                             II. REVOLVING FACILITY

         2.1      Revolving Credit. Until December 13, 2004, the Revolving
Lenders severally agree to advance funds for general corporate purposes not to
exceed the amount shown on Appendix I attached hereto, as amended from time to
time (the "Base Revolving Credit Facility"), to the Borrower on a revolving
credit basis.

         Such Advances shall be made on a pro rata basis by the Revolving
Lenders, based on the maximum Advance limits and applicable percentages for each
Revolving Lender as shown on Appendix I attached hereto, as amended from time to
time; provided, however, that each Revolving Lender's Commitment is several and
not joint or joint and several.

         The Borrower shall not be entitled to any Advance hereunder if, after
the making of such Advance, the Principal Loan Amount would exceed the then
current Base Revolving Credit

                                     - 13 -

<PAGE>

Facility after giving effect to the requested Advance. Nor shall the Borrower be
entitled to any further Advances hereunder after the occurrence and during the
continuation of any Event of Default or Potential Event of Default including a
default of the Leverage Ratio covenant under Section 4.19, or if the Borrower's
representations and warranties hereunder are not true and correct in all
material respects as of the time of the requested Advance. Advances shall be
made, on the terms and conditions of this Agreement, upon the Borrower's
request. Requests shall be made by 11:00 a.m. Omaha time on the Business Day
prior to the requested date of the Advance. Requests shall be made by
presentation to FNB-O of a drawing certificate in the form of Exhibit B. The
Borrower's obligation to make payments of principal and interest on the
foregoing revolving credit indebtedness shall be further evidenced by the Notes.
FNB-O shall promptly transmit a copy of each such Advance request to the other
Revolving Lenders. Each Revolving Lender shall remit to FNB-O its Commitment
percentage times the amount of the Advance request, subject to the conditions
specified hereunder. Such remittance shall be transferred to FNB-O on the same
Business Day as to requests received by such Revolving Lender before 12:00 noon
of a Business Day, and as to requests received thereafter, on the next Business
Day.

         2.2      Revolving Credit Fees.

                  (a) The Borrower shall pay to the Revolving Lenders a
         commitment fee equal to 1/4 of 1% (.0025) of the average unused
         facility, payable quarterly in arrears. Such fee shall accrue from the
         first day of each calendar quarter and shall be payable in arrears on
         the tenth (10th) day of the month following the end of each calendar
         quarter; provided, however, that the commitment fee for the calendar
         quarter ending December 31st, 2003 shall accrue from December 15, 2003.
         Such fee shall be paid to the Agent and based on the average unused
         portion of each Revolving Lender's Commitment during the applicable
         quarter. FNB-O shall distribute to each Revolving Lender its pro rata
         share of such fees based on the maximum Advance limits set forth above.

                  (b) The Borrower shall also pay a closing fee to each
         Revolving Lender as set forth in Appendix I attached hereto, such fees
         to be payable at closing.

                  (c) All fees hereunder shall accrue based on a year of 360
         days, and for actual days elapsed.

         2.3      Interest on Revolving Credit. Interest shall accrue on the
Principal Loan Amount outstanding from time to time at a variable rate per annum
(the "Revolving Credit Rate") equal to the lesser of (a) the National Prime Rate
minus the Applicable Margin, or (b) the LIBOR Rate plus the Applicable Margin.
Such rate shall fluctuate monthly based on changes in such rates on the first
day of each month. All interest under the Notes shall accrue based on a year of
360 days, and for actual days elapsed. Interest for any month shall be due no
later than the tenth day of the following month. Notwithstanding anything to the
contrary elsewhere herein, after an Event of Default has occurred and is
continuing, interest shall accrue on the entire outstanding balance of principal
and interest on all indebtedness hereunder at a fluctuating rate per annum equal
to the Default Rate.

         2.4      Payments. On the next succeeding Business Day after the end of
any Fiscal Month the Borrower shall repay the amount, if any, outstanding on the
Notes which in the

                                     - 14 -

<PAGE>

aggregate exceeds the amount of the Base Revolving Credit Facility to be in
place on the next succeeding Business Day following such Fiscal Month and,
within three (3) Business Days after the end of any Fiscal Month in which the
Borrower is not in compliance with the Leverage Ratio covenant in Section 4.19,
such amount necessary to bring the Borrower into compliance with Section 4.19.
The balance of the loan on December 13, 2004, if any, shall be due on the
Termination Date. All obligations of the Borrower under the Notes and under the
other Operative Documents shall be payable in immediately available funds in
lawful money of the United States of America at the principal office of FNB-O in
Omaha, Nebraska or at such other address as may be designated by FNB-O in
writing. In the event that a payment day is not a Business Day, the payment
shall be due on the next succeeding Business Day.

         2.5      Prepayments. The Borrower may at any time prepay the Principal
Loan Amount, in whole or in part, outstanding under the Notes if the Borrower
has given the Agent at least one (1) Business Day's prior written notice of its
intention to make such prepayment. Any such prepayment may be made without
penalty. All such prepayments (other than the prepayments under Section 8.1)
shall be made pro rata among the Revolving Lenders based on their respective pro
rata share of the amounts outstanding on the Notes. No such prepayment shall
reduce the Base Revolving Credit Facility.

