Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Basis of Presentation

Organization and Consolidation

The unaudited condensed consolidated financial statements include the accounts of Groen Brothers Aviation, Inc. (the “Company”) and its wholly owned subsidiary, Groen Brothers Aviation USA, Inc. (“GBA USA”), and include all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary to present fairly the financial position as of ~~September~~December 3031, 2011 and the results of operations and cash flows for the three months and six months ended ~~September~~December 3031, 2011 and 2010. The results of operations for the three months and six months ended ~~September~~December 3031, 2011 are not necessarily indicative of the results to be expected for the full fiscal year ending June 30, 2012.

Basis of Presentation and Going Concern Uncertainty

The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. Because of the lack of significant operating revenues, recurring operating losses, negative cash flows from operations, the excess of current liabilities over current assets, significant past due obligations, and the stockholders’ deficit, there is substantial doubt about the Company’s ability to continue as a going concern.

At ~~September~~December 3031, 2011, we had total current liabilities of $~~163~~169,~~234~~396,000 and current assets of $~~244~~66,000, resulting in a working capital deficiency of $~~162~~169,~~990~~330,000. At ~~September~~December 3031, 2011, we had a total stockholders’ deficit of $~~171~~178,~~633~~073,000.

The Company has ceased production of the SparrowHawk, and currently is seeking to transfer the SparrowHawk and its technology to a joint venture (“JV”) to produce fully-assembled light gyroplanes. Groen Brothers Aviation International, LLC, (“GBA LLC”) a wholly owned special purpose subsidiary of the Company, and Guangzhou Suntrans Aviation Science and Technology Co., Ltd. (“Suntrans”), a company incorporated under the laws of the People’s Republic of China (“PRC”), entered into a Cooperative Joint Venture Contract (the “Agreement”) dated effective as of November 14, 2010 that provides for the establishment of Foshan Suntrans-Groen Aviation Co., Ltd. (the “Joint Venture”) to assemble, manufacture, sell and provide related services for the Company’s SparrowHawk Gyroplane Program, including the most advanced version of the SparrowHawk aircraft developed to date, the SparrowHawk III.

The Joint Venture Agreement provides that it will only come into force upon approval by the Chinese Examination and Approval Authority (“CEAA”) in accordance with applicable law and if such approval is not granted, the Agreement shall be null and void. Further, Ifif such approval has not been obtained and a Business License for the Joint Venture issued within 180 days of the date of signature of the Agreement, the parties shall jointly consult to determine whether to continue with the formation of the Joint Venture and, if after a period of 30 days the parties cannot agree upon a common action to be taken, then either party shall have the option to deem the Agreement void and of no effect by giving written notice to the other party. The 180 day period from date of signature was reached on May 14, 2011 and the 30 day period on June 13,~~2001~~ 2011, and as of the submission of this Report, the Company had not received any confirmation that the Business License had been issued. As a result, both parties are free to initiate steps that could lead to abrogation of the agreement. Although as of the date hereof, neither party has chosen to take any such step, we can give no assurance that the parties will obtain approval from the CEAA to establish the Joint Venture or that the implementation will ever take place.

The gyroplane technology capabilities of the Company, through the use of advanced software applied to the versatility of composite materials for rotorcraft, have led to the initial design by the Company of a new six passenger seat (plus pilot) aircraft, preliminarily named the Hawk 6, and now renamed the ArrowHawk. The Company believes this gyroplane aircraft extends and enlarges the commercial market potential of the Company’s smaller four-passenger Hawk 4 gyroplane, previously manufactured as a pre-production aircraft and currently flying for concept demonstration purposes to parties interested in the ArrowHawk. We believe that the ArrowHawk can offer economic and performance advantages over competitive aircraft types for such applications as tour operations and pipe/power line patrol. AsIn ofparallel with the ~~date of this Report~~ArrowHawk, the Company ishas ~~seeking~~undertaken ~~funding to finalize~~ the initial design ~~and certification~~ of ~~the~~a ~~ArrowHawk~~smaller ~~for~~two-seat ~~commercial~~gyroplane, ~~production~~named ~~and~~the ~~for~~ShadowHawk, ~~this~~using ~~purpose~~comparable ~~exhibited~~technology ato ~~full~~that ~~scale model~~ of the ArrowHawk atand ~~the~~intended ~~China~~for ~~International~~aerial ~~Aviation~~observation &for ~~Aerospace~~both ~~Exhibition~~commercial inand ~~November~~public ~~2010~~agency usage.

InAs ~~October,~~of ~~2010~~the date of this Report, ~~shortly~~the Company is seeking funding to finalize the design and certification of both the ArrowHawk and ShadowHawk for commercial production. For this purpose the Company exhibited a full scale model of the ArrowHawk at the China International Aviation & Aerospace Exhibition in November 2010. Shortly prior to the Exhibition, in October 2010, the Chinese State Council, Central Military Commission, approved the “low-altitude airspace management reform guidance” that ~~indicates~~indicated an impending relaxation of regulations limiting the use of private and other commercial aircraft in China. We believe that as a result, business interest in the development of commercial flight industry in China has been significantly stimulated. ~~The~~In this environment the Company’s exhibit of the ArrowHawk inat China’s inmajor ~~November,~~Airshow ~~2010,~~ attracted substantial notice ~~in this environment~~, including an invitation for Mr. David Groen to be a keynote speaker at the “China International General Aviation Summit” in Shanghai in April 2011. This Conference, held in association with the Civil Aviation Administration of China (“CAAC”), dealt directly with “Opportunities and Challenges under China’s low-Altitude Airspace”.” WeThe ~~believe~~positive response to Mr. Groen’s address to the Conference on the utility of runway-independent gyroplanes tohas encouraged our belief that gyroplanes such as the ArrowHawk, ShadowHawk, and SparrowHawk can take advantage of ~~those~~the ~~opportunities~~new ~~was~~Chinese ~~well received~~regulations.

