contemporaneously with each Advance, payable to the order of the Lender, in the
principal amount of the Advance it evidences. Each Note shall be dated as of the
date of the Advance it evidences.

     Records maintained by Lender shall be conclusive evidence, absent manifest
error, of the amount of the Advances made by Lender to Borrower and each
Subsidiary, and the interest and principal payments thereon. Any failure to so
record, or any error in recordation, shall not, however, limit or otherwise
affect the obligation of Borrower or the respective Subsidiary under the Loan
Documents to pay any amount owing pursuant to the respective Obligation.

     All payments of principal, interest, and other amounts required to be paid
by Borrower or a Subsidiary pursuant to this Facility shall be paid to Lender at

Day, and such extension of time shall be included in the computation of interest
and fees, as applicable. Payments made after 12:00 Noon, Omaha, Nebraska time
shall be deemed made on the next Business Day.

     2.2 INTEREST AND PRINCIPAL PAYMENTS.

     Except as otherwise provided herein, interest on all Advances shall accrue

reduced to an interest rate that is less than 4.0% per annum. The interest rate
shall be adjusted daily.

     Interest accrued on each Advance shall be paid to Lender in arrears on the
first Business Day of the month immediately succeeding the month during which
any Advance is made by Lender and on the first day of each and every month
thereafter until such Advance is paid in full.

7

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

 

     Deposit Advances shall be paid in full on the date of closing of the
acquisition of the respective Property or on the date of closing of permanent
financing for a Property, as applicable.

     With respect to Notes evidencing Deposit Advances that are not paid in full
prior to the Termination Date, in the event that Borrower has not replaced this
Facility with a facility provided by a different lender, or in the event that
Lender has not renewed this Facility, Lender will extend the term of the Note
evidencing such Deposit Advance for an additional term, provided, that such
additional term shall, in any and all events, mature not later than six
(6) months subsequent the Termination Date.

     Acquisition Advances shall be paid in full upon the earlier to occur of
(i) closing of the permanent financing for the respective Property, or (ii) six
(6) months from the date on which such Acquisition Advance is made by Lender,
provided, in the event that said 6-month term expires subsequent to the
Termination Date , the maturity date of such Note shall be that date which is
six (6) months subsequent to the date of execution of such Note.

     With respect to Notes evidencing Acquisition Advances that mature
subsequent to the Termination Date, in the event that Borrower has not replaced
this Facility with a facility provided by a different lender, or in the event
that Lender has not renewed this Facility, Lender will extend the term of the
Note evidencing such Acquisition Advance for an additional term not exceeding
364 calendar days from the initial maturity date for such Acquisition Advance
(i) at an interest rate not exceeding one percent (1.0%) greater than the Prime
Rate, (ii) for a term not exceeding 364 calendar days from the initial maturity
date of the Note executed in conjunction with such Acquisition Advance, and
(iii) requiring payment of principal and interest installments amortized over a
term equal to the remaining term of the Property Lease pertaining to the
Property with respect to which such Acquisition Advance was granted, provided,
in the event that such Property Lease includes a provision that permits
termination of such Property Lease on a date (“Early Termination Date”) that
precedes the scheduled maturity date of such Property Lease,

8

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

 

such amortization term shall be reduced to a date that is coterminous with the
Early Termination Date.

     Borrower or a Subsidiary may prepay all or any part of any Advance at any
time upon ten (10) Business Days’ prior written notice to Lender. Each such
notice shall specify the prepayment date and the Advance being prepaid.

     2.3 DEFAULT RATE.

     In the event that any installment is not paid within ten (10) days from the
date on which the same is due and payable, interest shall accrue on the
principal amount of the Note evidencing the respective Advance from the date on
which such installment was due and payable at a rate of interest that is four
percent (4.0%) greater than the Prime Rate (“Default Rate”) until paid.

