ITEM 1.           BUSINESS

General

     The Management's Discussion and Analysis of Financial Condition and Results
of Operations, and certain other portions of this report on Form 10-K, contain
trend analysis and other forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A
of the Securities Act of 1933 that involve risks and uncertainties. Those risks
and uncertainties, which are discussed elsewhere in this 10-K, include the
variability of government funding, changing geopolitical conditions, possible
changes in government procurement procedures, and the availability of highly
skilled and educated employees required by the Company. Accordingly, the
Company's actual results may differ significantly from those projected in the
forward-looking statements.

SPARTA, Inc. ("SPARTA" or the "Company") performs a wide range of scientific,
engineering and technical assistance services, both as a prime contractor and
subcontractor, primarily for the U.S. military services and other agencies of
the U.S. Department of Defense. The Company analyzes complex technological,
strategic and tactical issues necessary to define the requirements for new
tactical and strategic weapons and defense systems, including systems for the
Ballistic Missile Defense ("BMD"); develops engineering solutions to accommodate
conflicting technological, schedule, and budgetary requirements; and assists in
the design, integration, evaluation and testing of software and hardware
components. These activities include the development of sophisticated computer
simulations, applications software, and functional algorithms depicting all
aspects of various weapons and defense systems and their operation, and the
design, fabrication, and testing of prototype hardware. SPARTA's technology
development activities include research and development for laser systems;
distributed interactive computer simulations; software development; advanced
signal processing; battle management/command, control, and communications;
artificial intelligence; information security; aircraft avionics; test range
data acquisition; advanced materials and production technology; and composite
materials. SPARTA also manufactures composite parts for aircraft and missile
systems.

      The Company was originally incorporated in the State of Alabama in August
1979 under the name SPARTA, Inc. ("SPARTA Alabama"). On December 8, 1989, the
Company reincorporated in Delaware. In connection with the re-incorporation,
each outstanding share of SPARTA Alabama Common Stock, $.02 par value, and each
share of SPARTA Alabama Preferred Stock, $.02 par value, was converted into one
share of Common Stock, $.01 par value, of the Company. In addition, all options
to purchase Common Stock or Preferred Stock of SPARTA Alabama were converted
into options to purchase an equal number of shares of Common Stock of the
Company. Certain historical information contained herein and described as
relating to the Company reflects the operations of SPARTA Alabama prior to
December 8, 1989.

      In 1995, a new subsidiary, Commercial Technology, Inc. ("CTI"), was formed
and in 1996, 1997, and 1998 did business as SPARTA Marine Instrumentation. In
the last quarter of 1998, all active contracts in CTI were contractually
assigned and assumed by another entity unaffiliated with the Company. As used in
this report on Form 10-K, all references to the Company or SPARTA include,
unless the context indicates otherwise, the Company, SPARTA Alabama and CTI.

      Performance of scientific, engineering, technical and other services,
under contracts with Department of Defense ("DOD") agencies, either as a prime
contractor or subcontractor, accounted for approximately 83% of the Company's
revenues in the fiscal year ended January 2, 2000. Contracts to other non-DOD
government agencies like NASA accounted for an additional 14% of the Company's
revenues and 3% of the Company's revenues was commercial work.


      In the area of strategic defense systems, the Company provides a wide
range of scientific, engineering, and analytical services and technical support
to various organizations of the Department of Defense. These services




                                       1
<PAGE>   4




and support are provided both directly to these agencies or indirectly via
subcontracts from major defense and aerospace contractors. The agencies have
primary responsibility for developing strategic defense systems which include
(i) sophisticated reconnaissance and surveillance equipment, (ii) long range
missile and weapons systems to protect the United States from attack and provide
the United States with retaliatory capability, (iii) theater missile defense,
and (iv) command, control, communication, and intelligence systems which control
and integrate the operations of strategic reconnaissance, surveillance, and
weapons systems.

      The Ballistic Missile Defense Organization ("BMDO") was established as a
separate agency of the Department of Defense to integrate into a single agency
all the military activities carried out for defense against ballistic missiles
by the U.S. Air Force, the U.S. Army and the U.S. Navy. The BMDO is an umbrella
organization that funds and supervises technology and system development for
defensive systems which defend against both nuclear and non-nuclear ballistic
missiles. Contracts for scientific, engineering and technical assistance
services for the BMDO have historically been a significant source of revenues
for the Company and as a result, the Company was, and remains, heavily dependent
on its BMD programs. In recent years, the Company has attempted to diversify its
business base to reduce its dependence on BMD, primarily due to the historical
uncertainties of those programs. However, recent congressional concern about the
proliferation of nuclear weapons has stabilized government funding in this area.
Because of this, BMD continues to be a steady and large part of the Company's
business. In 1999, 1998, and 1997, BMD revenues accounted for 37%, 39% and 40%,
respectively, of sales. Government BMDO funding for government fiscal year
("GFY") 1999 was $4.2 billion, up from $3.8 billion in GFY 1998. The program, as
restructured starting in GFY 1994, emphasized Theater Missile Defense ("TMD")
rather than National Missile Defense ("NMD"). On July 23, President Clinton
signed the National Missile Defense Act of 1999, which calls for the
implementation of a system to protect against limited attacks "as soon as is
technologically possible."

      The BMDO budget appropriation for GFY 2000 is $3.8 billion with some
renewed emphasis on NMD, as well as continuing support of TMD. Governmental
budget decisions, international events, proliferation of nuclear weapons, and
international arms negotiations, over which the Company has no influence, will
affect BMD. As a result, there can be no assurance that the present commitment
of the United States to BMD will materialize or that funding for BMD programs in
general will not be reduced. However, strategic defense programs, under the
direction of various military and Defense Department agencies, have been in
existence for more than 40 years. The Company believes that the threat posed to
the U.S. by a limited number of warheads, which is the impetus for the NMD Act
of 1999, will result in the continued funding of strategic defense programs by
these agencies.

      The Company, which is primarily owned by its employees and directors, has
assembled a staff of highly-trained scientists, engineers, and analysts who hold
undergraduate and advanced degrees in a wide range of disciplines. Accordingly,
the Company has been able to compete for large, multitask projects with
multidisciplinary requirements. The Company has employees in twenty-two offices,
in three companies, and at six government facilities. The offices are in 10
states in proximity to government agencies and private contractors for which
services are performed. The Company's three business sectors are given
substantial autonomy in identifying and pursuing business opportunities for the
Company.

 Industry Background

      A substantial portion of the U.S. defense budget is devoted to the
development of new weapons and defense systems and system upgrades. However,
development of new weapons and defense systems and upgrades requires
considerable scientific, engineering, and analytical expertise which is often
beyond the resources of the government agencies which are responsible for
development of those systems.


      As a result, U.S. government defense and military agencies have relied, in
part, on outside service firms such as the Company to assist them in the
performance of their responsibilities. Such firms provide analytical, technical
and engineering support services throughout the life cycle of complex weapons
and defense systems. This life-cycle typically begins with a requirements
definition phase in which particular strategic or tactical






                                       2
<PAGE>   5

needs, opportunities, and objectives are identified and the technological
requirements and configuration or design of a system are defined in terms of
those needs, opportunities, or objectives. Requirements definition involves
analyses of numerous and seemingly diverse factors, including (i) the current
state of technology; (ii) the performance of existing weapons and defense
systems; (iii) developments or changes in military and weapons capabilities of
other countries which can create potential new military threats that must be
counteracted; (iv) changes in US strategic or tactical policies and the effects
of geopolitical developments, which may require changes in defensive strategies
or tactics; and (v) budgetary and economic considerations. The life cycle
continues through the development, testing, manufacture, deployment, and
maintenance of systems and technology.

      Scientific, engineering, and technical assistance firms, such as the
Company, play a significant role in this development process by gathering and
analyzing complex data; developing design alternatives and solutions to
accommodate conflicting requirements; establishing development priorities;
assisting in the preparation of requirements for various programs and in the
evaluation of bids received for those programs; and developing software and
other systems for testing and validating weapons system hardware and software.
Finally, such firms are relied on to develop software and other systems which
simulate combat situations for training of military personnel in the operation
of the new or upgraded weapons and defense systems.

      In recent years there have been numerous consolidations and mergers in the
defense industry. None of these has adversely impacted the Company's business
activities. However, there is no way to assess the impact to the Company of any
future mergers. In addition, there has been a strong movement in acquisition
reform resulting from the Federal Acquisition Streamlining Act ("FASA").
Although most experts agree that procurement reform has not been very favorable
to small business, it has not adversely impacted the Company's business to date.
Another initiative within the government is to out-source all services, except
those services that are inherently governmental functions, to the maximum extent
possible. Since the Company has a significant engineering service business, this
initiative should be favorable to the Company in the future. And finally, the
government is now using mostly multiple award/task order type contracts for
engineering and advisory type services. Because of this, there is greater
uncertainty that the Company will receive task orders even after it has been
awarded one of these basic contracts.

Company Strategy

      The Company's strategy has been to build a high quality professional staff
of scientists, engineers, technicians, and analysts who have diverse backgrounds
and the experience necessary to enable the Company to bid effectively on and to
capture a significant number of defense service contracts. The Company has
approximately 753 employees, of which approximately 70% have earned
undergraduate and/or advanced degrees in a wide variety of disciplines including
aeronautical, electrical, and mechanical engineering; physics; mathematics;
computer science; business management; and management information systems.

