Prospectus summary

This summary highlights information contained elsewhere in this prospectus. You
should read the entire prospectus carefully, especially the risks of investing
in our common stock discussed under "Risk factors." Our principal executive
offices are located at 11555 Sorrento Valley Road, San Diego, CA 92121. Our
telephone number is (858) 350-0345. Our web site is http://www.sequenom.com. We
do not intend the information found on our web site to be a part of this
prospectus.

OUR BUSINESS

We are a pioneer in the new field of industrial genomics. Industrial genomics
is the large scale commercial use of the knowledge of DNA variations for
improving health, agriculture and livestock. These variations are the origin of
most differences between individuals, including disease predispositions and
variations in drug responses. Single nucleotide polymorphisms, or SNPs, are the
most common variations. SNPs represent the smallest possible genetic change,
and occur where the DNA molecules of different persons vary at a single
location. We believe that SNP analysis will play an essential role in the
development of drugs, diagnostics and other life science applications in the
immediate future. Our goal is to be the leader in the commercialization of
industrial-scale SNP analysis.

We have developed the MassArray system, a highly accurate, cost-effective
technology that is capable of high throughput SNP analysis at high speeds. Our
strategy is to capitalize on the quickly emerging demand for SNP analysis in
the areas of drug discovery and development, DNA diagnostics, patient
stratification by genetic traits, clinical trials, seed development and
livestock breeding. Six centers, including several academic and governmental
sites, diagnostic laboratories and a leading biotechnology company, are using
our MassArray system, assessing its performance in the field, and providing us
with information regarding its performance.

THE SNP ANALYSIS MARKET

The SNP analysis market represents a significant portion of both the biochip,
or miniaturized chips containing DNA or other substances, and the DNA
sequencing markets and can be divided into three segments:

 . confirmation of new sites of genetic variation in DNA, which typically
  requires the analysis of a SNP in up to a hundred people;

 . determination of the medical importance of SNPs, which typically requires the
  analysis of a SNP in a few thousand diseased and healthy people; and

 . utilization of SNPs in genomics-based drug development, disease
  predisposition determination and diagnostic test development, which could
  eventually require the analysis of multiple SNPs in millions of people.

Current methods of SNP analysis are inaccurate, non-automated, inflexible,
expensive or slow and are therefore primarily effective only as research tools.
To compensate for deficiencies in accuracy, current methods require either
repetitive testing of each sample or the use of a larger test population, which
makes current methods impractical for most commercial applications.

OUR SOLUTION

Our MassArray system directly analyzes SNPs by improving on a technology called
mass spectrometry. By using mass spectrometry to measure molecular weight, our
MassArray system is capable of characterizing molecules with a high level of
accuracy. This is done at a competitive price and in a single reading. Our
technology is also extremely versatile and can be rapidly reconfigured for
different types of analyses. In addition, the MassArray system is capable of
reading up to 20,000 SNPs per day, which we believe is a throughput that can
meet commercial needs.

                                                                               3
<PAGE>


Our MassArray system has three components--hardware, software and disposables.
The hardware components include a mass spectrometer and liquid dispensing
units, which are off-the-shelf instruments modified to accommodate our
MassArray technology. Our proprietary Genolyzer bioinformatics software
automatically calculates, records, compares and reports genotypes at a rate of
three seconds per sample. Our disposables consist of MassArray kits for SNP
sample preparation, including the proprietary SpectroCHIP on which we place
samples in a 96 spot array for reading by the mass spectrometer.

COMMERCIALIZATION PLAN

We are seeking to penetrate the SNP analysis market by identifying areas of
potential widespread interest and establishing commercial relationships with
opinion leaders. We have initiated this effort by selecting six highly visible
academic, government and commercial centers as collaborators to validate our
MassArray system in pre-launch testing. These centers are Genzyme Corporation,
the US Department of Agriculture, the National Institutes of Health, the
National Cancer Institute, the University of Munster and GLE Medicon in
Germany. In October 1999, we contracted for the first sale of a MassArray
system. We commenced a commercial launch of our MassArray system during the
fourth quarter of 1999.

We intend to develop proprietary disposable SNP tests, called assays, and
software products that are useful initially as research tools to confirm the
association of particular SNPs with particular diseases and subsequently as
diagnostic kits that can be sold for SNP profiling. In addition, we will seek
to retain commercial rights to assays that we develop on behalf of or together
with our customers. Over time, with our customers, we intend to develop
knowledge-based genomic products that combine pharmaceutical, medical and
genetic information, such as validated SNP sets for specific diseases. Also, in
addition to DNA, we believe our MassArray technology can serve as a platform
for the analysis of many other biomolecules. We therefore intend to develop new
products for applications other than DNA and SNP analysis.

Risk factors

You should carefully consider the risks described below together with all of
the other information included in this prospectus before making an investment
decision. If any of the following risks actually occurs, our business,
financial condition or results of operations could be harmed. In that case,
the trading price of our common stock could decline, and you may lose all or
part of your investment.

RISKS RELATED TO OUR BUSINESS

WE ARE AT AN EARLY STAGE OF DEVELOPMENT AND MAY NOT SUCCEED OR BECOME
PROFITABLE.

We commenced operations in 1994 and are at an early stage of development. We
have incurred significant losses to date and our revenues have been limited to
grants from governmental bodies. Our initial products are in testing at a
number of sites and will not be commercially launched until late 1999. As a
result, our business is subject to all of the risks inherent in the
development of a new business enterprise, such as the need:

 . to obtain substantial capital to support the expenses of developing our
  technology and commercializing our products;

 . to develop a market for our products;

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

 . to attract and retain qualified management, sales, technical and scientific
  staff.

Our operations also may be affected by problems frequently encountered with
the use of new technologies and by the competitive environment in which we
operate, as well as the risks detailed below.

IF WE INCUR LOSSES IN THE FUTURE, AS WE EXPECT TO DO, THE VALUE OF OUR STOCK
COULD DECREASE.

Since inception, we have recognized no revenue from product sales. Our
expenses have exceeded revenue in each of the years since our inception. It is
uncertain when, if ever, we will become profitable. As of September 30, 1999,
our accumulated deficit was $37.1 million. Our expenses have consisted
principally research and development and of general and administrative
expenses incurred while building our business infrastructure. We expect to
continue to experience significant operating losses in the future as we
continue our research and development efforts, further develop our
manufacturing capabilities and expand our marketing and sales force in an
effort to commercialize our products. Our net operating loss and credit
carryforwards may be limited due to a cumulative change in ownership of more
than 50%, which occurred during 1998 and which is anticipated to occur with
the offering.

IF WE ARE UNABLE TO OBTAIN ADDITIONAL FUNDS, AS WE EXPECT, WE WOULD HAVE TO
REDUCE OR CEASE OPERATIONS, ATTEMPT TO SELL SOME OR ALL OF OUR OPERATIONS OR
MERGE WITH ANOTHER ENTITY.

Based on our current plans, we believe our existing cash, cash equivalents and
short-term investments, together with the net proceeds of this offering will
be sufficient to fund our operating expenses, debt obligations and capital
requirements through at least the next 24 months. However, the actual amount
of funds that we will need during or after the next 24 months will be
determined by many factors, some of which are beyond our control, and we may
need funds sooner than currently anticipated. These factors include:

 . the level of our success in selling our MassArray system and associated
  technologies;

- -------------------------------------------------------------------------------
                                                                              7
<PAGE>

RISK FACTORS

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

 . our progress with research and development;

 . our ability to introduce and sell new products;

 . the level of our sales and marketing expenses;

 . the level of our expenses associated with unforeseen litigation;

 . the costs and timing of obtaining new patent rights; and

 . regulatory changes and competition and technological developments in the
  market.

If additional funds are required and we are unable to obtain them on terms
favorable to us, we may be required to cease or reduce further
commercialization of our products, to sell some or all of our technology or
assets or to merge with another entity. If we raise additional funds by
selling additional shares of our capital stock, the ownership interest of our
stockholders will be diluted.

WE MUST DEVELOP AND COMMERCIALIZE OUR NEXT GENERATION PRODUCTS AT REDUCED
COSTS FOR US TO BE PROFITABLE.

Our current products do not provide sufficient gross margin for us to become
profitable. We intend to develop and manufacture our next generation products
at a lower cost than the cost of our current products. We may not be
successful in doing so. In addition, our gross margin and profitability may be
negatively impacted if we are unable to achieve market acceptance or
appropriate pricing for our next generation products.

WE MAY NOT BE ABLE TO SUCCESSFULLY ADAPT OUR PRODUCTS FOR COMMERCIAL
APPLICATIONS.

We have completed the initial development of our MassArray technology for
applications in the genetic aspects of drug development and life science
research. We may not be able to successfully adapt our products to the
commercial requirements of these fields. A number of potential applications of
our technology in these fields will require significant enhancements in our
core technology, including adaptation of our software and further
miniaturization. In addition, we need to enhance our population-based DNA
bank, establish databases for determining the medical importance of SNPs and
rapidly design assays for SNP analysis in sufficient quantity to meet the high
throughput that we expect our future customers will require. If we are unable,
for technological or other reasons, to complete the development, introduction
or scale-up of the manufacturing of any product, or if any product does not
achieve a significant level of market acceptance, our business, financial
condition and results of operations could be seriously harmed. Market
acceptance will depend on many factors, including demonstrating to customers
that our technology is superior to other technologies and products which are
available now or which may become available in the future. We believe that our
revenue growth and profitability will substantially depend on our ability to
overcome significant technological challenges and successfully introduce our
products into the marketplace.

OUR SYSTEM AND RELATED DISPOSABLE SALES MAY BE LIMITED IF OUR MASSARRAY SYSTEM
IS USED BELOW ITS CAPACITY AS A RESULT OF THE SPEED OF SAMPLE PREPARATION AND
THE NEED FOR ASSAY DESIGN.

The need to design a unique assay for each newly discovered SNP can
substantially delay the commencement of the analysis of that SNP. In addition,
the extraction of DNA from biological material is time consuming. MassArray
system users who need to develop assays or who lack sufficient sample
preparation resources therefore may be unable to use our system to its full
capacity. Customers who are unable to use our MassArray system to full
capacity may share MassArray systems, which would result in lower system
sales. Therefore, customers may not purchase sufficient quantities of
disposables for us to become profitable.

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

<PAGE>

RISK FACTORS

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

WE DEPEND ON OUR CUSTOMERS TO PURCHASE SUFFICIENT QUANTITIES OF SPECTROCHIPS
AND OTHER DISPOSABLES FOR US TO BE PROFITABLE.

Our customers may not generate sufficient throughput using our MassArray
system. This may limit their purchases of SpectroCHIPs and other disposables.
Factors which may limit the use of SpectroCHIPs and other disposables include:
the acceptance of our technology by our customers, the ability to analyze more
than one SNP simultaneously on a single spot and the training of customer
personnel. If our customers are slow to, or never, achieve sufficient
throughput, we may never achieve profitability.

IF OUR CUSTOMERS ARE UNABLE TO ADEQUATELY PREPARE SAMPLES AS REQUIRED BY OUR
SYSTEM, THE OVERALL MARKET DEMAND FOR OUR PRODUCTS MAY DECLINE.

Before using our MassArray system, customers must prepare samples by following
several steps that are prone to human error, including DNA isolation and DNA
segment amplification. If DNA samples are not prepared appropriately, our
MassArray system will not generate a reading. If our customers experience
similar difficulties, they may achieve lower levels of throughput than those
for which our system was designed. If our customers are unable to generate
expected levels of throughput, they may not continue to purchase our
disposables, they may express their discontent with our products in the
marketplace, potentially driving down demand for our products, or they may
collaborate with others to jointly use our products. Any or all of these
actions would reduce the overall market demand for our products.

IF ETHICAL AND OTHER CONCERNS SURROUNDING THE USE OF GENETIC INFORMATION BE-
COME WIDESPREAD, WE MAY HAVE LESS DEMAND FOR OUR PRODUCTS.

Genetic testing has raised ethical issues regarding confidentiality and the
appropriate uses of the resulting information. For these reasons, governmental
authorities may call for limits on or regulation of the use of genetic testing
or 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 seriously harm our
business, financial condition and results of operations.

WE DEPEND ON THIRD-PARTY PRODUCTS AND SERVICES AND SOLE OR LIMITED SOURCES OF
SUPPLY TO DEVELOP AND MANUFACTURE SOME COMPONENTS OF OUR PRODUCTS.

We rely to a substantial extent on outside vendors to manufacture many of the
components and subassemblies used in our products. Some of these components
and subassemblies are obtained from a single supplier or a limited group of
suppliers. Our reliance on outside vendors generally, and a sole or a limited
group of suppliers in particular, involves several risks, including:

 . the inability to obtain an adequate supply of required components due to
  manufacturing capacity constraints, a discontinuance of a product by a
  third-party manufacturer or other supply constraints;

 . reduced control over quality and pricing of components; and

 . delays and long lead times in receiving materials from vendors.

WE HAVE LIMITED COMMERCIAL MANUFACTURING CAPABILITY AND EXPERIENCE AND MAY EN-
COUNTER MANUFACTURING PROBLEMS OR DELAYS WHICH COULD RESULT IN LOWER REVENUE.

We have not yet produced our SpectroCHIP in commercial quantities. We may not
be able to maintain acceptable quality standards while producing commercial
quantities. Our customers also require that we comply with current good
manufacturing practices that we may not be able to meet. To achieve the

                                                                              9
<PAGE>

RISK FACTORS

- -------------------------------------------------------------------------------
production levels necessary for successful commercialization of our products,
we will need to scale-up our manufacturing facilities, establish more
automated manufacturing capabilities and maintain adequate levels of
inventory. We may not be able to manufacture sufficient quantities to meet
market demand. If we cannot achieve the required level and quality of
production, we may need to outsource production or rely on licensing and other
arrangements with third parties who possess sufficient manufacturing
facilities and capabilities. This could reduce our gross margins and expose us
to the risks inherent in relying on others. We may not be able to successfully
outsource our production or enter into licensing or other arrangements with
these third parties, which could adversely affect our business.

WE HAVE A LIMITED SALES FORCE AND LIMITED EXPERIENCE IN COMMERCIALIZING OUR
PRODUCTS WHICH MAY CAUSE SIGNIFICANT DIFFICULTIES IN COMMERCIALIZING OUR PROD-
UCTS.

Our direct sales force may not be sufficiently large or knowledgeable to
successfully penetrate the market. We may not be able to expand our direct
sales force to meet our commercial objectives. In addition, our sales force
may not be able to address complex scientific and technical issues raised by
our customers. Our customer support personnel may also lack the broad range of
technical expertise required to adequately service and support our products in
the field.

OUR ABILITY TO COMPETE IN THE MARKET MAY DECLINE IF WE LOSE SOME OF OUR INTEL-
LECTUAL PROPERTY RIGHTS DUE TO BECOMING INVOLVED IN EXPENSIVE LAWSUITS TO PRO-
TECT OR ENFORCE OUR PATENTS.

Our success will depend on our ability to obtain and protect patents on our
technology and to protect our trade secrets. Our patents, which have been or
may be issued, may not afford meaningful protection for our technology and
products. Others may challenge our patents and, as a result, our patents could
be narrowed, invalidated or unenforceable. In addition, our current and future
patent applications may not result in the issue of patents in the United
States or foreign countries. Competitors may develop products similar to ours
that do not conflict with our patents. In addition, others may develop
products for use in the MassArray system in violation of our patents that may
reduce sales of disposables. In order to protect or enforce our patent rights,
we may initiate patent litigation against third parties, such as infringement
suits or interference proceedings. These lawsuits could be expensive, take
significant time and divert management's attention from other business
concerns. We may also provoke these third parties to assert claims against us.
The patent position of biotechnology firms generally is highly uncertain,
involves complex legal and factual questions, and has recently been the
subject of much litigation. No consistent policy has emerged from the US
Patent and Trademark Office or the courts regarding the breadth of claims
allowed or the degree of protection afforded under biotechnology patents. In
addition, there is a substantial backlog of biotechnology patent applications
at the US Patent and Trademark Office, and the approval or rejection of patent
applications may take several years.

THE RIGHTS WE RELY UPON TO PROTECT OUR INTELLECTUAL PROPERTY UNDERLYING OUR
PRODUCTS MAY NOT BE ADEQUATE, WHICH COULD ENABLE THIRD PARTIES TO USE OUR
TECHNOLOGY AND WOULD REDUCE OUR ABILITY TO COMPETE IN THE MARKET.

We require our employees, consultants and advisors to execute confidentiality
agreements. However, we cannot guarantee that these agreements will provide us
with adequate protection against improper use or disclosure of confidential
information. In addition, in some situations, these agreements may conflict
with, or be subject to, the rights of third parties with whom our employees,
consultants or advisors have prior employment or consulting relationships.
Further, others may independently develop substantially equivalent proprietary
information and techniques, or otherwise gain access to our trade secrets.

RISK FACTORS

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

OUR SUCCESS WILL DEPEND PARTLY ON OUR ABILITY TO OPERATE WITHOUT INFRINGING ON
OR MISAPPROPRIATING THE PROPRIETARY RIGHTS OF OTHERS.

We may be sued for infringing on the patent rights of others. Intellectual
property litigation is costly, and, even if we prevail, the cost of such
litigation could adversely affect our business, financial condition and
results of operations. In addition, litigation is time consuming and could
divert management attention and resources away from our business. If we do not
prevail in any litigation, in addition to any damages we might have to pay, we
could be required to stop the infringing activity or obtain a license. Any
required license may not be available to us on acceptable terms, or at all. In
addition, some licenses may be non-exclusive, and therefore, our competitors
may have access to the same technology licensed to us. If we fail to obtain a
required license or are unable to design around a patent, we may be unable to
sell some of our products, which could have a material adverse affect on our
business, financial condition and results of operations. From time to time, we
receive letters from companies regarding their issued patents and patent
applications alleging possible infringement. For example, we have received
correspondence from a company informing us of its recently issued patent
concerning a diagnostic method relying upon a specific manner for comparing
mass spectra, upon which it believes we may be infringing. We do not believe
that we infringe this patent.

IF WE DO NOT SUCCEED IN OBTAINING DEVELOPMENT AND MARKETING RIGHTS FOR SOME OF
THE ASSAYS DEVELOPED IN COLLABORATION WITH OUR CUSTOMERS, OUR REVENUE AND
PROFITABILITY COULD BE REDUCED.

Our business strategy includes the development of assays in collaboration with
customers, and we intend to obtain commercialization rights for those assays.
If we are unable to obtain rights to those assays, our revenue and
profitability could be reduced. To date, we have not initiated significant
activities with respect to the exploitation of any commercialization rights or
products developed in collaboration with third parties. Even if we obtain
commercialization rights, commercialization of products may require resources
that we do not currently possess and may not be able to develop or obtain.

WE MAY BE UNABLE TO OBTAIN LICENSES TO PATENTED SNPS WHICH COULD PREVENT US
FROM OBTAINING SIGNIFICANT REVENUE OR BECOMING PROFITABLE.

The US Patent and Trademark Office has issued at least one patent to a third
party relating to a SNP. If important SNPs are patented, we will need to
obtain rights to those SNPs in order to develop, use and sell related assays.
Required licenses may not be available on commercially acceptable terms, or at
all. If we fail to obtain licenses to important patented SNPs, we may never
achieve significant revenue or become profitable.

BECAUSE OUR PRODUCTS CURRENTLY DEPEND ON COMPONENTS LICENSED FROM THIRD PAR-
TIES, A BREACH BY US OF ANY OF THE TERMS OF THESE LICENSES COULD RESULT IN THE
LOSS OF ACCESS TO THESE COMPONENTS AND COULD DELAY OR SUSPEND OUR COMMERCIAL-
IZATION EFFORTS.

Some aspects of our technology have been acquired or licensed from third
parties. A failure by us to maintain the right to use these components could
seriously harm our business, financial condition and results of operations. In
addition, changes to or termination of our agreements with these third parties
could result in the loss of access to these aspects of our technology and
could delay or suspend our commercialization efforts.

Our grants from the government give the government certain license rights to
inventions resulting from funded work in the event that we fail to
commercialize the technology developed using government funds. Our business
could be harmed if the government exercises those rights.

RISK FACTORS

- -------------------------------------------------------------------------------
OUR ACADEMIC ARRANGEMENTS ARE AN IMPORTANT PART OF OUR BUSINESS AND FAILURE TO
MAINTAIN EXISTING RELATIONSHIPS OR ESTABLISH ADDITIONAL RELATIONSHIPS COULD
ADVERSELY AFFECT OUR RESEARCH AND PRODUCT DEVELOPMENT EFFORTS.

We have relationships with scientists and consultants at academic and other
institutions who conduct research at our request. Our existing relationships
may not be successful. These researchers are not employed by us and may have
commitments to, or consulting or advisory contracts with, other entities that
may limit their availability to work on our projects. As a result, we have
limited control over their activities and, except as otherwise required by our
agreements with these persons, we can expect only limited amounts of their
time to be dedicated to our projects. Our ability to make new discoveries and
to commercialize products based on those discoveries may depend in part on
continued arrangements with researchers at academic and other institutions. We
may not be able to negotiate acceptable arrangements with academic or other
institutions or individuals.

FAILURE TO EXPAND OUR INTERNATIONAL SALES AS WE INTEND WOULD REDUCE OUR ABIL-
ITY TO BECOME PROFITABLE.

We expect that a significant portion of our sales will be made outside the
United States. A successful international effort will require us to develop
relationships with international customers and partners. We may not be able to
identify, attract or retain suitable international customers and partners. As
a result, we may be unsuccessful in our international expansion efforts.
Furthermore, expansion into international markets will require us to continue
to establish and grow foreign operations, hire additional personnel to run
these operations and maintain good relations with our foreign customers and
partners.

International operations involve a number of risks not typically present in
domestic operations, including:

 . currency fluctuation risks;

 . changes in regulatory requirements;

 . costs and risks of deploying systems in foreign countries;

 . licenses, tariffs and other trade barriers;

 . political and economic instability;

 . difficulties in staffing and managing foreign operations;

 . potentially adverse tax consequences; and

 . the burden of complying with a wide variety of complex foreign laws and
  treaties.

Our international operations will also be subject to the risks associated with
the imposition of legislation and regulations relating to the import or export
of high technology products. We cannot predict whether tariffs or restrictions
upon the importation or exportation of our products will be implemented by the
United States or other countries.

WE MAY LOSE MONEY WHEN WE EXCHANGE FOREIGN CURRENCY RECEIVED FROM INTERNA-
TIONAL SALES INTO US DOLLARS.

A significant portion of our business is expected to be conducted in
currencies other than the US dollar. We recognize foreign currency gains or
losses arising from our operations in the period incurred. As a result,
currency fluctuations between the US dollar and the currencies in which we do
business will cause foreign currency translation gains and losses. We cannot
predict the effects of exchange rate fluctuations upon our future operating
results because of the number of currencies involved, the variability of

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

RISK FACTORS

- -------------------------------------------------------------------------------
currency exposure and the potential volatility of currency exchange rates. We
do not currently engage in foreign exchange hedging transactions to manage our
foreign currency exposure.

THE SALES CYCLE FOR OUR PRODUCTS IS LENGTHY. WE MAY EXPEND SUBSTANTIAL FUNDS
AND MANAGEMENT EFFORT WITH NO ASSURANCE OF SUCCESSFULLY SELLING OUR PRODUCTS
OR SERVICES.

Our ability to obtain customers for our products and services depends in
significant part upon the perception that our products and services can help
accelerate efforts in genomics. The sales cycle is typically lengthy. Our
sales effort requires the effective demonstration of the benefits of our
products and services to and significant training of many different
departments within a potential customer. These departments might include
research and development personnel and key management. In addition, we may be
required to negotiate agreements containing terms unique to each customer. We
may expend substantial funds and management effort with no assurance that we
will successfully sell our products or services.

OUR INDUSTRY IS HIGHLY COMPETITIVE AND WE MAY NOT HAVE THE RESOURCES REQUIRED
TO SUCCESSFULLY COMPETE.

The biotechnology industry is highly competitive. We compete with companies in
the United States and abroad that are engaged in the development and
production of products that analyze genetic information. They include:

 . biotechnology, pharmaceutical, chemical and other companies;

 . academic and scientific institutions;

 . governmental agencies; and

 . public and private research organizations.

Many of our competitors have much greater financial, technical, research,
marketing, sales, distribution, service and other resources than we do.
Moreover, our competitors may offer broader product lines and have greater
name recognition than we do, and may offer discounts as a competitive tactic.
In addition, several development stage companies are currently making or
developing products that compete with or will compete with our products. Our
competitors may develop or market technologies or products that are more
effective or commercially attractive than our current or future products, or
that may render our technologies and products obsolete.

WE ARE HIGHLY DEPENDENT ON PRINCIPAL MEMBERS OF OUR MANAGEMENT AND SCIENTIFIC
STAFF, THE LOSS OF WHOM WOULD IMPAIR OUR ABILITY TO COMPETE.

We are highly dependent on the principal members of our management and
scientific staff. The loss of the services of any of these persons could delay
or reduce our product development and commercialization efforts. In addition,
we will require additional personnel in the areas of scientific research,
diagnostic testing, manufacturing and marketing. We may not be able to attract
and retain qualified personnel, which could seriously harm our business,
financial condition and results of operations.

WE MAY NOT HAVE ADEQUATE INSURANCE AND IF WE BECOME SUBJECT TO PRODUCT LIABIL-
ITY CLAIMS, WE MAY EXPERIENCE REDUCED DEMAND FOR OUR PRODUCTS OR BE REQUIRED
TO PAY DAMAGES THAT EXCEED OUR INSURANCE LIMITATIONS.

Our business exposes us to potential product liability claims that are
inherent in the life science field. Any product liability claim in excess of
our insurance coverage would have to be paid out of our cash-

- -------------------------------------------------------------------------------
                                                                             13

RISK FACTORS

- -------------------------------------------------------------------------------
reserves which would have a detrimental effect on our financial condition. It
is difficult to determine whether we have obtained sufficient insurance to
cover potential claims. Also, we cannot assure you that we can or will
maintain our insurance policies on commercially acceptable terms, or at all.

RESPONDING TO CLAIMS RELATING TO IMPROPER HANDLING, STORAGE OR DISPOSAL OF
HAZARDOUS CHEMICALS AND RADIOACTIVE AND BIOLOGICAL MATERIALS WHICH WE USE,
COULD BE TIME CONSUMING AND COSTLY.

We use controlled hazardous and radioactive materials in our business. The
risk of accidental contamination or injury from these materials cannot be
completely eliminated. If an accident with these substances occurs, we could
be liable for any damages that result, which could seriously harm our
business. Additionally, an accident could damage our research and
manufacturing facilities and operations, resulting in delays and increased
costs.

IF OUR MANUFACTURING FACILITY IS DAMAGED, WE COULD EXPERIENCE LOST REVENUE AND
OUR BUSINESS WOULD BE SERIOUSLY HARMED.

Our only manufacturing facility is located in San Diego, California. Damage to
our facility due to fire, natural disaster, power loss, communications
failure, unauthorized entry or other events could cause us to cease
development and manufacturing of our products. We have limited insurance to
protect against business interruption; however, there can be no assurance this
insurance will be adequate or will continue to be available to us on
commercially reasonable terms, or at all.

IF WE OR OUR SUPPLIERS FAIL TO BE YEAR 2000 OR Y2K COMPLIANT IT COULD CAUSE
INTERRUPTIONS IN OUR SUPPLY OF PRODUCTS AND GENERATE SUBSTANTIAL EXPENSES FOR
OUR BUSINESS.

The Y2K issue is a situation that results from computer systems and software
products being coded using two digits rather than four digits to define the
applicable year. Computer systems and software products often utilize embedded
technology that is time-sensitive and may recognize a date falling in the year
2000 as falling in the year 1900 which could cause computer system failures
and errors leading to a disruption of our business operations. The Y2K issue
could affect not only our operations but also the operations of our business
partners, customers and suppliers among others. If we or our suppliers fail to
be Y2K compliant, our business, financial condition and results of operations
could be materially disrupted. Please see "Management's discussion and
analysis of financial condition and results of operations--Impact of the year
2000" for additional information regarding the Y2K issue.

IF WE DO NOT EFFECTIVELY MANAGE OUR GROWTH, IT COULD AFFECT OUR ABILITY TO
PURSUE BUSINESS OPPORTUNITIES AND EXPAND OUR BUSINESS.

Growth in our business has placed, and will continue to place, a significant
strain on our management systems and resources. We will need to continue to
improve our operational and financial systems and managerial controls and
procedures and expand, train and manage our workforce. We will have to
maintain close coordination among our technical, accounting, marketing, sales
and research departments. If we fail to effectively manage our growth and
address the above concerns, it could affect our ability to pursue business
opportunities and expand our business.

RISK FACTORS

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

RISKS RELATED TO THIS OFFERING

CONCENTRATION OF OWNERSHIP OF OUR COMMON STOCK AMONG OUR EXISTING EXECUTIVE
OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS MAY PREVENT NEW INVESTORS FROM
INFLUENCING SIGNIFICANT CORPORATE DECISIONS.

Upon completion of this offering, our executive officers, directors and
beneficial owners of 5% or more of our common stock and their affiliates will,
in aggregate, beneficially own approximately 50.4% of our outstanding common
stock or 48.8% if the underwriters' over-allotment option is exercised in
full. As a result, these persons, acting together, will have the ability to
determine the outcome of all matters submitted to our stockholders for
approval, including the election and removal of directors and any merger,
consolidation or sale of all or substantially all of our assets. In addition,
such persons, acting together, will have the ability to control the management
and affairs of our company. Accordingly, this concentration of ownership may
harm the market price of our common stock by:

 . delaying, deferring or preventing a change in control of our company;

 . impeding a merger, consolidation, takeover or other business combination
  involving our company; or

 . discouraging a potential acquirer from making a tender offer or otherwise
  attempting to obtain control of our company.

Please see "Principal stockholders" for additional information on
concentration of ownership of our common stock.

THERE MAY NOT BE AN ACTIVE, LIQUID TRADING MARKET FOR OUR COMMON STOCK.

We cannot assure you that an active trading market for our common stock will
develop following this offering. You may not be able to sell your shares
quickly or at the market price if trading in our stock is not active. The
initial public offering price will be determined by negotiations between us
and the representatives of the underwriters based upon a number of factors.
The initial public offering price may not be indicative of prices that will
prevail in the trading market. Please see "Underwriting" for more information
regarding our arrangement with the underwriters and the factors considered in
setting the initial public offering price.

OUR STOCK PRICE COULD BE VOLATILE AND YOUR INVESTMENT COULD SUFFER A DECLINE
IN VALUE, WHICH IN TURN COULD AFFECT OUR ABILITY TO RAISE ADDITIONAL CAPITAL
TO FUND THE COMMERCIALIZATION OF OUR PRODUCTS.

The trading price of our common stock is likely to be highly volatile and
could be subject to wide fluctuations in price in response to various factors,
many of which are beyond our control, including:

 . actual or anticipated variations in quarterly operating results;

 . announcements of technological innovations by us or our competitors;

 . new products or services introduced or announced by us or our competitors;

 . changes in financial estimates by securities analysts;

 . conditions or trends in the biotechnology, pharmaceutical and genomics
  industries;

 . changes in the market valuations of other similar companies;

 . announcements by us of significant acquisitions, strategic partnerships,
  joint ventures or capital commitments;

 . additions or departures of key personnel; and

 . sales of our common stock.

RISK FACTORS

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

In addition, the stock market in general, and the Nasdaq National Market and
the market for technology companies in particular, has experienced extreme
price and volume fluctuations that have often been unrelated or
disproportionate to the operating performance of those companies. Further,
there has been particular volatility in the market prices of securities of
biotechnology and life sciences companies. These broad market and industry
factors may seriously harm the market price of our common stock, regardless of
our operating performance. In the past, following periods of volatility in the
market price of a company's securities, securities class-action litigation has
often been instituted against that company. Such litigation, if instituted
against us, could result in substantial costs and a diversion of management's
attention and resources, which could seriously harm our business, financial
condition and results of operations.

WE MAY HAVE TO RETURN THE MONEY WE RECEIVE FROM THE SELLING STOCKHOLDERS AFTER
THEY COMPLETE THE PURCHASE OF APPROXIMATELY 65,000 SHARES BECAUSE OF A
POSSIBLE VIOLATION OF SECTION 5 OF THE SECURITIES ACT OF 1933.

In March 1999, we entered into a consulting agreement with two German
consulting firms for services to be provided to us in connection with our
initial public offering. Under this agreement we offered and committed
ourselves to sell an equivalent of DEM3 million worth of shares, based on our
initial public offering price, to these consulting firms. This equates to
approximately 65,000 shares of our common stock, assuming an initial offering
price of $24.00 per share, or a total of approximately $1.6 million worth of
shares. At the time we offered and committed ourselves to issue these shares,
we did not deliver a preliminary prospectus to these consulting firms. We may
have a contingent liability arising out of a possible violation of Section 5
of the Securities Act of 1933 in connection with the offer and commitment to
sell these shares being made in March 1999. If we violated Section 5 of the
Securities Act of 1933, these consulting firms may have the right to have us
repurchase any shares sold to them at the initial public offering price for up
to one year from the date the consultants discovered any such violation. In no
event could this right extend beyond three years.

THE LARGE NUMBER OF SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD
CAUSE OUR STOCK PRICE TO DECLINE.

Sales of substantial amounts of our common stock in the public market after
this offering could seriously harm prevailing market prices for our common
stock. These sales might make it difficult or impossible for us to sell
additional securities when we need to raise capital. The number of additional
shares available for sale in the public market will be affected by
restrictions imposed by:

 . the Securities Act and related rules, including the volume and other
  restrictions of Rule 144; and

 . lock-up agreements between us and selected stockholders or between
  stockholders and the underwriters.

Please see "Shares eligible for future sale" for a description of the number
of shares which may be sold by existing stockholders in the future.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD MAKE
A THIRD-PARTY ACQUISITION OF US DIFFICULT. THIS COULD LIMIT THE PRICE INVEST-
ORS MIGHT BE WILLING TO PAY IN THE FUTURE FOR OUR COMMON STOCK.

The anti-takeover provisions in our certificate of incorporation, our bylaws
and Delaware law could make it more difficult for a third party to acquire us
without approval of our board of directors. As a result of these provisions,
we could delay, deter or prevent a takeover attempt or third party acquisition
that our stockholders consider to be in their best interests, including a
takeover attempt that results in a premium over the market price for the
shares held by our stockholders. Please see "Description of securities" for
more information on these anti-takeover provisions.

- -------------------------------------------------------------------------------
Use of proceeds

We estimate that the net proceeds from the sale of the 5,000,000 shares of
common stock that we are selling in this offering will be approximately $110.3
million, or approximately $127.0 million if the underwriter's over-allotment
option is exercised in full, based on an assumed initial public offering price
of $24.00 per share and after deducting the underwriting discounts and
commissions and estimated offering expenses payable by us. We will not receive
any proceeds from the sale of shares by the selling stockholders.

We anticipate using the net proceeds from the offering for general corporate
purposes, including hiring additional sales and customer support personnel,
expansion of our facilities, continued development and manufacturing of
existing products, research and development of additional products, expenses
for filing and pursuing patent applications, and working capital. We expect,
if the opportunity arises, to use an unspecified portion of the net proceeds
to acquire or invest in products, technologies or companies. While we
periodically engage in preliminary discussions with respect to acquisitions,
we are not currently a party to any agreements or commitments and have no
understandings with respect to any acquisitions.

We expect to use approximately $3.3 million of the proceeds of this offering
for the repayment of long-term debt and accrued interest owed to TBG. This
debt, which originated in 1995 and 1997, is denominated in German deutsche
marks, DEM, and totals DEM6 million or approximately $3.3 million as of
September 30, 1999. Interest is payable semi-annually on the loans. The 1995
loans began accruing nominal interest at a rate of 6% per year on March 31,
1997 and payments commenced in June 1997. The effective nominal interest rate
over the life of the 1995 loans is 4.8%. The 1997 loan bears interest at 7%
per year and payments commenced in 1998. We are also required to pay
additional interest equal to 9% of our German subsidiary's annual profits, to
the extent that such profits exceed DEM100,000 per year. The combined annual
interest rate, consisting of nominal interest and additional interest, may not
exceed 7% per year through December 31, 2000. Commencing January 1, 2001 and
January 1, 2003, any amounts still outstanding will accrue additional interest
at the rates of 6% and 7% per year for the 1995 loans and the 1997 loan,
respectively. In addition, at the end of the loan term, which is the earlier
of repayment or December 31, 2005 and December 31, 2007 for the 1995 loans and
the 1997 loan, respectively, our German subsidiary is obligated to pay
terminal interest equal to 25%, 30% and 35% of the amounts loaned under DEM1
million, DEM3 million and DEM2 million agreements, respectively, estimated to
be $1.2 million at the end of the loan term. We have accrued interest of
$930,625 relating to the terminal interest representing approximately 75% of
the terminal interest to be paid at the end of the loan term. TBG has elected
to accept 24,792 shares of our common stock upon the closing of this offering
in total satisfaction of the terminal interest. The number of shares are based
on an assumed initial public offering price of $24.00 per share, and will
increase or decrease based on the final price.

The amounts and timing of our actual expenditures depend on several factors,
including future sales growth, the progress of our product development efforts
and the amount of cash generated or used by our operations. Other than the
$3.3 million debt repayment, we have not determined the amount or timing of
the expenditures in the areas listed above. Pending utilization, we will
invest the net proceeds in short-term, investment grade, interest bearing
instruments.

Dividend policy

We have never declared or paid any cash dividends on our common stock. We
currently intend to retain all available funds for use in our business, and do
not anticipate paying any cash dividends in the foreseeable future. Any future
determination relating to dividend policy will be made at the discretion of
our board of directors and will depend on a number of factors, including
future earnings, capital requirements, financial condition and future
prospects and other factors the board of directors may deem relevant.

Dilution

Our historical net tangible book value as of September 30, 1999 was
approximately $23.0 million, or $26.30 per share, based on the number of
common shares outstanding as of September 30, 1999. Historical net tangible
book value per share is equal to the amount of our total tangible assets less
total liabilities, divided by the number of shares of common stock outstanding
as of September 30, 1999.

Our pro forma net tangible book value as of September 30, 1999 was
approximately $21.6 million, or $1.23 per share, based on the pro forma number
of shares outstanding as of September 30, 1999 of 17,576,685, calculated after
giving effect to:

 . the automatic conversion of 14,842,757 shares of our preferred stock
  outstanding at September 30, 1999 into 14,842,757 shares of our common stock
  on a one-for-one basis;

 . the sale of approximately $1,560,000 in shares of common stock to two German
  consulting firms in a private sale to be completed immediately prior to this
  offering, or 65,000 shares assuming an initial public offering price of
  $24.00 per share;

 . the conversion of debt owed to TBG in the amount of DEM4 million,
  approximately $2.1 million, into 272,108 shares of our common stock upon the
  closing of this offering assuming an initial public offering price of $24.00
  per share; and

 . the issuance of 1,523,451 shares of common stock upon exercise of stock
  options from October 1, 1999 through December 27, 1999.

Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of our
common stock in this offering, and the private sale and the net tangible book
value per share of our common stock immediately afterwards, after giving
effect to the sale of 5,000,000 shares in this offering, the issuance of
24,792 shares of our common stock in satisfaction of accrued interest of
$930,625, and the repayment of $3.3 million of long-term debt from the net
proceeds. This represents an immediate increase in pro forma net tangible book
value of $4.66 per share to existing stockholders and an immediate dilution in
pro forma net tangible book value of $18.11 per share to new investors. The
following table illustrates this per share dilution:

DILUTION

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

The tables and calculations above assume no exercise of outstanding options or
warrants. At December 27, 1999, there were:

 . 1,287,049 shares issuable upon the exercise of options outstanding as of a
  weighted average exercise price of $1.66 per share. This share amount
  consist of 2,475,250 shares issuable upon the exercise of options
  outstanding at September 30, 1999 and 335,250 shares issuable upon the
  exercise of options granted during October 1999, less 1,523,451 shares
  issued upon exercise of options during the period October 1, 1999 through
  December 27, 1999;

 . 176,503 shares issuable upon the exercise of warrants outstanding as of
  December 27, 1999 at a weighted average exercise price of $2.10 per share;
  and


 . 248,750 additional shares available for future grant as of December 27, 1999
  under our 1998 stock plan, and an additional 850,000 shares made available
  for future grant under our stock plans to be adopted at the close of this
  offering. For a description of our stock option and stock purchase plans,
  please see "Management--Employee benefit plans."

To the extent that these options or warrants are exercised, there will be
further dilution to new investors. Please see "Management--Employee benefit
plans" for further information regarding our stock option plan and stock
purchase plan.

If the underwriters exercise their over-allotment option in full, the
following will occur:

 . the number of shares of our common stock held by existing stockholders will
  decrease to approximately 75.4% of the total number of shares of our common
  stock outstanding after this offering;

 . the number of shares of our common stock held by new public investors will
  increase to 5,750,000, or approximately 24.6% of the total number of shares
  of our common stock outstanding after this offering; and

 . an increase in pro forma net tangible book value to $5.18 per share to
  existing stockholders and an immediate dilution in pro forma net tangible
  book value of $17.59 per share to new investors.

Selected consolidated financial data

The following selected consolidated financial data should be read in
conjunction with the consolidated financial statements and the notes to such
statements and "Management's discussion and analysis of financial condition
and results of operations" included elsewhere in this prospectus. The
consolidated statement of operations data for the years ended December 31,
1996, 1997 and 1998 and the nine-month period ended September 30, 1999, and
the consolidated balance sheet data at December 31, 1997 and 1998 and
September 30, 1999, are derived from our consolidated financial statements
which have been audited by Ernst & Young LLP, independent auditors, and are
included elsewhere in this prospectus. The consolidated statement of
operations data for the years ended December 31, 1994 and 1995 and the
consolidated balance sheet data at December 31, 1994, 1995, and 1996 are
derived from audited consolidated financial statements not included in this
prospectus. The consolidated statement of operations data for the nine-month
period ended September 30, 1998 is derived from our unaudited financial
statements included elsewhere in this prospectus. These unaudited financial
statements have been prepared on the same basis as our audited financial
statements, and, in our opinion, include all material adjustments, consisting
only of normal recurring adjustments necessary to present fairly this
unaudited financial information. Historical results are not necessarily
indicative of the results to be expected in the future.

The pro forma net loss per share is calculated as if our convertible preferred
stock and DEM4 million long-term debt owed to TBG as of September 30, 1999,
both convertible into common stock upon the closing of this offering, were
converted into shares of our common stock on the date of their issuance.

Management's discussion and analysis of financial condition and results of
operations

The following discussion of our financial condition and results of operations
should be read in conjunction with the financial statements and the notes to
those statements included elsewhere in this prospectus. This discussion may
contain forward-looking statements that involve risks and uncertainties. As a
result of many factors, such as those set forth under "Risk factors" and
elsewhere in this prospectus, our actual results may differ materially from
those anticipated in these forward-looking statements.

We are a pioneer in the new field of industrial genomics. Since we began
operations in 1994, we have been primarily involved in the research and
development of high definition DNA analysis tools for industrial biomedical
and life science applications.

We are a development stage company. Since our inception, we have incurred
significant losses and, as of September 30, 1999, we had an accumulated
deficit of $37.1 million. To date, our revenues have been solely from research
grants. We began placing MassArray systems at beta sites and with pre-launch
users in July 1999. Information received from these sites is being used to
optimize our product offerings. We expect revenues generated from our
commercial launch to begin during the first quarter of 2000.

We expect to recognize revenues from the sale of both MassArray systems at the
time of placement and disposable products, including SpectroCHIPs. We expect
that each system placed in the field will generate a recurring revenue stream
from the sale of disposables. We also expect the volume of disposables
purchased from each site will increase over time as the customer becomes
familiar with the technology and incorporates MassArray into a broad range of
SNP analysis programs. In addition, we may generate revenue from the sale of
proprietary assays and software products and other services provided to the
customer. In some cases we may retain some rights to assays developed in
collaborations with third parties. This may allow us to offer an expanded line
of products to a broader market. Our sales will be initially driven by the
need for SNP validation and later could expand into the areas of genomic drug
development, diagnostics and agricultural genomics.

Our expenses have consisted primarily of costs incurred in research and
development, manufacturing scale-up, business development and from general and
administrative costs associated with our operations. We expect our research
and development expenses to increase in the future as we continue to improve
and develop products. Our selling expenses will increase as we commercialize
our products. Expansion of our facilities and the additional obligations of a
public reporting entity will also add to our expenses. As a result, we expect
to incur losses for the foreseeable future.

Our current products do not provide sufficient gross margin for us to become
profitable. To become profitable, we will need to develop and introduce new
higher margin products and generate significant sales of disposables.

We have a limited history of operations and we anticipate that our quarterly
results of operations will fluctuate for the foreseeable future due to several
factors, including market acceptance of current or new products, patent
conflicts, the introduction of new products by our competitors, the timing and
extent of our research and development efforts, and the timing of significant
orders. Our limited operating history makes accurate prediction of future
operations difficult or impossible.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OP-
ERATIONS

- -------------------------------------------------------------------------------
RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

REVENUE
Research and development grant revenue decreased to approximately $81,000 in
the first nine months of 1999 from approximately $126,000 in the first nine
months of 1998. As we have approached the commercial launch of our products,
we have not actively pursued grants, and accordingly, revenue from grants has
decreased.

RESEARCH AND DEVELOPMENT EXPENSES
Research and development expenses increased to $7.1 million in the first nine
months of 1999 from $3.6 million in the first nine months of 1998. These
expenses consist primarily of salaries and related personnel costs, materials
costs and costs related to completion of our product development. The increase
resulted from the expansion of our research and development efforts and was
comprised of a $1.6 million increase in salaries & related personnel costs,
additional material costs of $1.2 million and approximately $700,000 of
additional costs directly related to the scale-up of manufacturing for our
SpectoCHIPs.

GENERAL AND ADMINISTRATIVE EXPENSES
General and administrative expenses increased to $5.4 million in the first
nine months of 1999 from $2.6 million in the first nine months of 1998. These
expenses consist primarily of salaries and related costs for executive,
finance and other administrative personnel, general and patent related legal
expenses, and business development expenses. Expenses relating to filing and
pursuing patent applications represented the single largest increase at
approximately $800,000, while continued expansion of administrative resources
to support our growth accounted for the remainder.

AMORTIZATION OF DEFERRED STOCK COMPENSATION
Deferred stock compensation represents the difference between the estimated
fair value of our common stock and the exercise price of options at the date
of grant. During the nine months ended September 30, 1999, we recorded
amortization of deferred stock compensation totaling $3.6 million, including
$1.6 million related to a remeasurement of options originally granted to an
officer in 1997. We anticipate that additional deferred compensation totaling
$3.8 million will be recorded for options granted in October 1999. These
amounts are being amortized over the vesting periods of the individual stock
options using the graded vesting method. We expect to record amortization for
deferred compensation approximately as follows: $761,000 during the quarter
ended December 31, 1999, $3.7 million during 2000, $924,000 during 2001,
$459,000 during 2002, and $214,000 during 2003.

INTEREST INCOME
Interest income increased to $1.2 million in the first nine months of 1999
from approximately $291,000 in the first nine months of 1998. This increase
resulted from higher average balances of cash and cash equivalents and short-
term investments in 1999 from investment of the proceeds from the sale of
Series D Convertible Preferred Stock in late 1998 and early 1999.

INTEREST EXPENSE
Interest expense increased to approximately $576,000 in the first nine months
of 1999 from approximately $230,000 in the first nine months of 1998. The
increase was due to higher average debt levels resulting from additional
indebtedness under our capital lease financing arrangement.

INCOME TAXES
As of September 30, 1999, we had federal and state net operating loss
carryforwards of approximately $24.8 million and $13.1 million. We also have
federal and state research and development tax credit carryforwards of
approximately $410,000 and $200,000 and German net operating loss
carryforwards of approximately $7.2 million. The federal and state net
operating loss and credit carryforwards expire on various dates through 2018.
The German net operating losses may be carried forward indefinitely. Pursuant
to Internal Revenue Code Sections 382 and 388, our net operating loss and
credit carryforwards may be limited due to a cumulative change in ownership of
more than 50%, which occurred during 1998 and which is anticipated to occur
with the offering. However, we do not believe these limitations will
materially impact the use of the net operating loss and credit carryforwards.

YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

REVENUE
Research and development grant revenue decreased to $351,000 in 1998 from
approximately $527,000 in 1997 and from $893,000 in 1996. As we have
approached the commercial launch of our products, we have received funding
from private equity financings and have not pursued grant funding.

RESEARCH AND DEVELOPMENT EXPENSES
Research and development expenses increased to $6.2 million in 1998 from $3.5
million in 1997 and $3.1 million in 1996. The $2.7 million increase from 1997
to 1998 resulted from an additional $1.3 million in personnel costs and
approximately $1.4 million in additional supplies related to the development
of our MassArray system. The increase from 1996 to 1997 resulted primarily
from an increase in the number of personnel and their related costs.

GENERAL AND ADMINISTRATIVE EXPENSES
General and administrative expenses increased to $4.2 million in 1998 from
$1.9 million in 1997 and $1.0 million in 1996. Expenses relating to filing and
pursuing patent applications represented the single largest increase in 1998
at approximately $800,000. These expenses increased because a higher number of
patents were filed worldwide. Expenses related to employing more personnel
represented the remainder of the increase. The increase from 1996 to 1997
resulted primarily from increases in the number of personnel and expansion of
facilities.

INTEREST INCOME
Interest income increased to approximately $397,000 in 1998 from approximately
$57,000 in 1997. The increase was due to higher average balances of cash and
cash equivalents and short-term investments in 1998, resulting from the
investment of the proceeds from the sale of Series C convertible preferred
stock in February 1998. Interest income decreased to $57,000 in 1997 from
$73,000 in 1996 due to slightly lower average cash and cash equivalents during
1997.

INTEREST EXPENSE
Interest expense increased to approximately $613,000 in 1998 from
approximately $308,000 in 1997 and $275,000 in 1996. Interest expense
increased in 1998 due to an increase in borrowings under a capital lease
agreement and from proceeds received from convertible debt funding. The 1997
increase in interest expense resulted from DEM2 million of additional debt
funding.

LIQUIDITY AND CAPITAL RESOURCES
We have funded our operations with $55.6 million of private equity financings,
$6.0 million in loans and convertible loans, and $2.2 million from equipment
financing arrangements. At September 30, 1999,

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OP-
ERATIONS

- -------------------------------------------------------------------------------
cash, cash equivalents and short-term investments totaled $28.0 million
compared to $28.5 million at December 31, 1998. Our cash reserves are held in
a variety of interest-bearing instruments including high-grade corporate
bonds, commercial paper and money market accounts.

Cash used in operations for the nine months ended September 30, 1999 was $9.4
million compared with $5.5 million for the same period in 1998. A net loss of
$15.4 million for the first nine months of 1999 was partially offset by non-
cash charges of $3.6 million for amortization of deferred compensation, $1.3
million for depreciation and amortization expense and an increase of $1.2
million in accounts payable and accrued expenses. Investing activities, other
than the changes in our short-term investments, consumed $3.3 million in cash
during the first nine months in 1999 due to leasehold improvements and
equipment expenditures.

Cash provided by financing activities was $12.5 million for the nine months
ended September 30, 1999 compared to $14.2 million for the same period in
1998. Financing activities included the receipt of net proceeds of $11.8
million from the sale of preferred stock to investors in the nine month period
ended September 30, 1999 and $11.0 million in the nine month period ended
September 30, 1998.

Working capital decreased to $24.8 million at September 30, 1999 from $26.0
million at December 31, 1998. The decrease in working capital was due to our
use of cash in operations, higher accounts payable and accrued liabilities as
a result of increased product and business development, expenses, and payment
of capital lease obligations, offset in part by higher inventory and prepaid
expenses.

As of September 30, 1999, we had an aggregate of $7.2 million in future
obligations of principal payments under capital leases and long-term debt, of
which $0.4 million is to be paid within the next year. We expect to use
approximately $4.2 million of the proceeds of this offering for the repayment
of long-term bank debt and accrued interest. This debt, which originated in
1995 and 1997, is denominated in German deutsche marks, DEM, and totals DEM6
million. For a more detailed description of this bank debt, please see "Use of
Proceeds."

We believe our existing cash, cash equivalents and short-term investments,
together with the net proceeds of this offering will be sufficient to fund our
operating expenses, debt obligations and capital requirements through at least
the next 24 months. Our future capital uses and requirements depend on
numerous factors, including:

 . our success in selling our MassArray system and associated technologies;

 . our progress with research and development;

 . our ability to introduce and sell new products;

 . our sales and marketing expenses;

 . expenses associated with unforeseen litigation;

 . costs and timing of obtaining new patent rights; and

 . regulatory changes and competition and technological developments in the
  market.

Therefore, our capital requirements may increase in future periods. As a
result, we may require additional funds and may attempt to raise additional
funds through equity or debt financings, collaborative arrangements with
corporate partners or from other sources.

We have a $5.0 million bank line of credit, all of which is available for
borrowing. We have no commitments for any additional financings, and we cannot
assure you that additional funding will be available to finance our operations
when needed or, if available, that the terms for obtaining such funds will be
favorable or will not result in dilution to our stockholders.

We could possibly be required to repurchase approximately 65,000 shares sold
to two German consulting firms in a private sale scheduled to close
immediately prior to this offering, and repay the purchase price of their
shares of approximately $1.6 million if we are deemed to have violated Section
5 of the Securities Act of 1933.

IMPACT OF THE YEAR 2000

The computer systems and software programs of many companies and governmental
agencies are currently coded to accept or recognize only two digit entries in
the date code field. These systems may recognize a date using "00" as the year
1900 rather than the year 2000. As a result, these computer systems and/or
software programs may need to be upgraded to comply with such year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities.

STATE OF READINESS

We have made an assessment of the year 2000 readiness of our technology
systems, including our hardware and software in our products and our non-
information technology systems. We were informed by our vendors who provide
the hardware in our products that the hardware we use is year 2000 compliant.
We believe that substantially all of our applications, databases and
infrastructure are year 2000 compliant. We were informed by many of our
vendors of material hardware and software components of our information
technology systems that substantially all of the products we use are currently
year 2000 compliant.

COSTS

As of September 30, 1999, we have expensed approximately $25,000 for assessing
our state of readiness and making upgrades for year 2000 compliance. To date,
we have not experienced any material adverse effect on our business or
operating results as a result of any year 2000 problems. In addition, we have
not deferred any material information technology projects or equipment
purchases, as a result of our year 2000 compliance activities.

RISKS

We are not currently aware of any year 2000 compliance problems relating to
our proprietary software and other products or our information technology or
non-information technology systems that would have a material adverse effect
on our business. We cannot assure you that we will not discover year 2000
compliance problems in our proprietary software and other products that will
require substantial revisions. In addition, we cannot assure you that third-
party software, hardware or services incorporated into our material
information technology and non-information technology systems will not need to
be revised or replaced, all of which could be time consuming and expensive.
Our failure to fix our proprietary software and other products or to fix or
replace third-party software, hardware or services on a timely basis could
result in lost revenues, increased operating costs, the loss of customers and
other business interruptions, any of which could have a material adverse
effect on our business. Moreover, the failure to adequately address year 2000
compliance issues in our proprietary software and other products and our
information technology and non-information technology systems could result in
claims of mismanagement, misrepresentation or breach of contract and related
litigation, which could be costly and time-consuming to defend.

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

CONTINGENCY PLAN
In the event that year 2000-related problems materialize, we maintain
relationships with several suppliers of services and products to mitigate the
risks associated with using suppliers which are not year 2000 compliant.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SHORT-TERM INVESTMENTS
The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities that we invest
in may have market risk. This means that a change in prevailing interest rates
may cause the fair value of the principal amount of the investment to
fluctuate. For example, if we hold a security that was issued with a fixed
interest rate at the then-prevailing rate and the prevailing interest rate
later rises, the fair value of the principal amount of our investment will
probably decline. To minimize this risk in the future, we intend to maintain
our portfolio of cash equivalents and short-term investments in a variety of
securities, including commercial paper, money market funds, government and
non-government debt securities. The average duration of all of our investments
has generally been less than one year. Due to the short term nature of these
investments, we believe we have no material exposure to interest rate risk
arising from our investments. Therefore, no quantitative tabular disclosure is
required.

LONG-TERM DEBT
Our long-term debt is denominated in German deutsche marks. We intend to
convert approximately half of this debt into common stock upon the closing of
this offering, and to repay the rest of this debt in cash from the proceeds of
the offering. If the German deutsche mark increases in value relative to the
US dollar before the conversion or repayment, we will have to issue more
shares or cash to retire the debt. A 1% increase in the value of German
deutsche marks relative to the US dollar would result in a $55,000 unrealized
foreign translation loss.

FOREIGN CURRENCY RATE FLUCTUATIONS
The functional currency for our German subsidiary is the deutsche mark. The
German subsidiary's accounts are translated from the German deutsche mark to
the US dollar using the current exchange rate in effect at the balance sheet
date, for balance sheet accounts, and using the average exchange rate during
the period for revenues and expense accounts. The effects of translation are
recorded as a separate component of stockholders' equity. Our German
subsidiary conducts its business with customers in local European currencies.
Exchange gains and losses arising from these transactions are recorded using
the actual exchange differences on the date of the transaction. We have not
taken any action to reduce our exposure to changes in foreign currency
exchange rates, such as options or futures contracts, with respect to
transactions with our German subsidiaries or transactions with our European
customers. The net tangible assets of our German subsidiary, without regard to
the long-term debt, were $4.6 million at September 30, 1999. A 1% decrease in
the value of German deutsche marks relative to the US dollar would result in a
$46,000 unrealized foreign translation loss.

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

RECENT ACCOUNTING PRONOUNCEMENTS
In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
changes the previous accounting definition of derivative--which focused on
freestanding contracts such as options and forwards, including futures and
swaps--expanding it to include embedded derivatives and many commodity
contracts. Under the statement, every derivative is recorded in the balance
sheet as either an asset or liability measured at its fair value. The
statement requires that changes in the derivatives fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. SFAS
No. 133 is effective for fiscal years beginning after June 15, 2000. We do not
anticipate that the adoption of SFAS No. 133 will have a material impact on
our financial position or results of operations.

BACKGROUND

DNA, GENES AND THE HUMAN GENOME PROJECT
Deoxyribonucleic acid, or DNA, is present in all living cells and is
responsible for determining the inherited characteristics of all living
organisms. Each DNA molecule contains two complementary strands comprised of
four different types of nucleotide bases, commonly known as G, C, A and T. The
order of these letters is called the DNA sequence. Each G on one strand pairs
with a C on the complementary strand, and similarly each A pairs with a T. The
entire DNA content of an organism is called its genome.

The human genome is organized into 46 chromosomes, or two sets of 23
chromosomes, one set inherited from each parent. Each chromosome is one
continuous double-stranded DNA molecule. The DNA contributed by one parent is
called the haploid genome. The DNA content of one haploid genome is
approximately 4 billion bases, which is organized into more than 100,000
distinct genes. Genes are segments of DNA located throughout the chromosomes.
Since parents are not identical, each individual has two similar but slightly
different copies of each chromosome and therefore two copies of each gene.
Genes comprise approximately 5% of the DNA in a human cell. Some additional
amount is used to regulate DNA function. More than 90% of the DNA has no known
function.

All cells contain a full copy of DNA, but each cell type expresses only those
genes necessary for its specific function. When a gene is expressed, a copy of
its DNA sequence, called messenger RNA, is used as a template to direct the
synthesis of a protein. Proteins are composed of 20 different constituents
called amino acids. Three adjacent letters of DNA, known as a codon, direct
the position and identity of one amino acid in a protein. Cells use proteins
to carry out their functions. For example, blood cells use the protein
hemoglobin to transport oxygen and muscle cells use the protein myoglobin to
store oxygen. Likewise, pancreatic islet cells secrete the protein insulin to
regulate blood sugar levels. DNA sequences referred to as regulatory elements
help to determine where a protein is made and in what quantities. For an
individual to be healthy, the correct proteins must be produced at the right
time in the appropriate amounts in the correct cells. DNA variations can
change the properties of a protein, or where, when or how much of a protein is
produced.

In order to develop new medical treatments and diagnostics based on genetic
information, efforts to sequence human DNA began in the mid-1980s when the
technology for sequencing became available. Efforts funded by governments and
foundations began in earnest by the end of the 1980s. These efforts came to be
known as the Human Genome Project. This project is expected to produce a rough
draft of the human DNA sequence by March 2000, with a complete draft expected
in several years. The overall public sector expenditure is expected to
approach $3 billion. In parallel with the public sector effort, a large
private sector effort emerged in the early 1990s. Unlike the public effort
that targets the entire genome, commercial efforts have focused on sequencing
the genes themselves. This private effort claims to have identified many human
genes some of which have been made available for a variety of biological and
biomedical studies.

GENETIC VARIABILITY AND SINGLE NUCLEOTIDE POLYMORPHISMS, OR SNPS
Each individual has two identical copies of many genes, but some genes
inherited from the mother will be different from their counterpart inherited
from the father. A difference in one or more letters of a DNA sequence,
referred to as a genetic variation, can modify the way a gene functions.
Genetic variations lead to a spectrum of observable differences, such as eye
and hair color. Genetic variations are

- -------------------------------------------------------------------------------
32
<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
also a major component of nearly all diseases, including cancer, diabetes and
cardiovascular disease. Many chronic diseases are affected by multiple genetic
variations.

Single nucleotide polymorphisms, or SNPs, are the most common type of genetic
variation. SNPs are a change in a single letter of DNA text, such as replacing
a G with a T in one location and on the complementary DNA strand replacing a C
with an A. Another common variation is the insertion or deletion of one or
several letters. A third common variation is an increase or decrease in the
length of simple repeating DNA sequences. Nearly every person carries numerous
examples of each of these three kinds of variations, some of which can result
in disease.

GENETIC ANALYSIS OR GENOTYPING
The process of determining the SNPs present in an individual is called
genotyping. It is estimated that there are 3 million to 10 million SNPs
inherited from each parent. Some SNPs are a major cause of inherited diseases
and are responsible for most individual differences in drug responsiveness;
however, most SNPs are of no medical consequence. For example, if the third
letter of a codon varies, the result is usually to produce the same amino acid
or one with similar properties. However, to date, thousands of SNPs have been
identified as medically relevant. Many genes exist in highly redundant sets so
that even if one is totally removed, there are no functional consequences. We
believe that only one SNP in a thousand may be medically relevant to disease
susceptibility or responsiveness to disease therapy. To capture this
information, tens of thousands of SNPs will have to be measured in each
individual.

Existing DNA sequence databases with samples from multiple individuals contain
many clues about potential sites in the human genome where SNPs occur.
Sequence variation between these individuals may suggest the presence of a
SNP. Ongoing sequencing efforts promise to increase the amount of available
sequence data tremendously and should discover most human SNPs within the next
few years.

After a SNP is discovered, its potential relevance for human health must be
validated by determining how common the variation is in different segments of
the population. To identify the small subset of SNPs that occur with the
greatest frequency in human disease or are responsible for variations in drug
responsiveness, hundreds of millions of SNP measurements must be made and
correlated with health and other physical and mental features of interest.
SNPs with a validated medical relevance may be used for drug development and
human medical diagnostics. Identification of these SNPs will require a highly
accurate, high throughput DNA analysis technology at a competitive cost.

PERSONALIZED MEDICINE OR PHARMACOGENOMICS
It has long been known that people respond differently to the same drug. The
field of pharmacogenomics studies these variations in drug response based on
genetic differences. The emerging ability to correlate drug responses with
SNPs promises to enable doctors to prescribe appropriate drugs to patients
with the goal of maximizing drug response and minimizing side effects. For
example, a test that could distinguish poor responders from good responders to
drugs in which more than one therapeutic alternative exists could
significantly reduce health care costs. In addition, pharmacogenomics may
allow pharmaceutical companies to include a genetic component in the design of
clinical trials so that the candidate drug is targeted to individuals with a
specific genotype. Genetic variations shown to correlate with poor efficacy
could be used as a basis for excluding non-responders from clinical trials
thereby potentially improving results and reducing the costs of clinical
trials.

SNPS IN AGRICULTURE AND LIVESTOCK
As living organisms, plants and animals are composed of cells that contain
DNA. As with humans, genetic variations in plants and animals result in
differences in species characteristics. For example, plants

- -------------------------------------------------------------------------------
                                                                             33
<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
may have SNPs responsible for differences in resistance to insects and
herbicides or agricultural yields. Likewise, animals may have SNPs responsible
for traits such as variations in milk production, fat content of meat or
fertility. Plant and animal SNPs can be exploited through selective breeding
to develop plants and animals with desired quality traits.

SNP MARKET
The SNP genotyping market represents a significant portion of both the biochip
market and the DNA sequencing market. The SNP genotyping market can be divided
into three segments:

 . confirmation of new sites of genetic variation in DNA, which typically
  requires the analysis of a SNP in up to a hundred people;

 . determination of the medical importance of SNPs, which typically requires
  the analysis of a SNP in a few thousand diseased and healthy people; and

 . utilization of SNPs in genomics-based drug development, disease
  predisposition determination and diagnostic test development, which may
  require the analysis of multiple SNPs in millions of people.

Several companies claim to have identified, in the aggregate, more than 50,000
SNPs, and The SNP Consortium, comprised of drug companies and public entities,
has announced a group effort to discover 300,000 more. If The SNP Consortium
successfully identifies 300,000 SNPs and seeks to discover the associated
disease genes, they would have to conduct a case study involving several
thousand people, which would require the analysis of hundreds of millions of
SNPs.

CURRENT GENOMICS ANALYSIS TOOLS AND LIMITATIONS

Current DNA analysis technologies have been developed primarily to conduct DNA
research including DNA sequencing and expression profiling. Presently, the two
leading methods are gel electrophoresis and hybridization.

Gel electrophoresis measures how far a DNA fragment migrates through the pores
of gels in response to an applied electrical field over a fixed time interval.
DNA can be sequenced by using enzymes to copy a DNA sequence. The enzymes
begin at a fixed point and then terminate at all positions where an A occurs.
Gel electrophoresis is then used to measure the lengths of the terminated
sequences and thereby the location of all As. When this process is repeated
three more times for C, T and G, the resulting information can be lined up to
generate a complete sequence. In order to make this method totally accurate,
the same experiment must be repeated multiple times. In a single run,
commercial DNA sequencers using this gel-based method can measure up to 600
bases with a statistically significant error-rate.

Hybridization arrays, or biochips, use single stranded DNA fragments
immobilized on a flat surface in known positions. These are powerful tools for
the analysis of gene expression, but can also be used for gene sequencing.
When used for gene sequencing, DNA fragments of varying lengths labeled with a
fluorescent tag are washed over the surface of the biochip. These DNA
fragments then specifically interact, or hybridize, with a complementary
sequence immobilized on the biochip and can be detected using a fluorescent
microscope. Because the position of the complementary sequence on the biochip
is known, the sequence of the target DNA fragment can be determined by reading
the biochip. However, because DNA fragments sometimes bind to strands that are
not fully complementary, hybridization arrays do not correctly detect all of
the sequence information in a target sample.

Gel electrophoresis and hybridization play an interim role in determining SNP
function and analysis as these methods are well accepted and established for
research applications. However, neither of these two

- -------------------------------------------------------------------------------
34
<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
methods is ideally suited to the analysis of sequence variations. In both
cases, the analytical process examines many nucleotides of a sequence even
though the target variation may occur at a single site. This increases the
cost, complexity and time involved in the analytical process. In order to be
able to measure thousands of SNPs in thousands of samples, one must focus on
the SNPs themselves with methods that are cost-effective, accurate and fully
automated.

At the site of any SNP, one must analyze simultaneously the variant inherited
from each parent. If each parent has a different SNP at the same position, the
difficulty of detecting those variations is magnified because only one-half of
the DNA from each parent is available to generate a signal. In addition, in
practice, one SNP variant may be present at a lower concentration than the
other and therefore may be undetectable or generate an ambiguous signal using
conventional methods. Using gel electrophoresis and hybridization, the
detection of these multiple SNP variants is therefore often unreliable.

To reduce costs, many users of SNP assays are trying to perform two or more
assays in a single tube and read the results simultaneously. This may involve
different SNPs in the same individual or the same SNP in different
individuals. Current gel technology limits this process to four available
dyes, and simultaneous assays involving multiple individuals are impossible on
biochips. However, biochips are theoretically capable of simultaneously
analyzing many SNPs for a single individual, but their utility is limited by
low accuracy. The large quantity of reagents and labor-intensive data
processing needed to achieve useable results are also cost limitations when
using current technologies for large-scale genotyping. Reagent costs represent
most of the sample preparation costs. Data analysis costs associated with
current gel or hybridization-based assays using fluorescent detection are
estimated to be most of the overall costs.

Errors in SNP analysis have serious consequences. In studies to correlate
identified SNPs with disease conditions, it has been estimated that to
compensate for a 1% error rate in individual measurements, the study
population would have to increase by a factor of three. This significantly
increases the cost of a SNP study. In addition, in order to accurately
identify a real SNP from a sequencing error when the sequencing error occurs
with a frequency of 1%, a suspected SNP has to be verified through repetitive
sequencing. When identifying 10,000 SNPs in an individual, 100 SNPs may be
incorrectly determined using gel electrophoresis, with no ability to determine
where the errors occurred. Therefore, the value of using gel electrophoresis
as a SNP analysis tool is dramatically reduced unless the test is repeated
several times. As a result, when genotyping SNPs on an industrial scale, a 1%
error rate becomes cost-prohibitive.

THE SEQUENOM SOLUTION--INDUSTRIAL GENOMICS

We are a pioneer in the new field of industrial genomics. To draw conclusions
from huge data sets associated with genotyping, we have developed a highly
accurate, high throughput and cost-effective technology that addresses the
demand for large-scale SNP analysis. Our MassArray system represents a novel
approach to genotyping by combining our proprietary enzymology and software
processing of biological data, or bioinformatics, in a miniaturized chip-based
format with the proven technology of mass spectrometry. The accuracy, high
throughput, miniaturization and automation to minimize labor represent major
cost savings potentials.

ACCURACY
The MassArray system analyzes molecules directly and accurately by determining
their molecular weight, an intrinsic property. Our technology eliminates the
use of labels, such as fluorescent labels, which is an indirect way of
analyzing molecules and is a common source of ambiguous results. Therefore,
because

- -------------------------------------------------------------------------------
                                                                             35
<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
we capture direct information about molecules, we are able to obtain a high
level of accuracy and eliminate the need to do repetitive testing of each
sample.

THROUGHPUT
Our MassArray system can analyze a sample in three seconds, which is
significantly faster than currently available gel electrophoresis and
hybridization processes. These processes can require minutes to hours to
analyze a sample. In addition, our system eliminates the need for repetitive
testing of every sample, thereby increasing throughput, or the number of
different samples that can be analyzed in a given time period. Throughput
using the MassArray system can be further enhanced by full automation and also
by running more than one experiment simultaneously.

FLEXIBILITY
MassArray can be rapidly reconfigured for new analyses. A test to analyze a
newly discovered SNP can be designed in several days. In addition to SNPs,
simple sequence repeats, short DNA sequencing reads, and the analysis of
proteins and metabolites can all be carried out using the same MassArray
technology.

COST
Our MassArray system significantly reduces the costs associated with SNP
analysis by reducing reaction volume and reagent requirements, enhancing data
processing and eliminating repetitive testing of every sample to verify
results. Our proprietary SpectroCHIP is capable of working with nanoliters,
which is one thousandth of the sample volume generally used with other
technologies. This ability to miniaturize the sample volume significantly
reduces reagent costs. Our proprietary bioinformatics reduce expensive data
interpretation time and labor by rendering raw data points directly
interpretable without extensive data processing and allowing for significant
data compression.

SEQUENOM STRATEGY

Our goal is to become the leader in the emerging markets of industrial
genomics and diagnostics by making our MassArray system the market standard
for industrial scale SNP analysis. Our strategy is to capitalize on the
quickly emerging demand for genotyping in the areas of drug target discovery,
drug development, DNA diagnostics, patient stratification by genetic traits,
clinical trials, seed development and livestock breeding. Key elements of our
strategy consist of the following:

DEVELOP RECURRING REVENUE STREAM THROUGH DISPOSABLE PRODUCT SALES
We seek to establish an installed base of instruments that require the use of
various disposables, including our BiomassPROBE kits and single-use
SpectroCHIPs. As our installed base of MassArray systems grows, we expect the
majority of our ongoing revenue stream will consist of sales of these
disposables.

FOCUS ON KEY ACCOUNTS AND PRODUCT AREAS
We are seeking to penetrate the genotyping market by establishing commercial
relationships with opinion leaders and identifying areas of potential
widespread interest. We have initiated this effort by selecting highly visible
academic, government and commercial centers to validate our MassArray system
in beta site testing. In addition, we intend to develop proprietary disposable
assays and software products that are useful for popular areas of scientific
investigation--first as research tools to confirm the association of
particular SNPs with particular diseases and subsequently as diagnostic kits
that can be sold for basic SNP profiling.

RETAIN COMMERCIAL RIGHTS
We will seek to retain commercial rights to tests that we develop on behalf of
or together with third parties in exchange for providing our assay development
capacity and expertise. By obtaining commercial rights to assays that we
initially develop for key accounts, we will seek to develop a broad product
offering that will appeal to a large group of potential customers. We intend
to identify in collaboration with these customers SNP sets for which genetic
function has been determined and validated to enable the multi-dimensional
understanding of the medical and environmental components of disease. Together
with our customers, we intend to develop knowledge-based genomic products that
combine pharmaceutical, medical and genetic information, such as validated SNP
sets for specific diseases.

ADDRESS MULTIPLE MARKET SEGMENTS
We are introducing our technology into existing markets that have an immediate
need for SNP validation and high throughput genotyping. We will seek to expand
our marketing efforts as additional SNP analysis becomes necessary for genomic
drug development, clinical DNA diagnostics, pharmacogenomics and agricultural
genomics.

EXPAND APPLICATIONS FOR MASSARRAY TECHNOLOGY
Because molecular weight is an intrinsic property of all molecules, our
MassArray technology can serve as a platform for the analysis of many
biomolecules, such as proteins, carbohydrates and metabolites. This leads to
the understanding of the multidimensional aspects of genetic diversity,
including how DNA, RNA, proteins and resulting metabolites contribute to
traits, such as drug response and disease susceptibility. We intend to use
this flexibility to develop new products for applications in areas other than
DNA and SNP analysis.

MASSARRAY TECHNOLOGY

The starting point for SNP analysis using the MassArray system is genomic DNA
that is easily accessed in a sample of biological material such as blood. A
small amount of blood provides sufficient material to allow tens of thousands
of SNPs to be analyzed in one individual. DNA is prepared by standard
procedures that break open the blood cells, release the DNA and discard other
material. Next, specific DNA regions, about 200 base pairs in length, are
amplified by enzymatic reactions into multiple copies to produce more
concentrated samples for easier analysis. The amplified fragments are then
attached by one strand to a solid surface and the non-immobilized strands are
removed by standard denaturation conditions. The immobilized single strand
then serves as a template for additional automated enzymatic reactions that
produce the analytical samples. The products of these reactions are removed
from the solid surface prior to mass spectrometry. All these steps are
performed in the same reaction tube lending the entire process to full
automation. Very small quantities of the products, typically five to ten
nanoliters, are transferred with the SpectroJET nanoliter dispensing system
onto the SpectroCHIP for subsequent automatic analysis with the SpectroSCAN
mass spectrometer. Because the four different text letters have different
weights, measuring the weights reveals the identity of the letters. The
Genolyzer software then calculates, records, compares and reports the
genotypes at the rate of three seconds per sample.

Our fundamental proprietary technology is based on the integration of four
components:

 . mass spectrometry;

 . chips as miniaturized launching pads;

 . MassArray applications and assays; and

 . bioinformatics.

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

MASS SPECTROMETRY
Our MassArray system has enabled the use of mass spectrometry for high
throughput automated SNP analysis. Using mass spectrometry to measure
relatively small molecules is a proven technology because it directly and
accurately determines molecular weight. While mass spectrometry has existed in
many variations for several decades, it could not be used for larger
biomolecules because they were fragmented during the process and therefore
could not be measured as whole molecules.

Our MassArray system uses technology called MALDI-TOF, or Matrix-Assisted-
Laser-Desorption/ Ionization-Time-of-Flight, mass spectrometry. Through the
combination of MALDI-TOF and our proprietary SpectroCHIP and enzymology, we
are now capable of effectively analyzing biomolecules in an automated mode. In
the MALDI-TOF process, the target molecules are mixed with light-absorbing
molecules to form a crystalline matrix on the surface of our SpectroCHIP. In a
process known as desorption, this matrix is hit with a pulse of laser beam.
The laser energy vaporizes the matrix molecules that then carry the target
molecules aloft. During the process, some of the molecules acquire a charge,
or become ionized. Next an electrical field pulse launches the charged
molecules down a flight tube toward a detector. The time between the
electrical field pulse and collision with the detector is measured, and is
referred to as time-of-flight. Time-of-flight is directly correlated to
molecular weight because large molecules fly slower than small molecules. All
the steps in the MALDI-TOF process are accomplished in less than a thousandth
of a second.

CHIPS AS MINIATURIZED LAUNCHING PADS
SpectroCHIPs are flat silicon wafers with an array of 96 small, evenly spaced
water-attracting spots surrounded by water-repelling surface areas. Because
biomolecules are water soluble, they migrate to the water-attracting spots.
These spots are treated with the light-absorbing matrix that makes the mass
spectrometry of biomolecules possible. As such, our proprietary SpectroCHIPs
serve as a launching pad for vaporizing a variety of biomolecules
appropriately prepared for use with the MassArray system. In addition, the
SpectroCHIPs are essential for the miniaturization and automation of the
MALDI-TOF process. A SpectroCHIP's high precision surface structure allows
very small samples to be accurately positioned and distributed uniformly into
an array format which serves as an effective launching pad for the automated
MALDI-TOF process.

The DNA samples are transferred from a microtiter plate to the spots on the
chip using our SpectroJET nanoliter dispensing unit. Ten chips then can be
positioned on a cartridge and transferred to the SpectroSCAN array reading
mass spectrometer. The mass spectrometer utilizes our proprietary Genolyzer
software and sequentially scans the positions on the array in a fully
automated mode, completing each scan within three seconds. This proprietary
technology to shrink the scale of samples from microliter to nanoliter volumes
is the key element for highly accurate and automatic data acquisition.

