REGI U.S., Inc. (OTCBB: RGUS)(FRANKFURT: RGJ) ("REGI" or "RGUS") and Reg Technologies Inc. (TSX VENTURE: RRE)(OTCBB: REGRF) ("Reg" or "RRE.V" or "REGRF") are pleased to provide the second fabrication progress report for the prototype RadMax™ Diesel Engine.

We estimate that approximately one-third of all fabrication work is complete, resulting in us being ahead of schedule and under budget.

As of the date of this release, the fabrication progress is as follows:

--  The Rotors have completed their first-pass rough turning process within
    .030-inch of final. As of this report, the following Rotor fabrication
    operations have been completed: Outer surface, Neck, Driveshaft Slot,
    and Combustion Chamber.
--  The Cams have completed their initial rough turning passes. The reason
    for the two-pass turning process is because the metal "moves" (stretches
    or deforms) after the machining process. To maintain our high-tolerance
    requirements, the two-passes are required.
--  Fabrication of the 24 Vane-Actuator assemblies is complete. This
    includes completion of the Vanes, Connecting Tubes, Axles, Wheels, Wrist
    Pins, and integration with commercial wheel bearings.

Steps in detail of our work leading to RadMax™ test and certification were presented in our March 8, 2011 news release.

A picture of the rotor fabrication progress and new machining center is available on the Companies' websites at www.regtech.com (Reg Technologies Inc.) and www.regiinc.com (REGI U.S., Inc.). The following are direct links:

Robert Grisar, Vice President of Engineering for REGI U.S., Inc. said, "The recent award of the RadMax™ patent by the USPTO has energized all of our fabrication subcontractors. The unique parts are evolving quickly. The close coordination and frequent reviews ensure all critical dimensions and tolerances are achieved, on schedule and within planned cost."

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.
