DEFINITIONS: As used on page 1, " " means the terms that apply to this loan.
"I," "me" or "my" means each Borrower who signs this note and each other person
or legal entity (including guarantors, endorsers, and sureties) who agrees to
pay this note (together referred to as "us"). "You" or "your" means the Lender
and its successors and assigns.
APPLICABLE LAW: The law of the state of Iowa will govern this note. Any term of
this note which is contrary to applicable law will not be effective, unless the
law permits you and me to agree to such a variation. If any provision of this
agreement cannot be enforced according to its terms, this fact will not affect
the enforceability of the remainder of this agreement. No modification of this
agreement may be made without your express written consent. Time is of the
essence in this agreement.
COMMISSIONS OR OTHER REMUNERATION: I understand and agree that any insurance
premiums paid to insurance companies as part of this note will involve money
retained by you or paid back to you as commissions or other remuneration.
In addition, I understand and agree that some other payments to third parties as
part of this note may also involve money retained by you or paid back to you as
commissions or other remuneration.
PAYMENTS: Each payment I make on this note will first reduce the amount I owe
you for charges which are neither interest nor principal. The remainder of each
payment will then reduce accrued unpaid interest, and then unpaid principal. If
you and I agree to a different application of payments, we will describe our
agreement on this note. I may prepay a part of, or the entire balance of this
loan without penalty, unless we specify to the contrary on this note. Any
partial prepayment will not excuse or reduce any later scheduled payment until
this note is paid in full (unless, when I make the prepayment, you and I agree
in writing to the contrary).
INTEREST: Interest accrues on the principal remaining unpaid from time to time,
until paid in full. If I receive the principal in more than one advance, each
advance will start to earn interest only when I receive the advance. The
interest rate in effect on this note at any given time will apply to the entire
principal advanced at that time. You and I may provide in this agreement for
accrued interest not paid when due to be added to principal. Notwithstanding
anything to the contrary, I do not agree to pay and you do not intend to charge
any rate of interest that is higher than the maximum rate of interest you could
charge under applicable law for the extension of credit that is agreed to here
(either before or after maturity). If any notice of interest accrual is sent and
is in error, we mutually agree to correct it, and if you actually collect more
interest than allowed by law and this agreement, you agree to refund it to me.
INDEX RATE: The index will serve only as a device for setting the rate on this
note. You do not guarantee by selecting this index, or the margin, that the rate
on this note will be the same rate you charge on any other loans or class of
loans to me or other borrowers,
ACCRUAL METHOD: The amount of interest that I will pay on this loan will be
calculated using the interest rate and accrual method stated on page 1 of this
note. For the purpose of interest calculation, the accrual method will determine
the number of days in a "year." If no accrual method is stated, then you may use
any reasonable accrual method for calculating interest.
POST MATURITY RATE: For purposes of deciding when the "Post Maturity Rate"
(shown on page 1) applies, the term "maturity" means the date of the last
scheduled payment indicated on page 1 of this note or the date you accelerate
payment on the note, whichever is earlier.
SINGLE ADVANCE LOANS: If this is a single advance loan, you and I expect that
you will make only one advance of principal. However, you may add other amounts
to the principal if you make any payments described in the "PAYMENTS BY LENDER"
paragraph below, or if we have agreed that accrued interest not paid when due
may be added to principal.
MULTIPLE ADVANCE LOANS: If this is a multiple advance loan, you and I expect
that you will make more than one advance of principal. If this is closed end
credit, repaying a part of the principal will not entitle me to additional
credit,
PAYMENTS BY LENDER: If you are authorized to pay, on my behalf, charges I am
obligated to pay (such as property insurance premiums), then you may treat those
payments as advances and add them to the unpaid principal under this note, or
you may demand immediate payment of the charges.
REAL ESTATE OR RESIDENCE SECURITY: If this note is secured by real estate or a
residence that is personal property, the existence of a default and your
remedies for such a default will be determined by applicable law, by
the    terms of any separate instrument creating the security interest and, to
the extent not prohibited by law and not contrary to the terms of the separate
security instrument, by the "Default" and "Remedies" paragraphs herein.