ASSAYS AND ENZYMATIC REACTIONS
A key element of the MassArray system is the BioMASS assay. An assay is a test
that provides analytical information about a reaction of interest, such as the
weight of a biomolecule. In order to use our MassArray system, the user must
prepare the sample using the BioMASS assay. The central components of any
BioMASS assay are ingredients such as beads for immobilization and buffer
solutions for conditioning the sample necessary for mass spectrometry
analysis. Every SNP analysis using our MassArray system requires the use of a
BioMASS assay. Prior to the BioMASS assay, DNA must be extracted from cells
and a specific segment must be amplified using commercially available kits.
The BioMASS assay includes all of the ingredients required to prepare a DNA
fragment for SNP analysis, except the enzymes and nucleotide building blocks
which are necessary for the primer extension reaction. The primer extension
reaction known as a BiomassPROBE assay is the step where a known sequence of

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

<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
DNA, known as a primer, binds to a specific region of DNA in which a SNP is
located. Users of the MassArray system can prepare their own primer extension
reaction, or we can collaborate with customers to develop a customized primer
extension reaction by way of assay design. When we develop primer extension
reactions for the analysis of specific SNPs, customers can purchase a specific
BiomassPROBE assay from us that contains the customized primer extension
reaction for the SNP of interest. We currently offer a generic BiomassPROBE
assay kit and are collaborating with our beta site and pre-launch users on a
variety of SNP-specific BiomassPROBE assays. In the future, we intend to
develop chips that allow the performance of BiomassPROBE reactions in a
miniaturized format on the surface of the chip.

BIOINFORMATICS
The Genolyzer software calculates, records, compares and reports the genotypes
at the rate of three seconds per sample. It includes advanced digital signal
processing, data compression and interpretation to achieve full automation of
the analysis and archiving of molecular weight signals as SNP genotypes. This
software distinguishes between signal and noise, identifies patterns that
correspond to assays and interprets the signals as SNP genotypes without
labor-intensive data processing.

PRODUCTS

We have developed a suite of products that we collectively call the MassArray
system. The MassArray system consists of the SpectroSCAN array-scanning mass
spectrometer, SpectroJET nanoliter-dispensing unit, a MassArray kit and the
Genolyzer MassArray workstation. The MassArray kit contains the BiomassPROBE
assay including the SpectroCHIP, buffer solutions and enzymes. The hardware
components, including the mass spectrometer and the dispensing unit, are off-
the-shelf instruments modified to run our MassArray technology.

We are currently in beta site testing of our system for high throughput,
highly accurate SNP analysis. We commenced a commercial launch during the
fourth quarter of 1999. To date, our MassArray system has been installed at
six sites, all of which are beta testing our product. Current sites include
Genzyme, USDA, National Institutes of Health and National Cancer Institute in
the United States and University of Munster and GLE Medicon in Germany.

MASSARRAY SYSTEM
Our MassArray system consists of hardware, software and disposable components:

HARDWARE COMPONENTS
The MassArray system is a series of integrated hardware components that
processes prepared DNA samples for SNP reading and analysis. The 96-well
microtiter plates contain prepared samples of extended DNA fragments. Samples
from each well are then transferred by the dispensing unit onto an array of
individual water-attracting spots that are located on the surface of the
SpectroCHIPs. The SpectroCHIPs are then run through the mass spectrometer for
SNP reading and analysis.

Sample preparation system and automation
The MassArray system has been designed to be either partially automated using
a customized 96-channel microliter dispenser or fully automated with the
addition of our automated process line for users with industrial-scale
throughput needs. Our process line links several liquid-handling modules using
a robot to fully automate the DNA sample preparation process including
amplification, enzymatic extension and conditioning for SNP analysis. The
process line has been designed for a capacity of up to 100-microtiter plates
per 24 hours.

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

SpectroJET nanoliter-dispensing unit
The SpectroJET nanoliter-dispensing unit is a liquid-handling module that
transfers samples from microtiter plates to the SpectroCHIP. The SpectroJET
dispenses nanoliter volumes of DNA samples onto precise locations on the
SpectroCHIP's surface.

The reading system
The SpectroSCAN array mass spectrometer is the analytical component of the
MassArray system adapted specifically for the analysis of our SpectroCHIPs. We
have adapted the mass spectrometer to analyze interchangeable cartridges
holding 10 SpectroCHIPs in the SpectroSCAN. This dramatically improves the
automation and throughput of our MassArray system because all the positions on
the 10 chips can be analyzed in a single, automated, unattended run. The
SpectroSCAN separates, detects and characterizes the SNPs according to their
different molecular weights.

SOFTWARE COMPONENT

Interpretation software
Our suite of software products, called the MassArray Genolyzer, incorporates
proprietary modules for molecular weight recognition and data compression and
interpretation. The software correlates a reading from the SpectroSCAN with a
genotype in the SNP sample. The MassArray technology allows the Genolyzer
software to interpret raw data without extensive processing. This reduces the
amount of time and computer resources necessary and increases the reliability
for SNP analysis. The MassArray Genolyzer runs on Windows NT and uses an
Oracle database.

DISPOSABLE COMPONENTS

The SpectroCHIP
The key component of our MassArray system is our SpectroCHIP, a small,
approximately 2x3 cm, silicon chip. The SpectroCHIP allows for reliable and
automated scanning of samples of the array and substantially increases the
capacity of MALDI-TOF mass spectrometry. Additional throughput can be obtained
by simultaneously preparing DNA fragments for multiple SNP analysis, a process
referred to as multiplexing. Samples are placed on the surface of the
SpectroCHIP using our SpectroJET nanoliter- dispenser. SpectroCHIPs are
designed for single-use only and we expect their consumption to generate a
recurring revenue stream.

MassArray kit
The MassArray kit consists of a BiomassPROBE assay including the SpectroCHIP,
buffer solutions and enzymes. Each kit can be used to read and analyze 10
SpectroCHIPs for a total of 960 reactions. We have in-house expertise to
design specific assays in collaboration with our customers that deliver highly
accurate results. In addition, our assays serve a wide range of applications
and can be designed for simultaneous analyses.

POPULATION-BASED DNA BANK
We have established a population-based DNA bank as a value-added universal
reference tool for demonstrating the medical importance of genetic variances
potentially involved in the development of diseases. We intend to sell access
or license subscriptions to this resource to pharmaceutical and genomics
companies to validate the existence of potential SNPs. Our bank complements
the patient-based DNA banks collected by these potential customers, which are
typically disease specific. We believe the data sets derived will represent
essential tools for decision making in genomic drug development and the
interpretation of diagnostic and genetic profiling results.

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

BUSINESS

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

Our DNA bank currently consists of approximately 7,000 individual samples
collected from the North American continent. These samples were collected
using stringent criteria and are sorted by age, sex and ethnicity. We have the
capacity to increase the size of our bank to include tens of thousands of
samples.

FUTURE PRODUCT DEVELOPMENT
Our product development efforts will seek to provide value-added applications
for a broader customer base and advanced MassArray systems that offer reduced
cost and higher throughput.

384 SPECTROCHIP
We intend to introduce a SpectroCHIP with 384 sample spots on the chip
surface. The size of the silicon chip will remain the same. This chip may
significantly increase sample throughput and reduce reagent consumption per
sample.

FUTURE-GENERATION FUNCTIONALIZED SPECTROCHIP
We intend to further miniaturize by moving some of the DNA sample preparation
steps onto the chip surface. With the functionalized SpectroCHIP, the
enzymatic reactions will take place on the surface of the chip thereby
eliminating the need for the microtiter plate, providing a significant
reduction in reaction volumes.

THE MASSARRAY INTEGRATED SYSTEM AND BIOINFORMATICS
The implementation of the functionalized chip should allow us to integrate all
steps of the DNA analysis process, including sample preparation, into one
automated system. We intend for the MassArray integrated system and
bioinformatics to be compatible with all leading commercial and public domain
genetic database formats so customers will be able to integrate the MassArray
system seamlessly into whichever downstream analytical processes they prefer.

FUTURE APPLICATIONS
Our MassArray system is not restricted to DNA analysis. It can analyze a broad
range of molecules of medical and biological importance, such as proteins,
carbohydrates and metabolites. We intend to make enhancements to our MassArray
system for the analysis of additional medically relevant biomolecules.

COMMERCIAL LAUNCH PLAN

We are a development stage company. To date, we have received no revenue from
our commercial operations.

PRE-LAUNCH AND BETA TESTING PROGRAM
In July 1999 we started the implementation of our pre-launch and beta testing
program with the placement of six MassArray systems. All six of our pre-launch
sites are part of our beta testing program. Our beta test program agreements
generally include a time period of 6 to 18 months in which the users receive a
MassArray system, SpectroCHIPs and site support free of charge. In exchange
for their participation in the program, the user must provide us with
information regarding system performance and assay results. One of our beta
test site customers has agreed to purchase our MassArray system. In addition,
some of our agreements require the user to make one or more payments during
the beta test period. Amounts received under these arrangements are recorded
as customer advances and total $100,000 as of September 30, 1999. Costs
related to these arrangements totaled approximately $700,000 through December
31, 1999, and are not expected to exceed $3 million for the remaining term of
the arrangements. We believe these arrangements have the following value:

  . customer feedback has enabled us to enhance our products;

  . our association with these beta sites is expected to provide validation
    of our system since these collaborators are highly visible; and

  . we will eventually derive revenue if the customers accept our products.

<PAGE>

BUSINESS

- -------------------------------------------------------------------------------
Product design, which includes feedback from our customers, has progressed to
a stage where we are able to commercially launch our product. The pre-launch
users were selected based on the following criteria:

 . those entities within the genomic community with high visibility, proven
  expertise and which generally adopt new technologies before others;

 . coverage of diverse programs in basic genomic research, agricultural
  genomics, human DNA diagnostics and genomic drug discovery and development;

 . substantial genotyping demands in terms of both sample volumes and
  number/complexity of assays to be designed;

 . willingness and ability to provide beta testing feedback; and

 . potential for conversion into a commercial customer.

We have placed MassArray systems with:

 . United States Department of Agriculture Meat Animal Research Center;

 . Genzyme Corporation;

 . National Cancer Institute;

 . National Institutes of Health--Centers for Disease Control and Prevention;

 . University of Munster, Institute for Clinical Chemistry and Laboratory
  Medicine; and

 . GLE Medicon GmbH, Hamburg.

KEY ACCOUNT PRODUCT LAUNCH
We commercially launched the MassArray system through a key account strategy
during the fourth quarter of 1999. We have initiated this effort by selecting
highly visible academic, government and commercial centers to validate our
MassArray system in beta site testing. We intend to focus on these users in
order to establish our MassArray system as the method of choice in SNP
analysis.

SALES AND MARKETING
Our sales strategy is to initially place systems and then promote ongoing
disposables and assay sales and system upgrades. The initial placement is
executed by a business development team with expertise in the pharmaceutical
industry, drug development and contract marketing. Identification and active
development of lead customer contacts is based on a thorough knowledge of the
marketplace and supported by highly visible scientists employed by or
associated with us. The sales and marketing team, which has core competencies
in molecular biology, biochemistry, microfluidics and mass spectrometry,
focuses on ongoing disposables and new product sales. These teams collectively
consist of 12 people and are based out of our San Diego, Boston and Hamburg
offices. We expect to add additional business development and sales and
marketing team members to commercialize our MassArray system.

All our facilities have MassArray systems available for demonstration and
customer training purposes. Fully automated high throughput process lines have
been installed in San Diego and Hamburg for large-scale assay design projects
and high value marker function programs.

OPERATIONS

We manufacture SpectroCHIPs, required reagents and Genolyzer software at our
San Diego facility. Total current capacity of this facility is estimated at
100,000 SpectroCHIPs a year with the ability to double our manufacturing
capacity at the existing facility.

The manufacturing area is designed to optimize material flow and personnel
movement with all the manufacturing and quality control operations located in
one area. Critical components are produced in an environmentally controlled
clean room and isolated from the rest of the facility in compliance with
quality system requirements, or QSRs, and ISO 9001 registration standards.
Access and safety features are designed to meet federal, state and local
health ordinances.

We have established some and intend to develop additional alternate/multiple
sources of system components other than those produced in-house. Current major
equipment suppliers are Bruker Datonik GmbH and PE Biosystems for mass
spectrometers, GeSIM GmbH for the nanoliter-dispensing unit, Beckman
Instruments, Inc. for the 96-channel dispenser, and Robocon Incorporated for
the robotic components of the automated process line.

We utilize a company-wide enterprise resource planning system to manage and
control our material and product inventories. This system encompasses product
costing, materials procurement, production planning and scheduling, inventory
tracking and control, product engineering and configuration control, with
links to document control for all manufacturing, quality control, quality
assurance and regulatory compliance procedures.

INTELLECTUAL PROPERTY

To establish and protect our proprietary technologies and products, we rely on
a combination of patent, copyright, trademark and trade secret laws, as well
as confidentiality provisions in our contracts.

We have implemented an aggressive patent strategy designed to provide us with
freedom to operate and facilitate commercialization of our current and future
products. Focusing on a global economy, our patent portfolio reflects our
transatlantic nature and includes 47 pending patent applications in the United
States and corresponding international and foreign filings in major industrial
nations. We currently own nine and license five issued patents in the United
States and have received notices of allowances for five additional patent
applications. We also own two foreign issued patents.

Our patent strategy uniquely positions us by providing patent protection for
systems and technology that allows the direct detection of biomolecules
without labels using mass spectrometry in a manner amenable to high throughput
genotyping.

The issued, allowed and pending patents distinguish us from competitors by
claiming proprietary methods for directly genotyping DNA and other
biomolecules by measuring the mass of the molecules without requiring labels
for detection. Claims to these novel methods include protection for carrying
out biopolymer purification and diagnostic methods in solution or directly by
immobilization on solid supports such as beads or chip surfaces. These methods
also allow multiplexing or analysis of more than one sample both in a single
reaction and as arrays of compounds allowing the system to be easily amenable
to high throughput genotyping. Industrial genomics is possible because mass
spectrometric analysis can be miniaturized and therefore automated. We have
extensive patent protection for novel nanoliter liquid dispensing systems and
pending claims to multifunctional solid surfaces containing nanoliter sized
elements including our SpectroCHIP. Generally, US patents have a term of 17
years from the date of issue for patents issued from applications filed with
the US Patent Office prior to June 8,

- -------------------------------------------------------------------------------
                                                                             43

- -------------------------------------------------------------------------------
1995, and 20 years from the application filing date or earlier claimed
priority date in the case of patents issued from applications filed on or
after June 8, 1995. Patents in most other countries have a term of 20 years
from the date of filing the patent application. Our issued United States
patents will expire between 2013 and 2017. Our success depends to a
significant degree upon our ability to develop proprietary products and
technologies. We intend to continue to file patent applications as we develop
new products and technologies.

Patents provide some degree of protection for our intellectual property.
However, the assertion of patent protection involves complex legal and factual
determinations and is therefore uncertain. In addition, the laws governing
patentability and the scope of patent coverage continue to evolve,
particularly in the areas of molecular biology of interest to us. As a result,
there can be no assurance that patents will issue from any of our patent
applications or from applications licensed to us. The scope of any of our
issued patents may not be sufficiently broad 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 the laws of the United States and Canada. In view of these
factors, our intellectual property positions bear some degree of uncertainty.

We also rely in part on trade secret protection of our intellectual property.
We attempt to protect our trade secrets by entering into confidentiality
agreements with third parties, employees and consultants. Our employees and
consultants also sign agreements requiring that they assign to us their
interests in patents and copyrights arising from their work for us. All
employees sign an agreement not to compete unfairly with us during their
employment and upon termination of their employment, through the misuse of
confidential information, soliciting employees, soliciting customers, and the
like. However, it is possible that these agreements may be breached or
invalidated and if so, there may not be an adequate corrective remedy
available. Despite the measures we have taken to protect our intellectual
property, we cannot assure you that third parties will not breach the
confidentiality provisions in our contracts or infringe or misappropriate our
patents, copyrights, trademarks, trade secrets and other proprietary rights.
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 technology. Therefore, the measures we are taking to protect
our proprietary rights may not be adequate.

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
technology 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, 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 technology, 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 or financial condition.

COLLABORATION AND LICENSE AGREEMENTS

We have a collaboration agreement with Bruker-Franzen Analytik GmbH under
which we cooperate in the manufacture, marketing and customer service of a
product designed for the exclusive processing of our SpectroCHIPs under a
joint Bruker-Franzen-Sequenom label. Under the agreement, Bruker-Franzen
designs, manufactures and supplies the product to the market. We provide
nucleic acid analysis services to customers and to corporate partners using
our MassArray system and develop, manufacture and market SpectroCHIPs for
various applications. Either party may terminate this agreement upon 12
months' notice.

We have entered into a patent and know-how license agreement with the Trustees
of Boston University under which Boston University granted to us a worldwide
license to some of its patents as well as technical assistance, and we agreed
to make royalty payments. Boston University may license the patents to others
under specified circumstances if we fail to put the technology to commercial
use or make it available to the public. We may terminate this agreement upon
written notice to the university. In any event, this agreement will expire
when the last licensed patent expires.

We have entered into a license agreement with The Johns Hopkins University
under which the university granted to us a worldwide license to some of its
patents related to mass spectrometer instruments. Johns Hopkins also agreed to
provide related technical assistance. We agreed to pay a processing fee,
maintenance fee and to make royalty payments. Johns Hopkins reserves specified
rights to the patents in the event that we fail to put the technology to
commercial use or make it available to the public. We may terminate this
agreement upon written notice to the university. In any event, this agreement
will expire when the last licensed patent expires.

We have an original equipment manufacturer supply and license agreement with
PerSeptive Biosystems, Inc. under which we purchase Mass Spectrometry products
at a discount from PerSeptive for incorporation into our products. Our right
to resell the products under the agreement is limited in geographical scope.
In connection with this agreement, PerSeptive also granted us a right to use
the patents and other intellectual property incorporated into the products
that we purchase from PerSeptive under the agreement. The term of the
agreement is for three years after the date it was signed. However, the
agreement may be terminated earlier for reasons of default or insolvency of a

We also entered into a license agreement with Prof. Dr. Franz Hillenkamp, a
member of our scientific advisory board, under which Dr. Hillenkamp granted us
licenses to specified present and future patents in exchange for royalty
payments. We agreed to refund all of Dr. Hillenkamp's expenses that he had
incurred or will incur in connection with applying for, maintaining and
defending the licensed patents. This agreement terminates at the end of the
tenth calendar year after the first calendar year for which licenses are paid.

As of December 31, 1999, we had incurred costs of approximately $1.5 million
in connection with these collaboration and license agreements. During the life
of the these agreements, we may be obligated to pay royalties ranging from 1%-
5% of the sale of the products relating to these agreements. As of September
30, 1999, we had made no commercial sales of products under these agreements.

COMPETITION

The markets for our products are very competitive, and we expect the intensity
of competition to increase. Currently, we compete primarily with other
companies performing similar tasks using alternative technologies. Many of our
competitors have greater financial, operational, sales and marketing
resources, and more experience in research and development than we have. 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.

In the SNP genotyping marketplace, MassArray competes with alternative
technology concepts which differ in the areas of sample amplification,
analysis process, sample separation or SNP detection and are all based on
indirect detection of the molecule hybridization and/or labeling. Such
technologies include:

 . Gel-based fluorescent sequencing as offered by PE Corporation, Amersham
  Pharmacia Biotech, Visible Genetics, Inc. and others and primarily developed
  for DNA analysis, such as DNA sequencing;

 . Single base primer extensions and colormetric detection offered by the
  genetic bit analysis of Orchid Biocomputer Inc.;

 . Fluorescence resonance energy transfer, or FRET, offering real-time PCR-
  based fluorescent detection and incorporated in PE Corporation's TaqMan
  product line;

 . Invader and Invader Squared SNP detection, an alternative linear
  amplification technology including structure-based hybridization and enzyme
  cleavage developed by Third Wave Technologies, Inc.;

 . Hybridization methods, such as those used by Affymetrix, Inc., Hyseq, Inc.,
  Nanogen, Inc., Protogene Laboratories Inc. and others with miniaturized chip
  formats and those offered by Genometrix in microtiter plate arrays; and

 . Bead-based capture technologies involving hybridization and fluorescent
  detection as developed by Illumina, Inc., which uses fiber optics, or
  Luminex Corporation, which uses flow cytometry.

The number of entities applying mass spectrometry in DNA analysis is
increasing continuously. PE Corporation and GeneTrace Systems Inc. have
implemented analysis concepts that involve direct analysis of enzymatically-
generated nucleic acid fragments by MALDI-TOF. Rapigene Inc. and Genetrace
Systems Inc. use a mass spectrometry approach that incorporates mass labels
and therefore is an indirect analysis of the molecule.

GOVERNMENT REGULATION

We are not subject to direct governmental regulation other than the laws and
regulations generally applicable to businesses in the jurisdictions in which
we operate.

SCIENTIFIC ADVISORY BOARD

We have established a scientific advisory board made up of leading scholars in
the field of mass spectrometry, molecular medicine, proteonomics and molecular
microbiology. Members of our scientific advisory board consult with us on
matters relating to the development of our products described elsewhere in
this prospectus. Members of our Scientific Advisory Board are reimbursed for
the reasonable expenses of attending meetings of the scientific advisory

EMPLOYEES

As of December 31, 1999, we employed 103 persons, of whom 31 hold PhD or MD
degrees and 18 hold other advanced degrees. Approximately 55 employees are
engaged in research and development, 13 in business development, sales and
marketing, 10 in manufacturing and 25 in intellectual property, finance and
other administrative functions. Our success will depend in large part upon our
ability to attract and retain employees. We face competition in this regard
from other companies, research and academic institutions, government entities
and other organizations. We believe that we maintain good relations with our
employees.

FACILITIES

We currently lease an approximately 31,000 square foot facility in San Diego,
California for our headquarters and as the base for marketing and product
support operations, research and development and manufacturing activities.
Under this lease we will add approximately 14,000 square feet through fiscal
2001. We will need to make improvements to the additional space to make it
suitable for our needs. The lease expires in September 2004. We also lease an
approximately 3,000 square foot facility in Sudbury, Massachusetts for product
and customer support. In addition, we lease an approximately 15,000 square
foot facility in Hamburg, Germany to support sales and distribution in Europe.
Under the terms of these leases, we presently pay rent of approximately
$53,000 per month. We believe that our current facilities will be adequate to
meet our near-term space requirements. We also believe that suitable
additional space will be available to us, when needed, on commercially
reasonable terms.

ORGANIZATION

We were incorporated in the state of Delaware in 1994.

OPTIONS
The following table shows information regarding options granted to the
executive officers listed in the summary compensation table above during the
fiscal years ended December 31, 1998 and 1999. We have not granted any stock
appreciation rights.

Each option represents the right to purchase one share of our common stock.
The options generally become vested over four years. To the extent not already
vested, some of these options may also accelerate and become exercisable in
the event of a merger in which we are not the surviving corporation or upon
the sale of substantially all of our assets. Please see "Management--Employee
benefit plans" for more details regarding these options. In the years ended
December 31, 1998 and 1999, we granted options to purchase an aggregate of 1.3
million and 1.1 million shares of common stock, respectively, to various
officers, employees, directors and consultants.

The potential realizable value at assumed annual rates of stock price
appreciation for the option term represents hypothetical gains that could be
achieved for the respective options if exercised at the end of the option
term. The 5% and 10% assumed annual rates of compounded stock price
appreciation are required by rules of the Securities and Exchange Commission
and do not represent our estimate or projection of our future common stock
prices. These amounts represent assumed rates of appreciation in the value of
our common stock from the fair market value on the date of grant. Actual
gains, if any, on stock option exercises are dependent on the future
performance of our common stock and overall stock market conditions. The
amounts reflected in the table may not necessarily be achieved.

The following table shows information at December 31, 1999 concerning the
number and value of unexercised options held by each of the executive officers
listed in the summary compensation table above. Options shown as exercisable
in the table below are immediately exercisable. However, we have rights to
repurchase shares of the common stock underlying some of these options upon
termination of the holder's employment with us. There was no public trading
market for the common stock as of December 31, 1999. Accordingly, the value of
unexercised in-the-money options listed below has been calculated on the basis
of the assumed initial public offering price of $24.00 per share, less the
applicable exercise price per share, multiplied by the number of shares
underlying such options.

EMPLOYEE BENEFIT PLANS

1999 STOCK INCENTIVE PLAN

INTRODUCTION
Our 1999 Stock Incentive Plan is intended to serve as the successor program to
our 1998 Stock Option/Stock Issuance Plan. The 1999 plan was adopted by our
board of directors on November 6, 1999 and approved by the stockholders in
November 1999. The 1999 plan will become effective at the close of this
offering. At that time, all outstanding options under our existing 1998 Stock
Option/Stock Issuance Plan will be transferred to the 1999 plan, and no
further option grants will be made under the 1998 plan. Prior to the 1998 plan
being adopted, we granted options under our 1994 Stock Plan. All options
granted under our 1994 Stock Plan were transferred to our 1998 Stock
Option/Stock Issuance Plan. The transferred options will continue to be
governed by their existing terms, unless our compensation committee decides to
extend one or more features of the 1999 plan to those options. Except as
otherwise described below, the transferred options have substantially the same
terms as will be in effect for grants made under the discretionary option
grant program of our 1999 plan.

SHARE RESERVE
We have reserved 4,750,000 shares of our common stock for issuance under our
1999 Stock Incentive Plan. This share reserve consists of the number of shares
we estimate will be carried over from our 1998 plan plus an additional 850,000
shares. The share reserve under our 1999 plan will automatically increase on
the first trading day in January each calendar year, beginning with calendar
year 2001, by an amount equal to 4% of the total number of shares of our
common stock outstanding on the last trading day of December in the prior
calendar year, but in no event will this annual increase exceed 2,000,000
shares. In addition, no participant in our 1999 plan may be granted stock
options or direct stock issuances for more than 1,000,000 shares of common
stock in total in any calendar year.

MANAGEMENT

- -------------------------------------------------------------------------------
PROGRAMS
Our 1999 plan has five separate programs:

 . the discretionary option grant program, under which eligible individuals may
  be granted options to purchase shares of our common stock at an exercise
  price not less than the fair market value of those shares on the grant date;

 . the stock issuance program, under which eligible individuals may be issued
  shares of common stock directly, upon the attainment of performance
  milestones or the completion of a specified period of service or as a bonus
  for past services;

 . the salary investment option grant program, under which our executive
  officers and other highly compensated employees may be given the opportunity
  to apply a portion of their base salary each year to the acquisition of
  special below market stock option grants;

 . the automatic option grant program, under which option grants will
  automatically be made at periodic intervals to eligible non-employee board
  members to purchase shares of common stock at an exercise price equal to the
  fair market value of those shares on the grant date; and

 . the director fee option grant program, under which our non-employee board
  members may be given the opportunity to apply a portion of any retainer fee
  otherwise payable to them in cash each year to the acquisition of special
  below market option grants.

ELIGIBILITY
The individuals eligible to participate in our 1999 plan include our officers
and other employees, our board members and any consultants we use.

ADMINISTRATION
The discretionary option grant and stock issuance programs will be
administered by our compensation committee. This committee will determine
which eligible individuals are to receive option grants or stock issuances
under those programs, the time or times when the grants or issuances are to be
made, the number of shares subject to each grant or issuance, the status of
any granted option as either an incentive stock option or a nonstatutory stock
option under the federal tax laws, the vesting schedule to be in effect for
the option grant or stock issuance and the maximum term for which any granted
option is to remain outstanding. The compensation committee will also have the
authority to select the executive officers and other highly compensated
employees who may participate in the salary investment option grant program if
the program is put into effect for one or more calendar years.

PLAN FEATURES
Our 1999 plan will include the following features:

 . the exercise price for any options granted under the plan may be paid in
  cash or in shares of our common stock valued at fair market value on the
  exercise date. The option may also be exercised through a same-day sale
  program without any cash outlay by the optionee;

 . our compensation committee will have the authority to cancel outstanding
  options under the discretionary option grant program, including any
  transferred options from our 1998 plan, in return for the grant of new
  options for the same or different number of option shares with an exercise
  price per share based upon the fair market value of our common stock on the
  new grant date; and

 . stock appreciation rights may be issued under the discretionary option grant
  program. These rights will provide the holders with the election to
  surrender their outstanding options for a payment from us equal to the fair
  market value of the shares subject to the surrendered options less the
  exercise price payable for those shares. We may make the payment in cash or
  in shares of our common stock. None of the options under our 1998 plan have
  any stock appreciation rights.

MANAGEMENT

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

CHANGE IN CONTROL
Our 1999 plan will include the following change in control provisions which
may result in the accelerated vesting of outstanding option grants and stock
issuances if:

 . we are acquired by merger or asset sale, each outstanding option under the
  discretionary option grant program which is not to be assumed by the
  successor corporation will immediately become exercisable for all the option
  shares, and all outstanding unvested shares will immediately vest, except to
  the extent our repurchase rights with respect to those shares are to be
  assigned to the successor corporation;

 . our compensation committee will have complete discretion to grant one or
  more options which will become exercisable for all the option shares in the
  event those options are assumed in the acquisition but the optionee's
  service with us or the acquiring entity is subsequently terminated. The
  vesting of any outstanding shares under our 1999 plan may be accelerated
  upon similar terms and conditions; and

 . our compensation committee may grant options and structure repurchase rights
  so that the shares subject to those options or repurchase rights will
  immediately vest in connection with a successful tender offer for more than
  50% of our outstanding voting stock or a change in the majority of our board
  through one or more contested elections. Such accelerated vesting may occur
  either at the time of such transaction or upon the subsequent termination of
  the individual's service.

SALARY INVESTMENT OPTION GRANT PROGRAM
If our compensation committee decides to put this program into effect for one
or more calendar years, each of our executive officers and other highly
compensated employees may elect to reduce his or her base salary for the
calendar year by an amount not less than $10,000 nor more than $50,000. Each
individual who makes such an election will automatically be granted, on the
first trading day in January of the calendar year for which his or her salary
reduction is to be in effect, an option to purchase that number of shares of
common stock determined by dividing the salary reduction amount by two-thirds
of the fair market value per share of our common stock on the grant date. The
option will have an exercise price per share equal to one-third of the fair
market value of the option shares on the grant date. As a result, the option
will be structured so that the fair market value of the option shares on the
grant date less the exercise price payable for those shares will be equal to
the amount of the salary reduction. The option will become exercisable in a
series of twelve equal monthly installments over the calendar year for which
the salary reduction is to be in effect.

AUTOMATIC OPTION GRANT PROGRAM
Each individual who first becomes a non-employee board member at any time
after the effective date of this offering will receive an option grant to
purchase 15,000 shares of our common stock on the date such individual joins
the board. In addition, on the date of each annual stockholders meeting held
after the effective date of this offering, each non-employee board member who
is to continue to serve as a non-employee board member, including each of our
current non-employee board members, will automatically be granted an option to
purchase 3,000 shares of our common stock, provided such individual has served
on the board for at least six months.

Each automatic grant will have an exercise price per share equal to the fair
market value per share of our common stock on the grant date and will have a
term of 10 years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid
per share, any shares purchased under the option which are not vested at the
time of the optionee's cessation of board service. The shares subject to each
initial 15,000 share automatic option grant will vest in a series of three
successive annual

- -------------------------------------------------------------------------------
                                                                             57

MANAGEMENT

- -------------------------------------------------------------------------------
installments upon the optionee's completion of each year of board service over
the three year period measured from the grant date. The shares subject to each
3,000 share annual option grant will vest upon the optionee's completion of
one year of board service measured from the grant date. The shares subject to
each option will immediately vest in full upon various changes in control or
ownership or upon the optionee's death or disability while a board member.

DIRECTOR FEE OPTION GRANT PROGRAM
If this program is put into effect in the future, then each non-employee board
member may elect to apply all or a portion of any cash retainer fee for the
year to the acquisition of a below-market option grant. The option grant will
automatically be made on the first trading day in January in the year for
which the non-employee board member would otherwise be paid the cash retainer
fee in the absence of his or her election. The option will have an exercise
price per share equal to one-third of the fair market value of the option
shares on the grant date, and the number of shares subject to the option will
be determined by dividing the amount of the retainer fee applied to the
program by two-thirds of the fair market value per share of our common stock
on the grant date. As a result, the option will be structured so that the fair
market value of the option shares on the grant date less the exercise price
payable for those shares will be equal to the portion of the retainer fee
applied to that option. The option will become exercisable in a series of
twelve equal monthly installments over the calendar year for which the
election is in effect. However, the option will become immediately exercisable
for all the option shares upon the death or disability of the optionee while
serving as a board member. Currently our directors do not have any cash
retainer fee.

ADDITIONAL PLAN FEATURES
Our 1999 plan will also have the following features:

 . Outstanding options under the salary investment and director fee option
  grant programs will immediately vest if we are acquired by a merger or asset
  sale or if there is a successful tender offer for more than 50% of our
  outstanding voting stock or a change in the majority of our board through
  one or more contested elections.

 . Limited stock appreciation rights will automatically be included as part of
  each grant made under the salary investment option grant program and the
  automatic and director fee option grant programs, and these rights may also
  be granted to one or more officers as part of their option grants under the
  discretionary option grant program. Options with this feature may be
  surrendered to us upon the successful completion of a hostile tender offer
  for more than 50% of our outstanding voting stock. In return for the
  surrendered option, the optionee will be entitled to a cash distribution
  from us in an amount per surrendered option share based upon the highest
  price per share of our common stock paid in that tender offer.

 . Our board of directors may amend or modify our 1999 plan at any time,
  subject to any required stockholder approval. Our 1999 plan will terminate
  no later than November 6, 2009.

1999 EMPLOYEE STOCK PURCHASE PLAN

INTRODUCTION
Our 1999 Employee Stock Purchase Plan was adopted by our board of directors on
November 6, 1999 and approved by our stockholders in November 1999. The plan
will become effective immediately upon the signing of the underwriting
agreement for this offering. The plan is designed to allow our eligible
employees and the eligible employees of our participating subsidiaries to
purchase shares of common stock, at semi-annual intervals, with their
accumulated payroll deductions.


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

<PAGE>

MANAGEMENT

- -------------------------------------------------------------------------------
SHARE RESERVE
We have reserved 250,000 shares of our common stock for issuance under our
1999 Employee Stock Purchase Plan. The reserve will automatically increase on
the first trading day in January each calendar year, beginning in calendar
year 2001, by an amount equal to 1% of the total number of outstanding shares
of our common stock on the last trading day in December in the prior calendar
year. In no event will any such annual increase exceed 500,000 shares.

OFFERING PERIODS
Our 1999 Employee Stock Purchase Plan will have a series of concurrent
offering periods, each with a maximum duration of 24 months. The initial
offering period will start on the date the underwriting agreement for the
offering covered is signed and will end on the last business day in January
2002. Additional offering periods of up to 24 months duration will begin on
the first day of February and August each year. However, no employee may
participate in more than one offering period at a time.

ELIGIBILITY
Individuals scheduled to work more than 20 hours per week for more than five
calendar months per year are eligible to participate in the plan and may join
the plan on the start date of any offering period.

PAYROLL DEDUCTIONS
A participant may contribute up to 15% of his or her base salary through
payroll deductions, and the accumulated deductions will be applied to the
purchase of shares on each semi-annual purchase date. The purchase price per
share in effect for each participant will be equal to 85% of the fair market
value per share on the start date of the offering period in which he or she is
participating or, if lower, 85% of the fair market value per share on the
semi-annual purchase date. Semi-annual purchase dates will occur on the last
business day of January and July each year. However, a participant may not
purchase more than 1,000 shares on any purchase date, and not more than
62,500 shares may be purchased in total by all participants on any purchase
date. Our compensation committee will have the authority to change these
limitations for any subsequent offering period.

RESET FEATURE
If the fair market value per share of our common stock on any purchase date
within a particular offering period is less than the fair market value per
share on the start date of that offering period, then that offering period
will automatically terminate, and a new offering period of up to 24 months
duration will begin on the next business day. All eligible participants in the
terminated offering will be transferred to the new offering period.

CHANGE IN CONTROL
If we are acquired by merger or a sale of substantially all of our assets or
more than 50% of our voting securities, then all outstanding purchase rights
will automatically be exercised immediately prior to the effective date of the
acquisition. The purchase price in effect for each participant will be equal
to 85% of the market value per share on the start date of the particular
offering period in which he or she is participating at the time of the
acquisition or, if lower, 85% of the fair market value per share immediately
prior to the acquisition.

PLAN FEATURES
The following features will also be in effect under the plan:

 . our plan will terminate no later than the last business day of January 2010;
  and

 . our board may at any time amend, suspend or discontinue our plan; however,
  certain amendments may require stockholder approval.

INDEBTEDNESS OF MANAGEMENT

We have loaned money to some of our executive officers under the terms of
promissory notes and stock pledge agreements, whereby the executive officers
pledge shares of our common stock issued upon the exercise of options to
purchase such common stock. These loans were used by the executive officers
upon the exercise of these options to acquire the underlying shares of common
stock. Each loan is required to be repaid on the earlier of two years after
its execution or the completion of a secondary public offering by us, in which
the officer making the note is allowed to sell his shares of our common stock.
The amount outstanding at December 31, 1999 on each loan shown below

INDEMNIFICATION AGREEMENTS

We have entered into indemnification agreements with each of our directors and
officers containing provisions that may require us to indemnify them against
liabilities that may arise by reason of their status or service as directors
or officers and to advance their expenses incurred as a result of any
proceeding against them. However, we will not indemnify directors or officers
with respect to liabilities arising from willful misconduct of a culpable
nature. For more information concerning these agreements, see "Description of
securities--limitation of liabilities and indemnification matters."

CONSULTING AGREEMENT

During the period beginning when we were organized in 1994 until July 1997,
Dr. Hubert Koster worked for us as a consultant. We paid Dr. Koster $5,000 per
month until September 1996 at which time we increased his consulting
compensation to $12,500 per month, in consideration for his services to us.
Dr. Koster's consulting arrangement was terminated when he was appointed as
our President and Chief Executive Officer in 1997.

INTELLECTUAL PROPERTY ASSIGNMENTS

Since our inception, Dr. Koster has assigned several personal patents and
other intellectual property rights to us that are key in the development of
our products and technology. As partial consideration for these assignments,
we reimbursed Dr. Koster for patent application costs and prior to 1996 we
issued shares of our Series A convertible preferred stock to Dr. Koster. We
have paid no additional consideration to Dr. Koster except for those amounts
paid in connection with his employment or consulting services to us since
January 1996.

Dr. Cantor is named as an inventor on a number of patents which we have
licensed from Boston University. If we are commercially successful and are
required to make royalty payments to Boston University under our license
arrangements, Dr. Cantor could receive additional compensation from Boston
University. In addition, we fund research at Boston University; however, Dr.
Cantor receives no direct compensation from Boston University as a result of
this funding.

The descriptions of the common stock and preferred stock, as well as options

par value $0.001 per share, and 5,000,000 shares of preferred stock, par value
$0.001 per share.

of any outstanding preferred stock. Holders of common stock have no
preemptive, subscription, redemption or conversion rights. 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 common stock are subject to, and may
be materially adversely affected by, the rights of the holders of shares of
any series of preferred stock which we may designate and issue in the future.
Upon the closing of this offering, there will be no shares of preferred stock
outstanding.

REGISTRATION RIGHTS

Under the terms of an agreement with some of our stockholders, after the
closing of this offering the holders of 14,842,757 shares of common stock will
be entitled to demand the registration of their shares under the Securities
Act of 1933. The holders of 50% of such shares are entitled to demand that we
register their shares under the Securities Act of 1933 subject to limitations
described in the relevant agreement. We are not required to effect more than
two registrations for such holders pursuant to these demand registration
rights. These demand rights expire on December 21, 2001. In addition, after
the closing of this offering these holders will be entitled to piggyback
registration rights with respect to the registration of their shares of common
stock. If we propose to register any shares of common stock either for our

having piggyback rights are entitled to receive notice of the registration and
are entitled to include their shares in the registration, subject to some
limitations. Further, at any time after we become eligible to file a

shares of our common stock. These registration rights are subject to
conditions and limitations, among which is the right of the underwriters of an
offering to limit the number of shares of common stock held by security
holders with registration rights to be included in such registration. We are
generally required to bear all of the expenses of all these registrations,
including the reasonable fees of a single counsel acting on behalf of all
selling stockholders, except underwriting discounts and selling commissions.
Registration of any of the shares of our common stock held by security holders
with registration rights would result in such shares becoming freely tradable
without restriction under the Securities Act of 1933 immediately upon
effectiveness of such registration.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND OUR CERTIFI-
CATE OF INCORPORATION AND BYLAWS

We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Subject to exceptions, 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 date of the

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

<PAGE>

DESCRIPTION OF SECURITIES

- -------------------------------------------------------------------------------
transaction in which the person became an interested stockholder, unless the
interested stockholder attained such status with the approval of the board of
directors or unless the business combination is approved in a prescribed
manner. A "business combination" includes mergers, asset sales and other
transactions resulting in a financial benefit to the interested stockholder.
Subject to 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. This statute could prohibit or delay
the accomplishment of mergers or other takeover or change in control attempts
with respect to us and, accordingly, may discourage attempts to acquire us.

In addition, provisions of our certificate of incorporation and bylaws, which
will be in effect upon the closing of this offering and are summarized in the
following paragraphs, may have an anti-takeover effect and may delay, defer or
prevent a tender offer or takeover attempt that a stockholder might consider
in its best interest, including those attempts that might result in a premium
over the market price for the shares held by stockholders.

BOARD OF DIRECTORS VACANCIES

Our bylaws authorize the board of directors to fill vacant directorships or
increase the size of the board of directors. This may deter a stockholder from
removing incumbent directors and simultaneously gaining control of the board
of directors by filling the vacancies created by such removal with its own
nominees.

STAGGERED BOARD

Our bylaws provide that our board will be classified into three classes of
directors beginning at the next annual meeting of stockholders. Please see
"Management--Classes of the board" for more information regarding our
staggered board. This may inhibit a stockholder from nominating and electing
directors and gaining control of the board of directors.

STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS

Our certificate of incorporation provides that our stockholders may not take
action by written consent, and may only act at a duly called annual or special
meetings of our stockholders. Our bylaws further provide that special meetings
of our stockholders may be called only by the President, Chief Executive
Officer or Chairman of the board of directors or a majority of the board of
directors.

ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS

Our bylaws provide that stockholders seeking to bring business before our
annual meeting of stockholders, or to nominate candidates for election as
directors at our annual meeting of stockholders, must provide timely notice of
their intent in writing. To be timely, a stockholder's notice must be
delivered to, or mailed and received at, our principal executive offices not
less than 120 days before the first anniversary of the date of our notice of
annual meeting provided with respect to the previous year's annual meeting of
stockholders; provided, that if no annual meeting of stockholders was held in
the previous year or the date of the annual meeting of stockholders has been
changed to be more than 30 calendar days earlier than such anniversary, notice
by the stockholder, to be timely, must be so received a reasonable time before
the solicitation is made. Our bylaws also contain specific requirements as to
the form and content of a stockholder's notice. These provisions may inhibit
our stockholders from bringing matters before our annual meeting of
stockholders or from making nominations for directors at our annual meeting of
stockholders.

AUTHORIZED BUT UNISSUED SHARES

Our authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval, subject to
limitations imposed by the Nasdaq National Market. These additional shares may
be utilized for a variety of corporate purposes, including future public
offerings to raise additional capital, corporate acquisitions and employee
benefit plans. The existence of authorized but unissued and unreserved common
stock and preferred stock could render more difficult or discourage an attempt
to obtain control of us by means of a proxy contest, tender offer, merger or
otherwise.

Delaware law provides generally that the affirmative vote of a majority of the
shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws requires a greater percentage.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

Our certificate of incorporation provides that, except to the extent
prohibited by Delaware law, our directors shall not be personally liable to us
or our stockholders for monetary damages for any breach of fiduciary duty as
our directors. Under Delaware law, our directors have a fiduciary duty to us
which is not eliminated by this provision of the certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other
forms of nonmonetary relief will remain available. In addition, each of our
directors will continue to be subject to liability under Delaware law for
breach of the director's duty of loyalty to us for acts or omissions which are
found by a court of competent jurisdiction to be not in good faith or which
involve intentional misconduct, or knowing violations of law, for actions
leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are prohibited
by Delaware law. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws.

Section 145 of the Delaware General Corporation Law empowers a corporation to
indemnify its directors and officers and to purchase insurance with respect to
liability arising out of their capacity or status as directors and officers,
provided that this provision shall not eliminate or limit the liability of a
director for the following:

 . any breach of the director's duty of loyalty to us or our stockholders;

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

 . unlawful payments of dividends or unlawful stock purchases or redemptions;
  or

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

Delaware law provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under our bylaws, any agreement, a vote of
stockholders or otherwise. The certificate eliminates the personal liability
of directors to the fullest extent permitted by Delaware law. In addition, the
certificate provides that we may fully indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (whether civil, criminal, administrative
or investigative) by reason of the fact that such person is or was one of our
directors or officers or is or was serving at our request as a director or
officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding.

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

<PAGE>

DESCRIPTION OF SECURITIES

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

We have also entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. We
believe that these provisions and agreements are necessary to attract and
retain qualified directors and executive officers. Our bylaws also permit us
to secure insurance on behalf of any officer, director, employee or other
agent for any liability arising out of his or her actions, regardless of
whether Delaware law would permit indemnification. We have applied for
liability insurance for our officers and directors.

At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under our certificate of incorporation or otherwise. We
are not aware of any threatened litigation or proceeding that may result in a
claim for such indemnification.

TRANSFER AGENT AND REGISTRAR

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

Shares eligible for future sale

Prior to this offering, there has been no public offering for our stock. The
market price of our common stock could decline as a result of sales of a large
number of shares of our common stock in the market after this offering, or the
perception that such sales could occur. Such sales also could make it more
difficult for us to sell equity securities in the future at a time and price
that we deem appropriate. After this offering, we will have outstanding
22,601,477 shares of common stock. Of these shares, the 5,000,000 shares being
offered by us and the 67,826 shares being offered by the selling stockholders
in this offering are freely tradable. This leaves 17,536,477 shares eligible
for sale in the public market as follows:

</TABLE>

Our directors and officers and some of our stockholders who hold 15,110,424
shares in the aggregate, together with the holders of options to purchase
272,108 shares of common stock and the holders of warrants to purchase 106,503
shares of common stock, have entered into lock-up agreements under which they
have agreed that they will not sell, directly or indirectly, any shares of
common stock without the prior written consent of Warburg Dillon Read LLC for
a period of 180 days from the date of this prospectus.

In general, under Rule 144 of the Securities Act of 1933, as currently in
effect, a person or persons whose shares are required to be aggregated,
including an affiliate, who has beneficially owned shares for at least one
year is entitled to sell, within any three-month period after the date of this
prospectus, a number of shares that does not exceed the greater of 1% of the
then outstanding shares of common stock--approximately 225,000 shares
immediately after this offering--or the average weekly trading volume in our
common stock during the four calendar weeks preceding the date on which notice
of such sale is filed, subject to certain restrictions. In addition, a person
who is not deemed to have been an affiliate of ours at any time during the 90
days preceding a sale and who has beneficially owned the shares proposed to be
sold for at least two years would be entitled to sell such shares under
Rule 144(k) without regard to the requirements described above. To the extent
that shares were acquired from one of our affiliates, such person's holding
period for the purpose of effecting a sale under Rule 144 commences on the
date of transfer from the affiliate.

Following 90 days after the date of this prospectus, shares issued upon
exercise of options that we granted prior to the date of this offering will
also be available for sale in the public market pursuant to Rule 701 under the
Securities Act of 1933. Rule 701 permits resales of such shares in reliance
upon Rule 144 under the Securities Act of 1933 but without compliance with the
restrictions, including the holding-period requirement, imposed under Rule
144. As of December 27, 1999, options to purchase a total of 1,287,049 shares
of common stock were outstanding, all of which were currently exercisable, but
some of which are subject to repurchase by us. Of these 1,287,049 shares,
484,457 shares may be eligible for sale in the public market at various times
after 90 days from the date of this prospectus.

Upon the closing of this offering, we intend to file a registration statement
to register for resale the 2,385,819 shares of common stock reserved for
issuance under our stock option plans. We expect the

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

- -------------------------------------------------------------------------------
registration statement to become effective immediately upon filing. Shares
issued upon the exercise of stock options granted under our stock option plans
will be eligible for resale in the public market from time to time subject to
vesting and, in the case of certain options, the expiration of the lock-up
agreements referred to above.

Stockholders holding approximately 14,842,757 shares of common stock have the
right, subject to various conditions and limitations, to include their shares
in registration statements relating to our securities. By exercising their
registration rights and causing a large number of shares to be registered and
sold in the public market, these holders may cause the price of the common
stock to fall. In addition, any demand to include such shares in our
registration statements could have a material adverse effect on our ability to
raise needed capital. Please see "Management--Benefit plans," "Principal
stockholders," "Description of securities--Registration rights," "Shares
eligible for future sale" and "Underwriting."

an underwriting agreement concerning the shares being offered. Subject to
conditions, each underwriter has severally agreed to purchase the number of
shares indicated in the following table. Warburg Dillon Read LLC, FleetBoston
Robertson Stephens Inc. and SG Cowen Securities Corporation are the
representatives of the underwriters.

</TABLE>

If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have a 30-day option to buy from us up to an
additional 750,000 shares at the initial public offering price less the
underwriting discounts and commissions to cover these sales. If any shares are
purchased under this option, the underwriters will severally purchase shares
in approximately the same proportion as set forth in the table above.

The following table shows the per share and total underwriting discounts and
commissions we will pay to the underwriters. These amounts are shown assuming
both no exercise and full exercise of the underwriters' option to purchase up
to an additional 750,000 shares.

We estimate that the total expenses of the offering payable by us, excluding
underwriting discounts and commissions, will be approximately $        .

Shares sold by the underwriters to the public will initially be offered at the
initial public offering price set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a
discount of up to $         per share from the initial public offering price.
Any of these securities dealers may resell any shares purchased from the
underwriters to other brokers or dealers at a discount of up to $        per
share from the initial public offering price. If all the shares are not sold
at the initial public offering price, the representatives may change the
offering price and the other selling terms.

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

Sequenom, its directors, officers and certain of its stockholders have agreed
with the underwriters not to offer, sell, contract to sell, hedge or otherwise
dispose of, directly or indirectly, or file with the SEC a registration
statement under the Securities Act relating to, any of its common stock or
securities convertible into or exchangeable for shares of common stock during
the period from the date of this prospectus continuing through the date 180
days after the date of this prospectus, without the prior written consent of
Warburg Dillon Read LLC. This agreement does not apply to any securities
issued under existing employee benefit plans.

UNDERWRITING

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

The underwriters have reserved for sale, at the initial public offering price,
up to        shares of our common stock being offered for sale to our
customers and business partners. At the discretion of our management, other
parties, including our employees, may participate in the reserved shares
program. The number of shares available for sale to the general public in the
offering will be reduced to the extent these persons purchase 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.

Pursuant to a settlement and release relating to a consulting agreement for
advisory services rendered in connection with this offering between ACXIT
Capital Management GmbH and Value Management & Research AG and Sequenom,
Sequenom will pay those entities an aggregate amount of approximately DEM
789,000 or approximately $410,000. The National Association of Securities
Dealers, Inc. has determined this amount to be underwriting compensation.
These consultants are deemed to be underwriters for purposes of this offering.

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

 . the information set forth in this prospectus and otherwise available to the
  representatives;

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

 . the ability of our management;

 . our prospects for future earnings, the present state of our development, and
  our current financial position;

 . 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.

In connection with the offering, the underwriters may purchase and sell shares
of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering.
Stabilizing transactions consist of bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the common stock
while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular
underwriter repays to the underwriters a portion of the underwriting discount
received by it because the representatives have repurchased shares sold by or
for the account of that underwriter in stabilizing or short covering
transactions.

These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by
the underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

We have agreed to indemnify the several underwriters against some liabilities,
including liabilities under the Securities Act of 1933 and to contribute to
payments that the underwriters may be required to make in respect thereof.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors
Sequenom, Inc.

We have audited the accompanying consolidated balance sheets of Sequenom, Inc.
(a development stage company) as of December 31, 1997 and 1998 and September
30, 1999 and the related consolidated statements of operations, stockholders'
equity (deficit), and cash flows for each of the three years in the period
ended December 31, 1998, the nine month period ended September 30, 1999 and
the period from February 14, 1994 (inception) to September 30, 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 consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated 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 Sequenom,
Inc. (a development stage company) at December 31, 1997 and 1998 and September
30, 1999, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 1998, the nine month period ended
September 30, 1999 and the period from February 14, 1994 (inception) to
September 30, 1999, in conformity with generally accepted accounting
principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF THE BUSINESS
Sequenom, Inc. (the "Company") was incorporated on February 14, 1994 in the
State of Delaware. Since inception, the Company has been primarily involved in
the research and development of high definition DNA analysis tools for
industrial biomedical and life science applications, and has not yet generated
revenues from its planned commercial operations. Accordingly, through the date
of these financial statements, the Company is considered to be a development
stage company.

Since inception, the Company has incurred significant losses and, as of
September 30, 1999, has an accumulated deficit of $37.1 million. Revenues to
date have been solely from research grants. The Company began placing
MassArray systems at beta sites and pre-launch partners in July 1999.
Information received from these sites is being used to optimize product
offerings. The Company expects to generate revenue from the commercial launch
of its MassArray system in the first quarter of 2000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF CONSOLIDATION
The accompanying consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiary, Sequenom GmbH. All significant
intercompany transactions have been eliminated in consolidation.

CASH AND CASH EQUIVALENTS
Cash equivalents consist of highly liquid investments with original maturities
when purchased of less than three months.

SHORT-TERM INVESTMENTS AND CONCENTRATION OF CREDIT RISK
In accordance with Statement of Financial Accounting Standards ("SFAS") No.
115, Accounting for Certain Investments in Debt and Equity Securities, the
Company's investment securities are classified as available-for-sale and
unrealized holding gains or losses are included in comprehensive income
(loss.) Realized gains or losses, calculated based on the specific
identification method, were not material for the years ended December 31,
1996, 1997 and 1998, or the nine-month period ended September 30, 1999.

At December 31, 1998, short-term investments consisted of the following:

</TABLE>

Approximately 76% and 24% of these securities mature within one and two years
of September 30, 1999, respectively.

INVENTORIES
Inventories consist principally of raw materials and are stated at the lower
of cost or market. Cost is determined by the first-in, first-out (FIFO)
method.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS
Equipment is stated at cost and depreciated using the straight-line method
over the estimated useful lives of the assets, generally 3 to 5 years, or the
lease term, whichever is shorter. Leasehold improvements are amortized using
the straight-line method over the estimated useful life of the improvement or
the remaining term of the lease, whichever is shorter.

SOFTWARE COSTS
Purchased software is capitalized at cost and amortized over the estimated
useful life, generally three years. Software developed for use in the
Company's products is expensed as incurred until both (i) technological
feasibility for the software has been established, and (ii) all research and
development activities for the other components of the system have been
completed. The Company believes this will occur after the Company has received
evaluations from the beta sites and has concluded any resulting modifications
to the products. Expenditures to date have been classified as research and
development expense.

IMPAIRMENT OF LONG-LIVED ASSETS
In accordance with SFAS No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed of, if indicators of
impairment exist, the Company assesses the recoverability of the affected
long-lived assets by determining whether the carrying value of such assets can
be recovered through undiscounted future operating cash flows. If impairment
is indicated, the Company measures the amount of such impairment by comparing
the carrying value of the asset to the present value of the expected future
cash flows associated with the use of the asset. While the Company's current
and historical operating and cash flow losses are indicators of impairment,
the Company believes the future cash flows to be received from the long-lived
assets will exceed the assets' carrying value, and accordingly the Company has
not recognized any impairment losses through September 30, 1999.

FAIR VALUE OF FINANCIAL INSTRUMENTS
Financial instruments, including cash and cash equivalents, accounts
receivable, accounts payable, and accrued liabilities are carried at cost,
which management believes approximates fair value because of the short-term
maturity of these instruments.

The long-term debt and related accrued interest is not scheduled to be repaid
until 2005 and 2007. However, in connection with this offering, the Company
intends to extinguish the aggregate of $5,446,000 in long-term debt and
$930,625 in accrued interest through the issuance of 296,900 shares of common
stock (with a fair value of $7,125,600 at an assumed initial public offering
price of $24.00 per share) and cash of approximately $3,267,000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


REVENUE RECOGNITION
Grant revenue is recorded as the research expenses relating to the grants are
incurred, provided that the amounts received are not refundable if the
research is not successful. Amounts received that are refundable if the
research is not successful would be recorded as deferred revenue and
recognized as revenue upon the grantor's acceptance of the success of the
research results.

The Company's product shipments through September 30, 1999 have been under
arrangements whereby the customer is performing beta testing on the MassArray
product and may elect to purchase the product following the completion of an
evaluation period. Revenue under these arrangements will be recognized upon
the completion of the evaluation period and upon the customer's definitive
acceptance of the product. Certain of these arrangements require the customer
to make one or more payments during the testing and evaluation period. Amounts
received under these arrangements ($100,000 at September 30, 1999) are
recorded as customer advances, which are included in accounts payable and
accrued expenses in the accompanying balance sheet.

RESEARCH AND DEVELOPMENT COSTS
Research and development costs are expensed in the period incurred.

INCOME TAXES
In accordance with SFAS No. 109, Accounting for Income Taxes, a deferred tax
asset or liability is determined based on the difference between the financial
statement and tax basis of assets and liabilities as measured by the enacted
tax rates which will be in effect when these differences reverse. The Company
provides a valuation allowance against net deferred tax assets unless, based
upon the available evidence, it is more likely than not that the deferred tax
assets will be realized.

PATENT COSTS
Costs related to filing and pursuing patent applications are expensed as
incurred as recoverability of such expenditures is uncertain.

FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS
The financial statements of the Company's German subsidiary are measured using
the German Deutsche Mark (DEM) as the functional currency. Assets and
liabilities of this subsidiary are translated at the rates of exchange at the
balance sheet date. Income and expense items are translated at the average
daily rate of exchange during the reporting period. The resulting translation
adjustments are included as a separate component of other comprehensive income
(loss). Transactions denominated in currencies other than the local currency
are recorded based on exchange rates at the time such transactions arise.
Subsequent changes in exchange rates result in transaction gains and losses
which are reflected in income as unrealized (based on period-end translations)
or realized upon settlement of the transactions.

STOCK-BASED COMPENSATION
As permitted by SFAS No. 123, Accounting for Stock-Based Compensation, the
Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees, ("APB 25") and related
Interpretations in accounting for stock-based employee compensation. Under APB
25, if the exercise price of the Company's employee and director stock options
equals or exceeds the estimated fair value of the underlying stock on the date
of grant, no compensation expense is recognized.

- -------------------------------------------------------------------------------
F-10
<PAGE>

SEQUENOM, INC. (A DEVELOPMENT STAGE COMPANY)

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

When the exercise price of the employee or director stock options is less than
the fair value of the underlying stock on the grant date, the Company records
deferred compensation for the difference and amortizes this amount to expense
in accordance with FASB Interpretation No. 28, or FIN 28, over the vesting
period of the options. Options or stock awards issued to non-employees are
recorded at their fair value as determined in accordance with SFAS No. 123 and
recognized over the related service period.

COMPREHENSIVE INCOME (LOSS)
As of January 1, 1998, the Company adopted SFAS No. 130, Reporting
Comprehensive Income. SFAS No. 130 requires unrealized gains or losses on the
Company's available-for-sale securities and foreign currency translation
adjustments, which prior to adoption were reported separately in stockholders'
equity, to be included in other comprehensive income (loss).

SEGMENT REPORTING
The Company adopted SFAS No. 131, Disclosures About Segments of an Enterprise
and Related Information, during 1998. SFAS No. 131 requires the use of a
management approach in identifying segments of an enterprise. Management has
determined that the Company operates in one business segment.

INTERIM FINANCIAL DATA
The consolidated statements of operations and cash flows for the nine months
ended September 30, 1998 are unaudited. The unaudited consolidated financial
statements have been prepared on the same basis as the audited consolidated
financial statements and, in the opinion of management, include all
adjustments, consisting of only normal recurring adjustments, necessary to
state fairly therein, in accordance with generally accepted accounting
principles.

NET LOSS PER SHARE
In accordance with SFAS No. 128, Earnings Per Share, and SEC Staff Accounting
Bulletin (or SAB) No. 98, basic net income (loss) per share is computed by
dividing the net income (loss) for the period by the weighted average number
of common shares outstanding during the period. Diluted net income (loss) per
share is computed by dividing the net income (loss) for the period by the
weighted average number of common and common equivalent shares outstanding
during the period. Potentially dilutive securities composed of incremental
common shares issuable upon the exercise of stock options and warrants, and
common shares issuable on conversion of preferred stock, were excluded from
historical diluted loss per share because of their anti-dilutive effect.

Under the provisions of SAB No. 98, common shares issued for nominal
consideration, if any, would be included in the per share calculations as if
they were outstanding for all periods presented. No common shares have been
issued for nominal consideration.

Pro forma net loss per share has been computed as described above and also
gives effect to common equivalent shares arising from preferred stock and
long-term debt that will automatically convert upon the closing of the initial
public offering contemplated by this prospectus (using the as-if converted
method from the original date of issuance) and reflects the elimination of
interest expense on the debt to be converted.

UNAUDITED PRO FORMA BALANCE SHEET INFORMATION
The unaudited pro forma balance sheet information at September 30, 1999
reflects the conversion of the convertible preferred stock and convertible
long-term debt into 14,842,757 and 272,108 shares of

common stock, respectively, including the related recognition of
(i) $4,244,884 of interest expense for the beneficial conversion of the debt,
and (ii) the recognition of $147,600 of related foreign translation gains on
such debt from October 1, 1999 through December 27, 1999. The pro forma
balance sheet information does not reflect (i) the issuance of 1,523,451
shares of common stock from October 1, 1999 through December 27, 1999 pursuant
to the exercise of stock options, and the related issuance of loans to certain
executives of $1,545,185, resulting in a net decrease in cash of $66,993, or
(ii) $2,212,650 of additional deferred compensation recorded from October 1,
1999 through December 27, 1999.

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECLASSIFICATIONS
Certain amounts in the prior year financial statements have been reclassified
to conform to current year presentation.

NEW ACCOUNTING PRONOUNCEMENTS
The Company expects to adopt SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, effective January 1, 2001. SFAS No. 133
will require the Company to recognize all derivatives on the balance sheet at
fair value. The Company does not anticipate that the adoption of the SFAS
No. 133 will have a significant effect on its results of operations or
financial position.

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

Total depreciation and amortization expense amounted to $314,195, $351,173 and
$961,051 for the years ended December 31, 1996, 1997 and 1998, respectively,
and $1,285,789 for the nine month period ended September 30, 1999.
Depreciation expense for the period from inception (February 14, 1994) through
September 30, 1999 was $3,060,173.

4. LONG-TERM DEBT
In 1995, the Company entered into agreements with Technologie Beteiligungs
Gesellschaft ("TBG") for two unsecured loans, one for DEM1 million
(approximately $700,000) and the other for DEM3 million

- -------------------------------------------------------------------------------
F-12
<PAGE>

SEQUENOM, INC. (A DEVELOPMENT STAGE COMPANY)

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(approximately $2.0 million). In 1997, the Company's subsidiary entered into
another agreement with the same German bank for an additional unsecured loan
of DEM2 million (approximately $1.2 million).

Interest is payable semi-annually on the loans. The 1995 loans began accruing
interest at 6% per annum commencing March 31, 1997 and payments commenced in
June 1997. The effective nominal interest rate over the life of the 1995 loans
is 4.8%. The 1997 loan bears interest at 7% and payments commenced in 1998.
The subsidiary is also required to pay additional interest equal to 9% of the
subsidiary's annual profits, to the extent that such profits exceed DEM100,000
per year (the subsidiary has not earned any such profits through September 30,
1999). The combined annual interest rate (nominal interest and additional
interest) may not exceed 7% per year through December 31, 2000. Commencing
January 1, 2001 and January 1, 2003, any amounts still outstanding will accrue
additional interest at 6% and 7% per annum for the 1995 loans and 1997 loan,
respectively.

In addition, at the end of the loan term (earlier of repayment or December 31,
2005 and December 31, 2007 for the 1995 loans and 1997 loan, respectively),
the subsidiary is obligated to pay terminal interest equal to 25%, 30% and 35%
of the amounts loaned under the DEM1 million, DEM3 million and DEM2 million
agreements, respectively, estimated to be approximately $1.2 million at the
end of the loan term. The Company has accrued interest in the amount of
$930,625 relating to the terminal interest representing approximately 75% of
the terminal interest to be paid at the end of the loan term. The Company's
accrual has been recorded on a straight-line basis, based upon the assumption
that the entire success fee would be paid in 2000, when the Company has been
expecting it would be able to repay the debt. The bank may elect to forego
collection of such amounts in certain situations. In December 1999, TBG agreed
to accept shares of the Company's common stock with an aggregate value of
$595,000, contingent upon completion of this offering, in full satisfaction of
the Company's obligation for interest payable to TBG. Assuming completion of
the initial public offering, the Company's ultimate interest cost will be
$595,000. The difference between the ultimate interest cost and accrued
interest liability will be recorded as a reduction of, interest expense upon
completion of the offering.

Under certain conditions, the Company may exercise a put option to sell its
shares of capital stock in the subsidiary to TBG for an amount equal to 50% of
the Company's equity contribution to the subsidiary pursuant to the DEM3
million loan. Through December 31, 1998, the Company had made capital
contributions to the subsidiary under the DEM3 million loan agreement of DEM3
million; therefore, the potential amount recoverable under this put option was
approximately DEM1.5 million at December 31, 1998. If the Company exercises
such put option, then the Series B Preferred Stockholders have a right to
demand redemption of their Series B Preferred Stock in the amount of $1.50 per
share. At the present time, the Company has no intention of exercising the put
option.

In January 1998, the Company entered into an agreement with TBG for debt of
DEM4 million (approximately $2.3 million) which is convertible into Common
Stock. Interest is payable at 6% of the subsidiary's annual profits. However,
the combined annual interest rate on all loans granted by TBG may not exceed
9% of the subsidiary's annual profits or 7% of the principal outstanding. The
Company may call for conversion in the event of a triggering event, as defined
in the agreement (generally a change in control or an initial public
offering). TBG may call for conversion at any time. The conversion ratio is
calculated as the arithmetic mean between $3.15 per share and a current
valuation of the Common Stock at the time of conversion, not to exceed $8.40
per share. The loan must be repaid by December 31, 2007, if not previously

amount of such charge would be approximately $4,244,884.

In 1999, the Company established a $5 million revolving line of credit with a
bank. The Company may borrow under this agreement through June 2000. Payments
of principal and interest would be made over a 48 month period, commencing
October 31, 2001. Payments prior to that date would consist of interest only.
Borrowings bear interest at LIBOR plus 1.75%. Any amounts borrowed will be
secured by short-term investments maintained at the bank. No borrowings had
been made under this agreement as of September 30, 1999.

Each share of Preferred Stock is convertible into one share of Common Stock at
the option of the holder. In addition, each share of Preferred Stock will
automatically convert to Common Stock upon the closing of the initial public
offering contemplated by this prospectus. A particular series of Preferred
Stock may be converted upon at least a two-thirds vote of the related holders
of such series of Preferred Stock.

No dividends shall be declared or paid to the holders of Series A Preferred
Stock or Common Stock unless the holders of Series B, Series C and Series D
Preferred Stock have been paid in full for all of the dividends to which they
are entitled. No dividends can be declared or paid to the holders of Series A
Preferred Stock or Common Stock at a rate greater than the rate paid to the
holders of Series B and Series C Preferred Stock.

The Series D Preferred Stock has preference as to the assets of the Company
upon liquidation over all other classes of capital stock. In liquidation, the
holders of Series A, Series B, Series C, and Series D Preferred Stock are
entitled to the greater of (i) $0.50, $1.50, $3.15 or $6.50 per share of
Series A, Series B, Series C, or Series D Preferred Stock, respectively
(subject to certain adjustments), plus declared but unpaid dividends, or (ii)
the amount per share of the Series D Preferred Stock as would have been
payable had all shares been converted to Common Stock immediately prior to a
liquidation event, plus declared but unpaid dividends. If the assets of the
Company are insufficient to permit payment in full, the entire assets of the
Company available for distribution will be distributed ratably first among the
holders of the Series D Preferred Stock and then the Series C, Series B,
Series A and Common Stock, respectively.

The holders of Series B Preferred Stock have redemption rights under certain
limited conditions as discussed in Note 4.

In February 1998, a German bank purchased 2,700 shares or approximately 5% of
Sequenom GmbH common stock for DM3 million (approximately $1.7 million). The
German bank's ownership interest in the subsidiary was convertible, at the
option of the Company, into Series C Preferred Stock. Later in 1998, the
Company effected the conversion of the minority interest into 540,000 shares
of Series C Preferred Stock at $3.15 per share. Due to the Company's ability
and intention to convert the minority interest, which existed from the date of
the original transaction, the Company accounted for the transaction as a sale
of Series C Preferred Stock and has not reflected any minority interest in its
losses during the time the German bank held the 5% minority interest.

WARRANTS
In 1994, the Company entered into a $1 million equipment lease. Under the
terms of this agreement, the Company issued warrants to purchase 70,000 shares
of Series A Preferred Stock at an exercise price of $0.50 per share. In
connection with those warrants, the Company recorded $18,000 of additional
interest expense.

In connection with the Series C Preferred Stock issued in May 1997, the
Company issued warrants to purchase 106,503 shares of Series C Preferred Stock
at an exercise price of $3.15 per share.

NOTES RECEIVABLE
In 1999, the Board of Directors authorized the issuance of approximately $3.0
million in loans to executive officers, related to the exercise of their stock
options. The notes are full recourse and are also secured by the underlying
stock. The notes bear interest at the applicable federal rate in existence
when the notes were made (approximately 6%). The principal amount of the notes
and the related interest are required to be repaid on the earlier of two years
from the origination date of the loans or in the event of a secondary public
offering, if the executive officers making the note are allowed to sell their
stock. An aggregate of $511,281 of such loans were issued as of September 30,
1999. An additional $1,545,185 of such loans were issued from October 1, 1999
through December 27, 1999 in connection with the exercise of options to
purchase 1,523,451 shares of common stock, which options had been outstanding
as of September 30, 1999. The remainder of the loans are expected to be issued
through early 2000.

STOCK COMPENSATION PLANS
In December 1998, the Company adopted the 1998 Stock Option/Stock Issuance
Plan ("1998 Plan"). The Plan provides for the grant to directors, employees
and consultants of options to purchase Common Stock. The Plan also provides
for the issuance of shares of Common Stock, subject to the Company's right to
repurchase the shares at the original purchase price in the event the employee
terminates prior to vesting. Prior to the 1998 Plan, the Company granted
options under the 1994 Stock Plan ("1994 Plan"). All options previously
granted under the 1994 Plan were transferred to the 1998 Plan in 1999. The
number of shares of Common Stock issuable under the plans was 1,700,000 and
2,700,000 in 1997 and 1998, respectively. At September 30, 1999 the number of
shares issuable under the 1998 Plan was 3,400,000. In October 1999 the number
of shares issuable under the 1998 plan was increased to 3,900,000. Options
granted under the 1998 Plan generally vest over a four-year period.

In November 1999, the Company adopted the Stock Incentive Plan ("the 1999
Plan"). The 1999 Plan provides for the grant of 4,750,000 shares of common
stock, which consists of the number of shares

estimated to carryover from the 1998 Plan, plus an increase of approximately
850,000 shares. Beginning in 2001, the amount of authorized shares available
under the 1999 Plan will automatically increase each January 1st by an amount
equal to 4% of the outstanding common stock on the prior December 31st,
subject to an annual increase limitation of 2,000,000 shares. Officers,
employees, board members and consultants are eligible to participate in the
1999 Plan. To date, no options have been granted under the 1999 Plan.

In November 1999, the Company adopted the 1999 Employee Stock Purchase Plan
("1999 ESPP"). The Company has reserved 250,000 shares of common stock for
issuance under the 1999 ESPP. Beginning in 2001, the amount of authorized
shares available under the 1999 ESPP will automatically increase each January
1st by an amount equal to 1% of the outstanding common stock on the prior
December 31st, subject to an annual increase limitation of 500,000. The 1999
ESPP will have a series of concurrent offering periods, each with a maximum
duration of 24 months, however, no employee may participate in more than one
offering period at a time.

</TABLE>

The fair value of these options was estimated at the date of grant using the
minimum value pricing model with the following weighted average assumptions
for 1996, 1997 and 1998 and for the nine months ended September 30, 1999:
risk-free interest rate of 5%, 6%, 6%, 6%; dividend yield of 0%; and a
weighted-average life of the options of four years.

The minimum value pricing model is similar to the Black-Scholes option
valuation model which was developed for use in estimating the fair value of
traded options which have no vesting restrictions and are fully transferable,
except that it excludes the factor for volatility. In addition, option
valuation models require the input of highly subjective assumptions. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of its employee stock options.

DEFERRED COMPENSATION
The Company has recorded deferred compensation totalling $2,420,150 in
December 1998 and $1,689,662 in the nine months ended September 30, 1999 in
connection with the grants of stock options to employees. In addition, the
Company recorded deferred compensation of $1,672,500 in July 1999 related to a
remeasurement of certain options originally granted to an officer in 1997.
Amortization of deferred compensation totalled $3,615,150 during the nine
months ended September 30, 1999.

In October 1999, the Company granted options to purchase 335,250 shares of
stock at $3.00 per share and recorded additional deferred compensation of
$2,212,650. In January 2000, the Company granted options to purchase 76,000
shares of stock at $3.00 per share and expects to record additional deferred
compensation of approximately $1.6 million.

CONSULTING ARRANGEMENT RELATED TO INITIAL PUBLIC OFFERING

In March 1999, the Company engaged two German consulting firms to assist the
Company in completing an initial public offering (IPO) of its common stock.
The Company agreed to pay the consulting firms an aggregate amount of
DEM150,000, or approximately $78,000, plus a percentage of the amount of
capital raised attributable to their efforts. The Company also offered and
committed to sell the firms an aggregate of DEM3 million, or approximately
$1,560,000, of freely tradeable common shares, for cash, at the IPO price in
conjunction with the completion of an IPO.

In January 2000, the Company was advised that its March 1999 offer and
commitment to sell the shares may have been in violation of Section 5 of the
Securities Act of 1933. Such a violation would provide the consulting firms
with a "put right" through January 2001 pursuant to which they could demand
that

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

the Company repurchase their shares at the original purchase price (i.e. the
initial public offering price). In January 2000, the consulting firms signed
an agreement waiving any "put right" to which they otherwise would have been
entitled and assigning their stock purchase rights to third parties. The
Company agreed to register such shares with the Registration Statement of
which this Prospectus forms a part. The consulting firms also agreed that the
total advisory fee due to them under the original agreement would be
DEM789,000, or approximately $410,000.

The Company intends to net the $410,000 advisory fee against the proceeds of
the offering, as the Company considers the fee to be a specific incremental
cost directly attributable to the offering. The Company expects the third
party assignees designated by the consulting firms will purchase an aggregate
of approximately 65,000 shares, assuming an initial public offering price of
$24.00 per share, immediately prior to the completion of this offering.
Despite the signing of the waiver, the consulting firms may still attempt to
exercise the "put right." In this event, if the Company is compelled to
repurchase their shares, the Company will record the excess of the repurchase
price over the then-current fair market value of the stock as a general and
administrative expense.

6. INCOME TAXES
Deferred income taxes reflect the net effects of temporary differences between
the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets are shown below. A valuation allowance of
$15,091,000 has been recorded as realization of such assets is uncertain.

</TABLE>

At September 30, 1999, the Company has federal and state tax net operating
loss carryforwards of approximately $24,800,000 and $13,100,000, respectively.
The difference between the federal and state tax loss carryforwards is
attributable to the capitalization of research and development expenses for
state tax purposes. The federal tax loss carryforwards will begin to expire in
2008, unless previously utilized.

Approximately $278,000 of the state tax loss carryforwards expired in 1998,
and the state tax loss carryforwards will continue to expire in 1999 unless
previously utilized. The Company also has German net operating loss
carryforwards of approximately $7,200,000, which may be carried forward
indefinitely. The Company also has federal and state research and development
tax credit carryforwards of approximately $410,000 and $200,000, respectively,
which will begin to expire in 2011 unless previously utilized.

Pursuant to Internal Revenue Code Sections 382 and 383, use of the Company's
net operating loss and credit carryforwards may be limited due to a cumulative
change in ownership of more than 50% which occurred in January 1998, as a
result of the issuance of Series C Preferred Stock, and which is anticipated
to occur with the offering. However, the Company does not believe these
limitations will materially impact the use of the net operating loss and
credit carryforwards.

The Company leases facilities in both the United States and Germany. In
September 1999, the Company amended its lease of office and research
development space to extend through September 2004. Prior to that date, the
Company had been subject to a short-term lease agreement that commenced in
October 1996. The Company's subsidiary entered into a lease of office and
research and development space in 1995 that extends through June 2001. Total
rent expense under these leases was approximately $102,000 in 1996, $250,000
in 1997, $446,000 in 1998, and $411,000 for the nine month period ended
September 30, 1999. Total rent expense under these leases was approximately
$1,154,000 for the period from February 14, 1994 (inception) to September 30,
1999.

During 1998, the Company entered into a master equipment lease agreement
providing for borrowings up to $2,100,000. Under the agreement, the lessor
will purchase equipment that the Company will lease for a 42-month period. At
September 30, 1999, the Company had borrowed the full amount available under
the agreement.

Property under capital leases is included in equipment and leasehold
improvements, as follows:

in 1996 from the City/State of Hamburg, is for DEM 800,000 (approximately
$475,000). This grant reimburses the subsidiary for the cost of certain
equipment to be used in a three-year research project. If the equipment is not
used for the grant's express purpose the equipment must be relinquished to the
City/State of Hamburg. Through December 31, 1998, approximately DEM 704,000
(approximately $420,000) of such equipment had been purchased under the grant
program and was being used for the grant's express purpose. The Company has

expected to be expended or received related to this grant.

The second grant, also received in 1996, is from the German Federal Ministry
of Research and Development and amounts to DEM 2.2 million (approximately $1.3
million). This grant reimburses the Company for certain materials, personnel,
travel and development costs. Through December 31, 1998, approximately DEM 2.1
million (approximately $1.2 million) had been expended and recovered under
this grant program. The Company has collected such amount from the grantor

Selling stockholders

The following table shows the number of shares owned by each of the selling
stockholders. This registration statement also shall cover any additional
shares of common stock which become issuable to the selling stockholders in
connection with the 67,826 shares registered for sale under this prospectus by
reason of any stock dividend, stock split, recapitalization or other similar
transaction effected without the receipt of consideration which results in an
increase in the number of our outstanding shares of common stock.

Although neither of the selling stockholders has had a material relationship
with us within the past three years, ALPHA Beteiligungsverwaltungs GbR is
associated with AXCIT Capital Mgmt. GmbH and Halford Enterprises Limited is
associated with Value Management & Research AG. Beginning in March 1999, we
had a consulting agreement with ACXIT Capital Mgmt. GmbH and Value Management
& Research AG. This agreement provided that these two companies would provide
advice and services to us in connection with this offering. We are selling to
ALPHA Beteiligungsverwaltungs GbR and Halford Enterprises Limited up to 67,826
shares as part of a settlement and full payment of the fees payable under the
agreement with AXCIT Capital Mgmt. GmbH and Value Management & Research AG for
these services.

