Treatment Segment of our Company maintains a backlog of stored waste, which represents waste that has not been processed. The
backlog is principally a result of the timing and complexity of the waste being brought into the facilities and the selling price
per container. At December 31, 2017, our Treatment Segment had a backlog of approximately $7,666,000, as compared to approximately
$5,250,000 at December 31, 2016. Additionally, the time it takes to process waste from the time it arrives may increase due to
the types and complexities of the waste we are currently receiving. We typically process our backlog during periods of low waste
receipts, which historically has been in the first or fourth quarters.</FONT></P>

which has licensed disposal capabilities for low level radioactive waste in Andrews, TX, is also a competitor in the treatment
market with increasing market share. Perma-Fix now has two options for disposal of treated nuclear waste and thus mitigates prior
risk of ES providing the only outlet for disposal. The Treatment Segment treats and disposes of DOE generated wastes largely at
DOE owned sites. Smaller competitors are also present in the market place; however, we believe they do not present a significant
challenge at this time. Our Treatment Segment currently solicits business primarily on a North American basis with both government

Services Segment is engaged in highly competitive businesses in which a number of our government contracts and some of our commercial

we face is also often influenced by the project specification being bid on and the different specialty skill sets of each bidder
for which our Services Segment competes, especially projects subject to the governmental bid process. We also have the ability
to prime federal government small business procurements (small business set asides). Based on past experience, we believe that
large businesses are more willing to team with small businesses in order to be part of these often substantial procurements. There
are a number of qualified small businesses in our market that will provide intense competition that may provide a challenge to
our ability to maintain strong growth rates and acceptable profit margins. For international business there are additional competitors,
many from within the country the work is to be performed, making winning work in foreign countries more challenging. If our Services
Segment is unable to meet these competitive challenges, it could lose market share and experience an overall reduction in its
profits.</FONT></P>

adverse effect on us, our operations and financial condition. In addition to various federal, state and local environmental regulations,
our hazardous waste transportation activities are regulated by the U.S. Department of Transportation, the Interstate Commerce

be affected by any law or rule that may be enacted or enforced in the future, or any new or different interpretations of existing

material amount of our Treatment and Services Segments&rsquo; revenues are generated through various U.S. government contracts

are awarded through a regulated competitive bidding process. Some government contracts are awarded to multiple competitors, which

under these government contracts. All contracts with, or subcontracts involving, the federal government are terminable, or subject
to renegotiation, by the applicable governmental agency on 30 days notice, at the option of the governmental agency. If we fail

Atomic Energy Act of 1954, as amended, or the AEA, comprehensively regulates the manufacture, use, and storage of radioactive

to DOE contractors for liabilities arising out of nuclear incidents at DOE nuclear facilities. That indemnification protects DOE
prime contractor, but also similar companies that work under contract or subcontract for a DOE prime contract or transporting
radioactive material to or from a site. The indemnification authority of the DOE under the PAA was extended through 2025 by the
Energy Policy Act of 2005.</FONT></P>

than we do, which can give them a competitive advantage. In addition, even if we are qualified to work on a new government contract,
we might not be awarded the contract because of existing government policies designed to protect certain types of businesses and
under-represented minority contractors. Although the Company has the ability to certify and bid government contract as a small
business, there are a number of qualified small businesses in our market that will provide intense competition. For international
business, which we continue to focus on, there are additional competitors, many from within the country the work is to be performed,
making winning work in foreign countries more challenging. Competition places downward pressure on our contract prices and profit
margins. If we are unable to meet these competitive challenges, we could lose market share and experience on overall reduction
in our profits.</FONT></P>

M&amp;EC facility is schedule to close by the end of the second quarter of 2018. Our strategic plan includes the process
of transitioning waste shipments and operational capabilities to our other Treatment Segment facilities, subject to customer requirements
and regulatory approvals. Simultaneously, we continue with closure and decommissioning activities in accordance with M&amp;EC&rsquo;s
license and permit requirements. We believe that the pending closure of our M&amp;EC facility in Oak Ridge, Tennessee should reduce
our fixed costs within our Treatment Segment with minimal loss in revenue, thereby improving our Treatment Segment gross margin.
However, as certain waste shipments are dependent on our customers&rsquo; requirements and the operational capabilities of our
other Treatment facilities to accept and treat these wastes, there are no guarantees that our other Treatment facilities will
be able to treat these wastes. In such event, our financial results could be materially impacted.</FONT></P>

If we are unable to maintain adequate internal control over financial reporting or effectively remediate any material weakness
identified in internal control over financial reporting, there is a reasonable possibility that a misstatement of our annual or
interim financial statements will not be prevented or detected in a timely manner. If we cannot produce reliable financial reports,
investors could lose confidence in our reported financial information, the market price of our common stock could decline significantly,

2017 that there was a breach of our existing security procedures and policies as to employee information due to an employee&rsquo;s
error in not following our existing security procedures and policies, we do not believe this breach had a material adverse effect

became an interested stockholder, unless the business combination is approved in a prescribed manner. As a result of Section 203,
potential acquirers may be discouraged from attempting to effect acquisition transactions with us, thereby possibly depriving
our security holders of certain opportunities to sell, or otherwise dispose of, such securities at above-market prices pursuant
to such transactions. Further, certain of our option plans provide for the immediate acceleration of, and removal of restrictions

decreased $1,450,000 or 2.8% to $49,769,000 for the twelve months ended December 31, 2017 from $51,219,000 for the corresponding
period of 2016. The decrease in revenue was primarily due to the decrease in revenue of approximately $6,947,000 or 36.6% from
$18,966,000 to $12,019,000 in the Services Segment. Treatment Segment revenue increased approximately $5,497,000 or 17.0% from
higher waste volume and higher averaged price waste resulting from revenue mix. Total gross profit increased $1,536,000 or 21.7%
for the twelve months ended December 31, 2017 as compared to the corresponding period of 2016 primarily due to higher revenue
generated from our Treatment Segment. Total selling, general and administrative (&ldquo;SG&amp;A&rdquo;) expenses increased $377,000

continue our plan to close our East Tennessess Materials and Energy Corporation (&ldquo;M&amp;EC&rdquo;) facility by the end of
the M&amp;EC&rsquo;s lease term which has been extended to June 30, 2018 from January 21, 2018. In accordance with Accounting
Standards Codification (&ldquo;ASC&rdquo;) 360, &ldquo;Property, Plant, and Equipment,&rdquo; during the third quarter of 2017,
we performed an updated financial valuation of M&amp;EC&rsquo;s remaining long-lived tangible assets (inclusive of the capitalized
asset retirement costs) for further potential impairment. Based on our analysis using an undiscounted cash flow approach, we concluded
that the carrying value of the remaining tangible assets for M&amp;EC was not recoverable and exceeded its fair value. Consequently,
we fully impaired the remaining tangible assets for M&amp;EC resulting in $672,000 in tangible asset impairment loss (non-cash).
During 2017, we also recorded an additional $1,400,000 in closure liabilities due to a change in estimated closure costs for our
M&amp;EC facility. M&amp;EC revenues were approximately $6,312,000 and $4,419,000 for the years ended December 31, 2017 and 2016,
respectively. Upon closure </FONT>of M&amp;EC, we estimate that we will eliminate annual fixed costs estimated to be
approximately $4,000,000 to $5,000,000.</P>

Treatment and Services Segments&rsquo; business continues to be heavily dependent on services that we provide to governmental
clients directly as the contractor or indirectly as a subcontractor. We believe demand for our services will continue to be subject
to fluctuations due to a variety of factors beyond our control, including the current economic conditions, the large budget deficit
that the government is facing, and the manner in which the government will be required to spend funding to remediate federal sites.
In addition, our governmental contracts and subcontracts relating to activities at governmental sites are generally subject to
termination or renegotiation on 30 days notice at the government&rsquo;s option. Significant reductions in the level of governmental
funding or specifically mandated levels for different programs that are important to our business could have a material adverse
impact on our business, financial position, results of operations and cash flows. As previously disclosed, during the latter part
of 2016, our Medical Segment reduced its research and development (&ldquo;R&amp;D&rdquo;) activities substantially due to the
need for capital to fund such activities. Our Medical Segment continues to seek various sources in order to raise this capital.
We anticipate that our Medical Segment R&amp;D activities will be limited until the necessary capital is obtained through its
own credit facility or additional equity raise. If the Medical Segment is unable to raise the necessary capital, the Medical Segment
could be required to further reduce, delay or eliminate its R&amp;D program.</FONT></P>

Segment revenue increased $5,497,000 or 17.0% for the year ended December 31, 2017 over the same period in 2016. The revenue increase
was primarily due to higher revenue generated from government clients of approximately $6,159,000 or 28.7% primarily due to higher
averaged price waste resulting from waste mix and higher waste volume. Other nuclear waste revenue decreased by approximately
$1,006,000 or 15.9% primarily due to both lower waste volume and lower averaged price waste. Services Segment revenue decrease
by $6,947,000 or 36.6% for the year ended December 31, 2017 over the same period in 2016 primarily due to the completion of a
nuclear services project in December 2016 which had generated revenues of approximately $9,763,000 in 2016. The decrease in revenue
in the Services Segment was also partially due to delays in a large nuclear services project in May 2017 due to government funding
uncertainties. This project commenced at the end of August 2017 and is expected to continue until approximately June 2018. Our
Services Segment revenues are project based; as such, the scope, duration and completion of each project vary. As a result, our
Services Segment revenues are subject to differences relating to timing and project value.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Cost
of goods sold for the Treatment Segment increased by $1,596,000 or approximately 5.7%. Costs of goods sold for the Treatment Segment
for 2017 included approximately $550,000 and $850,000 in additional closure costs recorded in the third and fourth quarters of
2017, respectively, in connection with the pending closure of our M&amp;EC facility as discussed above. Also, cost of goods sold
for the Treatment Segment for 2016 included a write-off of approximately $587,000 in prepaid fees recorded in the second quarter
of 2016 resulting from the impairment of certain equipment at our M&amp;EC facility due to the pending closure of the M&amp;EC
facility. Such fees were incurred for emission performance testing certification requirements as mandated by the state. Excluding
the additional closure costs of $1,400,000 recorded in 2017 and the write-off of $587,000 recorded in 2016, total Treatment Segment
cost of goods sold increased $783,000 or 2.8%. Treatment Segment variable costs increased by approximately $750,000 primarily
in disposal, transportation, material and supplies, and lab costs due to higher revenue. Treatment Segment overall fixed costs
were slightly higher by approximately $33,000 resulting from the following: maintenance expense was higher by $257,000; general
expense was higher by approximately $222,000 in various categories; regulatory expense was higher by $190,000; salaries and payroll
related expenses were lower by approximately $414,000 due to lower headcount from normal attrition and employees working on the
pending closure of the M&amp;EC facility (resulting in salaries and payroll related expenses charged to closure accrual); and
depreciation expense was lower by approximately $222,000 as we fully impaired the remaining tangible assets of our M&amp;EC facility
during the third quarter of 2017 resulting from an updated financial valuation of the remaining tangible assets at M&amp;EC due
to the pending closure of the facility by the end of June 2018. Services Segment cost of goods sold decreased $4,582,000
or 28.8% primarily due to the decrease in revenue as discussed above. The decrease in Services Segment&rsquo;s cost of goods sold
was primarily in salaries and payroll related expenses, travel, and outside services expenses totaling approximately $3,142,000
with the remaining decrease primarily in material and supplies and disposal costs. Included within cost of goods sold is depreciation
and amortization expense of $3,720,000 and $4,002,000 for the twelve months ended December 31, 2017, and 2016, respectively.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt; font-weight: normal">The
increase in total SG&amp;A was primarily due to higher SG&amp;A costs in the Services Segment. Services Segment SG&amp;A increased
by $698,000 primarily due to higher bad debt expenses of approximately $757,000. During the fourth quarter of 2017, we recorded
an additional $364,000 in bad debt expense in our Services Segment as certain accounts receivable were determined not to be collectible
at December 31, 2017. The increase in bad debt expenses in 2017 as compared to 2016 was also impacted by a reduction in bad debt
expense of approximately $364,000 we recorded during the second quarter of 2016 resulting from a reduction in allowance for doubtful
accounts as a previously uncertain account receivable was determined to be collectible at June 30, 2016. In addition, Services
Segment salaries and payroll related expenses were higher by approximately $49,000 and general expenses were higher by approximately
$15,000 in various categories. The overall higher costs in SG&amp;A in the Services Segment were partially offset by lower outside
services costs of approximately $71,000 resulting from fewer consulting/subcontract matters, lower depreciation expenses of $35,000
as certain fixed assets became fully depreciated at year end 2016, and lower travel expenses of $17,000. The decrease in Administrative
SG&amp;A was primarily the result of lower salaries and payroll related expenses of approximately $100,000 and lower amortization
expense of approximately $44,000 as we recorded a patent write-off during the second quarter of 2016. In addition, Administrative
SG&amp;A expenses were lower by approximately $29,000 in outside service expenses resulting from fewer subcontract/consulting
matters. The total decrease in Administrative SG&amp;A costs was partially offset by higher travel expenses of approximately $27,000
made by our executives and higher general expenses of $15,000 in various categories. Treatment SG&amp;A was lower primarily due
to lower salaries and payroll related costs of approximately $341,000. The lower costs in Treatment SG&amp;A were partially offset
by higher general expenses of $101,000 mostly due to higher tradeshow/marketing expenses and higher outside services expenses
of approximately $50,000 due to more consulting matters. Included in SG&amp;A expenses is depreciation and amortization expense
of $83,000 and $163,000 for the twelve months ended December 31, 2017 and 2016, respectively. </FONT></P>

due to lower interest from our declining term loan balance and lower average revolver loan balance outstanding.</FONT></P>

expense-financing fees decreased approximately $73,000 for the twelve months ended December 31, 2017 as compared to the corresponding
period of 2016. The decrease was primarily due to lower monthly amortized financing fees resulting from our amended credit facility
pursuant to the amendment dated March 24, 2016 as discussed above. The decrease was also the result of final amortization of debt
discount as financing fees which occurred in August 2016 in connection with the issuance of our common stock and two warrants
to certain lenders as consideration for the Company receiving a $3,000,000 loan which was paid off by the Company in August 2016.</FONT></P>

had income tax benefits of $1,285,000 and $2,994,000 for continuing operations for the years ended December 31, 2017 and 2016,
respectively. The Company&rsquo;s effective tax rates were approximately 26.6% and 18.4% for the twelve months ended December
31, 2017 and 2016, respectively. Our tax benefit for 2017 included a  tax benefit in the amount of approximately $1,695,000
recorded in the fourth quarter of 2017 resulting primarily from the required re-measurement of our deferred assets and liabilities
and the reversal of valuation allowance and refunding of alternative minimum tax (&ldquo;AMT&rdquo;) credit carryforward. This
tax benefit was recorded as a result of the Tax Cuts and Jobs Act of 2017 (the &ldquo;Tax Act&rdquo;) enacted into law on December
22, 2017 (see &ldquo;Critical Accounting Policies&rdquo; in this section for a further discussion of the Tax Act and the tax benefit
recorded). Our income tax benefit for the year ended 2016 was primarily the result of a tax benefit recorded in the amount of
approximately $3,203,000 resulting from the permit impairment loss recorded for the M&amp;EC subsidiary during the second quarter
of 2016.</FONT></P>

cash flow requirements during 2017 were primarily financed by our operations, credit facility availability, and the restricted
finite risk sinking funds that were released back to us in May 2017 from the cancellation of a previous financial assurance policy
issued by American International Group (&ldquo;AIG&rdquo;) for our Perma-Fix Northwest Richland, Inc. (&ldquo;PFNWR&rdquo;) subsidiary
(see &ldquo;Investing Activities&rdquo; below for further information of this finite sinking fund and the replacement closure
mechanism acquired for the PFNWR subsidiary). We anticipate that our cash flow requirements for the next twelve months will consist
primarily of general working capital needs, scheduled principal payments on our debt obligations, remediation projects, planned
capital expenditures, and closure spending requirements in the amount of approximately $2,791,000 in connection with the pending
closure of our M&amp;EC facility (&ldquo;M&amp;EC closure&rdquo;). We plan to fund these requirements from our operations and
our credit facility. Additionally, as a result of the M&amp;EC closure, we expect to receive during 2018, a partial release of
approximately $5,000,000 of the $15,676,000 restricted finite risk sinking funds held by AIG as collateral under the financial
assurance policy dated June 2003 that we currently have with AIG. This partial release in finite risk sinking funds is subject
to approval from AIG and the appropriate Tennessee state regulators and when released, will further enhance our liquidity. We
continue to explore all sources of increasing revenue. We are continually reviewing operating costs and are committed to further
reducing operating costs to bring them in line with revenue levels, when necessary. Although there are no assurances, we believe
that our cash flows from operations and our available liquidity from our credit facility are sufficient to fund our operations
for the next twelve months. Additionally, the partial release of the finite risk sinking funds that we expect to receive during
2018 as a result of the M&amp;EC closure as discussed above will further provide additional funding for our operations as needed.
As previously disclosed, during the latter part of 2016, our Medical Segment substantially reduced its R&amp;D activities due
to the need for capital to fund such activities. We anticipate that our Medical Segment will not resume full R&amp;D activities
until it obtains the necessary funding through obtaining its own credit facility or additional equity raise. Our Medical Segment
continues to seek various sources in order to raise this funding. If the Medical Segment is unable to raise the necessary capital,
the Medical Segment could be required to further reduce, delay or eliminate its R&amp;D program.</FONT></P>

