Regi U.S., Inc./Reg Technologies Inc. Release RadMax(TM) Progress Update

VANCOUVER, BRITISH COLUMBIA, Apr 06 (MARKET WIRE) --
REGI U.S., Inc. (OTCBB: RGUS)(FRANKFURT: RGJ) and Reg Technologies Inc.
(TSX VENTURE: RRE)(OTCBB: REGRF) are pleased to release the RadMax(TM)
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(TM) 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(TM) 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(R) design is progressing on schedule as planned. We
are extremely pleased with the expertise that Belcan is contributing to
the robustness of the RadMax(TM) 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(TM)/RadMax(TM) rotary technology used in the revolutionary
design of lightweight and high efficiency engines, compressors and pumps.
The RadMax(TM) 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(TM) 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(TM) diesel engines, compressors and pumps
intended for aviation, automotive, industrial processes and military
applications. For more information, please visit www.regtech.com.
