ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS
- --------------------------------------------- 

On November 16, 1998, CACI International Inc announced that it has completed 
its acquisition of all of the common stock of QuesTech, Inc., which became 
effective at 11:59 p.m. on November 13, 1998.  The total consideration paid by 
CACI, including the assumption of liabilities, was approximately $42 million; 
QuesTech shareholders will receive $18.13 per share in cash as they surrender 
their Common Stock.  QuesTech specializes in the development and application 
of information technology and engineering services for the defense and 
national security community.  The transaction was funded through borrowings 
under CACI's existing line of credit with a group of banks.

QuesTech, which has over 600 employees worldwide, will be operated as a 
wholly-owned subsidiary of CACI under the new name CACI Technologies, Inc.  
The operations of the new subsidiary will be fully integrated into CACI to 
achieve the full benefit of the merger for customers and shareholders.  CACI 
expects the acquisition to be accretive to net earnings.  In its last full 
year of operations, QuesTech reported revenues of $78 million.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS

(a)(1) FINANCIAL STATEMENTS.  Restated consolidated financial statements for 
QuesTech, Inc. for the fiscal years ended December 31, 1997, 1996 and 1995, 
and Report of Independent Certified Public Accountants.

(b)(2) PRO FORMA FINANCIAL INFORMATION.  Pro forma financial information 
relative to the acquisition of QuesTech, Inc. for the most recent fiscal year 
ended June 30, 1998, and for the quarter ended September 30, 1998.

       The following CACI pro forma condensed consolidated statements of 
operations for the year ended June 30, 1998 and for the quarter ended 
September 30, 1998, and the CACI pro forma consolidated balance sheets as of 
June 30, 1998 and September 30, 1998, are unaudited and have been prepared on 
a pro forma basis to give effect to the acquisition (accounted for as a 
purchase) of QuesTech, Inc. as if the transaction had occurred on July 1, 
1998.

       The pro forma condensed consolidated statement of operations for the 
year ended June 30, 1998 does not purport to represent what CACI's result of 
operations would actually have been had the transaction in fact occurred on 
the aforementioned date, or to project CACI's results of operations for any 
future periods.  The pro forma adjustments are based upon available 
information and upon certain assumptions that management believes are 
reasonable under the circumstances.

       The pro forma condensed consolidated financial statements should be 
read in conjunction with the historical financial statements of both CACI and 
QuesTech, including the notes thereto.

Report of Independent Certified Public Accountants

Stockholders
QuesTech, Inc., and Subsidiaries


We have audited the accompanying consolidated balance sheets of QuesTech, Inc. 
(a Virginia corporation), and Subsidiaries as of December 31, 1997 and 1996, 
and the related consolidated statements of earnings, stockholders' equity and 
cash flows for each of the three years in the period ended December 31, 1997. 
These financial statements are the responsibility of the Corporation's 
management. Our responsibility is to express an opinion on these financial 
statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of QuesTech, Inc., and 
Subsidiaries as of December 31, 1997 and 1996, and the results of their 
operations and their cash flows for each of the three years in the period 
ended December 31, 1997, in conformity with generally accepted accounting 
principles.

We have also audited Schedule II as of December 31, 1997, and for each of the 
three years in the period then ended. In our opinion, this schedule presents 
fairly the information required to be set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1997, 1996 and 1995


NOTE A - SUMMARY OF ACCOUNTING POLICIES

1.  Nature of Operations

The Company performs a broad range of high technology services for industry 
and agencies of the United States Department of Defense ("DOD") and the 
national security community. These services are provided through two business 
units, QuesTech Research Division ("QTRD") and QuesTech Service Company 
("QTSC"). Revenues from government contracts account for 99% of the Company's 
revenues. A third subsidiary, QuesTech Packaging, Inc. ("QTPI") was in the 
business of manufacturing plastic containers until operations were ceased on 
August 31, 1998 (see Note J).

2.  Use of Estimates in the 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 the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

3.  Principles of Consolidation

The accompanying financial statements include the accounts of the Company and 
its wholly-owned subsidiaries. All material intercompany transactions have 
been eliminated in consolidation.

4.  Income Recognition

The Company provides services, primarily for the United States Government, 
under three types of contracts: cost-reimbursement, fixed price and 
time-and-materials. Substantially all of the Company's revenue is derived from 
these contracts. Approximately 40% of the Company's consolidated revenues 
during each of the last three years was generated by a major contract with the 
Department of the Army. Income is recognized for cost-reimbursement and 
fixed-price type contracts using the percentage-of-completion method based on 
costs incurred; for time-and-materials contracts, income is based on 
contractually defined billing rates applied to services performed and
materials delivered. Anticipated losses on contracts are recognized as soon as 
they become known.

Certain of the Company's contracts include provisions permitting the 
government to withhold a defined amount or percentage of a contract price 
until certain conditions have been satisfactorily met. These conditions 
primarily relate to uncompleted indirect cost rate negotiations and 
substantial completion of contract performance. The inclusion of these amounts 
in income is consistent with the revenue recognition policy stated above. The 
inclusion of the retainages and costs subject to audit in income is consistent 
with common industry practice.

