</Table>
                                                *less any voluntary reduction(s)

The Company may, by written notice received by CoBank at least 15 days prior
to the end of any Commitment Period, irrevocably reduce the Commitment Amount
for the duration of that Commitment Period. Any such voluntary reduction
shall be effective 10 days after receipt of such written notice by CoBank
(or, if such day is not a day CoBank is open for business, then on the next
business day of CoBank), and shall not affect any subsequent Commitment
Period. In no event may the Company request a voluntary reduction that would
reduce the Commitment to an amount less than the outstanding principal
balance.

The Commitment shall expire on March 31, 2005, or such later date as CoBank
may, in its sole discretion, authorize in writing. Within the limits of the
Commitment, the Company may borrow, repay pursuant to the terms hereof, and
reborrow.

         SECTION 2. PURPOSE. The purpose of the Commitment is to finance the
inventory and receivables referred to in the Borrowing Base Report.

         SECTION 3. TERM. The term of the Commitment shall be as stated in
Section 1.

<Page>

         SECTION 4. INTEREST. The Company agrees to pay interest on the
unpaid principal balance of each loan in accordance with one or more of the
following interest rate options, as selected by the Company:

         (A) VARIABLE RATE OPTION. At a rate per annum equal at all times to
the rate of interest established by CoBank on the first Business Day of each
week. The rate established by CoBank may not exceed CoBank's National
Variable Rate (as hereinafter defined) on that day, and shall be effective
until the first Business Day of the next week. Each change in the rate shall
be applicable to all balances subject to this option and information about
the then current rate shall be made available upon telephonic request. For
purposes hereof, the National Variable Rate shall mean the rate of interest
established by CoBank from time to time as its National Variable Rate, which
Rate is intended by CoBank to be a reference rate and not its lowest rate.
The National Variable Rate will change on the date established by CoBank as
the effective date of any change therein and CoBank agrees to notify the
Company promptly after any such change.

         (B) FIXED RATE OPTION. At a fixed rate per annum to be quoted by
CoBank in its sole discretion in each instance. Under this option, rates may
be fixed on such balances and for such periods (including periods extending
beyond the maturity date of the loans (as set forth in Section 5 hereof)) as
may be agreeable to CoBank in its sole discretion in each instance. In the
event CoBank consents to one or more balances being fixed for a period or
periods extending beyond the maturity date but the Commitment is not renewed,
then each such balance shall be due and payable on the last day of its fixed
rate period and Section 5 hereof shall, for each such balance, be deemed
amended accordingly.

The Company shall select the applicable rate option at the time it requests a
loan hereunder and may, on any Business Day, elect to convert balances
bearing interest at the variable rate option to the fixed rate option. In
addition, prior to the expiration of any fixed rate period, the Company may,
subject to Section 12 of the MLA, repay any fixed rate balance, convert any
fixed rate balance to the variable rate option, or refix the rate at a new
rate to be quoted by CoBank. Upon the expiration of any fixed rate period,
the Company may, subject to the terms hereof, refix the rate or convert the
rate to the variable rate option. In the absence of any such election,
interest shall automatically accrue at the variable rate option. All
elections provided for herein shall be made telephonically or in writing and
must be received by 12:00 Noon Company's local time. 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.

         SECTION 5. PROMISSORY NOTE. The Company promises to repay on the
date of any reduction in the Commitment the amount by which the outstanding
principal balance exceeds the available Commitment and to repay in full the
unpaid principal balance of the loans on the first CoBank business day after
the expiration of the Commitment. In addition to the above, the Company
promises to pay interest on the unpaid principal balance of the loans at the
times and in accordance with the provisions set forth in Section 4 hereof.
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.

                                      2

         SECTION 6. BORROWING BASE REPORTS, ETC. The Company agrees to
furnish a Borrowing Base Report to CoBank at such times or intervals as
CoBank may from time to time request. Until receipt of such a request, the
Company agrees to furnish a Borrowing Base Report to CoBank within 45 days
after each month end calculating the Borrowing Base as of the last day of the
month for which the Report is being furnished. However, if no balance is
outstanding hereunder on the last day of such month, then no Report need be
furnished. Regardless of the frequency of the reporting, if at any time the
amount outstanding under the Commitment exceeds the Borrowing Base, the
Company shall immediately notify CoBank and repay so much of the loans as is
necessary to reduce the amount outstanding under the Commitment to the limits
of the Borrowing Base.

