             ASSIGNMENT OF CREDIT FACILITIES AND FINANCING DOCUMENTS

        THIS ASSIGNMENT OF CREDIT FACILITIES AND FINANCING DOCUMENTS (the
"Assignment") is made by and among BANK OF AMERICA, N.A., a national banking
association ("Assignor"), TECHTEAM RETAIL, LLC, a Michigan limited liability
company ("Assignee"), CYNTERGY CORPORATION, a Delaware corporation (the
"Borrower"), ROBERT N. GRIMES and his wife BETH GRIMES, each residents of the
State of Maryland (collectively, the "Guarantors" and individually, a
"Guarantor") and CYNTERGY EMEA, LTD (f/k/a Strategic Technology Services
International, Ltd.), a Delaware corporation (the "Pledgor").

                                 R E C I T A L S

        A.      Pursuant to that certain Financing and Security Agreement dated
January 29, 1999 (as amended, restated, renewed, supplemented or otherwise
modified from time to time, the "Financing Agreement"), by and between Assignor
and the Borrower, Assignor agreed to make available to the Borrower (i) a line
of credit for term loans in the maximum aggregate principal amount of One
Million Five Hundred Thousand Dollars ($1,500,000) (the "Equipment Line"), to be
used by the Borrower to finance and/or refinance the purchase of equipment, and
(ii) a revolving credit facility in the maximum principal amount of Six Million
Dollars ($6,000,000) (the "Revolving Loan"), to be used by the Borrower for
working capital. Assignor has also made available to the Borrower a term loan in
the original principal amount of One Hundred Sixty Nine Thousand Eight Hundred
Seventy Six and 00/100 Dollars ($169,876) (the "Additional Term Loan"). The
Equipment Line, the Revolving Loan, and the Additional Term Loan are hereinafter
called collectively the "Credit Facilities".

        B.      The Revolving Loan is evidenced by a Revolving Promissory Note
dated January 29, 1999 issued by the Borrower and made payable to the order of
Assignor (as amended, restated, renewed, supplemented or otherwise modified from
time to time, the "Revolving Note"). Advances under the Equipment Line are
evidenced by seven (7) separate term notes issued by the Borrower made payable
to the order of Assignor (as amended, restated, renewed, supplemented or
otherwise modified from time to time, the "Term Notes"). The Additional Term
Loan is evidenced by a Promissory Note dated February 5, 1999 issued by the
Borrower and made payable to the order of Assignor (as amended, restated,
renewed, supplemented or otherwise modified from time to time, the "Additional
Term Note"). The Revolving Note, the Term Notes and the Additional Term Note are
sometimes hereinafter called collectively the "Notes."

        C.      The Borrower's obligations in connection with the Credit
Facilities are secured by the Collateral (as defined in the Financing Agreement)
and are guaranteed by the Guarantors pursuant to and to the extent set forth in
(i) a Guaranty of Payment Agreement dated January 29, 1999 given by Robert N.
Grimes in favor of Assignor (as amended, restated, renewed, supplemented or
otherwise modified from time to time, the "Unlimited Guaranty"), and (ii) a
Limited Recourse Guaranty of Payment Agreement dated January 29, 1999 given by
Beth

<PAGE>

Grimes to Assignor (as amended, restated, renewed, supplemented or otherwise
modified from time to time, the "Limited Guaranty") (the Unlimited Guaranty and
the Limited Guaranty being hereinafter called collectively the "Guaranties").
The Financing Agreement, the Notes, the Guaranties, and all other documents now
or hereafter executed and delivered by the Borrower, the Guarantors, or any
other party or parties to evidence, secure, or guarantee, or otherwise in
connection with, the Credit Facilities are hereinafter called collectively the
"Financing Documents." As used herein, the term "Obligations" shall mean the
unpaid principal balance of the Credit Facilities, together with all accrued and
unpaid interest thereon and all of the other obligations owed by the Borrower
and/or the Guarantors to Assignor under and pursuant to the Financing Documents.

