Electronics Corporation is a systems oriented military electronics development, design and manufacturing organization based in
Oakland, New Jersey with a focus on compact diesel power generation solutions. Its principal products are electronic and electro-mechanical
systems manufactured for the Armed Forces of the United States, which the Company provides as a prime contractor or subcontractor
for the Department of Defense.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;A. Revenue
Recognition&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Revenues and
estimated earnings under long-term defense contracts (including research and development contracts, except as described below
in this paragraph) are recorded using the percentage-of-completion method of accounting, measured as the percentage of costs incurred
to estimated total costs of each contract. For the Company&amp;#146;s indefinite delivery, indefinite quantity contract to provide
2kW generator sets to the military, the ordering provision of which expired on September 30, 2011, and for orders from other Government
subcontractors for 2kW generator sets, percentage-of-completion calculations are based on individual &amp;#147;Delivery Orders&amp;#148;
which are periodically received for specified quantities. These calculations require management to estimate the cost to complete
open orders. Changes between those estimates and the actual cost of completion of delivery orders impact the revenue recognition
in each reporting period. Estimates are adjusted as necessary on a quarterly basis. For research and development contracts total
costs incurred are compared to total expected costs for each contract. During the fiscal year ended June 30, 2013, the Company
had one development contract and one development sub-contract for which it recognized revenues on a time and material basis.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Revenues and
earnings for orders for replacement parts and other short term business (including orders for replacement parts for snowmaking
equipment) are recorded when deliveries of product are made and title and risk of loss have been transferred to the customer and
collection is probable.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;For those
contracts where revenue has been recognized using the percentage-of-completion method of accounting, provisions for estimated
losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions,
and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions
are determined.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
is subject to concentrations of credit risk primarily from cash and accounts receivable. The Company maintains accounts with financial
institutions which exceed the current federally insured maximum of $250,000. The Company minimizes risks associated with cash
by periodically reviewing the credit quality of its primary financial institutions. The Company&amp;#146;s accounts receivable are
principally with agencies of the United States Department of Defense and other Department of Defense contractors. Various Department
of Defense agencies accounted for 24.5% of the Company&amp;#146;s accounts receivable as of June 30, 2013 and two Department of Defense
sub-contractors accounted for 48.9% and 16.9% of the Company&amp;#146;s accounts receivable respectively. As of June 30, 2012 various
agencies of the Department of Defense accounted for 46.1% of the Company&amp;#146;s outstanding accounts receivable and one Department
of Defense sub-contractor accounted for 25.7% of the Company&amp;#146;s accounts receivable.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
derives more than 80% of its revenues from the sale of 2kw portable electrical generator sets to various branches of the United
States military under a long term contract and to other Department of Defense contractors. The contract to supply generator sets
to the Department of Defense is for an indefinite delivery, indefinite quantity and is subject to the Government&amp;#146;s standard
provision for termination at the convenience of the Government. A final delivery order was placed under this contract in September
2011 with deliveries scheduled to occur through September 2013 (when the contract will fully expire). The Company anticipates
that the Government will continue to require the Company&amp;#146;s 2kW generators, which can be ordered under individual &amp;#147;Purchase
Orders&amp;#148;.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;In June 2013,
the U.S. Army announced that it intends to award a new, three year, sole source, indefinite delivery, indefinite quantity contract
to the Company to produce 2kW generator sets. No assurances can be given that the U.S. Army will take such action (or if taken,
the timing thereof) or that the Company would receive any delivery orders under the contract if awarded (or if delivery orders
are received, the timing thereof). Production traditionally begins six to twelve months after the receipt of an order.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
also continues to work toward having these generators available on the General Services Administration&amp;#146;s GSA.gov website
as well as through other websites and sales channels.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
is primarily dependent on four vendors to supply qualified components for its generator products. During fiscal year 2013 two
of these suppliers accounted for 34.2% and 17.1% of material purchases, respectively. These same suppliers accounted for 27.5%
and 14.9% of material purchases in fiscal year 2012. No other supplier accounted for more than 10% of material purchases in fiscal
years 2013 or 2012.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
derives most of its revenues through contracts with various agencies of the Department of Defense including a long-term contract
to supply portable electric generator sets (see &amp;#147;Product Concentration Risk&amp;#148; above), research and development contracts,
and various short-term contracts and awards to supply spare parts and perform repairs on products previously manufactured and
sold by the Company. The Company also provides portable electric generator sets as a sub-contractor to other prime contractors
to the Department of Defense. In fiscal year 2013 the various agencies of the Department of Defense accounted for approximately
73.2% of Company revenues. In fiscal year 2012 the Department of Defense accounted for 73.1% of revenues. No other customer accounted
for more than 10% of the Company&amp;#146;s revenues in fiscal years 2013 or 2012.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;During the
year ended June 30, 2013, the Company had net income of approximately $100,000 and cash flows from operations were approximately
$306,000. The Company believes that the Company&amp;#146;s current cash and its current line of credit, combined with progress payments