         SECTION 7. LETTERS OF CREDIT. In addition to loans and if agreeable
to CoBank in its sole discretion in each instance, the Company may utilize
the Commitment to open irrevocable letters of credit for its account. Each
letter of credit shall reduce the amount available under the Commitment by
the maximum amount capable of being drawn thereunder. The rights and
obligations of the parties with respect to each letter of credit will be
governed by the Reimbursement Agreement attached hereto as Exhibit B (which
rights and obligations shall be in addition to the rights and obligations of
the parties hereunder and under the MLA). Notwithstanding the foregoing or
any other provision hereof, the maximum amount capable of being drawn under
each letter of credit must be statused against the Borrowing Base in the same
manner as if it were a loan, and in the event that (after repaying all loans)
the maximum amount capable of being drawn under the letters of credit exceeds
Borrowing Base, then the Company shall immediately notify CoBank and pay to
CoBank (to be held as cash collateral) an amount equal to such excess.

         SECTION 8. COMMITMENT FEE. In consideration of the Commitment, the
Company agrees to pay to CoBank a commitment fee on the average daily unused
portion of the Commitment at the rate of 1/4 of 1% per annum (calculated on a
360 day basis), payable monthly in arrears by the 20th day following each
month. Such fee shall be payable for each month (or portion thereof)
occurring during the original or any extended term of the Commitment. For
purposes of this Section 8, the Commitment shall mean the amounts provided in
Section 1 above for the applicable Commitment Period, irrespective of the
Borrowing Base.

         IN WITNESS WHEREOF, the parties have caused this Supplement to be
executed by their duly authorized officers as of the date shown above.

                            BULK REFINED AND BLEACHED
                          SOYBEAN OIL SUPPLY AGREEMENT

         This BULK REFINED AND BLEACHED SOYBEAN OIL SUPPLY AGREEMENT (this
"AGREEMENT"), dated as of January 15, 2002, by and between South Dakota
Soybean Processors, 100 Caspian Ave., Volga, South Dakota 57071, a South
Dakota co-operative association (hereinafter referred to as "SELLER") and ACH
Food Companies, Inc., 7171 Goodlett Farms Parkway, Cordova, Tennessee 38018,
a Delaware corporation (hereinafter referred to as "BUYER").

                                   WITNESSETH:

         WHEREAS, BUYER desires to obtain from SELLER a continuing supply of
refined, bleached soybean oil (the "Product" or "Products") as more
particularly described in the attached Exhibit A to this Agreement during the
period hereinafter described, and SELLER desires to sell the Product to the
BUYER on the terms hereafter provided.

         NOW THEREFORE, in consideration of the above premises and the mutual
covenants herein contained, the parties agree as follows:

1.       PRODUCTS

         (A) Subject to the terms and conditions of this Agreement, SELLER
shall sell the Products to BUYER, and BUYER shall purchase the Products from
SELLER. It is the intent of the parties that the Products will be produced by
SELLER at the Facility (as defined in Section 3(A) hereof); however, if the
SELLER is unable to meet its requirements under this Agreement, SELLER shall
obtain the Products from another source acceptable to BUYER, which acceptance
shall not be unreasonably withheld, and all other terms and provisions of
this Agreement including pricing and delivery shall remain the same.

         (B) All items as detailed in Exhibit A "Specifications for Products"
are "At Time of Delivery" or at "Time of Shipment" as noted in Exhibit A.
Specifications may be amended at any time by mutual consent of BUYER and
SELLER following a documented change to Exhibit A.

         (C) SELLER certifies that the Products meet Circle U Kosher
certification requirements and shall provide all paperwork reasonably
required by BUYER.

         (D) BUYER will accept Products on the basis of accompanying
Certificate of Analysis after running basic analysis on Products, such as
Peroxide Value, Free Fatty Acid, Color and Iodine Value. It is understood
that BUYER will immediately use the Products in further processing or
shipments to its customers.

         (E) In consideration of this Agreement and the sale of the Equipment
(as defined in the Purchase Agreement), SELLER agrees that during the Term,
the BUYER shall be the sole and exclusive buyer of the Product from the
SELLER for use in food application. SELLER may from

<Page>

time to time sell excess crude or crude de-gummed soybean oil to persons
other than BUYER, provided that the SELLER meets its obligation to provide
Product to the Buyer in the volumes provided in this Agreement.