        D.      On or about March 1, 2000, Assignor notified the Borrower that
advances under the Revolving Loan exceeded availability under the Borrowing Base
by $2,677,882 (the amount of such excess being hereinafter called the
"Over-Advanced Amount") and that such circumstance constituted a default under
the Financing Agreement. Subsequent thereto, the Borrower requested that
Assignor waive such default as well as certain other defaults then existing on
the condition that the Borrower agree, among other things, to modify certain of
the terms of the Financing Documents, to cancel all remaining availability under
the Equipment Line, to increase the rate of interest payable on the
Over-Advanced Amount and to use its best efforts to raise additional equity
and/or obtain subordinated debt, mezzanine financing or other sums acceptable to
Assignor, the proceeds of which were to be used to repay the Borrower's
outstanding obligations. Accordingly, on or about June 29, 2000, the Borrower,
the Guarantors and Assignor entered into an Agreement (the "June 29th
Agreement") pursuant to which (a) the parties agreed to amend certain provisions
of the Financing Documents, and (b) Assignor agreed to forbear temporarily from
exercising its various rights and remedies under the Financing Documents,
subject to the terms and conditions set forth in the June 29th Agreement.

        E.      As provided in the June 29th Agreement, Assignor agreed to
extend the maturity date of the Revolving Loan until the earlier of June 30,
2000 (the "Revolving Loan Maturity Date") or the occurrence of a default under
either the June 29th Agreement or the Financing Documents. Assignor further
agreed that in the event the Borrower delivered to Assignor, on or prior to June
30, 2000, a commitment or expression of interest (acknowledged by third parties
where appropriate) of additional equity, subordinated debt, mezzanine financing
or other collateral or guarantees satisfactory to Assignor sufficient to repay,
guarantee or secure at least $1,500,000 of such Over-Advanced Amount, Assignor
would further extend the Revolving Loan Maturity Date until the earlier of
September 30, 2000 or the occurrence of a new default under the June 29th
Agreement or the other Financing Documents.

        F.      On December 31, 2000, the Revolving Note matured. As a result
thereof, as of said date, the Borrower owed Assignor in excess of $5,215,532
under the Revolving Note. Notwithstanding, the Borrower failed to pay to
Assignor the amounts then due.

        G.      By virtue of the Borrower's failure to comply with its
obligations under the Revolving Note, the Borrower defaulted on its obligations
under the other Notes and, as a result thereof, all sums due under said Notes
became immediately due and payable.

                                       2
<PAGE>

        H.      Subsequently thereto, the Borrower and the Guarantors again
requested that Assignor extend the maturity date of the Credit Facilities, waive
the existing defaults and refrain until at least March 31, 2001 from exercising
its other rights and remedies to give them time in which to either (i) find
alternative financing and/or (ii) sell the stock and/or assets of the Borrower
in order to satisfy their Obligations to Assignor. Assignor agreed to grant such
request, subject to and upon the terms and conditions set forth in that certain
Modification and Waiver Agreement dated as of February 9, 2001 (the "First
Modification").

        I.      Simultaneously with the execution of the First Modification, (i)
the Guarantors executed and delivered to Assignor a Stock Pledge Agreement
pursuant to which the Guarantors pledged to Assignor all of their stockholdings
in CynterCorp, Inc. (the "CynterCorp Stock Pledge"); (ii) the Pledgor and Robert
N. Grimes executed and delivered to Assignor a Stock Pledge Agreement pursuant
to which they pledged to Assignor all of their stockholdings in Cyntergy (EMEA)
Limited (the "Cyntergy UK Stock Pledge") and (iii) Cyntergy (EMEA) Limited
executed and delivered to Assignor a Stock Pledge Agreement pursuant to which
Cyntergy (EMEA) Limited pledged to Assignor its stockholdings in Cyntergy UK
Limited, a UK limited liability company (the "Cyntergy UK Stock Pledge") (the
CynterCorp Stock Pledge, the EMEA UK Stock Pledge, and the Cyntergy UK Stock
Pledge being hereinafter called collectively the "Stock Pledges").

        J.      On or about March 6, 2001, the Borrower entered into a letter of
intent with Technology Facility Management Plc of Oxfordshire, England ("TFM"),
pursuant to which TFM offered to purchase from the Pledgor and Robert N. Grimes
their stockholdings in Cyntergy (EMEA) Limited.

