REGI U.S., INC. / REG TECHNOLOGIES INC. RELEASE RADMAX™

PROGRESS UPDATE

For Immediate Release: March 31, 2010. Vancouver, BC – REGI U.S., Inc. (OTC BB: RGUS,

Frankfurt Stock Exchange: RGJ) and Reg Technologies Inc. (TSX Venture Exchange: RRE.V,

OTC BB: REGRF) are pleased to release the RadMax™ Diesel Engine Design progress

update.

Phase 1: Conceptual Design, and Phase 2: Preliminary Design are now complete. We are now

executing Phase 3: Detail Design.

As previously described in our November 13, 2009 Press Release, we are nearing the

completion of a significant milestone of the Belcan Engineering review of the prototype engine

design, which was estimated at 6 months.

The actions completed are as follows:

• Retain Belcan as an independent engineering analysis organization to provide

independent validation of all RadMax™ design elements: functions, tolerances, and

material selections

• Verify environmental conditions (temperatures, pressures, centrifugal forces, etc.)

Actions that are continuing include:

• Identify components that require detail stress analysis

• Perform complete integration of all components and evaluate their performance and

strength under non- operating and operating conditions.

We have conducted a technical engineering interchange meeting with Belcan for the

thermodynamics analysis portion. A final report has been jointly prepared and submitted to the

Fortune 1000 company for review. A mutli-company thermodynamics review is planned for mid

April.

The thermodynamics report includes recommendations for RadMax™ Engine materials,

thicknesses, tolerances, and coatings. One specific recommendation is to fabricate the cam

using lighter weight materials to take advantage of its improved thermal conductivity.

Near-term program milestones include:

• Completion of Belcan Engineering review of mechanical components, bearings, and

lubrication – approx. 3 additional months

• Review and Approval by the Fortune 1000 Company – approx. 30 days

• Fabrication of the prototype engine – approx. 3 months

• Initial prototype testing – approx. 3 months

Robert Grisar, Vice President of Engineering, reports, “The Belcan review of the RadMax®

design is progressing on schedule as planned. We are extremely pleased with the expertise that

Belcan is contributing to the robustness of the RadMax™ design.

ABOUT REGI U.S., INC. AND REG TECHNOLOGIES INC.

Reg Technologies Inc. and REGI U.S., Inc. are developing for commercialization an improved

axial vane type rotary engine known as the Rand Cam™/RadMax™ rotary technology used in

the revolutionary design of lightweight and high efficiency engines, compressors and pumps.

The RadMax™ engine has only two unique moving parts, the vanes (up to 12) and the rotor,

compared to the 40 moving parts in a simple four-cylinder piston engine. This innovative

design makes it possible to produce up to 24 continuous power impulses per one rotation that is

vibration-free and extremely quiet. The RadMax™ engine also has multi-fuel capabilities

allowing it to operate on fuels including gasoline, natural gas, hydrogen, propane and diesel.

REGI U.S., Inc. and its parent company, Reg Technologies Inc., are currently designing and

testing prototype RadMax™ diesel engines, compressors and pumps intended for aviation,

automotive, industrial processes and military applications. For more information, please visit