2017, our purchases of capital equipment totaled approximately $439,000. These expenditures were primarily for improvements in
our Treatment Segment. These capital expenditures were funded by cash from operations. We have budgeted approximately $1,000,000
for 2018 capital expenditures for our Treatment and Services Segments to maintain operations and regulatory compliance requirements.
On March 7, 2018, our Board approved an additional $1,000,000 in capital spending for footprint expansion for one of our Treatment
Segment facilities. Certain of these budgeted projects may either be delayed until later years or deferred altogether. We have
traditionally incurred actual capital spending totals for a given year at less than the initial budgeted amount. We plan to fund
our capital expenditures from cash from operations and/or financing. The initiation and timing of projects are also determined
by financing alternatives or funds available for such capital projects.</FONT></P>

had a closure policy dated August 2007 for our PFNWR facility with AIG (&ldquo;PFNWR policy&rdquo;) which provided financial assurance
to the State of Washington in the event of closure of the PFNWR facility. In April 2017, we received final releases from state
and federal regulators for the PFNWR policy which enabled us to cancel the PFNWR policy resulting in the release of approximately
$5,951,000 on May 1, 2017 in finite sinking funds previously held by AIG as collateral for the PFNWR policy. We used the released
finite sinking funds to pay off our revolving credit with the remaining funds used for general working capital needs. We have
acquired new bonds in the required amount of approximately $7,000,000 (&ldquo;new bonds&rdquo;) to replace the PFNWR policy in
providing financial assurance for the PFNWR facility. Upon receipt of the $5,951,000 in finite sinking funds from AIG, we and
our lender executed a standby letter of credit in the amount of $2,500,000 as collateral for the new bonds for the PFNWR facility.</FONT></P>

Recognition Estimates. </I>We utilize a performance based methodology for purposes of revenue recognition in our Treatment Segment.
As we accept more complex waste streams in this segment, the treatment of those waste streams becomes more complicated and time
consuming. We have continued to enhance our waste tracking capabilities and systems, which has enabled us to better match the
revenue earned to the processing phases achieved using a proportional performance method. The major processing phases are receipt,
treatment/processing and shipment/final disposition. Upon receiving various wastes we recognize a certain percentage (generally
ranging from 9.0% to 33%) of revenue as we incur costs for transportation, analyses and labor associated with the receipt of mixed
waste. As the waste is processed, shipped and disposed of, we recognize the remaining revenue and the associated costs of transportation
and burial where applicable. We review and evaluate our revenue recognition estimates and policies on an annual basis.</FONT></P>

Environmental Obligations&rdquo; requires that the discounted fair value of a liability for an ARO be recognized in the period
in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition of an ARO
requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities,
timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate
to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then
discounted back, using a credit adjusted risk free rate, to the present value. ARO&rsquo;s are included within buildings as part
of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial
measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time
and revisions to either the timing or the amount of the original estimate of undiscounted cash flow. Increases in the ARO liability
due to passage of time impact net income as accretion expense and are included in cost of goods sold in the Consolidated Statements

routinely use third party disposal companies, who ultimately destroy or secure landfill residual materials generated at our facilities

remedial action; consequently, any party utilizing these sites may be liable for some or all of the remedial costs. Despite our

a potentially responsible party (&ldquo;PRP&rdquo;) at a remedial action site, which could have a material adverse effect.</FONT></P>

to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error
or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial
reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not
for the purpose of expressing an opinion on the effectiveness of the Company&rsquo;s internal control over financial reporting.
Accordingly, we express no such opinion.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Our
audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to
error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles
used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that our audits provide a reasonable basis for our opinion.</FONT></P>

receivable are customer obligations due under normal trade terms requiring payment within 30 or 60 days from the invoice date
based on the customer type (government, broker, or commercial). The carrying amount of accounts receivable is reduced by an allowance
for doubtful accounts, which is a valuation allowance that reflects management&rsquo;s best estimate of the amounts that will
not be collected. The Company regularly reviews all accounts receivable balances that exceed 60 days from the invoice date and
based on an assessment of current credit worthiness, estimates the portion, if any, of the balance that will not be collected.
This analysis excludes government related receivables due to our past successful experience in their collectability. Specific
accounts that are deemed to be uncollectible are reserved at 100% of their outstanding balance. The remaining balances aged over
60 days have a percentage applied by aging category, based on historical experience that allows us to calculate the total allowance
required. Once the Company has exhausted all options in the collection of a delinquent accounts receivable balance, which includes
collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible and subsequently
written off. The write off process involves approvals from senior management based on required approval thresholds.</FONT></P>

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Unbilled
receivables are generated by differences between invoicing timing and our proportional performance based methodology used for
revenue recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the
Company recognizes the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in
processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference between
completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing
differences occur for several reasons: partially from delays in the final processing of all wastes associated with certain work
orders and partially from delays for analytical testing that is required after the facilities have processed waste but prior to
our release of waste for disposal. The tasks relating to these delays usually take several months to complete. As the Company
now has historical data to review the timing of these delays, the Company realizes that certain issues, including, but not limited
to, delays at our third party disposal site, can extend collection of some of these receivables greater than twelve months. However,
our historical experience suggests that a significant portion of unbilled receivables are ultimately collectible with minimal
concession on our part. The Company, therefore, segregates the unbilled receivables between current and long-term.</FONT></P>

and equipment expenditures are capitalized and depreciated using the straight-line method over the estimated useful lives of the
assets for financial statement purposes, while accelerated depreciation methods are principally used for income tax purposes.
Generally, asset lives range from ten to forty years for buildings (including improvements and asset retirement costs) and three
to seven years for office furniture and equipment, vehicles, and decontamination and processing equipment. Leasehold improvements

closure costs represent our estimated environmental liability to clean up our facilities, as required by our permits, in the event

liability for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying
cost of the asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding
such factors as estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations,
and credit adjusted risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which
the closure will occur, and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&rsquo;s are
included within buildings as part of property and equipment and are depreciated over the estimated useful life of the property.
In periods subsequent to initial measurement of the ARO, the Company must recognize period-to-period changes in the liability
resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash
flows. Increases in the ARO liability due to passage of time impact net income as accretion expense, which is included in cost
of goods sold. Changes in costs resulting from changes or expansion at the facilities require adjustment to the ARO liability

Segment revenues.</I> The processing of mixed waste is complex and may take several months or more to complete; as such, the Treatment
Segment recognizes revenues using a proportional performance based methodology with its measure of progress towards completion
determined based on output measures consisting of milestones achieved and completed. The Treatment Segment has waste tracking
capabilities, which it continues to enhance, to allow for better matching of revenues earned to the processing phases achieved.
The revenues are recognized as each of the following three processing phases are completed: receipt, treatment/processing and
shipment/final disposal. However, based on the processing of certain waste streams, the treatment/processing and shipment/final
disposal phases may be combined as sometimes they are completed concurrently. As major processing phases are completed and the
costs are incurred, the Treatment Segment recognizes the corresponding percentage of revenue utilizing a proportional performance
model. The Treatment Segment experiences delays in processing invoices due to the complexity of the documentation that is required
for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon invoicing terms,
which results in unbilled receivables. The timing differences occur for several reasons, partially from delays in the final processing
of all wastes associated with certain work orders and partially from delays for analytical testing that is required after the
waste is processed but prior to our release of the waste for disposal. As the waste moves through these processing phases and
revenues are recognized, the correlating costs are expensed as incurred. Although the Treatment Segment uses its best estimates
and all available information to accurately determine these disposal expenses, the risk does exist that these estimates could
prove to be inadequate in the event the waste requires retreatment. Furthermore, should the waste be returned to the customer,
the related receivables could be uncollectible; however, historical experience has not indicated this to be a material uncertainty.</FONT></P>

based on their fair values. The Company accounts for stock-based compensation issued to consultants in accordance with the provisions
of ASC 505-50, &ldquo;Equity-Based Payments to Non-Employees.&rdquo; Measurement of stock-based payment transactions with consultants,
including options, is based on the fair value of whichever is more reliably measurable: (a) the goods or services received; or
(b) the equity instrument issued. The measurement date for the fair value of the stock-based payment transaction is determined
at the earlier of performance commitment date or performance completion date. The Company uses the Black-Scholes option-pricing
model to determine the fair-value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the
fair value of stock-based awards include the exercise price of the award, the expected term, the expected volatility of our stock
over the stock-based award&rsquo;s expected term, the risk-free interest rate over the award&rsquo;s expected term, and the expected
annual dividend yield. The Company accounts for forfeitures when they occur.</FONT></P>

May 2014, the FASB issued ASU No. 2014-09, &ldquo;Revenue from Contracts with Customers&rdquo; followed by a series of related
accounting standard updates (collectively referred to as &ldquo;Topic 606&rdquo;), which will supersede nearly all existing revenue
recognition guidance. Topic 606 provides a single, comprehensive revenue recognition model for all contracts with customers. Under
the new standard, a five-step process is utilized in order to determine revenue recognition, depicting the transfer of goods or
services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services.
Topic 606 also requires additional disclosure surrounding the nature, amount, timing and uncertainty of revenue and cash flows
arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred
to obtain or fulfill a contract. Topic 606 is effective for annual reporting periods beginning after December 15, 2017 (including
interim reporting periods within those periods). The new standard permits two implementation approaches: the full retrospective
method, in which case 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, or the modified retrospective method, in which case the cumulative
effect of applying the standard would be recognized at the date of initial application. The Company has completed the evaluation
of customer contracts and continues to identify and implement appropriate changes to our business policies, processes, systems
and controls to support the adoption, recognition and disclosures under the new standard. The Company will adopt the new revenue
standard in the first quarter of 2018 applying the modified retrospective method. Based on our evaluation, we do not believe that
the adoption of ASU 2014-09 will result in a significant change in accounting principles applied to the Company&rsquo;s financial
position, results of operations or cash flows. We believe that revenue will continue to be generally recognized consistent with
our current revenue recognition model. The potential future impacts would be limited to the capitalization of direct and incremental
contract acquisition costs, which have not historically been material. The Company will continue to monitor the materiality of
these contract acquisition costs on an ongoing basis to determine if these costs become material and should be capitalized. In
accordance with the new standard, the Company will expand revenue recognition disclosures beginning in the first quarter of 2018
to address the new qualitative and quantitative requirements.</FONT></P>

is required to complete certain clean-up/maintenance activities at its facility pursuant to its permit requirements. The extent
and cost of these activities are determined by federal/state mandate requirements. The Company performed an analysis and related
estimate of the cost to complete the closure activities in accordance with its permit requirements during the second quarter of
2016 and based on this analysis, the Company recorded an additional $1,626,000 in closure liabilities with a corresponding increase
to capitalized ARO costs, which were being depreciated over the remaining term of the lease. The capitalized ARO costs were reported
as a component of &ldquo;Net Property and equipment&rdquo; in the Consolidated Balance Sheets.</FONT></P>

accordance with ASC 360, &ldquo;Property, Plant, and Equipment,&rdquo; the Company performed an updated financial valuation of
M&amp;EC&rsquo;s long-lived tangible assets during the second quarter of 2016, inclusive of the capitalized ARO costs, for potential
impairment. Based on our analysis using an undiscounted cash flows approach, the Company concluded that the carrying value of
certain tangible assets (property and equipment) for M&amp;EC was not recoverable and exceeded its fair value. Consequently, the
Company recorded $1,816,000 in tangible asset impairment loss in the second quarter of 2016. The Company also reevaluated the
estimated useful lives of the remaining tangible assets and as a result of this analysis, reduced the current estimated useful
lives of these assets ranging from 2 to 28 years at June 30, 2016 to 1.6 years, the remaining term of the lease. Accordingly,
the Company was depreciating the carrying value of M&amp;EC&rsquo;s remaining tangible assets of approximately $4,728,000 at June
30, 2016 over a period of approximately 1.6 years, which was to the original lease expiration date of January 21, 2018.</FONT></P>

fair value. Consequently, the Company fully impaired the remaining tangible assets at M&amp;EC resulting in a tangible asset impairment
loss of $672,000. Additionally, during the third and fourth quarters of 2017, the Company recorded an additional $550,000 and

Company adopted the 2003 Outside Directors Stock Plan (the &ldquo;2003 Plan&rdquo;), which was approved by our stockholders at
the Annual Meeting of Stockholders on July 29, 2003. Options granted under the 2003 Plan generally have a vesting period of six
months from the date of grant and a term of 10 years, with an exercise price equal to the closing trade price on the date prior
to grant date. The 2003 Plan also provides for the issuance to each outside director a number of shares of the Company&rsquo;s
Common Stock in lieu of 65% or 100% (based on option elected by each director) of the fee payable to the eligible director for
services rendered as a member of the Board of Directors (&ldquo;Board&rdquo;). The number of shares issued is determined at 75%
of the market value as defined in the plan. The 2003 Plan, as amended, also provides for the grant of an option to purchase up
to 6,000 shares of Common Stock for each outside director upon initial election to the Board, and the grant of an option to purchase
2,400 shares of Common Stock upon each re-election. At the Annual Meeting of Stockholders held on July 27, 2017 (&ldquo;2017 Annual
Meeting&rdquo;), the Company&rsquo;s stockholders approved an amendment to the 2003 Plan which authorized the issuance of an additional
300,000 shares of the Company&rsquo;s Common Stock under the plan. After the approval of the amendment, the number of shares of
the Company&rsquo;s Common Stock authorized under the 2003 Plan was 1,100,000. At December 31, 2017, the 2003 Plan had available
for issuance approximately 391,215 shares.</FONT></P>

Non-Qualified Stock Options (&ldquo;NQSOs&rdquo;) and Incentive Stock Options (&ldquo;ISOs&rdquo;) to officers and employees of
the Company for the purchase of up to 200,000 shares of the Company&rsquo;s Common Stock. The term of each stock option granted
is to be fixed by the Compensation and Stock Option Committee (the &ldquo;Compensation Committee&rdquo;), but no stock option
is exercisable more than ten years after the grant date, or in the case of an incentive stock option granted to a 10% stockholder,
five years after the grant date. The exercise price of any ISO granted under the 2010 Plan to an individual who is not a 10% stockholder
at the time of the grant is not to be less than the fair market value of the shares at the time of the grant, and the exercise
price of any incentive stock option granted to a 10% stockholder is not to be less than 110% of the fair market value at the time
of grant. The exercise price of any NQSOs granted under the plan is not to be less than the fair market value of the shares at
the time of grant. As discussed below, as the result of the approval of the 2017 Stock Option Plan (&ldquo;2017 Plan&rdquo;) at
the Company&rsquo;s 2017 Annual Meeting, no further options remain available for issuance under the 2010 Plan immediately upon
the approval of the 2017 Plan; however, the 2010 Plan remains in full force and effect with respect to the outstanding options
issued and unexercised at the date of the approval of the 2017 Plan which consisted of an option for the purchase of up to 10,000

September 8, 2017, Mark Duff succeeded Dr. Louis Centofanti as the CEO with Dr. Louis Centofanti serving as EVP of Strategic Initiatives
and continuing to serve as a member of the Board (see &ldquo;Note 15 &ndash; Related Party Transaction for further detail of this
transition&rdquo;). The share covered by each ISO granted has a contractual term of six years with one-fifth yearly vesting over
a five year period. The exercise price of each share covered by the ISO was $3.65 per share, which was equal to the fair market
value of the Company&rsquo;s Common Stock on the date of grant. At December 31, 2017, the 2017 Plan had an additional 130,000
shares of the Company&rsquo;s Common Stock available for the granting of additional options.</FONT></P>

Company issued a total of 61,598 and 55,793 shares of our Common Stock in 2017 and 2016, respectively, under our 2003 Plan to
our outside directors as compensation for serving on our Board. As a member of the Board, each director elects to receive either
65% or 100% of the director&rsquo;s fee in shares of our Common Stock. The number of shares received is calculated based on 75%
of the fair market value of our Common Stock determined on the business day immediately preceding the date that the quarterly
fee is due. The balance of each director&rsquo;s fee, if any, is payable in cash. The Company recorded approximately $234,000
and $233,000 in compensation expense (included in SG&amp;A) for the twelve months ended December 31, 2017 and 2016, respectively,
for the portion of director fees earned in the Company&rsquo;s Common Stock.</FONT></P>

sold or transferred, then each holder of a Right (other than the acquirer) will thereafter have the right to receive, upon exercise,

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">On
December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the &ldquo;Tax Act&rdquo;) was signed into law making significant changes
to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for
tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial
system, the elimination of alternative minimum tax (&ldquo;AMT&rdquo;) for corporations and a one-time transition tax on the mandatory
deemed repatriation of foreign earnings. As of December 31, 2017, the Company has estimated its provision for income taxes in
accordance with the Tax Act and guidance available resulting in the recognition of approximately $1,695,000 of income tax benefit
in the fourth quarter of 2017, the period in which the legislation was enacted. The  tax benefit of $1,695,000 consists
of $916,000 related to the re-measurement of deferred tax assets and liabilities, based on the rates at which they are expected
to reverse in the future and $779,000 related to the reversal of valuation allowance and refunding of AMT credit carryforwards.</FONT></P>

the Tax Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the
global intangible low-taxed income (&ldquo;GILTI&rdquo;) provisions and the base-erosion and anti-abuse tax (&ldquo;BEAT&rdquo;)

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable
return on the foreign subsidiary&rsquo;s tangible assets. The Company has elected to account for GILTI tax in the period in which
it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements for
the year ended December 31, 2017.</FONT></P>

