NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except per share data)

(unaudited)

1. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. Therefore, these financial statements should be read in conjunction with the annual report on Form 10-K for the fiscal year ended April 30, 2013. In our opinion, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included. Operating results for the three months ended July 31, 2013 are not indicative of the results of operations that may be expected for the fiscal year ended April 30, 2014.

Certain reclassifications within the condensed financial statement captions have been made to maintain consistency in presentation between years. Financial amounts are in thousands of dollars except per share amounts.

2. Net Income (Loss) Per Share: The Company follows ASC 260 that requires the reporting of both basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. In accordance with ASC 260, any anti-dilutive effects on net earnings (loss) per share are excluded. Potential common shares as of July 31, 2013 are 66,281,237.

3. Research and Development: We invested in research and development activities. The amount invested in the three months ended July 31, 2013 and 2012 was approximately $557 and $372 respectively.

4. Borrowings: At April 30, 2013, the Company was utilizing two lines of credit totaling $3.5 million. The unused line at July 31, 2013 was $2.0 million. During the current year these funds were primarily used for the purchase of inventory and aircraft modification STC development for the modifications and avionics operations.

We believe the line of credit will be extended when it is due and do not anticipate the full repayment of this note in fiscal 2014. Our $1.0 million line of credit has been extended to August 2014. Our $2.5 million line of credit matures April 2015. The lines of credit are collateralized by the first and second positions on all assets of the Company.

At July 31, 2013, there were several notes collateralized by aircraft security agreements totaling $1,779. These notes were used for the purchase and modifications of these collateralized aircraft and Kings Avionics, Inc.

There are three notes at a bank totaling $1,623 for real estate located in Olathe, Kansas and Tempe, Arizona. The due date for these notes is March 2019 and August 2019.

One note totaling $329 remain for real estate purchased in November 2007 and June 2009 in Dodge City, Kansas.

One note with a balance of $136 is collateralized by the first and second position lien on all assets of the Company. This was used as capital for our daily business operations in 2006. There are several other notes collateralized by automobiles and equipment totaling an additional $122.

BHCMC entered into an obligation with Konami Gaming Inc. effective August 1, 2012 in the amount of $1,733. The purchase of the gaming system was installed at Boot Hill Casino in mid-August and has a current balance of $954.

BHCMC arranged to acquire for ownership by the Kansas Lottery additional gaming machines. The balance of this financed payable is $1,767.

We are not in default of any of our notes as of July 31, 2013.

We believe that our current banks will provide the necessary capital for our business operations. However, we continue to maintain contact with other banks that have an interest in funding our working capital needs to continue our growth in operations in 2013 and beyond.

Management Overview

Management is focused on increasing long-term shareholder value from increased cash generation, earnings growth, and prudently managing capital expenditures. We plan to do this by continuing to drive increased revenue from product and service innovations, strategic acquisitions, and targeted marketing programs.

8

Our revenue is primarily derived from two very different business segments; aerospace products and professional services. These segments operate through various Butler National Corporation subsidiaries and affiliates listed in the Company's fiscal year 2013 annual report on Form 10K.

Aerospace Products derives its revenues by designing, engineering, manufacturing, installing, servicing, and repairing products for classic and current production aircraft. These products include JET autopilot service and repairs, Avcon provisions for special mission equipment installations, Kings Avionics equipment sales and installation, and Butler National electronic controls and safety equipment manufacture and sales. Aerospace customers range in size from owners and operators of small single engine airplanes to owners and operators of large commercial and military aircraft. Aerospace Products are sold to and serviced for customers located in many countries of the world.

