                               PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully, especially the risks of
investing in our common stock discussed under "Risk Factors," before investing
in our common stock.

Our Business

   AverStar is a pioneer in providing information technology, or IT, services
and software products for the mission-critical systems of a significant number
of civilian and defense agencies of the United States government. Our customers
include 16 of the 20 government agencies with the largest IT budgets for the
government's 1999 fiscal year. We also provide our services to large commercial
companies. We have established long-term customer relationships, some of which
have extended over 20 years. During our 30-year history, we have maintained a
strong record of customer satisfaction based on the quality and reliability of
our services and products.

   We provide an integrated offering of services and products in four areas of
IT:

  .  IT Assurance. We provide independent analysis, testing and verification
     of critical information systems under development or being upgraded. We
     also provide security for customers' information systems.

  .  IT Development. We offer a full range of software and systems
     development services for customer-specific applications and Internet
     applications.

  .  IT Operations. We manage and operate information system networks and
     data centers at our customers' facilities.

  .  IT Consulting. We serve as consultants with respect to our customers'
     development of innovative applications or improvements to existing
     critical systems.

   We provide IT assurance services for many of the United States government's
mission-critical systems. An IT system is mission-critical if the failure of
the system would pose a risk to health and safety or cause disruption of a
vital service or function. Our key IT assurance contracts include NASA's space
shuttle, space station and ground systems, the Health Care Finance
Administration's Medicare transactions system and the United States Postal
Service's automation systems. Once a customer retains us to perform assurance
services, we believe that we can gain expertise about the customer's business
and therefore become well positioned to provide additional services and
products to that customer. Since June 1994, more than one-half of our customers
who originally awarded us IT assurance contracts of more than $1.0 million
subsequently awarded us IT development or IT consulting contracts. For example,
after first being engaged to provide IT assurance services, we have been
awarded contracts to provide IT development and IT consulting services to the
United States Postal Service and the Department of Health and Human Services.

   We serve as the prime contractor on a majority of our contracts. Prime
contracts accounted for approximately 78% of our 1998 pro forma revenues. We
believe that our position as prime contractor allows us to develop closer
relationships with our customers, to control the quality of services and
products delivered to the customer and to expand our customer relationships.

Our Market

   The demand for third-party IT services has grown substantially in recent
years. Organizations are increasingly using IT to improve the quality of their
products and services, to reduce their costs and to improve operating
efficiencies. International Data Corporation, or IDC, forecasts that the United
States market for IT services will grow from an estimated $139 billion in 1998
to $207 billion in 2002. IDC forecasts that the IT system services segment of
the worldwide IT services market will grow at a compound annual growth rate of
approximately 12% over this period.

                                       1
<PAGE>


   According to Federal Sources, Inc., the United States government is the
world's largest single buyer of IT services and products. The Electronics
Industry Association, or EIA, reports that the United States government's IT
budget for fiscal 1999 is approximately $30 billion, nearly double the budget
ten years ago. The EIA also estimates that the outsourced portion of the
federal IT budget will be $26 billion in 1999, with approximately 64% allocated
to civilian agencies of the government and 36% allocated to the Department of
Defense.

   We believe that the increasing emphasis by the United States government on
downsizing and reducing budgets will result in the growing use of IT to enhance
productivity and in more testing and upgrading of existing IT systems. In
addition, government agencies are increasingly using commercial procurement
practices. With our position in IT assurance, reputation for quality and
reliability and broad customer base, we believe that we are well positioned to
take advantage of these trends.

Our Corporate History

   Our current business and operations result from a series of strategic
acquisitions of well established IT companies, executed by our current
management team. In February 1998, we combined the businesses of Intermetrics,
Inc. and Pacer Infotec, Inc. Previously, Pacer acquired Infotec Development,
Inc. in July 1996. Founded in 1969, Intermetrics brought us expertise in IT
assurance and IT consulting services for United States civilian and defense
agencies and for commercial organizations and IT development services for
customer-specific applications. Founded in 1968, Pacer broadened our base of
contracts for IT assurance and IT development services for United States
defense and civilian agencies. In March 1999, we acquired Computer Based
Systems, Inc. Founded in 1978, CBSI strengthened our IT operations services and
broadened our customer base among civilian agencies of the federal government.
Our acquisitions have provided us with an experienced management team, a broad
base of long term contracts, a diverse group of established customers,
substantial backlog and strong sales and marketing resources. We believe that
these strengths enable us to compete effectively in our industry.

Our Strategy

   Our goal is to be the leading quality supplier of IT services and software
products for mission-critical systems. To achieve our goal, our strategy is to:

  .  Leverage our position in IT assurance. We intend to continue to
     capitalize on our position in IT assurance to attract new customers and
     to provide additional services and products to our existing customers.

  .  Pursue targeted acquisition opportunities. We seek to acquire companies
     that operate in defined vertical market niches complementary to our
     current business or that have well established relationships with key
     customers.

  .  Expand our commercial business. We intend to leverage our expertise and
     reputation in the federal IT market to compete for commercial projects.

  .  Continue our investment in sales and marketing. We are continuing to
     strengthen our sales and marketing efforts to compete effectively for
     government contracts in a changing procurement environment and to expand
     our commercial customer base.

  .  Maintain our high level of customer satisfaction. We believe that
     maintaining our high level of customer satisfaction and the resulting
     long-term relationships provide a stable customer base from which we can
     grow our business.

   We are incorporated in Delaware. Our principal executive offices are located
at 23 Fourth Avenue, Burlington, Massachusetts 01803. Our telephone number at
that location is (781) 221-6990. Our web site address is www.averstar.com.

                             Summary Financial Data

   The following tables set forth our summary financial data. These tables do
not present all of our financial information. You should read this information
together with our financial statements and the notes to those statements
beginning on page F-1 of this prospectus and the information under "Selected
Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations." On March 13, 1995, an investor group led
by current management formed a holding company that acquired Intermetrics in
August 1995. Substantially all data for the period March 13, 1995 through
February 29, 1996 relate to the operations and financial position of
Intermetrics. The summary financial data for the 12 months ended February 29,
1996, which are unaudited, combine the two preceding columns which reflect the
operations of Intermetrics for the first six months of the period based on
Intermetrics' basis of accounting prior to the acquisition, and our operations
giving effect to the acquisition of Intermetrics in August 1995. In February
1998, we acquired Pacer, whose results of operations are included from the date
of acquisition in our results for the 12 months ended December 31, 1998. In
March 1999, we acquired CBSI. The pro forma column below presents our statement
of operations data as if the acquisitions of Pacer and CBSI had occurred as of
January 1, 1998. The pro forma as adjusted statement of operations data reflect
our sale of shares of common stock in this offering, after deducting
underwriting discounts and estimated offering expenses, and the application of
the proceeds to repay debt as if both these events had occurred as of January
1, 1998. The selected financial data for the 12 months ended February 28, 1997,
the 10 months ended December 31, 1997 and the 12 months ended December 31, 1998
are derived from our audited financial statements included elsewhere in this
prospectus. The selected financial data for the 12 months ended February 28,
1995 are derived from audited financial statements not included in this
prospectus. The consolidated financial data for the three months ended March
31, 1998 and 1999, have been prepared on the same basis as our consolidated
financial statements. In our opinion, all necessary adjustments, consisting of
normal recurring accruals, have been included. Results of operations for
interim periods are not necessarily indicative of results we may achieve in a
full year. Historical results are not necessarily indicative of the results we
may achieve in the future.

   Adjusted EBITDA is net income (loss) from continuing operations before
taxes, interest expense, interest income, depreciation expense, amortization
expense, in process research and development expense and merger-related
expense. Depreciation expense is included in cost of revenues in the following
tables. In process research and development expenses and merger-related
expenses are included in selling, general and administrative expense in the
following tables. Adjusted EBITDA is provided because we believe that investors
may find it to be a useful tool for analyzing our ability to service debt.
Adjusted EBITDA should not be construed:

   .  As an indicator of our operating performance instead of operating income;
or

   .  As a measure of liquidity instead of cash flows from operating
activities.

We may calculate adjusted EBITDA differently than other companies.

                                  RISK FACTORS

   Any investment in our common stock involves a high degree of risk. You
should consider carefully the following information about these risks, together
with the other information contained in this prospectus, before you decide to
buy our common stock. If any of the following risks actually occur, our
business, results of operations and financial condition would likely suffer. In
this case, the market price of our common stock could decline, and you may lose
all or part of the money you paid to buy our common stock.

   Most of our revenues are derived from contracts with agencies of the United
States government, and uncertainties in government contracts could adversely
affect our business.

   Our largest customers are agencies of the United States government. In 1998,
government contracts, and contracts with prime contractors of the United States
government, accounted for approximately 90% of our pro forma revenues. We
believe that United States government contracts are likely to continue to
account for a significant portion of our revenues for the foreseeable future.

   Significant changes in the contracting policies or fiscal policies of the
United States government could adversely affect our business, results of
operations or financial condition.

   Changes in government contracting policies could directly affect our
financial performance. Among the factors that could materially adversely affect
our United States government contracting business are:

  .  Budgetary constraints affecting government spending generally, or
     specific departments or agencies in particular, and changes in fiscal
     policies or available funding;

  .  Cancellation of government programs;

  .  Curtailment of the government's use of technology services firms;

  .  The adoption of new laws or regulations;

  .  Technological developments;

  .  Governmental shutdowns;

  .  Competition and consolidation in the IT industry; and

  .  General economic conditions.

These or other factors could cause governmental agencies to reduce their
purchases under contracts, to exercise their right to terminate contracts or
not to exercise options to renew contracts, any of which could have a material
adverse effect on our business, financial condition or results of operations.

   Many of our United States government customers are subject to increasingly
stringent budgetary constraints. We have substantial contracts in place with
many departments and agencies, and our continued performance under these
contracts, or award of additional contracts from these agencies, could be
materially adversely affected by spending reductions or budget cutbacks at
these agencies. Such reductions or cutbacks could have a material adverse
effect on our business, financial condition or results of operations.

   Our government contracts may be terminated prior to their completion, and we
may not retain these contracts in any competitive rebidding process.

   We derive substantially all of our revenues from government contracts that
typically span one or more base years and one or more option years and are
awarded through formal competitive bidding processes. Many of the option
periods cover more than half of the contract's potential duration. United
States government agencies generally have the right not to exercise these
option periods. In addition, our contracts typically also contain provisions
permitting a government customer to terminate the contract on short notice,
with or without cause. A decision not to exercise option periods or to
terminate contracts would reduce the profitability of these contracts to us.

                                       8
<PAGE>


   Upon expiration, if the customer requires further services of the type
provided in the contract, there is frequently a competitive rebidding process,
and we may not win any particular bid, or be able to replace business lost upon
expiration or completion of a contract. Further, all government contracts are
subject to protest by competitors. The unexpected termination of one or more of
our significant contracts could result in significant revenue shortfalls. The
termination or non-renewal of any of our significant contracts, short-term
revenue shortfalls, the imposition of fines or damages or our suspension or
debarment from bidding on additional contracts could have a material adverse
effect on our business, financial condition or results of operations.

   A negative audit could adversely affect our business, and we could be
required to reimburse the government for costs that we have expended on our
contracts.

   Government agencies routinely audit government contracts. These agencies
review a contractor's performance on its contract, pricing practices, cost
structure and compliance with applicable laws, regulations and standards. Any
costs found to be improperly allocated to a specific contract will not be
reimbursed, while improper costs already reimbursed must be refunded.
Therefore, an audit could result in a substantial adjustment to our revenues.
No material adjustments have resulted from any audits of us completed as of
December 31, 1994, and we believe that adjustments resulting from subsequent
audits will not adversely affect our business. If a government audit uncovers
improper or illegal activities, we may be subject to civil and criminal
penalties and administrative sanctions, including termination of contracts,
forfeitures of profits, suspension of payments, fines and suspension or
debarment from doing business with United States government agencies. In
addition, we could suffer serious reputational harm if allegations of
impropriety were made against us. Any such government determination of
impropriety or illegality, or allegation of impropriety, could have a material
adverse effect on our business, financial condition or results of operations.

   Many of our United States government customers spend their procurement
budgets through General Service Administration Schedule contracts and we are
required to compete for post-award orders.

   Budgetary pressures and reforms in the procurement process have caused many
United States government agencies to increasingly purchase goods and services
through General Service Administration Schedule contracts and other multiple
award and/or government-wide acquisition contract vehicles. We must continually
persuade government agencies to purchase our IT services and products because
government agencies have a larger number of IT service providers from which to
choose under these contracts. We may not maintain or increase revenues or
otherwise sell successfully under these contracts. Our failure to compete
effectively in this procurement environment could have a material adverse
effect on our business, financial condition or results of operations.

   We may be liable for penalties under a variety of procurement rules and
regulations, and changes in government regulations could adversely affect our
business.

   Our defense and commercial businesses must comply with and are affected by
various government regulations. Among the most significant regulations are the
Federal Acquisition Regulations, which comprehensively regulate the formation,
administration and performance of government contracts; the Truth in
Negotiations Act, which requires certification and disclosure of all cost and
pricing data in connection with contract negotiations; the Cost Accounting
Standards, which impose accounting requirements that govern our right to
reimbursement under certain cost-based government contracts; and laws,
regulations and Executive Orders restricting the use and dissemination of
information classified for national security purposes and the exportation of
certain products and technical data. These regulations affect how our customers
and we do business and, in some instances, impose added costs on our
businesses. Any changes in applicable laws could adversely affect the financial
performance of the business affected by the changed regulations. Any failure to
comply with applicable laws could result in contract termination, price or fee
reductions or suspension or debarment from contracting with the United States
government.

If we fail to recruit, train and retain skilled personnel, our costs could
increase and our growth would be limited.

   Our success depends to a significant extent upon our ability to attract,
retain and motivate highly skilled personnel. If we fail to attract, train and
retain sufficient numbers of skilled people, our business, results of
operations or financial condition would suffer. We must continue to hire
skilled people to perform services under our existing contracts and new
contracts that we will enter into. Competition for skilled personnel is intense
in the IT services industry. Recruiting and training skilled personnel require
substantial resources. We also experience significant turnover of skilled
employees. We must pay an increasing amount to hire and retain a skilled
workforce. These factors may create variations and uncertainties in our
compensation expense.

   In addition, our ability to implement our business strategy and to operate
profitably depends largely on the skills, experience and performance of our
management team. If several members of our management team become unable or
unwilling to serve in their present positions, our business, results of
operations or financial condition could suffer.

If we fail to maintain our security clearances, we may not be able to perform
classified work for the government.

   Government contracts require us, and some of our employees, to maintain
security clearances. The loss of these security clearances could curtail the
term and renewal of these government contracts. We maintain facility security
clearances complying with the requirements of the Department of Defense and
other agencies. In addition, approximately 30% of our employees have security
clearances.

We may not successfully execute our acquisition strategy.

   Through acquisitions of companies, we intend to expand our geographic
presence and to expand the products and services we offer to new and existing
customers. If our acquisition strategy fails, we may not continue to grow at
historical rates or at all. We cannot assure you that we will consummate any
acquisitions, or that any acquisitions, if consummated, will be advantageous to
us.

   Various risks may prevent us from completing acquisitions. These risks
include:

  .  Increased competition for acquisitions;

  .  Fewer suitable acquisition candidates available at acceptable prices;

  .  Insufficient capital resources for acquisitions; and

  .  Inability to enter into definitive agreements for desired acquisitions
     on acceptable terms.

   In addition, there are risks that we may not benefit from our acquisitions.
These risks include:

  .  Inability to integrate or operate acquired companies successfully or at
     expected levels of profitability;

  .  Accounting charges that adversely affect our financial results;

  .  Issuance of additional shares of common stock, which could dilute your
     investment; and

  .  Incurrence of additional debt.

If we fail to properly manage our growth, our business could be adversely
affected.

   If we do not manage our growth effectively, our business, results of
operations or financial condition could be materially adversely affected. We
intend to continue the expansion of our operations in the foreseeable future to
pursue existing and potential market opportunities. Our growth places
significant demands on our management and operational resources. In order to
manage our growth effectively, we must continue to invest in our systems of
internal controls and procedures, and continue to expand, train and manage our
workforce.

                                       10

We are highly leveraged.

   We have a substantial amount of indebtedness. If we default on our debt
agreements, our business, financial condition or results of operations would be
materially adversely affected. As of March 31, 1999 we had debt with a face
amount of approximately $59.0 million outstanding. We will repay approximately
$28.7 million of this debt from the proceeds of this offering. We will have
approximately $30.0 million of debt outstanding after this offering. We pay
interest on this debt at variable rates averaging approximately 8.5% per annum.
In addition, we may incur additional debt to finance acquisitions or future
growth.

   Our leverage could have the following important consequences:

  .  Repayment of debt reduces funds available for other purposes;

  .  Our ability to obtain additional debt financing in the future for
     working capital, general corporate purposes or acquisitions may be
     constrained; and

  .  We may be more vulnerable to downturns in general economic conditions or
     our business than our competitors.

We may require additional financing that we may not be able to secure on
favorable terms or at all.

   We may need more financing than currently anticipated to support our growth,
to develop new or enhanced services, to respond to competitive pressures or
unanticipated requirements or to make acquisitions. Any required additional
financing may not be available on terms favorable to us, or at all. If adequate
funds are not available on acceptable terms, we may be unable to fund our
expansion, to develop or enhance services, to respond to competitive pressures
or to take advantage of acquisition opportunities, any of which could have a
material adverse effect on our business, results of operations or financial
condition. If additional funds are raised by our issuing equity securities,
stockholders may experience dilution of their ownership interest and the newly
issued equity securities may have rights superior to those of the common stock.
If additional funds are raised by our issuing debt, we may be subject to
limitations on our operations, including limitations on the payment of
dividends.

Amortization of our intangible assets may have an adverse impact on our
operating results.

   Approximately $35 million, or 37%, of our assets as of March 31, 1999,
consisted of intangible assets, including goodwill, arising from our
acquisitions. This amount will be amortized over 18 months to 20 years. This
non-cash expense, some of which is not tax deductible, will reduce net income
or increase net loss in each amortization period. This reduction in our net
income or increase in our net loss may have an adverse effect on the market
price of our common stock.

   In addition, we may never realize the value of our intangible assets. We
evaluate current events and circumstances to determine whether the remaining
balance of our intangible assets will be recoverable. If we deem all or part of
our intangible assets to be not recoverable, we would reduce the carrying value
of our intangible assets, which could have a material adverse effect on our
operating results for the period in which the reduction is recognized.

We may not be able to compete successfully.

   Our business could suffer if we are not able to compete successfully. We
experience significant competition in all areas of our business. In general,
the markets in which we compete are not dominated by a single company or a
small number of companies. Thousands of companies offer services and products
that are competitive with our IT service and product offerings. However, we
compete regularly with approximately seven different competitors in our IT
assurance service offerings, 18 in our IT development service offerings, six in
our IT operations service offerings and four in our IT consulting service
offerings.

                                       11
<PAGE>


Many of our competitors are significantly larger and have greater financial
resources than we do. In addition, many of our competitors have significantly
more experience in the commercial IT market than we have. These factors may
place us at a disadvantage in responding to competition, technological changes
and changes in customer requirements. In addition, some of the contracts on
which we have the technical capability to bid are set aside for companies which
the United States government classifies as "small businesses" or "minority
businesses." After 1999, we will not qualify for any of these classifications.

The pricing provisions of our contracts may adversely affect our profits.

   Some of our contracts are fixed-price contracts which contain pricing
provisions that require the payment of a set price by the customer for our
services regardless of the costs we incur in performing these services, or
provide for penalties in the event we fail to achieve contract requirements.
Failure to anticipate technical problems, estimate costs accurately or control
costs during our performance of a fixed-price contract may reduce our profit or
cause us to suffer a loss. The number of our fixed-price contracts may increase
as our commercial business increases.

   Recently, a growing percentage of our contracts are time-and-materials
contracts. Typically, time-and-materials contracts provide for the customer to
pay a specified rate per hour of labor dedicated to the project. If market or
other conditions require us to increase our employees' salaries or other costs
and we cannot convince our customers to pay proportionately higher prices, we
would suffer reduced profits or losses under these contracts.

Fluctuations in our operating results may negatively impact our stock price.

   The price of our common stock may fall because of fluctuations in our
quarterly operating results and our inability to meet market expectations. Our
operating results may fluctuate significantly in the future due to a variety of
factors that could affect our revenues or our expenses in any particular
quarter. Factors that may affect our quarterly results include, but are not
limited to:

  .  The number, size and scope of projects;

  .  Our expenditures;

  .  The accuracy of our estimates of resources required to complete ongoing
     projects;

  .  The demand for our services and products; and

  .  The adequacy of our reserves for losses.

   Accordingly, we believe that quarter-to-quarter comparisons of operating
results are not necessarily meaningful. You should not rely on the results of
any one quarter as an indication of our results for a full year or any other
quarter.

We may not realize all of the revenues included in our backlog.

   Although our contract backlog was approximately $450 million as of March 31,
1999, we may not realize all of this backlog as revenue. Backlog represents
management's estimate of our realizable revenues on our contracts. Please see
"Business--Backlog." Government contracts comprise substantially all of our
backlog. The following factors may affect our ability to realize revenues
included in our backlog:

  .  The government's failure to fund all of the years of a multi-year
     contract;

  .  The government's failure to exercise its option to extend the length of
     a contract;

  .  The government's failure to request any services under contracts that we
     provide only upon request of the government; and

  .  The government's decision to decrease the size or scope of a contract.

                                       12

We may not be able to replace our Year 2000 testing and assessment contracts
with equally profitable business.

   As demand for Year 2000 services declines, unless we are able to replace our
Year 2000 business with equally profitable work, our rate of revenue growth and
our profits could suffer. In 1998, approximately 6% of our pro forma revenues
related to Year 2000 testing and assessment services.

We may not be successful in expanding our commercial business.

   Only a small portion of our business is currently derived from the
commercial IT market. If we are not able to increase the amount of services and
products we sell to the commercial market, we may not grow at expected rates
and our reliance on federal government agencies may continue.

Changes in technology could adversely affect our business.

   Our business could suffer if we are not successful in adopting and
integrating new technologies into our service and product offerings in a timely
and cost-effective manner. The markets for our IT services and products change
rapidly because of technological innovations, new product introductions,
changes in customer requirements, declining prices and evolving industry
standards, among other factors. New products and new technology often render
existing information services or technology infrastructure obsolete. As a
result, our success depends on our ability to integrate new technologies into
our service offerings.

   Further, we cannot be sure that we will be able to continue to commit the
resources necessary to refresh our technology infrastructure at the rate
demanded by our markets. Advances in technology require us to commit
substantial resources to acquire and deploy new technologies for use in our
operations. We must continue to commit resources to train our personnel in the
use of these new technologies. We must also continue to maintain the
compatibility of existing hardware and software systems with these new
technologies.

We may be unable to protect our intellectual property rights, and we may be
liable for infringing the intellectual property rights of others.

   Third parties may infringe or misappropriate our patents, trademarks or
other proprietary rights, which could have a material adverse effect on our
business, results of operations or financial condition. The steps we have taken
to protect our proprietary rights may not prevent misappropriation. Our
suppliers, customers and competitors may have patents and other proprietary
rights that cover technology utilized by us. These persons may also seek
patents in the future. United States patent applications are confidential until
a patent is issued, and most technologies are developed in secret. Accordingly,
we are not aware of all patents or other intellectual property rights that our
services and products may infringe.

   We could incur substantial costs to prosecute or defend any litigation
against others who allege infringement of intellectual property rights.
Intellectual property litigation could force us to do one or more of the
following:

  .  Cease selling or using services or products that incorporate infringed
     intellectual property;

  .  Obtain from the holder of the infringed intellectual property right a
     license to sell or use the relevant technology; and

  .  Redesign those services or products that incorporate infringed
     intellectual property.

Our shares may experience extreme price and volume fluctuations.

   Just as the shares of other IT companies have experienced price and volume
fluctuations, the market price of our common stock may be volatile. You may not
be able to resell your shares at or above the initial public offering price and
may suffer a loss of your investment.


                                       13
<PAGE>

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

  .  Quarterly variations in operating results;

  .  Changes in financial estimates by securities analysts;

  .  Changes in market valuations of IT service companies;

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

  .  Losses of major contracts;

  .  Additions or departures of key personnel; and

  .  Sales of common stock by our stockholders.

   In the past, securities class action litigation has often been initiated
against a company following periods of volatility in the market price of their
securities. If a suit is initiated against us, regardless of the outcome, it
could result in substantial costs, diversion of our management's attention and
resources, and a material adverse effect on our business, results of operations
or financial condition.

Future sales of large amounts of our stock, or the perception that such sales
could occur, may adversely affect our stock price.

   The market price of our common stock could drop as a result of sales of a
large number of shares of common stock in the market after this offering, or
the perception that such sales could occur. Assuming no exercise of the
underwriters' over-allotment option, there will be 10,880,655 shares of common
stock outstanding immediately after this offering. The 4,000,000 shares of
common stock sold in this offering will be freely tradeable without restriction
or further registration under the Securities Act of 1933, unless such shares
are held by our "affiliates," as that term is defined in Rule 144 under the
Securities Act. As of March 1, 2000, holders of approximately 5,254,977 shares
of our common stock will be able to sell their shares without limitation under
Rule 144(k). After this offering, we will have 3,349,447 shares of common stock
reserved for issuance upon the exercise of stock options, of which 1,513,433
shares are subject to currently outstanding options. Following this offering,
we intend to file registration statements on Form S-8 to register these shares.
Please see "Shares Eligible for Future Sale."

Provisions of our certificate of incorporation and bylaws and Delaware law
could deter takeover attempts.

   Some provisions in our certificate of incorporation and bylaws could delay,
defer, prevent or make more difficult a merger, tender offer or proxy contest
involving our company. However, our stockholders might view such a transaction
as being in their best interests because, for example, a change of control
might result in a price higher than the market price for shares of our common
stock. Among other things, these provisions:

  .  Require an 80% vote of the stockholders to amend certain provisions of
     our certificate of incorporation and by-laws;

  .  Permit only our chairman, president or a majority of the board of
     directors to call stockholder meetings;

  .  Authorize our board of directors to issue shares of preferred stock in
     series with the terms of each series to be fixed by our board of
     directors without any further action by our stockholders;

  .  Divide our board of directors into three classes so that only
     approximately one-third of the total number of directors will be elected
     each year; and

  .  Specify advance notice requirements for stockholder proposals and
     director nominations to be considered at a meeting of stockholders.

                                       14
<PAGE>

   In addition, with certain exceptions, Section 203 of the Delaware General
Corporation Law restricts certain mergers and other business combinations
between us and any holder of 15% or more of our voting stock.

Potential Year 2000 problems could adversely affect our business.

   We believe that it is not possible to determine with complete certainty that
all Year 2000 problems affecting us or our customers have been identified or
corrected. As a result, we believe that the following consequences are
possible:

  .  Operational inconveniences and inefficiencies for us and our customers
     may divert management's time and attention and financial and human
     resources from ordinary business activities;

  .  Routine business disputes and claims for pricing adjustments or
     penalties due to Year 2000 problems may occur, which will be resolved in
     the ordinary course of business;

  .  Serious system failures may require significant efforts by us or our
     customers to prevent or alleviate material business disruptions; and

  .  Serious business disputes alleging that we failed to comply with the
     terms of contracts or industry standards of performance may result in
     litigation or contract termination.

   In addition, any system failures could interfere with our ability to
properly manage contracted projects and could adversely affect our business.


You will suffer immediate and substantial dilution.

   Investors purchasing shares in this offering will suffer immediate and
substantial dilution of their investment, because the initial public offering
price per share will significantly exceed the net tangible book value per
share.

                           FORWARD-LOOKING STATEMENTS

   Many statements made in this prospectus under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere are forward-
looking statements. In some cases, you can identify forward-looking statements
by terminology such as "may," "will," "should," "expects," "plans,"
"anticipates," "believes," "estimates," "predicts" or "continue" or the
negative of these terms or other comparable terminology. Forward-looking
statements are speculative and uncertain and not based on historical facts.
Because forward-looking statements involve risks and uncertainties, there are
important factors that could cause actual results to differ materially from
those expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors." Although we believe that the expectations
reflected in the forward-looking statements are reasonable, we cannot guarantee
future results, performance or achievements. Moreover, neither we nor any other
person assumes responsibility for the accuracy and completeness of these
forward-looking statements. We are under no duty to update any of the forward-
looking statements after the date of this prospectus to conform such statements
to actual results.

                                USE OF PROCEEDS

   Our net proceeds from the sale of the shares offered by us in this offering
are estimated to be approximately $28.7 million, or approximately $33.1 million
if the underwriters' over-allotment option is exercised in full, assuming an
initial public offering price of $8.00 per share and after deducting
underwriting discounts and estimated offering expenses payable by us.

   We intend to use these net proceeds as follows:

  .  To repay $23.7 million of the amount outstanding as of March 31, 1999
     under our credit agreement with First Union Commercial Corporation, as
     agent, and the other lenders that are parties to our credit agreement;
     and

  .  To repay subordinated debt outstanding with a face value of $5.0 million
     as of March 31, 1999 under our subordinated debt agreement with
     MassMutual.

   As of March 31, 1999, approximately $53.4 million was outstanding under our
credit agreement with First Union. We used approximately $25.0 million to
acquire CBSI, $24.0 million to repay existing debt and $5.0 million to pay
transaction fees and expenses and to fund general working capital requirements.
Our credit agreement with First Union expires in 2004 and March 2005. Loans
outstanding at March 31, 1999 under our credit agreement with First Union bear
interest at variable rates averaging approximately 8% per year.

   In connection with the acquisition of Intermetrics by an investor group led
by our current management, we obtained a credit facility with Massachusetts
Mutual Life Insurance Company, or MassMutual, and affiliates of MassMutual in
August 1995. As of March 31, 1999, subordinated debt with a face value of $5.0
million was outstanding under our credit agreement with MassMutual. The loan
outstanding under our credit agreement with MassMutual bears interest at a rate
of 13% per year. This credit agreement expires in June 2005.

                                DIVIDEND POLICY

   We intend to retain all future earnings, if any, to finance the expansion of
our business. We have not declared or paid any cash dividends on our common
stock since our inception and do not expect to declare or pay any cash
dividends in the foreseeable future. In addition, our credit agreement with
First Union contains restrictions on our ability to pay dividends.

                                 CAPITALIZATION

   The following table sets forth, as of March 31, 1999, our capitalization:

  .  On an actual basis; and

  .  On an as adjusted basis to give effect to our sale of 4,000,000 shares
     in this offering, assuming an initial public offering price of $8.00 per
     share and after deducting underwriting discounts and the estimated
     offering costs payable by us, and the application of the proceeds to
     repay debt.

This information should be read together with our financial statements and the
notes relating to those statements appearing elsewhere in this prospectus.

   The table below does not reflect the following changes to our capitalization
since March 31, 1999:

  .  We issued 37,500 shares to the AverStar Profit Sharing & Savings Plan;

  .  We redeemed 84,870 shares from stockholders under the terms of existing
     agreements for an aggregate of approximately $410,000; and

  .  At the closing of this offering, we will issue approximately 911 shares
     from treasury to stockholders pursuant to obligations incurred in
     connection with the acquisition of Intermetrics.

                                    DILUTION

   Our net tangible book value as of March 31, 1999 was $(31,008,000), or
$(4.48) per share. Our net tangible book value per share is equal to the amount
of our total tangible assets less total liabilities, divided by the number of
shares of common stock outstanding as of March 31, 1999. Assuming that we sell
the 4,000,000 shares offered by us in this offering at an initial public
offering price of $8.00 per share, after deducting the underwriting discounts
and the estimated offering expenses payable by us, and apply the proceeds to
repay debt, our pro forma net tangible book value as of March 31, 1999 would
have been $(2,591,000),
or $(0.24) per share. This amount represents an immediate increase in pro forma
net tangible book value of $4.24 per share to existing stockholders and an
immediate dilution in pro forma net tangible book value of $8.24 per share to
investors purchasing shares in this offering. The following table illustrates
this per share dilution:

   None of the foregoing tables or calculations assumes that any options
outstanding as of March 31, 1999 will be exercised. If all outstanding options
were exercised on the date of the closing of this offering, new investors
purchasing shares in this offering would suffer total dilution of $8.16 per
share.

   The above tables do not reflect the following changes to our capitalization
since March 31, 1999:

  .  We issued 37,500 shares to the Averstar Profit Sharing & Savings Plan;

  .  We redeemed 84,870 shares from stockholders under the terms of existing
     agreements for an aggregate of approximately $410,000; and

  .  At the closing of this offering, we will issue approximately 911 shares
     from treasury to stockholders pursuant to obligations incurred in
     connection with the acquisition of Intermetrics.

                            SELECTED FINANCIAL DATA

   The following tables set forth our selected financial data. These tables do
not present all of our financial information. You should read this information
together with our financial statements and the notes to those statements
beginning on page F-1 of this prospectus and the information under
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." On March 13, 1995, an investor group formed a holding company
which acquired Intermetrics in August 1995. Substantially all data for the
period March 13, 1995 through February 29, 1996 relate to the operations and
financial position of Intermetrics. The selected financial data for the 12
months ended February 29, 1996, which are unaudited, combine the two preceding
columns which reflect the operations of Intermetrics for the first six months
of the period based on Intermetrics' basis of accounting prior to the
acquisition, and our operations giving effect to the acquisition of
Intermetrics in August 1995. In February 1998, we acquired Pacer, whose results
of operations are included from the date of acquisition in our results for the
12 months ended December 31, 1998. In March 1999, we acquired CBSI. The pro
forma column presents our statement of operations data as if the acquisitions
of Pacer and CBSI had occurred as of January 1, 1998. The pro forma as adjusted
statement of operations data reflect our sale of shares of common stock in this
offering, after deducting underwriting discounts and estimated offering
expenses, and the application of the proceeds to repay debt as if both these
events had occurred as of January 1, 1998. The selected financial data for the
12 months ended February 28, 1997, the 10 months ended December 31, 1997 and
the 12 months ended December 31, 1998 are derived from our audited financial
statements included elsewhere in this prospectus. The selected financial data
for the 12 months ended February 28, 1995 are derived from audited financial
statements not included in this prospectus. The consolidated financial data for
the three months ended March 31, 1998 and 1999 have been prepared on the same
basis as our consolidated financial statements. In our opinion, all necessary
adjustments, consisting of normal recurring accruals, have been included.
Results of operations for interim periods are not necessarily indicative of
results we may achieve in a full year.

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

   The following discussion of our financial condition and results of
operations should be read together with the financial statements and the notes
to those statements included elsewhere in this prospectus. This discussion
contains forward-looking statements that involve risks and uncertainties.
Please see "Risk Factors" and "Forward-Looking Statements."

Overview

   We provide IT services and products to the United States government and to
commercial companies. Through both internal growth and a series of
acquisitions, we have increased our revenues from $53.3 million for the fiscal
period ended February 28, 1997 to $169 million in pro forma revenues for the
fiscal period ended December 31, 1998. Our growth has resulted in a broader
base of long-term contracts and a more diverse group of established customers.

   AverStar is the result of a series of strategic acquisitions executed by our
current management. In February 1998, we combined the businesses of
Intermetrics and Pacer. In March 1999, we acquired CBSI for $26 million in
cash, $25 million of which was paid to the former CBSI stockholders at the
closing and $1 million of which will be paid ratably over the next five years.
All three transactions were accounted for as purchases. During 1997, we changed
our fiscal year to a December 31 year end in anticipation of the merger with
Pacer. As a result, the fiscal period ended December 31, 1997 is a ten-month
period.

   A substantial portion of our revenues are derived from contracts with the
United States government. Approximately 90% of our pro forma revenues in the
fiscal period ended December 31, 1998 were derived from government contracts,
either directly with government customers or indirectly through government
prime contractors.