        K.      Subsequent thereto, following protracted negotiations with TFM,
said parties entered into a stock purchase agreement (the "Stock Purchase
Agreement"), pursuant to which the Pledgor and Robert N. Grimes sold to TFM
their stockholdings in Cyntergy (EMEA) Limited for $950,000, subject to certain
adjustments, if any, provided for therein. In consideration of Assignor's
consent to such sale and to release its security interest in the shares of
Cyntergy (EMA) Limited, Robert N. Grimes and Cyntergy EMA Ltd. assigned to
Assignor the net proceeds realized from such sale as well as their interest in
the two promissory notes issued and delivered by TFM in payment of the balance
of the purchase price thereof.

        L.      On or about August 26, 2001, Borrower, Guarantors, EMEA Delaware
and EMEA UK entered into a Forbearance Agreement with Assignor, which provides
for forbearance from action under the Loan Documents until the later of the full
repayment of the Obligations and September 30, 2001.

        M.      Recently, the Borrower informed Assignor that Assignee may be
interested in purchasing Assignor's interest in its various Credit Facilities
to, and Financing Documents with, the Borrower.

        N.      Following numerous discussions between Assignor and Assignee and
their respective counsel, Assignee has now offered to purchase from Assignor all
of its rights, title and interest in and to the Credit Facilities, the Notes and
other Financing Documents, and to assume all obligations thereunder, all upon
and subject to the terms and conditions hereinafter set forth.

counterclaims, actions or causes of action of any kind or nature whatsoever
against Assignor or any agent, affiliate, employee, director or officer of
Assignor, directly or indirectly, arising out of, based upon, or in any manner
connected with, any transaction, event, circumstance, action, failure to act, or
occurrence of any sort or type, whether known or unknown, which occurred,
existed, was taken, permitted or began prior to the Effective Date in accordance
with, pursuant to, or by virtue of, any of the terms or conditions of the
Financing Documents;

                (c)     they jointly and severally covenant and agree to
indemnify, protect, defend, and hold Assignor and Assignee, their respective
officers, directors, agents and employees, harmless from any claims, charges,
obligations and liabilities arising out of the Financing Agreement and other
Financing Documents and the obligations secured thereby arising from acts,
occurrences or omissions prior to the Effective Date; and

                (d)     they further covenant and agree to pay any fees,

based upon an enforceable order or contract, written or oral, for goods
delivered or for services performed, and the same were shipped, held, or
performed in accordance with such order or contract; (c) the title of the
Borrower to the Account and, except as to the account debtor and any creditor
which finances the account debtor's purchase of such goods, to any goods is
absolute and is not subject to any prior assignment, claim, lien, or security
interest, except Permitted Liens and Liens created by the account debtors in

the amount shown on the books of the Borrower and on any invoice, certificate,
schedule or statement delivered to the Lender is owing to the Borrower and no
partial payment has been received unless reflected with that delivery; (e) the
Account is not subject to any claim of reduction, counterclaim, setoff,
recoupment, or other defense in law or equity, or any claim for credits,
allowances, or adjustments by the account debtor because of returned, inferior,
or damaged goods or unsatisfactory services, or for any other reason, provided
that only the amount of the Account that is equal to the account debtor's claim
shall be excluded, and if the amount of such claim cannot be determined, then
only the amount that Lender reasonably estimates as the account debtor's claim
shall be excluded; (f) the account debtor has not returned or refused to retain,
or otherwise notified the Borrower of any dispute concerning, or claimed
nonconformity of, any of the goods or services from the sale of which the

<PAGE>

                        FINANCING AND SECURITY AGREEMENT

however, that this exclusion will not apply to any Account of an account debtor
which also has an Account with the Borrower which is current); (i) the Account

