                   SENSYS TECHNOLOGIES INC. AND SUBSIDIARIES

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


1.  BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information for commercial and industrial companies and with the
instructions to Form 10-QSB and Rule 10-01 of Regulation S-X. Accordingly, they
do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for fair presentation have been included.
Operating results for the three and six month periods ended March 31, 1999 are
not necessarily indicative of the results that may be expected for the fiscal
year ending September 30, 1999. Intercompany accounts and transactions have
been eliminated in consolidation. For further information, refer to Sensys
Technologies Inc.'s Annual Report on Form 10-KSB for the year ended September
30, 1998.

2.   ACQUISITION

On June 9, 1998, Daedalus Enterprises, Inc. ("DEI") merged with S. T. Research
Corporation ("STR"). In connection with the merger, DEI changed its name to
Sensys Technologies Inc. (the "Company"). While DEI was the legal acquiror, the
merger was accounted for as a reverse acquisition purchase whereby STR was
deemed to have acquired DEI for financial reporting purposes. Consistent with
the reverse acquisition accounting treatment, the historical financial
statements presented for periods prior to the merger date are the financial
statements of STR except for stockholders' equity which has been retroactively
restated for the equivalent number of shares of the legal acquiror. An
adjustment has also been made to adjust the par value of the outstanding shares
with an offset to additional paid-in capital. Because of the accounting
treatment herein described, the financial statements differ from the
consolidated financial statements of DEI as previously reported. The operations
of DEI have been included in the financial statements commencing on the date of
the merger. In connection with the merger, the Company changed its fiscal
year-end from July 31 to September 30.

3.   INVENTORIES

Inventories are valued at the lower of cost or market using the first-in,
first-out method and consisted of the following:

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                                  (CONTINUED)

4.   STOCK OPTIONS

On October 5, 1998, the Compensation Committee of the Board of Directors
approved the award of 414,000 options to employees at a fair market value price
of $3.00 per share. As of March 31, 1999, 31,000 of these options had been
forfeited.

5.   PROPERTY HELD FOR SALE

At September 30, 1998, property held for sale consisted of land and a building
acquired in connection with the merger with DEI. On December 1, 1998, the
Company sold the property for cash of approximately $1,575,000, with net
proceeds of approximately $1,446,000 of which approximately $220,000 was used
to pay off the existing mortgage balance. Under terms of the sales agreement,
the Company is leasing approximately fifty percent of the facility for five
years with a five year option. The annual rental approximates $112,000 for each
of the next five years for an aggregate amount of $560,000.

6.   NOTE PAYABLE - LINE OF CREDIT

Effective February 28, 1999, the Company entered into a line of credit and
related note payable with its bank. The agreement expires February 28, 2001,
and provides a maximum available line of credit of $3,000,000. However, the
total borrowing base generally cannot exceed the sum of 90 percent of qualified
Government accounts receivable and 80 percent of qualified non-Government
accounts receivable. The bank agreement establishes the interest rate at the
LIBOR rate (5.0 percent at March 31, 1999) plus 225 to 300 basis points,
determined by the Company's ratio of funded debt to earnings before interest,
taxes, depreciation and amortization. All borrowings under the line of credit
and the performance of the Company's obligations under the line of credit
agreement are secured by the Company's accounts receivable, equipment,
contracts, and general intangibles. The agreement also contains various
covenants as to dividend restrictions, working capital, tangible net worth,
earnings and debt-to-equity ratios. As of March 31, 1999, no amounts were
outstanding. Unused commitment fees of one quarter of one percent per annum are
required.

7.   EARNINGS PER SHARE

The computation of net earnings per share is based on the weighted average
number of shares of common stock outstanding during the periods presented. The
weighted average number of shares used in the basic earnings per share
calculation was 3,968,554 and 2,920,065 for the three month periods ended March
31, 1999 and 1998, respectively, and 3,967,576 and 2,387,932 for the six month
periods ended March 31, 1999 and 1998, respectively. The weighted average
number of shares used in the diluted earnings per share calculation was
4,177,764 and 2,950,242 for the three month periods ended March 31, 1999 and
1998, respectively. The weighted average number of shares used in the diluted
earnings per share calculation was 4,159,775 and 2,429,365 for the six month
periods ended March 31, 1999 and 1998, respectively.

8.   NEW ACCOUNTING PRONOUNCEMENTS

On June 15, 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS No. 133 establishes a new
model for accounting for derivatives and hedging. The new standard


                                       10

<PAGE>   11

requires enhanced disclosure of accounting policies for derivative financial
instruments and derivative commodity instruments in the footnotes to the
financial statements. In addition, the standard expands disclosure requirements
to include quantitative and qualitative information about market risk inherent
in market risk sensitive instruments.

The Company will adopt SFAS No. 133 effective October 1, 1999. The Company
believes that the adoption of this statement will not have a material effect on
the Company's consolidated financial position or results of operations.

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

The following discussion provides information which management believes is
relevant to an assessment and understanding of the Company's operations and
financial condition. This discussion should be read in conjunction with the
condensed consolidated financial statements and accompanying notes.

Forward-looking Statements

        Certain statements made by the Company's management may be considered
to be "forward-looking statements" within the meaning of the Private Securities
Litigation Act of 1995. Forward-looking statements are based on various factors
and assumptions that include known and unknown risks and uncertainties. The
words "believe", "expect", "anticipate" and "project" and similar expressions
identify forward-looking statements, which speak only as of the date the
statement was made. Such statements may include, but not be limited to,
projections of revenues, income or loss, expenses, plans, as well as
assumptions relating to the foregoing. Forward-looking statements are
inherently subject to risks and uncertainties, some of which cannot be
predicted or quantified, including, but not limited to the size and timing of
orders and shipments, changes in economic conditions, the cost of labor and raw
materials, changes in technology and general competitive factors. The Company
undertakes no obligation and does not intend to update, revise or otherwise
publicly release the results of any revisions to these forward-looking
statements that may be made to reflect future events or circumstances.

GENERAL OVERVIEW

The Company designs, develops and manufactures systems and equipment used for
electronic reconnaissance and imaging. Through its electronic reconnaissance
efforts, the Company supports telecommunications intelligence, signal
intelligence, electronic support measures, electronic intelligence and airborne
remote sensing initiatives of the defense and intelligence communities. The
Company's activities in airborne imaging principally relate to the manufacture
of airborne imaging systems which are installed in aircraft and are used to
acquire optical radiation data from objects on the earth's surface and in the
atmosphere.

On June 9, 1998, Daedalus Enterprises, Inc. ("DEI") merged with S. T. Research
Corporation ("STR"). In connection with the merger, DEI changed its name to
Sensys Technologies Inc. (the "Company"). The merger was accounted for as a
reverse acquisition purchase whereby STR was deemed to have acquired DEI for
financial reporting purposes. Consistent with the reverse acquisition
accounting treatment, the historical financial statements presented for periods
prior to the merger date are the financial statements of STR except for
stockholders' equity which has been retroactively restated for the equivalent
number of shares of the legal acquiror. An adjustment has also been made to
adjust the par value of the outstanding shares with an offset to additional
paid-in capital. Because of the accounting treatment herein described, the
financial statements differ

                                       11

from the consolidated financial statements of DEI as previously reported. The
operations of DEI have been included in the financial statements commencing on
the date of the merger. In connection with the merger, the Company changed its
fiscal year-end from July 31 to September 30.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31,
1998:

Revenue for the three months ended March 31, 1999 was $7,515,000 compared to
$6,502,000 for the three months ended March 31, 1998, resulting in a $1,013,000
or a 15.6% increase. The increase was primarily the result of additional
revenues of approximately $257,000 from the former DEI business and revenue
from an engineering development subcontract that started in the fourth quarter
of fiscal year 1998.

Cost of revenue, as a percentage of revenue, decreased from 84.7% for the three
months ended March 31, 1998 to 74.4% for the three months ended March 31, 1999.
The decrease primarily resulted from a reduction in revenue from contracts in
which losses were sustained and lower profit margins were realized, as well as
an overall increase in the profit margins under other contracts. The Company
attributes this improvement to focusing the business and streamlining the
operations for higher productivity.

For the three months ended March 31, 1999, general and administrative expenses
increased from $787,000 to $1,225,000 or a 55.7% increase compared to the three
month period ended March 31, 1998. The increase was due principally to an
overall increase in its traditional general and administrative expenses of
approximately $125,000, and Bid & Proposal/Independent Research and Development
(B&P/IR&D) expenses of $185,000 incurred by the acquired DEI business
activities. In addition, incentive compensation benefits increased
approximately $45,000 and expenses of approximately $100,000 were incurred
related to meeting the Company's obligations as a public company, which were
offset by a reduction in bad debt expense of $105,000. Goodwill amortization,
as a result of the DEI acquisition, accounted for approximately $17,000 of the
increase.

Interest expense decreased from $45,000 for the three months ended March 31,
1998 to $24,000 for the three months ended March 31, 1999, which represents a
46.7% decrease. The decrease was principally the result of lower average
borrowings. For the three months ended March 31, 1999, the Company was able to
utilize its improved operating performance and the net proceeds from the sale
of real estate on December 1, 1998, to reduce to zero, at March 31, 1999, its
outstanding balance on its line of credit.

Income tax expense consists of federal and state income tax. The Company's
effective tax rate was 38.5% for the three months ended March 31, 1999,
compared to an effective tax rate of 37.7% for the three months ended March 31,
1998. The principal cause of the change is non-deductible goodwill amortization
in 1999 recorded in association with the Company's merger with DEI and the
impact of marginal tax bracket for lower taxable income in fiscal year 1998.

Net income for the three months ended March 31, 1999 increased to $415,000,
compared to a net income of $101,000 for the three months ended March 31, 1998.
The increase of $314,000 was the result of the items discussed above.

The total amount of funded contracts in backlog as of March 31, 1999 and March
31, 1998 was $12,100,000 and $10,300,000, respectively, including both the
uncompleted portion of contracts in progress and contracts awarded but not yet
started. The funded contract backlog at March 31, 1999 is expected to be
completed


                                       12

within a year.

In addition, at March 31, 1999, the Company had an unfunded backlog of
$4,900,000 compared to an unfunded backlog of $416,000 at March 31, 1998.

Exercisable options for subsequent production under existing contracts are
approximately $44,000,000 at March 31, 1999, compared to $8,400,000 at March
31, 1998.The outstanding options at March 31, 1999 are primarily related to a
first tier subcontract for engineering and production of components of the
AIEWS systems for U.S. Navy surface ships. The Company currently anticipates
that the options will be exercised during the period 2001 through 2005.

SIX MONTHS ENDED MARCH 31, 1999 COMPARED TO SIX MONTHS ENDED MARCH 31, 1998:

Revenue for the six months ended March 31, 1999 was $13,538,000 compared to
$12,340,000 for the six months ended March 31, 1998, resulting in a $1,198,000
or 9.7% increase. The increase was primarily the result of additional revenues
of approximately $650,000 from the former DEI business and revenue from an
engineering development subcontract that started in the fourth quarter of
fiscal year 1998.

Cost of revenue, as a percentage of revenue, decreased from 86.3% for the six
months ended March 31, 1998 to 75.5% for the six months ended March 31, 1999.
The decrease primarily resulted from a reduction in revenue from contracts on
which losses were sustained and contracts on which lower margins were realized, 
as well as an overall increase in the profit margins under other contracts. The
Company attributes its improvement to focusing the business and streamlining
the operations for higher productivity.

