Darling International to Acquire National By-Products in Transaction Valued at Approximately $141 Million
Strategic Combination Will Enhance Darling's Operations and Future Growth Prospects

Darling International Inc. the largest publicly traded food processing by-products recycling company in the United States, today announced that its Board of Directors has unanimously approved a definitive purchase agreement to acquire National By-Products, LLC ("NBP"), a leading independent rendering company based in Des Moines, Iowa, for a combination of cash and stock valued at approximately $141 million, subject to certain purchase price adjustments.

Under the terms of the agreement, NBP unit holders will receive $70.5 million in cash and an amount of Darling common shares equal to 20 percent of the company's outstanding common shares on a fully diluted basis upon completion of the transaction. Based upon today's amount of outstanding Darling common shares of 65.3 million on a fully diluted basis, NBP unit holders would receive 16.3 million shares of Darling common stock at closing.

The addition of NBP's 42 facilities located throughout the Midwest will strengthen Darling's operational capabilities and diversify its raw material supply. NBP operates 14 large-scale production facilities which will complement Darling's existing Midwestern locations and provide a platform for additional growth of its Restaurant Services business. On a pro forma basis, the combined company had sales in excess of $500 million in fiscal year 2004. The combined company's nationwide network of facilities will have the scale, industry expertise and management talent to realize improved operating efficiencies and pursue new growth opportunities. As a result, Darling anticipates that the transaction will be accretive between a range of $0.04 and $0.06 per share, excluding synergies, based on its preliminary analysis.

Darling International Chairman and Chief Executive Officer Randall Stuewe said, "We have worked hard and are very excited about the benefits that the strategic combination of our two companies will create. Darling's acquisition of National By-Products represents a major step forward in our strategy to deliver value to our stockholders by growing our revenue, diversifying our raw material supplies and creating a larger platform to grow our restaurant services segment. We are confident that NBP's solid operating performance and similar business model will facilitate a smooth and successful integration and, going forward, will significantly enhance our national footprint. We expect NBP's excellent track record of earnings and cash flow generation, as well as their solid balance sheet, to further enhance our capital structure."

Additional Transaction Terms

In addition to the terms noted above, the purchase agreement also includes a provision for the conditional issuance of additional Darling shares to eligible NBP unit holders on the 13-month anniversary of the transaction closing if the dollar value of the stock component of the consideration is below $70.5 million, based upon the average closing price of Darling shares for the 90 calendar days prior to the anniversary date. Darling anticipates that the transaction, which is subject to customary closing conditions, including the expiration of the Hart-Scott-Rodino waiting period and approval by Darling stockholders and NBP unit holders, will be completed in first half of 2006.

Harris Nesbitt served as financial advisor and Weil, Gotshal & Manges LLP served as legal counsel to Darling.