         2.6      Security. All obligations of the Borrower hereunder and under
the Operative Documents, including, without limitation, the Borrower's
obligations to make payments of principal and interest on the Notes and to pay
all amounts due in connection with the Letters of Credit, shall be secured by a
first security interest in the Collateral, as more specifically described in the
Security Agreements and the Pledge Agreements, subject to liens permitted
thereunder. All references in the Security Agreements and the Pledge Agreements
to the "Revolving Credit Agreement" shall mean this Agreement as amended from
time to time.

         2.7      Letter of Credit Facility. Subject to and upon the terms and
conditions herein set forth, the Borrower may request and FNB-O on behalf of the
Revolving Lenders shall issue from time to time for the account of the Borrower
or one or more of its Subsidiaries letters of credit (the "Letters of Credit");
provided, however, FNB-O shall have no obligation to issue any such Letter of
Credit unless at such time the Borrower meets all the conditions for an Advance
under the Base Revolving Credit Facility and, after such issuance, the aggregate
Letter of Credit Amount outstanding will not exceed $15,000,000 and the
Principal Loan Amount will not exceed the then available Base Revolving Credit
Facility and no Potential Event of Default or Event of Default shall have
occurred or be continuing, including a default of the Leverage Ratio covenant
under Section 4.19, all as more specifically set forth in this Agreement. The
Revolving Lenders shall be obligated to fund pro rata according to their
respective pro rata percentages shown in Section 2.1 of this Agreement any draws
on such Letters of Credit and shall be entitled to share pro rata in the Letter
of Credit Fees and reimbursement amounts received in connection with such
Letters of Credit. The Letter of Credit Amount outstanding at any time shall
operate to reduce amounts available to be drawn under the Base Revolving Credit
Facility by such sum, and shall be deemed to be outstanding for purposes of
calculating the commitment fee under Section 2.2 (a) of this Agreement. No
Letter of Credit shall have a maturity date occurring later than the Termination
Date of this Agreement; provided, however, FNB-O, upon five days prior written
notice to the other Revolving Lenders, may issue one or more Letters of Credit
in an aggregate amount not to exceed $1,000,000.00 in Letters of Credit under
this Agreement with a maturity

                                     - 15 -

<PAGE>

occurring after the Termination Date of this Agreement (a "Non-Conforming Letter
of Credit"), but no other Revolving Lender shall be obligated to fund any draws
on such Non-Conforming Letters of Credit and shall not be entitled to share pro
rata in the Letter of Credit Fees and reimbursement amounts received in
connection therewith unless such Revolving Lender elects in writing to
participate in such Non-Conforming Letters of Credit after receipt of notice
from FNB-O. Except as provided in the preceding sentence, any such
Non-Conforming Letters of Credit shall in all other respects be deemed a "Letter
of Credit" under this Agreement. Any reference in this Agreement (including
without limitation Articles VII and VIII) to a "loan" or "loans" made under this
Agreement shall include the Letters of Credit, and, for purposes of Article VII,
amounts outstanding under the Notes shall be deemed to include amounts available
to be drawn and unreimbursed drawings under issued and outstanding Letters of
Credit.

         2.8      Letter of Credit Documents. Prior to the issuance by FNB-O of
any Letters of Credit, the Borrower and, if requested by FNB-O, the applicable
Subsidiary, shall execute and deliver to FNB-O an application and continuing
letter of credit agreement, such agreements to be in the form provided by FNB-O,
as may be amended from time to time for general use in connection with letters
of credit issued by FNB-O.

         2.9      Letter of Credit Fees. In addition to all costs incurred by
FNB-O in the issuance and enforcement of the Letters of Credit which are to be
reimbursed by the Borrower in accordance with the application and continuing
letter of credit agreement executed in connection with each Letter of Credit,
the Borrower shall pay to the Agent a letter of credit fee (the "Letter of
Credit Fee") equal to two percent (2.0%) per annum of the amounts available to
be drawn under outstanding Letters of Credit, such fee to be based on the
average Letter of Credit Amount outstanding during such quarter; provided,
however, that at any time that an Event of Default has occurred and is
continuing under the Agreement, such fee shall be equal to five percent (5%) per
annum. Such fee shall accrue from the first day of each calendar quarter and
shall be payable in arrears on the tenth (10th) day of the month following the
end of each calendar quarter; provided, however, that the Letter of Credit Fee
for the calendar quarter ending December 31st, 2003 shall accrue from December
15, 2003. Interest shall accrue on amounts drawn under any Letter of Credit,
until such amount is reimbursed, at the then current rate for amounts
outstanding under the Notes and, for any period that such draw remains
unreimbursed more than two Business Days after such draw, at the Default Rate.
Agent at its sole option shall have the right to make an advance under the Base
Revolving Credit Facility to repay any unreimbursed draws under a Letter of
Credit. In addition, the Borrower shall pay such other administrative fees,
including a fee for opening the Letter of Credit, as are agreed in writing
between FNB-O and the Borrower. Amounts received by FNB-O for opening a
Non-Conforming Letter of Credit or as administrative fees with respect to any
Letter of Credit remain the property of FNB-O and shall not be shared pro rata
with the Revolving Lenders. Letter of Credit Fees shall accrue based on a year
of 360 days, and for actual days elapsed.

