                        INDEPENDENT AUDITOR'S REPORT


To the Board of Directors
Technical and Management Services Corporation
Calverton, Maryland

We have audited the accompanying consolidated balance sheet of Technical and
Management Services Corporation and subsidiaries (the Company) as of
December 31, 2002, and the related consolidated statement of income,
stockholders' equity and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based
on our audit.

We conducted our audit in accordance with auditing standards generally
accepted in the United States of America. 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
audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
Technical and Management Services Corporation and subsidiaries as of
December 31, 2002, and the results of their operations and their cash flows
for the year then ended in conformity with accounting principles generally
accepted in the United States of America.

TECHNICAL AND MANAGEMENT SERVICES CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
------------------------------------------------------------------------------

NOTE 1.    NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Nature of business: Technical and Management Services Corporation (the
------------------
Parent) and its subsidiaries (the Company), a Maryland corporation, is a
government contractor which provides primarily engineering and software
development services to the Federal government or to prime contractors of
the Federal government. The Company has a division which manufactures
engineering equipment for use by the Federal government. The Company's
majority-owned subsidiaries, Meridian Aquatic Technology L.L.C. and Marine
Environmental Solutions, L.L.C. (combined, Meridian) provide aquaculture and
biofiltration related products.

The Company is subject to all of the risks associated with conducting
business with the U.S. Federal government, including the risk of contract
terminations at the convenience of the government. In addition, government
funding continues to be dependent on congressional approval of program level
funding and on contract agency approval for the Company's work. The extent
to which the Company's existing contracts will be funded in the future
cannot be determined.

A summary of the Company's significant accounting policies follows:

Principles of consolidation: The accompanying consolidated financial
---------------------------
statements, include the accounts of the Company and its majority-owned
subsidiaries, Meridian and Log Systems, Inc. (LSI). As of December 31, 2002,
the Company owned approximately 80% of both subsidiaries. All material
inter-company transactions and balances have been eliminated in the
consolidation. The subsidiaries' equity deficit results in no minority
interest on the consolidated financial statements.

Revenue and cost recognition: The Company generates revenue under cost
----------------------------
reimbursable, time and material, and fixed price contracts. Revenue from
cost reimbursable contracts is recognized on the basis of reimbursable
contract costs incurred during the period increased by the applicable
fringe, overhead, and general and administrative expenses, plus the fee
earned. Revenue from fixed price contracts is recognized on the percentage
of completion basis. Under this method, contract revenue earned on
individual contracts is measured by the percentage relationship that
contract costs incurred bear to management's estimate of total contract
costs. Revenue from time and material contracts is recognized on the basis
of man-hours utilized, plus other reimbursable contract costs incurred
during the period.

A provision for estimated losses on uncompleted contracts is made in the
period in which such losses are determined. Change in job performance, job
conditions and estimated profitability may result in revisions to costs and
revenue, and are recognized in the period in which the revisions are
determined.

The Company recognizes revenue under its U.S. Federal government contracts
when a contract has been executed, the contract price is fixed and
determinable, delivery of the services or products has occurred, and
collectibility of the contract price is considered probable. The Company's
contracts with agencies of the U.S. Federal government are subject to
periodic funding by the respective contracting agency. Funding for a
contract may be provided in full at inception of the contract or ratably
throughout the contract as the services are provided. In evaluating the
probability of funding for purposes of assessing collectibility of the
contract price, the Company considers its previous experiences with the
customers, communications with the customers regarding funding status, and
the Company's knowledge of available funding to the contract or program. If
funding is not assessed as probable, revenue recognition is deferred until
realization is probable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
------------------------------------------------------------------------------

NOTE 1.    NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Contract receivables: In accordance with industry practice, contract
--------------------
receivables relating to long-term contracts are classified as current, even
though a portion of these amounts are not expected to be realized within one
year.

Billed accounts receivable are carried at the amounts invoiced less an
estimate made for doubtful accounts based on a review of all outstanding
amounts on a monthly basis. Management determines the allowance for doubtful
accounts by identifying troubled accounts and using historical experience
with the customer and evaluating the customer's funding history. Billed
accounts receivable are considered past due if the invoice has been
outstanding more than 30 days. The Company does not charge interest on
accounts receivables, however, U.S. governmental agencies pay interest on
invoices outstanding more than 30 days. The Company records interest income
from U.S. governmental agencies when received. An allowance in the amount of
$240,000 at December 31, 2002, is made against receivables included with
assets from discontinued operations. Management believes that receivables
from continuing operations are fully collectible and no allowance is
necessary.