as well as billings at the time of delivery of products will be sufficient to support short-term liquidity requirements, working
capital needs and capital expenditures at their current or expected levels.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company&amp;#146;s
10 year contract to provide 2kW generator sets will expire in full on September 30, 2013. As of the date of this Annual Report
the Company is negotiating a new 3 year, sole source, indefinite delivery/indefinite quantity contract with the U.S. Army to produce
2kW generator sets. No assurances can be given that the Company will be awarded such contract(or if awarded, the timing thereof)
or that the Company would receive any delivery orders under the contract if awarded (or if delivery orders are received, the timing
thereof).&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;As of the
date of this Annual Report the Company is in discussions with TD Bank, NA, to renew its Line of Credit for one year until November
30, 2014. In the event the Line of Credit is not renewed by November 30, 2013, on terms acceptable to the Company, the Company
may have to take actions to address this situation, including but not limited to seeking other financing sources (though no assurances
can be given that such financing can be obtained or, if obtained, the timing thereof) and/or making significant alterations to
on-going operations.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
regularly reviews its trade receivables for probability of collection. An assessment of the probability of collection of delinquent
accounts is made and an allowance is recorded when collection becomes uncertain. There was no allowance for doubtful accounts
as of June 30, 2013 or June 30, 2012.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Cost is determined
by the first-in, first-out (FIFO) method. Inventories are valued at the lower of cost or market. Components of inventory cost
include materials, direct labor and overhead that have not been charged to specific contracts.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The preparation
of financial statements in conformity with accounting principles generally accepted in the United States of America requires management
to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period.
These estimates include, among others, lower of cost or market estimates for inventories, realization of deferred tax assets,
allowance for doubtful accounts, revenue recognition and certain accrued expenses. Actual results could differ from those estimates.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

expenses its research and development costs as incurred. These costs consist primarily of salaries and material costs. For the
fiscal years ended June 30, 2013 and 2012, the Company expensed $79,564 and $50,026 respectively, of research and development
costs. Research and development projects performed under contracts for customers are billed to the customer and are recorded as
contract costs as incurred.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
reviews the recoverability of all long-term assets, including the related useful lives, whenever events or changes in circumstances
indicate that the carrying amount of a long-lived asset might not be recoverable. If required, the Company compares the estimated
undiscounted future net cash flows to the related asset&amp;#146;s carrying value to determine whether there has been an impairment.
If an asset is considered impaired, the asset is written down to fair value, which is based either on discounted cash flows or
appraised values in the period the impairment becomes known. There were no impairments of long-term assets in the year ended June
30, 2013 or in the year ended June 30, 2012.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;K. Income
Taxes&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Under the
asset and liability method of accounting for taxes under ASC Topic 740, &amp;#147;Income Taxes&amp;#148;, deferred tax assets and liabilities
are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing
assets and liabilities and their respective tax bases. The effect on deferred tax assets and liabilities of a change in tax laws
is recognized in the results of operations in the period the new laws are enacted. A valuation allowance is recorded to reduce
the carrying amounts of deferred tax assets unless it is more likely than not, that such assets will be realized.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
accounts for uncertain tax positions in accordance with Generally Accepted Accounting Principles in the U.S. Income tax positions
must meet a more-likely-than-not recognition in order to be recognized in the financial statements. The Company recognizes potential
accrued interest and penalties related to unrecognized tax benefits within operations as income tax expense. As new information
becomes available, the assessment of the recognition threshold and the measurement of the associated tax benefit of uncertain
tax positions may result in financial statement recognition or de-recognition.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;L. Deferred
Costs&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;The Company
is continuing to actively pursue possible methods of monetizing the undeveloped and unused portion of its property, by its sale
and/or development. To that end the Company has deferred $65,095 of costs incurred related to these efforts.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;M. Fair Value
Measurements&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Fair value
is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market participants at the measurement date (i.e. an exit price). The accounting guidance includes a fair value hierarchy that
prioritizes the inputs to valuation techniques used to measure fair value. The three levels of the fair value hierarchy are as
follows:&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Level 1 &amp;#150;
Unadjusted quoted prices for identical assets or liabilities in active markets;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Level 2 &amp;#150;
Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or
indirectly for substantially the full term of the asset or liability; and&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Level 3 &amp;#150;
Unobservable inputs for the asset or liability, which include management&amp;#146;s own assumption about the assumptions market participants
would use in pricing the asset or liability, including assumptions about risk.&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;N. Reclassification
of Prior Year Balances&lt;/font&gt;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="font: 8pt Times New Roman, Times, Serif"&gt;Certain prior
year balances have been reclassified to conform to the current period financial statement presentation. This reclassification