Aerospace is the legacy part of the Butler National business. Organized over 50 years ago, this business is based upon design engineering and installation innovations to enhance and support products related to airplanes and ground support equipment. These new products included: in the 1960's, aircraft electronic load sharing and system switching equipment, a number of airplane electronic navigation instruments, radios and transponders; in the 1970's, ground based VOR navigation equipment sold worldwide and GPS equipment as we know it today in civilian use; in the 1980's, special mission modifications to business jets for aerial surveillance and conversion of passenger configurations to cargo; in the 1990's, classic aviation support of aging airplanes with enhanced protection of electrical systems through transient suppression devices (TSD), control electronics for military weapon systems and improved aerodynamic control products (Avcon Fins) allowing stability at higher gross weights for additional special mission applications; in the 2000's, improved accuracy of the airspeed and altimeter systems to allow less vertical separation between flying airplanes (RVSM) and acquisition of the JET autopilot product line to support and replace aged electronic equipment in the classic fleet of Learjet airplanes; and in the 2010's, the acquisition of Kings Avionics to provide additional classic airplane support by retrofit of avionics from the past 40 years to modern state of the art equipment for sale worldwide using FAA supplemental type certification to make the installations (STC) acceptable to foreign governments for installation abroad.

Aerospace continues to be a focus for new product design and development. We expect this segment will continue to grow in the future. To address the three to five year business cycles related to the Aerospace industry, in the 1990's, we began providing Professional Services to markets outside the Aerospace industry.

Professional Services derives its revenue from (a) professional management services in the gaming industry through Butler National Service Corporation ("BNSC") and BHCMC, LLC ("BHCMC"), (b) licensed architectural services to the business community through BCS Design ("BCS"), and (c) monitoring services to owners and operators of intelligence gathering systems through Butler National Services, Inc. ("BNSI").

Professional Services grew from the experiences gained from the BNSI monitoring products and services of the 1980's including SCADA systems and products including digital voice technology for the telephone industry and nuclear plant and civil defense warning systems. BNSI sold these Professional Services and products to utilities and municipalities resulting in relatively stable revenue streams. The defense warning products were sold in the 1980's to a third party leaving only the BNSI service business in Florida (on May 1, 2013 we sold our waste water monitoring business (Butler National Services, Inc.) to Beadle Enterprises, LLC.

In the early 1990's, management determined that more revenue stable business units were needed to sustain the Company. Members of the Board of Directors had contacts with several American Indian tribes and other members of the Board were associated with gaming operators in Las Vegas.  After enactment of the 1988 Indian Gaming Regulatory Act (IGRA) we reached out to various Indian tribes with land in the area to explore the opportunities for operations under IGRA. This resulted in the "Stables" an Indian owned casino on Modoc Indian land opened in September 1998 developed and managed by BNSC. The Stables Management Agreement has been available on the website maintained by the National Indian Gaming Commission ("NIGC"). The Stables Management Agreement was subsequently amended by various amendments dated April 30, 2003 (the "First Amendment"), November 30, 2006 (the "Second Amendment"), October 19, 2009 (the "Third Amendment") and September 22, 2011 (the "Fourth Amendment"). The result of the First Amendment, Second Amendment, Third Amendment and Fourth Amendment is to provide that twenty (20%) of net profits from The Stables are distributed to BNSC, to end per the joint venture agreement the participation of the Miami Indian tribe from the business and to extend the duration of the Stables Management Agreement through September 30, 2018. BCS Design assisted with the design, construction and continued refurbishment of the Stables.

From this experience with IGRA and the success of the Indian gaming industry, we determined that the IGRA model may be applicable for state owned gaming. We spent Butler National Corporation innovation, legal and market development funds to design and encourage the use of an Indian owned gaming model in the State of Kansas. From these efforts, Kansas enacted the Kansas Expanded Lottery Act (KELA) in 2007 allowing four state owned casinos to be developed in Kansas. In 2007, BNSC made application to manage a state owned casino. In 2008, BNSC was awarded a fifteen year term to manage the Boot Hill Casino in Dodge City, Kansas pursuant to a Lottery Gaming Facility Management Contract (the "Boot Hill Casino Management Contract"). The Boot Hill Casino Management Contract was amended on December 29, 2009 (the "First Amendment to the Boot Hill Casino Management Contract") to bring the definition of "Fiscal Year" in line with the fiscal year of BNSC (May 1 to April 30). BHCMC was organized to be the manager of the Boot Hill Casino in Dodge City, Kansas. The casino opened in December 2009.