For the six months ended March 31, 1999, general and administrative expenses
increased from $1,497,000 to $2,116,000 or a 41.3% increase compared to the
six-month period ended March 31, 1998. The increase was due principally to an
overall increase in traditional general and administrative expenses of $210,000
and Bid & Proposal/Independent Research & Development expenses of $240,000,
incurred by the acquired DEI business activities. In addition, incentive
compensation benefits increased approximately $115,000 and expenses of
approximately $125,000 were incurred related to meeting the Company's
obligations as a public company, which were offset by a reduction in bad debt
expense of $135,000. Goodwill amortization, as a result of the DEI acquisition,
accounted for approximately $35,000 of this increase.

Interest expense decreased from $148,000 for the six months ended March 31,
1998 to $70,000, a decrease of 52.7%, for the six months ended March 31, 1999.
The decrease is the result of lower average borrowings by the Company. In
January 1998, the Company's private placement generated $3,783,000 which was
used to pay down the line of credit. During the six month period ended March
31, 1999, the Company used its improved operating performance and the net
proceeds from the sale of real estate on December 1, 1998, to reduce to zero,
at March 31, 1999, its outstanding balance on its line of credit.

Income tax expense consists of federal and state income tax. The Company's
effective tax rate was 38.9% for the six months ended March 31, 1999, compared
to an effective tax rate of 37.3% for the six months ended March 31, 1998. The
principal cause of the change is the nondeductible goodwill amortization in
1999 recorded in association with the Company's merger with DEI and the impact
of the marginal tax bracket on the lower taxable income in fiscal year 1998.

Net income for the six months ended March 31, 1999 increased to $691,000,
compared to a net income of $32,000 for the six months ended March 31, 1998.
The increase of $659,000 was the result of the items discussed above.

LIQUIDITY AND SOURCES OF CAPITAL

At March 31, 1999, the Company's cash and cash equivalents totaled $849,000 as
compared to $112,000 at September 30, 1998. During the six-month period ended
March 31, 1999, the net cash provided to the company by its operating
activities was $1,797,000, as compared to $162,000 for the first six months of
fiscal year 1998, an increase of $1,635,000.

The net cash provided to the Company by its investing activities during the
six-month period ended March 31, 1999 was $1,209,000, as compared to cash used
for investing activities of $166,000 during the first six months of fiscal year
1998. This increase is attributable to the realization of net proceeds from the
sale of the real estate sold on December 1, 1998 of $1,446,000, and the
Company's acquisition of property and equipment during the six months ended
March 31, 1999 for $237,000. The Company anticipates that it will continue to
incur capital expenditures at this approximate rate through the end of the
fourth quarter of fiscal year 1999.

The net cash used by the Company in financing activities during the six month
period ended March 31, 1999 was $2,269,000, compared to net cash provided by
financing activities of $5,000 during the comparable six month period of fiscal
year 1998. For the six month period ended March 31, 1999, the net cash used was
primarily devoted to reducing to zero the Company's line of credit and
satisfying the mortgage on the real estate which was sold. The generation of
cash during the 1998 period is attributable to the Company's private placement
of common stock that occurred in January 1998, the proceeds of which were
$3,783,000. The proceeds of the placement were primarily used to satisfy
outstanding obligations of the Company.

The Company believes that cash on hand, anticipated cash flows from 1999
operations and amounts available for borrowing under its line of credit will be
sufficient to meet its working capital needs through the next twelve months.

NEW ACCOUNTING PRONOUNCEMENTS

On June 15, 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS No. 133 establishes a new
model for accounting for derivatives and hedging. The new standard requires
enhanced disclosure of accounting policies for derivative financial instruments
and derivative commodity instruments in the footnotes to the financial
statements. In addition, the standard expands disclosure requirements to
include quantitative and qualitative information about market risk inherent in
market risk sensitive instruments.

The Company will adopt SFAS No. 133 effective October 1, 1999. The Company
believes that the adoption of this statement will not have a material effect on
the Company's consolidated financial position or results of operations.

IMPLICATIONS OF YEAR 2000

The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the Company's
internal business systems, facilities and products that have software, whether
installed or embedded, may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in a system failure or miscalculations
causing disruptions of operations, including among, other things, a temporary
inability to process transactions, send invoices, or engage in


                                       14

<PAGE>   15

similar normal business activities. In addition, disruptions in the economy
generally resulting from Year 2000 issues could have a material adverse affect
on the Company.

The Company began its assessment of the implications of the Year 2000 issue
during March 1998, by developing plans and a program to address the potential
impact of the Year 2000 on its internal business systems, facilities and
products which might include embedded software. The Company has substantially
completed its review of each of these areas for potential Year 2000 impact.
Based on current information, the Company believes there are no material
operational problems or expenses related to the Year 2000 problem. Certain
versions of the Company's products require modifications and it appears there
may be opportunities to sell upgrades to its customer base. The Company does
not believe that it has any contingent liabilities associated with any products
it has previously manufactured which may not be Year 2000 fully compliant.
Detailed implementation plans are in place for the required modifications or
replacements. Products currently in production have been determined to be Year
2000 compliant and require no remediation. While initial assessments of Year
2000 implications are substantially complete, the Company plans to continually
re-assess its software-embedded products and operational software applications
to insure Year 2000 compliance. In addition, the Company has gathered
information about the Year 2000 compliance status of its significant suppliers,
vendors and subcontractors and continues to monitor their compliance. There
have been no significant compliance issues identified. The Year 2000 review
process and progress are monitored on a regular basis by a special task group
of management. There appears to be no material financial risk to the Company.

The Company has contingency plans for certain critical applications. Such plans
include, among other actions, manual workarounds, increasing inventories and
adjusting staffing strategies.

        Section 2.1  The Revolving Credit Facility.

                     2.1.1  Revolving Credit Facility.

                     Subject to and upon the provisions of this Agreement, the
Lender establishes a revolving credit facility in favor of the Borrower. The
aggregate of all advances under the Revolving Credit Facility is sometimes
referred to in this Agreement as the "Revolving Loan".

                     The principal amount of Three Million Dollars ($3,000,000)
is the "Revolving Credit Committed Amount".  If at any time the unpaid
principal balance of the


                                       16

<PAGE>   24


Revolving Loan exceeds the Revolving Credit Committed Amount in effect from
time to time, the Borrower shall pay such excess to the Lender ON DEMAND.

                    During the Revolving Credit Commitment Period, the Lender
agrees to make advances under the Revolving Loan requested by the Borrower from
time to time provided that after giving effect to the Borrower's request, the
outstanding principal balance of the Revolving Loan and of the Letter of Credit
Obligations would not exceed the lesser of (a) the Revolving Credit Committed
Amount, or (b) the then most current Borrowing Base.

                    Unless sooner paid, the unpaid Revolving Loan, together
with interest accrued and unpaid thereon, and all other Obligations shall be
due and payable in full on the Revolving Credit Expiration Date.

                    2.1.2   Procedure for Making Advances Under the Revolving
Loan; Lender Protection Loans.

                    The Borrower may borrow under the Revolving Credit
Commitment on any Business Day. Advances under the Revolving Loan shall be
deposited to a demand deposit account of the Borrower with the Lender (or an
Affiliate of the Lender) or shall be otherwise applied as directed by the
Borrower, which direction the Lender may require to be in writing. No later
than 10:00 a.m. (Baltimore time) on the date of the requested borrowing, the
Borrower shall give the Lender oral or written notice (a "Loan Notice") of the
amount and (if requested by the Lender) the purpose of the requested borrowing.
Any oral Loan Notice shall be confirmed in writing by the Borrower within three
(3) Business Days after the making of the requested Revolving Loan. In
addition, the Borrower hereby irrevocably authorizes the Lender at any time and
from time to time, without further request from or notice to the Borrower, to
make advances under the Revolving Loan which the Lender, in its sole and
absolute discretion, deems necessary or appropriate to protect the Lender's
interests under this Agreement, including, without limitation, advances under
the Revolving Loan made to cover debit balances in the Revolving Loan Account,
principal of, and/or interest on, any Loan, any of the Obligations, and/or
Enforcement Costs, prior to, on, or after the termination of other advances
under this Agreement, regardless of whether the outstanding principal amount of
the Revolving Loan which the Lender may make hereunder exceeds the Revolving
Credit Committed Amount.

                    2.1.3   Borrowing Base.

                    As used in this Agreement, the term "Borrowing Base" means
at any time, an amount equal to the aggregate of (a) ninety percent (90%) of
the amount of Eligible Receivables derived from Government Contracts, (b)
eighty percent (80%) of the amount of Eligible Receivables derived from
contracts other than Government Contracts approved by the Lender and (c) ninety
percent (90%) of the Borrower's foreign Eligible Receivables that are supported
by a letter of credit from a financial institution acceptable to the Lender.

                    The Borrowing Base shall be computed based on the Borrowing
Base Report most recently delivered to, and accepted by, the Lender in its sole
and absolute discretion. In the event the Borrower shall fail to furnish a
Borrowing Base Report required by Section 2.1.4 (Borrowing Base Report), or in
the event the Lender believes that a Borrowing Base Report is no


                                       17

<PAGE>   25


longer accurate, the Lender may, in its sole and absolute discretion exercised
from time to time and without limiting its other rights and remedies under this
Agreement, suspend the making of or limit advances under the Revolving Loan.
The Borrowing Base shall be subject to reduction by amounts credited to the
Collateral Account since the date of the most recent Borrowing Base Report and
by the amount of any Receivable which was included in the Borrowing Base but
which the Lender determines fails to meet the respective criteria applicable
from time to time for Eligible Receivables.

                    If at any time the total of the aggregate principal amount
of the Revolving Loan and Outstanding Letter of Credit Obligations exceeds the
Borrowing Base, a borrowing base deficiency ("Borrowing Base Deficiency") shall
exist. Each time a Borrowing Base Deficiency exists, the Borrower, at the sole
and absolute discretion of the Lender exercised from time to time, shall pay
the Borrowing Base Deficiency ON DEMAND to the Lender.

                    Without implying any limitation on the Lender's discretion
with respect to the Borrowing Base, the criteria for Eligible Receivables
contained in the definition of Eligible Receivables is in part based upon the
business operations of the Borrower existing on or about the Closing Date and
upon information and records furnished to the Lender by the Borrower. If at any
time or from time to time hereafter, the business operations of the Borrower
change or such information and records furnished to the Lender is materially
incorrect or misleading, the Lender in its discretion, may at any time and from
time to time during the duration of this Agreement change such criteria or add
new criteria. The Lender may communicate such changed or additional criteria to
the Borrower from time to time either orally or in writing.

                    2.1.4   Borrowing Base Report.

                    The Borrower will furnish to the Lender no less frequently
than monthly and at such other times as may be reasonably requested by the
Lender a report of the Borrowing Base (each a "Borrowing Base Report";
collectively, the "Borrowing Base Reports") in the form required from time to
time by the Lender, appropriately completed and duly signed. The Borrowing Base
Report shall contain the amount and payments on the Receivables, and the
calculations of the Borrowing Base, all in such detail, and accompanied by such
supporting and other information, as the Lender may from time to time request.
Upon the Lender's request upon the creation of any Receivables or at such other
intervals as the Lender may require, the Borrower will provide the Lender with:
(a) confirmatory assignment schedules; (b) copies of Account Debtor invoices;
(c) such further schedules, documents and/or information regarding any of the
Receivables as the Lender may reasonably require. The items to be provided
under this subsection shall be in form satisfactory to the Lender, certified as
true and correct by a Responsible Officer (or by any other officers or
employees of the Borrower whom a Responsible Officer from time to time
authorizes in writing to do so), and delivered to the Lender from time to time
solely for the Lender's convenience in maintaining records of the Collateral.
The failure of the Borrower to deliver any such items to the Lender shall not
affect, terminate, modify, or otherwise limit the Lender's security interests
in, and Liens on, the Collateral.

