PROSPECTUS SUMMARY

THIS SUMMARY IS QUALIFIED BY MORE DETAILED INFORMATION APPEARING IN OTHER
SECTIONS OF THIS PROSPECTUS. THE OTHER INFORMATION IS IMPORTANT, SO PLEASE READ
THIS ENTIRE PROSPECTUS CAREFULLY.

PEC SOLUTIONS

PEC Solutions provides professional technology services that enable
government entities to harness the power of the Internet and other advanced
technologies to enhance productivity and improve services to the public. We
migrate computer systems using older technologies and paper-intensive processes
to integrated electronic government solutions, which are referred to as
eGovernment solutions. We web-enable government by designing, building and
managing Internet-based solutions. Our solutions provide users with rapid and
easy access to large amounts of data and result in improved information flows
among government workers as well as between government entities and their
constituents.

We are a TOTAL solutions provider of eGovernment services addressing the
full technology lifecycle. We formulate technology strategies with our clients,
we create fully integrated technology solutions and we manage and enhance these
solutions over time. The substantial experience we have gained in the government
marketplace allows us to design and implement complex mission-critical solutions
that meet the unique challenges presented by our clients. Our eGovernment
solutions include:

- designing and developing technology strategies and web-enabled enterprise
system architectures;

- building and engineering complex intranets, extranets and other high
performance infrastructures;

- integrating older technology or "legacy" systems with web-based
applications;

- applying leading encryption security technologies; and

- deploying and operating automated enterprise management systems.

We serve clients at all levels of government. We have worked with
organizations representing every cabinet-level department of the federal
government. Our largest clients include federal organizations such as: the
Bureau of Alcohol, Tobacco and Firearms; the Drug Enforcement Administration;
the Immigration and Naturalization Service; the Internal Revenue Service; the
intelligence community; and the Veterans Benefits Administration. We also
provide services to various state and local government entities as well as
private sector organizations. Over the last five years, we have provided more
than $145 million worth of services in the government market and have increased
our revenues at approximately a 48% compound annual growth rate.

OUR MARKET OPPORTUNITY

The emergence of the Internet as a means of handling information presents
numerous opportunities for government to improve the way it communicates
internally and with its constituents. Procurement reform has paved the way for
government organizations to obtain outsourced technology services to apply the
Internet and related technologies to their functions. According to International
Data Corporation, overall government spending on information technology services
is expected to increase from $11.8 billion in 1997 to $17.3 billion in 2002.
Government spending on Internet services alone is expected to grow at
approximately a 56% compound annual rate, reaching $2.8 billion in 2003.

1
<PAGE>
We believe that the government market for technology services is unlike the
private sector market. Most agencies have made substantial investments in legacy
systems and are forced by budgetary constraints to update rather than replace
these systems. Government systems must handle extremely large amounts of data
for large and widely dispersed workforces. Governments require heightened
security to protect sensitive and personal information. In addition, agencies
must operate in a complex environment of strict government regulations.

OUR ADVANTAGE

Our focus on eGovernment solutions enables us to address an organization's
most difficult technology challenges. From the executive management level to our
project leaders, we employ people who have substantial government knowledge and
experience. We use our broad technical skills and capabilities to design
solutions that interface with, and often salvage, the significant investments
that were made in aging legacy systems. For portions of our business, we develop
reusable solution sets, enhanced through numerous client engagements, that allow
us to deliver results to our clients faster, cheaper and with greater
reliability.

OUR STRATEGY

We intend to:

- maintain our leading-edge position in emerging technologies such as the
Internet and advanced security;

- increase federal government market penetration;

- enhance our brand and culture to continue to attract and retain clients
and top quality professionals;

- expand into state and local government and selected highly-regulated
commercial markets; and

- undertake a disciplined acquisition program to broaden our client base,
service offerings and geographic presence.

RISK FACTORS

BEFORE YOU INVEST IN OUR COMMON STOCK, YOU SHOULD UNDERSTAND THAT SUCH AN
INVESTMENT INVOLVES RISK. YOU SHOULD CAREFULLY CONSIDER THESE RISK FACTORS AS
WELL AS ALL OF THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE YOU
DECIDE TO PURCHASE SHARES OF OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS
ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION AND OPERATING RESULTS COULD BE
ADVERSELY AFFECTED. IN SUCH CASE, THE TRADING PRICE OF OUR COMMON STOCK COULD
DECLINE AND YOU MIGHT LOSE ALL OR PART OF YOUR INVESTMENT.

RISKS RELATED TO OUR BUSINESS

SUBSTANTIALLY ALL OF OUR REVENUES WOULD BE THREATENED IF OUR RELATIONSHIPS
WITH AGENCIES OF THE FEDERAL
GOVERNMENT WERE HARMED

Our largest clients are agencies of the federal government. If the federal
government in general, or any significant government agency, uses less of our
services or terminates its relationship with us, our revenues could decline
substantially, and our business could be seriously harmed. During 1999,
contracts with the federal government and contracts with prime contractors of
the federal government accounted for approximately 96% of our revenues. During
that same period, our ten largest clients, all agencies of the federal
government, generated approximately 60% of our revenues, with the top five
clients accounting for 40% of our revenues. We believe that federal government
contracts are likely to continue to account for a significant portion of our
revenues for the foreseeable future. The volume of work that we perform for a
specific client, however, is likely to vary from year to year, and a significant
client in one year may not use our services as extensively, or at all, in a
subsequent year.

OUR GOVERNMENT CONTRACTS MAY BE TERMINATED PRIOR TO THEIR COMPLETION, AND IF
WE DO NOT REPLACE THEM, OUR OPERATING RESULTS MAY BE HARMED

We derive substantially all of our revenues from government contracts that
typically are awarded through competitive processes and span a one year base
period and one or more option years. The unexpected termination or nonrenewal of
one or more of our significant contracts could result in significant revenue
shortfalls. Our clients generally have the right not to exercise the option
periods. In addition, our contracts typically contain provisions permitting an
agency to terminate the contract on short notice, with or without cause.

Following termination, if the client requires further services of the type
provided in the contract, there is frequently a competitive rebidding process.
We may not win any particular rebid or be able to successfully bid on new
contracts to replace those that have been terminated. Even if we do win the
rebid, we may experience revenue shortfalls in periods where we anticipated
revenues from the contract rather than its termination and subsequent rebidding.
These revenue shortfalls could harm operating results for those periods.

OUR LACK OF LONG-TERM CONTRACTS WITH CLIENTS AND OUR RELATIVELY FIXED
OPERATING EXPENSES EXPOSE US TO GREATER
RISK OF INCURRING LOSSES

Our clients retain us on an engagement-by-engagement basis, rather than
under long-term contracts. We incur costs based on our expectations of future
revenues. Our operating expenses are relatively fixed and cannot be reduced on
short notice to compensate for unanticipated variations in the number or size of
engagements in progress. These factors make it difficult for us to predict our
revenues and operating results. If we fail to predict our revenues accurately,
it may seriously harm our financial condition and results of operation.

5
<PAGE>
A REDUCTION IN OR THE TERMINATION OF OUR SERVICES COULD LEAD TO
UNDERUTILIZATION OF OUR EMPLOYEES AND COULD HARM OUR OPERATING RESULTS

Our employee compensation expenses are relatively fixed. Therefore, if a
client defers, modifies or cancels an engagement or chooses not to retain us for
additional phases of a project, our operating results will be harmed unless we
can rapidly redeploy our employees to other engagements in order to minimize
underutilization.

FAILING TO MAINTAIN STRONG RELATIONSHIPS WITH PRIME CONTRACTORS COULD RESULT
IN A DECLINE IN OUR REVENUES

We derived approximately 40% of our revenues during 1999 through our
relationships with prime contractors, which, in turn, have contractual
relationships with end-clients. One of our prime contractors, Unisys, accounted
for 24% of our revenues during 1999. We expect to continue to depend on these
relationships for a material portion of our revenues in the foreseeable future.
If any of these prime contractors eliminate or reduce their engagements with us,
or have their engagements eliminated or reduced by their end-clients, we will
lose a source of revenues, which, if not replaced, will adversely affect our
operating results.

WE MUST RECRUIT AND RETAIN QUALIFIED PROFESSIONALS TO SUCCEED IN OUR
LABOR-INTENSIVE BUSINESS

Our future success depends in large part on our ability to recruit and
retain qualified professionals skilled in complex information technology
services and solutions, including encryption and other security systems. Such
personnel are in great demand and are likely to remain a limited resource in the
foreseeable future. Competition for qualified professionals is intense. Any
inability to recruit and retain a sufficient number of these professionals could
hinder the growth of our business.

WE MAY LOSE MONEY ON FIXED-PRICE CONTRACTS IF WE MISCALCULATE THE RESOURCES WE
NEED TO COMPLETE THE CONTRACT

We derived approximately 23% of our revenues in 1999 from fixed-price
contracts. We anticipate a material portion of our future engagements will
continue to be contracted at a fixed price. Unlike time and materials contracts,
for which we are reimbursed based on our actual expenditures of resources,
fixed-price contracts require us to price our contracts by predicting our
expenditures in advance. If we miscalculate the resources we need to complete
fixed-price engagements, our operating results could be seriously harmed because
we are not compensated for the higher costs. The risk that we may miscalculate
the resources we need is higher because we work with complex technologies in
compressed time frames.

WE COULD LOSE REVENUES AND CLIENTS AND EXPOSE OUR COMPANY TO LIABILITY IF WE
FAIL TO MEET CLIENT EXPECTATIONS

We create, implement and maintain technology solutions that are often
critical to our clients' operations. If our technology solutions or other
applications have significant defects or errors or fail to meet our clients'
expectations, we may:

- lose revenues due to adverse client reaction;

- be required to provide additional remediation services to a client at no
charge;

- receive negative publicity, which could damage our reputation and
adversely affect our ability to attract or retain clients; and

- suffer claims for substantial damages against us, regardless of our
responsibility for the failure.

While many of our contracts limit our liability for damages that may arise
from negligent acts, errors, mistakes or omissions in rendering services to our
clients, we cannot be sure that these contractual provisions will protect us
from liability for damages if we are sued. Furthermore, our general liability
insurance coverage may not continue to be available on reasonable terms or in
sufficient amounts to cover one or more large claims, or the insurer may
disclaim coverage as to any future claim. The successful assertion of any large
claim against us could seriously harm our business. Even if not successful, such
claims could result in significant legal and other costs and may be a
distraction to management.

6
<PAGE>
SECURITY BREACHES IN SENSITIVE GOVERNMENT SYSTEMS COULD RESULT IN THE LOSS OF
CLIENTS AND NEGATIVE PUBLICITY

Many of the systems we develop involve managing and protecting information
involved in law enforcement and other sensitive government functions. A security
breach in one of these systems could cause serious harm to our business, could
result in negative publicity and could prevent us from having further access to
such critically sensitive systems or other similarly sensitive areas for other
governmental clients. Losses that we could incur from such a security breach
could exceed the policy limits that we have for "errors and ommissions" or
product liability insurance.

IF WE CANNOT OBTAIN THE NECESSARY SECURITY CLEARANCES, WE MAY NOT BE ABLE TO
PERFORM CLASSIFIED WORK FOR THE GOVERNMENT AND OUR REVENUES MAY SUFFER

Government contracts require us, and some of our employees, to maintain
security clearances. If we lose or are unable to obtain security clearances, the
client can terminate the contract or decide not to renew it upon its expiration.
As a result, to the extent we cannot obtain the required security clearances for
our employees working on a particular engagement, we may not derive the revenue
anticipated from the engagement, which, if not replaced with revenue from other
engagements, could seriously harm our operating results.

WE DEPEND ON OUR SENIOR MANAGEMENT TEAM, AND THE LOSS OF ANY MEMBER MAY
ADVERSELY AFFECT OUR ABILITY TO OBTAIN AND MAINTAIN CLIENTS

We believe that our success will depend on the continued employment of our
senior management team, including David Karlgaard, our Chief Executive Officer,
Paul Rice, our Chief Operating Officer and Alan Harbitter, our Chief Technology
Officer. We have key man life insurance policies that cover Messrs. Karlgaard
and Rice up to $1 million and Mr. Harbitter up to $500,000. This dependence is
particularly important to our business because personal relationships are a
critical element of obtaining and maintaining client engagements. If one or more
members of our senior management team was unable or unwilling to continue in
their present positions, such persons would be difficult to replace and our
business could be seriously harmed. Furthermore, clients or other companies
seeking to develop in-house capabilities may hire away some of our key
employees. Employee defections to clients or competitors would not only result
in the loss of key employees but could also result in the loss of a client
relationship or a new business opportunity. Any losses of client relationships
could seriously harm our business.

