        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

A.   Basis of Presentation
- --------------------------

The accompanying unaudited consolidated financial statements have been 
prepared pursuant to the rules and regulations of the Securities and Exchange 
Commission.  Certain information and note disclosures normally included in the 
annual financial statements, prepared in accordance with generally accepted 
accounting principles, have been condensed or omitted pursuant to those rules 
and regulations, although the Company believes that the disclosures made are 
adequate to make the information presented not misleading.

In the opinion of management, the accompanying unaudited  consolidated 
financial statements reflect all necessary adjustments and reclassifications 
(all of which are of a normal, recurring nature) that are necessary for fair 
presentation for the periods presented.  It is suggested that these 
consolidated financial statements be read in conjunction with the consolidated 
financial statements and the notes thereto included in the Company's latest 
annual report to the Securities and Exchange Commission on Form 10-K for the 
year ended June 30, 1998.

Certain reclassifications have been made to the prior period's financial 
statements to conform to the current presentation.

C.   Acquisitions
- -----------------

On November 13, 1998, the Company acquired all of the common stock of 
QuesTech, Inc. ("QuesTech"), a company that specializes in the development and 
application of information technology and engineering services for the defense 
and national security communities, for $18.13 per share in cash.  The total 
consideration paid by CACI, including the assumption of liabilities, was 
approximately $42 million.  The transaction was funded through borrowings 
under the Company's existing line of credit with a group of banks.  For the 
year ended December 31, 1997, QuesTech reported revenues of $78.5 million.  
The transaction has been recorded using the purchase method of accounting.  
Approximately $31 million of the purchase consideration has been preliminarily 
allocated to goodwill based upon the excess of the purchase price over the 
estimated fair value of net assets acquired, and will be amortized over 30 
years.  The preliminary purchase price allocation may change during the year 
ending June 30, 1999, as additional information concerning the net asset 
valuation is obtained.  QuesTech contributed revenues of $8.9 million for the 
period from November 13, 1998 to December 31, 1998.

On August 13, 1998, the Company purchased the assets of Information Decision 
System ("IDS") for $2.6 million  in cash and, therefore, the transaction has 
been recorded using the purchase method of accounting.  IDS provided internet 
access to demographic site information and the acquisition is expected to 
enhance the current U.S. market share of the Company's Marketing Systems Group 
("MSG") in the industry.  Approximately $2.4 million has been preliminarily 
allocated to goodwill, based upon the excess of the purchase price over the 
estimated fair value of net assets acquired, and will be amortized over 15 
years.  Since its acquisition, the operations acquired from IDS have 
contributed approximately $0.2 million in revenue through September 30, 1998.  
The acquisition was financed with available bank borrowings.

D.  Other Long-Term Obligations
- -------------------------------

The Company acquired certain long-term obligations in connection with the 
QuesTech transaction discussed in Note C.  At December 31, 1998, approximately 
$3.0 million was accrued in connection with the Officers and Managers Deferred 
Compensation Plan ("DefCom").  DefCom 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 DefCom are payable upon the 
participant's termination of employment, 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 
determined by the Administrator.  Supplemental death benefits are payable, in 
some cases, over a period of ten years provided death occurs while the 
participant is an active employee of the Company.  DefCom is a non-qualified, 
defined contribution plan which has been valued based on the actual 
participant account balances plus interest earned to date.  The remaining 
liability consists primarily of amounts accrued in connection with other 
benefit plans which provide medical and insurance coverage.  The liability 
associated with these other plans is actuarily determined on an annual basis.

E.   Commitments and Contingencies
- ----------------------------------

The Company is involved in various lawsuits, claims, and administrative 
proceedings arising in the normal course of business.  Management is of the 
opinion that any liability or loss associated with such matters will not have 
a material adverse effect on the Company's operations and liquidity.