   We enter into three types of contracts: cost-reimbursable, time-and-
materials, and fixed-price contracts. Of our total pro forma revenues for 1998,
cost-reimbursable contracts represented approximately 46%, time-and-materials
contracts approximately 45% and fixed-price contracts approximately 9%. Cost-
reimbursable contracts provide for the reimbursement of costs plus the payment
of a fixed fee. Under time-and-materials contracts, we are reimbursed for labor
hours at negotiated hourly billing rates and reimbursed for travel and other
direct expenses at actual cost plus applied indirect, general and
administrative expenses. Under fixed-price contracts, we agree to perform
certain work for a fixed price and, accordingly, realize a benefit or detriment
to the extent that our actual cost of performing the work differs from the
negotiated price.

   We assume greater financial risk on fixed-price contracts than on either
time-and-materials or cost-reimbursable contracts. We believe that an
increasing percentage of our contracts will be fixed-price as our commercial
business increases. Failure to anticipate technical problems, estimate costs
accurately or control costs during performance of a fixed-price contract may
reduce our profits or cause us to suffer a loss. If we are successful in
providing our services at a reduced cost, however, we expect that fixed-price
contracts will result in greater profitability. In addition, greater risks are
involved under time-and-materials contracts than under cost-reimbursement
contracts because we assume the responsibility for the delivery of specified
skills at a fixed hourly rate. Our management believes that adequate reserves
for our fixed-price and time-and-materials contracts are reflected in our
financial statements.

   We recognize revenues on government and commercial contracts under the
percentage-of-completion method. This method involves a periodic assessment of
the estimated total cost to complete each contract. The percentage-of-
completion method is determined by relating the actual costs incurred to date
to the estimated total costs at completion. The cumulative effects resulting
from revisions of estimated total costs and revenues are recorded in the period
in which the facts requiring revisions become known. When a loss is anticipated
on a contract, the full amount of the anticipated loss is provided for at that
time.

   Revenues from standard software products are recognized upon shipment in
accordance with Statement of Position 97-2, "Software Revenue Recognition."
Revenues from maintenance agreements are deferred and amortized over the life
of the maintenance agreements. Our royalty income is derived from licensing
agreements that we have with commercial companies. Typically, the amount of our
royalty income is based on a percentage of our customer's revenues for the
products that incorporate our technology. Per unit royalties earned from the
license of standard software products are recognized when received from the
customer. Our royalty income does not represent a significant portion of our
revenues.

 Three-Month Periods Ended March 31, 1998 and 1999

   The results of operations for the three months ended March 31, 1998 reflect
the activity of Intermetrics for the entire three months of the quarter and the
activity of Pacer for one month of the quarter. The results of operations for
the three months ended March 31, 1999 reflect the activity of Intermetrics and
Pacer for the entire three months of the quarter and ten days of activity of
CBSI.

   Revenues. For the three months ended March 31, 1999, our revenues were $36.3
million compared to $22.7 million for the three months ended March 31, 1998. Of
the $13.6 million or 60% increase, approximately $8.6 million or 63% related to
the acquisition of Pacer and approximately $950,000 or 7% related to the
acquisition of CBSI. The remaining 30% of the increase was associated with new
task orders and additional work performed under existing contracts, mainly with
the United States Postal Service, Government Services Agency Schedule or GSA,
National Institutes of Health and NASA.

   Cost of revenues. For the three months ended March 31, 1999, our cost of
revenues was $28.8 million compared to $17.3 million for the three months ended
March 31, 1998, an increase of $11.5 million or 67%. As a percentage of
revenues, cost of revenues was 79.3% for the period ended March 31, 1999 and
76.1% for

                                       24
<PAGE>


the period ended March 31, 1998. The increase in cost of revenues as a
percentage of revenues resulted from higher costs in relation to revenues from
acquired contracts and less than full utilization of office facilities acquired
to support the increase in the number of contracts and task orders performed.

   Selling, general and administrative expense. For the three months ended
March 31, 1999, our selling, general and administrative, or SG&A, expense,
including amortization expense, was $5.3 million compared to $4.2 million for
the first quarter of 1998, an increase of $1.1 million or 27%. Amortization
expense was $300,000 of the $5.3 million in 1999 and $100,000 of the $4.2
million in 1998. The $200,000 increase in amortization expense reflects three
months amortization related to Pacer in 1999 and ten days related to CBSI
compared with one month and none, respectively, in the 1998 first quarter
results. Of the remaining $900,000 increase in total SG&A expense,
approximately 50% was associated with the increased staff from Pacer,
approximately 22% related to the growth in the sales and marketing function and
the remainder related to acquisition and financing activities. As a percentage
of revenues, SG&A expense decreased to 14.6% in the first quarter 1999 from
18.3% in the first quarter 1998, primarily because SG&A expense was spread over
a larger revenue base in 1999.

   Income from continuing operations. For the three months ended March 31,
1999, our income from continuing operations before interest and taxes was $2.2
million compared with $1.3 million for the three months ended March 31, 1998,
representing a $900,000 or 75% increase. Approximately $500,000 or 53% of this
increase was attributable to the acquisition of Pacer and about 5% was
attributable to the acquisition of CBSI. The remainder of the increase resulted
from increased profit recorded on new and additional work performed.

   Net income from continuing operations. For the three months ended March 31,
1999, net income from continuing operations was $800,000 compared to $400,000
in 1998, an increase of 100%. The increase resulted from higher operating
income of $900,000 reduced by an increase in interest expense of $300,000 and an
increase in income taxes of $200,000. The increase in interest expense resulted
from additional borrowings to fund the acquisition of CBSI and to support
working capital requirements. The increase in taxes was caused by the increase
in taxable income.

   Net income. For the three months ended March 31, 1999, our net income was
$800,000 compared to a net loss of $200,000 for the first quarter of 1998. The
net loss for 1998 was the result of income from continuing operations of
$400,000 offset by a net loss from discontinued operations of $600,000.

 Fiscal Periods Ended February 28, 1997, December 31, 1997 and December 31,
1998

   Revenues. For the 12 months ended December 31, 1998, our revenues were
$121.1 million compared to $53.6 million for the ten months ended December 31,
1997 and $53.3 million for the 12 months ended February 28, 1997, representing
a 127% increase over this period. Of the approximately $68 million increase in
revenues over this period, approximately $39 million, or 57% of the increase,
was the result of the acquisition of Pacer which became effective February 27,
1998. Approximately $12 million, or 18% of the increase, resulted from our
winning two contracts with the United States Postal Service in mid-1997. We
benefitted from the first full-year effect of these contracts in 1998. The
increased work under a contract awarded by NASA in 1996 accounted for
approximately $9 million, or 13% of the increase. Revenues were also positively
affected by increased business with commercial customers, by new contracts with
the National Institute of Health and the United States Navy and by increased
royalty income.

   Cost of revenues. For the 12 months ended December 31, 1998, our cost of
revenues was $93.6 million compared to $41.7 million for the ten months ended
December 31, 1997 and $40.7 million for the 12 months ended February 28, 1997,
representing a 130% increase over this period. The increase primarily resulted
from higher labor costs to support a larger number of contracts. As a
percentage of revenues, cost of revenues has not changed significantly: 77.3%
for the period ended December 31, 1998, 77.7% for the period ended December 31,
1997 and 76.4% for the period ended February 28, 1997.

                                       25
<PAGE>


   Selling, general and administrative expense. For the 12 months ended
December 31, 1998, our selling, general and administrative expense, including
amortization expense, was $20.6 million compared to $10.4 million for the ten
months ended December 31, 1997, and $11.2 million for the 12 months ended
February 28, 1997, representing an increase of $9.4 million, or 84%, over this
period. This increase is attributed to increased staff related to the
acquisition of Pacer, increased sales and marketing staff and $1.5 million of
expenditures related to the consolidation of Pacer. The decrease of $800,000
from the 12-month period ended February 28, 1997 to the ten-month period ended
December 31, 1997 was primarily due to the ten-month reporting period. As a
percentage of revenues, SG&A expense decreased to 17% in the 12 months ended
December 31, 1998, from 19% in the ten months ended December 31, 1997 and from
21% in the 12 months ended February 28, 1997, primarily because SG&A expense
was spread over a larger revenue base in 1998.

   Income from operations. For the 12 months ended December 31, 1998, our
income from operations was $6.9 million compared to $1.6 million for the ten
months ended December 31, 1997 and $1.3 million for the 12 months ended
February 28, 1997, representing a 431% increase over this period. Of the $5.6
million increase in income from operations over this period, approximately $1.9
million, or 34% of the increase, is attributable to the acquisition of Pacer.
Approximately $1.8 million of the increase, or 32%, was the result of higher
royalty revenues.

   Net income from continuing operations. For the 12 months ended December 31,
1998, net income from continuing operations was $2.4 million compared to
$198,000 for the ten months ended December 31, 1997 and $27,000 for the 12
months ended February 28, 1997. The increase in net income from continuing
operations of $2.4 million over this period resulted from the increase in
income from operations of $5.5 million offset by a $1.0 million net increase in
interest expense and an increase in taxes of $2.2 million. The increase in
interest resulted from additional borrowing to partially fund the acquisition
of Pacer and to support working capital needs. The increase in taxes resulted
from the increased operating income.

   Net income. For the 12 months ended December 31, 1998, our net loss was $2.7
million, compared to a net loss of $1.5 million for the ten months ended
December 31, 1997 and net income of $27,000 for the 12 months ended February
28, 1997. The net loss for 1998 resulted from income from continuing operations
of $2.4 million offset by a net loss from the discontinued operations of $2.5
million and by a net loss on the disposal of discontinued operations of $2.6
million. Similarly, the net loss for the ten months ended December 31, 1997 was
the result of income from continuing operations of $198,000 and a net loss from
discontinued operations of $1.7 million. There was no loss from discontinued
operations for the 12 months ended February 28, 1997.

Liquidity and Capital Resources

   In March 1999, we refinanced our outstanding debt in conjunction with the
purchase of CBSI. We obtained a $75.0 million credit facility from a group of
lenders led by First Union Commercial Corporation. This facility comprised
$45.0 million in senior debt and $30.0 million in revolving credit. In
addition, we maintain a $5.0 million subordinated debt agreement, which we
obtained in August 1995, with MassMutual. Our total debt capacity has a face
value of $80 million. At March 31, 1999, our outstanding debt under these
agreements was approximately $58.4 million. The availability of approximately
$21.3 million under the revolving credit agreement is subject to certain
covenants and collateral limitations. At March 31, 1999, about $10.0 million of
additional borrowing under the revolving credit facility was available to us
based on the covenants and limitations. Our First Union Credit Facility is
secured by the stock of our subsidiaries, our accounts receivable and
substantially all our other assets. The agreements expire in March 2004 and
March 2005. Loans outstanding under these agreements bear interest at variable
rates generally based on LIBOR approximating 8.5% per year.

   Our current credit agreements require that at least 50% of the proceeds of a
sale of equity be used to reduce debt under the agreements. We expect to apply
$28.7 million to reduce the senior and subordinated debt under our current
agreements thereby increasing the amount of our borrowing capacity. Please see
"Use of

                                       26
<PAGE>


Proceeds." As of March 31, 1999, after giving effect to this offering and the
application of the proceeds to repay debt, approximately $21.0 million would be
outstanding in senior debt, $0 in subordinated debt, and approximately $8.7
million in revolving credit. We intend to seek to increase the borrowing
capacity under our revolving credit facility from a group of lenders led by
First Union after this offering, primarily to fund acquisitions.

   We believe the capital resources available to us under our credit agreements
and cash from our operations are adequate to fund our ongoing operations and to
support the internal growth we expect to achieve for at least the next 12
months. In the longer term, we anticipate financing our internal and external
growth from acquisitions through one or a combination of the following: cash
from operations; additional borrowing; issuance of equity; use of the existing
revolver facility; or a refinancing of our credit facilities. Please see "Risk
Factors--We may require additional financing that we may not be able to secure
on favorable terms or at all."

Backlog

   Backlog represents management's estimate of our aggregate realizable
revenues over the term of all of our contracts, including any option periods.
However, backlog is not necessarily indicative of future revenues. Our contract
backlog was approximately $450 million as of March 31, 1999. Our backlog is
composed of:

  .  Customer authorized contract values for which the customer has set
     aside, appropriated or committed funds for specifically identified
     services, products, tasks or delivery orders; and

  .  Management's estimate of the realizable contract values for all expected
     future services, products, tasks or delivery orders, for which funds
     have not yet been set aside, appropriated or committed.

   The actual timing of our receipt of revenues, if any, on projects included
in our backlog could change because many factors affect the scheduling of
projects. In addition, cancellations or adjustments to contracts may occur. Our
backlog is subject to large variations from quarter to quarter as existing
contracts are renewed or new contracts are awarded. Additionally, virtually all
of our backlog represents contracts with the United States government which may
be terminated at any time for any reason.

Discontinued Operations

   In August 1997, we combined our computer and video game business with the
operations of Looking Glass Technologies, Inc. to form Intermetrics
Entertainment Software, LLC, or IES. After the combination, we owned 66% of IES
and consolidated the results of IES' operations with our operations for our
financial reporting purposes. In December 1998, we approved a plan of
divestiture of IES by means of a distribution of our interest in IES to our
stockholders. We effected the distribution in March 1999. Please see note 3 to
our consolidated financial statements. As part of our plan of divestiture, we
structured financial arrangements with IES that included the conversion of $1.3
million of capital contributed to IES into a term loan, and the establishment
of a $2.0 million revolving credit facility for use by IES through December 31,
1999. The term loan is equal to our capital contributed to IES, reduced by the
operating losses of IES during our ownership period. We converted the
contributed capital to a term loan because the term loan provides us with the
possibility to recover some of the advances we made to IES without creating
adverse tax consequences. The revolving credit facility obligates us to advance
up to $2.0 million to IES through December 31, 1999. These advances must be
made available at any time, for any amount up to $2.0 million, as long as IES
has not filed for bankruptcy and is not in the process of liquidation or the
equivalent. Amounts advanced under the term loan and revolving credit facility
and an additional $400,000 in term loans mature on December 31, 2001. If not
prepaid, we will pursue collection of all amounts due. However, we presently do
not believe that we will be successful in our collection efforts.

   As a result of the plan of divestiture approved by us in December 1998 and
completed in March 1999, we have accounted for our investment in IES as a
discontinued operation in 1997 and 1998. For the five months

                                       27
<PAGE>


ended December 31, 1997, IES recorded revenues of $1.9 million and a net loss
from operations of $1.7 million. For the twelve months ended December 31, 1998,
IES recorded revenues of $7.2 million and a net loss from operations of $2.5
million. The increase in revenues in 1998 over 1997 was the result of a full
year of operations and a higher level of development activities supported by
advances of royalties from publishers of the games under development. The
increased loss in 1998 over 1997 is primarily attributable to the full year of
operations in 1998. The operating losses in both years were the result of the
increasing number of game development projects, for some of which the estimated
costs to complete the development exceeded the expected advances from
publishers, resulting in the recording of losses in current periods. The net
losses in both 1997 and 1998 are accounted for in our statement of operations
as losses from discontinued operations. In addition, we incurred a net loss
from the disposal of IES of $2.6 million, $3.9 million on a pre-tax basis,
representing the write-off of $1.7 million of term loans, $200,000 of
professional fees, $500,000 of estimated operating losses through the disposal
date and the accrual of our remaining estimated funding commitment of $1.5
million described in the preceding paragraph.

Quantitative and Qualitative Disclosures About Market Risk

   Our exposure to market risk relates to changes in interest rates for
borrowings under our senior term loans and our revolving credit facility. These
borrowings bear interest at variable rates. The unsecured notes bear interest
at a fixed rate. Based on our borrowings during 1998, a hypothetical 10%
increase in interest rates would have increased our annual interest expense by
approximately $250,000 and would have decreased our annual cash flow from
operations by approximately $150,000.

Impact of the Year 2000 Issue

   General. Many currently installed computer systems and software products are
coded to accept or recognize only two-digit entries in the date code field.
These systems may recognize a date using "00" as the year 1900 rather than the
year 2000. As a result, computer systems and/or software 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 of
normal business activities. We are exposed to the risk that the systems we, our
customers and vendors depend on to conduct operations are not Year 2000
compliant.

   State of Readiness. We have developed a Year 2000 program that was
structured to address our Year 2000 exposure. Our Year 2000 program focuses on
certain tasks that address critical Year 2000 issues. These tasks include
assessing each of the following:

  .  Our computer hardware and software, including data, networks, servers
     and workstations, human resources systems and financial systems;

  .  Our telephone systems, computer room systems and office equipment; and

  .  Our financial interfaces and leased facilities.

   We also monitor critical suppliers and vendors for Year 2000 readiness as
follows:

  .  We require Year 2000 compliance in all new purchases of hardware and
     software, both for internal use and for the use by our customers;

  .  We regularly monitor vendor information for additional Year 2000
     readiness information and obtain and apply software changes
     appropriately;

  .  We monitor the readiness of our financial services vendors to provide
     timely services;

  .  We are conducting a letter survey of landlords requesting information as
     to the readiness and reliability of building systems including security
     access, elevators and environmental control systems.


                                       28
<PAGE>

   We have substantially completed the process of determining the Year 2000
readiness of our IT systems. We believe that our internal systems, as a whole,
are Year 2000 compliant. Our remaining Year 2000 tasks include:

  .  Migrating employee records and data from legacy computer systems;

  .  Reviewing how our systems interface with those of our financial services
     companies, including payroll functions, direct deposits, health and
     retirement benefits, and customer electronic interfaces;

  .  Completing our review of Year 2000 compliance by critical suppliers and
     vendors;

  .  Implementing a strategy for deploying uniform desktop applications
     across our operations and maintaining desktop systems in a Year 2000
     compliant configuration;

  .  Completing upgrades for data and voice communications equipment; and

  .  Working with landlords to assess Year 2000 issues in building systems.

   We are not currently aware of any Year 2000 problems that would have a
material adverse effect on our business, financial condition or results of
operations. We intend to complete our assessment, and the replacement or
remediation of any non-Year 2000 compliant technologies, by September 1999.

   Costs. As of March 31, 1999, we have expended approximately $100,000 in
connection with Year 2000 compliance efforts. We estimate that the total
remaining cost of our Year 2000 compliance efforts will be approximately
$500,000. Most of these expenses relate to costs for licensing standardized
Year 2000 compliant software, costs for personal computer hardware upgrades and
operating costs associated with time spent by employees in Year 2000 compliance
matters. If we encounter unexpected difficulties, or if we are unable to obtain
compliance information from material third parties, we may need to spend
additional amounts to ensure that our systems are Year 2000 complaint.

   Risks. We provide our IT assurance services for information systems affected
by Year 2000 problems. Although we attempt to contractually limit our liability
for damages arising from errors, mistakes, omissions or negligent acts in
rendering services, our attempts to limit liability may not be successful. Our
failure or inability to meet a customer's expectations could cause our
customer's operations to suffer and, therefore, could give rise to claims
against us or damage our reputation, adversely affecting our business,
operating results and financial condition.

   Although our assessment may be finalized without identifying any material
non-compliant systems operated by us or by third parties, a systemic failure
beyond our control, such as a prolonged telecommunications or electrical
failure, is possible. This type of failure could prevent us from operating our
business. We believe that the primary business risks, in the event of such
failure, would include, but not be limited to, lost business revenues,
increased operating costs or other business interruptions of a material nature,
as well as claims of mismanagement, misrepresentation or breach of contract.
Presently, we believe we are unable to reasonably estimate the duration and
extent of any such interruption, or quantify the effect it may have on our
future revenues.

   Contingency Plan. We have not yet developed a contingency plan to address
the worst-case scenario that might occur if our technologies are not Year 2000
compliant. The results of our Year 2000 simulation testing and the responses
received from the Year 2000 readiness disclosures obtained from critical
providers will be taken into account in determining the need for and nature and
extent of any contingency plans. We intend to complete the development of any
required contingency plan by September 1999.

Effects of Recent Accounting Pronouncements

   In 1998, the Accounting Standards Executive Committee issued Statement of
Position 98-5, "Reporting on the Costs of Start-up Activities," which must be
adopted for fiscal years beginning after December 15, 1998, and the Financial
Accounting Standards Board issued Statement No. 133, "Accounting for Derivative
Investments and Hedging Activities," which must be adopted for fiscal years
beginning after June 15, 1999. The adoption of these statements is not expected
to have a material impact on us.

     data centers at our customers' facilities.

  .  IT Consulting. We serve as consultants with respect to our customers'
     development of innovative applications or improvements to existing
     critical systems.

Industry Background

 Growth of IT Industry

   The demand for third-party IT services has grown substantially in recent
years. Organizations are increasingly using IT to improve the quality of their
products and services, to reduce their costs and to improve operating
efficiencies. IDC forecasts that the United States market for IT services will
grow from an estimated $139 billion in 1998 to $207 billion in 2002. IDC
forecasts that the IT system services segment of the worldwide IT services
market will grow at a compound annual growth rate of approximately 12% over
this period.

   According to Federal Sources, Inc., the United States government is the
world's largest single buyer of IT services and products. The EIA reports that
the United States government's IT budget for fiscal 1999 is approximately $30
billion, nearly double the budget ten years ago. The EIA also estimates that
the outsourced portion of the federal IT budget will be $26 billion in 1999,
with approximately 64% allocated to civilian agencies of the government and 36%
allocated to the Department of Defense.

   We believe that the increasing emphasis by the United States government on
downsizing and reducing budgets will result in the growing use of IT to enhance
productivity and in more testing and upgrading of existing IT systems.

 Trends in Federal IT Industry

   Historically, the United States government purchased IT services and
products primarily through a protracted, competitive bidding process involving
numerous service providers. Recent government procurement reform has
streamlined the government's buying practices, resulting in a more commercial
approach. These changes have led to the following trends in the federal IT
procurement process:

  .  The government now places greater emphasis on an IT service provider's
     past performance. In evaluating contract bids, the government examines
     an IT service provider's technical merit, reputation and references,
     leading to an increasing emphasis on the quality and reliability of IT
     services and products.

  .  The government increasingly awards government-wide acquisition
     contracts, or GWACs. GWACs are contracts awarded by a government agency
     to many IT service contractors to provide IT services and products at
     pre-negotiated prices, terms and conditions. GWACs streamline the
     government's

                                       30
<PAGE>

     procurement process by allowing any government agency to choose IT
     services and products from any agency's existing GWAC rather than going
     through its own protracted contract procurement process.

  .  Government contracts procured by a single agency are increasing in size.
     Government agencies are consolidating more work under single contracts
     to reduce the time and effort required to procure IT services and
     products. These larger contracts favor IT service providers with greater
     management, financial and technical resources and broader service
     offerings. In addition, these contracts may lead to preferred contractor
     relationships for successful IT service providers.

  .  Government agencies have moved toward multiple-award contracts.
     Multiple-award contracts are awarded by one government agency to several
     IT service contractors, each with similar service offerings and
     products. These contracts provide the government agency that awarded the
     contract a choice among IT service providers. In addition, multiple-
     award contracts favor IT service contractors with broad technical
     resources.

   These trends in the federal procurement process have led to the following
responses by IT service providers:

  .  Federal IT service providers are increasing their investments in sales
     and marketing. As the government adopts a more commercial approach to
     contract procurement, IT service contractors must increase their sales
     and marketing efforts. Government-wide acquisition contracts and
     multiple-award contracts require continued sales and marketing efforts
     over the life of the contract because a government agency has the
     freedom to choose among several pre-approved IT service providers.

  .  There is increasing consolidation among federal IT service providers.
     The trends toward government-wide acquisition contracts, multiple-award
     contracts and larger single agency contracts requires IT service
     providers to have greater management, financial, technical and sales
     resources. As a result, IT service providers increasingly seek to
     consolidate complementary businesses.

The AverStar Solution

   We provide high-quality and cost-effective IT services and products
designed to meet all the needs of mission-critical information systems. Our
solution to the challenges presented by the federal IT industry consists of
the following components which we believe differentiate us from our
competitors.

  .  Emphasis on Quality and Reliability. Over our 30-year history, we
     believe that we have established a reputation for providing IT services
     and products of the highest quality and reliability. We have developed a
     company culture that emphasizes and rewards the delivery of services and
     products of the highest quality and reliability. As a result, over the
     last 10 years, we have won over 95% of our government contracts for
     which we have recompeted.

  .  In-Depth Knowledge of Mission-Critical Systems. Mission-critical systems
     are complex and perform vital functions in which even a minor failure
     exposes customers to substantial losses, including potential loss of
     life. We have developed significant expertise in addressing the needs of
     these large, complex systems. For 30 years, we have worked on some of
     the country's most sensitive and critical systems, including NASA's
     manned flight systems and the Health Care Finance Administration's
     Medicare transactions system. We also provide services for commercial
     customers' critical systems.

  .  Highly Developed Project Management Skills. Each of our projects is
     headed by an experienced project manager. The project manager works
     closely with our customers' management and IT personnel to ensure that
     the project is completed on-time and within budget. We currently have
     approximately 100 project managers with an average of over 20 years
     experience in the IT industry.

  .  Comprehensive Offering of Services and Products. We offer a
     comprehensive range of IT services and products. We can support a
     customer throughout the entire life cycle of an information system from
     design and development through deployment and operation.

                                      31
<PAGE>

  .  Expertise in Multiple Technologies. Our IT professionals have experience
     and expertise in diverse technical environments, legacy platforms,
     programming languages and software, as well as newer technologies
     including client/server applications and the Internet. This expertise
     enables us to assist customers in determining the best solutions for
     their specific IT needs. We also have extensive knowledge of customers'
     mission-critical systems and operations, which allows us to design and
     integrate new systems or applications.

Our Business Strategy

   Our goal is to be the leading quality supplier of IT services and software
products for mission-critical systems. To achieve our goal, our strategy is to:

  .  Leverage Our Position in IT Assurance. We intend to continue to leverage
     our position in IT assurance to attract new customers and to provide
     additional services and products to our existing customers. We believe
     that the knowledge we gain concerning our customers' business, processes
     and technologies while performing IT assurance services allows us to
     expand our customer relationships over time.

  .  Pursue Targeted Acquisition Opportunities. Strategic acquisitions of IT
     service providers are an integral part of our growth strategy. We seek
     to acquire companies that operate in defined vertical market niches
     complementary to our current business or that have well established
     relationships with key customers. These acquisitions may allow us to:

      -- Offer products and services which we do not currently provide;

      -- Add new markets and customers which we do not currently serve;
         and

      -- Compete more effectively for larger contracts with increased
         technical, financial and sales and marketing resources.

    Our recent acquisition of CBSI is an example of our targeted
    acquisition strategy. Through CBSI, we acquired several new customer
    relationships as well as significantly increased our IT operations
    capabilities.

  .  Expand Our Commercial Business. We intend to capitalize on our expertise
     and reputation in the federal IT market to compete for commercial
     projects. As the size of IT systems of commercial companies has grown in
     response to the demand for improved product quality, reduced costs and
     improved operating efficiencies, information systems have become
     critical to their businesses. As a result, the need for high-quality IT
     services is likely to grow. We believe that our reputation for high
     quality and reliability together with our position in IT assurance will
     enable us to take advantage of this opportunity in the commercial
     market.

  .  Continue Our Investment in Sales and Marketing. Over the last three
     years, we have significantly strengthened our sales and marketing
     efforts and have increased the number of our employees dedicated to
     sales and marketing from eight to twenty-six as of May 31, 1999. Our
     investment in sales and marketing enables us to compete effectively for
     larger government contracts, to provide the continuous sales presence
     necessary to obtain additional work under government-wide acquisition
     contracts and multiple-award contracts and to expand our commercial
     customer base.

  .  Maintain Our High Level of Customer Satisfaction. We remain focused on
     customer satisfaction which has been a major factor in our past success.
     Our highly qualified, responsive project teams ensure quick and
     effective responses to customers' IT concerns. We believe that
     maintaining our high level of customer satisfaction and the resulting
     long-term relationships provide a stable customer base from which we can
     grow our business.

Our Services and Products

   We provide our customers with an integrated offering of services and
products in four areas: IT assurance, IT development, IT operations and IT
consulting. Through these offerings, we are able to support customers during
all or any particular phase of the life cycle of an information system.

                                       32
<PAGE>

 IT Assurance

   Our IT assurance services include the independent analysis, review, testing,
verification and validation of information systems under development or being
upgraded. Customers increasingly view more of their information systems as
being critical to their operations. This growth in the number of critical
systems, which must operate correctly and be delivered within schedule and cost
constraints, has increased the market demand for our IT assurance services.

   We provide the following types of IT assurance services:

   Systems Assurance. Our systems assurance services involve independent
assessment of the specification, design, implementation and testing of
information systems being developed for our customers. We focus on early
detection of problems so that cost-effective corrections can be made early in
the development cycle. We also evaluate the processes and tools being used by
the systems developer and provide oversight in tracking the customer's schedule
and budget. Our systems assurance methodologies, tools and services verify our
customers' information systems and provide them with comprehensive technical
reports detailing any and all tracking and reporting problems.

   Information Assurance. Our information assurance services include providing
customers with security risk assessments, security policy and architecture
design, and certification and accreditation of IT systems. Our solutions help
customers automate highly secure transmissions of data across communications
networks. With more information systems migrating to Internet and Intranet
applications, the potential threat from computer viruses and computer hackers
increases the demand for these services. We also offer products that provide
customers with the ability to control a user's access to network systems in a
multi-level, secure environment.

   Compliance Assessments. Customers retain us to determine whether a specific
component of an information system complies with their specifications. The
scope of our compliance assessment services may vary from assessing the
readiness of software for operational implementation, to assessing the process,
cost and schedule for an information system upgrade.

   As part of our business strategy, we have begun to apply our expertise in
assessing critical information systems to the commercial IT services market. As
a result of current market demand, the majority of our recent commercial
projects have focused on the Year 2000 problem. We believe that the high demand
for these services presents a significant opportunity for us to expand our
customer base in the commercial IT market. Already, some of the commercial
companies that originally hired us to do Year 2000 work have retained us to
provide broader-based IT assurance as well as IT development services such as
building web-based applications for legacy systems.

 IT Development

   Our IT development services include specification and design, coding and
implementation, system integration, testing and verification, training and
operational deployment of IT systems. We use both our proprietary and
commercially available tools, together with well established procedures, to
develop and implement IT systems. Our many years of experience in performing IT
assurance services on major systems provide us with a competitive advantage as
an IT developer through the use of processes that avoid common development
problems and through the utilization of project management disciplines to
control the cost, schedule and performance of our projects. Our IT development
services specialize in the following:

   Mission Applications. Mission applications involve developing and
maintaining software and systems to support customer-specific programs or
operations.

   Electronic Business. Applications for electronic business involve enabling
legacy systems for web-based access and building new Internet and intranet
applications for government and commercial customers.

                                       33

 IT Operations

   Our IT operations include network and desktop operations and complete data
center operations at our customers' facilities. We install, maintain and
support our customers' network and desktop operations. Our data center
operations include software development, data collection and input, database
archives, report generation and hardware maintenance. We also support customers
in incorporating new technologies and requirements into their operations. As a
provider of end-to-end services for these operations, we frequently call upon
our expertise in IT assurance, IT development and IT consulting to fulfill
particular requirements of an IT operations contract.

   We recently expanded our IT operations services through the acquisition of
CBSI, a company that has significant expertise in providing IT operations
services to several civilian agencies of the federal government.

 IT Consulting

   Our IT consulting services include supporting customers' innovative
applications of new technologies or enhancements to existing critical
information systems. Through our IT consulting services, we gain knowledge of
customers' systems, providing us with opportunities to capture other IT
projects. Our IT consulting services include:

   Technology Studies. When customers want to investigate the application of a
new or developing technology for a particular use, they can engage us to
provide our IT consulting services in order to study feasibility of the
concept, define the scope of the project, plan the detailed steps involved in
phasing in new technology to replace an existing system, or develop a detailed
plan, including schedules and budget, for a development project.

   Prototyping. We develop rapid prototype demonstrations for a variety of
systems or applications.

   Language and Software Tool Development and Services. We deliver custom
language and software tool development products and services to support web-
based or private network systems and to support electronic design and
manufacturing.

  .  Monitoring and Debugging Tools. JWatch, our proprietary software
     debugging tool, provides users with the ability to analyze Java code
     execution and to display data and information to isolate problems and
     repair them within a Java software development environment. We license
     JWatch to software product companies that incorporate it into their
     products. Building on our JWatch technology, we have developed a new
     product, EWatch, which is currently being beta tested. EWatch supports
     monitoring and debugging in a distributed computing environment. We
     expect EWatch to enter the marketplace in late 1999 or early 2000.

  .  Computer-Aided Design Automation Tools. We are a leader in developing
     languages to support the design and simulation of integrated circuits.
     We lead a group of design automation companies in an effort to develop
     an industry solution for the exchange of design information for
     integrated circuits directly between the designer and manufacturer.

  .  Software Languages and Tool Development Services. We have been one of
     the leaders in creating higher order programming languages for building
     software-intensive systems for the United States government. We created
     NASA's HAL/S language, the standard for manned space avionics software,
     and the latest version of Ada, the standard language of the Department
     of Defense.

   These tools and related high-technology capabilities distinguish us and
enable us to capture IT services contracts. In addition, our tools have
intrinsic value of their own. By licensing some of our tools to third-party
distributors, we are able to generate higher margin royalty revenues.

                                       34

Our Markets and Customers

   Our primary customers are agencies of the United States government. Our ten
largest contracts by revenues are all with United States government agencies
and accounted for approximately 45% of our 1998 pro forma revenues. In 1998,
the United States Navy accounted for approximately 15% of our pro forma
revenues, and NASA accounted for approximately 12% of our pro forma revenues.
These revenues are the result of various contracts awarded by several
procurement offices within these agencies. Our experience has indicated that
particular contracts are subject to the discretion of each procurement office.
Of the 20 government agencies with the largest IT budgets for the government's
1999 fiscal year, we have contracts with 16. The breadth of our government
contract base and service offerings provides us with less dependence on any one
agency and more opportunities to sell additional services to our customers.

   The following chart illustrates a selected number of our customers across
our markets from January 1998 to the date of this prospectus.

Illustrative Customer Relationships

   We have long standing relationships with several of our customers. Over
time, we have been successful in expanding the range of services that we
provide to these customers.

 National Aeronautics Space Agency

   The National Aeronautics and Space Administration, or NASA, is currently one
of our largest customers. Our contractual relationships with NASA go back
nearly 30 years. In the early 1970s, we won a contract to design a programming
system for the next generation of manned spacecraft operations, including the
space shuttle and space station programs. We designed and developed an advanced
programming language called HAL/S which NASA adopted as a standard for avionics
software for manned applications. HAL/S was used to program the software for
all on-board computers and is still used today for all software updates for
each space shuttle flight. Based on the success of HAL/S for the space shuttle,
NASA adopted HAL/S for other missions including on-board programming for the
Galileo spacecraft that recently visited Jupiter. We continue to maintain HAL/S
for NASA today.

   During the development and initial operational phases of the space shuttle,
we played several key contracting roles for NASA. We developed the design
requirements for the operating system for the on-board system that is still in
use today. We were one of two subcontractors involved, together with one prime
contractor, in the development of the backup flight software system that the
crew uses in the event of catastrophic failure to the space shuttle's primary
on-board flight system. We were also the prime contractor for the validation of
the flight navigation system. We invented and implemented the Dynamic
Integrated Test Technique, a concept for fully-integrated testing of the
software and hardware systems while the shuttle is on the launch pad with the
crew in the cockpit, just prior to launch. This test is recognized as the
critical end-to-end evaluation of the shuttle's avionics, software, crew and
communications prior to an actual flight.

   Following the Challenger accident in 1986, NASA recommended that we perform
a complete audit of all software processes and the key interfaces of software
to hardware to determine whether the shuttle was ready to fly again. As a
result of our staffing up to perform this high-visibility task, NASA continued
our role as the independent verification and validation contractor to assess
all changes to the software made for each shuttle flight. Today, we continue to
perform this role for NASA and our contract has expanded to include the space
station program, ground control systems and robotic spacecraft. Also, within
the scope of this contract, we oversee the avionics and software development
for the X-33 spacecraft and are supporting NASA in the testing of its software
for a ground control system.

