THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED IN THE ABSENCE OF
SUCH REGISTRATION OR AN EXEMPTION THEREFROM. THIS WARRANT AND SUCH SECURITIES
MAY NOT BE TRANSFERRED UNLESS IN COMPLIANCE WITH THE CONDITIONS SPECIFIED IN
THIS WARRANT.

                                                            January 27, 2002

                             EURONET WORLDWIDE, INC.
                                     WARRANT

         WHEREAS, pursuant to a certain Revolving Credit Agreement dated June
28, 2000 (the "Credit Agreement"), Euronet Worldwide, Inc. (formerly Euronet
Services Inc.) (the "Company") agreed to issue Michael J. Brown certain warrants
in consideration of Mr. Brown making loans to the Company, on terms provided in
the Credit Agreement. Such terms included an exercise price for each warrant of
90% of the 10 day average trading price of the Company's stock preceding on the
day on which each warrant was required to be issued to Mr. Brown.

         WHEREAS, the parties to the Credit Agreement subsequently agreed to
modify the terms under which such warrants were to be issued to provide that the
exercise price of warrants issued to Mr. Brown could not be lower than 100% of
the closing trading price of the Company's stock as of the date of the Credit
Agreement or any other Loan Document, as defined in the Credit Agreement, that
provides for issuance of warrants to Mr. Brown. The agreement to amend the
Credit Agreement was approved by the Board of Directors of the Company on
November 27, 2001 and included in an amendment to the Credit Agreement executed
on January 27, 2002.

         WHEREAS, the Company was required under the Credit Agreement to issue
Mr. Brown 15,000 warrants on June 28, 2000 and wishes now to issue such warrants
to Mr. Brown under such amended terms.

         NOW THEREFORE

         The Company, for value received, hereby certifies that Michael J. Brown
or his registered assigns, is entitled to purchase from the Company, at any time
or from time to time during the period specified in Section 2 hereof, 15,000
fully paid and nonassessable shares of Common Stock, par value US$0.02, of the
Company (the "Common Stock"), at an exercise price equal to US$8.25 ("US$" means
United States Dollars) per share, subject to adjustment hereunder (the "Exercise
Price"), and subject to the other terms herein. As used herein, the term
"Warrant Shares" means the shares of Common Stock issuable upon exercise of this
Warrant (the "Warrant").

         1. Manner of Exercise; Issuance of Certificates; Payment for Shares.
            -----------------------------------------------------------------
Subject to the provisions hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant, together with a
completed exercise agreement in the

<PAGE>

form attached hereto (the "Exercise Agreement"), to the Company during normal
business hours on any business day at the Company's principal executive offices
(or such other office or agency of the Company as it may designate by notice to
the holder hereof), and upon payment to the Company in cash, by certified or
official bank check or by wire transfer to an account specified by the Company
of the Exercise Price for the Warrant Shares specified in the Exercise
Agreement. The Warrant Shares so purchased shall be deemed to be issued to the
holder hereof or such holder's designee, as the record owner of such shares, as
of the close of business on the date on which this Warrant shall have been
surrendered, the completed Exercise Agreement shall have been delivered, and
payment shall have been made for such shares as set forth above. Certificates
for the Warrant Shares so purchased, representing the aggregate number of shares
specified in the Exercise Agreement, shall be delivered to the holder hereof
within five business days after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be requested by
the holder hereof and shall be registered in the name of such holder. In the
event this Warrant is exercised in part, the Company shall also deliver a new
Warrant to the holder hereof, which Warrant shall be identical to this Warrant,
except that the number of Warrant Shares exercisable therefor shall be decreased
by the number of Warrant Shares so purchased.

         2. Period of Exercise. This Warrant is exercisable at any time or from
            ------------------
time to time on or after the date first listed above, and before 5:00 p.m.,
United States Eastern Standard Time on the date following one year thereafter
(the "Exercise Period"), provided, however, that if the Company is in default as
provided in the last sentence of Section 7.1.2 of the Revolving Credit Agreement
dated June 28, 2000 pursuant to which this Warrant is issued (the "Credit
Agreement"), then the Exercise Period shall expire three business days after the
date on which all Obligations, as defined in the Credit Agreement, have been
paid.

         3. Certain Agreements of the Company. The Company covenants as follows:
            ---------------------------------

            (a) Shares to be Fully Paid. All Warrant Shares shall, upon issuance
                -----------------------
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, and charges with respect to the
issue thereof.

            (b) Reservation of Shares. During the Exercise Period, the Company
                ---------------------
shall at all times have authorized, and reserved for the purpose of issuance
upon exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

            (c) Certain Actions Prohibited. The Company shall not, by amendment
                --------------------------
of its certificate of incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed by it hereunder, but shall at all
times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may reasonably be requested by
the holder of this Warrant in order to protect the exercise privilege of the
holder of this Warrant against impairment, consistent with the tenor and purpose
of this Warrant. Without limiting the generality of the foregoing, the Company
shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

                                       2

<PAGE>

            (d) Successors and Assigns. This Warrant shall be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

         4. Antidilution Provisions. During the Exercise Period, the Exercise
            -----------------------
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Section 4.

            (a) Subdivision or Combination of Common Stock. If the Company at
                ------------------------------------------
any time subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the Common Stock into a greater
number of shares, then, after the record date for effecting such subdivision,
the Exercise Price in effect immediately prior to such subdivision shall be
proportionately reduced and the number of Warrant Shares shall be
proportionately increased. If the Company at any time combines (by reverse stock
split, recapitalization, reorganization, reclassification or otherwise) the
Common Stock into a smaller number of shares, then, after the record date for
effecting such combination, the Exercise Price in effect immediately prior to
such combination shall be proportionately increased and the number of Warrant
Shares shall be proportionately decreased.

