Inc. (the “Company”) was founded in 1984 in New Jersey, commenced business operations in 1994 and re-incorporated in
Delaware in 2007. The Company is developing and commercializing its proprietary systems that generate electricity by harnessing
the renewable energy of ocean waves. The Company uses proprietary technologies that convert the mechanical energy created by the
heaving motion of ocean waves into electricity. The Company has designed and continues to develop the PowerBuoy® product line
which is based on modular, ocean-going buoys, which the Company has been periodically ocean testing since 1997. The Company markets
its PowerBuoys® in the United States and internationally. Since fiscal 2002, government agencies have accounted for a significant
portion of the Company’s revenues. These revenues were largely for the support of product development efforts relating to
our technology. Today our goal is to generate the majority our revenue from the sale or lease of products, and sales and services
to support our business operations. As we continue to develop and commercialize our products and services, we expect to have a
net use of cash from operating activities unless and until we achieve positive cash flow from the commercialization of products
and services.</p>

financial statements have been prepared assuming the Company will continue as a going concern. The Company has experienced substantial
and recurring losses from operations, which have contributed to an accumulated deficit of $209.8 million at April 30, 2019. At
April 30, 2019, the Company had approximately $17.2 million in cash, cash equivalents and restricted cash on hand. The Company
generated revenues of only $0.6 million and $0.5 million during the years ended April 30, 2019 and 2018, respectively. Based on
the Company’s cash, cash equivalents and restricted cash balances as of April 30, 2019, the Company believes that it will
be able to finance its capital requirements and operations into the quarter ending July 31, 2020. The Company will require additional
equity and/or debt financing to continue its operations. The Company cannot provide assurances that it will be able to secure additional
funding when needed or at all, or, if secured, that such funding would be on favorable terms. These factors raise substantial doubt
about the Company’s ability to continue as a going concern.</p>

different strategies to obtain the required additional funding for future operations. These strategies may include, but are not

and 2018, the Company has continued to make investments in ongoing product development efforts in anticipation of future growth.
The Company’s future results of operations involve significant risks and uncertainties. Factors that could affect the Company’s
future operating results and cause actual results to vary materially from expectations include, but are not limited to, risks from
lack of available financing and insufficient capital, performance of PowerBuoys®, its inability to market and commercialize
its PowerBuoys®, technology development, scalability of technology and production, dependence on skills of key personnel,
concentration of customers and suppliers, deployment risks and laws, regulations and permitting. In order to continue to implement
its business strategy, the Company requires additional equity and/or debt financing. The Company closed five equity financing arrangements
during the two-year period ended April 30, 2019. The Company does not currently have any committed sources of debt or equity financing,
and the Company cannot assure that additional equity and/or debt financing will be available to the Company as needed on acceptable
terms, or at all. Historically, the Company has raised capital through securities sales in the public capital markets. If sufficient
additional financing is not obtained when needed, the Company may be required to further curtail or limit operations, engineering
and product development costs, and/or selling, general and administrative activities in order to reduce its cash expenditures.
This could cause the Company to be unable to execute its business plan, take advantage of future opportunities and may cause it
to scale back, delay or eliminate some or all of its product development activities and/or reduce the scope of or cease its operations.</p>

as soon as possible. Pursuant to the direction of the Board, the Company filed a Certificate of Amendment to our Certificate of
Incorporation to affect a one-for-twenty reverse stock split of our common stock (the “Reverse Stock Split”). As of
the close of markets on March 11, 2019, the effective date of the Reverse Stock Split, every twenty shares of issued and outstanding
common stock were combined into one issued and outstanding share of common stock, without any change in the par value per share.
Any fractional shares in connection with the Reverse Stock Split were rounded up to the nearest whole share and no cash payments
were made by the Company to stockholders in lieu of fractional shares. The common stock began trading on a reverse stock split-adjusted

consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">The preparation
of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating
to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates
and assumptions include fair value of warrant liabilities; estimated costs to complete projects and percentage of completion of
customer contracts for purposes of revenue recognition. Actual results could differ from those estimates. The current economic
environment, particularly the macroeconomic pressures in certain European countries, has increased the degree of uncertainty inherent
in those estimates and assumptions.</p>