WE MAY NOT BE ABLE TO SUCCESSFULLY IDENTIFY, MANAGE AND INTEGRATE FUTURE
ACQUISITIONS, WHICH MAY HARM OUR OPERATING RESULTS

We may use a portion of the proceeds from this offering to acquire companies
or businesses that are complementary to ours. However, we have no immediate
plans or current agreements to acquire any additional companies or businesses,
and we cannot assure you that we will identify appropriate acquisition
candidates. If we do identify an appropriate acquisition candidate, we cannot
assure you that we would be able to successfully negotiate the terms of an
acquisition, finance the acquisition or integrate the acquired business into our
existing business. Negotiations of potential acquisitions and the integration of
an acquired business could disrupt our business by diverting management away
from day-to-day operations. Further, failure to successfully integrate any
acquisition may cause significant operating inefficiencies and adversely affect
our profitability. Consummating a merger could require us to raise additional
funds through additional equity or debt financing. Additional equity financing
could result in further dilution of the per share value of your stock.
Additional debt financing could force us to accept contractual limitations that
could harm our ability to grow.

7
<PAGE>
AUDITS OF OUR GOVERNMENT CONTRACTS MAY RESULT IN A REDUCTION IN REVENUES WE
RECEIVE FROM THOSE CONTRACTS OR MAY RESULT IN CIVIL OR CRIMINAL PENALTIES THAT
COULD HARM OUR REPUTATION

Federal 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.
An audit could result in a substantial adjustment to our revenues because any
costs found to be improperly allocated to a specific contract will not be
reimbursed, while improper costs already reimbursed must be refunded. 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, forfeiture of profits, suspension of payments, fines and
suspension or debarment from doing business with federal government agencies. In
addition, we could suffer serious reputational harm if allegations of
impropriety were made against us.

WE MAY BE LIABLE FOR PENALTIES UNDER A VARIETY OF PROCUREMENT RULES AND
REGULATIONS, AND CHANGES IN GOVERNMENT REGULATIONS COULD SLOW OUR GROWTH OR
REDUCE OUR PROFITABILITY

We must comply with and are affected by federal government regulations
relating to the formation, administration and performance of government
contracts. These regulations affect how we do business with our clients and may
impose added costs on our business. Any failure to comply with applicable laws
and regulations could result in contract termination, price or fee reductions or
suspension or debarment from contracting with the federal government. Further,
the federal government may reform its procurement practices or adopt new
contracting methods relating to the GSA schedule or other government-wide
contract vehicles. If we are unable to successfully adapt to those changes, our
business could be seriously harmed.

OUR FAILURE TO ADEQUATELY PROTECT OUR CONFIDENTIAL INFORMATION AND PROPRIETARY
RIGHTS MAY HARM OUR COMPETITIVE POSITION

While our employees execute confidentiality agreements, we cannot guarantee
that this will be adequate to deter misappropriation of our confidential
information. In addition, we may not be able to detect unauthorized use of our
intellectual property in order to take appropriate steps to enforce our rights.
If third parties infringe or misappropriate our copyrights, trademarks or other
proprietary information, our competitive position could be seriously harmed. In
addition, other parties may assert infringement claims against us or claim that
we have violated their intellectual property rights. Such claims, even if not
true, could result in significant legal and other costs and may be a distraction
to management. While we have applied for trademarks for PEC.com, PEC, PEC
Solutions, Web-enabling Government and the related symbols and designs, we
cannot assure you that these trademarks will be granted.

RISKS RELATED TO THE EGOVERNMENT SOLUTIONS MARKET

COMPETITION COULD RESULT IN PRICE REDUCTIONS, REDUCED PROFITABILITY AND LOSS
OF MARKET SHARE

Competition in the market for eGovernment solutions is intense. If we are
unable to differentiate our services from those of our competitors, our revenue
growth and operating margins may decline. Many of our competitors are larger and
have greater financial, technical, marketing and public relations resources,
larger client bases and greater brand or name recognition than us. Our larger
competitors may be able to provide clients with additional benefits, including
reduced prices. We may be unable to meet those prices, which may cause us to
lose business and market share. Alternatively, we could decide to meet the lower
prices, which could harm our profitability. If we fail to compete successfully,
our business could be seriously harmed.

8
<PAGE>
Our current competitors include, and may in the future include, the
following:

- information technology services providers and large government contractors
such as American Management Systems, Andersen Consulting, Booz-Allen &
Hamilton, Computer Sciences Corporation, Electronic Data Systems, KPMG,
PricewaterhouseCoopers, Science Applications International Corporation and
Unisys; and

- Internet professional services providers.

Current and potential competitors also have established or may establish
cooperative relationships among themselves or with third parties to increase
their ability to address client needs. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. In addition, some of our competitors may develop
services that are superior to, or have greater market acceptance than, the
services that we offer.

OUR BUSINESS WILL BE HARMED IF GOVERNMENT AGENCIES ARE UNWILLING TO REPLACE OR
SUPPLEMENT EXPENSIVE LEGACY SYSTEMS

Government agencies have spent substantial resources over an extended period
of time to develop computer systems and to train their personnel to use them.
These agencies may be reluctant to abandon or supplement these legacy systems
with Internet and other advanced technology systems because of the cost of
developing them or the additional cost of re-training their personnel. Such
reluctance would make it more difficult to acquire new engagements which would
harm our business prospects.

OUR GROWTH WILL BE HARMED IF A VIABLE MARKET FOR EGOVERNMENT SERVICES IS NOT
SUSTAINED

We cannot be certain that a viable government market for Internet and other
advanced technology services will be sustainable. If this market is not
sustained and we are unable to refocus our services on the private sector market
or other in-demand technologies, our growth would be negatively affected.
Although government agencies have recently increased focus on and funding for
technology initiatives, we cannot be certain that these initiatives will
continue in the future. Budget cutbacks or political changes could result in a
change of focus or reductions in funding for technology initiatives, which, in
turn, could seriously harm our revenues.

UNDISCOVERED YEAR 2000 PROBLEMS COULD NEGATIVELY AFFECT OUR CLIENTS' SYSTEMS,
WHICH COULD HARM OUR REVENUES AND OUR REPUTATION

Although we have not experienced any significant failures or problems in
connection with the Year 2000 date change in either our software or the systems
we have developed for our clients, our clients may still experience significant
problems that may require them to divert significant resources to remediation
instead of to eGovernment solutions. This could delay our ability to generate
new business and additional revenues.

Furthermore, undiscovered Year 2000 problems may also affect software or
code that we develop or third-party software products that are incorporated into
the information systems solutions we create for our clients. Our clients license
software directly from third parties, and we do not guarantee that the software
licensed from these suppliers is Year 2000 compliant. However, any failure on
our part to provide Year 2000 compliant information systems solutions to our
clients could result in financial loss, harm to our reputation and liability to
others and could seriously harm our business, financial condition and operating
results.

RISKS RELATED TO THE OWNERSHIP OF OUR COMMON STOCK

OUR QUARTERLY REVENUES AND OPERATING RESULTS COULD BE VOLATILE AND MAY CAUSE
OUR STOCK PRICE TO FLUCTUATE

Our quarterly revenues and operating results may fluctuate significantly in
the future. In particular, if the Federal government does not adopt a budget for
its fiscal year beginning on October 1, Federal agencies may be forced to
suspend our contracts due to a lack of funding. Consequently, we may realize
lower revenues in the quarter ending December 31. Further, the rate at which the
Federal government procures technology may be negatively affected following
changes in Presidential administrations and in senior government officials. As a
result, our operating results could be volatile and difficult to predict and
period-to-period comparisons of our operating results may not be a good
indication of our future performance.

A significant portion of our operating expenses, such as personnel and
facilities costs, are fixed in the short term. Therefore, any failure to
generate revenues according to our expectations in a particular quarter could
result in reduced income in the quarter. In addition, our quarterly operating
results may not meet the expectations of securities analysts or investors, which
in turn may have an adverse effect on the market price of our common stock.

OUR OFFICERS AND DIRECTORS WILL OWN 82.4% OF OUR STOCK AND COULD CONTROL
MATTERS SUBMITTED TO STOCKHOLDERS FOR THEIR APPROVAL

Upon completion of this offering, our directors and executive officers will
beneficially own, in the aggregate, 82.4% of our outstanding common stock, or
80.1% if the underwriters exercise their over-allotment option in full. As a
result, these stockholders will be able to exercise control over all matters
requiring stockholder approval, including the election of directors and approval
of significant corporate transactions. This concentration of ownership may also
have the effect of delaying or preventing a change in control of PEC Solutions.

WE HAVE VARIOUS MECHANISMS IN PLACE THAT MAY PREVENT A CHANGE IN CONTROL THAT
STOCKHOLDERS MAY CONSIDER FAVORABLE

Our certificate of incorporation and bylaws may discourage, delay or prevent
a change in control of PEC Solutions that stockholders may consider favorable.
Our certificate of incorporation and bylaws:

- authorize the issuance of blank check capital stock that could be issued
by our board of directors to thwart a takeover attempt;

- classify the board of directors into staggered, three-year terms, which
may lengthen the time required to gain control of our board of directors;

- prohibit cumulative voting in the election of directors, which would
otherwise allow holders of less than a majority of the stock to elect some
directors;

- require super-majority voting to effect amendments to provisions of our
bylaws concerning the number of directors;

- limit who may call special meetings of stockholders;

- prohibit stockholder action by written consent, requiring all actions to
be taken at a meeting of the stockholders;

- establish advance notice requirements for nominating candidates for
election to the board of directors or for proposing matters that can be
acted upon by stockholders at stockholder meetings; and

- require that vacancies on the board of directors, including newly-created
directorships, be filled only by a majority vote of directors then in
office.

<PAGE>
In addition, Section 203 of the Delaware General Corporation Law may
discourage, delay or prevent a change in control by prohibiting PEC Solutions
from engaging in a business combination with an interested stockholder for a
period of three years after the person becomes an interested stockholder. See
"Description of Our Capital Stock--Anti-Takeover Effects of Our Certificate of
Incorporation and Bylaws and Delaware General Corporation Law."

PURCHASERS IN THIS OFFERING WILL EXPERIENCE IMMEDIATE DILUTION AS THE NET
TANGIBLE BOOK VALUE OF THE SHARES OF COMMON STOCK WILL BE SUBSTANTIALLY LOWER
THAN THE OFFERING PRICE

The initial public offering price of the shares of common stock is
substantially higher than the net tangible book value per share of the
outstanding common stock. As a result, if we were liquidated for book value
immediately following this offering, each stockholder purchasing in this
offering would experience immediate dilution of $7.79 per share of common stock.
Dilution is the difference between the offering price per share and the net
tangible book value per share of our common stock. See "Dilution" for a
discussion about how net tangible book value is calculated. Existing
stockholders will have an aggregate unrealized gain of $176.3 million.

EXISTING STOCKHOLDERS CAN SELL A SUBSTANTIAL AMOUNT OF THEIR SHARES IN THE
PUBLIC MARKET AFTER THIS OFFERING, WHICH COULD DEPRESS OUR STOCK PRICE AND
MAKE IT MORE DIFFICULT FOR US TO RAISE CAPITAL

Sales of a substantial number of shares of our common stock, including
shares issued upon the exercise of outstanding options, in the public market
after this offering could cause the market price of our common stock to fall. A
decline in our stock price could impair our ability to raise capital through the
sale of additional equity securities. For a description of the shares of our
common stock that are available for future sale, see "Shares Eligible for Future
Sale."

USE OF PROCEEDS

The net proceeds from the sale of the 3,500,000 shares of common stock
offered by us will be approximately $31.7 million, based on an assumed initial
public offering price of $10.00 per share and after deducting the underwriting
discounts and commissions and estimated offering expenses. We will not receive
any proceeds from the 525,000 shares to be sold by the selling stockholders if
the underwriters exercise their over-allotment option.

The primary purposes of this offering are to create a public market for our
common stock, to improve the incentive mechanism for our professionals through
stock options, to obtain additional equity capital and to facilitate future
access to public markets. We expect to use the net proceeds from this offering
for general corporate purposes, including working capital. Management will have
broad discretion in the allocation of the net proceeds. We may also use a
portion of the net proceeds to acquire businesses that are complementary to
ours. We have no current plans, agreements or commitments for, and are not
currently engaged in any negotiations with respect to, any such transaction.
Pending their use, the proceeds of this offering will be invested in short-term,
investment grade, interest-bearing securities.

DIVIDEND POLICY

Prior to this offering, we have declared and paid annual cash dividends on
our capital stock. In January 1999 and January 2000, we paid dividends of $0.02
and $0.023 per share, respectively. After this offering, we expect to retain
future earnings, if any, for use in the operation and expansion of our business
and do not anticipate paying any further cash dividends in the foreseeable
future. Our board of directors will determine whether to pay dividends in the
future based on conditions then existing, including our earnings, financial
conditions and capital requirements, as well as economic and other conditions as
the board of directors may deem relevant.