   In 1994, because of our reputation on past work with NASA, we won a contract
to perform independent verification and validation for NASA's Earth Observing
System and Data Information System, or DIS. Under this contract, we support
NASA in the testing and integration of the DIS, which will archive
approximately one million megabytes of environmental data per day, collected
from satellite-based sensors. The DIS will distribute data over the Internet to
scientific and commercial users throughout the world.

 United States Navy

   The United States Navy was one of our first and continues to be one of our
largest customers. The first contract we received from the Navy over 30 years
ago was to define the ground support requirements for the yet-to-be-deployed P-
3C anti-submarine warfare land based aircraft. Since that time, we have been a
major contributor to every version of P-3 aircraft that has been delivered to
the Navy fleet. Our contributions have included definition of system and
software requirements, generation of detailed equipment and software
specifications, design and development of system test and integration
facilities, validation and verification of system performance in the lab and
onboard the aircraft, and development of training media and the training of
fleet personnel.


                                       37
<PAGE>

   Other major Navy programs we have supported in similar capacities include
the S-3A carrier-based anti-submarine warfare aircraft, used to detect and
destroy enemy submarines; the executive helicopter, used for transporting the
President of the United States and his staff; the Light Airborne Multi-Purpose
System Helicopter, used onboard ships for submarine and anti-missile detection
and defense; and the Landing Craft Air Cushion vehicle, or LCAC, used to
transport personnel and equipment in hostile, shallow water operations. For the
LCAC, we also provide the crews used to operate the test craft, and perform all
logistics support functions for the United States Navy for all LCACs deployed
throughout the world.

   For over 15 years, we have performed analytical, design, testing and
validation efforts associated with the integration of global positioning
systems and other navigation systems into a wide range of Navy and joint
aircraft and ship programs. We have supported the design, development, testing
and operation of the Naval Wargaming System at both the Naval War College and
Tactical Training Group Pacific for approximately 20 years. In addition, for
approximately 12 years, we have worked closely with the Navy in the design,
development, validation and operation of the software used to resolve
operational problems and test future avionic upgrades for the EA-6B aircraft.

 Delphi Automotive Systems

   Delphi Electronics Systems, a division of Delphi Automotive Systems, a
leading manufacturer of automotive control systems, has been one of our largest
commercial customers, and we have sustained our relationship with them over a
15-year period.

   In the mid-1980s, Delphi decided to design and build a proprietary software
development system to program the computer chips used in automotive control
systems. With over six million vehicles equipped on a yearly basis and a
significant increase in the number of individual computers involved to control
and monitor various parts of the vehicle, the needs for the programming system
were threefold:

  .  To enhance the productivity and lower the time for development to meet
     manufacturing schedules;

  .  To improve the efficiency of the code generated to reduce memory needs;
     and

  .  To enhance reliability and maintainability because of the critical
     nature of the functions performed for the vehicle.

   At that time, these needs were not met through the use of available
programming tools. We won a contract in 1985 to develop this programming system
and the related compilers for several of the major microcomputer chips being
used in vehicles at that time.

   Following the initial development of the Delphi system, we designed and
developed a complete configuration management system to support the building
and control of the software used in Delphi-equipped vehicles and computers. Our
role was extended to include building new versions of compilers for the
microcomputer chips being planned for future Delphi-equipped vehicles. In
addition, Delphi asked us to convert our software from a mainframe to a fully
integrated workstation environment. During the 1990s, we built an electronic
specification system for distributing and controlling documentation for the
vehicle-based electronic systems. This system is used to distribute and control
documentation on a worldwide basis. Delphi now uses this system to distribute
and control other information beyond the documentation of vehicle-based
electronics systems. We have recently added a web-based interface to the
system.

Sales and Marketing

   Over the last four years, we have significantly increased the investment in
our sales and marketing efforts. As of May 31, 1999, we had 26 employees
dedicated to our sales and marketing efforts. These employees all belong to our
corporate-wide business development team. The majority of these employees work
with project managers and operating teams to pursue new business. Several of
our sales and marketing employees work primarily at the corporate level to
identify and develop new sales targets and to obtain government awards.


                                       38
<PAGE>

   Our management works to foster an environment in which every employee shares
the responsibility for our sales and marketing and internal growth. In addition
to our dedicated sales and marketing personnel, many other employees spend
significant amounts of their time on sales and marketing activities. We seek to
ensure that each employee understands how he or she can contribute to our
growth, whether by communicating to management opportunities for new business,
by building a new customer relationship or by supporting a proposal.

   As we grow, we will continue to invest our resources in sales and marketing.
Our continually growing sales presence is necessary to compete for larger,
long-term government contracts, and to develop the ongoing relationships with
present and prospective customers demanded by the prevalence of multiple-award
government contracts and by our expansion of commercial opportunities.

   A significant portion of our new business derives from existing customer
relationships. We frequently leverage our strong incumbent positions to expand
the scope of our customer relationships. In addition, we identify new contract
opportunities through the use of industry contacts, attendance at conferences
and review of publications that identify new contracting opportunities.

   While the services and products we provide to commercial customers are the
same as or similar to those we offer to government customers, the process of
selling to commercial customers is somewhat different. A portion of our sales
and marketing staff is, therefore, dedicated to selling services to commercial
customers. We expect to continue to expand our commercial sales and marketing
staff. We also have a sales effort dedicated to licensing our technology and
products to companies that sell our products and pay us royalties.

   We have an incentive compensation program for sales and marketing personnel.
Incentive awards are based on achievement of our goals for profitability and
bookings of new business.

Contracts

 Government Contracts

   We have several multi-year contracts with United States government agencies,
typically for three to five years. These contracts require us to provide a
broad range of requested services. We receive specific assignments under a
given contract through the issuance by the government of task orders. Task
orders describe the specific assignment, the number of employees allocated to
the assignment and the estimated cost, fee and travel allocated to the
assignment.

   Under our Government Services Agency Schedule, which is a type of GWAC, any
government agency may purchase IT services and products at pre-approved prices
and without any additional competitive bidding. The term of our current
Government Services Agency Schedule contract expires in September 2002.

 Commercial Contracts

   Typically, commercial contracts require us to complete a specific task or
provide a defined range of services and support. Payments are usually made
incrementally during the performance of each specific work assignment.
Currently, we are working to expand our customer base and increase the sales of
our products and services in the commercial IT market. Most of our existing
commercial contracts are fixed-price contracts.

Backlog

   Backlog represents management's estimate of our aggregate realizable
revenues over the term of all of our contracts, including any option periods.
However, backlog is not necessarily indicative of future revenues. Our contract
backlog was approximately $450 million as of March 31, 1999. Our backlog is
composed of:

  .  Customer authorized contract values for which the customer has set
     aside, appropriated or committed funds for specifically identified
     services, products, tasks or delivery orders; and

                                       39
<PAGE>


  .  Management's estimate of the realizable contract values for all expected
     future services, products, tasks or delivery orders, for which funds
     have not yet been set aside, appropriated or committed.

   The actual timing of our receipt of revenues, if any, on projects included
in our backlog could change because many factors affect the scheduling of
projects. In addition, cancellations or adjustments to contracts may occur. Our
backlog is subject to large variations from quarter to quarter as existing
contracts are renewed or new contracts are awarded. Additionally, virtually all
of our backlog represents contracts with the United States government which may
be terminated at any time for any reason.

Competition

   We experience significant competition in all areas of our business. In
general, the markets in which we compete are not dominated by a single company
or a small number of companies. Rather, a large number of companies offer
services that overlap and are competitive with our services and products.
However, we compete regularly with approximately seven different competitors in
our IT assurance service offerings, 18 in our IT development service offerings,
six in our IT operation service offerings and four in our IT consulting service
offerings.

   We believe that the principal competitive factors in our business are
technical understanding, management capability, past contract performance,
personnel qualifications and price. While we have considerable experience,
there are many other contractors that have comparable skills. Many of our
competitors are significantly larger and have greater financial resources than
we do. In addition, many of our competitors have significantly more experience
in the commercial IT market than we do.

Proprietary Information

   Although much of our work is performed for the United States government,
wherever possible we attempt to retain proprietary rights in our products. We
rely on copyright, patent and trade secret laws and internal non-disclosure
safeguards, as well as restrictions incorporated into software product license
agreements and other contractual provisions to protect our proprietary rights.
However, these measures may not prevent the unauthorized disclosure or use of
our technical knowledge, practices or procedures, or prevent others from
independently developing similar knowledge, practices or procedures. Further,
the government may acquire certain proprietary rights to software programs and
other products that we develop while performing services under government
contracts. The government may disclose this information to others, including
our competitors. Disclosure or loss of control over our proprietary information
could have a material adverse effect on our business, financial condition and
results of operations.

Employees

   As of May 31, 1999, we had a total of 1,765 employees, consisting of 1,643
full-time and 122 part-time or temporary employees. Of our total full-time
employees, approximately 1,499 are in engineering, technical and technical
support positions, 118 are in general and administrative positions and 26 are
in sales and marketing positions. None of our employees are covered by a
collective bargaining agreement.

   We have several full-time employees dedicated to recruiting technical and
administrative professionals and managing our human resources. As part of our
retention efforts, we seek to minimize turnover by emphasizing our reputation,
the nature of our work, our work environment, our encouragement of technical
publications, our participation in professional societies and our competitive
compensation packages.

Certain Regulatory Matters

   United States government contracts are subject to the Federal Acquisition
Regulations, or FAR, and other agency FAR supplements. Major contracts are also
subject to the Truth in Negotiations Act, or TIN Act, and Cost Accounting
Standards, or CAS. Among other procurement regulations, the FAR contains the
cost

                                       40
<PAGE>

principles for setting contract prices while the TIN Act requires us to provide
current, accurate and complete cost or pricing data in connection with the
negotiation of a contract. CAS requires consistency of accounting practices
over time and compliance with specific cost accounting criteria.

   To the extent that a company fails to comply with procurement requirements,
the United States government may adjust contract prices. Additionally, changes
in cost accounting practices are subject to a required procedure for
negotiation of the cost of the change. The United States government is
protected from paying increased costs resulting from accounting changes.
Finally, the United States government has the right to audit contractors for
three years after final payment. Accordingly, our revenues are subject to
adjustment.

   United States law and regulations restrict and regulate the export of
technology as well as goods and commodities provided by United States
businesses to controlled foreign subsidiaries and affiliates. We are subject to
certain of these regulations with respect to our technology that is sold to
non-United States customers.

Facilities

   We currently lease approximately 310,000 square feet of space comprised of
24 facilities. We consider these properties to be modern, well maintained and
suitable for their intended purposes. We lease our principal executive and
administrative offices and software facility located in 38,800 square feet of
space in Burlington, Massachusetts. This lease expires in 2003. We also have
offices located in:

  .  Fountain Valley, Huntington Beach, Pasadena, Point Mugu, Sacramento, San
     Diego and Santa Clara, California;

  .  Colorado Springs, Colorado;

  .  Panama City, Florida;

  .  Baltimore, Greenbelt and Lexington Park, Maryland;

  .  Billerica, Massachusetts;

  .  Kansas City, Missouri;

  .  Lawton, Oklahoma;

  .  Portland, Oregon;

  .  Warminster, Pennsylvania;

  .  Charleston, South Carolina;

  .  Houston, Texas; and

  .  Arlington, Fairfax and Vienna, Virginia.

Classified Board of Directors

Directors Compensation

   In September 1998, we began compensating our non-employee directors $20,000
per year, paid in arrears in semi-annual increments. In addition, we reimburse
each non-employee director for customary and reasonable out-of-pocket expenses
for attending each board of directors or committee meeting. At the discretion
of the board of directors, non-employee directors may be granted options to
purchase common stock at the then prevailing fair market value. We also have a
consulting agreement with Messrs. Levy and Schulte. Please see "Certain
Relationships and Related-Party Transactions." Prior to September 1998,
directors received no cash compensation for their service on our board of
directors or any of our committees.

Committees of the Board

 Audit Committee

   The audit committee currently consists of Mary Ann Gilleece (chair), Peter
M. Schulte and Michael B. Alexander. After this offering, the audit committee
will consist of Mary Ann Gilleece (chair) and Peter M. Schulte. The audit
committee selects and evaluates our independent auditors, reviews the scope of
the annual audit with management and our independent auditors, consults with
management and our independent auditors about our systems of internal
accounting controls and reviews the non-audit services performed by our
independent auditors.

 Compensation Committee

   Our compensation committee currently consists of Peter M. Schulte (chair),
Joel N. Levy and John C. Rennie. The compensation committee is responsible for
approving or recommending salaries and benefits for our employees,
consultants, directors and other individuals compensated by us. The
compensation committee also reviews our benefit plans.

 Option Committee

   Our option committee currently consists of Peter M. Schulte (chair) and
Joel N. Levy. The option committee is responsible for approving or
recommending option grants, and administering our long-term incentive plan.

1998 Long Term Incentive Plan

   General. Our 1998 long term incentive plan was approved by our board of
directors and our stockholders in June 1998. The purpose of our 1998 long term
incentive plan is to enable us to attract, retain and reward employees,
officers and directors and to strengthen the mutuality of interests between
our employees, officers and directors and our stockholders, by permitting them
to participate in our ownership. Pursuant to the plan, we may grant options
intended to qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, non-qualified stock options, stock appreciation
rights, restricted stock, deferred stock, stock purchase rights or other
stock-based awards.

   Shares reserved for issuance. A total of 3,349,447 shares of common stock
have been reserved for issuance under the plan. Appropriate adjustments in the
aggregate number of shares subject to the plan will be made in the event of
any recapitalization, dividend of stock or property other than cash, stock
split, reclassification or other change in corporate structure affecting the
common stock. As of March 31, 1999, we have granted stock options to purchase
1,513,433 shares of common stock.

   Eligibility. Our employees, officers and directors who are responsible for
or contribute to the management, growth and/or profitability of our business
are eligible to be granted awards under the plan. However, only our employees
are eligible to receive incentive stock options.

   Administration. Our stock option committee is authorized to administer the
plan, including the selection of individuals eligible for grants under the
plan and the terms of grants. Generally, the stock option committee has broad
authority to amend the plan to take into account changes in applicable
securities and tax laws and accounting rules, as well as other developments.

   We may grant any of the following, or any combination of the following,
types of awards under the plan:

   Stock options. We may grant incentive stock options and non-qualified stock
options. A stock option may have a term of not more than ten years. Our option
committee determines the price per share, which may be equal to, greater than
or less than the fair market value of common stock purchasable under stock
options granted under the plan on the date of grant based on the following
factors:

  .  The price per share of common stock purchasable under an incentive stock
     option cannot be less than the fair market value of our common stock on
     the date of grant; and

                                      46
<PAGE>


  .  In the case of an incentive stock option granted to an employee who, at
     the time of grant, owns common stock with more than ten percent (10%) of
     the total combined voting power of our outstanding common stock, the
     price per share of common stock cannot be less than one hundred ten
     percent (110%) of the fair market value of our common stock on the date
     of grant.

The fair market value of our common stock is its closing price on the stock
exchange on which it is listed; if it is not listed, the fair market value is
determined by the option committee after considering various factors, including
our operating results, transactions with third parties involving the exchange
of our stock, and independent valuations of our stock which we receive
periodically.

   Stock appreciation rights. A stock appreciation right is the right to
surrender to us all or a portion of a stock option in exchange for an amount
equal to the difference between:

  .  The fair market value, as of the date any part of a stock option is
     surrendered, of the shares of common stock covered by any part of a
     stock option, subject to pricing provisions, and

  .  The aggregate exercise price of any part of a stock option.

   A stock appreciation right granted with respect to a given stock option
shall terminate and no longer be exercisable upon the termination or exercise
of the related stock option, subject to provisions specified by the stock
option committee.

   Restricted stock. A restricted stock award entitles the holder to receive
shares of common stock at the end of a restricted period determined by the
stock option committee. During the restricted period, the holder is not
permitted to sell, transfer, pledge or assign shares of restricted stock. The
stock option committee may provide for the lapse of such restrictions in
installments and may accelerate or waive such restriction in whole or in part,
based on service, performance and other criteria as the stock option committee
may determine.

   Deferred stock. A deferred stock award entitles the holder to receive shares
of common stock at the end of a specified deferral period. The stock option
committee shall determine, among other things, the duration of the period
during which, and the conditions under which, receipt of the common stock will
be deferred.

   Stock purchase rights. Stock purchase rights entitle the holder to purchase
common stock, including deferred stock and restricted stock:

  .  At its fair market value on the date of grant;

  .  At fifty percent (50%) of the fair market value on the date of grant;

  .  At an amount equal to book value on the date of grant; or

  .  At an amount equal to the par value of the common stock on the date of
     grant.

   Other stock-based awards. We may also make other awards of common stock and
other awards that are valued in whole or in part by reference to, or are
otherwise based on, common stock, including performance shares, convertible
preferred stock, convertible debentures, exchangeable securities and stock
awards or options valued by reference to book value or our performance.

termination until the earlier of his 65th birthday or the date specified by our
long-term disability plan:

  .  His then current salary and bonus for 12 months following his
     termination, and $10,000 per month thereafter, less our medical benefits
     described below;

  .  Any earned but unpaid vacation, salary and bonus amounts;

  .  Continued use of a company car; and

  .  Benefits under our long-term disability policy and medical benefits from
     the date of termination until the earlier of the date specified by our
     disability policy or his 65th birthday.

estate in the event of his death, is entitled to receive any earned but unpaid
vacation, salary and bonus amounts.

              CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

   In connection with the acquisition of Intermetrics by an investor group led
by current management, we obtained a $35.0 million credit facility with
Massachusetts Mutual Life Insurance Company, or MassMutual, and certain
affiliates of MassMutual. This facility comprised $25 million in senior debt,
$5 million in subordinated debt and $5 million in revolving credit. In
connection with this facility, MassMutual and its affiliates received warrants
to purchase shares of common stock. In connection with our acquisition of Pacer
in February 1998, these warrants were exchanged for 605,286 shares of our
common stock. At December 31, 1998, we owed $23.6 million under the senior term
agreement, $5 million under the subordinated debt agreement and $2.5 million
under the revolving credit agreement. An additional $2.5 million was available
under the revolving credit agreement. We repaid the $2.5 million borrowed under
the revolving credit early in 1999 as we collected outstanding receivables. In
March 1999, we refinanced our outstanding debt in conjunction with our
acquisition of CBSI, and repaid our outstanding debt of $23.2 million under the
senior term agreement. Currently, we maintain the $5 million subordinated debt
agreement with MassMutual. MassMutual is also one of our lenders under our
credit agreement with First Union.

   In connection with our divestiture of IES, we:

  .  Provided a $2.0 million credit facility to IES;

  .  Received a $1.3 million promissory note from IES; and

  .  Extended the due date of two $200,000 secured notes from IES.

   Outstanding amounts under the credit facility and the promissory note bear
interest at a rate of 8.5% per year. Outstanding amounts under the secured
notes bear interest at a rate of 10.5% per year. AfterDecember 31, 1999, we are
not required to fund any additional amounts under the credit facility, which
matures on December 31, 2001. The promissory note and secured notes mature on
December 31, 2001.

   Mr. Levy and Mr. Schulte, both members of our board, are the principal
officers of Joel N. Levy/Peter M. Schulte, LLC, or L&S, which supported the buy
out of Intermetrics in August 1995. We have retained L&S to provide financial,
strategic and business planning and consulting services, including analysis and
advice with respect to programs relating to value of our common stock. The
consulting agreement with L&S terminates on the first anniversary of this
offering. The total amounts of fees paid to L&S by us in 1996, 1997 and 1998
were $100,000, $200,000 and $263,000, respectively.

   J. Fernando Niebla was founder, chairman and chief executive officer of
Infotec Development Inc. until it was merged into Pacer, and vice-chairman of
Pacer until we acquired Pacer. In connection with our formation, Mr. Niebla
entered into a repurchase agreement with us. This agreement provides that
during 1998, 1999, 2000 and 2001, he can require us to repurchase some of his
shares of common stock. Our total cost to repurchase all of the shares of his
common stock under this agreement is $1,557,000. However, approximately
$1,000,000 of such amount will be paid by cancellation of the outstanding
indebtedness owed to us by Mr. Niebla. Mr. Niebla's right to require us to
repurchase some of his shares of common stock terminates upon the closing of
this offering.

   Each of our stockholders, including executive officers, who own 3% or more
of our common stock calculated on a fully diluted basis have granted us a right
of first refusal to purchase their shares at the prevailing market price. For
three years following the date of this prospectus, each of these stockholders,
other than MassMutual and its affiliates, must offer their shares to us before
they may sell their shares on the public market. If we do not buy these shares,
then these stockholders may sell their shares on the public market.

                           DESCRIPTION OF SECURITIES

   The following descriptions of our common stock and preferred stock, and
provisions of our certificate of incorporation and bylaws, reflect changes that
will occur upon the filing of an amended and restated certificate of
incorporation immediately prior to the closing of this offering.

   Our authorized capital stock consists of 25,000,000 shares of common stock,
par value $.001 per share, and 1,000,000 shares of preferred stock, par value
$.001 per share.

Common Stock

   As of the date of this prospectus, there are 6,879,744 shares of common
stock outstanding and held of record by 111 stockholders. Stockholders do not
have cumulative voting with respect to the election of directors. There will be
10,880,655 shares of common stock outstanding upon the closing of this
offering. Holders of common stock are entitled to one vote for each share on
all matters submitted to a vote of stockholders. 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. Stockholders will not be liable for
any further calls or assessments. Holders of common stock are entitled to
receive dividends, if, as and when declared by the board of directors out of
funds legally available for such purposes, subject to any dividend preferences
of any outstanding preferred stock. Upon our liquidation, dissolution or
winding up, the holders of common stock are entitled to share ratably in our
assets available for distribution, subject to the preferential rights of any
outstanding preferred stock. Holders of the common stock have no preemptive,
subscription, redemption or conversion rights. Upon the closing of this
offering, there will be no shares of preferred stock outstanding. 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 we may designate and issue in the future.

Preferred Stock

   As of the date of this prospectus, there are no shares of preferred stock
outstanding. Upon the closing of this offering, the board of directors will be
authorized, without further stockholder approval, to issue from time to time up
to an aggregate of 1,000,000 shares of preferred stock in one or more series.
The board of directors may fix or alter the designations, preferences, rights
and any qualifications, limitations or restrictions of the shares of each of
these series, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption, redemption price or prices, liquidation
preferences and the number of shares constituting any series or designations of
these series. We have no present plans to issue any shares of preferred stock.

Stock Options

   Options to purchase a total of 3,349,447 shares of common stock may be
granted under our stock option plan. As of the date of this prospectus, there
are outstanding options to purchase a total of 1,513,433 shares of common stock
under our stock option plan. Of these, stock options to purchase 757,055 shares
are currently exercisable and options to purchase 504,180 shares will become
exercisable upon the closing of this offering. As soon as practicable following
the closing of this offering, we intend to file a registration statement on
Form S-8 which will register the offer and sale of the shares to be issued upon
exercise of these options. Upon the filing of the Form S-8, these shares will
be immediately available for sale in the public market, subject to the terms of
lock-up agreements entered into between certain of these option holders and the
underwriters.

   Anti-Takeover Effects of Certain Provisions of Delaware Law and Our
Certificate of Incorporation and Bylaws

   Delaware Law. We are subject to the provisions of Section 203 of the
Delaware General Corporation Law, or the DGCL. Section 203 of the DGCL
generally prohibits a publicly-held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an
interested stockholder, unless the interested stockholder

                                       55
<PAGE>

attained that status with the approval of the board of directors or unless the
business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to the interested stockholder. Subject to exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, fifteen percent (15%) or more
of a corporation's voting stock. The provisions of Section 203 of the DGCL are
intended to assure that the price that stockholders receive for the common
stock in certain transactions is fair in relation to the market value of and
the prices paid by the "interested stockholder" in its initial acquisitions of
common stock and to allow the board of directors and the stockholders to
prevent the consummation of such a transaction because it may not be in our
best interest or in the best interest of our stockholders. Under those
circumstances in which this statute would apply, minority stockholders may
prevent a transaction favored by a majority of stockholders. This statute could
prohibit or delay the accomplishment of mergers or other takeover or change in
control attempts with respect to us and, accordingly, may discourage attempts
to acquire us.

   Our Certificate of Incorporation and Bylaws. Certain provisions of our
certificate of incorporation and bylaws, which will be in effect upon the
closing of this offering and which are described in the following paragraphs,
may be deemed to have an anti-takeover effect and may delay, defer or prevent a
tender offer or takeover attempt that a stockholder might consider in its best
interest, including those attempts that might result in a premium over the
market price for the shares held by stockholders. However, these provisions are
designed to help to ensure that stockholders are treated fairly and equally in
a multi-step acquisition, and are intended to encourage persons seeking to
acquire control of us to pursue their acquisition in arms-length negotiations
with our board of directors.

   Classified Board of Directors. Our board of directors is divided into three
classes of directors serving staggered terms. The terms of our current
directors expire at the 2000, 2001 or 2002 annual stockholders meeting. One
class of directors will be elected at each annual stockholders meeting for a
three-year term. This classification of directors may deter stockholders from
changing the composition of our board of directors in a relatively short period
of time. At least two annual stockholders meetings, instead of one, generally
will be required to change the majority of directors. Because of the additional
time required to change the directors, classification of directors also may
delay the removal of our current management team. A classified board of
directors helps to assure the continuity and stability of our board of
directors and our business strategies and policies because generally a majority
of directors at any given time will have had prior experience as directors.

   Board of Directors Vacancies. The certificate authorizes the board of
directors to fill vacant directorships or increase the size of the board of
directors. In addition, the certificate permits stockholders to remove
directors only for cause. This may deter a stockholder from removing incumbent
directors or simultaneously gaining control of the board of directors by
filling the vacancies created by that removal with its own nominees.

   Stockholder Action; Special Meeting of Stockholders. The certificate
provides that stockholders may only take action at duly called annual or
special meetings of stockholders and not by written consent. The certificate
further provides that special meetings of stockholders may be called only by
the president, the chief executive officer, chairman of the board of directors
or a majority of the board of directors. These provisions may delay a
stockholders vote for a proposal over the objection of the board of directors.

   Advance Notice Requirements for Stockholder Proposals and Director
Nominations. The bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must deliver a
written notice to our principal executive offices within a prescribed time
period. The bylaws also specify requirements as to the form and content of a
stockholder's notice. These provisions may preclude stockholders from bringing
matters before an annual meeting of stockholders or from making nominations for
directors at an annual meeting of stockholders. Advance notice requirements may
also delay a contest for the election of directors, and discourage or deter a
tender offer or takeover attempt.

   Authorized But Unissued Shares. The authorized but unissued shares of common
stock and preferred stock are available for future issuance without stockholder
approval, subject to limitations imposed by the Nasdaq

                                       56
<PAGE>

National Market. These additional shares may be utilized for a variety of
corporate purposes, including future public offerings, acquisitions and
employee benefit plans. The existence of authorized but unissued and unreserved
common stock and preferred stock could complicate or discourage an attempt to
obtain control of us by means of a proxy contest, tender offer, merger or
otherwise.

   Restrictions on Certain Business Combinations. The certificate contains
provisions which are substantially similar to Section 203 of the DGCL. Such
provisions may dely or discourage mergers or other acquisition attempts with
respect to us.

   Vote Required to Amend our Certificate of Incorporation and Bylaws. Subject
to certain exceptions, our certificate and bylaws require the vote of 80% of
the stockholders to amend, repeal or adopt any provision inconsistent with the
anti-takeover and indemnification provisions discussed in this prospectus. This
supermajority vote prevents a controlling stockholder from avoiding the
requirements of these provisions by simply amending or repealing such
provisions.

Limitation of Liability and Indemnification Matters

   To the extent permitted under the DGCL, the certificate limits the personal
liability of our directors to us or our stockholders for monetary damages for
any breach of fiduciary duty as our directors. Under the DGCL, our directors
have a fiduciary duty to us that is not eliminated by this provision of the
certificate and, in appropriate circumstances, injunctions and other
nonmonetary relief will remain available. This provision also does not affect
the directors' responsibilities under any other laws, including the federal
securities laws.

   Section 145 of the DGCL enables a corporation to indemnify its directors and
officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers. However, this provision
does not eliminate or limit the liability of a director:

  .  For any breach of the director's duty of loyalty to the corporation or
     its stockholders;

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

  .  For payments of dividends or approval of stock repurchases or
     redemptions that are prohibited by the DGCL; or

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

   Our certificate of incorporation provides that we may fully indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that the
person is or was one of our directors or officers or is or was serving at our
request as a director or officer of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, against expenses
(including attorney's fees), judgments, fine and amount paid in settlement
actually and reasonably incurred by that person in connection with any
threatened, pending or completed action, suit or proceeding.

   We believe that the provisions of our certificate and bylaws are necessary
to attract and retain qualified directors and executive officers. Our bylaws
also permit us to secure insurance on behalf of any officer, director, employee
or other agent for any liability arising out of his or her actions, regardless
of whether the DGCL would permit indemnification. We have obtained liability
insurance for our officers and directors.

   At present, there is no pending litigation or proceeding involving any

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has not been any public market for our common
stock. We cannot predict the effect, if any, that market sales of shares of
common stock or the availability of shares of common stock for sale will have
on the prevailing market price of our common stock. Nevertheless, sales of
substantial amounts of common stock in the public market, or the perception
that such sales could occur, could adversely affect the market price of our
common stock and could impair our future ability to raise capital through the
sale of our equity securities.

   Upon the closing of this offering, we will have an aggregate of 10,880,655
shares of common stock outstanding, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options. Of the
outstanding shares, the 4,000,000 shares being sold in this offering will be
freely tradable, subject to the lock-up agreements and the right of first
refusal described below. Additional shares will be available for sale in the
public market as follows:

                    register the offer and sale of shares of common stock
                    issuable upon the exercise of options granted under our
                    stock option plan
</TABLE>

   In general, under Rule 144, as currently in effect, a person, or persons
whose shares are required to be aggregated, including an affiliate, who has
beneficially owned shares for at least one year is entitled to sell, within any
three-month period commencing 90 days after the date of this prospectus, a
number of shares that does not exceed the greater of:

  .  1% of the then outstanding shares of common stock, approximately 108,881
     shares, immediately after this offering; or

  .  The average weekly trading volume in the common stock during the four
     calendar weeks preceding the date on which notice of that sale is filed,
     subject to restrictions.

   In addition, a person who is not deemed to have been our affiliate at any
time during the 90 days preceding a sale and who has beneficially owned the
shares proposed to be sold for at least two years is entitled to sell those
shares under Rule 144(k) without regard to the requirements described above. To
the extent that shares are acquired from our affiliate, the acquiring person's
holding period for the purpose of effecting a sale under Rule 144 generally
commences on the date of transfer from the affiliate.

   As of the date of this prospectus, options to purchase a total of 1,513,433
shares of common stock are outstanding, of which options to purchase 757,055
shares are currently exercisable. Of the options to purchase 756,378 shares of
common stock that are not currently exercisable, options to purchase 504,180
shares of common stock shall immediately vest and become exercisable upon the
closing of this offering. Upon the commencement of this offering, we intend to
file a registration statement to register the 1,836,014 shares of common stock
reserved for issuance under the stock option plan. That registration statement
will automatically become effective upon filing. Accordingly, shares issued
upon the exercise of stock options granted under the stock option plan will be
eligible for resale in the public market from time to time, subject to vesting
restrictions and, in the case of some of the options, the lock-up agreements
and the right of first refusal referred to below.

   Our directors and officers and stockholders who hold 6,871,537 shares in the
aggregate, together with the holders of options to purchase 1,513,433 shares of
common stock, have agreed that they will not sell, directly or indirectly, any
shares of common stock without the prior written consent of Bear, Stearns & Co.
Inc. for a period of 180 days from the date of this prospectus. Please see
"Underwriting."


                                       58

   Except in limited circumstances, we have agreed not to sell or otherwise
dispose of any shares of common stock during the 180-day period following the
date of the prospectus.

   Stockholders who own more than 3% of our common stock calculated on a fully
diluted basis, have granted us a right of first refusal to purchase their
shares at the prevailing market price. For three years following the date of
this prospectus, these stockholders, other than MassMutual and its affiliates,
must offer their shares to us before they may sell their shares on the public
market. If we do not buy these shares, then these stockholders may sell their
shares on the public market.

   The underwriters of this offering named below, for whom Bear, Stearns & Co.
Inc. and Legg Mason Wood Walker, Incorporated are acting as representatives,
have severally agreed with us, subject to the terms and conditions of the
underwriting agreement, to purchase from us the aggregate number of shares of
common stock set forth opposite their respective names below:

</TABLE>

   The underwriting agreement provides that the obligations of the several
underwriters are subject to approval of certain legal matters by counsel and to
various other conditions. We have agreed to indemnify the several underwriters
against certain liabilities, including liabilities under the Securities Act,
and where such indemnification is unavailable, to contribute to payments that
the underwriters may be required to make in respect of such liabilities. The
nature of the underwriters' obligations is such that they are committed to
purchase and pay for all of the above shares of common stock if any are
purchased.

   If the underwriters sell more than the total number set forth in the table
above, the underwriters have an option to buy up to an additional 600,000
shares to cover such sales from us. The underwriters may exercise that option
for 30 days. If any shares are purchased pursuant to this option, the
underwriters will severally purchase shares in the same proportion as set forth
in the table above.

   The underwriters, at our request, have reserved for sale at the initial
public offering price up to 200,000 of the shares of common stock to be sold in
this offering for sale to our employees and directors and other persons
designated by us. The number of shares available for sale to the general public
will be reduced to the extent that any reserved shares are purchased. Any
reserved shares not so purchased will be offered by the underwriters on the
same basis as the other shares offered hereby.

   The underwriters do not expect to confirm sales of common stock to any
accounts over which they exercise discretionary authority.

   We, all of our directors and officers and stockholders holding an aggregate
of 6,857,815 shares of our common stock have agreed that, subject to certain
exceptions, for a period of 180 days from the date of this prospectus, without
the prior written consent of Bear, Stearns & Co. Inc., which may be waived, we
will not, directly or indirectly, issue, sell, offer or agree to sell, grant
any option for the sale of, pledge, make any short sale, establish an open "put
equivalent position" within the meaning of Rule 16a-1(h) under the Exchange Act
or otherwise dispose of any shares of our common stock or securities
convertible into, exercisable for or exchangeable for our common stock.

   The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by us. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

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

   Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for the common stock
will be determined by negotiations among us and the representatives of the
underwriters. Among the factors to be considered in those negotiations will be:

  .  Our results of operations in recent periods;

  .  Estimates of our prospects and the industry in which we compete;

  .  An assessment of our management;

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

  .  The prices of similar securities of generally comparable companies.

   We have applied to have our common stock approved for quotation on the
Nasdaq National Market under the symbol ASTR. However, there can be no
assurance that an active or orderly trading market will develop for the common
stock or that the common stock will trade in the public markets subsequent to
this offering at or above the initial offering price.

   In connection with the offering, certain persons participating in this
offering may purchase and sell shares of common stock in the open market. These
transactions may include short sales, stabilizing transactions and purchases to
cover positions created by short sales. Short sales involve the sale by the
underwriters of a greater number of shares than they are required to purchase
in this offering. Stabilizing transactions consist of certain bids or purchases
made for the purpose of preventing or retarding a decline in the market price
of the common stock while this offering is in progress. The underwriters also
may impose a penalty bid. This occurs when a particular underwriter repays to
the underwriters a portion of the underwriting discount received by it because
the representative has repurchased shares sold by or for the account of such
underwriter in stabilizing or short covering transactions.

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


   We estimate that the total expenses of the offering, excluding underwriting
discounts and commissions, will be approximately $1,100,000.

