liquidation, after payment shall have
been made to the Series C Stockholders of the full amount to which they shall be
entitled as aforesaid, with respect to the Common Stock the Series C
Stockholders as a class shall be entitled to share ratably (calculated with
respect to such Series C Stock as provided in the next sentence) with the Common
Stockholders in all remaining assets of the Corporation available for
distribution to its stockholders. For purposes of calculating the amount of any
payment to be paid upon any such Liquidation, each share of such Series C Stock
shall be deemed to be that number of shares (including fractional shares) of
Common Stock into which it is then convertible, rounded to the nearest one-tenth
of a share.

          A.4(f)(i)   In the event of and simultaneously with the closing of an
Event of Sale (as hereinafter defined), the Corporation shall (unless waived
pursuant to Section A.4(f)(v) or otherwise prevented by law) redeem all of the
shares of Series C Stock then outstanding for a cash amount per share determined
as set forth herein (the "Special Liquidation Price," said redemption being
referred to herein as a "Special Liquidation"). For all purposes of this Section
A.4(f), the Special Liquidation Price shall be equal to that amount per share
which would be received by each Series C Stockholder if, in connection with an
Event of Sale, all consideration paid in exchange for the assets or the shares
of capital stock (as the case may be) of the Corporation were actually paid to
and received by the Corporation and the Corporation were immediately thereafter
liquidated and its assets distributed pursuant to Section A.4(a) through (e)
hereof. To the extent that one or more redemptions (as described in Section A.5
hereof) and/or Special Liquidations are occurring concurrently, the Special
Liquidation under this Section A.4(f) shall be deemed to occur first. The date
upon which the Special Liquidation shall occur is sometimes referred to herein
as the "Special Liquidation Date".

          A.4(f)(ii)  At any time on or after the Special Liquidation Date, a
Series C Stockholder shall be entitled to receive the Special Liquidation Price
for each such share of Series C Stock owned by such holder. Subject to the
provisions of Section A.4(f)(iii) hereof, payment of the Special Liquidation
Price will be made upon actual delivery to the Corporation or its transfer agent
of the certificate representing such shares of Series C Stock.

          A.4(f)(iii) If on the Special Liquidation Date less than all the
shares of Series C Stock then outstanding may be legally redeemed by the
Corporation, the Special Liquidation shall be pro rata with respect to such
                                              --- ----
Series C Stock based upon the number of outstanding shares of Series C Stock
then owned by each holder thereof.

          A.4(f)(iv)  On and after any Special Liquidation rate, all rights in
respect of the shares of Series C Stock to be redeemed shall cease and terminate
except the right to receive the applicable Special Liquidation Price as provided
herein, and such shares of Series C Stock shall
<PAGE>

no longer be deemed to be outstanding, whether or not the certificates
representing such shares of Series C Stock have been received by the
Corporation; provided, however, that, if the Corporation defaults in the payment
             --------  -------
of the Special Liquidation Price with respect to any Series C Stock, the rights
of the holder(s) thereof with respect to such shares of Series C Stock shall
continue until the Corporation cures such default.

          A.4(f)(v)   Anything contained herein to the contrary notwithstanding,
the provisions of this Section A.4(f) may be waived by the holders of 66 2/3% in
voting power of the share of Series C Stock then outstanding, by delivery of
written notice of waiver to the Corporation prior to the closing of any Event of
Sale, in which event the Corporation shall not redeem any shares of Series C
Stock pursuant to this Section A.4(f).

          A.4(f)(vi)  Any notice required to he given to the holders of shares
of Series C Stock pursuant to Section A.7(f) hereof in connection with an Event
of Sale shall include a statement by the Corporation of (A) the Special
Liquidation Price which each Series C Stockholder shall be entitled to receive
upon the occurrence of a Special Liquidation under this Section A.4(f) and (B)
the extent to which the Corporation will, if at all, be legally prohibited from
paying each holder of Series C Stock the Special Liquidation Price.

          A.4(f)(vii) For purposes of this Section A.4(f), an "Event of Sale"
shall mean (A) the merger or consolidation of the Corporation into or with
another corporation, partnership, joint venture, trust or other entity, or the
merger or consolidation of any corporation into or with the Corporation (in
which consolidation or merger the stockholders of the Corporation receive
distributions of cash or securities as a result of such consolidation or merger
in complete exchange for their shares of capital stock of the Corporation), or
(B) the sale or other disposition of all or substantially all the assets of the
Corporation, unless, upon consummation of such merger, consolidation or sale of
assets, the holders of voting securities of the Corporation immediately prior to
such transaction continue to own directly or indirectly not less than a majority
of the voting power of the surviving corporation.


     Section A.5  Redemption.
                  ----------

     A.5(a)(i) Subject to Section A.5(a)(v) of this Section A.5, on or after
December ____, 2002, the Corporation shall (unless otherwise prevented by law)
at the request of holders of not less than 66 2/3% in voting power of the then
outstanding shares of Series C Stock (each, a "Requesting Preferred Stockholder"
and collectively, the "Requesting Preferred Stockholders") redeem all (but not
less than all) of the outstanding Series C Stock owned by such Requesting
Preferred Stockholders. The redemption price per share (the "Redemption
Payment") shall be equal to the Original Purchase Price for each Series C Stock,
which amounts shall be paid by the Corporation in three equal annual
installments, each of which redemption payment installments shall be increased
by an amount equal to any accrued but unpaid dividends thereon to the respective
date of such redemption installment payment (each hereinafter referred to as a
"Redemption Date"), with the first such redemption to be upon not less than 40
days prior written notice to the Corporation in accordance with Section A.5(a)
of this Article.
<PAGE>

     A.5(a)(iii) On and after the respective Redemption Date all rights of any
Requesting Preferred Stockholder with respect to the Series C Stock to be
redeemed on such date as applicable, owned by such Requesting Preferred
Stockholder, except the right to receive the Redemption Payment as provided
herein, shall cease, and such shares shall no longer be deemed to be
outstanding, whether or not the Corporation has received the certificates
representing such shares; provided, however, that if the Corporation defaults in
                          --------  -------
the payment of the Redemption Payment the rights of the Requesting Preferred
Stockholder shall continue until the Corporation cures such default.

     A.5(a)(iii) Any Requesting Preferred Stockholder shall send notice of its
redemption request (the "Redemption Notices) pursuant to this Section A.5(a), by
first-class, certified mail, return receipt requested, postage prepaid to the
Corporation at its principal place of business. At any time on or after a
Redemption Date, the Requesting Preferred Stockholders, with respect to the
shares of Series C Stock requested by such Requesting Preferred Stockholders to
be redeemed on a Redemption Date in accordance with this Section A.5(a) shall be
entitled to receive the Redemption Payment in three equal installments, the
first of which installments shall be made upon actual delivery to the
Corporation or its transfer agent of the certificate or certificates
representing the shares of Series C Stock to be redeemed.

     A.5(a)(iv)  If the assets of the Corporation available for any redemption
pursuant to this Section A.5(a) shall be insufficient to pay, or if the
Corporation upon any redemption shall be prevented by law from paying, the
aggregate of the Redemption Payments owing on such Redemption Date, then (i) the
Requesting Preferred Stockholders shall share ratably in any such redemption
according to the respective amounts which would be payable in respect of such
shares if the Redemption Payment installments then payable with respect to the
Requesting Preferred Stockholders were paid in full, and any such Redemption
Payment installment with respect to the Requesting Preferred Stockholders shall
be made in full before any payment shall be made to the holders of any stock
ranking on redemption junior to the Series C Stock (with respect to rights to
redemption, the Series C Stock shall be pari passu and shall rank prior to the
                                        ---- -----
Common Stock). At any time thereafter when additional funds of the Corporation
are legally available for the redemption of any Series C Stock of the Requesting
Preferred Stockholders not redeemed on the Redemption Date, such funds will
immediately be used to redeem the balance of the Series C Stock of the
Requesting Preferred Stockholders which the Corporation became obligated to
redeem on such Redemption Date, but which it has not so redeemed, prior to the
redemption of any other shares of Preferred Stock of the Corporation.

     A.5(a)(v)   Anything contained in this Section A.5(a) to the contrary
notwithstanding, the holders of Series C Stock shall have the right, exercisable
at any time up to the fifth Business Day prior to the close of business on a
Redemption Date (unless the Corporation shall default in, or be legally
prohibited from, paying the installment payment of the Redemption Price as
herein provided, in which event such right shall be exercisable until such
default is cured), to convert all or any part of such shares requested by such
holder to be redeemed as herein provided into shares of Common Stock pursuant to
Section A.7 of this Article.  If, and to the extent, any Series C Stock so
entitled to redemption are converted into shares of Common Stock by the holders
thereof prior to the close of business on such Redemption Date, the total number
of Series C Stock otherwise to be redeemed on such Redemption Date shall be
reduced by the number of Series C Stock so converted.
<PAGE>

     A.5(a)(vi)  Shares of Series C Stock are not subject to or entitled to the
benefit of a sinking fund.

     Section A.6  Voting.
                  ------

          A.6(a)     In addition to any other rights provided for herein or by
law, the Series C Stockholders shall be entitled to vote on all matters as to
which Common Stockholders shall be entitled to vote, in the same manner and with
the same effect as such Common Stockholders. In any such vote, each share of
Series C Stock shall entitle the holder thereof to the number of votes per share
that equals the number of shares of Common Stock (including fractional shares)
into which each such share of Series C Stock is then convertible, rounded up to
the nearest one-tenth of a share.

          A.6(b)(i)  In addition to the rights specified in Section A.6(a), the
holders of a majority in voting power of the Series C Stock, voting as a
separate class, shall have the exclusive right to elect two directors to the
board of Directors of the Corporation (the "Series C Preferred Directors"). In
any election of Series C Preferred Directors pursuant to this Section A.6(b),
each Series C Stockholder shall be entitled to one vote for each share of the
Series C Stock held, and no Series C Stockholder shall be entitled to cumulate
its votes by giving one candidate more than one vote per share. The exclusive
voting right of the Series C Stockholders, contained in this Section A.6(b), may
be exercised at a special meeting of the Series C Stockholders called as
provided in accordance with the By-laws of the Corporation, at any annual or
special meeting of the stockholders of the Corporation, or by written consent
of such Series C Stockholders in lieu of a meeting. The Series C Preferred
Directors elected pursuant to this Section A.6(b) shall serve from the date of
their election and qualification until their successors have been duly elected
and qualified.

          A.6(b)(ii) A vacancy in the directorships to be elected by the Series
C Stockholders (including any vacancy created on account of an increase in the
number of directors on the Board of Directors), pursuant to Section A.6(b)(i),
may be failed only by a vote at a meeting called in accordance with the By-laws
of the Corporation or written consent in lieu of such meeting of (A) the holders
of at least a majority in voting power of such Series C Stock or (B) the
remaining director(s) elected by the Series C Stockholders.

          A.6(c)     The Corporation shall not, without the affirmative approval
of the holders of shares representing at least sixty-six and two-thirds percent
(66 2/3%) of the voting power of the Series C Stock then outstanding (determined
as set forth in the second sentence of Section A6(a) hereof), acting separately
from the holders of Common Stock or any other securities of the Corporation
given by written consent in lieu of a meeting or by vote at a meeting called for
such purpose, for which meeting or approval by written consent timely and
specific notice (a "Notice") shall have been given to each holder of such Series
C Stock, in the manner provided in the By-laws of the Corporation: (i) sell,
abandon, transfer, lease or otherwise dispose of all or substantially all of its
properties or assets or assets or properties in a single or series of related
transactions in excess of 10% of the then net worth of the Corporation, (ii)
except as otherwise required by this Certificate of Designation, declare or pay
any dividend or make any distribution with respect to shares of its capital
stock (whether in cash, shares of capital stock or other securities or
property); (iii) except as otherwise required by this Certificate of Designation
or in
<PAGE>

any agreement approved by the Board of Directors with an officer, director,
employee or consultant providing for the repurchase of any of its capital stock
owned by such officer, director, employee or consultant at the option of the
Corporation, make any payment on account of the purchase, redemption or other
retirement of any share of capital stock of the Corporation, or distribute to
Common Stockholders shares of the Corporation's capital stock (other than Common
Stock) or other securities of other entities, evidences of indebtedness issued
by the Corporation or other entities, or other assets or options or rights; (iv)
merge or consolidate with or into, or permit any subsidiary to merge or
consolidate with or into, any other corporation, corporations or other entity or
entities; (v) voluntarily dissolve, liquidate or wind-up or carry out any
partial liquidation or distribution or transaction in the nature of a partial
liquidation or distribution; (vi) in any manner alter or change the
designations, powers, preferences, rights, qualifications, limitations or
restrictions or the Series C Stock; (vii) take any action to cause any
amendment, alteration or repeal of any of the provisions of Certificate of
Designation or the By-laws of the Corporation, which amendment, alteration or
repeal adversely affects the powers, preferences or rights pertaining to the
Series C Stock; (viii) authorize, designate, create, issue or agree to issue any
shares of Preferred Stock or other capital stock of the Corporation (including,
without limitation, additional shares of Series C Stock) ranking senior to or
pari passu with the Series C Stock with respect to dividends or liquidation; or
(ix) amend or modify any stock option plan of the Corporation or any stock
option agreement or restricted stock purchase agreement or stock restriction
agreement entered into between the Corporation and its employees, officers,
directors, consultants, contractors and/or any other signatory thereto
(including, without limitation, to accelerate the vesting schedule or exercise
date or dates of any such option or in any stock option agreement or waive or
modify the Corporation's repurchase rights with respect to any shares of the
Corporation's stock issuable pursuant to any restricted stock purchase agreement
or stock restriction agreement) except for immaterial changes either made
thereto from time to time by officers of the Corporation or approved in writing
by both of the Series C Preferred Directors.

     Section A.7  Conversion.
                  ----------

          Section A.7(a)(i) Any Series C Stockholder shall have the right, at
any time or from time to time, to convert any or all of its Series C Stock into
that number of fully paid and nonassessable shares of Common Stock for each
share of Series C Stock so converted equal to the quotient of the Original
Purchase Price for such share divided by the Conversion Price for such share (as
defined in Section A.7(d) hereof), as last adjusted and then in effect, rounded
up to the nearest one-tenth of a share; provided, however, that cash shall be
                                        --------  -------
paid in lieu of the issuance of fractional shares of Common Stock, as provided
in Section A.7(c)(ii) hereof.

          A.7(a)(ii) Any Series C Stockholder who exercises the right to convert
shares of Series C Stock into shares of Common Stock, pursuant to this Section
A.7. shall be entitled to payment of all declared but unpaid dividends payable
with respect to such Series C Stock pursuant to Section A.3(a) herein, up to and
including the Conversion Date (as defined in Section A.7(b)(ii) hereof).

          A.7(b)(i) Any Series C Stockholder may exercise the right to convert
such shares into Common Stock pursuant to this Section A.7 by delivering to the
Corporation during regular business hours, at the office of the Corporation or
any transfer agent of the Corporation or at
<PAGE>

such other place as may be designated by the Corporation, the certificate or
certificates for the shares to be converted (the "Series C Preferred
Certificate"), duly endorsed or assigned in blank to the Corporation (if
required by it).

          A.7(b)(ii)   Each Series C Preferred Certificate shall be accompanied
by written notice stating that such holder elects to convert such shares and
stating the name or names (with address) in which the certificate or
certificates for the shares of Common Stock (the "Common Certificate") are to be
issued. Such conversion shall be deemed to have been effected on the date when
such delivery is made, and such date is referred to herein as "Conversion Date".

          A.7(b)(iii)  As promptly as practicable thereafter, the Corporation
shall issue and deliver to or upon the written order of such holder, at the
place designated by such holder, a certificate or certificates for the number
of full shares of Common Stock to which such holder is entitled and a check or
cash in respect of any fractional interest in any shares of Common Stock, as
provided in Section A.7(c)(ii) hereof, payable with respect to the shares so
converted up to and including the Conversion Date.

          A.7(b)(iv)   The person in whose name the certificate or certificates
for Common Stock are to be issued shall be deemed to have become a holder of
record of Common Stock on the applicable Conversion Date, unless the transfer
books of the Corporation are closed on such Conversion Date, in which event the
holder shall be deemed to have become the stockholder of record on the next
succeeding date on which the transfer books are open, provided that the
Conversion Price shall be that Conversion Price in effect on the Conversion
Date.

          A.7(b)(v)    Upon conversion of only a portion of the number of shares
covered by a Series C Preferred Certificate, the Corporation shall issue and
deliver to or upon the written order of the holder of such Series C Preferred
Certificate, at the expense of the Corporation, a new certificate covering the
number of shares of the Series C Stock representing the unconverted portion of
the Series C Preferred Certificate, which new certificate shall entitle the
holder thereof to all the rights, powers and privileges of a holder of such
shares.

          A.7(c)(i)    If a Series C Stockholder shall surrender more than one
share of Series C Stock for conversion at any one time, then the number of full
shares of Common Stock issuable upon conversion thereof shall be computed on the
basis of the aggregate number of shares of Series C Stock so surrendered.

          A.7(c)(ii)   No fractional shares of Common Stock shall be issued upon
conversion of Series C Stock. The Corporation shall pay a cash adjustment for
any such fractional interest in an amount equal to the Current Market Price
thereof on the Conversion Date, as determined in accordance with Section
A.7(d)(vii) hereof.

          A.7(d)       For all purposes of this Part A, the "Conversion Price"
with respect to the Series C Stock shall be equal to the Original Purchase Price
(as hereinafter defined) with respect to each such share of Series C Stock,
subject to adjustment from time to time as follows:

                       A.7(d)(i) If the Corporation shall, at any time or from
time to time after the Original Issuance Date, issue any shares of Common Stock
or other securities convertible into, or exchangeable or exercisable for, shares
of Common Stock (including, but not limited to,
<PAGE>

Series C Stock), in each case other than Excluded Stock (as hereinafter
defined), for a consideration per share less than the applicable Conversion
Price in effect immediately prior to the issuance of such Common Stock, or
other securities, the Conversion Price for Series C Stock in effect immediately
prior to each such issuance shall automatically (except as otherwise provided in
this Section A.7(d)(i) be lowered to an amount determined as follows:

          First:    multiply total number of shares of Common Stock outstanding
                    --------
     (including any shares of Common Stock deemed to have been issued pursuant
     to subdivision (A.7(a)(i) of this clause (iv)) immediately prior to such
     issuance (it being understood that the shares of Common Stock issuable upon
     conversion of Series C Stock shall be deemed to be outstanding for all
     purposes of the computation required in this clause A.7(d)(i)) by the
     Conversion Price to be adjusted (as in effect immediately prior to such
     issuance);

       Second:      add the consideration received by the Corporation upon such
                    ---
     issuance to the product determined in clause "First": and

       Third:       divide the sum determined in clause "Second" by the total
                    ------
     number of shares of Common Stock outstanding (including any shares of
     Common Stock deemed to have been issued pursuant to subdivision A.7(a)(i)
     immediately after the issuance of such Common Stock (it being understood
     that the shares of Common Stock issuable upon conversion of the Series C
     Stock shall be deemed to be outstanding for all purposes of the computation
     required in this Clause A.7(a)(i)).

     For the purposes of any adjustment of the Conversion Price pursuant to this
Section A.7(d)(i), the following provisions shall be applicable:

                    A.7(d)(i)(A) In the case of the issuance of Common Stock in
whole or in part for cash, the consideration shall be deemed to be the amount of
cash paid therefor after deducting therefrom any discounts, commissions or other
expenses allowed, paid or incurred by the Corporation for any underwriting or
otherwise in connection with the issuance and sale thereof, plus the value of
any property other than cash received by the Corporation, determined as provided
in Section A.7(d)(i)(13) hereof.

                    A.7(d)(i)(B) In the case of the issuance of Common Stock for
a consideration in whole or in part in property other than cash, the value of
such property or consideration other than cash shall be deemed to be the fair
market value of such property as determined in good faith by the Board of
Directors, irrespective of any accounting treatment: provided, however, that
                                                     --------  -------
such fair market value as determined by the Board of Directors shall not exceed
the aggregate Current Market Price (as defined in Section A. 7(d)(vii) hereof)
of the shares of Common Stock being issued, less any cash consideration paid for
such shares, determined as provided in Section A.7(d)(i)(A) hereof.

                    A.7(d)(i)(C) In the ease of the issuance of Common Stock for
consideration in whole or in part other than cash or property, the value of such
consideration shall be deemed to be the aggregate par value of such Common Stock
(or the aggregate stated
<PAGE>

value if such Common Stock, has no par value), less the value of any other
consideration received by the Corporation, determined as provided in Sections
A..7(d)(i)(A) and (B) hereof.

               A. 7(d)(i)(D)   In the case of the issuance of options or other
rights to purchase or subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock or options to purchase or
other rights to subscribe for such convertible or exchangeable securities
(collectively, the "Convertible Securities"):

               A.7(d)(i)(D)(l) the aggregate maximum number of shares of Common
Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in Section A.7(d)(i)(A), (B) and (C) hereof),
if any, received by the Corporation upon the issuance of such options or rights
plus the minimum purchase price provided in such options or rights for the
Common Stock covered thereby (the consideration in each case to be determined in
the manner provided in Sections A.7(d)(i)(A), (B) and (C) hereof);

               A.7(d)(i)(D)(2) the aggregate maximum number of shares of Common
Stock deliverable upon conversion of, or in exchange for, any such convertible
or exchangeable securities or upon the exercise of options to purchase or rights
to subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration received by the Corporation for any
such securities and related options or rights (excluding any cash received on

               A.7(d)(i)(D)(4) upon the expiration without being exercised of

exchange such convertible or exchangeable securities, the Conversion Price shall

been issued.

excluding any Series C Stock redeemed pursuant to Section A.4(f) hereof in
connection therewith) such that each share of Series C Stock outstanding
immediately prior to the effectiveness of the extraordinary Transaction (other
than the shares redeemed pursuant to Section A.4(f) hereof) shall be convertible
into the kind and number of shares of stock or other securities or property of
the Corporation, or of the corporation resulting from or surviving such
Extraordinary Transaction, that a holder of the number of shares of Common Stock
deliverable (immediately prior to the effectiveness of the Extraordinary
Transaction) upon conversion of such share of Series C Stock would have been
entitled to receive upon such Extraordinary Transaction. The provisions of this
Section A.7(d)(v) shall similarly apply to successive Extraordinary
Transactions.

               A.7(d)(vi)     All calculations under this Section A.7(d) shall
be made to the nearest one-tenth of a cent ($.00l) or to the nearest one-tenth
of a share, as the case may be.

               A.7(d)(vii)    For the purpose of any computation pursuant to
Section A.7(c) hereof or this Section A.7(d), the Current Market Price at any
date of one share of Common Stock shall be deemed to be the average of the daily
closing prices for the 30 consecutive business days ending on the fifth (5th)
business day before the day in question (as adjusted for any stock dividend,
split-up, combination or reclassification that took effect during such
30-business-day period) as follows:

               A.7(d)(vii)(A) If the Common Stock is listed or admitted for
trading on a national securities exchange, then the closing price for each day
shall be the last reported sales price regular way or, in case no such reported
sales took place on such day, the average of the last reported bid and asked
prices regular way, in either case on the principal national securities exchange
on which the Common Stock is listed or admitted to trading.

               A.7(d)(vii)(B) If the Common Stock is not at the time listed or
admitted for trading on any such exchange, then such price as shall be equal to
the last reported sales price, or if there is no such sale price, the average of
the last reported bid anti asked prices, as reported by the National Association
of Securities Dealers Automated Quotation System ("NASDAQ") on such day.

               A.7(d)(vii)(C) If the Common Stock is not at the time quoted on
the NASDAQ, then such price shall be equal to the last reported bid and asked
prices on such day as reported by the National Quotation Bureau, Inc., or any
similar reputable quotation and reporting service, if such quotation is not
reported by the National Quotation Bureau, Inc.
<PAGE>

               A.7(d)(vii)(D) If the Common Stock is not traded in such manner
that the quotations referred to in this Section A.7(d)(vii) are available for
the period required hereunder, then the Current Market Price shall be the fair
market value of such share, as determined in good faith by a majority of the
entire Board of Directors.

               A.7(d)(viii) In any case in which the provisions of this
Section A.7(d) shall require that an adjustment shall become effective
immediately after a record date for an event, the Corporation may defer until
the occurrence of such event (A) issuing to the holder of any shares of Series C
Stock converted after such record date and before the occurrence of such event
the additional shares of capital stock issuable upon such conversion by reason
of the adjustment required by such event over and above the shares of capital
stock issuable upon such conversion before giving effect to such adjustment, and
(B) paying to such holder any cash amounts in lieu of fractional shares pursuant
to Section A.7(c)(ii) hereof; provided, however, that the Corporation shall
                              --------  -------
deliver to such holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional shares, and such cash, upon the
occurrence of the event requiring such adjustment.

               A.7(d)(ix) If a state of facts shall occur that, without being
specifically controlled by the provisions of this Section A.7, would not fairly
protect the conversion rights of the holders of the Series C Stock in accordance
with the essential intern and principles of such provisions, then the Board of
Directors shall make an adjustment in the application of such provisions, in
accordance with such essential intent and principles, so as to protect such
conversion rights.

               A.7(e) Whenever the Conversion Price shall be adjusted as
provided in Section A.7(d) hereof, the Corporation shall forthwith file and keep
on record at the office of the Secretary of the Corporation and at the office of
the transfer agent for the Series C Stock or at such other place as may be
designated by the Corporation, a statement, signed by its President or Chief
Executive Officer and by its Treasurer or Chief Financial Officer, showing in
detail the facts requiring such adjustment and the Conversion Price that shall
be in effect after such adjustment. The corporation shall also cause a copy of
such statement to be sent by first-class, certified mail, return receipt
requested, postage prepaid, to each Series C Stockholder at such holder's
address appearing on the Corporation's records. Where appropriate, such copy
shall be given in advance of any such adjustment and shall be included as part
of a notice required to be mailed under the provisions of Section A.7(t) hereof.

               A.7(f) In the event the Corporation shall propose to take any
action of the types described in Section A.7(d)(i), (iii), (iv) or (v) hereof,
or any other Event of Sale, the Corporation shall give notice to each Series C
Stockholder in the manner set forth in Section A.7(e) hereof, which notice shall
specify the record date, if any, with respect to any such action and the date on
which such action is to take place. Such notice shall also set forth such facts
with respect thereto as shall be reasonably necessary to indicate the effect of
such action (to the extent such effect may be known at the date of such notice)
on the Conversion Price with respect to the Series C Stock, and the number, kind
or class of shares or other securities or property which shall be deliverable or
purchasable upon each conversion of Series C Stock. In the case of any action
that would require the fixing of a record date, such notice shall be given at
least 20 days prior to
<PAGE>

the record date so fixed, and in the case of any other action, such notice shall
be given at least 30 days prior to the taking of such proposed action.

               A.7(g) The Corporation shall pay all documentary, stamp or other
transactional taxes attributable to the issuance or delivery of shares of
capital stock of the Corporation upon conversion of any shares of Series C
Stock: provided, however that the Corporation shall not be required to pay any
       --------  -------
taxes which may be payable in respect of any transfer involved in the issuance
or delivery of any certificate for such shares in a name other than that of the
Series C Stockholder in respect of which such shares of Series C Stock are being
issued.

               A.7(h) The Corporation shall reserve out of its authorized but
unissued shares of Common Stock solely for the purpose of effecting the
conversion of the Series C Stock sufficient shares of Common Stock to provide
for the conversion of all outstanding shares of Series C Stock.

               A.7(i) All shares of Common Stock which may be issued in
connection with the conversion provisions set forth herein will, upon issuance
by the Corporation, be validly issued, fully paid and nonassessable, not subject
to any preemptive or similar rights and free from all taxes, liens or charges
with respect thereto created or imposed by the Corporation.

               A.7(j) in the event that, at any time while any of the Series C
Preferred Stock shall be outstanding, the Corporation shall consummate an
underwritten public offering on a firm commitment basis pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock providing aggregate net proceeds to the
Corporation equal to at least $25,000,000 having a per share offering price of
at least $15.00 as presently constituted (a "Qualifying Public Offering"), then
all outstanding shares of Series C Preferred Stock shall, automatically and
without further action on the part of the holders of the Series C Preferred
Stock, be converted into shares of Common Stock with the same effect as if the
certificates evidencing such shares had been surrendered for conversion, such
conversion to be effective simultaneously with the closing of such public
offering; provided, however, that certificates evidencing the shares of Common
Stock issuable upon such conversion shall not be issued except on surrender of
the certificates for the shares of the Series C Preferred Stock so converted.
Each share of Series C Preferred Stock shall be converted into fully paid and
nonassessable shares (calculated to the nearest 1/100 of a share) of Common
Stock at the Conversion Price in effect on the Conversion Date.

          Section A.8  Definitions. As used in Section A of this Certificate of
                       -----------

     price of the Series C Stock upon the occurrence of a stock split, reverse
     stock split, stock dividend, stuck combination, reclassification or other
     similar change with respect to such security, such that the price of one
     share of the Series C Stock before the occurrence of any such change shall
     equal the aggregate price of the share (or shares or fractional share) of
     such security (or any other security) received by the holder of the
     Series C Stock with respect thereto upon the effectiveness of such change.

- --------  -------
D Preferred to a number less than the number of shares then outstanding plus the
number of shares reserved for issuance upon the exercise of outstanding options,
rights or warrants or upon the conversion of any outstanding securities issued
by the Corporation and convertible into Series D Preferred.


     2.   Liquidation Rights.
          ------------------

     (a)  Treatment at Liquidation, Dissolution or Winding Up.
          ---------------------------------------------------

          (i)  Except as otherwise provided in Section 2(b) below, in the event
     of any liquidation, dissolution or winding up of the affairs of the
     Corporation, whether voluntary or involuntary, the holders of Series D
     Preferred shall be entitled to be paid out of the assets of the Corporation
     available for distribution to holders of the Corporation's capital stock of
     all classes, after and subject to the payment in full of all amounts
     required to be distributed to the holders of Series A Preferred Stock,
     $.001 par value per share (the "Series A Preferred"), the holders of the
     Series B Preferred Stock, $.001 par value per share (the "Series B
     Preferred"), the holders of Series C Preferred Stock, $.001 par value per
     share (the "Series C Preferred") pursuant to Section A.4(b) of the
     Certificate of Designation for such Series C Preferred, and the holders of
     any other class or series of stock of the Corporation on liquidation prior
     and in preference to the Series D Preferred, but before payment or
     distribution of any of such assets to the holders of any other class or
     series of the Corporation's capital stock designated to be junior to the
     Series D Preferred, on a pro rata basis together with the holders of the
     Series C Preferred, an amount equal to $12.25 per share of Series D
     Preferred (which amount shall be subject to equitable adjustment whenever
     there shall occur a stock dividend, distribution, combination of shares,
     reclassification or other similar event with respect to Series D Preferred
     and, as so adjusted from time to time, is hereinafter referred to as the
     "Base Liquidation Price") and Series C Preferred then outstanding, plus all
     dividends accrued or declared but unpaid, to and including the date full
     payment shall be tendered to the holders of Series D Preferred with respect
     to such liquidation, dissolution or winding up.

          (ii) Following payment in full to the holders of Series A Preferred,
     Series B Preferred, Series C Preferred and Series D Preferred of all
     amounts distributable to them under Section 2(a)(i) hereof, the remaining
     assets of the Corporation available for distribution to holders of the
     Corporation's capital stock shall be distributed on a pro rata basis among
     the holders of the Common Stock and the Series C Preferred.
<PAGE>

          (iii)  If the assets of the Corporation shall be insufficient to
     permit the payment in full to the holders of Series D Preferred and the
     Series C Preferred of all amounts distributable to them under Section
     2(a)(i) hereof, then the entire assets of the Corporation available for
     such distribution shall be distributed ratably among the holders of  the
     Series D Preferred and the Series C Preferred.

     (b)  Treatment of Reorganizations, Consolidations, Mergers and Sales of
          ------------------------------------------------------------------
Assets.  Except as otherwise provided in Subsection 3(d)(vii) hereof, a
- ------
Reorganization (as defined in Subsection 3(d)(vii) hereof) shall be regarded as
a liquidation, dissolution or winding up of the affairs of the Corporation
within the meaning of this Section 2, provided, however, that the holders of at
                                      --------  -------
least a majority of the outstanding shares of the Series D Preferred upon the
occurrence of a Reorganization shall have the option to elect the benefits of
Subsection 3(d)(vii) hereof for the Series D Preferred in lieu of receiving
payment in liquidation, dissolution or winding up of the Corporation pursuant to
this Section 2. The provisions of this Subsection 2(b) shall not apply to any
reorganization, merger or consolidation involving (1) only a change in the state
of incorporation of the Corporation, (2) a merger of the Corporation with or
into a wholly-owned subsidiary of the Corporation which is incorporated in the
United States of America, or (3) an acquisition by merger, reorganization or
consolidation, in which the Corporation is substantively the surviving
corporation and operates as a going concern, of another corporation which is
incorporated in the United States of America and which is engaged in a business
similar to or related to the business of the Corporation and which does not
involve a change in the terms of the Series D Preferred or of the Common Stock.

     (c)  Distributions other than Cash.  Whenever the distribution provided for
          -----------------------------
in this Section 2 shall be payable in property other than cash, the value of
such distribution shall be the fair market value of such property as determined
in good faith by the Board of Directors of the Corporation.

     3.   Conversion.  The holders of Series D Preferred shall have conversion
          ----------
rights as follows (the "Conversion Rights"):

     (a)  Right to Convert; Conversion Price.  Each share of Series D Preferred
          ----------------------------------
shall be convertible, without the payment of any additional consideration by the
holder thereof and at the option of the holder thereof, at any time after the
date of issuance of such share, at the office of the Corporation or any transfer
agent for the Series D Preferred, into such number of fully paid and non-
assessable shares of Common Stock as is determined by dividing $12.25 by the
Conversion Price, determined as hereinafter provided, in effect at the time of
conversion. The Conversion Price for purposes of calculating the number of
shares of Common Stock deliverable upon conversion without the payment of any
additional consideration by the holder of Series D Preferred (the "Conversion
Price") shall initially be $12.25. Such initial Conversion Price shall be
subject to adjustment, in order to adjust the number of shares of Common Stock
into which Series D Preferred is convertible, as hereinafter provided.