            (b) Rights; Options; Warrants. In case the Company shall issue
                -------------------------
rights, options, warrants or convertible or exchangeable securities (other than
a convertible or exchangeable security subject to Section 4(a)) to all holders
of its Common Stock, entitling them to subscribe for or purchase shares of
Common Stock at a price per share which is lower (at the record date for such
issuance) than the then Current Market Value (defined in Section 4(c) below) per
share of Common Stock, the number of Warrant Shares issuable upon exercise of
each Warrant thereafter shall be determined by multiplying the number of Warrant
Shares theretofore purchasable upon exercise of each Warrant by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of such rights, options, warrants or
convertible or exchangeable securities plus the number of additional shares of
Common Stock offered for subscription or purchase, and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
the issuance of such rights, options, warrants or convertible or exchangeable
securities plus the number of shares which the aggregate offering price of the
total number of shares of Common Stock so offered would purchase at the then
Current Market Value per share of Common Stock. Such adjustment shall be made
whenever such rights, options, warrants or convertible or exchangeable
securities are issued, and shall become effective retroactively immediately
after the record date for the determination of shareholders entitled to receive
such rights, options, warrants or convertible or exchangeable securities.

            (c) Issuance of Common Stock at Lower Values. In case the Company
                ----------------------------------------
shall, in a transaction in which Sections 4(a) and 4(b) are inapplicable, issue
or sell shares of Common Stock, or rights, options, warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase shares
of Common Stock to an Affiliate (defined below) of the Company, at a price per
share of Common Stock (determined in the case of such rights, options, warrants
or convertible or exchangeable securities, by dividing (A) the total amount
receivable by the Company in consideration of the issuance and sale of such
rights, options, warrants or convertible or exchangeable securities, plus the
total consideration, if any, payable to the Company upon exercise, conversion or
exchange thereof, by (B) the total number of shares of Common Stock covered by
such rights, options, warrants

                                       3

<PAGE>

or convertible or exchangeable securities) that is lower than the Current Market
Value per share of Common Stock in effect immediately prior to such sale or
issuance, then the the number of Warrant Shares issuable upon exercise of each
Warrant thereafter shall be determined by multiplying the number of Warrant
Shares theretofore purchasable upon exercise of such Warrant by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately after such sale or issuance and the denominator of which shall be
the number of shares of Common Stock outstanding immediately prior to such sale
or issuance plus the number of shares of Common Stock which the aggregate
consideration received (determined as provided below) for such sale or issuance
would purchase at such Current Market Value per share of Common Stock. Such
adjustment shall be made successively whenever any such sale or issuance is
made. For purposes of this Section 4(c), the shares of Common Stock which the
holder of any such rights, options, warrants or convertible or exchangeable
securities shall be entitled to subscribe for or purchase shall be deemed to be
issued and outstanding as of the date of such sale and issuance and the
consideration received by the Company therefor shall be deemed to be the
consideration received by the Company for such rights, options, warrants or
convertible or exchangeable securities, plus the consideration or premiums
stated in such rights, options, warrants or convertible or exchangeable
securities to be paid for the shares of Common Stock covered thereby.

         In case the Company shall issue and sell shares of Common Stock or
rights, options, warrants or convertible or exchangeable securities containing
the right to subscribe for or purchase shares of Common Stock for a
consideration consisting, in whole or in part, of property other than cash or
its equivalent, then in determining the "price per share of Common Stock" and
the "consideration" receivable by or payable to the Company for purposes of the
first sentence of this Section 4(c), the Board of Directors of the Company shall
determine, in good faith, the fair value of such property, which determination
shall be evidenced by a resolution of the Board of Directors of the Company. In
case the Company shall issue and sell rights, options, warrants or convertible
or exchangeable securities containing the right to subscribe for or purchase
shares of Common Stock, together with one or more other securities as part of a
unit at a price per unit, then in determining the "price per share of Common
Stock" and the "consideration" receivable by or payable to the Company for
purposes of the first sentence of this Section 4(c), the Board of Directors of
the Company shall determine, in good faith, the fair value of the rights,
options, warrants or convertible or exchangeable securities then being sold as
part of such unit, which determination shall be evidenced by a resolution of the
Board of Directors of the Company.

         For purposes of Section 4(b) and this Section 4(c), "Current Market
Value" per share of Common Stock or any other security at any date means (i) if
the security is not registered under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), (a) the value of the security, determined in good
faith by the Board of Directors of the Company and certified in a resolution of
the Board of Directors of the Company, based on the most recently completed
arm's-length transaction between the Company and a person or entity other than
an Affiliate of the Company and the closing of which occurs on such date or
shall have occurred within the six-month period preceding such date, or (b) if
no such transaction shall have occurred on such date or within such six-month
period, the fair market value of the security as determined by a nationally or
regionally recognized independent financial expert (provided that, in the case
of the calculation of Current Market Value for determining the cash value of
fractional shares, any such determination within six months that is, in the good
faith judgment of the Board of Directors of the Company, a reasonable
determination of value, may

                                       4

<PAGE>

be utilized) or (ii) (a) if the security is registered under the Exchange Act,
the average of the daily closing sales prices of the securities for the 20
consecutive trading days immediately preceding such date, or (b) if the
securities have been registered under the Exchange Act for less than 20
consecutive trading days before such date, then the average of the daily closing
sales prices for all of the trading days before such date for which closing
sales prices are available, in the case of each of (ii)(a) and (ii)(b), as
certified by the Chief Executive Officer, President, any Vice President or the
Chief Financial Officer of the Company. The closing sales price for each such
trading day shall be: (A) in the case of a security listed or admitted to
trading on any United States national securities exchange or quotation system,
the closing sales price, regular way, on such day, or if no sale takes place on
such day, the average of the closing bid and asked prices on such day, (B) in
the case of a security not then listed or admitted to trading on any national
securities exchange or quotation system, the last reported sale price on such
day, or if no sale takes place on such day, the average of the closing bid and
asked prices on such day, as reported by a reputable quotation source designated
by the Company, (C) in the case of a security not then listed or admitted to
trading on any national securities exchange or quotation system and as to which
no such reported sale price or bid and asked prices are available, the average
of the reported high bid and low asked prices on such day, as reported by a
reputable quotation service, or a newspaper of general circulation in the
Borough of Manhattan, City and State of New York, customarily published on each
business day, designated by the Company, or, if there shall be no bid and asked
prices on such day, the average of the high bid and low asked prices, as so
reported, on the most recent day (not more than 30 days prior to the date in
question) for which prices have been so reported and (D) if there are not bid
and asked prices reported during the 30 days prior to the date in question, the
Current Market Value shall be determined as if the securities were not
registered under the Exchange Act. "Affiliate" means, with respect to any
specified person or entity, (a) any person or entity directly or indirectly
controlling or controlled by or under direct or indirect common control with
such specified person or entity or (b) any person or entity that owns, directly
or indirectly, 10% or more of such specified person's or entity's voting capital
stock or any director of such specified person or entity.

