Investor Presentation

May 29, 2003

Forward-Looking Statements

A number of the statements in this presentation are forward-looking statements. Except for the historical information contained in this presentation, the statements in this presentation are forward-looking statements that are made pursuant to the “safe harbor” provisions of the Private Securities Litigation Act of 1995. Statements regarding future market prices and margins, future operating results, sugarbeet acreage, operating efficiencies, future government action, cost savings, our liquidity and ability to finance our operations, and other statements that are not historical facts contained in this presentation, are forward-looking statements. Forward-looking statements involve risks, uncertainties and assumptions, including market factors, energy costs, the effect of weather and economic conditions, farm and trade policy, our ability to realize planned cost savings, the available supply of sugar, available quantity and quality of sugarbeets, actual or threatened acts of terrorism or armed hostilities, legislative, administrative and judicial actions and other factors. Forward-looking statements are based on management’s current expectations and beliefs and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. Many of these factors are beyond our ability to control or predict. Management cautions against placing undue reliance on forward-looking statements or projecting any future results based on such statements or present or future earnings levels. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual outcomes may vary materially from those indicated. All forward-looking statements in this presentation are qualified in their entirety by the cautionary statements contained in this section and elsewhere in this presentation and in our Form 10-K for the year ended September 30, 2002, our most recent Form 10-Q reports and our other filings with the SEC. We are under no obligation to (and expressly disclaim any such obligation to) update or alter the forward-looking statements whether as a result of new information, future events or otherwise. This presentation does not constitute an offer of any securities for sale.

Note on EBITDA:

Earnings before interest, taxes, depreciation & amortization (EBITDA) is not a measure of financial performance under generally accepted accounting principles and should not be considered in isolation from or as a substitute for net income or cash flow measures prepared in accordance with generally accepted accounting principles or as a measure of liquidity. Additionally, EBITDA may not be comparable to other similarly titled measures of other companies. We have included EBITDA as a supplemental disclosure because our management believes that it provides useful information regarding our ability to service debt and to fund capital expenditures and provides investors a helpful measure for comparing our operating performance with the performance of other companies that have different financing and capital structures or tax rates. In addition, our bank credit agreement contains covenants depending on EBITDA, adjusted to exclude the effect of certain charges and credits.

Sugar Industry Overview

Cane Sugar—Processing Summary

[GRAHIC]

Sugar cane is harvested and processed into raw sugar at sugar mills near the cane fields

Raw sugar is typically 96.0-99.5% sucrose and can be readily transported in bulk

Raw sugar is not normally fit for human consumption as-is

Refineries further process the raw sugar into a range of finished products

Refining involves melting, clarifying, filtering, boiling and drying the raw sugar to remove impurities

Sugar cane refineries operate year round and can be located near the mills or near the centers of consumption

Drivers of cane sugar manufacturing economics include daily production rate (melt), sucrose refining losses and operating efficiency

[GRAPHIC] 8

Sugar Industry Overview

Beet Processing Summary

[GRAPHIC]

Growers harvest beets and deliver to the factory or receiving station

Beets are perishable—in cold climates they can be piled but in warm climates they are processed immediately

Beet factories are located in the beet growing area

Beets are sliced and processed directly into refined sugar

Drivers of efficient beet operations include:

Beet acreage

Beet tonnage

Beet quality

Sugar recovery from beets

Operating efficiency

Financial Overview

Financial Overview

Historical Perspective

The Company increased its leverage to acquire Savannah Foods (1997) and Diamond Crystal Specialty Foods (1998) when sugar margins were strong.

Following the acquisitions, sugar margins declined due to an oversupply of refined sugar in the market. Depressed margins, huge debt burden, and management challenges resulted in the Chapter 11 filing in early 2001.