A portion of the Company's revenues related to performance on certain 
cost-reimbursement type contracts is subject to audit by the United States 
Defense Contract Audit Agency (DCAA). Such contract audits have been completed 
through December 31, 1995 for QTRD and December 31, 1991 for QTSC. DCAA audits 
of contract costs for the government contract segment of QTSC for fiscal years 
1992 through 1995 are expected to be completed during 1998. Contract revenue 
has been recorded in amounts that are expected to be realized upon final 
settlement.

The Company provides reserves for potentially unrecoverable contract costs and 
uncollectible accounts receivable based upon a periodic review by management 
of the status of DCAA incurred cost audits and the collectibility of accounts 
receivable. Increases or decreases in such reserves are recorded in "Other 
Operating Expenses" in the accompanying financial statements.

5.  Operating Expenses

Operating expenses presented in the accompanying statements of operations 
reflect the allocation of overhead and general and administrative expenses.

6.  Statement of Cash Flows

For purposes 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.

7.  Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate 
that value:

o   Cash and cash equivalents, accounts receivable, accounts payable, line
    of credit, and other accrued liabilities - The carrying amounts
    approximate fair value because of the short maturity of these
    instruments. The Company's receivables arise primarily in connection
    with its performance on government contracts and therefore have
    negligible credit risk.

o   Cash Values of Insurance Policies - The fair value is based on the cash
    values accumulated in these policies, net of borrowings. Surrender
    charges are not reflected in the fair value amount unless cash
    withdrawals or loans are made against these policies.

o   Letter of credit - The fair value is based on the estimated cost to
    terminate or otherwise settle these obligations with the counter-parties.


Following is a summary of the estimated fair value at December 31, 1997, of

the Company's financial instruments other than those on which the carrying 
amount approximates fair value.

                                            Carrying        Fair
                                             Amount         Value
                                           ----------     ---------- 

     Cash values of Insurance policies     $1,697,800     $1,697,800

     Letter of credit                              --     $  250,000

The letter of credit, which was outstanding at December 31, 1997 was released 
on February 5, 1998.

8.  Property, Plant and Equipment and Related Depreciation

Property, plant and equipment are recorded at cost. Cost includes expenditures 
for major improvements and replacements and the net amount of interest cost 
associated with significant capital additions. Construction in progress costs 
and specialized manufacturing equipment in service are stated at the lower of 
cost or fair value, based on expected future cash flows from the capital 
investment. During 1997 and 1996, interest cost associated with construction 
in progress was expensed due to immaterial amounts. The cost of properties 
held under capital leases is equal to the lower of the net present value of 
the minimum lease payments or the fair value of the leased property at the 
inception of the lease.

Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over their estimated service lives (generally 
five to ten years), using both the straight-line and declining-balance 
methods. Amortization of computer software developed for internal use is over 
five years, based on a double-declining balance method. Leasehold improvements 
are amortized over the lives of the respective leases or the service lives of 
the improvements, whichever is the shorter period. Amortization of capitalized 
leased assets is included with depreciation expense.

In accordance with SFAS 121, "Accounting for the Impairment of Long-lived 
Assets and for Long-lived Assets to be Disposed of," long-lived assets and 
certain intangibles, including goodwill, are reviewed for impairment whenever 
events or changes in circumstances indicate that the related carrying amount 
may not be recoverable. The Company has determined that no impairment loss 
need be recognized for applicable assets of continuing operations.

9.  Goodwill

The excess of the acquisition costs over the fair value of the net assets of 
the businesses acquired is being amortized on a straight-line basis over 
periods ranging from 19 to 20 years.

The Company regularly performs a reassessment of the continuing value of the
acquired goodwill associated with the acquisitions. To the extent that the
future cash flows based on the contracts' expected operating profits will 
exceed the carrying cost of the asset, an impairment loss is not recognized. 
Contract termination or non-renewal of the contract are events or changes in
circumstances that indicate that the carrying amount of the goodwill asset may 
not be recoverable, thereby requiring the recognition of an impairment loss at 
that time.
10.  Accounting for Postretirement Benefits

The Company applies the provisions of SFAS 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions," and has elected to recognize the 
transition obligation on a delayed recognition basis. The transition 
obligation represents the unfunded portion of the accrued postretirement 
benefit obligation (the "APBO") as of the transition date less any accrued 
postretirement benefit cost. The accrued postretirement benefit cost as of the 
balance sheet date reflects the net periodic cost attributed to the current 
year, net of benefit payments, plus the accrued amount as of the beginning of 
the year. The cost measurement principles and required disclosures of SFAS 106 
are applied separately to each identifiable postretirement benefit plan. The 
accrued postretirement benefit cost obligation is reported as an aggregate 
amount in the financial statements.

