ITEM 1.  BUSINESS
 
GENERAL
 
    American Crystal is a Minnesota agricultural cooperative corporation owned
by approximately 2,835 sugarbeet growers in the Minnesota and North Dakota
portions of the Red River Valley. (The Red River Valley, the largest sugarbeet
growing area in the United States, forms a band approximately 35 miles wide on
either side of the North Dakota and Minnesota border and extends approximately
200 miles south from the border of the United States and Canada.) The Company
currently processes sugarbeets from a base level of approximately 499,000 acres,
subject to tolerances for overplanting and underplanting established by the
Board of Directors each year. By owning and operating five sugarbeet processing
facilities in the Red River Valley, the Company provides its shareholders with
the ability to process their sugarbeets into sugar and by-products, such as
molasses and beet pulp. The sugar is pooled and then marketed through the
services of a marketing agent under contract with the Company. The sugar
marketing agent, United Sugars Corporation, is a cooperative owned by its
members, American Crystal, Southern Minnesota Beet Sugar Cooperative, Minn-Dak
Farmers Cooperative and United States Sugar Corporation. The Company's molasses,
beet pulp and concentrated separated by-product (CSB) (a by-product of the
molasses desugarization process) are also marketed through a marketing agent,
Midwest Agri-Commodities Company. Midwest Agri-Commodities Company is a
cooperative whose members are the Company, Minn-Dak Farmers Cooperative and
Southern Minnesota Beet Sugar Cooperative. The Company is also one of three
members of ProGold Limited Liability Company, a joint venture which owns a corn
wet-milling plant in Wahpeton, North Dakota.
 
    American Crystal was organized in 1973 by sugarbeet growers to acquire the
business and assets of American Crystal Sugar Company, then a publicly held New
Jersey corporation in operation since 1899.
 
    American Crystal's corporate headquarters are located at 101 North Third
Street, Moorhead, Minnesota 56560 (telephone number (218) 236-4400). Its fiscal
year ends August 31.
 
PRODUCTS AND PRODUCTION
 
    American Crystal is engaged primarily in the production and marketing of
sugar from sugarbeets. American Crystal also markets beet pulp, molasses and
CSB, which are by-products of the sugar it produces, and sugarbeet seed.
 
    American Crystal processes sugarbeets grown by its members in five factories
located in the Red River Valley area of Minnesota and North Dakota. The growing
area is divided into five factory districts, each containing one sugarbeet
processing plant.
 
    The period during which the Company's plants are in operation to process
sugarbeets into sugar and by-products is referred to as the "campaign." During
the campaign, each of the Company's factories is operated twenty-four hours per
day, seven days per week. The campaign is expected to begin in September,
 
                                       2
<PAGE>
when a small portion of the sugarbeet crop is harvested, and continues until the
available supply of beets has been depleted, which generally occurs in April or
May of the following year. Based on current processing capacity, an average
campaign lasts approximately 250 days, assuming normal crop yields.
 
    Once the sugarbeets are harvested, rapid processing is important to maximize
sugar extraction and minimize spoilage. Members transport their crop by truck to
receiving stations designated by the Company and receive a hauling allowance
under the Grower's Contract. Beets are then stored in factory yards and at
outlying piling stations until processed.
 
    American Crystal's total sugar production is presently influenced by the
amount and quality of sugarbeets grown by its members, the processing capacity
of the Company's plants and by the ability to store harvested beets. Most of the
beet harvest is stored in piles. Although frozen sugarbeets may be stored for
extended periods, beets stored in unprotected piles at temperatures above
freezing must be processed within approximately 150 days. In most years,
therefore, the cold weather in North Dakota and Minnesota offers an advantage to
the Company as it permits the outdoor storage of sugarbeets in below-freezing
weather conditions. By contrast, unprotected piles of sugarbeets would
experience cycles of freezing and thawing and, therefore, be subject to some
deterioration.
 
    Subject to such freeze and thaw cycles, beets on the exterior of piles
freeze naturally. Beets near the center of the piles, however, may not freeze
and thus may be subject to spoilage. The Company utilizes a process called
"split pile storage" in which beets from the center of the piles are removed for
processing first. Split pile storage permits more of the stored beets to freeze
naturally.
 
    American Crystal also utilizes a ventilation technique to further reduce
spoilage. In this process, fans circulate air through ventilation channels
constructed within beet piles in order to precool and then deep freeze the
beets. Approximately 21% of an average crop may be stored in ventilated storage
sites. Enclosed cold storage facilities are also used to extend the beet storage
period at each of the Company's factory locations. Enclosed cold storage sites
presently have the capacity to cover approximately 7% of an average crop.
 
    Once the sugarbeets arrive in the factory, the basic steps in producing
sugar from them include: washing; slicing into thin strips called "cossettes";
extracting the sugar from the cossettes in a diffuser; purifying the resulting
"raw juice" and boiling it, first in an evaporator to thicken it and then in
vacuum pans to crystalize the sugar; separating the sugar crystals in a
centrifuge; drying the sugar; storing sugar in bulk form and grading and
screening the crystals for packaging and bulk shipping.
 
    The Company's sugarbeet by-products include molasses and beet pulp. After
the extraction of raw juice from the cossettes, the remaining pulp is dried and
processed into animal feeds. The Company processes approximately one-half of its
molasses through its molasses desugarization facility to extract additional
sugar. The remaining molasses and CSB from the molasses desugarization process
are marketed through Midwest Agri-Commodities Company and are sold primarily to
yeast and pharmaceutical manufacturers and for use in animal feeds.
 
    The Company also has its own Seed Division, which has been in existence
since the 1920's. The goal of the Seed Division is to ensure that the Company's
shareholders have the highest quality sugarbeet hybrids available to maximize
their production. Since the mid-1970s, American Crystal had an effective working
relationship with Danisco Seed of Denmark. In 1998, American Crystal signed a
10-year agreement with Betaseed covering exchange of germplasm, together with
purchasing, product development, production and trademark license agreements.
 
    Betaseed is the US subsidiary of KWS, a German seed company which is one of
the three largest seed companies in the world. The Seed Division markets its
seed to sugarbeet growers in Michigan, Ohio, Montana, Wyoming, Colorado,
Nebraska, Idaho, Oregon, California, Washington and to its own growers in North
Dakota and Minnesota.

RECENT CROPS
 
    The sugarbeet crop grown during 1998 produced a total of approximately 22.2
tons of sugarbeets per acre from approximately 481,000 acres. That production
exceeded the ten-year average of 16.8 tons per acre for the years 1988 through
1997. The sugar content of the 1998 crop was 17.66%, in comparison to a ten-year
average for the applicable period of 17.36%. The Company has begun processing
the sugarbeets produced in the 1998 crop and expects to produce a total of
approximately 27 million hundredweight of sugar from that crop.
 
    The sugarbeet crop grown during 1997 produced a total of approximately 18.5
tons of sugarbeets per acre from approximately 462,000 acres. That production
exceeded 16.9 tons per acre, which is the ten-year average of tons per acre for
the years from 1987 through 1996. The sugar content of the 1997 crop was 17.59%,
in comparison to a ten-year average for the applicable period of 17.39%. The
company produced a total of approximately 21.5 million hundredweight of sugar
from the 1997 sugarbeet crop.
 
    American Crystal's members harvested approximately 8.3 million tons of
sugarbeets from 459,000 acres for the 1996 crop. The approximately 18.1 ton per
acre yield was higher then the then-current 16.8 ton per acre 10 year average.
Sugar content for the 1996 crop was approximately 17.30%, which is 0.07% lower
than the then-current ten year average of 17.37%. Beet processing began on
September 5, 1996 and the Company produced 22.5 million hundredweights of sugar
during the 1996-1997 campaign.
 
    For a discussion of the 1997, 1996 and 1995 crops and results of operations
for fiscal years 1998, 1997 and 1996, see "Management's Discussion and Analysis
of Financial Condition and Results of Operations".
 
MARKET AND COMPETITION
 
    The United States is the world's largest sugar and sweetener complex.
Current US government statistics estimate total US sugar consumption at 183.4
million hundredweight for the year beginning October 1, 1997 and ending
September 30, 1998. For the same period starting October 1996, total consumption
was 182.6 million hundredweight. Comparing the two years shows relatively
marginal demand growth for US sugar sellers. This slowdown in consumption growth
rates is primarily attributable to the decline in the low-fat and non-fat food
trend, which used more sugar in product formulations. Continued substitution of
corn sweeteners for sugar and import leakages have also contributed to the
overall demand slowdown.
 
    Despite evidence of a sugar demand slowdown, the US government forecasts
growth between 1998 and 1999 to be slightly higher than 2%, which is slightly
above trendline and includes consumption increases due to population growth.
Although the Company believes that domestic consumption growth could once again
approach 2% annually over the longer term, recent trends have pressured growth
rates lower and slower growth may be more realistic to assume at the current
time. The US refined sugar market has grown over the past twenty years, despite
the enormous amount of demand lost to the substitution of high fructose corn
syrups for sugar in beverages and certain food products. Non-nutritive
sweeteners such as aspartame have also been developed to substitute for sugar.
While corn and non-nutritive sweeteners constitute a large portion of the
overall sweetener market, the Company believes that the market for sugar will
continue to grow between 1 and 2% per year due to population growth and
increased use of sugar in processed foods.
 
    The substitution of corn sweeteners for sugar not only reduced demand for
sugar in the United States, but also resulted in a high degree of sugar industry
consolidation. In 1978 there were 28 sugar producers and sellers in the US
market. Today there are eight sugar sellers, with over 75% of US sugar market
share concentrated in the top three sellers, all of which are fully integrated
beet and cane suppliers. Given the size of the domestic market, the Company's
(ACSC) sugar production and sales represented 11.8% of the total domestic market
for refined sugar in 1997/98. United Sugars, which sells the Company's
production through a sugar marketing pool, represents approximately 25% share of
the US sugar market.
 
                                       4
<PAGE>
    The Company's main competitors in the domestic market are
Imperial-Holly-Savannah, Tate & Lyle North America, Amalgamated Sugar Company
and California & Hawaiian Sugar Company. Competition in the US industry, because
sugar is a fungible commodity, is primarily based upon price, customer service
and reliability as a supplier.
 
    According to USDA statistics, the Red River Valley is generally one of the
most cost efficient sugarbeet producing areas in the nation. As a result, the
Company's management believes that it possesses the ability to compete
successfully with other producers of sugar in the United States. In the future,
while cost efficiency is a competitive advantage, substitute products for sugar
and sugar imports could have a material and adverse effect on the Company's
operations.
 
MARKETING, CUSTOMERS AND PRICES
 
    Since January, 1994, American Crystal's sugar has been marketed by United
Sugars Corporation, a cooperative common marketing agency. United Sugars
Corporation was formed in late 1993. Upon completion of the incorporation and
capitalization of United Sugars Corporation, American Crystal entered into a
"Uniform Member Marketing Agreement" with United Sugars Corporation. Under that
agreement, the sugar produced by American Crystal is pooled with sugar produced
by Minn-Dak Farmers Cooperative, and Southern Minnesota Beet Sugar Cooperative
and is then sold through the efforts of United Sugars Corporation. The Company
receives payment for its sugar by receiving its pro rata share of the net
proceeds from the sale of the pooled sugar. The net proceeds of such sales
represent the gross proceeds of sale of the sugar, adjusted for the various
costs and expenses of marketing the pooled sugar, including the Company's pro
rata share of the marketing and sales expenses incurred by United Sugars
Corporation. Any net proceeds from the operation of United Sugars Corporation
are distributed to the various members proportionally.
 
    On December 1, 1997, United States Sugar Corporation (USSC), a grower of
sugar cane and other agricultural products became a member of United Sugars
Corporation. United Sugars Corporation and USSC entered into a Uniform Cane
Sugar Marketing Agreement. Under that agreement, USSC will market all of its
refined sugar through United Sugars Corporation. Existing members of United
Sugars Corporation, including the Company, entered into amended marketing
agreements reflecting the admission of USSC. With the admission of USSC, United
Sugars Corporation is able to distribute both cane sugar and beet sugar, and
distribute sugar to customers over a large geographical area.
 
    The Company's sugar is marketed by United Sugars Corporation primarily to
industrial users such as confectioners, breakfast cereal manufacturers and
bakeries. For the fiscal year ended August 31, 1998, 89.7% (by weight) of the
Company's sugar production was sold to industrial users. The remaining portion
is marketed by United Sugars Corporation through sugar brokers to wholesalers
and retailers under the "Crystal Sugar" brand name and various private labels
for household consumption.
 
    Customers are located primarily in Illinois, Minnesota, Iowa, Wisconsin,
Pennsylvania, Michigan, Indiana, Ohio, Missouri and Tennessee. During fiscal
1998, the Company's 10 largest customers purchased approximately 57.6% (by
weight) of the Company's sugar sold.
 
    The prices at which United Sugars Corporation sells the Company's sugar
fluctuates periodically based on changes in domestic sugar supply and demand.
The largest proportion of American Crystal's sales are contracted one or more
quarters in advance, with the effect of stabilizing fluctuations in revenue from
quarter to quarter. Retail (grocery) products are sold on a spot price basis.
Sugar prices were at a premium in 1996 due to sugarbeet shortages and
insufficient refinery capacity. Sugar prices decreased in 1997 and 1998 due to
increased domestic production, larger import quotas and declining consumption
growth rates.
 
    American Crystal markets dried beet pulp, molasses and CSB through Midwest
Agri-Commodities Company, a cooperative whose members are American Crystal,
Minn-Dak Farmers Cooperative and Southern Minnesota Beet Sugar Cooperative. Beet
pulp is marketed to livestock feed mixers and livestock
 
                                       5
<PAGE>
feeders in the United States and foreign markets. For the year ended August 31,
1998, the majority of American Crystal's pulp production was exported to Japan
and Europe. The market for beet pulp is affected by the availability and quality
of competitive feedstuffs. Beet molasses is marketed primarily to yeast
manufacturers, pharmaceutical houses, livestock feed mixers and livestock
feeders. By-product sales accounted for approximately 10% of the Company's total
revenues during fiscal 1998. This relationship is primarily a function of the
average market prices for sugar, pulp and molasses and is not necessarily
indicative of future relationships between by-product and sugar revenues,
because prices of these commodities fluctuate independently of each other.
 
GOVERNMENT PROGRAMS AND REGULATION
 
    Domestic sugar prices are supported under a program administered by the
USDA. Under the current program, which was initiated in 1981 and extended under
the Food Security Act of 1985, the Food, Agriculture, Conservation and Trade Act
of 1990 and the Federal Agriculture Improvement and Reform Act of 1996 (the
"FAIR Act"), the price of sugar is maintained above the price at which producers
could forfeit sugar to repay nonrecourse loans obtained through the Commodity
Credit Corporation (the "CCC"). The USDA maintains sugar prices without cost to
the U.S. Treasury by regulating the quantity of sugar imports. Under the "Tariff
Rate Quota" implemented October 1, 1990, sugar producing countries are assigned
a fixed quantity of imports duty-free or subject to minimal duties. Unlimited
additional quantities may be imported upon payment of a tariff of 16 cents per
pound prior to shipment. (To date, only minute quantities of sugar have been
imported under this higher tariff level.)
 
    The Uruguay Round agreement under the General Agreement on Tariffs and Trade
(GATT) mandates imports of at least 1,257,000 short tons of sugar per year into
the United States. The FAIR Act maintains an 18 cent per pound loan rate for raw
sugar and a 22.90 cent per pound loan rate for refined beet sugar. Both loan
rates are effective for crop years 1996 through 2002. Price support loans are to
be made on a nonrecourse basis provided that United States sugar imports for
domestic usage exceed 1.5 million short tons raw value in a given fiscal
(October through September) year. Loans made on a nonrecourse basis enable the
sugar processor to forfeit sugar to the CCC if sugar prices are below the loan
rate. If imports during a given year are less than 1.5 million short tons, loans
must be made on a recourse basis, meaning that processors will not be able to
forfeit sugar to the CCC at its full loan value. In order to recover the full
value of a recourse loan, the CCC could require that cash or other assets be
provided in addition to the sugar used as collateral when the loan is made.
Another provision of the FAIR Act is a one cent per pound penalty paid by
processors if the processor defaults on sugar price support loans.
 
    The nature and scope of future legislation affecting the sugar market cannot
be predicted and there can be no assurance that price supports will continue in
their present form. If the price support program, including the Tariff Rate
Quota system described above, were eliminated in its entirety or if the
protection the United States' price support program provides from foreign
competitors were materially reduced, the Company could be materially and
adversely effected. In such a situation, if the Company were not able to adopt
strategies which would allow it to compete effectively in a greatly changed
domestic market for sugar, the adverse affects could impact the Company's
continued viability and the desirability of growing sugarbeets for delivery to
the Company. Such events could significantly impair the value of the shares of
Preferred Stock in which are embodied the right and obligation to deliver
sugarbeets.
 
GROWERS' CONTRACTS
 
    American Crystal purchases virtually all of its sugarbeets from members
under contract with the Company. All members have five-year contracts with the
Company covering the growing seasons of 1998 through 2002 (the "Growers'
Contracts"). Each member will be obligated to enter into a new five-year
contract for subsequent years. In addition, each member has an annual contract
with the Company specifying the number of acres the member is obligated to grow
during that year. Each share of Preferred Stock held by a member entitles that
member to grow one acre of sugarbeets for sale to the Company. The
 
                                       6
<PAGE>
Company's Board of Directors has the discretion to adjust the acreage which may
be planted for each share of Preferred Stock held by the members. However, it is
management's current intention and recommendation to the Board of Directors that
the relationship between shares of Preferred Stock and acres of sugarbeet
production be maintained at a ratio of 1 to 1 for the foreseeable future,
subject to tolerances for overplanting and underplanting established by the
Board each year.
 
    The total price for sugarbeets paid to a member (the "Net Beet Payment") is
based on the "Gross Beet Payment," as adjusted by certain allowances, costs and
deductions. The Gross Beet Payment is the value of recovered sugar from the
beets a member delivers plus the member's share of by-product revenues, minus
the member's share of member business operating costs, including depreciation
and interest. The following allowances, costs and deductions, if applicable, are
used to adjust the Gross Beet Payment to arrive at the Net Beet Payment: hauling
allowance program costs, pre-pile quality premium costs, minimum payment
allowance program costs, tare incentive premium/penalty program and unit
retains. Growers are paid a hauling allowance based on the distance they must
transport beets for delivery to the Company and may also receive minimum beet
payments and an allowance for early delivery of beets prior to the commencement
of the stockpiling of harvested sugarbeets. The costs of these programs are
shared among members on the basis of the net tonnage of beets delivered by each
member.
 
    Under the current Growers' Contracts, payments to members for sugarbeets
must be made in at least three installments: (i) on or about November 15, the
Company pays its members an amount equal to 65% of the Company's estimate of the
grower's Net Beet Payment; (ii) on or about March 31, the Company pays an amount
which combined with the November payment equals 90% of the estimated Net Beet
Payment; (iii) and not more than 15 days after completion and acceptance of the
audit of the Company's annual financial statements, the Company pays the
remainder of the member's Net Beet Payment. Except for unit retains, the Company
must pay to members for their sugarbeets all proceeds from the sale of sugar and
by-products in excess of related member business operating costs, as described
above.

(1) Information provided with respect to net proceeds, gross beet payment, net
    beet payment, tons harvested per acre and sugar content of beets represents
    an average of the financial and production results experienced by the
    Company's members. As described elsewhere in this annual report, the return
    to members for their sugarbeets is based upon the value of the recovered
    sugar from the beets delivered to the Company by each member. As a result of
    variations in the sugar content of the sugarbeets delivered by the various
    members to the Company, the payments received by the various members also
    vary.
 
ENVIRONMENTAL MATTERS
 
    American Crystal is subject to extensive federal and state environmental
laws and regulations with respect to water and air quality, solid waste disposal
and odor and noise control. The Company conducts an on-going and expanding
control program designed to meet these environmental laws and regulations.
American Crystal believes that it is in substantial compliance with applicable
environmental laws and regulations.
 