                    2.1.5  Revolving Credit Note.

                    The obligation of the Borrower to pay the Revolving Loan,
with interest, shall be evidenced by a promissory note (as from time to time
extended, amended, restated, supplemented or otherwise modified, the "Revolving
Credit Note") substantially in the form of EXHIBIT "A" attached hereto and made
a part hereof, with appropriate insertions. The Revolving Credit Note shall be
dated as of the Closing Date, shall be payable to the order of the Lender at
the times provided in the Revolving Credit Note, and shall be in the principal
amount of the Revolving Credit Committed Amount. The Borrower acknowledges and
agrees that, if the outstanding principal balance of the Revolving Loan
outstanding from time to time exceeds the face amount of the Revolving Credit
Note, the excess shall bear interest at the Post-Default Rate for the Revolving
Loan and shall be payable, with accrued interest, ON DEMAND. The Revolving
Credit Note shall not operate as a novation of any of the Obligations or
nullify, discharge, or release any such Obligations or the continuing
contractual relationship of the parties hereto in accordance with the
provisions of this Agreement.

                    2.1.6  Mandatory Prepayments of Revolving Loan.

"Revolving Loan Mandatory Prepayment" and collectively, the "Revolving Loan
Mandatory Prepayments") of the Revolving Loan at any time and from time to time
in such amounts requested by the Lender pursuant to Section 2.1.3 (Borrowing
Base) in order to cover any Borrowing Base Deficiency.

collectively the "Revolving Loan Optional Prepayments") the Revolving Loan, in
whole or in part without premium or penalty.

                    2.1.8  The Collateral Account.

                    The Borrower will deposit, or cause to be deposited, all
Items of Payment to a bank account designated by the Lender and from which the
Lender alone has power of access and withdrawal (the "Collateral Account").
Each deposit shall be made not later than the next Business Day after the date
of receipt of the Items of Payment. The Items of Payment shall be deposited in
precisely the form received, except for the endorsements of the Borrower where
necessary to permit the collection of any such Items of Payment, the Borrower
hereby agreeing to make such endorsement. In the event the Borrower shall fail
to do so, the Lender is hereby authorized by the Borrower to make the
endorsement in the name of the Borrower. Prior to such a deposit, the Borrower
will not commingle any Items of Payment with any of the other funds or property
of the Borrower, but will hold them separate and apart in trust and for the
account of the Lender.

                    In addition, if so directed by the Lender, the Borrower
shall direct the mailing of all Items of Payment from its Account Debtors to a
post-office box designated by the Lender, or to such other additional or
replacement post-office boxes pursuant to the request of


                                       19

<PAGE>   27


the Lender from time to time (collectively, the "Lockbox"). The Lender shall
have unrestricted and exclusive access to the Lockbox.

                    The Borrower hereby authorizes the Lender to inspect all
Items of Payment, endorse all Items of Payment in the name of the Borrower, and
deposit Items of Payment in the Collateral Account. The Lender reserves the
right, exercised in its sole and absolute discretion from time to time, to
provide to the Collateral Account credit prior to final collection of an Item
of Payment and to disallow credit for any Item of Payment which is
unsatisfactory to the Lender. In the event Items of Payment are returned to the
Lender for any reason whatsoever, the Lender may, in the exercise of its
discretion from time to time, forward such Items of Payment a second time. Any
returned Items of Payment shall be charged back to the Collateral Account, the
Revolving Loan Account, or other account, as appropriate.

                    The Lender will apply the whole or any part of the
collected funds credited to the Collateral Account against the Revolving Loan
(or with respect to Items of Payment which are not proceeds of accounts or
inventory or after a Default or Event of Default, against any of the
Obligations) or credit such collected funds to the depository account of the
Borrower with the Lender (or an Affiliate of the Lender), the order and method
of such application to be in the reasonable discretion of the Lender.

                    2.1.9  Revolving Loan Account.

                    The Lender will establish and maintain a loan account on
its books (the "Revolving Loan Account") to which the Lender will (a) debit (i)
the principal amount of each advance of the Revolving Loan made by the Lender
hereunder as of the date made, (ii) the amount of any interest accrued on the
Revolving Loan as and when due, and (iii) any other amounts due and payable by
the Borrower to the Lender from time to time under the provisions of this
Agreement in connection with the Revolving Loan, including, without limitation,
Enforcement Costs, Fees, late charges, and service, collection and audit fees,
as and when due and payable, and (b) credit all payments made by the Borrower
to the Lender on account of the Revolving Loan as of the date made including,
without limitation, funds credited to the Revolving Loan Account from the
Collateral Account. The Lender may debit the Revolving Loan Account for the
amount of any Item of Payment that is returned to the Lender unpaid. All credit
entries to the Revolving Loan Account are conditional and shall be readjusted
as of the date made if final and indefeasible payment is not received by the
Lender in cash or solvent credits. Any and all periodic or other statements or
reconciliations, and the information contained in those statements or
reconciliations, of the Revolving Loan Account shall be final, binding and
conclusive upon the Borrower in all respects, absent manifest error, unless the
Lender receives specific written objection thereto from the Borrower within
thirty (30) Business Days after such statement or reconciliation shall have
been received by the Borrower.

                    2.1.10  Revolving Credit Unused Line Fee.

quarter of one percent (1/4%) per annum of the average daily unused and
undisbursed portion of the Revolving Credit Committed Amount in

effect from time to time accruing during each calendar quarter. The accrued and
unpaid portion of the Revolving Credit Unused Line Fee shall be paid by the
Borrower to the Lender on the first day of each calendar quarter, commencing on
the first such date following the date hereof, and on the Revolving Credit
Termination Date.

        Section 2.2  The Letter of Credit Facility.

                     2.2.1  Letters of Credit.

                     Subject to and upon the provisions of this Agreement, and
as a part of the Revolving Credit Commitment, the Borrower may, upon the prior
approval of the Lender, obtain standby or commercial letters of credit (as the
same may from time to time be amended, supplemented or otherwise modified, each
a "Letter of Credit" and collectively the "Letters of Credit") from the Lender
from time to time from the Closing Date until the Business Day preceding the
Revolving Credit Termination Date. The Borrower will not be entitled to obtain
a Letter of Credit hereunder unless (a) after giving effect to the request, the
outstanding principal balance of the Revolving Loan and of the Letter of Credit
Obligations would not exceed the lesser of (i) the Revolving Credit Committed
Amount, or (ii) the most current Borrowing Base and (b) the sum of the
aggregate face amount of the then outstanding Letters of Credit (including the
face amount of the requested Letter of Credit) does not exceed Seven Hundred
Fifty Thousand Dollars ($750,000).

                     2.2.2  Letter of Credit Fees.

                     Prior to or simultaneously with the opening of each Letter
of Credit, the Borrower shall pay to the Lender, a letter of credit fee (each a
"Letter of Credit Fee" and collectively the "Letter of Credit Fees") in an
amount equal to two percent (2%) per annum of the amount of the Letter of
Credit. Such Letter of Credit Fees shall be paid upon the opening of the Letter
of Credit and upon each anniversary thereof, if any. In addition, the Borrower
shall pay to the Lender any and all additional issuance, negotiation,
processing, transfer or other fees to the extent and as and when required by
the provisions of any Letter of Credit Agreement; such additional fees are
included in and a part of the "Fees" payable by the Borrower under the
provisions of this Agreement.

                     2.2.3  Terms of Letters of Credit.

                     Each Letter of Credit shall (a) be opened pursuant to a
Letter of Credit Agreement, and (b) expire on a date not later than the
Business Day preceding the Revolving Credit Expiration Date; provided, however,
if any Letter of Credit does have an expiration date later than the Business
Day preceding the Revolving Credit Termination Date, as of the Business Day
preceding the Revolving Credit Termination Date an advance of the Revolving
Credit Facility shall be made by the Lender in the face amount of such Letter
of Credit (or Letters of Credit) and the proceeds thereof shall be deposited in
an account titled in the name of the Lender as trustee for the Borrower. The
proceeds of the trustee account referred to in the immediately preceding
sentence shall be held as collateral for the Letter of Credit (or Letters of
Credit) and in the event of a draw under the Letter of Credit (or Letters of
Credit), used to pay any such draw. The aggregate face amount of all Letters of
Credit at any one time outstanding and issued by the Lender pursuant to the
provisions of this Agreement, plus the amount of any unpaid Letter of



                                       21

<PAGE>   29


Credit Fees accrued or scheduled to accrue thereon, and less the aggregate
amount of all drafts issued under or purporting to have been issued under such
Letters of Credit that have been paid by the Lender, is herein called the
"Outstanding Letter of Credit Obligations".

                     2.2.4  Procedure for Letters of Credit.

                     The Borrower shall give the Lender written notice at least
three (3) Business Days prior to the date on which a Letter of Credit is
requested to be opened of their request for a Letter of Credit. Such notice
shall be accompanied by a duly executed and delivered Letter of Credit
Agreement. Upon receipt of the Letter of Credit Agreement and the Letter of
Credit Fee, the Lender shall process such Letter of Credit Agreement in
accordance with its customary procedures and open such Letter of Credit on the
Business Day specified in such notice.

                     2.2.5  Change in Law; Increased Cost.

                     If any change in any law or regulation or in the
interpretation thereof by any court or other Governmental Authority charged
with the administration thereof shall either (a) impose, modify or deem
applicable any reserve, special deposit or similar requirement against Letters
of Credit issued by the Lender, or (b) impose on the Lender any other condition
regarding this Agreement or any Letter of Credit, and the result of any event
referred to in clauses (a) or (b) above shall be to increase the cost to the
Lender of issuing, maintaining or extending the Letter of Credit or the cost to
the Lender of funding any obligation under or in connection with the Letter of
Credit, then, upon demand by the Lender, the Borrower shall immediately pay to
the Lender from time to time as specified by the Lender, additional amounts
which shall be sufficient to compensate the Lender for such increased cost,
together with interest on each such amount from the date demanded until payment
in full thereof at a rate per annum equal to the then highest current rate of
interest on the Revolving Loan. A certificate as to such increased cost
incurred by the Lender, submitted by the Lender to the Borrower, shall be
conclusive, absent manifest error.

        Section 2.3  General Financing Provisions.

                     2.3.1  Borrower's Representatives.

                     The Lender is hereby irrevocably authorized by the
Borrower to make advances under the Loan to the Borrower pursuant to the
provisions of this Agreement upon the written, oral or telephone request of any
one of the Persons who is from time to time a Responsible Officer of the
Borrower under the provisions of the most recent "Certificate" of corporate
resolutions of the Borrower on file with the Lender or who is an officer or
employee of the Borrower whom a Responsible Officer from time to time
authorizes in writing to do so. The Lender does not and shall not assume any
responsibility or liability for any errors, mistakes, and/or discrepancies in
the oral, telephonic, written or other transmissions of any instructions,
orders, requests and confirmations between the Lender and the Borrower in
connection with the Credit Facilities, any Loan or any other transaction in
connection with the provisions of this Agreement.

                     2.3.2  Use of Proceeds of the Loan.

                     The proceeds of each advance under the Loan shall be used
by the Borrower for Permitted Uses, and for no other purposes except as may
otherwise be agreed by the Lender in writing. The Borrower shall use the
proceeds of the Loan promptly.