11.  Accounting for Post-Employment Benefits

The Company periodically re-evaluates its projected obligations under
post-employment agreements when the subject officers receive compensation
increases during their years of active employment. The projected cost of
additional compensation payable during the post-employment years is discounted 
at present value and charged to operations. Periodic increases in the balances 
due each of the officers also reflect the accrued interest on
the discounted cost of the liability.

12.  Accounting for Stock-based Compensation

As permitted by SFAS 123, "Accounting for Stock-based Compensation," the 
Company uses the intrinsic value based method, as prescribed by Opinion 25, 
that measures compensation cost only to the extent that the option price is 
lower than the quoted market price of the stock at the date of the award. Pro 
forma disclosures of net income, and earnings per share are presented in Note 
I as if the fair value based method of accounting defined in SFAS 123 had been 
applied.

13.  Earnings per share

In 1997 the Financial Accounting Standards Board issued Financial Accounting
Standards No. 128 (SFAS 128), "Earnings Per Share." This Statement replaces 
the presentation of primary EPS with a presentation of basic EPS. It also 
requires dual presentation of basic and diluted EPS on the face of the income 
statement for all entities with complex capital structures and requires a 
reconciliation of the numerator and denominator of the basic EPS computation 
to the numerator and denominator of the diluted EPS computation. Basic EPS 
excludes dilution and is computed by dividing income available to common 
stockholders by the weighted-average number of common shares outstanding for 
the period. Diluted EPS reflects the potential dilution that could occur if 
securities or other contracts to issue common stock were exercised or 
converted into common stock or resulted in the issuance of common stock that 
then shared in the earnings of the entity. Diluted EPS is computed similarly 
to fully diluted EPS pursuant to Opinion 15. In complying with the 
requirements of SFAS No. 128, the Company has restated all prior period EPS 
data.

For purposes of computing the diluted EPS, the Company has dilutive stock
options as share equivalents using the treasury stock method. At December 31,
1997 and 1996, the Company's Stock Employee Compensation Trust (SECT), held
176,131 shares. These SECT shares have been excluded from the base of the EPS
calculations since they have not been allocated to individuals.

15.  New Accounting Standards

Reporting Comprehensive Income

The Financial Accounting Standards Board recently issued Statement of 
Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive 
Income,"effective for fiscal years beginning after December 15, 1997. This 
Statement establishes standards for reporting and display of comprehensive 
income and its components (revenues, expenses, gains and losses) in a full set 
of general-purpose financial statements. This Statement requires that all 
items that are required to be recognized under accounting standards as 
components of comprehensive income be reported in a financial statement that 
is displayed with the same prominence as other financial statements. SFAS 130 
does not require a specific format for that financial statement but requires 
that an enterprise display an amount representing total comprehensive income 
for the period in that financial statement. The Statement requires that an 
enterprise classify items of other comprehensive income by their nature in a 
financial statement and display the accumulated balance of other comprehensive 
income separately from retained earnings and additional paid-in capital in the 
equity section of a statement of financial position. Reclassification of 
financial statements for earlier periods provided for comparative purposes is 
required. Currently, the Company has no other comprehensive income.

Disclosures about Segments of an Enterprise and Related Information

The Financial Accounting Standards Board recently issued Statement of 
Financial Accounting Standards No. 131 (SFAS 131), "Disclosures about Segments 
of an Enterprise and Related Information," effective for periods beginning 
after December 15, 1997. This Statement establishes standards for the way that 
public business enterprises report information about operating segments in 
annual financial statements and requires that those enterprises report 
selected information about operating segments in interim financial reports 
issued to shareholders. It also establishes standards for related disclosures 
about products and services, geographic areas, and major customers.

This Statement requires that a public business enterprise report financial and 
descriptive information about its reportable operating segments. Operating 
segments are components of an enterprise about which separate financial 
information is available that is evaluated regularly by the chief operating 
decision maker in deciding how to allocate resources and in assessing 
performance. Generally, financial information is required to be reported on 
the basis that it is used internally for evaluating segment performance and 
deciding how to allocate resources to segments. This Statement requires that a 
public business enterprise reports a measure of segment profit or loss, 
certain specific revenue and expense items, and segment assets and certain 
other related information; information about the
revenues derived from the enterprise's products or services (or groups of
similar products and services), about the countries in which the enterprise
earns revenues and holds assets, and about major customers regardless of 
whether that information is used in making operating decisions.

However, this Statement does not require an enterprise to report information
that is not prepared for internal use if reporting it would be impracticable.
The Company will comply with the disclosure requirements of SFAS 131 in fiscal 
year 1998.

NOTE C -  LINE OF CREDIT

At December 31, 1997, the Company's remaining available line of credit (LOC)
through First Union Bank (formerly Signet Bank of Virginia) was $2.1 million.
The underlying credit agreement permits borrowings up to $6.0 million. The
Company has the option of paying interest on the principal amount of the prime 
rate or at LIBOR (London Interbank Offered Rate) plus 2.70%. The Company's 
borrowing rate at December 31, 1997 was 8.5% which was the prime rate. All 
borrowings are secured by a first lien security interest in all receivable 
accounts, contract rights, chattel paper, instruments, general intangibles, 
equipment, inventory, and documents now owned and hereafter acquired by the 
Company. The Company was in compliance with various financial covenants, which 
require the maintenance of a maximum debt-to-net worth ratio of 5 to 1 and a 
minimum tangible net worth of $3.0 million.