In this context, several Chinese parties ~~have~~ subsequently approached the Company to explore an interest in cooperation in the development of the Company’s ArrowHawk, ShadowHawk and other advanced gyroplane and gyrodyne products for commercial use. The Company ~~has~~ held meetings with two such parties and, ~~subsequent~~in toeach ~~the~~case ~~end~~in of2011, ~~the~~as ~~third~~previously ~~Quarter~~reported, ~~in each case~~ signed a non-binding Memorandum of Understanding (or equivalent agreement) (hereafter “MOU”) ~~for~~with those parties.

There can be no assurance that these MOUs, as contemplated or expanded, or any other activities will enable the Company to be successful in obtaining the necessary funding for its gyroplane programs.

The Company has completed work on Phase I of a contract with the U.S. Defense Advanced Research Projects Agency (“DARPA”) where it served as prime contractor to design a proof of concept high speed, long range, vertical takeoff and landing aircraft. This modern rotorcraft, named the “Heliplane” by DARPA, is an intended demonstration vehicle for future gyrodynes to be used in combat search and rescue roles. The Company was subsequently engaged by Georgia Institute of Technology (“GT”) as a subcontractor for rotor system work for Phase IB of the DARPA contract, with final payment received from GT in September 2009. As of the date of this report, DARPA has not yet announced funding for Phase II and the future involvement of the Company in the DARPA contract is not anticipated.

As noted in our Form 10-K for the fiscal year ended June 30, 2011, the Company is a member of the Vertical lift Consortium (“VLC”) established by the Department of Defense to provide opportunities for small VTOL research and development companies to develop VTOL platforms. The Company continues to advocate its Heliplane technology through the VLC and other avenues, but there is no assurance that these efforts will be successful.

The Company’s continuation as a going concern is dependent on attaining profitable operations, obtaining additional outside financing and/or restructuring its debt obligations, including its Series B Preferred Stock. During the past ~~two~~three fiscal years, we have funded losses from operations primarily from the issuance of debt to related parties (current shareholders and lenders of the Company). Currently, we have no significant source of operating revenues, and will require additional outside funding to develop and sustain our future operations.

In order to repay our debt obligations in full or in part when due, we will be required to raise significant capital from other sources. Alternatively, we will be required to negotiate further extensions of the Series B Preferred Stock maturity date and our notes payable, as we have accomplished in the past. There is no assurance, however, that we will be successful in these efforts.

Included in current liabilities and the working capital deficiency at ~~September~~December 3031, 2011 is a $4648,~~404~~144,000 Series B Preferred Stock obligation. The holders of the Series B Preferred Stock (the “Series B Holders”) have agreed to extend the redemption date of the Series B Preferred Stock from time to time and the current redemption date is ~~October~~March 31, ~~2011~~2012, or such later date as agreed to in writing by at least 80% of the Series B Holders.

During 2006 and 2007, we obtained debt financing from 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 currently is ~~October~~March 31, ~~2011~~2012.

In October 2008, as part of a Note Purchase Agreement between the Company and the Series B Holders, we 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 we 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, and had an outstanding balance of $5759,~~307~~456,000 at ~~September~~December 3031, 2011. The maturity date for the Dividend Notes has been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

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 $16,000,000 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. Through ~~September~~December 3031, 2011, the lenders had purchased notes under the Note Purchase Agreement in the aggregate principal amount of $15,~~057~~707,000 and the proceeds had been used by us to cover our minimum operating cash needs. In addition, a total of $5,500,000 of the proceeds was used to partially redeem the Series B Preferred Stock. The Note Purchase Notes provide for the payment of simple interest at the rate of 15% per annum. The maturity date for the Note Purchase Notes has been extended from time to time and currently is March ~~October~~ 31, ~~2011~~2012.

We are currently in default on the Series B Preferred Stock obligation, the 2006/2007 Notes, the Dividend Notes and the Note Purchase Notes. As of the date of filing this report, we were in discussions with the Series B Holders and lenders to further extend the redemption and maturity dates beyond October 31, 2011. Although we have been successful in extending the redemption and maturity dates in the past, there can be no assurance that we will be successful in our current efforts.

Substantially all assets of the Company, including its intellectual property, have been pledged as collateral for the Company’s debt.

There can be no guarantee or assurance that we will be successful in our ability to generate income from operations, or to raise capital at favorable rates or at all. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Reclassifications

Certain amounts in the condensed consolidated financial statements for the three months and six months ended ~~September~~December 3031, 2010 have been reclassified to conform to the presentation for the three months and six months ended ~~September~~December 3031, 2011.

Note 2: Loss per Common Share

The computation of basic net loss per common share is computed using the weighted average number of common shares outstanding during each period. The computation of diluted net loss per common share is based on the weighted average number of shares outstanding during the period plus common stock equivalents which would arise from the exercise of stock options and warrants outstanding using the treasury stock method and the average market price per share during the period, as well as common shares issuable upon the conversion of debt to common stock. Common stock equivalents were not included in the diluted loss per share calculation because the effect would have been anti-dilutive.

The calculation of the weighted average number of common shares outstanding excludes common shares that have been issued as collateral for certain notes payable to related parties. These collateral shares are restricted and bear a legend prohibiting the holder from selling or transferring the shares at any time. The Company has assigned no value to these shares, and the terms of the notes payable require the holder of the collateral shares to return the shares to the Company when the applicable note and accrued interest are paid in full. At ~~September~~December 3031, 2011, the Company had issued 5,350,000 shares of common stock as collateral.

Note 3: Stock Based Compensation

The Company accounts for stock-based compensation in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, Compensation – Stock Compensation. Under the fair value recognition provisions of this statement, stock-based compensation cost is measured at the grant date based on the value of the award granted using the Black-Scholes option pricing model, and recognized over the period in which the award vests. The stock-based compensation expense for the three months and six months ended ~~September~~December 3031, 2011 and 2010 has been allocated to the various categories of operating costs and expenses in a manner similar to the allocation of payroll expense as follows:

	Three Months Ended September 30,

Substantially all related party notes payable of $8992,~~713~~502,000 at ~~September~~December 3031, 2011 are payable to stockholders of the Company who are considered related parties, including the Series B Holders.