   In the ordinary course of business, certain of the underwriters and their
affiliates have provided, and may in the future provide, financial advisory and
investment banking services for us and our affiliates for customary fees. Legg
Mason Wood Walker, Incorporated acted as financial advisor to CBSI in
connection with the acquisition of CBSI by us and was paid a fee by CBSI of
$625,000 for their services plus expenses and was also given the right to
receive up to an additional $25,000 based on the achievement of certain
financial thresholds by CBSI.

                                 LEGAL MATTERS

   The validity of the shares of common stock offered by this prospectus will
be passed upon for us by Swidler Berlin Shereff Friedman, LLP, New York, New
York, and for the underwriters by Proskauer Rose LLP, New York, New York.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

  Overview

   On February 27, 1998, we acquired Pacer. The purchase price was
approximately $17 million, plus transaction-related expenses of approximately
$1.7 million. Of the total purchase price, approximately $7 million was paid in
cash to Pacer shareholders, with the balance paid by the issuance of
approximately 2,255,000 shares of our common stock. The merger has been
accounted for using the purchase method of accounting.

   On March 18, 1999, we acquired Computer Based Systems, Inc. for $26 million.
We did not acquire certain assets of CBSI that we believed were not related to
IT operations. $25 million of the purchase price was paid at the closing, with
the $1 million balance to be paid equally over five years. The transaction
costs are estimated to be $600,000. The purchase price is subject to
adjustment, based on CBSI's net worth on the closing date.

   Simultaneous with the CBSI closing, we entered into a $75 million secured
financing agreement comprised of $45 million in senior term loans and a $30
million revolving credit note. Expenses associated with the financing were
estimated to be $1.9 million. Proceeds from the financing agreement were used
to acquire CBSI and retire debt, and for working capital purposes. The senior
term loans are comprised of two tranches: Term A of $15 million with periodic
principal payments maturing in five years carrying a variable interest rate of
up to LIBOR plus 2.75% and Term B of $30 million with periodic payments
maturing in six years carrying a variable interest rate of LIBOR plus 3%.

   The Unaudited Pro Forma Condensed Consolidated Statement of Operations for
the year ended December 31, 1998 gives effect to the acquisitions of Pacer and
CBSI, including the financing of these acquisitions, as if they had occurred on
January 1, 1998. The Unaudited Pro Forma Condensed Statement of Operations
includes the historical results of operations of Pacer for the two months ended
February 28, 1998 and CBSI for the year ended December 31, 1998.

   The Unaudited Pro Forma Condensed Consolidated Balance Sheet gives effect to
the acquisition of CBSI as if it had occurred on December 31, 1998. The
following pro forma statements and the accompanying notes should be read in
conjunction with the historical financial statements of us, Pacer and CBSI and
notes thereto.

   The Unaudited Pro Forma Condensed Consolidated Financial Information is
intended for informational purposes only and is not necessarily indicative of
the future position or future results of operations of the consolidated company
after the acquisitions of Pacer and CBSI or of the financial position or
results of operations of the consolidated company that would have actually
occurred had the acquisitions of Pacer and CBSI been effected on January 1,
1998.

cash flows for the year ended February 28, 1997, the ten-month period ended
December 31, 1997 and the year ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of AverStar, Inc. at December 31, 1997 and 1998, and the consolidated results
of its operations and its cash flows for the year ended February 28, 1997, the
ten-month period ended December 31, 1997 and the year ended December 31, 1998,
in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies and Basis of Presentation

 Nature of Operations

   AverStar provides information technology, or IT, services and software
products for the mission-critical systems of civilian and defense agencies of
the United States government, as well as, large commercial companies.

 Basis of Presentation

   These consolidated financial statements include the accounts of AverStar,
Inc. (the Company) and its wholly owned subsidiaries, Apollo Holding, Inc.,
(Apollo), and Pacer Infotec, Inc. (Pacer). The Company was incorporated in
Delaware on February 4, 1998 for the purpose of combining the businesses of
Apollo and Pacer (see Note 2). All material intercompany balances and
transactions have been eliminated.

   Prior to February 4, 1998, the Company operated as Apollo, and the financial
statements included herein reflect the operations of Apollo for those periods
presented. On February 4, 1998 Averstar, Inc. (the Company) was formed by the
Apollo shareholders to acquire the business of Pacer (see Note 2) and to
combine the businesses of Apollo and Pacer. In connection with these
activities, the Company effected exchanges of stock with both Apollo and Pacer
shareholders at the time of the acquisition of Pacer. As described in Note 2,
the acquisition of Pacer has been accounted for as a purchase. The exchange by
Apollo shareholders of their shares in Apollo for their shares in Averstar was
accounted for as an exchange of shares by entities under common control in
accordance with paragraph 5 of APB #16. Accordingly, the Apollo operations
retained their historical cost basis. All share and per share data in these
financial statements and related footnotes have been adjusted to reflect such
exchanges.

   In 1997, the Board of Directors changed Apollo's fiscal year from the last
day of February to the last day of December. For the year ended December 31,
1998, the financial statements include twelve months of operations for Apollo
and ten months of operations for Pacer. For the period ended December 31, 1997,
the financial statements include ten months of operations for Apollo.

 Revenue Recognition

   Contracts with the Federal Government, or prime contractors of the Federal
Government, are cost reimbursable with a fee that is fixed or awarded based on
performance. Contracts with commercial enterprises and some Government
contracts are time and materials. Overhead and general and administrative costs
charged on U.S. Government contracts are generally subject to audit by the
Federal Government for allowability and proper charging under the contracts.
These contracts provide for periodic payments as the services are performed and
generally do not represent any unusual burden on the Company's liquidity. All
contracts with the Federal Government are subject to termination by the
customer. The Company has not suffered any adverse effects from the termination
of Government contracts in the past.

   The Company recognizes revenue on government and commercial contracts under
the percentage-of-completion method in accordance with Statement of Position
81-1, "Accounting for Performance of Construction-Type and Certain Production-
Type contracts." The percentage of completion is determined by relating the
costs incurred to date to the estimated total costs at completion. The
cumulative effects resulting from revisions of estimated total contract costs
and revenues are recorded in the period in which the facts requiring revision
become known. When a loss is anticipated on a contract, the full amount of the
anticipated loss is provided for when it becomes probable. The Company
sometimes recognizes revenue that is not billable to the customer at a given
balance sheet date. Such amounts are included in unbilled receivables.

   Revenues from standard software products are recognized upon shipment in
accordance with Statement of Position 97-2, "Software Revenue Recognition."
Revenues from maintenance agreements are deferred and amortized over the life
of the maintenance agreement. Per unit royalties earned from the license of
standard software products are recognized when received from the customer.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 Cash Equivalents

   The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents.

 Unbilled Receivables

   Unbilled receivables represent amounts earned on contracts in process and
retainage that are not billable at the balance sheet date. Such amounts
generally become billable upon completion of a specific phase of the contract,
documentation of approved contract modifications, completion of government
audit or upon customer acceptance, if the Company believes the acceptance
criteria present no risk to the Company. The Company estimates that all billed
receivables and 80% of unbilled receivables will be collected within one year.
The Company has not recognized significant revenue relating to customer claims
for amounts in excess of agreed upon contract prices. To the extent that
billings exceed costs incurred, plus fees or less losses, the difference is
recorded as unearned revenue.

 Property, Plant and Equipment

   Property, plant and equipment are stated at cost. The Company provides for
depreciation and amortization over estimated useful lives using the straight-
line method as follows:

         Asset Classification                  Estimated Useful Life

                                     of lease or estimated life of improvement
     Computer, equipment and
      furniture..................... 2-7 years
</TABLE>

 Stock Compensation

   The Company accounts for grants of stock options in accordance with the
provisions of APB Opinion No. 25, "Accounting for Stock Issued to Employees."
The Company has adopted the disclosure-only provision of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation." See
Note 9.

 Use of Estimates

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

 Impairment Evaluation

   The Company examines the carrying value of its long lived assets,
identifiable intangibles, and goodwill to determine whether there are any
impairment losses. If indicators of impairment were present in those assets,
and future undiscounted cash flows were not expected to be sufficient to
recover the assets' carrying amounts, an impairment loss would be charged to
expense in the period identified. No event has been identified that would
indicate an impairment of the value of long-lived assets, identifiable
intangibles, and goodwill recorded in the accompanying consolidated financial
statements.

<PAGE>

                                 AVERSTAR, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

 Concentration of Credit Risk

   Financial instruments which subject the Company to credit risk consist of
cash equivalents and accounts receivable. The risk with respect to cash
equivalents is minimized by the Company's policies in which investments are
placed with highly rated issuers with relatively short maturities. The risk
with respect to accounts receivable is minimized due to the fact that customer
accounts and unbilled receivables represent amounts earned under the Company's
contracts, which are principally with U.S. Government agencies.

 Fair Value of Financial Instruments

   The Company's cash equivalents, accounts receivable, long-term debt and
redeemable common stock are carried at cost, which approximates fair value.

 Reclassifications

   Certain reclassifications have been made to the 1997 financial statements to
conform to the 1998 basis of presentation.

 Earnings Per Share

   In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings Per Share," of SFAS 128, which was required to be adopted for fiscal
years ending after December 15, 1997. Earnings per share amounts for all
periods presented conform to the SFAS 128 requirements. See Note 11 for the
computation of basic and diluted earnings per share.

 Comprehensive Income

   In 1997, the Financial Accounting Standards Board issued Statement No. 130,
"Reporting Comprehensive Income," or SFAS 130, which was required to be adopted
for fiscal years beginning after December 15, 1997. This statement established
new rules for reporting and display of comprehensive income and its components.
The adoption of this Statement had no impact on the Company's financial
statements.

 Segments of an Enterprise

   In 1997, the Financial Accounting Standards Board issued statement No. 131,
"Disclosures About Segments of an Enterprise and Related Information," or SFAS
131, which was required to be adopted for fiscal years beginning after December
15, 1997. SFAS 131, superseded SFAS No. 14, "Financial Reporting for Segments
of a Business Enterprise." This statement changes the way public companies
report segment information in annual financial statements. SFAS 131 requires
public companies to report financial and descriptive information about their
operating segments in interim financial reports to shareholders as well. The
adoption of this Statement had no impact on the disclosures in the Company's
financial statements as the Company has one reportable segment from continuing
operations: the development and delivery of information technology products and
services. The U.S. Government and its prime aerospace, civil and defense
contractors accounted for approximately 88%, 80% and 90% of the Company's
revenues for the year ended February 28, 1997, the ten-month period ended
December 31, 1997 and the year ended December 31, 1998.

 Pending Accounting Pronouncements

   In 1998, the Accounting Standard Executive Committee issued Statement of
Position 98-5, "Reporting on the Costs of Start-up Activities," which must be
adopted for fiscal years beginning after December 15, 1998, and the Financial
Accounting Standards Board issued Statement No. 133, "Accounting for Derivative

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Investments and Hedging Activities," which must be adopted for fiscal years
beginning after June 15, 1999. The adoption of these statements is not expected
to have a material impact on AverStar.

Note 2. Acquisition

   On February 27, 1998, Pacer, a company providing software engineering
services primarily to government customers, was acquired for a purchase price
of approximately $17,000,000, plus transaction related expenses of
approximately $1,700,000. Of the total purchase price, approximately $7,000,000
was paid in cash to Pacer shareholders, with the balance paid by the issuance
of approximately 2,255,000 shares of Class F common stock issued by AverStar
and the fair value of options exchanged in the transaction; said shares and
options having a value of approximately $10,000,000. The acquisition has been
accounted for using the purchase method of accounting, whereby assets and
liabilities have been allocated based upon their respective fair values,
resulting in goodwill and other intangible assets of approximately $12 million.

   Unaudited pro forma revenue, net loss and loss per share shown below for the
ten month period ended December 31, 1997 and the year ended December 31, 1998
assumes the acquisition of Pacer occurred on March 1, 1997:

   On March 18, 1999, the Company acquired all of the outstanding shares of
Computer Based Systems, Inc. (CBSI) for $26,000,000. CBSI provides software
engineering services primarily to government customers. Of the total purchase
price, $25,000,000 was paid to the shareholders at the closing, with the
balance paid equally over five years. The transaction costs are estimated to be
$600,000. The acquisition was accounted for using the purchase method of
accounting, whereby assets and liabilities have been allocated based upon their
respective fair value, resulting in goodwill and other intangibles assets of
approximately $19,400,000 which will be amortized for periods not to exceed 20
years.

Note 3. Discontinued Operations

   In December 1998, the Board of Directors of AverStar, Inc. adopted a plan to
divest of its 66% interest in Intermetrics Entertainment Software, Inc.'s (IES)
operations, which developed software games, by distributing such interest to
AverStar shareholders.

   As part of the plan to dispose of IES, the Company converted $1.3 million of
contributed capital (representing capital contributed by the Company reduced by
cumulative operating losses) into an 8.5% term loan due on December 31, 2001.
In connection with this conversion, the Company recorded the term loan and
fully reserved the amount and also fully reserved a pre-existing term loan of
$400,000 because,

                                 AVERSTAR, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

based upon forecasted operating results for IES, the Company believes it is
uncollectible. This write-off is part of the loss on disposal of discontinued
operations described below. In addition, AverStar is obligated to provide on
demand financing of up to $2 million pursuant to an 8.5% revolving credit
agreement, unless IES has filed for bankruptcy, is in the process of
liquidation or the equivalent. Under the terms of the revolving credit
agreement, no new borrowings may occur subsequent to December 31, 1999 and
amounts borrowed are due on December 31, 2001. Based upon forecasted operating
results for IES, AverStar management believes it is probable that the full
amount available will be drawn by IES and, further, management does not believe
such amounts which will become due under the revolving credit agreement will be
recoverable and, therefore, has assigned no value to it in the accompanying
financial statements. The Company will, however, pursue collection efforts. Any
subsequent recovery of such amounts due under the term loans or the revolving
credit agreement all of which are due not later than December 31, 2001, and
currently represent a deferred gain of $3,700,000, will be reflected as a gain
from discontinued operations at the time of such recovery.

   The major components of the $3,900,000 loss from disposal of discontinued
operations are estimated operating losses through the disposal date of
$500,000, estimated remaining funding commitment of $1,500,000 pursuant to a
$2,000,000 revolving credit agreement estimated professional fees of $200,000
and write-offs of estimated non-recoverable term loans of $1,700,000.

   As of December 31, 1998, the liabilities of IES exceeded its assets by
$565,000, which is comprised of billed and unbilled receivables of $4,200,000,
other assets and equipment of $2,300,000, bank debt of $3,900,000, accrued
expenses of $1,500,000, and obligations to AverStar of approximately
$1,700,000. Included in the loss on disposal in 1998 is approximately $500,000
of operating losses from the date the Plan was adopted through the date of
divestiture, which occurred on March 18, 1999.

   In addition, interest of $293,000 was allocated to the loss from
discontinued operations based on the financing that was specifically attributed
to those operations.

   Revenues from discontinued operations were $7,232,000 for the year ended
December 31, 1998 and $1,928,000 for the period from August 9 through December
31, 1997.

Note 6. Benefit Plans

   The Company has a 401(k) profit-sharing plan that covers substantially all
employees and provides for a company matching contribution. As defined under
the Plan, employees are allowed to contribute the maximum established by law,
and the Company may match up to 4% of the employee's contribution. Expenses
relating to this Plan amounted to $402,000 for the year ended February 28,
1997, $784,000 for the ten-month period ended December 31, 1997 and $1,405,000
for the year ended December 31, 1998.

   The Company has a noncontributory defined contribution plan that covered
substantially all employees of Pacer prior to the acquisition described in Note
2. Substantially all of the contributions have been invested in the Company's
common stock. At December 31, 1998, the Plan is dormant and the Company did not
incur any expense related to the Plan in 1998.

Note 7. Borrowings

   At December 31, 1998, the Company had $24,333,000 of secured Senior Notes,
secured by substantially all of the Company's tangible and intangible assets,
and $5,000,000 of unsecured Subordinated Notes. The interest rate on the Senior
Notes of $7,833,000 was a variable rate based on the three-month London
Interbank Offered Rate (LIBOR) plus 3% (8.065% at December 31, 1998). The
interest rate on the Senior Bridge Notes of $16,500,000 was LIBOR plus 3% and
increased 0.5% each six months during the term. The interest rate on the
Subordinated Notes is fixed at 13% per annum. The Senior Notes contain
covenants and restrictions involving consolidated net worth, ratio of current
assets to current liabilities, fixed charge and interest coverage, limitations
on liens, restricted payments and investments, transactions with affiliates,
sale of assets, sale and leaseback transactions, and mergers and
consolidations.

   At December 31, 1998 the Company also had a secured Senior Revolving Credit
Agreement that provided for aggregate borrowings of $5,000,000 maturing on
August 31, 2001. The revolving credit facility was available to finance general
operating requirements. The outstanding borrowings under this facility were
$2,000,000 as of December 31, 1997 and $2,500,000 as of December 31, 1998.

   On March 18, 1999, simultaneous with the CBSI closing described in Note 2,
the Company entered into an agreement to provide up to $75,000,000 of secured
financing, based upon availability, comprised of $45,000,000 in Senior Term
Loans and a $30,000,000 revolving credit facility note. Expenses associated
with the financing are estimated to be $1,900,000. Proceeds from the financing
agreement were used to pay CBSI shareholders, retire existing debt, and provide
for working capital requirements. The Senior Term Loans comprise two tranches.
The Term A Note of $15,000,000 matures March 17, 2004 and carries a variable
interest rate of up to LIBOR plus 2.75%. The Term B Note of $30,000,000 matures
March 17, 2005 and carries a variable interest rate of LIBOR plus 3%. The
revolving facility note matures on March 17, 2004 and carries a variable
interest rate of LIBOR plus 2.75%. These agreements contain covenants and
restrictions pertaining to the maintenance of net worth and certain ratios
relating to operating results.

   At March 31, 1999, the Company had $44.8 million, $8.7 million and $5.0
million outstanding under the senior term loans, revolving credit facility note
and subordinated notes respectively. The interest paid on all borrowings was
$1,255,000 for the ten-month period ended December 31, 1997, $2,809,000 for the
year ended December 31, 1998 and $764,000 for the three months ended March 31,
1999.

   Certain Class F voting, redeemable shares serve as collateral on a note
receivable of approximately $850,000 issued to the Company by a former
employee. The note bears interest at 6.36% per annum with scheduled repayments
through May 2001. In the event the Class F shareholder presents certain shares
to the Company for redemption, the proceeds from such redemption are required
to be remitted to the Company in satisfaction of this note, which is included
in other assets in the accompanying balance sheet.

   In addition to the redemption features of the Class F--Voting shares, the
Company has also granted to certain management shareholders the right to have
the Company redeem approximately 1,749,000 shares of Class A-F stock at certain
amounts, as defined. The estimated fair value of such redemption at December
31, 1998 was $3,941,225. The redemption of such shares is limited in the first
five years by amounts stipulated in the Stockholder Agreements. The shares are
subject to redemption at a price and upon terms as defined in the Stockholder
Agreements. Upon the occurrence of certain events, including an initial public
offering, the redemption features for all classes of stock lapse.

   The Company holds Promissory Notes of $200,000 issued by certain employees
for the purchase of Class A Common Stock. The Notes, which are fully recourse
to the issuers and have been classified as a reduction of redeemable common
stock, bear interest at 7% per annum. Interest is payable semiannually or
annually, and the principal is scheduled for payment from March 2000 through
August 2005.

Note 9. Stock Options

   The Company has a Long Term Incentive Plan (the Plan) pursuant to which the
Company may grant Incentive Stock Options, Non-qualified Stock Options, Stock
Appreciation Rights, Restricted Stock, Deferred Stock, Stock Purchase Rights or
Other Stock-Based Awards.

   The maximum aggregate number of shares of Stock reserved and available for
distribution under the Plan shall be 3,349,447 shares of Stock, reduced by the
number of shares of Stock subject to being issued from time to time upon the
exercise of outstanding awards granted under the Plan. At December 31, 1998
there were 3,349,447 shares of stock reserved and available for distribution.

   The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation," and will continue to account for option grants to employees
under the Plan in accordance with APB No. 25, "Accounting for Stock Issued to
Employees." Adoption of SFAS No. 123 did not have a material impact on the
Company's financial statements and, accordingly, no pro forma net income has
been disclosed for the year ended February 28, 1997, the ten-month period ended
December 31, 1997 and the year ended December 31, 1998, for the compensation
expense of options grants which otherwise would be required under the
disclosure requirements of SFAS No. 123.

   The fair market value of each option grant is estimated on the date using
the Minimum Value option-pricing model with the following weighted-average
assumptions used for grants issued in the year ended February 28, 1997, the
ten-month period ended December 31, 1997 and the year ended December 31, 1998:

computation of diluted earnings per share because the options' exercise prices
were greater than the average market price of the common shares and, therefore,
the effect would be anti-dilutive. There were no shares of common stock
excluded in the computation of diluted earnings per share at February 28, 1997
and December 31, 1997.

                     December 31, 1996, 1997 and 1998

NOTE 1--Organization And Significant Accounting Policies

 (A) Organization

   Computer Based Systems, Inc. (CBSI) was incorporated in 1978 under the laws
of the Commonwealth of Virginia. The Company's primary business is providing
engineering, management and analytical services to principally civilian
agencies of the U.S. Government.

 (B) Revenue recognition

   Revenue from cost-type contracts is recognized as costs are incurred on the
basis of direct costs plus allowable indirect costs and an allocable portion of
a fixed fee.

   Revenue from fixed-price type contracts is recognized under the percentage-
of-completion method of accounting with costs and estimated profits included in
contract revenue as work is performed. If actual and estimated costs to
complete a contract indicate a loss, provision is made currently for the loss
anticipated on the contract.

   Revenue from time and materials contracts is recognized as costs are
incurred at amounts represented by the agreed-upon billing amounts.

   Revenue recognized on contracts for which billings have not been presented
to customers at year end, is included in the Accounts receivable--contracts
classification on the Balance Sheets as detailed in Note 2.

 (C) Property and equipment

   Property and equipment are recorded at cost. Depreciation and amortization
is provided using the straight-line method over the estimated useful lives of
the assets. The estimated lives used in determining depreciation and
amortization are:

<TABLE>
    <S>                                 <C>
    Office equipment and software...... 5 years
    Furniture and fixtures............. 7 years
    Vehicles........................... 5 years
    Tenant improvements................ shorter of term of lease or useful life
    Building........................... 39 years
</TABLE>

 (D) Income taxes

   Effective January 1, 1990, the Company elected S-Corporation status whereby
the taxable income of the Company, subject to certain restrictions and
elections, is taxed directly to the Company's shareholders. The Company
continues to be liable for tax on built-in gains existing at the date of the
election which are primarily deferred taxable income from the Company's use of
the cash basis of accounting for income tax purposes, net of available net
operating loss and investment tax credit carryforwards. Such tax is payable to
the extent the Company would have otherwise paid income taxes on a C
Corporation basis during the ten-year period following the election. A deferred
tax liability has been provided in the accompanying financial statements for
this liability. The liability is classified as current due to the uncertainty
as to when this liability might be required to be paid.

                     December 31, 1996, 1997 and 1998

NOTE 1--Organization And Significant Accounting Policies--(continued)

 (E) Cash and cash equivalents

   The Company maintains cash balances which may exceed Federally insured
limits. The Company does not believe that this results in any significant
credit risk.

   For purposes of the financial statement presentation, the Company considers
all highly liquid debt instruments with initial maturities of ninety days or
less to be cash equivalents.

   Beginning in 1998, the Company has a Money Management Zero Balance Account
(ZBA) arrangement for its checking account activity. Under this arrangement,
the bank automatically draws/repays the line of credit based upon the net daily
activity in the checking accounts and invests any excess cash balance
overnight. Therefore, checks not yet presented for payment are reflected on the
Balance Sheet as ZBA account balance which at December 31, 1998 was $2,758,759.

 (F) Estimates

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

 (G) Comprehensive income

   In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income.
This statement established standards for the reporting and display of
comprehensive income and its components in the financial statements. In
accordance with the provisions of this statement, the Company has included a
separate Statement of Other Comprehensive Income in the accompanying financial
statements. Comprehensive income for the years ended December 31, 1996 and 1997
has been presented for comparative purposes.

 (H) Reclassifications

   Certain 1996 amounts have been reclassified to conform to the 1997 and 1998
presentation.

NOTE 2--Accounts Receivable--Contracts

   The accounts receivable consist mainly of billed and unbilled recoverable
amounts under contracts in progress with governmental units, principally with
four agencies of the Federal Government. Unbilled receivables consist primarily
of award fees earned on cost-reimbursement contracts earned during the year.
The components of accounts receivable at December 31, 1997 and 1998 are as
follows:

   As of December 31, 1997, the aggregate unrealized loss on marketable
securities was $101,386 and the aggregate unrealized gain was $26,468 which
resulted in the net unrealized loss of $74,918 which has been reflected as a

   The Company maintains a qualified profit sharing plan with a 401(k) deferred
contribution option for all present and future employees that have reached 21

15% of gross salaries. There was no profit sharing contribution for 1996, 1997
and 1998.

   The participants in the 401(k) deferred contribution option may elect to
contribute from 1% to 17.5% of their gross annual earnings up to $7,000, as
indexed for inflation. The Company may, at its discretion, make a matching
contribution of each participants' contributions. Employees become fully vested

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                     December 31, 1996, 1997 and 1998


NOTE 9--Leases--(continued)

Company entered into an agreement to lease office furniture to one of its
tenants which resulted in income from furniture rental of $66,417 and $60,417
for the years ended December 31, 1997 and 1998, respectively.

   Certain leases have escalation clauses and rent for certain office space was
abated by a lessor for approximately four months. The Company has recorded rent
on a straight-line basis based upon the total of lease payments to be paid over
the life of the leases. The straight-line recognition of rent expense has
created a deferred rent payable which will be paid over the remaining life of
these leases.

NOTE 10--Contracts

   Billings under cost-based government contracts are calculated using
provisional rates that permit recovery of indirect costs. These rates are
subject to audit on an annual basis by the government agencies' cognizant audit
agency. The cost audit will result in the negotiation and determination of the
final indirect cost rates that the Company may use for the period(s) audited.
The final rates, if different from the provisionals, may create an additional
receivable or liability.

   As of December 31, 1998, the Company has final settlements on indirect rates
through December 31, 1995. The Company periodically reviews its cost estimates
and experience rates, and adjustments, if needed, are made and reflected in the
period in which the estimates are revised. In the opinion of management,
redetermination of any cost-based contracts will not have a material effect on
the Company's financial position or results of operations.

NOTE 11--Subsequent Event

   As of December 31, 1998, the Company had entered into a letter of intent for
the sale of the Company. On January 31, 1999, the Company signed an agreement
and Plan of Merger with the acquiring company.

NOTE 12--Restatement Of Stockholders' Equity

   During 1998, the Company corrected an error to the par value of its voting
and non-voting common stock. During 1996, the financial statements reflected a
par value of $.01 per share for voting and non-voting common stock. The error
has been corrected by restating the components of stockholders' equity as of
January 1, 1996 to reflect $1 par value of voting and non-voting common stock.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders of Pacer Infotec, Inc.

   We have audited the accompanying consolidated balance sheets of Pacer
Infotec, Inc. and subsidiaries (the Company) as of December 31, 1996 and 1997
and the related consolidated statements of operations, stockholders equity, and
cash flows for the years ended December 31, 1996 and 1997 and the period from
January 1, 1998 to February 28, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Pacer Infotec,
Inc. and subsidiaries at December 31, 1996 and 1997, and the consolidated
results of their operations and their cash flows for the years ended December
31, 1996 and 1997 and the period from January 1, 1998 to February 28, 1998 in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Significant Accounting Policies

Principles of Consolidation

   The consolidated financial statements of Pacer Infotec, Inc. (formerly Pacer
Systems, Inc.) and subsidiaries (collectively, the Company) include the
accounts of the Company and its wholly-owned subsidiaries, Computing
Applications Software Technology, Inc. (CAST), acquired in 1992, and Infotec
Development, Inc. (IDI), which was merged with Pacer Systems, Inc. in 1996 by
way of acquisition. In connection with this merger, the Company's name was
changed to Pacer Infotec, Inc. All significant intercompany transactions have
been eliminated in consolidation. On February 27, 1998, the Company merged with
Apollo Holding, Inc. (see Note 2).

Cash Equivalents

   The Company considers all highly liquid investments with maturities of three
months or less from the date acquired to be cash equivalents.

Inventory

   Inventory, principally electrical and mechanical components and assemblies,
is stated at the lower of cost or market. Cost is determined using the first-
in, first-out (FIFO) method.

Property and Equipment

   Property and equipment are valued at historical cost or fair value if
obtained in connection with an acquisition. Depreciation of office building,
furniture and equipment is provided for over the estimated useful lives of the
assets, which range from five to thirty years. Amortization of leasehold
improvements is provided for over the term of the lease or their estimated
useful lives, whichever is shorter. Depreciation and amortization are
calculated on the straight-line basis for financial reporting purposes.

Cost in Excess of Net Assets of Business Acquired

   This balance represents the excess of the value of shares issued and other
costs incurred over the fair value of the net assets acquired of IDI. The
excess cost is being amortized using the straight-line method over 20 years.

Impairment of Long-Lived Assets

   In 1996, the Company adopted Statement of Financial Accounting Standards
(SFAS) No. 121, "Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed Of." SFAS No. 121 requires recognition of impairment losses on long-
lived assets when indicators of impairment losses on long-lived assets are
present and future undiscounted cash flows are insufficient to support the
assets' recovery. Adoption of SFAS No. 121 had no material impact on the
Company's financial statements.

Revenue Recognition

   A major portion of the Company's sales consists of revenues earned from
long-term professional engineering service and other contracts, principally
with U.S. Government agencies. The Company recognizes revenue as services are
performed or the percentage-of-completion method based upon the terms of the
contracts. Sales of air data systems are recognized as revenue at the time of
shipment.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

1. Significant Accounting Policies--(continued)

Risks and Uncertainties

 Concentration of Credit Risk

   Financial instruments which subject the Company to credit risk consist of
cash equivalents and accounts receivable. The risk with respect to cash
equivalents is minimized by the Company's policies in which investments are
only placed with highly rated issuers with relatively short maturities. The
risk with respect to accounts receivable is minimized due to the fact that
customer accounts and unbilled receivables represent amounts earned under the
Company's contracts, which are principally with U.S. Government agencies.

 Estimates

   The preparation of the 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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Significant estimates and assumptions are required by
management in the area of determining contract completion. Significant
estimates and assumptions have also been made by management in connection with
the merger discussed in Note 2. Actual results could differ from those
estimates.

Income Taxes

   The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standard No. 109, "Accounting for Income Taxes." This
method requires income taxes to be recognized based on income taxes currently
payable and the change in deferred taxes during the year. Deferred taxes are
recognized based on the temporary differences between the financial statement
and tax bases of assets and liabilities at enacted tax rates as of the dates
the differences are expected to reverse.

Earnings per Share

   In 1997, the Company adopted Statement of Financial Accounting Standards
(SFAS) No. 128, "Earnings per Share." SFAS No. 128 establishes criteria for
calculating basic earnings per share in which the dilutive effect of stock
options is excluded, and requires restatement of all prior period earnings per
share data presented. Adoption of SFAS No. 128 did not have a material impact
on the Company's financial statements.

   Basic earnings per share is computed using the weighted-average number of
common shares outstanding during the year. Diluted earnings per share includes
the effect of all potentially dilutive securities.

Reclassification

   Certain amounts at December 31, 1996 have been reclassified to permit
comparison with December 31, 1997.

Stock-Based Compensation

   The Company accounts for stock option grants to employees in accordance with
APB Opinion No. 25, "Accounting for Stock Issued to Employees."

Accounting Pronouncements

   Effective January 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income", which is effective for all financial statements
beginning after December 15, 1997. Under SFAS No. 130, the

1. Significant Accounting Policies--(continued)

Company is required to report and display comprehensive income and its
components in a full set of general purpose financial statements and to
reclassify earlier periods provided for comparative purposes. For the period
from January 1, 1998 to February 28, 1998, net earnings and comprehensive
income are the same.

   In 1997, the Financial Accounting Standards Board issued statement No. 131,
"Disclosures About Segments of an Enterprise and Related Information," or SFAS
131, which was required to be adopted for fiscal years beginning after December
15, 1997, SFAS 131, superseded SFAS No. 14, "Financial Reporting for Segments
of a Business Enterprise." This statement changes the way public companies
report segment information in annual financial statements. SFAS 131 requires
public companies to report financial and descriptive information about their
operating segments in interim financial reports to shareholders as well. The
adoption of this Statement had no impact on the disclosures in the Company's
financial statements as the Company has once reportable segment.

2. Business Combination

   On June 28, 1996, Pacer Systems, Inc. (Pacer) and IDI entered into an
Agreement of Merger and Plan of Reorganization (Merger Agreement) in which each
share of IDI common stock was exchanged for 4.1856 shares of Pacer. In
accordance with the Merger Agreement, and subsequent modifications, 2,688,251
shares of stock were issued by Pacer and exchanged for all the outstanding
common stock of IDI. In connection with the merger, Pacer changed its name to
Pacer Infotec, Inc. The merger has been accounted for under the purchase method
and, accordingly, the fair value of the shares and costs including professional
fees and certain liabilities, principally related to severance arrangements,
incurred in connection with the merger have been allocated to the net assets of
IDI based upon their fair value. The excess of the cost over fair value of net
assets is being amortized over 20 years on a straight-line basis. The operating
results of IDI have been included in the Company's consolidated financial
statements from July 25, 1996, the effective date of the merger. As previously
discussed, management allocated the cost of the acquisition to the net assets
of IDI based on its estimate of their fair value. Significant estimates were
made with respect to the fair value of unbilled receivables recoverable under
certain contracts which are subject to final settlement with the U.S.
Government agencies. Although at the date of the merger, management believed
its estimates to be appropriate, the final resolution of actual amounts due in
connection with these contract settlements differed from the estimates. As a
result, the Company increased costs in excess of net assets during the year by
$857,651 to reflect the final resolution of these estimates.

   In connection with the merger, certain stockholders of IDI executed new
promissory notes representing principal and accrued interest owed to IDI on
notes entered into in previous years in exchange for cash. The promissory notes
bear interest at 6.3 6%, mature at various dates ranging from 1997 to 2001 and
are collateralized by shares of the Company owned by these stockholders.

   On February 27, 1998, Pacer Infotec, Inc. and Apollo Holding, Inc. merged to
form AverStar, Inc. (AverStar), a newly formed corporation. The merger was
consummated by the contribution of approximately 4.6 million shares of common
stock of Pacer Infotec, Inc. and all of the outstanding shares of Apollo
Holding, Inc. As a result, the Company's business and operations will be
combined into AverStar, Inc. In connection with the merger, AverStar provided
cash to the Company to reduce its bank debt (see Note 3). In addition, AverStar
will pay approximately $7 million to redeem the remaining 3.5 million
outstanding shares of Pacer Infotec, Inc. publicly registered common stock on
the London Stock Exchange. The Company terminated its listing on the London
Stock Exchange on February 27, 1998.

3. Financing Arrangements

   In July 1996, in connection with the acquisition discussed in Note 2, the
Company entered into a revolving credit agreement (Agreement) with its bank
which permits borrowings up to $12,000,000 based on specified

                                      F-45

levels of billed and unbilled accounts receivable on contracts in process. At
the date of the merger, approximately $11,000,000 of IDI debt was repaid from
$7,500,000 of proceeds from borrowings under the Agreement and the Company's
existing cash balances. Borrowings are due on demand and bear interest at the
bank's prime lending rate plus 1.75% (10% at December 31, 1997). Substantially
all of the Company's assets are secured as collateral under the Agreement.

   The Agreement as amended in January 1997, includes certain quarterly and
annual operating and net worth covenants. The Agreement expires on June 30,
1998. At December 31, 1996 and 1997, $7,500,000 and $4,300,000 were outstanding
under the Agreement.

   On February 27, 1998, the Company, in connection with its acquisition
disclosed in Note 2, canceled the Agreement by paying its outstanding line of
credit balance.