2.       VOLUMES

         (A) During the Term, BUYER will purchase from SELLER, and SELLER
will sell to BUYER, no less than 290 million pounds of the Product during
each Agreement Year (the "Minimum"). The term "Agreement Year", as used in
this Agreement, shall mean the 12-month period commencing on the First
Shipment Date (as defined in Section 8(A) hereof), and each 12-month period
thereafter during the Term. During the term of the first year the SELLER's
sales minimum of 290 million pounds will be adjusted to reflect actual
shipments made during the first three months after the First Shipment Date.

         (B) BUYER will provide SELLER with anticipated annual demands for
the Product as set forth in Exhibit B. SELLER agrees that it shall be able to
supply up to FIVE MILLION FIVE HUNDRED AND SEVENTY THOUSAND (5,570,000)
pounds of the Product per week (or TWO HUNDRED NINETY MILLION (290,000,000)
pounds of the Product per Agreement Year) should BUYER order such volumes.
BUYER agrees to provide SELLER with at least fourteen (14) days prior written
notice of a Purchase Order in excess of FOUR MILLION (4,000,000) pounds of
the Product in any week.

         (C) If during any Agreement Year BUYER does not purchase (as defined
in section 4A hereof) at least 270 million pounds of Product, BUYER shall pay
to SELLER, within thirty (30) days after expiration of such Agreement Year,
an amount equal to the product of $0.0023 multiplied by the positive
difference remaining after subtracting from 270 million pounds the amount of
Product purchased by BUYER for such Agreement Year.

         (D) If during any calendar month the BUYER does not purchase at
least 22.5 million pounds of the Product, the SELLER may sell refined and
bleached soybean oil in a volume equivalent to the volume of the Unpurchased
Product upon a five (5) day written notice to BUYER. Within such five (5) day
period, BUYER may, upon written notice to SELLER, elect to purchase any of
the Unpurchased Product. SELLER shall sell the Unpurchased Product at its
market price. If the Unpurchased Product is sold for less than the purchase
price for the Product as set forth in Exhibit B, BUYER shall pay SELLER the
shortfall within twenty-five (25) days from the date of SELLER's invoice
therefor. "Unpurchased Product" means refined and bleached soybean oil in an
amount (expressed in pounds) equal to the positive difference remaining after
subtracting from 22.5 million pounds the number of pounds of Product
purchased by BUYER during the calendar month in question.

3.       PRODUCTION FACILITY

         (A) SELLER intends to fulfill its obligations under this Agreement
by refining and bleaching soybean oil in a facility (the "Facility") to be
constructed and owned by SELLER and to be located in Volga, South Dakota.
SELLER shall commence construction of the Facility promptly after execution
and delivery of this Agreement by BUYER and shall achieve Substantial

<Page>

Completion of the Facility (as hereinafter defined) no later than September
1, 2002 (the "Completion Date"). "Substantial Completion of the Facility
means (i) completion of the construction of the Facility (including without
limitation installation of all trade fixtures and equipment, including
without limitation the Equipment, as defined in Section 3(B) hereof)
substantially in accordance all applicable laws and ordinances, such that
SELLER is capable of operating an RB soybean oil refinery at the Facility for
production of the Product in the volumes required by this Agreement, and (ii)
the issuance by the governmental authority having jurisdiction of a
certificate of occupancy or similar certificate or permit for the Facility.
The Completion Date shall be extended one day for each day Substantial
Completion of the Facility is delayed by an Excusable Cause or a Labor Cause,
(as defined in Section 14(N) hereof), provided that in no event shall the
Completion Date be extended for any reason beyond October 1, 2002. If SELLER
fails to achieve Substantial Completion of the Facility on the Completion
Date, as the same may be extended in accordance with the foregoing
provisions, BUYER may thereafter terminate this Agreement effective thirty
(30) days after the Completion Date by giving written notice thereof to
SELLER within such thirty (30) day period. If BUYER so terminates this
Agreement, then within fifteen (15) days after the effective date of such
termination, SELLER shall pay BUYER an amount equal to the Fair Market Value
(as defined in Section 17 hereof) of the Equipment. If BUYER does not so
terminate this Agreement, then until such time as SELLER achieves Substantial
Completion of the Development (the "Delay Period"), SELLER shall be
responsible for BUYER's Cost to Cover (as defined in Section 6(D) hereof)
with respect to the Product that BUYER would have ordered from SELLER during
the Delay Period.