Dividend Notes totaling $5759,~~307~~456,000 ($36,962,000 original principal plus $2022,~~345~~494,000 in accrued interest expense added to note principal) resulted from the redemption of 36,962 shares of Series B Preferred Stock in October 2008. The Dividend Notes provide for the payment of interest at the rate of 15% per annum, compounded quarterly, and a rate of interest of 18% per annum during any period in which an event of default has occurred and is continuing. The maturity date for the Dividend Notes has also been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

Pursuant to the Note Purchase Agreement discussed in Note 7, the Company borrowed a total of $15,~~057~~707,000 from the Series B Holders during the period October 1, 2008 to ~~September~~December 3031, 2011, of which $5.5 million was used to redeem 5,500 shares of the Series B Preferred Stock with a book value of $5,500,000. The Note Purchase Notes provide for the payment of simple interest at the rate of 15% per annum. The maturity date for the Note Purchase Notes has been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

During 2006 and 2007, the Company also borrowed a total of $4,400,000 through the issuance of other promissory notes payable to the Series B Holders that 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 currently is ~~October~~March 31, ~~2011~~2012.

Note 6: Dealer Deposits

Dealer deposits consist of amounts received from the Company’s authorized dealers on aircraft in anticipation of full-scale production of the Company’s Hawk 4 gyroplane. The deposit guarantees a delivery sequence number and represents a percentage of the total estimated purchase price. The Company has also issued common stock to dealers as partial consideration for the delay in the certification of the Hawk 4 gyroplane. These costs have been charged to interest expense as incurred. The dealers have been given the opportunity to convert a portion of their deposits into shares of the Company’s restricted common stock. Those dealers that have converted deposits into shares and are now stockholders of the Company are considered related parties. The Company’s intention is to obtain the funding to complete the certification of the ArrowHawk, as a replacement of the Hawk 4, and to convert the Hawk 4 dealer deposits to ArrowHawk dealer deposits. ~~Once~~If and when such funding is obtained, the Company estimates the certification process of the ArrowHawk will require at least three years to complete. Because of the long-term prospects of obtaining the funding and completing the certification, dealer deposits have been recorded as long-term liabilities.

Note 7: Preferred Stock

The Company has authorized 200,000,000 shares of preferred stock having no par value. There are two series of preferred stock with 50,000,000 shares authorized within each series. The rights, terms and preferences of preferred stock are set by the Board of Directors. As of ~~September~~December 3031, 2011, the Board of Directors has set rights, terms and preferences of Series A and Series B Preferred Stock for issue.

Series A Convertible Preferred Stock

As of ~~September~~December 3031, 2011, 1,400,000 shares of Series A Convertible Preferred Stock were issued and outstanding, and held by the following: David Groen, President, Chief Executive Officer and Chairman of the Board of Directors, 1,025,000 shares; Robin Wilson, Executive Vice President, Chief Operating Officer and member of the Board of Directors 125,000 shares; the widow of the late Jay Groen 125,000 shares; and Dennis Gauger, former member of the Board of Directors, 125,000 shares.

The rights, terms and preferences of the Series A Convertible Preferred Stock, as amended, are summarized as follows:

Conversion is allowed at the rate of 25% of the preferred shares for each $30 million in defined cumulative gross sales, for a total of $120 million in sales. This convertibility is also only available if these significant revenue milestones are met within seven years from the date of issue of the Series A Convertible Preferred Stock. · The shares, including all voting and conversion rights, to the extent not converted into common shares, will expire on the later of (i) seven years from the date they are issued and (ii) January 31, 2013, and will be cancelled by the Company. · Upon the death or permanent incapacity of a holder of Series A Convertible Preferred Stock, all shares held by such holder will be divided equally between the then existing members of the Company’s Board of Directors and the holder’s survivor(s) (if more than one person, treated collectively as one person).

On October 9, 2008, as part of a Note Purchase Agreement between the Company and the Series B Holders, the Company redeemed 36,962 shares of the Series B Preferred Stock with a book value of $36,962,000, representing the cumulative total of dividends paid in kind through October 9, 2008. Short-term, interest bearing promissory notes totaling $36,962,000 were issued to the Series B Holders in the redemption.

The Note Purchase Agreement also provides for the periodic sale by the Company to the lenders of short-term promissory notes to provide the Company with operating capital, as specified in the draw requests for such notes. The draw requests must be approved by the lenders. Through ~~September~~December 3031, 2011, the lenders had purchased notes under the Note Purchase Agreement in the aggregate principal amount of $15,~~057~~707,000 and the proceeds had been used by the Company to cover its minimum cash needs. The lenders and the Company have amended the October 9, 2008 Note Purchase Agreement from time to time to increase the aggregate amount of promissory notes that can be purchased to $16,000,000, to provide funding to meet the Company’s monthly minimum financial needs. The lenders are not obligated to purchase notes pursuant to the Note Purchase Agreement and there can be no assurance that the lenders will continue to purchase notes or otherwise provide funding to the Company.

14The redemption date of the Series B Preferred Stock has been extended from time to time and currently is March 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 Stock.

The redemption date of the Series B Preferred Stock has been extended from time to time and currently is October 31, 2011, or such later date as agreed to in writing by the holders of at least 80% of the outstanding shares of Series B Preferred Stock. We are currently in default on this Series B Preferred Stock obligation, and as of the date of filing this report, we were in discussions with the Series B Holders to further extend the redemption date. There can be no assurance that we will be successful in these efforts.

In connection with the execution of the Note Purchase Agreement and the issuance of the Series B Preferred Stock, substantially all assets of the Company, including its intellectual property, have been pledged as collateral for the Company’s debt.

The Company has determined that the extension of the redemption date of the original issuance of the Company’s Series B Preferred Stock in October 2003 met the criteria of a troubled debt restructuring outlined in ASC Topic 470-60, Troubled Debt Restructurings by Debtors. No gain or loss was recorded on the October 2003 extension and subsequent extension of the due date in October 2005. The value of the warrants issued to the Series B Holders in connection with the extensions of the due dates, estimated by the Black-Scholes option pricing model, was charged to interest expense. The Series B Preferred Stock will be classified through its redemption as a troubled debt restructuring.