    The Company received a Notice of Violation from the State of Minnesota on
September 24, 1998 for an accidental discharge of wastewater that allegedly
contaminated a nearby river and caused a fish kill. The Company has responded to
the Minnesota Pollution Control Agency (MPCA) and is awaiting further action by
the MPCA. The accidental discharge occurred when a dike was breached at a
temporary wastewater holding pond the Company had constructed with the approval
of the MPCA. The MPCA has indicated a penalty will be assessed. The final
penalty and corrective actions will be determined when a final stipulation
agreement is drafted. This will occur sometime in December, 1998 or January,
1999. Management believes the outcome of the enforcement action should not have
a material adverse effect on the Company's financial condition.

JOINT VENTURE--PROGOLD LIMITED LIABILITY COMPANY
 
    American Crystal is one of three members of ProGold Limited Liability
Company ("ProGold"). ProGold was formed in July, 1994 as a limited liability
company to serve as a joint venture mechanism for the Company, Minn-Dak Farmers
Cooperative and Golden Growers Cooperative, a North Dakota cooperative
association comprised of corn producers. The joint venture was formed to
construct and operate a corn wet-milling plant capable of processing corn to
produce corn sweeteners (including high fructose corn syrups) and various
by-products. ProGold's plant, which became operational in late 1996, is
currently fully operational and has obtained certification from its significant
customers.
 
    American Crystal contributed a total of approximately $48 million for its
membership interest in ProGold and received a 46% interest in ProGold. Golden
Growers Cooperative contributed approximately $51 million in exchange for a 49%
interest in ProGold, while Minn-Dak Farmers Cooperative made a capital
contribution of approximately $5.2 million in exchange for a 5% interest in
ProGold. Under the terms of the ProGold Member Control Agreement, in each year
after September 1, 1997, the ProGold Board of Governors can require that the
three members of ProGold provide additional capital contributions in an
aggregate amount not to exceed $5 million per year, with each member obligated
to provide a portion of that capital contribution proportionate to its ownership
interest in ProGold. As a result, the Company could be required to make annual
contributions in an amount of up to $2.3 million per year, based on the
Company's ownership of a 46% interest in ProGold. Any other capital
contributions can be required only with the prior written consent of all of
ProGold's members, including the Company.
 
    ProGold and Cargill, Incorporated ("Cargill") have entered into a lease of
ProGold's corn wet-milling plant to Cargill. The lease commenced on November 1,
1997, and will terminate on December 31, 2007. Under the arrangement, the
Company and its ProGold partners will retain ownership of the plant, while
Cargill will operate the plant. ProGold will receive rental payments in a base
amount fixed for each year during the term of the lease. ProGold will also
receive supplemental rent equal to fifty percent (50%) of the amount by which
earnings before taxes from Cargill's operation of the facility exceeds a
contractually-specified base amount. Under the terms of the lease, Cargill has
also entered into a corn supply agreement with ProGold, pursuant to which
ProGold will be obligated to deliver approximately 15.6 million bushels of corn
per fiscal year. Cargill will pay ProGold a market price for any corn delivered
to Cargill under the corn supply agreement. The lease specifies a variety of
alternatives which may take effect upon expiration of the initial term of the
lease. ProGold and Cargill could negotiate a ten year extension of the lease
upon mutually agreeable terms and conditions, ProGold could offer to sell the
facility to Cargill at a fair market value or ProGold could offer to sell
Cargill a fifty percent (50%) ownership interest in ProGold. If the parties are
unable to agree upon the terms and conditions of any such transaction, ProGold
can enter into a similar transaction with a third party. However, in each case,
including a lease of the facility to a third party, Cargill would have the first
right to engage in the proposed transaction upon the same terms as agreed to by
the third party.
 
    If ProGold is successful in generating profits for distribution to is
members, those distributions would become the property of the Company. Under the
Company's Articles of Incorporation and Bylaws, the return, if any, from the
Company's involvement with ProGold would be classified as amounts received from
"non-patronage" sources. The Company's Bylaws currently provide that any
non-patronage net income is to become the property of the Company and is not to
be distributed directly to the members of the Company. Distributions from
ProGold could, in the discretion of the Company's Board of Directors, yield
benefits to the Company's members through such means as future reductions of
annual unit retain amounts, repayment of unit retains in advance of the current
seven year repayment schedule and the use of such returns, if any, for capital
investment in the Company. To date, the Company's Board of Directors has not
adopted any resolutions or made any commitments regarding the distribution of
non-patronage revenues directly to the Company's members or the application of
any such amounts for the indirect benefit of the Company's members. As described
above, any decisions regarding the application of
 
                                       9
<PAGE>
distributions received by the Company from ProGold will be made in the
discretion of the Company's Board of Directors.
 
JOINT VENTURE--CRYSTECH, LLC
 
    Crystech, LLC (Crystech) is a limited liability company formed on May 28,
1998. The Company is a member in Crystech and initially contributed $1,545,000,
or 50% of equity interest to form Crystech. The other 50% member is Newcourt
Capital USA, Inc., a Delaware corporation. As specified by the Limited Liability
Company Agreement, ACS and Newcourt each appointed three members to serve on
Crystech's six member Board of Managers.
 
    Crystech was formed to construct and operate a molasses de-sugarization
facility in Hillsboro, North Dakota. The total cost of the facility is estimated
at $103.0 million. It is anticipated that the plant will have the capacity of
processing 200,000 tons annually of softened molasses for conversion to sugar
extract and other by-products. Construction began in June 1998 and is
anticipated to reach mechanical completion in November 1999. The plant is
anticipated to be in full production approximately 30 days after mechanical
completion.
 
    To fund the construction of the facility, Crystech will obtain significant
amounts of debt financing. Under a Purchase Agreement between Crystech and the
lender group, Crystech Senior Lender Trust agreed to provide term debt to
Crystech in the sum of $86,005,000 via the purchase of notes from Crystech.
Additionally, ACS has agreed to provide $13,905,000 of subordinated debt to
Crystech. To support the construction of the facility, periodic draws from the
trust account are made several times each month during the entire construction
period. These draws are subject to certain approvals by the independent engineer
and Newcourt, as agent for Crystech Senior Lender Trust.
 
    As of August 31, 1998, Crystech was committed to construction costs related
to an Engineering, Procurement and Construction (EPC) Contract totaling $78.9
million. As of August 31,1998, Crystech had incurred $12.7 million related to
this contract. The EPC Contract with the general contractor of the project,
Process Systems Inc. of Memphis, Tennessee, also specifies certain cost
guarantees, and mechanical and performance warranties.
 
    The Company has a 12-year tolling services agreement with Crystech whereby
upon completion of construction, the Company pays for tolling services for
processing beet molasses delivered to Crystech with title and risk of loss
throughout the process maintained by the Company. The tolling agreement may be
terminated by the Company if the specific operational processing performance
required of Crystech in the contract is not achieved.
 
EMPLOYEES
 
    As of August 31, 1998, American Crystal had 1,221 full-time employees, of
which 996 were hourly and 225 were salaried. The Company also had 42 part-time
employees. In addition, the Company employs approximately 1,466 additional
hourly seasonal workers during the sugarbeet harvest and approximately 518
hourly seasonal workers during the remainder of the sugarbeet processing
campaign.
 
    Substantially all of the hourly employees at the factories, including
full-time and seasonal employees, are represented by the American Federation of
Grain Millers, AFL-CIO, and are covered by a collective bargaining agreement
expiring July 31, 1999. Negotiations for a new contract will take place in May,
June, and July of 1999. Office, clerical and management employees are not
unionized, except for certain office employees at the Moorhead and Crookston,
Minnesota, and Hillsboro, North Dakota, factories who are covered by the
collective bargaining agreement with the Grain Millers. The Company considers
its employee relations to be excellent.
 
    Substantially all employees who meet eligibility requirements of age and
length of service are covered by one of the Company's two retirement plans. Plan
A (nonunion employees) and Plan B (union
 
                                       10
<PAGE>
employees) are defined benefit, noncontributory plans. The plans provide for
vesting in five years with benefits for early retirement, normal retirement and
disability or death. The Company's policy is to fund pension costs accrued, and
the plans were fully funded for vested benefits as of February 28, 1998, the end
of the most recent plan year. Union and nonunion employees are also eligible to
participate in 401(k) savings plans.
 
ITEM 2.  PROPERTY AND PROCESSING FACILITIES
 
    American Crystal operates five sugarbeet processing factories in the Red
River Valley. The factories are located in Crookston, East Grand Forks and
Moorhead, Minnesota and Drayton and Hillsboro, North Dakota. American Crystal
owns all of its factories and the land on which they are located. The factories
range in size from 150,000 to 400,000 square feet and have a combined beet
processing capacity, expressed in terms of quantity of sugarbeets which may be
sliced into strips or "cossettes," of approximately 33,300 tons per day. The
Crookston, Minnesota plant has a capacity of 5,300 tons of sugarbeets per day,
the East Grand Forks, Minnesota plant has a capacity of 9,000 tons of sugarbeets
per day and the Moorhead plant has a capacity of 5,400 tons of sugarbeets per
day. The Company's Hillsboro, North Dakota plant has a capacity of 7,700 tons of
sugarbeets per day, while the Drayton, North Dakota plant has a capacity of
5,900 tons of sugarbeets per day. Each of the processing factories includes the
physical facilities and equipment necessary to process sugarbeets into sugar.
Each factory has space for sugarbeet storage, including ventilated and cold
storage sites. Approximately 28% of the sugarbeet crop is stored in either
ventilated storage sites or cold storage facilities. Each processing factory
includes the washing and slicing equipment necessary to cut the sugarbeets into
cossettes, the diffusers necessary to extract sugar from the cossettes in the
form of "raw juice" and the purification systems necessary to remove impurities
from the raw juice. The factories also contain the evaporators and vacuum pans
necessary to thicken the raw juice and then to crystalize the sugar. Each
factory also contains the centrifuges and dryers necessary to complete the
process. The Company's sugar packaging facilities are located at the Moorhead,
Hillsboro, Crookston and East Grand Forks factories. Each of the Company's
facilities is currently operating at or near its capacity.
 
    In 1998 the Company completed a number of capital improvements to its sugar
factories. A $57 million expansion of the Hillsboro processing facility was
completed in September 1998, raising daily capacity to slice sugarbeets from
5,900 to 7,700 tons per day. A $20 million replacement of beet slicing and
diffusion was completed at the East Grand Forks factory. Both projects increased
sugar recovery and processing efficiencies. Two new beet piling sites were
established, seven new beet pilers were added, and twenty-six upgrade kits to
beet pilers were added to allow harvesting of the expanded crop size (acreage).
In addition, 800,000 tons of additional deep freeze storage capacity was added,
which allows extended processing campaigns.
 
    Current capital projects in execution include a $103 million joint venture
to build a molasses desugarization (MDS) plant at the Hillsboro facility to
process the balance of the Company's molasses to extract additional sugar. Also,
a new wastewater treatment plant is being built at Hillsboro to accommodate the
MDS plant and extended campaign processing, plus storage tanks and expansion of
the sugar crystallization station at East Grand Forks to enhance sugar recovery
and allow extended processing.
 
    American Crystal's corporate office is located in a 30,000 square foot,
two-story office building in Moorhead, Minnesota. The Company also has a 100,000
square foot research center situated on approximately 200 acres in Moorhead,
Minnesota. The Company owns both facilities, and owns numerous sites as
sugarbeet receiving and storage stations. All the Company's property, plant and
equipment is mortgaged or pledged as collateral for its indebtedness to the St.
Paul Bank for Cooperatives.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    From time to time and in the ordinary course of its business, the Company is
named as a defendant in legal proceedings related to various issues, including
worker's compensation claims, tort claims and
 
                                       11
<PAGE>
contractual disputes. The Company is currently involved in certain legal
proceedings which have arisen in the ordinary course of American Crystal's
business; the Company is also aware of certain other potential claims which
could result in the commencement of legal proceedings. The Company carries
insurance which provides protection against certain types of claims. With
respect to current litigation and potential claims of which the Company is
aware, the Company's management believes that (i) the Company has insurance
protection to cover all or a portion of any judgments which may be rendered
against the Company with respect to certain claims or actions and (ii) any
judgments which may be entered against the Company and which may exceed such
insurance coverage or which may arise in actions involving potential liabilities
not covered by insurance policies are not likely to have a material adverse
effect upon the Company, or its assets or operations.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
    No matters were submitted to a vote of the Company's shareholders during the
quarter ended August 31, 1998.

                                    PART II
 
ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
         MATTERS
 
    There is no established public market for the Company's Common Stock or
Preferred Stock, as such shares may be held only by farmer-producers who are
eligible for membership in the Company. The Company's shares are not listed for
trading on any exchange or quotation system. Although transfers of the Company's
shares may occur only with the consent of the Board of the Directors, the
Company does not obtain information regarding the transfer price in connection
with such transfers. As a result, the Company is not able to provide information
regarding the prices at which the Company's shares have been transferred.
 
    Because the number of acres of sugarbeets a member may grow for sale to the
Company is directly related to the number of shares of Preferred Stock owned, a
limited, private market for Preferred Stock exists. However, it is not
anticipated that a general public market for the Company's shares of Common
Stock or Preferred Stock will develop due to the limitations on transfer and the
various membership requirements which must be satisfied in order to acquire such
shares.
 
    A member desiring to sell his or her Common Stock or Preferred Stock must
first offer them to the Company for purchase at par value. If the Company
declines to purchase such shares, either class may be sold to a new member
(i.e., another farm operator not already a member) and Preferred Stock may be
sold to one or more existing members or farm operators approved for membership,
in each case subject to approval by the Board of Directors. To date, the
Company's Board of Directors has not exercised the Company's right of first
refusal to purchase shares offered for sale by its members. In the absence of
the exercise of such right of first refusal, the Company is aware of sales of
Preferred Stock at prices in excess of the par value of those shares. However,
as the Company does not require parties seeking approval for transfers to
provide information regarding the transfer price, the Company does not possess
verifiable information regarding the transfer price involved in recent transfers
of the Company's Preferred Stock.

(1) During 1994, the Company adopted Statement of Financial Accounting Standards
    No. 106, "Employers' Accounting for Post-Retirement Benefits Other than
    Pensions" and Financial Accounting Standards No. 112, "Employers Accounting
    for Post-Employment Benefits." The cumulative effect of application of the
    new standards resulted in the reduction of net proceeds shown above for the
    year ended August, 1994. See note number 8 to the Financial Statements for
    the fiscal year ended August 31, 1996, for a more detailed description of
    the accounting change.
 
(2) Net Proceeds are the Company's gross revenues, less the costs and expenses
    of producing and marketing sugar, by-products and beet seed, but before
    payments to members for sugarbeets. Payments to be made to members for the
    delivery of sugarbeets are liabilities of the Company. (For a more complete
    description of the calculation of Net Proceeds, see "Description of Business
    Growers' Contracts.")
 
(3) Calculated by dividing the Company's long term debt, exclusive of the
    current maturities of such debt, by members' investments.
 
(4) Computed by dividing (i) the sum of Net Proceeds plus interest plus
    depreciation by (ii) the sum of interest plus principal payments. Although
    the Company does lease certain items, such as some office furniture, office
    equipment and computers, due to the proportionately small amounts involved,
    such lease payments have not been included in the total of the Company's
    Fixed Charges or the calculation of this ratio.
 
(5) Information for a fiscal year relates to the crop planted and harvested in
    the preceding calendar year (e.g., information for the fiscal year ended
    August 31, 1998 relates to the crop of 1997).

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
  RESULTS OF OPERATIONS:
 
    THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITIONS AND RESULTS OF
OPERATIONS OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH THE COMPANY'S
FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED ELSEWHERE IN THIS REPORT.
 
FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS
 
    This Report contains forward-looking statements regarding, among other
items, the Company's growth strategy and anticipated trends in the Company's
business. These forward-looking statements are based largely on the Company's
expectations and are identified by the use of words such as "believes",
"intends", and "will", subject to a number of risks and uncertainties, certain
of which are beyond the Company's control. Actual results could differ
materially from these forward-looking statements as a result of the factors
described elsewhere herein, including, among others, weather, regulatory or
economic influences. In light of these risks and uncertainties, there can be no
assurance that the forward-looking information contained in this Report will in
fact transpire or prove to be accurate.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Because American Crystal operates as a cooperative, payments for member
delivered sugarbeets, the principal raw material used in producing the sugar and
agri-products it sells, are subordinated to all member business expenses. In
addition, actual cash payments to members are spread over a period of
approximately one year following delivery of their sugarbeet crops to American
Crystal and are net of unit retains allocated to them, both of which remain
available to meet American Crystal's capital requirements. This member financing
arrangement may result in an additional source of liquidity and reduced outside
financing requirements in comparison to a similar business operated on a
non-cooperative basis. However, because sugar is sold throughout the year (while
sugarbeets are processed primarily in the fall and winter) and because
substantial amounts of equipment are required for its operations, American
Crystal has utilized substantial outside financing on both a seasonal and
long-term basis to fund such operations. The majority of such financing has been
provided by the St. Paul Bank for Cooperatives (the "Bank"). American Crystal
has a long-term debt commitment with the Bank in 1998 of $191.2 million. In
addition, American Crystal has long-term debt outstanding of $50 million in a
private placement. The Company also has a seasonal line of credit with the Bank
of $280 million, including any amounts obtained through issuance of instruments
in its commercial paper program. American Crystal also has a line of credit with
Norwest Bank for $10 million. The Company also utilizes a commercial paper
program, which provides short-term borrowings of up to $150 million.
 
RESULTS OF OPERATIONS
 
    INDUSTRY ENVIRONMENT
 
    The US sweetener industry experienced three significant trends during the
1970s and 1980s: increased consumption of non-nutritive sweeteners, principally
aspartame; the increased use of high fructose corn syrup (HFCS) as a substitute
for refined sugar (sucrose) in certain food products, primarily beverages; and a
significant degree of sugar industry consolidation.
 
    US sugar consumption has continued to expand over the past decade, with
domestic demand increasing from 153 million hundredweights in 1988 to 183
million in 1998. Although consumption growth rates have slowed to less than 1.5%
over the past two years, growth rates averaged close to 2.5% annually from 1990
to 1996. Sugar consumption growth rates are a function of population growth,
which has increased slightly over the past five years, and food market trends.
The non-fat and low-fat food trend of the early and mid-1990s resulted in
increased sugar use due to replacement of sucrose for fat in processed foods.
Currently, slowdowns in the non-fat and low-fat food product area contributed in
part to an overall
 
                                       15
<PAGE>
decline in sugar consumption growth rates. Despite this slowdown, the Company
believes that sugar consumption should continue to trend upward over time.
 
    Consumption of corn sweeteners is projected to grow at an annual rate of 4
to 5% over the next five years. Food manufacturers continue to increase research
and development budgets to expand use of corn and alternative sweeteners in
products.
 
    The Company's operational results are substantially dependent on market
factors, including domestic prices for refined sugar. These factors are
continuously influenced by a wide variety of market forces, including domestic
sugarbeet and cane production, weather conditions and United States farm and
trade policy, that the Company is unable to predict (see "Business Government
Programs and Regulations"). In addition, highly variable weather conditions
during the growing, harvesting and processing seasons, as well as diseases and
insects, may materially affect the quality and quantity of sugarbeets available
for purchase as well as the unit costs of raw materials and processing. Sugar
prices were at a premium during 1995 and 1996 due to shortages of domestic
sugarbeet production and less than adequate cane refinery capacity to cover this
shortfall. Refined pricing declined to more average levels during 1997 and 1998
due to increased sugar supplies and a softening demand outlook.
 