      The Company relies heavily on its senior management and professional staff
to obtain contracts that involve development of new systems configurations and
technologies. Such contracts are important to the future success of the Company
because they provide the Company's professional staff with the opportunity to
broaden its expertise and provide the Company with the opportunity to hire new
personnel who have backgrounds in areas outside of the Company's existing
expertise. The addition of such individuals enables the Company to bid on and
obtain contracts in new areas and establish relationships with additional
agencies in order to broaden its sources of business and enhance its ability to
secure larger contracts. During the past eight years, the Company has succeeded
in obtaining larger contracts in more diverse areas, including test and training
range support for the U.S. Air Force, evaluation of foreign military systems for
the Army, computer security work for the FBI, and range facility information
systems support work for NASA.


      Due to the size, complexity, and multidisciplinary requirements of many
government contracts, teaming arrangements among defense contractors are common,
with one contractor serving as the prime contractor and others acting as
subcontractors. The Company will continue to follow the practice of teaming with
other






                                       3
<PAGE>   6

government contractors to bid on procurements which require capabilities in
areas outside of the Company's expertise to enable the Company to obtain
contracts for larger programs in which the Company might not otherwise be able
to participate. Given the recent government trend for less reliance on service
companies to oversee the work of system development contractors, the Company has
been and will continue to pursue subcontractor roles from the large prime
contractor system developers. The Company will also continue to pursue small
business set-aside programs. The Company expects to remain qualified for small
business programs for a few more years. The Company is a small business in most
of its business areas because the threshold for contracts is typically 1,000
employees or less.

      Over the years, the Company has worked on military programs and has
developed certain technologies for military applications. The Company is now
pursuing the development of products and services that exploit these military
technologies in the commercial marketplace. Significant investments were made in
1996, 1997, and 1998 for these technologies. In 1999, investment in these
technologies continued but at a reduced rate. Such technologies include lasers
for interferometers, lasers for ordnance and mine neutralization, secure
communications, advance signal processing software used for filtering and
composite materials. There were no significant sales of these technologies or
products in the commercial marketplace in 1999.

Organization

      No organizational changes were made in 1999. In 1999, the Company
continued to be organized in the following three sectors: (1) Information
Systems, (2) Defense & Space Systems and (3) Hardware Systems. This approach,
implemented in 1996, integrated the Company's capabilities and resources for key
business targets and provided dedicated and focused business development
leadership for each of those business areas. Shown below is a summary of the
business areas of each sector:

      Defense and Space Systems Sector - This sector performs systems
formulation, analysis, engineering, and design for advanced military and space
systems.

      Hardware Systems Sector - This sector performs engineering services and
hardware analysis, design, development and production of products for military
and commercial applications.

      Information Systems Sector - This sector works on networked computer and
communication systems, software and hardware technologies, and provides services
and software products for government and commercial applications.

Marketing

      The Company's marketing approach begins with the development of
information concerning the present and future needs of various military and
intelligence agencies of the U.S. government, and certain civilian agencies and
prime contractors. Such information is gathered in the course of contract
performance and from formal or informal briefings, participation in the
activities of professional organizations and from published literature. The
Company then evaluates this information, and teams of Company scientists,
engineers, and analysts are formed along functional, geographic, and other lines
in order to devise and implement the best means of taking advantage of available
business opportunities. This occasionally includes the preparation of
unsolicited proposals responsive to the perceived needs of current and
prospective customers, but more often includes responding to formal
solicitations from various U.S. government agencies as discussed below.


      The Company places significant emphasis on client satisfaction, which is
essential to the development of repeat business. Past performance is now a
government mandated award criteria factor. To facilitate promptness of service
and interaction between the Company's professional staff and government,
civilian, and military personnel responsible for weapons and defense systems
programs, the Company has established offices at twenty-two locations in
proximity to the agencies and other contractors for which the Company provides
services. The Company also has employees on-site at government customer
facilities in four locations. The







                                       4
<PAGE>   7

Company's business sectors are given substantial autonomy in identifying and
pursuing business opportunities for the Company. All staff members are
encouraged to avail themselves of the broad diversity of expertise at other
offices within the Company to ensure that the highest quality of service is
provided to the Company's customers.

      The Company frequently forms teaming arrangements with other defense
contractors to bid on large, complex, and multidisciplinary contracts. The
teaming arrangements are also designed to broaden the Company's business base or
to penetrate new market areas and technologies. The Company teams with other
corporations both as a prime and a subcontractor. Corporations which have acted
as subcontractors to the Company include Science Applications International
Corporation, Woodside Summit Group, Nichols Research, TRW, and Camber
Corporation, among others. Companies for which the Company has acted as a
subcontractor include Lockheed Martin, TRW and Raytheon, among others.

U.S. Government Contracts

      Approximately 97% of the Company's fiscal year 1999 revenues were derived
from contracts or subcontracts for the benefit of departments or agencies of the
U.S. government, primarily the military services and other agencies of the
Department of Defense. The Company's business is performed principally under
cost reimbursement, fixed price, and fixed rate time and materials contracts.
Most of the cost reimbursement contracts are of the task order or delivery order
type.

      Cost reimbursement contracts include cost-plus-fixed fee and
cost-plus-award fee contracts. These contracts provide for reimbursement of
costs, to the extent allocable and allowable under applicable regulations, and
payment of a fee, which may either be fixed by the contract (cost-plus-fixed
fee) or the customer's subjective evaluation of the Company's work
(cost-plus-award fee). Under U.S. government regulations, certain costs,
including financing costs, are not reimbursable. In a cost reimbursement
contract, the Company can incur an actual loss only if unreimbursable costs
exceed the fixed or award fee.

      Under firm fixed price contracts, the Company agrees to perform certain
work for a fixed price and, accordingly, realizes the benefit or detriment
occasioned by decreased or increased actual costs of performing the contract.
Under fixed price (level-of-effort) contracts, the Company agrees to perform
certain work for a fixed price and an agreed upon level of effort. For example,
a given contract may provide for the number of hours to be spent by the Company
on the contract. Fixed price (level-of-effort) contracts are less risky than
firm fixed price contracts. If the Company uses all the agreed upon
level-of-effort, it may stop work and receive the entire payment, regardless of
whether all the work was completed. Under a fixed rate time and materials
contract, the customer agrees to pay a specific negotiated rate for each hour
worked or performed against a task order under the contract and to reimburse
material "at cost".

      Greater risks are involved under firm fixed price contracts than under
fixed price (level-of-effort) contracts, fixed rate, time and materials
contracts and other types of cost-reimbursable contracts. Also, less risk is
involved in firm fixed price contracts relating to the delivery of analytical
results compared to the same type of contracts relating to hardware. At this
time, the Company has less than 5% of its revenue resulting from firm fixed
price contracts relating to the delivery of hardware. Most of the Company's
contracts are low risk fixed price (level-of-effort); cost reimbursement; and
fixed rate, time and materials contracts.

      All cost reimbursement contracts relating to services or products supplied
to government agencies are subject to audits and adjustments. Such audits
include both an audit of the contractor's indirect contract costs on a fiscal
year basis, as well as an audit of the direct contract costs relating to each
individual contract. The government does not adhere to any firm schedule with
respect to its conduct of these audits. Rather, the scheduling of such audits is
dependent on the resources available to the Defense Contract Audit Agency
("DCAA") from time to time and the existence of higher priority projects. The
Company's indirect contract costs have been audited by and settled with the DCAA
through the fiscal year ended January 2, 1998 (fiscal year 1997). Indirect
contract costs for periods subsequent to fiscal year 1997 have been recorded at
amounts which




                                       5
<PAGE>   8


are expected to be realized upon final settlement. It's expected that fiscal
year 1998 will be audited and settled with the Government in fiscal year 2000.

      The Company's contracts may be terminated, in whole or in part, at the
convenience of the customer (as well as in the event of default). In the event
of a termination for convenience, the customer is generally obligated to pay the
costs incurred by the Company under the contract plus a fee based upon work
completed. There were no contracts terminated in 1999. The Company does not
anticipate any termination of programs and contracts in 2000. However, no
assurances can be given that such events will not occur. Changes in government
procurement policies relative to small businesses or a significant reduction in
government expenditures for services of the type provided by the Company also
would materially affect the revenues and income of the Company.

      In addition to the right of the U.S. government to terminate contracts for
convenience, U.S. government contracts are conditioned upon the continuing
availability of congressional appropriations. Congress usually appropriates
funds on a fiscal year basis, even though contract performance may take several
years. Consequently, at the outset of a major program, the contract is usually
partially funded and additional monies are normally committed to the contract by
the procuring agency only as Congress makes appropriations for future years.
These appropriations are therefore subject to changes as a result of increases
or decreases in the overall Department of Defense budget. The Company's business
can also be affected by the 2000 national elections resulting from changes in
the Administration or leadership in Congress. It also can be affected by any
significant delay between Congress and the Administration in reaching a defense
budget accord for government fiscal year 2001.

</TABLE>

      Funded backlog represents all current contracts expected to be performed
during the next 12 months for which the Company has received funding. Unfunded
12-month backlog includes the 12-month expected value of future incremental
funding on existing or negotiated contracts. As a result, and in part due to
U.S. government funding practices, most of the Company's funded backlog at any
given date is represented by work that will be performed within twelve months.

      Although the Company's backlog has, in the past, generally been indicative
of its future revenues, there can be no assurance that this will continue. The
Company's backlog is typically subject to variations from year to year as
contracts are completed, major existing contracts are renewed, or major new
contracts are awarded. Additionally, all U.S. government contracts included in
backlog, whether or not funded, may be terminated at the convenience of the U.S.
government.

