Dear George,


Community Bank, Indianola is pleased to commit to Aquapro Corporation two
revolving lines of credit. The first is in the amount of $900,000.00 for the
purpose of financing catfish feed purchased from Delta Western. The second is in
the amount of $800,000.00 to be used for catfish production. This commitment is
contingent on the following terms and conditions:

         1)       The notes will be established as a revolving line of credit
for the specific and expressed purposes of financing catfish feed purchased
from Delta Western to be used to feed Aquapro Corporation and for catfish
production from the $900,000.00 feed line.

         2)       It is understood between Aquapro Corporation, hereinafter
referred to as borrower, and Community Bank, Indianola, hereinafter referred to
as lender, that borrower may not enter into any other catfish operations
involving the production and sale of catfish without prior written consent of
the lender. It is further understood that borrower may not pledge any assets
described in the security agreement between borrower and lender without prior
written consent of the lender.

         3)       The security on the loan will be a perfected first lien
position on all FishCo stock owned. Minimum number of shares pledged will be 448
shares of FishCo. A first lien position on inventory including fingerlings, food
fish, stockers and accounts receivable will also be granted by Aquapro. A first
lien position will also be taken on approximately 553 acres of land located in
Sunflower County and Leflore County known as Circle Creek and Panther Run and a
second lien on 647 acres of land located in Bolivar County. A blanket lien on
all equipment. An assignment of $1,000,000 of life insurance taken on George
Hastings and Randle Willoughby.

         4)       The interest rate charged on the loan will be equal to New
York Consensus Prime plus 165 basis points and will be subject to daily
adjustments.

         5)       This line of credit will mature on March 15, 2001.

         6)       An operating deposit account will be maintained at Community
Bank, Indianola by Aquapro. All proceeds from pledged inventory sales and
account receivable collection will be deposited into the account and 50% will
be applied to the feed line and 50% will be applied to the production line,
first to interest and secondly to principal. Maximum principal balances below
will apply to the feed line and production line respectively.

Noncompliance with the above dates will result in the borrower being required
to obtain other outside funding to be applied to the LOC until the stated
compliance is achieved.

         7)       By acceptance of this commitment letter, the borrower agrees
to comply with all terms and conditions herein and to a 1% ($17,000.00)
commitment fee. Fee payable to Community Bank, Indianola at the time the
commitment letter is accepted and delivered.

         8)       The personal guarantee of George S. Hastings on the line of
credit is required.

         9)       Monthly financial statements will be required to be submitted
to Community Bank, Indianola by the borrower within three weeks after the close
of the accounting period.

        10)       As of today's date, there are outstanding taxes due for 1999
on certain parcels of the real estate taken as collateral by Community Bank.
These taxes must be paid in full and the receipt delivered to the bank as soon
as the correct amount has been determined.

         11)     Approval of funds in the amount of $900,000.00 for the feed
production line and $800,000.00 on the production line are contingent on a
consummated purchase with Federal Land Bank Association to increase the present
water acreage by an additional 525 acres. The consummated sale will be evidenced
by a Warranty Deed transferred on all land and a Bill of Sale transferred on
all equipment, inventory and miscellaneous items. The present loans will be
capped at the level of $700,000.00 on the feed line and $400,000.00 on the
production line until such evidence of a consummated sale is given.


Community Bank, Indianola appreciates the opportunity to provide Aquapro
Corporation with this credit facility and I am looking forward to working with
you during this exciting time.