In accordance with ASC Topic 480, Distinguishing Liabilities from Equity, the Company reports its Series B Preferred Stock as a liability. This pronouncement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances).

Note 8: Common Stock

During the ~~three~~six months ended ~~September~~December 3031, 2011, the Company did not issue any shares of its common stock or any options and warrants to purchase shares of common stock. During the ~~three~~six months ended ~~September~~December 3031, 2011, the recorded amount of common stock has been increased by $12,000 for the periodic adjustment to the value of 3,200,000 variable stock options issued during the year ended June 30, 2006 computed using the Black-Scholes option pricing model. In addition, common stock was decreased by $1,000 to adjust finders’ compensation on the sale of common stock and was increased by $54,000 for total stock-based compensation (see Note 3).

During the ~~three~~six months ended ~~September~~December 3031, 2010, the Company did not issue any shares of its common stock or any options and warrants to purchase shares of common stock. During the ~~three~~six months ended ~~September~~December 3031, 2010, the ~~Company~~recorded ~~charged~~amount of common stock has been increased by $24,000 for a charge to general and administrative expense for the vesting of the grant date fair value of 500,000 options issued to a non-employee consultant and by $60,000 for total stock-based compensation (see Note 3).

The Company has issued shares of its common stock as collateral for certain notes payable to related parties. These collateral shares are restricted and bear a legend prohibiting the holder from selling or transferring the shares at any time. The legend will only be removed if the Company is in default on the applicable loan, at which time, a new certificate will be issued and a value recorded for the shares to account for the loan and accrued interest settled. In addition, the terms of the notes payable require the holder of the collateral shares to return the shares to the Company when the applicable loan and accrued interest are paid in full. The Company has assigned no value to the collateral shares and does not include these shares in the calculation of loss per share. At ~~September~~December 3031, 2011, the Company had issued 5,350,000 shares of common stock as collateral.

Certain shareholder related party note holders may choose to convert outstanding principal and interest balances to common stock of the Company. The conversion prices per share range from $0.10 per share to $1.25 per share. At ~~September 30~~December, 2011, $22,~~436~~925,000 of principal and interest is convertible into 8789,~~079~~154,~~703~~381 shares of the Company’s common stock. The cash price per common share and the conversion prices per share approximated the quoted market price per share of the Company’s common stock on or near the date the note agreements were negotiated. The conversion prices per share have all been set at the market price of the common stock, or above the market price whenever possible, with market price typically established at the price per share that the Company was selling restricted common shares for cash at the time. Because the conversion price per share was generally “under water” in substantially all of these transactions, the Company concluded that the conversion terms did not represent a beneficial conversion feature. Therefore, no beneficial conversion features have been accounted for in the Company’s consolidated financial statements for these transactions.

Note 9: Joint Venture

As previously reported, in December 2010, Groen Brothers Aviation International, LLC (“Groen LLC”), a wholly owned subsidiary of the Company, and Guangzhou Suntrans Aviation Science and Technology Co., Ltd., a company incorporated under the laws of the People’s Republic of China (“Suntrans”), entered into a Cooperative Joint Venture Contract (the “Agreement”) dated as of November 14, 2010 that provided for the establishment of Foshan Suntrans-Groen Aviation Co., Ltd. (the “Joint Venture”) to produce fully-assembled Light Gyroplanes based upon the Company’s SparrowHawk design. The Agreement generally provides that it will only come into force upon approval by the Chinese Examination and Approval Authority (“CEAA”) in accordance with applicable law and that if such approval is not granted, the Joint Venture Agreement shall be null and void. Further, if approval has not been obtained and a business license for the Joint Venture has not been issued within 180 days of the date of signature of the Agreement, the parties shall jointly consult to determine whether to continue with the formation of the Joint Venture and, if after a period of 30 days the parties cannot agree upon a common action to be taken, either party shall have the option to deem the Agreement void and of no effect by giving written notice to the other party. If the Joint Venture should become effective, the Company, through Groen LLC, expects to receive 25% of the equity in the JV in return for its contribution to the JV of its SparrowHawk III assets, rights to SparrowHawk designs and defined SparrowHawk derivatives, and a rotor blade design from the Hawk 4 Gyroplane.

As of the date hereof, the business license for the Joint Venture has not been issued and both the 180 day period and the 30 day period have run. As a result, both parties are free to initiate steps that could lead to the abrogation of the agreement. Although as the date hereof neither party has chosen to take any such step, we can give no assurance that the parties will obtain approval from the CEAA to establish the Joint Venture or that the implementation of the Agreement will ever take place.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward Looking Statements

This management’s discussion and analysis of financial condition and results of operations and other portions of this Quarterly Report on Form 10-Q contain forward-looking information that involves risks and uncertainties. Our actual results could differ materially from those anticipated by this forward-looking information. Factors that could cause or contribute to such differences include, but are not limited to, those discussed or referred to in the Annual Report on Form 10-K for the year ended June 30, 2011, filed on October 13, 2011, under the heading “Forward Looking Statements” and elsewhere. Investors should review this quarterly report on Form 10-Q in combination with our Annual Report on Form 10-K in order to have a more complete understanding of the principal risks associated with an investment in our common stock. This management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included elsewhere in this document.

Background

The Company is engaged in the business of designing and developing new technology for gyroplane and gyrodyne rotor-wing aircraft for military and commercial uses. Following the delays in our Heliplane program for DARPA, lower than anticipated results from sales of SparrowHawk kits, and negative conditions in capital markets, we undertook cost-cutting measures that we hope will allow us to continue to develop our technology on a reduced scale. We have ceased production of the SparrowHawk and effected a substantial reduction in force and have reduced other operating expenditures as well. We currently have no significant operating revenues.

We have completed work on those milestones of Phase I of the DARPA contract where we served as prime contractor and on Phase IB of the DARPA contract where we subsequently served as a subcontractor for rotor systems work to Georgia Institute of Technology (GT), with final payment received by us in September 2009. As of the date of this report, DARPA has not yet announced funding for Phase II and the future involvement of the Company in the DARPA contract is not anticipated.