     (b)  Mechanics of Conversion.  Before any holder of Series D Preferred
          -----------------------
shall be entitled to convert the same into full shares of Common Stock, such
holder shall surrender the certificate or certificates therefor, duly endorsed,
at the office of the Corporation or of any transfer agent for the
<PAGE>

Series D Preferred, and shall give written notice to the Corporation at such
office that such holder elects to convert the same and shall state therein the
name of such holder or the name or names of the nominees of such holder in which
such holder wishes the certificate or certificates for shares of Common Stock to
be issued. No fractional shares of Common Stock shall be issued upon conversion
of any shares of Series D Preferred. In lieu of any fractional shares of Common
Stock to which the holder would otherwise be entitled, the Corporation shall pay
cash equal to such fraction multiplied by the then effective Conversion Price.
The Corporation shall, as soon as practicable thereafter, issue and deliver at
such office to such holder of Series D Preferred, or to such holder's nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which such holder shall be entitled as aforesaid, together with cash in lieu
of any fraction of a share. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of Series D Preferred to be converted, and the person or persons entitled
to receive the shares of Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
on such date.

     (c)  Automatic Conversion.
          --------------------

          (i) Each share of Series D Preferred shall automatically be converted
     into shares of Common Stock at the then effective Conversion Price upon the
     closing of a firm commitment underwritten public offering pursuant to an
     effective registration statement under the Securities Act of 1933, as
     amended, covering the offer and sale of Common Stock for the account of the
     Corporation to the public with net proceeds to the Corporation of not less
     than $15,000,000 (a "Qualified Initial Public Offering").

          (ii) Upon the occurrence of an event specified in Section 3(c)(i)
     hereof, all shares of Series D Preferred shall be converted automatically
     without any further action by any holder of such shares and whether or not
     the certificate or certificates representing such shares are surrendered to
     the Corporation or the transfer agent for the Series D Preferred, provided,
     however, that the Corporation shall not be obligated to issue a certificate
     or certificates evidencing the shares of Common Stock into which such
     shares of Series D Preferred were convertible unless the certificate or
     certificates representing such shares of Series D Preferred being converted
     are either delivered to the Corporation or the transfer agent of the Series
     D Preferred, or the holder notifies the Corporation or such transfer agent
     that such certificate or certificates have been lost, stolen, or destroyed
     and executes and delivers an agreement satisfactory to the Corporation to
     indemnify the Corporation from any loss incurred by it in connection
     therewith and, if the Corporation so elects, provides an appropriate
     indemnity.

          (iii)  Upon the automatic conversion of Series D Preferred, each
     holder of Series D Preferred shall surrender the certificate or
     certificates representing such holder's shares of Series D Preferred at the
     office of the Corporation or of the transfer agent for the Series D
     Preferred.  Thereupon, there shall be issued and delivered to such holder,
     promptly at such office and in such holder's name as shown on such
     surrendered certificate or certificates, a certificate or certificates for
     the number of shares of Common Stock into which the shares of Series D
     Preferred surrendered were convertible on the date on which such automatic
     conversion occurred.  No fractional shares of Common Stock shall be issued
     upon the
<PAGE>

     automatic conversion of Series D Preferred. In lieu of any fractional
     shares of Common Stock to which the holder would otherwise be entitled, the
     corporation shall pay cash equal to such fraction multiplied by the then
     effective Conversion Price.

     (d)       Adjustments to Conversion Price for Diluting Issues.
          ---------------------------------------------------

          (i)  Special Definitions.  For purposes of this Section 3(d), the

                 on Form S-1;

                      (V)    335,000 shares of Common Stock issuable upon the

                 ---------------------------------
     of shares of Common Stock into which a share of Series D Preferred is

     of the issuance of Additional Shares of Common Stock or otherwise unless
     (i) the consideration per share for an Additional Share of Common Stock
     issued or deemed to be issued by the Corporation is less than the current
     market price per share of the Common Stock, as determined by the Board of
     Directors (the "Current Market Price"), on the date of the issue of such
     Additional Shares of Common Stock and, (ii) prior to such issuance, the
     Corporation fails to receive written notice from the holders of at least a

                 -----

                      (A)    Options and Convertible Securities.  In the event
                             ----------------------------------
          the Corporation at any time after the Original Issue Date shall issue
          any Options or Convertible Securities (other than the Excluded Shares)
          or shall fix a record date for the determination of holders of any
          class of securities entitled to receive any such Options or

          forth in the instrument relating thereto without regard to any
          provisions contained therein for a subsequent adjustment of such
          number) of Common Stock issuable upon the exercise of such Options or,
          in the case of Convertible Securities and Options therefor, the
          conversion or exchange of such Convertible Securities, shall be deemed
          to be Additional Shares of Common Stock issued as of the time of such
          issue or, in case such a record date shall have been fixed, as of the
          close of business on such record date, provided that Additional Shares
          of Common Stock shall not be deemed to have been issued unless the
          consideration per share (determined pursuant to Section 3(d)(v)
          hereof) of such Additional Shares of Common Stock would be less than
          the Current Market Price per share of Common Stock on the date of such
          issue, or such record date, as the case may be, and provided further
          that in any such case in which Additional Shares of Common Stock are
          deemed to be issued:
<PAGE>

                    (I)    No further adjustment in the Conversion Price shall
               be made upon the subsequent issue of Convertible Securities or
               shares of Common Stock upon the exercise of such Options or
               conversion or exchange of such Convertible Securities;

                    (II)   If such Options or Convertible Securities by their
               terms provide, with the passage of time or otherwise, for any
               increase in the consideration payable to the Corporation, or
               decrease in the number of shares of Common Stock issuable upon
               the exercise, conversion or exchange thereof, the Conversion
               Price computed upon the original issue thereof (or upon the
               occurrence of a record date with respect thereto), and any
               subsequent adjustments based thereon, shall, upon any such
               increase or decrease becoming effective, be recomputed to reflect
               such increase or decrease insofar as it affects such Options or
               the rights of conversion or exchange under such Convertible
               Securities;

                    (III)  Upon the expiration of any such options or any rights
               of conversion or exchange under such Convertible Securities which
               shall not have been exercised, the Conversion Price computed upon
               the original issue thereof (or upon the occurrence of a record
               date with respect thereto), and any subsequent adjustments based
               thereon, shall, upon such expiration, be recomputed as if:

                           (a)  In the case of Convertible Securities or Options
                    for Common Stock the only Additional Shares of Common Stock
                    issued were the shares of Common Stock, if any, actually
                    issued upon the exercise of such Options or the conversion
                    or exchange of such Convertible Securities and the
                    consideration received therefor was the consideration
                    actually received by the Corporation for the issue of all
                    such Options, whether or not exercised, plus the
                    consideration actually received by the Corporation upon such
                    exercise, or for the issue of all such Convertible
                    Securities which were actually converted or exchanged, plus
                    the additional consideration, if any, actually received by
                    the Corporation upon such conversion or exchange; and

                           (b)  In the case of Options for Convertible
                    Securities only the Convertible Securities, if any, actually
                    issued upon the exercise thereof were issued at the time of
                    issue of such Options, and the consideration received by the
                    Corporation for the Additional Shares of Common Stock deemed
                    to have been then issued was the consideration actually
                    received by the Corporation for the issue of all such
                    Options, whether or not exercised, plus the consideration
                    deemed to have been received by the Corporation (determined
                    pursuant to Section 3(d)(v)) upon the issue of the
                    Convertible
<PAGE>

                    Securities with respect to which such Options were actually
                    exercised;

                    (IV)   No readjustment pursuant to clause (II) or (III)
               above shall have the effect of increasing the Conversion Price to
               an amount which exceeds the lower of (a) the Conversion Price on
               the original adjustment date, or (b) the Conversion Price that
               would have resulted from any issuance of Additional Shares of
               Common Stock between the original adjustment date and such
               readjustment date;

                    (V)    In the case of any Options which expire by their
               terms not more than 30 days after the date of issue thereof, no
               adjustment of the Conversion Price shall be made until the
               expiration or exercise of all such Options, whereupon such
               adjustment shall be made in the same manner provided in clause
               (III) above; and

                    (VI)   If such record date shall have been fixed and such
               Options or Convertible Securities are not issued on the date
               fixed therefor, the adjustment previously made in the Conversion
               Price which became effective on such record date shall be
               canceled as of the close of business on such record date, and
               thereafter the Conversion Price shall be adjusted pursuant to
               this Section 3(d)(iii) as of the actual date of their issuance.

               (B)  Stock Dividends, Stock Distributions and Subdivisions.  In
                    -----------------------------------------------------
          the event the Corporation at any time or from time to time after the
          Original Issue Date shall declare or pay any dividend or make any
          other distribution on the Common Stock payable in Common Stock or
          effect a subdivision of the outstanding shares of Common Stock (by
          reclassification or otherwise than by payment of a dividend in Common
          Stock), then and in any such event, Additional Shares of Common Stock
          shall be deemed to have been issued:

                    (I)    In the case of any such dividend or distribution,
               immediately after the close of business on the record date for
               the determination of holders of any class of securities entitled
               to receive such dividend or distribution, or

                    (II)   In the case of any such subdivision, at the close of
               business on the date immediately prior to the date upon which
               corporate action becomes effective.

               If such record date shall have been fixed and no part of such
          dividend shall have been paid on the date fixed therefor, the
          adjustment previously made for the Conversion Price which became
          effective on such record date shall be canceled as of the close of
          business on such record date, and thereafter the Conversion Price
          shall be adjusted pursuant to this Section 3(d)(iii) as to the time of
          actual payment of such dividend.

          (iv) Adjustment of Conversion Price Upon Issuance of Additional Shares
               -----------------------------------------------------------------
     of Common Stock.
     ---------------

                    (A)  In the event the Corporation shall issue Additional
          Shares of Common Stock (including, without limitation, Additional
          Shares of Common Stock deemed to be issued pursuant to Section
          3(d)(iii) but excluding Additional Shares of Common Stock deemed to be
          issued pursuant to Section 3(d)(iii)(B), which event is dealt with in
          Section 3(d)(vi) hereof), without consideration or for a consideration
          per share less than the Current Market Price per share of Common Stock
          on the date of such issue, then and in such event, such Conversion
          Price shall be reduced, concurrently with such issue, to a price
          (calculated to the nearest cent) determined by multiplying such
          Conversion Price by a fraction, the numerator of which shall be (I)
          the number of shares of Common Stock outstanding immediately prior to
          such issue plus (II) the number of shares of Common Stock which the
          aggregate consideration received or deemed to have been received by
          the Corporation for the total number of Additional Shares of Common
          Stock so issued would purchase at such Conversion Price, and the
          denominator of which shall be (I) the number of shares of Common Stock
          outstanding immediately prior to such issue plus (II) the number of
          Additional Shares of Common Stock so issued or deemed to be issued.

                    (B)  For the purposes of Section 3(d)(iv)(A) hereof, (i) all
          shares of Common Stock issuable upon conversion of shares of Series D
          Preferred, and upon exercise of options or conversion or exchange of
          Convertible Securities which are part of the Excluded Shares,
          outstanding immediately prior to any issue of Additional Shares of
          Common Stock, or any event with respect to which Additional Shares of
          Common Stock shall be deemed to be issued, shall be deemed to be
          outstanding and (ii) immediately after any Additional Shares of Common
          Stock are deemed issued pursuant to Section 3(d)(iii), such Additional
          Shares of Common Stock shall be deemed to be outstanding.

                    (C)  Notwithstanding anything to the contrary contained
          herein, the applicable Conversion Price in effect at the time
          Additional Shares of Common Stock are issued or deemed to be issued
          shall not be reduced pursuant to Section 3(d)(iv)(A) hereof at such
          time if the amount of such reduction would be an amount less than
          $0.05, but any such amount shall be carried forward and reduction with
          respect thereto made at the time of and together with any subsequent
          reduction which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate $0.05 or more.

          (v)  Determination of Consideration.  For purposes of this Section
               ------------------------------
     3(d), the consideration received by the Corporation for the issue of any
     Additional Shares of Common Stock shall be computed as follows:
<PAGE>

               (A)  Cash and Property.  Such consideration shall:
                    -----------------

                         (I)    Insofar as it consists of cash, be computed at
               the aggregate amounts of cash received by the Corporation
               excluding amounts paid or payable for accrued interest or accrued
               dividends;

                         (II)   Insofar as it consists of property other than
               cash, be computed at the fair market value thereof at the time of
               such issue, as determined in good faith by the Board of
               Directors; and

                         (III)  In the event that Additional Shares of Common
               Stock are issued together with other shares or securities or
               other assets of the Corporation for consideration which covers
               both, be the proportion of such consideration so received,
               computed as provided in clauses (I) and (II) above, as determined
               in good faith by the Board of Directors.

                    (B)  Options and Convertible Securities.  The consideration
                         ----------------------------------
     per share received by the Corporation for Additional Shares of Common Stock
     deemed to have been issued pursuant to Section 3(d)(iii)(A), relating to
     Options and Convertible Securities, shall be determined by dividing (I) the
     total amount, if any, received or receivable by the Corporation as
     consideration for the issue of such Options or Convertible Securities, plus
     the minimum aggregate amount of additional consideration (as set forth in
     the instruments relating thereto, without regard to any provision contained
     therein for a subsequent adjustment of such consideration) payable to the
     Corporation upon the exercise of such Options or the conversion or exchange
     of such Convertible Securities, or in the case of Options for Convertible
     Securities, the exercise of such Options for Convertible Securities and the
     conversion or exchange of such Convertible Securities, by (II) the maximum
     number of shares of Common Stock (as set forth in the instruments relating
     thereto, without regard to any provision contained therein for a subsequent
     adjustment of such number) issuable upon the exercise of such Options or
     the conversion or exchange of such Convertible Securities.

     (vi) Adjustment for Dividends, Distributions, Subdivisions, Combinations or
          ----------------------------------------------------------------------
Consolidations of Common Stock.
- ------------------------------

                    (A)  Stock Dividends, Distributions or Subdivisions.  In the
                         ----------------------------------------------
     event the Corporation shall issue Additional Shares of Common Stock
     pursuant to Section 3(d)(iii)(B) in a stock dividend, stock distribution or
     subdivision, the Conversion Price in effect immediately prior to such stock
     dividend, stock distribution or subdivision shall, concurrently with the
     effectiveness of such stock dividend, stock distribution or subdivision, be
     proportionately decreased.
<PAGE>

                    (B)  Combinations or Consolidations.  In the event the
                         ------------------------------
          outstanding shares of Common Stock shall be combined or consolidated,
          by reclassification or otherwise, into a lesser number of shares of
          Common Stock, the Conversion Price in effect immediately prior to such
          combination or consolidation shall, concurrently with the
          effectiveness of such combination or consolidation, be proportionately
          increased.

          (vii)  Capital Reorganization, Merger or Sale of Assets.  If at any
                 ------------------------------------------------
     time or from time to time there shall be a capital reorganization of the
     Common Stock (other than a subdivision, combination, recapitalization,
     reclassification or exchange of shares provided for elsewhere in this
     Section 3) or a consolidation or merger of the Corporation, or a sale of
     all or substantially all of the assets of the Corporation, other than a
     merger, consolidation or sale of all or substantially all of the assets of
     the Corporation in a transaction in which the shareholders of the
     Corporation immediately prior to the transaction possess more than 50% of
     the voting securities of the surviving entity (or parent, if any)
     immediately after the transaction (a "Reorganization"), then, as a part of
     and as a condition to such Reorganization, provision shall be made so that
     the holders of shares of the Series D Preferred shall thereafter be
     entitled to receive upon conversion of the shares of the Series D Preferred
     the same kind and amount of stock or other securities or property
     (including cash) of the Corporation, or of the successor corporation
     resulting from such Reorganization, to which such holder would have been
     entitled if such holder had converted its shares of the Series D Preferred
     immediately prior to the effective time of such Reorganization. In any such
     case, appropriate adjustment shall be made in the application of the
     provisions of this Section 3 to the end that the provisions of this Section
     3 (including adjustment of the Conversion Price then in effect and the
     number of shares of Common Stock or other securities issuable upon
     conversion of the shares of the Series D Preferred) shall be applicable
     after such Reorganization in as nearly equivalent manner as may be
     reasonably practicable.

          In the case of a transaction to which both this Subsection 3(d)(vii)
     and Subsection 2(b) hereof apply, the holders of at least a majority of the
     outstanding shares of the Series D Preferred upon the occurrence of a
     Reorganization shall have the option to elect treatment either under this
     Subsection 3(d)(vii) or under Subsection 2(b) hereof, notice of which
     election shall be given in writing to the Corporation not less than five
     (5) business days prior to the effective date of such Reorganization. If no
     such election is timely made, the provisions of Subsection 2(b) and not of
     this Subsection 3(d)(vii) shall apply.

          The provisions of this Subsection 3(d)(vii) shall not apply to any
     reorganization, merger or consolidation involving (1) only a change in the
     state of incorporation of the Corporation, (2) a merger of the Corporation
     with or into a wholly-owned subsidiary of the Corporation which is
     incorporated in the United States of America, or (3) an acquisition by
     merger, reorganization or consolidation, in which the Corporation is
     substantively the surviving corporation and operates as a going concern, of
     another corporation which is incorporated in the United States of America
     and which is engaged in a business similar to or related to the business of
     the Corporation and which does not involve a change in the terms of the
     Series D Preferred or of the Common Stock.
<PAGE>

     (e)  No Impairment.  The Corporation shall not, by amendment of its
          -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation but shall at
all times in good faith assist in the carrying out of all the provisions of this
Section 3 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of Series D
Preferred against impairment.

     (f)  Certificate as to Adjustments.  Upon the occurrence of each adjustment
          -----------------------------
or readjustment of the Conversion Price or Conversion Ratio pursuant to this
Section 3, the Corporation at its expense shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and furnish to each affected
holder of Series D Preferred, a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any affected holder of Series D Preferred furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price or Conversion Ratio at the time in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which at the
time would be received upon conversion of each share of Series D Preferred.

     (g)  Notices of Record Date.  In the event of any taking by the
          ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend which is the same as cash dividends paid in
previous quarters) or other distribution, the Corporation shall mail to each
holder of Series D Preferred at least ten (10) days prior to such record date a
notice specifying the date on which any such record is to be taken for the
purpose of such dividend or distribution.

     (h)  Common Stock Reserved.  The Corporation shall reserve and keep
          ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of Series D Preferred.

     (i)  Certain Taxes.  The Corporation shall pay any issue or transfer taxes
          -------------
payable in connection with the conversion of any shares of Series D Preferred,
provided, however, that the Corporation shall not be required to pay any tax
- --------  -------
which may be payable in respect of any transfer to a name other than that of the
holder of such Series D Preferred.

     (j)  Closing of Books.  The corporation shall not close its transfer books
          ----------------
against the transfer of any Series D Preferred, or of any shares of Common Stock
issued or issuable upon the conversion of any shares of Series D Preferred in
any manner which interferes with the timely conversion or transfer of such
Series D Preferred, unless, at the request of the Company or an underwriter, the
holders of the Series D Preferred shall have agreed not to sell or otherwise
transfer or dispose of any Common Stock (or other securities) of the Company
held by such holders during a period not to exceed one hundred and eighty (180)
days following the effective date of a registration statement of the Company
filed under the Securities Act, in which case the Company may impose stop-
transfer instructions with respect to the shares (or securities) subject to the
foregoing restriction until the end of said period.
<PAGE>

     4.   Voting Rights.
          -------------

     (a)  Except as otherwise required by law or this Certificate of
Incorporation, or as provided in Section 6 hereof, the holders of Series A
Preferred, Series B Preferred, Series C Preferred, Series D Preferred and Common
Stock shall be entitled to notice of any stockholders' meeting and to vote
together as a single class upon any matter submitted to the stockholders for a
vote, on the following basis:

          (i)    Holders of Common Stock shall have one vote per share of Common
     Stock held by them; and

          (ii)   Holders of Series D Preferred shall have that number of votes
     per share of Series D Preferred as is equal to the number of shares of
     Common Stock into which each such share of Series D Preferred held by such
     holder could be converted on the date for determination of stockholders
     entitled to vote at the meeting.

     (b)  Notwithstanding the foregoing, the holders of Series D Preferred shall
vote as a separate class on any matters as to which a separate class vote is
required by law, Section 6 of this Certificate of Designation or the Certificate
of Incorporation.

     5.   Dividend Rights.
          ---------------

     (a)  The holders of shares of Series D Preferred shall be entitled to
receive, when, as and if declared or paid by the Board of Directors on any
shares of Series D Preferred, out of funds legally available for that purpose,
dividends and distributions (whether in cash, property or securities of the
Corporation, including subscription or other rights to acquire securities of the
Corporation). Whenever any dividend may be declared or paid on any shares of
Series D Preferred, the Board of Directors shall also declare and pay a dividend
on the same terms, at the same rate and in like kind upon each other share of
the Series D Preferred then outstanding, so that all outstanding shares of
Series D Preferred will participate equally with each other ratably per share
(calculated as provided in Section 5(b) hereof).

     (b)  In connection with any dividend declared or paid hereunder, each share
of Series D Preferred shall be deemed to be that number of shares of Common
Stock into which it is then convertible, rounded up to the nearest one-tenth of
a share. No fractional shares of capital stock shall be issued as a dividend
hereunder. The Corporation shall pay a cash adjustment for any such fractional
interest in an amount equal to the fair market value thereof on the last
business day immediately preceding the date for payment of dividends, as
determined by the Board of Directors in good faith.

     (c)  Notwithstanding the foregoing provisions of this Section 5: (i) upon
any conversion of the Series D Preferred pursuant to Section 3 above, all
accrued and unpaid dividends on such shares of Series D Preferred to and until
the date of such conversion shall be forfeited and shall not be due and payable;
and (ii) the payment of all or any portion of accrued and unpaid dividends on
<PAGE>

Series D Preferred may be waived by the affirmative vote of holders of not less
than a majority in interest of the Series D Preferred, voting as a separate
class.

          6.   Covenants.  So long as ten percent (10%) of the originally issued
               ---------
shares of Series D Preferred remain outstanding, unless there is given the
written consent of at least a majority of the Series D Preferred outstanding not
beneficially owned by any record holder of Series A Preferred, Series B
Preferred or Series C Preferred voting as a class, the Corporation shall not
undertake any amendment of this Certificate of Designation or the Certificate of
Incorporation if such amendment would alter or change the preferences, voting
power, qualifications or special or relative rights or privileges of the Series
D Preferred so as to affect the holders thereof in a materially adverse manner;
provided that the designation and issuance of any additional class or classes of
- --------
Preferred Stock expressly shall not be deemed to be materially adverse to the
holders of the Series D Preferred. The holders of at least a majority of the
aggregate number of shares of Series D Preferred outstanding may, by affirmative
vote or consent as aforesaid, agree to a change or alteration by the Corporation
in the preferences, voting powers, qualifications and special or relative rights
and privileges of the Series D Preferred, or may waive the application thereof
in any particular instance.

     7.   Ranking.  The Series D Preferred shall rank, as to dividends and upon
          -------
Liquidation (as defined in Section 2 hereof), equally with each other but junior
to the Series A Preferred, Series B Preferred and Series C Preferred, and senior
and prior to the Corporation's Common Stock, except as otherwise approved by the
affirmative vote or consent of the holders of the Series D Preferred pursuant to
Section 6 hereof.

     8.   No Reissuance of Series D Preferred.   No share or shares of Series D
          -----------------------------------
Preferred acquired by the Corporation by reason of redemption, purchase,
conversion or otherwise shall be reissued, and all such shares shall be
canceled, retired and eliminated from the shares which the corporation shall be
authorized to issue.

     9.   Residual Rights.  All rights accruing to the outstanding shares of the
          ---------------
Corporation not expressly provided for in the terms of the Series A preferred,
Series B Preferred, Series C Preferred and Series D Preferred shall be vested in
the Common Stock.

EIGHTH:   That Article FOURTH of the Certificate of Incorporation be further
- ------
          revised by amending the Series C Certificate of Designation by

          the following:

          "Section A.4  Liquidation Rights.
                        ------------------

     A.4(a) With respect to rights on Liquidation (as defined in
     Section A.4(b) hereof), the Series C Stock shall rank
     equally with each other and with each other holder of shares
     of Series A Stock, Series B Stock and Series E Stock, and
     senior and prior to the Corporation's Common Stock and to
     all other classes or series of stock issued by the
     Corporation, except as otherwise approved by the affirmative
     vote or consent of the holders of Series C Stock pursuant to
     Section A.6(c) hereof.

     A.4(b) Subject to Section A.4(a) above, in the event of any
     liquidation, dissolution or winding-up of the affairs of the
     Corporation (collectively, a "Liquidation"), the holders of
     shares of Series C Stock then outstanding (the "Series C
     Stockholders") shall be entitled to receive out of the
     assets of the Corporation legally available for distribution
     to its stockholders, whether from capital, surplus or
     earnings, pari passu with the holders of
<PAGE>

     Parity Securities, but before any payment shall be made to
     the holders of Common Stock or any other class or series of
     stock ranking on Liquidation junior to such Series C Stock,
     an amount per share equal to the Original Purchase Price (as
     defined in Section A.8 hereof), plus, in each case, an
     amount equal to any accrued and declared but unpaid
     dividends thereon pursuant to Section A.3(a) hereof.

               A.4(c) Subject to Section A.4(a) above, if, upon any
     Liquidation, the assets of the Corporation available for
     distribution to its stockholders shall be insufficient to pay the
     Series C Stockholders and all other holders of Parity Securities
     the full amount as to which each of them shall be entitled
     pursuant to Section A.4(b), then the Series C Stockholders and
     all other holders of Parity Securities shall first share ratably
     in any distribution of assets according to the respective amounts
     which would be payable to them in respect of the shares held upon
     such distribution if all amounts payable on or with respect to
     such shares were paid in full. For purposes of calculating the
     amount of any payment to be paid upon any such Liquidation, each
     share of Series C Stock shall be deemed to be that number of
     shares (including fractional shares) of Common Stock into which
     it is then convertible, rounded to the nearest one-tenth of a
     share.

               A.4(d) In the event of any Liquidation, after payment
     shall have been made to the Series C Stockholders and all other
     holders of Parity Securities of the full amount to which they
     shall be entitled pursuant to Section A.4(b), with respect to
     each other class or series of capital stock (other than Common
     Stock) ranking on Liquidation junior to such Series C Stock (in
     descending order of seniority ), the Series C Stockholders and
     Series E Stockholders, as a class, shall be entitled to receive
     an amount equal and in like kind) to the aggregate preferential
     amount fixed for each such junior class or series of capital
     stock, which amount shall be distributed among the Series C
     Stockholders and Series E Stockholders in an equal amount per
     share of the Series C Stock and Series E Stock, respectively then
     outstanding. If, upon any Liquidation, the assets of the
     Corporation available for distribution to its stockholders shall
     be insufficient to pay the Series C Stockholders and Series E
     Stockholders and a class or series of capital stock (other than
     the Common Stock) junior to the Series C Stock and Series E Stock
     the full amounts to which they shall be entitled pursuant to the
     next preceding sentence, the holders of the Series C Stock,
     Series E Stock and such other class or series of capital stock
     shall share ratably in any distribution of assets according to
     the respective preferential amounts fixed for the Series C Stock
     and Series E Stock (pursuant to Section A.4(b)) and such junior
     class or series of
<PAGE>

     capital stock which would be payable in respect of the shares
     held by them upon such distribution if all amounts payable on or
     with respect to such shares were paid in full.

               A.4(e) In the event of any Liquidation, after payment
     shall have been made to the Series C Stockholders and Series E
     Stockholders of the full amount to which they shall be entitled
     as aforesaid, with respect to the Common Stock, the Series C
     Stockholders and Series E Stockholders as a class shall be
     entitled to share ratably (calculated with respect to such Series
     C Stock or Series E Stock as provided in the next sentence) with
     the Common Stockholders in all remaining assets of the
     Corporation available for distribution to its stockholders. For
     purposes of calculating the amount of any payment to be paid upon
     any such Liquidation, each share of such Series C Stock or Series
     E Stock shall be deemed to be that number of shares (including
     fractional shares) of Common Stock into which it is then
     convertible, rounded to the nearest one-tenth of a share.

               A.4(f)(i) In the event of and simultaneously with the
     closing of an Event of Sale (as hereinafter defined), the
     Corporation shall (unless waived pursuant to Section A.4(f)(v) or
     otherwise prevented by law) redeem all of the shares of Series C
     Stock and Series E Stock then outstanding for a cash amount per
     share determined as set forth herein (the "Special Liquidation
     Price," said redemption being referred to herein as a "Special
     Liquidation"). For all purposes of this Section A.4(f), the
     Special Liquidation Price shall be equal to that amount per share
     which would be received by each Series C Stockholder and Series E
     Stockholder if, in connection with an Event of Sale, all
     consideration paid in exchange for the assets or the shares of
     capital stock (as the case may be) of the Corporation were
     actually paid to and received by the Corporation and the
     Corporation were immediately thereafter liquidated and its assets
     distributed pursuant to Section A.4(a) through (e) hereof. To the
     extent that one or more redemptions (as described in Section A.5
     hereof) and/or Special Liquidations are occurring concurrently,
     the Special Liquidation under this Section A.4(f) shall be deemed
     to occur first. The date upon which the Special Liquidation shall
     occur is sometimes referred to herein as the "Special Liquidation
     Date".

               A.4(f)(ii) At any time on or after the Special
     Liquidation Date, a Series C Stockholder and Series E Stockholder
     shall be entitled to receive the Special Liquidation Price for
     each such share of Series C Stock and Series E Stock owned by
     such holder. Subject to the provisions of Section A.4(f)(iii)
     hereof, payment of the Special Liquidation Price will be made
     upon actual delivery to the Corporation or its transfer agent of
     the certificate representing such shares of Series C Stock or
     Series E Stock, respectively.
<PAGE>

               A.4(f)(iii) If on the Special Liquidation Date less
     than all the shares of Series C Stock and Series E Stock then
     outstanding may be legally redeemed by the Corporation, the
     Special Liquidation shall be pro rata with respect to such
                                  --- ----
     Series C Stock and Series E Stock based upon the number of
     outstanding shares of Series C Stock or Series E Stock then owned
     by each holder thereof.

               A.4(f)(iv) On and after any Special Liquidation Date,
     all rights in respect of the shares of Series C Stock and Series
     E Stock to be redeemed shall cease and terminate except the right
     to receive the applicable Special Liquidation Price as provided
     herein, and such shares of Series C Stock and Series E Stock
     shall no longer be deemed to be outstanding, whether or not the
     certificates representing such shares of Series C Stock and/or
     Series E Stock have been received by the Corporation; provided,
                                                           --------
     however, that, if the Corporation defaults in the payment of the
     -------
     Special Liquidation Price with respect to any Series C Stock or
     Series E Stock, the rights of the holder(s) thereof with respect
     to such shares of Series C Stock and Series E Stock shall
     continue until the Corporation cures such default.

               A.4(f)(v) Anything contained herein to the contrary
     notwithstanding, the provisions of this Section A.4(f) may be
     waived by the holders of 66 2/3% in voting power of the share of
     Series C Stock and Series E Stock then outstanding, voting
     together as a class, by delivery of written notice of waiver to
     the Corporation prior to the closing of any Event of Sale, in
     which event the Corporation shall not redeem any shares of Series
     C Stock or Series E Stock pursuant to this Section A.4(f).

               A.4(t)(vi) Any notice required to he given to the
     holders of shares of Series C Stock pursuant to Section A.7(f)
     hereof in connection with an Event of Sale shall include a
     statement by the Corporation of (A) the Special Liquidation Price
     which each Series C Stockholder shall be entitled to receive upon
     the occurrence of a Special Liquidation under this Section A.4(f)
     and (B) the extent to which the Corporation will, if at all, be
     legally prohibited from paying each holder of Series C Stock the
     Special Liquidation Price.

               A.4(f)(vii) For purposes of this Section A.4(f), an
     "Event of Sale" shall mean (A) the merger or consolidation of the
     Corporation into or with another corporation, partnership, joint
     venture, trust or other entity, or the merger or consolidation of
     any corporation into or with the Corporation (in which
     consolidation or merger the stockholders of the Corporation
     receive distributions of cash or securities as a result of such
     consolidation or merger in complete exchange for their shares of
     capital stock of the Corporation), or (B) the sale or other
     disposition of all or substantially all the assets of the
     Corporation, unless, upon consummation of such merger,
     consolidation or sale of assets, the holders of voting
<PAGE>

          securities of the Corporation immediately prior to such
          transaction continue to own directly or indirectly not less than
          a majority of the voting power of the surviving corporation."

          other Parity Securities in accordance with their respective
          liquidation preferences, an amount in cash equal to $4.50 per share

          amount shall be subject to equitable adjustment whenever there shall
          occur a stock dividend, distribution, combination of shares,
          reclassification or other similar event with respect to the Series E
          Stock and, as so adjusted from time to time, is hereinafter referred

          all other Parity Securities of all amounts distributable to them under
          Section 3(a)(i) hereof and under the Certificate of Incorporation,

          liquidation preference to

          which each is entitled among Series E Stockholders and the holders of
          all such other Parity Securities. For purposes of calculating the
          amount of any payment to be paid upon any such Liquidation Event, each
          share of such Series E Stock shall be deemed to be that number of
          shares (including fractional shares) of Common Stock into which it is
          then convertible, rounded to the nearest one- tenth of a share.