Competition

      The business in which the Company is involved is very competitive and
requires highly skilled and experienced technical personnel with appropriate
levels of U.S. government security clearances. Substantially all of the
Company's new business is acquired as a result of formal competitive
solicitations, in which contracts are awarded on the basis of technical and
management capabilities, cost and past performance. There are many companies
that compete in the service and technology areas and research and development
areas in which the Company is engaged. Competition among these companies is
intense because, among other things, capital requirements and other barriers to
entry are minimal and a substantial number of contracts are competitively bid,






                                       6
<PAGE>   9

which enables less established firms to capture contract awards based on price.
Technical capability continues to be an important criterion for awarding
contracts, but cost and past performance have increased in importance in recent
years. Since an important role of firms such as the Company is to develop
requirements for various programs and even, occasionally, to evaluate bids from
weapons systems manufacturers on behalf of government defense procurement
agencies in response to those requirements, conflict-of-interest considerations
usually preclude weapons systems manufacturers from competing for scientific,
engineering and technical assistance service contracts. Principal competitive
factors are technical competence and expertise, cost, and the reputation of the
firm based on prior performance. In addition, project-related experience is an
award criterion, and firms that have performed services in earlier phases of a
project generally have an advantage in obtaining follow-on contracts for later
phases. The Company believes the skills of its technical personnel are the key
to its growth and competitive position in its industry. See "Business-Industry
Background" and "Business-Marketing."

Patents and Proprietary Rights

      The Company, at present, holds a small number of patents. All of these
patents are related to defense business conversions, some of which the Company
plans to exploit in the commercial marketplace. The Company believes that its
competitive position in its core business areas is not dependent on these
patents, or on copyright or trade secret protection, and that the success of the
Company depends primarily on the technical competence and managerial and
marketing ability of the Company's personnel.

Employees

      Most of the Company's employees are highly skilled and educated.
Approximately 70% of the Company's employees have college degrees, and 30% hold
advanced degrees, in a wide variety of disciplines, including aeronautical,
electrical and mechanical engineering, physics, chemistry, mathematics, computer
sciences and business and management. The Company's professional staff also
includes specialists in systems analysis, scientific simulation, data
processing, software design and development, and hardware development, testing,
evaluation and integration. The Company believes that one of its strengths,
which derives from the diverse backgrounds and training of its employees, is its
ability to apply multidisciplinary approaches to the projects it undertakes.

      The Company's primary resource is its technical staff and support
personnel. The Company believes its future success depends upon its ability to
retain and motivate its personnel and attract qualified new employees. In 1999,
the Company experienced a higher turnover of employees than in 1998, about the
same rate as in 1997. Some of the improvement in 1998 was attributed to an
organized Company objective to improve turnover. Although the same effort was
made in 1999, the turnover rate increased again due to the high demand for
technical staff in both the commercial marketplace and the government contractor
marketplace. The Company was able to attract and hire 213 full-time employees in
1999 to replace 172 terminating employees and increase full-time employees by
41. The Company believes that continuation of strong growth is the key to
recruiting and retaining a highly qualified staff. Such growth will provide
greater opportunities for advancement within the Company, enhance its employee
stock ownership program, and maintain its other incentives at industry
comparative levels. Notwithstanding continued growth and the associated strong
compensation incentives that result from such growth, there is a shortage of
certain technical personnel across the country that the Company needs to perform
in its business areas. It is uncertain if the Company will be able to reduce
turnover in 2000 like it did in 1998 or achieve its recruitment goals. Future
growth is dependent on achieving these goals.

      At January 2, 2000, the Company employed 753 effective full-time
employees, a majority of which are based in the Company's facilities in
California, Virginia, and Alabama. The Company believes that its employee
relations are good, and it has not experienced any labor disputes or work
stoppages.

ITEM 2.           PROPERTIES

      The Company's corporate office, comprised of approximately 12,300 square
feet of office space leased through May, 2003, are located in Laguna Hills,
California. The Company's leased offices, aggregating approximately 256,000
square feet in 22 locations in 10 states, include major offices in the cities of
Huntsville, Alabama; San Diego, California; Lancaster, California; El Segundo,
California; La Jolla, California; Billerica, Massachusetts; Rosslyn, Virginia;
McLean, Virginia; Raleigh, North Carolina; Columbia, Maryland; Colorado Springs,
Colorado; and Orlando, Florida. Leases on these and other Company facilities
expire at various times during the next eight years. The aggregate annual rent
paid by the Company for all of its offices and facilities during the fiscal year
ended January 2, 2000, was approximately $3,849,000. The Company believes that
the existing facilities are adequate to meet its needs for the foreseeable
future.

ITEM 5.           MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
                  MATTERS

Lack of Public Market: Internal Repurchase Program

      Except as noted below, its current employees and directors primarily own
the Company. Accordingly, the Company's 1997 Stock Plan (the "Stock Plan") and
the Company's Certificate of Incorporation place restrictions on the
transferability of the Company's Common Stock and grant the Company the right to
repurchase the shares held by any stockholder whose association with the Company
terminates. For these and other reasons, no public market currently exists for
the Company's securities, and it is not likely that a public market will develop
in the foreseeable future. However, in order to provide some liquidity for the
shares of Common Stock owned by the Company's stockholders, the Company has
established and maintains a program which permits the Company's stockholders to
offer all or any portion of their shares (except shares of "unvested" stock) for
sale to the Company on February 21, May 21, August 21 or November 21 of any year
(each a "Stock Repurchase Date") or at such other interim dates as the Board of
Directors of the Company may designate from time to time, at a per share price
equal to the Formula Price (as hereinafter defined) as of such Stock Repurchase
Date.

          The Company's repurchase program is a voluntary program on the part of
the Company, and the Company's stockholders therefore have no right to compel
the Company to repurchase any of the stockholders' shares. Moreover, the number
of shares that the Company may repurchase is subject to legal restrictions
imposed by applicable corporate law affecting the ability of corporations
generally to repurchase shares of their capital stock. In addition, the number
of shares which the Company may repurchase is subject to a self-imposed
quarterly repurchase limitation which is designed to ensure that the Company's
repurchase of its shares from time to time does not materially impair the
Company's financial condition. The Board of Directors may approve waivers to the
self-imposed quarterly repurchase limitation.


      The Company's policy prior to 1994 was to buy back the stockholdings of
all individuals leaving the Company, so as to retain all stockholdings among
active employees. The 40% reduction in the Company's staff level during 1993 and
1994 resulted in the termination of employees who held, in the aggregate,
approximately


                                       8
<PAGE>   11


30% of the Company's total Common Stock then outstanding. Consequently, in April
of 1994, the Company temporarily suspended the policy of repurchasing all of the
stock held by terminating employees so as not to deplete stockholders' equity.
In 1997, it again became the Company's policy to repurchase the stockholdings of
terminating employees. In support of this policy the Board of Directors
authorized the Plan Administrator to issue, at his discretion, promissory notes
to repurchase terminating employee stock. One new promissory note was issued in
1998 and eight new promissory notes were issued in 1999 to repurchase stock with
a value of $195,000 and $1,114,000, respectively. The amount of stock held by
former employees decreased from 4.9% (305,700 shares) at the end of 1998 to 4.8%
(291,136 shares) at the end of 1999.

      In November 1994, the Company entered into a Stock Purchase Agreement (the
"Agreement") with Science Applications International Corporation ("SAIC"), under
which SAIC was obligated to buy, during the first year of the Agreement, shares
of the Company's Preferred Stock with an aggregate price of $1,200,000. Under
the Agreement, SAIC also has the option, but not the obligation, to buy
additional shares of Preferred Stock, provided that SAIC's total purchases
during any quarter may not exceed $600,000, and provided further, that the total
number of shares of Preferred Stock purchased during any quarter may not exceed
the total number of shares of Common Stock offered to the Company for repurchase
by the Company's existing stockholders. The purchase price for all shares
purchased under the Agreement by SAIC is equal to the then current Formula Price
applicable to the Company's Common Stock. The Agreement provides that SAIC's
rights to purchase Preferred Stock will be suspended if and to the extent that
any purchase would cause the aggregate number of shares of the Preferred Stock
held by SAIC to exceed 19.9% of the total capital stock of the Company then
outstanding. In any event, SAIC's rights to purchase shares of the Company's
Preferred Stock under the Agreement will terminate on the tenth anniversary of
the Agreement, or earlier upon the occurrence of certain specified events. Under
the Agreement, if SAIC's ownership of shares of the Company's Preferred Stock
causes the Company to cease to be considered a "small business" for purposes of
any governmental program or award, the Company will have the option to
repurchase the Preferred Stock then held by SAIC at a price per share equal to
the then current Formula Price. The Agreement also grants SAIC the right to
require the Company to repurchase all of the Preferred Stock held by SAIC at the
then current Formula Price. Repurchase of the stock shall be in cash to the
extent that such cash repurchase does not cause the Company to violate its
self-imposed stock repurchase limitation. In that event, that portion which
cannot be paid in cash shall be paid in a subordinated promissory note. The
Company has used the proceeds from sales of Preferred Stock under the Agreement
to improve the liquidity of the holders of the Company's Common Stock. SAIC
discontinued its purchase of Company Preferred Stock in the November 1996, Stock
Repurchase Date. The Company began repurchasing the stock held by SAIC starting
with the May 21, 1999 Stock Repurchase Date, using funds as available within the
stock repurchase limitation. As of January 30, 2000, SAIC owned 430,698 shares
of Preferred Stock, which represented 6.9% of the total capital stock
outstanding. It is the Company's intent, with which SAIC agrees, to continue
repurchasing stock held by SAIC using funds as available within the quarterly
stock repurchase limitation.