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
BEAT provisions in the Tax Act eliminates the deduction of certain base-erosion payments made to related foreign corporations,
and imposes a minimum tax if greater than regular tax. The Company does not expect it will be subject to this tax and therefore
has not included any tax impacts of BEAT in its consolidated financial statements for the year ended December 31, 2017.</FONT></P>

Tax Act imposes a one-time transition tax on previously untaxed earnings and profits of foreign subsidiaries. As of December 31,
2017, the Company has current and accumulated deficits in earnings and profits for all of its foreign subsidiaries. As such, the
Company does not expect any exposure to the one-time transition tax.</FONT></P>

Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary
differences are expected to be recovered or paid. Accordingly, the Company&rsquo;s deferred tax assets and liabilities were re-measured
to reflect the reduction in the U.S. corporate income tax rate from 34% to 21%, resulting in a deferred tax benefit of $916,000
for the year ended December 31, 2017 and a corresponding $916,000 decrease in net deferred tax liabilities as of December 31,
2017. This benefit is attributable to the Company being in a net deferred tax liability position at the time of re-measurement.</FONT></P>

Tax Act fully repeals the corporate alternative minimum tax beginning in 2018. Additionally, any AMT credits generated in prior
years will be refundable between 2018 and 2021. The Company had AMT credits in the amount of $779,000 that it was carrying with
a full valuation allowance. As a result of the Tax Act, the valuation allowance against these credits is reversed and the credits
are reclassified from a deferred tax asset to current and long-term tax receivables.</FONT></P>

Company has estimated net operating loss carryforwards (&ldquo;NOLs&rdquo;) for federal and state income tax purposes of approximately
$10,099,000 and $57,956,000, respectively, as of December 31, 2017. The estimated consolidated federal and state NOLs include
approximately $2,618,000 and $3,769,000, respectively, of our majority-owned subsidiary, PF Medical, which is not part of our
consolidated group for tax purposes. These net operating losses can be carried forward and applied against future taxable income,
if any, and expire in various amounts starting in 2021. However, as a result of various stock offerings and certain acquisitions,
which in the aggregate constitute a change in control, the use of these NOLs will be limited under the provisions of Section 382
of the Internal Revenue Code of 1986, as amended. Additionally, NOLs may be further limited under the provisions of Treasury Regulation

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
Company has a 25-year finite risk insurance policy entered into in June 2003 (&ldquo;Master Closure Policy&rdquo;) with AIG, which
provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The Master
Closure Policy, as amended, provides for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual
inflation and other performance and surety bond requirements. All of the required payments for this Master Closure Policy, as
amended, were made by 2012. At December 31, 2017, our financial assurance coverage amount under this Master Closure Policy totaled
approximately $29,473,000, which included a reduction in financial assurance requirement of approximately $9,711,000 for our DSSI
subsidiary made during the fourth quarter of 2016 resulting from a recalculation the state mandated closure requirement. The Company
has recorded $15,676,000 and $15,546,000 in sinking fund related to this policy in other long term assets on the accompanying
Consolidated Balance Sheets at December 31, 2017 and 2016, respectively, which includes interest earned of $1,205,000 and $1,075,000
on the sinking fund as of December 31, 2017 and 2016, respectively. Interest income for the years ended 2017 and 2016 was approximately
$130,000 and $86,000, respectively. If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the
sinking fund account balance in return for complete release of liability from both us and any applicable regulatory agency using
this policy as an instrument to comply with financial assurance requirements.</FONT></P>

Company also had a finite risk insurance policy dated August 2007 for our PFNWR facility with AIG (&ldquo;PFNWR policy&rdquo;)
which provided financial assurance to the State of Washington in the event of closure of the PFNWR facility. The Company had recorded
$5,941,000 in finite risk sinking funds at December 31, 2016 in other long term assets on the accompanying Consolidated Balance
Sheets which included interest earned of $241,000 on the sinking fund. In April 2017, the Company received final releases from
state and federal regulators for the PFNWR policy which enabled the Company to cancel the PFNWR policy resulting in the release
of approximately $5,951,000 on May 1, 2017 in finite sinking funds previously held by AIG as collateral for the PFNWR policy.
The Company used the released finite sinking funds to pay off our revolving credit with the remaining funds used for general working
capital needs. The Company has acquired new bonds in the required amount of approximately $7,000,000 (&ldquo;new bonds&rdquo;)
to replace the PFNWR policy in providing financial assurance for the PFNWR facility. Upon receipt of the $5,951,000 in finite
sinking funds from AIG, the Company and its lender executed a standby letter of credit in the amount of $2,500,000 as collateral
for the new bonds for the PFNWR facility. In addition, the Company&rsquo;s lender imposed an additional $750,000 restriction on
the Company&rsquo;s borrowing availability pursuant to a &ldquo;Condition Subsequent&rdquo; clause in an amendment that the Company
entered into with its lender in the latter part of 2016. Interest income earned under the PFNWR policy for the years ended December
2017 and 2016 was approximately $10,000 and $21,000, respectively.</FONT></P>

<P STYLE="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">On
January 19, 2017, our Board and the Compensation Committee approved individual MIP for each Mark Duff, Ben Naccarato, and Dr.
Louis Centofanti. Each MIP is effective January 1, 2017 and applicable for the year ended December 31, 2017. Each MIP provides
guidelines for the calculation of annual cash incentive based compensation, subject to Compensation Committee oversight and modification.
Each MIP awards cash compensation based on achievement of performance thresholds, with the amount of such compensation established
as a percentage of the executive&rsquo;s 2017 annual base salary on the approval date of the MIP. The potential target performance
compensation ranges approved was from 5% to 100% ($13,962 to $279,248) of the base salary for Dr. Louis Centofanti, EVP of Strategic
Initiatives effective September 8, 2017 and previously the CEO and President; 5% to 100% ($13,350 to $267,000) of the base salary
for Mark Duff, CEO and President effective September 8, 2017 and previously the EVP/COO; and 5% to 100% ($11,033 to $220,667)
of the base salary for Ben Naccarato, CFO. Pursuant to the MIPs, the Compensation Committee had the right to modify, change or
terminate the MIPs at any time and for any reason. No performance compensation was earned or payable under each of the 2017 MIPs
as discussed above.</FONT></P>

awards cash compensation based on achievement of performance thresholds, with the amount of such compensation established as a
percentage of the executive&rsquo;s annual 2018 base salary on the approval date of the MIP. The potential target performance
compensation ranges from 5% to 100% of the 2018 base salary for the CEO ($13,350 to $267,000), 5% to 100% of the 2018 base salary

                                         over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of
                                         the Securities Exchange Act of 1934. Internal control over financial reporting is designed
                                         to provide reasonable assurance regarding the reliability of financial reporting and
                                         the preparation of financial statements for external purposes in accordance with accounting
                                         principles generally accepted in the United States of America. Because of its inherent
                                         limitations, internal control over financial reporting may not prevent or detect misstatements
                                         or fraudulent acts. Also, projections of any evaluation of effectiveness to future periods
                                         are subject to the risk that controls may become inadequate because of changes in conditions,

as calculated in accordance with Rule 13d-3 of the Exchange Act. Capital Bank has further informed us that its clients (and not
Capital Bank) maintain full voting and dispositive power over such shares. Consequently, Capital Bank has advised us that it believes
it is not the beneficial owner, as such term is defined in Rule 13d-3 of the Exchange Act, of the shares of our Common Stock registered
in the name of Capital Bank because it has neither voting nor investment power, as such terms are defined in Rule 13d-3, over

the representations of, or information provided by Capital Bank are incorrect or Capital Bank was historically acting on behalf
of its investors as a group, rather than on behalf of each investor independent of other investors, then Capital Bank and/or the

acquisition of 1,100 shares of our Preferred Stock that were convertible into a maximum of 256,560 shares of our Common Stock.
If either Capital Bank or a group of Capital Bank&rsquo;s investors became a beneficial owner of more than 10% of our Common Stock

CEO performance compensation was based upon meeting corporate revenue, EBITDA (earnings before interest, taxes, depreciation and
amortization), health and safety, and environmental compliance (permit and license violations) objectives during fiscal year 2017
from our continuing operations (excluding PF Medical). The Compensation Committee believes performance compensation payable under
each of the 2017 MIPs as discussed herein and below should be based on achievement of an EBITDA target, which excludes certain
non-cash items, as this target provides a better indicator of operating performance. However, EBITDA has certain limitations as
it does not reflect all items of income or cash flows that affect the Company&rsquo;s financial performance under GAAP. At achievement
of 70% to 119% of the revenue and EBITDA targets, the potential performance compensation was payable at 5% to 50% of the CEO&rsquo;s
2017 base salary. For this compensation, 60% was based on the EBITDA goal, 10% on the revenue goal, 15% on the number of health
and safety claim incidents that occurred during fiscal year 2017, and the remaining 15% on the number of notices alleging environmental,
health, or safety violations under our permits or licenses that occurred during the fiscal year 2017. At achievement of 120% to
160%+ of the revenue and EBITDA targets, the potential performance compensation was payable at 65% to 100% of the CEO&rsquo;s
2017 base salary. For this compensation, the amount payable was based on the four objectives noted above, with the payment of
such performance compensation being weighted more heavily toward the EBITDA objective. Each of the revenue and EBITDA components
was based on our Board-approved revenue target and EBITDA target. The 2017 target performance incentive compensation for our CEO
was as follows:</FONT></P>

EVP/COO performance compensation was based upon meeting corporate revenue, EBITDA, health and safety, and environmental compliance
(permit and license violations) objectives during fiscal year 2017 from our continuing operations (excluding PF Medical). At achievement
of 70% to 119% of the revenue target and 60% to 119% of the EBITDA target, the potential performance compensation was payable
at 5% to 50% of the 2017 base salary. For this compensation, 60% was based on EBITDA goal, 10% on revenue goal, 15% on the number
of health and safety claim incidents that occurred during fiscal year 2017, and the remaining 15% on the number of notices alleging
environmental, health or safety violations under our permits or licenses that occurred during the fiscal year 2017. Upon achievement
of 120% to 160%+ of the revenue and EBITDA targets, the potential performance compensation was payable at 65% to 100% of the EVP/COO&rsquo;s
2017 base salary. For this compensation, the amount payable was based on the four objectives noted above, with the payment of
such performance compensation being weighted more heavily toward the EBITDA objective. Each of the revenue and EBITDA components
was based on our Board-approved revenue target and EBITDA target. The 2017 target performance incentive compensation for our EVP/COO
was as follows:</FONT></P>

CFO performance compensation was based upon meeting corporate revenue, EBITDA, health and safety, and environmental compliance
(permit and license violations) objectives during fiscal year 2017 from our continuing operations (excluding PF Medical). At achievement
of 70% to 119% of the revenue and EBITDA targets, the potential performance compensation was payable at 5% to 50% of the 2017
base salary. For this compensation, 60% was based on EBITDA goal, 10% on revenue goal, 15% on the number of health and safety
claim incidents that occurred during fiscal year 2017, and the remaining 15% on the number of notices alleging environmental,
health or safety violations under our permits or licenses that occurred during the fiscal year 2017. Upon achievement of 120%
to 160%+ of the revenue and EBITDA targets, the CFO&rsquo;s potential performance compensation was payable at 65% to 100% of the
CFO&rsquo;s 2017 base salary. For this compensation, the amount payable was based on the four objectives noted above, with the
payment of such performance compensation being weighted more heavily toward the EBITDA objective. Each of the revenue and EBITDA
components was based on our Board-approved revenue target and EBITDA target. The 2017 target performance incentive compensation
for our CFO was as follows:</FONT></P>

discussed above, 2017 MIPs approved for the CEO, EVP/COO, and CFO by the Board and the Compensation Committee provided for the
award of cash compensation based on achievement of performance targets which included revenue and EBITDA targets as approved by
our Board. The 2017 MIP revenue target of $80,000,000 and EBITDA target of $9,300,000 were set by the Compensation Committee taking
into account the Board-approved budget for 2017 as well as the committee&rsquo;s expectations for performance that in its estimation
would warrant payment of incentive cash compensation. In formulating the revenue target of $80,000,000, the Board considered 2016
results, current economic conditions, and forecasts for 2017 government (U.S DOE) spending. The Compensation Committee believed
the performance targets were likely to be achieved, but not assured. No cash incentive-based compensation was paid under any of
the 2017 MIPs.</FONT></P>

CEO performance compensation is based upon meeting corporate revenue, EBITDA, health and safety, and environmental compliance
(permit and license violations) objectives during fiscal year 2018 from our continuing operations (excluding PF Medical). The
Compensation Committee believes performance compensation payable under each of the 2018 MIPs as discussed herein and below should
be based on achievement of an EBITDA target, which excludes certain non-cash items, as this target provides a better indicator
of operating performance. However, EBITDA has certain limitations as it does not reflect all items of income or cash flows that
affect the Company&rsquo;s financial performance under GAAP. At achievement of 60% to 110% of each of the revenue and EBITDA targets,
the potential performance compensation is payable at 5% to 50% of the 2018 base salary. For this compensation, 60% is based on
EBITDA goal, 10% on revenue goal, 15% on the number of health and safety claim incidents that occur during fiscal year 2018, and
the remaining 15% on the number of notices alleging environmental, health or safety violations under our permits or licenses that
occur during the fiscal year 2018. Upon achievement of 111% to 150%+ of each of the revenue and EBITDA targets, the potential
performance compensation is payable at 65% to 100% of the CEO&rsquo;s 2018 base salary. For this compensation, the amount payable
is based on the four objectives noted above, with the payment of such performance compensation being weighted more heavily toward
the EBITDA objective. Each of the revenue and EBITDA components is based on our Board-approved revenue target and EBITDA target.
The 2018 target performance incentive compensation for our CEO is as follows:</FONT></P>

CFO performance compensation is based upon meeting corporate revenue, EBITDA, health and safety, and environmental compliance
(permit and license violations) objectives during fiscal year 2018 from our continuing operations (excluding PF Medical). At achievement
of 60% to 110% of each of the revenue and EBITDA targets, the potential performance compensation is payable at 5% to 50% of the
2018 base salary. For this compensation, 60% is based on EBITDA goal, 10% on revenue goal, 15% on the number of health and safety
claim incidents that occur during fiscal year 2018, and the remaining 15% on the number of notices alleging environmental, health
or safety violations under our permits or licenses that occur during the fiscal year 2018. Upon achievement of 111% to 150%+ of
each of the revenue and EBITDA targets, the potential performance compensation is payable at 65% to 100% of the CFO&rsquo;s 2018
base salary. For this compensation, the amount payable is based on the four objectives noted above, with the payment of such performance
compensation being weighted more heavily toward the EBITDA objective. Each of the revenue and EBITDA components is based on our
Board-approved revenue target and EBITDA target. The 2018 target performance incentive compensation for our CFO is as follows:</FONT></P>

EVP of Strategic Initiatives performance compensation is based upon meeting corporate revenue, EBITDA, health and safety, and
environmental compliance (permit and license violations) objectives during fiscal year 2018 from our continuing operations (excluding
PF Medical). At achievement of 60% to 110% of each of the revenue and EBITDA targets, the potential performance compensation is
payable at 5% to 50% of the 2018 base salary. For this compensation, 60% is based on EBITDA goal, 10% on revenue goal, 15% on
the number of health and safety claim incidents that occur during fiscal year 2018, and the remaining 15% on the number of notices
alleging environmental, health or safety violations under our permits or licenses that occur during the fiscal year 2018. Upon
achievement of 111% to 150%+ of each of the revenue and EBITDA targets, the potential performance compensation is payable at 65%
to 100% of the EVP of Strategic Initiative&rsquo;s 2018 base salary. For this compensation, the amount payable is based on the
four objectives noted above, with the payment of such performance compensation being weighted more heavily toward the EBITDA objective.
Each of the revenue and EBITDA components is based on our Board-approved revenue target and EBITDA target. The 2018 target performance
incentive compensation for our EVP of Strategic Initiatives is as follows:</FONT></P>

provide for the award of cash compensation based on achievement of performance targets which included revenue and EBITDA targets
as approved by our Board. The 2018 MIP revenue target of $63,398,000 and EBITDA target of $7,682,000 were set by the Compensation
Committee taking into account the Board-approved budget for 2018 as well as the committee&rsquo;s expectations for performance
that in its estimation would warrant payment of incentive cash compensation. In formulating the revenue target of $63,398,000,
the Board considered 2017 results, current economic conditions, and forecasts for 2018 government (U.S DOE) spending. The Compensation
Committee believes the performance targets are likely to be achieved, but not assured.</FONT></P>

options granted include the exercise price of the award, the expected term, the expected volatility of the Company&rsquo;s stock
over the option&rsquo;s expected term, the risk-free interest rate over the option&rsquo;s expected term, and the expected annual
dividend yield. We recognize stock-based compensation expense using a straight-line amortization method over the requisite period,

believe that it is important for our directors to have a personal interest in our success and growth and for their interests to
be aligned with those of our stockholders; therefore, under our 2003 Outside Directors Stock Plan, as amended (&ldquo;2003 Outside
Directors Plan&rdquo;), each outside director is granted a 10-year option to purchase up to 6,000 shares of Common Stock on the
date such director is initially elected to the Board, and receives on each re-election date an option to purchase up to another
2,400 shares of our Common Stock, with the exercise price being the fair market value of the Common Stock preceding the option
grant date. No option granted under the 2003 Outside Directors Plan is exercisable until after the expiration of six months from
the date the option is granted and no option shall be exercisable after the expiration of ten years from the date the option is
granted. At December 31, 2017, options to purchase 154,800 shares of Common Stock were outstanding under the 2003 Outside Directors
Plan, of which 142,800 were vested at December 31, 2017.</FONT></P>

a member of the Board, each director may elect to receive either 65% or 100% of the director&rsquo;s fee in shares of our Common
Stock. The number of shares received by each director is calculated based on 75% of the fair market value of the Common Stock
determined on the business day immediately preceeding the date that the quarterly fee is due. The balance of each director&rsquo;s
fee, if any, is payable in cash. In 2017, the fees earned by our outside directors totaled approximately $298,000. Reimbursements
of expenses for attending meetings of the Board are paid in cash at the time of the applicable Board meeting. As a management
director, Dr. Centofanti is not eligible to participate in the 2003 Outside Directors Plan.</FONT></P>

as an agent of, certain of its accredited investors. As of the date of this report, Capital Bank has no warrants or options to
acquire, as agent for certain investors, additional shares of our Common Stocks. Although Capital Bank is the record holder of
the shares of Common Stock described in this note, Capital Bank has advised us that it does not believe it is a beneficial owner
of the Common Stock or that it is required to file reports under Section 16(a) or Section 13(d) of the Exchange Act. Because Capital
Bank (a) has advised us that it holds the Common Stock as a nominee only and that it does not exercise voting or investment power
over the Common Stock held in its name and that no one investor of Capital Bank for which it holds our Common Stock holds more
than 4.9% of our issued and outstanding Common Stock and (b) has not nominated, and has not sought to nominate, and does not intend
to nominate in the future, any person to serve as a member of our Board, we do not believe that Capital Bank is our affiliate.
Capital Bank&rsquo;s address is Burgring 16, A-8010 Graz, Austria.</FONT></P>