COMPARISON OF THE YEARS ENDED AUGUST 31, 1998 AND 1997
 
    Revenue for the year ended August 31, 1998, was $677 million, virtually the
same as in 1997. Revenue from total sugar sales increased 1.8%, reflecting a
5.6% increase in hundredweight sold, offset by a 3.7% decrease in the average
selling price per hundredweight. Revenue from pulp sales decreased 18.3% due to
a 25.1% decrease in the average selling price per ton, partially offset by a
9.1% increase in the volume of pulp sold. Revenue from molasses sales decreased
14.3% due to a 1.4% decrease in the volume of molasses sold and a 13.1% decrease
in the average selling price per ton. Revenue from concentrated separated by-
product (CSB) decreased 8.5% due to a 1.3% decrease in the volume of CSB sold
and a 7.4% decrease in the average selling price per ton.
 
    Cost of product sold, exclusive of payments to members for sugarbeets,
increased $64.8 million. This was primarily due to an increase in inventories
during 1997, which decreased the cost of product sold in 1997 by $62.1 million.
Direct costs increased by 3.2% due to higher freight and chemical costs. The
cost associated with purchased sugar decreased $.8 million in 1998 compared to
1997, when the short supply of inventory at the beginning of the fiscal year
created a greater need to purchase sugar to meet customer requirements. Fixed
and committed expenses increased by 6.4% due to higher depreciation and higher
storage costs.
 
    Selling expenses increased $11.5 million. The increase is attributable
primarily to the increase in the marketing and packaging costs. General and
Administrative expenses were approximately the same as 1997.
 
    Interest expense decreased from $18.3 million during the year ended August
31, 1997, to $14.4 million for the same period in 1998. This resulted from an
increase in pollution control bond interest income, bank patronage income along
with an increase in interest charged to United Sugars Corporation for the
marketing assets.
 
    Non-member business activities resulted in a loss of $9.7 million for the
year ended August 31, 1998, as compared to a loss of $18.1 million for the same
period in 1997. The majority of this loss is related to American Crystal's
investment in ProGold Limited Liability Company.
 
    Payments to members for sugarbeets decreased by $61.3 million from $368.2
million during the year ended August 31, 1997 to $306.9 million during the same
period in 1998. The decrease is attributable primarily to a lower per-ton beet
payment for the current fiscal year.
 
                                       16
<PAGE>
    As of August 31, 1998, American Crystal has made extensive efforts to become
Year 2000 compliant. Eighteen months ago, a new computer software package (SAP)
was installed which made most of the company-wide computer systems and its
hardware compliant for the Year 2000. This includes software for the financial
applications such as accounts payable, accounts receivable and general ledger as
well as costing, project accounting, sales and distribution, plant maintenance,
and production planning. The payroll and human resources software has also been
upgraded to be Year 2000 compliant and will be running on hardware that is
compliant by the end of 1998.
 
    Work has also been done at the factories to ensure the systems and controls
used in the day-to-day production of sugar will not be adversely effected by
Year 2000 problems.
 
    A Year 2000 Assessment Team has been formed with representation from various
locations and departments, information services functions as well as two of
American Crystal's associated companies, United Sugars Corporation and Midwest
Agri-Commodities Company. This committee is in the process of assessing what
additional systems the Company uses and if there are any Year 2000 compliance
problems. The systems that are determined to be non-compliant will then be
examined, risk assessed and action will be taken as deemed appropriate and
necessary.
 
    Year 2000 compliance may also adversely affect the operations and financial
performance of the Company indirectly by causing complications of, or otherwise
affecting, the operations of any one or more of the Company's suppliers and
customers. The Company has begun contacting its significant suppliers and
customers as part of its Year 2000 compliance plan. The Company's goal is to
identify any potential year 2000 compliance issues with the enterprises with
whom the Company does business. Although the results of this effort indicate
that many of the Company's customers and suppliers will be year 2000 compliant,
the Company is currently unable to predict the magnitude of the operational and
financial impact on the Company of year 2000 compliance issues with the
Company's suppliers and customers.
 
    The Company expects to incur (and expense) up to $60,000 during the fiscal
year which began on September 1, 1998 to resolve the remaining year 2000
compliance issues. The Company also expects to incur up to $20,000 during that
fiscal year for new software and hardware; those amounts will be capitalized.
 
COMPARISON OF THE YEAR ENDED AUGUST 31, 1997 AND 1996
 
    Revenue for the year ended August 31, 1997, was $677 million, a decrease of
$11 million from the same period in 1996. Revenue from total sugar sales
decreased 1.8% reflecting a 7.2% decrease in hundredweight sold and a 5.9%
increase in the average selling price per hundredweight. Revenue from pulp sales
increased 5.1% due to a 2.9% increase in the volume of pulp sold and a 2.1%
increase in the average selling price per ton. Revenue from molasses sales
decreased 11.5% due to a 12.3% decrease in the volume of molasses sold partially
offset by a .9% increase in the average selling price per ton. Revenue from
concentrated separated by-product (CSB) increased 21.2% due to a 10.3% decrease
in the volume of CSB sold and a 35.5% increase in the average selling price per
ton.
 
    Cost of product sold, exclusive of payments to members for sugarbeets,
decreased $79.9 million. The decrease was primarily due to the amount of
products sold compared to the prior year which was partially offset by increased
direct processing costs. Changes in product inventory levels decreased the cost
of product sold by $103 million. The cost associated with sugar purchased to
meet customer needs was up $1.1 million due to the short supply of inventory at
the beginning of the fiscal year. Fixed and committed expenses increased by 4.7%
due to higher depreciation costs.
 
    Selling expenses decreased $10.5 million. The decrease is attributable
primarily to the decrease in the volume of sugar and by-products sold. General
and Administrative expenses decreased $2.7 million due primarily to lower
outside services and other general cost decreases.
 
                                       17
<PAGE>
    Interest expense increased $7.1 million from $11.2 million during the year
ended August 31, 1996, to $18.3 million for the same period in 1997. This
resulted from higher average borrowing levels for long and short-term debt.
 
    Non-member business activities resulted in a loss of $18.1 million for the
year ended August 31, 1997 as compared to a loss of $396,000 for the same period
in 1996. The majority of this loss is related to American Crystal's investment
in ProGold Limited Liability Company.
 
    Payments to members for sugarbeets increased by $73.6 million from $294.6
million during the year ending August 31, 1996 to $368.2 million during the same
period in 1997. The increase is attributable to an increase in the sales price
for the Company's products, a reduction in the Company's expenses and additional
tons harvested.
 
COMPARISON OF THE YEARS ENDED AUGUST 31, 1996, AND 1995
 
    Revenue for the year ended August 31, 1996, was $688.0 million, an increase
of $82.0 million from 1995. Revenue from total sugar sales increased 15.4%,
reflecting a 12.6% increase in hundredweight sold and a 2.5% increase in the
average selling price per hundredweight. Revenue from pulp sales decreased 7.5%,
due to a 16.9% decrease in the volume of pulp sold partially offset by an 11.3%
increase in the average selling price per ton. Revenue from molasses sales
increased 32.4%, due to a 29.0% increase in the volume of molasses sold and a
2.6% increase in the average selling price per ton. Revenue from concentrated
separated by-products (CSB) increased 4.6%, due to a 2.4% increase in the volume
of CSB sold and a 2.2% increase in the average selling price per ton. Revenue
from beet seed sales was down 4.5%, primarily due to decreased sales volume
offset by an increase in sales prices.
 
    Cost of product sold, exclusive of payments to members for sugarbeets,
increased $72.5 million. The increase was primarily due to changes in product
inventory levels between 1996 and 1995, which impacted the cost of product sold
unfavorably by $77.1 million. Direct processing costs for sugar and pulp
decreased 2.5% primarily due to the harvesting and processing of a 3.6% smaller
crop. Fixed and committed expenses decreased by 2.9% due to a shorter processing
campaign.
 
    Selling expenses increased $17.9 million. The increase was attributable
primarily to increased sales volume. General and administrative expenses
increased $4.5 million due primarily to higher information services costs,
capital projects expense and general increases in personnel costs, partially
offset by a favorable settlement of an IRS tax case.
 
    Interest expense decreased $3.2 million from $14.5 million in 1995, to $11.3
million in 1996. This resulted from lower 1996 average interest rates for both
long-term and short-term debt, partially offset by higher average borrowing
levels.
 
    Non-member business activities resulted in a loss of $396,000 in 1996 and a
loss of $15,000 in 1995.
 
    Unit retains of $16.0 million and $16.6 million were withheld from members
in 1996 and 1995, respectively. The unit retain per-ton-purchased was $2.00 in
1996 and 1995.
 
    Payments to members for sugarbeets decreased by $14.9 million from $309.5
million in 1995 to $294.6 million in 1996. The decrease is attributable
primarily to a decrease in tons harvested and a lower average sugar content from
the 1995 crop of sugarbeets.
 
1998 CROP AND ESTIMATED FISCAL YEAR 1999 INFORMATION
 
    As noted earlier, the agreements between the Company and its members
regarding the delivery of sugarbeets to the Company require payment for members'
sugarbeets in three installments throughout the year after harvest of the
applicable sugarbeet crop. As only the final payment is made after the close of
the fiscal year in question, the first two payments to members for their
sugarbeets are, of necessity, based upon the Company's then-current estimates of
the Net Beet Payment arising from the processing of the crop in
 
                                       18
<PAGE>
question and the subsequent sale of the products obtained from processing those
sugarbeets. This discussion contains a summary of the Company's current
estimates of the financial results to be obtained from the Company's processing
of the 1998 sugarbeet crop. Given the nature of the estimates required in
connection with the payments to members for their sugarbeets, this discussion
includes forward-looking statements regarding the quantity of sugar to be
produced from the 1998 sugarbeet crop, the net selling price for the sugar and
agri-products produced by the Company and the Company's operating costs. These
forward-looking statements are based largely upon the Company's expectations and
estimates of future events; as a result, they are subject to a variety of risks
and uncertainties. Some of those estimates, such as the selling price for the
Company's products and the quantity of sugar produced from the sugarbeet crop,
are beyond the Company's control. The actual results experienced by the Company
could differ materially from the forward-looking statements contained herein. As
indicated above, the Company will prepare new, then-current estimates in
connection with the payment to the members of the second installment of the Net
Beet Payment. (That installment is expected to be made to the members with
respect to the 1998 sugarbeet crop on or about March 31, 1999.)
 
    The completed harvest of the sugarbeet crop grown during 1998 produced a
total of 10.7 million tons of sugarbeets, or approximately 22.2 tons of
sugarbeets per acre from approximately 481,000 acres. That production exceeded
16.8 tons per acre, which is the ten-year average of tons per acre for the years
1988 through 1997. The sugar content of the 1998 crop is 17.66% in comparison to
a ten year average for the applicable period of approximately 17.36%. The
Company expects to produce a total of approximately 27.0 million hundredweight
of sugar from the 1998 crop, representing an estimated increase of 5.3 million
hundredweight of sugar in comparison to the 1997 crop. Such sugar production
provides a total sugar recovery of approximately 256 pounds of sugar for each
ton of sugarbeets harvested by the Company.
 
    The Company's anticipated recovery of sugar from each ton of sugarbeets
results in expected sugar revenue per ton of sugarbeets in an amount equal to
$58.76 per ton.
 
    The Company's sales of sugar must be added to the revenue produced by the
agri-products: molasses, beet pulp and concentrated separated by-product to
determine the net beet payment. The Company's estimates of additional revenue
from those sources would be $3.28 per ton of sugarbeets.
 
    From the revenues generated from the sale of products produced from each ton
of sugarbeets must be deducted the Company's operating costs, which are
currently estimated to be $23.74 per ton. The deduction of those operating costs
results in an estimated gross beet payment of $38.50 per ton of sugarbeets. With
the deduction of an anticipated unit retain of $2.00 per ton for the fiscal year
ending on August 31, 1999, the Company's current estimated Net Beet Payment is
$36.50 per ton of sugarbeets. If successful in achieving the estimated results,
the Company's Net Beet Payment will be lower than the ten year average Net Beet
Payment by approximately $3.74 per ton.
 
THE COMPANY'S CURRENT STRATEGIC PLAN
 
    In order to obtain the best selling price for its products, the Company
intends to focus on sales and marketing strategies which allow the Company to
provide its customers with an appropriate mixture of the Company's products. The
Company is optimizing its customer mix, improving logistics and continually
trying to evaluate and improve its customer performance.
 
    To pursue the goal of maintaining and improving upon its current status as a
low cost producer, the Company intends to focus on working with its members to
increase the productivity of the members' sugarbeet farming operations. In
addition, the Company plans to focus on cost reduction at the factory level. At
the member level, the Company expects to focus on, among others, programs for
nitrogen management and new seed varieties. At the factory level, the Company
intends to pursue on-going maintenance and improvements. The Company is part of
the Crystech joint venture to construct and operate a molasses desugarization
plant at the Company's Hillsboro plant, which would allow the Company to desugar
the balance of its molasses to extract additional sugar. Currently,
approximately one-
 
                                       19

half of the Company's molasses is desugared. The Company's goal in participating
in the molasses desugarization plant is to reduce the Company's average cost of
sugar production, through the use of current separation technologies.

    executive under the Company's LTIP plan (described below) during the fiscal
    year and (ii) "profit per acre payments" made to the executive under the
    Company's LTIP plan. The profit per acre payments are determined by
    subtracting from the Company's beet payment per acre the average cost of
    production per acre incurred by the Company's members and multiplying the
    result by the number of contract rights held by the executive.
 
(4) Mr. Richardson also served as interim Chief Executive Officer between June
    1995 and March 1996.
 
    Effective May 15, 1998, the Company and Mr. Horvath entered into an
"Employment Agreement" regarding Mr. Horvath's employment by the Company. The
agreement provides that Mr. Horvath shall serve as an "at will" employee at the
pleasure of the Board of Directors. Among other terms, the agreement establishes
Mr. Horvath's base compensation at $388,840 per year, and also provides that he
may participate in other benefit plans offered by the Company. If the Board of
Directors terminates Mr. Horvath's employment with the Company without cause
after age 60 or he incurs a termination due to disability, Mr. Horvath is
entitled to receive reimbursement for the cost of medical and dental coverage
for himself and his spouse from the date of termination through their respective
deaths; life insurance
 
                                       26

coverage to age 59 1/2 equal to his base salary on the date of termination, from
age 65 to 70 equal to 50% of his base salary on the date of termination, and
after age 70 equal to 25% of his base salary on the date of termination; and
supplemental pension benefits equal to the difference between the cumulative
monthly amount of the retirement benefit Mr. Horvath would have received under
Retirement Plan A and the Supplemental Executive Retirement Plan (SERP) computed
as though Mr. Horvath continued his employment to age 65 and had attained 30
years of service, and the cumulative monthly amount of the retirement benefits
actually paid to Mr. Horvath under Retirement Plan A and the Supplemental
Executive Retirement Plan (SERP). If the Board of Directors terminates Mr.
Horvath's employment with the Company without cause before age 55 or he incurs a
termination due to disability, Mr. Horvath is entitled to receive supplemental
early retirement benefits equal to the difference between the cumulative monthly
amount of the retirement benefit Mr. Horvath would have received under
Retirement Plan A and the Supplemental Executive Retirement Plan (SERP) computed
as though Mr. Horvath continued his employment to age 55 and assuming
compensation equal to that in effect as of the termination date with no
reduction in benefits for death benefits payable to Mr. Horvath's spouse, and
the cumulative monthly amount of the retirement benefits actually paid to Mr.
Horvath under Retirement Plan A and the Supplemental Executive Retirement Plan
(SERP) assuming commencement at age 55. If the Board of Directors terminates Mr.
Horvath's employment with the Company without cause after age 60 and Mr. Horvath
subsequently dies, or if Mr. Horvath dies prior to terminating his employment
with the Company, Mr. Horvath's spouse is entitled to receive monthly payments
for the remainder of her life equal to the difference between the cumulative
monthly amount of the retirement benefit Mr. Horvath would have received under
Retirement Plan A and the Supplemental Executive Retirement Plan (SERP) computed
as though Mr. Horvath continued his employment to age 65 and had attained 30
years of service, and the cumulative monthly amount of the retirement benefits
actually payable to his spouse under Retirement Plan A and the Supplemental
Executive Retirement Plan (SERP). The agreement also contains the provision of a
three-year non-compete/non-solicitation agreement with Mr. Horvath.
 
    Certain management employees are entitled to participate in an incentive
program that provides for cash awards based partially on the performance of the
Company and partially on achievement of certain management performance
objectives. Those performance objectives are determined by the Board of
Directors. An executive is not eligible for any awards under the incentive
program unless that executive's performance for the applicable fiscal year is
rated as "fully satisfactory" or better. Depending on the executive's
responsibilities, the performance of the Company (measured in terms of revenues
returned to the members) and the results of the executive's evaluation for the
fiscal year, the program provides for an incentive bonus in amounts ranging from
4% to 40% of the eligible executive's base salary.
 
    The Company has also adopted a Long Term Incentive Plan ("LTIP") which
provides deferred compensation to certain key executives of American Crystal
effective September 1, 1995. The LTIP creates financial incentives that reward
executives for long-term commitment to the Company and for successfully
implementing the Company's long-term growth strategies. Such incentives are
based upon contract rights which are available to the executive under the terms
of the LTIP, the value of which is related to the value of preferred shares of
the Company. The LTIP allows participants to purchase a limited number of
contract rights at the end of each three-year cycle. The LTIP establishes both
minimum and maximum ownership levels. When an executive reaches his minimum
ownership level, he or she may sell any vested shares over the minimum to any
qualified grower. The executive or his estate may also sell any vested shares at
the time of his termination, disability or death. At the point of sale, the
contract right becomes a share of Preferred Stock which the Company issues to
the purchasing grower. The executive receives the proceeds of the sale, less
appropriate taxes. The long-term cost of the stock will not be to the Company,
but to the grower who eventually purchases the stock from the executive. The
LTIP also provides for annual payments of "profit per acre payments" to
executives holding contract rights. The profit per acre payments are determined
by subtracting from the Company's beet payment per acre the average cost of
production per acre incurred by the Company's members and multiplying the result
by the number of contract rights held by the executive.
 
                                       27

    A total of 389 contract rights have been granted under the plan. As of the
date hereof, those executives listed above have been granted and hold contract
rights with respect to number of shares set forth below. Each contract right
listed below carried a stated value upon grant of $1,485 per share; the current
stated value is $1,500 per share.

(1) The amount shown represents a representative amount, determined for the last
    fiscal year, with respect to "profit per acre payments", which are non-stock
    price based payments. The profit per acre payments are determined by
    subtracting from the Company's beet payment per acre the average cost of
    production per acre incurred by the Company's members and multiplying the
    result by the number of contract rights held by the executive. Based on that
    formula, the Company must provide a beet payment per acre to its members
    equal to the average cost of production for an acre of sugarbeets in order
    for executives holding contract rights to obtain any payment of profit per
    acre payments. Given the method of determining the profit per acre payments,
    there is no maximum payment amount.
 
    To date, only Mr. McCarty has exercised his contract rights, having sold 155
contract rights in May, 1998.

    Management employees are also eligible to participate in the Company's
Retirement Plan "A," a 401(k) savings plan and, beginning on September 1, 1994,
a "Supplemental Executive Plan." Those plans are described below.
 
RETIREMENT PLANS
 
    The Company has established noncontributory, defined benefit retirement
plans which are available to all eligible employees of the Company. Those
employees who are covered by a collective bargaining agreement participate in
one plan, while employees who are not subject to a collective bargaining
agreement, including the executive officers listed on the Summary Compensation
Table, participate in another pension plan. That plan is known as Retirement
Plan "A." The benefits of the plan are funded by periodic Company contributions
to a retirement trust which invests the Company's contributions and the earnings
from such contributions in order to pay the benefits to the employees. The plan
provides for the payment of monthly retirement benefits determined under a
calculation based on years of service and a participant's compensation.
Retirement benefits are paid to participants upon normal retirement at the age
 
                                       28
<PAGE>
of 65 or later or upon early retirement. The plan also provides for the payment
of certain disability and death benefits.
 