Significant Series B Preferred Stock and Debt Obligations

From 2006 through the present, we have obtained debt and equity financing primarily from certain lenders who are also stockholders of the Company. As of ~~September~~December 3031, 2011, our obligations to such lenders included: 36% promissory notes issued during 2006 and 2007 in the aggregate principal amount of $4,400,000 (the “2006/2007 Notes”); a $4648,~~404~~144,000 Series B 15% Cumulative Preferred Stock Obligation; 15% secured promissory notes in the aggregate principal amount of $5759,~~307~~456,000 that were issued in satisfaction of accrued dividends of $36,962,000 on the Series B Preferred Stock through October 9, 2008 plus $2022,~~345~~494,000 in interest accrued and added to debt principal through ~~September~~ 30December 31, 2011 (the “Dividend Notes”); and secured 15% promissory notes in the aggregate principal amount of $15,~~057~~707,000 issued pursuant to the Note Purchase Agreement dated October 9, 2008 (the “Note Purchase Notes”). As discussed in more detail below, the redemption date of the Series B Preferred Stock and the maturity dates of the 2006/2007 Notes, the Dividend Notes and the Note Purchase Notes have been extended to ~~October~~March 31, ~~2011~~2012. We ~~are~~ currently in default on the Series B Preferred Stock obligation, the 2006/2007 Notes, the Dividend Notes and the Note Purchase Notes. Accrued interest payable on this debt in default was $9,632,000 at September 30, 2011. As of the date of filing this report, we were in discussions with the Series B Holders and lenders to further extend the redemption and maturity dates beyond October 31, 2011. We currently have no operating revenues to pay the interest accruing on the debt described above and we are currently unable to pay these obligations. Substantially all our assets have been pledged to secure our debts and if the lenders should fail to further extend the redemption dates and maturity dates for such debts as they have done in the past, such lenders could foreclose on substantially all our assets and we would be forced to discontinue our operations. No assurances can be given that the lenders will further extend the redemption and maturity dates for such preferred stock and debt obligations or that if extended, we will be able to generate revenue or other sources of funds in the significant amount required in order to service and ultimately repay such debt.

Going Concern Uncertainty

At ~~September~~December 3031, 2011, we had total current liabilities of $~~163~~169,~~234~~396,000 and current assets of $~~244~~66,000, resulting in a working capital deficiency of $~~162~~169,~~990~~330,000. At ~~September~~December 3031, 2011, we had a total stockholders’ deficit of $~~171~~178,~~633~~073,000.

The Joint Venture Agreement provides that it will only come into force upon approval by the Chinese Examination and Approval Authority (“CEAA”) in accordance with applicable law and if such approval is not granted, the Agreement shall be null and void. Further, Ifif such approval has not been obtained and a Business License for the Joint Venture issued within 180 days of the date of signature of the Agreement, the parties shall jointly consult to determine whether to continue with the formation of the Joint Venture and, if after a period of 30 days the parties cannot agree upon a common action to be taken, then either party shall have the option to deem the Agreement void and of no effect by giving written notice to the other party. The 180 day period from date of signature was reached on May 14, 2011 and the 30 day period on June 13, ~~2001~~2011, and as of the submission of this Report, the Company had not received any confirmation that the Business License had been issued. As a result, both parties are free to initiate steps that could lead to the abrogation of the agreement. Although as of the date hereof, neither party has chosen to take any such step, we can give no assurance that the parties will obtain approval from the CEAA to establish the Joint Venture or that the implementation will ever take place.

InAs ~~October,~~of ~~2010~~the date of this Report, ~~shortly~~the Company is seeking funding to finalize the design and certification of both the ArrowHawk and ShadowHawk for commercial production. For this purpose the Company exhibited a full scale model of the ArrowHawk at the China International Aviation & Aerospace Exhibition in November 2010. Shortly prior to the Exhibition, in October 2010, the Chinese State Council, Central Military Commission, approved the “low-altitude airspace management reform guidance” that ~~indicates~~indicated an impending relaxation of regulations limiting the use of private and other commercial aircraft in China. We believe that as a result, business interest in the development of commercial flight industry in China has been significantly stimulated. In ~~The~~this environment the Company’s exhibit of the ArrowHawk inat China’s inmajor ~~November,~~Airshow ~~2010,~~ attracted substantial notice ~~in this environment~~, including an invitation for Mr. David Groen to be a keynote speaker at the “China International General Aviation Summit” in Shanghai in April 2011. This Conference, held in association with the Civil Aviation Administration of China (“CAAC”), dealt directly with “Opportunities and Challenges under China’s low-Altitude Airspace”.” The Wepositive ~~believe~~response to Mr. Groen’s address to the Conference on the utility of runway-independent gyroplanes tohas encouraged our belief that gyroplanes such as the ArrowHawk, ShadowHawk, and SparrowHawk can take advantage of ~~those~~the ~~opportunities~~new ~~was~~Chinese ~~well received~~regulations.

In this context, several Chinese parties ~~have~~ subsequently approached the Company to explore an interest in cooperation in the development of the Company’s ArrowHawk, ShadowHawk and other advanced gyroplane and gyrodyne products for commercial use. The Company ~~has~~ held meetings with two such parties and, ~~subsequent~~in toeach ~~the~~case ~~end~~in of2011, ~~the~~as ~~third~~previously ~~Quarter~~reported, ~~in each case~~ signed a non-binding Memorandum of Understanding (or equivalent agreement) (hereafter “MOU”) ~~for~~with those parties. Both MOUs envisage the potential development of civil gyroplanes using more advanced technology than ~~the~~that ~~SparrowHawk.

The Company’s continuation as a going concern is dependent on attaining profitable operations, obtaining additional outside financing and/or restructuring its debt obligations, including its Series B Preferred Stock. During the past three ~~two~~ fiscal years, we have funded losses from operations primarily from the issuance of debt to related parties (current shareholders and lenders of the Company). Currently, we have no significant source of operating revenues, and will require additional outside funding to develop and sustain our future operations.

In October 2008, as part of a Note Purchase Agreement between the Company and the Series B Holders, we 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 we 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, and had an outstanding balance of $5759,~~304~~456,000 at ~~September~~December 3031, 2011. The maturity date for the Dividend Notes has been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

Substantially all assets of the Company, including its intellectual property, have been pledged as collateral for the Company’s debt.