DEFAULT: I will be in default if any one or more of the following occur: (1) I
fail to make a payment on time or in the amount due; (2) I fail to keep the
property insured, if required; (3) I fail to pay, or keep any promise, on any
debt or agreement I have with you; (4) any other creditor of mine attempts to
collect any debt I owe him through court proceedings; (5) I die, am declared
incompetent, make an assignment for the benefit of creditors,

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

or become insolvent (either because my liabilities exceed my assets or I am
unable to pay my debts as they become due); (6) I make any written statement or
provide any financial information that is untrue or inaccurate at the time it
was provided; (7) I do or fail to do something which causes you to believe that
you will have difficulty collecting the amount I owe you; (8) any collateral
securing this note is used in a manner or for a purpose which threatens
confiscation by a legal authority; (9) I change my name or assume an additional
name without first notifying you before making such a change; (10) I fail to
plant, cultivate and harvest crops in due season; (11) any loan proceeds are
used for a purpose that will contribute to excessive erosion of highly erodible
land or to the conversion ,of wetlands to produce an agricultural commodity, as
further explained in 7 C.F.R. Part 1940, Subpart G, Exhibit M.
REMEDIES: Except as provided in the next paragraph, if this note is secured by
agricultural land (as defined in Iowa Code § 172C.1) and I am in default on this
note, you will give me notice of my right to cure. You may exercise your
remedies only if I fail to cure my default within 45 days after you mail the
notice (or 45 days after actual delivery if you use a means other than certified
mail).
A notice of right to cure is not necessary and you may immediately exercise your
remedies if you have: a) given me the notice with respect to two prior defaults,
b) you have given me the notice with respect to a default occurring within 12
months before the current default, or I voluntarily surrender the agricultural
land and you accept it in full satisfaction of the debt.
Subject to the above limitations and any limitations imposed by Iowa Code
Chapter 654A, if I am in default on this note you have, but are not limited to,
the following remedies:
(1) You may demand immediate payment of all I owe you under this note
(principal, accrued unpaid interest and other accrued charges).
(2) You may set off this debt against any right I have to the payment of money
from you, subject to the terms of the "set-off" paragraph herein.
(3) You may demand security, additional security, or additional parties to be
obligated to pay this note as a condition for not using any other remedy.
(4) You may refuse to make advances to me or allow purchases on credit by me.
(5) You may use any remedy you have under state or federal law.
By selecting any one or more of these remedies you do not give up your right to
later use any other remedy. By waiving your right to declare an event to be a
default, you do not waive your right to later consider the event as a default if
it continues or happens again.
COLLECTION COSTS AND ATTORNEY'S FEES: I agree to pay all costs of collection,
replevin or any other or similar type of cost if I am in default. In addition,
if you hire an attorney to collect this note, I also agree to pay any fee you
incur with such attorney plus court costs (except where prohibited by law). To
the extent permitted by the United States Bankruptcy Code, I also agree to pay
the reasonable attorney's fees and costs you incur to collect this debt as
awarded by any court exercising jurisdiction under the Bankruptcy Code.
WAIVER: I give up my rights to require you to do certain things. I will not
require you to:
(1) demand payment of amounts due (presentment);
(2) obtain official certification of nonpayment (protest); or
(3) give notice that amounts due have not been paid (notice of dishonor).
I waive any defenses I have based on suretyship or impairment of collateral.
OBLIGATIONS INDEPENDENT: I understand that I must pay this note even if someone
else has also agreed to pay it (by, for example, signing this form or a separate
guarantee or endorsement). You may sue me alone, or anyone else who is obligated
on this note, or any number of us together, to collect this note. You may, do so
without any notice that it has not been paid (notice of dishonor). You may
without notice release any party to this agreement without releasing any other
party. If you give up any of your rights, with or without notice, it will not
affect my duty to pay this note. Any extension of new credit to any of us, or
renewal of this note by all or less than all of us will not release me from my
duty to pay it. (Of course, you are entitled to only one payment in full.) I
agree that you may at your option extend this note or the debt represented by
this note, or any portion of the note or debt, from time to time without limit
or notice and for any term without affecting my liability for payment of the
note. I will not assign my obligation under this agreement without your prior
written approval.
FINANCIAL INFORMATION: I agree to provide you, upon request, any financial
statement or information you may deem necessary. I warrant that the financial
statements and information I provide to you are or will be accurate, correct and
complete.
NOTICE: Unless otherwise required by law, any notice to me shall be given by
delivering it or by mailing it by first class mail addressed to me at my last
known address. My current address is on page 1. I agree to inform you in writing
of any change in my address. I will give any notice to you by mailing it first
class to your address stated on page 1 of this agreement, or to any other
address that you have designated.