                     2.3.3  Administrative and Audit Fees.

                     The Borrower shall pay to the Lender a quarterly
administrative and audit fee (each an "Administrative Fee" and collectively,
the "Administrative Fees") for administrative and/or audit services performed
in conjunction with the Revolving Credit Facility. The quarterly Administrative
Fee shall be $1,500 and shall be payable each quarter, in advance, on the first
(1st) day of each March, June, September and December until the Revolving
Credit Termination Date.

                     2.3.4  Computation of Interest and Fees.

                     All applicable Fees and interest shall be calculated on
the basis of a year of 360 days for the actual number of days elapsed. Any
change in the interest rate on any of the Obligations resulting from a change
in the Base Rate shall become effective as of the opening of business on the
day on which such change in the Base Rate is announced.

                     2.3.5  Payments.

                     All payments of the Obligations, including, without
limitation, principal, interest, Prepayments, and Fees, shall be paid by the
Borrower without setoff, recoupment or counterclaim to the Lender in
immediately available funds not later than 12:00 noon, Baltimore, Maryland time
on the due date of such payment. All such payments shall be made to the
Lender's principal office in Baltimore, Maryland or at such other location as
the Lender may at any time and from time to time notify the Borrower.
Alternatively, at its sole discretion, the Lender may charge any deposit
account of the Borrower at the Lender or any Affiliate of the Lender with all
or any part of any amount due to the Lender under this Agreement or any of the
other Financing Documents to the extent that the Borrower shall have not
otherwise tendered payment to the Lender. All payments shall be applied first
to any unpaid Fees, second to any and all accrued and unpaid late charges and
Enforcement Costs, third to any and all accrued and unpaid interest on the
Obligations, and then to the then unpaid principal balance of the Obligations,
all in such order and manner as shall be determined by the Lender in its sole
and absolute discretion.

                     2.3.6  Liens; Setoff.

                     The Borrower hereby grants to the Lender as additional
collateral and security for all of the Obligations, a continuing Lien on any
and all monies, Securities, and other personal property of the Borrower and any
and all proceeds thereof, now or hereafter held or received by, or in transit
to, the Lender or any Affiliate of the Lender from, or for the account of, the
Borrower, and also upon any and all depository accounts (whether general or
special) and credits of the Borrower, if any, with the Lender or any Affiliate
of the Lender, at any time existing, excluding any depository accounts held by
the Borrower in its capacity as trustee for

                                       23


<PAGE>   31


Persons who are not Affiliates of the Borrower. Without implying any limitation
on any other rights the Lender may have under the Financing Documents or
applicable Laws, during the continuance of an Event of Default, the Lender is
hereby authorized by the Borrower at any time and from time to time at the
Lender's option, without notice to, or consent of, the Borrower, to set off,
appropriate, seize, freeze and apply any or all items hereinabove referred to
against all Obligations then outstanding (whether or not then due), all in such
order and manner as shall be determined by the Lender in its sole and absolute
discretion.

                     2.3.7  Requirements of Law.

                     In the event that the Lender shall have determined in good
faith that (a) the adoption of any Laws regarding capital adequacy, or (b) any
change in such Laws or in the interpretation or application thereof or (c)
compliance by the Lender or any corporation controlling the Lender with any
request or directive regarding capital adequacy (whether or not having the
force of law) from any Governmental Authority or central bank, does or shall
have the effect of reducing the rate of return on the capital of the Lender or
such controlling corporation as a consequence of the Lender's obligations under
this Agreement to a level below that which the Lender or such corporation would
have achieved but for such adoption, change or compliance (taking into
consideration the policies of the Lender and its controlling corporation with
respect to capital adequacy) by an amount deemed by the Lender, in its
discretion, to be material, then from time to time, after submission by the
Lender to the Borrower of a written request therefor and a statement of the
basis for the Lender's determination, the Borrower shall pay to the Lender ON
DEMAND such additional amount or amounts in order to compensate the Lender or
its controlling corporation for any such reduction.

                     2.3.8  Funds Transfer Services.

                     (a) The Borrower has requested that the Lender and its
Affiliates make available to the Borrower electronic funds transfer services
and related security measures in connection with the Obligations. A copy of the
Lender's current Wire Transfer Procedures, including the Security Procedures,
is attached to this Agreement as EXHIBIT B. The Borrower acknowledges and
agrees that all electronic funds transfers made by the Lender or any Affiliate
of the Lender to, or for the account of, the Borrower shall be governed by, and
subject to, the Wire Transfer Procedures and the Security Procedures in effect
from time to time. The Borrower and the Lender agree that the current Wire
Transfer Procedures and the Security Procedures are commercially reasonable.
The Borrower further acknowledges and agrees, however, that the full scope of
the Security Procedures which the Lender and its Affiliates offer and strongly
recommend for electronic funds transfers is available only if the Borrower
communicates directly with the Lender or its Affiliate, as applicable, in
accordance with and as required by the Wire Transfer Procedures and the
Security Procedures. If the Borrower attempts to communicate with the Lender or
any Affiliate of the Lender by any other method or otherwise does not
communicate with the Lender and/or its Affiliate, as appropriate, in accordance
with the Wire Transfer Procedures and the Security Procedures, the Lender
and/or its Affiliate, as applicable, shall not be required to execute the
instructions of the Borrower, but if the Lender or such Affiliate, as
applicable, does so, the Borrower will be deemed to have refused and waived the
Security Procedures that the Lender or its Affiliate, as applicable, offers and
strongly recommends, and the Borrower will be bound by any funds transfer,
whether or not authorized,


                                       24

<PAGE>   32


which is issued in the Borrower's name and accepted by the Lender or any
Affiliate, as applicable, in good faith. The Lender or its Affiliate, as
applicable, may modify the Wire Transfer Procedures including, without
limitation, the Security Procedures at such time or times and in such manner as
the Lender and/or any Affiliate of the Lender, as applicable, in its or their
sole and absolute discretion, deems appropriate to meet then prevailing
standards of good banking practice. The Lender shall notify the Borrower of any
material change or modification to the Wire Transfer Procedures and/or the
Security Procedures. By continuing to use the wire transfer services of the
Lender and/or any Affiliate of the Lender following notice to the Borrower of
any such change or modification to the Wire Transfer Procedures and/or the
Security Procedures, the Borrower shall be deemed automatically to have agreed
to the Wire Transfer Procedures and the Security Procedures, as changed and/or
modified and to have further agreed that the Wire Transfer Procedures and the
Security Procedures, as changed and/or modified, are likewise commercially
reasonable. The Borrower further agrees to establish and maintain procedures to
safeguard the Security Procedures and any information related thereto. Neither
the Lender nor any Affiliate of the Lender is responsible for detecting any
error in any payment order sent by the Borrower to the Lender or any Affiliate
of the Lender.

                     (b) The Lender and its Affiliates, as applicable, will
generally use the Fedwire funds transfer system for domestic funds transfers,
and the funds transfer system operated by the Society for Worldwide
International Financial Telecommunication (SWIFT) for international funds
transfers. International funds transfers may also be initiated through the
Clearing House InterBank Payment System (CHIPs) or international cable.
However, the Lender and/or its Affiliates, as applicable, may use any means and
routes that the Lender or any such Affiliate, as applicable, in its sole
discretion, may consider suitable for the transmission of funds. Each payment
order, or cancellation thereof, carried out through a funds transfer system or
a clearinghouse will be governed by all applicable funds transfer system rules
and clearing house rules and clearing arrangements, whether or not the Lender
or any Affiliate, as applicable, is a member of the system, clearinghouse or
arrangement and the Borrower acknowledges that the right of the Lender or any
Affiliate, as applicable, to reverse, adjust, stop payment or delay posting of
an executed payment order is subject to the Laws, regulations, rules, circulars
and arrangements described herein.

                     (d) Changes in the Applicable Margin shall be made not
more frequently than quarterly based on the Borrower's Pricing Ratio,
determined by the Lender in the exercise of its sole and absolute discretion
from the reports required by Section 6.1.1 (Financial Statements), except that
the first such determination shall be made based on the Borrower's quarterly
financial statements for the period ending December 31, 1998 previously
delivered to the Lender and shall be effective as of the first day of the first
month after the Lender receives such statements. The Applicable Margin
(expressed as basis points) shall vary depending upon the Borrower's Pricing
Ratio, as follows:

                     2.4.2  Selection of Interest Rates.

                            (a) The Borrower may select the initial Applicable
Interest Rate or Applicable Interest Rates to be charged on the Loan.

                            (b) From time to time after the date of this
Agreement as provided in this Section, by a proper and timely Interest Rate
Election Notice furnished to the Lender in accordance with the provisions of

or Applicable Interest Rates for any Loans or may convert the Applicable
Interest Rate and, when applicable, the Interest Period, for any existing Loan
to any other Applicable Interest Rate or, when applicable, any other Interest
Period.

                            (c) The Borrower's selection of an Applicable
Interest Rate and/or an Interest Period, the Borrower's election to convert an
Applicable Interest Rate and/or an Interest Period to another Applicable
Interest Rate or Interest Period, and any other adjustments in an interest rate
are subject to the following limitations:


                                (i) the Borrower shall not at any time select
        or change to an Interest Period that extends beyond the Revolving
        Credit Expiration Date in the case of the Revolving Loan;

                                (ii) except as otherwise provided in Section
        2.4.4, no change from the Eurodollar Rate to the Base Rate shall become
        effective on a day other than a Business Day and on a day which is the
        last day of the then current Interest Period, no change of an Interest
        Period shall become effective on a day other than the last day of the
        then current Interest Period, and no change from the Base Rate to the
        Eurodollar Rate shall become effective on a day other than a day which
        is a Eurodollar Business Day;



                                       26

<PAGE>   34



                            (iii) any Applicable Interest Rate change for any
        Loan to be effective on a date on which any principal payment on
        account of such Loan is scheduled to be paid shall be made only after
        such payment shall have been made; 

                             (iv) no more than three (3) different Eurodollar
        Rates may be outstanding at any time and from time to time with respect

        be a Eurodollar Business Day; 

                             (vi) as of the effective date of a selection,
        there shall not exist a Default or an Event of Default; and 

                            (vii) the minimum principal amount of a Eurodollar
        Loan shall be One Hundred Thousand Dollars ($100,000).

                     (d) If a request for an advance under the Loan is not
accompanied by an Interest Rate Election Notice or does not otherwise include a
selection of an Applicable Interest Rate and, if applicable, an Interest
Period, or if, after having made a selection of an Applicable Interest Rate
and, if applicable, an Interest Period, the Borrower fails or is not otherwise
entitled under the provisions of this Agreement to continue such Applicable
Interest Rate or Interest Period, the Borrower shall be deemed to have selected
the Base Rate as the Applicable Interest Rate until such time as the Borrower
has selected a different Applicable Interest Rate and specified an Interest
Period in accordance with, and subject to, the provisions of this Section.

                     (e) The Lender will not be obligated to make Loans, to
convert the Applicable Interest Rate on Loans to another Applicable Interest
Rate, or to change Interest Periods, unless the Lender shall have received an
irrevocable written or telephonic notice (an "Interest Rate Election Notice")
from the Borrower specifying the following information:

                            (i) the amount to be borrowed or converted;

                           (ii) a selection of the Base Rate or the Eurodollar
Rate;

                          (iii) the length of the Interest Period if the
Applicable Interest Rate selected is the Eurodollar Rate; and

                     Any telephonic notice must be confirmed in writing within

the Lender not later than 10:00 a.m. (Baltimore City time) on the Business Day
of any requested borrowing or conversion in the case of a selection of the Base
Rate and not later than 10:00 a.m. (Baltimore City time) on the third Business
Day before the effective date of any requested borrowing or conversion in the
case of a selection of the Eurodollar Rate.

