NEWS RELEASE

REGI U.S., Inc. (“REGI” or “RGUS”)

Reg Technologies Inc. (“Reg” or “RRE.V” or “REGRF”)

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

RADMAX™ FABRICATION PURCHASE ORDER HAS BEEN

ISSUED TO PATH TECHNOLOGIES

For Immediate Release: February 3, 2011. 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 announce they have paid Path

Technologies for the purchase order to commence fabrication to complete the cam and

actuator for the RadMax™ demonstration diesel engine model. The original commencement

date was announced in our August 12, 2010 news release, which stated that the schedule

target date for completion of the prototype fabrication and for starting initial testing was to be

completed before the 2010 year end. Due to a dispute with Reg Technologies Inc.'s

Silverknife property (announced August 27, 2010), the proposed plan for financing was

delayed until this matter was resolved, which resolution was announced on December 21,

2010.

The financing for Reg Technologies Inc. was announced shortly after the holidays on

January 5, 2011. Subsequently, US$74,000 was advanced to Path Technologies to

complete the rotor and actuator.

The time frame to fabricate the RadMax™ demonstration diesel engine model and to

commence initial testing is estimated to take approximately 180 days.

Robert Grisar, Vice President of Engineering for REGI U.S., Inc., has provided 3D solid

models and 2D PDF drawings of the cam and actuator, which are the first components to be

fabricated.

Robert Grisar, states, "After several years of review by our engineering team, the new

RadMax™ rotary design is now ready to be built with a high degree of confidence".

The benefits of the RadMax™ diesel engine design have been reported by Dr. Allen

MacKnight (former Honeywell Corporate Fellow) as follows:

• More fuel efficient due to its utilization of diesel fuel in comparison to gasoline

• Lighter weight compared to a piston engine with the same power

• A reduction of emission due to the lighter weight engine

• See Reg Technologies Inc. web site www.regtech.com and REGI U.S., Inc. web site

www.regiinc.com for addition information and benefits.

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. For more information, please visit