Common Stock is listed on the NASDAQ Capital Market. Rule 5605 of the NASDAQ Marketplace Rules requires a majority of a listed
company&rsquo;s board of directors to be comprised of independent directors. In addition, the NASDAQ Marketplace Rules require
that, subject to specified exceptions, each member of a listed company&rsquo;s audit, compensation and corporate governance and
nominating committees be independent under applicable provisions of the Exchange Act. Audit committee members must also satisfy
independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the
independence criteria set forth in Rule 10C-1 under the Exchange Act. Under NASDAQ Rule 5605(a)(2), a director will only qualify
as an &ldquo;independent director&rdquo; if, in the opinion of our Board, that person does not have a relationship that would
interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered
independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other
than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept,
directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries
or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for
purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors
specifically relevant to determining whether a director has a relationship to such company which is material to that director&rsquo;s
ability to be independent from management in connection with the duties of a compensation committee member, including, but not
limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such
company to the director; and whether the director is affiliated with the company or any of its subsidiaries or affiliates.</FONT></P>

Larry M. Shelton, Zach Wamp and Mark A. Zwecker is an &ldquo;independent director&rdquo; as defined under the NASDAQ Marketplace

The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a&#13;valuation allowance that reflects management&amp;#8217;s best estimate of the amounts that will not be collected. The Company regularly&#13;reviews all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit&#13;worthiness, estimates the portion, if any, of the balance that will not be collected. This analysis excludes government related&#13;receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible&#13;are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging&#13;category, based on historical experience that allows us to calculate the total allowance required. Once the Company has exhausted&#13;all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment,&#13;collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves&#13;approvals from senior management based on required approval thresholds.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Unbilled receivables are generated by differences&#13;between invoicing timing and our proportional performance based methodology used for revenue recognition purposes. As major processing&#13;and contract completion phases are completed and the costs are incurred, the Company recognizes the corresponding percentage of&#13;revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to the complexity of the documentation&#13;that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon&#13;invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially from delays&#13;in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that&#13;is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks relating to these&#13;delays usually take several months to complete. As the Company now has historical data to review the timing of these delays, the&#13;Company realizes that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection&#13;of some of these receivables greater than twelve months. However, our historical experience suggests that a significant portion&#13;of unbilled receivables are ultimately collectible with minimal concession on our part. The Company, therefore, segregates the&#13;unbilled receivables between current and long-term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Unbilled receivables within our Services Segment&#13;can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope, schedule,&#13;and cost to provide an objective measure of project progress) but invoice milestones have not yet been met and/or (2) contract&#13;claims and pending change orders, including Requests for Equitable Adjustments (&amp;#8220;REAs&amp;#8221;) when work has been performed&#13;and collection of revenue is reasonably assured.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Inventories&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Inventories consist of treatment chemicals,&#13;saleable used oils, and certain supplies. Additionally, the Company has replacement parts in inventory, which are deemed critical&#13;to the operating equipment and may also have extended lead times should the part fail and need to be replaced. Inventories are&#13;valued at the lower of cost or market with cost determined by the first-in, first-out method.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Property and Equipment &lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Property and equipment expenditures are capitalized&#13;and depreciated using the straight-line method over the estimated useful lives of the assets for financial statement purposes,&#13;while accelerated depreciation methods are principally used for income tax purposes. Generally, asset lives range from ten to forty&#13;years for buildings (including improvements and asset retirement costs) and three to seven years for office furniture and equipment,&#13;vehicles, and decontamination and processing equipment. Leasehold improvements are capitalized and amortized over the lesser of&#13;the term of the lease or the life of the asset. Maintenance and repairs are charged directly to expense as incurred. The cost and&#13;accumulated depreciation of assets sold or retired are removed from the respective accounts, and any gain or loss from sale or&#13;retirement is recognized in the accompanying Consolidated Statements of Operations. Renewals and improvements, which extend the&#13;useful lives of the assets, are capitalized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In accordance with Accounting Standards Codification&#13;(&amp;#8220;ASC&amp;#8221;) 360, &amp;#8220;Property, Plant, and Equipment&amp;#8221;, long-lived assets, such as property, plant and equipment,&#13;are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be&#13;recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated&#13;undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated&#13;future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair&#13;value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying&#13;amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified&#13;as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet. See &amp;#8220;Note&#13;3 &amp;#8211; M&amp;#38;EC Facility&amp;#8221; for impairment charges incurred on tangible assets resulting from the pending closure of the&#13;M&amp;#38;EC facility.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our depreciation expense totaled approximately&#13;$3,429,000 and $3,717,000 in 2017 and 2016, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Intangible Assets&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Intangible assets consist primarily of the&#13;recognized value of the permits required to operate our business.

If the fair value of the asset is less than the carrying amount, we perform a quantitative&#13;test to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over&#13;its fair value. Significant judgments are inherent in these analyses and include assumptions for, among other factors, forecasted&#13;revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate&#13;long term discount rates.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;Impairment testing of our permits&#13;related to our Treatment reporting unit as of October 1, 2017 resulted in no impairment charges for the year ended December 31,&#13;2017.

Our goal is to discover, develop, and bring to market innovative ways to process&#13;waste that address unmet environmental needs and to develop new company service offerings. The Company conducts research internally&#13;and also through collaborations with other third parties. R&amp;#38;D costs consist primarily of employee salaries and benefits, laboratory&#13;costs, third party fees, and other related costs associated with the development and enhancement of new potential waste treatment&#13;processes and new technology and are charged to expense when incurred in accordance with ASC Topic 730, &amp;#8220;Research and Development.&amp;#8221;&#13;The Company&amp;#8217;s R&amp;#38;D expenses included approximately $1,141,000 and $1,489,000 for the years ended December 31, 2017 and&#13;2016, respectively, incurred by our Medical Segment in the R&amp;#38;D of its medical isotope production technology.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Accrued Closure Costs and Asset Retirement&#13;Obligations (&amp;#8220;ARO&amp;#8221;)&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accrued closure costs represent our estimated&#13;environmental liability to clean up our facilities, as required by our permits, in the event of closure. ASC 410, &amp;#8220;Asset&#13;Retirement and Environmental Obligations&amp;#8221; requires that the discounted fair value of a liability for an ARO be recognized&#13;in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition&#13;of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities,&#13;timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate&#13;to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then&#13;discounted back, using a credit adjusted risk free rate, to the present value. ARO&amp;#8217;s are included within buildings as part&#13;of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial&#13;measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time&#13;and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability&#13;due to passage of time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting&#13;from changes or expansion at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation&#13;expense, in accordance with the Company&amp;#8217;s depreciation policy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Income Taxes&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Income taxes are accounted for in accordance&#13;with ASC 740, &amp;#8220;Income Taxes.&amp;#8221; Under ASC 740, the provision for income taxes is comprised of taxes that are currently&#13;payable and deferred taxes that relate to the temporary differences between financial reporting carrying values and tax bases of&#13;assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable&#13;income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred tax assets&#13;and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC 740 requires that deferred income tax assets&#13;be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred income tax assets will&#13;not be realized. The Company regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable&#13;income. The Company considers projected future taxable income and ongoing tax planning strategies, then records a valuation allowance&#13;to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC 740 sets out a consistent framework for&#13;preparers to use to determine the appropriate recognition and measurement of uncertain tax positions. ASC 740 uses a two-step approach&#13;wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount of the benefit is then measured&#13;to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out disclosure requirements to&#13;enhance transparency of an entity&amp;#8217;s tax reserves. The Company recognizes accrued interest and income tax penalties related&#13;to unrecognized tax benefits as a component of income tax expense.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company reassesses the validity of our&#13;conclusions regarding uncertain income tax positions on a quarterly basis to determine if facts or circumstances have arisen that&#13;might cause us to change our judgment regarding the likelihood of a tax position&amp;#8217;s sustainability under audit.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Foreign Currency&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s foreign subsidiaries include&#13;PF UK Limited, PF Canada and PF Medical.

Concentration of credit risk with respect to accounts receivable is limited due to the Company&amp;#8217;s&#13;large number of customers and their dispersion throughout the United States as well as with the significant amount of work that&#13;we perform for the federal government as discussed above.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company had two government related customers&#13;whose net outstanding receivable balance represented 17.9% and 16.8% of the Company&amp;#8217;s total consolidated net accounts receivable&#13;at December 31, 2017.

These taxes and surcharges include, among others, universal service fund charges, sales,&#13;use, waste, and some excise taxes. In determining whether to include such taxes in its revenue and expenses, the Company assesses,&#13;among other things, whether it is the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where the&#13;Company does business. As the Company is merely a collection agent for the government authority in certain of our facilities, the&#13;Company records the taxes on a net basis and excludes them from revenue and cost of services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Treatment Segment revenues.&lt;/i&gt; The processing&#13;of mixed waste is complex and may take several months or more to complete; as such, the Treatment Segment recognizes revenues using&#13;a proportional performance based methodology with its measure of progress towards completion determined based on output measures&#13;consisting of milestones achieved and completed. The Treatment Segment has waste tracking capabilities, which it continues to enhance,&#13;to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized as each of the following&#13;three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However, based on the processing&#13;of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as sometimes they are completed&#13;concurrently. As major processing phases are completed and the costs are incurred, the Treatment Segment recognizes the corresponding&#13;percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences delays in processing invoices&#13;due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue&#13;recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for&#13;several reasons, partially from delays in the final processing of all wastes associated with certain work orders and partially&#13;from delays for analytical testing that is required after the waste is processed but prior to our release of the waste for disposal.&#13;As the waste moves through these processing phases and revenues are recognized, the correlating costs are expensed as incurred.&#13;Although the Treatment Segment uses its best estimates and all available information to accurately determine these disposal expenses,&#13;the risk does exist that these estimates could prove to be inadequate in the event the waste requires retreatment. Furthermore,&#13;should the waste be returned to the customer, the related receivables could be uncollectible; however, historical experience has&#13;not indicated this to be a material uncertainty.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Services Segment revenues&lt;/i&gt;. Revenue includes&#13;services performed under fixed price, time and material, and cost-reimbursement contracts. Revenues and costs associated with fixed&#13;price contracts are recognized using the percentage of completion (efforts expended) method. The Services Segment estimates its&#13;percentage of completion based on attainment of project milestones. Revenues and costs associated with time and material contracts&#13;are recognized as revenue when earned and costs are incurred.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under cost reimbursement contracts, the Services&#13;Segment is reimbursed for costs incurred plus a certain percentage markup for indirect costs, in accordance with contract provisions.&#13;Costs incurred in excess of contract funding may be renegotiated for reimbursement. The Services Segment also earns a fee based&#13;on the approved costs to complete the contract.

The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based&#13;awards which requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise&#13;price of the award, the expected term, the expected volatility of our stock over the stock-based award&amp;#8217;s expected term, the&#13;risk-free interest rate over the award&amp;#8217;s expected term, and the expected annual dividend yield.

Transition guidance included in certain issued but not yet adopted ASUs were also updated to reflect this&#13;update. This update is effective immediately. The adoption of ASU 2017-03 by the Company in the first quarter of 2017 did not have&#13;a material impact on the Company&amp;#8217;s financial position, results of operations and cash flows. The Company will revise its&#13;disclosures for the standards not yet adopted as required by ASU 2017-03 as the Company progresses through its impact assessments.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Recently Issued Accounting Standards &amp;#8211;&#13;Not Yet Adopted&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In May 2014, the FASB issued ASU No. 2014-09,&#13;&amp;#8220;Revenue from Contracts with Customers&amp;#8221; followed by a series of related accounting standard updates (collectively referred&#13;to as &amp;#8220;Topic 606&amp;#8221;), which will supersede nearly all existing revenue recognition guidance. Topic 606 provides a single,&#13;comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process is utilized&#13;in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects&#13;the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure&#13;surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant&#13;judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective&#13;for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The&#13;new standard permits two implementation approaches: the full retrospective method, in which case the standard would be applied&#13;to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest&#13;period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized&#13;at the date of initial application. The Company has completed the evaluation of customer contracts and continues to identify and&#13;implement appropriate changes to our business policies, processes, systems and controls to support the adoption, recognition and&#13;disclosures under the new standard. The Company will adopt the new revenue standard in the first quarter of 2018 applying the modified&#13;retrospective method. Based on our evaluation, we do not believe that the adoption of ASU 2014-09 will result in a significant&#13;change in accounting principles applied to the Company&amp;#8217;s financial position, results of operations or cash flows. We believe&#13;that revenue will continue to be generally recognized consistent with our current revenue recognition model. The potential future&#13;impacts would be limited to the capitalization of direct and incremental contract acquisition costs, which have not historically&#13;been material. The Company will continue to monitor the materiality of these contract acquisition costs on an ongoing basis to&#13;determine if these costs become material and should be capitalized. In accordance with the new standard, the Company will expand&#13;revenue recognition disclosures beginning in the first quarter of 2018 to address the new qualitative and quantitative requirements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In February 2016, the FASB issued ASU No. 2016-02,&#13;&amp;#8220;Leases (Topic 842).&amp;#8221; Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities&#13;on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for&#13;a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative&#13;information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty&#13;of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after&#13;December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with&#13;early adoption permitted.

Subsequently, in November&#13;2016, the FASB issued ASU 2016-18, &amp;#8220;Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB Emerging&#13;Issues Task Force,&amp;#8221; which clarifies the guidance on the cash flow classification and presentation of changes in restricted&#13;cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should&#13;be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the&#13;statement of cash flow. ASU 2016-15 and ASU 2016-18 are effective for annual reporting periods, and interim periods therein, beginning&#13;after December 15, 2017 and are effective January 1, 2018 for the Company.

Down round features are features of certain equity-linked instruments (or embedded features) that result&#13;in the strike price being reduced on the basis of the pricing of future equity offerings. When determining whether certain financial&#13;instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification&#13;when assessing whether the instrument is indexed to an entity&amp;#8217;s own stock. Part II of this update addresses the difficulty&#13;of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB&#13;Accounting Standards Codification and does not have an accounting effect.

In light of this event and our strategic review&#13;of operations within our Treatment Segment, the Company instituted a plan to close its M&amp;#38;EC facility located in Oak Ridge,&#13;Tennessee at the end of the lease term which has been extended to June 30, 2018. Operations at the M&amp;#38;EC facility are limited&#13;during the remaining term of the lease and the facility continues to transition waste shipments and operational capabilities to&#13;our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Simultaneously, the Company&#13;continues with closure and decommissioning activities in accordance with M&amp;#38;EC&amp;#8217;s license and permit requirements.