Any estimate that we give regarding the number of shares that will be held by
the selling stockholders after completion of this offering may prove to be
inaccurate because the selling stockholders may offer all or some of the
shares they hold and because there currently are no agreements, arrangements
or understandings with respect to the sale of any of the shares. The shares
offered by this prospectus may be offered from time to time by the selling
stockholders named below. Unless otherwise indicated, each person has sole
power to invest and vote the shares listed in the table, subject to community
property laws, where applicable. For purposes of this table, a person or group
of persons is deemed to have "beneficial ownership" of any shares which that
person has the right to acquire within 60 days. Percentage ownership is based
on 17,601,477 shares of our common stock outstanding on December 27, 1999. For
purposes of computing the percentage of outstanding shares held by each person
or group of persons named below, any security which such person or group of
persons has the right to acquire within 60 days is deemed to be outstanding
for the purpose of computing the percentage ownership for such person or
persons, but is not deemed to be outstanding for the purpose of computing the
percentage ownership of any other person.

Plan of distribution

The selling stockholders may sell the shares from time to time. The selling
stockholders will act independently of us in making decisions regarding the
timing, manner and size of each sale. The sales may be made on one or more
exchanges or in the over-the-counter market or otherwise, at prices and at
terms then prevailing or at prices related to the then current market price,
or in negotiated transactions. The selling stockholders may effect such
transactions by selling the shares to or through broker-dealers. The shares
may be sold by one or more of, or a combination of, the following:

  . a block trade in which the broker-dealer will attempt to sell the shares
    as agent but may position and resell a portion of the block as principal
    to facilitate the transaction,

  . purchases by a broker-dealer as principal and resale by such broker-
    dealer for its account under this prospectus,

  . an exchange distribution in accordance with the rules of such exchange,

  . ordinary brokerage transactions and transactions in which the broker
    solicits purchasers, and

  . in privately negotiated transactions.

To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the selling stockholders may arrange for other
broker-dealers to participate in the resales.

The selling stockholders may enter into hedging transactions with broker-
dealers in connection with distributions of the shares or otherwise. In these
transactions, broker-dealers may engage in short sales of the shares in the
course of hedging the positions they assume with selling stockholders. The
selling stockholders also may sell shares short and redeliver the shares to
close out such short positions. The selling stockholders may enter into option
or other transactions with broker-dealers which require the delivery to the
broker-dealer of the shares. The broker-dealer may then resell or otherwise
transfer such shares under this prospectus. The selling stockholders also may
loan or pledge the shares to a broker-dealer. The broker-dealer may sell the
shares so loaned, or upon a default the broker-dealer may sell the pledged
shares under this prospectus.

Broker-dealers or agents may receive compensation in the form of commissions,
discounts or concessions from selling stockholders. Broker-dealers or agents
may also receive compensation from the purchasers of the shares for whom they
act as agents or to whom they sell as principals, or both. Compensation as to
a particular broker-dealer might be in excess of customary commissions and
will be in amounts to be negotiated in connection with the sale. Broker-
dealers or agents and any other participating broker-dealers or the selling
stockholders may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act of 1933, the Securities Act, in connection
with sales of the shares. Accordingly, any such commission, discount or
concession received by them and any profit on the resale of the shares
purchased by them may be deemed to be underwriting discounts or commissions
under the Securities Act. Because selling stockholders may be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act, the
selling stockholders will be subject to the prospectus delivery requirements
of the Securities Act. In addition, any securities covered by this prospectus
which qualify for sale to comply with Rule 144 promulgated under the
Securities Act may be sold under Rule 144 rather than under this prospectus.
The selling stockholders have advised us that they have not entered into any
agreements, understandings or arrangements with any underwriters or broker-
dealers regarding the sale of their securities. There is no underwriter or
coordinating broker acting in connection with the proposed sale of shares by
the selling stockholders.

PLAN OF DISTRIBUTION     ALTERNATE COVER PAGE FOR SHELF PROSPECTUS

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

The shares will be sold only through registered or licensed brokers or dealers
if required under applicable state securities laws. In addition, in certain
states the shares may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the
registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the shares may not simultaneously engage in
market making activities with respect to our common stock for a period of two
business days prior to the commencement of such distribution. In addition,
each selling stockholder will be subject to applicable provisions of the
Exchange Act and the associated rules and regulations under the Exchange Act,
including Regulation M, which provisions may limit the timing of purchases and
sales of shares of our common stock by the selling stockholders. We will make
copies of this prospectus available to the selling stockholders and have
informed them of the need to deliver copies of this prospectus to purchasers
at or prior to the time of any sale of the shares.

We will file a supplement to this prospectus, if required, to comply with Rule
424(b) under the Securities Act upon being notified by a selling stockholder
that any material arrangements have been entered into with a broker-dealer for
the sale of shares through a block trade, special offering, exchange
distribution or secondary distribution or a purchase by a broker or dealer,
such supplement will disclose:

 . the name of each such selling stockholder and of the participating broker-
  dealer(s),

 . the number of shares involved,

 . the price at which such shares were sold,

 . the commissions paid or discounts or concessions allowed to such broker-
  dealer(s), where applicable,

 . that such broker-dealer(s) did not conduct any investigation to verify the
  information set out or incorporated by reference in this prospectus, and

 . other facts material to the transaction.

In addition, upon being notified by a selling stockholder that a donee or
pledgee intends to sell more than 500 shares, we will file a supplement to
this prospectus.

We will bear all costs, expenses and fees in connection with the registration
of the shares. The selling stockholders will bear all commissions and
discounts, if any, attributable to the sales of the shares. The selling
stockholders may agree to indemnify any broker-dealer or agent that
participates in transactions involving sales of the shares against certain
liabilities, including liabilities arising under the Securities Act.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933.

As permitted by the Delaware General Corporation Law, the registrant's Second
Amended and Restated Certificate of Incorporation includes a provision that
eliminates the personal liability of its directors for monetary damages for
breach of fiduciary duty as a director, except for liability (1) for any
breach of the director's duty of loyalty to the registrant or its
stockholders, (2) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (3) under section 174 of
the Delaware General Corporation Law (regarding unlawful dividends and stock
purchases) or (4) for any transaction from which the director derived an
improper personal benefit.

As permitted by the Delaware General Corporation Law, the bylaws of the
registrant provide that (1) the registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to certain very limited exceptions, (2) the
registrant may indemnify its other employees and agents as set forth in the
Delaware General Corporation Law, (3) the registrant is required to advance
expenses, as incurred, to its directors and executive officers in connection
with a legal proceeding to the fullest extent permitted by the Delaware
General Corporation Law, subject to certain very limited exceptions and (4)
the rights conferred in the bylaws are not exclusive.

The registrant has entered into indemnification agreements with each of its
directors and executive officers to give such directors and officers
additional contractual assurances regarding the scope of the

- -------------------------------------------------------------------------------
                                                                           II-1
<PAGE>

PART II

- -------------------------------------------------------------------------------
indemnification set forth in the registrant's Second Amended and Restated
Certificate of Incorporation and to provide additional procedural protections.
At present, there is no pending litigation or proceeding involving a director,
officer or employee of the registrant regarding which indemnification is
sought, nor is the registrant aware of any threatened litigation that may
result in claims for indemnification.

Reference is also made to Section 9 of the Underwriting Agreement, which
provides for the indemnification of officers, directors and controlling
persons of the registrant against certain liabilities. The indemnification
provision in the registrant's Second Amended and Restated Certificate of
Incorporation, bylaws and the indemnification agreements entered into between
the registrant and each of its directors and executive officers may be
sufficiently broad to permit indemnification of the registrant's directors and
executive officers for liabilities arising under the Securities Act of 1933.

The registrant has applied for liability insurance for its officers and
directors.

Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere in this prospectus:

has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the 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 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 Act and will be governed by the
final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

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

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

The Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment 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.

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

    SECTION 8. Additional Agreements of the Corporation.
    ---------  ----------------------------------------

    8.1   Right of First Refusal.
          ----------------------

          (a)  Subject to the limitations set forth in paragraph (i) of this
Section 8.1 and in Section 8.9, the Corporation hereby grants to each Investor,
each Founder, and any of their respective permitted assignees described in
paragraph (j) of this Section 8.1 (each a "Right Holder") the right of first
refusal to purchase, pro rata, all (or any part) of any New Securities (as
defined in this Section 8.1(b)) that the Corporation may, from time to time,
propose to sell or issue.  Each such Right Holder's pro rata share, for purposes
of this right of first refusal, is the ratio of (i) the number of shares of
Common Stock then held of record by, or issuable on conversion of Series B
Preferred or Series A Preferred (together, "Preferred Stock") then held of
record by, such Right Holder to (ii) the sum of the total number of shares of
the Common Stock issued and outstanding plus the total number of shares of
Common Stock issuable upon conversion of the Preferred Stock, in each case at
such time (the "Basic Amount").

          (b)  "New Securities" shall mean any equity securities of the
Corporation, whether now authorized or not, and rights, options, or warrants to
purchase said equity securities, and securities of any type whatsoever that are,
or may become, convertible into said equity securities; provided, however, that
                                                        --------  -------
"New Securities" does not include (i) securities offered to the public pursuant
to a registration statement filed under the Securities Act, the gross proceeds
to the Corporation from the sale of which would equal or exceed $10,000,000;
(ii) securities issued pursuant to the acquisition of another corporation by the
Corporation by merger, purchase of substantially all of the assets, or other
reorganization whereby the Corporation acquires not less than 51% of the voting
power of such corporation; (iii) up to 700,000 shares (appropriately adjusted to
take account of any stock split, stock dividend, combination of shares or the
like) of Common Stock (or related options) issued to employees, officers or
other persons performing services for the Corporation pursuant to any stock
offering, plan or arrangement approved by the Board of Directors of the
Corporation, which number may be adjusted upward by the affirmative vote of two-
thirds of the whole Board of Directors; (iv) securities issued in connection
with any stock split, stock dividend or recapitalization by the Corporation; (v)
shares of Common Stock issued upon conversion of the Shares; (vi) securities
issuable upon exercise or conversion of any rights, options, warrants or
convertible securities outstanding on the date of this Agreement; (vii)
securities issued to any financial institution in connection with a loan
transaction approved by the Board of Directors of the Corporation; (viii)
securities issued to vendors or customers or to other persons in similar
commercial situations with the Corporation, provided such issuance is

                                      -13-
<PAGE>

approved by the Board of Directors of the Corporation; (ix) securities issued in
connection with obtaining lease financing, whether issued to a lessor, guarantor
or other person involved in the financing, provided such issuance is approved by
the Board of Directors of the Corporation; or (x) any right, option or warrant
to acquire any security convertible into securities excluded from the definition
of New Securities pursuant to clauses (i) through (ix) above.

          (c)  The Corporation shall not issue, sell or exchange, agree to
issue, sell or exchange, or reserve or set aside for issuance, sale or exchange
any New Securities unless the Corporation shall deliver to each Right Holder a
written notice of any proposed or intended issuance, sale or exchange of New
Securities (the "Offer"), which Offer shall (i) identify and describe the New
Securities, (ii) describe the price and other terms upon which they are to be
issued, sold or exchanged, and the number or amount of the New Securities to be
issued, sold or exchanged, (iii) identify the persons or entities to which or
with which the New Securities are to be offered, issued, sold or exchanged and
(iv) offer to issue and sell to or exchange with such Right Holder (a) such
Right Holder's Basic Amount, and (b) any additional portion of the New
Securities as such Right Holder shall indicate it will purchase or acquire
should the other Right Holders subscribe for less than their Basic Amounts (the
"Undersubscription Amount"). Each Right Holder shall have the right, for a
period of 30 days following delivery of the Offer, to purchase or acquire, at a
price and upon the other terms specified in the Offer, the number or amount of
New Securities described above. The Offer by its terms shall remain open and
irrevocable for such 30-day period.

          (d)  To accept an Offer, in whole or in part, a Right Holder must
deliver a written notice to the Corporation prior to the end of the 30-day
period of the Offer, setting forth the portion of the Right Holder's Basic
Amount that such Right Holder elects to purchase and, if such Right Holder shall
elect to purchase all of its Basic Amount, the Undersubscription Amount (if any)
that such Right Holder elects to purchase (the "Notice of Acceptance").  If the
Basic Amounts subscribed for by all Right Holders are less than the total New
Securities, then each Right Holder who has set forth an Undersubscription Amount
in its Notice of Acceptance shall be entitled to purchase, in addition to the
Basic Amount subscribed for, the Undersubscription Amount it has subscribed for;
provided, however, that should the Undersubscription Amounts subscribed for
- --------  -------
exceed the difference between the New Securities and the Basic Amounts
subscribed for (the "Available Undersubscription Amount"), each Right Holder who
has subscribed for any Undersubscription Amount shall be entitled to purchase
only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Right Holder bears to the total
Undersubscription Amounts subscribed for by all Right Holders, subject to
rounding by the Board of Directors to the extent it reasonably deems necessary.

          (e)  In the event that Notices of Acceptance are not given by the
Right Holders in respect of all the New Securities, the Corporation shall have
90 days from the expiration of the period set forth in paragraph (c) above to
issue, sell or exchange all or any part of such New Securities as to which a
Notice of Acceptance has not been given by the Right Holders (the "Refused
Securities"), but only to the offerees or purchasers and only upon terms and
conditions (including, without limitation, unit prices and interest rates) which
are described in the Offer.

                                      -14-
<PAGE>

          (f)  In the event the Corporation shall propose to sell less than all
the Refused Securities (any such sale to be in the manner and on  the terms
specified in paragraph (e) above), then each Right Holder may, at its sole
option and in its sole discretion, reduce the number or amount of the New
Securities specified in its Notice of Acceptance to an amount that shall be not
less than the number or amount of the New Securities that the Right Holder
elected to purchase pursuant to paragraph (d) above multiplied by a fraction,
(i) the numerator of which shall be the number or amount of New Securities the
Corporation actually proposes to issue, sell or exchange (including New
Securities to be issued or sold to Right Holders pursuant to paragraph (d) above
prior to such reduction) and (ii) the denominator of which shall be the amount
of all New Securities.  In the event that any Right Holder so elects to reduce
the number or amount of New Securities specified in its Notice of Acceptance,
the Corporation may not issue, sell or exchange more than the reduced number or
amount of the New Securities unless and until such securities have again been
offered to the Right Holders in accordance with paragraph (c) above.

          (g)  Upon the closing of the issuance, sale or exchange of all or less
than all the Refused Securities, the Right Holders shall acquire from the
Corporation, and the Corporation shall issue to the Right Holders, the number or
amount of New Securities specified in the Notices of Acceptance, as reduced
pursuant to paragraph (f) above if the Right Holders have so elected, upon the
terms and conditions specified in the Offer.  The purchase by the Right Holders
of any New Securities is subject in all cases to the preparation, execution and
delivery by the Corporation and the Right Holders of a purchase agreement
relating to such New Securities reasonably satisfactory in form and substance to
the Right Holders and their respective counsel.

          (h)  Any New Securities not acquired by the Right Holders or other
persons in accordance with paragraph (e) above may not be issued, sold or
exchanged until they are again offered to the Right Holders under the procedures
specified in this Agreement.

          (i)  This right of first refusal shall run to each Investor, each
Founder and any of their respective permitted assignees under paragraph (j) of
this Section 8.1 only for so long as they hold the following number of shares of
Common Stock (including in such number shares of Common Stock issuable upon
conversion of Preferred Stock):

               (i)  in the case of the Founders, the Investors who were parties
to the Original Purchase Agreement and their permitted assignees, 50,000 shares;
and

               (ii) in the case of all other Investors and their permitted
assignees, 200,000 shares.

          (j)  This right of first refusal may be assigned, in whole or in part,
(i) to any Affiliate (as hereinafter defined) of any Right Holder or (ii) to any
assignee who acquires not less than 50,000 shares of Common Stock in the case of
an assignment from assignor described in clause (i) of paragraph (i) of this
Section 8.1, or 200,000 shares of Common Stock in the case of an assignment from
an assignor described in clause (ii) of paragraph (i) of this Section 8.1 (in
each case, including in such number shares of Common Stock issuable upon
conversion of Preferred Stock and appropriately adjusted to take account of any
stock split, stock dividend,

                                      -15-

combination of shares, or the like). As used in this Section, an Affiliate of a
Right Holder shall mean any partner of the Right Holder that is a partnership or
any person or entity that, directly or indirectly, through one or more
intermediaries, controls, or is controlled by, or is under common control with,
the Right Holder.

          (k)  This Section 8.1 shall supersede and replace Section 8 of the
Original Purchase Agreement, which Section 8 shall no longer have any force or
effect.

     8.2  Keeping of Records and Books of Account.  The Corporation shall keep,
          ---------------------------------------
and cause each subsidiary to keep, adequate records and books of account, in
which complete entries will be made in accordance with generally accepted

the Corporation may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Corporation
- --------  -------
from discontinuing the lease or maintenance of any such facilities if such
discontinuance is, in the good faith judgment of the Board of Directors of the
Corporation, desirable in the conduct of its business and would not have a
material adverse effect on the Corporation.

underwriter's discounts and commissions), appropriately adjusted to take account

                                   EXHIBIT A
                                   ---------

     Section 1.  Liquidation Rights.
     ---------   ------------------

          (a)  In the event of any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary, the holders of
each share of the Series B Preferred Stock shall be entitled to be paid first
out of the assets of the Corporation available for distribution to holders of
the Corporation's capital stock of all classes an amount equal to the greater
of:

               (i)  $1.50 per share of Series B Preferred Stock (which amount
     shall be subject to equitable adjustment whenever there shall occur a stock
     dividend, stock split, combination of shares, reclassification or other
     similar event with respect to the Series B Preferred Stock) plus all
     dividends declared but unpaid thereon, to and including the date full
     payment shall be tendered to the holders of the Series B Preferred Stock
     with respect to such liquidation, dissolution or winding up, or

               (ii) such amount per share of Series B Preferred Stock as would
     have been payable had all shares of Series B Preferred Stock been converted
     to Common Stock immediately prior to such event of liquidation, dissolution
     or winding up pursuant to the provisions of Section 2 hereof, plus all
     dividends declared but unpaid on each share of Series B Preferred Stock to
     and including the date full payment shall be tendered to the holders of the
     Series B Preferred Stock with respect to such liquidation, dissolution or
     winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series B Preferred Stock of all amounts so
distributable to them, then the entire assets of the Corporation available for
such distribution shall be distributed ratably among the holders of the Series B
Preferred Stock in proportion to the full preferential amount each such holder
is otherwise entitled to receive.

     After such payments shall have been made in full to the holders of the
Series B Preferred Stock or funds necessary for such payments shall have been
not aside by the Corporation in trust
<PAGE>

for the account of holders of Series B Preferred Stock so as to be available for
such payments, the holders of each share of the Series A Preferred Stock 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 an
amount equal to the greater of:

               (i)  $0.50 per share of Series A Preferred Stock (which amount
     shall be subject to equitable adjustment whenever there shall occur a stock
     dividend, stock split, combination of shares, reclassification or other
     similar event with respect to the Series A Preferred Stock) plus all
     dividends declared but unpaid thereon, to and including the date full
     payment shall be tendered to the holders of the Series A Preferred Stock
     with respect to such liquidation, dissolution or winding up, or

               (ii) such amount per share of Series A Preferred Stock as would
     have been payable had all shares of Series A Preferred Stock been converted
     to Common Stock immediately prior to such event of liquidation, dissolution
     or winding up pursuant to the provisions of Section 2 hereof, plus all
     dividends declared but unpaid on each share of Series A Preferred Stock to
     and including the date full payment shall be tendered to the holders of the
     Series A Preferred Stock with respect to such liquidation, dissolution or
     winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series A Preferred Stock of all amounts so
distributable to them, then the entire remaining assets of the Corporation
available for such distribution shall be distributed ratably among the holders
of the Series A Preferred Stock in proportion to the full preferential amount
each such holder is otherwise entitled to receive.

     After such payments shall have been made in full to the holders of the
Series B Preferred Stock and to the holders of the Series A Preferred Stock, or
funds necessary for such payments shall have been set aside by the Corporation
in trust for the account of holders of Preferred Stock so as to be available for
such payments, the remaining assets available for distribution shall be
distributed among the holders of the Common Stock ratably in proportion to the
number of shares of Common Stock held by them.

     Upon conversion of shares of Series B Preferred Stock or Series A Preferred
Stock into shares of Common Stock Pursuant to Section 2 below, the holder of
such Common Stock shall not be entitled to any preferential payment or
distribution in case of any liquidation dissolution or winding up, but shall
share ratably in any distribution of the assets of the Corporation to all the
holders of Common Stock.

     The amounts payable with respect to shares of Series B Preferred Stock and
Series A Preferred Stock under this Section 1(a) are sometimes hereinafter
referred to as "Series B Liquidation Payments" and "Series A Liquidation
Payments," respectively, and together are sometimes hereinafter referred to as
the "Liquidation Payments."

          (b)  Distributions Other than Cash.  Whenever the distributions
               -----------------------------
provided for in this Section 1 shall be payable in property other than cash, the
value of such distributions shall be

                                      -2-
<PAGE>

the fair market value of such property as determined in good faith by the Board
of Directors of the Corporation.

          (c)  Merger as Liquidation, etc.  The merger or consolidation of the
               --------------------------
Corporation into or with another corporation (except one in which the holders of
capital stock of the Corporation immediately prior to such merger or
consolidation continue to hold at least eighty percent (80%) in voting power of
the capital stock of the surviving corporation, in which case the provisions of
Subsection 2(h) shall apply), or the sale of all or substantially all of the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the affairs of the Corporation for purposes of this Section 1 with
respect to the Series B Preferred Stock unless the holders of at least eighty-
five percent (85%) of the then outstanding shares of the Series B Preferred
Stock elect to the contrary, and with respect to the Series A Preferred Stock
unless the holders of at least eighty percent (80%) of the then outstanding
shares of the Series A Preferred Stock elect to the contrary, such election in
either case to be made by giving written notice thereof to the Corporation at

Stock or Series A Preferred Stock, as the case may be.  Unless such election is
made, any amounts received by the holders of the Series B Preferred Stock and
the Series A Preferred Stock as a result of such merger or consolidation shall
be deemed to be applied toward, and all consideration received by the
Corporation in such asset sale together with all other available assets of the
Corporation shall be distributed toward, the Liquidation Payments attributable
to such shares of Series B Preferred Stock and Series A Preferred Stock,
respectively, in the order of preference set forth in Section 1.

          (d)  Notice.  Written notice of any proposed liquidation, dissolution
               ------

1(c)), stating a payment date, the amount of the Liquidation Payments and the
place where said Liquidation Payments shall be payable, shall be given by first

     Section 2.  Conversion.  The holders of Preferred stock shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert; Conversion Price.  Each share of Preferred
               ----------------------------------
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 Preferred Stock, into such number of fully paid and
nonassessable shares of Common Stock as is determined in accordance with the
following:

               (i)  in the case of the Series B Preferred Stock, by dividing
     $1.50 by the Series B Conversion Price, determined as hereinafter provided,
     in effect at the time of

                                      -3-
<PAGE>

     conversion. The Conversion Price at which shares of Common Stock shall be
     deliverable upon conversion of Series B Preferred Stock without the payment
     of any additional consideration by the holder thereof (the "Series B
     Conversion Price") shall initially be $1.50 per share of Common Stock. Such
     initial Series B Conversion Price shall be subject to adjustment, in order
     to adjust the number of shares of Common Stock into which the Series B
     Preferred Stock is convertible, as hereinafter provided.

               (ii) in the case of the Series A Preferred Stock, by dividing
     $0.50 by the Series A Conversion Price, determined as hereinafter provided,
     in effect at the time of conversion.  The Conversion Price at which shares
     of Common Stock shall be deliverable upon conversion of Series A Preferred
     Stock without the payment of any additional consideration by the holder
     thereof (the "Series A Conversion Price") shall initially be $0.50 per
     share of Common Stock.  Such initial Series A Conversion Price shall be
     subject to adjustment, in order to adjust the number of shares of Common
     Stock into which the Series A Preferred Stock in convertible, an
     hereinafter provided.

          (b)  Automatic Conversion.  Each share of Series B Preferred Stock
               --------------------
shall automatically be converted into shares of Common Stock at the applicable
Series B conversion Price than in effect upon:

               (i)  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 at an offering price
     per share (prior to underwriter commissions and discounts) of not less than
     $4.50 (as adjusted pursuant to Subsection 2(e)(vi) hereof to reflect any
     stock dividends, distributions, combinations, reclassifications or other
     like transactions affected by the Corporation in respect of its Common
     Stock) and with gross proceeds to the Corporation of not less than
     $10,000,000 (in the event of which offering, the person(s) entitled to
     receive the Common Stock issuable upon such conversion of the Series B
     Preferred Stock shall not be deemed to have converted that Series B
     Preferred Stock until the closing of such offering); or

               (ii) the written election of the holders of not less than eighty-
     five percent (85%) of the then outstanding shares of the Series B Preferred
     Stock to require such mandatory conversion.

     Each share of Series A Preferred Stock shall automatically be converted
into shares of Common Stock at the applicable Series A Conversion Price then in
effect upon:

               (i)  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 at an offering price
     per share (prior to underwriter commissions and discounts) of not less than
     $2.50 (as adjusted pursuant to Subsection 2(e)(vi) hereof to reflect any
     stock dividends, distributions, combinations, reclassifications or other
     like transactions affected by the Corporation in respect of its Common
     Stock) and with gross

                                      -4-
<PAGE>

     proceeds to the Corporation of not less than $10,000,000 (in the event of
     which offering, the person(s) entitled to receive the Common Stock issuable
     upon such conversion of the Series A Preferred Stock shall not be deemed to
     have converted that Series A Preferred Stock until the closing of such
     offering); or

               (ii) the written election of the holders of not less than eighty
     percent (80%) of the then outstanding shares of the Series A Preferred
     Stock to require such mandatory conversion.

          (c)  Mechanics of Automatic Conversions.  Upon the occurrence of an
               ----------------------------------
event specified in Subsection 2(b), the Series B Preferred Stock or the Series A
Preferred Stock, as applicable, or both, shall be converted automatically
without any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered to the Corporation or its
transfer agent; provided, however, that all holders of shares of Preferred Stock
being converted shall be given written notice of the occurrence of an event
specified in Subsection 2(b) including the date such event occurred (the
"Mandatory Conversion Date"), and the Corporation shall not be obligated to
issue certificates evidencing the shares of Common Stock issuable upon such
conversion unless certificates evidencing such shares of the Preferred Stock
being converted are either delivered to the Corporation or its transfer agent,
or the holder notifies the Corporation or any transfer agent that such
certificates have been lost, stolen, or destroyed and executes 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 bond.  On the Mandatory Conversion Date, all
rights with respect to the Preferred Stock so converted shall terminate, except
any of the rights of the holder thereof, upon surrender of the holder's
certificate or certificates therefor, to receive certificates for the number of
shares of Common Stock into which such Preferred Stock has been converted,
together with cash in an amount equal to all dividends declared but unpaid on,
and any and all other amounts owing with respect to, the shares of Preferred
Stock converted to and including the time of conversion.  Upon the automatic
conversion of the Preferred Stock, the holders of such Preferred Stock shall
surrender the certificates representing such shares at the office of the
Corporation or of its transfer agent.  If so required by the Corporation,
certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the
Corporation, duly executed by the registered holder or by the holder's attorney
duly authorized in writing.  Upon surrender of such certificates there shall be
issued and delivered to such holder, promptly at such office and in the 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
the Preferred Stock surrendered were convertible on the date on which such
automatic conversion occurred, together with cash in an amount equal to all
dividends declared but unpaid on, and any and all other amounts owing with
respect to, the shares of Preferred Stock converted to and including the time of
conversion.  No fractional share of Common Stock shall be issued upon the
mandatory conversion of the Preferred Stock.  In lieu of any fractional share to
which the holder would otherwise be entitled, the Corporation shall pay cash
equal to such fraction multiplied by the applicable Conversion Price then in
effect.

                                      -5-
<PAGE>

          (d)  Mechanics of Optional Conversions.  Before any holder of
               ---------------------------------
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, the holder shall surrender the certificate or certificates therefor at
the office of the Corporation or of any transfer agent for the Preferred Stock,
and shall give written notice to the corporation at such office that the holder
elects to convert the same and shall state therein the holder's name or the name
or names of the holder's nominees in which the holder wishes the certificate or
certificates for shares of Common Stock to be issued. On the date of conversion,
all rights with respect to the Preferred Stock so converted shall terminate,
except any of the rights of the holder thereof, upon surrender of the holder's
certificate or certificates therefor, to receive certificates for the number of
shares of Common Stock into which such Preferred Stock has been converted and
cash in an amount equal to all dividends declared but unpaid thereon and any and
all other amounts owing with respect thereto at such time. If so required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or by
the holder's attorney duly authorized in writing. No fractional share of Common
Stock shall be issued upon the optional conversion of Preferred Stock. In lieu
of any fractional share to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the applicable
Conversion Price then in effect. The Corporation shall, as soon as practicable
after surrender of the certificate or certificates for conversion, issue and
deliver at such office to such holder of Preferred Stock, or to the holder's
nominee or nominees, a certificate or certificates for the number of shares of
Common Stock to which the holder shall be entitled as aforesaid, together with
cash in lieu of any fraction of a share and cash in an amount equal to all
dividends declared but unpaid thereon and any and all other amounts owing with
respect thereto at such time. 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 Preferred 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.

          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 in any such case in
          which Additional Shares of Common Stock are deemed to be issued;

                         (A)   no further adjustment in the Series B Conversion
               Price or the Series A 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;

                         (B)   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 Series B
               Conversion Price and the Series A 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;

                         (C)   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 Series B
               Conversion Price and the Series A 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:

                              (I)  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

                                      -8-
<PAGE>

                    received by the Corporation upon such conversion or
                    exchange; and

                              (II)     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 Subsection 2(a)(v)) upon the issue of the
                    Convertible Securities with respect to which such Options
                    were actually exercised;

                         (D)  no readjustment pursuant to clause (B) or (C)
               above shall have the effect of increasing the Series B Conversion
               Price or the Series A Conversion Price to an amount which exceeds
               the lower of (i) the respective Conversion Price on the original
               adjustment date, or (ii) the respective Conversion Price that
               would have resulted from any issuance of Additional Shares of
               Common Stock between the original adjustment date and such
               readjustment date;

                         (E)  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 Series B Conversion Price or the Series A
               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 (C) above; and

                         (F)  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 Series B
               Conversion Price and the Series A Conversion Price which became
               effective on such record date shall be cancelled as of the close
               of business on such record date, and thereafter the respective
               Conversion Prices shall be adjusted pursuant to this Subsection
               2(e)(iii) as of the actual date of their issuance.

                    (2)  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 events Additional Shares of Common Stock
          shall be deemed to have been issued:

                                      -9-
<PAGE>

                         (A)  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

                         (B)  in the case of any such subdivision, at the close
               of business on the date immediately prior to the date upon which
               such 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 in the Series B Conversion Price
               and the Series A Conversion Price which became effective on such
               record date shall be cancelled as of the close of business on
               such record date, and thereafter the respective Conversion Prices
               shall be adjusted pursuant to this Section 2(e)(iii) as of the
               time of actual payment of such dividend.

               (iv)   Adjustment of Conversion Price Upon Issuance of Additional
                      ----------------------------------------------------------
     Shares of Common Stock.  In the event that at any time or from time to time
     ----------------------
     after the Original Issue Date, the Corporation shall issue Additional
     Shares of Common Stock (including, without limitation, Additional Shares of
     Common Stock deemed to be issued pursuant to Subsection 2(e)(iii)(1) but
     excluding Additional Shares of Common Stock deemed to be issued pursuant to
     Subsection 2(e)(iii)(2), which event is dealt with in Subsection
     2(e)(vi)(1)), without consideration or for a consideration per share less
     than the applicable Series B Conversion Price or Series A Conversion Price
     in effect on the date of and immediately prior to such issue, then and in
     such event, such Series B Conversion Price or Series A Conversion Price, as
     the case may be, shall be reduced, concurrently with such issue, to a price
     (calculated to the nearest cent) determined in accordance with the
     following formula:

                                     (P//1//) (Q//1//) + (P//2//) (Q//2//)

                                                Q//1// + Q//2//

     where:

               NCP      =    New Series B Conversion Price or Series A
                             Conversion Price, as applicable.

               P//1//   =    Series B Conversion Price or Series A Conversion
                             Price, an applicable, in effect immediately prior
                             to new issue.

               Q//1//   =    Number of shares of Common Stock outstanding, or
                             deemed to be outstanding as set forth below,
                             immediately prior to such issue.

<PAGE>

               P//2//   =    Weighted average price per share received by the
                             Corporation upon such issue.

               Q//2//  =    Number of shares of Common Stock issued, or
                             deemed to have been issued, in the subject
                             transaction.

     provided that for the purpose of this Subsection 2(e)(iv), all shares of
     --------
     Common Stock issuable upon exercise or conversion of any Options or
     Convertible Securities outstanding immediately prior to such issue shall be
     deemed to be outstanding, and immediately after any Additional Shares of
     Common Stock are deemed issued pursuant to Subsection 2(e)(iii), such
     Additional Shares of Common Stock shall be deemed to be outstanding; and
     provided further, that the applicable Conversion Price shall not be so
     ----------------
     reduced at any time if the amount of such reduction would be an amount less
     than $.01, 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 $.01 or more.

               (v)   Determination of Consideration.  For purposes of this
                     ------------------------------
     Subsection 2(e), the consideration received by the Corporation for the
     issue of any Additional Shares of Common Stock shall be computed as
     follows:

                    (1)  Cash and Property:  Such consideration shall:
                         -----------------

                         (A) 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;

                         (B) insofar as it consists of property other than cash,
               be computed at the fair value thereof at the time of such issue,
               an determined in good faith by the Board of Directors; and

                         (C) in the event 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 (A) and (B) above, as determined in good
               faith by the Board of Directors.

                    (2)  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 Subsection 2(e)(iii)(1),
          relating to Options and Convertible Securities, shall be determined by
          dividing (x) 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

                                     -11-
<PAGE>

          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 (y) 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.
     ----------------------------------------------

                    (1) Stock Dividends, Distributions or Subdivisions.  In the
                        ----------------------------------------------
          event the Corporation shall be deemed to issue Additional Shares of
          Common Stock pursuant to Subsection 2(e)(iii)(2) in a stock dividend,
          stock distribution or subdivision, the Series B Conversion Price and
          the Series A Conversion Price in effect immediately before such deemed
          issuance shall, concurrently with the effectiveness of such deemed
          issuance, be proportionately decreased.

                    (2) 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 Series B Conversion Price and the Series A
          Conversion Price in effect immediately prior to such combination or
          consolidation shall, concurrently with the effectiveness of such
          combination or consolidation, be proportionately increased.

          (f) Adjustments for Certain Dividends and Distributions.  In the event
              ---------------------------------------------------
that at any time or from time to time after the Original Issue Date the
Corporation shall make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive, a dividend or other distribution
payable in securities of the Corporation other than shares of Common Stock, then
and in each such event provision shall be made so that the holders of Preferred
Stock shall receive upon conversion thereof in addition to the number of shares
of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had their Preferred Stock been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period, giving application during such period to all adjustments called for
herein.

          (g) Adjustment for Reclassification, Exchange, or Substitution.  In
              ----------------------------------------------------------
the event that at any time or from time to time after the Original Issue Date,
the Common Stock issuable upon the conversion of Preferred Stock shall be
changed into the same or a different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
above, or a merger, consolidation, or sale of assets provided for below), then
and in each such event the holder of any share or shares of Preferred Stock
shall have the right thereafter to

                                     -12-
<PAGE>

convert such shares into the kind and amount of shares of stock and other
securities and property receivable upon such reorganization, reclassification,
or other change, by the holder of a number of shares of Common Stock equal to
the number of shares of Common Stock into which such shares of Preferred Stock
might have been converted immediately prior to such reorganization,
reclassification, or change, all subject to further adjustment as provided
herein.

          (h)  Adjustment for Merger, Consolidation or Sale of Assets.  In the
               ------------------------------------------------------
event that at any time or from time to time after the Original Issue Date, the
Corporation shall merge or consolidate with or into another entity or sell all
or substantially all of its assets, each share of Preferred Stock as to which
such consolidation, merger or sale is not treated as a liquidation under
Subsection 1(c) shall thereafter be convertible into the kind and amount of
shares of stock or other securities or property to which a holder of the number
of shares of Common Stock of the Corporation deliverable upon conversion of such
Preferred Stock would have been entitled to receive upon such consolidation,
merger or sale; and, in such case, appropriate adjustment (as determined in good
faith by the Board of Directors) shall be made in the application of the
provisions set forth in this Section 2 with respect to the rights and interest
thereafter of the holders of Preferred Stock, to the end that the provisions set
forth in this Section 2 (including provisions with respect to changes in and
other adjustments of the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of Preferred Stock.

          (i)  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 2 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
Preferred Stock against impairment.

          (j)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Series B Conversion Price or the Series A
Conversion Price pursuant to this Section 2, 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 Preferred Stock 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 Preferred
Stock, furnish or cause to be furnished 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 the
conversion of each share of Preferred Stock.

          (k)  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

                                     -13-
<PAGE>

holder of Preferred Stock 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.

            (1)  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 conversion of
the Preferred Stock.

            (m)  Certain Taxes.  The Corporation shall pay any issue or transfer
                 -------------
taxes payable in connection with the conversion of Preferred 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
the Preferred Stock.

            (n)  Closing of Books.  The Corporation shall at no time close its
                 ----------------
transfer books against the transfer of any Preferred Stock or of any shares of
Common Stock issued or issuable upon the conversion of any shares of Preferred
Stock in any matter which interferes with the timely conversion or transfer of
such Preferred Stock or Common Stock.

then convertible), voting collectively as a single class, the Corporation will
not:

                    (i)       consent to any liquidation, dissolution or winding

     Section 4.  Voting Rights.  Except as otherwise required by law or
     ----------  -------------
hereinafter set forth, the holders of Preferred Stock shall be entitled to
notice of any meeting of stockholders and shall vote together with the holders
of Common Stock an a single class upon any matter submitted to the stockholders
for a vote, on the following basis:

                 (a) Holders of Common Stock shall have one vote per share; and

                 (b) Holders of Preferred Stock shall have that number of votes
     per share as is equal to the number of shares of Common Stock (including
     fractions of a share) into which each such share of Preferred Stock held by
     such holder could be converted on the date for determination of
     stockholders entitled to vote at the meeting or on the date of any written
     consent.

     With respect to all questions as to which, under law, stockholders are
required to vote by classes, each of the Series A Preferred Stock and Series B
Preferred Stock shall vote separately as a single class apart from each other
and from the Common Stock.

     Section 5.  Dividends.
     ---------   ---------

            (a)  The holders of Series B Preferred Stock shall be entitled to
receive, from funds legally available therefor, a noncumulative dividend at the
rate of $.05 per share per annum, payable when and as declared by the Board of
Directors.  No dividends shall be declared or paid to the holders of Series A
Preferred Stock or Common Stock unless the holders of Series B Preferred Stock
have been paid in full all of the dividends to which they are entitled, nor
shall any dividends be declared or paid to the holders of Series A Preferred
Stock or Common Stock at a rate greater than the rate paid to the holders of
Series B Preferred Stock.

            (b)  Subject to Subsection 5(a), dividends may be declared and paid
on Series A Preferred Stock from funds lawfully available therefor as and when
determined by the Board of Directors of the Corporation. If, when and as
dividends are declared and paid on shares of Series A Preferred Stock, the
Corporation shall, after making payment in full to the holders of Series B
Preferred Stock the amounts to which they are entitled pursuant to Subsection
5(a), declare and pay at the same time to each holder of Series B Preferred
Stock, a dividend at the same rate, based on the number of shares of Common
Stock into which the Series B Preferred Stock and the Series A Preferred Stock
are convertible on the record date for the determination of holders of Series A
Preferred Stock entitled to receive such dividend.

            (c)  Subject to Subsection 5(a), dividends may be declared and paid
on Common Stock from funds lawfully available therefor as and when determined by
the Board of Directors of the Corporation. If, when and as dividends are
declared and paid on shares of Common Stock, the Corporation shall, after making
payment in full to the holders of Series B Preferred Stock the amounts to which
they are entitled pursuant to Subsection 5(a), declare and pay at the same time
to each holder of Preferred stock, a dividend equal to the dividend which

                                     -16-
<PAGE>

would have been payable to such holder if the shares of Preferred Stock hold by
such holder had been converted into Common Stock on the record date for the
determination of holders of Common Stock entitled to receive such dividend.

     Section 6.  Redemption.
     ---------   ----------

            (a)  In the event that the Corporation shall exercise its put option
to sell shares of capital stock of Sequenom Instruments GmbH to Technologie-
Beteiligungs-Gesellschaft mbH der Deutschen Ausgleichsbank ("TBG") pursuant to
that certain Kooperationsvertrag between the Corporation and TBG relating to the
investment by the Corporation of DM 3 million in Sequenom Instruments GmbH, the
Corporation shall, within 30 days after receipt of the proceeds of the sale of
such shares to the TBG, send notice of such exercise (the "Put Exercise Notice")
by first class mail, postage prepaid, to each holder of record of the Series B
Preferred Stock at its address as it appears on the books of the Corporation,
specifying (i) the amount of proceeds so received from the TBG net of any
expenses incurred in connection therewith (the "Put Net Proceeds"), (ii) the
date (the "Redemption Date") on which the Corporation will redeem shares of
Series B Preferred Stock from electing holders of the Series B Preferred Stock
in accordance with this Section 6, which Redemption Date shall be not less than
45 days nor more than 90 days after the date of such notice (the "Notice Date")
and (iii) each such holder's Pro Rata Redemption Amount (as hereinafter
defined).

            (b)  Each holder of Series B Preferred Stock may elect to have the
Corporation redeem from it on the Redemption Date, to the extent the Corporation
has funds legally available for such purpose, up to a number of shares of Series
B Preferred Stock equal to such holder's Pro Rata Redemption Amount (as
hereinafter defined) at a redemption price of $1.50 per share.  Such election
may be made only by delivering to the Corporation within thirty (30) days after
the Notice Date (i) a written election signed by such holder specifying the
number of shares of Series B Preferred Stock so to be redeemed (which number
shall be not more than such holder's Pro Rata Redemption Amount), and (ii)
certificates for the shares of Series B Preferred Stock so to be redeemed,
together with stock powers therefor duly executed by such holder in blank.

            (c)  For purposes of this Section 6, each holder of Series B
Preferred Stock's "Pro Rata Redemption Amount" shall be the greatest whole
number represented by a fraction, the numerator or which is the product of the
number of shares of Series B Preferred Stock held by such holder times the Put
Net Proceeds, and the denominator or which is the product of the total number of
shares of Series B Preferred Stock issued and outstanding times $1.50.

            (d)  On the Redemption Date the Corporation shall redeem from the
electing holders of Series B Preferred Stock the shares of Series B Preferred
Stock as to which election notices have been properly given, to the extent the
Corporation has funds legally available for such purpose.

            (e)  If the funds of the Corporation legally available for
redemption of shares of Series B Preferred Stock on the Redemption Date are
insufficient to redeem the total number of shares of Series B Preferred Stock
submitted for redemption, those funds which are legally available will be used
to redeem the maximum possible number of whole shares ratably among

                                     -17-
<PAGE>

the holders of such shares in accordance with the manner of determining the "Pro
Rata Redemption Amount" set forth above. The shares of Series B Preferred Stock
not redeemed shall remain outstanding and entitled to all rights and preferences
provided herein.

     Section 7. Residual Rights. All rights accruing to the outstanding shares
     ---------  ---------------

                           ASSIGNMENT OF INVENTIONS
                           ------------------------


          This Assignment of Inventions (the "Assignment") is made as of May 26,
1994, by and between SEQUENOM, INC., a Delaware corporation (the "Company"), and
Dr. Hubert Koster (the "Assignor") having a place of business at 1640 Monument
Street, Concord, MA 01742.

                               R E C I T A L S:
                               ---------------

          A.   Prior to the date hereof, Assignor has been developing certain
technology and products to determine DNA sequencing by mass spectrometry (the
"Products");

          B.   Assignor desires to transfer to the Company all intellectual
property related to the Products, and to cancel certain expenses incurred in
connection with the development thereof, in exchange for the issuance of Common
Stock of the Company; and

          C.   Assignor and the Company intend the foregoing transaction to
qualify as a non-taxable transfer within the meaning of Section 351 of the
Internal Revenue Code of 1986, as amended, in that such transfer will be made
solely in exchange for Common Stock of the Company and immediately thereafter
Assignor will be in control of the Company.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
promises contained herein, the parties agree as follows:

          1.   The recitals set forth above shall be deemed to be a part of this
Agreement as though such provisions had been forth in full in this Agreement.

          2.   In consideration of the issuance of 1,100,000 shares of the
Common Stock of the Company, Assignor hereby assigns to the Company all of his
right, title and interest in and to (i) all inventions and improvements,
designs, know-how, and ideas (including all patents, trademarks, trade names,
copyrights, inventions, trade secrets, proprietary processes and

<PAGE>

formulae, applications for patents, trademarks and copyrights, and other
industrial and intellectual property rights) relating to the Products, including
but not limited to the United States Patent and Trademark Applications and
inventions described on Exhibit A hereto, and (ii) all machines, instruments,
devices, equipment or models incident or related thereto, made, conceived, or
created by Assignor prior to the date of this Assignment, all of which are
hereafter referred to as the "Inventions." This Assignment is intended to
include any additional rights in or to the Inventions received by Assignor after
the effective date of this Assignment, without further consideration to
Assignor, including rights to any credits and royalties arising out of the
Inventions. Assignor further waives and relinquishes his tight to request any
reimbursement by the Company of expenses incurred by or on behalf of Assignor
prior to the date hereof in connection with the development of the Products or
the Inventions.

          3.   Assignor represents and warrants that he has made no prior
license, transfer, assignment or hypothecation of any interest in the Inventions
and that no other person or firm has any interest in the Patent and Patent
Applications and the trademark Application listed in Exhibit A hereto and to the
best of Assignor's knowledge in any other Inventions.  Assignor owns, possesses,
and has the right to use, to bring actions for the infringement of and to
transfer and assign to the Company the Patent and Patent Applications and the
Trademark Application listed in Exhibit A hereto and to the best of Assignor's
knowledge all other Inventions.  No royalties or other amounts will be payable
by the Company to Assignor by reason of its ownership, use or licensing of the
Inventions.  To the best of Assignor's knowledge, no Invention violates any
license or infringes any patent, copyright, trademark, trade secret or other
intellectual property right of any person or entity, nor will royalties or other
amounts be payable by the Company to any person or entity by reason of the
Company's ownership, use or licensing

                                      2.

of the Inventions, nor is there any reasonable basis to believe that any such
violation, infringement or conflict may exist, except that Assignor is aware of,
and hereby gives the Company notice of, U.S. Patent No. 5,288,644 issued on
February 22, 1994 to Rockefeller University (Inventors R.C. Beavis and B.T.
Chait) and now in the possession of Perceptive Biosystems, Cambridge,
Massachusetts. Assignor has not received any notice that any of such Inventions
or the-ownership, use or licensing thereof in the operation or proposed
operation of the Company's business conflicts with the rights of others.
Assignor owns all right, title and interest in and to the Patent and Trademark
Applications described on Exhibit A hereto.

          4.   In support of said Assignment, Assignor further agrees as
follows:

               (a)  To deliver to the company copies of all writings and other
tangible evidence or representations of the Inventions, and any improvements
covered by this Assignment;

               (b)  To execute such additional documents as may reasonably be
required to transfer to the Company Assignor's entire right, title and interest
in or to the Inventions, improvements thereof covered by this Assignment and to
all rights of priority thereto pursuant to the International Convention for
Protection of Industrial Property; and in and to any and all Letters Patent on
said Inventions and/or said improvements that may be granted in the United
States or any foreign country, including each and every Letter Patent granted on
any application which is a division, substitution, or continuation of said
application specifically identified herein, and in and to each and every reissue
or extension of said Letters Patent;

               (c)  Not to make any use of the Inventions or improvements
covered by this Assignment for his benefit or interest and to hold them in
confidence and not to disclose

                                      3.

them to anyone other than personnel of the Company, without the prior written
consent of an officer of the Company;

               (d)  To cooperate with the company whereby said company may enjoy
to the fullest extent the right, title and interest herein conveyed. Such
cooperation shall include: (i) prompt execution of all papers (prepared at the
expense of the Company) which are deemed necessary or desirable by the Company
to perfect in it the right, title and interest herein conveyed; (ii) prompt
execution of all petitions, oaths, specifications, declarations or other papers
(prepared at the expense of the Company) which are deemed necessary or desirable
by the Company for prosecuting said applications specifically identified herein,
for filing and prosecuting substitutions, divisions, continuing or additional

"PART THREE - OTHER STATES INSURANCE" is amended to read:

A. How This Insurance Applies:

   1. We will pay promptly, when due, the benefits required of you by the
      workers' compensation law of any state other than Massachusetts, but only
      if the claim for such benefits involves work performed by a Massachusetts
      employee.

   2. If we are not permitted to pay the benefits directly to persons entitled
      to them under circumstances described in item 1 above, we will reimburse
      you for the benefits required to be paid.


                               IMPORTANT NOTICE


If you hire any employees outside Massachusetts or begin operations in any state
other than Massachusetts, you must obtain insurance coverage in that state and
so whatever else may be required under that state's law, as this endorsement
does not satisfy the requirements of that state's workers' compensation law.

                      -----------------------------------
<PAGE>

                          STOCK RESTRICTION AGREEMENT

     This Agreement made as of December 22, 1995 by and among Sequenom, Inc., a
Delaware corporation (the "Corporation"); Hubert Koster ("Koster"), Nola E.
Masterson ("Masterson") and Robert E. Patterson ("Patterson," and together with
Koster and Masterson, the "Founders"); and the purchasers of shares of the
Corporation's Series B Convertible Preferred Stock, par value $.001 per share
("Series B Preferred Stock"), pursuant to the Series B Convertible Preferred
Stock Purchase Agreement dated as of the date hereof (the "Purchase Agreement"),
including any Additional Investors as defined in the Purchase Agreement (such
purchasers being hereinafter referred to as the "Investors").

                          W I T N E S S E T H  T H A T

     WHEREAS, the Investors wish to purchase from the Corporation certain shares
of Series B Preferred Stock;

     WHEREAS, the Investors' purchase of the Series B Preferred Stock would
materially benefit the Founders as holders of certain shares of the
Corporation's capital stock and rights to acquire such capital stock;

     WHEREAS, it is a condition to the obligations of the Investors under the
Purchase Agreement that this Agreement be executed by the Founders, and the
Founders are willing to execute this Agreement and to be bound by the provisions
hereof;

     NOW, THEREFORE, in consideration of the foregoing, the agreements set forth
below, and the parties', desire to provide for continuity of ownership of the
Corporation to further the interests of the Corporation and its present and
future stockholders, the parties hereby agree with each other as follows:

     1.  Certain Defined Terms.  As used in this Agreement, the following terms
         ---------------------
shall have the following respective meanings:

         (a) "Stock" shall mean and include all shares of the Corporation's
Common Stock, par value $.001 per share ("Common Stock"), any evidences of
indebtedness, shares of capital stock or other securities directly or indirectly
convertible into or exchangeable for Common Stock ("Convertible Securities"),
including without limitation the Series A Convertible Preferred Stock, par value
$.001 per share, of the Corporation, and any rights, options or warrants to
subscribe for, purchase or otherwise acquire Common Stock or Convertible
Securities ("Options"), and all other securities of the Corporation which may be
issued in exchange for or in respect of shares of Common Stock, Convertible
Securities or Options (whether by way of stock split, stock dividend,
combination of shares, reclassification, recapitalization, reorganization, or
any other means).

         (b) "Shares" shall mean and include all shares of Stock now owned or
hereafter acquired by any Founder or any investor.
<PAGE>

     2.   Prohibited Transfers.  None of the Founders shall sell or otherwise
          --------------------
transfer, by gift or otherwise, all or any part of his Shares except in
compliance with the terms of this Agreement.

     3.   Offer of Sale; Notice of Proposed Sale or Transfer.  If any Founder
          --------------------------------------------------
desires to sell or otherwise transfer any of his Shares, or of any interest
therein, whether voluntarily or by operation of law, in any transaction other
than pursuant to clauses (iii) or (iv) of Section 7(a) of this Agreement, such
Founder (the "Selling Founder") shall first deliver written notice of his desire
to do so (the "Notice") to the Corporation and each of the Investors.  The
Notice must specify:  (i) the name and address of the party to which the Selling
Founder proposes to sell or otherwise transfer the Shares or an interest in the
Shares (the "Proposed Transferee"), (ii) the number of Shares the Selling
Founder proposes to sell or otherwise transfer (the "Offered Shares"), (iii) the
consideration per Share to be delivered to the Selling Founder for the proposed
sale or transfer, and (iv) all other material terms and conditions of the
proposed transaction, which must be bona fide.

     4.   Corporation's Option to Purchase.
          --------------------------------

          (a) Except as set forth in Section 7(a), the Corporation shall have
the first option to purchase all or any part of the Offered Shares for the
consideration per Share and on the terms and conditions specified in the Notice.
The Corporation must exercise such option, no later than fifteen (15) business
days after such Notice is deemed to have been delivered to it, by written notice
to the Selling Founder.

          (b) In the event the Corporation does not exercise its option within
such fifteen-business-day period with respect to all of the offered Shares, the
Chief Financial officer of the corporation shall, by the last day of such
period, give written notice of that fact to the Investors (the "Investor
Notice").  The Investor Notice shall specify the number of Offered Shares the
Corporation has elected not to purchase (the "Remaining Shares").

          (c) In the event the Corporation duly exercises its option to purchase
all or a portion of the Offered Shares, the closing of such purchase shall take
place at the offices of the Corporation on the later of (i) the date five
business days after the expiration of such fifteen-business-day period or (ii)
the date that the Investors consummate their purchase of Offered shares under
Section 5(c) hereof.

          (d) To the extent that the consideration proposed to be paid by the
Proposed Transferee for the Offered Shares consists of property other than cash
or a promissory note, the consideration required to be paid by the Corporation
and/or the Investors exercising their options under Sections 4 and 5 hereof,
respectively, may consist of cash equal to the value of such property, as
determined in good faith by agreement of the selling Founder and the Corporation
and/or the Investors acquiring such Offered Shares.

     5.   Investors' Option to Purchase and Right to Participate in Sales.
          ---------------------------------------------------------------

          (a) Except as set forth in Section 7(a), each Investor shall have an
option, exercisable for a period of fifteen (15) business days from the date of
delivery of the Investor Notice, to purchase, on a pro rata basis, its
Proportionate Percentage (as defined below) of the Remaining Shares, for the
consideration per Share and on the terms and conditions set forth in the Notice.
Such option shall be exercised by delivery of written notice to the Chief
Financial Officer of the Corporation.  Alternatively, each Investor may, within
the same fifteen-business-day period, notify the Chief Financial Officer of the
Corporation of its desire to participate in the sale of Shares and to sell, on
the terms as set forth in the Notice including at the same price per share on a
common equivalent basis, up to an equivalent proportion of the Stock owned by
such Investor as the proposed sale of the Remaining Shares represents with
respect to the Shares then owned by the Selling Founder.

          (b) In the event options to purchase have been exercised by the
Investors with respect to some but not all of the Remaining Shares, the Chief
Financial Officer of the Corporation shall promptly give written notice of that
fact to those Investors who have exercised their options within such period (the
"Second Investor Notice").  The Second Investor Notice shall specify the number
of Remaining Shares the Investors have not elected to purchase.  The Investors
who have exercised their options within the fifteen-business-day period
specified in Section 5(a) shall have an additional option, for a period of ten
(10) business days after delivery of the Second Investor Notice, to purchase all
or any part of the balance of such Remaining Shares on the terms and conditions
set forth in the Notice, which option shall be exercised by the delivery of
written notice to the Chief Financial Officer of the Corporation.  In the event
that there are two or more such Investors that choose to exercise the last-
mentioned option for a total number of Remaining Shares in excess of the number
available, the Remaining Shares available for each such Investor's option shall
be allocated to such Investors pro rata based on the amount of Stock owned by
the Investors so electing on a common equivalent basis.

          (c) Promptly after the expiration of the last period for exercise of
an Investor's purchase option, the Chief Financial Officer of the Corporation
shall give written notice to the Selling Founder and the purchasing Investors,
specifying the number of Remaining Shares to be purchased by each purchasing
Investor.  The closing of the purchase of the Remaining Shares shall take place
at the offices of the Corporation no later than five (5) business days after
delivery of such notice to the Selling Founder and the purchasing Investors.

          (d) As used in this Section 5, the term "Proportionate Percentage"
shall mean with respect to each Investor a fraction, the numerator of which
shall be the amount of Stock owned by such Investor, and the denominator of
which shall be the total amount of Stock owned by all Investors, in each case on
a common equivalent basis.

     6.   Co-Sale.
          -------

          (a) If the Corporation and the Investors do not exercise their options
to purchase all of the Offered Shares within the periods described in this
Agreement (the "Option Period"), then each Investor which has, pursuant to
Section 5(a), expressed a desire to sell shares

                                      -3-
<PAGE>

in the transaction (a "Participating Investor") shall be entitled to do so
pursuant to this Section. The Chief Financial Officer of the Corporation shall
promptly, on expiration of the Option Period, notify the Selling Founder of the
aggregate amount of Stock the Participating Investors wish to sell. The Selling
Founder shall use his best efforts to interest the Proposed Transferee in
purchasing, in addition to the Remaining Shares not subscribed for by the
Investors, the Stock the Participating Investors wish to sell. If the Proposed
Transferee does not wish to purchase all of the Stock made available by the
Selling Founder and the Participating Investors, then each Participating
Investor and the Selling Founder shall be entitled to sell, on the terms and
conditions set forth in the Notice and on the same price per share on a common
equivalent basis, a portion of the Stock being sold to the Proposed Transferee,
in the same proportion as such Selling Founder or Participating Investor's
ownership of Stock on a common equivalent basis bears to the aggregate amount of
Stock owned by the Selling Founder and the Participating Investors on a common
equivalent basis. The transaction contemplated by the Notice shall be
consummated not later than 60 days after the expiration of the Option Period.

          (b) If the Participating Investors do not elect to sell the full
amount of Stock which they are entitled to sell pursuant to Section 6(a), the
Selling Founder shall be entitled to sell to the Proposed Transferee, according
to the terms set forth in the Notice, that number of his Shares which equals the
difference between the amount of Stock desired to be purchased by the Proposed
Transferee and the number of Shares the Participating Investors wish to sell, in
each case on a common equivalent basis.

          (c) If the Selling Founder wishes to sell or otherwise transfer any of
his Shares at a price per Share which differs from that set forth in the Notice,
upon terms different from those previously offered to the Corporation and the
Investors, or more than 60 days after the expiration of the Option Period, then,
as a condition precedent to such transaction, such Shares must first be offered
to the Corporation and the Investors on the same terms and conditions as given
the Proposed Transferee, and the Investors must first be offered the opportunity
to participate in such transaction, in accordance with the procedures and time
periods set forth above.

     7.   Permitted Transfers.
          -------------------

          (a) Subject to the provisions of Section 7(b) and Section 8, the
Corporation's and the Investors' right of first refusal and the Investors' right
of co-sale described in Sections 4 through 6 shall not apply to:  (i) any
transfer of Shares by a Founder by gift or bequest or through inheritance to, or
for the benefit of, any member or members of such Founder's immediate family;
(ii) any transfer of Shares by an Founder to a trust (A) in respect of which
such Founder serves as trustee, provided that the trust instrument governing
such trust shall provide that such Founder, as trustee, shall retain sole and
exclusive control over the voting and disposition of such Shares until the
termination of this Agreement or (B) for the benefit solely of any member or
members of such Founder's immediate family; (iii) any sale or transfer of Shares
to the Corporation; (iv) any underwritten public offering of Common Stock
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act"); and (v) with respect to sales or other
transfers of up to an aggregate of the following number of shares (as adjusted
to reflect any stock split, stock dividend, combination of shares or other

                                      -4-
<PAGE>

similar transaction), but subject in any case to the restrictions set forth in
Section 8:  (A) in the case of each of Koster and Masterson, 130,000 Shares; and
(B) in the case of Patterson, 50,000 Shares;

          (b) In the event of any sale or transfer described in clauses (i) or
(ii) of Section 7(a), the transferee of the Shares shall hold the Shares so
acquired subject to all the restrictions imposed by this Agreement and shall be
deemed a Founder for all purposes hereof, and as a condition to such transfer,
any such transferee shall, at the request of the Corporation or any Investor,
execute and deliver a written instrument agreeing to be bound by the provisions
of this Agreement.

     8.   Consent of the Corporation to Transfer.  As a condition to selling or
          --------------------------------------
otherwise transferring any Shares proposed to be sold or transferred by the
Selling Founder and any Participating Investor to any Proposed Transferee, other
than a sale or transfer described in clause (iii) or (iv) of Section 7(a), the
Selling Founder shall have obtained the written consent to such transfer by the
Board of Directors of the Corporation by majority vote at a meeting or by
unanimous consent in lieu of a meeting.  Such consent shall not be unreasonably
withheld, and shall be based on the Board of Directors' determination, after
such inquiry as it deems appropriate, but within thirty days of the date of the
Selling Founder's notice to the Corporation under Section 3, that the Proposed
Transferee is not a competitor of the Corporation and is not otherwise an
inappropriate investor in the Corporation.  In the event the Selling Founder
disagrees with such determination, and the Board of Directors and the Selling
Founder are unable to resolve the disagreement, an independent third party
selected and agreed upon by the Board of Directors and the Selling Founder shall
arbitrate and finally resolve the disagreement.

     9.   Lock-up.  Each Founder agrees that upon the request of the Corporation
          -------
or the underwriters managing an underwritten offering of the Corporation's
securities, such Founder will not sell, make any short sale or loan of, grant
any option for the purchase of, or otherwise dispose of any Shares held by him
without the prior written consent of the Corporation or such underwriters, as
the case may be, for a period of up to 180 days from effective date of the
applicable registration statement.

     10.  Sale or Transfer in Violation of this Agreement.  If any sale or other
          -----------------------------------------------
transfer of Shares is made or attempted in violation of any provision of this
Agreement, or if any Shares are not offered to the Corporation or the Investors
as required hereby, the Corporation and the Investors, as the case may be, shall
have the right to purchase such Shares from the owner thereof or his transferee
at any time before or after the transfer, as herein provided.  In addition to
any other legal or equitable remedies which it or they may have, the Corporation
and the Investors may enforce their respective rights hereunder by actions for
specific performance (to the extent permitted by law).  The Corporation shall
not be required (i) to transfer on its books any Shares or other Stock which has
been sold or transferred in violation of any provision of this Agreement or (ii)
to treat as the owner of such Shares or Stock, or to pay dividends to, any
transferee to whom any such Shares or Stock have been so sold or transferred.
If a Founder becomes obligated to sell any Shares to the Corporation under this
Agreement and fails to deliver such Shares in accordance with the terms of this
Agreement, the Corporation may, at its option, in addition to all other remedied
it may have, send to such Founder the purchase price for such

                                      -5-
<PAGE>

Shares as is herein specified and cancel on its books the certificate or
certificates representing the Shares to be sold. Thereafter, all of the
Founder's rights in and to such Shares shall terminate.

     11.  Disposition of Shares.  Any Shares that the Corporation elects to
          ---------------------
purchase hereunder may be disposed of by it in such manner as it deems
appropriate with or without restrictions on the transfer thereof, and the
Corporation may require their transfer to a nominee or designee as part of any
purchase of the Shares from the Founders.

     12.  Restrictive Legend.  All certificates representing Shares held by the
          ------------------
Founders which are subject to this Agreement shall have affixed thereto a legend
in substantially the following form, in addition to any other legends that may
be required by the Corporation in connection with compliance with federal or
state securities laws or otherwise:

          "The shares of stock represented by this certificate are
          subject to restrictions on transfer and/or an option to
          purchase set forth in a Stock Restriction Agreement between
          the Corporation and the registered owner of the shares
          represented by this certificate (or his predecessor in
          interest). The Corporation will furnish a copy of such
          agreement to the holder of this certificate upon written
          request without charge."

The Founders shall cause such legend to be affixed to any of such certificates
not so legended.

     13.  Term.  This Agreement shall terminate upon the closing of a firm
          ----
commitment underwritten public offering of Common Stock pursuant to an effective
registration statement under the securities Act in which (i) the public offering
price per share is not less than $4.50 (appropriately adjusted to take account
of any stock split, stock dividend, combination of shares or similar event) and
(ii) the aggregate gross proceeds to the Corporation are not less than
$10,000,000.

     14.  Specific Enforcement.  Each Founder expressly agrees that a violation
          --------------------
of this Agreement by such Founder could not be adequately compensated by money
damages alone and that the Investors and the Corporation will be irreparably
damaged if this Agreement is not specifically enforced.  Upon a breach or
threatened breach of the terms, covenants and/or conditions of this Agreement by
any Founder, the Investors and the Corporation shall, in addition to all other
remedies, each be entitled to a temporary or permanent injunction, and/or a
decree for specific performance, in accordance with the provisions hereof.

     15.  Other Agreements.  The restrictions on the Founders' right to dispose
          ----------------
of their Shares pursuant to this Agreement are in addition to and to be
construed consistently with the Founders' rights and obligations (including
restrictions on the Founders' right to dispose of shares of the Corporation's
capital stock) contained in any other agreement relating to restrictions on the
transferability of such Shares that the Founders execute before, on, or after
the date hereof; provided, that this Agreement shall supersede and replace (i)
the Stock Restriction Agreement dated October 16, 1995 between the Corporation
and Nola E. Masterson, which shall

                                      -6-
<PAGE>

no longer be of any force or effect, and (ii) the form of Stock Restriction
Agreement attached to the outstanding options to purchase Common Stock held by
Koster and Patterson.

     16.  Waiver, Modification and Termination.  No provision of this Agreement
          ------------------------------------
shall be deemed to have been waived by the corporation or any Investor in the
absence of a written agreement executed by such party with respect to such
waiver.  This Agreement may be modified or terminated only with the written
consent of the Founders, the Corporation, and the holders of a majority in
voting power of the Shares then held by the Investors.

     17.  Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     18.  Binding Effect; Assignment.  This Agreement shall be binding upon the
          --------------------------
parties hereto and their heirs, legal representatives, successors and assigns.
The rights and obligations of the Founders hereunder may not be assigned or
delegated without the written consent of the Corporation.

     19.  Notices.  All notices, requests, consents, deliveries and other
          -------
communications hereunder shall be in writing and shall be delivered in person or
duly sent by first class mail, postage prepaid, or by any internationally
recognized express courier service, to the Corporation at its principal place of
business, and to the Investors and the Founders at their respective last known
address or at their respective address, if any, appearing on the books of the
Corporation.

     20.  Severability.  If any provision of this Agreement shall be held to be
          ------------
illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

     21.  Governing Law.  This Agreement shall be governed by, and construed and
          -------------
enforced in accordance with, the substantive law of The Commonwealth of
Massachusetts, without regard to its principles of conflicts of laws.

     22.  Captions.  Captions are for convenience only and are not deemed to be
          --------
part of this Agreement.

     23.  Counterparts.  This Agreement may be executed in one or more
          ------------
counterparts, each of which shall be deemed an original and all of which
together shall constitute a single instrument.  Each such counterpart may
contain one or more signature pages.

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

<PAGE>

                         REGISTRATION RIGHTS AGREEMENT


     This Registration Rights Agreement is entered into as of December 22, 1995
by and among Sequenom, Inc., a Delaware corporation (the "Corporation"), and the
purchasers of shares of the Corporation's Series B Convertible Preferred Stock,
par value $.001 per share (the "Series B Preferred Stock"), pursuant to the
Series B Convertible Preferred Stock Purchase Agreement dated as of the date
hereof (the "Purchase Agreement"), including any Additional Investors as defined
in the Purchase Agreement (such purchasers of Series B Preferred Stock being
hereinafter sometimes referred to individually as an "Investor" and collectively
as the "Investors").

     WHEREAS, the Corporation has previously issued to certain of the Investors
certain shares of the Corporation's Series A Convertible Preferred Stock, $.001
par value per share (the "Series A Preferred Stock" and, together with the
Series B Preferred Stock, the "Preferred Stock");

     WHEREAS, the Corporation now wishes to sell to the Investors certain shares
of its Series B Preferred Stock;

     WHEREAS, the Preferred Stock is convertible into shares of the
Corporation's Common Stock, par value $.001 per share ("Common Stock"); and

     WHEREAS, as a condition to entering into the Purchase Agreement, the
Investors have required that the Corporation execute this Agreement to provide
the Investors rights to register the shares of Common Stock into which their
Preferred Stock is convertible;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
hereinafter set forth, the parties hereto agree as follows:

     1.   Definitions.  As used in this Agreement, the following terms shall
          -----------
have the following meanings:

          (a) The term "Act" means the Securities Act of 1933, as amended;

          (b) The term "Holder" means any Investor and any other person or
entity holding Registrable Securities to whom the registration rights granted in
this Agreement have been transferred pursuant to Section 14 hereof;

     (c) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement; and

     (d) The term "Registrable Securities" means (1) the Common Stock issuable
upon conversion of the Preferred Stock, (2) Common Stock purchased by an
Investor pursuant to Section 8.1 of the Purchase Agreement (or Common Stock for
or into which New Securities
<PAGE>

(as therein defined) purchased by the Investor pursuant to such Section 8.1 may
be exercised or converted) or pursuant to the Stock Restriction Agreement
referred to in Section 6.6 of the Purchase Agreement, and (3) any Common Stock
of the Corporation issued as a dividend or other distribution with respect to,
or in exchange or in replacement of, such Preferred Stock or Common Stock.

     In addition, for purposes of all calculations and notices under this
Agreement, and all other provisions of this Agreement where the context permits,
the term "Registrable Securities" shall include securities issuable upon
conversion of the Preferred Stock, a holder of the Preferred Stock shall be
deemed the Holder of such securities and such securities shall be deemed
outstanding Registrable Securities hereunder.  Notwithstanding the foregoing,
nothing in this Agreement shall require the Corporation actually to register any
shares of the Preferred Stock.

     2.   Request for Registration.  If at any time after the earlier of (i) the
          ------------------------
first underwritten public offering of securities for the account of the
Corporation, and (ii) the date three (3) years from the date hereof, the
Corporation shall receive a written request (specifying that it is being made
pursuant to this Section 2) from the Holder or Holders at least fifty percent
(50%) of the then outstanding Registrable Securities that the Corporation file a
registration statement under the Act, or a similar document pursuant to any
other statute then in effect corresponding to the Act, covering the registration
of at least the lesser of (i) at least twenty-five percent (25%) of the then
outstanding Registrable Securities and (ii) Registrable Securities the expected
price to the public of which equals or exceeds $10,000,000, then the Corporation
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that Holders have requested be
registered to be registered under the Act.

     Notwithstanding the foregoing, (a) the Corporation shall not be obligated
to effect a registration pursuant to this Section 2 during the period starting
with the date sixty (60) days prior to the Corporation's estimated date of
filing of, and ending on a date six (6) months following the effective date of,
a registration statement pertaining to an underwritten public offering of
securities for the account of the Corporation, provided that the Corporation is
actively employing in good faith its best efforts to cause such registration
statement to become effective and that the Corporation's estimate of the date of
filing such registration statement is made in good faith; (b) the Corporation
shall not be obligated to effect a registration pursuant to this Section 2
within six (6) months after the effective-date of a prior registration under
such Section; (c) if the Corporation shall furnish to the Holders a certificate
signed by the President of the Corporation stating that in the good faith
judgment of the Board of Directors it would be seriously detrimental to the
Corporation or its shareholders for a registration statement to be filed in the
near future, then the Corporation's obligation to use its best efforts to file a
registration statement shall be deferred for a period not to exceed three (3)
months; and (d) the Corporation may postpone a registration pursuant to this
election for such period of time as may be required to permit the use of regular
audited year-end financial statements with supplemental short period figures for
a period not exceeding six (6) months unless the Holders agree to bear the costs
of any special audit.

                                      -2-
<PAGE>

     The Corporation shall not be obligated to effect more than two (2)
registrations pursuant to this Section 2.  Any request for registration under
this Section 2 must be for a firm commitment underwritten public offering to be
managed by an underwriter or underwriters of recognized national standing
reasonably acceptable to the Corporation.

     3.   Corporation Registration.  Subject to Section 8 of this Agreement, if
          ------------------------
at any time the Corporation proposes to register any of its Common Stock under
the Act in connection with the public offering of such securities for its own
account or for the accounts of other shareholders, solely for cash on a form
that would also permit the registration of the Registrable Securities, the
Corporation shall, each such time, promptly give each Holder written notice of
such determination. Upon the written request of any Holder given within thirty
(30) days after mailing of any such notice by the Corporation, the Corporation
shall, subject to the limitations set forth in Section 8(a), use its best
efforts to cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested be registered.

     4.   Obligations of the Corporation.  Whenever required under
          ------------------------------
Section 2, 3, or 11 to use its best efforts to effect the registration of any
Registrable Securities, the Corporation shall, as expeditiously as reasonably
possible:

     (a)  Prepare and file with the Securities and Exchange Commission ("SEC") a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a so-
called "shelf registration the Corporation shall in no event be obligated to
cause any such registration to remain effective for more than one hundred eighty
(180) days.

     (b)  Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

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

     (d)  Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Corporation
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such

                                      -3-
<PAGE>

expenses shall be payable by selling shareholders pro rata, to the extent
required by such jurisdiction.

     (e)  Provide a transfer agent for the Common Stock no later than the
effective date of the first registration of any Registrable Securities.

     5.   Furnish Information.  It shall be a condition precedent to the
          -------------------
obligations of the Corporation to take any action pursuant to this Agreement
that the Holders shall furnish to the Corporation such information regarding
them, the Registrable Securities held by them, and the intended method of
disposition of such securities as the Corporation shall reasonably request and
as shall be required in connection with the action to be taken by the
Corporation.

     6.   Expenses of Demand Registration.  All expenses incurred in connection
          -------------------------------
with registrations pursuant to Section 2 (excluding underwriters, discounts and
commissions), including, without limitation, all registration and qualification
fees, printers, and accounting fees, fees and disbursements of counsel for the
Corporation, and the reasonable fees and disbursements of one special counsel
for the selling Holders, shall be borne by the corporation.

     7.   Corporation Registration Expenses.  All expenses (excluding
          ---------------------------------
underwriters, discounts and commissions) incurred in connection with a
registration pursuant to Section 3 (other than a registration on Form S-3 filed
pursuant to Section 11), including, without limitation, any additional
registration and qualification fees and any additional fees and disbursements of
counsel to the Corporation that result from the inclusion of securities held by
the Holders in such registration and the reasonable fees and disbursements of
one special counsel for the selling stockholders, shall be borne by the
Corporation; provided, however, that if the registration is of exclusively a
secondary offering, the holders shall bear their proportionate share of the
expenses incurred in connection with any registration (provided all shareholders
registering shares thereunder bear their proportionate share of expenses),
except expenses which the Corporation would have incurred whether or not the
securities held by the Holders were included in such registration (including,
without limitation, the expense of preparing normal audited or unaudited
financial statements).

     8.   Underwriting Requirements.
          -------------------------

     (a)  In connection with any offering involving an underwriting of shares
being issued by the Corporation, the Corporation shall not be required under
Section 3 to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Corporation and the underwriters selected by it, and then only in
such quantity as will not, in the reasonable opinion of the underwriters,
jeopardize the success of the offering by the Corporation.  If the total amount
of securities that all Holders request to be included in an underwritten
offering exceeds the amount of securities that the underwriters reasonably
believe compatible with the success of the offering, the Corporation shall only
be required to include in the offering so many of the securities of the selling
Holders as the underwriters reasonably believe will not jeopardize the success
of the offering (the securities so included to be apportioned pro rata among the
selling Holders according to the total amount of securities owned by said
selling Holders, or in such other proportions as shall

                                      -4-
<PAGE>

mutually be agreed to by such selling Holders), provided that in the case of an
offering involving shares being issued by the Corporation, no such reduction
shall be made with respect to any securities offered by the Corporation for its
own account, and provided further that no securities of any shareholder who is
not a Holder shall be included in such offering, other than securities of
shareholders who have initiated such registration pursuant to the exercise of
contractual rights to do so, unless all securities which the Holders have
requested to be included are included on a pro rata basis with the securities of
any other shareholders who have a contractual right to include their securities
in such offering.

     (b)  With respect to any underwriting of shares to be registered under
Section 2, or an underwriting of shares to be registered under Section 11 if the
Holders of a majority of the then outstanding Registrable Securities have
requested registration thereunder, such Holders shall have the right to
designate the managing underwriter or underwriters, subject to the consent of
the Corporation.  In all other circumstances under such Sections and in
connection with registrations under Section 3, the Corporation shall have the
right to designate the managing underwriter or underwriters; subject to the
consent of the Holders of a majority of the Registrable Securities participating
in the underwriting.  In any such case, such consent shall not be unreasonably
withheld or delayed.

     9.   Delay of Registration.  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 Agreement.

     10.  Indemnification.  In the event any Registrable securities are included
          ---------------
in a registration statement under this Agreement:

     (a)  To the extent permitted by law, the Corporation will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person, if any, who
controls such Holder or underwriter within the meaning of the Act, against any
losses, claims, damages or liabilities, joint or several, to which they 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
on any untrue or alleged untrue statement of any material fact contained in such
registration statement, including, without limitation, any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, 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 or arise out of any
violation by the Corporation of any rule or regulation promulgated under the Act
applicable to the Corporation and relating to action or inaction required of the
Corporation in connection with any such registration; and will reimburse each
such Holder, such underwriter, or controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action, provided, however,
that the indemnity agreement contained in this Section 10(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 corporation (which
consent shall not be unreasonably withheld or delayed) nor shall the Corporation
be liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon an

                                      -5-
<PAGE>

untrue statement or alleged untrue statement or omission or alleged omission
made in connection with such registration statement, preliminary prospectus,
final prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person.

     (b)  To the extent permitted by law, each Holder requesting or joining in a
registration will indemnify and hold harmless the Corporation, each of its
directors, each of its officers who has signed the registration statement, each
person, if any, who controls the Corporation within the meaning of the Act, and
any underwriter for the Corporation (within the meaning of the Act) against any
losses, claims, damages or liabilities to which the corporation or any such
director, officer, controlling person or underwriter may become subject, under
the Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, 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,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such
registration statement, preliminary prospectus or final prospectus, or
amendments or supplements thereto, in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and will reimburse the Corporation or any such director,
officer, controlling person or underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 10(b) 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 such Holder (which consent shall
not be unreasonably withheld) and provided further that no Holder shall have any
liability under this Section 10(b) in excess of the net proceeds actually
received by such Holder in the relevant public offering.