         2.10     Voluntary Reduction or Termination of Base Revolving Credit
Facility. The Borrower may from time to time on at least two (2) Business Days'
prior written notice to the Agent (which shall promptly advise each Revolving
Lender thereof) permanently reduce the amount of the Base Revolving Credit
Facility to an amount not less than the then-outstanding Principal Loan Amount;
provided, however, that any such reduction shall be in an aggregate minimum
amount of $5,000,000.00 and integral multiples of $1,000,000.00 in excess of
that

                                     - 16 -

<PAGE>

amount. Concurrently with any reduction of the amount of the Base Revolving
Credit Facility to zero, as provided in the first sentence of this Section 2.10,
the Borrower shall pay all interest on the Advances and all fees. All reductions
of the Base Revolving Credit Facility shall reduce the Commitments pro rata
among the Revolving Lenders.

         2.11     Payment Receipt. Payments received before 12:00 noon on any
Business Day will be credited the same Business Day. Payments received after
12:00 noon on any Business Day will be credited the next Business Day.

                       III. REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants that as of the date hereof and as
of the date of each and every request for an Advance hereunder, the following
are and shall be true and correct:

         3.1      Corporate Existence. Each of the Borrower and its Subsidiaries
is a corporation or limited liability company duly organized, validly existing
and in good standing under the laws of the state of its organization and duly
qualified and in good standing in all states where it is doing business except
where the failure to be so qualified would not have a material adverse effect on
it and its Subsidiaries taken as a whole, and it has full corporate or limited
liability company power and authority to own and operate its properties and to
carry on its business.

         3.2      Corporate Authority. Each of the Borrower and the Guarantors
has full corporate power, authority and legal right to execute, deliver and
perform the Operative Documents to which it is a party, and all other
instruments and agreements contemplated hereby and thereby, and to perform its
obligations hereunder and thereunder; and such actions have been duly authorized
by all necessary corporate action, and are not in conflict with any applicable
law or regulation, or any order, judgment or decree of any court or other
governmental agency or instrumentality or its articles of incorporation or
bylaws, or with any provisions of any indenture, contract or agreement to which
it or any of its Subsidiaries is a party or by which it or any of its
Subsidiaries or any of its or their property may be bound.

         3.3      Validity of Agreements. The Operative Documents of the
Borrower and each of the Guarantors have been duly authorized, executed and
delivered and constitute their legal, valid and binding agreements, enforceable
against the Borrower and the Guarantors in accordance with their respective
terms (except to the extent that enforcement thereof may be limited by any
applicable bankruptcy, reorganization, moratorium or similar laws now or
hereafter in effect, or by principles of equity).

         3.4      Litigation. Neither the Borrower nor any Subsidiary is a party
to any pending lawsuit or proceeding before or by any court or governmental body
or agency, which is likely to have a material adverse effect on (a) the
Borrower's ability or any Guarantor's ability to perform its obligations under
its Operative Documents or (b) a Subsidiary's ability to pay dividends to the
Borrower, to the extent that such impaired ability would have a material adverse
effect on the Borrower and its Subsidiaries, taken as a whole; nor is the
Borrower aware of any threatened lawsuit or proceeding, to which it or any
Subsidiary may become a party or of any investigation of any Court or
governmental body or agency into its affairs, which if instituted would have a
material adverse effect upon the Borrower's ability or any Guarantor's ability
to perform its

                                     - 17 -

<PAGE>

obligations under its Operative Documents or a Subsidiary's ability to pay
dividends to the Borrower, to the extent that such impaired ability would have a
material adverse effect on the Borrower and its Subsidiaries taken as a whole.

         3.5      Governmental Approvals. The execution, delivery and
performance by the Borrower and the Guarantors of the Operative Documents do not
require the consent or approval of, the giving of notice to, the registration
with, or the taking of any other action in respect of, any federal, state or
other governmental authority or agency other than as contemplated herein and
therein.

         3.6      Defaults Under Other Documents. Neither the Borrower nor any
Subsidiary is in default or in violation (nor has any event occurred which, with
notice or lapse of time or both, would constitute a default or violation) under
any document or any agreement or instrument to which it may be a party or under
which it or any of its properties may be bound, the result of which would have a
material adverse effect upon the Borrower's ability or any Guarantor's ability
to perform its obligations under its Operative Documents or a Subsidiary's
ability to pay dividends to the Borrower and/or the Guarantors, to the extent
that such impaired ability would have a material adverse effect on the Borrower
and its Subsidiaries, taken as a whole.

         3.7      Judgments. There are no outstanding or unpaid judgments (which
are not adequately bonded) of the Borrower or any Subsidiary which would have a
material adverse effect upon the Borrower's ability or any Guarantor's ability
to perform its obligations under its Operative Documents or a Subsidiary's
ability to pay dividends to the Borrower and/or the Guarantors, to the extent
that such impaired ability would have a material adverse effect on the Borrower
and its Subsidiaries, taken as a whole.