The Phase II expansion of Boot Hill Casino began in early 2012 and was completed in January 2013. The unfinished gaming floor space built during Phase I construction and tenant improvements was funded by tenant improvement leases, gaming machine leases, and casino earnings, with minimum exposure to Butler National Corporation. The Phase II expansion included the interior finish of 15,000 square feet of casino shell and 216 additional gaming machines. Part of the expansion included a breezeway connecting the Boot Hill Casino and the Dodge City special events center (United Wireless Arena). In late January 2013 the snack bar was reopened with additional seating and space as the "Cowboy Cafe."

Results Overview

The three months ending July 31, 2013 revenue decreased 15% to $11.4 million compared to $13.5 million in the three months ending July 31, 2012. In the three months ending July 31, 2013 the professional services revenue was $8.7 million compared to $9.8 million in the three months ending July 31, 2012, a decrease of 11%. There was a decrease of 27% in the aerospace products revenue for the three months ending July 31, 2013. We anticipate future domestic military spending reductions and continued slow growth of the United States economy.

The three months ending July 31, 2013 net income decreased 266% to a loss of $445 compared to net income of $268 in the three months ending July 31, 2012. Diluted earnings per share remained the same at $0.00 for the three months ending July 31, 2013 and July 31, 2012. We continue focusing on our margin expansion initiatives, including efficiencies in our implementation and operational processes and controlling general and administrative expenses. The three months ending July 31, 2013, operating margin was 1%, a decrease of nine percentage points from our margin of 10% in the three months ending July 31, 2012.

Revenues:

Revenue decreased 15% to $11.4 million in the three months ended July 31, 2013, as compared to $13.5 million in the three months ended July 31, 2012.

 Professional Services derives its revenue from professional management services in the gaming industry through BNSC and BHCMC, licensed architectural services to the business community through BCS Design. Revenue from Professional Services decreased 11% for the three months ended to $8.7 million at July 31, 2013, compared to $9.8 million at July 31, 2012.

 Aerospace Products derives its revenue by designing, engineering, manufacturing, installing, servicing and repairing products for classic and current production aircraft. Aerospace products revenue decreased 27% for the three months to $2.7 million at July 31, 2013 compared to $3.7 million at July 31, 2012. We anticipate future domestic military spending reductions and continued slow growth of the United States economy.

Costs and expenses:

Costs and expenses related to Professional Services and Aerospace Products include the cost of engineering, labor, materials, equipment utilization, control systems, security and occupancy.

Costs and expenses decreased 7% in the three months ended July 31, 2013 to $11.3 million compared to $12.2 million in the three months ended July 31, 2012. Costs and expenses were 99% of total revenue in the three months ended July 31, 2013, as compared to 90% of total revenue in the three months ended July 31, 2012. The decreased costs and expenses as a percent of total revenue in the three months ended July 31, 2013 were primarily driven by a decrease in labor and material expenses

Marketing and advertising expenses as a percent of total revenue was 9% in the three months ended July 31, 2013, as compared to 8% in the three months ended July 31, 2012. These expenses decreased 5% to $1,064 in the three months ended July 31, 2013, from $1,120 in the three months ended July 31, 2012. Marketing and advertising expenses include advertising, sales and marketing labor, gaming development costs, and casino and product promotions. Boot Hill Casino marketing expenses decreased $68, however other gaming development expenses increased by $12. The Boot Hill Casino decrease was primarily attributable to additional focus in the professional services business reflecting a marketing plan to target specific marketing sectors to increase destination casino revenue. The Boot Hill Casino and Resort definition of the market includes the area east from the Rocky Mountains to the Mississippi River and the southern Canadian border to the northern border of Mexico.