         (B) BUYER is the owner of certain soybean oil refining equipment and
related fixtures located at BUYER's facility in Columbus, Ohio (the "Ohio
Facility"), as more fully described in Exhibit C attached hereto and made a
part hereof (the "Equipment"). Upon execution and delivery by SELLER and
BUYER, BUYER shall sell the Equipment to SELLER, and SELLER and BUYER shall
execute and deliver to each other counterpart copies of the Purchase
Agreement in the form attached hereto as Exhibit D. SELLER shall provide
BUYER no less than fifteen (15) days' prior written notice (the "Equipment
Removal Notice") of SELLER's desire to remove the Equipment from its current
location and install the Equipment at the Facility. BUYER shall allow SELLER
such access as SELLER shall reasonably require to remove the Equipment.
Notwithstanding the foregoing, if BUYER sells the Ohio Facility prior to
BUYER's receipt of the Equipment Removal Notice, SELLER shall be obligated to
remove the Equipment from the Ohio Facility no later than thirty (30) days
after receipt of written notice from BUYER of such sale.

4.       PRODUCT SCHEDULING

         (A) On each Wednesday during the term of this Agreement, BUYER shall
deliver to SELLER BUYER's standard form of purchase order ("Purchase Order")
for the shipment week commencing on the following Monday, and a good faith
forecast of BUYER'S purchases of Product for the following three weeks. Each
Purchase Order will specify the quantity for the following week. BUYER may
designate delivery destinations other than those listed in Exhibit B only by
mutual written consent of the parties and only after appropriate freight
adjustments have been agreed upon by both parties. For all purposes under
this Agreement, BUYER shall be deemed to "purchase" the Product upon delivery
of a Purchase Order as provided in this paragraph.

<Page>

         (B) Not less than once every three months during the term of this
Agreement, BUYER shall furnish SELLER a good faith forecast of its Product
requirements for the next six (6) months. Such forecasts and the estimates
given with the Purchase Orders are not firm commitments of BUYER to order or
purchase Products, but are provided only as a guide to assist SELLER in
scheduling production.

5.       WARRANTIES REGARDING PRODUCTS

         (A) LIMITED WARRANTIES. SELLER warrants that the Products sold under
this Agreement shall conform in all material respects to each of the
following: (i) the specifications attached hereto as Exhibit A, as amended
from time to time by agreement of the parties; (ii) all current good
manufacturing practices; and (iii) the Food and Drug Guarantee attached
hereto as Exhibit E.

         (B) CERTIFICATION OF ANALYSIS. Certificates of Analysis will be
faxed to BUYER's facilities prior to the shipment of rail car and shall
specify values for the first ten tests contained in the specifications. All
tests shall be run according to Association of Oil Chemists Society ("AOCS")
methods unless otherwise agreed to in writing by both parties. A referee
laboratory agreed to by both parties shall settle discrepancies in Product
quality results.

         (C) COMPLIANCE WITH LAWS. SELLER warrants that it shall comply at
all times with all federal, state and local laws, rules, regulations,
ordinances codes, and orders applicable to SELLER's performance of its
obligations hereunder, as well as with other legal obligations set forth in
this Agreement.

6.       SHIPPING

         (A) SELLER shall be responsible for tracking, managing and paying
for freight from time of shipment to delivery to the applicable BUYER's
facility. Shipment of the Product will be within one day of the date
specified on the Purchase Order. All freight shall be prepaid F.O.B. BUYER's
facility with title and risk of loss transferred to BUYER upon BUYER's
receipt of the Product. SELLER will deliver the Product to the BUYER's
facility in its own rail cars; however, if conditions warrant, upon mutual
agreement alternate transportation methods will be allowed.

         (B) DEFECTIVE PRODUCTS. If any Products shipped to a BUYER facility
fail to comply with the provisions of Section 5(A) ("Defective Product"), the
BUYER facility may refuse to accept delivery of such Defective Product and
such Defective Product shall be set aside for inspection by SELLER and SELLER
agrees to promptly replace any Defective Product. Each BUYER facility shall
handle such Defective Products in accordance with SELLER's reasonable
instructions so as to minimize the extent of any such costs. If, upon
reinspection of such Product, it is determined that such Product was not
Defective Product, BUYER shall reimburse SELLER for all reasonable costs
incurred by SELLER in replacing such Product, including without limitation,
shipping and handling costs.