            (d) Consolidation, Merger or Sale. In case the Company after the
                -----------------------------
date hereof (a) shall consolidate with or merge into any other entity and shall
not be the continuing or surviving corporation of such consolidation or merger,
(b) shall permit any other entity to consolidate with or merge into the Company
and the Company shall be the continuing or surviving entity but, in connection
with such consolidation or merger, all outstanding shares of Common Stock shall
be changed into or exchanged for stock or other securities of any other entity
or cash or any other property, (c) shall transfer all or substantially all of
its properties or assets to any other person or entity, or (d) shall effect a
capital reorganization or reclassification of the Common Stock (other than a
capital reorganization or reclassification for which adjustment in the Exercise
Price is provided in Section 4(a)), then, and in the case of each such
transaction, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the holder of this Warrant,
upon the exercise hereof at any time after the consummation of such transaction,
shall be entitled to receive (at the aggregate Exercise Price in effect at the
time of such consummation for all Common Stock issuable upon such exercise
immediately prior to such consummation), in lieu of the Common Stock issuable
upon such exercise immediately prior to such consummation, the highest amount of
securities, cash or other property to which such holder would have been entitled
as a shareholder upon such consummation if such holder had exercised this
Warrant immediately prior thereto, subject to adjustments (subsequent to such
consummation) as nearly equivalent as possible to the adjustments provided for
in this Section 4. The Company

                                       5

<PAGE>

shall not effect any such consolidation, merger, or sale of assets, or capital
reorganization or reclassification unless prior to the consummation thereof, the
continuing or surviving corporation (if other than the Company) assumes by
written instrument the obligations under this Section 4 and the obligations to
deliver to the holder of this Warrant such securities, cash or other property
as, in accordance with the foregoing provisions, the holder may be entitled to
acquire.

            (e) Distribution of Assets. In case the Company shall declare or
                ----------------------
make any distribution of its assets to all holders of Common Stock as a partial
liquidating dividend, by way of return of capital or otherwise, other than a
dividend payable in shares of Common Stock or in cash out of earnings of the
Company, the holder of this Warrant shall be entitled upon exercise of this
Warrant to receive the amount of cash, securities or other property that would
have been payable to the holder had such holder been the holder of such shares
of Common Stock on the record date for the determination of stockholders
entitled to such distribution.

            (f) Notice of Adjustment. Upon the occurrence of any event that
                --------------------
requires any adjustment of the Exercise Price, the Company shall give notice
thereof to the holder of this Warrant, which notice shall state the Exercise
Price resulting from such adjustment and the increase or decrease, if any, in
the number of Warrant Shares, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

            (g) Adjustment of Exercise Price. No adjustment of the Exercise
                ----------------------------
Price shall be made in an amount less than 1% of the Exercise Price in effect at
the time such adjustment is otherwise required to be made, but any such lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to not less than 1% of such Exercise Price. In the
event that any adjustment of the Exercise Price as required herein results in a
fraction of a cent, such Exercise Price shall be rounded up to the nearest cent.

            (h) No Fractional Shares. If any exercise of this Warrant would
                --------------------
result in the issuance of a fractional share of Common Stock, such fractional
share shall be disregarded and the number of shares of Common Stock issuable
upon such exercise shall be the nearest whole number of shares.

            (i) Other Notices. In case at any time:
                -------------

               (i)  the Company shall declare any dividend upon the Common Stock
                    payable in shares of stock of any class or make any other
                    distribution (other than dividends or distributions payable
                    in cash out of retained earnings) to the holders of the
                    Common Stock;

               (ii) the Company shall offer for subscription pro rata to all
                    holders of the Common Stock any additional shares of stock
                    of any class or other rights;

              (iii) there shall be any capital reorganization of the Company,
                    or reclassification of the Common Stock or sale of all or
                    substantially all its assets to another entity;

                                       6

<PAGE>

              (iv) there shall be a voluntary or involuntary dissolution,
                   liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the holder of this Warrant
notice of (a) the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution or subscription rights, or for determining the
holders of Common Stock entitled to vote in respect of any such transaction, and
(b) the date (or, if not then known, a reasonable approximation thereof by the
Company) when such transaction shall occur. Such notice shall also specify the
date on which the holders of Common Stock shall be entitled to receive such
dividend, distribution or subscription rights or to exchange their Common Stock
or stock or other securities or property deliverable upon consummation of such
transaction. Such notice shall be given at least 30 days prior to the record
date or the date on which the Company's books are closed in respect thereto.
Failure to give any such notice or any defect therein shall not affect the
validity of any action referred to in clauses (i), (ii), (iii) and (iv) above.

            (j) Certain Events. In case any event shall occur as to which
                --------------
paragraphs (a), (b), (c), (d) or (e) of this Section 4 are not strictly
applicable but the failure to make any adjustment would not fairly protect the
rights represented by this Warrant in accordance with the essential intent of
such provisions, the Company shall give notice of such event as provided in
Section 4(f) and shall make an appropriate adjustment in the Exercise Price and
the number of Warrant Shares to preserve, without dilution, the rights
represented by this Warrant.

         5. Issue Tax. The issuance of certificates for Warrant Shares upon the
            ---------
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof;
provided that the holder shall pay all transfer taxes owed upon the issuance of
such shares in the name of any person or entity designed by the holder.