Account that is equal to the indebtedness owing to the account debtor shall be
excluded, and if the amount of such indebtedness cannot be determined, then only
the amount that Lender reasonably estimates as the indebtedness owing to the
account debtor claim shall be excluded (n) no bond has been issued or is
contemplated with respect to the goods or services furnished by the Borrower or
with respect to the project or contract for which those goods or services were
furnished; and (o) the Lender has not deemed the Account ineligible because of
uncertainty as to the creditworthiness of the account debtor or because the
Lender otherwise considers the collateral value thereof to the Lender to be
impaired or its ability to realize such value to be insecure. In the event of
any dispute, under the foregoing criteria, as to whether an Account is, or has
ceased to be, an Eligible Receivable, or whether a portion of an Account other
than the portion which may be subject to counterclaim or set-off shall be
classified as an Eligible Receivable, the reasonable decision of the Lender
shall control. In addition to the foregoing, any Account representing more than
twenty-five percent (25%) of the Borrower's total Accounts shall be subject to
review by the Lender. The Lender may require that receivables insurance be
obtained for such Account in order to include it as an Eligible Receivable. In
that connection, the Lender has reviewed the Account due from Cendant as
disclosed in the Borrower's accounts receivable aging report (the "Aging
Report") dated November 11, 1998. The Lender acknowledges that Cendant' s
obligations as an account debtor have been assigned to the Hospitality Trust
which has provided to the Borrower a pre-paid deposit of $3,000,000. In reliance
upon the accuracy of the foregoing representations~ the Cendant Account is
currently deemed an Eligible Receivable. In addition, although foreign Accounts
and Accounts of Subsidiaries or Affiliates are generally excluded from the
definition of Eligible Receivables, the Borrower may request and the Lender
shall determine whether to include any such Account in the definition of
Eligible Receivables under such terms and conditions as the Lender shall
provide. Whether or not included in the definition of Eligible Receivables,
foreign Accounts shall be subject to perfection of the Lender's lien pursuant to
the Laws of the applicable foreign nation at the Lender's discretion. The
Borrower has a g reed that the Account of Hilton International (United Kingdom)
disclosed on the Aging Report shall not be classified as an Eligible Receivable
as of the date hereof. Anything contained herein to the contrary
notwithstanding, Accounts which have been billed to the Account Debtor for
payment in advance of the performance of services for the Borrower's "Help Desk"
Services Program (the "Pre-Billed Receivables") will be considered Eligible
Receivables provided not more than $1,000,000 may be borrowed against the
Pre-Billed Receivables under the Borrowing Base.

        SECTION 2.1             The Line of Credit for Equipment Term Loans.

                        (a)     The Lender agrees to lend to the Borrower on a
revolving basis from time to time in the form of one or more term loans (the
"Term Loans" and each a "Term Loan") at the times and in such amounts as
required pursuant to the terms of this Agreement in the maximum aggregate
principal amount at any one time outstanding of One Million Five Hundred
Thousand Dollars ($1,500,000) (the "Equipment Line Committed Amount"). The
obligation of the Borrower to repay the advances under each Term Loan shall be
evidenced by one or more Term Notes (each a "Term Note" and collectively, the
"Term Notes") to be executed and delivered by the Borrower to the Lender at the
time of each advance (an "Equipment Advance" and collectively, the "Equipment
Advances") under the Term Loan, in the form attached hereto as EXHIBIT A-1.

                        (b)     The Borrower shall deliver to the Lender, at the
time of each Equipment Advance, an invoice for the Equipment to be purchased or
refinanced, provided, however, that the Borrower may not request Equipment
Advances for more than Two Hundred Thousand Dollars ($200,000) in the aggregate
at any time to refinance the purchase price of Equipment. Equipment Advances
made under the Term Loans may be for Equipment invoiced no earlier than January,
199_. In addition, at or prior to the time of each Equipment Advance, the
Borrower shall deliver evidence satisfactory to the Lender that the Equipment
being purchased is free and clear of all liens, other than those in favor of the
Lender, and will execute and deliver to the Lender such financing statements and
other items as the Lender may request in order to perfect its lien on such
Equipment.

                        (c)     Equipment Advances will be made under the Term
Loans until June 29,2000, when no further Equipment Advances will be permitted
under the Term Loans. Equipment Advances shall be used by the Borrower to
purchase or refinance Equipment and shall not exceed (i) seventy five percent
(750 o) of the Invoice Amount for Equipment other than rolling stock (100% for
the equipment loan from Franklin National Bank being refinanced with the initial
proceeds of the loan), or (ii) eighty percent (80%) of the Invoice Amount of any
Equipment, which is rolling stock. At no time shall the Lender make any
Equipment Advances if after giving effect to such request the aggregate amount
then outstanding under the Term Loans would exceed the Equipment Line Committed
Amount.

                        (d)     When the Borrower desires to obtain an Equipment
Advance, the Borrower shall notify the Lender (which notice shall be
irrevocable) by facsimile transmission to be received no later than 1:00 p.m.
Washington, D.C. time one (1) Business Day before the day on which the Equipment
Advance is to be made. Such notice shall be substantially in the form of EXHIBIT
B. The notice shall be signed by a Responsible Officer and include a copy of the
invoice for the Equipment to be financed.