F.   Recent Accounting Pronouncements
- -------------------------------------

In June 1997, the Financial Accounting Standards Board ("FASB") issued 
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting 
Comprehensive Income," and SFAS No. 131, "Disclosures About Segments of an 
Enterprise and Related Information."  As specified by these Statements, the 
Company will apply these Statements beginning in fiscal 1999 and reclassify 
its annual financial statements for earlier periods for comparative purposes.

SFAS No. 130 requires that all items defined 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.  The 
Company adopted  SFAS No. 130 during the first quarter of fiscal 1999 and has 
reported the effects of foreign currency translation gains or losses as a 
component of comprehensive income in a separate financial statement.

SFAS No. 131 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, geographics areas, and major customers.  This Statement supersedes 
SFAS No. 14, "Financial Reporting for Segments of a Business Enterprise," but 
retains the requirement to report information about major customers.  It 
amends SFAS No. 94, "Consolidation of All Majority-Owned Subsidiaries," to 
remove the special disclosures requirements for previously unconsolidated 
subsidiaries.  At this point, the Company has not fully determined the impact 
of the adoption of SFAS No. 131.

For the three months and six months ended December 31, 1998, the Company's 
total revenues increased by 31%, or $24.6 million, and by 31%, or $46.3 
million, respectively, over the same periods last year.  Approximately $15.4 
million, or 63% of the increase, and $26.5 million, or 57% of the increase, 
was achieved through internal or organizational growth in all market segments 
for the quarter and six months ended December 31, 1998, respectively, over the 
same periods a year ago.  The remaining increase of $9.2 million and $19.8 
million for the three and six months of FY99, respectively, as compared to 
FY98 was primarily the result of acquisitions described below.

On November 13, 1998, the Company acquired 100% of the issued and outstanding 
common stock of QuesTech, Inc. ("QuesTech") which contributed approximately 
$8.9 million of incremental revenues for the three and six months ended 
December 31, 1998.  On August 13, 1998, the Company purchased the assets of 
Information Decision Systems ("IDS").  Since its acquisition, the operations 
of IDS have contributed approximately $0.4 million of revenues through 
December 31, 1998.  In the prior year, the Company purchased the business and 
assets of Government Systems, Inc. ("GSI") on  November 1, 1997, which 
generated incremental revenues of $9.6 million for the first three months of 
FY99.

Department of Defense revenues increased 24%, or $9.3 million, for the 
quarter, and 19%, or $14.7 million, for the first six months.  The QuesTech 
and GSI acquisitions accounted for primarily all of the growth, contributing a 
combined  $7.8 million and $11.8 million for the three and six month periods, 
respectively.

Revenues from Federal Civilian agencies increased 52%, or $10.9 million, for 
the quarter, and 55% or $21.8 million, for the first six months of FY99, as 
compared to the same periods a year ago.  Approximately 54% of Federal 
Civilian agency revenues are derived from the Department of Justice ("DoJ") in 
providing litigation support services and in developing an automated debt 
collection system.  Revenues for DoJ were $16.1 million and $32.8 million for 
the quarter and six months ended December 31, 1998, as compared to $13.9 
million and $29.0 million for the respective periods a year ago.  Significant 
growth in contracts with Civilian agencies other than DoJ was led by expanding 
efforts under contract vehicles with the Federal Aviation Administration 
("FAA") and the General Services Administration ("GSA").  A higher level of 
communication services and equipment provided to the FAA has resulted in 
incremental revenues of $1.5 million for the second quarter of FY99 and of 
$5.2 million for the first half of FY99.  The remaining increase of $7.2 
million for the second quarter and $12.8 million for the first half of FY99 
was mainly generated from growth in a GSA multiple task order contract, which 
provides primarily Year 2000 software renovation services to several Civilian 
agencies.

During the quarter and six months ended December 31, 1998, commercial revenues 
increased by 8%, or $1.4 million, and 14%, or $4.5 million, respectively, over 
the same periods a year ago.  These increases are primarily the result of 
increased demand for European systems integration services provided by our 
Marketing Systems Group ("MSG") in the United Kingdom.

