SECTION
3. The Guaranty.

(a)
Each of the Guarantors hereby, subject to the provisions of Section 4(g),
jointly and severally, absolutely, unconditionally, irrevocably, completely and
immediately, as primary obligor and not merely as surety, guarantees to CoBank
the prompt and complete payment and performance when due (whether at stated
maturity, as a mandatory prepayment, by acceleration or otherwise) of the

Guaranty
Loan Nos. RX0583 and RX0584

Documents,
without any demand or notice whatsoever, and that in the case of any extension
of time of payment or renewal of any of the Obligations, the same will be promptly
paid in full when due (whether at stated maturity, as a mandatory prepayment,

Guaranty, or in attempting to protect or preserve any property, personal or
real, securing the Obligations or pledged under any Loan Document;

(c)
Each Guarantor hereby, jointly and severally, guarantees any sum or sums which
become due and owing to CoBank as a result of any order of a bankruptcy court
which requires CoBank to turn over moneys paid by any Borrower, any Guarantor
or any other person to CoBank on account of the Obligations. Each Guarantor
agrees that this Guaranty shall continue to be effective or be reinstated, as
the case may be, if at any time any payment by any Borrower, any Guarantor or
any other person to CoBank on account of the Obligations is rescinded or must
otherwise be returned or restored upon the insolvency or bankruptcy of any
Borrower, any Guarantor, or any other person, all as though such payment had
not been made; and

(d)
Notwithstanding any provision to the contrary contained herein or in any other
Loan Document, the maximum liability of any Guarantor hereunder and under the
other Loan Documents shall in no event exceed the aggregate amount that would
render the guaranty of such Guarantor subject to avoidance under any applicable
law.

SECTION
4. The Guaranty Unconditional.

(a)
Each Guarantor hereby agrees that this is a guaranty of payment and performance
and not of collection only. The liability of each Guarantor under this Guaranty
shall be absolute, unconditional, direct, complete and immediate and shall not
be contingent upon the pursuit of any remedies against any Borrower, any
Guarantor or any other person, nor against any security or lien available to
CoBank, its successors, successors-in-title, endorsees or assigns. Each
Guarantor waives any right to require that an action be brought against any
Borrower, any Guarantor or any other person or to require that resort be had to
any security. In the occurrence of a breach, default, or event of default under
any of the Loan Documents, CoBank shall have the right to enforce its rights,
powers and remedies under any of the Loan Documents, in any order, and all
rights, powers and remedies available to CoBank in such event

4

---

Continuing
Guaranty
Loan Nos. RX0583 and RX0584

shall be
nonexclusive and cumulative of all other rights, powers and remedies provided
thereunder or hereunder or by law or in equity. Accordingly, each Guarantor
hereby authorizes and empowers CoBank upon acceleration of the maturity of any
of the Notes or any other Obligation, at its sole discretion, and without
notice to such Guarantor, to exercise any right or remedy which CoBank may have
or any right or remedy hereinafter granted which CoBank may have as to any
security. Each Guarantor expressly waives any right to require any action on
the part of CoBank to proceed to collect amounts due under any Loan Document;

(b)
Each Guarantor assents to all terms and agreements heretofore or hereafter made
by any Borrower, any of their respective Subsidiaries, any Guarantor, or any
other guarantor of the Obligations with CoBank;

(c)
Each Guarantor hereby consents to the following and agrees that its liability
will not be affected or impaired by (i) the exchange, release or surrender of
any collateral to any Borrower, any Guarantor or any other person, or the
waiver, release or subordination of any security interest, in whole or in part;
(ii) the waiver or delay in the exercise of any of CoBanks rights or remedies
against any Borrower, any Guarantor or any other person; (iii) the release of any Borrower or any other person; (iv)
the renewal, extension or modification of the terms of any of the Obligations
or any instrument or agreement evidencing the same, including, without
limitation, an increase in the principal amount of any of the Notes; and (v)
the acceptance by CoBank of other guaranties;

(d)
Each Guarantor irrevocably waives acceptance hereof, notice of acceptance
hereof, and notice of acceleration of and intention to accelerate the
Obligations, and waives the benefit of any statutes of limitations,
presentment, demand or action on delinquency, protest, notice of dishonor,
notice of default, notice of nonpayment or protest in relation to any
instrument evidencing any of the Obligations, and, to the fullest extent
permitted by law, any other demands or notices required by law;

