                               PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in this prospectus.
It may not contain all of the information investors should consider before
investing in the common stock of EST. Investors should read the entire
prospectus carefully.

                       Embedded Support Tools Corporation

   We design, manufacture, sell and support integrated hardware and software
tools for programming, testing and debugging embedded systems. Our products
enable developers to quickly and reliably program and debug the embedded
systems that manufacturers build into their industrial and consumer products.
As the complexity and speed of embedded systems increase, we believe that
embedded systems developers will require more efficient solutions to program
their products and that we are well positioned to offer these solutions.

   A significant portion of our customers are in the communications industry,
including telecommunications, data communications and Internet infrastructure
equipment suppliers. Our largest customers by revenue include Hewlett-Packard,
Lucent Technologies, Motorola, Nortel Networks, Tellabs Wireless and 3Com.

   We were incorporated in Massachusetts in 1989. Our principal executive
offices are located at 120 Royall Street, Canton, Massachusetts 02021 and our
telephone number is (781) 828-5588. Our World Wide Web site address is
www.estc.com. The information contained on our Web site is not part of this
prospectus.

                             Our Market Opportunity

   Embedded systems are the special purpose computers within intelligent
industrial and consumer products such as network switches and routers, cellular
base stations, process control systems, cell phones, printers and anti-lock
braking systems. As with all computers, embedded systems minimally consist of a
microprocessor, memory and software, and the level of complexity of that system
can be enhanced with additional components. Embedded systems differ from
general purpose computers, such as PCs, workstations and mainframes, in that
they are designed to run only the specific set of tasks required for the end
product to operate as intended. Manufacturers use embedded systems to enhance
functionality and performance, reduce cost and size, and improve reliability of
a broad variety of products, ranging from simple systems found in microwave
ovens to complex multiprocessor driven systems controlling the infrastructure
of the Internet. Embedded systems development tools enable the developer to
edit and compile code, transfer the operating system and application software
to the microprocessor, and test and debug the program and the functionality of
the embedded system as a whole.

   According to industry and market research firms, at least 55% of the more
than 265 million microprocessors produced by the semiconductor industry in 1998
were used in embedded systems, while the remainder were used in general purpose
computers such as PCs. We participate in the market for the higher-end 32-bit
and greater embedded microprocessors, which is forecast to grow at a rate of
21%, from 106 million units in 1998 to 228 million units in 2002. Motorola is
the largest supplier of embedded microprocessors, with a market share of 35% in
1997, the latest year for which data is available. The market for embedded
software development tools is part of the overall embedded operating systems
and development tools market, which was approximately $550 million in 1998 and
is forecast to grow 14% annually through 2003.

                                  Our Solution

   We design, manufacture, sell and support a comprehensive suite of high
performance, open and scalable embedded systems development tools, consisting
of both hardware and software components. Our tools enable development
engineers to program, test and debug embedded systems quickly and reliably at
each stage of the development process. We believe that our leadership position
arises from the following:

  Superior Development Tools - Our tools offer the following advantages:

  .  Bundled - We bundle software debuggers and other graphical utilities
     with hardware tools to produce a complete solution for early stage
     hardware and firmware development;

  .  Open - We enable developers using our tools to incorporate a variety of
     real-time operating systems into their products and to use a wide range
     of software tools with our hardware products;

  .  Graphical - Our software tools provide a rich graphical user interface,
     which gives programmers easy access to multiple in-depth views of
     microprocessor data and development status; and

  .  Scalable - Our hardware tools are modular and designed to easily allow
     developers to configure and scale their development environments to meet
     their specific needs.

  Microprocessor Knowledge Base - We were one of the first companies in the
  industry to develop and market tools for debugging Motorola microprocessors
  using its on-chip debug capabilities. We have been able to adapt our tools
  to work with over 50 different microprocessors within the Motorola and IBM
  families. Through our relationships with Motorola and IBM, we gain early
  access to new microprocessor designs prior to commercial release.

  Comprehensive Customer Support - We deploy a team of 41 field salespeople
  and support engineers to assist our customers throughout the development
  process. This support includes providing early development kits containing
  single board computers and board support packages. We also offer our
  customers formal one-day and three-day training sessions on microprocessor
  architectures.

                                  Our Strategy

   Our goal is to maintain and enhance our position as a technological and
market leader in embedded systems development tools. In order to achieve this
goal, we intend to:

  Extend Our Technological Leadership - We have established leadership in
  development tools by bundling hardware and software solutions, and we must
  insure that our products continue to embody the latest technologies and
  features.

  Continue Our Focus on Communications Applications - A significant number of
  our customers build highly complex data communications, telecommunications
  and Internet networking equipment. We plan to expand our product offerings
  to address the specific needs of developers by leveraging our strengths
  within these markets.

  Increase Our Software Product Offerings - We intend to use our strengths in
  the hardware bring-up development stage to extend and enhance our software
  solutions, while remaining operating system independent.

  Satisfy Customer Demand for Additional Microprocessor Architectures - Our
  tools work with more than 50 different microprocessors from Motorola and
  IBM. We intend to meet the needs of our customers by continuing to adapt
  our development tools for an even wider range of microprocessor
  architectures.

  Strengthen and Develop Strategic Alliances - We have developed significant
  relationships with Motorola and Wind River Systems, and we intend to
  strengthen these relationships as well as seek new alliances.

                      Summary Consolidated Financial Data

   EST has been treated as a Subchapter S corporation for federal income tax
purposes since its organization on January 5, 1989. As a Subchapter S
corporation, EST has not been subject to federal and certain state income
taxes. The pro forma net income (loss) reflects the provision for income taxes
that would have been recorded had EST been a Subchapter C corporation, assuming
an effective tax rate of 40%, 32%, 34%, 40%, and 11% for the years ended
December 31, 1995, 1996, 1997, 1998 and 1999, respectively. See Notes 2 and 10
of Notes to Consolidated Financial Statements.

   Pro forma as adjusted balance sheet data set forth below reflects the
distribution of an estimated $4.6 million of cumulative undistributed
Subchapter S corporation taxable income for which stockholders of record prior
to the closing of this offering have been taxed. The distribution will be made
out of the net proceeds of this offering. The pro forma as adjusted balance
sheet data also reflects the sale of 4,100,000 shares of common stock by EST at
an assumed initial public offering price of $11.00 per share, after deducting
the underwriting discounts and commissions and estimated offering expenses
payable by EST.

                                  RISK FACTORS

   You should carefully consider the following risk factors, in addition to the
other information in this prospectus, before purchasing shares of EST common
stock. Each of these risk factors could adversely affect our business,
operating results and financial condition as well as adversely affect the value
of an investment in our common stock and could cause you to lose some or all of
your investment. This offering involves a high degree of risk.

   Risks Related To Our Business

   If Motorola microprocessor sales are disrupted or decline for any reason our
   business would suffer since we derive substantially all of our revenues from
   customers who use Motorola microprocessors.

   We have designed our tools to work principally with embedded systems using
Motorola microprocessor architectures. To date, substantially all of our
revenues have come from customers who use Motorola microprocessors in their
embedded systems. We would be harmed if Motorola microprocessor sales are
interrupted for any reason or if embedded systems developers who use our tools
choose another microprocessor family. We are in the process of creating
development tools to be used with microprocessors made by manufacturers in
addition to Motorola. If we are unsuccessful in developing tools that work with
microprocessors other than Motorola microprocessors, we may fail to grow our
business and our revenues may decline.

   Our success is dependent upon early access to Motorola microprocessor
   designs and product information and we could lose significant revenue if our
   early access to such information from Motorola is interrupted for any
   reason.

   As part of our relationship with Motorola, our engineers communicate with
their counterparts at Motorola and have early access to new microprocessor
designs. With this knowledge, we are able to adapt our tools to these new
designs and make our tools available at the time our customers begin to
incorporate new Motorola microprocessor releases into their product designs.
Our relationship with Motorola is not the subject of any written agreement and
it is not exclusive.

   If Motorola expands its operations to become a direct source of development
   tools to a broad range of embedded systems developers our revenues and
   profits could be negatively impacted.

   Motorola has traditionally relied on third-party vendors to provide tools
for its microprocessors. Motorola recently acquired Metrowerks, a maker of
software-only tools. If Motorola expands its operations to include selling
development tools to a broad range of embedded systems developers, our revenues
and profits could be negatively impacted.

   We believe our relationship with Wind River, which entails a collaborative
   effort in the marketing and selling of our respective products will be
   discontinued and such discontinuation could significantly harm our business.

   Wind River Systems is a major provider of operating systems and development
tools. Currently, we collaborate with Wind River in marketing and selling our
respective product offerings. However, Wind River recently acquired Integrated
Systems, another provider of operating systems and development tools. We
believe this acquisition will likely affect our relationship with Wind River,
as Wind River will expand its product offerings to actively market and sell
development tools similar to the products we offer. Any interruption of our
relationship would likely cause significant harm to our business.

   Intense competition in our industry may result in price reductions, reduced
   gross margins and loss of market share, and in turn may hurt our business
   and ability to compete successfully.

   The embedded systems development tools market is rapidly evolving and
intensely competitive. Competition could intensify even further if
microprocessor manufacturers were to enter into our marketplace.

                                       8
<PAGE>

Competitors may develop and offer products and services similar to ours in the
future. Our business would be harmed if we are not able to compete
successfully against current or future competitors. Although we believe that
there are market opportunities for several providers of products and services
similar to ours, a single provider might obtain a dominant position. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share, any of which could harm our business. A number of our
current and potential competitors have longer operating histories, larger
customer bases, greater brand recognition and significantly greater financial,
marketing, technical and other resources than we do. Our competitors may be
able to devote significantly greater resources to marketing campaigns, adopt
more aggressive pricing policies and may expend substantially more resources
on product development. If we do not compete effectively, our revenues and
earnings may suffer.

   If we lose the services of any of our key personnel, our ability to develop
   new products, service our customers or expand our operations could be
   impeded.

   In order to continue to provide quality services in our rapidly changing
business, we believe it is particularly important to retain personnel with
experience. Our business depends in large part on the continued service of a
number of key employees, including Peter Dawson, our President and Chief
Executive Officer, and James Watkins, our Chief Operating Officer and Senior
Vice President of Sales and Marketing. The loss of the services of Mr. Dawson,
Mr. Watkins or any of our other key personnel could seriously impede our
success. Our employees, other than Messrs. Dawson, Watkins, Lossky and
McGillivray, are not subject to employment contracts and are free to leave us
at any time. We might not be able to prevent key personnel, who may leave our
employ in the future, from disclosing or using our technical knowledge,
practices and procedures. One or more of our key employees could join a
competitor or form a competing company. Losing the services of one or more of
our key employees could impede our ability to develop new products, service
our customers or expand our operations.

   There is intense competition for qualified engineers and sales and
   marketing personnel, and our failure to recruit, retain and motivate such
   skilled employees could affect our ability to increase our sales.

   Our failure to attract and retain qualified employees could impair our
ability to grow our business. In order to maintain and increase our market
share, we must be able to hire, train, and retain and manage highly skilled
employees. To date, we have been successful in meeting our requirements for
highly skilled sales and support personnel and research and development
engineers. However, competition for such engineers is intense and likely to
become more so in the future. If our operations continue to grow, it may
become more difficult to recruit, train and retain skilled engineers and
managers. Failure to attract and retain qualified employees will impede our
ability to develop new products and service our customers and expand our
operations.

   If our customers' new products do not use microprocessors for which we
   supply development tools, we will lose significant sales in the future.

   We do not provide development tools for many microprocessor families used
in embedded systems. Our success depends on our customers selecting
microprocessors that we provide development tools for as the standard for new
generations of their products. If our customers do not use these
microprocessors, our future sales would be reduced.

   If customers are late in commencing their product development cycles, our
   short-term revenues would be negatively affected.

   Developers generally buy our development tools at the beginning of a
product development cycle. If a customer delays its product development cycle,
it will likely also postpone the purchase of our development tools. Such a
delay could cause a decline in our short-term revenues. There are many reasons
why a particular customer's project might experience delays. For example, the
customer's own design process could be slowed by technical problems or
unavailability of personnel.


                                       9

   The unpredictability of our operating results may adversely affect the
   trading price of our common stock.

   We expect that our quarterly and annual operating results will fluctuate
significantly due to many factors, some of which are outside our control,
including:

  . demand for and market acceptance of our products and services;

  . our ability to retain key customers or strategic partners;

  . intense and increased competition;

  . introductions of new products or services, by us and our competitors; and

  . our ability to control our costs.

   Any one or more of these factors could affect our business, financial
condition and results of operations, and this makes any prediction of results
of operations on a quarterly basis unreliable. As a result, we believe that
period-to-period comparisons of our historical results of operations are not
necessarily meaningful and that you should not rely on them as an indication
of future performance. It is possible that our quarterly results of operations
may be below the expectations of public market analysts and investors. This
could cause the price of our common stock to decline substantially.

   Risks associated with our international business operations could impair
   our ability to grow our business.

   A significant portion of our sales are generated outside the United States.
This exposes us to risks such as economic fluctuations in various countries,
longer accounts receivable collection periods, greater difficulty in
collecting accounts receivable, reduced or limited protection for intellectual
property, export license requirements and other trade barriers and potentially
adverse tax consequences. We must employ and retain personnel throughout the
world and employment laws vary widely from country to country. To date, we
have been able to successfully staff our international operations, but if we
continue to grow our operations, it may become more difficult to manage our
business. We may also experience foreign currency fluctuations which could
have a significant impact on our revenues, cash flow and ability to achieve
and maintain profitability as we attempt to grow our business. If we fail to
manage our international operations successfully, our ability to service our
foreign customers and grow our business in these countries will be seriously
impeded.

   We rely on a single source for supply of a circuit board component and our
   business may be harmed if our supply of this component is disrupted.

   We currently purchase a key component (field programmable gate arrays) from
Altera Corporation. We purchase this component as needed and have no long-term
contracts with Altera. Although we believe that there are alternative sources
for this component, switching to another source could require significant re-
engineering and result in product delays. Such a disruption in supply could
hurt our ability to deliver our products to our customers and negatively
affect our operating margins.

   Our customers give us orders for projects at hand rather than for long-term
   requirements. Thus, our failure to obtain and fulfill orders in a quarter
   will hurt our operating result for that period.

   A majority of our revenue is derived from orders relating to a customer's
particular projects rather than long-term contracts. We cannot assure you that
a customer will purchase additional products from us once a project is
completed. A decrease in demand for our products from one or more customers
could occur with limited advance notice and could have a negative impact on
our results of operations in any particular period. In addition, a substantial
portion of our expenses, including most product development and selling and
marketing expenses, must be incurred in advance of revenue generation. If our
revenues do not meet our expectations, then our operating profit, if any, may
fall short of our expectations.

                                      10
<PAGE>

   If we do not respond rapidly to technological changes, our business will
   suffer.

   Our customers are continuously developing new products to compete within
their own markets and are seeking to both shorten the time to market and
improve the quality of their products. In addition, microprocessor technology
is constantly changing and our competitors are constantly improving their
products in response. As a result, we must anticipate and react to changes in
our market, and we cannot assure you that we will be able to respond quickly
or effectively to such developments. The introduction of new products by
competitors, market acceptance of products based on new or alternative
technologies or the emergence of new industry standards could render our
existing or future products obsolete. Our business will suffer if we do not
modify our products or create new ones in order to meet customer needs on a
timely basis and match or surpass the advances in competitive products.

   Expanding our product offerings may strain our ability to manage our
   business.

   We seek continued growth by expanding our product line and extending it to
microprocessor platforms for which we do not currently provide tools. This
effort will:

  . place a significant burden on our management;

  . require our recruiting and retaining additional high-level executives;

  . require the hiring of significantly more engineers;

  . require significant outlays of cash for technically skilled sales persons
    and sales efforts; and

  . strain existing operational systems and controls.

   We may not be able to meet our hiring needs for engineering and management
personnel because of the small number of qualified candidates and the intense
demand for their services. We are unable to assure you that we will be able to
expand our product offerings and, if we do grow, whether we will be able to
expand our managerial and operational infrastructure to manage such expansion
successfully.

   We could become involved in litigation regarding intellectual property
   rights which could seriously harm our business.

   We rely on a combination of patent, copyright, trademark and trade secret
laws and restrictions on disclosure to protect our intellectual property
rights. We also enter into nondisclosure agreements with our employees,
consultants and corporate partners, and control access to our proprietary
information. Litigation may be necessary in order to enforce our intellectual
property rights, to protect our trade secrets, to determine the validity and
scope of the proprietary rights of others or to defend against claims of
infringement. Although we are not aware of any third party intellectual
property rights that would prevent the use and sale of our products, we may
unknowingly infringe the proprietary rights of others. Any infringement could
result in significant liability to us. If we do infringe the proprietary
rights of others, we could be forced to either seek a license to those
intellectual property rights or alter our products so that they no longer
infringe upon other's proprietary rights. Any such license could be very
expensive to obtain or may not be available at all. Similarly, changing our
products or processes to avoid infringing the rights of others may be costly
or impractical. Such litigation could result in substantial costs and
diversion of resources and management's focus.

   Year 2000 non-compliance by our customers, vendors or third parties could
   adversely impact our business.

   Many computers use two-digit date fields to identify a given year. Year
2000 non-compliance is the failure of date sensitive computing systems and
applications to properly recognize and process dates into and after the year
2000. Problems associated with such recognition failures may not become
apparent until some time after January 2000. We believe that our own products
do not contain any date sensitive components. However, we

                                      11
<PAGE>

are unable to evaluate whether our customers', vendors' or third parties'
products are Year 2000 compliant. Purchasing patterns may be affected by Year
2000 issues if our customers are required to expend significant resources to
correct or replace their current systems. These customers and potential
customers may have fewer funds available to purchase our products. Further,
our vendors and suppliers may use computing systems that are not Year 2000
compliant. If a limited or sole source supplier experienced difficulties
relating to their computer system, we may be forced to expend resources in
locating an alternative supplier. In addition, our internal information and
manufacturing systems are dependent upon personal computers using date
sensitive components. If any of these systems were to fail, we may have to
expend financial and managerial resources to correct any problems.

   Our former status as a Subchapter S corporation could expose us to
   liability.

   We elected Subchapter S corporation status under the Internal Revenue Code
from our inception to the completion of this offering. Although we believe
that we met the Subchapter S corporation requirements under the Code during
this period, we have not requested, and the IRS has not made a determination,
as to our status. If the IRS were to challenge our status and determine that
we did not meet the Code requirements for Subchapter S corporations, we could
be liable for unpaid federal and state income taxes for all or a part of the
time that we elected Subchapter S corporation status, plus interest and
possible penalties.

   Risks Related To This Offering

   We are controlled by a small number of stockholders who could make
   decisions that adversely affect other stockholders.

   Peter Dawson, James Watkins and John Baggott will, in the aggregate, hold
57.1% of the outstanding shares of our common stock upon the closing of this
offering, or 55.6% if the underwriters exercise their over-allotment option in
full. As a result of their ownership share, these stockholders will have
significant control over management and operations and will have a significant
influence on all votes requiring stockholder approval, including votes to
amend our Restated Articles of Organization in certain respects or approve a
merger, sale of assets or other major corporate transactions.

   Our stock has never been traded publicly and its price could be volatile,
   which could affect your ability to resell your shares at a profit.

   Prior to this offering, you could not buy or sell our common stock
publicly. An active market for our common stock may not develop or be
sustained after this offering. The stock market has from time to time
experienced significant price and volume fluctuations that have affected the
market prices for the securities of technology companies. As a result, you may
not be able to resell your shares at a price equal to or greater than the
initial public offering price.

   The market price of our common stock may fluctuate significantly in
response to many factors, some of which are beyond our control, including the
following:

  .  actual or anticipated fluctuations in our operating results;

  .  changes in market valuations of other technology companies;

  .  announcements by us or our competitors of significant technical
     innovations, contracts, acquisitions, strategic relationships, joint
     ventures or capital commitments;

  .  termination of a strategic relationship; and

  .  sales of common stock in the future.

                                      12
<PAGE>

   A significant number of shares are restricted from immediate resale but may
   be sold into the market in the near future. This could cause the market
   price of our common stock to drop significantly.

   After this offering, we will have outstanding 16,994,000 shares of common
stock. This includes the 4,500,000 shares we and a selling stockholder are
selling in this offering, all of which may be resold in the public market
immediately. The remaining 12,494,000 shares of our total outstanding shares
are presently restricted but will become available for resale in the public
market as shown below.

   As restrictions on resale end, the market price could drop significantly if
the holders of these restricted shares sell them or are perceived by the
market as intending to sell them.

                  stockholders have with Prudential Securities Incorporated on
                  behalf of the underwriting group. However, Prudential
                  Securities Incorporated can waive this restriction at any
                  time and without notice.

   After the date of this prospectus, we intend to file one or more
registration statements under the Securities Act to register all shares of
common stock issuable upon the exercise of outstanding stock options or
reserved for issuance under our Amended and Restated 1999 Stock Option Plan of
which 652,200 will be immediately exercisable as of April 1, 2000 and 652,200
shares will be exercisable within 60 days of February 1, 2000. Those
registration statements are expected to become effective immediately upon
filing, and subject to the vesting requirements and exercise of the related
options and the grant of stock awards as well as the terms of the lock-up
agreements, shares covered by those registration statements will be eligible
for sale in the public markets, except for any shares held by our
"affiliates."

   Investors in this offering will experience immediate and substantial
   dilution and may experience additional dilution in the future.

   The initial public offering price of our stock is substantially higher than
the net tangible book value per share of our common stock immediately after
this offering. Therefore, if you purchase our common stock in the offering,
you will incur immediate and substantial dilution of approximately $8.76 per
share in the net tangible book value per share of common stock from the price
you pay for a share of common stock in the offering based upon the assumed
initial public offering price of $11.00 per share. In addition, as of December
31, 1999, there were options outstanding to purchase 2,555,500 shares of our
common stock at a weighted average exercise price of $3.27. To the extent any
of these options are exercised, you will suffer dilution greater than the
$8.68 per share described above.

   Our management will have broad discretion in the use of proceeds and they
   may not effectively utilize those funds.

   The primary purposes of this offering are to obtain additional capital,
create a public market for our common stock and facilitate future access to
public markets. We expect to use the net proceeds from this offering for
working capital and other general corporate purposes, including expansion of
our sales staff. Our management will have considerable discretion in the
application of the net proceeds of this offering and you will not have the
opportunity, as part of your investment decision, to assess whether the
proceeds are being used appropriately. Because of the number and variability
of the factors that may determine our use of the net proceeds from this
offering, we cannot assure you that the net proceeds will be used for
corporate purposes that increase our profitability or our market value or that
you will agree with our use of proceeds.

                                      13

   Our charter and Massachusetts law may inhibit a takeover, which may limit
   the price an investor is willing to pay for our common stock.

   Certain provisions of our Restated Articles of Organization and Amended and
Restated Bylaws, and certain provisions of Massachusetts law could have the
effect of making it more difficult for a third party to acquire, or of
discouraging a third party from attempting to acquire, control of EST. Such
provisions could limit the price that investors might be willing to pay in the
future for the EST's common stock. These provisions permit the issuance of
"blank check" preferred stock by the Board of Directors without stockholder
approval, require super-majority approval to amend certain provisions in the
charter and Bylaws and impose various procedural and other requirements that
could make it more difficult for stockholders to effect certain corporate
actions. The application of such provisions also could have the effect of
delaying or preventing a change of control in the Company.

                          FORWARD-LOOKING STATEMENTS

   This prospectus includes forward-looking statements. We have based these
forward-looking statements largely on our current expectations and projections
about future events and financial trends affecting the financial condition of
our business. These forward-looking statements are subject to a number of
risks, uncertainties and assumptions about us, including, among other things:

  . General economic and business conditions, both nationally and in our
    markets,

  . Our expectations and estimates concerning future financial performance,
    financing plans and the impact of competition,

  . Anticipated trends in our business,

  . Competition in our market, and

  . Other risk factors set forth under "Risk Factors" in this prospectus.

   In addition, in this prospectus, the words "believe," "may," "will,"
"estimate," "continue," "anticipate," "intend," "expect" and similar
expressions, as they relate to us, our business or our management, are
intended to identify forward-looking statements.

   We undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or
otherwise. In light of these risks and uncertainties, the forward-looking
events and circumstances discussed in this prospectus may not occur and actual
results could differ materially from those anticipated or implied in the
forward-looking statements.

  SUBCHAPTER S CORPORATION AND TERMINATION OF SUBCHAPTER S CORPORATION STATUS

   We have been treated as a Subchapter S corporation for federal income tax
purposes since we were organized on January 5, 1989. As a result, we have not
been liable for federal and certain state income taxes, and all of our earnings
have been subject to federal, and certain state, income taxation directly at
the stockholder level. Our Subchapter S corporation status will terminate upon
the closing of this offering, at which time we will become subject to corporate
income taxation under Subchapter C of the Internal Revenue Code and applicable
state income taxation law. Pro forma statement of operations data included in
this prospectus have been adjusted to include pro forma income tax provisions
as if we had been a Subchapter C corporation during the relevant periods.

   As soon as practicable following the closing of this offering, we intend to
make a distribution to our stockholders of record on the day prior to the
effective date of the registration statement of $4.6 million, which is the
estimated amount of our cumulative Subchapter S income for the period we were a
Subchapter S corporation (from January 5, 1989 through the date of the closing
of this offering ) minus any distributions made to stockholders during this
period. Investors purchasing shares in this offering will not receive any
portion of the distribution.

   We expect to enter into a Tax Indemnification Agreement with our existing
stockholders providing for, among other things, the stockholders to indemnify
us for any federal and state income taxes, including interest and penalties,
incurred by us if for any reason we are deemed to be treated as a Subchapter C
corporation during any period in which we reported our taxable income as a
Subchapter S corporation. The tax indemnification obligation of each existing
stockholder is limited to the aggregate amount of all distributions made to
such stockholders by us since the first day of the first tax year that we are
deemed to be treated as a Subchapter C corporation. We believe we have met the
requirements for a Subchapter S corporation and the Tax Indemnification
Agreement will provide for payment by our existing stockholders to us and by us
to our existing stockholders to adjust for any increases or decreases in tax
liability arising from a tax audit which affects our tax liability and results
in a corresponding adjustment to the tax liability of our existing
stockholders. The amount of any payment cannot exceed the amount of refund
received from the IRS by us or our existing stockholders attributable to the
adjustment.

                                USE OF PROCEEDS

   We estimate that our net proceeds from the sale of the 4,100,000 shares of
common stock to be sold by us will be approximately $40,943,000 ($45,802,250 if
the underwriters exercise their over-allotment option from us in full),
assuming an initial public offering price of $11.00 per share and after
deducting underwriting discounts and commissions and estimated offering
expenses payable by us. We intend to use these net proceeds for the following
specific purposes:

  . to make a distribution of previously undistributed Subchapter S
    corporation income of approximately $4.6 million;

  . to repay an outstanding balance of $2.4 million on a $2.5 million line of
    credit from BankBoston, N.A., dated as of December 27, 1999. This line of
    credit requires monthly payments of accrued interest to be paid until
    August 31, 2001, at which time all outstanding principal is payable. The
    line of credit accrues interest at an initial rate of 8.25% per annum and
    is collateralized by all of our assets. The purpose of the borrowings
    under the line of credit is to fund payments of taxes to the Internal
    Revenue Service and state taxing authorities incurred by seven key
    employee stockholders, other than the recipients of the $4.6 million
    described above, who were awarded shares of common stock in 1999; and

  . for general working capital purposes.