                     2.4.3  Inability to Determine Eurodollar Base Rate.

                     In the event that (a) the Lender shall have determined
that, by reason of circumstances affecting the London interbank eurodollar
market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Base Rate for any requested Interest Period with respect to a Loan
the Borrower has requested to be made as or to be converted to a Eurodollar
Loan or (b) the Lender shall determine that the Eurodollar Base Rate for any
requested Interest Period with respect to a Loan the Borrower has requested to
be made as or to be converted to a Eurodollar Loan does not adequately and
fairly reflect the cost to the Lender of funding or converting such Loan, the
Lender shall give telephonic or written notice of such determination to the
Borrower at least one (1) day prior to the proposed date for funding or
converting such Loan. If such notice is given, any request for a Eurodollar
Loan shall be made as or converted to a Base Rate Loan. Until such notice has
been withdrawn by the Lender, the Borrower will not request that any Loan be
made as or converted to a Eurodollar Loan.

                     2.4.4  Indemnity.

                     The Borrower agrees to indemnify and reimburse the Lender
and to hold the Lender harmless from any loss, cost (including administrative
costs) or expense which the Lender may sustain or incur as a consequence of (a)
a default by the Borrower in payment when due of the principal amount of or
interest on any Eurodollar Loan, (b) the failure of the Borrower to make, or
convert the Applicable Interest Rate of, a Loan after the Borrower has given a
Loan Notice or an Interest Rate Election Notice, (c) the failure of the
Borrower to make any prepayment of a Eurodollar Loan after the Borrower has
given notice of such intention to make such a prepayment, and/or (d) the making
by the Borrower of a prepayment of a Eurodollar Loan on a day which is not the
last day of the Interest Period for such Eurodollar Loan, calculated as
provided in the following paragraph. This agreement and covenant of the
Borrower shall survive termination or expiration of this Agreement and payment
of the other Obligations.

                     Contemporaneously with any prepayment of principal of a
Eurodollar Loan, a prepayment fee shall be due and payable to the Lender in an
amount equal to the product of

        (A)    the amount so prepaid

        multiplied by

        (B) the difference (but not less than zero) of

            (i) the constant maturity 360-day interest yield (as of the first
        day of the then effective Interest Period and expressed as a decimal)
        for a United States Treasury bill, note, or bond (a "Treasury
        obligation") selected by the Lender, in an aggregate amount comparable
        to the amount prepaid, and having, as of the first day of the then
        effective Interest Period, a remaining term approximately equal to the
        original Interest Period,

        minus



                                       28

<PAGE>   36



            (ii) the 360-day interest yield (as of the Business Day immediately
        preceding the prepayment date and expressed as a decimal) on such
        Treasury obligation and having, as of the Business Day immediately
        preceding the prepayment date, a remaining term until maturity
        approximately equal to the unexpired portion of the Interest Period

        multiplied by

        (C) the quotient of

            (i)  the number of calendar days in the unexpired portion of the
        Interest Period,

        divided by

            (ii) 360.

                 The applicable yields on the Treasury obligations described
above shall be determined based upon the Federal Reserve statistical release
H.15 published for the applicable determination dates set forth above. Any
Treasury obligation selected when the related Interest Period is one year or
less shall be United States Treasury Bills. The Lender shall not be obligated
or required to have actually reinvested the prepaid amount of the Eurodollar
Loan in any such Treasury obligation as a condition precedent to the Borrower's
being obligated to pay a prepayment fee as outlined above. The Lender shall not
be obligated to accept any prepayment of principal unless it is accompanied by
the prepayment fee, if any, due in connection therewith as calculated pursuant
to the provisions of this paragraph. No prepayment fee payable in connection
herewith shall in any event or under any circumstances be deemed or construed
as a penalty.

                 2.4.5  Payment of Interest.

                       (a) Unpaid and accrued interest on the Loans shall be
paid monthly, in arrears, on the first day of each calendar month, commencing
on the first such date after the date of this Agreement, and on the first day
of each calendar month thereafter, and at maturity (whether by acceleration,
declaration, extension or otherwise).

                       (b) Notwithstanding the foregoing, any and all unpaid
and accrued interest on any Base Rate Loan converted to a Eurodollar Loan or
prepaid shall be paid immediately upon such conversion and/or prepayment, as
appropriate.

                       (c) Unpaid and accrued interest on any Eurodollar Loan
shall be paid on the last Business Day of each Interest Period for such
Eurodollar Loan and at maturity (whether by acceleration, declaration,
extension or otherwise); provided, however that any and all unpaid and accrued
interest on any Eurodollar Loan prepaid prior to expiration of the then current
Interest Period for such Eurodollar Loan shall be paid immediately upon
prepayment.

                      None of the proceeds of the Loan will be used, directly
or indirectly, by the Borrower or any Subsidiary for the purpose of purchasing
or carrying, or for the purpose of reducing or retiring any indebtedness which
was originally incurred to purchase or carry, any "margin security" within the
meaning of Regulation G (12 CFR Part 207), or "margin stock" within the meaning
of Regulation U (12 CFR Part 221), of the Board of Governors of the Federal

contemplated in this Agreement a "purpose credit" within the meaning of said
Regulation G or Regulation U, or cause this Agreement to violate any other
regulation of the Board of Governors of the Federal Reserve System or the
Securities Exchange Act of 1934 or the Small Business Investment Act of 1958,
as amended, or any rules or regulations promulgated under any of such statutes.

                      4.1.9  Investment Company Act; Margin Securities.

business, properties, condition (financial or otherwise) or operations, present
or prospective, of the Borrower.

Borrower in connection with the Financing Documents (a) do not contain any
untrue statement of a material fact and (b) when taken in their entirety, do

returns, reports and forms for Taxes which, to the knowledge of the Borrower,

any assessment received by it, to the extent that such Taxes have become due,
unless and to the extent only that such Taxes, assessments and governmental
charges are currently contested in good faith and by appropriate proceedings by
the Borrower, such Taxes are not the subject of any Liens other than Permitted
Liens, and adequate reserves therefor have been established as required under
GAAP. All tax liabilities of the Borrower were as of the date of audited
financial statements referred to in Section 4.1.11 (Financial Condition), and
are now, adequately provided for on the books of the Borrower or its



                                       35

Subsidiaries, as appropriate. No tax liability has been asserted by the

which the Borrower or any commonly controlled entity has an obligation to
contribute is in "reorganization" within the meaning of ERISA Section 4241 nor
has notice been received by the Borrower or any commonly controlled entity that
such a Multi-employer Plan will be placed in "reorganization".

                       4.1.16  Title to Properties.

                       The Borrower has good and marketable title to all of its

best of the Borrower's knowledge, (a) no Hazardous Materials are located on any
real property owned, controlled or operated by of the Borrower or for which the
Borrower is, or is claimed to be, responsible, except for reasonable quantities
of necessary supplies for use by the Borrower in the ordinary course of its
current line of business and stored, used and disposed in accordance with
applicable Laws; and (b) no property owned, controlled or operated by the
Borrower or for which the Borrower has, or is claimed to have, responsibility

Borrower, (b) any and each other place of business of the Borrower, (c) the
location of all books and records pertaining to the Collateral, and (d) each

                       4.1.24  Compliance with Eligibility Standards.

                       Each Account included in the calculation of the
Borrowing Base does and will at all times meet and comply with all of the
standards for Eligible Receivables. With respect to those Accounts which the
Lender has deemed Eligible Receivables (a) there are no facts, events or
occurrences which in any way impair the validity, collectibility or
enforceability thereof or tend to reduce the amount payable thereunder; and (b)
there are no proceedings or actions known to the Borrower which are threatened
or pending against any Account Debtor which might result in any material
adverse change in the Borrowing Base.

                       4.1.25  Year 2000 Compliance.

                       The Borrower has (a) initiated a review and assessment
of all areas within its and each of its Subsidiaries' businesses and operations
(including those affected by suppliers, vendors and customers) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications used by the Borrower or any of its Subsidiaries (or suppliers,
vendors and customers) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999), (b) developed a plan and timeline for addressing the Year
2000 Problem on a timely basis, and (c) to date, implemented that plan in
accordance with that timetable. Based on the foregoing, the Borrower believes
that all computer applications (including those of its suppliers, vendors and
customers) that are material to its or any of its Subsidiaries' business and
operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1,
2000 (that is, be 'Year 2000 compliant"), except to the extent that a failure
to do so could not reasonably expected to have a material adverse effect.

Debtor may be lawfully entitled, and may accept, in connection therewith, the

of Receivables within such assignments. Receivables so assigned shall secure
payment of the Obligations and are not sold to the Lender whether or not any
assignment thereof, which is separate from this Agreement, is in form absolute.
The Borrower agrees that neither any assignment to the Lender nor any other
provision contained in this Agreement or any of the other Financing Documents
shall impose on the Lender any obligation or liability of the Borrower with
respect to that which is assigned and the Borrower hereby agrees to indemnify

(but in any event sufficient to avoid any co-insurance obligations) and with a
specific endorsement to each such insurance policy pursuant to which the
insurer agrees to give the Lender at least thirty (30) days written notice

or default of the Borrower shall affect the right of the Lender to recover

on a sale on approval basis. The Borrower hereby declares its intent that,

attached to any realty shall be deemed a fixture, which declaration shall be

under any of the other Financing Documents and the first priority of that Lien
subject only to the Permitted Liens. The Borrower will from time to time do
whatever the Lender may require by way of obtaining, executing, delivering,
and/or filing financing statements, landlords', mortgagees' or bailees'
waivers, notices of assignment and other notices and amendments and renewals
thereof and the Borrower will take any and all steps and observe such
formalities as the Lender may require, in order to create and maintain a valid
Lien upon, pledge of, or paramount security interest in, the Collateral,
subject to the Permitted Liens. The Borrower shall pay to the Lender on demand
all taxes, costs and expenses incurred by the Lender in connection with the

instrument. To the extent that the proceeds of any of the Accounts or
Receivables of the Borrower are expected to become subject to the control of,
or in the possession of, a party other than the Borrower or the Lender, the
Borrower shall cause all such parties to execute and deliver on the Closing
Date security documents, financing statements or other documents as requested
by the Lender and as may be necessary to evidence and/or perfect the security
interest of the Lender in those proceeds. The Borrower agrees that a copy of a
fully executed security agreement and/or financing statement shall be
sufficient to satisfy for all purposes the requirements of a financing
statement as set forth in Article 9 of the applicable Uniform Commercial Code.
The Borrower hereby irrevocably appoints the Lender as

documents and take any action which the Lender may require pursuant the
foregoing provisions of this Section 6.1.21.

Requirements.

                       In the event that the Borrower shall transfer its
principal place of business or the office where it keeps its records pertaining

Lender a subsequent opinion of counsel as to the filing, recording and other
requirements with which the Borrower has complied to maintain the Lien and
security interest in favor of the Lender in the Collateral.

                       6.1.24  Use of Premises and Equipment.

paid and this Agreement has been terminated, the Lender (a) after and during
the continuance of a Default or an Event of Default, may use any of the
Borrower's owned or leased lifts, hoists, trucks and other facilities or
equipment for handling or removing the Collateral; and (b) shall have, and is
hereby granted, a right of ingress and egress to the places where the
Collateral is located, and may proceed over and through any of the Borrower's
owned or leased property.