         3.8      Compliance with Laws. Neither the Borrower nor any Subsidiary
is in violation of any laws, regulations or judicial or governmental decrees in
any respect which would have any material adverse effect upon the validity or
enforceability of any of the terms of the Borrower or any Guarantor's Operative
Documents or which would have a material adverse effect upon the Borrower's
ability or any Guarantor's ability to perform its obligations under its
Operative Documents or a Subsidiary's ability to pay dividends to the Borrower
and/or the Guarantors, to the extent that such impaired ability would have a
material adverse effect on the Borrower and its Subsidiaries, taken as a whole.

         3.9      Taxes. All tax returns of the Borrower and its Subsidiaries
for material taxes required to be filed have been filed or extensions permitted
by law have been obtained; all taxes of the Borrower and its Subsidiaries of a
material nature and which are due and payable as reflected on such returns have
been paid, other than taxes which are due but for which only a nominal late
payment penalty is payable and for which the taxing authority is not yet
entitled to enforce its remedies for payment thereof and other than taxes being
contested in good faith and with respect to which adequate reserves have been
established; and no material amounts of taxes of the Borrower and its
Subsidiaries not reflected on such returns are payable.

         3.10     Collateral. The Borrower and each Guarantor have good title to
the Collateral and the Collateral is free from all liens, encumbrances or
security interests, except for Permitted Liens and except as disclosed on
Exhibit D attached hereto. The Borrower is a Delaware

                                     - 18 -

<PAGE>

corporation with its principal place of business, chief executive office, and
the principal place where it keeps its records concerning the Collateral at 4211
South 102nd Street, Omaha, Nebraska 68127.

         3.11     Pension Benefits. Neither the Borrower nor any Subsidiary
maintains a Plan as defined in Section 3(3) of ERISA, or each such entity is in
compliance with the minimum funding requirements with respect to any such Plan
maintained by it to the extent applicable, and it has not incurred any material
liability to the Pension Benefit Guaranty Corporation (other than liability for
premiums) or otherwise under ERISA in connection with any such Plan.

         3.12     Margin Regulations. No part of the proceeds of any Advance
hereunder shall be used for any purpose that violates, or which is inconsistent
with, the provisions of Regulation T, U or X of the Board of Governors of the
Federal Reserve System of the United States.

         3.13     Financial Condition. The financial condition of the Borrower
and its Subsidiaries is fairly presented in all material respects in the most
recent financial statement which has been provided to the Agent and such
financial statement does not contain any untrue statements of a material fact or
omit to state any material fact necessary to make the statement therein not
misleading in light of the circumstances under which it was made. No material
adverse change has occurred since the date of such financial statement.

                                  IV. COVENANTS

         The Borrower hereby covenants that:

         4.1      Financial Reports.

                  (a) Within thirty (30) days after the end of each month, the
         Borrower, at its sole expense, shall furnish the Agent a consolidated
         balance sheet, a statement of earnings of the Borrower and its
         consolidated Subsidiaries, and a statement of cash flows of the
         Borrower and its consolidated Subsidiaries, all such financial
         statements to be prepared in accordance with GAAP consistently applied
         and certified as fairly presenting, in all material respects, the
         financial condition of the Borrower and its consolidated Subsidiaries,
         subject to normal changes resulting from year-end audit adjustments, by
         the chief financial officer of the Borrower.

                  (b) Within ninety (90) days after the close of the Borrower's
         fiscal year, the Borrower, at its sole expense, shall furnish the
         Agent: (i) a consolidated balance sheet, a statement of earnings of the
         Borrower and its consolidated Subsidiaries and a statement of cash
         flows of the Borrower and its consolidated Subsidiaries, certified by
         Deloitte & Touche LLP, or other comparable nationally recognized
         independent certified public accountants, that such financial reports
         fairly present in all material respects the financial condition of the
         Borrower and its consolidated Subsidiaries and have been prepared in
         accordance with GAAP consistently applied; and (ii) a certificate from
         such accountants certifying that in making the requisite audit for
         certification of the Borrower's financial statements, the auditors
         either (1) have obtained no knowledge, and are not otherwise aware of,
         any condition or event which constitutes an Event of Default or which
         with the passage of time or the giving of notice would constitute an
         Event of Default under this

                                     - 19 -

<PAGE>

         Agreement; or (2) have discovered such condition or event, as
         specifically set forth in such certificate, which constitutes an Event
         of Default or which with the passage of time or the giving of notice
         would constitute an Event of Default under such sections. The auditors
         shall not be liable to the Revolving Lenders by reason of the auditors'
         failure to obtain knowledge of such event or condition in the ordinary
         course of their audit unless such failure is the result of negligence
         or willful misconduct in the performance of the audit.

                  (c) Within thirty (30) days after submission to the Securities
         and Exchange Commission, the Borrower shall provide to the Agent copies
         of its Forms 10K and 10Q, as submitted to the Securities and Exchange
         Commission during the term of this Agreement, plus consolidating
         statements of the Borrower and its consolidated Subsidiaries, including
         a balance sheet, a statement of earnings and a statement of cash flows.

                  (d) Within thirty (30) days after the end of each month, the
         Borrower shall cause Ameritrade Online and iClearing to provide to the
         Agent the FOCUS report of Ameritrade, Inc. and iClearing for such
         month.