   We have broad discretion regarding the use of some of the proceeds to us
from this offering. We currently intend to use the remainder of the net
proceeds from this offering for general corporate purposes, including working
capital, product development, the hire of additional engineers and the
expansion of our sales force, and expansion of our international operations. We
may also use a portion of the net proceeds to acquire or invest in
complementary businesses or products or to obtain the right to use
complementary technologies. We have no specific understandings, commitments or
agreements with respect to any such acquisition or investment. Pending these
uses, we plan to invest the net proceeds of this offering in short-term,
interest-bearing, investment-grade securities or guaranteed obligations of the
U.S. government. We will not receive any proceeds from the sales of common
stock by the selling stockholders.

                                DIVIDEND POLICY

   We do not anticipate declaring or paying cash dividends in the foreseeable
future. We currently intend to retain all future earnings, if any, to finance
the expansion of our business. We currently intend, subject to our contractual
obligations under the Tax Indemnification Agreement, to retain earnings for the
expansion and continued development of our business. Our current loan agreement
restricts the payment of dividends without prior written consent. Other
restrictions or limitations on the payment of dividends may be imposed in the
future under the terms of credit agreements or under other contractual
provisions. In the absence of such restrictions or limitations, the declaration
and payment of any dividends will be at the discretion of our Board of
Directors.

                                    DILUTION

   Purchasers of the common stock in the offering will experience immediate and
substantial dilution in the net tangible book value of the common stock from
the initial public offering price. The pro forma net tangible book value per
share represents the amount of the total tangible assets less total
liabilities, divided by the number of shares of common stock outstanding,
including redeemable common stock. At December 31, 1999, we had a pro forma net
tangible book value of approximately $0.7 million or $0.05 per share of common
stock. After giving effect to the sale of 4,100,000 shares of common stock
offered by us at an assumed initial public offering price of $11.00 per share,
the assumed exercise of 2,555,500 options at a weighted average exercise price
of $3.27 per share outstanding at February 2, 2000 and after the deduction of
underwriting discounts and commissions and estimated offering expenses, pro
forma net tangible book value at December 31, 1999 would have been
approximately $45.3 million or $2.32 per share. This represents an immediate
increase in net tangible book value of $2.27 per share to existing shareholders
and an immediate and substantial dilution of $8.68 per share to new investors
purchasing common stock in this offering. The following table illustrates this
per share dilution:

                      SELECTED CONSOLIDATED FINANCIAL DATA

   The following selected consolidated financial data set forth below should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included elsewhere in this prospectus. The
selected consolidated statement of operations data for the years ended December
31, 1997, 1998 and 1999, and the selected consolidated balance sheet data as of
December 31, 1998 and 1999, are derived from and are qualified by reference to
the audited consolidated financial statements included elsewhere in this
prospectus. The consolidated statement of operations data for the years ended
December 31, 1995 and 1996 and the consolidated balance sheet data as of
December 31, 1995, 1996 and 1997, have been derived from audited consolidated
financial statements of EST that do not appear in this prospectus. The
historical results are not necessarily indicative of the operating results to
be expected in the future.

   EST has been treated as a Subchapter S corporation under the applicable
provisions of the Internal Revenue Code since January 5, 1989. As a Subchapter
S corporation, EST has not been subject to federal and certain state income
taxes. Therefore, the historical net income (loss) and net income (loss) per
share data set forth below does not include provision for federal income taxes.
The pro forma net income (loss) reflects the provision for income taxes that
would have been recorded had EST been a Subchapter C corporation, assuming an
effective tax rate of 40%, 32%, 34%, 40% and 11% for the years ended December
31, 1995, 1996, 1997, 1998 and 1999, respectively. See Notes 2 and 10 to Notes
to Consolidated Financial Statements.

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

   The following discussion and analysis of the financial condition and results
of operations of EST should be read in conjunction with "Selected Consolidated
Financial Data" and EST's consolidated financial statements and notes thereto
appearing elsewhere in this prospectus. This discussion and analysis contains
forward-looking statements that involve risks and uncertainties. You should not
place undue reliance on these forward-looking statements. Our actual results
may differ materially from those anticipated in these forward-looking
statements as a result of certain important factors, including, but not limited
to, those set forth under "Risk Factors" and elsewhere in this prospectus.

Overview

   We design, manufacture, sell and support integrated hardware and software
tools for programming, testing and debugging embedded systems. Embedded systems
are special purpose computers within intelligent industrial and consumer
products such as network switches and routers, cellular base stations, process
control systems, cell phones, printers and anti-lock braking systems. Our
products enable developers to quickly and reliably program and debug the
embedded systems that manufacturers build into their industrial and consumer
products.

   Founded in January 1989 by our current president and chief executive
officer, Peter Dawson, we have experienced consistent annual growth in revenues
and operating profits, except for a loss in the year ended December 31, 1999
attributable to the unusual compensation charge described further below. We
have financed this growth principally from operations and, to a lesser extent,
through periodic short-term bank borrowings. Prior to the offering, EST's
common stock was owned solely by its founder, officers and employees.

   Over the three years ended December 31, 1999, revenues have grown at a
compound annual rate of xx%. We have experienced significant revenue growth
both internationally and domestically as a result of our late 1997 transition
from indirect sales through manufacturing representatives to direct sales
utilizing our own sales personnel; overall growth in industry demand; increased
penetration of major domestic and international accounts; our focus on adding
more functionality and features in an integrated hardware/software development
solution; and comprehensive customer support available from our experienced
development engineers, sales personnel and technical support teams.

   Revenues are recognized when products are shipped against written purchase
orders. Service and extended warranty revenues, which are not significant, are
recognized as earned over the related contract periods. We sell our products
pursuant to purchase orders and do not have long term contracts with customers.
Because we typically ship within 30 days of receipt of an order, we do not have
a significant backlog. The lack of any substantial backlog could contribute to
fluctuations in quarterly operating results.

   In the year ended December 31, 1999, we recorded compensation expense of
$9.4 million related to the fair value of common stock and stock options
awarded to employees and to partial payment of related tax liabilities on
behalf of employees related to the common stock awards. For more information,
please see Note 8 to Notes to the Consolidated Financial Statements.

   Our business could over time be affected materially by competitive changes
in the embedded systems industry, including industry consolidation, decisions
by major industry elements to change their methods of securing tool support for
customer development, improved or restricted access to qualified engineering
employees (for sales and support as well as for research and development), our
present efforts to adapt our tools to support non-Motorola microprocessors, as
well as general industry conditions and trends in individual overseas
economies.

   Costs of revenues as a percentage of sales could be affected by any number
of factors, including availability and prices of key components and
subassemblies. Any gradual improvement in margins as a result

                                       21
<PAGE>

of greater software value and manufacturing efficiencies may well be offset by
higher expenses relating to customer and technical support.

   Our policy is to hire sales, support and development engineers qualified in
the embedded systems field whenever they become available. We are currently
hiring aggressively to staff up for the development and introduction of tools
for new microprocessor families. Hiring in advance of budget could adversely
effect our quarterly results. We intend to continue and accelerate our policy
of maximizing growth in products, features and customer support with the view
of maximizing long-term shareholder value.

   The following table sets forth for the periods indicated the percentage of
total revenue of certain line items included in our statement of operations:

Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

   Revenues. Revenues increased to $28.5 million for the year ended December
31, 1999 from $18.3 million for the year ended December 31, 1998, an increase
of 55.7%. Domestic revenue increased from $12.9 million in the year ended
December 31, 1998 to $19.3 million in the year ended December 31, 1999, an
increase of 48.8%, while foreign revenue increased from $5.3 million in the
year December 31, 1998 to $9.2 million in the year ended December 31, 1999, an
increase of 73.6%. Unit sales for all significant product lines increased. Our
subsidiaries in Japan and the UK contributed strongly to unit sales growth in
overseas revenues for the year as compared with the comparable period in 1998.

   Cost of Revenues. Cost of revenues consists of materials (including
procurement costs of finished boards and subassemblies), manufacturing expenses
(final test, assembly and quality control), and costs associated with our
technical support department. For the year ended December 31, 1999 compared to
the comparable period in 1998, cost of revenues increased to $5.4 million in
1999 from $3.8 million in the 1998 period, but declined as a

                                       22
<PAGE>


percentage of revenues from 20.9% to 18.8%. The decline in cost of revenues as
a percentage of revenues and commensurate increase in gross margins is
attributable to increased features and functionality delivered in our bundled
products, as well as to overall manufacturing efficiencies on higher volumes.

   Selling and Marketing. Selling and marketing expenses increased by 47.2%
from $7.2 million in the year ended December 31, 1998 to $10.6 million in the
year ended December 31, 1999, but decreased as a percentage of revenue from
39.6% to 37.2% during this period. The increase in selling and marketing
expenses was principally due to a growth in sales and marketing personnel,
including salaries, related benefits, commissions, travel and other personnel-
related expenses, from 35 at December 31, 1998 to 70 at December 31, 1999. We
intend to continue to increase the number of sales and marketing personnel and
these associated expenses are likely to continue to increase.

   Research and Development. Research and development expenses increased to
$4.8 million in the year ended December 31, 1999 from $3.1 million in the year
ended December 31, 1998, an increase of 54.8%, and remained constant at 17% as
a percentage of revenue. The increase in research and development expenses
(which includes salaries and related benefits as well as expenses for
development materials and depreciation on computer facilities related to
personnel) was principally due to a growth in research and development
personnel from 23 at December 31, 1998 to 40 at December 31, 1999. Our plans to
adapt our development tools for use with non-Motorola microprocessor
architectures, to add application specific features and to provide software
services to our tools suite, will result in increases in these expenses in the
future.

   General and Administrative. General and administrative expenses increased to
$1.8 million in the year ended December 31, 1999 from $1.0 million in the year
ended December 31, 1998, an increase of 74.5%. The increase in general and
administrative expenses was principally due to a growth in general and
administrative personnel from 7 at December 31, 1998 to 11 at December 31,
1999. We expect to add additional personnel and incur increased infrastructure
costs in support of growth and our status as a publicly-held company.

   Stock-Related Compensation Expense. Results for the year ended December 31,
1999 include a charge of $9.4 million related to the fair value of common stock
and stock options awarded to employees and to partial payment of related tax
liabilities on behalf of employees related to the common stock awards. For more
information, please see Note 8 to Notes to the Consolidated Financial
Statements.

   Interest Income. Interest income increased to $238,000 in the year ended
December 31, 1999 from $42,000 in the year ended December 31, 1998, an increase
of 466.7%. The increase in interest income was largely due to higher average
cash balances.

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

   Revenues. Revenues increased to $18.3 million in the year ended December 31,
1998 from $11.8 million in the year ended December 31, 1997, an increase of
55.1%. Domestic revenue increased from $9.0 million in the year ended December
31, 1997 to $12.9 million in the year ended December 31, 1998, an increase of
43.3%, while foreign revenue increased from $2.8 million in the year ended
December 31, 1997 to $5.3 million in the year ended December 31, 1998, an
increase of 89.3%. All product lines contributed to the revenue growth. The
increase in revenues was due to greater market penetration achieved through an
increase in direct sales personnel as a result of the shift from indirect to
direct selling, both domestically and internationally.

   Cost of Revenues. Cost of revenues increased to $3.8 million for the period
ended December 31, 1998 from $2.9 million for the period ended December 31,
1997, an increase of 33%, but declined as a percentage of revenues to 20.9%
from 24.4%. The corresponding increase in gross margin was principally due to
lower costs associated with direct sales in 1998 compared to sales through
manufacturers' representatives in 1997.

   Selling and Marketing. Selling and marketing expenses increased to $7.2
million for the year ended December 31, 1998 from $4.1 million for the year
ended December 31, 1997, an increase of 78.6%, but

                                       23
<PAGE>

increased as a percentage of revenue from 34.4% to 39.6%. The year-to-year
increase in expenses was due to higher personnel and related costs associated
with converting our distribution channel from reliance on manufacturers'
representatives to a direct sales force. This conversion involved opening
several new sales offices and forming two new subsidiaries, and increasing
selling and marketing personnel from 21 at December 31, 1997 to 29 at December
31, 1998.

   Research and Development. Research and development expenses increased to
$3.1 million in the year ended December 31, 1998 from $2.2 million in the year
ended December 31, 1997, an increase of 43.5%, but decreased as a percentage of
revenue from 18.3% to 16.9%. The increase in research and development expenses
was principally due to increased costs associated with an increase in research
and development personnel from 16 at December 31, 1997 to 23 at December 31,
1998.

   General and Administrative. General and administrative expenses increased to
$1.0 million in the year ended December 31, 1998 from $0.7 million in the year
ended December 31, 1997, an increase of 44.2%, but decreased as a percentage of
revenue from 6.1% to 5.7%. The increase in general and administrative expenses
resulted from higher compensation awarded to key employees in the year ended
December 31, 1998.

   Interest Income. Interest income increased to $42,000 in the year ended
December 31, 1998 from $22,000 in the year ended December 31, 1997, an increase
of 90.9%. The increase in interest income was largely due to higher average
cash balances.

   During the eight quarters ended December 31, 1999, revenues increased
consecutively with the exception of the fourth quarter of 1998, during which we
experienced a slowdown in revenue primarily attributable to new product
introductions and a temporary slowing in industry demand. Cost of revenues
increased to 27.1% of revenues in the quarter ended June 30, 1998 as a result
of book-to-physical inventory charges and cost adjustments to inventory
incurred during that period. Stock-related compensation expense, during the
quarter ended June 30, 1999, attributable to the issuance of common stock to
seven key employees and the grant of stock options to employees in connection
with previously granted common stock rights and stock option rights, distorted
operating expenses and overall results for that period. Although overall
operating expenses, as a percentage of revenues, during the eight quarters
ended December 31, 1999, excluding the stock-related compensation expense in
the quarter ended June 30, 1999, remained steady or declined slightly,
accelerated spending on the development of tools for new microprocessor
families could significantly increase research and development expenses both in
absolute dollars and as a percentage of revenues in future quarters.

Historical and Pro forma (Unaudited) Income Taxes

   EST has been treated as a Subchapter S corporation for federal income tax
purposes since its organization in 1989. As such, EST has not been subject to
federal and certain state income taxes. Therefore, historical provision for
income taxes reflects state and foreign tax provisions only. The increase in
the provision for income taxes over the period from the year ended December 31,
1997 through the year ended December 31, 1999 is due to increased revenues and
profits before taxes in EST's foreign subsidiaries.

   The pro forma provision for income taxes reflects the estimated tax expense
EST would have incurred had it been subject to federal and state income taxes
as a Subchapter C corporation under the Internal Revenue Code. The pro forma
provisions reflect pro forma tax rates of 34%, 40% and 11% for the years ended
December 31, 1997, 1998 and 1999, respectively. The increase in the pro forma
tax rates from the year ended December 31, 1997 to the year ended December 31,
1998 is principally due to higher foreign taxes. The decrease in the pro forma
tax rates from the year ended December 31, 1998 to the year ended December 31,
1999 is principally due to the tax benefit associated with the stock-related
compensation expense offset by an increase in research and development tax
credits which increased the tax benefit generated.

Liquidity and Capital Resources

   Since our inception, we have financed our operations and capital
requirements primarily through cash provided by operations and periodic short-
term borrowing.

   Cash provided by operations was $1.7 million, $2.8 million and $0.5 million
for the fiscal years ended December 31, 1997, 1998 and 1999, respectively. Cash
provided by operations for the year ended December 31, 1999 was primarily
driven by operating profit, excluding compensation expense (see Note 8 to Notes
to Consolidated Financial Statements) as well as increases in accounts payable
and accrued liabilities, offset by increases in accounts receivable.

   Working capital at December 31, 1999 was approximately $3.4 million compared
to approximately $3.8 million at December 31, 1998. The decrease in working
capital from December 31, 1998 to December 31, 1999 was primarily due to
increased expenditures to support EST's growing expense base.

   In December 1999, we borrowed $2.4 million from BankBoston, N.A. to fund in
part the payment of federal and state taxes incurred by us and seven key
employees upon their receipt of stock-related compensation. We intend to repay
this line of credit from the proceeds of this offering. In addition, these
stockholders delivered promissory notes providing for the repayment of
approximately $0.5 million of this amount on or before April 1, 2005, which
notes will be collateralized by their shares of our common stock.

   We believe that the financial resources available to us, including the net
proceeds of the offering, our current working capital, and any future
availability under the working capital portion of our loan agreement, will be
sufficient to finance our planned operations and capital expenditures at least
through 2000. However,

                                       26
<PAGE>

our future liquidity and capital requirements beyond 2000 will depend upon
numerous factors, including the resources required to further develop our
marketing and sales organization domestically and internationally, to expand
manufacturing capacity, and to meet market demand for our products.

Year 2000 Compliance

   The Year 2000 problem stems from the fact that many currently installed
computer systems include software and hardware products that are unable to
distinguish dates after December 31, 1999. As a result, computer software
and/or hardware used by many companies and governmental agencies may need to be
upgraded to comply with Year 2000 requirements or risk system failure or
miscalculations causing disruptions to normal business activities.

   We have defined Year 2000 compliant or Year 2000 readiness as the ability
   to:

  .  Correctly handle date information needed for the December 31, 1999 to
     January 1, 2000 date change;

  .  Function according to the product documentation provided for this date
     change, without changes in operation, assuming correct configuration;

  .  Where appropriate, respond to two-digit date input in a way that
     resolves the ambiguity as to century in a disclosed, defined and
     predetermined manner;

  .  Store and provide output of date information in ways that are
     unambiguous as to century if the date elements in interfaces and data
     storage specify the century; and

  .  Recognize Year 2000 as a leap year.

   State of Readiness. We have made an assessment of the Year 2000 readiness of
our mission critical operating, financial and administrative systems, including
the hardware and software that support our systems. This review included
assessing and validating and, where necessary, remediation, upgrading and
replacing noncompliant systems, hardware or software, as well as evaluating the
need for contingency planning.

   We have completed our Year 2000 compliance efforts and believe that our
products are Year 2000 compliant in all material respects. For all other
mission critical internal information technology systems, we have determined
that all our critical hardware and software is up to date. A small number of
desktop computers and workstations whose operating systems are not Year 2000
compliant was identified, but are not used in ongoing business activities.

   We are also conducting an assessment of our non-information technology
systems. Some aspects of our facilities and manufacturing equipment may include
embedded technology, such as microcontrollers. The Year 2000 problem could
cause a system failure or miscalculation in such facilities or manufacturing
equipment, which could disrupt our operations. Affected areas include voice
mail and phone systems and computer-based test equipment. We believe we have
identified and addressed all material systems for Year 2000 readiness.

   We have experienced no material adverse effect on our products as a result
of the Year 2000 issue, including any problems relating to other vendors or our
target customers. Nevertheless, there can be no assurances that we will not
experience problems resulting from any of the foregoing which could have a
material adverse impact on our business, operating results and financial
condition.

   Costs. Our costs to date associated with assessment, remediation and testing
activities concerning the Year 2000 problem have not been material. Costs
incurred for Year 2000 compliance for our products were included in the regular
costs of research and development. We estimate that we will not incur more than
approximately $5,000 of additional costs in connection with addressing Year
2000 compliance issues.

   Worst Case Scenario. Our reasonably likely worst case Year 2000 scenario
would be that a material third party vendor or supplier, such as a limited or
sole source supplier or a microprocessor manufacturer or operating system
supplier for which we develop tools, or a significant customer, would, as a
result of its own Year 2000 difficulties, fail to successfully remediate Year
2000 problems in hardware, software or equipment which is material to our
business and operations. If this scenario occurred, we may be required to seek
out new vendors and suppliers, which may not be available to us in a timely
basis, if at all. Furthermore, we would be required to certify certain new
limited or sole source suppliers. If we are required to seek out or certify new

                                       27
<PAGE>

vendors or suppliers, it will be costly and divert management attention and our
resources, which could have a material adverse effect on our business and
operating results. If embedded systems manufacturers were to cease using
microprocessors or operating systems which our tools support, our business
would be harmed.

   Contingency Plan. To date, we have no specific contingency plan to address
the effect of Year 2000 compliance failures. If, in the future, it comes to our
attention that certain of our products need modifications or certain of our
third party hardware, software and equipment are not Year 2000 compliant or
certain vendors are not Year 2000 compliant, then we will seek to make the
necessary modifications or substitutions. In such cases, we expect such
modifications or substitutions to be made on a timely basis and we do not
believe that the cost of such modifications or substitutions will have a
material effect on our business, financial condition and results of operations.
There can be no assurance, however, that we will be able to modify our
products, services, systems and equipment or find alternative vendors in a
timely and successful manner to comply with Year 2000 requirements, which could
have a material adverse effect on our business, financial condition and results
of operations.

Conversion to the Euro

   On January 1, 1999, 11 European countries began using the euro as their
single currency, while still continuing to use their own notes and coins for
cash transactions. Bank notes and coins denominated in euros are expected to be
in circulation by 2002, at which time local notes and coins will cease to be
legal tender. We conduct a significant amount of business in these countries
and although our accounting systems permit invoicing in multiple currencies, to
date no customer has requested invoices in Euros. The introduction of the euro
has not resulted in any material adverse impact upon our operations, although
we continue to monitor the effects of the conversion.

Qualitative and Quantitative Disclosures About Market Risk

   We are exposed to financial market risks, including changes in foreign
currency exchange rates and interest rates. Most of our revenue is transacted
in U.S. dollars. However, a significant portion of our international sales and
the expenses and capital spending of our international subsidiaries are
transacted in local currency. As a result, changes in foreign currency exchange
rates or weak economic conditions in foreign markets could affect our financial
results. We do not use derivative instruments to hedge our foreign exchange
risk. Our exposure to market risk for changes in interest rates relates
primarily to our cash and cash equivalents and loan agreement. The majority of
our investments are in short-term instruments and subject to fluctuations in
U.S. interest rates. Due to the short-term nature of our cash equivalents and
note payable, we believe that there is no material risk exposure.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivatives and Hedging Activities," which establishes
accounting and reporting standards for derivative instruments, including
derivative instruments embedded in other contracts, (collectively referred to
as derivatives) and for hedging activities. We will adopt SFAS No. 133 as
required by SFAS 137, "Deferral of the Effective Date of FASB Statement No.
133," in fiscal year 2001. The adoption of SFAS No. 133 is not expected to have
an impact on our financial condition or results of operations.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin 101, "Revenue Recognition in Financial Statements." SAB 101
summarizes the application of generally accepted accounting principles to
revenue recognition in financial statements. EST will apply the accounting and
disclosure requirements of SAB 101 and does not expect its application will
have a material effect on its results of operations.

                                    BUSINESS

Overview

   We design, manufacture, sell and support integrated hardware and software
tools for programming, testing and debugging embedded systems. Our products
enable developers to quickly and reliably program and debug the embedded
systems that are part of the industrial and consumer products they manufacture.
As the complexity and speed of embedded systems increase, we believe that
embedded systems developers will require more efficient solutions to debug
their products and that we are well positioned to offer these solutions.

   A significant portion of our customers are in the communications industry,
including telecommunications, data communications and Internet infrastructure
equipment suppliers. Our largest customers by revenue include Hewlett-Packard,
Lucent Technologies, Motorola, Nortel Networks, Tellabs Wireless and 3Com.

Industry Background

   Embedded systems are the special purpose computers within intelligent
industrial and consumer products such as network switches and routers, cellular
base stations, process control systems, cell phones, printers and anti-lock
braking systems. As with all computers, embedded systems minimally consist of a
microprocessor, memory and software, and the level of complexity of that system
can be enhanced with additional components. Embedded systems differ from
general purpose computers, such as PCs, workstations and mainframes, in that
they are designed to run only the specific set of tasks required for the end
product to operate as intended. Manufacturers use embedded systems to enhance
functionality and performance, reduce cost and size, and improve reliability of
a broad variety of products, ranging from simple systems found in microwave
ovens to complex multiprocessor driven systems controlling the infrastructure
of the Internet.

   According to industry and market research firms, at least 55% of the more
than 265 million microprocessors produced by the semiconductor industry in 1998
were used in embedded systems, while the remainder were used in general purpose
computers such as PCs. We participate in the market for the higher-end 32-bit
and greater embedded microprocessors, which is forecast to grow at a rate of
21%, from 106 million units in 1998 to 228 million units in 2002. Motorola is
the largest supplier of embedded microprocessors, with a market share of 35% in
1997, the latest year for which data is available. The market for embedded
software development tools is part of the overall embedded operating systems
and development tools market, which was approximately $550 million in 1998 and
is forecast to grow 14% annually through 2003.

   The advancement in microprocessors to 32-bit and greater devices has enabled
the development of embedded systems capable of performing more complex tasks
more efficiently. As microprocessor prices have declined and performance has
increased, manufacturers have incorporated more powerful chips into embedded
systems in order to increase the end product's functionality, reduce product
size and cost, and enhance product reliability. As an example, the
implementation of more powerful embedded systems into increasing complex
communications infrastructure equipment has enabled the deployment of greater
network connectivity ranging from small local area networks to the Internet.

   Building a complex embedded system requires significant technical expertise,
time and capital investment. Product manufacturers compete on the basis of the
functionality and quality of their products, and therefore must design and
develop increasingly complex embedded systems that possess greater speed,
performance and reliability. Competitive demands increase pressure to minimize
development costs and time to market. The necessity for product reliability and
interoperability leaves no margin for error or delay in the development cycle.

   Complex embedded systems development projects require sophisticated
development tools. In their search for shorter time to market, increased
functionality, and assured reliability, embedded systems developers demand, and
product manufacturers must invest, in technically sophisticated tools that help
them accomplish these objectives quickly, economically and reliably.

Our Solution

   We design, manufacture, sell and support a comprehensive suite of bundled
high performance, open and scalable embedded systems development tools
consisting of both hardware and software components. We are a worldwide
provider of integrated tools necessary to develop complex embedded systems. Our
tools enable development engineers to program, test and debug embedded systems
quickly, economically and reliably at each stage of the development process. We
believe that our leadership position arises from the following:

   Superior Development Tools. Our tools, which support five different
microprocessor families encompassing more than 50 microprocessor derivatives,
offer the following advantages:

  .  Bundled - We bundle source level software debuggers and other graphical
     utilities with hardware tools to produce a complete solution for early
     stage hardware and firmware development. Traditional hardware tools
     makers generally do not engineer and bundle software development tools
     with hardware tools. Conversely, software tool makers do not develop
     their own hardware connectivity products. Our integrated solution
     enables developers to more effectively visualize the operation of the
     application software on the embedded microprocessor.

  .  Open - We enable developers using our tools to incorporate a broad range
     of real-time operating systems and a wide range of applications. For
     example, during the early stage of hardware and firmware development,
     our tools allow customers to optimize their system design by choosing
     and incorporating the real-time operating system best suited to their
     end product. In the later applications software development phase, the
     customer may choose to maintain hardware connectivity using our tools as
     a platform while integrating tools from other vendors as appropriate.

  .  Graphical - Our software tools provide a rich graphical user-interface,
     which gives developers easy access to multiple in-depth views of
     microprocessor data and development status. For example, simultaneous
     access to microprocessor registers and program data structures increases
     developers' productivity.

