                            GTSI CORP. AND SUBSIDIARY

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)

1.       Basis of Presentation

         The accompanying unaudited consolidated financial statements of GTSI
Corp. ("GTSI" or the "Company") have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission ("SEC") and, therefore,
omit or condense certain footnotes and other information normally included in
financial statements prepared in accordance with generally accepted accounting
principles. This report should be read in conjunction with the audited financial
statements for the year ended December 31, 2003 and the accompanying Notes to
the Financial Statements, contained in the Company's 2003 Annual Report on Form
10-K. In the opinion of Management, all adjustments, consisting primarily of
normal recurring adjustments, necessary for a fair presentation of interim
period results have been included. The results of operations for the three month
period ended March 31, 2004 are not necessarily indicative of the results that
may be expected for the full year, or future periods.

New Accounting Pronouncements

         In January 2003, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 46, "Consolidation of Variable Interest Entities (FIN No.
46). FIN No. 46 clarifies the application of Accounting Research Bulletin No.
51, "Consolidated Financial Statements" to certain entities in which equity
investors do not have the characteristics of a controlling financial interest or
do not have sufficient equity at risk for the entity to finance its activities
without additional subordinated financial support from the other parties. FIN
No. 46 applies to variable interest entities created after January 31, 2003. The
consolidation requirements apply to older entities in the first fiscal year or
interim period beginning after December 15, 2003, which is the Company's first
quarter of fiscal year 2004. The Company has adopted FIN No. 46 with no material
impact on its condensed consolidated financial statements.

2.       Consolidation

         The consolidated financial statements include the accounts of the
Company and its wholly owned subsidiary. Material intercompany transactions and
balances have been eliminated.

3.       Sales of Lease Receivables

         The Company sells products to certain customers under sales-type lease
arrangements. The Company accounts for its sales-type leases according to the
provisions of Statement of Financial Accounting Standards (SFAS) No. 13,
"Accounting for Leases," and accordingly, recognizes current and long-term lease
receivables, net of unearned finance income on the accompanying balance sheets.
The Company periodically sells lease receivables to various, unrelated financing
companies. The Company accounts for its sales of lease receivables in accordance
with SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets
and Extinguishments of Liabilities - a Replacement of FASB Statement No. 125."
In accordance with the criteria set forth in SFAS No. 140, lease receivables
amounting to $13.7 million were sold during the quarter ended March 31, 2004. In
the same quarter of the previous year, lease receivables amounting to $4.7
million were sold.

4.       Capitalized Software

         The Company is implementing an enterprise resource planning (ERP)
system to replace its current fulfillment system. Implementation of the ERP
system is designed to improve management information and gain operating
efficiencies. As of March 31, 2004 the Company has approximately $5.8 million of
costs capitalized related to this project, of which approximately $1.8 million
was capitalized in the three month period ended March 31, 2004.

5.       Notes Payable to Banks

         The Company has a $125 million credit facility with a group of banks
(the Credit Facility). The Credit Facility, which matures on February 28,
2005, includes a revolving line of credit (the Revolver) and a provision for
inventory financing of vendor products (the Wholesale Financing Facility).
Borrowing under the Revolver is limited to 85% of eligible accounts receivable.
The Revolver is secured by substantially all of the Company's assets. Borrowing
under the Wholesale Financing Facility is limited to 100% of the value of the
inventory. The Wholesale Financing Facility is secured by the underlying
inventory. The Credit Facility carries an interest rate indexed to LIBOR plus
1.75 percentage points. The Credit Facility also contains certain covenants as
well as provisions specifying compliance with certain quarterly and annual
financial ratios. At March 31, 2004, the Company was in compliance with all
financial covenants set forth in the Credit Facility and had additional
available credit on the Credit Facility of $70.3 million.

6.       Accrued Warranty Liabilities

         The Company offers warranties on sales under certain products specific
to the terms of the customer agreements. Standard warranties require repair or
replacement of defective products reported during the warranty period at no cost
to the customer. The Company records an estimate for warranty expenses based on
its actual historical return rates and repair costs at the time of sale.