                        (e)     Each Term Note shall bear interest and shall be
repaid by the Borrower over a period of up to five (5) years from the date of
the Equipment Advance, as selected by the Borrower at or prior to the

<PAGE>

time of each Equipment Advance and as more fully set forth in each Term Note.
The Borrower may prepay the principal sum outstanding on any Term Loan only in
accordance with the terms of each Term Note. Sums borrowed and repaid may not be
re-advanced under any Term Note, subject to the terms and conditions of this
Agreement.

                        (f)     The proceeds of the each Term Loan shall be used
by the Borrower for the purposes set forth in Recital A above, and, unless prior
written consent of the Lender is obtained, for no other purpose.

        SECTION 2.2             The Revolving Loan.

                        (a)     The Lender agrees to lend to the Borrower and
the Borrower agrees to borrow on a revolving basis from time to time the
principal amount (the "Revolving Loan") not to exceed at any time outstanding
the lesser (the "Revolving Loan Committed Amount") of Six Million Dollars
($6,000,000) or the Borrowing Base.

                        (b)     If at any time the outstanding principal balance
of the Revolving Loan exceeds the limitations provided in subsection (a) above,
the Borrower promises to pay to the order of the Lender, on demand, the amount
of the excess.

                        (c)     The obligation of the Borrower to repay the
advances under the Revolving Loan shall be evidenced by the Borrower's Revolving
Promissory Note of even date herewith (the "Revolving Promissory Note") payable
to the Lender in the form attached hereto as EXHIBIT A-2. The Revolving
Promissory Note shall bear interest and shall be repaid by the Borrower in the
manner and at the times set forth in the Revolving Promissory Note.

                        (d)     The Borrower may prepay the principal sum
outstanding on the Revolving Loan only in accordance with the terms of the
Revolving Note. Sums borrowed and repaid may be re-advanced under the terms and
conditions of this Agreement.

                        (e)     The proceeds of the Revolving Loan shall be used
by the Borrower for the purposes set forth in Recital A above, and, unless prior
written consent of the Lender is obtained, for no other purpose.

        SECTION 2.3             Revolving Loan Procedure.

                        (a)     Each advance under the Revolving Loan shall be
in an amount of not less than $50,000 or a multiple thereof. The Borrower shall
notify the Lender not later than 11:00 a.m. on the date of each proposed
advance.

                        (b)     The Borrower shall furnish to the Lender such
schedules, certificates; lists, records, reports, information and documents as
required by the Lender from time to time so that the Lender may, in its
discretion, determine the Borrowing Base.

                        (c)     In addition, the Borrower hereby irrevocably
authorizes the Lender to make advances under the Revolving Loan at any time and
from time to time, without further request from or notice to the Borrower, which
the Lender, in its sole and absolute discretion, deems necessary or appropriate
to protect the

<PAGE>

Lender's interests under this Agreement or otherwise, including, without
limitation, advances made to cover Overdrafts, principal of, and/or interest on,
any Loans, fees, and/or Enforcement Costs, prior to, on, or after the
termination of this Agreement, regardless of whether the aggregate amount of the
advances which the Lender may make hereunder exceeds the Revolving Credit
Committed Amount. The Lender shall have no obligation whatsoever to make any
advance under this subsection and the making of one or more advances under this
subsection shall not obligate the Lender to make other similar advance or
advances. Any such advances will be secured by the Collateral.

        SECTION 2.4             Revolving Loan Account.

        The Lender will establish and maintain a loan account on its books (the
"Revolving Loan Account") to which the Lender will debit (i) the principal
amount of each Revolving Loan made by the Lender hereunder as of the date made,
(ii) the amount of any interest accrued on the Revolving Loans as and when due,
and (ii) 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 Loans, 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 Loans as of the date made, the Lender reserving the right, exercised
in its sole and absolute discretion from time to time, to provide earlier credit
or to disallow credit for any Collection which is unsatisfactory to the Lender.