               (iii) After payment shall have been made to the Series E
          Stockholders and all such other Parity Securities of the full amount
          to which they shall be entitled pursuant to (3)(a)(i) above and in the
          Certificate of Incorporation, the holders of Series C Stock then
          outstanding (the "Series C Stockholders") and Series E Stockholders,
          as a class, shall be entitled to receive an amount equal (and in like
          kind) to the aggregate preferential amount, if any, fixed for any
          class or series of Junior Securities (other than Common Stock) in
          descending order of priority, which amount shall be distributed among
          the Series C Stockholders and Series E Stockholders in an equal amount
          per share of the Series C Stock and Series E Stock then outstanding,
          pro rata with the holders of such Junior Securities. If, upon any
          Liquidation Event, the assets of the Corporation available for
          distribution to its stockholders shall be insufficient to pay the
          Series C Stockholders, Series E Stockholders and Junior Securities
          (other than the Common Stock) the full amounts to which they shall be
          entitled pursuant to the next preceding sentence, the Series C
          Stockholders and Series E Stockholders and such other class or series
          of Junior Securities shall share ratably in any distribution of assets
          according to the respective preferential amounts fixed for the Series
          C Stock and Series E Stock (pursuant to Section 2(a)(i)) and such
          Junior Securities which would be payable in respect of the shares held
          by them upon such distribution if all amounts payable on or with
          respect to such shares were paid in full.

               (iv) After payment shall have been made to the Series C
          Stockholders and Series E Stockholders of the full amount to which
          they shall be entitled as aforesaid, the Series C Stockholders and the
          Series E Stockholders as a class shall be entitled to share ratably
          (calculated with respect to such Series C Stock and Series E Stock as
          provided in the next sentence) with the Common Stockholders in all
          remaining assets of the Corporation available for distribution to its
          stockholders. For purposes of calculating the amount of any payment to
          be paid upon any such Liquidation Event, each share of such Series C
          Stock and Series E Stock shall be deemed to be that number of shares
          (including fractional shares) of Common Stock into which it is then
          convertible, rounded to the nearest one-tenth of a share.

               (v) (A) In the event of and simultaneously with the closing of an
          Event of Sale (as hereinafter defined), the Corporation shall (unless
          waived pursuant to Section (v)(E) or otherwise prevented by law)
          redeem all of the shares of Series C Stock and Series E Stock then
          outstanding for a cash amount per share determined as set forth herein
          (the "Special Liquidation Price," said redemption being referred to
          herein as a "Special Liquidation"). For all purposes of this Section
          3(a)(v), the

                                       3
<PAGE>

          Special Liquidation Price shall be equal to that amount per share
          which would be received by each holder of Series E Stock and Series C
          Stock if, in connection with an Event of Sale, all consideration paid
          in exchange for the assets or the shares of capital stock (as the case
          may be) of the Corporation were actually paid to and received by the
          Corporation and the Corporation were immediately thereafter liquidated
          and its assets distributed pursuant to Section 3(a)(i) through (iv)
          hereof. To the extent that one or more redemptions (as described in
          Section 7 hereof) and/or Special Liquidations are occurring
          concurrently, the Special Liquidation under this Section 3(v)(A) shall
          be deemed to occur first. The date upon which the Special Liquidation
          shall occur is sometimes referred to herein as the "Special
          Liquidation Date."

               (B) At any time on or after the Special Liquidation Date, each
          holder of Series E Stock and Series C Stock shall be entitled to
          receive the Special Liquidation Price for each such share of Series E
          Stock and Series C Stock owned by such holder. Subject to the
          provisions of Section 3(a)(v)(B) hereof, payment of the Special
          Liquidation Price will be made upon actual delivery to the Corporation
          or its transfer agent of the certificate representing such shares of
          Series E Stock and Series C Stock.

               (C) If on the Special Liquidation Date less than all the shares
          of Series E Stock and Series C Stock then outstanding may be legally
          redeemed by the Corporation, the Special Liquidation shall be pro rata
          with respect to such Series E Stock and Series C Stock based upon the
          number of outstanding shares of Series E Stock and Series C Stock then
          owned by each holder thereof.

               (D) On and after any Special Liquidation Date, all rights in
          respect of the shares of Series E Stock and Series C Stock to be
          redeemed shall cease and terminate except the right to receive the
          applicable Special Liquidation Price a provided herein, and such
          shares of Series E Stock and Series C Stock shall no longer be deemed
          to be outstanding, whether or not the certificates representing such
          shares of Series E Stock and Series C Stock have been received by the
          Corporation; provided, however, that, if the Corporation defaults in
          the payment of the Special Liquidation Price with respect to any
          Series E Stock and Series C Stock, the rights of the holder(s) thereof
          with respect to such shares of Series E Stock and Series C Stock shall
          continue until the Corporation cures such default.

               (E) Anything contained herein to the contrary notwithstanding,
          the provisions of this Section 3(a)(v) may be waived by the holders of
          66-2/3% in voting power of the shares of Series C Stock and Series E
          Stock then outstanding, voting together as a class, by delivery of
          written notice of waiver to the Corporation prior to the closing of
          any Event of Sale, in which event the Corporation shall not redeem any
          shares of Series C Stock or Series E Stock pursuant to this Section
          3(a)(v).

                                       4

               (F) Any notice required to be given to the Series C Stockholders
          and Series E Stockholders pursuant to Section 3(a)(v) hereon in
          connection with an Event of Sale shall include a statement by the
          Corporation of (1) the Special Liquidation Price which each holder of
          Series C Stock and Series E Stock shall be entitled to receive upon
          the occurrence of a Special Liquidation under this Section 3(a)(v) and
          (2) the extent to which the Corporation will, if at all, be legally
          prohibited from paying each Series C Stockholder and Series E
          Stockholder the Special Liquidation Price.

               (G) For purposes of this Section 2(a)(v), an "Event of Sale"
          shall mean (A) the merger or consolidation of the Corporation into or
          with another corporation, partnership, joint venture, trust or other
          entity, or the merger or consolidation of any corporation into or with
          the Corporation (in which consolidation or merger the stockholders of
          the Corporation receive distributions of cash or securities as a
          result of such consolidation or merger in complete exchange for their
          shares of capital stock of the Corporation), or (B) the sale or other
          disposition of all or substantially all the assets of the Corporation,
          unless, upon consummation of such merger, consolidation or sale of
          assets, the holders of voting securities of the Corporation
          immediately prior to such transaction continue to own directly or
          indirectly not less than a majority of the voting power of the
          surviving corporation. An "Event of Sale" shall not include any
          reorganization, merger or consolidation involving (1) only a change in
          the state of incorporation of the Corporation, (2) a merger of the
          Corporation with or into a wholly-owned subsidiary of the Corporation
          which is incorporated in the United States of America, or (3) an
          acquisition by merger, reorganization or consolidation, in which the
          Corporation is substantively the surviving corporation and operates as
          a going concern, of another corporation which is incorporated in the
          United States of America and which is engaged in a business similar to
          or related to the business of the Corporation and which does not
          involve a change in the terms of the Preferred Stock or of the Common
          Stock.

     4.   Conversion. The Series E Stockholders shall have conversion
rights as follows (the "Conversion Rights"):

          (a) Right to Convert; Conversion Price. Subject to Section 4(b), each
share of Series E Stock shall be convertible, without the payment of any
additional consideration by the holder thereof and at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the Corporation or any transfer agent for the Series E Stock, into such number
of fully paid and non-assessable shares of Common Stock as is determined by
dividing the Original Series Issue Price by the Conversion Price, determined as
hereinafter provided, in effect at the time of conversion. As used herein, the
term "Conversion Price" shall initially mean $4.50 per share. Such initial
Conversion Price shall be subject to adjustment, in order to adjust the number
of shares of Common Stock into which the Series E Stock is convertible, as
hereinafter provided.

          Any Series E Stockholder who exercises the right to convert shares of
Series E Stock into shares of Common Stock, pursuant to this Section 4 shall be
entitled to payment of all

                                       5
<PAGE>

declared but unpaid dividends payable with respect to such Series E Stock
pursuant to Section 6 herein, up to an including the date of conversion.


          (b) Mechanics of Conversion. Before any Series E Stockholder shall be
entitled to convert the same into full shares of Common Stock, such holder shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the Corporation or of any transfer agent for the Series E Stock, and shall
give written notice to the Corporation at such office that such holder elects to
convert the same and shall state therein (i) the name of such holder or the name
or names of the nominees of such holder in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued and (ii) the
number of such shares to be converted into Common Stock. No fractional shares of
Common Stock shall be issued upon conversion of any shares of Series E Stock. In
lieu of any fractional shares of Common Stock to which the holder would
otherwise be entitled, the Corporation shall pay cash equal to such fraction
multiplied by the then effective Conversion Price. The Corporation shall, as
soon as practicable thereafter, issue and deliver at such office to such Series
E Stockholder, or to such holder's nominee or nominees, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled as aforesaid, together with cash in lieu of any fraction of a share.
Upon conversion of only a portion of the number of shares covered by a Series E
Stock certificate, the Corporation shall issue and deliver to or upon written
order of the holder of such Series E Stock Certificate, at the expense of the
Corporation, a new certificate covering the number of shares of the Series E
Stock representing the unconverted portion of the Series E Stock certificate,
which new certificate shall entitle the holder thereof to all the rights, power
and privileges of a holder of such shares. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series E Stock to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock on such date.

          (c)  Automatic Conversion.

               (i) Each share of Series E Stock shall automatically be converted
          into shares of Common Stock at the then effective Conversion Price
          upon the closing of a firm commitment underwritten public offering
          pursuant to an effective registration statement under the Securities
          Act of 1933, as amended, covering the offer and sale of Common Stock
          for the account of the Corporation to the public with a public
          offering price of not less than $15.00 per share (as adjusted) and
          which results in an aggregate price to the public of not less than
          $25,000,000 (a "Qualified Initial Public Offering").


               (ii) Upon the occurrence of a Qualified Initial Public Offering,
          all shares of Series E Stock shall be converted automatically into
          shares of Common Stock without any further action by any holder of
          such shares and whether or not the certificate or certificates
          representing such shares are surrendered to the Corporation or the
          transfer agent for the Series E Stock; provided, however, that the
          Corporation shall not be obligated to issue a certificate or
          certificates evidencing the shares of Common Stock into which such
          shares of Series E Stock were converted unless the certificate or
          certificates representing such shares of Series E Stock being
          converted are either delivered to the Corporation or the transfer
          agent of the Series E Stock, or the holder

                                       6
<PAGE>

          notifies the Corporation or such transfer agent that such certificate
          or certificates have been lost, stolen, or destroyed and executes and
          delivers an agreement satisfactory to the Corporation to indemnify the
          Corporation from any loss incurred by it in connection therewith and,
          if the Corporation so elects, provides an appropriate indemnity.

               (iii) Upon the automatic conversion of Series E Stock, each
          Series E Stockholder shall surrender the certificate or certificates
          representing such holder's shares of Series E Stock at the office of
          the Corporation or of the transfer agent for the Series E Stock.
          Thereupon, there shall be issued and delivered to such holder,
          promptly at such office and in such holder's name as shown on such
          surrendered certificate or certificates, a certificate or certificates
          for the number of shares of Common Stock into which the shares of
          Series E Stock surrendered were convertible on the date on which such
          automatic conversion occurred. No fractional shares of Common Stock
          shall be issued upon the automatic conversion of Series E Stock. In
          lieu of any fractional shares of Common Stock to which the holder
          would otherwise be entitled, the Corporation shall pay cash equal to
          such fraction multiplied by the then effective Conversion Price.

          (d)  Adjustments to Conversion Price for Diluting Issues.

               (i) Special Definitions.  For purposes of this Section 4(d), the

                    (B) "Original Issue Date" shall mean, with respect to the
               Series E Stock, the date on which the first share of such series
               of Series E Stock was issued.

                    (C) "Convertible Securities" shall mean any evidences of
               indebtedness, shares (other than Series E Stock) or other
               securities directly or indirectly convertible into or
               exchangeable for Common Stock.

                    (D) "Current Market Price" shall mean the Current Market
               Price at any date of one share of Common Stock shall be deemed to
               be the average of the daily closing prices for the 30 consecutive
               business days ending on the fifth (5th) business day before the
               day in question (as adjusted for any stock dividend, split-up,
               combination or reclassification that took effect during such 30-
               business-day period) as follows:

                         (I) If the Common Stock is listed or admitted for
                    trading on a national securities exchange, then the closing
                    price for each day shall be the last reported sales price
                    regular way or,

                                       7
<PAGE>

                    in case no reported sales took place on such day, the
                    average of the last reported bid and asked prices regular
                    way, in either case on the principal national securities
                    exchange on which the Common Stock is listed or admitted to
                    trading.

                         (II) If the Common Stock is not at the time listed or
                    admitted for trading on any such exchange, then such price
                    as shall be equal to the last reported sales price, or if
                    there is no such sales price, the average of the last
                    reported bid and asked prices, as reported by the National
                    Association of Securities Dealers Automated Quotation System
                    ("Nasdaq") on such day.

                         (III) If the Common Stock is not at the time quoted on
                    the Nasdaq, then such price shall be equal to the last
                    reported bid and asked prices on such day as reported by the
                    National Quotation Bureau, Inc., or any similar reputable
                    quotation and reporting service, if such quotation is not
                    reported by the National Quotation Bureau, Inc.

                         (IV) If the Common Stock is not traded in such manner
                    that the quotations referred to in this definition are
                    available for the period required hereunder, then the
                    Current Market Price shall be the fair market value of such
                    share, as determined in good faith by a majority of the
                    entire Board of Directors.

          is convertible shall be made by adjustment in the Conversion Price in
          respect of the issuance of Additional Shares of Common Stock or
          otherwise unless (i) the consideration per share for an Additional
          Share of Common Stock issued or deemed to be issued by the Corporation
          is less than the Conversion Price in effect on the date of, and
          immediately prior to, the issue of such Additional Shares of Common
          Stock and (ii) prior to such issuance, the Corporation fails to
          receive written notice from the holders of at least a majority of the
          then outstanding shares of Series E Stock agreeing that no such
          adjustment shall be made as the result of the issuance of Additional
          Shares of Common Stock.

               (iii) Issue of Securities Deemed Issue of Additional Shares.

                    (A) Options and Convertible Securities. In the event the
               Corporation at any time after the Original Issue Date shall issue
               any Options or Convertible Securities or shall fix a record date
               for the

                                       9
<PAGE>

               determination of holders of any class of securities entitled to
               receive any such Options or Convertible Securities, then the
               maximum number of shares (as set forth in the instrument relating
               thereto without regard to any provisions contained therein for a
               subsequent adjustment of such number) of Common Stock issuable
               upon the exercise of such Options or, in the case of Convertible
               Securities and Options therefor, the conversion or exchange of
               such Convertible Securities, shall be deemed to be Additional
               Shares issued as of the time of such issue or, in case such a
               record date shall have been fixed, as of the close of business on
               such record date, provided that Additional Shares shall not be
               deemed to have been issued unless the consideration per share
               (determined pursuant to Section 4(d)(v) hereof) of such
               Additional Shares would be less than the Conversion Price in
               effect on the date of and immediately prior to such issue, or
               such record date, as the case may be, and provided, further, that
               in any such case in which Additional Shares are deemed to be
               issued:


                    (I) No further adjustment in the Conversion Price shall be
               made upon the subsequent issue of Convertible Securities or
               shares of Common Stock upon the exercise of such Options or
               conversion or exchange of such Convertible Securities;

                    (II) If such Options or Convertible Securities by their
               terms provide, with the passage of time or otherwise, for any
               increase in the consideration payable to the Corporation, or
               decrease in the number of shares of Common Stock issuable upon
               the exercise, conversion or exchange thereof, the Conversion
               Price computed upon the original issue thereof (or upon the
               occurrence of a record date with respect thereto), and any
               subsequent adjustments based thereon, shall, upon any such
               increase or decrease becoming effective, be recomputed to reflect
               such increase or decrease insofar as it affects such Options or
               the rights of conversion or exchange under such Convertible
               Securities;

                    (III) Upon the expiration of any such Options or any rights
               of conversion or exchange under such Convertible Securities which
               shall not have been exercised, the Conversion Price computed upon
               the original issue thereof (or upon the occurrence of a record
               date with respect thereto), and any subsequent adjustments based
               thereon, shall, upon such expiration, be recomputed as if:

                         (a) In the case of Convertible Securities or Options
                    for Common Stock, the only Additional Shares issued were the
                    shares of Common Stock, if any, actually issued upon the
                    exercise of such Options or the conversion or exchange of
                    such Convertible Securities and the consideration received
                    therefor was the consideration actually received by the
                    Corporation for the issue of all such Options, whether or
                    not exercised, plus the consideration actually received by
                    the Corporation upon such

                                       10
<PAGE>

                    exercise, or for the issue of all such Convertible
                    Securities which were actually converted or exchanged, plus
                    the additional consideration, if any, actually received by
                    the Corporation upon such conversion or exchange; and

                         (b) In the case of Options for Convertible Securities,
                    only the Convertible Securities, if any, actually issued
                    upon the exercise thereof were issued at the time of issue
                    of such Options, and the consideration received by the
                    Corporation for the Additional Shares of Common Stock deemed
                    to have been then issued was the consideration actually
                    received by the Corporation for the issue of all such
                    Options, whether or not exercised, plus the consideration
                    deemed to have been received by the Corporation (determined
                    pursuant to Section 4(d)(v)) upon the issue of the
                    Convertible Securities with respect to which such Options
                    were actually exercised;

               (IV) No readjustment pursuant to clause (II) or (III) above shall
          have the effect of increasing the Conversion Price to an amount which
          exceeds the lower of (a) the Conversion Price immediately prior to the
          original adjustment, or (b) the Conversion Price that would have
          resulted from any issuance of Additional Shares of Common Stock
          between the original adjustment date and such readjustment date;

               (V) In the case of any Options which expire by their terms not
          more than 30 days after the date of issue thereof, no adjustment of
          the Conversion Price shall be made until the expiration or exercise of
          all such Options, whereupon such adjustment shall be made in the same
          manner provided in clause (III) above; and

               (VI) If such record date shall have been fixed and such Options
          or Convertible Securities are not issued on the date fixed therefor
          (the "Option Issue Date"), the adjustment previously made in the
          Conversion Price which became effective on such record date shall be
          canceled as of the close of business on the Option Issue Date, and
          thereafter the Conversion Price shall be adjusted pursuant to this
          Section 4(d)(iii) as of the actual date of their issuance.

          (B) Stock Dividends, Stock Distributions and Subdivisions. In the
     event the Corporation at any time or from time to time after the Original
     Issue Date shall declare or pay any dividend or make any other distribution
     on the Common Stock payable in Common Stock or effect a subdivision of the
     outstanding shares of Common Stock (by reclassification or otherwise than
     by payment of a dividend in Common Stock), then and in any such event,
     Additional Shares shall be deemed to have been issued:

                                       11
<PAGE>

               (I) In the case of any such dividend or distribution, immediately
          after the close of business on the record date for the determination
          of holders of any class of securities entitled to receive such
          dividend or distribution, or

               (II) In the case of any such subdivision, at the close of
          business on the date immediately prior to the date upon which
          corporate action becomes effective.

          If such record date shall have been fixed and no part of such dividend
     shall have been paid on the date fixed therefor ("Dividend Payment Date"),
     the adjustment previously made for the Conversion Price which became
     effective on such record date shall be canceled as of the close of business
     on such Dividend Payment Date, and thereafter the Conversion Price shall be
     adjusted pursuant to this Section 4(d)(iii) as to the time of actual
     payment of such dividend.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
          Shares.

          (A) In the event the Corporation shall issue Additional Shares
     (including, without limitation, Additional Shares deemed to be issued
     pursuant to Section 4(d)(iii) but excluding Additional Shares deemed to be
     issued pursuant to Section 4(d)(iii)(B), which event is dealt with in
     Section 4(d)(vi) hereof), without consideration or for a consideration per
     share less than the applicable Conversion Price in effect on the date of
     and immediately prior to such issue, then and in such event, such
     Conversion Price shall be reduced, concurrently with such issue in order to
     increase the number of shares of Common Stock into which the Series E Stock
     is convertible, to a price (calculated to the nearest cent) determined by
     multiplying such Conversion Price by a fraction, the numerator of which
     shall be (I) the number of shares of Common Stock outstanding immediately
     prior to such issue (including shares of Common Stock exercise or
     conversion of any outstanding Option or Convertible Securities) plus (II)
     the number of shares of Common Stock which the aggregate consideration
     received or deemed to have been received by the Corporation for the total
     number of Additional Shares so issued would purchase at such Conversion
     Price, and the denominator of which shall be (I) the number of shares
     outstanding immediately prior to such issue (including shares of Common
     Stock exercise or conversion of any outstanding Option or Convertible
     Securities) plus (II) the number of Additional Shares so issued or deemed
     to be issued.

          (B) Notwithstanding anything to the contrary contained herein, the
     applicable Conversion Price in effect at the time Additional Shares are
     issued or deemed to be issued shall not be reduced pursuant to

                                       12
<PAGE>

     Section 4(d)(iv)(A) hereof at such time if the amount of such reduction
     would be an amount less than $0.001, but any such amount shall be carried
     forward and reduction with respect thereto made at the time of and together
     with any subsequent reduction which, together with such amount and any
     other amount or amounts so carried forward, shall aggregate $0.001 or more.

     (v) Determination of Consideration. For purposes of this Section 4(d), the
consideration received by the Corporation for the issue of any Additional Shares
shall be computed as follows:

          (A) Cash and Property.  Such consideration shall:

               (I) Insofar as it consists of cash, be computed at the aggregate
          amounts of cash received by the Corporation excluding amounts paid or
          payable for accrued interest or accrued dividends;

               (II) Insofar as it consists of property other than cash, be
          computed at the fair market value thereof at the time of such issue,
          as determined in good faith by the Board of Directors; provided,
          however, that such fair market value shall not exceed the aggregate
          Current Market Price of the Additional Shares being issued, less any
          cash consideration paid for such Shares; and

               (III) In the event that Additional Shares are issued together
          with other shares or securities or other assets of the Corporation for
          consideration which covers both, be the proportion of such
          consideration so received, computed as provided in clauses (I) and
          (II) above, as determined in good faith by the Board of Directors.

          (B) Options and Convertible Securities. The consideration per share
     received by the Corporation for Additional Shares deemed to have been
     issued pursuant to Section 4(d)(iii)(A), relating to Options and
     Convertible Securities, shall be determined by dividing (I) the total
     amount, if any, received or receivable by the Corporation as consideration
     for the issue of such Options or Convertible Securities, plus the minimum
     aggregate amount of additional consideration (as set forth in the
     instruments relating thereto, without regard to any provision contained
     therein for a subsequent adjustment of such consideration) payable to the
     Corporation upon the exercise of such Options or the conversion or exchange
     of such Convertible Securities, or in the case of Options for Convertible
     Securities, the exercise of such Options for Convertible Securities and the
     conversion or exchange of such Convertible Securities, by (II) the maximum
     number of shares of Common Stock (as set forth in the instruments relating
     thereto, without regard to any provision contained therein for a subsequent
     adjustment of such number) issuable upon the exercise of such Options or
     the conversion or exchange of such Convertible Securities.

                                       13

          (vi) Adjustment for Dividends, Distributions, Subdivisions,
     Combinations or Consolidations of Common Stock.

               (A) Stock Dividends, Distributions or Subdivisions. In the event
          the Corporation shall issue Additional Shares pursuant to Section
          4(d)(iii)(B) in a stock dividend, stock distribution or subdivision,
          the Conversion Price in effect immediately prior to such stock
          dividend, stock distribution or subdivision shall, concurrently with
          the effectiveness of such stock dividend, stock distribution or
          subdivision, be proportionately decreased.


               (B) Combinations or Consolidations. In the event the outstanding
          shares of Common Stock shall be combined or consolidated, by
          reclassification or otherwise, into a lesser number of shares of
          Common Stock, the Conversion Price in effect immediately prior to such
          combination or consolidation shall, concurrently with the
          effectiveness of such combination or consolidation, be proportionately
          increased.

          (vii) Capital Reorganization, Merger or Sale of Assets. If at any time
     or from time to time there shall be a capital reorganization of the Common
     Stock (other than a subdivision, combination, recapitalization,
     reclassification or exchange of shares provided for elsewhere in this
     Section 4) or a consolidation or merger of the Corporation, or a sale of
     all or substantially all of the assets of the Corporation, (other than a
     merger, consolidation or sale of all or substantially all of the assets of
     the Corporation in a transaction in which the shareholders of the
     Corporation immediately prior to the transaction possess more than 50% of
     the voting securities of the surviving entity (or parent, if any)
     immediately after the transaction), then, as a part of and as a condition
     to such transaction, provision shall be made so that the holders of shares
     of the Series E Stock shall thereafter be entitled to receive upon
     conversion of the shares of the Series E Stock the same kind and amount of
     stock or other securities or property (including cash) of the Corporation,
     or of the successor corporation resulting from such transaction, to which
     such holder would have been entitled if such holder had converted its
     shares of the Series E Stock immediately prior to the effective time of
     such transaction. In any such case, appropriate adjustment shall be made in
     the application of the provisions of this Section 4 to the end that the
     provisions of this Section 4 (including adjustment of the Conversion Price
     then in effect and the number of shares of Common Stock or other securities
     issuable upon conversion of the shares of the Series E Stock) shall be
     applicable after such transaction in as nearly equivalent manner as may be
     reasonably practicable.

     In the case of a transaction to which both this Subsection 4(d)(vii) and
Subsection 3(a)(v) hereof apply, the holders of at least 66-2/3% of the
outstanding shares of the Series E Stock and Series C Stock, voting together as
a class, upon the occurrence of a transaction shall have the option to elect
treatment either under this Subsection 4(d)(vii) or under Subsection 3(a)(v)
hereof, notice of which election shall be given in writing to the Corporation
not less than five (5) business days prior to the

                                       14
<PAGE>

effective date of such transaction. If no such election is timely made, the
provisions of Subsection 3(b) and not of this Subsection 4(d)(vii) shall apply.

     The provisions of this Subsection 4(d)(vii) shall not apply to any
reorganization, merger or consolidation involving (1) only a change in the state
of incorporation of the Corporation, (2) a merger of the Corporation with or
into a wholly-owned subsidiary of the Corporation which is incorporated in the
United States of America, or (3) an acquisition by merger, reorganization or
consolidation, in which the Corporation is substantively the surviving
corporation and operates as a going concern, of another corporation which is
incorporated in the United States of America and which is engaged in a business
similar to or related to the business of the Corporation and which does not
involve a change in the terms of the Series E Stock or of the Common Stock.

          (viii) In any case in which the provisions of this Section 4(d) shall
     require that an adjustment shall become effective immediately after a
     record date for an event, the Corporation may defer until the occurrence of
     such event (A) issuing to the holder of any shares of Series E Stock
     converted after such record date and before the occurrence of such event
     the additional shares of capital stock issuable upon such conversion by
     reason of the adjustment required by such event over and above the shares
     of capital stock issuable upon such conversion before giving effect to such
     adjustment, and (B) paying to such holder any cash amounts in lieu of
     fractional shares pursuant to Section 4(c)(iii) hereof; provided, however,
     that the Corporation shall deliver to such holder a due bill or other
     appropriate instrument evidencing such holder's right to receive such
     additional shares, and such cash, upon the occurrence of the event
     requiring such adjustment.


     (e) No Impairment. The Corporation shall not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation but shall at
all times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of Series E
against impairment.

     (f) Certificate as to Adjustments. Upon the occurrence of each adjustment
or readjustment of the Conversion Price pursuant to this Section 4, the
Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each affected
Stockholder, a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any affected
Series E Stockholder furnish to such holder a like certificate setting forth (i)
such adjustments and readjustments, (ii) the Conversion Price at the time in
effect, and (iii) the number of shares of Common Stock and the amount, if any,
of other property which at the time would be received upon conversion of each
share of Series E Stock.

     (g) Notices of Record Date. In the event of any taking by the Corporation
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who

                                       15
<PAGE>

are entitled to receive any dividend (other than a cash dividend which is the
same as cash dividends paid in previous quarters) or other distribution, the
Corporation shall mail to each Series E Stockholder at least twenty (20) days
prior to such record date a notice specifying the date on which any such record
is to be taken for the purpose of such dividend or distribution.

     (h) Common Stock Reserved. The Corporation shall reserve and keep available
out of its authorized but unissued Common Stock such number of shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series E Stock.

     (i) Status of Common Stock. All shares of Common Stock which may be issued
in connection with the conversion provisions set forth herein will, upon
issuance by the Corporation, by validly issued, fully paid and nonassessable,
not subject to any preemptive or similar rights and free from all taxes, liens
or charges with respect thereto created or imposed by the Corporation.

     (j) Special Notice. In the event the Corporation shall propose to take any
action of the types described in Section 3(a)(v)(F), 4(d)(iv)(A), 4(d)(vi)(A) or
4(d)(vii) hereof, or any other Event of Sale, the Corporation shall give notice
to each Series E Stockholder in the manner set forth in Section 4(f) hereof,
which notice shall specify the record date, of any, with respect to any such
action and the date on which such action is to take place. Such notice shall
also set forth such facts with respect thereto as shall be reasonably necessary
to indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the Conversion Price with respect to the Series E
Stock, and the number, kind or class of shares of other securities or property
which shall be deliverable or purchasable upon each conversion of Series E
Stock. In the case of any action that would require the fixing of a record date,
such notice shall be given at least 20 days prior to the record date so fixed,
and in the case of any other action, such notice shall be given at least 30 days
prior to the taking of such proposed action.

     (k) Certain Taxes. The Corporation shall pay any issue or transfer taxes
payable in connection with the conversion of any shares of Series E Stock,
provided, however, that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer to a name other than that of the
holder of such Series E Stock.

     (l) Closing of Books. The Corporation shall at no time close its transfer
books against the transfer of any Series E Stock, or of any shares of Common
Stock issued or issuable upon the conversion of any shares of Series E Stock in
any manner which interferes with the timely conversion or transfer of such
Series E Stock, unless, at the request of the Company or an underwriter, the
holders of the Series E Stock shall have agreed not to sell or otherwise
transfer or dispose of any Common Stock (or other securities) of the Company
held by such holders during a period not to exceed one hundred and eighty (180)
days following the effective date of a registration statement of the Company
filed under the Securities Act, in which case the Company may impose stop-
transfer instructions with respect to the shares (or securities) subject to the
foregoing restriction until the end of said period.

     (m) Miscellaneous. If a state of facts shall occur that, without being
specifically controlled by the provisions of this Section 4, would not fairly
protect the conversion rights of the holders of the Series E Stock in accordance
with the essential intent and principles of such provisions,

                                       16
<PAGE>

then the Board of Directors shall make up an adjustment in the application of
such provisions, in accordance with such essential intent and principles, so as
to protect such conversion rights.

     5. Voting Rights.

     (a) In addition to any other rights provided herein or by law, the Series E
Stockholders shall be entitled to vote on all matters as to which Common
Stockholders shall be entitled to vote, in the same manner and with the same
effect as such Common Stockholders. In any such vote, each share of Series E
Stock shall entitle the holder thereof to the number of votes per share that
equals the number of shares of Common Stock (including fractional shares) into
which each such share of Series E Stock is then convertible, rounded up to the
nearest one-tenth of a share.


     (b)(i) In addition to the rights specified in Section 5(a), the holders of
a majority in voting power of the Series E Stock, voting as a separate class,
shall have the exclusive right to elect two directors to the Board of Directors
of the Corporation (the "Series E Preferred Directors"). In any election of
Series E Preferred Directors pursuant to this Section 5(b), each Series E
Stockholder shall be entitled to one vote for each share of the Series E Stock
held, and no Series E Stockholder shall be entitled to cumulate its votes by
giving one candidate more than one vote per share. The exclusive voting right of
the Series E Stockholders, contained in this Section 5(b), may be exercised at a
special meeting of the Series E Stockholders called as provided in accordance
with the By-laws of the Corporation, at any annual or special meeting of the
stockholders in lieu of a meeting. The Series E Preferred Directors elected
pursuant to this Section 5(b) shall serve from the date of their election and
qualification until their successors have been duly elected and qualified.

     (ii) A vacancy in the directorships to be elected by the Series E
Stockholders (including any vacancy created on account of an increase in the
number of directors on the Board of Directors), pursuant to Section 5(b)(i), may
be filled only by a vote at a meeting called in accordance with the By-laws of
the Corporation or written consent in lieu of such meeting of (A) the holders of
at least a majority in voting power of such Series E Stock or (B) the remaining
director(s) elected by the Series E Stockholders.

     6. Dividend Rights.

     (a) The holders of Series E Stock shall be entitled to receive dividends,
if and when declared by the Board of Directors, out of funds legally available
for that purpose. The right to such dividend shall not be cumulative and no
right shall accrue on each share from the date of the original issuance of such
share, by reason of default that dividends on such shares are not declared or
paid in any prior years.

     (b) If, with the consent of the holders of at least a majority of the
outstanding Series E Stock, the Board of Directors shall declare a dividend
payable upon the then outstanding shares of Common Stock (other than a dividend
payable entirely in shares of the Common Stock of the Corporation), then the
Board of Directors shall declare at the same time a dividend upon the then
outstanding shares of Series E Stock payable at the same time as the dividend
paid on the Common Stock, in an amount equal to the amount of dividends per
share of Series E Stock as would have been payable on the largest number of
whole shares of Common Stock which each share of Series E Stock

                                       17
<PAGE>

held by each holder thereof would have received if such Series E Stock had been
converted to Common Stock pursuant to the provisions of Section 3 hereof as of
the record date for the determination of holders of Common Stock entitled to
receive such dividends.