  .  Scalable - Our hardware tools are modular and designed to easily allow
     developers to configure and scale their development environments to meet
     their specific needs. For example, developers using our entry level
     products in the early stage of hardware and firmware development can
     subsequently upgrade to our trace analyzer, which provides visibility
     into the real time issues typically associated with later phases of the
     development cycle.

   Microprocessor Knowledge Base. We were one of the first companies in the
industry to develop and market tools for debugging Motorola microprocessors
using its on-chip debug capabilities. We have been able to adapt our tools to
work with over 50 different microprocessors within the Motorola and IBM
families. We have done this through relationships with Motorola and IBM, which
gives us early access to new microprocessor designs prior to commercial
release. We are then able to identify new features and implement them in our
tools for the new microprocessors. We also provide customers with hardware and
software reference designs, which enable them to initiate early development of
their embedded systems.

   Comprehensive Customer Support. We believe customer support and service is a
critical component of our success. Our in-depth knowledge of microprocessor
technology enables us to provide a high level of technical and informational
support to our customers. We deploy a team of 41 sales and support engineers to
assist our customers throughout their development cycles. We effect a major
knowledge transfer to our customers by providing early development kits
containing single board computers and board support packages. We also offer our
customers formal one-day or three-day training sessions on the microprocessor
architectures we support. Because we use embedded systems in our own products
and test and debug them with our own tools, we can anticipate and provide
solutions for the problems our customers are likely to face in the development
cycle.

Our Strategy

   Our goal is to maintain and enhance our position as a technological and
market leader in embedded systems development tools. In order to achieve this
goal, we intend to:

   Extend Our Technological Leadership. The embedded systems industry is
characterized by the introduction of faster microprocessors and more complex
applications software. We have established leadership in development tools by
bundling hardware and software solutions, and we must insure that our products
continue to embody the latest technologies and features. To accomplish this, we
intend to substantially increase our investment in research and development and
expand the number of engineers with embedded systems experience.

   Continue Our Focus On Communications Applications. We believe that the
communications network and Internet infrastructure markets provide us with
major growth opportunities. A significant number of our customers build highly
complex data communications, telecommunications and Internet networking
equipment. These customers require greater visibility into their network
applications during the development stage. We plan to expand our product
offerings to address the specific needs of these developers by leveraging our
existing strengths within the communications market. To do this, we will focus
on making our tools more application specific by adding additional features for
networking and network data acquisition.

   Increase Our Software Product Offerings. Our customers increasingly demand
integrated hardware and software development solutions. We intend to use our
strengths in the hardware bring-up development stage to extend and enhance our
software solutions for embedded systems. We plan to:

  .  extend our graphical user interface products to provide an integrated
     development environment; and

  .  provide systems developers with initialization code and diagnostics that
     can be embedded into a user's end application.

A key aspect of our strategy is to remain operating system independent; that
is, we will build our products to interface with a wide variety of operating
systems.

   Satisfy Customer Demand for Additional Microprocessor Architectures. The
embedded microprocessor market is increasingly competitive, with semiconductor
manufacturers introducing new architectures for embedded applications. We have
adapted our tools to work with more than 50 different microprocessors from
Motorola and IBM. As our customers are exposed to an even wider choice of
microprocessor architectures, we intend to meet their needs by continuing to
adapt our development products for those architectures. Our product design
incorporating field programmable logic devices allows for timely and cost-
effective adaptations to new architectures.

   Strengthen and Develop Strategic Alliances. We believe that our customers
are best served by our having strategic alliances with market leaders. We have
developed significant relationships with both Motorola and Wind River Systems.
These relationships provide us with early access to new microprocessor
technology as well as expanded sales channels. We intend to strengthen these
relationships as well as seek new alliances. Moreover, we may seek additional
technology or distribution channels through selective acquisitions.

Customers

   Our customers develop a wide range of products that incorporate embedded
systems. A significant portion of our customers are in the communications
industry, including telecommunications, data communications and Internet
infrastructure equipment suppliers. In each of 1997 and 1998, no customer
accounted for more than ten percent or more of our revenues and in 1999 Nortel
Networks accounted for ten percent of our revenues. Each of the following

   The following is a representative list of emerging growth companies who have
purchased products from us during fiscal 1999:

     Diamond Lane                              Sycamore Networks
     Castle Networks                           Sunrise Telecom
     Copper Mountain Networks                  Tut Systems

Strategic Relationships

   We have established and will continue to pursue strategic relationships with
significant industry leaders to increase our market penetration and to maintain
our technological leadership. Our principal relationships are with Motorola, a
leading supplier of microprocessors for embedded systems, and with Wind River
Systems, a leading supplier of real time operating systems and software tools
for embedded applications.

   Motorola. Our first products introduced in 1989 were hardware tools which
connected an embedded system developer's workstation to Motorola
microprocessors. Since that time we have enjoyed a close informal relationship
with Motorola that provides us with silicon design documentation and the
related pre-release versions of new microprocessors. This enables us to design
and build tools concurrently with Motorola's microprocessor development cycle
and make these tools available to embedded systems developers at the same time
that Motorola delivers the new microprocessor. These tools, which include
reference designs, help embedded systems designers evaluate the microprocessor
and initiate their development efforts prior to investing in their own hardware
design. Motorola benefits from our relationship because our tools help
customers adopt new microprocessors rapidly into their embedded systems, thus
reducing Motorola's sales cycle.

   Wind River Systems. We have worked closely with Wind River Systems, a
leading supplier of real time operating systems and software tools for embedded
applications. We have jointly designed our tools to provide seamless
integration with Wind River's Tornado(TM) development environment. This
integration provides Wind River customers with critical hardware connectivity
while increasing our target market. In June 1999 we became one of a limited
number of charter members of the Wind River Direct Program. Our membership
allows Wind River's direct sales force to sell our development tools. Recently,
Wind River acquired a development tools company considered by us to be a direct
competitor. We anticipate that Wind River will focus on developing this new
line of business and that our relationship with Wind River is likely to weaken
over time, reducing the volume of sales and sales leads which we might
otherwise have expected.

Products

   We offer bundled hardware and software tools and reference designs for
programming, testing and debugging complex embedded systems throughout their
development cycle. Our products are categorized as follows:

 Microprocessor Connectivity and Debug Run Control Products

   We are a leader in hardware tools that connect a PC or workstation
programming station to a Motorola or IBM embedded microprocessor using on-chip
debug technology. On-chip debug is a set of services that silicon vendors
design into their microprocessors to allow developers to download and test
software running on the embedded system. Substantially all recent 32-bit and
64-bit microprocessors targeted for embedded applications have on-chip debug
capabilities designed into the microprocessor.

 Host Software Tools

   We develop, market and support software development tools which run on PCs
under Windows 9x/NT, as well as workstations under UNIX and Linux. The software
tools provide a graphical user interface designed to control and operate our
hardware connectivity tools and real-time data acquisition systems. The
software tools include C and C++ source-level debuggers. These high-level
language debuggers significantly increase developers' productivity by
correlating microprocessor data and status to the embedded program as
originally coded in the C or C++ programming language.

   We bundle and sell our software tools in combination with our hardware tools
to form an integrated development solution. These tools are:

Reference Designs

   We engineer, market, sell and support reference designs consisting of
microprocessor-based circuit boards, software examples and hardware design
documentation. These components, which constitute our reference designs, create
both a blueprint or roadmap for understanding the particular microprocessor
being programmed and a working environment for programming the microprocessor
prior to incorporation in a customer's product. These reference designs enable
our customers to begin developing systems with a new microprocessor in parallel
with their own hardware development. We also reduce our customers' total
development time by encouraging them to re-use much of the hardware and
software components and intellectual property included in the reference
designs. We offer the following reference designs to our customers:

Sales and Marketing

   Purchase decisions for development tools are generally not centralized.
Typically, project managers decide which development tools to use and their
decisions are based upon the nature of the project and the preferences of the
engineers using the tools. Therefore, our field salespeople may be
simultaneously pursuing multiple sales within the same company. We rely on our
field salespeople and support engineers to make and nurture these contacts with
customer decision makers.

   Our field salespeople and support engineers market our products in North
America, Europe and Japan by direct contact, engineer to engineer, with project
managers and development engineers of existing and prospective customers. We
employ a total of 54 field salespeople and support engineers in North America,
Europe and Japan. We have eight offices in the major markets of North America,
and operate wholly-owned subsidiaries in Canada, France, Germany, Japan, Sweden
and the United Kingdom.

                                       35
<PAGE>

   Our field salespeople and support engineers have on average 10 years
experience in selling to and supporting customers in the embedded systems
industry. We believe that the experience and expertise of our sales and support
staff has been critical in building and sustaining customer relationships.

   We contract with distributors of embedded systems development tools in
China, India, Israel, Italy, Korea and Taiwan for sales and customer support in
these countries. We also utilize direct mail and phone promotions to targeted
prospects and participate in national and international trade shows.

Competition

   The market for development tools used in the embedded systems market is
highly competitive and characterized by rapidly changing technological needs
and capabilities. Competition focuses on a variety of factors, including the
availability of tools that are compatible with the customer's chosen embedded
microprocessor, engineering workstation and other software development
equipment, performance characteristics and features such as high-speed
processing, real-time visibility and control, high-level programming language
and ease-of-use, product reliability, price/performance characteristics,
customer service and worldwide support, and product availability and delivery
time. We believe that the relative importance of each of these factors to a
prospective customer varies for each development project depending upon the
complexity of the embedded system design, the microprocessor to be used, the
project development schedule and the software engineer's budget and experience
level.

   Increased competition could result in price reductions, reduced margins or
loss of market share, any of which could materially adversely affect the
Company's business financial condition and results of operations. If we are
unable to compete successfully against current and future competitors, our
business will be materially adversely affected. We presently compete primarily
against Applied Microsystems, Agilent Technologies and Lauterbach GmbH. In
October, 1999, Wind River Systems acquired Integrated Systems, Inc., which had
earlier in the year acquired a development tools business directly competitive
with ours. Wind River is a major supplier of operating systems which are widely
used by embedded systems makers. We anticipate that Wind River will focus on
the manufacture and sale of programming tools directly competitive with ours
for use in the early stages of hardware and firmware development.

   We anticipate that competition in the embedded systems market is likely to
intensify as competitors consolidate to broaden their product offerings. In
addition, microprocessor manufacturers may acquire or form alliances with
developers of development tools. We believe that much of the competition is
now, and will increasingly be, from companies larger than us and having
substantially greater technical, financial and marketing resources, as well as
larger customer bases and greater name recognition. To compete effectively, we
must continue to differentiate our development tools from those available or
under development by our competitors and we may find it necessary to enter into
alliances with other tool makers, or to acquire other technologies or product
lines, in order to broaden our product offerings.

Intellectual Property

   Our success and ability to compete are dependent on our ability to develop
and maintain the proprietary aspects of our technology and products and operate
without infringing on the proprietary rights of others. We rely primarily on a
combination of trade secret, copyright law and contractual restrictions and to
a lesser extent patent law to protect the proprietary aspects of our products.
These legal protections afford only limited protection for our products. We
presently have one patent application pending in the United States and we
cannot be certain that a patent will be granted based on this or any other
application. We believe that our technological leadership is based on our know-
how, our in-depth expertise in microprocessor technology and our superior
utilization of known core technologies present in the industry.

   For example, we utilize field programmable gate array technology to make our
tools programmable. This means that as we elect to adapt our tools to different
microprocessor architectures, we can do so by re-

                                       36
<PAGE>

programming certain components without having to effect a complete product
redesign. At present, we have re-programmed visionPROBE and visionICE to adapt
to more than 50 different microprocessors within the Motorola PowerPC(TM),
ColdFire(TM) and CPU32 families and the IBM PowerPC(TM) family. We believe that
this feature will also enable us to re-program and adapt our tools for
architectures from other major microprocessor families.

   visionEVENT is our version of high speed logic analysis, or trace, which is
used by programmers to correct extremely complex embedded software bugs. This
technology uses passive pod connectivity, which facilitates connections to the
target microprocessor and enables traces to the microprocessor at higher bus
frequencies than tools using traditional emulation techniques.

   CPMSpy is a recently introduced software utility bundled with visionCLICK.
As visionEVENT captures data from the microprocessor's communications processor
module, CPMSpy uploads the communications data and presents the programmer with
a three pane window showing key information about packet transmission and
behavior.

   Our products are susceptible to reverse engineering; however, we believe
such a process would be difficult, laborious and costly. In addition, we
believe that due to rapid technological change, factors such as the
technological and creative skills of our personnel, new product developments
and enhancements to existing products are more important to establishing and
maintaining a leadership position than the various legal protections afforded
our products.

Research and Development

   We invest significant resources in research and development. In general, we
have invested in new product development and major enhancements to our existing
products through product engineering. A significant portion of our research and
development has focused on:

  .  Broadening the capabilities of our integrated development environment;

  .  Adding new features to address the needs of the communications industry;
     and

  .  Extending our product line to new microprocessors.

   As of January 31, 2000, we had 43 employees engaged in research and
development. We expended approximately $2.1 million, $3.0 million and $4.8
million for the years ended 1997, 1998 and 1999, respectively, on research and
development.

Manufacturing and Facilities

   We conduct final assembly, test, quality assurance, packaging and shipping
of our products at our 28,878 square foot plant in Canton, Massachusetts. Our
purchase managers conduct all parts procurement from the Canton office. Parts
suppliers are selected for their reputation and experience and their output is
tested for quality assurance in Canton. Purchased parts are then collected into
kits and sent for board assembly at any one of several qualified board assembly
companies located in close proximity to our plant. The completed boards are
returned to us for final assembly and testing.

   Typically, our customers place orders when they are about to commence a new
product development cycle. Because we maintain an adequate inventory of
components and are able to assemble products quickly, we can satisfy most
orders within a short period of time after receiving the order. As a result, we
do not have a significant backlog of unfilled orders. We believe that backlog
is neither a significant factor in understanding our business nor a useful
means to predict potential revenue in any particular future period. However,
our inability to predict order volume at any particular time can result in
unexpected increases in our assembly

                                       37
<PAGE>

activity. This requires us to maintain considerable inventory of product
components to avoid delivery delays under such circumstances.

   We moved to our current location in Canton in 1992 and have leased
additional space there as needed from time to time. The present lease expires
on January 1, 2003. We believe that our currently leased facilities are
adequate for operations for the foreseeable future. We presently maintain sales
offices in Dana Point and San Jose, California, Colorado Springs, Colorado,
Westford, Massachusetts, Ambler, Pennsylvania and Addison, Texas in the United
States and Hampshire, England, Vallingby, Sweden, Malsch, Germany, Tokyo,
Japan, Montigny, France and Richmond, Canada. We expect that we will need
additional space if our business expands, and that we will be able to obtain
additional space on an as needed basis on commercially reasonable terms.

Employees

   As of January 31, 2000, 1999, we employed approximately 151 full time
employees world wide as follows: 43 in research and development; 70 in sales
and marketing; 16 in manufacturing; 8 in service and support; and 14 in
administration.

   None of our employees is represented by a union. We believe that our
relationship with our employees is good.

Legal Proceedings

   We are not a party to any material legal proceedings.

Election of Officers and Directors

   The executive officers of EST are elected by the Board of Directors on an
annual basis and serve until their successors are duly elected and qualified.
Our Restated Articles of Organization and Amended and Restated Bylaws provide
that our board of directors will be divided into three classes of directors,
with the classes to be as equal in number as possible. Messrs. Edmunds and
Baggott will serve as Class I directors, whose terms expire at the annual
meeting of stockholders to be held in 2000. Messrs. Neff and Plauger will serve
as Class II directors, whose terms expire at the annual stockholders meeting to
be held in 2001. Messrs. Dawson and Watkins will serve as Class III directors,
whose terms expire at the annual meeting of the stockholders to be held in
2002.

Board Committees

   On December 17, 1999 we established an Audit Committee and a Compensation
Committee. The Audit Committee, which currently consists of Messrs. Neff,
Plauger and Edmunds, reviews our internal accounting procedures and consults
with and reviews the services provided by our independent accountants. The
Compensation Committee, which consists of Messrs. Watkins, Neff and Edmunds,
reviews and determines the compensation and benefits of all our officers and
reviews general policies relating to the compensation and benefits of employees
and administers our Amended and Restated 1999 Stock Option Plan.

Compensation Committee Interlocks and Insider Participation

   Prior to December 1999, we did not have a separate compensation committee or
other board committee performing equivalent functions. These functions were
performed by our board of directors. In December 1999, we established a
compensation committee and appointed Messrs. Watkins, Neff and Edmunds to serve
on the compensation committee.

   The compensation committee evaluates the salaries and incentive compensation
of management and employees of EST and administers our equity incentive plans.
Peter S. Dawson, Chairman of the Board, President and Chief Executive Officer,
participates in discussions and decisions regarding salaries and
incentive compensation for all employees and consultants of EST, except that he
is excluded from all discussions regarding his own salary and incentive
compensation. Other than Mr. Watkins, who serves as our Chief Operating Officer
and Senior Vice President of Sales and Marketing, no member of this committee
was at any time during the past year an officer or employee of EST or any of
its subsidiaries. Other than Mr. Watkins, no member of the compensation
committee owns any capital stock of EST. No interlocking relationships exist
between any member of the compensation committee and any member of any other
company's board of directors or compensation committee. No interlocking
relationship existed between any member of our board of directors and any
member of any other company's board of directors or compensation committee in
1999.

Option Grants

   The table below sets forth grants of stock options granted to each of the
named executive officers during fiscal year 1999. The exercise price per share
of each option was equal to the fair market value of the common stock on the
date of grant as determined by the board of directors. The potential realizable
value is calculated based on the term of the option at its time of grant (10
years). It is calculated assuming that the fair market value of common stock on
the date of grant appreciates at the indicated annual rate compounded annually
for the entire term of the option and that the option is exercised and sold on
the last day of its term for the appreciated stock price.

(1)  The dates of exercisability of the options are determined in accordance
     with their respective vesting schedules. These options vest in five equal
     installments.
(2)  The fair value at the grant date was $2.55 which was determined by the
     Board of Directors based primarily upon the price per share of an arms'
     length offer made by a third party in May 1999 to acquire EST and the
     sales price of a comparable company sold in July 1999.

Amended and Restated 1999 Stock Option Plan

   Our Amended and Restated 1999 Stock Option Plan was adopted by the Board of
Directors on June 15, 1999 and approved by our stockholders on the same day. It
was amended and restated in December 1999. The Plan provides employees,
directors, independent contractors, consultants and advisers an opportunity to
acquire an ownership interest and a shared incentive. During 1999, we granted
options to purchase a total of 2,589,500 shares of common stock to our
employees, of which options for 520,000 shares were granted to our executive
officers. The Plan is administered by the Compensation Committee of the Board
of Directors. As of December 21, 1999, 4,000,000 shares of our common stock
were reserved for issuance under the Plan. The Plan provides for the grant of
incentive stock options and nonqualified stock options. However, eligibility
for the grant of incentive stock options is limited to employees. Options need
not have identical terms with respect to each optionee. Options shall have such
terms and be exercisable in such manner and at such times as the Compensation
Committee may determine. Each option must expire within 10 years from the grant
date. Each option is transferable only by will or the law of descent and
distribution and exercisable only by the optionee during his or her lifetime.

   The Plan remains in effect until June 15, 2009 or earlier if terminated by
the Board of Directors. Any amendment is subject to the approval of
stockholders only to the extent required by applicable laws, regulations or
rules. Rights and obligations under any option may not be materially altered or
impaired without the optionee's consent.

Employment and Non-Competition Agreements

   We have entered into employment agreements with Messrs. Dawson, Watkins,
Lossky and McGillivray, which become effective upon completion of this
offering:

   Mr. Dawson has agreed to serve as President and Chief Executive Officer of
EST, Mr. Watkins has agreed to serve as Chief Operating Officer and Senior Vice
President of Sales and Marketing, Mr. Lossky has agreed to serve as Vice
President of European Sales and Business Development and Mr. McGillivray has
agreed to serve as Vice President of Sales for North America and Asia, each for
a period of three years. Their annual base salary will be $300,000, $240,000,
$150,000 and $170,000 respectively. Each will be entitled to an annual bonus if
certain performance targets established by them and our Compensation Committee
are met.

   Under the agreements, we may terminate either for cause or without cause. If
we terminate any of them without cause we must continue salary payments for the
lesser of 52 weeks or the balance of the employment term. Each may resign on
180-days notice. Their agreements contain non-competition covenants and
provisions limiting the solicitation of our employees for other jobs. These
provisions survive termination of employment for a period of one year.

   On July 1, 1999, we entered into an Employment Agreement with Mr. Baggott
and amended such agreement on December 17, 1999. Mr. Baggott's Employment
Agreement currently provides for an annual salary of $250,000. From January 1,
2000 through December 31, 2000 Mr. Baggott will be paid an annual salary of
$125,000 and be required to work no more than 20 hours per week as Vice
President of Human Resources. After December 31, 2002, Mr. Baggott may continue
to provide services to EST at the same level of compensation, provided,
however, his compensation and related benefits shall be reduced proportionately
if he reduces his responsibilities or time commitment. Mr. Baggott's agreement
contains non-solicitation and non-competition provisions that are intended to
survive termination of his employment.

                              CERTAIN TRANSACTIONS

First Amended and Restated Shareholders' Agreement

   On July 1, 1999 we entered into the First Amended and Restated Founding
Shareholders' Agreement with each of Messrs. Dawson, Watkins and Baggott, each
a director, officer and stockholder of EST. This Agreement will terminate upon
completion of this offering. However, pursuant to the Agreement Messrs. Dawson,
Watkins and Baggott could require EST to purchase annually 10% of their total
common stock or extend to each of them a loan in lieu of such purchase. On July
1, 1999 Mr. Baggott borrowed $550,000 from EST pursuant to a promissory note
secured by a pledge of his EST common stock. Mr. Baggott will pay his
obligations under the promissory note from the proceeds he shall receive from
the sale of his common stock in the offering. On December 17, 1999, each waived
his rights under the Agreement to borrow funds from us, participate in any new
stock issuances and require us to re-purchase any of their shares of common
stock.

Stock Grants

   We granted to employees options to purchase 202,000 shares of our common
stock pursuant to our 1998 Stock Option Plan. Further, in years prior to 1998,
we granted 2,124,000 common stock rights to seven employees pursuant to so-
called "mirror stock" agreements entitling the employees to receive cash upon
the occurrence of certain events, and we issued an option to purchase 659,000
shares of our common stock to Nicolas Lossky which was not pursuant to a plan.
Of these common stock rights, 868,000 were granted to Daniel McGillvray. In
June 1999, we cancelled all outstanding common stock rights and stock options
granted to date. In lieu of cancelled common stock rights and the stock option
not pursuant to a plan, we issued 2,783,000 shares of common stock, which
included 659,000 shares to Mr. Lossky and 868,000 shares to Mr. McGillvray. In
lieu of the remaining cancelled stock options, we granted stock options for
202,000 shares of common stock under the 1999 Stock Option Plan. In connection
with the grant of 2,783,000 shares of common stock, we agreed to pay the
employees' tax liability resulting from the issuance of common stock, provided,
however, that the employees have agreed to repay an amount equal to their
capital gains tax liability. Each has agreed to evidence his or her obligation
with a promissory note collateralized by his or her shares of our common stock.
Payment of these notes will be due no later than April 1, 2005. See Note 8 to
Notes to Consolidated Financial Statements.

Distributions

   We have been treated as a Subchapter S corporation for federal income tax
purposes since our formation in January 1989. As a result, we have never paid
federal, and certain state income taxes. Instead, all of our earnings are
subject to federal, and certain state, income taxation directly at the
stockholder level. In each calendar year, we have distributed enough cash to
our stockholders for them to pay their personal federal and state tax
liabilities to the extent related to our Subchapter S income. Our Subchapter S
corporation status will terminate upon the closing of this offering, at which
time we will become subject to corporate income taxation under Subchapter C of
the Internal Revenue Code. As soon as practicable following the closing of this
offering, we intend to make a distribution to the stockholders of record on the
day prior to the effective date of the registration statement in the amount of
approximately $4.6 million, which is the estimated amount of undistributed
cumulative Subchapter S income from our date of formation through the closing
of this offering, less the sum of amounts previously distributed.

Lease

   Mr. Neff, a director of EST, is the Senior Vice President, Real Estate of
Boston Mutual Insurance Company, the landlord for our principal office in
Canton, Massachusetts. We pay rent in the amount of $52,402 per month to Boston
Mutual Insurance Company.

                       PRINCIPAL AND SELLING STOCKHOLDERS

   The following table sets forth information regarding beneficial ownership of
our common stock as of February 1, 2000, including the selling stockholders, as
adjusted to reflect sale of common stock offered by us in this offering by:

  . each of our directors and the named executive officers;

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

  . each person who beneficially owns more than 5% of the outstanding shares
    of our common stock.

   Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission, and includes voting or investment power
with respect to shares. For purposes of calculating the percentage of shares
beneficially owned, the number of shares of our common stock outstanding as of
February 1, 2000 was 12,894,000 shares. Shares of common stock issuable by EST
to a person named below pursuant to stock options that are exercisable within
60 days after February 1, 2000 are deemed to be beneficially owned and
outstanding for computing the percentage ownership of the person holding the
options. However, these shares are not deemed to be beneficially owned and
outstanding for computing the percentage ownership of any other person.

   Unless otherwise indicated below, to our knowledge, all persons named in the
table have sole voting and investment power with respect to their shares of
common stock, except to the extent authority is shared by spouses under
applicable law. Unless otherwise indicated, the address of each person listed
on the table is c/o Embedded Support Tools Corporation, 120 Royall Street,
Canton, Massachusetts 02021.

                          DESCRIPTION OF CAPITAL STOCK

General

   We are authorized to issue 45,000,000 shares of common stock, $.10 par value
per share, and 5,000,000 shares of preferred stock, $.10 par value per share.

Common Stock

   As of February 1, 2000, there were 12,894,000 shares of common stock
outstanding and held of record by ten stockholders.

   Following the filing of the Restated Articles of Organization all holders of
common stock shall be entitled to one vote for each share held on all matters
submitted to a vote of stockholders and will not have cumulative voting rights.
Accordingly, holders of a majority of the shares of common stock entitled to
vote in any election of directors may elect all of the directors standing for
election. Holders of common stock are entitled to receive ratably such
dividends, if any, as may be declared by the Board of Directors out of funds
legally available therefor, subject to any preferential dividend rights of any
outstanding preferred stock. Upon the liquidation, dissolution or winding up of
EST, the holders of common stock are entitled to receive ratably the net assets
of EST available after the payment of all debts and other liabilities, subject
to the prior rights of any outstanding preferred stock. Holders of the common
stock have no preemptive, subscription, redemption or conversion rights. The
outstanding shares of common stock are, and the shares offered by EST 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 adversely affected by, the rights of the holders of shares of any
series of preferred stock that EST may designate and issue in the future.

Preferred Stock

   The Restated Articles of Organization authorize our Board of Directors,
subject to certain limitations prescribed by law and without further
stockholder approval, from time to time to issue up to an aggregate of
5,000,000 shares of preferred stock, $.10 par value per share, in one or more
series and to fix or alter the designations, preferences and rights, and any
qualifications, limitations or restrictions thereof, of the shares of each such
series, including the number of shares constituting any such series and the
dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption (including sinking fund provisions), redemption price or prices and
liquidation preferences thereof. The issuance of preferred stock may have the
effect of delaying, deferring or preventing a change in control of EST. Upon
the closing of this offering, there will be no shares of preferred stock
outstanding. EST has no present plans to issue any shares of preferred stock.