        The Lender may debit the Revolving Loan Account for the amount of any
Collection, which 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. The Borrower hereby promises to pay to the order of the Lender,
on demand, an amount equal to the excess, if any, of all debit entries over all
credit entries recorded in the Revolving Loan Account under the provisions of
this Agreement that do not represent principal or interest payments under the
Revolving Loan. All payments of principal and interest under the Revolving Loan
shall be payable pursuant to the terms of the Revolving Promissory Note.

        SECTION 2.5             Lockbox.

        The Lender will establish a lockbox managed by the Lender's Commercial
Credit Services Unit and from which the Lender alone has power of access and
withdrawal upon the occurrence of an Event of Default (the "Lockbox"), into
which the Borrower will deposit all Items of Payment on account. The Borrower
shall direct its customers and others as the Lender may require to forward
payments to the Lockbox. The Borrower shall deposit Items of Payment received
directly by the Borrower in the Lockbox not later than the next Banking Day
after the receipt thereof, and in precisely the form received, except for the
endorsements of the Borrower where necessary to permit the collection of any
such Items of Payment, which endorsement the Borrower hereby agrees to make.
Pending such deposit to the Lockbox, endorsement and/or other delivery thereof
to the Lender, the Borrower will not commingle any Items of Payment with any of
its other funds or property, but will hold them separate and apart therefrom in
trust and for the account of the Lender. Provided no Event of Default has
occurred and is continuing, the Lender will transfer to the Borrower's operating
account each Banking Day any funds from Items of Payment received in the
Lockbox.

        SECTION 2.6             Commitment Fee.

        The Borrower agrees to pay to the Lender on the first day of each Fee
Period commencing after the date of

<PAGE>

this Agreement a commitment fee (computed on the basis of a year consisting of
three hundred and sixty (360) days for the actual number of days elapsed) of one
quarter of one percent (.250%) per annum on the daily average of the unused
amount of the Revolving Loan.

        SECTION 2.7             Loan Fee.

        The Borrower has paid to the Lender a loan fee for the Revolving Loan in
the amount of Twenty One Thousand Dollars ($21,000), which fee is non refundable
and is earned when paid.

        SECTION 2.8     Transactions under this Agreement Between the Borrower
                        and the Lender.

        In respect to any advance and all other matters under or in connection
with this Agreement and any transactions contemplated hereby, the Borrower
authorizes the Lender to accept, rely upon, act upon and comply with, any verbal
or written instructions, requests, confirmations and orders of any employee or
representative of the Borrower designated by the Borrower in writing delivered
to the Lender from time to time. The Borrower acknowledges that the transmission
between the Borrower and the Lender of any such instructions, requests,
confirmations and orders involves the possibility of errors, omissions, mistakes
and discrepancies and agrees to adopt such internal measures and operational
procedures to protect its interests. By reason thereof, the Borrower hereby
assumes all risk of loss and responsibility for, releases and discharges the
Lender from any and all responsibility or liability for, and agrees to
indemnify, reimburse on demand and hold the Lender harmless from, any and all
claims, actions, damages, losses, liability and expenses by reason of, arising
out of or in any way connected with or related to, (i) the Lender's acceptance,
reliance and actions upon, compliance with or observation of any such
instructions, requests, confirmations or orders, and (ii) any such errors,
omissions, mistakes and discrepancies, except those caused by the Lender's gross
negligence or willful misconduct.

        SECTION 2.9             Account Statements.

        Any and all periodic or other statements or reconciliation's, and the
information contained in those statements or reconciliation's, of the Revolving
Loan Account shall be presumed conclusively to be correct and shall constitute
an account stated between the Lender and the Borrower unless the Lender receives
specific written objection thereto from the Borrower within sixty (60) Banking
Days after such statement or reconciliation shall have been sent by the Lender.

        SECTION 2.10            Overdraft Advances.

        If after the close of business on any Banking Day, any banking account
of the Borrower with the Lender is determined by the Lender to have an
Overdraft, the Lender, in its sole discretion on each and any such occasion may
(and is hereby irrevocably authorized by the Borrower to), but is not obligated
to, make an advance under the Revolving Loan to the Borrower in a principal
amount equal to any such Overdraft as of the close of business on such Banking
Day. All Overdrafts shall be secured by the Collateral.