(e)
Each Guarantor hereby authorizes CoBank, without notice to such Guarantor, to
apply all payments and credits received from any Borrower, from any Guarantor,
or from any other person or realized from any security in such manner and in
such priority as CoBank in its sole judgment shall see fit to the Obligations
which are the subject of this Guaranty;

(f)
The liability of each Guarantor under this Guaranty shall not in any manner be
affected by reason of any action taken or not taken by CoBank, which action or
inaction is consented and agreed to by such Guarantor, nor by the partial or
complete unenforceability or invalidity of any other guaranty or surety
agreement, pledge, assignment, or other security for any of the Obligations. No
delay in making demand on any Guarantor for satisfaction of its liability
hereunder shall prejudice CoBanks right to enforce such satisfaction. All of
CoBanks

5

---

Continuing
Guaranty
Loan Nos. RX0583 and RX0584

rights and
remedies shall be cumulative and any failure of CoBank to exercise any right
hereunder shall not be construed as a waiver of the right to exercise the same
or any other right at any time, and from time to time, thereafter;

(g)
This Guaranty shall be a continuing one and shall be binding upon each
Guarantor regardless of how long before or after the date hereof the
Obligations are incurred until this Guaranty is terminated as provided in this
Guaranty, or until, to the extent provided by applicable law to the extent it
cannot be waived, is revoked by a Guarantor prospectively as to future
transactions, by written notice actually received by CoBank, and such
revocation shall not be effective as to any indebtedness existing or committed
for under the Loan Agreements or the other Loan Documents at the time of actual
receipt of such notice by CoBank, or as to any renewals, extensions or
refinancings thereof. Accordingly, so long as this Guaranty is not revoked
prospectively in accordance with this Subsection 4(g), CoBank may rely
conclusively on a continuing warranty, hereby made, that each Guarantor
continues to be benefited by this Guaranty and CoBank shall have no duty to
inquire into or confirm that the receipt of any such benefits, and this
Guaranty shall be effective and enforceable by CoBank without regard to the
receipt, nature or value of any such benefits;

(h)
Each Guarantor hereby subordinates any and all indebtedness of any Borrower,
any of their respective Subsidiaries, or an other Guarantor now or hereafter
owed to such Guarantor to all Obligations of any Borrower and their respective
Subsidiaries to CoBank, and agrees with CoBank that, from and after the
occurrence of a breach, default or event of default under any of the Loan
Documents and for so long as such breach, default or event of default exists,
such Guarantor shall not demand or accept any payment of principal or interest
from any Borrower, any of its respective Subsidiaries, or any other Guarantor,
shall not claim any offset or other reduction of such Guarantors liability
hereunder because of any such indebtedness and shall not take any action to
obtain any of the security for the Obligations; provided, however,
that, if CoBank so requests, and so long as such breach, default or event of
default exists, such indebtedness shall be collected, enforced and received by
such Guarantor as trustee for CoBank and be paid over to CoBank on account of
the Obligations of any Borrower, its Subsidiaries, or any Guarantor to CoBank,
but without reducing or affecting in any manner the liability of such Guarantor
under the other provisions of this Guaranty; and

(i)
Until the Obligations are paid finally and in full, or this Guaranty is
released as provided herein, each Guarantor hereby irrevocably waives any and
all rights it may have to enforce any of CoBanks rights or remedies or
participate in any security now or hereafter held by CoBank, and any and all
such other rights of subrogation, reimbursement, contribution or
indemnification against any Borrower, any Guarantor or any other person having
any manner of liability for any Borrowers obligations to CoBank, whether or
not arising hereunder, by agreement, at law or in equity.

of any Guarantor to CoBank, and each Guarantor shall remain liable to CoBank up

SECTION 8. Covenants. Each Guarantor covenants and
agrees
with CoBank that so long as this Guaranty remains in effect or the Obligations
have not been fully paid or otherwise satisfied, such Guarantor will take, or

or not taken so that no violation of any provision, covenant or agreement

Loan Nos. RX0583 and RX0584

be construed as a
waiver or a relinquishment for the future of such right or option, but the same
shall continue and remain in full force and effect. The continued performance
by any party of this Guaranty with knowledge of the breach of any term or
condition hereof shall not be deemed a waiver of such breach, and no waiver by

Guarantors with respect to the matters contained herein and may not be
contradicted by evidence of prior or contemporaneous agreements, or subsequent
oral agreements, between the Guarantor and CoBank.