Recognition</i></b></p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">A performance obligation
is the unit of account for revenue recognition. The Company assesses the goods or services promised in a contract with a customer
and identifies as a performance obligation either: a) a good or service (or a bundle of goods or services) that is distinct; or
b) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer.
A contract may contain a single or multiple performance obligations. For contracts with multiple performance obligations, the Company
allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which
represents the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone
selling price based upon the facts and circumstances of each obligated good or service. The majority of the Company’s contracts
have no observable standalone selling price since the associated products and services are customized to customer specifications.
As such, the standalone selling price generally reflects the Company’s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The nature of the
Company’s contracts may give rise to several types of variable consideration, including claims and unpriced change orders;
awards and incentive fees; and liquidated damages and penalties. Variable consideration can also arise from modifications to the
scope of services. Variable consideration is included in the transaction price to the extent it is probable that a significant
reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved.
Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based
largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted)
that is reasonably available to us.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company recognizes
revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1) at a point
in time or (2) over time. A good or service is transferred when or as the customer obtains control of it. The evaluation of whether
control of each performance obligation is transferred at a point in time or over time is made at contract inception. Input measures
such as costs incurred or time elapsed are utilized to assess progress against specific contractual performance obligations for
the Company’s services. The selection of the method to measure progress towards completion requires judgment and is based
on the nature of the services to be provided. For the Company, the input method using costs incurred or time elapsed best represents
the measure of progress against the performance obligations incorporated within the contractual agreements. When the Company’s
estimate of total costs to be incurred to satisfy the performance obligations exceed revenue, the Company recognizes the loss immediately.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">The Company classifies
leases as either operating or capital lease arrangements in accordance with the authoritative accounting guidance contained within
Accounting Standards Codification (“ASC”) Topic 840, <i>“Leases”.</i> At inception of the contract,
the Company evaluates the lease against the four lease classification criteria within ASC Topic 840. In general, if one of the
four criteria is met, then the lease is accounted for as a capital lease. All others are treated as an operating lease. For operating
leases, lessee payments are recorded to revenue on a straight-line basis over the term of the lease.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company’s
contracts are either cost plus or fixed price contracts. Under cost plus contracts, customers are billed for actual expenses incurred
plus an agreed-upon fee. Under cost plus contracts, a profit or loss on a project is recognized depending on whether actual costs
are more or less than the agreed upon amount.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company has two
types of fixed price contracts, firm fixed price and cost-sharing. Under firm fixed price contracts, the Company receives an agreed-upon
amount for providing products and services specified in the contract, a profit or loss is recognized depending on whether actual
costs are more or less than the agreed upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer
is only intended to fund a portion of the costs on a specific project. Under cost sharing contracts, an amount corresponding to
the revenue is recorded in cost of revenues, resulting in gross profit on these contracts of zero. The Company’s share of
the costs is recorded as product development expense. For the twelve-month period ended April 30, 2019 and 2018 all of the Company’s
contracts were classified as firm fixed price.</p>

consists primarily of equipment, furnishings, fixtures, computer equipment and leasehold improvements and are recorded at cost.
Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets. Expenses
for maintenance and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets
to be held and used is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows
expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment
charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.</p>