Massachusetts Law and Certain Provisions of EST's Restated Articles of
Organization and Amended and Restated By-Laws

   Our Amended and Restated By-Laws include a provision excluding EST from the
applicability of Massachusetts General Laws Chapter 110D, entitled "Regulation
of Control Share Acquisitions." In general, this statute provides that any
stockholder of a corporation subject to this statute who acquires 20% or more
of the outstanding voting stock of a corporation may not vote such stock unless
the other stockholders of the corporation so authorize. In addition,
Massachusetts General Laws Chapter 156B, Section 50A generally requires that
publicly-held Massachusetts corporations have a classified board of directors
consisting of three classes as nearly equal in size as possible, unless such
corporation elects to opt out of the statute's coverage. The Amended and
Restated By-Laws contain provisions which give effect to Section 50A.

   The Amended and Restated By-Laws require that nominations for the Board of
Directors made by a stockholder of a planned nomination must be given not less
than 30 and not more than 90 days prior to a scheduled meeting, provided that
if less than 40 days' notice is given of the date of the meeting, a stockholder
will have 10 days within which to give such notice.

                                       46
<PAGE>

   The Amended and Restated By-Laws also require that a stockholder seeking to
have any business conducted at a regularly scheduled meeting of stockholders
generally give notice to EST not less than 120 calendar days prior to the date
EST's proxy statement was released to stockholders in connection with the
previous year's annual meeting. Proposals for meetings of stockholders that are
not regularly scheduled must be received a reasonable time before EST begins to
print its proxy materials. The notice from the stockholder must describe the
proposed business to be brought before the meeting and include information
about the stockholder making the proposal, any beneficial owner on whose behalf
the proposal is made. The By-Laws require EST to call a special stockholders
meeting at the request of stockholders holding at least 40% of the voting
ownership of EST.

   The Restated Articles of Organization provide that the directors and
officers of EST shall be indemnified by EST to the fullest extent authorized by
Massachusetts law, as it now exists or may in the future be amended, against
all expenses and liabilities reasonably incurred in connection with service for
or on behalf of EST. In addition, the Restated Articles of Organization provide
that the directors of EST will not be personally liable for monetary damages to
EST for breaches of their fiduciary duty as directors, unless they have
violated their duty of loyalty to EST or its stockholders, acted in bad faith,
knowingly or intentionally violated the law, including the securities laws,
authorized illegal dividends or redemptions or derived an improper personal
benefit from their action as directors.

   The Restated Articles of Organization provide that any amendment to the
Articles of Organization, the sale, lease or exchange of all or substantially
all of EST's property and assets, or the merger or consolidation of EST into or
with any corporation may be authorized by the approval of the holders of a
majority of the shares of each class of stock entitled to vote thereon, rather
than by two-thirds as otherwise provided by statute, provided that the
transactions have been authorized by a majority of the members of the Board of
Directors and the requirements of any other applicable provisions of the
Articles of Organization have been met.

   The Restated Articles of Organization contain a provision excluding EST from
the applicability of Massachusetts General Laws Chapter 110F, which places
limitations on a Massachusetts corporation's ability to engage in business
combinations with certain stockholders for a period of three years.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is BankBoston, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no public market for our common
stock. The market price of our common stock could drop due to sales of a large
number of shares of our common stock or the perception that such sales could
occur. These factors could also make it more difficult to raise funds through
future offerings of common stock.

   After this offering, 16,994,000 shares of common stock will be outstanding
(17,469,000 shares if the underwriters exercise their over-allotment option
from us in full). Of these shares, the 4,500,000 shares (5,175,000 shares if
the underwriters exercise their over-allotment options in full) sold in this
offering will be freely tradable without restriction under the Securities Act
except for any shares purchased by "affiliates" of the Company as defined in
Rule 144 under the Securities Act. The remaining 12,494,000 shares are
"restricted securities" within the meaning of Rule 144 under the Securities
Act. The restricted securities generally may not be sold unless they are
registered under the Securities Act or are sold pursuant to an exemption from
registration, such as the exemption provided by Rules 144 or 701 under the
Securities Act.

   We, our officers, directors, all of our stockholders and a majority of our
optionholders, including the selling stockholders, have entered into lock-up
agreements pursuant to which we and they have agreed not to offer or sell any
shares of common stock or securities convertible into or exchangeable or
exercisable for shares of common stock for a period of 180 days after the date
of this prospectus without the prior written consent of Prudential Securities
Incorporated, on behalf of the underwriters. Transfers or dispositions can be
made in the case of gifts or estate planning transfers where the donee signs a
lock-up agreement. Prudential Securities Incorporated may, at any time and
without notice, waive any of the terms of these lock-up agreements specified in
the underwriting agreement. Following the lock-up period, these shares will not
be eligible for sale in the public market without registration under the
Securities Act unless such sales meet the conditions and restrictions of Rules
144 and 701 as described below.

   As restrictions on resale end, the market price could drop significantly if
the holders of these restricted shares sell them, or are perceived by the
market as intending to sell them.

</TABLE>

   In general, under Rule 144 as currently in effect, any person (or persons
whose shares are aggregated), including an affiliate, who has beneficially
owned shares for a period of at least one year is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of

   .  1% of the then-outstanding shares of common stock; and

   .  the average weekly trading volume in the common stock during the four
      calendar weeks immediately preceding the date on which the notice of
      such sale on Form 144 is filed with the Securities and Exchange
      Commission.

   Sales under Rule 144 are also subject to certain provisions relating to
notice and manner of sale and the availability of current public information
about EST.

   In addition, a person (or persons whose shares are aggregated) who has not
been an affiliate of EST at any time during the 90 days immediately preceding a
sale, and who has beneficially owned the shares for at least two years, would
be entitled to sell such shares under Rule 144(k) without regard to the volume
limitation and

                                       48
<PAGE>

other conditions described above. Therefore, unless otherwise restricted, Rule
144(k) shares may be sold immediately upon the completion of this offering. The
foregoing summary of Rule 144 is not intended to be a complete description.

   Subject to limitations on the aggregate offering price of a transaction and
other conditions, Rule 701 may be relied upon with respect to the resale of
securities originally purchased from EST by its employees, directors, officers,
consultants or advisors prior to the date the issuer becomes subject to the
reporting requirements of the Exchange Act. To be eligible for resale under
Rule 701, shares must have been issued pursuant to written compensatory benefit
plans or written contracts relating to the compensation of such persons. In
addition, the SEC has indicated that Rule 701 will apply to typical stock
options granted by an issuer before it becomes subject to the reporting
requirements of the Exchange Act, along with the shares acquired upon exercise
of such options (including exercises after the date of the offering).
Securities issued in reliance on Rule 701 are restricted securities and,
subject to the contractual restrictions described above, beginning 90 days
after the date of this prospectus, may be sold by persons other than
affiliates, subject only to the manner of sale provisions of Rule 144, and by
affiliates, under Rule 144 without compliance with its one-year minimum holding
period requirement. The foregoing summary of Rule 701 is not intended to be a
complete description.

   Ninety days following the consummation of this offering, EST intends to file
a registration statement under the Securities Act to register the shares of
common stock available for issuance pursuant to its stock option plans as of
the date of this prospectus. Shares issued pursuant to these plans after the
effective date of such registration statement will be available for sale in the
open market subject to the lock-up period and, for affiliates of EST, subject
to conditions and restrictions of Rule 144.

Securities Incorporated may, at any time and without notice, waive the terms of
these lockup agreements specified in the underwriting agreement.

   Prior to this offering, there has been no public market for our common

and the representatives, is based upon various factors such as our financial

industry we are in and prevailing market conditions.

   Prudential Securities Incorporated, on behalf of the underwriters, may
engage in the following activities in accordance with applicable securities
rules:

    a short position. Prudential Securities Incorporated may elect to reduce
    this short position by exercising some or all of the over-allotment
    option.

  . Stabilizing and short covering: stabilizing bids to purchase the shares
    are permitted if they do not exceed a specified maximum price. After the
    distribution of shares has been completed, short covering purchases in
    the open market may also reduce the short position. These activities may
    cause the price of the shares to be higher than would otherwise exist in
    the open market.

  . Penalty bids permitting the underwriters to reclaim concessions from a
    syndicate member for the shares purchased in the stabilizing or short
    covering transactions that were retained by or released to the syndicate
    member.

   Such activities, which may be commenced and discontinued at any time, may be
effected on the Nasdaq National Market, in the over-the-counter market or
otherwise.

   Each underwriter has represented that it has complied and will comply with
all applicable laws and regulations in connection with the offer, sale or

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Embedded Support Tools Corporation

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
Embedded Support Tools Corporation and its subsidiaries at December 31, 1998
and 1999, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business

   Embedded Support Tools Corporation (the "Company" or "EST") and its
subsidiaries operate in one segment. EST designs, manufactures, sells and
supports hardware and software tools used for development and debugging
embedded systems. Embedded systems are programmable semiconductor chips that
are used in a wide variety of data communications, computer networking,
automotive and consumer electronic applications. EST was incorporated in the
Commonwealth of Massachusetts on January 5, 1989 and is located in Canton,
Massachusetts.

2. Summary of Significant Accounting Policies

 Principles of Consolidation

   The consolidated financial statements include the accounts of Embedded
Support Tools Corporation and its wholly-owned subsidiaries: E.S.T. Corp.
Europe SARL, a French corporation; Embedded Support Tools Corp. Nordic AB, a
Swedish corporation; E.S.T. KK, a Japanese corporation and E.S.T. Corp., UK
Ltd., a United Kingdom corporation. All significant intercompany accounts and
transactions have been eliminated.

 Pro Forma Balance Sheet Presentation (Unaudited)

   The pro forma balance sheet reflects the termination, upon the closing of
EST's initial public offering, of the redemption rights of the existing holders
of common stock resulting in the reclassification of $1,893,000 from redeemable
common stock to common stock and accumulated deficit in the amount of
$1,011,100 and $881,900, respectively. The pro forma balance sheet also gives
effect to the estimated $4,649,000 distribution to shareholders upon the
closing of the initial public offering and reclassification of the remaining
undistributed losses to additional paid-in capital in the amount of $6,753,000.

 Historical and Pro Forma (Unaudited) Net Income (Loss) Per Share

   EST computes basic and diluted earnings per share in accordance with
Statement of Financial Accounting Standards No. 128 ("SFAS 128") "Earnings per
Share." SFAS 128 requires both basic and diluted earnings per share, which is
based on the weighted average number of common shares outstanding, and diluted
earnings per share, which is based on the weighted average number of common
shares outstanding and all dilutive potential common equivalent shares
outstanding. The dilutive effect of options is determined under the treasury
stock method using the average fair value for the period. Common equivalent
shares are included in the per share calculations where the effect of their
inclusion would be dilutive. The stock rights and stock options granted under
stock-based compensation plans in years prior to 1999 have been excluded from
the computation of diluted earnings per share because the employees' right to
the stock was exercisable only upon a future event.

   Historical net income (loss) and net income (loss) per share is not
meaningful as a result of accretion associated with redemption rights on
certain common stock which terminate upon the closing of this offering and
EST's planned conversion from a Subchapter S corporation to a Subchapter C
corporation upon the closing of this offering. For purposes of the pro forma
disclosures, historical net income (loss) has been adjusted to exclude the
accretion and to include the pro forma provision for income taxes calculated
assuming EST was subject to income taxation as a Subchapter C corporation, at a
pro forma tax rate of 34%, 40% and 11% for the years ended December 31, 1997,
1998 and 1999, respectively. In accordance with a regulation of the Securities
and Exchange Commission, pro forma net income (loss) per share for the year
ended December 31, 1999 has been presented to reflect, as of January 1, 1999,
the effect of the assumed issuance of 422,636 shares of

</TABLE>

 Cash and Cash Equivalents

   EST considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents. EST invests its excess
cash primarily in an overnight investment account that invests primarily in
money market accounts, commercial paper and treasury bills. The carrying value
of EST's cash and cash equivalents approximates their fair value. Accordingly,
these investments are subject to minimal credit and market risk.

 Financial Instruments

   The carrying value of EST's financial instruments, which include cash and
cash equivalents, accounts receivable, accounts payable, accrued expenses and
notes payable, approximate their fair values.

 Revenue Recognition

   Revenue from product sales is recognized upon shipment provided that no
uncertainties regarding customer acceptance exist and collection of the related
receivable is probable. Revenue from maintenance services is recognized ratably
over the contract period, generally one year. Revenue from consulting and
training services is recognized when the services are provided.

 Concentration of Credit Risk

   Financial instruments which potentially expose EST to concentrations of
credit risk consist primarily of trade accounts receivable. Management
considers its concentration of credit risk with respect to accounts receivable
to be limited due to its credit evaluation policies, relatively short payment
terms, and geographical dispersion of sales. EST obtains letters of credit for
sales to foreign customers based on management's credit evaluation.

   EST maintains reserves for potential credit losses. Such losses historically
have been minimal and within management's expectations.

 Inventory

   Inventory is stated at the lower of cost or market value, with cost being
determined by the first-in, first-out (FIFO) method.

 Property and Equipment

   Property and equipment are recorded at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets or,
where applicable, over the lease term. The cost of additions and improvements
are capitalized, while expenditures for maintenance and repairs are charged to
expense as incurred. Upon retirement or sale, the cost of the disposed assets
and related accumulated depreciation are removed from the accounts, and any
resulting gain or loss is credited or charged to income.

 Research and Development and Computer Software Development Costs

   Research and development costs are expensed as incurred. Software
development costs are expensed until technological feasibility is established
at which time, and until the product is available for general release to
customers, costs are capitalized. No software development costs were
capitalized during the years ended December 31, 1997, 1998 and 1999, since
costs incurred subsequent to establishment of technological feasibility were
not material.

 Foreign Currency Translation

   The functional currency of EST's foreign subsidiaries is the local currency.
Accordingly, the assets and liabilities of EST's foreign subsidiaries are
translated into U.S. dollars at exchange rates in effect at the balance sheet
date. Income and expense items are translated at average exchange rates for the
period. Foreign currency translation adjustments are included in accumulated
other comprehensive income as a separate component of stockholders' deficit.
Foreign currency transaction gain or losses are recorded in operating expenses
and were not significant for the years ended December 31, 1997, 1998 and 1999.

 Product Warranty Costs

   EST provides three months hardware warranty as part of its product sales.
Estimated future costs for initial product warranties are provided for at the
time of sale.

 Advertising Expense

   EST recognizes advertising expense as incurred. Advertising expense was
approximately $256,000, $310,000 and $669,000 for the years ended December 31,
1997, 1998 and 1999, respectively.

 Accounting for Stock-Based Compensation

   EST accounts for its stock-based awards to employees using the intrinsic
value method as prescribed by Accounting Principles Board ("APB") Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations.
EST has adopted the disclosure only provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation."

 Income Taxes

   Prior to its completed reorganization as a Subchapter C corporation
effective upon completion of the initial public offering, EST has been treated
as a Subchapter S corporation and is not required to pay federal income taxes.
Subchapter S corporation shareholders are required to report their respective
share of EST's taxable income or loss on their individual tax returns and are
personally liable for the related tax.

 Comprehensive Income (Loss)

   Comprehensive income (loss) is defined as the change in equity of a company
during a period from transactions and other events and circumstances excluding
transactions resulting from investments by owners and distributions to owners.
At December 31, 1998 and 1999, accumulated other comprehensive income was
comprised solely of cumulative foreign currency translation adjustments.

 Use of Estimates

   The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Areas particularly subject to estimation include the
allowance for doubtful accounts, inventory reserves and revenue reserves.
Actual results could differ from those estimates.

 Recently Issued Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivatives and Hedging Activities," which establishes
accounting and reporting standards for derivative instruments, including
derivative instruments embedded in other contracts, (collectively referred to
as derivatives) and for hedging activities. EST will adopt SFAS No. 133 as
required by SFAS 137, "Deferral of the Effective Date of FASB Statement No.
133," in fiscal year 2001. The adoption of SFAS No. 133 is not expected to have
an impact on EST's financial condition or results of operations.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin 101, "Revenue Recognition in Financial Statements." SAB 101
summarizes the application of generally accepted accounting principles to
revenue recognition in financial statements. EST will apply the accounting and
disclosure requirements of SAB 101 and does not expect that its application
will have a material effect on its results of operations.

6. Line of Credit

   At December 31, 1999, EST had a $2,500,000 revolving line of credit with
BankBoston, N.A. Borrowings under the line are payable on demand and bear
interest at the Base Rate determined by BankBoston N.A. (8.5% at December 31,
1999). Borrowings are collateralized by all of the assets of EST. Interest is
payable monthly in arrears. Under the terms of the agreement, EST is required
to comply with certain covenants, the most restrictive of which are cash flow
requirements and debt to tangible net worth. EST was in compliance with all
restrictive covenants at December 31, 1999. At December 31, 1999, $2,400,000 of
borrowings were outstanding under the line of credit. See Note 13.

7. Redeemable Common Stock

   On January 1, 1998, EST's stockholders approved an increase in the
authorized shares of common stock, $0.10 par value, to 7,500,000. Also on
January 1, 1998, EST effected a five hundred-for-one stock split of its common
stock in the form of a stock dividend. Accordingly, all share amounts have been
adjusted to give retroactive effect to this stock split. In December 1999, the
Board of Directors approved an increase in the authorized capital of the
Company to 45,000,000 shares of common stock and 5,000,000 shares of preferred
stock. The Board of Directors also approved a two-for-one stock split effected
in the form of a stock dividend. All share and per share amounts in these
consolidated financial statements have been adjusted to give retroactive effect
to this stock split.

   EST had an agreement with certain of its shareholders under which EST had
the right to repurchase all or part of the founders' shares of common stock at
a stated value per share, as defined, upon certain events including death,
termination of employment by EST, permanent disability or retirement. On July
1, 1999, EST executed the First Amended and Restated Founding Shareholders
Agreement ("Amended Shareholders Agreement") which amended and restated the
Shareholders Agreement. Under the Amended Shareholders Agreement, in addition
to EST's right to repurchase the founders' shares, during the period beginning
on July 1, 1999 and ending on the earlier of either an initial public offering
or a change in control, at the election of each individual founder, EST shall
be required to purchase up to 10% per year of the founder's respective shares
of common stock at a redemption price in accordance with a redemption formula,
as defined. Alternately, and in lieu of the right to redeem shares of common
stock, each founder is entitled to obtain loans from EST which are
collateralized by a pledge of shares of common stock. Accordingly, the carrying
value for the common stock has been recorded at its redemption value at
December 31, 1999. On July 1, 1999, a loan totaling $550,000 was issued to a
founder, which is collateralized by a pledge of 220,000 shares of common stock.


8. Stock-Based Compensation

   The 1998 Stock Option Plan ("the 1998 Plan") provided for the grant of
nonqualified stock options to employees. Options granted under the 1998 Plan
were exercisable only upon notification by the Company prior to a change in
control, and expired on the earlier of the day prior to a change in control,
whether or not notification had occurred, and termination of employment.
Options to purchase 202,000 shares of common stock were granted under the 1998
Plan through the year ended December 31, 1998. In addition, prior to 1998, EST
had issued an option, not pursuant to a plan, to an employee to purchase
659,000 shares of common stock and issued common stock rights to employees
pursuant to "mirror stock" agreements under which the employees had rights to
cash or common stock totaling 2,124,000 shares. The employees' rights to common
stock under this option and the "mirror stock" agreements were exercisable only
upon a change in control, registration of the common stock of EST under the
Securities Act of 1933 or liquidation of EST. No compensation expense had been
recorded in the years ended December 31, 1997, 1998 and 1999 with respect to
any stock options or common stock rights granted in years prior to 1999 because
the stock options or common stock rights were contingent and forfeitable upon
the occurrence of certain future events.

   During 1999, EST's Board of Directors approved the 1999 Stock Option Plan
(the "1999 Plan"). The 1999 Plan provides for the granting of incentive and
nonqualified stock options and stock bonus awards to officers, directors,
employees and consultants of EST. The exercise price of stock options granted
under the 1999 Plan is determined by the Board of Directors. The maximum number
of common shares that may be issued pursuant to the 1999 Plan is 4,000,000.
During the year ended December 31, 1999, EST granted 2,462,000 options under
the 1999 Plan to employees, officers and directors. No options have been
granted to consultants. All options granted under the 1999 Plan expire ten
years from the date of grant and generally vest over a five-year period
beginning on the date of hire.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   In June 1999, EST cancelled all outstanding stock options and common stock
rights granted prior to December 31, 1998 and terminated the 1998 Plan and the
"mirror stock" agreements. Also in June 1999, EST granted 2,783,000 shares of
common stock to certain employees, in lieu of the rights to 2,124,000 shares of
common stock under the "mirror stock" agreements and the stock option for
659,000 shares of common stock not pursuant to a plan. EST has a right of first
refusal in any proposed transfer of the shares by the employee until EST
completes an initial public offering. Additionally, EST has a right, but not an
obligation, to repurchase the shares in the event of termination of employment
with EST at the fair value of the common stock as determined by the Board of
Directors. In addition, included in the 2,462,000 stock options granted in
1999, 202,000 stock options were granted in lieu of stock options granted under
the 1998 Plan.

   In connection with the June 1999 grant of 2,783,000 shares of common stock,
at no cost to the grantees, and 1,692,000 stock options, at an exercise price
of $1.73, in June 1999, EST recorded deferred compensation of $8,484,000
representing the difference between the fair value of the common stock of $2.55
at the grant date and the purchase or exercise prices of the common stock and
stock options. During 1999, EST amortized to expense $7,542,000 based on the
vesting provisions. In connection with the issuance of the common stock, EST
agreed to pay a portion of the employees' tax liability resulting from the
issuance of common stock. As a result, an additional charge of $1,895,000 was
also recorded in June 1999. At December 31, 1999, holders of the 2,783,000
shares of common stock issued promissory notes to the Company in the amount of
$472,000, collateralized by the common stock. Payment of these notes will be
due no later than April 1, 2005.

   The Company has adopted the disclosure requirements of SFAS No. 123,
"Accounting for Stock-Based Compensation." The Company continues to recognize
compensation costs using the intrinsic value based method described in
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees." Accordingly, compensation expense recognized was different than
what would have been otherwise recognized under the fair value based method
defined in SFAS No. 123. Had the Company accounted for these plans under SFAS
No. 123, the Company's pro forma net loss to common shareholders and net loss
per share would have been the same for the two years ended December 31, 1997
and 1998 because none of the common stock rights or stock options were
exercisable, and for the year ended December 31, 1999 would have been as
follows:

   <S>                                                                 <C>
   Net loss to common stockholders-as reported (000's)................ ($5,640)
   Net loss to common stockholders-pro forma (000's).................. ($6,929)
   Net loss per common share-basic and diluted as reported............ $ (0.25)
   Net loss per common share-basic and diluted pro forma.............. $ (0.57)
</TABLE>

   Such pro forma disclosures may not be representative of future compensation
cost because options vest over several years and additional grants are expected
to be made.

   For the purpose of providing pro forma disclosures, the fair values of
options granted were estimated using the Black-Scholes option pricing model
with the following weighted average assumptions used for grants in 1999: no
dividend yield; risk free interest rates of 6.33%, 5.49% and 5.87% for the
years ended December 31, 1997, 1998 and 1999; no volatility; and an expected
option term of 6 years.

9. Employee Benefit Plans

   EST maintains a defined contribution plan incorporating features under
section 401(a) of the Internal Revenue Code which covers substantially all
employees. Under the money purchase pension feature of the plan, employer
contributions are determined at a rate of eligible employees' salary. Under the
profit sharing feature of the plan, EST may make annual discretionary
contributions at a rate determined by the Board of Directors. Under the 401(k)
feature of the plan, eligible employees can elect to contribute up to 12% of
their salary limited to a total contribution of $10,000 a year. EST matches
these contributions at a rate of 33% for each dollar contributed by its
employees up to a maximum of 3% of the eligible employee's annual salary.
During the years ended December 31, 1997, 1998 and 1999, EST made contributions
of approximately $300,000, $500,000 and $800,000, respectively.

10. Income Taxes

   The components of the income tax provision are as follows at December 31
(000's):

</TABLE>

   The Company has elected to be taxed as a Subchapter S Corporation for
federal and certain state income tax purposes and, as a result, is not subject
to federal taxation, but is subject to state taxation on income in certain
states. The stockholders are liable for individual federal and certain state
income taxes on their allocated portion of the Company's taxable income. The
foreign taxes primarily represent income taxes of EST's foreign subsidiaries
based upon the income reported in the respective jurisdictions.

   As EST is not subject to federal income taxes, a reconciliation of the
effective tax rate to the federal statutory rate is not meaningful.

11. Commitments and Contingencies

 Commitments

   EST and its subsidiaries lease their facilities and certain office equipment
under operating leases in excess of one year.

   Future minimum lease payments due under noncancellable operating leases are
as follows at December 31, 1999 (000's):

<TABLE>

   Total minimum lease payments......................................... $2,254
                                                                         ======
</TABLE>

   Total rent expense under operating leases was $164,000, $288,000 and
$524,000 for the years ended December 31, 1997, 1998 and 1999, respectively.

 Contingencies

   EST outsources the assembly of its product components to a limited number of
subcontractors. Although there are several available vendors for assembly of
its products, management believes that the nature of its business requires
outsourcing to vendors who have expertise in assembling the components for
EST's products. A change in or loss of one or more of these subcontractors
could cause delays in meeting customer orders, delays in revenue recognition or
the loss of sales which could adversely affect results of operations.

Item 14. Indemnification of Directors And Officers.

   Section 67 of Chapter 156B of the Massachusetts General Laws provides that a
corporation may indemnify its directors and officers to the extent specified in
or authorized by (1) the articles of organization; (2) a by-law adopted by the
stockholders; or (3) a vote adopted by the holders of a majority of the shares
of stock entitled to vote on the election of directors. In all instances, the
extent to which a corporation provides indemnification to its directors and
officers under Section 67 is optional. In its Restated Articles of Organization
(the "Articles of Organization"), the Registrant has elected to commit to
provide indemnification to its directors and officers in specified
circumstances. Generally, Article 6 of the Registrant's Articles of
Organization provides that the Registrant shall indemnify directors and
officers of the Registrant against liabilities and expenses arising out of
legal proceedings brought against them by reason of their status as directors
or officers or by reason of their agreeing to serve, at the request of the
Registrant, as a director or officer with another organization. Under this
provision, a director or officer of the Registrant shall be indemnified by the
Registrant for all costs and expenses (including attorneys' fees), judgments,
liabilities and amounts paid in settlement of such proceedings, even if he is
not successful on the merits, if he acted in good faith in the reasonable
belief that his action was in the best interests of the Registrant. The Board
of Directors may authorize advancing litigation expenses to a director or
officer at his request upon receipt of an undertaking by any such director or
officer to repay such expenses if it is ultimately determined that he is not
entitled to indemnification for such expenses.

   Article 6 of the Registrant's Articles of Organization eliminates the
personal liability of the Registrant's directors to the Registrant or its
stockholders for monetary damages for breach of a director's fiduciary duty,
except to the extent Chapter 156B of the Massachusetts General Laws prohibits
the elimination or limitation of such liability.

   Under Section 9 of the Underwriting Agreement, the Underwriters are
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act of 1933 (the "Securities Act").

 Item 15. Recent Sales of Unregistered Securities.