Sincerely,

COMMUNITY BANK
/s/ JOSEPH J. RICOTTA

                   ADDITIONAL TERMS OF THE SECURITY AGREEMENT

GENERALLY - This agreement secures this note and any other debt I have with
you, now or later. However, it will not secure other debts if you fail with
respect to such other debts, to make any required disclosure about this
security agreement or if you fail to give any required notice of the right of
rescission. If property described in this agreement is located in another
state, this agreement may also, in some circumstances, be governed by the law
of the state in which the Property is located.
OWNERSHIP AND DUTIES TOWARD PROPERTY - I represent that I own all of the
Property, or to the extent this is a purchase money security interest I will
acquire ownership of the Property with the proceeds of the loan. I will defend
it against any other claim. Your claim to the Property is ahead of the claims
of any other creditor. I agree to do whatever you require to protect your
security interest and to keep your claim in the Property ahead of the claims of
other creditors. I will not do anything to harm your position.
         I will keep books, records and accounts about the Property and my
business in general. I will let you examine these records at any reasonable
time. I will prepare any report or accounting you request, which deals with the
Property.
         I will keep the Property in my possession and will keep it in good
repair and use it only for the purpose(s) described on page 1 of this
agreement. I will not change this specified use without your express written
permission. I represent that I am the original owner of the Property and, if I
am not, that I have provided you with a list of prior owners of the Property.
         I will keep the Property at my address listed on page 1 of this
agreement, unless we agree I may keep it at another location. If the Property
is to be used in another state, I will give you a list of those states. I will
not try to sell the Property unless it is inventory or I receive your written
permission to do so. If I sell the Property I will have the payment made
payable to the order of you and me.
         You may demand immediate payment of the debt(s) if the debtor is not a
natural person and without your prior written consent; (1) a beneficial
interest in the debtor is sold or transferred, or (2) there is a change in
either the identity or number of members of a partnership, or (3) there is a
change in ownership of more than 25 percent of the voting stock of a
corporation.
         I will pay all taxes and charges on the Property as they become due.
You have the right of reasonable access in order to inspect the Property. I
will immediately inform you of any loss or damage to the Property.
         If I fail to perform any of my duties under this security agreement,
or any mortgage, deed of trust, lien or other security interest, you may
without notice to me perform the duties or cause them to be performed. Your
right to perform for me shall not create an obligation to perform and your
failure to perform will not preclude you from exercising any of your other
rights under the law or this security agreement.
PURCHASE MONEY SECURITY INTEREST - For the sole purpose of determining the
extent of a purchase money security interest arising under this security
agreement: (a) payments on any nonpurchase money loan also secured by this
agreement will not be deemed to apply to the Purchase Money Loan, and (b)
payments on the Purchase Money Loan will be deemed to apply first to the
nonpurchase money portion of the loan, if any, and then to the purchase money
obligations in the order which the items of collateral were acquired or if
acquired at the same time, in the order selected by you. No security interest
will be terminated by application of this formula. "Purchase Money Loan" means
any loan the proceeds of which, in whole or in part, are used to acquire any
collateral securing the loan and all extensions, renewals, consolidations and
refinancing of such loan.
PAYMENTS BY LENDER - You are authorized to pay, on my behalf, charges I am or
may become obligated to pay to preserve or protect the secured property (such
as property insurance premiums). You may treat those payments as advances and
add them to the unpaid principal under the note secured by this agreement or
you may demand immediate payment of the amount advanced.
INSURANCE - I agree to buy insurance on the Property against the risks and for
the amounts you require and to furnish you continuing proof of coverage. I will
have the insurance company name you as loss payee on any such policy. You may
require added security if you agree that insurance proceeds may be used to
repair or replace the Property. I will buy insurance from a firm licensed to do
business in the state where you are located. The firm will be reasonably
acceptable to you. The insurance will last until the Property is released from
this agreement. If I fail to buy or maintain the insurance (or fail to name you
as loss payee) you may purchase it yourself.
WARRANTIES AND REPRESENTATIONS - If this agreement includes accounts, I will
not settle any account for less than its full value without your written
permission. I will collect all accounts until you tell me otherwise. I will
keep the proceeds from all the accounts and any goods which are returned to me
or which I take back in trust for you. I will not mix them with any other
property of mine. I will deliver them to you at your request. If you ask me to
pay you the full price on any returned items or items retaken by myself, I will
do so.
         If this agreement covers inventory, I will not dispose of it except in
my ordinary course of business at the fair market value for the Property, or at
a minimum price established between you and me.
         If this agreement covers farm products I will provide you, at your
request, a written list of the buyers, commission merchants or selling agents to
or through whom I may sell my farm products. In addition to those parties named
on this written list, I authorize you to notify at your sole discretion any
additional parties regarding your security interest in my farm products. I
remain subject to all applicable penalties for selling my farm products in
violation of my agreement with you and the Food Security Act. In this paragraph
the terms farm products, buyers, commission merchants and selling agents have
the meanings given to them in the Federal Food Security Act of 1985.
REMEDIES - I will be in default on this security agreement if I am in default on
any note this agreement secures or if I fail to keep any promise contained in
the terms of this agreement. If I default, you have all of the rights and
remedies provided in the note and under the Uniform Commercial Code. You may
require me to make the secured property available to you at a place which is
reasonably convenient. You may take possession of the secured property and sell
it as provided by law. The proceeds will be applied first to your expenses and
then to the debt. I agree that 10 days written notice sent to my last known
address by first class mail will be reasonable notice under the Uniform
Commercial Code. My current address is on page 1. I agree to inform you in
writing of any change of my address.
FILING - A carbon, photographic or other reproduction of this security
agreement or the financing statement covering the Property described in this
agreement may be used as a financing statement where allowed by law. Where
permitted by law, you may file a financing statement which does not contain my
signature, covering the Property secured by this agreement.