                  (e) Within thirty (30) days after the end of each month, the
         Borrower, at its sole expense, shall furnish the Agent a liquidity
         certificate of the chief financial officer of the Borrower in the form
         of Exhibit C attached hereto, setting forth such information (including
         detailed calculations) sufficient to verify the conclusions of such
         officer after due inquiry and review.

                  (f) The Borrower shall provide the Agent with such other

                  4.2      Corporate Structure and Assets.

                  (a) The Borrower shall not, and shall not permit any Guarantor

         provided in clause (b) below.

                 (c) The Borrower shall not, and shall not permit any Guarantor
         to, sell any assets, other than in the ordinary course of business, in
         an aggregate amount greater than five million dollars ($5,000,000);
         provided, however, that if the aggregate net cash proceeds obtained by
         the Borrower or any Guarantor through the sale of such assets exceeds
         one million dollars ($1,000,000), then the amount of such net cash
         proceeds exceeding one million dollars ($1,000,000) shall be used to
         repay the amount, if any, outstanding on the Notes. Notwithstanding the
         foregoing sentence, the following sales of assets are permitted
         hereunder, without any necessity of prepaying the Notes with the
         proceeds of such sales: (i) items that are obsolete or no longer
         necessary for operation of the business, (ii) Ameritrade Online's
         interest in Comprehensive Software Systems, Ltd., (iii) Ameritrade
         Online's interest in the NITE Stock, (iv) sales of assets to the
         Borrower or a Guarantor or another Subsidiary, (v) the interest of the
         Borrower and/or its Subsidiaries in Watcher Technologies LLC, (vi) the
         transaction with General Electric Capital Corp. related to Datek's
         building located in Jersey City, New Jersey, and (vii) the interest of
         the Borrower and/or its Subsidiaries in TradeCast, Inc., Bidwell &
         Company, Inc. and/or iClearing. Notwithstanding the foregoing
         prepayment requirements, any such prohibited sale shall remain a
         violation of this Agreement. For purposes of this Section 4.2(c), "net
         cash proceeds" shall mean the amount in cash or cash equivalents
         received from the sale after taxes and after payment of all costs and
         expenses incurred in connection with the sale, including brokerage or
         similar fees.

                  (d) In addition, the Borrower and the Guarantors shall not
         engage in any business materially different from that in which they are
         presently engaged and businesses reasonably related thereto without the
         prior written consent of the Requisite Revolving Lenders, which consent
         shall not be unreasonably withheld.

                  (e) The Borrower shall at all times maintain a one hundred
         percent (100%) ownership interest in Ameritrade Online and Datek.

         4.3      Indebtedness. The Borrower shall not, and shall not permit any
Guarantor to, have any Indebtedness other than Permitted Indebtedness.

be used for any purpose that violates, or which is inconsistent with, the
provisions of Regulation T, U or X of the Board of Governors of the Federal
Reserve System of the United States.

         4.5      Notice of Occurrences. The Borrower shall give to the Agent
written notification (promptly after the Borrower becomes aware thereof) of the
existence or occurrence of:

                  (a) the occurrence of an Event of Default or Potential Event
         of Default hereunder;

                  (b) any proceedings instituted by or against the Borrower or
         any Subsidiary in any federal, state or local court or before any
         governmental body or agency, or before any arbitration board, or any
         such proceedings threatened against the Borrower or any Subsidiary by
         any governmental agency, or any change in law or regulation applicable
         to the Borrower or one or more of its Subsidiaries, which event alone
         or in the aggregate is, in the Borrower's reasonable judgment, likely
         to have a material adverse effect upon the

                                     - 21 -

<PAGE>

         Borrower's ability or a Guarantor's ability to perform its obligations
         under its Operative Documents;

         money under any agreement or instrument which is material to the
         Borrower or any Subsidiary to which such entity is a party or by which
         it or any of its property may be bound, and which default or event of
         default would have a material adverse effect upon the Borrower's
         ability or a Guarantor's ability to perform its obligations under its
         Operative Documents;

                  (d) the commencement of any proceeding under the Federal
         Bankruptcy Code or similar law affecting creditor's rights by or
         against the Borrower or any Subsidiary; and

                  (e) pending or threatened litigation exists against the
         Borrower or any Subsidiary with a prayer for damages in excess of
         $10,000,000 or for any other relief which is likely to have a material
         adverse effect upon the Borrower's ability or a Guarantor's ability to
         perform its obligations under its Operative Documents.

         4.6      Distributions.

                  (a) The Borrower shall not declare any dividends or make any
         cash distribution in respect of any shares of its capital stock or
         warrants of its capital stock, without the prior written consent of the
         Requisite Revolving Lenders; provided, however, that the Borrower may
         declare stock dividends.

                  (b) The Borrower shall not redeem stock or Subordinated Debt
         at any time at which an Event of Default or Potential Event of Default

         Minimum Liquid Assets as of the date of distribution.

                  (c) Neither the Borrower nor any Subsidiary will enter into
         any agreements limiting a Subsidiary's ability to make dividends to the
         Borrower which are more restrictive than the net capital rule
         promulgated under Section 15(c) of the Exchange Act.

         4.7      Compliance with Law and Regulations. The Borrower and each
Subsidiary shall comply in all material respects with all applicable federal and
state laws and regulations except when the failure to so comply would not have a
material adverse effect on the Borrower's business.

