Item 1.01 Entry Into a Material Definitive Agreement

Extension of Maturity Dates

During 2006 and 2007, Groen Brothers Aviation, Inc. (the “Company”) obtained debt financing from certain holders of the Company’s Series B Preferred Stock (the “Series B Holders”) in the aggregate principal amount of $4,400,000 (the “2006/2007 Notes”). The 2006/2007 Notes provide for the payment of simple interest at the rate of 36% per annum. The maturity date for the 2006/2007 Notes has been extended from time to time, and on December 19, 2011, the Company and the Series B Holders entered into amendments to extend the maturity date from October 31, 2011 to January 31, 2012, which amendments were dated effective as of October 30, 2011.

The Series B Holders have agreed to extend the redemption date of the Series B Preferred Stock from time to time, and on December 19, 2011, the Company and the Series B Holders agreed to extend the redemption date from October 31, 2011 to January 31, 2012, or such later date as agreed to in writing by at least 80% of the Series B Holders, which amendment was dated effective as of October 30, 2011.

In October 2008, as part of a Note Purchase Agreement between the Company and certain Series B Holders as lenders named on the signature page thereto (the “Lenders”), the Company issued short-term interest bearing notes in the principal amount of $36,962,000 in satisfaction of the accrued and unpaid dividends on the Series B Preferred Stock through October 9, 2008 (the “Dividend Notes”). Because the Company had paid such dividends in kind by issuing additional shares of Series B Preferred Stock, the issuance of the Dividend Notes resulted in the redemption of $36,962,000 of Series B Preferred Stock. The Dividend Notes provide for the payment of interest at the rate of 15% per annum, compounded quarterly. The maturity date for the Dividend Notes has been extended from time to time, and on December 19, 2011, the Company and the Lenders entered into amendments to extend the maturity date from October 31, 2011 to January 31, 2012, which amendments were dated effective as of October 30, 2011.

The Note Purchase Agreement, as amended, provides for the periodic sale by the Company to the lenders of short-term promissory notes in the aggregate principal amount of up to $12,750,000 to provide the Company with operating capital, as specified in the draw requests for such notes (the “Note Purchase Notes”). The draw requests must be approved by the Lenders. The maturity date for the Note Purchase Notes has been extended from time to time, and on December 19, 2011, the Company and the Lenders entered into amendments to extend the maturity date from October 31, 2011 to January 31, 2012, which amendments were dated effective as October 30, 2011.

On December 19, 2011, the Company filed the Fifteenth Amendment to the Fifth Restated Articles, which extended the mandatory redemption date of the Series B Preferred Stock from October 31, 2011 to January 31, 2012, or such later date as agreed to in writing by the holders of at least 80% of the outstanding shares of Series B Preferred. The amendment was dated effective as of October 30, 2011.

2On January 24, 2012, the Company filed the Sixteenth Amendment to the Fifth Restated Articles, which extended the expiration date of the Company’s Series A Preferred Stock from January 31, 2012 to January 31, 2013. The amendment was dated effective as of January 30, 2012.