DILUTION

Our net tangible book value as of December 31, 1999, was $15.2 million or
$0.86 per share. Net tangible book value is the amount of total tangible assets
less total liabilities. Net tangible book value per share is net tangible book
value divided by the number of shares of common stock outstanding.

Dilution to new investors represents the difference between the amount per
share paid by purchasers of common stock in this offering and the net tangible
book value per share of common stock immediately after completion of this
offering. Following the sale of common stock in this offering at an assumed
initial public offering price of $10.00 per share, our net tangible book value
as of December 31, 1999, would have been $46.8 million, or $2.21 per share. This
represents an immediate increase in net tangible book value of $1.35 per share
to our existing stockholders, and an immediate dilution in net tangible book
value of $7.79 per share to purchasers of common stock in this offering. The
following table illustrates this per share dilution.

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

THE FOLLOWING SECTION SHOULD BE READ IN CONJUNCTION WITH THE "SELECTED
HISTORICAL FINANCIAL DATA" AND OUR FINANCIAL STATEMENTS AND THE NOTES THERETO
INCLUDED ELSEWHERE IN THIS PROSPECTUS. IN ADDITION TO HISTORICAL INFORMATION,
THIS DISCUSSION AND ANALYSIS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS, UNCERTAINTIES AND ASSUMPTIONS WHICH COULD CAUSE ACTUAL RESULTS TO DIFFER
MATERIALLY FROM MANAGEMENT'S EXPECTATIONS. FACTORS THAT COULD CAUSE SUCH
DIFFERENCES INCLUDE THOSE DISCUSSED IN "RISK FACTORS."

OVERVIEW

PEC Solutions is a professional services firm specializing in high-end
solutions that help government organizations capitalize on the Internet and
other advanced technologies. We migrate paper-intensive procedures to
web-enabled processes using eGovernment solutions that help our clients enhance
their productivity and improve the services they offer to the public. As a total
solutions provider, we address the full technology lifecycle, including
formulating technology strategies, creating business solutions, performing
long-term operational management and continuing enhancement of the solution.

We derive substantially all of our revenues from fees for consulting
services. We generate these fees from contracts with various payment
arrangements, including time and materials contracts, fixed-price contracts and
cost-reimbursable contracts. During 1999, revenues from these contract types
were approximately 62%, 23% and 15%, respectively, of total revenues. We
typically issue invoices monthly to manage outstanding accounts receivable
balances. We recognize revenues on time and materials contracts as the services
are provided. We recognize revenues on fixed-price contracts using the
percentage of completion method as services are performed over the life of the
contract, based on the costs we incur in relation to the total estimated costs.
We recognize and make provisions for any anticipated contract losses at the time
we know and can estimate them. Fixed-price contracts are attractive to clients,
and while subject to increased risks, provide opportunities for increased
margins. We recognize revenues on cost-reimbursable contracts as services are
provided. These revenues are equal to the costs incurred in providing these
services plus a proportionate amount of the fee earned. We have historically
recovered all of our costs on cost-reimbursable contracts, which means we have
lower risk and our margins are lower on these contracts.

Our historical revenue growth is attributable to various factors, including
an increase in the size and number of projects for existing and new clients.
Existing clients from the previous year generated approximately 96% of our
revenues in 1999 and approximately 95% of our revenues in 1998. We have also
expanded our geographic presence by opening offices in Baltimore, Maryland and
Denver, Colorado. As of December 31, 1999, we had 429 employees.

Our most significant expense is direct costs, which consist primarily of
project personnel salaries and benefits, and direct expenses incurred to
complete projects. Our direct costs as a percentage of revenues are also related
to the utilization rate of our consulting employees. We manage utilization by
frequently monitoring project requirements and timetables. The number of
consulting employees assigned to a project will vary according to the size,
complexity, duration and demands of the project.

General and administrative expenses consist primarily of costs associated
with our executive management, finance and administrative groups, human
resources, unassigned consulting employees,

17
<PAGE>
employee training, occupancy costs, depreciation and amortization, travel, and
all other branch and corporate costs.

Sales and marketing expenses include the costs of sales and marketing
personnel and costs associated with marketing and bidding on future projects.

Other income consists primarily of interest income earned on our cash, cash
equivalents and marketable securities.

RESULTS OF OPERATIONS

The following table sets forth certain financial data as a percentage of
revenues for the periods indicated.

</TABLE>

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

(a) Gross profit represents revenues less direct costs, which consist primarily
of project personnel salaries and benefits and direct expenses incurred to
complete projects.

1999 COMPARED WITH 1998

REVENUES. Revenues increased 28.3% to $53.2 million for 1999 from
$41.5 million for 1998. The increase in revenue primarily reflects an increase
in the amount of services to existing clients, $11.5 million, and new clients,
$0.2 million. Our individual tasks average six to ten months in length and are
continually replaced with new tasking from our clients.

DIRECT COSTS. Direct costs increased 27.3% to $30.4 million for 1999 from
$23.5 million for 1998. The increase was due primarily to an increase in project
personnel to 382 as of December 31, 1999, as compared with 312 as of
December 31, 1998. As a service provider, our direct costs increase in
conjunction with our increased revenues. Direct costs increased as a percentage
of revenues to 57.2% for 1999 from 56.7% for 1998. This increase was principally
related to normal fluctuations in labor and other direct costs.

GROSS PROFIT. Gross profit increased 27.0% to $22.8 million for 1999 from
$17.9 million for 1998. Gross profit as a percentage of revenues decreased to
42.8% for 1999 from 43.3% for 1998 because direct costs grew at a faster rate
than revenues. This resulted from normal fluctuations in labor and other direct
costs.

18
<PAGE>
GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
increased 22.0% to $12.0 million for 1999 from $9.8 million for 1998. These
expenses grew at a rate less than the growth rate in revenues and direct costs.
These costs, such as rent and other facility costs, recruiting expenses and
depreciation of equipment purchased, were related to the increase in project
personnel. Our total general and administrative headcount increased to 47
employees as of December 31, 1999 compared to 34 employees as of December 31,
1998. Facilities costs also increased for 1999 due to the opening of our new
offices in Fairfax County, Virginia, Baltimore, Maryland and Denver, Colorado.
We expect to incur increased facilities costs in connection with opening our new
headquarters facility in Fairfax County. We expect general and administrative
expenses to increase in absolute dollars in part due to the costs associated
with being a public company.

SALES AND MARKETING. Sales and marketing expenses increased 49.0% to
$1.8 million for 1999 from $1.2 million for 1998. This increase was due to an
increase in our marketing staff and our marketing efforts. We expect to increase
marketing costs in order to increase our revenue stream.

OPERATING INCOME. Operating income increased 30.3% to $9.0 million for 1999
from $6.9 million for 1998.

1998 COMPARED WITH 1997

REVENUES. Revenues increased 68.3% to $41.5 million in 1998 from
$24.6 million in 1997. The increase in revenues primarily reflects an increase
in the volume of services to existing clients.

DIRECT COSTS. Direct costs increased 69.5% to $23.5 million in 1998 from
$13.9 million in 1997. The increase was due primarily to an increase in project
personnel to 312 as of December 31, 1998 as compared to 188 as of December 31,
1997. Direct costs increased as a percentage of revenues to 56.7% in 1998 from
56.3% in 1997 due to normal fluctuations in labor and other direct costs.

GROSS PROFIT. Gross profit increased 66.8% to $17.9 million in 1998 from
$10.8 million in 1997. Gross profit as a percentage of revenues decreased to
43.3% in 1998 from 43.7% in 1997 as direct costs grew at a faster rate than
revenues due to an increase in personnel costs.

GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
increased 60.6% to $9.8 million in 1998 from $6.1 million in 1997. These
expenses grew at a rate less than the growth rate in revenues and direct costs.
Additionally, our total general and administrative headcount increased to 34
employees as of December 31, 1998 compared to 26 employees as of December 31,
1997.

SALES AND MARKETING. Sales and marketing expenses increased 20.0% to
$1.2 million in 1998 from $1.0 million in 1997. This increase was due to an
increase in our marketing efforts.

OPERATING INCOME. Operating income increased 90.6% to $6.9 million in 1998
from $3.6 million in 1997. This increase was due primarily to increased revenues
and decreased costs as a percent of revenues.

- ------------------------
(a) Gross profit represents revenues less direct costs, which consist primarily
of project personnel salaries and benefits and direct expenses incurred to
complete projects.

Our revenues and operating results may be subject to significant variation
from quarter to quarter depending on a number of factors, including the progress
of contracts, revenues earned on contracts, the number of billable days in a
quarter, the timing of the pass-through of other direct costs, the commencement
and completion of contracts during any particular quarter, the schedule of the
government agencies for awarding contracts, the term of each contract that we
have been awarded and general economic conditions. For example, revenues in the
first quarter of 1999 were lower than the fourth quarter of 1998 due to two
fewer billable days in the first quarter, and the inclusion in the fourth
quarter's revenues of a larger than usual amount of other direct costs to be
passed through to clients. Because a significant portion of our expenses, such
as personnel and facilities costs, are fixed in the short term, successful
contract performance and variation in the volume of activity as well as in the
number of contracts commenced or completed during any quarter may cause
significant variations in operating results from quarter to quarter.

The federal government's fiscal year ends September 30. If a budget for the
next fiscal year has not been approved by that date, our clients may have to
suspend engagements that we are working on until a budget has been approved.
Such suspensions may cause us to realize lower revenues in the

20
<PAGE>
fourth quarter of the year. Further, a change in Presidential administrations
and in senior government officials may negatively affect the rate at which the
federal government purchases technology.

As a result of the factors above, period to period comparisons of our
revenues and operating results may not be meaningful. You should not rely on
these comparisons as indicators of future performance as no assurances can be
given that quarterly results will not fluctuate, causing a material adverse
effect on our operating results and financial condition.

LIQUIDITY AND CAPITAL RESOURCES

We have funded our operations since inception primarily through cash
generated from operations and the sale of common stock to employees. Net cash
provided by operating activities was $4.5 million for 1999, $2.9 million for
1998 and $3.2 million for 1997. Cash provided by operating activities for these
years was primarily from net income generated during those years.

Net cash used by investing activities was $0.8 million for 1999,
$0.4 million for 1998 and $0.1 million for 1997. During 1999, we purchased $0.8
million of property and equipment. During 1998, we purchased $0.9 million of
property and equipment and sold investments for approximately $0.5 million.
During 1997, we purchased $0.7 million of property and equipment and sold
investments for approximately $0.7 million.

Net cash used in financing activities was $1.0 million for 1999,
$1.7 million for 1998 and $0.3 million for 1997. During 1999, we sold $0.7
million of common stock and repurchased $1.3 million of common stock, while
paying $0.3 million in dividends. During 1998, we sold $0.3 million of common
stock and repurchased $1.7 million of common stock, while paying $0.3 million in
dividends. During 1997, we sold $0.2 million of common stock and repurchased
$0.2 million of common stock, while paying $0.3 million in dividends.

Although dividends have been paid in prior years, after the offering, we
expect to retain future earnings, if any, for use in the operation and expansion
of our business and do not anticipate paying any further cash dividends in the
foreseeable future. Under the terms of our stock option agreement and plan, we
have purchased shares of stock from employees upon their termination of
employment. We intend to terminate these terms and will no longer acquire shares
from terminating employees following the offering.

We believe that our current cash position is adequate for our short-term
working capital and capital expenditure needs. We believe that subsequent to
this offering, our cash position will be adequate for our anticipated long-term
working capital and capital expenditure needs.

We maintain a line of credit with Bank of America, which bears interest at
the bank's prime rate and expires on April 30, 2001. We expect to renew our line
of credit when it expires. As of February 29, 2000, we had no borrowings
outstanding under the line of credit. We did have outstanding $1.25 million in
letters of credit in lieu of rent deposits.

Under some of our fixed-price contracts, we receive advance payments for
work to be performed in future months. If we do not perform the work, the
unearned portion of these advances will be returned to our clients. By the
fourth quarter of 1999, our accounts receivable turn over rate, net of advance
payments on contracts, was approximately five times a year. This rate has
improved over the last eight quarters, thus increasing our cash flow. At this
collection rate management believes cash generated through operations will be
sufficient to fund short and long-term cash needs.

YEAR 2000 COMPLIANCE

Although we have not experienced any significant failures or problems in
connection with the Year 2000 date change in either our software or the systems
we have developed for our clients, our clients

21
<PAGE>
may still experience significant problems that may require them to divert
significant resources to remediation instead of to new eGovernment solutions.
This could delay our ability to generate new business and additional revenues.