                                                                   (page 2 of 3)
<PAGE>   6
                          ADDITIONAL TERMS OF THE NOTE

DEFINITIONS - As used on pages 1 and 2, "[X]" 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 in which you are located will govern this
agreement. Any term of this agreement 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.

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 sum outstanding at that time. 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 in this note
(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 interest
rate on this note. You do not guarantee by selecting this index, or the margin,
that the interest rate on this note will be the same rate you charge on any
other loans or class of loans you make to me or other borrowers.

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 on page 2.

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.

SET-OFF - I agree that you may set off any amount due and payable under this
note against any right I have to receive money from you.

         "Right to receive money from you" means:

         (1) any deposit account balance I have with you;
         (2) any money owed to me on an item presented to you or in your
             possession for collection or exchange; and
         (3) any repurchase agreement or other nondeposit obligation.

         "Any amount due and payable under this "note" means the total amount of
which you are entitled to demand payment under the terms of this note at the
time you set off. This total includes any balance the due date for which you
properly accelerate under this note.

         If my right to receive money from you is also owned by someone who has
not agreed to pay this note, your right of set-off will apply to my interest in
the obligation and to any other amounts I could withdraw on my sole request or
endorsement. Your right of set-off does not apply to an account or other
obligation where my rights are only as a representative. It also does not apply
to any Individual Retirement Account or other tax-deferred retirement account.

         You will not be liable for the dishonor of any check when the dishonor
occurs because you set off this debt against any of my accounts. I agree to hold
you harmless from any such claims arising as a result of your exercise of your
right to set-off.

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 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 - 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 unpaid
             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.
         (6) You may make use of any remedy given to you in any agreement
             securing this note.

         By selecting any one or more of these remedies you do not give up your
right to use later any other remedy. By waiving your right to declare an event
to be a default, you do not waive your right to consider later the event 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 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.

CREDIT INFORMATION - I agree and authorize you to obtain credit information
about me from time to time (for example, by requesting a credit report) and to
report to others your credit experience with me (such as a credit reporting
agency). 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.

