                             II. REVOLVING FACILITY

     2.1  REVOLVING CREDIT. Until August 31, 2003, FNBO agrees to advance funds
for general corporate purposes to the Borrower on a revolving credit basis up to
the amount of the Commitment in effect from time to time (the "Base Revolving
Credit Facility"); PROVIDED, HOWEVER, that the aggregate amount of funds
available for Advance to the Borrower hereunder shall not exceed the
Availability.

     The Borrower shall not be entitled to any further Advances hereunder after
the occurrence and during the continuation of any Event of Default or Potential
Event of Default, 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 2:00 p.m.
Omaha time on the Business Day prior to the requested date of the Advance. The
Borrower's

                                     - 10 -
<Page>

obligation to make payments of principal and interest on the foregoing revolving
credit indebtedness shall be further evidenced by the Note.

     2.2  REVOLVING CREDIT FEES.

          (a)  The Borrower shall pay to FNBO a commitment fee equal to 3/8 of
     1% (.00375) 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 March 31st, 2003 shall accrue from March
     10, 2003.

          (b)  The Borrower shall also pay an origination fee to FNBO equal to
     $10,000.00, such fee 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 Prime Rate PLUS one quarter of one percent
(.25%). Each change in the Prime Rate shall be effective as of the opening of
business on the day such change in the Prime Rate occurs. The parties hereto
acknowledge that the rate announced publicly by FNBO as its Prime Rate is an
index or base rate and shall not necessarily be its lowest or best rate charged
to its customers or other banks. All interest under the Note 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. The aggregate principal balance outstanding under the Note
together with all accrued but unpaid interest thereon shall be due on the
Termination Date. All obligations of the Borrower under the Note 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 FNBO in
Omaha, Nebraska or at such other address as may be designated by FNBO 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 Note if the Borrower has
given FNBO 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. No
such prepayment shall reduce the Base Revolving Credit Facility.

                                     - 11 -

     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 Note, shall be secured by a
first security interest in the Collateral, as more specifically described in the
Security Agreement and the Pledge Agreement, subject to liens permitted
thereunder. All references in the Security Agreement and the Pledge Agreement to
the "Revolving Credit Agreement" shall mean this Agreement as amended from time
to time.

     2.7  PAYMENT RECEIPT. Payments received before 2:00 p.m. Omaha time on any
Business Day will be credited the same Business Day. Payments received after
2:00 p.m. Omaha time 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 duly organized, validly existing and in good standing under the laws
of the state of its incorporation 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 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. Except as disclosed on Exhibit H attached hereto, 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

                                     - 12 -
<Page>

as a whole; nor is the Borrower or any Subsidiary 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 obligations under its
Operative Documents or a Subsidiary's ability to pay dividends to the Borrower.

     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.

     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.

     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's 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.

     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 E
attached hereto. The Borrower is a Delaware

                                     - 13 -
<Page>

corporation with its principal place of business, chief executive office and the
principal place where it keeps its records concerning the Collateral at 4350
McKinley Street, Omaha, Nebraska 68112.

     3.11 PENSION BENEFITS. Neither the Borrower nor any Subsidiary maintains an
employee benefits pension plan as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (a "Plan"), 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 the most recent financial statement which
has been provided to FNBO 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.

     3.14 ENVIRONMENTAL AND SAFETY AND HEALTH MATTERS. Except as disclosed on
Exhibit F attached hereto:

          (a)  to the best of our knowledge, the operations of the Borrower and
     each Subsidiary comply with (i) all applicable Environmental Laws and (ii)
     all applicable Occupational Safety and Health Laws;

     disposal, or release into the environment of, or treatment, storage or
     disposal of, any Hazardous Substance or any other hazardous, toxic or
     dangerous waste, substance or constituent or other substance, or (ii) any
     unsafe or unhealthful condition at any premises of the Borrower or any
     Subsidiary;

          (d)  neither the Borrower nor any Subsidiary has filed any notice
     under any Environmental Law or Occupational Safety and Health Law
     indicating or reporting (i) any past or present spillage, disposal, or
     release into the environment of, or treatment, storage or disposal of, any
     Hazardous Substance or any other hazardous, toxic or

                                     - 14 -
<Page>

     dangerous waste, substance or constituent or other substance, or (ii) any
     unsafe or unhealthful condition at any premises of the Borrower or any
     Subsidiary; and

          (e)  neither the Borrower nor any Subsidiary has any known contingent
     liability in connection with (i) any past or present spillage, disposal, or

                                  IV. COVENANTS

     The Borrower hereby covenants that:

          (a)  Within thirty (30) days after the end of each month, the
     Borrower, at its sole expense, shall furnish FNBO 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 completed and
     correct, subject to normal changes resulting from year-end audit
     adjustments, by the chief financial officer of the Borrower.

          (b)  Within one hundred and twenty (120) days after the close of the
     Borrower's fiscal year, the Borrower, at its sole expense, shall furnish

     Exchange Commission during the term of this Agreement; (ii) a consolidated
     balance sheet, a statement of earnings of the Borrower and its consolidated

     Potential Event of Default under this Agreement; or (2) have discovered
     such condition or event, as specifically set forth in such certificate,
     which constitutes an Event of Default or a Potential Event of Default under
     such sections. The auditors shall not be liable to FNBO 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 forty-five (45) days after submission to the Securities
     and Exchange Commission, the Borrower shall provide to FNBO copies of its

          reviewed or caused to be reviewed all of the terms of the Operative

          which constitutes an Event of Default or a Potential Event of Default

          Potential Event of Default, under the aforesaid instrument or

     merge or consolidate with any other corporation or entity without the prior
     written consent of FNBO.

          (b)  The Borrower shall not, and shall not permit any Guarantor to,