Results of Operations

Revenues

As discussed above, we have significantly scaled back the level of our operations, including ceasing production of the SparrowHawk, eliminating substantially all flight training and reducing the level of our involvement in the DARPA contract. We currently have no significant operating revenues. As a result, total miscellaneous operating revenues were $13,000 and $0 in the three months ended ~~September~~December 3031, 2011 and 2010, ~~comprised~~and of$4,000 ~~miscellaneous~~and ~~operating~~$1,000 ~~revenue~~in the six months ended December 31, 2011 and 2010, respectively.

Costs and Expenses

Total cost of sales related to the miscellaneous operating ~~revenue~~revenues was $12,000 and $23,000 in the three months ended ~~September~~December 3031, 2011 and 2010, and $3,000 and $5,000 in the six months ended December 31, 2011 and 2010, respectively.

22General and administrative expenses for the three months ended December 31, 2011 decreased to $494,000 from $680,000 for the three months ended December 31, 2010. General and administrative expenses for the six months ended December 31, 2011 decreased to $1,030,000 from $1,288,000 for the six months ended December 31, 2010. The decrease in our general and administrative expenses in the first three months and six months of the current fiscal year resulted primarily from increased emphasis on research and development activities and the decrease in legal and professional fees.

General and administrative expenses for the three months ended September 30, 2011 decreased to $536,000 from $608,000 for the three months ended September 30, 2010. The decrease in our general and administrative expenses in the first three months of the current fiscal year resulted primarily from decreased legal and accounting expenses and decreased marketing expenses in preparation for trade show opportunities in China.

Other Income and Expenses

As a result of the reduction in our related party notes receivable, related party interest income is currently insignificant to our consolidated financial statements. Related party interest income was $0 for each of the three-month periods ended December 31, 2011 and 2010, and $1,000 for each of the ~~three~~six-month periods ended ~~September~~December 3031, 2011 and 2010.

We realized a gain on extinguishment of debt of $7038,000 and $1256,000 in the three months ended ~~September~~December 3031, 2011 and 2010, and $108,000 and $68,000 in the six months ended December 31, 2011 and 2010, respectively.

Interest expense for the three months ended ~~September~~December 3031, 2011 increased to $3,~~527~~711,000 from $3,~~115~~219,000 for the three months ended ~~September~~December 3031, 2010. Interest expense for the six months ended December 31, 2011 increased to $7,238,000 from $6,334,000 for the six months ended December 31, 2010. We continue to fund our operations with an increase in related party debt, which has resulted in increased interest expense.

Series B Preferred Stock interest expense for the three months ended September 30, 2011 increased to $1,744,000 from $1,510,000 for the three months ended September 30, 2010. Dividends on the Series B Preferred Stock, which are recorded as interest expense, have been “paid in kind” with additional shares of Series B Preferred Stock. This results in increasing levels of Series B Preferred Stock interest expense.22

Series B Preferred Stock interest expense for the three months ended December 31, 2011 increased to $1,740,000 from $1,567,000 for the three months ended December 31, 2010. Series B Preferred Stock interest expense for the six months ended December 31, 2011 increased to $3,484,000 from $3,077,000 for the six months ended December 31, 2010. Dividends on the Series B Preferred Stock, which are recorded as interest expense, have been “paid in kind” with additional shares of Series B Preferred Stock. This results in increasing levels of Series B Preferred Stock interest expense.

Net Loss

The net loss for the three months ended ~~September~~December 3031, 2011 was $6,~~132~~467,000 compared to $5,~~757~~774,000 for the three months ended ~~September~~December 3031, 2010. The net loss for the six months ended December 31, 2011 was $12,599,000 compared to $11,531,000 for the six months ended December 31, 2010. The increase in the net loss in the first three months and six months of the current fiscal year resulted primarily from the increase in interest expense, as further discussed above.

Liquidity and Capital Resources

Series B Preferred Stock Obligation

At ~~September~~December 3031, 2011, we had total current liabilities of $~~163~~169,~~234~~396,000 and current assets of $~~244~~66,000, resulting in a working capital deficiency of $~~162~~169,~~990~~330,000. Included in current liabilities and the working capital deficiency at ~~September~~December 3031, 2011 is a $4648,~~404~~144,000 Series B Preferred Stock obligation ~~which is currently in default~~. With the approval of the Series B Holders, the maturity date of the Series B Preferred Stock has been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012, or such later date as agreed to in writing by at least 80% of the Series B Holders.

During 2006 and 2007, we obtained debt financing from the Series B Holders in exchange for 2006/2007 Notes in the aggregate principal amount of $4,400,000. The 2006/2007 Notes provide for the payment of simple interest at the rate of 36% per annum. The maturity date of the 2006/2007 Notes has been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

23In October 2008, as part of a Note Purchase Agreement between the Company and the Series B Holders, we redeemed $36,962,000 of the outstanding Series B Stock in exchange for short-term interest bearing Dividend Notes. The Dividend Notes provide for the payment of interest at the rate of 15% per annum, compounded quarterly, and had a balance of $59,456,000 at December 31, 2011. The maturity date of the Dividend Notes has also been extended from time to time and currently is March 31, 2012.

The Note Purchase Notes provide for the payment of simple interest at ~~September~~the ~~30,~~rate ~~2011~~of 15% per annum. The maturity date of the ~~Dividend~~Note Purchase Notes has ~~also~~ been extended from time to time and currently is ~~October~~March 31, ~~2011~~2012.

In addition, the Note Purchase Agreement, as amended, provides for the periodic sale by the Company to the lenders of short-term Note Purchase Notes to provide us with operating capital, as specified in the draw requests for such notes. The draw requests must be approved by the lenders. Through September 30, 2011, the lenders had purchased notes under the Note Purchase Agreement in the aggregate principal amount of $15,057,000 and the proceeds had been used by us to cover our minimum operating cash needs. In addition, $5,500,000 of the proceeds was used to redeem 5,500 shares of the Series B Preferred Stock with a book value of $5,500,000. The Note Purchase Notes provide for the payment of simple interest at the rate of 15% per annum. The maturity date of the Note Purchase Notes has been extended from time to time and currently is October 31, 2011.

