The UniMark Group, Inc. (Nasdaq: UNMG), specialty producer and marketer of citrus and tropical fruit products, announced today that the Company has filed a request for extension for filing of its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2000.

On August 31, 2000 the Company completed the sale to Del Monte Company (NYSE: DLM), of the rights to its Sunfresh® brand, its McAllen, Texas distribution center including certain inventory, other intellectual property and property and equipment associated with the Sunfresh® brand. The Company is still analyzing the impact of this transaction on its consolidated financial position and results of operations. As a result, the Company has been unable to compile all the information needed to be reflected in the September 30, 2000 Form 10-Q in a timely manner without unreasonable effort or expense.

Currently, the Company believes that because of the gain resulting from the Del Monte transaction and a nonrecurring gain resulting from a Mexican tax refund, results of operations for the three months ended September 30, 2000 are anticipated to be more favorable than the net loss for the three months ended September 30, 1999.

The Company currently anticipates the filing of its Form 10-Q for the quarterly period ended September 30, 2000 to occur no later than November 20, 2000.