     (c) In the event the Board of Directors shall declare a dividend payable
upon any class or series of capital stock of the Corporation other than Common
Stock, the Board of Directors shall declare at the same time a dividend upon the
then outstanding shares of Series E Stock, payable at the same time as such
dividend on such other class or series of capital stock in an amount equal to
(i) in the case of any series or class convertible into Common Stock, that
dividend per share of Series E Stock as would equal the dividend payable on such
other class or series determined as if all such shares of such class or series
had been converted to Common Stock and all shares of Series E Stock have been
converted to Common Stock on the record date for the determination of holders
entitled to receive such dividend or (ii) if such class or series of capital
stock is not convertible into Common Stock, at a rate per share of Series E
Stock determined by dividing the amount of the dividend payable on each share of
such class or series of capital stock by the original issuance price of such
class or series of capital stock and multiplying such fraction by the Base
Liquidation Price then in effect.

     (d) Upon any liquidation, dissolution or winding up of the Corporation
(within the meaning of Section 3), or redemption (within the meaning of Section
7) or conversion (within the meaning of Section 4) all declared, accrued but
unpaid dividends, to and until the date of such liquidation, dissolution,
winding up, redemption or conversion shall be paid in full in accordance with
Section 3, Section 4 or Section 7 hereof.

     (e) In connection with any dividend declared or paid hereunder, each share
of Series E Stock shall be deemed to be that number of shares (including
fractional shares) of Common Stock into which it is then convertible, rounded up
to the nearest one-tenth of a share. No fractional shares of capital stock shall
be issued as a dividend hereunder. The Corporation shall pay a cash adjustment
for any such fractional interest in an amount equal to the fair market value
thereof on the last Business Day immediately preceding the date for payment of
dividends, as determined by the Board of Directors in good faith. "Business Day"
means any date other than a Saturday, Sunday or public holiday in the state
where the principal executive officer of the Corporation is located.

     7.  Redemption.

     (a) Redemption. The Corporation shall, upon the request of the holders of
at least 66-2/3% of the then outstanding shares of Series E Stock given at any
time after December 22, 2004 and on each of the first and second anniversaries
thereof (each such date being referred to hereinafter as a "Redemption Date"),
(i) provide notice to each Series E Stockholder of such request for redemption
("Redemption Notice") and (ii) redeem from each Series E Stockholder requesting
such redemption within 20 days of such Redemption Notice, at a price equal to
the original purchase price per share plus full cumulative dividends (whether or
not earned or declared) accrued and unpaid thereon, subject to appropriate
adjustment in the event of any stock dividend, stock split, combination or other
similar recapitalization affecting such shares (the "Redemption Price"), the
following respective portions of the number of shares of Series E Stock held by
such requesting holder on the applicable Redemption Date:

                                       18
<PAGE>

                                               Portion of Shares of Series E
          Redemption Date                      Stock To Be Redeemed
          ---------------                      ---------------------
          December 22, 2004                            33-1/3%
          December 22, 2005                            66-2/3%
          December 22, 2006                               100%

        (b) Insufficient Funds. If the funds of the Corporation legally
available for redemption of Series E Stock on any Redemption Date are
insufficient to redeem the number of shares of Series E Stock required under
this Section 7 to be redeemed on such date, those funds which are legally
available will be used to redeem the maximum possible number of such shares of
Series E Stock ratably on the basis of the number of shares of Series E Stock
which would be redeemed on such date if the funds of the Corporation legally
available therefor had been sufficient to redeem all shares of Series E Stock
required to be redeemed on such date. At any time thereafter when additional
funds of the Corporation become legally available for the redemption of Series E
Stock, such funds will be used, at the end of the next succeeding fiscal
quarter, to redeem the balance of the shares which the Corporation was
theretofore obligated to redeem, ratably on the basis set forth in the preceding
sentence.

        (c) Redemption Request. Subject to Section 7(a) above, on each
Redemption Date each Series E Stockholder requesting redemption shall provide
the Corporation with a written request setting forth its desire to redeem shares
of Series E Stock. Upon receipt of any such redemption request, the Corporation
will become obligated to redeem at the time of redemption specified therein all
shares of Series E Stock specified therein (other than such shares of Series E
Stock as are duly converted pursuant to Section 4 prior to the close of business
on the fifth full day preceding the Redemption Date). In case less than all
Series E Stock represented by any certificate is redeemed in any redemption
pursuant to this Section 7, a new certificate will be issued representing the
unredeemed Series E Stock without cost to the holder thereof.

        (d) Dividends on Redeemed Shares. No share of Series E Stock shall be
entitled to any dividends declared after its Redemption Date, and on such
Redemption Date all rights of the holder of such share as a stockholder of the
Corporation by reason of the ownership of such share will cease, except the
right to receive the Redemption Price of such share, without interest, upon
presentation and surrender of the certificate representing such share, and such
share will not from and after such Redemption Date be deemed to be outstanding;
provided, however, that in the event that there is a default in payment of the
Redemption Price for any shares of Series E Stock (by reason of Section 7(b) or
otherwise), such shares shall continue to accrue dividends until such time as
the Redemption Price is paid in full.

        (e) Status of Redeemed Shares. Any shares of Series E Stock redeemed
pursuant to this Section 7 will be canceled and will not under any circumstances
be reissued, sold or transferred and the Corporation may take appropriate action
from time to time as may be necessary to reduce the authorized Series E Stock
accordingly.

     8. Protective Covenants. The Corporation shall not, without first having
obtained the affirmative vote or written consent of the holders of not less than
two-thirds of the outstanding shares

                                       19
<PAGE>

of Series E Stock (except where the vote or written consent of the holders of a
greater number of shares of the Corporation is required by law or by this
Certificate of Incorporation) (i) sell, abandon, transfer, lease or otherwise
dispose of all or substantially all of its properties or assets or assets or
properties in a single or series of related transactions in excess of 10% of the
then net worth of the Corporation, (ii) except as otherwise required by this
Certificate of Designation, declare or pay any dividend or make any distribution
with respect to shares of its capital stock (whether in cash, shares of capital
stock or other securities or property); (iii) except as otherwise required by
this Certificate of Designation or in any agreement approved by the Board of
Directors with an officer, director, employee or consultant providing for the
repurchase of any of its capital stock owned by such officer, director, employee
or consultant at the option of the Corporation, make any payment on account of
the purchase, redemption or other retirement of any share of capital stock of
the Corporation, or distribute to holders of Common Stock shares of the
Corporation's capital stock (other than Common Stock) or other securities of
other entities, evidences of indebtedness issued by the Corporation or other
entities, or other assets or options or rights; (iv) merge or consolidate with
or into, or permit any subsidiary to merge or consolidate with or into, any
other corporation, corporations or other entity or entities; (v) voluntarily
dissolve, liquidate or wind-up or carry out any partial liquidation or
distribution or transaction in the nature of a partial liquidation or
distribution; (vi) in any manner alter or change the designations, powers,
preferences, rights, qualifications, limitations or restrictions of the Series E
Stock; (vii) take any action to cause any amendment, alteration or repeal of any
of the provisions of this Certificate of Designation or the By-laws of the
Corporation, which amendment, alteration or repeal adversely affects the powers,
preferences or rights pertaining to the Series E Stock; (viii) amend or modify
any stock option plan of the Corporation or any stock option agreement or
restricted stock purchase agreement or stock restriction agreement entered into
between the Corporation and its employees, officers, directors, consultants,
contractors and/or any other signatory thereto (including, without limitation,
to accelerate the vesting schedule or exercise date or dates of any such option
or in any stock option agreement or waive or modify the Corporation's repurchase
rights with respect to any shares of the Corporation's stock issuable pursuant
to any restricted stock purchase agreement or stock restriction agreement)
except for immaterial changes either made thereto form time to time by officers
of the Corporation or approved in writing by both of the Series E Preferred
Directors.

     9. No Reissuance of Preferred Stock. No share or shares of Series E Stock
acquired by the Corporation by reason of redemption, purchase, conversion or
otherwise shall be reissued, and all such shares shall be canceled, retired and
eliminated from the shares which the corporation shall be authorized to issue.

     10. Residual Rights. All rights accruing to the outstanding shares of the
Corporation not expressly provided for in the terms of the Series E Stock shall
be vested in the Common Stock or such other class or series of stock as may be
provided in the Certificate of Incorporation.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of

     Stockholders to be redeemed on a Redemption Date in accordance with this
     Section 7(a), shall be entitled to receive the Redemption Payment in three
     equal installments, the first of which installments shall be made upon
     actual delivery to the Corporation or its transfer agent of the certificate
     or certificates representing the shares of Series E Stock to be redeemed.

          (ii) Anything contained in this Section 7(a) to the contrary
     notwithstanding, the holders of Series E Stock shall have the right,
     exercisable at any time up to the fifth

     business day prior to the close of business on a Redemption Date (unless
     the Corporation shall default in, or be legally prohibited from, paying the
     installment payment of the Redemption Price as herein provided, in which
     event such right shall be exercisable until such default is cured), to
     convert all or any part of such shares requested by such holder to be
     redeemed as herein provided into shares of Common Stock pursuant to Section
     4 of this Article. If, and to the extent, any Series E Stock so entitled to
     redemption are converted into shares of Common Stock by the holders thereof
     prior to the close of business on such Redemption Date, the total number of
     Series E Stock otherwise to be redeemed on such Redemption Date shall be
     reduced by the number of Series E Stock so converted."

thereof following such initial classification, directors elected to succeed
those directors whose terms expire shall be elected for a term of office to
expire at the third succeeding annual meeting of stockholders or special meeting
in lieu thereof after their election and until their successors are duly elected
and qualified.

     C. Subject to the rights of the holders of any series of Preferred Stock
then outstanding, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office even though less than a quorum, or by a sole remaining director.
In the event of any increase or decrease in the authorized number of directors,
(i) each director then serving as such shall nevertheless continue as a director
of the class of which he is a member until the expiration of his current term or
his prior death, retirement, removal or resignation and (ii) the newly created
or eliminated directorships resulting from such increase or decrease shall if
reasonably possible be apportioned by the Board of Directors among the three
classes of directors so as to ensure that no one class has more than one
director more than any other class. To the extent reasonably possible,
consistent with the foregoing rule, any newly created directorships shall be
added to those classes whose terms of office are to expire at the latest dates
following such allocation and newly eliminated directorships shall be subtracted
from those classes whose terms of office are to expire at the earliest dates
following such allocation, unless otherwise provided for from time to time by
resolution adopted by a majority of the directors then in office, although less
than a quorum.

     D. Advance notice of stockholder nominations for the election of directors
and of business to be brought by stockholders before any meeting of the
stockholders of the Corporation shall be given in the manner provided in the By-
Laws of the Corporation.

     E. Subject to the rights of the holders of any series of Preferred Stock
then outstanding, any director, or the entire Board of Directors, may be removed
from office at any time only for cause by the affirmative vote of the holders of
a majority of the outstanding shares of capital stock then entitled to vote at
an election of the directors. A director may be removed for cause only after a
reasonable notice and opportunity to be heard by the stockholders.

     EIGHTH: The Board of Directors is expressly empowered to adopt, amend or
repeal By-Laws of the Corporation. Any adoption, amendment or repeal of the By-
Laws of the Corporation by the Board of Directors shall require the approval of
a majority of the Board of Directors. The stockholders shall also have power to
adopt, amend or repeal the By-Laws of the Corporation; provided, that in
                                                       --------
addition to any vote of the holders of any class or series of stock of the
Corporation required by law or by this Restated Certificate of Incorporation,
the affirmative vote of the holders of at least seventy percent (70%) of the
voting power of all of the then outstanding shares of the capital stock of the
Corporation entitled to vote generally in the election of directors, voting
together as a single class, shall be required for the stockholders to adopt,
amend or repeal any provision of the By-Laws of the Corporation.

     NINTH. 1. Actions, Suits and Proceedings Other than by or in the Right of
               ---------------------------------------------------------------
the Corporation. The Corporation shall indemnify each person who was or is a
- ---------------
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful. Notwithstanding
anything to the contrary in this Article, except as set forth in Section 7
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation. Notwithstanding anything to the contrary in this Article, the
Corporation shall not indemnify an Indemnitee to the extent such Indemnitee is
reimbursed from the proceeds of insurance, and in the event the Corporation
makes any indemnification payments to an Indemnitee and such Indemnitee is
subsequently reimbursed from the proceeds of insurance, such Indemnitee shall
promptly refund such indemnification payments to the Corporation to the extent
of such insurance reimbursement.

     2. Actions or Suits by or in the Right of the Corporation. The Corporation
        ------------------------------------------------------
shall indemnify any Indemnitee who was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was, or has agreed to become, a director or officer of the
Corporation, or is or was serving, or has agreed to serve, at the request of the
Corporation, as a director, officer or trustee of, or in a similar capacity
with, another corporation, partnership, joint venture, trust or other enterprise
(including any employee benefit plan), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees) and, to the extent permitted by law, amounts paid in settlement
actually and reasonably incurred by him or on his behalf in connection with such
action, suit or proceeding and any appeal therefrom, if he acted in good faith
and in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Corporation, except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of Delaware shall determine upon application that, despite the
adjudication of



                                       6
<PAGE>

such liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses (including
attorneys' fees) which the Court of Chancery of Delaware shall deem proper.

     3. Indemnification for Expenses of Successful Party. Notwithstanding the
        ------------------------------------------------
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
          ---------------
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     4. Notification and Defense of Claim. As a condition precedent to his right
        ---------------------------------
to be indemnified, the Indemnitee must notify the Corporation in writing as soon
as practicable of any action, suit, proceeding or investigation involving him
for which indemnity will or could be sought. With respect to any action, suit,
proceeding or investigation of which the Corporation is so notified, the
Corporation will be entitled to participate therein at its own expense and/or to
assume the defense thereof at its own expense, with legal counsel reasonably
acceptable to the Indemnitee. After notice from the Corporation to the
Indemnitee of its election so to assume such defense, the Corporation shall not
be liable to the Indemnitee for any legal or other expenses subsequently
incurred by the Indemnitee in connection with such claim, other than as provided
below in this Section 4. The Indemnitee shall have the right to employ his own
counsel in connection with such claim, but the fees and expenses of such counsel
incurred after notice from the Corporation of its assumption of the defense
thereof shall be at the expense of the Indemnitee unless (i) the employment of
counsel by the Indemnitee has been authorized by the Corporation, (ii) counsel
to the Indemnitee shall have reasonably concluded that there may be a conflict
of interest or position on any significant issue between the Corporation and the
Indemnitee in the conduct of the defense of such action or (iii) the Corporation
shall not in fact have employed counsel to assume the defense of such action, in
each of which cases the fees and expenses of counsel for the Indemnitee shall be
at the expense of the Corporation, except as otherwise expressly provided by
this Article. The Corporation shall not be entitled, without the consent of the
Indemnitee, to assume the defense of any claim brought by or in the right of the
Corporation or as to which counsel for the Indemnitee shall have reasonably made
the conclusion provided for in clause (ii) above.

     5. Advance of Expenses. Subject to the provisions of Section 6 below, in
        -------------------
the event that the Corporation does not assume the defense pursuant to Section 4
of this Article of any action, suit, proceeding or investigation of which the
Corporation receives notice under this



                                       7
<PAGE>

Article, any expenses (including attorneys' fees) incurred by an Indemnitee in
defending a civil or criminal action, suit, proceeding or investigation or any
appeal therefrom shall be paid by the Corporation in advance of the final
disposition of such matter; provided, however, that the payment of such expenses
incurred by an Indemnitee in advance of the final disposition of such matter
shall be made only upon receipt of an undertaking by or on behalf of the
Indemnitee to repay all amounts so advanced in the event that it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
by the Corporation as authorized in this Article. Such undertaking shall be
accepted without reference to the financial ability of the Indemnitee to make
such repayment.

     6. Procedure for Indemnification. In order to obtain indemnification or
        -----------------------------
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the Corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses. Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines within such 60-day period that the Indemnitee did not
meet the applicable standard of conduct set forth in Section 1 or 2, as the case
may be. Such determination shall be made in each instance by (a) a majority vote
of the directors of the Corporation consisting of persons who are not at that
time parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) a majority vote of a committee of
disinterested directors designated by majority vote of disinterested directors,
whether or not a quorum, (c) a majority vote of a quorum of the outstanding
shares of stock of all classes entitled to vote for directors, voting as a
single class, which quorum shall consist of stockholders who are not at that
time parties to the action, suit or proceeding in question, (d) independent
legal counsel (who may, to the extent permitted by law, be regular legal counsel
to the Corporation), or (e) a court of competent jurisdiction.

     7. Remedies. The right to indemnification or advances as granted by this
        --------
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6. Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation. Neither the failure of the Corporation
to have made a determination prior to the commencement of such action that
indemnification is proper in the circumstances because the Indemnitee has met
the applicable standard of conduct nor an actual determination by the
Corporation pursuant to Section 6 that the Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the Indemnitee has not met the applicable standard of conduct.
The Indemnitee's expenses (including attorneys' fees) incurred in connection
with successfully establishing his right to indemnification, in whole or in
part, in any such proceeding shall also be indemnified by the Corporation.

     8. Subsequent Amendment. No amendment termination or repeal of this Article
        --------------------
or



                                       8
<PAGE>

of the relevant provisions of the General Corporation Law of Delaware or any
other applicable laws shall affect or diminish in any way the rights of any
Indemnitee to indemnification under the provisions hereof with respect to any
action, suit proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment termination or repeal.

     9. Other Rights. The indemnification and advancement of expenses provided
        ------------
by this Article shall not be deemed exclusive of any other rights to which an
Indemnitee seeking indemnification or advancement of expenses may be entitled
under any law (common or statutory), agreement or vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in any other capacity while holding office for the Corporation,
and shall continue as to an Indemnitee who has ceased to be a director or
officer, and shall inure to the benefit of the estate, heirs, executors and
administrators of the Indemnitee. Nothing contained in this Article shall be
deemed to prohibit, and the Corporation is specifically authorized to enter
into, agreements with officers and directors providing indemnification rights
and procedures different from those set forth in this Article. In addition, the
Corporation may, to the extent authorized from time to time by its Board of
Directors, grant indemnification rights to other employees or agents of the
Corporation or other persons serving the Corporation and such rights may be
equivalent to, or greater or less than, those set forth in this Article.

     10. Partial Indemnification. If an Indemnitee is entitled under any
         -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     11. Insurance. The Corporation may purchase and maintain insurance, at its
         ---------
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise (including any employee benefit plan) against any expense, liability
or loss incurred by him in any such capacity, or arising out of his status as
such, whether or not the Corporation would have the power to indemnify such
person against such expense, liability or loss under the General Corporation Law
of Delaware.

     12. Merger or Consolidation. If the Corporation is merged into or
         -----------------------
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such .merger or consolidation.

     13. Savings Clause. If this Article or any portion hereof shall be
         --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit proceeding or investigation, whether civil,



                                       9
<PAGE>

criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

     14. Definitions. Terms used herein and defined in Section 145(h) and
         -----------
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     15. Subsequent Legislation. If the General Corporation Law of Delaware is
         ----------------------
amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     TENTH: The Corporation reserves the right to amend or repeal any provision
contained in this Restated Certificate of Incorporation in the manner prescribed
by the Delaware General Corporation Law and all rights conferred upon
stockholders are granted subject to this reservation; provided that in addition
                                                      --------
to the vote of the holders of any class or series of stock of the Corporation
required by law or by this Restated Certificate of Incorporation, the
affirmative vote of the holders of shares of voting stock of the Corporation
representing at least seventy percent (70%) of the voting power of all of the
then outstanding shares of the capital stock of the Corporation entitled to vote
generally in the election of directors, voting together as a single class, shall
be required to (i) reduce the number of authorized shares of Common Stock or the
number of authorized shares of Preferred Stock set forth in Article FOURTH or
(ii) amend, alter or repeal, or adopt any provision inconsistent with, Articles
SIXTH, SEVENTH, EIGHTH, NINTH and this Article TENTH of this Restated
Certificate of Incorporation.

     ELEVENTH: Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of the Delaware General Corporation Law or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of the Delaware General
Corporation Law, order a meeting of the creditors or class of creditors, and/or
of the stockholders or class of stockholders of this Corporation, as the case
may be, to be summoned in such manner as the said court directs. If a majority
in number representing three-fourths (3/4) in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

Ladies and Gentlemen:

     We have acted as counsel to Orchid BioSciences, Inc., a Delaware
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission (the "Commission") of a Registration
Statement on Form S-1, Registration No. 333-30774 (the "Registration
Statement"), as amended, pursuant to which the Company is registering under the
Securities Act of 1933, as amended, a total of _________ shares (the "Shares")
of its common stock, $.001 par value per share (the "Common Stock").  The Shares
are to be sold to a group of underwriters (the "Underwriters") who will be
parties to an Underwriting Agreement with the Company, the form of which
Agreement will be filed as an exhibit to the Registration Statement.  All of the

            under no circumstances shall a Custom Kit convert to a Converted Kit
            if such conversion would violate the terms of the applicable
            agreement between ORCHID and such customer or customers or if such
            Custom Kit contains primers for the analysis of SNPs that are owned
            either by such customer or owned by ORCHID but limited to use by
            such customer, and are subject to restrictions on use by third
            parties (provided, however, ORCHID shall use commercially reasonable
            efforts to ensure that any primers contained in such Custom Kits are
            free of restrictions on use), and (ii) Custom Kits shall convert to
            Converted Kits on an individual basis, with reference to the
            Specifications of such Custom Kit. If, with respect to a Converted
            Kit, the CMC concludes that at the Conversion Date ORCHID has not
            recovered the [*] incurred by ORCHID in developing such Custom Kit,
            then the CMC may require AFFYMETRIX to pay a conversion fee in an
            amount not to exceed [*]) in an amount and payment schedule
            determined by the CMC. ORCHID may until the end of the sixth month
            following immediately after the Conversion Date sell its inventory

            remaining inventory of Converted Kits to AFFYMETRIX at the transfer
            price established for such Converted Kit by the CMC. Once a
            conversion occurs, the parties will negotiate reasonable commercial
            performance standards for AFFYMETRIX's sales of Converted Kits.

            (ii) The Parties hereby acknowledge and agree that all sales of
      ORCHID OEM Kits to AFFYMETRIX shall be controlled by the terms contained
      in this Agreement and the terms and conditions of the respective business
      forms of the Parties shall not form part of this Agreement.

      (d) Minimum Sales Amounts. The CMC will establish minimum sales amounts
          ---------------------
for ORCHID OEM Kits at least thirty (30) days prior to the end of each Contract
Year during the Term for the following Contact Year, which minimum sales shall

the CMC. If AFFYMETRIX does not achieve established minimum sales amounts for
two consecutive calendar quarters, then ORCHID, in its sole discretion, may
convert the exclusive license granted pursuant to section 3.1(a) to a
non-exclusive license with respect to that certain ORCHID OEM Kit. AFFYMETRIX
may terminate its exclusive license or convert said licenses to a non-exclusive
license at any time. In the event that the license is converted to a
non-exclusive license pursuant to this section, AFFYMETRIX's minimum sales
requirements for such ORCHID OEM Kit will no longer apply.

      (e) Marketing and Distribution of Custom Kits. Except as otherwise
          -----------------------------------------
described in this Agreement, ORCHID shall be solely responsible for
manufacturing, marketing and distributing Custom Kits to customers throughout

within 5 days of receipt of such order provide to AFFYMETRIX all Custom Kit
Information related to such customer's purchase (including, but not limited to
projected delivery dates) to enable AFFYMETRIX to coordinate sale of applicable
AFFYMETRIX products to such customer. At such time, ORCHID shall provide
AFFYMETRIX with the complete written specifications of such Custom Kit, subject
in each such case to any confidentiality obligation ORCHID may have to any Third
Party (and provided that ORCHID shall use commercially reasonable efforts to
minimize such obligations), which information AFFYMETRIX may use to determine
appropriate instrumentation and to promote the sale of other AFFYMETRIX
products. To the extent that such information is Confidential Information of
ORCHID, AFFYMETRIX shall not disclose such information to any third party. In
addition, to assist AFFYMETRIX with its marketing efforts with respect to the
Custom Kits, ORCHID shall on a regular basis (at least once each calendar
quarter) provide AFFYMETRIX with current marketing and sales information

mechanics of providing maintenance and support for the products marketed and
distributed pursuant to this Agreement. However, AFFYMETRIX shall be generally
responsible for front-line customer support for all Products except the Custom
Kits, and ORCHID shall provide backline support, as and when requested by
AFFYMETRIX, for ORCHID OEM Kits. Specifically, ORCHID shall provide such support
directly to one or more designated support managers of AFFYMETRIX. With respect
to ORCHID OEM Kits, ORCHID shall provide support and maintenance services to
AFFYMETRIX as further specified by and consistent with the level of support
provided by AFFYMETRIX with respect to AFFYMETRIX instruments, and there shall
be no fee to ORCHID (other than the transfer price for the kits) for rendering
such support.

catalogs and other promotional materials), distribute and support the Custom
Kits (including installation, training, and agrees to provide reasonable support
for customers and AFFYMETRIX as reasonably requested by AFFYMETRIX), and shall
use commercially reasonable efforts to meet market demands for Custom Kits, and
to provide support for Custom Kits. However, AFFYMETRIX shall provide backline
support, as and when requested by ORCHID for AFFYMETRIX instruments and tag
arrays used by purchasers of Custom Kits. Specifically, AFFYMETRIX shall provide
such support directly to one or more designated support managers of ORCHID
consistent with the level of support provided by AFFYMETRIX with respect to
AFFYMETRIX Approved instruments and Tag Arrays, and there shall be no fee to
AFFYMETRIX for rendering such support. If at any time during the Term of this
Agreement, ORCHID elects to discontinue or transfer to a third party the
manufacture, sale or marketing any Custom Kit pursuant to this Agreement, ORCHID
shall notify AFFYMETRIX in writing, and AFFYMETRIX shall have 30 days to advise
ORCHID of its interest in manufacturing and/or distributing and selling such
Custom Kit during the Term. If AFFYMETRIX advises ORCHID of its interest, then
the Parties shall negotiate for 60 days in good faith to determine the
appropriate royalty or other fee (if any) that AFFYMETRIX shall pay to ORCHID.
If the parties cannot reach agreement within such period, then ORCHID may
discontinue manufacture and sale of such Custom Kit or transfer such kit to a
third party, provided that if ORCHID elects to transfer such kit to a third
party, the royalty or other fees paid by such third party must be higher than
the royalty or other fees last offered by AFFYMETRIX.

      (c) Reports. Each Party shall provide the other Party with such
          -------
information about their respective products and services as is reasonably
necessary to support the development and marketing of technical support
materials, and the training of technical support personnel for ORCHID OEM Kits.
(d) Rights to Sell Kits. ORCHID represents, warrants and covenants that the
restrictions set forth in the Security Agreement dated September 11, 1998 by and
among ORCHID and GeneScreen, Inc. ("GeneScreen Security Interest") are the only
restrictions imposed on ORCHID with respect to the manufacture, use,
distribution, modification or sale by AFFYMETRIX or use by AFFYMETRIX's end
users of ORCHID OEM Kits or the Custom Kits. In the event that the obligations
of ORCHID with respect to any such restriction is reduced, ORCHID shall promptly
notify AFFYMETRIX, and promptly provide AFFYMETRIX with any information
requested by AFFYMETRIX with respect to such restriction. If Orchid believes
that it needs to access third party intellectual property in order to avoid
encumbering its ability to sell Orchid OEM Kits to AFFYMETRIX, it will discuss
this with the CMC. If no CMC agreement is reached within 30 days, then Orchid
can enter into a license at its discretion, provided that Affymetrix's rights
under this agreement will not be limited by such license.

      (d) Rights to Sell Kits. ORCHID represents, warrants and covenants that
          -------------------
the restrictions set forth in the [*] are the only restrictions imposed on
ORCHID with respect to the manufacture, use, distribution, modification or sale
by AFFYMETRIX or use by AFFYMETRIX's end users of ORCHID OEM Kits or the Custom
Kits. In the event that the obligations of ORCHID with respect to any such
restriction is reduced, ORCHID shall promptly notify AFFYMETRIX, and promptly
provide AFFYMETRIX with any information requested by AFFYMETRIX with respect to
such restriction. If Orchid believes that it needs to access third party
intellectual property in order to avoid encumbering its ability to sell Orchid
OEM Kits to AFFYMETRIX, it will discuss this with the CMC. If no CMC agreement
is reached within 30 days, then Orchid can enter into a license at its
discretion, provided that Affymetrix's rights under this agreement will not be
limited by such license.

      (e) Covenant Not to Sue. Except for the manufacture of Orchid OEM Kits by
          -------------------
AFFYMETRIX in violation of this Agreement, ORCHID agrees that it shall not
assert in any way ORCHID Licensed Technology against AFFYMETRIX, its
subsidiaries or affiliates, for the manufacture, use, import, offer for sale or
sale of AFFYMETRIX products. If ORCHID assigns ownership of any of its ORCHID
Licensed Technology to a third party not bound by this covenant not to sue
(whether directly or by operation of law), then such assignment shall be subject
ot this covenant not to sue.

      (b) Supply. ORCHID shall supply ORCHID OEM Kits to AFFYMETRIX in
          ------
accordance with the purchase orders submitted to ORCHID by AFFYMETRIX, including
the delivery schedules specified therein; provided, that ORCHID shall not be
required to fill any purchase orders from AFFYMETRIX requesting a delivery date
earlier than [*] after receipt of such orders by ORCHID. ORCHID will maintain
adequate production capacity to ensure delivery of ORCHID OEM Kits in accordance
with such purchase orders and shall ensure that ORCHID OEM Kits meet the
Specifications set by the CMC. ORCHID hereby grants AFFYMETRIX a, worldwide,
non-transferable, non-exclusive license under ORCHID Licensed Technology, to,
(1) develop Generic Kits and Standard Kits as authorized in Section 2.2(d), (2)
make, have made, and use (which use includes the right to modify) Orchid OEM
Kits and (3) distribute, market and sell such ORCHID OEM Kits ("OEM License")

AFFYMETRIX agrees to forbear from the use and exercise of the OEM License unless
and until ORCHID fails to fill any purchase order within [*] after receipt of
such order, ORCHID has otherwise breached this Agreement, or ORCHID sells
substantially all of ORCHID's business that relates to the subject matter of
this Agreement to a third party which Affymetrix believes in good faith
materially competes with Affymetrix, or which Affymetrix believes in good faith
could not or would not satisfy its obligation hereunder. If AFFYMETRIX' use and
exercise of the OEM License is caused by ORCHID'S failure to fill a purchase
order (and no other reason), AFFYMETRIX' forbearance shall be reinstated once
ORCHID demonstrates to the reasonable satisfaction of AFFYMETRIX (which shall
not be unreasonably withheld) that ORCHID is again able to fill purchase orders
within the time limits set forth in Section 4.1. During the time that AFFYMETRIX
is not forbearing from use and exercise of the OEM License, ORCHID shall provide
promptly (at no charge) to AFFYMETRIX or an approved third party designated by
AFFYMETRIX, all technical assistance and information as reasonably required to
enable AFFYMETRIX, or said third party, to supply OEM Kits as set forth in this
Section. During the time that AFFYMETRIX is not forbearing from use and exercise

ORCHID OEM Kits which fall under the new OEM License (which royalty shall be
subject to reduction in the manner and scope described in Section 2.2(d)) unless
the Parties agree in writing to a lower rate; provided, further, however, that
if AFFYMETRIX'S use and exercise of the OEM License is caused by ORCHID'S
failure to fill a purchase order (and no other reason), and ORCHID resumes
manufacture of ORCHID OEM Kits under this Section, then the transfer price paid
by AFFYMETRIX for such ORCHID OEM Kits shall be reduced by [*] until such time
as AFFYMETRIX has recovered an amount equal to any costs and expenses incurred
to exercise the OEM License (including any royalties paid under this Section.)

      (c) Packaging; Delivery. The ORCHID OEM Kits delivered hereunder shall be

thirty (30) days following the date of such invoice. Any undisputed amounts not
paid when due under this Agreement shall be subject to a late fee equal to [*]
of the outstanding amount or the maximum rate permitted by law, whichever is
less.

          -----
practices, each Party shall maintain, for a period of [*] following
the end of the Contract Year, complete and accurate books and records fully
adequate to confirm the accuracy of the royalties, fees or commissions paid and
payable under this Agreement. Each of the Parties shall have the right, [*] per
calendar year, or more frequently if an examination determines that there has
been an underpayment of more than [*], during regular business hours and upon
[*] prior written notice, to have its independent auditors make such
examination as necessary to

rejected by AFFYMETRIX, ORCHID shall use diligent efforts, at AFFYMETRIX's
request, to provide replacement ORCHID OEM Kits to AFFYMETRIX or to correct any
defects in such shipment as may be reasonably requested by AFFYMETRIX. Unless
ORCHID requests the return of a rejected shipment within [*] of receipt of
AFFYMETRIX's notice of rejection, AFFYMETRIX shall destroy such shipment
promptly and provide ORCHID with a certification of such destruction. To ensure
that the Parties can supply all third party requirements with accepted ORCHID
OEM Kits, ORCHID shall at all times maintain an inventory of ORCHID OEM Kits

other fees shall be due or owing ORCHID in respect of such TAG Improvement; and
(b) if AFFYMETRIX creates, invents or otherwise develops any improvements to GBA

expressly set forth in this Agreement.