Employee benefits expenses as a percent of total revenue was 5% in the three months ended July 31, 2013, compared to 4% in the three months ended July 31, 2012. These expenses increased 18% to $568 in the three months ended July 31, 2013, from $482 in the three months ended July 31, 2012. These expenses include the employers' share of all federal, state and local taxes, paid time off for vacation, holidays and illness, employee health and life insurance programs and employer matching contributions to retirement plans. The increased expenses are related to increases in insurance expenses.

Depreciation and amortization expenses as a percent of total revenue was 8% in the three months ended July 31, 2013, compared to 5% in the three months ended July 31, 2012. These expenses increased 24% to $885 in the three months ended July 31, 2013, from $711 in the three months ended July 31, 2012. These expenses include depreciation related to owned assets being depreciated over various useful lives and amortization of intangible items including the Kansas privilege fee related to the Boot Hill Casino being expensed over the term of the gaming contract with the State of Kansas. Phase II expansion to Boot Hill Casino was formally completed in early January 2013 and we began depreciation on $4.9 million of assets with various useful lives. BHCMC, LLC depreciation and amortization expense for the three months ended July 31, 2013 was $404 compared to $226 at July 31, 2012.

General, administrative and other expenses as a percent of total revenue was 13% in the three months ended July 31, 2013, compared to 13% in the three months ended July 31, 2012. These expenses decreased 19% to $1.5 million in the three months ended July 31, 2013, from $1.8 million in the three months ended July 31, 2012. The decrease reflects our cost reduction plan to align overall expenses with the current level of revenue in the Aerospace business segment.  The plan includes reductions in staffing levels and reductions of top-level management compensation.

11

Other income (expense):

Interest and other expenses were $352 in the three months ended July 31, 2013 compared with interest and other expenses of $337 in the three months ended July 31, 2012.  Interest expense increased 12.9% from the three months ended July 31, 2012 to the three months ended July 31, 2013. Interest of $315 was related to obligations of BHCMC, LLC.  A gain on the sale of assets was recorded for Butler National Services, Inc. in the amount of $36.

Operations by Segment

We have two operating segments, Professional Services and Aerospace Products. The Professional Services segment includes revenue contributions and expenditures associated with monitoring services for SCADA systems owned by others, professional architectural services and casino management services. Aerospace Products derives its revenue by designing, engineering, manufacturing, installing, servicing and repairing products for classic and current production aircraft.

The following table presents a summary of our operating segment information for the three months ended July 31, 2013 and July 31, 2012:

Professional Services

 Revenue from Professional Services decreased 11% to $8.7 million for the three months ended July 31, 2013, compared to $9.8 million for the three months ended July 31, 2012.

In the three months ended July 31, 2013 Boot Hill Casino and Resort received gross receipts for the State of Kansas of $10.8 million compared to $11.2 million for the three months ended July 31, 2012. Mandated fees, taxes and distributions reduced gross receipts by $3.5 million resulting in gaming revenue of $7.3 million for the three months ended July 31, 2013 compared to $7.7 million for the three months ended July 31, 2012 a decrease of 5%.

The remaining management and Professional Services revenue include professional management services in the gaming industry, licensed architectural services, food, beverage, and retail from Boot Hill Casino.  Gaming related revenue including food, beverage, and retail decreased 28% to $1.3 million in the three months ended July 31, 2013 from $1.8 million in the three months ended July 31, 2012. Professional Services revenue including architectural, and engineering decreased 43% to $185 for the current three months ended July 31, 2013.

 Costs decreased 7% in the three months ended July 31, 2013 to $4.8 million compared to $5.1 million in the three months ended July 31, 2012. Costs were 55% of segment total revenue in the three months ended July 31, 2013, as compared to 52% of segment total revenue in the three months ended July 31, 2012.  The decrease in direct costs were a result of reductions of electronic gaming machines.

 Expenses decreased 4% in the three months ended July 31, 2013 to $3.2 million compared to $3.3 million in the three months ended July 31, 2012. Expenses were 36% of segment total revenue in the three months ended July 31, 2013, as compared to 34% of segment total revenue in the three months ended July 31, 2012.