Instruments with Characteristics of Both Liabilities and Equity” in Topic 480 which provides that warrants meeting the classification
of a liability award are recorded as a liability at its fair value. The warrant liabilities are subject to re-measurement at each
balance sheet date using the Black-Scholes option pricing model. The Company recognizes any change in fair value in its consolidated
statements of operations within “Gain due to the change in fair value of warrant liabilities”. The Company will continue
to adjust the carrying value of the warrants for changes in the estimated fair value until such time as these instruments are exercised
or expire. At that time, the liabilities will be reclassified to “Additional paid-in capital”, a component of “Stockholders’
equity” on the Consolidated Balance Sheets. The warrants issued in connection with the Company’s public offerings in
June and July 2016 met the criteria of a liability award and were classified in warrant liabilities. The pre-funded and common
warrants issued in the Company’s April 8, 2019 public offering did not meet the criteria to be classified as a liability
award and therefore were treated as an equity award.</p>

operating lease. Rent payments relating to the Monroe premises are subject to annual increases. The minimum monthly payments will
vary over the 7-year term of the lease. The Company will record rent expense on a straight-line basis over the 7-year term of the

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">In May 2014, the
Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “<i>Revenue
from Contracts with Customers (Topic 606).”</i> ASU 2014-09 outlines a new, single comprehensive model for entities
to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance,
including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and
how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services
to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services.
The FASB subsequently issued additional clarifying standards to address issues arising from implementation of the new revenue standard,
including a one-year deferral of the effective date for the new revenue standard. Public companies should now apply the guidance
in ASU 2014-09 to annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods. Earlier
application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within
that annual period. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. Under
the full retrospective method, the standard would be applied to each prior reporting period presented and the cumulative effect
of applying the standard would be recognized at the earliest period shown. Under the modified retrospective method, the cumulative
effect of applying the standard would be recognized at the date of application. Effective May 1, 2018, the Company adopted the
requirements of ASU 2014-09 using the modified retrospective method. As a practical expedient, the Company adopted the new standard
only for existing contracts as of May 1, 2018, the date of adoption. Any contracts that had expired prior to May 1, 2018 were not
evaluated against the new standard. The Company adopted ASU 2014-09 and the adoption did not have a material impact on the Company’s
consolidated financial position, results of operations or cash flows.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">In February 2016,
the FASB issued ASU No. 2016-02, <i>“Leases (Topic 842</i>)” which amends the existing guidance on accounting
for leases. Topic 842 was further clarified and amended within ASU 2017-13, ASU 2018-01, ASU 2018-10, ASU 2018-11 and ASU 2018-20.
The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the
balance sheet for all leases with terms longer than twelve months or leases that contain a purchase option that is reasonably certain
to be exercised. Leases will be classified as either finance or operating, with classification affecting the pattern of expense
recognition in the income statement. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim
periods within those annual periods, with early adoption permitted. The company will adopt Topic 842 during the first quarter of
2019 using the modified retrospective method. The new guidance will be applied to leases that exist or are entered into on or after
May 1, 2019 without adjusting comparative periods in the financial statements. The company expects to utilize the package of practical
expedients in ASC 842-10-65-1(f) that, upon adoption of Topic 842, allows entities to (1) not reassess whether any expired or existing
contracts are or contain leases, (2) retain the classification of leases (e.g., operating or finance lease) existing as of the
date of adoption and (3) not reassess initial direct costs for any existing leases. Based on the most recent assessment of existing
leases, the Company expects to record a right-of-use asset and lease liability in the range of $1.0 to $2.0 million that will be
included on the balance sheet as of May 1, 2019. The Company does not expect the adoption of Topic 842 to have a material impact
on the company’s results of operations or cash flows.</p>

is to reduce diversity in practice of classifying certain items. The amendments in the ASU are effective for fiscal years beginning

by the Company’s stockholders, the Company’s 2015 Omnibus Incentive Plan (the “2015 Plan”) became effective.
A total of 12,036 shares were authorized for issuance under the 2015 Omnibus Incentive Plan, including shares available for awards
under the 2006 Stock Incentive Plan remaining at the time that plan terminated, or that were subject to awards under the 2006 Stock
Incentive Plan that thereafter terminated by reason of expiration, forfeiture, cancellation or otherwise. On October 21, 2016,
upon approval by the Company’s stockholders, the Company increased the number of shares authorized for issuance to 32,036.
If any award under the 2006 Stock Incentive Plan or 2015 Plan expires, is cancelled, terminates unexercised or is forfeited, those
shares become again available for grant under the 2015 Plan. As of April 30, 2019, the Company has 58,555 shares available for
future issuance under the 2015 Plan.</p>