<PAGE>   9
                             ADDITIONAL PROVISIONS

3. RIGHTS OF SECURED PARTY. Debtor agrees that Secured Party may at any time,
whether before or after the occurrence of an Event of Default and without
notice or demand of any kind, (i) notify the obligor on or issuer of any
Collateral to make payment to Secured Party of any amounts due or distributable
thereon, (ii) in Debtor's name or Secured Party's name enforce collection of
any Collateral by suit or otherwise, or surrender, release or exchange all or
any part of it, or compromise, extend or renew for any period any obligation
evidenced by the Collateral, (iii) receive all proceeds of the Collateral, and
(iv) hold any increase or profits received from the Collateral as additional
security for the Obligations, except that any money received from the
Collateral shall, at Secured Party's option, be applied in reduction of the
Obligations, in such order of application as Secured Party may determine, or be
remitted to Debtor.

4. EVENTS OF DEFAULT. Each of the following occurrences shall constitute an
event of default under this Agreement (herein called "Event of Default"); (i)
Debtor shall fail to pay any or all of the Obligations when due or (if payable
on demand) on demand, or shall fail to observe or perform any covenant or
agreement herein binding on it; (ii) any representation or warranty by Debtor
set forth in this Agreement or made to Secured Party in any financial
statements or reports submitted to Secured Party by or on behalf of Debtor
shall prove materially false or misleading; (iii) a garnishment summons or a
writ of attachment shall be issued against or served upon the Secured Party for
the attachment of any property of the Debtor or any indebtedness owing to
Debtor; (iv) Debtor or any guarantor of any Obligation shall (A) be or become
insolvent (however defined); (B) voluntarily file, or have filed against it
involuntarily, a petition under the United States Bankruptcy Code; or (C) if a
corporation, partnership or organization, be dissolved or liquidated or, if a
partnership, suffer the death of a partner or, if an individual, die; or (D)
go out of business; (v) Secured Party shall in good faith believe that the
value then realizable by collection or disposition of the Collateral, after
deduction of expenses of collection and disposition, is less than the aggregate
unpaid balance of all Obligations then outstanding; (vi) Secured Party shall in
good faith believe that the prospect of due and punctual payment of any or all
of the Obligations is impaired.

5. REMEDIES UPON EVENT OF DEFAULT. Upon the occurrence of an Event of Default
and at any time thereafter, Secured Party may exercise any one or more of the
following rights or remedies: (i) declare all unmatured Obligations to be
immediately due and payable, and the same shall thereupon be immediately due
and payable, without presentment or other notice or demand; (ii) exercise all
voting and other rights as a holder of the Collateral; (iii) exercise and
enforce any or all rights and remedies available upon default to a secured
party under the Uniform Commercial Code, including the right to offer and sell
the Collateral privately to purchasers who will agree to take the Collateral
for investment and not with a view to distribution and who will agree to the
imposition of restrictive legends on the certificates representing the
Collateral, and the right to arrange for a sale which would otherwise qualify
as exempt from registration under the Securities Act of 1933; and if notice to
Debtor of any intended disposition of the Collateral or any other intended
action is required by law in a particular instance, such notice shall be deemed
commercially reasonable if given at least 10 calendar days prior to the date of
intended disposition or other action; (iv) exercise or enforce any or all other
rights or remedies available to Secured Party by law or agreement against the
Collateral, against Debtor or against any other person or property. Upon the
occurrence of the Event of Default described in Section 4 (iv) (B), all
Obligations shall be immediately due and payable without demand or notice
thereof.