         (C) NORMAL SHIPMENT TIMES. Each Purchase Order shall specify the
shipment date and the desired delivery date (hereinafter referred to as
"DDD"). SELLER shall ensure that the Product arrives at BUYER facilities on
the DDD and shall be liable to BUYER for any Cost of Cover (as

<Page>

defined in Section 6(D) below) BUYER incurs as a result of SELLER's failure
to ship the Product according to the Purchase Order. In the event SELLER does
not ship at designated times (using shipment to arrive beyond DDD), SELLER
shall be responsible for substituting truck deliveries at SELLER's expense.
In the event the railroad fails to deliver a railroad car to BUYER and
shipments were made on time in accordance with BUYER's Purchase Order, SELLER
shall work with BUYER to arrange for timely truck deliveries to alleviate
BUYER inventory shortfall. BUYER shall be responsible for truck freight
differentials.

         In the event that BUYER desires to make a change to the shipment
date, DDD, or other requirements of the Purchase Order on less than seven (7)
days notice to SELLER, SELLER shall use diligent efforts to accommodate such
change provided that BUYER shall reimburse SELLER for any additional costs
incurred by SELLER as a result of such accommodation. SELLER shall advise
BUYER whether or not it can meet the revised ship date. If it advises that it
can meet the ship date and then fails to do so, it shall reimburse BUYER for
any Cost to Cover as referenced in Section D below. If SELLER advises it
cannot meet the revised ship date, then BUYER shall be free to cancel such
order and purchase the Product elsewhere, and SELLER shall not be responsible
for BUYER's Cost to Cover.

         (D) If SELLER notifies BUYER that it is unable to deliver Product on
the DDD Specified in the Purchase Order, and such notice does not include
SELLER's undertaking to ship such Products by an alternate method with
reasonably acceptable delivery date, BUYER shall be free to cancel such order
(either by written notice to SELLER or by prior oral notice to SELLER
followed by written confirmation of same) and purchase such Product (the
"Covered Product") from any other reasonable source. In such event, SELLER
shall pay to BUYER, upon receipt of BUYER'S invoice therefor, an amount equal
to the excess of the price to BUYER of such Covered Product over the price
which BUYER would have paid had it purchased the Covered Product from SELLER
pursuant to this Agreement (the "Cost to Cover") plus reasonable, documented
out-of pocket costs incurred by BUYER as a result of SELLER's failure to
deliver Product such as:

                  (i) any BUYER customer charges for: (a) downtime due to
         late/short shipments; (b) packaging line downtime; (c) overtime; and

                  (ii) BUYER's packaging line downtime; overtime; and customer
         charges for late/short shipments; and

                  (iii) LTL freight charges and additional freight charges.

         (E) DEMURRAGE. SELLER has the right to charge demurrage br those
rail cars unreasonably held beyond five (5) days at the rate of $30 per rail
car per day beginning on day six (6), provided rail cars arrive on a
scattered basis as shipped. BUYER shall not be responsible for, and SELLER
shall pay when due, all demurrage and other charges resulting from "slamming"
by the carrier.

7.       PRODUCT PRICING AND PAYMENT TERMS

         (A) PRICING FOR PRODUCTS. Refining Premiums as shown in Exhibit B
(attached hereto and incorporated herein by reference) are guaranteed for a
period of five (5) years from First Shipment Date (as defined in Section 8(A)
hereof. For the final three (3) years of the Initial Term (as defined in
Section 8(A) hereof), Refining Premiums shall be determined in accordance
with Section 8(A) as if such final three (3) years were a Renewal Term,
provided that negotiations with respect to Refining Premiums shall commence
no later than six (6) months prior to the end of the first five (5) year
period of the Initial Term. SELLER has the right to request an increase in
Refining Premiums for the final three (3) years of the Initial Term, and such
a request shall be made no later than six (6) months prior to the end of the
first five (5) year period of the Initial Term. BUYER and SELLER will enter
into good faith negotiations and any such increase shall only be applicable
to substantiated increases in operating costs, such as costs of labor,
energy, supplies and material, safety and environmental, or landfill, or a
difference in the value of refined bleached byproducts (such as lecithin and
soapstock). In the event the parties are unable to agree on any price
increases prior to the end of the first five (5) year period of the Initial
Term, then the price in effect for the Products in the preceding year will
continue in effect for the succeeding year, at the end of which this
Agreement shall automatically terminate.

         (B) PAYMENT TERMS. SELLER shall invoice BUYER for Products upon
shipment thereof, and such invoice shall be due and payable twenty-five (25)
days from the date of the invoice.