Accrued warranty liability as of December 31, 2003          $ 4,555

Warranty activity from January 1, 2004 to March 31, 2004:

     Charges made against the warranty                         (538)

* At March 31 2004 and 2003 there were approximately 924,000 and 803,000 shares,
respectively, of potentially dilutive options that are not included because the
net losses for the quarters makes their impact anti-dilutive.

8.       Stock Option Accounting

         The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting Principle
Board (APB) Opinion No. 25 "Accounting for Stock Issued to Employees" and
related interpretations. Accordingly, compensation expense for stock options is
measured as the excess, if any, of the fair market value of the Company's stock
at the date of the grant over the exercise price of the related option.

         Had compensation costs for the Company's stock options been determined
based on SFAS No. 123 "Accounting for Stock Based Compensation" using an
accepted fair valuation method, the Company's net income and earnings per share
would have been as follows (in thousands, except per share amounts):


                                                    Three Months Ended March 31,

9.       Commitments and Contingencies

         The Company is occasionally a defendant in litigation incidental to its
business. The Company believes that none of such litigation currently pending
against it, individually or in the aggregate, will have a material adverse
effect on the Company's financial condition or results of operations.

         In November 2003, GTSI was served with a $25 million lawsuit, with
treble damages, related to the termination of a former subcontractor. This suit
follows the Company's earlier lawsuit against the former subcontractor.
Management believes these claims are without merit and intends to vigorously
defend this lawsuit, but the ultimate outcome of this matter is uncertain.
Management is unable to estimate the amount GTSI may have to pay related to this
matter. No amounts have been accrued as of March 31, 2004.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The following discussion and analysis is provided to increase the
understanding of, and should be read in conjunction with, the Consolidated
Financial Statements and Notes thereto included elsewhere in this Report, as
well as the Company's consolidated financial statements and notes thereto
incorporated into its Annual Report on Form 10-K for the year ended December 31,
2003. Historical results and percentage relationships among any amounts in the
Consolidated Financial Statements are not necessarily indicative of trends in
operating results for any future period.

First Quarter 2004 Overview

         Historically, the Company has experienced net losses in the first
quarter of the year due to the buying pattern of the Government. For the first
quarter of 2004, the Company experienced a year over year improvement to its net
loss despite a minimal change in revenues in the period. The Company saw an
increase in bookings for the quarter driven by a strong month of March. Backlog
as of March 31, 2004 increased to $98.0 million from $72.2 million as of March
31, 2003. Gross margin increased $2.0 million to $18.1 million due primarily to
higher vendor volume incentive payments. The Company continues to focus its
sales efforts on vendors that are offering these volume incentive programs and
its sales force is given incentives to sell these vendors products. Operating
expenses for the period also increased by $2.0 million. During the quarter the
Company incurred costs related to three major initiatives. First, the Company
introduced its new branding campaign, "I Rely on GTSI". The Company also
incurred expenses related to its efforts to comply with the requirements set
forth by Section 404 of the Sarbanes-Oxley Act (SOX 404). Finally, the Company
continued to invest in its implementation of enterprise resource planning (ERP)
system to replace its current fulfillment system. Offsetting the increase in
operating expenses, the Company's interest and other income increased by $0.6
million to $1.4 million due to an increase in lease interest income from the
sale of leases of equipment to government customers.

Company Overview

         GTSI is a recognized information technology (IT) solutions leader,
providing products and services to federal, state, and local government
customers worldwide. For over two decades GTSI has served the public sector by
teaming up with global IT leaders such as HP, Panasonic, Microsoft, Sun and
Cisco. GTSI seeks to deliver maximum value through its broad range of products,
extensive contract portfolio, and ISO 9002-registered logistics. Through its
Technology Teams, GTSI delivers "best of breed" products and services to help
its customers realize strong value for their IT investments. The Technology
Teams consist of technical experts who support a wide range of integrated IT
solutions in such areas as high performance computing, advanced networking,
mobile and wireless solutions, high availability storage and information
assurance. GTSI continues to broaden its leadership in electronic commerce and
procurement through its federally focused website, gtsi.com that provides
customized shopping zones to meet customers' personalized needs. GTSI is
headquartered in Northern Virginia, outside of Washington, D.C.