Unbilled accounts receivable consist primarily of costs incurred and accrued
fees in excess of billings and rate variances on certain cost reimbursable
contracts and are normally due within one year. These amounts will be billed
on the basis of contract terms and delivery schedules.

Both billed and unbilled receivables are written off when deemed
uncollectible. Recoveries of receivables previously written off are recorded
when received.

Inventory: Inventory is valued at the lower of cost or market, with cost
---------
determined using the average cost method. Inventory, which is included with
assets from discontinued operations, as of December 31, 2002, consists of
raw materials of $87,207, and finished goods, net of an allowance, of
$58,179. The allowance against finished goods was estimated at $287,000 at
December 31, 2002. Finished goods include an allocation of direct and
indirect costs of production.

Property and equipment: Property and equipment are stated at cost.
----------------------
Depreciation is calculated and amortized over the estimated useful lives of
the assets using accelerated and straight-line methods.

Income taxes: The Company has elected to be treated as an S-Corporation
------------
under Subchapter S of the Internal Revenue Code. Consequently, the Company
is not liable for Federal and state income taxes, except for certain states
not recognizing the S-Corporation status. Except for those states, the
stockholders, not the Company, will be liable for income taxes on the
Company's income.

Deferred income taxes for certain states are provided on a liability method,
whereby, deferred tax assets are recognized for deductible temporary
differences and operating loss and tax carryforwards, and deferred tax
liabilities are recognized for taxable temporary differences. Temporary
differences are the differences between the reported amounts of assets and
liabilities and their tax basis. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely
than not that some portion or all of the deferred tax assets will not be
realized. Deferred tax assets and liabilities are adjusted for the effects
of changes in tax laws and rates on the date of enactment.

NOTE 1.    NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


Estimates: The preparation of financial statements 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 revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

Financial credit risk: Substantially all of the Company's contract
---------------------

December 31, 2002, was $2,260,977.

NOTE 14.    DISCONTINUED OPERATIONS

During the year ended December 31, 2002, the Company's management and owners
have committed to plans to sell their majority-owned subsidiaries, Meridian
Aquatic Technology L.L.C. and Marine Environmental Solutions, L.L.C.
(combined, Meridian). Meridian is available for immediate sale in its
present condition and there is an active program to locate a buyer. Meridian
is being actively marketed for sale at a price that is reasonable in
relation to its current market value. Management feels that the sale of
Meridian is probable within one year and represent that it is unlikely that
significant changes to the plan will be made or that the plan will be
withdrawn. In the event that a suitable buyer is not identified within one
year, the owners and management have committed to shut down the
subsidiaries' operations. In the circumstance of a sale of Meridian, the
operations and cash flows of the subsidiaries will be eliminated from the
ongoing operations of the Company and the Company will not have any
significant continuing involvement in the operations of Meridian after the
sale transaction except within the ordinary course of business.

NOTE 15.    CONTINGENCIES

Contract costs, including indirect costs, are subject to audit by agencies
of the U.S. Government. Upon certification of final audited costs,
applicable unbilled contract costs are adjusted to reflect the amounts due
to or from the government and are billed.

The Company's indirect cost rates have been audited and approved for 1997
and prior years. Management believes that the audits of the indirect cost
rates for 1998 through 2002 will not result in material adjustments, if any,
to the Company's results of operations or financial position. As such, no
provision has been made in the financial statements for any adjustments that
may result from the audits.

The Company has disputed a claim made by a taxation authority. The Company
has retained legal counsel and has vigorously protested the claims made.
Legal counsel believes that the outcome could result in a potential
liability up to approximately $112,000 plus interest computed at 15% per
year. The amount of the liability, if any, could not presently be
determined.

NOTE 16.    SALE OF COMPANY

On February 18, 2003, the Company signed a letter of intent to sell 100% of
the outstanding common stock. On May 1, 2003, Engineered Support Systems,
Inc. acquired the outstanding stock of the Company.

Item 7 (b) (2) - Notes to Pro Forma Condensed Statements of Income (Unaudited)
                 for the year Ended October 31, 2002









Engineered Support Systems, Inc.
Pro Forma Condensed Statements of Income (Unaudited)
For the Year Ended October 31, 2002
(In thousands, except per share amounts)

Note A - Basis of Presentation

On May 1, 2003, Engineered Support Systems, Inc. (the Company) acquired the
outstanding stock of Technical and Management Services Corporation (TAMSCO),
a provider of information technology logistics and digitization services and
a designer and integrator of telecommunications systems primarily for the
U.S. Department of Defense. The purchase price including acquisition costs,
net of $146 cash acquired, of $64.7 million was financed with an unsecured
revolving credit facility as provided for under the terms of a new credit
agreement dated April 23, 2003.