6.    CONFIDENTIAL INFORMATION
      ------------------------

      6.1 CONFIDENTIALITY. ORCHID and AFFYMETRIX each recognize that the other
          ---------------
party's Confidential Information constitutes highly valuable and proprietary
confidential information. ORCHID and AFFYMETRIX each agree that during the Term
of the Collaboration and for [*] thereafter, it will keep confidential, and will
cause its employees, consultants, Affiliates and licensees and sublicensees to
keep confidential, and shall not transfer to any Third Party, any Confidential
Information of the other Party that is disclosed or transferred to it, or to any
of its employees, consultants, Affiliates and licensees and sublicensees,
pursuant to or in connection with this Agreement, except to the extent that
disclosure, or transfer, is reasonably required in accordance with the
performance of this Agreement. Each Receiving Party's nondisclosure obligation
shall not apply to information that is (i) known to the Receiving Party at the
time of disclosure thereof (as shown by written documentation); (ii) at the time
of disclosure, or thereafter, is generally publicly available without the fault
of the Receiving Party; (iii) subsequently disclosed to the Receiving Party, its
employees, or other duly designated representatives, by any Third Party not
under a secrecy obligation to the Disclosing Party; (iv) independently developed
by the Receiving Party without reference to Confidential Information of the
Disclosing Party; (v) required, by law, regulation or action of any governmental
agency or authority, to be disclosed; or (vi) disclosed by the Receiving Party
with the prior written consent of the Disclosing Party.

      6.2 NON-DISCLOSURE. ORCHID and AFFYMETRIX each agree that any disclosure
          --------------
of the Confidential Information to any of its officers, employees, consultants
or agents or of any of its Affiliates and licensees and sublicensees shall be
made only if and to the extent necessary to carry out its rights and
responsibilities under this Agreement, shall be limited to the maximum extent
possible consistent with such rights and responsibilities and shall only be made
to persons who are bound by written confidentiality obligations to maintain the
confidentiality thereof and not to use such Confidential Information except as
expressly permitted by this Agreement. Each Party shall take such action, and
shall cause its Affiliates and licensees and sublicensees to take

                                                                  Execution Copy


such action, to preserve the confidentiality of each other's Confidential
Information as it would customarily take to preserve the confidentiality of its
own Confidential Information, and in no event, less than reasonable care.

      6.3 EMPLOYEES AND CONSULTANTS. ORCHID and AFFYMETRIX each represent that
          -------------------------
all of its employees and the employees of its Affiliates, and any consultants to
such party or its Affiliates, participating in the Collaboration's activities
who shall have access to Confidential Information of the other Party are bound
by written obligations to maintain such information in confidence and not to use
such information except as expressly permitted herein. Each Party agrees to
enforce confidentiality obligations to which its employees and consultants (and
those of its Affiliates) are obligated.

      6.4 PUBLICITY. Neither Party shall disclose the existence or the terms or
          ---------
conditions of this Agreement without the express prior written consent of the
other Party, and then only pursuant to the terms authorized by such other Party;
provided, however, that either Party may make such a disclosure to the extent
required by law or by the requirements of any nationally recognized securities
exchange, quotation system or over-the-counter market on which such Party has
its securities listed or traded. The Parties, upon the execution of this
Agreement, will agree to a news release with respect to the Collaboration for
publication in general circulation and industry periodicals. Once any written
statement is approved for disclosure by both Parties, either Party may make
subsequent public disclosure of the contents of such statement without the
further approval of the other Party.

7.    TERM AND TERMINATION
      --------------------

      7.1 TERM. Unless earlier terminated in accordance with the provisions of
          ----

required) to terminate this Agreement by written notice to the other Party in
the event that the other Party shall be in default of any of its obligations

operations; or (b) the other Party shall seek protection under any bankruptcy,
receivership, trust deed, creditors arrangement, composition or comparable
proceeding, or if any such proceeding is instituted against the other. All
rights and licenses granted under this Agreement are deemed to be, for purposes
of 365(n) of the United States Bankruptcy Code, license or rights to
"intellectual property" as defined by Section 101(56) of the United States
Bankruptcy Code and the parties will retain any may fully exercise all of their
rights and licenses under this Agreement, including the right to make or have
made, sell or have sold Products. The parties agree to relief from automatic
stay provisions under Section 362 of the Bankruptcy Code.

      7.4 EFFECT OF TERMINATION. Upon any termination or expiration of this
          ---------------------
Agreement, neither Party shall be relieved of any obligations incurred prior to
such termination. Notwithstanding any termination or expiration of this
Agreement, the rights and obligations of the Parties under Sections 4.1(e), 5,
6, 7, 8, 10 and 11 shall survive and continue to be enforceable. Upon any
termination of this Agreement, each Party shall promptly return to the other
Party all written Confidential Information, and all copies thereof, of the
other, except for one copy thereof that may be retained by a Party's legal
department for archival purposes or to exercise rights described above that
survive termination. Neither Party shall incur any liability or compensation
obligation whatsoever for any damage (including, without limitation, damage to
or loss of goodwill or investment), loss or expenses of any kind suffered or
incurred by the other (or for any compensation to the other) arising from or
incident to any termination of this Agreement by such Party that complies with
the terms of the Agreement whether or not such Party is aware of any such
damage, loss or expenses.

8.    INDEMNIFICATION AND INSURANCE
      -----------------------------

      8.1 ORCHID INDEMNITY. ORCHID agrees to defend AFFYMETRIX and its
          ----------------
Affiliates, their agents, directors, officers and employees ("AFFYMETRIX
Indemnitees"), at ORCHID's cost and expense, and will indemnify and hold
harmless AFFYMETRIX Indemnitees from and against any and all losses, liability,
damages, costs and expenses (including, but not limited to attorneys' fees and
expenses (collectively, "Claims") (except in cases where such Claims result from
a material breach of this Agreement or willful misconduct on the part of
AFFYMETRIX) arising from or relating to (1) any alleged infringement by
AFFYMETRIX [or its customers] of any Third Party intellectual property or
proprietary rights solely attributable to AFFYMETRIX's sale or customer's use as
intended, of all or any part of the ORCHID OEM Kits or Custom Kits (including
but not limited to Reagents) or (2) any recall of any ORCHID OEM Kits or (3)
ORCHID's breach of any representation or warranty of ORCHID set forth in this
Agreement or (4) any other materials supplied by ORCHID hereunder, or (5) death
or any injury to any person or damage to property as a result of the possession
or use of any ORCHID OEM Kits or Custom Kits.

      8.2 AFFYMETRIX INDEMNITY. Subject to the obligations of ORCHID set forth
          --------------------
in 8.1 above, AFFYMETRIX agrees to defend ORCHID and its Affiliates, their
agents, directors, officers and employees ("ORCHID Indemnitees"), at
AFFYMETRIX's cost and expense, and will indemnify and hold harmless ORCHID
Indemnitees from and against any and all Claims (except in cases where such
Claims result from a material breach of this Agreement or willful misconduct on
the part of ORCHID) arising from or relating to (1) any alleged infringement
attributable to ORCHID's sales to AFFYMETRIX of ORCHID OEM Kits or sales of
Custom Kits (provided, however, that such indemnity shall be limited to Claims
of infringement caused by Approved Instruments and TAG Arrays except to the
extent that such Claim arises from or relates to any combination of the ORCHID
OEM Kits or Custom Kits with any Approved Instrument or the TAG Array) or (2)
any recall of any an Affymetrix instrument or Commercial Probe Arrays delivered
to a customer in conjunction with ORCHID OEM Kits, or (3) AFFYMETRIX's breach of
any representation or warranty of AFFYMETRIX set forth in this Agreement or (4)
any other materials supplied by AFFYMETRIX hereunder (provided, however, that
such indemnity shall not include any Claims of infringement arising from or
relating to any combination of the ORCHID OEM Kits or Custom Kits with any
Approved Instrument or the TAG Array except to the extent that such Claim would
have existed in the absence of such combination), or (5) death or any injury to
any person or damage to property as a result of the possession or use of any
Instrument or Commercial Probe Array delivered to a customer in conjunction with
ORCHID OEM Kits.

      8.3 PROCEDURE. In the event of any such claim, the Party seeking indemnity
          ---------
shall promptly notify the indemnifying Party in writing of the claim and the
indemnifying Party shall have the right, to manage and control, at its sole
expense, the defense of the claim and the settlement thereof. The indemnified
Party shall cooperate with the indemnifying Party and may, at its option and
expense, be represented in any such action or proceeding. The indemnifying Party
shall not be liable for any settlements, litigation costs or expenses incurred
by the indemnified Party without the indemnifying Party's written authorization.
Notwithstanding the foregoing, unless and until ORCHID achieves annual revenues
of [*] million, AFFYMETRIX shall have the right at their expense, but not the
obligation to defend the AFFYMETRIX Indemnitees against any claim of
infringement without tendering defense thereof to ORCHID; provided, however,
that ORCHID may participate in such defense at its own expense

      8.4 INSURANCE. Each Party agrees to use its best efforts to procure and,
          ---------
at all times during the term of this Agreement, to maintain in full force and
effect general liability insurance coverage of at least $1,000,000 per
occurrence and at least $5,000,000 aggregate (with a deductible of no more than
$50,000 aggregate per year and which policy names the other Party as a named
insured). Each Party, upon request of the other Party, will supply such other
Party with appropriate certificates of insurance evidencing the foregoing
insurance.

9.    REPRESENTATIONS AND WARRANTIES
      ------------------------------

      9.1 Each of the Parties represents and warrants to the other Party as
follows:

                                    Page 14
<PAGE>

                                                                  Execution Copy


      9.2 The execution and delivery of this Agreement and the performance of
the transactions contemplated hereby and thereby have been duly authorized by
all appropriate corporate action, and the Party has all requisite power and
authority to enter into this Agreement and to perform its obligations hereunder
and thereunder, and each representation of this Agreement constitutes a valid
and binding obligation of each Party, enforceable against each Party in
accordance with its terms.

      9.3 The performance by the Party of any of the terms and conditions of
this Agreement on its part to be performed does not and will not constitute a
breach of any other agreement or understanding, whether written or oral, to
which it or any of its affiliates is a party.

      9.4 The Party has the right to convey all technical information and
technology conveyed hereunder and that the information and technology so
conveyed does not violate the trade secret rights or copyrights of a third party
and to its knowledge, does not violate the patent or trademark rights of a third
party.

      9.5 The Party has used reasonable commercial efforts to ensure the quality
of the materials and data provided hereunder.

10.   DISPUTE RESOLUTION
      ------------------

      10.1 SENIOR OFFICIALS. In the event of any controversy or claim relating
           ----------------
to, arising out of or in any way connected to any provision of this Agreement
("Dispute"), either Party may, by notice to the other Party, have such dispute
referred to their respective senior officials designated below or their
successors, for attempted resolution by good faith negotiations within thirty
(30) days after such notice is received. Said designated employees are as
follows:

       For ORCHID:      CEO

       For AFFYMETRIX:  CEO

      10.2 MEDIATION. In the event the designated senior officials are not able
           ---------
to resolve any such dispute within the thirty (30) day period, either Party may
invoke the provisions of this Section 11.2 by initiating mediation of the
Dispute under the then correct Center for Public Resources Procedure for
Mediation of Business Disputes. Once mediation is initiated by one Party, the
other Party shall participate in and conduct the mediation procedures in good
faith. If a negotiator intends to be accompanied at a telephone conference or a
meeting by an attorney, the negotiator for the other Party shall be given at
least three (3) days notice of such intention, and may also be accompanied by an
attorney. All negotiations pursuant to this clause are confidential and shall be
treated as compromise and settlement negotiations for the purposes of the
Federal Rules of Evidence and any state rules of evidence. All applicable
statutes of limitations and defenses based on the passage of time shall be
tolled while the negotiation and mediation procedures set forth in this Section
10.2 are pending. The Parties will take such action, if any, as may be
reasonably required to effectuate such tolling.

      10.3 ARBITRATION. Any Dispute that is not resolved pursuant to Section
           -----------
10.2 shall be finally resolved by final and binding arbitration. Whenever a
Party shall decide to institute arbitration proceedings, it shall give written
notice to that effect to the other Party. The Party giving such notice shall
refrain from instituting the arbitration proceedings for a period of ten (10)
days following such notice to allow the Parties to attempt to resolve the
dispute between themselves. If the Parties are still unable to resolve the
dispute, the Party giving notice may institute the arbitration proceeding under
the rules of the American Arbitration Association ("AAA Rules"). Arbitration
shall exclusively and solely be held in San Francisco, California. The
arbitration shall be conducted before a single arbitrator mutually chosen by the
Parties, but if the parties have not agreed upon a single arbitrator within
fifteen (15) days after notice of the institution of the arbitration proceeding,
then the arbitration will be conducted by a panel of three arbitrators. In such
case, each Party shall within thirty (30) days after notice of the institution
of the arbitration proceedings appoint one arbitrator. The presiding arbitrator
shall then be appointed in accordance with AAA Rules. No arbitrator (nor the
panel of arbitrators) shall have the power to award punitive

<PAGE>

                                                                  Execution Copy


damages or any award of multiple damages under this Agreement and such awards
are expressly prohibited. Decisions of the arbitrator(s) shall be final and
binding on the Parties.

      10.4 Notwithstanding the foregoing, if within ten (10) days of the first
occasion when the Parties' representatives meet with the arbitrator(s) either
Party gives notice by written designation of any matter relating solely to the
validity or scope of any patent as being subject to the Patent Exception
referred to above, then the matter so designated shall be set aside by the
arbitrator(s) and shall not be decided by them, provided that the matter so
designated constitutes a matter of which a United States District Court would
have jurisdiction pursuant to 28 U.S.C. (S) 1338(a), whether by way of action
for declaratory judgment or otherwise, and provided further that such matter is
submitted by the designating Party for decision by such court upon a complaint
filed within thirty (30) days of such designation, to be decided as such court
may determine. The sole jurisdiction and venue for actions related to the
subject matter hereof shall be the California state and U.S. federal courts
located in San Francisco, California. In such case, the nondesignating Party may
elect (no later than the date on which it files its answer to the complaint in
the District Court) to refer the entire matter in controversy to such court, but
if such Party does not make such election the arbitrator(s) shall proceed to
decide the remaining matter before them to the extent feasible and shall take
such other action in such regard as they deem appropriate. Judgment on the award
of the arbitrator(s) may be entered in any court having jurisdiction thereof.

      10.5 Except to the extent entry of judgment and any subsequent enforcement
may require disclosure, all matters relating to the arbitration, including the
award, shall be held in confidence by the Parties.

11.   MISCELLANEOUS.
      -------------

      11.1 Except as otherwise provided in this Agreement, neither this
Agreement nor any of the rights or obligations hereunder may be assigned by

authority; epidemic; destruction of production facilities; riots; insurrection;
inability to procure or use materials, labor, equipment, transportation or
energy; or any other cause beyond the reasonable control of the Party invoking
this Section if such Party shall have used its best efforts to avoid such
occurrence, such Party shall give notice to the other Party in writing promptly,
and thereupon the affected Party's performance shall be excused and the time for
performance shall be extended for the period of delay or inability to perform
due to such occurrence.

      11.5 The waiver by either Party of a breach or a default of any provision
of this Agreement by the other Party shall not be construed as a waiver of any
succeeding breach of the same or any other provision, nor shall any delay or
concession on the part of either Party to exercise or avail itself of any right,
power or privilege that it has or may have hereunder operate as a waiver of any
right, power or privilege by such Party.

      11.6 Any notice or other communication in connection with this Agreement
must be in writing and if by mail, by certified mail, return receipt requested,
and shall be effective when delivered to the addressee at the address listed
below or such other address as the addressee shall have specified in a notice

represented by the total shares of Series A Convertible Preferred Stock and
Common Stock issued to Sarnoff as set forth in Sections 3.1(a) and (b) and
Section 3.2 (the "Issued Shares"), and regardless of whether or not Sarnoff may
have sold all or a portion of such Issued Shares, drops below 20% of all shares
of capital stock of Orchid then outstanding (calculated by assuming conversion
of all outstanding convertible securities and exercise of all outstanding
warrants) (such January 1 being referred to herein as the "Royalty Commencement
Date"), in consideration of the exclusive licenses granted pursuant to Section
2.1.1 and the non-

                                       13

exclusive licenses granted pursuant to Section 2.1.2 Orchid shall make payments
to Sarnoff of royalties as follows:

     (a) One and one-half percent (1.5%) of Net Sales by Orchid and its
Affiliates of Products and Services whose discovery, development, testing,
manufacture, use, sale, importation, lease or offer for sale would, but for the
licenses granted hereunder, infringe a Valid Claim of a Patent Right included in
the Licensed Technology which is not a Joint Patent Right and which is
exclusively licensed hereunder, or whose discovery, development, testing,
manufacture, use, sale, importation, lease or offer for sale directly employs or
embodies proprietary Licensed Technology which is not a Joint Invention and
which is exclusively licensed hereunder, provided however that for Products
which incorporate Licensed Technology and either Developed Technology (as
defined in the SB Agreement), or technology developed under the Dynal Agreements
or Services provided using such Products, the royalty rate shall be one percent
(1%) of Net Sales;

     (b) Three fourths of one percent (.75%) of Net Sales by Orchid and its
Affiliates of Products and Services whose discovery, development, testing,
manufacture, use, sale, importation, lease or offer for sale would, but for the
licenses granted hereunder, infringe a Valid Claim of a Joint Patent Right, but
not any other Patent Right, which is included in the Licensed Technology and
which is exclusively licensed hereunder, or whose discovery, development,
testing, manufacture, use, sale, importation, lease or offer for sale directly
employs or embodies only such Licensed Technology which is a Joint Invention and
which is exclusively licensed hereunder;

     (c) for (i) sales by any licensees or sublicensees of Orchid of any such
Products or Services as specified in Section 3.4(a) or (b), and (ii) payments
received by Orchid under a sublicense of exclusive Licensed Technology, Orchid
shall pay Sarnoff ten percent (10%) of any non-refundable amounts received by
Orchid from such licensees or sublicensees, including but not limited to
advanced and minimum royalties, up front and milestone project and licensing
fees (excluding equity investments by licensees or sublicensees and excluding
fees paid to Orchid in any form which are required to be used for research or
other services to be performed by Orchid).

     3.5    Royalties under Non-exclusive License.  In consideration of the non-
exclusive licenses granted pursuant to Section 2.1.2, except for Products which
incorporate no Licensed Technology other than Developed Technology (as defined
in the SB Agreement), and/or technology developed under the Dynal Agreements or
Services provided using such Products which incorporate no Licensed Technology
other than Developed Technology (as defined in the SB Agreement), and/or
technology developed under the Dynal Agreements, Orchid shall make payments to
Sarnoff of royalties without regard to Sarnoff's ownership of Issued Shares as
follows:

     (a) One and one-half percent (1.5%) of Net Sales by Orchid and its
Affiliates of Products and Services whose discovery, development, testing,
manufacture, use, sale, importation, lease or offer for sale would, but for the
licenses granted hereunder, infringe a Valid Claim of a Patent Right included in
the Licensed Technology which is not a Joint Patent Right and which is non-
exclusively licensed hereunder, or whose discovery, development, testing,

                                       14
<PAGE>
manufacture, use, sale, importation, lease or offer for sale directly employs
or embodies proprietary Licensed Technology which is not a Joint Invention and
which is non-exclusively licensed hereunder, provided however that for Products
which incorporate Licensed Technology and either Developed Technology (as
defined in the SB Agreement), or technology developed under the Dynal Agreements
or Services provided using such Products, the royalty rate shall be one percent
(1%) of Net Sales; and

     (b) Three fourths of one percent (.75%) of Net Sales by Orchid and its
Affiliates of Products and Services whose discovery, development, testing,
manufacture, use, sale, importation, lease or offer for sale would, but for the
licenses granted hereunder, infringe a Valid Claim of a Joint Patent Right, but
not any other Patent Right, which is included in the Licensed Technology and
which is non-exclusively licensed hereunder, or whose discovery, development,
testing, manufacture, use, sale, importation, lease or offer for sale directly
employs or embodies only such Licensed Technology which is a Joint Invention and
which is non-exclusively licensed hereunder; and

     (c) for (i) sales by any licensees or sublicensees of Orchid of any such
Products or Services as specified in Section 3.5(a) or (b) and (ii) payments
received by Orchid under a sublicense of non-exclusive Licensed Technology,
Orchid shall pay Sarnoff ten percent (10%) of any non-refundable amounts
received by Orchid from such licensees or sublicensees, including but not
limited to advanced and minimum royalties, up front and milestone project and
licensing fees (excluding equity investments by licensees or sublicensees and
excluding fees paid to Orchid in any form which are required to be used for
research or other services to be performed by Orchid).

     (d) In addition, Orchid shall pay Sarnoff for each Option Field for which
Orchid has a non-exclusive license under Section 2.1.2 on the relevant date the
following minimum royalties for each Option Field: (i) on January 1, 2002,
$50,000 per Option Field, (ii) on January 1, 2003, $100,000 per Option Field,
and (iii) on January 1, 2004 and each subsequent January 1, $200,000 per Option
Field per year. These minimum royalties shall be a credit for royalties to be
paid under Section 3.5(a) on an Option Field-by-Option Field basis for the
calendar year for which the minimum royalty payment is made. For Option Fields
which are exclusively licensed to Orchid, the provisions of Section 3.4 shall
govern and no royalties or fees shall be due pursuant to this Section 3.5. For
Option Fields where Orchid notifies Sarnoff, at least thirty (30) days prior to
the minimum royalty due date, that Orchid does not wish to maintain its non-
exclusive license, no minimum royalty payment shall be due and Orchid shall no
longer have a non-exclusive license for such Option Field.

     3.6  Royalty Reductions. In the event that royalties and fees paid to
Sarnoff pursuant to Section 3.4 or 3.5 shall become a significant factor in the
return realized by Orchid such as to substantially diminish its capability to
respond to competitive pressures in the market, the parties shall mutually agree
on a reasonable reduction in the royalties and fees payable under this Agreement
with respect to the affected Products and Services.  Factors to be considered in
agreeing on the royalty reduction shall include but not be limited to the profit
margin on such


                                       15
<PAGE>

Products and Services and on analogous and/or competitive Products and Services
and prices and expenditures therefor.

     3.7  Royalty Term.  Royalties hereunder shall be payable only until the
expiration of the last to expire of the Patent Rights covering a particular
Product or Service.  Thereafter, Orchid shall have a fully paid up, perpetual
non-exclusive license to all Licensed Technology for such Product or Service.

     3.8  Royalty Reporting Provisions.

     (a)  Orchid agrees to submit to Sarnoff within sixty (60) days after the
calendar quarters ending March 31, June 30, September 30, and December 31 of
each year in which royalties are due hereunder, reports setting forth for the
preceding three (3) month period at least the following information for Orchid,
its Affiliates and sublicensees:

          i)    total billings for Products sold;

          ii)   total billings for all Services provided or sold;

          iii)  deductions applicable to determine the Net Sales thereof;

          iv)   the amount of royalty due thereon; and with each such royalty
                report to pay the amount of royalty due.

     (b)  All such reports shall be maintained in confidence by Sarnoff, except
as required by law.

     (c)  All payments due hereunder shall be payable in United States dollars.
Conversion of foreign currency to U.S. dollars shall be made at the conversion
rate existing in the United States (as reported in The Wall Street Journal) on
the last working day of each royalty period.

     (d)  Any tax paid or required to be withheld by Orchid on account of
royalties payable to Sarnoff under this Agreement shall be deducted from the
amount of royalties otherwise due. Orchid shall secure and send to Sarnoff proof
of any such taxes withheld and paid by Orchid for the benefit of Sarnoff.

     (e)  If governmental regulations prevent remittances from a foreign country
with respect to sales made or fees received in that country, the obligation of
Orchid to pay royalties on such sales and/of fees shall be suspended until such
remittances are permitted. Sarnoff shall have the right, upon giving written
notice to Orchid, to receive payment in such country in local currency.

     3.9  Royalties to Third Parties. In the event Orchid becomes liable to pay
royalties or other amounts to any third party as a result of the sale of any
product or the delivery of any services by Sarnoff or any Affiliate of Sarnoff
under Section 6 of the SB Agreement or otherwise, then Sarnoff shall be liable
for all such royalties or other amounts and shall, at Orchid's option, either
pay such amounts directly to the third party or shall reimburse Orchid for such
royalties or other amounts within thirty (30) days after receipt of an invoice
from Orchid.

                                       16
<PAGE>

     3.10  Royalty Audits. Orchid shall keep complete, true and accurate books
of account and other appropriate records for the purpose of showing the amount
payable to Sarnoff by way of royalty and of cumulative Net Sales and otherwise
showing Orchid's compliance with Section 3 of this Agreement. Said books and the
supporting data and other documentation, including technical information
relevant to the determination of Orchid's obligations hereunder, shall be kept
at Orchid's principal office and maintained for three (3) years following the
end of the calendar year to which they pertain.  Such records, solely to the
extent relevant to the determination of Orchid's obligations under Section 3 of
this Agreement shall be open, upon reasonable notice and at reasonable times
during normal business hours, to the inspection by independent, certified public
accounts (to be selected solely by Sarnoff and reasonably acceptable to Orchid)
at Sarnoff's expense.  However, if a discrepancy of more than five percent (5%)
of royalties due Sarnoff is discovered by the inspection, then the cost of the
inspection shall be performed at Orchid's expense.

                                       18
<PAGE>

     5.2. Patents.

          5.2.1.  Patent Prosecution.

          Sarnoff shall, by qualified independent patent counsel, prepare, file,
prosecute and maintain patent applications, and maintain and enforce Patent
Rights included in the Licensed Technology in the countries of United States,
Canada, Australia, Europe Patent Office (designating Austria, France, Germany,
Spain, Ireland, Italy, Netherlands, Sweden, Switzerland, United Kingdom), Japan,
and Korea and such other countries as mutually agreed between Orchid and Sarnoff
and shall have all rights to otherwise deal in and to enforce rights associated
with Licensed Technology except as otherwise provided in Section 6.2. Sarnoff
shall provide Orchid with copies of all proposed patent and other applications
and filings and communications and give Orchid the reasonable opportunity to
comment thereon and Sarnoff will consider in good faith any comments provided to
Sarnoff by Orchid prior to filing. Sarnoff agrees to deliver to Orchid copies of
any communications with the applicable patent office, including without
limitation, all office actions and responses, each patent application and
filing, and each registration that issues thereon.

          5.2.2.  Cooperation. Orchid agrees to cause each of its employees and
agents to take all actions and to execute, acknowledge and deliver all
instruments or agreements reasonably requested by Sarnoff, and necessary for the
perfection, maintenance, enforcement or defense of Patent Rights as set forth

          5.2.3. Financing of Costs. Orchid agrees to pay to Sarnoff fifty
percent (50%) of Sarnoff's reasonable out of pocket costs incurred in the
preparation, filing, translation, prosecution, issuance and maintenance of any
such patent applications or patents relating to Licensed Technology except for
Licensed Technology under Section 1.17(f) prepared or filed after the Effective
Date and fifty percent (50%) of the maintenance costs for such Patent Rights
incurred by Sarnoff after the Effective Date, provided that such prosecution is
conducted as set forth in Section 5.2.1 above. If Orchid declines in writing to
pay to Sarnoff its fifty percent (50%) share of the costs of a particular Patent
Right in a particular country, Orchid's license to such Patent Right in such
particular country shall be terminated as of the Due Date. If Orchid fails to
pay to Sarnoff within thirty (30) days from date of receipt of invoice (the "Due
Date"), and such failure continues for a period of 30 days after written notice
to Orchid by Sarnoff of such failure to pay, Orchid's license to such Patent
Right in such particular country shall be terminated as of the Due Date.

          5.2.4.  Election to Discontinue Prosecution.  Sarnoff may, with
respect to the Patent Rights, at any time, in its sole discretion decide that it
desires to discontinue its responsibility for the prosecution or maintenance of
a particular patent application or patent in one or more countries of Patent
Rights which are Licensed Technology under Section 1.17(a), (b), (c), (d), (e)
and (g).  In such event, Sarnoff shall notify Orchid promptly in writing of its
intention to discontinue responsibility for the prosecution or maintenance for
such patent application or patent, and, in any event, shall give such notice at
least sixty (60) days prior to the effective date of such proposed
discontinuance in order to permit Orchid to determine whether it wishes to
assume the responsibility therefor.  Orchid shall have the right and option, but
not the obligation, to assume responsibility for prosecution and maintenance of
such patent or patent

                                       19
<PAGE>

application which Sarnoff desires to discontinue. Orchid shall inform Sarnoff in
writing of its decision to assume responsibility for prosecution and maintenance
of such patent or patent application and Sarnoff shall execute and deliver such
documents and take such actions as are reasonably necessary or appropriate to
effect such assumption and transfer of responsibility in a timely and efficient
manner. In the event Orchid exercises such right, such patent or patent
application shall be assigned to Orchid and removed from operation of this
Agreement; provided that, Sarnoff shall have a royalty free, non-exclusive,
worldwide, right and license under such Licensed Technology with the right to
sublicense, to develop, have developed, make, have made, use, have used, import,
have imported, offer for sale, sell have sold or lease products and practice
processes outside the Orchid Field and the Option Fields so long as the Options
remain in effect and further provided that upon termination of this Agreement,
such patents and patent applications shall be assigned to Sarnoff. However, if
Sarnoff elects to use or sublicense a particular patent in a particular country
assigned by Sarnoff to Orchid under this Section 5.2.4, then Sarnoff shall pay
to Orchid one half of the out of pocket costs expended by Orchid in obtaining
and maintaining the particular patent in the particular country.

     5.3.  Confidential Information.  Any Party receiving or possessing
Confidential Information of the other Party shall use commercially reasonable
efforts to: (i) maintain the confidential and proprietary status of such
Confidential Information; (ii) keep such Confidential Information and each part
thereof within its possession or under its control sufficient to prevent any
activity with respect to the Confidential Information that is not specifically
authorized by this Agreement; (iii) prevent the disclosure of any Confidential
Information to any other Person; and (iv) ensure that such Confidential
Information is used only for those purposes specifically authorized herein;
provided, however, that such restriction shall not apply to any Confidential
Information which is (a) independently developed by the receiving Party without
reference to Confidential Information of the disclosing Party, (b) in the public
domain at the time of its receipt or thereafter becomes part of the public
domain through no fault of the receiving Party, (c) received by the receiving
Party without an obligation of confidentiality from a third party having the
right to disclose such information, (d) released from the restrictions of this
Section 5.3 by the express written consent of the disclosing Party, (e)
disclosed to any actual or prospective permitted assignee, Partner, investor,
licensee, sublicensee or subcontractor of either Sarnoff or Orchid (if such
actual or prospective assignee, Partner, investor, licensee, sublicense or
subcontractor is subject to the provisions of this Section 5.3 or comparable
provisions of other documents), or (f) required by law, statute, rule or court
order to be disclosed (the disclosing party shall, however, use commercially
reasonable efforts to obtain confidential treatment of any such disclosure and
shall notify the other party in writing of the request or requirement as soon as
feasible so that such other party may make timely effort to protect or limit the
conditions of disclosure of its Confidential Information). Without limiting the
generality of the foregoing, Sarnoff and Orchid each shall use its commercially
reasonable efforts to obtain confidentiality agreements from its respective
Partners, investors, licensees, sublicensees, subcontractors employees and
agents, similar in scope to this Section 5.3, to protect the Confidential
Information.

     5.4.  Permitted Disclosures. Notwithstanding the provisions of Section 5.3
hereof, Sarnoff and Orchid may, to the extent necessary, disclose and use
Confidential Information, consistent with the rights of Sarnoff and Orchid
otherwise granted hereunder (a) for the purpose of securing institutional or
government approval to clinically test or market any Product, or (b)

                                       20
<PAGE>

for the purpose of securing patent protection for an invention within the scope
of the Patent Rights. This Agreement and the terms hereof may be disclosed by
either Party only to a third party which executes an agreement requiring such
third party to maintain the confidentiality thereof

6.   Infringement.

     6.1.  Notification of Infringement.  Orchid and Sarnoff each shall notify
the other of any infringement or misappropriation by any Person of any Licensed
Technology rights in the Orchid Field and shall provide the other with the
available evidence, if any, of such infringement.  In such case, the respective
officers of Sarnoff and Orchid shall confer to determine in good faith an
appropriate course of action to enforce the Licensed Technology rights or
otherwise abate the infringement thereof.

     6.2.  Enforcement of Licensed Technology Rights.  If the parties have not
agreed on a course of action pursuant to Section 6.1, then if Orchid determines
that enforcement of the Licensed Technology rights in the Orchid Field is
appropriate, Orchid shall have the right, but not the obligation, at its own
expense, to take appropriate action to enforce such rights; provided, however,
that, if Orchid elects to so act, Sarnoff shall have the right to participate in
the enforcement of such rights by agreeing to bear a percentage of the costs of
such enforcement in such amount as the parties shall determine. All amounts
recovered in any action to enforce rights in Licensed Technology in the Orchid
Field undertaken by Orchid, whether by judgment or settlement, shall be retained
by Orchid after reimbursing the expenses borne by both parties in enforcing such
Licensed Technology rights.  If, within six (6) months after notice of
infringement, Orchid has not commenced action to enforce such rights or
thereafter ceases to diligently pursue such action, Sarnoff shall have the
right, at its expense, to take appropriate action to enforce such rights. Orchid
shall have the right to participate separately in such enforcement. All amounts
recovered in any action to enforce Licensed Technology rights undertaken by
Sarnoff solely at its expense, whether by judgment or settlement, shall be
retained by Sarnoff after reimbursing the expenses borne by both parties in
enforcing such Licensed Technology rights. Sarnoff and Orchid shall fully
cooperate with each other in the planning and execution of any action to enforce
rights. Sarnoff shall not enter into any settlement that includes the grant of a
license under, agreement not to enforce, or any statement prejudicial to the
validity or enforceability of any Licensed Technology in the Orchid Field
without the consent of the Orchid.

     6.3.  Disclaimer of Warranty; Consequential Damages.

           6.3.1.  SARNOFF EXPRESSLY DISCLAIMS ANY WARRANTY, EXPRESS OR IMPLIED,
WITH RESPECT TO THE LICENSED TECHNOLOGY, INCLUDING, W1THOUT LIMITATION, ANY
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

           6.3.2.  NEITHER PARTY TO THIS AGREEMENT SHALL BE ENTITLED TO RECOVER
FROM THE OTHER ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, MULTIPLE OR PUNITIVE
DAMAGES.