Revenues from state and local governments increased $3.0 million and $5.3 
million for the quarter and six months ended December 31, 1998, as compared to 
the same periods a year ago due to increased demand for Year 2000 software 
renovation services.

The following table sets forth the relative percentage that certain items of 
expense and earnings bear to revenues for the quarter and six months ended 
December 31, 1998 and December 31, 1997, respectively.

INCOME FROM OPERATIONS. Operating income increased 25% and 28% for the quarter 
and six months ended December 31, 1998 as compared to the same periods a year 
ago.  This is due to the 31% growth in revenues for both the second quarter 
and first half of FY99 offset by a higher proportion of other direct costs to 
total direct costs which generally provide a lower margin.

As a percentage of revenues, total direct costs for the second quarter of FY99 
were 57.3% versus 53.8% a year ago and for the first six months of FY99 were 
56.6% versus 53.8% a year ago.  Direct costs include direct labor and other 
direct costs such as equipment purchases, subcontract costs and travel 
expenses.  The largest component of direct costs, direct labor was $29.9 
million and $25.2 for the second quarter of FY99 and FY98, respectively.  For 
the six months ended  December 31, 1998 and 1997, direct labor was $57.2 
million and $49.0 million, respectively.  Other direct costs were $29.5 
million and $17.4 million for the second quarters of FY99 and FY98, 
respectively, and $53.8 million versus $31.6 million for the first six months 
of FY99 and FY98, respectively.  Other direct costs have grown at a more rapid 
pace as the Company has a higher number of contracts with an increased level 
of other direct costs. The most notable increases have come from equipment 
purchases for contracts with the FAA and DoJ as well as subcontract and travel 
costs incurred with Year 2000 software services.
Indirect costs and selling expenses include fringe benefits, marketing and bid 
proposal costs, indirect labor and other discretionary costs, most of which 
are highly variable.  As a percentage of revenues, indirect costs have 
decreased due to the impact of higher other direct costs on revenues for the 
second quarter and first half of FY99.

Depreciation and amortization expense increased slightly in the second quarter 
and first half of FY99 as compared to the same periods a year ago, primarily 
due to the acquisition of QuesTech.

Goodwill amortization expense has increased $0.3 million for the second 
quarter and $0.6 million for the first half of FY99 as compared to the same 
periods a year ago due to the acquisitions of QuesTech and IDS in the current 
fiscal year as well as the incremental impact from the GSI acquisition in the 
prior year.

INTEREST EXPENSE.  Interest expense increased $0.5 million and $0.7 million 
for the second quarter and first six months of FY99 as compared to the same 
periods in FY98.  This is directly attributable to the increased borrowings of 
$42 million necessary to complete the QuesTech acquisition as well as an 
increase in average borrowings since the acquisition of GSI in the prior year.

INCOME TAXES.  The effective income tax rate for the quarter and six months 
ended December 31, 1998 was 37.8% and 37.4% as compared to 38.0% for both the 
quarter and six months ended December 31, 1997.  The slight decrease for  both 
periods is due to a lower effective state income tax rate offset by the impact 
of non-deductible goodwill amortization from the QuesTech acquisition.  
Liquidity and Capital Resources
- ------------------------------- 

Historically, the Company's positive cash flow from operations and available 
credit facilities provided adequate liquidity and working capital to fully 
fund the Company's operational needs and support the acquisition activities.  
Working capital was $71.8 million and $54.9 million as of December 31, 1998 
and June 30, 1998, respectively.  The increase in working capital in the first 
six months of FY99 is related both to internal growth and to the QuesTech 
acquisition.  Operating activities used cash of $2.3 million for the six 
months of FY99 as compared to FY98 when operating activities provided cash of 
$8.6 million.  This decrease in cash provided by operating activities since 
the prior year is primarily due to $6.0 million of income tax payments in the 
first half of FY99 as compared to $3.1 million of income tax refunds in FY98.  
In addition, the decrease is due to cash payments related to higher other 
direct costs as well as growth in receivables resulting from the 31% growth in 
revenues for the first six months of FY99 as compared to the same period of 
FY98.