     (c)  Promptly after receipt by an indemnified party under this Section 10
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 10, notify the indemnifying party in writing of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties. The failure to notify an indemnifying party
promptly, of the commencement of any such action, if prejudicial to his ability
to defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 10, but the omission so to notify the
indemnifying party will not relieve him of any liability that he may have to any
indemnified party otherwise than under this Section 10.

     11.  Registrations on Form S-3.
          -------------------------

     (a)  If (i) the Corporation shall receive a written request (specifying
that it is being made pursuant to this Section 11) from the Holder or Holders of
at least twenty-five percent (25%) of the then outstanding Registrable
Securities that the Corporation file a registration statement on Form S-3 (or
any successor form to Form S-3 regardless of its designation) for a public
offering of shares of the Registrable Securities the reasonably anticipated
aggregate price to the public of which would exceed Two Million Dollars
($2,000,000), and (ii) the corporation is a registrant entitled to use Form S-3
to register such shares, then the Corporation shall use its best efforts to
cause such shares to be registered on Form S-3 (or any successor form to Form
S-3).

     (b)  All expenses (excluding underwriters' discounts and commissions)
incurred in connection with the first two registrations requested pursuant to
Section 11(a), including, without limitation, all registration, qualification,
printing, and accounting fees, and fees and disbursements of one special counsel
to the selling Holder or Holders and counsel to the Corporation, shall be borne
by the Corporation.  All such expenses for registrations pursuant to Section
11(a) after the first two such registrations shall be borne by the Corporation,
except that the selling Holders shall pay all fees of their legal counsel, if
any, in connection therewith.

     (c)  Holders' rights to registration under this Section 11 are in addition
to, and not in lieu of, their rights to registration under Sections 2 and 3 of
this Agreement.

     12.  Reports Under Securities Exchange Act of 1934.  With a view to making
          ---------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Corporation to the public without registration, the
corporation agrees to use its best efforts to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Corporation;

     (b)  file with the SEC in a timely manner all reports and other documents
required of the Corporation under the Act and the Securities Exchange Act of
1934, as amended (the "1934 Act"); and

     (c)  furnish to any Holder forthwith upon request a written statement by
the Corporation that it has complied with the reporting requirements of Rule 144
(at any time after ninety (90) days after the effective date of said first
registration statement filed by the Corporation), and of the Act and the 1934
Act (at any time after it has become subject to such reporting requirements), a
copy of the most recent annual or quarterly report of the Corporation, and such
other reports and documents so filed by the Corporation as may be reasonably
requested in availing any such holder to take advantage of any rule or
regulation of the SEC permitting the selling of any such securities without
registration.

     13.  Limitations in Connection with Future Grants of Registration Rights.
          -------------------------------------------------------------------
Without the prior written consent of the Holder or Holders of a majority of the
then outstanding Registrable Securities issued or issuable upon conversion of
the Series B Preferred Stock, the Corporation shall not grant rights to cause
the Corporation to register any of its securities to any person or entity.

     14.  Transfer of Registration Rights.  The registration rights of any
          -------------------------------
Investor (and of any permitted transferee of any Investor or its permitted
transferees) under this Agreement with respect to any shares of Registrable
Securities may be transferred to any Affiliate of such Investor or such
permitted transferee, or to any transferee who acquires (otherwise than in a
registered public offering) at least five percent (5%) of the Registrable
Securities held or acquired as of the date hereof by such Investor, provided,
however, that the Corporation is given written notice by the Holder at the time
of such transfer stating the name and address of the transferee and identifying
the securities with respect to which the rights under this Agreement are being
assigned. For such purpose, an "Affiliate" of any Investor (or any such
transferee) means any partner of such Investor (or transferee) if it is a
partnership, or any person or entity that, directly or indirectly, through one
or more intermediaries, controls or is controlled by, or is under common control
with, such Investor or transferee.

     15.  Mergers, Etc.  The Corporation shall not, directly or indirectly,
          ------------
enter into any merger, consolidation or reorganization in which the Corporation
shall not be the surviving corporation unless the proposed surviving corporation
shall, prior to such merger, consolidation or reorganization, agree in writing
to assume the obligations of the Corporation under this Agreement, and for that
purpose references hereunder to "Registrable Securities" shall be deemed to be
references to the securities which the Holders would be entitled to receive in
exchange for Registrable Securities under any such merger, consolidation or
reorganization; provided, however, that the provisions of this Agreement shall
not apply in the event of any merger, consolidation or reorganization in which
the Corporation is not the surviving corporation if the Holders of Registrable
Securities are entitled to receive in exchange therefor (i) cash, or (ii)
securities of the acquiring corporation which may be immediately sold to the
public without registration under the Act.

     16.  Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such

Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     17.  Notices.  All notices, requests, consents and other communications
          -------

                                VOTING AGREEMENT

     Agreement made as of December 22, 1995 by and among Sequenom, Inc., a
Delaware corporation (the "Corporation"); Hubert Koster, Nola E. Masterson and
Robert E. Patterson (the "Founders"); TVM Techno Venture Enterprises No. II
Limited Partnership, TVM Intertech Limited Partnership TVM Zweite Beteiligung-
U.S. Limited Partnership, TVM Eurotech Limited Partnership, TVM Techno Venture
Investors No. 1 Limited Partnership and *** (the "Original Investors"); the
purchasers of shares of the Corporation's Series B Convertible Preferred Stock,
$.001 par value per share ("Series B Preferred Stock"), pursuant to the Series B
Convertible Preferred Stock Purchase Agreement dated as of the date hereof (the
"Purchase Agreement"), including Boston University Nominee Partnership ("BU")
and any Additional Investors as defined in the Purchase Agreement (all such
purchasers of Series B Preferred Stock under the Purchase Agreement being
referred to as the "Investors," and all such Founders, Original Investors and
Investors being referred to as the "Stockholders").

                                   AGREEMENT
                                   ---------

     In consideration of the mutual covenants herein contained, the parties
hereto agree as follows:

     1.   Board of Directors.  The Stockholders agree to vote all shares of the
          ------------------
Corporation's Common Stock, $.001 par value per share ("Common Stock"), Series A
Convertible Preferred Stock, $.001 par value per share ("Series A Preferred
Stock"), Series B Preferred Stock and any other class of voting security of the
Corporation (the "Shares") now or hereafter owned or controlled by them, and
otherwise to use their respective best efforts as stockholders of the
Corporation, to set the number of directors of the Corporation at seven and to
elect as directors, on the date of this Agreement and in any subsequent election
of directors of the Corporation: the Chief Executive Officer of the Corporation,
who shall initially be Randall R. Lunn; one person designated by the Founders,
who shall initially be Hubert Koster; one person designated by the Original
Investors, who shall initially be Helmut Schuhsler; one person designated by BU,
who shall initially be William Golden; one person designated by the Investors,
who shall be designated and elected after the date of this Agreement; and two
persons who are not employees of the Corporation, who have experience in the
Corporation's industry and who are reasonably acceptable to a majority of the
other directors, and who shall initially be Nola E. Masterson and Ernst Gunter
Afting.

     Any party or parties making director designations (a "Designating Party")
shall furnish written notice to the other parties at least 10 days prior to any
election of directors of their director-designee or director-designees.  In the
absence of such notice, the director-designee or director-designees of such
Designating Party then serving and previously designated shall be reelected if
still eligible to, serve as provided herein.  No party hereto shall vote to
remove any member of the Board of Directors designated in accordance with the
aforesaid procedure unless the Designating Party who designated such director so
votes, and if such Designating party so votes then the other parties shall
likewise so vote.

     Any vacancy on the Board of Directors created by the resignation, removal,
incapacity, or death of any person designated under this Section 1 shall be
filled by another person designated

*** Portions of this page have been omitted pursuant to a request for
Confidential Treatment and filed separately with the Commission.


<PAGE>

by the original Designating Party. The Stockholders shall vote their respective
Shares in accordance with such new designation, and any such vacancy shall not
be filled in the absence of a new designation by the original Designating Party.

     This Section 1 shall terminate and be of no further force and effect upon
the closing of a firm commitment underwritten public offering of Common Stock of
the Corporation pursuant to an effective registration statement under the
Securities Act of 1933, as amended, in which the aggregate gross proceeds to the
Corporation from such offering are not less than $10,000,000 and the offering
price per share is not less than $4.50, appropriately adjusted to take account
of any stock split, stock dividend, combination of shares or similar event.

     In the event that any Designating Party (or its or their respective
partners, stockholders and affiliates) owns, in the aggregate, fewer than
200,000 shares of the Corporation's Common Stock, subject to adjustment for
stock splits, stock dividends, combinations of shares and similar events, such
Designating Party's right to make designations under this Section 1 shall
terminate, and the obligation of the other parties under this Section 1 to vote
for any members of the Board of Directors designated by such Designating Party
shall terminate, but all other obligations of all parties hereunder shall
continue unless otherwise terminated.  For purposes of this paragraph, in
determining the number of shares of Common Stock owned by a Designating Party,
ownership by such Designating Party of shares of Series A Preferred Stock and
Series B Preferred Stock shall be deemed to be ownership by it of that number of
shares of Common Stock into which such shares of Series B Preferred Stock are
convertible.

     In the event that any group of Stockholders constituting a Designating
Party cannot agree upon a director-designee, the identity of the director-
designee of such Designating Party shall be determined by a plurality in voting
power of the outstanding capital stock of the Corporation held by such
Stockholders.

     In the event that BU shall fail to participate in any future equity
financing for the Corporation for its full pro rata share of the portion of such
financing purchased by the then-existing institutional investors in the
Corporation, (i) BU's right to make designations under this Section 1 shall-
terminate, and the obligation of the other parties under this Section 1 to vote
for any member of the Board of Directors designated by BU shall terminate, but
all other rights and obligations of all parties hereunder, including the right
of BU to participate as an Investor in the designation of any person to the
Board of Directors, shall continue unless otherwise terminated; and (ii)
thereafter the Investors shall have the right to designate two persons for
election to the Board of Directors.

     2.   Director Indemnification.  In the event that any director contemplated
          ------------------------
by this Agreement shall be made or threatened to be made a party to any action,
suit or proceeding with respect to which he may be entitled to indemnification
by the Corporation pursuant to its Certificate of Incorporation, By-Laws or
otherwise, he shall be entitled to be represented in such action, suit or
proceeding by counsel of his choice and the expenses of such representation
shall be reimbursed by the Corporation to the extent provided in or authorized
by said Certificate of Incorporation or other provision and permitted by
applicable law.

                                      -2-
<PAGE>

     The Corporation and the Stockholders agree not to take any action to amend
any provision of the Certificate of Incorporation or By-Laws of the Corporation
relating to indemnification of directors, as presently in effect, without the
prior written consent of a majority in voting power of the Investors.

     3.   Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" and a
"Stockholder" for all purposes of this Agreement.

          4.   Notices.  All notices, requests, consents and other
               -------
communications hereunder to any party shall be deemed to be sufficient if
contained in a written instrument delivered in person or duly sent by first
class mail, postage prepaid, or by any internationally recognized express
courier service, addressed to such party at the address set forth below or such
other address as may hereafter be designated in writing by the addressee to the
addressor listing all parties:

          (i)  if to the Corporation, to:

               Sequenom, Inc.
               c/o TVM Techno Venture Management
               101 Arch Street
               Suite 1950
               Boston, MA 02110
               Attention: President

               with a copy to:

               Foley, Hoag & Eliot
               One Post office Square
               Boston, Massachusetts 02109

          (ii) if to the Stockholders, to their respective last known address or
               their respective address, if any, appearing in the books of the
               Corporation.

     5.   Assignment; Binding Effect.  No Designating Party may assign its or
          --------------------------
their rights hereunder. Subject to termination or partial termination as
provided in Section 1, this Agreement shall be binding on the parties hereto and
their respective legal representatives, successors and permitted assigns and on
the transferees of any Shares now owned or hereafter acquired by them.

     6.   Entire Agreement; Amendment and Waiver.  This Agreement contains the
          --------------------------------------
sole and entire understanding of the parties with respect to its subject matter
and supersedes all prior negotiations, commitments, agreements and
understandings heretofore had among any of them with respect thereto. Without
limiting the generality of the foregoing, this Agreement supersedes

                                      -3-
<PAGE>

and replaces the Voting Agreement among the Founders and the Original Investors
dated May 26, 1994, which shall no longer have any force or effect. This
Agreement may not be changed or terminated or any performance or condition
waived, in whole or in part, except by the written agreement of the Corporation
and Stockholders or transferees of their rights hereunder holding two-thirds in
voting power of the Shares held by the Founders, two-thirds in voting power of
the Shares held by the Original Investors, eighty-five percent (85%) in voting
power of the Shares held by the Investors, and two-thirds in voting power of the
Shares held by the Stockholders or such transferees. A waiver on one occasion
shall not constitute a waiver on any further occasion.

     7.   Counterparts.  This Agreement may be executed in more than one
          ------------
counterpart, each of which shall be deemed to be an original and which,
together, shall constitute one and the same instrument. Any such counterpart may
contain one or more signature pages.

     8.   Applicable Law.  This Agreement shall be governed by, and construed
          --------------
and enforced in accordance with, the substantive laws of The Commonwealth of
Massachusetts, without regard to its principles of conflicts of laws.

     9.   Legend.  Each certificate for Shares shall bear a legend stating in
          ------
substance as follows, and each of the Stockholders shall cause its certificates
to be so legended promptly after the execution and delivery of this Agreement:

     The shares of stock represented by this certificate are subject to the
     terms and provisions of a Voting Agreement dated December 22, 1995 among
     the Corporation and certain stockholders of the Corporation.  The
     Corporation will furnish a copy of the Voting Agreement to the holder
     hereof upon written request and without charge.

To the Persons listed in the Schedule
of Investors to the Series B
Convertible Preferred Stock Purchase
Agreement dated as of December 22, 1995

Gentlemen:

     We are counsel to Sequenom, Inc., a Delaware corporation (the
"Corporation").  This opinion is rendered to you pursuant to Section 6.5 of the
Series B Convertible Preferred Stock Purchase Agreement (including the exhibits
thereto, the "Agreement") dated as of December 22, 1995, among the Corporation
and each of you relating to the issuance and sale by the Corporation to you of
2,333,333 shares (the "Initial Shares") of its Series B Convertible Preferred
Stock, par value $.001 per share (the "Transaction").  Capitalized terms used
herein and not otherwise defined herein shall have the meanings assigned to such
terms in the Agreement.

     In connection with our rendering this opinion, we have reviewed (i) the
Certificate of Incorporation and By-Laws of the Corporation, each as amended to
date; (ii) a certificate issued by the Secretary of State of the State of
Delaware on December 15, 1995, with respect to the due incorporation, legal
existence and good standing of the Corporation in the State of Delaware (the
"Legal Existence Certificate"); (iii) a certificate issued by the Secretary of
State of The Commonwealth of Massachusetts on December 15, 1995, with respect to
the qualification of the Corporation to do business in Massachusetts (the
"Foreign Qualification Certificate"); (iv) counterparts of the Agreement and the
related Registration Rights Agreement of even date herewith (the "Registration
Rights Agreement"); and (v) originals or copies, certified or otherwise,
identified to our satisfaction, of such other documents, certificates,
instruments and corporate records that we considered necessary for the purposes
of this opinion.

     In rendering the opinion expressed herein, we have also examined and have
relied completely as to matters of fact upon the representations and warranties
made by the Corporation and each of you in the Agreement, the Registration
Rights Agreement and the other agreements, instruments and documents delivered
in connection with the Initial Closing; and we have assumed the completeness and
accuracy of all factual matters described in such representations and
warranties.

     We have not, except as specifically noted above, made any independent
review or investigation of facts relating to the Corporation, including but
without limiting the generality of the foregoing, any investigation as to the
existence of any actions, suits or proceedings pending or threatened against the
Corporation or notes, indentures, mortgages, leases, contracts, instruments,
documents, agreements, judgments, injunctions, orders, writs or decrees to which

<PAGE>

To the Persons listed in the Schedule
of Investors to the Series B
Convertible Preferred Stock Purchase
Agreement dated as of December 22, 1995

the Corporation is a party, which are binding upon the Corporation or which
might result in the imposition of any lien or other encumbrance on any asset of
the Corporation.

     We have assumed the authenticity and completeness of all documents
furnished to us as originals, the genuineness of all signatures, the legal
capacity of natural persons, and the conformity to the originals of all
documents furnished to us as copies.

     In rendering the opinions expressed in paragraph 1 below with respect to
the due incorporation, legal existence and good standing of the Corporation in
Delaware and in paragraph 2 below with respect to the qualification of the
Corporation to do business in The Commonwealth of Massachusetts, we have relied
solely on the Legal Existence Certificate and the Foreign Qualification
Certificate, respectively.

     You have not asked us to pass upon your power and authority to enter into
the Agreement or the Registration Rights Agreement.  Accordingly, for the
purposes of this opinion, we have assumed that you have all requisite power and
authority to enter into the Agreement and the Registration Rights Agreement and
to effect the transactions contemplated thereby, and that each of the Agreement
and the Registration Rights Agreement constitutes the valid and legally binding
obligation of all parties thereto other than the Corporation.

     We have made such examination of Massachusetts and federal Law and of the
General Corporation Law of Delaware as we deem necessary for the purposes of
this opinion.  We do not purport to pass herein on the laws of any state or
jurisdiction other than the United States of America and The Commonwealth of
Massachusetts, and as to its General Corporation Law only, the State of
Delaware.

     The opinions herein expressed are qualified to the extent that (i) the
validity or enforceability of any provisions of any agreement or instrument or
of any rights granted thereunder may be subject to or affected by any
bankruptcy, reorganization, insolvency, moratorium or similar law from time to
time in effect and relating to or affecting the rights or remedies of creditors
generally, (ii) the remedy of specific performance or any other equitable remedy
may be unavailable in any jurisdiction or may be withheld as a matter of
judicial discretion; and (iii) a court may apply equitable principles in
construing or enforcing the provisions of any agreement or instrument.

     The phrase "of which we have knowledge" means the actual knowledge of the
lawyer signing this opinion letter and the other lawyers in our office who have
had active involvement in negotiating the Transaction and preparing the
Agreement and the Registration Rights Agreement.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.   The Corporation is a corporation duly incorporated, validly existing
          and in good standing under the laws of the State of Delaware and has
          the requisite corporate power to carry on its business as it is
          currently being conducted.

Agreement dated as of December 22, 1995

     2.   The Corporation is qualified to do business in The Commonwealth of
          Massachusetts.

     3.   The execution and delivery of the Agreement and the Registration
          Rights Agreement and the performance by the Corporation of its
          obligations thereunder have been duly authorized by all necessary
          corporate action on the part of the Corporation and do not violate or
          cause any default under any provision of (i) the Corporation's
          Certificate of Incorporation or By-Laws, or (ii) except where any such
          violation or default would not have a material adverse effect on the
          Corporation, any note, indenture, mortgage, lease, contract or other
          instrument, document or agreement to which the Corporation is a party
          and of which we have knowledge, or any writ, injunction, order,
          judgment or decree of any court, administrative agency or other
          governmental body to which the Company is a party and of which we have
          knowledge.  Each of the Agreement and the Registration Rights
          Agreement constitutes a valid and legally binding obligation of the
          Corporation, enforceable against the Corporation in accordance with
          its terms; provided, however, that we express no opinion as to the
          enforceability of the indemnification provisions contained in Section
          10 of the Registration Rights Agreement.

     4.   The sale of Initial Shares to each of you is not required to be
          registered under the Securities Act of 1933 or the Massachusetts
          Uniform Securities Act.

     5.   Upon receipt by the Corporation of the purchase price therefor, the
          Initial Shares will be validly issued, fully-paid and non-assessable.

     6.   No authorization, consent, approval or other order of, declaration to,
          or filing with, any governmental agency or body is required to be made
          or obtained by the Corporation for or in connection with the valid and
          lawful authorization, execution and delivery by the Corporation of the
          Agreement and the Registration Rights Agreement, for or in connection
          with the valid and lawful authorization, issuance, sale and delivery
          of the Initial Shares or for or in connection with the valid and
          lawful authorization, reservation, issuance, sale and delivery of the
          Reserved Shares to be issued upon the conversion of the Initial
          Shares, except such exemptive filings, if any, as are required to be
          made under applicable securities laws.

                                        Very truly yours,

     SECTION 8.  Additional Agreements of the Corporation.
     ---------   ----------------------------------------

          8.1  Right of First Refusal.
               ----------------------

               (a) Subject to the limitations set forth in paragraph (i) of this
Section 8.1 and in Section 8.9, the Corporation hereby grants to each Investor,
each Series B Investor, each Founder, and any of their respective permitted
assignees described in paragraph (j) of this Section 8.1 (each a "Right Holder")
the right of first refusal to purchase, pro rata, all (or any part) of any New
Securities (as defined in this Section 8.1 (b)) that the Corporation may, from
time to time, propose to sell or issue.  Each such Right Holder's pro rata
share, for purposes of

                                      -13-
<PAGE>

this right of first refusal, is the ratio of (i) the number of shares of Common
Stock then held of record by, or issuable on conversion of Series C Preferred,
Series B Preferred or Series A Preferred (collectively, "Preferred Stock") then
held of record by, such Right Holder to (ii) the sum of the total number of
shares of the Common Stock issued and outstanding plus the total number of
shares of Common Stock issuable upon conversion of the Preferred Stock, in each
case at such time (the "Basic Amount").

          (b) "New Securities" shall mean any equity securities of the
Corporation, whether now authorized or not, and rights, options, or warrants to
purchase said equity securities, and securities of any type whatsoever that are,
or may become, convertible into said equity securities; provided, however, that
                                                        --------  -------
"New Securities" does not include (i) securities offered to the public pursuant
to a registration statement filed under the Securities Act, the gross proceeds
to the Corporation from the sale of which would equal or exceed $20,000,000;
(ii) securities issued pursuant to the acquisition of another corporation by the
Corporation by merger, purchase of substantially all of the assets, or other
reorganization whereby the Corporation acquires not less than 51 % of the voting
power of such corporation; (iii) up to 1,200,000 shares (appropriately adjusted
to take account of any stock split, stock dividend, combination of shares or the
like) of Common Stock (or related options) issued to employees, officers or
other persons performing services for the Corporation pursuant to any stock
offering, plan or arrangement approved by the Board of Directors of the
Corporation, which number may be adjusted upward by the affirmative vote of two-
thirds of the whole Board of Directors; (iv) securities issued in connection
with any stock split, stock dividend or recapitalization by the Corporation; (v)
shares of Common Stock issued upon conversion of the Shares or the Warrant
Shares; (vi) securities issuable upon exercise or conversion of any rights,
options, warrants or convertible securities outstanding on the date of this
Agreement; (vii) securities issued to any financial institution in connection
with a loan transaction approved by the Board of Directors of the Corporation;
(viii) securities issued to vendors or customers or to other persons in similar
commercial situations with the Corporation, provided such issuance is approved
by the Board of Directors of the Corporation; (ix) securities issued in
connection with obtaining lease financing, whether issued to a lessor, guarantor
or other person involved in the financing, provided such issuance is approved by
the Board of Directors of the Corporation; (x) the Additional Shares; or (xi)
any right, option or warrant to acquire any security convertible into securities
excluded from the definition of New Securities pursuant to clauses (i) through
(x) above.

          (c) The Corporation shall not issue, sell or exchange, agree to issue,
sell or exchange, or reserve or set aside for issuance, sale or exchange any New
Securities unless the Corporation shall deliver to each Right Holder a written
notice of any proposed or intended issuance, sale or exchange of New Securities
(the "Offer"), which Offer shall (i) identify and describe the New Securities,
(ii) describe the price and other terms upon which they are to be issued, sold
or exchanged, and the number or amount of the New Securities to be issued, sold
or exchanged, (iii) identify the persons or entities to which or with which the
New Securities are to be offered, issued, sold or exchanged and (iv) offer to
issue and sell to or exchange with such Right Holder (a) such Right Holder's
Basic Amount, and (b) any additional portion of the New Securities as such Right
Holder shall indicate it will purchase or acquire should the other Right Holders
subscribe for less than their Basic Amounts (the "Undersubscription Amount").
Each Right Holder shall have the right, for a period of 30 days following
delivery of the Offer, to

                                      -14-
<PAGE>

purchase or acquire, at a price and upon the other terms specified in the Offer,
the number or amount of New Securities described above. The Offer by its terms
shall remain open and irrevocable for such 30-day period.

          (d) To accept an Offer, in whole or in part, a Right Holder must
deliver a written notice to the Corporation prior to the end of the 30-day
period of the Offer, setting forth the portion of the Right Holder's Basic
Amount that such Right Holder elects to purchase and, if such Right Holder shall
elect to purchase all of its Basic Amount, the Undersubscription Amount (if any)
that such Right Holder elects to purchase (the "Notice of Acceptance"). If the
Basic Amounts subscribed for by all Right Holders are less than the total New
Securities, then each Right Holder who has set forth an Undersubscription Amount
in its Notice of Acceptance shall be entitled to purchase, in addition to the
Basic Amount subscribed for, the Undersubscription Amount it has subscribed for;
provided, however, that should the Undersubscription Amounts subscribed for
- -----------------
exceed the difference between the New Securities and the Basic Amounts
subscribed for (the "Available Undersubscription Amount"), each Right Holder who
has subscribed for any Undersubscription Amount shall be entitled to purchase
only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Right Holder bears to the total
Undersubscription Amounts subscribed for by all Right Holders, subject to
rounding by the Board of Directors to the extent it reasonably deems necessary.

          (e) In the event that Notices of Acceptance are not given by the Right
Holders in respect of all the New Securities, the Corporation shall have 90 days
from the expiration of the period set forth in paragraph (c) above to issue,
sell or exchange all or any part of such New Securities as to which a Notice of
Acceptance has not been given by the Right Holders (the "Refused Securities"),
but only to the offerees or purchasers and only upon terms and conditions
(including, without limitation, unit prices and interest rates) which are
described in the Offer.

          (f) In the event the Corporation shall propose to sell less than all
the Refused Securities (any such sale to be in the manner and on the terms
specified in paragraph (e) above), then each Right Holder may, at its sole
option and in its sole discretion, reduce the number or amount of the New
Securities specified in its Notice of Acceptance to an amount that shall be not
less than the number or amount of the New Securities that the Right Holder
elected to purchase pursuant to paragraph (d) above multiplied by a fraction,
(i) the numerator of which shall be the number or amount of New Securities the
Corporation actually proposes to issue, sell or exchange (including New
Securities to be issued or sold to Right Holders pursuant to paragraph (d) above
prior to such reduction) and (ii) the denominator of which shall be the amount
of all New Securities.  In the event that any Right Holder so elects to reduce
the number or amount of New Securities specified in its Notice of Acceptance,
the Corporation may not issue, sell or exchange more than the reduced number or
amount of the New Securities unless and until such securities have again been
offered to the Right Holders in accordance with paragraph (c) above.

          (g) Upon the closing of the issuance, sale or exchange of all or less
than all the Refused Securities, the Right Holders shall acquire from the
Corporation, and the

                                      -15-
<PAGE>

Corporation shall issue to the Right Holders, the number or amount of New
Securities specified in the Notices of Acceptance, as reduced pursuant to
paragraph (f) above if the Right Holders have so elected, upon the terms and
conditions specified in the Offer. The purchase by the Right Holders of any New
Securities is subject in all cases to the preparation, execution and delivery by
the Corporation and the Right Holders of a purchase agreement relating to such
New Securities reasonably satisfactory in form and substance to the Right
Holders and their respective counsel.

          (h) Any New Securities not acquired by the Right Holders or other
persons in accordance with paragraph (e) above may not be issued, sold or
exchanged until they are again offered to the Right Holders under the procedures
specified in this Agreement.

          (i) This right of first refusal shall run to each Investor, each
Series B Investor, each Founder and any of their respective permitted assignees
under paragraph (j) of this Section 8.1 only for so long as they hold the
following number of shares of Common Stock (including in such number shares of
Common Stock issuable upon conversion of Preferred Stock):

              (i)  in the case of the Founders and the Series B Investors who
were parties to the Stock Purchase Agreement dated May 26, 1994, and their
respective permitted assignees, 50,000 shares; and

              (ii) in the case of all other Series B Investors and the
Investors, and their respective permitted assignees, 200,000 shares (including
shares held by their respective Affiliates (as hereinafter defined)).

          (j) This right of first refusal may be assigned, in whole or in part,
(i) to any Affiliate (as hereinafter defined) of any Right Holder or (ii) to any
assignee who acquires not less than 50,000 shares of Common Stock in the case of
an assignment from assignor described in clause (i) of paragraph (i) of this
Section 8.1, or 200,000 shares of Common Stock in the case of an assignment from
an assignor described in clause (ii) of paragraph (i) of this Section 8.1 (in
each case, including in such number shares of Common Stock issuable upon
conversion of Preferred Stock and appropriately adjusted to take account of any
stock split, stock dividend, combination of shares, or the like).  As used in
this Section, an Affiliate of a Right Holder shall mean any partner of the Right
Holder that is a partnership or any person or entity that, directly or
indirectly, through one or more intermediaries, controls, or is controlled by,
or is under common control with, the Right Holder.

          (k) This Section 8.1 shall supersede and replace Section 8.1 of the
Series B Purchase Agreement, which Section 8.1 shall no longer have any force or
effect.  Without limiting the generality of the foregoing, the Right Holders
under Section 8.1 of the Series B Purchase Agreement hereby consent to the sale
of the Shares and the Warrants and waive their rights of first refusal under
Section 8.1 of the Series B Purchase Agreement (including their rights to notice
thereunder) in connection with the issuance and sale of the Shares and the
Warrants, the issuance of the Warrant Shares upon exercise of the Warrants, and
the issuance of the Reserved Shares upon conversion of the Shares and the
Warrant Shares.

however, that nothing in this Section shall prevent the Corporation from
- -------
discontinuing the lease or maintenance of any such facilities if such

material adverse effect on the Corporation.

          ----------------
be paid or discharged, before the same shall become delinquent, (1) all material

all dividends declared but unpaid on each share of the Series A Preferred Stock
to and including the date full payment shall be tendered to the holders of the
Series A Preferred Stock with respect to such liquidation, dissolution or
winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series A Preferred Stock of all amounts so
distributable to them, then the entire remaining assets of the Corporation
available for such distribution shall be distributed ratably

                                      -2-
<PAGE>

among the holders of the Series A Preferred Stock in proportion to the full
preferential amount each such holder is otherwise entitled to receive under this

them.

                  (iv)  Upon conversion of shares of Preferred Stock into shares
of Common Stock pursuant to Section 2 below, the holders of such Common Stock
shall not be entitled to any preferential payment or distribution in case of any
liquidation, dissolution or winding up, but shall share ratably in any
distribution of the assets of the Corporation to all the holders of Common
Stock.

                  (v)  The amounts payable with respect to shares of Preferred

referred to as the "Liquidation Payments".

             (b)  Distributions Other than Cash.  Whenever the distributions
                  -----------------------------
provided for in this Section 1 shall be payable in property other than cash, the

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

holders of capital stock of the Corporation immediately prior to such merger or
consolidation continue to hold at least eighty percent (80%) in voting power of
the capital stock of the surviving corporation, in which case the provisions of
Subsection 2(h) shall apply), or the sale of all or substantially all of the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the affairs of the Corporation for purposes of this Section 1 (i)
with respect to the Series C Preferred Stock, unless the holders of at least
two-thirds of the then outstanding shares of the Series C Preferred Stock elect
to the contrary, (ii) with respect to the Series B Preferred Stock, unless the
holders of at least eighty-five percent (85%) of the then outstanding shares of
the Series B Preferred Stock elect to the contrary, and (iii) with respect to
the Series A Preferred Stock, unless the holders of at least eighty percent
(80%) of the then outstanding shares of the Series A Preferred Stock elect to
the contrary, such election in each such case to be deemed made upon receipt of
notice thereof by the Corporation at least three days before the effective date
of such event. If such notice is given with respect to any series of Preferred
Stock, the provisions of Subsection 2(h) shall apply to such series of Preferred
Stock. Unless such election is made, any amounts received by the holders of the
Preferred Stock as a result of such merger or consolidation shall be deemed to
be applied toward, and all consideration received by the Corporation in such
asset sale together with all other available assets of the Corporation shall be

                                      -3-
<PAGE>

distributed toward, the Liquidation Payments attributable to such shares of
Preferred Stock in the order of preference set forth in Subsection 1(a).

(c)), stating a payment date, the amount of the Liquidation Payments and the
place where said Liquidation Payments shall be payable, shall be sent to the
holders of record of the Preferred Stock not less than twenty (20) days prior to
the payment date stated therein.  Any holder of outstanding shares of Preferred
Stock may waive any notice required by this Subsection by a written document
specifically indicating such waiver.

     Section 2.  Conversion.  The holders of Preferred Stock shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert; Conversion Price. Each share of Preferred 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 Preferred Stock, into such number of fully paid and nonassessable
shares of Common Stock as is determined in accordance with the following:

               (i)  in the case of the Series C Preferred Stock, by dividing
$3.15 by the Series C Conversion Price, determined as hereinafter provided, in
effect at the time of conversion. The Conversion Price at which shares of Common
Stock shall be deliverable upon conversion of the Series C Preferred Stock
without the payment of any additional consideration by the holder thereof (the
"Series C Conversion Price") shall initially be $3.15 per share of Common Stock.
Such initial Series C Conversion Price shall be subject to adjustment, in order
to adjust the number of shares of Common Stock into which the Series C Preferred
Stock is convertible, as hereinafter provided.

               (ii)  in the case of the Series B Preferred Stock, by dividing
$1.50 by the Series B Conversion Price, determined as hereinafter provided, in
effect at the time of conversion. The Conversion Price at which shares of Common
Stock shall be deliverable upon conversion of the Series B Preferred Stock
without the payment of any additional consideration by the holder thereof (the
"Series B Conversion Price") shall initially be $1.50 per share of Common Stock.
Such initial Series B Conversion Price shall be subject to adjustment, in order
to adjust the number of shares of Common Stock into which the Series B Preferred
Stock is convertible, as hereinafter provided.

               (iii)  in the case of the Series A Preferred Stock, by dividing
$0.50 by the Series A Conversion Price, determined as hereinafter provided, in
effect at the time of conversion. The Conversion Price at which shares of Common
Stock shall be deliverable upon conversion of the Series A Preferred Stock
without the payment of any additional consideration by the holder thereof (the
"Series A Conversion Price") shall initially be $0.50 per shares of Common
Stock. Such initial Series A Conversion Price shall be subject to adjustment, in
order

                                      -4-
<PAGE>

to adjust the number of shares of Common Stock into which the Series A Preferred
Stock is convertible, as hereinafter provided.

          (b)  Automatic Conversion.  Each share of Preferred Stock shall
               --------------------
automatically be converted into shares of Common Stock at the applicable
Conversion Price for its series then  in effect upon:

               (i)  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 at an offering price per share (prior
to underwriter commissions and discounts) of not less than (1) in the case of
the Series C Preferred Stock, $9.45, (2) in the case of the Series B Preferred
Stock, $4.50, and (3) in the case of the Series A Preferred Stock, $2.50 (in
each case as adjusted pursuant to Subsection 2(e)(vi) hereof to reflect any
stock dividends, distributions, combinations, reclassifications or other like
transactions effected by the Corporation in respect of its Common Stock) and
with gross proceeds to the Corporation of not less than (1) $20,000,000 in the
case of the Series C Preferred Stock and (2) $10,000,000 in the case of either
the Series B Preferred Stock or the Series A Preferred Stock (in the event of
which offering, the person(s) entitled to receive the Common Stock issuable upon
such conversion of the Preferred Stock shall not be deemed to have converted
that Preferred Stock until the closing of such offering); or

               (ii) (1) in the case of the Series C Preferred Stock, the written
election of the holders of not less than two-thirds, (2) in the case of the
Series B Preferred Stock, the written election of the holders of not less than
eighty-five percent (85 %), and (3) in the case of the Series A Preferred Stock,
the written election of the holders of not less than eighty percent (80%), of
the then outstanding shares of the applicable series of Preferred Stock to
require such mandatory conversion.

          (c)  Mechanics of Optional Conversions.  Before any holder of
               ---------------------------------
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, the holder shall surrender the certificate or certificates therefor at
the office of the Corporation or of any transfer agent for the Preferred Stock,
and shall send notice to the Corporation at such office that the holder elects
to convert the same and shall state therein the holder's name or the name or
names of the holder's nominees in which the holder wishes the certificate or
certificates for shares of Common Stock to be issued. On the date of conversion,
all rights with respect to the Preferred Stock so converted shall terminate,
except any of the rights of the holder thereof, upon surrender of the holder's
certificate or certificates therefor, to receive certificates for the number of
shares of Common Stock into which such Preferred Stock has been converted and
cash in an amount equal to all dividends declared but unpaid thereon and any and
all other amounts owing with respect thereto at such time. If so required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or by
the holder's attorney duly authorized in writing. No fractional share of Common
Stock shall be issued upon the optional conversion of Preferred Stock. In lieu
of any fractional share to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the applicable
Conversion Price then in effect. The Corporation shall, as soon as practicable
after

                                      -5-
<PAGE>

surrender of the certificate or certificates for conversion, issue and deliver
at such office to such holder of Preferred Stock, or to the holder's nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which the holder shall be entitled as aforesaid, together with cash in lieu
of any fraction of a share and cash in an amount equal to all dividends declared
but unpaid thereon and any and all other amounts owing with respect thereto at
such time. 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
Preferred 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.

          (d)  Mechanics of Automatic Conversions.  Upon the occurrence of an
               ----------------------------------
event specified in Subsection 2(b), the affected Series of Preferred Stock shall
be converted automatically without any further action by the holders of shares
thereof and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided, however, that
all holders of shares of Preferred Stock being converted shall be sent notice of
the occurrence of an event specified in Subsection 2(b) including the date such
event occurred (the "Automatic Conversion Date"), and the Corporation shall not
be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless certificates evidencing such shares of the
Preferred Stock being converted are either delivered to the Corporation or its
transfer agent, or the holder notifies the Corporation or any transfer agent
that such certificates have been lost, stolen, or destroyed and executes 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 bond.  On the Automatic Conversion Date, all
rights with respect to the Preferred Stock so converted shall terminate, except
any of the rights of the holder thereof, upon surrender of the holder's
certificate or certificates therefor, to receive certificates for the number of
share of Common Stock into which such Preferred Stock has been converted,
together with cash in an amount equal to all dividends declared but unpaid on,
and any and all other amounts owing with respect to, the shares of Preferred
Stock converted to and including the time of conversion.  Upon the automatic
conversion of the Preferred Stock, the holders of such Preferred Stock shall
surrender the certificates representing such shares at the office of the
Corporation or of its transfer agent.  If so required by the Corporation,
certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the
Corporation, duly executed by the registered holder or by the holder's attorney
duly authorized in writing.  Upon surrender of such certificates there shall be
issued and delivered to such holder, promptly at such office and in the 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
the Preferred Stock surrendered were convertible on the date on which such
automatic conversion occurred; together with cash in an amount equal to all
dividends declared but unpaid on, and any and all other amounts owing with
respect to, the shares of Preferred Stock converted to and including the time of
conversion.  No fractional share of Common Stock shall be issued upon the
automatic conversion of the Preferred Stock.  In lieu of any fractional share to
which the holder would otherwise be entitled, the Corporation shall pay cash
equal to such fraction multiplied by the applicable Conversion Price then in
effect.

series of Preferred Stock, the first date on which a share of such series of
Preferred Stock was issued.

                    (3)  "Convertible Securities" shall mean any evidences of
                          ----------------------
indebtedness, shares of capital stock (other than Common Stock) or other

                    (4)  "Additional Shares of Common Stock" shall mean all
                          ---------------------------------

Date;

                         (B)  up to 1,200,000 shares of Common Stock issued or

Subsection 2(e)(vi), no adjustment in the number of shares of Common Stock into
which a series of Preferred Stock is convertible shall be made, by adjustment in
the Conversion Price for such series of Preferred Stock in respect of the
issuance of Additional Shares of Common Stock, unless the consideration per
share for an Additional Share of Common Stock (determined pursuant to Subsection
2(e)(v)) issued or deemed to be issued by the Corporation is less than the
Conversion Price for such series of Preferred Stock in effect on the date of,
and immediately prior to, the issue of such Additional Share.

          (iii)  Issue of Securities Deemed Issue of Additional Shares of
                 --------------------------------------------------------
Common Stock.
- ------------

                 (1)  Options and Convertible Securities.  In the event the
                      ----------------------------------
Corporation at any time or from time to time after the applicable Original Issue
Date shall issue any Options or Convertible Securities or shall fix a record
date for the determination of holders

                                      -7-
<PAGE>

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 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 in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                         (A)  no further adjustment in the Conversion Price of
any series of Preferred Stock adjusted as a result of such deemed issuance 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;

                         (B)  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 of any series of Preferred Stock adjusted 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 readjusted to reflect such increase or decrease
insofar as it affects such Options or the rights of conversion or exchange under
such Convertible Securities;

                         (C)  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 of any series of Preferred Stock
adjusted 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 readjusted as if:

                              (I)  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

                              (II)  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

                                      -8-
<PAGE>

Subsection 2(e)(v)) upon the issue of the Convertible Securities with respect to
which such Options were actually exercised;

                         (D)  no readjustment pursuant to clause (B) or (C)
above shall have the effect of increasing the Conversion Price of any series of
Preferred Stock to an amount which exceeds the lower of (i) the Conversion Price
of such series of Preferred Stock immediately prior to the original adjustment
for such deemed issuance, or (ii) the Conversion Price of such series of
Preferred Stock that would have resulted from any issuance of Additional Shares
of Common Stock between the original adjustment for such deemed issuance and
such readjustment date;

                         (E)  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 of any series of Preferred Stock 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 (C) above; and

                         (F)  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 of any series of Preferred
Stock which became effective on such record date shall be cancelled as of the
close of business on such record date, and thereafter the Conversion Price of
such series of Preferred Stock shall be adjusted pursuant to this Subsection
2(e)(iii) as of the actual date of their issuance.

                    (2)  Stock Dividends, Stock Distributions and Subdivisions.
                         -----------------------------------------------------
In the event the Corporation at any time or from time to time after the
applicable 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:

                         (A)  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

                         (B)  in the case of any such subdivision, at the close
of business on the date immediately prior to the date upon which such corporate
action becomes effective.

If such record date she have been fixed and no part of such dividend shall been
paid on the date fixed therefor, the adjustment previously made in the
Conversion Price of any series of Preferred Stock which became effective on such
record date shall be cancelled as of the close of business; on such record date,
and thereafter the Conversion Price of such series of Preferred Stock shall be
adjusted pursuant to this Section 2(e)(iii) as of the time of actual payment of
such dividend.

          (iv) Adjustment of Conversion Price Upon Issuance of Additional Shares
               -----------------------------------------------------------------
of Common Stock.  In the event that at any time or from time to time after the
- ---------------
applicable Original Issue Date, the Corporation shall issue Additional Shares of
Common Stock (including, without limitation, Additional Shares of Common Stock
deemed to be issued pursuant to Subsection 2(e)(iii)(1) but excluding Additional
Shares of Common Stock deemed to be issued pursuant to Subsection 2(e)(iii)(2),
which event is dealt with in Subsection 2(e)(vi)(1)), without consideration or
for a consideration per share less than the Conversion Price of any series of
Preferred Stock in effect on the date of and immediately prior to such issue,
then and in such event, the Conversion Price of such series of Preferred Stock
shall be reduced, concurrently with such issue, to a price (calculated to the
nearest cent) determined in accordance with the following formula:


                             (P1) (Q1) + (P2) (Q2)
                    NCP =
                             _____________________
                                  Q1   +   Q2

     where:

          NCP       =         New Conversion Price of the affected series of
                              Preferred Stock.

          P(1)      =         Conversion Price for such series of Preferred
                              Stock in effect immediately prior to new issue.

          Q1        =         Number of shares of Common Stock outstanding, or
                              deemed to be outstanding as set forth below,
                              immediately prior to such issue.

          P2        =         Weighted average price per share received by the
                              Corporation upon such issue.

          Q2        =         Number of shares of Common Stock issued, or deemed
                              to have been issued, in the subject transaction.

provided that for the purpose of this Subsection 2(e)(iv), all shares of Common
- --------
Stock issuable upon exercise or conversion of any Options or Convertible
Securities outstanding immediately prior to such issue shall be deemed to be
outstanding, and immediately after any Additional Shares of Common Stock are
deemed issued pursuant to Subsection 2(e)(iii), such Additional Shares of Common
Stock shall be deemed to be outstanding; and provided further, that the
                                             -------- --------
applicable Conversion Price shall not be so reduced at any time if the amount of
such reduction would be an amount less than $.01, 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 $.0l or more.

          (v)  Determination of Consideration.  For purposes of this Subsection
               ------------------------------
2(e), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                                      -10-
<PAGE>

               (1)  Cash and Property:  Such consideration shall:
                    -----------------

                    (A)  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;

                    (B)  insofar as it consists of property other than cash, be
computed at the fair value thereof at the time of such issue, as determined in
good faith by the Board of Directors; and

                    (C)  in the event 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 (A) and (B) above, as
determined in good faith by the Board of Directors.

               (2)  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 Subsection 2(e)(iii)(1), relating to Options and
Convertible Securities, shall be determined by dividing (x) 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 (y)
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.
- ----------------------------------------------

               (1)  Stock Dividends, Distributions or Subdivisions. In the event
                    ----------------------------------------------
the Corporation shall be deemed to issue Additional Shares of Common Stock
pursuant to Subsection 2(e)(iii)(2) in a stock dividend, stock distribution or
subdivision, the Conversion Price of each series of Preferred Stock in effect
immediately before such deemed issuance shall, concurrently with the
effectiveness of such deemed issuance, be proportionately decreased.

               (2)  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 of each series of Preferred Stock in effect immediately
prior to such combination or consolidation shall,

                                     -11-
<PAGE>

concurrently with the effectiveness of such combination or consolidation, be
proportionately increased.

          (f)  Adjustments for Certain Dividends and Distributions.  In the
               ---------------------------------------------------
event that at any time or from time to time after the applicable Original Issue
Date the Corporation shall make or issue, or fix a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in securities of the Corporation other than shares of
Common Stock, then and in each such event provision shall be made so that the
holders of Preferred Stock shall receive upon conversion thereof in addition to
the number of shares of Common Stock receivable thereupon, the amount of
securities of the Corporation that they would have received had their Preferred
Stock been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event to and including the
conversion date, retained such securities receivable by them as aforesaid during
such period, giving application during such period to all adjustments called for
herein.

          (g)  Adjustment for Reclassification, Exchange, or Substitution.  In
               ----------------------------------------------------------
the event that at any time or from time to time after the applicable Original
Issue Date, the Common Stock issuable upon the conversion of Preferred Stock
shall be changed into the same or a different number of shares of any class or
classes of stock, whether by capital reorganization, reclassification, or
otherwise (other than a subdivision or combination of shares or stock dividend
provided for above, or a merger, consolidation, or sale of assets provided for
below), then and in each such event the holder of any share or shares of
Preferred Stock shall have the right thereafter to convert such shares into the
kind and amount of shares of stock and other securities and property receivable
upon such reorganization, reclassification, or other change, by the holder of a
number of shares of Common Stock equal to the number of shares of Common Stock
into which such shares of Preferred Stock might have been converted immediately
prior to such reorganization, reclassification, or change, all subject to
further adjustment as provided herein.

          (h)  Adjustment for Merger, Consolidation or Sale of Assets.  In the
               ------------------------------------------------------
event that at any time or from time to time after the applicable Original Issue
Date, the Corporation shall merge or consolidate with or into another entity or
sell all or substantially all of its assets, each share of Preferred Stock as to
which such consolidation, merger or sale is not treated as a liquidation under
Subsection l(c) shall thereafter be convertible into the kind and amount of
shares of stock or other securities or property to which a holder of the number
of shares of Common Stock of the Corporation deliverable upon conversion of such
Preferred Stock would have been entitled to receive upon such consolidation,
merger or sale; and, in such case, appropriate adjustment (as determined in good
faith by the Board of Directors) shall be made in the application of the
provisions set forth in this Section 2 with respect to the rights and interest
thereafter of the holders of Preferred Stock, to the end that the provisions set
forth in this Section 2 (including provisions with respect to changes in and
other adjustments of the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of Preferred Stock.

          (i)  No Impairment.  The Corporation shall not, by amendment of its
               -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation,

                                     -12-
<PAGE>

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 term 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 2
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 Preferred Stock against
impairment.

          (j)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price of any series of Preferred
Stock pursuant to this Section 2, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
furnish to each holder of such series of Preferred Stock 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 holder of any such series of Preferred Stock,
furnish or cause to be furnished to such holder a like certificate setting forth
(i) such adjustments and readjustments, (ii) the Conversion Price of such series
of Preferred Stock 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 the conversion of each share of such series of Preferred Stock.

          (k)  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 send notice to
each holder of Preferred Stock at least ten (10) days prior to such record date
specifying the date on which any such record is to be taken for the purpose of
such dividend or distribution.

          (l)  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 conversion of
the Preferred Stock.

          (m)  Certain Taxes.  The Corporation shall pay any issue or transfer
               -------------
taxes payable in connection with the conversion of Preferred 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
the Preferred Stock.

          (n)  Closing of Books.  The Corporation shall at no time close its
               ----------------
transfer books against the transfer of any Preferred Stock or of any shares of
Common Stock issued or issuable upon the conversion of any shares of Preferred
Stock in any manner which interferes with the timely conversion or transfer of
such Preferred Stock or Common Stock.

signed by such holder specifying the number of shares of Series B Preferred
Stock so to be redeemed (which number shall be not more than such holder's
Series B Pro Rate Redemption Amount), and (B) certificates for the shares of
Series B Preferred Stock so to be redeemed, together with stock powers therefor
duly executed by such holder in blank.

Corporation has funds legally available for such purpose, up to a number of
shares of Series C Preferred Stock equal to such holder's Series C Pro Rata
Redemption Amount (as hereinafter defined) at a redemption price of $3.15 per
share.  Such election may be made only by delivering to the Corporation within
thirty (30) days after the Series C Notice Date (A) a written election signed by
such holder specifying the number of shares of Series C Preferred Stock so to be
redeemed (which number shall be not more than such holder's Series C Pro Rata
Redemption Amount), and (B) certificates for the shares of Series C Preferred
Stock so to be redeemed, together with stock powers therefor duly executed by
such holder in blank.

          (iii)  For purposes of this Subsection 6(b), each holder of Series C
Preferred Stock's "Series C Pro Rata Redemption Amount" shall be the greatest
whole number represented by a fraction, the numerator or which is the product of
the number of shares of Series C Preferred Stock held by such holder times the
Series C Put Net Proceeds, and the denominator or which is the product of the
total number of shares of Series C Preferred Stock issued and outstanding times
$1.50.

          (iv) On the Series C Redemption Date the Corporation shall redeem from
the electing holders of Series C Preferred Stock the shares of Series C
Preferred Stock as to which election notices have been properly sent, to the
extent the Corporation has funds legally available for such purpose.

          (v) If the funds of the Corporation legally available for redemption
of shares of Series C Preferred Stock on the Series C Redemption Date are
insufficient to redeem the total number of shares of Series C Preferred Stock
submitted for redemption, those funds which are legally available will be used
to redeem the maximum possible number of whole shares ratably among the holders
of such shares in accordance with the manner of determining the Series C Pro
Rata Redemption Amount set forth above.  The shares of Series C Preferred Stock
not redeemed shall remain outstanding and entitled to all rights and preferences
provided herein.

          (c) Concurrent Redemption of Series B Preferred Stock and Series C
              --------------------------------------------------------------
Preferred Stock.  If the Corporation shall become obligated under this Section 6
- ---------------
to redeem shares of both Series B Preferred Stock and Series C Preferred Stock
at a time when the funds of the Corporation legally available for redemption of
such shares on the Series B Redemption Date and the Series C Redemption Date
would be insufficient to redeem the total number of shares of Series B Preferred
Stock and Series C Preferred Stock submitted for redemption, those funds which
are legally available will be used to redeem the maximum possible number of
whole shares of Series B Preferred Stock and Series C Preferred Stock ratably
among the holders of such shares in accordance with the manner of determining
their respective Series B Pro Rata Redemption Amount and Series C Pro Rata
Redemption Amount set forth above.  The shares of Series B Preferred Stock and
Series C Preferred Stock not redeemed shall remain outstanding and entitled to
all rights and preferences provided herein.

     ---------   ---------------
of the Corporation not expressly provided for to the contrary herein shall be
vested in the Common Stock.

          Section 8.  Notices.  All notices required or permitted to be sent
          ---------   -------
pursuant to this Article Fourth shall be deemed sufficient if contained in a
written instrument and delivered in person or duly sent by first-class mail
postage prepaid (other than in the case of notices to non-U.S. residents) or by
fax or DHL, Federal Express or other recognized express international courier
service, addressed to the intended recipient at the recipient's address as it

                             Void after May __, 2004


     Sequenom, Inc., a Delaware corporation (the "Corporation"), hereby
covenants and agrees with ____________ as follows:

1.  The Warrant.
    -----------

     1.01  For value received and subject to the terms and conditions
hereinafter set forth, the registered holder of this Warrant (the
"Warrantholder") is entitled upon its surrender, with the subscription form
annexed hereto duly executed, at the office of the Corporation at 11555 Sorrento
Valley Road, Suite C, San Diego, California 92121, or at such other office as
the Corporation shall notify the Warrantholder in writing, to purchase from the
Corporation __________ fully paid and non-assessable shares of the Series C
Convertible Preferred Stock, par value $.001 per share ("Series C Preferred
Stock"), of the Corporation for $3.15 per share (the "Exercise Price"), subject
to adjustment as set forth in Sections 2 and 4 hereof.  This Warrant may be
exercised in full or in part from time to time.  As promptly as practicable
after surrender of this Warrant and receipt of payment of the Exercise Price,
the Corporation shall issue and deliver to the Warrantholder a certificate or
certificates for shares of Series C Preferred
<PAGE>

Stock, in certificates of such denominations and in such name as the
Warrantholder may specify, together with any other stock, securities or property
that such holder may be entitled to receive pursuant hereto. This Warrant shall
expire at the close of business on May 8, 2004, and shall be void thereafter.
Upon and after the Automatic Conversion Effective Time (as defined in Section
4), the right to purchase Series C Preferred Stock granted herein shall
terminate, and this Warrant shall represent the right to purchase shares of the
Common Stock, par value $.001 per share, of the Corporation ("Common Stock") as
provided in Section 4 hereof. The shares of Series C Preferred Stock, Common
Stock or securities or other property purchasable upon exercise of this Warrant
are sometimes referred to hereinafter as "Warrant Shares".

     1.02  Prior to the Automatic Conversion Effective Time (as defined in
Section 4), the Corporation shall at all times have authorized and reserved for
purposes of issue upon exercise of the rights evidenced hereby, a sufficient
number of shares of its Series C Preferred Stock to provide for the exercise of
such rights, and shall at all times have authorized and reserved a sufficient
number of shares of its Common Stock for purposes of issue upon conversion of
such shares of Series C Preferred Stock under the terms of the Charter (as
defined in Subsection 2.05). From and after the Automatic Conversion Effective
Time, the Corporation shall at all times have authorized and reserved for
purposes of issue upon exercise of the rights evidenced hereby, a sufficient
number of shares of its Common Stock to provide for the exercise of such rights.
Upon surrender for exercise, this Warrant shall be cancelled and shall not be
reissued; provided, however, that upon the partial exercise hereof a substitute
Warrant of like tenor and date to the original Warrant representing the rights
to subscribe for and purchase any such unexercised portion hereof shall be
issued.

     1.03  This Warrant may be subdivided into one or more stock purchase
warrants entitling the Warrantholder to purchase Warrant Shares in multiples of
one or more whole shares, upon surrender of the Warrant by the Warrantholder for
such purpose at the office of the Corporation.

     1.04  The Corporation shall maintain at its office (or at such other office
or agency of the Corporation as it may from time to time designate in writing to
the Warrantholder), a register containing the names and address of the holder of
this Warrant.  The registered holder of this Warrant shall be the person in
whose name this Warrant is originally issued and registered, unless a subsequent
holder shall have presented to the Corporation the Warrant, duly assigned to
him, for inspection, and a written notice of his acquisition of the Warrant and
designating in writing the address of such holder, in which case such subsequent
holder of the Warrant shall become a subsequent registered holder, and a
Warrantholder as defined herein.  Any Warrantholder may change his address as
shown on such register by written notice to the Corporation requesting such
change.  Any written notice required or permitted to be given to any
Warrantholder shall be delivered in person or duly sent by first class mail
postage prepaid (other than to non-U.S. parties) or fax or DHL, Federal Express
or other internationally recognized express courier service, to such
Warrantholder at his address as shown on such register.

     1.05  If any shares of Common Stock issuable hereunder upon and after the
Corporation's initial public offering of Common Stock require listing on any
domestic securities exchange, before such shares may be issued upon exercise of
this Warrant, the Corporation shall,

                                      -2-
<PAGE>

at its expense and as expeditiously as possible, use its best efforts to cause
such shares to be duly approved for listing on such domestic securities
exchange.

2.  Adjustment Rights.
    -----------------

     The Exercise Price and the number of Warrant Shares purchasable hereunder
are subject to adjustment, as follows:

     2.01  If the Corporation shall effect a subdivision or combination or
consolidation of shares (whether by way of stock split, reverse stock split or
otherwise) or other capital reorganization or reclassification of any class or
series of the capital stock of the Corporation for which this Warrant is then
exercisable, or the payment of a stock dividend or other distribution of stock
with respect to any such class or series of capital stock, then the number of
Warrant Shares purchasable hereunder and the Exercise Price shall be
appropriately adjusted in such a manner as to entitle the Warrantholder to
receive upon exercise of this Warrant, for the same aggregate consideration, the
same total number, type, class and series of securities and other property as
such Warrantholder would have received as a result of the event requiring the
adjustment had such Warrantholder exercised this Warrant in full immediately
prior to such event.

     2.02  If there shall occur any consolidation or merger of the Corporation
or sale of all or substantially all of the Corporation's assets, then as a
condition of such consolidation, merger or sale, lawful and adequate provision
shall be made whereby the Warrantholder shall thereafter have the right to
purchase and receive upon the basis and upon the terms and conditions herein
specified and in lieu of the Warrant Shares immediately theretofore purchasable
and receivable upon exercise of this Warrant, such securities and other property
as such Warrantholder would have received as a result of the event requiring the
adjustment had such Warrantholder exercised this Warrant in full immediately
prior to such event, and in any such case appropriate provision shall be made
with respect to the rights and interests of the Warrantholder to the end that
the provisions hereof shall thereafter be applicable, as nearly as may be, in
relation to the securities and other property thereafter deliverable upon the
exercise hereof.

     2.03  Upon the occurrence of any event specified in Subsection 2.01 or
Subsection 2.02, then, and in each such case, the Corporation shall give written
notice thereof to the Warrantholder in accordance with Subsection 1.04, which
notice shall state the adjustment in the Warrant Shares and the Exercise Price
resulting from such event, and shall set forth in reasonable detail the method
of calculation and the facts upon which such calculation is based.

     2.04  In case at any time: (1) the Corporation shall pay any dividend or
make any distribution (other than regular cash dividends from earnings or earned
surplus paid at an established rate) to the holders of its Series C Preferred
Stock or Common Stock or offer to all holders of its Series C Preferred Stock or
Common Stock the right to subscribe for the purchase of any shares of capital
stock or securities convertible into or exercisable for such shares of capital
stock; (2) there shall be any capital reorganization or reclassification of the
capital stock of the Corporation, or consolidation or merger of the Corporation,
or sale of all or substantially all of its assets; or (3) there shall be a
voluntary or involuntary dissolution, liquidation or

                                      -3-
<PAGE>

winding-up of the Corporation; then, in any one or more of such cases, the
Corporation shall give written notice thereof to the Warrantholder in accordance
with Subsection 1.04, which notice shall state the date on which (a) the books
of the Corporation shall close or a record date shall be fixed for determining
the stockholders entitled to such dividend, distribution or subscription rights,
or (b) such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding-up shall take place, as the case may be.
Such notice shall also provide reasonable details of the proposed transaction
and specify the date as of which the record holders of Series C Preferred Stock
or Common Stock shall participate in such dividend, distribution or subscription
rights, or shall be entitled to exchange their Series C Preferred Stock or
Common Stock for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up, as the case may be. Such written notice shall be
given at least fifteen (15) days prior to the action in question and not less
than fifteen (15) days prior to the record date or the date on which the
Corporation's transfer books are closed in respect thereto.

     2.05  Antidilution rights applicable to the Series C Preferred Stock
purchasable hereunder are set forth in the Corporation's Certificate of
Incorporation, as amended through the date hereof, a true and complete copy of
which has been furnished to Warrantholder (the "Charter").  The Corporation
shall promptly provide the Warrantholder with any restatement, amendment,
modification or waiver of the Charter and with any Certificate of Adjustment
sent to the holders of Series C Preferred Stock in accordance with the Charter
relating to any adjustment or readjustment of the Conversion Price of the Series
C Preferred Stock.

3.  Payment of Exercise Price.  The Exercise Price may be paid at the
    -------------------------
Warrantholder's election either (i) by cash, certified or official bank check,
or wire transfer of funds to an account designated by the Corporation, or (ii)
by surrender of Warrants ("Net Issuance") as determined below.  If the
Warrantholder elects the Net Issuance method, the Corporation shall issue Series
C Preferred Stock or Common Stock as follows:

     (A) Prior to the Automatic Conversion Effective Time (as defined in Section
4), the Corporation shall issue Series C Preferred Stock in accordance with the
following formula:

<TABLE>
<S>              <C>     <C>

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

     Where:      X   =   the number of shares of Series C Preferred Stock to be issued to the Warrantholder

                 Y   =   the number of shares of Series C Preferred Stock requested to be exercised under this Warrant

                 A   =   the current fair market value of one (1) share of Series C Preferred Stock

                 B   =   the Exercise Price
</TABLE>

                                      -4-
<PAGE>

     As used herein, the current fair market value of a share of Series C
Preferred Stock shall mean the price per share which the Corporation could
obtain from a willing buyer for shares of Series C Preferred Stock, as
determined in good faith by the Corporation's Board of Directors, unless the
Corporation shall become subject to a merger, acquisition or other consolidation
pursuant to which the holders of Series C Preferred Stock receive securities
and/or other property in exchange for their Series C Preferred Stock, in which
case the fair market value of Series C Preferred Stock shall be deemed to be the
value of the securities and other property received by the holders of the
Corporation's Series C Preferred Stock per share of Series C Preferred Stock
pursuant to such merger, acquisition or other consolidation.

     (B) Upon and after the Automatic Conversion Effective Time, the Corporation
shall issue Common Stock in accordance with the following formula:

<TABLE>
<S>              <C>     <C>
                 X   =   (Y)(A-B)/A

     Where:      X   =   the number of shares of Common Stock to be issued to the Warrantholder

                 Y   =   the number of shares of Common Stock requested to be exercised under this Warrant

                 A   =   the fair market value of one (1) share of Common Stock

                 B   =   the Exercise Price
</TABLE>

     As issued herein, current fair market value of Common Stock shall mean with
respect to each share of Common Stock:

          (i) if the exercise is in connection with the Corporation's initial
     public offering of Common Stock, and if the Corporation's Registration
     Statement relating to such public offering has been declared effective by
     the SEC, then the initial "Price to Public" specified in the final
     prospectus with respect to the offering;

          (ii) if this Warrant is exercised after, and not in connection with,
     the Corporation's initial public offering of Common Stock and

               (a) if the Common Stock is traded on a national securities
          exchange or quoted on the Nasdaq Stock Market, the fair market value
          shall be deemed to be the average of the closing prices over a twenty-
          one (21) day period ending three days before the day the current fair
          market value of the Common Stock is being determined; or

               (b) if the Common Stock is not listed on a national securities
          exchange or quoted on the Nasdaq Stock Market but is actively traded
          over-the-counter, the fair market value shall be deemed to be the
          average of the closing bid and asked prices reported by the National
          Quotation Bureau (or similar system) over the

                                      -5-
<PAGE>

          twenty-one (21) day period ending three days before the day the
          current fair market value of the Common Stock is being determined;

          (iii)  if at any time the Common Stock is not listed on any national
     securities exchange or quoted on the Nasdaq Stock Market or actively traded
     or in the over-the-counter market, the current fair market value of Common
     Stock shall be the price per share which the Corporation could obtain from
     a willing buyer (not a current employee or director) for shares of Common
     Stock sold by the Corporation, from authorized but unissued shares, as
     determined in good faith by its Board of Directors, unless the Corporation
     shall become subject to a merger, acquisition or other consolidation
     pursuant to which the holders of Common Stock receive securities and/or
     other property in exchange for their Common Stock, in which case the fair
     market value of Common Stock shall be deemed to be the value of the
     securities and other property received by the holders of the Corporation's
     Common Stock per share of Common Stock pursuant to such merger, acquisition
     or other consolidation.

     Upon partial exercise of this Warrant, the Corporation shall promptly issue
an amended Warrant representing the remaining number of shares purchasable
hereunder.  All other terms and conditions of such amended Warrant shall be
identical to those contained herein, including, but not limited to the Effective
Date hereof.

4.   Automatic Conversion of Series C Preferred Stock.  If at any time the
     ------------------------------------------------
issued and outstanding shares of the Corporation's Series C Preferred Stock
shall be automatically converted into shares of Common Stock under the terms of
the Charter, then upon and after the effective time of such automatic conversion
of the Series C Preferred Stock (the "Automatic Conversion Effective Time"), the
right to purchase Series C Preferred Stock granted herein shall terminate, and
this Warrant shall represent the right to purchase a number of shares of Common
Stock calculated as follows:

<TABLE>
<S>              <C>     <C>
                 X   =   (Y)(Z)

     where:      X   =   the number of shares of Common Stock purchasable under this Warrant upon and after such
                         Automatic Conversion Effective Time

                 Y   =   the number of shares of Series C Preferred Stock purchasable under this Warrant
                         immediately prior to such Automatic Conversion Effective Time

                 Z   =   the number of shares of Common Stock issuable upon conversion of each share of Series C
                         Preferred Stock immediately prior to such Automatic Conversion Effective Time

</TABLE>

          and the Exercise Price per share of Common Stock shall be a price
          calculated as follows:

                           -6-
<PAGE>

<TABLE>
<S>              <C>     <C>
                 A   =   (B) (X) /Y

     where:      A   =   the Exercise Price per share of Common Stock upon and after such Automatic Conversion
                         Effective Time

                 B   =   the Exercise Price per share of Series C Preferred Stock immediately prior to such
                         Automatic Conversion Effective Time

                 X   =   the number of shares of Series C Preferred Stock purchasable under this Warrant
                         immediately prior to such Automatic Conversion Effective Time

                 Y   =   the number of shares of Common Stock purchasable under this Warrant upon and after such
                         Automatic Conversion Effective Time
</TABLE>

     Thereafter, the number of shares of Common Stock purchasable hereunder and
the Exercise Price per share shall be subject to adjustment for the types of
events described in Section 2 above that occur with respect to the Common Stock.

5.   Restrictions.  The Warrant Shares issuable u upon exercise of this Warrant
     ------------
are subject to the terms and provisions of a Voting Agreement among the

                                   ---------

FOURTH:  The total number of shares of all classes of stock which the
- ------
Corporation has authority to issue is 4,399,000 shares, consisting of 2,301,000
shares of Common Stock, par value $.001 per share (the "Common Stock"), and
2,098,000 shares of Series A Convertible Preferred Stock, par value $.001 per
share (the "Series A Preferred Stock"), amounting to an aggregate par value of
$4,399.

     The powers, preferences and rights, and the qualifications, limitations or
restrictions thereof, in respect of each class or series of stock of the
Corporation shall be as follows:

     Section 1.  Liquidation Rights.
     ---------   ------------------

          (a) Treatment at Liquidation, Dissolution or Winding Up.  In the event
              ---------------------------------------------------
of any liquidation, dissolution or winding up of the affairs of the Corporation,
whether voluntary or involuntary, the holders of each share of the Series A
Preferred Stock shall be entitled to be paid first out of the assets of the
Corporation available for distribution to holders of the Corporation's capital
stock of all classes an amount equal to the greater of:

               (i) $0.50 per share of Series A Preferred Stock (which amount
     shall be subject to equitable adjustment whenever there shall occur a stock
     dividend, stock split, combination of shares, reclassification or other
     similar event with respect to the Series A Preferred Stock) plus all
     dividends declared but unpaid thereon, to and including the date full
     payment shall be tendered to the holders of the Series A Preferred Stock
     with respect to such liquidation, .dissolution or winding up, or

               (ii) such amount per share of Series A Preferred Stock as would
     have been payable had all shares of Series A Preferred Stock been converted
     to Common Stock immediately prior to such event of liquidation, dissolution
     or winding up pursuant to the provisions of Section 2 hereof, plus all
     dividends declared but unpaid on each share of Series A Preferred Stock to
     and including the date full payment shall be tendered to the holders of the
     Series A Preferred Stock with respect to such liquidation, dissolution or
     winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series A Preferred Stock of all amounts
distributable to them under this Subsection 1(a), then the entire assets of the
Corporation available for such distribution shall be distributed ratably among
the holders of the Series A Preferred Stock in proportion to the full
preferential amount each such holder is otherwise entitled to receive.

     After such payments shall have been made in full to the holders of the
Series A Preferred Stock or funds necessary for such payments shall have been
set aside by the Corporation in trust for the account of holders of Series A
Preferred Stock so as to be available for such payments, the remaining assets
available for distribution shall be distributed among the holders of the Common
Stock ratably in proportion to the number of shares of Common Stock held by
them.
<PAGE>

     Upon conversion of shares of Series A Preferred Stock into shares of Common
Stock pursuant to Section 2 below, the holder of such Common Stock shall not be
entitled to any preferential payment or distribution in case of any liquidation,
dissolution or winding up, but shall share ratably in any distribution of the
assets of the Corporation to all the holders of Common Stock.

     The amounts payable with respect to shares of Series A Preferred Stock
under this Section 1 are sometimes hereinafter referred to as "Liquidation
Payments."

          (b) Distributions Other than Cash.  Whenever the distribution provided
              -----------------------------
for in this Section 1 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.

          (c) Merger as Liquidation, etc.  The merger or consolidation of the
              --------------------------
Corporation into or with another corporation (except one in which the holders of
capital stock of the Corporation immediately prior to such merger or
consolidation continue to hold at least eighty percent (80%) in voting power of
the capital stock of the surviving corporation, in which case the provisions of
Subsection 2(h) shall apply), or the sale of all or substantially all of the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the affairs of the Corporation for purposes of this Section 1
unless the holders of at least eighty percent (80%) of the then outstanding
shares of Series A Preferred Stock elect to the contrary by giving written
notice thereof to the Corporation at least three days before the effective date
of such event.  If such notice is given, the provisions of Subsection 2(h) shall
apply.  Any amounts received by the holders of Series A Preferred Stock as a
result of such merger or consolidation shall be deemed to be applied toward, and
all consideration received by the Corporation in such asset sale together with
all other available assets of the Corporation shall be distributed toward, the
Liquidation Payments attributable to such shares of Series A Preferred Stock
unless such election is made

          (d) Notice.  Written notice of any proposed liquidation, dissolution
              ------
or winding up of the affairs of the Corporation (including any merger,
consolidation or sale of assets which may be deemed to be a liquidation,
dissolution or winding up of the affairs of the Corporation under Subsection
l(c)), stating a payment date, the amount of the Liquidation Payments and the
place where said Liquidation Payments shall be payable, shall be given by first
class mail, postage prepaid, or by telex to non-U.S. residents, not less than
twenty (20) days prior to the payment date stated therein, to the holders of
record of Series A Preferred Stock, such notice to be addressed to each such
holder at its address as shown by the records of the Corporation.

     Section 2.  Conversion.  The holders of the Series A Preferred Stock shall
     ---------   ----------
have conversion rights as follows (the "Conversion Rights"):

          (a) Right to Convert; Conversion Price.  Each share of Series A
              ----------------------------------
Preferred 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 A Preferred Stock, into such
number of fully paid and nonassessable shares of Common Stock as is determined
by

                                      -2-
<PAGE>

dividing $0.50 by the Conversion Price, determined as hereinafter provided,
in effect at the time of conversion.  The Conversion Price at which shares of
Common Stock shall be deliverable upon conversion without the payment of any
additional consideration by the holder of Series A Preferred Stock (the
"Conversion Price") shall initially be $0.50 per share of Common Stock.  Such
initial Conversion Price shall be subject to adjustment, in order to adjust the
number of shares of Common Stock into which the Series A Preferred Stock is
convertible, as hereinafter provided.

          (b) Automatic Conversion.  Each share of Series A Preferred Stock
              --------------------
shall automatically be converted into shares of Common Stock at the then
effective Conversion Price upon:

               (i) 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 at an initial public offering
     price per share not less than $2.50 (as adjusted pursuant to Subsection
     2(e)(vi) hereof to reflect any stock dividends, distributions,
     combinations, reclassifications or other like transactions effected by the
     Corporation in respect of its Common Stock) and with gross proceeds to the
     Corporation of not less than $10,000,000 (in the event of which offering,
     the person(s) entitled to receive the Common Stock issuable upon such
     conversion of the Series A Preferred Stock shall not be deemed to have
     converted that Series A Preferred Stock until the closing of such
     offering); or

               (ii) the written election of the holders of not less than eighty
     percent (80%) of the then outstanding shares of Series A Preferred Stock to
     require such mandatory conversion.

          (c) Mechanics of Mandatory Conversions.  Upon the occurrence of an
              ----------------------------------
event specified in Subsection 2(b), the Series A Preferred Stock shall be
converted automatically without any further action by the holders of such shares
and whether or not the certificates representing such shares are surrendered to
the Corporation or its transfer agent; provided, however, that all holders of
shares of Series A Preferred Stock shall be given written notice of the
occurrence of an event specified in Subsection 2(b) including the date such
event occurred (the "Mandatory Conversion Date"), and the Corporation shall not
be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless certificates evidencing such shares of the
Series A Preferred Stock being converted are either delivered to the corporation
or its transfer agent, or the holder notifies the Corporation or any transfer
agent that such certificates have been lost, stolen, or destroyed and executes
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 bond.  On the Mandatory Conversion
Date, all rights with respect to the Series A Preferred Stock so converted shall
terminate, except any of the rights of the holder thereof, upon surrender of the
holder's certificate or certificates therefor, to receive certificates for the
number of shares of Common Stock into which such Series A Preferred Stock has
been converted, together with cash in an amount equal to all dividends declared
but unpaid on, and any and all other amounts owing with respect to, the shares
of Series A Preferred Stock converted to and including the time of

                                      -3-
<PAGE>

conversion. Upon the automatic conversion of the Series A Preferred Stock, the
holders of such Series A Preferred Stock shall surrender the certificates
representing such shares at the office of the Corporation or of its transfer
agent. If so required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by written instrument, or
instruments of transfer, in form satisfactory to the Corporation, duly executed
by the registered holder or by the holder's attorney duly authorized in writing.
Upon surrender of such certificates there shall be issued and delivered to such
holder, promptly at such office and in the 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 the Series A Preferred
Stock surrendered were convertible on the date on which such automatic
conversion occurred, together with cash in an amount equal to all dividends
declared but unpaid on, and any and all other amounts owing with respect to, the
shares of Series A Preferred Stock converted to and including the time of
conversion. No fractional share of Common Stock shall be issued upon the
mandatory conversion of the Series A Preferred Stock. In lieu of any fractional
share 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) Mechanics of Optional Conversions.  Before any holder of Series A
              ---------------------------------
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, the holder shall surrender the certificate or certificates therefor at
the office of the Corporation or of any transfer agent for the Series A
Preferred Stock, and shall give written notice to the Corporation at such office
that the holder elects to convert the same and shall state therein the holder's
name or the name or names of the holder's nominees in which the holder wishes
the certificate or certificates for shares of Common Stock to be issued.  On the
date of conversion, all rights with respect to the Series A Preferred Stock so
converted shall terminate, except any of the rights of the holder thereof, upon
surrender of the holder's certificate or certificates therefor, to receive
certificates for the number of shares of Common Stock into which such Series A
Preferred Stock has been converted and cash in an amount equal to all dividends
declared but unpaid thereon and any and all other amounts owing with respect
thereto at such time.  If so required by the Corporation, certificates
surrendered for conversion shall be endorsed or accompanied by written
instrument or instruments of transfer, in form satisfactory to the Corporation,
duly executed by the registered holder or by the holder's attorney duly
authorized in writing.  No fractional share of Common Stock shall be issued upon
the optional conversion of the Series A Preferred Stock.  In lieu of any
fractional share 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 after
surrender of the certificate or certificates for conversion, issue and deliver
at such office to such holder of Series A Preferred Stock, or to the holder's

Common Stock to which the holder shall be entitled as aforesaid, together with
cash in lieu of any fraction of a share and cash in an amount equal to all

                        ----------------------------------
          Corporation at any time or from time to time after the Original Issue
          Date shall issue any Options or Convertible Securities or shall fix a
          record date for the 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 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 in any such case in
          which Additional Shares of Common Stock are deemed to be issued:

                         (A) 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;

                         (B) 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;

                         (C) 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

                    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

                              (II) 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 Subsection 2(e)(v)) upon the issue of the
                    Convertible Securities with respect to which such Options
                    were actually exercised;

                         (D) no readjustment pursuant to clause (B) or (C) above
               shall have the effect of increasing the Conversion Price to an
               amount which exceeds the lower of (i) the Conversion Price on the
               original adjustment date, or (ii) 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;

                         (E) 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
               (C) above; and

                         (F) 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
               cancelled as of the close of business on such record date, and
               thereafter the Conversion Price shall be adjusted pursuant to
               this Subsection 2(e)(iii) as of the actual date of their
               issuance.

                    (2) 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

                                      -7-

          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:

                         (A) 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

                         (B) in the case of any such subdivision, at the close
               of business on the date immediately prior to the date upon which
               such 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 in the Conversion Price which became
          effective on such record date shall be cancelled as of the close of
          business on such record date, and thereafter the Conversion Price
          shall be adjusted pursuant to this Section 2(e)(iii) as of the time of
          actual payment of such dividend.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
                    ----------------------------------------------------------
     Shares of Common Stock.  In the event that at any time or from time to time
     ----------------------
     after the Original Issue Date, the Corporation shall issue Additional
     Shares of Common Stock (including, without limitation, Additional Shares of
     Common Stock deemed to be issued pursuant to Subsection 2(e)(iii)(1) but
     excluding Additional Shares of Common Stock deemed to be issued pursuant to
     Subsection 2(e)(iii)(2), which event is dealt with in Subsection
     2(e)(vi)(1)), 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, to a price
     (calculated to the nearest cent) determined in accordance with the
     following formula:

                       (P1) (Ql) + (P2) (Q2)
               NPC =  ______________________
                          Q1     +     Q2
     where:

          NPC =   New Conversion Price.

          P1 =    Conversion Price of Series A Preferred Stock in effect
                  immediately prior to new issue.