The unaudited pro forma condensed statements of income for the year ended
October 31, 2002 present a combination of the historical statements of
income for the Company and TAMSCO as adjusted to reflect the purchase
transaction in accordance with the purchase method of accounting and to
reflect an income tax provision for TAMSCO as if it were filing on a
consolidated basis with the Company under the provisions of the Internal
Revenue Code for the year ended October 31, 2002. A pro forma condensed
statement of income is presented for the year ended October 31, 2002 as if
the acquisition had occurred as of November 1, 2001.

The pro forma condensed statement of income for the year ended October 31,
2002 includes the Company's results of operations for the year ended October
31, 2002 and TAMSCO's audited results of operations for the year ended
December 31, 2002. The historical statement of income for TAMSCO does not
include the discontinued operations of its majority-owned subsidiaries,
Meridian Aquatic Technology L.L.C. and Marine Environmental Solutions
L.L.C., which are excluded from the purchase transaction. In addition,
direct expenses and operating expenses as presented in TAMSCO's audited
results for the year ended December 31, 2002 have been reclassified as cost
of revenues and selling, general and administrative expense in the pro forma
condensed statements of income in order to conform to ESSI's historical
presentation.

The unaudited pro forma results are not necessarily indicative of the
combined results that would have occurred had the acquisition actually taken
place on November 1, 2001, nor are they necessarily indicative of the
results that may occur in the future. The pro forma financial statements
should be read in conjunction with the related historical financial
statements.








Note B - Income Taxes

Pro forma adjustments to the condensed statements of income include an
income tax provision as if TAMSCO had filed on a consolidated basis with the
Company for the period presented using the Company's historical effective
tax rate of 39%.

Note C - Pro Forma Adjustments

The purchase price, including acquisition costs and less cash acquired of
$146, was $64,717. The purchase price for TAMSCO was allocated as follows:

         Estimated fair value of TAMSCO assets                      $  38,069
         Estimated fair value of TAMSCO liabilities                    33,377
                                                                    ---------
         Estimated fair value of TAMSCO net assets                      4,692
         Deferred income tax liability not assumed                        640
                                                                    ---------
         Estimated fair value of TAMSCO net asset acquired              5,332
         Cost in excess of net assets acquired                         59,531
                                                                    ---------
                                                                       64,863
         Cash acquired                                                    146
                                                                    ---------
         Purchase price, net of cash acquired                       $  64,717
                                                                    =========

The tax basis of the acquired assets and liabilities equals the financial
statement values as a result of the Company's tax election to treat the
stock purchase as an asset purchase.

Pro forma adjustments to the condensed pro forma income statement for the
year ended October 31, 2002 relate to the following items. Selling, general
and administrative expense has been increased by $58 for the amortization of
loan fees (over a 4-year period).

Concurrent with the acquisition, the company entered into a new credit
agreement with various financial institutions. This agreement provides for a
$125 million revolving credit facility with an option for the Company to
increase borrowings under the facility to $200 million. Effective borrowing
rates under the new credit agreement are lower than historical borrowing
rates for the year ended October 31, 2002. As a result of the acquisition,
net interest expense has been increased by $712 for the year ended October
31, 2002. The effect on net income of a 1/8% variance in interest rates is
$92 for the year ended October 31, 2002.

The income tax provision has been adjusted to reflect the estimated income
tax effects of pro forma adjustments and the effect of reflecting income tax
for TAMSCO as described in Note B. These adjustments to the pro forma income
statements were computed assuming the transaction was consummated at the
beginning of the period presented.

Item 7 (b) (5) - Notes to Pro Forma Condensed Financial Statements (Unaudited)
                 for the six months ended April 30, 2003








Engineered Support Systems, Inc.
Pro Forma Condensed Statements of Income (Unaudited)
For the Six Months Ended April 30, 2003
(In thousands, except per share amounts)

Note A - Basis of Presentation

On May 1, 2003, Engineered Support Systems, Inc. (the Company) acquired the
outstanding stock of Technical and Management Services Corporation (TAMSCO),
a provider of information technology logistics and digitization services and
a designer and integrator of telecommunications systems primarily for the
U.S. Department of Defense. The purchase price including acquisition costs,
net of $146 cash acquired, of $64.7 million was financed with an unsecured
revolving credit facility as provided for under the terms of a new credit
agreement dated April 23, 2003.

