TISOREX Completes Acquisition of Facilities for Production of Bulk Paclitaxel from Hauser


FORT LEE, N.J., March 14, 2002 (PRIMEZONE) -- TISOREX, Inc. announced today that it has acquired from Hauser, Inc. (OTCBB:HAUS) of Boulder, Colorado, paclitaxel processing equipment and licensed intellectual property on undisclosed terms.

In a separate agreement, TISOREX agreed to lease Hauser's former Boulder facility where the paclitaxel manufacturing equipment is located. When operational, the Boulder facility and equipment produced in excess of 100 kilograms of cGMP pharmaceutical grade paclitaxel per year.

TISOREX, a privately-held Delaware corporation, and its affiliate NatEx Georgia LLC (together the "Company"), are implementing plans to become the world's leading vertically integrated supplier of FDA approved generic paclitaxel (the active ingredient in Taxol(r)), its natural precursors and related bulk APIs.

Paclitaxel is the active ingredient in the world's top-selling anti-cancer drug, Taxol(r), which generated $1.7 billion in sales in 2000.

The transaction with Hauser coincides with the imminent commissioning by NatEx Georgia LLC of a taxane biomass processing facility in the Republic of Georgia as a raw material source for the Company's paclitaxel facility in Boulder. Through NatEx Georgia LLC, TISOREX, intends to produce natural paclitaxel using a ten-year license to harvest Georgian yew tree (Taxus baccata) clippings, a low-cost, high-yielding, renewable and previously untapped source of paclitaxel.

Under the terms of these agreements, TISOREX receives a facility for the production of paclitaxel which includes:


 (a) formerly cGMP compliant facility of approximately 32,500 square
    feet at which Hauser  produced paclitaxel;

 (b) paclitaxel processing equipment and utilities to produce
     paclitaxel and other taxoids from yew tree extracts that was
     formerly used in the production of paclitaxel in accordance with
     U.S. regulatory requirements (cGMP);

 (c) license for technologies for isolating and purifying paclitaxel
     from biomass.  These technologies include extraction, isolation,
     and purification, as well as high recovery crystallization
     technology;

 (d) Hauser will also provide TISOREX consulting and technical
     personnel to support and assist in the scale-up of building the
     paclitaxel production facility.

In addition, joining TISOREX is Dr. Dean Stull, the former Chairman and CEO of Hauser Inc. Dr. Dean Stull founded Hauser in 1983 and during the next 18 years, he served Hauser as Chairman and Chief Executive Officer (1983-1999) and as Senior Executive Vice President, Technology of the Company (2000-2001). Dr. Stull has a Ph.D. in Physical Organic Chemistry (1976) from the University of Colorado (Boulder).

"We are delighted to have someone with Dr. Stull's experience working with the TISOREX team. Dr. Stull's experience at starting up a paclitaxel facility, his background in chemistry, his many years of operating experience in the pharmaceuticals supply industry and his contacts within the paclitaxel world represent a substantial asset to our company," said Vasili Patarkalishvili, Chairman and Chief Executive officer of TISOREX.

Commenting on the agreement, Mr. Patarkalishvili said, "We believe that our Boulder, Colorado facility, with its existing technical equipment, intellectual property and experienced management, will now enable TISOREX to be the leading producer of bulk paclitaxel."