     2.4 LATE FEE.

     In the event that any installment is not paid within ten (10) days from the
date on which such installment is due and payable pursuant to the respective
Note, Lender may, at its option, assess a late fee in an amount equal to five
percent (5.0%) of the amount of such installment. Such late fee shall be paid
contemporaneously with the payment of the accrued installment, and in the event
that such late fee is not paid contemporaneously with payment of the accrued
installment, interest shall accrue on the late fee at the Default Rate.

     Imposition of a late fee shall not preclude Lender from assessing interest
at the Default Rate as set forth in Section 2.3 hereof.

     2.5 INTEREST CALCULATIONS.

     All payments of interest shall be calculated on the basis of the actual
number of days elapsed (including the first day but excluding the last day)
computed on the basis of a calendar year consisting of 360 days. All interest
rate determinations and calculations by Lender shall be conclusive and binding
absent manifest error.

9

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

 

     2.6 MAXIMUM RATE; USURY.

     All agreements between Lender and Borrower, whether now existing or
hereafter arising and whether written or oral, are expressly limited so that in
no contingency or event whatsoever, whether by reason of advancement of the
proceeds hereof, acceleration of maturity of the unpaid principal balance
hereof, or otherwise, shall the amount paid or agreed to be paid to Lender for
the use, forbearance or detention of the money to be advanced hereunder exceed
the highest lawful rate permissible under applicable usury laws. If, from any
circumstance whatsoever, fulfillment of any provision hereof, or in the Security
Instrument securing any Note, or any other agreement referred to herein, at the
time performance of such provision shall be due, shall involve transcending the
limit of validity prescribed by law which a court of competent jurisdiction may
deem applicable hereto, then, ipso facto, the obligation to be fulfilled shall
be reduced to the limit of such validity, and if from any circumstance the
holder hereof shall ever receive as interest an amount which would exceed the
highest lawful rate, such amount that would be excessive interest shall be
applied to the reduction of the unpaid principal balance due hereunder and not
to the payment of interest, or if such excessive amount exceeds the unpaid
principal balance, such excess shall be refunded to Borrower. All interest paid,
or agreed to be paid to Lender, to the extent permitted by applicable law, shall
be amortized, prorated, allocated and spread throughout the full period until
payment in full of principal and interest of this Facility, including any period
of extension or renewal, so that the interest for such full period shall not
exceed the maximum amount permitted by applicable Law. This provision shall
control every other provision of all agreements between Lender and Borrower.

     2.7 ORDER OF APPLICATION.

     Payments and prepayments of any Note shall be applied in the following
order:

     (i) to the payment of all fees and reasonable expenses for which Lender has
not been paid or reimbursed as required by the Loan Documents;

     (ii) accrued and unpaid late charges;

     (iii) accrued and unpaid interest calculated at the Default Rate;

10

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

 

     (iv) accrued and unpaid interest calculated at Prime Rate; and

     (v) to the payment of the principal indebtedness due and owing pursuant to
any Note in such order as Lender may elect.

     2.8 OFFSET.

     Upon the occurrence and during the continuance of an Event of Default,
Lender shall be entitled to exercise its right of offset against (i) each and
every account and other property, or any interest therein, that Borrower may now
or hereafter have with, or that is now or hereafter in the possession of,
Lender, and (ii) the FNCM Account, to the extent of the full amount of all
Advances owed to Lender.

     2.9 TAXES.

     Any and all payments by Borrower or any Subsidiary to or for the account of
Lender hereunder or under any other Loan Document shall be free and clear of and
without deduction for any and all present or future Taxes or fees, excluding
Taxes imposed on income payable to Lender. If Borrower or any Subsidiary shall
be required by Law to deduct any Taxes from or in respect of any sum payable
under this Facility, (i) the sum payable by Borrower or such Subsidiary shall be

available to Lender pursuant to this Agreement, any Loan Document, the Laws of
the State of Nebraska and any other applicable jurisdiction as Lender shall deem
appropriate.

