DONLAR CORPORATION ANNOUNCES FIRST QUARTER 2003 RESULTS BEDFORD PARK, IL -- (JUNE 16, 2003) -- DONLAR CORPORATION (OTC:DLRC) (the surviving corporation of the merger between the Company and Donlar Biosyntrex Corporation), a world leader in green chemistry, products and technology, today announced that the Company reports revenue of approximately $1 million for the first quarter ended March 31, 2003, up 23% from revenue reported for the first quarter of 2002. The Company reports revenue for the first quarter of 2003 of $1,082,115 compared to $877,684 for the first quarter of 2002, an increase of approximately 23%. The Company continues to see its main revenue growth in the oil field services industry and has developed strong sales in the agricultural market. The Company reports a net loss in the first quarter of 2003 of approximately $4.4 million, compared to a net loss of $3.7 million for the first quarter of 2002. The increase in net loss was primarily attributable to expenses relating to the merger of Donlar Corporation and Donlar Biosyntrex Corporation and the conversion of debt. Losses from operations for this period decreased from $891,695 for the first quarter of 2002 to $501,447 for the current quarter. Larry Koskan, President and CEO of Donlar, stated: "We have started off the 2003 fiscal year with a million dollar quarter and expect to show continued growth in our sales throughout the year. 2003 started with the merger of Donlar and its majority owned subsidiary, Donlar Biosyntrex Corporation. This merger allows us to better control our expenses and operating costs, giving our shareholders better investment value. As we look to our future, we continue to be very aware of our business plan targets especially with respect to overall revenues and expense control. We continue to see growth in all of our business areas as demand for our products increase. We have also recently retained Lincoln Partners, LLC, an investment banker, to provide advice concerning strategic alternatives for Donlar, particularly with respect to obligations to our only lender."