         6. No Rights as a Stockholder. Prior to the exercise of this Warrant,
            --------------------------
the holder hereof, as such, shall not be entitled to any rights of a stockholder
of the Company, including, without limitation, the right to vote, to consent, to
exercise any preemptive right, to receive any notice of meetings of stockholders
for the election of directors of the Company or any other matter or to receive
any notice of any proceedings of the Company, except as may be specifically
provided for herein.

         7. Transfer, Exchange, and Replacement of Warrant; Resale of Warrant
            -----------------------------------------------------------------
Shares.

               (a)  Restriction on Transfer. THIS WARRANT (INCLUDING ANY
                    -----------------------
                    REPLACEMENT WARRANT) MAY NOT BE SOLD, TRANSFERRED, ASSIGNED
                    OR OTHERWISE DISPOSED OF (WHETHER BY OUTRIGHT OR COLLATERAL
                    ASSIGNMENT) EXCEPT FOR THE EXERCISE OF THIS WARRANT IN
                    ACCORDANCE WITH ITS TERMS. THE HOLDER OF THIS WARRANT SHALL
                    BE BOUND BY THE TRANSFER RESTRICTIONS CONTAINED HEREIN.

                    ----------------------
                    satisfactory to the Company of the loss, theft, destruction,
                    or mutilation of this Warrant and, in the case of any such
                    loss, theft, or destruction, upon delivery of an indemnity
                    agreement reasonably satisfactory in form and amount to the
                    Company, or, in the case of any such mutilation, upon
                    surrender and cancellation of this Warrant, the Company, at
                    its expense, shall execute and deliver, in lieu thereof, a
                    new Warrant of like tenor.

               (c)  Cancellation; Payment of Expenses. Upon the surrender of
                    ---------------------------------
                    this Warrant in connection with any replacement as provided
                    in this Section 7, this Warrant shall be promptly cancelled
                    by the Company. The Company shall pay all taxes and all
                    other expenses (other than legal expenses, if any, incurred
                    by the holder) and charges payable in connection with the
                    preparation, execution, and delivery of Warrants pursuant to
                    this Section 7.

               (d)  Register. The Company shall maintain, at its principal
                    --------
                    executive offices (or such other office or agency of the
                    Company as it may designate by notice to the holder hereof),
                    a register for this Warrant, in which the Company shall
                    record the name and address of the person in whose name this
                    Warrant has been issued.

               (e)  Restriction on Resale. The Warrant Shares have not been
                    ---------------------
                    registered under the Securities Act or any state securities
                    laws, and may not be sold or transferred unless (i)
                    subsequently registered thereunder or (ii) the undersigned

                                    (7)      Lender shall promptly notify the

         Lender for any drawing under a Letter of Credit shall be absolute and

         defense to payment the Borrower may claim or have against the Lender,
         the beneficiary of the Letter of Credit or any other Person;

                                    (8)      Unless the Borrower makes
         reimbursement from another source on the day of the drawing under any
         Letter of Credit, the Borrower shall be deemed to have requested an
         Advance under the Revolving Loan in the amount of the drawing, and
         (i) Lender, at its option, may make such an Advance and apply the
         proceeds of the Advance to satisfy the Borrower's obligation to
         reimburse Lender for the amount drawn on the Letter of Credit; and
         (ii) the Advance shall be repayable, with interest, in accordance
         with the terms and conditions of the Revolving Note; and

         and remains uncured, and no event has occurred or circumstance exists
         which, with the passage of time or the giving of notice or both,
         would constitute an Event of Default.

                                    ------------------------------

                                    --------------------

Agreement. These fees are in addition to interest payable under the Revolving
Note:

                                    (1)      an annual commitment fee of 15
         basis points (.15%), payable in equal quarterly installments over the
         term of the Revolving Loan based on the Maximum Revolving Commitment

         Revolving Commitment Amount and payable quarterly, in arrears,
         commencing on the first day following the end of the first fiscal
         quarter of Borrower after the date of this Agreement. The unused fee
         shall be determined by applying a per-diem rate of interest based on
         the interest rate set forth herein, calculated on the basis of a 360
         day year, to the actual number of days that the portion of the
         Maximum Revolving Commitment Amount is unused.

                                    (3)      a fee for any draw on a letter of
         credit honored by Lender in an amount of 1.5% of the draw amount.

                                    (4)      The Lender reserves the right to
          perform field examinations at any time, in its sole discretion. Each

Amended and Restated Loan Agreement Draft #4                                 11

<PAGE>

obligation of Borrower to Lender whether now or hereafter existing, of every
kind and description, whether or not evidenced by notes or other instruments,
and whether or not such liability or obligations are direct or indirect, fixed
or contingent, liquidated or unliquidated, the Borrower hereby assigns, grants
and conveys to the Lender a security interest in the Collateral. In addition,
except as prohibited by law, Borrower grants to Lender a security interest in
all accounts of Borrower with Lender or any of Lender's Affiliates. The
Borrower further agrees that the Lender shall have in respect of the Collateral
all of the rights and remedies of a secured party under the Uniform Commercial
Code, other applicable law and this Agreement. The Borrower covenants and
agrees to execute and deliver such financing statements and other instruments
and filings or perform any and all acts as are necessary in the opinion of the
Lender to perfect, maintain and protect the security interest hereby granted.
The Borrower shall 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.

         4.2      Certain Rights of the Lender. The Lender shall have the right,
                  ----------------------------
but not the obligation, (i) to pay any taxes or levies on the Collateral or any
costs to repair or to preserve the Collateral; and (ii) to cure any defaults by
Borrower on contracts by the Borrower intended to give rise to Accounts. Such
payments and the costs of curing such defaults shall constitute Advances under
the Revolving Note and shall be secured pursuant to this Agreement
notwithstanding that such Advances may cause the unpaid principal balance of
the Loan to exceed the Maximum Revolving Commitment Amount.