Aerospace Products

 Revenue decreased 27% to $2.7 million in the three months ended July 31, 2013 compared to $3.7 million in the three months ended July 31, 2012. This decrease is attributable to reduced revenue of $1.0 million in the aerospace segment. We anticipate future domestic military spending reductions and continued slow growth of the United States economy. In an effort to offset decreased domestic military spending, we have invested in the development of several STCs. These STCs are state of the art avionics and we are aggressively marketing both domestically and internationally.

 Costs decreased by 14% in the three months ended July 31, 2013 to $2.5 million compared to $2.9 million for the three months ended July 31, 2012.  Costs were 94% of segment total revenue in the three months ended July 31, 2013, as compared to 80% of segment total revenue in the three months ended July, 2012.

 Expenses decreased 1% in the three months ended July 31, 2013 at $810 compared to $820 in the three months ended July 31, 2012.  Expenses were 30% of segment total revenue in the three months ended July 31, 2013, as compared to 22% of segment total revenue in the three months ended July 31, 2012.

Employees

Other than persons employed by our gaming subsidiaries there were 84 full time and 1 part time employee on July 31, 2013 compared to 105 full time and 3 part time employees on July 31, 2012. As of September 6, 2013, staffing is 85 full time and 1 part time employees. Our staffing at Boot Hill Casino & Resort on July 31, 2013 was 220 full time and 50 part time employees. At September 6, 2013 there are 211 full time employees and 50 part time employees. None of the employees are subject to any collective bargaining agreements.

Liquidity and Capital Resources

We believe that our current banks will provide the necessary capital for our business operations. However, we continue to maintain contact with other banks that have an interest in funding our working capital needs to continue our growth in operations in fiscal 2014 and beyond.

On May 1, 2011, BHC Investment Company (BHCI) exercised the option to acquire 100% of the Class A Preferred Interest in BHCMC, LLC. The ownership structure of BHCMC, LLC is now:

Membership Interest	Members of Board of Managers		Equity Ownership			Income (Loss) Sharing
Class A		3		20	%		40	%
Class B		4		80	%		60	%

BHCMC, LLC, rents the casino building under the terms of a 25 year lease from BHC Development L.C. "BHCD". Butler National Corporation, its management, or subsidiaries have no ownership interest in BHCI or BHCD.

12

The terms of the agreement between the Kansas Lottery and BNSC/BHCMC require the completion of an addition to the Boot Hill Casino. The Phase II development of an adjacent hotel and community owned special events center was funded by a third party, is completed, and open to the public. The Phase II expansion of Boot Hill Casino began in early 2012 and was completed in January 2013. Phase II expansion of the unfinished gaming floor space built during Phase I construction and tenant improvements was funded by tenant improvement leases, gaming machine leases, and casino earnings, with minimum exposure to Butler National Corporation. The Phase II expansion included the interior finish of 15,000 square feet of casino shell and 216 additional gaming machines. Part of the expansion included a breezeway connecting the Boot Hill Casino and the Dodge City special events center (United Wireless Arena). In late January 2013 the snack bar was reopened with additional seating and space as the "Cowboy Cafe."

Analysis and Discussion of Cash Flow

During the three months ended July 31, 2013 our cash position decreased by $587.  We had a net loss of $53. Cash flows from operating activities provided $647.  Non-cash activities consisting of depreciation and amortization contributed $1,100 and stock options issued to employees and directors contributed $8.  Customer deposits increased our cash position by $391, in addition to a net tax change of $37 and prepaid expenses of $2.  An increase in accounts receivable of $182, increases in inventory of $306 and increases in accounts payable and accrued expenses of $240 all decrease our cash position.  We had a gain on the sale of select assets in the amount of $36.

Cash used in investing activities was $106.  We invested $17 for property improvements in Dodge City and invested approximated $89 for equipment at Boot Hill Casino and Resort.