                       The Borrower agrees that the Lender may at any time
following an Event of Default take such steps as the Lender deems reasonably
necessary to protect the Lender's interest in, and to preserve the Collateral,
including, the hiring of such security guards or the placing of other security
protection measures as the Lender deems appropriate, may employ and maintain at
any of the Borrower's premises a custodian who shall have full authority to do
all acts necessary to protect the Lender's interests in the Collateral and may
lease warehouse facilities to which the Lender may move all or any part of the
Collateral to the extent commercially reasonable. The Borrower agrees to
cooperate fully with the Lender's efforts to preserve the Collateral and will
take such actions to preserve the Collateral as the Lender may reasonably
direct. All of the Lender's expenses of preserving the Collateral, including
any reasonable expenses relating to the compensation and bonding of a
custodian, shall be part of the Enforcement Costs.

<PAGE>   66

        Section 7.2  Remedies.

        Upon the occurrence of any Default or Event of Default, the Lender may
at any time thereafter exercise any one or more of the following rights, powers
or remedies:

                       7.2.1   Acceleration.

                       The Lender may declare the Obligations to be immediately
due and payable, notwithstanding anything contained in this Agreement or in any
of the other Financing Documents to the contrary, without presentment, demand,
protest, notice of protest or of dishonor, or other notice of any kind, all of
which the Borrower hereby waives.

                       7.2.2   Further Advances.

                       The Lender may from time to time without notice to the

credit under this Agreement and under any of the other Financing Documents.
Further, upon the occurrence of an Event of Default or Default specified in
Sections 7.1.5 (Receiver; Bankruptcy) or Section 7.1.6 (Involuntary Bankruptcy,
etc.), the Revolving Credit Commitment and any agreement in any of the
Financing Documents to provide additional credit shall immediately and
automatically terminate and the unpaid principal amount of the Notes (with
accrued interest thereon) and all other Obligations then outstanding, shall
immediately become due and payable without further action of any kind and
without presentment, demand, protest or notice of any kind, all of which are
hereby expressly waived by the Borrower.

                       7.2.3   Uniform Commercial Code.

                       The Lender shall have all of the rights and remedies of
a secured party under the applicable Uniform Commercial Code and other
applicable Laws. Upon demand by



                                       59

<PAGE>   67


the Lender, the Borrower shall assemble the Collateral and make it available to
the Lender, at a place designated by the Lender. The Lender or its agents may
without notice from time to time enter upon the Borrower's premises to take
possession of the Collateral, to remove it, to render it unusable, to process
it or otherwise prepare it for sale, or to sell or otherwise dispose of it.

                       Any written notice of the sale, disposition or other
intended action by the Lender with respect to the Collateral which is sent by
regular mail, postage prepaid, to the Borrower at the address set forth in
Section 8.1 (Notices), or such other address of the Borrower which may from
time to time be shown on the Lender's records, at least ten (10) days prior to
such sale, disposition or other action, shall constitute commercially
reasonable notice to the Borrower. The Lender may alternatively or additionally
give such notice in any other commercially reasonable manner. Nothing in this
Agreement shall require the Lender to give any notice not required by
applicable Laws.

                       If any consent, approval, or authorization of any state,
municipal or other governmental department, agency or authority or of any
person, or any person, corporation, partnership or other entity having any
interest therein, should be necessary to effectuate any sale or other
disposition of the Collateral, the Borrower agrees to execute all such
applications and other instruments, and to take all other action, as may be
required in connection with securing any such consent, approval or
authorization.

                      The Borrower recognizes that the Lender may be unable to
effect a public sale of all or a part of the Collateral consisting of
securities by reason of certain prohibitions contained in the Securities Act of
1933, as amended, and other applicable federal and state Laws. The Lender may,
therefore, in its discretion, take such steps as it may deem appropriate to
comply with such Laws and may, for example, at any sale of the Collateral
consisting of securities restrict the prospective bidders or purchasers as to
their number, nature of business and investment intention, including, without
limitation, a requirement that the Persons making such purchases represent and
agree to the satisfaction of the Lender that they are purchasing such
securities for their account, for investment, and not with a view to the
distribution or resale of any thereof. The Borrower covenants and agrees to do
or cause to be done promptly all such acts and things as the Lender may request
from time to time and as may be necessary to offer and/or sell the securities
or any part thereof in a manner which is valid and binding and in conformance
with all applicable Laws. Upon any such sale or disposition, the Lender shall
have the right to deliver, assign and transfer to the purchaser thereof the
Collateral consisting of securities so sold.


                       7.2.4   Specific Rights With Regard to Collateral.

                       In addition to all other rights and remedies provided
hereunder or as shall exist at law or in equity from time to time, the Lender
may (but shall be under no obligation to), without notice to the Borrower, and
the Borrower hereby irrevocably appoints the Lender as its attorney-in-fact,
with power of substitution, in the name of the Lender or in the name of the
Borrower or otherwise, for the use and benefit of the Lender, but at the cost
and expense of the Borrower and without notice to the Borrower:



                                       60

                       (a) request any account debtor obligated on any of the
Accounts to make payments thereon directly to the Lender, with the Lender
taking control of the cash and non-cash proceeds thereof;

                       (b) compromise, extend or renew any of the Collateral or
deal with the same as it may deem advisable;

                       (c) make exchanges, substitutions or surrenders of all
or any part of the Collateral;

                       (d) copy, transcribe, or remove from any place of

correspondence, invoices and documents, relating to or evidencing any of the

Borrower's or any Subsidiary's place(s) of business as may be reasonably
necessary to administer, control and collect the Collateral;

                       (e) demand, collect, receipt for and give renewals,
extensions, discharges and releases of any of the Collateral;

                       (f) institute and prosecute legal and equitable
proceedings to enforce collection of, or realize upon, any of the Collateral;

                       (g) settle, renew, extend, compromise, compound,
exchange or adjust claims in respect of any of the Collateral or any legal
proceedings brought in respect thereof;

                       (h) endorse or sign the name of the Borrower upon any
Items of Payment, certificates of title, Instruments, Securities, stock powers,
documents, documents of title, financing statements, assignments, notices, or
other writing relating to or part of the Collateral and on any Proof of Claim
in Bankruptcy against an Account Debtor;

                       (i) notify the Post Office authorities to change the
address for the delivery of mail to the Borrower to such address or Post Office
Box as the Lender may designate and receive and open all mail addressed to the
Borrower; and

                       (j) take any other action necessary or beneficial to
realize upon or dispose of the Collateral or to carry out the terms of this
Agreement.

                       7.2.5   Application of Proceeds.

                       Any proceeds of sale or other disposition of the
Collateral will be applied by the Lender to the payment of the Enforcement
Costs, and any balance of such proceeds will be applied by the Lender to the
payment of the balance of the Obligations in such order and manner of
application as the Lender may from time to time in its sole and absolute
discretion determine. If the sale or other disposition of the Collateral fails
to fully satisfy the Obligations, the Borrower shall remain liable to the
Lender for any deficiency.

                       Upon the occurrence and continuation of an Event of
Default, the Lender without notice to or demand upon the Borrower and without
waiving or releasing any of the Obligations or any Default or Event of Default,
may (but shall be under no obligation to) at any time thereafter make such
payment or perform such act for the account and at the expense of the Borrower,
and may enter upon the premises of the Borrower for that purpose and take all
such action thereon as the Lender may consider necessary or appropriate for
such purpose and the Borrower hereby irrevocably appoints the Lender as its
attorney-in-fact to do so, with power of substitution, in the name of the
Lender or in the name of the Borrower or otherwise, for the use and benefit of
the Lender, but at the cost and expense of the Borrower and without notice to
the Borrower. All sums so paid or advanced by the Lender together with interest
thereon from the date of payment, advance or incurring until paid in full at
the Post-Default Rate and all costs and expenses, shall be deemed part of the
Enforcement Costs, shall be paid by the Borrower to the Lender on demand, and

                       7.2.7   Other Remedies.

                       The Lender may from time to time proceed to protect or
enforce its rights by an action or actions at law or in equity or by any other
appropriate proceeding, whether for the specific performance of any of the
covenants contained in this Agreement or in any of the other Financing
Documents, or for an injunction against the violation of any of the terms of

other property of any nature whatsoever of the Borrower now or at any time
hereafter in the possession of, in transit to or from, under the control or
custody of, or on deposit with, the Lender.

extend to any subsequent or other Default or Event of Default, or impair any
right consequent thereto.

                       (c) No notice to or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in the
same, similar or other circumstance.

                       (d) No failure or delay by the Lender to insist upon the
strict performance of any term, condition, covenant or agreement of this
Agreement or of any of the other Financing Documents, or to exercise any right,
power or remedy consequent upon a breach thereof, shall constitute a waiver,
amendment or modification of any such term, condition, covenant or agreement or
of any such breach or preclude the Lender from exercising any such right, power
or remedy at any time or times.

                       (e) By accepting payment after the due date of any
amount payable under this Agreement or under any of the other Financing
Documents, the Lender shall not be deemed to waive the right either to require
prompt payment when due of all other amounts payable under this Agreement or
under any of the other Financing Documents, or to declare a default for failure
to effect such prompt payment of any such other amount.

        Section 8.3 Cumulative Remedies.

        The rights, powers and remedies provided in this Agreement and in the
other Financing Documents are cumulative, may be exercised concurrently or
separately, may be exercised from time to time and in such order as the Lender
shall determine and are in addition to, and not exclusive of, rights, powers
and remedies provided by existing or future applicable Laws. In order to
entitle the Lender to exercise any remedy reserved to it in this Agreement, it
shall not be necessary to give any notice, other than such notice as may be
expressly required in this Agreement. Without limiting the generality of the
foregoing, the Lender may:

                       (a) proceed against the Borrower with or without
proceeding against any Person (including, without limitation, any one or more
of the Personal Guarantors) who may be liable (by endorsement, guaranty,
indemnity or otherwise) for all or any part of the Obligations;

                       (b) proceed against the Borrower with or without
proceeding under any of the other Financing Documents or against any Collateral
or other collateral and security for all or any part of the Obligations;

                       (c) without reducing or impairing the obligation of the
Borrower and without notice, release or compromise with any guarantor or other
Person liable for all or any part of the Obligations under the Financing
Documents or otherwise;

                       (d) without reducing or impairing the obligations of the
Borrower and without notice thereof: (i) fail to perfect the Lien in any or all
Collateral or to release any or all the Collateral or to accept substitute
Collateral, (ii) approve the making of advances under the Revolving Loan under
this Agreement, (iii) waive any provision of this Agreement or the other
Financing Documents, (iv) exercise or fail to exercise rights of set-off or
other rights, or (v) accept partial payments or extend from time to time the
maturity of all or any part of the Obligations. 

        Section 8.4  Severability.

        In case one or more provisions, or part thereof, contained in this
Agreement or in the other Financing Documents shall be invalid, illegal or
unenforceable in any respect under any Law, then without need for any further
agreement, notice or action:

                       (a) the validity, legality and enforceability of the
remaining provisions shall remain effective and binding on the parties thereto
and shall not be affected or impaired thereby;

                       (b) the obligation to be fulfilled shall be reduced to
the limit of such validity;

                       (c) if such provision or part thereof pertains to
repayment of the Obligations, then, at the sole and absolute discretion of the
Lender, all of the Obligations of the Borrower to the Lender shall become
immediately due and payable; and


                                       64


<PAGE>   72


                       (d) if the affected provision or part thereof does not
pertain to repayment of the Obligations, but operates or would prospectively
operate to invalidate this Agreement in whole or in part, then such provision
or part thereof only shall be void, and the remainder of this Agreement shall
remain operative and in full force and effect.