         Federal Government IT spending has grown at a 14% compounded annual
rate since 2000, and the Company believes that government IT spending will
continue to be robust in the foreseeable future. The Company's revenue has grown
at a 13% compounded annual rate since 2000. Changes in sales throughout the
Company's history have been attributable to increased or decreased unit sales,
to expansion of the Company's product offerings (e.g., peripherals, personal
computers and networking, Unix servers/workstation and internet products), to
the addition/removal of vendors, and to the addition or expiration of sales
contract vehicles.

                                     - 10 -

         A substantial portion of the Company's contracts is fixed-price and
indefinite delivery/ indefinite quantity ("IDIQ"). The uncertainties related to
future contract performance costs, product life cycles, quantities to be shipped
and delivery dates, among other factors, make it difficult to predict the future
sales and profits, if any, which may result from such contracts.

         GTSI qualified as a "small business" under several of the GWACs and
BPAs it holds based upon GTSI's size status at the time of the contracts'
original award. As a small business, GTSI enjoys a number of benefits, including
being able to compete for small business set-aside contracts, qualifying as a
small business subcontractor, bidding pursuant to small purchase procedures
directed to non-manufacturer small business, and offering Government agencies an
avenue to meet their internal small business purchase goals.

         A company's size status under a contract is based on the North American
Industry Classification System ("NAICS") Code referenced in the subject
contract's solicitation. Dependent on the NAICS Code referenced in a
solicitation, GTSI may or may not qualify as a small business for new contract
awards. Under a Federal Acquisition Regulation (FAR) Deviation issued by GSA on
October 10, 2002, GTSI will be required to recertify its size status on its GSA
Schedule Contract no later than 2007. At such time, GTSI may not qualify as a
small business for new contract awards under the GSA Schedule. In addition, new
legislation or regulations may require GTSI to recertify its size status on its
GSA Schedule sooner than 2007. GTSI cannot predict whether it would continue to
qualify as a small business at the time of recertification. To mitigate any
potential adverse impact, GTSI has developed strategic relationships with small
minority-owned businesses that benefit from the small business benefits
described above. GTSI acts as both a supplier and prime contractor to these
small minority-owned businesses.

         Legislation is periodically introduced in Congress that may change the
federal government's procurement practices, and agencies from time to time may
issue new regulations or modify existing regulations that may also change the
government's procurement practices. GTSI cannot predict whether any legislative
or regulatory proposals will be adopted or, if adopted, the impact upon its
operating results. Changes in the structure, composition and/or buying patterns
of the Government, either alone or in combination with competitive conditions or
other factors, could adversely affect future results.

         Noncompliance with Government procurement regulations or contract
provisions could result in termination of Government contracts, substantial
monetary fines or damages, suspension or debarment from doing business with the
Government and civil or criminal liability. During the term of any suspension or
debarment by any Government agency, the contractor could be prohibited from
competing for or being awarded any contract by any Government agency. In
addition, substantially all of the Company's Government contracts are terminable
at any time at the Government's convenience or upon default. Upon termination of
a Government contract for default, the Government may also seek to recover from
the defaulting contractor the increased costs of procuring the specified goods
and services from a different contractor. The effect of any of these possible
Government actions or the adoption of new or modified procurement regulations or
practices could adversely affect the Company.

         The Company's business strategy is to continue to focus on higher-end
product-based solutions, to broaden its product offering, and to remain a
low-cost, and high-reliability provider of commodity products. The Company also
focuses on bringing new technologies to government customers.