         4.3      Financing Statements. At the request of the Lender, Borrower
                  --------------------
will join with the Lender in executing financing statements, continuation
statements and other documents with respect to the Collateral pursuant to the
Uniform Commercial Code or otherwise, in form satisfactory to the Lender, and
Borrower will pay the cost of filing the same in all public offices wherever
the Lender deems filing to be necessary or desirable. Borrower agrees that a
carbon, photographic, photostatic or other reproduction of this Agreement or of
a financing statement is sufficient as a financing statement; provided,
however, that it shall not limit the obligations of Borrower as previously set
forth herein. Borrower grants the Lender the right, at the Lender's option, to
file any or all such financing statements, continuation statements and other
documents pursuant to the Uniform Commercial Code and otherwise, without
Borrower's signature, and irrevocably appoints the Lender as Borrower's
attorney-in-fact to execute any such statements and documents in Borrower's
name and to perform all other acts which the Lender deems appropriate to
perfect and to continue the security interests conferred by this Agreement.

         4.4      Records of Collateral; Information. Borrower at all times will
                  ----------------------------------
maintain accurate books and records covering the Collateral. Borrower
immediately will mark all books and records with an entry showing the absolute
assignment of and granting of a security interest in all Collateral to Lender,
and hereby grants the Lender the right to audit the books and records of
Borrower relating to Collateral at any time and from time to time. Borrower
shall (i) promptly furnish the Lender with any information with respect to
Collateral requested by Lender; (ii) allow the Lender or its representatives to
inspect the Collateral, at any time and wherever located, and to inspect and
copy, or furnish the Lender or its representatives with copies of all records
relating to the Collateral; (iii) furnish the Lender or its representatives such
information as the Lender may request to identify the Collateral, at the time
and in the form requested by

<PAGE>

Lender; and (iv) deliver upon request to Lender shipping and delivery receipts
evidencing the shipment of goods and invoices evidencing the receipt of the
Collateral and payment for the Collateral.

         4.5      No Release. No injury to the Collateral, loss or destruction
                  ----------
of the Collateral, failure to perfect or to continue the perfection of Lender's
security interest in the Collateral, or release of Lender's security interest
in the Collateral, or any part of it, shall relieve Borrower of any obligation
under this Agreement or under any of the other Loan Documents. Borrower
expressly waives all defenses based on suretyship or impairment of collateral,
and shall not be released or discharged of any obligation under the Loan
Documents, in whole or in part, by Lender's failure to protect or preserve the
Collateral. No Person, in deciding to enter into this Loan Agreement, has
relied on the execution of this Loan Agreement or the granting of a security
interest in Collateral by any other Person. Each Person comprised by the term
Borrower waives notice of any change in financial condition of any Person
liable for the Loans or any part thereof, and agrees that maturity of the Loans
or any part thereof may be accelerated, extended or renewed one or more times
by Lender in its discretion, without notice to the Person and without affecting
Lender's security interest in the Collateral. Lender shall not be required to
bring any action against any other Person or to resort to any other security or
to any balance of any deposit account as a condition of enforcing its rights
against any of the Collateral.

         4.8      Indemnification. In any suit, proceeding or action brought by
                  ---------------
or against the Lender relating to the Collateral, the Borrower will save,
indemnify and keep the Lender harmless from and against all reasonable expense,
loss or damage suffered by reason of any defense, set-off, counterclaim,
recoupment or reduction of liability whatsoever of any obligor thereunder,
arising out of a breach by the Borrower of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to or
in favor of such obligor or its successors from the Borrower, and all such
obligations of the Borrower shall be and remain enforceable against and only
against the Borrower and shall not be enforceable against the Lender. The
foregoing obligation of the Borrower to indemnify the Lender shall survive the
payment of the Loans and the termination of this Agreement but shall not extend
to any suit, proceeding or action arising out of the Lender's gross negligence
or willful misconduct.

         ARTICLE 5.  BORROWER'S REPRESENTATIONS AND WARRANTIES.

time or both) under any law, regulation, order or any other requirement of any
court, tribunal, arbitrator or governmental authority, any terms of the Articles
or Certificate of Incorporation or Bylaws of Borrower, or any contract,
agreement or other arrangement binding upon or affecting Borrower or any of its
properties, or (ii) result in the creation, imposition or acceleration of any
indebtedness or any Encumbrance of any nature upon, or with respect to, Borrower
or any of its properties, except such Encumbrances in favor of Lender.

         5.4      Litigation. Except as previously disclosed to the Lender in
                  ----------
writing, there is no claim, litigation, proceeding or investigation pending,
threatened or reasonably anticipated against or affecting Borrower, its
properties or business, this Agreement, any of the other Loan Documents, or any
of the transactions contemplated hereby or thereby, before or by any court,
tribunal, arbitrator or governmental authority, and there is no possibility of
any judgment, liability or award which reasonably may be expected to result in
any material adverse change in the business, operations, prospects, properties
or assets or condition, financial or otherwise, of Borrower. Borrower is not in
default with respect to any judgment, order, writ, injunction, decree, rule,
award or regulation of any court, governmental instrumentality or agency,
commission, board, bureau, arbitrator or arbitration panel.

marketable title to all of its properties and assets (whether real or personal),
and there exist no Encumbrances on any of Borrower's properties or assets,
including without limitation, the Collateral. All personal property of Borrower
which is necessary for Borrower's operations is in good operating condition and
repair, and is suitable and adequate for the uses for which it is being used.
Upon the execution and delivery of this Agreement, and upon the filing of
financing statements or the Lender's taking possession of the Collateral, as the
case may be, the Lender will have a good, valid and perfected first priority
lien and security interest in the Collateral, subject to no Encumbrance in favor

                  ---------
or condition (financial or otherwise) of Borrower or Guarantor, or any other
event, has occurred since the date of the most recent financial statements
submitted to the Lender by Borrower, which change might adversely affect the
ability of Borrower to perform or comply with all terms, conditions and
agreements to be performed or complied with by Borrower under this Agreement or
under any of the other Loan Documents, or to perform the transactions
contemplated by this Agreement or the other Loan Documents.