The Company used $47.8 million in investing activities for the six months 
ended December 31, 1998 versus $38.1 million for the same period a year ago.  
This is primarily due to the acquisitions of QuesTech of $41.6 million and of 
IDS for $2.6 million in FY99, and of GSI for $33.5 million in FY98.

The Company financed its investing activities from operating cash flows and 
from a net increase in borrowings of $47.6 million under its line of credit.

In June 1998, the Company executed a new five-year unsecured revolving line of 
credit, which permits borrowings of up to $125 million with annual sublimits 
on amounts borrowed for acquisitions.  The Company also maintains a 500,000 
pound sterling unsecured line of credit in London, England, which expires in 
November 1999.  At December 31, 1998, the Company had approximately $48.5 
million available for borrowings under its lines of credit.

The Company believes that the combination of internally generated funds, 
available bank borrowings and cash on hand will provide the required liquidity 
and capital resources for the foreseeable future.

Year 2000
- --------- 

The following discussion addresses the Company's response to the Year 2000 
issue, caused by the fact that many computer systems have not been designed to 
process dates for the Year 2000 and beyond.

The Company has undertaken a multi-faceted compliance program to address its 
readiness to handle the date issue in connection with both Information 
Technology ("IT") and non-IT systems (such as those using embedded chip 
technology) in the following areas: CACI-developed software products and 
systems, infrastructure hardware and software applications, business 
applications, office equipment, leasehold facilities, and critical business 
partners.  The Company believes that continued awareness and communication are 
critical to the successful execution of this program. We are currently 
addressing each one of these elements listed above.

Through the use of questionnaires, compliance testing, and continued 
discussions, we have determined that a substantial portion of the CACI 
software products currently offered are compliant and have published the 
status of all CACI software products on the Company's internet site at 
http://www.caci.com.  The Company's plan is to achieve full compliance by July 
1999.  Regarding the custom systems previously developed by CACI for its 
customers, the Company is working to evaluate the contractual commitments that 
would obligate CACI to remediate non-compliant systems, as well as CACI's 
potential legal exposure concerning systems for which CACI has no continuing 
express warranty or maintenance obligations. 

Based on the present state of our knowledge and of the law as it applies to 
this aspect of the Year 2000 issue, we are unable at this time to determine 
the full extent of exposure or to estimate the probable cost and timing of any 
required remediation.

Over the past few years, the Company has made a concerted effort to update its 
desktop and laptop computers and its internal communications network equipment 
and software.  With current technology in place, the Company believes that 
most of these systems are already compliant.  The Company has taken the 
additional step of requesting that its 160 suppliers of such systems and 
components provide information as to Year 2000 compliance of their products.  
To date, approximately 60% have been found to be compliant or require only 
minor changes.  The Company is proceeding in accordance with a plan that is 
scheduled to achieve material compliance of these systems by June 1999.

At this point, the Company has identified the following systems as our key 
business applications: finance & project management, payroll, human resources, 
and contracts.  Our human resources information and contracts database systems 
are largely compliant with only minor issues remaining. We are currently 
reviewing the project forecasting systems for Year 2000 readiness.  In 
addition, we recently completed the upgrade of our payroll system to a fully 
compliant MS-Windows(R)-based version supplied by an outside vendor. 
In January 1998, we began our implementation of a new finance system, which is 
supplied by Deltek Systems, a leading supplier of such systems to the 
government contracting industry.  This system is represented as being 
compliant and our plan is on schedule to have it implemented by June 1999. 

We have and will continue to determine and assess our critical business 
partners as a part of our compliance program.  Presently, such significant 
business partners include, but are not limited to, our  suppliers, the utility 
companies, our bank lending group, an outside vendor used to process payroll, 
insurance and benefit providers, and property management firms.  CACI's 
operations are dependent to varying degrees on the readiness of these and 
other partners. CACI has issued questionnaires to identified business 
partners.  To date, the number of responses received indicate that many of our 
business partners are actively addressing the Year 2000 issue. The Company is 
continuing to aggressively pursue responses in order to complete our 
evaluations and develop any appropriate contingency plans, as necessary.