In addition to its revolving credit agreement, the Company has at its disposal 
a $750,000 term loan facility which expires on March 31, 1998. As of December 
31, 1997, the Company had not borrowed any amounts on this facility. The 
proceeds of the term loan are intended for the purchase of houses of employees 
relocated by the Company. The entire principal amount of each term
loan shall be due on the first to occur of (i) the sale of the house securing
such term loan and the (ii) maturity date.

As part of the borrowing arrangements, the Company is required to pay a 
commitment fee of 3/8 of one percent of the average daily amount of the unused 
portion of the credit facility.

The agreement provides for the issuance of letters of credit by the bank on 
the Company's behalf.

The current agreement expires on May 31, 1998. Management expects the 
commitment to be extended by an amendment at that time.

During 1996, the Company refinanced certain construction in progress in its
Newport News manufacturing plant under a sale/leaseback arrangement. The
machines were sold for a sum amount in excess of $2 million. The transaction 
was accounted for as lease financing, wherein the property remains on the 
books subject to depreciation. A financing obligation representing the 
proceeds was recorded and is reduced based on payments under the lease.

Based on an analysis of future operating income for the purpose of realizing
deferred tax assets, management believes that its net deferred tax asset will 
be recoverable in future returns and that its valuation allowance requires no
further adjustment.

The Company's federal income tax return for 1995 is currently being examined 
by the Internal Revenue Service. Management does not believe that this or
subsequent audits will have a material effect on the Company's financial
statements.


NOTE F - EMPLOYEE BENEFIT PLANS

1.  Profit-Sharing and Pension Plan

The Company has a profit-sharing plan pursuant to Section 401 of the Internal 
Revenue Code, whereby participants may contribute up to 20% of their 
compensation. Under the plan, the Company may make two types of contributions 
subject to the discretion of the Board of Directors: (1) Employer matching 
contributions and (2) Profit-Sharing contributions. In order to share in 
either contribution, an employee must complete 1,000 hours of service during 
the Plan Year when the contribution is made. Generally, contributions vest in
the employees' accounts based on their length of service.

During 1997, the employer contribution to the 401k plan was $221,500 compared 
to $103,700 for 1996. No employer contribution was made by the Company during 
1995.


2.  Discretionary Bonus Plan

Under the Officers and Managers Discretionary Bonus Plan for QuesTech and
subordinate units ("the Bonus Plan"), officers and managers of the Company and 
its subsidiaries are selected by management for participation in the Bonus 
Plan. Bonuses are apportioned as a percentage of the recipient's salary and 
are based upon the Company's overall performance and upon the performance of 
the business unit to which the recipient is assigned, subject to review and 
approval by the Chief Executive Officer and/or Chief Operating Officer and the 
Board of Directors.

Amounts charged to expense under this plan were $98,000, $452,200 and $393,500 
at December 31, 1997, 1996 and 1995, respectively.


3.  Postretirement Benefits

The Company has three separate postretirement benefit plans which fall within
the purview of SFAS 106: the Group Health Plan, the Executive Life Insurance
Plan, and the Deferred Compensation Plan.


a.  Group Health Plan

The Group Health Plan extends medical and dental benefit coverage to 
employees, who upon retirement at the age of 65, have completed 20 years of 
full-time employment with the Company, or retire with an individual employment 
agreement which specifically grants coverage approved by the insurance carrier 
of the subject group health policy. The Plan is contributory and contains 
cost-saving features, such as deductibles and coinsurance. The accumulated 
postretirement benefit obligation (APBO) represents the present value of 
insurance claims expected to be presented by eligible employees during their 
retirement years, based on the net premiums paid by the Company on behalf of 
active employees.

For measurement purposes, the annual health care cost trend for 1997 benefits
was 8%, grading down to 5% over four years. The 1% increase in health care 
cost trend was 9% in 1997, grading down to 6% over four years. During 1995, a 
10% medical inflation rate was assumed, grading down to 5% over six years. The 
measurement of the APBO for 1997 and 1996 was based on an assumed discount 
rate of 7.5%.


b.  Executive Life Insurance

The Company maintains life insurance policies, covering certain of its 
officers, both former and active, through their lifetime, in accordance with 
their respective employment agreements. The cost of the insurees' premiums is 
treated as compensation expense.


c.  Officers and Managers Deferred Compensation Plan (DEF COM)

DEF COM allows eligible employee participants to defer current compensation 
and provides supplemental postretirement benefits along with certain specified 
death benefits to the participants' beneficiaries. Postretirement benefits 
under DEF COM are payable upon the participant's termination of employment 
(including retirement), and are paid in equal installments over a period equal 
to the length of time the employee deferred compensation, but no longer than 
ten years. Termination or retirement benefits are based upon the employee's 
actual deferrals plus interest credited annually, as set by the Administrator. 
Supplemental death benefits are payable in some cases over a
period of ten years provided death occurs while the employee participant is
actively employed with the Company.