Formula Price

      The Formula Price is based upon a formula (the "Formula") established by
the Company's Board of Directors, and which is subject to revision by the Board
of Directors from time to time.

      The Formula, as currently in effect, provides that the Formula Price is
equal to the sum of (i) a fraction, the numerator of which is the sum of the
stockholders' equity of the Company at the end of the fiscal quarter immediately
preceding the date on which a Formula Price revision is to occur ("SE"), the
aggregate principal amount of the long term portion of the Company's long term
subordinated promissory notes at the end of such fiscal quarter ("SN"), and the
aggregate exercise price of all stock options which were exercisable as of the
end of such fiscal quarter ("CX"), and the denominator of which is the sum of
the number of issued and outstanding shares of Common Stock and Preferred Stock
of the Company ("SI") and the number of shares of Common Stock issuable upon the
exercise of stock options which are exercisable ("SV") at the end of that fiscal
quarter, and (ii) the product of 7 multiplied by the "future growth factor"
("FG"), multiplied by the average annual "earnings per share" of the Company for
the eight fiscal quarters immediately preceding the price revision



                                       9
<PAGE>   12


("A"). (For this purpose, "earnings" include both net income and the tax
benefits to the Company from option exercises, and "shares" include both
outstanding shares and shares subject to vested stock options.) The "future
growth factor", or "FG", is the lesser of 1.5 or the number obtained by dividing
(a) the sum of the Company's gross profit for the four fiscal quarters
immediately preceding the date on which the price revision occurs, and the
projected gross profit for the four fiscal quarters immediately following the
end of such prior period by (b) the Company's gross profit during the eight
fiscal quarters immediately preceding the price revision, and squaring the
quotient so obtained. The Formula Price, expressed as an equation, is as
follows:

                      Formula Price = SE + SN + CX + (7FG x A)
                                      ------------
                                        SI + SV

Where:

      SE = Stockholders' equity which includes all common and preferred stock
      SN = Aggregate principal amount of subordinated notes (long term portion)
      CX = Aggregate exercise price of vested stock options
      SI = Number of common and preferred shares issued and outstanding
      SV = Number of shares subject to vested stock options
      FG = The lesser of 1.5 or gross earnings over the past twelve months
           plus projected gross earnings over the next twelve months divided by
           gross earnings over the past twenty-four months, the quotient of
           which is squared
      A  = Average annual "earnings per share" for the preceding eight quarters

      For purposes of the Formula, projected gross profit is determined by the
Company's CEO based on information provided monthly by each of the Company's
Division Managers concerning all contract proposals which have been sent to
customers for evaluation and source selection by his or her division. This
information includes expected contract value, period of performance, funding
profile, expected fee/profit, probable award date, and "probability of win"
assessment. This information is then reviewed and revised by the Company's
Operation Managers and Sector Presidents before submission to the Chief
Executive Officer.

      The Formula Price does not include liquidity as a factor in determining
the stock price. However, it should be noted that any extended period of
non-liquidity might require the Board of Directors to make a change in the
Formula Price to factor in the lack of liquidity. The Formula Price is reviewed
periodically (usually in April of each year) by an independent outside appraisal
firm to see that the Formula is producing a price within a range of fair market
value. It was last reviewed in April of 1998. The results of that review
determined that the Formula was producing a fair market value.

      The Formula Price is calculated not less than once each fiscal quarter, in
January, April, July and October of each year. Such calculations are based on
unaudited financial information as of the end of the last full fiscal quarter
immediately proceeding the date on which the Formula Price is recalculated. The
Company, without independent review, prepares such information. Consequently,
from time to time certain of the information used to calculate the Formula Price
as of a given date may subsequently be adjusted. However, to date all such
adjustments have been immaterial in amount and, accordingly, no retroactive
adjustment of the Formula Price has ever been made.

      Immediately following each recalculation of the Formula Price, each of the
Company's stockholders is given written notification of the new Formula Price,
which notification sets forth in detail the calculations by which the new
Formula Price has been determined.

Price Range of Common Stock

      Shares which are repurchased by the Company, either under the repurchase
program referred to above or in connection with the termination of a
stockholder's association with the Company, are generally repurchased



                                       10

at a price which is equal to the Formula Price then in effect. The following
table sets forth information regarding the Formula Price of the Common Stock,
rounded to the nearest cent, for the periods beginning on the dates indicated:

Dividend Policy

      The Company's present policy is to retain earnings for the operation and
expansion of its business. The Company has not paid cash dividends on its Common
Stock or Preferred Stock and does not anticipate that it will do so in the
foreseeable future. The Company's bank loan agreement prohibits the payment of
dividends by the Company without the bank's prior consent.

Record Holders

      As of January 30, 2000, there were approximately 617 holders of record of
the Company's Common Stock.

Repurchase Rights of the Company, Restrictions on Transferability

    All shares of the Company's Common Stock are subject to the Company's right
(but not obligation) to repurchase such shares in the event of a termination of
the holder's association with the Company. All shares of the Company's Common
Stock are also subject to (i) the Company's right of first refusal to purchase
such shares in the event a holder desires to transfer them and (ii) other
significant restrictions on transferability set forth in the Company's
Certificate of Incorporation. Substantially identical repurchase rights and
transfer restrictions are contained in the Stock Plan and are applicable to all
shares issued under that Plan.

ITEM 7.         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                RESULTS OF OPERATIONS

     The Management's Discussion and Analysis of Financial Condition and Results
of Operations, and certain other portions of this report on Form 10-K, contain
trend analysis and other forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A
of the Securities Act of 1933 that involve risks and uncertainties. Those risks
and uncertainties, which are discussed elsewhere in this 10-K, include the
variability of government funding, changing geopolitical conditions, possible
changes in government procurement procedures, and the availability of highly
skilled and educated employees required by the Company. Accordingly, the
Company's actual results may differ significantly from those projected in the
forward-looking statements.

       Revenues increased 17.9%, 14.3% and 26.1% over the prior year in 1999,
1998 and 1997, respectively. Growth of 127.6% in National Aeronautics and Space
Administration ("NASA") programs, 52.2% in Army Ballistic Missile Defense
("BMD") programs, and 16.2% in intelligence agency support accounted for 102.1%
of the revenue increase in 1999. A net decrease in revenues of 2.1% was realized
in other customer business areas, which included Ballistic Missile Defense
Organization ("BMDO"), Air Force, Navy, and commercial programs. The Company has
historically received most of its revenues from Department of Defense ("DOD")
programs. Non-DOD revenues represented 16.9%, 11.5% and 9.1% of total revenue in
1999, 1998, and 1997, respectively. Prior to 1996, support of the BMD program
was the Company's primary source of DOD revenue. Starting in 1997 and continuing
through 1999, non-BMD DOD programs have been 11.4%, 10.0% and 11.5% higher than
revenues in BMD DOD Programs in 1999, 1998, and 1997, respectively. As in the
prior year, again in 1999 technical services, engineering, and field services
represented the Company's largest growth area. Specifically, technical service
revenue increased 68% over 1998 and grew to 17% of total revenue.

      In the past, the Company's backlog has generally been indicative of its
future revenues. The end of the year annualized contract backlog, representing
expected sales on existing contracts for the coming year, increased from
$104,700,000 in 1998 to $116,200,000 in 1999, an increase of 11.0%. Annual sales
as a percent of year-end annualized contract backlog were 110.0%, 104.8% and
111.9% in 1999, 1998, and 1997, respectively. Although the Company's backlog has
been indicative of its future revenues, there can be no assurance that this will
continue. The Company's backlog is typically subject to variations from year to
year as contracts are completed, major existing contracts are renewed, or major
new contracts are awarded. Additionally, all U.S. government contracts included
in backlog, whether or not funded, may be terminated at the convenience of the
U.S. government.

     The Company's primary business strategy over the last five years has been
to establish a new foundation for future growth in recognition of the decline of
the DOD market for its traditional engineering business. To implement this
strategy, the Company restructured in 1996 into three sectors. Each focuses on
one of three core



                                       13
<PAGE>   16

business areas: (1) system engineering for defense and space systems; (2)
information systems engineering, services, and products; and (3) engineering
services, development, and products for hardware technologies. Each operation
has significant autonomy in conducting business. The organizational structure
continued for 1999.

      At the start of each year the Company establishes specific financial
objectives for each of its sectors and operations. The Company also annually
establishes specific corporate business objectives. For 1999, the corporate
business objectives included (i) begin generating significant revenues from
product lines, (ii) increase proposal and opportunity backlog focused on new
customers, and (iii) development of current and future managers. The Company met
its 1999 financial plan in almost all respects. Each of the sectors achieved
increases in sales, gross profit, net profit, and contract backlog. In the area
of corporate business objectives, the Company was unsuccessful in achieving any
significant income on any of its product lines. The three product lines are
SecurECTM, an application of end-to-end security software to commercial
Electronic Data Interchange ("EDI") on the Internet; nanAlignTM, an
electro-optic system to compensate for air turbulence error sources in the
manufacture of integrated circuits and flat panel displays; and ZeusTM, a mobile
mounted laser system to neutralize mines and unexploded ordnance on test ranges.
Progress was made toward the objective for both the ZeusTM and nanAlignTM
product lines and both will continue to be pursued in 2000. Based on the modest
sales of the SecurECTM product, further investment in the product line was
suspended and plans are being developed for the future disposition of the
technology.