8.       TERM, EVENTS OF DEFAULT AND TERMINATION

         (A) LENGTH OF TERM. The term of this Agreement (the "Initial Term")
shall commence on the date of signature of this Agreement by both parties,
and shall expire eight (8) years after the date of the first shipment of
Product ("First Shipment Date"), unless terminated earlier in accordance with
the provisions of this Agreement, and shall be renewable by BUYER for five
(5) subsequent periods of three (3) years each. SELLER will confirm the First
Shipment Date in writing within fifteen (15) days after the date of such
first shipment. BUYER may renew this Agreement by giving SELLER no less than
eighteen (18) months prior written notice. Upon SELLER's receipt of such
notice, SELLER and BUYER shall begin to negotiate in good faith with respect
to the applicable three-year renewal period ("Renewal Term"). Such
negotiations shall continue for a period of not less than six (6) months,
unless the parties reach agreement prior to the expiration of such six (6)
month period. The Initial Term, as the same may be extended by one or more of
the Renewal Terms, is referred to herein as the "Term." In the event the
parties are unable to reach agreement at the end of such six (6) month
period, then the price in effect in the preceding year will continue in
effect for the succeeding year, at the end of which, this Agreement shall
automatically terminate.

         (B) EVENTS OF DEFAULT. Each of the following shall constitute an
Event of Default hereunder:

                  (i) A material breach by the other party of any of the terms
         or conditions of this Agreement which (a) is not corrected within
         thirty (30) days after receipt of written

<Page>

         notification thereof, if correctable within such thirty (30) days;
         or (b) if it is not correctable within such thirty (30) days, the

         composition, readjustment, liquidation, dissolution, bankruptcy, or
         similar relief under any other present or future United States or
         other statute, law or regulation, whether or not resulting in the

price of the Equipment and shall not constitute a penalty. The unamortized

amortized, using a straight line method, over the first five Agreement Years,
without interest.

business hours and under reasonable circumstances, including prior notice
(which notice shall include communications with SELLER regarding BUYER's
concern), to only those portions of the storage, production, and other
facilities of SELLER which are involved in the production of Product
hereunder. At SELLER's option, BUYER's representative shall be accompanied by

procedures, practices or the like used by SELLER with respect to its services
hereunder fail to conform to appropriate procedures and processes, SELLER
shall immediately take appropriate corrective actions (which may include
suspension of SELLER'S services hereunder) for those items which represent a
public health or safety issue and shall promptly take appropriate corrective
actions (which may include suspension of SELLER'S services hereunder) for

of each report related thereto, and SELLER shall allow BUYER and its
representatives access to such reports for visual review only.

         (C) NO DUTY TO INSPECT. BUYER shall be under no obligation to

released by BUYER's acceptance of delivery of Product or by any inspection
thereof or by payment therefore.

and all reasonable efforts to cure any Excusable Cause preventing its

party shall (a) promptly notify the other party of the possibility of such
Excusable Cause, and (b) if the notifying party is SELLER, use its
commercially reasonable efforts to assist BUYER in procuring Products from

either party, shall be referred to representatives of the parties for
decision, each party being represented by a senior executive officer who has
no direct operational responsibility for the matters contemplated by this
Agreement (the "Representatives"). The Representatives shall promptly meet in

                          CONTINUING PURE FOOD GUARANTY

In consideration of purchases from SELLER by ACH Food Companies, Inc.
("BUYER") of articles subject to the Federal Food, Drug, and Cosmetic Act,
the article comprising each shipment or other delivery hereafter made by
SELLER to or on the order of BUYER is guaranteed, as of the date of such
shipment or delivery, to be, on such date, (a) not adulterated or misbranded
within the meaning of said Federal Act; (b) not an article which may not,
under the provisions of Sections 404 and 505 of said Federal Act, be
introduced into interstate commerce; (c) not adulterated or misbranded within
the meaning of laws or ordinances of the state or city to which such article
is shipped by SELLER, the adulteration and misbranding provisions of which
are substantially the same as those found in said Federal Act; and (d) where
applicable, in compliance with the Federal Insecticide, Fungicide, and
Rodenticide Act.

This Guaranty is executed by SELLER subject to the condition that if an
article is delivered under a label designed or furnished by BUYER, SELLER's
responsibility for misbranding shall be limited to that resulting from the
failure of the article to conform to the standard, if any, for the product,
the purchase specifications or the statements contained on such label.

This Guaranty replaces any continuing guaranties described in paragraph 1
previously given by SELLER to BUYER and shall continue in effect with respect
to all articles ordered by BUYER from SELLER until such time as it is revoked
in writing by BUYER.