    The following table reflects the estimated annual benefits payable to a
fully-vested executive officer of the Company under Retirement Plan "A," upon
retirement at age 65, after 15, 20, 25, 30 and 35 years of annual service at the
remuneration levels set forth in the table:

    The five executive officers named in the Summary Compensation Table who are
currently employees of the Company, have years of service under the plan as
follows: Mr. Horvath has served for 13 years; Mr. Richardson has served for 18
years; Mr. Dudley has served for 14 years; Mr. Levos has served for 33 years;
and Mr. Mathias has served for 22 years.
 
    The Company maintains a Section 401(k) plan that permits employees to elect
to set aside, on a pre-tax basis, a portion of their gross compensation in trust
to pay future retirement benefits. The Company matches 100% of the employee's
first 4% of compensation. The total annual pre-income tax addition to any
employees' account in any calendar year may not exceed the lesser of (i) $30,000
or (ii) 25% of annual compensation less the amount of the contribution and any
salary conversion. During 1998, the employee pre-income tax contribution was
limited to $10,000. An employee may also contribute up to 10% of his annual
compensation on an after-tax basis. Benefits under the 401(k) plan begin to be
paid to the employee upon the close of the plan year in which one of the
following events has occurred: the date the employee attains age 59 1/2 , the
date the employee terminates his service with the employer and the date
specified in a written election made by the employee to receive benefits no
later than April 1 of the year following the calendar year in which the employee
retires, dies, becomes disabled, reaches age 70 1/2 or is terminated.
 
    Effective September 1, 1994, certain executive employees of the Company
became eligible to participate in a "Supplemental Executive Retirement Plan."
That plan was adopted by the Company's Board of Directors on June 30, 1994.
Subject to the discretion of the Board of Directors, the plan provides for the
Company to credit to the account of each executive eligible to participate in
the Supplemental Plan amounts equal to (i) the difference between amounts
actually contributed to the Company's 401(k) plan on behalf of the executive and
the amounts which could have been contributed if certain provisions of the
Internal Revenue Code did not prohibit the contribution of such amounts and (ii)
the difference between the benefits actually payable to the executive under the
provisions of Retirement Plan "A" and the amounts which would be payable under
Retirement Plan "A" if certain provisions of the Internal Revenue Code did not
prohibit the payment of such benefits. In addition, the executive may elect to
defer a portion of his or her compensation, ranging from 2% to 16%, by regular
payroll deductions under the Supplemental Plan,
 
                                       29
<PAGE>
and may also defer 100% of all bonus and profits-per-acre payments. The
Supplemental Plan is an "unfunded" plan, with all amounts to be paid under the
Supplemental Plan to be paid from the general assets of the Company when due and
also to be subject to the claims of the Company's creditors.
 
    The following table reflects the estimated annual benefits payable to a
fully-vested executive officer of the Company under the Supplemental Plan, upon
retirement at age 65, after 15, 20, 25, 30 and 35 years of annual service at the
remuneration levels set forth in the table:

ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
    As of the date hereof, no director owns beneficially more than 1% of the
Company's issued and outstanding Preferred Stock and the directors, as a group,
beneficially own less than 3% of the Company's issued and outstanding Preferred
Stock. To the best of the Company's knowledge, no other party beneficially owns
more than 1% of the Company's Preferred Stock.
 
ITEM 13.  CERTAIN RELATIONSHIPS RELATED TRANSACTIONS
 
    Each of the Company's directors is also a sugarbeet farmer and a shareholder
member or representative of a shareholder member of American Crystal. By virtue
of their status as such members of the Company, each director or the member he
represents sells sugarbeets to the Company and receives payments for those
sugarbeets. Such payments for sugarbeets often exceed $60,000. However, such
payments are received by the directors or the entities they represent on exactly
the same basis as payments are received by other members of the Company for the
delivery of their sugarbeets. Except for the sugarbeet sales described in the
preceding sentences, none of the directors or executive officers of the Company
have engaged in any other transactions with the Company involving amounts in
excess of $60,000.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Members of American Crystal Sugar Company
Moorhead, Minnesota
 
    We have audited the accompanying balance sheets of the American Crystal
Sugar Company (a Minnesota cooperative corporation) as of August 31, 1998 and
1997, and the related statements of operations, changes in members' investments
and cash flows for the years ended August 31, 1998, 1997 and 1996. These
financial statements are the responsibility of the company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the American Crystal Sugar
Company as of August 31, 1998 and 1997, and the results of its operations and
its cash flows for the years ended August 31, 1998, 1997 and 1996, in conformity
with generally accepted accounting principles.

                         AMERICAN CRYSTAL SUGAR COMPANY
 
                       NOTES TO THE FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    ORGANIZATION
 
    American Crystal Sugar Company (American Crystal or Company) is a Minnesota
agricultural cooperative corporation which processes and markets sugar,
sugarbeet pulp, molasses and seed. Business done with its shareholders (members)
constitutes "patronage business" as defined by the Internal Revenue Code, and
the net proceeds therefrom are credited to members' investments in the form of
unit retains or distributed to members in the form of payments for sugarbeets.
Members are paid the net amounts realized from the current year's production
less member operating costs determined in conformity with generally accepted
accounting principles.
 
    CASH AND CASH EQUIVALENTS
 
    American Crystal considers financial instruments purchased with a maturity
of three months or less to be cash equivalents. American Crystal places its
temporary cash investments with high credit quality financial institutions. At
times, such investments may be in excess of the applicable insurance limit.
 
    RECEIVABLES
 
    American Crystal grants credit, individually and through its marketing
cooperatives, to its customers, which are primarily companies in the food
processing industry located throughout the United States. Ongoing credit
evaluations of customers' financial condition are performed and the Company
maintains a reserve for potential credit losses. The Company has a major
customer that accounted for approximately 10 percent of gross sugar sales for
the year ended August 31, 1998. Accounts receivable from this customer totaled
approximately 12 percent of total receivables as of August 31, 1998.
 
    INVENTORIES
 
    Sugar, pulp, molasses and other agri-products inventories are valued at
estimated net realizable value. Maintenance parts and supplies and beet seed
inventories are valued at the lower of average cost or market.
 
    PROPERTY, EQUIPMENT AND DEPRECIATION
 
    Property and equipment are recorded at cost. Indirect costs and construction
period interest are capitalized as a component of the cost of qualified assets.
Property and equipment are depreciated for financial reporting purposes
principally using straight-line and declining-balance methods with estimated
useful lives ranging from 3 to 45 years. Statutory lives and methods are used
for income tax reporting purposes.
 
    Indirect costs capitalized were $1.3 million, $1.1 million and $1.0 million
in 1998, 1997 and 1996, respectively. Construction period interest capitalized
was $3.9 million, $2.6 million and $3.8 million in 1998, 1997 and 1996,
respectively.
 
    INVESTMENTS
 
    Investments in the Banks for Cooperatives are stated at cost plus unredeemed
patronage refunds received in the form of capital stock. Investments in
marketing cooperatives, ProGold Limited Liability Company (ProGold) and
Crystech, LLC (Crystech) are accounted for using the equity method. The net

capitalized interest related to the investment in ProGold totaled $1.1 million
and $3.1 million for the years ended August 31, 1997 and 1996, respectively. The
net capitalized interest in Crystech totaled $29,000 for the year ended August
31, 1998.
 
    MEMBERS' INVESTMENTS
 
    PREFERRED AND COMMON STOCK--The ownership of common and preferred stock is
restricted to a "farm operator" as defined by the bylaws of American Crystal.
Each "farm operator" may own only one share of common stock and is entitled to
one vote in the affairs of American Crystal. Each "farm operator" is entitled to
grow a specified number of acres of sugarbeets in proportion to the shares of
preferred stock owned. The preferred shares are non-voting. All transfers of
stock must be approved by American Crystal's board of directors and any
shareholder desiring to sell stock must first offer it to American Crystal for
repurchase at its par value. American Crystal has never exercised this
repurchase option. The bylaws do not allow dividends to be paid on either the
common or preferred stock.

</TABLE>
 
    UNIT RETAINS--The bylaws authorize American Crystal's board of directors to
require additional direct capital investments by members in the form of a
variable unit retain per ton of up to a maximum of 10% of the weighted average
gross per ton beet payment. American Crystal has a policy whereby the Company
refunds, to the entity legally entitled thereto, the unit retains attributable
to a deceased or totally and permanently disabled former shareholder.
 
    RETAINED EARNINGS--Retained earnings represent the cumulative net
income/(loss) resulting from non-member business and the difference between
member income as determined for financial reporting purposes and federal income
tax reporting purposes from the years prior to 1996. The non-member net loss was
$9.7 million, $18.1 million and $.4 million in 1998, 1997 and 1996,
respectively.
 
    STOCK OFFERING
 
    On July 23, 1997, the Board of Directors authorized an offer of up to 61,500
shares of Preferred Stock, $76.77 par value and up to 500 shares of Common
Stock, $10.00 par value for sale at $1,500.00 per share and $10.00 per share,
respectively, to sugarbeet farm operators in the territory in which the Company
is engaged in business. The filings with the Securities and Exchange Commission
and the North Dakota Securities Commission became effective in November, 1997.
The Company sold all of the 61,500 shares of preferred stock offered. The shares
of Preferred Stock offered equal approximately 13.7% of preferred shares
outstanding on July 25, 1997. The Company received approximately $56.0 million
from the sale of

stock during the year ended August 31, 1998, with the remaining installment
amounts to be received over the next six years.
 
    INTEREST EXPENSE, NET
 
    American Crystal earns patronage dividends from the Banks for Cooperatives
based on American Crystal's share of the net income earned by the banks. These
patronage dividends are applied against interest expense.
 
    INCOME TAXES
 
    American Crystal is a non-exempt cooperative for federal income tax
purposes. As such, American Crystal is subject to corporate income taxes on its
net income from non-member sources. The provision for income taxes relates to
the results of operations from non-member business, state income taxes and
certain other permanent differences between financial and income tax reporting.
Total income tax payments (refunds) were $106,000, $(4,000) and $(139,000), in
the years ended August 31, 1998, 1997 and 1996, respectively.
 
    As of August 31, 1998, American Crystal had accumulated approximately $29.0
million of net operating loss carryforwards. The majority of the net operating
loss carryforwards expire in 2012. American Crystal has provided a valuation
allowance for the entire balance of the deferred tax asset related to the loss
carryforwards.
 
    ACCOUNTING ESTIMATES
 
    The preparation of the financial statements in conformity with generally
accepted accounting principals requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
    RECLASSIFICATIONS
 
    Certain reclassifications have been made to the 1997 and 1996 financial
statements to conform with the 1998 financial statement presentation.
 
(2) INVENTORIES:
 
    The major components of inventories are as follows:

(5) CRYSTECH, LLC:
 
    On May 28, 1998, the Company entered into an agreement with Newcourt Capital
U.S.A., Inc. to form a joint venture (special purpose) entity, Crystech, LLC
(Crystech). Crystech was formed to acquire, construct, finance, operate and
maintain a molasses desugarization facility at the Company's Hillsboro, North
Dakota sugar factory together with certain sugar processing equipment located at
the Hillsboro, North Dakota and Moorhead, Minnesota sugar factories. The Company
acquired an initial 50% ownership interest in Crystech through a $1.5 million
cash contribution. The Company accounts for its investment in the joint venture
using the equity method.
 
    As of August 31, 1998, the Company had an outstanding note receivable from
Crystech totaling $3.7 million. The note is subordinate to long-term debt of
Crystech totaling $23.0 million as of August 31, 1998. The note bears interest
at the rate of 7.62%. Interest income related to this note totaled $70,000
during 1998. Equal quarterly payments of principal on the note begin at the
earlier of April 30, 2000, or provisional acceptance (when 90% of expected plant
performance is reached), but no later than October 31, 2000. American Crystal
has agreed to provide $13.9 million of subordinated debt to Crystech. Payments
are to be made each quarter in 28 installments of $496,607 for the subordinated
debt. Subsequent quarterly principal payments are due on the following dates
annually: March 1, June 1, September 1 and December 1. As of August 31, 1998,
the Company also had an outstanding receivable of $1.4 million relating to
expenses paid on behalf of Crystech.
 
    The Company has a 12-year tolling services agreement with Crystech whereby
upon completion of construction, the Company pays for tolling services for
processing beet molasses delivered to Crystech with title and risk of loss
throughout the process maintained by the Company. The tolling agreement may be
terminated by the Company if the specified plant performance is not achieved.

capital; ratio of term liabilities to members' investment; current ratio; level
of term debt to net funds generated; and investment in bank stock in amounts
prescribed by the bank. Substantially all non-current assets are pledged to the
senior lenders to provide security to support the Company's seasonal and
long-term financing. As of August 31, 1998, American Crystal was in compliance
with the terms of the loan agreements.
 
    Interest paid was $19.7 million, $21.6 million and $16.1 million for the

(7) FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
    The fair value of financial instruments is generally defined as the amount
at which the instrument could be exchanged in a current transaction between
willing parties, other than in a forced liquidation sale. Quoted market prices
are generally not available for the Company's financial instruments.
 
    Accordingly, fair values are based on judgments regarding anticipated cash
flows, future expected loss experience, current economic conditions, risk
characteristics of various financial instruments and other factors. These
estimates involve uncertainties and matters of judgment, and therefore, cannot
be determined with precision. Changes in assumptions could significantly affect
the estimates.
 
    LONG-TERM DEBT--Based upon current borrowing rates with similar maturities,
the fair value of the long-term debt approximates the carrying value.
 
    INVESTMENTS IN BANKS FOR COOPERATIVES, INVESTMENTS IN MARKETING
COOPERATIVES, INVESTMENT IN PROGOLD LIMITED LIABILITY COMPANY AND INVESTMENT IN
CRYSTECH, LLC--American Crystal believes it is not practical to estimate the
fair value of these investments without incurring excessive costs because there
is no established market for these securities and equity interest, and it is
inappropriate to estimate future cash flows which are largely dependent on
future earnings of these organizations.

(8) EMPLOYEE BENEFIT PLANS:
 
COMPANY-SPONSORED DEFINED BENEFIT PENSION PLANS
 
    Substantially all employees who meet eligibility requirements of age and
length of service are covered by a Company-sponsored retirement plan. Plan A
(non-union employees) and Plan B (union employees) are defined benefit,
non-contributory plans. The plans provide for vesting after 5 years of service
with benefits for early retirement, normal retirement and disability or death.
 
    The assets of the plans are held by a bank and trust company. American
Crystal's funding policy for Plan A is to contribute the normal cost of the plan
determined under the entry age normal actuarial cost method, plus amounts
necessary to amortize changes over 30 years. The funding policy for Plan B is to
contribute the minimum required amount determined under the frozen initial
liability actuarial cost method. The actuarial assumptions are shown below:

rights issued which were 100% vested.

plan which are available to substantially all American Crystal retirees.
American Crystal also has a medical plan that covers disabled employees who have
not attained retirement age. The costs of these plans are paid by the Company.

other post-retirement and postemployment benefit (OPEB) obligations are in the

The Pledgor represents, warrants and covenants to the Secured Parties that:

          (a)  The chief place of business and chief executive office of the 
     Pledgor and the office where the Pledgor keeps its records concerning 
     the Collateral (hereinafter, collectively called the "RECORDS") is 
     located at __________________________.

          (b)  The Pledgor is a cooperative corporation duly organized, 
     validly existing and in good standing under the laws of the State of 
     Minnesota and is duly qualified to do business and is in good standing 
     in all places where necessary in light of the business it conducts and 
     the Property it owns and intends to conduct and own and in light of the 
     transactions contemplated by this Agreement.  No filing, recording, 
     publishing or other act that has not been made or done is necessary or 
     desirable in connection with the existence or good standing of the 
     Pledgor or the conduct of its business.

          (c)  The Pledgor has the full power, authority and legal right to 
     execute, deliver and perform its obligations under this Agreement.  The 
     execution, delivery and performance by the Pledgor of this Agreement and 
     the consummation of the transactions contemplated hereby have been duly 
     authorized by all necessary corporate and 

                               PLEDGE AGREEMENT

                                    - 5 -

     shareholder action.  This Agreement has been duly executed and delivered 
     by the Pledgor, has not been amended or otherwise modified, is in full 
     force and effect and is the legal, valid and binding obligation of the 
     Pledgor, enforceable against the Pledgor in accordance with its terms, 
     except as such enforceability may be limited by (i) applicable 
     bankruptcy, insolvency, moratorium or other similar laws affecting the 
     enforcement of creditors' rights generally and (ii) general principles 
     of equity (regardless of whether enforcement thereof is sought in a 
     proceeding at law or in equity).  The Pledgor is not in default in the 
     performance of any covenant or obligation set forth in any indenture or 
     loan or credit agreement, agreement, lease or instrument to which it is 
     a party or by which its Properties may be bound or affected, which 
     default has, or could reasonably be expected to have, a material adverse 
     effect on the Pledgor or the ability of the Pledgor to fulfill its 
     obligations under this agreement.

          (d)  The execution, delivery and performance by the Pledgor of this 
     Agreement and the consummation of the transactions contemplated hereby 
     do not and will not (i) require any consent or approval of the board of 
     directors or any shareholder of the Pledgor or any other Person that has 
     not been duly obtained and each such consent or approval that has been 
     obtained is in full force and effect, (ii) violate any provision of the 
     certificate of incorporation or the by-laws of the Pledgor or any 
     Governmental Rule or Governmental Approval applicable to the Pledgor, 
     (iii) conflict with, result in a breach of or constitute a default under 
     the certificate of incorporation, by-laws or any resolution of the board 
     of directors of the Pledgor or any indenture or loan or credit agreement 
     or other agreement, lease or instrument to which the Pledgor is a party 
     or by which it or its Properties may be bound or affected or (iv) result 
     in, or require the creation or imposition of, any Lien upon or with 
     respect to any of the properties now owned or hereafter acquired by the 
     Pledgor (other than any shares acquired by the Pledgor as a result of a 
     consolidation or merger of the Company).  The Pledgor is not in 
     violation of any such Governmental Rule or Governmental Approval or such 
     certificate of incorporation or by-laws or in breach of or default under 
     any indenture, loan agreement or credit agreement or other material 
     agreement, lease or instrument referred to in clause (iii) above which 
     violation, breach or default has or could reasonably be expected to have 
     a material adverse effect on the Pledgor or the ability of the Pledgor 
     to fulfill its obligations under this Agreement.

          (e)  This Agreement creates in favor of the Collateral Agent for 
     the equal and ratable benefit of the Secured Parties, a legal, valid and 
     enforceable Lien on and security interest in all of the Collateral, 
     subject to no equal or prior Lien securing the payment and performance 
     of the Secured Obligations, and all filings and other actions necessary 
     or desirable to create, preserve, validate, perfect and protect such 
     Lien and the priority thereof have been duly made or taken.

          (f)  No Governmental Approval by, and no filing with, any 
     Governmental Body is required to be obtained by the Pledgor in 
     connection with this Agreement and the transactions contemplated hereby 
     (except for the filing of the financing statements in the jurisdictions 
     identified in Annex 2 hereto).

          (g)  The Pledgor is the sole legal and beneficial owner of the 
     Collateral in which it purports to grant a security interest pursuant to 
     Section 3 hereof, and no Lien exists or will exist upon the Collateral 
     at any time (and, with respect to the Collateral, no right or option to 
     acquire the same exists in favor of any other Person), except for the 
     pledge and security interest in favor of the Collateral Agent for the 
     benefit of the Secured Parties created or provided for herein, which 
     pledge and security interest constitute a valid and enforceable first 
     priority perfected pledge and security interest in and to all of the 
     Collateral.