          Q1 =    Number of shares of Common Stock outstanding, or deemed to be
                  outstanding as set forth below, immediately prior to such
                  issue.

          P2      Weighted average price per share received by the Corporation
                  upon such issue.

          Q2      Number of shares of Common Stock issued, or deemed to have
                  been issued, in the subject transaction.

     provided that for the purpose of this Subsection 2(e)(iv), all shares of
     -------------
     Common Stock issuable upon exercise or conversion of any Options or
     Convertible Securities outstanding immediately prior to such issue shall be
     deemed to be outstanding, and immediately after any Additional Shares of
     Common Stock are deemed issued pursuant to Subsection 2(e)(iii), such
     Additional Shares of Common Stock shall be deemed to be outstanding; and
     provided further, that the applicable Conversion Price shall not be so
     ----------------
     reduced at any time if the amount of such reduction would be an amount less
     than $.0l, 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 $.0l or more.

               (v) Determination of Consideration.  For purposes of this
                   ------------------------------
     Subsection 2(e), the consideration received by the Corporation for the
     issue of any Additional Shares of Common Stock shall be computed as
     follows:

                    (1) Cash and Property: Such consideration shall:
                             -----------------

                         (A) 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;

                         (B) insofar as it consists of property other than cash,
               be computed at the fair value thereof at the time of such issue,
               as determined in good faith by the Board of Directors; and

                         (C) in the event 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 (A) and (B) above, as determined in good
               faith by the Board of Directors.

                    (2) 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 Subsection 2(e)(iii)(1),
          relating to Options and Convertible Securities, shall be determined by
          dividing (x) 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

                                      -9-
<PAGE>

          Convertible Securities, by (y) 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.
     ----------------------------------------------

                    (1) Stock Dividends, Distributions or Subdivisions.  In the
                        ----------------------------------------------
          event the Corporation shall be deemed to issue Additional Shares of
          Common Stock pursuant to Subsection 2(e)(iii)(2) in a stock dividend,
          stock distribution or subdivision, the Conversion Price in effect
          immediately before such deemed issuance shall, concurrently with the
          effectiveness of such deemed issuance, be proportionately decreased.

                    (2) 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.

          (f) Adjustments for Certain Dividends and Distributions.  In the event
              ---------------------------------------------------
that at any time or from time to time after the original Issue Date the
Corporation shall make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive, a dividend or other distribution
payable in securities of the Corporation other than shares of Common Stock, then
and in each such event provision shall be made so that the holders of Series A
Preferred Stock shall receive upon conversion thereof in addition to the number
of shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had their Series A Preferred Stock
been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event to and including the
conversion date, retained such securities receivable by them as aforesaid during
such period, giving application during such period to all adjustments called for
herein.

          (g) Adjustment for Reclassification, Exchange, or Substitution.  In
              ----------------------------------------------------------
the event that at any time or from time to time after the Original Issue Date,
the Common Stock issuable upon the conversion of the Series A Preferred Stock
shall be changed into the same or a different number of shares of any class or
classes of stock, whether by capital reorganization, reclassification, or
otherwise (other than a subdivision or combination of shares or stock dividend
provided for above, or a merger, consolidation, or sale of assets provided for
below), then and in each such event the holder of each such share of Series A
Preferred Stock shall have the right thereafter to convert such share into the
kind and amount of shares of stock and other securities and property receivable
upon such reorganization, reclassification, or other change, by holders of the
number of shares of Common Stock into which such shares of Series A Preferred
Stock might have been converted immediately prior to such reorganization,
reclassification, or change, all subject to further adjustment as provided
herein.

                                     -10-
<PAGE>

          (h) Adjustment for Merger, Consolidation or Sale of Assets.  In the
              ------------------------------------------------------
event that at any time or from time to time after the Original Issue Date, the
Corporation shall merge or consolidate with or into another entity or sell all
or substantially all of its assets (other than a consolidation, merger or sale
which is treated as a liquidation pursuant to Subsection 1(c)), each share of
Series A Preferred Stock shall thereafter be convertible into the kind and
amount of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such Series A Preferred Stock would have been entitled upon such
consolidation, merger or sale; and, in such case, appropriate adjustment (as
determined in good faith by the Board of Directors) shall be made in the
application of the provisions set forth in this Section 2 with respect to the
rights and interest thereafter of the holders of Series A Preferred Stock, to
the end that the provisions set forth in this Section 2 (including provisions
with respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Series A Preferred Stock.

          (i) 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 2 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 the
Series A Preferred Stock against impairment.

          (j) Certificate as to Adjustments.  Upon the occurrence of each

     Section 1.  Liquidation Rights.
     ---------   ------------------

          (a)  In the event of any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary, the holders of
each share of the Series B Preferred Stock shall be entitled to be paid first
out of the assets of the Corporation available for distribution to holders of
the Corporation's capital stock of all classes an amount equal to the greater
of:

               (i)   $1.50 per share of series B Preferred Stock (which amount
     shall be subject to equitable adjustment whenever there shall occur a stock
     dividend, stock split, combination of shares, reclassification or other
     similar event with respect to the Series B Preferred Stock) plus all
     dividends declared but unpaid thereon, to and including the date full
     payment shall be tendered to the holders of the Series B Preferred Stock
     with respect to such liquidation, dissolution or winding up, or

               (ii)  such amount per share of Series B Preferred Stock as would
     have been payable had all shares of Series B Preferred Stock been converted
     to Common Stock immediately prior to such event of liquidation, dissolution
     or winding up pursuant to the provisions of Section 2 hereof, plus all
     dividends declared but unpaid on each shares of Series B Preferred Stock to
     and including the date full payment shall be tendered to the holders of the
     Series B Preferred Stock with respect to such liquidation, dissolution or
     winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series B Preferred Stock of all amounts so
distributable to them, then the entire assets of the Corporation available for
such distribution shall be distributed ratably among the holders of the Series B
Preferred Stock in proportion to the full preferential amount each such holder
is otherwise entitled to receive.

     After such payments shall have been made in full to the holders of the
Series B Preferred Stock or funds necessary for such payments shall have been
set aside by the Corporation in trust for the account of holders of Series B
Preferred Stock so as to be available for such payments, the holders of each

Corporation's capital stock of all classes an amount equal to the greater of:

               (i)   $0.50 per share of Series A Preferred Stock (which amount
     shall be subject to equitable adjustment whenever there shall occur a stock
     dividend, stock split, combination of shares, reclassification or other
     similar event with respect to the Series A Preferred Stock) plus all
     dividends declared but unpaid thereon, to and including the date full
     payment shall be tendered to the holders of the Series A Preferred Stock
     with respect to such liquidation, dissolution or winding up, or

               (ii)  such amount par share of Series A Preferred Stock as would
     have been payable had all shares of Series A Preferred Stock been converted
     to Common Stock immediately prior to such event of liquidation, dissolution
     or winding up pursuant to the provisions of Section 2 hereof, plus all
     dividends declared but unpaid on each share of Series A Preferred Stock to
     and including the date full payment shall be tendered to the holders of the
     Series A Preferred Stock with respect to such liquidation, dissolution or
     winding up.

     If the assets of the Corporation shall be insufficient to permit the
payment in full to the holders of the Series A Preferred Stock of all amounts so
distributable to them, then the entire remaining assets of the Corporation
available for such distribution shall be distributed ratably among the holders
of the Series A Preferred Stock in proportion to the full preferential amount
each such holder is otherwise entitled to receive.

     After such payments shall have been made in full to the holders of the
Series B Preferred Stock and to the holders of the Series A Preferred Stock, or
funds necessary for such payments shall have been set aside by the Corporation
in trust for the account of holders of Preferred Stock so as to be available for
such payments, the remaining assets available for distribution shall be
distributed among the holders of the Common Stock ratably in proportion to the
number of shares of Common Stock held by them.

     Upon conversion of shares of Series B Preferred Stock or Series A Preferred
Stock into shares of Common Stock pursuant to Section 2 below, the holder of
such Common Stock shall not be entitled to any preferential payment or
distribution in case of any liquidation, dissolution or winding up, but shall
share ratably in any distribution of the assets of the Corporation to all the
holders of Common Stock.

     The amounts payable with respect to shares of Series B Preferred Stock and
Series A Preferred Stock under this Section l(a) are sometimes hereinafter
referred to as "Series B Liquidation Payments" and "Series A Liquidation
Payments," respectively, and together are sometimes hereinafter referred to as
the "Liquidation Payments."

          (b) Distributions Other than Cash.  Whenever the distributions
              -----------------------------
provided for in this Section 1 shall be payable in property other than cash, the
value of such distributions shall be the fair market value of such property as
determined in good faith by the Board of Directors of the Corporation.

     Section 2.  Conversion.  The holders of Preferred Stock shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a) Right to Convert; Conversion Price.  Each share of Preferred 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
data of issuance of such share, at the office of the Corporation or any transfer
agent for the Preferred Stock, into such number of fully paid and nonassessable
shares of Common Stock as is determined in accordance with the following:

     of Common Stock shall be deliverable upon conversion of Series B Preferred
     Stock without the payment of any additional consideration by the holder

     share of Common Stock.  Such initial Series B Conversion Price shall be

                                      -3-
<PAGE>

     subject to adjustment, in order to adjust the number of shares of Common
     Stock into which the Series B Preferred Stock in convertible, as
     hereinafter provided.

               (ii)  in the case of the Series A Preferred Stock, by dividing

     in effect at the time of conversion.  The Conversion Price at which shares
     of Common Stock shall be deliverable upon conversion of Series A Preferred
     Stock without the payment of any additional consideration by the holder
     thereof (the "Series A Conversion Price") shall initially be $0.50 per
     share of Common Stock.  Such initial Series A Conversion Price shall be
     subject to adjustment, in order to adjust the number of shares of Common
     Stock into which the Series A Preferred Stock is convertible, as
     hereinafter provided.

          (b) Automatic Conversion.  Each share of Series B Preferred Stock
              --------------------
shall automatically be converted into shares of Common Stock at the applicable
Series B conversion Price then in effect upon:

               (i)   the closing of a firm commitment underwritten public
     offering pursuant to an effective registration statement under the
     Securities Act of 1933, an amended, covering the offer and sale of Common
     Stock for the account of the Corporation to the public at an offering price
     per share (prior to underwriter commissions and discounts) of not less than
     $4.50 (an adjusted pursuant to Subsection 2 (e) (vi) hereof to reflect any
     stock dividends, distributions, combinations, reclassifications or other
     like transactions effected by the Corporation in respect of its Common
     Stock) and with gross proceeds to the Corporation of not less than
     $10,000,000 (in the event of which offering, the person(s) entitled to
     receive the Common Stock issuable upon such conversion of the Series B
     Preferred Stock shall not be deemed to have converted that Series B
     Preferred Stock until the closing of such offering); or

               (ii)  the written election of the holders of not less than
     eighty-five percent (85%) of the then outstanding shares of the Series B
     Preferred Stock to require such mandatory conversion.

     Each share of Series A Preferred Stock shall automatically be converted
into shares of Common Stock at the applicable Series A Conversion Price then in
effect upon:

               (i)   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

     any stock dividends, distributions, combinations, reclassifications or
     other like transactions effected by the Corporation in respect of its
     Common Stock) and with gross proceeds to the Corporation of not lose than
     $10,000,000 (in the event of which offering, the person(s) entitled to
     receive the Common Stock issuable upon such conversion of the Series A
     Preferred Stock shall not be deemed to have converted that Series A
     Preferred Stock until the closing of such offering); or

                                      -4-
<PAGE>

               (ii)  the written election of the holders of not less than eighty
     percent (80%) of the then outstanding shares of the Series A Preferred
     Stock to require such mandatory conversion.

          (c) Mechanics of Automatic Conversions.  Upon the occurrence of an
              ----------------------------------
event specified in Subsection 2(b), the Series B Preferred Stock or the Series A
Preferred Stock, as applicable, or both, shall be converted automatically
without any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered to the Corporation or its
transfer agent; provided, however, that all holders of shares of Preferred Stock
being converted shall be given written notice of the occurrence of an event
specified in Subsection 2(b) including the date such event occurred (the
"Mandatory Conversion Date"), and the Corporation shall not be obligated to
issue certificates evidencing the shares of Common Stock issuable upon such
conversion unless certificates evidencing such shares of the Preferred Stock
being converted are either delivered to the Corporation or its transfer agent,
or the holder notifies the Corporation or any transfer agent that such
certificates have been lost, stolen, or destroyed and executes 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 bond.  On the Mandatory Conversion Date, all
rights with respect to the Preferred Stock so converted shall terminate, except
any of the rights of the holder thereof, upon surrender of the holder's
certificate or certificates therefor, to receive certificates for the number of
shares of Common Stock into which such Preferred Stock has been converted,
together with cash in an amount equal to all dividends declared but unpaid on,
and any and all other amounts owing with respect to, the shares of Preferred
Stock converted to and including the time of conversion.  Upon the automatic
conversion of the Preferred Stock, the holders of such Preferred Stock shall
surrender the certificates representing such shares at the office of the
Corporation or of its transfer agent.  If so required by the Corporation,
certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the
Corporation, duly executed by the registered holder or by the holder's attorney
duly authorized in writing.  Upon surrender of such certificates there shall be
issued and delivered to such holder, promptly at such office and in the 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
the Preferred Stock surrendered were convertible on the date on which such
automatic conversion occurred, together with cash in an amount equal to all
dividends declared but unpaid on, and any and all other amounts owing with
respect to, the shares of Preferred Stock converted to and including the time of
conversion.  No fractional share of Common Stock shall be issued upon the
mandatory conversion of the Preferred Stock.  In lieu of any fractional share to
which the holder would otherwise be entitled, the Corporation shall pay cash
equal to such fraction multiplied by the applicable Conversion Price then in
effect.

          (d) Mechanics of Optional Conversions.  Before any holder of Preferred
              ---------------------------------
Stock shall be entitled to convert the same into shares of Common Stock, the
holder shall surrender the certificate or certificates therefor at the office of
the Corporation or of any transfer agent for the Preferred Stock, and shall give
written notice to the Corporation at such office that the holder elects to
convert the same and shall state therein the holder's name or the name or names
of the holder's nominees in which the holder wishes the certificate or
certificates for shares of Common Stock to be issued.  On the date of
conversion, all rights with respect to the Preferred Stock so

                                      -5-
<PAGE>

converted shall terminate, except any of the rights of the holder thereof, upon
surrender of the holder's certificate or certificates therefor, to receive
certificates for the number of shares of Common Stock into which such Preferred
Stock has been converted and cash in an amount equal to all dividends declared
but unpaid thereon and any and all other amounts owing with respect thereto at
such time. If so required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by written instrument or instruments
of transfer, in form satisfactory to the Corporation, duly executed by the
registered holder or by the holder's attorney duly authorized in writing. No
fractional share of Common Stock shall be issued upon the optional conversion of
Preferred Stock. In lieu of any fractional share to which the holder would
otherwise be entitled, the Corporation shall pay cash equal to such fraction
multiplied by the applicable Conversion Price then in effect. The Corporation
shall, as soon as practicable after surrender of the certificate or certificates
for conversion, issue and deliver at such office to such holder of Preferred

                         (D) no readjustment pursuant to clause (B) or (C) above
               shall have the effect of increasing the Series B Conversion Price

               terms not more than 30 days after the date of issue thereof, no
               adjustment of the Series B Conversion Price or the Series A
               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 (C) above; and

               of business an such record date, and thereafter the respective
               Conversion Prices shall be adjusted pursuant to this Subsection
               2(e)(iii) as of the actual date of their issuance.

               such. 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 in the Series B Conversion Price and the
          Series A Conversion Price which became effective on such record date
          shall be cancelled as of the close of business on such record date,
          and thereafter the respective Conversion Prices shall be adjusted
          pursuant to this Section 2 (e) (iii) as of the time of actual payment
          of such dividend.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional

     issue of any Additional Shares of Common stock shall be computed as
     follows:

                         (1) Cash and Property.  Such consideration shall:

                             (A) 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;

                             (B) insofar as it consists of property other than
               cash, be computed at the fair value thereof at the time of such
               issue, as determined in good faith by the Board of Directors; and

                             (C) in the event 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 (A) and (B) above, as determined in good
               faith by the Board of Directors.

                    (2) Options and Convertible Securities.  The consideration
                        ----------------------------------

          Stock deemed to have been issued pursuant to Subsection 2 (e) (iii)
          (1) , relating to Options and Convertible securities, shall be
          determined by dividing (x) 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 (y) 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.

          the Series A Conversion Price in effect immediately before such deemed
          issuance shall, concurrently with the effectiveness of such deemed
          issuance, be proportionately decreased.

                    (2) Combinations or Consolidations.  In the event the
                        ------------------------------

          Common Stock, the Series B Conversion Price and the Series A
          Conversion Price in effect immediately prior to such combination or
          consolidation shall, concurrently with the effectiveness of such

that at any time or from time to time after the Original Issue Date the
Corporation shall make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive, a dividend or other distribution

and in each such event provision shall be made so that the holders of Preferred
Stock shall receive upon conversion thereof in addition to the number of shares
of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had their Preferred Stock been
converted into Common Stock an the date of such event and had they thereafter,
during the period from the date of such event to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period, giving application during such period to all adjustments called for
herein.

          (g) Adjustment for Reclassification, Exchange, or Substitution.  In
              ----------------------------------------------------------
the event that at any time or from time to time after the Original Issue Date,

changed into the same or a different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
above, or a merger, consolidation, or sale of assets provided for below), then
and in each such event the holder of any share or shares of Preferred Stock
shall have the right thereafter to convert such shares into the kind and amount
of shares of stock and other securities and property receivable upon such
reorganization, reclassification, or other change, by the holder of a number of
shares of Common Stock equal to the number of shares of Common Stock into which
such shares of Preferred Stock might have been converted immediately prior to
such reorganization, reclassification, or change, all subject to further
adjustment as provided herein.

          (h) Adjustment for Merger, Consolidation or Sale of Assets.  In the
              ------------------------------------------------------
event that at any time or from time to time after the Original Issue Date, the
Corporation shall merge or consolidate with or into another entity or sell all
or substantially all of its assets, each share of Preferred Stock as to which
such consolidation, merger or sale is not treated as a liquidation

                                     -11-
<PAGE>

under Subsection l(c) shall thereafter be convertible into the kind and amount
of shares of stock or other securities or property to which a holder of the
number of shares of Common Stock of the Corporation deliverable upon conversion
of such Preferred Stock would have been entitled to receive upon such
consolidation, merger or sale; and, in such case, appropriate adjustment (as
determined in good faith by the Board of Directors) shall be made in the
application of the provisions set forth in this Section 2 with respect to the
rights and interest thereafter of the holders of Preferred Stock, to the end
that the provisions set forth in this Section 2 (including provisions with
respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly an reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
Preferred Stock.

              -------------
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 2 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

              ----------------------------
adjustment or readjustment of the Series B Conversion Price or the Series A
Conversion Price pursuant to this Section 2, 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 Preferred Stock 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 Preferred
Stock, furnish or cause to be furnished 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 the
conversion of each share of Preferred Stock.

              ----------------------
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 Preferred Stock 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.

of Common Stock as shall from time to time be sufficient to affect conversion of
the Preferred Stock.

has funds legally available for such purpose, up to a number of shares of Series
B Preferred Stock equal to such holder's Pro Rata Redemption Amount (as
hereinafter defined) at a redemption price of $1.50 per share.  Such election
may be made only by delivering to the Corporation within thirty (30) days after

number of shares of Series B Preferred Stock so to be redeemed (which number
shall be not more than such holder's Pro Rata Redemption Amount), and (ii)
certificates for the shares of Series B Preferred Stock so to be redeemed,
together with stock powers therefor duly executed by such holder in blank.

          (c) For purposes of this Section 6, each holder of Series B Preferred

Proceeds, and the denominator or which is the product of the total number of
shares of Series B Preferred Stock issued and outstanding times $1.50.

electing holders of Series B Preferred Stock the shares of Series B Preferred
Stock as to which election notices have been properly given, to the extent the
Corporation has funds legally available for such purpose.

          (e) If the funds of the Corporation legally available for redemption
of shares of Series B Preferred Stock on the Redemption Date are insufficient to
redeem the total number of shares of Series B Preferred Stock submitted for
redemption, those funds which are legally available will be used to redeem the
maximum possible number of whole shares ratably among the holders of such shares
in accordance with the manner of determining the "Pro Rata Redemption Amount"
set forth above.  The shares of Series B Preferred Stock not redeemed shall
remain outstanding and entitled to all rights and preferences provided herein.

days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting.

     3.10  Proxy Representation.  Every stockholder may authorize another person
           --------------------
or persons to act for him by proxy in all matters in which a stockholder is
entitled to participate, whether by waiving notice of any meeting, objecting to
or voting or participating at a meeting, or expressing consent or dissent
without a meeting.  Every proxy must be signed by the stockholder or by his
attorney-in-fact.  No proxy shall be voted or acted upon after three years from
its date unless such proxy provides for a longer period.  Except as provided by
law, a revocable proxy shall be deemed revoked if the stockholder is present at
the meeting for which the proxy was given.  A duly executed proxy shall be
irrevocable if it states that it is irrevocable and, if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power.
A proxy may be made irrevocable regardless of whether the interest with which it
is coupled is an interest in the stock itself or an interest in the corporation
generally.  The authorization of a proxy may but need not be limited to
specified action, provided, however, that if a proxy limits its authorization to
a meeting or meetings of stockholders, unless otherwise specifically provided
such proxy shall entitle the holder thereof to vote at any adjourned session but
shall not be valid after the final adjournment thereof.

     3.11  Inspectors.  The directors or the person presiding at the meeting
           ----------
may, but need not, appoint one or more inspectors of election and any substitute
inspectors to act at the meeting or any adjournment thereof.  Each inspector,
before entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspector at such meeting with strict
impartiality and according to the best of his ability.  The inspectors, if any,
shall determine the number of shares of stock outstanding and the voting power
of each, the shares of stock represented at the meeting, the existence of a
quorum and the validity and effect of proxies, and shall receive votes, ballots
or consents, hear and determine all challenges and questions arising in
connection with the right to vote, count and tabulate all votes, ballots or
consents, determine the result, and do such acts as are proper to conduct the
election or vote with fairness to all stockholders.  On request of the person
presiding at the meeting, the inspectors shall make a report in writing of any
challenge, question or matter determined by them and execute a certificate of
any fact found by them.

     3.12  Action by Vote.  When a quorum is present at any meeting, whether the
           --------------
same be an original or an adjourned session, a plurality of the votes properly
cast for election to any office shall elect to such office and a majority of the
votes properly cast upon any question other than an election to an office shall
decide the question, except when a larger vote is required by law, by the
certificate of incorporation or by these by-laws.  No ballot shall be required
for any election unless requested by a stockholder present or represented at the
meeting and entitled to vote in the election.

without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted.  Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

shall determine the number of directors, and within such limits, the number of
directors may be increased or decreased at any time or from time to time by the
stockholders or by the directors by vote of a majority of directors then in
office, except that any such decrease by vote of the directors shall only be
made to eliminate vacancies existing by reason of the death, resignation or
removal of one or more directors.  The directors shall be elected at the annual
meeting of the stockholders, except as provided in Section 4.4 of these by-laws.
Directors need not be stockholders.

     4.2  Tenure.  Except as otherwise provided by law, by the certificate of
          ------

     4.3  Powers.  The business of the corporation shall be managed by or under
          ------

to be exercised or done by the stockholders.

     4.4  Vacancies.  Vacancies and any newly created directorships resulting
          ---------
from any increase in the number of directors may be filled by vote of the

directors then in office, although less than a quorum, or by a sole remaining
director.  When one or more directors shall resign from the board, effective at
a future date, a majority of the directors then in office, including those who
have resigned, shall have power to fill such vacancy or vacancies, the vote or
action by writing thereon to take effect when such resignation or resignations
shall become effective.  The directors shall have and may exercise all their

these by-laws as to the number of directors required for a quorum or for any
vote or other actions.

the business and affairs of the corporation, including the power to authorize
the seal of the corporation to be affixed to all papers which require it and the
power and authority to declare dividends or to authorize the issuance of stock;
excepting, however, such powers which by law, by the certificate of
incorporation or by these by-laws they are prohibited from so delegating. In the
absence or disqualification of any member of such committee and his alternate,
if any, the member or members thereof present at any meeting and not
disqualified from voting, whether or not constituting a quorum, may unanimously
appoint another member of the board of directors to act at the meeting in the
place of any such absent or disqualified member. Except as the board of
directors may otherwise determine, any committee may make rules for the conduct
of its business, but unless otherwise provided by the board or such rules, its
business shall be conducted as nearly as may be in the same manner as is
provided by these by-laws for the conduct of business by the board of directors.
Each committee shall keep regular minutes of its meetings and report the same to
the board of directors upon request.

     4.6  Regular Meeting.  Regular meetings of the board of directors may be
          ---------------
held without call or notice at such place within or without the State of
Delaware and at such times as the board may from time to time determine,

send notice by mail at least forty-eight hours or by telegram at least twenty-
four hours before the meeting, addressed to him at his usual or last known
business or residence address or to give notice to him in person or by telephone
at least twenty-four hours before the meeting.  Notice of a meeting need not be
given to any director if a written waiver of notice, executed by him before or
after the meeting, is filed with the records of the meeting, or to any director
who attends the meeting without protesting prior thereto or at its commencement
the lack of notice to him.  Neither notice of a meeting nor a waiver of a notice
need specify the purposes of the meeting.

     4.9  Quorum.  Except as may be otherwise provided by law, by the
          ------
certificate of incorporation or by these by-laws, at any meeting of the
directors a majority of the directors then in office shall constitute a quorum;

the board of directors.

           ------------------------
certificate of incorporation or these by-laws, any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting if all the members of the board or of such
committee, as the case may be, consent thereto in writing, and such writing or
writings are filed with the records of the meetings of the board or of such
committee.  Such consent shall be treated for all purposes as the act of the
board or of such committee, as the case may be.

     4.12  Participation in Meetings by Conference Telephone.  Unless otherwise
           -------------------------------------------------
restricted by the certificate of incorporation or these by-laws, members of the
board of directors or of any committee thereof may participate in a meeting of
such board or committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other.  Such participation shall constitute presence in
person at such meeting.

           ------------
incorporation or these by-laws, the board of directors shall have the authority
to fix from time to time the compensation of directors.  The directors may be
paid their expenses, if any, of attendance at each meeting of the board of
directors and the performance of their responsibilities as directors and may be
paid a fixed sum for attendance at each meeting of the board of directors and/or
a stated salary as director.  No such payment shall preclude any director from

capacity and receiving compensation therefor.  The board of directors may also

corporation, partnership, association, or other organization in which one or
more of the corporations, directors or officers are directors or officers, or
have a financial interest, shall be void or voidable solely for this reason, or
solely because the director or officer is present at or participates in the
meeting of the board or committee thereof which authorizes the contract or
transaction, or solely because his or their votes are counted for such purpose,
if:

          (1) The material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the board of directors
or the committee, and the board or committee in good faith authorizes the
contract or transaction by the affirmative votes of a majority of the

quorum; or

                                      -5-
<PAGE>

          (2) The material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the stockholders
entitled to vote thereon, and the contract or transaction is specifically

          (3) The contract or transaction is fair as to the corporation as of
the time it is authorized, approved or ratified, by the board of directors, a
committee thereof, or the stockholders.

          (b) Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the board of directors or of a committee
which authorizes the contract or transaction.

the certificate of incorporation or by law, any director or the entire board of
directors may be removed, with or without cause, by the holders of a majority of
the stock issued and outstanding and entitled to vote at an election of
directors.  Any director may resign at any time by delivering his resignation in
writing to the president or the secretary or to a meeting of the board of
directors.  Such resignation shall be effective upon receipt unless specified to
be effective at some other time; and without in either case the necessity of its
being accepted unless the resignation shall so state.  No director resigning and
(except where a right to receive compensation shall be expressly provided in a
duly authorized written agreement with the corporation) no director removed
shall have any right to receive compensation as such director for any period
following his resignation or removal, or any right to damages on account of such
removal, whether his compensation be by the month or by the year or otherwise;
unless in the case of a resignation, the directors, or in the case of removal,
the body acting on the removal, shall in their or its discretion provide for
compensation.

                     Form of Registration Rights Agreement
                     -------------------------------------
<PAGE>

                         REGISTRATION RIGHTS AGREEMENT

     This Registration Rights Agreement is entered into as of May __,1997 by and
among Sequenom, Inc., a Delaware corporation (the "Corporation"); the holders
(the "Series B Investors") of shares of the Corporation's Series B Convertible
Preferred Stock, $.001 par value per share (the Series B Preferred Stock"); and
the purchasers of shares of the Corporation's Series C Convertible Preferred
Stock, par value $.001 per share (the "Series C Preferred Stock"), pursuant to
the Series C Convertible Preferred Stock Purchase Agreement dated as of the date
hereof (the "Purchase Agreement"), including any Additional Investors as defined
in the Purchase Agreement (such purchasers of Series C Preferred Stock being
hereinafter sometimes referred to individually as an "Investor" and collectively
as the "Investors").

     WHEREAS, the Corporation and the Series B Investors are the parties to a
Registration Rights Agreement dated as of December 22, 1995 (the "Prior
Registration Rights Agreement"), pursuant to which the Corporation granted
certain registration rights to the Series B Investors and certain of their
transferees;

     WHEREAS, the Corporation now wishes to sell to the Investors certain shares
of its Series C Preferred Stock and certain warrants to purchase shares of its
Series C Preferred Stock;

     WHEREAS, the Series B Preferred Stock and the Series C Preferred Stock are
convertible into shares of the Corporation's Common Stock; and

     WHEREAS, as a condition to entering into the Purchase Agreement, the
Investors have required that the Corporation and the Series B Investors execute
this Agreement to provide the Investors rights to register the shares of Common
Stock issuable upon conversion of their Series C Preferred Stock and certain
other securities of the Corporation described below;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
hereinafter set forth, the parties hereto agree as follows:

     1.  Definitions.  As used in this Agreement, the following terms shall have
         -----------
the following meanings:

     (a) The term "Act" means the Securities Act of 1933, as amended;

     (b) The term "Holder" means any Investor, any Series B Investor and any
other person or entity holding Registrable Securities to whom the registration
rights granted in this Agreement have been transferred pursuant to Section 14
hereof;

     (c) The term "Preferred Stock" means the Series B Preferred Stock and the
Series C Preferred Stock;

     (d) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement; and
<PAGE>

     (e) The term "Registrable Securities" means (1) the Common Stock issuable
upon conversion of the Preferred Stock, (2) Common Stock purchased by an
Investor pursuant to Section 8.1 of the Purchase Agreement (or Common Stock for
or into which New Securities (as therein defined) purchased by the Investor
pursuant to such Section 8.1 may be exercised or converted) or pursuant to the
Stock Restriction Agreement dated as of the date hereof among the Corporation,
the Series B Investors, the Investors and certain additional parties identified
therein, and (3) any Common Stock of the Corporation issued as a dividend or
other distribution with respect to, or in exchange or in replacement of, such
Preferred Stock or Common Stock.

     In addition, for purposes of all calculations and notices under this
Agreement, and all other provisions of this Agreement where the context permits,
the term "Registrable Securities" shall include securities issuable upon
conversion of the Preferred Stock, a holder of the Preferred Stock shall be
deemed the Holder of such securities and such securities shall be deemed
outstanding Registrable Securities hereunder.  Notwithstanding the foregoing,
nothing in this Agreement shall require the Corporation actually to register any
shares of the Preferred Stock.

     2.  Request for Registration.  If at any time after the earlier of (i) the
         ------------------------
first underwritten public offering of securities for the account of the
Corporation, and (ii) the date three (3) years from the date hereof, the
Corporation shall receive a written request (specifying that it is being made
pursuant to this Section 2) from the Holder or Holders at least fifty percent
(50%) of the then outstanding Registrable Securities that the Corporation file a
registration statement under the Act, or a similar document pursuant to any
other statute then in effect corresponding to the Act, covering the registration
of at least the lesser of (i) at least twenty-five percent (25%) of the then
outstanding Registrable Securities and (ii) Registrable Securities the expected
price to the public of which equals or exceeds $10,000,000, then the Corporation
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that Holders have requested be
registered to be registered under the Act.

     Notwithstanding the foregoing, (a) the Corporation shall not be obligated
to effect a registration pursuant to this Section 2 during the period starting
with the date sixty (60) days prior to the Corporation's estimated date of
filing of, and ending on a date six (6) months following the effective date of,
a registration statement pertaining to an underwritten public offering of
securities for the account of the Corporation, provided that the Corporation is
actively employing in good faith its best efforts to cause such registration
statement to become effective and that the Corporation's estimate of the date of
filing such registration statement is made in good faith; (b) the Corporation
shall not be obligated to effect a registration pursuant to this Section 2
within six (6) months after the effective date of a prior registration under
such Section; (c) if the Corporation shall furnish to the Holders a certificate
signed by the President of the Corporation stating that in the good faith
judgment of the Board of Directors it would be seriously detrimental to the
Corporation or its shareholders for a registration statement to be filed in the
near future, then the Corporation's obligation to use its best efforts to file a
registration statement shall be deferred for a period not to exceed three (3)
months; and (d) the Corporation may postpone a registration pursuant to this
election for such period of time as may be required to permit the use of regular
audited year-end financial statements with supplemental short period figures for
a period not exceeding six (6) months unless the Holders agree to bear the costs
of any special audit.

                                       2
<PAGE>

     The Corporation shall not be obligated to effect more than two (2)
registrations pursuant to this Section 2. Any request for registration under
this Section 2 must be for a for a firm commitment underwritten public offering
to be managed by an underwriter or underwriters of recognized national standing
reasonably acceptable to the Corporation.

     3.  Corporation Registration.  Subject to Section 8 of this Agreement, if
         ------------------------
at any time the Corporation proposes to register any of its Common Stock under
the Act in connection with the public offering of such securities for its own
account or for the accounts of other shareholders, solely for cash on a form
that would also permit the registration of the Registrable Securities, the
Corporation shall, each such time, promptly give each Holder written notice of
such determination.  Upon the written request of any Holder given within thirty
(30) days after mailing of any such notice by the Corporation, the Corporation
shall, subject to the limitations set forth in Section 8(a), use its best
efforts to cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested be registered.

     4.  Obligations of the Corporation.  Whenever required under Section 2, 3,
         ------------------------------
or 11 to use its best efforts to effect the registration of any Registrable
Securities, the Corporation shall, as expeditiously as reasonably possible:

     (a) Prepare and file with the Securities and Exchange Commission ("SEC") a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a so-
called "shelf registration"), the Corporation shall in no event be obligated to
cause any such registration to remain effective for more than one hundred eighty
(180) days.

     (b) Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

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

     (d) Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Corporation
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by selling shareholders pro rata, to the extent
required by such jurisdiction.

                                       3
<PAGE>

     (e) Provide a transfer agent for the Common Stock no later than the
effective date of the first registration of any Registrable Securities.

     5.  Furnish information.  It shall be a condition precedent to the
         -------------------
obligations of the Corporation to take any action pursuant to this Agreement
that the Holders shall furnish to the Corporation such information regarding
them, the Registrable Securities held by them, and the intended method of
disposition of such securities as the Corporation shall reasonably request and
as shall be required in connection with the action to be taken by the
Corporation.

     6.  Expenses of Demand Registration.  All expenses incurred in connection
         -------------------------------
with registrations pursuant to Section 2 (excluding underwriters' discounts and
commissions), including, without limitation, all registration and qualification
fees, printers, and accounting fees, fees and disbursements of counsel for the
Corporation, and the reasonable fees and disbursements of one special counsel
for the selling Holders, shall be borne by the Corporation.

     7.  Corporation Registration Expenses.  All expenses (excluding
         ---------------------------------
underwriters' discounts and commissions) incurred in connection with a
registration pursuant to Section 3, including, without limitation, any
additional registration and qualification fees and any additional fees and
disbursements of counsel to the Corporation that result from the inclusion of
securities held by the Holders in such registration and the reasonable fees and
disbursements of one special counsel for the selling stockholders, shall be bore
by the Corporation; provided, however, that if the registration is of
exclusively a secondary offering, the holders shall bear their proportionate
share of the expenses incurred in connection with any registration (provided all
shareholders registering shares thereunder bear their proportionate share of
expenses), except expenses which the Corporation would have incurred whether or
not the securities held by the Holders were included in such registration
(including, without limitation, the expense of preparing normal audited or
unaudited financial statements).

     8.  Underwriting Requirements.
         -------------------------

     (a) In connection with any offering involving an underwriting of shares
being issued by the Corporation, the Corporation shall not be required under
Section 3 to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Corporation and the underwriters selected by it, and then only in
such quantity as will not, in the reasonable opinion of the underwriters,
jeopardize the success of the offering by the Corporation.  If the total amount
of securities that all Holders request to be included in an underwritten
offering exceeds the amount of securities that the underwriters reasonably
believe compatible with the success of the offering, the Corporation shall only
be required to include in the offering so many of the securities of the selling
Holders as the underwriters reasonably believe will not jeopardize the success
of the offering (the securities so included to be apportioned pro rata among the
selling Holders according to the total amount of securities owned by said
selling Holders, or in such other proportions as shall mutually be agreed to by
such selling Holders), provided that in the case of an offering involving shares
being issued by the Corporation, no such reduction shall be made with respect to
any securities offered by the Corporation for its own account, and provided
further that no securities of any shareholder who is not a Holder shall be
included in such offering, other than securities of shareholders who have
initiated such registration pursuant to the exercise of contractual rights to

                                       4
<PAGE>

do so, unless all securities which the Holders have requested to be included are
included on a pro rata basis with the securities of any other shareholders who
have a contractual right to include their securities in such offering.

     (b) With respect to any underwriting of shares to be registered under
Section 2, or an underwriting of shares to be registered under Section 11 if the
Holders of a majority of the then outstanding Registrable Securities have
requested registration thereunder, such Holders shall have the right to
designate the managing underwriter or underwriters, subject to the consent of
the Corporation.  In all other circumstances under such Sections and in
connection with registrations under Section 3, the Corporation shall have the
right to designate the managing underwriter or underwriters, subject to the
consent of the Holders of a majority of the Registrable Securities participating
in the underwriting.  In any such case, such consent shall not be unreasonably
withheld or delayed.

     9.  Delay of Registration.  No Holder shall have any right to take any
         ---------------------
action to restrain, enjoy, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Agreement.

     10.  Indemnification.  In the event any Registrable Securities are included
          ---------------
in a registration statement under this Agreement:

     (a) To the extent permitted by law, the Corporation will indemnify and hold
harmless each Holder requesting or joining in a registration, any underwriter
(as defined in the Act) for it, and each person, if any, who controls such
Holder or underwriter within the meaning of the Act, against any losses, claims,
damages or liabilities, joint or several, to which they 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 on any untrue or alleged
untrue statement of any material fact contained in such registration statement,
including, without limitation, any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, 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 or arise out of any violation by the Corporation of any rule or
regulation promulgated under the Act applicable to the Corporation and relating
to action or inaction required of the Corporation in connection with any such
registration; and will reimburse each such Holder, such underwriter, or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability, or action, provided, however, that the indemnity agreement contained
in this Section 10(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 Corporation (which consent shall not be unreasonably withheld
or delayed) nor shall the Corporation be liable in any such case for any such
loss, claim, damage, liability or action to the extent that it arises out of or
is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus, or amendments or supplements thereto,
in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by any such Holder, underwriter or
controlling person.

                                       5
<PAGE>

     (b) To the extent permitted by law, each Holder requesting or joining in a
registration will indemnify and hold harmless the Corporation, each of its
directors, each of its officers who has signed the registration statement, each
person, if any, who controls the Corporation within the meaning of the Act, and
any underwriter for the Corporation (within the meaning of the Act) against any
losses, claims, damages or liabilities to which the Corporation or any such
director, officer, controlling person or underwriter may become subject, under
the Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, 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,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such
registration statement, preliminary prospectus or final prospectus, or
amendments or supplements thereto, in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and will reimburse the Corporation or any such director,
officer, controlling person or underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 10(b) 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 such Holder (which consent shall
not be unreasonably withheld) and provided further that no Holder shall have any
liability under this Section 10(b) in excess of the net proceeds actually
received by such Holder in the relevant public offering.

     (c) Promptly after receipt by an indemnified party under this Section 10 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 10, notify the indemnifying party in writing of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties.  The failure to notify an indemnifying party
promptly, of the commencement of any such action, if prejudicial to his ability
to defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 10, but the omission so to notify the
indemnifying party will not relieve him of any liability that he may have to any
indemnified party otherwise than under this Section 10.

     11.  Registrations on Form S-3.
          -------------------------

     (a) If (i) the Corporation shall receive a written request (specifying that
it is being made pursuant to this Section 11) from the Holder or Holders of at
least twenty-five percent (25%) of the then outstanding Registrable Securities
that the Corporation file a registration statement on Form S-3 (or any successor
form to Form S-3 regardless of its designation) for a public offering of shares
of the Registrable Securities the reasonably anticipated aggregate price to the
public of which would exceed Two Million Dollars ($2,000,000), and (ii) the
Corporation is a registrant entitled to use Form S-3 to register such shares,
then the Corporation shall use its

                                       6
<PAGE>

best efforts to cause such shares to be registered on Form S-3 (or any successor
form to Form S-3).

     (b) All expenses (excluding underwriters' discounts and commissions)
incurred in connection with the first two registrations requested pursuant to
Section 11(a), including, without limitation, all registration, qualification,
printing, and accounting fees, and fees and disbursements of one special counsel
to the selling Holder or Holders and counsel to the Corporation, shall be borne
by the Corporation.  All such expenses for registrations pursuant to Section
11(a) after the first two such registrations shall be borne by the Corporation,
except that the selling Holders shall pay all fees of their legal counsel, if
any, in connection therewith.

     (c) Holders' rights to registration under this Section 11 are in addition
to, and not in lieu of, their rights to registration under Sections 2 and 3 of
this Agreement.

     12.  Reports Under Securities Exchange Act of 1934.  With a view to making
          ---------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Corporation to the public without registration, the
Corporation agrees to use its best efforts to:

     (a) make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Corporation;

     (b) file with the SEC in a timely manner all reports and other documents
required of the Corporation under the Act and the Securities Exchange Act of
1934, as amended (the "1934 Act"); and

     (c) furnish to any Holder forthwith upon request a written statement by the
Corporation that it has complied with the reporting requirements of Rule 144 (at
any time after ninety (90) days after the effective date of said first
registration statement filed by the Corporation), and of the Act and the 1934
Act (at any time after it has become subject to such reporting requirements), a
copy of the most recent annual or quarterly report of the Corporation, and such
other reports and documents so filed by the Corporation as may be reasonably
requested in availing any such holder to take advantage of any rule or
regulation of the SEC permitting the selling of any such securities without
registration.

     13.  Limitations in Connection with Future Grants of Registration Rights.
          -------------------------------------------------------------------
Without the prior written consent of the Holder or Holders of a majority of the
then outstanding Registrable Securities issued or issuable upon conversion of
the Preferred Stock, the Corporation shall not grant rights to cause the
Corporation to register any of its securities to any person or entity other than
the Additional Investors as contemplated hereunder.

     14.  Transfer of Registration Rights.  The registration rights of any
          -------------------------------
Investor (and of any permitted transferee of any Investor or its permitted
transferees) under this Agreement with respect to any shares of Registrable
Securities may be transferred to any Affiliate of such Investor or such
permitted transferee, or to any transferee who acquires (otherwise than in a
registered public offering) at least five percent (5%) of the Registrable
Securities held or acquired as of the date hereof by such Investor, provided,
however, that the Corporation is given
<PAGE>

written notice by the Holder at the time of such transfer stating the name and
address of the transferee and identifying the securities with respect to which
the rights under this Agreement are being assigned. For such purpose, an
"Affiliate" of any Investor (or any such transferee) means any partner of such
Investor (or transferee) if it is a partnership, or any person or entity that,
directly or indirectly, through one or more intermediaries, controls, or is
controlled by, or is under common control with, such Investor or transferee.

     15.  Mergers, Etc.  The Corporation shall not, directly or indirectly,
          ------------
enter into any merger, consolidation or reorganization in which the Corporation
shall not be the surviving corporation unless the proposed surviving corporation
shall, prior to such merger, consolidation or reorganization, agree in writing
to assume the obligations of the Corporation under this Agreement, and for that
purpose references hereunder to "Registrable Securities" shall be deemed to be
references to the securities which the Holders would be entitled to receive in
exchange for Registrable Securities under any such merger, consolidation or
reorganization; provided, however, that the provisions of this Agreement shall
not apply in the event of any merger, consolidation or reorganization in which
the Corporation is not the surviving corporation if the Holders of Registrable
Securities are entitled to receive in exchange therefor (i) cash, or (ii)
securities of the acquiring corporation which may be immediately sold to the
public without registration under the Act.

     16.  Stand-Off Agreement.  Each Holder, if requested by the Corporation and
          -------------------
the managing underwriter of an offering by the Corporation of Common Stock or
other securities of the Corporation pursuant to a registration statement under
the Act, shall agree not to sell publicly or otherwise transfer or dispose of
any Registrable Securities or other securities of the Corporation held by such
Holder for a specified period of time (not to exceed 180 days) following the
effective date of such registration statement; provided, that:
                                               --------

     (a) such agreement shall only apply to the first registration statement
covering Common Stock to be sold on the Corporation's behalf to the public in an
underwritten offering; and

     (b) all holders of five percent (5%) or more of the shares of Common Stock
then outstanding (including shares of Common Stock issuable upon the conversion
of Preferred Stock, or other convertible securities, or upon the exercise of
options, warrants or rights) and all officers and directors of the Corporation
enter into similar agreements.

     17.  Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     18.  Notices.  All notices, requests, consents and other communications
          -------
hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by first class mail postage
prepaid (other than to non-U.S. parties) or by fax or DHL, Federal Express or
other internationally recognized courier service, addressed to such party at the

                               VOTING AGREEMENT

     Agreement made as of May ___, 1997 by and among Sequenom, Inc., a Delaware

Patterson (the "Founders"); TVM Techno Venture Enterprises No. II Limited
Partnership, TVM Intertech Limited Partnership, TVM Zweite Beteiligung-U.S.
Limited Partnership, TVM Eurotech Limited Partnership, TVM Techno Venture
Investors No. 1 Limited Partnership and KBL Founder Ventures SCA (the "Original
Investors"); the holders (the "Series B Investors") of shares of the
Corporation's Series B Convertible Preferred Stock, $.001 par value per share
(the "Series B Preferred Stock"); and the purchasers of shares of the
Corporation's Series C Convertible Preferred Stock, $.001 par value per share
("Series C Preferred Stock"), pursuant to the Series C Convertible Preferred
Stock Purchase Agreement dated as of the date hereof (the "Purchase Agreement"),
including any Additional Investors as defined in the Purchase Agreement (all
such purchasers of Series C Preferred Stock under the Purchase Agreement being
referred to as the "Investors," and all such Founders, Original Investors,
Series B Investors and Investors being referred to as the "Stockholders").

                                   AGREEMENT
                                   ---------

     In consideration of the mutual covenants herein contained, the parties
hereto agree as follows:

     1.  Board of Directors.  The Stockholders agree to vote all shares of the
         ------------------
Corporation's Common Stock, $.001 par value per share ("Common Stock"), Series A
Convertible Preferred Stock, $.001 par value per share ("Series A Preferred
Stock"), Series B Preferred Stock, Series C Preferred Stock and any other class
of voting security of the Corporation (the "Shares") now or hereafter owned or
controlled by them, and otherwise to use their respective best efforts as
stockholders of the Corporation, to set the number of directors of the
Corporation at seven and to elect as directors, on the date of this Agreement
and in any subsequent election of directors of the Corporation:

     (a)  the Chief Executive Officer of the Corporation (the "CEO Director"),
          who shall initially be Fareed Kureshy;

     (b)  one person designated by the Founders, who shall initially be Hubert
          Koster;

     (c)  one person designated by the Original Investors, who shall initially
          be Helmut Schuhsler;

     (d)  two persons designated by the Series B Investors, who shall initially
          be Thomas Bologna and William Golden; and

     (e)  two persons who are not employees of the Corporation (the "Independent
          Directors"), who have experience in the Corporation's industry and who
          are reasonably acceptable to a majority of the other directors, and
          who shall initially be Nola E. Masterson and Ernst-Gunter Afting.

<PAGE>

     Any person or entity or group of persons or entities entitled to make a
director designation hereunder (a "Designating Party") shall furnish written
notice to the Stockholders at least 10 days prior to any election of directors
of its director-designee or director-designees.  In the absence of such notice,
the director-designee or director-designees of such Designating Party then
serving and previously designated shall be reelected if still eligible to serve
as provided herein.  In the event that any Designating Party that is a group of
Stockholders cannot agree upon a director-designee, the identity of the
director-designee of such Designating Party shall be determined by a plurality
in voting power of the outstanding capital stock of the Corporation held by the
Stockholders constituting such Designating Party.

     This Agreement is not intended, and shall not be construed, to confer upon
any person designated hereunder for election to the Board of Directors any right
to serve or to continue to serve in such capacity.  Any Designating Party may,
at any time, determine to remove its then-current director-designee and
designate another person for election to the Board of Directors in place of the
person then serving as the director-designee of such Designating Party.  In the
event any such determination is made, the Stockholders shall promptly vote to
remove the director-designee of such Designating Party then serving, and to
elect as a director the replacement director-designee of such Designating Party.

     If at any time the person serving as Chief Executive Officer of the
Corporation shall resign, be removed or otherwise cease to serve as such
officer, the Stockholders shall promptly vote (i) if the former Chief Executive
Officer has not resigned as a director, to remove him as a director, and (ii) to
elect the new Chief Executive Officer of the Corporation as the CEO Director.

     At any time a majority of the directors other than the Independent
Directors may determine to remove any Independent Director from the Board of
Directors and designate another person for election to the Board of Directors in
place of the person then serving as such Independent Director.  In the event any
such determination is made, the Stockholders shall promptly vote to remove the
applicable Independent Director and to elect as a director the replacement
Independent Director designee.

     Any vacancy on the Board of Directors created by the resignation, removal,
incapacity, or death of any person designated under this Section 1 shall be
filled by another person designated by the original Designating Party.  The
Stockholders shall vote their respective Shares in accordance with such new
designation, and any such vacancy shall not be filled in the absence of a new
designation by the original Designating Party.

     This Section 1 shall terminate and be of no further force and effect upon
the closing of a firm commitment underwritten public offering of Common Stock of
the Corporation pursuant to an effective registration statement under the
Securities Act of 1933, as amended, in which the aggregate gross proceeds to the
Corporation from such offering are not less than $20,000,000 and the offering
price per share is not less than $9.45, appropriately adjusted to take account
of any stock split, stock dividend, combination of shares or similar event.

     In the event that any Designating Party (or its or their respective
partners, stockholders and affiliates) owns, in the aggregate, fewer than
200,000 shares of the Corporation's Common

                                       2

Stock, subject to adjustment for stock splits, stock dividends, combinations of
shares and similar events, such Designating Party's right to make designations
under this Section 1 shall terminate, and the obligation of the other parties
under this Section 1 to vote for any members of the Board of Directors
designated by such Designating Party shall terminate, but all other obligations
of all parties hereunder shall continue unless otherwise terminated. For
purposes of this paragraph, in determining the number of shares of Common Stock
owned by a Designating Party, ownership by such Designating Party of shares of
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
shall be deemed to be ownership by it of that number of shares of Common Stock
into which such shares of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock are convertible.

     2.  Director Indemnification.  In the event that any director contemplated
         ------------------------
by this Agreement shall be made or threatened to be made a party to any action,
suit or proceeding with respect to which he may be entitled to indemnification
by the Corporation pursuant to its Certificate of Incorporation, By-Laws or
otherwise, he shall be entitled to be represented in such action, suit or
proceeding by counsel of his choice and the expenses of such representation
shall be reimbursed by the Corporation to the extent provided in or authorized
by said Certificate of Incorporation or other provision and permitted by
applicable law.

     The Corporation and the Stockholders agree not to take any action to amend
any provision of the Certificate of Incorporation or By-Laws of the Corporation
relating to indemnification of directors, as presently in effect, without the
prior written consent of a majority in voting power of the Series B Investors.

     3.  Accession.  Any Additional Investors as defined in the Purchase
         ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" and a
"Stockholder" for all purposes of this Agreement.

     4.  Notices.  All notices, requests, consents and other communications
         -------
hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by first class mail postage
prepaid (other than to non-U.S. parties), by fax, or by DHL, Federal Express or
any other internationally recognized express courier service, addressed to such

     5.   Assignment; Binding Effect.  No Designating Party may assign its or
          --------------------------
their rights hereunder.  Subject to termination or partial termination as
provided in Section 1, this Agreement shall be binding on the parties hereto and
their respective legal representatives, successors and permitted assigns and on
the transferees of any Shares now owned or hereafter acquired by them.

     6.   Entire Agreement; Amendment and Waiver.  This Agreement contains the
          --------------------------------------
sole and entire understanding of the parties with respect to its subject matter
and supersedes all prior negotiations, commitments, agreements and
understandings heretofore had among any of them with respect thereto.  Without
limiting the generality of the foregoing, this Agreement supersedes and replaces
the Voting Agreement among the Corporation, the Founders, the Original Investors
and the Series B Investors dated as of December 22, 1995, which shall no longer
have any force or effect.  This Agreement may not be changed or terminated or
any performance or condition waived, in whole or in part, except by the written
agreement of the Corporation and Stockholders or transferees of their rights
hereunder holding two-thirds in voting power of the Shares held by the Founders,
two-thirds in voting power of the Shares held by the Original Investors, eighty-
five percent (85%) in voting power of the Shares held by the Series B Investors,
and two-thirds in voting power of the Shares held by the Investors.  A waiver on
one occasion shall not constitute a waiver on any further occasion.

     7.   Counterpart.  This Agreement may be executed in more than one
          -----------
counterpart, each of which shall be deemed to be an original and which,
together, shall constitute one and the same instrument.  Any such counterpart
may contain one or more signature pages.

     8.   Applicable Law.  This Agreement shall be governed by, and construed
          --------------
and enforced in accordance with, the substantive laws of The Commonwealth of
Massachusetts, without regard to its principles of conflicts of laws.

     9.   Legend. Each certificate for Shares shall bear a legend stating in
          ------
substance as follows, and each of the Stockholders shall cause its certificates
to be so legended promptly after the execution and delivery of this Agreement:

     The shares of stock represented by this certificate are subject to the
     terms and provisions of a Voting Agreement among the Corporation and
     certain stockholders of the Corporation.  The Corporation will furnish a
     copy of the Voting Agreement to the holder hereof upon written request and
     without charge.

                                     * * *

     IN WITNESS WHEREOF, the parties have executed this Voting Agreement as a
contract under seal as of the date first written above.

<PAGE>

                          STOCK RESTRICTION AGREEMENT

     This Stock Restriction Agreement made as of May ___, 1997 by and among
Sequenom, Inc., a Delaware corporation (the "Corporation"); Hubert Koster
("Koster"), Nola E. Masterson ("Masterson") and Robert E. Patterson
("Patterson," and together with Koster and Masterson, the "Founders"); the
holders (the "Series B Investors") of shares of the Corporation's Series B
Convertible Preferred Stock, $.001 par value per share (the "Series B Preferred
Stock"); and the purchasers of shares of the Corporation's Series C Convertible
Preferred Stock, par value $.001 per share ("Series C Preferred Stock"),
pursuant to the Series C Convertible Preferred Stock Purchase Agreement dated as
of the date hereof (the "Purchase Agreement"), including any Additional
Investors as defined in the Purchase Agreement (such purchasers being
hereinafter referred to as the "Series C Investors", and, together with the
Series B Investors, the "Investors").

                                WITNESSETH THAT

     WHEREAS, the Series C Investors wish to purchase from the Corporation
certain shares of Series C Preferred Stock and certain warrants to purchase
shares of Series C Preferred Stock;

     WHEREAS, the Series C Investors' purchase of such Series C Preferred Stock
and warrants would materially benefit the Founders and the Series B Investors as
holders of certain shares of the Corporation's capital stock and rights to
acquire such capital stock;

     WHEREAS, it is a condition to the obligations of the Series C Investors
under the Purchase Agreement that this Agreement be executed by the Corporation,
the Founders and the Series B Investors, and the Corporation, the Founders and
the Series B Investors are willing to execute this Agreement and to be bound by
the provisions hereof;

     NOW, THEREFORE, in consideration of the foregoing, the agreements set forth
below, and the parties' desire to provide for continuity of ownership of the
Corporation to further the interests of the Corporation and its present and
future stockholders, the parties hereby agree with each other as follows:

     1.   Certain Defined Terms. As used in this Agreement, the following terms
          ---------------------
shall have the following respective meanings:

     (a) "Common Stock" means the Corporation's Common Stock, $.001 par value
per share.

     (b) "Convertible Securities" means any evidences of indebtedness, shares of
capital stock or other securities directly or indirectly convertible into or
exchangeable for Common Stock.

     (c) "Options" means any rights, options, or warrants to subscribe for,
purchase or otherwise acquire Common Stock or Convertible Securities.

     (d) "Series A Preferred Stock" means the Corporation's Series A Convertible
Preferred Stock, $.001 par value per share.
<PAGE>

     (e) "Shares" shall mean and include all shares of Stock now owned or
hereafter acquired by any Founder or any Investor.

     (f) "Stock" shall mean and include all shares of Common Stock, all
Convertible Securities, all Options, and all other securities of the Corporation
which may be issued in exchange for or in respect of shares of Common Stock,
Convertible Securities or Options (whether by way of stock split, stock
dividend, combination of shares, reclassification, recapitalization,
reorganization, or any other means).

     2.   Prohibited Transfers. None of the Founders shall sell or otherwise
          --------------------
transfer, by gift or otherwise, all or any part of his Shares except in
compliance with the terms of this Agreement.

     3.   Offer of Sale; Notice of Proposed Sale or Transfer. If any Founder
          --------------------------------------------------
desires to sell or otherwise transfer any of his Shares, or of any interest
therein, whether voluntarily or by operation of law, in any transaction other
than pursuant to clauses (iii) or (iv) of Section 7(a) of this Agreement, such
Founder (the "Selling Founder") shall first deliver written notice of his desire
to do so (the "Notice") to the Corporation and each of the Investors. The Notice
must specify: (i) the name and address of the party to which the Selling Founder
proposes to sell or otherwise transfer the Shares or an interest in the Shares
(the "Proposed Transferee"), (ii) the number of Shares the Selling Founder
proposes to sell or otherwise transfer (the "Offered Shares"), (iii) the
consideration per Share to be delivered to the Selling Founder for the proposed
sale or transfer, and (iv) all other material terms and conditions of the
proposed transaction, which must be bona fide.

     4.   Corporation's Option to Purchase.
          --------------------------------

     (a) Except as set forth in Section 7(a), the Corporation shall have the
first option to purchase all or any part of the Offered Shares for the
consideration per Share and on the terms and conditions specified in the Notice.
The Corporation must exercise such option, no later than fifteen (15) business
days after such Notice is deemed to have been delivered to it, by written notice
to the Selling Founder.

     (b) In the event the Corporation does not exercise its option within such
fifteen-business-day period with respect to all of the Offered Shares, the Chief
Financial Officer of the Corporation shall, by the last day of such period, give
written notice of that fact to the Investors (the "Investor Notice").  The
Investor Notice shall specify the number of Offered Shares the Corporation has
elected not to purchase (the "Remaining Shares").

     (c) In the event the Corporation duly exercises its option to purchase all
or a portion of the Offered Shares, the closing of such purchase shall take
place at the offices of the Corporation on the later of (i) the date five
business days after the expiration of such fifteen-business-day period or (ii)
the date that the Investors consummate their purchase of Offered Shares under
Section 5(c) hereof.

     (d) To the extent that the consideration proposed to be paid by the
Proposed Transferee for the Offered Shares consists of property other than cash
or a promissory note, the consideration required to be paid by the Corporation
and/or the Investors exercising their options

                                       2
<PAGE>

under Sections 4 and 5 hereof, respectively, may consist of cash equal to the
value of such property, as determined in good faith by agreement of the Selling
Founder and the Corporation and/or the Investors acquiring such Offered Shares.

     5.   Investors' Option to Purchase and Right to Participate in Sales.
          ---------------------------------------------------------------

          (a) Except as set forth in Section 7(a), each Investor shall have an
option, exercisable for a period of fifteen (15) business days from the date of
delivery of the Investor Notice, to purchase, on a pro rata basis, its
Proportionate Percentage (as defined below) of the Remaining Shares, for the
consideration per Share and on the terms and conditions set forth in the Notice.
Such option shall be exercised by delivery of written notice to the Chief
Financial Officer of the Corporation.  Alternatively, each Investor may, within
the same fifteen-business-day period, notify the Chief Financial Officer of the
Corporation of its desire to participate in the sale of Shares and to sell, on
the terms as set forth in the Notice including at the same price per Share on a
common equivalent basis, up to an equivalent proportion of the Series B
Preferred Stock and Series C Preferred Stock owned by such Investor as the
proposed sale of the Remaining Shares represents with respect to the Shares then
owned by the Selling Founder.

          (b) In the event options to purchase have been exercised by the
Investors with respect to some but not all of the Remaining Shares, the Chief
Financial Officer of the Corporation shall promptly give written notice of that
fact to those Investors who have exercised their options within such period (the
"Second Investor Notice").  The Second Investor Notice shall specify the number
of Remaining Shares the Investors have not elected to purchase.  The Investors
who have exercised their options within the fifteen-business-day period
specified in Section 5(a) shall have an additional option, for a period of ten
(10) business days after delivery of the Second Investor Notice, to purchase all
or any part of the balance of such Remaining Shares on the terms and conditions
set forth in the Notice, which option shall be exercised by the delivery of
written notice to the Chief Financial Officer of the Corporation.  In the event
that there are two or more such Investors that choose to exercise the last-
mentioned option for a total number of Remaining Shares in excess of the number
available, the Remaining Shares available for each such Investor's option shall
be allocated to such Investors pro rata based on their respective Proportionate
Percentages (as defined below).

          (c) Promptly after the expiration of the last period for exercise of
an Investor's purchase option, the Chief Financial Officer of the Corporation
shall give written notice to the Selling Founder and the purchasing Investors,
specifying the number of Remaining Shares to be purchased by each purchasing
Investor.  The closing of the purchase of the Remaining Shares shall take place
at the offices of the Corporation no later than five (5) business days after
delivery of such notice to the Selling Founder and the purchasing Investors.

          (d) As used in this Section 5, the term "Proportionate Percentage"
shall mean with respect to each Investor a fraction, the numerator of which
shall be the amount of Series B Preferred Stock and Series C Preferred Stock
owned by such Investor, and the denominator of which shall be the total amount
of Series B Preferred Stock and Series C Preferred Stock owned by all Investors,
in each case on a common equivalent basis.

                                       3
<PAGE>

     6.   Co-Sale.
          -------

          (a) If the Corporation and the Investors do not exercise their options
to purchase all of the Offered Shares within the periods described in this
Agreement (the "Option Period"), then each Investor which has, pursuant to
Section 5(a), expressed a desire to sell shares of Series B Preferred Stock and
Series C Preferred Stock in the transaction (a "Participating Investor") shall
be entitled to do so pursuant to this Section.  The Chief Financial Officer of
the Corporation shall promptly, on expiration of the Option Period, notify the
Selling Founder of the aggregate amount of Series B Preferred Stock and Series C
Preferred Stock the Participating Investors wish to sell.  The Selling Founder
shall use his best efforts to interest the Proposed Transferee in purchasing, in
addition to the Remaining Shares not subscribed for by the Investors, the Series
B Preferred Stock and Series C Preferred Stock the Participating Investors wish
to sell.  If the Proposed Transferee does not wish to purchase all of the Stock
so made available by the Selling Founder and the Participating Investors, then
each Participating Investor and the Selling Founder shall be entitled to sell,
on the terms and conditions set forth in the Notice and on the same price per
share on a common equivalent basis, a portion of the Stock being sold to the
Proposed Transferee, in the same proportion as such Selling Founder or
Participating Investor's ownership of Stock on a common equivalent basis bears
to the aggregate amount of Stock owned by the Selling Founder and the
Participating Investors on a common equivalent basis.  The transaction
contemplated by the Notice shall be consummated not later than 60 days after the
expiration of the Option Period.

          (b) If the Participating Investors do not elect to sell the full
amount of Series B Preferred Stock and Series C Preferred Stock which they are
entitled to sell pursuant to Section 6(a), the Selling Founder shall be entitled
to sell to the Proposed Transferee, according to the terms set forth in the
Notice, that number of his Shares which equals the difference between the amount
of Stock desired to be purchased by the Proposed Transferee and the number of
shares of Series B Preferred Stock and Series C Preferred Stock the
Participating Investors wish to sell, in each case on a common equivalent basis.

          (c) If the Selling Founder wishes to sell or otherwise transfer any of
his Shares at a price per Share which differs from that set forth in the Notice,
upon terms different from those previously offered to the Corporation and the
Investors, or more than 60 days after the expiration of the Option Period, then,
as a condition precedent to such transaction, such Shares must first be offered
to the Corporation and the Investors on the same terms and conditions as given
the Proposed Transferee, and the Investors must first be offered the opportunity
to participate in such transaction, in accordance with the procedures and time
periods set forth above.

     7.   Permitted Transfers.
          -------------------

          (a) Subject to the provisions of Section 7(b) and Section 8, the
Corporation's and the Investors' right of first refusal and the Investors' right
of co-sale described in Sections 4 through 6 shall not apply to: (i) any
transfer of Shares by a Founder by gift or bequest or through inheritance to, or
for the benefit of, any member or members of such Founder's immediate family;
(ii) any transfer of Shares by an Founder to a trust (A) in respect of which
such Founder serves as trustee, provided that the trust instrument governing
such trust shall provide that such

                                       4
<PAGE>

Founder, as trustee, shall retain sole and exclusive control over the voting and
disposition of such Shares until the termination of this Agreement or (B) for
the benefit solely of any member or members of such Founder's immediate family;
(iii) any sale or transfer of Shares to the Corporation; (iv) any underwritten
public offering of Common Stock pursuant to an effective registration statement
under the Securities Act of 1933, as amended (the "Securities Act"); and (v)
with respect to sales or other transfers of up to an aggregate of the following
number of Shares (as adjusted to reflect any stock split, stock dividend,
combination of shares or other similar transaction), but subject in any case to
the restrictions set forth in Section 8: (A) in the case of each of Koster and
Masterson, 130,000 Shares; and (B) in the case of Patterson, 50,000 Shares;

          (b) In the event of any sale or transfer described in clauses (i) or
(ii) of Section 7(a), the transferee of the Shares shall hold the Shares so
acquired subject to all the restrictions imposed by this Agreement and shall be
deemed a Founder for all purposes hereof, and as a condition to such transfer,
any such transferee shall, at the request of the Corporation or any Investor,
execute and deliver a written instrument agreeing to be bound by the provisions
of this Agreement.

     8.   Consent of the Corporation to Transfer. As a condition to selling or
          --------------------------------------
otherwise transferring any Shares proposed to be sold or transferred by the
Selling Founder and any Participating Investor to any Proposed Transferee, other
than a sale or transfer described in clause (iii) or (iv) of Section 7(a), the
Selling Founder shall have obtained the written consent to such transfer by the
Board of Directors of the Corporation by majority vote at a meeting or by
unanimous consent in lieu of a meeting. Such consent shall not be unreasonably
withheld, and shall be based on the Board of Directors' determination, after
such inquiry as it deems appropriate, but within thirty days of the date of the
Selling Founder's notice to the Corporation under Section 3, that the Proposed
Transferee is not a competitor of the Corporation and is not otherwise an
inappropriate investor in the Corporation. In the event the Selling Founder
disagrees with such determination, and the Board of Directors and the Selling
Founder are unable to resolve the disagreement, an independent third party
selected and agreed upon by the Board of Directors and the Selling Founder shall
arbitrate and finally resolve the disagreement.

     9.   Lock-up. Each Founder agrees that upon the request of the Corporation
          -------
or the underwriters managing an underwritten offering of the Corporation's
securities, such Founder will not sell, make any short sale or loan of, grant
any option for the purchase of, or otherwise dispose of any Shares held by him
without the prior written consent of the Corporation or such underwriters, as
the case may be, for a period of up to 180 days from effective date of the
applicable registration statement.

     10.  Sale or Transfer in Violation of this Agreement. If any sale or other
          -----------------------------------------------
transfer of Shares is made or attempted in violation of any provision of this
Agreement, or if any Shares are not offered to the Corporation or the Investors
as required hereby, the Corporation and the Investors, as the case may be, shall
have the right to purchase such Shares from the owner thereof or his transferee
at any time before or after the transfer, as herein provided. In addition to any
other legal or equitable remedies which it or they may have, the Corporation and
the Investors may enforce their respective rights hereunder by actions for
specific performance (to the extent permitted by law). The Corporation shall not
be required (i) to transfer on its books

                                       5
<PAGE>

any Shares or other Stock which has been sold or transferred in violation of any
provision of this Agreement or (ii) to treat as the owner of such Shares or
Stock, or to pay dividends to, any transferee to whom any such Shares or Stock
have been so sold or transferred. If a Founder becomes obligated to sell any
Shares to the Corporation under this Agreement and fails to deliver such Shares
in accordance with the terms of this Agreement, the Corporation may, at its
option, in addition to all other remedies it may have, send to such Founder the
purchase price for such Shares as is herein specified and cancel on its books
the certificate or certificates representing the Shares to be sold. Thereafter,
all of the Founder's rights in and to such Shares shall terminate.

     11.  Disposition of Shares. Any Shares that the Corporation elects to
          ---------------------
purchase hereunder may be disposed of by it in such manner as it deems
appropriate with or without restrictions on the transfer thereof, and the
Corporation may require their transfer to a nominee or designee as part of any
purchase of the Shares from the Founders.

     12.  Restrictive Legend. All certificates representing Shares held by the
          ------------------
Founders which are subject to this Agreement shall have affixed thereto a legend
in substantially the following form, in addition to any other legends that may
be required by the Corporation in connection with compliance with federal or
state securities laws or otherwise:

          "The shares of stock represented by this certificate are subject to
          restrictions on transfer and/or an option to purchase set forth in a
          Stock Restriction Agreement between the Corporation and the registered
          owner of the shares represented by this certificate (or his
          predecessor in interest).  The Corporation will furnish a copy of such
          agreement to the holder of this certificate upon written request
          without charge."

The Founders shall cause such legend to be affixed to any of such certificates
not so legended.

     13.  Term. This Agreement shall terminate upon the closing of a fm
          ----
commitment underwritten public offering of Common Stock pursuant to an effective
registration statement under the Securities Act in which (i) the public offering
price per share is not less than $9.45 (appropriately adjusted to take account
of any stock split, stock dividend, combination of shares or similar event) and
(ii) the aggregate gross proceeds to the Corporation are not less than
$20,000,000.

     14.  Specific Enforcement. Each Founder expressly agrees that a violation
          --------------------
of this Agreement by such Founder could not be adequately compensated by money
damages alone and that the Investors and the Corporation will be irreparably
damaged if this Agreement is not specifically enforced. Upon a breach or
threatened breach of the terms, covenants and/or conditions of this Agreement by
any Founder, the Investors and the Corporation shall, in addition to all other
remedies, each be entitled to a temporary or permanent injunction, and/or a
decree for specific performance, in accordance with the provisions hereof.

     15.  Other Agreements. The restrictions on the Founders' right to dispose
          ----------------
of their Shares pursuant to this Agreement are in addition to and to be
construed consistently with the Founders' rights and obligations (including
restrictions on the Founders' right to dispose of

                                       6
<PAGE>

shares of the Corporation's capital stock) contained in any other agreement
relating to restrictions on the transferability of such Shares that the Founders
execute before, on, or after the date hereof; provided, that this Agreement
shall supersede and replace the Stock Restriction Agreement dated as of December
22, 1995 among the Corporation, the Founders and the Series B Investors, which
shall no longer be of any force or effect.

     16.  Waiver, Modification and Termination. No provision of this Agreement
          ------------------------------------
shall be deemed to have been waived by the Corporation or any Investor in the
absence of a written agreement executed by such party with respect to such
waiver. This Agreement may be modified or terminated only with the written
consent of the Founders, the Corporation, and the holders of a majority in
voting power of the Shares then held by the Investors.

     17.  Accession. Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     18.  Binding Effect; Assignment. This Agreement shall be binding upon the
          --------------------------
parties hereto and their heirs, legal representatives, successors and assigns.
The rights and obligations of the Founders hereunder may not be assigned or
delegated without the written consent of the Corporation.

     19.  Notices. All notices, requests, consents, deliveries and other
          -------
communications hereunder shall be in writing and shall be delivered in person or
duly sent by first class mail postage prepaid (other than in the case of non-
U.S. parties) or by fax or DHL, Federal Express or other internationally
recognized express courier service, to the Corporation at its principal place of
business, and to the Investors and the Founders at their respective last known
address or at their respective address, if any, appearing on the books of the
Corporation.

     20.  Severability. If any provision of this Agreement shall be held to be
          ------------
illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

     21.  Governing Law. This Agreement shall be governed by, and construed and
          -------------
enforced in accordance with, the substantive law of The Commonwealth of
Massachusetts, without regard to its principles of conflicts of laws.

     22.  Captions. Captions are for convenience only and are not deemed to be
          --------
part of this Agreement.

     23.  Counterparts. This Agreement may be executed in one or more
          ------------

any Shares or other Stock which has been sold or transferred in violation of any
provision of this Agreement or (ii) to treat as the owner of such Shares or
Stock, or to pay dividends to, any transferee to whom any such Shares or Stock
have been so sold or transferred. If a Founder becomes obligated to sell any
Shares to the Corporation under this Agreement and fails to deliver such Shares
in accordance with the terms of this Agreement, the Corporation may, at its
option, in addition to all other remedies it may have, send to such Founder the
purchase price for such Shares as is herein specified and cancel on its books
the certificate or certificates representing the Shares to be sold. Thereafter,
all of the Founder's rights in and to such Shares shall terminate.

     11.  Disposition of Shares. Any Shares that the Corporation elects to
          ---------------------
purchase hereunder may be disposed of by it in such manner as it deems
appropriate with or without restrictions on the transfer thereof, and the
Corporation may require their transfer to a nominee or designee as part of any
purchase of the Shares from the Founders.

     12.  Restrictive Legend. All certificates representing Shares held by the
          ------------------
Founders which are subject to this Agreement shall have affixed thereto a legend
in substantially the following form, in addition to any other legends that may
be required by the Corporation in connection with compliance with federal or
state securities laws or otherwise:

          "The shares of stock represented by this certificate are subject to
          restrictions on transfer and/or an option to purchase set forth in a
          Stock Restriction Agreement between the Corporation and the registered
          owner of the shares represented by this certificate (or his
          predecessor in interest).  The Corporation will furnish a copy of such
          agreement to the holder of this certificate upon written request
          without charge."

The Founders shall cause such legend to be affixed to any of such certificates
not so legended.

     13.  Term. This Agreement shall terminate upon the closing of a fm
          ----

(ii) the aggregate gross proceeds to the Corporation are not less than
$20,000,000.

     14.  Specific Enforcement. Each Founder expressly agrees that a violation
          --------------------
of this Agreement by such Founder could not be adequately compensated by money
damages alone and that the Investors and the Corporation will be irreparably
damaged if this Agreement is not specifically enforced. Upon a breach or
threatened breach of the terms, covenants and/or conditions of this Agreement by
any Founder, the Investors and the Corporation shall, in addition to all other
remedies, each be entitled to a temporary or permanent injunction, and/or a
decree for specific performance, in accordance with the provisions hereof.

     15.  Other Agreements. The restrictions on the Founders' right to dispose
          ----------------
of their Shares pursuant to this Agreement are in addition to and to be
construed consistently with the Founders' rights and obligations (including
restrictions on the Founders' right to dispose of

                                       6

shares of the Corporation's capital stock) contained in any other agreement
relating to restrictions on the transferability of such Shares that the Founders
execute before, on, or after the date hereof; provided, that this Agreement
shall supersede and replace the Stock Restriction Agreement dated as of December
22, 1995 among the Corporation, the Founders and the Series B Investors, which
shall no longer be of any force or effect.

     16.  Waiver, Modification and Termination. No provision of this Agreement
          ------------------------------------
shall be deemed to have been waived by the Corporation or any Investor in the
absence of a written agreement executed by such party with respect to such
waiver. This Agreement may be modified or terminated only with the written
consent of the Founders, the Corporation, and the holders of a majority in
voting power of the Shares then held by the Investors.

     17.  Accession. Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     18.  Binding Effect; Assignment. This Agreement shall be binding upon the
          --------------------------
parties hereto and their heirs, legal representatives, successors and assigns.
The rights and obligations of the Founders hereunder may not be assigned or
delegated without the written consent of the Corporation.

     19.  Notices. All notices, requests, consents, deliveries and other
          -------

recognized express courier service, to the Corporation at its principal place of
business, and to the Investors and the Founders at their respective last known
address or at their respective address, if any, appearing on the books of the
Corporation.

     20.  Severability. If any provision of this Agreement shall be held to be
          ------------
illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

     21.  Governing Law. This Agreement shall be governed by, and construed and
          -------------
enforced in accordance with, the substantive law of The Commonwealth of
Massachusetts, without regard to its principles of conflicts of laws.

     22.  Captions. Captions are for convenience only and are not deemed to be
          --------
part of this Agreement.

     23.  Counterparts. This Agreement may be executed in one or more

Description of the grant programs for which Sequenom Instruments GmbH has
received approvals:

1.   Grant from the "Biotechnology 2000" grant scheme from the Ministry of
Research and Technology ("BMBF"):

     The BMBF has approved a grant (which is a non-repayable contribution) in
the amount of DM 2.2 million based on the application for the financing of a
total research and development project of DM 4.4 million.  The grant coverage is
therefore 50% of total estimated project cost.  The company will call the money
quarterly in arrears based on actual cost attributable to the project.  The
project started on September 1, 1995 and has a duration of three years.

2.   Grant from Freie und Hansestadt Hamburg (City of Hamburg):

     The City of Hamburg has approved a grant of DM 800,000 based on a list of
equipment for Sequenom's laboratory to be purchased after September 1, 1995.
Total expected cash outflows for the equipment purchases is DM 1.6 million.
Grant coverage is also 50% of estimated cost.

Both grants do not have to be repaid.

To the Persons listed in the Schedule of
 Investors to the Series C Convertible
 Preferred Stock Purchase Agreement
 dated as of May 8, 1997

Ladies/Gentlemen:

     We are counsel to Sequenom, Inc., a Delaware corporation (the
"Corporation").  This opinion is rendered to you pursuant to Section 6.5 of the
Series C Convertible Preferred Stock Purchase Agreement (including the exhibits
thereto, the "Agreement') dated as of May 8, 1997, among the Corporation and
each of you relating to the issuance and sale by the Corporation to you of up to
an aggregate of 1,904,770 shares (the "Shares") of its Series C Convertible
Preferred Stock, par value $.001 per share ("Series C Preferred"), and warrants
to purchase up to an aggregate of 190,477 shares of Series C Preferred (the
"Warrants") (the "Transaction").  Capitalized terms used herein and not
otherwise defined herein shall have the meanings assigned to such terms in the
Agreement.