                                   ARTICLE III

        As security for the payment of all of the Obligations, the Borrower
hereby assigns, grants and conveys to

<PAGE>

the Lender and agrees that the Lender shall have a perfected, continuing
security interest in all of the Collateral. The Borrower further agrees that the
Lender shall have in respect the Collateral all of the rights and remedies of a
secured party under the Maryland Uniform Commercial Code and under other
applicable Laws and Security Documents, as well as those provided in this
Agreement. The Borrower covenants and agrees to execute and deliver such
financing statements and other instruments and filings as are necessary in the
opinion of the Lender to perfect such security interest. Notwithstanding the
fact that the proceeds of the Collateral constitute a part of the Collateral,
the Borrower may not dispose of the Collateral, or any part thereof, other than
in the ordinary course of its business or as otherwise may be permitted by this
Agreement.

                                   ARTICLE IV

                            UNCONDITIONAL OBLIGATIONS

        The payment and performance by the Borrower of the Obligations shall be

deductions and without abatement, diminution or set-off, and until payment in
full of all of the Obligations, the Borrower: (a) will not suspend or
discontinue any payments provided for in the Notes; (b) will perform and observe
all of its other agreements contained in this Agreement, including (without

                To induce the Lender to make the Loans, the Borrower represents

a change or changes effecting such representations and warranties, shall be
deemed to represent and warrant to the Lender at the time each request for an
advance under the Loans is submitted and again at the time any advance is made
under the Loans that:

except where the failure to do so would not have a material adverse effect on
the operations or financial condition of the Borrower.

                        SECTION 5.7     Financial Condition.

        The financial statements of the Borrower dated ___________________,199_

been established as required under generally accepted accounting principles, and
except to the extent that Borrower has entered into a payment arrangement with
any Governmental Authority and Borrower is in compliance with such payment
arrangement.

<PAGE>

                        SECTION 5.9     Compliance With Law

        To the best of Borrower' knowledge, Borrower is in compliance in all
material respects with all laws, ordinances, governmental rules or regulations

new place of business or the closing of any of its existing places of business,
and of any change in the location of the places where the Collateral, or any
part thereof, or the books and records concerning the Collateral, or any part
thereof, are kept. The proper and only places to file financing statements with
respect to the Collateral within the meaning of the Uniform Commercial Code are

statement shall be sufficient to satisfy for all purposes the requirements of a
financing statement as set forth in Article 9 of the Maryland Uniform Commercial
Code.

including the Collateral, and the Collateral is free and clear of mortgages,
pledges, liens, charges and other encumbrances other than the Permitted Liens,
and other than liens with respect to debt that will be paid from the proceeds of
the Loan.

                        SECTION 5.12    Margin Stock.

        None of the proceeds of the Loans will be used, directly or indirectly,
by the Borrower for the purpose of purchasing or carrying, or for the purpose of
reducing or retiring any indebtedness which was originally incurred to purchase

207), or "margin stock" within the meaning of Regulation U (12 CFR Part 221), of
the Board of Governors of the Federal Reserve System (herein called "margin
security and "margin stock") or for any other purpose which might make the
transactions contemplated herein 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.

                        SECTION 5.13    ERISA.

which plan is now or previously has been maintained or contributed to by the

        (a) The Borrower has (i) begun analyzing the operations of the Borrower
and its Affiliates that could be adversely affected by failure to become Year

compliant in a timely manner, the implementation of which is on schedule in all
material respects. The Borrower reasonably believes that it will become Year

except to the extent that a failure to do so could not reasonably be expected to
have a material adverse effect upon the financial condition of the Borrower.

                (b)     The Borrower reasonably believes any suppliers and
vendors that are material to the operations of the Borrower or its subsidiaries

have a material adverse effect upon the financial condition of the Borrower.

                        SECTION 11.2    Consents and Approvals.

        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

securing any such consent, approval or authorization.

                        SECTION 11.3    Remedies, etc. Cumulative.

        Each right, power and remedy of the Lender as provided for in this
Agreement or in any of the other Financing Documents or now or hereafter
existing at law or in equity or by statute or otherwise shall be cumulative and
concurrent and shall be in addition to every other right, power or remedy
provided for in this Agreement or in any of the other Financing Documents or now
or hereafter existing at law or in equity, by statute or otherwise, 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. In order to
entitle the Lender to exercise any remedy reserved to it herein, it shall not be
necessary to give any notice, other than such notice as may be expressly
required in this Agreement.

<PAGE>

                        SECTION 11.4    No Waiver of Rights by the Lender.