The unaudited pro forma condensed statements of income for the six months
ended April 30, 2003 present a combination of the historical statements of
income for the Company and TAMSCO as adjusted to reflect the purchase
transaction in accordance with the purchase method of accounting and to
reflect an income tax provision for TAMSCO as if it were filing on a
consolidated basis with the Company under the provisions of the Internal
Revenue Code for the year ended October 31, 2002. A pro forma condensed
statement of income is presented for the six months ended April 30, 2003 as
if the acquisition had occurred as of November 1, 2001.

The pro forma condensed statements of income for the six months ended April
30, 2003 include the unaudited results of operations for the Company and
TAMSCO for this period. A pro forma condensed consolidated balance sheet is
presented as of April 30, 2003, which includes the TAMSCO balance sheet as
of that date. The historical statements of income and the balance sheet for
TAMSCO do not include the discontinued operations of its majority owned
subsidiaries, Meridian Aquatic Technology L.L.C. and Marine Environmental
Solutions L.L.C., which are excluded from the purchase transaction. In order
to compile the results of operations and balance sheet for TAMSCO for the
six months ended April 30, 2003, a detailed review of TAMSCO's internal
accounting records was performed.

The unaudited pro forma results are not necessarily indicative of the
combined results that would have occurred had the acquisition actually taken
place on November 1, 2001, nor are they necessarily indicative of the
results that may occur in the future. The pro forma financial statements
should be read in conjunction with the related historical financial
statements.

Note B - Income Taxes

Pro forma adjustments to the condensed statements of income include an
income tax provision as if TAMSCO had filed on a consolidated basis with the
Company for the period presented using the Company's historical effective
tax rate of 39%.








Note C - Pro Forma Adjustments for Six Month Statements of Income

The purchase price, including acquisition costs and less cash acquired of
$146, was $64,717. The purchase price for TAMSCO was allocated as follows:

         Estimated fair value of TAMSCO assets                        $  38,069
         Estimated fair value of TAMSCO liabilities                      33,377
                                                                      ---------
         Estimated fair value of TAMSCO assets                            4,692
         Deferred income tax liability not assumed                          640
                                                                      ---------
         Estimated fair value of TAMSCO net assets acquired               5,332
         Cost in excess of net assets acquired                           59,531
                                                                      ---------
                                                                         64,863
         Cash acquired                                                      146
                                                                      ---------
         Purchase price, net of cash acquired                         $  64,717
                                                                      =========

The tax basis of the acquired assets and liabilities equals the financial
statement values as a result of the Company's tax election to treat the
stock purchase as an asset purchase.

Pro forma adjustments to the condensed pro forma income statement for the
six months ended April 30, 2003 relate to the following items. Selling,
general and administrative expense has been increased by $19 for the
amortization of loan fees (over a 4-year period).

Concurrent with the acquisition, the company entered into a new credit
agreement with various financial institutions. This agreement provides for a
$125 million revolving credit facility with an option for the Company to
increase borrowings under the facility to $200 million. Effective borrowing
rates under the new credit agreement are higher than historical borrowing
rates for the six months ended April 30, 2003. As a result of the
acquisition, net interest expense has been increased by $707 for the six
months ended April 30, 2003. The effect on net income of a 1/8% variance in
interest rates is $37 for the six months ended April 30, 2003.

The income tax provision has been adjusted to reflect the estimated income
tax effects of pro forma adjustments and the effect of reflecting income tax
for TAMSCO as described in Note B. These adjustments to the pro forma income
statements were computed assuming the transaction was consummated at the
beginning of the period presented.

Note D - Balance Sheet Purchase Accounting Adjustments

Included in the April 30, 2003 pro forma condensed consolidated balance
sheet is a purchase accounting adjustment for cost in excess of net assets
acquired of $59,531. The Company has not completed its evaluation of the
fair value of identifiable intangible assets and has included total cost in
excess of net assets acquired in goodwill on the April 30, 2003 pro forma
condensed consolidated balance sheet. Additional purchase accounting
adjustments to the pro forma condensed consolidated balance sheet include a
$53,671 increase in notes payable and a $14,000 decrease in cash and cash
equivalents necessary to finance the acquisition and to retire $812 in
TAMSCO term debt. A receivable from the sellers of $1,996 has been
established related to certain estimated purchase price adjustments as set
forth in the final purchase agreement. Deferred income taxes related to
TAMSCO in the amount of $640 will not be assumed by Company.