6. MISCELLANEOUS. Any disposition of the Collateral in the manner provided in
Section 5 shall be deemed commercially reasonable. This Agreement can be
waived, modified, amended, terminated or discharged, and the Security Interest
can be released, only explicitly in a writing signed by Secured Party. A waiver
signed by Secured Party shall be effective only in the specific instance and
for the specific purpose given. Mere delay or failure to act shall not preclude
the exercise or enforcement of any of Secured Party's rights or remedies. All
rights and remedies of Secured Party shall be cumulative and may be exercised
singularly or concurrently, at Secured Party's option, and the exercise or
enforcement of any one such right or remedy shall neither be a condition to nor
bar the exercise or enforcement of any other. All notices to be given to Debtor
shall be deemed sufficiently given if delivered or mailed by registered or
certified mail, postage prepaid, to Debtor at its address set forth above or at
the most recent address shown on Secured Party's records. Secured Party's duty
of care with respect to Collateral in its possession (as imposed by law) shall
be deemed fulfilled if Secured Party exercises reasonable care in physically
safekeeping such Collateral or, in the case of Collateral in the custody or
possession of a bailee or other third person, exercises reasonable care in the
selection of the bailee or other third person, and Secured Party need not
otherwise preserve, protect, insure or care for any Collateral. Secured Party
shall not be obligated to preserve any rights Debtor may have against prior
parties, to exercise at all or in any particular manner any voting rights which
may be available with respect to any Collateral, to realize on the Collateral
at all or in any particular manner or order, or to apply any cash proceeds of
Collateral in any particular order of application. Debtor will reimburse
Secured Party for all expenses (including reasonable attorney's fees and legal
expenses) incurred by Secured Party in the protection, defense or enforcement
of the Security Interest, including expenses incurred in any litigation or
bankruptcy or insolvency proceedings. This Agreement shall be binding upon and
inure to the benefit of Debtor and Secured Party and their respective heirs,
representatives, successors and assigns and shall take effect when signed by
Debtor and delivered to Secured Party, and Debtor waives notice of Secured
Party's acceptance hereof. This Agreement shall be governed by laws of the
state in which it is executed and, unless the context otherwise requires, all
terms used herein which are defined in Articles 1 and 9 of the Uniform
Commercial Code, as in effect in said state, shall have the meanings therein
stated. If any provision or application of this Agreement is held unlawful or
unenforceable in any respect, such illegality or unenforceability shall not
affect other provisions or applications which can be given effect, and this
Agreement shall be construed as if the unlawful or unenforceable provision or
application had never been contained herein or prescribed hereby. All
representations and warranties contained in this Agreement shall survive the
execution, delivery and performance of this Agreement and the creation and

exercise or enforcement of any Secured Party's rights or remedies. All rights
and remedies of Secured Party shall be cumulative and may be exercised

enforcement of any one such right or remedy shall neither be a condition to nor

shall be deemed sufficiently given if delivered or mailed by registered or
certified mail, postage prepaid, to Pledgor at its address set forth above or at
the most recent address shown on Secured Party's records. Secured Party's duty

safekeeping such Collateral or, in the case of Collateral in the custody or
possession of a bailee or other third person, exercises reasonable care in the
selection of the bailee or other third person, and Secured Party need not
otherwise preserve, protect, insure or care for any Collateral. Secured Party

Secured Party for all expenses (including reasonable attorneys' fees and legal
expenses) incurred by Secured Party in the protection, defense or enforcement of
the Security Interest, including expenses incurred in any litigation or
bankruptcy or insolvency proceedings. This Agreement shall be binding upon and
inure to the benefit of Pledgor and Secured Party and their respective heirs,
representatives, successors and assigns and shall take effect when signed by
Pledgor and delivered to Secured Party. Except to the extent otherwise required
by law, this Agreement shall be governed by the laws of the state in which it is
executed and, unless the context otherwise requires, all terms used herein which
are defined in Articles 1 and 9 of the Uniform Commercial Code, as in effect in
said state, shall have the meanings therein stated. If any provision or
application of this Agreement is held unlawful or unenforceable in any respect,
such illegality or unenforceability shall not affect other provisions or
applications which can be given effect, and this Agreement shall be construed as
if the unlawful or enforceable provision or application had never been contained
herein or prescribed hereby. All representations and warranties contained in
this Agreement shall survive the execution, delivery and performance of this
Agreement and the creation and payment of the Obligations. If this Agreement is
signed by more than one person as Pledgor, the term "Pledgor" shall refer to
each of them separately and to both or all of them jointly; all such persons

                                             ADDITIONAL TERMS OF THE SECURITY AGREEMENT


GENERALLY - This agreement secures this note and any other debt I have with you, now or later. However, it will not secure other
debts if you fail with respect to such other debts, to make any required disclosure about this security agreement or if you fail to
give any required notice of the right of rescission. If property described in this agreement is located in another state, this
agreement may also, in some circumstances, be governed by the law of the state in which the Property is located.