   Long-term debt consists of the following:

</TABLE>

   Future maturities of long-term debt are as follows: 1998--$207,240 and
1999--$200,000.

   The carrying value of the Company's debt approximates fair value. Interest
paid for the years ended December 31, 1996 and 1997 and the period from January
1, 1998 to February 28, 1998 approximates interest expense.

4. Stock Options

   The Company has an Incentive Stock Option Plan (the Plan). Under terms of
the Plan, as amended, options may be granted to key employees to purchase up to
3,000,000 shares of common stock at prices not less than fair market value at
date of grant. The options expire up to ten years from date of grant, or upon
termination of employment, and are exercisable in installments based on vesting
schedules approved by the Board of Directors.

   The Company has adopted the disclosure provisions only of Statement of
Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock Based-
Compensation," and will continue to account for option grants to employees
under the Plan in accordance with APB No. 25, "Accounting for Stock Issued to
Employees." Adoption of SFAS No. 123 would not have a material impact on the
Company's financial statements and, accordingly, no pro forma net income has
been disclosed for the years ended December 31, 1997 and for the period from
January 1, 1998 to February 28, 1998 and for the compensation expense of option
grants which otherwise would be required under the disclosure requirements of
SFAS No. 123.

   The options for 740,849 shares of the Company's common stock were issued in
exchange for all of the outstanding options of IDI at the merger date. The
number of shares and exercise prices were adjusted based upon the exchange
ratio of 4.1856 described in Note 2. At December 31, 1996, December 31, 1997
and February 28, 1998, options for the purchase of 947,482, 1,722,972 and
1,727,972 shares, respectively, were exercisable with weighted average exercise
prices of $.93, $1.61 and $1.45, respectively. Exercise prices for options
outstanding as of February 28, 1998 ranged from $0.53 to $2.08. The weighted
average remaining contractual life of options outstanding at February 28, 1998
is 6.67.

5. Retirement Plans

Defined Contribution Plan

   The Company has a 401(k) profit-sharing plan which covers substantially all
employees and provides for a Company matching contribution. As defined under
the plan, employees are allowed to contribute the maximum established by law,
and the Company may match up to 4% of the employee's compensation. The
Company's expense relating to this plan amounted to $289,975 for the year ended
December 31, 1996, $499,983 for the year ended December 31, 1997 and $96,679
for the period January 1, 1998 to February 28, 1998.

Employee Stock Bonus Plan

   The Company has a noncontributory defined contribution plan which covers
substantially all employees and provides for an annual discretionary
contribution by the Company as determined by the Board of Directors based on
the Company's performance. The contribution is allocated among participating
employees in proportion to each participant's basic annual salary, as defined
in the plan. Substantially all of the Company's contributions will be invested
in the Company's common stock. The Company recognized $132,000 for the year
ended December 31, 1996 and $157,004 of expense for the year ended December 31,
1997 and did not recognize any expense for the period from January 1, 1998 to
February 28, 1998 related to the plan.

   In connection with the merger described in Note 2, the Company assumed a net
deferred tax liability, the most significant component of which related to the
change in 1993 by IDI from the cash to the accrual method of reporting taxable
income. The effect of this change has been included in taxable income ratably
over tax reporting periods beginning in 1993 and ending February 28, 1998. In
addition, due to significant losses of IDI incurred prior to the merger, the
Company was entitled to refundable income taxes of approximately $1,533,000 as
of December 31, 1996.

7. Income Taxes--(continued)

   These refundable income taxes have been included in the accompanying 1996
balance sheet net of federal and state taxes otherwise payable by the Company.
In addition, in 1997, as a result of the final resolution of amounts due under
certain IDI contracts assumed as of the acquisition, the Company recognized a
deferred tax asset of $787,200 in connection with the final adjustment of costs
in excess of net assets of IDI acquired.

   Significant components of the provision for income taxes are as follows:

   The Company's tax provision for the period from January 1, 1998 to February
28, 1998 exceeds the statutory rate due to the amortization of the excess of
costs over net assets acquired, which are not deductible for income tax
purposes.

   The 1997 effective income tax rate is higher than the expected statutory
rate due to amortization of the excess of costs over net assets acquired and
merger-related costs (see Note 8) which are not deductible for income tax
reporting purposes.

   The Company made payments of approximately $571,000 for the year ended
December 31, 1996, $1,295,000 for the year ended December 31, 1997 and did not
make any income tax payments from January 1, 1998 to February 28, 1998

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

1. Nature of Business and Summary of Significant Accounting Policies

   Looking Glass Technologies, Inc. (the Company) was incorporated in Delaware
on June 29, 1992. The Company designs, develops and publishes interactive
entertainment software. The Company sells its products to distributors
primarily in North America and the United Kingdom and its principal market is
the consumer market. The Company also licenses to other leading industry
publishers the right to publish and distribute the Company's software in
exchange for product development fees and future royalties.

   Effective August 9, 1997 the company contributed all its assets, liabilities
and operations to a newly formed entity, Intermetrics Entertainment Software
LLC (IES), and the shareholders of the Company received approximately a 34%
interest in IES.

   A summary of the Company's significant accounting policies follows:

Fixed Assets

   Fixed assets are stated at cost and depreciated using the straight-line
method over the related estimated useful lives. Maintenance and repair costs
are expensed as incurred.

Revenue Recognition

   Revenues from product sales are recognized upon shipment, net of allowances
for estimated returns and price protection, provided that no significant vendor
obligations remain and collection of the related receivable is probable.

   Nonrefundable advances on future royalties pursuant to software development
agreements with publishers are recognized as revenue as work is performed and
milestones defined in the related agreements are attained. The publishers are
entitled to set off all payments made to the Company during development of the
software against initial royalty payments due to the Company. Such right of set
off is conditioned upon the successful development and commercialization of the
software. Royalties in excess of payments made to the Company during
development of the software are recognized as revenue when earned based upon
product shipments from the publisher, net of allowances for returns and price
protection, as and when reported to the Company by the respective publishers.
Payments received under licensing agreements are initially recorded as deferred
revenue and recognized as revenue when earned based upon product shipments to
licensees.

Research and Development and Software Development Costs

   Costs incurred in the research and development of the Company's products
through the establishment of technological feasibility, as defined by Statement
of Financial Accounting Standards No. 86, Accounting for the Costs of Computer
Software to be Sold, Leases, or Otherwise Marketed, are expensed as incurred.
Development costs incurred thereafter and until the products are first
available for release have not been material and have therefore been expensed
as incurred.

Advertising

   Advertising costs are expensed as incurred. Advertising expense for the year
ended March 31, 1997 and for the period from April 1, 1997 through August 8,
1997 were $420,000 and $225,000, respectively.

Concentration of Credit Risk and Significant Customers

   At March 31, 1997 and August 8, 1997 the Company maintained cash balances in
certain bank accounts in excess of federally insured limits. All such accounts
are maintained in a highly rated financial institution. Accordingly, these
accounts bear minimal credit and market risk.

<PAGE>


                     LOOKING GLASS TECHNOLOGIES, INC.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   At March 31, 1997 $295,000 of the Company's accounts receivable was due from
one customer.

   Two customers accounted for 57% of the Company's total revenues during the
year ended March 31, 1997. During the period from April 1, 1997 through August
8, 1997, one customer accounted for 60% of the Company's total revenues.

Accounting Estimates

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

Accounting for Stock-Based Compensation

   In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation. The Company has adopted this standard through disclosure only in
the accompanying financial statements.

2. Income Taxes

   The Company has gross deferred tax assets of approximately $868,000 at March
31, 1997 and August 8, 1997. Gross deferred tax assets consist of federal and
state net operating loss carryforwards, research and development credit
carryforwards and temporary differences resulting from certain transactions
recognized in different periods for financial reporting and income tax
purposes. The Company has no deferred tax liabilities at March 31, 1997 and
August 8, 1997. The Company has provided a valuation allowance for the full
amount of the deferred tax assets at March 31, 1997 and August 8, 1997 since
realization of these future benefits is not sufficiently assured.

   At March 31, 1997, the Company has federal and state net operating loss
carryforwards of approximately $8,336,000 and $7,832,000, respectively, which
expire at various dates through 2011. At March 31, 1997, the Company also has
federal and state research and development tax credit carryforwards of
approximately $144,000 and $199,000, respectively, which expire at various
dates through 2011.

   Under the Internal Revenue Code, certain substantial changes in the
Company's ownership may limit the amount of net operating loss and tax credit
carryforwards that can be utilized to offset future taxable income or tax
liability.

3. Stockholders' Equity

Issuance of Preferred Stock

   Series A preferred stock consists of 825,000 shares of Series A-1 preferred
stock, issued for net proceeds of $36,770, and 825,000 shares of Series A-2
preferred stock, issued for net proceeds of $36,770. The Series A-1 preferred
stock and the Series A-2 preferred stock differ only as to voting rights, as
defined in the amended and restated certificate of incorporation. The 2,280,000
shares of Series B preferred stock were issued at a price of $1.67 per share
for aggregate consideration of $3,800,000. On August 10, 1995, the Company
issued 995,139 shares of Series C preferred stock at a price of $4.01 per share
for gross proceeds of $3,990,000.

                     LOOKING GLASS TECHNOLOGIES, INC.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   Each share of Series A, Series B and Series C preferred stock is convertible
into common stock at the option of the holder as a conversion price per share
defined in the amended and restated certificate of incorporation, or
automatically upon the earlier of (I) a vote of the holders of a least two-
thirds of each series of the outstanding preferred shares or (ii) the closing
of a public offering of the Company's common stock at a price of at least $4.33
per share and with aggregate net proceeds to the Company in excess of
$15,000,000. At March 31, 1997 and August 8, 1997, the Company has reserved a
total of 4,925,139 shares of common stock for the conversion of the outstanding
Series A, Series B and Series C preferred stock.

   Stockholders of Series A, Series B, and Series C preferred stock are
entitled to one vote for each share of common stock into which the Series A,
Series B and Series C preferred stock is convertible.

   The holders of the Series A, Series B and Series C preferred stock are
entitled to receive dividends when and if declared by the Board of Directors
and are noncumulative. Through August 8, 1997, no dividends have been declared
or paid.

Warrants

   In connection with the issuance of Series C preferred stock in August 1995,
the Company issued a warrant for the purchase of up to 150,000 shares of Series
C preferred stock (Preferred Stock Warrant). The Preferred Stock Warrant is
exercisable at a price of $4.01 per share and expired on December 31, 1996. The
Company also issued a warrant for the purchase of up to 150,000 shares of
common stock (Common Stock Warrant), exercisable upon the effective date of an
initial public offering (IPO) at the IPO price per common share. The Common
Stock Warrant expires twenty four months after the IPO date. The values
ascribed to the preferred and common stock warrants were not significant. The
Company has reserved 150,000 shares of preferred stock and 150,000 shares of
common stock for issuance upon exercise of the warrants.

4. 1992 Stock Plan

   At August 8, 1997 Looking Glass Technologies, Inc. had a stock compensation
plan which is described below. Looking Glass Technologies, Inc. applies APB
Opinion 25 related Interpretations in accounting for its plan. Looking Glass
Technologies, Inc. has adopted the disclosure-only provision of SFAS 123.
Accordingly, no compensation cost has been recognized for its stock
compensation plans. Adoption of SFAS 123 would not have a material impact on
the Company's financial statements and accordingly no pro forma net income has
been disclosed for the year ended March 31, 1997 and the period from April 1,
1997 through August 8, 1997. The weighted-average grant date fair value of
options granted is not material.

   The effects on pro forma net income of expensing the estimated fair market
value of stock options are not necessarily representative of effects on
reported net income for future years due to such factors as the vesting period
of the stock options and the potential issuance of additional stock options in
future years. Additionally, because SFAS 123 is applicable only to options
granted subsequent to December 31, 1994, its pro forma effect will not be fully
reflected until 1999 or 2000.

Fixed stock compensation plans:

   The 1992 Stock Plan (the "1992 Plan") provides for the grant of incentive
stock options, nonqualified stock options and stock purchase rights for the
purchase of up to an aggregate of 2,700,000 shares of the Company's common
stock by employees, consultants and directors. The Board of Directors is
responsible for administration of the 1992 Plan and, accordingly, determines
the term, exercise price, number of shares and vesting period of each option.
Options granted under the 1992 Plan generally expire ten years from the date of
the grant.

<PAGE>


                     LOOKING GLASS TECHNOLOGIES, INC.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   Incentive stock options may be granted to an employee at an exercise price
per share of not less fair value per common share on the date of grant (not
less than 110% of the fair value in the case of holders of more than 10% of
Company's voting stock). Non qualified stock options may be granted to
employees, consultants and directors at an exercise price per share not less
than 85% of the fair value per common share on the date of the grant (110% of
the fair value in the case of holders of more than 10% of the Company's voting
stock).

   The fair market value of each option grant is estimated on the date of the
grant using the Minimum Value option-pricing model with the following weighted
average assumptions used for grants in the year ended March 31, 1997 and the
period April 1, 1997 through August 8, 1997:

Item 14. Indemnification of Directors and Officers.

   Our amended and restated bylaws that will become effective upon the closing
of this offering provide that we will indemnify our directors and executive
officers to the fullest extent permitted by Delaware law and may indemnify our
other officers, employees and other agents to the fullest extent permitted by
Delaware law.

   In addition, our second amended restated certificate of incorporation that
will become effective upon the closing of this offering provides that, to the
fullest extent permitted by Delaware law, our directors will not be personally
liable to us or our stockholders for monetary damages for any breach of
fiduciary duty as directors. This provision of the restated certificate of
incorporation does not eliminate the directors' duty of care. In appropriate
circumstances, equitable remedies such as an injunction or other forms of non-
monetary relief are available under Delaware law. This provision also does not
affect the directors' responsibilities under any other laws, such as the
federal securities laws.

   Each director will continue to be subject to liability for:

  .  Breach of a director's duty of loyalty to us and our stockholders;

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

  .  Unlawful payments of dividends or unlawful stock repurchases or
     redemptions; and

  .  Any transaction from which a director derived an improper personal
     benefit.

   We have purchased liability insurance for our directors and executive
officers.

   There is no pending litigation or proceeding involving any of our directors
or officers as to which indemnification is being sought. We are not aware of
any pending or threatened litigation that may result in a claim for
indemnification.

  .  4,611,211 shares of common stock in exchange for all of the issued and
     outstanding capital stock of Apollo Holding, Inc., the parent of
     Intermetrics; and

  .  2,255,224 shares of common stock, and paid $7 million in exchange for
     all of the issued and outstanding capital stock of Pacer Infotec, Inc.

   The issuance and sale of these shares of common stock was exempt from
registration pursuant to Section 4(2) of the Securities Act.

   Options. In connection with the combination of the business of Intermetrics
and Pacer and our acquisition of Pacer, we assumed all outstanding stock
options of each of Intermetrics and Pacer in reliance upon exemptions from
registration pursuant to either Section 4(2) of the Securities Act, or (ii)
Rule 701 under the Securities Act. In addition, we have granted and may grant
stock options to employees in reliance upon exemptions from registration
pursuant to Rule 701 under the Securities Act. From March 1, 1998 to March 31,
1999, we have granted options under our 1998 Long Term Incentive Plan to
purchase 190,000 shares of common stock at an exercise price per share of
$8.00.

Item 17. Undertakings.

   The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in those
denominations and registered in those 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 may be permitted to directors, officers and controlling persons of the
registrant pursuant to provisions described in Item 14 or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission this indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against those liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
this indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of that 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 this offering of these securities at that time shall
  be deemed to be the initial bona fide offering thereof.

Dear Sirs:

          AverStar, Inc., a corporation organized and existing under the laws of
the State of Delaware (the "Company"), proposes, subject to the terms and
conditions stated herein, to issue and sell to the several underwriters named in
Schedule I hereto (the "Underwriters") an aggregate of 4,000,000 shares (the
"Firm Shares") of its common stock, par value $.001 per share (the "Common
Stock"), and, for the sole purpose of covering over-allotments in connection
with the sale of the Firm Shares, at the option of the Underwriters, up to an
additional 600,000 shares (the "Additional Shares") of Common Stock. The Firm
Shares and any Additional Shares purchased by the Underwriters are referred to
herein as the "Shares." The Shares are more fully described in the Registration
Statement referred to below.

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

               (a)  The Company has filed with the Securities and Exchange
     Commission (the "Commission") a registration statement on Form S-1 (No.
     333-78517), and may have filed an amendment or amendments thereto, for the
     registration of the Shares under the Securities Act of 1933, as amended
     (the "Act"). Such registration statement, including the prospectus,
     financial statements and schedules, exhibits and all other documents filed
     as a part thereof, as amended at the time of effectiveness of the
     registration statement, including any information deemed to be a part
     thereof as of the time of effectiveness pursuant to paragraph (b) of Rule
     430A or Rule 434 of the Rules and Regulations of the Commission under the
     Act (the "Regulations"), is herein called the "Registration Statement" and
     the prospectus, in the form first filed with the Commission pursuant to
     Rule 424(b) of the Regulations or filed as part of the Registration
     Statement at the time of effectiveness if no Rule 424(b) or Rule 434 filing
     is required, is herein called the "Prospectus." The term "preliminary
     prospectus" as used herein means a preliminary prospectus as described in
     Rule 430 of the Regulations.
<PAGE>

          (b)  At the time of the effectiveness of the Registration Statement or
     the effectiveness of any post-effective amendment to the Registration
     Statement, when the Prospectus is first filed with the Commission pursuant
     to Rule 424(b) or Rule 434 of the Regulations, when any supplement to or
     amendment of the Prospectus is filed with the Commission and at the Closing
     Date and the Additional Closing Date, if any (as hereinafter respectively
     defined), the Registration Statement and the Prospectus and any amendments
     thereof and supplements thereto complied or will comply in all material
     respects with the applicable provisions of the Act and the Regulations and
     do not or will not contain an untrue statement of a material fact and do
     not or will not omit to state any material fact required to be stated
     therein or necessary in order to make the statements therein (i) in the
     case of the Registration Statement, not misleading and (ii) in the case of
     the Prospectus, in light of the circumstances under which they were made,
     not misleading. When the preliminary prospectus relating to the Shares was
     first filed with the Commission (whether filed as part of the registration
     statement for the registration of the Shares or any amendment thereto or
     pursuant to Rule 424(a) of the Regulations) and when any amendment thereof
     or supplement thereto was first filed with the Commission, such preliminary
     prospectus and any amendments thereof and supplements thereto complied in
     all material respects with the applicable provisions of the Act and the
     Regulations and did not contain an untrue statement of a material fact and
     did not omit to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading. No representation
     and warranty is made in this subsection (b), however, with respect to any
     information contained in or omitted from the Registration Statement or the
     Prospectus or any related preliminary prospectus or any amendment thereof
     or supplement thereto in reliance upon and in conformity with information
     furnished in writing to the Company by or on behalf of any Underwriter
     through the Representatives as herein stated expressly for use in
     connection with the preparation thereof. If Rule 434 is used, the Company
     will comply with the requirements of Rule 434.

          (c)  Each of Ernst & Young LLP, Aronson, Fetridge & Weigle and Grant
     Thornton LLP, who have certified certain financial statements and
     supporting schedules included in the Registration Statement, are
     independent public accountants as required by the Act and the Regulations.

          (d)  Subsequent to the respective dates as of which information is
     given in the Registration Statement and the Prospectus, except as set forth
     in the Registration Statement and the Prospectus, there has been no
     material adverse change or any development involving a prospective material
     adverse change in the business, prospects, properties, operations,
     condition (financial or other) or results of operations of the Company and
     its subsidiaries taken as a whole, whether or not arising from transactions
     in the ordinary course of business ("Material Adverse Effect"), and since
     the date of the latest balance sheet presented in the Registration
     Statement and the Prospectus, neither the Company nor any of its
     subsidiaries has incurred or undertaken any liabilities or obligations,
     direct or contingent, whether or not arising from transactions in the
     ordinary course of business, which are material to the Company and its
     subsidiaries taken as a whole, except for liabilities or obligations that
     are reflected in the Registration Statement and the Prospectus.

                                       2
<PAGE>

          (e)  This Agreement and the transactions contemplated herein have been
     duly and validly authorized by the Company and this Agreement has been duly
     and validly executed and delivered by the Company.

          (f)  Neither the Company nor any of its subsidiaries is (i) in
     violation of its respective certificate of incorporation or by-laws (or
     other organizational documents), (ii) in violation of any law, ordinance or
     regulation applicable to it, its business as now being conducted and as
     described in the Registration Statement or the ownership of its assets,
     except such violations that would not have a Material Adverse Effect, or
     (iii) in default in the performance of any obligation, agreement or
     condition contained in any agreement, instrument, franchise, license,
     permit, judgment, order or decree to which the Company or any of its
     subsidiaries is a party or by which it or any of its subsidiaries or their
     respective property or assets is bound, except such defaults that would not
     have a Material Adverse Effect.

          (g)  The execution, delivery and performance of this Agreement and the
     consummation of the transactions contemplated hereby do not and will not
     (i) conflict with or result in a breach of any of the terms and provisions
     of, or constitute a default (or an event which with notice or lapse of
     time, or both, would constitute a default) under, or result in the creation
     or imposition of any lien, charge or encumbrance upon any property or
     assets of the Company or any of its subsidiaries pursuant to, any
     agreement, instrument, franchise, license or permit to which the Company or
     any of its subsidiaries is a party or by which any of such corporations or
     their respective properties or assets may be bound or (ii) violate or
     conflict with any provision of applicable law or the certificate of
     incorporation or by-laws (or other organizational documents) of the Company
     or any of its subsidiaries or any judgment, decree, order, statute, rule or
     regulation of any court or any public, governmental or regulatory agency or
     body having jurisdiction over the Company or any of its subsidiaries or any
     of their respective properties or assets. No consent, approval,
     authorization, order, registration, filing, qualification, license or
     permit of or with any court or any public, governmental or regulatory
     agency or body having jurisdiction over the Company or any of its
     subsidiaries or any of their respective properties or assets is required
     for the execution, delivery and performance of this Agreement or the
     consummation of the transactions contemplated hereby, including the
     issuance, sale and delivery of the Shares to be issued, sold and delivered
     by the Company hereunder, except the registration under the Act of the
     Shares and such consents, approvals, authorizations, orders, registrations,
     filings, qualifications, licenses and permits as may be required under
     state securities or Blue Sky laws in connection with the purchase and
     distribution of the Shares by the Underwriters.

          (h)  All of the outstanding shares of Common Stock are duly and
     validly authorized and issued, fully paid and nonassessable and were not
     issued and are not now in violation of or subject to any preemptive or
     similar rights. The Shares, when issued, delivered and sold in accordance
     with this Agreement, will be duly and validly issued and outstanding, fully
     paid and nonassessable, and will not have been issued in violation of or be
     subject to any preemptive or similar rights. The Company had, at March 31,
     1999, an authorized and outstanding capitalization as set forth in the
     Registration Statement and

                                       3

     the Prospectus. The Common Stock, the Firm Shares and the Additional Shares
     conform to the descriptions thereof contained in the Registration Statement
     and the Prospectus.

          (i)  Each of the Company and its subsidiaries has been duly organized
     and is validly existing as a corporation in good standing under the laws of
     its jurisdiction of incorporation. Each of the Company and its subsidiaries
     is duly qualified and in good standing as a foreign corporation in each
     jurisdiction in which the character or location of its properties (owned,
     leased or licensed) or the nature or conduct of its business makes such
     qualification necessary, except for those failures to be so qualified or in
     good standing which will not, individually or in the aggregate, have a
     Material Adverse Effect. Each of the Company and its subsidiaries has all
     requisite power and authority, and all necessary consents, approvals,
     authorizations, orders, registrations, qualifications, licenses and permits
     of and from all public, regulatory or governmental agencies and bodies, to
     own, lease and operate its properties and conduct its business as now being
     conducted and as described in the Registration Statement and the
     Prospectus, and no such consent, approval, authorization, order,
     registration, qualification, license or permit contains a materially
     burdensome restriction not adequately disclosed in the Registration
     Statement and the Prospectus. Each of the Company and its subsidiaries has
     complied with all Federal, state, local and foreign laws, ordinances,
     regulations and orders applicable to it, its business as now being
     conducted and as described in the Registration Statement or the ownership
     of its assets, except where the failure to be in compliance would not have
     a Material Adverse Effect. All of the issued shares of capital stock of
     each subsidiary of the Company have been duly and validly authorized and
     issued, are fully paid and nonassessable and were not issued in violation
     of any preemptive or similar rights and are owned directly or indirectly by
     the Company, free and clear of any lien, encumbrance, claim, security
     interest, restriction on transfer, stockholder's agreement, voting trust or
     other defect of title whatsoever, except as described in the Registration
     Statement and the Prospectus.

          (j)  Except as described in the Prospectus, there is no litigation or
     governmental proceeding to which the Company or any of its subsidiaries is
     a party or to which any property of the Company or any of its subsidiaries
     is subject or which is pending or, to the knowledge of the Company,
     contemplated against the Company or any of its subsidiaries which might
     result in a Material Adverse Effect or which is required to be disclosed in
     the Registration Statement and the Prospectus, and there are no statutes,
     regulations, contracts or other documents that are required to be described
     in the Registration Statement or the Prospectus or to be filed as exhibits
     to the Registration Statement that are not described or filed as required.

          (k)  The Company has not taken and will not take, directly or
     indirectly, any action designed to cause or result in, or which constitutes
     or which might reasonably be expected to constitute, the stabilization or
     manipulation of the price of the shares of Common Stock to facilitate the
     sale or resale of the Shares.

          (l)  The financial statements, including the notes thereto, and
     supporting schedules included in the Registration Statement and the
     Prospectus present fairly the consolidated financial position of the
     Company, Apollo Holding, Inc. ("Apollo"), Pacer

                                       4

     Infotec, Inc. ("Pacer," Apollo and Pacer being collectively referred to
     herein as the "Predecessor Companies") and Computer Based Systems, Inc., as
     of the dates indicated and the results of their operations and changes in
     cash flows for the periods specified; except as otherwise stated in the
     Registration Statement, said financial statements have been prepared in
     conformity with generally accepted accounting principles applied on a
     consistent basis; and the supporting schedules included in the Registration
     Statement present fairly the information required to be stated therein; and
     the pro forma financial information included in the Registration Statement
     and the Prospectus has been prepared in accordance with the Commission's
     rules and guidelines with respect to pro forma financial statements and the
     assumptions used in the preparation thereof are, in the Company's opinion,
     reasonable; and the other financial and statistical information and data
     included in the Registration Statement and the Prospectus is, in all
     material respects, accurately presented and prepared on a basis consistent
     with such financial statements and the books and records of the Company.

          (m)  Except as described in the Prospectus, no holder of securities of
     the Company has any rights to the registration of securities of the Company
     because of the filing of the Registration Statement or otherwise in
     connection with the sale of the Shares contemplated hereby.

          (n)  The Company is not, and upon consummation of the transactions
     contemplated hereby will not be, subject to registration as an "investment
     company" under the Investment Company Act of 1940.

     issuance on the Nasdaq National Market System.

          (p)  No labor dispute with the employees of the Company or any of its

     the Company is not aware of any existing, threatened or imminent labor
     dispute or disturbance by the employees of any of its principal customers,
     suppliers, contractors or providers of outsourced services that might have
     a Material Adverse Effect.

          (q)  Except as described in the Registration Statement and the
     Prospectus, the Company and its subsidiaries own or possess valid and
     enforceable licenses or other rights to use all inventions, patents, patent
     applications, trademarks, service marks, trade names, copyrights,
     technology, know-how (including trade secrets and other unpatented and/or
     unpatentable proprietary or confidential information, systems or
     procedures), proprietary techniques (including processes and substances)
     and other intellectual property rights necessary to conduct the business
     now conducted or presently contemplated to be conducted by the Company and
     its subsidiaries, taken as a whole, as described in the Registration
     Statement and the Prospectus ("Intellectual Property"), subject to such
     exceptions as would not have a Material Adverse Effect. Other than as
     described in the Registration Statement and the Prospectus: (i) there are
     no third parties who have any rights in the Intellectual Property that
     could preclude the Company or its subsidiaries from conducting its business
     as currently conducted or as presently contemplated to be conducted as
     described in the Registration Statement and the

                                       5
<PAGE>

     Prospectus; (ii) there are no pending or, to the Company's knowledge,
     threatened actions, suits, proceedings, investigations or claims by others
     challenging the rights of the Company, its subsidiaries or (if the
     Intellectual Property is licensed) the licensor thereof in any Intellectual
     Property owned or licensed to the Company or its subsidiaries; (iii) the
     Company, its subsidiaries and (if the Intellectual Property is licensed) to
     the Company's knowledge the licensor thereof has not infringed, or received
     any notice of infringement of or conflict with, any rights of others with
     respect to the Intellectual Property; and (iv) there is no dispute between
     it or any licensor with respect to any Intellectual Property, subject, with
     respect to any of (i), (ii), (iii) or (iv), to such exceptions,
     individually or in the aggregate, as would not have a Material Adverse
     Effect.

          (r)  The Company and its subsidiaries (i) are in compliance with any
     and all applicable foreign, federal, state and local laws and regulations
     relating to the protection of human health and safety, the environment or
     hazardous or toxic substances or wastes, pollutants or contaminants
     ("Environmental Laws"), (ii) have received all permits, licenses or other
     approvals required of them under applicable Environmental Laws to conduct
     their respective businesses and (iii) are in compliance with all terms and
     conditions of any such permit, license or approval, except where such
     noncompliance with Environmental Laws, failure to receive required permits,
     licenses or other approvals or failure to comply with the terms and
     conditions of such permits, licenses or approvals would not, singly or in
     the aggregate, have a Material Adverse Effect.

          (s)  There are no costs or liabilities associated with Environmental
     Laws (including, without limitation, any capital or operating expenditures
     required for clean-up, closure of properties or compliance with
     Environmental Laws or any permit, license or approval, any related
     constraints on operating activities and any potential liabilities to third
     parties) which would, singly or in the aggregate, have a Material Adverse
     Effect.

          (t)  The Company and its subsidiaries have good and marketable title
     in fee simple to all real property and good and marketable title to all
     personal property owned by them which is material to the business of the
     Company and its subsidiaries, in each case free and clear of all liens,
     encumbrances and defects except such as are described in the Prospectus or
     such as do not materially affect the value of such property and do not
     interfere with the use made and proposed to be made of such property by the
     Company and its subsidiaries; and any real property and buildings held
     under lease by the Company and its subsidiaries are held by them under
     valid, subsisting and enforceable leases with such exceptions as are not
     material and do not interfere with the use made and proposed to be made of
     such property and buildings by the Company and its subsidiaries, in each
     case except as described in or contemplated by the Prospectus.

          (u)  The Company and each of its subsidiaries are insured by insurers
     of recognized financial responsibility against such losses and risks and in
     such amounts as are prudent and customary in the businesses in 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

                                       6
<PAGE>

     coverage expires or to obtain similar coverage from similar insurers as may
     be necessary to continue its business at a cost that would not result in a
     Material Adverse Effect.

          (v)  The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general

     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets

     amendments or supplements thereto subsequent to the date of this
     Agreement), the Company has not sold, issued or distributed any shares of
     Common Stock during the six-month period preceding the date hereof,
     including any sales pursuant to Rule 144A under, or Regulation D or S of,
     the Act, other than shares issued pursuant to employee benefit plans,
     qualified stock option plans or other employee compensation plans or
     pursuant to outstanding options, rights or warrants.

          (x)  No relationship, direct or indirect, exists between or among the
     Company or any of its subsidiaries on the one hand, and the directors,
     officers, stockholders, customers, suppliers or providers of outsourced
     services of the Company or any of its subsidiaries on the other hand, which
     is required by the Act to be described in the Registration Statement and
     the Prospectus which is not so described.

     2.  Purchase, Sale and Delivery of the Shares.
         -----------------------------------------

          (a)  On the basis of the representations, warranties, covenants and
     agreements herein contained, but subject to the terms and conditions herein
     set forth, the Company agrees to sell to the Underwriters and the
     Underwriters, severally and not jointly, agree to purchase from the
     Company, at a purchase price per share of $__________, the number of Firm
     Shares set forth opposite the respective names of the Underwriters in
     Schedule I hereto plus any additional number of Shares which such
     Underwriter may become obligated to purchase pursuant to the provisions of
     Section 9 hereof.

          (b)  Payment of the purchase price for, and delivery of certificates
     for, the Shares shall be made at the offices of Proskauer Rose LLP, 1585
     Broadway, New York, New York 10036, or at such other place as shall be
     agreed upon by the Representatives and the Company, at 9:00 A.M. on the
     third or fourth business day (as permitted under Rule 15c6-1 under the
     Exchange Act) (unless postponed in accordance with the provisions of
     Section 9 hereof), following the date of the effectiveness of the
     Registration Statement (or, if the Company has elected to rely upon Rule
     430A of the Regulations, the third or fourth business day (as permitted
     under Rule 15c6-1 under the Exchange Act) after the determination of the
     initial public offering price of the Shares), such time and date of payment
     and delivery being herein called the "Closing Date". Payment shall be made
     to

                                       7
<PAGE>

     the Company by certified or official bank check or checks drawn in federal
     funds or similar same day funds payable to the order of the Company or by
     wire transfer in same day funds at the option of the Underwriters, against
     delivery to the Representatives for the respective accounts of the
     Underwriters of certificates for the Shares to be purchased by them.
     Certificates for the Shares shall be registered in such name or names and
     in such authorized denominations as the Representatives may request in
     writing at least two full business days prior to the Closing Date. The
     Company will permit the Representatives to examine and package such
     certificates for delivery at least one full business day prior to the
     Closing Date.

          (c) In addition, the Company hereby grants to the Underwriters options
     to purchase up to an aggregate of 600,000 Additional Shares at the same
     purchase price per share to be paid by the Underwriters to the Company for
     the Firm Shares as set forth in this Section 2, for the sole purpose of
     covering over-allotments in the sale of Firm Shares by the Underwriters.
     Such options may be exercised at any time and from time to time, in whole
     or in part, on or before the thirtieth day following the date of the
     Prospectus, by written notice by the Representatives to the Company. Each
     such notice shall set forth the aggregate number of Additional Shares as to
     which an option is being exercised and the date and time, as reasonably
     determined by the Representatives, when the Additional Shares are to be
     delivered (each such date and time being herein sometimes referred to as
     the "Additional Closing Date"); provided, however, that no Additional
                                     --------  -------
     Closing Date shall be earlier than the Closing Date or earlier than the
     second full business day after the date on which the option shall have been
     exercised nor later than the eighth full business day after the date on
     which the option shall have been exercised (unless such time and date are
     postponed in accordance with the provisions of Section 9 hereof).
     Certificates for Additional Shares shall be registered in such name or
     names and in such authorized denominations as the Representatives may
     request in writing at least two full business days prior to the applicable
     Additional Closing Date.  The Company will permit the Representatives to
     examine and package such certificates for delivery at least one full
     business day prior to the applicable Additional Closing Date.

          The number of Additional Shares to be sold to each Underwriter on an
Additional Closing Date shall be the number which bears the same ratio to the
aggregate number of Additional Shares being purchased on such Additional Closing
Date as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I hereto (or such number increased as set forth in
Section 9 hereof) bears to 4,000,000, subject, however, to such adjustments to
eliminate any fractional shares as the Representatives in their sole discretion
shall make.

          Payment for the Additional Shares shall be made by certified or
official bank check or checks drawn in federal funds or similar same day funds,
payable to the order of the Company, or by wire transfer in same day funds at
the option of the Underwriters at the offices of Proskauer Rose LLP, 1585
Broadway, New York, New York 10036, or such other location as may be mutually
acceptable, upon delivery of the certificates for the Additional Shares to the
Representatives for the respective accounts of the Underwriters.

     the Underwriters subject to the terms of this Agreement, the applicable
     rules, regulations and interpretations of the National Association of
     Securities Dealers, Inc. and all other applicable laws, rules and
     regulations, provided, however, that under no circumstances will Bear,
                  --------  -------
     Stearns & Co. Inc. or any other Underwriter be liable to the Company or to
     any of the Directed Shares Purchasers for any action taken or omitted in
     good faith in connection with transactions effected with regard to the
     Directed Shares Purchasers. To the extent that such Directed Shares are not
     orally confirmed for purchase by such persons by the end of the first day
     after the date of this Agreement, such Directed Shares will be offered to
     the public as part of the underwritten offering contemplated hereby.