number of shares of stock subject to Awards that can be granted under the 2015 Plan in any one calendar year to any person, other
than a non-employee director, is 3,750. However, incentive stock options may only be granted to employees. The limitation on the
amount of shares of stock issuable under the 2015 Plan is subject to adjustment in the event of certain changes in the Company’s
capital stock, such as recapitalizations, reclassifications, stock splits, reverse stock splits, spin-offs, combinations of our
stock, exchanges of the Company’s stock and other increases or decreases in the Company’s stock without receipt of

and reports certain financial and non-financial assets and liabilities on a fair value basis. Fair value is 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 (exit price). GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value
hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority
to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy
is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels.</p>

and alleges claims for breach of contract, unjust enrichment, conversion, and fraud, negligent and/or reckless misrepresentation

complaint seeks damages in the amount of $2,825,130 together with interest, costs, attorney’s fees, punitive damages and

process. The parties participated in mediation on November 15, 2018 but were unable to reach an agreement. However, the parties

$50,000 within 10 days after the final execution of the Settlement and (ii) another $150,000 on or before May 1, 2019. Subsequently,
the parties filed a stipulation of dismissal of both Tide Runner’s complaint and the Company’s counterclaim with prejudice

for the matters in dispute in the litigation and will indemnify each other for future similar claims. As of April 30, 2019, the

a penalty of $132,000 to Selling, general and administrative costs in the Statement of Operations. The Spanish tax inspector has
recently closed its discussion relating to the capitalization of expenses and as of April 30, 2018 the Company reversed the penalty.
However, during the fiscal year ended April 30, 2018 the Spanish tax inspector raised questions with respect to the Company’s
recognition of funds received in 2011 to 2014 from a governmental grant from the European Commission in connection with the Waveport
project. It is anticipated that we will be assessed a penalty relating to these tax years. The Company has estimated this penalty

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">In assessing the
realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred
tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable
income during the periods in which those temporary differences and carry forwards become deductible or are utilized. As of April
30, 2019 and 2018, based upon the level of historical taxable losses, valuation allowances of $41.7 million and $39.3 million,
respectively, were recorded to fully offset deferred tax assets. The valuation allowance increased $2.5 million during the year
ended April 30, 2019 and decreased $15.4 million during the year ended 2018 respectively.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">As of April
30, 2019, the Company had net operating loss carry forwards for federal income tax purposes of
approximately $152.5 million, which begin to expire in fiscal 2019. The Company also had federal research and
development tax credit carry forwards of approximately $3.2 million as of April 30, 2019, which begins to expire in 2019. The
Tax Reform Act of 1986 contains provisions that limit the utilization of net operating loss and tax credit carry forwards if
there has been an ownership change, as defined. The Company has determined that such an ownership change, as described in
Section 382 of the Internal Revenue Code, occurred in conjunction with the Company’s U.S. initial public offering in
April 2007. The Company’s annual Section 382 limitation is approximately $3.3 million. The Section 382 limitation is
cumulative from year to year, and thus, to the extent net operating loss or other credit carry forwards are not utilized up
to the amount of the available annual limitation, the limitation is carried forward and added to the following year’s
available limitation. Such limitation only applies to net operating losses incurred in periods prior to the ownership change.
The Company has not performed additional analysis on ownership changes that may have occurred subsequently to further limit
the ability to utilize net tax attributes. As of April 30, 2019, the Company had state net operating loss carry forwards of
approximately $23.3 million which begin to expire in 2037, which also may be limited to utilization limitations. As of
April 30, 2019, the Company had foreign net operating loss carry forwards of approximately $16.9 million. The ability
to utilize these carry forwards may also be limited in the event of a significant change to ownership.</p>