Insurance.

                  (a) The Borrower and each Subsidiary shall maintain its

         its corporate or limited liability company form of existence as is
         necessary for the continuation of its business in substantially the
         same form, except where such failure to do so with respect to any
         Subsidiary would not have a material adverse effect on the ability of
         the Borrower or of any Guarantor to perform its obligations under the
         Operative Documents.

                  (d) The Borrower and each Subsidiary shall pay all taxes,

favor of FNB-O, as agent for the Revolving Lenders; provided, however, that the
Borrower shall not pledge to Agent any investment property or equity securities
issued by any Material Subsidiary of the Borrower that is organized under the

thereof) in excess of sixty-five percent (65%) of the total voting power of all
equity securities of such Material Subsidiary. The Borrower shall cause a

appropriate proceeding and with respect to which adequate reserves in accordance
with GAAP have been established.

         Subsidiary is required to pay as contributions thereto, or (iii) permit
         to exist any accumulated funding deficiency, whether or not waived,

         Plan, if, in the case of any of subdivision (i), (ii) or (iii) above,
         such penalty or tax, or the failure to make such payment, or the
         existence of such deficiency, as the case may be, could have a material
         adverse effect on (a) the Borrower's or its Subsidiaries' abilities to
         conduct their business, (b) a Subsidiary's ability to pay dividends to
         the Borrower, to the extent that such impaired ability would have a

         perform its obligations under the Operative Documents; or

         4.20 (but solely if a lien has attached to assets of the Borrower or

         to comply with any requirement or restriction contained in any

         source.

                  (f) The occurrence of a default or a breach of any of the

         from the date of such entry during which the judgment is not discharged

         the Borrower, to the extent that such impaired ability would have a

                                     - 28 -

<PAGE>

         Borrower's ability or any Guarantor's ability to perform its

                  (k) Any litigation has been filed against the Borrower or one

         obligations under this Agreement or any of the Operative Documents.

         6.2      Remedies. If an Event of Default occurs and is continuing,
upon the election of the Requisite Revolving Lenders, the entire unpaid
principal amount under the Notes, together with interest accrued thereon, shall
become immediately due and payable without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived, the Commitments of
the Revolving Lenders hereunder shall terminate, and the Revolving Lenders may
exercise their rights under the other Operative Documents or the Notes,
including, without limitation, under the Security Agreements and the Pledge
Agreements. Upon the occurrence of an Event of Default described in Section
6.1(h)(1) or (2) hereof, acceleration under this Section 6.2 shall occur
automatically without the election, declaration, notice or other act on the part
of any of the Revolving Lenders. In addition, the Revolving Lenders shall have
such other remedies as are available at law and in equity. Remedies under this
Agreement, the Operative Documents, and the Notes are cumulative. Any waiver
must be in writing by the Revolving Lenders and no waiver shall constitute a
waiver as to any other occurrence which constitutes an Event of Default or as to
any party not specifically included in such written waiver.

                         VII. INTER-CREDITOR AGREEMENTS

         7.1      FNB-O as Servicer. FNB-O will act as sole servicer of the
loans evidenced by the Notes. For purposes of this Article VII, the term Event
of Default means any Event of Default hereunder. FNB-O will enforce, administer
and otherwise deal with the loans made by the Revolving Lenders in accordance
with safe and prudent banking standards employed by FNB-O in the case of the
loan made by FNB-O. Without limiting the generality of the foregoing, FNB-O
will, on its own behalf and on behalf of the Revolving Lenders: (i) maintain
originals of the Operative Documents (excluding the Notes); (ii) receive
requests for Advances from the Borrower, promptly transmit the same to the
Revolving Lenders and make such Advances on behalf of the Revolving Lenders
(provided that FNB-O is assured of reimbursement therefor by the other Revolving
Lenders for their pro rata shares); (iii) receive payments and prepayments from
the Borrower and apply such payments as provided in Section 7.2; (iv) receive
notices and financial statements from the Borrower and send copies thereof to
the Revolving Lenders if FNB-O has reasonable cause to believe that such
Revolving Lenders have not received such notice or financial statement from
another source; and (v) advise the Revolving Lenders of the occurrence of any
Event of Default of which FNB-O obtains actual knowledge. The Revolving Lenders
agree not to attempt to take any action against the Borrower under the Operative
Documents or the Notes, or with respect to the indebtedness evidenced thereby
without FNB-O's consent unless the Requisite Revolving Lenders shall have
requested FNB-O to take specific