        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 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 later time or times. 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 11.5    Entire Agreement.

        The Financing Documents shall completely and fully supersede all other
agreements, both written and oral, between the Lender and the Borrower relating
to the Obligations. Neither the Lender nor the Borrower shall hereafter have any
rights under such prior agreements but shall look solely to the Financing
Documents for definition and determination of all of their respective rights,
liabilities and responsibilities relating to the Obligations.

                        SECTION 11.6    Survival of Agreement: Successors and
                                        Assigns.

        All covenants, agreements, representations and warranties made by the
Borrower herein and in any certificate, in the Financing Documents and in any
other instruments or documents delivered pursuant hereto shall survive the
making by the Lender of the Loans and the execution and delivery of the Notes,
and shall continue in full force and effect so long as any of the Obligations
are outstanding and unpaid. Whenever in this Agreement any of the parties hereto
is referred to, such reference shall be deemed to include the successors and
assigns of such party; and all covenants, promises and agreements by or on
behalf of the Borrower, which are contained in this Agreement shall inure to the
benefit of the successors and assigns of the Lender, and all covenants, promises
and agreements by or on behalf of the Lender which are contained in this
Agreement shall inure to the benefit of the permitted successors and permitted
assigns of the Borrower, but this Agreement may not be assigned by the Borrower
without the prior written consent of the Lender.

                        SECTION 11.7    Expenses.

        The Borrower agrees to pay all out-of-pocket expenses of the Lender
(including the reasonable fees and expenses of its legal counsel) in connection
with the preparation of this Agreement, the recordation of all financing
statements and such other instruments as may be required by the Lender at the
time of; or subsequent to, the execution of this Agreement to secure the
Obligations (including any and all recordation tax and other costs and taxes
incident to recording), the enforcement of any provision of this Agreement and
the collection of the Obligations. The Lender agrees that the expense of closing
the Loan will not exceed $15,000 (for legal fees plus lien searches) plus $3,500
(for the Collateral Audit). The Borrower agrees to indemnify and save harmless
the Lender for any liability resulting from the failure to pay any required
recordation tax, transfer taxes, recording costs or any other expenses incurred
by the Lender in connection with the Obligations. The provisions of this Section
shall survive the execution and delivery of this Agreement and the repayment of
the Obligations. The Borrower further agrees to reimburse the Lender upon demand
for all out-of-pocket expenses (including reasonable attorneys' fees and legal
expenses) incurred by the Lender in enforcing any of the Obligations or any
security therefor, which

<PAGE>

agreement shall survive the termination of this Agreement and the repayment of
the Obligations.

                        SECTION 11.8    Counterparts.

        This Agreement may be executed in any number of counterparts all of
which together shall constitute a single instrument.

                        SECTION 11.9    Governing Law.

        This Agreement and all of the other Financing Documents shall be
governed by, and construed in accordance with the laws of the State of Maryland.

                        SECTION 11.10   Modifications.

        No modification or waiver of any provision of this Agreement or of any
of the other Financing Documents, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. 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.

                        SECTION 11.11   Illegality.

        If fulfillment of any provision hereof or any transaction related hereto
or to any of the other Financing Documents, at the time performance of such
provision shall be due, shall involve transcending the limit of validity
prescribed by law, then ipso facto, the obligation to be fulfilled shall be
reduced to the limit of such validity; and if any clause or provisions herein
contained other than the provisions hereof pertaining to repayment of the
Obligations operates or would prospectively operate to invalidate this Agreement
in whole or in part, then such clause or provision only shall be void, as though
not herein contained, and the remainder of this Agreement shall remain operative
and in full force and effect; and if such provision pertains to repayment of the
Obligations, then, at the option of the Lender, all of the Obligations of the
Borrower to the Lender shall become immediately due and payable.

                        SECTION 11.12   Extension of Maturity.

        Should the principal of or interest on the Notes become due and payable
on other than a Banking Day, the maturity thereof shall be extended to the next
succeeding Banking 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 11.13   Gender, etc.

        Whenever used herein, the singular number shall include the plural, the
plural the singular and the use of the masculine, feminine or neuter gender
shall include all genders.

                        SECTION 11.14   Headings.

        The headings in this Agreement are for convenience only and shall not
limit or otherwise affect any of the terms hereof.