          (h)  There is no action, suit or proceeding at law or in equity or 
     by or before any Governmental Body, arbitral tribunal or other body now 
     pending, or to the best knowledge of the Pledgor, threatened against or 
     affecting the Pledgor or any of its Property or the Collateral which has 
     or could reasonably be expected to have a material adverse effect on the 
     Pledgor or the ability of the Pledgor to fulfill its obligations under 
     this Agreement.

          (i)  The Pledgor has filed or caused to be filed all tax returns 
     that are required to be filed, and has paid all taxes shown to be due 
     and payable on said returns or on any assessments made against the 
     Pledgor or any of its Property and all other Taxes imposed on the 
     Pledgor by any Governmental Body (other than Taxes the payment of which 
     are not yet due or which are being contested in good faith and Taxes for 
     which the failure to so file or pay does not have and could not 
     reasonably be expected to have a material adverse effect on the Pledgor 
     or the ability of the Pledgor to fulfill its obligations under this 
     Agreement), and no tax Liens have been filed and no claims are being 
     asserted with respect to any such Taxes.

          (j)  The Pledgor has all right, title, interest in, to and under, 
     and is the record owner of, the Collateral in which it purports to grant 
     a security interest pursuant to Section 3 and no Lien exists or will 
     exist upon the Collateral at any time (and no right to acquire the same 
     exists in favor of any other Person), except for the pledge and security 
     interest in favor of the Collateral Agent for the benefit of the Secured 
     Parties created or provided for herein, which pledge and security 
     interest constitute a first priority perfected pledge and security 
     interest in and to all of the Collateral.

          (k)  The Membership Interests identified in Annex 1 hereto are, and 
     all other Membership Interests of the Company in which the Pledgor shall 
     hereafter grant a 

                               PLEDGE AGREEMENT

     security interest pursuant to Section 3 hereof will be, duly authorized, 
     validly existing, fully paid and non-assessable, and none of such 
     interests is or will be subject to any contractual restriction, or any 
     restriction under the Company LLC Agreement, upon the transfer of such 
     membership interests, including without limitation the admission of any 
     such transferee as a Member of the Company (except for such restriction 
     contained herein).

          Section 3.  THE PLEDGE  
As collateral security for the prompt payment in full when due (whether at 
stated maturity, by acceleration or otherwise) of the Secured Obligations, 
the Pledgor hereby pledges, assigns, hypothecates and transfers to the 
Collateral Agent for the equal and ratable benefit of the Secured Parties, 
and hereby grants to the Collateral Agent for the equal and ratable benefit 
of the Secured Parties a Lien on and security interest in, all of the

     moneys due but unpaid and to become due under or pursuant to the Company 
     LLC Agreement, (ii) all rights of the Pledgor to participate in the 
     operation or management of the Company and to take actions or consent to

     Agreement or consent to or accept any cancellation or termination 
     thereof, (ii) amend, supplement or otherwise modify the Company LLC 
     Agreement in a manner that would be adverse to the interests of the 
     Noteholders under the Financing Documents or adversely affect the rights 
     or remedies of the Collateral Agent hereunder or the value of the 
     Collateral or (iii) petition, request or take any other legal or

     the Secured Obligations pursuant to an assignment and assumption

          (b)  if any of the certificates, warrants, rights, options or other 
     Property required to be pledged by the Pledgor under Section 3 hereof 
     are received by the Pledgor, forthwith (i) transfer and deliver to the 
     Collateral Agent such certificates, warrants, rights, options or other 
     Property so received by the Pledgor (together with the certificates for 
     any such Membership Interests and securities duly endorsed in blank), 
     all of which thereafter shall be held by the Collateral Agent, pursuant 
     to the terms of this Agreement, as part of the Collateral and/or (ii) 
     take such other action as the Collateral Agent shall deem necessary or

     Majority Holders) to create, preserve, perfect or validate the security 
     interest granted pursuant hereto or to enable the Collateral Agent to 
     exercise and enforce its rights hereunder with respect to such pledge 
     and security interest  including, without limitation, causing any or all

     Collateral Agent to be present at the Pledgor's place of business to 
     receive copies of all communications and remittances relating to the 
     Collateral, all in such manner as the Collateral Agent may require, and 
     forward promptly to the Collateral Agent written copies of any notices 
     or communications received by the Pledgor with respect to the 
     Collateral; and

          (f)  if any of the Collateral shall be evidenced by a promissory note
     or other

     ratable benefit of the Secured Parties any all such notes or 
     instruments, endorsed and/or accompanied by such executed instruments of 
     assignment and transfer in such form and substance as the Collateral 
     Agent may reasonably request.

          5.02  OTHER FINANCING STATEMENTS AND LIENS.  
Without the prior consent of the Collateral Agent (which the Collateral Agent 
will provide to the extent directed to do so by the Majority Holders), the 
Pledgor shall not file or suffer to be on file, or authorize or permit to be 
filed or to be on file, in any jurisdiction, any financing statement, 
recordation of Liens or like instrument with respect to the Collateral in 
which the Collateral Agent is not named as the sole secured party for the 
benefit of the Secured Parties.

          5.03  PRESERVATION OF RIGHTS.  
The Collateral Agent shall not be required to take steps necessary to 
preserve any rights against prior parties to any of the Collateral.

          5.04  COLLATERAL.

and be continuing, the Pledgor shall have the right to exercise all voting, 
consensual and other powers of ownership pertaining to the Collateral for all 
purposes not inconsistent with the terms of this Agreement, the Note Purchase 
Agreement or any other Financing Document; and, the Collateral Agent shall 
execute and deliver to the Pledgor or cause to be executed and delivered to 
the Pledgor all such proxies, powers of attorney, dividend and other orders, 
and all such instruments, without recourse, as the Pledgor may reasonably 
request in a writing delivered to the Collateral Agent for the purpose of 
enabling the Pledgor to exercise the rights and powers which it is entitled 
to exercise pursuant to this Section 5.04(a).

          (b)  Unless and until a Default or Event of Default has occurred 
and is continuing, the Pledgor shall be entitled to receive, retain and 
distribute as dividends or otherwise any dividends on the Collateral paid or 
payable in accordance with the terms of the Agency and Disbursement Agreement.

          (c)  If any Default or Event of Default shall have occurred and be 
continuing, and whether or not the Collateral Agent or any other Secured 
Party exercises any available right to declare any Secured Obligation due and 
payable or seeks or pursues any other relief or remedy available to it under 
applicable law or under this Agreement, the Note Purchase Agreement or any 
other Financing Document, all dividends and other distributions on the 
Collateral received by the Pledgor in trust for the benefit of the Collateral 
Agent, shall be segregated from other funds of the Pledgor and shall be 
forthwith paid over to the Collateral Agent in the same form as 

                               PLEDGE AGREEMENT

                                    - 12 -

received.  Subject to the terms of this Agreement, and, if the Collateral 
Agent shall so request, the Pledgor agrees to execute and deliver to the 
Collateral Agent appropriate additional dividend, distribution and other 
orders and documents to that end, PROVIDED that if such Default or Event of 
Default is waived or cured, any such dividend or distribution theretofore 
paid to the Collateral Agent shall, upon written request of the Pledgor 
(except to the extent theretofore applied to the Secured Obligations), be 
returned by the Collateral Agent to the Pledgor.

          5.05  EVENTS OF DEFAULT, ETC.  
During the period during which an Event of Default shall have occurred and be 
continuing:

          (a)  the Collateral Agent shall have all of the rights and remedies 
     with respect to the Collateral of a secured party under the Uniform 
     Commercial Code (whether or not said Code is in effect in the 
     jurisdiction where the rights and remedies are asserted) and such 
     additional rights and remedies to which a secured party is entitled 
     under the laws in effect in the States of New York and Delaware and any 
     jurisdiction where any rights and remedies hereunder may be asserted, 
     including, without limitation, the right, to the maximum extent 
     permitted by law, to exercise all voting, consensual and other powers of 
     ownership pertaining to the Collateral as if the Collateral Agent were 
     the sole and absolute owner thereof (and the Pledgor agrees to take all 
     such reasonable action as may be appropriate to give effect to such 
     right);

          (b)  the Collateral Agent may, in its name or in the name of the 
     Pledgor or otherwise, demand, sue for, collect or receive any money or 
     property at any time payable or receivable on account of or in exchange 
     for any of the Collateral, but shall be under no obligation to do so; and

          (c)  the Collateral Agent may (but shall have no obligation to, 
     except to the extent required under the Agency and Disbursement 
     Agreement), upon not less than five Business Days' prior notice to the 
     Pledgor of the time and place, with respect to the Collateral or any 
     part thereof which shall then be or shall thereafter come into the 
     possession, custody or control of the Collateral Agent, the other 
     Secured Parties or any of their respective agents, sell, lease, assign 
     or otherwise dispose of all or any part of such Collateral, at such 
     place or places as the Collateral Agent deems advisable, and for cash or 
     for credit or for future delivery (without thereby assuming any credit 
     risk), at public or private sale, without demand of performance or 
     notice of intention to effect any such disposition or of the time or 
     place thereof (except such notice as is required above or by applicable 
     statute and cannot be waived), and the Collateral Agent or any other 
     Secured Party or anyone else may be the purchaser, lessee, assignee or 
     recipient of any or all of the Collateral so disposed of at any public 
     sale (or, to the extent permitted by law, at any private sale conducted 
     in a commercially reasonable manner) and thereafter hold the same 
     absolutely, free from any claim or right of whatsoever kind, including 
     any right or 

                               PLEDGE AGREEMENT
<PAGE>
                                    - 13 -

     equity of redemption (statutory or otherwise), of the Pledgor, any such 
     demand, notice and right or equity being hereby expressly waived and 
     released.  The Collateral Agent may (but shall have no obligation to, 
     except to the extent required under the Agency and Disbursement 
     Agreement), without notice or publication, adjourn any public or private 
     sale or cause the same to be adjourned from time to time by announcement 
     at the time and place fixed for the sale, and such sale may be made at 
     any time or place to which the sale may be so adjourned.

The proceeds of each collection, sale or other disposition under this Section 
5.05 shall be applied in accordance with Section 5.09 hereof.

          The Pledgor recognizes that, by reason of certain prohibitions 
contained in the Securities Act of 1933, as amended, and applicable state 
securities laws, the Collateral Agent may be compelled, with respect to any 
sale of all or any part of the Collateral, to limit purchasers to those who 
will agree, INTER ALIA, to acquire the Collateral for their own account, for 
investment and not with a view to the distribution or resale thereof.  The 
Pledgor acknowledges that any such private sale may be at prices and on terms 
less favorable to the Collateral Agent than those obtainable through a public 
sale without such restrictions, and, notwithstanding such circumstances, 
agrees that to the extent such private sale shall have been made in a 
commercially reasonable manner, the Collateral Agent shall have no obligation 
to engage in public sales and no obligation to delay the sale of any 
Collateral for the period of time necessary to permit the respective issuer 
thereof to register it for public sale.

          5.06  DEFICIENCY.
If the proceeds of sale, collection or other realization of or upon the 
Collateral pursuant to Section 5.05 hereof are insufficient to cover the 
costs and expenses of such realization and the payment in full of the Secured 
Obligations, the Pledgor shall remain liable for any deficiency only to the 
extent provided in Section 16.6 of the Note Purchase Agreement.

          5.07  REMOVALS, ETC.
Without at least 30 days' prior written notice to the Collateral Agent, the 
Pledgor shall not (a) maintain any of its Records at any office or maintain 
its principal place of business at any place other than at the address 
indicated beneath its signature hereto or (b) change its corporate name, or 
the name under which it does business, from the name shown on the signature 
pages hereto.

          5.08  PRIVATE SALE.
The Collateral Agent and the other Secured Parties, respectively, shall incur 
no liability as a result of the sale of the Collateral, or any part thereof, 
at any private sale, pursuant to Section 5.05 hereof, conducted in a 
commercially reasonable manner.  The Pledgor hereby waives any claims against 
the Collateral Agent or any other Secured Party arising by reason of 

                               PLEDGE AGREEMENT
<PAGE>
                                    - 14 -

the fact that the price at which the Collateral may have been sold at such a 
private sale was less than the price which might have been obtained at a 
public sale or was less than the aggregate amount of the Secured Obligations, 
even if the Collateral Agent accepts the first offer received and does not 
offer the Collateral to more than one offeree.

          5.09  APPLICATION OF PROCEEDS.
Except as otherwise herein expressly provided, the proceeds of any 
collection, sale or other realization of all or any part of the Collateral 
pursuant hereto, and any other cash at the time held by the Collateral Agent 
under this Section 5, shall be applied by the Collateral Agent in accordance 
with Section 7 of the Agency and Disbursement Agreement.

          5.10  ATTORNEY-IN-FACT.
Without limiting any rights or powers granted by this Agreement to the 
Collateral Agent, while no Default or Event of Default has occurred and is 
continuing, upon the occurrence and during the continuance of any Default or 
Event of Default the Collateral Agent is hereby appointed the 
attorney-in-fact of the Pledgor for the purpose of carrying out the 
provisions of this Section 5 and taking any action and executing any 
instruments which the Collateral Agent may deem necessary or advisable to 
accomplish the purposes hereof, which appointment as attorney-in-fact is 
irrevocable and coupled with an interest.  Without limiting the generality of 
the foregoing, so long as the Collateral Agent shall be entitled under this 
Section 5 to make collections in respect of the Collateral, the Collateral 
Agent shall have the right and power to receive, endorse and collect all 
checks made payable to the order of the Pledgor representing any dividend, 
payment or other distribution in respect of the Collateral or any part 
thereof and to give full discharge for the same.

          5.11  PERFECTION.
Prior to or concurrently with the execution and delivery of this Agreement, 
the Pledgor shall deliver to the Collateral Agent all certificates identified 
in Annex 1 hereto, accompanied by undated stock powers duly executed in blank 
(or otherwise properly indorsed (within the meaning of Section 8-304 of the 
UCC).

          5.12  TERMINATION.
Upon the Termination Date, the security interest created by this Agreement 
shall terminate and all rights to the Collateral shall revert to the Pledgor, 
and upon the written request of the Pledgor containing a certification that 
the Termination Date has occurred, the Collateral Agent shall forthwith cause 
to be assigned, transferred and delivered, against receipt but without any 
recourse, warranty or representation whatsoever, any remaining Collateral and 
money received in respect thereof, to or on the order of the Pledgor.  The 
Collateral Agent shall also execute and deliver to the Pledgor upon such 
written request and certification such Uniform Commercial Code termination 
statements and such other documentation as shall be reasonably requested by 
the Pledgor to effect the termination and release of the Liens on the 
Collateral.

          5.13  EXPENSES.
The Pledgor agrees to reimburse each of the Noteholders and the Collateral 
Agent for all costs and expenses of the Noteholders and the Collateral Agent 
(including, without limitation, the fees and expenses of legal counsel) in 
connection with (a) any Default or Event of Default and any enforcement or 
collection proceeding resulting therefrom, including, without limitation, all 
manner of participation in or other involvement with (i) performance by the 
Collateral Agent of any obligation that the Pledgor has failed or refused to 
perform, (ii) bankruptcy, insolvency, receivership, foreclosure, winding up 
or liquidation proceedings, or any actual or attempted sale, or any exchange, 
enforcement, collection, compromise or settlement in respect of any of the 
Collateral, and for the care of the Collateral and defending or asserting 
rights and claims of the Collateral Agent in respect thereof, by litigation 
or otherwise, including expenses of insurance, (iii) judicial or regulatory 
proceedings and (iv) workout, restructuring or other negotiations or 
proceedings (whether or not the workout, restructuring or transaction 
contemplated thereby is consummated) and (b) the enforcement of this Section 
5.13, and all such costs and expenses shall be Secured Obligations entitled 
to the benefits of the collateral security provided pursuant to Section 3 
hereof.

          5.14  FURTHER ASSURANCES.
The Pledgor agrees that, from time to time upon the request of the Collateral 
Agent, the Pledgor will execute and deliver such further documents and do 
such other acts and things as the Collateral Agent may reasonably request in 
order fully to effectuate the purposes of this Agreement.

          6.01  NO WAIVER.
No failure on the part of the Collateral Agent or any of its agents to 
exercise and no delay in exercising, and no course of dealing with respect

agents of any right, power or remedy hereunder shall preclude any other or 
further exercise thereof or the exercise of any other right, power or remedy. 
The remedies provided herein are cumulative and are not exclusive of any 
remedies provided by law.

                                                                 Exhibit 10(ff)


                             INDEMNITY AGREEMENT


          This Indemnity Agreement dated as of June 3, 1998, between American
Crystal Sugar Company, a Minnesota cooperative (the "INDEMNITOR"), Newcourt
Capital USA Inc., a Delaware corporation ("NEWCOURT"), Crystech, LLC, a Delaware
limited liability company (the "PROJECT COMPANY") and Crystech Senior Lender
Trust, a Delaware statutory business trust ("CRYSTECH TRUST" and, together with
Newcourt and the Project Company, the "INDEMNITEES").


                               R E C I T A L S

          WHEREAS,  the Indemnitor desires that its affiliate, the Project
Company, engage Process Systems Incorporated Construction Company ("PSI") to
design, engineer and construct a molasses desugarization facility (the "MDS
FACILITY") at Indemnitor's sugar processing facility in Hillsboro, North Dakota
and other related equipment to be used by Indemnitor at its sugar processing
facilities in Hillsboro, North Dakota and Moorhead, Minnesota (the MDS Facility
and such other related equipment being collectively referred to as  the
"PROJECT").  The MDS Facility will utilize certain technology (the "IDRECO
TECHNOLOGY") provided by Idreco Inc. ("IDRECO");

          WHEREAS, in connection with submitting a bid to construct the MDS
Facility, PSI entered into a Confidentiality Agreement dated as of July 7, 1997
(the "CONFIDENTIALITY AGREEMENT") with Indemnitor and Finnsugar Bioproducts Inc.
("FINNSUGAR") and Applexion Inc. ("APPLEXION") defining certain rights and
obligations of the parties thereto with respect to certain "confidential
information" (as defined therein) belonging to Finnsugar and/or Applexion;

          WHEREAS, as a result of the Confidentiality Agreement the Project
Company, the Indemnitees who have provided financing for the Project in the form
of debt (in the case of Crystech Trust) and equity contributions (in the case of
Newcourt) may be exposed to certain actions, claims, losses and expenses arising
out of the engagement of PSI to construct the Project pursuant to the
Engineering, Procurement and Construction Contract between PSI and Crystech
dated as of May 28, 1998 ("the EPC CONTRACT") and the use of the Idreco
Technology; and

          WHEREAS, in order to provide the Indemnitees with adequate protection
and incentive to consent to the construction of the Project by PSI, the use of
the Idreco Technology and certain other risks associated with the development,
operation, ownership and financing of the Project, the Indemnitor has agreed to
enter into this Indemnity Agreement to provide indemnity to the Indemnitees as
more fully set forth herein.

          NOW, THEREFORE, in consideration of the premises and covenants
contained herein, and for other good and valuable consideration, the receipt and
adequacy of which are

<PAGE>
hereby acknowledged, the parties hereto covenant and agree as follows:

          SECTION 1.     DEFINED TERMS.
          
          (a)  Each capitalized term used and not separately defined herein 
     shall have the meaning ascribed to such term in the Note Purchase 
     Agreement dated as of the date hereof between the Project Company and 
     the Crystech Trust (the "NOTE PURCHASE AGREEMENT").
     
          (b)  Except as otherwise specified or as the context may otherwise 
     require, any reference herein to any agreement, contract or document 
     shall mean such agreement, contract or document and all schedules, 
     exhibits, attachments and annexes thereto as amended, supplemented or 
     modified and in effect from to time, as permitted by the Note Purchase 
     Agreement.
     
          SECTION 2.     INDEMNIFICATION.
          