     Stockholders' equity increased 17.2% during 1999. The Company currently
commits 50% of its net after tax profits plus the net proceeds from stock
transactions to repurchase stock from stockholders. The Company's major
components of debt (deferred income taxes, balance of promissory notes issued to
repurchase stock, and working capital financing) decreased by approximately
4.8%, to $4,570,000 in 1999 from $4,800,000 in 1998. In 1999, the debt-to-equity
ratio achieved a new historical low of 0.4 versus 0.5 in 1998 and 0.8 for 1997.

Liquidity and Capital Resources

     The Company's primary source of funding its operations in 1999 was
self-funding from on-going business activities augmented by borrowings from its
bank line of credit. The bank line of credit provides for borrowings up to
$10,000,000 with all borrowings due July 2, 2001. The Company believes that, as
in the past, it will be able to renew its banking agreement under similar or
improved terms. Interest payments on borrowings under the line of credit were
$160,000 in 1999 compared to $271,000 in 1998. At the end of 1999, borrowings
for working capital were $951,000, down from $1,266,000 at the end of 1998. Days
sales outstanding ("DSO") in receivables averaged 80 days in 1999, down from an
average of 85 and 88 days in 1998 and 1997, respectively. Average monthly
borrowing was $1,926,000 in 1999, down from $3,256,000 in 1998. A decrease in
investment in product lines combined with a decrease in the DSO resulted in the
lower average borrowing. The Company anticipates that its existing capital
resources and access to the line of credit will be adequate for planned
operations for the foreseeable future.

     The Company continues to conduct its stock repurchase program on a
quarterly basis under which the Company repurchases shares of its stock desired
to be sold by existing stockholders (i.e., continuing employees, terminating
employees, and former employees). The amount of funds available for the
repurchase of stock is comprised of 50% of the net profits (based on a four
quarter moving average) plus all funds realized by the Company through operation
of its stock program. The two primary sources of stock funds are from the
exercise of options granted to employees and from the funding of its stock
related benefits programs. In periods of declining profits and decreasing stock
prices, the funds available for the repurchase of stock can be negatively
impacted. The repurchase of stock within the available quarterly funds is
prioritized first to the repayment of promissory notes previously issued to
repurchase stock, second to the repurchase of all or a portion of the stock of
terminating employees, third to all stockholders desiring to sell a minimum
amount (currently $3,000), and finally to all stockholders desiring to sell
stock on a pro rata basis relative to their respective stock ownership. Sale of
stock on a pro rata basis is held quarterly. There is no other market for the
sale and purchase of the Company's stock.




                                       14

      From inception, it has been the Company's policy to limit its Common Stock
ownership to current employees by repurchasing all stock of terminating
employees with cash or promissory notes. However, a 40% reduction in the
Company's staff level starting mid-1993 and through 1994 resulted in the
termination of employees who held, in the aggregate, approximately 30% of the
Company's total Common Stock then outstanding. Continued issuance of promissory
notes to repurchase the stock of terminating employees jeopardized the bank
covenant on equity for the bank line of credit. Consequently, the Company
suspended the policy of repurchasing stock with promissory notes from
terminating employees in April of 1994 and terminated the repurchase of any
stock of terminating employees with quarterly repurchase funds in April of 1995.
The outstanding promissory note balance for prior years' stock repurchases
declined from $4,224,000 at the end of 1994 to $1,232,000 at the end of 1999. As
the Company's profit growth improved and debt service on notes declined, and as
employee confidence in future stock growth returned, as demonstrated by the
exercise of options, the liquidity of the stock returned to pre-1993 levels in
1996 and continued through 1999. In 1996, the Company resumed partial cash
repurchases of stock from terminating employees, but did not resume the issuance
of promissory notes. In 1997, the Board of Directors gave the Plan Administrator
the authority to issue new promissory notes, at his discretion, in order to
resume the policy of repurchasing all stock of terminating employees. In 1998
and 1999, the Company repurchased all stock of terminating employees and issued
one new promissory note with a value of $195,000 and eight new promissory notes
with a value of $1,114,000, respectively. The amount of stock held by former
employees decreased from 4.9% (305,700 shares) at the end of 1998 to 4.8%
(291,136 shares) at the end of 1999.

     Under the Stock Purchase Agreement, which the Company entered into with
SAIC in November 1994, SAIC purchased a total of $2,400,000 of Company Preferred
Stock in 1994, 1995, and 1996. The Company began quarterly repurchase of SAIC
Preferred Stock starting with the May 21, 1999 quarterly trade with funds
available within the stock repurchase limitation. Additional Preferred Stock was
repurchased from SAIC in the August 21,1999 quarterly trade out. During 1999,
the Company redeemed a total of 121,661 preferred shares from SAIC for
$1,302,000.

Capital Commitments

     Commitments for capital expenditures were not material at January 2, 2000.

Effects of Inflation

     The majority of the Company's contracts is cost reimbursement type
contracts or is completed within one year. As a result, the Company has been
able to anticipate increases in costs when pricing its contracts. Bids for
longer-term fixed-price and time-and-materials type contracts typically include
labor and other cost escalation in amounts expected to be sufficient to cover
cost increases over the period of performance. Consequently, while costs and
revenues include an inflationary increase commensurate with the general economy,
the effects of inflation have not significantly impacted net income as a
percentage of revenues.

ITEM 7a.          QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

for the grant of stock options, stock bonuses or rights to purchase up to an
aggregate of 14,000,000 shares of the Company's authorized but unissued Common
Stock (subject to adjustment in the event of stock dividends, stock splits,

Stock Option Plan.

administers the Stock Plan. However, the Board of Directors may at any time
designate another officer or other employee of the Company, the Board itself, or
a committee thereof, to act as administrator of the Stock Plan. Subject to the
express provisions of the Stock Plan, the Administrator has full authority to
interpret the Stock Plan and to make all other determinations necessary or
advisable for the administration of the Stock Plan.

      All shares issued under the Stock Plan are subject to restrictions on
transferability and the right of the Company to repurchase the shares upon the
termination of the stockholder's association with the Company. These transfer
restrictions and repurchase rights are set forth both in the Stock Plan and in
the Company's Certificate of Incorporation.

      During fiscal 1999, options covering a total of 599,015 shares were
granted under the Stock Plan to a total of 784 employees of the Company. The

      Profit Sharing Plan. The Company has adopted and maintains a defined
contribution Profit Sharing Plan, which provides tax-qualified retirement
benefits to participating employees. All of the Company's employees are eligible
to participate in Company contributions to the Profit Sharing Plan, except those
employees in the Technical Services ("TS") business unit.

      The Board of Directors determines the amount of the Company's annual
contribution to the Profit Sharing Plan, in its discretion. The Company has
established a target contribution that represents the amount the Company will
contribute if the Company's actual operating results meet certain guidelines.
The target contribution anticipates a contribution equal to the sum of (a) 15%
of the compensation paid to participants who have completed two years of
employment with the Company, (b) 10% of the compensation paid to participants
who have completed at least one but not more than two years of employment with
the Company, and (c) 5% of the compensation paid to participants who have
completed less than one year. All contributions are subject to at least 1000
hours of service during the year with the Company. If the full target
contribution is made by the Company for any given year, each eligible
participant in the Profit Sharing Plan for that year receives an allocation to
his or her account equal to the percentage of such participant's compensation
indicated above based on the participant's length of service with the Company,
subject to limitations on the maximum amount of such contribution imposed by the
Employee Retirement Income Security Act of 1974 ("ERISA"). If the full target
contribution is not made by the Company for any given year, the Company's
contribution is allocated among the eligible participants based on their
relative compensation for the year, subject to any limitations imposed by ERISA,
and provided, however, that the allocation to each participant will not exceed
the percentage of such participant's compensation indicated above based on the
length of the participant's service with the Company. Up to 50% of the Company's
annual contribution may be made in the form of shares of the Company's Common
Stock. Employees may elect to have a larger than 50% share paid in the form of
Company stock.

     Employees in the Company's Technical Services ("TS") business unit are not
eligible to receive Company contributions to their Profit Sharing Plan accounts
as described above. TS employees may, however, elect to defer a portion of their
compensation into their accounts, up to the limits set by the Internal Revenue
Service,


                                       20

and the Company matches up to 20% of their deferrals in the form of fully vested
SPARTA Common Stock. Employees other than those in the TS business unit may also
elect to defer a portion of their compensation into their accounts in the Profit
Sharing Plan, but the Company does not match their contributions.

     Mary Frances Winton, Corporate Director of Special Projects, serves as
Special Trustee of the Profit Sharing Plan, and in that capacity is the record
holder of the Company's Common Stock allocated to employees' accounts in the
Profit Sharing Plan.

Director Compensation

      Directors who are not employees of the Company, one of its subsidiaries,
or SAIC, receive fees of $2,200 per day for each Board meeting or committee
meeting which they attend. In addition, each director who is not an employee at
the Company's fiscal year-end received stock options based upon earnings of the
Company for the year. Non-employee directors that chair Board committees are
awarded additional options. During 1999, 3,150 stock options were awarded to
outside directors. The options can be exercised one year after they are awarded
and vest one year to three years from the date of grant and expire in four
years.

                        REPORT OF INDEPENDENT ACCOUNTANTS





To the Board of Directors and Stockholders of SPARTA, Inc.

In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) on page 23, present fairly, in all material
respects, the financial position of SPARTA, Inc. and its subsidiary at December
31, 1999 and 1998, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1999 in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

A)   DESCRIPTION OF BUSINESS - SPARTA, Inc. (The "Company"), is essentially
     employee-owned and primarily engaged in the design and analysis of systems
     for national defense programs and commercial applications of defense
     technology.