The Company invests the amounts deferred by employees in life insurance 
policies. Since DEF COM is a defined contribution plan, the accumulated
postretirement benefit obligation as of the transition date has been based on
the actual balances in each participant's account, which consists of
contributions and accrued interest.

4.  Stock Employee Compensation Trust

On February 1, 1994, the Company established a Stock Employee Compensation 
Trust ("SECT") and financed the SECT's repurchase of 221,792 shares of common 
stock owned by two of the Company's former founders. The Company's loan to the 
SECT will be paid down from time to time as the employees exercise and pay for 
their options under the Company's Incentive Stock Option Plan. At December 31, 
1997 and 1996, there were 176,131 unallocated and uncommitted shares held by 
the SECT.


NOTE G - OTHER LONG-TERM OBLIGATIONS

Amounts due to certain founders (no longer affiliated with the Company), under 
a Confidential Settlement Agreement, are included in Other Long-Term 
Obligations. Payments under the agreements will continue until 2004. During 
1995, the Company entered into a similar agreement with another former 
founder. Amounts under the latter agreement payable through 2006 are included 
in Other Long-Term Obligations as well. The cost of the latter agreement was 
included in Other Expense in the 1995 financial statements.


NOTE H - COMMITMENTS AND CONTINGENCIES

1.  Future Minimum Rental Commitments

The following is a schedule by years of the approximate future minimum rental
payments required under operating leases that have initial or remaining
PAGE
<PAGE>
noncancelable lease terms of one year or more as of December 31, 1996:

         Year ending December 31,
         ------------------------

                1997 ..........................      1,809,100
                1998 ..........................      1,723,200
                1999 ..........................      1,034,400
                2000 ..........................        884,800
                2001 ..........................        607,200
                                                    ----------

         Future minimum rental payments .......     $6,058,700
                                                    ==========

Net rent expense under operating leases amounted to approximately $2,053,400,
$1,744,000, and $1,739,900 for the years ended December 31, 1997, 1996 and 
1995, respectively, after being reduced by rental income which was not 
material during the last three years.

2.  Employment Agreements

The Company has employment agreements with two executive officers which
stipulate salary continuation for a period of five years and two years, as a
result of voluntary or involuntary termination, regardless of the change in
control of the Company. The cost of accrued interest and the present value of
compensation changes for these agreements aggregated ($115,353 and $106,700)
during 1997 and 1996, respectively. None of these costs will be paid until the 
subject officers change their employment status with the Company.


NOTE I - STOCK OPTIONS

The Company accounts for its incentive stock options under APB No. 5. The
Company has two incentive stock option plans - 1994 and 1996. The 1994 and 
1996 Stock Option Plans authorize the grant of up to 200,000 and 268,132 
shares of the Company's common stock, respectively. These options which have 
five-year terms vest at a rate of 20% per year from the date of grant. The 
option price of all options granted to date represents the fair market value 
of the Company's common stock at the date of grant. Options to purchase 10,000 
and 72,882 shares are available for future grants under the 1994 and 1996 
Plans, respectively.

Accordingly, no compensation cost has been recognized for the plan. Had
compensation cost for the plan been determined based on the fair value of the
options at the grant dates consistent with the method of SFAS 123, the 
Company's net income and earnings per share would have been:

                                      1997        1996        1995
                                    --------    --------    --------

Net Income       As reported ...    $645,900    $818,300    $520,100
                 Pro forma .....     527,100     705,600     419,000

Basic EPS        As reported ...        0.45        0.59        0.39
                 Pro forma .....        0.37        0.48        0.28

Diluted EPS      As reported ...        0.42        0.54        0.34
                 Pro forma .....        0.36        0.48        0.28
The fair value of each option grant is estimated on the date of the grant 
using the Black-Scholes options-pricing model with the following 
weighted-average assumptions used for grants in 1997, 1996 and 1995: expected 
volatility of 67%, 71% and 71%, respectively; risk free interest rate of 6%; 
and expected lives of four years. The pro forma effect on net income for 1997, 
1996 or 1995 is not representative of the pro forma effect on net income in 
future years because it does not take into consideration pro forma 
compensation expense related to grants made prior to 1995.

A summary of the status of the Company's Incentive Stock Option Plans as of

NOTE J - DISCONTINUED OPERATIONS

During the second quarter of 1998, as a result of the potential merger of
QuesTech and CACI International, a decision was made to dispose of the
commercial packaging operation, QuesTech Packaging, Inc. (QTPI). QTPI designs
and manufactures plastic containers utilizing its patented process and custom
designed manufacturing equipment.