the guidance issued by the FASB for the accounting and reporting of uncertain tax positions. The guidance requires the Company
to recognize in its consolidated financial statements the impact of a tax position if that position is more likely than not to
be sustained upon examination, based on the technical merits of the position. The Company is currently undergoing an income tax
audit in Spain for the period from 2008 to 2014, when the Company’s Spanish branch was closed (see Note 15 to the Consolidated
Financial Statements) . At April 30, 2019 and 2018, the Company had no other unrecognized tax positions. The Company does not expect
any material increase or decrease in its income tax expense in the next twelve months, related to examinations or uncertain tax
positions. U.S. federal and state income tax returns were audited through fiscal 2014 and fiscal 2010 respectively. Net operating
loss and credit carry forwards since inception remain open to examination by taxing authorities and will continue to remain open
for a period of time after utilization.</p>

balances and transactions have been eliminated in consolidation. The Company also periodically evaluates its relationships with

such entities. If the determination is made that the Company is the primary beneficiary, then that entity is included in the consolidated
financial statements. As of April 30, 2019, there were no such entities.</p>

of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating
to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates
and assumptions include fair value of warrant liabilities; estimated costs to complete projects and percentage of completion of
customer contracts for purposes of revenue recognition. Actual results could differ from those estimates. The current economic
environment, particularly the macroeconomic pressures in certain European countries, has increased the degree of uncertainty inherent
in those estimates and assumptions.</p>

consists primarily of equipment, furnishings, fixtures, computer equipment and leasehold improvements and are recorded at cost.
Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets. Expenses
for maintenance and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets
to be held and used is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows
expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment
charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">In May 2014, the
Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “<i>Revenue
from Contracts with Customers (Topic 606).”</i> ASU 2014-09 outlines a new, single comprehensive model for entities
to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance,
including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and
how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services
to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services.
The FASB subsequently issued additional clarifying standards to address issues arising from implementation of the new revenue standard,
including a one-year deferral of the effective date for the new revenue standard. Public companies should now apply the guidance
in ASU 2014-09 to annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods. Earlier
application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within
that annual period. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. Under
the full retrospective method, the standard would be applied to each prior reporting period presented and the cumulative effect
of applying the standard would be recognized at the earliest period shown. Under the modified retrospective method, the cumulative
effect of applying the standard would be recognized at the date of application. Effective May 1, 2018, the Company adopted the
requirements of ASU 2014-09 using the modified retrospective method. As a practical expedient, the Company adopted the new standard
only for existing contracts as of May 1, 2018, the date of adoption. Any contracts that had expired prior to May 1, 2018 were not
evaluated against the new standard. The Company adopted ASU 2014-09 and the adoption did not have a material impact on the Company’s
consolidated financial position, results of operations or cash flows.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">In February 2016,
the FASB issued ASU No. 2016-02, <i>“Leases (Topic 842</i>)” which amends the existing guidance on accounting
for leases. Topic 842 was further clarified and amended within ASU 2017-13, ASU 2018-01, ASU 2018-10, ASU 2018-11 and ASU 2018-20.
The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the
balance sheet for all leases with terms longer than twelve months or leases that contain a purchase option that is reasonably certain
to be exercised. Leases will be classified as either finance or operating, with classification affecting the pattern of expense
recognition in the income statement. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim
periods within those annual periods, with early adoption permitted. The company will adopt Topic 842 during the first quarter of
2019 using the modified retrospective method. The new guidance will be applied to leases that exist or are entered into on or after
May 1, 2019 without adjusting comparative periods in the financial statements. The company expects to utilize the package of practical
expedients in ASC 842-10-65-1(f) that, upon adoption of Topic 842, allows entities to (1) not reassess whether any expired or existing
contracts are or contain leases, (2) retain the classification of leases (e.g., operating or finance lease) existing as of the
date of adoption and (3) not reassess initial direct costs for any existing leases. Based on the most recent assessment of existing
leases, the Company expects to record a right-of-use asset and lease liability in the range of $1.0 to $2.0 million that will be
included on the balance sheet as of May 1, 2019. The Company does not expect the adoption of Topic 842 to have a material impact
on the company’s results of operations or cash flows.</p>