B)   PRINCIPLES OF CONSOLIDATION - The consolidated financial statements include
     the accounts of SPARTA, Inc. and its wholly owned subsidiary. All
     significant intercompany transactions and accounts have been eliminated in
     consolidation.

C)   USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS. - The preparation
     of financial statements in conformity with generally accepted accounting
     principles requires management to make estimates and assumptions that
     affect (1) the reported amounts of assets and liabilities, (2) disclosure
     of contingent assets and liabilities, and (3) the reported amounts of
     revenues and expenses. Actual results could differ from those estimates.

D)   FISCAL YEAR - The Company's fiscal year is the 52 or 53 week period ending
     on the Sunday closest to December 31. However, in 1997 the fiscal year
     ended on the Friday closest to December 31. The Company's last three fiscal
     years ended on January 2, 2000, January 3, 1999, and January 2, 1998;
     however, for ease of presentation of the financial statements, the year
     ends have been presented as December 31, 1999, 1998 and 1997.

E)   SALES - Sales are primarily recorded using the percentage of completion
     method and are based on contract costs incurred to date compared with total
     estimated costs at completion. To the extent costs at completion are
     estimated to exceed contract price, charges are made to current earnings in
     the period in which this is first determined. Sales for the years ended
     December 31, 1999, 1998 and 1997, were primarily generated through direct
     or indirect sales to U.S. government agencies.

F)   EQUIPMENT AND IMPROVEMENTS - Property and equipment are recorded at cost
     and are depreciated or amortized using the straight-line method over the
     shorter of estimated useful lives or lease periods, ranging from 5 to 15
     years.

G)   INCOME TAXES - The Company accounts for income taxes under Statement of
     Financial Accounting Standards No. 109 (FAS 109), "Accounting for Income
     Taxes," which requires the recognition of deferred tax liabilities and
     assets for expected future tax consequences of temporary differences
     between the financial statement and tax basis of assets and liabilities at
     the applicable enacted tax rates.

H)   STATEMENT OF CASH FLOWS - For the purpose of the statement of cash flows,
     the Company considers all highly liquid debt instruments purchased with an
     original maturity of three months or less to be cash equivalents.
     Repurchases of common stock included issuances of notes payable of
     $1,114,000, $195,000 and $43,000 for the years ended December 31, 1999,
     1998 and 1997, respectively.

I)   REDEEMABLE PREFERRED STOCK - The Company's redeemable preferred stockholder
     has the option to require the Company to repurchase all of the preferred
     shares (the "Put") at the common stock formula price as further discussed
     below. Redeemable preferred stock activity for the periods indicated are as
     follows:

</TABLE>

     The Put may be exercised by the stockholder by written notice provided,
     however, that the Put may not be exercised as to less than all of the
     shares then owned by the shareholder. The Put terminates on November 18,
     2004.

     In the event of any liquidation, dissolution or winding up of the
     Corporation, whether voluntary or involuntary, the holders of preferred
     stock then outstanding shall be entitled to a liquidation preference out of
     the assets of the Company before any payment is made to common
     stockholders. The liquidation preference is the amount equal to the
     weighted average price per share paid to the Company upon the original
     issuance of all preferred shares outstanding as of the date of liquidation.
     The holders of preferred stock shall not have voting rights to vote on the
     election of Directors or to vote on any other matter which may be the
     subject of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     stockholder action. Each share of redeemable preferred stock is
     automatically convertible into one share of the Company's common stock upon
     the closing of the first underwritten public offering by the Company or in
     the event of any merger or consolidation of the Company with or into any
     other entity in which the Company is not the surviving corporation.

     The preferred stockholder and the Company have entered into various
     subcontract agreements whereby the preferred stockholder subcontracts to
     the Company and vice versa. Amounts paid by the Company under such
     agreements were $6,740,000, $5,327,000 and $4,988,000 for the years ended
     1999, 1998 and 1997, respectively. The amounts received under such
     agreements were $86,000, $396,000 and $1,246,000 for the years ended
     December 31, 1999, 1998 and 1997, respectively. At December 31, 1999, the
     Company's accounts payable to and accounts receivable balances from the
     preferred stockholder were $1,033,000 and $62,000, respectively.

J)   TREASURY STOCK - Treasury stock is shown at cost, and at December 31, 1999,
     1998 and 1997, consisted of 0, 8,256,847 and 7,541,820 shares,
     respectively, of common stock. During December 1999, all treasury shares
     outstanding, a total of 8,972,291 common shares, were retired.

     Repurchases of outstanding stock by the Company in exercise of its right of
     repurchase upon termination of employment (as defined) are made on a
     formula basis. The stock price is recalculated quarterly by management
     using a formula approved by the Board of Directors. The Company's stock
     price is evaluated bi-annually by an independent valuation firm. Formula
     stock prices at valuation dates are as follows:

K)   EARNINGS PER SHARE (EPS) - During 1997, the Company adopted Statement of
     Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share." All
     earnings per share amounts presented for prior years have been restated in
     accordance with SFAS No. 128.

     Basic earnings per share is computed based on the weighted-average number
     of common shares outstanding during the respective years. Diluted earnings
     per share include the dilutive effects of stock options and shares granted
     under the restricted stock compensation plan. Accretion is deducted from
     net income available to common stockholders in computing both basic and
     diluted earnings per share. Because the impact would have been
     antidilutive, stock options with an exercise price above fair market value
     totaling 58,235 shares for 1997 were not included in the calculation of
     diluted earnings per share.

     A reconciliation of the numerators and denominators for the basic and
     diluted earnings per share computations are shown below:

L)   DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying
     amounts of cash and cash equivalents, accounts receivable, accounts
     payable, and accrued liabilities approximate fair value because of the
     short maturity of those instruments. The carrying value of the Company's
     notes payable approximates fair value based upon current rates offered to
     the Company for obligations with similar remaining maturities.

M)   ACCOUNTING FOR STOCK-BASED COMPENSATION - The Company accounts for employee
     stock based compensation in accordance with Accounting Principles Board
     Opinion No. 25 and related interpretations. The disclosures required by
     Statement of Financial Accounting Standards No. 123, "Accounting for
     Stock-Based Compensation" ("SFAS 123"), have been included in Note 9.

N)   NEW ACCOUNTING STANDARDS - In June 1998 the Financial Accounting Standards
     Board issued Statement of Financial Accounting Standard No. 133; Accounting
     for Derivative Instruments and Hedging Activities ("SFAS 133"). SFAS No.
     133 is required to be adopted in fiscal years beginning after June 15, 2000
     and establishes accounting and reporting standards for derivative
     instruments and for hedging activities. The Company does not anticipate
     that the adoption of SFAS 133 will have a material impact on its financial
     position or results of operations.

NOTE 2 - ACCOUNTS RECEIVABLE

Accounts receivable is comprised of the following:

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

The Company has a concentration of its receivables with U.S. Government agencies
or companies who perform work for U.S. Government agencies. The Company believes
that the credit risk associated with these receivables is minimal.

Unbilled receivables consist primarily of revenues recognized on government
contracts for which billings have not yet been presented. Contract costs for
certain contracts, including applicable indirect costs, are subject to audit and
adjustment by negotiations between the Company and U.S. Government
representatives. Revenues for such contracts have been recorded in amounts that
are expected to be realized on final settlement.

Claimed costs associated with terminated contracts, costs incurred in advance of
contract funding and estimated award fees, included in unbilled accounts
receivable, amounted to $2,470,000 and $2,566,000 at December 31, 1999 and 1998,
respectively. These amounts may not be fully recoverable; however, the Company
does not expect to sustain losses of any significant consequence with respect to
such costs.

At December 31, 1999, the bank line of credit provided borrowings up to $10.0
million with all borrowings due July 2, 2001. The line of credit agreement
prohibits the payment of dividends by the Company without the bank's prior
consent and requires the Company to maintain certain financial ratios. The
Company was in compliance with such requirements at December 31, 1999.

At December 31, 1999 and 1998, the Company had 11 and 6, respectively,
outstanding unsecured notes payable arising from repurchases of the Company's
stock that are subordinated to the bank. The following notes payable accrue
interest at the lesser of the bank's prime rate, the Federal Reserve discount
rate (5.0% at December 31, 1999) or 10%.

</TABLE>

The Company has an arrangement with a bank to allow stockholders to borrow up to
$250,000 for Company stock purchases. The bank borrowings are collateralized by
the stock. Total collateralized borrowings for all outstanding loans cannot
exceed $500,000. In the event of default, the Company has agreed to purchase the
stock back from the bank for an amount equal to the outstanding principal and
accrued interest. At December 31, 1999 and 1998, $24,000 and $34,000,
respectively, in loans were outstanding under this arrangement.

The Company is subject to certain legal proceedings and claims that arise in the
ordinary course of its business. In the opinion of management, based in part on
the opinion of counsel, the ultimate outcome of such matters will not have a
material impact on the Company's financial position or results of operations.
- ----------------------------

NOTE 9 - STOCK OPTIONS AND BENEFIT PLANS

The Company has a stock option plan that authorizes the granting of options to
employees and directors to purchase unissued common stock subject to certain
conditions, such as continued employment. Options are generally granted at the
current stock price of the Company's common stock at the date of grant, become
exercisable one year to three years from the date of grant, and expire in four
years. Changes during the years ended December 31, 1999, 1998 and 1997 under the
plan were as follows:

During the years ended December 31, 1999, 1998 and 1997, options on 536,604,
548,987 and 623,704 shares, respectively, were granted based primarily on
employee success at obtaining new and follow-on business during the year. Prior
to 1991, the number of options earned was based primarily on a formula tied to
an annualized funded value of contract awards. In 1991 and thereafter, options
are earned primarily based on a formula tied to financial recorded gross profit.
Approximately 11% of all option grants are given to new hires and staff based
upon performance as determined at the discretion of management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS





The Company accounts for its stock option plan pursuant to APB Opinion No. 25.
Had compensation expense for these plans been determined consistent with SFAS
123, the Company's net income and net income per share would have been reduced
to the pro forma amounts in the following table. Because the SFAS 123 method of
accounting has not been applied to options prior to December 31, 1994, the
resulting pro forma compensation costs may not be representative of costs to be
expected in future years.