        Section 8.5 Assignments by Lender.

        The Lender may, without notice to, or consent of, the Borrower, sell,
assign or transfer to or participate with any Person or Persons all or any part
of the Obligations, and each such Person or Persons shall have the right to
enforce the provisions of this Agreement and any of the other Financing
Documents as fully as the Lender, provided that the Lender shall continue to
have the unimpaired right to enforce the provisions of this Agreement and any
of the other Financing Documents as to so much of the Obligations that the
Lender has not sold, assigned or transferred. In connection with the foregoing,
the Lender shall have the right to disclose to any such actual or potential
purchaser, assignee, transferee or participant all financial records,
information, reports, financial statements and documents obtained in connection
with this Agreement and any of the other Financing Documents or otherwise.

        Section 8.6  Successors and Assigns.

        This Agreement and all other Financing Documents shall be binding upon
and inure to the benefit of the Borrower and the Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Lender.

        Section 8.7  Continuing Agreements.

        All covenants, agreements, representations and warranties made by the
Borrower in this Agreement, in any of the other Financing Documents, and in any
certificate delivered pursuant hereto or thereto shall survive the making by
the Lender of the Loan and the execution and delivery of the Notes, shall be
binding upon the Borrower regardless of how long before or after the date
hereof any of the Obligations were or are incurred, and shall continue in full
force and effect so long as any of the Obligations are outstanding and unpaid.
From time to time upon the Lender's request, and as a condition of the release
of any one or more of the Security Documents, the Borrower and other Persons
obligated with respect to the Obligations shall provide the Lender with such
acknowledgments and agreements as the Lender may require to the effect that
there exists no defenses, rights of setoff or recoupment, claims,
counterclaims, actions or causes of action of any kind or nature whatsoever
against the Lender, its agents and others, or to the extent there are, the same
are waived and released.

        Section 8.8  Enforcement Costs.

        The Borrower shall pay to the Lender on demand all Enforcement Costs,
together with interest thereon from the date incurred or advanced until paid in
full at a per annum rate of interest equal at all times to the Post-Default
Rate. Enforcement Costs shall be immediately due and payable at the time
advanced or incurred, whichever is earlier. Without implying any limitation on
the foregoing, the Borrower shall pay, as part of the Enforcement Costs, upon
demand any and all stamp and other Taxes and fees payable or determined to be
payable in connection with the execution and delivery of this Agreement and the
other Financing

Documents and to save the Lender harmless from and against any and all
liabilities with respect to or resulting from any delay in paying or omission
to pay any Taxes or fees referred to in this Section. The provisions of this
Section shall survive the execution and delivery of this Agreement, the
repayment of the other Obligations and shall survive the termination of this
Agreement.

        Section 8.9  Applicable Law; Jurisdiction.

                     8.9.1   Applicable Law.

                     As a material inducement to the Lender to enter into this
Agreement, the Borrower acknowledges and agrees that the Financing Documents,
including, this Agreement, shall be governed by the Laws of the State, as if
each of the Financing Documents and this Agreement had each been executed,
delivered, administered and performed solely within the State even though for
the convenience and at the request of the Borrower, one or more of the
Financing Documents may be executed elsewhere. The Lender acknowledges,
however, that remedies under certain of the Financing Documents that relate to
property outside the State may be subject to the laws of the state in which the
property is located.

                      8.9.2  Submission to Jurisdiction.

                      The Borrower irrevocably submits to the jurisdiction of
any state or federal court sitting in the State over any suit, action or
proceeding arising out of or relating to this Agreement or any of the other
Financing Documents. The Borrower irrevocably waives, to the fullest extent
permitted by law, any objection that it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding brought in any such court
and any claim that any such suit, action or proceeding brought in any such
court has been brought in an inconvenient forum. Final judgment in any such
suit, action or proceeding brought in any such court shall be conclusive and
binding upon the Borrower and may be enforced in any court in which the
Borrower is subject to jurisdiction, by a suit upon such judgment, provided
that service of process is effected upon the Borrower in one of the manners
specified in this Section or as otherwise permitted by applicable Laws.

                      8.9.3  Appointment of Agent for Service of Process.

                      The Borrower hereby irrevocably designates and appoints
Robert C. Bower at 8419 Terminal Road Newington, Virginia 22122, as the
Borrower's authorized agent to receive on the Borrower's behalf service of any
and all process that may be served in any suit, action or proceeding of the
nature referred to in this Section in any state or federal court sitting in the
State. If such agent shall cease so to act, the Borrower shall irrevocably
designate and appoint without delay another such agent in the State
satisfactory to the Lender and shall promptly deliver to the Lender evidence in
writing of such other agent's acceptance of such appointment and its agreement
that such appointment shall be irrevocable.

                      8.9.4  Service of Process.

                      The Borrower hereby consents to process being served in
any suit, action or proceeding of the nature referred to in this Section by (a)
the mailing of a copy thereof by



                                       66

<PAGE>   74


registered or certified mail, postage prepaid, return receipt requested, to
the Borrower at the Borrower's address designated in or pursuant to Section 8.1
(Notices), and (b) serving a copy thereof upon the agent, if any, designated
and appointed by the Borrower as the Borrower's agent for service of process by
or pursuant to this Section. The Borrower irrevocably agrees that such service
(y) shall be deemed in every respect effective service of process upon the
Borrower in any such suit, action or proceeding, and (z) shall, to the fullest
extent permitted by law, be taken and held to be valid personal service upon
the Borrower. Nothing in this Section shall affect the right of the Lender to
serve process in any manner otherwise permitted by law or limit the right of
the Lender otherwise to bring proceedings against the Borrower in the courts of
any jurisdiction or jurisdictions.

        Section 8.10  Duplicate Originals and Counterparts.

        This Agreement may be executed in any number of duplicate originals or
counterparts, each of such duplicate originals or counterparts shall be deemed
to be an original and all taken together shall constitute but one and the same
instrument.

        Section 8.11  Headings.

        The headings in this Agreement are included herein for convenience
only, shall not constitute a part of this Agreement for any other purpose, and
shall not be deemed to affect the meaning or construction of any of the
provisions hereof.

        Section 8.12   No Agency.

        Nothing herein contained shall be construed to constitute the Borrower
as the Lender's agent for any purpose whatsoever or to permit the Borrower to
pledge any of the Lender's credit. The Lender shall not be responsible nor
liable for any shortage, discrepancy, damage, loss or destruction of any part
of the Collateral wherever the same may be located and regardless of the cause
thereof. The Lender shall not, by anything herein or in any of the Financing
Documents or otherwise, assume any of the Borrower's obligations under any
contract or agreement assigned to the Lender, and the Lender shall not be
responsible in any way for the performance by the Borrower of any of the terms
and conditions thereof.

        Section 8.13   Date of Payment.

        Should the principal of or interest on any of the Notes become due and
payable on other than a Business Day, the maturity thereof shall be extended to
the next succeeding Business Day and in the case of principal, interest shall
be payable thereon at the rate per annum specified in the Notes during such
extension.

        Section 8.14   Entire Agreement.

        This Agreement is intended by the Lender and the Borrower to be a
complete, exclusive and final expression of the agreements contained herein.
Neither the Lender nor the Borrower shall hereafter have any rights under any
prior agreements pertaining to the matters addressed by this Agreement but
shall look solely to this Agreement for definition and determination of all of
their respective rights, liabilities and responsibilities under this Agreement.

        Section 8.15   Waiver of Trial by Jury.

        THE BORROWER AND THE LENDER HEREBY JOINTLY AND SEVERALLY WAIVE TRIAL BY
JURY IN ANY ACTION OR PROCEEDING TO WHICH THE BORROWER AND THE LENDER MAY BE
PARTIES, ARISING OUT OF OR IN ANY WAY PERTAINING TO (A) THIS AGREEMENT, (B) ANY
OF THE FINANCING DOCUMENTS, OR (C) THE COLLATERAL. THIS WAIVER CONSTITUTES A
WAIVER OF TRIAL BY JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR
PROCEEDINGS, INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO THIS
AGREEMENT.

        This waiver is knowingly, willingly and voluntarily made by the
Borrower and the Lender, and the Borrower and the Lender hereby represent that
no representations of fact or opinion have been made by any individual to
induce this waiver of trial by jury or to in any way modify or nullify its
effect. The Borrower and the Lender further represent that they have been
represented in the signing of this Agreement and in the making of this waiver
by independent legal counsel, selected of their own free will, and that they
have had the opportunity to discuss this waiver with counsel.

        Section 8.16   Liability of the Lender.

        The Borrower hereby agrees that the Lender shall not be chargeable for
any negligence, mistake, act or omission of any accountant, examiner, agency or
attorney employed by the Lender in making examinations, investigations or
collections, or otherwise in perfecting, maintaining, protecting or realizing
upon any lien or security interest or any other interest in the Collateral or
other security for the Obligations.

        By inspecting the Collateral or any other properties of the Borrower or
by accepting or approving anything required to be observed, performed or
fulfilled by the Borrower or to be given to the Lender pursuant to this
Agreement or any of the other Financing Documents, the Lender shall not be
deemed to have warranted or represented the condition, sufficiency, legality,
effectiveness or legal effect of the same, and such acceptance or approval
shall not constitute any warranty or representation with respect thereto by the
Lender.

        IN WITNESS WHEREOF, each of the parties hereto have executed and
delivered this Agreement under their respective seals as of the day and year
first written above.

$3,000,000                                                    McLean, Virginia
                                                             February 28, 1999

      FOR VALUE RECEIVED, SENSYS TECHNOLOGIES INC., a corporation organized
under the laws of the State of Delaware (the "Borrower"), promises to pay to
the order of NATIONSBANK, N. A., a national banking association (the "Lender"),
the principal sum of THREE MILLION DOLLARS ($3,000,000) (the "Principal Sum"),
or so much thereof as has been or may be advanced or readvanced to or for the
account of the Borrower pursuant to the terms and conditions of the Financing
Agreement (as hereinafter defined), together with interest thereon at the rate
or rates hereinafter provided, in accordance with the following:

      1.     Interest.

      Commencing as of the date hereof and continuing until repayment in full
of all sums due hereunder, the unpaid Principal Sum shall bear interest at the
Applicable Interest Rate or the Post Default Rate in effect from time to time
pursuant to the terms of the Financing Agreement. The Applicable Interest Rate
shall be determined in the manner provided in the Financing Agreement.

      2.     Payments and Maturity.

      The unpaid Principal Sum, together with interest thereon, shall be
payable as follows:

            (a) Interest only on the unpaid Principal Sum shall be due and
payable on the Interest Payment Date (as that term is defined in the Financing
Agreement); and

            (b) Unless sooner paid, the unpaid Principal Sum, together with
interest accrued and unpaid thereon, shall be due and payable in full on the
Revolving Credit Expiration Date (as that term is defined in the Financing
Agreement).

      The fact that the balance hereunder may be reduced to zero from time to
time pursuant to the Financing Agreement will not affect the continuing
validity of this Note or the Financing Agreement, and the balance may be
increased to the Principal Sum after any such reduction to zero.

      The Lender is authorized to deduct any payment due hereunder from the
Borrower's account #37500119089 issued by the Lender, on or after the date the
payment is due.