Furthermore, undiscovered Year 2000 problems may also affect software or
code that we develop or third-party software products that are incorporated into
the information systems solutions we create for our clients. Our clients license
software directly from third parties, and we do not guarantee that the software
licensed from these suppliers is Year 2000 compliant. However, if we fail to
provide our clients Year 2000 compliant information systems solutions we could
suffer financial loss, harm to our reputation and liability to others and could
seriously harm our business, financial condition and operating results.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS 133, as
amended, is effective for quarters beginning after June 15, 2000. Currently, we
do not use derivative financial instruments. As a result, we do not expect
SFAS 133 to have a material impact on our results of operations or financial
position.

BUSINESS

OVERVIEW

Our clients have included every cabinet-level department of the federal
government as well as numerous additional entities at the federal, state and
local levels. This group includes a cross-section of civil, law enforcement,
intelligence and judicial government organizations. Our largest clients include
the Drug Enforcement Administration, the Immigration and Naturalization Service,
the Veterans Benefits Administration, the Internal Revenue Service, the Bureau
of Alcohol, Tobacco and Firearms and the intelligence community. Since 1995, we
have provided more than $145 million of services in the government market and
have increased revenues at approximately a 48% compound annual growth rate.

INDUSTRY BACKGROUND

The emergence and adoption of the Internet as a means of gathering,
communicating and managing information continues to open up new possibilities
for businesses and organizations to dramatically improve productivity and
effectiveness. Government has emerged in recent years as one of the leading
purchasers of Internet and other advanced technology solutions. With respect to
technology services, International Data Corporation estimates that government
spending will increase from $11.8 billion in 1997 to $17.3 billion in 2002.
Government spending on Internet professional technology services alone is
expected to grow at approximately a 56% compound annual growth rate, reaching
$2.8 billion in 2003.

GOVERNMENT REFORM IS DRIVING GROWTH IN ADVANCED TECHNOLOGY SPENDING

We believe that political pressures and budgetary constraints are forcing
government agencies at all levels to improve their processes and services and to
operate more like commercial enterprises. Organizations throughout the federal,
state and local governments are investing heavily in information technology to
improve effectiveness, enhance productivity and extend new services in order to
deliver increasingly responsive and cost-effective public services. We believe
that Internet technologies provide an ideal solution to meet government's needs.

Recent changes in federal government contract procurement and compliance
regulations have streamlined the government's buying practices, resulting in a
more commercial approach to the procurement and management of technologies and
services. As a result, procurement lead times have decreased and government
buyers now have greater flexibility to purchase services on the basis of
distinguishing corporate capabilities and successful past performance. Federal
government entities now are able to award contracts based on factors other than
price alone, if they judge that the government would receive a greater value. In
addition, the General Services Administration's extension of basic
government-wide contract vehicles for procuring technology components and
services, the GSA Schedules, makes purchasing technology services easier and
faster. Federal government buyers can now order services directly from
pre-approved providers instead of using a time-consuming bid solicitation
process. We believe that these changes have improved our ability to successfully
pursue business in the government market. There are currently no proposed
changes to government procurement regulations that we believe will materially
affect our business in the immediate future.

23
<PAGE>
GOVERNMENT'S NEED TO OUTSOURCE TECHNOLOGY PROGRAMS

Government organizations rely heavily on outside contractors to provide
skilled resources to accomplish technology programs. In 1999 alone, according to
Electronics Industry Association estimates, the federal government outsourced
$26 billion of its $30 billion information technology budget. We believe that
this reliance will continue to intensify due to political and budgetary
pressures in many government agencies and due to the difficulties government
faces in recruiting and retaining highly skilled technology professionals in a
competitive labor market. In concert with its transition to more commercial
practices, government is increasingly outsourcing technology programs as a means
of simplifying the implementation and management of the technology, so that
government workers can focus on their mission.

TECHNOLOGY SERVICES PROVIDERS IN THE GOVERNMENT SECTOR

Engagements in the government market can be broadly classified into four
categories based on the type of services provided. Many companies provide a mix
of services across these categories.

First, at the low end, providing information technology staff augmentation
at low hourly rates typically involves placing staff in client facilities. These
engagements typically exhibit low operating margins and slow growth.

Second, large-scale systems integration and outsourcing engagements
typically involve assuming responsibility for acquiring, assembling and
operating large inventories of equipment and software. Major portions of these
engagements involve reselling commodity technologies at highly competitive fixed
unit prices. These engagements typically exhibit moderate growth, but low
operating margins.

Third, large-scale systems development engagements involve providing
full-service solutions that combine hardware, software development, system
engineering and operations. These engagements typically exhibit moderate growth
and operating margins.

Fourth, at the high end, engagements involving high-value management
consulting and development and integration of complex systems in core mission
areas use specialized or emerging technologies such as the Internet and advanced
security. These engagements typically exhibit strong growth and operating
margins.

CHALLENGES IN THE GOVERNMENT TECHNOLOGY SERVICES SECTOR

Technology services providers face a unique combination of challenges when
providing services to the government. These include:

- substantial government investments in legacy systems that are not readily
adaptable to evolving technologies;

- extremely large volumes of data collected and retained in government
databases;

- large and widely dispersed workforces, often consisting of tens of
thousands of knowledge workers located in hundreds of sites throughout the
United States and the world;

- heightened security concerns due to the need to protect individual privacy
and extraordinarily sensitive information; and

- complex management needs that require a combination of strategic planning
capabilities, government domain expertise, public sector procurement savvy
and cutting-edge technology skills.

<PAGE>
OUR STRATEGY

Our strategy is to continue to grow by capitalizing on our leadership
position in the eGovernment solutions market. Our strategies for obtaining this
objective include:

MAINTAINING OUR TECHNOLOGY LEADERSHIP POSITION

We will continue to focus on high-end engagements that require specialized
knowledge of emerging technologies. We intend to maintain our technology
leadership by recruiting employees who will add to our inventory of technology
skills and by refining the skills and capabilities of our existing staff through
training, certification and hands-on laboratory experimentation. We also intend
to work closely with our technology partners to share expertise and innovations
and to stay well ahead of competitors in the practical aspects of applying and
integrating emerging technologies.

INCREASING FEDERAL GOVERNMENT MARKET PENETRATION

We intend to capitalize on our long-term relationships with government
clients and our reputation within the government market to cross-sell our full
range of services to our existing client base and to expand into organizations
in the federal government for which we have not already performed services. We
intend to pursue these opportunities through a continued active sales and
marketing effort and by continuing to promote the success stories stemming from
our aggressive application of eGovernment solutions. We also intend to leverage
our relationships with our technology providers and their sales resources to
obtain new federal government clients.

ENHANCING THE PEC SOLUTIONS BRAND AND CULTURE

We are implementing an aggressive program to build the identity and
awareness of the PEC Solutions brand in order to improve our visibility in the
marketplace and to attract the best and brightest employees. We intend to hire
and retain outstanding professionals, provide incentives to achieve corporate
goals and maintain a culture that fosters innovation. We will continue to
emphasize professional development and training of our employees. We will
maintain an active internal communications program to promote a team culture and
foster high employee morale. We will also continue to emphasize our corporate
technology infrastructure to facilitate the sharing of knowledge among our
employees.

EXPANDING OUR PRESENCE IN STATE AND LOCAL GOVERNMENT AND SELECTED COMMERCIAL
MARKETS

We intend to leverage our domain expertise and deep technology skills for
providing services to state and local governments. We also intend to expand our
business of web-enabling private sector organizations that operate in highly
regulated industries and that have significant interactions with the government
agencies with which we work. We believe our existing solution sets, such as case
management systems, criminal suspect booking stations, and land and financial
records automation, are applicable to projects at the state and local level, as
well as at private sector organizations.

UNDERTAKING A DISCIPLINED ACQUISITION PROGRAM

We plan to broaden our capabilities and client base and extend our
geographic presence in state and local government markets by acquiring select
businesses. Acquired businesses will perform similar technical work for
organizations outside our current client base, will support solution sets that
are consistent with and extend our web-enabling strategy, or will be located in
geographic areas strategic to significant state and local governments and
programs.

<PAGE>
OUR SERVICES

As a provider of eGovernment solutions, we offer a variety of services
across the full technology lifecycle. These services include:

STRATEGY AND DESIGN

We help clients develop the operational vision for integrated mission
solutions, and formulate the business and execution plans for realizing
imaginative, integrated and aggressive technology solutions. We develop
sophisticated enterprise architectures--the technology blueprints and systematic
guidance that allow enterprises to incrementally develop, migrate to and operate
large-scale systems. By re-engineering government processes, we move
organizations to an eGovernment environment. We perform economic analyses to
weigh the costs of technology investment against the operational benefits
expected from such technology implementation. We provide support to
organizations that are executing programs to privatize large-scale information
systems operations, or are undertaking far-reaching changes in their business
models, such as migrating from appropriated to fee-for-service financial models.

SOLUTIONS DEVELOPMENT AND IMPLEMENTATION

We develop, engineer and integrate computer hardware, commercial software,
reusable solution sets, custom-built applications and networks to create
integrated business solutions for our clients. Our emphasis on Internet
technology allows us to combine leading-edge technologies with disciplined and
effective system development methodologies. Our methods are designed to ensure
that the technology fits with business processes and that users realize process
improvement. We distinguish ourselves by addressing the core technical and
business challenges in migrating large government enterprises to integrated
eGovernment solutions. We build:

- INTEGRATED MISSION APPLICATIONS. We integrate complex back-office
business applications and legacy systems with customized mission
applications using the information-sharing capabilities of open
architectures. We also design, develop and install complex custom
application systems that implement knowledge management repositories and
tera-byte data warehousing systems allowing government agencies to mine
the vast storehouses of records that they collect and maintain.

- LARGE-SCALE INTRANET INFRASTRUCTURES. We deploy and manage complex
international network infrastructures: intranets and extranets that
deliver the performance, reliability and flexibility needed to support the
diverse needs of web-enabled organizations with thousands of widely-
dispersed knowledge workers.

- LEADING-EDGE AUTHENTICATION AND ENCRYPTION SECURITY APPLICATIONS. We
apply advanced security technologies such as: public key infrastructure to
manage data encryption systems; biometric authentication to identify
individuals by their physical characteristics; and strong encryption to
protect sensitive information in highly decentralized systems against
unauthorized access and compromised integrity.

- AUTOMATED ENTERPRISE MANAGEMENT SYSTEMS. We develop and deploy processes
and automated tools for our clients to centrally manage and operate
complex national networks of workstations and servers at reduced cost.

ONGOING SYSTEMS MANAGEMENT AND ENHANCEMENT

We provide long-term, ongoing support for our solutions including the
operation, management and enhancement actions necessary to keep solutions
up-to-date with evolving business processes and technologies. We use
sophisticated tools to reduce the burden and costs of maintaining large complex
intranets, and to enhance whole systems without the need to deploy engineers and
field service technicians to the operating locations of an enterprise. We
operate highly automated enterprise technology management processes that support
integration, configuration management, software distribution and user support,
and allow clients to outsource the responsibilities for maintaining their

27
<PAGE>
technology infrastructures and applications. The results are reduced operating
costs for our clients and improved performance and reliability.

OUR CLIENTS

We generated significant revenue from each of the following departments or
agencies, either directly or through subcontracting relationships, in 1999:

<TABLE>
<S> <C>
Bureau of Alcohol, Tobacco & Firearms Drug Enforcement Administration (DEA)
Census Bureau Fairfax County, Virginia
Defense Medical Service Federal Judiciary
Department of Agriculture Health Care Financing Administration
Department of Interior Immigration & Naturalization Service
Department of Transportation Internal Revenue Service
Department of Veterans Affairs Justice Management Division
</TABLE>

We consider each office or division within an agency or department which
directly, or through a prime contractor, engages us as a separate client.
Although contained within a larger organization, each of these clients has
decision-making and contracting authority independent of the larger organization
and its other offices or divisions.

In 1999, our top five clients represented approximately 40% of our revenues
and our top ten clients represented approximately 60% of revenues. Our work for
the DEA Special Projects Division accounted for 14.2% of our revenues during
1999.

In 1999, we derived approximately 40% of our revenues through relationships
with prime contractors, who contract directly with the end-client and
subcontract with us. In most of these engagements, we retain full responsibility
for the end-client relationship with respect to the portions of the engagement
subcontracted to us and direct and manage the activities of our staff. Of our
prime contractors, only Unisys accounted for more than 10% of our revenues
during 1999.

In 1998, our work for the DEA Special Projects Division accounted for 16.5%
of our revenues. In 1997, our work for the DEA Special Projects Division
accounted for 11.2% of our revenues and our work for the Internal Revenue
Service accounted for 10.2% of our revenues.

REPRESENTATIVE CLIENT SOLUTIONS

The following are representative case studies of our eGovernment solutions:

<TABLE>
<S> <C>
A MAJOR FEDERAL LAW ENFORCEMENT AGENCY

Challenge: Securely collect and provide access to investigative
information for law enforcement agents worldwide.

Solution: Design, implement, support and continually enhance an
encrypted, international law enforcement intranet that
stores and protects digital intelligence files for
government agents.