The fair value of each option is estimated at the time of grant as its minimum
value, which is calculated by subtracting the present value of the option
exercise price over the expected option term from the stock price at the date of
grant. Present values were calculated using weighted average risk free interest
rates of 6.0%, 5.5% and 6.5% for 1999, 1998 and 1997 respectively, and a
weighted-average expected life of 4 years. The weighted-average fair value of
options granted during 1999, 1998 and 1997 was $2.31, $1.76 and $1.24,
respectively.

At December 31, 1999, 1998 and 1997 there were options outstanding at prices
ranging from $4.53 to $11.86, $3.91 to $9.15 and $3.91 to $6.90, respectively,
with expiration dates through 2003. Of the options outstanding at December 31,
1999, 1998 and 1997, options to purchase 451,696, 563,483 and 518,132 shares,
respectively, were immediately exercisable at prices ranging from $4.53 to
$11.86, $3.91 to $9.15 and $3.84 to $6.90, per share, respectively.

As of December 31, 1999, 1998 and 1997, 9,065,245, 9,664,260 and 10,282,766
shares, respectively, were reserved for future issuances under the stock option
plan.

The Company offers eligible employees in its Technical Services and Tactical
Systems Division the option to contribute to a deferred compensation 401(k)
plan. Prior to 1991, the Company made no contributions to the plan. In 1991 and
thereafter, the Company made a matching contribution of Company stock of 20% of
the employee contributions. For the years ended December 31, 1999, 1998 and
1997, 10,751, 11,216 and 9,052 shares, totaling $117,000, $93,000 and $60,000
respectively, were contributed to the plan

The Company also sponsors a restricted stock compensation plan designed to
provide long-term incentive to key employees by making deferred awards of SPARTA
stock which become fully vested after a five year period. Shares are forfeited
if the participant leaves the Company prior to vesting. During 1999, 18,537
shares of restricted stock were granted at a price of $9.71 per share. During
1998, 22,106 shares of restricted stock were granted at a price of $7.69 per
share. During 1997, 25,294 shares of restricted stock were granted at a price of
$5.93 per share and 8,583 shares previously granted at a price of $4.66 per
share were retired. Compensation expense of $117,000, $81,000 and $48,000 was
recognized in 1999, 1998 and 1997, respectively.

The Company pays a portion of annual bonuses in the form of stock. For the years
ended December 31, 1999, 1998 and 1997, 54,974, 65,363 and 110,340 shares
totaling $690,000, $635,000 and $856,000 respectively were issued under the
plan.

The Company has a defined contribution retirement plan for all eligible
employees except employees in the Technical Systems Division. The Company's
contributions for this plan for the years ended December 31, 1999, 1998 and 1997
were $4,291,000, $3,821,000 and $3,055,000 respectively. A portion of the
contributions to the plan were in the form of common stock. For the years ended
December 31, 1999, 1998 and 1997, 198,933, 236,080 and 232,620 shares, totaling
$2,127,000, $1,927,000 and $1,492,000 respectively, were contributed to the
plan.

[LOGO] UNION BANK OF CALIFORNIA


                                 LOAN AGREEMENT

         THIS LOAN AGREEMENT ("AGREEMENT") is made and entered into as of
7/2/1999, by and between Sparta, Inc., a Delaware corporation ("Borrower"), and
UNION BANK OF CALIFORNIA, N.A. ("Bank"). This Agreement supercedes and replaces
that certain Fourth Amended and Restated Loan Agreement dated August 3, 1995, as
amended.

       SECTION 1. THE LOAN

                   1.1 THE REVOLVING LOAN. Bank will loan to Borrower an amount
not to exceed Ten Million Dollars ($10,000,000) outstanding in the aggregate at
any one time (the "Revolving Loan"). Borrower may borrow, repay and reborrow all
or part of the Revolving Loan in accordance with the terms of the Revolving
Note. All borrowings of the Revolving Loan must be made before July 2, 2001 at
which time all unpaid principal and interest of the Revolving Loan shall be due
and payable. The Revolving Loan shall be evidenced by a promissory note (the
"Revolving Note") on the standard form used by Bank for commercial loans. Bank
shall enter each amount borrowed and repaid in Bank's records and such entries
shall be deemed to be the amount of the Revolving Loan outstanding. Omission of
Bank to make any such entries shall not discharge Borrower of its obligation to
repay in full with interest all amounts borrowed.

                  1.2 TERMINOLOGY.

                      As used herein the word "Loan" shall mean, collectively,
all the credit facilities described above.

                      As used herein the word "Note" shall mean, collectively,
all the promissory notes described above.

                      As used herein, the words "Loan Documents" shall mean all
documents executed in connection with this Agreement.

                  1.3 PURPOSE OF LOAN. The proceeds of the Revolving Loan shall
be used for working capital and general corporate purposes.

                  1.4 INTEREST. The unpaid principal balance of the Revolving
Loan shall bear interest at the rate or rates provided in the Revolving Note and
selected by Borrower. The Revolving Loan may be prepaid in full or in part only
in accordance with the terms of the Revolving Note and any such prepayment shall
be subject to the prepayment fee provided for therein.

                  1.5 UNUSED COMMITMENT FEE. Commencing on March 31, 2000 and on
the last calendar day of each three month period thereafter, or the earlier
termination of the Loan, Borrower shall pay to Bank a fee of one eighth of one
percent (.125%) per year on the average unused portion of the Loan for the
preceding quarter computed on the basis of actual days elapsed of a year of 360
days. For the period commencing December 1, 1999 through December 31, 1999,
Borrower shall pay the aforementioned fee prorated for such period.


<PAGE>   2


                  1.6 BALANCES. Borrower shall maintain its major depository
accounts with Bank until the Note and all sums payable pursuant to this
Agreement have been paid in full.

                  1.7 DISBURSEMENT. Upon execution hereof, Bank shall disburse
the proceeds of the Loan as provided in Bank's standard form Authorization
executed by Borrower.

                  1.8 SECURITY. Prior to any disbursement of the Loan, Borrower
shall have executed a security agreement, on Bank's standard form, and a
financing statement, suitable for filing in the office of the Secretary of State
of the State of California and any other state designated by Bank, granting to
Bank a first priority security interest in such of Borrower's property as is
described in said security agreement. Exceptions to Bank's first priority, if
any, are permitted only as otherwise provided in this Agreement. At Bank's
request, Borrower will also obtain executed landlord's and mortgagee's waivers
on Bank's form covering all of Borrower's property located on leased or
encumbered real property.

                  1.9 CONTROLLING DOCUMENT. In the event of any inconsistency
between the terms of this Agreement and any Note or any of the other Loan
Documents, the terms of such Note or other Loan Documents will prevail over the
terms of this Agreement.

         SECTION 2. CONDITIONS PRECEDENT

         Bank shall not be obligated to disburse all or any portion of the
proceeds of the Loan unless at or prior to the time for the making of such
disbursement, the following conditions have been fulfilled to Bank's
satisfaction:

                  2.1 COMPLIANCE. Borrower shall have performed and complied
with all terms and conditions required by this Agreement to be performed or
complied with by it prior to or at the date of the making of such disbursement
and shall have executed and delivered to Bank the Note and other documents
deemed necessary by Bank.

                  2.2 BORROWING RESOLUTION. Borrower shall have provided Bank

pursuant to this Agreement.

                  2.3 CONTINUING COMPLIANCE. At the time any disbursement is to
be made, there shall not exist any event, condition or act which constitutes an
event of default under Section 6 hereof or any event, condition or act which
with notice, lapse of time or both would constitute such event of default; nor
shall there be any such event, condition, or act immediately after the
disbursement were it to be made.

         SECTION 3. REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants that:

                  3.1 BUSINESS ACTIVITY. The principal business of Borrower is

                                      -2-

<PAGE>   3


                  3.2 AFFILIATES AND SUBSIDIARIES. Borrower's affiliates and
subsidiaries (those entities in which Borrower has either a controlling interest
or at least a 25% ownership interest) and their addresses, and the names of
Borrower's principal shareholders, are as provided on a schedule delivered to
Bank on or before the date of this Agreement.

                  3.3 AUTHORITY TO BORROW. The execution, delivery and
performance of this Agreement, the Note and all other agreements and instruments
required by Bank in connection with the Loan are not in contravention of any of
the terms of any indenture, agreement or undertaking to which Borrower is a
party or by which it or any of its property is bound or affected.

                  3.4 FINANCIAL STATEMENTS. The financial statements of
Borrower, including both a balance sheet at December 31, 1998, together with
supporting schedules, and an income statement for the twelve (12) months ended
December 31, 1998 have heretofore been furnished to Bank, and are true and
complete and fairly represent the financial condition of Borrower during the
period covered thereby. Since December 31, 1998, there has been no material
adverse change in the financial condition or operations of Borrower.

                  3.5 TITLE. Except for assets which may have been disposed of
in the ordinary course of business, Borrower has good and marketable title to
all of the property reflected in its financial statements delivered to Bank and
to all property acquired by Borrower since the date of said financial
statements, free and clear of all liens, encumbrances, security interests and
adverse claims except those specifically referred to in said financial
statements.