Three Months Ended March 31, 2004 Compared
With the Three Months Ended March 31, 2003

         Sales. Sales consist of revenues from product shipments and services
rendered net of allowances for customer returns and credits. Revenues for the
first quarter of 2004 were relatively flat at $178.6 million, compared to $178.9
million in the first quarter of 2003. Open market sales are up $9.0 million or
33.4% for the quarter due in part to the increase in other vendors. The Company
continues to have new vendors come to GTSI for its expertise with government
procurement. In some cases, these new vendors will flow through as an open
market sale until programs teams have had time to determine which contracts, if
any, the vendor's product line best fits. Subcontracts and Other Contracts sales
increased $6.4 million or 30.0% due to increased volume of sales with prime
contractors and increased sales to state and local customers under the US
Communities Contract. The Company created a new Integrator Solution Group during
2003 that is focused on creating relationships with large system integrators
within the Government and private sectors. GSA schedules sales are down $9.7
million or 18.6% due to the expedition of two major Blanket Purchase Agreements
("BPAs"). Sales on IDIQ contracts are down $6.0 million or 7.6% for the quarter.

         Backlog. The Company recognizes an order in its backlog at the time it
receives and accepts a written customer purchase order. The Company's Total
Backlog includes orders that have not shipped ("Unshipped Backlog") as well as
orders that have shipped but not delivered at the period end. Total Backlog at
March 31, 2004 was approximately $98.0 million compared to $72.2 million at
March 31, 2003. Unshipped Backlog at March 31, 2004 was approximately $87.9
million compared to $65.1 million at March 31, 2003. Backlogs fluctuate
significantly from quarter to quarter because of the seasonality of Government
ordering patterns and fluctuations in inventory availability of various
products.

         Gross Margin. Gross margin is sales less cost of goods sold, which
includes product cost, freight, warranty maintenance cost and certain other
expenses related to the cost of acquiring products. Gross margin for the first
quarter 2004 increased $2.0 million to $18.1 million compared to $16.1 million
in the same quarter of 2003. The increase is primarily due to higher vendor
volume incentive payments. The Company continues to focus its sales efforts to
vendors that are offering these volume incentive programs and its sales force is
given incentives to sell these vendors products. Gross margin as a percentage of
total sales in the first quarter of 2004 increased to 10.1% of total sales from
9.0% of total sales in the same quarter of 2003. Gross margin percentages vary
over time and may change significantly depending on the mix of customer's use of
available contract vehicles and the mix of product sold.

         Operating Expenses. Total operating expenses for the three months ended
March 31, 2004 increased $2.0 million to $21.7 million from the same period in
2003. Expressed as a percentage of total sales, total operating expenses
increased to 12.1% from 11.0% in the same quarter last year. The increase in
operating expense was partially driven by increased outside services expenses
related to our SOX 404 efforts, our new ERP system implementation, and our "I
Rely on GTSI" marketing campaign.

         Interest and Other Income, Net. Net interest and other income in the
first quarter of 2004 increased to $1.3 million compared to $0.7 million in the
same period in 2003 due primarily to an increase in interest income from
equipment leases offset by a decrease in prompt payment discounts from vendors.
The Company continues to take advantage of prompt payment discounts when offered
by vendors. However, due to lower interest rates, the Company's vendors have
reduced their prompt payment programs.

         Income Tax. The Company recorded a tax benefit of $0.9 million for the
first quarter of 2004 based on the effective rate of approximately 39.5%
compared to a tax benefit of $1.1 million in the same period last year.

Effect of Inflation

         The Company believes that inflation has not had a material effect on
its operations. If, however, inflation increases in the future it could
temporarily adversely affect the profitability of GTSI's sales under its
government fixed-price contracts, which generally preclude the Company from
passing on inflation-related or other increases in product costs to Government
customers during the term of a pre-existing contract. The Company mitigates this
risk in part by often obtaining agreements from certain of its suppliers
prohibiting them from increasing their prices to GTSI during fixed-price, term
contracts.