Features and Benefits: This intranet provides integrated administrative,
intelligence and case management applications for more than
11,000 agents and administrative staff around the world. Law
enforcement agents, using intranet services, spend less time
on administrative chores and have more time for
investigative and "on-the-street" activities. Preliminary
studies show a 31-day reduction in the time taken to
formally register an investigative report. We have
incorporated technology into this intranet well beyond that
employed on the public Internet. For example, by using
advanced enterprise management tools, our engineers in
Virginia install and troubleshoot software on personal
computers as far away as California. Using this technology,
we monitor and manage over 230 intranet servers and 7,800
personal computers at over 150 sites with a small team of
engineers in our Virginia offices. In addition, we have
integrated hardware encryption, public key encryption and
digital signature technologies to safeguard critical
investigative information on this intranet.

INTERNAL REVENUE SERVICE ("IRS")

Challenge: Enforce complex tax laws and identify tax return fraud.

Solution: Design, implement, and support a large-scale electronic
fraud detection system to automatically identify patterns of
illegal taxpayer behavior over multiple years.

Features and Benefits: Manual review can detect only a small percentage of
fraudulent returns. The IRS asked us to build what has
become one of the most successful processing systems of the
Tax System Modernization program. The Electronic Fraud
Detection System (EFDS) uses decision support software that
we developed in conjunction with Los Alamos National
Laboratories to process and review every electronic return
(approaching 32 million returns annually) and an increasing
number of manually-filed returns each year. EFDS supports
over 700 tax examiners nationwide. With three full years of
tax return data, comprising over 3.5 terabytes online, EFDS
is among the largest Oracle database systems. The EFDS is an
important part of the IRS plan to achieve the
Congressionally-mandated goal of processing 80% of tax
returns electronically by 2007.
</TABLE>

29
<PAGE>
<TABLE>
<S> <C>
IMMIGRATION AND NATURALIZATION SERVICE ("INS")

Challenge: Provide INS case examiners with an integrated picture of the
refugee, naturalization, criminal and asylum history for
immigrants and aliens, based on information stored in
independent legacy databases.

Solution: Design and build a system that connects an integrated web
browser front end to five legacy INS databases and presents
a complete immigrant/alien profile.

Features and Benefits: We designed and implemented a web-based system that queries
multiple INS mainframe databases and automatically provides
consolidated reports to the INS. INS caseworkers will use
their desktop browsers to connect to a web server that we
developed. Based on requests from the user, the server
automatically queries five different INS databases with
records on over 45 million immigrants and aliens.
Accordingly, INS caseworkers will get a more complete
picture of an immigrant's or alien's history and can gather
data and generate reports much more quickly. Our preliminary
tests indicate that this new system will reduce the time to
respond to a query by over 80%. The INS can realize savings
in user training and employee productivity without having to
abandon its large investment in legacy databases.

BUREAU OF ALCOHOL, TOBACCO AND FIREARMS ("ATF")

Challenge: Provide ATF agents and law enforcement officials across the
country with rapid access to a large repository of
information regarding firearms, arson and explosives, and
other valuable criminal investigative case records,
previously contained in paper files.

Solution: Design, develop, deploy and continue to enhance an
integrated case information and management system that
enables agents to access ATF data stores within the bureau
and enables the ATF to publish crime statistics on the web.

Features and Benefits: ATF agents access and generate large amounts of valuable
intelligence information on firearms, arson, and explosives
in the process of conducting investigations. Prior to our
involvement, many ATF records were paper-based. ATF's
largely manual systems made it difficult and time consuming
to collect, record and correlate data while investigating a
crime. We designed and implemented an integrated knowledge
management system that provides access to seven different
case data repositories under a common framework. By using
our system, ATF agents need to enter case information only
once. The system categorizes the investigative information
and makes it accessible to 2,000 users in over 193 ATF
offices across the nation. Crime statistics derived from
this data are available to the public and local law
enforcement organizations through the ATF web site.

THE CIRCUIT COURT OF FAIRFAX COUNTY, VIRGINIA

Challenge: Preserve and improve public access to over two centuries of
land and legal records for one of the largest local
governments (by revenue) in the United States.

Solution: Design and implement an e-commerce solution using a
web-enabled repository of county public records and
documents.

Features and Benefits: Fairfax County needed a way to preserve aging land records
dating back to 1742, to manage the rapidly increasing volume
of documents and to improve service to the County's
residents and businesses. The web-based land record system
that we designed puts the County's archive--over 14 million
images including deeds, plats, wills and financial
documents--on the Internet. The system has the capacity to
support 20,000 image retrievals per hour. Rather than
waiting in long lines, customers can access these public
documents electronically at a public retrieval station in
the County courthouse. Real estate attorneys and other
businesses that wish to gain access from their offices over
the Internet can do so by paying a subscription fee to the
County.

DRUG ENFORCEMENT ADMINISTRATION ("DEA"), OFFICE OF DIVERSION CONTROL

Challenge: Ensure that the rapid industry movement toward electronic
prescription processing does not result in an increase in
the amount of drugs diverted from legitimate use to the
black market.

Solution: Develop a strategy that employs encryption and digital
signature technology to safeguard prescription fulfillment
and develop a regulatory reporting process that integrates
with the business-to-business transactions between
pharmacies, distributors and drug manufacturers.

Features and Benefits: Three business interfaces are involved in the prescription
fulfillment process: physician-to-pharmacy,
pharmacy-to-distributor and distributor-to-manufacturer. The
pharmacies, distributors and manufacturers already use
electronic data interchange (EDI) technology to process drug
orders. The DEA has hired us to design processes that
integrate with the industry's electronic processes and guard
against diversion but that do not impede the efficiencies
gained by e-commerce. In contrast, physicians are only
beginning to send electronic prescriptions to pharmacies. In
this case, we will design processes using Internet security
technologies that increase the efficiency of prescription
fulfillment, prevent diversion and reduce the chance of
medical error. The DEA is using our skills and experience
with security technologies, including public key
infrastructure and digital signature, to help in this
effort. The conceptual design for this program must
accommodate one million physicians, pharmacies, drug
manufacturers and distributors. The Department of Veterans
Affairs (VA), which employs 4,000 pharmacists nationwide who
fill 68 million prescriptions a year, will conduct the pilot
program. We will work with the VA, our long-time client, to
test the automation and digital protection of prescription
flow and diversion prevention.

SALES AND MARKETING

Our marketing efforts are focused on creating awareness of opportunities in
eGovernment innovation, establishing PEC Solutions as a leader in this new
category and building the PEC brand.

We market and sell our services through multiple channels by using our
business development staff, leveraging existing client relationships,
capitalizing on our task order contracts, responding to competitive
solicitations, attending marketing events and engaging in other public relations
activities. We employ marketing research services to identify and track
potential contract opportunities. We also cultivate relationships with
leading-edge technology vendors, such as Entrust Technologies and IBM, and prime
contractors, such as Unisys, to identify and obtain project leads consistent
with our capabilities.

We employ a team selling approach, whereby our business developers
collaborate with our service delivery professionals and management to identify
prospects, conduct sales and manage client relationships. Our Vice President of
Strategic Programs coordinates the activities of our business development staff.
We allocate business developers to each of our business units who pursue new
clients and programs across their market segments. Each current client is
assigned to a relationship manager who is responsible for ensuring client
satisfaction and successful project performance, and identifying new business
opportunities with the client.

CULTURE, PEOPLE AND RECRUITING

We have developed a corporate culture that promotes excellence in job
performance, respect for the ideas and judgment of our colleagues and
recognition of the value of the unique skills and capabilities of our
professional staff. We seek to attract highly qualified and ambitious staff. We
strive to establish an environment in which all employees can make their best
personal contribution and have the satisfaction of being part of a unique team.
We believe that we have successfully attracted and retained highly skilled
employees because of the quality of our work environment, the professional
challenge of our assignments, and the financial and career advancement
opportunities we make available to our staff.

We occupy state-of-the art facilities that are conducive to highly technical
and collaborative work, while providing individual privacy. In our solutions
centers, we configure large networks of leading-edge equipment and software, and
provide our engineers and developers with advanced tools to evaluate and apply
new technologies. We believe that the location, environment and amenities
provided by our new Fair Lakes campus facility will contribute to our ability to
attract and retain highly skilled employees.

As of December 31, 1999, we had 429 employees. Of our employees, 382 were
consulting and service delivery professionals, and 47 were management and
administrative personnel performing corporate marketing, human resources,
finance, accounting, legal, internal information systems and administrative
functions. None of our employees is represented by a collective bargaining unit.

In addition to standard company benefits, we provide:

- tuition reimbursement for employees pursuing advanced academic degrees;

- professional training programs;

- financial incentives for employees obtaining product competency
certifications;

- a bonus program;

- spot cash awards to reward specific employee accomplishments; and

- stock option grants based on job performance.

We invest heavily in technical staff recruiting resources and hiring
programs. Each of our business units is staffed with a dedicated recruiter, and
we aggressively use a variety of recruiting methods, including advertising, job
fairs, open houses and Internet-based career placement services. We also offer
substantial awards and recognition to our current employees for referrals, which
has been particularly effective in identifying and recruiting talented staff.

32
<PAGE>
We have developed an active and effective college recruiting program that
draws on management staff and recent college hires from across the company to
attract graduating students with strong academic backgrounds in our core
disciplines. We currently target colleges and universities in Washington, D.C.,
Maryland, and Virginia with this program, and perform on-campus recruiting
during the spring and fall recruiting seasons at five universities.

COMPETITION

Our current competitors include, and may in the future include, the
following:

- information technology services providers and large government contractors
such as American Management Systems, Andersen Consulting, Booz, Allen &
Hamilton, Computer Sciences Corporation, Electronic Data Systems, KPMG,
PricewaterhouseCoopers, Science Applications International Corporation and
Unisys; and

- Internet professional services providers.

Many of our competitors have long operating histories and strong client
relationships, greater financial, technical, marketing and public relations
resources, larger client bases and greater brand or name recognition than we
have.

We believe that the major competitive factors in our market relate to a
company's distinctive technical capabilities, successful past contract
performance, reputation for quality and key management and marketing staff.
Under best-value procurement methods, price is an important, but secondary,
factor in the selection of a technology service provider.

INTELLECTUAL PROPERTY RIGHTS

Our success is dependent, in part, upon our proprietary processes,
components and other intellectual property rights. We do not have any patents or
patent applications pending. We rely on a combination of trade secret,
nondisclosure and other contractual agreements, and copyright and trademark
laws, to protect our proprietary rights. Existing trade secret and copyright
laws afford us only limited protection. We enter into confidentiality agreements
with our employees and our contractors and limit access to and distribution of
our proprietary information. There can be no assurance that the steps we have
taken in this regard will be adequate to deter misappropriation of our
proprietary information or that we will be able to detect unauthorized use and
take appropriate steps to enforce our intellectual property rights.

A portion of our business involves the development of software applications
for specific client engagements. Although ownership of client-specific software
is generally retained by the client, we retain some rights to the applications,
processes and intellectual property developed in connection with client
engagements.

FACILITIES

In January 2000, we moved our headquarters to a new 96,000 square foot
building in Fairfax, Virginia. We have a 14-year lease on this new facility with
two five-year options to extend. This building will be part of a corporate
campus facility being constructed on our behalf.

We have additional operating facilities throughout the metropolitan
Washington, D.C. area and the nation. In addition to our facilities in Fairfax
County, Virginia, we lease operating facilities in Baltimore, Maryland and
Denver, Colorado. We also have employees working at client sites throughout the
United States.

LEGAL PROCEEDINGS

Although we are not involved in any material legal proceedings, from time to
time we become a party to legal proceedings arising in the ordinary course of
business. Any such proceeding, even if the claims are without merit, could
result in us spending significant financial and managerial resources.

OPTIONS GRANTS IN 1999

The following table sets forth information regarding options granted to the
named executive officers.

We recommend caution in interpreting the financial significance of the
figures representing the potential realizable value of the stock options. They
are calculated by multiplying the number of shares underlying the options
granted by the difference between a future hypothetical stock price and the
option exercise price and are shown pursuant to rules of the SEC. They assume
the market price of common stock appreciates 5% or 10% each year, compounded
annually, for the applicable term of the option. They are not intended to
forecast possible future appreciation, if any, of our stock price or to
establish a present value of options. Also, if appreciation does occur at the 5%
or 10% per year rate, the amounts shown would not be realized by the recipients
until the year 2003 or 2008. Depending on inflation rates, these amounts may be
worth significantly less in those years, in real terms, than their value today.

for Mr. Lloyd; multiplied by the number of shares acquired.