   Set forth below is information regarding shares of our common stock issued,
and options granted, by the Registrant within the past three years. Further
included is the consideration, if any, received by the Registrant for such
shares and options and information relating to the section of the Securities
Act, or rule of the Securities and Exchange Commission under which exemption
from registration was claimed.

   Certain of the transactions described below involved directors, officers and
5% stockholders of the Registrant. See "Certain Transactions."

   Certain Sales of Securities. Within the past three years, the Registrant has
issued the following securities that were not registered under the Securities
Act.

   The Registrant's Board of Directors approved the 1997 Stock Option Plan and
1998 Stock Option Plan (the "Plans"). The Plans provided for the grant of
nonqualified stock options to employees. Options to purchase an aggregate of
202,000 shares of common stock were granted under the Plans. In addition, prior
to 1998, the Registrant issued an option to Nicolas Lossky to purchase 659,000
shares of common stock, which was exercisable only upon the occurrence of
certain events. In years prior to 1997, Registrant granted common stock rights
under its Mirror Stock Plan that entitled certain of its employees to receive
cash or shares of common stock upon the occurrence of certain events.

   In June 1999, Registrant cancelled all outstanding stock options and common
stock rights granted pursuant to the Plans, as well as the common stock rights
granted to Nicolas Lossky. In exchange, Registrant issued 2,783,000 shares of
common stock to certain employees in lieu of any options to purchase common
stock under previously cancelled options and any common stock rights under the
mirror stock agreements. Additionally, EST has agreed to pay a portion of the
employees' tax liability resulting from the issuance of common stock.

   In June 1999, Registrant's Board of Directors approved the 1999 Stock Option
Plan. The 1999 Plan provides for the granting of incentive and nonqualified
stock options and stock bonus awards to officers, directors, employees and
consultants of EST. In December 1999 the Board of Directors amended and
restated the 1999 Plan to increase the maximum number of shares of common stock
of the Registrant that may be issued pursuant to the 1999 Plan from 2,000,000
to 4,000,000. As of December 17, 1999, Registrant granted 2,589,500 options at
a weighted average exercise price of $3.36 per share.

   No underwriters were involved in the foregoing sales of securities. Such
sales were made in reliance upon exemptions from the registration provisions of
the Securities Act set forth in Sections 3(b) and 4(2) thereof relative to
sales by an issuer not involving any public offering or the rules and
regulations thereunder or, in the case of options to purchase common stock,
Rule 701 of the Securities Act. All of the foregoing securities are deemed
restricted securities for purposes of the Securities Act.

Item 17. Undertakings.

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

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act") may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the provisions
contained in the Registrant's Restated Articles of Organization, the
Underwriting Agreement, the laws of the Commonwealth of Massachusetts, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel that the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

   The undersigned Registrant hereby undertakes that:

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

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

undersigned, thereunto duly authorized, in Canton, Massachusetts on February

     such registration statement, as it may have been amended, has not been
     declared by the Commission to be effective under the Act, an amendment to
     such registration statement, including a form of prospectus, a copy of
     which amendment has been furnished to and approved by the Representatives
     prior to the execution of this Agreement. The Company may also file a
     related registration statement with the Commission pursuant to Rule 462(b)
     under the Act for the purpose of registering certain additional Securities,
     which registration shall be effective upon filing with the Commission. As
     used in this Agreement, the term "Original Registration Statement" means
     the registration statement initially filed relating to the Securities, as
     amended at the time when it was or is declared effective, including all
     financial schedules and exhibits thereto and including any information
     omitted therefrom pursuant to Rule 430A under the Act and included in the
     Prospectus (as hereinafter defined); the term "Rule 462(b) Registration
     Statement" means any registration statement filed with the Commission
     pursuant to Rule 462(b) under the Act (including the Registration Statement
     and any Preliminary Prospectus or Prospectus incorporated therein at the
     time such Registration Statement becomes effective); the term "Registration
     Statement" includes both the Original Registration Statement and any Rule
     462(b) Registration Statement; the term "Preliminary Prospectus" means each
     prospectus subject to completion filed with such registration statement or
     any amendment thereto (including the prospectus subject to completion, if
     any, included in the Registration Statement or any amendment thereto at the
     time it was or is declared effective); the term "Prospectus" means:

               (A) if the Company relies on Rule 434 under the Act, the Term
          Sheet relating to the Securities that is first filed pursuant to Rule
          424(b)(7) under the Act, together with the Preliminary Prospectus
          identified therein that such Term Sheet supplements;

               (B) if the Company does not rely on Rule 434 under the Act, the
          prospectus first filed with the Commission pursuant to Rule 424(b)
          under the Act; or

               (C)  if the Company does not rely on Rule 434 under the Act and
          if no prospectus is required to be filed pursuant to Rule 424(b) under
          the Act, the prospectus included in the Registration Statement;

     and the term "Term Sheet" means any term sheet that satisfies the
     requirements of Rule 434 under the Act.  Any reference herein to the "date"
     of a Prospectus that includes a Term Sheet shall mean the date of such Term
     Sheet.

          (ii) The Commission has not issued any order preventing or suspending
     use of any Preliminary Prospectus.  When any Preliminary Prospectus was
     filed with the Commission it (A) contained all statements required to be
     stated therein in accordance with, and complied in all material respects
     with the requirements of, the Act and the rules and regulations of the
     Commission thereunder and (B) did not include any untrue statement of a

                                       2
<PAGE>

     material fact or omit to state any material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. When the Registration Statement or any amendment
     thereto was or is declared effective, it (A) contained or will contain all
     statements required to be stated therein in accordance with, and complied
     or will comply in all material respects with the requirements of, the Act
     and the rules and regulations of the Commission thereunder and (B) did not
     or will not include any untrue statement of a material fact or omit to
     state any material fact necessary to make the statements therein not
     misleading. When the Prospectus or any Term Sheet that is a part thereof or
     any amendment or supplement to the Prospectus is filed with the Commission
     pursuant to Rule 424(b) (or, if the Prospectus or part thereof or such
     amendment or supplement is not required to be so filed, when the
     Registration Statement or the amendment thereto containing such amendment
     or supplement to the Prospectus was or is declared effective) and on the
     Firm Closing Date and any Option Closing Date (both as hereinafter
     defined), the Prospectus, as amended or supplemented at any such time,
     (A) contained or will contain all statements required to be stated therein
     in accordance with, and complied or will comply in all material respects
     with the requirements of, the Act and the rules and regulations of the
     Commission thereunder and (B) did not or will not include any untrue
     statement of a material fact or omit to state any material fact necessary
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. The foregoing provisions of
     this paragraph (ii) do not apply to statements or omissions made in any
     Preliminary Prospectus, the Registration Statement or any amendment thereto
     or the Prospectus or any amendment or supplement thereto in reliance upon
     and in conformity with written information furnished to the Company by any
     Underwriter through the Representatives specifically for use therein.

          (iii)  If the Company has elected to rely on Rule 462(b) and the
     Rule 462(b) Registration Statement has not been declared effective (A) the
     Company has filed a Rule 462(b) Registration Statement in compliance with
     and that is effective upon filing pursuant to Rule 462(b) and has received
     confirmation of its receipt and (B) the Company has given irrevocable
     instructions for transmission of the applicable filing fee in connection
     with the filing of the Rule 462(b) Registration Statement, in compliance
     with Rule 111 promulgated under the Act or the Commission has received
     payment of such filing fee.

          (iv) The Company and each of its subsidiaries have been duly organized
     and are validly existing as corporations in good standing under the laws of
     their respective jurisdictions of incorporation and are duly qualified to
     transact business as foreign corporations and are in good standing under
     the laws of all other jurisdictions where the ownership or leasing of their
     respective properties or the conduct of their respective businesses
     requires such qualification, except where the failure to be so qualified
     does not amount to a material liability or disability to the Company and
     its subsidiaries, taken as a whole.

          (v) The Company and each of its subsidiaries have full power
     (corporate and other) to own or lease their respective properties and
     conduct their respective businesses as described in the Registration
     Statement and the Prospectus or, if the Prospectus is not in existence, the
     most recent Preliminary Prospectus; and the Company has full power
     (corporate and other) to enter into this Agreement and to carry out all the
     terms and provisions hereof to be carried out by it.

          (vi) The issued shares of capital stock of each of the Company's
     subsidiaries have been duly authorized and validly issued, are fully paid
     and nonassessable and are owned beneficially by the Company free and clear
     of any security interests, liens, encumbrances, equities or claims.

          (vii)  The Company has an authorized, issued and outstanding
     capitalization as set forth in the Prospectus or, if the Prospectus is not
     in existence, the most recent Preliminary Prospectus.  All of the issued
     shares of capital stock of the Company have been duly authorized and
     validly issued and are fully paid and nonassessable.  The Firm Securities
     and the Option Securities have been duly authorized and, at the Firm
     Closing Date or the related Option Closing Date (as the case may be), after
     payment therefor in accordance herewith, will be validly issued, fully paid
     and nonassessable.  No holders of outstanding shares of capital stock of
     the Company are entitled as such to any preemptive or other rights to
     subscribe for any of the Securities, and no holder of securities of the
     Company has any right which has not been fully exercised or waived to
     require the Company to register the offer or sale of any securities owned
     by such holder under the Act in the public offering contemplated by this
     agreement.

          (viii)  The capital stock of the Company conforms to the description
     thereof contained in the Prospectus or, if the Prospectus is not in
     existence, the most recent Preliminary Prospectus.

          (ix) Except as disclosed in the Prospectus (or, if the Prospectus is
     not in existence, the most recent Preliminary Prospectus), there are no
     outstanding (A) securities or obligations of the Company or any of its
     subsidiaries convertible into or exchangeable for any capital stock of the
     Company or any such subsidiary, (B) warrants, rights or options to
     subscribe for or purchase from the Company or any such subsidiary any such
     capital stock or any such convertible or exchangeable securities or
     obligations or (C) obligations of the Company or any such subsidiary to
     issue any shares of capital stock, any such convertible or exchangeable
     securities or obligations, or any such warrants, rights or options.

          (x) The consolidated financial statements and schedules of the Company
     and its consolidated subsidiaries included in the Registration Statement
     and the Prospectus (or, if the Prospectus is not in existence, the most
     recent Preliminary Prospectus) fairly present the financial position of the
     Company and its consolidated

                                       3
<PAGE>

     subsidiaries and the results of operations and changes in financial
     condition as of the dates and periods therein specified. Such financial
     statements and schedules have been prepared in accordance with generally
     accepted accounting principles consistently applied throughout the periods
     involved (except as otherwise noted therein). The selected financial data
     set forth under the caption "Selected Consolidated Financial Data" in the
     Prospectus (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus) fairly present, on the basis stated in the
     Prospectus (or such Preliminary Prospectus), the information included
     therein.

          (xi) PricewaterhouseCoopers LLC, who have certified certain financial
     statements of the Company and its consolidated subsidiaries and delivered
     their report with respect to the audited consolidated financial statements
     and schedules included in the Registration Statement and the Prospectus
     (or, if the Prospectus is not in existence, the most recent Preliminary
     Prospectus), are independent public accountants as required by the Act and
     the applicable rules and regulations thereunder.

          (xii)  The execution and delivery of this Agreement have been duly
     authorized by the Company and this Agreement has been duly executed and
     delivered by the Company and is the valid and binding agreement of the
     Company, enforceable against the Company in accordance with its terms.

          (xiii)  No legal or governmental proceedings are pending to which the
     Company or any of its subsidiaries is a party or to which the property of
     the Company or any of its subsidiaries is subject that are required to be
     described in the Registration Statement or the Prospectus (or, if the
     Prospectus is not in existence, the most recent Preliminary Prospectus) and
     are not described therein, and no such proceedings have been threatened
     against the Company or any of its subsidiaries or with respect to any of
     their respective properties; and no contract or other document is required
     to be described in the Registration Statement or the Prospectus or to be
     filed as an exhibit to the Registration Statement that is not described
     therein (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus) or filed as required.

          (xiv)  The issuance, offering and sale of the Securities to the
     Underwriters by the Company pursuant to this Agreement, the compliance by
     the Company with the other provisions of this Agreement and the
     consummation of the other transactions herein contemplated do not
     (A) require the consent, approval, authorization, registration or
     qualification of or with any governmental authority, except such as have
     been obtained, such as may be required under state securities or blue sky
     laws and, if the registration statement filed with respect to the
     Securities (as amended) is not effective under the Act as of the time of
     execution hereof, such as may be required (and shall be obtained as
     provided in this Agreement) under the Act, or (B) conflict with or result
     in a breach or violation of any of the terms and provisions of, or
     constitute a default under, any indenture, mortgage, deed of trust, lease
     or other agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which the Company or any of its subsidiaries
     or any of their respective properties are bound, or the charter documents
     or by-laws of the Company or any of its subsidiaries, or any statute or any
     judgment, decree, order, rule or regulation of any court or other
     governmental authority or any arbitrator applicable to the Company or any
     of its subsidiaries.

          (xv) Subsequent to the respective dates as of which information is
     given in the Registration Statement and the Prospectus (or, if the
     Prospectus is not in existence, the most recent Preliminary Prospectus)
     neither the Company nor any of its subsidiaries has sustained any material
     loss or interference with their respective businesses or properties from
     fire, flood, hurricane, accident or other calamity, whether or not covered
     by insurance, or from any labor dispute or any legal or governmental
     proceeding and there has not been any material adverse change, or any
     development involving a prospective material adverse change, in the
     condition (financial or otherwise), management, business prospects, net
     worth, or results of the operations of the Company or any of its
     subsidiaries, except in each case as described in or contemplated by the
     Prospectus or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus.

          (xvi)  The Company has not, directly or indirectly, (A) taken any

     might reasonably be expected to constitute, the stabilization or
     manipulation of the price of any security of the Company to facilitate the
     sale or resale of the Securities, or (B) since the filing of the
     Registration Statement (1) sold, bid for, purchased or paid anyone any
     compensation for soliciting purchases of, the Securities, or (2) paid or
     agreed to pay to any person any compensation for soliciting

                                       4

     another to purchase any other securities of the Company (except for the
     sale of Securities by the Selling Stockholders under this Agreement).

          (xvii)  The Company has not distributed and, prior to the later of
     (A) the Closing Date and (B) the completion of the distribution of the

     Statement or any amendment thereto, any Preliminary Prospectus or the
     Prospectus or any amendment or supplement thereto, or other materials, if
     any permitted by the Act.

     the most recent Preliminary Prospectus).

          (xix)  The Company and each of its subsidiaries have good and
     marketable title in fee simple to all items of real property and marketable
     title to all personal property owned by each of them, in each case free and
     clear of any security interests, liens, encumbrances, equities, claims and
     other defects, except such as do not materially and adversely affect the
     value of such property and do not interfere with the use made or proposed
     to be made of such property by the Company or such subsidiary, and any real
     property and buildings held under lease by the Company or any such
     subsidiary are held under valid, subsisting and enforceable leases, with
     such exceptions as are not material and do not interfere with the use made
     or proposed to be made of such property and buildings by the Company or
     such subsidiary, in each case except as described in or contemplated by the
     Prospectus (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus).

     their respective businesses, and neither the Company nor any such
     subsidiary has received any notice of infringement of or conflict with
     asserted rights of any third party with respect to any of the foregoing

     results of operations of the Company and its subsidiaries, except as
     described in or contemplated by the Prospectus (or, if the Prospectus is

     which they are engaged; neither the Company nor any such subsidiary has
     been refused any insurance coverage sought or applied for; and neither the
     Company nor any such subsidiary has any reason to believe that it will not
     be able to renew its existing insurance coverage as and when such coverage

     subsidiaries, except as described in or contemplated by the Prospectus (or,
     if the Prospectus is not in existence, the most recent Preliminary

     any notice of proceedings relating to the revocation or modification of any
     such certificate, authorization or permit which, singly or in the

     would result in a material adverse change in the condition (financial or
     otherwise), business prospects, net worth or results of operations of the
     Company and its subsidiaries, except as described in or contemplated by the
     Prospectus (or, if the Prospectus is not in existence, the most recent
     Preliminary Prospectus).

          (xxv)  The Company will conduct its operations in a manner that will
     not subject it to registration as an investment company under the
     Investment Company Act of 1940, as amended, and this transaction will not
     cause the Company to become an investment company subject to registration
     under such Act.

          (xxvi)  The Company has filed all foreign, federal, state and local
     tax returns that are required to be filed or has requested extensions

     all taxes required to be paid by it and any other assessment, fine or
     penalty levied against it, to the extent that any of the foregoing is due

     required of them under applicable federal and state occupational safety and
     health and environmental laws and regulations to conduct their respective
     businesses, and the Company and each such subsidiary is in compliance with
     all terms and conditions of any such permit, license or approval, except
     any such violation of law or regulation, failure to receive required
     permits, licenses or other approvals or failure to comply with the terms
     and conditions of such permits, licenses or approvals which would not,
     singly or in the aggregate, result in a material adverse change in the
     condition (financial or otherwise), business prospects, net worth or
     results of operations of the Company and its subsidiaries, except as
     described in or contemplated by the Prospectus (or, if the Prospectus is
     not in existence, the most recent Preliminary Prospectus).

          (xxviii)  Each certificate signed by any officer of the Company and
     delivered to the Representatives or counsel for the Underwriters shall be

     covered thereby.

          (xxix)  Except for the shares of capital stock of each of the
     subsidiaries owned by the Company and such subsidiaries, neither the
     Company nor any such subsidiary owns any shares of stock or any other
     equity securities of any corporation or has any equity interest in any
     firm, partnership, association or other entity, except as described in or
     contemplated by the Prospectus (or, if the Prospectus is not in existence,
     the most recent Preliminary Prospectus).

          (xxx)  There are no holders of securities of the Company, who, by
     reason of the filing of the Registration Statement, have the right (and
     have not waived such right) to request the Company to register under the
     Act, or to include in the Registration Statement, securities held by them.

          (xxxi)  The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (A) transactions are executed in accordance with

     conformity with generally accepted accounting principles and to maintain
     asset accountability, (C) access to assets is permitted only in accordance
     with management's general or specific authorization, and (D) the recorded
     accountability for assets is compared with the existing assets at
     reasonable intervals and appropriate action is taken with respect to any
     differences.

          (xxxii)  No default exists, and no event has occurred which, with
     notice or lapse of time or both, would constitute a default in the due
     performance and observance of any term, covenant or condition of any
     indenture, mortgage, deed of trust, lease or other agreement or instrument
     to which the Company or any of its subsidiaries is a party or by which the
     Company or any of its subsidiaries or any of their respective properties is
     bound or may be affected in any material adverse respect with regard to
     property, business or operations of the Company and its subsidiaries.

     (b) Representations and Warranties of the Selling Stockholders.  Each of

     and delivered by such Selling Stockholder.

          (ii)  Such Selling Stockholder has duly executed and delivered a power

     executed and delivered by such Selling Stockholder and, assuming due
     authorization, execution and delivery by the Custodian, are the legal,
     valid, binding and enforceable instruments of such Selling Stockholder.

     to carry out the terms of this Agreement, are to that extent irrevocable

     terminated, except as provided in this Agreement or the Custody Agreement,

     incapacity of such Selling Stockholder, in the case of a trust or estate by
     the death of the trustee or trustees or the executor or executors or the
     termination of such trust or estate, or by the occurrence of any other
     event.  If any such Selling Stockholder, trustee or executor should die or
     become incapacitated or any such trust should be terminated, or if any
     other event should occur, before the delivery of such Securities hereunder,
     the certificates for such Securities deposited with the Custodian shall be
     delivered by the Custodian in accordance with the respective terms and
     conditions of this Agreement as if such death, incapacity or other event
     had not occurred, regardless of whether or not the Custodian or the
     Attorney in Fact shall have received notice thereof.

          (iii)   Such Selling Stockholder is the lawful owner of the Securities
     to be sold by such Selling Stockholder hereunder and upon sale and delivery
     of, and payment for, such Securities, as provided herein, such Selling
     Stockholder will convey good and marketable title to such Securities, free
     and clear of any security interests, liens, encumbrances, equities, claims
     or other defects.

          (iv)  Such Selling Stockholder has not, directly or indirectly,
     (A) taken any action designed to cause or result in, or that has
     constituted or which might reasonably be expected to constitute, the
     stabilization or manipulation of the price of any security of the Company
     to facilitate the sale or resale of the Securities or (B) since the filing
     of the Registration Statement (1) sold, bid for, purchased, or paid anyone
     any compensation for soliciting purchases of, the Securities or (2) paid or
     agreed to pay to any person any compensation for soliciting another to
     purchase any other securities of the Company (except for the sale of
     Securities by the Selling Stockholders under this Agreement.

          (v)  Such Selling Stockholder has reviewed the Prospectus (or, if the
     Prospectus is not in existence, the most recent Preliminary Prospectus) and
     the Registration Statement, and the information regarding such Selling
     Stockholder set forth therein under the caption "Principal and Selling
     Stockholders" is complete and accurate.

          (vi)  The sale by such Selling Stockholder of Securities pursuant
     hereto is not prompted by any adverse information concerning the Company
     that is not set forth in the Registration Statement or the Prospectus (or,
     if the Prospectus is not in existence, the most recent Preliminary
     Prospectus).

          (vii)   The sale of the Securities to the Underwriters by such Selling
     Stockholder pursuant to this Agreement, the compliance by such Selling
     Stockholder with the other provisions of this Agreement and the Custody
     Agreement and the consummation of the other transactions herein
     contemplated do not require the consent, approval, authorization,
     registration or qualification of or with any governmental authority, except
     such as have been obtained, such as may be required under state securities
     or blue sky laws and, if the registration statement filed with respect to
     the Securities (as amended) is not effective under the Act as of the time
     of execution hereof, such as may be required (and shall be obtained as
     provided in this Agreement) under the Act.

     3.   Purchase, Sale and Delivery of the Securities.  (a) On the basis of
          ---------------------------------------------
the representations, warranties, agreements and covenants herein contained, and
subject to the terms and conditions herein set forth, the Company agrees to
issue and sell, and John T.W. Baggott, the Selling Stockholder, agrees to sell,
to each of the Underwriters, and each of the Underwriters, severally and not
jointly, agrees to purchase from the Company and John T.W. Baggott, at a
purchase price of $[________] per share, the number of Firm Securities set forth
opposite the name of such Underwriter in Schedule I hereto.  One or more
certificates in definitive form for the Firm Securities that the several
Underwriters have agreed to purchase hereunder, and in such denomination or
denominations and registered in such name or names as the Representatives
request upon notice to the Company at least 48 hours prior to the Firm Closing
Date, shall be delivered by or on behalf of the Company and John T.W. Baggott to
the Representatives for the respective accounts of the Underwriters, against
payment by or on behalf of the Underwriters of the purchase price therefor by
wire transfer in same-day funds (the "Wired Funds") to the account of the
Company.  Such delivery of and payment for the Firm Securities shall be made at
the offices of Testa, Hurwitz & Thibeault, LLP at 9:30 A.M., New York City time,
on __________, 2000, or at such other place, time or date as the Representatives
and the Company may agree upon or as the Representatives may determine pursuant
to Section 9 hereof, such time and date of delivery against payment being herein
referred to as the "Firm Closing Date."  The Company will make such certificate
or certificates for the Firm Securities available for checking and packaging by
the Representatives at the offices in New York, New York of the Company's
transfer agent or registrar or of Prudential Securities Incorporated at least 24
hours prior to the Firm Closing Date.

     (b) For the purpose of covering any over-allotments in connection with the
distribution and sale of the Firm Securities as contemplated by the Prospectus,
the Company and another Selling Stockholder, James E. Watkins,  hereby grant to
the several Underwriters an option to purchase, severally and not jointly, the
Option Securities.  The purchase price to be paid for any Option Securities
shall be the same price per share as the price per share for the Firm Securities
set forth above in paragraph (a) of this Section 3, plus, if the purchase and
sale of any Option Securities takes place after the Firm Closing Date and after
the Firm Securities are trading "ex-dividend," an amount equal to the dividends
payable on such Option Securities.  The option granted hereby may be exercised
as to all or any part of the Option Securities from time to time within thirty
days after the date of the Prospectus (or, if such 30th day shall be a Saturday
or Sunday or a holiday, on the next business day thereafter when the New York
Stock Exchange is open for trading).  The Underwriters shall not be under any
obligation to purchase any of the Option Securities prior to the exercise of
such option.  The Representatives may from time to time exercise the option
granted hereby by giving notice in writing or by telephone (confirmed in
writing) to the Company and James E. Watkins setting forth the aggregate

                                       8
<PAGE>

number of Option Securities as to which the several Underwriters are then
exercising the option and the date and time for delivery of and payment for such
Option Securities. Any such date of delivery shall be determined by the
Representatives but shall not be earlier than two business days or later than
five business days after such exercise of the option and, in any event, shall
not be earlier than the Firm Closing Date. The time and date set forth in such
notice, or such other time on such other date as the Representatives and Company
may agree upon or as the Representatives may determine pursuant to Section 9
hereof, is herein called the "Option Closing Date" with respect to such Option
Securities. Upon exercise of the option as provided herein, the Company and
James E. Watkins shall become obligated to sell to each of the several
Underwriters, and, subject to the terms and conditions herein set forth, each of
the Underwriters (severally and not jointly) shall become obligated to purchase
from the Company and James E. Watkins, the same percentage of the total number
of the Option Securities as to which the several Underwriters are then
exercising the option as such Underwriter is obligated to purchase of the
aggregate number of Firm Securities, as adjusted by the Representatives in such
manner as they deem advisable to avoid fractional shares. If the option is
exercised as to all or any portion of the Option Securities, one or more
certificates in definitive form for such Option Securities, and payment
therefor, shall be delivered on the related Option Closing Date in the manner,
and upon the terms and conditions, set forth in paragraph (a) of this Section 3,
except that reference therein to the Firm Securities and the Firm Closing Date
shall be deemed, for purposes of this paragraph (b), to refer to such Option
Securities and Option Closing Date, respectively.

     (c) The Company and the Selling Stockholders hereby acknowledge that the
wire transfer by or on behalf of the Underwriters of the purchase price for any
Securities does not constitute closing of a purchase and sale of the Securities.
Only execution and delivery of a receipt for the Securities by the Underwriters
indicates completion of the closing of a purchase of the Securities from the
Company and the Selling Stockholders.  Furthermore, in the event that the
Underwriters wire funds to the Company and the Selling Stockholders prior to the
completion of the closing of a purchase of Securities, the Company and the
Selling Stockholders hereby acknowledge that until the Underwriters execute and
deliver a receipt for the Securities, by facsimile or otherwise, the Company
will not be entitled to the Wired Funds and shall return the Wired Funds to the
Underwriters as soon as practicable (by wire transfer of same-day funds) upon
demand.  In the event that the closing of a purchase of Securities is not
completed and the Wired Funds are not returned by the Company and the Selling
Stockholders to the Underwriters on the same day the Wired Funds were received
by same, the Company and the Selling Stockholders agree to pay to the
Underwriters in respect of each day the Wired Funds are not returned by it, in
same-day funds, interest on the amount of such Wired Funds in an amount
representing the Underwriters' cost of financing as reasonably determined by
Prudential Securities Incorporated.

     (d)  It is understood that any of you, individually and not as one of the
Representatives, may (but shall not be obligated to) make payment on behalf of
any Underwriter or Underwriters for any of the Securities to be purchased by
such Underwriter or Underwriters.  No such payment shall relieve such
Underwriter or Underwriters from any of its or their obligations hereunder.

