| Groen Brothers Aviation Receives Three Year $50 Million Equity Financing Commitment
 
 SALT LAKE CITY, May 3, 2001 (BUSINESS WIRE) -- Groen Brothers Aviation Inc. (OTC
 BB: GNBA) Thursday announced that it has received a binding commitment from an
 institutional investor to provide up to $50 million in equity financing.
 
 Groen Brothers Aviation (GBA) is the developer and manufacturer of the Hawk 4
 Gyroplane. The Hawk 4 is a four passenger, near vertical take-off and landing
 aircraft that is powered by a Rolls-Royce model 250 gas turbine engine. The Hawk
 4 is a new alternative to helicopters with many advantages, not the least of
 which are safety and low operating cost.
 
 Over the next three years, Groen Brothers Aviation Inc. (GBA) will have the
 right to obtain as much as $50 million through the issuance of common stock to
 the institutional investor in a series of periodic draw-downs. The timing,
 dollar amount, and minimum price per share of each draw-down, are at the sole
 discretion of GBA, subject to certain contractual provisions which include
 volume and price limitations.
 
 This commitment is subject to the effectiveness of a registration statement to
 be filed with the Securities and Exchange Commission covering the resale of the
 shares covered by the equity line and certain related warrants.
 
 "The advantage of this type of financing is that we can sell our shares during
 periods of strength in the market price of our stock, thereby enabling the
 company to minimize dilution while raising capital," said David Groen, president
 and chief executive officer of Groen Brothers Aviation Inc.
 
 "Over the next three years we expect to sell our shares at ever increasing
 prices, to meet our financial needs."
 
 Groen continued, "The process of developing a new, FAA Type Certified aircraft
 and bringing it into the market place, is a large puzzle with many complex
 pieces necessary to complete the picture. The final piece for us is sufficient
 funding. We believe that this funding package is that final piece.
 
 "We already have in place the other necessary pieces to this puzzle: design,
 engineering, drafting and modeling; manufacturing, manufacturing engineering and
 tooling design; quality assurance and product support; sales, marketing and
 public relations; and a highly competent and experienced administrative and
 management staff.
 
 "Our production tooling is already built and paid for. Our aircraft is
 performing marvelously and routinely. It impresses everyone who sees it fly. In
 short, we have the right team, at the right place and at the right time, with
 the right product. And now, the right funding," said Groen.
 
 Groen Brothers Aviation is developing modern gyroplanes for the commercial
 world. In the last 10 years, GBA has flown several models of its gyroplane line
 including proof of concept aircraft, technology demonstrators, and production
 prototypes. Each month the company performs a flight demonstration of its Hawk 4
 Gyroplane at either its Arizona facility near Phoenix or at a national venue.
 
 These flight demonstrations are attended by GBA shareholders, the public, and
 prospective customers. Most recently the company's Hawk Gyroplane flew at the
 Hiller Aviation Museum in California and at the EAA "Sun 'n Fun" air show in
 Florida.
 
 GBA is well into the process of FAA Type Certification of the Hawk 4 Gyroplane
 and has a nationwide dealership network that has brought to the company cash
 deposits on more than 140 aircraft.
 
 GBA is fully reporting and publicly traded on the OTC Bulletin Board, stock
 symbol (GNBA). For additional information, access GBA's Web page at:

 These include statements relating to the amount of money that may be drawn under
 the financing agreements and the number of shares of common stock that the

 Such statements are subject to substantial risks and uncertainties, including
 (i) the risk that low dollar trading volume in the company's stock during the
 three year draw-down period will affect the size of individual and aggregate

 and its need for additional financing might compel it to engage in highly
 dilutive draw-downs; (iii) the risk that the company is unable to meet
 particular conditions for draw-downs, including, without limitation, the
 registration of the stock to be sold in a draw-down and shareholder approval for
 certain levels of dilution.
 
 Actual results, events or performance could differ materially from any future
 performance suggested above.
 
 Factors that might cause such a difference include, but are not limited to,
 market conditions and the availability of separate third-party financing that
 could impact the company's ability to control any dilutive impact, and its
 ability to remain in compliance with the terms of the equity financing line, as
 well as other risk factors described in its filings with the SEC.

 plans; product performance; risks associated with regulatory certifications of
 the company's commercial aircraft by United States and foreign governments;
 other regulatory uncertainties; collective bargaining labor disputes;
 performance issues with key suppliers and subcontractors; governmental export
 and import policies; and the ability to adequately finance operations to the
 date of FAA certification and manufacturing.