                                     - 29 -

<PAGE>

action against the Borrower and FNB-O shall have failed to do so within a
reasonable period after receipt of such request. All actions, consents, waivers
and approvals by the Revolving Lenders shall be deemed taken or given and
amendments hereto deemed agreed to if the Requisite Revolving Lenders shall have
indicated their consent thereto. Notwithstanding the foregoing, approval of a
Revolving Lender shall be required for: (i) any reduction or compromise of the
principal loan amount of any Note held by such Lender, the amount or rate of
interest accrued or accruing thereon or the fees due hereunder; and (ii)
extension of the date of any scheduled payment under such Note; and unanimous
consent of all the Revolving Lenders shall be required for (iii) permitting the
sale of or releasing the security interest of the Revolving Lenders in
Collateral which comprises more than ten percent (10%) of net book value of
fixed assets of the Borrower on a consolidated basis (other than sales or
dispositions permitted by Section 4.2 and releases of Collateral in connection
with such sales and dispositions); and (iv) any amendment of Sections 7.1 or 7.2
hereof. The Revolving Lenders irrevocably authorize the Agent, at its option and
in its discretion, (a) to release any Lien granted to or held by the Agent under
any Operative Document (i) upon termination of the Commitments and payment in
full of all Revolving Loans and all other obligations of the Borrower hereunder
and the expiration or termination of all Letters of Credit; (ii) constituting
property sold or to be sold or disposed of as part of or in connection with any
disposition permitted hereunder; or (iii) if approved, authorized or ratified in
writing by the Requisite Revolving Lenders, or all Revolving Lenders if required
by clause (iii) of the immediately preceding sentence; or (b) to subordinate its
interest in any collateral to any holder of a Lien on such collateral that is
permitted by clause (viii) or (xi) of the definition of "Permitted Liens". Upon
request by the Agent at any time, the Revolving Lenders will confirm in writing
the Agent's authority to release, or subordinate its interest in, particular
types or items of collateral pursuant to this Section 7.1. A Revolving Lender's
commitment hereunder may not be increased without the consent of such Revolving
Lender, it being understood, however, that increases in the total revolving
credit facility hereunder may be made with the consent of the Requisite
Revolving Lenders, so long as such increase does not result in the increase of
any non-consenting Revolving Lender's commitment hereunder.

         7.2      Application of Payments. At all times other than when an Event
of Default has occurred and is continuing, payments or prepayments made by the
Borrower may be applied to the indebtedness designated by the Borrower or
otherwise applied as follows:

                  (a) first, to pay interest to date on the Notes and fees due
         to the Revolving Lenders;

                  (b) second, pro rata to the Revolving Lenders, such pro rata
         share to be determined as set forth below in subsection (bb) of this
         Section 7.2.

After the occurrence and during the continuance of an Event of Default, payments
or prepayments on the Notes received by FNB-O or any of the Revolving Lenders
and funds realized upon the disposition of any of the Collateral shall be
applied as follows:

                  (aa) first, to reimburse FNB-O for any reasonable and
         documented costs, expenses, and disbursements (including reasonable and
         documented attorneys' fees) which may be incurred or made by FNB-O: (i)
         in connection with its servicing

                                     - 30 -

<PAGE>

         obligations; (ii) in the process of collecting such payments or funds;
         or (iii) as advances made by FNB-O to protect the Collateral (provided,
         however, that FNB-O shall have no obligation to make such protective
         advances); and

                  (bb) second, pari passu among the Revolving Lenders, based on
         their respective pro rata shares of the funds to be applied. Each
         Revolving Lender's pro rata share shall be equal to a fraction, (x) the
         numerator of which shall be the total principal loan amount then
         outstanding which is owing to each such Revolving Lender under its
         Notes, and (y) the denominator of which shall be the total Principal
         Loan Amount then outstanding which is owing to the Revolving Lenders
         under all Notes.

Except as specifically provided in this Section 7.2, FNB-O shall have no
obligation to repay or prepay any amount due from the Borrower to any of the
other Revolving Lenders nor shall FNB-O have any obligation to purchase all or a
part of any Note hereunder or any Advance made by any Revolving Lenders, nor
shall the Revolving Lenders have any recourse whatsoever against FNB-O with
respect to any failure of the Borrower to repay the indebtedness referenced
herein.

         7.3      Liability of FNB-O. FNB-O shall not be liable to the Revolving
Lenders for any error of judgment or for any action taken or omitted to be taken
by it hereunder, except for gross negligence or willful misconduct. Without
limiting the generality of the foregoing, FNB-O, except as expressly set forth
herein, (a) may consult with legal counsel, independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (b) makes no representation or warranty with
respect to, and shall not be responsible for, the accuracy, completeness,
execution, legality, validity, legal effect or enforceability of this Agreement,
the Notes, or the other Operative Documents, or the value or sufficiency of any
Collateral given by the Borrower or any Guarantor or the priority of the
Revolving Lenders' security interest therein or the financial condition of the
Borrower or any Guarantor; and (c) shall not be responsible for the performance
or observance of any of the terms, covenants or conditions of the Operative
Documents on the part of the Borrower or of any Guarantor and shall not have any
duty to inspect the property (including, without limitation, the books and
records) of the Borrower or of any Guarantor.

         7.4      Transfers. No Revolving Lender shall subdivide or transfer its
respective Notes (except to a Federal Reserve Bank) without first giving ten
(10) days prior written notice to and obtaining the prior written consent (which
consent shall not be unreasonably withheld) of FNB-O and the Borrower. No
Revolving Lender may grant a participation in any Advance hereunder without the
prior written consent of FNB-O (which consent shall not be unreasonably
withheld).

         7.5      Reliance. The Revolving Lenders acknowledge that they have
been advised that none of the Notes nor any interest therein or related thereto
has been (i) registered under the Securities Act of 1933, as amended, nor (ii)
insured by the Federal Deposit Insurance Corporation. The Revolving Lenders
acknowledge that they have received from the Borrower all financial information
and other data relevant to their decision to extend credit to the Borrower and
that they have independently approved the credit quality of the Borrower.