Cash used in financing activities was $1,128.  We reduced our debt by $1,215 and increased our line of credit by $87.  The increase borrowings on the line of credit were a result of the development of the Lear 20 series stage 3 noise suppression device.

Critical Accounting Policies and Estimates:

We believe that there are several accounting policies that are critical to understanding our historical and future performance, as these policies affect the reported amount of revenue and other significant areas involving management judgments and estimates. These significant accounting policies relate to revenue recognition, the use of estimates, long-lived assets, and Supplemental Type Certificates. These policies and our procedures related to these policies are described in detail below and under specific areas within this "Management Discussion and Analysis of Financial Condition and Results of Operations." In addition, Note 1  to the consolidated financial statements of our Form 10-K for the fiscal year ended April 30, 2013 expands upon discussion of our accounting policies.

Revenue Recognition: Generally, we perform aircraft modifications under fixed-price contracts. Revenue from fixed-price contracts are recognized on the percentage-of-completion method, measured by the direct labor and material costs incurred compared to total estimated direct labor costs. Each quarter our management reviews the progress and performance of our significant contracts. Based on this analysis, any adjustment to sales, cost of sales and/or profit is recognized as necessary in the period they are earned. Changes in estimates of contract sales, cost of sales and profits are recognized using a cumulative catch-up, which is recognized in the current period of the cumulative effect of the change on current or prior periods. Revenue for off-the-shelf items and aircraft sales is recognized on the date of sale.

Revenue from Avionics products are recognized when shipped. Payment for these Avionics products is due within 30 days of the invoice date after shipment. Revenue for SCADA services, Gaming Management, and other Corporate/Professional Services are recognized as the service is rendered and invoiced. Payments for these service invoices are usually received within 30 days.

In regard to warranties and returns, our products are special order and are not suitable for return. Our products are unique upon installation and tested prior to their release to the customer and acceptance by the customer. In the rare event of a warranty claim, the claim is processed through the normal course of business and may include additional charges to the customer. In our opinion any future warranty work would not be material to the financial statements.

Gaming revenue is the gross gaming win as reported by the Kansas Lottery casino reporting systems, less the mandated payments by and for the State of Kansas. Electronic games-slots and table games revenue is the aggregate of gaming wins and losses. Liabilities are recognized for chips and "ticket-in, ticket-out" coupons in the customers' possession, and for accruals related to anticipated payout of progressive jackpots. Progressive gaming machines, which contain base jackpots that increase at a progressive rate based on the number of coins played, are deducted from revenue as the amount of jackpots increase. Food, beverage, and other revenue is recorded when the service is received and paid for.

13

Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may be material to our financial statements.

Long-lived Assets: The Company accounts for its long-lived assets in accordance with ASC Topic 360-10, formerly SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets." ASC Topic 360-10 requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical cost carrying value of an asset may no longer be appropriate. The Company assesses recoverability of the carrying value of an asset by estimating the future net cash flows expected to result from the asset, including eventual disposition. If the future net cash flows are less than the carrying value of the asset, an impairment loss is recorded equal to the difference between the asset's carrying value and fair value or disposable value.

Supplemental Type Certificates: Supplemental Type Certificates (STCs) are authorizations granted by the Federal Aviation Administration (FAA) for specific modification of a certain aircraft. The STC authorizes us to perform modifications, installations, and assemblies on applicable customer-owned aircraft. Costs incurred to obtain STCs are capitalized and subsequently amortized against revenue being generated from aircraft modifications associated with the STC. The costs are expensed as services are rendered on each aircraft through costs of sales using the units of production method. The legal life of an STC is indefinite. We believe we have enough future sales to fully amortize our STC development costs.

Changing Prices and Inflation

We have experienced upward pressure from inflation in fiscal year 2013. From fiscal year 2012 to fiscal year 2013 a majority of the increases we experienced were in material costs. This additional cost may not be transferable to our customers resulting in lower income in the future. We anticipate fuel costs and possibly interest rates to rise in fiscal 2014 and 2015.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Please see Item 7(a) of our Form 10-K for the period ended April 30, 2013, which such Item is incorporated herein by reference.