     In connection with our rendering this opinion, we have reviewed (i) the
Certificate of Incorporation and By-Laws of the Corporation, each as amended to
date; (ii) a certificate issued by the Secretary of State of the State of
Delaware on May 2, 1997, with respect to the due incorporation, legal existence
and good standing of the Corporation in the State of Delaware (the "Legal
Existence Certificate"); (iii) counterparts of the Agreement and the related
Registration Rights Agreement dated May 8, 1997 (the "Registration Rights
Agreement'); and (iv) originals or copies, certified or otherwise, identified to
our satisfaction, of such other documents, certificates, instruments and
corporate records that we considered necessary for the purposes of this opinion.

     In rendering the opinion expressed herein, we have also examined and have
relied completely as to matters of fact upon the representations and warranties
made by the Corporation and each of you in the Agreement, the Registration
Rights Agreement and the other agreements, instruments and documents delivered
in connection with the Initial Closing on the date hereof; and we have assumed
the completeness and accuracy of all factual matters described in such
representations and warranties.

To the Persons listed in the Schedule of
 Investors to the Series C Convertible
 Preferred Stock Purchase Agreement
 dated as of May 8, 1997


     We have not, except as specifically noted above, made any independent
review or investigation of facts relating to the Corporation, including but
without limiting the generality of the foregoing, any investigation as to the
existence of any actions, suits or proceedings pending or threatened against the
Corporation or notes, indentures, mortgages, leases, contracts, instruments,
documents, agreements, judgments, injunctions, orders, writs or decrees to which
the Corporation is a party, which are binding upon the Corporation or which
might result in the imposition of any lien or other encumbrance on any asset of
the Corporation.

     We have assumed the authenticity and completeness of all documents
furnished to us as originals, the genuineness of all signatures, the legal
capacity of natural persons, and the conformity to the originals of all
documents furnished to us as copies.

     In rendering the opinions expressed in paragraph 1 below with respect to
the due incorporation, legal existence and good standing of the Corporation in
Delaware, we have relied solely on the Legal Existence Certificate.

     You have not asked us to pass upon your power and authority to enter into
the Agreement or the Registration Rights Agreement.  Accordingly, for the
purposes of this opinion, we have assumed that you have all requisite power and
authority to enter into the Agreement and the Registration Rights Agreement and
to effect the transactions contemplated thereby, and that each of the Agreement
and the Registration Rights Agreement constitutes the valid and legally binding
obligation of all parties thereto other than the Corporation.

     We have made such examination of Massachusetts and federal Law and of the
General Corporation Law of Delaware as we deem necessary for the purposes of
this opinion.  We do not purport to pass herein on the laws of any state or
jurisdiction other than the United States of America and the Commonwealth of
Massachusetts, and as to its General Corporation Law only, the State of
Delaware.

     The opinions herein expressed are qualified to the extent that (i) the
validity or enforceability of any provisions of any agreement or instrument or
of any rights granted thereunder may be subject to or affected by any
bankruptcy, reorganization, insolvency, moratorium or similar law from time to
time in effect and relating to or affecting the rights or remedies of creditors
generally, (ii) the remedy of specific performance or any other equitable remedy
may be unavailable in any jurisdiction or may be withheld as a matter of
judicial discretion; and (iii) a court may apply equitable principles in
construing or enforcing the provisions of any agreement or instrument.

     The phrase "of which we have knowledge" means the actual knowledge of the
lawyer signing this opinion letter and the other lawyers in our office who have
had active involvement in negotiating the Transaction and preparing the
Agreement and the Registration Rights Agreement.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.   The Corporation is a corporation duly incorporated, validly existing
          and in good standing under the laws of the State of Delaware and has

          currently being conducted.

     2.   The execution and delivery of the Agreement and the Registration
          Rights Agreement and the performance by the Corporation of its
          obligations thereunder have been duly authorized by all necessary
          corporate action on the part of the Corporation and do not violate or
          cause any default under any provision of (i) the Corporation's
          Certificate of Incorporation or By-Laws, or (ii) except where any such
          violation or default would not have a material adverse effect on the
          Corporation, any note, indenture, mortgage, lease, contract or other
          instrument, document or agreement to which the Corporation is a party
          and of which we have knowledge or any writ, injunction, order,
          judgment or decree of any court, administrative agency or other
          governmental body to which the Company is a party and of which we have
          knowledge.  Each of the Agreement and the Registration Rights
          Agreement constitutes a valid and legally binding obligation of the
          Corporation, enforceable against the Corporation in accordance with
          its terms; provided, however, that we express no opinion as to the
          enforceability of the indemnification provisions contained in Section
          10 of the Registration Rights Agreement.

     3.   The sale of Shares and the Warrants to each of you is not required to
          be registered under the Securities Act of 1933 or the Massachusetts
          Uniform Securities Act.

     4.   Upon receipt by the Corporation of the purchase price therefor, the
          Shares will be validly issued, fully-paid and non-assessable.

     5.   No authorization, consent, approval or other order of, declaration to,
          or filing with, any United States or Massachusetts governmental agency
          or body is required to be made or obtained by the Corporation for or
          in connection with the valid and lawful authorization, execution and
          delivery by the Corporation of the Agreement and the Registration
          Rights Agreement, for or in connection with the valid and lawful
          authorization, issuance, sale and delivery of the Shares and the
          Warrants or for or in connection with the valid and lawful
          authorization, reservation, issuance, sale and delivery of the
          Reserved Shares to be issued upon the conversion of the Shares, except
          such exemptive filings, if any, as are required to be made under
          applicable securities laws.


                                    Very truly yours,

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

    8.1   Right of First Refusal.
          ----------------------

          (a)  Subject to the limitations set forth in paragraph (i) of this
Section 8.1 and in Section 8.9, the Corporation hereby grants to each Investor,
each Series C Investor, each Series B Investor, each Founder, and any of their
respective permitted assignees described in paragraph (j) of this Section 8.1
(each a "Right Holder") the right of first refusal to purchase, pro rata, all
(or any part) of any New Securities (as defined in this Section 8.1(b)) that the
Corporation may, from time to time, propose to sell or issue. Each such Right
Holder's pro rata share, for purposes of this right of first refusal, is the
ratio of (i) the number of shares of Common Stock then held of record by, or
issuable on conversion of Series D Preferred, Series C Preferred, Series B
Preferred or Series A Preferred (collectively, "Preferred Stock") then held of
record by, such Right Holder to (ii) the sum of the total number of shares of
the Common Stock issued and outstanding plus the total number of shares of
Common Stock issuable upon conversion of the Preferred Stock, in each case at
such time (the "Basic Amount").

          (b)  "New Securities" shall mean any equity securities of the
Corporation, whether now authorized or not, and rights, options, or warrants to
purchase said equity securities, and securities of any type whatsoever that are,
or may become, convertible into said equity securities; provided, however, that
"New Securities" does not include (i) securities offered to the public pursuant
to a registration statement filed under the Securities Act, the gross proceeds
to the Corporation from the sale of which would equal or exceed $20,000,000;
(ii) securities issued pursuant to the acquisition of another corporation by the
Corporation by merger, purchase of substantially all of the assets, or other
reorganization whereby the Corporation acquires not less than a majority of the
voting power of such corporation; (iii) up to 2,700,000 shares (appropriately
adjusted to take account of any stock split, stock dividend, combination of
shares or the like) of Common Stock (or related options) issued to employees,
officers or other persons performing services for the Corporation pursuant to
any stock offering, plan or arrangement approved by the Board of Directors of
the Corporation, which number may be adjusted upward by the affirmative vote of
a majority of the whole Board of Directors; (iv) securities issued in connection
with any stock split, stock dividend or recapitalization by the Corporation; (v)
shares of Common Stock issued upon conversion of the Shares; (vi) securities
issuable upon exercise or

                                       13
<PAGE>

conversion of any rights, options, warrants or convertible securities
outstanding on the date of this Agreement; (vii) securities issued to any
financial institution in connection with a loan transaction approved by the
Board of Directors of the Corporation; (viii) securities issued to vendors or
customers or to other persons in similar commercial situations with the
Corporation, provided such issuance is approved by the Board of Directors of the
Corporation; (ix) securities issued in connection with obtaining lease
financing, whether issued to a lessor, guarantor or other person involved in the
financing, provided such issuance is approved by the Board of Directors of the
Corporation; (x) the Additional Shares; (xi) securities issued to Technologie-
Beteiligungs-Gesellschaft mbH der Deutschen Ausgleighsbank ("TBG") upon
conversion of any repayment premiums payable to TBG by the Corporation's German
subsidiary pursuant to silent partnership arrangements in the aggregate amount
of DM 6 million; or (xii) any right, option or warrant to acquire any security
convertible into securities excluded from the definition of New Securities
pursuant to clauses (i) through (x) above.

          (c)  The Corporation shall not issue, sell or exchange, agree to
issue, sell or exchange, or reserve or set aside for issuance, sale or exchange
any New Securities unless the Corporation shall deliver to each Right Holder a
written notice of any proposed or intended issuance, sale or exchange of New
Securities (the "Offer"), which Offer shall (i) identify and describe the New
Securities, (ii) describe the price and other terms upon which they are to be
issued, sold or exchanged, and the number or amount of the New Securities to be
issued, sold or exchanged, (iii) identify the persons or entities to which or
with which the New Securities are to be offered, issued, sold or exchanged and
(iv) offer to issue and sell to or exchange with such Right Holder (a) such
Right Holder's Basic Amount, and (b) any additional portion of the New
Securities as such Right Holder shall indicate it will purchase or acquire
should the other Right Holders subscribe for less than their Basic Amounts (the
"Undersubscription Amount"). Each Right Holder shall have the right, for a
period of 30 days following delivery of the Offer, to purchase or acquire, at a
price and upon the other terms specified in the Offer, the number or amount of
New Securities described above. The Offer by its terms shall remain open and
irrevocable for such 30-day period.

          (d)  To accept an Offer, in whole or in part, a Right Holder must
deliver a written notice to the Corporation prior to the end of the 30-day
period of the Offer, setting forth the portion of the Right Holder's Basic
Amount that such Right Holder elects to purchase and, if such Right Holder shall
elect to purchase all of its Basic Amount, the Undersubscription Amount (if any)
that such Right Holder elects to purchase (the "Notice of Acceptance"). If the
Basic Amounts subscribed for by all Right Holders are less than the total New
Securities, then each Right Holder who has set forth an Undersubscription Amount
in its Notice of Acceptance shall be entitled to purchase, in addition to the
Basic Amount subscribed for, the Undersubscription Amount it has subscribed for;
provided, however, that should the Undersubscription Amounts subscribed for
exceed the difference between the New Securities and the Basic Amounts
subscribed for (the "Available Undersubscription Amount"), each Right Holder who
has subscribed for any Undersubscription Amount shall be entitled to purchase
only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Right Holder bears to the total
Undersubscription Amounts subscribed for by all Right Holders, subject to
rounding by the Board of Directors to the extent it reasonably deems necessary.

                                       14
<PAGE>

          (e)  In the event that Notices of Acceptance are not given by the
Right Holders in respect of all the New Securities, the Corporation shall have
90 days from the expiration of the period set forth in paragraph (c) above to
issue, sell or exchange all or any part of such New Securities as to which a
Notice of Acceptance has not been given by the Right Holders (the "Refused
Securities"), but only to the offerees or purchasers and only upon terms and
conditions (including, without limitation, unit prices and interest rates) which
are described in the Offer.

          (f)  In the event the Corporation shall propose to sell less than all
the Refused Securities (any such sale to be in the manner and on the terms
specified in paragraph (e) above), then each Right Holder may, at its sole
option and in its sole discretion, reduce the number or amount of the New
Securities specified in its Notice of Acceptance to an amount that shall be not
less than the number or amount of the New Securities that the Right Holder
elected to purchase pursuant to paragraph (d) above multiplied by a fraction,
(i) the numerator of which shall be the number or amount of New Securities the
Corporation actually proposes to issue, sell or exchange (including New
Securities to be issued or sold to Right Holders pursuant to paragraph (d) above
prior to such reduction) and (ii) the denominator of which shall be the amount
of all New Securities. In the event that any Right Holder so elects to reduce
the number or amount of New Securities specified in its Notice of Acceptance,
the Corporation may not issue, sell or exchange more than the reduced number or
amount of the New Securities unless and until such securities have again been
offered to the Right Holders in accordance with paragraph (c) above.

          (g)  Upon the closing of the issuance, sale or exchange of all or less
than all the Refused Securities, the Right Holders shall acquire from the
Corporation, and the Corporation shall issue to the Right Holders, the number or
amount of New Securities specified in the Notices of Acceptance, as reduced
pursuant to paragraph (f) above if the Right Holders have so elected, upon the
terms and conditions specified in the Offer. The purchase by the Right Holders
of any New Securities is subject in all cases to the preparation, execution and
delivery by the Corporation and the Right Holders of a purchase agreement
relating to such New Securities reasonably satisfactory in form and substance to
the Right Holders and their respective counsel.

          (h)  Any New Securities not acquired by the Right Holders or other
persons in accordance with paragraph (e) above may not be issued, sold or
exchanged until they are again offered to the Right Holders under the procedures
specified in this Agreement.

          (i)  This right of first refusal shall run to each Investor, each
Series C Investor, each Series B Investor, each Founder and any of their
respective permitted assignees under paragraph (j) of this Section 8.1 only for
so long as they hold the following number of shares of Common Stock (including
in such number shares of Common Stock issuable upon conversion of Preferred
Stock):

               (i)   in the case of the Founders and the Series B Investors who
were parties to the Stock Purchase Agreement dated May 26, 1994, and their
respective permitted assignees, 50,000 shares; and

                                       15
<PAGE>

               (ii)  in the case of all other Series B Investors, the Series C
Investors and the Investors, and their respective permitted assignees, 200,000
shares (including shares held by their respective Affiliates (as hereinafter
defined)).

          (j)  This right of first refusal may be assigned, in whole or in part,
(i) to any Affiliate (as hereinafter defined) of any Right Holder or (ii) to any
assignee who acquires not less than 50,000 shares of Common Stock in the case of
an assignment from assignor described in clause (i) of paragraph (i) of this
Section 8.1, or 200,000 shares of Common Stock in the case of an assignment from
an assignor described in clause (ii) of paragraph (i) of this Section 8.1 (in
each case, including in such number shares of Common Stock issuable upon
conversion of Preferred Stock and appropriately adjusted to take account of any
stock split, stock dividend, combination of shares, or the like). As used in
this Section, an Affiliate of a Right Holder shall mean any general or limited
partner of the Right Holder that is a partnership or any person or entity that,
directly or indirectly, through one or more intermediaries, controls, or is
controlled by, or is under common control with, the Right Holder. In addition,
for purposes of this Section, in the case of any Right Holder that is a limited
partnership for which TVM Techno Venture Management Limited Partnership, TVM
Techno Venture Management III GmbH or any of their respective Affiliates serves
as a general partner, the term Affiliate of any such Right Holder shall include
KBL Founder Ventures SCA, KB Lux Venture Capital Fund - European Biotechnology
and their respective Affiliates and Alpinvest International B.V. and its
Affiliates.

          (k)  This Section 8.1 shall amend and restate Section 8.1 of the
Series C Purchase Agreement, which Section 8.1 shall no longer have any force or
effect.

    8.2   Keeping of Records and Books of Account.  The Corporation shall keep,
          ---------------------------------------
and cause each subsidiary to keep, adequate records and books of account, in
which complete entries will be made in accordance with generally accepted
accounting principles consistently applied, reflecting all financial

amortization, taxes, bad debts and other purposes in connection with its
business shall be made.

    8.3   Insurance.  The Corporation will do or cause to be done all things
          ---------
necessary to preserve and maintain in full force and effect fire and casualty
insurance policies, with extended coverage, on its properties, assets, business
and personnel, in amounts deemed adequate by the Corporation, and in accordance
with the standards of the industry in which the Corporation operates, sufficient
in amount to allow it to replace any of its properties which might be damaged or
destroyed.

    8.4   Key Man Life Insurance.  The Corporation shall use its best efforts to
          ----------------------
maintain in force a policy of life insurance, naming the Corporation as

the Corporation may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Corporation from

discontinuance is, in the good faith judgment of the Board of Directors of the
Corporation, desirable in the conduct of its business.

all material liabilities of the Corporation; provided, however, that the
Corporation shall not be required to pay or discharge or cause to be paid or

                                SEQUENOM, INC.

     Section 1.    CERTIFICATE OF INCORPORATION AND BYLAWS
     ---------     ---------------------------------------

     1.1  These Bylaws are subject to the certificate of incorporation of the
corporation.  In these bylaws, references to the certificate of incorporation
and bylaws mean the provisions of the certificate of incorporation and the
bylaws as are from time to time in effect.

     Section 2.    OFFICES
     ---------     -------

     2.1  Registered Office.  The registered office shall be in the City of
          -----------------
Wilmington, County of New Castle, State of Delaware.

     2.2  Other Offices.  The corporation may also have offices at such other
          -------------
places both within and without the State of Delaware as the board of directors
may from time to time determine or the business of the corporation may require.

     Section 3.    STOCKHOLDERS
     ---------     ------------

     3.1  Location of Meetings.  All meetings of the stockholders shall be held
          --------------------
at such place either within or without the State of Delaware as shall be
designated from time to time by the board of directors.  Any adjourned session
of any meeting shall be held at the place designated in the vote of adjournment.

     3.2  Annual Meeting.  The annual meeting of stockholders shall be held at
          --------------
10:00 a.m. on the second Wednesday in May in each year, unless that day be a
legal holiday at the place where the meeting is to be held, in which case the
meeting shall be held at the same hour on the next succeeding day not a legal
holiday, or at such other date and time as shall be designated from time to time
by the board of directors, at which they shall elect a board of directors and
transact such other business as may be required by law or these bylaws or as may
properly come before the meeting.

     3.3  Special Meeting in Place of Annual Meeting.  If the election for
          ------------------------------------------
directors shall not be held on the day designated by these bylaws, the directors
shall cause the election to be held as soon thereafter as convenient, and to
that end, if the annual meeting is omitted on the day herein provided therefor
or if the election of directors shall not be held thereat, a special meeting of
the stockholders may be held in place of such omitted meeting or election, and
any business transacted or election held at such special meeting shall have the
same effect as if transacted or held at the annual meeting, and in such case all
references in these bylaws to the annual meeting of the stockholders, or to the
annual election of directors, shall be deemed to refer to or include such
special meeting.  Any such special meeting shall be called and the purposes
thereof shall be specified in the call, as provided in Section 3.4.

     3.4  Notice of Annual Meeting.  Written notice of the annual meeting
          ------------------------
stating the place, date and hour of the meeting shall be given to each
stockholder entitled to vote at such meeting not less than ten nor more than
sixty days before the date of the meeting.  Such notice may
<PAGE>

specify the business to be transacted and actions to be taken at such meeting.
No action shall be taken at such meeting unless such notice is given, or unless
waiver of such notice is given by the holders of outstanding stock having not
less than the minimum number of votes necessary to take such action at a meeting
at which all shares entitled to vote thereon were voted. Prompt notice of all
action taken in connection with such waiver of notice shall be given to all
stockholders not present or represented at such meeting.

     3.5  Other Special Meetings.  Special meetings of the stockholders, for any
          ----------------------
purpose or purposes, unless otherwise prescribed by law or by the certificate of
incorporation, may be called by the president and shall be called by the
president or secretary at the request in writing of a majority of the board of
directors, or at the request in writing of the holders of at least ten percent
of all capital stock of the corporation issued and outstanding and entitled to
vote at such meeting.  Such request shall state the purpose or purposes of the
proposed meeting and business to be transacted at any special meeting of the
stockholders.

     3.6  Notice of Special Meeting.  Written notice of a special meeting
          -------------------------
stating the place, date and hour of the meeting and the purpose or purposes for
which the meeting is called, shall be given not less than ten nor more than
sixty days before the date of the meeting, to each stockholder entitled to vote
at such meeting.  No action shall be taken at such meeting unless such notice is
given, or unless waiver of such notice is given by the holders of outstanding
stock having not less than the minimum number of votes necessary to take such
action at a meeting at which all shares entitled to vote thereon were voted.
Prompt notice of all action taken in connection with such waiver of notice shall
be given to all stockholders not present or represented at such meeting.

     3.7  Stockholder List.  The officer who has charge of the stock ledger of
          ----------------
the corporation shall prepare and make, at least ten days before every meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

     3.8  Quorum of Stockholders.  The holders of a majority of the stock issued
          ----------------------
and outstanding and entitled to vote thereat, present in person or represented
by proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise required by law, or by the
certificate of incorporation or by these bylaws.  Except as otherwise provided
by law, no stockholder present at a meeting may withhold his shares from the
quorum count by declaring his shares absent from the meeting.

     3.9  Adjournment.  Any meeting of stockholders may be adjourned from time
          -----------
to time to any other time and to any other place at which a meeting of
stockholders may be held under these bylaws, which time and place shall be
announced at the meeting, by a majority of votes cast upon the question, whether
or not a quorum is present.  At such adjourned meeting at which a quorum shall
be present or represented any business may be transacted which might have been

                                       2
<PAGE>

transacted at the original meeting.  If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting.

     3.10  Proxy Representation.  Every stockholder may authorize another person
           --------------------
or persons to act for him by proxy in all matters in which a stockholder is
entitled to participate, whether by waiving notice of any meeting, objecting to
or voting or participating at a meeting, or expressing consent or dissent
without a meeting.  Every proxy must be signed by the stockholder or by his
attorney-in-fact.  No proxy shall be voted or acted upon after three years from
its date unless such proxy provides for a longer period.  Except as provided by
law, a revocable proxy shall be deemed revoked if the stockholder is present at
the meeting for which the proxy was given.  A duly executed proxy shall be
irrevocable if it states that it is irrevocable and, if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power.
A proxy may be made irrevocable regardless of whether the interest with which it
is coupled is an interest in the stock itself or an interest in the corporation
generally.  The authorization of a proxy may but need not be limited to
specified action, provided, however, that if a proxy limits its authorization to
a meeting or meetings of stockholders, unless otherwise specifically provided
such proxy  shall entitle the holder thereof to vote at any adjourned session
but shall not be valid after the final adjournment thereof.

     3.11  Inspectors.  The directors or the person presiding at the meeting
           ----------
may, but need not, appoint one or more inspectors of election and any substitute
inspectors to act at the meeting or any adjournment thereof.  Each inspector,
before entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspector at such meeting with strict
impartiality and according to the best of his ability.  The inspectors, if any,
shall determine the number of shares of stock outstanding and the voting power
of each, the shares of stock represented at the meeting, the existence of a
quorum and the validity and effect of proxies, and shall receive votes, ballots
or consents, hear and determine all challenges and questions arising in
connection with the right to vote, count and tabulate all votes, ballots or
consents, determine the result, and do such acts as are proper to conduct the
election or vote with fairness to all stockholders.  On request of the person
presiding at the meeting, the inspectors shall make a report in writing of any
challenge, question or matter determined by them and execute a certificate of
any fact found by them.

     3.12  Action by Vote.  When a quorum is present at any meeting, whether the
           --------------
same be an original or an adjourned session, a plurality of the votes properly
cast for election to any office shall elect to such office and a majority of the
votes properly cast upon any question other than an election to an office shall
decide the question, except when a larger vote is required by law, by the
certificate of incorporation or by these bylaws.  No ballot shall be required
for any election unless requested by a stockholder present or represented at the
meeting and entitled to vote in the election.

     3.13  Action Without Meetings.  Unless otherwise provided in the
           -----------------------
certificate of incorporation, any action required to be taken at any annual or
special meeting of stockholders of the corporation, or any action which may be
taken at any annual or special meeting of such stockholders, may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize

                                       3
<PAGE>

or take such action at a meeting at which all shares entitled to vote thereon
were present and voted. Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.

     Section 4.    DIRECTORS
     ---------     ---------

     4.1  Number.  The number of directors which shall constitute the whole
          ------
board shall not be less than three nor more than seven,  except that whenever
there shall be only one stockholder or prior to issuance of any stock, the
number of directors which shall constitute the whole board shall be not less
than one.  Within the foregoing limits, the stockholders at the annual meeting
shall determine the number of directors, and within such limits, the number of
directors may be increased or decreased at any time or from time to time by the
stockholders or by the directors by vote of a majority of directors then in
office, except that any such decrease by vote of the directors shall only be
made to eliminate vacancies existing by reason of the death, resignation or
removal of one or more directors.  The directors shall be elected at the annual
meeting of the stockholders, except as provided in Section 4.4 of these bylaws.
Directors need not be stockholders.

     4.2  Tenure.  Except as otherwise provided by law, by the certificate of
          ------
incorporation or by these bylaws, each director shall hold office until the next
annual meeting and until his successor is elected and qualified, or until he
sooner dies, resigns, is removed or becomes disqualified.

     4.3  Powers.  The business of the corporation shall be managed by or under
          ------
the direction of the board of directors which shall have and may exercise all
the powers of the corporation and do all such lawful acts and things as are not
by law, the certificate of incorporation or these bylaws directed or required to
be exercised or done by the stockholders.

     4.4  Vacancies.  Vacancies and any newly created directorships resulting
          ---------
from any increase in the number of directors may be filled by vote of the
stockholders at a meeting called for the purpose, or by a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. When one or more directors shall resign from the board, effective at a
future date, a majority of the directors then in office, including those who
have resigned, shall have power to fill such vacancy or vacancies, the vote or
action by writing thereon to take effect when such resignation or resignations
shall become effective.  The directors shall have and may exercise all their
powers notwithstanding the existence of one or more vacancies in their number,
subject to any requirements of law or of the certificate of incorporation or of
these bylaws as to the number of directors required for a quorum or for any vote
or other actions.

     4.5  Committees.  The board of directors may, by vote of a majority of the
          ----------
whole board, (a) designate, change the membership of or terminate the existence
of any committee or committees, each committee to consist of one or more of the
directors; (b) designate one or more directors as alternate members of any such
committee who may replace any absent or disqualified member at any meeting of
the committee; and (c) determine the extent to which each such committee shall
have and may exercise the powers  and authority of the board of directors in the
management of the business and affairs of the corporation, including the power
to authorize the seal of the corporation to be affixed to all papers which
require it and the power and authority to declare dividends or to authorize the
issuance of stock; excepting, however, such

                                       4
<PAGE>

powers which by law, by the certificate of incorporation or by these bylaws they
are prohibited from so delegating. In the absence or disqualification of any
member of such committee and his alternate, if any, the member or members
thereof present at any meeting and not disqualified from voting, whether or not
constituting a quorum, may unanimously appoint another member of the board of
directors to act at the meeting in the place of any such absent or disqualified
member. Except as the board of directors may otherwise determine, any committee
may make rules for the conduct of its business, but unless otherwise provided by
the board or such rules, its business shall be conducted as nearly as may be in
the same manner as is provided by these bylaws for the conduct of business by
the board of directors. Each committee shall keep regular minutes of its
meetings and report the same to the board of directors upon request.

     4.6  Regular Meeting.  Regular meetings of the board of directors may be
          ---------------
held without call or notice at such place within or without the State of
Delaware and at such times as the board may from time to time determine,
provided that notice of the first regular meeting following any such
determination shall be given to absent directors.  A regular meeting of the
directors may be held without call or notice immediately after and at the same
place as the annual meeting of the stockholders.

     4.7  Special Meetings.  Special meetings of the board of directors may be
          ----------------
held at any time and at any place within or without the State of Delaware
designated in the notice of the meeting, when called by the president, or by
one-third or more in number of the directors, reasonable notice thereof being
given to each director by the secretary or by the president or by any one of the
directors calling the meeting.

     4.8  Notice.  It shall be reasonable and sufficient notice to a director to
          ------
send notice by mail at least forty-eight hours or by telegram at least twenty-
four hours before the meeting, addressed to him at his usual or last known
business or residence address or to give notice to him in person or by telephone
at least twenty-four hours before the meeting.  Notice of a meeting need not be
given to any director if a written waiver of notice, executed by him before or
after the meeting, is filed with the records of the meeting, or to any director
who attends the meeting without protesting prior thereto or at its commencement
the lack of notice to him.  Neither notice of a meeting nor a waiver of a notice
need specify the purposes of the meeting.

     4.9  Quorum.  Except as may be otherwise provided by law, by the
          ------
certificate of incorporation or by these bylaws, at any  meeting of the
directors a majority of the directors then in office shall constitute a quorum;
a quorum shall not in any case be less than one-third of the total number of
directors constituting the whole board.  Any meeting may be adjourned from time
to time by a majority of the votes cast upon the question, whether or not a
quorum is present, and the meeting may be held as adjourned without further
notice.

     4.10  Action by Vote.  Except as may be otherwise provided by law, by the
           --------------
certificate of incorporation or by these bylaws, when a quorum is present at any
meeting the vote of a majority of the directors present shall be the act of the
board of directors.

     4.11  Action Without a Meeting.  Unless otherwise restricted by the
           ------------------------
certificate of incorporation or these bylaws, any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting if all the members of the board or of such
committee, as the case may be, consent thereto in writing, and

                                       5
<PAGE>

such writing or writings are filed with the records of the meetings of the board
or of such committee. Such consent shall be treated for all purposes as the act
of the board or of such committee, as the case may be.

     4.12  Participation in Meetings by Conference Telephone. Unless otherwise
           -------------------------------------------------
restricted by the certificate of incorporation or these bylaws, members of the
board of directors or of any committee thereof may participate in a meeting of
such board or committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other.  Such participation shall constitute presence in
person at such meeting.

     4.13  Compensation.  Unless otherwise restricted by the certificate of
           ------------
incorporation or these bylaws, the board of directors shall have the authority
to fix from time to time the compensation of directors.  The directors may be
paid their expenses, if any, of attendance at each meeting of the board of
directors and the performance of their responsibilities as directors and may be
paid a fixed sum for attendance at each meeting of the board of directors and/or
a stated salary as director.  No such payment shall preclude any director from
serving the corporation or its parent or subsidiary corporations in any other
capacity and receiving compensation therefor.  The board of directors may also
allow compensation for members of special or standing committees for service on
such committees.

     4.14  Interested Directors and Officers.
           ---------------------------------

     (a)   No contract or transaction between the corporation and one or more of
its directors or officers, or between the corporation and any other corporation,
partnership, association,  or other organization in which one or more of the
corporation's directors or officers are directors or officers, or have a
financial interest, shall be void or voidable solely for this reason, or solely
because the director or officer is present at or participates in the meeting of
the board or committee thereof which authorizes the contract or transaction, or
solely because his or their votes are counted for such purpose, if:

           (1) The material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the board of directors
or the committee, and the board or committee in good faith authorizes the
contract or transaction by the affirmative votes of a majority of the
disinterested directors, even though the disinterested directors be less than a
quorum; or

           (2) The material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the stockholders
entitled to vote thereon, and the contract or transaction is specifically
approved in good faith by vote of the stockholders; or

           (3) The contract or transaction is fair as to the corporation as of
the time it is authorized, approved or ratified, by the board of directors, a
committee thereof, or the stockholders.

     (b)   Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the board of directors or of a committee
which authorizes the contract or transaction.

                                       6
<PAGE>

     4.15  Resignation or Removal of Directors.  Unless otherwise restricted by
           -----------------------------------
the certificate of incorporation or by law, any director or the entire board of
directors may be removed, with or without cause, by the holders of a majority of
the stock issued and outstanding and entitled to vote at an election of
directors. Any director may resign at any time by delivering his resignation in
writing to the president or the secretary or to a meeting of the board of
directors.  Such resignation shall be effective upon receipt unless specified to
be effective at some other time; and without in either case the necessity of its
being accepted unless the resignation shall so state.  No director resigning and
(except where a right to receive compensation shall be expressly provided in a
duly authorized written agreement with the corporation) no director removed
shall have any right to receive compensation as such director for any period
following his resignation or removal, or any right to damages on account of such
removal, whether his compensation be by the month or by the year or otherwise;
unless in the case of a resignation, the directors, or in the case of removal,
the body acting on the removal, shall in their or its discretion provide for
compensation.

     Section 5.    NOTICES
     ---------     -------

     5.1  Form of Notice.  Whenever, under the provisions of law, or of the
          --------------
certificate of incorporation or of these bylaws, notice is required to be given
to any director or stockholder, such notice may be given by mail, addressed to
such director or stockholder, at his address as it appears on the records of the
corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the time when the same shall be deposited in the United States mail.
Unless written notice by mail is required by law, written notice may also be
given by telegram, cable, telecopy, commercial delivery service, telex or
similar means, addressed to such director or stockholder at his address as it
appears on the records of the corporation, in which case such notice shall be
deemed to be given when delivered into the control of the persons charged with
effecting such transmission, the transmission charge to be paid by the
corporation or the person sending such notice and not by the addressee.  Oral
notice or other in-hand delivery (in person or by telephone) shall be deemed
given at the time it is actually given.

     5.2  Waiver of Notice.  Whenever notice is required to be given under the
          ----------------
provisions of law, the certificate of incorporation or these bylaws, a written
waiver thereof, signed by the person entitled to notice, whether before or after
the time stated therein, shall be deemed equivalent to notice.  Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
when the person attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.  Neither the business to be transacted at,
nor the purpose of, any meeting of the stockholders, directors or members of a
committee of the directors need be specified in any written waiver of notice.

     Section 6.    OFFICERS AND AGENTS
     ---------     -------------------

     6.1  Enumeration; Qualification.  The officers of the corporation shall be
          --------------------------
a president, a treasurer, a secretary and such other officers, if any, as the
board of directors from time to time may in its discretion elect or appoint
including without limitation one or more vice presidents.  Any officer may be,
but none need be, a director or stockholder.  Any two or more offices may be
held by the same person.  Any officer may be required by the board of directors
to secure the

                                       7
<PAGE>

faithful performance of his duties to the corporation by giving bond in such
amount and with sureties or otherwise as the board of directors may determine.

     6.2  Powers.  Subject to law, to the certificate of incorporation and to

compensation shall be expressly provided in a duly authorized written agreement
with the corporation) no officer removed shall have any right to any
compensation as such officer for any period following his resignation or
removal, or any right to damages on account of such removal, whether his

the certificate of incorporation and the bylaws, be prescribed from time to time
by the board of directors.  Such certificate shall be signed by the president or
a vice-president and (i) the treasurer or an assistant treasurer or (ii) the
secretary or an assistant secretary.  Any of or all the signatures on the
certificate may be a facsimile.  In case an officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed on such certificate
shall have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the corporation with the same effect
as if he were such officer, transfer agent, or registrar at the time of its
issue.

     7.2  Lost Certificates.  The board of directors may direct a new
          -----------------
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the board of
directors may, in its

                                       9
<PAGE>

discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require

against any claim that may be made against the corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

the corporation by the surrender to the corporation or its transfer agent of the
certificate therefor properly endorsed or accompanied by a written assignment
and power of attorney properly executed, with necessary transfer stamps affixed,
and with such proof of the authenticity of signature as the board of directors
or the transfer agent of the corporation may reasonably require.  Except as may
be otherwise required by law, by the certificate of incorporation or by these
bylaws, the corporation shall be entitled to treat the record holder of stock as
shown on its books as the owner of such stock for all purposes, including the
payment of dividends and the right to receive notice and to vote or to give any
consent with respect thereto and to be held liable for such calls and
assessments, if any, as may lawfully be made thereon, regardless of any
transfer, pledge or other disposition of such stock until the shares have been
properly transferred on the books of the corporation.

     It shall be the duty of each stockholder to notify the corporation of his
post office address.

     Section 9.    GENERAL PROVISIONS

other lawful action, the board of directors may fix, in advance, a record date,
which shall not be more than sixty days nor less than ten days before the date
of such meeting, nor more than sixty days prior to any other action to which
such record date relates.  A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment

     (a)   The record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held;

     (b)   The record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the board of directors is necessary, shall be the day on which the first
written consent is expressed; and

of incorporation.

     9.3  Payment of Dividends.  Before payment of any dividend, there may be
          --------------------
set aside out of any funds of the corporation available for dividends such sum
or sums as the directors from time to time, in their absolute discretion, think
proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or  for repairing or maintaining any property of the corporation, or
for such other purpose as the directors shall think conducive to the interest of
the corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

     9.4  Checks.  All checks or demands for money and notes of the corporation
          ------

          ----
seal.  The corporate seal shall have inscribed thereon the name of the
corporation, the year of its organization and the word "Delaware."  The seal may
be used by causing it or a facsimile thereof to be impressed or affixed or
reproduced or otherwise.  The seal may be altered from time to time by the board
of directors.

     Section 10.    INDEMNIFICATION
     ----------     ---------------

     10.1  It being the intent of the corporation to provide maximum protection
available under the law to its officers and directors, the corporation shall
indemnify its officers and directors to the full extent the corporation is
permitted or required to do so by the General Corporation Law of Delaware.  In
furtherance of and not in limitation of the foregoing, the corporation shall
advance expenses, including attorneys' fees, incurred by an officer or director
of the corporation in defending any civil, criminal, administrative or
investigative action, suit or  proceeding in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of such director or officer to repay such advances if it shall be ultimately
determined that he is not entitled to be indemnified by the corporation.  The
corporation shall have the power to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the
corporation, or who is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against any liability asserted against such
person and incurred by such person in any such capacity, or arising out of such
person's status

                                      11
<PAGE>

as such, whether or not the corporation has the power to indemnify such person
under the General Corporation Law of Delaware.

adopted by the stockholders or by the board of directors when such power is
conferred upon the board of directors by the certificate of incorporation, at
any regular meeting of the stockholders or of the board of directors or at any
special meeting of the stockholders or of the board of directors.  If the power
to adopt, amend or repeal bylaws is conferred upon the board of directors by the
certificate of incorporation, it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.

                        Report of Independent Auditors

The Board of Directors
Sequenom, Inc.


We have audited the accompanying consolidated balance sheet of Sequenom, Inc. (a
development stage company) as of December 31, 1997 and the related consolidated
statements of operations, stockholders' equity (deficit), and cash flows for the
year ended December 31, 1997 and the period from February 14, 1994 (inception)
through December 31, 1997.  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 audit.  The
financial statements as of December 31, 1996, and for the period February 14,
1994 (inception) through December 31, 1996, were audited by other auditors whose
report dated May 15, 1997 expressed an unqualified opinion on those statements.
The financial statements for the period February 14, 1994 (inception) through
December 31, 1996 include total revenues and net loss of $917,994 and
$(6,283,696), respectively.  Our opinion on the statements of operations,
stockholders' equity, and cash flows for the period February 14, 1994
(inception) through December 31, 1997, insofar as it relates to amounts for
prior periods through December 31, 1996, is based solely on the report of other
auditors.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the consolidated financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the consolidated 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 and the report of other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audit and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Sequenom, Inc.  ( a development
stage company) at December 31, 1997, and the result of its operations and its
cash flows for the year then ended and the period from February 14, 1994
(inception) through December 31, 1997, in conformity with generally accepted
accounting principles.

                   Notes to Consolidated Financial Statements

                               December 31, 1997

1.  NATURE OF THE BUSINESS

Sequenom, Inc. (the "Company") was incorporated on February 14, 1994 in the
State of Delaware.  The Company is focused on developing high definition DNA
analysis tools for industrial biomedical and life science applications.

Since inception, the Company has devoted its efforts to establishing its
business, raising capital and recruiting personnel.  Accordingly, through the
date of these financial statements, the Company is considered to be a
development stage enterprise.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation

The accompanying consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiary, Sequenom GmbH.  All significant
intercompany transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consists of highly liquid investments with original maturities
when purchased of less than three months.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of
credit risk consist of demand deposits.

                                                                               6

            Notes to Consolidated Financial Statements (continued)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Property, Equipment and Leasehold Improvements

Property and equipment are stated at cost and depreciated using the straight-
line method over the estimated useful lives of the assets.  Leasehold
improvements are amortized using the straight-line method over the life of the
improvement or the remaining term of the lease, whichever is shorter.

Organization Costs

Organization costs of $40,000, consisting of legal fees related to the formation
of the Company, are being amortized on the straight-line basis over a five-year
period.

Asset Impairment

The Company adopted Statement of Financial Accounting Standards ("SFAS") No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of, effective January 1, 1996.  SFAS No. 121 requires
impairment losses to be recorded on long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amount.  SFAS
No. 121 also addresses the accounting for long-lived assets that are expected to
be disposed of.  The adoption had no impact on the Company's financial
statements.

Revenue Recognition

Grant revenue is recorded as the research expenses relating to the grants as
incurred.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

The Company accounts for income taxes according to SFAS No. 109, Accounting for
Income Taxes.  Under the asset and liability method specified by SFAS No. 109, a
deferred tax asset or liability is determined based on the difference between
the financial statement and tax basis of assets and liabilities as measured by
the enacted tax rates which will be in effect when these differences reverse.


                                                                               7

            Notes to Consolidated Financial Statements (continued)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

The Company provides a valuation allowance against net deferred tax assets if,
based upon the available evidence, it is more likely than not that some or all
of the deferred tax assets will not be realized.

Stock-Based Compensation

Effective January 1, 1997, the Company adopted the footnote disclosure
provisions of SFAS No. 123, Accounting for Stock-Based Compensation.  SFAS No.
123 permits entities to adopt a fair value-based method of accounting for stock-
based compensation arrangements, under which compensation cost is determined
using the fair value of the stock option at the grant date and the number of
options vested, and is recognized over the periods in which the related services
are rendered.  However, it also allows an entity to continue measuring
compensation cost for stock-based compensation using the intrinsic value method
of accounting prescribed by Accounting Principles Board Opinion No. 25 ("APB
25"), Accounting for Stock Issued to Employees.  The Company has elected to
continue to apply the provisions of APB 25 and provide pro forma footnote
disclosures required by SFAS No. 123.

Comprehensive Income and Segment Information

In June 1996, the Financial Accounting Standards Board issued SFAS No. 130,
Reporting Comprehensive Income and SFAS No. 131, Disclosure about Segments of an
Enterprise and Related Information.  SFAS No. 130 requires that all components
of comprehensive income be reported in the period in which they are recognized
and is effective for fiscal 1998.  SFAS No. 131 establishes standards for
disclosures of an entity's reportable operating segments, and is also effective
in fiscal 1998.  The Company is in process of evaluating the disclosure
requirements of the new standards, the adoption of which is not expected to have
a material impact on the consolidated financial statements.

                                                   =========================

Total depreciation and amortization expense for the years ended December 31,
1997 and 1996 amounted to $351,173 and $314,195, respectively.

4.  LONG-TERM DEBT

In 1995, the Company and its wholly-owned subsidiary, Sequenom GmbH, entered
into agreements with a  German bank for two loans, one for DM 1 million
(approximately $697,800) and the other for DM 3 million (approximately
$2,093,400).  In 1997, the Company and subsidiary entered into another agreement
with the same German bank for an additional loan of DM 2 million (approximately
$1,116,000).  The loans are unsecured, and must be preceded by an equity
contribution of the same amount by the Company to the subsidiary.  As of
December 31, 997, the Company had made such equity contributions and the
subsidiary had borrowed the entire DM 6 million under the agreements.

Interest is payable semi-annually on the loans.  The 1995 loans began accruing a
nominal interest of 6% on March 31, 1997, while payments commenced in June 1997.
The effective nominal interest rate over the life of the 1995 loans is 4.8%.
The 1997 loan bears interest at 7% with payments commencing in 1998.  The
subsidiary is also required to pay additional interest equal to 9% of the
subsidiary's annual profits, to the extent that such profits exceed DM 100,000
per year.  The combined annual interest rate (nominal interest and additional
interest) may not exceed 7% per year through December 31, 2000.  Commencing
January 1, 2001 and January 1, 2003, any amounts still outstanding will accrue
additional interest at 6% and 7% per annum for the 1995 loans and 1997 loan,
respectively.  Principal is due in full on December 31, 2005 and December 31,
2007 or earlier upon certain events, as defined in the 1995 and 1997 loan
agreements, respectively.


                                                                               9

            Notes to Consolidated Financial Statements (continued)

4.  LONG TERM DEBT (CONTINUED)

In addition, at the end of the loan term (earlier of repayment or December 31,
2005 and December 31, 2007 for the 1995 loans and 1997 loan, respectively), the
subsidiary is obligated to pay a terminal interest equal to 25%, 30% and 35% of
the amounts loaned under the DM I million, DM 3 million and DM 2 million
agreements, respectively, estimated to be $1,0.41,606 u of December 31, 1997.
The bank may elect to forego such payments in certain situations.  The Company
anticipates that the full amount borrowed under these loans will be repaid in
the year 2000.

Under certain conditions, the Company may exercise a "put option" to sell its
shares of capital stock in the subsidiary to the German bank for an amount equal
to 50% of the Company's equity contribution to the subsidiary pursuant to the DM
3 million loan.  Through December 31, 1997, the Company had made capital
contributions to the subsidiary under the DM 3 million loan agreement of DM 3
million (approximately $1,674,000); therefore, the potential amount recoverable
under this "put option" was approximately DM 1.5 million (approximately
$837,000) at December 31, 1997.  If the Company exercises such put option, then
the Series B Preferred Stockholders have a right to elect redemption of their
Series B Preferred Stock in the amount of $1.50 per share.  At the present time
the Company has no intention of exercising the "put option."

5.  STOCKHOLDERS' EQUITY

Pursuant to the Company's Certificate of Incorporation, as amended, the Company
has authorized the issuance of 17,209,744 shares of capital stock par value
$0.001 per share, consisting of 9,218,000 shares of Common Stock ("Common
Stock"), 1,650,000 shares of Series A Convertible Preferred Stock ("Series A
Preferred Stock"), 2,976,663 shares of Series B Convertible Preferred stock
("Series B Preferred Stock"), and 3,365,081 shares of Series C Convertible
Preferred Stock ("Series C Preferred Stock").

All shares of stock have voting rights.  Holders of Common Stock have one vote
per share, while holders of Series A, Series B, and Series C Preferred Stock are
entitled to the number of votes per share equal to the number of shares of
Common stock into which each Preferred share could be converted.

PREFERRED STOCK

Each share of Preferred Stock is convertible into one share of Common Stock at
any time at the option of the holder.  The rate at which the Preferred Stock
convert to Common Stock is subject to adjustment in certain circumstances.  All
outstanding shares of Series C Preferred Stock shall


                                                                              10

automatically convert to Common Stock upon the closing of a firm commitment
underwritten public offering with a price per share of not less than $9.45 and
with gross proceeds to the Company of not less than $20 million.  All
outstanding shares of Series B and Series A Preferred Stock shall automatically
convert to Common Stock upon the closing of a firm commitment underwritten
public offering with a price per share of not less than $4.50 and $2.50,
respectively, and with gross proceeds to the Company of not less than $10
million.

The holders of the Series B Preferred Stock shall be entitled to receive, from
funds legally available therefore, a noncumulative dividend at the rate of $0.05
per share per annum, payable when and as declared by the Board of Directors.  No
dividends shall be declared or paid to the holders of Series A Preferred Stock
or Common Stock unless the holders of Series B and Series C Preferred Stock have
been paid in full all of the dividends to which they are entitled, nor shall any
dividends be declared or paid to the holders of Series A Preferred Stock or
Common stock at a rate greater than the rate paid to the holders of Series B and
Series C Preferred Stock.  If dividends are paid on Series A or B Preferred
Stock, the holders of the Series C Preferred Stock are entitled to receive a
dividend at the same rate per share.

The Series B and Series C Preferred Stock have preference as to the assets of
the Company upon liquidation over the Series A Preferred Stock and the Common
Stock; the Series A Preferred Stock has preference over the Common Stock.  In
liquidation, the holders of Series B Preferred Stock and Series A Preferred
Stock are entitled to the greater of (a) the amount per share as would have been
payable had all shares of Series B Preferred Stock or Series A Preferred Stock
been converted to Common Stock immediately prior to such event of liquidation,
plus all declared but unpaid dividends or (b) for the Series C preferred stock,
$3.15 per share plus declared but unpaid dividends, for the Series B Preferred
Stock, $1.50 per share plus declared but unpaid dividends and, for the Series A
Preferred Stock, $0.50 per share plus declared but unpaid dividends.

The holders of Series B Preferred Stock have redemption rights under certain
limited conditions as discussed in Note 4.

In December 1995, the Company issued 2,333,333 shares of Series B Convertible
Preferred Stock to a group of investors for gross proceeds of $3,500,000.  In
August 1995 the Company also issued 26,250 shares of Common Stock to one
investor for proceeds of $1,313.

In February 1996, the Company issued 643,330 shares of Series B Convertible
Stock to various investors for gross proceeds of $964,995.


                                                                              11

5.  STOCKHOLDERS' EQUITY (CONTINUED)

In May 1997, the Company issued 1,065,079 shares of Series C Convertible Stock
to various investors for gross proceeds of $3,355,000.

COMMON STOCK

In February 1994, the Company issued 420,000 shares of Common Stock at $0.05 per
share to three individuals (the "founders"), for gross proceeds of $21,000.
These shares were subsequently exchanged for 42,000 shares of Series A Preferred
stock.  In March 1994, the Company issued 380,000 shares of Common Stock, at a
value of $0.05 per share, which were subsequently exchanged for 38,000 shares of
Series A Preferred Stock, to one of the founders for consulting services.  The
Company recorded expense of $19,000 related to this issuance of shares.

In May 1994, the Company issued 400,000 shares of Common Stock at $0.50 per
share to a group of investors for gross proceeds of $200,000.  Contemporaneously
with this issuance of shares, the Company issued 1,100,000 shares of Common
Stock at a value of $0.50 per share to one of the founders in exchange for the
assignment of the rights to all inventions (and related documentation) which had
been developed by the founder.  Accordingly, $550,000 has been recorded as
research and development expense in the accompanying financial statements.
These shares were subsequently exchanged for 400,000 shares and 1,100,000 shares
of Series A Preferred Stock, respectively.

1994 STOCK PLAN

In February 1994, the Company adopted the 1994 Stock Plan (the "Plan").  The
Plan provides for the grant of options to purchase Common Stock and the issuance
of shares of Common Stock subject to Company repurchase rights to directors,
officers, employees and consultants to the Company.  Options granted to
employees generally vest over four years at the rate of 25% per year with a
maximum term of 10 years.  Options granted to consultant shave vesting periods
determined at the date of grant.  The number of shares of Common Stock issuable
under the Plan was 1,700,000 in 1997 and 1,000,000 in 1996.


                                                                              12

5.  STOCKHOLDERS' EQUITY (CONTINUED)

Of the 731,000 options issued in 1997, 3,000 were exercisable in full on the
date of grant with the remaining exercisable ratably over a four-year period.
Of the 435,000 options issued in 1996, 67,000 were exercisable in full on the
date of grant, 36,000 were exercisable ratably over a six-month period and the
remaining 332,000 were exercisable over a five year period.  Of the 370,000
options issued in 1995, 222,000 were exercisable in full on the date of grant,
30,000 were exercisable ratably over a five-year period and an additional
118,000 are subject to a vesting schedule as follows - 22,000 became immediately
exercisable and 96,000 are exercisable on the earlier of November 1, 2003, or
the achievement of certain milestones, as defined.  None of these milestones had
been achieved as of December 31, 1997.

The Company accounts for the stock option plan under APB No. 25, under which no
compensation cost has been recognized.  Had compensation cost for this plan been
determined consistent with SFAS No. 123, the Company's net loss would have been
changed to the following pro forma amounts:

                                             1997                1996
                                    ------------------------------------
  Adjusted pro forma net loss            $(4,819,703)       $(3,416,437)

Pro forma information regarding net loss has been determined as if the Company
has accounted for its employee stock options under the fair value method
prescribed in SFAS No. 123.  The fair value of these options was estimated at
the date of grant using the minimal value pricing model with the following
weighted average assumptions for 1997 and 1996: risk-free interest rate of 6%;
dividend yield of 0%; and a weighted-average life of the option of four years.

The minimal value pricing model is similar to the Black-Scholes option valuation
model which was developed for use in estimating the fair value of traded options
which have no vesting restrictions and are fully transferable, except that it
excludes the factor for volatility.  In addition, option valuation models
require the input of highly subjective assumptions.  Because the Company's
employee stock options have characteristics significantly different from those
of traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of the fair value of
its employee stock options.

6.  INCOME TAXES

Deferred income taxes reflect the net effects of temporary differences between
the carrying amounts of assets and liabilities for financial reporting purpose
and the amounts used for income tax purposes.  Significant components of the
Company's deferred tax assets are shown below.  A valuation allowance of
$4,621,000 has been recognized as realization of such assets is uncertain.

  Compliance with State Securities Laws in connection with Stock Option Grants
  ----------------------------------------------------------------------------


     The Corporation granted stock options to various individuals between the
dates of  February, 1994 and September, 1998 under the Corporation's 1994 Stock
Plan (the "Plan").  The shares of the Corporation's Common Stock that are
subject to the grants were not qualified or exempted under applicable state
securities laws and therefore the options may have been granted in violation of
such laws.  As a result, the Corporation may have potential liability to some or
all of the individuals to whom the options were granted.  The Corporation is
currently analyzing this matter and cannot, at this time, ascertain the extent
of its potential liability, if any.  Nevertheless, the Corporation does not
believe that such potential liability, if any, would exceed $200,000 in the
aggregate.

                              AMENDED AND RESTATED
                         REGISTRATION RIGHTS AGREEMENT

     This Amended and Restated Registration Rights Agreement (this "Agreement")
is entered into as of December 21, 1998 by and among Sequenom, Inc., a Delaware

Convertible Preferred Stock Purchase Agreement dated as of the date hereof (the
"Purchase Agreement"), including any Additional Investors as defined in the
Purchase Agreement (such purchasers of Series D Preferred Stock being
hereinafter sometimes referred to individually as an "Investor" and collectively
as the "Investors").

     WHEREAS, the Corporation, the Series B Investors and the Series C Investors
are the parties to a Registration Rights Agreement dated as of May 8, 1997, as
amended as of January 12, 1998 (the "Prior Registration Rights Agreement"),
pursuant to which the Corporation granted certain registration rights to the
Series B Investors, the Series C Investors and certain of their transferees;

     WHEREAS, the Corporation now wishes to sell to the Investors certain shares
of its Series D Preferred Stock;

     WHEREAS, the Series B Preferred Stock, the Series C Preferred Stock and the
Series D Preferred Stock are convertible into shares of the Corporation's Common
Stock; and

     WHEREAS, as a condition to entering into the Purchase Agreement, the
Investors have required that the Corporation, the Series B Investors and the
Series C Investors execute this Agreement to provide the Investors rights to
register the shares of Common Stock issuable upon conversion of their Series D
Preferred Stock and certain other securities of the Corporation described below;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
hereinafter set forth, the parties hereto agree as follows:

     1.  Definitions.  As used in this Agreement, the following terms shall have
         -----------
the following meanings:

         (a) The term "Act" means the Securities Act of 1933, as amended;
                                      ----------

         (b) The term "Holder" means any Investor, any Series B Investor, any
                                         --------
Series C Investor and any other person or entity holding Registrable Securities
to whom the registration rights granted in this Agreement have been transferred
pursuant to Section 14 hereof;

         (c) The term "Preferred Stock" means the Series B Preferred Stock, the
Series C Preferred Stock and the Series D Preferred Stock;
<PAGE>

         (d) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement; and

         (e) The term "Registrable Securities" means (1) the Common Stock
issuable upon conversion of the Preferred Stock, (2) Common Stock purchased by
an Investor pursuant to Section 8.1 of the Purchase Agreement (or Common Stock
for or into which New Securities (as therein defined) purchased by the Investor
pursuant to such Section 8.1 may be exercised or converted) or pursuant to the
Stock Restriction Agreement dated as of the date hereof among the Corporation,
the Series B Investors, the Series C Investors, the Investors and certain
additional parties identified therein, and (3) any Common Stock of the
Corporation issued as a dividend or other distribution with respect to, or in
exchange or in replacement of, such Preferred Stock or Common Stock.

     In addition, for purposes of all calculations and notices under this
Agreement, and all other provisions of this Agreement where the context permits,
the term "Registrable Securities" shall include securities issuable upon
conversion of the Preferred Stock, a holder of the Preferred Stock shall be
deemed the Holder of such securities and such securities shall be deemed
outstanding Registrable Securities hereunder.  Notwithstanding the foregoing,
nothing in this Agreement shall require the Corporation actually to register any
shares of the Preferred Stock.

     2.  Request for Registration.  If at any time after the earlier of (i) the
         ------------------------
first underwritten public offering of securities for the account of the
Corporation, and (ii) the date two (2) years from the date hereof, the
Corporation shall receive a written request (specifying that it is being made
pursuant to this Section 2) from the Holder or Holders at least fifty percent
(50%) of the then outstanding Registrable Securities that the Corporation file a
registration statement under the Act, or a similar document pursuant to any
other statute then in effect corresponding to the Act, covering the registration
of at least the lesser of (i) at least twenty-five percent (25%) of the then
outstanding Registrable Securities and (ii) Registrable Securities the expected
price to the public of which equals or exceeds $10,000,000, then the Corporation
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that Holders have requested be
registered to be registered under the Act.

     Notwithstanding the foregoing, (a) the Corporation shall not be obligated
to effect a registration pursuant to this Section 2 during the period starting
with the date sixty (60) days prior to the Corporation's estimated date of
filing of, and ending on a date six (6) months following the effective date of,
a registration statement pertaining to an underwritten public offering of
securities for the account of the Corporation, provided that the Corporation is
actively employing in good faith its best efforts to cause such registration
statement to become effective and that the Corporation's estimate of the date of
filing such registration statement is made in good faith; (b) the Corporation
shall not be obligated to effect a registration pursuant to this Section 2
within six (6) months after the effective date of a prior registration under
such Section; (c) if the Corporation shall furnish to the Holders a certificate
signed by the President of the Corporation stating that in the good faith
judgment of the Board of Directors it would be seriously detrimental to the
Corporation or its stockholders for a registration statement to be filed in the
near future, then the Corporation's obligation to use its best efforts to file a
registration

                                      -2-
<PAGE>

statement shall be deferred for a period not to exceed three (3) months; and (d)
the Corporation may postpone a registration pursuant to this election for such
period of time as may be required to permit the use of regular audited year-end
financial statements with supplemental short period figures for a period not
exceeding six (6) months unless the Holders agree to bear the costs of any
special audit.

     The Corporation shall not be obligated to effect more than two (2)
registrations pursuant to this Section 2. Any request for registration under
this Section 2 must be for a firm commitment underwritten public offering to be
managed by an underwriter or underwriters of recognized national standing
reasonably acceptable to the Corporation.

     3.  Corporation Registration.  Subject to Section 8 of this Agreement, if
         ------------------------
at any time the Corporation proposes to register any of its Common Stock under
the Act in connection with the public offering of such securities for its own
account or for the accounts of other stockholders, solely for cash on a form
that would also permit the registration of the Registrable Securities, the
Corporation shall, each such time, promptly give each Holder written notice of
such determination.  Upon the written request of any Holder given within thirty
(30) days after mailing of any such notice by the Corporation, the Corporation
shall, subject to the limitations set forth in Section 8(a), use its best
efforts to cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested be registered.

     4.  Obligations of the Corporation.  Whenever required under Section 2, 3,
         ------------------------------
or 11 to use its best efforts to effect the registration of any Registrable
Securities, the Corporation shall, as expeditiously as reasonably possible:

         (a) Prepare and file with the Securities and Exchange Commission
("SEC") a registration statement with respect to such Registrable Securities and
use its best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a so-
called "shelf registration"), the Corporation shall in no event be obligated to
cause any such registration to remain effective for more than one hundred eighty
(180) days.

         (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

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

         (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably appropriate for the
distribution of the securities covered by the registration statement, provided
that the Corporation shall not be required in connection therewith or as a

                                      -3-
<PAGE>

condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions, and further provided
that (anything in this Agreement to the contrary notwithstanding with respect to
the bearing of expenses) if any jurisdiction in which the securities shall be
qualified shall require that expenses incurred in connection with the
qualification of the securities in that jurisdiction be borne by selling
stockholders, then such expenses shall be payable by selling stockholders pro
rata, to the extent required by such jurisdiction.

         (e) Provide a transfer agent for the Common Stock no later than the
effective date of the first registration of any Registrable Securities.

     5.  Furnish Information.  It shall be a condition precedent to the
         -------------------
obligations of the Corporation to take any action pursuant to this Agreement
that the Holders shall furnish to the Corporation such information regarding
them, the Registrable Securities held by them, and the intended method of
disposition of such securities as the Corporation shall reasonably request and
as shall be required in connection with the action to be taken by the
Corporation.

     6.  Expenses of Demand Registration.  All expenses incurred in connection
         -------------------------------
with registrations pursuant to Section 2 (excluding underwriters' discounts and
commissions), including, without limitation, all registration and qualification
fees, printers, and accounting fees, fees and disbursements of counsel for the
Corporation, and the reasonable fees and disbursements of one special counsel
for the selling Holders, shall be borne by the Corporation.

     7.  Corporation Registration Expenses.  All expenses (excluding
         ---------------------------------
underwriters' discounts and commissions) incurred in connection with a
registration pursuant to Section 3, including, without limitation, any
additional registration and qualification fees and any additional fees and
disbursements of counsel to the Corporation that result from the inclusion of
securities held by the Holders in such registration and the reasonable fees and
disbursements of one special counsel for the selling stockholders, shall be
borne by the Corporation; provided, however, that if the registration is of
exclusively a secondary offering, the holders shall bear their proportionate
share of the expenses incurred in connection with any registration (provided all
stockholders registering shares thereunder bear their proportionate share of
expenses), except expenses which the Corporation would have incurred whether or
not the securities held by the Holders were included in such registration
(including, without limitation, the expense of preparing normal audited or
unaudited financial statements).

     8.  Underwriting Requirements.
         -------------------------

         (a) In connection with any offering involving an underwriting of
shares being issued by the Corporation, the Corporation shall not be required
under Section 3 to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Corporation and the underwriters selected by it, and then only in
such quantity as will not, in the reasonable opinion of the underwriters,
jeopardize the success of the offering by the Corporation.  If the total amount
of securities that all Holders request to be included in an underwritten
offering exceeds the amount of securities that the underwriters reasonably
believe compatible with the success of the offering, the Corporation

                                      -4-
<PAGE>

shall only be required to include in the offering so many of the securities of
the selling Holders as the underwriters reasonably believe will not jeopardize
the success of the offering (the securities so included to be apportioned pro
rata among the selling Holders according to the total amount of securities owned
by said selling Holders, or in such other proportions as shall mutually be
agreed to by such selling Holders), provided that in the case of an offering
involving shares being issued by the Corporation, no such reduction shall be
made with respect to any securities offered by the Corporation for its own
account, and provided further that no securities of any stockholder who is not a
Holder shall be included in such offering, other than securities of stockholders
who have initiated such registration pursuant to the exercise of contractual
rights to do so, unless all securities which the Holders have requested to be
included are included on a pro rata basis with the securities of any other
stockholders who have a contractual right to include their securities in such
offering.

         (b) With respect to any underwriting of shares to be registered under
Section 2, or an underwriting of shares to be registered under Section 11, if
the Holders of a majority of the then outstanding Registrable Securities have
requested registration thereunder, such Holders shall have the right to
designate the managing underwriter or underwriters, subject to the consent of
the Corporation.  In all other circumstances under such Sections and in
connection with registrations under Section 3, the Corporation shall have the
right to designate the managing underwriter or underwriters, subject to the
consent of the Holders of a majority of the Registrable Securities participating
in the underwriting.  In any such case, such consent shall not be unreasonably
withheld or delayed.

     9.  Delay of Registration.  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 Agreement.

    10.  Indemnification.  In the event any Registrable Securities are included
         ---------------
in a registration statement under this Agreement:

         (a) To the extent permitted by law, the Corporation will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person, if any, who
controls such Holder or underwriter within the meaning of the Act, against any
losses, claims, damages or liabilities, joint or several, to which they 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
on any untrue or alleged untrue statement of any material fact contained in such
registration statement, including, without limitation, any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, 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 or arise out of any
violation by the Corporation of any rule or regulation promulgated under the Act
applicable to the Corporation and relating to action or inaction required of the
Corporation in connection with any such registration; and will reimburse each
such Holder, such underwriter, or controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action, provided, however,
that the indemnity agreement contained in this Section 10(a) shall not apply

                                      -5-
<PAGE>

to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Corporation
(which consent shall not be unreasonably withheld or delayed) nor shall the
Corporation be liable in any such case for any such loss, claim, damage,
liability or action to the extent that it arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in connection with such registration statement, preliminary prospectus,
final prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person.

         (b) To the extent permitted by law, each Holder requesting or joining
in a registration will indemnify and hold harmless the Corporation, each of its
directors, each of its officers who has signed the registration statement, each
person, if any, who controls the Corporation within the meaning of the Act, and
any underwriter for the Corporation (within the meaning of the Act) against any
losses, claims, damages or liabilities to which the Corporation or any such
director, officer, controlling person or underwriter may become subject, under
the Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, 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,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such
registration statement, preliminary prospectus or final prospectus, or
amendments or supplements thereto, in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and will reimburse the Corporation or any such director,
officer, controlling person or underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 10(b) 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 such Holder (which consent shall
not be unreasonably withheld) and provided further that no Holder shall have any
liability under this Section 10(b) in excess of the net proceeds actually
received by such Holder in the relevant public offering.

         (c) Promptly after receipt by an indemnified party under this Section
10 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against any indemnifying party under
this Section 10, notify the indemnifying party in writing of the commencement
thereof and the indemnifying party shall have the right to participate in, and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with counsel
mutually satisfactory to the parties.  The failure to notify an indemnifying
party promptly, of the commencement of any such action, if prejudicial to his
ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this Section 10, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this Section 10.

                                      -6-

     11.  Registrations on Form S-3.
          -------------------------

          (a) If (i) the Corporation shall receive a written request (specifying
that it is being made pursuant to this Section 11) from the Holder or Holders of
at least twenty-five percent (25%) of the then outstanding Registrable
Securities that the Corporation file a registration statement on Form S-3 (or
any successor form to Form S-3 regardless of its designation) for a public
offering of shares of the Registrable Securities the reasonably anticipated
aggregate price to the public of which would exceed Two Million Dollars
($2,000,000), and (ii) the Corporation is a registrant entitled to use Form S-3
to register such shares, then the Corporation shall use its best efforts to
cause such shares to be registered on Form S-3 (or any successor form to Form S-
3).

          (b) All expenses (excluding underwriters' discounts and commissions)
incurred in connection with the first two registrations requested pursuant to
Section 11(a), including, without limitation, all registration, qualification,
printing, and accounting fees, and fees and disbursements of one special counsel
to the selling Holder or Holders and counsel to the Corporation, shall be borne
by the Corporation.  All such expenses for registrations pursuant to Section
11(a) after the first two such registrations shall be borne by the Corporation,
except that the selling Holders shall pay all fees of their legal counsel, if
any, in connection therewith.

          (c) Holders' rights to registration under this Section 11 are in
addition to, and not in lieu of, their rights to registration under Sections 2
and 3 of this Agreement.

     12.  Reports Under Securities Exchange Act of 1934.  With a view to making
          ---------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Corporation to the public without registration, the
Corporation agrees to use its best efforts to:

          (a) make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Corporation;

          (b) file with the SEC in a timely manner all reports and other
documents required of the Corporation under the Act and the Securities Exchange
Act of 1934, as amended (the "1934 Act"); and

          (c) furnish to any Holder forthwith upon request a written statement
by the Corporation that it has complied with the reporting requirements of Rule
144 (at any time after ninety (90) days after the effective date of said first
registration statement filed by the Corporation), and of the Act and the 1934
Act (at any time after it has become subject to such reporting requirements), a
copy of the most recent annual or quarterly report of the Corporation, and such
other reports and documents so filed by the Corporation as may be reasonably
requested in availing any such holder to take advantage of any rule or
regulation of the SEC permitting the selling of any such securities without
registration.

     13.  Limitations in Connection with Future Grants of Registration Rights.
          -------------------------------------------------------------------
Without the prior written consent of the Holder or Holders of a majority of the
then outstanding Registrable Securities issued or issuable upon conversion of
the Preferred Stock, the Corporation shall not grant rights to cause the
Corporation to register any of its securities to any person or entity other than
the Additional Investors as contemplated hereunder.

     14.  Transfer of Registration Rights.  The registration rights of any
          -------------------------------
Series B Investor, Series C Investor or Investor (and of any permitted
transferee of any Series B Investor, Series C Investor or Investor or its
permitted transferees) under this Agreement with respect to any shares of
Registrable Securities may be transferred to any Affiliate of such Series B
Investor, Series C Investor or Investor or such permitted transferee, or to any
transferee who acquires (otherwise than in a registered public offering) at
least 20,000 shares of Registrable Securities held or acquired as of the date
hereof by such Series B Investor, Series C Investor or Investor; provided,
however, that the Corporation is given written notice by the Holder at the time
of such transfer stating the name and address of the transferee and identifying
the securities with respect to which the rights under this Agreement are being
assigned.  For such purpose, an "Affiliate" of any Series B Investor, Series C
Investor or Investor (or any such transferee) means any general or limited
partner of such Series B Investor, Series C Investor or Investor (or transferee)
if it is a partnership, or any person or entity that, directly or indirectly,
through one or more intermediaries, controls, or is controlled by, or is under
common control with, such Series B Investor, Series C Investor or Investor or
transferee.  In addition, for purposes of this section, in the case of any
Series B Investor, Series C Investor or Investor that is a limited partnership
for which TVM Techno Venture Management Limited Partnership, TVM Techno Venture
Management III GmbH or any of their respective Affiliates serves as a general
partner, the term "Affiliate" of any such Series B Investor, Series C Investor
or Investor shall include KBL Founder Ventures SCA, KB Lux Venture Capital Fund
- - European Biotechnology and their respective Affiliates and Alpinvest
International B.V. and its Affiliates.

     15.  Mergers, Etc.  The Corporation shall not, directly or indirectly,
          -------------
enter into any merger, consolidation or reorganization in which the Corporation
shall not be the surviving corporation unless the proposed surviving corporation
shall, prior to such merger, consolidation or reorganization, agree in writing
to assume the obligations of the Corporation under this Agreement, and for that
purpose references hereunder to "Registrable Securities" shall be deemed to be
references to the securities which the Holders would be entitled to receive in
exchange for Registrable Securities under any such merger, consolidation or
reorganization; provided, however, that the provisions of this Agreement shall
not apply in the event of any merger, consolidation or reorganization in which
the Corporation is not the surviving corporation if the Holders of Registrable
Securities are entitled to receive in exchange therefor (i) cash, or (ii)
securities of the acquiring corporation which may be immediately sold to the
public without registration under the Act.

     16.  Stand-Off Agreement.  Each Holder, if requested by the Corporation and
          -------------------
the managing underwriter of an offering by the Corporation of Common Stock or
other securities of the Corporation pursuant to a registration statement under
the Act, shall agree not to sell publicly or otherwise transfer or dispose of
any Registrable Securities or other securities of the

                                      -8-
<PAGE>

Corporation held by such Holder for a specified period of time (not to exceed
180 days) following the effective date of such registration statement; provided,
that:

          (a) such agreement shall only apply to the first registration
statement covering Common Stock to be sold on the Corporation's behalf to the
public in an underwritten offering; and

          (b) all holders of five percent (5%) or more of the shares of Common
Stock then outstanding (including shares of Common Stock issuable upon the
conversion of Preferred Stock, or other convertible securities, or upon the
exercise of options, warrants or rights) and all officers and directors of the
Corporation enter into similar agreements.

     17.  Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" for all purposes
of this Agreement.

     18.  Notices.  All notices, requests, consents and other communications
          -------
hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by first class mail postage
prepaid (other than to non-U.S. parties) or by fax or DHL, Federal Express or

                                   AGREEMENT
                                   ---------

     In consideration of the mutual covenants herein contained, the parties
hereto agree as follows:

     1.  Board of Directors.  The Stockholders agree to vote all shares of the
         ------------------
Corporation's Common Stock, $.001 par value per share ("Common Stock"), Series A
Convertible Preferred Stock, $.001 par value per share ("Series A Preferred
Stock"), Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock and any other class of voting security of the Corporation (the "Shares")
now or hereafter owned or controlled by them, and otherwise to use their
respective best efforts as stockholders of the Corporation, to set the number of
directors of the Corporation at five and to elect as directors, on the date of
this Agreement and in any subsequent election of directors of the Corporation:

         (a) one person designated by the Founders;

         (b) one person designated by the Original Investors;

         (c) one person designated by either (i) GLS LP Investment III Limited
("GLS") for so long as GLS holds at least 793,650 shares of Series C Preferred
Stock, or (ii) the holders of a majority of the Series C Preferred Stock if GLS
holds less than 793,650 shares of Series C Preferred Stock; and

         (d) two persons who are not employees of the Corporation (the
"Independent Directors"), who have experience in the Corporation's industry and
who are reasonably acceptable to a majority of the other directors.

<PAGE>

     Any person or entity or group of persons or entities entitled to make a
director designation hereunder (a "Designating Party") shall furnish written
notice to the Corporation at least 30 days prior to any election of directors of
its director-designee or director-designees and the Corporation shall furnish
written notice thereof to the Stockholders at least 10 days prior to any such
election of directors.  In the absence of such notice, the director-designee or
director-designees of such Designating Party then serving and previously
designated shall be reelected if still eligible to serve as provided herein.  In
the event that any Designating Party that is a group of Stockholders cannot
agree upon a director-designee, the identity of the director-designee of such
Designating Party shall be determined by a plurality in voting power of the
outstanding capital stock of the Corporation held by the Stockholders
constituting such Designating Party.

     This Agreement is not intended, and shall not be construed, to confer upon
any person designated hereunder for election to the Board of Directors any right
to serve or to continue to serve in such capacity.  Any Designating Party may,
at any time, determine to remove its then-current director-designee and
designate another person for election to the Board of Directors in place of the
person then serving as the director-designee of such Designating Party.  In the
event any such determination is made, the Stockholders shall promptly vote to
remove the director-designee of such Designating Party then serving, and to
elect as a director the replacement director-designee of such Designating Party.

     At any time a majority of the directors other than the Independent
Directors may determine to remove any Independent Director from the Board of
Directors and designate another person for election to the Board of Directors in
place of the person then serving as such Independent Director.  In the event any
such determination is made, the Stockholders shall promptly vote to remove the
applicable Independent Director and to elect as a director the replacement
Independent Director-designee.

     Any vacancy on the Board of Directors created by the resignation, removal,
incapacity, or death of any person designated under this Section 1 shall be
filled by another person designated by the original Designating Party.  The
Stockholders shall vote their respective Shares in accordance with such new
designation, and any such vacancy shall not be filled in the absence of a new
designation by the original Designating Party.

     This Section 1 shall terminate and be of no further force and effect upon
the closing of a firm commitment underwritten public offering of Common Stock of
the Corporation pursuant to an effective registration statement under the
Securities Act of 1933, as amended, in which the aggregate gross proceeds to the
Corporation from such offering are not less than $20,000,000 and the offering
price per share is not less than $10.00, appropriately adjusted to take account
of any stock split, stock dividend, combination of shares or similar event.

     In the event that any Designating Party (or its or their respective
partners, stockholders and affiliates) owns, in the aggregate, fewer than
200,000 shares of the Corporation's Common Stock, subject to adjustment for
stock splits, stock dividends, combinations of shares and similar events, such
Designating Party's right to make designations under this Section 1 shall
terminate, and the obligation of the other parties under this Section 1 to vote
for any members of the Board of Directors designated by such Designating Party
shall terminate, but all other obligations of all parties hereunder shall
continue unless otherwise terminated.  For purposes of this paragraph, in

                                      -2-
<PAGE>

determining the number of shares of Common Stock owned by a Designating Party,
ownership by such Designating Party of shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock
shall be deemed to be ownership by it of that number of shares of Common Stock
into which such shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock are convertible.

     2.  Director Indemnification.  In the event that any director contemplated
         ------------------------
by this Agreement shall be made or threatened to be made a party to any action,
suit or proceeding with respect to which he may be entitled to indemnification
by the Corporation pursuant to its Certificate of Incorporation, By-Laws or
otherwise, he shall be entitled to be represented in such action, suit or
proceeding by counsel of his choice and the expenses of such representation
shall be reimbursed by the Corporation to the extent provided in or authorized
by said Certificate of Incorporation or other provision and permitted by
applicable law.

     The Corporation and the Stockholders agree not to take any action to amend
any provision of the Certificate of Incorporation or By-Laws of the Corporation
relating to indemnification of directors, as presently in effect, without the
prior written consent of holders of at least two-thirds in voting power of the
Shares held by Founders, Original Investors, Series B Investors, Series C
Investors and the Investors, voting together as a single class.

     3.  Accession.  Any Additional Investors as defined in the Purchase
         ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such
                                                ---------
Additional Investor agrees to be bound by the obligations imposed under this
Agreement, whereupon such Additional Investor shall automatically become a party
to this Agreement and shall thereupon be deemed an "Investor" and a
"Stockholder" for all purposes of this Agreement.

     4.  Notices.  All notices, requests, consents and other communications
         -------
hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or duly sent by first class mail postage
prepaid (other than to non-U.S. parties), by fax, or by DHL, Federal Express or
any other internationally recognized express courier service, addressed to such
party at the address set forth below or such other address as may hereafter be

                    the books of the Corporation.


     5.  Assignment; Binding Effect.  No Designating Party may assign its or
         --------------------------
their rights hereunder.  Subject to termination or partial termination as
provided in Section 1, this Agreement shall be binding on the parties hereto and
their respective legal representatives, successors and permitted assigns and on
the transferees of any Shares now owned or hereafter acquired by them.

     6.  Entire Agreement; Amendment and Waiver.  This Agreement contains the
         --------------------------------------
sole and entire understanding of the parties with respect to its subject matter
and supersedes all prior negotiations, commitments, agreements and
understandings heretofore had among any of them with respect thereto.  Without
limiting the generality of the foregoing, this Agreement amends and restates the
Voting Agreement among the Corporation, the Founders, the Original Investors,
the Series B Investors and the Series C Investors dated as of May 8, 1997, as
amended as of January 12, 1998, which shall no longer have any force or effect.

waived, in whole or in part, except by the written agreement of the Corporation
and Stockholders or transferees of their rights hereunder holding at least two-
thirds in voting power of the Shares held by the Founders, two-thirds in voting
power of the Shares held by the Original Investors, two-thirds in voting power
of the Shares held by the Series B Investors, two-thirds in voting power of the
Shares held by the Series C Investors, and two-thirds in voting power of the
Shares held by the Investors.  A waiver on one occasion shall not constitute a
waiver on any further occasion.

     7.  Counterparts.  This Agreement may be executed in more than one
         ------------
counterpart, each of which shall be deemed to be an original and which,
together, shall constitute one and the same instrument.  Any such counterpart
may contain one or more signature pages.