     4. Covenants of the Company.  The Company covenants and agrees with the
        ------------------------
Underwriters that:

          (a) If the Registration Statement has not yet been declared effective,
     the Company will use its best efforts to cause the Registration Statement
     and any amendments thereto to become effective as promptly as possible, and
     if Rule 430A is used or the filing of the Prospectus is otherwise required
     under Rule 424(b) or Rule 434, the Company will file the Prospectus
     (properly completed if Rule 430A has been used) pursuant to Rule 424(b) or
     Rule 434 within the prescribed time period and will provide evidence
     satisfactory to you of such timely filing. If the Company elects to rely on
     Rule 434, the Company will prepare and file a term sheet that complies with
     the requirements of Rule 434.

          The Company will notify you immediately (and, if requested by you will
     confirm such notice in writing) (i) when the Registration Statement and any
     amendments thereto become effective, (ii) of any request by the Commission
     for any amendment of or supplement to the Registration Statement or the
     Prospectus or for any additional information, (iii) of the mailing or the
     delivery to the Commission for filing of any amendment of or supplement to
     the Registration Statement or the Prospectus, (iv) of the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or any post-effective amendment thereto or of the
     initiation, or the threatening, of any proceedings therefor, (v) of the
     receipt of any comments from the Commission, and (vi) of the receipt by the
     Company of any notification with respect to the suspension of the
     qualification of the Shares for sale in any jurisdiction or the initiation
     or threatening of any proceeding for that purpose. If the Commission shall
     propose or enter a stop order at any time, the Company will use its best
     effort to prevent the issuance of any such stop order and, if issued, to
     obtain the lifting of such order as soon as possible. The Company will not
     file any amendment to the Registration Statement or any amendment of or
     supplement to the Prospectus (including the

                                       9
<PAGE>

     prospectus required to be filed pursuant to Rule 424(b) or Rule 434) that
     differs from the prospectus on file at the time of the effectiveness of the
     Registration Statement before or after the effective date of the
     Registration Statement to which the Representatives shall reasonably object
     in writing after being timely furnished in advance a copy thereof.

          (b) If at any time when a prospectus relating to the Shares is
     required to be delivered under the Act any event shall have occurred as a
     result of which the Prospectus as then amended or supplemented would, in
     the judgment of the Representatives or the Company, include an untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein, in light of the circumstances under which they were
     made, not misleading, or if it shall be necessary, in the judgment of the
     Representatives or the Company, at any time to amend or supplement the
     Prospectus or the Registration Statement to comply with the Act or the
     Regulations, the Company will notify you promptly and prepare and file with
     the Commission an appropriate amendment or supplement (in form and
     substance satisfactory to the Representatives) which will correct the
     statement or omission and will use its best efforts to have any amendment
     to the Registration Statement declared effective as soon as possible.

          (c) The Company will promptly deliver to you one signed copy of the
     Registration Statement, including exhibits and all amendments thereto, and
     the Company will promptly deliver to each of the Underwriters such number
     of copies of any preliminary prospectus, the Prospectus, the Registration
     Statement and all amendments of and supplements to such documents, if any,
     as the Representatives may reasonably request.

          (d) The Company will endeavor in good faith, in cooperation with you,
     at or prior to the time of effectiveness of the Registration Statement, to
     qualify the Shares for offering and sale under the securities laws relating
     to the offering or sale of the Shares of such jurisdictions as the
     Representatives may designate and to maintain such qualification in effect
     for so long as required for the distribution thereof; except that in no
     event shall the Company be obligated in connection therewith to qualify as
     a foreign corporation or to execute a general consent to service of
     process.

          (e) The Company will make generally available (within the meaning of
     Section 11(a) of the Act) to its security holders and to you as soon as
     practicable, but not later than 45 days after the end of its fiscal quarter
     in which the first anniversary date of the effective date of the
     Registration Statement occurs, an earnings statement (in form complying
     with the provisions of Rule 158 of the Regulations) covering a period of at
     least twelve consecutive months beginning after the effective date of the
     Registration Statement.

          (f) During the period of 180 days from the date of the Prospectus, the
     Company will not, without the prior written consent of Bear, Stearns & Co.
     Inc. (i) issue, sell, offer or agree to sell, grant any option for the sale
     of, pledge, make any short sale, establish an open "put equivalent
     position" within the meaning of Rule 16a-1(h) under the Securities Exchange
     Act of 1934, as amended), or otherwise dispose of, any Common Stock (or any
     securities convertible into, exercisable for or exchangeable for Common
     Stock) of the

                                       10
<PAGE>

     Company or of any of its subsidiaries or (ii) enter into any swap,
     derivative transaction or other arrangement that transfers to another, in
     whole or in part, any of the economic consequences of ownership of the
     Common Stock, whether any such transaction described in clause (i) or (ii)
     above is to be settled by delivery of Common Stock or such other
     securities, in cash or otherwise, provided that the foregoing shall not
     apply to (A) the Shares to be sold hereunder, and (B) the issuance by the
     Company of shares of Common Stock upon the exercise of any option or
     warrant outstanding on the date hereof and disclosed in the Prospectus; and
     the Company will obtain the undertaking of each of its officers and
     directors and such of its stockholders as have been heretofore designated
     by the Representatives and listed on Schedule II attached hereto not to
     engage in any of the aforementioned transactions on their own behalf.

          (g) During a period of three years from the effective date of the
     Registration Statement, the Company will furnish to you copies of (i) all
     reports to its stockholders and (ii) all reports, financial statements and
     proxy or information statements filed by the Company with the Commission or
     any national securities exchange.

          (h) The Company will apply the proceeds from the sale of the Shares as
     set forth under "Use of Proceeds" in the Prospectus.

          (i) The Company will use its best efforts to cause the Shares to
     continue to qualify for inclusion in the Nasdaq National Market System.

          (j) The Company will use its best efforts to ensure that the Directed
     Shares are restricted as required by the National Association of Securities
     Dealers, Inc. or the National Association of Securities Dealers, Inc. rules
     from sale, transfer, assignment, pledge or hypothecation for a period of
     three (3) months following the date of this Agreement. The Underwriters
     will notify the Company as to which persons will need to be so restricted.
     At the request of the Underwriters, the Company will direct the transfer
     agent to place a stop transfer restriction upon such securities for such a
     period of time. Should the Company release, or seek to release, from such
     restrictions any of the Directed Shares, the Company agrees to reimburse
     the Underwriters for any reasonable expenses (including, without
     limitation, legal expenses) they incur in connection with such release.

     5. Payment of Expenses.  Whether or not the transactions contemplated in
        -------------------
this Agreement are consummated or this Agreement is terminated, the Company
hereby agrees to pay all costs and expenses incident to the performance of the
obligations of the Company hereunder, including those in connection with (i)

Statement, as originally filed and all amendments thereof (including all
exhibits thereto), any preliminary prospectus, the Prospectus and any amendments

Company's accountants and counsel), the underwriting documents (including this
Agreement and the Agreement Among Underwriters) and all other documents related
to the public offering of the Shares (including those supplied to the
Underwriters in quantities as hereinabove stated), (ii) the issuance, transfer

     be disclosed in the Registration Statement and the Prospectus which has not
     been properly disclosed therein and there are no statutes, regulations,
     contracts or other documents that are required to be described in the
     Registration Statement or the Prospectus or to be filed as exhibits to the
     Registration Statement that are not described or filed as required.

          (vi)  The execution, delivery and performance of this Agreement and
     the consummation of the transactions contemplated hereby by the Company do
     not and will not (A) conflict with or result in a breach of any of the
     terms and provisions of, or constitute a default (or an event which with
     notice or lapse of time, or both, would constitute a default) under, or

<PAGE>

     Adverse Effect, or (B) violate or conflict with any provision of applicable
     law or the certificate of incorporation or by-laws (or other organizational
     documents) of the Company or any of its subsidiaries, or, to the knowledge
     of such counsel, any judgment, decree, order, statute, rule or regulation
     of any court or any public, governmental or regulatory agency or body
     having jurisdiction over the Company or any of its subsidiaries or any of
     their respective properties or assets. No consent, approval, authorization,
     order, registration, filing, qualification, license or permit of or with
     any court or any public, governmental, or regulatory agency or body having
     jurisdiction over the Company or any of its subsidiaries or any of their

     need express no opinion) and (2) such as have been made or obtained under
     the Act.

          (vii)  The statements (A) in the Prospectus under the captions "Risk
     Factors--Most of our revenues are derived from contracts with agencies of
     the United States government, and uncertainties in government contracts

     "Management--Employment Severance and Other Agreements with Management,""--
     Executive Officers and Directors," "--1998 Long Term Incentive Plan,"
     "Description of Securities" and "Shares Eligible for Future Sale" and (B)
     in the Registration Statement in Items 14 and 15, in each case insofar as
     such statements constitute summaries of the legal matters, documents or
     proceedings referred to therein, fairly present the information called for
     with respect to such legal matters, documents and proceedings and fairly
     summarize the matters referred to therein.

          (viii) The Company is not, and upon consummation of the transactions
     contemplated hereby, will not be, an "investment company" as such term is
     defined in the Investment Company Act of 1940, as amended.

          (ix)   The Registration Statement and the Prospectus and any
     amendments thereof or supplements thereto (other than the financial
     statements and schedules and other financial data included therein, as to
     which no opinion need be rendered) comply as to form in all material
     respects with the requirements of the Act and the Regulations.

          (x)    The Registration Statement is effective under the Act, and, to
     the knowledge of such counsel, no stop order suspending the effectiveness
     of the Registration Statement or any post-effective amendment thereof has
     been issued and no proceedings therefor have been initiated or threatened
     by the Commission and all filings required by Rule 424(b) of the
     Regulations have been made.

          (xi)   To such counsel's knowledge, no holder of any security of the
     Company has any right, not effectively satisfied or waived, to require
     inclusion of

                                       14
<PAGE>

          shares of Common Stock or any other security of the Company in the
          Registration Statement.

          In addition, such opinion shall also contain a statement that such
counsel has participated in conferences with officers and representatives of the
Company, representatives of the independent public accountants for the Company
and the Underwriters at which the contents of the Registration Statement and the
Prospectus and related matters were discussed and, no facts have come to the
attention of such counsel which would lead such counsel to believe that either
the Registration Statement at the time it became effective (including the
information deemed to be part of the Registration Statement at the time of
effectiveness pursuant to Rule 430A(b) or Rule 434, if applicable), or any
amendment thereof made prior to the Closing Date as of the date of such
amendment, contained an untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus as of its date (or any
amendment thereof or supplement thereto made prior to the Closing Date as of the
date of such amendment or supplement) and as of the Closing Date contained or
contains an untrue statement of a material fact or omitted or omits to state any
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading (it being understood that such counsel need express no belief or
opinion with respect to the financial statements and schedules and other
financial data included therein).

          In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States, the
General Corporation Law of the State of Delaware, the laws of the State of New
York and jurisdictions in which they are admitted, to the extent such counsel
deems proper and to the extent specified in such opinion, if at all, upon an
opinion or opinions (in form and substance reasonably satisfactory to
Underwriters' Counsel) of other counsel reasonably acceptable to Underwriters'
Counsel, familiar with the applicable laws; and (B) as to matters of fact, to
the extent they deem proper, on certificates of responsible officers of the
Company and certificates or other written statements of officers of departments
of various jurisdictions having custody of documents respecting the corporate
existence or good standing of the Company and its subsidiaries, provided that
copies of any such statements or certificates shall be delivered to
Underwriters' Counsel. The opinion of such counsel for the Company shall state
that the opinion of any such other counsel is in form satisfactory to such
counsel and, in their opinion, you and they are justified in relying thereon.


          The opinion of Swidler Berlin Shereff Friedman, LLP described in this
Section 6(b) shall be rendered to the Underwriters at the request of the Company
and shall so state therein.

          (c) All proceedings taken in connection with the sale of the Firm
     Shares and the Additional Shares as herein contemplated shall be
     satisfactory in form and substance to you and to Underwriters' Counsel, and
     the Underwriters shall have received from said Underwriters' Counsel a
     favorable opinion, dated as of the Closing Date with respect to the
     issuance and sale of the Shares, the Registration Statement and the
     Prospectus and such other related matters as the Representatives may
     reasonably require, and the Company shall have furnished to Underwriters'
     Counsel such documents as they request for the purpose of enabling them to
     pass upon such matters.

                                       15

          (d) At the Closing Date, you shall have received a certificate of the
     Chief Executive Officer and Chief Financial Officer of the Company, dated
     the Closing Date, to the effect that (i) the condition set forth in
     subsection (a) of this Section 6 has been satisfied, (ii) as of the date
     hereof and as of the Closing Date, the representations and warranties of
     the Company set forth in Section 1 hereof are accurate, (iii) as of the
     Closing Date, the obligations of the Company to be performed hereunder on
     or prior thereto have been duly performed and (iv) subsequent to the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, the Company and its subsidiaries have not
     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 material adverse change, in
     the business, prospects, properties, operations, condition (financial or
     otherwise) or results of operations of the Company and its subsidiaries
     taken as a whole, except in each case as described in or contemplated by
     the Prospectus.

          (e) At the time this Agreement is executed and at the Closing Date,
     you shall have received a letter, from Ernst & Young LLP, independent
     public accountants for the Company and the Predecessor Companies, dated,
     respectively, as of the date of this Agreement and as of the Closing Date
     addressed to the Underwriters and in form and substance satisfactory to the
     Representatives, to the effect that: (i) they are independent certified
     public accountants with respect to the Company and the Predecessor
     Companies within the meaning of the Act and the Regulations and stating
     that the answer to Item 10 of the Registration Statement is correct insofar
     as it relates to them; (ii) stating that, in their opinion, the financial
     statements and schedules of the Company and the Predecessor Companies
     included in the Registration Statement and the Prospectus and covered by
     their opinion therein comply as to form in all material respects with the
     applicable accounting requirements of the Act and the applicable published
     rules and regulations of the Commission thereunder; (iii) on the basis of
     procedures consisting of a reading of the latest available unaudited
     interim consolidated financial statements of the Company, and its
     subsidiaries, a reading of the minutes of meetings and consents of the
     stockholders and boards of directors of the Company and its subsidiaries
     and the committees of such boards subsequent to December 31, 1998,
     inquiries of officers and other employees of the Company and its
     subsidiaries who have responsibility for financial and accounting matters
     of the Company and its subsidiaries with respect to transactions and events

     inquiries to a date not more than five days (three days in the case of the
     letter delivered on the Closing Date) prior to the date of such letter,
     nothing has come to their attention that would cause them to believe that:
     (A) the unaudited consolidated financial statements and schedules of the
     Company presented in the Registration Statement and the Prospectus do not
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the applicable published rules and regulations
     of the Commission thereunder or that such unaudited consolidated financial
     statements are not fairly presented in conformity with generally accepted
     accounting principles applied on a basis substantially consistent with that
     of the audited consolidated financial statements of the Company included in
     the Registration Statement and the Prospectus; (B) with respect to the
     period subsequent to

                                       16
<PAGE>

     [ ], 1999, there were, as of the date of the most recent available monthly
     consolidated financial statements of the Company and its subsidiaries, if
     any, and as of a specified date not more than five days (three days in the
     case of the letter delivered on the Closing Date) prior to the date of such
     letter, any changes in the capital stock or long-term indebtedness of the
     Company or any decrease in the net current assets or stockholders' equity
     of the Company, in each case as compared with the amounts shown in the most
     recent balance sheet presented in the Registration Statement and the
     Prospectus, except for changes or decreases which the Registration
     Statement and the Prospectus disclose have occurred or may occur or which
     are set forth in such letter or (C) that during the period from [ ], 1999
     to the date of the most recent available monthly consolidated financial
     statements of the Company and its subsidiaries, if any, and to a specified
     date not more than five days (three days in the case of the letter
     delivered on the Closing Date) prior to the date of such letter, there was
     (1) any decrease, as compared with the corresponding period in the prior
     fiscal year, in total revenues, or any increase, as compared with the
     corresponding period in the prior fiscal year, in operating loss or the
     total or per share net loss or (2) any decrease, as compared with the
     corresponding period in the prior fiscal quarter, in revenues, except in
     any such case for decreases or increases which the Registration Statement
     and the Prospectus disclose have occurred or may occur or which are set
     forth in such letter; (iv) nothing has come to their attention that would
     cause them to believe that the pro forma financial information included in
     the Registration Statement do not comply 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 financial information; and (v) stating
     that they have compared specific dollar amounts, numbers of shares,
     percentages of revenues and earnings, and other financial information
     pertaining to the Company and its subsidiaries set forth in the
     Registration Statement and the Prospectus, which have been specified by you
     prior to the date of this Agreement, to the extent that such amounts,
     numbers, percentages, and information may be derived from the general
     accounting and financial records of the Company and its subsidiaries or
     from schedules furnished by the Company, and excluding any questions
     requiring an interpretation by legal counsel, with the results obtained
     from the application of specified readings, inquiries, and other
     appropriate procedures specified by you set forth in such letter, and found
     them to be in agreement.

          (f) Prior to the Closing Date, the Company shall have furnished to you
     such further information, certificates and documents as you may reasonably
     request.

          (g) You have shall received from each person who is a director or
     officer of the Company or such stockholder as have been heretofore
     designated by the Representatives and listed on Schedule II hereto an
     agreement to the effect that such person will not, directly or indirectly,

     for a period of 180 days after the date of the Prospectus.

          (h) At the Closing Date, the Shares shall have been approved for
     quotation on the Nasdaq National Market System.

     paid in settlement of any claim or litigation), joint or several, to which
     they or any of them may become subject under the Act, the Exchange Act or
     otherwise, insofar as such losses, liabilities, claims, damages or expenses
     (or actions in respect thereof) arise out of or are based upon any untrue
     statement or alleged untrue statement of a material fact contained in the
     registration statement for the registration of the Shares, as originally
     filed or any amendment thereof, or any related preliminary prospectus or
     the Prospectus, or in any supplement thereto or amendment thereof, or arise
     out of or are based upon the omission or alleged omission to state therein
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading; provided, however, that the Company will
                                        --------  -------
     not be liable in any such case to the extent but only to the extent that
     any such loss, liability, claim, damage or expense arises out of or is
     based upon any such untrue statement or alleged untrue statement or
     omission or alleged omission made therein in reliance upon and in
     conformity with written information furnished to the Company by or on
     behalf of any Underwriter through the Representatives expressly for use
     therein.  This indemnity agreement will be in addition to any liability
     which the Company may otherwise have including under this Agreement.

                                       18
<PAGE>

          (b) Each Underwriter severally, and not jointly, agrees to indemnify
     and hold harmless the Company, each of the directors of the Company, each
     of the officers of the Company who shall have signed the Registration
     Statement, and each other person, if any, who controls the Company within
     the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act,
     against any losses, liabilities, claims, damages and expenses whatsoever as
     incurred (including but not limited to attorneys' fees and any and all
     expenses whatsoever incurred in investigating, preparing or defending
     against any litigation, commenced or threatened, or any claim whatsoever,
     and any and all amounts paid in settlement of any claim or litigation),
     jointly or several, to which they or any of them may become subject under
     the Act, the Exchange Act or otherwise, insofar as such losses,
     liabilities, claims, damages or expenses (or actions in respect thereof)
     arise out of or are based upon any untrue statement or alleged untrue
     statement of a material fact contained in the registration statement for
     the registration of the Shares, as originally filed or any amendment
     thereof, or any related preliminary prospectus or the Prospectus, or in any
     amendment thereof or supplement thereto, or arise out of or are based upon
     the omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that any
     such loss, liability, claim, damage or expense arises out of or is based
     upon any such untrue statement or alleged untrue statement or omission or
     alleged omission made therein in reliance upon and in conformity with
     written information furnished to the Company by or on behalf of any
     Underwriter through the Representatives expressly for use therein;
     provided, however, that in no case shall any Underwriter be liable or
     responsible for any amount in excess of the underwriting discount
     applicable to the Shares purchased by such Underwriter hereunder. This
     indemnity will be in addition to any liability which any Underwriter may
     otherwise have including under this Agreement. The Company acknowledges
     that the statements set forth in the fifth, seventh, eleventh and twelfth
     paragraphs under the caption "Underwriting" in the Prospectus constitute
     the only information furnished in writing by or on behalf of any
     Underwriter expressly for use in the Registration Statement relating to the
     Shares as originally filed or in any amendment thereof, any related
     preliminary prospectus or the Prospectus or in any amendment thereof or
     supplement thereto, as the case may be.

          (c) In connection with the offer and sale of the Directed Shares, the
     Company agrees, promptly upon a request in writing, to indemnify and hold
     harmless the Underwriters from and against any and all losses, liabilities,
     claims, damages and expenses incurred by them as a result of the failure of
     the Directed Shares Purchasers to pay for and accept delivery of the
     Directed Shares which, by the end of the day following the date of this
     Agreement, were subject to a properly confirmed agreement to purchase such
     Directed Shares.

          (d) Promptly after receipt by an indemnified party under subsection
     (a) or (b) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under such subsection, notify each party
     against whom indemnification is to be sought in writing of the commencement
     thereof (but the failure so to notify an indemnifying party shall not
     relieve it from any liability which it may have under this Section 7). In
     case any such

                                       19
<PAGE>

     action is brought against any indemnified party, and it notifies an
     indemnifying party of the commencement thereof, the indemnifying party will
     be entitled to participate therein, and to the extent it may elect by
     written notice delivered to the indemnified party promptly after receiving
     the aforesaid notice from such indemnified party, to assume the defense
     thereof with counsel satisfactory to such indemnified party.
     Notwithstanding the foregoing, the indemnified party or parties shall have
     the right to employ its or their own counsel in any such case, but the fees
     and expenses of such counsel shall be at the expense of such indemnified
     party or parties unless (i) the employment of such counsel shall have been
     authorized in writing by one of the indemnifying parties in connection with
     the defense of such action, (ii) the indemnifying parties shall not have
     retained counsel to have charge of the defense of such action within a
     reasonable time after notice of commencement of the action, or (iii) such
     indemnified party or parties shall have reasonably concluded that there may
     be defenses available to it or them which are different from or additional
     to those available to one or all of the indemnifying parties (in which case
     the indemnifying parties shall not have the right to direct the defense of
     such action on behalf of the indemnified party or parties), in any of which
     events such fees and expenses shall be borne by the indemnifying parties.
     Anything in this subsection to the contrary notwithstanding, an
     indemnifying party shall not be liable for any settlement of any claim or
     action effected without its written consent; provided, however, that such
                                                  --------  ---------
     consent was not unreasonably withheld.

     8.  Contribution.  In order to provide for contribution in circumstances in
         ------------
which the indemnification provided for in Section 7 hereof is for any reason
held to be unavailable from any indemnifying party or is insufficient to hold
harmless a party indemnified thereunder, the Company and the Underwriters shall
contribute to the aggregate losses, claims, damages, liabilities and expenses of
the nature contemplated by such indemnification provision (including any
investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claims
asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Company any contribution received by
the Company from persons, other than the Underwriters, who may also be liable
for contribution, including persons who control the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the
Company who signed the Registration Statement and directors of the Company) as
incurred to which the Company and one or more of the Underwriters may be
subject, in such proportions as is appropriate to reflect the relative benefits
received by the Company and the Underwriters from the offering of the Shares or,
if such allocation is not permitted by applicable law or indemnification is not
available as a result of the indemnifying party not having received notice as
provided in Section 7 hereof, in such proportion as is appropriate to reflect
not only the relative benefits referred to above but also the relative fault of
the Company and the Underwriters in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations.  The relative benefits received
by the Company and the Underwriters shall be deemed to be in the same proportion
as (x) the total proceeds from the offering (net of underwriting discounts and
commissions but before deducting expenses) received by the Company and (y) the
underwriting discounts and commissions received by the Underwriters,
respectively, in each case as set forth in the table on the cover page of the
Prospectus.  The relative fault of the Company and of the Underwriters shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material

                                       20
<PAGE>

fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 8
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above. Notwithstanding
the provisions of this Section 8, (i) in no case shall any Underwriter be liable
or responsible for any amount in excess of the underwriting discount applicable
to the Shares purchased by such Underwriter hereunder, and (ii) 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. Notwithstanding the provisions of this Section 8
and the preceding sentence, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. For purposes of this Section 8, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act shall have the same rights to contribution as such
Underwriter, and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who shall have signed the Registration Statement and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to clauses (i) and (ii) of this Section 8. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties,
notify each party or parties from whom contribution may be sought, but the
omission to so notify such party or parties shall not relieve the party or
parties from whom contribution may be sought from any obligation it or they may
have under this Section 8 or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without its consent;
provided, however, that such consent was not unreasonably withheld.
- --------  -------

     9.   Default by an Underwriter.
          -------------------------

          (a) If any Underwriter or Underwriters shall default in its or their
     obligation to purchase Firm Shares or Additional Shares hereunder, and if
     the Firm Shares or Additional Shares with respect to which such default
     relates do not (after giving effect to arrangements, if any, made by you
     pursuant to subsection (b) below) exceed in the aggregate 10% of the number
     of Firm Shares or Additional Shares, to which the default relates shall be
     purchased by the non-defaulting Underwriters in proportion to the
     respective proportions which the numbers of Firm Shares set forth opposite
     their respective names in Schedule I hereto bear to the aggregate number of
     Firm Shares set forth opposite the names of the non-defaulting
     Underwriters.

          (b) In the event that such default relates to more than 10% of the
     Firm Shares or Additional Shares, as the case may be, the Representatives
     may in their discretion arrange for yourself or for another party or
     parties (including any non-defaulting Underwriter or

                                       21
<PAGE>

     Underwriters who so agree) to purchase such Firm Shares or Additional
     Shares, as the case may be, to which such default relates on the terms
     contained herein. In the event that within five calendar days after such a
     default you do not arrange for the purchase of the Firm Shares or
     Additional Shares, as the case may be, to which such default relates as
     provided in this Section 9, this Agreement or, in the case of a default
     with respect to the Additional Shares, the obligations of the Underwriters
     to purchase and of the Company to sell the Additional Shares shall
     thereupon terminate, without liability on the part of the Company with
     respect thereto (except in each case as provided in Section 5, 7(a) and 8
     hereof) or the Underwriters, but nothing in this Agreement shall relieve a
     defaulting Underwriter or Underwriters of its or their liability, if any,
     to the other Underwriters and the Company for damages occasioned by its or
     their default hereunder.

          (c) In the event that the Firm Shares or Additional Shares to which
     the default relates are to be purchased by the non-defaulting Underwriters,
     or are to be purchased by another party or parties as aforesaid, the
     Representatives or the Company shall have the right to postpone the Closing
     Date or the applicable Additional Closing Date, as the case may be, for a
     period, not exceeding five business days, in order to effect whatever
     changes may thereby be made necessary in the Registration Statement or the
     Prospectus or in any other documents and arrangements, and the Company
     agrees to file promptly any amendment or supplement to the Registration
     Statement or the Prospectus which, in the opinion of Underwriters' Counsel,
     may thereby be made necessary or advisable. The term "Underwriter" as used
     in this Agreement shall include any party substituted under this Section 9
     with like effect as if it had originally been a party to this Agreement
     with respect to such Firm Shares and Additional Shares.

     10.  Survival of Representations and Agreements.  All representations and
          ------------------------------------------
warranties, covenants and agreements of the Underwriters and the Company
contained in this Agreement, including the agreements contained in Section 5,
the indemnity agreements contained in Section 7 and the contribution agreements
contained in Section 8, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter or any
controlling person thereof or by or on behalf of the Company, any of its
officers and directors or any controlling person thereof, and shall survive
delivery of and payment for the Shares to and by the Underwriters.  The
representations contained in Section 1 and the agreements contained in Sections
5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement,
including termination pursuant to Section 9 or 11 hereof.

     11.  Effective Date of Agreement; Termination.
          ----------------------------------------

          (a) This Agreement shall become effective, upon the later of when (i)
     the Representatives and the Company shall have received notification of the
     effectiveness of the Registration Statement or (ii) the execution of this
     Agreement. If either the initial public offering price or the purchase
     price per Share has not been agreed upon prior to 5:00 P.M., New York time,
     on the fifth full business day after the Registration Statement shall have
     become effective, this Agreement shall thereupon terminate without
     liability to the Company or the Underwriters except as herein expressly
     provided. Until this Agreement becomes effective as aforesaid, it may be
     terminated by the Company by

                                       22
<PAGE>

     notifying you or by the Representatives notifying the Company.
     Notwithstanding the foregoing, the provisions of this Section 11 and of
     Section 1, 5, 7 and 8 hereof shall at all times be in full force and
     effect.

          (b) You shall have the right to terminate this Agreement at any time
     prior to the Closing Date or the obligations of the Underwriters to
     purchase Additional Shares at any time prior to the applicable Additional
     Closing Date, as the case may be (A) if any domestic or international event
     or act or occurrence has materially disrupted, or in the opinion of the
     Representatives will in the immediate future materially disrupt, the market
     for the Company's securities or securities in general; or (B) if trading on
     the New York or American Stock Exchanges or the Nasdaq shall have been
     suspended, or minimum or maximum prices for trading shall have been fixed,
     or maximum ranges for prices for securities shall have been required, on
     the New York or American Stock Exchanges or the Nasdaq by the New York or
     American Stock Exchanges, the National Association of Securities Dealers,
     Inc. or by order of the Commission or any other governmental authority
     having jurisdiction; or (C) if a banking moratorium has been declared by a
     state or federal authority or if any new restriction materially adversely
     affecting the distribution of the Firm Shares or the Additional Shares, as
     the case may be, shall have become effective; or (D) (i) if the United
     States becomes engaged in hostilities or there is an escalation of
     hostilities involving the United States or there is a declaration of a
     national emergency or war by the United States or (ii) if there shall have
     been such change in political, financial or economic conditions if the
     effect of any such event in (i) or (ii) as in the judgment of the
     Representatives makes it impracticable or inadvisable to proceed with the
     offering, sale and delivery of the Firm Shares or the Additional Shares, as
     the case may be, on the terms contemplated by the Prospectus.

          (c) Any notice of termination pursuant to this Section 11 shall be by
     telephone, telex, or telegraph, confirmed in writing by letter.

          (d) If this Agreement shall be terminated pursuant to any of the
     provisions hereof (otherwise than pursuant to (i) notification by the
     Representatives as provided in Section 11(a) hereof or (ii) Section 9(b) or
     11(b) hereof), or if the sale of the Shares provided for herein is not
     consummated because any condition to the obligations of the Underwriters
     set forth herein is not satisfied or because of any refusal, inability or
     failure on the part of the Company to perform any agreement herein or
     comply with any provision hereof, the Company will, subject to demand by
     the Representatives, reimburse the Underwriters for all out-of-pocket
     expenses (including the fees and expenses of their counsel), incurred by
     the Underwriters in connection herewith.

     12.  Notices.  All communications hereunder, except as may be otherwise
          -------
specifically provided herein, shall be in writing and , if sent to any
Underwriter, shall be mailed, delivered, or telexed or telegraphed and confirmed

          -------
shall be binding upon, the Underwriters and the Company and the controlling

as such, of Shares from any of the Underwriters.

                                AVERSTAR, INC.

                    _______________________________________


          AverStar, Inc., a corporation organized and existing under the laws of
the State of Delaware, hereby certifies as follows:

          1.   The name of the corporation is AverStar Inc. (the "Corporation").

<PAGE>

          SECTION 1.  Authorized Capital. The total number of shares of stock
                      ------------------
which the Corporation shall have authority to issue is Twenty-Six Million
(26,000,000) shares, of which Twenty-Five Million (25,000,000) shares shall be

shall be preferred stock, par value $.001 per share.

          SECTION 2.  Preferred Stock. The designations and the powers,
                      ---------------
preferences and rights, and the qualifications, limitations or restrictions
thereof, of each class of stock are as follows:

          The Board of Directors is expressly authorized at any time, and from
time to time, to provide for the issuance of shares of preferred stock in one or
more series, with such voting powers, full or limited, or without voting powers
and with such designations, preferences and relative, participating, optional or
other special rights, and qualifications, limitations or restrictions thereof,
as shall be stated and expressed in the resolution or resolutions providing for
the issue thereof adopted by the Board of Directors, subject to the limitations
prescribed by law and in accordance with the provisions hereof, including (but
without limiting the generality thereof) the following:

          (a)  The designation of the series and the number of shares to
constitute the series;

          (b)  The dividend rate, if any, of the series, the conditions and
dates upon which such dividends shall be payable, the relation which such
dividends shall bear to the dividends payable on any other class or classes of
stock, and whether such dividends shall be cumulative or noncumulative;

          (c)  Whether the shares of the series shall be subject to redemption
by the Corporation and, if made subject to such redemption, the times, prices
and other terms and conditions of such redemption;

          (d)  The terms and amount of any sinking fund provided for the
purchase or redemption of the shares of the series;

          (e)  Whether or not the shares of the series shall be convertible into
or exchangeable for shares of any other class or classes or of any other series
of any class or classes of stock of the Corporation, and, if provision be made
for conversion or exchange, the times, prices, rates, adjustments and other
terms and conditions of such conversion or exchange;

          (f)  The extent, if any, to which the holders of the shares of the
series shall be entitled to vote with respect to the election of directors or
otherwise;

          (g)  The restrictions, if any, on the issue or reissue of any
additional preferred stock; and

          (h)  The rights of the holders of the shares of the series upon the
dissolution, liquidation, or winding up of the Corporation.

                                      -2-
<PAGE>

          Subject to the prior or equal rights, if any, of the preferred stock
of any and all series stated and expressed by the Board of Directors in the
resolution or resolutions providing for the issuance of such preferred stock,
the holders of common stock shall be entitled (i) to receive dividends when and
as declared by the Board of Directors out of any funds legally available
therefor, (ii) in the event of any dissolution, liquidation or winding up of the
Corporation, to receive the remaining assets of the Corporation, ratably
according to the number of shares of common stock held, and (iii) to one vote
for each share of common stock held on all matters submitted to a vote of
stockholders.  No holder of common stock shall have any preemptive right to
purchase or subscribe for any part of any issue of stock or of securities of the
Corporation convertible into stock of any class whatsoever, whether now or
hereafter authorized.

          FIFTH:  Board of Directors.

          SECTION 1.  Number.  The business and affairs of the Corporation shall
                      ------
be managed by or under the direction of the Board of Directors.  The number of
directors, subject to any right of the holders of any series of Preferred Stock
to elect additional directors, shall be fixed from time to time by the Board of
Directors pursuant to the By-Laws.

          SECTION 2.  Classification.  The Board of Directors shall be divided
                      --------------
into three classes, as nearly equal in number as the then total number of
directors constituting the whole board permits, with the term of office of one
class expiring each year.  At each annual meeting of stockholders the successors
to the class of directors whose term shall then expire shall be elected to hold
office for a term expiring at the third succeeding annual meeting and each
director so elected shall hold office until his successor is elected and
qualified, or until his earlier resignation or removal.

          If the number of directors is changed, any increase or decrease in the
number of directors shall be apportioned among the three classes so as to make
all classes as nearly equal in number as possible, and the Board of Directors
shall decide which class shall contain an unequal number of directors.
Notwithstanding the foregoing, whenever holders of any shares of Preferred
Stock, or any series thereof, shall be entitled, voting separately as a class,
to elect any directors, all directors so elected shall be allocated, each time
they are so elected, to the class whose term expires at the next succeeding
annual meeting of stockholders.