the FASB issued ASU 2016-15, <i>“Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash
Payments”,</i> providing additional guidance on eight specific cash flow classification issues. The goal of the ASU
is to reduce diversity in practice of classifying certain items. The amendments in the ASU are effective for fiscal years beginning
after December 15, 2017, and interim periods within those fiscal years and early adoption is permitted. The Company adopted the
standard on May 1, 2018 and determined the standard had no impact on its financial position, results of operation or cash flows.</p>

clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. Entities
should apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The
amendments in the ASU are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal
years and early adoption is permitted. The Company adopted the standard on May 1, 2018 and determined the standard had no impact

FASB issued ASU No. 2018-13, <i>“Fair Value Measurement (Topic 820).” </i>The ASU modifies, removes and adds
several disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. ASU 2018-13 is effective for all
entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on
changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level
3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the
most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively
to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018-13. An entity is permitted
to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures
until their effective date. The Company is evaluating the effect ASU 2018-13 will have on its consolidated financial statements
and disclosures and has not yet determined the effect of the standard on its ongoing financial reporting at this time.</p>

the FASB issued ASU No. 2018-15, “<i>Intangibles </i>— <i>Goodwill and Other </i>— <i>Internal-Use
Software (Subtopic 350-40).”</i> The ASU provides for the recognition of an intangible asset for the costs of internal-use
software licenses included in a cloud computing arrangement. Costs of arrangements that do not include a software license should
be accounted for as a service contract and expensed as incurred. This ASU is effective for fiscal years beginning after December
15, 2019, with early adoption permitted. The ASU permits two methods of adoption: prospectively to all implementation costs incurred
after the date of adoption, or retrospectively to each prior reporting period presented. The Company is evaluating the effect
ASU 2018-15 will have on its consolidated financial statements and disclosures and has not yet determined the effect of the standard
on its ongoing financial reporting at this time.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">On March 31, 2017,
the Company signed a new 7-year lease for approximately 56,000 square feet in Monroe Township, New Jersey that will be used as
warehouse/production space and the Company’s principal offices and corporate headquarters. The lease was classified as an
operating lease. Rent payments relating to the Monroe premises are subject to annual increases. The minimum monthly payments will
vary over the 7-year term of the lease. The Company will record rent expense on a straight-line basis over the 7-year term of
the lease. The difference between rent expense and the monthly lease payment will go to a deferred rent/prepaid rent account.
The Landlord has provided the Company a tenant improvement allowance in an amount up to, but not exceeding, $137,563 to be applied
to the cost of tenant improvement work. The Company collected the full amount of the tenant improvement allowance in May 2018.
The Company recorded lease incentive liability to deferred rent. With the Company’s adoption of ASU No. 2016-02 on May 1,
2019, the balances in lease incentive liability and deferred rent will be included in the value of the right of use asset.</p>

Guidance</b></p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"><b> </b></p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company adopted
the new revenue recognition guidance effective May 1, 2018, using the modified retrospective method. The primary impact of the
new guidance was a change in the timing of revenue recognition on certain long-term contracts. The new guidance does not change
the total sales or operating income on the related customer contracts, only the timing of when sales and operating income are recognized.
The Company uses the expected cost plus a margin approach and lease accounting literature for revenue recognition on customer contracts.
The impact of the adoption for the twelve months ended April 30, 2019 was an increase of $118,000 to net loss. Further, as the
Company’s adoption of the guidance decelerated the timing of revenue recognition on the Company’s contracts, the adoption
resulted in an $118,000 increase in the Company’s remaining performance obligations, also referred to as backlog, as of April
30, 2019.</p>