          (a)  The Indemnitor agrees to indemnify, release, exonerate and 
     hold each Indemnitee and each of their respective trustees, officers, 
     directors, employees and agents free and harmless on demand from and 
     against any and all claims, actions, causes of action, suits, losses, 
     liabilities, damages and expenses, including without limitation 
     reasonable counsel fees and disbursements (the "INDEMNIFIED 
     LIABILITIES") incurred by such Indemnitee as a result of, arising out 
     of, or relating to (i) any claims brought against the Project Company, 
     the Project, PSI or the Indemnitees (or any of them) by Finnsugar and/or 
     Applexion or any of their respective shareholders, successors or assigns 
     or anyone acting on their behalf for patent, copyright or trademark 
     infringement or the unauthorized use of trade secrets with respect to 
     the use or license of the Idreco Technology in connection with the 
     development, construction, operation or ownership of the Project, (ii) 
     the Confidentiality Agreement, (iii) any third-party claims of the type 
     described in Section 14.2 of the EPC Contract, (iv) any Idreco Delay (as 
     defined in the EPC Contract) and (v) any present or future Environmental 
     Claim or environmental matter or condition (in each case whether known 
     or unknown) associated with the Indemnitor, its assets or operations or 
     the ownership by Indemnitor or any other Person of any real property or 
     facility leased to the Project Company or used in connection with the 
     Project or any Release (actual or threatened) of any Hazardous Materials 
     from, at or to any site or facility owned or used by Indemnitor.
     
          (b)  In furtherance of the foregoing, Indemnitor agrees to pay all 
     principal, interest and Make-Whole Amounts (if any) and any other 
     amounts due and owing (including, without limitation, following the 
     acceleration of the Notes pursuant to Section 10 of the Note Purchase 
     Agreement) under the Note Purchase Agreement and Section 4.2 of the 
     Company LLC Agreement if and for so long as any such claim, action, 
     cause of action, suit, loss, liability or expense referred to in Section 
     2(a) above, delays or impairs or slows the construction or completion of 
     the Project (or any part thereof) in accordance with the Contract Master 
     Schedule (as defined in the EPC Contract) such that Provisional 
     Performance Acceptance does not occur by the Date Certain or delays or 
     impairs the start-up, operation or performance of the MDS Facility or 
     Impairs the Tolling Agreement.
     
          (c)  Without limiting the generality of the foregoing, the scope of 
     the indemnification provided to the


                                       2
<PAGE>

     Indemnitees hereunder will extend to and include (i) if the Tolling 
     Agreement has terminated, any diminution in the value of the Project (or 
     any part thereof) caused by any of the events described in Section 2(a) 
     above and (ii) any additional Project Costs incurred by the Project 
     Company beyond those set forth in the Construction Budget as a result of 
     any of the events described in Section 2(a) above.
     
          (d)  All obligations of Indemnitor hereunder shall continue during 
     the period Indemnitees are involved in the construction and operation of 
     the Project and thereafter shall continue so long as Indemnitees may be 
     subject to any possible claim or threatened, pending or completed 
     action, suit or proceeding or liability, loss, liability, damage or 
     expense of any kind described in this Section 2.
     
          SECTION 3.     NOTIFICATION AND DEFENSE OF CLAIM.
          
          (a)  Each Indemnitee shall give prompt notice to Indemnitor and 
     each other Indemnitee of any occurrence with respect to which it is 
     entitled to indemnification, provided, however, that Indemnitor shall 
     not be relieved of its obligations hereunder on account of any failure 
     to give notice.
     
          (b)  Each Indemnitee shall give Indemnitor a reasonable 
     opportunity, at Indemnitor's expense, to resist, defend and/or settle 
     such action, suit or proceeding or cause the same to be resisted, 
     defended and/or settled by counsel for the insurer of the liability or 
     by counsel designated by Indemnitor and reasonably approved by such 
     Indemnitee, which approval shall not be unreasonably delayed or 
     withheld, provided that each Indemnitee may in any case retain separate 
     counsel and participate in such defense, at its own expense.  In the 
     event that Indemnitor fails, within a reasonable period of time, to 
     resist, defend and/or settle any such action, suit or proceeding as 
     aforesaid with counsel approved by such Indemnitee, such Indemnitee may 
     resist, defend and/or settle such action, suit or proceeding to the 
     final determination of such action, suit or proceeding, at Indemnitor's 
     expense, by counsel designated by such Indemnitee.
     
          (c)  Indemnitor hereby agrees that its obligations hereunder will 
     be paid strictly in accordance with the terms of this Indemnity 
     Agreement, regardless of any law, regulation or order now or hereafter 
     in effect in any jurisdiction affecting any of such terms or the 
     Financing Documents or affecting any of the rights of any Indemnitee 
     with respect thereto, to the extent the same may be waived.
     
          SECTION 4.     WAIVER.
          
          Except as expressly provided in this Indemnity Agreement, Indemnitor
hereby waives (i) promptness and diligence; (ii) notice of acceptance and notice
of the incurrence of any obligation by Indemnitor; (iii) notice of any actions
taken by Indemnitee, Indemnitor or any interested party under any Financing
Document or any other agreement or instrument relating thereto; (iv) all other
notices, demands and protests, and all other formalities of every kind in
connection with the enforcement of the obligations of Indemnitor hereunder, the
omission of or delay in which, but for the provision of this Section 4, might
constitute grounds for relieving


                                       3
<PAGE>

Indemnitor of its obligations hereunder; and (v) any requirement that any 
Indemnitee protect, secure, perfect or insure any security interest or lien 
in or on any property or exhaust any right or take any action against 
Indemnitor or any other person or the Project as a pre-condition to such 
Indemnitee's right to enforce this Indemnity Agreement in accordance with its 
terms.  Without limiting the generality of the foregoing, Indemnitor hereby 
waives any defense which may arise by reason of (A) the incapacity, lack of 
authority, death or disability of, or revocation hereof by, any Person or 
Persons, (B) the failure of any Indemnitee to file or enforce any claim 
against the estate of any Person or Persons, or (C) any defense based upon an 
election of remedies by such Indemnitee.

          SECTION 5.     ENFORCEMENT; PAYMENT.
          
          Each Indemnitee shall be reimbursed by Indemnitor for all reasonable
expenses (including reasonable attorneys' fees) incurred in enforcing rights or
in collecting monies due under this Agreement. All payments by Indemnitor under
this Indemnity Agreement shall be made without set-off, counterclaim or other
defense.  If Indemnitor does not pay any amount payable hereunder when due,
Indemnitor shall pay interest on such amount at an annual rate equal to the
Default Interest Rate  payable with respect to Advances outstanding until such
time as such amount, together with any accrued interest thereon shall have been
paid in full to the applicable Indemnitee.  For so long as any of the Notes are
outstanding, all amounts payable by Indemnitor hereunder to the Project Company
shall be made in the manner set forth in Section 6 of the Agency and
Disbursement Agreement.

          SECTION 6.     SEPARABILITY.
          
          Each of the provisions of this Agreement is a separate and distinct
agreement and independent of the others, so that if any provision hereof shall
be held invalid or unenforceable for any reason, such invalidity or
unenforceability shall not affect the validity or enforceability of the other
provisions hereof.

          SECTION 7.     COUNTERPARTS.
          
          This Agreement may be executed in one or more counterparts each of
which for all purposes shall be deemed to be an original and all of which taken
together shall constitute one instrument.

          SECTION 8.     SUBMISSION TO JURISDICTION.
          
          Indemnitor hereby submits to the nonexclusive jurisdiction of the
courts of the United States of America for the Southern District of New York and
of any New York State court sitting in New York City for the purposes of all
legal proceedings arising out of or relating to this Indemnity Agreement or the
indemnification contemplated hereby.  Indemnitor hereby irrevocably appoints CT
Corporation System having offices on the date hereof at 1633 Broadway, New York,
New York 10019 as the agent for service of process in connection


                                       4
<PAGE>

with any such proceedings in New York and further agrees that such service of 
process may be made by certified mail, return receipt requested, to 
Indemnitor's address specified herein or any other manner permitted by law.  
Indemnitor consents that any such action or proceeding may be brought in such 
courts and waives any objection that it may now or hereafter have to the 
venue of any such action or proceeding in any such court, including, without 
limitation, any objection that such action or proceeding was brought in an 
inconvenient court.

          SECTION 9.     GOVERNING LAW.
          
          This Agreement shall be interpreted and enforced in accordance with
the law of the State of New York.

          SECTION 10.    BINDING EFFECT.
          
          This Agreement shall be binding upon and inure to the benefit of the
Indemnitees and their successors and assigns and Indemnitor and its successors
and assigns.

          SECTION 11.    MODIFICATION.
          
          No amendment, modification, termination or cancellation of this
Agreement shall be effective unless in writing signed by all parties hereto.

          SECTION 12.    MISCELLANEOUS.
          
          (a)  No failure on the part of any Indemnitee to exercise, and no 
     delay in exercising, and no course of dealing with respect to, any 
     right, power or privilege hereunder or under any other document shall 
     operate as a waiver thereof, nor shall any single or partial exercise of 
     any right, power or privilege hereunder or under any other Financing 
     Document preclude any other or further exercise thereof or the exercise 
     of any other right, power or privilege. The rights and remedies of each 
     Indemnitee provided herein and in the Financing Documents are cumulative 
     and are in addition to, and not exclusive of, any right or remedies 
     provided by law.
     
          (b)  Crystech Trust may take or release other security for the 
     payment of the Notes, may release any party primarily or secondarily 
     liable therefor and may apply any other security held by it to the 
     reduction or satisfaction of any outstanding amounts in respect of the 
     Notes without prejudice to any of its rights under this Indemnity 
     Agreement.
     
          (c)  All notices and other communications hereunder shall be in 
     writing (including without limitation by telex or telecopy) delivered to 
     any party at its address set forth on the signature pages hereof or at 
     such other address as such party shall have notified the other parties 
     hereto.

          Section 2.3    TERMINATION BY CUSTOMER.  Customer may terminate this
Agreement (and written notice of such termination shall be given to the Company
and the Noteholders) only upon the occurrence and continuance of each of the
following events:

          (a)  The average Recovery Rate for three consecutive Tolling Periods
     shall be less than 72% and Customer shall have given prompt notice of such
     Recovery Rate to the Company and the Independent Engineer;

          (b)  The Independent Engineer shall have verified within 30 days of
     the end of such third Tolling Period that the MDS Facility shall continue
     to fail to Process Feedstock at a 72% Recovery Rate other than by reason of
     operational failure by the Operator (it being understood that there shall
     be a presumption that such Recovery Rate failure is attributable to
     operational failure by the Operator); and

          (c)  The Company shall not have cured such failure of the MDS Facility
     to Process Feedstock at a Recovery Rate of not less than 72% within 180
     days of the date from which Customer shall have given notice to the Company
     and the Independent Engineer pursuant to Section 2.3(a).

          Section 2.4    CONTINUING OBLIGATION TO PAY TOLLING FEE.
Notwithstanding the foregoing, Customer shall continue to pay all Tolling Fees
until it shall have terminated this Agreement in accordance with Section 2.3,
regardless of whether Customer delivers Feedstock to the Point of Receipt.

          Section 2.5    EFFECTS OF TERMINATION.  Termination of this agreement,
for any reason, shall not discharge either Party from any obligation it owes to
the other Party under this Agreement by reason of any transaction, loss, cost,
damage, expense, indebtedness or liability that shall occur or arise (or the
circumstances, events, or basis of which shall occur or arise) prior to any such
termination.  It is the intent of the Parties that any such obligation owed
(whether the same shall be known or unknown at the time this Agreement was
terminated or whether the circumstances, events or basis of the same shall be
known or unknown at such termination) shall survive such termination.

          Section 3.1    TOLLING SERVICES.  Subject to the provisions of this
Agreement, beginning on the Start Date and continuing throughout the term of
this Agreement, the Company shall provide to Customer and Customer shall pay for
Tolling Services as provided herein.  The Company shall notify when the Molasses
Desugarization Facility is ready to commence receiving (or has received)
Feedstock, which notice the Company shall not give without the concurrence of
the Independent Engineer and Customer.  The MDS Facility shall be deemed to be
ready to receive Feedstock once the MDS Facility has achieved a Recovery Rate of
at least 72%, regardless of any remedial action taken thereafter in accordance
with the EPC Contract.

          Section 3.2    DELIVERY OF FEEDSTOCK AND REDELIVERY OF TOLLING
PRODUCT.

          (a)  Subject to the Company's curtailment rights under Article 9,
Customer may deliver to the Point of Receipt quantities of Feedstock to be
Processed by the Company at the Molasses Desugarization Facility; PROVIDED
Customer may not deliver more than the Maximum Daily Capacity unless the MDS
Facility is capable of Processing such additional Feedstock without adversely
affecting the reliability or useful life of the MDS Facility.

          (b)  After receiving Customer's Feedstock at the Point of Receipt, the
Company shall be deemed to be in control and possession of said Feedstock and
Tolling Product Processed therefrom until it is redelivered to Customer at the
applicable Point of Redelivery.  Notwithstanding the above, unless otherwise
specified herein, title to and risk of loss with respect to Feedstock delivered
by Customer to the Company under this Agreement shall remain with Customer, even
during periods when it is in the possession and control of the Company.

          (c)  With respect to Customer's Feedstock to be delivered to the Point
of Receipt and Tolling Product to be redelivered by the Company to Customer at
the applicable Point of Redelivery, Customer shall be responsible for making all
necessary arrangements, and provide at its sole cost and expense all equipment
and labor, to deliver Feedstock to the Point of Receipt and transport all
Tolling Extract from the Points of Redelivery.  Subject to Section 7.4, Customer
shall be responsible for, and shall hold the Company harmless from, all costs
associated with delivering Feedstock to the Company at the Point of Receipt.

          (d)  Customer covenants that it will have good, valid, and marketable
title to all Feedstock delivered to the Point of Receipt, free and clear of all
liens, encumbrances, and claims whatsoever, and other than inchoate liens,
charges or encumbrances arising by operation of Law and other than Liens arising
under the Working Capital Facility and shall maintain such title.  Customer
shall indemnify, defend and hold the Company harmless from and against all
suits, actions, damages, costs, losses, and expenses arising from or out of
adverse claims of any Person relating to Feedstock delivered to the Point of
Receipt for Customer's account or any Tolling Product extracted therefrom,
including claims for any taxes, fees, tariffs or other charges applicable to
such Feedstock or Tolling Product or to the receipt thereof by the Company.

          (e)  To the extent the Company Processes Feedstock (including any 
Off-Spec Feedstock and all Feedstock Processed in connection with the testing 
of the Molasses

Desugarization Facility contemplated by the EPC Contract), Customer shall 
have no right to reject redeliveries of Tolling Product Processed therefrom.

          Section 3.3    FEEDSTOCK DELIVERY.  Customer will comply with all
applicable safety laws, rules and regulations in delivering Feedstock to the
Company.  Customer may request that the Company, at Customer's sole cost and
expense, make alterations to the Molasses Desugarization Facility that are
necessary to ensure that the equipment Customer uses to deliver Feedstock to the
Company is compatible with the Molasses Desugarization Facility; PROVIDED,
HOWEVER, in no event shall the Company be obligated or required to make any
material alternation to the Molasses Desugarization Facility in order to
accommodate Customer's Feedstock delivery equipment if in the opinion of the
Company or the Independent Engineer such alteration could reasonably be expected
to reduce the reliability or useful life of the MDS Facility.

          Section 3.4    TESTING; OBLIGATIONS OF THE COMPANY AT MDS FACILITY;
OPERATIONAL COORDINATION.  Customer shall deliver to the Company (at Customer's
sole cost and expense) at the Point of Receipt a sufficient quantity of
Feedstock to permit the Company to perform all testing required under the EPC
Contract to achieve Provisional Performance Acceptance.

          Section 3.5    UTILITIES.  Customer shall make available to the
Company all Utilities necessary or required for the Operation of the MDS
Facility.

          Section 3.6    SCHEDULING OF MAINTENANCE.  The Company shall have the
right to interrupt or to discontinue Tolling Services in whole or in part, from
time to time, in order to repair, maintain or improve the Molasses
Desugarization Facility.  The Company shall provide prior notice to Customer, to
the extent reasonably practicable, of any such curtailment, interruption, or
discontinuance.  The Company shall schedule repairs, construction, and
maintenance activities so as to reasonably minimize disruptions of Tolling
Services to Customer, and shall provide to Customer no later than August 31 of
each Year a non-binding schedule of planned repair, construction, and
maintenance activities for the following Year.

          Section 3.7    EXCLUSIVE ARRANGEMENTS.  Until the termination of this
Agreement in accordance with Article 2, the Company shall not Process any
Feedstock other than Feedstock delivered by Customer for Processing pursuant to
the terms set forth herein.

Specifications shall be referred to as "OFF-SPEC FEEDSTOCK".

          Section 5.2    FAILURE OF FEEDSTOCK TO CONFORM TO SPECIFICATIONS.

          (a)  Each Party shall notify the other as soon as reasonably
practicable of any existing or anticipated failure of the Feedstock to conform
to the Feedstock Specifications, giving the details of the variance and the
cause thereof.

          (b)  At Customer's request, the Company shall use commercially
reasonable efforts (which efforts shall not require the Company to apply for, or
seek to amend or to modify, any Governmental Approval or reduce the useful life
of the MDS Facility) to take delivery of and Process any Off-Spec Feedstock, and
Customer shall reimburse the Company for all costs incurred (over and above
those normally incurred) in receiving and Processing Off-Spec Feedstock.

each Payment Date, for the Tolling Period ending immediately prior to such
Payment Date, and on the Termination Date, for the period commencing with and
including the Payment Date immediately prior to the Termination Date through and

          All Tolling Fees shall be payable without withholding, setoff or
deduction regardless of any events or occurrences whatsoever (whether or not
within the control of the Parties) and whether or not Customer has delivered any
Feedstock to the MDS Facility and shall not be reduced for any reason other than
as permitted by Section 2.3.

          (a)  On or before each Payment Date and on the Termination Date, the

1% and other equipment as is necessary to measure the volume of Tolling 
Product redelivered hereunder (the "INCREMENTAL METERING EQUIPMENT").  In the 
event the Incremental Metering Equipment is out of service, or registering 
inaccurately, the volumes of Tolling Product delivered hereunder shall be 
estimated as follows, in descending order of priority:

          (a)  By using the registration of any check meter or meters if
installed and accurately registering; or

          (b)  By correcting the error if the percentage of error is
ascertainable by calibration, test, or mathematical calculation; or

          (c)  By estimating the quantity of Tolling product delivered during
prior periods under similar conditions when any meter was registering
accurately.

          Section 7.2    PRESERVATION OF RECORDS.  The Company shall preserve
for a period of at last two years all test data, charts, and other similar

                                 FORCE MAJEURE

          Section 8.1    DEFINITION OF FORCE MAJEURE.  For purposes of this
Agreement, "FORCE MAJEURE" means any cause beyond the reasonable control of and
not the fault or negligence of the Party claiming the Force Majeure.  An event
of Force Majeure shall excuse the performance under this Agreement of the Party
claiming Force Majeure (including, in the case of the Company, Processing
Feedstock at a Recovery Rate of at least 72%) if such event causes the
nonperformance or inability to perform.  Except as provided in Section 8.3, the
Parties shall be excused from performing hereunder (other than indemnification
and payment obligations, including, without limitation, Tolling Fees), and shall
not be liable in damages or otherwise for nonperformance, in each case, to the
extent the nonperformance or inability to perform is due to a Force Majeure
event.

          Section 8.2    EXAMPLES OF FORCE MAJEURE.  Provided that the
provisions of Section 8.1 are met, Force Majeure events include, but are not
limited to, the following:  acts of God; strikes; acts of public enemy; war;
blockades; boycotts; riots; insurrections; epidemics; earthquakes; storms;
floods; civil disturbances; fires; explosions; binding orders; and directives or
regulations of any court, or duly constituted government authorities having
jurisdiction, that have been resisted in good faith by all reasonable legal
means.  The specific Force Majeure events listed in the prior sentence shall not
be construed as excluding any other event as long as such event meets the
provisions of Section 8.1.