QuesTech management had been exploring various alternatives for disposing of 
QTPI, including an offer from QTPI management to purchase the manufacturing
operations. On August 31, 1998 the sole shareholder of QTPI authorized the
dissolution of QTPI in light of the inability of QTPI management to secure
financing for its proposed purchase. In association with the decision to 
dissolve QTPI, the Company recorded a charge of approximately $2.1 million
representing the anticipated loss on disposal, net of tax effects, during the
third quarter of fiscal year 1998.

The disposal of QTPI has been accounted for as discontinued operations and
accordingly, its operations have been segregated and reported as discontinued
operations in the accompanying Consolidated Balance Sheets, Consolidated
Statements of Earnings and Consolidated Statements of Cash Flows for all years 
presented. Since the decision to dispose of the manufacturing division, the 
Company operates in one business segment on a continuing basis.

The assets and liabilities of QuesTech Packaging, Inc. as of December 31, 1997 
are as follows:

     Current Assets:

<F1>  Represents the allocation of the net purchase price of $34,917,000 to 
all of the assets, liabilities, and intangible assets of QuesTech, Inc. and 
subsidiaries ("QuesTech").  The excess of the purchase price over the fair 
value of the net assets acquired was estimated at $30,946,000 and will be 
amortized on a straight line basis over 30 years.  The preliminary purchase 
price allocation may change during the year ending June 30, 1999 as additional 
information concerning the net asset valuations is obtained.

<F2>  Adjustments to QuesTech's June 30, balances were made to closely reflect 
the actual balances that were acquired.  Cash of $79,000 and net assets of 
discontinued operations of $2,680,000 were eliminated completely.   Income 
taxes receivable were increased by $1,648,000 and deferred taxes were 
increased by $1,500,000.

<F3>  Reflects the estimated increase in line of credit to purchase QuesTech 
and the resulting increase in interest expense of approximately $2,675,000 
less $405,000 of QuesTech interest expense and an adjustment of $178,000 for 
depreciation on fixed assets of discontinued operation.

<F1>  Represents the allocation of the net purchase price of $34,917,000 to 
all of the assets, liabilities and intangible assets of QuesTech, Inc. and 
subsidiaries ("QuesTech").  The excess of the purchase price over the fair 
value of the net assets acquired was estimated at $30,946,000 and will be 
amortized on a straight line basis over 30 years.  The preliminary purchase 
price allocation may change during the year ending June 30, 1999 as additional 
information concerning the net asset valuations is obtained.

<F2>  Adjustments to QuesTech's September 30, balances were made to closely 
reflect the actual balances that were acquired.  Cash of $286,000 and total 
assets of discontinued operations of $4,370,000 were eliminated completely.   
Income taxes receivable were increased by $1,648,000 and deferred taxes were 
increased by $1,500,000.

<F3>  Reflects the estimated increase in line of credit to purchase QuesTech 
and the resulting increase in interest expense of approximately $666,000 less 
$96,000 of QuesTech interest expense and an adjustment of $45,000 for 
depreciation on fixed assets of discontinued operation.

material respects the results of operations, cash flows and stockholders' 
equity, as the case may be, of the Company and its Subsidiaries (including 
QTPI) for the periods therein set forth, in each case in accordance with 
United States generally accepted accounting principles ("GAAP") consistently 
applied, subject, in the case of the three-month period, to normal year-end

Adverse Effect and (b) there have been no dividends or other distributions 
declared or paid in respect of, or any repurchase or redemption by the Company

the Company nor any of its Subsidiaries (including QTPI) has any material 
liabilities or obligations, fixed, accrued, contingent or otherwise 
(collectively, "Liabilities"), that are not fully reflected or provided for 
on, or disclosed in the notes to, the balance sheets included in the Company

Company Plans, the Company and every ERISA Affiliate of the Company are in 
material compliance with all requirements prescribed by all statutes, 
regulations, orders or rules currently in effect, and have in all material 
respects performed all obligations required to be performed by them.  Neither 
the Company nor any ERISA Affiliate of the Company, nor any of their 
directors, officers, employees or agents, nor any trustee or administrator of 
any trust created under the Company Plans, has engaged in or been a party to 
any "prohibited transaction" as defined in Section 4975 of the Code and

sharing plan, all employer contributions accrued for plan years ending prior

              (d)  each Company Plan that is a "group health plan" (as defined

outstanding decree, order, judgment, or stipulation restricting in any manner 
the licensing thereof by the Company or any of its Subsidiaries.  Except as 
set forth in Schedule 3.17, neither the Company nor any of its Subsidiaries 
has entered into any agreement (other than exclusive distribution agreements) 
under which the Company or its Subsidiaries are restricted from selling, 
licensing or otherwise distributing any of its products to any class of 
customers, in any geographic area, during any period of time or in any segment 
of the market.  The Company's products, packaging and documentation contain 
copyright notices sufficient to maintain copyright protection on the 
copyrighted portions of the Company Proprietary Rights.