Based on this analysis, the Company concluded that impairment existed and subsequently determined that the permit&#13;for our M&amp;#38;EC subsidiary was fully impaired resulting in an intangible impairment loss of approximately $8,288,000.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;M&amp;#38;EC is required to complete certain clean-up/maintenance&#13;activities at its facility pursuant to its permit requirements. The extent and cost of these activities are determined by federal/state&#13;mandate requirements. The Company performed an analysis and related estimate of the cost to complete the closure activities in&#13;accordance with its permit requirements during the second quarter of 2016 and based on this analysis, the Company recorded an additional&#13;$1,626,000 in closure liabilities with a corresponding increase to capitalized ARO costs, which were being depreciated over the&#13;remaining term of the lease. The capitalized ARO costs were reported as a component of &amp;#8220;Net Property and equipment&amp;#8221;&#13;in the Consolidated Balance Sheets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In accordance with ASC 360, &amp;#8220;Property,&#13;Plant, and Equipment,&amp;#8221; the Company performed an updated financial valuation of M&amp;#38;EC&amp;#8217;s long-lived tangible assets&#13;during the second quarter of 2016, inclusive of the capitalized ARO costs, for potential impairment. Based on our analysis using&#13;an undiscounted cash flows approach, the Company concluded that the carrying value of certain tangible assets (property and equipment)&#13;for M&amp;#38;EC was not recoverable and exceeded its fair value. Consequently, the Company recorded $1,816,000 in tangible asset impairment&#13;loss in the second quarter of 2016. The Company also reevaluated the estimated useful lives of the remaining tangible assets and&#13;as a result of this analysis, reduced the current estimated useful lives of these assets ranging from 2 to 28 years at June 30,&#13;2016 to 1.6 years, the remaining term of the lease. Accordingly, the Company was depreciating the carrying value of M&amp;#38;EC&amp;#8217;s&#13;remaining tangible assets of approximately $4,728,000 at June 30, 2016 over a period of approximately 1.6 years, which was to the&#13;original lease expiration date of January 21, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In the second quarter of 2016, the Company&#13;also wrote-off approximately $587,000 in fees previously incurred relating to emission performance testing certification requirement&#13;in order to meet state compliance mandate in connection with certain M&amp;#38;EC equipment which was impaired. Such amount had been&#13;previously included in &amp;#8220;Prepaid and other assets&amp;#8221; on the Consolidated Balance Sheets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the third quarter of 2017, the Company&#13;performed an updated financial valuation of M&amp;#38;EC&amp;#8217;s remaining long-lived tangible assets (inclusive of ARO costs) for&#13;further potential impairment. Based on our analysis using an undiscounted cash flow approach, the Company concluded that the carrying&#13;value of the remaining tangible assets for M&amp;#38;EC was not recoverable and exceeded its fair value. Consequently, the Company&#13;fully impaired the remaining tangible assets at M&amp;#38;EC resulting in a tangible asset impairment loss of $672,000. Additionally,&#13;during the third and fourth quarters of 2017, the Company recorded an additional $550,000 and $850,000, respectively, in closure&#13;costs and current closure costs liabilities due to change in estimated closure costs.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the years ended December 31, 2017 and&#13;2016, M&amp;#38;EC&amp;#8217;s revenues were approximately $6,312,000 and $4,419,000, respectively.&lt;/p&gt;</us-gaap:PropertyPlantAndEquipmentAndIntangibleAssetsTextBlock>

Options granted under the 2003 Plan generally have a vesting period of six months from the date of grant and a term of&#13;10 years, with an exercise price equal to the closing trade price on the date prior to grant date. The 2003 Plan also provides&#13;for the issuance to each outside director a number of shares of the Company&amp;#8217;s Common Stock in lieu of 65% or 100% (based&#13;on option elected by each director) of the fee payable to the eligible director for services rendered as a member of the Board&#13;of Directors (&amp;#8220;Board&amp;#8221;). The number of shares issued is determined at 75% of the market value as defined in the plan.&#13;The 2003 Plan, as amended, also provides for the grant of an option to purchase up to 6,000 shares of Common Stock for each outside&#13;director upon initial election to the Board, and the grant of an option to purchase 2,400 shares of Common Stock upon each re-election.&#13;At the Annual Meeting of Stockholders held on July 27, 2017 (&amp;#8220;2017 Annual Meeting&amp;#8221;), the Company&amp;#8217;s stockholders&#13;approved an amendment to the 2003 Plan which authorized the issuance of an additional 300,000 shares of the Company&amp;#8217;s Common&#13;Stock under the plan. After the approval of the amendment, the number of shares of the Company&amp;#8217;s Common Stock authorized&#13;under the 2003 Plan was 1,100,000. At December 31, 2017, the 2003 Plan had available for issuance approximately 391,215 shares.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On April 28, 2010, the Company adopted the&#13;2010 Stock Option Plan (&amp;#8220;2010 Plan&amp;#8221;), which was approved by our stockholders at the Company&amp;#8217;s Annual Meeting&#13;of Stockholders on September 29, 2010. The 2010 Plan authorized an aggregate grant of 200,000 Non-Qualified Stock Options (&amp;#8220;NQSOs&amp;#8221;)&#13;and Incentive Stock Options (&amp;#8220;ISOs&amp;#8221;) to officers and employees of the Company for the purchase of up to 200,000 shares&#13;of the Company&amp;#8217;s Common Stock. The term of each stock option granted is to be fixed by the Compensation and Stock Option&#13;Committee (the &amp;#8220;Compensation Committee&amp;#8221;), but no stock option is exercisable more than ten years after the grant date,&#13;or in the case of an incentive stock option granted to a 10% stockholder, five years after the grant date. The exercise price of&#13;any ISO granted under the 2010 Plan to an individual who is not a 10% stockholder at the time of the grant is not to be less than&#13;the fair market value of the shares at the time of the grant, and the exercise price of any incentive stock option granted to a&#13;10% stockholder is not to be less than 110% of the fair market value at the time of grant. The exercise price of any NQSOs granted&#13;under the plan is not to be less than the fair market value of the shares at the time of grant. As discussed below, as the result&#13;of the approval of the 2017 Stock Option Plan (&amp;#8220;2017 Plan&amp;#8221;) at the Company&amp;#8217;s 2017 Annual Meeting, no further&#13;options remain available for issuance under the 2010 Plan immediately upon the approval of the 2017 Plan; however, the 2010 Plan&#13;remains in full force and effect with respect to the outstanding options issued and unexercised at the date of the approval of&#13;the 2017 Plan which consisted of an option for the purchase of up to 10,000 shares of our common stock with expiration date of&#13;July 10, 2020 and an option for the purchase of up to 50,000 shares of the Company&amp;#8217;s Common Stock with expiration date of&#13;May 15, 2022.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company adopted the 2017 Plan, which was&#13;approved by the Company&amp;#8217;s stockholders at the Company&amp;#8217;s 2017 Annual Meeting. The 2017 Plan authorizes the grant of&#13;options to officers and employees of the Company, including any employee who is also a member of the Board, as well as to consultants&#13;of the Company. The 2017 Plan authorizes an aggregate grant of 540,000 NQSOs and ISOs, which includes a rollover of 140,000 shares&#13;remaining available for issuance under the 2010 Plan as discussed above. Consultants of the Company can only be granted NQSOs.&#13;The term of each stock option granted under the 2017 Plan shall be fixed by the Compensation Committee, but no stock options will&#13;be exercisable more than ten years after the grant date, or in the case of an ISO granted to a 10% stockholder, five years after&#13;the grant date. The exercise price of any ISO granted under the 2017 Plan to an individual who is not a 10% stockholder at the&#13;time of the grant shall not be less than the fair market value of the shares at the time of the grant, and the exercise price of&#13;any incentive stock option granted to a 10% stockholder shall not be less than 110% of the fair market value at the time of grant.&#13;The exercise price of any NQSOs granted under the plan shall not be less than the fair market value of the shares at the time of&#13;grant.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Stock Options to Employees and Outside Director&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On January 13, 2017, the Company granted 6,000&#13;NQSOs from the Company&amp;#8217;s 2003 Plan to a new director elected by the Company&amp;#8217;s Board to fill the vacancy left by Jack&#13;Lahav who retired from the Board in October 2016. The options granted were for a contractual term of ten years with a vesting period&#13;of six months. The exercise price of the NQSO was $3.79 per share, which was equal to our closing stock price the day preceding&#13;the grant date, pursuant to the 2003 Plan.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 27, 2017, the Company granted 12,000&#13;NQSOs from the Company&amp;#8217;s 2003 Plan to five of the six re-elected directors at the 2017 Annual Meeting. Dr. Louis F. Centofanti,&#13;who is a member of the Board, is not eligible to receive options under the 2003 Plan since he is also an employee of the Company,&#13;pursuant to the 2003 Plan. The NQSOs granted to the five directors were for a contractual term of ten years with a vesting period&#13;of six months. The exercise price of the NQSO was $3.55 per share, which was equal to our closing stock price the day preceding&#13;the grant date, pursuant to the 2003 Plan.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 27, 2017, the Company granted ISOs&#13;from the 2017 Plan (following the approval of the 2017 Plan as discussed above) to the named executive officers as follows: ISOs&#13;to exercise 50,000 shares to the Chief Executive Officer (&amp;#8220;CEO&amp;#8221;) (Dr. Louis Centofanti); ISOs to exercise 100,000 shares&#13;to the Executive Vice President (&amp;#8220;EVP&amp;#8221;)/Chief Operating Officer (&amp;#8220;COO&amp;#8221;) (Mark Duff); and ISOs to exercise&#13;50,000 shares to the Chief Financial Officer (&amp;#8220;CFO&amp;#8221;) (Ben Naccarato). Effective September 8, 2017, Mark Duff succeeded&#13;Dr. Louis Centofanti as the CEO with Dr. Louis Centofanti serving as EVP of Strategic Initiatives and continuing to serve as a&#13;member of the Board (see &amp;#8220;Note 15 &amp;#8211; Related Party Transaction for further detail of this transition&amp;#8221;). The share&#13;covered by each ISO granted has a contractual term of six years with one-fifth yearly vesting over a five year period. The exercise&#13;price of each share covered by the ISO was $3.65 per share, which was equal to the fair market value of the Company&amp;#8217;s Common&#13;Stock on the date of grant. At December 31, 2017, the 2017 Plan had an additional 130,000 shares of the Company&amp;#8217;s Common&#13;Stock available for the granting of additional options.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On October 19, 2017, the Company granted an&#13;aggregate of 110,000 ISOs from the 2017 Plan to certain employees. The ISOs granted were for a contractual term of six years with&#13;one-fifth yearly vesting over a five year period. The exercise price of the ISO was $3.60 per share, which was equal to the fair&#13;market value of the Company&amp;#8217;s common stock on the date of grant.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On May 15, 2016, the Company granted 50,000&#13;ISOs from the Company&amp;#8217;s 2010 Plan to Mark Duff. The ISOs granted were for a contractual term of six years with one-third&#13;yearly vesting over a three year period. The exercise price of the ISO was $3.97 per share, which was equal to the fair market&#13;value of the Company&amp;#8217;s Common Stock on the date of grant.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 28, 2016, the Company granted an aggregate&#13;of 12,000 NQSOs from the 2003 Plan to five of the seven re-elected directors at our Annual Meeting of Stockholders held on July&#13;28, 2016. Two of the directors were not eligible to receive options under the 2003 Stock Plan as they were employees of the Company&#13;or its subsidiaries. The NQSOs granted were for a contractual term of ten years with a vesting period of six months. The exercise&#13;price of the NQSOs was $4.60 per share, which was equal to the Company&amp;#8217;s closing stock price the day preceding the grant&#13;date, pursuant to the 2003 Plan.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;No employees or directors exercised options&#13;during 2017 and 2016.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates the fair value of stock&#13;options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the&#13;exercise price of the award, the expected term, the expected volatility of the Company&amp;#8217;s stock over the option&amp;#8217;s expected&#13;term, the risk-free interest rate over the option&amp;#8217;s expected term, and the expected annual dividend yield. The fair value&#13;of the options granted during 2017 and 2016 and the related assumptions used in the Black-Scholes option model used to value the&#13;options granted were as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

As a member of the Board, each director elects to receive either 65% or 100% of the director&amp;#8217;s fee in shares&#13;of our Common Stock. The number of shares received is calculated based on 75% of the fair market value of our Common Stock determined&#13;on the business day immediately preceding the date that the quarterly fee is due. The balance of each director&amp;#8217;s fee, if&#13;any, is payable in cash. The Company recorded approximately $234,000 and $233,000 in compensation expense (included in SG&amp;#38;A)&#13;for the twelve months ended December 31, 2017 and 2016, respectively, for the portion of director fees earned in the Company&amp;#8217;s&#13;Common Stock.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Preferred Share Rights Plan&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In May 2008, the Company adopted a preferred&#13;share rights plan (the &amp;#8220;Rights Plan&amp;#8221;), designed to ensure that all of our stockholders receive fair and equal treatment&#13;in the event of a proposed takeover or abusive tender offer.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In general, under the terms of the Rights Plan,&#13;subject to certain limited exceptions, if a person or group acquires 20% or more of our Common Stock or a tender offer or exchange&#13;offer for 20% or more of our Common Stock is announced or commenced, our other stockholders may receive upon exercise of the rights&#13;(the &amp;#8220;Rights&amp;#8221;) issued under the Rights Plan the number of shares of our Common Stock or of one-one hundredths of a&#13;share of our Series A Junior Participating Preferred Stock, par value $.001 per share, having a value equal to two times the purchase&#13;price of the Right. In addition, if the Company is acquired in a merger or other business combination transaction in which we are&#13;not the survivor or more than 50% of our assets or earning power is sold or transferred, then each holder of a Right (other than&#13;the acquirer) will thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal&#13;to two times the purchase price of the Right. The initial purchase price of each Right was $13.00, subject to adjustment as defined&#13;in the plan.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Rights will cause substantial dilution&#13;to a person or group that attempts to acquire us on terms not approved by our board of directors. The Rights may be redeemed by&#13;us at $0.001 per Right at any time before any person or group acquires 20% or more of our outstanding Common Stock. The Rights&#13;Plan terminates on May 2, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Warrants and Common Stock Issuance for Debt&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As December 31, 2017, the Company has no Warrant&#13;outstanding.

The Company divested PFD in 2008; however, the environmental&#13;liability of PFD was retained by the Company upon the divestiture of PFD. These remediation projects principally entail the removal/remediation&#13;of contaminated soil and, in most cases, the remediation of surrounding ground water. The remediation activities are closely reviewed&#13;and monitored by the applicable state regulators.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;At December 31, 2017, we had total accrued&#13;environmental remediation liabilities of $871,000, of which $632,000 are recorded as a current liability, a decrease of $54,000&#13;from the December 31, 2016 balance of $925,000. The net decrease of $54,000 represents payments on remediation projects at PFSG&#13;and PFD totaling approximately of $79,000 and an increase to the reserve of approximately $25,000 at PFD due to reassessment of&#13;the remediation reserve.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif;

The Amended Loan Agreement has been amended from time to time since&#13;the execution of the Amended Loan Agreement. The Amended Loan Agreement, as subsequently amended (&amp;#8220;Revised Loan Agreement&amp;#8221;),&#13;provides the Company with the following credit facility with a maturity date of March 24, 2021: (a) up to $12,000,000 revolving&#13;credit (&amp;#8220;revolving credit&amp;#8221;) and (b) a term loan (&amp;#8220;term loan&amp;#8221;) of approximately $6,100,000, which requires&#13;monthly installments of approximately $101,600 (based on a seven-year amortization). The maximum that we can borrow under the revolving&#13;credit is based on a percentage of eligible receivables (as defined) at any one time reduced by outstanding standby letters of&#13;credit and borrowing reductions that our lender may impose from time to time.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under the Revised Loan Agreement, we have the&#13;option of paying an annual rate of interest due on the revolving credit at prime plus 2% or London Inter Bank Offer Rate (&amp;#8220;LIBOR&amp;#8221;)&#13;plus 3% and the term loan at prime plus 2.5% or LIBOR plus 3.5%.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Pursuant to the Revised Loan Agreement, the&#13;Company may terminate the Revised Loan Agreement, upon 90 days&amp;#8217; prior written notice upon payment in full of its obligations&#13;under the Revised Loan Agreement. The Company agreed to pay PNC 1.0% of the total financing in the event the Company had paid off&#13;its obligations on or before March 23, 2017, .50% of the total financing if the Company pays off its obligations after March 23,&#13;2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23,&#13;2018 but prior to or on March 23, 2019.

The $2,000,000 in borrowing availability reduction&#13;included a $750,000 additional reduction imposed by the Company&amp;#8217;s lender upon the receipt by the Company in May 2017 of $5,941,000&#13;in finite risk funds in connection with the cancellation the closure policy for the Company&amp;#8217;s PFNWR subsidiary (see &amp;#8220;Note&#13;13 &amp;#8211; Commitments and Contingencies &amp;#8211; Insurance&amp;#8221; for further discussion of the closure policy). Our borrowing&#13;availability under our revolving credit was also reduced by outstanding standby letters of credit totaling approximately $2,675,000.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.25in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In connection with one of the amendments that&#13;the Company entered into with PNC during 2016 extending the maturity date of the credit facility, the Company recorded approximately&#13;$68,000 in loss on extinguishment of debt in accordance with ASC 470-50, &amp;#8220;Debt &amp;#8211; Modifications and Extinguishments,&amp;#8221;&#13;which was included in interest expense in the accompanying Consolidated Statements of Operations for fiscal year 2016.