     8.  Applicable Law.  This Agreement shall be governed by, and construed and
         --------------
enforced in accordance with, the substantive laws of the State of California,
without regard to its principles of conflicts of laws.

     9.  Legend.  Each certificate for Shares shall bear a legend stating in
         ------
substance as follows, and each of the Stockholders shall cause its certificates
to be so legended promptly after the execution and delivery of this Agreement:

     The shares of stock represented by this certificate are subject to the
     terms and provisions of a Voting Agreement among the Corporation and
     certain stockholders of the Corporation.  The Corporation will furnish a
     copy of

                                      -4-

         (d) "Series A Preferred Stock" means the Corporation's Series A
Convertible Preferred Stock, $.001 par value per share.

         (e) "Shares" shall mean and include all shares of Stock now owned or
hereafter acquired by any Founder or any Investor.

         (f) "Stock" shall mean and include all shares of Common Stock, all
Convertible Securities, all Options, and all other securities of the Corporation
which may be issued in exchange for or in respect of shares of Common Stock,
Convertible Securities or Options (whether by way of stock split, stock
dividend, combination of shares, reclassification, recapitalization,
reorganization, or any other means).

     2.  Prohibited Transfers.  None of the Investors or Founders shall sell or
         --------------------
otherwise transfer, by gift or otherwise, all or any part of his Shares except
in compliance with the terms of this Agreement.

     3.  Offer of Sale; Notice of Proposed Sale or Transfer.  If any Founder
         --------------------------------------------------
desires to sell or otherwise transfer any of his Shares, or of any interest
therein, whether voluntarily or by operation of law, in any transaction other
than pursuant to clauses (iii) or (iv) of Section 7(a) of this Agreement, such
Founder (the "Selling Founder") shall first deliver written notice of his desire
to do so (the "Selling Founder's Notice") to the Corporation and each of the
other Investors.  If any Investor desires to sell or otherwise transfer an
aggregate of 50,000 or more Shares in one transaction or multiple transactions,
or of any interest therein, whether voluntarily or by operation of law, other
than in connection with any transaction described in Section 8(c) of this
Agreement, such Investor (the "Selling Investor") shall first deliver written
notice of his desire to do so (the "Selling Investor's Notice") to the
Corporation.  The Selling Founder's Notice and the Selling Investor's Notice
must specify:  (i) the name and address of the party to which the Selling
Investor or Selling Founder proposes to sell or otherwise transfer the Shares or
an interest in the Shares (the "Proposed Transferee"), (ii) the number of Shares
the Selling Investor or Selling Founder proposes to sell or otherwise transfer
(the "Offered Shares"), (iii) the consideration per Share to be delivered to the
Selling Investor or Selling Founder for the proposed sale or transfer, and (iv)
all other material terms and conditions of the proposed transaction, which must
be bona fide.

     4.  Corporation's Option to Purchase Shares of Selling Founder.
         ----------------------------------------------------------

         (a) Except as set forth in Section 7(a), the Corporation shall have
the first option to purchase all or any part of the Offered Shares for the
consideration per Share and on the terms and conditions specified in the Selling
Founder's Notice.  The Corporation must exercise such option, no later than
fifteen (15) business days after such Selling Founder's Notice is deemed to have
been delivered to it, by written notice to the Selling Founder.

         (b) In the event the Corporation does not exercise its option within
such fifteen-business-day period with respect to all of the Offered Shares, the
Chief Financial Officer

                                      -2-
<PAGE>

of the Corporation shall, by the last day of such period, give written notice of
that fact to the Investors (the "Investor Notice"). The Investor Notice shall
specify the number of Offered Shares the Corporation has elected not to purchase
(the "Remaining Shares").

         (c) In the event the Corporation duly exercises its option to purchase
all or a portion of the Offered Shares, the closing of such purchase shall take
place at the offices of the Corporation on the later of (i) the date five
business days after the expiration of such fifteen-business-day period or (ii)
the date that the Investors consummate their purchase of Offered Shares under
Section 5(c) hereof.

         (d) To the extent that the consideration proposed to be paid by the
Proposed Transferee for the Offered Shares consists of property other than cash
or a promissory note, the consideration required to be paid by the Corporation
and/or the Investors exercising their options under Sections 4 and 5 hereof,
respectively, may consist of cash equal to the value of such property, as
determined in good faith by agreement of the Selling Founder and the Corporation
and/or the Investors acquiring such Offered Shares.

     5.  Investors' Option to Purchase and Right to Participate in Sales by
         ------------------------------------------------------------------
Founders.
- --------

         (a) Except as set forth in Section 7(a), each Investor shall have an
option, exercisable for a period of fifteen (15) business days from the date of
delivery of the Investor Notice, to purchase, on a pro rata basis, its
Proportionate Percentage (as defined below) of the Remaining Shares, for the
consideration per Share and on the terms and conditions set forth in the Selling
Founder's Notice.  Such option shall be exercised by delivery of written notice
to the Chief Financial Officer of the Corporation.  Alternatively, each Investor
may, within the same fifteen-business-day period, notify the Chief Financial
Officer of the Corporation of its desire to participate in the sale of Shares
and to sell, on the terms as set forth in the Selling Founder's Notice including
at the same price per Share on a common equivalent basis, up to an equivalent
proportion of the Series B Preferred Stock, Series C Preferred Stock and Series
D Preferred Stock owned by such Investor as the proposed sale of the Remaining
Shares represents with respect to the Shares then owned by the Selling Founder.

         (b) In the event options to purchase have been exercised by the
Investors with respect to some but not all of the Remaining Shares, the Chief
Financial Officer of the Corporation shall promptly give written notice of that
fact to those Investors who have exercised their options within such period (the
"Second Investor Notice").  The Second Investor Notice shall specify the number
of Remaining Shares the Investors have not elected to purchase (the "Additional
Remaining Shares").  The Investors who have exercised their options within the
fifteen-business-day period specified in Section 5(a) shall have an additional
option, for a period of ten (10) business days after delivery of the Second
Investor Notice, to purchase all or any part of the Additional Remaining Shares
on the terms and conditions set forth in the Selling Founder's Notice, which
option shall be exercised by the delivery of written notice to the Chief
Financial Officer of the Corporation.  In the event that there are two or more
such Investors that choose to exercise the last-mentioned option for a total
number of Additional Remaining Shares in excess of the number available, the
Additional Remaining Shares available for each such Investor's option shall be
allocated to such Investors pro rata based on that percentage calculated by
dividing (i) the number of Remaining Shares each such Investor elected to
purchase in

                                      -3-
<PAGE>

response to the Investor Notice by (ii) the aggregate number of Remaining Shares
elected to be purchased (in response to the Investor Notice) by all such
Investors, and only those Investors, electing to purchase any portion of the
Additional Remaining Shares (in response to the Second Investor Notice),
provided, however, that if the number of Additional Remaining Shares so
calculated for any such Investor exceeds the number of the Additional Remaining
Shares such Investor has elected to purchase, then that Investor shall receive
the number of Additional Remaining Shares such Investor has elected to purchase,
and the excess Additional Remaining Shares shall be reallocated on an equitable
basis (as determined by the Board of Directors of the Corporation) among the
remaining Investors electing to purchase any of the Additional Remaining Shares.

         (c) Promptly after the expiration of the last period for exercise of
an Investor's purchase option, the Chief Financial Officer of the Corporation
shall give written notice to the Selling Founder and the purchasing Investors,
specifying the number of Remaining Shares to be purchased by each purchasing
Investor.  The closing of the purchase of the Remaining Shares shall take place
at the offices of the Corporation no later than five (5) business days after
delivery of such notice to the Selling Founder and the purchasing Investors.

         (d) As used in this Section 5, the term "Proportionate Percentage"
shall mean with respect to each Investor a fraction, the numerator of which
shall be the amount of Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock owned by such Investor, and the denominator of which
shall be the total amount of Series B Preferred Stock, Series C Preferred Stock
and Series D Preferred Stock owned by all Investors, in each case on a common
equivalent basis.

     6.  Co-Sale.
         -------

         (a) If the Corporation and the Investors do not exercise their options
to purchase all of the Offered Shares within the periods described in this
Agreement (the "Option Period"), then each Investor which has, pursuant to
Section 5(a), expressed a desire to sell shares of Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock in the transaction (a
"Participating Investor") shall be entitled to do so pursuant to this Section.
The Chief Financial Officer of the Corporation shall promptly, on expiration of
the Option Period, notify the Selling Founder of the aggregate amount of Series
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock the
Participating Investors wish to sell.  The Selling Founder shall use his best
efforts to interest the Proposed Transferee in purchasing, in addition to the
Remaining Shares not subscribed for by the Investors, the Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock the Participating
Investors wish to sell.  If the Proposed Transferee does not wish to purchase
all of the Stock so made available by the Selling Founder and the Participating
Investors, then each Participating Investor and the Selling Founder shall be
entitled to sell, on the terms and conditions set forth in the Selling Founder's
Notice and on the same price per share on a common equivalent basis, a portion
of the Stock being sold to the Proposed Transferee, in the same proportion as
such Selling Founder or Participating Investor's ownership of Stock on a common
equivalent basis bears to the aggregate amount of Stock owned by the Selling
Founder and the Participating Investors on a common equivalent basis.  The
transaction contemplated by the Selling Founder's Notice shall be consummated
not later than 60 days after the expiration of the Option Period.

                                      -4-
<PAGE>

         (b) If the Participating Investors do not elect to sell the full
amount of Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock which they are entitled to sell pursuant to Section 6(a), the
Selling Founder shall be entitled to sell to the Proposed Transferee, according
to the terms set forth in the Selling Founder's Notice, that number of his
Shares which equals the difference between the amount of Stock desired to be
purchased by the Proposed Transferee and the number of shares of Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock the
Participating Investors wish to sell, in each case on a common equivalent basis.

         (c) If the Selling Founder wishes to sell or otherwise transfer any of
his Shares at a price per Share which differs from that set forth in the Selling
Founder's Notice, upon terms different from those previously offered to the
Corporation and the Investors, or more than 60 days after the expiration of the
Option Period, then, as a condition precedent to such transaction, such Shares
must first be offered to the Corporation and the Investors on the same terms and
conditions as given the Proposed Transferee, and the Investors must first be
offered the opportunity to participate in such transaction, in accordance with
the procedures and time periods set forth above.

     7.  Permitted Transfers.
         -------------------

         (a) Subject to the provisions of Section 7(b) and Section 8, the
Corporation's and the Investors' right of first refusal and the Investors' right
of co-sale described in Sections 4 through 6 shall not apply to:  (i) any
transfer of Shares by a Founder by gift or bequest or through inheritance to, or
for the benefit of, any member or members of such Founder's immediate family;
(ii) any transfer of Shares by a Founder to a trust (A) in respect of which such
Founder serves as trustee, provided that the trust instrument governing such
trust shall provide that such Founder, as trustee, shall retain sole and
exclusive control over the voting and disposition of such Shares until the
termination of this Agreement or (B) for the benefit solely of any member or
members of such Founder's immediate family; (iii) any sale or transfer of Shares
to the Corporation; (iv) any underwritten public offering of Common Stock
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act"); and (v) with respect to sales or other
transfers of up to an aggregate of the following number of Shares (as adjusted
to reflect any stock split, stock dividend, combination of shares or other
similar transaction), but subject in any case to the restrictions set forth in
Section 8:  (A) in the case of each of Koster and Masterson, 130,000 Shares; and
(B) in the case of Patterson, 50,000 Shares;

         (b) In the event of any sale or transfer described in clauses (i) or
(ii) of Section 7(a), the transferee of the Shares shall hold the Shares so
acquired subject to all the restrictions imposed by this Agreement and shall be
deemed a Founder for all purposes hereof, and as a condition to such transfer,
any such transferee shall, at the request of the Corporation or any Investor,
execute and deliver a written instrument agreeing to be bound by the provisions
of this Agreement.

                                      -5-
<PAGE>

     8.  Consent of the Corporation to Transfer.
         --------------------------------------

         (a) As a condition to selling or otherwise transferring any Shares
proposed to be sold or transferred by a Selling Founder and any Participating
Investor to any Proposed Transferee, other than a sale or transfer described in
clause (iii) or (iv) of Section 7(a), the Selling Founder or Participating
Investor shall have obtained the written consent to such transfer by the Board
of Directors of the Corporation by majority vote at a meeting or by unanimous
consent in lieu of a meeting.  Such consent shall not be unreasonably withheld,
and shall be based on the Board of Directors' determination, after such inquiry
as it deems appropriate, but within thirty days of the date of the Selling
Founder's Notice to the Corporation under Section 3, that the Proposed
Transferee is not a competitor of the Corporation and is not otherwise an
inappropriate investor in the Corporation.  In the event the Selling Founder
disagrees with such determination, and the Board of Directors and the Selling
Founder are unable to resolve the disagreement, an independent third party
selected and agreed upon by the Board of Directors and the Selling Founder shall
arbitrate and finally resolve the disagreement.

         (b) As a condition to selling or otherwise transferring 50,000 or more
Shares proposed to be sold or transferred by a Selling Investor to any Proposed
Transferee, the Selling Investor shall have obtained the consent, by majority
vote at a meeting or by unanimous written consent in lieu of a meeting, of the
Board of Directors of the Corporation.  Such consent shall not be unreasonably
withheld, and shall be based on the Board of Directors' determination, after
such inquiry as it deems appropriate, but within ten (10) business days of the
date of the Selling Investor' s Notice to the Corporation under Section 3, that
the Proposed Transferee is not a competitor of the Corporation.  In the event
the Selling Investor disagrees with such determination, and the Board of
Directors and the Selling Investor are unable to resolve the disagreement, an
independent third party selected and agreed upon by the Board of Directors and
the Selling Investor shall arbitrate and finally resolve the disagreement.

         (c) Notwithstanding the foregoing, Section 8(b) shall not apply to any
Investor's sale or transfer of Shares to any Affiliate of such Investor.  For
such purpose, an "Affiliate" of any Investor means any general or limited
partner of such Investor if it is a partnership, or any person that, directly or
indirectly, through one or more intermediaries, controls, or is controlled by,
or is under common control with, such Investor.  In addition, for such purpose,
in the case of any Investor that is a limited partnership for which TVM Techno
Venture Management Limited Partnership, TVM Techno Venture Management III GmbH
or any of their respective Affiliates serves as general partner, the term
"Affiliate" shall include KBL Founder Ventures SCA, KB Lux Venture Capital Fund-
- -European Biotechnology and their respective Affiliates and Alpinvest
International B.V. and its Affiliates.

     9.  Corporation's Option to Purchase Shares of Selling Investor.
         -----------------------------------------------------------

         (a) If the Board of Directors determines that the Proposed Transferee
of a Selling Investor is a competitor of the Corporation, the Corporation shall
have the option to purchase all, but not less than all, of the Offered Shares
for the consideration per Share and on the terms and conditions specified in the
Selling Investor's Notice.  The Corporation must exercise such option, no later
than ten (10) business days after such Selling Investor's Notice is deemed to
have been delivered to it, by written notice to the Selling Investor.

                                      -6-
<PAGE>

         (b) In the event the Corporation does not exercise its option within
such ten-business-day period with respect to all of the Offered Shares, the
Selling Investor shall be entitled to sell to the Proposed Transferee, according
to the terms set forth in the Selling Investor's Notice, the Offered Shares.

         (c) In the event the Corporation duly exercises its option to purchase
all of the Offered Shares, the closing of such purchase shall take place at the
offices of the Corporation no later than ten (10) business days after the notice
by the Corporation to exercise its option is deemed to have been delivered to
the Selling Investor.

         (d) To the extent that the consideration proposed to be paid by the
Proposed Transferee for the Offered Shares consists of property other than cash
or a promissory note, the consideration required to be paid by the Corporation
exercising its option under this Section 9, may consist of cash equal to the
value of such property, as determined in good faith by agreement of the Selling
Investor and the Corporation.

     10.  Lock-up.  Each Founder agrees that upon the request of the Corporation
          -------
or the underwriters managing an underwritten offering of the Corporation's
securities, such Founder will not sell, make any short sale or loan of, grant
any option for the purchase of, or otherwise dispose of any Shares held by him
without the prior written consent of the Corporation or such underwriters, as
the case may be, for a period of up to 180 days from effective date of the
applicable registration statement.

     11.  Sale or Transfer in Violation of this Agreement.  If any sale or other
          -----------------------------------------------
transfer of Shares is made or attempted in violation of any provision of this
Agreement, or if any Shares are not offered to the Corporation or the Investors
as required hereby, the Corporation and the Investors, as the case may be, shall
have the right to purchase such Shares from the owner thereof or his transferee
at any time before or after the transfer, as herein provided.  In addition to
any other legal or equitable remedies which it or they may have, the Corporation
and the Investors may enforce their respective rights hereunder by actions for
specific performance (to the extent permitted by law).  The Corporation shall
not be required (i) to transfer on its books any Shares or other Stock which has
been sold or transferred in violation of any provision of this Agreement or (ii)
to treat as the owner of such Shares or Stock, or to pay dividends to, any
transferee to whom any such Shares or Stock have been so sold or transferred.
If a Founder becomes obligated to sell any Shares to the Corporation under this
Agreement and fails to deliver such Shares in accordance with the terms of this
Agreement, the Corporation may, at its option, in addition to all other remedies
it may have, send to such Founder the purchase price for such Shares as is
herein specified and cancel on its books the certificate or certificates
representing the Shares to be sold. Thereafter, all of the Founder's rights in
and to such Shares shall terminate.

     12.  Disposition of Shares.  Any Shares that the Corporation elects to
          ---------------------
purchase hereunder may be disposed of by it in such manner as it deems
appropriate with or without restrictions on the transfer thereof, and the
Corporation may require their transfer to a nominee or designee as part of any
purchase of the Shares from the Founders.

     13.  Restrictive Legend.  All certificates representing Shares held by the
          ------------------
Founders or Investors which are subject to this Agreement shall have affixed
thereto a legend in substantially

                                      -7-
<PAGE>

the following form, in addition to any other legends that may be required by the
Corporation in connection with compliance with federal or state securities laws
or otherwise:

"The shares of stock represented by this certificate are subject to restrictions
on transfer and/or an option to purchase set forth in a Stock Restriction
Agreement between the Corporation and the registered owner of the shares
represented by this certificate (or his predecessor in interest).  The
Corporation will furnish a copy of such agreement to the holder of this
certificate upon written request without charge."

The Founders and Investors shall cause such legend to be affixed to any of such
certificates not so legended.

     14.  Term.  This Agreement shall terminate upon the closing of a firm
          ----
commitment underwritten public offering of Common Stock pursuant to an effective
registration statement under the Securities Act in which (i) the public offering
price per share is not less than $10.00 (appropriately  adjusted to take account
of any stock split, stock dividend, combination of shares or similar event) and
(ii) the aggregate gross proceeds to the Corporation are not less than
$20,000,000.

     15.  Specific Enforcement.  Each Investor and Founder expressly agrees that
          --------------------
a violation of this Agreement by such Investor or Founder could not be
adequately compensated by money damages alone and that the Investors and the
Corporation will be irreparably damaged if this Agreement is not specifically
enforced.  Upon a breach or threatened breach of the terms, covenants and/or
conditions of this Agreement by any Investor or Founder, the other Investors and
the Corporation shall, in addition to all other remedies, each be entitled to a
temporary or permanent injunction, and/or a decree for specific performance, in
accordance with the provisions hereof.

     16.  Other Agreements.  The restrictions on the Founders' right to dispose
          ----------------
of their Shares pursuant to this Agreement are in addition to and to be
construed consistently with the Founders' rights and obligations (including
restrictions on the Founders' right to dispose of shares of the Corporation's
capital stock) contained in any other agreement relating to restrictions on the
transferability of such Shares that the Founders execute before, on, or after
the date hereof; provided, that this Agreement shall amend and restate the Stock
Restriction Agreement dated as of May 8, 1997, as amended as of January 12,
1998, among the Corporation, the Founders, the Series B Investors and the Series
C Investors, which shall no longer be of any force or effect.

     17.  Waiver, Modification and Termination.  No provision of this Agreement
          ------------------------------------
shall be deemed to have been waived by the Corporation or any Investor in the
absence of a written agreement executed by such party with respect to such
waiver.  This Agreement may be modified or terminated only with the written
consent of the Founders, the Corporation, and the holders of two-thirds in
voting power of the Shares then held by the Investors.

     18.  Accession.  Any Additional Investors as defined in the Purchase
          ---------
Agreement shall automatically become an Investor hereunder by delivering to the
Corporation a written instrument in the form of Exhibit A hereto, by which such

Agreement, whereupon such Additional Investor

                                      -8-
<PAGE>

deemed an "Investor" for all purposes of this Agreement.

     19.  Binding Effect; Assignment.  This Agreement shall be binding upon the
          --------------------------
parties hereto and their heirs, legal representatives, successors and assigns.
The rights and obligations of the Founders and Investors hereunder may not be
assigned or delegated without the written consent of the Corporation.

     20.  Notices.  All notices, requests, consents, deliveries and other

recognized express courier service, to the Corporation at its principal place of
business, and to the Investors and the Founders at their respective last known
address or at their respective address, if any, appearing on the books of the
Corporation.

     21.  Severability.  If any provision of this Agreement shall be held to be
          ------------
illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

     22.  Governing Law.  This Agreement shall be governed by, and construed and
          -------------
enforced in accordance with, the substantive law of the State of California,

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

     TBG has provided DM 1 million silent partnership financing to Sequenom
     Germany, which matches DM 1 million of capital invested in Sequenom Germany
     by the Corporation.  The terms of the silent partnership arrangement are as
     follows:

     .  25% of the amount loaned is due at the end of the investment period.
        The profit shares described above, if any, are applied toward this
        additional payment. The TBG may elect to forego such payments in certain
        situations.

     Principal payment due on December 31, 2005

     This agreement has no "downside protection," which is contained in the 1995
     agreement.

2.  The December 1995 "BJTU" Agreement
    ----------------------------------

     TBG has provided DM 3 million silent partnership financing to Sequenom

     Germany, TBG will pay to the Inc. 50% of the amount of the silent
     partnership.

     Interest rate of 6% of Sequenom GmbH's annual profits.

     The loan may be converted to Common Stock each June or December at the
     option of the bank.  The conversion ratio is calculated as the arithmetic
     mean between $3.15 per share and the current valuation of the Common Stock
     at the time of conversion, not to exceed $8.40 per share.

     The loan must be repaid by December 31, 2007, if not previously converted.
<PAGE>

5.   The February 1998 "BJTU" Agreement
     ----------------------------------

     In February 1998, a German bank purchased 2,700 shares or approximately 5%
     of Sequenom GmbH common stock for DM 3 million (approximately $1,714,000).
     These shares can be converted to Sequenom, Inc.'s Series C Preferred Stock
     at the option of the bank.  The conversion price is $3.15 per share.
     Sequenom, Inc. can call for conversion in the case of an initial public
     offering or the exit of existing investors.

Description of the grant programs for which Sequenom Germany has received
approvals:

1.   Grant from the "Biotechnology 2000" grant scheme from the Ministry of
     Research and Technology ("BMBF"):

     The BMBF has approved a grant (which is a non-repayable contribution) in
     the amount of DM 2.2 million based on the application for the financing of
     a total research and development project of DM 4.4 million.  The grant
     coverage is therefore 50% of total estimated project cost.  The company
     will call the money quarterly in arrears based on actual cost attributable
     to the project.  The project started on September 1, 1995 and has a
     duration of three years.

2.  Grant from Freie und Hansestadt Hamburg (City of Hamburg):

     The City of Hamburg has approved a grant of DM 800,000 based on a list of
     equipment for Sequenom's laboratory to be purchased after September 1,
     1995.  Total expected cash outflows for the equipment purchases is DM 1.6
     million.  Grant coverage is also 50% of estimated cost.

Both grants do not have to be repaid.

Republic of Germany without regard to the conflicts of laws provisions therein.
In any action to enforce this Agreement the prevailing party will be entitled to
costs and attorneys' fees. In the event that any of the provisions of this

to be unenforceable, such provisions shall be limited or eliminated to the
minimum extent necessary so that this Agreement shall otherwise remain in full
force and effect and enforceable.

     9.   Entire Agreement. This Agreement constitutes the entire agreement
          ----------------
between the parties pertaining to the subject matter hereof, and any and all
written or oral agreements previously existing between the parties are expressly
cancelled. Any modifications of this Agreement must be in writing and signed by
both parties.

     10.  Equitable Relief. Recipient acknowledges and agrees that due to the
          ----------------

remedy at law for any breach of its obligations hereunder, that any such breach
may allow Recipient or third parties to unfairly compete with Company resulting
in irreparable harm to Company, and therefore, that upon any such breach or
threat thereof, Company shall be entitled to injunctions and other appropriate
equitable relief in addition to whatever remedies it may have at law.

     11.  Termination. This Agreement may be terminated (1) by Company without
          -----------
cause with twenty-one (21) days' written notice to the Recipient at the address

at the Recipient's facility. Company and Recipient will enter into good faith
discussions sixty (60) days prior to the termination of the Beta Site Agreement
to negotiate a full DNA MassArray(TM) license Agreement. If no full license
Agreement has been established upon termination, the license granted hereunder
shall terminate and Recipient shall immediately return the Evaluation Item,
together with any and all documents, notes and other materials regarding the
Evaluation Item to Company, including, without limitation, all Proprietary
Information and all copies and extracts of the foregoing, but the terms of this
Agreement will otherwise remain in effect.

     12.  PUBLIC ANNOUNCEMENTS. Any announcements or similar publicity with
respect tthe execution of this Agreement shall be agreed upon between the
Parties in advance of such announcement, with such approval not unreasonable
withheld. Both Parties understand that this Agreement is likely to be of
interest to investors, analysts and others, and that the Parties therefore may

is required by law or regulation, will make reasonable efforts to minimize such
disclosure and obtain confidential treatment for any such information which is
disclosed to a governmental agency or group. Each Party agrees to



                                    Page 4
<PAGE>

provide to the other Parties a copy of any public announcement as soon as
reasonably practicable under the circumstances prior to its scheduled release.
Except under extraordinary circumstances, each Party shall provide the other
with an advance copy of any press release at least five (5) business days prior
to the scheduled disclosure. Each Party shall have the right to expeditiously
review and recommend changes to any announcement regarding this Agreement or the
subject matter of this Agreement. Except as otherwise required by law, the Party
whose press release has been reviewed shall remove any information the reviewing
Party reasonably deems to be inappropriate for disclosure.

action to enforce this Agreement the prevailing party will be entitled to costs
and attorneys' fees. In the event that any of the provisions of this Agreement
shall be held by a court or other tribunal of competent jurisdiction to be

respect to the execution of this Agreement shall be agreed upon between the
Parties in advance of such announcement, with such approval not unreasonable
withheld. Both Parties understand that this Agreement is likely to be of

make such public announcements with respect thereto. The Parties agree that any
such announcement will not contain confidential business or technical
information and, if disclosure of confidential business or technical information
is required by law or regulation, will make reasonable efforts to minimize such
disclosure and obtain confidential treatment for any such information which is
disclosed to a governmental agency or group. Each Party agrees to provide to the
other Parties a copy of any public announcement as soon as reasonably
practicable under the circumstances prior to its scheduled release. Except under
extraordinary circumstances, each Party shall provide the other with an advance
copy of any press release at least five (5) business days prior to the scheduled

whose press release has been reviewed shall remove any information the reviewing
Party reasonably deems to be inappropriate for disclosure.

     13.  PUBLICATION - Recipient shall have the right to publish the results of
the work conducted by University under this Agreement to the extent such results

                         SPONSORED RESEARCH AGREEMENT

This AGREEMENT, effective as of October 1, 1999 (the "Effective Date") and
expiring as of September 30, 2000, is made by and between the TRUSTEES OF BOSTON
UNIVERSITY (hereinafter referred to as "UNIVERSITY") having a principal address
at 881 Commonwealth Avenue, Boston, Massachusetts 02215 and Sequenom, Inc.
(hereinafter referred to as "SPONSOR") a Delaware corporation having its
principal place of business at 11555 Sorrento Valley Road, San Diego, CA 92121.

WHEREAS, the research program contemplated by this Agreement is of mutual
interest and benefit to UNIVERSITY and SPONSOR and will further the
instructional and research objectives of the UNIVERSITY in a manner consistent
with its status as a non-profit, tax-exempt, educational institution,

NOW, THEREFORE, in consideration of the mutual covenants and promises herein
contained, UNIVERSITY and SPONSOR agree as follows:

                              I.  RESEARCH PROGRAM

                         V.  PUBLICATION AND COPYRIGHTS

5.1   UNIVERSITY and its investigators will be free to publicly disclose
      (through journals, lectures, or otherwise) the results of the Research
      Program, provided that UNIVERSITY shall have provided a copy of the
      proposed publication to SPONSOR at least sixty (60) days prior to the
      intended submission of any written publication or any other public
      disclosure to allow SPONSOR to determine whether any patentable invention,
      trade secret or Confidential Information (Confidential Information as
      defined in the Confidential Disclosure Agreement set forth in Exhibit C)
      would be disclosed.

      If the proposed disclosure contains a trade secret or Confidential
      Information, UNIVERSITY shall remove or cause the author to remove such
      trade secret or Confidential Information prior to its submission for
      publication or other public disclosure. If the proposed disclosure would
      disclose a patentable or potentially patentable invention, UNIVERSITY
      shall, at the request of SPONSOR, delay or cause the author to delay
      submission of the work for publication or other public disclosure for up
      to an additional sixty (60) days to enable UNIVERSITY or SPONSOR to file a
      patent application.

5.2   Title to any copyrights or copyrightable material produced or composed in
      the performance of the Research Program shall remain with UNIVERSITY;
      provided however, that UNIVERSITY shall grant to SPONSOR an irrevocable,
      royalty-free, nontransferable, non-exclusive right to reproduce, translate
      and use all such copyrightable material; except that such right with
      respect to computer software and its programming documentation is
      applicable only to computer software and its programming documentation, if
      any, that is specified to be developed and delivered under the Research
      Program Scope of Work, Exhibit A. UNIVERSITY shall not assign or license
      its rights under such copyrights or copyrightable material without the
      prior written consent of SPONSOR.

            VI.  CONFIDENTIAL AND PROPRIETARY INFORMATION/MATERIALS

6.1   SPONSOR may wish, from time to time, in connection with work contemplated
      under this Agreement, to disclose Confidential Information (including
      trade secrets) to UNIVERSITY personnel. To protect the confidentiality of
      such information, SPONSOR will request the Principal Investigator and
      other research personnel to sign confidentiality agreements with SPONSOR,
      in a form the same as or similar to Exhibit C hereto.

6.2   In addition, from time to time, SPONSOR may provide UNIVERSITY personnel
      Program Materials for use in the Research Program; such Program Materials
      shall be proprietary to SPONSOR if they were developed prior to or outside
      the performance of this Agreement. SPONSOR may request the Principal
      Investigator and other research personnel to execute materials transfer
      agreements

                                       3
<PAGE>

      with SPONSOR that set forth the proprietary nature of such Program
      Materials and restrictions on their use and disclosure by UNIVERSITY.

                                VII.  PUBLICITY

7.1   Neither party shall use the name of the other party or of any investigator
      or research personnel in any advertising or promotional material without
      the prior written approval of the other, except that SPONSOR shall have
      the right to indentify UNIVERSITY and to disclose the terms of this
      Agreement in any prospectus, offering memorandum, or other document or
      filing required by applicable securities laws or other applicable law or
      regulation. SPONSOR may, and UNIVERSITY shall, however, acknowledge
      SPONSOR's support for the investigations being pursued under this
      Agreement. In any such statements, the relationship of the parties shall
      be accurately and appropriately described.

                         VIII.  INVENTIONS AND PATENTS

8.1   (a)  Sponsor Inventions.  SPONSOR shall own all rights in any inventions
           ------------------
           discovered or conceived solely by its employees or consultants and
           reduced to practice in the course of the Research Program without
           significant use of UNIVERSITY facilities or equipment ("Sponsor
           Inventions").

      (b)  University Inventions.  UNIVERSITY shall own all rights in any
           ---------------------
           inventions discovered or conceived solely by its employees in the
           course of the Research Program ("University Inventions").

      (c)  Joint Inventions.  SPONSOR and UNIVERSITY shall jointly own rights in
           ----------------
           any inventions discovered or conceived jointly by an employee or
           consultant of SPONSOR and an employee of UNIVERSITY; further, SPONSOR
           and UNIVERSITY shall jointly own rights in any inventions discovered
           or conceived solely by SPONSOR's employees or consultants and reduced
           to practice in the course of the Research Program with significant
           use of UNIVERSITY facilities or equipment ("Joint Inventions").

      For the purposes of this Section 8.1, the term "significant use" shall
      have the meaning set forth in the Boston University Patent Policy, Charles
      River Campus (as amended, 11/12/91), a copy of which is attached as
      Exhibit D. The term "inventions" shall include all discoveries (whether or
      not patentable) that are discovered, conceived, or reduced to practice in
      the course of the Research Program funded by SPONSOR, including but not
      limited to processes, methods, formulae, and techniques.

8.2   (a)  UNIVERSITY shall make prompt written disclosure to SPONSOR of any
           University Inventions or Joint Inventions conceived, realized,
           developed,

                                       4
<PAGE>

           or reduced to practice during the course of the Research Program.
           Such written disclosure shall be provided no later than thirty (30)
           days from the date of such conception, realization, development, or
           reduction to practice.

      (b)  Upon such written disclosure, SPONSOR shall have the right, at
           SPONSOR's request and expense, to have UNIVERSITY file the necessary
           papers for obtaining patent protection in any and all countries of
           the world which SPONSOR, in its sole judgment, determines are of
           sufficient interest to merit such filing.

      (c)  Patent applications relating to a University Invention shall be
           filed, prosecuted and maintained by UNIVERSITY in its name, using
           patent counsel reasonably acceptable to SPONSOR.

      (d)  Patent applications relating to a Joint Invention shall be filed,
           prosecuted and maintained by SPONSOR using patent counsel reasonably
           acceptable to UNIVERSITY.

      (e)  Patent applications relating to a Sponsor Invention shall be filed,
           prosecuted and maintained by SPONSOR using patent counsel reasonably
           acceptable to UNIVERSITY.

      (f)  Regarding patent applications under 8.2(c), 8.2(d) and 8.2(e), both
           parties shall have the right to review and comment upon applications
           and correspondence with the Patent Office and shall be provided with
           drafts thereof sufficiently in advance to reasonably allow for such
           review and comment.

      (g)  UNIVERSITY agrees that it will cause to be signed by concerned
           UNIVERSITY personnel all documents of assignment or other documents
           necessary to obtain patent protection as set forth above, and that
           UNIVERSITY will do whatever SPONSOR reasonably requests to obtain and
           maintain such patent rights, at the expense of SPONSOR.

      (h)  If SPONSOR elects not to have a patent application filed in any
           country with respect to a particular University Invention or Joint
           Invention, SPONSOR shall advise UNIVERSITY of such fact at least
           ninety (90) days prior to any deadline for making such election.
           UNIVERSITY may then, at its own expense, file and prosecute such
           patent application, and such patent application and any patents
           issuing therefrom shall not be included within the license option
           granted to SPONSOR pursuant to section 8.3 of this Agreement, and
           UNIVERSITY shall be free to license its rights in such patent to any
           party.

8.3   (a)  UNIVERSITY hereby grants SPONSOR a first option to acquire a royalty
           bearing, exclusive, worldwide license, including the right to
           sublicense, to

                                       5
<PAGE>

           make, have made, use, lease, sell, and offer for sale, products and
           methods embodying or produced through the use of any University
           Invention or Joint Invention. Said right must be exercised by written
           notice to UNIVERSITY within ninety (90) days after receiving from
           UNIVERSITY written disclosure of any University Inventions or Joint
           Inventions as set forth in section 8.2(a).

      (b)  If SPONSOR elects to exercise any of its rights to acquire an
           exclusive license under section 8.3(a) above, both parties agree that
           the PATENT AND KNOW-HOW LICENSE AGREEMENT executed by the parties and
           dated June 1, 1996 (attached hereto as Exhibit E) provides the
           license terms for and will govern any exclusive license rights that
           are elected and exercised pursuant to section 8.3(a). SPONSOR will
           provide written notice to UNIVERSITY of its election of any rights
           under this Agreement. For University Inventions or Joint Inventions
           that SPONSOR does not elect to exercise its option rights to,
           UNIVERSITY shall be free to license that particular invention to a
           third party; provided however, that UNIVERSITY shall not grant any
           rights in such invention on terms which, when taken in total, are
           materially more favorable to the third party than those last offered
           to SPONSOR by UNIVERSITY without first offering SPONSOR the
           opportunity, for ninety (90) days from the date of any offer to a
           third party, to meet the terms of such offer. If SPONSOR fails to
           notify UNIVERSITY in writing within such ninety-day period that it
           has accepted such terms, SPONSOR shall be deemed to have rejected the
           offer, and UNIVERSITY may license its rights in such invention to
           other parties. If SPONSOR notifies UNIVERSITY within such ninety-day
           period that it accepts such offer, UNIVERSITY shall be deemed to have
           entered into a binding license agreement with respect to such terms.

8.4   UNIVERSITY hereby grants SPONSOR a non-exclusive, world-wide, royalty-
      free, perpetual license to use any results of the Research Program
      (including without limitation all discoveries, data, Program Materials,
      and University Inventions and Joint Inventions not exclusively licensed to
      SPONSOR under section 8.3) for research purposes.

                                IX.  LIABILITY

9.1   SPONSOR shall defend, indemnify and hold harmless UNIVERSITY, and its
      trustees, officers, employees and agents and their respective successors,
      heirs and assigns (the "Indemnitees"), against any and all liability,
      damage, loss or expense (including reasonable attorneys' fees and expenses
      of litigation) that may be incurred by or imposed upon Indemnitees, or any
      of them, in connection with any claim, suit, demand, action or judgment
      arising out of the design, production, manufacture, sale, use in commerce,
      lease or promotion by SPONSOR or by an Affiliate or sublicensee of
      SPONSOR, of any product, process or service relating

                                       6
<PAGE>

      to or developed pursuant to this Agreement as long as such liability,
      damage, loss, or expense, is not attributable to the willful misconduct of
      the Indemnitees.

9.2   UNIVERSITY makes no warranties, express or implied, including, without
      limitation, the condition of the research or any inventions or products
      whether tangible, conceived, discovered, or developed under this
      Agreement, and makes no warranties, express or implied, regarding
      merchantability, or fitness for a particular purpose of the research, any
      inventions, and any products under this Agreement. UNIVERSITY shall not be
      liable for any direct, consequential, or other damages suffered by
      SPONSOR, or any licensee of SPONSOR, or any others resulting from the use
      of the research or any invention or product.

                           X.  INDEPENDENT CONTRACTOR

10.1  For the purpose of this Agreement and all services to be provided
      hereunder, the parties shall be, and shall be deemed to be, independent
      contractors and not agents or employees of the other party. Neither party
      shall have authority to make any statements, representations or
      commitments of any kind, or to take any action which shall be binding on
      the other party, except as may be explicitly provided for herein or
      authorized in writing.

                           XI.  TERM AND TERMINATION

11.1  Performance may be terminated by UNIVERSITY immediately upon written
      notice to SPONSOR if circumstances beyond its control preclude
      continuation of the Research Program. SPONSOR may terminate this Agreement
      for any reason upon ninety (90) days written notice to UNIVERSITY.

11.2  In the event that either party shall be in default of any of its
      obligations under this Agreement and shall fail to remedy such default
      within sixty (60) days after receipt of written notice thereof, the party
      not in default shall have the option of terminating this Agreement by
      giving written notice thereof.

11.3  Termination or cancellation of this Agreement shall not affect the rights
      and obligations of the parties accrued prior to termination. Upon any
      termination hereof, UNIVERSITY shall be entitled to be compensated for all
      reasonable expenses and uncancellable commitments incurred as of the
      effective date of termination, not to exceed the total contract amount
      stated in section 3.1 above.

11.4  Articles V, VI, VII, VIII, and IX and Sections 3.1 (the obligation for a
      final accounting and refund), 3.2, 4.1 (the obligation for a final
      report), 11.3, and 11.4, shall survive such termination.

                         RESEARCH PROGRAM SCOPE OF WORK

The Charles R. Cantor research group at the Center for Advanced Biotechnology
(CAB) at Boston University ("UNIVERSITY") will investigate optimizations of mass
spectrometry (MS) based analysis of nucleic acids.  The work will focus
primarily on development of methods for detection of mutations and/or single
nucleotide polymorphisms (SNPs) and de novo DNA sequencing; additional
investigations will be made to determine the feasibility of MS-based
quantitative measurement of genetic expression.

The work will be comprised of both laboratory and computational investigations,
with a special emphasis on techniques and assays that can be adapted for use in
the large-scale automated processes utilized by Sequenom ("SPONSOR").

The following activities will be accomplished under this work plan:

1)  Provide SPONSOR with potential assays for large-scale MS-based
    SNP/polymorphism detection. These assays will be simulated and compared with
    experimentally derived data generated in proof of principle experiments at
    CAB.

2)  Provide SPONSOR with potential assays for MS-based diagnostic detection of
    SNPs, polymorphisms, and de novo DNA sequencing. The assays will be
    simulated and compared with experimentally derived data generated in proof
    of principle experiments at CAB.

3)  Provide SPONSOR with novel methods for capture of nucleic acid samples prior
    to analysis by MS. Potential methods to be investigated include positional
    sequencing by hybridization (PSBH) arrays, and ligation mediated SNP
    detection arrays.

                                 PATENT POLICY


<PAGE>

Boston University Patent Policy

CHARLES RIVER CAMPUS

_____________________________________________________________________________

PREAMBLE
The patent policy outlined herein is the Policy of the Trustees of Boston
University (the "University").  The University recognizes that patentable
inventions may be made in the course of research sponsored by the University
and/or by others through the University.  It is the policy of the University to
maximize the benefits to the individual who makes such patentable inventions, to
the University and to the general public, and thus to stimulate initiative in
the faculty, staff, and employees of the University.  The University recognizes
that this may best be accomplished through patenting and licensing such
inventions in a manner consistent with the public interest, and for such purpose
the University hereby establishes the patent policy set forth herein.  This
Policy supersedes all prior patent policies and amendments thereto applicable to
the Charles River Campus.

1.   PATENT POLICY

     A.  In order to protect the public good and the University, and in order to
fulfill obligations to research sponsors, the University shall claim equity in
all discoveries and its right to acquire the title to and control of such
discoveries where the discoveries are made by faculty, staff, employees, or
students (including all types of trainees or postgraduate fellows) working on or
arising from programs supported in whole or in part by funds, space, personnel,
or facilities provided by the University.


     B.  When a discovery is made by an inventor outside of any program
conducted by the University, and the inventor can demonstrate that the
University did not provide or administer significant funds, space, personnel, or
facilities for work leading to the discovery, the discovery shall remain the
exclusive property of the inventor or his/her sponsor.  The University shall not
ordinarily consider provision of office, classroom, or library facilities as
constituting significant use of University funds, space, personnel or
facilities.  For purposes of this Policy, the term "Investor" shall include all
individuals who participated in and signed a disclosure statement respecting a
discovery or invention.

     C.  When necessary, the University Committee on Inventions and Discoveries
("Committee") shall decide whether an invention or discovery should be
classified under Paragraph A or Paragraph 3 of this Paragraph 1.  Persons or
entities claiming a right to receive royalty interests under the provisions of
Paragraph 4 may appeal the decision of the Committee to the President of the
University.  The President shall recommend final action to the Trustees, whose
decision shall be final.

2.   ROYALTIES

Where the University is entitled to equity in a discovery, the Inventor shall
receive 30 percent of the net royalties accruing therefrom unless the University
recommends a lesser share, which shall not be less than 15 percent based upon
relevant circumstances relating to the discovery.  In the

<PAGE>

event that the University determines that such lesser share is appropriate, the
University shall in its sole discretion designate the recipient or recipients of
the percentage share by which the Investor's share has been reduced. The
Community Technology Foundation (CTF) of Boston University, exclusive agent for
the administration of patents or discoveries made within the University, shall
receive 45 percent of the net royalties (see Paragraph 4). The remaining
royalties from, and equities in the Invention shall be distributed to the School
of the Investor, or in the absence of a School's being involved, the primary
unit or entity of the University with which the Investor works or is affiliated.
Net royalties are defined as gross royalties less amounts granted by the
University specifically for the invention or discovery process, and the cost of
securing, protecting, preserving, and maintaining patents, and of licensing and
marketing of the patent rights, or other costs or fees directly attributable to
the inventions being licensed.

3.   DISCLOSURES

Because the securing of rights in discoveries and inventions depends on prompt
and efficient patent application and administration, all faculty, staff,
students, and employees of the University who make inventions or discoveries
shall immediately disclose said inventions or discoveries to the CTF Patent
Administrator and to the Investor's supervisor.  This disclosure obligation
shall apply to all inventions and discoveries, without regard to whether they
fail under Paragraph A or 3 above.

4.   PATENT ADMINISTRATION

CTF shall be the exclusive agent of the University for the administration of
inventions and discoveries made within the University and covered under
Paragraph 1.A.  CTF shall present the disclosures to the Committee.  Such report
shall state whether CTF has determined that an invention or discovery will be
developed by the University.  The Committee shall consist of eleven voting
members, at least a majority of whom shall be faculty members from the Schools
and Colleges of the University.  The members of the Committee and the Chairman
of the Committee shall be designated by the President of the University.  CTF
shall render a written semiannual report to the Chairman of the Committee on the
disposition and status of all inventions and discoveries submitted.  CTF shall
as promptly as practicable determine whether an invention or discovery shall be
pursued by the University.  If the Committee determines that CTF has not filed a
patent application within one year after it has received a disclosure in respect
of which the University is entitled to claim an interest, the Committee, in
consultation with the Inventor, shall determine what other disposition, if any,
shall be made of the invention or discovery and of its development.

5.   COVERAGE

The Policy shall cover only discoveries and inventions that are patentable as
the term is defined in the United States Code, as amended, or the laws of other
countries where applications are filed.

6.   TRUSTEE REVIEW

<PAGE>

Any disputes that arise under this Policy that are not resolved by the Committee
shall be referred to the President of the University, who shall recommend final
action to the Trustees.  The decision of the Trustees shall be final with
respect to all disputes.

7.   EMPLOYMENT AGREEMENTS

Rights and obligations under this Policy shall survive any termination of
enrollment or employment at the University.

     Nothing herein contained is intended to grant or dispose of any right,
title, and interest to any disclosure, idea, improvement, or invention, whether
patentable or not, which has been supported or funded by outside parties who
acquire rights to such disclosure, ideas, improvements, and invention.

7.   CONSULTING AGREEMENTS

The rights of the University under this policy, and the interests of sponsors
under research grants or contracts, may not be abrogated or limited by
consulting agreements or other contracts entered into between University
students or employees and outside organizations or employers.  University
students and employees should inform outside employers of their obligations and
commitments to the University under this policy.  Such students and employees
should ascertain that patent clauses in their agreements are not in conflict
with their obligations to the University or this Policy statement.  Each student
and employee should make his/her obligations to the University clear to those
with whom such agreements may be made, and should ensure that they are provided
with a current statement of University policy.  Upon request, the University
will provide a standard clause which may be inserted in a student's or
employee's consulting agreement.  This clause will put third parties on notice
as to the University's rights under this policy with respect to inventions and
discoveries.  In cases of conflict of interest, the University reserves the
ultimate right to determine the final disposition of the rights and interests
involved.


Adopted, as amended, by the Trustees of Boston University, November 12, 1991.


                               PATENT AGREEMENT

I affirm that I have received and have read the Boston University Patent Policy
Charles River Campus.

For and in consideration of the provision by Boston University or support in the
form of funds, space, personnel, facilities instruction, supervision or other
assistance, I hereby accept the aforesaid Patent Policy as determinative of my
rights are (_________) in relation to any discoveries or patentable inventions.

render non-exclusive the license granted under Section 3 of this Agreement,
solely with respect to any particular "subject inventions," as defined in the
Bayh-Dole Act, 35 U.S.C. 201(e) (1980), within the UNIVERSITY Patent Rights, if
and only if: (i) at any time after four (4) years after the Effective Date,
within ninety (90) days after written notice from UNIVERSITY to LICENSEE of
UNIVERSITY's intent to render such license non-exclusive, LICENSEE has not put
the subject inventions into commercial use and is not keeping such subject
inventions reasonably available to the public; (ii) LICENSEE is not demonstrably
engaged in a significant research, development, manufacturing, marketing or
licensing program with respect to such subject inventions; and (iii) such
failure does not result from actions or inactions of any agency whose approval
is required for commercial sales. At any time after seven (7) years after the
Effective Date, UNIVERSITY shall have the right to terminate the license granted
under Section 3 of this Agreement, solely with respect to any such "subject
inventions," if and only if the conditions set forth in sub-paragraphs (ii) and

written notice from UNIVERSITY to LICENSEE of UNIVERSITY's intent to terminate
such license, LICENSEE has not put such subject inventions into commercial use
and is not keeping such subject inventions reasonably available to the public.
If UNIVERSITY elects to terminate such license with respect to particular
subject inventions, the UNIVERSITY shall refund to LICENSEE that portion of the
funds provided to UNIVERSITY by LICENSEE under the Sponsored Research Agreement
that related to the development of such subject

                                                                  -Page 6 of 23-

Products available to the public shall not constitute a ground for UNIVERSITY to
terminate this Agreement under Section 9.4 hereof.

accompanied by a report setting forth the calculation of the amount due. All
monies to be paid to UNIVERSITY shall be made and computed in United States
Dollars, and LICENSEE shall use its best efforts to convert royalties in any
country to United States Dollars; provided, however, that if conversion to and
transfer of Dollars cannot be made by LICENSEE in any country for any reason,
LICENSEE may pay such sums in the currency of the country in which Net Sales are

relate, for the purpose of verifying NET SALES and any royalty due thereon. Such
representative shall disclose to UNIVERSITY only information relating to the
accuracy of the records kept and the payments made, and shall be under a duty to

adjustment in the amount of royalties due the UNIVERSITY on account of
overpayment or underpayment of royalties shall be made at the next date when
royalty payments are to be made to the UNIVERSITY under Section 5.2 herein. If
the verification on behalf of the UNIVERSITY results in an upward adjustment of

otherwise due UNIVERSITY shall not be reduced by more than ***. In addition, and
notwithstanding, the last clause of the preceding sentence, in the event that
the license fees and royalties payable hereunder and to Third Parties on a
Product exceed *** of the Net Sales price of such Product in any jurisdiction or
*** of LICENSEE's Net Income with respect to sublicenses in such jurisdiction,
LICENSEE may reduce any amounts due UNIVERSITY hereunder pro rata with the
license fees and royalties due Third Parties on such Product, to the extent
necessary to reduce the total license fees and royalties for such Product to ***
of the Net Sales price of the Product or *** of LICENSEE'S Net Income in such
jurisdiction.

          (b)  LICENSEE may credit against any amounts due UNIVERSITY under this

treatment request and filed separately with the Commission.

<PAGE>

     5.6  Late Payments. In the event that any payment due hereunder is not
          -------------
made when due, the payment shall accrue interest beginning on due date as herein
specified, calculated at the annual rate of the prime interest rate quoted by
the Bank of Boston on the date said payment is due, the interest being
compounded on the last day of each calendar quarter, provided that in no event
shall said annual rate exceed the maximum legal interest rate in Massachusetts.
The payment of such interest shall not foreclose UNIVERSITY from exercising any
other rights it may have as a consequence of any overdue payment.

                       ARTICLE VI. INFRINGEMENT ACTIONS
                       --------------------------------

          ---------------------------------------
LICENSEE of any infringement in the Territory known to UNIVERSITY of the
UNIVERSITY Patent Rights and shall provide LICENSEE with the available evidence,
if any, of such infringement. LICENSEE, at its sole expense, shall have the
right to determine the appropriate course of action to enforce the UNIVERSITY
Patent Rights or otherwise abate the infringement thereof, to take (or refrain
from taking) appropriate action to enforce the UNIVERSITY Patent Rights, to
control any litigation or other enforcement action and to enter into, or permit,
the settlement of any such litigation or other enforcement action with respect
to the UNIVERSITY Patent Rights, and shall consider, in good faith, the
interests of UNIVERSITY in so doing. The parties may agree to permit UNIVERSITY
to control any such enforcement action. The party controlling any enforcement
action shall not settle the action or otherwise consent to judgment in such
action that adversely affects the rights or interests of the non-controlling
party or imposes additional obligations on the non-controlling party, without
the prior written consent of the non-controlling party. The party controlling
any enforcement action shall pay all expenses associated with such action;
provided, however, that LICENSEE may offset fifty percent (50%) of the expenses
incurred in any such action against any amounts due UNIVERSITY, provided that in
no event shall any payment otherwise due UNIVERSITY be reduced for such purpose
by more than fifty percent (50%). Any recovery obtained in such action shall be
distributed in the following order of precedence: (1) UNIVERSITY will be
reimbursed for any withheld payments, (2) LICENSEE will be reimbursed for its
expenses, (3) UNIVERSITY will be paid a reasonable approximation of its royalty
on lost sales of Products, and (4) LICENSEE will retain any remaining amounts
except with respect to punitive or other exemplary damages, which shall be
distributed seventy percent (70%) to LICENSEE and thirty percent (30%) to
UNIVERSITY.

     6.2  Abandonment of Suit. Should either party commence a suit under these
          -------------------
provisions and thereafter elect to abandon the same, it shall give timely notice
to the other party who, if it so desires, may continue prosecution of such suit;
provided, however, that the sharing of expenses and any recovery in such suit
shall be as agreed upon between the parties.

     6.3  Allegations of Invalidity or Non-Infringement. In the event any claim
          ---------------------------------------------
or action alleging invalidity or non-infringement of any of the UNIVERSITY
Patent Rights is brought against LICENSEE and/or UNIVERSITY, LICENSEE shall have
the right to control the defense and settlement of the action, provided that
payment of the expenses and costs of such action, including attorneys' fees,
shall be borne and reimbursed as set forth in Section 6. 1.

                                                                  -Page 9 of 23-

     6.4  Cooperation. In any infringement suit as either party may institute
          -----------
to enforce the UNIVERSITY Patent Rights pursuant to this Agreement, the other
party hereto agrees, at the request and expense of the party initiating the
suit, to use its best efforts to cooperate, to have its employees testify when
requested and to make available relevant records, papers, information, samples,
specimens, and the like.

     6.5  Consent to Settlement. No settlement or consent judgment or other
          ---------------------
voluntary and final disposition of any suit affecting the UNIVERSITY Patent
Rights may be entered into without the consent of both parties, which consent
shall not be unreasonably withheld. Notwithstanding the foregoing, the party
controlling any suit referred to in this Article VI shall have the right to
settle any claims for infringement upon such terms and conditions that shall be
mutually agreed upon by UNIVERSITY and LICENSEE. During the term of this
Agreement, and upon the consent of UNIVERSITY, LICENSEE shall have the right to
sublicense any alleged infringer under the UNIVERSITY Patent Rights.

           ---------------
harmless UNIVERSITY, and its trustees, officers, employees and agents and their
respective successors, heirs and assigns (the "Indemnitees"), against any and
all liability, damage, loss or expense (including reasonable attorneys' fees and
expenses of litigation) that may be incurred by or imposed upon the Indemnitees,
or any of them, in connection with any Third Party claim, suit, demand, action
or judgment arising out of the following:

          (a)  the design, production, manufacture, sale, use in commerce, lease
or promotion by LICENSEE or by an Affiliate or sublicensee of LICENSEE of any
product, process or service relating to or developed pursuant to this Agreement;
or

          (b)  any other activities of LICENSEE or a sublicensee to be carried
out pursuant to this Agreement.

LICENSEE'S indemnity under (a) shall apply to any liability, damage, loss or
expense whether or not it is attributable to the negligent activities of the
Indemnitees, and "Third-Party" claims under (a) shall be deemed to include
LICENSEE'S cross-claims and Third-Party complaints against Indemnitees arising
out of the matters described in (a) to the extent they are based on Third-Party
claims against LICENSEE arising out of such matters. LICENSEE'S indemnification

of the defense or settlement of any such claim, demand, action or other
proceeding. LICENSEE's indemnity obligations under this article shall not apply
to amounts paid in any settlement if effected without its consent. LICENSEE
shall not settle or consent to an adverse judgment in any such claim, demand,
action or other proceeding that directly affects the rights or interests of any
Indemnitee or imposes additional obligations on such Indemnitee, without the
prior express written consent of such Indemnitee, which consent shall not be
unreasonably withheld or delayed. The Indemnitee, its employees and agents,
shall cooperate fully with LICENSEE and its legal representatives in the
investigation of any action, claim or liability covered by this indemnification.

LICENSEE shall at its sole expense, procure and maintain policies of
comprehensive general liability insurance in amounts not less than $2,000,000
per incident and $2,000,000 in annual aggregate and naming the Indemnitees as
additional insureds. Such comprehensive general liability insurance shall
provide product liability coverage. LICENSEE shall provide UNIVERSITY with
written evidence of such insurance upon request of UNIVERSITY. In the event the
product liability coverage aforesaid is not occurrence liability, LICENSEE shall
maintain such comprehensive general liability insurance for a reasonable period
of not less than five (5) years after it has ceased commercial distribution or
use of any product, process or service relating to, or developed pursuant to,
this Agreement. If LICENSEE is unable to obtain the required amounts of
insurance at commercially reasonable rates, UNIVERSITY will cooperate with
LICENSEE to either obtain a waiver of this provision, assist in identifying a
carrier to provide such insurance, or identify a program for self-insurance or
other alternative measures. This Section 10.4 shall survive the expiration or
termination of this Agreement. Upon request, LICENSEE shall provide UNIVERSITY
with certificates of insurance evidencing its compliance with the insurance
requirements of this Section.

     10.5  Additional Limitations of Liability. Notwithstanding the provisions
           -----------------------------------
Section 2.3, the liability of UNIVERSITY of for any and all breaches of this
Agreement by a party other than UNIVERSITY, and for any and all failures of
Products in the aggregate, shall be limited to five percent (5%) of the
cumulative royalties paid by LICENSEE, and LICENSEE hereby waives and disclaims
the right to recover any damages in excess of such amount for any and all such
breaches and for any and all such failures irrespective of whether such damages
are direct, indirect, consequential, incidental, or any other types of damages
and irrespective of whether based upon loss of investment, loss of production,
lost profits, interest on investment, interruption of business, or any other
loss of any character whatsoever. LICENSEE further agrees that its sole and
exclusive remedy for any and all such breaches and any and all such failures
shall be to recover damages actually sustained up to, and not in excess of, such
amount. The foregoing notwithstanding, nothing in this Agreement shall limit
LICENSEE'S right to seek equitable relief in the event of University's breach of
Article VII or Article II of this Agreement.

     10.6  Limited Liability. In no event shall either party be liable to
           -----------------
the other or any third party for any special, consequential or incidental
damages arising out of or related to this Agreement or with respect to any
claim, demand, action or other proceeding relating to this Agreement however
caused, and on any theory of liability (including negligence), whether or not
the party has been advised of the possibility of such damages.

                          ARTICLE XI.  FORCE MAJEURE
                          --------------------------

     Neither party shall be held liable or responsible to the other party nor be
deemed to have defaulted under or breached the Agreement for failure or delay in
fulfilling or performing any term of this Agreement to the extent, and for so
long as, such failure or delay is caused by or results from causes beyond the
reasonable control of the affected party including but not limited to from,
earthquakes, floods, embargoes, wars, acts of war (whether war is declared or
not),

                                                                 -Page 13 of 23-

           -----
this Agreement may be resolved by a court of competent jurisdiction located in
Boston, Massachusetts.

     12.2  Injunctive Relief.  Each party acknowledges that a breach by the
           -----------------
other party of any provision of this agreement relating to Confidential
Information would cause irreparable harm, that legal damages are not sufficient
to remedy any such breach, and that the sufficiency of legal damages shall not
constitute a ground for opposing any action for equitable relief with respect to
any breach or prospective breach of any such provision.  LICENSEE shall be
entitled to seek equitable relief with respect to the prospective termination of
this Agreement by UNIVERSITY.

Boston University Patent Policy                      [university logo]

CHARLES RIVER CAMPUS
- --------------------------------------------------------------------------------

PREAMBLE

The patent policy outlined herein is the Policy of the Trustees of Boston
University (the "University").  The University recognizes that patentable
inventions may be made in the course of research sponsored by the University
and/or by others through the University.  It is the policy of the University to
- ---
maximize the benefits to the individual who makes such patentable inventions, to
the University and to the general public, and thus to stimulate initiative in
the faculty, staff, and employees of the University.  The University recognizes
that this may best be accomplished through patenting and licensing such
inventions in a manner consistent with the public interest, and for such purpose
the University hereby establishes the patent policy set forth herein.  This
Policy supersedes all prior patent policies and amendments thereto applicable to
the Charles River Campus.

1.  PATENT POLICY

       A. In order to protect the public good and the University, and in order
to fulfill obligations to research sponsors, the University shall claim equity
in all discoveries and its right to acquire the title to and control of such
discoveries where the discoveries are made by faculty, staff, employees, or
students (including all types of trainees or postgraduate fellows) working on or
arising from programs supported in whole or in part by funds, space, personnel,
or facilities provided by the University.

      B.  When a discovery is made by an inventor outside of any program
conducted by the University, and the inventor can demonstrate that the
University did not provide or administer significant funds, space, personnel, or
facilities for work leading to the discovery, the discovery shall remain the
exclusive property of the inventor or his/her sponsor. The University shall not
ordinarily consider provision of office, classroom, or library facilities as
constituting significant use of University funds, space, personnel, or
facilities. For purposes of this Policy, the term "Inventor" shall include all
individuals who participated in and signed a disclosure statement respecting a
discovery or invention.

     C.   When necessary, the University Committee on Inventions and Discoveries
("Committee") shall decide whether an invention or discovery should be
classified under Paragraph A or Paragraph B of this Paragraph 1. Persons or
entities claiming a right to receive royalty interests under the provisions of
Paragraph 4 may appeal the decision of the Committee to the President of the
University. The President shall recommend final action to the Trustees, whose
decision shall be final.

2.  ROYALTIES

Where the University is entitled to equity in a discovery, the Inventor shall
receive 30 percent of the net royalties accruing therefrom unless the University
recommends a lesser share, which shall not be less than 15 percent, based upon
relevant circumstances relating to the discovery.  In the event that the
University determines that such lesser share is appropriate, the University
shall in its sole discretion designate the recipient or recipients of the
percentage share by which the Inventor's share has been reduced.  The Community
Technology Foundation (CTF) of Boston University, exclusive agent for the
administration of patents or discoveries made within the University, shall
receive 45 percent of the net royalties (see Paragraph 4).  The remaining
royalties from, and equities in, the invention shall be distributed to the
School of the Inventor, or in the absence of a School's being involved, the
primary unit or entity of the University with which the inventor works or is
affiliated.  Net royalties are defined as gross royalties less amounts granted
by the University specifically for the invention or discovery process, and the
costs of securing, protecting, preserving, and maintaining patents, and of
licensing and marketing of the patent rights, or other costs or fees directly
attributable to the inventions being licensed.

<PAGE>

3.  DISCLOSURES

Because the securing of rights in discoveries and inventions depends on prompt
and efficient patent application and administration, all faculty, staff,
students, and employees of the University who make inventions or discoveries
shall immediately disclose said inventions or discoveries to the CTF Patent
Administrator and to the Inventor's supervisor.  This disclosure obligation
shall apply to all inventions and discoveries, without regard to whether they
fall under Paragraph A or B above.

4.  PATENT ADMINISTRATION

CTF shall be the exclusive agent of the University for the administration of
inventions and discoveries made within the University and covered under
Paragraph l.A.  CTF shall present the disclosures to the Committee.  Such report
shall state whether CTF has determined that an invention or discovery will be
developed by the University.  The Committee shall consist of eleven voting
members, at least a majority of whom shall be faculty members from the Schools
and Colleges of the University.  The members of the Committee and the Chairman
of the Committee shall be designated by the President of the University. CTF
shall render a written semiannual report to the Chairman of the Committee on the
disposition and status of all inventions and discoveries submitted. CTF shall as
promptly as practicable determine whether an invention or discovery shall be
pursued by the University. If the Committee determines that CTF has not filed a
patent application within one year after it has received a disclosure in respect
of which the University is entitled to claim an interest, the Committee, in
consultation with the Inventor, shall determine what other disposition, if any,
shall be made of the invention or discovery and of its development.

     7.1  Ownership of Inventions. Ownership of Licensed Technology developed
          -----------------------
by individuals providing technical assistance on behalf of UNIVERSITY pursuant
to Section 3.3 of this Agreement shall be governed as if such Licensed
Technology were developed pursuant to the Sponsored Research Agreement.

     7.2  Patent Rights Generally. Control over, and associated expenses for,
          -----------------------
the filing, prosecution, and maintenance of patents and patent applications
relating to inventions licensed hereunder will be allocated according to the
Sponsored Research Agreement. In the event that UNIVERSITY obtains additional
licensees under any invention licensed by LICENSEE, LICENSEE shall pay only its
pro-rata share of patent-related expenses. LICENSEE shall have the right to
cease paying for the filing, prosecution, or maintenance of any patent or patent
application in any country upon thirty (30) days prior written notice to
UNIVERSITY. In such event, LICENSEE will have no further rights under this
Agreement with respect to such patent or patent application in such country, and
LICENSEE agrees to assign to UNIVERSITY any rights LICENSEE may have in such
patent or patent application in such country.

     7.3  Reimbursement of Expenses. LICENSEE shall reimburse UNIVERSITY for
          -------------------------
the reasonable expenses incurred by UNIVERSITY in relation to the filing,
prosecution, and maintenance of patents and patent applications licensed
hereunder; provided, however, that such expenses shall be equally divided among
LICENSEE and any other licensees of the Licensed Technology. Without limiting
the generality of the foregoing, LICENSEE will reimburse UNIVERSITY only one-
third of such expenses with respect to the Curved Field Reflectron Invention.

     7.4  Enforcement of UNIVERSITY Patent Rights.  UNIVERSITY shall notify
          ---------------------------------------
LICENSEE of any infringement in the Territory known to UNIVERSITY of the
Licensed Technology and shall provide LICENSEE with the available evidence, if
any, of such infringement. LICENSEE, at its expense, shall have the right to
determine the appropriate course of action to enforce rights in the Licensed
Technology or otherwise abate the infringement thereof, to take (or refrain from
taking) appropriate action to enforce the rights in

                                       9
<PAGE>

the Licensed Technology, to control any litigation or other enforcement action
and to enter into, or permit, the settlement of any such litigation or other
enforcement action with respect to the Licensing Technology. UNIVERSITY shall
cooperate fully with LICENSEE in connection with such litigation or other
enforcement action and shall furnish to LICENSEE all evidence and assistance in
its control. The proceeds of any monetary judgement, reward or settlement from
such litigation or other enforcement action shall be used first to reimburse
LICENSEE for its expenses. UNIVERSITY will receive a percentage of such proceeds
remaining after deduction of such expenses equal to the running royalty rate set
forth in Section 4.3(a), (b), (c) or (d) most nearly applicable to the activity
in question, and LICENSEE will retain any remaining amounts.

Dear Charles,

It was a pleasure having you at our facility in San Diego.

This letter comprises in principle our intention to move forward on a
renegotiated Research Agreement in return for a "field of use" on related
technology developed in your lab. It includes our budget proposal for the
retroactive period including September 1996 through September 1997 and outlines
the budget for September 1997 through September 1998.

The following budget proposals include consideration of the August 29, 1997 memo
from Matt Barber regarding the lab budgets for 9/96 -  9/97 and 9/97 - 9/98.

1996 - 1997 Budget
- ------------------

Our attached budget proposal for 1996 - 1997 of $112,454 though less than your
budget of $130,903 is a significant increase from our original proposal of
$81,657.  The salary of the lab manager and reduced supplies are the material
items reduced from your proposal.

1997 - 1998 Budget
- ------------------

Budget restraints require us to reduce your 1997 - 1998 budget proposal.  The
major items deleted include reducing Dr. Cantor's time reduced to 20% and
deleting the Lab Manager and grad student.  The supplies and other expenses were
also reduced by 45%.  The adjusted budget total of $219,013 still represents a
major investment over the coming year.

We hope you view this proposal as a significant commitment to continue our
valuable relationship with Boston University.

Best Regards,

/s/ Steve Zaniboni

development, production and distribution of micro-pipettes and nanoliter
plotters for various applications.
Furthermore, GeSIM develops, produces and distributes silicon chips of different
geometry and surface treatments (GeSim chip technology, hereinafter CT).

Sequenom`s field of work is the development and utilization of procedures for
the analyses of bio-polymers using mass spectrometry to separate, detect and
characterize the sample(s) or analysis products. To this end they combine the
chip concept with protected solid phase chemistry and enzymes. Sequenom
distributes the complete automation of this process. One essential step in this
process is the loading of SpectroChips ("SpectroChip" = trademark), which
requires the use of NLT.

In respect of the main area of activity of SEQUENOM, the mass spectrometric
analysis of nucleic acids, the consulting on the part of the Inventor is
exclusive (Annex 1, Consulting Agreement).

    The parties collaborate closely in the area of mass spectrometric analysis
of nucleic acids and other biopolymers in the framework of projects, which may
be supported in part by third parties, among others BNBF. These projects are or
will be at least proportionately financed by SEQUENOM.

(2) Inventions and Proprietary Rights

    The Inventor has made the inventions listed in Annex 2 in the area of MALDI
(Matrix Assisted Laser Desorption/Ionization) (Annex 2 makes no claim to being
complete). Further inventions in the area of mass spectrometric analysis of

<PAGE>

    The granting of licenses for the above-described existing and future patent
rights from the Inventor to SEQUENOM in the area of the above-described
collaboration is governed by the following Agreement.

(S) 1
CONTRACTUAL RIGHTS

(1) Area of work

    The Inventor in his capacity as a consultant to SEQUENOM collaborates
with SEQUENOM both (a) in the area of mass spectrometric analysis of nucleic
acids as well as (b) in the performance of joint research and developmental work
in the area of mass spectrometric high throughput analysis of biopolymers. The
term high throughput analysis may be described in this context among other
things by the following parameters:

    -    routine mass spectrometric measurements of more than 60 single samples
         per hour
and
    -    volume of a single sample of less than 100 nanoliters, applied both
         directly or indirectly to the sample carrier of the mass spectrometer
         by means of miniaturized arrays.

    In respect of the areas of work named under (a) and (b), the Inventor
collaborates with SEQUENOM as the exclusive commercial partner, i.e., licensee,
or together with SEQUENOM and additional partners, on condition that SEQUENOM
agrees to it.

(2) Contractual Rights

    Contractual Rights as defined by this agreement are present and future
patents applied for and/or granted and patentable results according to items a)-
c) of the preamble. The Inventor shall use best efforts to solely own the
intellectual property which was produced on his part under the terms of the
collaboration. In the event of joint inventions of co-workers of the Inventor
which are subject to the Law governing inventions of employees, the Inventor
shall within his sphere of influence see to it that the inventions are claimed
without restrictions and are transferred to SEQUENOM in accordance with the
conditions stipulated herein.

    Patents already applied for or granted under the terms of the collaboration
are listed in Annex 2 (Annex 2 makes no claim to being complete).

(S) 2
CONTRACTUAL KNOW-HOW

    The Inventor has extensive know-how in the technical field of the
Contractual Rights transferred hereby, and the collaboration agreed upon herein,
in particular in the preparation of samples and in the configuration and
operation of instrumentation and the interpretation of mass spectra. This know-
how is of essential importance for the practical implementation of the
Contractual Rights.

                                       2
<PAGE>

(S) 3
GRANTING OF RIGHTS

1.  The Inventor gives SEQUENOM a worldwide exclusive license for the unlimited
use of the Contractual Rights and the Contractual Know-how. The license is
limited to the area of work as defined in (S) 1 (1).

    If it is not possible to grant an exclusive license for the area of work
because of the general conditions (limitations) for the public promotion of
research, or because of other prior written agreements, if applicable, including
third party participants in the project, then the Contractual Rights transferred
shall at least cover the exclusive rights of use for SEQUENOM's essential area
of mass spectrometric high throughput analysis of nucleic acids (as defined
above).

(S) 4
CONTINUED DEVELOPMENT OF CONTRACTUAL RIGHTS

1.  The Inventor shall use best efforts within the scope of his research to
promote the future development of the Contractual Rights and to maintain the
technical lead over alternative developments.  The Inventor does not hereby
assume an obligation to undertake specific research measures (directions) or to
guarantee success.

2.  The Inventor shall include into the contractual relationships all new
developments resulting from his efforts in respect of the Contractual Rights,
the Contractual Know-how and the area of collaboration.  In particular, he shall
maintain the know-how at the latest state of development by regularly updating
the records with research and test results.  SEQUENOM shall have regular access
to the updated records.

(S) 5
GUARANTEE OF THE LICENSOR

    The Inventor/Licensor is not aware of any facts, in particular proprietary
rights, which preclude the use of existing Contractual Rights.  The Inventor,
however, does not assume liability therefor.  The Inventor shall rather
endeavor, together with SEQUENOM, to design around obstacles, if they preclude
the use of the Contractual Rights.

(S) 6
ROYALTIES

1.  For the granting of the described license for the Contractual Rights,
SEQUENOM shall pay to the Inventor a royalty in the amount of     ***     of the
net sales realized by SEQUENOM using the Contractual Rights - independently of
the number of Contractual Rights used. Sales are the proceeds - after receipt of
payment by SEQUENOM - from the sale of

                                       3
<PAGE>

products, which are based on Contractual Rights and/or the application of which
requires the use of the Contractual Rights, or services which are rendered using
the Contractual Rights.

2.  For sales that are realized using exclusively the Contractual Rights, which
result from the collaboration (see (S)1) of SEQUENOM and the Inventor, and in
which the Inventor or one of his co-workers is named as (co-)inventor, the
royalty is      ***    .

3.  In case the sum total of all royalties which SEQUENOM has to pay to third
parties exceeds the value of  ***   for given proceeds, the royalties payable to
the Inventor shall be                         ***              in order to
reduce it to exactly      ***     of the given proceeds.

4.  SEQUENOM refunds all expenses to the Inventor which he has incurred or
incurs in connection with applying for, maintaining and defending patents for
the Contractual Rights, provided that these Contractual Rights are transferred
exclusively to SEQUENOM. Included herein is the cost of applying for,
maintaining and defending patents in other countries. The parties to the
agreement shall discuss the procedures concerning patents matters as required.
If licenses for a given patent or a given patent application are granted to
third parties for areas of application which are not exclusive to SEQUENOM, then
all expenses as described above are shared as a rule proportionately by SEQUENOM
and this (these) third party (parties). Expenses already paid by SEQUENOM shall
be reimbursed proportionately by this (these) third party (parties). The
Inventor is thus obliged to transfer this obligation to possible third party
licensees. The Inventor shall also, by prior agreement, be reimbursed for
expenses which arise in connection with obtaining or reinstatement of patent
right according to Annex 2, paragraph 2.

5.  Royalties are always due at the end of a calendar year and after receipt of
payment for the underlying sales by SEQUENOM.

CONFIDENTIALITY

1.  The parties undertake mutually to keep confidential all information
exchanged or to be exchanged during the duration of this agreement and knowledge
acquired concerning fundamentals, developments, improvements and other details
in respect of the Contractual Rights and the Contractual Know-how as well as
matters regarding the execution of the agreement, even if they have not been
expressly designated as secret or confidential.  This does not apply, if the
disclosure is necessary to transfer the know-how to licensees in other areas of
the agreement or other areas of application, in order to obtain official
approvals, or to disclose the results obtained to the public or to professional
circles.

2.  Both parties undertake to impose this obligation of confidentiality on their
co-workers or employees, who because of their occupation can acquire useful
knowledge of the Contractual Rights and the Contractual Know-how.  This
obligation of confidentiality is to be imposed on the

staff also after termination of their employment contract or assistance
relationship as postgraduates or doctoral candidates.

3.  The Inventor undertakes to impose on other licensees corresponding
obligations for confidentiality in other areas of the agreement or areas of
application.

4.  This obligation of confidentiality continues beyond the duration of the
agreement.  It remains in effect until the know-how becomes public.

5.  The contracting parties shall inform each other in oral or written form
about planned publications which contain information according to (S) 7,
paragraph (1).  A time limit of 3 months shall be provided to the respective
party from the time of complete disclosure to publication for raising an
objection or for applying for relevant proprietary rights.  In case an objection
is raised, the parties shall try to reach a solution which is acceptable to both
sides.  An objection may only be raised or maintained for an important reason.

(S) 8
DURATION OF AGREEMENT

1.  The agreement ends at the end of the tenth calendar year after the first
calendar year for which licenses are paid according to its conditions unless it
is renewed at the latest six months before the end.

2.  Beyond that, the agreement ends automatically, if the royalties from
SEQUENOM to the Inventor are below the amount of DM 10,000.00 in two successive
calendar years. This provision may be applied by both parties at the earliest
three years after signing of the agreement.

3.  In case of termination of the agreement according to paragraph (2), all
rights and obligations concerning the Contractual Rights and the Contractual
Know-how revert back to the Inventor. If the Inventor realizes income from the
continued use of the patents or the know-how of this agreement from other
licensees, SEQUENOM shall receive a *** share but no more than the amount of
patent costs assumed by SEQUENOM.

(S) 9
FINAL PROVISIONS

1.  SEQUENOM has the right to grant sublicenses of the Contractual Rights. In
case of the granting of sublicenses, SEQUENOM shall have the obligation to
ensure that all rights of the Inventor resulting from this agreement are also
applicable to the sublicenses.

2.  The Inventor undertakes to maintain the Contractual Rights including
additional applications and the applications made in the course of the
agreement, as far as they

concern the area of the Contractual Rights or to offer them to SEQUENOM, and not
to assign them to third parties without SEQUENOM's consent.

3.  The agreement is subject to the written form.  Modifications require the
written form.  This is also applicable to this written form clause itself.

4.  Should individual provisions of this agreement be or become invalid or
unenforceable, the validity of the agreement shall otherwise not be affected;
the parties shall undertake to replace the invalid or unenforceable provision by
an effective amendment which comes closest to the commercial purpose of the
invalid or unenforceable provision.

5.  Place of jurisdiction is the residence or principle place of business of the
respective defendant(s) within the Federal Republic of Germany.

        a shipment, Buyer must (i) give notice to Seller of Buyer's intent to
        reject the shipment within ten (10) days of receipt together with a
        detailed written indication of the reasons for such possible rejection,
        and (ii) as promptly as reasonably possible thereafter, provide Seller
        with notice of final rejection and the full basis thereof. After notice
        of intent to reject is given, Buyer shall cooperate with Seller in
        determining whether rejection is necessary or justified. If no such
        notice of intent to reject is timely received, Buyer shall be deemed to
        have accepted such delivery of Product, provided, however, in the case
        of Products having latent defects which upon diligent examination by
        Buyer could not have been discovered, Buyer must give notice of Buyer's
        intent to reject within thirty (30) days after discovery of such
        defects, provided that such notice may in no event be given later than

        entitled to a refund of the purchase price (together with insurance and
        freight charges if applicable) of properly rejected Products at the time
        they are ultimately rejected. Seller shall notify Buyer as promptly as
        reasonable possible whether it accepts Buyer's basis for any rejection.