          SECTION 3.  Nomination.  Only persons who are nominated in accordance
                      ----------
with the procedures set forth in this Article Fifth, Section 3 of the
Certificate of Incorporation shall be eligible to serve as directors.
Nominations of persons for election to the Board of Directors of the Corporation
may be made at an annual meeting of stockholders (a) by or at the direction of
the Board of Directors or (b) by any stockholder of the Corporation who is a
stockholder of record at the time of giving notice provided for in this Section
3, who shall be entitled to vote for the election of directors at the meeting
and who complies with the procedures set forth below.  Any such nominations
(other than those made by or at the direction of the Board of Directors) must be

the Corporation unless nominated in accordance with the procedures set forth in
this Section 3. If the Board of Directors shall determine, based on the facts,

nomination shall be disregarded. Notwithstanding the foregoing provisions of
this Section 3, a stockholder shall also comply with all applicable requirements

shall obtain the advice of a financial advisor to the effect that such Business
Combination is fair to the holders of Voting Shares (other than an Interested
Stockholder); provided, further, that the Continuing Directors shall have no
obligation to approve such Business Combination (but meeting such criteria shall

               of Voting Shares beneficially owned by an Interested Stockholder
               (1) within the two-year period immediately prior to the
               Announcement Date, (2) within the two-year period immediately

class or series of outstanding Voting Shares (including Common Stock) shall be

such class or series of Voting Shares which are beneficially owned by an
Interested Stockholder and, if an Interested Stockholder beneficially owns
shares of any class or series of Voting Shares which were acquired with varying
forms of consideration, the form of consideration for such class or series of
Voting Shares shall be either cash or the form used to acquire the largest
number of shares of such class or series of Voting Shares beneficially owned by
it. The price determined in accordance with subsections (a) and (b) of this
Section 2 shall be subject to appropriate adjustment in the event of any
recapitalization, stock dividend, stock split, combination of shares or similar
event;

               the regular date therefor any full quarterly dividends (whether
               or not cumulative) on any outstanding stock having preference
               over the Common Stock as to dividends or liquidation;

                    (ii)  there shall have been (1) no reduction in the annual
               rate of dividends paid on the Common Stock (except as necessary
               to reflect any subdivision of the Common Stock), except as
               approved by a majority of the Continuing Directors, and (2) an
               increase in such annual rate of dividends as necessary to reflect
               any reclassification (including any reverse stock split),
               recapitalization, reorganization or any similar transaction which
               has the effect of reducing the number of outstanding shares of
               the Common Stock, unless the failure to so increase such annual
               rate is approved by a majority of the Continuing Directors; and

                    (iii) such Interested Stockholder shall not have become the
               Beneficial Owner (as hereinafter defined) of any additional
               Voting Shares except as part of the transaction in which it

proposed Business Combination or (ii) if no vote on such Business Combination is
required, 60 days prior to the consummation of such Business Combination

Continuing Directors, or any of them, may have furnished in writing and, if
deemed advisable by a majority of the Continuing Directors, an opinion of a
reputable investment banking firm as to the fairness (or lack of fairness) of
the terms of such Business Combination, from the point of view of the holders of
Voting Shares other than an Interested Stockholder (such investment banking firm
to be selected by a majority of the Continuing Directors, to be furnished with
all information it reasonably requests and to be paid a reasonable fee for its

Seventh:

               (a)  "Business Combination" shall mean any transaction which is
referred to in any one or more of subsections (a) through (e) of Section 1 of
this Article Seventh.

               (b)  "Voting Shares" shall mean shares of all classes and series

               (c)  "Person" shall mean any individual, corporation,

               (d)  "Interested Stockholder" shall mean any person (other than

the Corporation or any Subsidiary of the Corporation or any entity holding

               within the two-year period immediately prior to the date in
               question beneficially owned by an Interested Stockholder.

Notwithstanding the foregoing, no person shall become an Interested Stockholder
as the result of an acquisition of Voting Shares by the Corporation which, by
reducing the number of shares of Common Stock outstanding, increases the
proportionate number of shares beneficially owned by such person to 15% or more
of the Voting Shares of the Corporation then outstanding; provided, however,
                                                          --------  -------

Shares of the Corporation then outstanding by reason of shares purchased by the
Corporation, and after such purchases by the Corporation becomes the Beneficial
Owner of any additional Voting Shares of the Corporation, then such person shall
be deemed to be an Interested Stockholder.

For purposes of determining whether a person is an "Interested Stockholder," the
number of Voting Shares deemed to be outstanding shall include shares deemed
owned through application of subsection (e) below but shall not include any
other Voting Shares which may be issuable pursuant to any agreement, arrangement
or understanding, or upon exercise of conversion rights, warrants or options, or

               (whether such right is exercisable immediately or within 60 days)
               pursuant to (A) any agreement, arrangement or understanding; (B)
               upon the exercise of any option, warrants or rights; or (C) upon
               the conversion of a security; or (2) the right to vote or to
               direct the voting thereof pursuant to any agreement, arrangement
               or understanding; or

                    (iii) which is beneficially owned, directly or indirectly,
               by any other person with which such person or any of its
               Affiliates or Associates has any agreement, arrangement or
               understanding for the purpose of acquiring, holding, voting or
               disposing of any Voting Shares.

               (f)  "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Exchange Act.

          (g)  "Subsidiary" shall mean any corporation, partnership or other
entity of which a majority of any class of equity security (as defined in Rule
3a(11)-1 of the General Rules and Regulations under the Exchange Act), is owned,
directly or indirectly, by the Corporation; provided, however, that for purposes
of the definition of Interested Stockholder set forth above in subsection (d),
the term "Subsidiary" shall mean only a corporation, partnership or other entity
of which a majority of each class of equity security is beneficially owned,
directly or indirectly, by the Corporation.

          (h)  "Continuing Director" shall mean any member of the Board of
Directors who is unaffiliated with, and not a nominee of, an "Interested
Stockholder," and was a director prior to any person becoming or was approved or
not opposed by a majority of the Board of Directors in office prior to any
person becoming an Interested Stockholder.

          (i)  "Announcement Date" shall mean the date of the first public
announcement of the proposed Business Combination.

Stockholder.

the shares are listed or admitted for trading on any national securities
exchange or included in The Nasdaq National Market or Nasdaq SmallCap Market,
the last reported sales price as reported on such exchange or market; (B) if the
shares are not listed or admitted for trading on any national securities
exchange or included in The Nasdaq National Market or Nasdaq SmallCap Market,
the average of the last reported closing bid and asked quotation for the shares
as reported on the National Association of Securities Dealers Automated

national securities exchange or included in The Nasdaq National Market or Nasdaq
SmallCap Market or quoted by NASDAQ or a similar service, the average of the
last reported bid and asked quotation for the shares as quoted by a market maker
in the shares (or if there is more than one market maker, the bid and asked
quotation shall be obtained from two market makers and the average of the lowest
bid and highest asked quotation), or (D) if no such quotations are available,
the fair market value on the date in question of a share of such stock as
determined by a majority of the Continuing Directors in good faith; and (ii) in
the case of property other than cash or stock, the fair market value of such
property on the date in question as determined by a majority of the Continuing
Directors in good faith.

     SECTION 4.  Determinations by the Board of Directors. A majority of the
                 ----------------------------------------
Continuing Directors shall have the power and duty to determine for the purposes
of this Article Seventh, on the basis of information known to them after
reasonable inquiry, all facts necessary to determine compliance with this
Article Seventh including, without limitation, (i) whether a person is an
Interested Stockholder, (ii) the number of Voting Shares beneficially owned by

for the issuance or transfer of securities by the Corporation or any Subsidiary
in any Business Combination has, an aggregate Fair Market Value of $8,000,000 or
more, (v) whether the requirements of Section 2 of this Article Seventh have
been met and (vi) such other matters with respect to which a determination is
required under this Article Seventh. The good faith determination of a majority
of the Continuing Directors on such matters shall be conclusive and binding for
all purposes of this Article Seventh, and no director will have any liability to
the Corporation or any other person by reason of any such determination so made.

     SECTION 5. Fiduciary Obligations. Nothing contained in this Article Seventh
                 ---------------------
shall be construed to relieve the members of the Board of Directors or an
Interested Stockholder from any fiduciary obligation imposed by law.

     The fact that any Business Combination complies with the provisions of
Section 2 of this Article Seventh shall not be construed to impose any fiduciary
duty, obligation or responsibility on the Board of Directors, or any member
thereof, to approve such Business Combination or recommend its adoption or
approval to the stockholders of the Corporation, nor shall such compliance
limit, prohibit or otherwise restrict in any manner the Board of Directors, or
any member thereof, with respect to evaluations of or actions and responses
taken with respect to such Business Combination.

     EIGHTH: Liability of Directors. No director shall be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; provided, however, that to the extent required by the
provisions of Section 102(b)(7) of the General Corporation Law of the State of
Delaware or any successor statute, or any other laws of the State of Delaware,
this provision shall not eliminate or limit the liability of a director (i) for
any breach of the director's duty of loyalty to the Corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the General Corporation Law of the State of Delaware, or (iv) for any
transaction from which the director derived an improper personal benefit. If the
General Corporation Law of the State of Delaware hereafter is amended to
authorize the further elimination or limitation on personal liability of
directors, then the liability of a director of the Corporation, in addition to
the limitation on personal liability provided herein, shall be limited to the
fullest extent permitted by the amended General Corporation Law of the State of
Delaware. Any repeal or modification of this Article Eighth by the stockholders
of the Corporation shall be prospective only, and shall not adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such repeal or modification.

     NINTH:  Indemnification and Advancement of Expenses

     SECTION 1.  Indemnification. The Corporation shall indemnify each person
                 ---------------
who was or is made a party or is threatened to be made a party to or is involved
in any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or

                                      -12-
<PAGE>

investigative (other than an action by or in the right of the Corporation)
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer
of the Corporation or is or was serving at the request of the Corporation as
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged action in an
official capacity as a director, officer, employee or agent or alleged action in
any other capacity while service as a director, officer, employee or agent, to
the maximum extent authorized by the General Corporation Law of the State of
Delaware, as the same exists or may hereafter be amended (but, in the case of
any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties, amounts paid or to be paid in settlement) actually and
reasonably incurred by such person in connection with such proceeding if the
person acted in good faith and in a manner the person reasonably believed to be
in or not opposed to the best interests of the Corporation, and, with respect to
any criminal proceeding, had no reasonable cause to believe that the person's
conduct was unlawful. Such indemnification shall continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of his or her heirs, executors and administrators. The right to
indemnification conferred in this Article Ninth shall be a contract right and
shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided
that, if the General Corporation Law of the State of Delaware so requires, the
payment of such expenses incurred by a director or officer in advance of the
final disposition of a proceeding shall be made only upon receipt by the
Corporation of an undertaking by or on behalf of such person to repay all
amounts so advanced if it shall ultimately be determined that such person is not
entitled to be indemnified by the Corporation as authorized in this Article
Ninth or otherwise.

     SECTION 2.  Nonexclusivity. The right to indemnification and advancement of
                 --------------
expenses conferred on any person by this Article Ninth shall not limit the
Corporation from providing any other indemnification permitted by law nor shall
it be deemed exclusive of any other right which any such person may have or
hereafter acquire under any statute, provision of this Certificate of
Incorporation, by-law, agreement, vote of stockholders or disinterested
directors or otherwise.

     SECTION 3.  Insurance. The Corporation may purchase and maintain insurance,
                 ---------
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another corporation, partnership, joint venture, trust or
other enterprises against any expenses, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the General Corporation Law of the State of Delaware.

     TENTH:  Amendment of By-Laws. The Board of Directors shall have power to
make, amend and repeal the By-Laws. Any By-Laws made by the Board of Directors
under the powers conferred hereby may be amended or repealed by the Board of
Directors or by the

                                      -13-

stockholders. Notwithstanding the foregoing and anything contained in this
Certificate of Incorporation to the contrary, Article II, Sections 2.3, 2.4, 2.6
and 2.11, Article II, Sections 3.1 and 3.2 and Article VIII, Section 8.1 of the
By-Laws shall not be amended or repealed, and no provision inconsistent
therewith shall be adopted, without the affirmative vote of the holders of
record of outstanding shares representing (i) at least 80% of the voting power
of the then outstanding Voting Shares (as defined in Article Seventh) of the
Corporation, voting together as a single class and (ii) if there is then an
Interested Stockholder (as defined in Article Seventh), at least a majority of
the voting power of the then outstanding Voting Shares of the Corporation,
voting together as a single class, which are not beneficially owned, directly or
indirectly, by an Interested Stockholder, effected at a duly called annual or
special meeting of such stockholders, with such prior notice as is required by
the By-Laws; provided, however, that the provisions of this sentence shall not
apply to any amendment, repeal or adoption of any inconsistent provision
declared advisable by the Board of Directors by the affirmative vote of a
majority of the total number of directors which the Corporation would have if
there were no vacancies on the Board of Directors and, if there is then an
Interested Stockholder, a majority of the Continuing Directors (as defined above
in Article Seventh).

     ELEVENTH:  Amendment of Certificate of Incorporation. The Corporation
reserves the right to amend or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute, and all rights conferred upon stockholders herein are granted subject
to this reservation. Notwithstanding any other provision of this Certificate of
Incorporation or the By-Laws (and in addition to any other vote that may be
required by applicable law, by this Certificate of Incorporation or by the By-
Laws), the affirmative vote of the holders of record of outstanding shares
representing (i) at least 80% of the voting power of the then outstanding Voting
Shares of the Corporation, voting together as a single class, and (ii) if there
is then an Interested Stockholder (as defined in Article Seventh), at least a
majority of the voting power of the then outstanding Voting Shares of the
Corporation, voting together as a single class, which are not beneficially
owned, directly or indirectly, by an Interested Stockholder, effected at a duly
called annual or special meeting of such stockholders, with prior notice, and
with a vote and not by written consent, shall be required to amend or repeal, or
adopt any provisions inconsistent with this Article Eleventh, or Articles Fifth
through Tenth of this Certificate of Incorporation; provided, however, that the
provisions of this sentence shall not apply to any amendment, repeal or adoption
of any inconsistent provision declared advisable by the Board of Directors by
the affirmative vote of a majority of the total number of directors which the
Corporation would have if there were no vacancies on the Board of Directors and,
if there is then an Interested Stockholder, a majority of the Continuing
Directors (as defined above in Article Seventh).

Burlington, MA 01803

Ladies and Gentlemen:

     On the date hereof, AverStar, Inc., a Delaware corporation (the "Company"),
is transmitting for filing with the Securities and Exchange Commission
Amendment No. 1 to a Registration Statement under the Securities Act of 1933, as
amended, on Form S-1 (the "Registration Statement") relating to the sale of up
to 4,600,000 shares (the "Shares") of the Company's common stock, par value
$.001 per share (the "Common Stock"), (including 4,000,000 shares to be sold
by the Company, and 600,000 shares subject to the underwriters' over-allotment
option. This opinion is an exhibit to the Registration Statement.

     We have acted as special counsel to the Company with respect to certain
corporate and securities matters, and in such capacity we have participated in
various corporate and other proceedings taken by or on behalf of the Company in
connection with the proposed offer and sale of the Shares by the Company as
contemplated by the Registration Statement.  However, we are not general counsel
to the Company and would not ordinarily be familiar with or aware of matters
relating to the Company unless they are brought to our attention by
representatives of the Company.

     We have examined copies (in each case signed, certified or otherwise proven
to our satisfaction to be genuine) of the Company's Certificate of Incorporation
and all amendments thereto, and By-Laws as presently in effect, minutes and
other instruments evidencing actions taken by the Company's directors and
stockholders, the Registration Statement and exhibits thereto, and such other
documents and instruments relating to the Company and the proposed offering as
we have deemed necessary under the circumstances. In our examination of all such
agreements, documents, certificates and instruments, we have assumed the
completeness of the minutes submitted to us by the Company, the genuineness of
all signatures, the legal capacity of all signatures and the authenticity of all
agreements, documents, certificates and instruments submitted to us as originals
and the

conformity with the originals of all agreements, instruments, documents and
certificates submitted to us as copies.

     Except as expressly set forth in the next sentence, we express no opinion
on the laws of any jurisdiction other than the State of New York, the federal
laws of the United States and, to the extent set forth below, the laws of the
State of Delaware. This opinion, insofar as it relates to the law of Delaware,
based solely on our reading of standard published compilations of the Delaware
General Corporation Law. We express no opinion as to the application of the
securities or "blue sky" laws of any state, including the State of Delaware or
the State of New York, to the offer and sale of the Shares.

     Our opinion in paragraph 1 below as to the due incorporation of the Company
in its state of incorporation is (i) based solely upon a Certificate of Good
Standing from the Secretary of State of the State of Delaware and (ii) rendered
as of the date of said certificate.

     Based on the foregoing, and subject to and in reliance on the accuracy and
completeness of the information relevant thereto provided to us, it is our
opinion that:

     1.   The Company has been duly incorporated under the laws of the State of
Delaware and, upon proper filing of the Second Amended and Restated Certificate
of Incorporation of the Company in the form filed as Exhibit 3.3  to the
Registration Statement, the Company will have an authorized capital stock
consisting of 25,000,000 shares of Common Stock and 1,000,000 shares of
preferred stock, par value $.001 per share.

     2. Upon proper filing of the Second Amended and Restated Certificate of
Incorporation of the Company in the form filed as Exhibit 3.3 to the
Registration Statement, the maximum of 4,600,000 shares of Common Stock to be
sold by the Company will have been duly authorized and, subject to the
effectiveness of the Registration Statement and compliance with applicable
securities or other laws of the states of the United States in which the Shares
will be offered and/or sold in the proposed public offering, when issued and
delivered against payment therefor in accordance with the terms set forth in the
Registration Statement, will be legally and validly issued, fully paid and non-
assessable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and as an exhibit to any filing made by the Company under
the securities or other laws of any state

of the United States, which relate to the proposed public offering which is the
subject of this opinion, and to the reference to this firm appearing under the
heading "Legal Matters" in the prospectus which is contained in the Registration
Statement.

     This opinion is as of the date hereof and we undertake no obligation to
advise you of any change, any applicable law or in facts or circumstances which
might affect any matters or opinions set forth herein.  This opinion is
furnished to you in connection with the filing of the Registration Statement,
and is not to be used, circulated, quoted or otherwise relied upon for any other
purposes, except as expressly provided in the preceding paragraph.

                                    Very truly yours,

          Debt to EBITDA Ratio shall be less than or equal to 3.0 to 1.0,
          calculated as of the applicable date of determination for Excess Cash
          Flow.

     Mandatory payments arising from any Excess Cash Event, Subordinate Debt
Issuance and/or Equity Issuance shall be due and payable in full upon the
occurrence of such Excess Cash Event, Subordinate Debt Issuance and/or Equity
Issuance (as applicable), and mandatory payments arising from Excess Cash Flow
shall be due and payable in full simultaneously with the Agent's receipt of the
Borrowing Base/Non-Default Certificate for the month of December of each
calendar year (or the date on which such certificate is required to be
delivered, if the Borrowers fail to deliver the same as required by this
Agreement), which Borrowing Base/Non-Default Certificate shall include the
Borrower's detailed computation of Excess Cash Flow. Furthermore, if the
Mandatory Payment amount for Excess Cash Flow set forth in the Year End
Compliance Certificate (the "Required Excess Cash Flow Payment") shall be
greater than the Mandatory Payment arising from Excess Cash Flow paid by the
Borrowers pursuant to the immediately preceding sentence (the "Excess Cash Flow
Paid Amount"), then the Borrowers shall make an additional Mandatory Payment,
simultaneously with the Borrower's submission of the Year End Compliance
Certificate (or the date on which such certificate is required to be delivered,
if the Borrowers fail to deliver the same as required by this Agreement), in an
amount equal to the difference between the Required Excess Cash Flow Payment and
the Excess Cash Flow Paid Amount

Any mandatory payment(s) made pursuant to this Section 1.5 shall be accompanied
by the applicable Prepayment Fee, if any, payable pursuant to Exhibit 3 of this
                                                              ---------
Agreement. Such mandatory payments shall be applied to the Term Facilities, in
inverse order of maturities, on a pro-rata basis (unless all of the Note "B"
Holders shall have instructed the Agent in writing to apply such payments first
to Term Facility "A" until Term Facility "A" shall have

                                      19

operations, as the Agent deems necessary or appropriate, in its sole discretion.
All field audits shall be at the cost and expense of the Borrowers; provided,
however, that, except as otherwise expressly set forth below, in the absence of
an Event of Default hereunder, the cost and expense to the Borrowers of field
audits shall be limited to the cost and expense of no more than two (2) field
audits conducted during any twelve (12) month period (the "Field Audit Cost

respect to the joinder of a new Borrower pursuant to Section 1.10 of this
Agreement shall not be subject to the Field Audit Cost Limitation.

during the applicable quarter. Notwithstanding the foregoing, during the six (6)
month period immediately following the Closing Date, the Commitment Fee annual
percentage shall be fixed and equal to one-half of one percent (.50%). The
Commitment Fee shall be calculated on the basis of the actual number of days
elapsed and a three hundred sixty (360) day year, shall be due for any quarter
in which the Revolving Facility is available to the Borrower or outstanding (for
all or any portion of such quarter), and shall be payable in arrears, commencing

reasonable requirements for letters of credit normally and customarily imposed

letters of credit, provided that no Event of Default has occurred and is
continuing, and no act, event or condition which with notice or the passage of
time, or both, would constitute an Event of Default has occurred and is

Revolving Facility Lender shall purchase from First Union a risk participation
with respect to such Letter(s) of Credit in an amount equal to such Lender's
Percentage of such Letter(s) of Credit. First Union shall have no obligation to
issue any Letter of Credit which has an expiration date beyond the Revolving
Facility Maturity Date, unless the Borrowers shall have deposited with the
Agent, concurrent with the issuance of any such Letter of Credit, cash security
therefor in an amount equal to the face amount of the Letter of Credit. Any

event or condition has occurred which with notice or the passage of time, or
both, would constitute an Event of Default under the terms and provisions of the

Facility Lender shall purchase from First Union such risk participations in the
Letter(s) of Credit as shall be necessary to cause each such Lender to share the
funding obligations with respect thereto ratably in accordance with its
particular Percentage. It is expressly understood and agreed that all

Loan have been paid and satisfied in full, (ii) all Letters of Credit have been
canceled or expired, and (iii) no Lender has any further obligation or

                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

     To induce the Lender(s) to enter into this Agreement, each Borrower jointly
and severally represents, warrants, covenants and agrees as follows:

     Section 5.1  Corporate Existence and Qualification.  Each Borrower is a
                  -------------------------------------
corporation duly organized, validly existing and in good standing under the laws
of its state of incorporation, with all corporate power and authority and all
necessary licenses and permits to own, operate and lease its properties and
carry on its business as now being conducted.  Each Borrower is duly qualified
and authorized to do business and is in good standing in each jurisdiction in
which the nature of its activities or the character of its properties makes
qualification necessary, except for such failures to qualify which would not
have a material adverse effect on (a) the Borrowers, taken as a whole, or any of
the Principal Borrowers or (b) the ability of the Borrowers, taken as a whole,
or any of the Principal Borrowers, to conduct their respective business or
operations.

     Section 5.2  Corporate Authority; Noncontravention.  The execution,
                  -------------------------------------
delivery and performance by each Borrower of its obligations set forth in this
Agreement, the Notes and the other Loan Documents (i) have been duly authorized
by all necessary corporate and/or stockholder action; (ii) do not require the
consent of any governmental body, agency or authority; (iii) will not violate or
result in (and with notice or the lapse of time will not violate or result in)
the breach of any provision of the Articles of Incorporation/Certificate of
Incorporation or By-laws of such Borrower, any material indenture, material
instrument, material agreement or other material undertaking to which such
Borrower is a party or by which such Borrower is bound, or any order or
regulation of any governmental authority or arbitration board or tribunal; and
(iv) except as expressly permitted by the terms and provisions of this
Agreement, result in the creation of a lien, charge or encumbrance of any nature
upon any of the properties or assets of any Borrower. When the Loan Documents
are executed and delivered, they will constitute legal, valid and binding
obligations of the Borrowers, enforceable against the Borrowers in accordance
with their respective terms, except as such enforceability may be subject to the
effect of any applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors' rights generally and subject to the effect of
general principals of equity (whether considered in a proceeding in equity or at
law).

     Section 5.3  Financial Position.  The financial statements dated December
                  ------------------
31, 1998, copies of which have been delivered to the Agent, present fairly the
financial condition of the Borrowers as of the date thereof and the results of
the Borrowers' operations for the periods indicated therein, were prepared in
accordance with GAAP, are true and accurate in all material respects, and with
respect to the Borrowers (other than CBSI), are not misleading in any respect.
All liabilities, fixed or contingent (other than those liabilities, whether
fixed or contingent, not required by GAAP to be reflected or

                                      29
<PAGE>

reserved on financial statements and which (i) are not letters of credit or (ii)
do not exceed $10,000.00 individually or $200,000 in the aggregate), are fully
shown or provided for on the referenced financial statements or the notes
thereto as of the dates thereof. There has been no material adverse change in
the business, property or condition (financial or otherwise) of any Borrower
since the date of the most recent financial statement dated December 31, 1998,
and all other financial statements and information delivered to First Union
prior to the Closing Date are true and accurate in all material respects, and
are not misleading in any material respect.

     Section 5.4  Payment of Taxes.  Each Borrower has filed all tax returns and
                  ----------------
reports required to be filed by it with the United States Government and/or with
all state and local governments, and has paid in full or made adequate provision
on its books for the payment of all taxes, interest, penalties, assessments or
deficiencies shown to be due or claimed to be due on or in respect of such tax
returns and reports, except to the extent that the validity or amount thereof is
being contested in good faith by appropriate proceedings and the non-payment
thereof pending such contest will not result in the execution of any tax lien or
otherwise adversely affect the Agent's interests in any part of the Collateral.

     Section 5.5  Accuracy of Submitted Information; Omissions.  All documents,
                  --------------------------------------------
certificates, information, materials and financial statements (other than
projections) furnished or to be furnished to the Agent or any Lender pursuant to
this Agreement or otherwise in connection with the Loan, as of the date
furnished, (i) are and will be true and correct in all material respects; (ii)
do not and will not contain any untrue statement of a material fact; and (iii)
do not and will not omit any material fact necessary to make the statements
contained therein or herein not misleading.  No Borrower is aware of any fact
which has not been disclosed to the Agent in writing which materially adversely
affects, or so far as any Borrower can now reasonably foresee, could reasonably
be expected to materially adversely affect, the properties, business, profit or
condition (financial or otherwise) of the Borrowers, taken as a whole, or any of
the Principal Borrowers or the ability of the Borrowers, taken as a whole, or
any of the Principal Borrowers to perform their respective obligations under
this Agreement or any other Loan Document.

knowledge, there is no threatened) suspension, debarment or termination for
default issued or being pursued by the Government or any other adverse

Government Contracts which have a remaining value in excess of One Million and

5.7 hereto, no Borrower is (a) in default in the performance of any obligation,
- ---
covenant or condition contained in any agreement to which it is a party, which
default could reasonably be expected to materially adversely affect the
properties, business, profit or condition (financial or otherwise) of the
Borrowers, taken as a whole, or any of the Principal Borrowers or the ability of
the Borrowers, taken as a whole, or any of the Principal Borrowers to perform
their respective obligations under this Agreement or any other Loan Document; or
(b) aware of any condition, act, event or occurrence, including, without
limitation, any pending or threatened litigation, legal or administrative
proceeding or investigation, not disclosed to the Agent in writing which could
reasonably be expected to prejudice the Agent's or any Lender's rights under any
Loan Document in any respect.

     Section 5.8   No Violations of Law.  No Borrower is in violation of any
                   --------------------
Applicable Laws, except for such violations which could not reasonably be
expected to materially adversely affect the properties, business, profit or
condition (financial or otherwise) of the Borrowers, taken as a whole, or any of
the Principal Borrowers or the ability of the Borrowers, taken as a whole, or
any of the Principal Borrowers to perform their respective obligations under
this Agreement or any other Loan Document; no Borrower has failed to obtain any
material license, material permit, material franchise or other material
governmental authorization necessary to the ownership of its properties or to
the conduct of its business; and each Borrower has conducted its business and
operations in full compliance with all Applicable Laws, except for any non-
compliance which is not reasonably likely to limit the ability of the Borrowers,
taken as a whole, or any of the Principal Borrowers, to conduct their respective
business or operations in the manner in which the same are now being conducted.

     Section 5.9   Litigation and Proceedings.  Except as set forth on Schedule

- ---
presently pending, or to the knowledge of each Borrower, threatened, in any
court, before any governmental agency or department, or before any arbitration
board or tribunal, which could reasonably be expected to result in any judgment
or liability against any Borrower in excess of Two Hundred Fifty Thousand and
No/100 Dollars ($250,000.00) and which is not fully covered by insurance. No
Borrower is aware of any existing basis that is reasonably likely to result in
any such action, suit or proceeding. No Borrower is in default in any material
respect of any applicable order, writ, injunction or decree of any court,
governmental authority or arbitration board or tribunal.

<PAGE>

waivers from each lessor/landlord of any premises at which such Borrower's
tangible personal property (having an aggregate value in excess of $500,000.00)
is located. Each such landlord waiver subordinates or will subordinate any
statutory, contractual or other lien the lessor/landlord may have in any of the
Collateral to the lien, operation and effect of the lien being granted to the
Agent pursuant to this Agreement.

material adverse affect on its business administration or operations.

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

representations and warranties made herein shall survive the making of the Loan,
and shall be deemed remade and redated as of the date of each request for an
advance or readvance of any Loan proceeds, unless any Borrower is unable to
remake and/or redate any such representation or warranty (other than the
representation and warranty set forth in Section 5.9 hereof), discloses the same

Borrowers shall have in effect at all times interest rate protection agreements

respects. All other Interest Rate Contracts shall be unsecured in all respects.
The Borrowers shall determine to their own satisfaction whether any such
Interest Rate Contract is sufficient to meet the Borrowers' needs for interest
rate protection, and neither the Agent nor any Lender shall have any obligation
or liability with respect thereto, nor any obligation to propose, quote or enter
into any Interest Rate Contract, unless such Interest Rate Contract shall be on
terms and conditions satisfactory to the applicable Lender in all respects.

ownership of the funds therein or whether such Obligations are owed jointly with
another or severally; the order and method of such application to be in the sole
discretion of the Agent.  The Agent's right to deduct sums due under the Loan
Documents from the account(s) of the Borrowers shall not relieve any Borrower
from its obligation to make all payments required by the Loan Documents as and
when required by the Loan Documents, and the Agent shall not have any obligation
to make any such deductions or any liability whatsoever for any failure to do
so.

Obligations to be immediately due and payable without demand, protest, notice of
protest, notice of default, presentment for payment or further notice of any
kind; provided, however, that payments of amounts hereunder shall not be
accelerated by reason of (i) a default in the payment of any sum due and payable
hereunder or pursuant to any other Loan Document (a "Payment Default"), unless
such Payment Default remains uncured for five (5) Business Days (with no notice
of default being required); and (ii) a default other than a Payment Default (a

Notwithstanding the foregoing, no notice of a Non-Payment Default shall be
required prior to acceleration or prior to the Agent or any Lender exercising
any other right or remedy under this Agreement or any other Loan Document, if

any kind or nature whatsoever on deposit with, held by or in the possession of
the Agent or any Lender in any capacity whatsoever, including, without
limitation, any deposits with the Agent or any Lender or any of its affiliates,
to the credit of or for the account of any Borrower. Notwithstanding any
applicable state law to the contrary (and without limiting the Agent's right,
for the convenience of the Borrowers, to charge any Borrower's account(s) for
any principal, interest or other sums payable pursuant to this Agreement, the
Notes or any other Loan Document when due), the Agent and/or any Lender is

beneficial ownership of the funds;

          (e)  Exercise all rights, powers and remedies of a secured party under
the Uniform Commercial Code in effect in the Commonwealth of Virginia, any other
jurisdiction in which the Collateral is located and/or any other applicable
law(s), including, without limitation, the right to (i) require the Borrowers to
assemble the Collateral (to the extent that it is movable) and make it available
to the Agent at a place to be designated by the Agent, and (ii) enter upon any
Borrower's premises, peaceably by the Agent's own means or with legal process,
and take possession of, render unusable or dispose of the

                                      53
<PAGE>

Collateral on such premises; each Borrower hereby agreeing not to resist or
interfere with any such action. The Agent agrees to give the Borrower written
notice of the time and place of any public sale of the Collateral or any part
thereof, and the time after which any private sale or any other intended
disposition of the Collateral is to be made, and such notice will be mailed,
postage prepaid, to the principal place of business of the Borrower, at least
ten (10) days before the time of any such sale or disposition, unless any
Applicable Law permits a shorter notice period. Each Borrower acknowledges and
agrees that the ten (10) day notice period (or shorter notice period permitted
by Applicable Law) is commercially reasonable. Each Borrower hereby authorizes
and appoints the Agent and its successors and assigns to (x) sell the
Collateral, and (y) declare that such Borrower assents to the passage of a
decree by a court of proper jurisdiction for the sale of the Collateral. Any
such sale pursuant to (x) or (y) above is to be made in accordance with the
applicable provisions of the laws and rules of procedure of the Commonwealth of
Virginia or other applicable law; and/or

          (f)  Proceed to enforce such other and additional rights and remedies
as the Agent and/or any Lender may have hereunder, and/or under any of the other
Loan Documents, or as may be provided by applicable law.

       It is expressly understood and agreed that the Agent and/or any Lender
may exercise its respective rights under this Agreement or under any other Loan
Document without exercising the rights or affecting the security afforded by any
other Loan Document, and it is further understood and agreed that the Agent may
proceed against all or any portion of the Collateral in such order and at such
times as the Agent, in its sole discretion, sees fit; and each Borrower hereby
expressly waives, to the extent permitted by law, all benefit of valuation,
appraisement, marshaling of assets and all exemptions under the laws of the
Commonwealth of Virginia and/or any other state, district or territory of the
United States.  Furthermore, if any Borrower shall default in the performance
when due of any of the provisions of this Agreement, the Agent, without notice
to or demand upon the Borrower (and without any grace or cure period) and
without waiving or releasing any of the Obligations or any default hereunder,
under the Notes or under any other Loan Document, may (but shall be under no
obligation to) perform the same for such Borrower's account, and any monies
expended in so doing shall be chargeable to the Borrowers with interest, at the
Default Rate, until the Event of Default is cured, and added to the indebtedness
secured by the Collateral.

       All sums paid or advanced by the Agent or any Lender in connection with
the foregoing or otherwise in connection with the Loan, and all court costs and
expenses of collection, including without limitation, reasonable attorneys' fees
and expenses (and fees and expenses resulting from the taking, holding or
disposition of the Collateral) incurred in connection therewith shall be paid by
the Borrowers upon demand and shall become a part of the Obligations secured by
the Collateral.  The Borrowers agree to bear the expense of each lien search,
property and judgment report or other form of Collateral ownership

                                      54
<PAGE>

investigation as the Agent in its discretion, shall deem necessary or desirable
to assure or further assure to the Agent its interests in the Collateral.

       Notwithstanding anything to the contrary set forth in this Agreement or
any other Loan Document, in the event that any Collateral proceeds shall have
been received by the Agent to pay any of the Obligations, such proceeds shall be
applied first to the Obligations relating to, arising from or incurred in
connection with the transactions contemplated by this Agreement in accordance
with the terms and provisions of this Agreement, and then to any other
Obligations of any Borrower.