OWNERSHIP AND DUTIES TOWARD PROPERTY - I represent that I own all of the Property, or to the extent this is a purchase money
security interest I will acquire ownership of the Property with the proceeds of the loan. I will defend it against any other claim.
Your claim to the Property is ahead of the claims of any other creditor. I agree to do whatever you require to protect your security
interest and to keep your claim in the Property ahead of the claims of other creditors. I will not do anything to harm your
position.

         I will keep books, records and accounts about the Property and my business in general. I will let you examine these
records at any reasonable time. I will prepare any report or accounting you request, which deals with the Property.

         I will keep the Property in my possession and will keep it in good repair and use it only for the purpose(s) described on
page 1 of this agreement. I will not change this specified use without your express written permission. I represent that I am the
original owner of the Property and, if I am not, that I have provided you with a list of prior owners of the Property.

         I will keep the Property at my address listed on page 1 of this agreement, unless we agree I may keep it at another
location. If the Property is to be used in another state, I will give you a list of those states. I will not try to sell the
Property unless it is inventory or I receive your written permission to do so. If I sell the Property I will have the payment made
payable to the order of you and me.

         You may demand immediate payment of the debt(s) if the debtor is not a natural person and without your prior written
consent; (1) a beneficial interest in the debtor is sold or transferred, or (2) there is a change in either the identity or number
of members of a partnership, or (3) there is a change in ownership of more than 25 percent of the voting stock of a corporation.

         I will pay all taxes and charges on the Property as they become due. You have the right of reasonable access in order to
inspect the Property. I will immediately inform you of any loss or damage to the Property.

         If I fail to perform any of the duties under this security agreement, or any mortgage, deed of trust, lien or other
security interest, you may without notice to me perform the duties or cause them to be performed. Your right to perform for me
shall not create an obligation to perform and your failure to perform will not preclude you from exercising any of your other
rights under the law or this security agreement.

PURCHASE MONEY SECURITY INTEREST - For the sole purpose of determining the extent of a purchase money security interest arising
under this security agreement: (a) payments on any nonpurchase money loan also secured by this agreement will not be deemed to
apply to the Purchase Money Loan, and (b) payments on the Purchase Money Loan will be deemed to apply first to the nonpurchase
money portion of the loan, if any, and then to the purchase money obligations in the order which the items of collateral were
acquired or if acquired at the same time, in the order selected by you. No security interest will be terminated by application of
this formula. "Purchase Money Loan" means any loan the proceeds of which, in whole or in part, are used to acquire any collateral
securing the loan and all extensions, renewals, consolidations and refinancing of such loan.

PAYMENTS BY LENDER - You are authorized to pay, on my behalf, charges I am or may become obligated to pay to preserve or protect
the secured property (such as property insurance premiums). You may treat those payments as advances and add them to the unpaid
principal under the note secured by this agreement or you may demand immediate payment of the amount advanced.

INSURANCE - I agree to buy insurance on the Property against the risks and for the amounts you require and to furnish you
continuing proof of coverage. I will have the insurance company name you as loss payee on any such policy. You may require added
security if you agree that insurance proceeds may be used to repair or replace the Property. I will buy insurance from a firm
licensed to do business in the state where you are located. The firm will be reasonably acceptable to you. The insurance will last
until the Property is released from this agreement. If I fail to buy or maintain the insurance (or fail to name you as loss payee)
you may purchase it yourself.