The lenders and the Company have amended the October 9, 2008 Note Purchase Agreement from time to time to increase the aggregate amount of promissory notes than can be purchased to $16,000,000 to provide funding to meet our monthly minimum financial needs. The lenders are not obligated to purchase notes pursuant to the Note Purchase Agreement and there can be no assurance that the lenders will continue to purchase notes or otherwise provide funding to us.

We are currently in default on the 2006/2007 Notes, the Dividend Notes and the Note Purchase Notes. As of the date of filing this report, we were in discussions with the lenders to further extend the dates beyond October 31, 2011. Accrued interest payable on this debt in default was $9,632,000 at September 30, 2011. Although we have been successful in extending the maturity dates in the past, there can be no assurance that we will be successful in our current efforts.23

Subsequent to September 30, 2011 through November 21, 2011, the Company has received proceeds from debt financing pursuant to the Note Purchase Agreement of $450,000.

In connection with the execution of the Note Purchase Agreement and the issuance of the Series B Preferred Stock, substantially all our assets, including our intellectual property, have been pledged as collateral for our debt.

In order to repay these obligations in full or in part when due, we will be required to raise significant capital from other sources and to meet certain capital requirements under Utah State law. Alternatively, we will be required to negotiate another extension of the Series B Preferred Stock redemption date and the maturity dates of the 2006/2007 Notes, the Dividend Notes and the Stock Purchase Notes, as we have accomplished in the past. There is no assurance, however, that we will be successful in raising the capital required to repay the Series B Preferred Stock and related notes payable obligations or in obtaining a further extension of the Series B Preferred Stock redemption date and the related notes payable maturity dates beyond ~~October~~January 31, ~~2011~~2012.

Other Debt Obligations

Current liabilities at ~~September~~December 3031, 2011 included $8992,~~713~~502,000 notes payable to related parties, comprised of the following:

Series B Holders:
Dividend Notes	$	5759,~~307~~456,000
Note Purchase Notes		15,~~057~~707,000
2006/2007 Notes		4,400,000
		76,764,000
		79,563,000
Other Related Parties		12,~~949~~939,000
Total Related Party Notes Payable	$	8992,~~713~~502,000

Of the other related parties notes, $2,~~611~~595,000 is in default. In addition, we are delinquent in making payments of accrued interest payable of $2,~~351~~456,000 on this related party debt at ~~September~~December 3031, 2011. Most of these related party notes payable are held by long-time shareholders and lenders of the Company and are payable on demand or are short-term in nature. There is no assurance that these related party lenders will not demand payment of this short-term indebtedness in the near future.

Also included in current liabilities at ~~September~~December 3031, 2011 are notes payable and capital lease obligations to unrelated parties of $1,~~376~~375,000, a significant portion of which is in default. In addition, we are delinquent in making payments of accrued interest payable of $~~907~~866,000 on this debt at ~~September~~December 3031, 2011. We continue to make some payments on this indebtedness and continue discussions with many of these vendors and lenders, and have, in most instances, been granted grace periods and extensions without receipt of formal notices of default or threat of legal action. There is no assurance that these vendors and lenders will continue to forebear from collection or legal action.

Operating, Investing and Financing Activities

Net cash used in operating activities was $~~998~~1,851,000 for the ~~three~~six months ended ~~September~~December 3031, 2011, compared to net cash used in operating activities of $12,~~192~~187,000 for the ~~three~~six months ended ~~September~~December 3031, 2010. The decrease in the net cash used in operating activities in the first ~~three~~six months of the current fiscal year is due primarily to the increase in non-cash interest expense and accrued expenses, partially offset by an increase in our net loss for this period.

Net cash used in investing activities for the ~~three~~six months ended ~~September~~December 3031, 2011 and 2010 was $3,000, consisting of the purchase of property and equipment.

We have recently funded losses from operations and net cash used in investing activities primarily from the issuance of debt to related parties (current shareholders and lenders of the Company) and the increase in accrued expenses, and we will require additional funding from these sources to sustain our future operations.

Net cash provided by financing activities was $~~946~~1,653,000 for the ~~three~~six months ended ~~September~~December 3031, 2011, comprised of proceeds from the issuance of debt of $23,~~950~~600,000 and an increase in bank overdraft of $58,000, partially offset by repayment of debt and capital lease obligations of $45,000 and redemption of Series B Preferred Stock of $2,000,000. Net cash provided by financing activities was $~~768~~1,763,000 for the ~~three~~six months ended ~~September~~December 3031, 2010, comprised of proceeds from the issuance of debt of $~~770~~1,760,000 and the increase in bank overdraft of $919,000, partially offset by repayment of debt and capital lease obligations of $1116,000.

25We currently do not have sufficient cash to sustain our operations for the next twelve months. We are dependent on the lenders under the Note Purchase Agreement to continue to fund operating losses in the short-term, or until revenues grow to the point where they are sufficient to cover operating costs and expenses. As discussed above, the Note Purchase Agreement provides for the periodic sale by the Company to the lenders of short-term promissory notes to provide us with operating capital, as specified in the draw requests for such notes. The draw requests must be approved by the lenders. Through the date of filing this report, the lenders had purchased notes under the Note Purchase Agreement in the aggregate principal amount of $15,807,000 and the proceeds had been used by us to cover our minimum operating cash needs. In addition, $5,500,000 of the proceeds was used partially redeem our Series B Preferred Stock. There is no assurance that this funding under the Note Purchase Agreement will continue beyond the current short-term agreement. Further, there is no assurance that we will be successful in either raising sufficient capital from other sources or improving operations.

In addition, $5,500,000 of the proceeds was used partially redeem our Series B Preferred Stock. We are currently in default on our Series B Preferred Stock obligation and other related party debt, and there is no assurance that this funding under the Note Purchase Agreement will continue beyond the current short-term agreement. Further, there is no assurance that we will be successful in either raising sufficient capital from other sources or improving operations.

