                        NOTES TO THE FINANCIAL STATEMENTS
              FOR THE THREE MONTHS ENDED NOVEMBER 30, 1998 AND 1997


NOTE 1:  BASIS OF PRESENTATION

The unaudited financial statements contained herein have been prepared 
pursuant to the rules and regulations of the Security and Exchange 
Commission. Accordingly, they do not include all the information and 
footnotes required by generally accepted accounting principles. However, in 
the opinion of management, all adjustments, consisting of normal recurring 
accruals, considered necessary for a fair presentation have been included.

The operating results for the three month period ended November 30, 1998 are 
not necessarily indicative of the results that may be expected for the year 
ended August 31, 1999.

The amount paid to growers for sugarbeets (beet payment) depends on the 
future selling prices of sugar and by-products as well as processing and 
other costs to be incurred during the remainder of the fiscal year. For the 
purposes of this report, the amount of the beet payment, future revenues and 
costs have been estimated. Therefore, adjustments with respect to these 
estimates may be necessary in the future as additional information becomes 
available.

These financial statements should be read in conjunction with the financial 
statements and notes included in the company's annual report for the year 
ended August 31, 1998.

NOTE 2:  INVENTORIES

         The major components of inventories are as follows (In Thousands):

realizable value. Unprocessed sugarbeets are valued at the estimated net beet

For interim reporting, the Net Proceeds from Member Business is determined 
based on the forecasted beet payment and the percentage of the tons of 
sugarbeets processed to the total estimated tons of sugarbeets to process for 
a given crop year. Accrued continuing costs represents the difference between 
the Net Proceeds from Member Business as determined above and actual member 
business crop year revenues realized and expenses incurred through the end of 
the reporting period. Accrued continuing costs are reflected in the Financial 
Statements as a cost on the Statements of Operations and as a current 
liability on the Balance Sheets.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION
         FOR THE THREE AND THREE MONTHS ENDED NOVEMBER 30, 1998 AND 1997


RESULTS OF OPERATIONS

COMPARISON OF THE THREE MONTHS ENDED NOVEMBER 30, 1998 AND 1997

Revenue for the three months ended November 30, 1998, was $195.7 million, an 
increase of $16.5 million from 1997. Revenue from total sugar sales increased 
8.6 percent reflecting an 11.4 percent increase in hundredweight sold 
partially offset by a 2.5 percent decrease in the average selling price per 
hundredweight. Revenue from pulp sales increased 25.0 percent due to a 82.1 
percent increase in the volume of pulp sold partially offset by a 31.4 
percent decrease in the average selling price per ton. Revenue from molasses 
sales increased 13.3 percent due to a 42.0 percent increase in the volume of 
molasses sold partially offset by a 20.2 percent decrease in the average 
selling price per ton. Revenue from the sales of Concentrated Separated 
By-Produce (CSB), a by-product of the molasses desugarization process, 
decreased 14.6 percent due to a 15.7 percent decrease in the average selling 
price per ton partially offset by a 1.4 percent increase in sales volume.

Cost of product sold, exclusive of payments for sugarbeets, decreased $12.7 
million. Direct processing costs for sugar and pulp increased 2.9 percent. 
Fixed and committed expenses increased 17.3 percent reflecting higher 
maintenance costs. The cost associated with sugar purchased to meet customer 
needs was up $.4 million due to the increase in purchased sugar activity in 
distant geographic markets.

Selling expenses increased $4.9 million due primarily to the increase in the 
volume of products sold. General and Administrative expenses decreased $.3 
million due to a decrease in general administrative costs that consist mainly 
of decreased incentive compensation.

The increase in accrued continuing costs was due primarily to changes in 
sugar sales and production and the differences in the timing of incurring 
processing costs.

Interest expense increased due primarily to higher average borrowing levels 
for short and long-term debt this year.

Non-member activities resulted in a gain of $4.0 million for the three months 
ended November 30, 1998 as compared to a loss of $5.9 million for the same 
period last year. The majority of this gain is related to the sale of beet 
seed assets to Betaseed Inc. (BETA), a wholly owned subsidiary of 
Kleinwanzlebener Saatzucht, Ag.

American Crystal has made extensive efforts to become year 2000 compliant. 
Twenty-two 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.

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 
("Bank"). American Crystal has a short-term line of credit with the Bank in 
1998 of $280 million.

The various loan agreements between the Bank and American Crystal obligate 
American Crystal to maintain or achieve certain amounts of working capital 
and certain financial ratios and impose restrictions on American Crystal. As 
of November 30, 1998, American Crystal was in compliance with its loan 
agreements.

The primary factor for the changes in American Crystal's financial condition 
for the three months ended November 30, 1998 was due to the 1998/1999 
sugarbeet processing campaign. The cash used in operations of $142.3 million 
and investing activities of $14.8 million, was funded through the cash 
provided by financing activities. The net cash provided by financing 
activities was primarily comprised of the net proceeds from short-term debt 
of $124.0 million, proceeds from long-term debt of $40.0 million and proceeds 
from the sale of stock of $3.2 million, partially offset by the payment of 
the unit retains of $10.2 million.

Working capital has increased $28.5 million from $30.4 million at the 
beginning of the year to $58.9 million as of November 30, 1998 primarily due 
to increased inventories, partially offset by increased short term and 
current maturities of long term debt. Working capital for the three months 
ended November 30, 1998 was $58.9 million, a decrease of $18.5 million 
compared to $77.4 million in the same period in 1997.

Capital expenditures for the three months ended November 30, 1998 were $11.4 
million.

American Crystal anticipates that the funds necessary for the Bank's working 
capital requirements and future capital expenditures will be derived from 
depreciation, unit retains and long-term borrowing.

The growth in the market for refined sugar in the late 1980's and the mid 
1990's is a reversal of trends in the 1970's and early 1980's which resulted 
in a reduced market for refined sugar. During the 1970's and early 1980's, 
high fructose corn syrup was increasingly used as a replacement for refined 
sugar in certain food products. (The prime example of this trend was the use 
of high fructose corn syrup in beverages such as soft drinks.) In addition, 
non-nutritive sweeteners such as aspartame were developed and used in food 
products. While high fructose corn syrup and non-nutritive sweeteners 
constitute a large portion of the overall sweetener market, the Company 
believes that the recent trend of increased use of refined sugar results from 
population growth and, more importantly, increased acceptance of the use of 
sugar as a desirable natural ingredient in a normal diet.

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

American Crystal is subject to various lawsuits and claims which arise in the 
ordinary course of its business. While the results of such litigation and 
claims cannot be predicted with certainty, management believes the 
disposition of all such proceedings, individually or in the aggregate, should 
not have a material adverse effect on the Company's financial position, 
results of operations or cash flows. Management is not aware of any 
threatened claims which could result in the commencement of legal proceedings.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

At the Hillsboro Factory District Meeting on November 9, 1998, an election of 
a Board of Director was held. Court Hanson who sought re-election received 91

the first ballot. Jim Ross received 66 of the 105 votes cast in the runoff 
election. His three-year term expires in December, 2001. Mr. Ross replaces 
Barry Malme who was unable to stand for re-election due to the provisions of