     4.   Offering by the Underwriters.  Upon your authorization of the release
          ----------------------------
of the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.

     5.   (a) Covenants of the Company, the Selling Stockholders and Peter S.
          ----------------------------
Dawson. The Company, the Selling Stockholders and Peter S. Dawson covenant and
agree with each of the Underwriters that:

          (i)  The Company will cause the Registration Statement, if not
     effective at the time of execution of this Agreement, and any amendments
     thereto to become effective as promptly as possible.  If required, the
     Company will file the Prospectus or any Term Sheet that constitutes a part
     thereof and any amendment or supplement thereto with the Commission in the
     manner and within the time period required by Rules 434 and 424(b) under
     the Act.  During any time when a prospectus relating to the Securities is
     required to be delivered under the Act, the Company (A) will comply with
     all requirements imposed upon it by the Act and the rules and regulations
     of the Commission thereunder to the extent necessary to permit the
     continuance of sales of or dealings in the Securities in accordance with
     the provisions hereof and of the Prospectus, as then amended or
     supplemented, and (B) will not file with the Commission the prospectus,
     Term Sheet or the amendment referred to in the second sentence of Section
     2(a)(i) hereof, any amendment or supplement to such Prospectus, Term Sheet
     or any amendment to the Registration Statement or any Rule 462(b)
     Registration Statement of which the Representatives previously have been
     advised and furnished with a copy for a reasonable period of time prior to
     the proposed filing and as to which filing the Representatives shall not
     have given their consent.  The Company will prepare and file with the
     Commission, in accordance with the rules and regulations of the Commission,

                                       9
<PAGE>

     promptly upon request by the Representatives or counsel for the
     Underwriters, any amendments to the Registration Statement or amendments or
     supplements to the Prospectus that may be necessary or advisable in
     connection with the distribution of the Securities by the several
     Underwriters, and will cause any such amendment to the Registration
     Statement to be declared effective by the Commission as promptly as
     possible.  The Company will advise the Representatives, promptly after
     receiving notice thereof, of the time when the Registration Statement or
     any amendment thereto has been filed or declared effective or the
     Prospectus or any amendment or supplement thereto has been filed and will
     provide evidence satisfactory to the Representatives of each such filing or
     effectiveness.

          (ii) The Company will advise the Representatives, promptly after
     receiving notice or obtaining knowledge thereof, of (A) the issuance by the
     Commission of any stop order suspending the effectiveness of the Original
     Registration Statement or any Rule 462(b) Registration Statement or any
     amendment thereto or any order preventing or suspending the use of any
     Preliminary Prospectus or the Prospectus or any amendment or supplement
     thereto, (B) the suspension of the qualification of the Securities for
     offering or sale in any jurisdiction, (C) the institution, threatening or
     contemplation of any proceeding for any such purpose, or (D) any request
     made by the Commission for amending the Original Registration Statement or
     any Rule 462(b) Registration Statement, for amending or supplementing the
     Prospectus or for additional information.  The Company will use its best
     efforts to prevent the issuance of any such stop order and, if any such
     stop order is issued, to obtain the withdrawal thereof as promptly as
     possible.

          (iii)  The Company will arrange for the qualification of the
     Securities for offering and sale under the securities or blue sky laws of
     such jurisdictions as the Representatives may designate and will continue
     such qualifications in effect for as long as may be necessary to complete
     the distribution of the Securities, provided, however, that in connection
                                         --------  -------
     therewith the Company shall not be required to qualify as a foreign
     corporation or to execute a general consent to service of process in any
     jurisdiction.

          (iv) If, at any time prior to the later of (A) the final date when a
     prospectus relating to the Securities is required to be delivered under the
     Act or (B) the Option Closing Date, any event occurs as a result of which
     the Prospectus, as then amended or supplemented, would include any untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading, or if for any other reason it
     is necessary at any time to amend or supplement the Prospectus to comply
     with the Act or the rules or regulations of the Commission thereunder, the
     Company will promptly notify the Representatives thereof and, subject to
     Section 5(a)(i) hereof, will prepare and file with the Commission, at the
     Company's expense, an amendment to the Registration Statement or an
     amendment or supplement to the Prospectus that corrects such statement or
     omission or effects such compliance.

          (v) The Company will, without charge, provide (A) to the
     Representatives and to counsel for the Underwriters a conformed copy of the
     registration statement originally filed with respect to the Securities and
     each amendment thereto (in each case including exhibits thereto) or any
     Rule 462(b) Registration Statement, certified by the Clerk or an Assistant
     Clerk of the Company to be true and complete copies thereof as filed with
     the Commission by electronic transmission, (B) to each other Underwriter, a
     conformed copy of such registration statement or any Rule 462(b)
     Registration Statement and each amendment thereto (in each case without
     exhibits thereto) and (C) so long as a prospectus relating to the
     Securities is required to be delivered under the Act, as many copies of
     each Preliminary Prospectus or the Prospectus or any amendment or
     supplement thereto as the Representatives may reasonably request; without
     limiting the application of clause (C) of this sentence, the Company, not
     later than (1) 6:00 P.M., New York City time, on the date of determination
     of the public offering price, if such determination occurred at or prior to
     10:00 A.M., New York City time, on such date, or (2) 2:00 P.M., New York
     City time, on the business day following the date of determination of the
     public offering price, if such determination occurred after 10:00 A.M.,
     New York City time, on such date, will deliver to the Underwriters, without
     charge, as many copies of the Prospectus and any amendment or supplement
     thereto as the Representatives may reasonably request for purposes of
     confirming orders that are expected to settle on the Firm Closing Date.

          (vi) The Company, as soon as practicable, will make generally
     available to its stock holders and to the Representatives a consolidated
     earnings statement of the Company and its subsidiaries that satisfies the

     exchangeable or exercisable for, shares of Common Stock for a period of
     180 days after the date hereof, except pursuant to this Agreement and
     except for issuances pursuant to the exercise of employee stock options
     granted or to be granted under the Company's Amended and Restated 1999
     Stock Option Plan, as such plan exists on the date hereof, provided that
     prior to any such issuance of securities under such plan, the
     Representatives shall have received a lock-up agreement (as described in
     Section 7(f) hereto) from each person to be issued such securities.

          (ix) The Company and Peter S. Dawson will not, directly or indirectly,
     (A) take any action designed to cause or to result in, or that has
     constituted or which might reasonably be expected to constitute, the
     stabilization or manipulation of the price of any security of the Company
     to facilitate the sale or resale of the Securities or (B) (1) sell, bid
     for, purchase, or pay anyone any compensation for soliciting purchases of
     the Securities or (2) pay or agree to pay to any person any compensation

     any rumor, publication or event relating to or affecting the Company shall
     occur as a result of which in your opinion the market price of the Common
     Stock has been or is likely to be materially affected (regardless of
     whether such rumor, publication or event necessitates a supplement to or
     amendment of the Prospectus), the Company will, after notice from you
     advising the Company to the effect set forth above, forthwith prepare,
     consult with you concerning the substance of and disseminate a press
     release or other public statement, reasonably satisfactory to you,
     responding to or commenting on such rumor, publication or event.

     securities under such plan, the Representatives shall have received a lock-

     issued such securities.

          (ii)  Such Selling Stockholder will not, directly or indirectly,

     Underwriters' compliance with the reporting and withholding provisions of
     the Internal Revenue Code of 1986, as amended, with respect to the
     transactions herein contemplated, agree to deliver to you prior to or on
     the Firm Closing Date, as hereinafter defined, a properly completed and
     executed United States Treasury Department Form W-8 or W-9 (or other
     applicable form of statement specified by Treasury Department regulations
     in lieu thereof).

     6.   Expenses.  The Company will pay all costs and expenses incident to the
          --------
performance of its obligations under this Agreement, whether or not the
transactions contemplated herein are consummated or this Agreement is terminated
pursuant to Section 11 hereof, including all costs and expenses incident to

because this Agreement is terminated pursuant to Section 11 hereof, or because
of any failure, refusal or inability on the part of the Company to perform all
obligations and satisfy all conditions on its part to be performed or satisfied

Company will reimburse the Underwriters severally upon demand for all out-of-

     and are validly existing as corporations in good standing under the laws of
     their respective jurisdictions of incorporation and are duly qualified to
     transact business as foreign corporations and are in good standing under
     the laws of all other jurisdictions where the ownership or leasing of their

          (i)  such Selling Stockholder has full corporate power to enter into
     this Agreement, the Custody Agreement and the Power of Attorney and to
     sell, transfer and deliver the Securities being sold by such Selling
     Stockholder hereunder in the manner provided in this Agreement and to

     such Selling Stockholder, subject to applicable bankruptcy, insolvency and
     similar laws affecting creditors' rights generally and subject, as to
     enforceability, to general principles of equity (regardless of whether
     enforcement is sought in a proceeding in equity or at law);

          (ii)  the delivery by such Selling Stockholder to the several
     Underwriters of certificates for the Securities being sold hereunder by
     such Selling Stockholder against payment therefor as provided herein, will
     convey good and marketable title to such Securities to the several
     Underwriters, free and clear of all security interests, liens,
     encumbrances, equities, claims or other defects;

          (iii)   the sale of the Securities to the Underwriters by such Selling
     Stockholder pursuant to this Agreement, the compliance by such Selling
     Stockholder with the other provisions of this Agreement, the Custody
     Agreement and the consummation of the other transactions herein
     contemplated do not (A) require the consent, approval, authorization,
     registration or qualification of or with any governmental authority, except
     such as have been obtained and such as may be required under state
     securities or blue sky laws, or (B) conflict with or result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under any indenture, mortgage, deed of trust, lease or other agreement or

     Selling Stockholder is bound, or any statute or any judgment, decree,
     order, rule or regulation of any court or other governmental authority or
     any arbitrator applicable to such Selling Stockholder.

     In rendering such opinion, such counsel may rely, as to matters of fact, to
the extent such counsel deem proper, on certificates of responsible officers of
the Company and public officials and, as to matters involving the application of
laws of any jurisdiction other than the State of Massachusetts or the United
States, to the extent satisfactory in form and scope to counsel for the
Underwriters, upon the opinion of Holland & Knight LLP.  The foregoing opinion

opinion of and copies of such opinion shall be delivered to the Representatives
and counsel for the Underwriters.]

with respect to the issuance and sale of the Firm Securities, the Registration
Statement and the Prospectus, and such other related matters as the
Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as they may reasonably request for the purpose of

LLP [, Fred Wilson, Esq.] and [INSERT NAMES OF LOCAL COUNSEL TO SUBSIDIARIES]
                              -----------------------------------------------
referred to in paragraphs (b) and (c) above.

     (e) The Representatives shall have received from PricewaterhouseCoopers LLC
a letter or letters dated, respectively, the date hereof and the Firm Closing
Date, in form and substance satisfactory to the Representatives, to the effect
that:

          (i) they are independent accountants with respect to the Company and
     its consolidated subsidiaries within the meaning of the Act and the
     applicable rules and regulations thereunder;

          (ii) in their opinion, the audited consolidated financial statements
     and schedules and pro forma financial statements examined by them and
     included in the Registration Statement and the Prospectus comply in form in
     all material respects with the applicable accounting requirements of the
     Act and the related published rules and regulations;

                                       15
<PAGE>

          (iii)  on the basis of a reading of the interim unaudited consolidated
     condensed financial statements of the Company and its consolidated
     subsidiaries and carrying out certain specified procedures (which do not
     constitute an examination made in accordance with generally accepted
     auditing standards) that would not necessarily reveal matters of
     significance with respect to the comments set forth in this paragraph
     (iii), a reading of the minute books of the shareholders, the board of
     directors and any committees thereof of the Company and each of its
     consolidated subsidiaries, and inquiries of certain officials of the
     Company and its consolidated subsidiaries who have responsibility for
     financial and accounting matters, nothing came to their attention that
     caused them to believe that:

               (A) the unaudited consolidated condensed financial statements of
          the Company and its consolidated subsidiaries included in the
          Registration Statement and the Prospectus do not comply in form in all
          material respects with the applicable accounting requirements of the
          Act and the related published rules and regulations thereunder or are
          not in conformity with generally accepted accounting principles
          applied on a basis substantially consistent with that of the audited
          consolidated financial statements included in the Registration
          Statement and the Prospectus;

               (B) at a specific date not more than five business days prior to
          the date of such letter, there were any changes in the capital stock
          or long-term debt of the Company and its consolidated subsidiaries or
          any decreases in not current assets or stockholders' equity of the
          Company and its consolidated subsidiaries, in each case compared with
          amounts shown on the December 31, 1999 consolidated balance sheet
          included in the Registration Statement and the Prospectus, or for the
          period from January 1, 2000 to such specified date there were any
          decreases, as compared with the period from October 1, 1999 to the
          comparable specified date in [November] 1999, in sales, net revenues,
          income before  income taxes or total or per share amounts of net
          income of the Company and its consolidated subsidiaries, except in all
          instances for changes, decreases or increases set forth in such
          letter;

          (iv) they have carried out certain specified procedures, not
     constituting an audit, with respect to certain amounts, percentages and
     financial information that are derived from the general accounting records
     of the Company and its consolidated subsidiaries and are included in the
     Registration Statement and the Prospectus under the captions
     "Capitalization," Dilution," "Management's Discussion and Analysis of
     Financial Condition and Results of Operations" and "Business" and in
     Exhibit 11 to the Registration Statement, and have compared such amounts,
     percentages and financial information with such records of the Company and
     its consolidated subsidiaries and with information derived from such
     records and have found them to be in agreement, excluding any questions of
     legal interpretation; and

          (v)  on the basis of a reading of the unaudited pro forma consolidated
     condensed financial statements included in the Registration Statement and
     the Prospectus, carrying out certain specified procedures that would not
     necessarily reveal matters of significance with respect to the comments set
     forth in this paragraph (v), inquiries of certain officials of the Company
     and its consolidated subsidiaries who have responsibility for financial and
     accounting matters and proving the arithmetic accuracy of the application
     of the pro forma adjustments to the historical amounts in the unaudited pro
     forma consolidated condensed financial statements, nothing came to their
     attention that caused them to believe that the unaudited pro forma
     consolidated condensed financial statements do not comply in form in all
     material respects with the applicable accounting requirements of Rule 11-02
     of Regulation S-X or that the pro forma adjustments have not been properly
     applied to the historical amounts in the compilation of such statements.

     In the event that the letters referred to above set forth any such changes,
decreases or increases, it shall be a further condition to the obligations of
the Underwriters that (A) such letters shall be accompanied by a written
explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

     References to the Registration Statement and the Prospectus in this
paragraph (d) with respect to either letter referred to above shall include any
amendment or supplement thereto at the date of such letter.

                                       16

     the Company has performed all covenants and agreements and satisfied all
     conditions on its part to be performed or satisfied at or prior to the Firm
     Closing Date;

     given in the Registration Statement and the Prospectus, neither the Company
     nor any of its subsidiaries has sustained any material loss or interference

     accident or other calamity, whether or not covered by insurance, or from
     any labor dispute or any legal or governmental proceeding, and there has
     not been any material adverse change, or any development involving a
     prospective material adverse change, in the condition (financial or
     otherwise), management, business prospects, net worth or results of
     operations of the Company or any of its subsidiaries, except in each case
     as described in or contemplated by the Prospectus (exclusive of any
     amendment or supplement thereto).

     (g) The Representatives shall have received from each person who is a
director or officer of the Company and all individuals who own shares or options
to purchase such shares of Common Stock an agreement to the effect that such
person will not, directly or indirectly, without the prior written consent of
Prudential Securities Incorporated, on behalf of the Underwriters, offer, sell,

of any shares of Common Stock or any securities convertible into, or
exchangeable or exercisable for, shares of Common Stock for a period of 180 days
after the date of this Agreement.

     (h)  The Representatives shall have received a certificate from each
Selling Stockholder, signed by such Selling Stockholder, dated the Firm Closing

     specifically for use therein, the Registration Statement, as amended as of

Securities Exchange Act of 1934 (the "Exchange Act"), against any losses,

such controlling person may become subject under the Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of, caused by, related to, based upon or arising out of or in
connection with:

          (i) any untrue statement or alleged untrue statement made by the
     Company, the Selling Stockholders or Peter S. Dawson in Section 2 of this
     Agreement,

          (ii) any untrue statement or alleged untrue statement of any material

     any jurisdiction in order to qualify the Securities under the securities or
     blue sky laws thereof or filed with the Commission or any securities
     association or securities exchange (each an "Application"),

          (iii)  the omission or alleged omission to state in the Registration
     Statement or any amendment thereto, any Preliminary Prospectus or the

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company, the Selling
                             --------  -------
Stockholders and Peter S. Dawson will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement or any amendment thereto, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or
any Application in reliance upon and in conformity with written information

Selling Stockholders and Peter S. Dawson will not be liable to any Underwriter
or any person controlling such Underwriter with respect to any such untrue
statement or omission made in any Preliminary Prospectus that is corrected in

Underwriter but was not sent or given a copy of the Prospectus (as amended or
supplemented) at or prior to the written confirmation of the sale of such
Securities to such person in any case where such delivery of the Prospectus
(as amended or supplemented) is required by the Act, unless such failure to
deliver the Prospectus (as amended or supplemented) was a result of
noncompliance by the Company, the Selling Stockholders or Peter S. Dawson with
Sections 5(a)(iv) and 5(a)(v) of this Agreement. This indemnity agreement will
be in addition to any liability which the Company, the Selling Stockholders and
Peter S. Dawson may otherwise have, provided, however, that in no event shall
                                    --------  -------

commissions, from the Underwriters in the offering (if any), and (ii) the amount
which such Selling Stockholder and Peter S. Dawson receive pursuant to any
declared distribution of previously undistributed Subchapter S corporation
income of approximately $4.6 million (the "Distribution"). The Company, the
Selling Stockholders and Peter S. Dawson will not, without the prior written
consent of the Underwriter or Underwriters purchasing, in the aggregate, more
than fifty percent (50%) of the Securities, settle or compromise or consent to
the entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Underwriter or any person who controls any such Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is
a party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of all of the
Underwriters and such controlling persons from all liability arising out of such
claim, action, suit or proceeding.

     (b) Each Underwriter, severally and not jointly, will indemnify and hold
harmless the Company, each of its directors, each of its officers who signed the
Registration Statement, the Selling Stockholders and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses, claims, damages or liabilities to which
the Company or any such director, officer or Selling Stockholder may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement or any amendment thereto, any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
or any Application or (ii) the omission or the alleged omission to state therein
a material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or any Application or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the Representatives
specifically for use therein: and, subject to the limitation set forth
immediately preceding this clause, will reimburse, as incurred, any legal or
other expenses reasonably incurred by the Company or any such director, officer
or such Selling Stockholder in connection with investigating or defending any
such loss, claim, damage, liability or any action in respect thereof. This
indemnity agreement will be in addition to any liability which such Underwriter
may otherwise have.

     (c) Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section 8. In case any such action is brought against any indemnified party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided, however, that if the defendants in any such action include both the
- --------  -------
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties.  After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this

                                       19
<PAGE>

Section 8 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof, unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that in connection with such action the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) in any one action or separate
but substantially similar actions in the same jurisdiction arising out of the
same general allegations or circumstances, designated by the Representatives in
the case of paragraph (a) of this Section 8, representing the indemnified
parties under such paragraph (a) who are parties to such action or actions) or
(ii) the indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party.

     (d) In circumstances in which the indemnity agreement provided for in the
preceding paragraphs of this Section 8 is unavailable or insufficient, for any
reason, to hold harmless an indemnified party in respect of any losses, claims,
damages or liabilities (or actions in respect thereof), each indemnifying party,
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect (i) the relative benefits received by
the indemnifying party or parties on the one hand and the indemnified party on
the other from (A) the offering of the Securities and (B) the proceeds from the
Distribution, or (ii) if the allocation provided by the foregoing clause (i) is
not permitted by applicable law, not only such relative benefits but also the
relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements or omissions or
alleged statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations.  The relative benefits received by the Company, the
Selling Stockholders and Peter S. Dawson on the one hand and the Underwriters on
the other shall be deemed to be in the same proportion as the total proceeds
from the offering (before deducting expenses) received by the Company and the
Selling Stockholders bear to the total underwriting discounts and commissions
received by the Underwriters.  The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, the Selling
Stockholders, Peter S. Dawson or the Underwriters, the parties' relative
intents, knowledge, access to information and opportunity to correct or prevent
such statement or omission, and any other equitable considerations appropriate
in the circumstances.  The Company, the Selling Stockholders, Peter S. Dawson
and the Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take into account the equitable considerations
referred to above in this paragraph (d).  Notwithstanding any other provision of
this paragraph (d), no Underwriter shall be obligated to make contributions
hereunder that in the aggregate exceed the total public offering price of the
Securities purchased by such Underwriter under this Agreement, less the
aggregate amount of any damages that such Underwriter has otherwise been
required to pay in respect of the same or any substantially similar claim, and
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute hereunder are several in proportion to their respective underwriting
obligations and not joint, and contributions among Underwriters shall be
governed by the provisions of the Prudential Securities Incorporated Master
Agreement Among Underwriters.  For purposes of this paragraph (d), each person,
if any, who controls an Underwriter within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act shall have the same rights to contribution as
such Underwriter, and each director of the Company, each officer of the Company
who signed the Registration Statement and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, shall have the same rights to contribution as the Company.

     9.   Default of Underwriters.  If one or more Underwriters default in their
          -----------------------
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities

                                       20
<PAGE>

that such defaulting Underwriter or Underwriters agreed but failed to purchase.
If one or more Underwriters so default with respect to an aggregate number of
Securities that is more than ten percent of the aggregate number of Firm
Securities or Option Securities, as the case may be, to be purchased by all of
the Underwriters at such time hereunder, and if arrangements satisfactory to the
Representatives are not made within 36 hours after such default for the purchase
by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company, the Selling
Stockholders and Peter S. Dawson, other than as provided in Section 10 hereof.
In the event of any default by one or more Underwriters as described in this
Section 9, the Representatives shall have the right to postpone the Firm Closing
Date or the Option Closing Date, as the case may be, established as provided in
Section 3 hereof for not more than seven business days in order that any
necessary changes may be made in the arrangements or documents for the purchase
and delivery of the Firm Securities or Option Securities, as the case may be.
As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 9. Nothing herein shall
relieve any defaulting Underwriter from liability for its default.

     10.  Survival.  The respective representations, warranties, agreements,
          --------
covenants, indemnities and other statements of the Company, its officers, the
Selling Stockholders, Peter S. Dawson and the several Underwriters set forth in
this Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement shall remain in full force and effect, regardless of (i) any
investigation made by or on behalf of the Company, any of its officers or
directors, the Selling Stockholders, Peter S. Dawson, any Underwriter or any
controlling person referred to in Section 8 hereof and (ii) delivery of and
payment for the Securities.  The respective agreements, covenants, indemnities
and other statements set forth in Sections 6 and 8 hereof shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement.

     11.  Termination.  (a) This Agreement may be terminated with respect to the
          -----------
Firm Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company  given prior to the Firm Closing Date
or the related Option Closing Date, respectively, in the event that the Company,
the Selling Stockholders and Peter S. Dawson shall have failed, refused or been
unable to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder at or prior thereto or, if at or prior to the
Firm Closing Date or such Option Closing Date, respectively,

          (i) the Company or any of its subsidiaries shall have, in the sole
     judgment of the Representatives, sustained any material loss or
     interference with their respective businesses or properties from fire,
     flood, hurricane, accident or other calamity, whether or not covered by
     insurance, or from any labor dispute or any legal or governmental
     proceeding or there shall have been any material adverse change, or any
     development involving a prospective material adverse change (including
     without limitation a change in management or control of the Company), in
     the condition (financial or otherwise), business prospects, net worth or
     results of operations of the Company and its subsidiaries, except in each
     case as described in or contemplated by the Prospectus (exclusive of any
     amendment or supplement thereto);

          (ii) trading in the Common Stock shall have been suspended by the
     Commission or the Nasdaq National Market or trading in securities generally
     on the New York Stock Exchange or Nasdaq National Market shall have been
     suspended or minimum or maximum prices shall have been established on
     either such exchange or market system;

          (iii)  a banking moratorium shall have been declared by New York or
     United States authorities; or

          (iv) there shall have been (A) an outbreak or escalation of
     hostilities between the United States and any foreign power, (B) an
     outbreak or escalation of any other insurrection or armed conflict
     involving the United States or (C) any other calamity or crisis or material
     adverse change in general economic, political or financial conditions
     having an effect on the U.S. financial markets that, in the sole judgment
     of the Representatives, makes it impractical or inadvisable to proceed with
     the public offering or the delivery of the Securities as contemplated by
     the Registration Statement, as amended as of the date hereof.

     (b) Termination of this Agreement pursuant to this Section 11 shall be
without liability of any party to any other party, except as provided in Section
10 hereof.

Embedded Support Tools Corporation
120 Royall Street
Canton, MA 02021

     Re:    Registration Statement on Form S-1
            ----------------------------------

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a Registration
Statement on Form S-1 (File No. 333-93409) (the "Registration Statement") filed
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act"), for the registration
of an aggregate of 5,175,000 shares of Common Stock, $.10 par value per share
(the "Shares"), of Embedded Support Tools Corporation, a Massachusetts
corporation (the "Company"), of which (i) up to 4,500,000 Shares (including
400,000 Shares issuable upon exercise of an over-allotment option granted by the
Company) will be issued and sold by the Company and (ii) up to 600,000 Shares
(including 200,000 Shares issuable upon exercise of an over-allotment option
granted by a certain stockholder) will be sold by certain stockholders of the
Company (the "Selling Stockholders).


     The Shares are to be sold by the Company and the Selling Stockholders
pursuant to an underwriting agreement (the "Underwriting Agreement") to be
entered into by and among the Company, the Selling Stockholders and Prudential
Securities Incorporated, Chase Securities Inc. and Needham & Company, Inc., as
representatives of the several underwriters named in the Underwriting Agreement,
the form of which has been filed as Exhibit 1 to the Registration Statement.

     We are acting as counsel for the Company in connection with the sale by the
Company and James E. Watkins of the Shares. We have examined signed copies of
the Registration Statement as filed with the Commission. We have also examined
and relied upon the Underwriting Agreement, minutes of
<PAGE>

meetings of the stockholders and the Board of Directors of the Company as
provided to us by the Company, stock record books of the Company as provided to
us by the Company, the Certificate of Incorporation and By-Laws of the Company,
each as restated and/or amended to date, and such other documents as we have
deemed necessary for purposes of rendering the opinions hereinafter set forth.

     In our examination of the foregoing documents, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as copies, the authenticity of the originals of such latter documents and the
legal competence of all signatories to such documents.

     We assume that the appropriate action will be taken, prior to the offer and
sale of the Shares in accordance with the Underwriting Agreement, to register
and qualify the Shares for sale under all applicable state securities or "blue
sky" laws.

     We express no opinion herein as to the laws of any state or jurisdiction
other than the state laws of the Commonwealth of Massachusetts and the federal
laws of the United States of America. To the extent that any other laws govern
the matters as to which we are opining herein, we have assured that such laws
are identical to the state laws of the Commonwealth of Massachusetts, and we are
expressing no opinion herein as to whether such assumption is reasonable or
correct.