                                  ARTICLE 10
                                  ----------

                               THE AGENT; AGENCY
                               -----------------

     Section 10.1  Appointment.  Each Lender hereby irrevocably appoints First
                   -----------
Union to act as the Agent for each such Lender pursuant to the provisions of
this Agreement and the other Loan Documents, and irrevocably authorizes the
Agent to take such action, and exercise such powers and perform such duties as
are expressly delegated to or required of the Agent by the terms hereof or
thereof, or are reasonably incidental thereto, including without limitation,
executing documents on behalf of the Lender(s), as agent. First Union agrees to
act as Agent on behalf of the Lender(s) on the terms and conditions set forth in
this Agreement and the other Loan Documents, subject to its right to resign as
provided in Section 10.10 of this Agreement. Each Lender agrees that the rights
and remedies granted to the Agent under this Agreement and the other Loan
Documents shall be exercised exclusively by the Agent, and that no Lender shall
have the right individually to exercise any such right or remedy, except to the
extent expressly provided herein or therein.

     Section 10.2  General Nature of the Agent's Duties.  Notwithstanding
                   ------------------------------------
anything to the contrary elsewhere in this Agreement or any other Loan Document:

          (a)  The Agent shall have no duties or responsibilities other than
those expressly set forth in this Agreement and the other Loan Documents, and no
implied duties or responsibilities on the part of the Agent shall be read into
this Agreement or any other Loan Document or shall otherwise exist.

          (b)  The duties and responsibilities of the Agent under this Agreement
and the other Loan Documents shall be mechanical and administrative in nature,
and the Agent shall not have a fiduciary relationship in respect of any Lender,
except with respect to funds or collateral it receives on behalf of any Lender.

          (c)  The Agent is and shall be solely the agent of the Lender(s). The
Agent does not assume, and shall not at any time be deemed to have, any
relationship of

                                      55
<PAGE>

agency or trust with or for, or any other duty or responsibility to, any
Borrower or any other person.

          (d)   The Agent shall be under no obligation to take any action
hereunder or under any other Loan Document if the Agent believes in good faith
that taking such action may conflict with any applicable law, or any provision
of this Agreement or any other Loan Document, or may require the Agent to
qualify to do business in any jurisdiction where it is not then so qualified.

     Section 10.3  Exercise of Powers.
                   ------------------

          (a)   The Agent shall have the authority to take any action of the
type specified in this Agreement or any other Loan Document as being within the
Agent's rights, powers or discretion, as it determines in its sole discretion,
except as provided in subsection (b) below, and except as provided in any other
Loan Document which expressly requires the direction or consent of (i) the
Required Lenders; or (ii) all of the Lenders, in either of which circumstances
the Agent shall not take such action absent such direction or consent. Any
action or inaction pursuant to such direction or consent shall be binding on all
of the Lenders.

          (b)   Except as otherwise expressly provided in this Agreement,
without the consent or approval of the Required Lenders, the Agent shall not, in
any material respect, amend, modify, grant consents or waive terms or provisions
of this Agreement or any other Loan Document (each, an "Amendment" and
collectively, "Amendments"), or declare an Event of Default, provide formal
written notice of an Event of Default to the Borrowers or exercise any rights or
remedies against any Borrower. Each Lender agrees that its decision to consent
to or reject any request by the Agent for any Amendment or for permission to
declare an Event of Default, provide formal notice thereof to the Borrowers
and/or exercise any rights or remedies arising by virtue of such default, shall
be made as soon as reasonably practicable after the Agent has provided all
information reasonably necessary to act on any such request, but in all events
within fifteen (15) Business Days of the receipt of such information; provided,
however, that in an emergency situation, the Agent may require the Lenders to
respond within such shorter time period as may be specified by the Agent in
writing, but in no event less than five (5) Business Days from the receipt of
such information. Unless otherwise provided herein, the Agent shall exercise any
and all rights and responsibilities on behalf of the Lenders in connection with
an Event of Default. Additionally, the consent or approval of all of the Lenders
shall be required for the Agent to (a) extend the final maturity of the Loan or
any Note, reduce the interest rate payable on or extend the time of payment for
any installment of principal, interest or fees payable in connection with the
Loan, or issue Letters of Credit (i) having an expiration date beyond the
Revolving Facility Maturity Date, except as otherwise expressly provided in this
Agreement, or (ii) causing the aggregate outstanding amount of all such Letters
of Credit issued to exceed Five Million Dollars ($5,000,000); (b) change the
Percentage of the Commitment Amount of any Lender, (c) release all or a
substantial portion of the

                                      56
<PAGE>

Collateral, except in accordance with the provisions of any applicable Loan
Document, (d) amend the definition of the Required Lenders or Maximum Borrowing
Base, expand the definitions of Eligible Billed Government Accounts Receivable,
Eligible Billed Commercial Accounts Receivable and/or Eligible Unbilled
Government Costs, or limit the definition of Ineligible Receivables, (e) consent
to the assignment or transfer by any Borrower of any of its rights or
obligations hereunder, (f) amend, modify or waive any provisions of this Section
10.3, (g) change the manner of application by the Agent of payments made under
the Loan Documents, or (h) change the method of calculation used in connection
with the computation of interest, commissions or fees. Each Lender agrees that
its decision to approve or reject any request for an amendment or waiver with
respect to this Agreement shall be made as soon as reasonably practicable after
the Lender has received all information deemed by the Agent to be necessary to
act on any such request. Notwithstanding anything to the contrary set forth in
this Article 10, (i) if at any time the vote of all of the Lenders shall be
required under this Agreement, then the vote of all of the Lenders (other than
Mass Mutual, acting in its capacity as a Note "B" Holder) shall be necessary,
except for any reduction to the interest rate payable under the Term Facility
"B" Note, any extension of the Term Facility "B" Maturity Date or any change to
the manner in which Mandatory Payments are to be applied to the Facilities (as
set forth in Section 1.5 of this Agreement), in which event the vote of all of
the Lenders (including Mass Mutual, acting in its capacity as a Note "B" Holder)
shall be required; and (ii) with respect to matters requiring the vote of the
Required Lenders, so long as Mass Mutual and First Union are not the only Lender
parties hereto and the Percentage of Mass Mutual (acting in its capacity as a
Note "B" Holder) and First Union (acting in its capacity as a Lender) equals or
exceeds, in the aggregate, fifty-one percent (51%) of the aggregate Commitment
Amount, such Percentages shall not be included in the calculation of the
required fifty-one percent (51%) of the aggregate Commitment Amount unless one
(1) of the other Lenders (excluding any Lender which is a subsidiary or
affiliate of, or related to, Mass Mutual or First Union) votes in the same
manner as Mass Mutual or First Union.

     Section 10.4  General Exculpatory Provisions. Notwithstanding anything to
                   ------------------------------
the contrary elsewhere in this Agreement or any other Loan Document:

          (a)  The Agent, in its capacity as Agent (but not as a Lender), shall
not be liable for any action taken or omitted to be taken by it under or in
connection with this Agreement or any other Loan Document, unless the same
constitutes gross negligence or willful misconduct, as finally determined by a
court of competent jurisdiction.

          (b)  The Agent, in its capacity as the Agent (but not a Lender), shall
not be responsible for (i) the execution, delivery, effectiveness,
enforceability, genuineness, validity or adequacy of this Agreement or any other
Loan Document, (ii) any recital, representation, warranty, document,
certificate, report or statement in this Agreement or any other Loan Document,
(iii) any failure of any Borrower or any Lender to perform any of their
respective obligations under this Agreement or any other Loan Document, (iv) the
existence, validity, enforceability, perfection, recordation, priority, adequacy
or value, now

                                      57
<PAGE>

or hereafter, of any lien or encumbrance or other direct or indirect security
afforded or purported to be afforded by any of the Loan Documents, or otherwise
from time to time, or (v) caring for, protecting, insuring or paying any taxes,
charges or assessments with respect to any Collateral.

          (c)  The Agent shall be under no obligation to ascertain, inquire or
give any notice relating to (i) the performance or observance of any of the
terms or conditions of this Agreement or any other Loan Document on the part of
any Borrower, (ii) the business, operations, condition (financial or otherwise)
or prospects of any Borrower, or (iii) except to the extent as may be set forth
in Section 10.5(f) of this Agreement, the existence of any Event of Default.

          (d)  The Agent shall be under no obligation, either initially or on a
continuing basis, to provide any Lender with any notices, reports or information
of any nature, whether in its possession presently or hereafter, except for such
notices, reports and other information expressly required by this Agreement or
any other Loan Document to be furnished by the Agent to such Lender; it being
understood and agreed that the Agent shall promptly deliver to each Lender
copies of any and all notices, documents, instruments and agreements deemed by
the Agent, in its reasonable discretion, to be material to the transactions
contemplated by this Agreement (including, without limitation, copies of any and
all field audit results and requests for the issuance of any Letter(s) of
Credit).

     Section 10.5  Administration by the Agent.
                   ---------------------------

          (a)  The Agent may rely upon any notice or other communication of any
nature (written or oral, including telephone conversations, whether or not such
notice or other communication is made in a manner permitted or required by this
Agreement or any other Loan Document) purportedly made by or on behalf of the
proper party or parties, and the Agent shall have no duty to verify the identity
or authority of any person giving such notice or other communication.

          (b)  The Agent may consult with legal counsel (including in-house
counsel for the Agent), independent public accountants and any other experts
selected by the Agent from time to time, and the Agent shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts.

          (c)  The Agent may conclusively rely upon the truth of the statements
and the correctness of the opinions expressed in any certificates or opinions
furnished to the Agent in accordance with the requirements of this Agreement or
any other Loan Document. Whenever the Agent shall deem it necessary or desirable
that a matter be proved or established with respect to any Borrower or any
Lender, such matter may (in the Agent's discretion) be established by a
certificate of such Borrower or such Lender, as the case may be, and the Agent
may conclusively rely upon such certificate.

                                      58
<PAGE>

          (d)  The Agent may fail or refuse to take any action unless it shall
be indemnified to its reasonable satisfaction from time to time against any and
all amounts, liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses and disbursements of every kind and nature
which may be imposed on, incurred by or asserted against the Agent by reason of
taking or continuing to take any such action; provided that no Lender shall be
obligated to indemnify the Agent for any portion of such amounts, liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements resulting solely from the gross negligence or willful
misconduct of the Agent, as finally determined by a court of competent
jurisdiction.

          (e)  The Agent may perform any of its duties under this Agreement or
any other Loan Document by or through agents or attorneys-in-fact. The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

          (f)  In the event that any Lender becomes aware (other than by written
notice from the Agent) that an Event of Default exists, such Lender shall
promptly provide written notice thereof to the Agent, as provided hereinbelow.
The Agent shall not be deemed to have any knowledge or notice of the occurrence
of any Event of Default (other than a default in the payment of regularly
scheduled principal or interest), unless the Agent has received from a Lender or
any Borrower a written notice referring to this Agreement, describing the Event
of Default, and stating that such notice is a "notice of default." If the Agent
receives such a notice from any Lender or Borrower, the Agent shall give prompt
notice thereof to each Lender.

          (g)  Except in emergency situations requiring immediate audits, as
determined by the Agent, the Agent shall provide three (3) Business Days prior
notice to the Lender(s) of any field audit scheduled to be performed by the
Agent pursuant to Section 1.6 of this Agreement. The Lender(s) shall be entitled
to (i) receive copies of field audits performed by the Agent, and (ii) accompany
the Agent to any field audit, provided that the Agent may, in its discretion,
limit the number of Lenders attending any such field audit.

     Section 10.6  Lenders Not Relying on the Agent or Other Lenders. Each
                   -------------------------------------------------
Lender acknowledges as follows:

          (a)  Neither the Agent nor any other Lender has made any
representations or warranties to it, and no act taken hereafter by the Agent or
any other Lender shall be deemed to constitute any representation or warranty by
the Agent or such other Lender to it.

          (b)  It has, independently and without reliance upon the Agent or any
other Lender, and based upon such documents and information as it has deemed

                                      59
<PAGE>

appropriate, made its own credit and legal analysis and decision to enter into
this Agreement and the other Loan Documents.

          (c)  It will, independently and without reliance upon the Agent or any
other Lender, and based upon such documents and information as it shall deem
appropriate at the time, make its own decisions to authorize the Agent to take
or not take action under or in connection with this Agreement and the other Loan
Documents.

     Section 10.7  Indemnification. Each Lender agrees to reimburse and
                   ---------------
indemnify the Agent and the Agent's directors, officers, employees and agents
(to the extent not reimbursed by any Borrower, and without limitation of the
obligation of the Borrowers to do so), ratably in accordance with each Lender's
Percentage, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs and
disbursements of every kind or nature (including the reasonable fees and
disbursements of counsel for the Agent or such other person in connection with
any investigative, administrative or judicial proceeding commenced or
threatened, whether or not the Agent or such other person shall be designated a
party thereto) that may at any time be imposed on, reasonably incurred by or
asserted against the Agent or such other person as a result of this Agreement,
any other Loan Document, any transaction from time to time contemplated hereby
or thereby, or any transaction financed in whole or in part, directly or
indirectly, with the proceeds of the Loan; provided that no Lender shall be
                                           --------
obligated to indemnify the Agent or such other person for any portion of such
amounts, losses, liabilities, claims, damages, expenses, obligations, penalties,
actions, judgments, suits, costs or disbursements resulting solely from the
gross negligence or willful misconduct of the person seeking indemnity, as
finally determined by a court of competent jurisdiction.

     Section 10.8  The Agent in its Individual Capacity.  With respect to its
                   ------------------------------------
commitments and the Obligations owing to it, First Union shall have the same
rights and powers under this Agreement and each other Loan Document as any other
Lender, and may exercise the same as though it was not the Agent.  The terms
"Lender," "holders of Notes" and like terms shall include First Union in its
individual capacity.  First Union and its affiliates may make loans to, accept
deposits from, acquire debt or equity interests in, act as trustee under
indentures of and engage in any other business with any Borrower and any
stockholder, subsidiary or affiliate of any Borrower, as though First Union was
not the Agent hereunder, and without liability to account to any other Lender
with respect to the same.

     Section 10.9  Holders of Notes. The Agent may deem and treat any Lender
                   ----------------
which is the payee of a Note as the owner and holder of such Note for all
purposes hereof unless and until written notice evidencing such transfer shall
have been filed with the Agent; it being understood and agreed that any such
transfer must comply with the requirements of Section 12.10(b) of this
Agreement. Any authority, direction or consent of any person who at the time of
giving such authority, direction or consent was a Lender

                                      60
<PAGE>

shall be conclusive and binding on each present and subsequent holder,
transferee or assignee of any Note or Notes payable to such Lender or issued in
exchange therefor.

     Section 10.10  Successor Agent.  The Agent may resign at any time by giving
                    ---------------
fifteen (15) days prior written notice thereof to the Lender(s) and the
Borrower, subject to appointment of a successor Agent (and such appointees
acceptance of appointment) as below provided in this Section 10.10.  Upon any
such resignation, the Required Lenders shall appoint another Lender as the
successor Agent; provided that such Lender is a commercial bank or trust company
organized under the laws of the United States of America or any State thereof
and has a combined capital and surplus of at least $1,000,000,000.  In such
event, the Agent's resignation shall not be effective until the successor Agent
shall have accepted its appointment.  Upon the acceptance by a successor Agent
of its appointment as Agent hereunder, such successor Agent shall thereupon
succeed to and become vested with all of the properties, rights, powers,
privileges and duties of the former Agent, without further act, deed or
conveyance.  Upon the effective date of resignation of a retiring Agent, such
Agent shall be discharged from its duties under this Agreement and the other
Loan Documents, but the provisions of this Agreement shall continue to inure to
its benefit as to any actions taken or omitted by it while it was Agent under
this Agreement.  If for any reason, at any time, there is no Agent hereunder,
then during such period, the Required Lenders shall have the right to exercise
the Agent's rights and perform its duties hereunder, except that (i) all notices
or other communications required or permitted to be given to the Agent shall be
given to each Lender, and (ii) with respect to the absence of the Agent, all
payments to be made to the Agent shall be made directly to the Lender for whose
account such payment is made (or to the Borrowers, if applicable).

     Section 10.11  Additional Agents. If the Agent shall from time to time deem
                    -----------------
it necessary or advisable to engage other agents for its own protection in the
performance of its duties hereunder or in the interests of the Lenders, then the
Agent and the Borrowers shall execute and deliver a supplemental agreement and
all other instruments and agreements necessary or advisable, in the opinion of
the Agent, to constitute another commercial bank or trust company, or one or
more other persons approved by the Agent, to act as co-Agent or a separate agent
with respect to any part of the Collateral, with such powers as may be provided
in such supplemental agreement, and with the power to vest in such bank, trust
company or other person (as such co-Agent or separate agent, as the case may
be), any properties, rights, powers, privileges and duties of such Agent under
this Agreement or any other Loan Document.

     Section 10.12  Calculations. The Agent shall not be liable for any
                    ------------
calculation, apportionment or distribution of payments made by it in good faith.
If such calculation, apportionment or distribution is subsequently determined to
have been made in error, the sole recourse of any Lender to whom payment was due
but not made shall be to recover from the Lenders any payment in excess of the
amount to which they are determined to be entitled, with interest thereon at the
Federal Funds Rate, or, if the amount due was not

                                      61
<PAGE>

paid by the Borrowers, to recover such amount from the Borrowers, with interest
thereon at the rate provided in the applicable Note.

     Section 10.13  Funding by Agent.
                    ----------------

          (a)  Except as otherwise expressly provided in this Agreement, the
Agent alone be entitled to make all advances in connection with the Loan and
shall receive all payments and other receipts relating to the Loan; it being
understood, however, that the Agent has reserved the right not to advance any
amounts to the Borrowers which the Agent has not received from the Lender(s).
The Agent will notify each Lender of the date and amount of any requested
advance, and if such notification is received by 1:00 p.m. Washington, D.C. time
on any given Business Day, the Lender(s) shall provide the required funds to the
Agent no later than the close of business on such Business Day. Once per week,
or within such shorter time frame as may be requested by the Agent, the Agent
and each Lender shall pay to each other such amounts (the "Equalization
Payments") as may be necessary to cause each Lender to own its applicable
Percentage of the Loan and otherwise implement the terms and provisions of this
Agreement; it being understood that (i) each Lender shall be entitled to receive
interest on amounts advanced by it only from the date of such Lender's advance
of funds; (ii) payments made by the Borrowers and received by the Agent shall be
promptly distributed to the Lenders in accordance with the terms of this
Agreement; and (iii) LIBOR advances and payments of amounts outstanding on a
LIBOR basis shall be made by and between the Agent and the applicable Lenders on
a same day basis, provided that the applicable Request for Advance, LIBOR
Election Form and Certification and/or payment of amounts outstanding on a LIBOR
basis shall have been received by the Agent on or before 1:00 p.m. Washington,
D.C. time on any given Business Day. The obligation of the Agent and each Lender
to make Equalization Payments shall not be affected by a bankruptcy filing by
any Borrower, the occurrence of any Event of Default or any other act,
occurrence or event whatsoever, whether the same occurs, before, on or after the
date on which an Equalization Payment is required to be made. All Equalization
Payments shall be made by 1:00 p.m. Washington, D.C. time on the date such
payment is required.

          (b)  Unless the Agent shall have been notified in writing by any
Lender no later than the close of business on the Business Day before the
Business Day on which an advance requested by the Borrowers is to be made, that
such Lender will not make its ratable share of such advance, the Agent may
assume that such Lender will make its ratable share of the advance, and in
reliance upon such assumption the Agent may (but in no circumstances shall be
required to) make available to the Borrowers a corresponding amount. If and to
the extent that any Lender fails to make such payment to the Agent when
required, such Lender shall pay such amount on demand (or, if such Lender fails
to pay such amount on demand, the Borrowers shall arrange for the repayment of
such amount to the Agent), together with interest for the Agent's own account
for each day from and including the date of the Agent's payment, to and
including the date of repayment to the Agent (before and after judgment).
Interest (a) if paid by such Lender

                                      62
<PAGE>

(i) for each day from and including the date of the Agent's payment to and
including the second Business Day thereafter, shall accrue at the Federal Funds
Rate for such day, and (ii) for each day thereafter, shall accrue at the rate or
rates per annum payable under the Notes; and (b) if paid by the Borrowers, shall
accrue at the rate or rates per annum payable under the Notes. All payments to
the Agent under this Section shall be made to the Agent at its office set forth
in the preamble of this Agreement (or as otherwise directed by the Agent), in
dollars, in immediately available funds, without set-off, withholding,
counterclaim or other deduction of any nature.

          (c)  All borrowings under this Agreement shall be incurred from the
Lenders pro rata on the basis of their respective Percentages of the applicable
Facility (except to the extent advanced (i) as a Swing Line Loan, or (ii) by the
Agent on behalf of any Lender as provided in subsection (a) or (b) above). It is
understood that no Lender shall be responsible for any other Lender's failure to
meet its obligation to make advances hereunder, and that each Lender shall be
obligated to make advances required to be made by it hereunder regardless of the
failure of any other Lender to make its advances hereunder.

          (d)  Each payment and prepayment received by the Agent for the account
of the Lenders shall be distributed first to the Swing Line Lender for
application to any Swing Line Outstandings, and then to each Lender entitled to
share in such payment, ratably in accordance with each Lender's Percentage;
provided, however, that (i) any payment or prepayment made with respect to
amounts outstanding under any Term Facility shall not be distributed first to
the Swing Line Lender for application to any Swing Line Outstandings; (ii) any
payment received by the Agent after the Acceleration Date shall be distributed
first to the Swing Line Lender for application to any Swing Line Outstandings,
and then to each Lender entitled to share in such payment, ratably based on the
aggregate outstanding principal amount of the Loans funded by such Lender,
together with any and all accrued and unpaid interest thereon, and (iii) any
Lender who shall be in default of its obligations set forth in this Agreement or
any other Loan Document or who has failed to fund its Percentage of any advance
under the Loan shall not be entitled to share in any such payment(s) until such
time as such default has been cured or such failure to fund, together with
interest thereon (as provided in subsection (b) above), has been paid to the
Agent in accordance with the terms and conditions of this Agreement or cured (as
the case may be). Payments from the Agent to the Lenders shall be made by wire
transfer in accordance with written instructions provided to the Agent by the
Lenders from time to time. Unless the Agent shall have received notice from the
Borrowers prior to the date on which any payment is due to the Lenders hereunder
that the Borrowers will not make such payment in full, the Agent may assume that
the Borrowers have made such payment in full on such date and the Agent, in
reliance upon such assumption, may cause to be distributed to each Lender on
such due date an amount equal to the amount then due such Lender. If and to the
extent the Borrowers shall not have made such payment in full to the Agent, each
Lender shall repay to the Agent upon its demand therefor such amount distributed
to such Lender, together with interest thereon at the overnight Federal Funds
Rate for each

                                      63
<PAGE>

day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Agent.

          (e)  If any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of setoff, or otherwise) in
excess of such Lender's Percentage of payments, such Lender shall forthwith
purchase from the other Lender(s) such participations in the Loans made by them
as shall be necessary to cause such purchasing Lender to share the excess
payment ratably with each of the other Lender(s); provided, however, if all or
any portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from the other Lender(s) shall be rescinded and each other
Lender shall repay to the purchasing Lender the purchase price to the extent of
such recovery, together with an amount equal to such Lender's ratable share
(according to the proportion of (1) the amount of such Lender's required
repayment, to (2) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount recovered. The Borrowers agree that any Lender purchasing a
participation from another Lender pursuant to this Section 10.13(e), to the
fullest extent permitted by law, may exercise all of its rights of payment with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrowers in the amount of such participation.

     Section 10.14  Benefit of Article. The provisions of this Article 10 are
                    ------------------
solely for the benefit of the Lenders. The Borrowers shall have no rights under
(or rights to require any Lender's compliance with) any of the provisions of
this Article 10; it being understood that the provisions of this Article 10 are
not in limitation of any right, power, duty, obligation or liability which the
Agent would have to or against any Borrower.

                   -----------------
the Agent as its agent and attorney-in-fact, with power of substitution, having
full power and authority, in its own name, in the name of any Borrower or
otherwise (but at the cost and expense of the Borrowers and without notice to
the Borrowers), to (i) notify account debtors obligated on any of the
Receivables to make payments thereon directly to the lockbox referenced in
Section 11.2 (if the lockbox shall have been established as required pursuant to
Section 11.2 of this Agreement), and to take control of the cash and non-cash
proceeds of any such Receivables, which right the Agent may exercise at any time
whether or not any Borrower is then in default hereunder or was theretofore
making collections thereon; (ii) charge against any bank account of any Borrower
any item of payment credited to the Collateral Account which is dishonored by
the drawee or the maker thereof; (iii) upon an Event of Default, compromise,

of the Collateral as the Agent may deem

                                      64

advisable; (iv) upon an Event of Default, release its interest in, make
exchanges or substitutions for and/or surrender, all or any part of any
Borrower's interest in all or any part of the Collateral; (v) upon an Event of
Default, remove from any Borrower's place(s) of business all books, records,

Event of Default, settle, renew, extend, compromise, compound, exchange or
adjust claims with respect to all or any part of the Collateral or any legal
proceedings brought with respect thereto; and (x) receive and open all mail
addressed to any Borrower, and if an Event of Default exists hereunder, notify
the Post Office authorities to change the address for the delivery of mail to
any Borrower to such address as the Agent may designate; it being understood
that the rights granted to the Agent in this clause (x), which are operative on
the occurrence of an Event of Default, shall not in any way limit or impair the
other rights provided to the Agent or any Lender in this Agreement or any other
Loan Document, including, without limitation, their rights with respect to the
Collateral Account and the below-referenced lockbox. Furthermore, each Borrower
hereby irrevocably appoints the Agent as its agent and attorney-in-fact, with
power of substitution, having full power and authority, in its own name, in the
name of the Agent, in the name of such Borrower or otherwise (but at the cost
and expense of the Borrowers and without notice to the Borrowers) and regardless
of whether an Event of Default has occurred or any act, event or condition which

charge against any banking account of any Borrower any item of payment credited
to any Borrower's account which is dishonored by the drawee or maker thereof;
and/or (iii) endorse the name of any Borrower upon any items of payment relating

Debtor.

     Section 11.2  Lockbox.  Each Borrower agrees that, upon the Agent's request
                   -------
following the occurrence of an Event of Default which has continued unremedied
beyond any applicable notice and/or cure period, the Borrowers shall establish
and continually maintain on terms and conditions reasonably satisfactory to the
Agent, one or more lockboxes (and, if required by the Agent, one or more blocked
accounts) for the collection of Receivables. Each Borrower hereby authorizes the
Agent to receive and collect any amount or amounts due or to become due on
account of any Receivables following the occurrence of an Event of Default and,
at its discretion, to apply the same to the repayment of the Notes. Except as
otherwise may be approved by the Agent in writing, any checks or other
remittances received by any Borrower in payment of the Receivables shall be held
in
                                      65

trust by such Borrower for the Agent and Lender(s).  Each Borrower shall, in
writing, within thirty (30) days from the date the Agent shall have requested
that one or more lockboxes be established and maintained, direct all of its
customers (other than certain customers as may be approved by the Agent in
writing) to make payments directly to the Agent pursuant to the form of Payment
Direction Letter attached as Exhibit 8 hereto, and shall include on all of its
                             ---------

     Section 11.3  Other Agreements. Except as may otherwise be expressly
                   ----------------
permitted by the terms of this Agreement, and without limiting any other
restrictions or provisions of this Agreement, each Borrower will (i) on demand,
subject to any confidentiality and secrecy requirements imposed by any
Government agency, make available in form reasonably acceptable to the Agent,
shipping documents and delivery receipts evidencing the shipment of goods which
gave rise to the sale or lease of inventory or of an account, contract right or
chattel paper, completion certificates or other proof of the satisfactory
performance of services which gave rise to the sale or lease of inventory or of
an account, contract right or chattel paper, and each Borrower's copy of any
written contract or order from which a sale or lease of inventory, an account,
contract right or chattel paper arose; and (ii) when requested, advise the Agent
when an Account Debtor returns or refuses to retain any goods, the sale or lease
of which gave rise to an account, contract right or chattel paper, and of any
delay in delivery or performance, or claims made in regard to any sale or lease
of inventory, account, contract right or chattel paper. Upon reasonable notice,
all such records will be available for examination by authorized agents of the
Agent.

     It is expressly understood and agreed, however, that neither the Agent nor
any Lender shall be required or obligated in any manner to make any inquiries as

any claims or take any other action to collect or enforce a payment of any
amounts which may have been assigned to it or to which it may be entitled
hereunder at any time or times.

insist upon the strict performance of any term, condition, covenant or agreement
set forth in this Agreement or any other Loan Document, or to exercise any
right, power or remedy consequent upon a breach thereof, shall constitute a
waiver of such term, condition, covenant or agreement or of any such breach, or
preclude the Agent or any Lender from exercising any such right, power or remedy
at any later time or times. By accepting payment after the due date of any of
the Obligations, neither the Agent nor any Lender shall be deemed to have waived
either the right to require prompt payment when due of all other Obligations, or
the right to declare a default for failure to make payment of any such other
Obligations.

     Section 12.4   Entire Agreement. This Agreement and the other Loan
                    ----------------

terms and provisions set forth in (i) the Commitment Letter and attached term
sheet with respect to the right of First Union and/or First Union Capital
Markets Corp., exercisable in connection with its syndication of the Loan, to
alter or amend the Loan, including, but not limited to any change in structure,

Union Capital Markets Corp. that will permit syndication of the Loan to the
satisfaction of First Union and/or First Union Capital Markets Corp., and (ii)
the Fee Letter, shall in each case survive the execution and delivery of this

force and effect for so long as any Borrower shall be indebted hereunder or
under any Note, and thereafter until the Agent shall have actually received
written notice of the termination hereof from the Borrowers and all Obligations
incurred or contracted before receipt of such notice shall have been fully paid.

     Section 12.5   Relationship of the Parties. This Agreement provides for the
                    ---------------------------
extension of financial accommodations by the Lender(s), in their capacity as
lender, to each Borrower, in its capacity as a borrower, and for the payment of
interest and repayment of the Obligations by the Borrowers. Certain provisions
herein, such as those relating to compliance with the financial covenants,
delivery to the Agent and/or Lender(s) of financial statements, and compliance
with other affirmative and negative covenants are for the benefit of the
Lender(s) to protect the interests of the Lender(s) in assuring repayment of the
Obligations. Nothing contained in this Agreement shall be construed as
permitting or obligating the Agent or any Lender to act as a financial or
business advisor or consultant to any Borrower, as permitting or obligating the
Agent or any Lender to control any Borrower or to conduct any Borrower's
operations, as creating any fiduciary obligation on the part of the Agent or any
Lender to any Borrower, or as creating any joint venture, agency or other
relationship between the parties other than as explicitly and specifically
stated in this Agreement. Each Borrower acknowledges that it has had the
opportunity to obtain the advice of experienced counsel of its own choosing in
connection with the negotiation and execution of this Agreement and to obtain
the advice of such counsel with respect to all matters contained herein,
including, without limitation, the provision in this Agreement for waiver of
trial by jury. Each Borrower further acknowledges that it is experienced with
respect to financial and credit matters and has made its own independent
decision to request the Obligations and execute and deliver this Agreement.

     Section 12.6   Waiver of Jury Trial; Punitive Damages. Each Borrower
                    --------------------------------------
hereby (a) covenants and agrees not to elect a trial by jury of any issue
triable by a jury, and (b) waives any right to trial by jury and any right to
claim punitive damages, in each case, fully to the extent that any such right
shall now or hereafter exist. This waiver of right to trial by jury and right to
claim punitive damages is separately given by each Borrower, knowingly and
voluntarily, and this waiver is intended to encompass individually each instance
and each issue as to which the right to a jury trial or any claim of punitive
damages would otherwise accrue. The Agent or any Lender is hereby authorized and
requested to submit this Agreement to any court having jurisdiction over the
subject matter and the parties hereto, so as to serve as conclusive evidence of
the Borrower's herein contained waiver of the right to jury trial and any right
to claim punitive damages. Further, each Borrower hereby certifies that no
representative or agent of the Agent or any Lender (including counsel for the
Agent and/or and Lender) has represented, expressly or otherwise, to the
undersigned that the Agent or any Lender will not seek to enforce this provision
waiving the right to a trial by jury or any right to claim punitive damages.

     Section 12.7   Submission to Jurisdiction; Service of Process; Venue. Any
                    -----------------------------------------------------
judicial proceeding brought against any Borrower with respect to this Agreement
or any other Loan Document may be brought in any court of competent jurisdiction
in the Commonwealth of Virginia, and by execution and delivery of this
Agreement, each party accepts for themselves and in connection with their
properties, generally and unconditionally, the non-exclusive jurisdiction of the
aforesaid court, and irrevocably agree to be bound by any judgment rendered by
such court in connection with this Agreement. Each Borrower irrevocably
designates and appoints AverStar whose address is 23 Fourth Avenue, Burlington,
Massachusetts 01803, as its agent to receive on its behalf service of all
process in any such proceeding in any court in the Commonwealth of Virginia,
such service being hereby acknowledged by each Borrower to be effective and
binding on it in every respect. A copy of any such process so served shall be
mailed by registered or certified mail to the Borrowers at the address to which
notices are to be addressed in accordance with this Agreement, except that any
failure to mail such copy shall not affect the validity of service of process.
Each Borrower shall at all times maintain an agent for service of process
pursuant to this provision. If any Borrower fails to appoint such an agent, or
if such agent refuses to accept service, such Borrower hereby agrees that
service upon it by mail shall constitute sufficient notice. Nothing herein shall
affect the right to serve process in any other manner permitted by law or shall
limit the right of the Agent or any Lender to bring proceedings against any
Borrower in the courts of any other jurisdiction.

     Section 12.8   Changes in Capital Requirements. If after the date of this
                    -------------------------------
Agreement any Lender shall determine that the adoption of any applicable law,
rule or regulation regarding capital adequacy, or any change therein, or any
change in the interpretation or administration thereof, or compliance by such
Lender with any request or directive regarding capital adequacy of any
authority, central bank or comparable agency, which adoption, change or
compliance has or would have the effect of reducing the rate of return on such
Lender's capital as a consequence of such Lender's obligations hereunder to

                                      69
<PAGE>

a level below that which such Lender could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's policies with
respect to capital adequacy), then the interest rate on the Notes shall be
increased to a rate which shall retain such Lender's original rate of return on
such Lender's capital.

     Section 12.9   Captions. The paragraph headings of this Agreement are for
                    --------
convenience of reference only, and in no way define, limit or describe the scope

                    -----------------------
term, condition, covenant or agreement hereof may be changed, waived, discharged
or terminated orally, but that may be accomplished only by an instrument in
writing signed by the party against whom enforcement of the change, waiver,
discharge or termination is sought.

                   ---------------
          (a)  No Borrower shall assign any of its rights, interests or
Obligations under this Agreement.

          (b)  No Lender shall sell, assign or otherwise transfer its interests
under this Agreement to any person or entity (other than an Eligible Assignee),

understood and agreed that the Borrowers' consent shall not be (i) unreasonably
withheld; or (ii) required if an Event of Default exists or any act, event or
condition has occurred which with notice or the lapse of time, or both, would
constitute an Event of Default. Furthermore, no sale, assignment or transfer
shall be made by any Lender (other than First Union) unless (i) if the proposed
assignee of the transferring Lender is not an affiliate of the transferring
Lender, at least thirty (30) days' prior written notice of such sale, assignment
or transfer shall have been issued by such transferring Lender to the Agent and
the Borrowers, and such notice identifies the proposed assignee; (ii) if the
proposed assignee of the transferring Lender is an affiliate of the transferring
Lender, written notice of such sale, assignment or transfer shall have been
issued by such transferring Lender to the Agent and the Borrowers simultaneously
with such sale, assignment or transfer, and such notice identifies the proposed
assignee; (iii) the dollar equivalent of the Percentage of the transferring
Lender being assigned equals or exceeds Five Million and No/100 Dollars
($5,000,000.00); (iv) the Agent shall have received a duly executed Assignment
and Acceptance agreement, in the form attached as Exhibit 9 hereto; and (v) if
                                                  ---------
the proposed assignee of the transferring Lender is not an affiliate of the
transferring Lender, an assignment fee in the amount of Five Thousand and No/100

contrary, determinations regarding the materiality of any act, event, condition
or circumstance shall be in the reasonable judgment of the Agent.