Management does not anticipate that revenues or expenses will be materially affected by inflation during the next twelve months of operations.

Our operations are not subject to material seasonal fluctuations.

Off Balance Sheet Commitments

We currently have no material non-cancelable operating lease commitments in excess of one year:

Critical Accounting Policies

Our critical accounting policies include the following:

Revenue Recognition – We recognize revenues from goods and services when there is a binding agreement, the product has been completely shipped or service has been delivered, collection is reasonably assured, and we have no significant obligations remaining. Portions of the purchase price of our products collected from customers in advance of product delivery are recorded as deferred revenue. Therefore, revenues from the sale of SparrowHawk gyroplane kits are not recorded until all kit components and parts are delivered to the customer and collection of any remaining amounts due is reasonably assured.

We recognize revenue on government contracts where we serve as the lead contractor as each defined milestone is completed and the requisite meetings are held and technical data submitted and accepted by the contracting party. At that time, we submit an invoice for payment for the respective milestone at the amount specified in the contract. Contract-related expenses incurred by us for each milestone of the contract, including our own labor, travel, supplies and other costs, and the costs of subcontractors and consultants, are deferred as work-in-process inventory and expensed to cost of sales as the contract revenue for the milestone is recognized. When a loss on a contract is projected, however, all contract-related costs and expenses are expensed as incurred.

We recognize revenue on commercial and sub-contractor contracts as each scheduled phase of the contract is completed and invoices are submitted. Contract-related expenses incurred by us for each phase of the contract, including our own labor, travel, supplies and other costs, and the costs of subcontractors and consultants, are deferred as work-in-process inventory and expensed to cost of sales as the contract revenue for the milestone is recognized. When a loss on a contract is projected, however, all contract-related costs and expenses are expensed as incurred.

Impairment of Long-Lived Assets – We periodically review our long-lived assets for impairment when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. We evaluate, at each balance sheet date, whether events and circumstances have occurred which indicate possible impairment. The carrying value of a long-lived asset is considered impaired when the anticipated cumulative undiscounted cash flows of the related asset or group of assets is less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the estimated fair market value of the long-lived asset.

Research and Development Costs – Research and development costs are expensed as incurred in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (“ASC”) Topic 730, Research and Development. The costs of materials and other costs acquired for research and development activities are charged to expense as incurred. Salaries, wages, and other related costs of personnel, as well as other facility operating costs are allocated to research and development expense through management’s estimate of the percentage of time spent by personnel in research and development activities.

Stock-Based Compensation – We have adopted the fair value recognition provisions of ASC Topic 718, Compensation – Stock Compensation, which requires the Company to measure the compensation cost of stock options and other stock-based awards to employees and directors at fair value at the grant date and recognize compensation expense over the requisite service period for awards expected to vest. The grant-date fair value of stock options and other stock-based awards is estimated using the Black-Scholes option-pricing model. The stock-based compensation expense has been allocated to the various categories of costs and expenses in a manner similar to the allocation of payroll expense.

Non-Employee Stock Options and Warrants – In accordance with ASC Topic 505-50, Equity-Based Payments to Non-Employees, we estimate the fair value of the consideration recorded for stock options and warrants issued to non-employees using the Black-Scholes option-pricing model. For those stock options and warrants that have variable characteristics, we will continue to use this methodology to periodically reassess the fair value of the consideration to determine if the value of the consideration recorded in the consolidated financial statements requires adjustment. Changes in the assumptions used in the option-pricing model, including the market price of the Company’s common stock and risk-free interest rates, may result in fluctuations in the estimated fair value and carrying value of the consideration recorded for variable non-employee stock options and warrants.

Financial Instruments with Characteristics of Both Liabilities and Equity – In accordance with ASC Topic 480, Distinguishing Liabilities from Equity, we report our Series B Preferred Stock as a liability. This pronouncement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances).

Income Taxes – We account for income taxes according to the asset and liability method. The asset and liability method requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between tax bases and financial reporting bases of existing assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable. The Company is a smaller reporting company.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, under the supervision and with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of ~~September~~December 3031, 2011, the end of the period covered by this report. Based on that evaluation, our chief executive officer and chief financial officer concluded that ~~as a result of our failure to timely file a current report on Form 8-K,~~ the disclosure controls and procedures employed at the Company as of ~~September~~December 3031, 2011 were ~~not~~ effective such that the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure.

Subsequent to September 30, 2011, we established additional procedures to strengthen our disclosure controls and procedures, including the implementation of additional procedures to identify the actions that require disclosure on Form 8-K and the notification of our outside consultants before the actions are taken. We believe these enhanced procedures will be adequate to cure the deficiencies in our disclosure controls and procedures that existed as of September 30, 2011. However, it should be noted that a controls system cannot provide absolute assurance that the objectives of the controls systems are met and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Change in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during the ~~first~~second quarter of our fiscal year 2012, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not involved in any material pending legal proceedings other than ordinary routine litigation incidental to our business and, to the best of our knowledge, no material legal proceedings against the Company have been threatened. We are subject to the potential of various claims and legal actions arising in the ordinary course of business, including certain matters relating to past due amounts to creditors. The past due amounts are recorded as liabilities in our consolidated financial statements, and management believes that the amount, if any, that may result from other claims will not have a material adverse effect on our consolidated financial statements.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Item 1A – “Risk Factors” in our Annual Report on Form 10-K for the year ended June 30, 2011, which could materially affect our business, financial condition or future results of operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

There were no sales of unregistered equity securities during the three months ended ~~September~~December 3031, 2011.

Item 3. Defaults Upon Senior Securities

We are also delinquent on accrued interest payable on the debt to Series B Holders of $9,632,000 and $2,351,000 on other related party debt.

As of the date of filing this report, we were in discussions with the Series B Holders and lenders to further extend the redemption and maturity dates beyond October 31, 2011. Although we have been successful in extending the redemption and maturity dates in the past, there can be no assurance that we will be successful in our current efforts.

As of September 30, 2011, we are also delinquent in making payments on notes payable and capital lease obligations totaling $1,392,000 and related accrued interest payable of $907,000.