B.      Whether or not Seller accepts Buyer's basis for rejection, promptly on
        receipt of a notice of rejection, Seller shall use its reasonable
        efforts, at Buyer's request to provide replacement Product which shall
        be purchased by Buyer as provided in this Agreement.

C.      Unless Seller requests the return of the rejected batch within sixty
        (60) days of receipt of buyer's notice of rejection, Buyer shall destroy
        such batch promptly and provide Seller with certification of such
        destruction. Buyer shall, upon receipt of Seller's request for return,
        promptly dispatch said batch to Seller, at Seller's cost.

     thirty (30) days' prior notice to Seller, elect to terminate its
     obligations hereunder to purchase, and Seller's obligations to supply, such
     Product. Notwithstanding the foregoing, Buyer shall have no rights under
     this Section 4.1 (A) if the third-party quote is given in connection with
     or in anticipation of some other relationship with the Buyer.

    3.2  Subject to the provisions of Section 4, on the Effective Date and on
    or before three (3) months prior to the end of an Agreement Year, Sequenom
    will issue a Purchase Order for the number of System Products that Sequenom
    intends to purchase in the coming year.  For each Agreement Year, the
    projected quantity of System Products to be purchased by Sequenom
    ("Projected Quantity") is as follows:

         Year 1    ***  Products
         Year 2    ***  Products
         Year 3    ***  Products

    3.3  To maintain the discount from list price of the Products as set forth
    in Exhibit 2.1, Sequenom must order for delivery in any Agreement Year no
    less than   ***                             ***  of the Projected Quantity
    ("Required Purchases").  If in any Agreement Year Sequenom does not meet its
    quota of Required Purchases, the discount provided Sequenom shall be reduced
    *** *** ***     Such reduction in discount shall remain in effect until such
    time as Sequenom shall have ordered in accordance with the terms of this
    Agreement and released for delivery a sufficient quantity of System Products
    to make up the prior year(s) deficiency(ies) and satisfy the current year's
    pro rata Required Purchases.

    3.4  Notwithstanding the provisions of Section 3.3, and subject to the last
    sentence of this Section 3.4, all Invoices issued with respect to orders
    for delivery placed by Sequenom under this Agreement shall reflect the
    applicable discount set forth in Exhibit 2. 1.  However, the dollar amount
    equal to the Discount Recapture, if any, will be calculated by PerSeptive,
    and notice thereof provided to Sequenom, within forty five (45) days after
    the end of each Agreement Year, with any such amount being carried forward
    from year to year during the term of this Agreement.  At the end of the
    second Agreement Year, PerSeptive will invoice Sequenom for any Discount
    Recapture due, and Sequenom agrees to pay such invoice within thirty (30)
    days of its issuance.  If by the end of the second Agreement Year Sequenom
    has ordered and released for delivery less than *** System Products,
    PerSeptive may in its sole discretion discontinue or modify the discounts
    set forth in Exhibit 2.1 on all future orders placed by Sequenom during the
    term of this Agreement.

    3.5  Notwithstanding any provision to the contrary as may be contained
    herein, if at the end of the third Agreement Year Sequenom shall not have
    ordered and released for delivery   ***  System Products, it shall be
    obligated to purchase from PerSeptive within the next ninety (90) days that
    number of System Products equal to the difference between the number of
    System Products actually ordered by Sequenom and   *** at a fully discounted
    price equal to the discounted price set forth in Exhibit 2.1

4.  ORDERS
    ------

    4.1  Orders for the purchase of Products hereunder shall be submitted to
    PerSeptive on a Purchase Order and shall specifically reference this
    Agreement.  All orders are subject to acceptance by PerSeptive, which shall
    not be unreasonably withheld.  All terms and conditions of sale of Products
    are set forth in this Agreement.  In the event of a conflict between the
    terms and conditions of this Agreement and the terms and conditions on a
    Purchase Order or Invoice, the terms and conditions of this Agreement shall
    prevail except for terms of a Purchase Order specifically designated by
    PerSeptive as terms that supercede the inconsistent terms in this
    Agreement.

    4.2  Upon acceptance of a Purchase Order, PerSeptive shall use commercially
    reasonable efforts to manufacture the Products in accordance with the
    Specifications and to ship such Products in accordance with the delivery
    requirements and Delivery Dates set forth in Section 6.

    4.3  Purchase Orders will include the quantities and types of Products to
    be purchased by Sequenom during the coming year together with an estimated
    schedule of when such Products are to be released for delivery ("release
    date").  Except for Products scheduled to be released within a rolling
    three (3) month period from any calendar date (the "cutoff period"),
    Sequenom may adjust the quantity, type and release date of the Products
    listed on the Purchase Order at its discretion.  The quantity and type of
    Products scheduled to be released within the cutoff period can not be
    altered.

    4.4  PerSeptive's supply obligation hereunder will not extend to more that
    ***        *** of Sequenom's Projected Quantity of Products for the year in
    question. If Sequenom's Product requirements for any quarter exceeds *** of
    Sequenom's Projected Quantity of Products, PerSeptive and Sequenom will
    discuss in good faith the additional amount, if any, that PerSeptive is
    willing to supply consistent with its other obligations and Sequenom will
    adjust its order accordingly. Sequenom shall reimburse PerSeptive promptly
    upon request for all reasonable out of pocket costs and expenses, including
    the cost of carrying increased inventory, to the extent caused by any
    deviation in order quantities from the limits imposed by the preceding
    sentence, and PerSeptive will act reasonably to mitigate any such costs and
    expenses.

    4.5  PerSeptive agrees to use its commercially reasonable efforts to
    provide Sequenom with notice ninety (90) days in advance of (i) any changes
    to the Products listed in Exhibit 2.1 that alter the form, fit or function
    of the Product or (ii) the discontinuance of any Product.  PerSeptive
    reserves the right in its sole and absolute discretion to modify the form,
    fit or function of any Product, or to otherwise modify any Product, and to
    discontinue the manufacture of any Product except for Products which have
    been discontinued PerSeptive shall remain obligated to fill orders as have
    been placed by Sequenom that are subject to accepted Purchase Orders.
    Sequenom reserves the right to terminate this contract with no penalty with
    sixty (60) day written notice should the

                                       5
<PAGE>

    Products change significantly thereby rendering the Products incompatible
    with Sequenom's products or should the change adversely effect Sequenom's
    ability to sell its products. Notwithstanding any such termination, Sequenom
    shall remain obligated to purchase all Products subject to Purchase Orders
    issued by Sequenom.

    4.6  Sequenom hereby grants to PerSeptive and PerSeptive reserves a
    purchase money security interest in each Product purchased hereunder, and
    in any proceeds thereof, for all amounts owing to PerSeptive for or related
    to the product.  Upon request by PerSeptive, Sequenom shall sign any
    document required for PerSeptive to perfect such security interest.
    Payment in full of the purchase price of any Product purchased hereunder
    shall release the security interest on that Product.

    4.7  PerSeptive shall ship in accordance with PerSeptive's standard
    practices.  Sequenom may specify different shipping instructions, subject
    to agreement by PerSeptive, provided that Sequenom will be subject to an
    additional charge if the alternate method increases the cost of shipping
    equal to the increased cost.

    4.8  Unless otherwise agreed to in writing by PerSeptive, all Products
    shall be packed, if appropriate, for shipment and storage in accordance
    with PerSeptive's standard practices.  All packing shall conform to
    requirements of carrier's tariffs.

    4.9  All Products are subject to PerSeptive's standard tolerances for
    specifications.  PerSeptive reserves the right to make substitutions and
    modifications in the Specification of any Product, provided that such
    substitutions or modifications do not materially affect the performance of
    the Products.

    4.10  All patents, copyrights, trade secrets and other intellectual
    property rights (collectively, "Intellectual Property Rights") in or
    related to the Products sold hereunder are and will remain the exclusive
    property of PerSeptive or its licensors.  Sequenom shall not hereby acquire
    any Intellectual Property Rights in the Products except as expressly set
    forth in this Agreement.

    4.11  PerSeptive does not warrant the validity or enforceability of any
    Intellectual Property Rights relating to any Products.  PerSeptive warrants
    and represents, however, that at the time of the sale it is not aware of
    any infringement of any patents or patent applications or other
    Intellectual Property Rights owned by third parties which would prevent
    Sequenom from using or selling the Products.

    4.12  PerSeptive shall have the sole and exclusive right to evaluate any
    suit, claim or proceeding brought against Sequenom alleging that a Product
    purchased by Sequenom from PerSeptive and sold hereunder infringes any
    Intellectual Property Rights of others and to take any and all legal action
    PerSeptive shall deem appropriate with respect thereto.  PerSeptive will
    pay any cost of damages finally awarded against Sequenom in any such
    action.  Sequenom shall have the right to participate and be represented in
    any such suit by its own counsel at its own expense, but Sequenom shall not
    agree to, and PerSeptive shall have no liability for, any settlement,
    compromise or dismissal of such

                                       6
<PAGE>

    suit, or costs incurred in connection therewith, without PerSeptive's
    consent. Should the use of any Products by Sequenom be enjoined, or if
    PerSeptive believes that the use of the Products may infringe the
    Intellectual Property Rights of others, PerSeptive may, at its option,
    require Sequenom to discontinue the use of the allegedly infringing Product
    and shall either (i) substitute an equivalent non-infringing Product, (ii)
    modify the Product so that it no longer infringes but remains equivalent,
    (iii) obtain for Sequenom, at PerSeptive's own expense, the right to
    continue use of such Product, or (iv) refund the purchase price for such
    Product. At PerSeptive's request, Sequenom shall promptly return the Product
    to PerSeptive, at PerSeptive's expense. The foregoing states the entire
    liability of PerSeptive for Intellectual Property Right infringement.

5.  BACKORDERS
    ----------

    5.1  Backorders are defined as orders for System Products (excluding any
    piece, spare or similar component parts) that have not been fully received
    at the designated delivery point within the guaranteed order lead-time,
    subject to Section 6.1 below.

    5.2  Backorders must show an approximate shipping date and indicate the
    reason for such backorder.

    5.3  PerSeptive is required to provide any backorders without any extra
    service or delivery charges.

    5.4  It is the responsibility of PerSeptive to manage backorders and
    provide Sequenom, at no additional cost, with the required Products
    designated in a Purchase Order and to ensure their timely delivery.

         (i)  In case of default, and after notifying PerSeptive, Sequenom may
    obtain the equivalent Products from other suppliers.

         (ii) PerSeptive will be responsible, for the cost difference between
    the Products and the Products from other suppliers.

    5.5  PerSeptive will be in default if the Products are backordered for more
    than ten (10) working days, or if Sequenom feels that the approximate
    shipping date provided by PerSeptive for the backordered Product(s)
    jeopardizes Sequenom's commercial operations and the operation of its
    Customers.

6.  DELIVERY
    --------

    6.1  PerSeptive shall use commercially reasonable efforts to deliver
    Products to Sequenom on or within five (5) business days after the Delivery
    Dates set forth in Purchase Orders accepted by PerSeptive.  Unless
    PerSeptive otherwise agrees, all Delivery Dates shall be ninety (90) days
    or more from the date the Purchase Order is delivered to PerSeptive.

    6.2  In the event circumstances of force majeure as defined in Section 19.1
    exist which would prevent or delay delivery of Products by PerSeptive,
    PerSeptive shall have the right to apportion Products available for
    delivery among its various customers.

7.  SHIPMENT AND RISK OF LOSS
    -------------------------

    7.1  All Products delivered pursuant to the terms of this Agreement shall
    be F.O.B. PerSeptive manufacturing Plant, freight and insurance prepaid and
    added to the invoice, to Sequenom's address or other place of delivery as
    designated time to time by Sequenom, provided, however, that if delivery is
    requested to a site other than Sequenom's address set forth in Section 18,
    Sequenom shall be responsible to qualify delivery to such other site by
    specifying in sufficient detail to PerSeptive all of the necessary shipping
    and installation requirements for such site.  Sequenom shall indemnify and
    hold PerSeptive harmless, including the reimbursement of all reasonable
    expenses incurred by PerSeptive, as a result of Sequenom's failure to
    properly qualify delivery.  Sequenom shall use its best efforts to assist
    PerSeptive in arranging any desired insurance (in amounts that Sequenom
    shall determine) and transportation, via airfreight unless otherwise
    specified in writing, to any destinations specified in writing from time to
    time.  All customs, duties, costs, taxes, insurance premiums, and other
    expenses relating to such transportation and delivery shall be at
    Sequenom's expense.

    7.2  Title, with the exception of certain technology that is licensed to
    Sequenom as provided in this Agreement, and risk of loss with respect to
    all Products shall pass from PerSeptive to Sequenom upon transfer to the
    carrier.

8.  INSTALLATION AND ACCEPTANCE
    ---------------------------

    8.1  Installation of Products by PerSeptive may be purchased by Sequenom at
    the time of issuance of a Purchase Order by including a statement that
    installation by PerSeptive of the designated Product is requested, or at
    any other time.  If a Purchase Order with installation by PerSeptive
    included is accepted by PerSeptive, PerSeptive shall install the Product,
    in accordance with PerSeptive's then standard installation practice, at the
    Customer location or Sequenom's location, as designated on the Purchase
    Order or as otherwise agreed.  The cost of installation for the Product in
    question will be included on the Purchase Order and may be invoiced by
    PerSeptive with the invoice for the Product, or when installation by
    PerSeptive is otherwise agreed to, may be separately invoiced by
    PerSeptive, at PerSeptive's discretion.  PerSeptive will use commercially
    reasonable efforts to schedule and complete installation in a timely
    fashion.  PerSeptive and Sequenom will cooperate with each other to
    coordinate each other's installation efforts.

    8.2  For Products installed by PerSeptive, PerSeptive shall have no
    obligation to integrate the Product with any product of Sequenom, who shall
    be solely responsible for system integration.

    8.3  For Products installed by PerSeptive, installation shall be complete,
    and acceptance by Sequenom shall occur, when the Product passes
    PerSeptive's standard

                                       8
<PAGE>

    installation and test procedures in effect at the time of installation. For
    Products that are not installed by PerSeptive, acceptance by Sequenom occurs
    upon shipment and will be deemed to have occurred unless Sequenom
    demonstrates within thirty (30) days after delivery that the Product does
    not pass PerSeptive's standard installation and test procedures or satisfy
    the applicable Specifications, in which case acceptance occurs when such
    procedures are passed. Sequenom shall notify PerSeptive in writing of its
    rejection of the Product, specifying in sufficient detail the nature of the
    problem, and shall await PerSeptive's instructions with regard to
    disposition of the rejected Product which shall come no less than forty
    eight (48) hours after receiving the notification. PerSeptive shall use its
    reasonable best efforts to either repair on-site or off site, or, at its
    option, to replace the rejected Product with conforming Product. In any
    event, a Product that passes PerSeptive's standard installation and test
    procedures shall be at the Customer's facility as soon as commercially
    feasible. PerSeptive will use its reasonable commercial efforts to provide a
    Product that passes such tests no later than ten (10) working days after the
    initial Product failed the installation and test procedures. If instructed
    by PerSeptive, and upon receipt by Sequenom of a return authorization from
    PerSeptive, Sequenom shall ship back to PerSeptive any defective Product or
    any component thereof at Sequenom's cost. PerSeptive shall ship any
    replacement product back to Sequenom or the Customer at PerSeptive's cost.
    Refund including any freight and insurance costs incurred for authorized
    returned Products, repair or replacement shall be Sequenom's remedy for any
    rejection of any Product. Products may not be returned to PerSeptive under
    any circumstances without PerSeptive's prior written authorization. Any
    Product not repairable on-site and returned hereunder to PerSeptive may be
    conformed to comply with the Specifications at PerSeptive's facilities and
    thereafter used to fill a future Sequenom order.

9.  TRAINING
    --------

    9.1  PerSeptive commits to train, tuition free, two (2) designated Sequenom
    employees in the installation and routine maintenance of the Products.  The
    training will be conducted concurrently in a single class of two (2) weeks
    duration at PerSeptive's facility as part of PerSeptive's standard training
    programs and will be scheduled and executed within one hundred twenty (120)
    days of the Effective Date.  Sequenom may request from time to time due to
    employee changes or increased customer demand, and PerSeptive shall grant,
    additional training of the type set forth above.  The training will be
    scheduled on a mutually agreed upon basis and shall be invoiced to Sequenom
    at a rate of                        ***

10. PAYMENT
    -------

    10.1  Upon or after delivery of the Product to the F.O.B. point, PerSeptive
    shall submit an Invoice therefor.  Sequenom agrees to pay the amount of
    Invoices submitted by PerSeptive within thirty (30) days from date of
    Invoice.

*** Portions of this page have been omitted pursuant to a request for
Confidential Treatment and filed separately with the Commission.

                                       9
<PAGE>

    10.2  If payment is not received by the due date, a service charge may be
    added at the rate of 1.5 % per month (18% per year) or the maximum legal
    rate, whichever is less, to unpaid invoices from the due date thereof.
    Sequenom agrees to pay such service charges and agrees to reimburse
    PerSeptive reasonable attorney's fees and other out of pocket expenses of
    collection if PerSeptive engages counsel and/or incurs expenses to collect
    overdue amounts.

    10.3  In the event that Sequenom shall fail to pay any past due Invoice
    within ten (10) days of receipt of notice from PerSeptive, PerSeptive may,
    at any time and in its sole discretion, limit or cancel the credit of
    Sequenom as to time and amount, and as a consequence, may demand full
    payment or partial payment before delivery of any unfilled Purchase Order
    of this Agreement, and may demand assurance of Sequenom's due performance.
    Upon making such demand, PerSeptive may suspend production, shipment,
    and/or deliveries.  If, within the period stated in such demand, but in no
    event longer than thirty (30) days, Sequenom fails to agree and comply with
    such different terms of payment, and/or fails to give adequate assurance of
    due performance, PerSeptive may (i) by notice to Sequenom, treat such
    failure or refusal as a repudiation by Sequenom of the accepted Purchase
    Orders not then fully performed, whereupon PerSeptive may cancel all
    further deliveries and any amounts unpaid hereunder shall immediately
    become due and payable; or (ii) make shipments under reservation of a

11. RESALE RESTRICTIONS
    -------------------

    11.1  PerSeptive hereby grants a right to Sequenom to resell the Products,
    bundled with the Sequenom system as described in Section 11.2, only to
    locations      ***
     ***
     ***
     ***
     ***      . If a location other than those listed above is designated as the
    place of installation on a Purchase Order accepted by PerSeptive, the
    parties shall be deemed to have agreed on such other location.

    11.2  It is the intention of the parties that this Agreement represents a
    value added resale business relationship.  Accordingly, Sequenom's resale
    of Products shall be in conjunction with other Sequenom products,
    ***
     ***.  Sequenom shall have no right to resell any Product purchased
    hereunder as a stand-alone Mass Spec Product, and any attempt to do so
    shall be deemed a material breach of this Agreement by Sequenom for which
    there is no right of cure, notwithstanding anything contained in this
    Agreement to the contrary.

    11.3  As set forth in Section 15.1, the price of Products payable by
    Sequenom pursuant to this Agreement is Confidential Information of
    PerSeptive, and Sequenom shall not furnish such price in any quote of any
    Sequenom system that includes a Product, or quote other items separately so
    that such price can be deduced, or otherwise disclose such price to any
    third party.

12. WARRANTY
    --------

    12.1  PerSeptive warrants that the Products will conform to the
    Specifications at the time of delivery and will be free from defects in
    materials and workmanship for a period of six (6) months.  The warranty
    period begins on the date of installation if the Products are installed by
    PerSeptive, but in no event later than thirty (30) days after shipment, or
    otherwise on the date of delivery.  The foregoing warranties do not include
    periodic maintenance or calibration recommended for some Products, unless
    specifically covered in the express written warranty terms, if any,
    accompanying the delivery of such Products.  To the extent then generally
    available to PerSeptive customers, Sequenom may purchase extended support
    coverage or a service contract on Products purchased pursuant to this
    Agreement at PerSeptive's then applicable retail rate, less    ***   .


    12.2  If PerSeptive receives notice of defects or nonconformance to the
    Specifications during the warranty period, PerSeptive will, at its option,
    repair (and recalibrate only as necessitated by repairs) or replace the
    affected Products. If PerSeptive is unable, within the times designated in
    Section 12.6, to repair, replace or correct a defect or non-conformance in a
    Product to a condition as warranted, Sequenom will be entitled to a refund
    of the purchase price upon prompt return of the Product to PerSeptive.
    PerSeptive will pay expenses for shipment of both defective and repaired or
    replacement Products.

    12.3  The above warranties do not apply to defects resulting from improper
    or inadequate maintenance or calibration by Sequenom or its Customers;
    Sequenom or third party supplied hardware or software, interfacing or
    supplies; unauthorized modification; improper use or operation outside of
    the Specifications for the Product; abuse, negligence, accident, loss or
    damage in transit; improper site preparation; or unauthorized maintenance
    or repair.

    12.4  Sequenom's sole remedies under PerSeptive's warranty shall be limited
    to repair or replacement of the Product that failed to conform to such
    warranty, or refund of the purchase price of the Product.  Repair,
    replacement or refund shall be at the sole discretion of PerSeptive.

    12.5  THE FOREGOING WARRANTIES ARE EXCLUSIVE AND NO OTHER WARRANTY, EXPRESS
    OR IMPLIED, IS GIVEN BY PERSEPTIVE, INCLUDING THOSE OF MERCHANTABILITY OR
    FITNESS FOR A PARTICULAR PURPOSE, ALL OF WHICH ARE EXPRESSLY DISCLAIMED.

<PAGE>

    12.6  All Product defects or suspected defects during the warranty period
    will be managed by an authorized Sequenom representative (who has undergone
    training as provided in Section 9) who shall place a call to PerSeptive's
    designated service center followed up with the description of the Product
    problem in sufficient detail as to allow PerSeptive to assess the source of
    the problem.  All service calls placed by Sequenom will be responded to
    either by fax or by phone within two (2) business days with a proposed
    remedy to the Customer's problem being determined by PerSeptive as soon as
    commercially feasible after Sequenom's initial service call.  PerSeptive
    will use its reasonable commercial efforts to see to it that the Customer's
    Product is either fully operational or that a replacement instrument is
    delivered to the Customer if it is determined that an on-site repair is not
    possible with the allotted time within ten (10) business days of the
    initial service call.  Any Product not repairable on-site and returned
    hereunder to PerSeptive may be conformed to comply with the Specifications
    at PerSeptive's facilities and thereafter used to fill a future Sequenom
    order.

13. LICENSE RIGHTS

    14.1  PerSeptive hereby grants Sequenom a non-transferable,
    nonsublicensable, nonexclusive license to use the Trademarks, without
    modification unless approved by PerSeptive as set forth in Section 14.2,

    displayed in a size no greater than of those of PerSeptive and (ii)
    Sequenom's trademarks and identification are placed on the Products in a
    manner that is not likely to cause confusion with PerSeptive's trademarks
    and brand identification.

    14.2  Within thirty (30) days of the Effective Date, Sequenom will submit
    for approval by PerSeptive, which shall not be unreasonably withheld, a
    design layout showing the use of Sequenom's trademarks and brand
    identification on the Products.  Any subsequent changes to such layout will
    similarly require PerSeptive's approval.

    14.3  All advertisements and other promotional materials and other
    descriptions of systems that include Products published by Sequenom shall
    include a notation that the Products have been manufactured by PerSeptive
    under agreement with Sequenom and an indication of the applicable license
    rights accompanying the sale of Products as set forth in Sections 13.1 and
    13.2.

15. CONFIDENTIALITY

    15.1  During the term of this Agreement, all Confidential Information
    exchanged or developed under this Agreement shall be kept strictly
    confidential by either party and shall not be used by either party nor
    disclosed by either party to any third party for any purpose except those

    this Agreement.  By way of example but not by way of limitation, all
    information relating to PerSeptive's sale of Products (e.g., price,
    quantity, discount, delivery schedule, Product improvements, SOP documents,
    operation

                                       13

    and Specifications shall be deemed PerSeptive's Confidential Information.

    15.2  The provisions of Section 15.1 shall survive any termination of this
    Agreement and continue in force for a period of five (5) years following
    the effective date of any such termination.

16. LIMITATION OF LIABILITY; INDEMNIFICATION
    ----------------------------------------

    16.1  Except solely with respect to damages for personal injury caused by
    PerSeptive's negligence or willful misconduct, PerSeptive's liability
    arising out of this Agreement, including without limitation on account of
    any breaches or default, or from or on account of any Products sold
    pursuant to this Agreement, or the use thereof, arising from whatever
    cause, whether tort, breach of contract, warranty, or otherwise, excepting
    solely fraud, is limited to one million dollars ($1,000,000) in the
    aggregate.  This Section does not limit liability for bodily injury of a
    person.

    16.2  NOTWITHSTANDING ANYTHING CONTAINED IN THIS AGREEMENT TO THE CONTRARY,
    IN NO EVENT SHALL PERSEPTIVE BE LIABLE, WHETHER IN CONTRACT, TORT,
    WARRANTY, OR UNDER ANY STATUTE (INCLUDING WITHOUT LIMITATION ANY TRADE
    PRACTICE, UNFAIR COMPETITION OR OTHER STATUTE OF SIMILAR IMPORT) OR ON ANY
    OTHER BASIS, FOR INDIRECT, PUNITIVE, MULTIPLE, INCIDENTIAL, CONSEQUENTIAL
    OR SPECIAL DAMAGES SUSTAINED BY SEQUENOM OR ANY OTHER PERSON ARISING OUT OF
    OR IN CONNECTION WITH ANY ASPECT OF THIS AGREEMENT OR ITS PERFORMANCE OR
    ANY FAILURE IN PERFORMANCE OR BREACH, OR THE USE OR PERFORMANCE, OR
    CONSEQUENCES OF USE OR PERFORMANCE, OF ANY PRODUCTS MANUFACTURED OR
    FURNISHED BY PERSEPTIVE WHETHER OR NOT FORESEEABLE AND WHETHER OR NOT
    PERSEPTIVE IS ADVISED OF THE POSSIBILITY OF SUCH DAMAGE, INCLUDING, WITHOUT
    LIMITATION, DAMAGES ARISING FROM OR RELATED TO LOSS OF USE, LOSS OF DATA,
    FAILURE OR INTERRUPTION IN THE OPERATION OF ANY EQUIPMENT OR SOFTWARE,
    DELAY IN REPAIR OR REPLACEMENT, OR FOR LOSS OF REVENUE OR PROFITS, LOSS OF
    GOODWILL, OR LOSS OF BUSINESS UNLESS EXPLICITLY PROVIDED FOR HEREIN.

    16.3  Sequenom agree to defend PerSeptive and its Affiliates at its cost
    and expense, and will indemnify and hold PerSeptive, its Affiliates and
    their respective directors, officers, employees and agents (the "PerSeptive
    Indemnified Parties") harmless from and against any liabilities, losses,
    costs, damages, fees or expenses (including reasonable attorney's fees)
    arising out of any claim relating to (i) any breach by Sequenom of any of
    its representations, warranties or obligations pursuant to this Agreement
    or (ii) personal injury or property damage from the use, sale or other
    disposition of any Product or service offered by Sequenom and/or its
    respective licensees or collaborators or (iii)

                                       14
<PAGE>

    the negligence or willful misconduct of Sequenom, except in all cases to the
    extent caused by the negligence or Willful misconduct of PerSeptive.

    16.4  PerSeptive agrees to defend Sequenom and its Affiliates at its cost
    and expense, and will indemnify and hold Sequenom, its Affiliates and their
    respective directors, officers, employees and agents (the "Sequenom
    Indemnified Parties") harmless from and against any liabilities, losses,
    costs, damages, fees or expenses (including reasonable attorney's fees)
    arising out of any claim relating to (i) any breach by PerSeptive of any of
    its representations, warranties or obligations pursuant to this Agreement
    or (ii) personal injury or property damage from the negligent development
    and manufacture of any Product or service offered by PerSeptive or its
    licensees or collaborators or (iii) the negligence or willful misconduct of
    PerSeptive, except in all cases to the extent caused by the negligence or
    willful misconduct of Sequenom.

    16.5  Whenever any claim shall arise for indemnification hereunder, the
    party seeking indemnification (the "Indemnified Party") shall promptly
    notify the party from whom indemnification is sought (the "Indemnifying
    Party").  Such notice shall specify the nature of the claim and, when
    known, the facts constituting the basis for, as well as the amount or an
    estimate of the amount of the liability arising from, such claim.  Failure
    to promptly notify shall not relieve a Party from its indemnity obligations
    hereunder except to the extent of prejudice caused by such failure.  The
    Indemnified Party shall not settle or compromise any claim by a third party
    for which it is entitled to indemnification hereunder without the prior
    written consent of the Indemnifying Party, which shall not be unreasonably
    withheld, unless suit shall have been instituted against it and the
    Indemnifying Party shall not have taken control of such suit after
    notification thereof as provided in Section 16.6.

    16.6  In connection with any claim giving rise to indemnity under Section
    16 of this Agreement, the Indemnifying Party at its sole cost and expense
    may, upon written notice to the Indemnified Party, assume the defense of
    any such claim or legal proceeding if it acknowledges to the Indemnified
    Party in writing its obligations to indemnify the Indemnified Party with
    respect to all elements of such claim.  The Indemnified Party shall be
    entitled to participate in (but not control) the defense of any such
    action, with its counsel and at its own expense.  If the Indemnifying Party
    does not assume the defense of any such claim or litigation resulting
    therefrom within thirty (30) days after the date notice of such claim is
    given, the Indemnified Party may defend against such claim or litigation,
    without prejudice to pursue its rights of indemnity.  In such event, the
    Indemnified Party may defend in a manner as it may deem appropriate,
    including, but not limited to, settling such claim or litigation, but only
    after giving written notice of the same to the Indemnifying Party, on such
    terms as the Indemnified Party may deem appropriate, and the Indemnifying
    Party shall be entitled to participate in (but not control) the defense of
    such action, with its counsel and at its own expense.  The Parties shall
    cooperate with each other in the defense of any such third party claim
    pursuant to this Section 16.

    17.1  The term of this Agreement shall be for the period beginning on the
    Effective Date and ending three (3) years thereafter.

    17.2  This Agreement shall terminate upon written notice by one Party to
    the other in the event the other Party shall become insolvent, or shall ask
    its creditors for a moratorium, or shall file a voluntary bankruptcy

    Party to perform any of its obligations under this Agreement by notifying
    the other Party in writing of such default and allowing the other party

    the failure to pay money, in which case the defaulting party shall have
    only five days to cure such default after receiving written notice of
    nonpayment.  If such default is not cured within thirty (30) days from
    receipt of such notice of default (or five (5) days in the case of non-
    payment of money owed), the non-defaulting party may terminate this
    Agreement by written notice to the defaulting party.

    following provisions shall survive the termination of this Agreement: this
    Section 17.4, Section 15, Section 16, Section 18, and Section 19.  Any
    rights of Seller to payments accrued through termination as well as
    obligation of the parties under firm orders for purchase and delivery of
    Products at the time of such termination shall remain in effect, except
    that in the case of termination under Section 17.3, the terminating party
    may elect whether obligations under firm orders will remain in effect and
    except that PerSeptive will have no obligation to manufacture and deliver
    Products that have Delivery Dates more than six (6) months after the date
    of termination.

    continue in full force and effect.

OBJECTIVE:

The objective of this cooperative research project is to develop and implement a
high speed mass spectrophotometer based genotyping system for livestock. This
requires a system to utilize primers for single nucleotide polymorphism (SNP) in
livestock.

APPROACH:

A mass spectrophotometer based high speed genotyping system is required for use
of SNP's to genotype livestock populations. To efficiently use expressed
sequence tags (EST) sequence data in livestock and link this information with
the human genome database, we must be able to genotype SNP's in livestock
populations. Preliminary studies with the Sequenom DNA MassArray analytical
system have demonstrated this system can be used effectively to genotype SNP's
in livestock. This system will be implemented and upgraded to develop markers
for SNP's and map these markers on the ARS linkage maps.

STATEMENT OF MUTUAL INTEREST:

Both parties are actively engaged in independent research projects to identify
and implement efficient SNP genotyping systems. This project combines Sequenom's
expertise and technology relating to their DNA MassArray Basic System Plus and
ARS's expertise and technology relating to SNP marker development to develop and
implement a high speed SNP genotyping system. The parties agree that meeting the
objectives of this project will strengthen and enhance ongoing research within
the scope of this agreement.

THE COOPERATOR AGREES TO:

1.   Work closely with ARS in planning and providing engineering and systems
support for conducting the research outlined below.

2.   Conduct at ARS facilities and elsewhere as appropriate, engineering and
systems support research to upgrade the DNA MassArray Analytical System for use
in developing markers for SNP's..... activities include:

a.   Provide for the use during this project of a DNA MassArray Basic System
Plus incorporating the following components: a High-speed Bruker/SEQUENOM Array
Mass Spectrometer; a Spectrojet Nanoliter Dispenser; a SEQUENOM BioMASS
lnformatics Workstation and use of appropriate software; Beckman Multimek
Instrument with SEQUENOM Magnetic Lifters. Provide hardware and software
upgrades to the system as they become available.

b.   Provide SEQUENOM 96 D SpectroChipTM , reagents, and the magnetic beads
required in sample preparation for 200,000 elements (excluding the reagents
provided for by ARS and

outlined below). An element is defined as a sample pad on SEQUENOM's
SpectroChipTM (Patent US 5,605,798).

c.   Assist in developing markers to run on this "system."

d.   Assist in integrating DNA MassArray data with the ARS livestock database.

ARS AGREES TO:

1.   Work closely with the cooperator in planning and conducting the research
outlined above.

2.   Conduct research on the following aspects of the project:

a.   Develop primers to amplify specific regions of DNA (Primers and PCR
reagents will be provided by ARS).

b.   Identify SNP markers within the amplified fragments.

c.   Synthesize probe primers that can be used with the DNA MassArray Basic
System to genotype the SNPs (reagents to be provided by ARS include primers,
neucleotides, enzymes, biotinylated primers).

d.   Utilize SNP genotypic data to place the markers on the linkage map.

MUTUAL AGREEMENTS:

1.   The estimated budget, Form ARS-454, is hereby incorporated into the
agreement. The awarding agency will reimburse the Cooperator for costs related
to salaries, material, supplies in the amount of $436,000, and will contribute
in-house resources in the amount of $574,900. As evidence of the Cooperator's
contribution to this project the Cooperator will provide in-house resources in
the amount of $312,187.50.

2.   Payments to the Cooperator will be made quarterly via Electronic Funds
Transfer (EFT), upon submission of a properly executed invoice. See ARS-452,
Part 15 (Attached). Reimbursement for the use of the DNA MassArray Basic System
will be made after delivery of the system and evidence that ARS can produce
acceptable results; reimbursement of expenses associated with the BioMass Probe
reaction units ($150,000/100,000 elements) will be based on quantity used; and
the monthly maintenance fee will be reimbursed on a quarterly basis.

3.   The use of the DNA MassArray Basic System Plus and Spectrochip (System)
will be solely used for purposes of livestock SNP analysis. The Cooperator shall

                        Instructions for Certification
                        ------------------------------

1.   By signing and submitting this form, the grantee is providing the
     certification set out on pages 1 and 2

2.   The certification set out on pages 1 and 2 is a material representation of
fact upon which reliance is placed when the agency awards the grant. If it is
later determined that the grantee knowingly rendered a false certification, or
otherwise violates the requirements of the Drug-Free Workplace Act, the agency,
in addition to any other remedies available to the Federal Government, may take
action authorized under the Drug-Free Workplace Act.

3.   Workplaces under grants, for grantees other than individuals, need not be
identified on the certification. If known, they may be identified in the grant
application. If the grantee does not identify the workplaces as the time of
application, or upon award, if there is no application, the grantee must keep
the identity of the workplace(s) on file in its office and make the information
available for Federal inspection. Failure to identify all known workplaces
constitutes a violation of the grantee's drug-free workplace requirements.

4.   Workplace identifications must include the actual address of buildings (or
parts of buildings) or other sites where work under the grant takes place.
Categorical descriptions may be used (e.g., all vehicles of a mass transit
authority or State highway department while in operation, State employees in
each local unemployment office, performers in concert halls or radio studios).

5.   If the workplace identified to the agency changes during the performance of
the grant, the grantee shall inform the agency of the change(s), if it
previously identified the workplaces in question (see paragraph 3).

6.   Definitions of terms in the Nonprocurement Suspension and Debarment common
rule and Drug-Free Workplace common rule apply to this certification. Grantees'
attention is called, in particular, to the following definitions from these
rules:

"Controlled" substance means a controlled substance in Schedules I through V of
the Controlled Substances Act (21 U.S.C. 812) and as further defined by
regulation (21 CFR 1308.11 through 1308.15);

"Conviction" means a finding of guilt (including a plea of nolo contendere) or
imposition of sentence, or both, by any judicial body charged with the
responsibility to determine violations of the Federal or State criminal drug
statutes;

"Criminal drug statute" means a Federal or non-Federal criminal drug statute
involving the manufacture, distribution, dispensing, use or possession of any
controlled substance;

"Employee" means the employee of a grantee directly engaged in the performance
of work under a grant including: (i) all "direct charge" employees; (ii) all
"indirect charge" employees unless their impact or involvement is insignificant
to the performance of the grant; and, (iii) temporary personnel and consultants
who are directly engaged in the performance of work under the grant and who are
on the grantee's payroll. This definition does not include workers not on the
payroll of the grantee (e.g., volunteers, even if used to meet a matching
requirement; consultants or independent contractors not on the grantee's
payroll; or employees of subrecipients or subcontractors in covered workplaces).

                              Related to Lobbying

________________________________________________________________________________

Section 319 of Public Law 101-121 (31 U.S.C.), signed into law on October 23,
1989, imposes new prohibitions and requirements for disclosure and certification
related to lobbying on recipients of Federal contracts, grants, cooperative
agreements, and loans. Certain provisions of the law also apply to Federal
commitments for loan guarantees and insurances; however, it provides exemptions
for Indian tribes and tribal organizations.

Effective December 23, 1989, current and prospective recipients (and their
subtier contractors and/or subgrantees) will be prohibited from using Federal
funds, other than profits from a Federal contract, for lobbying Congress or any
Federal agency in connection with the award of a particular contract, grant,
cooperative agreement or loan. In addition, for each award action in excess of
$100,000 (or $150,000 for loans) on or after December 23, 1989, the law requires
recipients and their subtier contractors and/or subgrantees to: (1) certify that
they have neither used nor will use any appropriated funds for payment to
lobbyists, (2) disclose the name, address, payment details, and purpose of any
agreements ,with lobbyists whom recipients or their subtier contractors or
subgrantees will pay with profits or nonappropriated funds on or after December
23, 1989; and (3) file quarterly updates about the use of lobbyists if material
changes occur in their use. The law establishes civil penalties for
noncompliance.

If you are a current recipient of funding or have an application, proposal or
bid pending as of December 23, 1989, the law will have the following immediate
consequences for you:

- -    You are prohibited from using appropriated funds (other than profits from
Federal contracts) on or after December 23, 1989, for lobbying Congress or any
Federal agency in connection with a particular contract, grant, cooperative
agreement, or loan;

- -    you are required to execute the attached certification at the time of
submission of an application or before any action in excess of $100,000 is
awarded; and

- -    you will be required to complete the lobbying disclosure form if the
disclosure requirements apply to you.

Regulations implementing Section 319 of Public Law 101 - 121 have been published
as an Interim Final Rule by the Office of Management and Budget as Part III of
the February 26, 1990 Federal Register (pages 6736-6746).

                                 INSTRUCTIONS

GENERAL

This form is for use in submitting INTERIM and FINAL invention reports to the
Contracting Officer and for use in the prompt notification of the award of
subcontracts containing a "Patent Rights" clause. If the form does not afford
sufficient space, multiple forms may be used or plain sheets of paper with
proper identification of information by Item may be attached.

An INTERIM report is due at least every 12 months from the date of contract
award and shall include (a) a listing of "Subject Inventions" during the
reporting period, (b) a certification of compliance with required invention
identification and disclosure procedures together with a certification of
reporting of all "Subject Inventions." and (c) any required information not
previously reported on subcontracts awarded during the reporting period and
containing a "Patent Rights" clause.

A FINAL report is due within 6 months if contractor is a small business firm of
domestic nonprofit organization and within 3 months for all others after
completion of the contract work and shall include (a) a listing of all "Subject
Inventions" required by the contract to be reported, and (b) any required
information not previously reported on subcontracts awarded during the course of
or under the contract and containing a "Patent Rights" clause.

While the form may be used for simultaneously reporting inventions and
subcontracts, it may also be used for reporting, promptly after award,
subcontracts containing a "Patent Rights" clause.

Dates shall be entered where indicated in certain Items on this form and shall
be entered in four or six digit numbers in the order of year and month (YYMM) or
year, month and day (YYMMDD). Example: April 1981 should be entered as 8104 and
April 15, 1981 should be entered as 810415.

rights in a reported invention may not be determined solely by the terms of the
"Patent Rights" clause in the contract. Example (1): If an invention is made by
a Government employee assigned to work with a contractor, the Government rights
in such an invention will be determined under Executive Order 10096. Example
(2): I f an invention is made under a contract by joint inventors and one of the
inventors is a Government employee, the Government's rights in such an
inventor's interest in the invention will also be determined under Executive
Order 10096, except where the contractor is a small business or nonprofit
organization, in which case the provisions of Section 202(c) of P.L. 96-517 will
apply.

Item 5g, 1.  Self-explanatory.

<PAGE>

     prosecution and maintenance of any applications claiming such exclusively
     licensed inventions and any patents or other IP grants that may issue on
     such applications.  The Collaborator may waive its exclusive license rights
     on any application, patent or other IP grant at any time, and incur no
     subsequent compensation obligation for that application, patent or IP
     grant.

6.4  Prosecution of Intellectual Property Applications.  Within one month of
     -------------------------------------------------
     receipt or filing, each Party shall provide the other Party with copies of
     the applications and all documents received from or filed with the relevant
     patent or other EP office in connection with the prosecution of such
     applications.  Each Party shall also provide the other Party with the power
     to inspect and make copies of all documents retained in the patent or other
     IP application files by the applicable patent or other IP office.  Where
     licensing is contemplated by Collaborator, the Parties agree to consult
     with each other with respect to the prosecution of applications for PHS
     Subject Inventions described in Article 6.3 and joint Subject Inventions
     described in Article 6.4. If the Collaborator elects to file and prosecute
     IP applications on joint Subject Inventions pursuant to Article 6.4, PHS
     will be granted an associate power of attorney (or its equivalent) on such
     IP applications.

Article 7. Licensing

7.1  Option for Commercialization License.  With respect to Government IP rights
     to any Subject Invention not made solely by the Collaborator's employees
     for which a patent or other IP application is filed, PHS hereby grants to
     the Collaborator an exclusive option to elect an exclusive or nonexclusive
     commercialization license, which is substantially in the form of the
     appropriate model PHS license agreement.  This option does not apply to
     Subject Inventions conceived prior to the effective date of this CRADA that
     are reduced to practice under this CRADA, if prior to that reduction to
     practice, PHS has filed a patent application on the invention and has
     licensed it or offered to license it to a third party.  The terms of the
     license will fairly reflect the nature of the invention, the relative
     contributions of the Parties to the invention and the CRADA, the risks
     incurred by the Collaborator and the costs of subsequent research and
     development needed to bring the invention to the marketplace.  The field of
     use of the license will be commensurate with the scope of the RP.

7.2  Exercise of License Option.  The option of Article 7.1 must be exercised by
     written notice mailed within three (3) months after either (i) Collaborator
     receives written notice from PHS that the patent or other IP application
     has been filed; or (ii) the date Collaborator files such IP application.
     Exercise of this option by the Collaborator initiates a negotiation period
     that expires nine (9) months after the exercise of the option.  If the last
     proposal by the Collaborator has not been responded to in writing by PHS
     within this nine (9) month period, the negotiation period shall be extended
     to expire one (1) month after PHS so responds, during which month the
     Collaborator may accept in writing the final license proposal of PHS.  In
     the absence of such acceptance, or an extension of the time limits by PHS,
     PHS will be free to license such IP rights to others.

                                 Page 5 of 13
<PAGE>

     In the event that the Collaborator elects the option for an exclusive
     license, but no such license is executed during the negotiation period, PHS
     agrees not to make an offer for an exclusive license on more favorable
     terms to a third party for a period of six (6) months without first
     offering Collaborator those more favorable terms. These times may be
     extended at the sole discretion of PHS upon good cause shown in writing by
     the Collaborator.

7.3  License for PHS Employee Inventions and Joint Inventions.  Pursuant to 15
     U.S.C. (S) 37 10a(b)(1)(A), for Subject Inventions made under this CRADA by
     a PHS employee(s) or jointly by such employee(s) and employees of the
     Collaborator pursuant to Articles 6.3 and 6.4 and licensed pursuant to the
     option of Article 7.1, the Collaborator grants to the Government a
     nonexclusive, nontransferable, irrevocable, paid-up license to practice the
     invention or have the invention practiced throughout the world by or on
     behalf of the Government.  In the exercise of such license, the Government
     shall not publicly disclose trade secrets or commercial or financial
     information that is privileged or confidential within the meaning of 5
     U.S.C. 552(b)(4) or which would be considered as such if it had been
     obtained from a non-Federal party.

7.4  License in Collaborator Inventions.  Pursuant to 15 U.S.C. (S) 3710a(b)(2),
     for inventions made solely by Collaborator employees under this CRADA
     pursuant to Article 6.2, the Collaborator grants to the Government a
     nonexclusive, nontransferable, irrevocable, paid-up license to practice the
     invention or have the invention practiced throughout the world by or on
     behalf of the Government for research or other Government purposes.

7.5  Third Party License.  Pursuant to 15 U.S.C. (S) 3710a(b)(1)(B), if PHS
     grants an exclusive license to a Subject Invention made wholly by PHS
     employees or jointly with a Collaborator under this CRADA, pursuant to
     Articles 6.3 and 6.4, the Government shall retain the right to require the
     Collaborator to grant to a responsible applicant a nonexclusive, partially
     exclusive, or exclusive sublicense to use the invention in Collaborator's
     licensed field of use on terms that are reasonable under the circumstances;
     or if the Collaborator fails to grant such a license, to grant the license
     itself.  The exercise of such rights by the Government shall only be in
     exceptional circumstances and only if the Government determines (i) the
     action is necessary to meet health or safety needs that are not reasonably
     satisfied by Collaborator, (ii) the action is necessary to meet
     requirements for public use specified by Federal regulations, and such
     requirements are not reasonably satisfied by the Collaborator; or (iii) the
     Collaborator has failed to comply with an agreement containing provisions
     described in 15 U.S.C. 3710a(c)(4)(B).  The determination made by the
     Government under this Article is subject to administrative appeal and
     judicial review under 35 U.S.C. 203(2).

7.6  Joint Inventions Not Exclusively Licensed.  In the event that the
     Collaborator does not acquire an exclusive commercialization license to EP
     rights in all fields in joint Subject Inventions described in Article 6.4,
     then each Party shall have the right to use the joint

                                NHGRI-Sequenom
                            PHS CRADA Model 3/15/99

<PAGE>

     Subject Invention and to license its use to others in all fields not
     exclusively licensed to Collaborator. The Parties may agree to a joint
     licensing approach for such EP rights.

Article 8. Proprietary Rights and Publication

8.1  Right of Access.  PHS and the Collaborator agree to exchange all Subject
     Data produced in the course of research under this CRADA.  Research
     Materials will be shared equally by the Parties to the CRADA unless other
     disposition is agreed to by the Parties.

All Parties to this CRADA will be free to utilize Subject Data and Research
Materials for their own purposes, consistent with their obligations under this
CRADA.

8.2  Ownership of Subject Data and Research Materials.  Subject to the sharing
     requirements of Paragraph 8.1 and the regulatory filing requirements of
     Paragraph 8.3, the producing Party will retain ownership of and title to
     all Subject Inventions, all Subject Data and all Research Materials
     produced solely by their investigators.  Jointly developed Subject
     Inventions, Subject Data and Research Materials will be jointly owned.

8.3  Dissemination of Subject Data and Research Materials.  To the extent
     permitted by law, the Collaborator and PHS agree to use reasonable efforts
     to keep Subject Data and Research Materials confidential until published or
     until corresponding patent applications are filed.  Any information that
     would identify human subjects of research or patients will always be
     maintained confidentially.  To the extent permitted by law, the
     Collaborator shall have the exclusive right to use any and all CRADA
     Subject Data in and for any regulatory filing by or on behalf of
     Collaborator, except that PHS shall have the exclusive right to use Subject
     Data for that purpose, and authorize others to do so, if the CRADA is
     terminated or if Collaborator abandons its commercialization efforts.
     Collaborator acknowledges the basic research mission of the PHS, and agrees
     that after publication, PHS may make unpatented research materials arising
     out of this CRADA available to third parties for further research.

8.4  Proprietary/Confidential Information.  Each Party agrees to limit its
     disclosure of Proprietary/Confidential Information to the amount necessary
     to carry out the Research Plan of this CRADA, and shall place a
     confidentiality notice on all such information.  Confidential oral
     communications shall be reduced to writing within 30 days by the disclosing
     Party. Each Party receiving Proprietary/Confidential Information agrees
     that any information so designated shall be used by it only for the
     purposes described in the attached Research Plan. Any Party may object to
     the designation of information as Proprietary/Confidential Information by
     another Party. Subject Data and Research Materials developed solely by the
     Collaborator may be designated as Proprietary/Confidential Information when
     they are wholly separable from the Subject Data and Research Materials
     developed jointly with PHS investigators, and advance designation of such
     data and material categories is set forth in the RP. 'Me exchange of other
     confidential information, e.g., patient-identifying data, should be
     similarly limited and treated. Jointly developed Subject Data and Research
     Material derived from the

                                NHGRI-Sequenom

<PAGE>

     Research Plan may be disclosed by Collaborator to a third party under a
     confidentiality agreement for the purpose of possible sublicensing pursuant
     to the Licensing Agreement and subject to Article 8.7.

8.5  Protection of Proprietary/Confidential Information.
     Proprietary/Confidential Information shall not be disclosed, copied,
     reproduced or otherwise made available to any other person or entity
     without the consent of the owning Party except as required under court
     order or the Freedom of information Act (5 U.S.C. 1 552). Each Party agrees
     to use its best efforts to maintain the confidentiality of
     Proprietary/Confidential Information. Each Party agrees that the other
     Party is not liable for the disclosure of Proprietary/Confidential
     Information which, after notice to and consultation with the concerned
     Party, the other Party in possession of the Proprietary/Confidential
     Information determines may not be lawfully withheld, provided the concerned
     Party has been given an opportunity to seek a court order to enjoin
     disclosure.

8.6  Duration of Confidentiality Obligation.  The obligation to maintain the
     confidentiality of Proprietary/Confidential Information shall expire at the
     earlier of the date when the information is no longer Proprietary
     Information as defined in Article 2.7 or three (3) years after the
     expiration or termination date of this CRADA.  The Collaborator may request
     an extension to this term when necessary to protect
     Proprietary/Confidential Information relating to products not yet
     commercialized.

8.7  Publication.  The Parties are encouraged to make publicly available the
     results of their research.  Before either Party submits a paper or abstract
     for publication or otherwise intends to publicly disclose information about
     a Subject Invention, Subject Data or Research Materials, the other Party
     shall be provided thirty (30) days to review the proposed publication or
     disclosure to assure that Proprietary/Confidential Information is
     protected.  The publication or other disclosure shall be delayed for up to
     thirty (30) additional days upon written request by any Party as necessary
     to preserve U.S. or foreign patent or other IP rights.

     CRADA, or portions thereof, at any time by mutual written consent. In such
     event the Parties shall specify the disposition of all property,
     inventions, patent or other EP applications and other results of work
     accomplished or in progress, arising from or performed under this CRADA,
     all in accordance with the rights granted to the Parties under the terms of
     this Agreement.

10.2 Unilateral Termination. Either PHS or the Collaborator may unilaterally
     terminate this entire CRADA at any time by giving written notice at least
     thirty (30) days prior to the desired termination date, and any rights
     accrued in property, patents or other IP rights shall be disposed of as
     provided in paragraph 10.1.

10.3 Staffing. If this CRADA is mutually or unilaterally terminated prior to its
     expiration, funds will nevertheless remain available to PHS for continuing
     any staffing commitment made by the Collaborator pursuant to Article 5.1
     above and Appendix B, if applicable, for a period of six (6) months after
     such termination. If there are insufficient funds to cover this expense,
     the Collaborator agrees to pay the difference.

10.4 New Commitments. No Party shall make new commitments related to this CRADA
     after a mutual termination or notice of a unilateral termination and shall,
     to the extent feasible, cancel all outstanding commitments and contracts by
     the termination date.

10.5 Termination Costs. Concurrently with the exchange of final reports pursuant
     to Articles 4.2 and 5.2, PHS shall submit to the Collaborator for payment a
     statement of all costs incurred prior to the date of termination and for
     all reasonable termination costs including the cost of returning
     Collaborator property or removal of abandoned property, for which
     Collaborator shall be responsible.

Article 11.  Disputes

11.1 Settlement. Any dispute arising under this CRADA which is not disposed of
     by agreement of the Principal Investigators shall be submitted jointly to
     the signatories of this CRADA. If the signatories are unable to jointly
     resolve the dispute within thirty (30) days after notification thereof, the
     Assistant Secretary for Health (or his/her designee or successor) shall
     propose a resolution. Nothing in this Article shall prevent any Party from
     pursuing any additional administrative remedies that may be available and,
     after exhaustion of such administrative remedies, pursuing all available
     judicial remedies.

2)   DETAILED DESCRIPTION OF THE CRADA RESEARCH PLAN

A.   IDRB Research Plan: Background and Significance

          "Genetic factors appear to contribute to virtually every human
       disease. Multiple genes and environmental factors influence most common
       diseases. A dense map of DNA sequence variants should allow the
       identification of alleles associated with disease, even for these complex
       diseases."[1]

          SNP stands for "single nucleotide polymorphism. SNPs are the most
       common genetic variations and occur once every 100 to 300 bases. A key
       aspect of research in genetics is the association of sequence variation
       with heritable phenotypes. It is expected that SNPs will accelerate the
       identification of disease genes by allowing researchers to look for
       associations between a disease and specific differences (SNPs) in a
       ------------
       population. This differs from the more typical approach of pedigree
       analysis, which track transmission of a disease through a family. It is
       much easier to obtain DNA samples from a random set of individuals in a
       population than it is to obtain them from every member of a family over
       several generations."[2]

          The importance of using SNPs for identifying DNA variations associated
       with disease is underscored by the NHGRI SNP initiative. Anonymized DNA
       and cell lines from 450 individuals from various ethnic backgrounds are
       being made available for SNP discovery efforts. Researchers who discover
       SNPs are encouraged to place the sequence information in the public
       domain in the NCBI SNP database [3].

          "Once discovered, these polymorphisms can be used by additional
     laboratories, using the sequence information around the polymorphism and
     the specific experimental conditions."[2]

     A number of public databases are already in operation, including NCBI's
dbSNP, (4360 SNPs as of April 1999), University of Uppsala's HgBase (3220 SNPs
as of 3/3/99) and the University of Washington (unknown number of SNPs as of May
1, 1999).

     In order to make SNP genotyping possible on a large-enough scale to allow
genome-wide association studies, assays need to be developed that allow the
genotyping to be done in a massively parallel manner. Genotyping one locus per
individual is not compatible with the need to carry out the tens of thousands of
genotypes per individual in a sample of perhaps hundreds of individuals with a
particular phenotype and an equal number of controls.

     SNP genotyping technology is a rapidly moving field with many methods being
developed and tested. One promising method is to harness the precision of mass
spectroscopy (MS) to detect the sequence variants represented by SNPs (see also
Figure I). MS provides a rapid, highly discriminating, and automatable detection
system that requires very small amounts of input DNA. The disadvantage of MS is
that only one sample can be assayed at one time (although in quick succession).
To make mass spectroscopy assays parallel; it is necessary first to design
assays so that multiple loci can be assayed at one time in such a way that the
alleles generated by the different loci are easily discriminated. Second, the
upfront processing of DNA for mass spectroscopy genotyping needs to be
multiplexed so that multiple loci can be processed for MS assay.

     Sequenom has already developed considerable expertise in designing primers
that allow discrimination by mass spectroscometry (MS) of oligonucleotides whose
length (and therefore mass) differ just sufficiently to allow robust,
unequivocal determination of genotypes (see also http://www.sequenom.com). The
design of these assays is now done routinely but on an ad hoc basis, one assay
at a time, without attention to how multiplexing the PCR of loci and
multiplexing the MS detection could lead to interference between
oligonucleotides. PCR failures, or inability of MS to resolve alleles occurring
at different loci.

                                      ***

     As more and more SNPs enter the public domain and more SNP assays are
developed that rely on MS to detect the alleles, reliable software is needed to
automatically scan new loci as they come along and to design primers and assays
in a way that attempts to maximize our ability to multiplex the PCR and the
allele detection in the context of a large and growing body of already existing
multiplexed assays. With tens of thousands of SNPs becoming available, the
ability to add new loci to increase map density will quickly outstrip any design
method that does not rely on computerized algorithms.

     IDRB can easily assay SNPs one locus at a time using any number of
techniques, including single nucleotide extension, allele specific
oligonucleotide hybridization, allele specific restriction enzyme digestion.
These approaches are generally cumbersome, in that they require gel
electrophoresis, are difficult to automate, and are often difficult to
multiplex. The MassArray instrument, applied to multiplexed oligonucleotide
extension reactions, will allow high automated, high throughput genotyping. One
instrument, fed with appropriately multiplexed reactions, could easily generate
greater than 4 million genotypes per year at a fraction of the labor costs now
required to set up electrophoretic instruments and clean the data coming out of
electrophoretic assays. DNA MassArray(TM) is a platform technology that is
proprietary to the Collaborator and it will be utilized to carry out the CRADA
Research Plan. Improvements, upgrades and/or derivatives of the MassArray(TM)
instrument itself (excluding software) are not within the scope of this CRADA
Research Plan and therefore remain the property of Sequenom.

B. GMBB Research Plan: Background and Significance

The Finland-United States Investigation of non-insulin dependent diabetes
mellitus (NIDDM) FUSION project was initiated five years ago to search for genes
conferring susceptibility to Type 2 diabetes. The FUSION project is being
conducted in the GMBB. Families have been collected in Finland because of the
limited founder pool of that country, as well as the superb medical records
system. In Phase 1 of this study, clinical collaborators, led by Dr. Jaakko
Tuomilehto, have collected 2,500 DNA samples, including 716 affected sibling
pairs and a number of unaffected relatives. Detailed phenotyping has been
carried out on both the affecteds and unaffecteds, allowing determination of
various parameters of insulin metabolism, obesity, blood pressure, and a variety
of other potentially linked phenotypes. The study design has been published
(Diabetes Care 1998: 21:949-958). A follow up set ("FUSION II") of an additional
2,500 DNA samples has now been collected. This includes a replication study as
well as useful extensions of the initial families.

A 10cM genome scan, using microsatellite markers, has been carried out on the
initial 2,500 DNA samples, and sophisticated statistical genetic analyses have
been carried out to look for evidence of diabetes susceptibility genes or other
related quantitative traits. The most promising findings occur on chromosome 20,
where there is evidence for two and possibly three susceptibility genes
(Proceedings of National Academy of Sciences USA 1999; 96:2198-2203). Other
interesting regions occur on chromosomes 1, 3, 10 and 11.

As with all studies on polygenic disease, the challenge is now to go from these
encouraging indications of linkage to the actual responsible gene and the
variant within that gene which confers susceptibility.  Using a variety of
statistical methodologies, it has been possible to narrow the three most
interesting regions on chromosome 20, and the best region on chromosome 11, to
roughly five centiMorgans each. One centiMorgan corresponds to roughly one
million base pairs. One can anticipate that the diabetes susceptibility gene
may be travelling on a discernable haplotype that extends across tens (or
possibly hundreds) of kilobases.

                                      ***

Based on our early unpublished data on linkage disequilibrium in Finland, we
believe that 100 SNPs in an interval of 5 centiMorgans (corresponding roughly to
a spacing of 50 kilobases) should be sufficient to discern a haplotype if one
exists. This would amount to a total of 400 SNPs. Fortunately, with the rapid
progress of the human genome project, SNPs are becoming available across the
genome, although not quite at this density. However, it is anticipated that
those will be appearing, and efforts will also be made by the FUSION group to
derive new ones in our area of greatest interest.

In addition to these localized efforts, which are guided by our own linkage
results, numerous examples of variations in candidate genes are coming to light.
It is important to test each of those to see whether they confer some degree of
susceptibility to diabetes or a related trait. We would expect as many as 100
candidate gene variants to appear over the next 12 months.

Thus we anticipate the need to type a total of 500 single nucleotide
polymorphisms over the next 12-18 months. Each of these, in order to be
optimally evaluated, would need to be tested against roughly 600 to 800 DNA
samples, these being carefully chosen from the complete FUSION set in order to
maximize the likelihood of success without carrying out an unnecessarily large
amount of genotyping.

The Sequenom mass spectrometry assay for SNPs is a particularly attractive
platform for carrying out this analysis, given the potential for very low error
rate and high throughput. If multiplexing of up to 10 SNPs in one tube can be
accomplished, the attractiveness of the system will be even greater. In many
ways, the goals of this collaborative effort are similar and synergistic with
the research plan described by Dr. Nussabaum (IDRB), which aims to develop and
test roughly 3,000 SNPs across the genome. GMBB's somewhat more modest effort,
targeted at 500 SNPs, would emphasize particular candidate regions for diabetes.

3)   RESPECTIVE CONTRIBUTIONS OF THE PARTIES

NHGRI Contributions (both IDRB and GMBB laboratories):

1.   Development of PCR assays and internal oligonucleotide assays for 3000 SNPs
     distributed throughout the genome.
2.   Technology transfer of oligonucleotide sequences used for contribution (1)
     above.
3.   Development of software to automate oligonucleotide design to allow
     multiplex assays and multiplex PCR so that many DNA samples can be
     processed and assayed in parallel.
4.   Personnel dedicated to the IDRB project:

     Principal investigator (15%), four FTE (100%) positions. These include two
     molecular biologist laboratory scientists, one computer programmer, and one
     mass spectroscopist.

     Personnel dedicated to the GMBB project: Two FTE (100% positions).

Sequenom Contributions:

1.   Technology transfer (advice on reagents, etc.) for internal oligonucleotide
     assays including previous experience with oligonucleotide design and
     software programs for running pipetting robots used in sample preparation
     and handling.
2.   Use of a DNA MassArray(TM) Basic System: a modular, semi-automated system
     made up of a proprietary matrix (a miniaturized DNA array called the
     SpectroChip(TM)) and nanospotter technology to prepare samples for matrix
     assisted laser desorption ionization (MALDI) mass spectrometry analysis of
     mixtures of oligonucleotides.
3.   Provide expert advice and consultation on optimum primer design. The
     company's expertise in this area, which can only be obtained by first-hand
     experience in designing these assays specifically for MS, will be necessary
     in order to optimize multiplexing while still insuring robust, high-
     resolution discrimination of alleles at multiplexed loci.

4)  ABSTRACT OF THE RESEARCH PLAN FOR PUBLIC RELEASE

This is a two-way CRADA between two NHGRI laboratories (IDRB and GMBB) and
Sequenom, Inc. to develop SNP genotyping assays suitable for mass spectroscopy
such that multiple loci can be genotyped in parallel.  The IDRB aims to develop
and test approximately 3,000 SNPs across the genome whereas the GMBB's main goal
is to identify and test approximately 500 SNPs targeted in candidate regions for
diabetes. Publicly available anonymous and intragenic polymorphisms may be
targeted for assay development.

                                  APPENDIX C

                   EXCEPTIONS OR MODIFICATIONS TO THIS CRADA

1)   Modify the definition of 2.10 Subject Invention by adding ***. Furthermore
     it is understood that DNA MassArray(TM), defined as nucleic acid analysis
     from arrays by mass spectrometry, which includes existing processes,
     methods, instrumentation that are proprietary to the Collaborator, is a
     platform technology that will be utilized to carry out the Research Plan."
     to the end of the first sentence.

     Paragraph 2.10 reads as follows:

     2.10 "Subject Invention" means any Invention of the Parties, conceived or
          first actually reduced to practice in the performance of the Research
          Plan of this CRADA, ***. Furthermore it is understood that DNA
          MassArray(TM), defined as nucleic acid analysis from arrays by mass
          spectrometry, which includes existing processes, methods,
          instrumentation that are proprietary to the Collaborator, is a
          platform technology that will be utilized to carry out the Research
          Plan.

2)   Within Article 6 Patent Applications add new subarticles 6.2 Collaborator
     Employee Inventions, 6.3 PHS Employee Inventions and 6.4 Joint Inventions.
     Renumber all subsequent subparagraphs of Paragraph 6 (e.g., 6.2-6.4
     renumbered as 6.5-6.7, respectively).

     6.2  Collaborator Employee Inventions.  Collaborator may elect to retain
          intellectual property rights to each Subject Invention made solely by
          Collaborator employees.  If Collaborator does not elect to retain its
          intellectual property rights, Collaborator shall offer to assign these
          intellectual property rights to the Subject Invention to the other
          Party pursuant to Article 6.5.  If PHS declines such assignment,
          Collaborator may release its intellectual property rights as it may
          determine.

<PAGE>

     6.3  PHS Employee Inventions. PHS on behalf of the U.S. Government may
          elect to retain intellectual property rights to each Subject Invention
          made solely by PHS employees. If PHS does not elect to retain
          intellectual property rights, PHS shall offer to assign these
          intellectual property rights to such Subject Invention to the other
          Party pursuant to Article 6.5. If Collaborator declines such
          assignment, PHS may release intellectual property rights in such
          Subject Invention to its employee inventors pursuant to Article 6.5.

     6.4  Joint Inventions.  Each Subject Invention made jointly by PHS and
          Collaborator shall be jointly owned by the PHS and Collaborator.  If
          any Party decides not to retain its intellectual property rights to a
          jointly owned Subject Invention, it shall offer to assign its rights
          to the other inventing Party pursuant to Article 6.6.  If the other
          Parties declines such assignment, the offering Party may dispose of
          its intellectual property rights as provided in Articles 6.2, 6.3 and
          6.5.

3)   Add the following two sentences to the beginning of Paragraph 6.5 Filing of
     Patent Applications: "It is understood by Collaborator that it is the
     policy of NIH to consider filing patent applications only on discoveries
     where there is a clear demonstration that patent protection and
     commercialization of these discoveries will result in a benefit to the
     public health.  In NIH's view, raw genomic DNA sequence, in the absence of
     demonstrated biological information, lacks demonstrated specific utility
     and therefore such information and/or discoveries are considered
     inappropriate material for patent filing."

     Paragraph 6.5 reads as follows:

     6.5  Filing of Patent Applications. It is understood by Collaborator that
          it is the policy of NIH to consider filing patent applications only on
          discoveries where there is a clear demonstration that patent
          protection and commercialization of these discoveries will result in a
          benefit to the public health. In NIH's view, raw genomic DNA sequence,
          in the absence of demonstrated biological information, lacks
          demonstrated specific utility and therefore such information and/or
          discoveries are considered inappropriate material for patent filing.
          Each party shall be responsible for filing patent or other IP
          applications in a timely manner and at its own expense and after
          consultation with the other Party. The Parties will consult and
          mutually determine a filing strategy for jointly owned subject
          inventions.

4)   In the last sentence of 6.6 Patent Expenses add "or nonexclusive" after
     "Collaborator may waive its exclusive" and before "...license rights on any
     application, patent or other intellectual property grant."

     Paragraph 6.6 reads as follows:

                                NHGRI-Sequenom
                Appendix C--Modifications to PHS 3/15/99 model
                                  Page 2 of 5
<PAGE>

     6.6  Patent Expenses. The Party filing such application generally shall pay
          the expense attendant to the filing of patent or other intellectual
          property applications. If an exclusive license to any Subject
          Invention is granted to Collaborator, Collaborator shall be
          responsible for all past and future out-of-pocket expenses in
          connection with the preparation, filing, prosecution and maintenance
          of any applications claiming such exclusively-licensed inventions and
          any patents or other intellectual property grants that may issue on
          such applications. Collaborator may waive its exclusive or
          nonexclusive license rights on any application, patent or other
          intellectual property grant at any time, and incur no subsequent
          compensation obligation for that application, patent or intellectual
          property grant.

5)   Add the following new second sentence to Article 7.1 Option for
     Commercialization License: "The exclusive commercialization license option
     only applies to DNA MassArray(TM) specific Subject Inventions generated
     under this CRADA."

Article 7.1 now reads as follows:

     7.1  Option for Commercialization License. With respect to Government IP
          rights to any Subject Invention not made solely by the Collaborator's
          employees for which a patent or other IP application is filed, PHS
          hereby grants to the Collaborator an exclusive option to elect an
          exclusive or nonexclusive commercialization license, which is
          substantially in the form of the appropriate model PHS license
          agreement The exclusive commercialization license option only applies
          to DNA MassArray(TM) -specific Subject Inventions generated under this
          CRADA. This option does not apply to Subject Inventions conceived
          prior to the effective date of this CRADA that are reduced to practice
          under this CRADA, if prior to that reduction to practice, PHS has
          filed a patent application on the invention and has licensed it or
          offered to license it to a third party. The terms of the license will
          fairly reflect the nature of the invention, the relative contributions
          of the Parties to the invention and the CRADA, the risks incurred by
          the Collaborator and the costs of subsequent research and development
          needed to bring the invention to the marketplace. The field of use of
          the license will be commensurate with the scope of the RP.

6)   In the first sentence of Article 7.5-Third Party license add the word
     "Collaborator's" after "...or exclusive sublicense to use the invention in"
     and before "licensed field of use on terms that are reasonable under the
     circumstances; or if the Collaborator fails to grant such a license, to
     grant the license itself."

     Article 7.5 reads as follows:


                                NHGRI-Sequenom
                Appendix C--Modifications to PHS 3/15/99 model
                                  Page 3 of 5
<PAGE>

     7.5  Third Party License.  Pursuant to 15 U.S.C. (S) 3710a(b)(1)(B), if PHS
          grants an exclusive license to a Subject Invention made wholly by PHS
          employees or jointly with a Collaborator under this CRADA, pursuant to
          Articles 6.3 and 6.4, the Government shall retain the right to require
          the Collaborator to grant to a responsible applicant a nonexclusive,
          partially exclusive, or exclusive sublicense to use the invention in
          Collaborator's licensed field of use on terms that are reasonable
          under the circumstances; or if the Collaborator fails to grant such a
          license, to grant the license itself.  The exercise of such rights by
          the Government shall only be in exceptional circumstances and only if
          the Government determines (i) the action is necessary to meet health
          or safety needs that are not reasonably satisfied by Collaborator,
          (ii) the action is necessary to meet requirements for public use
          specified by Federal regulations, and such requirements are not
          reasonably satisfied by the Collaborator; or (iii) the Collaborator
          has failed to comply with an agreement containing provisions described
          in 15 U.S.C. 3710a(c)(4)(B).  The determination made by the Government
          under this Article is subject to administrative appeal and judicial
          review under 35 U.S.C. 203(2).

7)   Add the following three sentences to the end of Article 8.1 Right of
     Access: "The Parties agree that DNA sequence information (such as SNPs and
     related genotype and/or phenotype information), associated research
     reagents, methodologies and/or data previously generated by NIH, or newly
     generated under this CRADA by NIH, are Research Resources.  NIH reserves
     the right to distribute such resources and researches tools to others and
     use them for their own purposes.  The Parties further agree that data
     generated by any Party through the use of such Research Resources with
     anyone other than the Parties to this Agreement does not constitute Subject
     Data."

     Article 8.1 now reads as follows:

     8.1  Right of Access. PHS and the Collaborator agree to exchange all
          Subject Data produced in the course of research under this CRADA.
          Research Materials will be shared equally by the Parties to the CRADA
          unless other disposition is agreed to by the Parties. The Parties
          agree that DNA sequence information (such as SNPs and related genotype
          and/or phenotype information), associated research reagents,
          methodologies and/or data previously generated by NIH, or newly
          generated under this CRADA by NIH, are Research Resources. NIH
          reserves the right to distribute such resources and researches tools
          to others and use them for their own purposes. The Parties further
          agree that data generated by any Party through the use of such
          Research Resources with anyone other than the Parties to this
          Agreement does not constitute Subject Data.

8)   In the last sentence of 8.2 Ownership of Subject Data and Research
     Materials add "...except that any Research Resources and/or data generated
     under this CRADA are subject to NIH's right to distribute them to others
     and use them for its own purposes"

                                NHGRI-Sequenom
                Appendix C--Modifications to PHS 3/15/99 model
                                  Page 4 of 5
<PAGE>

     after "Jointly developed Subject Inventions, Subject Data and Research
     Materials will be jointly owned."

     Article 8.2 reads as follows:

     8.2  Ownership of Subject Data and Research Materials. Subject to the
          sharing requirements of Paragraph 8.1 and the regulatory filing
          requirements of Paragraph 8.3, the producing Party will retain
          ownership of and title to all Subject Inventions, all Subject Data and
          all Research Materials produced solely by their investigators. Jointly
          developed Subject Inventions, Subject Data and Research Materials will
          be jointly owned except that any Research Resources and/or data
          generated under this CRADA are subject to NIH's right to distribute
          them to others and use them for its own purposes.

9)   In the first sentence of 8.6 Duration of Confidentiality Obligation change
     the term from three (3) years to five (5) years.

     Article 8.6 reads as follows:

     8.6  Duration of Confidentiality Obligation. The obligation to maintain the
          confidentiality of Proprietary/Confidential Information shall expire
          at the earlier of the date when the information is no longer
          Proprietary Information as defined in Article 2.7 or five (5) years
          after the expiration or termination date of this CRADA. The
          Collaborator may request an extension to this term when necessary to
          protect Proprietary/Confidential Information relating to products not
          yet commercialized.

                           CONFIDENTIALITY AGREEMENT

Under tile terms of tile Consulting Agreement, the Consultant is under
obligation not to disclose any business information or Company secrets to
unauthorized parties and/or to persons outside the Company.

Maintaining confidentiality is a constituent part of the Consultant's loyalty to
the Company and protects business and Company secrets.  Company secrets are data
and materials identified as confidential or those which, upon careful
consideration, a Consultant can recognize as being confidential (e.g. technical
expertise, even if not patentable, supply sources for goods, customer lists,
price schedules, calculations, investment plans, etc., including also the
Consultant's own inventions made in the performance of the Consulting Agreement.

Details of any production or analytical methods of which the Consultant may gain
knowledge and regarding which the Company as license holder is committed to
maintain strictest confidentiality are also classified as secret.  This applies
to details of production processes to which the Company has gained access in the
course of an exchange of know-how with another Company or which are classified
secret by the Company under its commitment to confidentiality with another
Company.

The Consultant further undertakes to maintain strictest confidentiality
regarding all matters of the Company's business also after termination of the
Consulting Agreement.  In this context the Consultant is obliged, if so
required, to sign a respective personal commitment to confidentiality vis-a-vis
third parties.

In the event of any violation of this Agreement to confidentiality, the Company
is entitled to impose a penalty for each violation, without prejudice to the
Company's right to claim for higher damages, or the Company's right to
termination of the Consulting Agreement.

Consultant retains the right to publish results obtained as a result of or in
connection with the services delivered under this Agreement.  Consultant shall
inform Company about intended publications at the earliest convenience and shall
provide Company with all relevant material, in particular draft manuscripts.
Company may delay publication by a maximum of three months if all or part of the
material is deemed to contain patentable material or material which can be
legally protected by other means.  Consultant shall provide Company with all
available material necessary to file for such rights.  In case of other tangible
information, both parties will make every reasonable effort to limit the
published information so as not to interfere with the justified commercial
interest of the Company under the provision that the scientific content of the
publication be retained.

                           CONFIDENTIALITY AGREEMENT

Under the terms of the Consulting Agreement, the Consultant is under obligation
not to disclose any business information or company secrets to unauthorized
parties and/or to persons outside the Company.

Maintaining confidentiality is a constituent part of the Consultant's loyalty to
the Company and protects business and company secrets.  Company secrets are data
and materials identified as confidential or those which, upon careful
consideration, a Consultant can recognize as being confidential (e.g. technical
expertise, even if not patentable, supply sources for goods, customer lists,
price schedules, calculations, investment plans, etc., including also the
Consultant's own inventions made in the performance of the Consulting Agreement.
This agreement to confidentiality is deemed to extend and apply also to any co-
workers involved in the execution of the collaboration project with the Company.

Details of any production or analytical methods of which the Consultant may gain
knowledge and regarding which the Company as license holder is committed to
maintain strictest confidentiality are also classified as secret.  This applies
to details of production processes to which the Company has gained access in the
course of an exchange of know-how with another company or which are classified
secret by the Company under its commitment to confidentiality with another
company.

The Consultant further undertakes to maintain strictest confidentiality
regarding all matters of the Company's business also after termination of the
Consulting Agreement.  In this context the Consultant is obliged, if so
required, to sign a respective personal commitment to confidentiality vis-a-vis
third parties.

In the event of any violation of this agreement to confidentiality, the Company
is entitled to impose a penalty for each violation, without prejudice to the
Company's right to claim for higher damages, or the Company's right to
termination of the Consulting Agreement.

                           CONFIDENTIALITY AGREEMENT

Under the terms of the Consulting Agreement, the Consultant is under obligation
not to disclose any business information or company secrets to unauthorized
parties and/or to persons outside the Company.

Maintaining confidentiality is a constituent part of the Consultant's loyalty to
the Company and protects business and company secrets.  Company secrets are data
and materials identified as confidential or those which, upon careful
consideration, a Consultant can recognize as being confidential (e.g. technical
expertise, even if not patentable, supply sources for goods, customer lists,
price schedules, calculations, investment plans, etc., including also the
Consultant's own inventions made in the performance of the Consulting Agreement.

Details of any production or analytical methods of which the Consultant may gain
knowledge and regarding which the Company as license holder is committed to
maintain strictest confidentiality are also classified as secret.  This applies
to details of production processes to which the Company has gained access in the
course of an exchange of know-how with another company or which are classified
secret b the Company under its commitment to confidentiality with another
company.

The Consultant further undertakes to maintain strictest confidentiality
regarding all matters of the Company's business also after termination of the
Consulting Agreement.  In this context the Consultant is obliged, if so
required, to sign a respective personal commitment to confidentiality vis--vis
third parties.

In the event of any violation of this agreement to confidentiality, the Company
is entitled to impose a penalty for each violation, without prejudice to the
Company's right to claim for higher damages, or the Company's right to
termination of the Consulting Agreement.