Seasonal Fluctuations and Other Factors

         The Company has historically experienced and expects to continue to
experience significant seasonal fluctuations in its operations as a result of
government buying and funding patterns, which also affect the buying patterns of
GTSI's prime contractor customers. These buying and funding patterns
historically have had a significant positive effect on GTSI's bookings in the
third quarter ending September 30 each year (the federal government's fiscal
year end), and consequently on sales and net income in the third and fourth
quarters of each year. Quarterly financial results are also affected by the
timing of the award of and shipments of products under government contracts,
price competition in the computer and IT industries, the addition of personnel
or other expenses in anticipation of sales growth, product line changes and
expansions, and the timing and costs of changes in customer and product mix. In
addition, customer order deferrals in anticipation of new product releases by
leading hardware and software manufacturers, delays in vendor shipments of new
or existing products, a shift in sales mix to more complex requirements
contracts with more complex service costs, and vendor delays in the processing
of incentives and credits due GTSI, have occurred (all of which are also likely
to occur in the future) and have adversely affected the Company's operating
performance in particular periods. The seasonality and the unpredictability of
the factors affecting such seasonality make GTSI's quarterly and yearly
financial results difficult to predict and subject to significant fluctuation.
The Company's stock price could be adversely affected if any such financial
results fail to meet the financial community's expectations.

         Additionally, legislation is periodically introduced in Congress that
may change the federal government's procurement practices, and agencies from
time to time may issue new regulations or modify existing regulations that may
also change the government's procurement practices. GTSI cannot predict whether
any legislative or regulatory proposals will be adopted or, if adopted, the
impact upon its operating results. Changes in the structure, composition and/or
buying patterns of the Government, either alone or in combination with
competitive conditions or other factors, could adversely affect future results.

New Accounting Pronouncements

         In January 2003, the FASB issued Interpretation No. 46, "Consolidation
of Variable Interest Entities (FIN No. 46). FIN No. 46 clarifies the application
of Accounting Research Bulletin No. 51, "Consolidated Financial Statements", to
certain entities in which equity investors do not have the characteristics of a
controlling financial interest or do not have sufficient equity at risk for the
entity to finance its activities without additional subordinated financial
support from the other parties. FIN No. 46 applies to variable interest entities
created after January 31, 2003. The consolidation requirements apply to older
entities in the first fiscal year or interim period beginning after December 15,
2003, which is the Company's first quarter of fiscal year 2004. The Company has
adopted of FIN No. 46 with no material impact on its condensed consolidated
financial statements.

Liquidity and Capital Resources

         During the first three months of 2004, the Company's operating
activities provided $35.5 million of cash flow, compared to the $16.9 million of
cash flow provided during the same period in 2003. In the first quarter of the
year the Company's cash flow benefits from the change in the Company's revenue
seasonality. The main increase in operating cash flow was due to the increased
collections of accounts receivables during the first quarter.

         Investing activities used cash of approximately $1.9 million during the
three months ended March 31, 2004, compared to $2.2 million for the same period
in 2003 reflecting the Company's investment in software for a new fulfillment
system, intended to improve efficiency throughout the Company. As of March 31,
2004, the Company has capitalized approximately $5.8 million under this project.
The Company will continue to invest in this project throughout 2004.

         During the three months ended March 31, 2004, the Company's financing
activities used cash of approximately $12.3 million primarily to repay
borrowings under the Company's Credit Facilities.

         The Company has a $125 million credit facility with a group of banks
(the "Credit Facility"). The Credit Facility, which matures on February 28,
2005, includes a revolving line of credit (the "Revolver") and a provision for
inventory financing of vendor products (the "Wholesale Financing Facility").
Borrowing under the Revolver is limited to 85% of eligible accounts receivable.
The Revolver is secured by substantially all of the Company's assets. Borrowing
under the Wholesale Financing Facility is limited to 100% of the value of the
inventory. The Wholesale Financing Facility is secured by the underlying
inventory. The Credit Facility carries an interest rate indexed to LIBOR plus
1.75 percentage points. The Credit Facility also contains certain covenants as
well as provisions specifying compliance with certain quarterly and annual
financial ratios. At March 31, 2004, the Company was in compliance with all
financial covenants set forth in the Credit Facility and had additional
available credit on the Credit Facility of $70.3 million.

         The Company anticipates that it will continue to rely primarily on
operating cash flow, bank loans and vendor credit to finance its operating cash
needs. The Company believes that such funds should be sufficient to satisfy the
Company's near term anticipated cash requirements for operations. Nonetheless,
the Company may seek additional sources of capital, including permanent
financing over a longer term at fixed rates, to finance its working capital
requirements. The Company believes that such capital sources will be available
to it on acceptable terms, if needed.