Item 4. CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in our filings under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission rules and forms. Our principal executive and financial officers have evaluated our disclosure controls and procedures as of the end of the period covered by this report on Form 10-K and have determined that such disclosure controls and procedures are effective, based on criteria in Internal Control-Integrated Framework, issued by COSO.

Evaluation of disclosure controls and procedures: Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures.

In connection with the preparation of this Form 10-Q, our Chief Executive Officer and our Chief Financial Officer conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of July 31, 2013. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of July 31, 2013.

Internal Control Over Financial Reporting

Changes in Internal Control Over Financial Reporting: In our opinion there were no material changes in the Company internal controls over financial reporting during the quarter covered in this report that have materially affected, or are reasonably likely to materially affect, its internal controls over financial reporting.

14

Limitations on Controls

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Organization, Consolidated and Presentation of Financial Statements [Abstract]

Organization, Consolidated and Presentation of Financial Statements

1. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. Therefore, these financial statements should be read in conjunction with the annual report on Form 10-K for the fiscal year ended April 30, 2013. In our opinion, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included. Operating results for the three months ended July 31, 2013 are not indicative of the results of operations that may be expected for the fiscal year ended April 30, 2014.

Certain reclassifications within the condensed financial statement captions have been made to maintain consistency in presentation between years. Financial amounts are in thousands of dollars except per share amounts.

Borrowings [Abstract]

Borrowings

4. Borrowings: At April 30, 2013, the Company was utilizing two lines of credit totaling $3.5 million. The unused line at July 31, 2013 was $2.0 million. During the current year these funds were primarily used for the purchase of inventory and aircraft modification STC development for the modifications and avionics operations.

We believe the line of credit will be extended when it is due and do not anticipate the full repayment of this note in fiscal 2014. Our $1.0 million line of credit has been extended to August 2014. Our $2.5 million line of credit matures April 2015. The lines of credit are collateralized by the first and second positions on all assets of the Company.

At July 31, 2013, there were several notes collateralized by aircraft security agreements totaling $1,779. These notes were used for the purchase and modifications of these collateralized aircraft and Kings Avionics, Inc.

There are three notes at a bank totaling $1,623 for real estate located in Olathe, Kansas and Tempe, Arizona. The due date for these notes is March 2019 and August 2019.

One note totaling $329 remain for real estate purchased in November 2007 and June 2009 in Dodge City, Kansas.

One note with a balance of $136 is collateralized by the first and second position lien on all assets of the Company. This was used as capital for our daily business operations in 2006. There are several other notes collateralized by automobiles and equipment totaling an additional $122.

BHCMC entered into an obligation with Konami Gaming Inc. effective August 1, 2012 in the amount of $1,733. The purchase of the gaming system was installed at Boot Hill Casino in mid-August and has a current balance of $954.

BHCMC arranged to acquire for ownership by the Kansas Lottery additional gaming machines. The balance of this financed payable is $1,767.

We are not in default of any of our notes as of July 31, 2013.

We believe that our current banks will provide the necessary capital for our business operations. However, we continue to maintain contact with other banks that have an interest in funding our working capital needs to continue our growth in operations in 2013 and beyond.

The exercise price for the incentive stock options is $0.49.

The incentive stock options are allocated in three groups with two conditions for vesting. The first condition is stock price and the second condition is time. There are 2,420,688 options at $0.49 that may be exercised if and when the share price reaches $0.92, and 2,420,688 options at $0.49 that may be exercised if and when the share price reaches $1.41, and 2,420,688 options at $0.49 that may be exercised on or after December 31, 2013 if and when the share price reaches $1.90.

Net Income (Loss) Per Share

2. Net Income (Loss) Per Share: The Company follows ASC 260 that requires the reporting of both basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. In accordance with ASC 260, any anti-dilutive effects on net earnings (loss) per share are excluded. Potential common shares as of July 31, 2013 are 66,281,237.