                                     - 31 -

<PAGE>

         7.6      Relationship of Lenders. The Revolving Lenders intend for the
relationships created by this Agreement to be construed as concurrent direct
loans from each Revolving Lender respectively to the Borrower. Nothing herein
shall be construed as a loan from any Revolving Lender to FNB-O or as creating a
partnership or joint venture relationship among them.

         7.7      New Revolving Lenders. In the event that new Revolving Lenders
are added to this Agreement, such Revolving Lenders shall be required to agree
to the inter-creditor provisions of this Article VII.

         7.8      Agenting Fee. The Borrower will pay to FNB-O a quarterly
agenting fee equal to $2,500.00, payable quarterly on or before the last day of
such quarter.

                      VIII. REIMBURSEMENTS; INDEMNIFICATION

         8.1      Capital Adequacy. If, after the date hereof, the adoption or
implementation of any applicable law, rule or regulation regarding capital
adequacy (including, without limitation, any law, rule or regulation
implementing the Basle Accord), or any change therein, or any change in the
interpretation or administration thereof by any central bank or other
governmental authority charged with the interpretation or administration
thereof, or compliance by a Revolving Lender (or its parent) with any guideline,
request or directive regarding capital adequacy (whether or not having the force
of law) of any such central bank or other governmental authority (including,
without limitation, any guideline or other requirement implementing the Basle
Accord), has or would have the effect of reducing the rate of return on such
Revolving Lender's capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which such Revolving
Lender could have achieved but for such adoption, implementation, change or
compliance (taking into consideration such Revolving Lender's policies with
respect to capital adequacy) by an amount deemed by such Revolving Lender to be
material, then such Revolving Lender shall provide to the Borrower notice of
such matter, and from time to time thereafter within ten (10) Business Days
after demand by such Revolving Lender (which demand shall be accompanied by a
statement setting forth the basis for such demand and a calculation of the
amount thereof in reasonable detail), the Borrower shall pay to such Revolving
Lender such additional amount or amounts as will compensate such Revolving
Lender for such reduction which is incurred by such Revolving Lender after the
date of such Revolving Lender's notice to the Borrower under this Section 8.1.
Notwithstanding the preceding sentence, upon Borrower's receipt of such notice
from such Revolving Lender, Borrower may provide to such Revolving Lender its
notice of prepayment in accordance with Section 2.5 hereof. A certificate of
such Revolving Lender claiming compensation under this Section and setting forth
the additional amount or amounts to be paid to it hereunder shall be prima facie
evidence thereof, provided that the determination thereof is made on a
reasonable basis. In determining such amount or amounts, such Revolving Lender
may use any reasonable averaging and attribution methods. Upon receipt of a
notice from a Revolving Lender under this section, the Borrower, upon ten (10)
days prior written notice to the Agent, may replace such Revolving Lender with a
new Revolving Lender that would not require a payment under this section, which
replacement Revolving Lender shall purchase the rights and assume the


                                       32

<PAGE>

obligations of the replaced Revolving Lender under this Agreement and the other
Operative Documents for a price equal to the outstanding principal and accrued
but unpaid interest on the Note issued to such replaced Revolving Lender, plus
the amount of other fees (including without limitation the commitment fee
payable in accordance with Section 2.2 (a) of this Agreement), such fees to be
pro rated through the purchase and assumption date; provided, however, that such
replacement Revolving Lender must be reasonably acceptable to the Agent.

         Each Revolving Lender shall promptly notify the Borrower and the Agent
of any event of which it has knowledge which will result in, and will use
reasonable commercial efforts available to it (and not, in such Revolving
Lender's reasonable judgment, otherwise disadvantageous to such Revolving
Lender) to mitigate or avoid, any obligation by the Borrower to pay any amount
pursuant to this Section 8.1 (and, if any Revolving Lender has given notice of
any such event and thereafter such event ceases to exist, such Revolving Lender
shall promptly so notify the Borrower and the Agent). Without limiting the
foregoing, each Revolving Lender will designate a different funding office if
such designation will avoid (or reduce the cost to the Borrower of) any event
described in the preceding sentence and such designation will not, in such
Revolving Lender's reasonable judgment, be otherwise disadvantageous to such
Revolving Lender.

         8.2      General Indemnity. The Borrower shall indemnify each Revolving
Lender and its directors, officers, employees and agents from and against any
and all losses, claims, liabilities, damages, reasonable and documented
attorneys' fees and disbursements, and other reasonable and documented costs and
expenses which the indemnified party may at any time sustain or incur in
connection with the Borrower's use of loan proceeds; provided that the
indemnified party shall not have any right to be indemnified for its own gross
negligence or willful misconduct. All indemnities and all provisions relative to
reimbursement to the Revolving Lenders of amounts sufficient to compensate the
Revolving Lenders for changes in capital adequacy requirements, including, but
not limited to, Section 8.1 hereof, shall survive the termination of this
Agreement and the payment of the Notes.

                                IX. MISCELLANEOUS

         9.1      Entire Agreement. This Agreement constitutes the entire