NONQUALIFIED EXECUTIVE SUPPLEMENTAL RETIREMENT PLAN

In December 1998, we entered into a nonqualified executive supplemental
retirement program agreement with each of the named executive officers. Under
this plan, each named executive officer may defer a percentage of his salary
each year, which, with the amount he defers under our 401(k) plan, may not
exceed 15%. In addition, each executive officer may elect to defer any bonuses
awarded to him. Any deferred salary and bonus amounts vest immediately. We also
may make voluntary

38
<PAGE>
contributions to each executive officer's account, which will vest five years
from the date we make the contribution. We will invest or use deferred amounts
as we deem appropriate.

Upon reaching the age of 65, the executive officer may elect to receive the
deferred amount as adjusted for investment gains and losses. Each executive
officer also may elect to begin receiving payment from his deferred account upon
reaching the age of 55, if he retires from our company and agrees not to compete
against us for a period of five years. Deferred amounts will be paid in three
equal annual payments.

EMPLOYMENT ARRANGEMENTS

We have entered into employment agreements with Dr. Karlgaard and
Messrs. Rice and Harbitter. The agreements have initial terms of two years and
are automatically extended for additional one year terms. If Dr. Karlgaard,
Mr. Rice or Mr. Harbitter is terminated for any reason other than for cause or
terminates his agreement for good reason, the employment agreements provide that
he is entitled to receive severance payments over a period equal to the greater
of the remaining term of his agreement or one year. The employment agreements
restrict Dr. Karlgaard and Messrs. Rice and Harbitter from competing with us for
a period of two years following termination of employment.

On December 31, 1998, we entered into an employment agreement with Stuart
Lloyd. The agreement has an initial term of five years and is automatically
extended for additional one year terms unless we, by providing one year's
notice, elect not to renew the agreement. Mr. Lloyd, by providing 90 days
notice, can terminate the agreement before the end of the current term. Under
this agreement, Mr. Lloyd receives an initial annual base salary that will be
increased at specified rates through 2001 and will be subject to adjustment by
our board of directors and our compensation committee thereafter. He also may
receive an annual cash bonus of up to 20% of his then current salary under our
fall bonus plan, based upon performance objectives set by our senior management,
and another cash bonus under our spring bonus plan not to exceed our net income
margin as a percentage of his base salary. Mr. Lloyd, along with the other named
executive officers, also receives beneficial use of an automobile.

Upon signing his employment agreement, Mr. Lloyd was granted options to
purchase 60,000 shares of common stock at $2.04 per share. In the event that
Mr. Lloyd determines to exercise any of these options through the use of
proceeds borrowed from a third party lender, we have agreed that we will
guarantee the loan on the condition that we receive a collateral security
interest in the common stock acquired upon exercise. If, during the term of his
employment agreement, we terminate Mr. Lloyd's employment without cause, he will
be entitled to, in one lump sum, the base salary, bonus, all employee benefits
and stock options he would have received over the remainder of the term of the
agreement. In addition, if we terminate Mr. Lloyd's employment without good
reason following a change of control, he will be entitled to the compensation he
would have received had the agreement been fully performed. Mr. Lloyd has agreed
to a non-competition provision that will be in effect during the term of his
agreement and for two years after the agreement is terminated unless terminated
as a result of a breach by us of one of the agreement's provisions.

Each named executive officer has agreed to preserve the confidentiality and
the proprietary nature of all information relating to our business during and
after the term of his employment.

STOCK OPTION AGREEMENT AND NONQUALIFIED STOCK OPTION PLAN

We adopted our stock option agreement in February 1987 and our nonqualified
stock option plan in January 1995. The 1987 stock option agreement provides for
the grant of stock options to our employees, including executive officers, that
are intended to qualify as incentive stock options within the meaning of
Section 422 of the Internal Revenue Code. The 1995 nonqualified stock option
plan provides for the grant of stock options to employees and directors that are
not intended to qualify as incentive stock options. The exercisability of
options granted under the 1987 stock option agreement

39
<PAGE>
may in certain circumstances be accelerated in connection with an acquisition
event, as defined in the agreement.

As of December 31, 1999, we had outstanding options to purchase an aggregate
of 5,668,890 shares of common stock under the 1987 stock option agreement and
the 1995 nonqualified stock option plan. Options granted under the 1987 stock
option agreement generally vest two years from the date of grant. Options
granted under the 1995 nonqualified stock option plan vest immediately. No
further options will be granted under the 1987 stock option agreement or the
1995 nonqualified stock option plan. Options granted under the 1987 stock option
agreement or the 1995 nonqualified stock option plan will remain outstanding
according to their terms.

2000 STOCK INCENTIVE PLAN

We adopted our 2000 stock incentive plan in January 2000. This plan
authorizes the grant of:

- stock options;

- stock appreciation rights;

- stock awards;

- phantom stock;

- performance awards; and

- other stock-based awards.

The compensation committee of our board of directors administers our 2000
stock incentive plan. The committee has sole power and authority, consistent
with the provisions of this plan, to determine which eligible participants will
receive awards, the form of the awards and the number of shares of our common
stock covered by each award. The committee may impose terms, limits,
restrictions and conditions upon awards, and may modify, amend, extend or renew
awards, to accelerate or change the exercise timing of awards or to waive any
restrictions or conditions to an award.

The number of shares of common stock available for issuance under our 2000
stock incentive plan during 2000 is 1,500,000. Beginning in 2001, the number of
shares eligible for grant in each year will be equal to the sum of (i) 6.25% of
the number of outstanding shares on January 1 of that year plus (ii) the number
of shares eligible for grant in the prior year that were not granted. No more
than 15,000,000 shares may be issued pursuant to incentive stock options during
the 10-year term of the plan. At March 1, 2000, we granted options to purchase
212,193 shares of common stock at an exercise price of $12.00 per share under
this plan.

STOCK OPTIONS. Our 2000 stock incentive plan permits the granting of
options to purchase shares of our common stock intended to qualify as incentive
stock options under the Internal Revenue Code and stock options that do not
qualify as incentive options. The option exercise price of each option will be
determined by the committee. The term of each option will be fixed by the
committee. The committee will determine at what time or times each option may be
exercised and, the period of time, if any, after retirement, death, disability
or termination of employment during which options may be exercised.

STOCK APPRECIATION RIGHTS. The committee may grant a right to receive a
number of shares or, in the discretion of the committee, an amount in cash or a
combination of shares and cash, based on the increase in the fair market value
of the shares underlying the right during a stated period specified by the
committee.

STOCK AWARDS. The committee may award shares of our common stock, cash, or
a combination of shares of common stock and cash, to participants at no cost or
for a purchase price. These stock awards may be subject to restrictions or may
be free from any restrictions under our 2000 stock incentive plan. The committee
shall determine the applicable restrictions. The purchase price of the shares of
our common stock will be determined by the committee.

40
<PAGE>
PHANTOM STOCK. The committee may grant stock equivalent rights, or phantom
stock, which entitle the recipient to receive credits which are ultimately
payable in the form of cash, shares of our common stock or a combination of
both. Phantom stock does not entitle the holder to any rights as a stockholder.

PERFORMANCE AWARDS. The committee may grant performance awards to
participants entitling the participants to receive cash, shares of our common
stock, or a combination of both, upon the achievement of performance goals and
other conditions determined by the committee. The performance goals may be based
on our operating income, or on one or more other business criteria selected by
the committee.

OTHER STOCK-BASED AWARDS. The committee may grant other stock-based awards.
These stock-based awards may be denominated in cash, in common stock, or other
securities, in stock-equivalent units, in stock appreciation units, in
securities or debentures convertible into common stock, or in any combination of
the foregoing and may be paid in common stock or other securities, in cash, or
in a combination of common stock or other securities and cash, all as determined
in the sole discretion of the committee.

2000 EMPLOYEE STOCK PURCHASE PLAN

Our employee stock purchase plan, which we adopted in January 2000, provides
for the issuance of up to 2,000,000 shares of common stock. This plan, which is
intended to qualify under Section 423 of the Internal Revenue Code, provides our
employees with an opportunity to purchase shares of our common stock through
payroll deductions.

All of our employees, including directors who are employees, are eligible to
participate in the purchase plan. Options to purchase our common stock will
initially be granted to each eligible employee on the first trading day on or
after the date of this offering. Thereafter, options will be granted on the
first trading day after January 1 of each year, or such other date as determined
by the administrator. Each option will terminate on the last trading day of a
period specified by the administrator and no option period will be longer than
27 months in duration. Subsequent option periods of equal duration will
consecutively follow, unless the administrator determines otherwise.

Each option represents a right to purchase shares of our common stock. The
administrator determines the purchase price of each share of common stock,
provided that the purchase price will never be less than the lesser of 85% of
the fair market value of the common stock on the first trading day of the option
period or the date the shares of common stock are purchased.

Any employee who immediately after a grant owns 5% or more of the total
combined voting power or value of our capital stock may not be granted an option
to purchase common stock under the purchase plan. Participation may also be
limited where rights to purchase stock under all other purchase plans accrue at
a rate which exceeds $25,000 of the fair market value of our common stock for
each calendar year.

401(K) PLAN

We maintain a retirement savings and investment plan, or 401(k) plan,
covering all employees. The 401(k) plan is intended to qualify under
Section 401(k) of the Internal Revenue Code of 1986, as amended, so that
contributions to the 401(k) plan by employees, and the investment earnings
thereon, are not taxable to employees until withdrawn from the 401(k) plan.
Under the 401(k) plan, employees may elect to reduce their current compensation
by up to the lesser of 15% of their annual compensation or the statutorily
prescribed annual limit ($10,500 in 2000) and to have the amount of the
reduction contributed to the 401(k) plan. We may make additional matching or
discretionary contributions, or both, to the 401(k) plan for the benefit of
participants in the plan. The participant's contribution is 100% vested
immediately upon contribution. Contributions made by us into the participant's
account vest 20% every year over a five year period beginning two years from the
initial date of employment with us.

the board of directors.

GUARANTY OF LOANS

Under the terms of Mr. Lloyd's employment agreement, we may be required to
guarantee loans made to Mr. Lloyd by third party lenders, the proceeds of which

Arrangements."

PRINCIPAL AND SELLING STOCKHOLDERS

The following table sets certain information regarding beneficial ownership
of our common stock as of March 1, 2000 and as adjusted to reflect the sale of
the shares offered hereby, by:

- each person who we know beneficially owns more that 5% of our common
stock;

- each member of our board of directors;

- each of our named executive officers; and

- all directors and executive officers as a group.

The term "beneficial ownership" includes shares over which the indicated
beneficial owner exercises voting and/or investment power. The rules also deem
common stock subject to options currently exercisable, or exercisable within
60 days, to be outstanding for purposes of computing the percentage ownership of
the person holding the options, but they do not deem such stock to be
outstanding for purposes of computing the percentage ownership of any other
person. The applicable percentage ownership before the offering for each
stockholder is based on 18,959,046 shares of common stock outstanding as of
March 1, 2000, together with options for that stockholder exercisable within
60 days of March 1, 2000. For purposes of calculating the percentage
beneficially owned after the offering, the number of shares deemed outstanding
includes: (a) all shares deemed to be outstanding before the offering and
(b) 3,500,000 additional shares being sold in this offering.

The address for each stockholder listed is c/o PEC Solutions, Inc. 12750
Fair Lakes Circle, Fairfax, Virginia 22033. Each of the persons named in this
table has sole voting and investment power with respect to all the shares
indicated. An asterisk indicates ownership of less than 1%.

DESCRIPTION OF OUR CAPITAL STOCK

Our authorized capital stock consists of 75,000,000 shares of common stock,
with a par value of $0.01 per share, and 10,000,000 shares of undesignated
capital stock, with a par value of $0.01 per share. As of March 1, 2000, there
were 18,959,046 shares of our common stock outstanding, held of record by 78
stockholders. After this offering, we will have outstanding 22,459,046 shares of
common stock. No other classes of stock have been designated or issued.

The following is a description of our capital stock.

COMMON STOCK

Holders of common stock are entitled to one vote per share of record on all
matters to be voted upon by the stockholders. Subject to preferences of any
preferred stock that may be issued in the future, the holders of common stock
are entitled to receive any dividends that may be declared by the board of
directors. In the event of a liquidation, dissolution, or winding up of the
affairs of our company, the holders of common stock will be entitled to receive
pro rata all of our remaining assets available for distribution to stockholders.
Any pro rata distribution would be subject to the rights of the holders of any
outstanding shares of preferred stock. Our common stock has no preemptive,
redemption, conversion or subscription rights. Piper Marbury Rudnick & Wolfe
LLP, our counsel, will opine that the shares of common stock to be issued by us
in this offering, when issued and sold in the manner described in the prospectus
and in accordance with the resolutions adopted by the board of directors, will
be fully paid and non-assessable.

UNDESIGNATED CAPITAL STOCK

Our board has authority to designate and issue up to 10,000,000 shares of
capital stock, in one or more series. Our board can establish the preferences,
rights and privileges of each series, which may be superior to the rights of the
common stock.