As consideration for the&#13;Company receiving the loan, the Company issued to each Lender a Warrant to purchase up to 35,000 shares of the Company&amp;#8217;s&#13;Common Stock at an exercise price of $2.23 per share. On August 2, 2016, each Lender exercised his Warrant for the purchase of&#13;35,000 shares of our Common Stock, resulting in total proceeds paid to the Company of approximately $156,000. As further consideration&#13;for the loan, the Company had also issued to each Lender 45,000 shares of the Company&amp;#8217;s Common Stock. The fair value of the&#13;Warrants and Common Stock and the related closing fees incurred from this transaction were recorded as debt discount, which has&#13;been fully amortized using the effective interest method over the term of the loan as interest expense &amp;#8211; financing fees.&#13;The loan was repaid in full by the Company in August 2016.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The following table details the amount of the&#13;maturities of long-term debt maturing in future years at December 31, 2017 (net of debt issuance costs of $115,000).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 10pt"&gt;Year ending December 31:&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="padding-right: 10pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: white"&gt;&#13;    &lt;td style="width: 70%"&gt;&lt;font style="font-size: 10pt"&gt;(In thousands)&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 2%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 26%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;2018&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 9pt"&gt;$&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 9pt"&gt;1,184&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: white"&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;2019&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;1,184&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;2020&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;1,184&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: white"&gt;&#13;    &lt;td style="padding-bottom: 1.5pt; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;2021&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 1.5pt solid"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 1.5pt solid; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;295&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td style="padding-right: 30pt; padding-bottom: 2.5pt; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;Total&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 2.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 2.25pt double"&gt;&lt;font style="font-size: 9pt"&gt;$&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 2.25pt double; text-align: right"&gt;&lt;font style="font-size: 9pt"&gt;3,847&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 2.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&#13;&#13;&lt;p style="margin: 0pt"&gt;&lt;/p&gt;</us-gaap:LongTermDebtTextBlock>

margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On December 22, 2017, the Tax Cuts and Jobs&#13;Act of 2017 (the &amp;#8220;Tax Act&amp;#8221;) was signed into law making significant changes to the Internal Revenue Code. Changes include,&#13;but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017,&#13;the transition of U.S international taxation from a worldwide tax system to a territorial system, the elimination of alternative&#13;minimum tax (&amp;#8220;AMT&amp;#8221;) for corporations and a one-time transition tax on the mandatory deemed repatriation of foreign&#13;earnings. As of December 31, 2017, the Company has estimated its provision for income taxes in accordance with the Tax Act and&#13;guidance available resulting in the recognition of approximately $1,695,000 of income tax benefit in the fourth quarter of 2017,&#13;the period in which the legislation was enacted. The tax benefit of $1,695,000 consists of $916,000 related to the re-measurement&#13;of deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future and $779,000 related&#13;to the reversal of valuation allowance and refunding of AMT credit carryforwards.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;While the Tax Act provides for a territorial&#13;tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (&amp;#8220;GILTI&amp;#8221;)&#13;provisions and the base-erosion and anti-abuse tax (&amp;#8220;BEAT&amp;#8221;) provisions.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The GILTI provisions require the Company to&#13;include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary&amp;#8217;s&#13;tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not&#13;provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The BEAT provisions in the Tax Act eliminates&#13;the deduction of certain base-erosion payments made to related foreign corporations, and imposes a minimum tax if greater than&#13;regular tax. The Company does not expect it will be subject to this tax and therefore has not included any tax impacts of BEAT&#13;in its consolidated financial statements for the year ended December 31, 2017.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Tax Act imposes a one-time transition tax&#13;on previously untaxed earnings and profits of foreign subsidiaries. As of December 31, 2017, the Company has current and accumulated&#13;deficits in earnings and profits for all of its foreign subsidiaries. As such, the Company does not expect any exposure to the&#13;one-time transition tax.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The changes to existing U.S. tax laws as a&#13;result of the Tax Act, which the Company believes have the most significant impact on the Company&amp;#8217;s federal income taxes&#13;are as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Reduction of the U.S. Corporate Income Tax&#13;Rate&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company measures deferred tax assets and&#13;liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered&#13;or paid. Accordingly, the Company&amp;#8217;s deferred tax assets and liabilities were re-measured to reflect the reduction in the&#13;U.S. corporate income tax rate from 34% to 21%, resulting in a deferred tax benefit of $916,000 for the year ended December 31,&#13;2017 and a corresponding $916,000 decrease in net deferred tax liabilities as of December 31, 2017. This benefit is attributable&#13;to the Company being in a net deferred tax liability position at the time of re-measurement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Repeal of Alternative Minimum Tax and Refund&#13;of existing AMT Credits&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Tax Act fully repeals the corporate alternative&#13;minimum tax beginning in 2018. Additionally, any AMT credits generated in prior years will be refundable between 2018 and 2021.&#13;The Company had AMT credits in the amount of $779,000 that it was carrying with a full valuation allowance. As a result of the&#13;Tax Act, the valuation allowance against these credits is reversed and the credits are reclassified from a deferred tax asset to&#13;current and long-term tax receivables.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Master Closure Policy, as amended, provides&#13;for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual inflation and other performance&#13;and surety bond requirements. All of the required payments for this Master Closure Policy, as amended, were made by 2012. At December&#13;31, 2017, our financial assurance coverage amount under this Master Closure Policy totaled approximately $29,473,000, which included&#13;a reduction in financial assurance requirement of approximately $9,711,000 for our DSSI subsidiary made during the fourth quarter&#13;of 2016 resulting from a recalculation the state mandated closure requirement. The Company has recorded $15,676,000 and $15,546,000&#13;in sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets at December 31,&#13;2017 and 2016, respectively, which includes interest earned of $1,205,000 and $1,075,000 on the sinking fund as of December 31,&#13;2017 and 2016, respectively. Interest income for the years ended 2017 and 2016 was approximately $130,000 and $86,000, respectively.&#13;If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the sinking fund account balance in return&#13;for complete release of liability from both us and any applicable regulatory agency using this policy as an instrument to comply&#13;with financial assurance requirements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also had a finite risk insurance&#13;policy dated August 2007 for our PFNWR facility with AIG (&amp;#8220;PFNWR policy&amp;#8221;) which provided financial assurance to the&#13;State of Washington in the event of closure of the PFNWR facility. The Company had recorded $5,941,000 in finite risk sinking funds&#13;at December 31, 2016 in other long term assets on the accompanying Consolidated Balance Sheets which included interest earned of&#13;$241,000 on the sinking fund. In April 2017, the Company received final releases from state and federal regulators for the PFNWR&#13;policy which enabled the Company to cancel the PFNWR policy resulting in the release of approximately $5,951,000 on May 1, 2017&#13;in finite sinking funds previously held by AIG as collateral for the PFNWR policy. The Company used the released finite sinking&#13;funds to pay off our revolving credit with the remaining funds used for general working capital needs.

The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a&#13;valuation allowance that reflects management&amp;#8217;s best estimate of the amounts that will not be collected. The Company regularly&#13;reviews all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit&#13;worthiness, estimates the portion, if any, of the balance that will not be collected. This analysis excludes government related&#13;receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible&#13;are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging&#13;category, based on historical experience that allows us to calculate the total allowance required. Once the Company has exhausted&#13;all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment,&#13;collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves&#13;approvals from senior management based on required approval thresholds.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif;

Within our Treatment Segment, the facilities experience delays in processing invoices due to the complexity&#13;of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones&#13;and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially&#13;from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical&#13;testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks relating&#13;to these delays usually take several months to complete. As the Company now has historical data to review the timing of these delays,&#13;the Company realizes that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection&#13;of some of these receivables greater than twelve months. However, our historical experience suggests that a significant portion&#13;of unbilled receivables are ultimately collectible with minimal concession on our part. The Company, therefore, segregates the&#13;unbilled receivables between current and long-term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Unbilled receivables within our Services&#13;Segment can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope,&#13;schedule, and cost to provide an objective measure of project progress) but invoice milestones have not yet been met and/or (2)&#13;contract claims and pending change orders, including Requests for Equitable Adjustments (&amp;#8220;REAs&amp;#8221;) when work has been&#13;performed and collection of revenue is reasonably assured.&lt;/p&gt;</us-gaap:TradeAndOtherAccountsReceivableUnbilledReceivablesPolicy>

Generally, asset lives range from&#13;ten to forty years for buildings (including improvements and asset retirement costs) and three to seven years for office furniture&#13;and equipment, vehicles, and decontamination and processing equipment. Leasehold improvements are capitalized and amortized over&#13;the lesser of the term of the lease or the life of the asset. Maintenance and repairs are charged directly to expense as incurred.&#13;The cost and accumulated depreciation of assets sold or retired are removed from the respective accounts, and any gain or loss&#13;from sale or retirement is recognized in the accompanying Consolidated Statements of Operations. Renewals and improvements, which&#13;extend the useful lives of the assets, are capitalized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In accordance with Accounting Standards&#13;Codification (&amp;#8220;ASC&amp;#8221;) 360, &amp;#8220;Property, Plant, and Equipment&amp;#8221;, long-lived assets, such as property, plant&#13;and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an&#13;asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of&#13;an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset&#13;exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset&#13;exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the&#13;lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal&#13;group classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.&#13;See &amp;#8220;Note 3 &amp;#8211; M&amp;#38;EC Facility&amp;#8221; for impairment charges incurred on tangible assets resulting from the pending&#13;closure of the M&amp;#38;EC facility.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our depreciation expense totaled approximately&#13;$3,429,000 and $3,717,000 in 2017 and 2016, respectively.&lt;/p&gt;</us-gaap:PropertyPlantAndEquipmentPolicyTextBlock>

ASC 410, &amp;#8220;Asset&#13;Retirement and Environmental Obligations&amp;#8221; requires that the discounted fair value of a liability for an ARO be recognized&#13;in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition&#13;of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities,&#13;timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate&#13;to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then&#13;discounted back, using a credit adjusted risk free rate, to the present value. ARO&amp;#8217;s are included within buildings as part&#13;of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial&#13;measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time&#13;and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability&#13;due to passage of time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting&#13;from changes or expansion at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation&#13;expense, in accordance with the Company&amp;#8217;s depreciation policy.&lt;/p&gt;</us-gaap:AssetRetirementObligationsPolicy>

Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable&#13;income in the years in which those temporary differences are expected to be recovered or settled.

The Treatment Segment has waste tracking capabilities, which it&#13;continues to enhance, to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized&#13;as each of the following three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However,&#13;based on the processing of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as&#13;sometimes they are completed concurrently. As major processing phases are completed and the costs are incurred, the Treatment Segment&#13;recognizes the corresponding percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences&#13;delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference&#13;between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The&#13;timing differences occur for several reasons, partially from delays in the final processing of all wastes associated with certain&#13;work orders and partially from delays for analytical testing that is required after the waste is processed but prior to our release&#13;of the waste for disposal. As the waste moves through these processing phases and revenues are recognized, the correlating costs&#13;are expensed as incurred. Although the Treatment Segment uses its best estimates and all available information to accurately determine&#13;these disposal expenses, the risk does exist that these estimates could prove to be inadequate in the event the waste requires&#13;retreatment. Furthermore, should the waste be returned to the customer, the related receivables could be uncollectible; however,&#13;historical experience has not indicated this to be a material uncertainty.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Services Segment revenues&lt;/i&gt;. Revenue&#13;includes services performed under fixed price, time and material, and cost-reimbursement contracts. Revenues and costs associated&#13;with fixed price contracts are recognized using the percentage of completion (efforts expended) method. The Services Segment estimates&#13;its percentage of completion based on attainment of project milestones. Revenues and costs associated with time and material contracts&#13;are recognized as revenue when earned and costs are incurred.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under cost reimbursement contracts,&#13;the Services Segment is reimbursed for costs incurred plus a certain percentage markup for indirect costs, in accordance with contract&#13;provisions. Costs incurred in excess of contract funding may be renegotiated for reimbursement. The Services Segment also earns&#13;a fee based on the approved costs to complete the contract. The Services Segment recognizes this fee using the proportion of costs&#13;incurred to total estimated contract costs.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Contract costs include all direct labor,&#13;material and other non-labor costs and those indirect costs related to contract support, such as depreciation, fringe benefits,&#13;overhead labor, supplies, tools, repairs and equipment rental.

Transition guidance included in certain issued but not yet adopted ASUs were also updated to&#13;reflect this update. This update is effective immediately.

Topic 606 provides&#13;a single, comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process&#13;is utilized in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that&#13;reflects the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure&#13;surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant&#13;judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective&#13;for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The&#13;new standard permits two implementation approaches: the full retrospective method, in which case the standard would be applied&#13;to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest&#13;period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized&#13;at the date of initial application. The Company has completed the evaluation of customer contracts and continues to identify and&#13;implement appropriate changes to our business policies, processes, systems and controls to support the adoption, recognition and&#13;disclosures under the new standard. The Company will adopt the new revenue standard in the first quarter of 2018 applying the modified&#13;retrospective method. Based on our evaluation, we do not believe that the adoption of ASU 2014-09 will result in a significant&#13;change in accounting principles applied to the Company&amp;#8217;s financial position, results of operations or cash flows. We believe&#13;that revenue will continue to be generally recognized consistent with our current revenue recognition model. The potential future&#13;impacts would be limited to the capitalization of direct and incremental contract acquisition costs, which have not historically&#13;been material. The Company will continue to monitor the materiality of these contract acquisition costs on an ongoing basis to&#13;determine if these costs become material and should be capitalized. In accordance with the new standard, the Company will expand&#13;revenue recognition disclosures beginning in the first quarter of 2018 to address the new qualitative and quantitative requirements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In February 2016, the FASB issued ASU&#13;No. 2016-02, &amp;#8220;Leases (Topic 842).&amp;#8221; Under ASU 2016-02, an entity will be required to recognize right-of-use assets and&#13;lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting&#13;guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and&#13;quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and&#13;uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning&#13;after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption,&#13;with early adoption permitted. This ASU is effective January 1, 2019 for the Company.

Subsequently,&#13;in November 2016, the FASB issued ASU 2016-18, &amp;#8220;Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the&#13;FASB Emerging Issues Task Force,&amp;#8221; which clarifies the guidance on the cash flow classification and presentation of changes&#13;in restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash&#13;equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total&#13;amounts shown on the statement of cash flow. ASU 2016-15 and ASU 2016-18 are effective for annual reporting periods, and interim&#13;periods therein, beginning after December 15, 2017 and are effective January 1, 2018 for the Company.

Down round features are features of certain equity-linked instruments (or embedded features) that result&#13;in the strike price being reduced on the basis of the pricing of future equity offerings. When determining whether certain financial&#13;instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification&#13;when assessing whether the instrument is indexed to an entity&amp;#8217;s own stock. Part II of this update addresses the difficulty&#13;of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB&#13;Accounting Standards Codification and does not have an accounting effect. This ASU is effective for fiscal years, and interim periods&#13;within those years, beginning after December 15, 2018. Early adoption is permitted.

The liquidation preference is the difference between the preference in liquidation and the par or stated values of the share. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.</p></div>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s cash flow requirements
for 2018 and into the first quarter of 2019 will consist primarily of general working capital needs, scheduled principal payments
on our debt obligations, remediation projects, planned capital expenditures and closure spending requirements in connection with
the closure of our M&#38;EC facility (&#8220;M&#38;EC closure&#8221;) (see &#8220;Note 3 &#8211; M&#38;EC facility&#8221; for further
discussion of the pending M&#38;EC closure) which we plan to fund from operations and our credit facility availability. The Company
continues to explore all sources of increasing revenue. The Company is continually reviewing operating costs and is committed to
further reducing operating costs to bring them in line with revenue levels, when necessary.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously disclosed, during the latter
part of 2016, the Company&#8217;s Medical Segment reduced its R&#38;D activities substantially due to the need for capital to
fund such activities. The Company anticipates that the Medical Segment will not resume full R&#38;D activities until the necessary
capital is obtained through its own credit facility or additional equity raise. Our Medical Segment continues to seek various
sources in order to raise this funding. If the Medical Segment is unable to raise the necessary capital, the Medical Segment could
be required to further reduce, delay or eliminate its R&#38;D program.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">When the Company prepares financial statements
in conformity with accounting standards generally accepted in the United States of America (&#8220;US GAAP&#8221;), the Company
makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets
and liabilities at the date of the financial statements, as well as, the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates. See Notes 8, 11, 12 and 13 for estimates of discontinued operations and
environmental liabilities, closure costs, income taxes and contingencies for details on significant estimates.</p>

At December 31, 2016, the Company had cash on hand of approximately $163,000, which included account balances for our foreign subsidiaries