          Section 8.3    CONSEQUENCES OF FORCE MAJEURE.  If a Party is 
rendered wholly or partly unable to perform its obligations under this 
Agreement due to a Force Majeure, that Party shall be excused from whatever 
performance is affected by the Force Majeure to the extent so affected, 
provided that:  (i) the non-performing Party, within 10 Days after the 
occurrence of, or such Party's discovery of, the Force Majeure, gives the 
other Party written notice describing the particulars of the occurrence and 
its estimated duration; (ii) the suspension of performance is of no greater 
scope and of no longer duration than is required by the Force Majeure, 
consistent with

                                                                              12

prudent industry, engineering and maintenance practices, to remedy its 
inability to perform and resume in full its performance under this Agreement, 
provided that this obligation shall not require the settlement of any strike, 
walkout, or other labor dispute on terms that, in the sole judgment of the 
Party involved in the dispute, are contrary to its best interest.  Nothing in 
this Article 8 shall relieve either Party of its obligation to perform its 
indemnification and payment obligations pursuant to this Agreement, including 
the payment of Tolling Fees.

                                   ARTICLE 9
                                  CURTAILMENT

          Section 9.1    CURTAILMENT RIGHTS.  The Company shall have the right
to curtail, interrupt, or discontinue Tolling Services in whole or in part from
time to time and at any time (but not more than necessary) (a) for reasons of
Force Majeure, (b) to the extent necessary in the Company's reasonable judgment
to comply with applicable Laws, (c) to the extent necessary in the Company's
reasonable judgment to perform emergency maintenance of the MDS Facility and for
ordinary course maintenance and (d) to the extent necessary in the Company's
reasonable judgment to protect Persons and property, including the MDS Facility,
from harm or damage due to operational or safety conditions.

          Section 9.2    NOTICE OF CURTAILMENT.  The Company shall promptly
provide Customer with a notice of curtailment or interruption at the time and in
a manner that is reasonable under the existing conditions, but the failure to
provide such prompt notice shall not affect the Company's right to effect or
continue such curtailment or interruption.  Customer shall have the
responsibility to inform its suppliers, downstream customers and all others
involved in the transaction as to any curtailment or interruptions.

Company at the Point of Receipt and (b) after redelivery of Sugar Extract by the
Company to Customer at the Point of Redelivery with respect to Sugar Extract,
and Customer shall indemnify, defend, and hold the Company harmless from any
damage or injury, liability, or claim caused by or relating to Feedstock or
Sugar Extract while in Customer's possession and control, except for damages and

possession and control and arising from the gross negligence or willful
misconduct of the Company or as otherwise provided herein.  The Company shall be
in possession and control of the Feedstock and Sugar Extract covered by this
Agreement after the receipt of Feedstock at the Point of Receipt and until
redelivery of the Sugar Extract at the Point of Redelivery with respect to the
Sugar Extract, and the Company shall indemnify, defend, and hold Customer
harmless from any damage or injury, liability, or claim caused by or relating to
Feedstock or Sugar Extract while in the Company's possession and control, except
for damages and injuries caused by or relating to Feedstock or Sugar Extract
while in the Company's possession and control and arising from the gross

Customer may recover under this indemnity solely out of funds available from 
the proceeds of the Tolling Fees payable hereunder and liability insurance 
proceeds.

          Section 10.2   CUSTOMER LIABILITY FOR DAMAGES.  Customer recognizes
and agrees that its failure to take redelivery of Sugar Extract Processed for
Customer's account under this Agreement shall damage the Company.  Therefore,
Customer will pay the Company for any and all costs arising from such failure.

provided for in this Agreement, no party hereto or any of its Affiliates or any
of their respective directors, officers, shareholders, partners, employees,

or any of their respective directors, officers, shareholders, partners,
employees, agents, and representatives or any of their respective heirs,
successors, and assigns for claims for incidental, consequential, indirect,
special, punitive, or exemplary damages to persons or property, whether arising

                                  ASSIGNMENT

          Section 11.1   ASSIGNMENT BY CUSTOMER.  Customer shall not assign or
transfer any of its rights, benefits, obligations, or duties under this
Agreement without the prior written consent of the Company and the Noteholders,
provided that Customer may assign its rights hereunder to St. Paul Bank for
Cooperatives (or a successor lender to ACS that executes a consent and agreement
substantially similar to the St. Paul Bank Consent) as collateral security for
its obligations under the Working Capital Facility (or a successor working
capital facility for Customer).

          Section 11.2   ASSIGNMENT BY THE COMPANY TO NOTEHOLDERS.  The Company
may, without the consent of Customer, assign its rights and benefits but not its
obligations and duties under this Agreement to the Noteholders as collateral
security in order to obtain financing, provided that the Company shall not be
relieved of its responsibility to carry out its duties and obligations under

                              DISPUTE RESOLUTION

          Section 12.1   DISPUTES.

          (a)  Subject to Section 12.1(c), the Parties agree to make a diligent,
good faith attempt to resolve all disputes before either Party commences
arbitration with respect to the subject matter of any dispute.  If the
representatives of the Parties are unable to resolve a dispute within 10 Days
after notice of the existence of the dispute from one Party to the other (the
"DISPUTE NOTICE"), either Party may, by a second notice to the other Party,
submit the dispute to the chief executive officers of the Company and Customer
(collectively, "CEO'S").  A meeting date and place shall be established by
mutual agreement of the CEO's.  However, if the Parties are unable to agree, the
meeting shall take place at the ACS Hillsboro Complex, 5 Days after the date of
such second notice.  The CEO's shall meet in person and shall in good faith
attempt to resolve the dispute.

          (b)  If such dispute involves in whole or in part (i) a technical
engineering issue, then the CEO's will in good faith attempt to appoint a
suitably experienced and qualified independent engineering firm reasonably
satisfactory to each of them, (ii) a legal issue, then the CEO's will in good
faith attempt to appoint an independent lawyer or law firm reasonably
satisfactory to each of them, or (iii) a financial issue, then the CEO's will in
good faith attempt to appoint a financial advisor or investment bank
satisfactory to each of them, in each case to act in relation to such dispute
and to render a recommendation in respect thereof.

          (c)  If the dispute remains unresolved 5 Days following such meeting
or the receipt of such recommendation, as the case may be, either Party may
commence arbitration.  Nothing herein shall prevent a Party from commencing
arbitration at any time (i) when the delay required for performance hereunder
might materially and adversely affect such Party's interest; (ii) when the other
Party fails to fulfill its obligations under this Article 12; or (iii) after the
expiration of 90 Days after issuance of the Dispute Notice.

and experience in such technical matters.  The two arbitrators so appointed
shall appoint the third arbitrator who shall serve as the chairman of the
arbitral tribunal.  If a Party fails to appoint its arbitrator within a period

          (e)  Neither the execution and delivery by Customer of this Agreement,
nor the consummation by Customer of any of the transactions contemplated hereby,
requires the consent or approval of, the giving of notice to, the registration
with, the recording or filing of any document with, or the taking of any other
action in respect of any Governmental Body, except those which have been duly
obtained and are in full force and effect or not yet required, but which

upon due application therefor.

          (f)  Customer is aware of all the legal requirements and business
practices that must be followed in performing its obligations hereunder and, in

          (h)  Customer is not a party to any legal, administrative, arbitral,

one or more instances upon strict performance of any provisions of this
Agreement, or to take advantage of any of its rights hereunder, shall not be

          Section 14.4   BENEFICIARIES.  This Agreement shall be binding upon
and is intended solely for the benefit of the Parties hereto and their

construed to create any duty to, or standard of care with reference to, or any
liability to, any Person not a Party to this Agreement.

          Section 14.5   RELATIONSHIP OF PARTIES.  This Agreement shall not be
interpreted or construed to create an association, joint venture, or partnership

an agent or representative of, or to otherwise bind, the other Party.

          Section 14.6   SURVIVAL OF INCURRED OBLIGATIONS.  Cancellation,

this Agreement by the other Party, provided that no waiver by or on behalf of a
Party of any breach of this Agreement shall take effect or be binding on that
Party unless the waiver is in writing.  A waiver of breach shall be effective
only for the Party providing such waiver and shall extend only to the particular
breach waived, and shall not limit or otherwise affect the rights of the Party
providing such waiver with respect to any other or future breach.

as expressed in this Agreement.

          Section 14.11  CHOICE OF LAW.  This Agreement shall be governed by and

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


The Recovery Rate will be calculated as follows:

           (Bm)(1-Qm)(Mm)(Za)
          -------------------- (100%) = System Performance %P
          (.80)(1-.60)(600)(.81)

Where:    Bm  =   Actual Brix of the feed molasses
          Qm  =   Actual true purity of feed molasses
          Mm  =   Actual tons of molasses worked
          Za  =   Z=(R)(1-(Qg-Qe)(Qs)/1-Qs)(Qc))

where:    Za  =   Overall recovery of sucrose or the percentage of the sugar 
                  in the feed molasses that will be recovered as granulated 
                  sugar.
          R   =   Measured recovery of the separators or the percentage of the 
                  sugar in the feed molasses that ends up in the extract.
          Qg  =   Purity of the granulated sugar or 100%
          Qc  =   Purity of the extract
          Qs  =   Purity of the secondary molasses or the purity of the 
                  molasses that the sugar end will make when processing extract.
                  (This is set at 62.5% to eliminate the effect of poor sugar 
                  end operation.)

submitted to any Government Agency by Operator shall be furnished to Owner. 
Without limiting the foregoing, Operator shall monitor the Recovery Rate of 
the MDS Facility and promptly notify owner, Lender and Lender's technical 
advisor if the Recovery Rate for any period of four (4) consecutive weeks

relating thereto for purposes of inspection and review, PROVIDED, HOWEVER, 
that any access or inspection shall be subject to confidentiality limitations

          SECTION 5.1    PLANT MANAGER.  No later than the commencement of 
construction under the Construction Contract (or such other date as the 
parties may mutually agree), Operator shall appoint an individual ("PLANT 
MANAGER"), subject to approval of Owner, who will direct and manage

          SECTION 5.2    ANNUAL OPERATING PLAN AND BUDGET.

          5.2.1     BUDGET FOR PREOPERATIONAL PHASE-IN SERVICES.  Not later 
than _______________, 199_ (or such other date as the parties may mutually 
agree), Operator shall prepare and submit to Owner a proposed budget for the 
Preoperational Phase-In Services. Such budget shall include an itemized 
estimate of all Reimbursable Costs.  Owner shall promptly review Operator's 
proposed budget for Preoperational Phase-In Services and may, by written 
request, seek changes, additions, deletions and modifications to such budget. 
Owner and Operator will use their best efforts to agree upon such budget, 
which shall be approved in writing by both Parties.  Operator will use its 
best efforts to keep down Reimbursable Costs for the Preoperational Phase-In 
Services to the levels established in the agreed-upon budget therefor.  

          5.2.2     ADOPTION OF ANNUAL BUDGET AND ANNUAL OPERATING PLAN.  At 
least 3 months prior to the anticipated CCC Time, and 60 days prior to the 
beginning of each Operating Year thereafter, Operator shall prepare and 
submit to Owner a proposed annual budget for such year, established on a 
monthly basis, which shall include a separate operating budget and capital 
budget and shall set forth anticipated operations, repairs and capital 
improvements (including Major Maintenance), routine maintenance and overhaul 
schedules, procurement (including equipment acquisitions and spare parts and 
consumable inventories indicating a breakdown of capital items and expense 
items), staffing, personnel and labor activities (including unit rates for 
labor and holidays to be observed), administrative activities, data regarding 
other work proposed to be undertaken by Operator and regarding expected 
environmental performance, together with an itemized estimate, in detail 
reasonably acceptable to Owner, of all Reimbursable Costs to be incurred in 
connection therewith (the "ANNUAL BUDGET").  Such Annual Budget shall be 
accompanied by an annual operating plan setting forth the underlying 
assumptions 

                                    - 15 -
<PAGE>

and implementation plans in connection with the Annual Budget ("ANNUAL 
OPERATING PLAN"); provided that the Annual Operating Plan with respect to the 
MDS Facility will provide that the MDS Facility operate at all times at a 
Recovery Rate of not less than seventy-two percent (72%).  Owner shall 
promptly review Operator's proposed Annual Budget and Annual Operating Plan 
and shall either approve them or may, by written request, require changes, 
additions, deletions and modifications.  Owner and Operator will use their 
best efforts to agree upon a final Annual Budget and Annual Operating Plan by 
30 days prior to such Operating Year.  Owner's approval of the Annual Budget 
and Annual Operating Plan shall not be unreasonably withheld.  Such final 
Annual Budget and Annual Operating Plan shall remain in effect throughout the 
applicable Operating Year, subject to such other updating, revision and 
amendment as may be proposed by either Party and consented to in writing by 
the other Party. 

          Any actions proposed under the Annual Operating Plan shall be 
consistent with  Operator's obligations set forth herein.  Operator shall 
notify Owner as soon as reasonably possible of any material deviations or 
discrepancies from the projections contained in the Annual Operating Plan.

          If an event of Force Majeure occurs which results in increased 
costs to Operator, Operator shall be entitled to an adjustment in the Annual 
Budget reflecting the reasonable value of any such increased costs from such 
event.  In the case of an event of Force Majeure which results in decreased 
costs to Operator, Owner shall be entitled to an adjustment in the Annual 
Budget reflecting the reasonable value of any such decreased costs from such 
event.

          5.2.3     ANNUAL REPORTS.  As soon as available, and in any event 
within 90 days after the end of each Operating Year, Operator shall submit to 
Owner an annual report certified by the Chief Financial Officer of Operator 
describing all of the Facility operations for such Operating Year and 
presenting a comparison of such Facility operations with the budget set forth 
in the Annual Operating Plan and Annual Budget for such Operating Year and 
with those obtained for the preceding Operating Year, if any.  Within 30 days 
after the submission of each annual report, the Plant Manager shall meet with 
Owner to review and discuss the report and to report upon any other aspects 
of the Facility operations that Owner may request. 

          5.2.4     LITIGATION; PERMIT LAPSES.  Upon obtaining knowledge 
thereof, Operator shall submit prompt written notice to Owner of: (i) any 
litigation, claims, disputes or actions, threatened or filed, concerning the 
Facility or the Services to be performed hereunder; (ii) any refusal or 
threatened refusal to grant, renew or extend or any action pending or 
threatened that might affect the granting, renewal or extension of any 
license, permit, approval, authorization or consent; (iii) any dispute with 
any Government Agency; (iv), all penalties or notices of violation issued by 
any Government Agency; and (v) any breach or contravention of any applicable 
Law, permit, license or approval; which in each case might have a material 
adverse effect on the operation or maintenance of the Facility.

          5.2.5     OTHER INFORMATION.  Operator shall promptly submit to 
Owner any material information concerning new or significant aspects of the 
Facility operations and, upon 

                                    - 16 -

Owner's reasonable request, shall promptly submit any other information 
concerning the Facility or its Services.  Such information may include any 
information and certifications reasonably required by any Lender.

          5.2.6     RECORDS RETENTION.  Operator shall retain and preserve

performance of the Services, Owner shall pay Operator, in the manner and at 
the times specified in this Section 6, all Reimbursable Costs all as further 
described herein to the extent Owner has recovered all amounts due under the 
Tolling Agreement.

          SECTION 6.2    REIMBURSABLE COSTS.  Owner shall reimburse Operator 
for certain reasonable costs ("REIMBURSABLE COSTS") incurred in the 
performance of the Services and in accordance with Operator's established 
policies, practices and rates then in effect for allocating such costs to 
other unrelated parties. Such Reimbursable Costs shall include:

          6.2.1     PAYROLL AND RELATED PERSONNEL COSTS.

          (a)  Payroll costs and related expenses incurred by Operator for 
     home office employees in accordance with its established personnel 
     policies (including all salaries and wages of personnel engaged in 
     and directly related to the performance of the Services hereunder) 
     and Operator's then current established rate for payroll additives; and

          (b)  Payroll costs and related expenses incurred by Operator for 
     employees assigned to the Facility site in accordance with its 
     established personnel policies (including all salaries and wages of 
     personnel involved directly in the performance of the Services 
     hereunder) and Operator's then current established rate for payroll 
     additives.

          6.2.2     OUT-OF-POCKET COSTS AND RATES.  All out-of-pocket costs 
and rates incurred in the performance of the Services, regardless of whether 
the Services are rendered at the Facility Site or at Operator's home office, 
but which costs and rates are not included as part of the payroll costs and 
expenses described above.

          6.2.3     MANNER AND TIMES OF PAYMENT OF REIMBURSABLE COSTS.  Not 
later than the beginning of each Operating Year, Operator will prepare and 
deliver to Owner a budget indicating the projected Reimbursable Costs for 
such Operating Year.  Operator will also, on a quarterly basis, review and 
(if requested by Owner) prepare and deliver to Owner a revised budget 

                                    - 17 -
<PAGE>

for the remainder of the Operating Year, indicating the projected 
Reimbursable Costs for the remainder of the Operating Year.  On a monthly 
basis, Operator will submit to Owner an invoice for the Reimbursable Costs 
paid or incurred by Operator during the preceding month.  Owner shall pay to 
Operator the amount set forth on each monthly invoice on the Payment Date (as 
that term is defined in the Tolling Agreement) occurring not less than 30 
days after receipt of the invoice.  

          6.2.4     ADJUSTMENTS AND CONDITIONS.  Notwithstanding the payment 
of any amount pursuant to the foregoing provisions, no payment made pursuant 
to the foregoing provisions shall be considered as approval or acceptance of 
the Services performed hereunder and Owner shall remain entitled to conduct a 
subsequent audit and review of all Reimbursable Costs incurred by Operator 
and paid by Owner hereunder for a period of [3] years from and after the 
close of the Operating Year in which such Reimbursable Costs were incurred.  
If, pursuant to such audit and review, it is determined that any amount 
previously paid by Owner did not constitute a due and payable item of 
Reimbursable Costs, Owner may recover such amount from Operator or deduct or 
cause to be deducted such amount from any payment that thereafter may become 
due to Operator.

                                 SECTION 7

                                    TERM

          SECTION 7.1    TERM.  The term of this Agreement shall commence on 
the Effective Date and continue for a period equal to the longer of (i) 12

termination pursuant to Sections 7.2 and 7.3.

          SECTION 7.2    TERMINATION BY OWNER.  Owner shall be permitted to 
terminate this Agreement if any of the following events occur:  (i) a 
voluntary Winding-Up of Operator; (ii) an Event of Default has occurred under 
the Note Purchase Agreement; or (iii) the Tolling Agreement terminates.  
Promptly after the date of termination, Operator shall be paid for the 
Services rendered by Operator through such termination date, including all 
fees earned through the date of termination but not paid through such date.  
Except as expressly provided in this Section 7.2, Owner shall not be liable 
for any costs incident to termination in the case of any termination under 
the foregoing clauses.

          SECTION 7.3    TERMINATION BY OPERATOR.  Operator shall be 
permitted to terminate this Agreement if any of the following events occur:  
(i) a payment default by Owner that is not cured within 180 days after the 
date on which such payment is due provided Owner has received written notice 
of such default and has received payment in full from ACS of all tolling fees 
due and owing under the Tolling Agreement; (ii) a Winding-Up of Owner; (iii) 
a material default by Owner of any other obligation under this Agreement

or (iv) the 

                                    - 18 -

Owner Acceptance, normal wear and tear excepted, and with the equivalent 
supply of spare parts and any other operating items (other than items for 
which Owner is responsible) as were provided by Owner to Operator at the CCC 
Time, or such modified supply thereof as has been approved by Owner (and 
shall be reimbursed for all Reimbursable Costs incurred in connection 
therewith).  All special tools, improvements, inventory of supplies, spare 
parts, safety equipment (in each case as provided to or obtained by or 
provided by Operator during the term of this Agreement) and any other items 
furnished on a Reimbursable Cost basis under this Agreement will be left at 
the Facility and will become or remain the property of Owner without 
additional charge.  Owner shall also have the right, in its sole discretion, 
to directly assume and become liable for any contracts or obligations that 
Operator may have undertaken with third parties in connection with the 
Services.  Operator shall execute all documents and take all other reasonable 
steps requested by Owner that may be required to assign to and vest in Owner 
all rights, benefits, interests and title in connection with such contracts 
or obligations; PROVIDED, HOWEVER, that Owner shall indemnify and hold 
harmless Operator for all liabilities arising out of events and obligations 
thereunder arising after the date of any such assumption.