                                       21
<PAGE>

     6.4   Infringement. In the event that an action for patent infringement is
commenced against Orchid and/or its sublicensees, whether severally or jointly,
based on the manufacture, use or sale of any Product or Service in any country,
Orchid may, without limitation: (i) terminate and revert its license hereunder
to such Product or Service in such country, which shall be deemed an abandonment
of such Product or Service in such country, or (ii) defend such action on
behalf, of the appropriate parties at its own expense.

     6.5   Markings. Set forth in Exhibit A is a list of the Patent Rights,
which list shall be updated from time to time by Sarnoff Orchid shall refer to
this list and affix appropriate markings and legends on Products or Services
sold or distributed by or on behalf of Orchid using such Patent Rights.

     6.6   Limitations. Sarnoff makes no representations or warranties that the
rights granted to Orchid pursuant to Section 2.1 hereof may be exercised by
Orchid and its sublicensees without infringing any third party rights in any
country in the world. Sarnoff assumes no responsibility hereunder for the
manufacturing, product specifications, or end-uses of Products or Services by
Orchid or its customers or sublicensees.  No warranties made by Orchid in
connection with its Products or Services shall expressly or implicitly obligate
Sarnoff in any manner.

     6.7   Product Indemnification.  Subject to the provisions of this Section
6.7, Orchid agrees to defend, indemnify and hold harmless Sarnoff from any and
all damages arising from injury or damage to persons or property (including
without limitation, product liability or infringement of any proprietary rights)
resulting directly or indirectly from Orchid's use, development, manufacture,
licensing, marketing, sale or other disposition or any other commercial
exploitation of any Product or Service, except those which result from the gross
negligence or willful misconduct of Sarnoff.  Sarnoff shall promptly notify
Orchid of any claim which is to be indemnified hereunder and Orchid shall have
the sole right to defend, settle or compromise any such action or claim.

     7.    Term and Termination.

     7.1.  Term.  This Agreement shall be effective as of the Effective Date and
shall continue in full force and effect unless terminated by mutual agreement or
as set forth below.

     7.2.  Termination. In the event Orchid fails to make payments due
hereunder, Sarnoff shall have the right to terminate this Agreement upon ninety
(90) days' written notice, unless Orchid makes such payments within the ninety
(90) day notice period or unless any such payment is contested in good faith, in
which event Sarnoff shall not have the right to terminate this Agreement until
the matter is resolved in Sarnoff's favor pursuant to Section 13 hereof and
Orchid still fails to make any such payment for thirty (30) days after such
resolution.

     7.3.  Survival of Sublicenses.  In the event any license granted to Orchid
hereunder terminates for any reason, any sublicenses granted by Orchid under
this Agreement shall continue.

                                       22
<PAGE>

8.   No Implied Waivers; Rights Cumulative.

     The delay or failure of any Party at any time or times to require
performance of any provisions shall in no manner affect the rights at a later
time to enforce the same. No waiver by any Party of any condition or of the
breach of any term contained in this Agreement, whether by conduct, or
otherwise, in any one or more instances, shall be deemed to be, or considered
as, a further or continuing waiver of any such condition or of the breach of

any respect in any jurisdiction, then, to the fullest extent permitted by law,
(a) all other provisions hereof shall remain in full force and effect in such
jurisdiction and shall be liberally construed in order to carry out the
intentions of the parties hereto as nearly as may be possible and (b) such
invalidity, illegality or unenforceability shall not affect the validity,

            commercial third party for use in the Orchid Field.

            The foregoing:

                 (x) shall not prevent Sarnoff or any of its subsidiaries from
            providing services related to, or from developing, licensing or
            selling (a) Type 2 Storage Devices, or (b) Ancillary Devices, Type 1

            Chips, Type 1 Storage Devices, or Input/Output Devices for Chips or
            Type 1 Storage Devices,

            modification.

2.      2.3  Amendments to Option Grant.

             2.1 (a) Sections 2.3 (paragraphs 2.3.1 - 2.3.5 inclusive), 2.4 and
        2.5 of the License Agreement are deleted in their entirety and the
        following is inserted in their place:

             2.3. The Parties acknowledge that Orchid has exercised the
        exclusive option to include the Genomics Field and the Research Products
        Field in the Orchid Field and to receive exclusive licenses in such
        Option Fields. No other options are granted by Sarnoff to Orchid
        hereunder to the remaining Option Fields, with respect to which
        remaining Option Fields Orchid has and retains a non-exclusive license
        pursuant to the terms and conditions of this Agreement, as amended.

                 2.3.1 The Parties agree that, in consideration of the payments
             to be made and securities to be delivered by Orchid to Sarnoff
             pursuant to Sections 3.1(c) and 3.5 below, as of the Closing Date
             of this Amendment:

                     (i)    Sarnoff will not conduct any further research and
                     development activities for Orchid with respect to the
                     Genomics Field and the Research Products Field; the Funded
                     Research Program in connection with the Genomics Field and
                     the Research Products Field are deemed to be fully paid-up,
                     funded and completed and Orchid does not and will not owe
                     Sarnoff any monies for

                                       34
<PAGE>

                     royalties, option exercise fees or otherwise in connection
                     with such fields;

                     (ii)   no further options are exercisable under the License
                     Agreement; and

                     (iii) the Parties will not engage in any further funded
                     research or development activities in connection with any
                     Option Field, unless under a separate written agreement.

                     2.3.2  Intentionally omitted.

                     2.3.3  Intentionally omitted.

                     2.3.4  Intentionally omitted.

                     2.3.5 Sarnoff has delivered to Orchid and Orchid has
                 accepted a detailed list of all Licensed Technology which, to
                 the best of Sarnoff's knowledge, was invented or developed
                 during the course of the Funded Research Programs, or
                 incorporated in devices or systems as part of any such Funded
                 Research Programs as of the Closing Date. A list which has been
                 mutually agreed upon by the Parties and appended to this
                 Agreement (as amended) (Exhibit A) includes Licensed Technology
                 attributable to such Funded Research Programs as well as other
                 technology licensed hereunder as Research Technology. After the
                 Closing Date, if Sarnoff becomes aware of any Licensed
                 Technology that had not been delivered, Sarnoff will promptly
                 deliver such Licensed Technology to Orchid. If Orchid becomes
                 aware of any Licensed Technology that had not been delivered by
                 Sarnoff on or after the Closing Date in accordance with this
                 Section 2.3.5, Orchid will notify Sarnoff in writing and the
                 parties will negotiate the terms of its delivery to Orchid.

     2.4 Notwithstanding any provision of this Agreement, (a) the failure by
Orchid to exercise any Option which was granted by Sarnoff under this


                                       35

                 Agreement shall not in any way affect any exclusive licenses
                 granted to Orchid hereunder, any non-exclusive licenses granted
                 to Orchid with respect to the HTS Field and the Cell-Based
                 Assay Field and (b) the scope of any licenses granted to Orchid
                 in the SB Agreement shall not be limited or affected in any way
                 by this Agreement.

                 2.5 Section 2.5 of the License Agreement is deleted in its
           entirety and "Intentionally Omitted" is inserted in its place.

        (b) Section 2.6.2 of the License Agreement is deleted in its entirety
and the following is inserted in its place:

                 2.6.2 Unless otherwise agreed in writing, without the prior
          written consent of Sarnoff, Orchid shall not grant a license or
          other right to any third party to use or practice outside the
          Orchid Field any Joint Inventions or Joint Patent Right, or to
          develop, have developed, make, have made, use, have used, offer
          to sell, sell, have sold, import, have imported, lease, or
          otherwise distribute any products or deliver any services
          outside the Orchid Field Covered By Joint Patent Rights. Unless
          otherwise agreed in writing, without the prior written consent of
          Orchid, Sarnoff shall not grant a license or other right to any third
          party to use or practice in the Orchid Field, any Joint Invention or
          Joint Patent Right, or to develop, have developed, make, have made,
          use, have used, offer to sell, sell, have sold, import, have imported,
          lease or otherwise distribute any products or deliver any services,

                            Research Products Field.

          3.3 (c)  Section 3.2 of the License Agreement is deleted in its
      entirety and the following is inserted in its place:

                 3.2  Option Consideration.

4.  AMENDMENT TO DISCLOSURE OF LICENSED TECHNOLOGY.

          Section 5.2.4 of the License Agreement is amended as follows:

                 5.2.4. Sarnoff may, with respect to the Patent Rights, at any
           time, in its sole discretion decide that it desires to discontinue
           its responsibility for the prosecution or maintenance of a particular
           patent application or patent in one or more countries of Patent
           Rights which are Licensed Technology under Section 1.17(a), (b), (c),
           (d), (e) and (g). In such event, Sarnoff shall notify Orchid promptly
           in writing of its intention to discontinue responsibility for the
           prosecution or maintenance for such patent application or patent,
           and, in any event, shall give such notice at least sixty (60) days
           prior to the effective date of such proposed discontinuance in order
           to permit Orchid to determine whether it wishes to assume the
           responsibility therefor. Orchid shall have the right and option, but
           not the
                                       39
<PAGE>

           obligation, to assume responsibility for prosecution and maintenance
           of such patent or patent application which Sarnoff desires to
           discontinue. Orchid shall inform Sarnoff in writing of its decision
           to assume responsibility for prosecution and maintenance of such
           patent or patent application and Sarnoff shall execute and deliver
           such documents and take such actions as are reasonably necessary or
           appropriate to effect such assumption and transfer of responsibility
           in a timely and efficient manner. In the event Orchid exercises such
           right, such patent or patent application shall be assigned to Orchid
           and removed from operation of this Agreement; provided that, Sarnoff
           shall have a royalty free, non-exclusive, worldwide, right and
           license under such Licensed Technology with the right to sublicense,
           to develop, have developed, make, have made, use, have used, import,
           have imported, offer for sale, sell have sold or lease products and
           practice processes outside the Orchid Field and further provided that
           upon termination of this Agreement, such patents and patent
           applications shall be assigned to Sarnoff. However, if Sarnoff elects
           to use or sublicense a particular patent in a particular country
           assigned by Sarnoff to Orchid under this Section 5.2.4, then Sarnoff
           shall pay to Orchid one half of the out of pocket costs expended by
           Orchid in obtaining and maintaining the particular patent in the
           particular country.

5.  INFRINGEMENT.

        There are no modifications to Section 6 of the License Agreement.

6.  TERM.

             agreement.

        6.2  Section 7.2 of the License Agreement is deleted in its entirety and
    "Intentionally Omitted" is inserted in its place.

         warrant (hereinafter the "Warrant") is exercisable, in whole or in part

         at any time during the period commencing on April 13, 2000 (the

     3.  Method of Exercise or Conversion; Payment; Issuance of New Warrant.
         ------------------------------------------------------------------

          (a) Exercise.  Subject to Section 1 hereof, the purchase right
              --------
     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 (i) 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; or (ii) by
     exercise of the Conversion Right under paragraph (b) below.  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 (or exercise of the


                                      43
<PAGE>

     Conversion Right) made for such shares as aforesaid. In the event of any
     exercise of this Warrant and, in any event, certificates for the shares of
     stock so purchased shall be delivered promptly to the Holder hereof (and,
     in any event, 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 promptly to the Holder hereof (and, in any
     event, within fifteen (15) days).

          (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; and
                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 average of the bid and asked prices per share on
     NASDAQ Small-Cap Market or, if not then listed or traded, in the sole
     discretion of the Board of Directors of the Company, any other over-the-
     counter market, including the OTC Bulletin Board, which reports bid, asked
     and last sale prices and volume of sales, averaged over the 10 trading days
     consisting of the day as of which the current fair market value of Common
     Stock is being determined and the nine consecutive business days prior to
     such day.  If at any time such quotations are not available, the current
     fair market value of a share of Common Stock shall be the highest price per
     share which the Company could obtain from a willing buyer (not a current
     employee or director) for shares of Common Stock sold by the Company, from
     authorized but unissued shares, as reasonably determined in good faith by
     the Board of Directors of the Company, unless (i) the Company shall become
     subject to a merger, acquisition or other consolidation pursuant to which
     the Company is not the surviving party, in which case the current fair
     market value of a


                                      44
<PAGE>

     share of Common Stock shall be deemed to be the value received by the
     holders of the Company's Common Stock for each share of Common Stock
     pursuant to the Company's acquisition; or (ii) the Holder shall exercise
     its Conversion Right to purchase such shares within 15 days prior to the
     closing date of the initial underwritten public offering of the Company's
     Common Stock pursuant to a registration statement filed under the Act, in
     which case, the fair market value of a share of Common Stock shall be the
     price per share at which all registered shares are sold to the public in
     such offering. 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 promptly to the holder hereof (and, in any event, 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
     promptly to the holder hereof (and, in any event, within fifteen (15)
     days).

     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
duly authorized, validly issued, fully paid and nonassessable, and free from all
taxes, liens and charges with respect to the issue thereof.  During 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.  The Company will take all such action
as may be necessary to ensure that such shares of Common Stock will be issued
without violation of any applicable law or regulation or of any requirements of
any domestic securities exchange or quotation system upon which the Common Stock
may be traded; provided, however, that the Company shall not be required to
effect a registration under federal or state securities laws with respect to
such exercise.  The Company shall use its best efforts, on and after the date
the Company shall file a registration statement covering the shares of Common
Stock issued upon exercise of this Warrant, to list such shares upon any
securities exchange or quotation system on which the Common Stock is traded.

     5.  Adjustment of Purchase 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, recapitalization, reorganization 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


                                      45
<PAGE>

     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, recapitalization,
     reorganization, 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 (a) 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 (a) 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 (b) or (c)) of, Common Stock, then the Warrant Price shall be
     adjusted, from and after the date of determination of stockholders 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 (a) the numerator of which shall be the total
     number of shares of Common Stock outstanding immediately prior to such
     dividend or distribution and (b) the denominator of which shall be the
     total number of shares of Common Stock outstanding immediately after such
     dividend or distribution.

          (d) Cash Dividends and Distributions.  If at any time or from time to
              --------------------------------
     time the holders of Common Stock (or any shares of stock or other
     securities at the time receivable upon the exercise of this Warrant) shall
     have received or become entitled to receive, without payment therefor, any
     cash, stock, other securities or property, the holder hereof shall, upon
     the exercise of this Warrant, receive, in addition to the number of shares
     of Common Stock receivable thereupon, and without payment of any additional
     consideration therefor, the amount of cash, stock, other securities and
     property which such holder would have received had he been the holder of
     record of such Common Stock as of the date on which holders of Common Stock
     received or became entitled to receive such cash, stock, other securities
     and property.


                                      46
<PAGE>

          (e) 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.  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 registration under
applicable state securities laws is not required and (ii) if reasonably
requested by the Company, an opinion of counsel reasonably 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 to or succeeded by any
     person; 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.

          (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


                                      47
<PAGE>

     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.  Liquidating Dividends.  If the Company pays a dividend or makes a
          ---------------------
distribution on the Common Stock payable otherwise than in cash out of earnings
or earned surplus (determined in accordance with generally accepted accounting
principles) except for a stock dividend payable in shares of Common Stock (a
"Liquidating Dividend"), then the Company will pay or distribute to the holder
of this Warrant, upon the exercise hereof, in addition to the Common Stock
purchased upon such exercise, the Liquidating Dividend which would have been
paid to such holder if he had been the owner of record of such shares of Common
Stock immediately prior to the date on which a record was taken for such
Liquidating Dividend or, if no record was taken, the date as of which the record
holders of Common Stock entitled to such dividends or distribution were
determined.

     11.  Miscellaneous.
          -------------

          (a) No Rights as Shareholder.  Except as provided in the Agreement, no
              ------------------------
     holder of the Warrant or Warrants 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
     stockholder of the Company or any right to vote for the election of
     directors or upon any matter submitted to stockholders 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 the Warrant or
     Warrants shall have been exercised and the shares purchasable upon the
     exercise hereof shall have become deliverable, as provided herein.

          (b) 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.

          (c) Notice of Capital Changes.  In case:
              -------------------------

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


                                      48
<PAGE>

               (ii) there shall be any capital reorganization or
          reclassification of the capital stock of the Company, or consolidation
          or merger of the Company with, or sale of all or substantially all of
          its assets to, another corporation or business organization in which
          the holders of the Company's voting securities before the transaction
          beneficially own less than 50% of the voting securities of the
          surviving entity; or

               (iii)  there shall be a voluntary or involuntary dissolution,
          liquidation or winding up of the Company;

     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, of the date on which a record shall be taken for such dividend, or
     distribution or for determining stockholders 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
     30 days prior to the transaction in question and not less than 20 days
     prior to the record date in respect thereof.

          (d) 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
     upon the earlier of delivery thereof by hand delivery, by courier, or by
     standard form of telecommunication or three (3) business days after the
     mailing thereof if sent registered mail with postage prepaid, addressed to
     the Company at its principal executive offices and to the holder at its
     address set forth in the Company's books and records or at such other
     address as the holder may have provided to the Company in writing.

          (e) No Impairment.  The Company will not, by amendment of its
              -------------
     Certificate of Incorporation or through any reorganization,
     recapitalization, reclassification, transfer of assets, consolidation,
     merger, dissolution, issue or sale of securities or any other voluntary
     action, avoid or seek to avoid the observance or performance of any of the
     terms to be observed or performed hereunder by the Company, but will at all
     times in good faith assist in the carrying out of all the provisions in the
     Warrant.

          (f) Governing Law.  This Warrant shall be governed by and construed
              -------------
     under the laws of the State of Delaware.

          (g) Issue Tax.  The issuance of certificates for shares of Common
              ---------
     Stock upon the exercise of the Warrant shall be made without charge to the
     holder of the Warrant for any issue tax in respect 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 certificate in a name other than that of the then holder of the Warrant
     being exercised.

          (h) Amendments and Waiver. Any term of this Warrant may be amended or
              ---------------------
     waived only with the written consent of the Company and by a majority in
     interest of the holders of


                                      49
<PAGE>

     outstanding Warrants of the Company issued under the Purchase Agreement
     (determined by reference to the number of shares underlying such Warrants).
     In the event that such required consent is obtained, such amendment or
     waiver shall be binding on the holder of this Warrant, the other Warrants
     and such holders' assigns. Any such waiver of a breach of any provision of
     this Warrant shall not operate as or be construed to be a waiver of any
     other breach of such provision or of any breach of any other provision of
     this Warrant.

          (i) Automatic Conversion.  In the event that the holder of this
              --------------------
     Warrant has not exercised this Warrant or any portion hereof as of the
     expiration date hereof and on such date the Warrant Price is less than the
     fair market value of the Company's Common Stock, the holder of this Warrant
     shall be deemed to have exercised this Warrant in accordance with the
     Conversion Right under Section 3(b) as of the date of expiration of the
     Warrant.



IN WITNESS WHEREOF, this Warrant is executed as of this 13th day of April, 2000.

2.   License

     2.1   NEN grants to Orchid an exclusive, royalty free, worldwide right and
           license in and to the NEN Patents to manufacture, distribute, sell
           and use Kits (with the right to grant sub-licenses to resellers who
           are not Orchid distributors to sell Kits and to end-users to use
           Kits) solely for the detection of genetic polymorphisms by GBA. The
           right and license to manufacture granted in this provision does not
           include the right to manufacture Terminators except as provided in
           paragraphs 3.4.3 and 3.10.2. NEN further grants to Orchid a non-
           exclusive, royalty free, worldwide right and license in and to the
           NEN Patents to use Terminators, other than ddNTPs, (with the right to
           grant sub-licenses) alone for GBA.

     2.2   Orchid has been a distributor of ddNTPs purchased from NEN since
           January 1, 1998, and, as such a distributor, has had and will
           continue to have the right to use and sell ddNTPs purchased by Orchid
           from NEN.

     2.3   The right to grant sub-licenses under paragraph 2.1 to end-users to
           use Terminators, other than ddNTPs, alone and not as a component or
           part of a Kit is limited to the use by each end-user of no more than
           one (1) micromole of Terminators in any consecutive twelve (12) month
           period.

     2.4   Notwithstanding paragraph 2.3, in the event Orchid no longer
           manufactures, distributes, sells or uses Kits, then Orchid will have
           a non-exclusive, royalty-free, worldwide right and license in and to
           the NEN Patents to distribute, sell and use Terminators purchased
           from NEN(with the right to grant sub-licenses) alone for GBA.

3.   Supply of Terminators

     3.1  Purchase

          3.1.1  During the Term of this Agreement, NEN will sell to Orchid, and
                 Orchid will purchase from NEN all of Orchid's requirements of
                 Terminators, except as provided by paragraphs 3.4.3 and 3.10.2.

          3.1.2  All purchase orders placed by Orchid with NEN for Terminators
                 under this Agreement shall be in writing. The purchase orders
                 are subject and subordinate to and do not vary the terms and
                 provisions of this Agreement which, if other or different than
                 those of the purchase order, will be controlling even if the
                 purchase order is accepted and filled by NEN.

          3.1.3  All purchase orders will be accepted on receipt unless NEN
                 notifies Orchid within ten (10) days of receipt of the purchase
                 order that NEN cannot or will not fill the purchase order.

          3.1.4  Orchid agrees to provide NEN on the date that this Agreement is
                 signed by Orchid, and thereafter by the last business day of
                 each following calendar quarter, with a written, good faith,
                 rolling twelve (12) month, non-binding monthly forecast of its
                 expected purchases of Terminators. No forecast can increase the
                 purchase quantity forecasted for the first quarter over the
                 quantity forecasted in the last previous forecast for that
                 quarter by more than the lesser of [*][[*]] percent ([*][[*]]%)
                 of the last previous forecast for that quarter and [*][[*]]
                 micromoles.

          3.1.5 Orchid agrees to place within fifteen (15) calendar days from
                 the date Orchid signs this Agreement a binding, non-cancelable
                 purchase order with NEN to purchase at least two hundred fifty
                 thousand dollars ($250,000) of Terminators for the year 2000;
                 such purchase order not to be deferrable beyond December 31,
                 2000.

          3.1.6  Orchid agrees that it shall not, in any purchase order placed
                 with NEN pursuant to this Agreement or in any instructions or
                 other communication related thereto, specify a release or
                 shipment date to NEN with respect to any order or any portion
                 thereof such that the period from the date of submission of
                 order to (i) the release date is less than the NEN Build-to-
                 Ship Lead Time in effect as of the date of the submission of
                 the order and (ii) the delivery date is less than the NEN
                 Build-to-Ship Lead Time in effect as of the date of the
                 submission of the order plus one (1) business day.

          3.1.7  Orchid may defer or cancel delivery of any portion or all of
                 the Terminators specified in a purchase order by notifying NEN
                 at least three (3) business days prior to the requested
                 delivery date; provided that any such deferment or cancellation
                 shall not result in Orchid not meeting its purchase commitment
                 set forth in paragraph 3.1.5.

     3.2  Minimum Orders

          3.2.1  During the Term of this Agreement, Orchid will order and take
                 delivery of the following minimum quantities of Terminators
                 from NEN:

                 (1) During the first twelve (12) month period following the
                     Effective Date:

                         two hundred (200) micromoles;

                 (2) During the second twelve (12) month period:

                         five hundred (500) micromoles;

                 (3) During the third twelve (12) month period:

                         seven hundred fifty (750) micromoles;

                 (4) During the fourth twelve (12) month period, and each
                     subsequent twelve (12) month period:

                         one thousand (1,000) micromoles.

          3.2.2  In the event that Orchid fails to order and take delivery of
                 the minimum quantity of Terminators in a twelve-month period,
                 Orchid will pay to NEN, within thirty (30) days after receipt
                 of an invoice therefore at the end of that twelve-month period,
                 a sum equal to the purchase price of the quantity of
                 Terminators by which Orchid failed to reach the minimum
                 quantity, calculated as if such quantity of Terminators were
                 purchased in a single order for single delivery at the average
                 price chargeable for all Terminators in such single order
                 quantity for that twelve-month period.

          3.2.3  If this Agreement is terminated by NEN without cause or by
                 Orchid for cause (as the term "cause" is used in section 14 of
                 this Agreement) or pursuant to paragraph 14.2 prior to the end
                 of a twelve-month period, the minimum quantity of Terminators
                 Orchid is obligated to order and take delivery from NEN for
                 that twelve-month period will be pro-rata reduced in proportion
                 to the time the Agreement was not in effect during the twelve-
                 month period.

          3.2.4  Receipt of payment of the sum set forth in paragraph 3.2.2 is
                 NEN's sole

                                       5
<PAGE>

                 and exclusive remedy for any failure of Orchid to order from
                 NEN any quantity of Terminators, but not for any failure of
                 Orchid to meet its purchasing obligations under paragraph 3.1.5
                 or for any failure of Orchid to accept delivery of any quantity
                 of Terminators ordered if such order is not timely deferred or
                 canceled pursuant to paragraph 3.1.7.

          3.2.5  The minimum quantity of Terminators of Orchid's purchase
                 commitment set forth in paragraph 3.2.1 for any given twelve-
                 month period, or shorter period if the Agreement is terminated,
                 shall be reduced to the extent that, during that twelve-month
                 period, (a) NEN is unable or fails for any reason to supply or
                 deliver a quantity of Terminators against an order submitted by
                 Orchid and Orchid is not in material breach of this Agreement,
                 unless such inability or failure is by reason of (i) Orchid not
                 complying with the provisions of paragraph 3.1.6 or (ii)
                 Orchid's failure to place and not cancel or defer beyond the
                 period in question purchase orders for delivery of the minimum
                 quantity, (b) Orchid purchases Third Party Terminators as
                 provided by paragraph 3.4.3, and (c) Orchid manufactures or
                 obtains from another source Terminators as provided by
                 paragraph 3.10.2.

     3.3  Preferred Terminators

          3.3.1  Orchid and NEN mutually prefer that, at some future time,
                 Orchid will have no need for ddNTP Terminators and that NEN
                 will supply and sell to Orchid all acyNTP Terminators needed.

          3.3.2  Both Orchid and NEN, however, recognize that at present Orchid
                 needs [*] Kits and GBA instrumentation.

          3.3.3  Orchid will use Commercially Reasonable Efforts to diligently
                 refine and develop Kits and GBA instrumentation.

          3.3.4  NEN will use Commercially Reasonable Efforts to diligently
                 refine and develop acyNTP Terminators for optimal use in Kits
                 and Orchid's present and future GBA instrumentation.

          3.3.5  Until such time as Orchid's Kits and GBA instrumentation make
                 optimal use of acyNTP Terminators to the satisfaction of Orchid
                 and Orchid's customers, to the extent manufactured by NEN, NEN
                 will continue to supply and sell to Orchid ddNTP Terminators
                 and other Terminators under this Agreement.

     3.4  Improved Terminators

          3.4.1  NEN will promptly notify Orchid of any new Terminators
                 developed by or for it, or supplied to it, when any such new
                 Terminator is ready for evaluation, and will provide samples of
                 such new Terminators for Orchid to determine whether the new
                 Terminator is an improvement (in price or performance) over
                 existing Terminators.

          3.4.2  NEN will offer for sale to Orchid any new Terminators developed
                 by or for it, or supplied to or manufactured by it, and will
                 sell such new Terminators to Orchid, if Orchid so desires, on
                 mutually agreeable terms and conditions; such terms and
                 conditions to be no less favorable than those by which NEN may
                 sell such new Terminator to any third party and include a
                 provision that NEN will not sell such new Terminator to any
                 third party in quantities of [*] micromoles or more for use in
                 genotyping applications at a price that is less than [*]
                 percent ([*]%) of the price charged Orchid for equivalent
                 quantities of that Terminator.

          3.4.3  In the event that, at any time during the Term of this
                 Agreement, any third party sells or offers to sell any chain
                 terminators for a DNA/RNA polymerase reactions ("Third Party
                 Terminator") which is not subject of a claim of a NEN Patent,
                 and which, in Orchid's reasonable judgment, is an improvement
                 (in price for similar quantities to be purchased or
                 performance) over a Terminator then sold to Orchid by NEN,
                 Orchid may meet any or all of its requirements for Terminators
                 through purchase of Third Party Terminators from the third
                 party.

          3.4.4  Orchid's right to purchase Third Party Terminators from third
                 parties notwithstanding the provisions of paragraph 3.1.1 may
                 not be exercised until NEN has been afforded thirty (30) days
                 to make an offer to sell to Orchid Terminators which are, in
                 Orchid's sole and reasonable judgment, at least equal or better
                 in price and performance to the Third Party Terminators offered
                 by the third party. The thirty (30) day period mentioned in
                 this provision shall not begin until Orchid has advised NEN in
                 writing of the performance and/or price specifications of the
                 Third Party Terminator and the basis on which Orchid has
                 concluded that the Third Party Terminator is an improvement
                 over a Terminator then sold to Orchid by NEN.

     3.5  Delivery

          3.5.1  Time of Delivery

                 (1) NEN's obligation of delivery is and will remain on a best
                     efforts basis. NEN will use its best efforts to deliver to
                     Orchid such quantity of Terminators or any portion thereof
                     on or before the date requested in Orchid's purchase order;

                     in material breach of this Agreement and each such purchase
                     order and other written communication from Orchid to NEN as
                     to the delivery of such quantity or any portion thereof is
                     in compliance with paragraphs 3.1.6.

                 (2) Orchid may cancel any purchase order, in whole or in part
                     if not delivered on time.

                 (3) In case of deliveries that would be late if shipped through
                     normal shipment channels, Orchid may require NEN to ship by
                     express and NEN will pay the difference between the freight
                     and the express rate.

          3.5.2  NEN will ship Terminators, freight prepaid, F.O.B. NEN's
                 facility at 549 Albany Street, Boston, Massachusetts.

          3.5.3  Orchid will be invoiced for all taxes assessed and NEN's
                 standard handling fee in lieu of all shipping charges, freight,
                 insurance, special handling (where required) and similar costs.

     3.6  Price

          3.6.1  Price Schedule

                 (1) The price schedule for Terminators is on attached Schedule
                     3.6.1(1). The prices are for Terminators defined as either
                     ddNTPs or acyNTPs and each group has attached either a
                     hapten or dye marker and are for single shipment orders.
                     Quantities of different Terminators within each grouping
                     and marker type ordered in the same purchase order and
                     shipped in a single shipment may be added to determine the
                     lowest unit price for that grouping.

                 (2) Orchid will be entitled to the single shipment price even
                     in the event NEN is unable, or unwilling, to ship an order
                     in a single shipment if the Terminators have been ordered
                     by Orchid in a single purchase order with a specified
                     preference in said purchase order for a single shipment of
                     all Terminators ordered.

                 (3) The prices for acyNTP Terminators are discounted from the
                     prices for ddNTP Terminators based on their having equal
                     biological performance. This discount may be adjusted by
                     mutual agreement of the parties to reflect any inequity in
                     performance, but NEN agrees that, during the Term of this
                     Agreement, the prices for acyNTP Terminators will always be
                     at discounted prices from those charged by NEN for ddNTP
                     Terminators.

          3.6.2  (1) The prices set forth on attached Schedule 3.6.1(1) are most
                     preferred customer prices exclusive to Orchid in the field
                     of genotyping and represent a discount from the prices NEN
                     will charge any third party for the same or lesser quantity
                     per order of any terminator for us in genotyping
                     applications as to any order for more than [*] per order.

                 (2) In consideration for the exclusivity of the most preferred
                     customer prices, Orchid will pay to NEN a one-time only,
                     non-refundable, non-creditable, lump sum, fee of seven
                     hundred fifty thousand dollars ($750,000) within five (5)
                     business days of the Effective Date.

                 (3) If at any time in a given calendar year during the term of
                     this Agreement, NEN should sell Terminators to any third
                     party in single order quantities of [*] or more for use in
                     genotyping applications at a price that is less than [*] of
                     the price charged or offered to Orchid for purchase by a
                     single order of equivalent quantities of Terminators, then
                     NEN will immediately (i) notify Orchid of such sale and
                     (ii) adjust the price charged Orchid such that the price of
                     sale to the third party is at least [*] of the adjusted
                     price to Orchid, refund the difference in price paid by
                     Orchid for any order filled by NEN on or after the date of
                     such sale, and offer the adjusted price to Orchid for
                     accepted and unfilled orders and future orders. (By way of
                     example, and not limitation, if the price to Orchid for a
                     single order of [*] to [*] micromoles of Terminators is
                     $[*] per micromole and NEN sells [*] micromoles of
                     Terminators for use in genotyping to a third party for $[*]
                     per micromole in fulfillment of a single order, the price
                     to Orchid for each single order for [*] to [*] micromoles
                     of Terminators will be adjusted to $[*] per micromole.)

          (1) NEN, at any time after one (1) year from the Effective Date of
              this Agreement, may increase its prices (and amend Schedule
              3.6.1(1) accordingly) if it incurs extraordinary increases in its
              cost of delivering (including manufacture) Terminators to Orchid
              by giving Orchid thirty (30) days prior written notice of such
              price change and documentation demonstrating the extraordinary
              costs. Prices may be increased by any amount up to [*] of that
              Terminator before NEN incurred the extraordinary cost. For the
              purpose of this provision, "extraordinary increases" in cost of
              delivery means a cumulative increase during the term hereof in
              NEN's total cost of delivery (including manufacture) of more than
              [*] percent ([*]%) since the latter of the Effective Date or the
              last previous price adjustment pursuant to this paragraph.

          (2) Orders accepted by NEN prior to the effective date of any price
              increase will be invoiced at the accepted price and will not be
              subject to the price increase.

          (3) As of the effective date of any price increase to Orchid, the
              prices charged third parties will be adjusted by NEN such that
              they are at least [*] percent ([*]%) of the increased price to
              Orchid for equivalent quantities of the same Terminator.