                  -----
required by any governmental authority to be filed by Borrower, and such returns
and reports are true and correct. Borrower has paid all taxes, assessments and
other government charges imposed upon it or its income, profits or properties,
or upon any part thereof, other than those presently payable without penalty or
interest and Borrower has timely filed all claims for refunds to which Borrower
is entitled. The amounts reserved as a liability for income and other taxes
payable in the most recent financial statements of Borrower provided to the
Lender are sufficient for the payment of all unpaid federal, state, county and
local income, excise, property and other taxes, whether or not disputed, of
Borrower accrued for or applicable to the period and on the dates of such
financial statements and all years and periods prior thereto, and for which
Borrower may be liable in its own right or as a transferee of the assets of, or
as successor to, any other Person.

         5.9      No Event of Default. As of the date this representation and
                  -------------------
warranty is made (or remade), no Event of Default, and no event which with
notice, lapse of time or other condition would constitute an Event of Default,
has occurred and is continuing.

         5.10     Compliance with Laws, Governance Documents and Agreements.
                  ---------------------------------------------------------
Borrower has complied and is in full compliance in all material respects with
all applicable laws, ordinances, rules, regulations, orders and other
requirements of any governmental authority or arbitrator, and with all terms and
conditions of its Governance Documents, and with each agreement binding upon or
affecting Borrower or any of its properties. Borrower is not in default with
respect to any Debt. Borrower will take all necessary actions to remain in full
compliance with such laws, ordinances, rules, regulations, orders and any other
requirements, the Governance Documents and all other agreements. Should Borrower
be deemed by any governmental authority or deem itself to be in violation of any
relevant law, ordinance, rule, regulation, orders or other requirement,
Governance Document or agreement, Borrower shall notify the Lender promptly of
such violation and take all necessary remedial actions. Without limiting the
generality of the foregoing, Borrower represents to Lender that: (1) Borrower
has previously disclosed to Lender all of Borrower's activities that involve the
use, manufacturing, storage, disposal, emission, discharge, generation or
transportation of Hazardous Wastes, Toxic Substances or other materials
regulated by Environmental Laws; (2) Borrower has complied and is in full
compliance with all Environmental Laws; (3) Borrower maintains in full force and
effect all permits required by Environmental Laws; and (4) there exists no
pending or threatened litigation, order, ruling, notice or investigation
regarding the Borrower's use, manufacturing, storage, disposal, emission,
discharge generation or transportation of Hazardous Wastes or Toxic Substances
or regarding any violation or alleged violation of any Environmental Laws.

                  ----------------------
trade names, copyrights, patents, permits, certificates, consents, approvals,
authorizations, agreements and contracts necessary to operate Borrower's
business as it currently is being operated and to own or lease Borrower's
property have been obtained, are in effect, have been complied with in all
material respects by Borrower, are free from challenge, and to the best of
Borrower's knowledge are fully assignable to the Lender for the purpose of
securing the Revolving Loan. Borrower has no knowledge and has not received any
notice to the effect that any product it manufactures or sells, or any service
it renders, or any process, method, know-how, trade secret, part or material it

Amended and Restated Loan Agreement Draft #4                                  16

<PAGE>

employs in the manufacture of any product it makes or sells or any service it
renders, or the marketing or use by it or another of any such product or
service, may infringe any trademark, trade name, copyright, patent, trade secret
or legally protected right of any other Person.

         5.12     Intellectual Property. The Borrower owns all right, title and
                  ---------------------
interest in and to all Intellectual Property used in and material to the
operation of its business or, for such Intellectual Property that is not owned,
possesses adequate licenses or other legally enforceable rights to use the same.
The Borrower has no reason to believe that any valid basis exists upon which a
claim adversely affecting any such Intellectual Property may be asserted against
the Borrower or any subsidiary. To the best knowledge of the Borrower, no Person
is infringing upon the Intellectual Property used by the Borrower or any
subsidiary material to the operation of their respective businesses. The
Borrower has taken appropriate steps to protect the secrecy, confidentiality and
value of its and all subsidiaries' rights in and to such Intellectual Property
and to prevent others from using such Intellectual Property without consent.

         5.13     Disclosure. No representation or warranty of Borrower
                  ----------
contained in this Agreement or any of the Loan Documents and no written
statement of fact furnished or to be furnished by Borrower to the Lender
pursuant to this Agreement or any of the Loan Documents, when viewed together,
contains or will contain any untrue statement of a fact material to the
financial condition of Borrower, or omits or will omit to state any material
fact necessary in order to make the statements contained herein or therein, or
furnished herewith or therewith, not misleading.

         5.14     Trade Name; Merger. During the five years immediately
                  ------------------
preceding the date of this Agreement, neither the Borrower nor any predecessor
of the Borrower has used any corporate or fictitious name other than its current
corporate name. Borrower utilizes no trade names in the conduct of its business,
except as disclosed in writing to the Lender, and has not changed its name, or
been the surviving entity in a merger or acquired any business.

         5.15     Payment of Employees and Subcontractors.  Borrower is not in
                  ---------------------------------------
default with regard to the payment of any employee or subcontractor.

                  -----
under ERISA.  Without limiting the generality of the foregoing:

                           a.       During the five-year period prior to the
date on which this representation is made or deemed made; (i) no Termination
Event has occurred, and, to the best of the Borrower's knowledge, no event or
condition has occurred or exists as a result of which any Termination Event
could reasonably be expected to occur, with respect to any Plan; (ii) no
"accumulated funding deficiency," as such term is defined in Section 302 of
ERISA and Section 412 of the Code, whether or not waived, has occurred with
respect to any Plan; (iii) each Plan has been maintained, operated and funded in
compliance with its own terms and in material compliance with the provisions of
ERISA, the Code, and any other applicable federal or state laws;

Amended and Restated Loan Agreement Draft #4                                  17

and (iv) no lien in favor of the PBGC or a Plan has arisen or is reasonably
likely to arise on account of any Plan.

                           b.       The actuarial present value of all
"benefit liabilities"  under each Single Employer Plan (determined within
the meaning of Section 401(a)(2) of the Code, utilizing the actuarial
assumptions used to fund such Plans), whether or not vested, did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the current value of the assets of such Plan
allocable to such accrued liabilities.