The Company is heavily dependent upon the effectiveness of its customers' 
systems, principally in the U.S. Government, for the administration of 
contracts and payment of the Company's invoices.  The Company has made formal 
inquiries and continues to vigorously pursue responses concerning the efforts 
of its larger U.S. Government customers to determine the status and encourage 
correction of any problems in their systems.  The primary concern is that 
there will be delays in contract payments to the Company, which would require 
a temporary increase in working capital.  The Company has substantial 
borrowing capacity available under its current line of credit, which extends 
to June 2003, but will further evaluate the potential cash flow impact of the 
problem and determine if additional steps are necessary to insure that 
adequate contingency financing is available.

The financial impact of preparing the Company to be compliant is not fully 
determinable at this time.  Presently, the most significant costs are related 
to our implementation of our new business systems in finance and project 
management, which are discussed above.  Costs for this project, including 
software, hardware, consulting fees and labor are estimated at $2 million, of 
which approximately 50% has been spent to date.  These costs are being 
capitalized and will be depreciated when the system is operational.  In 
addition, we anticipate incurring approximately $200 thousand in incremental, 
internal labor costs that relate specifically to management of the Year 2000 
compliance program.  The Company has devoted one full-time individual, an 
oversight committee of 15 individuals and approximately 40 LAN administrators 
at various offsite locations to communicate and implement all aspects of the 
Year 2000 compliance program.  The Company has found that many of the upgrades 
or patches necessary to fix the software are being provided at no cost by 
major vendors.  In addition, a majority of the CACI software product upgrades 
are currently planned using existing technical staff without a significant 
effect on other new product development.

In summary, the Company has established a Year 2000 compliance program plan 
which is progressing  as described above. We have not yet proceeded far enough 
through performance of that plan to make a more complete assessment of the 
Company's state of readiness, costs to address Year 2000 issues, or risks to 
the Company.  Moreover, because the Company's Year 2000 compliance program 
plan appears, on the basis of our present knowledge, to adequately address the 
matter, we have not yet developed specific contingency plans.  Investors 
should be aware of the fact that the process of addressing the Year 2000 issue 
is necessarily incremental.  The Company will continue to report on the status 
of its Year 2000 compliance program.  Investors are cautioned, however, that 
the Company's assessment of its readiness, of the costs of performing the 
program and the risks attended thereto, and of the need for any contingency 
plans may change materially in the future as we gain more complete knowledge 
and proceed further through plan performance.

ITEM 1. LEGAL PROCEEDINGS

CACI, INC. - FEDERAL v. Arizona Department of Transportation
- ------------------------------------------------------------ 
 
Reference is made to Part II, Item 1, Legal Proceedings, in the Registrant's  
Report on Form 10-Q for the quarter ended September 30, 1998 for the most 
recently filed information concerning the lawsuit filed on June 25, 1996, by 
CACI, INC. - FEDERAL ("CACI"), the Registrant's wholly-owned subsidiary, in 
Superior Court for Maricopa County, Arizona, against the Arizona Department of 
Transportation ("ADOT").  This suit seeks the following: (i) a declaratory  
judgment that the disputes procedures mandated by the Arizona Procurement Code 
is unconstitutional; (ii) a declaratory judgment that ADOT cannot assert 
claims against CACI under the mandated disputes procedure; (iii) a declaratory 
judgment that ADOT is not entitled to recover consequential damages in 
connection with the dispute; (iv) $2,938,990 plus interest in breach of 
contract damages; (v) the return of CACI's property seized by ADOT in 
connection with the termination of the contract; and (vi) lawyers' fees.  ADOT 
has counterclaimed, seeking in excess of $100 million in damages allegedly 
caused by CACI's breach of contract.

Since the filing of Registrant's report indicated above, the parties have 
reopened settlement discussions, with no resolution to date.