                  3.6 LITIGATION. There is no litigation or proceeding pending
or threatened against Borrower or any of its property which is reasonably likely
to affect the financial condition, property or business of Borrower in a
materially adverse manner or result in liability in excess of Borrower's
insurance coverage.

                  3.7 DEFAULT. Borrower is not now in default in the payment of
any of its material obligations, and there exists no event, condition or act
which constitutes an event of default under Section 6 hereof and no condition,
event or act which with notice or lapse of time, or both, would constitute an
event of default.

                  3.8 ORGANIZATION. Borrower is duly organized and existing
under the laws of the state of its organization, and has the power and authority
to carry on the business in which it is engaged and/or proposes to engage.

                  3.9 POWER. Borrower has the power and authority to enter into
this Agreement and to execute and deliver the Note and all of the other Loan
Documents.

                  3.10 AUTHORIZATION. This Agreement and all things required by
this Agreement have been duly authorized by all requisite action of Borrower.

                  3.11  QUALIFICATION. Borrower is duly qualified and in good
standing in any jurisdiction where such qualification is required.

                  3.12  COMPLIANCE WITH LAWS. Borrower is not in violation with
respect to any applicable laws, rules, ordinances or regulations which
materially affect the operations or financial condition of Borrower.

                  3.13 ERISA. Any defined benefit pension plans as defined in
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), of
Borrower meet, as of the date hereof, the minimum funding standards of Section
302 of ERISA, and


                                      -3-



<PAGE>   4


no Reportable Event or Prohibited Transaction as defined in ERISA has occurred
with respect to any such plan.

                  3.14 REGULATION U. No action has been taken or is currently
planned by Borrower, or any agent acting on its behalf, which would cause this
Agreement or the Note to violate Regulation U or any other regulation of the
Board of Governors of the Federal Reserve System or to violate the Securities
and Exchange Act of 1934, in each case as in effect now or as the same may
hereafter be in effect. Borrower is not engaged in the business of extending
credit for the purpose of purchasing or carrying margin stock as one of its
important activities and none of the proceeds of the Loan will be used directly
or indirectly for such purpose.

                  3.15 CONTINUING REPRESENTATIONS. These representations shall
be considered to have been made again at and as of the date of each disbursement
of the Loan and shall be true and correct as of such date or dates.

         SECTION 4. AFFIRMATIVE COVENANTS

         Until the Note and all sums payable pursuant to this Agreement or any
other of the Loan Documents have been paid in full, unless Bank waives
compliance in writing, Borrower agrees that:

                  4.1 USE OF PROCEEDS. Borrower will use the proceeds of the
Loan only as provided in subsection 1.3 above.

                  4.2 PAYMENT OF OBLIGATIONS. Borrower will pay and discharge
promptly all taxes, assessments and other governmental charges and claims levied
or imposed upon it or its property, or any part thereof, provided, however, that
Borrower shall have the right in good faith to contest any such taxes,
assessments, charges or claims and, pending the outcome of such contest, to

manner or extend credit, except as allowed by Borrower's Stock Option Plan.

                  5.5 INVESTMENTS. Borrower will not purchase the debt or equity

Borrower from such former employees and other persons to exceed One Million
Dollars ($1,000,000) unless all such amounts in excess of One Million Dollars
($1,000,000) are subordinated to all obligations now or hereafter owed by
Borrower to Bank pursuant to subordination agreements on Bank's standard form.
Bank hereby acknowledges and agrees, however, that each of such subordination
agreements shall permit Borrower to make, and shall permit the payee of the
promissory note(s) subordinated thereby to receive, regularly scheduled payments
of principal and interest under such promissory note(s) so long as Borrower has
made each and every payment of principal and interest due and owing to Bank and
is not in default under any of its agreements with Bank.

         SECTION 6. EVENTS OF DEFAULT

         The occurrence of any of the following events ("Events of Default")
shall terminate any obligation on the part of Bank to make or continue the Loan
and automatically, unless otherwise provided under the Note, shall make all sums
of interest and principal and any other amounts owing under the Loan immediately
due and payable, without notice of default, presentment or demand for payment,
protest or notice of nonpayment or dishonor, or any other notices or demands:

                  6.1 Borrower shall default in the due and punctual payment of

and instruments required by Bank in connection therewith shall be governed by

                  7.5 SEVERABILITY. Should any one or more provisions of this
Agreement be determined to be illegal or unenforceable, all other provisions
nevertheless shall be effective. In the event of any conflict between the

Mr. Wayne Winton, PRESIDENT
SPARTA, INC.
23041 de La Carlota, Suite 325
Laguna Hills, CA 92653-1507

Dear Wayne:

This Letter Agreement ("Agreement") will confirm the availability until July 2,
2001 of a Guideline of Credit ("Guideline") in the amount of Five Hundred
Thousand Dollars ($500,000) by Union Bank of California, N. A. ("Bank") to
qualifying employees of Sparta, Inc. ("Borrowers"). Advances under this
Guideline ("Loans") made by Bank to Borrowers shall be for amounts not less than
Twenty Five Thousand Dollars ($25,000) nor greater than Two Hundred Fifty
Thousand Dollars ($250,000). At no time will Loans made to any single Borrower
exceed Two Hundred Fifty Thousand Dollars ($250,000) singly or in aggregate. The
aggregate amount of all loans to Borrowers as provided herein shall at no time
exceed Five Hundred Thousand Dollars ($500,000). These Loans shall be
collateralized by stock in Sparta, Inc. owned by individual Borrowers. Bank will
lend against 40% of the value of the stock offered as collateral.

Any stock pledged to Bank to secure any Loans shall serve solely as collateral
for the relevant Loans and Bank shall be obligated to relinquish said stock when
the Loans and any Interest accrued thereon have been repaid in full.

Loans made under the Guideline shall be payable in equal monthly installments
over a period to be selected by the Borrowers, but at a minimum of one year to a
maximum of five years. The loans shall bear interest at the following rates on
the following amounts:

         1. Loans of $25,000 to $200,000 at date of funding shall bear interest
         at the Bank's Reference Rate plus one and one-half percent (1.5%).

         2. Loans greater than $200,000 shall bear interest at the Bank's
         Reference Rate plus one percent (1%).

Reference Rate means the rate announced by Bank from time to time at its
Corporate Headquarters as its Reference Rate. The rate on the Loans shall vary
concurrently with any change in such rate plus the applicable margin.

Borrowers shall pay an upfront commitment fee of 'Two Hundred Fifty Dollars
($250) for each transaction. No portion of this fee shall be refundable.

<PAGE>   12



All financial information submitted by Borrowers to Bank is true and correct in
all respects upon submission insofar as may be necessary to give Bank a true and
accurate knowledge of the subject matter thereof.

Before Bank is obligated to make any advance, Bank must receive all of the
following, each of which must be in form and substance satisfactory to Bank:

Borrower shall have delivered to Bank the following:

         A personal financial statement completed by each Borrower along with a
signed tax return for the most recent tax year.

         The original executed Promissory Note ("Note(s)")

         Collateral in the form of Stock certificates in an amount sufficient to
secure any Loan(s).

         An original executed Alternative Dispute Resolution.

         Original, executed documentation that the Bank otherwise deems
necessary or desirable to support the Loans.

For each Loan, Sparta, Inc. ("Purchaser") shall execute a Put Agreement on
Bank's form whereby Sparta shall agree that in the event of default ("Events of
Default") by any Borrowers, Sparta, Inc. will repurchase the defaulted
indebtedness for the total principal and interest outstanding.

The occurrence of any of the following events ("Events of Default") in relation
to any individual Loans made under the Guideline shall result in a Loan in
default and shall automatically activate the Put Agreement between Bank and
Sparta, Inc. and all defaulted Loans shall be governed by the terms of the Put
Agreement.

         Borrowers shall default in the due and punctual payment of the
         principal of or the interest on the Notes, or

         Borrowers are in default in any of the terms and conditions of any
         documentation supporting the Loans; or

         Any representation of warranty made by Borrowers herein or in any
         certificate of financial or other statement heretofore or hereafter
         furnished by Borrowers shall prove to be in any material respect false
         and misleading;

         Borrowers' failure to pay debts as they come due; or the filing by a
         Borrower or Purchaser of any petition under the bankruptcy,
         reorganizations, arrangement, insolvency, or other debtor's relief
         laws, or the filing against any Borrowers or Purchaser of any such
         petition or the appointment of a receiver, trustee or liquidation of
         all or a substantial part of Borrower's or Purchaser's assets if the
         filing against Borrower or Purchaser is not dismissed within thirty
         (30) days thereafter;

         Purchaser shall commit or do, or fail to commit or do, any act or thing
         which would constitute an event of default under any of the terms of
         any other agreement, document or instrument


<PAGE>   13


         executed, or to be executed by it and concerning a financial obligation
         of Purchaser, and such default shall not have been cured within any
         applicable period of grace provided in the agreement, document or
         instrument.

         All, or such as in the opinion of Bank constitutes substantially all,
         of the property of Borrower or Purchaser shall be condemned, seized or
         appropriated.

All loans made under the Guideline shall be evidenced by Bank's standard form of
documentation and the terms and conditions of this Agreement are supplemental to
such documentation. However, in the event of any conflict between the terms of
any of the documents and this Agreement, the terms of the documents shall
prevail.

If you agree to accept the terms of this Agreement, please sign the enclosed
acknowledgement copy and return it on or before September 10, 1999.