Sarbanes-Oxley Section 404

         The Company is working to comply with the requirements set of Section
404 of the Sarbanes-Oxley Act. Under SOX 404, the Company is required to attest
to the effectiveness of its internal controls as of December 31, 2004. At this
time it is not clear as to the total cost the Company will incur as a result of
this compliance effort. During the first quarter of 2004, the Company expensed
approximately $0.1 million on this effort and expects cost to increase during
the second and subsequent quarters.

"Safe Harbor" Statement under the Private Securities Litigation Reform Act
of 1995

         Except for historical information, all of the statements, expectations,
beliefs, anticipations, intentions, and assumptions contained in the foregoing
material are "forward-looking statements" (within the meaning of the Private
Securities Litigation Reform Act of 1995, as amended) that involve a number of
risks and uncertainties. All such forward-looking statements are intended to be
subject to the safe harbor protection provided by the Private Securities Reform
Act of 1995, as amended, and by other applicable securities laws. It is possible
that the assumptions made by management -- including, but not limited to, those
relating to the cost of and compliance with Sarbanes-Oxley Section 404,
favorable gross margins, a favorable mix of contracts, benefits of a more
efficient operation, future contract awards, returns on new product programs,
profitability, recovery of the costs of inventory, and increased control of
operating costs -- may not materialize. Actual results may differ materially
from those projected or implied in any forward-looking statements. Readers are
cautioned not to place undue reliance on these forward-looking statements, which
reflect management's analysis only as of the date hereof. The Company undertakes
no obligation to revise publicly the forward-looking statements to reflect
events or circumstances that arise after the date hereof. Readers should
carefully review the risks factors described in other documents the Company
files from time to time with the Securities and Exchange Commission, including
the Quarterly Reports on the Form 10-Q and Annual Report on Form 10-K to be
filed by the Company subsequent to this Quarterly Report on Form 10-Q and any
Current Reports on Form 8-K filed by the Company.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company had a $125.0 million credit facility indexed at LIBOR plus
1.75 percentage points as of March 31, 2004. This variable rate credit facility
subjects the Company to potential borrowing costs exposure resulting from
changes in interest rates. In recent years, the Company has not borrowed such
significant amounts that any movement in interest rates has had a material
effect on its earnings or cash flows. Accordingly, at current borrowing levels,
the Company does not believe that any move in interest rates would have such an
effect. If the Company were to increase borrowings under its Credit Facility
significantly, then future interest rate changes could potentially have such a
material impact on earnings.

ITEM 4.  CONTROLS AND PROCEDURES

         (a) Evaluation of disclosure controls and procedures

         As of the end of the 90 day period covered by this report, the Company
carried out an evaluation of the effectiveness of the design and operation of
its disclosure controls and procedures pursuant to Exchange Act Rule 13a-15
under the supervision and with the participation of the Company's management,
including the Company's Chief Executive Officer and Chief Financial Officer.
Based upon that evaluation, the Company's Chief Executive Officer and Chief
Financial Officer concluded that that Company's disclosure controls and
procedures are effective. Disclosure controls and procedures are controls and
procedures that are designed to ensure that information required to be disclosed
in the Company's reports filed or submitted under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the
Securities and Exchange Commission's rules and forms.

         (b) Changes in internal controls

         There were no significant changes in our internal controls or in other
factors that could significantly affect our internal controls subsequent to the
Evaluation Date.

                           PART II - OTHER INFORMATION

ITEM 1.   LEGAL PROCEDURES

         In November 2003, GTSI was servied with a $25 million lawsuit, with
treble damages, related to the termination of a former subcontractor. This suit
follows the Company's earlier lawsuit against the former subcontractor.
Management believes those claims are without merit and intends to vigorously
defend this lawsuit, but the ultimate outcome of this matter is uncertain.
Management is unable to estimate the amount GTSI may have to pay related to this
matter. No amounts have been accrued as of March 31, 2004.