ANTI-TAKEOVER EFFECTS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND
DELAWARE GENERAL CORPORATION LAW

OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND DELAWARE GENERAL CORPORATION
LAW. Certain provisions of Delaware law and our certificate of incorporation
and bylaws could make the following more difficult:

- the acquisition of us by means of a tender offer;

- the acquisition of us by means of a proxy contest or otherwise; or

- the removal of our incumbent officers and directors.

These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of us to first
negotiate with our board. We believe that the benefits of increased protection
of the potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure us outweigh the disadvantages of
discouraging such proposals because negotiation of such proposals could result
in an improvement of their terms.

ELECTION AND REMOVAL OF DIRECTORS. Our board of directors is classified
into three classes. The directors in each class serve for a three-year term, one
class being elected each year by our stockholders. This system of electing and
removing directors may tend to discourage a third party from making a tender
offer or otherwise attempting to obtain control of us because it generally makes
it more difficult for stockholders to replace a majority of the directors. In
addition, our by-laws provide that, except as otherwise provided by law or our
certificate of incorporation, newly created directorships

45
<PAGE>
resulting from an increase in the authorized number of directors or vacancies on
the board may be filled only by

- a majority of the directors then in office, though less than a quorum is
then in office; or

- by the sole remaining director.

STOCKHOLDER MEETINGS. Under our certificate of incorporation and bylaws,
only the chairman of the board, the president or a majority of the board of
directors may call special meetings of stockholders.

REQUIREMENTS FOR ADVANCE NOTIFICATION OF STOCKHOLDER NOMINATIONS AND
PROPOSALS. Our bylaws establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

DELAWARE ANTI-TAKEOVER LAW. We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203 prohibits
a publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
the person became an interested stockholder, unless the "business combination"
or the transaction in which the person became an interested stockholder is
approved in a prescribed manner. Generally, a "business combination" includes a
merger, asset or stock sale, or other transaction resulting in a financial
benefit to the interested stockholder. Generally, an "interested stockholder" is
a person who, together with affiliates and associates, owns or within three
years prior to the determination of interested stockholder status, did own, 15%
or more of a corporation's voting stock. The existence of this provision may
have an anti-takeover effect with respect to transactions not approved in
advance by the board of directors, including discouraging attempts that might
result in a premium over the market price for the shares of common stock held by
stockholders.

ELIMINATION OF STOCKHOLDER ACTION BY WRITTEN CONSENT. Our certificate of
incorporation and bylaws eliminate the right of stockholders to act by written
consent without a meeting, unless the consent is unanimous.

NO CUMULATIVE VOTING. Our certificate of incorporation and bylaws do not
provide for cumulative voting in the election of directors. As a result, the
holders of a majority of the shares of common stock can elect all of the members
of the board of directors.

UNDESIGNATED CAPITAL STOCK. The authorization of undesignated capital stock
will make it possible for our board of directors to issue preferred stock with
voting or other rights or preferences that could impede the success of any
attempt to change control of PEC Solutions.

LIMITATION OF LIABILITY AND INDEMNIFICATION PROVISIONS

As permitted by the Delaware General Corporation Law, our certificate of
incorporation provides that our directors shall not be personally liable to us
or our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability:

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

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

- under Section 174 of the Delaware General Corporation Law, relating to
unlawful payment of dividends or unlawful stock purchase or redemption of
stock; or

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

46
<PAGE>
As a result of this provision, we and our stockholders may be unable to obtain
monetary damages from a director for breach of his or her duty of care.

Our certificate of incorporation and bylaws provide for the indemnification
of our directors and officers to the fullest extent authorized by the Delaware
General Corporation Law. The indemnification provided under our certificate of
incorporation and bylaws includes the right to be paid expenses in advance of
any proceeding for which indemnification may be had, provided that the payment
of these expenses incurred by a director or officer in advance of the final
disposition of a proceeding may be made only upon delivery to us of an
undertaking by or on behalf of the director or officer to repay all amounts so
paid in advance if it is ultimately determined that the director or officer is
not entitled to be indemnified. If we do not pay a claim for indemnification
within 60 days after we have received a written claim, the claimant may at any
time thereafter bring an action to recover the unpaid amount of the claim and,
if successful, the director or officer will be entitled to be paid the expense
of prosecuting the action to recover these unpaid amounts.

Under our bylaws, we have the power to purchase and maintain insurance on
behalf of any person who is or was one of our directors, officers, employees or
agents, or is or was serving at our request as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against the person or incurred by the
person in any of these capacities, or arising out of the person's fulfilling one
of these capacities, and related expenses, whether or not we would have the
power to indemnify the person against the claim under the provisions of the
Delaware General Corporation Law. We intend to purchase director and officer
liability insurance on behalf of our directors and officers.

STOCK TRANSFER AGENT

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

SHARES ELIGIBLE FOR FUTURE SALE

After this offering, we will have 22,459,046 shares of common stock
outstanding. All of the shares we sell in this offering will be freely tradable
without restriction or further registration under the Securities Act, except
that any shares purchased by our affiliates, as that term is defined in
Rule 144, may generally only be sold in compliance with the limitations of
Rule 144, which is summarized below.

The remaining 18,959,046 shares, representing 84.4% of the common stock to
be outstanding after this offering, will be restricted shares under the terms of
the Securities Act. Restricted shares may be sold in the public market only if
registered or if they qualify for an exemption from registration under
Rules 144, 144(k) or 701 or other applicable exemption promulgated under the
Securities Act, which rules are summarized below. Giving effect to the lock-up
agreements described below, these restricted shares will be available for resale
in the public market as follows:

<TABLE>
<CAPTION>
NUMBER OF
SHARES DATE OF FIRST AVAILABILITY FOR RESALE
<C> <S>
181,428 Immediately after the date of this prospectus

266,742 90 days after the date of this prospectus

18,510,876 After 180 days from the date of the prospectus subject, in
some cases, to volume limitations
</TABLE>

Before this offering, there has been no public market for our common stock,
and we cannot predict what effect, if any, that market sales of shares of our
common stock or the availability of shares of our common stock for sale will
have on the market price of our common stock prevailing from time to time. Sales
of substantial amounts of our common stock in the public market could adversely
affect prevailing market prices and could impair our future ability to raise
capital through the sale of our equity securities.

RULE 144

In general, under Rule 144, beginning 90 days after the effective date of
the offering, a stockholder who has owned restricted shares for at least one
year is entitled to sell, within any three-month period, a number of these
restricted shares that does not exceed the greater of:

- one percent of the then outstanding shares of our common stock, or
approximately 224,590 shares immediately after this offering; or

- the average weekly trading volume in our common stock on the Nasdaq
National Market during the four calendar weeks preceding the sale.

In addition, our affiliates must comply with the restrictions and requirements
of Rule 144, other than the one-year holding period requirement, to sell shares
of common stock that are not restricted securities.

Under Rule 144(k), a stockholder who is not currently, and who has not been
for at least three months before the sale, an affiliate of ours who owns
restricted shares that have been outstanding for at least two years may resell
these restricted shares without compliance with the above requirements. The one-
and two-year holding periods described above do not begin to run until the full
purchase price is paid by the person acquiring the restricted shares from us or
an affiliate of ours.

48
<PAGE>
RULE 701

In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchase shares from us in
connection with a written compensatory stock or option plan is eligible to
resell such shares 90 days after the effective date of this offering in reliance
on Rule 144 but without compliance with some restrictions, including the holding
period, contained in Rule 144.

STOCK OPTIONS

We intend to file one or more registration statements under the Securities
Act 180 days after this offering to register an aggregate of approximately
7.9 million shares of our common stock underlying outstanding stock options or
reserved for issuance under our 2000 stock incentive plan, 2000 employee stock
purchase plan, 1987 Stock Incentive Plan and our 1995 Nonqualified Stock Option
Plan. We expect these registration statements will become effective upon filing,
and shares covered by these registration statements will be eligible for sale in
the public market immediately after the effective dates of these registration
statements, subject to the lock-up agreements described below.

LOCK-UP AGREEMENTS

Our officers and directors and certain other stockholders, who together will
hold 18,510,876 shares representing 82.4% of our outstanding capital stock after
this offering, have agreed that they will not, without the prior written consent
of Donaldson, Lufkin & Jenrette Securities Corporation, offer, sell, pledge or
otherwise dispose of any shares of our capital stock or any rights to acquire or
purchase, any of our capital stock or publicly announce an intention to effect
any of these transactions, for a period of 180 days from the date of this
prospectus.

Donaldson, Lufkin & Jenrette Securities Corporation currently has no plans
to release any portion of the securities subject to lock-up agreements. When
determining whether or not to release any portion of the securities subject to
lock-up agreements, Donaldson, Lufkin & Jenrette Securities Corporation will
consider, among other factors, the stockholder's reasons for requesting the
release, the number of shares for which the release is being requested and
market conditions at the time.

We will pay the offering expenses, estimated to be approximately $900,000.
We will pay to the underwriters underwriting discounts and commissions in an

amount the underwriters pay to us for each share of common stock.

An electronic prospectus is available on the Web site maintained by
DLJDIRECT Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation and a representative of the underwriters. Other than the prospectus
in electronic format, the information on this Web site relating to the offering
is not part of this prospectus and has not been approved or endorsed by us or
the underwriters, and should not be relied on by prospective investors.

David C. Karlgaard, Paul G. Rice and Alan H. Harbitter have granted to the
underwriters an option, exercisable for 30 days after the date of this
prospectus, to purchase up to 525,000 additional shares of common stock at the
initial public offering price less the underwriting discounts and commissions.
The underwriters may exercise this option solely to cover over-allotments, if
any, made in connection with this offering. To the extent the underwriters
exercise this option, each underwriter will be obligated, upon satisfaction of
certain conditions, to purchase a number of additional shares approximately
proportionate to that underwriter's initial purchase commitments.

We, together with David C. Karlgaard, Paul G. Rice and Alan H. Harbitter,
have agreed to indemnify the underwriters against liabilities, including
liabilities under the Securities Act, or to contribute to payments that the
underwriters may be required to make for these liabilities.

For a period ending 180 days from the date of this prospectus, we, our
executive officers and directors and certain other stockholders have agreed that
we and they will not, without the prior written consent of Donaldson, Lufkin &
Jenrette Securities Corporation:

- offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right
or warrant to purchase, lend or otherwise transfer or dispose of, directly
or indirectly, any shares of common stock or any securities convertible
into or exercisable or exchangeable for common stock; or

- enter into any swap or other arrangement that transfers all or a portion
of the economic consequences associated with the ownership of any common
stock.

Either of the foregoing transfer restrictions will apply regardless of
whether any such transaction described above is to be settled by delivery of
common stock or other securities, in cash, or otherwise. In addition, during
such lock-up period, we have also agreed not to file any registration statement
relating to, and each of our executive officers, directors and stockholders has
agreed not to make any demand for, or exercise any right relating to, the
registration of any shares of common stock or any securities convertible into or
exercisable or exchangeable for common stock without the prior written consent
of Donaldson, Lufkin & Jenrette Securities Corporation.

Prior to this offering, no public market has existed for our common stock.
We will negotiate the initial public offering price for our common stock with
the representatives, but the price may not reflect the market price for our
common stock after this offering. The factors considered in determining the
initial public offering price include:

- the history of and prospects for our industry in which we compete;

- our past and present operations;

- our historical results of operations;

- our prospects for future operational results;

- the recent market prices of securities of generally comparable companies;
and

- the general conditions of the securities market at the time of this
offering.

We have applied to have our common stock quoted on the Nasdaq National
Market under the symbol "PECS."

Other than in the United States, no action has been taken by us, the selling
stockholders or the underwriters that would permit a public offering of the
shares of common stock included in this offering in any jurisdiction where
action for that purpose is required. The shares included in this offering may
not be offered or sold, directly or indirectly, nor may this prospectus or any
other offering material or advertisements in connection with the offer and sale
of any shares of common stock be distributed or published in any jurisdiction,
except under circumstances that will result in compliance

51
<PAGE>
with the applicable rules and regulations of such jurisdiction. We advise
persons who receive this prospectus to inform themselves about and to observe
any restrictions relating to this offering and the distribution of this
prospectus. This prospectus is not an offer to sell or a solicitation of an
offer to buy any shares of common stock in any jurisdiction where that would not
be permitted or legal.

In connection with this offering, the underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
common stock. Specifically, the underwriters may over-allot this offering,
creating a syndicate short position. The underwriters may bid for and purchase
our shares of common stock in the open market to cover such syndicate short
positions or to stabilize the price of our common stock. In addition, the
underwriting syndicate may reclaim selling concessions from syndicate members
and selected dealers if they repurchase previously distributed common stock in
syndicate covering transactions, in stabilizing transactions or otherwise, or if
Donaldson, Lufkin & Jenrette Securities Corporation receives a report which
indicates that the clients of such syndicate members have "flipped" our common
stock. These activities may stabilize or maintain the market price of the common
stock above independent market levels. The underwriters are not required to
engage in these activities and may end any of these activities at any time.