     9.3 PERFORMANCE BY LENDER.

     If any duty, covenant or agreement imposed upon any Consolidated Company by
the terms and provisions of this Agreement or any Loan Document is not performed
in accordance with the terms and provisions of this Agreement or such Loan
Document, Lender may, at its option, after the occurrence and during the
continuance of an Event of Default, perform or attempt to perform such covenant,
duty, or agreement on behalf of such Consolidated Company. In such event, any
amount expended by Lender in such performance or attempted performance shall be
payable by the Consolidated Companies, jointly and severally, to Lender upon
demand, shall become part of the Obligations, and shall bear interest at the
Default Rate from and after the date of such expenditure by Lender. This
provision shall not, however, be construed to impose any duty upon Lender to
perform any such covenant, duty, or agreement, and Lender shall not have any
liability or responsibility for the performance of any such covenant, duty, or
agreement of any Consolidated Company unless Lender, by express written consent,
assumes such responsibility.

     9.4 COURSE OF DEALING.

     The acceptance by Lender, at any time, or from time to time, of partial
payment of any Obligation shall not constitute a waiver of any Event of Default
or Potential Default then existing.

32

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

 

A waiver by Lender of any Event of Default or Potential Default shall not
constitute a waiver of any other then existing or subsequent Event of Default or
Potential Default. No delay or omission by Lender in exercising any right or
remedy available to Lender pursuant to this Agreement or any Loan Document
shall, in any manner, affect or impair such right or remedy available to Lender
or constitute a waiver thereof or acquiescence therein, and any partial exercise
of any such right or remedy shall not preclude Lender from further exercise
thereof, or the exercise of any other right or remedy available to Lender.

     9.5 CUMULATIVE RIGHTS.

     All rights and remedies available to Lender pursuant to this Agreement and
the Loan Documents are cumulative and in addition to any and all other rights
and remedies available to Lender at law or in equity.

     9.6 APPLICATION OF PROCEEDS.

     Any and all proceeds received by Lender in conjunction with the exercise of
any right or remedy relating to any Obligation shall be applied in the order and
in the manner set forth in Section 2.7 hereof.

     9.7. CERTAIN PROCEEDINGS.

     Borrower will promptly execute and deliver, and will cause the execution
and delivery by a Subsidiary of, all applications, certificates, instruments,
statements, and any and all other documents and agreements as Lender may
reasonably request in connection with obtaining any consent, approval,
registration, qualification, permit, license, or authorization of any Person
that is necessary, or appropriate to effectuate the exercise of any right or
remedy available to Lender pursuant to this Agreement and the Loan Documents.
Borrower agrees that the terms and provisions of this Section 9.7 may be
specifically enforced.

     9.8 EXPENDITURES BY LENDER.

     Borrower or the respective Subsidiary shall pay, within ten (10) Business
Days after request therefor, (a) reasonable costs, fees (including reasonable
attorney fees) and expenses

33

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

 

paid or incurred by Lender in connection with the preparation and administration
of this Agreement and all Loan Documents, and (b) all reasonable costs, fees,
and expenses of Lender in connection with the enforcement of any Obligation
hereunder or the exercise of any right or remedy pursuant to this Agreement or
any Loan Document. Any and all such costs, fees, and expenses shall constitute
Obligations owing hereunder and shall bear interest at the Default Rate from the
date on which the same are due and payable until the date of payment by Borrower
or the respective Subsidiary.

     In the event that any sum required to be paid by Borrower or a Subsidiary
pursuant to this Section 9.8 is not paid within ten (10) days from the date on
which request for payment is made by Lender, Borrower hereby authorizes Lender
to advance such sum(s) to itself from the FNCM Account. In the event that the
balance in the FNCM Account, after deduction of amounts in the FNCM Account that
are subject to Control Agreements, is insufficient to pay such expenditure, the
failure to reimburse Lender for payment of such expenditure shall constitute an
Event of Default hereunder.

Loan Document are, unless otherwise specified, for convenience only and shall

power preclude any other or further exercise thereof or the exercise of any
other right or power hereunder. No modification or waiver of any provision of
this Agreement or of any Loan Document, nor consent to any departure by the
Borrower or a Subsidiary therefrom, shall in any event be effective unless the
same shall be in writing and signed by Lender, and then any such waiver or
consent shall be

34