                                 SECTION 8

                                 INSURANCE

          SECTION 8.1    GENERAL.  The provisions of this Section 8 do not 
modify or change or abrogate any responsibility of Operator stated elsewhere 
in this Agreement or any other Facility Agreement.  Owner assumes no 
responsibility for the solvency of any insurer or the failure of any insurer 
to settle any claim.  A summary of certain provisions of Operator's and 
Owner's policies are set forth below.  

          SECTION 8.2    OPERATOR INSURANCE.  Operator shall obtain and 
maintain as a Reimbursable Cost hereunder (including any applicable 
deductibles (subject to Section 8.6), any net premiums after dividends and/or 
retrospective premiums and any losses in excess of insurance coverage) the 
insurance set forth with respect to the Operator set forth in Schedule VI to 
the Note Purchase Agreement.

          SECTION 8.3    CERTIFICATES; PROOF OF LOSS.  On or before the 
required date for the insurance to be provided hereunder, Operator shall 
furnish certificates of insurance to the Owner evidencing the insurance 
required hereunder.  The Party maintaining each insurance policy hereunder 
shall make proofs of loss under each such policy and shall take all other 
action reasonably required to ensure collection from insurers for any loss 
under any such policy. 

                                    - 19 -

Operator shall provide Owner with copies of the insurance policies obtained 
by it promptly upon receipt thereof.

          SECTION 8.4    DEDUCTIBLES.  Except as provided herein, Owner shall 
be liable for the payment of all deductibles on insurance policies obtained 
pursuant to Section 8.2.  In the event of a claim under a policy described in 
Section 8.2 that is attributable to Operator's (including its employees' or 
agents') negligence or willful misconduct, Operator shall be liable for the 
payment of such deductible.  In the event that a claim under a policy of 
comprehensive general liability insurance covering personal injury or 
property damage to third parties is attributable to the negligence or willful 
misconduct of Owner and Operator, to the extent Operator would otherwise be 
liable for the payment of deductible hereunder, Owner and Operator shall be 
responsible for that portion of the deductible that would be assigned to it 
under a comparative negligence standard.

                                 SECTION 9

                             INDEMNIFICATION

          SECTION 9.1    BY OPERATOR.  

          9.1.1     GENERAL INDEMNITY.  Subject to the provisions of Section 
10, Operator shall indemnify, defend and hold harmless the Owner Indemnified 
Parties from and against any and all suits, actions, liabilities, legal 
proceedings, claims, demands, losses, costs and expenses of whatsoever kind 
or character, including reasonable attorneys' fees and expenses, for injury 
or death of persons or physical loss of or damage to property of Persons 
arising from Operator's (including its employees' or agents') negligence or 
willful misconduct in connection with performance of the Services or any 
other matter related to its obligations hereunder.

          9.1.2     INDEMNITY FOR VIOLATION OF LAW.  Operator shall also 
indemnify, defend and hold harmless the Owner Indemnified Parties from and 
against any and all regulatory penalties or fines (other than Environmental 
Claims which shall be governed by Section 10), and reasonable expenses 
(including attorneys' fees and expenses) arising from Operator's violation of 
any Law, license, permit, or government approval.

          9.1.3     INDEMNITY FOR PATENT INFRINGEMENT.  If any of the 
Services would infringe upon any patent, trademark or copyright or would 
involve the unauthorized use of a third Person's trade secrets, Operator 
agrees to render consultation, assistance and modifications to the Services 
as necessary to avoid such infringement or unauthorized use.  If any Owner 
Indemnified Party is charged with infringement or unauthorized use by reason 
of the Services or of the operation or sale of the Facility, Operator agrees 
to fully defend and indemnify that Owner Indemnified Party from any and all 
suits, actions, legal proceedings, claims, demands, losses, costs and 
expenses and shall settle such claim, action, proceeding or suit (at 
Operator's expense) without impairing the operation of the Facility.

          9.1.4     COSTS.  It is understood and agreed by the Parties that 
any costs or expenses incurred by Operator pursuant to its indemnity 
obligations under this Section 9.1 shall not constitute Reimbursable Costs.

          SECTION 9.2    BY OWNER.  

          9.2.1     GENERAL INDEMNITY.  Subject to the provisions of Section 
10, Owner shall indemnify, defend and hold harmless the Operator Indemnified 
Parties from and against any and all suits, actions, liabilities, legal 
proceedings, claims, demands, losses, costs and expenses of whatsoever kind 
or character, including reasonable attorneys' fees and expenses, for injury 
or death of persons or physical loss of or damage to property of Persons and 
entities other than Operator arising from Owner's (including its employees or 
agents) negligence or willful misconduct in connection with the performance 
of its obligations hereunder.

          9.2.2     INDEMNITY FOR VIOLATION OF LAW.  Owner shall also 
indemnify, defend and hold harmless the Operator Indemnified Parties from and 
against any and all regulatory penalties or fines (other than any 
Environmental Claims which shall be governed by Section 10), and reasonable 
expenses (including attorneys' fees and expenses) arising from Owner's 
violation (other than through any breach of Section 9.1.2) of any Law, 
license, permit, or government approval.

          SECTION 9.3    COOPERATION REGARDING CLAIMS.  If any Party hereto 
(each an "INDEMNIFIED PARTY") shall receive notice or have knowledge of any 
claim that may result in a claim for indemnification by such Indemnified 
Party against a Party pursuant to Section 9 or 10, such Indemnified Party 
shall, as promptly as possible, give the indemnifying Party notice of such 
claim, including a reasonably detailed description of the facts and 
circumstances relating to such claim, and a complete copy of all notices, 
pleadings and other papers related thereto, and in reasonable detail the 
basis for its potential claim for indemnification with respect thereto; 
PROVIDED that failure promptly to give such notice or to provide such 
information and documents shall not relieve the indemnifying Party from the 
obligation hereunder to respond to or to defend the Indemnified Party failing 
to give such notice against such claim. The Party against whom 
indemnification is claimed shall, upon its acknowledgment in writing of its 
obligation to indemnify the Indemnified Party seeking indemnification and for 
Owner, subject to the rights of Lender, be entitled to assume the defense or 
to represent the interests of the Indemnified Party seeking indemnification 
in respect of such claim, which shall include the right to select and direct 
legal counsel and other consultants, appear in proceedings on behalf of such 
Indemnified Party and to propose, accept or reject offers of settlement, all 
at its sole cost.

determining existence of a quorum, but consent or opposition shall be counted 
as a vote in favor of or against the proposal and shall be entered in the 
minutes or other record of action at the meeting, if the proposal acted on at

                             INDEMNIFICATION

       8.1    INDEMNIFICATION. 

       (a)    INDEMNIFICATION BY COMPANY.  The Company shall indemnify,
              hold harmless and defend the Members, the Managers and their
              respective affiliates, agents, officers, directors, partners,
              shareholders and employee (each an "Indemnified Person") to
              the full extent lawful, from and against any loss, expense,
              damage or injury suffered or sustained by an Indemnified
              Person by reason of any acts or omissions arising out of
              their activities on behalf of the Company or in furtherance
              of the interests of the Company, including but not limited to
              any judgment, award, settlement, attorney's fees and other
              costs and expenses incurred in connection with the defense of
              any actual or threatened action, proceeding or claim, if the
              acts or omissions were not a direct result of the gross
              negligence or willful misconduct by the Indemnified Person.

       (b)    GENERAL INDEMNIFICATION BY MEMBERS.  Notwithstanding any
              other provisions contained herein, each Member (the
              "Indemnifying Party") agrees to indemnify and hold harmless
              the other Members, the Company and their respective
              affiliates, agents, officers, directors, partners,
              shareholders and employees, from and against all losses,
              costs, expenses, damages, claims and liabilities (including
              reasonable attorney's fees) as a result of or arising out of
              any material breach of any obligation under this Agreement.
              Recourse for the indemnity obligation of the Members under
              this Section 8.1(b) shall be limited to the amount of the

named as an additional insured under such insurance policies.  The Company 
may purchase and maintain insurance on behalf of any person in such person's 
official capacity against any liability asserted and incurred by such person 
in or arising from that capacity, whether or not the Company would otherwise 
be required to indemnify the person against the liability.

                               ARTICLE IX
                     TRANSFER OF MEMBERSHIP INTEREST
                                       
       9.1    ASSIGNMENT. 

       (a)    GENERAL RESTRICTION ON ASSIGNMENT.   Except as provided in 
              Section 9.1(c) and 9.1(f), no Member may transfer all or a part 
              of such Member's Membership Interest to a non-Member. Transfers 
              of a Member's Membership Interest to another Member shall be 
              effective only if made in accordance with this Section 9.1.

       (b)    ASSIGNMENT OF GOVERNANCE RIGHTS.  Subject to Section 9.2
              herein, a Member's Governance Rights may be assigned to any
              other Member or Affiliated Entity of another Member only if
              (1) the non-transferring Members unanimously approve the
              assignment by written consent, which consent may be granted
              or withheld as the non-transferring Members may determine in
              their sole discretion, (2) the Member seeking to make the
              assignment and the assignee comply with the provisions of
              Section 9.1(d), and (3) the assignment is permitted under the
              terms of the Tolling Agreement. Consent by the
              non-transferring Members to an assignment of Governance
              Rights constitutes the consent necessary to avoid dissolution
              of the Company which would otherwise occur under the Act on
              account of the assignor ceasing to be a Member in the
              Company.

       (c)    ASSIGNMENT OF FINANCIAL RIGHTS.  Subject to compliance with the 
              provisions of Section 9.1(d) hereof, a Member's Financial 
              Rights may be assigned, in whole or in part, to another Person 
              without the consent of the Board of Managers or any other 
              Member.

       (d)    CONDITIONS PRECEDENT TO ASSIGNMENT OF GOVERNANCE RIGHTS OR 
              FINANCIAL RIGHTS TO MEMBERS.  Subject to Section 9.2 herein, 
              any Member desiring to assign such Member's Governance Rights 
              or Financial Rights shall notify the Board of Managers of such 
              desire. Such notice to the Board of Managers shall include (i) 
              an opinion of counsel (whose fees and expenses shall be borne 
              by such assigning Member), reasonably satisfactory in form and 
              substance to the Board, to the effect that either (1) the 
              assignment constitutes an exempt transaction, and does not 

<PAGE>

              require registration under applicable state and federal 
              securities laws, or (2) the Governance Rights or Financial 
              Rights to be assigned are duly and properly registered under 
              all applicable state and federal securities laws; (ii) evidence 
              satisfactory to the Board that such assignment  of Governance 
              Rights is permitted under Section 9.1(b) hereof, and of such 
              assignee's agreement to comply with the terms of this Agreement 
              and to execute any and all documents that the Board may deem 
              reasonably necessary in connection with such assignee becoming 
              a Member; (iii) representations in form and substance 
              reasonably satisfactory to the Board that assignee is acquiring 
              the Governance Rights or Financial Rights for such assignee's 
              own account for investment and not with a view towards the 
              distribution thereof; provided, however, that the disposition 
              of the Governance Rights or Financial Rights shall at times be 
              and remain within the control of such assignee; and (iv) a 
              written agreement signed by the assignee that the Governance 
              Rights or Financial Rights being acquired will in no event be 
              resold unless properly registered under all applicable state 
              and securities laws or exempt therefrom.

       (e)    EFFECTIVE DATE OF ASSIGNMENT.  Any assignment of all or a
              part of a Member's Membership Interest in the Company shall
              be deemed effective on the first day of the month next
              following the month in which the assignment occurs and the
              assignee's name and address and the nature and extent of the
              assignment are reflected in the Required Records of the
              Company. The appropriate Company records shall be
              conspicuously noted to prevent the sale or assignment of
              Membership Interests otherwise than in accordance with this
              Article IX.

       (f)    PLEDGE AND ASSIGNMENT.   Notwithstanding anything to the
              contrary in this Section 9.1, any Member may pledge, assign
              or hypothecate its Membership Interest hereunder to secure
              the payment of any debt incurred by the Company and/or the
              performance of any obligations of the Company.

       9.2    RIGHTS TO PURCHASE AND SELL MEMBERSHIP INTERESTS.

       (a)    ACSC RIGHT TO BUY-OUT OTHER MEMBERS. ACSC shall have the
              right to buy-out the Membership Interest of any other Member
              at any time by giving written notice of its intention to do
              so to the other Member. The buy-out price for each Membership
              Interest purchased pursuant to this Section shall be a sum
              equal to the aggregate Capital Contributions made to the
              Company by the selling Member, plus any unpaid Distributions
              required pursuant to Section 4.2 accrued through the date of
              purchase, plus, if the purchase occurs prior to final
              maturity of the Notes, an amount equal the Make-Whole Amount
              determined as if the Called Principal were the amount of such
              capital contributions and the Remaining Average Life were the
              number of years remaining to the final maturity date of the
              Notes.

<PAGE>

       (b)    NEWCOURT RIGHT TO SELL MEMBERSHIP INTEREST TO ACSC.  Upon
              prior written notice to ACSC, Newcourt shall have the right
              to compel ACSC to purchase Newcourt's  Membership Interest
              (i) at any time after the Notes are paid, (ii) at any time
              upon maturity of the Notes, (iii) upon the purchase of all or
              substantially all of the assets of the Company by ACSC, prior
              to the effective date of such purchase, or (iv) upon the
              merger or consolidation of the Company with or into ACSC,
              prior to the effective date of such merger or consolidation.
              The price for such Membership Interest shall be equal to the
              aggregate Capital Contributions made to the Company by
              Newcourt plus any unpaid Distributions required pursuant to
              Section 4.2 accrued through the date of purchase.

       (c)    NOTICE; TIMING; PAYMENT.  Any purchase by ACSC of a
              Membership Interest pursuant to this Section shall be made by
              payment of immediately available funds by wire transfer in US
              Dollars to the selling Member (to an account specified in
              writing by such selling Member to ACSC) on a date which is
              thirty (30) days after the date of the notice from ACSC to
              the selling Member or from Newcourt to ACSC, as applicable,
              or on such earlier date as may be agreeable to both ACSC and
              the selling Member.  At the time of such payment, the parties
              shall deliver to each other such transfer instruments and
              other documents as may be reasonably requested by either
              party.

       9.3    ACQUIT COMPANY.   In the absence of written notice to the 
Company of any assignment of a Membership Interest, any payment by the 
Company to the assigning Member (or the assigning Member's successor in 
interest) shall acquit the Company of liability to the extent of such payment 
to any other Person who may have any interest in such payment by reason of an 
assignment by the Member, whether by actual assignment or operation of law.

       9.4    RESTRICTION ON TRANSFER.   Notwithstanding the foregoing 
provisions of this Article IX, no assignment or other transfer of a 
Membership Interest may be made if the Membership Interest sought to be 
assigned or transferred, when added to the total of all other Membership 
Interests assigned or transferred within the period of twelve (12) 
consecutive months prior thereto, would result in the termination of the 
Company under Section 708 of the Code; provided, however, that the Board of 
Managers may waive such restriction on transfer and such restriction shall 
not apply in the case of a transfer pursuant to Section 9.1(f) herein.

                               DISSOLUTION

       10.1   DISSOLUTION.  The Company shall be dissolved only upon the 
written agreement of all the Members. As further provided in Section 10.5 of 
this Article, the termination of a 

<PAGE>

Member's membership in the Company shall not cause the dissolution of the 
Company, so long as the Company has the minimum number of members required 
under the Act within ninety (90) days of the termination of a former member.

       10.2   WINDING UP OF BUSINESS.   Upon the occurrence of an event of 
dissolution specified in Section 10.1, the Company shall cease to carry on 
its business, except insofar as may be necessary for the winding up of its 
business, but its separate existence shall continue until a certificate of 
cancellation has been filed with the Delaware Secretary of State's Office or 
until a decree dissolving the Company has been entered by a court of 
competent jurisdiction.

       10.3   DISTRIBUTIONS UPON LIQUIDATION.   Upon liquidation, the 
business of the Company shall be wound up, the Board of Managers shall take 
full account of the Company's assets and liabilities, and all assets shall be 
liquidated as promptly as is consistent with obtaining the fair market value 
thereof. If any assets are not sold, any gain or loss shall be allocated to 
Members in accordance with Article IV as if such assets had been sold at 
their fair market value at the time of the liquidation. If any assets are 
distributed to a Member rather than sold, the Distribution shall be treated 
as a Distribution equal to the fair market value of the assets at the time of 
the liquidation. The assets of the Company shall be applied and distributed 
in the following order and priority:

       (a)    FIRST, to the payment of all debts and liabilities of the
              Company, including all sums due the Managers, and including
              any loans or advances that may have been made by the Members
              to the Company;

       (b)    SECOND, to the establishment of any reserves deemed necessary
              by the Board of Managers or the Person winding up the affairs
              of the Company for any contingent liabilities or obligations
              of the Company in the order of priority set forth in the Act;

       (c)    THIRD, to Newcourt a  sum equal to the aggregate Capital
              Contributions made to the Company by Newcourt, plus any
              unpaid Distributions required pursuant to Section 4.2 accrued
              through the date of distribution, plus, if the purchase
              occurs prior to final maturity of the Notes, an amount equal
              the Make-Whole Amount determined as if the Called Principal
              were the amount of such capital contributions and the
              Remaining Average Life were the number of years remaining to
              the final maturity date of the Notes;

       (d)    FOURTH, the balance, to ACSC.

       10.4   STATEMENT OF CANCELLATION.   Upon the dissolution and 
completion of the winding up of the Company's affairs, the appropriate 
representative of the Company shall execute a certificate of cancellation 
setting forth the information required under the Act, and shall file same 
with the Delaware Secretary of State's office.

       10.5   TERMINATION OF MEMBERSHIP.

       (a)    CONTINUATION OF THE COMPANY.   The Company shall not be
              dissolved and is not required to be wound up by reason of the
              occurrence of an event that terminates the continued
              membership of a Member in the Company if there is at least
              the minimum number of Members required under the Act.

       (b)    STATUS OF MEMBER WHOSE MEMBERSHIP IS TERMINATED.  The Member
              whose membership has terminated shall lose all Governance
              Rights and will be considered merely an assignee of the
              Financial Rights owned before the termination of such
              Member's membership, subject to subsection (c) of this
              Section 10.5. In such event, Schedule A shall be deemed to be
              appropriately amended to allocate the Voting Interest of the
              Member whose membership is terminated to the remaining
              Members. If dissolution occurs pursuant to Section 10.1, then
              the Member whose continued membership has terminated retains
              all the Governance Rights and Financial Rights owned before
              the termination of the membership and may exercise those
              rights through the winding up and termination of the Company.

       (c)    NO OBLIGATION TO PURCHASE FINANCIAL RIGHTS OF TERMINATED
              MEMBER.   Neither the remaining Members nor the Company shall
              have any obligation to purchase such terminated Member's
              Financial Rights in the Company.

       Any Person who is admitted to the Company as a Member shall be subject 
to and bound by all the provisions of this Agreement as if originally a party 
to this Agreement. Such Person shall execute and acknowledge all documents

of Managers, as the Board of Managers shall deem necessary or advisable to

admitted to be bound by all the terms and provisions of this Agreement. Such 
Person shall pay all reasonable expenses in connection with  such admission 
of a Member, including without limitation legal fees and costs of preparation 
of any amendment to or restatement of this Agreement, if necessary or 
desirable in connection therewith.