      3.17.3  Employee Agreements.  Except as set forth on Schedule 3.17, each 
employee, officer and consultant of the Company and its Subsidiaries has 
executed a confidentiality agreement in substantially the form attached hereto 
as Schedule 3.17.3, providing the Company or one of its Subsidiaries with 
title and ownership to the Company Proprietary Rights developed or used by the 
Company and its Subsidiaries in their business.  No employee, officer or 
consultant of the Company and its Subsidiaries is in violation of any term of 
any employment or consulting contract, proprietary information and inventions 
agreement, non-competition agreement, or any other contract or agreement 
relating to the relationship of any such employee, officer or consultant with 
the Company or any previous employer.

3.18  Insurance Contracts.  Schedule 3.18 hereto lists all contracts of 
insurance and indemnity in force at the date hereof with respect to the 
Company and its Subsidiaries.  Such contracts of insurance and indemnity and 
those shown in other Schedules to this Agreement (collectively, the "Company 
Insurance Contracts") insure against such risks, and are in such amounts, as 
appropriate and reasonable considering the Company and its Subsidiaries' 
property, business and operations.  All of the Company Insurance Contracts are 
in full force and effect, with no default thereunder by the Company or its 
Subsidiaries which could permit the insurer to deny payment of claims 
thereunder.  The Company has not received notice from any of its insurance 
carriers that any insurance premiums will be materially increased in the 
future or that any insurance coverage provided under the Company Insurance 
Contracts will not be available in the future on substantially the same terms

Company in connection with the meeting of the Company's stockholders to

as amended or supplemented is referred to herein as the "Proxy Statement") 
shall not, on the date the Proxy Statement is first mailed to the Company's 
stockholders, at the time of the Company Meeting and at the Effective Time, 
contain any untrue statement of a material fact or omit to state any material 
fact required to be stated therein or necessary in order to make the 
statements therein, in light of the circumstances under which they are made, 
not false or misleading; or omit to state any material fact necessary to 
correct any statement in any earlier communication with respect to the 
solicitation of proxies for the Company Meeting which has become false or 
misleading.  The Proxy Statement will comply as to form with the provisions of 
the Exchange Act and the rules and regulations thereunder.  If at any time 
prior to the Effective Time any event relating to the Company or any of its 
affiliates, officers or directors should be discovered by the Company which 
should be set forth in an amendment or a supplement to the Proxy Statement, 
the Company shall promptly inform Parent.  Notwithstanding the foregoing, the 
Company makes no representation or warranty with respect to any information 
supplied by Parent or Merger Sub which is contained in any of the foregoing 
documents.

proceeding in equity or at law).

      4.3.2  No Conflict.  Except as set forth on Schedule 4.3.2 hereto, 
neither execution and delivery of this Agreement by Parent or Merger Sub, nor 
the performance by Parent or Merger Sub of its obligations hereunder, nor the 
consummation by Parent or Merger Sub of the transactions contemplated hereby 
will (a) conflict with or result in a violation of any provision of the 
charter documents or by-laws of Parent or its Subsidiaries (including Merger 
Sub), or (b) with or without the giving of notice or the lapse of time, or 
both, conflict with, or result in any violation or breach of, or constitute a

consummation by Parent or Merger Sub of the transactions contemplated hereby, 
except for (i) the filing of the Certificate of Merger with the Secretaries of 
State of the State of Delaware and the Commonwealth of Virginia, (iii) filing 
with the Federal Trade Commission and the United States Department of Justice 
pursuant to the provisions of the H-S-R Act, and  (iii) such other consents,

1, 1993.  Parent heretofore has delivered or made available to counsel for the

hereinafter referred to as the "Parent Reports").  As of their respective 
dates, the Parent Reports complied in all material respects with all 
applicable requirements of the Securities Act and the Exchange Act and the 
rules and regulations promulgated thereunder, and did not contain any untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading.  The financial 
statements (including any related notes) of Parent included in the Parent

(except as otherwise stated in the financial statements), and present fairly 
the consolidated financial position, results of operations and changes in 
financial position of Parent and its consolidated Subsidiaries as of the dates 
and for the periods indicated, subject, in the case of unaudited interim 
consolidated financial statements, to (i) the absence of certain notes thereto 
and (ii) normal year-end audit adjustments which are not in the aggregate 
material.  The consolidated balance sheet of Parent and its subsidiaries at 
June 30, 1997, including the notes thereto, is hereinafter referred to as the

4.5   Absence of Material Adverse Changes.  Since the date of the Parent 
Balance Sheet, Parent has not suffered any Parent Material Adverse Effect, nor 
has there occurred or arisen any event, condition or state of facts of any 
character that could reasonably be expected to result in a Parent Material 
Adverse Effect. 

4.6   Litigation and Audits.  Except for any claim, action, suit or proceeding 
disclosed in the Parent Reports or set forth on Schedule 4.6 hereto, (a) there 
is no investigation by any Governmental Entity with respect to Parent or its 
Subsidiaries pending or, to the knowledge of Parent, threatened, nor has any 
Governmental Entity indicated to Parent or any of its Subsidiaries an 
intention to conduct the same, and (b) there is no claim, action, suit, 
arbitration or proceeding pending or threatened against or involving Parent or 
any of its Subsidiaries, or any of its or their assets or properties, at law 
or in equity, or before any arbitrator or Governmental Entity, in each case 
that, if adversely determined, either singly or in the aggregate, would 
prevent or materially delay the consummation of the transactions contemplated 
hereby. 