     Based upon and subject to the foregoing, we are of the opinion that (i) the
Shares to be issued and sold by the Company have been duly authorized for
issuance and, when such Shares are issued and paid for in accordance with the
terms and conditions of the Underwriting Agreement, such Shares will be validly
issued, fully paid and nonassessable and (ii) the Shares to be sold by the
Selling Stockholders have been duly authorized and are validly issued, fully
paid and nonassessable.

     It is understood that this opinion is to be used only in connection with
the offer and sale of the Shares while the Registration Statement is in effect.

     Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters. This opinion
is based upon currently existing statutes, rules, regulations and judicial
decisions, and we disclaim any obligation to advise you of any change in any of
these sources of law or subsequent legal or factual developments which might
affect any matters or opinions set forth herein.

          (f) "Insured Loss" shall mean damage or destruction which was caused
by an event required to be covered by the insurance described in paragraph 8.
The fact that an insured Loss has a deductible amount shall not make the loss an
uninsured loss.

          (g) "Replacement Cost" shall mean the amount of money necessary to be

if at any time during the term of this Lease there is damage which is an Insured
Loss and which falls into the classification of either Premises Damage or
Premises Building Partial Damage, then Lessor shall, as soon as reasonably
possible and to the extent the required materials and labor are readily
available through usual commercial channels, at Lessor's expense, repair such
damage (but not Lessee's fixtures, equipment or tenant improvements originally
paid for by Lessee) to its condition existing at the time of the damage, and
this Lease shall continue in full force and effect.

          (b) Uninsured Loss: Subject to the provisions of paragraphs 9.4 and
9.5, if at any time during the term of this Lease there is damage which is not
an Insured Loss and which falls within the classification of Premises Damage or
Premises Building Partial Damage, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense), which
damage prevents Lessee from making any substantial use of the Premises, Lessor
may at Lessor's option either (i) repair such damage as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) give written notice to Lessee within thirty (30) days
after the date of the occurrence of such damage of Lessor's intention to cancel

condition existing at the time of the damage, but not Lessee's fixtures,
equipment or tenant improvements, and this Lease shall continue in full force
and effect, or (ii) give written notice to Lessee within thirty (30) days after
the date of occurrence of such damage of Lessor's intention to cancel and
terminate this Lease, in which case this Lease shall terminate as of the date of
the occurrence of such damage.

     9.4  Damage Near End of Term.
          ------------------------

          (a) Subject to paragraph 9.4(b), if at any time during the last twelve

written notice to Lessee of Lessor's election to do so within 30 days after the
date of occurrence of such damage.

          (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an
option to extend or renew this Lease, and the time within which said option may

be exercised at all, no later than twenty (20) days after the occurrence of an
Insured Loss falling within the classification of Premises Damage during the
last twelve (12) months of the term of this Lease.  If Lessee exercises such
option during said twenty (20) days period, Lessor shall at Lessor's expense,
repair such damage, but not Lessee's fixtures, equipment or tenant improvements,
as soon as reasonably possible and this Lease shall continue in full force and
effect.  If Lessee fails to exercise such option during said twenty (20) day
period, then Lessor may at Lessor's option terminate and cancel this Lease as of
the expiration of said twenty (20) day period by giving written notice to Lessee
of Lessor's election to do so within ten (10) days after the expiration of said
twenty (20) day period, notwithstanding any term or provision in the grant of
option to the contrary.

     9.5  Abatement of Rent; Lessee's Remedies.
          ------------------------------------

          (a) In the event Lessor repairs or restores the Building or Premises
pursuant to the provisions of this paragraph 9, and any part of the Premises are
not usable (including loss of use due to loss of access or essential services),
the rent payable hereunder (including Lessee's Share of Operating Expense
increase) for the period during which such damage, repair or restoration
continues shall be abated, provided (1) the damage was not the result of the
negligence of Lessee, and (2) such abatement shall only be to the extent the
operation and profitability of Lessee's business as operated on the Premises is
adversely affected.  Except for said abatement of rent, if any, Lessee shall
have no claim against Lessor for any damage suffered by reason of any such
damage, destruction, repair or restoration.

          (b) If Lessor shall be obligated to repair or restore the Premises or
the Building under the provisions of this Paragraph 9 and shall not commence
such repair or restoration within ninety (90) days after such occurrence, or if
Lessor shall not complete the restoration and repair within six (6) months after
such occurrence. Lessee may at Lessee's option cancel and terminate this Lease
by giving Lessor written notice of Lessor's election to do so at any time prior
to the commencement or

                                      -13-
<PAGE>

completion, respectively, of such repair or restoration, in such event this
Lease shall terminate as of the date of such notice.

restoration and repair, including but not limited to the approval and/or
execution of plans and specifications required.

addition, return to Lessee so much of Lessee's security deposit as has not
theretofore been applied by Lessor.

     9.7  Waiver.  Lessor and Lessee waive the provisions of any statute which
          ------
relate to termination of leases when leased property is destroyed and agree that
such event shall be governed by the terms of this Lease.

Real Property Taxes.
- --------------------

     10.1  Payment of Taxes.  Lessor shall pay the real property tax as defined
           ----------------
in paragraph 10.3, applicable to the Office Building Project subject to
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2.

     10.2  Additional Improvements.  Lessee shall not be responsible for paying
           -----------------------
any increase in real property tax specified in the tax assessor's records and
work sheets as being caused by additional improvements placed upon the Office
Building Project by other lessees or by Lessor for the exclusive enjoyment of
any other lessee.  Lessee shall, however, pay to Lessor at the time that
Operating Expenses are payable under paragraph 4.2(c) the entirety of any
increase in real property tax if assessed solely by reason of additional
improvements placed upon the Premises by Lessee or at Lessee's request.

     10.3  Definition of "Real Property Tax."  As used herein, the term "real
           --------------------------------
property tax" shall include any form of real estate tax or assessment, general,
ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Office Building Project or any portion thereof
by any authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement thereof, against any legal or
equitable interest of Lessor in the Office Building Project or in any portion
thereof, as against Lessor's right to rent or other income therefrom, and as
against Lessor's business of leasing the Office Building Project.  The term
"real property tax" shall also include any tax, fee, or assessment of charge
(i) in substitution of, partially or totally, any tax, fee, levy, assessment or
charge hereinabove included within the definition of "real property

                                      -14-
<PAGE>

tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a right not
charged prior to June 1, 1979, or, if previously charged, has been increased
since June 1, 1978, or (iv) which is imposed as a result of a change in
ownership, as defined by applicable local statutes for property tax purposes, of
the Office Building Project or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such change of
ownership, or (v) which is imposed by reason of this transaction, any
modifications or changes hereto, or any transfers hereof.

     10.4  Joint Assessment.  If the improvements or property, the taxes for
           ----------------
which are to be paid separately by Lessee under paragraph 10.2 or 10.5 are
separately assessed, Lessee's portion of that tax shall be equitably determined
by Lessor from the respective valuations assigned in the assessor's worksheets
or such other information (which may include the cost of construction) as may be
reasonably available.  Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

     10.5  Personal Property Taxes.

           (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.

           (b) If any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.

Utilities.
- ---------

     11.1  Services Provided by Lessor.  Lessor shall provide heating,
           ---------------------------
ventilation, air conditioning, and janitorial service as reasonably required,
reasonable amounts of electricity for normal lighting and office machines, water
for reasonable and normal drinking and lavatory use, and replacement light bulbs
and/or fluorescent tubes and ballasts for standard overhead fixtures.

     11.2  Services Exclusive to Lessee.  Lessee shall pay for all water, gas,
           ----------------------------
heat, light, power, telephone and other utilities and services specially or
exclusively supplied and/or metered exclusively to the Premises or to Lessee,
together with any taxes thereon.  If any such services are not separately
supplied to the Premises, Lessee shall pay at Lessor's option, either Lessee's
Share or a reasonable proportion to be determined by Lessor of all charges
jointly, metered with other premises in the Building.

     11.3  Hours of Service.  Said services and utilities shall be provided
           ----------------
during generally accepted business days and hours or such other days or hours as
may

                                      -15-
<PAGE>

hereafter be set forth. Utilities and services required at other times shall be
subject to advance request and reimbursement by Lessee to Lessor of the cost
thereof.

     11.4  Excess Usage by Lessee.  Lessee shall not make connection to the
           ----------------------
utilities except by or through existing outlets and shall not install or use
machinery or equipment on the Premises that uses excess water, lighting or
power, or suffer or permit any act that causes extra burden upon utilities or
services, including but not limited to security services, over standard office
usage for the Office Building Project.  Lessor shall require Lessee to reimburse
Lessor for any excess expenses or costs that may arise out of a breach of this
subparagraph by Lessee.  Lessor may, in its sole discretion, install equipment
and/or separate metering applicable to Lessee's excess usage or loading.

     11.5  Interruptions.  There shall be no abatement of rent and Lessor shall
           -------------
not be liable in any respect whatsoever for the inadequacy, stoppage,
interruption or delay in utility or service due to riot, strike, labor dispute,
breakdown, accident, repair or other cause beyond Lessor's reasonable control.

Assignment and Subletting.
- -------------------------

     12.1  Lessee shall not voluntarily or by operation of law assign, transfer,
mortgage, sublet, or otherwise transfer or exchange all or any part of Lessee's
interest in the Lease or in the Premises, without Lessor's prior written
consent, which Lessor shall not unreasonably withhold.  Lessor shall respond to
Lessee's request for consent hereunder in a timely manner and any attempted
assignment, transfer, mortgage, or encumbrance shall be void, and shall
constitute a material default and breach of this Lease without the need for
notice within the meaning of this paragraph 12 shall include the transfer or
transfers aggregating:  (a) if Lessee is a corporation, more than twenty-five
percent (25%) of the voting stock of such corporation, or (b) if Lessee is a
partnership, more than twenty-five percent (25%) of the profit and loss
participation in such partnership.

     12.2  Notwithstanding the provisions of paragraph 12.1 hereof, Lessee may
assign or sublet the Premises, or any portion thereof, without Lessor's consent,
to any corporation which controls, is controlled by or is under common control
with Lessee, or to any corporation resulting in the merger or consolidation with
Lessee, or to any person or entity which acquires all the assets of Lessee as a
going concern of the business and is being conducted on the Premises all of
which are referred to as "Lessee Affiliate"; provided that before such
assignment shall be effective, said Affiliate of Lessee under this Lease and
(b) Lessor shall be given written notice of such assignment and assumption.

     12.3  Terms and Conditions Applicable to Assignment and Subletting.
           ------------------------------------------------------------

           (a) No assignment or subletting shall release Lessee of Lessee's
obligations hereunder or alter the primary ability of Lessee to pay the rent or
other

                                      -16-
<PAGE>

sums due Lessor hereunder including Lessee's Share of Operating Expense
Increase, and to perform all other obligations to be performed by Lessee
hereunder.

           (b) Lessee shall allow no other party other than Lessee pending
approval or disapproval of such assignment.

           (c) Neither a delay in the approval or disapproval of such assignment
or subletting, nor the acceptance of rent, shall constitute a waiver or
renouncement of Lessor's claim for the breach of any of the terms or conditions
of this paragraph 12 or this Lease.

           (d) If Lessee's obligations under this Lease have been guaranteed by
third parties, then an assignment or sublease, and Lessor's consent to such
shall not be effective unless said guarantors give their written consent to such
sublease and the terms thereof.

           (e) The assignment or subletting shall not constitute a consent to
any subsequent assignment or subletting by Lessee in regards to any subsequent
or successive assignment or subletting by the sublessee. However, Lessor may
consent to subsequent sublettings and assignments of a sublease or any
amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining prior consent and such
action shall not relieve such persons from liability under this Lease or said
sublease; however, such persons shall not be responsible to the extent any such
amendment or modification enlarges or increases the obligations of the Lessee or
sublessee under this Lease or any sublease.

           (f) In the event of any default under this Lease, Lessor may proceed
directly against Lessee, any guarantors or any one else responsible for
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible to Lessor, of
any security held by Lessor or Lessee.

           (g) Lessor's written consent to any assignment or subletting of the
Premises by Lessee shall not constitute an acknowledgement that no default
exists under this Lease of the obligations to be performed by Lessee nor shall
such consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

           (h) The discovery of the fact that any financial statement relied
upon by Lessor in giving its consent to an assignment or subletting was
materially false shall, at Lessor's election, render Lessor's said consent null
and void.

     12.4  Additional Terms and Conditions Applicable to Subletting.  Regardless
           --------------------------------------------------------
of Lessor's consent, the following terms and conditions shall apply to any
subletting

                                      -17-
<PAGE>

by Lessee of all or any part of the Premises and shall be deemed included in all
subleases under this Lease whether or not expressly incorporated therein:

           (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
otherwise made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the collection of rents from a sublessee, be
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such lessee under such sublease. Lessee
hereby irrevocably authorizes and directs any such sublessee, upon receipt of a
written notice from Lessor that a default exists in the performance of Lessee's
obligations under this Lease, to pay to Lessor the rents due and to become due
under the lease. Lessee agrees that such sublessee shall have the right to reply
upon any such statement and request from Lessor, and that such sublessee shall
pay such rents to Lessor without any obligation or right to inquire as to
whether such default exists and notwithstanding any notice from or claim from
Lessor to the contrary. Lessee shall have no right or claim against said
sublessee or Lessor for any such rents so paid by said sublessee to Lessor.

           (b) No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor. In entering into any sublease,
Lessee shall use only such form of sublessee as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent. Any sublease shall, by reason of entering into a
sublease under this Lease, be deemed, for the benefit of Lessor, have assumed
and agreed to conform and comply with each and every obligation herein to be
performed by Lessee other than such obligations as contrary to or inconsistent
with provisions contained in a sublease of which Lessor has expressly consented
in writing.

           (c) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor at its option and without any obligation to
do so may require any sublessee to attorn to Lessor, in which event Lessor shall
undertake the obligations of Lessee under such sublease from the time of the
exercise of said option to the termination of such sublease; provided, however,
Lessor shall not be liable for any prepaid rents or security deposit paid by
such sublessee to Lessee or for any other prior defaults of Lessee under such
sublease.

           (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

                                      -18-
<PAGE>

           (e) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within three (3) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

     12.5  Lessor's Expenses.  In the event Lessee shall assign or sublet the
           -----------------
Premises or request the consent of Lessor to any assignment or subletting Lessee
shall request the consent of Lessor for any-act Lessee proposes to do then
Lessee shall pay Lessor's reasonable costs and expenses in connection therewith,
including attorneys;  architects; engineers' or other consultants' fees.

     12.6  Conditions by Consent.  Lessor reserves the right to condition any
           ---------------------
approval to assign or sublet upon Lessor's determination that (a) the proposed
assignee or sublessee shall conduct a business on the Premises of a quality
substantially equal to that of Lessee and consistent with the general character
of the other occupants to the Office Building Project and not in violation of
any exclusives or rights then held by other tenants, and (b) the proposed
assignee or sublessee be at least as financially responsible as Lessee was
expected to be at the time of the execution of this Lease or of such assignment,
whichever is greater.

Default; Remedies.
- ------------------

     13.1  Default.  The occurrence of any one or more of the following events
           -------
shall constitute a material default of this Lease by Lessee:

           (a) The vacation or abandonment of the Premises by Lessee. Vacation
of the Premises shall include the failure to occupy the Premises for a
continuous period of sixty (60) days or more, whether or not the rent is paid.

           (b) The breach by Lessee of any of the covenants, conditions or
provisions of paragraphs 7.3(a), (b) or (d) (alterations), 12.1 (assignment or
subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 13.1(f)
(false statement), 16(a) (estoppel certificate), 30(b) (subordination) or 41.1
(easements), all of which are hereby deemed to be material, non-curable defaults
without the necessity of any notice by Lessor to Lessee thereof.

           (c) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, and if such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the Notice required by
this subparagraph.

                                      -19-
<PAGE>

           (d) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Lessee
other than those referenced in subparagraphs (b) and (c), above, where such
failure shall continue for a period of thirty (30) days after written notice
thereof from Lessor to Lessee; provided, however, that if the nature of Lessee's
noncompliance is such that more than thirty (30) days are reasonably required
for its cure, then Lessee shall not be deemed to be in default if Lessee
commenced such cure within said thirty (30) day period and notice required to be
given to Lessee under applicable Unlawful Detainer statutes.

           (e) (i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as
defined in 11 U.S.C. (S)101 or any successor statute thereto (unless, in the
case of a petition filed against Lessee, the same is dismissed within sixty (60)
days; (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.  In the event that any provision of this paragraph 13.1(3) is contrary to
any applicable law, such provision shall be of no force or effect.

           (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee, or its successor in interest or by any guarantor of Lessee's
rights hereunder, was materially false.

     13.2  Remedies.  In the event of any material default or breach of this
           --------
Lease by Lessee, Lessor may at any time thereafter, with or without notice and
without limiting Lessor in the exercise of any right of remedy which Lessor may
have by reason of such default:

           (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender, possession of the Premises to Lessor, in
such event Lessor shall be entitled to recover from Lessee all damages incurred
by Lessor by reason of Lessee's default, including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

                                      -20-
<PAGE>

           (b) Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor'
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

           (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3  Default by Lessor.  Lessor shall not be in default unless Lessor
           -----------------
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such 30-day period and thereafter
diligently pursues the same to completion.

     13.4  Late Charges.  Lessee hereby acknowledges that the late payment by
           ------------
Lessee to Lessor of Base Rent, Lessee's Share of Operating Expense and or other
sums due hereunder will cause Lessor to incur costs not contemplated by this
Lease, the exact amount of which will be extremely difficult to ascertain.  Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Office Building Project.  Accordingly, if any
installment of Base Rent, Operating Expenses and or any other sum due from
Lessee shall not be received by Lessor or Lessor's designee within ten (10) days
after such amount shall be due.  Lessee, without any requirement for notice to
Lessor, Lessee shall pay to Lessor a later charge equal to 8% of such overdue
amount.  The parties hereby agree that such later charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee.  Acceptance of such later charge by Lessor shall in not event constitute
a waiver of Lessee's default with respect to such overdue amount, nor prevent
Lessor from exercising any of the other rights and remedies granted hereunder.

Condemnation.  If the Premises or any portion thereof or the Office Building
- ------------
Project are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation").
This Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs; provided that if so
much of the Premises or the Office Building Project is taken by such
condemnation as would

                                      -21-
<PAGE>

substantially and adversely affect the operation and profitability of Lessee's
business conducted from the Premises, Lessee shall have the option, to be
exercised only in writing within thirty (30) days after Lessor shall have given
Lessee written notice of such taking (or in the absence of such notice, within
thirty (30) days after the condemning authority shall have taken possession), to
terminate this Lease as of the date the condemning authority takes such
possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the rent and Lessee's Share of Operating
Expense shall be reduced in the proportion that the floor area of the Premises
taken bears to the total floor area of the Premises. Common Areas condemned
shall be excluded from the Common Areas usable by Lessee and no reduction of
rent shall occur with respect thereto or by reason thereof. Lessor shall have
the option in its sole discretion to terminate this Lease as of the taking of
possession by the condemning authority by giving written notice to Lessee of
such election within thirty (30) days after receipt of notice of a taking by
condemnation of any part of the Premises or the Office Building Project. Any
award for the taking of all or any part of the Premises or the Office Building
Project under the power of eminent domain, or any claim made under threat of the
exercise of such power shall be the property of Lessor, whether such award shall
be made as compensation for depreciation in value of the leasehold or for the
taking of the fee, or as severance damages; provided, however, that Lessee shall
be entitled to any separate claim for loss of or damage to Lessee's trade
fixtures, removable personal property and unamortized tenant improvements that
have been paid for by Lessee. For that purpose the cost of such improvements
shall be amortized over the original term of this Lease excluding any options.
In the event that this Lease is not terminated by reason of such condemnation,
Lessor shall to the extent of severance damages received by Lessor in connection
with such condemnation, repair any damage to the Premises caused by such
condemnation except to the extent that Lessee has been reimbursed by the
condemning authority. Lessee shall pay any amount in excess of such severance
damages required to complete such repair.

Broker's Fee.
- ------------

     (a) The brokers involved in this transaction are none "listing broker" and
none as "cooperating broker",  ____________ real estate broker(s).  A
"cooperating Broker" is defined as any broker other than the listing broker
entitled to a share of any commission _________ under this Lease.  Upon
execution of this Lease by both parties, Lessor shall pay to said brokers
jointly, or in such separate shares as they may mutually designate in writing, a
fee as set forth in a separate agreement between Lessor and said broker(s), or
in the event there is no separate agreement between Lessor and said broker(s),
the sum of $0 for brokerage services rendered by said broker(s) to Lessor in
this transaction.

     (b) Lessor further agrees that (i) if Lessee exercises any Option, as
defined in paragraph 39.1 of this Lease, which is granted to Lessee under this
Lease, or any

                                      -22-
<PAGE>

subsequently granted option which is substantially similar to an Option granted
to Lessee under this Lease, or (ii) if Lessee acquires its rights to the
Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or (iii) if Lessee remains in possession of the Premises
after the expiration of the term of this Lease after Lessee failed to exercise
an Option, or (iv) if said broker(s) are the procuring cause of any other lease
or sale entered into between the parties pertaining to the Premises and/or any
adjacent property in which Lessor has an interest, or (v) if the Base Rent is
increased, whether by agreement to an escalation clause contained herein, then
as to any of said transactions or rent increases. Lessor shall pay said
broker(s) a fee in accordance with the schedule of said broker(s) in effect at
the time of execution of this Lease. Said fee shall be paid at the time such
increased rental is determined.

     (c) Lessor agrees to pay said free not only on behalf of Lessor but also on
behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder.  Any transferee of Lessor's interest in this Lease, or other such
transfer is by agreement or by operation of law, shall be deemed to have assumed
Lessor's obligation under this paragraph 15.  Each listing and cooperating
broker shall be a third party beneficiary of the provisions of this paragraph 15
to the extent of their interest in any commission due under this Lease and may
enforce that right directly against Lessor; provided, however, that all brokers
having a right to any part of such total commission shall be a necessary party
to any suit with respect thereto.

     (d) Lessee and Lessor each represent and warrant to the other that neither
has had any dealing with any person, firm, broker or finder (other than the
person(s), if any, whose names are set forth in paragraph 15(a), above) in
connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and no other broker or other person, firm or
entity is entitled to any commission or finder's fee in connection with said
transaction and Lessee and Lessor do each hereby indemnify and hold the other
harmless from and against any costs, expenses, attorneys' fees or liability for
compensation or charges which may be claimed by any such unnamed broker, finder
or other similar party by reason of dealings or actions of the indemnifying
party.

Estoppel Certificate.
- --------------------

     (a) Each party (as "responding party") shall at any time upon not less than
ten (10) days' prior written notice from the other party ("requesting party")
execute, acknowledge and deliver to the requesting party a statement in writing
(i) certifying that this Lease is unmodified and in full force and effect (or,
if modified, stating the nature of such modification and certifying that this
Lease, as so modified, is in full force and effect) and the date which the rent
and other charges are paid in advance, if any, and (ii) acknowledging that there
are not, to the responding party's

                                      -23-
<PAGE>

knowledge, any default on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Office Building Project or
of the business of Lessee.

     (b) AT the requesting party's option, the failure to deliver such statement
within such time shall be a material default of this Lease by the party
requested to respond, without any further notice to such party, or it shall be
conclusive upon such party that (i) this Lease is in full force and effect, and
no modification except as may be represented by the requesting party, (ii) there
are no uncured defaults in the requesting party's performance, (iii) if Lessor
is the requesting party, not more than one months' rent has been paid in
advance.

     (c) If Lessor desires to finance, refinance, or sell the Office Building
Project, or any part thereof, Lessee hereby agrees to deliver to any lender
purchaser designated by Lessor such financial statements of Lessee as may be
reasonably required by such lender or purchaser.  Such statements will include
the past three (3) years' financial statements of Lessee.  All such financial
statements shall be received by Lessor and such lender of purchaser in
confidence and shall be used only for the purposes herein set forth.

- ---------
owners, at the time in question, of the fee title or a lessee's interest in a
ground lease of the Office Building Project, and except as expressly provided in
paragraph 15. In the event of any transfer of such title interest, Lessor herein
named (and in case of any subsequent transfers then the grantor) shall be
relieved from and after the date of such transfer liability as respects Lessor's
obligations thereafter to be performed, provided that any funds in the hands of
Lessor or the then grantor at the time of such transfer, in which Lessee has an
interest, shall be delivered to the grantee. The obligations contained in this
Lease to be performed by Lessor or shall, subject as aforesaid, be binding on
Lessor's successors and assigns, only during their respective periods of
ownership.

The invalidity of any provision of this Lease as determined by a court of
competent jurisdiction shall in no way affect the validity of other provisions
hereof.

Interest on Past-due Obligations.  Except as expressly herein provided, any
- --------------------------------
amount due to Lessor not paid when due shall bear interest at the minimum rate
then allowable by law or judgments from the date due.  Payment of such interest
shall not excuse or cure any default by Lessee under this Lease; provided,
however, that interest shall not be payable on late charges incurred by Lessee
nor on any amounts upon which late charges are paid by Lessee.

Time of Essence.  Time is of the essence with respect to the obligations to be
- ---------------
performed under this Lease.

                                      -24-
<PAGE>

Additional Rent.  All monetary obligations of Lessee to Lessor under the terms
- ---------------
of this Lease, including but not limited to Lessee's Share of Operating Expense
increase and any other expenses payable by Lessee hereunder shall be deemed to
be rent.

Incorporation of Prior Agreements; Amendments.  This Lease contains all
- ---------------------------------------------
agreements of the parties with respect to any matter mentioned herein.  Prior or
contemporaneous agreement or understanding pertaining to any such matter shall
be effective.  This Lease may be modified in writing signed by the parties in
interest at the time of the modification.  Except as otherwise stated in this
Lease, Lessee hereby acknowledges that neither real estate broker listed in
paragraph 15 hereof nor any cooperating broker on this transaction nor the
Lessor or any employee or agent of any other persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health
Act, the legal and adaptability of the Premises and the compliance thereof with
all applicable laws and regulations in effect during the term of this Lease.

Notices.  Any notice required or permitted to be given hereunder shall be in
- -------
writing and may be given by personal delivery or by certified or registered
mail, and shall be deemed sufficiently given if delivered or addressed to Lessee
or to Lessor at the address noted below or adjacent to the name of the
respective parties, as the case may be.  Mailed notices shall be deemed given
upon actual receipt at the address required, or forty-eight hours following
deposit in the mail, postage prepaid, whichever first occurs.  Either party may
by notice to the other specify a different address for all purposes except that
upon Lessee's taking possession of the Premises, the Premises shall constitute
Lessee's address for notice purposes and of all notices required or permitted to
be given to Lessor hereunder shall be concurrently transmitted to such party or
parties at such addresses and may from time to time hereafter designate by
notice to Lessee.

Waivers.  No waiver by Lessor of any provision hereof shall be deemed a waiver
- -------
of any other provision hereof or of any subsequent breach by Lessee of the same
or any other provision.  Lessor's consent to, or approval of, any act shall not
be deemed to render unnecessary the obtaining of Lessor's consent to or approval
of any subsequent act by Lessee.  The acceptance of rent hereunder by Lessor
shall not be a waiver of any preceding breach by Lessee of any provision hereof,
other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of the preceding breach at the time of
acceptance of such rent.

Recording.  Either Lessor or Lessee shall, upon request of the other, execute,
- ---------
acknowledge and deliver to the other a "short form" memorandum of Lessee for
recording purposes.