Recognition</i></b></p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">A performance obligation
is the unit of account for revenue recognition. The Company assesses the goods or services promised in a contract with a customer
and identifies as a performance obligation either: a) a good or service (or a bundle of goods or services) that is distinct; or
b) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer.
A contract may contain a single or multiple performance obligations. For contracts with multiple performance obligations, the Company
allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which
represents the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone
selling price based upon the facts and circumstances of each obligated good or service. The majority of the Company’s contracts
have no observable standalone selling price since the associated products and services are customized to customer specifications.
As such, the standalone selling price generally reflects the Company’s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The nature of the
Company’s contracts may give rise to several types of variable consideration, including claims and unpriced change orders;
awards and incentive fees; and liquidated damages and penalties. Variable consideration can also arise from modifications to the
scope of services. Variable consideration is included in the transaction price to the extent it is probable that a significant
reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved.
Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based
largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted)
that is reasonably available to us.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company recognizes
revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1) at a point
in time or (2) over time. A good or service is transferred when or as the customer obtains control of it. The evaluation of whether
control of each performance obligation is transferred at a point in time or over time is made at contract inception. Input measures
such as costs incurred or time elapsed are utilized to assess progress against specific contractual performance obligations for
the Company’s services. The selection of the method to measure progress towards completion requires judgment and is based
on the nature of the services to be provided. For the Company, the input method using costs incurred or time elapsed best represents
the measure of progress against the performance obligations incorporated within the contractual agreements. When the Company’s
estimate of total costs to be incurred to satisfy the performance obligations exceed revenue, the Company recognizes the loss immediately.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt">The Company classifies
leases as either operating or capital lease arrangements in accordance with the authoritative accounting guidance contained within
Accounting Standards Codification (“ASC”) Topic 840, <i>“Leases”.</i> At inception of the contract,
the Company evaluates the lease against the four lease classification criteria within ASC Topic 840. In general, if one of the
four criteria is met, then the lease is accounted for as a capital lease. All others are treated as an operating lease. For operating
leases, lessee payments are recorded to revenue on a straight-line basis over the term of the lease.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27.5pt"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company’s
contracts are either cost plus or fixed price contracts. Under cost plus contracts, customers are billed for actual expenses incurred
plus an agreed-upon fee. Under cost plus contracts, a profit or loss on a project is recognized depending on whether actual costs
are more or less than the agreed upon amount.</p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"> </p>
<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt">The Company has two
types of fixed price contracts, firm fixed price and cost-sharing. Under firm fixed price contracts, the Company receives an agreed-upon
amount for providing products and services specified in the contract, a profit or loss is recognized depending on whether actual
costs are more or less than the agreed upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer
is only intended to fund a portion of the costs on a specific project. Under cost sharing contracts, an amount corresponding to
the revenue is recorded in cost of revenues, resulting in gross profit on these contracts of zero. The Company’s share of

for warrants issued in connection with its public offerings in accordance with the guidance on “Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity” in Topic 480 which provides that warrants meeting the classification
of a liability award are recorded as a liability at its fair value. The warrant liabilities are subject to re-measurement at each
balance sheet date using the Black-Scholes option pricing model. The Company recognizes any change in fair value in its consolidated
statements of operations within “Gain due to the change in fair value of warrant liabilities”. The Company will continue
to adjust the carrying value of the warrants for changes in the estimated fair value until such time as these instruments are
exercised or expire. At that time, the liabilities will be reclassified to “Additional paid-in capital”, a component
of “Stockholders’ equity” on the Consolidated Balance Sheets. The warrants issued in connection with the Company’s
public offerings in June and July 2016 met the criteria of a liability award and were classified in warrant liabilities. The pre-funded
and common warrants issued in the Company’s April 8, 2019 public offering did not meet the criteria to be classified as
a liability award and therefore were treated as an equity award.</p>

rates expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carry
forwards are expected to be recovered, settled or utilized. 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.</p>