At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 5% of the shares of common stock offered by this
prospectus for sale to our officers, directors, employees and their family
members and to business associates of PEC Solutions, Inc., including clients,
consultants and other friends. These persons must commit to purchase after the
registration statement has become effective but before the open of business on
the following business day. The number of shares available for sale to the
general public will be reduced to the extent these persons purchase the reserved
shares.

LEGAL MATTERS

Piper Marbury Rudnick & Wolfe LLP, Reston, Virginia, will pass upon the
validity of the shares of common stock on our behalf. Sachnoff & Weaver, Ltd.,
Chicago, Illinois, will pass upon legal matters for the underwriters.

NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES

COMPANY

Performance Engineering Corporation ("PEC") was incorporated June 25, 1985,
under the laws of the Commonwealth of Virginia. On January 1, 2000, PEC was
reincorporated, under the laws of the state of Delaware, as PEC Solutions, Inc.
("PEC Solutions" or the "Company"). The Company provides professional technology
services that enable government entities to use the Internet and other advanced
technologies to enhance productivity and improve services to the public. The
Company's primary clients are executive agencies and departments of the federal
government, the federal Judiciary and prime contractors to the United States
government. Contracts and subcontracts with these clients for 1997 were time and
materials contracts (47%), fixed-price contracts (31%) and cost-reimbursable
contracts (22%). For 1998, these contracts and subcontracts were time and
materials contracts (66%), fixed-price contracts (19%) and cost-reimbursable
contracts (15%). For 1999, these contracts and subcontracts were time and
materials contracts (62%), fixed-price contracts (23%) and cost-reimbursable
contracts (15%).

REVENUE RECOGNITION

The Company's revenues are derived primarily from contracts with the federal
government. Revenues on time and materials contracts are recognized based on
actual hours delivered at the contracted billable hourly rate plus the cost of
materials incurred. Revenues on fixed-price contracts are recognized using the
percentage-of-completion method based on costs incurred in relation to total
estimated costs. Revenues on cost-type contracts are recognized to the extent of
costs incurred in providing services plus a proportionate amount of the fee
earned. The fees under certain government contracts may be increased or
decreased in accordance with cost or performance incentive provisions that
measure actual performance against established targets or other criteria. Such
incentive fee awards or penalties are included in revenues at the time the
amounts can be reasonably determined. Provisions for anticipated contract losses
are recognized at the time they become known and estimable.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand and in banks. The Company
also considers all highly liquid investments with a maturity of three months or
less when purchased to be cash equivalents. As of December 31, 1998 and 1999,
cash equivalents included money market funds of approximately $5,009,662 and
$2,070,383, respectively.

CONCENTRATION OF CREDIT RISK

At times during the year, the Company maintains cash balances at financial
institutions in excess of Federal Deposit Insurance Corporation (FDIC) limits.
Management believes the risk in these situations to be minimal. In addition, the
Company had cash balances of $2,070,383 held in money market funds at local
financial institutions as of December 31, 1999. These funds are not insured by
the FDIC.

MARKETABLE SECURITIES

The Company determines the appropriate classification of marketable
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. The Company's marketable securities are categorized as
available-for-sale and held-to-maturity. Available-for-sale securities are
stated at fair value.

PEC SOLUTIONS, INC.

NOTES TO FINANCIAL STATEMENTS -(Continued)

1. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES -(CONTINUED)
PROPERTY AND EQUIPMENT

Property and equipment are stated at cost less accumulated depreciation. For
additions prior to January 1, 1999, depreciation is computed on property and
equipment using the double declining balance method over the estimated useful
lives of the assets, generally 3 to 5 years. Effective January 1, 1999,
depreciation is computed on property and equipment using the straight-line
method. Depreciation is computed on leasehold improvements using the
straight-line method over the shorter of the lease term or the useful life of
the respective assets.

LONG-LIVED ASSETS

The Company evaluates the recoverability of its long-lived assets in
accordance with Statement of Financial Accounting Standards No. 121, "ACCOUNTING
FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED
OF," (SFAS No. 121). SFAS No. 121 requires the recognition of impairment of
long-lived assets in the event the net book value of such assets exceeds the
future undiscounted net cash flows attributable to such assets. Impairment, if
any, is recognized in the period of identification to the extent the carrying
amount of an asset exceeds discounted net cash flows attributable to such
assets. Based on its most recent analysis, the Company believes that there was
no impairment of its property and equipment as of December 31, 1999.

CONTRACT ADVANCE PAYMENTS

The Company invoices the federal government for some of its contracts based
on provisional indirect cost rates. These invoiced amounts are adjusted when the
actual rates have been determined by audit. Other Federal government contracts
are billed periodically independent of the percentage of the contract actually
completed which, in some situations, results in funds being advanced to the
Company in excess of revenues earned.

COMMON STOCK SPLITS

Effective December 22, 1997, the Company's common stock was split 2-for-1.
Effective January 1, 2000, in connection with its reincorporation, the Company's
common stock was split 3-for-1. Effective March 1, 2000, the Company's common
stock was split 2-for-1. All prior share and per share information in the
financial statements has been restated to give effect to these stock splits.

STOCK-BASED COMPENSATION

The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion No. 25,
"ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES," (APB No. 25) and complies with the
disclosure provisions of Statement of Financial Accounting Standards No. 123,
"ACCOUNTING FOR STOCK-BASED COMPENSATION," (SFAS No. 123).

INCOME TAXES

The Company accounts for deferred income taxes using the liability method,
under which the expected future tax consequences of timing differences between
the book and tax basis of assets and liabilities are recognized as deferred tax
assets and liabilities.

NOTES TO FINANCIAL STATEMENTS -(Continued)

1. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES -(CONTINUED)
USE OF ESTIMATES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect certain reported amounts and disclosures.
Accordingly, actual results could differ from those estimates.

SEGMENT REPORTING

The Company operates as a single segment and will evaluate additional
disclosure requirements as it expands its operations.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS 133, as
amended, is effective for quarters beginning after June 15, 2000. Currently, the
Company does not use derivative financial instruments, therefore the adoption of
SFAS 133 is not expected to have a material impact on the Company's results of
operations or financial position.

RECLASSIFICATIONS

Certain amounts in the 1997 and 1998 financial statements have been
reclassified to conform to the 1999 presentation.

2. ACCOUNTS RECEIVABLE

Accounts receivable consisted of the following as of:

<TABLE>
<CAPTION>
DECEMBER 31,
-------------------------
1998 1999
<S> <C> <C>
Billed accounts receivable......................... $ 9,685,535 $11,854,428

----------- -----------
Accounts receivable, net........................... $10,852,341 $13,241,056
=========== ===========
</TABLE>

Unbilled accounts receivable consist of recognized recoverable costs and
accrued profits on contracts for which billings had not been presented to
clients as of the balance sheet date. Management anticipates the collection of
these amounts within 90 days of the balance sheet date. Payments to the Company
on contracts with agencies and departments of the Federal government are subject
to adjustment upon audit by the federal government. All years subsequent to 1995
are subject to federal government audit. Management believes the effect of audit
adjustments, if any, on periods not yet audited, will not have a material effect
on the financial statements.

The Company has a loan agreement with Bank of America which provides for a
line of credit with a limit of $2,700,000 at the prime rate charged by the bank
(7.75% and 8.5% as of December 31, 1998 and 1999). The note is collateralized by

5. STOCK OPTION PLANS

On February 1, 1987, the Company established an incentive stock option
agreement (the "agreement"), to attract, retain and reward employees and on
January 1, 1995 the Company established a nonqualified stock option plan (the
"plan", collectively "the plans") to attract, retain and reward key employees.
The plans are administered by the Board of Directors, which has the authority to
determine which officers and key employees are awarded options pursuant to the
plans and the related terms and option prices. The number of options available
for grant under the plans is limited to the number of Company common shares
authorized and available.

Each stock option granted pursuant to the plans has an exercise price equal
to the fair market value of the underlying common stock at the date of grant.
Each stock option granted under the agreement has a five-year term and a
two-year vesting period. Each stock option granted pursuant to the plan has a
ten-year term and no vesting period.

The Company adopted the disclosure requirements of SFAS No. 123, "Accounting
for Stock-Based Compensation," effective for the Company's December 31, 1999
financial statements. The Company applies APB Opinion No. 25 and related
interpretations in accounting for its plans. Accordingly, compensation cost has
been recognized for its stock plans based on the intrinsic value of the stock
option at date of grant (i.e., the difference between the exercise price and the
fair value of the Company's common stock).

Had compensation cost for the Company's stock-based compensation plans been
determined based on the fair value at the grant dates for awards under the plans

The weighted average fair value per share for stock option grants that were
awarded in fiscal years 1997, 1998 and 1999 was $0.23, $0.43, and $0.36,
respectively.

In January 2000, the Company established a stock incentive plan (the "2000
Plan"). Under the 2000 Plan, options to purchase 1,500,000 shares of common
stock are available for 2000. Beginning in 2001, the number of options eligible
for grant in each year will be equal to the sum of 6.25% of the number of
outstanding shares on January 1 of that year, plus the number of shares eligible
for grant in the prior year that were not granted. No more than 15,000,000
options may be granted during the 10-year term of the 2000 Plan.

In January 2000, the Company established an employee stock purchase plan
(the "Purchase Plan"). Under the Purchase Plan, employees, through payroll
deductions, are granted options to purchase shares of common stock at a price no
less than 85% of the fair market value of the common stock on the first trading
day of the option period or the date the shares of common stock are purchased.
There are 2,000,000 shares of common stock available for purchase under the
Purchase Plan.

6. BASIC EARNINGS PER SHARE AND DILUTED EARNINGS PER SHARE

Basic earnings per common share is computed on the basis of the
weighted-average number of common shares outstanding for the periods. Diluted
earnings per common share includes the weighted-average effect of dilutive
options outstanding during the periods. The weighted average number of shares
issuable upon the exercise of outstanding stock option assumes that the
applicable proceeds from such exercise are used to acquire treasury shares at
the average price during the periods.

Basic and diluted earnings per share for 1997, 1998, and 1999, were
determined as follows:

7. EMPLOYEE BENEFIT PLAN

During 1985, the Company established a qualified profit sharing plan in
accordance with Section 401(k) of the Internal Revenue Service Code. Under the
plan, the Company makes contributions out of profits of the Company based on an
amount determined at the discretion of the Board of Directors of the Company.
All full-time employees and part-time employees working at least 20 hours a week
are eligible to participate in the plan. Eligibility is restricted for new
employees, whom are not permitted to participate until the first day of the
first quarter following date of hire. The Company contributed $583,030,
$1,224,673 and $1,226,316 for 1997, 1998 and 1999, respectively.

8. SUPPLEMENTAL RETIREMENT PROGRAM

In December 1998, the Company adopted a funded Executive Supplemental
Retirement Program for a select group of management or highly compensated
employees. The Program allows these employees to defer a portion of their salary
and bonus. The Company has the option of adding additional amounts of deferred
compensation at its sole discretion. The Company contributions are vested after
five years. No employee deferrals were made in 1998. In 1999, employee deferrals
were $60,093. The Company contributed $105,446 and $99,367 to the Program in

14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

Section 145 of the Delaware General Corporation Law ("Section 145") permits
indemnification of directors, officers, agents and controlling persons of a
corporation under certain conditions and subject to certain limitations. Our
bylaws include provisions to require us to indemnify our directors and officers
to the fullest extent permitted by Section 145, including circumstances in which
indemnification is otherwise discretionary. Section 145 also empowers us to
purchase and maintain insurance that protects our officers, directors, employees
and agents against any liabilities incurred in connection with their service in
such positions.

At present, there is no pending litigation or proceeding involving any of
our directors or officers as to which indemnification is being sought nor are we
aware of any threatened litigation that may result in claims for indemnification
by any officer or director.

The form of Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification of our directors and officers by the
Underwriters, for certain liabilities arising under the Securities Act.

15. RECENT SALES OF UNREGISTERED SECURITIES

During the last three years, we have issued unregistered securities in the
transactions described below. These securities were offered and sold by us in
reliance upon the exemption provided for in Rule 701 of the Securities Act on
the basis that these options were offered and sold pursuant to a written
compensatory benefit plan. The sales were made without the use of an underwriter
and the certificates representing the securities sold contain a restrictive
legend that prohibits transfer without registration or an applicable exemption.

(1) Between January 1997 and February 2000, we have issued options to
our employees and directors exercisable for an aggregate of 4,890,630 shares
of common stock at exercise prices ranging from $1.10 to $3.18 per share

17. UNDERTAKINGS

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

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

The undersigned Registrant hereby undertakes that:

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

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