                           c.       Neither the Borrower nor any of its
subsidiaries nor any ERISA Affiliate has incurred, or, to the best of the
Borrower's knowledge, are reasonably expected to incur any withdrawal liability
under ERISA to any Multiemployer Plan or Multiple Employer Plan. Neither the
Borrower, any of its subsidiaries nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization (within the
meaning of Section 4241 of ERISA), is insolvent (within the meaning of Section
4245 of ERISA), or has been terminated (within the meaning of Title IV of
ERISA), and no Multiemployer Plan is, to the best knowledge of the Borrower,
reasonably expected to be in reorganization, insolvent or terminated.

                           d.       No prohibited transaction (within the
meaning of Section 406 of ERISA or Section 4975 of the Code) or breach of
fiduciary responsibility has occurred with respect to a Plan which has subjected
or may subject the Borrower or any of its subsidiaries or any ERISA Affiliate to
any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or Section
4975 of the Code, or under any agreement or other instrument pursuant to which
the Borrower or any of its subsidiaries or any ERISA Affiliate has agreed or is
required to indemnify any Person against any such liability.

Lender shall not, under any circumstances, be liable for any error or omission
or delay of any kind occurring in the settlement, collection or payment of any
Accounts or any instrument received in payment thereof or for any damage
resulting therefrom. The Lender is authorized to accept the return of the goods
represented by any of the Accounts, without notice to or consent by Borrower,
or without discharging or in any manner affecting the Revolving Loan. Upon
receipt of any returned or rejected goods, Borrower shall immediately issue and
deliver a credit memo to the Lender with respect thereto or, at the Lender's
election, Borrower may set aside such goods, mark them in the Lender's name and
hold them in trust for the benefit of the Lender at Borrower's expense and,
upon the Lender's request, shall pay the Lender the sales price thereof. If the
Lender shall request Borrower to pay the sales price of such goods and Borrower
fails to pay forthwith the sales price to the Lender, the Lender may take
possession of such goods and sell or cause such goods to be sold at public or
private sale, at such prices, to such purchasers, and upon such terms as the
Lender deems advisable. Borrower shall remain liable to the Lender for any
deficiency and shall pay the costs and expenses of such sale, including
reasonable attorneys' fees. Borrower shall use its best efforts and shall take
any and all steps necessary to collect any Accounts which are not directly
assigned to the Lender, including without limitation, the filing and pursuit of
legal action in furtherance of said collection efforts. Borrower acknowledges

cause irreparable harm to the Lender for which the Lender has no adequate
remedy at law, and agrees that the Lender shall be entitled to injunctive or
other equitable relief to compel Borrower's compliance with the provisions of
this Section.

or Section 4975 of the Code, or under any agreement or other instrument
pursuant to which the Borrower or any of its subsidiaries or any ERISA

taking possession of the Collateral, the Lender may enter the Borrower's
premises and otherwise proceed without legal process, and the Borrower shall on
the Lender's demand, promptly assemble and make the Collateral available to the
Lender at a place designated by the Lender. The Lender shall be entitled to
immediate possession of all books and records evidencing or pertaining to any
of the Collateral;

                           c.       Notify any or all Customers to make any
Payments due to Borrower from such Customers directly to the Lender. To

all mail addressed to Borrower and take therefrom any Payments on or proceeds
of Accounts; (ii) take over Borrower's post office boxes or make such other

any error of judgment or mistake of fact or law of any such attorney-in-fact
unless such acts are due to willful misconduct. This power, being coupled with
an interest and given to secure an obligation, is irrevocable so long as the
Revolving Loan remains unsatisfied, or any Loan Document remains effective, as
solely determined by the Lender;

                           d.       In the Lender's own name, or in the name of
Borrower, demand, collect, receive, sue for and give receipts and releases for,

circumstances, be liable for any error or omission or delay of any kind
occurring in the settlement, collection or payment of any Accounts or any
instrument received in payment thereof or for any damage resulting therefrom
unless caused by Lender's willful misconduct;

receiver and agreeing not to oppose any such appointment. Any receiver so
appointed shall have such powers as may be conferred by the appointing

Lender is authorized to exercise by the Loan Documents, and shall have the
right to incur such obligations and to issue such certificates therefor as the
appointing authority shall authorize;

                           h.       Take any other action which the Lender
deems necessary or desirable to protect and realize upon its security interest

shall be entitled to specific performance, an injunction or other equitable
relief to enforce the Borrower's obligations under this Agreement; and

sale or other disposition of the Collateral shall be applied in the following

                  ------------

validity prescribed by law, then the obligation to be fulfilled or performed
shall be reduced to the limit of such validity; and if any clause or

Amended and Restated Loan Agreement Draft #4                                 31

<PAGE>

provision contained in any Loan Document operates or would operate
prospectively to invalidate any Loan Document, in whole or in part, then such
clause or provision only shall be held ineffective, as though not herein or
therein contained, and the remainder of the Loan Documents shall remain
operative and in full force and effect.

         10.5     Survival. It is the express intention and agreement of the
                  --------
parties hereto that all covenants, agreements, statements, representations,
warranties and indemnities made by Borrower in the Loan Documents shall survive
the execution and delivery of the Loan Documents and the making of all Advances
and extensions of credit thereunder.

         10.6     Waivers. No waiver by the Lender of, or consent by the Lender
                  -------
to, a variation from the requirements of any provision of the Loan Documents
shall be effective unless made in a written instrument duly executed on behalf
of the Lender by its duly authorized officer, and any such waiver shall be
limited solely to those rights or conditions expressly waived.

         10.7     Rights Cumulative. The rights and remedies of the Lender
                  -----------------
described in any of the Loan Documents are cumulative and not exclusive of any
other rights or remedies which the Lender or the then holder of the Revolving
Note otherwise would have at law or in equity or otherwise. No notice to or
demand on Borrower in any case shall entitle Borrower to any other notice or
demand in similar or other circumstances.

