SHEP Technologies Inc. Commences Prototype Program With Pi Technology.

Business Editors/High-Tech Writers

VANCOUVER, British Columbia--(BUSINESS WIRE)--May 28, 2003

SHEP TECHNOLOGIES INC. (OTCBB: STLOF) (BER: IH3) ("STI" or the "Company"), a Canadian incorporated company with operations headquartered in the UK, is pleased to announce the immediate commencement of its prototype vehicle development program with Pi Technology ("Pi"). Pi Technology, the sister company of Pi Research and the commercial automotive division of Pi Group Limited, is a UK-based global leader in the design and development of automotive electronics, innovative control system technologies and control systems for the alternative fuels market.

Pursuant to the Company's Agreement in Principle with Pi reached in February of 2003, the development project calls for the refinement of STI's Stored Hydraulic Energy Propulsion system ("the SHEP System") and the development and delivery of a working prototype vehicle by early 2004. The vehicle will utilize the latest electronic "by wire" technology in a Jaguar X Type passenger vehicle to produce a demonstration vehicle capable of showcasing the SHEP System and its capabilities.

STI has funded the initial phase of the development project. During this phase, Pi expects to achieve a number of key development milestones including:

-- the choice of the prototype vehicle's engine and electronic

control system;

-- the modeling and simulation of the SHEP System to define

operational control protocols;

-- the refinement of the vehicle's proposed architecture;

-- the 3D mechanical scheming of the SHEP System installation for

the prototype vehicle;

-- completion of an initial safety analysis; and

-- the finalizing of costed proposals for lightweight SHEP System

mechanical hardware and for the brake-by-wire portion of the

project from a selected leading brake supplier.

Under the terms of the contract, Pi will utilize the services of West Surrey Racing ("WSR"), a leading British rapid prototyping and engineering company, in the development of the prototype vehicle. During the preliminary development phase, WSR expects to complete a number of key activities including the creation of detailed mechanical data from the 3D modeling of the SHEP System as installed in the prototype vehicle and the final proposal for mechanical construction of refined SHEP System parts. Dick Bennetts, Managing Director of WSR said today, "WSR is very pleased to have been chosen to add technical and engineering value to this very significant automotive engineering project. We expect to work very closely with Pi on our respective development initiatives during the prototype program to ensure maximum effectiveness for the demonstration of the SHEP System's capabilities."

The refinement of the SHEP System is expected to enhance the technology's already proven efficiencies in fuel consumption, emission reductions and engine maintenance. Ian Redhead, Managing Director of Pi Technology, noted, "Pi Technology is very much looking forward to working with STI on this vehicle development. We can see that the technology has great potential."

The Company will showcase its prototype in a generic passenger platform that, with minor detail refinement, can be applied to a wide range of transportation applications. These include vehicles such as taxis, buses and trains, and the full spectrum of commercial and special-purpose vehicles such as delivery vans, garbage and fire trucks.

"The prototype development project with Pi represents a huge step forward for STI and its technology," said Malcolm Burke, President and CEO of STI. "Pi's unique qualifications and automotive industry relationships will not only provide us with a proprietary Electronic Control System ("ECS"), but will also permit the ECS to be electronically integrated with the latest "by wire" technology, which we believe will be a key element in commanding significant market share in the future. Further, Pi has revolutionary simulation software that can be used model the benefits of the SHEP System to any potential user. We anticipate this will prove invaluable to the Company in the early securing of co-development, manufacturing and licensing opportunities."

About SHEP Technologies Inc.

SHEP Technologies Inc. recently acquired SHEP Limited, a corporation based in the Isle of Man with operations in Taunton, England and in the United States. SHEP Limited has designed and developed proprietary energy technology for application in the global automotive sector.

The SHEP System, using electronics and proprietary hydraulic pump motors, captures otherwise lost kinetic energy generated during vehicle braking, and utilizes this recovered energy for vehicle acceleration during the inefficient low-speed acceleration phase. Under a controlled test environment at one of the world's largest automotive manufactures, significant fuel savings, together with reduced engine and brake wear and tear, were realized.

The SHEP System is intended to be equally applicable to delivery, service and passenger vehicles of all sizes and variety. Optimal use of SHEP technology is anticipated in high density urban traffic environment where acceleration and braking cycles are frequent - accordingly buses, trucks, taxis and subway systems could be ideal applications.

The Company anticipates licensing its "Stored Hydraulic Energy Propulsion" (the "SHEP System") to automotive manufacturers and their Tier 1 suppliers. Hydraulic propulsion is being embraced by OEMs in the automotive industry. In particular, SHEP components are incorporated as an integral part of one of North America's major auto producer's hydraulic power assist-equipped development vehicles, which passed formal 'Proof of Concept' in December 2000 and is now positioned for the 'Implementation Ready' design, development and testing phase.