<PAGE>

Holding Over.  If Lessee, with Lessor's consent, remains in possession of the
- ------------
Premises or any part thereof after the expiration of the term hereof.  The new
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, except that rent payable shall be
two hundred percent (200%) of the rent payable immediately preceding the
termination date of this Lease, and all Options, if granted under the terms of
this Lease shall be deemed terminated and be of no further effect during said
month to month tenancy.

Cumulative Remedies.  No remedy or election hereunder shall be deemed exclusive
- -------------------
but shall, wherever possible, be cumulative with all other remedies at law or in
equity.

Binding Effect; Choice of Law.  Subject to any provisions hereof restricting
- -----------------------------
assignment or subletting by Lessee and subject to the provisions of paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns.  This Lease shall be governed by the laws of State where
the Office Building Project is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the City in which the Office
Building Project is located.

Subordination.
- -------------

     (a) This Lease, and any Option or right or first refusal granted hereby, at
Lessor's option, shall be subordinate to any ground lease, mortgage, deed of
trust, or any other hypothecation or security now or hereafter placed upon the
Office Building Project and to any and all advances made on security thereof and
to all renewals, modifications, consolidations, replacements and extensions
thereof.  Notwithstanding such subordination, Lessee's right to quiet possession
of the Premises shall not be disturbed if Lessee is not in default and so long
as Lessee shall pay the rent and continue and perform all of the provisions of
this Lease unless this Lease is otherwise terminated pursuant to its terms.
If any mortgagee, trustee or the Lessor shall elect to have this Lease and any
Options granted hereby prior to the line of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Option shall be deemed prior to such mortgage, deed of trust or ground
lease, whether Lease or such Options are dated prior or subsequent to the date
of said Mortgage, deed of trust or ground lease or the date of recording
thereof.

     (b) Lessee agrees to execute any documents required to effectuate an
attornment, a subordination, or to make this Lease or any Option granted
hereunder prior to the lien of any mortgage, deed of trust or ground lease, as
the case may be.  Lessee's failure to execute such documents within ten (10)
days after written demand shall constitute a material default by Lessee
hereunder without further notice to Lessee or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact..
Lessee does hereby make,

                                      -26-
<PAGE>

constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
Lessee' name, place and stead, to execute such documents in accordance with this
paragraph 30(b).

Attorneys' Fees.
- ---------------

     If either party or the broker(s) named herein bring an action to enforce
the terms hereof or declare rights hereunder, the prevailing party in such
action, trial or appeal thereon, shall be entitled to his reasonable attorneys'
fees to be paid by the losing party as fixed by the court in the action or a
separate suit, and whether or not such action is pursued to decision or
judgment.  The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

     The attorneys' fee award shall not be computed in accordance with any court
fee schedule, but shall be such as to fully reimburse all attorneys' fees
reasonably incurred in good faith.

     Lessor shall be entitled to reasonable attorneys' fees and all other costs
and expenses incurred in the preparation and service of notice of action and
consultations in connection therewith, whether or not a legal transaction is
subsequently commenced in connection with such default.

Lessor's Access.
- ---------------

     Lessor and Lessor's agents shall have the right to enter the Premises at
reasonable times for the purpose of inspecting the same, performing services
required of Lessor, showing the same to prospective purchasers, lenders, or
lessees, taking such safety measures, erecting such scaffolding or other
necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining
of utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises.  Lessor may at any time place on or about the Premises or the Building
any ordinary "For Sale" signs and Lessor may at any time during the last 120
days of the term hereof place on or about the Premises any ordinary "For Lease"
signs.

unlock all doors in or upon the Premises other than to files, vaults and safes,
and in the case of emergency to enter the Premises by any reasonably appropriate
means, and any such entry shall not be deemed a forceable or unlawful entry or
detainer of

                                      -27-
<PAGE>

the Premises or an eviction. Lessee waives any charges for damages or injuries
or interference with Lessee's property or business in connection therewith.

     1.  Auctions.  Lessee shall not conduct, nor permit to be conducted, either
         --------
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent.  Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent.  The holding of any auction on the Premises or Common Areas in
violation of this paragraph shall constitute a material default of this Lease.

     4.  Signs.  Lessee shall not place any sign upon the Premises or the Office
         -----
Building Project without Lessor's prior written consent.  Under no circumstances
shall Lessee place a sign on any roof of the Office Building Project.

     5.  Merger.  The voluntary or other surrender of this Lease, or a mutual
         ------
cancellation thereof, or a termination by Lessor, shall not work as a merger and
shall, at the option of Lessor, terminate all or any existing subtenancies or
may, at the option of Lessor, operate as an assignment to Lessor of any or all
of such subtenancies.

     6.  Consents.  Except for paragraphs 33 (auctions) and 34 (signs) hereof,
         --------
wherever in this Lease the consent of one party is required to an act of the
other party such consent shall not be unreasonably withheld or delayed.

     7.  Guarantor.  In the event that there is a guarantor of this Lease, said
         ---------
guarantor shall have the same obligations as Lessee under this Lease.

     8.  Quiet Possession.  Upon Lessee paying the rent for the Premises and
         ----------------
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.  The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Office Building Project.

           ----------------
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof, and may
not be exercised or be assigned, voluntarily or involuntarily, by or to any
person or entity other than Lessee; provided, however, that the Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease.  The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from this
Lease in any manner, either by reservation or otherwise.

     39.3  Multiple Options.  In the event that Lessee has any multiple options

     (a) Lessee shall have no right to exercise an Option, notwithstanding any
provision in the grant of Option to the contrary (i) during the time commencing

13.1(c) or 13.1(d) and continuing until the noncompliance outlined in said
notice of default is cured, or (ii) during the period of time commencing on the
day after a monetary obligation to Lessor is due from Lessee and unpaid (without

is paid, or (iii) in the event that Lessor has given to Lessee three or more
notices of default under paragraph 13.1(c), or paragraph 13.1(d), whether or not
the defaults are cured, during the 12 month period of time immediately prior to
the time that Lessee attempts to exercise the subject Option, (iv) if Lessee has
committed any non-curable breach, including without limitation those described
in paragraph 13.1(b), or is otherwise in default of any of the terms, covenants
or conditions of this Lease.

     (b) The period of time within which an Option may be exercised shall not be
extended or enlarged by reason of Lessee's inability to exercise any Option
because of the provisions of paragraph 39.4(a).

and be of no further force or effect, notwithstanding Lessee's due and timely
exercise of the Option, if, after such exercise and during the term of this

Security Measures - Lessor's Reservations.
- -----------------------------------------

     40.1  Lessee hereby acknowledges that Lessor shall have no obligation
whatsoever to provide guard service or other security measures for the benefit
of the Premises or the Office Building Project.  Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties.  Nothing herein contained shall prevent Lessor, at Lessor's sole
discretion, from providing security protection for the Office Building Project
or any part thereof, in which event the cost thereof shall be included within a
definition of Operating Expenses, as set forth in paragraph 4.2(b).

     40.2  Lessor shall have the following rights:

necessary or advisable upon the roof, exterior of the buildings or Office
Building Project or on pole signs in the Common Areas;

     40.3  Lessee shall not:

     (b) Suffer or permit anyone, except in emergency, to go upon the roof of
the Building.

Easements.
- ---------

     41.1  Lessor reserves to itself the right, from time to time, to grant such
easements, rights and dedications that Lessor deems necessary or desirable, and
to cause the recordation of Parcel Maps and restrictions, so long as such
easements, rights, dedications, maps and restrictions do not reasonably
interfere with the use of the Premises by Lessee.  Lessee shall sign any of the
aforementioned documents upon request of Lessor and failure to do so shall
constitute a material default of this Lease by Lessee without the need for
further notice to Lessee.

     41.2  The obstruction of Lessee's view, air, or light by any structure
erected in the vicinity of the Building, whether by Lessor or third parties,
shall in no way affect this Lease or impose any liability upon Lessor.

     Performance Under Protest.  If at any time a dispute shall arise as to any
     -------------------------
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of said party to institute suit for recovery of such payment.  If it shall be
adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

     Authority.  If Lessee is a corporation, trust, or general or limited
     ---------
partnership, Lessee, and each individual executing this Lease on behalf of such,
does hereby represent and warrant that such individual is duly authorized to
execute and deliver this Lease on behalf of said entity.  If Lessee is a
corporation, trust or partnership, Lessee shall, within thirty (30) days after
execution of this Lease, deliver to Lessor evidence of such authority
satisfactory to Lessor.

     Conflict.  Any conflict between the printed provisions, Exhibits or Addenda
     --------
of this Lease and the typewritten or handwritten provisions, if any, shall be
controlled by the typewritten or handwritten provisions.

     Offer.  Preparation of this Lease by Lessor or Lessor's agent and
     -----
submission of same to Lessee shall not be deemed an offer to Lessee to lease.
This Lease shall become binding upon Lessor and Lessee only when fully executed
by both parties.

     Modification.  Lessee agrees to make such reasonable modifications to this
     ------------
Lease as may be reasonably required by an institutional lender in connection
with the obtaining of normal financial or refinancing of the Office Building

the conviction of the Executive of, or the entry of a pleading of guilty or nolo
contendere by the Executive to, any crime involving moral turpitude or any
felony;

         5.3 Immediately upon the death or disability of the Executive. As used
in this Agreement, the term "disability" shall mean the inability of the
Executive, due to a physical or mental disability, for a period of 180 days,
whether or not consecutive, during any 365-day period to perform the services
contemplated under this Agreement. A determination of disability shall be made
by a physician satisfactory to both the Executive and the Company, provided that
                                                                   -------------
if the Executive and the Board of Directors do not agree on a physician, the
Executive and the Company shall each select a physician and these two together
shall select a third physician, whose determination as to disability shall be
binding on all parties;

                                      -4-
<PAGE>

         5.4 At the election of the Executive, upon not less than one hundred
and eighty (180) days' prior written notice to the Company; or

         5.5 At the election of the Company, upon its payment to the Executive
of $200,000.00 for the earlier of (a) a period of 12 months following the
termination date and (b) the balance of the Employment Period.

         6. Effect of Termination. In the event the Executive's employment is
            ---------------------
terminated for any reason, the Company shall pay to the Executive the
compensation and benefits otherwise payable to him under Section 3 through the
last day of the Executive's actual employment by the Company except as may be
provided otherwise under section 5.5. The provisions of Sections 4 shall survive
the termination of this Agreement.

         7. Non-Competition.
            ---------------

         7.1 Executive hereby acknowledges that the Company has developed and
will develop substantial and valuable goodwill with its past, present and future
customers as a result of substantial investments of time, effort and capital.
Executive further acknowledges that he has acquired, and will continue to
acquire, a high level of skill and expertise in the Company's field of business
as a direct result of the Executive's employment by the Company, and that the
Company will likely suffer serious competitive damage if Executive were to
utilize that skill and expertise for the benefit of a competitor of the Company.
Accordingly, Executive hereby covenants and agrees that, during the Employment
Period or any extension thereof and for a period of one (1) year after
termination of his employment by the Company for any reason or no reason, or
from the date of any final judgment upholding the provisions of this Section 7,
whichever is later, Executive shall not, anywhere in North America, Europe and
the Pacific Rim countries, or any other state in which the Company conducts its
business, engage directly, work for or become employed by or associated with any
person or entity, in the same or similar lines of business as the Company.

         7.2 Executive acknowledges that the Company has a place of business,
has employees or representatives, or has advertised or sold products or services
in the restricted geographic region referenced in Section 7.1, thereby
warranting such geographic restriction. The Company and Executive agree that the
duration and geographic scope of the non-competition provisions set forth in
this Section 7 are reasonable. In the event that any court determines that the
duration or the geographic scope, or both, are unreasonable and that either such
provision is to that extent unenforceable, the parties hereto agree that the
provision shall remain in full force and effect for the greatest time period and
in the greatest area that would not render it unenforceable. Executive expressly
grants to the Company for a period of up to one (1) year, as the case may be,
following the termination of this Agreement the right to notify any person at
any time of the terms of this restrictive covenant.

         7.3 The provisions of this Section 7 shall survive any termination of
this Agreement.

         8. Notices. Any notice required or permitted by this Agreement shall be
            -------
given by registered or certified mail, return receipt required, addressed to the
Company at its then principal office, or to the Executive at his address
specified below, or to either party hereto at

                                      -5-
<PAGE>

such other address or addresses as he or it may from time to time specify for
the purpose in a notice similarly given.

         9. Entire Agreement. This Agreement contains the entire agreement of
            ----------------
the parties relating to the subject matter hereof, and there are no agreements,
representations or warranties not herein set forth. No modification of this
Agreement shall be valid unless in writing and signed by the parties hereto. The
waiver or breach of any term or condition of this Agreement shall not be deemed
to constitute a waiver of any subsequent breach of the same or any other term or
condition.

         10. Amendment. This Agreement may be amended or modified only by a
             ---------
written instrument executed by both the Company and the Executive.

         11. Governing Law. This Agreement shall be construed, interpreted and
             -------------
enforced in accordance with the laws of the Commonwealth of Massachusetts.

         12. Successors and Assigns. This Agreement shall extend to and be
             ----------------------
binding upon the Executive, his legal representative or representatives and
testate or intestate distributees, and this Agreement shall extend to and be
binding upon the Company, its successors and assigns. The term "Company" as used
herein shall include such successors and assigns. The term "successors and
assigns" as used herein shall mean a corporation or other entity acquiring all
or substantially all the assets and business of this Company (including this
Agreement) whether by operation of law or otherwise.

         13. Remedies. The rights and remedies of the parties hereunder shall
             --------
not be mutually exclusive, i.e., the exercise of one or more of the provisions
hereof shall not preclude the exercise of any other provisions hereof. Each of
the parties confirms that damages at law will be an inadequate remedy for a
breach or threatened breach of this Agreement and agrees that, in the event of a
breach or threatened breach of any provision hereof, the respective rights and
obligations hereunder shall be enforceable by specific performance, injunction
or other equitable remedy, but nothing herein contained is intended to, nor
shall it, limit or affect any rights at law or by statute or otherwise of any
party aggrieved as against the other for a breach or threatened breach of any
provision hereof, it being the intention by this Section to make clear the
agreement of the parties that the respective rights and obligations of the
parties hereunder shall be enforceable in equity as well as at law or otherwise.
Anything in the contrary notwithstanding, neither party shall seek or be
entitled to punitive damages for any breach alleged of the other and each party
hereby waives his or its right to a jury trial on any matters in dispute under
the Agreement.

         14. Severability. In the event that any section of this Agreement, or
             ------------
any provision of any such section, shall for any reason be held to be wholly
invalid, illegal or unenforceable, such invalidity, illegality or
unenforceability shall not affect any other section hereof, or any other
provisions of any affected section, and this Agreement shall be construed as if,
and enforced as fully as if, such invalid, illegal or unenforceable section or
provisions had never been contained herein. In the event any section, or any
provision thereof, is found to be partially invalid, illegal or unenforceable
(on the ground, for example, that it is excessive in scope), then such section
or

                                      -6-
<PAGE>

provision shall be enforced to the extent not invalid, illegal or unenforceable,
and its partial invalidity, illegality or unenforceability shall not affect any
other section of this Agreement.

         IN WITNESS WHEREOF, the parties hereto have duly executed and delivered
this Agreement under seal as of the day, month and year first above.

     4. Proprietary Information and Developments.
        ----------------------------------------

     4.1  Proprietary Information.
          -----------------------

     (a) Executive agrees that all information and know-how, not in the public
domain or known within the industry, whether or not in writing, of a private,
secret or confidential nature concerning the Company's business, operations,
marketing, research and development or financial affairs (collectively,
"Proprietary Information") is and shall be the exclusive property of the
Company. Executive acknowledges that in the course of his employment, the
Executive will have access to and contact with Proprietary Information. By way
of illustration, but not limitation, Proprietary Information may include
inventions, products, processes, methods, techniques, formulas, compositions,
compounds, projects, developments, plans, research data, clinical data,
financial data, personnel data, computer programs, marketing plans and customer
and supplier lists. Proprietary Information shall also include "Developments"
(as defined below).

     (b) Executive will not disclose any Proprietary Information to others
outside the Company or use the same for any unauthorized purposes without
written approval by the President of the Company, either during or after his or
her employment, unless and until such Proprietary Information has become public
knowledge without fault by the Executive.

     (c) Executive agrees that all files, letters, memoranda, reports, records,
data, sketches, drawings, laboratory notebooks, program listings, or other
written, photographic, electronic or other material containing Proprietary
Information, whether created by the Executive or others, which shall come into
his or her custody or possession, shall be and are the exclusive property of the
Company to be used by the Executive only in the performance of his or her duties
for the Company.

     (d) Executive agrees that the Executive's obligation not to disclose or use
information, know-how and records of the types set forth above, also extends to
such types of information, know-how, records and other property of customers of
the Company or suppliers to


                                     - 2 -
<PAGE>

the Company or other third parties who may have disclosed or entrusted the same
to the Company or to the Executive in the course of the Company's business.

     (e) Upon termination of this Agreement or at any other time upon request by
the Company, Executive shall promptly deliver to the Company all records, files,
memoranda, notes, designs, data, reports, price lists, customer lists, drawings,
plans, computer programs, software, software documentation, sketches, laboratory
and research notebooks and other documents and materials (and all copies or
reproductions of such materials) relating to the business of the Company.

     4.2  Developments.
          ------------

     (a) Executive will make full and prompt disclosure to the Company of all
inventions, improvements, discoveries, methods, developments, software, and
works of authorship, whether or not patentable or copyrightable, which are
created, made, conceived or reduced to practice by the Executive or under the
Executive's direction or jointly with others during the Employment Period,
whether or not during normal working hours or on the premises of the Company
(all of which are collectively referred to in this Agreement as "Developments").

     (b) Executive agrees to assign and does hereby assign to the Company (or
any person or entity designated by the Company) all of his or her right, title
and interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications for no additional
consideration.  However, this Section 4.2(b) shall not apply to Developments
which do not relate to the present or planned business or research and
development of the Company and which are made and conceived by the Executive not
during normal working hours, not on the Company's premises and not using the
Company's tools, devices, equipment or Proprietary Information.

     (c) Notwithstanding the foregoing, copyrightable developments shall be
considered to be "works made for hire" (as such term is defined in the U.S.
Copyright Act), and as such shall be created by the Executive for the exclusive
benefit of the Company.  To the extent that any Development does not qualify as
a "work made for hire," all right, title and interest in and to such
Development, or portion thereof, shall be assigned by the Executive to the
Company for no additional consideration in accordance with the preceding
paragraph.

     (d) Executive agrees to cooperate fully with the Company, both during and
after the Employment Period, with respect to the procurement, maintenance and
enforcement of copyrights, patents and all other intellectual property rights
(both in the United States and foreign countries) relating to Developments.
Executive shall sign all papers, including, without limitation, copyright
applications, patent applications, declarations, oaths, formal assignments,
assignment of priority rights, and powers of attorney, which the Company may
deem necessary or desirable in order to protect its rights and interests in any
Development.

     (e) Executive represents that his or her engagement by the Company and the
performance of his or her duties on behalf of the Company does not, and shall
not, breach any agreement that obligates Executive to keep in confidence any
trade secrets or confidential or proprietary information of any other party or
to refrain from competing, directly or indirectly,


                                     - 3 -
<PAGE>

with the business of any other party. Executive shall not disclose to the
Company any trade secrets or confidential or proprietary information of any
other party.

     (f) Executive acknowledges that the Company from time to time may have
agreements with other persons or with the United States Government, or agencies
thereof, that impose obligations or restrictions on the Company regarding
inventions made during the course of work under such agreements or regarding the
confidential nature of such work.  Executive agrees to be bound by all such
obligations and restrictions and to take all action necessary to discharge the
obligations of the Company under such agreements.

     4.3 Remedies. Executive acknowledges that any breach of the provisions of
         --------
this Section 4 shall result in serious and irreparable injury to the Company for
which the Company cannot be adequately compensated by monetary damages alone.
Executive agrees, therefore, that, in addition to any other remedy it may have,
the Company shall be entitled to enforce the specific performance of this
Agreement by Executive and to seek both temporary and permanent injunctive
relief (to the extent permitted by law) without the necessity of proving actual
damages.

     4.4. Retroactive Confirmation. For the same consideration received upon
          ------------------------
entering into this agreement, Executive hereby confirms that from the time he
first entered the Company's employment, all Developments which he may claim as
attributable to him during that period of employment have been disclosed and
assigned to the Company or may be considered "works for hire" created for the
exclusive benefit of the Company, all as if the provisions of section 4.2,
including without limiting the generality of the foregoing provisions of section
4.2(d), were in full force and effect and binding upon the Executive during that
period of employment.

     5. Employment Termination. The employment of the Executive by the Company
        ----------------------
pursuant to this Agreement shall terminate upon the occurrence of any of the
following:

     5.1 Expiration of the Employment Period unless it is theretofore extended
by mutual written agreement of the parties hereto;

     5.2 At the election of the Company, for cause, immediately upon written
notice by the Company to the Executive. For the purposes of this Section 5.2,
cause for termination shall be upon (a) a good faith finding by the Board of
Directors of the Executive's dishonesty, gross negligence or misconduct, or (b)
the conviction of the Executive of, or the entry of a pleading of guilty or nolo
contendere by the Executive to, any crime involving moral turpitude or any
felony;

     5.3 Immediately upon the death or disability of the Executive. As used in
this Agreement, the term "disability" shall mean the inability of the Executive,
due to a physical or mental disability, for a period of 180 days, whether or not
consecutive, during any 365-day period to perform the services contemplated
under this Agreement. A determination of disability shall be made by a physician
satisfactory to both the Executive and the Company, provided that if the
                                                    -------------
Executive and the Board of Directors do not agree on a physician, the Executive
and the Company shall each select a physician and these two together shall
select a third physician, whose determination as to disability shall be binding
on all parties;


                                     - 4 -
<PAGE>

     5.4 At the election of the Executive, upon not less than one hundred and
eighty (180) days' prior written notice to the Company; or

     5.5 At the election of the Company, upon its payment to the Executive of
$200,000.00 for the earlier of (a) a period of 12 months following the
termination date and (b) the balance of the Employment Period.

     6. Effect of Termination. In the event the Executive's employment is
        ---------------------
terminated for any reason, the Company shall pay to the Executive the
compensation and benefits otherwise payable to him under Section 3 through the
last day of the Executive's actual employment by the Company except as may be
provided otherwise under section 5.5. The provisions of Sections 4 shall survive
the termination of this Agreement.

     7. Non-Competition.
        ---------------

     7.1 Executive hereby acknowledges that the Company has developed and will
develop substantial and valuable goodwill with its past, present and future
customers as a result of substantial investments of time, effort and capital.
Executive further acknowledges that he has acquired, and will continue to
acquire, a high level of skill and expertise in the Company's field of business
as a direct result of the Executive's employment by the Company, and that the
Company will likely suffer serious competitive damage if Executive were to
utilize that skill and expertise for the benefit of a competitor of the Company.
Accordingly, Executive hereby covenants and agrees that, during the Employment
Period or any extension thereof and for a period of one (1) year after
termination of his employment by the Company for any reason or no reason, or
from the date of any final judgment upholding the provisions of this Section 7,
whichever is later, Executive shall not, anywhere in North America, Europe and
the Pacific Rim countries, or any other state in which the Company conducts its
business, engage directly, work for or become employed by or associated with any
person or entity, in the same or similar lines of business as the Company.

     7.2 Executive acknowledges that the Company has a place of business, has
employees or representatives, or has advertised or sold products or services in
the restricted geographic region referenced in Section 7.1, thereby warranting
such geographic restriction. The Company and Executive agree that the duration
and geographic scope of the non-competition provisions set forth in this Section
7 are reasonable. In the event that any court determines that the duration or
the geographic scope, or both, are unreasonable and that either such provision
is to that extent unenforceable, the parties hereto agree that the provision
shall remain in full force and effect for the greatest time period and in the
greatest area that would not render it unenforceable. Executive expressly grants
to the Company for a period of up to one (1) year, as the case may be, following
the termination of this Agreement the right to notify any person at any time of
the terms of this restrictive covenant.

     7.3 The provisions of this Section 7 shall survive any termination of this
Agreement.

     8. Notices. Any notice required or permitted by this Agreement shall be
        -------
given by registered or certified mail, return receipt required, addressed to the
Company at its then principal office, or to the Executive at his address
specified below, or to either party hereto at



                                     - 5 -
<PAGE>

such other address or addresses as he or it may from time to time specify for
the purpose in a notice similarly given.

     9. Entire Agreement. This Agreement contains the entire agreement of the
        ----------------
parties relating to the subject matter hereof, and there are no agreements,
representations or warranties not herein set forth. No modification of this
Agreement shall be valid unless in writing and signed by the parties hereto. The
waiver or breach of any term or condition of this Agreement shall not be deemed
to constitute a waiver of any subsequent breach of the same or any other term or
condition.

     10. Amendment. This Agreement may be amended or modified only by a written
         ---------
instrument executed by both the Company and the Executive.

     11. Governing Law. This Agreement shall be construed, interpreted and
         -------------
enforced in accordance with the laws of the Commonwealth of Massachusetts.

     12. Successors and Assigns. This Agreement shall extend to and be binding
         ----------------------
upon the Executive, his legal representative or representatives and testate or
intestate distributees, and this Agreement shall extend to and be binding upon
the Company, its successors and assigns. The term "Company" as used herein shall
include such successors and assigns. The term "successors and assigns" as used
herein shall mean a corporation or other entity acquiring all or substantially
all the assets and business of this Company (including this Agreement) whether
by operation of law or otherwise.

     13. Remedies. The rights and remedies of the parties hereunder shall not be
         --------
mutually exclusive, i.e., the exercise of one or more of the provisions hereof
shall not preclude the exercise of any other provisions hereof. Each of the
parties confirms that damages at law will be an inadequate remedy for a breach
or threatened breach of this Agreement and agrees that, in the event of a breach
or threatened breach of any provision hereof, the respective rights and
obligations hereunder shall be enforceable by specific performance, injunction
or other equitable remedy, but nothing herein contained is intended to, nor
shall it, limit or affect any rights at law or by statute or otherwise of any
party aggrieved as against the other for a breach or threatened breach of any
provision hereof, it being the intention by this Section to make clear the
agreement of the parties that the respective rights and obligations of the
parties hereunder shall be enforceable in equity as well as at law or otherwise.
Anything in the contrary notwithstanding, neither party shall seek or be
entitled to punitive damages for any breach alleged of the other and each party
hereby waives his or its right to a jury trial on any matters in dispute under
the Agreement.

     14. Severability. In the event that any section of this Agreement, or any
         ------------
provision of any such section, shall for any reason be held to be wholly
invalid, illegal or unenforceable, such invalidity, illegality or
unenforceability shall not affect any other section hereof, or any other
provisions of any affected section, and this Agreement shall be construed as if,
and enforced as fully as if, such invalid, illegal or unenforceable section or
provisions had never been contained herein. In the event any section, or any
provision thereof, is found to be partially invalid, illegal or unenforceable
(on the ground, for example, that it is excessive in scope), then such section
or



                                     - 6 -

provision shall be enforced to the extent not invalid, illegal or unenforceable,
and its partial invalidity, illegality or unenforceability shall not affect any
other section of this Agreement.

     IN WITNESS WHEREOF, the parties hereto have duly executed and delivered
this Agreement under seal as of the day, month and year first above.