         10.8     Entire Agreement; Modification; Benefit. This Agreement, the
                  ---------------------------------------
exhibits hereto, and the other Loan Documents constitute the entire agreement of
the parties hereto with respect to the matters contemplated herein, supersede
all prior oral and written agreements with respect to the matters contemplated
herein, and may not be modified, deleted or amended except by written instrument
executed by the parties. All terms of this Agreement and of the other Loan
Documents shall be binding upon, and shall inure to the benefit of and be
enforceable by, the parties hereto and their respective successors and assigns;
however, Borrower may not assign or transfer any of its rights or obligations
hereunder without the prior written consent of the Lender. In the event of any
conflict between the terms of this Agreement and the terms of the other Loan
Documents, the terms of this Agreement shall control.

         10.9     Setoff. In addition to any rights or remedies of the Lender
                  ------
provided by law, upon the occurrence of any Event of Default hereunder, or any
event or circumstance which, with the giving of notice or the passage of time or
both, would constitute an Event of Default hereunder, the Lender is irrevocably
authorized, at any time or times without prior notice to Borrower, to set off,
appropriate and apply any and all deposits, credits, indebtedness or claims at
any time held or owing by the Lender to or for the credit or the account of
Borrower, in such amounts as the Lender may elect, against and on account of the
obligations and liabilities of Borrower to the Lender hereunder or under any of
the other Loan Documents, whether or not the Lender has made any demand for
payment, and although such obligations and liabilities may be contingent or
unmatured.

         10.10    Construction. This Agreement and the other Loan Documents, the
                  ------------
rights and obligations of the parties hereto, and any claims or disputes
relating thereto shall be governed by and construed in accordance with the laws
of the Commonwealth of Virginia (excluding the

Amended and Restated Loan Agreement Draft #4                                 32

choice of law rules thereof).  Each party hereto hereby acknowledges that all
parties hereto participated equally in the negotiation and drafting of this
Agreement and that, accordingly, no court construing this Agreement shall
construe it more stringently against one party than against the other.

         10.11    Pronouns. All pronouns and any variations thereof shall be
                  --------
deemed to refer to the masculine, feminine, neuter, singular or plural, as the
identity of the Person may require.

         10.12    Headings. Article, section and subsection headings contained
                  --------
in this Agreement are inserted for convenience of reference only, shall not be
deemed to be a part of this Agreement for any purpose, and shall not in any way
define or affect the meaning, construction or scope of any of the provisions
hereof.

         10.13    Payments. If any payment or performance of any of the
                  --------
obligations under this Agreement or any of the other Loan Documents becomes due
on a day other than a Business Day, the due date shall be extended to the next
succeeding Business Day, and interest thereon (if applicable) shall be payable
at the then applicable rate during such extension.

         10.14    Accounting Terms. All accounting terms used herein which are
                  ----------------
not otherwise expressly defined in this Agreement shall have the meanings
respectively given to them in accordance with GAAP in effect on the date of this
Agreement. Except as otherwise provided herein, all financial computations made
pursuant to this Agreement shall be made in accordance with GAAP, consistently
applied, and all balance sheets and other financial statements shall be prepared
in accordance with GAAP, consistently applied. Except as otherwise provided
herein, whenever reference is made in any provision of this Agreement to a
balance sheet or other financial statement or the information depicted therein
for performing a financial computation, such terms shall mean the most recent
consolidated balance sheet or other financial statement received by the Lender
pursuant to the terms hereof.

         10.15    Execution. To facilitate execution, this Agreement and any of
                  ---------
the other Loan Documents may be executed in as many counterparts as may be
required; and it shall not be necessary that the signature of, or on behalf of,
each party, or the signatures of all persons required to bind any party, appear
on each counterpart; but it shall be sufficient that the signature of, or on
behalf of, each party, or the signatures of the persons required to bind any
party, appear on one or more of the counterparts. All counterparts shall
collectively constitute a single agreement. It shall not be necessary in making
proof of this Agreement or any other Loan Document to produce or account for
any particular number of counterparts; but rather any number of counterparts
shall be sufficient so long as those counterparts contain the respective
signatures of, or on behalf of, all of the parties hereto.

         10.16    Consent to Jurisdiction. Subject to any provision of this
                  -----------------------
Agreement requiring that disputes be submitted to arbitration, the
Borrower irrevocably consents 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 Agreement or
the other Loan Documents. 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, or 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.

         10.17    Service of Process. The Borrower consents to process being
                  ------------------
served in any suit, action or proceeding by mailing a copy thereof by
registered or certified mail postage prepaid, return receipt requested, to the
Borrower's address specified in or designated in this Agreement. The Borrower
agrees that such service (i) shall be deemed in every respect effective service
of process upon the Borrower in any such suit, action or proceeding and (ii)
shall, to the fullest extent permitted by law, be taken and held to be valid
personal service upon and personal delivery to the Borrower. Nothing in this
Section shall affect the right of the Lender to serve process in any manner
permitted by law, or limit any right that the Lender may have to bring
proceedings against the Borrower in the courts of any jurisdiction or to
enforce in any lawful manner a judgment obtained in one jurisdiction in any
other jurisdiction.

         10.18    Sale of Loan Documents; Disclosure of Information. Borrower
                  -------------------------------------------------
hereby consents to and agrees that Lender may disclose to any Person any and all
information connected with or related to the Revolving Loan or other Loan
Documents for the purpose of selling or assigning any rights of Lender in the
Loan Documents. The information which may be disclosed by Lender includes but is
not limited to all Loan Documents, credit files and correspondence files and all
other writings and oral communications which Lender wishes to disclose, in its
sole and absolute discretion. Borrower also hereby consents to and agrees that
Lender may sell or assign any rights of Lender in any or all of the Loan
Documents pursuant to such terms and conditions as may be acceptable to Lender
in its sole and absolute discretion, to any interested Person, and nothing in
this Agreement or the other Loan Documents shall prevent, delay or otherwise
impede or effect the right of Lender to immediately sell or assign any rights of
Lender in the Loan Documents on such terms as it deems acceptable.

         10.19    ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE
                  -----------