     3.7  Premium

          3.7.1 In addition to the price to be paid to NEN for Terminators set
                forth in paragraph 3.6.1, Orchid shall pay to NEN within thirty
                (30) days of the last day of each calendar year during the term
                of this Agreement a share of the Net Sales Revenues received by
                Orchid during that year based on the [*] A separate calculation
                shall be done as to each Kit sold during the year. The sum of
                all such calculations shall be the amount that Orchid shall pay
                to NEN. To the extent that the result of any calculation based
                on sales of a given Kit is $0 or less, that result, when summing
                the results of all the calculations shall be deemed to be $0 and
                not a negative number. Net Sales Revenues from the purchase of
                any Kit will not offset Net Sales Revenues from another Kit.
                With respect to any Net Sales Revenues received in currencies
                other than U.S. Dollars, all amounts shall be converted into
                U.S. Dollars in accordance with generally accepted accounting
                principles, consistently applied before using the formula set
                forth in this paragraph.

                 (1)

          3.7.2  Orchid shall, for a period of at least three (3) years after
                 any report required by paragraph 3.7.3, maintain at its
                 principal place of business true and complete books of account,
                 records and other data (hereinafter "Records") containing all
                 particulars reasonably necessary to determine the amounts
                 payable by Orchid to NEN at the end of each year pursuant to
                 paragraph 3.7.1. During such three-years periods, NEN shall
                 have the right to engage an independent, nationally-recognized
                 accounting firm, reasonably acceptable to Orchid, which firm
                 may examine during normal business hours and at times
                 reasonably acceptable to Orchid, on at least two (2) weeks
                 prior written notice, such Records reasonably necessary to
                 verify the accuracy of any amounts paid by Orchid to NEN
                 pursuant to paragraph 3.7.1; provided, however, that such
                 examination shall not take place more often than once per year
                 and shall not cover such Records for more than the preceding
                 three (3) years and provided further that such accounting firm
                 shall report only to NEN and Orchid only as to the accuracy of
                 the payments and the reports thereof and shall not disclose any
                 other information to NEN or any third party disclosed,
                 discerned or derived from the examination. In the event any
                 examination on behalf of NEN of Orchid's Records disclose
                 underpayment to NEN which for any year exceeds [*] percent
                 ([*]%) of the amount theretofore actually paid by Orchid to NEN
                 with respect to such year, Orchid shall reimburse NEN on demand
                 for the reasonable and documented costs and expenses,
                 including, but not limited to, all professional fees, incurred
                 in connection with any such examination and shall compensate
                 NEN in an amount equal to the sum of the amount of the
                 underpayment and all applicable late fees.

          3.7.3  The payments set forth in paragraph 3.7.1 shall, if overdue,
                 bear interest until payment at an annual rate of [*] percent
                 ([*] %) computed from the date when the payment became overdue;
                 provided, however, that if such [*] percent ([*] %) rate shall
                 be in excess of that allowed by applicable law, then the
                 highest rate permitted by law shall apply.

     3.8  Payment

          3.8.1  Payments will be made in United States Dollars within thirty
                 (30) days of the invoice date or the shipment date, whichever
                 is later.

                 (1) Late payments shall bear interest at the prime rate as
                     published in The Wall Street Journal on the first business
                     day of each month in which the payment is late plus two
                     percent (2%), and calculated on the basis of a three
                     hundred sixty (360) day year.

     3.9  Inspection and Return or Refund

          3.9.1  Within thirty (30) days of delivery, Orchid may conduct
                 acceptance

                 testing or verification by [*] that received Terminators are in
                 conformance with Specifications, are not defective, and are in
                 good order and condition.

          3.9.2  At Orchid's option, NEN will promptly replace, or refund any
                 payment made on, any Terminator that is in nonconformance with
                 Specifications, defective or not in good order or condition.

          3.9.3  Orchid will as directed by NEN either destroy or return, at
                 NEN's expense, Terminators that do not conform to their
                 Specifications, are defective, or are not in good order or
                 condition.

          3.9.4  Orchid's right to replacement or refund does not limit its
                 rights under paragraph 3.10.2.

     3.10 Allocation and Alternate Source

          3.10.1  In the event that demand for any Terminator should at any time
                  exceed NEN's capacity to fill and deliver all of its orders
                  (and its own need for Terminators), NEN will notify Orchid of
                  the excess demand. Until such time as the excess demand abates
                  or NEN's capacity becomes sufficient to meet such demand, NEN
                  will have the right to equitably allocate its available
                  supplies, manufacturing capacity, inventory and other
                  resources, among Orchid, itself and its other customers.

          3.10.2  In the event NEN is unable for any reason, other than by
                  reason of Orchid placing orders that fail to comply with the
                  provisions of paragraph 3.1.6, to supply Orchid's total
                  requirements of Terminators for [*] ([*]) days from the
                  delivery date set out in Orchid's purchase order, Orchid may
                  itself manufacture or obtain from any other source any portion
                  or all of its requirements for Terminators for so long as NEN
                  is unable to supply all of Orchid's requirements and for [*]
                  months from the date NEN notifies Orchid it is once again able
                  to meet all of Orchid's requirements. NEN will provide Orchid
                  with technical assistance and information as may be reasonably
                  required by Orchid to establish an alternate source of
                  Terminators, including, but not limited to the right to
                  manufacture Terminators.

4.   Collaborative Research Program

     4.1  The parties shall, within [*] days from the Effective Date negotiate
          in good faith a collaborative research program agreement.

5.   Patent Enforcement

     5.1  In the event either party learns that any third party is or might be
          infringing, or preparing to infringe, any NEN Patent or Orchid Patent,
          it will promptly notify the other of such third-party activity.

     5.2  Each party will be solely responsible for and have the sole right of
          taking any action against infringement of a patent or other
          proprietary right which is exclusive to it, at its expense and for its
          benefit. Neither party, however, has any obligation to take any action
          against any infringement.

6.   Labeling

     6.1  Orchid will mark or label in an appropriate manner each Kit it sells
          containing a Terminator encompassed by a claim of a NEN Patent with a
          patent notice in accordance with the provisions of 35 U.S.C. (S) 287.

     6.2  Orchid will label or mark in an appropriate manner each Kit it sells
          containing an acyNTP Terminator(s) supplied by NEN with a statement
          that the Kit incorporates a reagent(s) manufactured and supplied by
          NEN.

     6.3  Orchid also will label or mark in an appropriate manner each Kit it
          sells containing an acyNTP Terminator with the respective language set
          forth in attached Schedule 6.3.

     6.4  For each Kit Orchid will display NEN's logo in an appropriate manner.

     6.5  At NEN's earliest opportunity, but in no event later than ninety (90)
          days from the Effective Date, NEN will label or mark in an appropriate
          manner each Terminator (and in all marketing, advertising, promotional
          and sales materials, whether print or electronic media, which
          materials relate to the use of Terminators for genotyping) it sells to
          any third party which may be used to practice any method encompassed
          by a claim of an Orchid Patent with the language set forth in attached
          Schedule 6.5.

7.   Use of Names

     7.1  Except as obligated by section 6, nothing in this Agreement confers to
          either party any right to use in publicity, advertising, promotion, or
          marketing any name, trade name, trade mark or other designation of the
          other party, without the other party's prior permission, such
          permission not to be unreasonably withheld.

     7.2  Neither Orchid nor NEN will advertise, promote, market or sell any
          product (including Terminators and Kits) under any trade name, trade
          mark or trade dress which is the same as, or confusingly similar to,
          any trade name, trademark, or trade dress in which the other, or its
          Affiliates, have a prior and existing interest, whether as owner,
          licensee or licensor.

8.   Confidentiality

     8.1  Both NEN and Orchid will keep confidential all (i) prices and price
          schedules, (ii) information received from the other that is identified
          in writing as being confidential or proprietary at the time it is
          delivered or communicated, and (iii)

                                       12
<PAGE>

          information of the other which is delivered or disclosed in
          performance of this Agreement and within thirty (30) days from and
          after disclosure is identified in writing by the disclosing party to
          the recipient as confidential, (collectively, and individually,
          "Confidential Information").

     8.2  Orchid and NEN will not disclose any Confidential Information of the
          other to any person or party other than to employees, consultants or
          agents of NEN and of its Affiliates or employees, consultants or
          agents of Orchid and of its Affiliates engaged directly or indirectly
          in activities related to the supply of Terminators or the
          Collaborative Research Program and who have been properly instructed
          to and have agreed in writing to maintain the Confidential Information
          in confidence.

     8.3  Orchid and NEN will take all steps as are reasonably required to
          ensure that all persons to whom it is authorized to disclose
          Confidential Information of the other will not disclose the same to
          any unauthorized person.

     8.4  Either Orchid or NEN, however, may disclose:

                                       13
<PAGE>

          8.4.1  Confidential Information of the disclosing party that is known
                 to the receiving party prior to the time of its disclosure or
                 communication thereto, to the extent evidenced by written
                 records;

          8.4.2  Confidential Information of the disclosing party that is
                 disclosed to the receiving party by a third party not under an
                 obligation of confidentiality;

          8.4.3  Confidential Information that becomes published or otherwise
                 part of the public domain other than as a result of acts by the
                 receiving party not authorized by this Agreement or otherwise
                 authorized by the disclosing party; and

          8.4.4  Confidential Information that is required to be disclosed by
                 order of any governmental authority or court of competent
                 jurisdiction, provided, if the receiving party becomes legally
                 compelled to disclose Confidential Information of the
                 disclosing party, the receiving party will provide the
                 disclosing party with prompt notice so that the disclosing
                 party may seek a protective order or other appropriate remedy
                 and/or waive compliance with the provisions of this Agreement,
                 and, if in the absence of a protective order or the receipt of
                 a waiver, the receiving party nevertheless is legally required
                 to disclose Confidential Information of the other to any
                 governmental authority or court of competent jurisdiction or
                 else stand liable for contempt or suffer other censure or
                 penalty, the receiving party may disclose such Confidential
                 Information, to the most limited extent feasible, without
                 liability under this Agreement.

     8.5  The obligations of this section 8 survive any termination or
          expiration of this Agreement.

9.   Option to Manufacture

     9.1  In the event that Orchid decides to engage a third party to
          manufacture Kits for it, Orchid will notify NEN and afford NEN the
          opportunity to make an offer to manufacture Kits for Orchid. At the
          same time Orchid may solicit and entertain offers from third parties
          for the manufacture of Kits. However, Orchid may not accept any third-
          party offer until thirty (30) days after it offers the same terms and
          conditions as the third-party offer to NEN and NEN has not accepted
          such terms and conditions. The option and rights provided by this
          paragraph are personal to NEN and may not be sub-licensed or otherwise
          transferred without the prior express written approval of Orchid.

     9.2  Notwithstanding paragraph 9.1, Orchid agrees not to engage any third
          party to manufacture for it any Kit containing a Terminator supplied
          to Orchid by NEN.

10.  Equity Investment

                                       14
<PAGE>

     10.1 On or before the date Orchid fulfills its payment obligation under
          paragraph 3.6.2(2) to NEN, NEN will purchase one hundred twenty-five
          thousand (125,000) shares of Orchid common stock, par value $0.001 per
          share, at six dollars ($6.00) per share for an aggregate purchase
          price of seven hundred fifty thousand dollars ($750,000), pursuant to
          the terms and conditions set forth in the Common Stock Purchase
          Agreement to be executed between Orchid and NEN in substantially the
          form attached as Schedule 10.1. The parties acknowledge that the per
          share purchase price includes a premium over current fair market value
          of Orchid's Common Stock as partial consideration for the obligations
          of Orchid set forth herein.

11.  Announcements

     11.1 NEN and Orchid will together draft and make public a joint press
          release announcing their execution of this Agreement and its general
          terms, but not any prices or price schedules, within ten (10) days of
          execution of this Agreement by both parties.

     11.2 Any further public announcements of the existence, terms or
          performance of this Agreement will be at times and in manners as NEN
          and Orchid may mutually agree.

     11.3 Nothing in this Agreement, however, prevents either party from making
          any public announcement which it is or becomes legally obligated to
          make.

12.  Warranties

     12.1 NEN warrants that, at the time of shipment, any Terminator supplied or
          sold to Orchid will (i) be free and clear of all liens and
          encumbrances, with NEN having good title thereto, (ii) be free from
          any defects in materials and workmanship, and (iii) conform to its
          Specifications. NEN warrants that the sale of any Terminator delivered
          hereunder will not infringe the claims of any patent covering the
          Terminators themselves, but does not warrant against infringement by
          reason of the use thereof in combination with other products or in the
          operation of any process. Unless stated elsewhere in this Agreement,
          NEN MAKES NO OTHER WARRANTY, EXPRESSED OR IMPLIED, WITH RESPECT TO THE
          PRODUCTS INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY
          PARTICULAR PURPOSE. Notification of any breach of warranty under (ii)
          and (iii), above, must be made within thirty (30) days of Orchid's
          receipt of the order unless otherwise provided in writing by NEN. No
          claim shall be honored if Orchid fails to notify NEN within the period
          specified. THE SOLE AND EXCLUSIVE REMEDY OF ORCHID FOR ANY LIABILITY
          OF NEN OF ANY KIND INCLUDING LIABILITY BASED UPON WARRANTY (EXPRESSED
          OR IMPLIED, WHETHER CONTAINED HEREIN OR ELSEWHERE), STRICT LIABILITY,
          CONTRACT, OR OTHERWISE IS LIMITED TO THE REPLACEMENT OF THE GOODS OR
          THE REFUND OF THE INVOICE PRICE OF THE GOODS. NEN SHALL

                                       15
<PAGE>

           NOT IN ANY CASE BE LIABLE FOR SPECIAL, INCIDENTAL, OR CONSEQUENTIAL
           DAMAGES OF ANY KIND.

     12.2  NEN represents and warrants that none of the NEN Patents are the
           subject of any litigation and that it is not aware of any
           infringement of any of the NEN Patents.

     12.3  NEN MAKES NO WARRANTY OR REPRESENTATION THAT ANY COMBINATION OF A
           TERMINATOR WITH ANY OTHER PRODUCT, OR ANY USE OF A TERMINATOR WILL
           NOT INFRINGE ANY PATENT, TRADE SECRET OR OTHER PROPRIETARY RIGHT,
           FOREIGN OR DOMESTIC, OF ANY THIRD PARTY.

     12.4  THERE ARE NO OTHER WARRANTIES, EXPRESS OR IMPLIED, RESPECTING
           TERMINATORS AND NONE ARE CREATED, WHETHER UNDER THE UNIFORM
           COMMERCIAL CODE, CUSTOM OR USAGE IN THE INDUSTRY OR THE COURSE OF
           DEALINGS BETWEEN THE PARTIES.

13.  Indemnification

     13.1  NEN agrees to indemnify, defend, and hold harmless Orchid, its
           Affiliates and their directors, officers, agents, employees,
           representatives and assigns, from and against all liabilities,
           damages, expenses and losses (including reasonable attorney fees and
           costs), arising out of (i) the negligent actions of NEN, its
           employees or any third party acting on behalf or under authority of
           NEN in the performance of this Agreement, (ii) any alleged patent
           infringement, contributory patent infringement, inducing patent
           infringement, or trade secret infringement based on Orchid's purchase
           or sale pursuant to the provisions of this Agreement of the
           Terminators. At any time during the course of any action involving a
           Terminator, or if in NEN's opinion a Terminator is likely to become
           the subject of a patent infringement claim, NEN may at its option and
           expense, (i) procure for Orchid the right to continue using and
           selling pursuant to the provisions of this Agreement the Terminator,
           (ii) replace or modify the Terminator so that it becomes non-
           infringing or (iii) accept return of the Terminator and refund the
           purchase price.

     13.2  NEN will not be liable to Orchid under paragraph 13.1 if the patent
           or trade secret infringement claim is based on an alteration or
           modification of the Terminator.

     13.3  Orchid agrees to indemnify, defend and hold harmless NEN, its
           Affiliates, and their directors, officers, agents, employees, and
           assigns, from and against all liabilities, demands, damages, expenses
           and losses (including reasonable attorney fees and costs) arising out
           of (i) the negligent actions of Orchid, its employees or any third
           party acting on behalf or under authority of Orchid in the
           performance of this Agreement, (ii) any sale or use by Orchid of any
           Kit or Terminator, except those liabilities, demands, damages,
           expenses and losses resulting from NEN's (or its employees' or
           agents') negligence, willful misconduct or breach of any
           representation or warranty and (iii) any alleged patent infringement,
           contributory

                                       16
<PAGE>

           patent infringement, inducing patent infringement, or trade secret
           infringement based on Orchid's use of the Terminators.

     13.4  A party seeking indemnification under this Agreement will give prompt
           written notice to the indemnifying party of the commencement of any
           action (and any prior claims relating to such action) for which the
           party seeks indemnification. An indemnifying party will have no
           liability or responsibility of any kind to the party seeking the
           indemnification if it is not promptly notified.

     13.5  If an indemnifying party is given prompt notice, but fails or
           declines to assume the defense of any such claim or action within
           fifteen (15) days after notice thereof, the indemnified party may
           assume the defense of such claim or action for the account and at the
           risk of the indemnifying party, and any liabilities related thereto
           shall be conclusively deemed a liability of the indemnifying party.

     13.6  Except as provided in paragraph 13.5, an indemnifying party will have
           sole control of the defense of the action and of all negotiations for
           its settlement or compromise. An indemnifying party, however is not
           permitted to settle or compromise any claim or action giving rise in
           a manner that imposes any restrictions or obligations on the
           indemnified party, without the indemnified party's prior written
           consent.

     13.7  The indemnification rights of an indemnified party under this
           Agreement are in addition to all other rights which the indemnified
           party may have at law or in equity or otherwise.

     13.8  Nothing in this section 13 shall be construed to prohibit the
           indemnified party, at its own cost and expense, from retaining
           counsel to participate in the claim or action as to which the party
           is indemnified.

     13.9  This section 13 survives any termination or expiration of this
           Agreement.

14.  Term and Termination

     14.1  The Term of this Agreement is from the Effective Date through to the
           expiration date of the last to expire NEN Patent, unless this
           Agreement is earlier terminated pursuant to the provisions of
           paragraph 14.2, 14.3 or 14.4.

     14.2  Orchid and NEN each has the right to terminate this Agreement at any
           time after four (4) years from the Effective Date, without reason or
           cause, upon ninety (90) days prior written notice.

     14.3  Orchid and NEN each have the right to terminate this Agreement for
           cause if the other fails to make any payment due and owing, or
           commits breach of any material provision of this Agreement and fails
           to make such payment or remedy such breach within sixty (60) days
           after receiving written notice of such default or breach.


                                       17
<PAGE>

     14.4  NEN and Orchid each have the right to terminate this Agreement for
           cause if any proceeding is instituted by or against the other seeking
           to adjudicate it bankrupt or insolvent, or seeking liquidation,
           winding up, reorganization, arrangement, adjustment, protection,
           relief or composition of it or its debts under any law relating to
           bankruptcy, insolvency or reorganization or relief of debtors, or
           seeking an entry of an order for relief or the appointment of a
           receiver, trustee or other similar official for it or any substantial
           part of its property or taking any action to authorize any of the
           foregoing or similar actions if the proceeding or order or action is
           not vacated, denied or dismissed within ninety (90) days after the
           other receives written notice of termination from the terminating
           party. All rights and licenses granted under this Agreement are
           deemed to be, for purposes of Section 365(n) of the United States
           Bankruptcy Code, license or rights to "intellectual property" as
           defined by Section 101(56) of the United States Bankruptcy Code. The
           parties agree to relief from the automatic stay provisions under
           Section 362 of the Bankruptcy Code.

     14.5  Termination or expiration of this Agreement does not release Orchid
           or NEN from any obligation theretofore accrued.

15.  Rights After Termination

     15.1  Upon a party giving notice of termination of this Agreement, NEN will
           fill all accepted purchase orders of Orchid, unless cancelled by
           Orchid, and Orchid, its Affiliates and sub-licensees may finish all
           Kits in the process of manufacture, and advertise, promote, market
           and sell such Kits and all Kits in inventory. Orchid shall pay for
           all such outstanding purchase orders filled and shall not submit any
           purchase orders after the date of the notice of termination.

     15.2  This section 15 shall survive termination of this Agreement.

16.  Miscellaneous

     16.1  The relationship of Orchid and NEN under this Agreement is that of
           independent contractors. The provisions of this Agreement will not be
           construed to create between Orchid and NEN the relationship of
           principal and agent, joint venturers, co-partners or any other
           similar relationship, the existence of which is hereby denied by
           Orchid and NEN. Neither party will be liable in any way for any
           engagement, obligation, liability, contract, representation or
           warranty of the other party to or with any third party. Orchid is not
           an agent for NEN and NEN is not an agent for Orchid for any purpose
           and each party has no right or authority to assume or create any
           obligations, express or implied, on behalf or in the name of the
           other party.

     16.2  No waiver of any breach of any provision of this Agreement will
           constitute a waiver of any prior, concurrent or subsequent breach of
           the same or any other provision of this Agreement; and no waiver will
           be effective unless in writing.

           express courier (e.g. Federal Express) and addressed to the receiving

           pursuant to this paragraph 16.3. The effective date of the notice is
           the date of receipt of the hand or courier delivery.

     16.4  In the event that the performance of this Agreement or of an
           obligation hereunder, other than the payment of money, is prevented,
           restricted or interfered with by reason of any cause not within the
           control of the respective party, and which could not by reasonable
           diligence have been avoided by such party, the party so affected,
           upon the giving of prompt notice to the other party, as to the nature
           and probable duration of such event, will be excused from such
           performance to the extent and for the duration of such prevention,
           restriction or interference,

                                       19
<PAGE>

           provided that the party so affected uses its reasonable efforts to
           avoid or remove such cause of non-performance and will fulfill and
           continue performance under this Agreement whenever and to the extent
           such cause or causes are removed. For the purpose of this paragraph,
           but without limiting the generality hereof, the following are not
           within the control of a party: acts of God; acts or omissions of a
           governmental agency or body; compliance with requests,
           recommendations, rules, regulations, or orders of any governmental
           authority or any officer, department, agency, or instrument thereof;
           flood; storm; earthquake; fire; war; insurrection; riot; accidents;
           acts of the public enemy; invasion; disease: quarantine restrictions;
           strike; labor lockout; differences with workmen; embargoes; delays or
           failures in transportation; and acts of a similar nature.

     16.5  The laws of the State of Delaware, without regard to conflicts of
           laws provisions, govern this Agreement.

     16.6  Both NEN and Orchid consent to the personal jurisdiction and venue of
           the United States District Court for the District of Delaware; and
           such court will have exclusive jurisdiction over any dispute between
           the parties arising under this Agreement. NEN and Orchid both further
           consent that any process or notice of motion or other application to
           the Court or Judge thereof may be served by registered or certified
           mail or by personal service, provided a reasonable period of time for
           appearance is allowed.

     16.7  If any provision of this Agreement is held to be invalid, illegal,
           unenforceable or void, such will be without effect on the validity,
           legality and enforceability of the remaining provisions or this
           Agreement as a whole. Both parties will endeavor to replace the
           invalid, illegal, unenforceable or void provision with a valid and
           enforceable one which in its equitable effect is most consistent with
           the prior provision.

     16.8  The section and paragraph headings and numbering are for convenience
           only and cannot have any effect on the interpretation or construction
           of this Agreement.

     16.9  This Agreement is binding upon and inures to the benefit of the
           heirs, successors and assigns of the parties hereto, provided that
           this Agreement, in whole or in part, is not assignable by either
           party without the prior written consent of the other party, such
           consent not to be unreasonably withheld, except that either party may
           assign this Agreement to any successor by merger or sale of a party
           or of substantially all of its business or assets to which this
           Agreement pertains and Orchid may assign this Agreement to an
           Affiliate of Orchid without any such consent, provided Orchid
           guarantees all performance obligations of Affiliate under this
           Agreement post assignment. Any effort to assign in violation hereof
           is void. In the event of any assignment, the assigning party must
           provide the other party with appropriate documentation of the
           assignment.

     16.10 Each party acknowledges that it has read this Agreement, understands
           it, and agrees to be bound by its terms and further agrees that it
           constitutes the complete

                                       20
<PAGE>

           and exclusive understanding between the parties, which supersedes and
           merges all prior proposals, understandings and all other agreements,
           oral and written, between the parties regarding the subject matter of
           this Agreement, including without limitation the letter from NEN to
           Orchid dated August 19, 1999; and no party has relied on any

                        COMMON STOCK PURCHASE AGREEMENT
                        -------------------------------


     THIS AGREEMENT dated as of February 16, 2000 is by and between ORCHID
BIOSCIENCES, INC. (the "Company"), a Delaware corporation with principal offices
at 303 College Rd. East, Princeton, NJ 08543, USA, and NEN Life Science
Products, Inc. (the "Purchaser"), a Delaware corporation with principal offices
at 549 Albany St., Boston, MA 02118.

     WHEREAS the Company wishes to obtain equity financing and the Purchaser is
willing to purchase and the Company is willing to sell, on the terms and
conditions contained in this Agreement, shares of Common Stock of the Company.

     IN CONSIDERATION of the mutual covenants contained in this Agreement, the
parties agree as follows:

     SECTION 1.  Authorization of Sale of the Shares. The Company has authorized
                 -----------------------------------
the sale to the Purchaser of 125,000 shares (the "Shares") of the Common Stock,
par value per share, of the Company (the "Common Stock") at a purchase price of
$6.00 per share, which price is at a premium to the current fair market value of
the Common Stock.

     SECTION 2.  Sale and Purchase of Shares; Limitations on Transfer; Certain
                 -------------------------------------------------------------
Other Rights.
- ------------

     2.1  Sale and Purchase of Shares.  At the Closing (as defined in Section
          ---------------------------
3), the Company will sell to the Purchaser, and the Purchaser will buy from the
Company, upon the terms and conditions hereinafter set forth, the Shares, at an
aggregate purchase price of $750,000 (the "Purchase Price").

     2.2  Right of First Refusal. If the Purchaser desires to sell all or any
          ----------------------
part of the Shares at any time after the Closing and has received in writing an
irrevocable and unconditional bona fide offer (the "Bona Fide Offer") for the
purchase thereof from a third party (the "Offeror"), the Purchaser shall give
written notice (the "BFO Notice") to the Company setting forth the

                                       26
<PAGE>

Purchaser's desire to sell such Shares, which BFO Notice shall be accompanied by
a photocopy of the original executed Bona Fide Offer and shall set forth at
least the name and address of the Offeror and the price and terms of the Bona
Fide Offer. The Company and/or its designees may elect to purchase some or all
of the Shares to be transferred (the "Offered Shares") upon the terms and
conditions set forth in the BFO Notice by delivering a written notice of such
election to the Purchaser within twenty (20) days after the date of mailing of
the BFO Notice by the Purchaser. The closing of the purchase and sale of the
Offered Shares shall take place on a date agreed upon by the Purchaser and the
Company but in any event within forty-five (45) days after the date of the
mailing of the BFO Notice, at the principal office of the Company, or such other
place as may be agreed to by the Purchaser and the Company. If the Company and
its designees do not elect to purchase all of the Offered Shares, the Purchaser
may transfer and sell any Offered Shares for which such an election is not made
to the Offeror at a price and on terms no more favorable to the Offeror than
those specified in the BFO Notice, provided that such transfer and sale is
consummated during the 60-day period immediately following the date of mailing
of the BFO Notice by the Purchaser. Any Offered Shares not sold or transferred
during such 60-day period will again be subject to the provisions of this
Section 2.2.

     2.3  Restrictions on Offeror.  Any Offeror purchasing all or any portion of
          -----------------------
the  Shares from the Purchaser under Section 2.2 shall be subject to the terms
of this Agreement.

     2.4  Exempted Transfers.  (a) The Purchaser shall be permitted to transfer
          ------------------
the Shares owned by it without complying with the provisions of this Section 2
solely in the event of transfer by the Purchaser to any Affiliate of the
Purchaser (a "Permitted Transferee"), provided that any such Permitted
Transferee shall have delivered to the Company the written agreement of such
Permitted Transferee to be bound by all of the provisions of this Agreement to
the same extent as the Purchaser. For the purposes of this Section, "Affiliate"
shall mean any corporation, firm, partnership or other entity which directly or
indirectly controls or is controlled by or is under common control with a party
to this Agreement. "Control" means ownership, directly or through one or more
affiliates, of fifty percent (50%) or more of the shares of stock entitled to
vote for the election of directors, in the case of a corporation, or fifty
percent (50%) or more of the equity interests in the case of any limited
liability company or other type of legal entity, status as a general partner in
any partnership, or any other arrangement whereby a

                                       27
<PAGE>

party controls or has the right to control the Board of Directors of directors
or equivalent governing body of a corporation or other entity.

          (b)  The rights of the Company under Section 2.2 hereof shall not
apply to any pledge of Shares by the Purchaser which creates a mere security
interest, provided the pledgee provides the Company with a written agreement to
be bound hereby to the same extent as the Purchaser.

     2.5  Failure to Deliver Shares.  If the Purchaser becomes obligated to sell
          -------------------------
any Shares to the Company or its designee under this Section 2 and fails to
deliver such Shares in accordance with the terms of this Agreement, the Company
or its designee may, at its option, in addition to all other remedies it may
have, send to the Purchaser the purchase price for such Shares as is herein
specified. Thereupon, the Company upon written notice to the Purchaser, (i)
shall cancel on its books the certificate or certificates representing the
Shares to be sold and (ii) shall issue, in lieu thereof, in the name of the
Company or its assignee, a new certificate or certificates representing such
Shares, and thereupon all of the Purchaser's rights in and to such Shares shall
terminate.

     2.6  Term.  The provisions of Sections 2.2 through 2.5 shall terminate upon
          ----
the effective date of the registration of the Shares pursuant to the United
States Securities Exchange Act of 1934.

     2.7  Legend.  Each certificate evidencing any of the Shares shall bear a
          ------
legend substantially as follows:

          "The shares represented by this certificate are subject to
          restrictions on transfer and may not be sold, exchanged, transferred,
          pledged, hypothecated, or otherwise disposed of except in accordance
          with and subject to all the terms and conditions of a certain Common
          Stock Purchase Agreement dated as of March __, 2000, a copy of which
          the Company will furnish to the holder of this certificate upon
          request and without charge."

     2.8  Lock-Up.  If, in connection with a registration statement filed by the
          -------
Company pursuant to the Securities Act, the Company or its underwriter so
requests, the Purchaser will agree not to sell any Shares for a period not to
exceed 180 days following the effectiveness of such registration.

                                       28
<PAGE>

     SECTION 3.  Delivery of the Shares at the Closing. The completion of the
                 -------------------------------------
purchase and sale of the Shares being purchased and sold pursuant to this
Agreement (the "Closing") shall occur on a date to be specified by the parties
which shall be no later than March __, 2000, at the offices of Mintz, Levin,
Cohn, Ferris, Glovsky and Popeo, P.C., One Financial Center, Boston,
Massachusetts 02111 (the "Closing Date"). At the Closing, the Purchaser shall
pay to the Company an amount equal to the Purchase Price and the Company shall
deliver to the Purchaser one or more stock certificates representing the Shares
purchased by the Purchaser, each such certificate to be registered in the name
of the Purchaser. The Company's obligation to close the transaction shall be
subject to the following conditions, any of which may be waived by the Company:
(y) receipt by the Company of funds in the full amount of the Purchase Price for
the Shares being purchased hereunder; and (z) the accuracy of the
representations and warranties made by the Purchaser and the fulfillment of
those undertakings of the Purchaser to be fulfilled prior to the Closing. The
Purchaser's obligation to close the transaction shall be subject to the
fulfillment of the following conditions: (a) the execution and delivery by the
Company of the Registration Rights Agreement in the form attached on Exhibit 1
                                                                     ---------
attached hereto (the "Registration Rights Agreement"); (b) the receipt by the
Purchaser of an opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C.,

                                                       ---------
receipt by the Purchaser of a copy of a certificate, dated on or immediately
prior to the Closing Date, as to the good standing of the Company in the state
of Delaware; (d) the receipt by the Purchaser of a stock certificate,
representing the Shares; and (e) the receipt by the Purchaser of a certificate

                                                                   ---------
This Agreement and the Registration Rights Agreement are collectively referred
to herein as the "Transaction Documents".

     SECTION 4.  Representations, Warranties and Covenants of the Company. As
                 --------------------------------------------------------
used herein, "best knowledge" shall mean and include only actual knowledge of
any officers or directors of the Company. The Company hereby represents and
warrants to, and covenants with, the Purchaser as follows:

good standing under the laws of the State of Delaware. The Company has full
corporate power and authority to own, operate and occupy its properties and to
conduct its business as presently conducted and is registered or qualified to do
business and in good standing in each jurisdiction in which it owns or leases
property or transacts business and where the failure to be so qualified would
have a material adverse effect upon the business, financial condition,
properties or operations of the Company. The Company has delivered to the
Purchaser an accurate and complete copy of its Certificate of Incorporation and
all amendments thereto, including without limitation, all Certificates of
Designation filed with the Secretary of State of Delaware.

                 -----------------
power and authority to execute, deliver and perform its obligations under the

and validly executed and delivered by the Company and constitute legal, valid
and binding agreements of the Company enforceable against the Company in
accordance with their terms.

          4.3.   Non-Contravention. The execution and delivery of the
                 -----------------
Transaction Documents, the issuance and sale of the Shares to be sold by the
Company hereunder, the fulfillment of the terms of the Transaction Documents and
the consummation of the transactions contemplated by the Transaction Documents
will not conflict with or constitute a violation of, or default or give rise to
any benefits or an acceleration of any rights of any third party (with the
passage of time or otherwise) under, any material agreement or instrument to
which the Company is a party or by which it is bound or the charter, by-laws or
other organizational documents of the Company nor result in the creation or
imposition of any lien, encumbrance, claim, security interest or restriction
whatsoever upon any of the material properties or assets of the Company or an
acceleration of indebtedness pursuant to any obligation, agreement or condition
contained in any material bond, debenture, note or any other evidence of
indebtedness or any material indenture, mortgage, deed of trust or any other
agreement or instrument to which the Company is a party or by which it is bound
or to which any of the property or assets of the Company is subject, nor
conflict with, or result in a violation of, any law, administrative regulation,
ordinance or order of any court or governmental agency, arbitration panel or
authority applicable to the Company. No consent, approval, authorization or
other order of, or registration, qualification or filing with, any regulatory
body, administrative agency, or other governmental body is required

                                       30

The outstanding shares of capital stock of the Company have been duly and
validly issued and are fully paid and non-assessable.