4.7   Proxy Statement.  The information provided by Parent or Merger Sub for 
inclusion in the Proxy Statement shall not, on the date the Proxy Statement is 
first mailed to the Company's stockholders, at the time of the Company Meeting 
and at the Effective Time, contain any untrue statement of a material fact or 
omit to state any material fact required to be stated therein or necessary in 
order to make the statements therein, in light of the circumstances under 
which they are made, not false or misleading; or omit to state any material 
fact necessary to correct any statement in any earlier communication with 
respect to the solicitation of proxies for the Company Meeting which has 
become false or misleading.  If at any time prior to the Effective Time any 
event relating to Parent, Merger Sub or any of their respective affiliates, 
officers or directors should be discovered by Parent or Merger Sub which 
should be set forth in an amendment or a supplement to the Proxy Statement, 
Parent or Merger Sub shall promptly inform the Company.  Notwithstanding the

Agreement, the Company shall prepare and file with the SEC the Proxy

6.3   Amendment of Stock Options.  Promptly after execution of this Agreement, 
the Company shall take such action as may be practicable under the terms of 
all outstanding Company Stock Options and the Company SECT to ensure that at 
the Effective Time, each Company Stock Option then outstanding shall be 
converted into the right to receive payment from the Company SECT of the 
amount of the excess, if any, of the Merger Price Per Share for each share of 
Company Common Stock  for which that Company Stock Option was theretofore 
exercisable over the exercise price per share for each such share of Company 
Common Stock.  It is understood that, since the Company will not receive the

combination, sale of substantial assets, sale of shares of capital stock, or 
similar transaction involving the Company or any of its Subsidiaries (all such 
transactions being referred to herein as "Acquisition Proposals").  
Notwithstanding the foregoing, the Company may furnish information concerning 
its business, properties, or assets to and enter into negotiations with a 
corporation, partnership, person, or other entity or group, if the party 
receives an unsolicited Acquisition Proposal and outside counsel to the 
Company advises the Company's Board of Directors in writing that the Board's 
fiduciary responsibilities under applicable law require that such information 
be provided or negotiations be held with the person presenting the Acquisition 
Proposal in order to avoid a breach of such fiduciary responsibilities.

6.6   Expenses.  Each party hereto shall be responsible for its own costs and 
expenses in connection with the Merger, including fees and disbursements of

accountants.

operating data and other information as to its business, customers, vendors 
and properties and those of its Subsidiaries as Parent may from time to time 
reasonably request.

terms and existence of this Agreement) shall be developed by Parent, subject 
to the Company's review.  The Company and Parent agree that each party's 
non-disclosure obligations contained in the Letter of Intent shall remain in 
full force and effect in accordance with the terms of such Agreement.

6.10  No Solicitation of Employees.  Parent and the Company agree that between 
the date of this Agreement and the Effective Time or the date one year after 
the date, if any, on which this Agreement is earlier terminated pursuant to 
its terms, neither party shall solicit, induce or recruit any of the other 
party's employees to leave their employment, otherwise than in response to 
general advertisements or solicitations not directed specially to employees of 
the other party.

be taken, all action and to do, or cause to be done, all things necessary, 
proper or advisable under applicable laws and regulations to consummate and 
make effective the Merger and the other transactions contemplated by this 
Agreement.  Without limiting the generality of the foregoing, the Company and 
Parent each will use all reasonable efforts to obtain all approvals, 
authorizations, consents and waivers from, and give all notices to, any public 
or private third parties that are necessary on its part in order to effect the 
transactions contemplated hereby.

warranty, covenant or agreement contained in this Agreement on the part of the 
Company and such breach has not been cured within ten business days after 
written notice to the Company (provided, that neither Parent nor Merger Sub is

hereof, as the case may be, will not be satisfied;

      (c)  by Parent, if the Company or its Board of Directors shall have (i)

limitation, having failed (without the consent of Parent) after a reasonable 
period of time to reject or disapprove any Acquisition Proposal (or after a reas
onable period of time to recommend to its shareholders such rejection or

preparing for the combination, a fee of one million dollars ($1,000,000);

assets of the Company or Parent as a result of the Merger; (iii) if the 
Company's stockholders do not approve this Agreement and the transactions

accretive to net earnings.  QuesTech, headquartered in Falls Church, Virginia,

QuesTech reported revenues of $78 million.

CACI organization," said Dr. J. P. (Jack) London, CACI Chairman and CEO.  "The

for our clients".  Ron Ross, CACI President and Chief Operating Officer added, 
"We believe that information assurance and security is increasingly critical 
in providing our customers infocomm solutions in the years ahead.  The unique 
combination of CACI's and QuesTech's capabilities positions us as a leader in 
that arena."