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accounts receivable are customer obligations
due under normal trade terms requiring payment within 30 or 60 days from the invoice date based on the customer type (government,
broker, or commercial). The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a
valuation allowance that reflects management&#8217;s best estimate of the amounts that will not be collected. The Company regularly
reviews all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit
worthiness, estimates the portion, if any, of the balance that will not be collected. This analysis excludes government related
receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible
are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging
category, based on historical experience that allows us to calculate the total allowance required. Once the Company has exhausted
all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment,
collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves
approvals from senior management based on required approval thresholds.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Unbilled receivables are generated by differences
between invoicing timing and our proportional performance based methodology used for revenue recognition purposes. As major processing
and contract completion phases are completed and the costs are incurred, the Company recognizes the corresponding percentage of
revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to the complexity of the documentation
that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon
invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially from delays
in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that
is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks relating to these
delays usually take several months to complete. As the Company now has historical data to review the timing of these delays, the
Company realizes that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection
of some of these receivables greater than twelve months. However, our historical experience suggests that a significant portion
of unbilled receivables are ultimately collectible with minimal concession on our part. The Company, therefore, segregates the
unbilled receivables between current and long-term.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Unbilled receivables within our Services Segment
can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope, schedule,
and cost to provide an objective measure of project progress) but invoice milestones have not yet been met and/or (2) contract
claims and pending change orders, including Requests for Equitable Adjustments (&#8220;REAs&#8221;) when work has been performed
and collection of revenue is reasonably assured.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Inventories consist of treatment chemicals,
saleable used oils, and certain supplies. Additionally, the Company has replacement parts in inventory, which are deemed critical
to the operating equipment and may also have extended lead times should the part fail and need to be replaced. Inventories are
valued at the lower of cost or market with cost determined by the first-in, first-out method.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Property and equipment expenditures are capitalized
and depreciated using the straight-line method over the estimated useful lives of the assets for financial statement purposes,
while accelerated depreciation methods are principally used for income tax purposes. Generally, asset lives range from ten to forty
years for buildings (including improvements and asset retirement costs) and three to seven years for office furniture and equipment,
vehicles, and decontamination and processing equipment. Leasehold improvements are capitalized and amortized over the lesser of
the term of the lease or the life of the asset. Maintenance and repairs are charged directly to expense as incurred. The cost and
accumulated depreciation of assets sold or retired are removed from the respective accounts, and any gain or loss from sale or
retirement is recognized in the accompanying Consolidated Statements of Operations. Renewals and improvements, which extend the
useful lives of the assets, are capitalized.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In accordance with Accounting Standards Codification
(&#8220;ASC&#8221;) 360, &#8220;Property, Plant, and Equipment&#8221;, long-lived assets, such as property, plant and equipment,
are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated
undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated
future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair
value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying
amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified
as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet. See &#8220;Note
3 &#8211; M&#38;EC Facility&#8221; for impairment charges incurred on tangible assets resulting from the pending closure of the
M&#38;EC facility.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our depreciation expense totaled approximately
$3,429,000 and $3,717,000 in 2017 and 2016, respectively.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Intangible assets consist primarily of the
recognized value of the permits required to operate our business. We continually monitor the propriety of the carrying amount of
our permits to determine whether current events and circumstances warrant adjustments to the carrying value.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Indefinite-lived intangible assets are not
amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate
that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, we perform a quantitative
test to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over
its fair value. Significant judgments are inherent in these analyses and include assumptions for, among other factors, forecasted
revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate
long term discount rates.</p>

related to our Treatment reporting unit as of October 1, 2017 resulted in no impairment charges for the year ended December 31,
2017. In 2016, the Company fully impaired the permit value of our M&#38;EC subsidiary resulting from the pending closure of the
facility (see &#8220;Note 3 &#8211; M&#38;EC Facility&#8221; for further information of this impairment). The Company performed
impairment testing of its remaining permits related to the Treatment reporting unit as of October 1, 2016 and determined there
was no further impairment.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Intangible assets that have definite useful
lives are amortized using the straight-line method over the estimated useful lives (with the exception of customer relationships
which are amortized using an accelerated method) and are excluded from our annual intangible asset valuation review as of October
1. The Company has one definite-lived permit which was excluded from our annual impairment review as noted above. Definite-lived

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accrued closure costs represent our estimated
environmental liability to clean up our facilities, as required by our permits, in the event of closure. ASC 410, &#8220;Asset
Retirement and Environmental Obligations&#8221; requires that the discounted fair value of a liability for an ARO be recognized
in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition
of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities,
timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate
to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then
discounted back, using a credit adjusted risk free rate, to the present value. ARO&#8217;s are included within buildings as part
of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial
measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time
and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability
due to passage of time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting
from changes or expansion at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation
expense, in accordance with the Company&#8217;s depreciation policy.</p>

payable and deferred taxes that relate to the temporary differences between financial reporting carrying values and tax bases of
assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable

be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred income tax assets will

to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized.</p>

to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out disclosure requirements to
enhance transparency of an entity&#8217;s tax reserves. The Company recognizes accrued interest and income tax penalties related
to unrecognized tax benefits as a component of income tax expense.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><i>Treatment Segment revenues.</i> The processing
of mixed waste is complex and may take several months or more to complete; as such, the Treatment Segment recognizes revenues using
a proportional performance based methodology with its measure of progress towards completion determined based on output measures
consisting of milestones achieved and completed. The Treatment Segment has waste tracking capabilities, which it continues to enhance,
to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized as each of the following
three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However, based on the processing
of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as sometimes they are completed
concurrently. As major processing phases are completed and the costs are incurred, the Treatment Segment recognizes the corresponding
percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences delays in processing invoices
due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue
recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for
several reasons, partially from delays in the final processing of all wastes associated with certain work orders and partially
from delays for analytical testing that is required after the waste is processed but prior to our release of the waste for disposal.
As the waste moves through these processing phases and revenues are recognized, the correlating costs are expensed as incurred.
Although the Treatment Segment uses its best estimates and all available information to accurately determine these disposal expenses,
the risk does exist that these estimates could prove to be inadequate in the event the waste requires retreatment. Furthermore,
should the waste be returned to the customer, the related receivables could be uncollectible; however, historical experience has
not indicated this to be a material uncertainty.</p>

The measurement date for the fair value of the stock-based payment transaction is determined at the earlier of performance commitment
date or performance completion date. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based
awards which requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise
price of the award, the expected term, the expected volatility of our stock over the stock-based award&#8217;s expected term, the
risk-free interest rate over the award&#8217;s expected term, and the expected annual dividend yield. The Company accounts for

&#8220;Revenue from Contracts with Customers&#8221; followed by a series of related accounting standard updates (collectively referred
to as &#8220;Topic 606&#8221;), which will supersede nearly all existing revenue recognition guidance. Topic 606 provides a single,
comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process is utilized
in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects
the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure
surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant
judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective
for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The
new standard permits two implementation approaches: the full retrospective method, in which case 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, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized
at the date of initial application. The Company has completed the evaluation of customer contracts and continues to identify and
implement appropriate changes to our business policies, processes, systems and controls to support the adoption, recognition and

that revenue will continue to be generally recognized consistent with our current revenue recognition model. The potential future
impacts would be limited to the capitalization of direct and incremental contract acquisition costs, which have not historically

of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB
Accounting Standards Codification and does not have an accounting effect. This ASU is effective for fiscal years, and interim periods
within those years, beginning after December 15, 2018. Early adoption is permitted. This ASU is effective for the Company January
1, 2019. The Company is currently assessing the impact that this standard will have on its financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In February 2018, FASB issued ASU 2018-02<i>,
&#8220;</i>Income Statement&#8212;Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated
Other Comprehensive Income&#8221;. This ASU allows for the reclassification of certain income tax effects related to the Tax Cuts
and Jobs Act between &#8220;Accumulated other comprehensive income&#8221; and &#8220;Retained earnings.&#8221; This ASU relates
to the requirement that adjustments to deferred tax liabilities and assets related to a change in tax laws or rates to be included
in &#8220;Income from continuing operations&#8221;, even in situations where the related items were originally recognized in &#8220;Other
comprehensive income&#8221; (rather than in &#8220;Income from continuing operations&#8221;). ASU 2018-02 is effective for all
entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption
permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the
effect of the change in the tax laws or rates were recognized. The Company is currently assessing the impact that this standard
will have on its financial statements.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>&#160;</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During the second quarter of 2016, the Company&#8217;s
M&#38;EC subsidiary was notified by the lessor that the lease agreement under which M&#38;EC operates its Oak Ridge, Tennessee
facility would not be renewed at the end of the lease term ending January 21, 2018. In light of this event and our strategic review
of operations within our Treatment Segment, the Company instituted a plan to close its M&#38;EC facility located in Oak Ridge,
Tennessee at the end of the lease term which has been extended to June 30, 2018. Operations at the M&#38;EC facility are limited
during the remaining term of the lease and the facility continues to transition waste shipments and operational capabilities to
our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Simultaneously, the Company
continues with closure and decommissioning activities in accordance with M&#38;EC&#8217;s license and permit requirements. As a
result of the Company&#8217;s decision to close its M&#38;EC facility, the Company&#8217;s financial results have been impacted
by certain non-cash impairment losses, write-offs and accruals as described below for years ended December 31, 2017 and 2016.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company performed a discounted cash flow
analysis prepared at June 30, 2016 for M&#38;EC&#8217;s intangible assets (permits), utilizing our best estimates of projected
future cash flows. Based on this analysis, the Company concluded that impairment existed and subsequently determined that the permit
for our M&#38;EC subsidiary was fully impaired resulting in an intangible impairment loss of approximately $8,288,000.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; color: #252525">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">M&#38;EC is required to complete certain clean-up/maintenance
activities at its facility pursuant to its permit requirements. The extent and cost of these activities are determined by federal/state
mandate requirements. The Company performed an analysis and related estimate of the cost to complete the closure activities in
accordance with its permit requirements during the second quarter of 2016 and based on this analysis, the Company recorded an additional
$1,626,000 in closure liabilities with a corresponding increase to capitalized ARO costs, which were being depreciated over the
remaining term of the lease. The capitalized ARO costs were reported as a component of &#8220;Net Property and equipment&#8221;
in the Consolidated Balance Sheets.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In accordance with ASC 360, &#8220;Property,
Plant, and Equipment,&#8221; the Company performed an updated financial valuation of M&#38;EC&#8217;s long-lived tangible assets
during the second quarter of 2016, inclusive of the capitalized ARO costs, for potential impairment. Based on our analysis using
an undiscounted cash flows approach, the Company concluded that the carrying value of certain tangible assets (property and equipment)
for M&#38;EC was not recoverable and exceeded its fair value. Consequently, the Company recorded $1,816,000 in tangible asset impairment
loss in the second quarter of 2016. The Company also reevaluated the estimated useful lives of the remaining tangible assets and
as a result of this analysis, reduced the current estimated useful lives of these assets ranging from 2 to 28 years at June 30,
2016 to 1.6 years, the remaining term of the lease. Accordingly, the Company was depreciating the carrying value of M&#38;EC&#8217;s
remaining tangible assets of approximately $4,728,000 at June 30, 2016 over a period of approximately 1.6 years, which was to the
original lease expiration date of January 21, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In the second quarter of 2016, the Company
also wrote-off approximately $587,000 in fees previously incurred relating to emission performance testing certification requirement
in order to meet state compliance mandate in connection with certain M&#38;EC equipment which was impaired. Such amount had been
previously included in &#8220;Prepaid and other assets&#8221; on the Consolidated Balance Sheets.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During the third quarter of 2017, the Company
performed an updated financial valuation of M&#38;EC&#8217;s remaining long-lived tangible assets (inclusive of ARO costs) for
further potential impairment. Based on our analysis using an undiscounted cash flow approach, the Company concluded that the carrying
value of the remaining tangible assets for M&#38;EC was not recoverable and exceeded its fair value. Consequently, the Company
fully impaired the remaining tangible assets at M&#38;EC resulting in a tangible asset impairment loss of $672,000. Additionally,
during the third and fourth quarters of 2017, the Company recorded an additional $550,000 and $850,000, respectively, in closure
costs and current closure costs liabilities due to change in estimated closure costs.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During the years ended December 31, 2017 and
2016, M&#38;EC&#8217;s revenues were approximately $6,312,000 and $4,419,000, respectively.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company adopted the 2003 Outside Directors
Stock Plan (the &#8220;2003 Plan&#8221;), which was approved by our stockholders at the Annual Meeting of Stockholders on July
29, 2003. Options granted under the 2003 Plan generally have a vesting period of six months from the date of grant and a term of
10 years, with an exercise price equal to the closing trade price on the date prior to grant date. The 2003 Plan also provides
for the issuance to each outside director a number of shares of the Company&#8217;s Common Stock in lieu of 65% or 100% (based
on option elected by each director) of the fee payable to the eligible director for services rendered as a member of the Board
of Directors (&#8220;Board&#8221;). The number of shares issued is determined at 75% of the market value as defined in the plan.
The 2003 Plan, as amended, also provides for the grant of an option to purchase up to 6,000 shares of Common Stock for each outside
director upon initial election to the Board, and the grant of an option to purchase 2,400 shares of Common Stock upon each re-election.
At the Annual Meeting of Stockholders held on July 27, 2017 (&#8220;2017 Annual Meeting&#8221;), the Company&#8217;s stockholders
approved an amendment to the 2003 Plan which authorized the issuance of an additional 300,000 shares of the Company&#8217;s Common
Stock under the plan. After the approval of the amendment, the number of shares of the Company&#8217;s Common Stock authorized
under the 2003 Plan was 1,100,000. At December 31, 2017, the 2003 Plan had available for issuance approximately 391,215 shares.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On April 28, 2010, the Company adopted the
2010 Stock Option Plan (&#8220;2010 Plan&#8221;), which was approved by our stockholders at the Company&#8217;s Annual Meeting
of Stockholders on September 29, 2010. The 2010 Plan authorized an aggregate grant of 200,000 Non-Qualified Stock Options (&#8220;NQSOs&#8221;)
and Incentive Stock Options (&#8220;ISOs&#8221;) to officers and employees of the Company for the purchase of up to 200,000 shares
of the Company&#8217;s Common Stock. The term of each stock option granted is to be fixed by the Compensation and Stock Option
Committee (the &#8220;Compensation Committee&#8221;), but no stock option is exercisable more than ten years after the grant date,
or in the case of an incentive stock option granted to a 10% stockholder, five years after the grant date. The exercise price of
any ISO granted under the 2010 Plan to an individual who is not a 10% stockholder at the time of the grant is not to be less than
the fair market value of the shares at the time of the grant, and the exercise price of any incentive stock option granted to a
10% stockholder is not to be less than 110% of the fair market value at the time of grant. The exercise price of any NQSOs granted
under the plan is not to be less than the fair market value of the shares at the time of grant. As discussed below, as the result
of the approval of the 2017 Stock Option Plan (&#8220;2017 Plan&#8221;) at the Company&#8217;s 2017 Annual Meeting, no further
options remain available for issuance under the 2010 Plan immediately upon the approval of the 2017 Plan; however, the 2010 Plan
remains in full force and effect with respect to the outstanding options issued and unexercised at the date of the approval of
the 2017 Plan which consisted of an option for the purchase of up to 10,000 shares of our common stock with expiration date of
July 10, 2020 and an option for the purchase of up to 50,000 shares of the Company&#8217;s Common Stock with expiration date of
May 15, 2022.</p>

options to officers and employees of the Company, including any employee who is also a member of the Board, as well as to consultants
of the Company. The 2017 Plan authorizes an aggregate grant of 540,000 NQSOs and ISOs, which includes a rollover of 140,000 shares
remaining available for issuance under the 2010 Plan as discussed above. Consultants of the Company can only be granted NQSOs.
The term of each stock option granted under the 2017 Plan shall be fixed by the Compensation Committee, but no stock options will
be exercisable more than ten years after the grant date, or in the case of an ISO granted to a 10% stockholder, five years after
the grant date. The exercise price of any ISO granted under the 2017 Plan to an individual who is not a 10% stockholder at the

any incentive stock option granted to a 10% stockholder shall not be less than 110% of the fair market value at the time of grant.

pursuant to the 2003 Plan. The NQSOs granted to the five directors were for a contractual term of ten years with a vesting period

price of each share covered by the ISO was $3.65 per share, which was equal to the fair market value of the Company&#8217;s Common

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company issued a total of 61,598 and 55,793
shares of our Common Stock in 2017 and 2016, respectively, under our 2003 Plan to our outside directors as compensation for serving
on our Board. As a member of the Board, each director elects to receive either 65% or 100% of the director&#8217;s fee in shares
of our Common Stock. The number of shares received is calculated based on 75% of the fair market value of our Common Stock determined
on the business day immediately preceding the date that the quarterly fee is due. The balance of each director&#8217;s fee, if
any, is payable in cash. The Company recorded approximately $234,000 and $233,000 in compensation expense (included in SG&#38;A)
for the twelve months ended December 31, 2017 and 2016, respectively, for the portion of director fees earned in the Company&#8217;s
Common Stock.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In May 2008, the Company adopted a preferred
share rights plan (the &#8220;Rights Plan&#8221;), designed to ensure that all of our stockholders receive fair and equal treatment
in the event of a proposed takeover or abusive tender offer.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In general, under the terms of the Rights Plan,
subject to certain limited exceptions, if a person or group acquires 20% or more of our Common Stock or a tender offer or exchange
offer for 20% or more of our Common Stock is announced or commenced, our other stockholders may receive upon exercise of the rights
(the &#8220;Rights&#8221;) issued under the Rights Plan the number of shares of our Common Stock or of one-one hundredths of a
share of our Series A Junior Participating Preferred Stock, par value $.001 per share, having a value equal to two times the purchase
price of the Right. In addition, if the Company is acquired in a merger or other business combination transaction in which we are
not the survivor or more than 50% of our assets or earning power is sold or transferred, then each holder of a Right (other than
the acquirer) will thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal
to two times the purchase price of the Right. The initial purchase price of each Right was $13.00, subject to adjustment as defined
in the plan.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Rights will cause substantial dilution
to a person or group that attempts to acquire us on terms not approved by our board of directors. The Rights may be redeemed by
us at $0.001 per Right at any time before any person or group acquires 20% or more of our outstanding Common Stock. The Rights
Plan terminates on May 2, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As December 31, 2017, the Company has no Warrant
outstanding. On August 2, 2016, the Company issued an aggregate of 70,000 shares of the Company&#8217;s Common Stock resulting
from the exercise of two Warrants, at an exercise price of $2.23 per share, issued to two lenders in connection with a $3,000,000
loan dated August 2, 2013 received by the Company (See Note 9 &#8211; &#8220;Long-Term Debt &#8211; Promissory Note&#8221; for

&#8211; closed location), and PFSG (in closure status) subsidiaries. The Company divested PFD in 2008; however, the environmental
liability of PFD was retained by the Company upon the divestiture of PFD. These remediation projects principally entail the removal/remediation
of contaminated soil and, in most cases, the remediation of surrounding ground water. The remediation activities are closely reviewed
and monitored by the applicable state regulators.</p>

from the December 31, 2016 balance of $925,000. The net decrease of $54,000 represents payments on remediation projects at PFSG
and PFD totaling approximately of $79,000 and an increase to the reserve of approximately $25,000 at PFD due to reassessment of
the remediation reserve.</p>

Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011 (&#8220;Amended Loan Agreement&#8221;), with PNC National
Association (&#8220;PNC&#8221;), acting as agent and lender. The Amended Loan Agreement has been amended from time to time since
the execution of the Amended Loan Agreement. The Amended Loan Agreement, as subsequently amended (&#8220;Revised Loan Agreement&#8221;),
provides the Company with the following credit facility with a maturity date of March 24, 2021: (a) up to $12,000,000 revolving
credit (&#8220;revolving credit&#8221;) and (b) a term loan (&#8220;term loan&#8221;) of approximately $6,100,000, which requires
monthly installments of approximately $101,600 (based on a seven-year amortization). The maximum that we can borrow under the revolving
credit is based on a percentage of eligible receivables (as defined) at any one time reduced by outstanding standby letters of
credit and borrowing reductions that our lender may impose from time to time.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under the Revised Loan Agreement, we have the
option of paying an annual rate of interest due on the revolving credit at prime plus 2% or London Inter Bank Offer Rate (&#8220;LIBOR&#8221;)
plus 3% and the term loan at prime plus 2.5% or LIBOR plus 3.5%.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Pursuant to the Revised Loan Agreement, the
Company may terminate the Revised Loan Agreement, upon 90 days&#8217; prior written notice upon payment in full of its obligations
under the Revised Loan Agreement. The Company agreed to pay PNC 1.0% of the total financing in the event the Company had paid off
its obligations on or before March 23, 2017, .50% of the total financing if the Company pays off its obligations after March 23,
2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23,
2018 but prior to or on March 23, 2019. No early termination fee shall apply if the Company pays off its obligations after March
23, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">At December 31, 2017, the borrowing availability
under our revolving credit was approximately $3,687,000, based on our eligible receivables and includes an indefinite reduction
of borrowing availability of $2,000,000 that the Company&#8217;s lender has imposed. The $2,000,000 in borrowing availability reduction
included a $750,000 additional reduction imposed by the Company&#8217;s lender upon the receipt by the Company in May 2017 of $5,941,000
in finite risk funds in connection with the cancellation the closure policy for the Company&#8217;s PFNWR subsidiary (see &#8220;Note
13 &#8211; Commitments and Contingencies &#8211; Insurance&#8221; for further discussion of the closure policy). Our borrowing
availability under our revolving credit was also reduced by outstanding standby letters of credit totaling approximately $2,675,000.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In connection with one of the amendments that
the Company entered into with PNC during 2016 extending the maturity date of the credit facility, the Company recorded approximately
$68,000 in loss on extinguishment of debt in accordance with ASC 470-50, &#8220;Debt &#8211; Modifications and Extinguishments,&#8221;
which was included in interest expense in the accompanying Consolidated Statements of Operations for fiscal year 2016. Additionally,
the Company paid its lenders closing fees totaling approximately $122,000 in connection with the amendments executed in 2016 which
is being amortized over the remaining term of the loan as interest expense-financing fees.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s credit facility with PNC
contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants,
unless waived by PNC, could result in a default under our credit facility allowing our lender to immediately require the repayment
of all outstanding debt under our credit facility and terminate all commitments to extend further credit. The Company met all of
its quarterly financial covenant requirements in 2017 and expects to meet these financial covenant requirements in 2018 and into
the first quarter of 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company entered into a $3,000,000 loan
dated August 2, 2013 with Robert Ferguson and William Lampson (each known as the &#8220;Lender&#8221;). As consideration for the
Company receiving the loan, the Company issued to each Lender a Warrant to purchase up to 35,000 shares of the Company&#8217;s
Common Stock at an exercise price of $2.23 per share. On August 2, 2016, each Lender exercised his Warrant for the purchase of
35,000 shares of our Common Stock, resulting in total proceeds paid to the Company of approximately $156,000. As further consideration
for the loan, the Company had also issued to each Lender 45,000 shares of the Company&#8217;s Common Stock. The fair value of the
Warrants and Common Stock and the related closing fees incurred from this transaction were recorded as debt discount, which has
been fully amortized using the effective interest method over the term of the loan as interest expense &#8211; financing fees.
The loan was repaid in full by the Company in August 2016.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On December 22, 2017, the Tax Cuts and Jobs
Act of 2017 (the &#8220;Tax Act&#8221;) was signed into law making significant changes to the Internal Revenue Code. Changes include,
but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017,
the transition of U.S international taxation from a worldwide tax system to a territorial system, the elimination of alternative
minimum tax (&#8220;AMT&#8221;) for corporations and a one-time transition tax on the mandatory deemed repatriation of foreign
earnings. As of December 31, 2017, the Company has estimated its provision for income taxes in accordance with the Tax Act and
guidance available resulting in the recognition of approximately $1,695,000 of income tax benefit in the fourth quarter of 2017,
the period in which the legislation was enacted. The tax benefit of $1,695,000 consists of $916,000 related to the re-measurement
of deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future and $779,000 related
to the reversal of valuation allowance and refunding of AMT credit carryforwards.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">While the Tax Act provides for a territorial
tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (&#8220;GILTI&#8221;)
provisions and the base-erosion and anti-abuse tax (&#8220;BEAT&#8221;) provisions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The GILTI provisions require the Company to
include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary&#8217;s
tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not
provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The BEAT provisions in the Tax Act eliminates
the deduction of certain base-erosion payments made to related foreign corporations, and imposes a minimum tax if greater than
regular tax. The Company does not expect it will be subject to this tax and therefore has not included any tax impacts of BEAT
in its consolidated financial statements for the year ended December 31, 2017.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Tax Act imposes a one-time transition tax
on previously untaxed earnings and profits of foreign subsidiaries. As of December 31, 2017, the Company has current and accumulated
deficits in earnings and profits for all of its foreign subsidiaries. As such, the Company does not expect any exposure to the
one-time transition tax.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The changes to existing U.S. tax laws as a
result of the Tax Act, which the Company believes have the most significant impact on the Company&#8217;s federal income taxes
are as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><i>Reduction of the U.S. Corporate Income Tax
Rate</i></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company measures deferred tax assets and
liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered
or paid. Accordingly, the Company&#8217;s deferred tax assets and liabilities were re-measured to reflect the reduction in the
U.S. corporate income tax rate from 34% to 21%, resulting in a deferred tax benefit of $916,000 for the year ended December 31,
2017 and a corresponding $916,000 decrease in net deferred tax liabilities as of December 31, 2017. This benefit is attributable
to the Company being in a net deferred tax liability position at the time of re-measurement.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><i>Repeal of Alternative Minimum Tax and Refund
of existing AMT Credits</i></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Tax Act fully repeals the corporate alternative
minimum tax beginning in 2018. Additionally, any AMT credits generated in prior years will be refundable between 2018 and 2021.
The Company had AMT credits in the amount of $779,000 that it was carrying with a full valuation allowance. As a result of the
Tax Act, the valuation allowance against these credits is reversed and the credits are reclassified from a deferred tax asset to
current and long-term tax receivables.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company had temporary differences and net
operating loss carry forwards from both our continuing and discontinued operations, which gave rise to deferred tax assets and
liabilities at December 31, 2017 and 2016 as follows (in thousands):</p>

of our majority-owned subsidiary, PF Medical, which is not part of our consolidated group for tax purposes. These net operating
losses can be carried forward and applied against future taxable income, if any, and expire in various amounts starting in 2021.
However, as a result of various stock offerings and certain acquisitions, which in the aggregate constitute a change in control,
the use of these NOLs will be limited under the provisions of Section 382 of the Internal Revenue Code of 1986, as amended. Additionally,
NOLs may be further limited under the provisions of Treasury Regulation 1.1502-21 regarding Separate Return Limitation Years.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has a 25-year finite risk
insurance policy entered into in June 2003 (&#8220;Master Closure Policy&#8221;) with AIG, which provides financial assurance to
the applicable states for our permitted facilities in the event of unforeseen closure. The Master Closure Policy, as amended, provides
for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual inflation and other performance
and surety bond requirements. All of the required payments for this Master Closure Policy, as amended, were made by 2012. At December
31, 2017, our financial assurance coverage amount under this Master Closure Policy totaled approximately $29,473,000, which included
a reduction in financial assurance requirement of approximately $9,711,000 for our DSSI subsidiary made during the fourth quarter
of 2016 resulting from a recalculation the state mandated closure requirement. The Company has recorded $15,676,000 and $15,546,000
in sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets at December 31,
2017 and 2016, respectively, which includes interest earned of $1,205,000 and $1,075,000 on the sinking fund as of December 31,
2017 and 2016, respectively. Interest income for the years ended 2017 and 2016 was approximately $130,000 and $86,000, respectively.
If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the sinking fund account balance in return
for complete release of liability from both us and any applicable regulatory agency using this policy as an instrument to comply
with financial assurance requirements.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also had a finite risk insurance
policy dated August 2007 for our PFNWR facility with AIG (&#8220;PFNWR policy&#8221;) which provided financial assurance to the
State of Washington in the event of closure of the PFNWR facility. The Company had recorded $5,941,000 in finite risk sinking funds
at December 31, 2016 in other long term assets on the accompanying Consolidated Balance Sheets which included interest earned of
$241,000 on the sinking fund. In April 2017, the Company received final releases from state and federal regulators for the PFNWR
policy which enabled the Company to cancel the PFNWR policy resulting in the release of approximately $5,951,000 on May 1, 2017
in finite sinking funds previously held by AIG as collateral for the PFNWR policy. The Company used the released finite sinking
funds to pay off our revolving credit with the remaining funds used for general working capital needs. The Company has acquired
new bonds in the required amount of approximately $7,000,000 (&#8220;new bonds&#8221;) to replace the PFNWR policy in providing
financial assurance for the PFNWR facility. Upon receipt of the $5,951,000 in finite sinking funds from AIG, the Company and its
lender executed a standby letter of credit in the amount of $2,500,000 as collateral for the new bonds for the PFNWR facility.
In addition, the Company&#8217;s lender imposed an additional $750,000 restriction on the Company&#8217;s borrowing availability
pursuant to a &#8220;Condition Subsequent&#8221; clause in an amendment that the Company entered into with its lender in the latter
part of 2016. Interest income earned under the PFNWR policy for the years ended December 2017 and 2016 was approximately $10,000
and $21,000, respectively.</p>

agreements with each of Mark Duff (President and CEO effective September 8, 2017, who previously held the position of EVP and COO),
Ben Naccarato (CFO), and Dr. Louis Centofanti, (EVP of Strategic Initiatives, who retired from the position of President and CEO

for three years from September 8, 2017 (the &#8220;Initial Term&#8221;) unless earlier terminated by us or by the executive officer.
At the end of the Initial Term of each employment agreement, each employment agreement will automatically be extended for one additional
year, unless at least six months prior to the expiration of the Initial Term, we or the executive officer provides written notice
not to extend the terms of the employment agreement. Each employment agreement provides for annual base salaries, performance bonuses
as provided in the MIP as approved by our Board, and other benefits commonly found in such agreements. In addition, each employment
agreement provides that in the event the executive officer terminates his employment for &#8220;good reason&#8221; (as defined
in the agreements) or is terminated by the Company without cause (including the executive officer terminating his employment for
&#8220;good reason&#8221; or is terminated by us without cause within 24 months after a Change in Control (as defined in the agreement)),
the Company will pay the executive officer the following: (a) a sum equal to any unpaid base salary; (b) accrued unused vacation
time and any employee benefits accrued as of termination but not yet been paid (&#8220;Accrued Amounts&#8221;); (c) two years of
full base salary; (d) performance compensation under the MIP earned with respect to the fiscal year immediately preceding the date
of termination; and (e) an additional year of performance compensation as provided under the MIP earned, if not already paid, with
respect to the fiscal year immediately preceding the date of termination. If the executive terminates his employment for a reason
other than for good reason, the Company will pay to the executive the amount equal to the Accrued Amounts plus any performance
compensation payable pursuant to the MIP.</p>

become exercisable in full commencing on the date of death, with such options exercisable for the lesser of the original option
term or twelve months from the date of the executive officer&#8217;s death. In the event of an executive officer terminating his

the Compensation Committee approved individual MIP for each Mark Duff, Ben Naccarato, and Dr. Louis Centofanti. Each MIP is effective
January 1, 2017 and applicable for the year ended December 31, 2017. Each MIP provides guidelines for the calculation of annual
cash incentive based compensation, subject to Compensation Committee oversight and modification. Each MIP awards cash compensation
based on achievement of performance thresholds, with the amount of such compensation established as a percentage of the executive&#8217;s
2017 annual base salary on the approval date of the MIP. The potential target performance compensation ranges approved was from
5% to 100% ($13,962 to $279,248) of the base salary for Dr. Louis Centofanti, EVP of Strategic Initiatives effective September
8, 2017 and previously the CEO and President; 5% to 100% ($13,350 to $267,000) of the base salary for Mark Duff, CEO and President
effective September 8, 2017 and previously the EVP/COO; and 5% to 100% ($11,033 to $220,667) of the base salary for Ben Naccarato,
CFO. Pursuant to the MIPs, the Compensation Committee had the right to modify, change or terminate the MIPs at any time and for
any reason. No performance compensation was earned or payable under each of the 2017 MIPs as discussed above.</p><span></span>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify">Accounts receivable are customer obligations
due under normal trade terms requiring payment within 30 or 60 days from the invoice date based on the customer type (government,
broker, or commercial). The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a
valuation allowance that reflects management&#8217;s best estimate of the amounts that will not be collected. The Company regularly
reviews all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit
worthiness, estimates the portion, if any, of the balance that will not be collected. This analysis excludes government related
receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible
are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging
category, based on historical experience that allows us to calculate the total allowance required. Once the Company has exhausted
all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment,
collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves
approvals from senior management based on required approval thresholds.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify">Unbilled receivables are generated by
differences between invoicing timing and our proportional performance based methodology used for revenue recognition purposes.
As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes the corresponding
percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to the complexity
of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones
and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially
from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical
testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks relating
to these delays usually take several months to complete. As the Company now has historical data to review the timing of these delays,
the Company realizes that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection
of some of these receivables greater than twelve months. However, our historical experience suggests that a significant portion
of unbilled receivables are ultimately collectible with minimal concession on our part. The Company, therefore, segregates the
unbilled receivables between current and long-term.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify">Unbilled receivables within our Services
Segment can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope,

contract claims and pending change orders, including Requests for Equitable Adjustments (&#8220;REAs&#8221;) when work has been

revenues using a proportional performance based methodology with its measure of progress towards completion determined based on
output measures consisting of milestones achieved and completed. The Treatment Segment has waste tracking capabilities, which it
continues to enhance, to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized
as each of the following three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However,
based on the processing of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as
sometimes they are completed concurrently. As major processing phases are completed and the costs are incurred, the Treatment Segment
recognizes the corresponding percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences
delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference
between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The
timing differences occur for several reasons, partially from delays in the final processing of all wastes associated with certain
work orders and partially from delays for analytical testing that is required after the waste is processed but prior to our release
of the waste for disposal. As the waste moves through these processing phases and revenues are recognized, the correlating costs
are expensed as incurred. Although the Treatment Segment uses its best estimates and all available information to accurately determine
these disposal expenses, the risk does exist that these estimates could prove to be inadequate in the event the waste requires
retreatment. Furthermore, should the waste be returned to the customer, the related receivables could be uncollectible; however,
historical experience has not indicated this to be a material uncertainty.</p>

price of the award, the expected term, the expected volatility of our stock over the stock-based award&#8217;s expected term,
the risk-free interest rate over the award&#8217;s expected term, and the expected annual dividend yield. The Company accounts
for forfeitures when they occur.</p><span></span>

expects to apply, if determined. Transition guidance included in certain issued but not yet adopted ASUs were also updated to

2014-09, &#8220;Revenue from Contracts with Customers&#8221; followed by a series of related accounting standard updates (collectively
referred to as &#8220;Topic 606&#8221;), which will supersede nearly all existing revenue recognition guidance. Topic 606 provides
a single, comprehensive revenue recognition model for all contracts with customers. Under the new standard, a five-step process
is utilized in order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that
reflects the consideration it expects to receive in exchange for those goods or services. Topic 606 also requires additional disclosure
surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant
judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Topic 606 is effective
for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). The
new standard permits two implementation approaches: the full retrospective method, in which case 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, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized
at the date of initial application. The Company has completed the evaluation of customer contracts and continues to identify and
implement appropriate changes to our business policies, processes, systems and controls to support the adoption, recognition and
disclosures under the new standard. The Company will adopt the new revenue standard in the first quarter of 2018 applying the modified
retrospective method. Based on our evaluation, we do not believe that the adoption of ASU 2014-09 will result in a significant
change in accounting principles applied to the Company&#8217;s financial position, results of operations or cash flows. We believe
that revenue will continue to be generally recognized consistent with our current revenue recognition model. The potential future
impacts would be limited to the capitalization of direct and incremental contract acquisition costs, which have not historically
been material. The Company will continue to monitor the materiality of these contract acquisition costs on an ongoing basis to
determine if these costs become material and should be capitalized. In accordance with the new standard, the Company will expand
revenue recognition disclosures beginning in the first quarter of 2018 to address the new qualitative and quantitative requirements.</p>