          4.5  Related-Party Transactions.  Except as disclosed on Schedule 4.5
               --------------------------                          ------------
attached hereto, no employee, officer, or director of the Company or member of
his or her immediate family is indebted to the Company, nor is the Company
indebted (or committed to make loans or extend or guarantee credit) to any of
them.  To the best of the Company's knowledge, none of such persons has any
direct or indirect ownership interest in any firm or corporation with which the
Company is affiliated or with which the Company has a business relationship, or
any firm or corporation that competes with the Company, except that employees,
officers, or directors of the Company and members of their immediate families
may own stock in publicly traded companies that may compete with the Company.
To the best of the Company's knowledge, no officer or director or any member of
their immediate families is, directly or indirectly, interested in any material
contract with the Company.

          4.6  Permits.  The Company has all franchises, permits, licenses, and
               -------
any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could materially and adversely affect the
business, properties, prospects, or financial condition of the Company and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as planned to be conducted.  The Company is not
in default in any material respect under any of such franchises, permits,
licenses or other similar authority.

          4.7  Compliance With Other Instruments.  The Company is not in
               ---------------------------------
violation or default of any provision of its Certificate of Incorporation or
Bylaws or in any material respect of any provision of any mortgage, indenture,
agreement, instrument, or contract to which it is a party or by which it is
bound or, to the best of its knowledge, of any federal or state judgment,

                                       31
<PAGE>

order, writ, decree, statute, rule, or regulation applicable to the Company. The
execution, delivery, and performance by the Company of this Agreement, the
Registration Rights Agreement and the consummation of the transactions
contemplated hereby and thereby will not result in any such violation or be in
material conflict with or constitute, with or without the passage of time or
giving of notice, either a material default under any such provision or an event
that results in the creation of any material lien, charge, or encumbrance upon
any assets of the Company or the suspension, revocation, impairment, forfeiture,
or non-renewal of any material permit, license, authorization, or approval
applicable to the Company, its business or operations, or any of its assets or
properties.

          4.8  Litigation.  There is no action, suit, proceeding, or
               ----------
investigation, to the best of the Company's knowledge, pending or currently
threatened against the Company that questions the validity of this Agreement,
the Registration Rights Agreement or the right of the Company to enter into such
agreements, or to consummate the transactions contemplated hereby or thereby, or
that might result, either individually or in the aggregate, in any material
adverse change in the assets, business, properties, prospects, or financial
condition of the Company, or in any material change in the current equity
ownership of the Company.  The foregoing includes, without limitation, any
action, suit, proceeding, or investigation pending or currently threatened
involving the prior employment of any of the Company's employees, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, their obligations under
any agreements with prior employers, or negotiations by the Company with
potential backers of, or investors in, the Company or its proposed business.
The Company is not a party to, or to the best of its knowledge, named in any
order, writ, injunction, judgment, or decree of any court, government agency, or
instrumentality.  There is no action, suit, or proceeding by the Company
currently pending or that the Company currently intends to initiate.

          4.9  Offering.  Subject in part to the truth and accuracy of the
               --------
Purchaser's representations set forth in Section 5.1 of this Agreement, the
offer, sale and issuance of the Shares as contemplated by this Agreement are
exempt from the registration requirements of the Securities Act, and neither the
Company nor any authorized agent acting on its behalf will take any action
hereafter that would cause the loss of such exemption.

(v) for minor defects in title, none of which, individually or in the aggregate,
materially interferes with the use of such property, the Company owns its
property and assets free and clear of all mortgages, liens, claims, and

in compliance with such leases and, to the best of its knowledge, holds a valid
leasehold interest free of any liens, claims, or encumbrances, subject to
clauses (i)-(v) above.

          4.11 Financial Statements and Preliminary Financial Statements.  The
               ---------------------------------------------------------
Company has delivered to the Purchaser its audited financial statements (balance
sheet and profit and loss statement, statement of stockholders' equity and
statement of cash flows including notes thereto) at December 31, 1998 and 1997
for the fiscal years then ended and shall, within thirty (30) days of the date
hereof, deliver to the Purchaser its audited financial statements for the fiscal
year ending December 31, 1999 and the twelve months ended December 31, 1999 (the
"Financial Statements").  The Financial Statements will have been prepared in
accordance with U.S. Generally Accepted Accounting Principles ("GAAP") applied
on a consistent basis throughout the periods indicated and with each other,
except that unaudited financial statements may not contain all footnotes
required by GAAP.  The Financial Statements will fairly present the financial
condition and operating results of the Company as of the dates, and for the
periods, indicated therein.  Except as set forth in the Financial Statements,
the Company has no material liabilities, contingent or otherwise, other than (i)
liabilities incurred in the ordinary course of business and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under generally accepted accounting principles to be reflected in
the Financial Statements, which, in both cases, individually do not exceed
$125,000, and in the aggregate do not exceed $800,000, other than commitments
set forth on Schedule 4.11 attached hereto.  Except as disclosed in the
             -------------
Financial Statements, the Company is not a guarantor or indemnitor of any
indebtedness of any other person, firm, or corporation.  The Company maintains
and will

                                       33
<PAGE>

continue to maintain a standard system of accounting established and
administered in accordance with GAAP.

          4.12 Changes.  To the best of the Company's knowledge and except as
               -------
set forth in Schedule 4.12 herein or as otherwise permitted by this Agreement,
             -------------
since December 31, 1999, there has not been:

     (a)  any change in the assets, liabilities, financial condition, business
prospects or operating results of the Company from that reflected in the
Financial Statements, except changes in the ordinary course of business that
have not been, in the aggregate, materially adverse;

     (b)  any damage, destruction or loss, whether or not covered by insurance,
materially and adversely affecting the business, properties, prospects, or
financial condition of the Company (as such business is presently conducted and
as it is proposed to be conducted);

     (c)  any material change to a material contract or arrangement by which the
Company or any of its assets is bound or subject;

     (d)  any indebtedness incurred by the Company in excess of $25,000;

     (e)  any change made or authorized to the Company's By-Laws or Charter;

     (f)  any dividends, whether declared, set aside or paid, with respect to
its capital stock (whether in cash or in kind) or redemptions of any such
capital stock;

     (g)  any resignation or termination of employment of any key officer of the
Company; and the Company, to the best of its knowledge, does not know of the
impending resignation of termination of employment of any such officer;

     (h)  receipt of notice that there has been a loss of, or material order
cancellation by, any major customer of the Company;

     (i)  to the best of the Company's knowledge, any other event or condition
of any character that might materially and adversely affect the business,
properties, prospects, or financial condition of the Company (as such business
is presently conducted and as it is proposed to be conducted); or

     (j)  any agreement or commitment, whether written or oral, by the Company
to do any of the things described in this Section 4.12.

          4.13 Patents and Trademarks.  The Company owns or possesses sufficient
               ----------------------
legal rights to all patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses,

                                       34
<PAGE>

information, and proprietary rights and processes presently used by the Company
in its business (the "Intellectual Property Rights"). To the best knowledge of
the Company, the Intellectual Property Rights are the only intellectual property
rights necessary for its business as now conducted and as proposed to be
conducted and, to the best knowledge of the Company, do not conflict with, or
infringe the rights of others. Except for agreements with its own employees or
consultants, there are no outstanding options, licenses, or agreements of any
kind relating to the foregoing, nor is the Company bound by or a party to any
options, licenses, or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information, and proprietary rights and processes of any other person or entity.
The Company has not received any communications alleging that the Company has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights, trade secrets, or
other proprietary rights or processes of any other person or entity. The Company
is not aware that any of its employees is obligated under any contract
(including licenses, covenants, or commitments of any nature) or other
agreement, or subject to any judgment, decree, or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company or that would conflict with the
Company's business as proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as proposed,
will, to the best of the Company's knowledge, conflict with or result in a
breach of the terms, conditions, or provisions of, or constitute a default
under, any contract, covenant, or instrument under which any of such employees
is now obligated.

          4.14 Employees; Employee Compensation.  To the best of the Company's
               --------------------------------
knowledge, there is no strike, or labor dispute or union organization activities
pending or threatened between it and its employees.  None of the Company's
employees belongs to any union or collective bargaining unit.  To the best of
its knowledge, the Company has complied in all material respects with all
applicable state and federal equal opportunity and other laws related to
employment.  To the best of the Company's knowledge, no employee of the Company
is or will be in violation of any judgment, decree, or order, or any term of any
employment contract, patent disclosure agreement, or other contract or agreement
relating to the relationship of any such

                                       35
<PAGE>

employee with the Company, or any other party because of the nature of the
business conducted or to be conducted by the Company or to the use by the
employee of his best efforts with respect to such business. The Company is not
aware that any officer or key employee, or that any group of key employees,
intends to terminate their employment with the Company, nor does the Company
have a present intention to terminate the employment of any of the foregoing.

          4.15 Tax Returns, Payments, and Elections.  The Company has filed all
               ------------------------------------
tax returns and reports as required by all applicable state and Federal laws.
These returns and reports are true and correct in all material respects.  The
Company has paid all taxes and other assessments due, except those contested by
it in good faith; provided that for such contested taxes, the Company has
maintained an adequate reserve.  The provision for taxes of the Company as shown
in the Financial Statements is adequate for taxes due or accrued as of the date
thereof.  The Company has not elected pursuant to the Internal Revenue Code of
1986, as amended ("Code"), to be treated as an S corporation or a collapsible
corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor has
it made any other elections pursuant to the Code (other than elections that
relate solely to methods of accounting, depreciation, or amortization) that
would have a material effect on the business, properties, prospects, or
financial condition of the Company.  The Company has never had any tax
deficiency proposed or assessed against it and has not executed any waiver of
any statute of limitations on the assessments or collection of any tax or
governmental charge.  None of the Company's federal income tax returns and none
of its state income or franchise tax or sales or use tax returns has ever been
audited by governmental authorities.  Since the date of the Financial
Statements, the Company has made adequate provisions on its books of account for
all taxes, assessments, and governmental charges with respect to its business,
properties, and operations for such period.  The Company has withheld or
collected from each payment made to each of its employees, the amount of all
taxes, including, but not limited to, federal income taxes, Federal Insurance
Contribution Act taxes and Federal Unemployment Tax Act taxes required to be
withheld or collected therefrom, and has paid the same to the proper tax
receiving officers or authorized depositories.

          4.16 Insurance.  The Company has in full force and effect fire and
               ---------
casualty insurance policies, with extended coverage, sufficient in amount
(subject to reasonable deductibles) to allow it to replace any of its properties
that might be damaged or destroyed.  The

                                       36
<PAGE>

Company has in full force and effect products liability and errors and omissions
insurance in amounts customary for companies similarly situated.

          4.17 Environmental and Safety Laws. To the best of its knowledge, the
               -----------------------------
Company is not in violation of any applicable statute, law, or regulation
relating to the environment or occupational health and safety (including without
limitation the Federal Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended) and to the best of its knowledge, no material
expenditures are or will be required in order to comply with any such existing
statute, law, or regulation.

          4.18 Disclosure.  The Company has provided the Purchaser with all the
               ----------
information reasonably available to it that the Purchaser has requested for
deciding whether to purchase the Shares.  To the best of the Company's
knowledge, neither this Agreement nor any other written statements or
certificates made or delivered in connection herewith contains any untrue
statement of a material fact or omits to state a material fact necessary to make
the statements herein or therein not misleading.

          SECTION 5.  Representations, Warranties and Covenants of the
                      ------------------------------------------------
Purchaser.
- ---------

          5.1. The Purchaser represents and warrants to, and covenants with, the
Company, as of the date hereof and as of the Closing Date, that: (i) the
Purchaser is an "accredited investor" as defined in Regulation D under the
United States Securities Act of 1933, as amended (the "Securities Act"); and
also is knowledgeable and experienced in making investments in private placement
transactions such as the purchase of the Preferred Shares; (ii) the Purchaser is
knowledgeable, sophisticated and experienced in making, and is qualified to
make, decisions with respect to investments in securities presenting an
investment decision like that involved in the purchase of the Shares, including
investments in securities issued by companies comparable to the Company, and has
requested, received, reviewed and considered all information it deems relevant
in making an informed decision to purchase the Shares; (iii) the Purchaser is
acquiring the Shares set forth above for its own account for investment and with
no present intention of distributing any of such Shares, and no arrangement or
understanding exists with any other person regarding the distribution of any of
such Shares; (iv) the Purchaser will not, directly or indirectly, voluntarily
offer, sell, pledge, transfer or otherwise dispose of (or solicit

                                       37
<PAGE>

any offers to buy, purchase or otherwise acquire or take a pledge of) any of the
Shares except (a) in the event the Shares are registered pursuant to an
effective registration statement under the Securities Act, (b) upon delivery of
an opinion of counsel (which shall be in form and substance reasonably
satisfactory to the Company) that such registration is not required, (c) in
connection with a sale, transfer or other disposition made pursuant to Section
144(k) of the Securities Act or (d) to an Affiliate of the Purchaser provided
that (i) in each of cases (a), (c) and (d) set forth above no opinion of counsel
shall be required and (ii) such offer, sale, pledge or transfer does not
otherwise violate the terms of this Agreement; and (v) the Purchaser has had an
opportunity to ask questions and receive answers from the management of the
Company regarding the Company, its business and the offering of the Shares.

          5.2. The Purchaser further represents and warrants to, and covenants
with, the Company that (i) the Purchaser has full right, power, authority and
capacity to enter into this Agreement and the Registration Rights Agreement and
to consummate the transactions contemplated hereby and has taken all necessary
action to authorize the execution, delivery and performance of this Agreement
and the Registration Rights Agreement, and (ii) upon the execution and delivery
of this Agreement and the Registration Rights Agreement, this Agreement and the
Registration Rights Agreement shall constitute valid and binding obligations of
the Purchaser enforceable in accordance with their terms.

          5.3. The Purchaser acknowledges and understands that there is no
public market for the Shares and that the Purchaser must bear the economic risk
of its investment in the Shares for an indefinite period of time because the
Shares have not been registered under the Securities Act and, therefore, cannot
be sold unless subsequently registered under the Securities Act or an exemption
from such registration is available.  The certificates representing the Shares
issued to Purchaser will bear a legend in substantially the following form:

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT"). SUCH SECURITIES MAY NOT BE OFFERED, SOLD,
          TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF, IN THE
          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR AN
          OPINION OF COUNSEL (WHICH SHALL BE IN FORM AND SUBSTANCE REASONABLY
          SATISFACTORY TO THE COMPANY), THAT SUCH

                                       38
<PAGE>

          REGISTRATION IS NOT REQUIRED, UNLESS SUCH SALE, TRANSFER OR OTHER
          DISPOSITION IS MADE PURSUANT TO RULE 144(K) OF THE SECURITIES ACT, IN
          WHICH CASE SUCH SALE, TRANSFER OR OTHER DISPOSITION MAY BE MADE AND NO
          OPINION OF COUNSEL SHALL BE REQUIRED.

The Company agrees to remove such legend from the certificates representing the
Shares issued to Purchaser at such time as such Shares may be legally sold under
Rule 144 of the Securities Act (or any successor rule) without registration
under the Securities Act, at the request of the Purchaser and upon receipt from
the Purchaser of an opinion, which shall be in form and substance reasonably
satisfactory to the Company, that such legend may be removed.

     The Purchaser agrees that any sale, transfer, pledge, hypothecation or
other disposition of the  Shares shall be made in compliance with such legend
and the requirements set forth in Section 2.2.

     SECTION 6.  Survival of Representations, Warranties and Agreements.
                 ------------------------------------------------------

OTHER DISPOSITION IS MADE PURSUANT TO RULE 144 OF THE SECURITIES ACT, IN WHICH

<PAGE>

COMPANY OR MAY BE AVAILABLE UPON REQUEST.

     (c)  The Company shall be obligated to reissue promptly unlegended
Registrable Securities at the request of any Holder thereof if the Holder shall
have obtained an opinion of counsel (which counsel may be counsel to the
Company) reasonably acceptable to the Company to the effect that the Registrable
Securities proposed to be disposed of may lawfully be so disposed of without
registration, qualification or legend.

     (d)  Any legend endorsed on any Registrable Securities pursuant to
applicable state securities laws and any stop-transfer instructions with respect
to any Registrable Securities shall be removed upon receipt by the Company of an
order of the appropriate blue sky authority authorizing such removal.

1.3  REGISTRATION ON FORM S-3
     ------------------------

     (a)  After the effective date of the Company's initial public offering (the
"Offering Effective Date"), the Company shall use its best efforts to qualify
for registration on Form S-3 or any comparable or successor form or forms.
After the Company has qualified for the use of Form S-3, the Holder of
Registrable Securities shall have the right, at any time on or after the first
anniversary of the Offering Effective Date, to request registrations on Form S-3
(such request shall be in writing and shall state the number of shares of
Registrable Securities to be disposed of and the intended methods of disposition
of such shares by such Holder); provided, however, that the Company shall not be
                                --------  -------
obligated to effect any such registration if (i) the Holder, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) on Form S-3 at an aggregate price to the public of less than
$1,000,000; (ii) in a given twelve-month period, the Company has effected two
(2) such registrations, (iii) it is to be effected more than five (5) years
after the Offering Effective Date; or (iv) the Company shall have furnished to
such Holder a certificate signed by the President of the Company stating that in
good faith judgment of the Board of Directors of the Company, it would be
materially detrimental to the Company for such registration statement to be
filed in the near future and that it has, therefore, determined to defer the
filing of such registration statement, in which case the Company shall have the
right to defer such filing for a period of not more than one hundred eighty
(180) days after receipt of the request of the Holder, and, provided ,further,
                                                            --------  -------
that the Company shall not defer its obligation in this manner more than once in
any twelve-month period.

     (b)  The Company shall not be obligated to effect, or to take any action to
effect, any such registration pursuant to this Section 1.3:

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

                                       48
<PAGE>

               (ii)  After the Company has initiated two (2) such registrations
          for the Holder pursuant to this Section 1.3 (counting for these
          purposes only registrations which have been declared or ordered
          effective and pursuant to which securities have been sold and
          registrations which have been withdrawn by the Holder as to which the
          Holder has not elected to bear the Registration Expenses pursuant to
          Section 1.3(d) hereof and would, absent such election, have been
          required to bear such expenses);

               (iii) During the period starting with the date sixty (60) days
          prior to the Company's good faith estimate of the date of filing of
          and ending on a date one hundred eighty (180) days after the effective
          date of, a Company-initiated registration, including a demand
          registration initiated by the Company on behalf of any holder of
          demand registration rights; provided that the Company is actively
          employing in good faith all reasonable efforts to cause such
          registration statement to become effective.

     (c)  Subject to the foregoing, upon delivery by the Holder of the notice
described in Section 1.3(a) above, the Company shall (i) promptly give written
notice of the proposed registration to all other Holders (if any) and (ii) as
soon as practicable, use its best efforts to effect such registration
(including, without limitation, filing post-effective amendments, appropriate
qualifications under applicable blue sky or other state securities laws and
appropriate compliance with the Securities Act) as would permit or facilitate
the sale and distribution of all or such portion of such Registrable Securities
as are specified in such request, together with all or such portion of the
Registrable Securities of any other Holder joining in such request as are
specified in a written request received by the Company within twenty (20) days
after such written notice from the Company is mailed or delivered. The
registration statement filed pursuant to the request of the Holder may, subject
to the provisions of Sections 1.3(b) and 1.10 hereof, include other securities
of the Company with respect to which registration rights have been granted, and
may include securities of the Company being sold for the account of the Company.

     (d)  All Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 1.3 hereof shall
be borne by the Company.

     (e)  If the registration requested pursuant to Section 1.3 is underwritten,
the rights of the Holder to registration pursuant to Section 1.3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder may elect to include in such underwriting all
or a part of its Registrable Securities. Notwithstanding the foregoing, the
Company shall not be obligated to register the Registrable Securities of any
Holder who fails promptly to provide to the Company such information as the
Company may reasonably request at the time to enable the Company to comply with
applicable laws or regulations or to facilitate preparation of the registration
statement.

     (f)  If the Company shall request inclusion in any registration pursuant to
Section 1.3

                                       49
<PAGE>

of securities being sold for its own account, or if other persons shall request
inclusion in any registration pursuant to Section 1.3, the Holder shall offer to
include such securities in the underwriting and may condition such offer on
their acceptance of the further applicable provisions of this Section 1
(including Section 1.10). The Company shall (together with the Holder and other
persons proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the representative
of the underwriter or underwriters. Notwithstanding any other provision of this
Section 1.3, if the representative of the underwriters advises the Holder in
writing that marketing factors require a limitation on the number of shares to
be underwritten, the number of shares to be included in the underwriting or
registration shall be allocated as set forth in Section 1.10 hereof. If a person
who has requested inclusion in such registration as provided above does not
agree to the terms of any such underwriting, such person shall be excluded
therefrom by written notice from the Company, the underwriter or the Holder. Any
Registrable Securities or other securities excluded shall also be withdrawn from
such registration. If shares are so withdrawn from the registration and if the
number of shares to be included in such registration was previously reduced as a
result of marketing factors pursuant to this Section 1.3(f), then the Company
shall offer to all persons who have retained rights to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among such persons requesting additional inclusion in accordance
with Section 1.10.

1.4  Registration Procedures
     -----------------------

     In the case of each registration effected by the Company pursuant to
Section 1.3, the Company will keep each Holder advised in writing as to the
initiation of each registration and as to the completion thereof. At its
expense, the Company will use its best efforts to:

     (a)  Keep such registration effective for a period of one hundred twenty
(120) days or until the Holder has completed the distribution described in the
registration statement relating thereto, whichever first occurs; provided,
                                                                 --------
however, that such 120-day period shall be extended, if necessary, to keep the
- -------
registration statement effective until all such Registrable Securities are sold,
provided that Rule 145, or any successor rule under the Securities Act, permits
an offering on a continuous or delayed basis, and provided further that
applicable rules under the Securities Act governing the obligation to file a
post-effective amendment permit, in lieu of filing a post-effective amendment
that (I) includes any prospectus required by Section 10(a)(3) of the Securities
Act or (II) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the Exchange Act in the registration statement;

     (b)  Prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement;

                                       50
<PAGE>

     (c)  Furnish such number of prospectuses and other documents incident
thereto, including any amendment of or supplement to the prospectus, as the
Holder from time to time may reasonably request;

     (d)  Notify each seller of Registrable Securities covered by 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
as a result of which the prospectus included in such registration statement as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such seller prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that as thereafter delivered
to the purchasers of such shares such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading or
incomplete in the light of the circumstances then existing;

     (e)  Cause all such Registrable Securities registered pursuant hereunder to
be listed on each securities exchange on which similar securities issued by the
Company are then listed;

     (f)  Provide a transfer agent and registrar for all Registrable Securities
registered pursuant to such registration statement and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration; and

     (g)  Otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable an earnings statement covering the period of at
least twelve months, but not more than eighteen months, beginning with the first
month after the effective date of the Registration Statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act.

1.5  Indemnification
     ---------------

     (a)  The Company will indemnify each Holder, each of its officers,
directors and partners, legal counsel and accountants and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification, or compliance has been
effected pursuant to this Section 1, and each underwriter, if any, and each
person who controls within the meaning of Section 15 of the Securities Act any
underwriter, against all expenses, claims, losses, damages, and liabilities (or
actions, proceedings, or settlements in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus, offering circular, or other document (including any
related registration statement, notification, or the like) incident to any such
registration, qualification, or compliance or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or any rule or regulation

                                       51
<PAGE>

thereunder applicable to the Company and relating to action or inaction required
of the Company in connection with any such registration, qualification, or
compliance, and will reimburse each such Holder, each of its officers,
directors, partners, legal counsel, and accountants and each person controlling
such Holder, each such underwriter, and each person who controls any such
underwriter for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by such Holder or underwriter specifically
for use in the preparation thereof. It is agreed that the indemnity agreement
contained in this Section 1.5(a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability or action if such settlement is
effected without the consent of the Company (which consent shall not be
unreasonably withheld).

     (b)  Each Holder will, if Registrable Securities held by him are included
in the securities as to which such registration, qualification, or compliance is
being effected, indemnify the Company, each of its directors, officers, legal
counsel, and accountants and each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter within the meaning of Section 15 of the
Securities Act, each other such Holder, and each of their officers, directors,
and partners, and each person controlling such Holder, against all expenses,
claims, losses, damages and liabilities (or actions, proceedings, or settlements
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular, or other document (including any related registration statement,
notification, or the like) incident to any such registration, qualification, or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse the Company and such Holder,
directors, officers, partners, legal counsel, and accountants, persons,
underwriters, or control persons for any legal or any other expenses reasonably
incurred in connection with investigating and defending or settling any such
claim, loss, damage, liability, or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by such Holder
specifically for use in the preparation thereof; provided, however, that the
obligations of such Holder hereunder shall not apply to amounts paid in
settlement of any such claims, losses, damages, or liabilities (or actions in
respect thereof) if such settlement is effected without the consent of such
Holder (which consent shall not be unreasonably withheld); and provided that in
no event shall any indemnity under this Section 1.5 exceed the gross proceeds
from the offering received by such Holder.

     (c)  Each party entitled to indemnification under this Section 1.5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of such

                                       52
<PAGE>

claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and the Indemnified Party
may participate in such defense at such party's expense, and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
1.5 to the extent such failure is not prejudicial. No Indemnifying Party in the
defense of any such claim or litigation shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof, the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation and no Indemnified Party shall consent to
entry of any judgment or settle such claim or litigation without the prior
written consent of the Indemnifying Party. Each Indemnified Party shall furnish
such information regarding itself or the claim in question as an Indemnifying
Party may reasonably request in writing and as shall be reasonably required in
connection with defense of such claim and litigation resulting therefrom.

     (d)  If the indemnification provided for in this Section 1.5 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu to indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense, as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

     (e)  Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

1.6  Information by Holder
     ---------------------

     Each Holder of Registrable Securities shall furnish to the Company such
information regarding such Holder and the distribution proposed by such Holder
as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification, or compliance
referred to in this Section 1, except to the extent that the furnishing of such
information would violate any law or any contractual arrangement.  The Company
shall not be obligated to register the Registrable Securities of any Holder who
fails promptly to provide to the Company such information as the Company may
reasonably request

                                       53
<PAGE>

at the time to enable the Company to comply with applicable laws or regulations
or to facilitate preparation of the registration statement, including any
information that the Holder fails to provide on the basis that such information
would violate any law or any contractual arrangement.

1.7  Rule 144 Reporting
     ------------------

     With a view to making available the benefits of certain rules and
regulations of the Commission that may permit the sale of the Restricted
Securities to the public without registration, the Company agrees to use its
best efforts to:

     (a)  Make and keep public information regarding the Company available as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times from and after ninety (90) days following the effective date of the
first registration under the Securities Act filed by the Company for an offering
of its securities to the general public;

     (b)  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
at any time after it has become subject to such reporting requirements;

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

1.8  Transfer or Assignment of Registration Rights
     ---------------------------------------------

     The rights to cause the Company to register securities granted to a Holder
by the Company under this Section 1 may be transferred or assigned by a Holder
only to a transferee or assignee of not less than 50,000 shares of Registrable
Securities (as presently constituted and subject to subsequent adjustments for
stock splits, stock dividends, reverse stock splits, and the like), provided
that the Company is given written notice at the time of said transfer or
assignment stating the name and address of the transferee or assignee and
identifying the securities with respect to which such registration rights are
being transferred or assigned, and, provided further, that the transferee or
assignee of such rights assumes the obligations of such Holder under this
Section 1 and prior to such transfer, as a condition thereof, delivers to the
Company a written instrument by which such transferee agrees to be bound by this
Agreement.

1.9  "Market Stand-Off" Agreement
      ---------------------------

                                       54
<PAGE>

     If requested by the Company and an underwriter of Common Stock (or other
securities) of the Company, a stockholder shall not sell or otherwise transfer
or dispose of any Common Stock (or other securities) of the Company held by such
stockholder (other than those included in the registration) during the one
hundred eighty (180) day period following the effective date of a registration
statement of the Company filed under the Securities Act, provided that:

     (a)  if the stockholder is not an "affiliate" (as defined under Rule 144)
of the Company nor does it hold beneficially or of record 10% or more of the
outstanding equity securities of the Company at the time a registration
statement is filed, then such agreement shall only apply to the first such
registration statement of the Company including, without limitation, the
Company's initial public offering, including securities to be sold on its behalf
to the public in an underwritten offering; and

     (b)  all officers and directors of the Company enter into similar
agreements.

     The obligations described in this Section 1.9 shall not apply to a
registration relating solely to employee benefit plans on Form S-8 or similar
forms that may be promulgated in the future, or a registration relating solely
to a Commission Rule 145 transaction on Form S-4 or similar forms that may be
promulgated in the future. The Company may impose stop-transfer instructions
with respect to the shares (or securities) subject to the foregoing restriction
until the end of said one hundred eighty (180) day period.

1.10 Allocation of Registration Opportunities
     ----------------------------------------

     In any circumstance in which all of the Registrable Securities and other
shares of Common Stock of the Company (including shares of Common Stock issued
or issuable upon conversion of share of any currently unissued series of
Preferred Stock of the Company) with registration rights (the "Other Shares")
requested to be included in a registration on behalf of the Holder or other
selling stockholders cannot be so included as a result of limitations of the
aggregate number of shares of Registrable Securities and Other Shares that may
be so included, the number of shares of Registrable Securities and Other Shares
that may be so included shall be allocated among the Holders and the other
selling stockholders requesting inclusion of shares pro rata on the basis of the
number of shares of Registrable Securities and Other Shares held by such Holders
and other selling stockholders, assuming conversion, that such Holders and
selling stockholders had requested to be included in the registration.

1.11 Delay of Registration Opportunities
     -----------------------------------

     No Holder shall have any right to take any action to restrain, enjoin, or
otherwise delay any registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Section 1.

1.12 Termination of Registration Rights
     ----------------------------------

                                       55
<PAGE>

     The right of any Holder to request registration or inclusion in any
registration pursuant to Section 1.3 shall terminate on such date after the
Offering Effective Date as all shares of Registrable Securities held or entitled
to be held upon conversion by such Holder may immediately be sold under Rule 144
during any ninety (90) day period.

2.   MISCELLANEOUS

2.1  Governing Law
     -------------

     This Agreement shall be governed in all respects by the laws of the State
of New Jersey, as if entered into by and between New Jersey residents
exclusively for performance entirely within New Jersey, and excluding that body
of laws pertaining to conflicts of laws.

2.2  Successors and Assigns
     ----------------------

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

2.3  Entire Agreement; Amendment: Waiver
     -----------------------------------

     This Agreement (including the Exhibits hereto) constitutes the full and
entire understanding and agreement between the parties with regard to the
subjects hereof and thereof. This Agreement supersedes any and all prior
understandings as to the subject matter of this Agreement.  Neither this
Agreement nor any term hereof may be amended, waived, discharged or terminated,
except by a written instrument signed by the Company and the Holders of at least
fifty percent (50%) of the Registrable Securities.  Any such amendment, waiver,
discharge or termination shall be binding on all the Holders, but in no event
shall the obligation of any Holder hereunder be materially increased, except
upon the written consent of such Holder.

2.4  Notices, etc.
     -------------

     All notices and other communications required or permitted hereunder shall
be in writing and shall be mailed by United States first-class mail, postage
prepaid, or delivered personally by hand or nationally recognized courier
addressed (a) if to the Stockholder, at the address set forth on the first page
of this Agreement, or at such other address as such holder or permitted assignee
shall have furnished to the Company in writing, or (b) if to the Company, at 303
College Road East, Princeton, New Jersey 08540, or at such other address as the
Company shall have furnished to each holder in writing. All such notices and
other written communications shall be effective on the date of mailing or
delivery.

2.5  Delays or Omissions
     -------------------

     No delay or omission to exercise any right, power or remedy accruing to any
Holder,

                                       56
<PAGE>

upon any breach or default of the Company under this Agreement shall impair any
such right, power or remedy of such Holder nor shall it be construed to be a
waiver of any such breach or default, or an acquiescence therein, or of or in
any similar breach or default thereafter occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
therefore or thereafter occurring. Any waiver, permit, consent or approval of
any kind or character on the part of any Holder of any breach or default under
this Agreement or any waiver on the part of any Holder of any provisions or
conditions of this Agreement must be made in writing and shall be effective only
to the extent specifically set forth in such writing. All remedies, either under
this Agreement or by law or otherwise afforded to any Holder, shall be
cumulative and not alternative.

2.6  Rights; Separability
     --------------------

     Unless otherwise expressly provided herein, a Holder's rights hereunder are
several rights, not rights jointly held with any of the other Holders. In case
any provision of the Agreement shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

2.7  Confidential Information
     ------------------------

     Each Holder acknowledges that the information received by them pursuant
hereto may be confidential and for its use only, and it will not use such
confidential information in violation of the Exchange Act or reproduce, disclose
or disseminate such information to any other person (other than its employees or
agents having a need to know the contents of such information, and its
attorneys), except in connection with the exercise of rights under this
Agreement, unless the Company has made such information available to the public
generally or such Holder is required to disclose such information by a
governmental body.

2.8  Titles and Subtitles

     The titles of the paragraphs and subparagraphs of this Agreement are for
convenience of reference only and are not to be considered in construing this
Agreement.

2.9  Counterparts
     ------------

     This Agreement may be executed in any number of counterparts, each of which
shall be an original, but all of which together shall constitute one instrument.