      3.     Default Interest.

      Upon the occurrence of an Event of Default (as hereinafter defined), the
unpaid Principal Sum shall bear interest thereafter at a rate four percent (4%)
per annum in excess of the Applicable Interest Rate until such Event of Default
is cured.

      4.     Late Charges.

      If the Borrower shall fail to make any payment under the terms of this
Note within fifteen (15) days after the date such payment is due, the Borrower
shall pay to the Lender on demand a late charge equal to five percent (5%) of
such payment.

      5.     Application and Place of Payments.

      All payments, made on account of this Note shall be applied first to the
payment of any late charge then due hereunder, second to the payment of accrued
and unpaid interest then due hereunder, and the remainder, if any, shall be
applied to the unpaid Principal Sum. All payments on account of this Note shall
be paid in lawful money of the United States of America in immediately
available funds during regular business hours of the Lender at its principal
office in Baltimore, Maryland or at such other times and places as the Lender
may at any time and from time to time designate in writing to the Borrower.

      6.     Prepayment.

            (c) Mandatory Prepayments. The Borrower shall make mandatory
prepayments of the Revolving Loan as required to comply with the provisions of
Section 2.1.6 of the Financing Agreement.

            (d) Voluntary Prepayments. Subject to the provisions of the
Financing Agreement, the Borrower may voluntarily prepay the Revolving Loan at
any time without premium or penalty.

      7.     Financing Agreement and Other Financing Documents.

      This Note is the "Revolving Credit Note" described in an Amended and
Restated Financing and Security Agreement of even date herewith by and between
the Borrower and the Lender (the "Financing Agreement"). The indebtedness
evidenced by this Note is included within the meaning of the term "Obligations"
as defined in the Financing Agreement. The term "Financing Documents" as used
in this Note shall mean collectively this Note, the Financing Agreement and any
other instrument, agreement, or document previously, simultaneously, or
hereafter executed and delivered by the Borrower and/or any other person,
singularly or jointly with any other person, evidencing, securing,

      9.     Events of Default.

      The occurrence of any one or more of the following events shall
constitute an event of default (individually, an "Event of Default" and
collectively, the "Events of Default") under the terms of this Note:

            (a) The failure of the Borrower to pay to the Lender when due any
and all amounts payable by the Borrower to the Lender under the terms of this
Note; or

            (b) The occurrence of an event of default (as defined therein)
under the terms and conditions of any of the other Financing Documents.

      10.    Remedies.

      Upon the occurrence of an Event of Default, at the option of the Lender,
all amounts payable by the Borrower to the Lender under the terms of this Note
shall immediately become due and payable by the Borrower to the Lender without
notice to the Borrower or any other person, and the Lender shall have all of
the rights, powers, and remedies available under the terms of this Note, any of
the other Financing Documents and all applicable laws. The Borrower and all
endorsers, guarantors, and other parties who may now or in the future be
primarily or secondarily liable for the payment of the indebtedness evidenced
by this Note hereby severally waive presentment, protest and demand, notice of
protest, notice of demand and of dishonor and non-payment of this Note and
expressly agree that this Note or any payment hereunder may be extended from
time to time without in any way affecting the liability of the Borrower,
guarantors and endorsers.

      11.    Confessed Judgment.

      The Borrower hereby appoints and designates Amy S. Owen, Esquire and
Brian F. Kenney, Esquire, respectively and individually, the Borrower's duly
constituted attorney-in-fact to confess judgment against the Borrower pursuant
to the provisions hereof and of Section 8.01-432 of the Code of Virginia of
1950, as amended, which judgment shall be confessed in the Clerk's Office of
the Circuit Court of Fairfax County, Virginia. The Borrower shall, upon the
Lender's request, name such additional or alternative persons designated by the
Lender as the Borrower's duly constituted attorney or attorneys-in-fact to
confess judgment against the Borrower in accordance with the terms hereof.
Furthermore, upon the Lender's request, the Borrower shall agree to the
designation of any additional circuit courts in the Commonwealth of Virginia in
which judgment may be confessed against the Borrower.

      Upon the occurrence of an Event of Default, the Borrower hereby
authorizes the above designated attorney-in-fact or any successor named
therefor to confess judgment against the Borrower for the amount of the unpaid
Principal Sum, all interest accrued and unpaid thereon, and all other amounts
payable by the Borrower to the Lender under the terms of this Note or any of
the other Financing Documents, together with court costs and attorneys' fees of
fifteen percent (15%) of the unpaid Principal Sum and interest then due
hereunder. The Borrower hereby releases, to the extent permitted by applicable
law, all errors and all rights of exemption, appeal, stay of execution,
inquisition, and other rights to which the Borrower may otherwise be entitled
under the laws of the United States of America or of any state or possession of
the United States of America now in force or which may hereafter be enacted.
The authority and power to appear for and enter judgment


                                       3


<PAGE>   4


against the Borrower shall not be exhausted by one or more exercises thereof or
by any imperfect exercise thereof and shall not be extinguished by any judgment
entered pursuant thereto. Such authority may be exercised on one or more
occasions or from time to time as often as the Lender shall deem necessary or
desirable, for all of which this Note shall be a sufficient warrant.

      12.    Expenses.

      The Borrower promises to pay to the Lender on demand by the Lender all
reasonable costs and expenses incurred by the Lender in connection with the
collection and enforcement of this Note, including, without limitation, all
reasonable attorneys' fees and expenses and all court costs.

      13.    Notices.

      Any notice, request, or demand to or upon the Borrower or the Lender
shall be deemed to have been properly given or made when delivered in
accordance with Section 8.1 of the Financing Agreement.

      14.    Miscellaneous.

      Each right, power, and remedy of the Lender as provided for in this Note
or any of the other Financing Documents, or now or hereafter existing under any
applicable law or otherwise shall be cumulative and concurrent and shall be in
addition to every other right, power, or remedy provided for in this Note or
any of the other Financing Documents or now or hereafter existing under any
applicable law, and the exercise or beginning of the exercise by the Lender of
any one or more of such rights, powers, or remedies shall not preclude the
simultaneous or later exercise by the Lender of any or all such other rights,
powers, or remedies. No failure or delay by the Lender to insist upon the
strict performance of any term, condition, covenant, or agreement of this Note
or any of the other Financing Documents, or to exercise any right, power, or
remedy consequent upon a breach thereof, shall constitute a waiver of any such
term, condition, covenant, or agreement or of any such breach, or preclude the
Lender from exercising any such right, power, or remedy at a later time or
times. By accepting payment after the due date of any amount payable under the
terms of this Note, the Lender shall not be deemed to waive the right either to
require prompt payment when due of all other amounts payable under the terms of
this Note or to declare an Event of Default for the failure to effect such
prompt payment of any such other amount. No course of dealing or conduct shall
be effective to amend, modify, waive, release, or change any provisions of this
Note.

      15.    Partial Invalidity.

      In the event any provision of this Note (or any part of any provision) is
held by a court of competent jurisdiction to be invalid, illegal, or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provision (or remaining part of the affected
provision) of this Note; but this Note shall be construed as if such invalid,
illegal, or unenforceable provision (or part thereof) had not been contained in
this Note, but only to the extent it is invalid, illegal, or unenforceable.

      16.    Captions.

      The captions herein set forth are for convenience only and shall not be
deemed to define, limit, or describe the scope or intent of this Note.

      17.    Governing Law.

      The provisions of this Note shall be construed, interpreted and enforced
in accordance with the laws of the Commonwealth of Virginia as the same may be
in effect from time to time.

      18.    Consent to Jurisdiction.

      The Borrower irrevocably submits to the jurisdiction of any state or
federal court sitting in the Commonwealth of Virginia over any suit, action, or
proceeding arising out of or relating to this Note. The Borrower irrevocably
waives, to the fullest extent permitted by law, any objection that the Borrower
may now or hereafter have to the laying of venue of any such suit, action, or
proceeding brought in any such court and any claim that any such suit, action,
or proceeding brought in any such court has been brought in an inconvenient
forum. Final judgment in any such suit, action, or proceeding brought in any
such court shall be conclusive and binding upon the Borrower and may be
enforced in any court in which the Borrower is subject to jurisdiction by a
suit upon such judgment provided that service of process is effected upon the
Borrower as provided in this Note or as otherwise permitted by applicable law.

      19.    Service of Process.

      The Borrower hereby irrevocably designates and appoints R.R. Bower, as
the Borrower's authorized agent to accept and acknowledge on the Borrower's
behalf service of any and all process that may be served in any suit, action,
or proceeding instituted in connection with this Note in any state or federal
court sitting in the Commonwealth of Virginia. If such agent shall cease so to
act, the Borrower shall irrevocably designate and appoint without delay another
such agent in the Commonwealth of Virginia satisfactory to the Lender and shall
promptly deliver to the Lender evidence in writing of such agent's acceptance
of such appointment and its agreement that such appointment shall be
irrevocable.

      The Borrower hereby consents to process being served in any suit, action,
or proceeding instituted in connection with this Note by (a) the mailing of a
copy thereof by certified mail, postage prepaid, return receipt requested, to
the Borrower and (b) serving a copy thereof upon the agent hereinabove
designated and appointed by the Borrower as the Borrower's agent for service of
process. The Borrower irrevocably agrees that such service shall be deemed to
be service of process upon the Borrower in any such suit, action, or
proceeding. Nothing in this Section shall affect the right of the Lender to
serve process in any manner otherwise permitted by law and nothing in this
Section will limit the right of the Lender otherwise to bring proceedings
against the Borrower in the courts of any jurisdiction or jurisdictions.

      20.    WAIVER OF TRIAL BY JURY.

      THE BORROWER HEREBY WAIVES TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO
WHICH THE BORROWER AND THE LENDER MAY BE PARTIES, ARISING OUT OF OR IN ANY WAY
PERTAINING TO (A) THIS NOTE OR


                                       5

(B) THE FINANCING DOCUMENTS. IT IS AGREED AND UNDERSTOOD THAT THIS WAIVER
CONSTITUTES A WAIVER OF TRIAL BY JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH
ACTIONS OR PROCEEDINGS, INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO
THIS NOTE.

      This waiver is knowingly, willingly and voluntarily made by the Borrower,
and the Borrower hereby represents that no representations of fact or opinion
have been made by any individual to induce this waiver of trial by jury or to
in any way modify or nullify its effect. The Borrower further represents that
it has been represented in the signing of this Note and in the making of this
waiver by independent legal counsel, selected of its own free will, and that it
has had the opportunity to discuss this waiver with counsel.

      21. Interest Rate Not to Exceed Applicable Laws.

      The interest rate required by this Note, the Financing Agreement or any
of the other Financing Documents shall not exceed the maximum rate permissible
under applicable laws, and any amounts paid in excess of such rate or rates
shall be applied to reduce the unpaid balance of the Principal Sum or shall be
refunded to the Borrower at the option of the Lender.

      22.    No Novation.

      This Note, is intended as a replacement of, and is in substitution for,
that certain Revolving Credit Note dated June 16, 1986 from the Borrower, as
maker, payable to the order of NationsBank, N. A. (as from time to time
extended, amended, restated, supplemented or otherwise modified, collectively,
the "Original Note"), but is not intended as a novation of the Original Note or
any of the Obligations evidenced by the Original Note. All references in the
Financing Agreement or any of the other Financing Documents to the Note shall
mean the Original Note, as amended and restated in accordance with the
provisions of this Note.

      IN WITNESS WHEREOF, the Borrower has caused this Note to be executed
under seal by its duly authorized officers as of the date first written above.
