day in the next calendar month or the month that is 2,3, or 6 months
thereafter, as the case may be: provided, however, that: (i) in the event such

expiring after the maturity date of the loans. All elections provided for
herein shall be made electronically (if applicable), telephonically or in
writing and must be received by CoBank not later than 12:00 Noon Companys
local time in order to be considered to have been received on that day;
provided, however, that in the case of LIBOR rate loans, all such elections
must be confirmed in writing upon CoBanks request. Interest shall be
calculated on the actual number of days each loan is outstanding on the basis
of a year consisting of 360 days and shall be payable monthly in arrears by the
20th day of the following month or on such other day in such month as CoBank
shall require in a written notice to the Company; provided, however, in the
event the Company elects to fix all or a portion of the indebtedness
outstanding under the LIBOR interest rate option above, at CoBanks option upon
written notice to the Company, interest shall be payable at the maturity of the
Interest Period and if the LIBOR interest rate fix is for a period longer than
three months, interest on that portion of the indebtedness outstanding shall be
payable quarterly in arrears on each three-month anniversary of the
commencement date of such Interest Period, and at maturity.

|Level 3            | Greater than .45 to 1             | 2.15%        

*The Pricing Leverage
Ratio (for determining LIBOR Spread as indicated in subsection (D) above and
the Commitment Fee as indicated in Section 6(A) below) is defined as: (long
term debt + capital leases) divided by (long term debt + capital leases +
Equity + Minority Interests (as defined in the Companys financial
statements)), all as determined in accordance with GAAP consistently applied.

The applicable interest
rate adjustment shall: (i) be considered as of each fiscal quarter end based on

prospective basis only and shall not affect existing fixed rate pricing.

The Company shall select
the applicable rate option at the time it requests a loan hereunder and may,
subject to the limitations set forth above, elect to convert balances bearing
interest at the variable rate option to one of the fixed rate options. Upon the
expiration of any fixed rate period, interest shall automatically accrue at the
variable rate option unless the amount fixed is repaid or fixed for an
additional period in accordance with the terms hereof. Notwithstanding the
foregoing, rates may not be fixed in such a manner as to cause the Company to
have to break any fixed rate balance in order to pay any installment of
principal. All elections provided for herein shall be made electronically (if
applicable), telephonically or in writing and must be received by CoBank not
later than 12:00 Noon Companys local time in order to be considered to have

LIBOR
rate loans, all such elections must be confirmed in writing upon CoBanks
request. Interest shall be calculated on the actual number of days each loan is
outstanding on the basis of a year consisting of 360 days and shall be payable
monthly in arrears by the 20th day of the following month or on such other day
in such month as CoBank shall require in a written notice to the Company;
provided, however, in the event the Company elects to fix all or a portion of
the indebtedness outstanding under the LIBOR interest rate option above, at
CoBanks option upon written notice to the Company, interest shall be payable
at the maturity of the Interest Period and if the LIBOR interest rate fix is
for a period longer than three months, interest on that portion of the
indebtedness outstanding shall be payable quarterly in arrears on each
three-month anniversary of the commencement date of such Interest Period, and
at maturity.

SECTION 4. Promissory Note. The Company promises to repay the loan as follows:
(1) in 30 equal, consecutive quarterly installments of $831,924.36, with the
first such installment due on February 20, 2009, and the last such installment
due on May 20, 2016, and (2) followed by a final installment in an amount equal to
the remaining unpaid principal balance of the loans on August 20, 2016. If any
installment due date is not a day on which CoBank is open for business, then
such installment shall be due and payable on the next day on which CoBank is
open for business. In addition to the above, the Company promises to pay
interest on the unpaid principal balance of the loan at the rate and at the
times set forth above. This note replaces and supersedes, but does not
constitute payment of the indebtedness evidenced by, the promissory note set
forth in the Supplement being amended and restated hereby.

SECTION 5. Prepayment. Subject to the broken funding surcharge provision of the
MLA, the Company may on one Business Days prior written notice prepay all or
any portion of the loan(s). Unless otherwise agreed by CoBank, all prepayments
will be applied to principal installments in the inverse order of their
maturity and to such balances, fixed or variable, as CoBank shall specify.

SECTION 6. Security. The Companys obligations
hereunder and, to the extent related hereto, the MLA, shall be secured as
provided in the Security Section of the MLA, including without limitation as a
future advance under any existing mortgage or deed of trust.

be executed by their duly authorized officers as of the date shown above.