WARRANTIES AND REPRESENTATIONS - If this agreement includes accounts, I will not settle any account for less than its full value
without your written permission. I will collect all accounts until you tell me otherwise. I will keep the proceeds from all the
accounts and any goods which are returned to me or which I take back in trust for you. I will not mix them with any other property
of mine. I will deliver them to you at your request. If you ask me to pay you the full price on any returned items retaken by
myself, I will do so.

         If this agreement covers inventory, I will not dispose of it except in my ordinary course of business at the fair market
value for the Property, or at a minimum price established between you and me.

         If this agreement covers farm products I will provide you, at your request, a written list of the buyers, commission
merchants or selling agents to or through whom I may sell my farm products. In addition to those parties named on this written
list, I authorize you to notify at your sole discretion any additional parties regarding your security interest in my farm
products. I remain subject to all applicable penalties for selling my farm products in violation of my agreement with you and the
Food Security Act. In this paragraph the terms farm products, buyers, commission merchants and selling agents have the meanings
given to them in the Federal Food Security Act of 1985.

REMEDIES - I will be in default on this security agreement if I am in default on any note this agreement secures or if I fail to
keep any promise contained in the terms of this agreement. If I default, you have all of the rights and remedies provided in the
note and under the Uniform Commercial Code. You may require me to make the secured property available to you at a place which is
reasonably convenient. You may take possession of the secured property and sell it as provided by law. The proceeds will be applied
first to your expenses and then to the debt. I agree that 10 days written notice sent to my last known address by first class mail
will be reasonable notice under the Uniform Commercial Code. My current address is on page 1. I agree to inform you in writing of
any change of my address.

FILING - A carbon, photographic or other reproduction of this security agreement or the financing statement covering the Property
described in this agreement may be used as a financing statement where allowed by law. Where permitted by law, you may file a
financing statement which does not contain my signature, covering the Property secured by this agreement.

   Any person who signs within this box does so to give you a security interest in the Property described on this page. This
   person does not promise to pay the note. "I" as used in this security agreement will include the borrower and any person
   who signs within this box.

</TABLE>
<PAGE>   15
                          ADDITIONAL TERMS OF THE NOTE

DEFINITIONS - As used on pages 1 and 2, "[X]" 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 in which you are located will govern
this agreement. Any term of this agreement 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.

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 sum outstanding at that time. 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 in this note
(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 interest
rate on this note. You do not guarantee by selecting this index, or the margin,
that the interest rate on this note will be the same rate you charge on any
other loans or class of loans yo make to me or other borrowers.

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 on page 2.

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.

SET-OFF - I agree that you may set off any amount due and payable under this
note against any right I have to receive money from you.

         "Right to receive money from you" means:

         (1) any deposit account balance I have with you;

         (2) any money owed to me on an item presented to you or in your
             possession for collection or exchange; and

         (3) any repurchase agreement or other nondeposit obligation.

         "Any amount due and payable under this note" means the total amount of
which you are entitled to demand payment under the terms of this note at the
time you set off. This total includes any balance the due date for which you
properly accelerate under this note.

         If my right to receive money from you is also owned by someone who has
not agreed to pay this note, your right of set-off will apply to my interest in
the obligation and to any other amounts I could withdraw on my sole request or
endorsement. Your right of set-off does not apply to an account or other
obligation where my rights are only as a representative. It also does not apply
to any Individual Retirement Account or other tax-deferred retirement account.

         You will not be liable for the dishonor of any check when the dishonor
occurs because you set off this debt against any of my accounts. I agree to
hold you harmless from any such claims arising as a result of your exercise of
your right to set-off.

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 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 - 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 unpaid
             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.

         (6) You may make use of any remedy given to you in any agreement
             securing this note.

         By selecting any one or more of these remedies you do not give up your
right to use later any other remedy. By waiving your right to declare an event
to be a default, you do not waive your right to consider later the event 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 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 porion 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.

CREDIT INFORMATION - I agree and authorize you to obtain credit information
about me from time to time (for example, by requesting a credit report) and to
report to others your credit experience with me (such as a credit reporting
agency). 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.
